Prevalence and risk factors associated with chronic kidney disease in a Uygur adult population from Urumqi

Evaluating the prevalence of kidney damage according to population-based studies in different communities has been limited in developing countries.We conducted a population-based screening study in Uygur people of Urumqi, aiming to identify the prevalence and associated risk factors of chronic kidney disease (CKD) in Uygur populations.A total of 2576 residents (>18 years) from four districts of Urumqi were interviewed from June 2007 to January 2009 and tested for haematuria, albuminuria and reduced renal function.Associations between age, gender, smoking, diabetes mellitus, hypertension, hyperuricaemia and kidney damage were examined.There were 2576 subjects enrolled in this study.After age correction, the prevalence of albuminuria, haematuria and reduced estimated glomerular filtration rate (eGFR) was 3.58%, 2.26% and 1.03%, respectively.Approximately 5.65% of the sample population had at least one indicator of kidney damage.Age, diabetes mellitus, hypercholesteremia, hyperuricaemia and hyperlipidaemia were independently associated with CKD.In the general Uygur adult population from Urumqi, 5.65% had either proteinuria, haematuria or reduced eGFR, indicating the presence of kidney damage, with an awareness of only 1.05%.The high prevalence and low awareness of CKD in this population suggest an urgent need for CKD prevention programs in Uygur people.     

Efficacy and safety of vitamin D3 in patients with diabetic nephropathy: a meta-analysis of randomized controlled trials

Background Several studies found that vitamin D3 might alter glucose metabolism,protect kidney from injury and even proposed the mechanisms.But results from previous studies have been conflicting.The aim of this study was to evaluate the efficacy and safety of vitamin D3 in patients with diabetic nephropathy.The underlying mechanism of vitamin D3 decreasing proteinuria is also discussed.Methods We conducted a search of English and Chinese articles using database of Pubmed,Embase,Sinomed,CNKI,Wanfang and clinical trial register centers,for randomized controlled trials of vitamin D3 in diabetic nephropathy patients.Two reviewers performed independently.Meta-analysis was used when studies were homogeneous enough.Results Twenty studies,including 1 497 patients with diabetic nephropathy,were involved in this systemic review.Vitamin D3-treated patients with diabetic nephropathy had a statistically significant reduction in 24-hour proteinuria （weighted mean difference-0.44,95% CI-0.54 to-0.34,Z=8.80,P 〈0.000 01） and urine albumin/creatine ratio （standardized mean difference-0.29,95% CI-0.48 to-0.10,Z=2.96,P=0.003）.But vitamin D3 supplementation did not significantly reduce blood pressure and hemoglobin A1c compared with control group.The potential mechanisms about the renal protection of vitamin D3,including the inhibition of rennin-angiotensin system,the protection of kidney from inflammation,fibrosis and the structure change of kidney are discussed.In addition,vitamin D3 did not significantly increase the incidence of adverse effects,including total adverse effects,gastrointestinal adverse effects and fluctuation of blood pressure.Conclusions Vitamin D3 can ameliorate proteinuria and protect kidney from injury in patients with diabetic nephropathy.This renoprotective effect is independent of blood pressure and glucose reduction.And it does not increase any adverse effects than control,even in combination therapy with angiotensin converting enzyme inhibitors/angiotensin receptor blockers.But due to the limite     

Effect of scraping therapy on Interleukin-1 in serum of rats with lumbar disc herniation

OBJECTIVE:To explore the effect of scraping therapy on the Interleukin-1 (IL-1) levels of rats with lumbar disc herniation (LDH). METHODS: Fifty male rats were devided into a blank group (A), a sham operation group (B), a model group (C), a scraping group (D), and a drug group (E). The rats in the group B were treated with sham operation, and groups C, D and E were made into the LDH model by operation. After operation group C were treated with no interventions, D were given scraping and E were fed with azathioprine Then the IL-1 levels of different groups were detected by enzyme-linked immuno sorbent assay method. And the transplanted coccygeal vertebra discs were observed by pathological section. RESULTS: The IL-1 levels in the groups C, D, and E were significantly higher than those in the groups A and B (all P<0.01), which proved the operationwas successful.The IL-1 levels in the groups D and E at different periods had statistical significance (F= 414.158, P<0.01). The treatment periods and interventions have interation (F=46.613, P<0.01). Multiple comparison results showed that the IL-1 levels in the groups D and E was significantly lower than that in the group C (P<0.01), while the IL-1 levels between the groups D and E had no statistical significance (P>0.05). Moreover, pathological section indicated that immuno-inflammatory response was hardly found in coccygeal vertebra discs in the groups A and B, while local immuno-inflammatory responses of the groups D and E were much lighter than that of the group C. CONCLUSION: Scraping therapy could inhibit the immuno-inflammatory responses in the rats with LDH caused by transplantation of autologous nu cleus pulposus.     

