OBJECTIVE:To observe the clinical efficacy and safety of sodium hyaluronate combined with glucosamine in the treatment of knee osteoarthritis. METHODS:1 220 patients with knee osteoarthritis were randomly divided into observation group and control group. The patients in control group were treated with Sodium hyaluronate injection alone,once a week;while the ob-servation group was additionally and orally treated with Glucosamine hydrochloride capsules two tablets,three times a day. The course of treatment was 5 weeks in both groups. The relevant physicotherapeutics and oral medication in the treatment of the dis-ease should be stopped. The clinic efficacy,visual analog scale(VAS)and lysholm knee score before and after treatment,and inci-dence of adverse reaction were observed. RESULTS:Total effective rate of observation group was significantly higher than control group,with statistically significant difference(P<0.05). After treatment,VAS and lysholm knee scores in both groups were signifi-cantly lower than before,and observation group was lower than control group,with significant differences(P<0.05). There were no severe adverse reactions during treatment. CONCLUSIONS:Sodium hyaluronate combined with glucosamine has more signifi-cant clinical efficacy in the treatment of knee osteoarthritis than sodium hyaluronate alone,with good safety.

Objective To investigate whether nimodipine could reduce complications after microvascular decompression in patients with hemifacial spasm. Methods 220 patients with hemifacial spasm , admitted into our hospital from May 2011 to Oct. 2013 , were all treated by microvascular decompression. They were divided randomly into two groups. Patients in the treatment group were treated with nimotop 50 mg/d after the operation for the first 3 days, then was orally taken 30 mg/d for a week. Patients in the control group were treated with the same after the operation without nimodipine. The postoperative complications including hearing deficit and peripheral facial paralysis were closely observed within three months after operation. Results The total effective rate was 100% in both groups. The incidence rate of peripheral facial paralysis and hearing deficit in treatment group was significant lower than that of the control group (P < 0.05). Conclusion Nimodipine has significant effect on reducing the incidence rate of peripheral facial paralysis and hearing deficit after microvascular decompression in patients with hemifacial spasm.

Objective To construct a recombinant plasmid DNA containing herpes simplex virus type 1(HSV-1) glycoprotein D (gD) gene.Methods The HSV-1 gD gene was obtained by polymerase chain reaction (PCR) and inserted into TA cloning vector pGEM-T, then cloned into the eukaryotic expression vector pcDNA3.1 to generate pLy-D. The recombinant plasmid pLy-D, which was confirmed by partial sequencing and restriction endonuclease analysis, was transfected into Cos-7 cells and used to inoculate ICR mice via muscular injection. Immunohistochemistry and enzyme-linked immunoabsorbent assay (ELISA) were employed to test the gD expression in transfected cells and the specific anti-HSV-1 antibody in the serum of immunized mice, respectively.Results The gD eukaryotic expression plasmid pLy-D was constructed. Using the immunohistochemistry technique, the gD expression in pLy-D-transfected cells was detected. The ELISA demonstrated that specific anti-HSV-1 antibody could be induced in immunized mice after three times injection.Conclusions We constructed HSV-1 gD eukaryotic expression plasmid pLy-D which could express gD protein in transfected cells and could induce humoral immune response in mice. This observation will be helpful in designing HSV prophylactic vaccine.

OBJECTIVETo compare the clinical therapeutic effects on intractable facial paralysis among acupuncture, acupoint catgut embedding and PDS embedding.
METHODSTwo hundred and seventy-nine patients of intractable facial paralysis were randomized into an acupuncture group, a catgut embedding group and a PDS embedding group, 93 cases in each one. Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Xuanlu (GB 5), Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Qianzheng (Extra), Xiaguan (ST 7) and Fengchi (GB 20) on the affected side and bilateral Hegu (LI 4) and Zusanli (ST 36) were selected in the three groups. In the acupuncture group, acupuncture was applied to those acupoints, once every two days; 10 treatments made one session; the successive three sessions were required. In the catgut embedding group and the PDS embedding group, catgut and PDS were embedded separately, once every 10 days; 3 treatments made one session and the successive two sessions were required. The therapeutic cycle was 2 months in the three groups. The therapeutic results were analyzed statistically 2 months later. The scores of Sunnybrook facial nerve grading system and the facial nerve electroneurography (ENoG) were used for the efficacy assessment before and after treatment in the three groups.
RESULTSAfter treatment, the score of Sunnybrook facial nerve grading system was improved apparently after treatment as compared with that before treatment in any of the three groups (all P < 0.05). The score in either of the embedding groups was better than that in the acupuncture group (both P < 0.05). The difference was not significant between the catgut embedding group and the PDS embedding group (P > 0.05). After treatment, ENoG wave ampli tude values in the frontal muscle and orbicularisoris muscle on the affected side were improved as compared with those before treatment in the three groups (all P < 0.05). Those in the catgut embedding group and the PDS embedding group were better than those in the acupuncture group (all P < 0.05), and had no significant difference as compared with those on the healthy side (P > 0.05). In the acupuncture group, ENoG wave amplitudes on the affected side were lower than those on the healthy side (both P < 0.05).
CONCLUSIONAcupuncture, catgut embedding and PDS embedding at acupoints all achieve the therapeutic effects on intractable facial paralysis. However, the acupoint embedding therapy presents more advantages on the recovery of facial nerve function. The efficacy is similar between the catgut embedding and the PDS embedding.
