Objective:To investigate the protective effects of an anti-inflammatory mixture on acute lung injury (ALI) induced by sepsis in rats, as well as its possible mechanisms.Methods:A total of 40 Sprague-Dawley (SD) rats were randomly divided into the sham group, septic ALI model group (model group), 3-methyladenine (3-MA) control group, and anti-inflammatory mixture pretreatment group, with 10 rats in each group. Cecal ligation and perforation (CLP) was performed to reproduce a septic ALI model. The rats in the sham group only underwent opening and closing the abdomen without perforation and ligation. Both groups were given saline gavage and intraperitoneal injection for 3 consecutive days before surgery. The 3-MA control group was given intraperitoneal injection of saline and autophagy inhibitor 3-MA 15 mg/kg for 3 consecutive days before modeling. The anti-inflammatory mixture pretreatment group was given 8.8 mL/kg of anti-inflammatory mixture by gavage [the composition of anti-inflammatory mixture: rhubarb 15 g (after the next), coptis chinensis 15 g, baical skullcap root 12 g, magnoliae cortex 12 g, dahurian patrinia herb 30 g] and saline intraperitoneal injection for 3 consecutive days before modeling. The rats in each group were anesthetized 24 hours after surgery and died due to abdominal aortic blood collection. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum inflammatory cytokines interleukins (IL-1β and IL-6). Lung tissue was taken and then the bronchoalveolar lavage fluid (BALF) was collected, and the levels of IL-1β and IL-6 were detected by ELISA. Lung wet/dry weight (W/D) ratio was measured. After hematoxylin-eosin (HE) staining, the histopathological changes of the lungs were observed under light microscopy. Western blotting was used to detect the expression of autophagy markers microtubule-associated protein 1 light chain 3-Ⅱ/Ⅰ (LC3-Ⅱ/Ⅰ) and Beclin-1 protein in lung tissue. Autophagosomes in lung tissue were observed with transmission electron microscopy.Results:Compared with the sham group, the rats in the model group exhibited severe destruction of lung tissue structure, with significant infiltration of inflammatory cells, the lung W/D ratio and the levels of IL-1β and IL-6 in serum and BALF were significantly increased, the expressions of LC3-Ⅱ/Ⅰ and Beclin-1 protein were down-regulated, the autophagosomes were more. The rats in the 3-MA control group exhibited more severe lung tissue injury as compared with the model group, the lung W/D ratio and the levels of inflammatory cytokines in serum and BALF were further increased, the expressions of LC3-Ⅱ/Ⅰ and Beclin-1 protein still showed a decrease tendency as compared with the sham group, and the autophagosomes were less than that in the model group. Compared with the model group, the anti-inflammatory mixture pretreatment group showed milder lung tissue injury with a minimal amount of inflammatory cell infiltration, the lung W/D ratio was significantly reduced (7.07±1.02 vs. 11.33±1.85, P < 0.05), the levels of IL-1β and IL-6 in both serum and BALF were significantly decreased [IL-1β (ng/L): 26.04±3.86 vs. 40.83±5.46 in serum, 17.75±2.02 vs. 26.86±4.32 in BALF; IL-6 (ng/L): 91.28±10.15 vs. 129.44±13.05 in serum, 76.06±7.51 vs. 120.91±7.47 in BALF, all P < 0.05], and the ratio of LC3-Ⅱ/Ⅰ and Beclin-1 protein expression were significantly increased [LC3-Ⅱ/Ⅰ ratio: 1.23±0.02 vs. 0.60±0.02, Beclin-1 protein (Beclin-1/GAPDH): 2.37±0.33 vs. 0.62±0.05, both P < 0.05]. Furthermore, an increase in the number of autophagosomes was observed. Conclusion:The anti-inflammatory mixture improves lung injury in rats with sepsis induced by CLP and reduce inflammation levels, potentially through upregulation of Beclin-1-mediated autophagy.

