AIM:To investigate myopia status and analyze the influence factors in children and adolescent in Wulong district of Chongqing.METHODS:Cross-sectional study. A stratified cluster sampling method was used to select 2 504 primary and secondary school students in Wulong district, and all students underwent myopia screen and questionnaire survey, statistics and analyses the data.RESULTS:Totally 2 431 students were participated in this study, and 1 217 students with myopia were screened out, the prevalence rate of myopia was 50.06%, awareness rate of myopia was 64.59%, glasses wearing rate of myopia was 51.85%. The prevalence of myopia increased with age and grade(P<0.05), the prevalence of myopia in male(46.97%)was lower than in female(53.18%), and the prevalence of myopia in township(47.06%)was lower than in urban area(52.11%; all P<0.05). Regression analysis showed that outdoor activities were protective factor for myopia, while female, myopic parents, near vision work, short sleep duration and sweet tooth were risk factors for myopia.CONCLUSION:The prevalence rate of myopia was higher in children and adolescent in Wulong district of Chongqing, awareness rate of myopia and glasses wearing rate of myopia were lower, and the genesis of myopia is highly relevant to outdoor activities, gender, myopic parents, near vision work, short sleep duration and sweet tooth.

AIM: To compare the efficacy of different dosing regimens of conbercept in the treatment of pathological myopic choroidal neovascularization(CNV).METHODS: Prospective clinical study. Totally 42 patients(42 eyes)who were diagnosed with pathological myopic CNV in our hospital from January 2019 to January 2022 were selected in the study. According to two different initial dosing regimens, the patients were divided into 1+pro re nata(PRN)group, with 20 patients(20 eyes), and 3+PRN group with 22 patients(22 eyes). The patients in the 1+PRN group were given one intravitreal injection and then given PRN, the patients in the 3+PRN group were given intravitreal injection once a month for 3 mo and then given PRN. Followed-up for 12 mo after initial treatment, the best corrected visual acuity(BCVA), central macular thickness(CMT), CNV area and injection times were compared between the two groups.RESULTS: The BCVA was improved, CMT was decreased, and CNV area was reduced at 1, 3, 6, and 12 mo after the initial treatment(P<0.01). However, there was no statistically significant difference in BCVA, CMT and CNV area between two groups(P>0.05). The average injection in the 1+PRN group was significantly less than that of the 3+PRN group [2(1, 3)times vs 3(3, 4)times, P<0.05], but the average reinjection in the 1+PRN group was more than that of the 3+PRN group [1(0, 2)times vs 0(0, 1)times, P<0.05].CONCLUSION: Two regimens were both safe and effective in the treatment of pathological myopic CNV by Conbercept, which can improve BCVA, decrease CMT, and reduce CNV area, with less total times of injection in the 1+PRN regimen, and less times of reinjection in the 3+PRN regimen.

ObjectiveTo understand the characteristics of high-risk inmates’ impulsivity and to explore the influencing factors of impulsivity， so as to provide a theoretical basis for identifying the high-risk factors and making effective intervention. MethodsA total of 588 male inmates in Nanjing were selected as the research subjects. They were divided into four groups according to their violent crime reasons， high impulsiveness， borderline personality and antisocial personality. The detailed criminal records of inmates， general demographic data questionnaire， self-made substance use questionnaire， Barratt Impulsiveness Scale （BIS-11） and Childhood Trauma Questionaire-Short Form （CTQ-SF） were used to investigate， and multiple stepwise regression analysis was conducted to analysis the influencing factors of impulsivity of high-risk inmates. Results① There were statistically significant differences in age， marital status and drug use history among the four groups （F=4.890、13.945、26.137， P<0.01）. ② There were statistically significant differences in BIS-11 and CTQ-SF scores among the four groups （F=81.196， 16.208， P<0.01）. ③ Drug use history （β=1.832， P<0.05）， affective neglect （β=0.278， P<0.01） and affective abuse （β=0.307， P<0.01） had positive predictive effects on impulsivity of all high-risk inmates. Affective neglect （β=0.482， P<0.01） had a positive predictive effect on impulsivity of violent criminals. ConclusionDrug use history， affective neglect and emotional abuse were the risk factors for high impulsivity in male high-risk inmates.

