Objective: To observe the clinical efficacy of tuina manipulations in treating different types of tic disorders (TD). Methods: Eligible TD patients were classified into three types, transient tic disorders (TTD), chronic multiple tic disorders (CMTD) and Tourette syndrome (TS), according to their disease duration and severity. The three types of children were treated with the same tuina manipulations. Changes in the Yale global tic severity scale (YGTSS) score, effective rate for tic, and cervical spine imaging examination results (including asymmetry of the lateral atlanto-dental interval, broadened anterior atlanto-dental interval, C2 spinous process deviation, occipito-atlanto-axial flexion/ extension instability) were observed after 1-month and 3-month treatments respectively. Results: The YGTSS score changed significantly after 1-month and 3-month treatments compared with that before treatment (both P<0.01); the effective rate for TD was 46.6％ and 86.7％ respectively after 1-month and 3-month treatments; there were significant differences comparing the effective rate for tic between different types of TD after 1-month and 3-month treatments (all P<0.05); comparing the effective rate for tic after 1-month treatment with that after 3-month treatment for the same type, the intra-group differences were statistically significant [TTD group (P<0.01), CMTD group (P<0.01), TS group (P<0.05)]; the abnormal parameter rates in neck imaging examination after 3-month treatment were significantly different from those before treatment (all P<0.01). Conclusion: Tuina manipulation is effective for TTD, CMTD and TS. It can correct the abnormal alterations of patients' cervical vertebrae, and its efficacy for TTD is most significant.

Objective To assess the effect of continuous early enteral nutrition(EEN)combined with intestinal mucosal protective agents on gut barrier function in patients with severe acute pancreatitis.Methods A total of 79 patients with severe acute pancreatitis selected from four centers between May 2004 to June 2006 were enrolled and divided into EEN combined with intestinal mucosal protective agents group(combined group,n=39)and total parenteral nutrition(TPN)group(n=40).The patients were received either EEN or TPN when homeostasis were achieved within 72 hours after onset.The patients in combined group were administered pepti-2000 variant combined with glutamine,arginine and intestinal mucosal protective agents.The patients in TPN group were administered through a central vein.APACHE-Ⅱ score was recorded every week;The concentration of serum amylase,plasmic diamine oxi dase(DAO)and endotoxin were mesured on day 1,7,14 and 21 as well as urinary excretion of lactulose (L)and mannitol(M).Complications,lenth and charges of hospital stay were recorded.Results There was no death in both groups.The APACHE-Ⅱ score decreased on day 7,but lower in combined group (6.00±1.60)than that in TPN group(7.08±2.34)(P＜0.05).On day 7,14 and 21,the concentrations of endotoxin in combined group was(39.30±15.82),(22.64±14.31),(14.81±10.93)Eu/L,respectively,urinary L/M ratio was 0.28±0.25,0.21±0.18 and 0.08±0.04,respectively,IFABP-c was 15.62±5.26),(5.46±1.18)and(3.26±0.94)pg/ml,respectively.All of these parameters were significantly lower than those in TPN group(P＜0.05).The infectious rates including pancreatic,peritoneal and respiratory infection in TPN group were much higher than that in combined group(26.47% vs 3.44%,P＜0.01).The composition of flora fecal remained unchange in combined group rather than TPN group.The mean hospital stay was shorter in combined group[(20.0±5.7)days]compared to TPN groups[(34.5±12.9)days].The charges were also significantly lower in combined group,with average cost of RMB 25,900±14,200,while it was 46,800±4,030 in TPN group.Conclusions EEN combined with intestinal mucosal protective agents can improve gut barrier function via reducing the gut permeability,improving the hypoperfusion,maintaining the integrity and gut fecal flora.It might reduce the course and charges of hospital stay.

