Clinical observation on electroacupuncture combined with rehabilitation techniques for treatment of shoulder subluxation after stroke / 中国针灸

<p><b>OBJECTIVE</b>To compare the therapeutic effect difference between electroacupuncture combined with rehabilitation techniques and simple rehabilitation techniques for treatment of the shoulder subluxation after stroke.</p><p><b>METHODS</b>Sixty cases of shoulder subluxation patients were divided into an acupuncture combined with rehabilitation group (30 cases) and a rehabilitation group (30 cases). The acupuncture combined with rehabilitation group was treated with electroacupuncture at Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) etc. combined with rehabilitation treatment, the rehabilitation group was treated with rehabilitation only. The therapeutic effects were evaluated and the pain score of the shoulder joint, passive range of motion of shoulder joint, the muscle strength of middle group of the deltoid and the function grade of the upper limbs motion of the two groups were evaluated before and after treatment.</p><p><b>RESULTS</b>The acupuncture combined with rehabilitation group was superior to that of the rehabilitation group in pain score of the shoulder joint, passive range of motion of shoulder joint, the muscle strength of middle group of the deltoid and the function grade of the upper limbs motion with significant differences between the two groups (all P<0.05); the total effective rate of 93. 3% in the acupuncture combined with rehabilitation group was superior to that of 73.3% in the rehabilitation group (P<0.05).</p><p><b>CONCLUSION</b>The therapy of electroacupuncture combined with rehabilitation techniques can act a good regulating role on muscle strength and the muscular tension of shoulder joint and the muscles around the scapula through many steps, and can effectively improve the shoulder subluxation.</p>

Combination of lamivudine with thymosin alpha1 in treatment of duck hepatitis B / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To explore the inhibitory effect of combination of lamivudine with thymosin alpha1 (Talpha1) on the replication of duck hepatitis B virus (DHBV).</p><p><b>METHODS</b>Peking ducks of 1 d old were challenged with DHBV-positive serum and used as a duck hepatitis B model. After treated with lamivudine for three months, the ducks were randomly grouped and treated with or without Talpha1 for 8 d. Serum DHBV titrate was observed by semi-quantitative PCR, and inflammation and degeneration of hepatocytes were observed by pathology examination.</p><p><b>RESULTS</b>The serum DHBV titrate was significantly reduced (4483.2+/-5193.4 compared with 9351.8+/-5059.6) after lamivudine treatment, and it was reduced more significantly(1692.2+/-589.2) after combination treatment with Talpha1. Lamivudine reduced the degeneration degree of hepatocytes (3.2+/-0.8 compared with 4.6+/-0.5) and the inflammation degree of liver (6.2+/-3.3 compared with 8.6+/-2.8). The combination treatment with Talpha1 increased liver inflammation degree (9.0+/-5.2).</p><p><b>CONCLUSION</b>Both Talpha1 and lamivudine may reduce the replication of DHBV in Peking ducks and combination treatment may have the better anti-virus effect and enhance immune response in liver.</p>

Immunomodulatory function of orally administered thymosin alpha1 / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

<p><b>OBJECTIVE</b>To investigate the immunological function of a yeast expression system for thymosin alpha1 (Talpha1).</p><p><b>METHODS</b>A constructed Talpha1 yeast expression system was used to investigate the immunological function of orally administered Talpha1. Dried yeast containing three different concentration of Talpha1 was fed to normal Balb/c mice and other Balb/c mice whose immunities were inhibited in advance by cyclophosphamide. Synthesized Talpha1 peptide was used as positive control and dried yeast with empty plasmid was used as negative control. CD4(+) and CD8(+) levels were detected by flow cytometry assay. TNF-alpha, IFN-gamma, IL-2, IL-6 and IL-10 levels were detected by liquid chip.</p><p><b>RESULTS</b>In normal Balb/c mice or immune inhibition Balb/c mice, CD8(+) levels were significantly increased. Especially in immune inhibition Balb/c mice, CD8(+) levels in synthesized Talpha1 group (18.77%+/-4.72%), small dose group (13.48%+/-6.17%) and large dose group (22.74%+/-1.09%) were significantly higher than that in empty yeast control group (7.49%+/-2.14%).</p><p><b>CONCLUSION</b>Orally administered Talpha1 has its certain immunomodulatory function.</p>

Construction of a eukaryotic expression plasmid of Humanin / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

<p><b>OBJECTIVE</b>To construct a eukaryotic expression plasmid pcDNA3.1(-)-Humanin.</p><p><b>METHODS</b>The recombinant plasmid pGEMEX-1-Humanin was digested with restriction endonucleases BamH I and Hind III and the Humanin gene fragments, about 100 bp length, were obtained. Then the Humanin gene fragments were inserted into eukaryotic expression vector pcDNA3.1(-) and the recombinant plasmids pcDNA3.1(-)-Humanin were identified by sequencing.</p><p><b>RESULTS</b>Recombinant plasmid DNA successfully produced a band which had the same size as that of the Humanin positive control. The sequence of recombinant plasmids accorded with the Humnain gene sequence.</p><p><b>CONCLUSIONS</b>A eukaryotic expression plasmid of Humanin was successfully constructed.</p>
