Objective To observe the efficacy difference between different needling manipulations in treating acute stroke with point-toward-point needling at scalp acupoints, for seeking the optimal treatment protocol. Method Ninety patients with acute stroke were randomized into a manual needling group, an electroacupuncture group, and a needle-retaining group, 30 cases each. In addition to the neurological treatment, the three groups were all given point-toward-point needling from Baihui (GV20) to Taiyang (EX-HN5) on the affected side, respectively with manual twisting, electroacupuncture and needle retaining methods. Before and after 14-day treatment, the Neurological Deficit Score (NDS), level of neuron specific enolase (NSE) and total efficacy were compared among the three groups. Result The NDS dropped significantly in the three groups after the intervention (P<0.05); the manual needling group showed the most significant improvement, better than the electroacupuncture group and needle retaining group. The level of NSE declined significantly in the three groups after the intervention (P<0.05); the decrease in the manual needling group was the most significant compared to that in the electroacupuncture group and needle retaining group. The total effective rate in the manual needling group (90.0%) was significantly higher than that in the electroacupuncture group and needle retaining group (P<0.05). Conclusion Point-toward-point needling at scalp acupoints with manual operation can effectively improve the neurological deficit in stroke patients, and the application of needling manipulations can further enhance the therapeutic efficacy, which is specific.

OBJECTIVETo investigate the expression of microRNA(miR)-21 and miR-125 in colorectal cancer (CRC) and its relationship with clinicopathological features.

METHODSQuantitative real-time PCR was applied to examine the expression of miR-21 and miR-125 in 100 primary CRC specimens which were diagnosed and operated in West China Hospital between 2006 and 2007, in comparison with the corresponding normal mucosa specimens. The relationship between the expression of miRNAs and clinicopathological features was analyzed.

RESULTSThe expression of miR-21 in CRC was up-regulated by 2.3 times compared to normal mucosa (P =0.025), while the expression of miR-125 was down-regulated by 3.3 times in comparison with normal mucosa (P =0.005). Furthermore, the expression of miR-21 was related to TNM stage (P =0.028) and local invasion (P =0.023). On the other hand, no significant relationship was found between the expression of miR-125 and clinicopathological features (P >0.05).

CONCLUSIONThe over-expression of miR-21 may play a role in the development and progression of CRC, while miR-125 may not be related to the pathogenesis of CRC.

OBJECTIVETo investigate the presence of Cosmc gene mutation in children with Henoch-Schönlein purpura (HSP) and the association between Cosmc gene mutation and the susceptibility to HSP.

MESULTSEighty-four children who were diagnosed with HSP between March 2014 and December 2015 were selected as the HSP group. Fifty-eight healthy volunteers matched for age and sex were enrolled as the control group. Fasting venous blood (5 mL) from the two groups was collected in EDTA anticoagulated tubes, followed by the isolation of peripheral blood mononuclear cells (PBMCs) through density gradient centrifugation. Genomic DNA was extracted from PBMCs according to the manufacturer's protocol, and the whole exon region of Cosmc gene was amplified by touch-down polymerase chain reaction (touch-down PCR). The PCR products were identified by 1% agarose gel and sequenced in order to further examine the association between Cosmc gene mutation and the susceptibility to HSP.

RESULTSSequencing results showed two mutations (c.393T>A and c.72A>G) of Cosmc gene in children with HSP. There were no significant differences in the genotype and allele frequencies at the two loci between the HSP and control groups, and this distribution was not associated with sex.

CONCLUSIONSThe mutations c.393T>A and c.72A>G in the exon region of Cosmc gene in children with HSP are not associated with the onset of HSP.

AIM:To investigate the expression of serine-arginine-rich splicing factor 9/serine-arginine-rich protein 30c (SRSF9/SRp30c) and glucocorticoid receptor β(GRβ) in the glioma cells and the relationship of them. METHODS:Small interfering RNA ( siRNA) was used to knock down the expression of SRSF9 in the U87 cells.Short hairpin RNA ( shRNA) derived from lentivirus was used to establish U 87 stable knockdown cell line .Fluorescence micros-copy was used to observe and detect transfection efficiency .The expression of Grβand SRSF9/SRp30c at mRNA and pro-tein levels was determined by RT-qPCR and Western blot .The cell viability , colony formation ability and migration ability were measured by CCK-8 assay, colony formation assay and wound healing experiment .RESULTS:The mRNA and pro-tein levels of SRSF9/SRp30c and Grβin the U87 cells were both down-regulated after knockdown of SRSF9 (P<0.05). Fluorescence microscopic observation showed that a stable cell line was constructed successfully , and the transfection effi-ciency exceeded 80%.After knockdown of SRSF9 expression in the U87 cells, the cell viability and colony formation abili-ty were reduced (P<0.05).The migration ability was weakened significantly after SRSF9 was knocked down (P<0.05). CONCLUSION:SRSF9/SRp30c may promote the proliferation and migration of the glioma cells by regulating GRβ.

OBJECTIVETo investigate the structural characteristics and clinical significance of two-dimensional tumor microvascular architecture phenotype (2D-TMAP) in non-small cell lung cancer (NSCLC).

METHODSThirty surgical specimens of NSCLC were collected. The sections of the tumor tissues corresponding to the slice of CT perfusion imaging were selected to construct the 2D-TMAP expression. Spearman correlation analysis was used to examine the relation between the 2D-TMAP expression and the clinicopathological features of NSCLC.

RESULTSA heterogeneity was noted in the 2D-TMAP expression of NSCLC. The microvascular density (MVD) in the area surrounding the tumor was higher than that in the central area, but the difference was not statistically significant. The density of the microvessels without intact lumen was significantly greater in the surrounding area than in the central area (P=0.030). The total MVD was not correlated to tumor differentiation (r=0.042, P=0.831). The density of the microvessels without intact lumen in the surrounding area was positively correlated to degree of tumor differentiation and lymph node metastasis (r=0.528 and 0.533, P=0.041 and 0.028, respectively), and also to the expressions of vascular endothelial growth factor (VEGF), ephrinB2, EphB4, and proliferating cell nuclear antigen (PCNA) (r=0.504, 0.549, 0.549, and 0.370; P=0.005, 0.002, 0.002, and 0.048, respectively). The degree of tumor differentiation was positively correlated to PCNA and VEGF expression (r=0.604 and 0.370, P=0.001 and 0.048, respectively), but inversely to the integrity of microvascular basement membrane (r=-0.531, P=0.033).

CONCLUSIONThe 2D-TMAP suggests the overall state of the micro-environment for tumor growth. The 2D-TMAP of NSCLC regulates angiogenesis and tumor cell proliferation through a mesh-like structure, and better understanding of the characteristics and possible mechanism of 2D-TMAP expression can be of great clinical importance.
