Leptin is type I cytokine detected recently.It takes part in physiological action such as energy balance, fat storage and process of metabolism,reproduction and hemopoiesis in vivo.Leptin may be an important role between adipose tissue and genital system.Lack or excessive of leptin is related to infertility in some diseases involving in nutritional status. Leptin takes part in female infertility pathogenesis in hypothalamus pituitary gland gonad axia and other respects.

OBJECTIVE:To investigate the characteristics of adverse drug reactions (ADR) caused by quinolones in our hospital and to promote their rational use in clinic. METHODS: By a retrospective review,a total of 199 quinolones-induced ADR cases collected from May 2004 to December 2007 in our hospital were analyzed statistically in respect of patients' gender and age,drug species involved,past ADR history,route of administration,clinic manifestations,etc. RESULTS: A total of 9 kinds of quinolones involved in the 199 ADR cases,of which,118 cases were induced by levofloxacin,16.1% had past ADR history,93.5% of the ADR cases were induced via intravenous drip,and most common presentations of the ADR were lesions of skin and its appendants as well as digestive system. There were 7 serious ADR cases. CONCLUSION: The indications of quinolones should be controlled strictly,which should be preferably administered orally and monitoring of its administration should be emphasized in clinical practice to decrease and avoid the occurrence of ADR.

The compounded prescription of Chinese crude drug is a key problem in the study of traditional Chinese medicine.A new research field that focuses on the group of effective fractions of Chinese crude drugs becomes more important as the result of combination of the theorem of traditional Chinese medicine and techniques of modern medicine.Up to date,the researches on this field are preliminary,remaining a lot of subjects to be explored.

OBJECTIVE:To assess the stability of the quality control of FPIA for monitoring of CsA and MEIA for monitoring of FK506.METHODS:The quality control on the blood samples of patients receiving therapeutic drug monitoring of CsA and FK506 from June to August in 2007 were subjected to a continual assessment and analysis to investigate the stability and accuracy of the quality control.RESULTS:The mean recoveries of the low,middle and high concentrations of CsA and FK506 were 93.14%～97.65% and 97.70%～103.09% respectively,with RSD at 4.41%～5.37% and 10.44%～14.23% respectively,which accorded with the requirement for biological sample determination stated in the Chinese Pharmacopoeia.CONCLUSION:The methods of FPIA for monitoring of CsA and MEIA for monitoring of FK506 were accurate,and worth to be applied in clinical to guide individualized medication.

OBJECTIVE:To analyze the distribution of the common pathogenic bacteria and drug resistance in urinary tract infection for clinical reference of rational use of antibacterials. METHODS:The medical records of patients hospitalized in urinary surgery in our hospital from Jan. to Oct. in 2008 were retrospectively collected for analyses of the results of mid-stream urine culture and antibiotic resistance,meanwhile,the current utilization of antibacterials in urinary surgery was analyzed. RESULTS:Gram negative bacilli were the major pathogenic bacteria in urinary tract infection(61.82%),of which,escherichia coli represented 58.82%,and the resistant rates of the gram negative bacilli to imipenem,amikacin,cefoperazone/sulbactam and piperacillin/tazobactam were 8.82%,8.82%,11.76% and 11.76%,respectively. CONCLUSION:The antibiotics should be used rationally according to the result of susceptibility test in treating patients with urinary tract infection.

OBJECTIVE: To evaluate the extent of endolymphatic hydrops as shown by three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D FLAIR MRI) performed 24 hours after bilateral intratympanic gadolinium administration and discuss the positive rate of endolymphatic hydrops in vestibule and cochlea. METHOD: Twenty-four hours after bilateral intra-tympanic 8 times diluted gadolinium administration, three-dimensional fluid-attenuated inversion recovery MRI, using a three-Tesla unit, was performed in 48 patients, and then assessed the extent of endolymphatic hydrops in the MRI images. RESULT: Forty-eight patients showed different levels of enhancement of perilymth in the inner ear. In these patients, obvious signs of endolymphatic hydrops were visualized in vestibule,including 8 slight hydrops, 17 mild hydrops and 23 severe hydrops with a diagnostic rate of 83.3%. There were almost no complications in all 48 patients after bilateral intra-tympanic injection except short vertigo in some of them. CONCLUSION 3D FLAIR MRI resonance imaging has a high positive diagnostic rate in assessing endolymphatic hydrops of Ménière's disease and provides direct imaging evidence for diagnosing Ménière's disease.

OBJECTIVE:To develop a new electronic medication record web page and facilitate its remote data management.METHODS:With the aid of the Windows 2000 platform,the new electronic medication record web page was set up by using Visual Studio.Net,and its remote data management was achieved by using SQL Server.RESULTS:With the new mode of electronic medication record web page,detailed and accurate clinical data become available for clinical pharmacists and a remote data management has come off,furthermore,it is easy to operate.CONCLUSION:As a new mode of electronic medication record,it deserves to be popularized in clinical pharmacists.

Objective:To re-establish the quality control standard for Weiling granules. Methods:The 4 chief herbs in the prepa-ration, radices paeoniae alba, licorice, rhizoma corydalis and hawthorn were identified by TLC qualitatively. The content of paeoniflor-in in radices paeoniae alba was determined by HPLC. The separation was performed on an Agilent XDB-C18 (250 mm × 4. 6 mm, 5μm)coulme with mobile phase consisting of acetonitrile-0. 1% phosphoric acid solution (10:90). The detection wavelength was 230 nm and the flow rate was 1. 0 ml·min-1 . Results:The spots in TLC were clear without any interference. The linear range for paeoni-florin was 0. 151-1. 212 μg(r=0. 999 9,n=5). The average recovery was 99. 63% and RSD was 2. 01%(n=9). Conclusion:The method is simple and accurate with high reproducibility, which can be used for the quality control of Weiling granules.
