Objective To compare internet addiction disorders' family cohesion and their family educa-tion style, and to help prevent internet addiction disorder and interference treatment in families with internet addic-tion disorder. Methods Ninety adolescents with internet addiction disorder were investigated as the experimental group and one hundred normal adolescents as the control group. Questionnaire and in-depth interview was used to collect data,and the data was analyzed with SPSS 10.0. Results Average scores of control group were significant higher than those of experimental group in family cohesion ((51.75±8.86) vs (38.89±12.17), P<0.01). Av-erage scores of control group were significant higher than these of experimental group in family education style ((50.65±7.66) vs (41.44±10.84), P < 0.01). Average scores of experimental group were significant higher than those of control group in dissatisfaction of family cohesion and family education style ((20.87±4.66) vs (12.33±7.88); (23.30±11.06) vs (14.28±7.29), P < 0.01). Conclusion The adolescents with internet addiction disorder have low family cohesion and high dissatisfaction of family education style,wherefore during in-ternet addiction family intervention and prevention, it should pay particular attention to cultivating close and harmo-nious relations among families members. In aspect of family education, parents should pay special attention to chil-dren's healthy personality development, and guide their children to actively take part in social practice and train-ing.

In view of risk characteristics of surgical site infection,the risk factors of the infection were graded and classified while the risk indicators system and risk assessment matrix for surgical site infection were built,based on literature analysis,integrated use of documents analysis,Delphi method and risk quantification matrix.The study indicated that surgical skills of the surgeon and surgical time length are the most important risk factors,followed by insufficient maintenance of the operating room environment and poor baseline assessment of the patient.Risk control of surgical site infection needs to focus on these key factors,optimize utilization of resources and improve the prevention and control ability of surgical site infection.

Aim The changes of the levels of blood sugar and plasma insulin in obese woman pa-tients with insulin resistance and the effect of insulin intravenous infusion during oper-ation were observed. Methods 10 patients of normal weight(contrast group, group A)and 20 patients of obesity women(ASA grade Ⅰ- Ⅱ) undergoing selective surgerywere investigated. The patients of obesity were randomly divided into two groups(group B and C, respectively). Groups A and B liquids without glucose, and in group Ctransfuse liquids with glucose and insulin(4g glucose add 1U insulin) were transfusedduring operation. The levels of blood sugar and plasma insulin were measured beforeand after anesthesia, during operation(30min) and after operation respectively. ResultsThere was an insulin resistance phenomenon in patients with obesity. The levels ofblood sugar and plasma insulin in patients with obesity were remarkably higher thanthose in patients of normal weight. The levels of blood sugar and plasma insulin wereextremely raised after anesthesia and during operation. The levles of blood sugar wasinhibited as insulin was infused during operation, but no hypoglycemic reaction wasfound. Conclusion There are insulin resistance phenomenon in patients with obesity.Insulin infused during operation can prevent blood sugar rise and minimize glucosemetabolism turbulence.

The methods for aptamer selection have been modified and developed in recent years. Selection efficiency has been increased due to the improvement in separation of bound and unbound nucleic acids; applicability of aptamers has been improved due to the development of primer-free SELEX and the utilization of short oligonucleotide library; more research requirements have been satisfied due to the functional modifications of aptamer selection methods. All the methodological advances enhance the potential value of aptamers in basic researches and clinical applications.

Objective: To compare the efficacy difference between moxibustion at sensitized-acupoints and non-sensitized- acupoints using the same group of acupoints. Methods: A total of 139 patients with chronic superficial gastritis were divided into a sensitized acupoint group (102 cases) and a non-sensitized acupoint group (37 cases) based on whether acupoint sensitization occurred. The SPSS version 19.0 statistical software propensity score matching function was used to balance the baseline data between the groups. Finally, 29 pairs of matched patients were included, namely 29 cases in the sensitized acupoint group and 29 cases in the non-sensitized acupoint group. Both groups were treated with moxibustion therapy. The treatment lasted for 30 min per time, and was performed every other day for 8 weeks. Changes in the traditional Chinese medicine (TCM) symptom score and the short-form 36-item health survey (SF-36) score in both groups were observed before and after treatment, as well as the clinical efficacy. Results: The covariates of age, course of disease, TCM symptom score and SF-36 score in the two groups were balanced after matching (all P>0.05). After treatment, the total effective rate was 100.0％ in the sensitized acupoint group and 79.3％ in the non-sensitized acupoint group. The difference in the total effective rate between the two groups was statistically significant (P<0.01). After treatment and at the 4-week follow-up, the TCM symptom scores in the sensitized acupoint group were significantly lower than those in the non-sensitized acupoint group (all P<0.01); the SF-36 scores in the sensitized acupoint group were significantly higher than those in the non-sensitized acupoint group (all P<0.01). Conclusion: With the same group of acupoints, the sensitized acupoints have a better therapeutic effect and long-term efficacy than the non-sensitized acupoints in the treatment of chronic superficial gastritis.

0.05).Among the 26 pregnancies,there occurred one ectopic pregnancy and four cases of spontaneous abortion.In the 13 delivery cases,there were one premature delivery,two cases of premature rupture of the membrane,and ten cases of cesarean section.The sample height of the cone was less than 2.0 cm in the nine delivery cases,and the mean width of the cone was over 2.5 cm.Conclusion No evidence of secondary infertility caused by cervical conization was found.There was also no significant increase in the number of either premature delivery cases or low birth weight infants. The sample height of the cone might play a more important role in the pregnancy outcome than the width, which still needs to be further verified by larger studies.

Objective To study the inhibition effects of antibacterial proteins from Musca domestica larvae on JEC and A375 tumour cells. Methods Antibacterial proteins with concentrations of 0.02%,0.1%,0.5%,2.5% and 12.5% were supplied in the culture of JEC and A375 tumour cells in vitro.The cell cycles and apoptosis of JEC and A375 tumour cells were detected by flow cytometry,and the apoptosis index(AI) was measured.The morphology of apoptotic cells was observed with HE stainings and AO staining.The culture without antibacterial proteins was served as control. ResultsThe ratio of apoptosis index/proliferation index(AI/PI) of JEC cells increased with the concentration of antibacterial proteins.The PI and apoptosis rate of 2.5% antibacterial proteins group and 12.5% antibacterial proteins group significantly increased,and G0/G1 significantly decreased.For A375 cells,there were significant differences in G2/M, S,G0/G1,G2/M,AI/PI and PI between 12.5% antibacterial proteins group and control group(P
