Objective To investigate the feasibility and efficacy of posterior retroperitoneoscopic adrenalectomy (PRA).Methods From September 2013 to September 2015,the clinical data of 35 patients who underwent posterior retroperitoneoscopic adrenalectomy were reviewed.There were 14 males and 21 females,aged 15-70 years,with the average of 45.8 years.Preoperative CT scan showed 19 adrenal tumors in the left side,16 in the right side,and one case with the left adrenal adenoma combining with right renal cyst.Tumor diameter is between 10 ～ 60mm,with the average of 31mam.Twenty-two cases were diagnosed as primary aldosteronism,4 pheochromocytoma,and 9 non-functional adrenal tumor.The posterior retroperitoneoscopic adrenalectomy were performed in all of the cases,which are under general anesthesia with tracheal intubation and prone position with hip joints and knee joints flexion of 90.Results Thirty-five operations were successfully completed via the posterior approach demonstrating clear anatomical layers.The operation time was 38-138min(mean 70 min),the drainage tube indwelling duration was l-Sd(average 2d),and the hospital stay was 2-6d (average 4d).Total costs of hospitalization were 14 789-31 992 yuan RMB,with an average of 21 239 yuan RMB.No complications occurred during the perioperative period.The average follow-up was 11 months,and no complications such as tumor recurrence occured.Conclusions Retroperitoneoscopic adrenalectomy provided clear anatomical views.It could be a safe and effective operation for the treatment of adrenal tumors.

Objective:To investigate the prognostic value of neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and prognostic nutritional index (PNI) before radiation in pancreatic cancer patients underwent radiation therapy. Methods:Clinical data of 61 patients with pathologically confirmed pancreatic cancer were retrospectirely analyzed. Query index values for each patient were clinically tested through electronic medical records. Overall survival (OS) data were collected through electronic medical records or telephone follow-up. Survival curves were compared using Kaplan-Meier methodology and log-rank test. Cox regression methodolo-gy was used for univariate analysis. Results:Using log-rank test and univariate regression analysis, we found that patients with lower NLR, PLR, CA19-9, increased PNI, and lower TNM-staging lived longer than those with increased NLR, PLR, CA19-9, lower PNI, and high-er TNM-staging, and that the difference was statistically significant. Through multivariate analysis, we found that NLR (P=0.029, OR 2.344, 95%CI:1.090-5.041) and PNI (P=0.026, OR 0.477, 95%CI:0.248-0.917) were independent predictors of OS in patients with pan-creatic cancer. Conclusion:NLR, PLR, and PNI are simple, effective, and reliable indicators for evaluating the prognosis of pancreatic cancer.

Objective:This study was to study effect of keeping ying and weiqi in balance on cardiac muscular collagen Ⅰ,collagen Ⅲ,angiotensinⅡ in spontaneous diabetes rats,and provide new thoughts for prevention and treatment for diabetic cardiomyopathy.Methods:40 spontaneous diabetes rats were divided into four groups at random:spontaneous diabetes control group,diformin group,Guizhi Decoction group and Huanglian Jiedu Decoction group.Except control group,each group was given intragastric administration for 12weeks.Blood glucose,collagenⅠ,collagen Ⅲ,collagenⅠ/collagen Ⅲ,angiotensin Ⅱ were determined.Euzymelinked immunosorbent assay and radio-immuniy method were used.Results:Blood glucose in Huanglian Jiedu Decoction group and diformin group decreased;Compared respectively with diformin group and control group,collagenⅠdecreased obviously and collagen Ⅲ increased signifi cantly in Guizhi Decoction group,and the collagenⅠ/collagen Ⅲ decreased.Compared with diformin group and control group,cardiac muscular homogenate AT-Ⅱ contents decreased in both of Guizhi Decoction group and Huanglian Jiedu Decoction group.Conclusion:Guizhi Decoction can decrease the content of collagen Ⅰ,AT-Ⅱ and collagenⅠ/collagen Ⅲin cardiac muscular,and increase content of collagen Ⅲ,then prevent and treat cardiac muscular collagen reconstruction and myocardial fibrosis.Huanglian Jiedu Decoction can decrease the content of AT-Ⅱ,and decrease collagenⅠ/ collagen Ⅲ,collagenⅠ slightly,and can improve cardiac muscular collagen reconstruction.Keeping ying and weiqi in balance is a new thought for prevention and treatment for diabetic cardiomyopathy.

AIM: To investigate the injuring effect of DMSO-soluble particles from cigarette smoke(DSP) on human umbilical vein endothelial cells. METHODS: Human umbilical vein endothelial cell line EA. hy 926 was used as target cells in the study. The growth and viability of the cells treated with various dosages (1, 2, 4 or 4 mL/L) of DSP and low dose (2 mL/L) of DSP at different time points were evaluated by MTT colorimetric assay and celllular protein assay in 96-well plates. Transmission electron microscopy study was carried out to observe the ultrastructure of human umbilical vein endothelial cells under DSP treatment.RESULTS: DSP inhibited the proliferation of human umbilical vein endothelial cell line EA. hy 926. Under DSP treatment, the reducing cellular protein and increasing cell death(mainly necrosis) were observed in time-dependent and dosage-dependent manners.CONCLUSIONS: These results indicated that the toxic effect of DSP caused functional disturbance and structural damage of human endothelial cells.

Objective To analyze the function of let-7e in the carcinogenesis of non-small-cell lung cancer.Methods The microRNA let-7e expression levels in cancer tissues and adjacent normal lung tissues were detected by quantitative real-time reverse transcription-PCR from 35 non-small-cell lung cancer patients,U6 RNA as an actin.Results The expression of microRNA let-7e in cancer tissues was significantly higher than adjacent normal lung tissues (10.111±6.135,P ＜ 0.0001),there was a significantly different between squamous carcinoma group (9.635±8.300) and adenocarcinoma group (10.301 ±5.228,P ＜ 0.05),independently of sex,smoking history,stage,and histologic characteristics of the tumor.Conclusion The expression of microRNA let-7e in cancerous tissues is high,microRNA let-7e should play oncogene role in process of non-small-cell lung cancer,and would be an useful biomarker.
