Background Depressive moods among occupational population are prevalent, which seriously affect their mental-physical health and socioeconomic productivity. This has become an urgent public health concern. Objective To understand current situation of depressive mood among an occupational population aged 18 to 60 covering 120 cities of China, and to explore the relationship between work-family conflict and depressive mood as well as the role of life stress in the relationship, as to provide a scientific basis for developing measures to reduce depressive mood in the occupational population. Methods Using the data of the Psychology and Behavior Investigation of Chinese Residents in 2021, an occupational population aged 18 to 60 years was selected as study subjects. A total of 3785 subjects were included in the study. The Work-Family Conflict Scale, Subjective Life Stress Scale, and Patient Health Questionnaire-Depression Scale were used to assess the work-family conflict, life stress, and depressive mood of the subjects. Harman's single-factor method was used to evaluate common method bias in the survey data. One-way ANOVA was applied to test the difference in work-family conflict, life stress, and depressive mood among occupational population by demographic characteristics, and chi-square test was used to analyze the difference in reporting depressive mood. Partial correlation analysis was used to evaluate the correlation between selected variables. Process plug-in was used to test potential mediating effect of life stress on work-family conflict and depressive emotion. Results The scores of work-family conflict, life stress, and depressive mood among the occupational population were 24.60±8.28, 9.28±3.78, and 5.43±5.30, respectively. The prevalence rates of depressive mood was 48.7% (1888/3875). The score of depressive mood among occupational population who never smoked was significantly higher than that of those who smoked (P<0.01). The partial correlation analysis showed that work-family conflict and life stress were positively correlated with depressive mood (r=0.472 and 0.447, P<0.001); work-family conflict was positively correlated with life stress (r=0.361, P<0.001). The mediation analysis results showed that work-family conflict positively associated with life stress (b=0.361, P<0.001); life stress positively associated with depressive mood (b=0.318, P<0.001); work-family conflict positively associated with depressive mood (b=0.357, P<0.001), and played a partial mediating role in the relationship between work-family conflict and depressive mood with an effect size of 0.115 (95%CI: 0.099, 0.130) that accounted for 24.36% of the total effect. Conclusion Work-family conflict may not only directly affect depressive mood among occupational population, but also indirectly affect depressive mood through a mediating effect of life stress.

Objective To analyze the status of persistent human papillomavirus (HPV) infection and the distribution of viral subtypes in the Zhengzhou region. Methods Clinical data of 55239 patients who underwent HPV-DNA genotyping tests from 2018 to 2024 were collected. On the basis of HPV follow-up results, patients were divided into three groups: 849 cases of infection with the same HPV type, 255 cases of persistent infection with different HPV types, and 857 cases of transient HPV infection. Results Among the 9232 initially-screened patients who were positive with HPV, the high-risk HPV (HR-HPV) positive rate was 84.6% (7813/9232), and predominant subtypes were HPV-16 (20.8%), HPV-52 (17.2%), and HPV-53 (9.6%). The low-risk HPV (LR-HPV) positive rate was 15.4% (1419/9232), mainly HPV-81 (28.1%) and HPV-42 (27.0%). Among the 1961 follow-up cases, the rates of persistent and non-persistent infections with the same HPV type were 35.7% (701/1961) and 7.5% (148/1961), respectively. The rates of persistent and non-persistent infections with different HPV types were 10.9% (214/1961) and 2.1% (41/1961), respectively. Meanwhile, 43.7% (857/1961) tested negative upon follow-up. Among the 701 cases of persistent infection with the same HPV type, HR-HPV accounted for 85.7% (601/701), and LR-HPV accounted for 14.3% (100/701). Among the 214 cases of persistent infection with different HPV types, 89.7% (192/214) were high-risk transitions, and 10.3% (22/214) were low-risk transitions. Regardless of HPV types, HR-HPV was more likely to cause persistent infection than LR-HPV. In addition, over 60% of HR-HPV persistent infections resolved within 18 months, 30% developed into persistent infections, and only 15% of patients had persistent infections that last more than 24 months. Conclusion Persistent HPV infections are predominantly high-risk types. Most patients clear the infection within 18 months, approximately 30% develop persistent infections, and about 15% of patients have persistent infections that last more than 24 months. However, the HR-HPV persistent infection rates across different age groups slightly differ.

