Objective:To explore the therapeutic effect of compound Kuijie Ankang Decoction on ulcerative colitis (UC) model mice by non targeted metabonomics; To explore its mechanism.Compound Kuijie Ankang.Methods:The mice were randomly divided into blank control group, model group, Kuijie Ankang Decoction group and sulfasalazine group, with 12 mice in each group. Except the blank control group, the other groups were given 1.5% DSS solution for free drinking to prepare UC model. After successful modeling, Kuijie Ankang Decoction group was intragastrically administered with compound Kuijie Ankang Decoction of 9.68 g/kg, sulfasalazine group was intragastrically administered with sulfasalazine capsule suspension of 320 mg/kg, model group and blank control group were intragastrically administered with equal volume of purified water, once a day, for 7 consecutive days. The body mass and disease activity index (DAI) score of mice were measured. ELISA was used to measure the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and interleukin-10 (IL-10) in the colon tissue of mice; the protein expressions of Claudin-1 and Zo-1 in colon tissue were detected by immunofluorescence method. HE staining was used to observe the pathological changes in the colon, and UHPLC-OE-MS technology was used to analyze the endogenous metabolite structure of mouse colon tissue, differential metabolites and related metabolic pathways were screened.Results:Compared with the model group, the colon length in Kuijie Ankang Decoction group and sulfasalazine group increased ( P<0.01), the DAI score decreased ( P<0.01), the levels of TNF-α, IL-1β and IL-6 in colon tissue decreased ( P<0.01), the level of IL-10 increased ( P<0.01), and the average optical density of Claudin-1 and Zo-1 protein increased ( P<0.01 or P<0.05). Metabolomics analysis identified 26 potential differential metabolites, including nicotinamide adenine dinucleotide, guanine, gamma aminobutyric acid, and thiamine, affecting 26 key metabolic pathways, including lysine biosynthesis, thiamine metabolism, cysteine and methionine metabolism. Conclusion:Kuaijie Ankang Decoction may improve metabolites such as Gamma aminobutyric acid and thiamine through metabolic pathways such as lysine biosynthesis to alleviate inflammatory reactions, thereby exerting therapeutic effects on ulcerative colitis in mice.

To explore the relationship between cancer awareness and the survival of the patients with non-small cell lung carcinoma (NSCLC).
 Methods: A total of 865 NSCLC patients were screened for the risk factors, including age, gender, address, tumor/lymph nodes/metastasis (TNM) stage, and cancer awareness. Survival of the patients was calculated by Kaplan-Meier method and Cox regression analysis.
 Results: After an average observation time of 304 d (ranging from 0 to 4 718 d), 62 of the 394 patients in the cancer awareness group survived, whereas 26 of the 471 patients in the cancer concealment group survived. Cancer-specific and all-cause survival was poorer in the cancer concealment group (P<0.001 for each, log-rank test). Cox multivariate regression analysis showed that cancer concealment displayed significantly lower cancer-specific survival [hazard ratio (HR)=1.534, 95% confidence interval (CI) 1.320 to 1.784, P<0.001] and all-cause survival (HR=1.558, 95% CI 1.346 to 1.803, P<0.001).
 Conclusion: Cancer concealment is associated with a poor survival of NSCLC patients, which may prohibit the patients from obtaining the real "right to survival".

OBJECTIVE: To investigate the expression pattern of adapter protein with a Src-homology 2 domain (SH2B1), the suppressor of cytokine signaling-3 (SOCS3), protein-tyrosine phosphatase 1B (PTP1B) and neturopetide Y (NPY) in obese and normal mice hypothalamus and its relation with serum leptin and insulin levels. METHODS: The obesity animal model was prepared with healthy C57/bl6 mice. Lee's index and Homeostasis model assessment-insulin resistance (HOMA-IR) were calculated. The mRNA levels of SH2B1, SOCS3, PTP1B and NPY were measured by fluorescent quantitation RT-PCR. The SH2B1 and NPY protein expressions were detected by Western blot. RESULTS: Compared with the normal mice of the same age, SH2B1 mRNA expression in the obese mice hypothalamus decreased. SOCS3 and PTP1B mRNA expression increased. Western blot showed that SH2B1 protein expression decreased, while NPY protein expression increased in the obese mice. Linear correlation analysis showed that the serum leptin and fasting insulin levels were negatively correlated with SH2B1mRNA expression and positively correlated with SOCS3 and PTP1B mRNA expression. CONCLUSION SH2B1, SOCS3, PTP1B and NPY are key factors for obesity development.

OBJECTIVE: To explore the protective effects of ischemic postconditioning on non-heart-beating donor (NHBD) in rat NHBD lung transplantation model. METHODS: Forty Sprague-Dawley rats were randomized into the ischemic postconditioning group (IPO group) and the control group (C group), 10 pairs in each group in which left lung orthotopic transplantations from NHBDs were done with " two-cuff-one-stent technique". In the C group, perfusion was resumed by declamping pulmonary artery immediately after transplantation, whereas in the IPO group, 5 cycles of 1-min reperfusion and 1-min reocclusion of pulmonary artery were applied as postcontioning before full recovery of perfusion. RESULTS: Compared with the C group, water content of donor lungs was lower and pathological changes were milder in the IPO group, meanwhile compliance, structure and function of donor lungs were better preserved. Furthermore, the expression of cell apoptosis and MDA content in donor lungs were lower in the IPO group, while SOD content was higher. CONCLUSION Ischemic postconditioning can reduce ischemic reperfusion injury of NHBD lung transplantation and preserve the structure and function of donor lungs. It can inhibit lipid peroxidation and cell apoptosis in NHBD lungs after transplantation.
