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 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.

OBJECTIVETo investigate the association of A260G and A386G polymorphisms of the DAZL gene with male infertility caused by oligozoospermia or azoospermia.

METHODSWe searched the PubMed, Science Direct, Wiley Online Library, CNKI, VIP, and CDDB databases up to November 30, 2013 for case-control studies evaluating the relationship of SNP260 and SNP386 polymorphisms of the DAZL gene with male infertility, and meanwhile conducted manual sourcing of the references in the identified studies and relevant articles. Two reviewers independently screened the title, abstract and keywords of each article retrieved. The StataSE12. 0 software was used for meta-analysis and other statistical analyses.

RESULTSTotally, 13 case-control studies were included (10 about A260G and 11 about A386G), involving 2 715 infertile patients (2 500 with oligozoospermia or azoospermia) and 1 835 normozoospermic men. DAZL A260G showed no statistical significance in the allele, dominant, recessive, co-dominant, or super-dominant gene model (P >0. 05). DAZL A386G exhibited a strong correlation with oligozoospermia or azoospermia in Asians in the allele gene model (OR = 0. 15, 95% CI 0.07 -0.34, P <0.05), dominant gene model (OR =0. 16, 95% CI 0.07 - 0. 35, P <0.05), co-dominant gene model (AA/AG) (OR = 0. 15, 95% CI 0. 06 - 0. 33, P < 0. 05), and super-dominant gene model (OR = 0. 15 (95% CI 0.06 - 0.33, P <0.05) , and so did it in Chinese in the four gene models ( OR = 0. 11, 95% CI 0.04 - 0. 28, P <0.05; OR =0. 11, 95% CI 0.04 - 0.28, P<0.05; OR = 0.09, 95% CI 0.03 - 0.26, P<0.05; OR = 0.09, 95% CI 0.03 - 0.26, P< 0.05).

CONCLUSIONOur study manifested that the DAZL polymorphism A386G, but not A260G, was correlated with reduced sper- matogenesis or sperm count specifically in Chinese males. More high-quality trials are required for a deeper insight into the exact relationship of DAZL A260G and A386G polymorphisms with oligozoospermia- or azoospermia-induced male infertility.

Objective To study the effect of sevoflurane pretreatment or aftertreatment on intrapulmonary shunt for patients with one lung ventilation(OLV)during thoracic surgical procedures .Methods 80 ASA I or II patients underwent thoracic surgery with OLV were randomly divided into four groups(n= 20 for each):(1)Propofol group(group P);(2)Sevoflurane pretreatment group(group S1);(3)Sevoflurane aftertreatment group(group S2);(3)Sevoflurane whole-treatment group(group S3) .Blood sam-ples were taken from radial artery and right atrial blood before induction of anesthesia(baseline T .0) ,before OLV(sevoflurane pre-treatment 30 min ,T1) ,after OLV 30 ,60 min and before the end of OLV(T2-T4)and after the end of OLV(T5)for measurement of blood gases and calculation of Qs/Qt .The indexs of hemodynamics and relative clinical data were recorded .Results Arterial oxy-gen pressure of the four groups for OLV significantly reduced ,when compared with double lung ventilation(P<0 .05) ,but there was no significant difference among the four groups(P>0 .05) .Intrapulmonary shunt of the four groups for OLV significantly in-creased ,when compared with double lung ventilation(P<0 .05) ,but intrapulmonary shunt of S1 ,S2 and S3 groups significantly de-creased ,when compared with P group ,and there was no significant difference for S1 ,S2 and S3 groups(P> 0 .05) .Conclusion Sevoflurane can decrease intrapulmonary shunt for patients during OLV ,but there is no significant difference for pretreatment or af-tertreatment or whole treatment and do not increase arterial oxygen pressure .

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.
