Objective To study the incidence of complications of visceral and vascular injury in laparoscopic surgery for gynecologic diseases,and to discuss the ways to decrease the incidence. Methods The data of 2684 patients who received laparoscopic surgery from Januray 2003 to December 2005 in the Department of Obstetrics and Gynecology were reviewed retrospectively.The incidence and treatment of complications of visceral and vascular injury were observed. Results The total incidence rate of complications was 2.53%(n=68),and that of the visceral and vascular injury was 0.37%(n=10).Four cases of injury were related with trocar punctures(injury of omental blood vessel,n=2;postperitoneal vessel,n=2),three took place during the operation (severe bleeding,n=1;bladder injury,n=2),and the other three were observed in the postoperative stage(ureter injury,n=2;intestinal fistula,n=1). Conclusion The complications in laparoscopic surgery for gynecologic diseases are increased with the extension and difficulty of operation,and are closely related with the experience of the surgeons.Proper candidates for the surgery and established operative technique are the key factors in decreasing the incidence.

Objective To investigate the change of serum insulin like growth factor Ⅰ (IGF Ⅰ) level in newly diagnosed senile patients with type 2 diabetes mellitus (DM) before and after regular insulin (RI) therapy. Methods Body mass index, blood pressure (BP), 24 hour urinary microalbumin (24hUAlb), fasting blood glucose (FBG), 2 hour postprandial blood glucose (P2hBG), serum insulin (Ins) and C peptide (C P), HbA 1c and IGF Ⅰ were measured in 60 senile type 2 DM patients newly diagnosed by oral glucose tolerance test (OGTT) and 40 healthy senile subject (controls); RI 8 U, 6 U, 6 U were injected to type 2 DM patients before three meals respectively. Two days later, above tests were repeated. Insulin resistance index (IR) was calculated. Results The serum IGF Ⅰ levels were (349.0?49.5)?g/L in control group, (231.8?64.4)?g/L and (294.2?46.2)?g/L in patient group before and after RI therapy, The IGF Ⅰ level was significantly lower before RI therapy than that of controls (P

Objective To study the anti-tumor effects of griseofulvin on human prostate cancer PC-3 cells both in vitro and in vivo. Methods PC-3 cells were treated with griseofulvin at various concentrations for48 h,cell survival rate was then measured by MTT assay.The changes of morphology were observed by fluorescence microscope; Annexin V-FITC apoptosis detection kit was used to detect apoptosis of the cells ; The enzyme activity changes of caspase-3,8,9 were detected by spectrophotometry.For in vivo study,we first established the PC-3 tumor model by grafting PC-3 cells in athymic nude mice,and then injected griseofulvin into the tumors.12 days after injection,the mice were sacrificed,the tumors were removed,weighed and the ratios of tumor-suppression were then calculated.We had detected the expressions of Bcl-2,Bax,p53 and Survivin with immumohistochemistry as well. Results MTT results showed that griseofulvin could significantly inhibit the proliferation of PC-3 cells in vitro in a dose-dependent manner,and the IC50 of griseofulvin was 18.17 ±2.10 μg/ml.Typical morphological changes of PC-3 cells were observed by microscope.The rates of apoptosis of griseofulvin treated PC-3 cells greatly increased compared with that of the control cells (31.37 ± 2.93％ vs 2.89 ± 0.67％,P ＜ 0.01 ).The caspase-3,caspase-8 and caspase-9 activities in griseofulvin treated PC-3 cells were significantly higher than those in control cells (0.562 ±0.050 vs0.113±0.014,0.337±0.053 vs 0.120±0.017,0.293±0.038 vs0.109±0.018,P＜0.01).On the 23th day after tumor vaccination,the tumor volume was 961.17 ± 78.12 mm3 in griseofulvin treated group and was 433.6 ± 12.8 mm3 in control group (P ＜ 0.01 ).The tumor weight was 742.50 ± 78.63 mg in griseofulvin treated group and was 1387.33 ± 71.47 mg3 in control group ( P ＜ 0.01 ).Bcl-2,Bax,p53 and Survivin protein expressions were 16.10 ± 3.45％,39.50 ± 6.88％,48.20 ± 8.04％,16.50 ± 2.22％ in griseofulvin treated group,respectively; 41.30 ± 3.95％,13.70 ± 2.98％,17.60 ± 3.21％,52.11 ± 6.28％ in control group,respectively.And there were significant differences in both groups (P ＜ 0.01 ).The in vivo data showed that griseofulvin suppressed the tumor growth conspicuously through down-regulating the expression of Bcl-2,Survivin,and up-regulating the expression of Bax,p53. Conclusions Griseofulvin can inhibit the growth of PC-3 and induce apoptosis of PC-3 cells.Griseofulvin inhibits the in vivo tumorigenicity of PC-3 cells.

