It is very important to have a clear and widely accepted definition and classification for clinical diagnosis, rehabilitation, research and social support of children with cerebral palsy, as well as in establishing a regional, national and global monitoring database. There are some new changes about the definition, clinical types and function classification of cerebral palsy recently domestic and abroad, which pay more attention to assessments on function and participation in daily life.

Based on the community-based and family-centered concepts, the Chain Rehabilitation Services for children with cerebral palsy (CP) integrates all kinds of social resources to build the early screening network and community rehabilitation centers, and to enhance the integration of rehabilitation and educational services. This chain model makes it possible to coordinate the related institutes to provide better services for children with CP. Better services and better systematic management of children with CP in Shanghai and surrounding areas has also been achieved through this project.

BackgroundHigh myopia is one of leading causes of blindness,so far the pathogenesis remains unclear.Two single-nucleotide polymorphisms (SNPs) of rs6885224 and rs12716080 in CTNND2 gene were recently found to be associated with high myopia in Singaporean Chinese.But whether these SNPs are related with the pathogenesis of high myopia in Han Chinese is worth studying,Objective This study was to investigate the relationship between the genetic variations of the CTNND2 gene and high myopia in Han Chinese.MethodsA case-controlled association study was designed.Nine hundred and thirty-three individuals with high myopia and 1227age- and gender-matched normal subjects were included in this study.The 5 ml of periphery blood was obtained from all subjects for the extraction of genomic DNA.The target DNA was amplified using PCR and purified by the SNaPshot method.Four SNPs rs12716080,rs917012,rs6885224 and rs16901340 in the CTNND2 gene were genotyped.This study was approved by the Ethic Committee of Sichuan Provincial People Hospital.Written informed consent was obtained from each subject before his/her enrollment.Results The frequencies of the genotypes rs6885224,rs12716080,rs917012,rs16901340 SNPs were in Hardy-Weinberg equilibrium (HWE) ( P=0.181,0.085,0.732,0.313,0.264,0.663,0.084,0.196).There were no significant differences in genotypes frequency distribution ( in turn P =0.654,0.406,0.828,0.403 ) and allele frequency distribution of the CTNND2 gene ( in turn P =0.377,0.209,0.743,0.198) between the high myopia group and normal control group.The haplotypes (TA and GA)frequencies of rs12716080 and rs917012 in the high myopia group were significantly different from those of the normal control group(TA:0.784 vs.0.719;GA:0.087 vs.0.136) (x2 =6.115,P=0.013 ;x2 =6.634,P=0.010),but those of GG were similar between the high myopia group and normal control group ( 0.123 vs.0.143,x2 =0.889,P =0.346). ConclusionsThe SNPs rs12716080,rs917012,rs6885224 and rs16901340 in CTNND2 gene were not responsible for high myopia,however,the haplotypes of rs12716080 and rs917012 are susceptible for high myopia in Han Chinese.

Objective To evaluate the effects of different doses of dexmedetomidine on atrioventricular node (AVN) conduction function in the healthy volunteers.Methods Sixteen healthy volunteers of both sexes,aged 18-30 yr,with body mass index of 19-26 kg/m2,were included in the study.Dexmedetomidine was infused in a loading dose of 1.0 μg/kg over 10 min,followed by an infusion of 0.5 μg · kg-1 · h 1 for 50 min (Dose Ⅰ);1-2 weeks later,dexmedetomidine was infused in a loading dose of 1.5 μg/kg over 10 min,followed by an infusion of 0.75 μg · kg-1 · h-1 for 50 min (Dose Ⅱ).Before infusion of dexmedetomidine (T0) and at 15 and 35 min of infusion (T1.2),AVN Wenckebach point,AVN 2 ∶ 1 block point,AVN relative refractory period (AVNRRP),and AVN effective refractory period (AVNERP) were measured.Results AVN Wenckebach point and AVN 2 ∶ 1 block point were significantly decreased,and AVNRRP and AVNERP were significantly prolonged at T1,2 compared with those at T0 (P＜0.05).Compared with Dose Ⅰ,AVN Wenckebach point at T2 and AVN 2 ∶ 1 block point at T1,2 were significantly decreased,and AVNRRP and AVNERP were significantly prolonged at T1,2 in the subjects receiving Dose Ⅱ] (P＜0.05).Conclusion Dexmedetomidine can inhibit AVN conduction function in the healthy volunteers,and the inhibitory effect is enhanced with the increasing doses.

