Objective:To analyze the drug-resistance pattern and molecular epidemiological characteristics of Enterobacteriales carrying the blaNDM gene in Lishui, aiming to guide clinical anti-infection treatment. Methods:Non-duplicate blaNDM-carrying Enterobacteriales, isolated from Lishui Central Hospital, were collected and identified by VITEK MS. The minimal inhibitory concentrations (MICs) were detected by the broth microdilution method. The ST types of the strains were determined by multilocus sequence typing (MLST). Plasmid types were identified by transformation or conjugation experiments and replication initiator amplification experiments. The transposon structures were detected by PCR amplification. Finally, the epidemic regularity of blaNDM gene in Lishui was analyzed from three levels: clonal group, plasmid, and mobile genetic elements. Results:A total of 109 blaNDM-positive strains were collected. Among them, 60 strains carried the blaNDM-1 gene and 49 strains carried the blaNDM-5 gene. The 109 strains showed 100% resistance to ceftazidime and cefotaxime. The resistance rates to peracillin-tazobactam and imipenem were higher than 80%. Strains carrying the blaNDM-5 gene were more resistant to meropenem than those carrying blaNDM-1 gene( P<0.05). A total of 68 STs were detected from 109 strains, and IncX3, IncFⅡγ, IncA/C and IncT/R plasmids were detected, and 90.83% of the blaNDM genes were located in the IncX3 plasmid. Twelve types of blaNDM gene surrounding structures existed, and they all carried the highly conserved blaNDM- bleMBL- trpF gene sequence. Conclusions:The blaNDM gene has diverse transmission modes in Lishui. The IncX3 plasmid is the main factor mediating its transfer, and all strains carry highly conserved blaNDM- bleMBL- trpF gene sequence.

Objective To investigate the intervention effects of Yangqing Chenfei Fang (YCF), Baojin Chenfei Fang (BCF), and Jinshui Chenfei Fang (JCF) at different pathological stages of silicosis in a rat model. Methods A total of 216 specific pathogen free rats were randomly divided into control group, silicosis group, tetrandrine group, YCF group, BCF group and JCF group, with 35-36 rats in each group (11-12 rats at each time point). The rats in control group were treated with intragastric administration of pure water [administration volume at 2.5 mL/(kg·time)], while the rats of other five groups were treated with silica suspension at 250 mg/kg body weight to induce a silicosis model using the one-time non-exposed tracheal method. Intragastric administration of the corresponding drugs was performed at three time points at days 1-14 (early stage of silicosis), days 15-28 (middle stage of silicosis), and days 29-42 (late stage of silicosis) after modeling. Pulmonary function enhanced pause (Penh), forced vital capacity (FVC), and dynamic lung compliance (Cdyn) of rats in the six groups was assessed on days 15, 29, and 43 after modeling. Histopathological changes in lung tissues were observed, and relative expression levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β, hydroxyproline, collagenⅠ(COL-Ⅰ), and α-smooth muscle actin (α-SMA) were detected in lung tissues. Results i) Pulmonary function index. The index of Penh in three stages of silicosis of rats in YCF group, BCF group and JCF group was lower than that in the silicosis group at the same stage (all P<0.05), and the index of Penh was higher than that in the tetrandrine group at the same stage (all P<0.05). The index of FVC of rats in YCF group, BCF group and JCF group at the middle stage was higher than that in the silicosis group at the same stage (all P<0.05), as well as the index of Cdyn was higher than that in the tetrandrine group at the same stage (all P<0.05). ii) Histopathology of lung tissue. Rats of the silicosis group exhibited alveolitis, fibro stripe, and collagen deposition in lung tissues in the early stage compared with rat of the control group, with fibrosis progressively worsening over time and inflammation persisting throughout the disease course. Pathological changes of lung tissues were alleviated to varying degrees in the tetrandrine groups, YCF group, BCF group and JCF group compared with that of the silicosis group. Compared with the same stage of silicosis group, the Ashcroft scores of lung tissues in the YCF group and BCF group were lower in the middle and late stages (all P<0.05). The Ashcroft score of lung tissues in the BCF group in the middle and late stages was lower than that in tetrandrine group at the same stage (all P<0.05), while the Ashcroft score in the middle stages was lower than that in YCF group at the same stage (P<0.05). The Ashcroft score of lung tissue in the JCF group was lower than that in the silicosis group, tetrandrine group and YCF group at all three stages (all P<0.05), and was lower than that in BCF group at the early and late stage of silicosis (all P<0.05). iii) Inflammatory factors. IL-6 level in the lung tissues in the YCF group, BCF group and JCF group decreased compared with that in the silicosis group at the same stage (all P<0.05), while IL-1β and TNF-α levels decreased at the early and middle stages (all P<0.05), hydroxyproline level decreased at all three stages (all P<0.05). iv) Collagen. The relatively expression of COL-Ⅰ in the lung tissues in the YCF group decreased at the late stage of silicosis compared with that in the silicosis group at the same stage (all P<0.05), while the relatively expression of α-SMA decreased at the middle and late stages (all P<0.05). Compared with the same stage of silicosis group, the relative expression of COL-Ⅰ and α-SMA of the lung tissues reduced in the BCF group and JCF group at all stages (all P<0.05). The relative expression of COL-Ⅰ of the lung tissues reduced in the BCF group at the late stage compared with that in the YCF group in the same stage (all P<0.05), while the relative expression of α-SMA decreased at the early and middle stages (all P<0.05). The relative expression of COL-Ⅰ of the lung tissues reduced in the JCF group at late stage of silicosis (all P<0.05), while the relative expression of α-SMA decreased at all three stages (all P<0.05), compared with the same stage of YCF group. Conclusion All three formulations of Chinese herbs are effective in improving lung function and alleviating the progress of lung inflammation and fibrosis. YCF is the most effective in suppressing inflammation in the early stage of silicosis. BCF excels in delaying fibrosis in the early and middle stages. JCF is the most effective in improving lung function and delaying fibrosis progression in the late stage.

