Objective To study the comparison of the therapeutic effect of Ultrasound guided and freehand botulinum toxin type of the treatment in children with cerebral palsy.Methods From March 2014 to September 2016,98 cases of children with cerebral palsy in our hospital by injection of botulinum toxin were treated.According to the way of injection,the children were divided into ultrasound group and free group(n =49).They were respectively gave botulinum toxin injection by guided Ultrasound guided and freehand ultrasound injection of hotulinum toxin injection.The amount of two groups of children was 3U/kg.Children muscle spasm degree of before and after treatment was assessed by modified Ashworth spasm scale.And exercise capacity of children before and after treatment was assessed by the gross motor function rating scale.The follow-up time was 3 months,the clinical curative effect of two groups of children was observed.Results The total efficiency of ultrasound guided group (98.0％) was significantly higher than the free group (79.6％),with statistically significant (P ＜ 0.05).Both groups before and after treatment in children with Ashworth score and GMFM score were significantly improved,with statistical significance (P ＜ 0.05).Ashworth score and GMFM scores of ultrasound guided group were significantly better than the free group,with statistically significant (P ＜ 0.05).Conclusion Botulinum toxin injection in the treatment of cerebral palsy children can effectively solve the spastic problem.Treatment of children with cerebral palsy by injecting botulinum toxin with ultrasound guided injection of botulinurn toxin is better than manual injection of botulinum toxin.

BACKGROUND:Previous studies demonstrated that ischemia can be compensated by establishing collateral circulation and microangiogenesis,and exercise training can ameliorate blood supply of ischemic lower limb.However,whether exercise training accelerate establishment of collateral circulation remains poorly understood.OBJECTIVE:To explore the mechanism of exercise training on accelerating microangiogenesis of rat ischemic lower limb.METHODS:Sprague-Dawley rats were randomly divided into the exercise training,model and sham-surgery groups.All animals were established left lower limb ischemia models except those in the sham-surgery group.Rats in the exercise training group were forced running 30 minutes per day at 1 week after model preparation and those in other groups were performed daily activities.The adductor of ischemic lower limb was obtained for the examination of microvessel density and the expressions of vascular endothelial growth factor and basic fibroblast growth factor.Simultaneously,bone marrow-derived endothelial progenitor cells were harvested for detection of microangiogenesis.RESULTS AND CONCLUSION:Number of endothelial progenitor calls,expressions of vascular endothelial growth factor and basic fibroblast growth factor,as well as microvessel density of the exercise training group was obviously greater than those in the model and sham-surgery groups(P<0.01).Compared with the model and sham-surgery groups,in vitro vasculogenesisof bone marrow-derived endothelial progenitor cells in the exercise training group was increased(P<0.05).These findings demonstrated that lower limb ischemia increases microangiogenesis,and exercise training enhances this effect.

Objective To discuss the rehtionship between lipoprotein [Lp (a)],homocysteine (Hcy) and coronary artery disease (CAD) in men.Methods Two hundred and twenty-two male patients admitted for coronary angiography were classified into CAD positive group (111 cases) and CAD negative group (111 cases).The clinical data and plasma Hcy and Lp(a) levels were recorded in both groups.Logistic regression analysis was used to analyze males CAD risk factors.Results Lp (a) ≥0.3 g/L was a risk factor for CAD (OR =5.04,95％ CI 1.88-13.51,P =0.001),whereas Hcy was not related to CAD (OR =1.35,95％ CI 0.63-2.89,P =0.443).However,when both factors were considered together in an interaction model,plasma high Hcy and high Lp (a) levels were risk factors for CAD (OR =11.54,95％ CI 2.62-45.61,P=0.003).Conclusion Plasma Lp (a) and Hcy levels may increase the incidence of male CAD process.

