Objective: To explore the value of Hisense computer-assisted surgical systems (CAS) for precise surgery of pediatric solid pseudopapillary tumor. Methods: A total of 5 cases with pancreatic solid pseudopapi-llary tumor who were admitted at the Affiliated Hospital of Qingdao University from June 2015 to September 2018 were adopting.Upper abdominal 64-slice dynamic enhanced computed tomography (CT) scan was performed.3D models were created by computer-assisted surgery systems.Based on 3D model, surgical planning, preoperative simulated tumor resection, intraoperative assisted guidance were performed.Operation time, intraoperative blood loss volume, blood transfusion rate were analyzed. Results: Hisense CAS three-dimensional reconstruction could clearly show the adjacent relationship between pancreas, tumor and peripheral vascular organs.According to the preoperative virtual resection, pancreatic tumor resection was more accurate.Postoperative pathological results were solid pseudopapillary tumor of the pancreas.Among them, 2 tumors were located in the head of the pancreas, 1 case was located in the pancreatic neck, and 2 cases in the tail of the pancreas.The operation time was 150-360 min, with an average of 279 min.The average intraoperative blood loss was 40 mL, of which the minimum amount of bleeding was 5 mL, and the blood transfusion rate was 40%(2/5 cases). Surgical tumor removal was achieved successfully in 5 cases.All children were followed up for 6 months to 3 years, and no recurrence or metastasis was observed. Conclusions Three-dimensional reconstruction of computer-assisted surgery system can clearly show the adjacent relationship between tumor and surroun-ding vascular organs, and help to make the best surgical plan before surgery to improve the accuracy and safety of the operation.

Objective: To understand the prevalence of attention deficit and hyperactivity disorder (ADHD) in children in China and provide scientific basis for early prevention and treatment of ADHD in children. Methods: A systematic literature retrieval was conducted by using CNKI, Wanfang data, CBM and VIP databases for the information about the prevalence of ADHD in children in China published from 1979 to 2017. Pubmed database was used to retrieve the literatures about ADHD prevalence in children in China published from 1946 to 2017. The quality of literature was evaluated based on the cross-sectional study criteria according to STROBE statement. Stata 12.0 was used for combined prevalence and subgroup analyses, including gender, regions, publication year, diagnostic criteria, sampling methods, and so on. Egger testing and the evaluation of funnel graph were used to evaluate the publication bias of these literatures, and sensitivity analysis was done by using different models and eliminating the influence of any one of these articles on combined effect value. Results: Twenty articles were included. The total sample size was 88 755, including 46 216 boys and 42 539 girls. The prevalence of ADHD in children in China was 5.6% (95%CI: 5.0%-6.3%). The prevalence was 7.7% (95%CI: 6.7%-8.8%) in boys and 3.4% (95%CI: 3.0%-3.8%) in girls, the difference was statistically significant (P<0.05). No statistically significance difference in the ADHD prevalence was observed between different regions publication years, diagnostic criteria and sampling methods. Conclusions: The prevalence of ADHD in children in China was high, and boys tended to have a higher prevalence compared with girls. Appropriate screening methods for early detection and intervention conduction of ADHD should be taken among children in China.

Objective: To estimate the association between high-sensitivity C-reactive protein (hs-CRP) and cardiovascular events as well as all-cause mortality events. Methods: During 2009- 2010, out of the 11 623 individuals, 1 000 participants aged 35-64 years, were recruited and divided into 12 age-groups, to have received a study on CVD risk factors. Information on the risk factors of cardiovascular diseases was also collected. Fasting blood sample was gathered for all the participants, with hs-CRP tested. Participants in 7 out of the 12 sites were followed, with 6.21 years (36 075 person-years) as the median follow-up period. Cardiovascular and all-cause mortality events were collected. A total of 6 177 participants had been followed after excluding participants who had baseline infections, or did not take hs-CRP test/physical examination at the baseline. Finally, 5 984 participants were included for analysis. Participants were categorized into three groups based on the hs-CRP (mg/L) values: <1, 1-3 and >3, respectively. Cox proportional hazards regression model was used to analyze the relationships between hs-CRP with cardiovascular events or all-cause mortality events, after adjusting for confounding factors. Results: Mean age of the participants was 50.2 years. The incidence rates of cardiovascular disease events were 3.6/1 000 person-years, 7.1/1 000 person-years,and 10.4/1 000 person-years among three groups and 3.0/1 000 person-years, 5.7/1 000 person-years, 9.1/1 000 person-years for all-cause mortality events, respectively. After adjusting for confounding factors, the hazard risks (HR) for cardiovascular events were 1.33 (95%CI: 0.95-1.84) in the hs-CRP 1-3 mg/L group and 1.76 (95%CI: 1.20-2.60) in the hs-CRP>3 mg/L group when comparing with the hs-CRP<1 mg/L group (trend test P=0.003). The HRs for all-cause mortality events were 1.76 (95%CI: 1.23-2.54) and 2.64 (95%CI: 1.74-4.01) (trend test P<0.001), respectively. Conclusion: Hs-CRP appeared an independent predictor for cardiovascular events and all-cause mortality events.

Objective: To investigate the changes of proportion on both consistent condom use and syphilis infection among low-fee female sex workers aged 35 and above (LFSW), in order to provide evidence for targeted intervention strategies. Methods: A total of six cities-Liuzhou city and Pingnan couty of Guigang city of Guangxi Zhuang Autonomous Region, Jinghong city of Xishuangbanna Dai autonomous prefecture and Dali city of Dali Bai autonomous prefecture of Yunnan province, Zhangjiajie city and Jianghua Yao autonomous county of Yongzhou city Hunan province were involved in this study, with 60 eligible participants needed in each city, estimated through a pre-study. The first cross-sectional survey was completed from October 2012 to January 2013. Face-to-face questionnaire interview was carried out to collect information on socio-demography, work-related information and condom use situation. Blood was collected for syphilis testing. The second cross-sectional survey was carried out from June to September, 2015 under the same procedure. Results: A total of 371 and 403 eligible participants were included in the first and second survey, respectively. When comparing the two surveys, we noticed that the average age showed a slight change, from 42.4 years to 43.8 years old (t=3.537, P<0.001) and the average price for every commercial sex exchange increased from 36.8 RMB to 49.5 RMB (t=11.961, P<0.001). In the first survey, 46.9% (174/371) of the participants had more than two years of experience working as LFSW, compared to 61.3% (247/403) in the second survey (χ(2)=16.125, P<0.001). Also, 46.9% (174/371) of the participants consistently used condoms with clients in the past month in the first survey versus 64.3% (259/403) (χ(2)=23.641, P<0.001) in the second one. Rates of syphilis infection were found from 15.9% (59/371) in the first survey reduced to 7.2% (29/403) in the second survey (χ(2)=14.533, P<0.001). Conclusion: Compared with the first survey, the proportion of consistent condoms use showed an increase. Although the proportion of syphilis infection decreased in the second survey, the scope did not meet the criteria on syphilis, set by the government. Targeted intervention strategies on condom promotion and syphilis control should be implemented consistently in this population.
