In order to summarize and perfect the basic skill practicing method in acupuncture teaching and form a characteristic teaching, the research on skill training and technique improving of acupuncture and tuina major was carried out. The undergraduate students in acupuncture and tuina major from College of Acupuncture-Moxibustion and Tuina were randomly divided into an experimental group and a control group. Students from both groups received the basic courses of acupuncture-moxibustion and tuina as requested in the syllabus and the special teaching was added to the experimental group, namely "three practice" (strength practice, coordination practice, targeted practice of acupuncture basic skills) and "three enlightenment" (technique enlightenment, mind and qi enlightenment, efficacy enlightenment). During and after the courses, the teaching effectiveness was evaluated on the basis of needling manipulation. The peacetime score in the experimental group was superior to that in the control group (38.03 +/- 1.14 vs 33.25 +/- 1.31, P < 0.05), the total score in the experimental group was superior to that in the control group (84.03 +/- 6.30 vs 78.05 +/- 6.55, P < 0.05). The special teaching method of "three practice" and "three enlightenment" can improve the effect of skill training teaching method. It highlights the unique feature of central plains by integrating the essence of Shaolin internal qigong and Chen-style Taiji, it can also provide new ideas for the practical teaching of TCM professional courses and the construction of characteristic professionals.

Auto liver transplantation (ALT) has been tremendously popular in hepatic surgery for the liver masses due to lack of enough donor for allogeneic transplantation of liver.But ALT remains stagnant because it is technically more difficult than liver transplantation.Much difficulties in this field lying ahead.Related surgical technical requirements for surgeons operating ALT,complications,difficult liver resection,hypothermic liver perfusion,veno-venous bypass,ex vivo ECMO perfusion and liver trim,assess the quality and volume of autoplast,autoplast implant and vascular anastomosis.On the other hand,the therapeutic effect largely depends on the intraoperative vascular separating range,the location and size of the tumor,the scope of lymphoid infiltrates by neoplast,the intubation site for perfusion and the sequence of opening the occlusion vessel.Thus,it's necessary to set up a scientific,normative ALT procedure to improve the therapeutic effect and prognosis.

Objective To establish a specific fluorescence quantitative method for determining the mRNA expression of Toll-like receptor3(TLR3)in peripheral blood mononuclear cells(PBMCs).Methods Using the Beacon Designer 2.1 software,specific primers and Taqman-MGB probe were designed.The plasmid pMD18-T-TLR3 was constructed as calibrator and the amplified fragment was obtained by reverse- transcript-PCR(RT-PCR).RNA quantification based on cycle threshold values(Ct)was used to establish the standard curve.According to which,the TLR3 mRNA levels in 30 normal individuals,20 patients with primary biliary cirrhosis(PBC)and 20 ones with chronic liver cirrhosis induced by HBV were calculated automatically by software after the fluorescence of PCR product was detected continuously during amplification.Results The linear detection range of the assay for TLR3 gene and ?-actin was 10~2-10~8(r= -0.9974)and 10~3～10~8(r=-0.9984),respectively.The coefficient of variation of both intra-and inter- assay reproducibility for high concentration sample were 6.7% and 8.7%,respectively,and those for low concentration sample were 12.3% and 14.0%.The TLR3 mRNA expression level ranges from 3.46?10~2- 4.51?10~3 copies/?g RNA,4.92?10~2-1.42?10~4 copies/?g RNA and 2.58?10~2-7.17?10~3 copies/?g RNA for 30 healthy individuals,20 PBC patients and 20 ones with chronic liver cirrhosis induced by HBV, respectively.Conclusion We have successfully set up a FQ-RT-PCR method for detecting TLR3 mRNA, which may be used as an excellent tool for the clinic and basic study on the expression of TLR3 gene.