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.

PURPOSE: Recent evidence suggests that B cells can both promote and inhibit the development and progression of allergic disease. However, the characteristics of B cell subsets in patients with allergic rhinitis (AR) have not been well documented. This study aimed to analyze the characteristics of B cell subsets in the peripheral blood of AR patients. METHODS: Forty-seven AR patients and 54 healthy controls were enrolled in this study, and the B cell subsets in peripheral blood of all subjects were analyzed by flow cytometry. Moreover, the serum total immunoglobulin E (IgE) and IgE concentrations secreted into the cultured peripheral blood mononuclear cells (PBMCs) were measured by using enzyme-linked immunosorbent assay. RESULTS: We found the peripheral blood of AR patients contained higher percentages of memory B cells, plasma cells, and CD19+CD24hiCD27+ regulatory B cells (Bregs) than those of age-matched healthy controls (P < 0.05), while the percentages of naïve B cells and CD19+CD24hiCD38hi Bregs were significantly lower in AR patients than in healthy individuals (P < 0.05). In addition, the serum total IgE and IgE concentrations secreted into the cultured PBMCs were elevated in AR patients than in the healthy controls (P < 0.05). CONCLUSIONS: Our findings indicate that AR patients were characterized by increase in terminally differentiated memory B cells or plasma cells and decreases in CD19+CD24hiCD38hi Breg cells in the peripheral blood.

Objective To investigate the impulsive traits and their influencing factors in different types of male inmates. Methods A total of 1 206 male inmates in Jiangsu province were assessed by a self-designed questionnaire of detailed criminal records,demographic data,history of substance use and Barratt Impulsiveness Scale (BIS-11).Results ①Significant differences were found between the distribution of age (F＝30.092),educational level(χ2＝84.479),marital status(χ2＝54.386),household registration(χ2＝34.959),smoking history (χ2＝19.047)and drug use history( χ2＝563.144) of male inmates( all P＜0.01).②Difference of impulsivity was found between different types of male inmates,and scores of the impulsivity of the property inmates (total impulsivity (55.92±8.39),attentional impulsiveness (12.70±2.35),motor im-pulsiveness (18.50± 3.88),non-planning impulsivity ( 24.72 ± 4.91)) were significantly lower than other crime types (P＜0.05).③Drug use history had a positive predictive effect on impulsivity of male violent in-mates (B＝4.317,P＜0.01),and educational level(B＝－3.280,P＜0.001),age(B＝－0.094,P＜0.05)and drug use history ( B＝ 3.491, P＜ 0.05 ) had a predictive effect on impulsivity of male property inmates. Conclusion The impulsivity of male property inmates is significantly lower than others and the influence factors of impulsivity among male inmates are age,educational level and drug use history.

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.

This study aimed to evaluate the feasibility and effectiveness of closing the small bowel in an ex vivo porcine model with high-frequency welding device. A total of 100 porcine small bowels were divided into two groups, and then were closed with two different methods. The fifty small bowels in experimental group were closed by the high-frequency welding device, and the other fifty small bowels in comparison group were hand-sutured. All the small bowels were subjected to leak pressure testing later on. The speed of closure and bursting pressure were compared. The 50 porcine small bowels closed by the high-frequency welding device showed a success rate of 100%. Compared with the hand-sutured group, the bursting pressures of the former were significantly lower (P<0.01) and the closing process was significantly shorter (P<0.01). The pathological changes of the closed ends mainly presented as acute thermal and pressure induced injury. Experimental results show that the high-frequency welding device has higher feasibility in closing the small bowel.
