Objective: To examine the developmental characteristics of the pupils' emotion display rules and its relationship to the peer acceptance. Methods: A sample of 157 pupils' emotion display rules and peer acceptance in third and fifth grades were tested by clinical interview and social nomination. Results: Third-graders compared to fifth-graders were more knowledgeable about expression regulation, and used more self-protective display rules. Girls were proposed more norm-maintenance display rules than boys. Urban children compared to country children were more knowledgeable about expression regulation, and used more prosocial display rules. Self-protective display rules can predict peer rejection. Conclusion: Pupils' emotion display rules have different developing characteristics, and can predict peer rejection to a certain extent. The development of display rules is beneficial to moderate children's expression regulation and social development.

0.05). Body weight, blood pressure, blood routine test and blood biochemical parameters did not change in the two groups. Only mild side reactions of aescin was found and there was no dropout in the study group, whereas 7 patients dropped out in the control group due to the intolerance for the pressure. Conclusion Aescin has similar efficacy and fewer side effects compared with the compression stocking method in the treatment of chronic venous insufficiency.

Objective:To analysis the appearances and to evaluate the diagnostic value of X-ray CT and MR imaging in osteoid osteoma.Methods:22 cases 19 females and 3 males of osteoid osteoma proved by surgical pathology and their X-ray,CT and MRI were reviewed.The ability of X-ray,CT and MRI to demonstrate the nidus and surrounding reaction were analyzed.Results:The nidus were appeared as round or oval shape and the diameter was less than 2 cm.It was fomd in 17 cases of X-ray film，22 CT and 20 of MRI .There were different degree of bone sclerosis,periosteal reaction and soft tissues or bone marrow edema around the nidus.The diagnostic accuracy was 77.3% for X-ray，100% for CT and 90.9% for MRI.Conclusion:Most of osteoid osteoma have the typical appearances and is no difficult to make diagnosis.CT scan is the most accuracy method to demonstrate the nidus.It is possible to make misdiagnosis only with X-ray or MRI for the case that the hidus not be demonstodted.

Objective To explore the method of Oncomelania hupensis snail surveillance in transmission?interrupted re?gions of schistosomiasis,so as to provide a new pattern for the surveillance of snail status in the transmission?interrupted areas. Methods In Dongtai County,north of Jiangsu Province where the transmission of schistosomiasis was interrupted,the surveil?lance of snail status was performed by means of the village?level general survey,village?level sampling survey,snail survey in key settings of township and county,and snail reporting by residents. In addition,quality?control snail sites were set up for quali?ty control. The effectiveness and cost of the four methods of snail surveillance was compared. Results A total of 163 079 set?tings and 22 785.62 hm2 were surveyed in Dongtai County from 2008 to 2013,and 89 residual snail breeding sites were found, with a snail area of 1.48 hm2. The patterns of village?level general survey,village?level sampling survey,and snail survey in key settings of township and county were employed for investigation of 94 550,45 033 and 23 496 settings,consisting of 57.98%, 27.61%and 14.41%of total settings,and 2,0 and 6 settings were found with snails,with 0.021/thousand,0,and 0.255/thou?sand detection rates of settings with snail breading sites,respectively. The pattern of snail survey in key settings of township and county was more effective than that of village?level survey to detect snail breeding sites(χ2 =19.158,P=0). The recovery rate of quality?control snail breeding sites was 52.56%,38.27%and 73.62%for the three patterns of snail survey,respectively,and the pattern of snail survey in key settings of township and county showed a higher quality for snail survey than that of village?lev?el survey(χ2 =111.597 and 85.991,both P=0). During the period from 2008 to 2013,289 person?times reported 279 sus?pected snail habitats and 1 501 living snails,and no Oncomelania snails were found. During the 6?year period,there were 1617.5,964.7 and 527.7 thousand RMB invested for village?level general survey,village?level sampling survey,and snail sur?vey in key settings of township and county,and the cost of snail survey per hm2 was 129.88,133.6 and 162.57 RMB/hm2,re?spectively. The cost of village?level general survey and snail survey in key settings of township and county to detect a snail?breed?ing site was 808 800 and 88 000 RMB,respectively(t=12.850,P=0.000),and the cost of snail survey in key settings of town?ship and county was 10.88%of that of village?level general survey. Conclusion The snail survey in key settings of township and county is a highly effective and high?quality method for snail surveillance,which may serve as a prior way for the surveil?lance of snail status in the transmission?interrupted areas of schistosomiasis.