OBJECTIVE To investigate the neuroprotective effect and possible mechanisms of lute-olin-7-O-β-D-glucuronide (LGU) against focalcerebral ischemic injury. METHODS The focal cerebral ischemic injury model was established by middle cerebral artery occlusion (MCAO). Male Sprague Dawley rats were randomly divided into sham group,model group(MCAO),LGU group(0.24,0.72 and 2.16 mg·kg-1)and positive control group(Edaravone at 5 mg·kg-1).LGU was injected intravenously 30 min after MCAO.Neurological severity score,infarct volume and brain water content were detected 24 h after MCAO and the levels of Na+-K+ATPase,Ca2+ATPase,TNF-α and IL-1β were detected to explore the possible mechanisms.For the therapeutic time window test,LGU(0.72 mg·kg-1)was injected intrave-nously 0.5, 2, 4, 6, 8, 10 and 12 h respectively after MCAO. To evaluate motion behavior, LGU were injected intravenously 30 min after MCAO and once per day during detection period. The changes of motor coordination were detected by rotating rod method and grip strength analysis, and the changes of gaits were detected using DigiGait Imaging System. RESULTS LGU improved the neurological severity score, infarct volume ratio and brain water content. The therapeutic time window of LGU for cerebral infarction and brain edema was at least 6 h and for neurological dysfunction was 12 h.LGU also prolonged the latency on rotarod, increased the forelimb tension and improved 8 gait parameters, including stance duration,stride length,stance width,paw area,paw area variability,gait symmetry,ataxia coefficient and tau propulsion.Furthermore,LGU increased Na+-K+-ATPase and Ca2+-ATPase levels in the cortex and hippocampus in the ischemic side,reduced the levels of TNF-α and IL-1β in the serum. CONCLUSION LGU has a significant neuroprotective effect against cerebral ischemic injury via improving energy metabolism and reducing inflammation.

To investigate the changes in bcl-2, bax expression and neuron apoptosis in the hippocampus after the blockade of cervical lymphatics, the model of lymphostatic encephalopathy was established by occluding and removing both the superficial and deep cervical lymph nodes in rats. The animals were sacrificed at 1, 2, 3, 5, 7 and 14 d after operation. H and E staining was used to observe the structure of brain tissues and TUNEL staining was used to detect in situ cell apoptosis in the hippocampus. The expression of bcl-2 and bax in the hippocampus were examined by RT-PCR. The results showed that cerebroedema appeared at day 2 and was most serious at day 5 after the blockade of cervical lymphatics. The number of TUNEL positive cells began to increase at day 2 and reached the maximum at day 5. The expression of bax began to increase at day 1 and reached the maximum at day 2. The expression of bcl-2 began to decrease at day 1 and dropped to the minimum at day 5. The items mentioned above recovered to control level at day 14. These results suggest that lymphostatic encephalopathy following the blockade of cervical lymphatics result in changes in bcl-2 and bax expression in the hippocampus and that apoptosis is the main form of neuron death.

