肺结核患者外周血单个核细胞MCP-1表达上升

Objective To study the feature of MCP-1 in plasma of active pulmonary tuberculosis patients and the correlation of MCP-1 obtained from PBMCs stimulated with specific Mtb peptides with IFNγ.Methods 20 patients with active pulmonary tuberculosis and 16 healthy controls with positive PPD were enrolled.The concentration of MCP-1 and IFN-γwas analyzed with Bender Flowcytomix on flow cytometry.Results No statistical difference of MCP-1 concentration in plasma was found between TB patients and controls [(263.8 ± 25.31)pg/ml and(212.1 ± 18.04)pg/ml,P ＞ 0.05].But TB patients with continuous respiratory symptoms showed higher MCP-1 in plasma.The concentration of MCP-1 and IFN-γwas significantly elevated in PBMCs culture supernatants.It was significantly higher in TB patients than in controls [(21460 ±3376)pg/ml vs(10910 ±2141)pg/ml,P ＜0.01].There was no correlation between the concentration of MCP-1 and IFN-γ.Conclusions The concentration of MCP-1 in plasma may be related to the progress of the pulmonary tuberculosis.MCP-1 stimulated by Mtb-specific peptides may be one of the biomarkers for TB diagnosis.     

强直性脊柱炎合并骨质疏松的临床研究

Objective To investigate the incidence of osteoporosis (OP) in patients with ankylosing spondylitis and the relationship between OP and the clinical data. Methods Serum levels of bone alkaline phosphatase (BALP) and tartrate resistant acid phosphatase 5b (TRACP5b) were detected by enzyme linked immunosorbent assay ( ELISA ) in 60 cases with ankylosing spondylitis, and it was compared with normal controls. Bone mineral density (BMD) was measured through dual-energy X-ray absorptiometry ( DXA), including lumbar ( L2 - L4), bilateral femoral neck and greater trochanter. Some clinical data was collected and analyzed at the same time. Results The incidence of OP in AS patients was 35%, and the incidence of OP in the femoral proximal end was higher than that in lumbar. Compared with normal controls[ ( 1.06 ±0. 18 )U/L ], the levels of serum TRACP5b in AS[ (1.31 ± 0. 82 )U/L] patients was significantly higher ( P <0. 05 ). The levels of serum BLAP in OP combined AS group[ ( 21.65 ± 5.41 ) U/L]were significantly lower than non-OP group[ (32. 37 ± 16. 5 ) U/L] ( P <0. 05 ). The disease duration was negatively correlated with the BMD of femoral neck ( P < 0. 01 ). Conclusions There was higher incidence of OP in AS patients, which were related with the abnormality of bone metabolism and the disease duration.Multiple factors participated in the regulation of bone metabolism of AS.

Objective To explore the role of TGF-βand TGIF in the pathogenesis of endometriosis. Methods The expression of TGF-β and TGIF was detected by immunohistochemistry method in the ectopic and eutopic endometrium of 30 cases with endometriosis (ec-topic endometrium group and eutopic endometrium group) and in the normal endometrium of 40 cases without endometriosis (control group). Result The expression of TGF -β in ectopic endometrium group was significantly higher than that in eutopic endometrium group and control group (P < 0.05). There was no significant difference in the expression of TGF- βbetween eutopic endometrium group and control group(P > 0.05). The expression of TGIF in ectopic endometrium group was significantly lower than that in eutopic endometrium group and control group( P <0.05). There was no significant difference in the expression of TGIF between eutopic endometrium group and control group(P > 0.05). There were negative correlation between the expressions of TGF - β and TGIF in ectopic endometrium group and eutopic endome-trium group(rs= - 0.769, - 0.549, P < 0.05). Conclusion The abnormal expression of TGF-β and TGIF in ectopic endometrium of pa-tients with endometriosis may be associated with the genesis and progression of endometriosis.     

