Objective To study the influence of microinflammation factors on the pregnancy outcome in gestational diabetes mellitus (GDM) patients.Methods Forty-eight GDM women with abnormal hsCRP and IL-6 concentration were selected as study group another 36 GDM women with normal concentration as control group.The difference of the two groups in common data and outcomes of pregnancy were retrospectively analyzed.Results There were significant difference in hypertensive disorders,prom,premature delivery,intra-uterine asphyxia,mega fetus,uterine-incision delivery and fetus hypoglycemia hypocalcemia between two groups (P ＜0.05).Conclusions Microinflammation factors have promote influence on the development and outcomes of GDM.Early diagnosis and impose intervention may have positive effect.

Intestinal mucosal barrier has the function to isolate intestinal contents and internal environment,prevent foreign antigens and pathogens invading to lamina propria mueosae and can maintain organic homeostasis and normal activities.Impairment of the intestinal barrier is a key event in various gastrointestinal diseases.Probiotics are live microorganisms which ingested and reach the intestines in sufficient numbers to confer benefit to the host.It can improve or prevent many gastrointestinal diseases.The main reason is probiotics can maintain intestinal barrier function in various paths.This paper reviews its mechanisms of action.

Inflammatory bowel disease(IBD) is a recurrent chronic nonspecific intestinal inflammatory disease which can be seen at any age.Its pathogenesis is not clear and the incidence is increasing.Intestinal mucosal barrier has the function to isolate intestinal contents and internal environment which can prevent pathogens invade to lamina propria mucosae and maintain organic homeostasis and normal activities.Impairment of intestinal barrier is a key event in various gastrointestinal diseases,such as IBD.The dysfunction of intestinal mucosal mechanic barrier,immunologic barrier and biologic barrier or their interactions all can induce gastrointestinal diseases.Identifying the specific mechanism of intestinal mucosal barrier impairment in pathogenesis of IBD,maintaining and restoring intestinal barrier function is becoming a new strategy in the treatment of IBD.

Objective To investigate the correlation between occurrence time and condition severity in patients of bronchial asthma complicated with allergic rhinitis. Methods The 583 outpatients with asthma in an asthma clinic during 1996-2002 were divided into simple asthma group (Group Ⅰ with 292 cases) and asthma complicated with allergic rhinitis group (Group Ⅱ with 291 cases), and their data were compared and statistically analyzed. Results The proportion of those complicated with other diseases, e.g. , nasal polyp, sinusitis, atopic dermatitis, and with a history of allergy, e.g. , food allergy, drug allergy and positive skin allergic test, was significantly higher in the Group Ⅱ than that in the Group Ⅰ ( P

Individual susceptibility to cancer induced by environmental agents may be influenced by polymorphic metabolic genes responsible for the activation or detoxification of carcinogens．The association between genetic polymorphisms in cytochrome P4501A1 (CYP1A1) and lung cancer susceptibility has been extensively studied．The various CYP1A1 alleles exhibit population frequencies that depend on race and ethnicity．An increased risk of lung cancer in Asians was found to be associated with genetic polymorphisms in CYP1A1．However，reports from Caucasians are not consistant，probably suggesting the ethnic-sepecific effect of the polymorphisms in the locus on the cancer．Evidence also exists for the association between levels of carcinogen-DNA adducts or frequency of oncogene and tumor suppressor gene mutations and CYP1A1 polymorphisms．These findings provide a better understanding of the relationship between CYP1A1 and lung cancer susceptibility．

Educational narrative is the application of narratology in the field of education.This paper introduced the definition of educational narrative and its characteristics of life,situationality and reflexivity,and then discussed the applicableness of the application of educational narrative in the medical ethics education.Based on this,it proposed the effectiveness means,namely that to improve theory quality and enhance the ability of narration,clarify the narrative theme and select material carefully,take care of medical students' growth and listen to their voice.

ObjectiveTo investigate the effect of age and gender on the position of termination of the conus medullaris (CMT).MethodsOne thousand three hundred and thirty-nine patients aged 4-89 yr scheduled for lumbar magnetic resonance imaging examination were selected.The position of CMT was determined using Visart 1.5 T or Magnetom Trio 3.0 T magnetic resonance imaging instrument.Results Five hundred and ninety-four male patients and 745 female patients were enrolled in the study.There was no significant difference in the percentage of CMT located at the L2,3 intervertebral disc level between female (1.2％) and male (0.5％) patients (P＞0.05),and female patients had a lower mean CMT than male patients (P＜0.01).There was no correlation between age and mean CMT in patients aged ≤19 yr (P＞ 0.05).There was a positive correlation between age and mean CMT in female patients aged≤20 yr (r =0.076,P＜0.05),but there was no correlation between age and mean CMT in male patients aged ≤ 20 yr (P＞0.05 ).ConclusionFemale patients have a lower mean CMT than male patients,and there is still a risk when performing spinal anesthesia,although the probability that CMT located at the L2,3 intervertebral disc level is low in female and male patients.The position of CMT is lower with increased age in adult female patients,but it is not related to age in adult male patients.

Objective To study the applicability of ultrafiltration of tween-80 and it solubilizing schizonepeta volatile oil and paeonol of ultrafiltration. Method Taking components content as index, temperature, pressure, concentration and membrane pore size were selected as factors for orthogonal design method. The concentration was determinated in medical solution before and after ultrafiltration, and the transmittance rate (TS) was calculated to observe the content variation of tween-80 and it solubilizing solution. Results The four factors had markedly effect on TS of tween-80, concentration was statistically significant (P

Objective To observe the effects of Qifuyin on learning and memory ability and expression of somatostatin in hippocampus on Alzheimer’s disease (AD) rats. Methods SD rats were randomly divided into blank control group, sham operation control group, model group, donepezil group and Qifuyin group. The AD model was established by microinjection of A?1-42 into the bilateral hippocampus. The learning and memory ability of rats were evaluated with a series of tasks to find a hidden platform in Morris Water Maze. The expression levels of somatostatin in hippocampus were measured by immunohistochemical SP techniques. Results In the place navigation test, the mean escape latencies of the model group was obviously increased compared with sham operation control group (P

Objective To compare the effect of hepatic oval cells and bone marrow mesenchymal stem cells to treat liver fibrosis in mice. Methods The C57BL/6 mice were fed with 3,5-diethoxycarbonyl-1, 4-dihydro-collidine (DDC) in a standard food at a concentra-tion of 0.1% to activate the oval cells proliferation, then the nonparenchymal cells were separated by in situ perfusion and density gradient centrifugation, and finally Sca-1 antibody was used in conjunction with magnetic activated cell sorting (MACS) to separate the Sca-1 +cells. Other mice were injected subcutaneously with CCl4 to establish experimental liver fibrosis model. Finally, the fibrosis mice were trans-planted with HOC or MSC or saline by spleen injection according to the group they belonged to. Four weeks later, the liver function index, the hydroxyproline and the histopathological change among the groups were used to evaluate the effect of the treatment. Result The liver function index was improved after transplantation. HOC and MSE treatment could reduce both the hydroxyproline level and alleviate the fibro-sis, but HOC seems more effective in the group with continuing CCl4 injection(P < 0.05). When stopping injecting CCl4, the change of fi-brosis was not visible(P >0.05). Conclusion Both hepatic oval cells and bone marrow mesenchymal stem cells can improve the liver function, and alleviate the fibrosis level by transpleen transplantation, but hepatic oval cells were more effective.
