ObjectiveTo analyze the data structure and standards of rehabilitation outpatient medical records, to provide data support for improving the quality of rehabilitation outpatient care and developing medical insurance payment policies. MethodsBased on the normative documents issued by the National Health Commission, Basic Standards for Medical Record Writing and Standards for Electronic Medical Record Sharing Documents, in accordance with the Quality Management Regulations for Outpatient (Emergency) Diagnosis and Treatment Information Pages (Trial), reference to the framework of the World Health Organization Family of International Classifications (WHO-FICs), the data framework and content of rehabilitation outpatient medical records were determined, and the data standards were discussed. ResultsThis study constructed a data framework for rehabilitation outpatient medical records, including four main components: patient basic information, visit process information, diagnosis and treatment information, and cost information. Three major reference classifications of WHO-FICs, International Classification of Diseases, International Classification of Functioning, Disability and Health, and International Classification of Health Interventions,were used to establish diagnostic standards and standardized terminology, as well as coding disease diagnosis, functional description, functional assessment, and rehabilitation interventions, to improve the quality of data reporting, and level of quality control in rehabilitation. ConclusionThe structuring and standardization of rehabilitation outpatient medical records are the foundation for sharing of rehabilitation data. The using of the three major classifications of WHO-FICs is valuable for the terminology and coding of disease diagnosis, functional description and assessment, and intervention in rehabilitation outpatient medical records, which is significant for sharing and interconnectivity of rehabilitation outpatient data, as well as for optimizing the quality and safety of rehabilitation medical services.

ObjectiveTo explore the standardization of inpatient rehabilitation medical record summary sheet, encompassing its structure, content and data standards, to enhance the standardization level of inpatient rehabilitation medical record summary sheet, improve data reporting quality, and provide accurate data support for medical insurance payment, hospital performance evaluation, and rehabilitation discipline evaluation. MethodsBased on the relevant specifications of the National Health Commission's Basic Norms for Medical Record Writing, Specifications for Sharing Documents of Electronic Medical Records, and Quality Management and Control Indicators for Inpatient Medical Record Summary Sheet (2016 Edition), this study analyzed the structure and content of the inpatient rehabilitation medical record summary sheet. The study systematically applied the three major reference classifications of the World Health Organization Family of International Classifications, International Classification of Diseases (ICD-10/ICD-11, ICD-9-CM-3), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), for disease diagnosis, functional description and assessment, and rehabilitation intervention, forming a standardized terminology system and coding methods. ResultsThe inpatient rehabilitation medical record summary sheet covered four major sections: inpatient information, hospitalization information, diagnosis and treatment information, and cost information. ICD-10/ICD-11 were the standards and coding tools for admission and discharge diagnoses in the inpatient rehabilitation medical record summary sheet. The three functional assessment tools recommended by ICD-11, the 36-item version of World Health Organization Disability Assessment Schedule 2.0, Brief Model Disability Survey and Generic Functioning domains, as well as ICF, were used for rehabilitation functioning assessment and the coding of outcomes. ICHI Beta-3 and ICD-9-CM-3 were used for coding surgical procedures and operations in the medical record summary sheet, and also for coding rehabilitation intervention items. ConclusionThe inpatient rehabilitation medical record summary sheet is a summary of the relevant content of the rehabilitation medical record and a tool for reporting inpatient rehabilitation data. It needs to be refined and optimized according to the characteristics of rehabilitation, with necessary data supplemented. The application of ICD-11/ICD-10, ICF and ICHI Beta-3/ICD-9-CM-3 classification standards would comprehensively promote the accuracy of inpatient diagnosis of diseases and functions. Based on ICD-11 and ICF, relevant functional assessment result data would be added, and ICHI Beta-3/ICD-9-CM-3 should be used to code rehabilitation interventions. Improving the quality of rehabilitation medical records and inpatient rehabilitation medical record summary sheet is an important part of rehabilitation quality control, and also lays an evidence-based data foundation for the analysis and application of inpatient rehabilitation medical record summary sheet.