自身免疫性肝炎与病毒性肝炎的临床病理特点对照研究

Objective To explore the character of clinical manifestations and liver pathological features of autoimmune hepatitis (AIH) and improve the diagnostic accuracy in early stage of AIH patients. Methods 78 patients with AIH,31 patients with acute viral hepatitis(AH) and 31 patients with chronic hepatitis B (CHB) were collected. The liver function and immunoglobulins were compared among them as well as the comparison of chronic and acute onset AIH groups. A part of patients underwent liver, biopsy and HBsAg immunohistochemistry examination. Results AIH patients were dominated by female (94.87%) over 40 years old (78.21%). The level of AST/ALT, γ-glutamyl transferase (CGT), alkaline phosphatase(ALP), IgG, IgM and γ-globulin in AIH group were significantly higher than those in CHB and AH groups. Furthermore, the level of γ-globulin in chronic AIH group was higher than that in acute onset AIH group (P< 0.05). The positive rate of smooth muscle antibody(SMA) was 6.41%, and the positive rate of anti-nuclear antibody(ANA) was 79.49% in AIH patients. There was no difference in the titer of ANA between acute and chronic AIH groups(P> 0.03). Regarding the appearance of liver pathology, it was easy to distinguish AIH from AH, but difficult to differentiate AIH from CHB. liver tissues, loose degeneration, spotty necrosis and piecemeal necrosis accompanying with bridging necrosis were very common in AM. There were great numbers of lymphocyte infiltration in portal area that was often accompanied with varying degrees of fibrosis. The degree of hepatic inflammation and fibrosis were similar in acute and chronic AIH ( P > 0.05). Ihe degree of hepatic lesions in 2 AIH patients suffered with subacute liver failure didn' t agree with the severe clinical manifestations. Conclusions AIH patients are dominated with female over 40-year-old who often accompanied with elevation of AST/ALT, GGT, ALP and y-globulin as well as the appearance autoantibodies. The appearance of liver pathology is multiplicity that piecemeal of necrosis accompanying with bridging necrosis and lymphocytes infiltration is common. The degree of hepatic lesions is similar in aeute and chronic AIH. It's important to check the liver tissue for diagnose in early stage correctly.

脑血管疾病患者血清神经元特异性烯醇化酶水平变化及临床意义

To explore the application of NSE in the serum in the diagnosis of the cerebrovascular disease.Methods Serum levels of NSE from 195 patients with cerebrovascular disease and normal controls were detected with ELISA. The blood samples from the patients were acquired within 3 days after the outbreak of cerebrovascular disease and taken again after 2 weeks from 148 of all cases. The result of detecting of NSE was analysed in comparison with and the level of NSE in the CSF. Result There was significance difference between the level of NSE in the serum of patient with cerebrovascular diseases and that of normal controls when the Analysis of Variance was used to analyze the value of measurement. The same outcome was also got using ANOVA to analyze the different test group with the blood samples were acquired within 3 days. ( F = 24.94, P = 0. 000). But in the other hand, there was no evidently different in the different group made up patients if LSD was put in use instead of the ANOVA.Corelation analysis of NSE concentration was done between the in the blood samples in 3 days and those 2 weeks later (r = 0.884, t = 37.904, p = 0.000), NSE concentration in the blood samples and those in the CSF(r = 0.969, t = 8. 695, p = 0. 000), and the outcome show that there was difference between them.The same comparison between NSE concentration was done between the in the blood samples in 3 days and Head CT(r=O.857,p =O.000),Nerve Function Defect(r=0.848,p=0.000).Concluslon Thelevels of NSE in sera of patients with eerebrovascular disease were positive related with the degree of Cerebral infarction or volume of Hematoma shown by Head CT. Therefore, it would contribute to diagnosis of cerebrovascular disease if the detecting of NSE was applied in clinical laboratory.

