BACKGROUND:Elderly patients with degenerative lumbar degeneration often appear insufficient holding power of pedicle screw in spine surgery, which is prone to occur de-pinning and leads to insecure fixation. How to increase the holding power of screws has become a hot research. OBJECTIVE:To observe the early clinical effect of pedicle screws with cement augmentation for treating lumbar degenerative diseases in elderly patients. METHODS:A total of 65 old patients with lumbar degenerative diseases received a treatment between August 2012 and April 2014, and were divided into two groups according to the treatment strategy:treatment group (n=24;internal fixation of pedicle screws with cement augmentation) and control group (n=41;routine internal fixation of pedicle screws). General conditions of patients in two groups were observed and compared. Visual analog scale (VAS) and Japanese Orthopaedic Association (JOA) score system were used for evaluating the lumbar and back pain, and restoration of neurological function in lower limbs respectively. RESULTS AND CONCLUSION:Al of the patients successful y received the surgery and then were fol owed up from 3 to 20 months. The anterioposterior and lateral X-ray film revealed no loosening, loss, fracture of the screws, and no loss of intervetebral space height was found. There was no significant difference in the blood loss and hospital stay between two groups (P>0.05). JOA at postoperative 3 and 6 months, and VAS score at postoperative 3 months were significantly improved after the treatment of pedicle screws with cement augmentation, when compared to control group (P<0.05). VAS scores showed no difference at 6 months postoperatively in two groups (P>0.05). Pedicle screws with cement augmentation for treating lumbar degenerative diseases have the advantages of improving the screws holding strength, reconstructing the stability of lumbar vertebra and obtaining clinical efficacy on degenerative spine.

OBJECTIVETo investigate the application of microsurgical technique in the replantation of amputated ear.

METHODS7 cases of amputated ears were analyzed from June 2009 to April 2015 in our department. We used microsurgical technique to anastomose about five vessels and nerves. The blood supply of auricle was restored within three to six hours. All subjects underwent treatments including anti-freezing, anti-spasm and anti-infection treatment after the emergency surgery.

RESULTS7 amputated ears were all survived after replantation. The patients were followed up for one month to six months ( average for 28 months). The appearances of survived ears body were fully recovered without any significant atrophy or pigmentation. The sensory function of ears recovered to normal after 1 year.

CONCLUSIONSThe application of microsurgical technique in the replantation of amputated ear can expect the high success rate of ear replantation. However, skilled and high-quality anastomosis technique of small vascular are required.

Objective To investigate the clinical effect and safety of spleen-preserving surgery by microwave tissue coagulation (MTC) therapy.Methods Retrospectively analyzed the clinical data of 45 cases undergoing spleen retaining surgery by MTC therapy (observation group) and comparative study was used on another 45 cases experiencing splenectomy (comparative group),clinical effect and complications were compared.All cases were patients from Jan.2010 to Jun.2013.Results All cases were cured.Hospitalization of observation group is obviously shorter than that of comparative group(P =0.007).The rate of complication in observation group(4.44％) is lower than that in comparative group (20.00％),but the time and amount of bleeding in operation of observation group is much more than that of comparative group.Conclusion MTC can effectively guarantee patients safety,shorten hospital stay,and be worthy of popularization.

BACKGROUND: Ankle fracture combined with deltoid ligament rupture and distal tibiofibular syndesmosis injury occurs occasionally. Its treatment with distal tibiofibular syndesmosis screw fixation or deltoid ligament repair remains controversial. The former appears with poor reduction, broken nails, secondary surgery and other problems.OBJECTIVE: To observe the clinical effectiveness of suture anchor repair for ankle fracture combined with deltoid ligament injury.METHODS: Twelve patients with ankle fracture combined with deltoid ligament injury were selected from the First Affiliated Hospital of Guangzhou University of Chinese Medicine between January 2013 and December 2015. All patients were treated with open reduction, internal fixation, and anchor repair, but without distal tibiofibular syndesmosis screw fixation. The curative efficacy and joint stability were observed.RESULTS AND CONCLUSION: (1) All patients were followed-up for more than 12 months. (2) The modified Baird-Jackson scoring system showed excellent in nine cases, good in two cases, average in one case, poor in none case, and the excellent and good rate was 92%. (3) At 1 year after internal fixation, the X-ray examination showed the malleolus gap and talus slope angle of the affect side were (3.47±0.12) mm and (0.45±0.18)°, and the malleolus gap and talus slope angle of the healthy side were (3.44±0.05) mm and (0.43±0.14)°, and there was no significant difference between two sides (P > 0.05). (4) These results indicate that the suture anchor can repair the anatomy and biomechanics of deltoid ligament with stable ankle joint, and secondary surgery is unnecessary.

