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

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.

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.

Clinically,peripheral nerve injury is common,treatment is still a clinical problem.Because of the peripheral nerve's particular dissection and the function,repair of its damage is a complex process,meticulous microsurgical technique can be used to restore nerve continuity,but the restoration of nerve function is still not satisfactory.Recently,the domestic and foreign scholars has made effort and achieved some success,particularly,the allograft nerve transplant has applied in clinical.

Objective: Through summarizing the main problems and challenges faced in the medical health system reform in China , suggestions are given: the government needs to erhance the health investment and play the role of market mechanism , make the use of electionical information technique, further change the community system of implementing medicine community system, implement the medical service supervision system.

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 determine the location of mycobacterium tuberculosis(MTB) and whether the cellular immunity is induced after intragastric administration of BCG in mice.Methods:Viable MTB were detected in mesenteric lymph nodes?spleen and lungs at day 15,30 and 60 after intragastric administration of BCG to mice.The proliferation of T-lymphocyte with the stimulus of the purified protein derivative(PPD) was measured at day 60 and 90 after intragastric administration of BCG to mice.The expression of interleukin-2(IL-2) of T-lymphocyte in spleen was detected at day 60 and 90 after intragastric administration of BCG.Results:Viable MTB were detected in the mesenteric lymph nodes and spleen at day 15,30 and 60 after intragastric administration.At day 60 and 90 after intragastric administration of BCG to mice,the ratio of T-lymphocyte proliferation was 31.32%,37.94% separately and the production of IL-2 was 37.47?5.60 U/ml,39.41?7.73 U/ml separately.There were no statistically significant differences in the cellular immunity between the mice of the intragastric administration of BCG significant differences in the cellular immunity between the mice of the intragastric administration and the mice of the subcutaneous vaccination of BCG( P 0.05).Conclusion:Intragastric administration of BCG can induce cellular immunity in mice.

Objective To investigate the incidence of the nosocomial infection in patients of Shenzhen district polyclinic,provide solution for controlling the nosocomial infection and give precautionary measures for the future.Methods By prospective and retrospective combinative case-control methods,the incidence of nosocomial infection of the in-patients during May 2002 to December 2004 was investigated and analyzed.Results There were 237 patients and 251 cases of nosocomial infection from 10271 in-patients.The incidence of nosocomial disease was 2.31%.The infection rate was 2.44%.Conclusion In the basis of completely utilizing the third-class network management in nosocomial infection,the precautionary nosocomial infection can be effectually controlled by monitoring and enhancing staff training.

Objective To explore the clinical effect by using of 654-2 to multigravidae.Methods Among 60 multigravidaes deliverying,30 were treated with 654-2 and oxytocin,the other 30 multigravidaes were treated with oxytocin only for control.The time of dilatation of the cervix,the rate of fetal distress and neonatal asphyxia,the rate of operative delivery and postpartum hemorrhage were observed.Results The time of dilatation of the cervix and the rate of operative delivery were shorter than the control.It was significantly different between the two groups(P0.05).Conclusion 654-2 can promote the first stage of the multigravidae.It can reduce the rate of operative delivery.It is safety by using of 654-2 to short the first stage to multigravidae.

Glutamine(Gln) is the most abundant free amino acid in the circulation. However, Gln depletion is obviously increased in critically ill patients. The liver plays a key role in glutamine metabolism since it can either generate or consume Gln. A number of studies have demonstrated that administration of Gln can protect from liver damage during sepsis or chemotherapy. The mechanism may be that glutamine can be more efficiently transported across cell membranes for glutathione synthesis. Supplement of Gln to PN has been proven to maintain intestinal integrity and reduce bacterial translocation. As a gluconeogenic amino acid, Gln can decrease the portal insulin/glucagon ratio and prevent hepatic steatosis through stimulating glucagon secretion.
