不同治疗方案对多发性骨髓瘤患者骨病的影响

Objective To explore the difference of effects of two regimens (bortezomib and dexamethasone, BD; and thalidomide and dexamethasone, TD) on bone disease in multiple myeloma(MM).Methods Forty patients with newly diagnosed and refractory or relapsed MM were treated with BD or TD regimens from Dec 2006 to Sep 2008. Bone pain score and X-ray examination were carried out before and after therapy. Serum levels of DKK-1, sRANKL, OPG and TRACP-5b were measured by ELISA before and 3 months after therapy. Results Serum TRACP-5b concentration was significantly decreased in patients received TD regimen (5.94 U/L before therapy vs 4.84 U/L 3 months after therapy ,P ＜ 0.05), and so did for serum DKK-1 concentration in patients responded to BD regimen (35.11 μg/L before vs 32.03 μg/L 3 months after therapy,P ＜0.05) ;for serum concentration of sRANKL in patients responded to BD regimen (1.05 pmol/L before vs 0.67 pmol/L 3 months after therapy, P ＜ 0. 05); and for serum concentration of TRACP-5b in responders to BD regimen (5.57 U/L before therapy vs 4.90 U/L 3 months after therapy ,P ＜0.05). Conclusion Bortezomib lowers levels of serum DKK-1 and RANKL in responders, thus leads to normalization of abnormal bone remodeling through the increase of bone formation and reduction of bone resorption. Thalidomide decreases bone resorption regardless of treatmant response.

The influence of modified electrocomulsive therapy on serum interleukin—6 in schizophrenic patients

AIM：To explore the influence of modified electroconvulsive therapy on serum interleukin-6 in schizophrenic patients.METHOD:Testing change of serum IL-6 in 60 cases treated with MECT and 60 control cases treated with clozapine therapy by ELISA method. RESULTS:Serum IL-6 level before treatment of both groups was positive related to SAPS; serum IL-6 level wasn′t related to BPRS total score, factor score and SANS total fractions. IL-6 level of clozapine therapy group decrease apparently after treatment, and IL-6 level was apparently positive related to anxious depressed factor of BPRS; but there was no apparent difference in IL-6 level of MECT group between before and after treatment.CONCLUSION:To schizophrenic patients, clozapine can take effects of immune inhibit through inhibiting serum IL-6; MECT may have different mechanism.     

Anti-virus efficacy of cyclosporine in renal transplant recipients with hepatitis C virus-RNA positive

BACKGROUND:The selection of immunosuppressants and anti-hepatitis C virus drug is currently the focus for the hepatitis C virus-positive patients after receiving renal transplantation. OBJECTIVE:To investigate the anti-virus replication effect of cyclosporine in hepatitis C virus-RNA positive renal transplant recipients in addition to its anti-rejection effect. METHODS:Eleven hepatitis C virus-RNA positive renal transplant recipients were enrol ed and treated with cyclosporine, prednisone and mizoribine. Hepatitis C virus-RNA level, hemoglobin, liver functions and renal functions were evaluated before treatment and at 6 and 12 months after treatment. RESULTS AND CONCLUSION:The median of hepatitis C virus-RNA in 11 patients before treatment, and at 6 and 12 months after treatment were 1.22×107 copies/mL,1.11×104 copies/mL and 4.19×106 copies/mL respectively. At 6 months after treatment,8 cases of hepatitis C virus-RNA were negative (hepatitis C virus-RNA<500 copies/mL), and the total response of hepatitis C virus-RNA was 73%, and the sustained virological response was 55%(6/11) at the final fol ow-up. There was no significant difference of alanine transaminase, serum creatinine and serum uric acid levels before and after treatment (P>0.05), and the hemoglobin level was increased after treatment. During the fol ow-up, acute rejection only occurred in one patient and was control ed within 3 days after methylprednisolone pulse therapy. Cyclosporine-based treatment would be a better choice for renal transplant recipients combined with hepatitis C virus infection for both the anti-virus replication and anti-rejection effect.

