Objective To evaluate the quality of clinical trials about acupuncture and moxibustion treatment of vertebrobasilar insufficiency in China.Methods Literature of clinical trials of acupuncture was collected and analyzed,evaluated by the randomized controlled test criteria and the clinical assessing method in Cochrane handbook of international Cochrane cooperation net.Results Sixteen literatures were brought in.87.5% of the included literature had no clear description of random methods,and no allocation concealment,use of blind methods,sample size calculation,intention-to-treat analysis.Among them,62.5% had explicit diagnosis criteria,12.5% with correct randomizing method,62.5% with explicit evaluation criteria,however,31.22% with no words referring to the comparability among the groups.Conclusions Though acupuncture and moxibustion have been widely applied in prevention and treatment of vertebrobasilar insufficiency,it can not provide evidences of higher reliability for clinical treatment due to less clinical randomized controlled tests and lower quality,which severely hinder testing and verifying of clinical therapeutic effects of acupuncture and moxibustion.It is proposed that multiple central and randomized controlled test should be made,so as to search for feasible acupuncture and moxibustion methods with definite therapeutic effect for vertebrobasilar insufficiency,and provide basis for further systematical evaluation.

Objective To analyze the epidemiological characteristics for new detecting cases of leprosy in 2012, in Yunnan Province, and provide clue and foundation for prevention and treatment in leprosy control. Methods The date of diagnosed leprosy patients in 2012 in Yunnan Province were collected and analyzed by disease reporting information system. Results 230 new cases were founded in 2012, and the discovery rate was 0.50/100 000. 4.35% of new cases were children, 64.35% of new cases were MB and 19.57% had grade 2 disability. 17 recurrent cases were founded in 2012,and 6 of them had received MDT. By the end of 2012, there were still 1084 present case in Yunnan Province,the prevalence rate was 0.24/10 000,and 485 of them need MDT. Conclusion The prevalence of leprosy was decreased,and the prevalence varies a lot in different regions. Honghe and Wenshan are still the focus regions. Leprosy is still a serious public health and social problem in Yunnan Province. In order to reduce the burden of leprosy and eliminate the leprosy danger, long-term financing investment and prevention are still needed.

AIM:To observe the effects of neuroglobin ( NGB) overexpression on the apoptosis induced by Aβin the brains of double transgenic AD ( APPswe/PS1dE9) mice and to explore its potential mechanisms .METHODS:Twenty-four 13-month-old double transgenic AD mice were randomly divided into 3 groups:intracerebroventricular injection with normal saline (NS) group, intracerebroventricular injection with pcDNA3.1 and NS group, and intracerebroventricular injection with pcDNA3.1 and pNGB group.Immunohistochemistry was used to detect the expression of Aβ1-42 in the brains. TUNEL staining was used for analyzing the apoptosis , and the protein levels of cleaved caspase-3, caspase-9, PI3K, Akt and p-Akt were determined by Western blot .RESULTS: After intracerebroventricular injection with pNGB , the areas of Aβ1-42 in the hippocampus and cortex were decreased compared with NS group and pcDNA 3.1+NS group (P<0.01).The TUNEL-positive staining cells in the pNGB group were less than those in NS group and pcDNA 3.1 group ( P<0.01 ) . NGB overexpression attenuated the protein levels of cleaved caspase-3 and caspase-9 (P<0.01), but induced the produc-tion of PI3K and p-Akt (P<0.01).CONCLUSION:Overexpression of pNGB significantly inhibits the generation of Aβand attenuates the apoptosis induced by Aβ, indicating that NGB overexpression activates PI 3K/Akt pathway and inhibits the production of cleaved caspase-3 and caspase-9, which were tightly related with apoptosis .

Objective To investigate the inhibitory effect of recombinant LIGHT-Fe gene on the proliferation of human esophageal carcinoma cell line Eea109. Methods LIGHT-Fc expression vector was transfected into human esophageal squamous carcinoma cell line Eca109 by using DOTAP liposomal transfection reagents. The effects of LIGHT-Fc gene on the proliferation of esophageal carcinoma cell line Eca109 in vitro were detected by cell growth curve and MTr assay. Forty-five nude mice were equally divided into Eea109/Wt group, Eca109/neo group and Eca109/LIGHT group. Carcinogenesis and pathological expression of the esophageal carcinoma tissues were observed. Results The expressions of LIGHT receptors were detected in Eca109 cells. The proliferation of Eca109 cells was inhibited after trasfecting LIGHT-Fc gene into Eca109 cells. The numbers of tumors generated in Eea109/Wt group, Eca109/neo group and Eca109/LIGHT group were 12, 11 and 5, with statistical significance between Eca109/LIGHT group and the other two groups (X2 =6.652, 4.821, P <0.05). The result of histopatholagical examination indicated that the tissue necrosis appeared significantly in tumors derived from Eea109/LIGHT cells. Conclusions The growth of esophageal squamous carcinoma cell line Eca109 can be suppressed by LIGHT-Fc gene whether in vitro or in vivo.

