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.

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.

Background:Gastric cancer is the result of comprehensive interactions among Helicobacter pylori(Hp)infection, environmental factors and host genetic factors. It has been demonstrated that rs2294008 polymorphism in prostate stem cell antigen(PSCA)gene is associated with increased risk of non-cardia gastric cancer. Aims:To investigate the relationship between PSCA rs2294008 polymorphism and precursors of gastric cancer. Methods:A total of 398 patients with gastric intestinal metaplasia( n = 328)and intraepithelial neoplasia( n = 70)from Nov. 2009 to Nov. 2015 at the Qingdao Municipal Hospital were enrolled,and 416 healthy subjects were served as controls. Genotype of PSCA rs2294008 was determined by direct DNA sequencing of PCR products,and Hp infection was examined by rapid urease test. Results:Significant difference in frequencies of CC,CT and TT genotypes of PSCA rs2294008 was observed between case and control groups(P = 0. 011);the frequency of TT genotype was significantly higher in case group than in control group (16. 3% vs. 9. 4% ,P = 0. 003). Compared with individuals carrying CC genotype,TT genotype carriers were found to be associated with a higher risk of precursors of gastric cancer(oR = 1. 840,95% CI:1. 174 ~ 2. 886). Taken individuals negative for Hp infection and carrying C allele(CC + CT)as reference,risk of precursors of gastric cancer was significantly increased by Hp infection(oR = 2. 389,95% CI:1. 799 ~ 3. 173)and Hp infection in combination with TT genotype (OR = 3. 335,95% CI:1. 935 ~ 5. 749),whereas TT genotype alone only slightly increased the risk(OR = 1. 783,95%CI:0. 900 ~ 3. 530). Conclusions:PSCA rs2294008 polymorphism is significantly associated with susceptibility to precursors of gastric cancer and Hp infection might further increase the risk in TT carriers.

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

Objective To explore the role of Neuroretinal Rim Volume/ Rim Area(RV/RA) ratio in Early Diagnosis of Primary Open Angle Glaucoma(POAG).Methods All candidates were divided in to three groups(31～40 years old,41～50 years old,51～60 years old),Heileberg Retina Tomography(HRT)were used to test retinal disk,and the RV/RA ratio were calculated.Result There are obviously difference between nomal and POAG group in RV/RA(P

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.
