Objective To study the clinical characteristic and treatment of colorectal cavernous angioma and laparoscopic proctosigmoidectomy in colorectal cavernous angioma. Methods Clinical data of 8 colorectal cavernous angioma cases were analyzed. Results Cavernous hemangioma located in the rectum in 4 cases,in the proctosigmoid in 3 cases,and in the proctosigmoid and descending colon in one case.Under definite diagnosis,all cases underwent laparoscopic colorectomy,the postoperative recovery was satisfactory,and there was no postoperative mortality. Conclusions Colorectal cavernous angioma is rare,and usually be misdiagnosed.It commonly involves sigmoid and rectum.Laparoscopic proctosigmoidectomy is an effective way to deal with the disease.

OBJECTIVETo develop a method for determining epichlorohydrin in the workplace air by gas chromatograph-electron capture detector (GC-ECD).
METHODSEpichlorohydrin in the workplace air was collected by activated charcoal tubes, desorbed using acetone, and analyzed by GC-ECD.
RESULTSA good linearity was obtained in the range of 1.0-50 µg/mL (r=0.999 7). The detection limit was 0.012 µg/ml, while the recovery rate was 88.1% and relative standard deviation ranged from 1.11% to 3.57%. The samples could be stored for seven days at room temperature.
CONCLUSIONThis method effectively eliminates the interferences of alkanes on determination of epichlorohydrin and improves the sensitivity by 1 to 2 orders of magnitude, which can solve the problem of detection limit above standard in GBZ/T 160.58-2004.

Objective To investigate the mechanism of grow-inhibition and apoptosis induced by marine on Hep-2 line. Methods The growth inhibiting rate of matrine on Hep-2 cells was detected by MTT assay. Fluorescence microscope, DNA gel electrophoresis and flow cytometry (FCM) were applied to determine the presence of apoptosis and cell cycle. Results Matrine had cytotoxic effect to Hep-2 cells in a time- and dose-dependent manner. The FCM analysis showed that the number of Hep-2 cells of S phase and the apoptosis rate increased, while the number of G2/M phase decreased. There were morphological changes including chromatin condensation, nuclear fragmentation and apeptotic bodies formed. DNA gel electrophoresis analysis showed typical DNA ladder of apoptosis. Conclusion Matrine inhibits cell prolif-eration by blocking Hep-2 cell cycle to S phase, and exerts its anti-carcinoma function by inducing apoptosis.

Objective To observe the anatomical and functional changes in patients with different degrees of myopic traction maculopathy (MTM) after vitrectomy.Methods It was a retrospective case series study.Forty-seven consecutive patients (47 eyes) diagnosed with MTM were studied between January 2010 and May 2014.There were 38 females (38 eyes) and 9 male (9 eyes),mean age was (65.13±6.98) years,mean axial length was (29.23±1.77) mm.The eyes was divided into 3 groups according to the macular morphologies on optical coherence tomography (OCT),including macular retinoschisis only group (MRS group,18 eyes),foveal retinal detachment group (FD group,13 eyes) and full-thickness macular hole group (MH group,16 eyes).All the eyes underwent minimum resolution angle in logarithmic (logMAR) best corrected visual acuity (BCVA),intraocular pressure,axial length,A or B-ultrasonography,fundus photography,OCT and microperimetry examinations.The average logMAR BCVA of 47 eyes was 1.43±0.52.The center retinal thickness (CRT) of eyes in MRS and FD group was (528.45± 167.61) μm.All the patients underwent pars plana vitrectomy combined with internal limiting membrane peeling.The mean follow-up period was 23.4 months.The changes of logMAR BCVA,microperimetry and macular microstructural were observed.Results At the final follow-up,the logMAR BCVA of 47 eyes was 0.86 ± 0.42,which improved compared with the preoperative vision (t=7.36,P< 0.001).The mean CRT of eyes in MRS and FD group was (250.90 ± 91.81) μm,which improved compared with the preoperative CRT (t=8.17,P<0.001).In MRS group,the retina was attached in 18 eyes.In FD group,the retina was attached in 11 eyes,MH was observed in 2 eyes.In MH group,recurrent retinal detachment was observed in 1 eye.The differences of logMAR BCVA and retinal sensitivity among MRS,FD and MH groups were significant (x2 =6.38,11.08;P=0.030,0.004).Conclusion The macular structural and visual function in MTM eyes with macular retinoschisis only after vitrectomy are better than those in MTM eyes with MH and foveal retinal detachment.

