Objective To evaluate the prognostic value of fluorodeoxyglucose (FDG) standardized uptake value (SUV) of positron emission tomography (PET) before radiotherapy in non-small cell lung cancer (NSCLC) treated with three-dimensional conformal radiation therapy (3DCRT). Methods Seventy-three patients with stage Ⅲ NSCLC underwent PET to calculate SUV within 2 weeks before 3DCRT. The a-nalysis was carried out after the irradiation of 60 -66 Gy. The possible prognostic factors were assessed by Cox proportional hazards model. Results The mean SUV for squamous cell carcinoma, adenocarcinoma and others were 16.94, 14.40 and 6.33, respectively (F = 0. 51, P = 0. 604). The mean SUV for tumor volume less than and more than 50 cm~3 was 13.81 and 20.18 (F = 7.54, P = 0. 008). In the univariate analysis, a cutoff SUV of 17 and chemotherapy were correlated with the prognosis. In the multivariate analysis, SUV was the only independent prognostic factor (relative risk = 2.61). Conclusions SUV is a prognostic factor in patients with NSCLC treated by 3DCRT, which deserves further studies.

Objective To study changes and effects of transforming growth factor-?1(TGF- ?1) and its receptorIII (TGF-?1 R III) in children with idiopathic thrombocytopenic purpura (ITP). Methods Bone marrow were respectively collected from 28 children with acute idiopathic thrombocytopenic pupura(AITP),16 children with chronic idiopathic thrombocytopenic purpura(CITP) and 20 comparably normal children; Percoll density gradient and immunomagnetic beads methods were used to purify megakaryocytes from bone marrow; ABC- ELISA was used to detect TGF - ?1 in bone marrow; in situ hybridization was used to detect TGF-?1 RIIImR-NA expression on megakaryocytes.Results In AITP and CITP group, the levels of TGF-?1 and TGF-?1 RIIImRNA were significant higher than those in control group(P

Objective To investigate the effect of 17β-estradiol on insulin resistance and the expression of insulin receptor-α in skeletal muscle of ovariectomized rats with insulin resistance induced by high fructose.Methods Forty-eight mature female Sprague-Dawley (SD) rats were randomly divided into four groups: the normal control group (NC, n= 12) rats were fed with the normal diet for 8 weeks; the model group (M, n= 12)rats were ovariectomized and fed with the high fructose diet for 8 weeks, meanwhile the physiological-dose of 17βestradiol (30 μg · kg-1 · d-1 ) was injected subcutaneously every day; the vehicle control group (VC, n= 12) rats were ovariectomized and fed with the high fructose diet for eight weeks, meanwhile equivalent alcohol was injected subcutaneously every day. Systolic blood pressure (SBP), fasting blood sugar (FBS), and fasting serum insulin (FSI) were measured and insulin sensitivity index (ISI) was calculated. The expressions of mRNA and protein of insulin receptor-α in quadriceps femoris were measured by RT-PCR and Western-blot. Results Compared with the normal control group, SBP (P<0.05), FBS (P<0.05) and FSI (P<0.01) were increased significantly while ISI was decreased significantly (P < 0. 05) in the model group. The expressions of mRNA and protein of insulin receptor-α and phosphorylated Akt were decreased significantly in quadriceps femoris in the model group (P<0.05), compared with the normal control group. However, these effects were reversed by 17β-estradiol in the 17βestradiol replacement group. Conclusions 17β-Estradiol inhibits insulin resistance, and up-regulates the expression of insulin receptor-α and the level of phosphorylated Akt in ovariectomized rats with insulin resistance induced by high fructose diet.

OBJECTIVETo explore the perioperative cardiovascular dysfunction and its relevance to age in patients with silent coronary heart disease (or silent myocardial ischemia), and explore the clinical treatment and recovery of perioperative arrhythmias.

METHODSOne hundred and eighty cases were selected from selective surgery patients with silent myocardial ischemia (SMI). Among the cases, 130 patients older than 51 years old were divided into 51 - 60 year-old group, 61- 70 year-old group and 71 - 80 year-old group. Control group was set up by other 50 patients younger than 51 years old. Electrocardiogram data of 24 h before the operation, 24 h after the operation and 48 h after the operation were continuously monitored by dynamic electrocardiogram (DCG). The electrocardiogram data of ST shifting, arrhythmia incidences of different type and at different time were analyzed by professional doctors. At the same time, the treatment and recovery of perioperative arrhythmia were recorded.

RESULTSAs the age increase, the magnitude and duration of ST shifting appeared upward trend compared to the control group (P < 0.05, P < 0.01). The incidence of ST elevation in 71 - 80 year-old group was higher than the control group (P < 0.05). The ST depression duration in 61 - 70 and 71 - 80 year-old group and ST elevation magnitude in 71 - 80 year-old group were higher than 51 - 60 year-old group (P < 0.05). Compared to the control group, the incidence of accelerated idioventricular rhythm (AIR) in 61 - 70 year-old group and the incidence of sinus bradycardia (SB), ventricular premature beat (VPB), ventricular tachycardia (VT) in 71 - 80 year-old group were higher (P < 0.05, P < 0.01). Compared to the 51 - 60 year-old group, the incidence of atrial fibrillation (AF) in 61 - 70 year-old group and the incidence of VP, VT, AF in 71 - 80 year-old group were higher (P < 0.05, P < 0.01). The arrhythmia incidences in 24 h after operation were higher than 48 h after operation and 24 h before operation (P < 0.01). As the age increase, the recovery incidence by removing inducement was decreased, but the recovery incidences by drug and electric-shock treatment were increased (P < 0.05).

CONCLUSIONOld SMI patients have high levels of perioperative myocardial ischemia and arrhythmia, and 24 h after operation is the period of high incidence.
