Objective To compare the effects of methylprednisolone and dexamethasone individually combined with tropisetron on the prevention of postoperative nausea and vomiting (PONV) of high risk in patients with thyroid surgery.Methods One hundred and sixty patients of high risk of postoperative nausea and vomiting scheduled for radical operation of thyroid with general anesthesia were randomly divided into four groups with 40 cases each.Four groups of the patients were intravenously injected methylprednisolone 40 mg plus tropisetron 5 mg at the end of the operations (group MT),dexamethasone 7.5 mg before anesthesia induction,and tropisetron 5 mg at the end of the operations (group DT),tropisetron 5 mg at the end of the operations (group T),and normal saline (group C).Incidence and severity of nausea,vomiting and adverse reactions were recorded during 24 hours after end of the operations.Results Compared to group DT,the incidences of PONV during the 0 ～ 2 h and 2 ～ 6 h,and the visual analogue scale (VAS) of PONV at 2 h after the operations in group MT were significantly lower (P ＜ 0.05).Compared to group C,the incidences of PONV and VAS score during the 0 ～ 24 h after the operations in group MT and group DT were significantly lower (P ＜0.05),the incidences of PONV during the 2 ～6 h and 6 ～ 12 h after the operations,and VAS score of PONV at 6 h and 12 h after the operations in group T were significantly lower (P ＜0.05).Compared to group C,incidences of headache in group MT and group DT were significantly lower (P ＜ 0.05),and incidence of swim in group T was also significantly lower (P ＜ 0.05).Incidence of adverse reactions in group MT and group DT were no significant difference.Conclusions Preventive effect of methylprednisolone combined with tropisetron for PONV in high-risk patients within 6 hours after thyroid surgery was significantly better than that of dexamethasone combined with tropisetron.

Objective To explore the effect of triperygium wilfordii polyglucoside(TWP) on the podocytes of rats with diabetes nephropathy(DN). Methods One hundred SD rats were randomly divided into normal control group (Group A),DN group (Group B),TWP group(Group C).TWP group was divided into 3 subgroups(Ca,Cb,Cc)according to the different doses 4,8,16mg·kg-1·d-1,respectively.Rats in DN group and TWp group were given streptozocin(STZ)by intraperitoneal injection to establish animal model of diabetes.After 12 weeks,24 h urinary protein excretion rate(UAER),BUN,Scr,white blood cell(WBC),blood glucose(Glu),and kidney weight (KW)/body weight(BW)were determined.The renal pathological changes were evaluated by HE staining.The structural change of podocytes was observed by transmission electron microscope.The expressions of nephrin and podocin were evaluated by immunofluorescence staining. Results (1)Compared to group A,Scr,BUN,Glu,KW/BW,and UAER were significantly higher(P＜0.05)in group B and group C.Whereas the elevated liver enzymes and the decreased WBC were presented in group Cc (3/20). Compared to group A, the protein expressions of nephrin and podocin in nephridial tissue were lower, and the significant differences of pathomorphology in glomerulus,tubules and podocytes were observed in group B and group C. (2) Compared to group B, KW/BW and UAER were lower in group C (P＜0.01); the protein expressions of nephrin and podocin were higher in nephridial tissue; the pathomorphological improvements were exhibited in glomerulus,tubules and podocytes in group C, paralleled with the increase of TWP dose (P＜0.05 or P＜0.01).Conclusions TWP may exert the protective effect on podocytes in diabetic nephropathy rats,dependent on the dose of TWP. The mechanism may be associated with the up-regulatied expressions of nephrin and podocin.

To analyze the causes and treatments of high intraocular pressure ( > 21mmHg ) of angle - closure glaucoma underwent compound trabeculectomy 1mo after surgery.
●METHODS: This was a retrospective study of our hospital, from March 2010 to March 2013. Thirty-four (38 eyes) of angle-closure glaucoma patients were collected, who underwent compound trabeculectomy with high intraocular pressure ( > 21mmHg) 1mo after operation. We analyzed the causes and summarized the treatments.
●RESULTS:The causes which lead to early postoperative high intraocular pressure included malignant glaucoma (9 eyes of 8 cases), blood clot and connective tissue block under the scleral flap (15 eyes of 13 cases), hyphema after surgery(5 eyes of 5 cases), sclera flap incision was incarcerated with iris tissue ( 3 eyes of 3 cases ), preoperative high intraocular pressure for a long time(5 eyes of 4 cases), 1 eye of 1 case for unknown reason. After proper treatments, intraocular pressures of all patients were bellowed 21mmHg.
● CONCLUSlON: Early postoperative high intraocular pressure of angle - closure glaucoma underwent compound trabeculectomy is caused by various factors, and the early prevention and timely treatment are key points of a successful operation.

Objective To investigate the protective effects of lentivirus mediated Bcl-2-associated athanogene 1L (BAG-1L) over-expression on human neuroblastoma cells (SH-SYSY) induced by hypoxia/re-oxygenation,and to study its effect on the phosphoinositide 3 kinase serine/threonine protein kinase (PI3K/AKT) pathway.Methods SH-SYSY cells were cultured in vitro,and the cells at logarithmic phase were collected,and they were divided into recombined lentiviral infection group [infected by lentivirus containing BAG-1L and green fluorescent protein (GFP) gene],vector control group (infected by lentivirus containing GFP without BAG-1L gene) and cell control group (non-infection).Western Blot was used to detect the expression of BAG-1L in target cells after infection for 48 hours.SH-SY5Y cells were subjected to hypoxia for 8 hours and re-oxygenation for 24 hours,then the cell counting kit-8(CCK-8) was used to detect the cell activity,and the apoptosis was detected by flow cytometry after allophycocyanin labeled annexin V/7-amino actinomycin D (Annexin V-APC/7-AAD) staining.Western Blot was used to detect the protein expressions of BAG-1L,heat shock protein 70 (HSP70),AKT and phosphorylated AKT (p-AKT).Results After infection for 48 hours,exogenous BAG-1L protein bands were observed in recombined lentiviral infection group,but not observed in cell control group and vector control group.After hypoxia/re-oxygenation treatment,the cell viability in recombined lentiviral infection group was significantly higher than that in cell control group and vector control group (A value:0.689 ± 0.036 vs.0.425 ± 0.013,0.400 ± 0.012),apoptosis was significantly decreased [apoptosis rate:(26.97 ± 1.82)％ vs.(36.60± 1.45)％,(35.77 ± 3.74)％],the protein levels of BAG-1L,HSP70 and p-AKT were significantly increased [BAG-1L protein (gray value):2.405 ± 0.167 vs.0.529 ± 0.141,0.601 ± 0.099;HSP70protein (gray value):0.997±0.123 vs.0.634±0.091,0.584±0.106;p-AKT protein (gray value):1.234±0.118 vs.0.661 ± 0.210,0.712 ± 0.199,all P ＜ 0.01],but the protein level of AKT was slightly increased (gray value:1.103 ± 0.269vs.0.646 ± 0.188,0.791 ± 0.326) without statistically significant differences (both P ＞ 0.05).There was no significant difference in all parameters between cell control group and vector control group (all P ＞ 0.05).Conclusion Lentivirus mediated BAG-1L gene over-expression can protect nerve cells against hypoxic injury and apoptosis,and the protective effect may be related to the activation increase of pathway on PI3K/AKT.
