Objective To review 2006-2007 AIDS response in China by applying the indicators of "Monitoring & Evaluation Plan of AIDS Response". Method Data from the national AIDS routine reporting system and special survey in line with the definitions of the indicators and standardized methods were summarized,classified and analyzed; mid-term targets or indicator value of 2005 were employed as comparison. Results The 2007 result of the national HIV sentinel surveillance showed that the HIV prevalence among female sex workers,injecting drug users,men who have sex with men and pregnant women was 0.0%,1.9%,3.1% and 0.0% respectively;the data from the national HIV comprehensive response information system showed that by the end of 2007,72.8% of the adults and children with advanced HIV infection had received antiretroviral therapy (ART) ,and 83.6% of the ART receivers survived after 12 month treatment. Conclusion Indicators of the "Monitoring & Evaluation Plan" are able to reflect the outcomes and achievements of 2006-2007 HIV/AIDS response in China,which has made good progress and has fulfilled the mid-term targets as defined by the Plan.

Objective To examine the distribution of Malassezia species in follicular contents and perifollicular superficial skin in patients with Malassezia folliculitis and search for its causative agent. Methods A total of 120 patients with Malassezia folliculitis were investigated. Follicular lesions at three different anatomic sites were selected in each patient. Perifolliclar superficial skin specimens were taken by sterile adhesive tape, and the follicular contents of the same follicle were taken by sterile haemostatic forceps. The above specimens were cultured respectively on media containing rapeseed oil. The isolated colonies were identified by their physiological and morphological characteristics. Results Out of 319 isolates obtained from the perifollicular superficial skin, 247 isolates (77.43%) were identified as M. sympodialis, 40 isolates (12.54%) as M. furfur, 27 isolates(8.46%) as M. globosa and 5 isolates(1.57%) as M. obtusa. Out of 314 isolates obtained from follicular contents, 252 isdates(80.25%) were identified as M. globosa, 57 isolates(18.15%) as M. sympodialis, 4 isolates(1.27%) as M. furfur, and 1 isolate(0.32%) as M. obtusa. There was statistical difference in species distribution between the follicular contents and the perifolliclar superficial skin (P

Objective To discuss clinical value of 64-slice spiral CT scanning in fast evaluation of severe multiple trauma.Methods A retrospective study was carried out on data of 72 multiple trauma patients diagnosed with systemic 64-slice spiral CT scanning in our hospital from January 2006 to June 2008.Of all,28 patients with traffic injuries,24 with falling injuries,10 with blunt injuries,6 with stab injuries and 4 with explosive injuries.Results There were 72 multiple trauma patients with mean scanning time of 10.2 seconds.The CT scanning showed both craniocerebral and thoracic injuries in 30 patients,brain injuries in 16,thoracoabdominal injuries plus pelvic injuries in 10,extremity and brain injuries in 14 and systemic soft tissue injuries in 2.Isotropic characteristics and postprocessing function of 64-slice spiral CT scanning could accurately diagnose and evaluate injury severity of multiple trauma.Conclusions 64-slice spiral CT scanning is a fast and effective method for fast evaluating injury severity of multiple trauma,for it can not only shorten checking time,reduce movements of the patients and relieve the pain of the patients,but also can avoid defects induced by respiratory movement and provide fairly integrated imaging materials by its isotropic characteristics and pestprecessing function.

Objective To observe the therapeutic effect of rhubarb combined with Probiotics for treatment of patients with severe acute pancreatitis (SAP) accompanied by acute lung injury (ALI). Methods A prospective randomized controlled trial was conducted. Sixty patients with SAP and ALI were randomly divided into a rhubarb group and a combination of rhubarb and Probiotics group (combined group), 30 cases in each group. Both groups were treated with conventional therapy. On that therapeutic base, the patients in rhubarb group were treated with rhubarb 3 g·kg-1·d-1 (Raw rhubarb in boiling water 200 mL was cooked for 30 minutes, then the decoction was divided into two parts to be infused through nasal jejunal tube, retaining for 1 hour);while in the combined group, beside the above rhubarb therapy, the patients were additionally given Probiotics [Clostridium butyric acid:Chang Lekang capsule, once 1 grain (0.42 g), twice a day] through nasal jejunal tube. The therapeutic course was 14 days in the two groups. The plasma endotoxin levels, oxygenation index, and acute physiology and chronic health evaluationⅡ(APACHEⅡ) score were observed before and after treatment for 7 days and 14 days, respectively. After treatment for 30 days, the time of intestine functional recovery and mechanical ventilation, number of damaged organs, number of infectious sites, number of pancreatic pseudocysts, length of intensive care unit (ICU) stay and 30-day fatality rate were observed in the two groups. Results With the prolongation of treatment, the plasma level of endotoxin and APACHEⅡscore in the two groups were gradually reduced, and the oxygenation index was gradually increased after treatment for 7 days and 14 days in the two groups compared with those before treatment, and there were statistically significant differences in above indexes on the 14th day after treatment between combined group and rhubarb group [endotoxin (μg/L): 19.16±1.90 vs. 21.20±1.05, oxygenation index (mmHg, 1 mmHg = 0.133 kPa): 369.50±5.45 vs. 341.50±7.36, APACHE Ⅱscore:11.84±0.60 vs. 13.00±0.86, P<0.05 or P<0.01]. The length of intestine functional recovery in the combined group was longer than that in the rhubarb group (days: 5.63±1.75 vs. 5.02±1.54), the number of damaged organs (2.08±0.74 vs. 2.70±1.11), the number of infectious sites (1.93±0.64 vs. 2.23±0.83), the number of pancreatic pseudocysts (1.22±0.34 vs. 1.63±0.11) and the mortality rate [10.0%(3/30) vs. 13.3%(4/30)] in the combined group were lower than those of the rhubarb group, but there were no statistically significant differences between two groups (all P > 0.05). The times of mechanical ventilation (days: 13.40±1.76 vs. 15.60±1.28) and the length of ICU stay (days:16.13±1.25 vs. 17.63±1.30) were significantly shorter in combined group than those in rhubarb group (both P<0.05). Conclusion Rhubarb combined with Probiotics for treatment of patients with SAP and ALI can promote their recovery of lung function and shorten their length of ICU stay.

