Objective To study the management of enterostomy in children.Methods The clinical data of 425 cases of enterostomy in children were analyzed retrospectively.Results The primary diseases of 425 cases underwent enterostomy included:intestinal perforation(119 cases),intestinal necrosis(36 cases),necrotizing enterocolitis(45 cases),congenital megacolon(61 cases),congenital anal atresia with rectourethral fistula(86 cases),and congenital anal atresia with rectovaginal fistula(78 cases).Among the 425 cases,159 cases underwent small bowel enterostomy and 266 cases had colostomy;single-stoma enterostomy was done in 225 cases,and double-stoma enterostomy in 197 cases.Follow-up was acquired in 389 patients,and all the stomas were closed successfully.The closure time of small bovvel enterostomy was 1-3 month(ayerage 1.87 months)later,and of colostomy was 3-12 month(averag 4.95 months)later.Conclusions When an enterostomy is to be adopted in pediatric surgery,a suitable time and enterostomal location should be chosen according to the state of illness.The timing of enterostomy closure is also very important.

Objective To study the correlation between the blood selenium level and glutathione peroxidase(GSH-Px)with the occurrence of gestational diabetes mellitus(GDM).Methods Among 1 360 pregnant women in our hospital from January 2011 to December 2012,68 cases GDM were diagnosed as GDM (observation group)and other 113 non-GDM pregnant women were ran-domly selected from these 1360 pregnant women as the control group.The serum selenium level and GSH-Px activity were com-pared between the two groups.Results The selenium level and GSH-Px activity in the control group were higher than those in the observation group.The selenium level was (3.07±0.51)mmol/L in the control group and (2.06±0.41)mmol/L in the observa-tion group,respectively;the GSH-Px activity was (197.23±18.73)U in the control group and (151.35±19.67)U in the observa-tion group,the differences between the two groups were statistically significant (P <0.05).Conclusion The decrease of serum se-lenium level and GSH-Px activity may be one of the pathogenic causes of GDM.

Objective To investigate the effect of α-keto acid combined with low protein diet on kidney function, calcium-phosphorus metabolism and adenosine deaminase activity in malnourished patients with long term peritoneal dialysis.Methods Forty-six cases malnourished patients with long term peritoneal dialysis were selected from May 2013 to August 2014 in the hospital and divided into two groups.The control group (n=23) were treated by conventional therapy, acceptable daily intake of protein 1.2 g/(kg? d).The experiment group (n=23) were treated by α-keto acid combined with low protein diet, acceptable daily intake of protein 0.8 g/(kg? d).Two groups were treated for three months.Serum calcium, phosphorus, nutritional status assessment, adenosine deaminase activity and renal function were observed and compared after treatment.ResuIts After twelve months ’ treatment, compared with control group, serum creatinine, blood urea nitrogen, serum uric acid of experiment group were lower ( P<0.05); serum calcium level was higher (P<0.05), serum phosphorus level was lower (P<0.05);ADA activity and white blood cell count were lower (P<0.05). The incidence of malnutrition rate had no significant difference between two groups(χ2 =3.136,P>0.05).ConcIusion α-keto acid combined with low protein diet could effectively increase serum calcium level, reduce serum phosphorus level, ADA activity and WBC count, and improve nutritional status in long-term peritoneal dialysis patients, which has important significance.

ObjectiveTo explore the characteristics of phonological encoding of Chinese disyllabic compound words in patients with mild cognition impairment(MCI). Methods10 patients with MCI and 10 normal controls who matched with the age, gender, level of education and handedness performed homophone judgment task. In this task, a picture with a disyllabic compound name was presented, after 100 ms of the presentation there would be a Chinese character below the picture. Subjects were asked to judge whether one of the morpheme in the picture name was homophonic to the character. The reaction time and error ratio were analyzed statistically. ResultsIn the normal controls, the reaction time for the second constituents was shorter than that for the first constituents, while there were no difference between the first and second constituents reaction time in MCI patients. The error ratio of the first and second constituents showed no difference in normal controls, but MCI patients made more error rate for the first constituents. ConclusionAs the heathy elderly,the MCI patients have same pattern in phonological coding of Chinese disyllabic compound words, but much slower in activation speed, indicating the impairment of semantic memory and phonological activation in patients with MCI.

BACKGROUND: Apatite-wollastonite containing glass-ceramic (AWGC) is a kind of good bone repairing materials with excellent bioactivity, which is prepared by traditional melting process.OBJECTIVE: To observe AWGC prepared with sol-gel method and its bioactivity.DESIGN: Design experiment of materials process and in vitro bioactivity experiment.SETTING: College of materials science and Engineering of Sichuan University.MATERIALS: AWGC.METHODS: This experiment was conducted at the laboratory of College of Materials Science and Engineering of Sichuan University between August 2002 and May 2003. AWGC was prepared from sol-gel and followed by heattreating process. Bioactivity was investigated in vitro by immersing in the simulate body fluid (SBF) at 37 ℃ for 7 days .

Tangcao pill is commonly applied in adjuvant and even alternative therapy for patients with AIDS. However, the herb contains complex ingredients, but with unknown effect against anti-HIV drug and unknown function. Because CYP450 emzyme is the main metabolic enzymes of the drug, it is of important significance to study the regulation of CYP450 enzymes before and after the combined administration of Tangcao pill and EFV. Proteomics, due to its high throughout and high sensitivity, has been widely applied in CYP450 enzyme study. In this paper, liver microsomes were separated through differential centrifugation. Their proteins were separated through SDS-PAGE. The three protein bands that CYP450 enzymes were located were cut and identified by liquid chromatography tandem mass spectrometry. Totally 16 CYP450 isoenzymes were identified. Furthermore, in order to make a quantitative analysis on the effect of tang herb on CYP450 emzyme, the multiple reaction monitoring (MRM) technology based on MS was adopted. The CYP2C11 was selected based on the results of the mass spectrum identification of proteins. The characteristic polypeptides were obtained through searching Expasy blast database. The m/z of the fragment ions was less than 800. In the paper, the m/z of ion pairs of CYP2C11 were 711.5/232.1, 711.5/319.2, 711.5/466.2 and 711.5/595.3, and the m/z of ESAT-6 (internal standard, IS) were 735.5/215.3, 735.5/389.3, 735.5/460.3 and 735.5/524.3. The relative peak (analyte/IS) area was adopted for the relative quantitative analysis. Compared with the EFV single administration group, the EFV and Tangcao pill combined administration group showed a 1.6-fold increase in CYP2C11. The results of the paper indicated that Tangcao pill may affect drug metabolism by regulating metabolic enzymes such as CYP2C11, but the specific mechanism still unknown.
