Objective To evaluate the short-term effects of comprehensive health management interventions for stroke high-risk population screening on the prevention and treatment of ischemic stroke, and to provide reference and basis for improving and exploring health management and prevention strategies for stroke high-risk population. Methods From 2018 to 2022, 13 community health service centers in Jiading District, Shanghai were selected in the present study. Based on information push platform, stroke risk assessment and health intervention follow-up were conducted for community residents through convenience sampling. The residents were divided into a full course intervention group (intervention group) and a routine intervention group (control group) according to different health intervention measures and forms. The incidence of ischemic stroke in the two groups of survey subjects was tracked within 36 months. Results A total of 52144 subjects were included in the study. The total number of patients in the full course intervention group was 14227, with an incidence density of 577.32/100 000 (556.49/100 000-598.12/100 000), which was lower than that of the conventional intervention group (37 917), with an incidence density of 1 485.47/100 000 (1 464.99/100 000-1 505.94/100 000) (χ²=2490.212, P<0.001). The relative risk of the full course intervention group was 0.39, and the relative risk of stroke risk factors in the full course intervention group from low to high was 0.33, 0.43, 0.45, and 0.49, respectively. The incidence density of males in the full course intervention group was 660.76 (627.46/100 000 - 694.05/100 000), with a relative risk of 0.43, and the incidence density of female patients was 509.71/100 000 (483.37/100 000 - 536.05/100 000), with a relative risk of 0.35. The overall incidence density of the population under 62 years old gourp, 62-75 years old group and over 75 years old group was 197.45/100 000 (173.09/100 000 -221.80/100 000), 608.36/100 000 (580.19/100 000-636.54/100 000), and 1 025.06/100 000 (958.51/100 000-1 091.61/100 000), with relative risks of 0.51, 0.44, and 0.38, respectively. Conclusion Comprehensive health management measures can effectively reduce the short-term risk of ischemic stroke, and should be further promoted and improved to enhance the effectiveness of stroke prevention and control.

Objective:To investigate the efficacy of oral folic acid intervention in lung cancer patients with radiation esophagitis (RE) caused by concurrent chemoradiotherapy.Methods:In this randomized, controlled, single-center clinical trial, a total of 82 patients with stage N 2-N 3 lung cancer including small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) admitted to the Affiliated Cancer Hospital of Guizhou Medical University from June 2022 to October 2023 were prospectively included. All enrolled patients were randomly divided into the experimental group (folic acid group) and control group according to 1 vs. 1 of simple random method, and patients in both groups were required to receive radiation therapy for lung lesions and mediastinal metastatic lymph nodes [≥2 cycles of chemotherapy were completed during the same period of radiotherapy (≥40 Gy / 20 F) or targeted drugs were given simultaneously]. The severity of RE was evaluated using the modified common terminology criteria for adverse events criteria of the National Cancer Institute in both groups weekly at the onset of radiation esophagitis symptoms and thereafter until 1 week after the end of radiotherapy. Conventional treatment of RE was delivered according to the grading criteria of the Radiation Therapy Oncology Group. Patients in the folic acid group were given with folic acid tablets 30 mg/d orally at the beginning of radiotherapy until the end of radiotherapy, while those in the control group did not receive any drug intervention. The onset time, severity and duration of RE, and changes in the severity of esophageal toxicity after conventional treatment were recorded and analyzed. Serum folate value, serum vitamin B 12 value and homocysteine value were measured before and after radiotherapy. For continuous quantitative variables, independent sample t-test or independent sample rank-sum test was used for comparison among different groups. For categorical data, Chi-square test or Fisher's exact probability method was used for comparison among different groups. Results:During the observation period, no grade 4 or above RE was reported between two groups. The incidence of grade 0, 1, 2 and 3 RE in the folic acid and control groups was 10% (4/40) and 5% (2/41), 70% (28/40) and 42% (17/41), 15% (6/40) and 51% (21/41), 5% (2/40) and 2% (1/41), respectively. The differences were not statistically significant between two groups ( P=0.456). However, the incidence of grade 0-1 RE in the folic acid group was significantly higher than that in the control group ( Z=2.72, P=0.006). The median time of RE in the folic acid group and control group was 12 d (range 7-52 d) and 15 d (range 11-56 d) after the start of radiotherapy, respectively, with no statistically significant difference ( χ2=-0.75, P=0.456). However, median duration of the individual's most severe RE was 12 d (range 4-36 d) and 21 d (range 7-38 d) in the folic acid group and control groups, respectively, and the differences were statistically significant ( χ2=2.10, P=0.039). In the folic acid group, the grades of swallowing with pain and dysphagia were significantly declined after folic acid intervention, especially at 2 weeks after the occurrence of RE ( P=0.001, P=0.002). The remission rate of RE after 1 week in the folic acid group was higher than that in the control group, and the difference was statistically significant ( χ2=7.36, P=0.012). Conclusion:Oral intake of folic acid during concurrent chemoradiotherapy for lung cancer cannot reduce the incidence of RE, but it may reduce its severity, shorten the duration of the most severe RE in individuals, and have a certain protective effect.

