Objective To observe the effect of Tangluotong Decoction(Decoctions of removing obstruction of meridians for treating diabetes)based on the principle of reinforcing kidney,activating blood and removing obstruction of meridians on the early diabetic nephropathy(DN)patients.Methods Totally 68 DN patients were randomized into two groups.In addition to the routine treatment for diabetes,the treatment group(38 patients)was administered Tangluotong Decoction while the control group(30 patients)was giv- en Lossartan Potassium Tablets.The clinical symptoms and signs and lab indices before and after treatment were observed.Results The comprehensive total effective rate of the treatment group was 89.47% while that of control group was 60.00%,the difference was significant(P

Objective To investigate the effect of penehyclidine (PHCD) pretreatment on Toll-like receptor 4 (TLR4) mRNA expression in the lung following acute lung injury (ALI) induced by hemorrhagic shock in rats. Methods Forty healthy SD rats of both sexes weighing 200-250 g were randomly divided into 5 groups( n = 8 each): group Ⅰ sham operation (group S); group Ⅱ ALI (group ALI); group Ⅲ, Ⅴ, PHCD 0.3,1.0, 3.0 mg/kg were given iv respectively at 30 min before hemorrhagic shock (P1-3). Hemorrhagic shock was induced by exsanguinations. MAP was maintained at 35-45 mm Hg for 60 min. The animals were killed at 4 h after resuscitation. Their lungs were removed for microscopic examination, W/D lung weight ratio and determination of TLR4 mRNA expression in the lung tissue (by RT-PCR). NF-κB p65 protein expression in the lung tissue was determined (by immuno-histochemical staining). Results Hemorrhagic shock significantly increased TLR4 mRNA and NF-κB p65 protein expression in the lung tissue and W/D lung weight ratio. Pretreatment with PHCD 1.0 or 3.0 mg/kg significantly inhibited hemorrhagic shock-induced increase in TLR4 mRNA and NF-κB p65 protein expression in the lung and W/D lung weight ratio. The lung injury was significantly ameliorated in group P2,3 as compared to group ALI. Conclusion PHCD pretreatment can attenuate ALI induced by hemorrhagic shock through down-regulation of TLR4 mRNA expression and decreasing NF-κB activity in the lung.

Objective To explore the puberty and height development in childern with congenital adrenal hyperplasia(CAH) due to 21-hydroxylase deficiency(21-OHD) with the simple virilizing(SV) form.Methods Patients of SV 21-OHD,diagnosed and treated in Tianjin Children's Hospital from Jan.1970 to Jan.2008,were treated with cortisone acetate or hydrocortisone after diagnosed,and blood investigations were performed as part of monitoring,and dosages were adjusted accordingly to obtain normal growth velocity and slow bone age(BA) development.Gonadotropin-releasing hormone agonist(Gn-RHa) was given after the appearance of central precocious puberty(CPP).Forty-one patients(18 females,23 males) had achieved final height before Dec.31st 2008,and their puberty and height development were analyzed in this longitudinal study by contrast the ages and statures of obtaining final height(FH),chronological age(CA) and BA of G2/B2 stage,duration from G2/B2 stage to obtain FH and stature development of different gender during this period and the influences of compliancy on the ages and statures of obtaining FH were contrasted.Results With regarding to the age of testicular volume ≥4 mL,78.26% boys were before 9 years old.As far as the age of breast development was concerned,38.89% girls were before 8 year old and 66.67% menarche occurred before 10 year old.The differences between the duration and stature development of the period from the state of G2/B2 to skeletal maturation of different gender were significant (Pa

Objective To analyze rate of and reasons for not undertaking insulin pump therapy in children with type 1 diabetes(T1DM) and explore potential countermeasures.Methods Two hundred and seventy-eight persons of T1DM,diagnosed in Tianjin Children′s Hospital from Jan.2000 to Dec.2008,were assigned to fill in a questionnaire on T1DM and insulin pump therapy.Reasons for different compliances were analyzed and strategies were explored.Results Eighty-five point twenty-five percent of the children(237 persons) undertook the therapy and 14.75%(41 persons) refused.In the group of younger than 3 years,58.33%(21 persons)accepted the therapy,while in the group of older than 3 years,89.26%(216 persons) undertook it,consequently there was statistically significant difference(?2=23.83,P

A bacterium that contains a chitin deacetylase has been isolated from ocean soil. It has been identified Baciluus .The best suitable condition of producing this enzyme is that pH is 4.0,35℃,and the incubate time is 80 hours in the present of Ca 2+ as well as having no chitosan. The best temperature of this enzyme when it acts is 40℃～50℃ and the best pH range is 4.5～5.0.

