AIM: To establish HPLC method for the determination of berberine hydrochloride in Huanglianshangqing Tablets(Rhizoma Coptidis, Radix et Rhizoma Rhei, Fructus Forsythiae, etc.). METHODS: The Diamonsil TM C 18(20cm?4.6mm,5?m) was used with 0.033mol?L -1 Potassium dihydrogen phosphate solution-acetonitrile (70∶30) as a mobile phase. The flow rate was 1.0 mL?min -1. The detecting wavelength was 265nm. RESULTS: The linear of berberine hydrochloride was in the range of 0.2376～ 0.5544?g, r= 0.9999. The average recovery was 98.7% and RSD was 0.7%(n=5), respectively. CONCLUSION: The method is simple,rapid and accurate.

Objective To evaluate the soothing effects of hemodiafiltration on patients with refractoriness nephrotic edema and its influence on prognosis of nephrotic syndrome.Methods All the 15 cases involved had undergone hemodiafiltration periodically during acme edema and administered with the same standard loading dose of prednisone for 8 weeks.Meanwhile,clinical and lab indexes (urine volume,Cr,Bun,urinary protein,albumin) were measured.Results All patients improved in urine volume and renal function gradually after the treatment of hemodiafiltration for 1 to 3 times.By the 8th week of post-hemodiafiltration,urinary protein 24 h declines obviously[(6.42?2.31)g/d to (0.87?1.24)g/d].Conclusion Hemodiafiltration is an effective treatment in relieving retention of water,increasing the remission rate of protein urine,recovering patients' renal function and improving their prognosis to nephritic syndrome patients with severe refractory edema.

Aquaporin adipose (AQPap) is the physiological glycerol channel specific to adipocytes. By means of semiquantitive RT-PCR and Western blotting, this study showed that insulin was a negative regulator of AQPap expression, while high concentration of glucose could increase AQPap expression.

ObjectiveTo investigate the treatment and safety of interferon ? plus Ribovirin for chronic hepatitis C after kidney transplantation. MethodsFive patients with chronic hepatitis C after kidney transplantation were administered with interferon ? (50 ?g) subcutaneously once a week, plus Ribovirin (600 mg) orally once daily. The levels of HCV-RNA, ALT and serum creatinine in patients’ serum were monitored monthly. ResultsFour in 5 patients presented normal ALT and negative HCV-RNA in serum 12 weeks after treatment, and obtained sustained viral response 24 weeks after interferon ? plus Ribovirin therapy. During treatment, renal graft rejection did not occur. The most frequent side-effects were the decrease of leukocyte and hemoglobin, myalgia and fever, but did not influence the course of treatment. ConclusionCombination of interferon ? with Ribovirin can be a valid therapeutic option in renal transplant recipients with hepatitis C, and shows no influence on the renal function.

ObjectiveTo explore the clinical and pathological characteristics in diagnosing the renal diseases with diffuse glomerular nodular changes. MethodsThe clinical and pathological data of 127 patients whose renal pathological feature was mainly diffuse glomerular nodular changes were retrospectively analyzed. ResultsThe most common diagnosis was diabetic nephropathy and renal amyloidosis, and sometimes light chain deposit diseases and Mix cryoglobulinemia. ConclusionDiffuse glomerular nodular changes occurred in many diseases. We should make differential diagnosis based on the clinical symptoms, the results of laboratory examinations and the renal pathological characteristics.

Objective To observe the impact of transplant nephrectomy on panel reactive antibodies and a secondary renal transplantation.Methods Panel reactive antibodies in 15 patients with a failed renal transplant admitted in our hospital between 2004 to 2007 were measured before transplantation,before and 1 month,6 months,12 months after transplant nephrectomy,and the pathological changes were observed after transplant nephrectomy.Results Panel reactive antibodies was increasing after renal transplantation,and reached the highest level one month after transplant nephrectomy,then grandually got down.New HLA allosensitization sites were discovered after transplant nephrectomy.Large amount of C4d was stained in failed transplant.Conclusion Serum PRA increased after transplant nephrectomy.New HLA allosensitization sites were found,which may be useful in HLA matching.

Insulin like growth factor-Ⅰ (IGF-Ⅰ) gene was transferred to diabetic rats with intramuscle gene therapy pathway. It was showed that IGF-Ⅰ gene could express in the body and the blood glucose level was significantly decreased with increasing of serum IGF-Ⅰ.

A total of 1342 individuals underwent physical examinations according to the criteria of metabolic syndrome of International Diabetes Federation (IDF) in 2005.And 314 patients with metabolic disorders were screened for diabetes by standard meal and methods oral glucose tolerance test (OGTT).Newly diagnosed diabetics was 12 (4.1％ ) vs.17 (5.8％) respectively.No significant difference existed between two methods (P =0.332).Kendall's (τ)b =0.313,Kendall's (τ)c =0.208 and Gamma coefficient =0.580 (P =0.000).The mixed meal method was correlated with OGTT,Kappa =0.258 (P =0.000) and two methods were consistent.Diabetic screening should be stressed in the subjects with metabolic abnormalities.And the detecting efficiency of postprandial plasma glucose is similar to OGTT.

Objective To evaluate the influence factor of 'SF-FDG and 18F-FLT PET/CT for diagnosing pulmonary nodules.Methods 55 patients with pulmonary nodules were chosen as study target,include 33 male cases and 22 female cases,the age range from 17 to 82 years old.In all cases,28 cases had one pulmonary nodule,others had 2 or 3 pulmonary nodules,and the nodule size was 0.6-11.0 cm.18F-FDG and 18F-FLT PET/CT were performed on 55 patients.The relationship of SUV of 18F-FDG and 18F-FLT with sex,age,size and pathology of all pulmonary nodule patients were analyzed.Results The SUV of 18F-FDG and 18F-FLT had no statistics difference on sex,age and size(P>0.05),the SUV of 18F-FDG had no statistics difference on pathology of pulmonary nodule(P>0.05).Otherwise,the SUV of 18F-FLT had statistics difference on pathology of pulmonary nodule(P<0.05).Conclusion The pathology of pulmonary nodule was an important influence factor for SUV of 18F-FLT,and the ~SF-FLT PET/CT has the high diagnostic effectiveness for pulmonary nodules and this method will has great influence on the clinical management of pulmonary nodule patients.

Totally 1136 individuals aged over 40 underwent health check up in March to May 2009. Fasting blood glucose, 2-h post-challenge blood glucose, glycated hemoglobin A1c ( HbA1c), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and serum uric acid were measured. The diagnosis of metabolic syndrome was based on the International Diabetes Federation Criteria. The results shows that total body fat, region body fat indices, blood pressure, blood glucose and serum uric acid levels increased with the age ( P < 0.01) . The prevalence rate of metabolic syndrome in this group of individuals were 15. 1% (171/1136) , and increased with age (P<0.01). The most common combination of metabolic syndrome was central obesity-hypertension-dyslipidemia (40. 9% , 70/171). Unconditional logistic regression revealed that waist-hip-ratio, body mass index and uric acid were the risk factors for metabolic syndrome.
