Objective To evaluate the feasibility of retroperitoneal laparoscopic adrenalectomy for large (≥6 cm in diameter) adrenal tumors. Methods Between June 2002 and June 2008,30 patients with large adrenal tumors underwent retroperitoneal laparoscopic adrenalectomy in our hospital. With the patients being placed in the lateral position at the uninjured side,a self-made balloon was used to dilate the retroperitoneal space. Afterwards,3 trocars were inserted via the costal margin at the posterior axillary line and the anterior axillary line,and 2 cm above the anterior superior iliac spine at the middle axillary line to remove the tumors. After resection of the tumor,an drainage tube was indwelled. Results Retroperitoneal laparoscopic surgery was performed successfully in the 30 cases without conversion to open surgery. The mean operation time was 100 min (range,65 to 185 min),and the mean blood loss was 80 ml (range,50 to 250 ml). Over a mean of 18.5-month follow-up (range,3 to 36 months) was achieved in the cases,during which no one had local recurrence. Conclusions Retroperitoneal laparoscopic adrenalectomy is feasible and safe for patients with large adrenal tumors as long as no contraindication of the surgery is found. The diameter of the tumor does not play a role when determining the surgery.

Objective To study the effect of continous subcutaneous insulin infusion (CSII) and mutiple subcutaneous insulin infusion (MSII) on type 2 diabetes mellitus during perioperation. Methods One hundred and eighty surgical patients complicated with Type 2 diabetes were randomly divided into two groups,98 cases in the CSII group (treated with CSII of novolin R) and 82 cases in the MSII group (treated with MSII of novolin R and no-volin N). Blood glucose level,the time to reach normal blood glucose level, the average dosage of insulin, the inci-dence of hypoglycemic,infection rate of incisions and inpatient days were measured in two groups before and after treatment. Results The level of fasting blood glucose after treatment in the CSII group (4.8 mmol/L (SD: 1.6)) was significantly lower than that of the MSII group (6.4 mmol/L(SD :2.1)) (t = 7.74,P < 0.05), and 2-h glucose in the CSII group (7.6 mmol/L(SD :2.3)) was significantly lower than that of the MSII group (9.3 mmol/L(SD: 2.4)) (t = 7.72, P < 0.05). The time to reach normal blood glucose level in the CSII group (4.1 days (SD: 2.9)) was shorter than that of MSII group (6.9 days (SD :2.0)) (t=2.81, P < 0.05). The average dosage of insulin in the CSII group (40.7 U(SD: 10.3)) was lower than that of the MSII group (63.2 U (SD: 17.0)) (t=3.57, P <0.05). The incidence of hypoglycemic in the CSII group (3.05%) was lower than that of the MSII group (9.20%) (χ~2 = 4.92,P < 0.05). The infection rate of incisions in the CSII group (0.0%) was lower than that of the MSII group (10.9%) (χ~2 =4.18, P < 0.05). The inpatient days in the CSII group (15.3 days (SD :7.2)) was shorter than that of the MSII group (22.5 days (SD :9.7)) (t = 3.12, P < 0.05). Conclusions Compared to multiple sub-cutaneous insulin infusion, continuous subcutaneous insulin infusion is more effective in controlling blood glucose, hypoglycemic and incision infection, thus is recommend to perioperative patients complicated with type 2 diabetes mellitus.

