Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Background Sleep quality is one of the important factors affecting soldiers’ task performance. Objective To explore the effects of mindful attention awareness, burnout, and occupational stress on sleep quality among soldiers in plateau areas. Methods A total of 1090 soldiers were selected from four units in plateau areas by cluster sampling method and were asked to participate a cross-sectional questionnaire survey using the Pittsburgh Sleep Quality Index (PQSI), Occupational Stress Inventory (OSI), Maslach Burnout Inventory-General Survey (MBI-GS), and Mindful Attention Awareness Scale (MAAS). Correlation analysis, regression analysis, and mediated effect test were conducted for the study. Results Of the 1090 soldiers recruited, 1082 soldiers returned valid questionnaires, and the valid recovery rate was 99.26%. The median (P₂₅, P₇₅) score of PSQI was 4.00 (2.00,7.00), the median score of OSI was 26.00 (17.00, 34.00), the median score of MBI-GS was 3.53 (3.13, 4.00), and the median score of MAAS was 71.00 (59.00, 82.00). The burnout and mindful attention awareness levels varied among military personnel of different age groups (P<0.05), so did the burnout and occupational stress levels among military personnel of different length of service groups (P<0.05), and the occupational stress, PSQI, burnout, and mindful attention awareness levels among military personnel with different educational backgrounds and genders (P<0.05). The results of mediated effect test showed that occupational stress and burnout had both a parallel mediated effect and a sequential mediating effect on the relationship between mindful attention awareness and sleep quality, with effect sizes of 15.3%, 21.5% and 31.8%, respectively. Conclusion There is a mediated effect on the relationship between mindful attention awareness and sleep quality by the occupational stress and burnout of military personnel in plateau areas, and sleep quality is also affected by mindful attention awareness through the chain-mediated effect of occupational stress and burnout.

Echinococcosis is a common zoonotic disease in livestock; the type with the highest incidence is cystic echinococcosis (CE). In clinical management, patients with CE of the liver in which the cyst wall is calcified have been found to have better prognoses than those without calcification. In this study, we collected calcified and uncalcified cyst wall tissue from patients with hepatic CE and observed significant changes in the expression of 2336 messenger ribonucleic acids (mRNAs), 178 long noncoding RNAs (lncRNAs), 210 microRNAs (miRNAs), and 33 circular RNAs (circRNAs) using high-throughput sequencing (HTS). Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of differentially expressed RNAs (DERNAs: DEmRNAs, DElncRNAs, DEmiRNAs, and DEcircRNAs) were performed to explore these RNAs’ potential biological functions and signaling pathways. Ultimately, the results of hematoxylin and eosin (H&E) and terminal deoxynucleotidyl transferase deoxyuridine triphosphate (dUTP) nick end labeling (TUNEL) staining confirmed the correlation between calcification and apoptosis of the cyst wall. In summary, this study was an initial exploration of the molecular-biological mechanism underlying spontaneous calcification of the hydatid cyst wall, and it provides a theoretical basis for exploring new targets for drug treatment in CE.

Objective: To evaluate the effectiveness for the construction of "mosquito-free village" in Xuejia Village, Pujiang County, Zhejiang Province, so as to provide the guidance for the construction of "mosquito-free village" in other rural areas. Methods: Density of adult mosquitoes in Xuejia Village was investigated using light trap method and density of larval mosquitoes was investigated using larval straw method from April to November each year. Totally 30 households of villagers were randomly selected, and their awareness rates of mosquito control knowledge, mosquito control behavior forming rates and satisfaction rates were surveyed through questionnaires. Investment during construction (from August 2016 to December 2018) and maintenance period (from 2019 to 2023) of "mosquito-free village" were investigated through data review and interviews. Long-term effects of "mosquito-free village" construction in Xuejia Village were evaluated in terms of mosquito density from 2016 to 2023, effectiveness of health education for villagers, satisfaction and investment. Results: Compared with the year 2016, the densities of adult and larval mosquitoes in Xuejia Village were significantly decreased from 2017 to 2023. The average monthly density of adult mosquitoes in 2023 decreased by 98.34%, and the average monthly 100 household index of larval mosquitoes decreased by 98.45% compared to 2016. The average monthly density of adult mosquitoes from 2019 to 2023 was less than or equal to one mosquito per light trap in a night, and the average monthly 100 household index of larval mosquitoes was less than or equal to five places per 100 households. The awareness rate of mosquito control knowledge was 93.33%, the behavior forming rate was 86.67%, and the satisfaction rate was 90.00%. By December 2023, the total investment during construction and maintenance period was 450 thousand Yuan, with an average annual investment of 60.7 thousand Yuan and average annual investment of 206.61 Yuan per household. The average annual investment during maintenance period was 36.2 thousand Yuan, and the average annual investment per household was 109.70 Yuan. Conclusion The mosquito density, effectiveness of health education for villagers and satisfaction of "mosquito-free village" in Xuejia Village all meet the evaluation criteria of "mosquito-free village", and the investment is reasonable, making it suitable for promotion to other rural areas.

