Methods Cortisol and DHEA S concentrations were measured By radioimmunoassay in 100 term fetal umbilical cord blood. They were divided into four groups. Group A selective cesarean section without any birth pain ( n =18),Group B cesarean section in latent phase( n =10),Group C cesarean section in active phase( n =12),Group D spontaneous vaginal deliver( n =60). Results The concentrations of fetal umbilical cord cortisol in spontaneous vaginal deliver group was gradually increased with gestational week. The peak level was in the 39th gestation week,by the 42th gestation week,the concentration of cortisol declined to the 37th gestation week. DHEA S changed paralleled with cortisol ( r =0.46, P

Experiments were carried out to investigate the effect of garlic, both fresh and old, on hypercholesterolemia. Forty healthy rabbits were equally divided into four groups, namely control, cholesterol, fresh garlic and old garlic. Except the control group, each rabbit in the other three groups was given 0.5g of cholesterol every day. The rabbits of fresh and old garlic groups were fed in addition respectively with fresh garlic, and garlic that had been stored for seven months, the doses being 2g for each. The results showed that fresh garlic had a significant effect of reducing diet-induced hypercholesterolemia and diminishing arteriosclerotic changes in aorta, but old garlic failed to show such effects.During the 50-day period when rabbits were fed with fresh or old garlic no toxic reaction was observed.

Using hybridoma technic, we prepared a group of hybridomas by different immunization procedures with(?)B erythrocytes, B erythrocytes plus B blood group substances or B blood group substances alone as antigens ,respectively. Three of them: 3-3-D9(IgG1) , 3-5-D1 2 (IgG1) and 6-1-G11 ( IgA ) which secreted high level and high specific monoclonal anti-B blood group substances were established. The agglutination titers of their tissue culture supernatant were 4096, 4096 and 16 384 by Takatsy microtitration assays. It was demonstrated that they were only specific to B blood group by hemagglutination specificity tests, hemagglutination inhibition assays and antibody dilution tests. They will be very useful in blood grouping to replace the human poly-clonal anti-B sera. Studies to determinate their combining site structures will be possible by these monoclonal antibodes.

Objective: To investigate the influencing factors for mild cognitive impairment (MCI) among the elderly inpatients of the department of geriatrics, so as to provide the reference for early screening and prevention of MCI in the elderly population. Methods: Inpatients aged 60 years and older and admitted to the Department of Geriatrics at the First Affiliated Hospital of Xinjiang Medical University were selected as the study subjects. Demographic information, past medical history, activities of daily living (ADL), depressive symptoms were collected through questionnaire surveys. MCI was diagnosed with Montreal Cognitive Assessment in combination with medical history and physical examination. Factors affecting MCI were identified using a multivariable logistic regression model. Results: A total of 1 019 elderly patients were collected, including 472 males (46.32%) and 547 females (53.68%), and had a median age of 73.00 (interquartile range, 14.00) years. Among them, 746 patients had an educational level of junior high school or above, accounting for 73.21%, 446 patients had cerebrovascular disease, accounting for 43.77%, and 220 patients were diagnosed with MCI, with a detection rate of 21.59%. Multivariable logistic regression analysis showed that age (OR=1.354, 95%CI: 1.285-1.426), educational level (primary school, OR=0.345, 95%CI: 0.163-0.731; junior high school or above, OR=0.196, 95%CI: 0.096-0.402), ADL (moderate/severe dependence, OR=4.744, 95%CI: 2.044-11.012) and cerebrovascular disease (OR=2.335, 95%CI: 1.482-3.679) were the influencing factors for MCI among geriatric inpatients. Conclusions The MCI of the elderly inpatients of the department of geriatrics is related to age, educational level, ADL and cerebrovascular disease. Therefore, targeted health education and cognitive function training should be provided for elderly patients to prevent MCI.