Background Job burnout has become an important factor affecting the mental and physical health and work efficiency of college counselors, and indirectly affects the quality and development of talent cultivation for college students. Objective To explore the relationship between job stress, job crafting, and job burnout among college counselors, and to test the mediating role of job crafting between job stress and job burnout, in order to take targeted measures to alleviate job stress and job burnout of college counselors, reduce associated health risks, and improve the effectiveness of higher education. Methods An anonymous questionnaire survey was conducted among 400 counselors from social network communication groups by convenience sampling. The Counselor Work Stress Scale, Job Crafting Scale, and Maslach Burnout Inventory-General Survey were used. Harman's single-factor method was used to evaluate common method bias in the survey data. One-way ANOVA was applied to test the difference in job stress, job crafting, and job burnout among college counselors by demographic characteristics, and chi-square test was used to analyze the difference in reporting job burnout. Partial correlation analysis was used to evaluate the correlation between selected variables. Structural equation modeling was used to analyze the relationship of job stress, job crafting, and job burnout among college counselors, and Bootstrap analysis was used to test if there was a mediating effect of job crafting on the relationship between job stress and job burnout. Results Of the 390 questionnaires recovered, there were 338 valid questionnaires (86.67%). Among the included subjects, the mean scores of job stress, job crafting, and job burnout were (2.70±0.62), (3.77±0.62), and (2.09±1.09), respectively. The positive rate of job burnout was 76.9% (260/338), with a positive rate of 72.8% in exhaustion dimension and 59.8% in cynicism dimension. There were significant differences in job crafting scores among the college counselors by different genders and professional titles (P<0.05). Female counselors had significantly higher job burnout scores and positive rates than male counselors (P<0.05). The partial correlation analysis showed that job stress, work load, school evaluation and expectation, and interpersonal relationship were positively correlated with job burnout (r=0.562, 0.442, 0.473, and 0.455, respectively, P<0.01), and negatively correlated with job crafting (r=−0.271, −0.169, −0.246, and −0.247, respectively, P<0.01); job crafting, cognitive crafting, relationship crafting, and task crafting were negatively correlated with job burnout (r=−0.447, −0.452, −0.366, and −0.340, respectively, P<0.01). The modified structural equation modeling indicated that job stress negatively affected job crafting (b=−0.348, P<0.001) and positively affected job burnout (b=0.454, P<0.001); job crafting negatively affected job burnout (b=−0.459, P<0.001), and played a partial mediating role in the relationship between job stress and job burnout, and the effect value was 0.160 (95%CI: 0.102, 0.230) that accounted for 26.10% of the total effect. Conclusion Job burnout among the college counselors is prominent. Job crafting presents an inhibitory effect on job burnout. Job stress indirectly affects the occurrence of job burnout by inhibiting the generation of job crafting.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Abstract Dry eye disease is a chronic ocular surface inflammatory disease caused by abnormal tear quality or quantity and decreased tear film stability due to various reasons, and often accompanied by ocular discomfort such as itching, dryness, foreign body sensation, and visual dysfunction, which can seriously affect the patient′s quality of life and visual quality if not intervened in time. With the change of social lifestyles, the increase of environmental pollution and the trend of population aging, dry eye disease has become the most common ocular surface disease besides refractive error. Currently, dry eye disease is widely recognized as a non-infectious immune-related inflammatory disease, but the signaling pathways involved in dry eye disease are poorly understood. Whether dry eye disease is caused by excessive tear evaporation, insufficient tear production, or mucin deficiency, the ocular surface tissues(cornea/conjunctiva) inevitably undergo pathological processes such as aberrant proliferation, squamous epithelial hyperplasia, initiation of corneal damage repair mechanisms, and reduction in the number of conjunctival goblet cells, whereas the Wnt/β-catenin pathway is known to have a wide range of biological functions and plays an important role in cell proliferation, differentiation, and stemness maintenance. Therefore, this review describes the pathogenesis and potential experimental therapeutic options of the Wnt/β-catenin signaling pathway in dry eye disease from this perspective, aiming to provide new targets for the treatment of dry eye disease and achieve the goal of controlling the disease progression from the root.

