Objective: To study the effect of bilirubin on the functional changes of sarcoplasmic reticulum (SR) induced by acute exercise. [WT5FZ]Methods:[WT5BZ] 41 Wistar male rats were divided into five groups, control group, exercise group, exercise recovery group, bilirubin treated exercise group and bilirubin treated exercise recovery group. The rats were administered with 1 ?mol/kg body weight of bilirubin or saline once every day for 4 weeks. After swimming with load for 2 h, all of the rats were killed and several indices were determined. [WT5FZ]Results:[WT5BZ] Bilirubin could inhibit the decrease of Ca 2+ content and the increase of Ca 2+ ,Mg 2+ ATPase activity in SR induced by acute exercise, and inhibit the increase of Mg 2+ content in cytoplasm. [WT5FZ]Conclusion:[WT5BZ] Bilirubin may delay the development of fatigue induced by acute exercise through protecting certain functions of SR.

Objective To study the effects of parecoxib sodium combined with continuous femoral nerve block on the balance of Th1/Th2 in elderly patients after total knee arthroplasty. Methods Fifty elderly patients,33 males and 1 7 females,aged 65 to 80 years,with ASA Ⅰ or Ⅱtreated with total knee arthroplasty were randomly divided into two groups (n =25 each):parecoxib sodium combined with continuous femoral nerve block group (group A)and parecoxib sodium com-bined with intravenous analgesia group (group B).Quick induce laryngeal mask anesthesia and intra-venous parecoxib sodium 40 mg at 30 min before skin incision were adopted in both groups.After the first 8 h,parecoxib sodium of 40 mg was intravenously injected again.The patients in group A re-ceived femoral nerve puncture and continuous electronic analgesia pump.The patients in group B re-ceived postoperative intravenous electronic analgesia pump.Visual analogue score(VAS)during rest and movement at 6,12,24,36,48 h after operation,side effects in two groups were recorded,venous blood samples were taken before anesthesia (T0 ),at the end of operation (T1 ),and 24 h(T2 ),48 h (T3 ),72 h (T4 )after operation for determination of plasma IFN-γ,IL-10 and cortisol (Cor). Results The values of VAS were significantly lower in group A compared with group B in rest at 6, 12 h after operation,the values of VAS were significantly lower in group A compared with group B in moving at every time points after surgery (P <0.05 ).The plasma Cor concentrations were signifi-cantly increased at T1-T3 compared with baseline value at T0 in two groups(P <0.05 ).The plasma Cor concentrations in group A were significantly decreased compared with group B at T1-T3 (P <0.05).The plasma IFN-γconcentrations were significantly lower at T2 and T3 compared with baseline value at T0 in group A,the plasma IFN-γ concentrations were significantly lower at T2-T4 compared with baseline value at T0 in group B (P <0.05),the plasma IFN-γ concentrations were significantly increased in group A compared with group B at T2-T4 (P <0.05 ).The plasma IL-10 concentrations were significantly increased compared with baseline value at T1-T4 in two groups (P < 0.05 ),the plasma IL-10 concentrations were significantly decreased in group A compared with group B at T1-T4 (P <0.05).Compared with group B,the incidence of postoperative nausea,vomiting and pruritus in group A was lowered significantly (P <0.05).Conclusion Parecoxib sodium combined with continu-ous femoral nerve block on postoperative pain in elderly patients after total knee arthroplasty can a-chieve good effect of postoperative analgesia and fewer complications, lower cortisol secretion, slowing down the decrease of IFN-γ secretion and the increase of IL-10 secretion.This method could effectively protect the immune function of patients undergoing arthroplasty.

