Conclusion Application of meridian point cosmetic therapy of TCM could facilitated the diagnosis and treatment by differentiation of symptoms and signs and thus improve the curing rate.

Objective To investigate the usefulness of Utstein template to guide the assessment and study of cardiopulmonary resuscitation (CPR) in our medical practice because it has been popularized in many countries since 1991.Methods A prospective observational study using Utstein CPR registry form to evaluate the epidemiological features and outcomes of 511 patients resuscitated in the emergency department.Results Of 511 CPR patients registered,higher cardiac arrest rates were observed in the group of patients aged 40- 70 years. In 511 CPR patients registered,preexisting chronic diseases were common including cardiovascular diseases ( 190,37.2％ ) cerebrovascular diseases (48,9.4％ ) and respiratory diseases (39,7.6％ ).Of them,173 cardiac arrest patients (33.9％) had underlying cardiac causes,such as acute myocardial infarction (AMI) found in 109 (21.3％) patients,and ventricular fibrillation witnessed during first cardiac monitoring in eighty ( 15.7％ ) patients.The restoration of spontaneous circulation (ROSC) rate and survival rate at discharge of in - hospital cardiac arrest (IHCA) patients were 47.0％ and 13.5％respectively,but 16.7％ and 4.7％ respectively in the out - hospital cardiac arrest (OHCA) patients (P ＜0.01,both ). Conclusions This study indicated that the cardiovascular diseases, cerebrovascular diseases,and respiratory diseases were the most common preexisting chronic diseases found in cardiac arrest patients.Myocardial infarct,stroke and trauma were the most common precipitation causes of cardiac arrest in the recruited patients.The rates of ROSC and survival at discharge were significantly higher in statistics in patients with IHCA than those in ones with OHCA.

Objective To determine the reliability of hand-held electronic dynamometer (HHD) tests for lower limb muscle strength measurement in children with spastic cerebral palsy (CP). Methods Twenty-eight children ( 15 boys and 13 girls; mean age 5 years 8 months) with different types of CP (2 with spastic quadriplegia,8 spastic diplegia, 6 hemiplegia, 1 triplegia and 1 monoplegia) , and at different functional levels ( 19 graded at gross motor function classification system level Ⅰ, 6 level Ⅱ, 2 level Ⅲ and 1 level Ⅳ ) were recruited from the Rehabilitation Center of the Children's Hospital of Fudan University. Standardized HHD protocols were used to measure the strength of their hip, knee and ankle muscles. The HHD test was performed by the same examiner twice with an interval of 10 min in between. The HDD test was also performed with 15 randomly selected CP children by 2 examiners with an interval of 10 min in between. The test-retest and inter-rater reliabilities of the HDD readings were determined by calculating the intra- and inter-class correlation coefficients. Results The HHD measurements showed fine testretest reliability ( ICC = 0.74-0.97 ) and inter-rater reliability ( ICC = 0.63-0.97 ) in measuring lower-limb muscle strength of children with spastic CP, with the highest test-retest reliability for the hip flexion, foot plantar flexion and knee extension muscle groups. The highest inter-rater reliability was achieved with the hip flexion and foot dorsiflexion muscle groups. Conclusions Standardized HHD testing of lower-limb muscle strength in children with spastic CP shows fine test-retest and inter-rater reliability. The HHD can reliably assess the lower-limb muscle strength of children with spastic CP.

Objective To observe the effect of acupuncture on ghrelin,estradiol (E2) and bone mineral density (BMD) in postmenopausal osteoporosis rats.Methods According to the random number table method,60 female Sprague-Dawley rats aged 3 months,were randomly divided into surgery group (40 rats) and sham group (20 rats).The osteoporosis model was established by bilateral ovariectomy.Three months after the operation,a significant decrease in BMD of lumbar vertebrae and femur of the model rats as measured by dual energy X-ray absorptionmetry against the sham group indicated successful establishment of the osteoporosis model.Then surgery group was randomly divided into a model subgroup,a acupuncture subgroup and an estrogen subgroup,with 10 rats in each subgroup.The acupuncture subgroup was treated with electroacupuncture,estrogen subgroup with subcutaneous injection of estradiol benzoate,sham group and model subgroup without any treatment.After 3 months of intervention all the rats were sacrificed,BMD of the lumbar vertebrae and femur was measured,ghrelin and E2 were determined.Results Serum ghrelin in acupuncture subgroup (399 pg/ml) and estrogen subgroup (276 pg/ml) were significantly lower (P ＜ 0.01) than that in model subgroup (546 pg/ml); serum E2 in acupuncture subgroup (128.02 pg/ml) and estrogen subgroup (182.89 pg/ml) increased significantly (P ＜ 0.05) than that in model subgroup (72.10 pg/ml) ;lumbar vertebrae BMD in acupuncture subgroup (0.212 g/cm2) and estrogen subgroup (0.231 g/cm2) increased significantly (P ＜ 0.05) than that in model subgroup (0.191 g/cm2),but in acupuncture subgroup the effect on improving the level of E2,ghrelin and lumbar vertebrae BMD was less than that in estrogen subgroup (P ＜ 0.05).Conclusions Acupuncture intervention can improve lumbar vertebrae BMD and serum E2 level of postmenopausal osteoporosis rat model,down regulate serum ghrelin level,but the overall effect of acupuncture is less than estrogen.