A retrospective analysis was conducted on three patients with primary myelofibrosis who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at Shanghai Zhaxin Traditional Chinese and Western Medicine Hospital from 2020 to 2023. They subsequently developed poor graft function. The patients received selected donor CD34 + cell boosts as salvage therapy. There were two male patients and one female patient, with a median age of 68 (39-69) years. The median time from allo-HSCT to the selected donor CD34 + cell boost was 83 (56-154) days. The median infusion of selected donor CD34 + cells was 7.67 (7.61-9.06) ×10 6/kg, with a CD34 + cell purity of 97.76% (96.50%-97.91%) and a recovery rate of 70% (42%-75%) . Hematological recovery was achieved in two cases. No acute GVHD was observed in any of the three patients. One case of moderate oral chronic GVHD was noted. Selected donor CD34 + cell boosts for the treatment of poor graft function after allo-HSCT in primary myelofibrosis was effective and no severe acute or chronic GVHD was observed.

Objective To establish a scientific training program that takes into account both anaerobic and aerobic training for pilots,and to explore the appropriate ratio of aerobic and anaerobic training.Methods According to the physical examination standards for pilots,a total of 16 healthy subjects aged 18-24 were selected from two batches.The two batches of subjects were trained with different aerobic and anaerobic ratios.Training period was 3 months.The changes in cardiopulmonary function of the subjects before and after training were evaluated using the cardiopulmonary function exercise testing system(CPET),and the changes in anaerobic capacity were evaluated using changes in strength as an indicator.Results After training,the weight load of the subjects in the two training programs,including barbell squats,leg flexion and hard pull,and barbell under 10RM and 3RM,was significantly increased(P<0.001),and there was no statistically significant difference in anaerobic strength growth between the two groups.The results of CPET showed that the maximum load,maximum heart rate,and respiratory quotient in the two groups were significantly increased after than before the training(P<0.01).The maximum load(Experiment group 1:29.12±19.69,Experiment group 2:72.00±46.24)and respiratory quotient(Experiment grouop 1:0.11±0.09,Experiment group 2:0.28±0.16)of the subjects in experiment group 2 before and after training were greater than those in experiment group 1.The difference was statistically significant(P<0.05).Conclusion The anaerobic and aerobic capacities of the subjects in the experiment group 2 are effectively improved,indicating that ratio of aerobic and anaerobic of the training scheme is better.

The establishment of an intelligent audit system for hospital medical insurance is crucial for standardizing irrational practices and curbing the unwarranted escalation of medical insurance costs. A tertiary hospital has developed comprehensive prescription review rules in terms of indications, nutritional risk assessments, pain score evaluations, drug sensitivity test results, and target patient populations. When using medical insurance funds for settlement, both systematic and manual reviews are conducted, and three-level intervention measures such as " prompt, review, and interception" are implemented based on prescription issues. After the system was put into use, the hospital′s in-process information system supervision mode shifted from the previous focus on prompts to focus on audits. The medical insurance intelligent audit system provided timely prompts and interventions, and the number of unreasonable medical insurance prescriptions and deductions from medical insurance sampling prescriptions significantly decreased ( P<0.001), while the number of medical insurance medication prescription audits increased ( P<0.001). The application of the intelligent medical insurance medication audit system has improved the efficiency of prescription auditing and ensured the rationality of the use of medical insurance funds.

