The Europe Stroke Scale (ESS), Barthel index (BI) and blood rheology were compared among these three groups.ResultsESS and BI score of group Ⅱ were higher than that of group Ⅰ, but lower than that of group Ⅲ. The recurrence rate and blood rheology index was similar in group Ⅰand Ⅱ, but higher than that of group Ⅲ.ConclusionBoth Xuesaitong Capsule and aspirin are effectivity on stroke in recovery phase, but it is better to take in both medicines.

OBJECTIVEThis study aims to evaluate the effectiveness of arthrocentesis on Wilkes III stage patients. Clinical examinations and magnetic resonance imaging (MRI) findings before treatment and six months after treatment were compared and analyzed.

METHODSA total of 137 outpatients diagnosed with temporomandibular joint internal derangement (TMJID) associated with Wilkes III stage through clinical examination and MRI findings from January 2013 to December 2013 were randomly included. All the patients were successfully treated with arthrocentesis. Moreover, all the patients accepted clinical and MRI examination before arthrocentesis treatment and six months after. Clinical examination included visual analogue scale and opening degree, whereas MRI examination included articular disc morphology and effusion in the upper compartments. Statistical analysis was performed using SPSS 20.0.

RESULTSResults showed that the average score of visual analogue scale six months after treatment was significantly lower than that before treatment (P < 0.05). The success rate was 78.1% (107/137). The rate of disc deformity after arthrocentesis treatment was higher than that before the treatment. By contrast, the positive rate of effusion after arthrocentesis was significantly lower than that before the treatment (P < 0.05). Bilaminar zone adaptive changes (disk-like) were found in seven cases (5.1%, 7/137) after treatment.

CONCLUSIONArthrocentesis could effectively relieve pain of the TMJID patients. Furthermore, MRI results indicated that arthrocentesis could significantly decrease articular effusion. Arthrocentesis was effective for the treatment of Wilkes III stage in the short term. Adaptive changes in bilaminar zone occurred in a few patients. However, serious disc deformity with the passage of time is a trend that has been observed.

Objective To observe the histopathological changes in the kidneys with stress reaction under +Gx loads in rhesus monkeys. Methods Nine male Rhesus macaques monkeys were randomly divided into four groups: control group animals were exposed to +1Gx/300s overload, and experimental groups 1, 2 and 3 animals were exposed to +15Gx/200s, +21Gx/165s and +21Gx/140s (3 animals in each group), respectively. Renal tissue was fixed with 10% buffered formaldehyde and paraffin sectioned, and histopathological changes were observed with microscope. Results In the experimental groups, glomerular congestion, and dilation of interstitial vessels with erythrocytic extravasation were found in both kidneys. Obvious cloudy swelling of the epithelial cells was also noted in the renal tubules. The degree of renal damage was significantly correlated with the increase in +Gx loads. There was no obvious change in the control group. Conclusion Overload gravity can induce significant injury to the kidney in the monkeys. There is a significant correlation of the degree of renal damage with the level of +Gx load.

Objective: To investigate the effect of alendronate on serum total alkaline phosphatase (AKP) and bone specific alkaline phosphatase (BAP) in the elderly female patients with postmenopausal osteoporosis and explore their correlations.Methods: A retrospective study was performed.Totally 286 elderly female patients with postmenopausal osteoporosis were divided into two groups(according to AKP levels before the treatment of alendronate): the normal AKP group (n=245) and the elevated AKP group (n=41).Raised AKP of all the patients in the elevated AKP group was not associated with hepatobiliary problems.The changes of AKP and BAP levels were analyzed after the treatment of alendronate.The correlations between BAP and AKP levels before and after the treatment of alendronate were analyzed, as well as between the changes in AKP (ΔAKP) and BAP (ΔBAP) levels.Results: AKP and BAP tended to be higher in elderly patients.BAP levels in the normal AKP group were higher than those in the elevated AKP group (P＜0.05).BAP was signicantly correlated with AKP both before and after the treatment (P＜0.05), as well as the correlation between ΔAKP and ΔBAP (P＜0.05).Conclusion: AKP and BAP both tend to increase with age.In elderly female patients with postmenopausal osteoporosis and elevated AKP associated with non-hepatobiliary problems, alendronate treatment can lower AKP levels, and the decrease is strongly correlated with the decrease in BAP.

BACKGROUND:Coenzyme Q10 participates in the electron transport of respiratory chain and possesses antioxidant, anti-apoptotic and anti-inflammatory properties. It has achieved good outcomes in cardiovascular disease, diabetes and cancer. Coenzyme Q10 may also have a certain application value in the fields of diabetes and periodontitis. OBJECTIVE:To observe the effect of coenzyme Q10 on the expression of interleukin-17 and interleukin-23 in gingival tissue of type 2 diabetic rats with periodontitis.METHODS:Forty-eight healthy male Wistar rats were randomly divided into 3 groups: control, periodontitis+ diabetes+physiological saline and periodontitis+diabetes+coenzyme Q10. Rats in the control group were fed with normal diet and water. Rats in the periodontitis+diabetes+physiological saline and periodontitis+diabetes+ coenzyme Q10 groups were subjected to induction of periodontitis using the method of silk ligation and type 2 diabetes by feeding a high-fat and high-sugar diet and intraperitoneal injection of streptozotocin. After successful modeling, rats in the periodontitis+diabetes+coenzyme Q10 group were intragastricaly administered coenzyme Q10 for 8 successive weeks. Rats in the periodontitis+diabetes+physiological saline group were administered equal amount of physiological saline. At the end of 2nd, 4th and 8th weeks after drug administration, four rats were randomly selected and sacrificed. The expression levels of interleukin-17 and interleukin-23 in gingival tissue were detected by immunohistochemistry. RESULTS AND CONCLUSION: At the end of 8th week, interleukin-17- and interleukin-23-positive expression in the periodontitis+diabetes+physiological saline group was significantly higher than that in the periodontitis+ diabetes+coenzyme Q10 group (P < 0.05). Coenzyme Q10 can reduce the expression levels of interleukin-17 and interleukin-23 in gingival tissue of type 2 diabetic rats with periodontitis, and aleviate periodontal tissue inflammation of type 2 diabetic rats with periodontitis.

Objective To explore the relationship between the test of drug-induced electroencephalography(EEG) and epilepsy.Methods324 patients with epilepsy were randomly divided into 2 groups, the benadrly group(n=162) and chloral hydrate group(n=162) as control. EEG was examined by evoking during sleep to observe epileptiform discharge and which stage of non-rapid eye movements (NREM) epileptiform discharge occurred more frequently.ResultsThe epileptiform discharge was 31.61% in benadrly group, and 18.52% in chloral hydrate group. There was significant difference between the two groups (P<0.01). The detection rate of epileptiform discharge at the stage I～II of NREM was significantly higher in benadrly group (83.7%) than in chloral hydrate group(63.3%)(P<0.05), which suggested that epileptiform discharge frequently occurred at the stage I～II of NREM.ConclusionBenadrly is superior to chloral hydrate in the test of drug-induced EEG of epilepsy.