Follicle-stimulating hormone (FSH) is synthesized and secreted by the anterior pituitary, which binds to its receptors expressed on the membrane of Sertoli cells in the testis to bring about spermatogenesis. With the development of DNA sequencing technology, FSH SNPs rs10835638 and FSHR SNPs rs6165, rs6166, and rs1394205 were detected, which might directly affect the expression of FSH and activity of FSHR, resulting in male spermatogenic dysfunction. This review focuses on the relationship of FSH and FSHR gene polymorphisms with male infertility.

OBJECTIVETo explore the detoxication and tissue generation effect of Astragalus (As) in wound healing and its relation with inflammatory reaction, through observing the effect of Astragalus polysaccharides (AP) on neutrophil-endothelial cell adhesion and expression of related adhesive molecules.
METHODSHuman polymorphonuclear leucocyte (PMN) or human umbilical vein endothelial cell (HUVEC) was treated separately with AP, AP plus interleukin 1 (IL-1) and tumor necrosis factor (TNF) to study the effect of AP on PMN adhesion with HUVEC by rose bengal staining, and that on expression of superficial adhesive factor by means of Cell-ELISA and APAAP method.
RESULTSWhen AP acted on HUVEC, it could significantly promote the adhesion of HUVEC with PMN, while when AP acted on PMN, the adhesion would not increase. When HUVEC was treated by AP plus IL-1, the IL-1 induced PMN adhesion with HUVEC could be strengthened, and the expression of HUVEC superficial adhesive factor ICAM-1 induced by IL-1 and TNF was strengthened also, but when PMN treated with AP, it showed no effect on the expression of adhesive factor CD18.
CONCLUSIONAP promotes the adhesion between neutrophil and endothelial cell by way of promoting the expression of superficial I-CAM-1 on surface of endothelial cells, so as to improve the inflammatory reaction in the wound healing course, it possibly is one of the biological bases of the detoxication and tissue generation effects of AP.

Objective To explore the effects of Sishen Pill and Gegen Qinlian Tablet on cytokines of acute and chronic colitis induced by dextran sulfate sodium (DSS) in mice. Methods Mice freely drank 4%DSS dissolved in drinking water for continuous 5 days to establish acute colitis model. Mice circularly drank 3% DSS for 4 times for the establishment of chronic colitis model. In the acute or chronic colitis experiment, mice were randomly divided into control group, acute and chronic model groups, Sishen Pill group, and Gegen Qinlian Tablet group. Acute model group was administrated one day after DSS drinking for 8 days. Chronic model group was administrated after the second time of circular drinking for 16 days. ELISA was used to detect the contents of IFN-γ, IL-17 and IL-22 in cultural supernatant of mouse colon. Results Contents of IFN-γ, IL-17A and IL-22 in cultural supernatant increased significantly in acute models (P<0.01). Gegen Qinlian Tablet can significantly decrease the contents of IFN-γ and IL-17A of acute models (P<0.05). Sishen Pill can significantly decrease the content of IL-17A (P<0.05). IFN-γand IL-17A in cultural supernatant in chronic model mice significantly increased compared with control group (P<0.01). Sishen Pill and Gegen Qinlian Tablet inhibited the contents of IFN-γ and IL-17A. Compared with control group, Sishen Pill significantly increased the content of IL-22 (P<0.05). Conclusion Sishen Pill and Gegen Qinlian Tablet can treat colitis by decreasing the contents of IFN-γ and IL-17A in acute colitis model mice;Sishen Pill can treat chronic colitis by promoting IL-22 to increase.