The Effect of Vitamin A on Secretion of IFN-γ and IL-4 in A549 Cells Induced by Mycoplasma Pneumoniae

In order to investigate the effect of vitamin A (VA) on the secretion of IFN-γ and IL-4 in Mycoplasma Pneumoniae (MP)-induced A549 cells, A549 cells were co-cultured with MP for different time lengths and then the levels of IFN-γ and IL-4 in the cell culture supernatants were detected before and after treatment with different concentrations of VA by using the enzyme-linked immu-nosorbent assay ( ELISA). The results showed that the level of IFN-γ and IL-4 in the supernatants of MP-induced A549 cells was much higher than that in non-induced cells (P<0.01). After application of VA, IL-4 level was not increased until the concentration of VA was up to 0.5×10-5 mol/L (P<0.01). However, with concentration of VA increased up to 1×10-4 mol/L, IL-4 was significantly suppressed (P<0.01). It was concluded that MP could induce the secretion of IFN-γ and IL-4 in A549 cells. VA could inhibit the secretion of IFN-γ and increase the IL-4 level in MP-induced A549 cells. However, high concentration of VA had an inhibitory effect on the secretion of IL-4 as well as on the IFN-γ. These data provided a theoretical basis for the application of VA in MP pneumonia in the clinical practice.     

Clinical Study on Yishen Qufeng Shengshi Recipe (益肾祛风胜湿方) for Glomerular Proteinuria Patients: A Randomized Controlled Trial

Objective: To explore the therapeutic effect of Yishen Qufeng Shengshi Recipe(益肾祛风胜湿方,YQSR) in patients with glomerular proteinuria. Methods: A total of 145 patients with glomerular proteinuria were selected and randomly assigned to the treatment group(108 cases) and the control group(37 cases) according to a random number table in a ratio of 3:1. All patients received conventional and symptomatic treatment. In addition, patients in the treatment and control groups were given YQSR(200 m L, twice per day, orally) and losartan(50 mg/d orally), respectively for 6 months. The 24-h urine protein quantity, blood urea nitrogen, and serum creatinine in the two groups were measured at multiple time points before and after treatment. Results: At the end of the study, 5 cases were lost to follow-up in the treatment group and 1 in the control group. Finally, the statistical data included 103 cases in the treatment group and 36 cases in the control group. The total effectiveness after 2, 4, and 6 months was 81.6%(84/103), 87.4%(90/103), and 92.2%(95/103), respectively, in the treatment group and 47.2%(17/36), 55.6%(20/36), and 61.1%(22/36), respectively, in the control group, with significant difference between the two groups(P0.01 at all observation points). In the treatment group, the curative effect after 6 months was better than that after 2 months(P0.05). The 24-h urine protein quantity was significantly lower in the treatment group at 3, 4, 5, and 6 months than that in the control group(P0.05 or P0.01, respectively). Conclusion: YQSR could significantly reduce the amount of glomerular proteinuria in the early stage.

Correlation between podocyte excretion and proteinuria in diabetic nephropathy patients

Objective： To observe the podocyte injury in diabetic nephropathy （DN） patients by identifying the urinary podocytes and the situation of detached podocytes in glomeruli and to demonstrate the correlation between podocyte excretion and proteinuria, blood glucose, serum creatinine in different phases in DN patients. Methods： Urinary podocytes and the podocalyxin （PCX） expression state of podocytes in glomeruli were identified and observed by indirect immunofluorescent method. The DN patients were divided into three groups according to the volume of proteinuria, namely small, medium and large volume proteinuria groups. The podocytes in the urine of every group were calculated. The DN patients were divided into five groups according to the chronic kidney disease （CKD） phases, then the positive podocytes in urine were calculated. Meanwhile, the 24-hour protein in urine, fasting blood glucose （FBG） and the serum creatinine of DN patients were tested. The correlations among the proteinuria, serum creatinine, FBG and the number of positive podocytes in the urine of DN patients were statistically analyzed. Results： Urinary positive podocytes were found in 88% of the patients with DN, whereas podocytes were found in 0% of patients with minimal changed disease （MCD） and healthy cases. The expression of PCX was absent in DN patients. In contrast, PCX was expressed integrally in MCD patients. The positive podocytes was 1.49±0.95/ml in small-volume proteinuria group, 2.15±0.70/ml in the medium-volume proteinuria group, and 3.48±1.27/ml in the large-volume proteinuria group. There was no significant difference between the small- and medium- volume proteinuria groups, and there were significant differences between other groups （P〈0.05）. The positive podocyte number tended to increase as proteinuria was increased. By Pearson analysis, the correlation between podocyte number and proteinuria was podocytes in urine from different groups of DN patients, CKD pc I sitive statistically. The difference of the number of positive -V group was significant statistically. The correlation between serum creatinine of CKD Ⅰ -Ⅲ group and positive podocytes in urine was positive statistically. The correlation between serumcreatinine of CKD Ⅳ- Ⅴ group and positive podocytes in urine was not significant statistically. The correlation between FBG and positive podocytes in urine was not significant either. Conclusion： The mechanism of the podocyte injury in DN patients is present. The podocyte injury in DN may positively correlate to proteinuria and serum creatinine of CKD Ⅰ -ⅢDN patients, but not to the FBG and serum creatinine of CKD Ⅳ-Ⅴ patients.
