ObjectiveTo analyze the epidemiological characteristics and trends of hand-foot-mouth disease (HFMD) in Hangzhou, so as to provide an evidence for developing effective prevention and control measures and evaluating the control effects. MethodsThe incidence data of HFMD in Hangzhou were collected from the Infectious Disease Reporting Information Management System of China Information System for Disease Control and Prevention. Descriptive epidemiology was applied to analyze the temporal, spatial and demographic distribution characteristics and etiology monitoring results of HFMD cases in Hangzhou from 2010 to 2023. Joinpoint regression model was used to analyze the trends of incidence rate of HFMD. Furthermore, circular distribution method was utilized to calculate the incidence peak of HFMD. ResultsFrom 2010 to 2023, the average annual reported incidence rate of HFMD in Hangzhou was 138.85/100 000, the proportion of severe cases was 0.04%, the mortality rate was 0.01/100 000, and the case fatality rate was 5.30/100 000. Both the total incidence rate and the incidence rate by sex showed an increasing trend. The annual reported incidence rate in males (158.72/100 000) was higher than that in females (117.61/100 000). The reported incidence rate showed a significant seasonal characteristic, with summer being the peak of epidemic. The results of surveillance samples suggested that the prevalence of HFMD in Hangzhou is characterized by the co-existence of multiple pathogens, with EV-A71 and CV-A16 being the dominant pathogens in the previous years and CV-A6 being the dominant pathogen since 2018. The proportion of EV-A71 in severe cases (77.19%) was higher than that in ordinary cases (15.37%), in addition, its proportion in ordinary cases, severe cases, and fatal cases all showed a decreasing trend. ConclusionThe incidence rate of HFMD in Hangzhou is still high, so it’s still necessary to continue to strengthen the prevention and control measures for key populations. In recent years, CV-A6 has been the main prevalent pathogen in Hangzhou. Further efforts in pathogen detection and analysis should be enhanced in the future.

Descriptive epidemiological methods were used to analyze the epidemiological characteristics of the local cluster of COVID-19 in the logistic park of Yuhang District in Hangzhou in March 2022. The cluster epidemic was detected by a case who actively visited the fever clinic. The epidemic lasted for 8 days, and a total of 58 cases (53 workers, 2 students, 1 farmer, 1 teacher and 1 unemployed) were found, including 40 males and 18 females. The age was (33.29±12.22) years. There cases were mainly in Yuhang District (48 cases, 82.77%) and Shangcheng District (7 cases, 12.07%) of Hangzhou. The real-time regeneration number peaked at 2.31 on March 10 th and decreased to 0.37 on March 15 th. The sequencing result of the indicated case was 100% homologous with the sequence uploaded from South Korea on March 4 th, 2022.

Objective:To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients.Methods:Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control.Results:Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95% CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95% CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern ( OR=0.71, 95% CI: 0.52-0.98) and fruit-aquatic products-potato patterns ( OR=0.71, 95% CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns ( OR=0.60, 95% CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern ( OR=1.41, 95% CI: 1.03-1.94; OR=1.68, 95% CI: 1.13-2.51) and egg-milk-bean pattern ( OR=1.75, 95% CI: 1.25-2.46; OR=1.56, 95% CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q2 group), egg-milk-bean pattern ( Q3 group)" was higher ( OR=6.79, 95% CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q3 group), egg-milk-bean pattern ( Q2 group), oil-salt pattern ( Q2 group)" had higher control rate of 2 h PBG ( OR=12.78, 95% CI: 1.26-130.05, P=0.031). Conclusions:A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.