Objective:To summarize the genetic and phenotypic features of MORC family CW-type zinc finger 2 (MORC2) gene-related neuropathy in Chinese patients. Methods:The clinical and whole exome sequencing data of MORC2 gene-related neuropathy families with a definitive genetic diagnosis were collected from the Third Xiangya Hospital of Central South University between 2010 and 2023. Literature involving Chinese families with MORC2 gene-related neuropathy was extensively reviewed to provide a comprehensive summary of the genetic and phenotypic spectrum of the disease. Results:A total of 10 families with MORC2 gene-related neuropathy were identified and analyzed. Six different heterozygous pathogenic variants in the MORC2 gene were observed among these families, including the novel variant c.1330G>C (p.G444R) that had not been previously reported. Six families presented as axonal Charcot-Marie-Tooth disease caused by variants in the MORC2 gene (CMT2Z) phenotype with childhood or adult onset, and carried variants c.754C>T (p.R252W), c.1199A>G (p.Q400R), c.1330G>C (p.G444R), or c.1396G>A (p. D466N); 3 families manifested as severe spinal muscular atrophy (SMA)-like phenotype with infantile onset, all carried c.260C>T (p.S87L); 1 family carried c.1181A>G (p.Y394C), presented as DIGFAN syndrome phenotype with infantile onset combined with mental and motor retardation. Systematic review showed 8 Chinese families carried pathogenic variants of the MORC2 gene, among which 5 families were associated with the CMT2Z phenotype, carrying c.754C>T (p.R252W), c.1079A>G (p.E360G), c.1220G>A (p.C407Y), or c.1397A>G (p.D466G); 1 family was associated with SMA-like phenotype, carrying c.260C>T (p.S87L); and 2 families were associated with DIGFAN syndrome, carrying c.79G>A (p.E27K) and c.292G>A (p.G98R). Conclusions:A novel pathogenic variant c.1330G>C (p.G444R) of the MORC2 gene associated with the CMT2 phenotype is reported. Eleven pathogenic variants of the MORC2 gene have been reported in the Chinese patients to date, and c.754C>T(p.R252W) may be the most common. Patients with MORC2 gene-related neuropathy carrying different variants present with significant clinical heterogeneity, manifesting as CMT2Z, early-onset severe SMA-like myasthenia, or DIGFAN syndrome.

Background Shoemaking industry workers are prone to work-related musculoskeletal disorders (WMSDs) due to long-term awkward postures during the work process. There is little research on the prevalence and influencing factors of WMSDs in the knee region of this industry, and it should be taken seriously. Objective To estimate the prevalence of work-related knee pain among shoemaking workers and analyze the related influencing factors. Methods A total of 6982 shoemaking workers were selected from 26 shoemaking factories in Guangdong, Hubei, Fujian, Chongqing, Shandong, Zhejiang, and Jingxi by convenience sampling. Prevalence of work-related knee pain in past year, demographic characteristics, occupational related factors, and work posture were collected by a cross-sectional survey using the electronic version of Musculoskeletal Disorder Questionnaire. Logistic regression analysis was used to analyze the influencing factors that may lead to work-related knee pain. Results This survey collected 6982 valid questionnaires with a recovery rate of 98.3%. The prevalence of work-related knee pain of shoemaking workers in the past 12 months was 13.0% (908/6982). According to the results of logistic regression analysis, compared with workers with less than 5 years of service, workers with 5-10 years of service (OR=1.21, 95%CI: 1.02, 1.45) and more than 10 years (1.53, 95%CI: 1.27, 1.83) showed a higher risk of knee WMSDs; sometimes, often and very frequent (reference : rarely or never) long-term standing (OR=1.33, 95%CI: 1.08, 1.64; OR=2.67, 95%CI: 2.10, 3.39; OR=2.75, 95%CI: 2.08, 3.63) and sometimes, often and very frequent (reference: rarely or never) long-term squatting or kneeling (OR=1.80, 95%CI: 1.47, 2.21; OR=2.43, 95%CI: 1.58, 3.75; OR=3.22, 95%CI: 1.66, 6.24) increased the risk of knee pain: long-term bending (OR=1.59, 95%CI: 1.34, 1.89) and often repeated movement of lower limbs and ankles (OR=1.48, 95%CI: 1.25, 1.75) were also risk factors for knee WMSDs among shoemaking industry workers (P<0.05). Adequate rest time (OR=0.58, 95%CI: 0.49, 0.68) and able to stretch or change leg posture (OR=0.75, 95%CI: 0.64, 0.88) reduced the risk of knee WMSDs (P<0.05). Conclusion In the shoemaking industry, length of service and awkward postures are risk factors for knee pain. The shoemaking enterprises should ensure that workers have sufficient rest time, reduce long-term standing, squatting, kneeling, and bending postures, as well as lower limbs repetition in order to reduce the occurrence of knee WMSDs of workers.