Objective To determine levels of serum Leptin,insulin like growth factor-1(IGF-1),interleukin-6(IL-6) and tumor necrosis factor-alpha(TNF-?) in newborn infants with hypoxic-ischemic encephalopathy(HIE).Methods The asphyxiated and normal term neonates were included.The HIE group contained 45 cases and control group 20 cases.Serum Leptin,IGF-1,IL-6 and TNF-? levels were measured by a sensitive enzyme-linked immunosorbent assay.Results In asphyxiated term neonates,serum Leptin,IGF-1,IL-6 and TNF-? levels were significantly higher or lower than those in control group(all P

To clarify the pathogenesis of Duck enteritis virus (DEV), the cDNA library of duck's liver infected by DEV and a bait plasmid containing DEV nucleocapsid protein (NP) gene were constructed, then the receptor was screened from the cDNA library plasmid by the yeast two-hybrid system and verified by GST pull-down test. The results showed that the capacity of the primary cDNA library was 1 x 106 CFU with insertion size from 0.5 to 1 kb, and the bait plasmid of pGBKT7-NP showed no self-activation. The receptor reacting with DEV NP in duck liver was initially confirmed as the protein kinase C inhibitor (PKCI). These results provide new clues for further investigation on pathogenesis of DEV.

AIMTo further explore the roles of endogenous nitric oxide (NO) or NO derivatives in complex partial seizures and generalized convulsions.

METHODSThe effect of pretreatment with L-nitroarginine (L-NNA), an inhibitor of nitric oxide synthase (NOS), or L arginine (L-Arg), a precursor of NO on kainic acid (KA)-induced seizure in rats and the changes in the concentration of NO2 -/NO- in the hippocampus were determined.

RESULTSThe rats appeared with wet dog shakes (WDS) at 15 min and then occurred generalized convulsions during 1 h to 3 h after administration of KA (10 mg/kg i.p.). However, the pretreatment of L-NNA (50 mg/kg) so dramatically promoted and enhanced KA-induced behavioral seizures that the latency of generalized convulsion was shorten dramatically, and the mortality was greatly high. In contrast, the pretreatment with L-Arg (40 mg/kg) markedly delayed or weakened KA-induced behavioral changes, such as increasing latency of WDS and generalized convulsion, shortening time o f seizure and none of animal died during observed time. The concentration of NO2- /NO3- in the hippocampus increased immediately at 30 min and remained to 7 d after the administration of KA. Compared with control group (pretreatment with NS), the concentration of NO2- / NO3- in the hippocampus apparently increased at 3 h and 3 d after the administration of KA in the rats with L-Arg pretreatment.

CONCLUSIONThe endogenous NO (NO or NO derivatives) mediators may play an important role against excitotoxin induced seizures in rats.

OBJECTIVETo study the effects of virtual reality (VR) training on the gross motor function of the lower limb and the fine motor function of the upper limb in children with spastic diplegia cerebral palsy.

METHODSThirty-five children with spastic diplegia cerebral palsy were randomly assigned to VR training group (n=19) and conventional training group (n=16). The conventional training group received conventional physical therapy and occupational therapy for three months. The VR training group received VR training and occupational therapy for three months. Grip and visual-motor integration subtests in Peabody Developmental Motor Scales-2 were used to evaluate the fine movement in patients before and after treatment. The D and E domains of the 88-item version of the Gross Motor Function Measure (GMFM-88), Modified Ashworth Scale (MAS), and Berg Balance Scale (BBS) were used to evaluate the gross movement in patients before and after treatment.

RESULTSBefore treatment, there were no significant differences in grip, visual-motor integration, fine motor development quotient, scores of D and E domains of GMFM-88, MAS score, or BBS score between the two groups (P>0.05). After treatment, all the indices were significantly improved in the VR training group compared with the conventional training group (P<0.05).

CONCLUSIONSVR training can effectively improve the gross motor function of the lower limb and the fine motor function of the upper limb in children with spastic diplegia cerebral palsy.

OBJECTIVETo generate a gene delivery plasmid carrying the dominant negative form of the protein phosphatase 2A catalytic subunit a (DN-PP2Aca) driven by a hepatocellular carcinoma (HCC) tissue-specific promoter and investigate its ability to inhibit growth of cultured hepatoma cells.

