Objective:To provide countermeasures and suggestions for the current operation and management of public hospitals by analyzing the impacts of COVID-19 on public hospitals′ operation.Methods:Collection of operation data of 44 public hospitals in Wenzhou from January to March in both 2019 and 2020. By means of descriptive analysis and financial analysis, we analyzed the impacts of the pandemic on the hospitals′ business, revenue and expenditure structure.Results:As of April 2020, even the outpatients visits and inpatient at Wenzhou public hospitals had significantly rebounded, and the downrange for the same periods of 2019 was as high as 23.12% and 17.37% respectively. April witnessed the total medical service revenue of 44 hospitals business totaled 17.44 billion yuan, down 15.43%from the previous year and up 17 percentage points compared to the decline in the first quarter(at 32.54%). As the pandemic moves into a normalized state for epidemic prevention and control, the recovery of medical business was slow, while expenditure of manpower costs and epidemic prevention costs had increased instead. Capital pressure would be the biggest pressure for most hospitals.Conclusions:The hospitals need to further strengthen their operation of fine management and cost control, for sustainable development. It is suggested that government departments should continue to increase effective investment in public health, reduce hospitals′ social insurance premiums in stages, further promote the implementation of online medical service pricing policies, especially Internet hospitals, and relax hospitals′ working capital loan access to ensure liquidity turnover.

Dengue viruses(DENV) are seriously affected by cell autophagy in intracellular replication,transmission between host,and the pathogenic mechanism.Here,the latest research progress of complex interplay between DENV and cell autophagy were reviewed in this paper.Autophagy,a cellular procedural protein degradation pathway generally possessed by all eukaryotes plays a key role in response to outside pressure and maintaining cellular homeostasis.This catabolic pathway also promotes cell survival against the invasion of pathogens such as various viruses.However,autophagy plays an opposite role in the replication of DENV.Autophagy not only provides a replication site for viruses to replicate,but also provides a source of energy for this process.Cell autophagy also participates in the pathogenesis of some DENV infection.In short,autophagy contributes to the replication of DENV.

Objective: To explore the spatial-temporal distribution and epidemic characteristics of hemorrhagic fever with renal syndrome (HFRS) in Hebei province from 2005 to 2016. Methods: Records of HFRS cases reported from each county in Hebei during January 2005 to December 2016 were collected from National Notifiable Disease Surveillance System (NNDSS). Global and local spatial association statistics were used to measure the spatial autocorrelation and software GeoDa 1.2.0. Software SaTScan 9.4.1 was used to analyze spatiotemporal clusters. Software ArcGIS 10.2 was used to visualize the yearly scan results. Results: In Hebei province, a total of 8 437 human HFRS cases reported from 170 counties with an annual incidence rate of 0.99/100 000 population during 2005-2016. The peak incidence season was spring. Global spatial autocorrelation analysis on the incidence of HFRS at county-level showed that the value of Moran’s I were all above 0 (P<0.05), indicating that the significant spatial cluster. The result of local indicators on spatial association (LISA) analysis revealed that identified hot spots were mainly in northeastern area, while cold spots were found in some counties of central and southern areas. Spatial-temporal scan detected that the primary cluster of HFRS incidence was mainly distributed in Qinhuangdao city and Tangshan city, including 11 counties (city/district): Beidaihe district, Haigang district, Funing district, Shanhaiguan district, Changli county, Lulong county and Qinglong Manchu autonomous county in Qinhuangdao city, and Qian’an city, Laoting county, Luanzhou city and Luannan county in Tangshan city (RR=39.64, P<0.001), during January-July in 2005. Conclusions There were significant spatial-temporal cluster of HFRS in Hebei from 2005 to 2016. The cluster areas of HFRS were mainly in northeastern Hebei, it is necessary to strengthen the prevention and control programs of HFRS in these areas.

Accurate classification of the acetabular injuries and appropriate treatment plan are great challenges for orthopedic surgeons because of the irregular anatomical structure of the acetabulum and aggregation of important vessels and nerves around it. Letournel-Judet classification system has been widely applied to classify acetabular fractures. However, there are several limitations, including incomplete inclusion of fracture types, difficulty in understanding and insufficient guidance for surgical treatment, etc. Serious complications such as traumatic arthritis are common due to wrong classification and diagnosis and improper selection of surgical strategy, which brings a heavy burden to the society and families. Three-column classification, based on anatomic characteristics, has advantages of containing more fracture types and being easy to understand, etc. To solve the problems existing in the diagnosis and treatment process based on Letournel-Judet classification, achieve accurate diagnosis and treatment of patients with acetabular fractures, and obtain satisfactory prognosis, the Orthopedic Trauma Emergency Center of Third Hospital of Hebei Medical University and the Trauma Orthopedic Branch of the Chinese Orthopedic Association organized experts from relevant fields to formulate the Expert consensus on the accurate diagnosis and treatment of acetabular fractures based on three-column classification ( version 2023) in terms of principles of evidence-based medicine. Based on the three-column classification, 15 recommendations were proposed, covering the diagnosis, treatment, complication prevention and management, etc, so as to provide reference for accurate diagnosis and treatment of acetabular fractures.
