Objective: To observe the clinical efficacy of moxibustion therapy plus Liu's pediatric massage (tuina) for children with recurrent respiratory tract infections due to qi deficiency of spleen and lung. Methods: A total of 60 children who met the inclusion criteria were divided into an observation group and a control group according to the visiting sequence, with 30 cases in each group. Children in the observation group were treated with moxibustion therapy plus Liu's pediatric massage, and those in the control group were treated with Liu's pediatric massage alone. The incidence of respiratory tract infections and traditional Chinese medicine (TCM) symptoms score were observed and recorded in both groups before and after treatment. And the clinical efficacy was compared between the two groups. Results: The total effective rate of the observation group was 93.3％, and that of the control group was 83.3％. The difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptoms score and total times of infections in both groups were all statistically different from those before treatment (all P<0.05). The differences in TCM symptoms score and infection frequency before and after treatment in the observation group were statistically different from those in the control group (both P<0.05). Conclusion: Moxibustion therapy plus Liu's pediatric massage has a better effect in improving the clinical symptoms and reducing the frequency of respiratory tract infections for children with recurrent respiratory tract infections due to qi deficiency of spleen and lung than the pediatric massage alone.

Objective To investigate the mechanism of hearing loss after focal cerebral ischemia-reperfusion injury in rats.Methods A total of 60 healthy male adult SD rats were included in this study and randomly divided into 2 groups, ischemia-reperfusion(I/R) group and sham operated control, with 30 rats in each group.The rats in I/R group were operated for suture-occluded method to establish middle cerebral artery occlusion(MCAO)model, with ischemia for 60 mins followed by reperfusion for 24 hrs.The control group was only to be isolated cervical vessels, with no thread embolism inserted.The auditory brainstem response (ABR) was tested before operation and at 24 hrs post-operation respectively.At 24 hrs post-operation, we scored neurological functions, measured the changes of water content in the brain using the dry-wet weight method, and determined the infarct volume through TTC method.We also evaluated the integrity of blood-brain barrier(BBB) by viewing the exudation of Evans blue and observed the apoptosis of neurocyte by TUNEL method to conclude apoptotic index(AI).The expression of MMP-9,Claudin-5,Occludin and CX-43 were detected by Western blot.Results Compared with the sham group,the neurological function scores,the infarct volume and water content of the brain increased, with the elevated thresholds of ABR significantly and AI went up in I/R group.The expression levels of MMP-9 and CX-43 were significantly up-regulated,but the expressions of Claudin-5 and Occludin were obviously down-regulated.All of the differences above had statistical significances.Conclusion The mechanism of hearing loss after focal cerebral ischemia-reperfusion injury in rats is possibly related to MMPs activation,neurocyte apoptosis,BBB breakage and gap junction damage.

Background and purpose: The incidence of breast cancer increases as patients age, elderly patients account for a large proportion. Due to the insufifcient systemic therapy, more complications and poorly physical condition, the prognosis of elderly patients is often worse than the younger. The aim of this study was to investigate the safety and tolerance with non-anthracyclin regimen as adjuvant chemotherapy in elderly breast cancer patients. Methods:From Nov. 2008 to Jan. 2012, 56 patients (≥65 years) after surgical excision were enrolled into this study. The patients were divided into two groups:TC and PC groups. Each patient received 4 or 6 cycles of chemotherapy of PC (175 and 600 mg/m2, respectively;n=21) or TC (75 and 600 mg/m2, respectively;n=35), administered intravenously every 3 weeks, as adjuvant chemotherapy. Radiation therapy (as indicated) and endocrine therapy, for patients with hormone receptor-positive disease, were administered after completion of chemotherapy. Results: In this study, 50 patients completed chemotherapy as plan, the proportion of two groups were above 90%. After a median follow-up of 33 months, the median disease-free survival(DFS) and overall survival(OS) were not reached. The relapse-free rate and survival rate were 89.5%and 100%in the PC regime group, which were 90.3%and 96.8%in the TC regime group. Major toxicities included:neutropenia, leucopenia, alopecia, nausea, vomiting and various degree of peripheral neuropathy. The incidence of gradeⅢ-Ⅳneutropenia was 76.2%in PC group vs 48.6%in TC group (P=0.044). The most common cause for withdrawing from treatment was to be unable to tolerate the adverse effects. Conclusion:Adjuvant chemotherapy with paclitaxel and cyclophosphamide is safe, tolerable and promising for elderly breast cancer patients.