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Objective:To investigate the biological effects of acute high-dose radon exposure on mice.Methods:BALB/c male mice aged 6 to 8 weeks were exposed once in an HD-3 ecological radon chamber with an average radon concentration of 7 × 10 5 Bq/m 3 for 10 h. Mice were weighed, their lung tissues and blood samples were collected at 1, 2 and 3 months after exposure. Control groups were set up at the three time points with four mice in each group. For these mice, the lung tissue pathology was observed using hematoxylin-eosin (HE) staining method, routine blood tests were conducted using a hematology analyzer and the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in the serum and lung tissues were measured using corresponding assay kits. Results:The HE staining result revealed that compared to the control groups, the experimental groups exhibited thickening of alveolar walls and increased infiltration of granulocyte, whose degrees, however, reduced over time and displayed no significant difference at 3 months after exposure. There was no significant difference in body weight or blood routine between the experimental and control groups. The detection result revealed decreased SOD levels in the lung tissues at 2 months after exposure, which were (11.34 ± 1.03) U/mgprot and (9.75 ± 0.71) U/mgprot, respectively for the control and experimental groups ( t = 2.54, P < 0.05). The MDA levels in lung tissue increased at 1 month after exposure, which were(2.30 ± 0.24) and (2.77 ± 0.29) nmol/mgprot, respectively for the control and experimental groups ( t = 2.49, P < 0.05). At 3 months after exposure, the SOD and MDA levels differed insignificantly between the control and experimental groups ( P > 0.05). Conclusions:After acute high-dose radon exposure, the mice suffered damage to the lung tissue, with changes in their oxidative stress indicators being detected. However, these effects gradually diminished at 3 months after exposure. Additionally, acute high-dose radon exposure did not give rise to significant changes in the body weight or routine blood result of the mice.

Objective:The epidemiological and host animal pathogen data of leptospirosis in the population of Zhejiang Province in 2023 were analyzed, providing scientific basis for formulating prevention and control strategies of leptospirosis.Methods:The data of human leptospirosis in the population were collected from the China Information System for Disease Control and Prevention, and analyzed using descriptive epidemiological methods. The data on isolation, culture, and nucleic acid testing of Leptospira pathogens from mouse kidneys, frog kidneys, pig kidneys, and duck kidneys as well as duck serum antibody data were collected from Zhejiang Provincial Center for Disease Control and Prevention "Leptospirosis Surveillance Project of Zhejiang Province". The carrying and changing status of Leptospira epidemic microbiota in populations and host animals were analyzed. Results:In 2023, a total of 83 cases of leptospirosis were reported in Zhejiang Province, with a incidence rate of 0.126 2/ 100 000, aged (62.66 ± 11.31) years, including 68 males and 15 females. Leptospirosis cases were reported in 11 cities, mainly concentrated in the southern cities of Wenzhou City, Lishui City and Taizhou City(a total of 68 cases), accounting for 81.93% of the total number of cases. August to October were high incidence months for leptospirosis (a total of 70 cases), accounting for 84.34% of the total number cases. The male to female ratio of patients was 4.53 ∶ 1.00, and all were adults ≥20 years old, the middle and old people aged 45 - 79 years were the high-risk population (a total of 77 cases), accounting for 92.77% of the total number of cases. The patient's occupation was mainly farmers, with a total of 54 cases, accounting for 65.06% of the total number cases. The shortest time from onset to initial diagnosis for patients with leptospirosis was 0 day, and the longest was 13 days. The shortest time from initial diagnosis to confirmed diagnosis was 0 day, and the longest was 16 days. The 72.29% of the leptospirosis cases (60 cases) had a history of field labor or suspected contact with contaminated water within one month before the onset of the disease, and 18.07% of the leptospirosis cases (15 cases) had a history of contact with animals such as mice, frogs, pigs, cows, dogs, fish or ducks, or their excreta within one month before the onset of the disease. The average nucleic acid positive rate of host animals with leptospirosis was 5.92% (31/524) in mouse kidney, 6.74% (36/534) in frog kidney, and 0.66% (1/151) in pig kidney. The isolation and culture of leptospirosis from duck kidney, nucleic acid detection, and antibody detection in duck blood were all negative. The leptospirosis bacteria detected in human population were serogroup Icterohaemorrhagiae (3 samples) and Hebdomadis (4 samples), and the bacteria group detected in host animals was serogroup Icterohaemorrhagiae (3 samples). Conclusions:The outbreak of leptospirosis in Zhejiang Province mainly occurs in the summer and autumn, with the affected areas mainly concentrated in the southern region of Zhejiang Province. The affected population is mainly middle-aged and elderly males, and the population carrying Leptospira is still mainly composed of the serogroup Icterohaemorrhagiae and the Hebdomadis, with the host animal being the serogroup Icterohaemorrhagiae.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.