Objective To observe the expression and relevance of human papillomavirus L1 (HPVL1)capsid protein and tumor suppressor gene p16~4A in cervical lesions.Methods The expression of HPVL1 capsid protein and p16INK4A in liquid-based cytology specimens and organization from 210 cases infected with HPV virus were detected by Max-vision immunohistochemistry method.Results In different grade of liquidbased cytology specimens,the positive rates of HPVL1 capsid protein had statistic difference (x 2 =70.50,P ＜ 0.005).The rate in LSIL couples was 68 ％ (34/50),which was the highest in all couples.The positive rates of tumor suppressor gene p16INK4A were increased gradually.In SCC couples,the positive rates was 100 ％(30/30),which was the hishest.In LISL couples,the rate of HPVL1+ p16INK4A-was 32 ％ (16/50),which was the hishest.In SCC couples,the rate of HPVL1-p16INK4A+ was 100 ％ (30/30),which was the highest.In orgnizational specimens,the positive rates of HPVL1 capsid protein in cervical intraepithelial neoplasia had statistic difference (x2 =54.37,P ＜ 0.005).The rate in CIN Ⅰ group was 60.4 ％ (32/53),which was the highest.The positive rates of tumor suppressor gene p16 were increased gradually.In cervical cancer group,the positive rate was 100 ％ (28/28),which was the highest.In CIN Ⅰ group,the rate of HPVL1+ p16INK4A-was 45.3 ％ (24/53),which was the highest.In cervical cancer couples,the rate of HPVL1 (-) p16INK4A(+) was 100 ％ (28/28),which was the highest.Conclusion Detection on the expression of HPVL1 capsid protein and tumor suppressor gene p16INK4A can diverse different levels of cervical lesions and separate cases from aggravated or self-healing,to avoid over-treatment or misdiagnose.

Objective To study the relation between the level of central N-methyl-D-aspartate (NMDA) receptor system and the degree of morphine withdrawal syndrome in rats. Methods We established the morphine-dependence model in rats,stimulated addiction by naloxone after intracerebroventricular injection of glutamic acid/ketamine/MK-801,and then observed the effects on rats' morphine withdrawal syndrome. Results Glutamic acid significantly raised the behavior scores of teeth chattering,wet shakes,writhing,penis licking and weight loss,while ketamine and MK-801 decreased the scores. Conclusion Changes of central NMDA system obviously affect morphine withdrawal syndrome in rats,which may be useful laboratory evidence in selecting new no-opiod therapeutic medicine for morphine resistance and addiction.

The level of lipid peroxides (LPO)and copper-zinc containing superoxide dismutase(SOD-I) in the gastric mucosa and serum was determined in 141 samples from 25 patients after conventional subtotal gastrectomy (11 cases of Billroth I and 14 cases of Billroth Ⅱ and 11 patients after pylorus and antroseromuscular flap preserving gastrectomy (PAFPG).Those of 11 normal subjects were examined likewise to serve as control.It was found that;1.The average LPO level was much higher and the average SOD-I level much lower in the gastric mucosa after conventional subtotal gastrectomy especially the Billroth type Ⅱ than in those after PAFPG.2.In 36 specimens of stump mucosa,the average LPO level was significantly higher in the tissue around the anastomotic ring than in that of the body of the stump;no marked difference of SOD-I level between the 2 was revealed.3.The LPO value in the stump mucosa was positively correlated to and the SOD-I value negatively correlated to the pH value of gastric juice.Thess findings suggest that the reaction of oxygen free radicals in the stump-mucosa may be influenced by the intragastric pH or by the type of digestive continuity reconstruction,and that the reaction of free radicals specially lipidperoxidation may play a role in the pathogenesis of the lesions in the anastomotic stoma.

0.05).Large amounts of E.coli and intestinal aerobics such as Veillonella spp.,Bacteriodes fragilis,and Clostridium spp.were detected in patients with B-Ⅰ and B-Ⅱ especially the latter but not found in those with PAFPG.These findings suggest that intragastric bacterial overgrowth,can exist in the hypoacidic stumps in the first one to three years afte conventional gastrectomy especially after B-Ⅱ,no such occurrence is found in those after PAFPG since it only moderately reduces the intragastric acidity.

Objective To investigate the association of cytotoxic T lymphocyte associated antigen 4 (CTLA 4) gene polymorphism with type 1diabetesmellitusandautoimmunethyroiddiseases. Methods The A/G phenotype at position 49 of the CTLA 4 gene exon 1 was determined by PCR RFLP method in 33 classic type 1 diabetes patients, 57 latent autoimmune diabetes in adults (LADA) patients, 122 autoimmune thyroid disease patients and 84 healthy control subjects of Chinese Han. Results The frequency of the CTLA 4 G phenotype was significantly higherintype1diabetespatientsthanthatincontrol subjects (55.6% vs 36.9%, P=0.0005). Neither the presence nor the absence of G allele influenced the occurrence of islet autoantibody (ICA) and glutamate decarboxylase antibody (GADA). The strong association of the CTLA 4 G allele with AITDs was showed in our study (66.4% vs 36.9%, P
