Objective To evaluate the influences of high hydrostatic pressure (HHP) on the virulence and antigenicity of Coxsackie virus B3 (CB3 V) , to explore a new physiological method to develop an active vaccine against Coxsackie virus. Methods The phagocytosis of the macrophages in mice to the CB3 V and the TCID50 of the CB3V before and after treated by HHP were examined. Results TCID50 increased from 10-5 to 10-4 when treated by 680 MPa; viruses were inactivated at 700 MPa. Viruses were also inactivated by the pressure less than 700 MPa, but needed prolonged time. The phagocytic function, antibody and T lymphocyte transformation rate in experimental mice (heated, attenuated, and inactive viruses) exhibited a significant difference compared with control mice (P

OBJECTIVE To establish secretory otitis media(SOM) model induced by endotoxin and evaluate its reliability. METHODS Healthy 50 Sprague-Dawley rats of either sex( 250-300g)were randomly divided into experimental group(ET group) and control group(NS group),with 30 and 20 rats respectively. 35ul volume of 1mg/ml endotoxin from Pseudomonas aeruginosa and same amount of saline(NS) were transbullaly injected into the right tympanic bullas of the two groups. Six rats of ET group and four rats of NS group were killed postoperative on 6h,1d,3d,7d,14d respectively. The temporal bones were harvested for histological study. The left tympanic bullas served as control. Another four rats(each group 2 rats) were used for SEM study with the same method. One rat was killed and harvested for SEM observation of mucocilliary transporting system on the tympanic ostium of Eustachian tube. RESULTS ①LM(light microscope):The epithelial layer and subepithelial space(SES) were thicked mildly in ET group at 6 hours,and more heavily at 1 day with inflammatory cells infiltration (mostly polymorphonuclear leukocytes,PMNs). At 3 days,the same changes were observed most severely. By 14 days,the mucosal lining returned to normal. No obvious changes were observed in the NS group. ②SEM(scan electrical microscope):In ET group,the impairment of mucociliary transport system such as lodging,shedding of cilias were observed at 3 days and returned to normal at 14 days. No abnormal changes were observed in NS group. CONCLUSION Endotoxin can induce SOM with inflammatory changes peak at day 3 and return to normal by day 14.

AIM To investigate the effects of piroxicam on transplanted Sarcoma S180 and the expression of COX 2,VEGF,FGF 2 and microvessel density (MVD) in tumor tissue METHODS Kunming mice were randomizedly divided into control group, FT207 positive group and 5, 2 5, 1 mg?kg -1 piroxicam groups One day after inoculation of 0 2 ml S180 cell suspension, FT207 and piroxicam were given by gastric intubation for 9 days The inhibitory rate on S180 was calculated routinely The expression of COX 2,VEGF,FGF 2 and MVD was detected by immunohistochemistry RESULTS The growth of S180 was significantly inhibited by piroxicam at the doses of 5, 2 5, 1 mg?kg -1 with the inhibitory rate of 31 4%,40 7% and 34 9% respectively The expression of COX 2 in the tumor tissue was also inhibited by piroxicam. Accordingly the expression of VEGF,FGF 2 and MVD was markedly inhibited in dose dependent manner by piroxicam CONCLUSIONS The results suggest that piroxicam has inhibitory effects on S180,and it also decreases the expression of COX 2 in tumor tissue. There is a relation ship between the expression of COX 2 and angiogenesis related factor Antiangiogenesis may be another mechanism for piroxicam to exert its chemopreventive and treatment effects.

Objective To observe the effects of intensive lower extremity motor control training on the motor function of lower extremity, balance and walking capability of stroke patients. Methods 40 stroke patients were randomized into the intervention group (n=20) and control group (n=20). Both groups received the routine rehabilitation, while the intervention group accepted the lower extremity motor control training in addition for 6 weeks. Before and after 6 weeks of treatments, they were assessed with Fugl-Meyer Assessment of lower extremity (FMA-L), Berg Balance Scale (BBS), Holden Functional Ambulation Category (FAC); their gaits were analysesd with footprint. Results Both groups improved significantly in scores of FMA-L, BBS, FAC and average step length, stride width, walking velocity (P<0.01) after treatment, and improved more in the intervention group than in the control group (P<0.05). Conclusion Intensive motor control training of lower extremity may promote the recovery of motor function of lower extremities, balance and walking ability of stroke patients.