Objective:Cardiac arrest (CA) represents a significant public health challenge, posing a substantial threat to individual health and survival. To enhance the survival rates of patients experiencing out-of-hospital cardiac arrest (OHCA), Baoan District in Shenzhen City has undertaken exploratory initiatives and practical interventions, yielding promising preliminary outcomes.Methods:1.Innovate emergency medical services by developing a "four-circle integration" system that connects to the hospital. This system encompasses the social emergency medical system, the out-of-hospital emergency medical system, the in-hospital emergency medical service system, and the intensive care treatment system. 2.Develop a comprehensive model for the construction of a social emergency medical training system, characterized by party leadership, government oversight, departmental coordination, professional guidance, technological support, and community involvement, termed the "Baonan Model." Additionally, establish evaluation criteria to assess the effectiveness of the social emergency medical training system in Baonan District; 3. Develop a cardiac arrest registration system and a social emergency medical training management system for Baonan District; 4. Enhance the proficiency in treatment techniques and the quality of cardiopulmonary resuscitation among emergency medical professionals; 5. Strengthen and advance the development of a "five-minute social rescue network" to address the critical "emergency window period." .Result:In Baonan District, 9.18% of the public is trained in emergency medical skills. The bystander CPR rate for OHCA is 26.11%, AED use is at 4.78%, the 30-day survival rate is 6.31%, and the discharge survival rate is 4.44%.Conclusion:The implementation of the aforementioned measures can substantially enhance the survival rate of patients experiencing OHCA at the time of discharge.

