Objective To explore diagnosisand treatment of intestinal obstruction by foodballs in children. Methods The clinical datum of 21 cases of intestinal obstruction by foodballs in children were retrospectively ana- lyzed.Results While admission,only 2 cases could provide the history of having eaten foodballs wholly which could not be digested easily.The characteristics of clinical manifestation were intestinal obstruction completely or incom- pletely.All 21 cases had been treated conservatively first,only one case was successful and the other 20 cases had been cured by surgery afterwords.Conclusion There is no specific feature in clinical manifestations of intestinal ob- struction by foodballs in children,so it is difficult to make the diagnosis,but it must be considered suspicious especial- ly for those from rural area and with simple intestinal obstruction with reasons not known yet.If conservative therapy is failure in a short period,an operation should be done immediately.During operation,it is necessary to examine the whole digestive system thoroughly.

Objective To study the effect of mini percutaneous nephrolithotripsy (MPCNL) for non-nephredema kidney calculi. Methods A total of 47 patients with non-nephredema kidney calculi were enrolled in this study. Physiological saline solution was infused into the kidney through a ureteral catheter to induce hydronephrosis. C-arm X-ray machine was employed in percutaneous puncture and Wolf EMS was used to smash the calculi. Results The mean operation time was (120?35) min.The calculi were removed through one passage in 38 cases,through two passages in 6, and three passages in 3. Among the 47 patients, the MPCNL was performed once in 35, and twice in 12. The stone-free rate was 83.0% (39/47) and final stone-free rate was 93.6% (44/47). No complications were noted in all the patients. Conclusions Highly skilled technique is necessary in MPCNL for non-nephredema kidney calculi. The MPCNL is a safe, minimally invasive, and effective method. By using MPCNL, patients have less trauma, lower rate of calculi remaining, and quick recovery. As long as the surgeons are familiar with the technique of MPCNL and the anatomy of non-nephredema kidney, the therapeutic outcome can be as good as that in the patients with nephredema renal calculi.

Objective This study investigates the effect of collectivism-individualism on parenting goals of middle school students' parents. Methods COLINDEX and Kohn's Parental Values Survey were used. 378 parents participated in the study. Results Fathers had higher score(3.23±0.73) on individualism than do mothers (3.05±0.44,F(1,359)=5.25,P <0.05);and highly educated (college or above) parents had higher scores(4.00±0.86) than do those with less education(for senior high school:3.91±0.81; junior high school or below:3.83±0.97,F(2,363)=4.72,P <0.01). Regression analysis indicated that collectivism had significant effects on goals of "take responsibilities and adapt to environment" ( P <0.01) and "conform to norm and obey parent" ( P <0.01). Both collectivism and individualism had significant effects on goal of "explore and be enterprising" ( P <0.05;P <0.01). Conclusion Parents with high collectivistic value expected their children to assume responsibilities,to adapt to the society,to adhere to norms and to obey authority. However,parents with high individualistic value encouraged their children to be independent and enterprising.

Objective To explore the construct validity of collectivism and individualism scale( COLINDEX) and the reliability and construct validity of its Chinese revision;and to study the development of middle school students' value. Methods The revised scale was used and 5875 middle school students were tested. Resuits Two-factor model of COLENDEX was not substantiated by data,while three factors were abstracted by EFA and confirmed subsequently by CFA. Four factors were abstracted from the Chinese revision of COLINDEX, and four-factor model was confirmed. The Cronbach's alpha coefficients of the total scale (0.90) and four sub-scales (0.84,0.76,0.84 and 0.74 )were all significantly high. MANOVA was performed to detect gender and grade differences of means in the four dimensions of the revised scale. The main effects of gender and grade reached the significant level; however, interaction between them did not. Conclusion Collectivism and individualism, two dimensions of Chinese middle school students' value, were not mutually independent. The revised version of COLINDEX was qualified to be used in further research. The grades on collectivistic items of middle school students were higher than those on individualistic items.

Objective To study the method, advantage and shortcoming of mini-laparoscopic treatment for indirect inguinal hemia in children. Methods 136 cases with indirect inguinal hernia(right:75cases,left:44 cases,bilateral:17 cases) had been treated by high ligation with mini-laparoscopy. Results The mean operation time was 10 mmin for unilateral hernia and 23 mmin for bilateral hernia. Among 119 cases with unilateral hernia,38 cases had been found with contralateral latent hernia. The mean of postoperative inhospital stay were about 1 ～ 2 day(s). All patients had been followed-up for 3 ～ 12 months,there were only 2 cases recurrence found but no complications was detected.Conclusion Mini-laparoscopic high ligation for indirect inguinal hernia in children is a single, safe, satisfactory, effective,and minimally invasive surgical method.

