Objective To investigate the effect oflevecamitine on nutrition,microinflammation status in ma-intenance hemodialysis (MHD) patients. Methods Forty two MHD patients were selected, who had undergone he-modialysis for at least two months before the study. One gram of levoeamitine was injecfed to the patients at the end of each dialysis treatment for six months. The parameters of inflammation stress were studied. Results After treatment with levocarnitine for six months, the average levels of dry body weight decreased markedly. ( P<0.05 ), The aver-age serum levels of C2reaetive protein (CRP),interleuldn26 (IL26) ,tumor necrosis factor2α(TNF2α), (P<0.01 ). Difference was not significant between serum lipid parameters before and after the treatment. Conclusion Intravenous supplement with levocamitine in MHD patients, appears to be associated with an improvement of nutrition and mieroinflammation status.

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 evaluate the efficacy of nasendoscopic resection of the inner wall of the maxillary sinus for the treatment of inverted papilloma of the nasal cavity and paranasal sinuses.Methods From January 2002 to December 2006,10 patients with nasal inverted papilloma received nasendoscopic resection of the inner wall of the maxillary sinus in our hospital.The clinical data of the patients were anlayzed retrospectively.Results The operation was completed in all the 10 cases.They were follwed up for 12 to 72 months with a mean of 30 months.Only one of the patients had recurrent papilloma in 1 year after the treatment.None of the patients devleoped epiphora.Conclusions Nasendoscopic resection of the inner wall of the maxillary sinus is feasible for patients with nasal inverted papilloma.By using the procedrue,facial scars can be avoided;moreover,owing to a clear surgical field,the surgeons can completely resect the tumor,and the patients have less trauma and low recurrence rate after the treatment.

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.

Aim To investigate the effects of starfish saponins(Sfs) on insulin signaling pathway in orotic acid-induced NAFLD rats.Methods 1% orotic acid was used to establish NAFLD model in male Wistar rats for six weeks.The NAFLD rats were randomly divided into two groups(eight rats in each group) and then fed with the corresponding diets: Model group(1% orotic acid)and Sfs group(1% orotic acid containing 0.04% starfish saponins).After starfish saponins feeding for 8 weeks, hepatic lipids content, liver function indices and relevant protein expression in muscle insulin signaling pathway were measured.Results Compared with model group, starfish saponins reduced hepatic lipids content and improved liver functions.In addition, it effectively ameliorated insulin resistance by improving insulin signaling pathway and improved glucose uptake in muscle.Conclusion The amelioration effect of starfish saponins on impaired insulin signaling pathway in muscle is observed in orotic acid-induced NAFLD rats.

Objective Comparing biological characteristics and the roles in repairing of intestinal irradiation injury of bone marrow derived Flk-1+ MSCs and small intestinal derived SP cells.Methods Phenotypes of the two cell population were determined by flow cytometery.Flk-1+ MSCs and intestinal SP cells were infused into irradiated mice,distribution and differentiation of these cells were determined.Histopathological change and fibrosis were evaluated.Results The phenotypes of Flk-1+ MSCs and intestinal SP cells were quite different.Both Flk-1+ MSCs and intestinal SP cells could home to injury tissue rapidly,participate intestinal epithelial repair,and alleviate fibrosis and collagen deposition after irradiation.SP cells mostly engrafted into intestinal epithelium,while Flk-1+ MSCs partly engrafted into interstitial region as well as epithelium.Conclusion Flk-1+ MSCs and intestinal SP cells may alleviate symptoms effectively,though their mechanisms are disparite.

In November 1981,an ancient female cadaver of Qidan nationality in wulanchatu League of InnerMongolia was excavated.This cadaver was estimated approximately 25 year of age.She has been buriedfor about 900 years.The cadaver was a mummified corpse,and preserved in a comparatively intact state. The hair was intact and dark brown in colour.All viseral organs were dreg-like and dark brown incolour.The individual organ could not be identified from its exernal appearance.Only lungs werepreserved,adhering to the back of the thoracic cavity and looked like dry leaves.The peritonem wasdry and translucent and contained a few blood vessels.The muscles were also dry and dark brown or brownishgray in colour.The alveoli and the parenchma of the lung as well as bacterial spores were identified.The histologicalstructure of tissues from the heart region looked like the cross section of cardiac fiber.Collagenous fiberswere seen.Other tissues were mostly autolyzed.The cadaver were group B.According to results of toxic analysis,larger amount of arsenic was demonstratedin tissues from the stomach region.So it was deduced that the lady might die of an arsenical poisoning.Factors involving in the well preservation of this case are discussed.