动态血压变异性与主观认知下降进展的相关性CSCD

Objective To analyze the correlation between ambulatory blood pressure variability and the progression of subjective cognitive decline (SCD). Methods In this prospective observational study, the overall sampling method was used to continuously select 100 patients with SCD in the Department of Neurology, Changshu First People′s Hospital and Changshu Xinzhuang People′s Hospital from January 1 2016 to June 30 2017. The baseline demographic characteristics of the patients were collected. The Chinese version of SCD‑Q9 questionnaire was used to self‑evaluate SCD, and the Montreal Cognitive Assessment Scale (MoCA) was used to evaluate objective cognitive impairment. All patients received 24 h ambulatory blood pressure monitoring, and 24 h systolic coefficient of variation (SCV) and diastolic coefficient of variation (DCV) were calculated. The follow‑up period was 4 years after the first visit, and the MoCA scale was evaluated once a year. Finally, 83 patients completed the follow‑up and were included in this study. According to the MoCA score at the end of follow‑up (<26 or ≥26), the patients were divided into progression group (39 cases) and non‑progression group (44 cases). The difference of MoCA score between baseline and last follow‑up was calculated in the progression group. The difference in demographic characteristics between the two groups was compared with χ2 test. The difference of 24 h SCV and 24 h DCV between the two groups were compared by rank sum test. The correlation between 24 h SCV and MoCA score difference or SCD‑Q9 score in the progression group were tested by multiple linear regression analysis. Results The 4‑year progression rate of SCD patients was 46.99% (39/ 83). There was no significant differences in baseline age, gender, education level, medical history, smoking history, SCD‑Q9 score and MoCA score between the progressive group and the non‑progressive group (all P>0.05). The 24 h SCV in the progressive group was significantly higher than that in the non‑progressive group [13.4% (9.9%, 15.6%) vs 10.9% (9.7%, 12.7%), U=594.50, P= 0.016]. There was no significant difference in 24 h DCV between the two groups (P>0.05). In progressive group, the 24 h SCV was negatively correlated with MoCA score difference (r=-0.368, P= 0.021). Conclusion There is a correlation between ambulatory blood pressure variability and SCD progression, high 24 h SCV may be one of the factors of SCD progression and has certain predictive value. © 2023 Chinese Journal of Health Management.

慢性乙型肝炎肝组织损伤的相关因素研究

Objective To study the expression of adiponectin and α-smooth muscle actin (α-SMA) in liver from the patients of chronic hepatitis B(CHB) overlapped non-alcoholic fatty liver disease( NAFLD), and to explore the mechanism of CHB patients with NAFLD. Methods 94 patients of CHB overlapped NAFLD (case group)underwent liver biopsy, 119 cases of patients with CHB alone (control group) as control, the fasting venous blood sample was taken for liver biochemical and virological indicators. Liver biopsy specimens were immunohistochemically stained for histology, adiponectin and α-SMA, and integral absorbance. Results The serum ALT, total cholesterol, triglyceride, low density lipoprotein cholesterol and fasting glucose levels in case group were significantly higher than that in control group (Z = 3.425,4.488,4.858、2.265, P < 0.05) .There was no significant difference in HBV DNA viral load and HBeAg between the two groups( Z = 0.825, χ2 = 0.323, P > 0.05). In case group, adiponectin expression was no significant correlation with steatosis, inflammation and fibrosis(r = 0.032, -0.107, -0.133, P>0.05); however, in control group adiponectin was negatively related to inflammation and fibrosis(r= -0.223, -0.259,P<0.05). In case group,α-SMA expression was significant correlation with inflammation and fibrosis( r = 0.323,0.355, P < 0.05). In control group, its expression was no correlation with inflammation and fibrosis( r = 0.172,0.155, P > 0.05). Conclusions The occurrence of NAFLD is mainly related to metabolic factors and no relation with viral factors. Adiponectin is not directly related to liver injury of patients of CHB overlapped NAFLD. α-SMA may be important indicator of liver injury,and NAFLD may promote the progress of liver injury in patients with CHB.     

