ObjectiveTo construct a competency model for "dual-qualified" teachers in vocational undergraduate rehabilitation therapy programs based on the World Health Organization's rehabilitation competency framework (RCF) and relevant domestic and international standards, and explore the training pathways for rehabilitation therapy teachers in China. MethodsLiterature analysis and comparative research methods were employed to systematically review RCF, physiotherapist-education-framework-FINAL, the Minimum-Standards-for-the-Education-of-Occupational-Therapists, and the "dual-qualified" teacher standards in vocational education for China. Focusing on the characteristics of vocational undergraduate talent cultivation, it took the integration of the "educator-clinical rehabilitation therapist" dual roles as its starting point, combining rehabilitation industry competence with educator standards as its basic principle, and using RCF as its foundational dimension. It then integrated advanced competency dimensions required of vocational undergraduate teachers to form a dimensional framework. Following the systematic curriculum development concept of the work process, the core activities of each dimension were designed by combining, improving and expanding the concept integration method, and describing the ability characteristics in a graded and progressive manner, to construct a model. ResultsThis model was guided by the core concepts of three types of values ​​and four types of professional beliefs. Vertically, it encompassed 28 activities across eight competency dimensions, including teaching practice, rehabilitation practice, digital literacy, professionalism, learning and development, management and leadership, applied research, and social service. Horizontally, it encompassed 53 corresponding competency characteristics across three advanced levels (beginner, intermediate and advanced). ConclusionThis model, through its vertical dimension design and horizontal progressive development, clearly describes the advancement of vocational undergraduate rehabilitation therapy teachers from newly hired teachers to backbone teachers and professional leaders. It not only aligns with the general requirements of the national standards for "dual-qualified" teachers in higher vocational colleges in China, but also incorporates an international perspective on rehabilitation education and practice, and possesses the characteristics of vocational undergraduate education that integrates multiple abilities and roles. At the theoretical level, it provides core theoretical support for establishing standardized and internationalized "dual-qualified" teacher standards for vocational undergraduate rehabilitation therapy programs in China; at the practical level, it serves as an "action map" for teacher professional development, assessment and evaluation, providing a key reference for constructing a systematic high-end skilled rehabilitation talent training system.

Objective:To analyze the epidemiological characteristics and natural focus distribution of marburg virus disease (MVD), and provide evidence for the prevention and control of MVD.Methods:A systematic literature retrieval was conducted, and descriptive epidemiological method was used to analyze the temporal, spatial, and population distributions of MVD as well as its natural hosts. The case fatality rate of MVD was evaluated through Meta-analysis, and the phylogenetic analysis of viral genomes was done by using software IQ-TREE 2.3.6.Results:Marburg virus has endemic spread in Africa and can be detected in various animals such as primates and bats. The positive rate is higher in Egyptian fruit bats, and the disease epidemic areas continue to expand. The human infections occur frequently. As of December 20, 2024, a total of 18 MVD outbreaks had been reported worldwide, resulting in 722 reported cases and 548 deaths. Meta- analysis showed a case fatality rate of about 65.19% (95% CI: 48.07%-80.50%). Populations are generally susceptible, with a higher proportion of the cases in miners and medical workers. Marburg virus specific antibody can be detected in populations and animals in some countries and regions where no cases have been reported in Africa, indicating the potential of virus transmission. Conclusion:The transmission capacity of Marburg virus shows no significant changes, but the areas affected by the virus transmission expands, indicating increased risk for MVD outbreak.

Objective:To develop and validate a risk prediction model for cognitive frailty in elderly patients with type 2 diabetes.Methods:A total of 483 elderly patients with type 2 diabetes who visited Tianjin First Central Hospital from June to December 2022 were selected using convenience sampling. They were randomly divided into a modeling group ( n=338) and a validation group ( n=145). Data were collected using a self-designed general information questionnaire, the Short-Form Mini Nutritional Assessment (MNA-SF), the Geriatric Depression Scale-15 (GDS-15), the Frailty Phenotype (FP), the Montreal Cognitive Assessment (MoCA), and the Clinical Dementia Rating (CDR). Logistic regression analysis was performed to identify the influencing factors. A cognitive frailty risk prediction nomogram model was constructed based on the results. The model was validated in the validation group, and its predictive performance and clinical applicability were evaluated using the area under the receiver operating characteristic curve ( AUC), calibration curve, and clinical decision curve analysis. A total of 483 questionnaires were distributed and all were returned as valid, resulting in a 100.0% response rate. Results:The prevalence of cognitive frailty in the 483 elderly patients with type 2 diabetes was 20.3% (98/483). Age, regular exercise, duration of diabetes, HbA1c levels, depression and nutritional status were identified as predictive factors in the model. The AUC of the model was 0.886, and the Hosmer-Lemeshow test showed a χ 2 value of 8.004 ( P=0.433). The optimal cutoff value was 0.335, and the accuracy was 89.0%. Conclusions:The prediction model demonstrates good fit and strong predictive performance, and can intuitively and easily identify elderly patients with type 2 diabetes who are at high risk of cognitive frailty, providing a reference for early screening and intervention.

