Objective To analyze the incidence and mortality of acute viral hepatitis in China, project its trends from 2022 to 2030, and provide valuable insights for the prevention and control of viral hepatitis. Methods The incidence and mortality rates of acute viral hepatitis in China from 1990 to 2021 were extracted from the Global Burden of Disease 2021 database. The change rates and the estimated annual percentage change (EAPC) for each indicator were calculated. Additionally, an autoregressive integrated moving average (ARIMA) model was used to project the incidence and mortality of acute viral hepatitis in China from 2022 to 2030. Results From 1990 to 2021, the incidence rates of acute hepatitis A (AHA), acute hepatitis B (AHB), acute hepatitis C (AHC), and acute hepatitis E (AHE) in China all showed a declining trend (EAPC=−1.980%, −2.664%, −2.078%, −1.686%; P<0.05), with a particularly marked decrease in mortality (EAPC=−11.662%, −7.411%, −12.541%, −7.504%; P<0.05). According to ARIMA model projections, the incidence rates of AHA and AHB were expected to continue declining from 2022 to 2030, while the incidence rates of AHC and AHE were expected to rise. In 2030, the projected incidence rates of AHA, AHB, AHC, and AHE were 890.425/100000, 824.158/100000, 59.202/100000, and 300.377/100000, respectively. The mortality rates of AHA, AHC, and AHE were projected to remain stable from 2022 to 2030, while the mortality rate of AHB was expected to decline. In 2030, the projected mortality rates of AHA, AHB, AHC, and AHE were 0.002/100000, 0/100000, 0.004/100000, and 0.011/100000, respectively. Conclusions From 1990 to 2021, the overall incidence and mortality of acute viral hepatitis in China showed a downward trend. However, the incidence rates of AHC and AHE may present an upward trend in the future, which suggests that the government and relevant health authorities should adjust their prevention and control strategies in a timely manner.
ObjectiveTo systematically review the trend of tuberculosis among Chinese students. MethodsPubMed, Web of Science, EMbase, CBM, WanFang Data and CNKI databases were electronically searched to collect cross-sectional studies on the incidence and trend of tuberculosis among students in China from inception to August 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, meta-analysis was performed by using Stata 15.0 software. ResultsA total of 97 cross-sectional studies were included. The results of meta-analysis showed that: the overall incidence of tuberculosis among students in China was 18.63 per 100 000 persons. The incidence in the northwest, south, northeast, north, east, central, and southwest 46.81, 11.22, 24.38, 12.77, 12.03, 18.95, and 39.26 per 100 000 persons, respectively. The incidence among university students, senior high school students, junior school students, and primary school students 38.17, 33.84, 8.85, and 1.68 per 100 000 persons, respectively. ConclusionCurrent evidence shows that the incidence of tuberculosis among students in China is high. Among them, the incidence rate of tuberculosis in the central and western regions, universities and high school students is relatively high.

Objective To explore impact of climate change on aortic dissection and to put forward a new way about prediction and prevention of aortic dissection. Methods We retrospectively analyzed the characteristics of acute aortic dissection patients came from Hebei province in Fuwai Hospital between 2010 and 2016 year. Meanwhile, we collected monthly maximum temperature, minimum temperature, average temperature, average pressure, amount of rainfall, sunshine, humidity and other meteorological data. Generalized model was implied to explore climate change and the incidence of aortic dissection. Results A total of 1 121 acute aortic dissection patients from Hebei province were admitted in Fuwai Hospital during the period of 6 years. There were 774 patients were type A aortic dissection, and 347 patients were type B aortic dissection. The average age was 51.4±12.0 years. There were 873 males and 248 females. There were 889 (79.3%) patients with hypertension, 99 (8.83%) with Marfan syndrome. It was found that temperature, humidity and air pressure were all statistically significant for indication aortic dissection through single variable analysis (P<0.01). The temperature was only variable by one-way analysis of variance (P<0.01). The lowest temperature has the best predictive effect on the occurrence of aortic dissection. The relative risk was 1.02 with 95% confidence interval 1.02 to 1.03. Conclusion The change of climatic conditions can affect the occurrence of aortic dissection, and the lowest temperature is an important trigger factor for aortic dissection onset.
Objective To assess the midterm follow-up outcomes of total hip arthroplasty (THA) for the treatment of patients with juvenile-onset ankylosing spondylitis (JAS). Methods The clinical data of 81 patients (127 hips) with JAS (age≤16 years, JAS group) and 267 patients (391 hips) with adult onset ankylosing spondylitis (AAS) (age>16 years, AAS group) between January 2004 and March 2018 were retrospectively analysed. The baseline demographics, clinical, radiographic, and laboratory parameters were collected. Before operation and at last follow-up, the overall disease activity [Bath ankylosing spondylitis disease activity index (BASDAI)] and function status [Bath ankylosing spondylitis functional index (BASFI)], hip subjective score [Harris hip score (HHS)] and objective score [12-item short form health survey (SF-12), including physical component score (PCS) and mental component score (MCS)], and patient satisfaction for THA were reviewed. The major orthopedic complications, including periprosthetic infection, dislocation, periprosthetic fractures, and poor incision healing, were also recorded during the follow-up period. Results The comparison of preoperative baseline parameters showed that the body mass, body mass index, age of onset, age of surgery, disease duration, and the proportion of combined smoking history in the JAS group were significantly lower than those in the AAS group (P<0.05), the proportion of bilateral surgeries, proportion of uveitis, proportion of combined family history, C-reactive protein, albumin, and preoperative BASFI were significantly higher than those in the AAS group (P<0.05). Both groups were followed up. The follow-up time in the JAS group was 29-199 months, with an average of 113 months; in the AAS group was 35-199 months, with an average of 98 months. Incisions in both groups healed by first intention. During the follow-up period, there were 1 case of periprosthetic fracture, 1 case of dislocation, and 1 case of ceramic fragmentation in the JAS group, 1 case of periprosthetic infection and 6 cases of periprosthetic fracture in the AAS group. There was no significant difference in the incidence of complications between the two groups (P>0.05). At last follow-up, the BASDAI, BASFI, SF-12 MCS, SF-12 PCS, and HHS score of the two groups were significantly improved when compared with those before operation (P<0.05); but there was no significan difference in the difference of the above parameters before and after operation and the patient satisfaction between the two groups (P>0.05). Conclusion The midterm follow-up outcomes of THA for the treatment of JAS patients were reliable. A low age at disease onset did not exert a significant negative effect on THA reconstruction for the treatment of ankylosing spondylitis.
