Vertigo is a kind of patients' subjective feelings. The severity of vertigo is closely related to many factors. But we are short of a well accepted quantitative evaluation method capable of accurately and comprehensively evaluating vertigo in clinics. Reducing the onset of vertigo, enhancing the re- covery of equilibrium function, and improving the quality of life of vertigo patients should be taken as the focus of evaluating therapeutic effects. As for establishing a Chinese medical effectiveness evaluation system for vertigo, we believe we should distinguish different "diseases". We could roughly identify it as systemic vertigo and non-systemic vertigo. For systemic vertigo, the efficacy of vertigo could be comprehensively evaluated by UCLA vertigo questionnaire or dizziness handicap inventory combined with equilibrium function testing indices. But for non-systemic vertigo, the efficacy of vertigo could be comprehensively evaluated by taking UCLA vertigo questionnaire or dizziness handicap inventory as main efficacy indices. Secondly, we should analyze different reasons for vertigo, choose symptoms and signs in line with vertigo features as well as with Chinese medical theories, and formulate corresponding syndrome effectiveness standards according to different diseases. We should not simply take syndrome diagnosis standards as efficacy evaluation standards.

Objective To observe the tissular pathological and ultrastructural changes of gastric mucosa with experimental atrophic gastritis caused by salt-water in rats and to explore the relationship between atrophic gastritis and high-salt diet.Methods The atrophic gastritis rat model was made by salt-water perfusion(0.15g/ml,2.5ml/d).The tissue of sinus ventriculi was detected with histopathologic examination and the ultrastructure of gastric mucosa was observed by scanning electron microscope.Results Under light microscope,the gastric gland was shrunk obviously in high-salt water perfusion group after high-salt water was given for 24 weeks.The muscle in muscular layer was hyperplasia and cramped into the lamina propria.The glandular epithelium in the upper 1/3～2/3 edge of the gland was atrophic.The gastric micro-depression became broaden and the width of cervical part of gastric pit became narrow.Under the scanning electromicroscope,the gastric mucosa was comparted into many gastric areas in the control group.Round or elliptic epithelium cells lined on the wall of gastric pits were in the same size and had short and spare microvillus.The epithelium was lined regularly and covered by laminar mucus.In salt-water perfusion group after the salt-water was given for 24 weeks,the surface of the gastric mucosa became thin and flat,and the glandular cells became rough.The mucosa between lumens of gland was broadened and the limited exfoliation of mucosa also could be seen.When the salt-water was given for 32 weeks,the gastric epithelial cells were shrunk,and the diameter of lumen of gland was broadened.There was breakage in the cell surface.Erosions with various size and shape and fibrous exudation could be seen.Conclusion Salt-water perfusion may cause the damage of the epithelia of gastric mucosa in experimental rats and long-term high-salt stimulation can induce the injury and atrophy of gastric mucosa.

Objective To assess the value of CT in diagnosis and clinical treatment of the traumatic rupture of spleen.Methods There were 35 cases with traumatic repture of spleen,32 cases were comfirmed by operation.Plain CT scans in all cases and contrast-enhanced scans in 4 cases were performed.Results 19 cases were subcapsular hematoma,8 cases were spleen hematoma,6 cases were rended in one place of spleen,2 cases were rended in many places of spleen.Conclusion The difinite diagnosis and classification of traumatic rupture of spleen can be made by CT.The rupture of the organs around the spleen also can be found by CT,that can provide reliable evidence for clinical treatment.

Objective To investigate the incidence and possible reasons of patients with rheumatoid arthritis (RA) who stopped taking slow-acting antirheumatic drugs (SAADs).Methods Two hundreds and twenty-four in-or out-patients with RA were prospectively followed up for 4-year,and their demographic and clinical information and reasons of SAADs cessation were recorded.The difference between patients who stuck to SAADs and those who stopped SAADs and the factors that resulting the cessation were analyzed.Results ① Fourty-eight percent of 224 patients with RA ceased taking SAADs during 4-year period.② The main reasons of ceasing SAADs,provided by patients themselves,were side effects of SAADs,ineffectiveness,lack of knowledge about drugs,short of SAADs,concurrent diseases,and intention to pregnancy.③ There was significant difference in low income,poor educational status,number of tender joints,and rheumatoid factor level between the patients who stuck to SAADs and those who did not.Conclusion The high incidence of SAADs cessation in RA patients should rise concern.Both medical and patient factors contribute to the cessation.

