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.

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.

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.

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 determine the difference of post-operative mortality between ORIF (open reduction internal fixation) and hip replacement for the treatment of intertrochanteric fracture in elderly by using survival analysis.

METHODSThe clinical data of 110 patients above 60 years old who underwent surgical treatment (ORIF or hip replacement) for the intertrochanteric fracture between April 2003 and May 2013 were retrospectively analyzed. Among the patients, 83 cases were treated with ORIF (ORIF group), there were 32 males and 51 females, aged from 61.44 to 98.75 years old with an average of (78.52 ± 7.98) years old; and 27 cases were treated with hip replacement (arthroplasty group), there were 8 males and 19 females, aged from 71.82 to 96.54 years old with an average of (79.99 ± 6.11) years old. A survival analysis was performed on the clinical data by using SPSS 110 software. The survival rate of 1-year,2-year, 5-year and the mean survival time for the total patients, the mortality rate of 1-year, 2-year in each group, the survival rate of 1-year, 2-year and mean survival time and survival curve in each group were included.

RESULTSAll wounds achieved primary healing and no deaths were found in stay hospital. All patients were followed up from 1 to 125 months with an average of (46.93 ± 29.53) months. Among all 110 cases, 31 were dead and 79 survived. The survival rate of 1-year, 2-year and 5-year was (90.7 ± 2.8)%, (82.5 ± 3.9)% and (57.6 ± 6.5)%, respectively,while the ensemble mean survival time was (84.137 ± 5.902) months. The mortality rate of 1-year, 2-year in ORIF group was 7.2% and 12.0%, respectively; and in arthroplasty group, there was 14.8% and 25.9%, respectively. There was no significant difference in mortality rate of 1-year and 2-year between two groups. According to the survival analysis of the ORIF group, the survival rate of 1-year, 2-year was (92.6 ± 2.9)%, and (85.8 ± 4.3)%, respectively, and the mean survival time was (87.508 ± 6.063) months. In arthroplasty group, the survival rate of 1-year, 2-year was (85.2 ± 6.8)% and (73.9 ± 8.5)%,and the mean survival time was (67.294 ± 11.180) months. There was significant difference in mean survival time between two groups (P < 0.05).

CONCLUSIONORIF can achieve a better postoperative survival compare with hip replacement in treating intertrochanteric fracture in elderly.

OBJECTIVETo study the change of the serum gastrin (GAS) and plasma motilin (MTL) levels as well as the gastric motility in gastric cancer patients after subtotal gastrectomy.

METHODSWe used radioimmunoassay method to detect the levels of serum GAS and plasma MTL in 39 healthy volunteers (control group) and 39 gastric cancer patients before and after gastrectomy (gastric cancer group). Electrogastrography (EGG) was measured at the same time points.

RESULTSThe levels of serum GAS and plasma MTL in gastric cancer group before operation were significantly higher than those in control group (P = 0.000), and the levels of serum GAS and plasma MTL in gastric cancer stage II patients were also significantly higher than those in stage III patients (P <0.05). The levels of serum GAS and plasma MTL in gastric cancer group significantly decreased on the first post-operative day (P = 0.000), but returned to the pre-operative levels on the seventh post-operative day. The incidence of the abnormity of gastric motility in gastric cancer group on the seventh post-operative day was significantly higher than the pre-operation incidence (89.7% vs. 43.6%; chi2 = 18.692, P <0.01).

CONCLUSIONSThe levels of serum GAS and plasma MTL transiently decreased in gastric cancer patients. Subtotal gastrectomy could affect the gastric motility in gastric cancer patients.

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.