Papaya, which is mainly cultivated in the southeastern region of China, is one of the four famous fruits in Lingnan. It is favored by people because of its edible and medicinal value. Fructose-6-phosphate, 2-kinase/fructose-2, 6-bisphosphatase (F2KP) is a unique bifunctional enzyme with a kinase domain and an esterase domain that catalyzes the synthesis and degradation of fructose-2, 6-bisphosphate (Fru-2, 6-P₂), an important regulator of glucose metabolism in organisms. In order to study the function of the gene CpF2KP encoding the enzyme in papaya, it is particularly important to obtain the target protein. In this study, the coding sequence (CDS) of CpF2KP, with a full-length of 2 274 bp, was got from the papaya genome. The amplified sequence of full-length CDS was cloned into the vector PGEX-4T-1 which was double digested with EcoR I and BamH I. The amplified sequence was constructed into a prokaryotic expression vector by genetic recombination. After exploring the induction conditions, the results of SDS-PAGE showed that the size of the recombinant GST-CpF2KP protein was about 110 kDa. The optimum IPTG concentration and temperature for CpF2KP induction were 0.5 mmol/L and 28 ℃, respectively. The purified sin[A1] gle target protein was obtained after purifying the induced CpF2KP protein. In addition, the expression level of this gene was detected in different tissues, and showed that the gene was expressed at the highest level in seeds and the lowest in pulp. This study provides an important basis for further revealing the function of CpF2KP protein and studying the involved biological processes of this gene in papaya.

OBJECTIVE: To investigate the clinical manifestations, biochemical abnormalities and pathogenic variants among children with Short/branched-chain acyl-CoA dehydrogenase (SBCAD) deficiency detected by neonatal screening. METHODS: A total of 2 730 852 newborns were screened from January 2016 to December 2021 with liquid chromatography tandem mass spectrometry. Suspected SBCAD deficiency patients were diagnosed by urine organic acid analysis and high-throughput gene sequencing analysis. The clinical, biochemical and genetic changes of the confirmed cases were analyzed, in addition with guidance for diet and life management, L-carnitine supplement, and survey of growth and intellectual development. RESULTS: Twelve cases of SBCAD deficiency were diagnosed, which yielded a prevalence of 1/227 571. The lsovaleryl carnitine (C5) of primary screening blood samples was between 0.6 and 2.1 µmol/L, all exceeded the normal range. C5/acety1 carnitine (C2) was between 0.02 and 0.12, with 6 cases exceeding the normal range. C5/propionyl carnitine (C3) was between 0.1 and 1.16, with 5 cases exceeding the normal range. Free carnitine (C0) was between 18.89 and 58.12 µmol, with 1 case exceeding the normal range. Three neonates with abnormal screening results were recommended to have appropriate restriction for protein intake and two were given L-carnitine. During follow-up, their C5 has ranged from 0.22 to 2.32 µmol/L, C5/C2 has ranged from 0.01 to 0.31, C5/C3 has ranged from 0.14 to 1.7. C5 or C5/C2 and C5/C3 were transiently normal in all patients except for case 8 during the neonatal screening and follow-up. C0 was 17.42 ∼ 76.83 µmol/L Urine organic acid analysis was carried out in 9 of the 12 cases, and 2-methylbutyroglycine was elevated in 8 cases. Urine organic acid analysis was carried out in 9 cases, and 2-methylbutyrylglycine was increased in 8 cases. Genetic analysis was carried out for 11 children, and in total 6 ACADSB gene variants were identified, which included 4 missense variants (c.655G>A, c.923G>A, c.461G>A, c.1165A>G), 1 frameshift variant (c.746del) and 1 nonsense variant (c.275C>G). Among these, the C.461G>A variant was unreported previously. The most common variants were c.1165A>G (40.9%) and C.275C>G (22.7%). The patients were followed up for 18 days to 55 months. Only one patient had mental retardation, with the remainders having normal physical and mental development. CONCLUSION SBCAD deficiency is a rare disease. The detection rate of newborn screening in this study was 1/227 571. Early intervention can be attained in most asymptomatic patients through neonatal screening. In this study, the common gene variants are c.1165A>G and c.275C>G.
