Methods: Data of brucellosis cases and epidemiological investigation in Shaoxing City from 2005 to 2023 were collected from the Monitoring and Reporting Management System of the Chinese Disease Prevention and Control Information System. The epidemiological characteristics of brucellosis were descriptively analyzed, the trend in incidence of brucellosis was analyzed using average annual percent change (AAPC). Results: A total of 270 cases of brucellosis were reported in Shaoxing City from 2005 to 2023, with an average annual incidence of 0.29/105. The AAPC was 0.812%, with no significant changing trend (P>0.05). The incidence of brucellosis peaked from February to March, with 80 cases (29.63%). The reported cases were mainly distributed in Shangyu District (139 cases, 51.48%) and Shengzhou City (74 cases, 27.41%). There were 188 male cases and 82 female cases, with a male-to-female ratio of 2.29∶1. The cases were primarily concentrated in the age group of 40 to <70 years, with 205 cases accounting for 75.93%. Among these, 86 cases were reported in the 50 to <60 years of age group, accounting for 41.95%. The majority of the cases were farmers, with 187 cases accounting for 69.26%. The median interval from onset to diagnosis was 22.73 (interquartile range, 39.97) days, with a delayed diagnosis rate of 62.96%. Infections through breeding, selling and transporting cattle and sheep resulted in 164 cases (60.74%), and through buying and slaughtering resulted in 36 cases (13.33%). An outbreak of brucellosis was reported in Xinchang County in 2018, with three confirmed cases. Conclusions The incidence of brucellosis in Shaoxing City had no significant change from 2005 to 2023.

Objective To observe the effects of Ganlu Xiaodu Dan and its incomplete prescription on expressions of MiR-146a and TLR4 mRNA in RD cells infected by EV71. Methods With technique of cell culturing, Ganlu Xiaodu Dan therapy group, incomplete Qing prescription therapy group, incomplete Li prescription therapy group, normal cells control group, model control group and ribavirin control group were set, and tests for virus toxicity and medicine toxicity in cells were taken, then expressions of miRNA-146a and TLR4 mRNA in these RD cells 24 hours after intervention with medicine were detected. Results Compared with normal cells control group, miR-146a in mRNA model control group decreased and TLR4 mRNA increased. Compared with model control group, miR-146a mRNA in Ganlu Xiaodu Dan therapy group, incomplete Qing prescription therapy group and incomplete Li prescription therapy group all increased while TLR4 mRNA decreased, and differences between ribavirin control group and model control group were not significant. Compared with Ganlu Xiaodu Dan therapy group, both expressions of miR-146a and TLR4 mRNA in incomplete Qing prescription therapy group were lower; miR-146a increased and TLR4 mRNA decreased in incomplete Li prescription therapy group. Compared with incomplete Qing prescription therapy group, miR-146a mRNA in incomplete Li prescription therapy group increased, but expression of TLR4mRNA between them was not significant. Conclusion Ganlu Xiaodu Dan can regulate the immune reactions caused by infection of EV71 by increasing expression of miR-146a mRNA and reducing expression of TLR4 mRNA. There may be antagonism effect between incomplete Qing prescription and incomplete Li prescription.

Objective: To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Shaoxing City from 2006 to 2022, so as provide insights into improvements of the HFRS control strategy. Methods: Data pertaining to HFRS cases in Shaoxing City from 2006 to 2022 were captured from the Surveillance System of China Information System for Disease Control and Prevention. The temporal, population and regional distributions of HFRS were analyzed using the descriptive epidemiological method, and the trends in incidence of HFRS were evaluated using annual percent change (APC). Results: Totally 1 022 HFRS cases were reported in Shaoxing City from 2006 to 2022, with annual average incidence of 1.22/105 and three deaths. The incidence of HFRS appeared a tendency towards a decline in Shaoxing City from 2006 to 2022 (APC=-11.101%, t=-9.930, P<0.001), and the incidence of HFRS peaked from May to June and from November to January of the next year. A higher incidence of HFRS was seen in men than in women (1.76/105 vs. 0.68/105; χ2=201.361, P<0.001). There were 714 HFRS cases at ages of 30 to 59 years (69.86%), and farmers were the predominant occupation (78.18%). The three counties with the largest number of HFRS cases included Zhuji (366 cases), Xinchang (263 cases) and Shengzhou (134 cases). The incidence of HFRS was lower in urban districts (Yuecheng, Keqiao and Shangyu) than in counties (Zhuji, Shengzhou and Xinchang) (0.58/105 vs. 1.96/105; χ2=326.880, P<0.001). Conclusion The incidence of HFRS appeared a tendency towards a decline in Shaoxing City from 2006 to 2022, and the incidence was high in late spring, early summer and winter. The HFRS cases were mainly males, young and middle-aged people, and farmers, and predominantly distributed in counties. Targeted control measures are needed.

