Objective: To investigate the epidemiological characteristics of epidemic encephalitis B in Huzhou City, Zhejiang Province from 2007 to 2023, so as to provide the evidence for formulating prevention and control measures for epidemic encephalitis B. Methods: Epidemic encephalitis B case data in Huzhou City from 2007 to 2023 were collected through the National Notifiable Disease Reporting System of the Chinese Disease Prevention and Control Information System. The temporal, regional and population distribution characteristics of laboratory-confirmed epidemic encephalitis B cases were analyzed using the descriptively epidemiological method. Results: A total of 49 laboratory-confirmed epidemic encephalitis B cases were reported in Huzhou City from 2007 to 2023, and the average annual incidence was 0.10/105, showing a significant downward trend (P<0.05). The epidemic encephalitis B cases were concentrated from July to August, and July was the peak month, with 40 cases accounting for 81.63%. There was a statistically significant difference in the average annual incidences of epidemic encephalitis B among counties (districts) (P<0.05). Nanxun District had the highest reported incidence, with an average annual incidence of 0.23/105. There were 30 male cases and 19 female cases, with a male-to-female ratio of 1.58∶1. The youngest case was 5 months old, and the oldest was 49 years old. The children under 15 years were in the majority, with 42 cases accounting for 85.71%. Most of the cases were scattered children, with 25 cases accounting for 51.02%. There were 22 cases with no vaccination history and 21 cases with an unknown vaccination history, accounting for 44.90% and 42.86% respectively. All cases presented with fever. Other main clinical symptoms included listlessness, drowsiness, vomiting and headache, with 47, 40, 33 and 29 cases respectively, accounting for 95.92%, 81.63%, 67.35% and 59.18%, respectively. Conclusions The incidence of epidemic encephalitis B in Huzhou City remained at a relatively low level from 2007 to 2023, with Nanxun District being the high-risk area and July being the peak month for disease incidence. Fever and listlessness were the predominant clinical manifestations. Strengthening vaccination for children under 15 years should be prioritized.

Objective: To examine the impact of temperature on the incidence of hand-foot-mouth disease (HFMD), so as to provide a basis for research on the impact of climate on HFMD. Methods: HFMD incidence data in Huzhou City, Zhejiang Province from 2010 to 2022 were collected from the Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System. Concurrent meteorological data were obtained from the Huzhou Meteorological Bureau. A distributed lag non-linear model (DLNM) was employed to analyze the impact of temperature on HFMD incidence. Results: A total of 65 059 cases of HFMD were reported in Huzhou City from 2010 to 2022, with incidence peaks occurring from April to July and from October to November. The 5th, 25th, 50th, 75th, and 95th percentiles (P5, P25, P50, P75, and P95) of daily average temperature were 2.5, 9.4, 17.8, 24.7, and 30.6 ℃, respectively. The results from the DLNM analysis revealed a non-linear relationship between daily average temperature and HFMD incidence, which exhibited an irregular "M" shape. The incidence peaks were observed at 6.5 ℃ (RR=1.596, 95%CI: 1.154-2.207) and 25.7 ℃ (RR=3.257, 95%CI: 2.614-4.058), respectively. The maximum single-day effect was observed at a daily average temperature of -6.2 ℃ at lag 0 day (RR=1.250, 95%CI: 1.100-1.420), while the minimum single-day effect was observed at a daily average temperature of 34.6 ℃ at lag 0 day (RR=0.881, 95%CI: 0.826-0.940). The impact of daily average temperature at P5 on the incidence of HFMD showed RR values greater than 1 at lag 0, 3, 27, and 30 days, but less than 1 at lag 9 and 12 days, with no significant cumulative lag effect. In contrast, for the daily average temperature at P95, the RR values less than 1 at lag 15, 18, and 21 days, with significant cumulative lag effects identified. Conclusions The incidence of HFMD in Huzhou City peaks from April to July and again from October to November. There exists a nonlinear relationship and lag effect between temperature and HFMD incidence, with particular attention drawn to the impact of extreme temperatures on the disease's onset.

Objective: To investigate the detection of natural infection with pathogens in rodents in Huzhou City, Zhejiang Province, so as to provide a basis for risk assessment and control of rodent-borne diseases. Methods: From August to September each year during the period of 2022-2024, urban residential areas, rural residential areas, key industries, farmland and cultivated land, forests, and shrublands in various counties (districts) of Huzhou City were selected as rodent surveillance sites. Rodents were captured using the trap night method. Following anesthesia, the rodents were euthanized by cervical dislocation. Species were identified based on morphological characteristics. Under sterile conditions, dissection was performed to collect liver, spleen, lung, and kidney tissues. These tissues were then mixed together, and detected for Hantavirus, Dabie bandavirus, Leptospira, and Orientia tsutsugamushi using fluorescence quantitative PCR. The detection rates of these natural infections with pathogens were analyzed across different rodent species, counties (districts), and habitats. Results: A total of 259 rodents were captured from 2022 to 2024, including Rattus norvegicus, Rattus tanezumi, Suncus murinus, Mus musculus, Leopoldamys edwardsi, Niviventer fulvescens, Rattus losea, and Apodemus agrarius. The dominant species were Rattus norvegicus (142 individuals) and Rattus tanezumi (59 individuals), collectively accounting for 77.61%. With the exception of Orientia tsutsugamushi, Hantavirus, Dabie bandavirus, and Leptospira were all detected, with detection rates of 5.02%, 1.93%, and 10.42%, respectively. Hantavirus and Leptospira were simultaneously detected in one Rattus norvegicus, yielding a mixed infection rate of 0.39%. The three pathogens were detected in rodents in Wuxing District, Nanxun District, Deqing County, Changxing County, and Anji County, with detection rates of 6.45%, 5.71%, 26.32%, 4.76%, and 24.00%, respectively. They were also detected in rodents in urban residential areas, rural residential areas, key industries, farmland, and forests, with detection rates of 28.57%, 21.57%, 10.91%, 12.50%, and 14.81%, respectively. Notably, all three pathogens were simultaneously detected in Rattus norvegicus, Rattus tanezumi, rural residential areas, and key industries. Conclusions Rattus norvegicus and Rattus tanezumi were identified as the dominant rodent species in Huzhou City. The detection of Hantavirus, Dabie bandavirus, and Leptospira, including instances of mixed infection. It is necessary to enhance surveillance and control measures targeting these key species and high-risk habitats.