The transesterification reaction conditions of lard with methyl acetate with combined use of immobilized lipases as catalysts were conducted. Initially, according to single factorial experiments, the studies on Lipozyme TL IM and Novozym 435 respectively catalyzed transesterification of lard showed that the optimal parameters of transesterification reaction were: the molar ratio of methyl acetate to oil of 14∶1, 40% enzyme added based on oil weight, temperature 50℃. Combined use of Lipozyme TL IM and Novozym 435 was proposed further to improve the catalytic performance by the response surface method (RSM). Herein, a 5-level-3-factor central composite rotated design was employed to evaluate the effects of lipase loading, the proportion of the two lipases and amount of methyl acetate. The optimum conditions were as followings: 40% lipase loading based on oil weight, 50%/50% the proportion of lipases (Novozym 435/Lipozyme TL IM), and the molar ratio of methyl acetate to oil of 14∶1. And under the optimal conditions, the highest biodiesel yield of 97.6% could be attained, which was higher than the biodiesel yield with each single one of the two lipases. The results suggested that the technics of combined use of certain immobilized lipases catalyzed transesterification reaction of lard for biodiesel production with methyl acetate as the acyl acceptor could raise the FAME yield and save the production cost.

Objective To explore the risk factors for inguinal hernia in children.Methods A 1:1 matched case-control study which based on hospital group data was carried out.201 cases aged 0～6 years with inguinal hernia and controls were enrolled,and their parents were investigated with questionaire.Conditional logistic regression model was used for single factor and multivariate factoranalysistoestimateoddsratios(OR) and the 95% eonfidence interval(95% CI).Results Inguinal hernia was related to ehildren ' s constipation(0R=3.520,95%CI:1.238~10.015),children's cry(OR=6.532,95%CI:2.651~16.091),mother ate pickles(OR=2.529, 95%CI:1.271~5.031) and maternal anemia(OR=6.809,95%CI:2.530～18.322) during the period of one month before pregnancy and the first 3 months of gestation,the children's family history of inguinal hernia(OR=I 1.250,95%CI:4.766～26.553).Conclusion Children's constipation,children's cry,maternal anemia and eating pickles during the period of one month before pregnancy and the first 3 months of gestation,children ' s family history of inguinal hernia are the risk factors for children' s inguinal hernia.

Objective To explore the diangostic value of serumhigh sensitive C-reaction prtein (hsCRP) serum amyloid a (SAA) and C-reaction protein (CRP) in patients who had HBV hepatopathy.Method 127 subjects with hepatopathy caused by HBV infection and 50 control subjects were incorporated in this research,and 47 cases with HBV hepatitis,35 cases with HBV cirrhosis and 45 cases with hepatic failure and SAA and CRP hsCRP of every sample was detected.Results ①Levels of CRP and hsCRP in cases were significantly higher than controls (Mann-Whitney U test,Z=-2.792,-8.458,P＜0.01).②The hsCRP levels in the three different groups of cases were different (Kruskal-Wallis test,x2=11.625,P＜ 0.01).③The hsCRP level of group 2 and 3 was significantly higher than group 1 in the hepatic damage groups (Mann-Whitney U test,Z=-2.849,-2.902,P＜0.01).④But the level of SAA had no statistically significant in any group.⑤The seropositivity of hsCRP in cases group was 76.29 ％ and it was higher than CRP (11.34 ％) and SAA(26.80 ％).Conclusion The diangosic value of CRP and hsCRP may better than SAA in the patients who got HBV hepatic damage which maybe caused by detection method as hsCRP is better than CRP.
