OBJECTIVETo compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.

METHODSFrom June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.

RESULTSAll patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONClose reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.

Objective To explore the state of the mental health and related factors of Zangzu undergraduates in inland.Methods Two inland typical universities were chosen,according to random whole-class sampling principle from different grades,and 370 Zangzu undergraduates in inland were tested with Symptom Checklist 90(SCL-90),Self-Esteem Scale(SES),Simplified Coping Style Questionnaire (SCSQ) and social support scales,and compared with norm and Hanzu undergraduates.Results The scores of the factors of compulsion,interpersonal relation sensitiveness,depression,anxiety,hostility of Zangzu undergraduates in inland in SCL-90 were higher than 2.The rate of their mental problems(the total average score was higher than 2) was 45.3％,among them the rate of mild mental problems was 42.0％,the rate of secondary mental problems was 3.3％,without undergraduates of serious mental problems.Scores of the 9 factors were higher than that of the norm,and differences were significant (P＜ 0.01).Scores of the 9 factors were higher than that of Hanzu undergraduates,and scores of somatization,compulsion,anxiety,hostility,terror were significantly higher than that of Hanzu undergraduates (P ＜0.01).Rate of their mild mental problems was significantly higher than that of Hanzu undergraduates(P＜0.01).Scores of their self-esteem and positive coping styles were lower than that of Hanzu undergraduates,and differences were significant (P =0.000).The negative coping styles and self-esteem could predict the state of mental health of Zangzu undergraduates in a great extent.Conclusion Zangzu undergraduates in inland have more mild mental problems,which are correlated with their self-esteem and coping styles.

BACKGROUND: Two-dimensional electrophoresis (2-DE) is precise and effective for the isolation and analysis of complex protein mixtures, has become one of valuable key techniques for proteome. Mice models were as research subjects to model human disease status, one of important methods for cardiovascular disease. The establishment and optimization of 2-DE for proteomes of mice myocardium will provide basis for heart disease.OBJECTIVE: To establish and optimize a stable technique of 2-DE for proteomic analysis of mice myocardium.DESIGN: Mice were used as research subjects, observational comparative study.SETTING: Department of Pathology, Nanfang Hospital Affiliated to Southern Medical University.PARTICIPANTS: The experiment was performed at the Department of Pathology, Nanfang Hospital Affiliated to Southern Medical University between February and September 2004. Totally 12 male BABL/c mice of 4-5 weeks without special-pathogen free with the body mass of 12-15 g were selected, which was provided by the Experimental Animal Center of Southern Medical University.METHODS: The mice were put to death by dislocation of cervical vertebra under drugged state to obtain heart. Various protein extraction method,loading sampling buffer, strip range of IPG, sampling volume of protein,staining method and so on were compared, analyzed, scanned and digilized,and then performing image analysis. Each link in the study was established and optimized.MAIN OUTCOME MEASURES: Resolution of protein and reproducibility of the trial.RESULTS: A method that was optimal for cardiac tissue can isolate about a total of 910 protein spots on pH 4-7 gel strips. 200 μg was fit for silver stain while 1000 μg was for Coomassie stains. It was found that in the myocardium of normal mice about (920±30) protein spots were obtained in 17 em pH 3-10 L gel strip, while around (880±30) were gained in the pH 4-7 L gel strip. The mean matching rate achieves to 86. 9%.CONCLUSION: The findings of the trial showed that 2-DE technique can be effectively applied for proteomics of myocardium of mice to regulate and optimize, and relatively stable separation method of myocardial protein was established.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.

OBJECTIVETo evaluate the feasibility of laparoscopic and endoscopic cooperative partial gastrectomy,a minimally invasive surgery, in treating gastric submucosa lesion.

METHODSWe retrospectively analyzed 63 patients [34 women and 29 men, aged (52.8±18.1) years (range:14 to 78 years)] who had undergone laparoscopic and endoscopic cooperative partial gastrectomy with preserving cardia and pylorus for gastric submucosal tumor in the past 6 years. All of the patients were followed up for 2-69 months (average 35 months). The clinicopathological data, surgical approaches, and follow-up results were analyzed.

RESULTSThe surgery was successfully performed in all these 63 patients, among whom 61 were assisted by endoscopy. The most common symptom was dyspepsia. The mean distance from the lesions locating at fundus or antrum to cardia or pylorus was(2.9±1.1)cm. The minimum distance from tumor edge to cardia was 1cm. The diseases included gastrointestinal stromal tumor (n=54), carcinoid tumors (n=3), ectopic pancreas (n=2), lipoma (n=2), and leiomyoma (n=2). The tumor size ranged from 0.8 to 8.2cm, with 44 lesions (69.8%) less than 2cm. Forty-five lesions(71.4%) were located at fundus, 12 (19.0%) at body, and 6 (9.6%) at antrum. No recurrence or death was noted during follow-up.

CONCLUSIONSLaparoscopic and endoscopic cooperative partial gastrectomy is feasible for treating gastric submucosal tumor. Endoscopy is useful for intraoperative localization and supporting, and therefore is especially helpful for preserving cardia and pylorus.

OBJECTIVETo evaluate the prognostic effects of neoadjuvant chemotherapy (NAC) in patients with local advanced gastric cancer.

METHODSWe retrospectively analyzed prognosis in 191 patients with advanced gastric cancer, of whom 71 were treated with NAC and 120 received surgery only between February 2007 and July 2013. Postoperative complication rate was recorded. Survival by clinicopathological features, pathological T and N stages, and histopathological tumor regression was retrospectively compared between the two groups.

RESULTSAccording to Response Evaluation Criteria in Solid Tumors, none of the 71 patients in the NAC followed by surgery group showed complete response, 36 showed partial response, 25 had stable disease, and 10 had progressive disease. The chemotherapy response rate was 50.7%; the disease control rate was 85.9%. Grade 3/4 adverse events were seen in less than 20% patients, with acceptable toxicities. No difference was found in the overall postoperative complication rates between the two groups (7 versus 22 cases, P=0.18). Median survival time was significantly different, at 54 months in the NAC combined with surgery group and 25 months in the surgery-only group (P=0.025).

CONCLUSIONIn patients with operable gastric adenocarcinomas, NAC can significantly improve overall survival without increasing surgical complications.

Human gut microbiota plays a key role in the development of obesity. Intestinal flora can regulate energy absorption and nutrition metabolism, increasing the energy harvesting from diet. Alteration of gut flora produces excessive lipopolysaccharide, which, when absorbed into the blood, can induce inflammatory reactions and promote the high-fat diet-associated obesity and metabolic syndrome. Intestinal flora increase visceral fat deposition by lowering the expression of Fiaf in intestinal mucosa. Different immune status also affects the intestinal flora.The gut microbiota is hypothesized to be an environmental factor that contributes to obesity; by interacting with factors such as host and diet, it adjusts the energy metabolism. Antibiotics or probiotics may alter the composition of intestinal microflora and improve the metabolic syndrome, and thus provides new treatment options.