Objective To study the role of human MutS homolog 2 (hMSH2), a newly identified protein ligand that was recognized by Vγ9δ2 T cells , in innate anti-gastric carcinoma immunity .Methods Flow cytometry and laser confocal microscopy were used to identify hMSH 2 that ectopically expressed on gas-tric carcinoma cell line 803.An anti-hMSH2 antibody was used to block hMSH2 to evaluate its effects on the cytotoxicity of Vγ9δ2 T cells and their cytokines secretion .Subcellular distribution of hMSH 2 in gastric car-cinoma tissues was examined by tissue microarray immunohistochemistry analysis .Results Ectopic mem-brane expression of hMSH 2 was observed on 803 cells at a relatively high level .Vγ9δ2 T cells blocked with specific anti-hMSH2 antibody showed a decreased cytotoxicity and a reduced IFN-γbut an increased TNF-αsecretion.Ectopic expression of hMSH2 was found in various types of gastric carcinoma tissues at different stages.Enhanced expression of hMSH2 was detected in specimens collected from patients with chronic super-ficial gastritis.Conclusion Ectopically expressed hMSH2 served as a stress-induced endogenous ligand which could promote the cytotoxicity of Vγ9δ2 T cells against gastric carcinoma cells and enhance their IFN-γsecretion.hMSH2 played an essential role in innate anti-gastric carcinoma immunity .

Objective To identify the reliability and validity of Chinese version of expanded and revised Gross Motor Function Classification System (GMFCS E&R). Methods 101 children with cerebral palsy aged 6～18 from 2 special schools in Shanghai and Guangzhou participated in this study. The interrater reliability was identified by analyzing the assessment results among different raters, including rehabilitation doctors, physical therapists, teachers and parents. Gross Motor Function Measure (GMFM) was used as the criterion to identify the parallel validity. Results GMFCS E&R had good interrater reliability (ICC=0.79～0.91) as well as the parallel validity (Spearman rank correlation coefficient is -0.46～-0.86). Conclusion Chinese version of GMFCS E&R has good reliability and validity. It is suitable for children with cerebral palsy as the tool of function classification in China.

Objective To explore the characteristics of gross motor development in 1～6-year-old children with cerebral palsy at different levels. Methods 708 children (487 males and 221 females, age range: 1～6 years, from 6 rehabilitation centers in Shanghai) with cerebral palsy (CP) were assessed with Chinese version of Gross Motor Function Classification System （GMFCS） and Gross Motor Function Measure (GMFM). Distributions of GMFM scores at different GMFCS levels in children with cerebral palsy were analyzed. Results The GMFM-66 scores increased most in children with GMFCS Level Ⅰ, and more than 75% of them would be greater than 67 points in GMFM-66 score after the age of 48～50 months. The children with GMFCS Level Ⅱ～Ⅳ appeared similar increasing range of GMFM-66 scores in 1～6 years old. Less than 25% of the children at GMFCS Level Ⅱ would be greater than 67 points in GMFM-66 score before the age of 6 years, more than 50% of those at GMFCS Level Ⅲ would be less than 56 points, more than 75% of those at GMFCS Level Ⅳ couldn't exceed 46 points （except groups of 54～56 months and 66～68 months）. Compared with the children with other GMFCS levels, the GMFM-66 scores were always at very low level in children with GMFCS Level V, and trended to decrease with time after 5 years old. Conclusion The characteristics of gross motor development are different in children with cerebral palsy at different GMFCS levels.

Objective To analyze the content validity of Gross Motor Function Measure (GMFM) for cerebral palsy. Methods Concept contained in each item of GMFM was determined by 3 rehabilitation physicians or therapists who evaluated with GMFM for more than 2 years. All the concepts extracted were discussed in a meeting. The terms finalized were linked to the categories of International Classification of Functioning, Disability and Health Child and Youth version (ICF-CY) by 2 rehabilitation physicians who are familiar with the terms of ICF-CY according to the linking rules after discussion. Third party would intervene informally if there was a disagreement. The distribution of the ICF-CY categories involved were analyzed. Results 88 items from the GMFM linked to 27 categorise of 3rd level within 12 categories of 2nd level, belong to b7 Neuromusculoskeletal and Movement-related Functions and d4 Activities. 86 items linked to d4x, and 47 of then linked to b7x too. 2 items linked to b7x only. 16 items linked to the categories added to ICF-CY 16 times, involved 3 3rd level categories in a 2nd level category. Conclusion GMFM mainly focused on the activities in the framework of ICF-CY, especially the activities of changing and maintaining functional as well as the body posture and walking or moving. For the body function, the GMFM mainly focus on the support from arms.

Objective To investigate the related risk factors of contrast-induced acute kidney injury (CI-AKI)after cerebrovascular intervention. Methods The clinical data of 5423 patients performed cerebrovascular angiography and intervention at the Departments of Neurology and Neurosurgery,Guangdong People′s Hospital from January 2005 to December 2013 were analyzed retrospectively. The patients who underwent cerebrovascular angiography and intervention were evaluated and screened. A clinical history database was established. All the selected patients used iodixanol,an isotonic contrast agent. The occurrence of CI-AKI was used as an endpoint. The patients were divided into either a CI-AKI group or a non CI-AKI group. A multivariate Logistic regression model was used to analyze the risk factors associated with the occurrence of CI-AKI. Results A total of 4164 patients were finally enrolled,including 137 had CI-AKI. The incidence of CI-AKI was 3. 3%. The results of multivariate Logistic regression showed that age >60 years (OR,1. 965,95%CI 1. 244-3. 136),baseline estimated glomerular filtration rate (eGFR)<60mL/(min·1. 73 m2)(OR,4. 163,95%CI 2. 422-5. 873),diabetes (OR,3. 140,95%CI 1. 983-3. 902),and anemia (OR,1. 524,95%CI 1. 226 -3. 253)were the influencing factors for occurring CI-AKI after cerebrovascular angiography and intervention. Conclusion Chronic kidney disease (eGFR<60 mL/[min·1. 73 m2 ]),diabetes,anemia,and old age (age >60 years)are the independent risk factors for occurring CI-AKI after cerebrovascular angiography and intervention.
