Objectives To investigate the epidemiology of high-risk human papillomavirus (HPV) infection and the common genotypes in Liaocheng city, Shandong province, China, and to evaluate the application value of high risk HPV detection in cervical cytology with different pathological conditions.Methods A total of 19 707 permanent female residents in Liaocheng were recruited who were married or had sexual life, aged from 18 to 70 years old.They were screened for cervical cancer by thinprep liquid-based cytology test (TCT) from January 2013 to January 2014.The screen positive rate was 4.24 ％ (837/19 707), and 785 volunteers aged from 21 to 65 years old were recalled.The xMAP bead-based hybridization and flowcytometry analysis were used for genotyping.The data were analyzed by comparison and description.Results According to TCT, among 785 cases, there were 478 cases of atypical squamous epithelium of unknown significance (ASCUS) and atypical glandular epithelium of unknown significance (AGCUS), 175 cases of low-grade squamous intraepithelial lesion (LISL), 127 cases of high-grade squamous intraepithelial lesion (HSIL), 5 cases of squamous cell carcinoma (SCC) and adenocarcinoma (ACC).The positive rate of high-risk HPV was 62.8 ％ (493/785).The risk age of infection was 26-30 years old (87.7 ％, 71/81) and 51-55 years old (79.7 ％, 51/64), while a low risk one was found in patients older than 55 years old (28.6 ％, 14/54).The top five high-risk subtypes of HPV were HPV16 (21.5 ％, 169/785), HPV52 (12.2 ％, 96/785), HPV58 (9.8 ％, 77/785), HPV33 (9.7 ％, 76/785), HPV18 (7.5 ％, 59/785).Single infection accounted for 45.0 ％ (353/785), while multi-infection for 17.8 ％ (140/785).98 cases were infected by two subtypes, 37 cases by three subtypes, 2 cases by four subtypes, 2 cases by five subtypes and 1 case by six subtypes.Conclusions Compared with pure cervical TCT screening, high-risk HPV infection detection is an effective method for cervical cancer screening, which can improve the specificity of cervical cancer screening and reduce the omission diagnostic rate.In Liaocheng, HPV subtypes 16, 52, 58, 33, 18 and multi-infection are more prevalent.Women belonging to 26-30 or 51-55 years old are identified as high-risk population.Screening is important for this group to discover early cervical lesions.

Objective To explore the clinical and pathological features, diagnosis and treatment of eosinophilic cystitis in children. Method The clinical data of 7 patients with eosinophilic cystitis admitted from 2012 to 2016 were retrospectively analyzed, and the related literature were reviewed. Results The median age of the 7 patients was 9 years, and clinical manifestations were urgent urination, frequent micturition, odynuria, hematuria, abdominal pain and nocturnal enuresis. Ultrasonography and CT examination showed thickened bladder wall and space occupying lesions.All the 7 children received bladder biopsy, and pathology was consistent with eosinophilic cystitis. Six of them were cured after 2 months of drug therapy, and the other one was cured by repeated drug treatment for 1 year.All patients were followed up for 3 months to 4 years until the abnormal symptoms of voiding disappeared and the abnormal changes of bladder disappeared by imaging examination. Conclusion Eosinophilic cystitis in children is a benign lesion, having extremely similar clinical manifestations to bladder tumor. Without biopsy, the diagnosis of eosinophilic cystitis can also be made according to the clinical manifestation, laboratory examination and treatment effect. The treatment for this disease mainly includes hormone, antihistamine and anti-inflammatory drugs.

Objective To investigate the expression of human platelet antibodies(HPA)in children with immune thrombocytopenia(ITP)at different ages and their clinical significance in the treatment of ITP.Methods Two hundred eighty-eight cases of children who were newly diagnosed as primary ITP and detected with HPA from January 2013 to December 2015 in the First Affiliated Hospital of Zhengzhou University were selected.According to the HPA values,they were divided into <1:10 group,1:10 group and >1:10 group.According to their age,they were di-vided into <3-year-old group and ≥3-year-old group.Data were organized and the relationship among platelet antibody,age,gender and short-term efficiency of treatment was analyzed by using SPSS 21.0 statistical analysis soft-ware.Results In this study,there were 288 cases of children,with male to female ratio of about 1.3:1.0.As to the<3-year-old group and ≥ 3-year-old group,this difference of male to female ratio was statistically significant (respectively 1.93:1.00 and 1.02:1.00,χ2=6.629,P<0.05),and the difference of the HPA positive rate was statistically significant(respectively 72.5% and 59.5%,χ2=5.716,P<0.05);the HPA positive rate of boys and girls respectively was 65.9% and 63.7%,so their diffe-rence of the HPA positive rate was not statistically significant (χ2=0.143,P>0.05).Regarding the short-term efficiency,HPA in <1: 10 group,1: 10 group and >1:10 group was respectively 89.1%,89.1%,100.0%.Statistical analysis suggests:the short-term efficiency of <1:10 group and 1:10 group was basically the same(χ2=0.000,P>0.05);In comparison of <1:10 group with >1:10 group(χ2=4.268,P<0.05),and in comparison of 1:10 group with >1:10 group(χ2=4.411,P<0.05),their differences were statistically significant.Conclusions This study suggests that boys are more susceptible to ITP,espe-cially in the <3 age group.The total positive rate of HPA is higher in <3 years old group.The HPA has a certain guiding significance for the diagnosis of ITP.Compared with the other 2 groups,HPA>1:10 group may have higher short-term efficiency in clinical practice.

BACKGROUND:Conducting mental fatigue research in sports depends on appropriate mental fatigue induction tasks.However,the different types and time settings for the tasks in this field have interfered with the selection and determination of the appropriate task for mental fatigue research. OBJECTIVE:To compare the effects of three mental fatigue tasks and their commonly used time settings for mental fatigue induction. METHODS:In this randomized crossover study,16 male amateur soccer players performed four tasks of 60-minute duration with an interval≥48 hours in a randomized counter-balanced order:STROOP task(psychological cognition group),social media use in smartphone(electron exposure group),whole-body coordination task(exercise group)and emotionally neutral video watching as controls(control group).Before each task,the visual analogue scale(VAS)-motivation,VAS-mental fatigue,VAS-physical fatigue,and average heart rate were measured.Also,the VAS-mental fatigue,VAS-mental exertion,VAS-physical fatigue,and average heart rate were recorded every 15 minutes during the task.Repeated measures analysis of variance was mainly used for statistical analysis. RESULTS AND CONCLUSION:The baseline level of VAS-mental fatigue in the four groups were similar(P=0.806).(2)The VAS-mental fatigue of the psychological cognition group at 30,45 and 60 minutes was significantly higher than that of the other three groups(all P＜0.05).The VAS-mental fatigue of psychological cognition,electron exposure,and exercise groups at 45 minutes were similar with that at 60 minutes(all P＞0.05),but significantly higher than that of pretest,15 minutes and 30 minutes(all P＜0.05).To conclude,the psychological cognition task is superior to the electron exposure and exercise tasks for mental fatigue induction and 45 minutes is the appropriate length of time to effectively induce mental fatigue.
