OBJECTIVE To investigate the bacterial distribution and sensitivity to antibiotics isolated from infected patients in emergency department. METHODS The antimicrobial susceptibility tests to commonly used antibiotics were performed to the specimen send by the emergency and respiratory departments in our hospital in 2007.The data were analyzed respectively. RESULTS Totally 340 strains were isolated in emergency department and 366 strains were isolated in respiratory department.The main bacteria isolated were similar in the two departments such as Acinetobacter baumannii,Pseudomonas aeruginosa,Staphylococcus aureus and Escherichia coli,but their sensitivities to antibiotics were different. CONCLUSIONS Bacterial distribution of the infected patients in emergency department is similar to respiratory departments,but their sensitivities to antibiotics are different.

Objective:To investigate the value of renal glucose threshold and related factors in patients with type 2 diabetes mellitus.Methods:According to the cut-off point of normal renal glucose threshold(RT G 8.9-10 mmol/L), 107 patients with type 2 diabetes mellitus hospitalized in the Endocrinology Department of our hospital were divided into three groups: high RT G group(RT G>10 mmol/L), medium RT G group(8.9 mmol/L≤RT G≤10 mmol/L), and low RT G group(RT G<8.9 mmol/L). The clinical data and biochemical characteristics of each group were collected and analyzed. Results:The proportions of patients with high, medium, and low RT G of type 2 diabetes mellitus were 56%, 29%, and 15%, respectively. There were significant differences in RT G value, age, course of disease, body mass index(BMI), fasting plasma glucose(FPG), HbA 1C, total cholesterol(TC), serum creatinine, mean blood glucose(MBG), and 24-hour urine glucose between high and medium RT G groups. RT G, gender, BMI, FPG, HbA 1C, TC, and MBG in patients with high RT G group were different from those in low RT G group. Only RT G revealed a difference between medium and low RT G groups. Correlation analysis showed that RT G was positively correlated with gender, age, BMI, HbA 1C, TC, and low density lipoprotein-cholesterol(LDL-C). Regression analysis showed that BMI, HbA 1C, and LDL-C were the related factors affecting the RT G of patients with type 2 diabetes. Conclusion:There is a larger proportion of patients with high RT G in type 2 diabetes mellitus. Their BMI, HbA 1C, and LDL-C are associated with RT G in the patients with type 2 diabetes mellitus.

Objective This study investigated high fat diet influence on the changes of vitamin D receptor (VDR) expression and endothelial nitric oxide synthase (eNOS) in apolipoprotein E-deficient(apoE-/-) mice.MethodsApoE-/- mice and C57BLP6J mice were divide into two groups (normal control and high fat diet),high fat diet group were feed high fat feedstuff.Plasma 25-(OH)D levels were determined by competitive protein binding radioimmunity,VDR expression were determined by immunofluorescence and reverse transcription-polymerase chain reaction.The levels of NO and eNOS were determined by nitrate reductase.ResultsCompared with normal control group,high fat diet caused more severe dam-age of atherosclerosis in wild type mice and apoE-/- mice.In apoE-/- mice,the levels of plasma 25-(OH)D were significantly decreased [(26.44±1.28) ng/mL,(22.68±2.07)ng/mL,(17.46±2.22)ng/mL,(15.88±0.97)ng/mL,P＜0.01],the expression of VDR protein and mRNA were significantly increased[VDR :0.244±0.088,0.346±0.132,0.547±0.128,0.768±0.162;VDRmRNA:0.228±0.083,0.375±0.103,0.451±0.117,0.597±0.131,P＜0.01],and the levels of NO and eNOS were significantly increased[NO:(39.74±4.81)μmol/L,(48.1±5.24 )μmol/L,(67.34±6.14 )μmol/L,(86.74±8.05)μmol/L;eNOS:(8.6±0.77 )U/L,(12.28±1.42)U/L,(15.96±0.92)U/L,(18.68±1.15)U/L,P＜0.01].These changes were more significantly in high fat diet group(P＜0.01).ConclusionsThere were abnormalities of plasma 25-(OH)D level,VDR expression and the level of NO and eNOS in apoE-/- mice.These changes were more significantly in high fat diet group.

Objective:To compare the complications associated with various urinary flow diversion methods and identify the factors that contribute to the decline in renal function after radical total cystectomy for myoinfiltrating urothelial carcinoma.Methods:This study conducted a retrospective analysis on the clinical data of 46 patients with pathologically confirmed muscle-invasive bladder cancer.The patients underwent laparoscopic radical cystectomy with either ileal conduit diversion(n=21)or ureterocutaneous diversion(n=25)between January 2017 and December 2021.Perioperative data, postoperative pathology, postoperative complications, and follow-up results were compared between the two groups.Results:The study found significant differences between the two groups in terms of age[(67±6)years vs.(73±8)years, t=3.132, P=0.003], Charlson comorbidity index adjusted for age[(3.80±1.15) vs.(4.52±1.03), t=2.223, P=0.031], prognostic nutritional index[(48.81±5.74) vs.(43.64±4.74), t=3.347, P=0.002], operation time[(449±108)minutes vs.(326±130)minutes, P=0.001]], hospital stay[(20.1±11.1)days vs.(13.3±5.2)days, t=2.762, P=0.008], proportion of Clavien grade 3 or higher complications within 3 months after surgery(4/21 vs 0/25, χ2=2.105, P<0.05), and proportion of stoma-free patients(18/21 vs.5/25, χ2=6.373, P<0.01). According to Logistic multivariate analysis, perioperative blood transfusion and urinary tract infection were identified as independent risk factors for renal function decline 12 months after surgery.Escherichia coli was found to be the most common bacteria cultured from urinary tract infections in both groups after surgery. Conclusions:Laparoscopic radical cystectomy with ureterocutaneous diversion offers benefits such as shorter hospital stays and fewer perioperative complications for older and frail patients.However, a higher proportion of patients may require ureteral stenting.It is important to note that perioperative blood transfusion and urinary tract infection are major risk factors for renal function decline following radical cystectomy.

Danshen, the dried roots and rhizomes of Salvia miltiorrhiza Bunge (S. miltiorrhiza), is widely used in the treatment of cardiovascular and cerebrovascular diseases. Tanshinones, the bioactive compounds from Danshen, exhibit a wide spectrum of pharmacological properties, suggesting their potential for future therapeutic applications. Tanshinone biosynthesis is a complex process involving at least six P450 enzymes that have been identified and characterized, most of which belong to the CYP76 and CYP71 families. In this study, CYP81C16, a member of the CYP71 clan, was identified in S. miltiorrhiza. An in vitro assay revealed that it could catalyze the hydroxylation of four para-quinone-type tanshinones, namely neocryptotanshinone, deoxyneocryptotanshinone, and danshenxinkuns A and B. SmCYP81C16 emerged as a potential broad-spectrum oxidase targeting the C-18 position of para-quinone-type tanshinones with an impressive relative conversion rate exceeding 90%. Kinetic evaluations andin vivo assays underscored its highest affinity towards neocryptotanshinone among the tested substrates. The overexpression of SmCYP81C16 promoted the accumulation of (iso)tanshinone in hairy root lines. The characterization of SmCYP81C16 in this study accentuates its potential as a pivotal tool in the biotechnological production of tanshinones, either through microbial or plant metabolic engineering.