Objective: To monitor the adverse events following immunization (AEFI) with combined attenuated live measles, mumps and rubella vaccines (MMR) in Huzhou City from 2015 to 2021, so as to provide insights into the implementation of the MMR immunization strategy. Methods: All AEFI caused by MMR immunization in Huzhou City from 2015 to 2021 were captured from the AEFI Monitoring Information Management System of the Immunization Planning System of Chinese Disease Control and Prevention Information System, and the incidence, clinical features and epidemiological features of AEFI were analyzed descriptively. Results: The reported incidence of AEFI caused by MMR immunization appeared a tendency towards a rise in Huzhou City from 2015 to 2021 (χ2trend=124.126, P<0.001). Totally 324 386 doses of MMR vaccines were immunized, and 317 cases with AEFI were reported, with an reported incidence rate of 9.77/104 doses. Following two-dose immunization, the reported incidence of AEFI caused by two-dose MMR immunization was significantly lower than by one-dose immunization (6.01/104 doses vs. 25.43/104 doses; χ2=113.692, P<0.001). The incidence rates of general reactions, abnormal reactions and coincidental events were 6.20/104 doses, 3.42/104 dose and 0.15/104 doses, respectively. Fever and allergic rash were predominant clinical manifestations of AEFI, and no vaccine quality accident, inoculation accident or psychogenic reaction were reported. There were 246 (77.60%) cases with AEFI within 24 hours following vaccination, and among children with AEFI, there were 173 boys (54.57%), and 200 children (63.09%) age ages of less than one year (63.09%). AEFI was reported in each quarter, and 99 cases (31.23%) were reported in the fourth quarter. The largest number of children with AEFI was reported in Wuxing District (78 cases, 24.61%). Conclusions The safety of MMR vaccination is high in Huzhou City. General reaction is the predominant AEFI, which mainly occurs within 24 hours following vaccination. Two-dose MMR vaccination does not increase the risk of AEFI.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Scoliosis seriously affects the physical and mental health of children and adolescents. Without timely screening and intervention,it will lead to increased deformity,decreased labor capacity,cardiopulmonary complications,back pain and even paraplegia. This article reviews screening and intervention strategies for scoliosis at home and abroad. It concludes that there is lack of scoliosis screening in children and adolescents in China,and the screening results are difficult to compare horizontally because of the significant differences between strategies. It is suggested that scoliosis screening should be included in school healthcare work and formulate strategies with higher accuracy and safety. At the same time,three-dimension technology has good prospects in scoliosis screening and intervention,which is worthy of further development.

Objective: To understand the epidemiological characteristics and differences of HIV-positive cases among 15-24 years old in Jiaxing city and provide evidence for the development of targeted prevention and control measures. Methods: A descriptive epidemiological method was used to analyze the data of HIV cases aged 15-24 reported in Jiaxing from 1999 to 2018. Results: A total of 375 cases of young HIV were reported in 1999-2018, with an average age of 21.29±1.90 years, of which 42 were students. The ratio of male to female was 2.47∶1. The proportion of foreign household registration was higher (76%, 285 cases). The proportion of off-campus youth cases in total cases showed a downward trend(χ2=8.26, P=0.00), but the proportion of student cases showed an upward trend(χ2=15.73, P<0.01). Off-campus youth cases were mainly heterosexual transmission(59.16%, 197 cases), and the students’ cases were mainly homosexual transmission(88.10%, 37 cases). There were significant differences in gender, age, household registration, education level, route of transmission, late detection, CD4 level and source of detection among students and off-campus adolescents(P<0.05). Conclusion The prevalence of AIDS in adolescents and students is worthy of attention. The characteristics of adolescents inside and outside the school are different. Targeted prevention measures should be taken to reduce the harm of AIDS to young people.

AIM: To investigate the expression and significance of MAPK-interacting kinase-2 ( Mnk2 ) and eukaryotic initiation factor 4E ( eIF4E) in the patients with resected esophageal squamous cell carcinoma ( ESCC ). METHODS:The protein expression of Mnk2 and eIF4E in ESCC tissues (98 cases) and normal esophageal tissues (20 cases) were assessed by immunohistochemistry (IHC), and their correlations with clinicopathological features were statisti-cally analyzed.RESULTS:The over-expression rate of Mnk2 and eIF4E was 68.4%(67/98) and 61.2%(60/98), re-spectively.The expression of Mnk2 had a positive correlation with eIF4E (P<0.05).Clinicopathologic analysis showed that Mnk2 expression was significantly correlated with T classification ( P<0.05 ) and clinical stage ( P<0.05 ) .CON-CLUSION:The over-expression of Mnk2 was significantly related to the tumor invasive depth , TNM stages and expression of eIF4E in ESCC.Expression of Mnk2 and eIF4E may have a cooperative formation mechanism in the development of ESCC.
