To evaluate the effects and safety of laparoscopic vertical banding gastroplasty (LVBG) in morbid obese subjects. The clinical data related to the metabolism of glucose, lipids and obesity in 26 obese Chinese patients with LVBG one year before and after the surgery were analyzed. The results showed that 1 year after LVBG, there was a reduction of 22.98?14.27kg in body weight, 9.31?5.13kg/m 2 in BMI, and a reduction of 47.19%?31.17% of body over-weight (EWL%) in these patients. BMI, waist, waist hip ratio, systolic blood pressure, fasting insulin, insulin resistance based on HOMA, triglyceride, cholesterol/HDL, ALT and blood creatine were decreased with reduction of body weight and BMI after LVBG. Changes in BMI and EWL% were significantly correlated with those of fasting insulin and insulin resistance. It is suggested that LVBG is effective and safe for reducing body weight and improving metabolism in the markedly obese patients.

Objective To study the influence and mechanism of hepatocyte growth factor (HGF) on myotube phenotype by myotube transdifferentiation induced by transforming growth factor-β1 (TGF-β1). Methods C2C12 cells were cultured in differentiation medium to induce myotubes formation. The cells were randomly devided into 3 groups. The control group without growth factor interruption. The induction group was supplemented with TGF-β1 (5 ng/mL) while the inhibition group was supplenmented with both TGF-β1 (5 ng/mL) and HGF (30 ng/mL). After 12 hours, the expressions of connective tissue growth factor (CTGF) protein in myotubes were detected by Western blot, the levels of CTGF mRNA were measured by RT-PCR. Results Compared to the control group, the protein and mRNA levels of CTGF significantly increased in TGF-β1 treated group , whereas the protein and mRNA levels of CTGF were significantly lower in inhibition group than those in induction group (P < 0.05). Conclusion HGF can inhibit the effect of TGF-β1 on the expression of CTGF in myotubes , which provides the evidences on the study of skeletal muscle cell transdifferentiation.

a greater impact,which could account for some pathophysiological changes caused by catch-up growth.

Objective To investigate the changes in cathepsin B (CatB) expression in acutely photodamaged human dermal fibroblasts (HDFs) and their significance.Methods HDFs were isolated from the foreskin of children,and subjected to primary culture and subculture.The fourth-to eighth-passage HDFs were used in the following experiment.HDFs were divided into two groups to receive irradiation with different doses of ultraviolet A (UVA) for different durations (acutely photodamaged group) or remain unirradiated (control group).Cell counting kit-8 (CCK8) assay was conducted to evaluate the proliferative activity of HDFs after irradiation with UVA at 5,10,15,20 and 25 J/cm2 respectively.Western blot and quantitative real-time reverse transcription PCR were performed to measure the protein and mRNA expressions of CatB respectively in HDFs at 24,48 and 72 hours after exposure to UVA at 10 J/cm2,and at 48 hours after exposure to UVA at 10,15,20 and 25 J/cm2.Statistical analysis was carried out by analysis of variance and least significant difference (LSD) test using the SPSS 13.0 software.Results UVA radiation induced a decrease in the proliferative activity of HDFs.When the dose of UVA was ≤ 10 J/cm2,the survival rate of HDFs maintained higher than 85％,and significant differences were observed in cell survival rate between unirradiated and irradiated HDFs at 24,48 and 72 hours (all P ＜ 0.05).Western blot showed that the gray value of CatB protein in the acutely photodamaged group irradiated with 10 J/cm2 UVA was significantly higher than that in the control group at 24 hours (0.76 ± 0.14 vs.0.35 ± 0.01,P ＜ 0.05),48 hours (1.34 ± 0.38 vs.0.45 ± 0.12,P＜ 0.05) and 72 hours (0.82 ± 0.09 vs.0.61 ± 0.06,P＜ 0.05).Increased mRNA expressions of CatB were also observed in the acutely photodamaged group compared with the control group at 24 hours (0.149 ± 0.009 vs.0.089 ± 0.015,P ＜ 0.05),48 hous (0.173 ± 0.009 vs.0.091 ± 0.010,P ＜ 0.05) and 72 hours (0.185 ± 0.158 vs.0.111 ± 0.017,P ＜ 0.05) after UVA radiation at 10 J/cm2.The gray value of CatB protein was 0.99 ± 0.07,1.49 ± 0.14,1.89 ± 0.08,2.07 ± 0.06 in HDFs at 48 hours after exposure to UVA of 10,15,20 and 25 J/cm2,respectively,significantly higher than that in the control group (0.60 ± 0.05,all P ＜ 0.05).Similarly,the mRNA expression of CatB was up-regulated in HDFs at 48 hours after UVA radiation at 10,15,20 and 25 J/cm2 compared with the unirradiated HDFs.Conclusion The protein and mRNA expressions of CatB are up-regulated in acutely photodamaged HDFs induced by UVA radiation.

