Objective To evaluate if replication-defective herpes simplex virus mediated kynurenine aminotransferase Ⅱ (HSV-KAT Ⅱ) could inhibit detrusor overactivity (DO) in rats with spinal cord injury by bladder wall injection.Methods From June 2012 to July 2013,48 male Wistar rats with T10 spinal cord transection (SCT) were randomly divided into normal saline group,HSV group and HSV-KAT Ⅱ group (n=16 each group).Normal saline (40 μl),HSV or HSV-KAT Ⅱ (40 μl,1×107 plaque forming unit viruses) was injected into the rat bladder wall of according group by 1 week after SCT.Three weeks after injection,cystometry was performed and the virus transfected efficiency,expression of KAT Ⅱ in L6-S1 dorsal root ganglia were examined.Results The DO number,DO amplitude,maximum voiding pressure and volume inducing voiding were decreased significantly by 59.6％-61.1％,21.6％-24.2％,30.3％-34.4％ and 44.1％-46.5％ (P＜0.01),while voiding efficiency,the time to first DO were increased significantly by 40.7％-47.7％ and 30.1％-49.0％ (P＜0.01) in the HSV-KAT Ⅱ group compared with normal saline group and HSV group.However,the leaking volumes were no significantly different among the 3 groups (P＞0.05).The relative intensity of KAT Ⅱ protein (0.50±0.13 versus 0.28±0.07,P＜0.05) and mRNA (0.78±0.06 versus 0.51±0.08,P＜0.01) were increased significantly in HSV-KAT Ⅱ group than those in HSV group.Conclusion HSV-KATⅡ bladder wall injection inhibits DO and may improve detrusor-sphincter dyssynergia in rats with spinal cord injury.

Objective To observe the radiological feature of chest X ray in SARS patients. Methods The chest films of 54 cases of SARS were reviewed in the study. The chest film features and site of lung involvement were studies in early stage, most severe stage and recovery stage. The correlation between the score of lung involvement and clinical course was also studied. Results 79.63% cases had abnormal chest films in early stage. Most of them (72.22%) were found in 3～7 days after onset. The lung involvement was most common in bilateral (88.89%) and most in middle and lower field (46.30%). Exudation and consolidation lesions showed to be dominant. The lesions progressed quickly and showed to be variable. There are 17 (31.48%) cases had second peak in X ray, the mean time of onset is 14.71 days. The chest X ray is not parallel with clinical syndrome. The absorption of lung infiltrates is correlation with glucocorticosteroids treatment in 20 patients, and the correlation is not found in 26 patients.Conclusions The chest X ray of SARS has some features and its changes can reflect the clinical situation.

0.05) . Significant decreases of contents of 14 kinds of macro-elements and trace elements in purified water were found compared with those in water samples after activated carbon filtration (t = 2.496 9-5.261 7, F2 and showed significant dose-response relationship respectively (r = 0.980, P

Objective:To improve the efficient use of assets, prevent and eliminate the waste and loss.Methods: We improved the standards of medical scrapped evaluation and made full use of the residual value of scrapped equipment for the issues that the program and technical appraisal of medical scrapped evaluation were not standardized, the residual value was not accurate and the disposal was too careless, etc.Results: The residual value was useful for the standard and reasonable approval process of scrapped medical equipment.Conclusion: The perfect disposal process of medical equipment ensures that the fixed assets of hospital are complete and security. Making full use of residual value of the scrapped equipment can increase efficiency of the use of hospital assets and eliminate the waste of assets.

Objective To study the influence of the Runzaoling on AQP1 and AQP5 in submaxillary gland of mice with Sjogren syndrome.Methods Sjogren syndrome mice models were setup by innducement method and divided into six groups randomly,including A group(blank group),B group(model group),C group (low dose group),D group(moderate dose group),E group(high dosage group)and F group(prednisone group).Immunohistochemical method was used to detect the of expressions of AQP1 and AQP5 of submaxillary gland in model mice.Result AQP1 expression showed:scattered flavescent particles were only found in submaxillary gland of group B and group C;AQP5 expression showed:brown-stained granules can be found in gland alveolous teleblem,lateral membrane,and basal lamina of submaxillary gland,secretory duct,and duct epithelia in B group mice;light brawn-stained granules can be found in group C mice;attenuated or disappear stained granules were found in acinus,secretory tube,and duct in D,E,and F group mice.Conclusion Runzaoling Can raise the expression of AQP5 in submaxillary gland of SS mice and increase the absorption quantity of water.

Objective To investigate the intakes of dietary nutrients and the growth and development status among children with autism,to propose scientific basis for developing further interventions.Methods Dietary intakes of nutrients were obtained with the method of 24-hour dietary review for 3 days.Meanwhile,the height and weight were detected among the subjects;Z-score was also adopted to evaluate nutritional status.Results 1.About 31.5% of the 111 cases with autism were overweight or obesity and 8.1% of the children were acute or chronic malnutrition.2.The intakes of 11 nutrients were insufficient,especially VA,VC,VB6,folate,calcium and zinc,had a serious shortage that less than 60% of the recommended intakes.3.The crowd was widespread lack of nutrients,39.6% of the cases with nutritional deficiency in varying degrees,the incidences of calcium and zinc deficiency were reach up to 88%.Conclusions The nutritional deficiency and overnutrition were simultaneous among the children with autism,their dietary nutritional supplement were generally inadequate.More sufficient measures and rational diet are necessary to improve the nutritional status for the autistic children.

Aim To establish an in vitro insulin resistant model of HepG2 cells and 3T3-L1 adipocyte and to screen drug in vitro.Methods The insulin resistant models of HepG2 and 3T3-L1 adipocyte were induced by high concentration of insulin and by dexamethasone,respectively.The glucose consumption ofcells was detected after administration with different drugs. Results In the concentration of 10-6 mol?L-1 insulin for 36 hours,HepG2 cells were resistant to insulin and the insulin resistance was maintained for 48 hours without change of cell morphology.After 3T3-L1 adipocyte insulin resistance was induced by dexamethasone,the maximal difference of glucose consumption between the blank control and insulin resistant model group was observed at 96h after dexamethasone administration,but the insulin resistant status had only been maintained for 24 hours without dexamethasone.The glucose consumptions of insulin resistant model of HepG2 and 3T3-L1 adipocyte were promoted by some drugs such as stachyose,berberine and ginsenoside.Conclusions The insulin resistant model of HepG2 cell and 3T3-L1 adipocyte was successfully established in vitro by high concentration of insulin and by dexamethasone,respectively.It can be used to screen drugs for treatment of insulin resistance.

The improvement of electrophoresis for DNA fingerprinting has been carried out. The time of electrophoresis was shortened,and 1/3-1/2 of reagents were saved. The minimal amount of DNA samples for DNA analysis was 0.8?g. It is worthy to popularize and apply in practice.

Objective To investigate the clinical significance.of thrombocytopenia in systemic lupus erythematosus (SLE).Methods One hundred and two SLE patients with thrombocytopenia who were admitted to Peking University People's Hospital were involved in the study.SLE patients without thrombocytopenia were controls.Clinical and laboratory characteristics were analyzed.T-test and Chi-square test were used for inter-group comparison.Results Patients with thrombocytopenia had more organ damage than those without,although the disease activities (SLEDAI) were not different between these two groups.Bone marrow characteristics were analyzed and 16 patients were amegakaryocytic.However,there were no differences observed between patients with amegakaryocytosis and normal megakaryocytes in organ damage,disease activity and response to therapy.Conclusion Lupus patients with thrombocytopenia usually have more organ damage.About 32％ of those patients are amegakaryocytosis.
