Objective To observe the clinical effect of treating diabetic nephropathy with Shengqidihuang decoction combined with metformin. Methods 54 cases with diabetic nephropathy were randomly divided into two groups by means of random number table. Both groups were given diabetic routine treatment. The control group was treated with metformin, 0.25 mg each time, three times a day, based on the diabetic routine treatment for 8 weeks, and the treatment group was treated with Shengqidihuang decoction, once a day, 4 weeks as a course, continuously treated for 2 courses based on the control group. 24 h urinary protein (24hUAE) , serum creatinine (SCr) , blood urea nitrogen (BUN) and fasting blood glucose (FBG) were detected before and after the treatment. The clinical effect was observed between the two groups after the treatment. Results The total effective rate of the treatment group and the control group was 85.2% and 66.7% respectively, showing a significant difference (λ2=3.376, P<0.05). Compared with the control group, 24 hUA ,SCr, BUN and FBG in the treatment group decreased significantly (λ2=4.231, P<0.05) after the treatment.24hUAE, SCr, BUN and FBG decreased significantly after the treatment, especially in the treatment group, also showing a significant difference (λ2= 3.754, P<0.05). Conclusion The therapy of mefformin combined with Shengqidihuang decoction on diabetic nephropathy was better than metformin only.

Objective To investigate the effect of the gene polymorphism of cholesterol ester transfer protein (CETP) on the serum lipid levels in renal transplant patients.Methods Serum total cholesterol (TC),triglyceride (TG),low density lipoprotein (LDL),high density lipoprotein cholesterol (HDLC),apolipoproteins (Apo A1,B,E) and lipoprotein(a) [Lp(a)] were measured. Polymerase chain reaction-restriction fragment length polymophism (PCR-RFLP) was used to detect CETP gene polymorphism in renal transplant recipients.Results Serum levels of TC,TG,HDLC,LDLC,ApoB,ApoE in the renal transplant recipients were increased significantly after transplantation. The allele frequency and the distribution of the TaqⅠ(intron 1) and MSPⅠ(intron 8) genotypes showed no significant difference between the controls and the renal transplant recipients. The serum TG level was significantly higher in renal transplant recipients with the genotype TaqⅠB1/B1 than those in the patients with genotype TaqⅠ B1/B2 and B2/B2. But there was no statistical difference among the serum lipid levels in renal transplant recipients with different MSPⅠgenotypes.Conclusion The serum lipid levels were increased significantly in transplant after transplantation,and the patients with CETP genotype TaqⅠB1/B1 liable to develop hypertrglyceridemia.

Objective To understand the efficiency of defluoridation facilities used in drinking water defluoridation in the rural high fluoride areas in Tianjin and the sanitary characteristics of treated drinking water. Methods The raw water samples and treated water samples were collected from 4 water stations where the electrodialysis technics was applied and 6 water stations where the reverse osmosis technics was applied and the facilities had been operated for 2-3 years in a county, as well as 3 water stations applied activated aluminium oxide adsorption technics and 2 water stations applied nanofiltration membrane technics in the other counties in Tianjin in 2002-2004. The pH value,turbidity, total dissolved solids, total hardness, fluoride, sulfate, aluminium, in all water samples were determined and evaluated according to the Sanitary Standard for Drinking Water(2001). Results The treated water samples from electrodialysis and reverse osmosis defluoridation facilities showed lower fluoride level(below 1.0 mg/L with fluoride removal rates of 90.01% and 75.32%),and lower total dissolved solids and total hardness levels with removal rates of 75.83%-93.48%. The treated water samples from nanofiltration membrane defluoridation facilities also showed lower fluoride level(below 1.0 mg/L with fluoride removal rates of 75.16%,and lower total dissolved solids and total hardness levels with removal rates of 64.90% and 77.22% respectively. Conclusion The investigated electrodialysis, reverse osmosis and nanofiltration membrane defluoridation facilities show a reliable efficiency and are suitable for application of removal of fluoride in drinking water with different levels of total dissolved solids in the rural high fluoride areas. The effects of defluoridated water produced by reverse osmosis defluoridation facilities on human health need to be studied further more.

Objective To assess the value of intraoperative ultrasonography during the uterus septum resection under a hysteroscope.MethodsThe uterus septum resection was performed under the guidance of transabdominal ultrasonography by using a hysteroscope in 30 patients.The operative procedure and the position of the hysteroscope were monitored,and the depth of the dissection and thickness of the myometrium in the fundus uteri were measured with transabdominal ultrasound during the operation.ResultsThe thickness between the incisal surface and serosal layer in the fundus uteri was within the normal limits in 28 cases.In 2 cases,the tissue was over-ectomized.The position of the urethral catheter balloon was correct in all of the 30 cases.Three months after the procedure,reexamination by transvaginal ultrasonography showed that the uterine cavity was normal in the patients.ConclusionsIntraoperative ultrasonography is quick,safe and precise for monitoring uterus septum resection.It is valuable for establishing surgical strategy and reducing operative complications.