Objective:To analyze the changes and significance in clinical cardiac indicators of early cardiac myocardial dysfunction and cardiac substructure dose during conventional radiotherapy for N 2-N 3 non-small cell lung cancer (NSCLC) with mediastinal lymph node metastases. Methods:The data of 34 NSCLC patients with lymph node metastases in regions 4-8 admitted to the Affiliated Cancer Hospital of Guizhou Medical University from June 2022 to August 2023 were observed and analyzed. All patients were treated with volumetric modulated arc therapy with a prescribed dose of 60-70 Gy. Cardiac troponin T (cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were measured at 6 time points: within 1 week before radiotherapy ( t0); when the cumulative radiotherapy dose reaches 20 Gy ( t20), 40 Gy ( t40), 60 Gy ( t60) during radiotherapy; within 1 week after radiotherapy ( tp); 1 month after radiotherapy( tp1). Left ventricular global longitudinal strain (LVGLS) and left atrial global longitudinal strain (LAGLS) were assessed at 4 time points: t0, t40, tp and tp1, respectively. The changes in cardiac indicators at different time points during radiotherapy and their correlation with substructure doses were analyzed using analysis of variance, linear regression analysis, and Pearson correlation. Results:The correlation between cardiac substructure dose and mean heart dose (MHD) in the study cohort in the descending order was as follows: left ventricle ( B=0.43, P<0.001), right ventricle ( B=0.37, P=0.002), left atrium ( B=0.16, P<0.001), and right atrium ( B=0.15, P=0.001). There were significant differences in the changes of LVGLS and LAGLS across different time points ( F=3.13, P=0.029; F=17.18, P<0.001). At 1 month after radiation, LAGLS was significantly decreased compared to pre-radiation levels ( P=0.009), whereas no significant difference was observed in LVGLS ( P=1.000). No significant differences were observed in the changes of cTnT and NT-proBNP across different time points (all P>0.05). Significant correlations were identified between cTnT and right ventricle mean dose at t40 ( r=0.38, P=0.025), as well as between NT-proBNP and right atrium mean dose at t60 and tp ( r=0.54, P=0.001; r=0.41, P=0.016). Conclusions:At present, there is no significant difference between the sensitive serum markers of myocardial injury and LVGLS in detecting early myocardial injury. LAGLS may hold substantial clinical value. There is uncertainty about radiation injury and repair of various cardiac substructures.

Objective:To identify the strengths and weaknesses of hospital development through the application of individual scientific research performance assessment, thereby providing a basis for the formulation of science and technology policies.Methods:We established a research performance assessment system and conducted research performance assessments across the hospital for three consecutive years. The assessment results were analyzed in-depth, utilizing the Kruskal-Wallis test to determine if there were differences in the overall level of assessment scores between years and series; the Mann-Whitney test to analyze differences between the promoted and non-promoted groups; the χ2 test to analyze whether age, degree, gender, and maternity situations affected assessment grades. Results:From 2020 to 2022, the individual scientific research performance assessment scores showed an overall upward trend, with the average per capita assessment score increasing significantly from 35.26 points in 2020 to 74.04 points in 2022. There were statistical differences in the assessment scores of different professional titles, indicating that the senior professionals > the associate senior professionals > the intermediates. There was no significant difference between the promoted and non-promoted groups. Additionally, age, degree, gender, and maternity factors affected assessment grades.Conclusions:It has been preliminarily established that the assessment of individual scientific research performance can effectively steer the scientific innovation activities of researchers, and play a positive role in enhancing the overall scientific research strength. The findings from the data analysis indicate that the hospital is expected to continuously enhance its scientific research performance by focusing on newly recruited doctoral personnel, establishing a system of support and guidance, and providing preferential support to female researchers. The assessment results serve as a " benchmark" for management departments and provide data-driven insights for the development of science and technology policies.

