Muscle recently has been identified as a good source of adult stem cells that can differentiate into cells of different lineages.Researchers have identified two types of stem cells in skeletal muscle.Further research is necessary to delineate the relationship between different populations of musclederived stem cells(MDSCs)and between MDSCs and other adult stem cells.The methods used to isolate these cells appear to influence the stem cell characteristics.As these efforts continue,the potential for MDSCsbased therapy for other musculoskeletal injuries,as well as for cardiac and smooth muscle injuries,is currently being explored.The behavior,biocharacteristic,isolation,differentiation and the probability of application to regenerate lost or diseased tissue of MDSCs were summarized.

Objective To explore the clinical effects of aortic valvuloplasty in treatment of ventricular septal defect(VSD)with moderate or severe aortic valve insufficiency(AI)in children.Methods Thirteen children less than 14 years old underwent open heart surgery as well as aortic valvuloplasty for VSD with moderate or severe AI.There were 9 cases of subpulmonary VSD,perimenbranous VSD in 4 cases.AI was mo-derate in 4 cases,severe in 9 cases.Results There was no hospital death.Post-operative echocardiogram and X-ray revealed that both cardiothoracic ratio and left ventricular end diastolic diameter decreased markedly(P

A HPLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to establish a determination method for drug concentrations of costunolide (Co) and dehydrocostuslactone (De) in blood samples in the positive ion mode, with diazepam as the internal standard substance, in order to study the pharmacokinetic process of sesquiterpene lactones costunolide and dehydrocostuslactone after the oral administration of Weichang'an pills, and provide an theoretical basis for further studies on the substance basis for the anti-diarrhea effect of Weichang'an pills. In the blood samples, Co and De showed a good linearity within concentration ranges 0.700 0-769.7, 2.510-956.0 μg x L(-1), respectively. The results of precision, stability and recovery experiences proved the stability and reliability of the plasma concentration determination method. After the oral administration, the concentrations of Co and De in plasma increased with the increase in dose, with T(max) between 10.65-12.98 h, indicating a long time to reach peak plasma concentrations; C(max) of costunolide and dehydrocostuslactone ranged between 3.750-5.450,15.34-44.52 μg x L(-1), respectively. The in vivo adsorption of Co and De conformed to the one-compartment model, with a longer time to attain the peak plasma concentrations. These results provided an experimental basis for revealing the active substance basis and clinical medication of Weichang'an pills.

Objective To study the efficacy and mechanism of compound Tripterygium hypoglaucum Hutch (THH) on photoallergic contact dermatitis in mice. Methods The photoallergic animal model of BALB/c mice was established by using photosensitizer chlorpromazine and UVA irradiation. The therepeutic efficacy was determined by measuring the thickness and the weight of the swelling ear and the number of infiltrated mononuclear cells in the ear tissue. Immunohistochemical technique was used to detect the ICAM-1 expression on keratinocytes, fibroblasts and vascular endothelial cells. The serum level of INF-? was measured by ELISA. The tested animals were divided into 3 groups: compound THH, THH alone and normal saline. Results The difference of the thickness of left ear before and after challenge, the differences of the thickness and the weight of ear tissue, the difference of the number of infiltrated mononuclear cells of left and right ear after challenge were significantly less in the compound THH group than those in the THH alone group (P

Objective To explore the effect of social medical treatment in improving the quality of life for patients with nasopharyngeal carcinoma.Methods 32 patients with nasopharyngeal carcinoma were mentioned with social medical treatment (including psychological treatment,family visit,family tend,social healing service,etc).The result was measured by using the SQOL-NPC.and the different stages of the results were compared.Results All the patients were tracked in 2 years.All the scores were mark down in a table.Conclusion After analyzing the results,it was found that social medical treatment played an important role in improving the quality of life for patients with nasopharyngeal carcinoma.

Objective Despite regular treatment,antineutrophil eytoplasmie antibodies(ANCA)asso- ciated systemic vasculitis(AASV),in which the role of Fc?Rs has been established,are still associated with significant long-term mortality and remain an important cause of end-stage renal failure.ANCA plays an im- portant role in the pathogenisis of primary systemic small vessel vasculitis(PSV)by their potential to activate neutrophils.Because the interaction between ANCA and its receptors on the Fc portion of immunoglobulins (Fc?R)on neutrophils is essential in the activation process,we investigate the inhibitory,effect of tg19320 on ANCA induced activation of neutrophils,which is a tetrameric tripeptide that interferes with IgG/Fe?Rs in- teraction.Methods We prepared tg19320 by solid-phase peptide syntbesis.The binding between tg19320 and human IgG was assessed by enzyme-linked immunosorbent assay.The biological activity of tg19320 to intefere with FcF?receptor recognition was identified by rosette formation assay.ANCA IgG was prepared from the sera of active Wegener's granulomatosis(WG)and microscopic polyangiitis(MPA)patients.Neu- trophils isolated from the blood of healthy volunteers were primed with TNF-?(2 ng/ml)and then incubated with ANCA IgG(200?g/ml),or pretreated with tg19320(2.5 mg/ml)and then added with ANCA IgG.Su- peroxide burst of neutrophils was determined by Ferri-cytochrome reduction assay.Results We found that tg19320 bound tightly to human IgG in a dose dependent manner and the inhibition of the rosette formation between SRBC-IgG and U937 cells was statistically significant(20.3% vs 53.2%,P

Objective To evaluate the using of either 225 or 150 microgrammes of mifepristone combined with misoprostol for termination of second-trimester gestation(16~24 weeks).Methods 180 women requesting voluntary induced abortion during gestation 16~24 weeks were randomised to three groups,group 1:oral mifepris- tone 225rag,group 2:oral mifepristone 150mg,and group 3:injected 100rag rivanot by amniocentestis.The total suc- cess rate,once success rate,the interval of having-medicine to uterine-constraction,the volume of bleeding within 2 hours after labour and cervical laceration rate were observed.Results The once success rate of induced labour in group 1 was higher than that in group 2 and group 3(P
