Through analyzing medical personnel's duty under Bio-psycho-social Medical Mode, this paper states that medical personnel's duty should be emphasized not only on preventing and curing diseases, but also on solving patients' psychological problems.Therefore it states that death education, first, to medical professionals themselves,second,to the patients and their family,is very important,at last it also inquires into the mode of death education.

Limited Price Charge for Single Disease means that hospitals limit price for the patient who has only single disease in the diagnosis and treats process. The charge includes the process from the time when he had been diagnosed and been in hospital to the time when he had been charmed off. Limited Price Charge for Single Disease could solve many ethical problems which exist in current medicine realm, so it means too much in Medical Ethics, and it gives Hospital Administration and Health Care Administration new inspiration.

Objective To observe clinical efficacy of brinzolamide on mechanical contusion ocular trauma . Methods 50 patients(57 eyes) of mechanical contusion ocular trauma were selected and divided into observation group and control group randomly and evenly ( 29 eyes in the observe group ,28 eyes in the control group ) .On the basis of mechanical contusion ocular trauma basic treatment for all the patients , the observing group was added brinzolamide ophthalmic suspension .Their vision , intraocular pressure and ERG were observed .Results The vision of patients in the observing group was obviously better than that in the control group (χ2 =4.49,P<0.05).Intraocular pressure in the observing group (14.88 ±0.83)mmHg was obviously lower than that in the control group (19.64 ± 2.30)mmHg(P<0.05).Sum of a-wave amplitude and sum of b-wave amplitude after treatment were better than those before treatment ,and those in the observing group were higher than theose in the control group ( observation group:ta =0.44,tb =0.24;the control group:[ ta =1.03,tb =0.32;between two grous:ta =3.35,tb =2.37,P<0.05 ) ] .Conclusion Using Brinzolamide ophthalmic suspension to treat mechanical contusion ocular trauma preven -tively can obviously improve patients′vision, control their intraocular pressure and promote the recovery of retinal function.It has positive clinical effect .

BACKGROUND: The abnormality of the function of arcuate nucleus may be an important factor of obesity. It has been known that the mechanisms of acupuncture in treating obesity are related to nervous and neurohumoral regulation. What is the regulating effect of acupuncture on the function of arcuate nucleus?OBJECTIVE: To study the effects of acupuncture on the function of arcuate nucleus of obese rats, and further investigate central nervous functional mechanism of reducing weight by acupuncture.DESIGN: Randomized controlled study based on the experimental animals.SETTING: Acupuncture institute in second clinical medical college of a university of traditional Chinese medicine, and a population management college.MATERIALS: This experiment was carried out in the Acupuncture Institute of Second Clinical Medical College, Nanjing University of Traditional Chinese Medicine between April and October 2002. One-month old male SD rats just in ablactation were selected.METHODS: Rats fed with ordinary wholesome rat-feed were in the normal group. The successfully established experimental obese rats models were randomly divided as control group and acupuncture group with 12 rats in each group. Rats in the acupuncture group were given acupuncture treatment for 14 days, and rats in the normal and control groups were put into rat fixation-machine for 15 minutes every day, lasting for 14 days. Body mass, Lee' s index, body lipid, level of central and peripheral leptin and insulin(INS) as well as the frequency of spontaneous discharge of nerve cell in the arcuate nucleus(ARC) of hypothalamus in obese rats were observed with nervous electrophysiological and nervous biochemical technology before and after acupuncture.MAIN OUTCOME MEASURES: ① Effect of acupuncture on obesity index, fat contents of pericardium, kidney and epididymis of experimental obese rats. ② Effect of acupuncture on the frequency of spontaneous discharge of ARC nerve cell of hypothalamus in obese rats. ③ Effect of acupuncture on the contents of hypothalamic and serum leptin and INS of rats in each groups. ④ Correlation of the frequency of spontaneous discharge of ARC nerve cell of hypothalamus with the level of hypothalamic leptin and INS.RESULTS: The body mass[(517.74±29.35) g], Lee' s index (319.85 ± 3.96) and body fat content of obesity rats [ (13.88 ± 1.32) g] were all significantly higher than those in the normal rats, the differences were significant(P ＜ 0.01); the frequency of spontaneous discharge of nerve cell in ARC of hypothalamus in obese rats [ (3.12 ± 1.92) Hz] were all markedly lower than those of the normal rats[ (8.99 ± 2.71 ) Hz], the differences were significant (P ＜ 0.01 ); the frequency of spontaneous discharge of nerve cell in ARC was negatively correlated with body mass, Lee' s index and body lipid( r = -0. 592, -0. 672, -0. 521 ) . Acupuncture significantly increased the frequency of spontaneous discharge of nerve cell in ARC of hypothalamus in obese rats [(9.75 ±2.02) Hz] as compared with the control group, the differences were significant( P ＜ 0. 01 ).CONCLUSION: The good regulating effect of acupuncture on the function of arcuate nucleus of hypothalamus might be one of mechanisms in the antiobesity of acupuncture.

Objective To investigate the genotypes of host killing genes and their single nucleotide polymorphisms (SNPs). Methods Three hundred and twenty strains of Escherichia coli that collected from the First Affiliated Hospital of Wenzhou Medical College were analyzed. The first sample ( E1 ) contains 160 strains isolated during the years from 2002 to 2003. The second sample (E2) contains 160 strains covering the years from 2008 to 2009. The plasmids of Escherichia coli were extracted by alkaline lysis method. Solexa/Illumina sequencing technology was used to sequence plasmids metagenome. Solexa Genome Analysis System and Soap programs were used to analyze gene distribution, SNPs and lineage-specific mutations. Results 11 077 768 reads were generated and 0. 045% of them can map to the reference sequences from El sample. Whereas 9 377 792 reads were generated and 0. 053% of which mapped to the reference from E2 sample. There are nine host killing genes identified in the two samples, of which hok gene is the most prevalent. A total of 29 SNP sites dispersed in five genes of the two samples. Approximately 33% of them were non-synonymous mutations. One position of A and G is the most prevalent polymorphism. Conclusion The known nine genotypes of host killing genes were all identified in plasmids of Escherichia coli in Wenzhou. hok gene showed the highest frequency. There were SNPs in five genotypes.

Objective To establish the HPLC fingerprints of Tangbikang Granules; To scientifically evaluate and effectively control the quality of Tangbikang Granules; To ensure its production stability. Methods HPLC was performed on the column of Germany Merck RP-18 endcapped (250 mm × 4.6 mm, 5 μm) with mobile phase of acetonitrile-0.1% formic acid water; column temperature was 40 ℃; flow rate was 1.0 mL/min; detection wavelength was 240 nm; volume injection was 20 μL. Fingerprint Similarity Evaluation Software (edition 2004A) of Chinese Pharmacopoeia Commission was used to evaluate the similarity of the 10 batches of Tangbikang Granules, and to analyze the correlations of 9 ingredients in Tangbikang Granules. Results Wogonoside was used as the reference peak, and the common mode for the HPLC fingerprints was set up. The similarities of the 10 batches of Tangbikang Granules were above 0.930, and altogether 25 common peaks in the chromatograms were found, of which 18 peaks were assigned to Chinese materia medica in Tangbikang Granules. Conclusion The method has good separability and is accurate and simple, which can provide references for the quality control of Tangbikang Granules.
