OBJECTIVE: To optimize the preparation technology for the lovastatin capsules.METHODS: Orthogonal test was used to optimize the conditions for the technology of preparation meanwhile a dissolution test was conducted.RESULTS: According to the results of the single factor analysis and orthogonal test,the optimal condition for the lovastatin capsules were as follows: agglomerant: 10%PVP;disintegrator: CMS-Na was used by combining exterior and interior addition(2∶1);stuffing capsule by granules;wetting agent of twice granulating: 75% alcohol.The 30 min dissolution rate of the capsules prepared in the optimized technology reached above 92%.CONCLUSION: This preparation is stable in technology,reproducible and with high dissolution rate.

Objective To explore the influences of metoprolol in the treatment of diastolic blood pressure on blood glucose.Methods 120 patients with diastolic blood pressure were selected and divided into the research group and the control group,each group 60 cases.The research group was given metoprolol,and the control group was given pelodipine.The treatment time was 12 months.In treatment process,bload glucose and pressure was regularly detected and compared between the two groups.Results After treatment,the diastolic blood pressure of the two groups was lower than that before treatmen(all P ＜ 0.05),but the difference of the diastolic blood pressure between the two groups had no statistical significance before and after treatment(all P ＞ 0.05).The fasting blood glucose(GLU),P2hPG(P2hPG) of the two groups in 1,3,6 months had no obvious difference with those before treatment,but after 12 months the treatment,P2hPG,GLU of the research group was(6.23±0.89) mmol/L,(7.46±0.71) mmoL/L,respectively,and was higher than those before treatment[(4.97±0.52) mmol/L,(5.21±0.69) mmol/L]and those of the control group at the same period[(5.13±0.48)mmol/L,(5.16±0.67) mmol/L(all P＜0.05).Conclusion Metoprolol in the treatment of diastolic blood pressure had good effect.Long term use of drugs(1 year or more) could increase blood glucose levels,but had no other clinical damage,and the safety was good.

Objective To profile the types of bacteria in bile culture and study their antibiotic sensitivity pattern in patients with varying de-grees of acute cholangitis and to provide data guidance for the prevention and treatment of bacterial infection.Methods The clinical data of 230 patients with acute cholangitis who were admitted to our hospital from April 2010 to April 2014 were retrospectively analyzed.Classifica-tion of pathogenic bacteria and the antibiotic sensitivity test in bile cultures were performed using VITEK 2 Compact Biomerieux microbiologi-cal system.Results Within the 230 patients,172 tested positive for biliary bacteria,and the positive rate was 74.78%(172/230).There were 237 strains of pathogenic bacteria,including 135 strains of Gram-positive bacteria (56.96%),comprised mainly of Enterococcus and Staphylococcus aureus,96 strains of Gram-negative bacteria (40.5 1%),comprised mainly of Pseudomonas aeruginosa,Escherichia coli, and Klebsiella pneumonia,and 6 strains of fungi (2.53%),comprised mainly of yeast.Significant difference in the positive rate of bacteria was detected between patients with mild and severe cholangitis (χ2 =4.58,P =0.028).Gram-negative bacteria were the predominant i-solates in patients with mild and moderate acute cholangitis,while multiple bacterial infection was more common in patients with severe cholangitis.Biliary bacteria had a higher rate of susceptibility to vancomycin,imipenem,and amikacin compared with other antibiotics. Conclusion Gram-positive bacteria are the predominant pathogens in acute cholangitis.Early detection,immediate intervention,and ac-curate drug susceptibility test should be implemented at regular intervals to direct effective clinical therapy.

The hospital the authom work with, the first one to undergo the second-cycle nation-wide hospital evaluation, was assessed by a third party and the hospital evaluation experts. The two cycles of hospital evaluation were entirely different in historical background, priorities and procedures. The evaluation standards for the second cycle, which were on a par with internafional ones, set the right track of development for medical institutions, emphasizing quality, security, service and performance and highlighting the delivery of quality patient care. The gains from the second-cycle hospital evaluation can be summarized as follows: more highly emphasized continuous improvement of service quality, enhanced awareness of people-oriented management, reinforced medical quality and medical security control, heightened hospital infection control, greater capability of responding to emergencies, and strengthened for-malation of hospital rules and regulations. In the end five suggestions are put forward with regard to the second-cycle hospital evaluation.

Objective To study the therapeutic effect of pulse-activating injection on acute poisoning by pa-raquat(PQ). Methods 50 Sprague-Dawley (SD) rats were randomly divided into five experimental groups: blank group, negative control group, positive control group, low-dose pulse-activating injection group (LDG), and high-dose pulse-activating injection group(HDG) (n = 10 for each group). Blank group were injected with normal suline,30 ml/kg,and other groups were established as acute paraquat poisoning models. Macroscopic and histopathological ex-aminations were performed and biological indexes were measured for the lung specimens. The indexes included lung wet weight/dry weight,the rats of neutrophils and protein content in the pulmonary alveolar lavage fluid. In the mean time, the level of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) both in plasma and bronchoalveolar lavage flui(BALF) were detected. Results Compared with that in negative control group,lung congestion and lung edema of LDG group were mitigated; and the MDA level decreased from (5.04± 0.50) nmol/ml,(1. 19±0.18) nmol/ml to (4.04±0.21) nmol/ml,(0.79±0.04) nmol/ml both in plasma and BALF;the SOD activities were increased from (123.30±20. 39) U/ml, (26.43±2.22) U/ml to (277.09± 11.66) U/ml,(37.10± 2.49) U/ml as well; the GSH-Px activities were increased from (1796.63 ±81. 12) U/ml, (598.24 ± 62.50) U/ml to (2151.54 ± 148.32) U/ml, ( 1788.44 ± 175.11 ) U/ml as well ( P < 0. 01 ). Conclusions Administration of pulse-activating injection could improve the lipid peroxidation damage caused by a-cute poisoning of PQ.

Objective To summarize the experience of surgical treatment and to explore the oper-ation method choice of ascending aortic aneurysm caused by Marfan Syndrome. Methods The clinical da-ta of 16 patients from 2005 January to 2011 November were retrospectively analyzed. Results Among all, there was no operative mortality,but 6 cases of early postoperative complications(37. 5%),including 2 ca-ses of arrhythmia,2 cases of pulmonary infection,1 case of renal insufficiency and 1 case of pneumothorax. The follow-up time was 12~63(25 ± 9)months. During follow-up,2 patients died(12. 5%),1 due to rup-tured abdominal aortic aneurysms and 1 due to renal failure. Besides there were 2 cases of anticoagulation complications and 1 case of coronary heart disease. Conclusion Although sparing aortic root replacement of aortic valve has similar curative effect as Bentall operation and avoids the mechanical valve-related com-plications,the indications are relatively strict. Bentall operation is still the first choice for severe patients.