As the second largest vector of infectious diseases, ticks carry and transmit various pathogens that cause human infections and pose a serious public health hazard. In recent years, there has been an ongoing epidemic of tick-borne fever with thrombocytopenia syndrome virus (SFTSV), as well as the occurrence of human infections by brand-new viruses such as Jingmen tick virus (JMTV) and Alongshan virus (ALSV) in China. This paper will review the advancement of disease clinical characteristics, laboratory methods of virus isolation, immunology and molecular biology of these emerging tick-borne viral diseases in China.

Autoimmune diseases refer to clinical diseases caused by the body′s autoimmune tolerance state being broken or autoimmune cells being abnormally regulated, and the immune system produces autoantibodies, causing self-tissue damage or abnormal function. Most of the causes are unknown and easy to repeat, causing a huge burden on the quality of life of patients. Infectious pathogens have a potential role in initiating autoimmune processes and exacerbating disease progression, and conversely, some pathogens can suppress autoimmune responses. This paper summarizes the relationship between different types of infection and autoimmune diseases. Possible mechanisms of action include molecular mimicry of pathogen antigens, activation of bystander T or B cells, modification of autoantigens, and epitope diffusion.

Objective To explore the impact of diagnosis related groups (DRGs) payment and drug zero plus on the management of intensive care medicine department. Methods The clinical data of patients in one year from 2016 to 2017 admitted into the Department of ICU in Liuzhou Worker's Hospital concerning their numbers of discharged patients, transferred patients, bed utilization rate, number of bed turnover, average length of stay of discharged patients, cure and improvement rates, admission and discharge diagnostic coincidence rate, 3-day definite diagnosis rate, clinicopathological diagnosis coincidence rate, rescue success rate, total income, drug proportion, consumable proportion, DRGs payment and settlement data, etc were retrospectively analyzed to explore the dual challenges, DRGs payment and drug zero plus, facing the department and how to respond and deal with them. Results In 2016 and 2017, the total incomes of the department of critical care medicine in our hospital were 42.107 0 million yuan and 41.371 3 million yuan respectively, and the medical insurance incomes were 15.03 million yuan and 16.69 million yuan respectively;in 2016 and 2017, 2 693 patients and 2 922 patients were admitted and treated respectively; 595 patients and 577 patients were discharged respectively, with 2 071 patients and 2 334 patients transferred respectively; the balances of the department were 15.48 million yuan and 29.11 million yuan, respectively. From July to December 2017, the medical insurance DRGs payment data suggested that the proportion of loss of the department be 7.02%. Accelerating the Grade 6 electronic medical records and informationization construction, adopting the severe disease information solution program and fine quality control management in the department of critical care medicine can reduce the cost of manpower.

Objective:To exploring the uptake of fibroblast activation protein (FAP) inhibitor (FAPI) in pancreatic cancer through 68Ga-FAPI-04 PET/CT imaging, and provide a basis for the FAP-targeted imaging of pancreatic cancer. Methods:Pancreatic cancer-patient-derived tumor xenograft (PDX) mouse models ( n=8) were developed, then 68Ga-FAPI-04 and 18F-FDG microPET/CT imaging were performed (4 in each group). The differences of percentage activity of injection dose per gram of tissue (%ID/g) of 68Ga-FAPI-04 and 18F-FDG were analyzed by independent-sample t test. 68Ga-FAPI-04 and 18F-FDG PET/CT imaging were performed in 5 patients (4 males, 1 female, age: 46-74 (63.0±11.9) years) with pancreatic cancer, and the maximum standardized uptake value (SUV max) of 68Ga-FAPI-04 and 18F-FDG in primary pancreatic cancer and the SUV max ratio of liver metastases to liver tissue were compared by paired t test. Results:MicroPET/CT imaging showed that 68Ga-FAPI-04 was obviously uptaken at all time points in the tumor of PDX mice. The uptake of 68Ga-FAPI-04 in PDX mice 60 min after injection was significantly higher than that of 18F-FDG ((6.58±0.44) and (4.29±0.13) %ID/g; t=4.152, P=0.008 9). PET/CT showed that the SUV max of 68Ga-FAPI-04 in pancreatic cancer was significantly higher than that of 18F-FDG (16.82±3.08 and 5.14±2.20; t=6.893, P=0.000 1) and the SUV max ratio of liver metastases to liver tissue of 68Ga-FAPI-04 was also significantly higher than that of 18F-FDG (4.57±1.47 and 1.30±0.16; t=3.803, P=0.019 1). Conclusion:68Ga-FAPI-04 can be highly uptaken in pancreatic cancer, suggesting that FAP can be a potential target for PET/CT imaging of pancreatic cancer.
