Objective To understand the attitude of health workers towards people living with HIV and AIDS(PLWHA) and AIDS knowledge and desire for related training among them in selected hospitals in Beijing.Method Convenience sampling was used to select health workers from 32 hospitals of different levels in 4 districts within Beijing.Anonymous self-administrated questionnaires were used to collect the information regarding AIDS knowledge and desire for relevant training.Results A total of 1 292 health workers completed the questionnaire.They demonstrated a moderate level of general AIDS knowledge,but a low level of knowledge related to AIDS diagnosis and therapy.Of them 39.7% had received specialized AIDS training and 96% had strongly desire for such specialized training.Most health workers sympathized with PLWHA and understood their situation,while some of them were afraid of PLWHA and wanted to have minimal contact with PLWHA.91.3% of the health workers expressed that PLWHA should have the same rights to medical services.At the same time,49.2% of the health workers stated that they would not like to work in hospitals or departments which accepted PLWHA.80% of the health workers expressed concern over acquiring HIV infection in the workplace.52.7% of them thought that they had a risk of becoming infected in the workplace.Conclusion The level of AIDS knowledge among health workers in Beijing needs to be improved.Specialized training to enhance and develop health workers knowledge of prevention,diagnosis and treatment of AIDS is required.Most of the health workers do not discriminate against PLWHA,but they express concern over infection in the workplace.

Objective To develop the Chinese version of the 35-item Medical Outcomes Study HIV Health Survey (MOS-HIV) and to assess the reliability and validity of MOS-HIV among HIV-infected individuals.Methods Between April and July of 2007,a croas-sectional survey of 758 HIV-infected individuals was conducted.Responses to the MOS- HIV were analyzed for its reliability and validity.Results Pearson's correlation coefficients of items for test-retest relia- bility ranged from 0.46-0.92,all internal consistency reliability coefficients exceeded 0.69,and all items were more strongly correlated with hypothesized scale than any other scale.Eight scales of MOS-HIV were significantly associated with CD_4 cell counts.Conclusions The Chinese version of MOS-HIV offers good reliability and validity and can be used as a tool to assess the quality of life of HIV infected individuals in China,thus providing evidence for further studying AIDS related quality of life in this country.

Objective To analyze the clinical features of pandrug-resistant Acinetobacter baumannii (PDR-Ab) in a hospital and compare the efficacy of different antibiotic treatments on patients with pneumonia caused by PDR-Ab.Methods Data were ret- rospectively collected from all isolated PDR-Ab strains in our hospital from February 2004 to March 2005.The clinical features and outcomes were reviewed.Results A total of 77 strains of PDR-Ab were collected, 45 of which were pathogens causing clini- cal infections (35 strains from lower respiratory tract, 6 from bloodstream, 3 from drainage fluid, and 1 from wounds).Lower respiratory tract was the most common source of PDR-Ab.More than 90% of the isolated PDR-Ab strains produced OXA-23 type?-lactamase.Cefoperazone-sulbactam plus minocyeline showed good efficacy for patients with PDR-Ab pneumonia.The total clinical cure rate was 68.4%.Bacterial eradication rate was 42.1%.The factors influencing bacterial clearance were pro- longed mechanical ventilation prior to positive culture (17.5 d vs 5.5 d).mixed infection (100% vs 12.5%) and lower GCS score (9.1?0.7 vs 13.2?2.1).Concomitant septic shock (OR=13.8) and APACHEⅡscore (OR=2.1) were independent factors of clinical outcome.Conclusions Nosocomial infections caused by PDR-Ab are not untreatable.Our analysis suggests that cefoperazone-sulbactam plus minocycline may be an effective treatment for lower respiratory tract infections caused by PDR-Ab in our hospital.

Objective To study the association between clinical symptoms,psychosomatic factors and autonomic nervous function in patients with gastroesophageal reflux disease (GERD).Methods Thirty-four patients with GERD diagnosed by reflux disease questionnaire (RDQ) and endoscopy and 15 healthy control subjects were enrolled in this study.All the subjects were divided into two groups,one with normal scores of Zung's self-rating anxiety scale (SAS) and Zung's depression scale (SDS) as GERD (-) and the other with abnormal scores of SAS and SDS as GERD (+).Reflux symptom score was recorded for both groups at the same time.Autonomic nervous function was assessed by their heart rate variability (HRV) on dynamic electrocardiogram (DCG).The time domain parameters analyzed included standard deviation (SD) of average R-R interval during 24 hours (SDNN),SD of average 5-minute sinus heart rate (SDANN),mean square root of the difference of adjoining two R-R interval (rMSSD),and proportion of the heart beats with difference of R-R interval more than 50 ms from the total heart beats (PNN 50),and the frequency domain parameters analyzed included low-frequency (LF),high-frequency (HF) and ratio of LF to HF.Results Average scores of SAS and SDS were significantly higher in patients with GERD than those in healthy controls (48?9 vs 38?6 and 48?11 vs 41?6,respectively,P