OBJECTIVE To analyze the convenient and effective disinfection methods for the carrier vehicles in the hospital supply division.METHODS The spraying disinfection and the traditional disinfection method were used to disinfect carrier vehicles after using,and the samples of main 4 parts of the carrier vehicles were collected for bacterial culture.RESULTS The difference of bacterial counts was significant between before and after disinfection by the two methods(P

Objective To explore the expression and the role of Toll-like receptor(TLR3 and TLR4) in rats with nephrotic syndrome induced by respiratory syncytial virus(RSV).Methods SD rats were inoculated intranasally and intraperitoneally with 6?106 plaque for-ming unit(PFU) RSV to construct RSV-induced nephropathy in rat model.Rats were anesthetized and blood was withdrawn from cardiac on day 4,14,30,60 after inoculation.The normal ones without intervention were set as control group.The renal histology was observed by light microscope and electron microscope.The urinary protein collected in 24 hours were measured.Meanwhile,the expressions of TLR3 and TLR4 were detected by indirect immunofluorescence staining and flow cytometry in peripheral blood mononuclear cells of rats.The results were analyzed by SPSS 13.0 softwore.Results After inoculation,the proteinuria increased and under the electron microscope the foot processes of glomerular epithelial cells were fused which resembled human minimal change nephrotic syndrome.Proteinuria reached the peak and the fusion of foot processes were most extensive in rats of RSV at 60 d.The expressions of TLR3 and TLR4 in each group of RSV-induced nephropathy in rat models were significantly higher than those in normal control group(Pa0.05).Conclusions TLR3 and TLR4 in peripheral blood mononuclear cells of RSV-induced nephropathy rat mo-dels had being significantly activated until 60 d after RSV inoculation.TLR signaling pathway may play an important role in nephrotic syndrome of rats induced by RSV.

Objective To investigate the carotid atherosclerosis(AS) in hemodialysis(HD) patients.Methods Clinical index was measured and intma-media thickness(IMT) of extracranial common carotid artery and presence of atherosclerotic plaques were determined by high-resolution B-mode ultrasonography.Results The age,disease duration,HD duration,triglyceride(TG),low density lipoprotein(LDL),serum C-reactive protein(CRP),mean carotid artery IMT in HD with atherosclerotic plaque were significantly higher than HD without atherosclerotic plaque patients,however,the serum albumin(Alb) was significantly decreased.Mean carotid artery IMT is related to the disease duration,Alb,TG,LDL,CRP in HD patients.Conclusion The CRP,mean carotid artery IMT were increased in HD with atherosclerotic plaque.Mean carotid artery IMT is related to the disease duration,Alb,TG,LDL,CRP in HD patients.To improve malnutrition and decrease micro-inflammation,serum lipid might reduce the rate of AS in HD.

The DNA fragment RM07 was isolated from halophilic archaea Halobacterium halobium, which can function as promoter not only in halophilic archaea, but also in Escherichia coli as eubacterial promoter. Sequencing analysis indicated that it possessed the typical consensus sequences (-35 and -10) of bacterial gene promoter, which was confirmed by further deletion analysis: With its -35 sequence deleted and -10 sequence left,DNA fragment RM07a nearly cannot initiate transcription;With its both -35 and -10 sequences,RM07b DNA fragment could be active as promoter at a level even higher than RM07. Our research also showed that the promoter function of RM07 fragment in Escherichia coli was under the control of environmental factors,especially its positive correlation with the increasing concentration of sodium chloride. Therefore, RM07 DNA fragment may be potential1 novel promoter source for constructing double-function vectors. It also has special significance in elucidating the issues of the fusing characteristics of archaea and lateral gene transfer between archaea and bacteria.
