AIM: To compare the effectiveness of botulinus toxin of type A and complete resection of the periorbital muscle on idiopathic blepharospasm.
● METHODS: Patients with idiopathic blepharospasm and having undergone either of two procedures from Dec. 2010 to Jun. 2015 were selected ( 60 patients ) . Among them, group A (30 patients, 60 eyes) underwent botulinus toxin of type A, group B (30 patients, 60 eyes) underwent complete resection of the periorbital muscle.
●RESULTS: ln group A, the patients with complete response, obvious response, partial response, and no response were 36(60. 0%), 20(33. 3%), 2(3. 3%) and 2 (3. 3%) cases respectively. ln group B, the patients with complete response, obvious response, partial response, and no response were 16(26. 7%), 24(40. 0), 12(20. 0%) and 8 ( 13. 3%) cases respectively. The difference was statistically significant ( Z = - 2. 968, P = 0. 003 ). The relapse rate of group A and group B were 93. 3% and 20. 0% after 6mo, the difference was statistically significant (χ2=32. 851, P<0. 001).
●CONCLUSION: The botulinus toxin injection of type A is effective for idiopathic blepharospasm. But recurrence rate is high after 6mo. Complete resection of the periorbital muscle have long-term efficacy for idiopathic blepharospasm. It′s a supplementary therapy after idiopathic blepharospasm recurrence.

Objective To investigate the changes of serum high sensitive C-reactive protein(hs-CRP) level in patients with acute cerebral infarction(ACI),and the relationship between serum hs-CRP level and ACI severity as well as subtypes according to Chinese Ischemic Stroke Subclassification(CISS)criteria. Methods The serum hs-CRP level in 256 patients with ACI and 196 normal controls were measured. The degree of nervous function defect in patients with ACI was assessed by the United States National Institutes of Health Stroke Scale ( NIHSS ) score. All patients were classified into five major ischemic stroke subtypes based on CISS criteria. Logistic regression analysis was applied to analyze the risk factors of ACI. Results The serum hs-CRP level in patients with ACI and control group were(4. 69 ± 2. 58)mmol/ L and(2. 13 ± 1. 79)mmol/ L,and the difference between groups was significant(t = 12. 439,P = 0. 000). The hs-CRP in patients with severity ACI (147 cases)were(5. 89 ± 4. 15)mmol/ L,significantly higher than that in patients with mild ACI,and the difference between groups was significant((2. 11 ± 1. 45)mmol/ L,t = 10. 230,P = 0. 000)). As for subtype ACI,the case of the large artery atherosclerosis subtypes was 106( 41. 57% ),highest than any other subtypes. The hs-CRP level of large artery atherosclerosis was(7. 01 ± 3. 12)mmol/ L,higher than that of control group( P = 0. 000). The logistic regression analysis showed that many factors were related to ACI including total cholesterol,homocysteine and high sensitive C-reactive protein( OR = 0. 324,0. 749,0. 809;P< 0. 05). Conclusion The serum hs-CRP level in patients with ACI increase significantly,and relate to the degree of neural function defect. The level of hs-CRP of large artery atherosclerotic stroke is the highest. The change of serum hs-CRP is very valuable to estimate the severity of ACI.

Objective To discuss the application of prospective risk nursing measures in reducing the occurrence of postoperative local hematoma at femoral artery puncture site. Methods A total of 605 patients receiving femoral artery puncture for interventional management were collected as the control group , and 322 patients were used as the intervention group. The risk factors causing postoperative local hematoma at femoral artery puncture site in the control group were recorded, and based on which risk estimation survey table was designed. According to risk estimation survey, the prospective intervention measures, including risk assessment, standardization of professional training, individual health education, the improvement of care appliance, etc. were carried out for the patients of the intervention group. The occurrences of postoperative local hematoma at femoral artery puncture site were recorded and the results were compared between the two groups. Results No statistically significant differences in demographic and clinical data existed between the two groups. However, the incidence of hematoma in the intervention group was significantly lower than that in the control group (χ2 = 4.652, P < 0.05), although the difference in the severity of hematoma was not significant between the two groups. Conclusion The use of prospective risk nursing measures can effectively reduce the incidence of postoperative hematoma at femoral artery puncture site.