Objective To investigate the changes of blood pressure in rats with experimental brain infarction caused by use of mild hypothermia. Methods One hundred and twenty Sprague Dawley rats were used and divided randomly and equally into a control group and an experiment group. In all of the rats, the middle cerebral artery occlusion (MCAO) was made to cause the experimental brain infarction, and reperfused 2 hours later. Three hours after MCAO, the rats in the experiment group were placed in the 4℃ with the rectal temperature controlled at 34? 1.0℃ , while those in the control group in the room temperature. The heart rate, breath, blood pressure, oxygen saturation and rectal temperature were monitored. The rats were sacrificed 24 hours after MCAO and the infarction volume were observed. Results After MCAO, the blood pressure was significantly increased as compared with that prior to MCAO ( P 0.05) . Hypothermia significantly reduced the blood pressure after being used for more than 3 hours ( P

Objective Based on dual channel melting curve analysis-based assay,we developed a method to rapidly detect the drug-resistant mutations in Mycobacterium tuberculosis through real-time PCR.Methods According to the common first-line drug-resistant mutations of Mycobacterium tuberculosis,we designed six dual-labeled fluorescence probes to rapidly detect the drug-resistant mutations through realtime PCR melting curve after amplifications of drug-resistant related gene region of DNA.The targets include rpoB 81 bp core region,katG315,inhA promoter,ahpC promoter and embB306.To validate the sensitivity and specificity of our method,we performed real-time PCR assays to detect drug-resistant mutations in 76 clinical MDR-TB samples,which were collected by Shanghai CDC in 2008.Results In the validation,this method successfully detected drug-resistant mutations in all 76 clinical MDR-TB samples.The △Tm of mutations were from 1.8 to 14.4 ℃.Comparing with the sequencing data,all mutations covered by the six probes were detected with 100％ sensitivity and 100％ specificity (rpoB,80/80; inhA,7/7 ; katG315,59/ 59;ahpC,8/8;embB306,27/27).This method can successfully detect drug-resistant mutations from 100 copies/μl DNA samples.Conclusions A widely applicable real-time PCR assay to detect first line drug-resistant mutations of Mycobacterium tuberculosis has benn developed.This method has proven to have the advantages of high sensitivity,specificity and low risk of contamination.It can be used in rapid diagnosis of clinical drug-resistant tuberculosis and the evaluation of laboratory drug sensitivity test.

AIM To study whether nitric oxide preconditioning induce early protection of neonatal rat cardiomyocytes. METHODS Cultured neonatal rat cardiomyocytes were divided into 6 groups. ①Normal group;②NO group: SNAP(500 ?mol?L -1 ) was added to cell medium 1 h before lethal hypoxia/reoxygenation (HR) injury (6 h hypoxia and 3 h reoxygenation); ③HP group: Cells were cultured for 60min hypoxia followed by 30 min reoxygenation to form hypoxia preconditioning before lethal HR injury;④ L NAME+HP group: Nitric oxide synthase antagonist L NAME was added during HP stage;⑤ L Arg group: L arginine was added to cell medium 1h before lethal HR injury;⑥ L NAME+ L Arg group: Both L NAME and L Arg were added to cell medium 1 h before lethal HR injury;⑦H/R group: Cells underwent lethal HR injury without any treatment. Cardiomyocytes injury was detected by lactate dehydrogenase(LDH) activity and cell viability. RESULTS Nitric oxide preconditioning can protect cardiomyocytes by reducing LDH activity and improving cell viability ( P