OBJECTIVETo learn about the pathogen spectrum and genetic characterization of HFMD with encephalitis in Yantai city.

METHODSStool samples and cerebrospinal fluids (CSF) collected from HFMD with encephalitis cases in Yantai. Virus were isolated from stool samples and identified by fluorescence reverse transcription-polymerase chain reaction. The VPl region was amplified and sequenced from positive specimens. Genetic characterization was identified by sequence analysis.

RESULTSGetting 3 virus strains from 10 stool specimens and all of them belong to EV71. The nucleotide and amino acid homogeneity with the representative isolates of C4a were 98%-99% and 98.90%-99.45% respectively.

CONCLUSIONThe pathogen of HFMD with encephalitis in Yantai city were mainly EV71 wich belong to subgenogroup C4 cluster C4a.

Objective To understand the status and influential factors of those neglect of left-behind children in rural area,and to provide bases for the development of intervention measures.Methods 2917 students were selected as the study subjects from Changfeng county of Anhui province with cluster sampling method and were evaluated by a Parents-Child Conflict Tactics Scales and questionnaire on influential factors.Results 1694 left-behind children,accounted for 58.1％ of the total students,were surveyed in this investigation.The prevalence rates of neglect,among total children,left-behind children,non-left-behind children were 67.4％,70.2％,63.5％,respectively.The prevalence of neglect among left-behind children was higher than that among non-left-behind children (x2=14.322,P＜0.000).There were no significant associations with the neglect rate of left-behind children regarding gender or age differences.Result from multivariate logistic regression analysis indicated that the neglect among the left-behind children were associated with family dysfunction(OR values of moderate and serious family dysfunctions compared to good family function were 1.628 and 2.341,respectively)and the rate of keeping in touch with parents(OR values of sometimes and seldom keeping in touch compared to regular in touch were 1.299 and 1.844,respectively).The starting age of being left-behind(OR values of starting age that being left-behind from 6 to 10 and ≤5 years relative to starting age of left-behind ≥11 years were 0.703 and 0.630,respectively)appeared to be the protection factor to the neglect of those left-behind children.Conclusion Our findings indicated that the status of neglect among the left-behind children was serious.Prevention programs on the issue should target on a number of factors,including the characteristics of the chldren them-selves,as well as on the family of the children.

OBJECTIVETo explore the expression of GSK-3beta, CDK-5 and PP2A and the regulation of them by Abeta(25-35) and ginsenoside Rb1 after neural stem cells (NSCs) are transformed into neurons.

METHODSTo culture NSCs from the dentate gyrus of newborn rats(24 h) hippocampus in vitro. NSCs of the third passage were induced towards neurons; the expressions of GSK-3beta(pTyr279,216), PP2A and the regulation of them by Abeta(25-35) and ginsenoside Rb1 were tested by the immunofluorescence cytochemical staining after NSCs had been induced for one week; The expressions of GSK-3beta, CDK-5, PP2A and the regulation of them by Abeta(25-35) and ginsenoside Rb1 were detected with RT-PCR.

RESULTSImmunofluorescence cytochemisty showed that neural cells from NSCs which had been differentiated after one week could express GSK-3j (pTyr279,216)and PP2A. Abeta(25-35) could enhance the expression of GSK-3beta(pTyr279,216), meanwhile it also restrained the expression of PP2A. Moreover ginsenoside Rb1 could reverse the affect of Abeta(25-35). RT-PCR found that neural stem cells which had been differentiated after one week could express GSK-3beta, CDK-5, PP2A . The expression of GSK-3beta and CDK-5 rose up and the expression of PP2A weakened when they were treated by Abeta(25-35). However, the effect of Abeta(25-35) was restrained when they were pretreated by ginsenoside Rb1.

CONCLUSIONThese observations indicated that NSCs which were cultured and induced in vitro can express GSK-3beta, CDK-5 and PP2A; moreover Abeta(25-35) and ginsenoside Rb1 can regulate the expressions of GSK-3beta, CDK-5 and PP2A. It hints that cells which differentiated from neural stem cells in vitro have protein phosphorylation regulation system of normal cells.