Objective To explore the application of gastric(enteric)-pharyngeal anastomosis for cervical esophageal carcinoma. Methods The clinical data of 12 cases with surgical management of cervical esophageal carcinoma were retrospectively analyzed. Results The resectability of cervical esophageal carcinoma was 100%,no case complicated with pharyngeal fistula.Swallowing function of all cases was in a good state.The overall follow-up was 1 to 7 years,among them 9 surviving,3 dead.The surviving 5 cases are over 3 years,the ongest beyond 7 years. Conclusions Gastric(enteric)-pharyngeal anastomosis is a good primarily rehabilitating method of the cervical esophageal defect after surgical treatment of cervical esophageal carcinoma.

In order to improve the production of agro-antibiotic 2-16,the producing strain(Streptomyces ahygroscopicus var.huangshanensis) was treated by protoplast regeneration,ultraviolet radiation,NTG mutagenesis and low energy C~(+) ion implantation.At last,a high-yield strain No.515 was obtained.The production of ~()No.515 was increased by 223.10%.By using Plackett-Burman design and Response Surface Analysis provided by SAS software,the cultivation condition of No.515 was optimized.The amount of agro-antibiotic 2-16 was increased by 38.53% when the strain No.515 was cultivated in the optimum medium instead of the initial one.

Objective To investigate the development and the risk factor of hip dislocation about children with cerebral palsy. Methods 90 children with cerebral palsy were divided with Chinese version of Gross Motor Function Classification System （GMFCS） and type of cerebral palsy. Their femoral head migration percentage was measured. Results The quadriplegia children were in the biggest risk of hip dislocation, hemiplegia children were the minimum; GMFCS Ⅰ children were in the lowest risk of hip dislocation, GMFCS Ⅴ children were the highest. Conclusion The abnormal development of the hip is correlative with the type of cerebral palsy and motor function in spastic cerebral palsy children.

In Europe Registration Management for Cerebral Palsy (CP) has been widely carried out, which collects various related information and systematically manages the rehabilitation of children with CP by uniform database. Chinese Registration Management for Cerebral Palsy fitted with Chinese situations should be established as soon as possible which will benefit the following: to provide more samples for scientific research on cerebral palsy; to promote social awareness and attention for CP children by multiple side participation; to help policymaker to plan more suitable policies for CP children and their families. The main problems needed to resolve are unification of the diagnosis, clinical types and function classification of cerebral palsy.

OBJECTIVETo observe the effects of Shensu II Recipe on the renal function, mesangial extracellular matrix (ECM) accumulation, the expressions of transforming growth factor-beta1, (TGF-beta1), and plasminogen activator inhibitor-1 (PAI-1) in the focal segmental glomerulosclerosis (FSGS) rats.

METHODSFSGS SD rat model was induced by injecting adriamycin. They were randomly divided into the model group, the Western medicine group, and the Chinese medicine group according to body weight. Besides, another 12 rats was taken as the blank control group. Of them, benazepril (0.33 mg/100 g) was given to rats in the Western medicine group by gastrogavage, while Shensu II Recipe (3.5 g/100 g) was given to rats in the Chinese medicine group by gastrogavage. Normal saline was given to rats in the control group and the model group by gastrogavage. Six rats died during the experiment process, among which, one in the control group, two in the model group, one in the Western medicine group, and two in the Chinese medicine group. The changes of 24 h urinary protein (24 hU, pyrogallol red method), blood urea nitrogen (BUN, urease method), serum creatinine (SCr, enzymatic assay of creatinine), serum total protein (TP, biuret colorimetry), serum albumin (ALB, bromocresol green colormetry) were detected. The pathomorphological changes of the glomerulus were observed. Fibronection (FN), collagen IV (Col IV), glomerulus sclerosis index (GSI), ECM/glomerulus area (GA), expressions of TGF-beta1, and PAI-1 were determined by semi-quantitative analysis.

RESULTSAt the end of the 12th week, improvement was shown in the Chinese medicine group (24 hU: 38.55 +/- 2.49 mg; BUN:10.87 +/- 1.78 mmol/L; SCr: 51.70 +/- 1.50 micromol/L; TP: 68.28 +/- 2.31 g/L; and ALB: 42.43 +/- 1.95 g/L). The pathomorphological observation showed that the development of glomerulosclerosis (GS) was significantly slowed down. Semi-quantitative analysis showed significant difference when compared with the model group (GSI: 1.68 +/- 0.33 grade; ECM/GA: 7.11% +/- 2.46%; FN: 4.15% +/- 1.55%; Col IV:1.47% +/- 0.48%; TGF-beta1:19.70% +/- 5.05%; PAI-1: 22.57% +/- 10.65%) ( P < 0.05, P < 0.01).

CONCLUSIONShensu II Recipe could postpone the development of GS in FSGS rats possibly through inhibiting the expressions of TGF-beta1 and PAI-1, hindering the over-accumulation of mesangial matrix.