Non-neonatal tetanus is an acute, specific, toxic disease in patients over 28 days of age, characterized by continuous rigidity and paroxysmal spasms of the skeletal muscles throughout the body caused by the intrusion of Clostridium tetani through skin or mucosal membrane into the body and reproducing in anaerobic environments to produce exotoxins. The mortality rate of severe patients is close to 100% without medical intervention. Even with aggressive comprehensive treatment, the global mortality rate remains at 30%-50%, making it a potentially fatal disease. In order to standardize the diagnosis, treatment and prevention of non-neonatal tetanus, based on "Regulation for Diagnosis and Treatment of Non-neonatal Tetanus (2019 Edition)", experts have revised this regulation according to clinical practice and recent research progress in this field to guide medical institutions in the prevention and control of non-neonatal tetanus. This article interprets the key points and basis for updating the 2024 edition regulation to guide clinical implementation and application.

Objective:To quantify cerebral cortical and deep gray matter atrophy in patients with multiple sclerosis (MS) and explore its correlation with impairment in domains of cognitive function.Methods:Twenty patients with MS and 16 healthy controls (HC) matched for age, sex, and education level were included. Using FreeSurfer software, based on 3D-MRI technology, the differences in cortical thickness and deep gray matter volume between the two groups were comparatively analyzed. A neuropsychological scale that included six domains of cognitive function was scored on both study groups to analyze the correlation between cortical thickness and volume of deep gray matter in MS patients with impairment in cognitive function domains.Results:Impairment in domains of cognitive function: cognitive impairment was present in 60% MS patients in this study, mainly manifesting as impairment of verbal memory, verbal fluency, visuospatial memory, and information processing speed function (all P<0.05). Of these, the majority had impaired visuospatial memory function (55.0%), and the least number of patients had impaired information processing speed (15.0%). Changes in cortical thickness: compared with the HC group, the MS group showed that cortical atrophy was mainly concentrated in the frontoparietal region, including significant thinning of cortical thickness in the left inferior parietal gyrus, right superior frontal gyrus, and the right superior parietal gyrus (all P<0.05). Among them, atrophy of the left inferior parietal gyrus was significantly positively correlated with the impairment of verbal memory, verbal fluency, and information processing speed (all P<0.05). There was a significant positive correlation between the right superior frontal gyrus atrophy and verbal memory, verbal fluency, and visuospatial memory impairment (all P<0.05). Changes in deep gray matter volume: compared with the HC group, deep gray matter volume in the MS group decreased significantly in the bilateral thalamus, bilateral putamen, bilateral pallidum (all P<0.01), and right nucleus accumbens ( P<0.05). Among them, left thalamus atrophy was significantly positively correlated with visuospatial memory impairment ( r=0.45, P=0.046), and left putamen atrophy was both significantly positively correlated with visuospatial memory ( r=0.45, P=0.047) and information processing speed impairment ( r=0.50, P=0.026). Conclusions:Early structural brain changes in MS are dominated by gray matter atrophy. Deep gray matter is more prominent than cortical atrophy.

Objective:To analyze the prognostic outcomes of 1 147 patients who underwent liver transplantation at Qingdao University Affiliated Hospital and to summarize measures to enhance the efficacy of liver transplantation.Methods:A retrospective analysis was conducted on the clinical and follow-up data of 1 147 liver transplant patients at Qingdao University Affiliated Hospital.Results:The overall postoperative 1-, 3-, and 5-year survival rates for the 1 147 liver transplant patients were 87.20%, 73.40%, and 65.60%, respectively. The survival rates for benign disease liver transplant recipients were 88.01%, 84.98%, and 81.39% at 1, 3, and 5 years post-transplant, respectively, compared to recipients transplanted for malignancies of 78.11%, 64.41%, and 60.06% (all P<0.001). Among the mid vs more recent period, patients' 1-year and 3-year postoperative survival rates were 84.20%, 70.80% vs 90.50%, 71.70%, respectively,significantly in favor of recently enrolled patients ( P=0.022). In the complex surgery group, patients' 1-, 3-, and 5-year survival rates were 82.70%, 65.50%, 56.70%, while in less complicated group, it was 89.00%, 76.50%, 69.20% ( P<0.001). The primary causes of death for benign disease recipients were multi-organ failure (4.1%), while in recipients with malignant disease primary cause of death was tumor recurrence (23.7%). Postoperative complications included primary graft dysfunction, delayed graft function recovery, portal vein thrombosis, hepatic artery thrombosis, biliary stricture, post-transplant lymphoproliferative disorder, and graft-versus-host disease, with occurrence rates of 1.05%, 6.89%, 1.92%, 0.44%, 2.00%, 0.61%, and 0.44%, respectively. Conclusions:With the continuous improvement in surgical techniques and perioperative care levels, the 3-year survival rate of recipients at our center has increased. Malignant diseases and complex liver transplantation remain crucial factors affecting recipient prognosis, highlighting the need to further enhance comprehensive treatment capabilities for patients with malignant diseases and complex surgeries.