Purpose To investigate the diagnostic value of multi-slice spiral CT (MSCT) enhanced scanning in borderline and invasive ovarian tumor,and to provide valuable image evidence for clinical treatment.Materials and Methods One hundred and one patients with pathological-confirmed borderline and invasive ovarian tumor in the First Affiliated Hospital of Jinzhou Medical University from October 2012 to October 2016 were selected,and the preoperative abdominal MSCT enhanced imaging,clinical and pathological data were retrospectively analyzed.The MSCT imaging was observed,and the prediction model of MSCT differentiating borderline and invasive ovarian tumor was established.Results The differences of onset age,menopausal status,tumor solid components,maximum diameter,septa and margin were all statistically significant between borderline and invasive ovarian tumor groups (P＜0.05).The prediction model of MSCT differentiating borderline and invasive ovarian tumor was established using multivariate Logistic regression,on the basis of following variables (OR＞l,P＜0.05):tumor size,solid components and septa.The sensitivity and specificity of the prediction model were respectively 81.3％ (95％ CI:0.622-1.000) and 85.7％ (95％ CI:0.741-0.973) in predicting borderline ovarian tumor for patients before menopause,and respectively 92.1％ (95％ CI:0.835-1.000) and 91.7％ (95％ CI:0.761-1.000) for those after menopause.Conclusion MSCT enhanced scanning is helpful to differential diagnose of borderline and invasive ovarian tumor,and it has important significance for clinical treatment and prognosis evaluation.

Objective To observe the effect of early mild hypothermia on the opening of tight junction of cerebral endothelial cells following traumatic brain injury in order to illustrate possible mechanism of low permeability of blood brain barrier (BBB) treated by mild hypothermia. Methods A total of 90 Wistar rats were randomly divided into normothermia control group (n=10),normothermia injury group (n=40) and mild hypothermia group (n=40). The opening state and its extent of tight junction were observed using lanthanum trace labeling with electron microscope. At the same time,water content of cerebral tissue at different phases in normothermia injury group and mild hypothermia group was measured by means of dry-wet weight and analyzed statistically. Results The tight junction was under preliminary opening three hours after trauma and reached the maximum opening within 24-48 hours after trauma,lasting for 72 hours in the normothermia injury group. However,slight opening appeared only in the mild hypothermia group. Water content of cerebral tissue in the mild hypothermia group lessened obviously in contrast to that in the normothermia injury group,with significant difference 3,24 and 72 hours after trauma ( P

Objective To explore the protective effects of 10-HDA combined with AA-2G on UVA-induced photodamage in fibroblasts. Methods The primary cultured human skin fibroblasts were divided into three groups: blank control group, UVA irradiation group and 10-HDA+AA-2G group. The cell viability and cellular senescent state were analyzed using CCK-8 and senescence associated-β-galactosidase (SA-β-gal) staining, respectively. Fluorometric assays were performed to detect the formation of reactive oxygen species (ROS) in the cells. Results Compared with those in control group, the cell viability was decreased (P < 0.05), and the SA-β-gal positive cells and ROS level were significantly increased (P<0.01 for both) in UVA-irradiated group. Compared with those in UVA-irradiated group, the cell viability was significantly increased (P < 0.01), and the SA-β-gal positive cells and ROS level were significantly reduced (P < 0.05, P < 0.01, respectively) in the 10-HDA combined with AA-2G group. Conclusion Fibroblasts treated with 10-HDA and AA-2G are significantly protected from UVA-induced cytotoxicity, cellular senescence and ROS, indicating that 10-HDA combined with AA-2G has photoprotective effects. Therefore, 10-HDA combined with AA-2G may be a potential combination for the prevention and treatment of skin photoaging.

In the future,anti-ship missiles(ASM) will be major weapons in the sea war.It is very important to handle the profile of the casualties aboard warships attacked by ASM for development of naval health service.The statistical result shows there is a greater chance of casualties but less chance of warships being sunken by ASM.Besides,medical staffs should pay more attention to the first aid for victims due to blast,burn,smoke inhalation and penetration while the danger of the sea water immersion should not be ignored.
