Abstract Child abuse is a global public health problem, which has emerged as a neglected yet pressing issue in global development. Early and accurate identification of abuse at a lower-age group is of great significance for treatment, which might reduce the risk of re-maltreatment and promote children s physical and mental health development. Therefore, by reviewing the clinical characteristics, risk factors and existing abuse identification and screening tools of child abuse, the study aims at providing basic evidence for the development of child abuse risk identification tools and the establishment of child maltreatment system in China, so as to take timely intervention measures to prevent adverse outcomes or reduce their severity.

Objective:To summarize and discuss the surgical effect in otoplasty of prominent ear using cartilage folding with unilateral cartilage incision.Methods:Data of patients with prominent ear who were treated in the Department of Vascular and Plastic Surgery of Guangdong Provincial People’s Hospital and the Department of Plastic Surgery of Sun Yat-sen Memorial Hospital from May 2018 to April 2022 were retrospectively analyzed. All patients underwent otoplasty using cartilage folding with unilateral cartilage incision. During the operation, a unilateral cartilage incision was made along the lateral bottom of intended antihelix, cartilage dissection and scoring were made, and the cartilage was folded and sutured to form the antihelix. The patients were followed up postoperatively for auricular shape, wound healing and other complications.Results:A total of 18 patients with prominent ear (22 ears) were included, consisting of 12 males (15 ears) and 6 females (7 ears), aged from 18 to 51 years(average of 25.8 years). There were 9 cases on the left, 5 cases on the right and 4 cases on both sides. Four patients had pain in the operation area within 2 days postoperatively which could be relieved by analgesics. The patients were followed up for 1-24 months, with an average follow-up of 13.6 months. Twenty-two prominent ears were corrected. Scaphoconchal angle and cranioauricular angle of the prominent ears were significantly reduced, and the shape of the antihelix was smooth after the operation. All patients were satisfied with the results. There were no other complications after the operation, such as deformity relapse, infection, unhealing, auricular cartilage deformation and hypertrophic scar.Conclusions:Otoplasty of prominent ear using cartilage folding with unilateral cartilage incision is a simple, stable and satisfactory surgical method for the treatment of prominent ear.

Echinococcosis is a serious zoonosis parasitic disease caused by the parasitic larva of Echinococcus. Surgical treatment, as the preferred treatment of echinococcosis, has disadvantages such as small scope of application, difficulty in complete resection, high postoperative recurrence rate and heavy burden on patients. Drug therapy is not only a necessary supplement to the preoperative, intraoperative and postoperative treatment of echinococcosis patients, but also the first choice when surgical treatment is not applicable. This article reviews the physicochemical and pharmacokinetic properties of benzimidazole drugs, and summarizes the anti- Echinococcus activities of different benzimidazole formulations, it will provide a reference for future exploration of echinococcosis treatment drugs.

Objective:To address a new classification method in term of the three-dimensional space of orbit and to present the different surgical approaches correspondingly.Methods:In a retrospect study from April of 2015 to June of 2018, 102 patients were performed lower eyelid blepharoplasty, including 20 males and 82 females, aged 21-65 years, with an average of 45.2 years. These patients were divided into five groups, which were described in term of three-dimensional structure of orbit, based on the following points: the presence and extent of herniated orbital fat, the presence of inferior orbitopalpebral sulcus, amount of excess skin, and the skin wrinkles in the lower eyelid. And then patients in different group were treated with different kinds of blepharoplasty. All patients in this study ranged in follow-up from 1 month to 12 months. With patients＇ permit, photographs and clinical information were taken to evaluate the preoperative and postoperative outcome.Results:In type 1, all the 32 cases healed well, no complications such as hematoma, infection and ectropion occurred. During the follow-up of more than 1 months, the overall effect was good, and the pouch-shaped appearance of lower eyelid pouch was significantly improved. In types 2, 8 cases had no complications, and the incision healed well; the patients were followed up for more than 3 months, the lower eyelid bag and lower eyelid skin relaxation were significantly improved, and the lower eyelid skin was tighter than before. In types 3, there were no complications in these 19 cases, and the incision was healed well. The patients were followed up for more than 3 months, the deformity of lower eyelid bag was improved obviously, and no obvious local bulge was found under static and dynamic expression. In type 4, there were no complications in all 34 cases, and the incision healed well; during the follow-up of more than 3 months, the lower eyelid pouch deformity and lower eyelid skin relaxation were greatly improved, except for 1 case with mild bulge (untreated). In type 5, 9 cases had no complications, and the incision healed well; during the follow-up of more than 3 months, the fold of the lower eyelid skin disappeared.Conclusions:Little information is available about classification of lower eyelid bags. And the exact surgical approach remains controversial and largely dependent upon surgeon preference and a patient＇s stated cosmetic desire. In this study, an objective classification based on clinical appearance combined with forming reasons of lower eye bags is little available, and the appropriate surgical approach remains controversial as well.

Objective:To understand the status quo of self-stigma of diabetic patients in college students and analyze its influencing factors.Methods:This study was a cross-sectional study, and the convenient sampling was conducted online and offline from July 2017 to June 2020. College students with diabetes who were treated in outpatient or inpatient Departments of Endocrinology and Metabolism in 5 Class Ⅲ Grade A hospitals were selected as the research objects, and similar patients who followed 2 diabetes public accounts were selected as online supplements. General information questionnaire and China-Self Stigma Scale (C-SSS) were used for questionnaire surveys. Data were statistically processed by t-test, analysis of variance and multiple linear regression analysis. A total of 200 questionnaires were distributed, and 189 valid questionnaires were recovered, with an effective recovery rate of 94.50%. The self-stigma of 80.42% of college students with diabetes mellitus was at a medium-to-high level. The total average score of C-SSS was (2.34±0.49) , of which the mean scores of cognitive dimension, emotional dimension and behavioral dimension were respectively (2.33±0.50) , (2.41±0.57) and (2.19±0.64) . The results of univariate analysis showed that there were statistically significant differences in the stigma scores of diabetic patients with different genders, family locations, parental physical conditions, diabetes types, family history, diabetes complications and insulin treatment or not ( P<0.05) . The results of multiple linear regression analysis showed that gender and type of diabetes were factors affecting the self-stigma level of college students with diabetes mellitus ( P<0.05) . Conclusions:The level of self-stigma in college students with diabetes mellitus is generally high. Hospitals, schools and families should strengthen cooperation and pay attention to these with high level of self-stigma. Meanwhile, early prevention and control should be targeted through dynamic tracking, psychological counseling and other interventions.

Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors. Results: The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05). Conclusion The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

Objective: To understand the consciousness of the cancer early detection among urban residents and identify the influencing factors from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years. Results: The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05). Conclusion From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.

Objective: To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis. Results: As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05). Conclusions From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.

Objective: To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment. Results: With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05). Conclusion Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.
