Objective To investigate the expression of thymosin beta4 ( Tβ4 ) in the liver tissues of children with hepatoblastoma ( HB) , and further study the function of Tβ4 in HB metastasis in vitro. Methods Immunohisto-chemistry (IHC) was used to determine expression of Tβ4, E-cadherin andβ-catenin in liver tissues from 19 chil-dren with HB,and further to analyze its function in metastasis of HB cells. Results The positive rate of Tβ4 ( P<0.01 ) in HB liver tissues was significantly higher than it in the adjacent tissues. The positive rates of Tβ4 and nu-clearβ-catenin in HB with lymphnode metastasis were significantly higher than in HB without lymphnode metastasis ( P <0.01 ) . While expression of E-cadherin in HB with lymphnode metastasis was lower than in HB without lymphnode metastasis ( P<0.01 ) . Scratch-wound assay showed that HepG2 cells with Tβ4 knockdown had signifi-cantly lower metastatic ability (P<0.05). Conclusion Tβ4 plays an important role in HB metastasis, suggesting it is a potential target for HB metastasis.

Objective To study the characteristics of lower respiratory tract infection by Streptococcus pneumonia in children aged from 0 to 5 years and drug resistance,so as to provide the rational basis for clinical treatment and epidemiology.Methods The medical data from 4 815 children aged 0 to 5 years with lower respiratory tract infection between September 2014 and September 2016 were retrospectively reviewed.Results Totally 343 strains of Streptococcus pneumonia were isolated from 4 815 sputum samples,with the isolation rate of 7.12％.Of the isolated streptococcus pneumonia strains,80.76％ were isolated from the children with pneumonia,9.33％ were isolated from the children with bronchitis,5.83％ were isolated from the children with capillary bronchitis,4.08％ were isolated from the children with bronchial asthma.There was no significant difference in the incidence of Streptococcus pneumonia infections between the genders of the children(P>0.05),but the incidence of Streptococcus pneumonia detection rates differed significantly in different seasons and children of different ages,the difference was statistically significant(P<0.05).The resistance rates of Streptococcus pneumonia to penicillin,erythromycin and clindamycin were 51.0％,97.9％ and 97.1％ respectively;The sensitivity rates to cefotaxime and vancomycin were 71.1％ and 100.0％ respectively.Conclusion The children aged less than 1 years old are at the high risk of Streptococcus pneumonia infection and highest detection rates in winter,it is necessary to perform the drug susceptibility testing in a timely manner so as to choice reasonable antimicrobial agents to control the condition.

Objective: To explore the burden of spouse caregivers of patients with dementia at home and factors having influence.Methods:Forty-two patients with dementia were collected from psychiatric out-clinic consecutively. Trained investigators did home visit to collect data on severity of the disease (CDR, MMSE), pathological behavior (BEHAVE-AD), activity of daily living (ADCS-ADL) and burdens of their spouse as caregiver (CBI). The caregivers' anxiety, depression (Zung's Anxiety Scale and Depression Scale) and knowledge about dementia were also collected.Results:The caregivers felt big burden (BDI total score: 30.7?15.1). Nearly half of them (42.9%) were in depression and one quarter (23.8%) were anxious. They were lack of knowledge about dementia and unskillful in care-giving. 26.2% caregivers thought dementia is curable or equal to normal aging, 57.1% of them did not believe it is an improving disease. The burden of caregivers was correlated positively with pathological behavior of patients (r=0.40, P

BACKGROUND:Studies have shown that ankle-foot orthosis can increase the feedback on the input information from receptors in the skin of the foot and leg to improve the ankle joint position sense, and promote brain function reorganization.
OBJECTIVE:To systematical y evaluate the effect of ankle-foot orthosis on the improvement of walking in hemiplegic patients.
METHODS:The Chinese Biomedical Literature Database, CNKI, WanFang Data and VIP database were searched for reports of randomized control ed trials of ankle-foot orthosis to improve walking ability in hemiplegic patients, from the date of establishment of each database to June 2013. The randomized control ed trials which met the criteria were included for the Meta-analysis.
RESULTS AND CONCLUSION:A total of 9 randomized control ed trials involving 456 patients were included. Meta-analysis showed that, compared with conventional treatment and drug therapy, ankle foot orthosis via the continuous treatment shows certain advantages to improve lower extremity motor function in hemiplegic patients, life skil s and 10-meter maximum walking speed. Due to a limited number of included documents, the remaining indicators such as walking speed, stride difference and balance function were only for appropriate descriptive analysis. The results suggested that, by improving abnormal gait, walking speed, stride frequency, gait cycle, space asymmetry, ankle muscle spasms and balancing, the ankle-foot orthosis could achieve the goal of improving walking function. Ankle-foot orthoses could not be confirmed to exert the role in the fol owing indicators, including time asymmetry, double support phase prolongation and stride length. This evidence shows that ankle-foot orthoses in hemiplegic patients may promote recovery of motor function of the lower limbs and activities of daily living to a certain extent, but the more high-quality, multi-center randomized control ed trials with large samples are necessary.

AIM:To study the differences of basic fibroblast growth factor(bFGF)gene expression in lens epithelial cells (LECs) between fetuses and cataract patients. METHODS: In situ hybridization was used to detect bFGF mRNA in the LECs that were cultured and in tissue sections from fetuses and in the LECs from the anterior capsule of cataract patients. Image analysis was used for the relative quantitative analysis of bFGF mRNA. RESULTS: bFGF gene existed in the LECs that were cultured and in tissue sections from fetuses and in the LECs from the anterior capsule of cataract patients. The integral absorbance for the fetal cultured cells, the fetal tissue sections and the capsule membrane cells of cataract patients were 627.1±268.7, 131.5±42.8 and 79.2±26.3 respectively. The integral absorbance of fetal cultured LECs was significantly higher than that of fetal section LECs (P<0.01). The integral absorbance of cataract LECs was significantly lower than that of fetal LECs (P<0.01). CONCLUSION: The in vitro culture of LECs can improve bFGF gene expression. The bFGF gene expression in fetal LECs is significantly higher than that in cataract LECs.
