Objective:This study aims to obtain the prevalence and features associated with Violence Against Children (VAC) in China and, thus, formulate a prevention strategy.Methods:The mortality-related data of VAC was sourced from the National Disease Surveillance Points System (DSP) during 2013-2021. We analyzed the DSP data regarding children aged 0-17 years old who died from violence. The hospital cases of VAC was sourced from the National Injury Surveillance System (NISS), 2013-2021. We analyzed the data from NISS with the parameter of "intentional injury" caused by VAC in children aged between 0-17 years. Using robust linear regression, we analyze the time trend in the proportion of violence incidence. To understand the variations in the incidence of different types of violence across genders, we apply the chi-square test and adjusted Pearson residuals.Results:The overall trend of death caused by VAC has declined; it was reduced to 0.14/100 000 in 2021 from 0.33/100 000 in 2013. In 2021, male VAC mortality (0.15/100 000) was higher than females (0.13/100 000). The proportion of VAC cases to all injury cases has declined from 3.34% in 2013 to 2.29% in 2021. Among 9 344 VAC cases supervised by hospitals in 2021, the number of males (7 503 cases) was around 4 times that of females (1 841 cases), and the top three modes of violence were blunt tools (64.77%), falls (7.46%) and sharp instruments (6.18%), and 45 cases of sexual violence included 38 girls and 7 boys.Conclusions:The declining death rate due to VAC may be related to the benign development of Chinese society. Prevention strategies targeting training in parenting skills and problem-solving should be prioritized.

The common data model (CDM) is an important tool to facilitate the standardized integration of multi-source heterogeneous healthcare big data, enhance the consistency of data semantic understanding, and promote multi-party collaborative analysis. The data collections standardized by CDM can provide powerful support for observational studies, such as large-scale population cohort study. This paper provides an in-depth comparative analysis of the data storage structure, term mapping pattern, and auxiliary tools development of the three international typical CDMs, then analyzes the advantages and limitations of each CDM and summarizes the challenges and opportunities faced in the CDM application in China. It is expected that exploring the advanced technical concepts and practical patterns of foreign countries in data management and sharing will provide references for promoting FAIR (findable, accessible, interoperable, reusable) construction of healthcare big data in China and solving the current practical problems, such as the poor quality of data resources, the low degree of semantization, and the inabilities of data sharing and reuse.

Objective To evaluate the molluscicidal activity of a novel molluscicide pyriclobenzuron against Oncomelania hupensis robertsoni in the mountain regions of Yunan Province, and test its toxicity to fish, so as to provide scientific evidence for the extensive application of this molluscicide in schistosomiasis-endemic foci of Yunan Province. Methods In the laboratory and snail-breeding field of Dali Prefecture, Yunnan Province, the molluscicidal activity of 5% wettable powder of pyriclobenzuron sulphate (25% PBU) against O. hupensis robertsoni was assessed by using the immersion and spraying method, and the acute toxicity of 25% PBU to carp fries was tested, while 25% wettable powder of niclosamide ethanolamine salt (50% WPNES) served as a control. Results The 1-, 2- and 3-day 25% PBU LC50 and LC90 values were 0.47, 0.25 and 0.23 mg/L, and 1.54, 0.61 and 0.49 mg / L for O. h. robertsoni by using the immersion method in laboratory, and immersion with 25% PBU at 1.0 mg / L for 1 day achieved a comparable molluscicidal efficacy in relative to 50% WPNES at 1.0 mg/L. Spraying with 25% PBU at 4.0 g/m² achieved 1-, 3- and 7-day snail mortalities of 64.23%, 96.67% and 100.00% in laboratory, respectively, which were not significantly different from those caused by treatment with 50% WPNES at 1.0 g/m² (all P values > 0.05). One-day field immersion with 25% PBU at doses of 1, 2 and 4 g/m³ resulted in snail mortalities of 90.00%, 93.33% and 100.00%, respectively, which were not significantly different from those caused by treatment with 50% WPNES at 1.0 g/m³ (all P values > 0.05), and 3-day field spraying with 25% PBU at doses of 2.0 and 4.0 g/m² caused snail mortalities of 86.36% and 87.72%, respectively, which were not significantly different from those caused by 50% WPNES treatment (both P values > 0.05). The 24-, 48- and 72-hour LC50 values of 25% PBU to carp fries were 29.38, 24.62 and 23.38 mg/L, respectively, and no fish death was observed within 72 hours of exposure to 25% PBU at a concentration of 17.5 mg/L and lower. Conclusion 25% PBU is a novel, highly potent and environment-friendly molluscicide that is feasible in fish ponds, and the recommended dose is 1 g/m³ for field immersion and 2 g/m² for field spraying in schistosomiasis-endemic areas of Yunnan Province.

