The main methods to treat locally advanced non-small cell lung cancer are radiotherapy and chemotherapy. The combination of radiotherapy and chemotherapy includes sequential chemoradiotherapy and concurrent chemoradiotherapy. The effectiveness of concurrent chemoradiotherapy is superior to that of sequential chemoradiotherapy, but the toxicity of concurrent chemoradiotherapy increases as well. Continuing to explore new ways which can improve the effectiveness and reduce the toxicity is the current and future direction. [Key words] Carcinoma, non-small cell lung; Radiotherapy; Drug therapy

Objective To observe the effect of meridian-thumbing therapy on flexion deformity on knees of children with cerebral palsy(CP).Methods The therapy of thumbing the points from Chengfu to Chengshan of the meridian of Foot Taiyang Bladder was used for 40 CP children with flexion deformity on knees.Results After three months treatment,the positive flexion of knee joint in 40 children improved significantly than before(P<0.001).Conclusion The therapy of meridian-thumbing has obvious effect on flexion deformity on knees of CP children.

OBJECTIVE To investigate Mycoplasma pneumoniae load index(MPLI)usefulness in the diagnosis of Mycoplasma pneumoniae(MP) infection in children.METHODS 110 throat swabs were collected with paired sera from the department of pediatry in our hospital from March to July 2008.The former fluorescence quantitative(FQ)-PCR assay was used to analyze throat swabs,microparticle agglutination assay(MAG) and MP-IgM assay for the sera.MP-IgM positive once or twice was used as a gold standard for MP infection,on which sensitivity(SEN),specificity(SPE),positive predictive value(+PV),negative predictive value(-PV) and ROC were calculated.RESULTS According to the gold standard,the values of SEN,SPE,+PV,-PV were 73.1-100.0%for a single MP-IgM,26.9-94.0% for a single MAG,46.2-94.0% for double MAG,26.9-95.2% for FQ-PCR alone and 26.9-98.8% for MPLI,respectively.CONCLUSIONS MAG shows limit in its clinical usage for the detection of MP antibodies.MPLI can diagnose acute MP infection earlier than MP-IgM.

It is a request of social development for medical service to provide patients with high-quality and humanistic medical care.The medical science reform should be strengthened in order to disassociate medical care and medicine marketing.Medical service reform is to be furthered and medical curriculum be properly set up.The medical specialities,public subjects and humanistic care curricula should be compatible with each other,in order to coordinate with the development of modern medical skills and the cultivation of humanistic spirit,and cultivate medical talents with both exquisite medical skills and noble medical professionalism.

Alteration of intracellular free calcium during hypoxia was studied in cul-tured porcine pulmonary arterial endothelial cells. Intracellular free calcium was measuredwith the fluorescent prob, Fura-2/AM. It was found that hypoxia induced by bubbling N_2 to cells suspension increased intracellular free calcium of endothelial cells by 81?21%(n=8, P

Objective To explore the clinical , EMG and genetic characteristics of children with hereditary neuropathy with liability to pressure palsies phenotype (HNPP).Methods One case of HNPP diagnosed by gene were reported, and combined with the literature , the clinical, electromyography and genetic characteristics were summarized.Results Female patient, 11 years and 8 months, left foot could not be dorsal flexion and numbness appeared after the movement in 10 d before admission ,EMG showed multiple peripheral nerve injury .Patient's father and uncle were very similar to the history .Genetic examination showed 1363.2 kb heterozygous deletion on the chr17:14095421 -15458636, and the diagnosis was HNPP .Conclusions When limb weakness happened in children after slight stretch or compression , perform EMG examination as early as possible .Children with extensive peripheral nerve damage , limited limb paralysis , and a similar family history , should pay attention to HNPP , and gene examination should be given .

Objective To investigate the effects of preconditioning with emulsified isoflurane(eISO)on inflammatory response to myocardial ischemia-reperfusion(I/R)injury in rats.Methods Forty SD rats of both sexes weighing 250-280 g were randomly allocated into 4 groups(n =10 each):groupⅠ sham operation(S);group Ⅱ myocardial I/R + normal saline(NS); group Ⅲ I/R + eISO and group Ⅳ I/R + 30％ intralipid(Ⅱ.)(vehicle for eISO).Myocardial ischemia was induced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 180 min reperfusion.NS,30％ intralipid and elSO 2 ml/kg were infused iv over 30 min at 30 min before myocardial ischemia in groups Ⅱ,Ⅲ and Ⅳ respectively.The animals were killed at the end of 180 min repeffusion.Their hearts were removed for determination of infarct size and myocardial NF-κB p65 and ICAM-1 expression(by immuno-histochemistry)and plasma concentration of TNF-t(by radioimmunoassay).Results Myocardial I/R induced myocardial infarct and significantly increased plasina TNF-a concentration and myocardial ICAM-1 and NF-κB p65 expression in gro up Ⅱ,Ⅲ and Ⅳ as compared with'sham operation group (Ⅰ).Plasma TNF-a concentration and myocardial ICAM-1 and NF-kB p65 expression were significantly lower in group Ⅲ(eISO)than in group Ⅱ and Ⅳ.Conclusion Down-regulation of myocardial NF-kB and ICAM-1 expression and inhihition of inflammatoy response are involved in the mechanism by which preconditioning with iv elso protects against myocardial I/R injury.

Cardiovascular disease is a frequently-occurring disease of human society, each year many patients in need of vascular graft surgery. The emergency and application of tissue engineered blood vessels, in particular the application of nanomaterials, will hopefully solve the problem of vascular sources. Here this article reviews the research contents and performance evaluation of tissue engineered blood vessels.

Colon cancer stem cells(Co-CSCs)are a small fraction of subgroup cells,which show the capabilities of self-renewal,proliferation and differentiation in colon cancer.Co-CSCs are tumorgenic,and they play an important role in the genesis development and metastasis of tumor.These studies of Co-CSCs may help developing effective targets and novel strategies for clinical tumor therapy.

The incidence of Crohn disease has gradually increased in recent years. The diagnosis and treatment of Crohn disease has gained more and more attention from clinicians. This article is to propose solutions to problems in the diagnosis and treatment of Crohn disease, based on evidence from clinical trials, including the diagnosis, differential diagnosis, management of steroid-refractory disease and anal fistula, and timing of surgery.
