OBJECTIVE To learn the situation of cephalosporins used in our hospital,and offer the scientific guidline base for their clinical use.METHODS Statistics methods were used to analyze dosage,sales volume and DDDS of cephalosporins during 2003-2007.RESULTS The usage of the first generation cephalosporins was reduced year by year,but the third generation of compoands cephalosporins and their oxef cephalosporins occupied the main places.The DDDs of cefoperazone/tazobactam usage ranked second for three years(2005-2007),and at the same period their DDDs consumption got top.CONCLUSIONS The situation of the usage of cephalosporins in our hospital is reasonable basically,but more attention should be payed to the usage of the third cephalosporins and their compounds and oxefs.

0.05). Conclusion Tei index may be useful, convenient and reliable in fetal cardiac function assessment.

OBJECTIVE:To study the status quo of drug use in the elder hospitalized patients(over 65 years old)and their demand for drugs.METHODS:The drugs used in the 12 614 elder hospitalized patients(over 65 years old)between July,2005 and June,2006 were statistically analyzed.RESULTS:The drugs used in elder hospitalized patients totaled 1 347 kinds,which were mainly administered orally or by injection.The consumption sum of injection accounted for 85.81% of the total.The most common diseases in the elder hospitalized patients were tumor diseases,cardiovascular and cerebrovascular diseases,and which were more often seen in males than in females.CONCLUSION:The drugs used for the elder hospitalized patients were many in kinds.The expenses of injection showed a highest proportion in the total drug costs.Cerebrovascular and cardiovascular diseases and tumor diseases are main diseases that threat health of aged people.

Objective To investigate the effect of probiotics preconditioning on intestinal mucosal barrier function in a rat model of cardiopulmonary bypass (CPB) . Methods Twenty-four adult male SD rats weighing 350-450 g were randomly divided into 3 groups ( n = 8 each) : group Ⅰ sham operation ( group S); group Ⅱ CPB and group Ⅲ probiotics + CPB. CPB was established between left carotid artery and right jugular vein and maintained for 60 min. Croup Ⅲ received intragastric instillation of probiotics 2 ml once a day for 7 consecutive days before CPB. Blood samples were collected at 2 h after CPB was terminated for determination of plasma D-lactate, TNF-and IL-6 concentrations and diamine oxidase (DAO) activity. Venous blood was obtained from portal vein for determination of LPS concentration and cultured. Liver, pancreas, spleen, kidney and mesenteric lymphnode (MLN) specimens were obtained under sterile condition and cultured for bacterial growth. The mucous membrane of small intestine was examined with electron microscope. Results CPB significantly increased plasma DAO activity, and D-lactate, IPS, TNF-α and IL-6 concentrations and the rate of bacteria-positive culture of portal venous blood, liver, MLN, lung and kidney in group Ⅱ as compared with group S. Probiotics preconditioning significantly attenuated the above-mentioned CPB-induced changes. Microscopic examination showed that probiotics preconditioning significantly ameliorated CPB-induced damage to the epithelium of the small intestine. Conclusion Probiotics preconditioning can significantly attenuate CPB-induced inflammatory response and protect the intestinal mucosal barrier function.

Objective:To gain an insight into the immunological mechanism of tuberculosis by observing the variation of T lymphocyte subgroups in endobronchial tuberculosis(EBTB) patients.Methods:The variation of T lymphocyte subgroups was determined by flow cytometry in 23 EBTB patients and 25 physical examinees and results were compared.Results:The value of CD8 T lymphocytes was significantly lower in the EBTB patients than in healthy controls(P0.05).Conclusion:The pathogenesis of tuberculosis is associated with the changes in the immune system.CD4 and CD8 T lymphocytes play an important role in the cell-mediated immune response.

Objective To provide reference for clinical pharmacists participating in pharmacotherapy of low molecular weight heparin calium-induced thrombocytopenia.Methods Clinical pharmacists carried out pharmaceutical care for a patient with chronic cor pulmonale with acute exacerbation of chronic asthmatic bronchitis in the use of low molecular weight heparin calium,who developed progressive thrombocytopenia,and helped clinicians to manage adverse reaction and select subsequent treatment drug.Results The suggestions were adopted by clinicians.The platelets of patients gradually recovercd without thrombosis events.Condusion Participation of clinical pharmacists in the treatment of low molecular weight heparin calium induced-thrombocytopenia can effectively improve the prognosis of patients and ensure the safety in drug use.

Objective To Study the effect of efflux pump-inhibitors(EPI)-Verapamil in photodynamic therapy (PDT) using hematoporphyrin monomethylether (HMME) as photosensitizer on the cariogenic bacteria in dental plaque biofilms.Methods According to the administrator order of the verapamil and photosensitizer in PDT,streptococcus mutans,streptococcus sanguis,eosinophilic lactobacillus and actinomyces viscosus were used to establish the dental plaque biofilm model.The experiment was divided into five groups,group A was incubated with the photosensitizer and verapamil group,group B using verapamil before incubated the photosensitize,group C suing photosensitizer before incubated verapamil,group D with PDT only,group E was control group.After laser treatment,the influence of the dental plaque biofilms was observed by confocal laser scanning microscope.Results As saline-treated group is a group of normal the dental plaque biofilms.In PDT only group,compared with the saline group,red fluorescence increased significantly,the bacteria lose accumulation capacity,and were isolated and scattered in dispersed state.In PDT plus verapamil group,compared with only PDT group,green staining increased,bacterial activity increased.In group B,cells were incubated with verapamil before incubated the photosensitizer group,green staining increased significantly,red fluorescence reduced,indicating live bacteria increased,and bacteria activity was significantly increased.Conclusion PDT is an effective method in eliminating cariogenic bacteria of dental plaque biofilms.Bacterial efflux pump inhibitors can lower HMME-PDT inhibition cariogenic bacteria in dental plaque biofilm,and pre-verapamil administration could significantly inhibit the effect of PDT treatment of dental caries.