AIM: To study the neuroprotective roles of neuroglobin (NGB) over-expression in the SH-SY5Y cells transfected with pAPPswe.METHODS:The plasmid pEGFP-NGB was successfully constructed and transfected into the SH-SY5Y cells, which were pretreated with pAPPswe.MTT assay was applied to detect the effect of NGB over-expres-sion on the cell survival rates.JC-1 staining was used to detect the level of mitochondrial transmembrane potential.The cell apoptosis was analyzed by flow cytometry.The effects of NGB over-expression on the protein level of p-Akt, Akt and caspase-3/9 were determined by Western blotting.The generation of Aβ42 in the cells was measured by ELISA.RE-SULTS:The cell survival rate was remarkably increased after transfection with NGB compared with control group and emp-ty plasmid group (P<0.05).The over-expression of NGB significantly inhibited the decrease in mitochondrial membrane potential induced by pAPPswe.The over-expression of NGB inhibited the apoptosis of the cells.Furthermore, over-expres-sion of NGB not only inhibited the expression of caspase-3 and caspase-9, but also induced the production of p-Akt, which was prevented by LY294002, an inhibitor of PI3K/Akt.The generation of Aβ42 was inhibited in the cells with the over-ex-pression of NGB.CONCLUSION: Over-expression of NGB significantly inhibits the SH-SY5Y cell injuries induced by pAPPswe and inhibits the expression of caspase-3/9, which is tightly related with cell apoptosis.Furthermore, the neuro-protective roles of NGB may be via activating PI3K/Akt signaling pathway.

OBJECTIVETo compare the clinical efficacy difference between electroacupuncture (EA) at qijie area combined with spine balance-regulating massage and medication for posterior circulation ischemia (PCI).

METHODSOne hundred cases of PCI were randomly divided into a treatment group (50 cases) and a medication group (50 cases). The treatment group was treated with EA at Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shenshu (BL 23), Danzhong (CV 17), etc. in qijie area combined with spine muscle-relieving massage and comprehensive chiropractic. The medication group was treated with oral administration of nimodipine (30 mg per time, three treatments per day) and vinpocetine injection with 500 mL of glucose injection or intravenous drip of 500 mL 0.9% sodium chloride injection, once a day. Ten treatments were taken as one course in both groups, and two courses were given. The symptom score, mean resistance index (RI) of vertebral artery (VA) and basilar artery (BA), mean velocity of blood flow (Vm) and comprehensive clinical efficacy were compared before and after treatment in two groups.

RESULTSThe cured and markedly effective rate was 79.6% (39/49) in the treatment group, which was superior to 54.7% (23/42) in the medication group (P<0.05). The symptom score was both significantly improved after treatment in two groups (both P<0.05), which was more obvious in the treatment group (P<0.05). The RI of VA and BA, Vm of VA and BA were significantly improved after treatment in two groups (all P<0.05), which were more obvious in the treatment group (all P<0.05).

CONCLUSIONThe electroacupuncture combined with spine balance-regulating massage has superior effect on improving mean velocity of blood flow and resistance index of vertebral artery and basilar artery as well as symptom score to medication, and is believed to be a safe and effective treatment for posterior circulation ischemia.

Bioimprinting is a new developed technique to improve the characteristics of enzymes.Bioimprinting by lauric acid was conducted to improve the esterification activity of lipase PS in sol-gel immobilization process with methyltrimethoxysila(MTMS) and tetramethoxysila(TMOS) as the precursors.Results generated by checking the esterification activity and scanning electron microscope showed that bioimprinting can enhance the specific activity and thermal stability of lipase PS.The bioimprinting system was optimized by orthogonal experiment,and the optimal condition for lipase bioimprinting is water/silane molar ration(R) 12,polyethylene glycol(PEG) 120?l,and lauric acid 0.15 mmol.Compared with the free enzyme and the non-imprinted enzymes,the specific activity of imprinted enzymes has been improved 44.3 fold and 2.4 fold,respectively.Imprinted lipase show better thermal stability,and the relative activity is 58% after incubated in 80 ℃ for 0.5 h,while no activity was detected for the free enzyme.

