Objective:To observe the therapeutic effect of Governor Vessel-unblocking and yang-regulating acupuncture plus chiropractic treatment on upper cervical spondylosis. Methods:A total of 64 eligible cases were randomly allocated into an observation group (n=32) and a control group (n=32) according to the random digital table. Cases in the observation group were treated with Governor Vessel-unblocking and Yang-regulating needling method, fine adjustment of the upper cervical spine and lumbosacral Ban-pulling manipulation; cases in the control group were treated with routine acupuncture and same spinal adjustment as the observation group. The treatment was done once a day in both groups. The therapeutic efficacies were observed after 10 times of treatment. Results:The total effective rate was 78.1% in the observation group and 67.5% in the control group. The difference in the total effective rate between the two groups was statistically significant (P<0.05). Conclusion:Governor Vessel-unblocking and yang-regulating acupuncture and regulate yang plus chiropractic therapy is better than routine acupuncture plus chiropractic therapy in the therapeutic effect in the treatment of upper cervical spondylosis.

Objective To investigate the clinical efficacy of S-1 combined with cisplatin in the treatment of old patients with advanced gastric cancer.Methods 85 patients were randomly divided into two groups.Experimental group was treated by S-1 combined with cisplatin,while control group was treated by 5-FU and cisplatin.Short-term efficacy and adverse reactions were evaluated after four cycles.Results All patients had succcssfully accomplished chemotherapy.Compared with the control group ( RR =52.4％,DCR =81.0％ ),RR and DCR in experimental group ( RR =67.4％,DCR =93.0％ ) had statistically significant difference ( P ＜ 0.05 ).The top three of adverse reactions and complications in patients of the two groups were:nausea and vomiting,low WBC,low hemoglobin concentration.Compared with the control group,the toxicity in experimental group had no statistically significant difference ( P ＞0.05).All patients were followed up with a meau of( 15.5 - 2.7 ) months.The 1 year survival rate was 60.5％(26/43) in the experimental group; the 1 year survival rate was 52.4％ (21/42) in the control group.There was no statistically significant difference( P ＞ 0.05 ).Conclusion The S-1 combined with cisplatin had shown better efficacy in the treatment of old patients with advanced gastric carcinoma,and the toxicity was relatively mild and tolerable.

Objective To study the effect of astrocyte on synapse formation and the molecular mechanism. Methods Cortical astrocytes were isolated and purified from neonatal rats.On the 2h,7th day,14th day and 21th day after passage,we counted the number of astrocytes and the culture medium(astrocyte-conditioned medium,ACM)was harvested to measure the concentration of estrogen(E 2)by using ELISA techniques.Based on the model of pure culures of neonatal cortical neurons,the experimental groups were designed as follows:1.pure neuron cultures(group N);2.ACM cultures(group A);3.mixed cultures(group M);4.E 2 cultures(group E 2);5.ACM+Tamoxifen(estrogen receptor antagonist)cultures(group A+T);6.Tamoxifen cultures(group T).Then synaptic puncta in every group was stained and counted through immunofluorescence,and we also compared the differences in puncta number among those six groups(at 9th day in culture,number/per neuron). Results The numbers of astrocytes were:1?10 4/ml, 1.1?10 6/ml, 1.4?10 6/ml, 1.5?10 6/ml; The concentrations of E 2 were:(ng/L):0, 117?22, 266?22,252?27 respectively.No estrogen was detected in the primary culture medium.The concenteration of estrogen increased in correspondence with the culturing days and reached the peak around at the 14th day, then decreased gradually but kept at a certain high level,and the numbers of synaptic puncta of per neuron in group N,A,M,E 2,A+T,T were:14?3;79?5;83?8;80?6;32?3;29?3 respectively.The treatment of pure neuron culture with ACM increased the number of synapses on per neuron by up to 6 fold by comparison with pure neuronal culture.Exogenic estradiol added into pure neurons can mimick the effect of the ACM.Tamoxifen which is antagonist of estrogen receptor could decrease the effect of ACM by 75%.Conclusion The astrocytes of neonatal rat cortex do secrete E 2.Astrocyte-derived estrogen may be the molecule regulating the synaptic formation through estrogen receptors.
