The present paper reports the determination of the contents of Cu,Zn,Mn,Fe,Cr in three kinds of teas of Yunnan and their released rates with Flame AAS.Released rates of Cu, Zn,Mn,Fe in Black Tea and Green Tea are higher than those of Tuo Tea,while relesed rate of Cr is similar to that of Tuo Tea.

The determination of the inorganic elements in Amomum villosum lour with AAS and AES is reported in the paper. We have also measured the recovery rate(%) and precision (CV%) of Mn, Fe, Zn and Cu, which are 81-101 and 1.7-2.7 respectively.

OBJECTIVE:To establish a HPLC method for the determination of gentamycin sulfate C component in medicinal albumin gel. METHODS: Samples was separated on Agilent ZORBAX Eclipse XDB-C8 at a column temperature of 26℃. The mobile phase was methanol-acetic acid-water (70∶5∶25, added with 0.02mol?L-1 sodium heptanesulfonate solution) for gradient elution at a flow rate of 1.0mL?min-1. The detection wavelength was set at 330nm. RESULTS: Baseline separation of gentamycin sulfate C component in medicinal albumin gel was achieved. The linear range of gentamycin sulfate C component was 0.26?g～6.50?g and its average recovery rate was 90.0%, RSD=0.43%, the lowest limit of detection was 0.368ng. CONCLUSION: The method was proved to be simple, accurate and reliable, and suitable for the content determination of gentamycin sulfate C component in related preparations.

Objective To investigate the intentions of pension mode of the aged in the unban and rural of Xi' an,and analyze the possible influential factors in old persons' choices of pension modes.Methods The purposive sampling method was used to survey the old persons about their pension intentions by questionnaire,and the collected information underwent statistical analysis.Results Among 317 old persons aged from 60to 91 years old investigated in the study,145 cases were from urban and 172 from rural area.Most old people intended to choose self-pension mode,family pension mode and community pension mode.Only few people chose institution pension mode.Their favorite pension mode was family pension mode,and institution pension mode was the last one to choose for old people.Community pension mode should be developed mostly in their opinion,and self-pension mode must be reduced.Some essential variables had significant influence on their choices of pension models,such as living in urban or rural,occupation,age,marriage,the incomes per month,family support,habitancy and so on.The result of logistic analysis showed that some other variables had no obvious influence on their pension intentions.Conclusions Old people in Xi'an prefer family pension mode mostly.Community pension mode is the one which has a good developing prospect.Social pension mode need to be intensified.

OBJECTIVE:To identify different origin of Scutellaria amoena CH Wright and Scutellaria baicalensis Georgi indexed in China Pharmacopeia by HPLC fingerprints.METHODS:RP-HPLC method was adopted in which the samples were separated on Zorbax SB-C18(250mm?4.6mm,5?m)column at a column temperature of 30℃.The gradient elution was performed on the mobile phase which consisted of acetonitrile(contairing 1.0% methanoic acid)-water(containing 1.0% methanoic acid)at a flow rate of 1.0mL?min-1.The detection wavelength was set at 274nm.RESULTS:The fingerprints of Scutellaria amoena CH Wright that from different places were of great resemblance,so were the fingerprints between Scutellaria baicalensis Georgi that from different places,but the fingerprints between Scutellaria amoena CH Wright and Scutellaria baicalensis Georgi were of significant difference,with resemblance of only 0.859.CONCLUSION:The RP-HPLC fingerprint serves as basis for the further study of the quality criteria of Scutellaria amoena CH Wright and Scutellaria baicalensis Georgi.

Two hundred and twenty five children aged 4-12 years with phimosis were treated by flexible dilatation combined with topical betamethasone cream from January 2003 to January 2015.Two hundred and eight cases (92.44％) were completely cured and penile edema and urination were returned to normal 7 d after a single operation;while,17 children received 2-3 additional flexible expansion.During follow-up of 2-24 months,221 children achieved the cure standards with an overall cure rate of 98.22％.Flexible dilatation combined with topical betamethasone cream is effective modality for phimosis in children,with less surgical trauma and low complication rate.

Eight-year-system medical education is a kind of elite education. The object of this education model is to train medical personnel with medical doctorate. Forensic science is a highly practical medical discipline, closely related with the clinical medicine. This paper performs some explorations of the role of forensic science in 8-year-program medical education. Eight-year-program medical education should be combined with the high practicality of forensic science. For the Eight-year-program students, we should focus on cultivating their creative ability, practical ability, and sense of self-protection.

In the marketing theory, service disparity model is a simple effective tool, capable of figuring out the five clusters of reasons leading to service failure. This article applies it in the community health service domain. Through the efforts of healing the five gaps in service delivery, including Consumer expectation-management perception gap, Management perception-service quality specification, Service quality specifications-service delivery gap Consumer expectation-management perception gap and Service delivery-external communications gap, we hope to improve the community health service quality radically.

AIM:To study the chemical constituents of Lysimachia clethroide Duby. METHODS:Chromatographic techniques,including MS and NMR,were used to isolate and purify the constituents based on column chromatography separation on silica gel,Sephadex LH-20 and Semipreparative RP-HPLC. RESULTS:Eleven flavonoids were obtained and elucidated as: kaempferol (1),kaempferol 3-O-?-D-glucopyranoside (2),kaempferol 3-O-?-D-galactoside (3),kaempferol 3-O-?-D-(6″-p-coumaroyl)-glucopyranoside (4),quercetin (5),Isorhamnetin (6) ,quercetin 3-O-?-D-galactoside (7),quercetin 3′-methoxy-3-O-?-D-galactoside (8),quercetin 3-O-?-D-(6″-p-coumaroyl)-galactoside (9),4′-methoxy-5,6-dihydroxyisoflavone-7-O-?-D-glucopyranoside (10),7-O-glucosyl liquiritigenin (11). CONCLUSION: Compounds 3,6 were isolated from this plant and compounds 8-11 were isolated from this genus for the first time.

Objective To study the reason and preventive measures of inconformity of the extraction appeared in the process of transfusion blood specimens with the patient's blood type.Methods The reasons of transfusion errors why extracting required blood type was not consistent with the patient's blood type examplesa in Zhengzhou transfusion of hospital from 2008 to 2012 were retrospectively analyzed.Results The experimental results showed that blood specimen inconformity was 49.60%,the error rate of blood extraction and blood infusion was 31.20%,infusion error only was 15.20%,blood type change after stem cell transfusion was 4.00%.Reasons of blood type change after stem cell transplantation to extract blood samples mainly included the blood center or blood did not accord with logo type blood stations provided (16.13%),blood use application form to fill in error(20.97%),check the wrong blood type (6.45%),blood samples taken(29.03%),the blood sample tag(27.42%).Conclusion In order to ensure the safety for clinical use must adopt measures to prevent resolutely put an end to a blood transfusion errors.