BACKGROUND:Theoretically, bone marrow-derived endothelial progenitor cells (EPCs) from liver fibrosis rats could be filtered by the pathological environment in vivo. These EPCs would be more adapted to the micro-environment of liver fibrosis, and easier to differentiate into mature endothelial cells participating in the intrahepatic vascular remodeling after transplanted into the liver.OBJECTIVE:To explore the effectiveness of transplantation of bone marrow-derived EPCs from the liver fibrosis environment in liver fibrosis rats.METHODS:Twenty-eight Wistar rats were randomly divided into three groups as follows:normal group (n=8) were injected with olive oil, twice per week; model group (n=10) were infused with carbon tetrachloride at a dose of 3 mL/kg body weight (double doses for the first time), twice per week, and infused with normal saline through the tail vein at 2, 3 and 5 weeks; EPCs transplantation group (n=10) were infused with carbon tetrachloride at a dose of 3 mL/kg body weight (double doses for the first time), twice per week, and infused with EPCs suspension through the tail vein at 2, 3 and 5 weeks. Six weeks after final injection, the angiogenesis, hepatocyte proliferation and pathological changes in the liver tissues were observed. The liver function and coagulation function were tested.RESULTS AND CONCLUSION:(1) The pathological changes of the liver:in the model group, fatty degeneration and hepatocyte necrosis in the liver tissue were serious, inflammatory cells were infiltrated around the portal and central vein,the portal areas expanded, and fibrous tissues overgrew. Compared with the model group, these changes were significantly relieved in the EPCs transplantation group (P < 0.05). (2) The expressions of liver-related proteins:compared with the normal group, the levels of hyaluronic acid, laminin, type III procollagen, vascular endothelial growth factor, epidermal growth factor were significantly increased in the model group (P < 0.05). Compared with the model group, the levels of hyaluronic acid, laminin and type III procollagen were decreased significantly (P < 0.05), and the levels of vascular endothelial growth factor and epidermal growth factor were increased in the EPCs transplantation group (P < 0.05). (3) Liver function and coagulation function:compared with the normal group, the liver function and blood blotting function of rats were seriously damaged in the model group (P < 0.05). Compared with the model group,the liver function and coagulation function were obviously improved in the EPCs transplantation group (P < 0.05). To conclude, transplantation of bone marrow-derived EPCs from the liver fibrosis environment is effective for liver fibrosis in rats. The mechanism may be associated with the promotion of angiogenesis in the liver.

Objective To compare the diagnostic performance of prospective electrocardiogram (ECG)-gating 320-detectorcomputed tomography coronary angiography (CTCA) versus retrospective ECG-gating CTCA. Methods 500consecutive patients suspected coronary artery disease with heart rate of less than 65 bpm were performed coronary computed tomography angiography (CCTA) with prospective (group P)and retrospective (group R) ECG gating in turn. The image quality was divided into four levels. Success rates, effective radiation dose,image quality and diagnosis were evaluated. Results Success rates of examination in group P and R are100%.Mean patient radiation dose was significantly different in group P (3.28±1mSv) and R(14.36 ±2.3 mSv).131 and 142 of 3750 segments (250 patients x 15 segments per patient) were too small(1.5mm)tobe characterized in group P and R. 96. 51% (3619/3750) and 96.12% (3608/3750) characterized segments were not significantly different in group P and R. 95.09% segments received a score of 4 and 1.09% segments received a score of 3 in group P, while 95.23% and 0.74% in group R.The cause of 2 and 3 points in the two groups was motion artifact. Stair-step artifacts and images scored as 1were not found.Compared with CAG,the sensitivity,specificity,false positive andfalse negative value in group P(86. 49% ,98. 70% ,88. 89% ,98.38%) and R(83. 87% ,98.74% ,89. 65%,97.93%) were not significantly different. Conclusion Although the patient radiation exposure was significantly lower, the diagnostic performance of prospective ECG-gating 320-detector CTCA was comparable with that of retrospective ECG-gating 320-detector CTCA on patients with stable heart rates less than 65 bpm.