两种新型非生物型人工肝治疗慢性乙型重型肝炎疗效观察

Objective To explore the clinical effects of two new treatment methods of non-biologic artificial liver [slower plasma exchange (PE) combined with continuous veno-venous hemofiltration (CWH), and coupled plasma exchange filtration adsorption (CPEFA)] in treatment of chronic severe hepatitis B patients. Methods 130 patients with chronic severe hepatitis B were divided into three groups. 44 patients were treated with a parallel circuit of being combined slower PE and CWH based on the conservation medical therapy (group A). 43 patients were treated with CPEFA based on the conservation medical therapy (group B). 43 patients received PE with conservative medical therapy (group C). The clinical symptoms, signs, liver function, blood sodium concentration, effective rates and survival rates in three groups were surveyed before and after treatment. Results The symptom and signs of the majority in the above different groups improved. In group A and B, hyponatremia of patients were improved, the effective rates (within 6 months after the treatment) were 70.45% and 72.09% respectiverly. There was no statistical difference between the two groups (χ2=0.10,P>0.05), the survival rates(6 months) were 45.45% and 46.51% respectively and there was no statistical difference (χ2 = 0.08, P > 0.05). In group C, patients' hyponatremia did not change, the effective rate (51.16%)was obviously lower than those in group A and B (χ2 = 7.55,9.31, P < 0.01) and the total survival rate(6 months) was 30.23% also lower than those in group A, B (χ2 = 4.80,6.10, P < 0.05). Conclusions Being combined slower PE and CWH with a parallel circuit and CPEFA are two new, safe and effective methods of non-biologic artificial liver treatment.

Objective To explore the dynamic change of viral marker and clinical features in acute hepatitis B (AHB)and distinguish AHB from chronic hepatitis B(CHB) in acute onset. Methods Viral marker, HBV DNA in serum and clinical features were analyzed in 105 patients with AHB (AHB group) and 102 patients with CHB in acute onset (CHB group) between 2005 and 2009. Results There was no statistical difference in the mean levels of ALT, TBil, HBsAg, HBeAg and HBV DNA between AHB and CHB group on admission. However, the titer of auti-HBc-IgM in AHB group was(26.34 ±3.74)S/CO, which was obviously higher than that in CHB group, which was( 14.46 ± 3.10)S/CO, there was a statistical difference between the two groups( P < 0.05). After 2 weeks treatment, the levels of ALT and TBil in AHB patients decreased (1540.50±225.54)IU/L and (103.60± 46.48) μmol/L respectively, the decreased levels in AHB group were high compared to CHB group; the levels of HBsAg, HBeAg and HBV DNA in AHB group decreased (2558.46 ±644.26) IU/mL, (420.20± 63.20) S/CO and (4.53± 1.42) log10copies/mL respectively, and the levels decreased obviously compared to CHB group (P < 0.05). The decreased level of anti-HBc-IgM in AHB group was no statistical difference to CHB group after 2 weeks treatment (P > 0.05). 19.04% of the AHB patients were HBV DNA negative seroconversion before they were hospitalized. The level of HBsAg and HBeAg in AHB group declined quickly. Separately, 90.47% and 94.24% of the AHB patients had HBsAg and HBeAg seroconversion at the end of follow-up in AHB group. The level of ALT in AHB decreased quickly but its normalization was slower than the clearance of HBV. Conclusions There is no difference in viral marker, HBV DNA and clinical features between AHB and CHB in acute onset patients on admission, but the recovery of liver function in AHB is obviously after treatment. Anti-HBc-IgM (≥20 S/CO), dynamic change and seroconversion viral marker, ALT ≥20×ULN and recovery can be used to differentiate AHB from CHB in acute onset.

