The present study was to investigate whether peripheral NMDA receptors were involved in the persistent nociceptioninduced by subcutaneous (s. C. ) bee venom injection in the conscious rat by using quatitative pain scoring methods, a.c. Bee venom injection into one hindpaw resulted in a persistent, monophasic nociceptive response characterized by continuously flinching.lifting and licking the injected paw for more than I h. The non-competitive. NMDA receptor channel blockers, ketamine and ME-801, were administered s.c. 5 or 20 min after bee venom. Local ketamine injection produced a suppression of flinching reflex by 20. 90±2.88% and 45.76±13.9%, while that of lifting/bcking time by 39. 53±10. 05% and 59.94±5.53%, at doses of 25mmol/L and 50 mmol/L respectively without any motor disturbance, Local MK-801 resulted in an inhibition of flinching reflexby 22.84±3.12% and 49.53±5.35%. While that of lifting/licking time by 17. 49±5.67%and 53.49±3. 87%. At doses of 10μmol/L and 100 ,μmol/L respectively also with no motor disturbance. However, s. C. Administration of ketamine and MK-801 inior region symmetrical to the bee venom injection site on the contralateral hindpaw produced no change in the nociceptive behaviors, suggesting that the analgesic actions of keramme and MK-8Ol were not the result of systemic effects. The present resultsuggests that peripheral NMDA receptors are involved in the production of persistent pain.

BACKGROUND: Serum levels of high-sensitivity C-reactive protein (hs-CRP) can be used to predict cardiovascular injury.OBJECTIVE: To investigate the serum levels of hs-CRP in a rabbit model of atherosclerosis following repeated long-termexposure to positive acceleration and to predict the risk of cardiovascular injury.METHODS: Twenty-four New Zealand purebred rabbits were randomly divided into a positive acceleration group and a controlgroup. Rabbits in the positive acceleration group were exposed to +4 g rotation for 20 seconds with an acceleration of 1 g/s. Therotation interval was 5 minutes and totally three rotations were daily performed for 3 days per week. 0.5 g rotation was addedevery week, and by week 4, +6 g rotation was added, and the exposure lasted for 40 seconds.RESULTS AND CONCLUSION: Exposure to positive acceleration yielded significant effects on serum level of hs-CRP in rabbitswith atherosclerosis compared with before exposure (P < 0.01), but exposure time did not produce effects on serum level ofhs-CRP (P > 0.05). The interaction between exposure to positive acceleration and exposure time also did not produce significanteffects on serum level of hs-CRP (P > 0.05). Hyperplastic foam cells in the aortic tunica intima and the superficial layer of mediaincreased with the prolongation of exposure to positive acceleration. Repeated long-term exposure to positive acceleration maylead to a long-term high serum level of hs-CRP in rabbits.

Objective To explore the clinical characteristics of severe hand-foot-mouth disease in children and summarize nursing experience.Method The clinical data of 32 children with severe hand-foot-mouth disease were reviewed and analyzed retrospectively. Results After standard diagnosis and treatment,all cases were cured. The average stay in hospital was(8.2±1.6)d.Conclusion The close observation,prevention of infection,skin and oral nursing are of importance for promoting curative effectiveness and prognosis.

Relaxation and contraction factors influencing penile erection are produced and released by the central and peripheral nerves as well as intracavernosal sinus gap and vascular endothelial cells. Aging, diabetes, cardiovascular disease and spinal cord injury can influence these factors. Further researches of hyperbaric oxygenation (HBO) on the erectile dysfunction (ED) can provide some theoretical evidences for the clinical treatment of ED.

Objective To observe the clinical significance and variation of plasma B-type brain natriuretic peptide (△BNP) levels before and after treadmill exercise test (TET) in women with coronary heart disease(CHD). Methods Sixty-one women with suspected coronary heart disease were selected (except for heart failure, blood BNP levels were normal). All patients underwent coronary angiography, were divided into two groups, 25 cases in normal group and 36 cases in coronary heart disease group. Plasma BNP levels were measured before and after the TET test, and data were compared between two groups after one week.Furthermore, the levels of△BNP before and after TET in patients with different degrees of coronary artery lesions were compared. The diagnostic value of the levels of△BNP in coronary heart disease was evaluated by the re-ceiver operating characteristic curve (ROC). Results The plasma BNP level was significantly increased after TET (44.20± 14.53) than that before the test (32.82±10.72) in coronary heart disease group (P<0.01). There were significant differences in levels of△BNP before and after TET in patients with different degrees of coronary lesions. The levels of△BNP were sig-nificantly higher in multi-vessel disease group than those of single and double lesion group (P<0.05). The level of△BNP was significantly higher in double lesion group than that of single lesion group (P < 0.05). When the level of △BNP=7.3 ng/L, the sensibility value and specificity value for the diagnosis of CHD was 82.4%and 81.5%. The area under curve (AUC) was 0.900, and 95%confidence interval was 0.796-0.962. Conclusion The detection of△BNP before and after TET has an important clinical significance in the diagnosis and evaluation of coronary heart disease in women patients.

Objective To investigate the correlation between indexes of thrombelastogram (TEG) and hemorrhagic transformation (HT) after acute ischemic stroke.Methods The cases of acute ischemic stroke but not receiving early reperfusion therapy were recruited in our hospital from January to November 2016,and were divided into HT group and non-HT group.Their general clinical characteristics and TEG indexes were retrospectively analyzed,and comparison between two groups and multivariate Logistic regression analysis were performed.Results A total of 71 cases were enrolled and 11 of them were divided into HT group.The percentages of massive cerebral infarction and cardio-embolic stroke were significantly higher in HT group than those in non-HT group (P<0.05),whereas the levels of CI in HT group were significantly lower than thoes in non-HT group(P<0.05).Multivariate Logistic regression analysis showed that massive cerebral infarction (OR=13.172,95%CI:1.414-122.671) and CI(OR=0.554,95%CI:0.321-0.956) were independently correlated with HT(P<0.05).Conclusion CI is independently correlated with HT after acute ischemic stroke,and may be a potential predictor of HT.

Objective To investigate the effect of long-term intraocular retention of domestic perfluorocarbon liquid (PFCL) on morphology and histology of ocular tissues. Methods A total of 18 New-Zealand rabbits were randomly divided into 3 experimental groups, whose left eyes underwent intraocular injection with 0.3, 0.6, and 1.0 ml PFCL, respectively. All of the right eyes of the rabbits were in the control group. The morphological, electrophysiological and histological changes of the ocular tissue were observed 4, 8, and 12 weeks after the injection. Results No clinically significant retinopathy but only mild morphological changes were found in group 1 and 2, while obvious morphological and histological changes were found in group 3. Mild morphological and histological changes were found in all of the rabbits 4-8 weeks after the injection while significant ones were found 8-12 weeks after the injection. The results of electroretinography indicated a statistically significant decline of amplitude of b wave in group 3. Conclusions Long-term intraocular retention of few PFCL may cause mild histological changes but not affect the clinical function. Plentiful PFCL remains in eyes may lead to toxic reaction to the ocular tissue.