ObjectiveTo investigate the mechanism and the protective effect of heat shock protein 27 (HSP27) on rat cardiomyocytes when ischemic preconditioning performed.MethodsCultured rat cardiomyocytes were divided into four groups: control group, ischemic group,ischemic preconditioning group and cyclohexamide group. Cell viabilities were analyzed by MTT. The apoptosis was evaluated with DNA ladder and flow cytometry Annexin V Flous staining. Western Blot was used to determine the expression of HSP27 and caspase-3 in cardiomyocytes.ResultsIschemic preconditioning could improve cell viability. The apoptosis ratio in ischemic preconditioning group was significantly less than that in ischemic group. These were accompanied by an increase in the expression of HSP27 and a decrease in caspase-3. The expression of the increased HSP27 and the protective effect induced by ischemic preconditioning were completely abolished by the presence of cycloheximide, a translation inhibitor.ConclusionThe expression of HSP27 induced by ischemic preconditioning plays an important role in protecting cardiomyocytes, and the mechanism is possibly related to the inhibition of cell apoptosis.

Objective To study the effect of comprehensive Chinese medicine therapy,including Chinese herbal medicine fumigation,massage,and quadriceps exercise,on adipokines of visfatin and chemerin content in joint fluid of patients with knee osteoarthritis (KOA),and to explore its possible therapeutic mechanism for KOA.Methods A total of 60 cases of KOA patients were randomly divided into treatment group and control group,30 cases in each group.The treatment group was treated with comprehensive Chinese medicine therapy,and the control group was treated with Chinese medicine fumigation alone.After treatment for 2 weeks,the clinical efficacy of both groups was evaluated,and the changes in the scores of the Western Ontario and McMaster Universities Arthritis Index (WOMAC)were observed.Moreover,the contents of visfatin and chemerin in jointfluid were examined.Results (1) The total effective rate of the treatment group was 96.7％ and that of the control group was 83.3％,the difference being significant (P ＜ 0.01).(2) After treatment,WOMAC scores of both groups were obviously decreased(P ＜ 0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group (P ＜ 0.01).(3) The contents of visfatin and chemerint in joint synovial fluid of both groups were decreased (P ＜ 0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group(P ＜ 0.05).Conclusion The comprehensive Chinese medicine therapy of Chinese herbal medicine fumigation,massage and quadriceps exercise is effective for the treatment of KOA,and can decrease the contents of visfatin and chemerin in joint fluid of KOA patients,which may be one of its therapeutic mechanisms.

The purpose of this study was to investigate the effects of porcine interleukin (IL)-2 and IL-4 genes on enhancing the immunogenicity of a porcine reproductive and respiratory syndrome virus ORF5 DNA vaccine in piglets. Eukaryotic expression plasmids pcDNA-ORF5, pcDNA-IL-2, and pcDNA-IL-4 were constructed and then expressed in Marc-145 cells. The effects of these genes were detected using an indirect immunofluorescent assay and reverse transcription polymerase chain reaction (RT-PCR). Characteristic fluorescence was observed at different times after pcDNA-ORF5 was expressed in the Marc-145 cells, and PCR products corresponding to ORF5, IL-2, and IL-4 genes were detected at 48 h. Based on these data, healthy piglets were injected intramuscularly with different combinations of the purified plasmids: pcDNA-ORF5 alone, pcDNA-ORF5 + pcDNA-IL-2, pcDNA-ORF5 + pcDNA-IL-4, and pcDNA-ORF5 + pcDNAIL-4 + pcDNA-IL-2. The ensuing humoral immune responses, percentages of CD4+ and CD8+ T lymphocytes, proliferation indices, and interferon-gamma expression were analyzed. Results revealed that the piglets co-immunized with pcDNA-ORF5 + pcDNA-IL-4 + pcDNA-IL-2 plasmids developed significantly higher antibody titers and neutralizing antibody levels, had significantly increased levels of specific T lymphocyte proliferation, elevated percentages of CD4+ and CD8+ T lymphocytes, and significantly higher IFN-gamma production than the other inoculated pigs (p < 0.05).