Objective To investigate Fascin expression in human lung cancer tissues and its clinical significance.Methods Immunohistochemistry was performed in 62 patients with different histological types and clinical stages of lung cancer and 92 cases with other malignant tumors.Fascin positive rate in each group was calculated and the differences of pathological characters between the two groups were analyzed.Results Fascin expression in lung cancer tissues was significantly higher than that in normal lung tissues(P ＜ 0.05),its expression varied by different clinical stage of lung cancer tissue differentiation.As differentiation degree decreased,Fascin positive rate increased.Fascin expression was independent with age,sex,smoking history(P ＞ 0.05).Fascin expression had no significant difference between lung cancer group and other tumor group(P ＞ 0.05).Conclusions Fascin expression raising might be common in malignant tumors.Fascin expression in lung tissues indicated the possibility of lung cancer.In lung tissue,high expression of Fasein was a sign of poor differentiation and malignant status of lung cancer.     

西安地区92例帕金森病患者药物治疗情况调查

Objective To investigate the treatment status of antiparkinsonism in Xi'an. Methods Six general hospitals were randomly chosen in Xi' an and all Parkinson' s disease (PD) patients were interviewed by questionnaire from Jan. 2007 to Apr. 2007. Results 92 PD outpatients were enrolled in, including 48 males and 44 females, from 43 to 86 years old (mean 65.6±17.1) with duration of the disease from 0.2 to 27.8 years (mean 4.4 ±9.4). The preference of the drug use from the patients were: 40 (43.5%) preferred taking levodopa, 25 (27.2%) with amantadine and/or trihexyphenidyl, 14(15.2%) with levodopa and others, 4(4.4%) with dopamine agonist and others, 2 (2.2%) with other drugs, 7 (7.6%) with no treatment. There were 69 (75.0%) patients onset with resting tremor, 15 (16.3%) with bradykinesia, 6 (6.5%) with rigidity, and 2 (2.2%) with unknown symptoms. There was no startically significant difference in anti-PD drugs among the patients onset with different symptoms (P>0.05). 45 patients appeared the onset of disease before 65 years old and with no dementia, 47 onset after 65 with or without dementia. There was no significant difference of anti-PD drugs between the two groups (P>0.05). Most patients initiated anti-PD treatment with levodopa but few of them chose dopamine agonist. According to the classification of Hoehn & Yahr, 25(27.2%) belonged to Grade Ⅰ, 53(57.6%) to Grade Ⅱ ,8(8.7%) to Grade Ⅲ ,3(3.3%) to Grade Ⅳ and 3 (3.3%) to Grade Ⅴ. There was no significant differences of anti-PD drugs between different grades of the disease (P>0.05). 55.3% of the patients changed their anti-PD drugs randomly during the therapy, but with no relation to their gender, age, educational level, dementia, the number of family members, course of diseases, or the degree of Hoehn & Yahr, frequency and categories of medicine. Conclusion Anti-PD treatment in Xi' an did not strictly follow the standardized protocol, with few patients using dopamine agonist and over 50% of the patients changed their drugs randomly.     

Influencing factors of post stroke cognitive impairment in patients with acute ischemic stroke and their correlation with cognitive scoresCSCD