Objective To investigate the value of peripheral blood soluble interleukin-2 receptor(sIL-2R),CD4+lymphocyte percentage/CD8+lymphocyte percentage ratio(hereinafter referred to as CD4+/CD8+)and tumor necrosis factor-α(TNF-α)in evaluating the efficacy of chemotherapy in elderly patients with newly treated active pulmonary tuberculosis.Methods A total of 102 elderly patients with newly treated active tu-berculosis admitted to the hospital from December 2019 to December 2022 were enrolled in the study as the observation group,and 102 healthy people aged 60 and older who underwent physical examination in the hos-pital during the same period were enrolled as the control group.The levels of sIL-2R,TNF-α and CD4+/CD8+in peripheral blood were compared between the two groups,and the correlations between sIL-2R,TNF-α and CD4+/CD8+were analyzed.The observation group was treated with 2HRZE/4HR anti-tuberculosis treatment regimen.The levels of sIL-2R,TNF-α and CD4+/CD8+in peripheral blood of patients with different efficacy before treatment,1 month and 6 months after treatment in the observation group were compared.The correla-tion between sIL-2R,CD4+/CD8+,TNF-α levels and therapeutic effect was analyzed.The receiver operating characteristic(ROC)curve was used to analyze the efficacy of indicators in evaluating the efficacy of chemo-therapy in elderly patients.Results The levels of sIL-2R and TNF-α in the observation group were higher than those in the control group,while CD4+/CD8+was lower than that in the control group,and the differ-ences were statistically significant(P＜0.05).In the observation group,sIL-2R and TNF-α were negatively correlated with CD4+/CD8+(P＜0.05),sIL-2R was positively correlated with TNF-α(P＜0.05).After 1 month and 6 months of treatment,the levels of sIL-2R and TNF-α in patients with apparent efficacy were low-er than those in patients with efficacy,and the latter were lower than those in patients with no effect,while the CD4+/CD8+in patients with apparent efficacy was higher than that in patients with efficacy,and the latter was higher than that in patients with no efficacy,and the differences were statistically significant(P＜0.05).The levels of sIL-2R and TNF-α were negatively correlated with the efficacy(P＜0.05),and CD4+/CD8+was positively correlated with the efficacy(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of sIL-2R,CD4+/CD8+,and TNF-α used in combination to assess efficacy was significantly greater than the AUCs of the single indicators used in the assessment at each time point of treatment(P＜0.05),and the AUC of the combination of the indicators was greater after 6 months of treatment than after 1 month of treatment(P＜0.05).Conclusion The levels of sIL-2R,CD4+/CD8+and TNF-α are closely related to the ef-ficacy of chemotherapy in elderly patients with newly treated active pulmonary tuberculosis,and the combina-tion of the above indicators has certain reference value in evaluating the efficacy of chemotherapy in patients.

Objective: To analyze the clinical characteristics and prognosis of primary and secondary pancreatic diffuse large B-cell lymphoma (DLBCL) . Methods: Clinical data of patients with pancreatic DLBCL admitted at Shanghai Rui Jin Hospital affiliated with Shanghai Jiao Tong University School of Medicine from April 2003 to June 2020 were analyzed. Gene mutation profiles were evaluated by targeted sequencing (55 lymphoma-related genes). Univariate and multivariate Cox regression models were used to evaluate the prognostic factors of overall survival (OS) and progression-free survival (PFS) . Results: Overall, 80 patients were included; 12 patients had primary pancreatic DLBCL (PPDLBCL), and 68 patients had secondary pancreatic DLBCL (SPDLBCL). Compared with those with PPDLBCL, patients with SPDLBCL had a higher number of affected extranodal sites (P<0.001) and had higher IPI scores (P=0.013). There was no significant difference in the OS (P=0.120) and PFS (P=0.067) between the two groups. Multivariate analysis indicated that IPI intermediate-high/high risk (P=0.025) and double expressor (DE) (P=0.017) were independent adverse prognostic factors of OS in patients with pancreatic DLBCL. IPI intermediate-high/high risk (P=0.021) was an independent adverse prognostic factor of PFS in patients with pancreatic DLBCL. Targeted sequencing of 29 patients showed that the mutation frequency of PIM1, SGK1, BTG2, FAS, MYC, and MYD88 in patients with pancreatic DLBCL were all >20%. PIM1 (P=0.006 for OS, P=0.032 for PFS) and MYD88 (P=0.001 for OS, P=0.017 for PFS) mutations were associated with poor OS and PFS in patients with SPDLBCL. Conclusion: There was no significant difference in the OS and PFS between patients with PPDLBCL and those with SPDLBCL. IPI intermediate-high/high risk and DE were adverse prognostic factors of pancreatic DLBCL. PIM1, SGK1, BTG2, FAS, MYC, and MYD88 were common mutations in pancreatic DLBCL. PIM1 and MYD88 mutations indicated worse prognosis.

