Abstract In recent years, the research perspective of the prevention and intervention of children s sexual assault abroad has expanded from the victim s perspective of children s self protection education and post mortem remedy to the screening and intervention education of perpetrators in advance, so as to implement the primary prevention of children s sexual assault from the source. The article will summarize the current situation of foreign research on child sexual assault prevention from the perspective of perpetrators, including the target population, prevention practice and forms, so as to provide a reference for the primary prevention of child sexual assault from the perspective of perpetrators in China.

Objective:To investigate the efficacy and safety of fecal microbiota transplantation (FMT) in the treatment of irritable bowel syndrome (IBS), and to explore the effects of FMT on the gut microbiota of IBS patients.Methods:From September 2016 to August 2017, at Guangzhou First People′s Hospital, 28 hospitalized IBS patients who underwent FMT treatment were enrolled. Before FMT, four and 12 weeks after FMT, all the IBS patients completed the irritable bowel syndrome quality of life scale (IBS-QOL), irritable bowel syndrome severity scoring system (IBS-SSS) and gastrointestinal symptom rating scale (GSRS). 16S rDNA sequencing was performed before FMT and four weeks after FMT. The effects of FMT on gut microbiota diversity and microbiota structure of IBS patients were analyzed respectively from the level of phylum, family and genus, and linear discriminant analysis effect size (LEfSe) was further used to screen the different bacteria. Paired t test and paired rank sum test were used for statistical analysis. Results:Twelve weeks after FMT, the scores of the six dimensions of IBS-QOL including dysthymia, behavioral disorder, auto imagery, health concerns, eating avoidance, and relationship expansion were all lower than those before FMT (43.750, 22.656 to 56.250 vs. 48.438, 32.031 to 60.938; 37.500, 18.750 to 56.250 vs. 46.429, 21.429 to 62.500; 31.250, 14.063 to 42.188 vs. 31.250, 18.750 to 50.000; 41.667, 27.083 to 56.250 vs. 50.000, 41.667 to 66.667; 54.167, 43.750 to 72.917 vs. 66.667, 58.333 to 83.333; 8.333, 0.000 to 33.333 vs. 16.667, 8.333 to 33.333, respectively), and the differences were statistically significant ( Z=-2.157, -3.429, -2.274, -3.197, -3.042 and -2.329, all P<0.05). Twelve weeks after FMT, the scores of the two dimensions of IBS-QOL including behavioral disorder and relationship expansion were both lower than those of four weeks after FMT (37.500, 18.750 to 56.250 vs. 39.286, 19.643 to 62.500 and 8.333, 0.000 to 33.333 vs. 16.670, 2.083 to 41.667, respectively), and the differences were statistically significant ( Z=-1.998 and -2.110, both P<0.05). Four and 12 weeks after FMT, the scores of IBS-SSS and GSRS were both lower than those before FMT ((190.32±106.51), (201.43±102.48) vs. (245.93±86.10) and 5.50, 4.00 to 9.00 and 5.50, 4.00 to 8.75 vs. 7.00, 6.00 to 9.75), and the differences were statistically significant ( t=4.402 and 3.848, Z=-3.081 and -3.609; all P<0.01). No serious adverse reactions occurred in the patients after FMT. At the phylum level, after FMT the abundance of Verrucomicrobia in the feces of IBS patients was richer than that before FMT (6.74% vs. 0.37%); at the family level, after FMT the abundance of Verrucomicrobiaceae in the feces of IBS patients was richer than that before FMT (6.74% vs. 0.37%); at the genus level, after FMT the abundance of Akkermansia was richer than that before FMT (6.74% vs. 0.37%); and the differences were statistically significant (all Z=-2.589, all P=0.010). The results of LEfSe method indicated that four weeks after FMT the abundance of Akkermansia in the gut microbiota of IBS patients was richer than that before FMT (6.74% vs. 0.37%), and the difference was statistically significant (linear discriminant analysis value=4.5, P=0.049). Conclusions:FMT is safe and effective in the treatment of IBS. The mechanism may be through upregulating the diversity of gut microbiota and changing the structure of gut microbiota of IBS patients.

Objective:To explore the application effect of quantitative exercise nursing intervention based on WeChat platform in the recovery of patients with lower extremity arteriosclerosis obliterans.Methods:A total of 128 patients with lower extremity arteriosclerosis obliterans who were treated in Department of Vascular Surgery of the First Affiliated Hospital of Zhengzhou University were selected from June 2019 to February 2021. They were randomly divided into the control group and the observation group, with 64 cases in each group. The control group used routine nursing, while the observation group used the quantitative exercise nursing intervention based on the WeChat platform. Ankle-brachial index (ABI) and walking ability [Walking Impairment Questionnaire (WIQ) ] were compared between the two groups. The quality of life and nursing satisfaction of patients in two groups were investigated by World Health Organization Quality of Life Assessment Brief Scale (WHOQOL-BREF) and Newcastle Satisfaction with Nursing Scale (NSNS) .Results:After the intervention, scores of ABI, WIQ, WHOQOL-BREF and nursing satisfaction of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Quantitative exercise nursing intervention based on the WeChat platform can promote the functional rehabilitation of patients with lower extremity arteriosclerosis obliterans and improve quality of life and satisfaction of patients, which is worthy of clinical application.

Objective:To investigate the infection incidence of women with high-risk human papillomavirus(HPV) A9 in Quzhou, and to analyze its clinical significance in cervical cancer screening by combining with liquid-based cytology(TCT).Methods:A total of 9 010 patients were collected from January 2017 to May 2018 in the Maternal and Child Health Hospital of Quzhou.HPV detection was performed by Cervista method.In combination with TCT, cervical biopsy was carried out under vaginal microscopy.Results:Among 9 010 patients, 1 401 patients were HPV positive, and the A9 group had the highest rate for inspection(6.98%). The experiment data of the A9 group indicated that the portions of cervical intraepithelial lesions in liquid-based cytology NILM, ASC-US, LSIL, ASC-H, HSIL, SCC were 5.96%, 80.10%, 100.00%, 100.00%, 100.00%, respectively.Its coincidence rate with histology increased as liquid-based cytology increased, associated with high-grade lesions.Conclusion:A9 group infection is the most important cause of cervical intraepithelial lesions in Quzhou.High-risk HPV test, especially A9 group infection combined with TCT, can effectively improve the accuracy of cervical cancer screening.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause acute respiratory distress syndrome, hypercoagulability, hypertension, and multiorgan dysfunction. Effective antivirals with safe clinical profile are urgently needed to improve the overall prognosis. In an analysis of a randomly collected cohort of 124 patients with COVID-19, we found that hypercoagulability as indicated by elevated concentrations of D-dimers was associated with disease severity. By virtual screening of a U.S. FDA approved drug library, we identified an anticoagulation agent dipyridamole (DIP) , which suppressed SARS-CoV-2 replication . In a proof-of-concept trial involving 31 patients with COVID-19, DIP supplementation was associated with significantly decreased concentrations of D-dimers ( < 0.05), increased lymphocyte and platelet recovery in the circulation, and markedly improved clinical outcomes in comparison to the control patients. In particular, all 8 of the DIP-treated severely ill patients showed remarkable improvement: 7 patients (87.5%) achieved clinical cure and were discharged from the hospitals while the remaining 1 patient (12.5%) was in clinical remission.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.