Objective To analyze the influencing factors of post stroke cognitive impairment (PSCI) and their correlation with cognitive scores in patients with acute ischemic stroke. Methods In this cross‑section study, 36 patients diagnosed with acute ischemic stroke and post stroke cognitive impairment (PSCI) admitted to the Department of Vascular Neurology of Beijing Tiantian Hospital Affiliated to Capital Medical University from June 1, 2022 to September 30, 2022 were selected as the PSCI group. And one to one matching was performed for patients without PSCI (PSNCI group) with an age±1 year and same gender admitted to the hospital during the same period (as control, 36 cases). Basic clinical data of the two groups were collected, the laboratory and imaging examinations were completed. Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) were used for cognitive evaluation by neuropsychologists. Hypothesis testing was used to compare the differences in basic data, laboratory tests and lesion sites between the two groups. Multi‑factor conditional logistic regression was performed to analyze the influencing factors of PSCI, and Spearman correlation analysis was carried out to analyze the correlation between influencing factors of PSCI and the cognitive scores. Results Compared with those in PSNCI group, the proportion of patients with stroke/transient ischemic attack history, hyperhomocysteinemia (HHcy), apolipoprotein E(ApoE) ε4 carriers and the ratio of temporal lobe and thalamus infarction were higher in PSCI group (41.7% vs 13.9%, 36.1% vs 2.8%, 30.6% vs 5.6%, 22.3% vs 2.8%, 25.0% vs 5.6%), the MMSE and MoCA scores were lower in PSCI group [16.50 (8.25, 19.00) vs 28.00 (27.00, 30.00), 10.00 (4.25, 14.50) vs 27.00 (25.00, 28.00)] (all P<0.05). Logistic regression analysis showed that HHcy was a positive correlation factor for PSCI (OR=2.342, 95%CI= 1.186-4.622, P=0.014). Spearman correlation analysis showed that MMSE (r=-0.415) and MoCA (r= -0.417) scores were negatively correlated with homocysteine (Hcy) (both P<0.05). Conclusion HHcy is an important factor affecting the occurrence and development of PSCI in patients with acute ischemic stroke, and Hcy level is negatively correlated with cognitive scores in those patients. © 2022 Chinese Medical Journals Publishing House Co.Ltd     

降钙素对大白兔糖尿病骨质疏松模型假体骨密度及生物力学的影响

Objective To investigate the influence of calcitonin on bone mineral density and biomechanics around the artificial pros-thesis in ovariectomized diabetic rabbit model. Methods Fourteen femina New Zealand white rabbits at the age of 5 months old were select-ed, which weight 2.24 -2.65kg, averaging 2.26kg. First, the model of rabbit with diabetic osteoporosis was successfully established by the compound method of ovariectomy plus streptozotocin. Osteotomy in the middle part of femur was performed in both groups, fixation of artifi-cial prosthesis was done with 3.0 kirschner wire. After that, Rabbit models with diabetic osteoporosis were randomly divided into experimen-tal group and control group. Rabbits in the experimental group were treated with calcitonin 6U intramuscular injection once every other day. In control group, intramuscular injection of normal saline solution 1.5ml once every three days. Rabbit models of two groups were sacrificed in the 24th week. The BMD of the region of interest (ROI) around the prosthesis were detected before experiment and 8, 16 and 24 weeks after injection. After rabbits were killed, experimental femurs in both groups were complete removal and soft tissues were rejected. Determi-nation of the pull-out and torsion bone biomechanics experiments of prosthesis was done in both groups respectively. Results The BMD of ROI in the experimental group before operation was (0.1863±0.004)g/cm2 and (0.1753±0.005)g/cm2 in 24 weeks after operation, in control group before operation was (0.1865±0.002)g/cm2 and (0.1638±0.005)g/cm2 in 24 weeks after operation. There were significant difference between the two groups(P < 0.05). Biomechanical show that the pull-out strength in the experimental group was (312.68±8.73 )N/cm2 and (205.43±12.45 ) N/cm2 in control group. There were significant difference between the two groups(P < 0.05). The tor-sion strength in experimental group was (80.47±2.51) N/cm2 and (38.52±0.64) N/cm2 in control group. There were significant differ-ence between the two groups(P < 0.05). Conclusion Salmon calcitonin can reduce the bone turnover rate around prosthesis and decrease bone absorption in the rabbit of diabetic osteoporosis models, accelerate the bone formation around prosthesis, and increase the BMD. It can ameliorate the quality of bone around prosthesis, improve its biomechanics property, and increase the holding power between prosthesis and body mass. It is of clinical significance for the prevention and treatment of aseptic loosening artificial prosthesis.     

