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.

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.

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 .

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.

Objective To study the effect of magnetic stimulation on the expression of B cell lymphoma/leukemia gene 2 ( Bcl-2 ) and caspase-3 genes, and the apoptosis of neurons in rats with spinal cord injury (SCI).Methods Sixty rats were randomly divided into a magnetic stimulation group, a model group and a sham-operation group. An SCI model was established in the magnetic stimulation and model groups. The magnetic stimulation was applied at the 6th, 12th, 24th and 72nd hour after the operation to the rats in the magnetic stimulation group, and sham magnetic stimulation was given to the model group and sham-operation group rats at the same time points. Two hours after treatment, 5 rats of each group were sacrificed and their injured spinal cords were sectioned. The gene expressions were detected using immunohistochemical techniques, and apoptosis of neurons was observed by the TUNEL method. Results Few apoptotic cells were found in the sham-operation group, but more were found in the model group. Apoptotic cells in the magnetic stimulation group were significantly fewer than in the model group. The expression of both Bcl-2 and caspase-3 in the magnetic stimulation and model groups was significantly higher than in the sham-operation group at the different time points. Expression of Bcl-2 in the magnetic stimulation group was significantly higher than in the model group, but expression of caspase-3 in the magnetic stimulation group was significantly lower than in the model group. Conclusions Magnetic stimulation up-regulates the expression of Bcl-2 genes and down-regulates the expression of caspase-3 in injured neurons. Magnetic stimulation might have protective and rehabilitative effects after human SCI.