Objective To investigate the clinical manifestions, pathological features and diagnosing methods of Lafora disease. Methods The chnical and pathological features of 5 patients with Lafora disease who were diagnosed by axillary biopsies were systemically studied. The specimen were stained by HE, PAS and AB-PAS methods. Results Four of 5 cases had an onset during adolescence and 1 during adulthood. All cases presented with progressive generalized tonic-clonic seizure, myoclonus and dementia. Emotional disturbance, dysarthria and ataxia appeared in the early course of the disease. Lafora bodys were identified in myoepithelial cells and duct cells of both eccrine sweat glands and apecrine sweat glands in the biopsies of axillary skin. Conclusions Lafora disease could be confirmed by round and oval periodic acid-Schiff- positive inclusions in skin biopsy specimen combined with the proper clinical settings. Both axillary and other skins can be chosen as the sites of biopsy.

OBJECTIVETo review the mechanisms of epithelial to mesenchymal transition (EMT) and its role in the progression of tubulointerstitial fibrosis.

DATA SOURCESThe data used in this review were obtained mainly from the studies of EMT reported from 2000-2006.

STUDY SELECTIONRelevant articles on studies of EMT in tubulointerstitial fibrosis were selected. Data were mainly extracted from the 45 articles listed in the reference section of this review.

RESULTSThe process of EMT has gained wide recognition as candidate mechanism in progression of chronic fibrotic disorders. New markers were identified and facilitate the observation of EMT. EMT is regulated by many factors through activation of kinase-dependent signaling cascades. Recent findings suggest that EMT is a reversible process, which can be controlled by factors for their epithelial inducing activities.

CONCLUSIONRemarkable progresses of EMT research have been made recently. Preventing or reversing EMT is a promising strategy against renal fibrosis.

OBJECTIVEIn this study, five heavy metals contamination of soil and different parts of Panax notoginseng in the plantation area was investigated. Analysis of heavy metals correlation between the planting soil and P. notoginseng; and the absorption and accumulation characteristics and translocation of soil heavy metals by P. notoginseng plants was revealed.

METHODThrough field investigation and laboratory analytical methods, analysis of China's 30 different soil P. notoginseng origin and content of heavy metals in five different parts of the P. notoginseng plant content of heavy metals.

RESULTThe results revealed that the soil heavy metals should not be neglected in the plantation area Referring to the national soil quality standards (GB15608-1995), the excessive degree of soil heavy metals pollution showed Hg > As > Cd > Cr in the plantation area, and Pb content of soil was in the scope of the standard. Refer to 'Green Industry Standards for Import and Export of Medical Plants and Preparations', the excessive degree of heavy metals content of P. notoginseng plants showed As > Pb > Cr > Cd, and Hg content of plants was in the scope of the standard. Concentrations of five heavy metals of underground parts of P. notoginseng plants are higher than aboveground, and heavy metals elements are more concentrated in the root, followed by the rhizome of P. notoginseng plants. Heavy metal accumulation characteristics of the different parts of the P. notoginseng of the overall performance is the root > the rhizome > the root tuber > leaves > stems. From the point of view BCF value analysis of various parts of the P. notoginseng plants to absorb heavy metals in soil, BCF values of all samples were less than 1, description P. notoginseng not belong Hyperaccumulator. From the view of transportation and related analysis of the soil-P. notoginseng systems, the rhizome of P. notoginseng and the content of As and Cr in soil was significantly correlated, the root of P. notoginseng and the content of Cd in soil was significantly correlated, and no significant correlation between the other indicators. Through the analysis of transportation transfer coefficient showed: Pb, As and Cr are not easy to transport aboveground part from the underground, but Cd and Hg are relatively easy to transport stems from rhizome, the migration of five heavy metals in the aerial part is relatively strong, and heavy metal of stems is easily transported to the leaves.

CONCLUSIONP. notoginseng does not belong to the enrichment of heavy metals in crops, especially for Hg in soil with strong patience. In survey area, the content of heavy metals of P. notoginseng's planting soil is relatively high, and the heavy metals As, Pb, Cr, Cd of P. notoginseng also exist heavy metals exceeded problems. Due to the presence of heavy metals in crops internal absorption and translocation of special laws, accumulation of heavy metals varied significantly in different parts of P. notoginseng. The overall, the performance for the heavy metal content of the underground parts is more than aboveground, it explain heavy metals of P. notoginseng plants is still the main source of the soiL Therefore, the key to control of planting area soil environmental quality and reduce exogenous harmful substances secondary pollution of soil in the cultivation process are to study and solve the heavy metals pollution problem of P. notoginseng.