Comparative analysis of variable region ORF14/15 genes of white spot syndrome virus (WSSV) genome in Guangxi Penaeus vannamei (P. vannamei) could provide useful information for the evaluation of genetic diversity and genetic evolutionary relationship among WSSV isolates from Guangxi, China and other places. Based on geographical and temporal considerations, 40 WSSV-positive P. vannamei samples were collected during the period between May 2010 and July 2013 from Beihai, Qinzhou, and Fangchenggang, which were the main P. vannamei production areas in Guangxi, and the variable region ORF14/15 genes of the WSSV genome from all infected samples were amplified by PCR and then subjected to cloning and sequence analysis. Pairwise and multiple alignment analysis was then conducted to evaluate the degree of genetic divergence between different strains. The variable region ORF14/15 genes from 25 of 40 WSSV positive samples were successfully cloned and sequenced; among the ORF14/15 genes of 25 WSSV-positive strains, 22 was 619 bp in length and 3 was 620 bp. All the 25 Guangxi strains carried a 5949-bp deletion in the ORF14/15 region relative to TH-96-II, which has the longest nucleotide sequence in this region; the deletion of Guangxi strains occurred in the middle region of ORF14/15 gene, with only 190 bp and 429 bp/ 430 bp at 5' and 3' ends, respectively, which were coincident with WSSV-IN-05-I in deletion length and position. Sixteen of 25 Guangxi strains had completely identical nucleotide sequences in the variable re gion, and the homology between other strains also exceeded 97.9%. There were single nucleotide substi tution, deletion, and insertion in the ORF14/15 region of Guangxi strains compared with other strains in GenBank. In the phylogenetic tree based on WSSV variable region ORF14/15, the Guangxi strains were closely related and formed a separate branch with Indian strain IN-05-I, but far from other strains in GenBank. The ORF14/15 gene of WSSV isolates in cultured P. vannamei in Guangxi has a large deletion in the middle of the variable region, and the Guangxi WSSV strains show no significant spatio-temporal differences; the Guangxi strains are closer in genetics to Indian strain IN-05-I than other strains in GenBank.

OBJECTIVETo construct the recombinant adenovirus encoding antisense c-myc fragment and to investigate its effect on the chemotherapy sensitivity of osteosarcoma MG-63 cells to cisplatin.

METHODSThe recombinant adenovirus (Ad-Asc-myc) encoding antisense c-myc fragment was constructed by cloning c-myc cDNA of about 720 base pairs in a reverse direction into adenovirus vector, then undergoing recombination, amplifying and being complemented in vivo. The osteosarcoma MG-63 cells were transfected by the Ad-Asc-myc in vitro, and Wright staining, Acridine Orange staining, Western Blot, MTT, Flow Cytometry (FCM) were used to study cell morphology, expression of c-myc protein, tumor cell proliferation in vitro, apoptosis and cell cycle change.

RESULTSAd-Asc-myc encoding antisense c-myc fragment was obtained with the titer of 2 x 10(9) pfu/ml. Ad-Asc-myc down-regulated the expression of c-myc protein after transfected MG-63 cells for 48 h, combined with the treatment of 2.0, 5.0 microg/ml cisplatin for 2 h could inhibit tumor cells proliferation in vitro by 33.4% and 54.2% respectively, which were significantly difference compared with control recombinant adenovirus (Ad-LacZ) groups (P < 0.05). Acridine Orange staining and FCM analysis showed that Ad-Asc-myc could induce apoptosis of transfected cells, which was enhanced by the treatment of cisplatin cell. Cycle analysis showed that obvious G2/M phase arrested in transfected cells.

CONCLUSIONAd-Asc-myc increases the chemotherapy sensitivity of osteosarcoma MG-63 cells to cisplatin as well as induced apoptosis.

OBJECTIVETo explore the efficacy of urethral dilatation with the renal sheath dilator under the ureteroscope in the treatment of male patients with urethrostenosis.

METHODSEighteen male patients with urethrostenosis underwent urethral dilatation with the renal sheath dilator. Under the ureteroscope, a zebra-guide wire was inserted through the stenosed urethra into the bladder and the stenosis was gradually dilated with the renal sheath dilator, followed by placing a Foley catheter of proper size for 1-4 weeks. For children, the renal sheath dilator was selected according to their age, while for adults, metal dilators (> or = F20) were used following dilatation with the F18 renal sheath dilator. All the patients were followed up for 6-24 months.

RESULTSThe operation was successfully performed in all the 18 cases, with no urethral false passage, urethral perforation or urethra tearing. Sixteen of the patients were cured, and the other 2 received urethroplasty for stenosis recurrence. The maximum flow rate was increased to 13.6-30.2 (18.1 +/- 3.5) mL/s after the operation.

CONCLUSIONUrethral dilatation with the renal sheath dilator under the ureteroscope is a simple, safe and effective method for the treatment of urethrostenosis.
