Objective To find out and compare the risk factors of the severe birth defects and mild birth defects,and make it more effective to prevent the severe birth defects.Methods Fetus diagnosed with severe birth defects in Shunde district,Foshan during 2016 were selected as case group 1,those who diagnosed with moderate/mild birth defects were selected as case group 2,and those healthy infants whose mother's last menstrual period was at the same time with the case groups were selected as control group.Their mothers' relative information was collected.A case-control study was conducted to analyze the risk factors of the two case groups respectively.We applied Chi-square analysis and multivariate Logistic regressions to find out the independent risk factors.Results Chi-square analysis showed that maternal age above 35 years(χ2=19.69,P<0.01) and gravidity 3 times or more(χ2=10.06,P<0.01) were the risk factors of severe birth defects,and twins was the risk factor of mild birth defects(χ2=4.05,P<0.05).The multivariate Logistic regressions showed that maternal age above 35 years was the independent risk factor of severe birth defects(OR=2.75,P<0.001),and twins was the independent risk factor of mild birth defects(OR=2.22,P=0.05).Conclusion The women with age above 35 years have higher risk to pregnant a baby with severe birth defects and they are worthy of more attention during pre-pregnancy and antenatal examinations.

Full thickness scalding of 37% TBSA was inflicted io rats. Three days later, the liver of the animals was isolated and the changes of the protein metabolism in the liver and the effects of insulin on the changes were evaluated.It was found that the protein and DMA levels of the liver showed no obvious changes after scalding, but the RNA content increased by 24% and the rate of leucine incorporation by 31%. After the addition of insulin, the leucine content increased by 23.% and 25.8% in the controls and the injured animals respectively. The results indicate that the rate of protein synthesis in the liver of the scalded animals increases, which is likely to be related to the increase of RNA content, and the liver protein synthesis remains to be sensitive to insulin.

This paper is to report the changes of the protein metabolism in the rat soleus muscle in vitro after 37% TBSA full-thickness burns covering one hindlimb and the effects of leucine and insulin on the burned muscle.It was found that there werea significant decreases of the protein content and marked exaggeration of the rates of tyrosine incorporation,tyrosine release and tyrosine net release in the burned muscle.No changes of the above-mentioned parameters could be revealed in the muscle of the unburned limb and the controls.Elevation of leucine concentration in the medium could not improve the protein metabolism of the burned muscle.0.1u/ml of insulin could significantly stimulate the tyrosine incorporation in the muscle of the unburned limb and the controls,but no similar effect was observed on the burned muscle.The results indicate that increased protein degradation of the local burned muscle is responsible for the postburn negative nitrogen balance;administration of leucine alone cannot improve the protein metabolism in the local burned muscle;and the sensivity of the burned muscle to insulin is suppressed.

Objective To study the clinical features, diagnosis,and treatment of hepatolithiasis complicated with cholangiocaminoma. MethodsClinical and pathological data were analysed retrospectively on 46 cases of hepatolithiasis complicated with cholangiocarcinoma. Results The results showed that the incidence of cholangiocarcinoma in hepatolithiasis was 4%, and 33% of patients were diagnosed as cholangiocarcinoma preoperatively. Tumor occurring in left intrahepatic ducts, right intrahepatic ducts, and hilar bile duct was 72%, 9% and 20%, respectively. Only 15(33%) cases underwent radical resection with 1-, 2-, and 3 year survival rate of 100%, 67% and 25% for the 12 cases that were closely followed-up. None of 15 cases receiving palliative bile duct drainage had survived for 1 year. KG2Conclusions Patients with a history of hepatolithiasis more than 10 years are under the risk of cholangiocarcinoma.During a surgery for hepatolithiasis a thorough exploration for the possible coexistance of cholangiocarcinoma is strongly recommended.

Lymph node metastasis is one of the main methods of metastasis and it affects the the prognosis of patients with gastric cancer. It is reported that the rate of tumor recurrence in patients with tumor-negative lymph nodes detected by routine pathology is approximately 25%, which is a factor that affects the survival. It is reported that the phenomenon associates with lymph nodes micrometastasis closely. The article will tou-ch the latest development on micrometsstasis.

Objective To find out the changes of endothelial cell function and coagulation-fibrinolysis system in maintenance hemodialysis(MHD)patients with diabetic nephropathy(DN).Methods The plasma levels of TM,PAI-1,TAT and PAP in 28 DN-MHD,34 non-DN MHD and 40 controls were measured by ELISA.Results (1)The levels of TM,PAI-1,TAT and PAP in both DN group and non-DN group were significantly higher than those in control group,P

Objective To find the application effect of risk management in nursing management in delivery room.Methods 1200 hospitalized parturients in 2011 were selected as the observation group,and 1186 parturients in 2008 were set as the control group.The observation group received risk management and nursing measures,while the control group was given traditional nursing.Nursing defects rates,the rate of post-partum haemorrhage,the incidence of neonatal asphyxia,dystocia rate,nursing disputes and patient satisfaction degree were compared between two groups.Results Neonatal label defects rates,the rate of post-partum haemorrhage,the incidence of neonatal asphyxia,dystocia rate and nursing disputes in the observation group were much lower than that in the control group.The patient satisfaction degree was significandy increased in the observation group.Conclusions Summarizing the risk factors,performing risk management in delivery room can greatly increase the delivery and nursing quality and patient satisfaction degree.

objective To study the inhibition effect and its mechanism of a non - cytotoxic chemotherapy drug in the growth of gastric cancer. Methods The inhibition effect was observed in the growth of xenotransplanted gastric cancer cells MKN45 with a gastrin receptor(GR) antagonist. On the basis of the determination of expressed GR in 34 patients with gastric cancer, we evaluated the preliminary clinical effect of PGL to gastric cancer with the positive GR. Results It is less tumor area, weight and gastric cancer cells DNA Index, average DNA contents and S phase fraction in PGL group than in control group. It is the least in PGL + SST group. GR is easy to be expressed in advanced gastric cancer of the body, cardia and fundus. With the 16-21 months follow- up of 14 patients with positive GR gastric cancer, we find that 2 patients died in control group of 8 patients, and all patients are alive in PGL group. Conclusion PGL can regulate the growth of gastric cancer cells MKN45. It would be able to improve the prognosis of gastric cancer.

Objective To explore the relationship between the amount of bleeding and the histopathologic grade of cerebral glioma with susceptibility weighted imaging (SWI), so that to assess the diagnostic value of SWI in grading cerebral glioma. Methods Totally 30 patients with cerebral glioma underwent SWI. The area of hemorrhage of every slice displayed in SWI was measured with software. The rate and amount of bleeding were compared between high and low grade tumors. Results There was no statistical significance in the incidence of detected bleeding on SWI (P=0.064), though it was higher in highly malignant group (80.00%) than that in low grade group (46.67%), while there was statistical significance in the amount of bleeding detected on SWI (Z=-2.275, P=0.026) between highly malignant group and low grade group. Conclusion The amount of tumor hemorrhage displayed in SWI is valuable for the preoperative grading of cerebral glioma.
