【Objective】To observe the therapeutic effect of Qi-strengthening and yin-nourishing,stasis-removing and regeneration-promoting therapy for clinical diabetic nephropathy(CDN)and to explore its mechanism.【Methods】Eighty CDN patients with Qi-yin deficiency and stasis blocking kidney collaterals were randomized into groups A and B at the proportion of 3∶1 by using random number table.Group B(n=20)was given routine western treatment involving decreasing blood glucose,blood pressure and blood lipid,taking good quality diet with low protein,regulating water-electrolyte disturbance and acid-base balance,and preventing and curing complicated infection.Group A(n=60)was treated with Qi-strengthening and yin-nourishing,stasis-removing and regeneration-promoting herbal medicine(mainly composed of Radix Astragali,Fructus Mori,Radix Scrophulariae,Radix Angelicae Sinensis,Radix Salviae Miltiorrhizae,Radix et Rhizoma Rhei,Stigma Maydis and Rhizoma Chuanxiong).After treatment,the therapeutic effect was compared in the two groups.Meanwhile,the changes of fasting blood glucose,renal kidney,24-hour urinary protein,blood rheology,blood lipid and fibrinogen(FIB),as well as plasma endothelin 1(ET-1),tumor necrosis factor ?(TNF-?)and interleukin 1(IL-1)were observed.【Results】Qi-strengthening and yin-nourishing,stasis-removing and regeneration-promoting herbal medicine relieved the symptoms and signs of the patients,decreased 24-hour urinary protein content,and improved the renal function parameters in renal compensatory and decompensatory stages.The herbal medicine could also decrease blood lipid and fasting blood glucose levels,improve blood rheology indexes,and decrease serum IL-1 and ET-1 levels(P

BACKGROUND:Up to date,whether prosthesis can be implanted simultaneously with the residue of polyacryamide hydrogel (PAMHG) in the breasts still not consistent. OBJECTIVE:To explore the feasibility and long-term curative effect of prosthesis implanted simultaneously with the residue of PAMHG in the breasts. DESIGN,TIME AND SETTING:The clinical cases analysis was performed at the Department of Plastic and Aesthetic Surgery,No.1 People's Hospital of Nanning were collected. PARTICIPANTS:Totally 23 cases,aged 22-42 years,who received silicone gel breast implant (SBI,100-400 mL) were collected. The time from injection to hospital visit was 0.4-4.5 years. METHOD:PAMHG was cleared as possible,followed by implanted 200-260 mL SBI was via retro-mammary space or sub-pectoral space when cases without inflammation reaction. MAIN OUTCOME MEASURES:The wound healing,regression of breast induration,as well as complication and long-term curative effect was followed up. RESULT:The 0.3-3 years follow-up showed that the whole PAMHG was cleared in 7 cases,a majority of PAMHG was cleared in 8 patients,and partially PAMHG was remained in ectopectoralis of 8 patients. All the breasts of the patients were good at exterior. No obvious nodules,infection,ulcer or gel migration occurred. All patients were satisfied with the surgical results. CONCLUSION:It is feasible and safe to implant prosthesis simultaneously with minimal residue of PAMHG if there is no inflammatory reaction.

Objective To observe the effect of Niaodu Qing Capsule(NQC) and its separated prescriptions on renal transforming growth factor ?1(TGF-?1)mRNA expression in rats with chronic renal failure(CRF).Methods SD rat models of CRF were induced by 5/6 nephrectomy,and then the CRF rats were randomized into model group,Huangqi(Radix Astragali,1.5 g?kg-1?d-1) group,Danshen(Radix Salviae Miltiorrhizae,1 g?kg-1?d-1) group,Dahuang(Radix et Rhizoma Rhei,1 g?kg-1?d-1) group,Huangqi Danshen Dahuang(1 g?kg-1?d-1) group,NQC group(1 g?kg-1?d-1).Except the model group,the rats in other groups received gastric gavage of corresponding medicine according to the experimental design.After treatment for six weeks,the levels of blood urea nitrogen(BUN) and serum creatinine(SCr) were detected,and the expression level of renal TGF-?1 mRNA was examined by reverse transcription polymerase chain reaction(RT-PCR).Results The levels of BUN and SCr were decreased in the medicated groups(P

Fasting plasma preptin level was assayed by RIA in the patients with different glucose tolerances. Regarding fasting plasma preptin levels, it was higher in females than in males. Fasting plasma preptin level was increased in patients with type 2 diabetes as compared with subjects of impaired glucose tolerance and normal controls, and there were positive correlations with diastolic blood pressure, blood triglyceride, total cholesterol, high-density lipoprotein-cholesterol, free fatty acids, 2 h plasma glucose after glucose load, HbA1C and HOMA-IR, suggesting a potential link between preptin and glucose-lipid metabolism and insulin resistance.