Objective:To learn about the knowledge, attitude and behavior of brucellosis and brucellosis infection in Tongyu County, Jilin Province, and to provide a reference for the formulation of prevention and control measures in relocated poverty alleviation and relocation areas.Methods:Using a multi-stage sampling method, three townships, Xianghai Township, Wulanhua Town and Xinhua Town were selected in Tongyu County, where the incidence of brucellosis is high in Jilin Province; then Miren, Huimin, Longjing, Xinfeng and Dayou villages from the three townships were surveyed. A face-to-face questionnaire survey was conducted among the villagers to collect the knowledge, attitude and behavior of brucellosis; and blood samples were collected from the villagers according to the principle of informed consent for brucellosis serological tests, and according to the "Diagnostic criteria for Brucellosis (WS 269-2007)" for diagnosis.Results:A total of 274 questionnaires were distributed and 244 valid questionnaires were collected with a recovery rate of 89.05%. Among them, 233 people had heard of brucellosis, accounting for 95.49%. The total awareness rate of knowledge related to brucellosis prevention and control was 39.29% (2 205/5 612), of which the total awareness rate of "knowledge related to brucellosis prevention" was 71.99% (527/732), and the total awareness rate of "knowledge related to human infection with brucellosis" was 38.08% (1 115/2 928), and the total awareness rate of "knowledge about brucellosis in animals" was 28.84% (563/1 952). A total of 90.13% (21/233) people supported the brucellosis prevention and control plan (such as free screening for brucellosis, publicity and education, immunization, culling, etc.), and 61.54% (48/78) of the people would take the initiative to buy protective equipment. The contact rates of livestock through assisted feeding and slaughtering were 27.46% (67/244) and 11.48% (28/244), respectively, and the total protection rates of sheep pens cleaning and slaughtering were 30.91% (102/330) and 21.43% (30/140), respectively. In terms of brucellosis infection, a total of 1 confirmed case, 1 latent infection and 37 suspected cases were found.Conclusions:The awareness rate of "knowledge related to brucellosis prevention" in Tongyu County is generally good, but the awareness rate of "knowledge about brucellosis in animals" is low, and the protection rate of some brucellosis prevention and control behaviors is poor. Health and epidemic prevention departments should carry out targeted health education, improve and optimize propaganda methods in order to improve the protection level of the general population and reduce the risk of brucellosis infection.

ObjectiveTo study the effect of Huazhuo Jiedu Huoxue Tongluo （HJHT） prescription on the intestinal flora in rats with cerebral ischemia-reperfusion injury， and to explore the mechanism of Chinese medicinal prescription regulating intestinal flora to restore the balance of brain-gut axis. MethodFifty male SPF SD rats were randomly assigned into sham group， model group， high-dose HJHT group （25.0 g·kg^-1）， medium-dose HJHT group （12.5 g·kg^-1）， and low-dose HJHT group （6.25 g·kg^-1）， with 10 rats in each group. The rat model of permanent middle cerebral artery infarction was established according to Longa method and previous research experience， and reperfusion was performed 2 h after ischemia. The recovery of neurological function deficit and the percentage of cerebral infarction area were detected 72 h after administration. Real-time PCR was performed to detect the mRNA levels of Occludin and zonula occludens-1 （ZO-1） in rat colon. Hematoxylin-eosin （HE） staining was conducted to reveal the intestinal damage. The feces of 6 rats in each group were collected for 16S rRNA sequencing. The expression of Treg and Th17 in intestinal tissue， peripheral blood， and brain tissue were detected. ResultCompared with the sham group， the model group showed obvious neurological deficit （P<0.05） and large cerebral infarction area （P<0.05）. High-dose and medium-doses HJHT alleviated the symptoms of neurological impairment （P<0.05） and reduce the cerebral infarction area （P<0.05） compared with the model group. Compared with the sham group， the model group showed destroyed structure of colonic mucosa and incomplete epithelial cells and goblet cells， while high-dose and medium-doses HJHT alleviated such changes. The mRNA levels of Occludin and ZO-1 in the model group were lower than those in the sham group （P<0.05），and the high-dose HJHT groups were higher than the model group （P<0.05）. The intestinal flora structure was significantly different between the model group and the sham group while similar between the high-dose HJHT group and sham group. Compared with the sham group， the model group showed down-regulated expression of Treg and up-regulated expression of Th17 in the intestinal tissue， peripheral blood， and brain tissue， and high-dose and medium-dose HJHT alleviated the changes in the expression of Treg and Th17 in the model group （P<0.05）. ConclusionHuazhuo Jiedu Huoxue Tongluo prescription may improve the permeability of intestinal wall by adjusting the abundance and diversity of intestinal microorganisms to reduce the migration of intestinal Th17 cells toward the ischemic lateral brain tissue， mitigate the inflammatory response， and thus alleviate the cerebral ischemia-reperfusion injury in rats.
