AIM: To describe and evaluate the clinical characteristics, treatment management and clinical outcomes of ceftazidime-avibactam (CZA) in the treatment of patients with multidrug-resistant gram-negative bacterial (MDR-GNB) infections. METHODS: A retrospective cohort study was performed on patients hospitalized in the Affiliated Hospital of Xuzhou Medical University from September 2019 to December 2021. Adult patients who received CZA for ≥ 72 hours consecutively were eligible for inclusion. The primary outcome was clinical failure, defined as a composite of 30-day all-cause mortality, microbiological failure and / or failure to resolve or improve signs and symptoms of infection during treatment with CZA. RESULTS: A total of 198 patients with MDR-GNB infections were described and evaluated, including 132 in the carbapenem-resistant Enterobatceriaceae (CRE) cohort and 66 in the Pseudomonas spp. cohort. The main infection sites were lung infection (92.42%), abdominal infection (10.61%), and intracranial infection (10.61%), among which 63 patients (31.82%) were positive for blood culture. Clinical failure, 30-day all-cause mortality and microbiological failure occurred in 61 (30.81%), 33(16.67%) and 11(5.56%) patients, respectively. Body mass index (BMI), acute physiology and chronic health evaluation scoring system (APACHE Ⅱ) and polymicrobial infections were positively associated with clinical outcome failureadjusted OR 1.109, 95%CI 1.017, 1.209; adjusted OR 1.071, 95%CI 1.015, 1.129; adjusted OR 2.844, 95%CI 1.391, 5.814, however, initiation of CZA within 48 hours of admission was protective (adjusted OR 0.424, 95%CI 0.205, 0.879). A total of 15 patients had adverse reactions possibly related to CZA, including 2 cases of rash, 6 cases of nausea and vomiting, and 7 cases of antibiotic-related diarrhea. CONCLUSION: CZA can be used to treat infections caused by a range of MDR-GNB, including Pseudomonas spp. and CRE.

AIM: To explore which variables can predict the weight response to exenatide and to individualize specific therapies for patients with type 2 diabetes mellitus (T2DM) who need treatment with exenatide. METHODS: We performed a study among T2DM patients who were treated with exenatide twice daily for at least 12 months from January 2017 to December 2020. Data of the height, weight, body mass index (BMI) calculated, and HbA1c, fasting plasma glucose (FPG), postprandial plasma glucose (PPG), fasting serum insulin (FINS), postprandial serum insulin (PINS), blood lipids and concurrent diabetic medications at baseline, 3 months, 6 months and 12 months after exenatide initiation were collected. Patients were categorized into two cohorts based on weight loss ≥3%: responders and non-responders. The binary logistic regression analysis was used to identify the major variables of weight response to exenatide. RESULTS: The duration of diabetes in the responder group was shorter than that in patients in the non-responder group (P<0.05). For patients in the responder and non-responder groups, there was a significant decrease in weight, BMI, HbA1c, FPG, PPG, homeostasis model assessment of insulin resistance (HOMA-IR) and increase in homeostasis model assessment for beta cell function (HOMA-B) compared with the prarameters before treatment with exenatide (P<0.001). The baseline weight and baseline HbA1c were associated with weight loss after 6 months of treatment with exenatide (P<0.05). CONCLUSION: Baseline weight and HbA1c improvement were positively correlated with weight loss after 6 months of treatment with exenatide and the major predictors of weight response to exenatide.

This study attempts to develop a reference substance for the live bacteria count of Streptococcicosis live vaccines in order to evaluate the validity of live bacterial count in inspection and testing. We prepared a batch of live Streptococcus suis reference substance for live bacterial count, tested their physical property, purity, vacuum degree, remaining moisture, and determined their homogeneity, thermal stability and transportation stability. Moreover, we organized collaborative calibration to assign count values to the reference substance and determine the shelf life of the reference substance in 12 months. The results showed that the physical property, the purity, the remaining moisture and the vacuum degree of the reference substance were all in compliance with the requirements of the Chinese Veterinary Pharmacopoeia. The homogeneity test showed that the coefficient of variation of the count of the reference substance was less than 10%, indicating a good homogeneity. Transportation stability test showed that the reference substance remained active after 72 h transportation in summer and winter with the package of styrofoam boxes and ice packs. Thermal stability test showed that the reference substance could be stored for up to 3 months at -20 °C, or up to 21 days at 4 °C. According to the collaborative calibration, the reference vaccine was assigned a count value range of (8.5-12.1)×107 CFU/ampoule. The shelf life test showed that the reference substance was stable for 12 months when stored at -70 °C. The reference substance could provide a reference for the live bacterial count of Streptococcicosis live vaccines. Moreover, it could also be used as a reference to evaluate the quality of corresponding agar media.

Objective To investigate the use of parenteral nutrition preparations in Jiangsu Province,and to provide reference for the standardized management of parenteral nutrition preparations.Methods 720 cases using parenteral nutrition preparations from January 2017 to June 2017 in the department of general surgery of 12 hospitals in Jiangsu province were selected.The rate of nutritional risk screening,the indications of parenteral nutrition,the way of infusion,the rationality and economy of the prescriptions were retrospectively evaluated.The calorie,amino acid content,non-protein calorie/nitrogen ratio,glycolipid ratio and cation concentration of the patients received total parenteral nutrition were calculated.Results The total costs of parenteral nutrition preparations of 720 cases were 1.614 1 millions,and 346 cases did not have the indications for parenteral nutrition.The results of prescription comment showed that only 16 patients were screened for nutritional risk by Nutritional Risk Screening 2002 tool at admission.544 cases were intravenous dripped with amino acid and fat emulsion from peripheral vein.In the 176 total parenteral nutrition prescriptions,there were 39 non-protein calorie/nitrogen ratio cases,15 glycolipid ratio cases,69 cation concentration cases,61 calorie cases and 32 amino acid content cases failing to comply with the recommendation of the guidelines.Only 31 total parenteral nutrition prescriptions were completely reasonable.Conclusion The costs of parenteral nutrition preparations used in hospitals of Jiangsu are high but the rate of rationality is low.Nutrition support team should be established to regulate the use of parenteral nutrition preparations and save medical resources.

