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 study the effect of Xuebijing, a Chinese traditional medicine injection, on the THP-1 cells challenged by endotoxin, and to explore whether it induces endotoxin tolerance. Methods The THP-1 cells were pretreated with Xuebijing in different concentrations (10, 25, 50 mg/mL) and times (4, 12, 24 hours), and then challenged by endotoxin. The level of TNF-α in culture supernatant was detected by ELISA assay, and the expression of TLR4 and IRAK-M mRNA were detected by Real time-PCR technique. Results There was no significant difference in TNF-α level among all the groups (pretreated with different concentrations of Xuebijing for different time) (P>0.05). Only in 50 mg/mL Xuebijing group, TLR4 mRNA was 1.547-fold increase in 24 h than in 4 h group (P<0.05). Only when pretreated for 24 h, IRAK-M mRNA was 1.349-fold increase in 50 mg/mL Xuebijing group than in control group (P<0.05). However,there was no significant difference among other groups (P>0.05). Conclusions Xuebijing can not block the release of TNF-α from the THP-1 cells challenged by endotoxin;and it does not induce endotoxin tolerance. When pretreated with high concentration of Xuebijing for long time, the expression of both TLR4 and IRAK-M mRNA is up-regulated, but its significance is not yet clear.

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.

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

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.
