2.Multivariate analysis of the influential factors in multinutrient treatment for neonate with infection pneumonia
Journal of Chongqing Medical University 2003;0(06):-
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.

4.Relationship of PSCA rs2294008 Polymorphism with Precursors of Gastric Cancer
Chinese Journal of Gastroenterology 2016;21(12):733-736
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.
5.Advances in arrested late lung development and bronchopulmonary dysplasia
International Journal of Pediatrics 2015;42(6):615-618
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.

Chinese Journal of Immunology 1986;0(04):-
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.

9.AN EXPERIMENTAL STUDY USING INDOCIN TO INHIBIT THE OTOTOXICITY INDUCED BY FUROSEMIDE
Medical Journal of Chinese People's Liberation Army 1982;0(03):-
We have observed the protective effects of indocin (IND), a potent inhibitor of pro-sglandins (PGs), on ototoxicity induced by furosemide (FU) using the synchronous recording technique of endocochlear potential (EP) and auditory action potential(AP) in guinea pigs. The FU group were found to have a mean decrease in EP of 65.1?5.6mV and AP amplitude 91.5?10.2%. In contrast, the animals in the FU+IND group had a much smaller reduction of EP(17.5 ?3.8mV) and AP amplitude(31.1?4.7%). The rate of return in EP and AP was much faster in the FU+IND group as compared with the other group. Our findings suggest that the ototoxicity of FU may be related to the mediation of PGs in the inner ear target tissues. IND can interrupt an increase in endogenous PGs in cochlear tissues triggered by FU injection by inhibiting the biological synthesis of PGs, thus effectively diminishing the ototoxicity induced by FU.
10.Co-culture mode of tissue-engineered tracheal epithelial cells and fibroblasts: Comparison with routine culture
Chinese Journal of Tissue Engineering Research 2007;0(15):-
AIM: To establish the co-culture mode of tissue-engineered tracheal seeding cells, and compare with the routine culture, so as to provide the fundament of tissue-engineered trachea construction by cell compound materials. METHODS: The experiment was completed at the laboratory, Department of Respiratory Diseases, Tangdu Hospital, the Fourth Military Medical University of Chinese PLA from May 2006 to May 2007.①Three healthy New Zealand male rabbits, weighed (250.00?0.75) g, were used in this study.②Co-culture mode: The tracheal epithelial cells and fibroblasts were isolated and then co-cultured for 7-10 days. The two kinds of cells were distinguished according to their different tolerances to trypsin. Subsequently, A hole received 0.5 g/L trypsinization, cells were suspended in DMEM medium containing 0.05 volume fraction of CO2 and then transplanted into B hole (fibroblasts); again, A hole was added with 2.5 g/L trypsin for digestion, afterwards cells were suspended with K-FSM medium and transplanted into C hole (tracheal epithelial cells). Routine culture: after isolation, tracheal epithelial cells were cultured and fibroblasts were purified, respectively.③The co-cultured cells and the traditionally cultured cells were compared via cell growth curve and cell proliferation detected by 3-(4,5-dimethylthiazo-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay. RESULTS: ①Cell growth: Co-cultured cells grew well, those in A hole increased intercellular apace after trypsinization, while cells in B hole were shaped as fusiform, without the manifestation of typical road stone-like cells, and cells in C hole were apposite, showing lamellar road stone-like morphology.②Cell growth curve: The growth curve of co-cultured cells was identical with that of cells by routine culture method.③Cell proliferation: MTT detection revealed no significant difference in the proliferation of co-cultured cells and cells cultured by traditional method (P