Three recipients with portal vein thrombosis experienced insufficient blood flow to transplanted liver due to residual thrombus after thrombectomy during liver transplantation. Alternative measures posed significant risks or technical challenges. To promptly restore blood flow, intraoperative intervention was performed via round ligament of donor liver for managing residual portal vein thrombus. Balloon dilation and vascular stenting effectively relieved local stenosis. After intervention, portal vein flow rate and volume fulfilled the standards and function of transplanted liver recovered smoothly. Follow-ups revealed unobstructed stents and no new thrombus formation. This simple, safe and efficacious technique has not been previously reported in the literature.

Objective:To study the epidemic characteristics and spatio-temporal distribution of scrub typhus in Hangzhou City.Methods:The case information of scrub typhus in Hangzhou City from 2010 to 2022 was collected through the Infectious Disease Surveillance and Reporting Information System of China Disease Prevention and Control Information System, and the incidence, time, population, and regional distribution characteristics of scrub typhus were analyzed. With street (township) as the unit, ArcGIS 10.2 software was used for global and local spatial autocorrelation analysis, SaTScan 10.1.2 software was used for spatio-temporal aggregation scanning.Results:From 2010 to 2022, a total of 362 cases were reported in Hangzhou City, with a median annual incidence of 0.260/100 000. The incidence showed a fluctuating upward trend year by year ( Z = 3.84, P < 0.001). The highest incidence was 0.528/100 000 in 2021 and the lowest incidence was 0.013/100 000 in 2010. The median time interval between onset and diagnosis was 7 days, ranging from 1 to 28 days. The peak incidence period was from September to November (52.49%, 190/362). There were 149 males (41.16%, 149/362) and 213 females (58.84%, 213/362). The age group of 60 - 69 years old had the highest number of cases, accounting for 32.32% (117/362). The majority of occupations were farmers (77.35%, 280/362). The top 3 regions with reported cases were Chun'an County (257 cases, 70.99%), Lin'an District (33 cases, 9.12%), and Jiande City (19 cases, 5.25%). Global spatial autocorrelation analysis showed that there was spatial aggregation in the incidence of scrub typhus in other years except 2015 - 2018 ( P < 0.05). Local spatial autocorrelation analysis showed that, except for 2015 and 2016, the incidence of scrub typhus in other years occurred in hot spots (high-high), which were all located in Chun'an County. The spatio-temporal aggregation analysis showed that the class Ⅰ cluster was centered around Jinfeng Township in Chun'an County, with a clustering period from December 2018 to November 2021, involving 22 townships. The class Ⅱ cluster was centered around Wanshi Township in Fuyang District, with a clustering period from December 2021 to November 2022, involving 14 streets (townships). Both of the two clusters were mountainous agricultural areas, with reported cases accounting for 38.67% (140/362). Conclusions:In Hangzhou City, the majority of scrub typhus cases are elderly female farmers, with a high incidence season in autumn, mainly occurring in agricultural areas in mountainous areas. It is recommended to carry out comprehensive prevention and control measures such as health education and personal protection for key populations, seasons and regions.