阿托伐他汀对老年脑梗死伴高血脂患者颈动脉粥样硬化斑块的影响

Objective To investigate the effect of atorvastatin on arteriosclerosis plaque of carotid artery in elder patients with cerebral infarction and hypercholesterolemia. Methods With self-comparsion of before and after treatment,50 subjects with arteriosclerosis plaque of carotid artery were given atorvastatin 10 mg,qn for 12 months. After treatment 6 and 12 months, arteriosclerosis plaque of carotid artery、 intima-media thickness and peak index were measured in all patients. Results After 6 and 12 months adminstration of atorvastatin, TC、TG、LDL-C were all reduced (P<0.05), and HDL-C was elevated (P<0.01) in all patients.The initial diameter of carotid was significantly enlarged in 12 months (P<0.01). The size of plaque decreased (P<0.01) in 12 months after atorvastatin therapy than before(P<0.01). Conclusion The effect of atorvastatin is certain and it can stabilize the plaque of carotid artery.     

Effect of selective and non-selective <Emphasis Type="Italic">β</Emphasis>-blockers on body weight,insulin resistance and leptin concentration in chronic heart failure

Background Chronic heart failure (CHF) is characterized by increased insulin resistance and hyperleptinaemia. We aimed to study effects of selective and non-selective β-blockers on body weight, insulin resistance, plasma concentrations of leptin and resistin in patients with CHF. Methods Twenty-six non-cachectic β-blocker-naive patients with CHF were randomized and treated with either carvedilol or bisoprolol. Body weight, plasma concentrations of leptin, resistin, fasting glucose and insulin were measured at baseline and after 6 months of therapy. Insulin resistance was estimated by homeostasis model assessment- estimated insulin resistance (HOMA-IR). Results Body weight increased significantly in the carvedilol group (mean change + 2.30 kg, p = 0.023) while it did not change in the bisoprolol group (mean change –0.30 kg, p = 0.623) (ns between groups). Plasma leptin concentration increased only in the carvedilol group (mean change + 4.20 ng/ml, p = 0.019) (ns between groups). Fasting glucose and resistin remained unchanged in both groups. After 6 months, mean plasma insulin concentration changed significantly differently (p = 0.015) in the bisoprolol (mean change +3.1 μU/ml) compared to the carvedilol group (mean change –6.3 μU/ml) and HOMA-IR was consequently higher in the bisoprolol compared to the carvedilol group (5.2 ± 4.2 vs 2.8 ± 1.6, p = 0.046). Conclusion This study found different metabolic effects of carvedilol and bisoprolol in non-cachectic patients with CHF. With unchanged fasting plasma glucose concentration after 6 months of treatment, carvedilol significantly decreased plasma insulin concentration and insulin resistance compared to bisoprolol.

慢性特发性血小板减少性紫癜患者血清转化生长因子β1测定的意义

Objective To investigate clinical significance of transforming growth factor-beta 1 ( TGF-β1 ) in patients with chronic idiopathic thrombocytopenic purpura(CITP). Methods The serum level of TGF-β1 in 38 pa-tients with initial CITP were detected using enzyme-linked immunosorbent assay(ELISA). Results The serum level of TGF-β1 in initial patients with CITP was significantly higher than that of the controls [( 132.57±5.17) μg/L vs ( 76.81±4.42) μ/L] ( P <0.01 ). The serum level of TGF-β1 in those having good response after therapy was sig-nificantly lower than before treatment[(81.26±3.78)μg/L] (P <0.01 ). There was no difference in TGF-β1 be-tween nonremission [(123.49 ± 4.31 ) μg/L] and initial patients (P > 0.05 ). There was negative correlation between TGF-β1 and platelet count(r = -0. 342 ,P < 0.05 ) ,there was positive correlation between TGF-β1 and megakaryo-cyte count (r = 0.409, P < 0.01 ). Conclusions TGF-β1 partakes in the pathogenesis of CITP, the determination of which in patients with CITP is useful to judge the state of illness, which can be regarded as an assistant index of cur-ative effect.

The characteristics of interpretation of results of analysis of protein amount in urine of pregnant women

The adequacy of implementation of present proteinuria diagnostic thresholds under examination of pregnant women was examined. The analysis was applied to all urine samples of pregnant women from December 2009 to March 20010. The amount of protein in urine was concurrently evaluated by turbidimetric analysis with sulfosalicylic acid, colorimetric analysis with pyrogallol red, "dry chemistry" technology (the diagnostic strips). It is established that the mentioned techniques of analysis of protein in urine provide independent results. The results of colorimetric analysis are characterized by better precision and adequacy. However, in case of pregnant women the diagnostic threshold of protein concentration should be shifted from 0.120 to 0.150 g/l.
