Objective To investigate the effects of glycyrrhizin on gene expression of transforming growth factor(TGF)-?signaling pathway of hepatic stellate cell(HSC)in mice by gene microarray tech- nique.Methods The HSCs were isolated from mice and cultured in vitro.Then the mice were divided into control group,TGF-?_1 group(5 ng/ml) or TGF-?_1(5 ng/ml)combined with glycyrrhizin(100?mol/L) group.The cells were collected after 10 hours to extract RNA.A cDNA microarray(GEArray~(TM) Q) targeting TGF-?/BMP signal transduction was used to screen the genes which showed significant changes in expression of TGF-?pathway of HSC by glycyrrhizin.Results The microarray analysis showed that 16 genes(16.7%),such as Smad2,Smad3,Smad7,CoL3A1,CoL1A2,and PAI-1,were upregulated by TGF-?_1 and then down-regulated by glycyrrhizin.Five genes(5.2%)(including BMP7,IGFbp3 and etc.)downregulated by TGF-?_1,were then up-regulated by glycyrrhizin.Finally,2 genes upregulated by TGF-?_1 were then up-regulated predominantly by glycyrrhizin in HSC(T?R2,betaglycan).Changes in some genes,such as Smad2 Smad3,Smad7,were further confirmed to be coincided with cDNA microarray by semi-quantitative RT-PCR.Conclusions The anti-fibrosis mechanisms of glycyrrhizin may be through to interference of TGF-?signaling pathway,decrease the synthesis and increase the degradation of collagen.

Objective To investigate the pathogens of acute respiratory infection of children.Methods A total of 159 children with acute respiratory infection who were hospitalized in our department from August 2005 to January 2006 were involved in this study.The serum IgM antibody of 18 pathogens were detected by indirect immunofluorescence test.The 18 pathogens included respiratory syncytial virus(RSV),adenovirus(ADV),influenza A(H1N1,H3N2)and B viruses,parainfluenza viruses(PIV) type 1,2,3 and 4,coxsackie virus B1(CBV1),coxsackie virus A7(CAV7),echovirus(ECHO7),haemophilus influenzae(HI),klebsiella pneumoniae(KP),bordetella pertussis(BP),bordetella parapertussis(BPP) and legionella pneumophila serotype 1 and 12.Results The evidence of specific IgM was obtained in 103 of 159 patients(64.78%).Influenza A was found in 66 cases(64.08%),influenza B in 49 cases(47.57%),enterovirus in 26 cases(25.24%),RSV in 18 cases(17.48%),PIV in 11 cases(10.68%),and co-infection in 66 cases(64.08%),1/ 3 of them were co-infected with influenza A and B.Conclusions Viruses are the most common agents of acute respiratory infection.Influenza virus is predominant among them.

Background and Objective Keshan disease is clinically characterized as a dilated eardiomyopathy. We analyze the prevalence trend during last decade of hypertension and Keshan-disease in Yangzhuang village which was a Keshan-disease epidemic area.Method The survey including medical history,blood pressure and ECG were carried out every two years during the follow up 13 years.Results During follow up period,the total detection rate(hypertension:13.4 % vs Keshan-disease:10.7 %,?~2=8.555,P=0.002)and the accumulative rate of hypertension were higher than those of Keshan-disease,which was on the contrary to that before 1993,when increasing rate of Keshan-disease was higher than hypertension.Furthermore,the accumulative increasing rate of hypertension was 240.0%,which was higher than the national average level during corresponding period with no significant differences between female and male.Conclusion The detection rate of hypertension in Keshan disease epidemic area was higher than the average rate nation-wide.Whether the hypertension prevalence was re- lated to Keshan-disease needs further investigation.

OBJECTIVETo compare mid-term clinical outcomes between amputation and limb salvage in treating severe open tibial fractures with type Gustilo III B, III C.

METHODSFrom July 2007 to June 2010,68 patients with severe open tibial fractures with type Gustilo III B, III C treated by amputation and limb salvage were retrospectively analyzed. In amputation group, there were 26 males and 12 females with an average age of (44.9±16.3) years old; and 21 cases were type Gustilo (III B, 17 cases were Gustilo III C; amputation were performed in accordance with soft tissue injury degree of shank, fracture types and surgical exploration. In limb salvageg group, there were 21 males and 9 females with an average age of (43.5±14.7) years old; and 23 cases were type Gustilo III B, 7 cases were Gustilo III C; the method of internal fixation and and wound healing were performed in accordance with patients's specific condition. Operative time, blood loss, hospital stay and postoperative infection was compared between two groups; time of loading and rate of return to work was compared; VAS scoring was used to evaluate condition of pain; SF-36 health queationaire was used to assess postoperative life quality.

RESULTSTotally 60 patients were followed up (33 cases in amputation group and 27 cases in limb salvage group) with an average time of 49.1 months. Operative time, blood loss, hospital stay and postoperative infection in amputation and limb salvage group respectively was (109.0±25.7) min, (245.0±58.6) min; (168.0±49.0) ml, (311.0±137.0) ml; (13.8±2.7) d, (28.8±13.1) d; 7.9%, 36.7%. At the final following-up, there was no significance meaning between two groups in VAS scoring and rate of return to work, but time of loading in amputation group was shorter than that of in limb salvage group. Physiological function in amputation group was better than limb salvage group, while body pain was worse; and there was no signicance meaning in psychological health between two groups.

CONCLUSIONAmputation and limb salvage both can treat severe open tibial fractures, and mid-term clinical outcomes between two groups has equivalent efficacy.

OBJECTIVETo investigate the feasibility of using percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation for treatment of the Barton fracture of aged people.

METHODSFrom June 2011 to May 2013, 91 patients with closed and fresh Barton fracture were analyzed retrospectively which information was complete. According to different methods these patients were divided into three groups: 33 patients in group A were treated by simplex fixation of gypsum or splint after manipulative reduction, including 20 males and 13 females with an average age of (63.27 ± 5.83) years old; 35 patients in group B were treated by percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation, including 23 males and 12 females with an average age of (64.25 ± 4.53) years old; 23 patients in group C were treated by open reduction and internal fixation including 15 males and 8 females with an average age of (64.04 ± 4.83) years old.

RESULTSAll the patients were followed up for 10 to 16 months with an average of 12 months by the method of recheckging in outpatient clinic. According Dienst scoring system: in group A, the result was excellent in 15 cases, good in 7 cases, fair in 11 cases; in group B, excellent in 25 cases, good in 6 cases, fair in 4 cases; in group C, excellent in 16 cases, good in 5 cases, fair in 2 cases. The excellent and good rate of group C was better than that of group B and A, further more group B is better than group A. According to X- ray standard, in group A, 26 patients were acceptable, 7 patients were unacceptable; in group B,28 patients were acceptable, 7 patients were uacceptable; in group C, 19 patients were acceptable,4 patients were unacceptable; there were no statistical significant difference (P > 0.05). There were 18 patients with emerging recrispation in group A, 10 patients in group B, 6 patients in group C, the result of group B and C was better than that of group A, and there was no statistically significant between group B and C (P > 0.05).

CONCLUSIONUsing percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation for treatment of the Barton fracture of aged people is an effective method, it has advantages of micro-invasived, reliable fixation, less complication, not need to fix wrist joint and early functional exercise.