新兵人群A群流行性脑脊髓膜炎抗体的血清流行病学调查

Objective To investigate the distribution of serogroup A epidemic cerebrospinal meningitis antibody IgG in recruits, provide scientific evidence for further prevention and control of the disease. Methods By using ELISA, serogroup A epidemic cerebrospinal meningitis antibody IgG serum samples of 360 recruits, who came from 7 provinces during the past four years, were detected, and the positive rate was analysed. Results There was no statistical difference in serum serogroup A epidemic cerebrospinal meningitis antibody IgG levels in each years, which ranged from 66.67% to 96.67% with a average rate of 83.33%, content of antibody ranged from 6.23 μg/mL to 26.47 μg/mL with an average content of 12.42 μg/mL, regional difference existed. The higher level found in recruits from Hubei (96.67%) 、Shandong (91.43%)and Beijing (88.00%), and lower level from Henan (66.67%) and Shaanxi(72.50%). There was no significant correlation between the antibody IgG positive rate and education or occupation background of the recruits before their recruitment (χ2 = 0.12, P > 0.05). Conclusions The positive rate of serogroup A epidemic cerebrospinal meningitis antibody IgG in recruits range from 66.67% to 96.67%, antibody level range from 6.23 μg/mL to 26.47 μg/mL, with a average content of 12.42 (μg/mL. The positive rate for antibody IgG varies in different provinces. It is necessary to give vaccination and education for the recruits to prevent serogroup A epidemic cerebrospinal meningitis spreading.

狼疮性肾炎患者血清IL-6、sIL-2R水平测定

To investigate the Changes of sIL - 2R, IL - 6 level in ,serum of patients with lupus nephritis and its clinical meaning. Methods The level of serum sIL - 2R, IL - 6 in 42 cases of lupus nephritis were detected by ELISA, and the data were compared with control group. Results Serum sIL- 2R ,IL-6 levels in lupus nephritis patients were significantly higher than control group and related to convalescent of the disease. Conclusion It suggested that immune dysfunction exist in patients with lupus nephritis higher level of sIL-2 ,IL-6 would associate with genesis and development of lupus nephritis, and it can be a new indicator of lupus nephritis.     

胰岛素抵抗及血清瘦素异常与糖尿病合并脂肪肝的关系研究

Objective To study the relations among insulin resistance,abnormality of serum leptin level soluble leptin receptor(sLR) and the development of fatty liver in type 2 diabetes mellitue (DFL), so as to detect the partial pathogenesis. Methods 196 patients with type 2 diabetes mellitus were selected to retrospective study. The DFL group consisted of 96 patients who had already developed to fatty liver, while the NDFL group included 100 patients with no fatty liver. Biochemical test and insulin resistance were analysisd, and the level of serum leptin and sLR were also examined. Results The level of blood triglyceride(TG), high density lipoprotein(HDL), very low density lipoprotein( VLDL) between two groups were all statistical differences (t = - 8.124, 4.882, - 3.576, P < 0.01). The TG, HDL and VLDL level in DFL group were (3.25 ± 1.92), (1.11 ±0.28), (1.53 ± 0.60) mmol/L respectively. There was also a statistical difference in HOMA-IR level between the two groups (t = - 4.748, P < 0.01). HOMA-IR in DFL group was (4.82± 2.94), but no statistical difference in secretive function of beta cells (t = 0.123, P > 0.05). There was statistical difference in level of serum leptin and sLR between the two groups (t = - 7.435,13.332, P < 0.01); the leptin and sLR in DFL group were (4.34± 2.05) and (1.71 ± 0.53) fig/L respectively. Meanwhile, Pearson analysis showed that the blood TG level of the DFL group was positively correlated with HOMA-IR and leptin ( r = 0.845, P< 0.01; r = 0.742, P< 0.01); serum leptin level was positively correlated with HOMA-IR level (r = 0.852, P<0.01). However, serum sLR level showed negative correlation ( r = - 0.587, P < 0.01). Conclusions Insulin resistance and abnormality serum level of leptin and sLR might be one of the important causes for DFL, while abnormal lipid metabolism might be the secondary cause for this biochemical change.
