Laparoscopic surgery is widely used in the treatment of gynecological malignancies,including the radical surgery or staging surgery of early cervical cancer,endometrial cancer and ovarian cancer.Its feasibility and safety of clinical practice in gynecologic malignancies has been approved,and the postoperative follow-up results indicate that the effectiveness of laparoscopic surgery is similar to open surgery.But the laparoscopic surgery treatment of gynecological malignancies is still in dispute.The research will focus on the affects of pneumoperitoneum to the malignant behavior of tumor cells and the mechanism about implantation metastasis of puncture site in future.

Objective To observe ocular manifestations of acquired immunodeficiency syndrome (AIDS). Methods Fourty-two AIDS patients (66 eyes)with ocular complaints received examinations of visual acuity, slit-lamp microscope, ophthalmoscope and fundus fluorescence angiography (FFA). The results were retrospectively analyzed. ResultsThere are five types of ocular findings, including cytomegalovirus (CMV) retinitis (37 eyes, 56.0%), retinal microvasculopathy of human immunodeficiency virus (21 eyes, 32.0% ), optic nerve diseases (three eyes, 4.5 % ), retinal neuroepithelial layer detachment (two eyes, 3.0%) and uveitis (three eyes, 4.5%). Conclusions The common ocular manifestations showed progressive necrotic retinitis, retinal hemorrhage and retinal vasculitis and attenuated, cotton-wool spots in AIDS patients.

Objective To research nitric oxide( NO) concentration, induced nitric oxide synthase( iNOS) mRNA expression and the pathological changes of lung tissue in traumatic shock rats of early stage preconditioned with heat stress. Methods A total of 98 male SD rats were equally divided randomly into heat stress untreated group and heat stress treatment group, and each group were equally divided into 7 subgroup: control group and shock 0 h group, 0. 5 h group, 1. 0 h group, 1. 5 h group, 2. 0 h group, 3 h group. To established the model of traumatic shock after heat stress pretreatment and remained lung tissue, observed the changes of pulmonary pathology, meas-ured the changes of the NO concentration and iNOS expression in lung tissues. Results The lesions of lung tissue structure were more lighter in heat stress treatment group than the corresponding time point of heat stress untreated group and lung histopathology score lower. The NO concentration of heat stress treatment group were lower than the corresponding time point of heat stress untreated group, the two groups have a rise at shock 0 h,the peak value of NO concentration in heat stress treatment group appeared later than the heat stress untreated group. INOS mRNA expression quantity of heat stress treatment group were lower than the corresponding time point of heat stress un-treated group, the peak value of heat stress untreated group in 2.0 h and heat stress treatment group in 1. 5 h, it was positively correlated with lung injury score. Conclusion Heat stress pretreatment can drop NO concentration and iNOS mRNA expression in lung tissues significantly, delayed and reduced the lung injury in traumatic shock rats of early stage.

Objective: To investigate the relationship of TNF-A-863 and CGRP979 gene polymorphisms with the susceptibility to severe chronic periodontitis in Chinese. Methods: Buccal swabs were collected from 100 adult patients with severe chronic periodontitis and 118 healthy adult controls. DNA was extracted from each subjects of the two groups. PCR-LDR technique was used to identify the genotypes of TNF-A-863 and CGRP979. The difference in the genotypes between the two groups was analyzed by statistics software. Results: The genotype of TNF-A--863 was mainly TNF-A-863 A/C in patients with severe chronic periodontitis and TNF-A-863 C/C in healthy controls. There were significant differences in TNF-A-863 distribution between the two groups( P<0.05). We also found that there were significant differences in genotype distribution of CGRP979 between the two groups (P<0.05) ,with A/C predominating in patients with severe chronic periodontitis. Condusion: TNF-A-863 polymorphism is associated with severe chronic periodontitis; A/C of the CGRP979 loci might be a factor for severe chronic periodontitis.

Objective To investigate the relationship between the polymorphism of the tumor necrosis factor-αgene-308 promoter and bronchial asthma (BA)in Uighur and Kazakh population in Xinjiang.Methods PCR product sequencing method was used to detect the polymorphism distribution of TNF-αgene in 60 BA patients and 60 controls among Xinjiang Uighur and Kazakh population.Then we analyzed the association between different TNF-αgenotypes and BA in Uighur and Kazakh population.Results The distribution of GG,GA and AA genotype was significantly different between the two groups.Statistical analysis showed that BA group had a significantly higher TNF-αA allele frequency than that of the control one (P <0.05).After adjustment for sex and age,we found the A allele was a risk factor for BA pathogenesis (P <0.05).Conclusion The polymorphism of TNF-α gene-308 may be associated with the susceptibility to BA in Xinjiang Uighur and Kazakh population,so TNF-α gene-308 may be considered as a genetic marker for early identification of individuals at high risk for BA,which may play an important role in preventing the development of BA in clinical practice.

Objective To evaluate the effects of hemodialysis in aged patients with chronic renal failure,decrease complications,to improve their survival rate.Methods The clinical datas of aged patients suffering from CRF who received maintenance hemodialysis were summarized and analyzed about the survival,the cause of death and common complications.Results The commonest causes of death in aged patients with maintenance hemodialysis were cardiovascular events,infection and malnutrition.The common complications were cardiac insufficiency,infection.Conclusion Providing individual enough HD and treatment,improving nutritional situation,anemia and controlling infection may contribute to the reduction of the complications and the increasing of survival rate.

Objective To investigate the effect of high viral loads(HBV DNA concentration in blood ＞2.0 copy/ml)on the vertical transmission of hepatitis B virus in mothers with HBV DNA positivity.Method Forty pregnant women with HBV DNA positivity were divided randomly.double-blindly into 2 groups:at 28 weeks of pregnancy,one group received oral lamivudine(100 mg/d)and the other received oral placebo.The serum HBV DNA loads were tested at 28 and 40 weeks'gestation in mothers,and serum HBV DNA,HBsAg,HBeAg and anti-HBs were examined in infants at 12 month follow up.Result Thirtynine infants finished(one twins)the follow up,and 2 infants lost(5%).Among them 4 infants were confirmed to be HBV infection(10%,4/39),2 in the treatment group(10%,2/20)and 2 in the control group(11%,2/19)(P＞0.05).The serum HBV DNA levels of 40 weeks'gestation in the treatment group,compared with the levels of 28 weeks'gestation in the treatment group and 40 weeks'gestation in the control group,showed a significant decline(P＜0.01).The HBV DNA levels of the mothers whose infants were infected,were(3.1±3.4) copy/ml,(3.1±3.2) copy/ml during 28 and 40 weeks'gestation,and for mothers whose infants were non-infected,the levels were(3.4±2.2) copy/ml,(2.6±1.5) copy/ml respectively(P＞0.05).The mean values of anti-HBs of 18 infants in the treatment group showed no significant difference as compared to 17 infants in the control group,(594±416)U/L vs (458±398) U/L (P＞0.05).Conclusion The pregnant women's HBV DNA loads could be obviously decreased from high viral loads (HBV DNA concentrations in blood＞2.0 copy/ml)after they take lamivudine from 36 weeks'gestation.But it might not reduce the maternal-fetal vertical transmission of HBV infection.