Objective:To understand the epidemiological characteristics and incidence trend of severe fever with thrombocytopenia syndrome (SFTS) in China.Methods:The incidence data of SFTS in China from 2018 to 2021 were collected from Chinese Disease Prevention and Control Information System for a statistical and descriptive epidemiological analysis by using software such as Excel 2016, Joinpoint 5.0.2, SPSS 26.0, and GraphPad Prism 8.0, especially, the SFTS cases reported monthly by key provinces were analyzed.Results:From 2018 to 2021, a total of 8 835 SFTS cases were reported in 25 provinces and the annual incidence showed an upward trend. The distribution of SFTS cases showed clustering, but the cases were mainly sporadic ones. The cases began to increase in March, mainly occurred during April to October (96.79%,8 551/8 835), and peaked during May to July. The cases were mainly distributed in middle-aged and old farmers, and slight more cases were women. The average case fatality rate was 5.38%, which varied greatly with areas. The case fatality rate tended to increase with age.Conclusion:From 2018 to 2021, the epidemiological characteristics of SFTS in China remained stable, but the number of reported cases gradually increased and the distribution showed an expanding trend, to which close attention should be paid.

Abstract: Objective To analyze the epidemiological characteristics of reported cases of dengue fever in mainland China from 2019 to 2023 and provide a scientific basis for dengue prevention and control efforts. Methods The temporal, spatial, and population distribution characteristics, as well as the trends of dengue fever cases reported in the National Notifiable Disease Reporting System (NNDRS) of China were analyzed using software such as Joinpoint regression, SaTScan, and ArcGIS. Results From 2019 to 2023, a total of 43 095 cases were reported in China, with an average incidence rate of 61/100 000. The annual reported incidence rate fluctuated significantly (AAPC=-3.16%, 95%CI:-54.16%-91.47%), mainly concentrated in 2019 and 2023, accounting for 96.83% of the total reported cases over the past five years. All age groups were susceptible to the disease, with the 30 to <40 age group comprising 22.6% of cases. Cases were reported throughout the year, with a rapid increase starting in June and a peak period concentrated between August and October (n=34 780, RR=12.44, LLR=29 262.52, P<0.05). The epidemic was primarily characterized by imported cases leading to autochthonous transmission, with the majority of imported cases originating from Southeast Asia (86.56%), particularly from Cambodia (46.11%, 3 284 cases) and Myanmar (25.99%, 1 851 cases). The epidemic characteristics varied significantly across different years, with high risks of autochthonous transmission epidemics in Southwest, South, and Southeast China. High-risk local transmission were mainly distributed in Yunnan and Guangdong. The duration of the peak period of the epidemic was affected by the timeliness of early detection of local transmission, and the peak value of the epidemic was related to the effectiveness of prevention and control measures. The scale of the epidemic was influenced by the pressure of by cross-border transmission and the ability to implement local measures for dengue prevention and control. Conclusions With the increasing trend of global dengue transmission, the risk of autochthonous transmission of dengue in China is rising. It is recommended to strengthen proactive early outbreak surveillance, along with well preparation of personnel, technology, and resources for dengue prevention and control.According to autochthonous conditions, reasonable management and risk assessment of cross-border travelers should be explored to effectively.

