Objective To study the different influences of Xiaobanxiatang superfines (XBTs) made of Chinese medicinal materials and traditional decoction (XBTd) on gastrin. Method The model of mice were made with cisplatin. To observe the effect of the different forms of XBT on gastrin in serum and small intestine. Results After giving medicine, XBTd and XBTs remarkably increased the gastrin in serum and small intestine (P

OBJECTIVE:To evaluate the effect of single decoction vs.mingled decoction on the content of Baicalin in Radix Scutellariae.METHOD:The separation of samples was performed on Agilent C18 column(250 mm?4.6 mm,5 ?m)with a column at room temperature.The mobile phase consisted of 0.5% formic acid-methano and 0.5% formic acid solution(55∶45)with flow rate of 1.0 mL?min-1 and detection wavelength of 274 nm.RESULTS:The linear range of Baicalin was 0.258 5～2.326 5 ?g(r=0.999 9)with an average recovery of 97.8%(RSD=1.1%,n=9).CONCLUSION:The content of Baicalin in Radix Scutellariae decocted alone is higher than in the mixture of all the single decoctions,and significantly higher than in Radix Scutellariae decocted by mingled decoction,all showing significant differences.

OBJECTIVE To study the pathogen distribution and drug-resistance status of Gram-negative bacillary pneumonia and draft preventive and control measures.METHODS The sputum and lower respiratory tract secretion of 268 patients with Gram-negative bacillary pneumonia were cultured to detect pathogens.Susceptibility test was performed.Then the results were analyzed retrospectively.RESULTS Detection rates of Pseudomonas aeruginosa rated the top one,reaching 29.9%;then was Klebsiella pneumoniae,accounted for 19.4%;Acinetobacter baumannii ranked the third,accounted for 15.3%.The drug-resistance supervision manifested that the resistant rate of Gram-negative bacteria to ampicillin was the highest,reached 81.6-94.7%;that to imipenem was the lowest,reached 0-2.5%.And extensive-spectrum beta-lactamases(ESBLs) occurred with 30.0%.CONCLUSIONS The higher drug-resistance to common antibiotics occurs in Gram-negative bacillary pneumonia in our hospital.Clinical microbiology department should monitor pathogens well to provide the evidence for infection controlling.

OBJECTIVE To formulate the effective measurement to prevent and control nosocomial infection in blood transfusion department.METHODS The hidden danger of nosocomial infection in our hospital was investigated to formulate the practicable strategy of precaution and control.RESULTS Management status in blood transfusion department occurred several administration shortages such as unreasonable overall arrangement,flaw regulatory regime,weak precaution consciousness,nonstandardized contamination zonation,deficient management of medical garbage disposal,etc.CONCLUSIONS Executing strictly laws and regulations,establishing relevant rules and carrying on standardized administration are essential for prevention and control of nosocomial infections in blood transfusion department and for assurance of biosafety.

OBJECTIVE To investigate probationer nurses' knowledge about nosocomial infection (NI) and clean operating-room. METHODS Survey among probationer nurses was performed by self-designed questionnaires. RESULTS 47% probationer nurses thought it very necessary to strength knowledge about NI before probation. The scores of clean operating-room knowledge was lower than that nosocomial infection (NI); The cognition rate among high educated probationer nurses were higher than low educated,P

OBJECTIVE To compare the cleaning efficacy of manual cleaning with ultrasonic cleaning on laparoscope and choose the best way to clean laparoscope under present condition.METHODS The laparoscopes were collected from each department based on the weekly usages.The efficacy of the cleaning way was the focus.The cleaniness of the laparoscopes were inspected with naked eyes.RESULTS The cleaning effect of the ultrasonic cleaning method was better than the manual cleaning method for the laparoscope.It would help for the cleaning effect to remove the air bubble in the laparoscope pipeline.CONCLUSIONS Ultrasonic cleaning method plus removing the air bubble in the laparoscope pipeline could guarantee the cleaning quality for the laparoscope.

The recent advances in research of oxygen free radicals and its relation to Parkinsons disease (PD) was reviewed. Though there is no exact knowledge of the causes of PD, the role of oxidative stress in the etiology of PD has been focused on. Investigations on patients have shown that PD is under a status of oxidative stress. The biochemical features of dopaminergic neurons in the pathologic site of PD implicate the close relation of oxygen free radicals' generation with the pathogenesis of PD. Besides the oxidative stress hypothesis, other proposed hypotheses are also direct or indirect related to oxidative stress.

Alzheimers disease (AD) is a progressively and retrogressively neurodegenerative disorder characterized by two hallmarks: senile plaques (SP) and neurofibrillary tangles (NFTs). The studies of animal models, which are crucial to the further study of AD, will promote the understanding of the etiology, mechanisms and medicine screening. Although the animal models such as experimental injury, normal aging and compound types could represent the cognitive deficit, they lack the essential neuropathological characteristics of AD. Senescence accelerated mouse / prone 8 is one of relatively practical and stable models. The most enchanting focus of AD models is transgenic mice that provide new carriers for the research of pathogenic forms of specific genes and metabolites thereof in vivo. As therapies of AD evolve from symptomatic treatment to causative treatment,so must the animal models of AD.

Objective To understand the air quality of the hospital clean operating rooms and the effecting factors in Guangzhou city, China. Methods In Jan-Oct, 2006, 18 clean operating rooms in five large scale hospitals were chosen and the related indexes such as airborne particles and airborne bacterial concentration were tested according to GB/T16292-1996 Test Method for Airborne Particles in Clean Room of Pharmaceuticalindustry, GB/T16293-1996 Test Method for Airborne Microbe in Clean Room of Pharmaceuticalindustry, GB/T 18204-2000 Standard Examination Methods for Public Places. The results were evaluated according to Architectural Technical Code for Hospital Clean Operating Department (GB50333-2002). Results The concentration of airborne particles and bacteria in the investigated clean operating rooms were eligible with a qualified rate of 100%. A correlation was seen between the airborne particles and bacteria, the correlation coefficients were 0.306 for the particle of 0.5 ?m and 0.074 for the particle of 5.0 ?m. The qualified rate of other items such as the static pressure difference, illuminance, relative humidity, temperature, noise, wind velocity and air exchange rate were respectively 100%, 94.4%, 88.9%, 83.3%, 83.3%, 83.3%, 33.3% and 38.5%. Conclusion The qualified rate of the main clean indexes of the clean operating rooms in hospitals in Guangzhou city is comparatively high, but some of the other indexes related to the air quality should be paid more attention in usual application and maintenance.

OBJECTIVE:To analyze the renal lesions induced by oral preparations of traditional Chinese medicines so as to provide theoretic basis for clinical rational drug use.METHODS:The CNKI full-text database between January 1991 and December 2008 were retrieved for clinical reports of renal lesions induced by oral preparations of traditional Chinese medicines.And the pertinent literature was sorted,analyzed and compared.RESULTS:176 reports(totaled 619 cases)were collected.Repeated long-term medication and overdosing etc were the major factors accountable for the renal lesion.CONCLUSION:Importance should be attached to the nephrotoxicity of oral preparations of traditional Chinese medicines,and which should be used rationally in the clinic and periodic examination of patients' renal function should be performed in taking oral preparations of traditional Chinese medicines.