Objective To study the nutritional risks in elderly patients with prostate cancer and explore its related factors.Methods 346 elderly patients with prostate cancer in Wuhan area from May 2013 to May 2014 were chosen as the objects in this study.Nutritional risk screening 2002 was used to evaluate nutritional risk.The sleep quality,anxiety,lower urinary tract symptoms,differentiation and other data of patients were collected.The influencing factors for nutritional risk in the patients were analyzed.Results The ratio of nutritional risk in elderly advanced prostate cancer patients was 35.3％ (122/346).The nutritional risk was increased with age (P＜0.05).The prostate cancer patients with nutritional risk had a higher international prostate symptom score (IPSS) (P＜ 0.05).Monovariate factor analysis showed that sleep quality,operation,pathology staging,radiotherapy,chemotherapy,lower urinary tract symptoms (LUTS) were the impact factors for nutritional status in elderly patients with prostate cancer (P＜0.05).Logistic regression analysis showed that age (OR=0.29),sleep quality (OR=0.25) were the protective factors for the nutritional status,while surgery (OR=12.67),pathological staging (OR=1.65),radiotherapy (OR=2.65),SPSS (OR=1.55),chemotherapy (OR=1.85) were the risk factors for nutritional status (P＜ 0.05).Conclusions The incidence of nutritional risk is high in elderly prostate cancer patients.Age,sleep quality are the protective factors,and operation,pathology staging,SPSS,chemotherapy,and radiotherapy are the risk factors for nutritional status.

Objective To evaluate the collateral circulation after canine acute coronary artery occlusion with contrast real-time three-dimensional echocardiography (RT-3DE). Methods Left anterior descending coronary artery was ligated in 12 healthy mongrel dogs. All dogs underwent myocardial contrast echocardiography (MCE) before ligation, immediately after ligation, at 30 min and 180 min after ligation respectively, and myocardial mass with collateral supply was calculated. Results Different degrees of collateral circulation were established in all dogs after left anterior descending coronary artery ligation. At 30 min after ligation, the myocardial mass with collateral supply was (9.65±2.90) g, while at 180 min after ligation were (12.58±3.98) g (P<0.01). Conclusion The coronary collateral circulation can be observed clearly and myocardial mass with collateral supply can be quantified accurately with contrast RT-3DE.

Objective To observe the value of two-dimensional speckle tracking imaging (2D-STI) in assessing regional myocardial viability of rats after acute myocardial infarction. Methods Twenty Wistar rats were randomly divided into acute myocardial infarction group and sham-operation group (each n=10). Echocardiography was performed at baseline and 24 h after reperfusion. High frame rate two-dimensional images were recorded from the left ventricular short-axis views at the papillary muscle level. Peak radial strain (PRS) and peak circumferential strain (PCS) of each segment were measured at systolic period. Left ventricular internal diameter at diastole (LVID_d) and systole (LVID_s), fractional shortening (FS), ejection fraction (EF), wall thickening rate (TR) were measured with anatomical M-model echocardiography. Area of necrosis (AN) of each segment was measured after triphenyl tetrazolium chloride (TTC) staining. Based on TTC staining, ROC curve was used to analyze the accuracy of two-dimensional strain and TR index in identifying infarcted segment. Results ①Compared with acute myocardial infarction group at baseline and sham-operation group after operation, LVID_d and LVID_s of acute myocardial infarction group after operation increased significantly respectively (P<0.05), FS, EF and anteroseptal wall TR reduced significantly (P<0.05). ②Compared with acute myocardial infarction group at baseline and sham-operation group after operation, PRS and PCS decreased significantly in anteroseptal, anterior, anterolateral, inferolateral and inferoseptal segments of myocardial infarction group after operation (P<0.05), especially in anterosepetal, anterior and anterolateral segments (P<0.05). ③ROC analysis showed PCS had the best ability to identify infarcted myocardium as defined by AN>50%. Using a cut-off of -6.14%, PCS had a sensitivity of 93.75% and specificity of 90.91% for distinguishing infarcted from viable myocardium. Conclusion 2D-STI can accurately quantify regional myocardial function, providing a sensitive and noninvasive means to assess regional myocardial viability.