Objective To investigate the pathogenesis of gallbladder chaotic dynamics after partial gastrec-tomy. Methods 140 cases operated by partial gastrectomy after 6 months were randomly examined, they in-cluded one group of 40 cases by Billroth type and the other 100 cases by Eiselsberg type. The ultrasonograph was applied to evaluate the function of gallbladder dynamics and radio-immunity method to determine the content of CCK at the time of having no food and 30 minutes after med. Results BV and RV of Eiselsberg group were bigger than Billroth Ⅰ obviously P<0.05. Gallbladder contraction rate displayed not well obvi-ously as too. The plasm level of CCK had no manifested distinctions in empty stomach cases of the 2 groups, but the increasing gradient plasm level of CCK in Billroth Ⅰ exceeded Eiselsberg type. Conclusions The pathogenesis of gallbladder chaotic dynamics after partial gastrectomy was correlated with the alterative type of partial gastrectomy, the reduction of CCK plasm level, the damage of anterior vagal trunk hepatic branches during the operations and so on led to the disorder of gallbladder emptying and induced cholecystolithiasis.

M2e gene of three copies for H5N1 subtype AIV was synthesized and fused with human mycobacterium tuberculosis hsp70 gene.The fused gene was cloned into the prokaryotic expression vector to get pET-3M2e and pET-3M2e-hsp70.Recombinant protein r3M2e and r3M2e-hsp70 were successfully expressed induced with IPTG and purified with Ni2+-NTA collumn.Following that,the immunity of the recombinant protein was analysized with Western blot.20-day-old AIV non-immunized chickens were vaccined with r3M2e and r3M2e hsp70,at the same time,Trx and KLH-M2e inoculated chickens were served as vector and positive controls.Two weeks after the primary vaccination,every group was boosted with the same vaccine as in the primary vaccination.The humoral immunity of the vaccined chickens was evaluated with antibody detection against M2e,cytopathic suppression test,and indirect fluorescence assay.The cellular immunity was estimated according to lymphocyte subtype analysis with flow cytometry and M2e specific cytokine detection.Four weeks after the boost vaccine,all groups were challenged with 100EID50 AIV of H9N2 subtype,and the virus from swabs was detected with Real-time PCR.Results indicated that r3M2e hsp70 vaccined chicken developed the better humoral and cellular immune response,also,made a better performance compared with r3M2e vaccined group in virus challenge.

· Vascular endothelial growth factor is indispensable inducing factor in retinalangiogenesis. After the retinal neovascularization of proliferative diabetic retinopathy ( PDR ) patients, it can cause fibrovascular membrane formation, epiretinal membrane fibrosis increased, resulting in traction retinal detachment with further aggravate the condition. The recent research suggests that cytokines promote fibroblast proliferation, movement, adhesion, and secretion of extracellular matrix functions in the diabetic state of the environment changes to profibrogenic state, resulting in the accumulation and fibrosis of extracellular matrix. This paper reviewed the status quo of the correlation between vascular endothelial growth factor and fibrosis-related cytokine.

Objective To investigate the clinical features,treatment response and prognosis in children with Takayasu′s arteritis(TA) in order to improve the understanding of TA.Methods A retrospective study of 10 children with TA was performed.All of them were admitted and diagnosed in Peking University First Hospital from Jan.1998 to Oct.2008.The clinical features,laboratory tests,imaging modalities,treatment response and prognosis were all collected and evaluated.Results There were 3 boys and 7 girls in the 10 patients with TA,and the ratio of male to female was 12.3.The onset was from 4 months to 9 years old,with average age at 5.5 years old.The average duration of diagnosis was 7.6 months.The incidences of hypertension,vascular bruits,albuminuria,convulsion were present in 100%,100%,70% and 40%,respectively.The clinical types included typeⅡ(60%),type Ⅲ(10%) and type Ⅳ(30%).The acute phase inflammatory indices of activity such as erythrocyte sedimentation rate(ESR),C-reactive protein(CRP) and white blood cell(WBC) were not evidently increased.Tuberculosis infection was found in 6 out of 10 patients and anti-tuberculosis treatment was performed.Six patients were treated with steroids and 3 cases of them were also given immunosuppressives cyclophosphamide or methotrexate.Three of the 10 patients received anti-hypertensive and vasodilator.Two patients received percutaneous translurminal angioplasty and 1 patient received nephrectomy.One patient died of renal failure,heart failure and shock.Conclusions The patients with TA had high prevalence of tuberculosis infection,diagnosis as often late because of lack of specific clinical features at the acute inflammatory period.When organic ischaemia occurred,treatment response was usually unsatisfactory.Patients with multi-systemic and multi-viscera lesions should have comprehensive examination,especially for those with hypertension,pulseless and vascular bruits,in order to rule out TA.Early ultrasonography,computed tomography and magnetic resonnance image methods are valued in eariler diagnosis and they are the key factors to improve prognosis.
