OBJECTIVETo explore the mechanism of electroacupuncture therapy on Parkinson's disease (PD).

METHODSFifty Wistar rats were randomly divided into a normal group, a sham-operation group, a model group, a Fengfu-Taichong group and a Shuanggu Yitong group. PD model was duplicated by microinjection of 6-Hydroxyl-Dopamine into right corpora striata, and by microinjection of normal saline in sham-operation group. Rats in normal group, sham-operation group and model group were not treated. In Fengfu-Taichong group, the rats were treated by electroacupuncture at "Fengfu" (GV 16) and "Taichong" (LR 3) on the basis of the PD model, and by electroacupuncture at "Fengfu" (GV 16), "Taichong" (LR 3), "Guanyuan" (CV 4) and "Zusanli" (ST 36) in Shuanggu Yitong group, once daily for 2 weeks. GDNF and Ret expression were detected by immunohistochemistry and western blotting, respectively.

RESULTSThe number of GDNF positive cells and the content of Ret receptor increased significantly in the two electroacupuncture groups compared with those in the other groups (all P < 0.01), and the expression of GDNF increased significantly in Shuanggu Yitong group compared with that in Fengfu-Taichong group (P < 0.01).

CONCLUSIONElectroacupuncture can not only increase the expression of GDNF, but also enhance its effect. "Shuanggu Yitong" method is better than simple acupuncture at "Fengfu" (GV 16) and "Taichong" (LR 3) in increasing expression of GDNF.

Objective Influenza A(H7N9) virus causes a relatively high mortality in humans and therefore it is of great sig-nificance to know its prevalence in China .This article aimed to study the genetic characteristics and evolution of the hemagglutinin (HA) gene of the influenza A(H7N9) virus prevailing in China between 2013 and 2017. Methods We downloaded the HA se-quences of the influenza A ( H7N9) virus prevailing in China between 2013 and 2017 from The Global Initiative on Sharing All Influen-za Data and National Center for Biotechnology Information .Using the bioinformatics software , we analyzed the homology , molecular characteristics , phyletic evolution , and selective pressure of the HA gene. Results The homology of the HA gene of the influenza A ( H7N9) virus and the reference strain was decreasing each year from 2013 to 2017, 99.0%-99.9%in 2013, 98.7%-99.5%in 2014, 98.4%-99.6%in 2015, 76.8%-99.4%in 2016, and 69.9%-98.2%in 2017.Compared with the reference strain , the HA gene of the influ-enza A(H7N9) virus underwent variations in 21 antigenic sites.The variation of N285D was the highest (23%) in 2015 and that of R148K increased yearly,reaching 65%in 2016 and 78.5% in 2017. Phylogenetic analysis showed a concentrative distribution of the influenza A ( H7N9) virus strains on the phylogenetic tree in the same year from 2013 to 2017.Amino acid substitution of T 140A was observed in most of the influenza A ( H7N9) virus strains from Guang-dong in 2013, and the widest distribution of the virus strains was found in 2014.Positive selective pressure site 65 was obtained in the sequence of 2015 using the FEL and IFEL models, but not in the strains of 2016 or 2017. Conclusion Influenza A(H7N9) virus constantly undergoes variation , which has increased the difficulty in its prevention and control .More importance should be attached to observation of the virus and response to its adaptive mutations .

OBJECTIVETo study the expression of anaplastic lymphoma kinase (ALK) and survivin proteins in anaplastic large cell lymphoma (ALCL) and there clinical significance.

METHODSThe morphologic characteristics were studied by routine light microscopy. Immunohistochemical staining for ALK and survivin proteins was performed using LSAB method.

RESULTSALK protein was positive in 51 cases (63%) and negative in 30 cases (37%) of the 81 cases of ALCL studied. The prognosis of patients with ALK protein expression was better than those without ALK expression (P < 0.05). As for survivin protein, there were various degrees of expression in all the 77 ALCL cases studied. High level of survivin protein expression was observed in 33 cases (42.9%), while low level of expression was seen in 44 cases (57.1%). The expression of survivin protein did not correlate with that of ALK protein (P > 0.05). The survival rate was significantly lower in patients with high survivin protein expression (P < 0.05). In cases with ALK protein expression, the prognosis was less favorable if there was also high co-expression of survivin protein (P < 0.05). In ALK protein negative cases, prognosis did not significantly correlate with the expression of survivin protein (P > 0.05). In addition, multivariate analysis confirmed the prognosis value of ALK protein expression, survivin protein expression and constitutional symptoms.

CONCLUSIONSurvivin protein expression can serve as an independent prognostic predictor of unfavorable clinical outcome in patients with ALCL, especially when ALK protein is positive.