As a new type of anti-cancer drugs, immune checkpoint inhibitors (ICIs) have shown remarkable therapeutic effects in many malignant tumors. By virtue of their targets and mechanisms of action, ICIs can cause autoimmune and inflammatory effects, termed immune-related adverse events (irAEs). Unlike traditional therapies, irAEs are latent and unstable. Severe adverse reactions will force patients to discontinue treatment and even affect their survival. Therefore, with the wide application of ICIs in clinical practice, clinicians need to fully understand the possible adverse reactions of such drugs and appropriate treatment strategies, in order to improve the survival rate and treatment effect of patients receiving ICIs. In this article, we review the incidence, clinical features, diagnosis and treatment of immune-related endocrine events that may occur with administration of ICIs.

Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.

Objective To evaluate the molluscicidal effect of niclosamidate against Oncomelania hupensis in laboratory and explore its mechanism by determining the enzyme activities of six important enzymes in snail soft tissues.Methods O.hupensis snails were treated with niclosamidate at the concentration of 1.25 mg/L for 24 h and the snail soft tissues were separated and pre-pared for analysis.The enzyme activities of NOS,AChE,SDH,LDH,ACP and AKP were determined by ultraviolet spectropho-tometry.The morphology of the snail soft tissue was also observed.Results Niclosamidate exhibited a potent molluscicidal ef-fect against O.hupensis at the concentration of 5.00 mg/L with a mortality of 96.67% by the immersion method in laboratory.Af-ter immersed with niclosamidate(1.25 mg/L)for 24 h,the enzyme activities of NOS,AChE,ACP and AKP were significantly decreased compared with those of the controls(all P<0.01).There were no significant changes observed in the enzyme activi-ties of SDH and LDH(both P>0.05).Conclusion Niclosamidate possesses a potent molluscicidal effect against O.hupensis and its molluscicidal mechanism is probably by affecting the transmission of neurotransmitters,interfering with the circulation, metabolism and motor functions that require NO,and hindering the digestion and absorption of nutriments,which eventually re-sult in the death of the snails.

Objective To develop a knowlodge-attitude-practice questionnaire (KAPQ) for abdominal surgery patients,in order to provide an available tool to evaluate the KAP status of patients' postoperative pain.Methods The KAPQ was established on the basis of clinical experience,literature review and expert consultation.Ninety patients with abdominal surgery in a three level hospital in Jiangsu province were chosen by convenient sampling and SPSS was used for the scale reliability and validity.Results The internal consistency reliabilities of the KAPQ and its three subscales were respectively 0.899,0.933,0.903 and 0.888.The copy of reliability of three subscales were respectively 0.886,0.763 and 0.821.The content coefficients of three subscales were respectively 0.946,0.921 and 0.949.Factor analysis showed that the questionnaire had good construct validity with a common explaining variance more than 0.4.Conclusions The KAPQ has good reliability and validity,thus it can be used as an effective tool to evaluate the health-related knowledge-attitudepractice of the abdominal surgery patients' postoperative pain.

OBJECTIVETo evaluate the efficacy of porcine anti-human lymphocyte globulin (P-ALG) plus cyclosporine A (CsA) therapy for severe aplastic anemia (SAA).

METHODSForty-eight SAA patients (31 males, 17 females) including 17 very severe aplastic anemias (vSAA) were treated with ALG plus CsA between 1999 to 2009 in our hospital and the outcomes were analyzed retrospectively for early mortality, response rate and quality, survival rate, toxicity and complications.

RESULTSThe median age was 28 (13 - 64) years. The interval from diagnosis to treatment was 45 days. The median neutrophil count at diagnosis was 0.178 × 10(9)/L. Overall response was 83.3% (54.2% complete, 29.2% partial) with a median time of 90 (23 - 380) days. 10.4% died of infection within 30 days mainly of fungi infection. Only 1 patient relapsed 2 years after treatment. No clonal disease was found. The 1.5-year survival rate was 87.5%. vSAAs had less response, higher early mortality and less survival (64.7%, 29.4% and 51.8%, respectively) compared to that of SAA (93.5%, 0, 100%, respectively, P < 0.05). Grouped patients with different age, gender, intervals between diagnosis and treatment and pre-existing infections had similar response. The main side effects were fever and skin rash (52.1%), serum sickness (16.7%), impaired liver function (60.4%) and hemorrhage (2.1%). No treatment-related mortality was found.

CONCLUSIONP-ALG plus CsA is an ideal and well tolerated treatment for SAA but not for vSAA.

Objective To investigate effects of 2 types of remote island environment on the vigilance and attention of garrison soldiers. Methods Attention distribution measuring instrument (EP-707A) and attention focus measuring instrument (EP-711) were used to measure total time of sound-light reaction, correct times of sound - light reaction, the time on targets as well as the time out of track of targets of garrison soldiers and the control group on the mainland. Results Effects of remote island environment on attention distribution of garrison soldiers were not significant in a considerably long time (within 5 years), while longer service (more than 5 years) on remote islands had certain effects on attention distribution of garrison soldiers. Remote island environment was not the most important factor affecting attention distribution of garrison soldiers. Conclusions Remote island environment only had certain effects on attention distribution of garrison soldiers with over 5 years of service.
