OBJECTIVE: To investigate the drug use involved in outpatient's prescriptions in a hospital in 2007.METHO-DS: With the International Selected Drug Use Indicators and defined daily dose as indexes,the drug use involved in a total of 5 029 outpatient's prescriptions randomly selected from a hospital were analyzed statistically based on Excel sheet.RESULTS: Of the total 5 029 outpatient prescriptions,60.83% paid the expenses at one's own expense,and the average age of the patiens were 46.9 years.The average number of drugs prescribed for patient's each visit was 2.63 kinds,and the percentages of antibacterial agents,ampuls,and prescriptions of drugs prescribed in generic names were 21.79%,10.44%,and 50.47%,respectively.Quinolones,cephalosporins and macrocyclic lactones ranked at the first three places in DDDs and consumption sum.The drug utilization indexes of cephalosporins and penicillins were on the high side.23.72% of antibacterial agents used in combination and 76.28% alone,20.07% in bigeminy.The antibacterial agents used in trigeminy or more than 3 kinds in combination were all for antiuberculotic treatment.Physician's signature rate after prescription revision was 60.19%,and the rate of prescriptions in which medicines for oral administration or for external use were prescribed alone was 32.88%.CONCLUSION: The drug use for the outpatients in the hospital is rational on the whole,but measures should be taken to tighten control on the drug use by strenthening physicians' consiousness on rational drug use so as to reduce the incidence of irrational drug use.

Objective To investigate the clinical and pathogenic features and other related factors of hospital-acquired bloodstream infections (HABSI) in geriatric wards,in order to provide the scientific basis for clinical diagnosis and therapy.Methods Clinical characteristics and other related factors of HABSI in patients admitted to the Department of Geriatrics of our hospital from June 2010 to October 2015 were retrospectively analyzed.Results Of the 64 elderly patients with HABSI,malignant tumor (39.1％) and type 2 diabetes mellitus (32.8％) were among the main disorders for their admission to the hospital.There were 53 cases of primary bloodstream infections and 11 cases of secondary bloodstream infections,accounting for 82.8％ and 17.2％,respectively.Primary infections involved mostly the respiratory,urinary and hepatobiliary systems.13 patients died,giving a fatality rate of 20.3％.Multiple logistic regression analysis showed that the retention time of central venous catheters or implantable venous access ports was ≥ 7 days (OR =49.51) and the duration of proton pump inhibitor administration was ≥3 days (OR=13.63),and these were independent risk factors for HABSI in elderly patients.A total of 66 strains of pathogenic bacteria were detected from the 64 patients.The most common G+ type was coagulase negative staphylococcus (18.2 ％) and the most common G-bacteria were Escherichia coli (18.2％) and Klebsiella pneumonia (15.2％),with the latter two making up 54.5％ of the extended-spectrum β-lactamase (ESBL)-producing strains.Conclusions HABSI can seriously affect the prognosis of elderly patients.Reduction in invasive procedures,active prevention and treatment of tumors,improvement of the internal environment and protection of vital organ functions are the main measures to reduce the bloodstream infection rate in geriatric wards.

OBJECTIVE:To investigate the study of traditional Chinese medicine (TCM) in the treatment of chloasma,and to provide reference for clinical treatment and study of chloasma. METHODS:Retrieved from CBM,Wanfang database,CNKI and VIP,usingchloasmaas subject,the literatures of TCM therapy were collected during Jan. 2003-Dec. 2012. Bibliometric meth-od was adopted to analyze included literatures statistically in respects of publication amount,periodicals,research institution,litera-ture types,citing references,other periodicals citatien times,fund support,distribution of provinces and cities. RESULTS:During 2005-2012,the amount of the literatures increased slowly. Among top 10 journals in the list of publication amount,only Chinese Journal of Aesthetic Medicine was not TCM journal and took up the first place. Among top 7 research institutions in the list of publi-cation amount,TCM colleges took up predominant place,followed by TCM hospitals. The types of the literatures were mainly case report,contrastive study before and after treatment,group-divided control study;the amount of group-divided control studies increased gradually year by year. The references cited were mainly English literatures. There were 82 literatures which were cited by other periodicals more than 10 times;the highest time of other periodical citation per literature was 47 times;only 11 literatures were supported by fund. The institutions of literatures authors were distributed in 32 provinces,cities and autonomous regions of China,mainly in the eastern coastal areas. CONCLUSIONS:More and more attention has being paid to TCM therapy for chloas-ma,but the scope and depth of the studies were inadequate. From the point of view of modern medicine,we can explore the patho-logical TCM mechanism and the treatment method of shortening the course of disease.