To establish stable methods for detecting plasma endotoxin level and endotoxin inactivation capacity in a normal population and general surgical patients and evaluate their perioperative changes. 50 healthy people and 50 patients receiving gastrointestinal operation were enrolled, their plasma endotoxin levels and plasma endotoxin inactivation capacity were assayed. Our results showed that plasma endotoxin levels were 0.044 +/- 0.009 EU/ml in the normal population and 0.044 +/- 0.023 EU/ml in the preoperative patients. Endotoxin level peaked 3 h after the operation (0.223 +/- 0.041 EU/ml), and then decreased rapidly on the first day after the operation (0.134 +/- 0.164 EU/ml). Endotoxin inactivation capacity also had the same time course as endotoxin level. Systemic inflammatory response syndrome and infection induced another elevation in the time course. It is concluded that establishing the endotoxin standard curve by using pyrogenic free water is better than by using plasma. Plasma endotoxin inactivation capacity can be used as an indirect indicator of postoperative immune depression. Plasma endotoxin level and endotoxin inactivation capacity peaked shortly after operation, indicating surgical stress is closely related with the changes.

Objective:To observe the efficacy of gemcitabine and oxaliplatin combined with targeted drug apatinib in the treatment of gallbladder cancer.Methods:The data of 82 patients with gallbladder cancer who were admitted to Haiyang People's Hospital, Yantaishan Hospital and Rongjun Hospital of Yantai City in Shandong Province from May 2017 to December 2018 were retrospectively analyzed. The patients were divided into control group and observation group according to the medication, with 41 cases in each group. Patients in the control group were treated with gemcitabine combined with oxaliplatin regimen (gemcitabine 1 000 mg/m 2 was injected intravenously for 30 minutes on the 1st and 8th day, and oxaliplatin 100 mg/m 2 was injected intravenously for 3 hours on the 1st day), the observation group was combined with apatinib mesylate 500 mg/d based on the treatment method of the control group. The treatment effect, serum tumor marker levels, adverse reactions and survival were compared between the two groups. Results:The disease control rate of the control group was 70.73% (29/41), which was significantly lower than that of the observation group [92.68% (38/41)] ( χ2 = 6.609, P < 0.05). After treatment, the levels of vascular endothelial growth factor (VEGF), carcinoembryonic antigen (CEA), soluble interleukin-2 receptor (sIL-2R) and Dickkopf-1 in the observation group were significantly lower than those in the observation group, and the differences were statistically significant ( t values were 6.011, 3.048, 4.444, and 4.514, all P < 0.05). The incidence of proteinuria and hand-foot syndrome in the observation group were significantly lower than those in the control group, and the differences were statistically significant ( χ2 values were 6.116 and 4.986, both P < 0.05). During the 1-year follow-up, 2 patients in the observation group died, and the survival rate was 95.13% (39/41); 8 patients in the control group died, and the survival rate was 80.49% (33/41). There was a statistical difference in the survival rate between the two groups ( χ2 = 4.100, P < 0.05). Conclusion:Gemcitabine and oxaliplatin combined with apatinib mesylate are effective in treating gallbladder cancer, which can effectively reduce serum tumor marker levels and improve the prognosis of gallbladder cancer patients.

To investigate the leukemogenic potential of PML-RARalpha fusion protein in vivo, hCG-PML-RARalpha transgene was constructed using molecular cloning technique and hCG-PML-RARalpha transgenic mice were generated. The genotype and phenotype of hCG-PML-RARalpha transgenic mice were analyzed by PCR, RT-PCR, morphology of peripheral blood and bone marrow cells, and pathological examination of spleen, liver and bone marrow. As a result, acute promyelocytic leukemia was developed in 3 hCG-PML-RARalpha transgenic mice in 1 - 5 months. The results demonstrated that PML-RARalpha fusion protein plays a crucial role in leukemogenesis.

