OBJECTIVE: To probe into the status quo and the tendency of the application of intravenous infusions. METHODS: Data on the application of intravenous infusions in one of the tertiary Grade A comprehensive hospital in 1996, 1999, 2002 and 2004 were analyzed statistically. RESULTS: The variety of infusion, the total quantity and the total amount of money of infusions increased year by year,the total consumption sum of infusions accounted for 10% of that of the whole year drugs; the majority of which were the consumption of nutritional and dielectric medicines, of which, glucose and sodium chloride injections accounted for 74% of the total; the infusion of treatment type increased fast, much as in cases of anti - infec-tives; the drug expense for each bottle of infusion increased year by year, the amount of money involved in infusion drugs accounted for 60% of the total year round drug consumption sum. CONCLUSION: There is an upward trend in both the quantity and consumption sum of infusions.

OBJECTIVE:To provide reference data for well understanding of high cost to access medical service for diabetic patients and controlling increase of medical costs.METHODS:Average daily cost of diabetic drugs in 1998 was compared with in 2008.At the same time it was compared with GDP and per-captia disposable income(PCDI).RESULTS:GDP,PCDI,consumption sum of total drugs and consumption sum of diabetic drugs in 2008 respectively were 3.78 times,3.11 times,3.87 times,2.73 times compared with in 1998.Amount of and daily average expenses of insulin respectively were 3.46 times,1.23 times;DDDs and daily average expense of oral hypoglycemics respectively were 1.69 times,1.41 times,compared with in 1998.Incremental rate of daily average expense of insulin injection and oral hypoglycemics were lower than that of PCDI.The daily average expense was increased as a result of the use of joint venture import drugs and new drugs and increase of diabetic patients.CONCLUSION:Incremental rate of daily average expense of diabetic drugs is lower than that of PCDI.High cost to access medical service for diabetic patients isn't equal to high cost of drugs.Many factors related should be considered from the point of view of society.

OBJECTIVE:To systematically evaluate the efficacy and safety of modified infusion(2-4 h infusion or continuous 24 h infusion)versus traditional infusion(0.5-1 h infusion)of meropenem in the treatment of severe infectious,and to provide evi-dence-based reference for clinic treatment. METHODS:Retrieved from Medline,CJFD,VIP database and Wanfang database, modified infusion(test group)versus traditional infusion(control group)of meropenem in the treatment of severe infections were collected,and Mata-analysis was performed by using Rev Man 5.0 statistical software after extracting data and evaluating quality. RESULTS:A total of 13 studies were included,involving 1 012 patients. Results of Meta-analysis showed the effective rate [RR=1.25,95%CI(1.10,1.43),P<0.001] and bacterial eradication rate [RR=1.25,95%CI(1.05,1.48),P=0.01] in test groups were sig-nificantly higher than those of control group,and there were no significant differences in the mortality rate [RR=0.74,95%CI (0.46,1.18),P=0.21] and incidence of adverse reactions [RR=0.81,95%CI(0.48,1.39),P=0.45]. CONCLUSIONS:Compared with traditional infusion of meropenem,extended or continuous infusion can improve efficacy in the treatment of severe infections, with similar safety. Due to methodology limit of included studies,large-scale and high quality RCT are required for further valida-tion of the conclusions.

In order to isolate Mycoplasma hyopneumoniae(Mhp)and select virulent strains with high growth titer from the isolates to acclimate at high temperature to obtain attenuated strains.Forty lung and trachea tissues were aseptically collected from pigs suspected of Mhp in several farms in Nanyang City.A total of 6 strains of Mhp were isolated through pathogen isolation,colony observation,PCR identification and sequencing.For each isolate,round colonies with neat edges,dewdrop like particles and ridges in the center were observed on solid medium.PCR could amplify the target gene bands of each isolated P36.After sequencing,the amplified products were compared with the gene sequences of ATCC 25934 reference strain(J strain)P36 registered in NCBI,and the homology was more than 99％.The growth titer of TH-1 strain measured by CCU experiment could reach 1011 CCU/mL,which showed a high growth titer.TH-1 strain was selected for continu-ous passage at high temperature(40 ℃)in vitro to obtain different passages(P50,P1 00,P1 50).TH-1 P150 still had a higher growth titer(1010 CCU/mL)at 40 ℃ growth temperature.TH-1 P1,P50,P100 and P150 were injected into the trachea to infect 25-day-old weaned piglets,and the re-sults of virulence evaluation showed that 4 pigs(4/5)in the P1 infection group had typical"meat or shrimp meat"lesions,and serious monocyte and lymphocyte infiltration were found in the lung HE pathological sections,and the cilia were clutter-tangled,shortened and exfoliated.P150 infec-tion group did not show typical Mhp characteristic lesions,lung HE and tracheal scan sections did not show microscopic pathological changes,indicating that TH-1 was a virulent strain,but its viru-lence was continuously decreased after continuous in vitro passage,and TH-1 P150 was a low-viru-lence strain.TH-1 P150 strain,as a attenuated vaccine strain,has good immunogenicity,and the av-erage reduction rate of pneumonia disease after immune challenge was 83.3％.In conclusion,a low-virulence strain with high growth titer(TH-1 P150)was obtained by continuous passage at high temperature in vitro for the first time,and its immunogenicity was good,which laid the foundation for further research and development of Mhp attenuated vaccine.
