Objective To explore the main pathogenic bacteria and sensitive antibiotics and related factors in bile in patients with acute biliary pancreatitis (ABP).Methods 176 patients with ABP from September2015 to September 2017 were selected as the study subjects.Bile was collected for bacterial culture and antibiotic susceptibility testing.The relationship between different obstruction sites and total bilirubin levels and bacterial detection rates was compared.Results The positive rate of bacterial culture was 68.18％.There were 155 aerobic bacteria and 25 anaerobic bacteria.Among the G-bacteria, E.coli (62.85％) accounted for the largest proportion, Enterococcus (12.26％) accounted for the highest proportion of G+ bacteria, and Bacteroides fragilis (52.00％) accounted for the majority of anaerobes..The sensitivity of G-bacteria to meropenem, cefepime and ciprofloxacin was greater than 80％, which was 96.77％, 91.13％ and 84.68％, respectively.The sensitivity rate of G+ to vancomycin was 100％, and the sensitivity rate to meropenem, tetracycline, and azithromycin was higher than 80％.The positive rate of bacterial culture in high obstruction was significantly higher than that in middle-low obstruction (P＜0.05).The low-level group was significantly higher than the middle-level group and the high-level group (P＜0.05), and the middle-level group was significantly higher than the high-level group (P＜0.05).Conclusion For the early anti-infection treatment of ABP patients, aminoglycosides+third-generation cefquinolones+ metronidazole can be used for treatment.Patients with high obstruction and low TB levels need to strengthen anti-infection treatment.

OBJECTIVETo investigate the apoptosis induced by manumycin in U937 and HL-60 cell lines, and to explore the role of mitochondria apoptotic pathway in manumycin-inducing apoptosis.

METHODSLeukemic cells line U937 and HL-60 were treated by manumycin at 2 micromol/L for different time. Apoptosis of leukemia cells was detected by flow cytometry. The cytosolic proteins were extracted using a digitonin buffer. The protein expression of cytochrome C, caspase-9, caspase-8, and caspase-3 were determined by western blot. Mitochondrial membrane potential was detected by JC-1.

RESULTSIn U937 and HL-60 cells, manumycin induced mitochondrial depolarization after 6 h treatment. The average red/green fluorescence ratios at 6 h were significantly (P < 0.01) lower than those at time 0, being 0.51 +/- 0.07 and 0.41 +/- 0.06 for control group respectively. Manumycin induced cytochrome C release from the mitochondria into the cytosol after 6 h treatment, and activated caspase-9, caspase-8, and caspase-3 after a 16h treatment. The broad-spectrum caspase-inhibitor Z-VAD-fmk at 50 micromol/L was able to inhibit caspase cleavage completely, but only reduced the manumycin-induced apoptosis rates by 51.69% and 56.47% in U937 and HL-60, respectively.

CONCLUSIONManumycin induced apoptosis in U937 and HL-60 cell lines via mitochondria apoptotic pathway.

Objective To measure the transaction costs of compact county medical alliance and propose counter-measures.Methods Based on Williamson-Zhang Wuchang analysis paradigm,it established the measure matrix of transaction cost of compact county medical alliance.Through the typical sampling method,the medical community of D city in Haixi Prefecture,Qinghai Province was selected as a research example to carry out an empirical study.Results The total transaction cost of the compact county medical community was 6 292 500.00 yuan,the transac-tion cost of the leading hospital was 6 234 300.00 yuan,accounting for 99.07％,and the special investment of the leading hospital reached to 5 887 100.00 yuan,accounting for 94.43％.The total transaction cost of the 298 referred patients was 308 400.00 yuan,and the average transaction cost per patient was 1 035.05 yuan.Conclusion The transaction costs of compact county medical alliance was generally high,most of which was borne by the leading hospital,and the patients also had to bear the corresponding transaction costs.In the next stage,the transaction costs should be dealt with from three aspects,including recognizing the secrecy and universality of the transaction costs,establishing economical system supply and establishing a sound compensation mechanism.