Complete healing of the intestinal mucosa is considered as the ultimate goal of the treatment of inflammatory bowel disease (IBD). In the process of intestinal mucosal repair, growth factors play a key role in promoting mucosal inflammatory repair and initiating tissue regeneration. Platelet-rich plasma (PRP) is rich in hundreds of biologically active proteins and growth factors, which not only contain factors needed for mucosal healing but also provide inflammatory suppressors. This article reviews the application of PRP in mucosal healing of IBD and analyzes the related mechanism.

Objective To explore the effects and mechanism of Baitouweng Decoction in intestinal mucosal healing in mice with ulcerative colitis(UC)based on RIPK1/RIPK3/MLKL signaling pathway.Methods Totally 30 C57BL/6 male mice were randomly divided into control group,model group,Baitouweng Decoction group,infliximab group and combination group(Baitouweng Decoction+infliximab),with 6 mice in each group.A mouse model of UC was established by free administration of 3.5%sodium gluconate sulfate solution for 7 days.After modeling,Baitouweng Decoction group was given 8 g/kg Baitouweng Decoction solution by gavage daily,while the infliximab group was given 5 mg/kg infliximab intraperitoneal injection,the combination group was given synchronous gastric and intraperitoneal injection,while the control group and model group were given equal volume of normal saline by gavage for 7 consecutive days.The body mass of mice was recorded daily,fecal characteristics were observed,and disease activity index(DAI)score was performed,colon length was measured after intervention,ELISA was used to detect the contents of serum interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α),RT-qPCR was used to detect mRNA expressions of RIPK1,RIPK3 and MLKL in colon tissue,Western blot and immunofluorescence staining were used to detect the expressions of RIPK1,RIPK3 and MLKL protein in colon tissue.Results Compared with the control group,the model group mice showed a decrease in body mass(P<0.01),an increase in DAI score(P<0.01),a shortened colon length(P<0.01),and an increase in serum IL-6 and TNF-α content(P<0.01);colonic mucosal was destructed,with disappearance of crypts and glandular structures,extensive infiltration of inflammatory cells,and increased pathological score of colon tissue(P<0.01);the mRNA and protein expressions of RIPK1,RIPK3 and MLKL in colon tissue increased(P<0.01,P<0.05).Compared with the model group,the body mass of mice in each treatment group increased(P<0.01),and the DAI score decreased(P<0.01),colon length increased(P<0.01),and the contents of serum IL-6 and TNF-α decreased(P<0.05,P<0.01);the destruction of the colonic mucosal barrier was reduced,the pathological score of colon tissue was reduced(P<0.05);the expressions of RIPK1,RIPK3 and MLKL mRNA and protein in colon tissue decreased(P<0.05,P<0.01).Conclusion Baitouweng Decoction can alleviate intestinal mucosal damage and inflammation in UC mice,and its mechanism may be related to the inhibition of the RIPK1/RIPK3/MLKL signaling pathway.