Objective To investigate the distribution of Malassezia species in lesional and non-lesion-al sites of patients with pityriasis versicolor(PV),species-variation in different anatomic sites and in lesions with different pigmentation,and the relationship between various Malassezia species and severity and age of PV patients.Methods A total of629skin specimens taken by sterile adhesive tape from the lesions and non-lesional skin were inoculated on media containing rapeseed oil in113patients with PV.Isolated colonies were identified to species based on physiological and morphological characteristics.Results The isolation rates of Malassezia spp.were not significantly different from both lesions and corresponding non-lesional skin.Among non-lesional sites,the isolation rate was significantly higher in forehead and trunk than that in upper and lower extremities.Five species were identified out of565strains obtained from the patients,including M.sympodialis(44.78%),M.furfur(32.94%),M.globosa(11.68%),M.obtusa(5.84%)and M.restricta(4.76%).Two dif-ferent species were isolated simultaneously from27sites.There was no obvious difference in species distribu-tion patterns between lesions and non-lesional sites.M.restricta was isolated from forehead exclusively.Species-variation was closely linked to lesions with different pigmentation and the age of patients,not to the severity of disease.Conclusion There is neither statistical difference of Malassezia isolation rate and species distribution between lesions and non-lesional skin,nor correlation between disease severity and species-varia-tion.The anatomic sites,the diversity of pigmentation pattern and the age of patients seem to be associated with different Malassezia species.

Objectives To compare the difference between multipoint inoculation and routine method for isolation of pathogenic fungi from nail samples of onychomycosis,and to analyze the epidemiology of pathogenic fungi in those patients.Methods The nail clipping samples from each patient were inoculated onto the plates with Sabouraud's agar,Sabouraud's agar without cycloheximide and medium containing rapeseed oil,respectively,by an approach of at least seven inoculating points in each plate (multipoint inoculation),and onto medium slope in tubes with the same media as above mentioned (routine method).In the multipoint inoculation method,plates with more than 3 colonies were taken for further identification of pathogenic fungi based on morphological and biochemical properties.Results Based on the data from 150 samples of onychomycosis,significant differences were found between multipoint inoculation method and routine method (P

ObjectiveTo assess the characteristics of left ventrlcular ( LV) systolic syncnrony before and 6 days after percutaneous transluminal septal myocardial ablation(PTSMA)in patients with hypertrophic obstructive cardiomyopathy (HOCM) using two dimensional speckle tracking imaging(2DSTI),and to investigate correlation between the LV systolic synchrony and LV outflow-trace gradient (LVOTG).MethodsLVOTG were measured before and 6 days after PTSMA in 21 patients with HOCM.The two dimensional loop-cinec were obtained in three levels of the short axis views of LV (mitral valve,papillary muscle and cardiac apex).The time from the onset of QRS complexes to systolic peak strain from the radial vectors (TRs) was recorded using 2D-STI.The standard deviation of the TRS of 18 segments (TRsSD) were calculated as indicator of LV systolic synchrony.Results Six days after PTSMA,LVOTG decreased significantly from (84.3 ± 19.1)mm Hg to (40.6 ± 8.3)mm Hg( P ＜0.01).TRS of the base and middle segments of anteroseptal were prolonged dramatically( P ＜0.05) 6 days after PTSMA compared with that before.There were no significantly differences in TRs-SD of LV between before and 6 days after PTSMA ( t =1.03,P ＞ 0.05).Decreased LVOTG correlated moderately to prolonged TRS of the base segments of anteroseptal ( r =0.657,P ＜0.05).Conclusions2D-STI can detect exactly the characteristics of LV systolic synchrony before and 6 days after PTSMA in patients with HOCM.
