Objective To investigate the clinical effect of preoperative nutritional treatment and perioperative nutrition support for the patients with esophageal cancer.Methods According to the digital table,90 patients with esophageal cancer were divided into the control group(15 cases),preoperative nutrition group(25 cases),postoperation nutrition group(25 cases)and preoperative nutrition + postoperation nutrition group(25 cases).The postoperative quality of life and the complications were compared.Results Postoperative quality of life in the preoperative nutrition group,postoperation nutrition group and preoperative nutrition + postoperation nutrition group were all better than that in the control group(t =14.76,15.13,17.87,all P ＜ 0.05).The incidence rate of postoperative complications in patients received nutritional intervention significantly decreased than in the control group(x2 =9.17,12.13,19.18,all P ＜ 0.05).Conclusion The preoperative nutrition and postoperation nutrition can improve the postoperative quality of life and reduce the incidence rate of the complications.

Objective To investigate the effect of escharectomy on rats' pulmonary NF-?B activation and the expression of pulmonary proinflammatory cytokines in early stage of burn injury.Method Wistar rats were randomly divided into three groups:group A(control group),group B(postburn without escharectomy),group C(escharectomy at early stage of burn injury).Thermal-injuried rats underwent 35% TBSA full-thickness burns. Activation of pulmonary NF-?B at 12 hours and 24 hours postburn was tested by electrophoretic mobility shift assay (EMSA),and at the same time expressions of pulmonary TNF-?mRNA were measured by reverse transcription polymerase chain reaction(RT-PCR)and release of pulmonary TNF-?were assayed by enzyme-linked immunosorbent assay(ELISA).Results Compared with control group,activity of pulmonary NF-?B in group B was markedly increased,reached(19.56?1.36)?10~4 A at 12 hours and(15.23?1.94)?10~4 A at 24 hours,which was higher than that in group A[(4.36?0.38)?10~4 A,P

OBJECTIVE:To investigate off-indication use of oral chemical drugs medical orders by the standards of CFDA and FDA,and to compare the differences between the two standards,analyze reasons and rationality of drug use,so as to pro-vide reference for establishing off-indications use management system. METHODS:The oral chemical drugs medical orders of inpatients were analyzed statistically during Jan.-Jun. 2016. Off-label uses was judged according to the standards of CFDA and FDA. RESULTS:Totally 507 oral chemical drugs medical orders were collected,the percentage of off-indications use were in high level,being 58.58% and 55.82% respectively by the standards of CFDA and FDA. The incidence of off-indication use of quetiapine and aripiprazole by the CFDA standards were significantly higher than the results of FDA standards,with statistical significance(P<0.05). Magnesium valproate(54.03%),escitalopram oxalate(10.45%)and quetiapine(10.15%)occupied the top 3 places in the list of constituent ratio. Among off-indication medical orders,7 orders had no evidence-based medicine,ac-counting for 2.36% of total. CONCLUSIONS:Most off-indication medical orders of our hospital could provide the basis and lit-erature support,while there are still a few off-indication use with insufficient evidence. The corresponding management system of the hospital should be formulated to guarantee the medication safety of the patients and legitimate rights and interests of the doctors.

In-vitro assay methods were established to evaluate transactivation and binding activity of compounds on peroxisome proliferator-activated receptor y (PPARγ). Firstly, plasmids were constructed for transactivation assay of PPARγ response element (PPRE) triggered reporter gene expression, and for cell-based binding activity assay of the chimeric receptor, which was fused with PPARγ ligand binding domain (LBD) and yeast transcriptional activator Gal4. Secondly, by using PPARy competitive binding assay based on time resolved-fluorescence resonance energy transfer (TR-FRET), affinities of compounds and drugs to PPARγ were evaluated. In application of these above methods, the PPARγ activating potency and characteristics of different compounds were evaluated, and a novel benzeneselfonamide derivative, ZLJ01, was found to have comparable binding activity and affinity with the well-known PPARy agonist, but lack of PPRE mediated transactivation activity. In preliminary study on in-vitro hypoglycemic activity, ZLJ1 was found to promote insulin-stimulated glucose uptake by liver cells. Therefore, we believe that combining transactivation and binding activity as well as affinity evaluation, the system could be used to screen non-agonist PPARγ ligand as anovel PPARγ modulator

Our previous study revealed that spaceflight induced biological changes in human cervical carcinoma Caski cells. Here, we report that 48A9 cells, which were subcloned from Caski cells, experienced significant growth suppression and exhibited low tumorigenic ability after spaceflight. To further understand the potential mechanism at the transcriptional level, we compared gene expression between 48A9 cells and ground control Caski cells with suppression subtractive hybridization (SSH) and reverse Northern blotting methods, and analyzed the relative gene network and molecular functions with the Ingenuity Pathways Analysis (IPA) program. We found 5 genes, SUB1, SGEF, MALAT-1, MYL6, and MT-CO2, to be up-regulated and identified 3 new cDNAs, termed B4, B5, and C4, in 48A9 cells. In addition, we also identified the two most significant gene networks to indicate the function of these genes using the IPA program. To our knowledge, our results show for the first time that spaceflight can reduce the growth of tumor cells, and we also provide a new model for oncogenesis study.

OBJECTIVETo assess the feasibility and accuracy of CT coronary angiography (CTCA) combined with adenosine stress myocardial perfusion scintigraphy (MPS) for diagnosis of flow-limiting coronary stenosis.

METHODSA total of 105 patients with suspected or established coronary artery disease (CAD) underwent CTCA and MPS within 4 weeks before invasive coronary angiography. The accuracy of CTCA/MPS in the diagnosis of flow-limiting coronary stenosis was evaluated in comparison with the results of quantitative coronary angiography and MPS.

RESULTSThe sensitivity, specificity, positive predictive value and negative predictive value of CTCA/MPS as a combined approach for detection of flow-limiting coronary stenosis were all 100%. In 16% (9/55) of the patients, revascularization procedures were performed and no flow-limiting stenosis was found.

CONCLUSIONCombination of CTCA and MPS has an excellent accuracy for detecting flow-limiting coronary stenosis as compared with quantitative coronary angiography/MPI, and can be a useful gatekeeper for revascularization procedures.

BACKGROUNDHyalinizing trabecular tumor (HTT) is a rare thyroid neoplasm, which shares some histologic features with thyroid papillary carcinoma (TPC). Clinically, it is frequently misdiagnosed as papillary carcinoma, even for some experienced pathologists. The aim of this study was to investigate whether HTT is variant of TPC or HTT is an independent entity of thyroid neoplasm.

METHODSThe expression of CK19, galectin-3, HBME-1 and MIB-1 was detected by immunohistochemical staining in 12 cases of hyalinizing trabecular tumor and 20 cases of thyroid papillary carcinoma.

RESULTSTwo of the 12 HTT samples were positive or focally positive for CK19. Four of the 12 samples of HTT presented positive to galectin-3; 3 were stained strongly and the other one was focally positive. None of the 12 samples of HTT was positive for HBME-1. Five in 12 HTT samples were stained in nucleus for MIB-1. Almost all the 20 cases of thyroid papillary carcinoma were intensely stained for CK19, galectin-3 and HBME-1. Fifteen in 20 cases of thyroid papillary carcinoma showed nuclear staining for MIB-1.

CONCLUSIONSHTT is an independent thyroid neoplasm, not a variant of TPC. This study could help in the differential diagnosis of HTT from TPC. CK19, galectin-3 and HBME-1 are adequate to identify HTT and TPC, but MIB-1 does not play an important role in discrimination between HTT and TPC.