【Objective】 To study the safety, effectiveness and nursing of blood/fluid warmer during the process of plateletpheresis in winter. 【Methods】 The blood re-transfusion speed during plateletpheresis in winter and the time of blood passing through the blood return pipeline was counted. The vitro blood was heated with a blood/fluid warmer under different temperature settings, and the rising speed of blood temperature was recorded. The blood samples were tested for blood routine examination, free Hb and erythrocyte morphology at 0, 15 and 30 minutes. In the process of plateletpheresis in winter, the blood donors′ ear temperature and the skin temperature near the reinfusion needle in the observation group and the controls were measured, and the blood donors were observed for shivering, arm chills, pain or other discomfort. After the blood donation, the thermal comfort was evaluated. 【Results】 There was no difference in the results of routine blood test and plasma free Hb test of vitro blood after warming at 41℃, 42℃ and 43℃ for 0, 15 and 30 minutes (P>0.05), and no change in erythrocyte morphology was found. The skin temperature near the reinfusion needle (before vs. after the start of phlebotomy) was statistically different by applying blood/fluid warmer or not(P<0.05), and no difference in the temperature between the start and end of phlebotomy was observed in the observation group(P>0.05). The vitro blood heating experiment showed that when the room temperature was within 22~24℃, the blood retransfusion speed was (100-120) mL/min; after the application of blood/fluid warmer, the temperature of reinfusion blood could be raised from 27℃ to 33~37℃. The proportion of feeling comfortable and very comfortable and the score of thermal comfort in the blood donors who used the warmer were higher than those in the controls (P<0.05). When the temperature of the warmer was set above 38℃, the average score of thermal comfort of blood donors was above 8. 【Conclusion】 It is safe to apply the blood/fluid warmer during the plateletsapheresis in winter, which can significantly improve the comfort of blood donors and reflect the humanized service of blood stations, and is worth popularizing.

【Objective】 To investigate the practice and benefit of national standardized management of type 2 diabetes in Yulin City. 【Methods】 We recruited the adult type 2 diabetes patients who sought medical help at our hospital from May 2020 to October 2022 as subjects. We collected their basic information (sex and age); measured height, weight, waist and hip circumference, and blood pressure; calculated body mass index (BMI); and detected blood glucose, c-peptide, HbA1c, biomarkers, urinary microalbumin, sensory nerve conduction velocity of lower limbs, ABI, and subcutaneous and visceral fat at the time of MMC recruited and the end of six months. T test and Mann-Whitney U rank sum test were used for measurement data and χ² test or Fisher’s exact probability method for counting data to analyze the data. 【Results】 After 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, and visceral and subcutaneous fat in all the patients decreased, but the level of fasting c-peptide increased compared with the baseline (all P<0.05). Secondly, compared with the baseline, the control rate of HbA1c (35.21% vs. 13.71% ) and the comprehensive control rate (13.97% vs. 7.26% ) were both significantly increased at six months (P<0.05). Thirdly, after 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, TG, TC, and UA were decreased more, while the fasting c-peptide and postprandial c-peptide were increased more in the patients of the HbA1c standard group (HbA1c<7% ) than those of the non-standard group. 【Conclusion】 The multiple benefits of blood glucose, blood lipid, uric acid and islet function can be achieved by taking type 2 diabetes patients into MMC. Meanwhile, the rates of HbA1c control and comprehensively reaching the standard are significantly increased. Therefore, MMC can explore a new way for the management of type 2 diabetic patients in this area.