Objective To compare open versus closed reduction in treatment of children with displaced femoral neck fracture whose reduction is delayed by more than 24 hours.Methods We retrospectively reviewed 51 children who had been treated at our department for femoral neck fracture between May 2005 and May 2012 after their reduction had been delayed for more than 24 hours.They were 37 boys and 14 girls,1.7 to 15.5 years of age (average,9.1 years).According to Delbet's classification,27 cases belonged to type Ⅱ,18 to type Ⅲ,and 6 to type Ⅳ.Of them,18 underwent closed reduction and 33 open reduction.Their complications were recorded in detail.Their therapeutic results were evaluated according to Ratliff's criteria and compared between the 2 methods of reduction.Results The 51 children were followed up for an average of 36.7 months (range,from 17 to 61 months).Anatomic reduction was achieved in 6 cases in the closed reduction group (33.3％) and 29 cases in the open reduction group (87.9％),respectively.All fractures healed after an average of 10.9 weeks (range,from 9 to 13 weeks),with one exception of nonunion in the closed reduction group.The incidence of femoral head necrosis in the closed reduction group (27.8％,5/18) was significantly higher than that in the open reduction group (15.2％,5/33) (P ＜ 0.05).According to the Ratliff's evaluation at the final follow-ups,the good to excellent rate in the closed reduction group(66.7％,12/18) was significantly lower than that in the open reduction group (84.8％,28/33) (P ＜0.05).Coxa vara occurred in 3 children in the closed reduction group but in none in the open reduction group.Conclusion Open reduction with internal fixation may lead to better outcomes than closed reduction in the treatment of children with displaced femoral neck fracture whose reduction is delayed by more than 24 hours,probably because open reduction can result in better reduction quality.

Objective To investigate the changes of blood lipid,endothelin(ET)and carbohydrate tolerance in simple obesity children.Methods Serum total cholesterol(TC),triglyeride(TG),low density lipoprotein(LDL),endothelin(ET) and oral glucose tolerance test(OGTT) of 436 cases(light obesity group 242,moderate obesity group 138,heavy obesity group 56) were detected respectively.Results The levels of TC,TG,LDL,ET and OGTT in 3 simple obesity groups were all higher than those in control group obviously and there were significant differences.The significant positive correlation between the obesity children serum lipids,ET and obese degrees were observed.Four insulin resistant children were found in heavy obesity group and none in other groups.Conclusions The levels of serum lipids and ET increases in obesity children and the OGTT decreases in some heavy obesity children.For preventing the obesity related health problems,the simple obesity children should be paid more attention to earlier.

Objective To construct recombinant prokaryotic plasmid DNA encoding mycobacterium tuberculosis (TB) heat shock protein 70 (HSP70) - Dnak gene obtained from pMT70, then purify its characterizes and the role of rHSP70 in tumor therapy. Methods Amplified by polymerase chain reaction (PCR) and with terminal modification, the Dnak gene was cloned into the vector with T7 promoter and was confirmed by restriction endonuclease digestion. So a new plasmid pMT70 - 3 was constructed and transformed in E. Coli. Strain BL21DE3. The engineering bacteria were induced by IPTG. Western-blot,natine-page and scanning were used to analyze the results. The human HSP70 were induced with peptides of lymphocytic leukemia cells of L1210 of mice in binding buffer which contain MgCl2 and ADP at 37 ℃ , then mice were given rHSP70 peptide - complex by SV injection twice at weekly intervals. Results The Dnak gene could be highly expressed in E. Coli as soluble protein. The expressing efficiency was 65% of the total cell protein and the soluble protein was 90% of the expressed protein. The rHSP70 - peptide complex could improve the immune protective function which had significant difference compared with controls (P

OBJECTIVE To summarize the clinical characteristics,diagnositic and therapeutic strategies of severe cytomegaloviral (CMV) pneumonia after kidney transplantation. METHODS To analyze retrospectively pertinent clinical information of 6 cases of severe cytomegaloviral pneumonia after kidney transplantation, including developing process of disease, clinical manifestation of pre-and post-hospitalization ,various assistant examination,therapeutic procedures and prognosis. RESULTS 6 cases had similar characters of episode as follows:CMV pneumonia occurred after 1～3 months after kidney transplantation. Major clinical symptoms included fever, coughing,few sputum without obvious manifestation of breathholding.Peripheral white blood cell was normal or less than normal range, serum CMVpp65 was finally positive during hospital stay. Radiological image of the lung presented inflammatory infiltration and obvious interstitial lesion after 7～10 days of fever, which went worse rapidly. Renal function descended with deterioration of pulmonary infection. All of patients had been treated with multiple antibiotics,glucocorticoid and mechanical ventilation, Etiological diagnosis of the 3th～6th cases were earlier than 1th～2th cases , the 3th～6th cases who finally survived were treated with longer and higher doses of antivirus and glucocorticoid, than 1th～2th cases who died of refractory hypoxemia and acute renal failure during hospital stay. CONCLUSIONS Severe cytomegaloviral pneumonia had similar clinical characteristics of episode. early diagnosis of etiology,continuous application of antivirus and glucocorticoid were crucial for Severe cytomegaloviral pneumonia after kidney transplantation.
