Objective To investigate the prevalence,radiological features and the association between HRCT changes and different diseases or clinical features in interstitial lung disease(ILD)caused by diffuse connective tissue diseases(CTD).Methods Retrospective analysis was performed based on the medical records of 412 in-patients with the diagnosis of diffuse connective tissue diseases from June 2003 to June 2005 in our hospital.268 cases were SLE,83 cases were SS,40 cases were DM/PM,21 cases were SSe.All patients had chest X-ray and the suspected cases had HRCT exam.The distribution of ILD among different diffuse CTD.the appearance between X-ray and HRCT appearances were compared.The correlation among HRCT appearance,different diseases and clinical features was studied.Results①In the 412 cases of CTD,ILD de- tected by HRCT was 9.7%(40 case in total),3,9% by X-ray.Among the 40 cases,DM/PM had the highest rate of ILD(25%),23.8% in SS,9.6% in SS and 6.3% in SLE.②The consensus rate between HRCT and X-ray was 40%.The rate of mis-diagnosis of ILD was 60% by X-ray.③The changes of interstitial involvement de- tected by HRCT were:ground glass change(41.0%),consolidation(32.8%),reticular change(16.4%)and hon- eycomb change(9.8%).The concomitant presence of two of the above changes were very common.④More level respiratory symptoms such as cough,panting,chest distress and chest pain and high level of complement were observed in patients with ground glass and consolidation changes,while high CRP level was seen in patients with consolidation and honeycomb changes(P

OBJECTIVESearching and identifying SNP in Panax species and using multiplex allele-specific PCR (MAS-PCR) to authenticate P. ginseng and P. quenquefolium.

METHODBased on genbank database of Panax species, using DNAMAN to align the sequences, identify SNP of P. ginseng and P. quenquefolium. Design allele-specific primers for P. ginseng and P. quenquefolium, optimize the PCR reaction system including the usage amount of Taq, dNTP, primer, etc. Optimized system was performed with the total DNA of 20 different sources of P. ginseng and P. quenquefolium.

RESULTWhen the annealing temperature was 66 'C, the template DNA of P. ginseng could be amplified 249 bp band whereas P. quenquefolium amplified 1 049 bp band.

CONCLUSIONThe MAS-PCR have the advantages of highly specific, good reproducibility and could be identify P. ginseng and P. quenquefolium in the same PCR tube. It was a potential method to use in the molecular identification of other meteria medica.

OBJECTIVETo observe the clinical effects of Qiyao Xiaoke Capsule (QXC) on patients with type 2 pre-diabetes.

METHODSTotally 116 pre-diabetes patients were randomly assigned to the Chinese medicine group (CM, 76 cases) and the blank control group (BC, 40 cases) in the ratio of 2: 1. All patients received proper diet control, health education, and exercises, and so on. Besides, patients in the CM group took QXC (0.4 g/pill), 6 pills each time, three times a day. But patients in the BC group were intervened by life style alone. The fasting blood glucose (FBG), postprandial blood glucose (PBG), insulin (FINS, 2h INS), glycosylated hemoglobin (HbAlc), blood lipids (TG, TC, HDL-C, and LDL-C), and efficacy of CM symptoms were observed in the two groups before and after intervention. The sequelae were observed at the end of the treatment and at follow-ups.

RESULTSAfter treatment FBG, PBG, and HbA1c decreased in all patients of the two groups (P<0.05, P<0.01), with 2 h PBG decreased more significantly. But there was no statistical difference between the two groups (P>0.05). The two methods could improve the secretion of FINS. Especially 2 h INS decreased more significantly in the CM group, showing statistical difference when compared with the BC group (P<0.05). The two methods could improve the metabolism of blood lipids. CM could significantly lower TG and elevate HDL-C, showing statistical difference when compared with before treatment (P<0.05). After treatment the CM symptoms were obviously improved, showing statistical difference when compared with the BC group (P<0.05). The normalization rate was better in the CM group than in the BC group at the end of the treatment and at follow-ups (P<0.05).

CONCLUSIONSQXC combined life style intervention could improve fasting and postprandial insulin secretion of type 2 pre-diabetes patients, regulate glycolipid metabolism, correct the insulin resistance state, and improve the symptoms of qi-yin insufficiency. It could postpone or hinder the occurrence and development of type 2 diabetes. It was more effective and durable than changing the life style alone.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

Objective To identify the gene mutation of G protein?-subunit (Gsct) in multiple affected tissues of a patient with McCune-Albright syndrome.Methods The peripheral blood,bone tissue,lesion skin and pleura samples of the patient were collected.Genomic DNA was isolated from these samples,and PCR and direct sequencing were performed.Results The peripheral blood and bone tissue of the patient showed a mutation R201C in Gs?gene.No mutation was detected in the skin and pleura samples of the patient.Conclusion The gene diagnosis confirms that the patient has a classical R201C mutation in Gs?gene and multiple tissues are affected.The mutation occurs early in embryogenesis and clinical features can be polymorphic.

0.05).Overall prevalence of UI was 15.93% in the students,20.45% in those of junior high school,10.44% in senior high school and 16.72% in university(P0.05),accounting for 63.90%,10.47% and 25.63% of the total students with UI.Conclusions Great importance should be attached to the higher prevalence of LUTS in young and adolescent females by gynecologists and urologists.More attention should also be paid to health education on LUTS and medical care for those with LUTS to alleviate and delay occurrence of UI symptoms.

Background Stromal cell-derived factor-1_?(SDF-1_?)has been demonstrated to be essential for stern cell mobilization/homing.Recent evidence indicates that SDF-1_? has been expressed in injured carotid arter- ies.Besides,high SDF-1_? plasma levels are clinically associated with stable coronary artery disease.Objective To investigate whether SDF 1 involves in mobilization of endothelial progenitor cells(EPC)and reendothelialization after vascular injury.Methods SDF-1_? was detected by RT-PCR and Western blot in carotid arteries of mice at different time points after wire-induced injury.SDF-1_? determination in peripheral blood samples and BM was per- formed by SDF-1_? enzyme-linked immunosorbent assay(ELISA)kit.EPC in peripheral blood collected at different time points after vascular injury were quantified by flow cytornetry.In subgroup,blocking SDF-1 rnonoclonal anti- body was injected,peripheral blood EPC were quantified after vascular injury and reendothelialization of injured ar- teries was determined 14 days later.Results Expression of SDF-1_? was evident at day 1,and peaked at day 3 after arterial injury.A rise in plasmatic concentration of SDF-1_? and a significant reduction of SDF-1_? in bone marrow concentration was noticed at all time points following injury.The amount of circulating EPC was increased shortly after induction of vascular injury and persisted up to 7 days(P