Objective To explore the efficacy of process management on bladder function among traumatic brain injury (TBI) patients admitted to intensive rehabilitation and care unit (IRCU). Methods 33 cases were collected to control group who were cared with routing nursing during February, 2011 to December, 2012. Other 39 cases were recruited to trial group cared with process management of bladder function during January, 2013 to December, 2014. Process management of bladder function contained the establishment of process manage-ment guide, evaluation of removing catheter, nursing of bladder based on residue of urine volume and keeping a diary of urination, etc. Re-sults There were more cases with residue of urine volume less than 100 ml and less with catheter associated urinary tract infection in the tri-al group than in the control group (P<0.05). Conclusion Process management of bladder function can improve the recovery of bladder func-tion of TBI patients, shorten rehabilitation time and decrease the risk of catheter associated urinary tract infection.

Objective To analyze the epidemiological characteristics of the imported malaria cases in 20 counties at the bor?der region of Yunnan Province from 2012 to 2014,so as to provide the evidence?based proof for adjusting the strategies in the elimination stage. Methods The malaria epidemic data of the 20 border counties in Yunnan Province from 2012 to 2014 were collected and analyzed by using Microsoft Excel 2010. Results From 2012 to 2014,a total of 1 558 malaria cases were report?ed in the 20 border counties in Yunnan Province,among which,1 336 were imported cases,accounting for 85.75%(1 336/1 558),and 222 were indigenous cases,accounting for 14.25%(222/1 558). The number of the imported cases in the above years took up 80.00%(544/680),89.10%(425/477)and 91.52%(367/401)of the total reported cases in the whole year,re?spectively. Among all the 1 336 imported cases,1 045(78.22%)were infected with Plasmodium vivax,284(21.26%)were in?fected with P. falciparum,3 were infected with P. malariae,3 were mixed infection and 1 was an unclassified case;2 patients died. And 95.58%of the cases were mainly infected in Myanmar(1 277 cases). Young and middle?aged adult of 20-40 years who worked overseas were the predominant(802 cases,60.03%)and most of the cases occurred from April to June of the year (679 cases,50.82%). Those cases mainly distributed in Tengchong(459 cases),Ruili(366 cases),Yingjiang(191 cases)and Mangshi(78 cases). Conclusions The epidemic situation of imported malaria is serious in the border region of Yunnan Prov?ince. Therefore,the surveillance system of malaria control needs to be well planned and managed to ensure timely case detection and prompt response at the elimination and post?elimination stage.

OBJECTIVETo probe the risk of colorectal polyp, colon and rectal carcinoma and the intake of NSAIDs.
METHODSCase-control study participants were from patients who underwent colonoscopy at different hospitals, the persons with the above disease was as cases, and those without the above diseases was as controls. Use of NSAIDs was assessed by interviewing the participants with a questionnaire which include a list of NSAIDs and related dietary and life style factors and family history.
RESULTSThere are 37 cases of colorectal polyp, 105 cases of colon carcinoma and 142 cases of rectal carcinoma and 66 controls. Adjusted for potential confounders, the risk of colorectal polyposis, colon carcinoma and rectal carcinoma were markedly reduced by NSAIDs. The OR values were 0.21 (95% CI 0.07-0.65, P = 0.007), 0.13 (95% CI 0.05-0.35, P < 0.001), 0.15 (95% CI 0.11-0.58, P < 0.001) respectively. The risk of the above diseases were also reduced markedly by aspirin, the OR values were 0.265 (95% CI 0.07-0.96, P = 0.044), 0.10 (95% CI 0.03-0.35, P < 0.001), 0.15 (95% CI 0.04-0.49, P = 0.002) respectively. The risk of colon carcinoma was also reduced by profen, with the OR being 0.11 (95% CI 0.02-0.64, P = 0.014).
CONCLUSIONSAspirin and other NSAIDs could reduced the risk of colorectal polyp, colon carcinoma and rectal carcinoma markedly. Aspirin was the most prospective chemopreventive agents for colorectal polyp, colon and rectal carcinoma for its capability of reducing the risk of cardio-cerebral vascular disease as well.