Objective Explore the impact of long-term blood glucose fluctuations and blood glucose control on the stroke incidence in patients with type 2 diabetes mellitus(T2DM).Methods An observa-tional cohort of patients with T2DM was established based on"Shanghai Community Chronic Disease Health Management Service Objects"on October 1st,2018.Follow-ups were conducted every three months,and fasting blood glucose(FBG)were tested at each visit.Basic epidemiological data were collected via the Shanghai Community Health Management Information Platform or survey questionnaires,and stroke incidents were gathered via the"Shanghai Cardio-Cerebrovascular Event Monitoring System".The first reported stroke incident within the observation period was considered.The observational deadline was December 31st,2021.Standard deviation of FBG was used to evaluate blood glucose fluctuation and FBG control rate was used to reflect blood glucose control status.Cox Proportional Hazards Model was utilized to analyze the impacts.Results The cumulative observation time was 91,826.1 person-years for the study,in which there were 1785 cases of stroke events observed,implying a cumulative incidence of 5.73%and incidence rate of 1943.9/100000 person-years.The mean number of follow-ups(10.29±3.07)per patient was recorded.The details of the stroke cases were as follows:transient ischemic attacks(n=111,6.22%),non-lacunar brain infarctions(n=754,42.24%),lacunar brain infarctions(n=798,44.71%),intracerebral hemorrhages(n=80,4.48%),non-intracerebral hemorrhages(n=8,0.45%),subarachnoid hemorrhages(n=12,0.67%),and unclassified strokes(n=22,1.23%).After excluding subjects with less than five follow-ups,the Cox Proportional Hazards Model suggested that increased standard deviation of FBG was an independent risk factor for the first stroke incident,and an increased blood glucose control rate was an independent protective factor.Both the standard deviation of FBG and the blood glucose control rate were not correlated with stroke recurrence.Conclusion Long-term blood glucose fluctuations and blood glucose control can predict the risk of a first stroke in patients with T2DM.The relationship between blood glucose fluctuations,blood glucose management,and stroke recurrence requires further studies.

Objective To investigate the prevalence of canine Leishmania infections in villages endemic for visceral leishmaniasis in Xin’an County, Luoyang City, so as to provide insights into visceral leishmaniasis prevention and control. Methods All dogs were captured from Huzhanggou Village, Xin’an County, Luoyang City in August 2020, where local cases with visceral leishmaniasis lived. The basic characteristics of dogs were collected, and venous blood was collected via the ear or neck veins of dogs. The serum anti-Leishmania antibody was detected using the rk39 immunochromatographic test and Leishmania nucleic acid was detected using PCR assay, and the prevalence of Leishmania infection was estimated in dogs. Results A total of 133 domestic dogs were captured from Huzhanggou Village, with a median age of 18.0 (28.5) months. The sero-prevalence of anti-Leishmania antibody was 24.81% (33/133) and the prevalence of a positive PCR assay was 14.29% (19/133) in dogs. The median ages of Leishmania-infected and uninfected dogs were 24.0 (36.0) months and 12.0 (18.0) months, respectively (U = 872.000, P = 0.000), and the prevalence of Leishmania infection was 55.56% (5/9) in “mangy dogs” and 24.19% (30/124) in asymptomatic dogs (χ² = 2.793, P = 0.095). Conclusions There are a large number of asymptomatic dogs with Leishmania infections in Xin’an County, Luoyang City, with a high transmission risk of visceral leishmaniasis. Timely prevention and control measures are required to control the spread of visceral leishmaniasis.

Objective To learn customer satisfaction for health management centers at public hospitals in Hangzhou. Methods From July to September 2015, 660 customers from the health management centers of 6 public hospitals in Hangzhou were randomly selected for questionnaire survey. The survey included their satisfaction for the technical attitude, service content design, waiting time, environment facilities, management regulations, and service charges. Univariate analysis was carried out on the satisfaction scores of customer demographics. Two-class logistic regression was used to analyze the factors affecting customer satisfaction. Results The average customer satisfaction score was 3. 62 ± 0. 55. Their satisfaction with technical attitude, service content design, environmental facilities and management regulations was higher. They were less satisfied with waiting time(3. 20 ± 0. 85) and service charge(3. 36 ± 0. 71). Conclusions Overall satisfaction of customers for such centers is high. In the future, we should further strengthen the information management and procedures of these centers, and link health management services with commercial insurance, for less economic burden on the people.

OBJECTIVETo detect potential mutation of iduronate-2-sulfatase (IDS) gene in a family affected with mucopolysaccharidosis type Ⅱ (MPS Ⅱ).

METHODSFor the proband and his unaffected mother, the whole coding sequence of the IDS gene was analyzed with PCR and bidirectional Sanger sequencing.

RESULTSA novel splicing mutation, c.709-1G>A, was detected in the proband, for which his mother was heterozygous.

CONCLUSIONThe c.709-1G>A splicing mutation of the IDS gene is probably causative for the MSP Ⅱ in the proband. Prenatal diagnosis for the mutation may avoid birth of further child affected with this disease.