OBJECTIVE: To observe the effect of triamcinolone combined with vitamin E on preventing fibrous capsule contracture following the second breast augmentation. METHODS: Totally 65 patients who had 130 breasts receiving the second breast augmentation at the Department of Plastic and Aesthetic Surgery, No.1 People's Hospital of Nanning were collected and served as the treatment group, including 47 cases with capsules contracture and 18 cases with hydrogel clearing. Tri-Kort was injected after the second breasts augmentation, and vitamin E was taken orally for 3 months. Additional 65 cases with 130 breasts received the second breast augmentation were served as control group. The follow-up was performed after half month, and the curative effect was evaluated by Baker grading at 1 year after operation. RESULTS: All cases in the two groups were received 6-24 months follow-up. Only 3 cases (5 breasts) in 65 patients (130 breasts) in the treatment group had capsule contracture (Baker II-III), with 3.8% of capsule contracture, which was obviously less than 18% of capsule contracture in the control group (P < 0.01,13 cases with 23 breasts in the control group). Simultaneously, no drug adverse reaction occurred in the treatment group. CONCLUSION: Triamcinolone combined with vitamin E can obviously depress the rate of capsule contracture after the second breast implantation.

[Objective] To observe the effect of Xiangdan injection with the actions of activating blood and removing stasis for the treatment of acute tubular necrosis (ATN) after kidney transplantation. [Methods] Twenty-six patients with ATN after kidney transplantation were randomized into groups A and B. The two groups were treated with triple immuno-suppressive agents of cyclosporin A, prednisone and mycophenolic acid, with medicines for protecting liver function and gastric mucosa, and with preventive measures from infection. Additionally, group A (n = 16) was treated with Xiangdan injection, while group B ( n = 10) was not. After treatment, time for hemodialysis, renal function and renal flow resistance index of the transplanted kidney were compared between the two groups after the occurrence of ATN. [Results] Compared with group B, time for hemodialysis was shortened, the decrease of serum creatine (SCr) in the transplanted kidney quickened, and renal flow resistance index (RI) of the transplanted kidney decreased (P 0.05). [Conclusion] Xiangdan injection with the actions of activating blood and removing stasis can promote the early recovery of ATN after kidney transplantation.

Objective To investigate urine adiponectin changes and related factors in different stage of type-2 diabetic ne-phropathy.Methods A total of 1 1 9 DN patients admitted to the Yongchuan Hospital of Chongqing Medical University in 2013 were selected.The general indices and laboratory examination results were retrospectively analyzed.1 1 9 type-2 diabetic nephropathy patients were divided into normal Proteinuria group,micro-Proteinuria group,macro-Proteinuria group,according to urine albumin excretion rate in 24 hours.45 health subjects from Physical examination center were enrolled as normal group.The UAER of the three groups were compared and the correlation between each index and UAER was analyzed.Results Urine adiponectin levels in normal Proteinuria group was significantly lower than micro-Proteinuria group(P <0.01)and macro-Proteinuria group(P <0.01). Urine adiponectin levels in micro-Proteinuria group was significantly lower than macro-Proteinuria group (P <0.01)and higher than normal group(P < 0.01 ).Urine adiponectin levels in macro-Proteinuria group were significantly higher than normal group (P <0.01 ).Multiple linear regression analysis showed that HDL-C,FPG,HbA1c and UAER had effects on the levels of Urine adiponec-tin.Conclusion Urinary adiponectin levels are associated with type 2 diabetic nephropathy,and which was related with HDL-C, FPG,HbA1c and UAER.

Objective To observe the effect of tanshinone ⅡA on renal transforming growth factor beta 1 (TGF-β1) and nuclear factor-kappa B (NF-κB) p65 mRNA and protein expression in diabetic nephropathy (DN) rats, thus to evaluate the therapeutic effect and mechanism of tanshinone ⅡA. Methods SD rats were used as the experimental animal. DN rat model was induced with 40 mg/kg of streptozocin ( STZ) . The rats were randomized into normal group, model group, and tanshinone ⅡA ( 10 mg·kg -1·d -1, im) group. On the experimental day 30, we examined the body weight, water in-take volume, 24-hour urine protein, fasting glucose ( Glu) , serum creatinine ( Cr) , blood urea nitrogen ( BUN) , total protein ( TP) and albumin ( Alb). Renal slices after periodic acid Schiff staining ( PAS) were used for the observation of renal pathology. Semi-quantitative reverse transcription polymerase chain reaction ( RT-PCR) was used for the detection of renal TGF-β1 and NF-κB p65 mRNA expression, and Western blotting method was used for the measurement of TGF-β1 and NF-κB p65 protein expression in rats of different groups. Results Compared with the normal group, body weight was decreased, water in-take volume and 24-hour urine protein were increased, serum Glu, Cr, and BUN levels were elevated, TP and Alb levels were decreased, renal pathological damage occurred, and renal TGF-β1 and NF-κB p65 mRNA and protein expressin were promoted in the model group (P<0.05 or P<0.01). Tanshinone ⅡA group had an effect on decreasing water in-take volume, 24-hour urine protein, serum levels of Glu, Cr and Bun, increasing TP and Alb levels, relieving renal pathological damage, and reducing the protein and mRNA expression of renal TGF-β1 and NF-κB p65 ( P<0.05 or P<0.01 compared with the model group). Conclusion Tanshinone ⅡA has protective effect on kidney probably through inhibiting renal TGF-β1 and NF-κB p65 expression in DN rats.