Whether three genes [?-aminolevulinic acid dehydratase (ALAD) gene, Vitamin D receptor (VDR) gene and hemochromatosis gene] can make certain individuals more vulnerable to lead are discussed. Polymorphisms of ALAD gene have been associated with the accumulation and distribution of lead in the blood, bone and internal organs in humans and animals. VDR gene has been implicated in the control of calcitriol levels in serum, which normally regulates calcium absorption and can in turn affect lead levels. Hemochromatosis gene, associated with a disease that leads to excessive iron accumulation, may also influence the absorption of lead.

Objective To assess the removal efficiency of bacteria by water purifiers using different purifying materials. Methods The bacterial removal effectiveness of 7 types of commercially available water purifiers was tested using the National Standard Methods. Results Apart from one type using a single activated-carbon filtering material, the bacteria removal effectiveness of the other 6 types of water purifiers met the requirements of water purification device according to the rated treated-water-capacity conditions. Conclusion The removal efficiency of bacteria by water purifiers made from different filtering materials was different. Bacteria elimination effectiveness of a single-filtering material was lower and it is inversely proportional to its water-treating capacity. Water purifiers using multiple-purifying materials gave better removal efficiency of bacteria.

Objective　To investigate the pattern of human neutrophil degranulation mediated by Fc alpha receptors. Methods　IgA immune complexes (IgA IC) and specific monoclonal antibody were used to stimulate neutrophil degranulation. Lactoferrin released by stimulated neutrophils was quantitatively determined. Results　Monoclonal antibody and IgA IC could both induce neutrophil lactoferrin release. However, monoclonal antibody induced rapid and strong degranulation whilst the effect of IgA IC was much weaker. Conclusion　The pattern of neutrophil degranulation induced by IgA IC and monoclonal antibody is different.

Objective To evaluate the clinical value of multi-slice spiral CT in diagnosing tracheobronchial foreign bodies in chil-dren.Methods 139 patients with airway foreign body confirmed by bronchoscopy were examined with 128-slice spiral CT,and then the CT data was reconstructed by using multiple-planar reconstruction(MPR),curved planar reconstruction (CPR),volume render-ing(VR),minimum intensity projection(MinIP)and virtual endoscopy (VE).The CT results were compared with bronchofibersco-py findings.Results Among the 139 cases,the foreign bodies located at trachea in 13 cases,right bronchia in 75 cases,left bronchia in 48 cases,and bilateral bronchia in 3 cases.137 cases (98.6%)were correctly diagnosed,and 2 cases (1.4%)were missed on CT.Although the difference of the results at trachea and right main stem bronchus was statistically significant (P <0.05),the over-all results was not significant difference between CT and bronchoscopy examination (P =0.340).Associated findings included em-physema in 74 cases,pneumonia in 48 cases,atelectasis in 22 cases,mediastinal displacement in 57 cases,lung interstitial emphyse-ma in 4 cases,pneumomediastinum and pneumoderma in 4 cases,bronchiectasis in 2 cases,and pleural effusion in 4 cases.Conclu-sion MSCT and its postprocessing techniques can accurately and intuitively display the tracheobronchial foreign body and complica-tions,which has important value for clinical application.

Objective To study the effect of continuous renal replacement therapy(CRRT) in preventing myonephropathic metabolic syndrome(MNMS) after operation of acute arterial occlusion. Methods Twenty-four patients with acute arterial occlusion were divided randomly into 2 groups: CRRT group(n=11) and control group(n=13).The patients were treated with embolectomy or revascularization.In control group,we used conventional therapy such as anti-inflammation,expansion of blood capacity,anticoagulation,and correcting acidosis and electrolyte disorder.In CRRT group,patients were treated by continuous veno-venous hemofiltration(CVVH) with 6 h during operation and 24 h after operation. Results In control group,24 h after operation,the serum potassium,blood urea nitrogen(BUN),serum creatinine(SCr),and myoglobin(Mb) were significantly increased(P

Our study demonstrated that ARS cells can be induced to differentiate into macrophage-like cells with changes in phenotype, nonspecific esterase activity and phagocytic function by adding ginsenosides in short-term cultures. Synthesis of DNA, mitosis and the growth of the culture cells transplanted in mouse are also inhibited in this condition. The size of cells, nuclei and nucleoli, as well as nuclear-cytoplasmic ratio of ginsenosides treated cells are diminished significantly. Microvilli of these cells are reduced in number with formation of. ruffles on the cell surface. Mitochondria are increased, their size and distribution become regular. The fact that numerous small cells, induced by ginsenosides exhibit the most conspicuous alteration mentioned above along with marked phagocytic activity indicates that they are highly differentiated macrophage-like cells. Whether the inhibition of cell growth and induction of differentiation by ginsenosides is caused through its action on the molecules regulating the gene expression of cell growth and differentiation needs further study.