Objective To study in the correlation of the laboratory markers of coagulation,fibrinolysis and thrombosis in patients with sepsis and SOFA score,the procalcitonin (PCT) concentration and seven-day survival rate.Methods From February 2017 to March 2018,119 patients with sepsis admitted in ICU and another 119 patients with non-sepsis undergoing selective surgery were enrolled as control in this study.APTT (activated partial thromboplastin time),PT-INR (prothrombin time-international normalized ratio),FIB (fibrinogen),AT-Ⅲ (antithrombin Ⅲ),D-Dimer,FDP (fibrinogen degradation products),sTM (soluble thrombomodulin),TAT (thrombin antithrombin complex),PIC (plasmin-a2 plasminogen inhibitor complex) and t-PAI-C (tissue plasminogen activator and its inhibitor complex),were simultaneously monitored at admission.The correlation between the given laboratory markers mentioned and SOFA score,the PCT concentration and seven-day survival rate were analyzed with the Spearman correlation analysis.Results (① In the patients with sepsis,a positive correlation between SOFA score and sTM,t-PAI-C,TAT respectively was found,and a negative correlation between SOFA score and PLT (platelet count) was observed,and no correlation between SOFA score and PIC was noticed.(②) A positive correlation between PCT and sTM,t-PAI-C respectively was significant,a negative correlation between PCT and PLT was marked,and no correlation between PCT and AT-Ⅲ,TAT,PIC respectively was found.(③) A negative correlation between seven-day survival rate and sTM,t-PAI-C and TAT respectively was obvious,a positive correlation between seven-day survival rate and AT-Ⅲ,PLT respectively was occurred,and no correlation between seven-day survival rate and PIC was determined.Conclusions Soluble thrombomodulin (sTM),thrombin-antithrombin (TAT),antithrombin Ⅲ (AT-Ⅲ) and tissue plasminogen activator inhibitor complex (t-PAI-c) were good clinical monitoring indicators of coagulation disorder in patients with sepsis,which were the representative of the endothelial cell damage with highly activated coagulation,relatively insufficient anti-coagulation function and poor fibrin degradation ability.These were good adjuvants to PLT,INR and APTT for core diagnostic criteria of coagulation disorder in sepsis.

Objective: To evaluate the therapeutic effect and security of Buyang Huanwu decoction in treatment of the ischemic stroke recovery. Methods: We retrieved the relevant articles of random and semi- random control trials in treating ischemic stroke recovery using Buyang Huanwu decoction, published in China National Knowledge Infrastructure (CNKI), the Wanfang Data, the Weipu Information Resources System, the Chinese Biomedical Literature Database (CBM), Cochrane Library, PUBMED and MEDLINE from the date of establishment until to March 2018. The quality of studies was evaluated according to the Cochrane Reviewers?? handbook 5.1, and the study was carried out using Cochrane system assessment methods. Statistical analysis was performed with Rev Man 5.3. Results: Altogether 39 studies and 3539 cases of ischemic stroke recovery were enrolled. In terms of clinical efficacy, the difference between Buyang Huanwu Decoction and Western Medicine conventional therapy in the treatment of ischemic stroke was significantly different from that of conventional western medicine therapy [RR =1.26, 95％CI (1.20, 1.31), Z =10.05, P ＜ 0.00001], and the difference between Buyang Huanwu Decoction and other Chinese patent medicines was statistically significant [RR =1.12, 95％CI(1.06, 1.19), Z =3.82, P =0.0001]; neurological deficit NIHSS score [MD =-2.55, 95％CI (-3.10, -2.01), Z =9.20, P ＜ 0.00001]; clinical neurological deficit score (CSS) [MD =-3.85, 95％CI (-5.21, -2.50), Z =5.56, P ＜ 0.00001]; limb motor function score (FMA) [MD =6.10, 95％CI (1.19, 11.01), Z =2.43, P =0.01]; Barthel Index of Daily Living Activity Scale [MD =9.09, 95％CI (6.95, 11.23), Z =8.33, P ＜ 0.00001]; In terms of improving blood rheology index, serum peroxide lipid (LPO), serum superoxide dismutase (SOD) and other biochemical indicators, due to the small number of studies, it may have a certain effect. Most studies did not report adverse reactions. Conclusion: Based on the existing clinical evidence, combination of Buyang Huanwu decoction and western medicine has higher clinical efficacy than western medicine alone for the ischemic stroke recovery. Due to the limited methodological quality of the included studies, more high- quality RCTs with large scale are needed to increase the strength of the above evidence.

Objective To explore the risk factors of postoperative delirium among ICU patients. Methods Meta analysis was done by retrieving POD-relevant literature through electronic databases.The included papers by quality assessment were analyzed by Revman 5.3. Results 14 papers,10 English and 4 Chinese,were included for the analysis,involving 5,661 patients.Meta-analysis showed that the alcoholism, renal function impairment, mechanical ventilation, stroke, hypertension and diabetes, LVEF<50% and emergency operation were the risk factors of postoperative delirium(all P<0.05). Conclusions The risk factors of postoperative POD in ICU patients include alcoholism,renal function impairment,mechanical ventilation,stroke,hypertension and diabetes,LVEF<50% and emergency operation. Medical staffs should pay more attentions to the intervention into those risk factors in order to reduce the incidence rate of POD and improve the quality of clinic treatment.