Objective:Hereditary neuropathy with liability to pressure palsy(HNPP)is a rare autosomal dominant peripheral neuropathy,usually caused by heterozygous deletion mutations in the peripheral myelin protein 22(PMP22)gene.This study aims to investigate the clinical and molecular genetic characteristics of HNPP. Methods:HNPP patients in the Department of Neurology at Third Xiangya Hospital of Central South University from 2009 to 2023 were included in this study.The general clinical data,nervous electrophysiological and molecular genetic examination results were collected and analyzed.Molecular genetic examination was to screen for deletion of PMP22 gene using multiplex ligation-dependent probe amplification(MLPA)after extracting genomic DNA from peripheral blood;and if no PMP22 deletion mutation was detected,next-generation sequencing was used to screen for PMP22 point mutations.The related literatures of HNPP were reviewed,and the clinical and molecular genetic characteristics of HNPP patients were analyzed. Results:A total of 34 HNPP patients from 24 unrelated Chinese Han families were included in this study,including 25 males and 9 females.The average age at illness onset was 22.0 years.Sixty-two point five percent of the families had a positive family history.Among them,30 patients had symptoms of peripheral nerve paralysis.Patients often presented with paroxysmal single limb weakness with(or)numbness(25/30),and some patients had paroxysmal unilateral recurrent laryngeal nerve(vagus nerve)paralysis(2/30).Physical examination revealed muscle weakness(23/29),hypoesthesia(9/29),weakened or absent ankle reflexes(20/29),distal limb muscle atrophy(8/29)and high arched feet(5/29).Most patients(26/30)could fully recover to normal after an acute attack.Thirty-one patients in our group underwent nervous electrophysiological examination,and showed multiple demyelinating peripheral neuropathies with both motor and sensory nerves involved.Most patients showed significantly prolonged distal motor latency(DML),mild to moderate nerve conduction velocity slowing,decreased amplitude of compound muscle action potential(CMAP)and sensory nerve action potential(SNAP),and sometimes with conduction block.Nerve motor conduction velocity was(48.5±5.5)m/s,and the CMAP amplitude was(8.4±5.1)mV.Nerve sensory conduction velocity was(37.4±10.5)m/s,and the SNAP amplitude was(14.4±15.2)μV.There were 24 families,23 of whom had the classical PMP22 deletion,the last one had a heterozygous pathogenic variant in the PMP22 gene sequence(c.434delT).By reviewing clinical data and genetic testing results of reported 1 734 HNPP families,we found that heterozygous deletion mutation of PMP22 was the most common pathogenic mutation of HNPP(93.4%).Other patients were caused by PMP22 small mutations(4.0%),PMP22 heterozygous gross deletions(0.6%),and PMP22 complex rearrangements(0.1%).Thirty-eight sorts of HNPP-related PMP22 small mutations was reported,including missense mutations(10/38),nonsense mutations(4/38),base deletion mutations(13/38),base insertion mutations(3/38),and shear site mutations(8/38).HNPP patients most often presented with episodic painless single nerve palsy.Common peroneal nerve,ulnar nerve,and brachial plexus nerve were the most common involved nerves,accounting for about 75%.Only eighteen patients with cranial nerve involved was reported. Conclusion:Heterozygous deletion mutation of PMP22 is the most common pathogenic mutation of HNPP.Patients is characterized by episodic and painless peripheral nerve paralysis,mainly involving common peroneal nerve,ulnar nerve,and other peripheral nerves.Nervous electrophysiological examination has high sensitivity and specificity for the diagnosis of HNPP,which is manifested by extensive demyelinating changes.For patients with suspected HNPP,nervous electrophysiological examination and PMP22-MLPA detection are preferred.Sanger sequencing or next generation sequencing can be considered to detect other mutations of PMP22.

Arrhythmogenic cardiomyopathy (ACM), a fatal heart disease characterized by fibroadipocytic replacement of cardiac myocytes, accounts for 20% of sudden cardiac death and lacks effective treatment. It is often caused by mutations in desmosome proteins, with Desmoglein-2 (DSG2) mutations as a common etiology. However, the mechanism underlying the accumulation of fibrofatty in ACM remains unknown, which impedes the development of curative treatment. Here we investigated the fat accumulation and the underlying mechanism in a mouse model of ACM induced by cardiac-specific knockout of Dsg2 (CS-Dsg2 ^-/-). Heart failure and cardiac lipid accumulation were observed in CS-Dsg2 ^-/- mice. We demonstrated that these phenotypes were caused by decline of fatty acid (FA) β-oxidation resulted from impaired mammalian target of rapamycin (mTOR) signaling. Rapamycin worsened while overexpression of mTOR and 4EBP1 rescued the FA β-oxidation pathway in CS-Dsg2 ^-/- mice. Reactivation of PPARα by fenofibrate or AAV9-Pparα significantly alleviated the lipid accumulation and restored cardiac function. Our results suggest that impaired mTOR-4EBP1-PPARα-dependent FA β-oxidation contributes to myocardial lipid accumulation in ACM and PPARα may be a potential target for curative treatment of ACM.

