Objective To investigate the effect of sufentanil(suf)on hepatic injury in burn sepsis rats by regulating Janus kinase 2(JAK2)/signal transduction and transcriptional activator 3(STAT3)signaling pathway.Methods SD rats were randomly divided into the control group,the model group,the suf low-dose group(0.75 μg/kg),the suf high-dose group(3 μg/kg),the imipenem group(90 mg/kg)and the suf high-dose+kumamycin group(3 μg/kg suf+4 mg/kg kumamycin).Serum liver function indexes including alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were detected.The pathological changes of liver tissue were observed by HE staining.The contents of tumor necrosis factor-α(TNF-α),monocyte chemoattractant protein-1(MCP-1)and interleukin(IL)-6 were detected by enzyme-linked immunosorbent assay(ELISA).Terminal deoxynucleotide transferase mediated dUTP nick end labeling(TUNEL)staining was used to detect hepatocyte apoptosis.Western blot assay was used to detect the expression of p-JAK2 and p-STAT3 proteins in liver tissue.Results Compared with the control group,the model group showed elevated serum levels of ALT and AST,swelling of liver cells and infiltration of numerous inflammatory cells in liver tissue.The levels of TNF-α,MCP-1 and IL-6 in liver tissue,apoptosis rate of liver cells,and expression levels of p-JAK2 and p-STAT3 proteins were increased(P＜0.05).Compared with the model group,serum levels of ALT and AST were reduced in the suf low-dose group and the suf high-dose group,and pathological damages of liver tissue were improved.The contents of TNF-α,MCP-1 and IL-6 in liver tissue,the apoptosis rate of liver cells,and the expression levels of p-JAK2 and p-STAT3 proteins were reduced(P＜0.05).Moreover,changes in above indicators were significantly higher in the suf high dose group of suf than those in the suf low dose group(P＜0.05),and there was no significant difference compared with the imipenem group.Kumamycin inhibited the improvement effect of high-dose suf on liver injury in rats with burn sepsis(P＞0.05).Conclusion Sufentanil may improve liver injury in burn-induced sepsis rats by inhibiting the JAK2/STAT3 signaling pathway.

Objective:To understand the common viral infection among the surveillance cases of fever respiratory syndrome (FRS) in nine provinces in China.Methods:The research data were obtained from nine provinces (Anhui, Beijing, Guangdong, Hebei, Hunan, Jilin, Shandong, Shaanxi and Xinjiang) in the "Infectious Disease Surveillance Technology Platform Information Management System" of the Chinese Center for Disease Control and Prevention from January 2009 to June 2021. Finally, 8 243 FRS cases with nucleic acid detection results of eight viruses [human influenza virus (HIFV), human respiratory syncytial virus (HRSV), human adenovirus (HAdV), human parainfluenza virus (HPIV), human rhinovirus (HRV), human metapneumovirus (HMPV), human coronavirus (HCoV) and human Boca virus (HBoV)] were included in the study. The χ 2 test/Fisher exact probability method was used to analyze the difference of virus detection rate in different age groups, regions and seasons. Results The M ( Q1, Q3) age of 8 243 FRS cases was 4 (1, 18) years old, and 56.56% (4 662 cases) were children under 5 years old. Males accounted for 58.1% (4 792 cases) of all cases. All cases were from outpatient/emergency department (2 043 cases) and inpatient department (6 200 cases). The virus detection rates of FRS cases from high to low were HRSV, HIFV, HPIV, HRV, HAdV, HMPV, HCoV and HBoV. Two or more viruses were detected simultaneously in 524 cases, accounting for 15.66% of virus-positive cases. The difference of the virus detection rate in different age groups was statistically significant (all P values<0.05), and the virus detection rate in children<5 years old was higher (49.96%). The positive rate of any virus in south China was higher than that in north China ( P<0.001). The virus-positive FRS cases were detected throughout the year. The detection rate of HRSV was higher in autumn and winter. The detection rate of HIFV was higher in winter. The detection rate of HMPV was higher in winter and spring. The detection rates of HPIV, HRV, HCoV and HBoV were higher in summer and autumn, while there was no significant difference in the detection rate of HAdV in different seasons. Compared with 2009-2019, the detection rate of any virus in 2020-2021 decreased from 41.37% to 37.86%. The detection rate of HIFV decreased sharply from 10.62% to 1.37%. The detection rate of HPIV decreased from 8.24% to 5.88%. The detection rate of HRV and HBoV increased from 5.43% and 1.79% to 9.67% and 3.19%, respectively. Conclusion:HRSV and HIFV infections are more common among FRS cases in nine provinces in China from 2009 to 2021, and the epidemiological characteristics of eight common respiratory viruses vary in different age groups, regions and seasons.

