Objective To investigate the diagnostic values of different imaging techniques in congenital esophageal atresia and tra-cheoesophageal fistula.Methods Imaging findinfs of 34 infants with congenital esophageal atresia and tracheoesophageal fistula were retrospectively analyzed.34 infants undertook X-ray and esophageal imaging,and 1 7 infants also undertook CT examination.Results Based on Gross classification,there were 2,32,9 and 23 cases for type I,Ⅲ,Ⅲa and Ⅲb,respectively.Coexistence of other de-formity was observed in 10 cases.Plain chest and abdomen X-ray film showed gastric pneumatosis in 32 cases,varied degrees of pneumonia in 25 cases and right upper pulmonary atelectasis in 3 cases.Esophagography showed a cecum in upper esophageal in 34 cases,distal tracheoesophageal fistula in one case.CT examination indicated distal tracheoesophageal fistula and orificium fistulae in 14 cases.Conclusion Combination of X-ray and CT imaging results with clinical symptoms can aid early detection and typing of con-genital esophageal atresia,furthermore provides guidance for operation and finally improves the survival rate of infants.

Aim To investigate the renoprotective effect of berberine in diabetic nephropathy rat model. Methods The rat model of DN was induced by intra-peritoneal injection of streptozotocin ( STZ ) after fed with high sugar and high fat diet for six weeks. The rats were divided into 5 groups randomly, i. e. normal control group, model group, BBR ( 50 mg · kg-1 ) , BBR ( 100 mg · kg-1 ) and BBR ( 200 mg · kg-1 ) treatment group. The fasting blood glucose ( FBG) was evaluated at 2, 4, 6,8 week respectively. The patho-logical changes in the kidney were determined by PAS staining. The expression of vascular endothelial growth factor ( VEGF) was detected by immunohistochemistry and Western blot respectively. Results Compared with normal control group, the value of FBG, SCr, BUN and UTP of model group were sharply increased.
Compared with model group, the value of FBG in ber-berine different dosage treatment groups were signifi-cantly decreased to various degrees, and berberine dif-ferent dosage treatment could decrease the levels of SCr, BUN and UTP in different degree. Berberine could surpress the alterations of pathological changes in the kidneys and downregulate the expression levels of VEGF in the kidney of diabetic rats with nephropathy. Conclusion Berberine could significantly ameliorate the biochemical indicators and renal injury of the model rats through affecting the abnormal expression levels of VEGF in the kidney.

Objective To investigate the detection of multidrug-resistant organisms (MDROs)in a hospital, evaluate the efficacy of multi-disciplinary team(MDT)on management of MDROs,and provide guidance for effective control on MDRO infection.Methods From October 2013 to September 2014,compliance to comprehensive inter-vention measures in clinical departments in different stages as well as detection of MDROs from patients were com-pared respectively.Results Compliance to comprehensive intervention measures showed an overall upward trend from the fourth quarter of 2013 to the first,second,and third quarters of 2014,difference was statistically signifi-cant (all P <0.001 ).From the fourth quarter of 2013 to the third quarter of 2014,the percentage of the major MDRO strains in the same species of bacteria were:methicillin-resistant Staphylococcus aureus (MRSA)52.34%, 45.45%,48.95%,and 26.25% respectively;carbapenem-resistant Acinetobacter baumannii (CRAB)64.42%, 63.07%,59.87%,and 43.09% respectively;multidrug-resistant Pseudomonas aeruginosa (MDRPA)42.11 %, 41 .82%,29.33%,and 17.52% respectively;the detection rate of MRSA,CRAB,and MDRPA showed an overall downward trend,difference among different stages were statistically significant (all P <0.001 ).Detection rates of carbapenem-resistant Enterobacteriaceae (CRE)and vancomycin-resistant Enterococcus (VRE)were both low (<5%),difference among different stages were not statistically significant (all P >0.05).Conclusion MDT on man-agement of MDROs is helpful for reducing the emergence and spread of MDROs.

Aim To investigate the effect of berberine on the expression of nephrin, podocin and intergrinα3β1 in diabetic nephropathy ( DN ) rat model, and further probe in to the renoprotective effects of berber-ine and its potential mechanisms. Methods The rat model of DN was induced by intraperitoneal injection of streptozotocin ( STZ ) after fed with high-sugar and high-fat diet for six weeks. The rats were assigned into 6 groups randomly: normal control group, DN model group, BBR (50,100 and 200 mg·kg-1 ) treatment group and enalaprilat positive control group ( 1 mg · kg-1 ) . The distribution and expression of kidney podocyte related proteins nephrin, podocin and interg-rinα3β1 were detected by immunohistochemical meth-od following electron microscopy observation ( × 1000 ) and high magnification observation( × 400) and West-ern blot. Results The podocyte related protein neph-rin, podocin and intergrin α3β1 were mainly distribu-ted in podocyte, but slightly different. Compared with normal control group, the expresion of podocyte related protein nephrin, podocin and intergrin α3β1 was de-creased obviously; compared with model group, BBR (100 and 200 mg·kg-1 ) treatment group could sig-nificantly suppress the abnormalities of pathological changes of the kidney and upregulate the expression levels of podocyte specific protein nephrin, podocin and intergrin α3β1 in the kidney of diabetic rats with nephropathy. Conclusions Berberine could alleviate the abnormalities of kidney pathological changes and proteinuria production in the DN model rats, which may be related to the upregulation of the expression of the podocyte proteins nephrin, podocin and intergrinα3β1.

Objective:To analyze the influencing factors of clozapine plasma concentration in patients with mental disorders after oral administration, so as to provide reference for individualized treatment.Methods:Retrospective analysis was made on 221 inpatient reports of Clozapine blood concentration monitoring in the Therapeutic Drug Monitoring Laboratory (TDM) of the Pharmacy Department of the Chaohu Hospital Affiliated to Anhui Medical University from January to October 2021, and information such as patient gender, age, body mass index (BMI), smoking history, clozapine dose, combined drug use and blood concentration monitoring results were collected; Single factor analysis of variance and binary logistic regression were used to analyze the monitoring results of clozapine blood concentration in patients with mental disorders and its influencing factors.Results:Among 221 monitoring reports, 74 cases (normal concentration group) had clozapine plasma concentration within the effective plasma concentration range (350-600 ng/ml), 103 cases (low concentration group) were lower than the effective plasma concentration range (<350 ng/ml), and 44 cases (high concentration group) were higher than the effective plasma concentration range (>600 ng/ml). The results of single factor analysis of variance showed that there were statistically significant differences in daily dose of clozapine, standard dose, smoking history, course of disease, and abnormal liver function of patients in different blood concentration groups of clozapine (all P<0.05). The most frequently used antipsychotic drugs in 221 patients with clozapine were sodium valproate, amisulpride, aripiprazole and lithium carbonate in turn. The proportion of clozapine combined with ≥2 antipsychotics in the normal concentration group was higher than that in the low concentration group and the high concentration group, and the difference was statistically significant ( P<0.05). The results of binary logistic regression analysis showed that the combination of one antipsychotic drug and ≥ two antipsychotic drugs might help the blood concentration of clozapine in patients with mental disorders reach the target concentration (350-600 ng/ml), and the combination of two drugs was more beneficial [ OR(95% CI): 1.795(0.753-4.282)], with a statistically significant difference ( P<0.05). Conclusions:Clozapine plasma concentration varies greatly among individuals, and the therapeutic window is narrow. It is necessary to adjust the dosage in combination with the basic information and clinical information of patients, and regularly monitor the plasma concentration, so as to achieve the safety and effectiveness of individualized drug use.