Objective To investigate the role of negative-regulatory factors of toll-like receptors (TLRs)signal pathways in immunological pathogenesis of Kawasaki disease(KD).Methods Thirty-two chil- dren with Kawasaki disease and 16 age-matched healthy children were studied.Reverse-transcription PCR (RT-PCR)and real-time PCR were used to evaluate the mRNA expression levels of toll-like receptor 4(TLR4), MD-2,MyD88,IRAK-4,TRAF6,T1/ST2,IRAK-M,Triad 3A,and proinflammatory factors such as IL-1?, IL-6,IL-8 and TNF-?,in peripheral blood monocytes/macrophages(MC).The expression of TLR4 protein in MC was analyzed by flow cytometry.Results①Compared with the control group,the mRNA levels of TLR4, MD-2,MyD88,IRAK-4 and TRAF6 in KD group were up-regulated significantly(P＜0.01),and the expression level of TLR4 protein was also found to be up-regulated in KD group during acute phase.It was detected that expression levels of TLR4 protein in KD with coronary artery lesion(KD-CAL~+)was significantly higher than that of KD without coronary artery lesion(KD-CAL-)[flow cytometry:(6.5?1.7)% vs(11.9_+2.4)%,P＜0.01].②The expression level of negative-regulatory factors such as IRAK-M and Triad3A were significantly up-regulat- ed in acute phase of Kawasaki disease,while the mRNA levels of IRAK-M and Triad3A in KD-CAL~+ group was found to be significantly lower than those of KD-CAL~- group(P＜0.01).No difference of T1/ST2 mRNA expres sion level was detected among all groups(P＞0.05).③The expressions of proinflammatory eytokines such as IL-1?, IL-6,IL-8 and TNF-?in monoeytes/macrophages during acute phase of Kawasaki disease were higher than those of the control group(P＜0.01),and expression of proinflammatory cytokines in KD-CAL~+ group was significantly higher than that of KD-CAL~- group.Conclusion Relative insufficient expression of negative-regulatory factors, such as IRAK-M and Triad3A,maybe correlate with immunological pathogenesis of Kawasaki disease.

Objective: To understand the effect of dobutamine on the integrated backscatter of myocardium. Methods: Nineteen open chest dogs were detected by HP Sonos 5500 with S8 transducer, and the WT, AIBS and CVIB were measured before and after the dobutamine stress. Results: During the dobutamine stress, following the increase of WT, the transmural, subepicardial and subendocardial CVIB all increased. And the increase of subepicardial CVIB was greater than that of subendocardial CVIB, leading to the decrease of TGI. But the AIBS didn't change significantly in the whole process. Conclusion: Dobutamine can enhance myocardium CVIB but has no obvious infleunce on AIBS. [

Some studies indicate that adipose derived stem cells (ADSCs) can differentiate into adipogenic, chondrogenic, myogenic, and osteogenic cells in vitro. However, whether ADSCs can be induced to differentiate into neural cells in vitro has not been clearly demonstrated. In this study, the ADSCs isolated from the murine adipose tissue were cultured and transfected with the EGFP gene, and then the cells were induced for neural differentiation. The morphology of those ADSCs began to change within two days which developed into characteristics of round cell bodies with several branching extensions, concomitantly expressing EGFP fluorescence. Approximately 60% of the total cell populations were bipolar or multipolar in shape. Some of them appeared to make contact with their neighboring cells. RT-PCR, Western blot and Immunocytochemistry revealed that the expression levels of the markers of neurons and oligodendrocytes such as MAP2, NF-70, Neu N and RIP upon neural induction were increased, but the expression of the special marker of astrocytes, GFAP, was undetectable until 96 h after induction when a small signal was observed. It was concluded that the ADSCs transfected with EGFP possessed the ability to undergo morphologic and phenotypic changes consistent with neural differentiation in vitro. It suggests that these cells might provide an ideal source for further stem cell research with possible therapeutic application for spinal cord injury.
