OBJECTIVE: To detect whether there is mixing of norfloxacin in loperamide hydrochloride capsules by UPLC-MS. METHODS: The separation of norfloxacin was performed on C18 column with column temperature set at 35 ℃, and the mobile phase was composed of acetronitrile and 0.1% formic acid (gradient elution) with a flow rate of 0.3 mL?min-1. The sample size was 10 ?L. ESI source was applied with capillary tube tension at 3.0 kV and ion source temperature at 110 ℃, and scan mode was multiple reaction monitor. RESULTS: It has been proved that there was norfloxacin in 2 of the total 5 batches of samples based on the data of retention time of RP-HPLC including ultraviolet spectra, the quasi-molecular ion and the second order mass spectra split fragments. CONCLUSION: The method is highly selective and sensitive, and can be used to detect whether norfloxacin has been illegally added into loperamide hydrochloride capsules.

OBJECTIVE To investigate the expiry date of sterile articles packed by 4 different materials and preserved in different conditions after pressure steam sterilizing. METHODS The bacteria growth of the materials sterilized by pressure steam sterilizing method and stored in the supply department,treatment room,dressing room,nursing cabinet and ambulance vehicle was observed. RESULTS The axenic periods of the sterile materials in the supply department preserved by methods A,B,C,D were 14 days,14 days,7 months and 8 months,respectively in summer;while the sterile periods of the materials in the treatment room,dressing room,nursing cabinet and ambulance vehicle preserved by methods A,B,C,D were 11 days,11days,6 months and 7 months,respectively. CONCLUSIONS Management of expiry date of sterile materials is an important measure to guarantee safe use of sterile materials and prevent against nosocomial infection.

AIM: To establish a quick,accurate,sensitive method for analysis of theophylline,prednisone acetate and dexamethasone acetate illegally added into traditional Chinese medicinal preparation for antitussive and antiasthmastics by UPLC-MS. METHODS: The UPLC-MS/MS method was used.Electrospay ionization(ESI) source was applied and operated in the positive and negative ion mode.Theophylline,prednisone acetate and dexamethasone acetate illegally added into traditional Chinese medicinal preparations were identified. RESULTS: Both theophylline and prednisone acetate were found in formulations. CONCLUSION: The method is selective and sensitive and can be used to detect the theophylline,prednisone acetate and dexamethasone acetate illegally added into traditional Chinese medicinal preparations.

The paper is to report the establishment of a method of characteristic figure analysis for the quality control of Panacis Quinquefolii Radix. Application of HPLC-UV-ELSD techniques was connected in series and applied. The separation was carried out on the Agilent Extend-C18 (250 mm x 4.6 mm, 5 microm) column. The mobile phase consisted of water and acetonitrile with gradient elution. The flow rate was 1.0 mL x min(-1) and the wavelength of measurement was 203 nm. The temperature of drift tube was maintained at 106.5 degrees C and the flow rate of air was set at 2.9 L x min(-1). Twenty batches of the Panacis Quinquefolii Radix were determined. Hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied to study on the HPLC characteristic figure and chemical pattern recognition. The HPLC-UV and HPLC-ELSD characteristic figure of Panacis Quinquefolii Radix was developed, the ginsenosides Rg1, Re, Rb1, Rc, Rb2, Rb3, Rd and the pseudoginsenoside F11 were identified. This method is accurate and reliable, and it can be used to control the quality of the Panacis Quinquefolii Radix.

OBJECTIVE：To introduce pharmacogenomics and its applications in establishing clinical pharmacotherapeutic schemes.METHODS：Based on the analysis of the related literatures,the development and contents of pharmacogenomics and their relationship with individualized medication were summarized.RESULTS：Pharmacogenomics studies the association between gene polymorphisms and the variance of drug effects.CONCLUSION：Pharmacogenomics provides a theoretical basis for medication with safety,effectiveness and rationality.

Objective To observe the effect of Fugong Decoction(Decoction for Uterine Restroation) as assistant therapy of medicinal abortion for early pregnancy.Methods The 134 early pregnancy women who were volunteers of medicinal abortion were randomized into a treatment group and a control group with 67 cases in each.The control group was treated with Mifepristone and Misoprostol while the treatment group treated with Fugong Decoction based on these drugs.Totally they were treated for 7 days.The abortion effect,volume of vaginal bleeding,bleeding time,and time of urine human chorionic gonadotrophin(HCG) changed to negative were observed.Results In the treatment group,the time of discharge of gestational sac,volume of vaginal bleeding,bleeding time,time of urine HCG changed to negative,and abortion effect were all better than those of the control group,with significant difference(P

Objective To study the cognitive disorder in acute brain infarction. MethodCognition was meaured by P300 Peak Latency and The MMSE Scale for 32 patients with acute brain infarction. Results There are significant difference in P300 Peak Latency and The MMSE Scale scores between the patients and controls. ConclusionP300 Peak Latency could indicate the cognitive disorder in patients with acute brain infarction.

Objective: To investigate the cellular mechanism of renal proximal tubular epithelial cell(PTEC) injury induced by aristolochic acid Ⅰ (AA Ⅰ) and aristololactam Ⅰ (AL Ⅰ). Methods:Human PTEC cell line HK 2 was used as the subject. Cell apoptosis was evaluated by using FACS. Fibronectin (FN) and TGF ?1 levels were assayed in the supernatant from cultured HK 2 cells by ELISA. In the blocking study, anti TGF ?1 neutralizing antibody was used as an antagonist. The changes of FN level and apoptosis were compared. Results: After stimulation by 2.5 mg/L AA Ⅰ, HK 2 cells secreted TGF ?1 at hour 12 and FN at hour 36. HK 2 cell apoptosis was detected at hour 48. Anti TGF ?1 neutralizing antibody (5 mg/L) could suppress AA Ⅰ induced apoptosis by 63.7% ( P

AIM To explore the mercury accumulation in KM mice after being given Zuotai at different doses and time.METHODS KM mice were randomly divided into blank group,Zuotai low-,middle-and high-dose (6.07,60.70 and 606.97 mg/kg,42 d;606.97 mg/kg,14 d) groups.The mercury contents in brain (olfactory bulb,cortex,hippocampus,hypothalamus,brain stem,cerebellum),heart,lung,kidney,liver,spleen,serum,muscle of mice were measured after administration.RESULTS Compared with the blank group,Zuotai at low-dose significantly increased the mercury contents in hippocampus,cerebellum,lung,kidney,liver and serum of mice after 42-day treatment;Zuotai at middle-dose markedly increased the mercury contents in olfactory bulb,cortex,hippocampus,brain stem,cerebellum,heart,lung,kidney,liver,spleen and serum of mice after 42-day treatment;the mice treated with high-dose of Zuotai for 42,14 days significantly increased the mercury contents in olfactory bulb,cortex,hippocampus,hypothalamus,brain stem,cerebellum,heart,lung,kidney,liver,spleen,muscle and serum.CONCLUSION Mercury can be accumulated in different tissues of mice after intragastric administration of Zuotai in a dose-and time-dependent manner,which suggests that Zuotai and its compound preparations should not be used in high-dose and long-term.

The main academic thought of Hunan acupuncture-massotherapy academic school is five meridian compatibility, which achieves the purpose of regulating viscera through needling meridians and treating viscera.Five meridian compatibility combines five-element generation and inhibition theory and meridian-viscera relationship theory andtreats peptic ulcer by needling five meridians, regulating five zang organs and using five elements theory to provide a new idea for clinical acupuncture treatment of splenogastric diseases.