OBJECTIVETo assess the accuracy of immunological fecal occult blood test (iFOBT) for detection of colorectal cancer (CRC).

METHODSA total of 1 197 studies published before June 2014 were selected from PubMed and Embase and 17 of which were finally included in this meta-analysis. A bivariate mixed-effects models was used for overall value merging and heterogeneity testing. In addition to the overall sensitivity and specificity, the analyses were also performed among certain subgroups, including a "colonoscopy group" (all were referred for colonoscopy diagnosis regardless screening results) and a "follow-up group" (only the screening positive were referred and all were then followed up), a qualitative group and a quantitative group (classified by the way of iFOBT result reading).

RESULTSA total of 161 502 subjects aged from 48 to 63 years were included in the analysis. IFOBT had an overall integrated sensitivity of 0.85 (95% CI: 0.79-0.89) (heterogeneity test: Q = 59.67, P < 0.001) and an overall integrated specificity of 0.93 (95% CI: 0.92-0.94) (heterogeneity test: Q = 1 722.53, P < 0.001) for detection of CRC. In the subgroup analysis, it was found that in the "colonoscopy group" and in the "follow-up group", the sensitivity were 0.81 (95%CI: 0.73-0.87) and 0.88 (95% CI: 0.81-0.92), respectively; the specificity were 0.92 (95% CI: 0.89-0.93) and 0.95 (95% CI: 0.94-0.96), respectively. It was also found that in the qualitative group and the quantitative group, the sensitivity were 0.84 (95% CI: 0.76-0.90) and 0.86 (95% CI: 0.78-0.92), respectively; the specificity were 0.94 (95% CI: 0.91-0.96) and 0.93 (95% CI: 0.91-0.94), respectively.

CONCLUSIONIFOBT had high overall sensitivity and specificity for detecting colorectal cancer.

Objective To compare the safety and clinical efficacy of transcatheter closure for ruptured aortic sinus aneurysm (RASA) with those of surgical treatment.Methods A total of 31 successive patients with RASA,who were treated in a single center during the period from October 2003 to May 2017,were enrolled in this study.Among them,11 patients received transcatheter closure therapy,their mean age was (36.64±10.87) years old;20 patients received surgical closure,their mean age was (28.90± 10.06) years old.The technical success rate,complications,residual shunt,operation time,hospitalization days,amount of blood transfusion,medical expenses,etc.were compared between the two groups.Results No statistically significant differences in age,sex and preoperative cardiac functional grading established by the Heart Disease Association of New York (NYHA) existed between the two groups (P＞0.05).The technical success rates in transcatheter closure group and surgical closure group were 100％ (11/11) and 95％ (19/20)respectively (P＞0.05).The amounts of blood transfusion in transcatheter closure group and surgical closure group were 0 ml and (427.25±331.36) ml respectively (P＜0.01).The time spent for operation in transcatheter closure group and surgical closure group was (60.00±00.00) min and (205.50±129.35) min respectively (P＜0.05).Days staying in intensive care unit (ICU) in transcatheter closure group and surgical closure group were 0 day and (1.50±0.61) days respectively (P＜0.01).The residual shunt rates in transcatheter closure group and surgical closure group were 9.09％ (1/11) and 10.00％ (2/20) respectively.None perioperative death occurred in both groups.No statistically significant differences in hospitalization days and in medical expenses existed between the two groups (P＞0.05).Conclusion Both transcatheter closure and surgical closure are safe and effective for the treatment of ruptured RASA,although transcatheter closure therapy has more advantageous in aspect of minimally-invasive management,operative time and length of hospital stay.For patients with a RASA which position is suitable for percutaneous interventional management,transcatheter closure therapy should be employed as a preferred therapy.
