OBJECTIVETo evaluate therapeutic effects of Rigidfix cross pins combined with Intrafix pins for the reconstruction of anterior or posterior cruciate ligament under arthroscopy.

METHODSFrom January 2009 to June 2010,34 patients with anterior or posterior cruciate ligament injuries were divided into two groups : group A and group B. There were 24 patients in group A, including 19 males and 5 females,with an average age of (31.83±9.57) years old. The patients in group A were treated with anterior cruciate ligament reconstruction under arthroscopy; Rigidfix cross pins and Intrafix pins were used to fix femoral and tibial side respectively. Among the 10 patients in group B, 8 patients were male and 2 patients were female, with an average age of (27.20+7.59) years old. The patients in group B were treated with posterior cruciate ligament reconstruction under arthroscope; Intrafix pins and Rigidifix cross pins were used to fix femoral and tibial side sepectively. The drawer test and Lachaman test were used to evaluate postoperative knee stability. All the patients were followed up at least 18 months. Lysholm and Tegner knee scores were used to evaluate the clinical therapeutic effects.

RESULTSAll the 34 patients were followed up, and the duration ranged from 18 to 26 months,with an average of (20.79±2.39) months. All the patients obtained good pain relief and knee stability. In group A,Lysholm scores significantly increased from 43.04±7.57 preoperatively to 85.41±4.68, 92.50±3.05, and 93.45±2.57 at 6,12, and 18 months postoperatively; Tegner scores significantly increased from 2.62±0.92 preoperatively to 7.45±1.14, 8.58±0.77, and 8.95±0.55 at 6, 12, and 18 months postoperatively. In group B,Lysholm scores significantly increased from 46.20±8.27 preoperatively to 86.40±5.14,90.40±2.67,and 92.00±3.85 at 6,12,and 18 months postoperatively ;Tegner scores significantly increased from 2.00±0.66 preoperatively to 7.10±0.99, 8.60±0.84, and 8.80±0.42 at 6,12, and 18 months postoperatively. There were no differences in Lysholm and Tegner scores between group A and B at different times during follow-up. Lysholm scores of all patients significantly increased from 43.97±7.79 preoperatively to 85.70±4.76,91.88±3.06,and 93.02±3.01 at 6,12,and 18 months postoperatively. Tegner scores of all patients significantly increased from 2.44±0.89 preoperatively to 7.35±1.09, 8.58±0.78, and 8.91±0.51 at 6,12,and 18 months postoperatively. During the follow-up period,there were no serious immunological rejection and complications.

ObjectiveTo investigate the effects of moxa smoke versus tobaccosmoke on autonomous behaviors and hippocampal expression of glial fibrillary acidic protein (GFAP) in apolipoprotein E gene knockout (ApoE-/-) mice.Method Thirteen 8-week-old C57BL/6 mice constituted a blank control group. Twenty-seven ApoE-/-mice of the same age were randomized into ApoE-/-model, moxa smoke and tobacco smoke groups. The tobacco smoke and moxa smoke groups of mice were exposed to smoke 5-15 mg/m3circumstances. Every group of mice was intervened in 20 min. daily, six days a week, for atotal of 12 weeks. A behavioral test was conducted in week 13. The animals were then sacrificed to take the materials. Hippocampal GFAP in the brain was measured by an immunohistochemical method.ResultAutonomous activities were significantly more in theblank group than in the model group (P<0.05) and significantly fewer in the tobacco smoke group than in the blank group (P<0.05). There was no statistically significant difference in autonomous activities between the tobacco smoke group and the model or moxa smoke group (P>0.05). Moving distance was longer in the moxa smoke group than in the model group (P<0.05). Standing-up number was smaller in the moxa smoke group than in the blank group (P<0.05). Integral optical density of GFAP immune reaction products in the hippocampus was significantlyhigher in the model group of mice than in the blank and moxa smoke groups (P<0.05). Hippocampal GFAP expression was significantly higher in the group of mice than in the moxa smoke and blank groups (P<0.05).Conclusion Moxa smoke can increase the excitability of central nervous system in mice and reduce hippocampal GFAP expression in a mice model of Alzheimer disease.

Objective To analyze the influencing factors of having clinical meaningful recanalization (CMR)after revascularization therapy in acute phase of ischemic stroke. Methods A total of 267 consecutive patients with ischemic stroke admitted to the Department of Neurology,Xuanwu Hospital, Capital Medical University and received intravenous thrombolysis or endovascular intervention in acute stage from March 2011 and March 2015 were enrolled retrospectively. CMR was used as a primary endpoint event. They were divided into either a CMR group (n = 92)or a non-CMR group (n = 175)according to whether they had CMR. The baseline data of the patients in both groups were compared by using the Rank sum test and Pearson Chi-Square test. A multivariate logistic regression model was established to analyze the independent influencing factor of CMR. Results The median (interquartile range)age of 267 patents was 60 (51 -69)years,and 69 of them were females (25. 8%);the median (interquartile range)time from onset to treatment was 250 (195 -305)min,and the median (interquartile range)NIHSS score was 10 (6 -15). The baseline NIHSS score,body mass index,blood glucose level,and proportion of diabetes of the CMR group were significantly lower than those of the non-CMR group (all P≤0. 05). The results of multivariate logistic regression analysis showed that the baseline NIHSS (OR,0. 93,95% CI 0. 88 -0. 98;P = 0. 01),intravenous thrombolysis (with respect to endovascular intervention)(OR,0. 35, 95% CI 0. 17 -0. 73;P = 0. 01),and baseline blood glucose (OR,0. 87;95% CI 0. 77 -0. 98;P =0. 02)were the independent negative predictors of CMR. Conclusion The baseline NIHSS,intravenous thrombolysis (with respect to endovascular intervention),and high blood glucose are the negative influencing factors for achieving CMR in the acute phase of ischemic stroke,suggesting blood sugar intervention and endovascular intervention in acute phase may contribute to the improvement of clinical prognosis.

Objective To explore the relationship between the degree of intraplaque neovascularization in carotid artery and the level of serum homocysteine.Methods Contrast-enhanced ultrasound were performed on 72 carotid atherosclerotic plaques of 48 patients.Contrast-enhancement within the plaque was categorizde as grade 1 to grade 3.The level of serum homocysteine were detected in the fasting state during the same period.Results According to the degree of contrast enhancement(grade 1 to 3),patients were divided into 3 groups.The more new vessels in plaque,the higher the level of homocysteine.The levels of homocysteine in three groups increased in turn.There were distinct differences among the three groups(F =18.49,P ＜0.05),and there was significant difference between every two groups (P ＜0.05).The linear correlation analysis showed that the level of homocysteine was positively correlated with the degree of carotid plaque enhancement (r =0.66,P ＜ 0.01).Conclusions Contrastenhanced ultrasonography could semi-quantitate new vessles in plaque.There was positive correlation between the degree of intraplaque neovascularization with the level of serum homocysteine.Combine with the level of serum homocysteine based on intraplaque neovascularization detected by contrast-enhanced ultrasound,the plaque stability could be more accurately evaluated.