METHODSThe gene delivery plasmid was constructed by PCR-amplifying DN-PP2Aca from wild-type PP2Aca using site-directed mutagenesis and then ligating the sequence-verified amplicon downstream of an alpha-fetoprotein enhancer and phosphoglycerate kinase promoter (AFpg) in the luciferase reporter vector pGL3-Basic. Following transfection into two AFP+ hepatoma cell lines (HepG2 and HepG3) and two AFP- hepatoma cell lines (SK-HEP-1 and L02), the transcriptional activity of the AFpg-driven DN-PP2Aca plasmid was tested using luciferase reporter gene assay and western blotting. The effect on cell growth was tested using MTT assay. Between group differences were assessed by t-test.

RESULTSThe AFpg-driven DN-PP2Aca plasmid showed high transcriptional activity and protein expression in both HepG2 and Hep3B cells. At 72 h after transfection, the proliferation capacities were repressed by 42.65%+/-3.99% (P = 0.0002) and 39.87%+/-3.91% (P = 0.0002) in AFP+ HepG2 and Hep3B cells, respectively (vs. untransfected). In contrast, the plasmid was transcriptionally inactive in and had no effect on proliferation of AFP- cells.

CONCLUSIONThe AFpg-driven DN-PP2Aca plasmid exhibits selective cytotoxicity against AFP+ hepatoma cells, and may represent a useful gene therapy strategy to treat HCC.

OBJECTIVETo examine the recent incidences and trends of childhood malignant solid tumors in Shanghai.

METHODData from the population-based Shanghai Cancer Registry and related retrospective survey were used to analyze the patterns of incidence and trends of malignant solid tumors diagnosed between 2002 and 2010 in children aged 0-14 years. The distributions of incidences were described according to gender, age and cancer types which were classified according to International Classification of Childhood Cancer (ICCC). Annual age-standardized rates (ASRs) were adjusted by the world standard population. Approximate confidence intervals for standardized rate ratios (SRR) based Poisson distribution test-based methods were used to assess changes in incidence over the period 2002 - 2006 and 2007 - 2010.

RESULT(1)A total of 868 cases of childhood malignant solid tumors were diagnosed in Shanghai during 2002 - 2010, accounting for 65.8% of all childhood cancers. The ASR of 2002 - 2010 was 80.2 per million for all solid tumors. (2) The ASR was higher in boys (86.3 per million) than in girls (73.8 per million) with SRR 1.2 (95%CI 1.0 - 1.3). Incidence rate was the highest in the first five years of life with 93.4 per million. The age-specific incidence rates in 5 - 9 and 10 - 14 age groups were 65.2 and 79.3 per million, respectively. (3) CNS tumors, lymphomas, germ cell tumors, neuroblastoma, and soft tissue sarcomas were the top 5 most common solid tumors in children, with the incidence rate of 23.8, 11.0, 7.8, 7.7 and 6.8 per million, respectively. The patterns of subgroups varied in different age groups. Blastomas, such as neuroblastoma, retinoblastoma, were more common in the children aged 0 - 4 years, whereas epithelial carcinomas and bone tumors developed more frequently in elder children aged 10 - 14 years. (4) Compared with the ASR in 2002 - 2006, the ASR for both genders in 2007 - 2010 had no substantial changes (78.7 per million in 2002 - 2006 and 82.9 per million in 2007 - 2010). However, among boys, the incidence rate in 2007 - 2010 was significantly higher than that in 2002 - 2006 with SRR 1.2 (95%CI: 1.0 - 1.4). For specific subgroups of cancer, there were no substantial changes. Some cautions should be taken when interpreting results involving a small number of cases per year and those with wide 95% confidence intervals.

CONCLUSIONThe incidence rate of pediatric malignant solid tumors among males was higher than females during 2002 - 2010, and it differed among different age groups with the highest in the first five years of life. CNS tumor was the most common type of solid tumors in children. This was a unique characteristics comparing with adult reflected in disease spectrum and age of onset. The patterns of incidence and its trends for childhood malignant solid tumors in Shanghai could provide a basis for etiologic research and preventive interventions. The findings also suggest an urgent need for longer population-based surveillance to verify the pattern and changing trends.