Objective:To explore whether miR-372 can affect the proliferation, migration and apoptosis of renal clear cell carcinoma (ccRCC) cell under different expression conditions, and to study the effect of miR-372 on PI3K/AKT/mTOR signaling pathway.Methods:ccRCC cell line (786-O) and normal renal epithelial cell line (HK-2) were selected to detect the expression level of miR-372 in 786-O cell and HK-2 cell by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR). The mimic group and negative control group were prepared by transfection with the mimic agent, and the inhibitor group and negative control group were prepared by transfection with the inhibitor. After stable transcription of cell lines was obtained, cell migration was detected by cell scratch assay, cell proliferation was detected by CCK8 method, and cell apoptosis was detected by flow cytometry, and the expression levels of proliferation and apoptosis related proteins and PI3K/AKT/mTOR signaling pathway-related proteins were detected by Western blotting. Measurement data were expressed as mean ± standard deviation ( ± s), and independent sample t-test was used for comparison between groups. Results:The expression level of miR-372 was decreased in 786-O cell. Overexpression of miR-372 inhibited the expression of proliferating cell nuclear antigen, promoted the expression of Bcl-2 and Caspase3, and reduced the phosphorylation level of PI3K/AKT/mTOR signaling pathway in 786-O cell.Conclusions:miR-372 can inhibit the migration and proliferation of 786-O cell, and promote cell apoptosis. In addition, miR-372 can inhibit the PI3K/AKT/mTOR signaling pathway.

Objective:To explore the application effect of continuous nursing based on hybrid electronic platform and fragmentation time in the out-of-hospital rehabilitation of patients with anterior cruciate ligament reconstruction.Methods:This was a randomized controlled study. From April 2020 to October 2021, a total of 90 patients undergoing anterior cruciate ligament reconstruction in Weifang People′s Hospital were selected as the research objects by convenience sampling. Forty patients from April to December 2020 were selected as control group, and 45 patients from January to October 2021 were selected as intervention group. The control group implemented routine discharge guidance and follow-up, while the intervention group was given continuous nursing plan based on the concept of hybrid electronic platform and fragmented time. Before operation and 1, 3 and 6 months after operation, the knee range of motion and Lysholm score of patients in the two groups were analyzed. At 1, 3 and 6 months after operation, the rehabilitation exercise compliance score, self-efficacy score and knee stability examination of the two groups were analyzed.Results:A total of 41 patients in each group completed the study. At 1 month after operation, the knee range of motion, Lysholm score, rehabilitation exercise compliance score and self-efficacy score of intervention group were (96.46 ±3.58) ° and (53.54 ± 6.57), (69.17 ± 6.27), (4.01 ± 0.38) points, respectively. In the control group, they were (89.02 ± 4.22)° and (45.02 ± 7.61), (56.78 ± 8.45), (3.61 ± 0.42) points. At 3 months after operation, they were (136.83 ± 4.30)° and (72.76 ± 4.96), (60.71 ± 5.87), (4.97 ± 0.32) points in the intervention group, (133.54 ± 3.58)° and (69.83 ± 6.65), (56.73 ± 8.57), (4.83 ± 0.45) points in the control group, respectively. At 6 months after operation, they were (139.39 ± 1.99)° and (85.61 ± 6.11), (57.71 ± 7.41), (6.58 ± 0.96) points in the intervention group, (138.29 ± 2.65)° and (81.80 ± 6.38), (47.90 ± 6.02), (6.35 ± 1.23) points in the control group, respectively. The knee range of motion, Lysholm score and rehabilitation exercise compliance score of the intervention group were better than those of the control group at 1, 3 and 6 months after operation, and the differences were statistically significant ( t values were 2.12-8.61, all P<0.05). The self-efficacy score of the intervention group was higher than that of the control group at 1 month after operation, and the difference was statistically significant ( t=4.57, P<0.05). Conclusions:The continuous nursing program based on hybrid electronic platform and fragmented time can improve the knee function of patients with anterior cruciate ligament reconstruction in the early postoperative period, improve the compliance of rehabilitation exercise and the level of early self-efficacy.