Objective:To clarify the infection and epidemic characteristics of the human metapneumovirus (HMPV) in Chinese patients with febrile respiratory syndrome (FRS), and to provide important baseline data for clinical diagnosis, treatment, prevention and control of HMPV-induced respiratory tract diseases in China.Methods:FRS cases from January 2009 to June 2021 in 9 provinces in China, including Beijing, Hebei, Jilin, Shandong, Shaanxi, Xinjiang, Anhui, Guangdong, Hunan were retrospectively analyzed for their respiratory samples, clinical and epidemic data.The respiratory samples were detected for HMPV by quantitative real-time PCR.Results:A total of 11 660 cases were tested for HMPV, involving 296 (2.54%) HMPV-positive cases.Among 296 HMPV-positive cases, 218 were single HMPV infection, and 78/296 (26.35%) were co-infected with one or more respiratory viruses.HMPV mainly affected children under 5 years of age (3.10%), and in this population, the proportion of pneumonia in HMPV co-infection cases was significantly higher than that of single HMPV infection.HMPV could be detected all year round, which was more popular in winter and spring, with the peak of HMPV epidemic in March.Conclusions:HMPV is one of the important pathogens causing acute respiratory infection in children, showing a clear seasonal epidemic.HMPV can be infected alone or in combination with other respiratory viruses, which may increase the risk of pneumonia in children.

Objective:To evaluate the safety and efficacy of metal clips combined with endoscopic histoacryl injection for gastric varices with spontaneous portosystemic shunts.Methods:The clinical data and complications of 32 patients who were treated with metal clips combined with endoscopic histoacryl injection at Beijing Ditan Hospital of Capital Medical University from May 2016 to October 2018 were collected and analyzed.Results:Hemostasis was achieved in all patients, and the median volume of histoacryl was 3.8 mL. Varices were eradicated or disappeared in 9 cases, and the degree of varices were lessened in 23 cases. No rebleeding was found at 72 h, 7 d, 14 d and 6 weeks after operation in any patient. No ectopic embolism occurred.Conclusion:Metal clips combined with endoscopic histoacryl injection is effective and safe to treat gastric varices with spontaneous portosystemic shunts.

Objective To introduce and evaluate the methods of ultrasound-guided compression repair (UGCR) or ultrasound-guided compression-puncture hematocele repair (UGCPHR) in treatment of post-catheterization femoral arterial pseudoaneurysms. Methods Two patients with femoral arterial pseudoaneurysms (3.0 cm?3.0 cm) were treated with UGCPHR, a 18-gauge blunt needle self-retrained with a syringe was placed into the pseudoaneurysm flow lumen along the primary cleft, to compress this site to cut-out continuously the blood flow into the lumen, then to draw all the hemocele out with the syringe, to slowly decompress after continuing the compression for 20-30 minutes, and to repeat this procedure if blood flow signals still existed. Results All the five cases were treated successfully, without large hardening nodules. Four cases were treated successfully at one time, one case was successfully with UGCPHR after failure with UGCR. Conclusion For the treatment of post-catherization femoral arterial pseudoaneurysms, UGCR or UGCPHR depending on the size of pseudoaneurysms is effective, safe and technically simple, without local largely hardening nodules formation in post-repair or any effects on interventional diagnosis and treatment in short periods along the same passway.
