BACKGROUND:Hip and knee replacement is a common surgery in the clinic; the procedure is relatively complex; and the risk of surgery is relatively high, so that postoperative analgesia is not satisfactory. Perioperative pain management has been a clinical concern. To find safe and effective analgesia has become one of the important tasks of joint surgeons. OBJECTIVE:To investigate the effect of celecoxib on multi-mode analgesia after hip and knee replacement. METHODS: A total of 80 cases undergoing hip and knee replacement in the Chongqing Dongnan Hospital from September 2012 to September 2013 were enroled in this study. These patients were randomly divided into two groups. In the control group, celecoxib was not used for analgesia after replacement. In the experimental group, celecoxib was used after replacement. The pain was observed at 1-5 days after surgery in the two groups. When the analgesic pump was removed, the drug dosage and opioid analgesics use were recorded. Side effects of drug use were also recorded. RESULTS AND CONCLUSION:In terms of analgesic efficacy, the analgesic effect was better in the experimental group than in the control group (95%, 85%, P < 0.05). 95% patients in the experimental group were satisfied with the analgesia, which was significantly higher than in the control group (65%;P< 0.05). No significant difference in pain visual analogue scale score was detected between the two groups immediately, 4 and 5 days after surgery (P > 0.05). Pain visual analogue scale score was significantly lower in the experimental group than in the control group at 1, 2 and 3 days post surgery (P< 0.05). The drug dosage was significantly more in the experimental group than in the control group after surgery (P < 0.05). The frequency of opioid use in the experimental group was significantly lower than in the control group (P < 0.05). The complication rate was significantly lower in the experimental group (8%) than in the control group (18%) (P < 0.05). These findings demonstrate that the analgesic effect of celecoxib was ideal after hip and knee replacement using multi-mode analgesia, which can reduce the dose of analgesic drugs and have smal adverse reaction.

Objective To elucidate the effect of Ge-132 on the growth of melanocytes. Mothods Melanocyes from epidermis were cultured and purified ;the second generation of the cell was used for study ;the cells were divided into two groups randomly,to group A, Ge-132 was added to the media at 0.04mg/L ;to group B ,common culturing method was used without Ge-132. After 5d, the cells were seperated by digestion for study by transmission electronic micro- scope. ResultsCompared to group B, the vacuioes of the cells were increased,mitochondria distended, endoplasmic reticulum dilated and the number of melanosome declined in the group A. Conclusion Ge-132 can inhibit the melanocyte＇s growth at a certain concentration and might be used for treating pigmented diseases.

BACKGROUND: Adhesion molecules are closely associated with inflammation. Inflammation due to white blood cell (WBC) infiltration and free radical injury following brain ischemia are believed to be important factors contributing to the pathogenesis of multi-infarct dementia.OBJECTIVE: To determine the level of serum adhesion molecules and free radicals in patients with multi-infarct dementia to explore the relationship between their levels and multi-infarct dementia.DESIGN: A case-control trial.SETTING: Department of Neurology, Second Affiliated Hospital of Jilin University.PARTICIPANTS: Totally 82 patients with multi-infarct dementia were hospitalized in the Department of Neurology, Second Affiliated Hospital of Jilin University between January 2000 and December 2004. These patients included 32 cases of mild dementia, 21 of moderate dementia, and 29 of severer dementia. The normal controls were 23 concomitant healthy volunteers who came for routine physical examination.METHODS: Enzyme-linked immunosorbent assay (ELISA) and electron spin resonance were used to determine the level of serum soluble intercellular adhesion molecules (ICAM) and vascular cell adhesion molecules (VCAM), as well as oxygen free radical concentration in the normal controls and patients with multi-infarct dementia, and the association between the severity of the illness and the levels of adhesion molecules and oxygen free radicals was analyzed.MAIN OUTCOME MEASURES: Serum levels of ICAM-1 and VCAM-1 and oxygen free radical concentration in the two groups.RESULTS: Totally 82 patients with multi-infarct dementia and 23 healthy controls were included in this study and all enter the result analysis. In multi-infarct dementia patients, the serum levels of soluble ICAM-1 and VCAM-1 and oxygen free radical concentration [(469.00±76.33), (196.00± 45.91) and (1 103.30±98.96) μg/L, respectively] were significantly higher than those of the control group [(601.00±76.30), (4.018±1.656), and (1.295±0.718) μg/g, respectively, t=5.517-6.754, P ＜ 0.01], and the 3 indices were positively correlated with the severity of dementia (r=0.659 4,r=0.697 2, r=0.649 4, respectively, P ＜ 0.05); serum ICAM-1 and VCAM-1 levels were positively correlated with the concentration of oxygen free radicals (r=0.714 7, r=0.732 4, respectively, P ＜ 0.01).CONCLUSION: Serum ICAM-1, VCAM-1 and oxygen free radicals might be implicated in the pathophysiological development of multi-infarct dementia, and their levels increase in parallel with the severity of dementia.

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.
