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.

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.

Objective Using principal components analysis and weighted TOPSIS method to make objective and accurate evaluation of hospital operation management quality.This aims at proving whether such methods are scientific and feasible for comprehensive evaluation for the quality of hospital operation management and providing the basis for hospital decision making.Methods 15 typical Hospital Performance Indicators were chosen from a cancer hospital during 2008-2012,which were subject to TOPSIS method and principal components analysis,weighted TOPSIS method for comprehensive evaluation.Results The results with principal components analysis and weighted TOPSIS method conform to the actual hospital conditions and prove the rising quality of operation management of the hospital.That is,the closer the date,the higher the ranking.Conclusion Principal components analysis and weighted TOPSIS method are proven flexible,practical,scientific and reliable and suitable for popularization and application in the quality evaluation of hospital operation management.

Objective To investigate the relationship between the doses of epidural morphine administered for postoperative analgesia and postoperative urinary retention (POUR). Methods Sixty ASA Ⅰ patients aged < 20-56 yr undergoing atthroscopic knee operation under epidural anesthesia were randomly divided into 3 groups ( n = 20 each) : group Ⅰ and Ⅱ received epidural morphine 1 and 3 mg in 5 ml of normal saline (NS) respectively at the end of operation (group M1, M2 ); group Ⅲ received NS 5 ml instead of morphine (group C). Urinary retention was defined as the patient could not void, when bladder volume was ≥ 600 ml measured using ultrasound. Bladder urine volume was measured before anesthesia and at 4, 6, 8, 10 and 12 h after operation. The occurrence of urinary retention, the first postoperative voiding time, VAS scores and the incidences of vomiting and pruritus were recorded. Results The 3 groups were comparable with respect to age, M/F sex ratio, preoperative bladder urine volume, the amount of local anesthetic used during operation and duration. The incidences of urinary retention, vomiting and pruritus were 65%, 60% and 90% respectively in group M2 and significantly higher than those in the other 2 groups. The first postoperative voiding time was significantly longer in group M2 than in the other 2 groups. VAS scores were significantly lower in group M1 and M2 than in group C. There was no significant difference in VAS scores between group M1 and M2. Conclusion Epidural morphine increases the incidence of POUR in a dose-dependent manner, and 1 mg is the recommended dose.

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.

Embarking from the people's livelihood science and technology, it is the important direction of new time health work to impel the medicine science and technology to serve the people's livelihood and to develop the people's livelihood. And it is also the request inevitably of the reform of health and medical community institutional. This article discussed the basic content of the people's livelihood science and technology, expounded that the medicine is the important component of the people's livelihood science and technology and has an important position in the development of the people's livelihood science and technology. At the same time, the article analyzed the problems which exist in the service of people's livelihood, of medicine science and technology in the current. And it was proposed that the policy should be reformed and innovated to speeds up the medical science and technology service of people's livelihood.
