Objective To observe the clinical therapial value of functional reconstruction with Botulinum Toxin A (BTA) on spasitic cerebral palsy. Methods Thirty-two patients were treated by Achilles tendon lengthening and anterior transfer of posterior tibial tendon.According to the spasticity of triceps surae muscle,all cases were arranged by BTA injection 2 months later after operation.Results From Jan.2000 to Jan.2009,thirty-two cases with equinovarus foot of spasticitical cerebral palsy were collected,the muscle strength of ankle dorsal extensor increased from 0-2 grades to 4-5 grades,there was significant difference between preoperational muscle strength and postoperational one.There was also significant improvement to adjust yarus degrees of ankle joint.the musclar tension of triceps muscle of calf decreased from Ⅱ-Ⅳ grades to Ⅰ-Ⅱ grades. Conclusion Anterior transfer of posterior tibial tendon corresponding with Botulinum Toxin A injection not only release muscle spasticity but also improve dorsal extending strength of ankle joint.The clinical effect of these methods was reliable on cerebral palsy.

Objective To investigate the effects of sevoflurane post treatment on cerebral ischemia-reperfusion injury in diabetic rats and non-diabetic rats.Methods Thirty-two male SD rats,aged 3.0-3.5 months,weighing 280-320 g,were divided into four groups by random number method (n =8):non diabetic ischemia reperfusion group (group NDC);diabetic ischemia reperfusion group (group DC2);non diabetic ischemia reperfusion group with the sevoflurane post-treatment (group NDS);diabetic ischemia reperfusion group with the sevoflurane post-treatment (group DS).The middle cerebral artery occlusion method and streptozotocin were used to establish the ischemiareperfusion injury model and diabetic model.2 h after ischemia and 24 h after reperfusion,the rats nerve defect scale was detected,the cerebral infarction volume was evaluated by TTC method,and Western blot method was used to detect angiogenin-1 (Ang 1) expression.Results Between the four groups of rats,nerve deficit score and infarct volume were significantly higher,Ang-1 protein relative expression was significantly lower in group DC than those in group NDC (P＜0.05);neural deficit score and infarct volume were significantly lower,Ang-1 protein relative expression was significantly higher in group NDS than those in group NDC (P＜0.05);nerve deficit score and infarct volume were significantly lower,Ang-1 protein relative expression was significantly higher in group DS than those in group DC (P＜0.05).Conclusion In the rats after cerebral ischemia reperfusion,diabetes could aggravate the nerve defect,increase the volume of cerebral infarction,reduce the expression of Ang-1;sevoflurane could reduce nerve defects,reduce infarct volume,increase the expression of Ang-1.The expression of Ang-1 and degree of injury after cerebral ischemia reperfusion in rats have relationship.

Objective:To assess the antibody persistence 3-5 years following vaccination of measles and rubella combined live-attenuated vaccine (MR) at 8 months of age and measles, mumps and rubella combined attenuated live vaccine (MMR) at 18 months of age.Methods:In 2016, 18-month-old children who were vaccinated with one dose of MR vaccine at the age of 8 months were recruited in Hebei Province as group 1; 4-, 5- and 6-year-old children who were vaccinated with one dose of MR vaccine at the age of 8 months and one dose of MMR vaccine at 18 months of age were recruited in Shanxi, Inner Mongolia and Beijing as group 2, group 3 and group 4, respectively. Serum samples were collected to detect IgG antibodies against measles, mumps and rubella by ELISA. Geometric mean concentrations (GMCs) of measles, mumps, and rubella antibodies were compared among groups by analysis of variance or non-parametric test. Seropositive rates were compared among groups by Chi-square test or Fisher′s exact test. Results:A total of 650 children were included in this study. Seropositive rates of measles, mumps and rubella antibodies 30 d after vaccination of 150 18-month-old children with one dose of MMR vaccine were 100%, 91.33% and 100%, respectively, and the GMCs were 1 846.87 mIU/ml, 299.91 IU/ml and 111.33 IU/ml, respectively. Seropositive rates of measles, mumps and rubella antibodies 3-5 years after vaccination one dose of MR vaccine at 8 months of age and one dose of MMR vaccine at 18 months of age were above 94%, 79% and 71%, respectively, and the GMCs were above 830 mIU/ml, 240 IU/ml and 31 IU/ml. No significant difference in the seropositive rates of the three antibodies was observed among groups 2, 3 and 4 ( P>0.05). There was no significant difference in the GMCs of measles or mumps antibodies among the three groups ( P>0.05), but the differences in the GMCs of rubella antibodies were statistically significant ( P=0.034). Conclusions:Measles, mumps and rubella antibodies persisted for 3-5 years without significant decrease after vaccination one dose of MR vaccine at 8 months of age and one dose of MMR vaccine at 18 months of age.

OBJECTIVETo observe the low-density lipoprotein cholesterol (LDL-C) target goal attainment rate and related factors in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).

METHODSFrom March 2011 to March 2012, a total of 832 ACS patients were retrospectively evaluated in the Cardiology Department of the First Affiliated Hospital of Dalian Medical University. The target goal attainment rate after PCI was defined as the percentage of patients reaching LDL-C goals recommended by The European Society of Cardiology (ESC) and the European Atherosclerosis Society (EAS) guidelines for the management of dyslipidemias (European guidelines) and Chinese guidelines on prevention and treatment of dyslipidemias in adults and Chinese guidelines on percutaneous coronary artery intervention treatment (Chinese guidelines). Multivariate logistic regression analysis was used to analyze the related factors.

RESULTSAccording to the European guidelines, the overall LDL-C goal attainment rates at 1 month and 9 months after PCI were 25.2% (210/832) and 22.2% (186/832), respectively. According to the Chinese guidelines, the overall LDL-C goal attainment rates at 1 month and 9 months after PCI were 46.5% (387/832) and 42.3% (352/832), respectively. In accordance with the Chinese guidelines, the multivariate logistic regression analysis showed that gender (females/males, OR = 0.650, 95%CI: 0.442-0.956), age ( ≥ 60 years/<60 years, OR = 0.628, 95%CI:0.464-0.850), hypertension (OR = 0.737, 95%CI: 0.547-0.994), prior myocardial infarction history (OR = 0.696, 95%CI:0.511-0.948), prior PCI history (OR = 0.575, 95%CI: 0.339-0.974) and baseline LDL-C levels ( OR = 0.155, 95%CI: 0.096-0.252) were independent risk factors that affected LDL-C goal attainment at 1 month post PCI. Moreover, the following parameters were the independent risk factors for LDL-C goal attainment at 9 months after PCI: prior myocardial infarction history (OR = 0.706, 95%CI:0.521-0.958), prior PCI history (OR = 0.565, 95%CI:0.334-0.957) and baseline LDL-C levels (OR = 0.176, 95%CI:0.110-0.282).

CONCLUSIONSCurrently, the LDL-C control rate is low in patients with ACS after PCI. The cholesterol lowering therapy should be individually strengthened for patients after PCI, especially in female patients, patients with aged ≥ 60 years old, hypertension, prior myocardial infarction history, prior PCI history and higher baseline LDL-C level.
