Objective:To explore the influence of background data in multinutrient treatment for neonate with infection pneumonia. To study the relative risk factors in VA nutritional state. Methods:the orally vitamin A and vitamin E,zinc, selenite daily in 111 neonates in the randomized,double-blind, placebo-controlled,clinical Trial for 7 days treatment. We investigated and analyze the relevant biochemical,immune evidence, clinic data and background data, with multivariate stepwise regression analysis. Results:Mother’s age, parity,gestation age and birth weight play positive influence to clinical restoring. Neonate’s age and birth weight play a positive role to serum IgM in early stage of pneumonia,but mother’ s age is negativity. Neonate’s age is positivity in enhancing serum VA,and is negativity in advancing serum IgM. Mother’s age play a negative role to heighten serum RBP. Conclusion:Mother’s age,parity,gestation age and neonate’s age is important factors to influence the clinical treatment effect. Great age and many parity mother’s neonate,earlier period and large for date infant are more possible to VAD during sick period,and are more slow to recover. So they need the nutritional intervention all the better.

0.05).There were statistical significant differences in the cellular immunity between the immunization and no-immunization group( P

The ultrastructure of magnetotactic bacteria strain WD\|1 was reported.A thin sectioned profile of it clearly showed its cell wall,cell membrane,poly\|?\|hydroxybutyrates and magnetosomes.Meanwhile,the method of batch culture of strain WD\|1 was also reported,135mg/L dry cells could be gotten with this method.The energy profiles of X\|ray collected after electron excitation in SEM indicated that both dry cells and magnetosomes contained such mineral elements as P,S,Ca,Si,Al and Fe with different content.The iron content of its cells and magnetosomes was 3 07% and 84 57% respectively.

The process of late lung development is disturbed in bronchopulmonary dysplasia (BPD).One of the keys in late lung development is secondary septation, in which secondary septa arise from primary septa, producing plenty of small alveoli, which significantly increase the surface area of gas exchange.Secondary septation,together with architectural changes to the vascular structure of the lung which minimize the distance between the blood and the inspired air, are the targets of late lung development.BPD is a disease of premature infants in which development of the alveoli is stunted caused by many factors including volutrauma,inflammation,and oxygen toxicity.Compared with early lung development, the later development of the immature lung remains unclear.This paper is to emphasize remarkable latest research of arrested late lung development and BPD.

Objective:To compare clinical therapeutic effects of simple TCM and simple western medicines on ulcerative colitis.Methods:Randomized effect model of Meta-analysis was used for quantitatively combined analysis on research literature about simple TCM treatment of ulcerative colitis with controlled study of simple western medicine from 2000~2004 in China.Results:Of 744 cases in the simple TCM treatment group,698 cases were clinically effective,and among 493 cases in the western medicine control group,335 cases were clinically effective.The stable rate total OR(odds ratio)=6.60,95%CI was(4.60,9.47) in the simple TCM treatment group,with significant difference between the two groups (P

Objectives:To study the effect of triptolide(Tri) on fibroblast cells in vitro culture, morphologically and kinetically. Methods:Light microscope(LM)and electron microscope(EM)were employed to detect the morphological changes in Tri group. Cell DNA content and apoptosis were assayed by flow cytometry (FCM). Results:In Tri group, fibroblast cells showed less density, slimmer body, abnormally and typical apoptosis under LM, while rarefaction and content of rough endoplasmic reticulum(RER) decrease, and apoptosis in different stages could be seen under EM. In FCM,AI elevated remarkably in Tri groups, and the effect is dose dependent, with cell cycle uninfluenced at all. Conclusions:The mechanism of triptolide on hypertrophic scars is related to its promotion on fibroblast apoptosis and inhibition of collagen excretion.