ObjectiveTo investigate the protective effect of combination of triptolide and irbesartan on the podocytes in a type 2 diabetic(T2DM) rat model,and evaluate its mechanism.Methods T2DM rats were induced by fed with high-sucrose-high-fat diet combined with a low dose of streptozocin.The rats were randomly divided into 5 groups:normal control group ( NC,n =10),diabetes group ( DM,n =11),triptolide treatment group (DT,n =12),irbesartan treatment group (DI,n =12) and triptolide combined with irbesartan treatment group (DTI,n =13). Ultrastructure of podocytes was observed by electronic microscopy and urinary albumin (UAL) excretion by ELISA was determined after 8 weeks.The expression of nephrin and bone morphogenetic protein-7(BMP-7), connective tissue growth factor (CTGF),transforming growth factor (TGF)β1 mRNA and proteins were detected by immunohistochemistry,real-time PCR and Western blot. Results Increased UAL was significantly attenuated in all treatment groups.Compared to NC group,UAL in DM group was increased significantly (0.45 ± 0.09 vs 6.36 ± 0.87,P < 0.01 ),while decreased in triptolide or irbesartan alone treatment group (2.48 ± 0.37 and 2.68 ±0.42,both P < 0.01 ).Compared with those in control groups,kidney expression of nephrin,BMP-7 mRNA and proteins were downregulated while CTGF, TGFβ1 mRNA and proteins were significantly upregulated in T2DM rats. Triptolide or irbesartan each alone moderately ameliorated albuminuria and podocyte damage.However,their combined usage showed a dramatic therapeutic synergism,manifested by prevention of progressive albuminuria,restoration of the glomerular filtration barrier,reversal of the decline in slit diaphragm proteins,reduction expression of CTGF,TGFβ1,and upregulation of BMP-7.Conclusion Our findings show that triptolide can increase the efficacy of irbesartan,leading to a more effective prevention of kidney disease in T2DM rat model,which may through upregulation of BMP-7 and inhibition the overexpression of CTGF and TGFβ1.

BACKGROUND: High-concentration glucose can induce the formation of biofilms in Staphylococcus epidermidis.OBJECTIVE: To investigate the effect of high-concentration glucose on eliminating ability and adhesion of Staphylococcus epidermidis in Tupaia belangeri.METHODS: Tupaia belangeri models of hyperglycaemia (≥11.1 mmoL/L) were induced by intraperitoneal injection of Streptozocin. PVC catheters were inserted into the left femoral vein, and Staphylococcus epidermidis with or without formation of biofilms was inoculated into the catheters.RESULTS AND CONCLUSION: Following transfection of Staphylococcus epidermidis with formation of biofilms, there were higher rates of bacterial infection as well as higher bacterium colony number in the serum, heart, liver, kidney and pancreas of Tupai belangeri in hyperglycemia group (≥11.1 mmoL/L) as compared with the control group (P < 0.05). Detected by scanning electronic microscope, biofilm formation was remarkable in hyperglycemia group (≥11.1 mmoL/L) (P < 0.05). However, there was no formation of biofilms in hyperglycemia or control groups following transfection of Staphylococcus epidermidis without formation of biofilms. Hyperglycemia can induce the decreasing ability of eliminating bacteria and the increasing formation of biofilms on the surface of biomaterials transfected with Staphylococcus epidermidis.

Background and purpose: The prognostic factors on survival for the patients with prostate carcinoma are still underdeterrnined. This study was to analyze the survival of three common treatment methods for prostate carcinoma and the prognostic factors on survival. Methods: 494 male patients who were diagnosed as prostate cancer were enrolled into the retrospective study. All of the data like age, stage, grade, PSA level, ALP, Hb and treatments were collected. Overall survival and disease specific survival rates for patients were analyzed by Kaplan-Meier method. Prognostic factors on disease specific survival were also analyzed by Log-rank test and Cox proportional hazards model. Results: Disease specific survival rates at 1, 3 and 5 year were 96.0%, 89.0% and 80.0% for all 494 patients, respectively. Disease specific survival rate at 3-year was 92.4% for brachytherapy, 100.0% for radical prostatectomy and 80.6% for hormonal therapy (P=0.008). Multivariate analysis by Cox model showed that stage, PSA level and age significantly impacted on disease specific survival. Conclusion: Brachytherapy and radical prostatectomy provides longer survival time than hormonal therapy for patients with prostate cancer. Clinical stage and PSA level and age of prostate cancer are independent factors impacting on survival significantly.