Objective:To evaluate the effect of activation of splenic plasmacytoid dendritic cells (pDCs) on myocardial ischemia-reperfusion (I/R) injury in mice.Methods:The experiment was performed in two parts. Animal experiment Thirty-six SPF healthy male C57BL/6J mice, aged 10 weeks, weighing 22-27 g, were assigned to 3 groups ( n=12 each) using a random number table method: sham operation group (Sham group), myocardial ischemia group (MI group) and myocardial I/R group (MI/R group). The myocardial ischemia was induced by occluding the left anterior descending coronary artery for 40 min in MI group, while the model of myocardial I/R was established by occlusion of the left anterior descending coronary artery for 40 min followed by 1-h reperfusion in MI/R group. Following successful preparation of the model, 3 animals from each group were randomly selected, and their hearts were removed for determination of myocardial infarct size through a combination of TTC and methylene blue double staining. Another 3 animals from each group were randomly selected, and their hearts were removed for examination of pathological changes of myocardial tissues using HE staining. Blood samples were collected from the abdominal aorta of 6 mice left in each group for determination of plasma interferon alpha (IFN-α) concentrations by enzyme-linked immunosorbent assay. Then the animals were sacrificed and hearts were harvested for collection of cardiac perfusate (CP). Cell experiment Twelve SPF healthy male C57BL/6J mice, aged 10 weeks, weighing 22-27 g, were selected and the splenic pDCs were isolated using anti-mPDCA-1 MicroBeads according to the manufacturer′s instructions (with a positivity rate of >85% for the isolated cells). The cells were divided into 4 groups: group pDCs stimulated by CP in Sham group (pDCs+ CP-Sham group), group pDCs stimulated by CP in MI group (pDCs+ CP-MI group), group pDCs stimulated by CP in MI/R group (pDCs+ CP-MI/R group) and pDCs stimulated by PBS group (pDCs+ PBS group). The CP in Sham, MI and MI/R groups and PBS were used to induce and culture pDCs for 8 h. Flow cytometry was employed to detect the expression of CD45 and co-stimulatory molecules CD80, CD86 and Major Histocompatibility Complex Ⅱ (MHC Ⅱ) on the surface of pDCs. The levels of IFN-α in the cell culture supernatant were determined using enzyme-linked immunosorbent assay. Results:Animal experiments Compared with Sham group and MI group, the percentage of myocardial infarct size was significantly increased, the concentrations of plasma IFN-α were increased ( P<0.05), and cardiomyocytes displayed evident vacuolar degeneration, severe myocardial fiber rupture, and infiltration of a substantial number of inflammatory cells in MI/R group. There was no significant difference in each parameter between Sham group and MI group ( P>0.05). Cell experiment Compared with pDCs+ CP-Sham group, the expression of CD80, CD86 and MHCⅡ was significantly up-regulated in pDCs+ CP-MI group ( P<0.05), and no significant change was found in the aforementioned parameters in pDCs+ CP-MI/R group ( P>0.05). The expression of aforementioned parameters was significantly up-regulated in pDCs+ CP-MI group as compared with pDCs+ CP-MI/R group ( P<0.05). Compared with pDCs+ CP-Sham group and pDCs+ CP-MI/R group, the concentrations of IFN-α in the cell culture supernatant were significantly increased in pDCs+ CP-MI group ( P<0.05). There was no statistically significant difference in the concentrations of IFN-α between pDCs+ CP-MI/R group and pDCs+ CP-Sham group ( P>0.05). Conclusions:The mechanism underlying myocardial I/R injury may be related to activation of splenic pDCs leading to the production of IFN-α following myocardial ischemia in mice.

Objective:To assess the feasibility of wavelet index (WLI) in monitoring the depth of sedation with propofol in pediatric patients.Methods:This was a prospective observational trial. One hundred and sixty-five pediatric patients, aged >1-12 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing elective surgery requiring general anesthesia with endotracheal intubation or laryngeal mask airway from July to December 2016 in our hospital, were divided into 11 age groups ( n=15 each): >1-2 yr group, >2-3 yr group, >3-4 yr group, >4-5 yr group, >5-6 yr group, >6-7 yr group, >7-8 yr group, >8-9 yr group, >9-10 yr group, >10-11 yr group, and >11-12 yr group. General anesthesia was induced by injection of propofol 3 mg/kg for more than 30 s. WLI and BIS values were recorded immediately before administration and at 30, 40, 50, 60, 90, 120, 180 and 240 s after the end of administration. If there were differences among age groups, age groups with no statistically significant differences were combined and re-grouped. Pearson linear correlation analysis and Bland-Altman consistency analysis were performed. Results:A total of 149 pediatric patients were actually included. There were no significant differences in BIS values between 4 groups aged > 1-5 yr and between 7 groups aged > 5-12 yr ( P>0.05). Regrouping was performed based on the aforementioned results, 4 groups of children aged > 1-5 yr were divided into > 1-5 yr group ( n=60), and 7 groups of children aged > 5-12 yr were divided into > 5-12 yr group ( n=89). WLI values and BIS values were significantly decreased at each time point after administration compared with immediately before administration in group aged > 1-5 yr and in group aged >5-12 yr ( P<0.05). The BIS values were the lowest at 60 s after the end of the administration, and the WLI values were the lowest at 120 and 180 s after the end of the administration in two groups ( P<0.05). There were no statistically significant differences between WLI values and BIS values at 90 s and 240 s after the end of the administration ( P>0.05), and there was statistically significant difference at the other time points in group aged > 1-5 yr ( P<0.05). There was no significant difference between WLI values and BIS values at 180 s and 240 s after the end of the administration ( P>0.05), but there were significant differences at the other time points in group aged > 5-12 yr ( P<0.05). The Pearson correlation coefficients between WLI values and BIS values were 0.61 and 0.56 in group aged > 1-5 yr and group aged > 5-12 yr, respectively ( P<0.001). Bland-Altman agreement analysis: In group aged > 1-5 yr and group aged > 5-12 yr, the 95% agreement limits were -0.484-0.621 and -0.551-1.015, respectively, and there were 4.6% (23/504) and 5.1% (40/777) of the points outside the 95% agreement limits, respectively, and both limits exceeded the clinically acceptable range. Conclusions:WLI is feasible for monitoring the depth of sedation with propofol in pediatric patients aged > 1-12 yr, but the accuracy is lower than BIS.