Objective To compare the influence of blood lipids and angina pectoris using combination therapy in coronary heart diseases(CHD) with unstable angina.Methods 100 patients were randomly divided into the probucol group(A group) 50 cases and probucol combined with atorvastatin treatment group(B group) 50 cases,The treadmill exercise ECG test,lipid and oxidation before and after treatment in two groups were observed.Results The total effective rate was 90.0% in group B significantly higher than 64.0% in group A(χ2 =3.841,P＜0.05);The total effective rate of ECG was 74.0% in group B after treatment which was significantly higher than the 42.0% in group A(χ2 = 3.981,P＜0.05);Treadmill exercise ECG test positive 82.0%,84.0% in two group before treatment,significantly higher than that 48.0%,24.0% in two group after treatment,(χ2 = 3.841,3.791,all P＜0.05);Angina pectoris in A、 B group after treatment [(1.6 ± 0.8) times、(1.0 ± 0.5) times]were significantly lower than [(4.3±1.9) times、(4.6 ±2.8) times]before treatment(χ2 =7.584,7.984,all P＜0.01).Conclusion Probucol was a safe and effective drug for treating hypolipidemic and reducing angina attack.Its combination with atorvastatin was safe,and the efficacy is more visible.

ObjectiveTo study the distribution and expression of NMDA receptor subunit 2A in the spinal cord of morphine tolerant rats. MethodsTwelve Sprague-Dawley rats were randomly divided into two groups with 6 rats each: control group (C) were intrathecally administrated 0.9% NaCl 10μl and morphine group(M) received 10μg morphine (i.t.). Drugs were administrated twice daily for 7 consecutive days. Tail flick latency (TFL) in the hot water immersion test was used to evaluate changes of thermal hyperalgesia latency of each group before and 30min after administration every morning. Rats were killed the day after last administration and L4～5 segment of the spinal cord was removed for determination the expression of NR2A by immunofluorescence method. ResultsTFL of group M was decreased gradually after chronic administration of morphine intrathecally. There was no significant difference between group M[(3.25±0.93)s] and group C[(2.66±0.27)s] on the 7th day (P＞0.05). A morphine tolerant model was established successfully. NR2A was distributed throughout the rat spinal cord. The expression of NR2A in group M(OD:9617±1233) was increased compared with group C(OD:2.66±0.93) (t=3.133,P＜0.05).ConclusionThe expression of NR2A was upregulated after repeated administration of morphine intrathecally in the superficial dorsal horn of spinal cord of morphine tolerant rats,which may be part of the mechanisms of morphine tolerance.

Tendons are dense connective tissues that mediate the attachment of the muscle system to the skeletal system. While the methods for clinical tendon repair remain less satisfactory, tissue engineering may pro- vide promising future. Therefore, understanding the natural tendon development process is important for tendon en- gineering. Scleraxis and Tenomodulin are relatively specific molecule makers for tendon and ligment and play im- portant roles in the tendon development. This article gives review of the molecular structure, the expression regula- tion, and the roles of Scleraxis and Tenomodulin in tendon development, in order to better understand the process of tendon development.

·AIM: To investigate the effect of hydralazine on choroidal blood flow in rabbits and laser-induced choroidal neovascularization (CNV) in rats and the effect of hydralazine on tube formation of human umbilical vein endothelial cells (HUVEC).used with raised intraocular pressure (IOP) of the left eye to 40mmHg.Hydralazine (10g/L) eye drops were instilled and ocular blood flow was measured with colored microspheres technique. Male Brown Norway rats were treated with Nd: YAG laser to break Bruch's membrane. Hydralazine (5, 10, 20g/L) eye drops or saline alone was instilled three times a day for 4 weeks after laser treatment. Fluorescein angiography (FA) and choroidal flat mount were used to measure the area of CNV. Tube formation of HUVEC was studied at different concen-trations of hydralazine.hydralazine eye drops enhanced the choroidal blood flow significantly at 30 and 60 minutes after drug instillation. After 4 week of drug treatment, 5, 10 and 20g/L hydralazine eye drops all reduced the CNV formation dramatically measured by fluorescein angiography and choroidal flat mount. When HUVEC was cultured on matrix gel for 48 hours, hydralazine at 3-30mg/L preven-ted the tube formation.vivo and HUVEC tube formation in vitro, and enhanced rabbits' choroidal blood flow after ischemia. It is hoped that hydralazine could be used to treat age-related ma-cular degeneration in the future.
