OBJECTIVETo investigate the nephrotoxocity of Longdan Xiegan Tang in rats, and to test its safety.

METHODSprague-Dauley rats were given Longdan Xiegan Tang 4.5 mL x (100 mg)(-1) Bid for thirty days, and the control group was given NS. MTP, BUN, Cr, MDA, MTP/Ucr and SOD were measured on 1st, 2nd, 3rd, 4th week. The kidney tissues were viewed with light microscopy and electron microscope.

RESULTMTP and MTP/Ucr were obviously higher than controls ( P < 0.01), and the other index had no difference (P > 0.05). No remarkable structural change could been seen with light microscopy, but with electron microscope we could find that the basal membranes were thickened and some of foot process were infused.

CONCLUSIONLongdan Xiegan Tang will result in injury of kidney function.

OBJECTIVETo investigate the effect of huanglian jiedu tang on Alzheimer' s disease, and its influence on cytokines.

METHODAD rats models were made by A beta injection, and then water-maze tests were made to investigate the study and memory ability. TNF-alpha, INF-gamma and IL-2 were examined by ELISA. After treatment with huanglian jiedu tang, the rats were evaluated again.

RESULTAfter A beta injection, the study and memory ability of the rats was decreased. By the treatment with huanglian jiedu tang, it was improved (P < 0.01); TNF-alpha, INF-gamma and IL-2 levels of AD rats were higher than those in control group (P < 0.01); after treatment the levels came down (P < 0.01).

CONCLUSIONHuanglian jiedu tang can improve the study and memory ability of AD rats by changing their immune state.

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.

OBJECTIVETo investigate pave a way for studying pathogenicty of HBoV.

METHODSIsolation and cell culture of HBoV by human bronchial epithelial cell line, which was founded in our laboratory. The morphology of the virus were primarily studied with a transmission electron microscope. In addition, transcript mRNA was detected in human bronchial epithelial cells, which was passaged and infected within HBoV, using the reverse-transcription polymerase chain reaction (RT-PCR). The amplified products nucleotide sequence of HBoV were sequencing and sequence analysis.

RESULTSCytopathic effect (CPE) was observed after the aseptic residue of filtration of 2 case sputum specimens with HBoV, which was inoculated to the human bronchial epithelial cell line. The virus particles were observed in the cytoplasm, which were hexagonal or spherical in shape and 18-26 nm in diameter,bulk was 20 nm. cDNA amplicon obtained 295 bp fragment results of electrophoresis bands as same as NS1 region of the conserved matrix gene of publish sequence of HboV. PCR products nucleotide sequence of HboV were compared with corresponding HboV GeneBank sequences. The comparison/alignment and construction of phylogenetic trees also point to an affiliation of the parvovirus to the species HBoV.

CONCLUSIONIsolation and identification of HBoV could be done in the human bronchial epithelial cell, and we found some characterizing CPE in the human bronchial epithelial cell after HBoV infection. The above studies pave a way for studying pathogenicty of human bocavirus.

OBJECTIVETo clone and express VP, gene from HBoV, and the expressed VP, protein was as the antigen in order to detect serum from children in Wenling area with lower respiratory tract infections.

METHODSThe VP, gene was recombined with the genome of Baculovirus, which infected the insect cell. The fusion protein with HA tag was applied to confirm the specificity of expressed protein. Furthermore, the recombinant protein was observed using electron microscopy. The 176 serum from children in Wenling area with lower respiratory tract infections was screened using Western blot.

RESULTSThe expressed VP2 protein was more than 60% in total proteins from insect cell, and MWt about 60 x 10(3). The virus-like particle (VLP) was observed using electron microscopy, and size about 20 nm. The 176 serum from children in wenling area with lower respiratory tract infections was screened using Western blot. The HBoV positive rate was 2.28% (4/176).

CONCLUSIONThe VP2 protein from human bocavirus was expressed in insect cell successfully. Through HA tag the VP2 protein was specific, and then the assay using SDS-PAGE with Western blot could detect and screen the antibody in serum from children with lower respiratory tract infections rapidly and accurately.