Objective:To explore the impact of PM 2.5 concentration in Shanghai on the incidence of allergic rhinitis（AR） in the population, and provide strategies for early warning and prevention of AR. Methods:Collect daily average concentrations of atmospheric pollutants monitored in Shanghai from January 1, 2017 to December 31, 2019, and clinical data of AR patients from five hospitals in Shanghai during the same period. We used a time-series analysis additive Poisson regression model to analyze the correlation between PM 2.5 levels and outpatient attendance for AR patients. Results:During the study period, a total of 56 500 AR patients were included, and the daily average concentration of PM 2.5 was（35.28±23.07）μg/m³. There is a correlation between the concentration of PM 2.5 and the number of outpatient attendance for AR cases. There is a positive correlation between the daily average number of outpatient for AR and levels of PM 2.5 air pollution（（P<0.05）） . We found that every 10 μg/m³ increase in PM 2.5, the impact of on the number of AR visits was statistically significant on the same day, the first day behind, and the second day behind, with the strongest impact being the exposure on the same day. Every 10 μg/m³ increases in PM 2.5, the number of outpatient visits increased by 0.526% on the same day（95%CI 1.000 50-1.010 04）. Conclusion:The atmospheric PM 2.5 concentration in Shanghai is positively correlated with the number of outpatient for AR, and PM 2.5 exposure is an independent factor in the onset of AR. This provides an important theoretical basis for AR.

Objective To analyze the epidemiological investigation results and emergency response to a coronavirus disease 2019 （COVID-19） epidemic in Shanghai. Methods Descriptive epidemiological method was used to describe the epidemiological characteristics， such as population， time and spatial distribution of a COVID-19 epidemic on January 20， 2021 in Huangpu District of Shanghai. The advantages and disadvantages of the emergency response to this epidemic were analyzed. Results All of the 22 cases were found by active screening， which included high-risk population screening （18.2%， 4/22）， medium-risk area screening （9.1%， 2/22）， and close contact population screening （72.7%，16/22）. The first 2 cases were detected by routine nucleic acid screening for staff in two hospitals. The confirmed cases appeared mostly during the first 3 days of the epidemic （45.5%，10/22）， and mainly distributed in the neighborhood C of Huangpu district. There were 6 key locations or regions of Huangpu District involved in this epidemic， and different control measures were adopted in these different regions according to the risk assessments. After precise epidemic prevention and control， it took only 14 days from the first to the last confirmed case of this epidemic （from January 21， 2021 to February 4， 2021）， and no new related cases appeared afterwards. Conclusion Active screening and early finding of COVID-19 cases play a key role in timely control of the epidemic， with the smallest cost， the highest efficiency and the most limited urban impact.

Objective:To investigate the relationship between previous bleeding history and poor prognosis of patients with acute upper gastrointestinal bleeding.Methods:This study was a prospective multicentre real-world study (Acute Upper Gastrointestinal Real-word study, AUGUR study). The data of patients with UGIB who were admitted to the emergency department of 20 tertiary hospitals in China from June 30, 2020 to February 10, 2021 were collected. According to the number of previous bleeding history, the patients were divided into three groups (0 time, 1-3 times, and≥4 times). Based on the patient’s demographic data, clinical characteristics, laboratory data, treatment, and outcomes, univariate and logistic regression analysis were performed to investigate the correlation between the number of previous bleeding and the 90-day mortality and rebleeding of patients with gastrointestinal bleeding.Results:A total of 1 072 patients with acute UGIB were included in this study. The all-cause mortality and rebleeding rate of all patients were 10.9% (117/1 072) and 11.8% (129/1 072), respectively. Among them, 712 patients (66.42%) had no previous bleeding, 297 patients (27.71%) had previous bleeding 1-3 times, and 63 patients (5.88%) had previous bleeding≥4 times. In univariate analysis, age, vital signs and consciousness on admission, history of liver cirrhosis, onset with hematemesis, admission hemoglobin, varicose veins bleeding, peptic ulcer bleeding, red blood cell infusion, tracheal intubation and the use of vasopressors after admission were risk factors for the 90-day mortality and rebleeding rate. Multivariate logistic regression analysis showed that patients with previous bleeding≥4 times had a higher risk of the 90-day mortality ( OR=2.17, 95% CI: 1.04-4.57, P=0.040) and rebleeding ( OR=2.32, 95% CI: 1.19-4.53, P=0.013). Conclusions:The history of previous bleeding≥ 4 times can be used as an independent risk factor for the 90-day mortality and rebleeding in patients with acute UGIB.