Objective: To investigate the mechanism underlying the repairing effect of Flk-1+ MSC on injury.Methods: We established the mouse model of acute renal ischemia-reperfusion,perfused murine Flk-1+ MSC within 1 hour or after 10 days in the acute and chronic groups,respectively,determined the homing of GFP positive Flk-1+ MSCs and the percentage of proliferating cells in the injured renal tissues by immunohistochemistry,and identified chronic fibrosis after injury by Masson trichrome staining. Results: Tissue injury and inflammation were significantly alleviated in the acute group,exhibiting a good long-term recovery,but no significant improvement was observed in the chronic group.The number of PCNA positive cells reached the peak at 3 days in the acute group,as compared with 10 days in the control,indicating that MSC engraftment effected an earlier endogenous repair.GFP staining showed that most of the MSCs homed to the interstitial region and the rest to the renal tubule.Conclusion: Flk-1+ MSC has a repairing effect on renal injury via alleviating acute inflammation and launching endogenous repair,while direct differentiation from Flk-1+ MSC is not the primary mechanism of its therapeutic efficacy.

Objective To explore the protective affect of individual earmuffs in microtia reconstruction using tissue expander.Methods 95 patients performed the implantation of tissue expander had been grouped into the experimental group(49 cases)and the control group(46 cases).Patients in the experimental group wore individual earmuffs,whereas patients in the control group wore traditional earmuffs.The survey including the information of patients' experience in wearing the earmuffs was carried out on the day when patients were given auricular reconstruction.Data collected from the two groups were analyzed to evaluate the aspects of permeability and safety.Results Patients in the experimental group complained less discomfort in sultry in permeability and tinnitus than patients in the control group.From the perspective of safety,there was no complaints of mosquitoes climbing into the earmuffs from the two groups.Because of the good adhesiveness of the individual earmuffs to the skin,the incidence of redness of skin in the experimen tal group was significantly lower than that in the control group.Conclusions Individual earmuff is a safe and comfortable nursing appliance which is practical for clinical application because of its good permeability,adhesiveness and less incidence of redness of skin.

BACKGROUND: Immunoloregulation of mesenchymal stem cells (MSCs) is commonly approved. Previous studies have confirmed the ability of Flk-1~+ bone marrow MSCs (BMSCs) to inhibit T/B lymphocyte proliferation in vitro. OBJECTIVE: To investigate the therapeutic effect of Flk-1~+ BMSCs in collagen-induced arthritis mice.METHODS: A total of 18 healthy male DBA-1(H-2K~q) mice aged 10 weeks were randomly divided into 3 groups. All the mice were injected at the base of the tail with bovine type II collagen (CII), and received a booster injection of CII on day 21 to establish the CIA mice model. DBA-1(H-2K~q)mouse Flk-1~+ BMSCs were isolated in vitro by the density gradient centrifugation and adherence screening. Following initial immunity, mice in the cell transplantation group were infused with Flk-1~+ BMSCs (1-2)×106 cells/mouse via the caudal vein. Mice in the cell transplantation group were injected with the same volume of Flk-1~+ BMSCs during booster. Mice in the model control group were injected with an equal volume of saline 0 or 21 days following initial immunity. Following initial immunity and booster immunization, claw pad thickening and clinical score were observed, changes of joint pathology and dynamic changes in serum factor mass concentration were determined in mice. RESULTS AND CONCLUSION: Compared with the model control group, no significant difference in claw pad thickening and mean clinical score was detected in the cell transplantation group following initial immunity (P > 0.05), with the presence of obvious damage to synovial membrane and inflammatory cell infiltration. Mass concentration of each serum cell factor was similar. The claw pad was significantly thickened (P < 0.01), mean clinical score reached 3.35 points, with severe damage to synovial membrane, proliferation of blood capillary in the cell transplantation group following booster immunization. Interleukin-6 levels were greatly increased at day 28 following initial immunity (P < 0.1), but decreased at day 35 following initial immunity (P < 0.1). Results indicated that in the collagen-induced arthritis mouse models, Flk-1~+ BMSC transplantation did not obtain prospective therapeutic efficacy, but aggravation of arthritis was observed in the cell transplantation group following booster immunization. Upregulation of interleukin-6 concentration could aggravate the behavior symptom of rheumatoid arthritis mice.
