Objective To explore the role of sCD44v6 in the diagnosis of colorectum cancer. Methods ELISA was used to detect the concentration of sCD44v6 of 81 patients after or before surgery.Results The level of sCD44v6 in the group of colorectum cancer was 200.5?31.1 ng/ml, which was higher than that of normal controls (45.6?9.5ng/ml) and that of patients with coloritis (48.3?7.6ng/ml). The concentration of sCD44v6 in the group of colorectum cancer with metastasis(280.1?26.9ng/ml) was higher than that of the group without metastasis(160.9?34.4ng/ml). The level of sCD44v6 was related to tumor burden.Conclusions The level of sCD44v6 is closely related to colorectal cancer and its metastasis. It would be useful in the diagnosis, prognosis, and forcasting of metastasis.

Objective:To investigate the effects of rosuvastatin and lfuvastatin on patients with acute coronary syndrome (ACS) combing impaired glucose tolerance (IGT).
Methods: A total of 215 consecutive ACS patients combing IGT treated in our hospital from 2009-05 to 2011-05 were studied. The patients were randomly divided into 2 groups, Rosuvastatin group, the patients received rosuvastatin10mg/day, n=108 and Fluvastatin group, the patients received fluvastatin 40mg/day, n=107. The total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) levels before and at 6, 12, 24 months after medication, fasting blood glucose (FBG), 2-hour postprandial glucose (2hPBG) and the number of new-onset of diabetes patients were compared between 2 groups.
Results: After treatment, the TC, LDL-C levels were decreased (6, 12, 24 months) and the HDL-C level (12, 24 months), 2hPBG (24 months) were increased in both groups. Compared with Fluvastatin group, Rosuvastatin group had decreased TC and LDL-C (6, 12, 24 months), and increased LDL-C (24 months). With 6, 12, 24 months treatment, the blood lipids reached the standard were more in Rosuvastatin group than those in Fluvastatin group as 35.3%vs 26.1%, 36.4% vs 22.0%, 43.1% vs 31.8% respectively, all P<0.05. With 12 and 24 months treatment, the new-onset diabetes patients in Rosuvastatin group were 11 and 18, in Fluvastatin group were 12 and 17. With 12, 24 months treatment, FBG, 2hPBG levels and the number of new-onset diabetes patients were similar between 2 groups, P>0.05.
Conclusion: Compared with lfuvastatin, the conventional dose of rosuvastatin could better reduce the blood lipids level in ACS patients combing IGT, the effects for preventing ACS patients from IGT to diabetes were similar for both drugs.

OBJECTIVETo investigate the role of miR-181c in glycolysis of cancer-associated fibroblasts (CAFs) and explore the mechanism.

METHODSHuman lung CAFs and normal fibroblasts (NFs), isolated from fresh human lung adenocarcinoma tissue specimens by primary culture of tissue explants, were transfected with a miR -181c mimics, a miR-181c inhibitor, a siRNA siRNA-HK2 or the vector HK2-vector via Lipofectamine(TM) 2000. Quantitative real-time PCR was used to analyze the changes in miR-125b expression in the transfected cells; hexokinase-2 (HK2) protein expression in the cells was detected using Western blotting, and the cellular glucose uptake was assessed with 2-NBDG. Lactate production in the cells was examined and expression of HK2 mRNA was detected with dual luciferase reporter gene assay.

RESULTSNo obvious difference was found in the cell morphology between CAFs and NFs. Compared with the NFs, the CAFs showed obviously increased glucose uptake, lactate production and HK2 protein expression with decreased expressions of the miR-181 family (P<0.05). Transfection with the miR-181 inhibito- rsignificantly increased glucose uptake, lactate production and HK2 protein expression in the NFs. In CAFs, transfection with the miR-181 mimics caused significantly lowered glucose uptake, lactate production and HK2 protein expression of. Knockdown of endogenous HK2 by siRNA abolished miR-181 mimics-mediated decrease of glucose uptake and lactate production in CAFs, while transfection with miR-181 mimics suppressed HK2 overexpression-induced enhancement of glucose uptake and lactate production in NFs.

CONCLUSIONTransfection with miR-181 mimics can suppress glycolysis in CAFs by inhibiting HK2 expression.

The hepatic arterial perfusion (HAP), hepatic portal perfusion (HPP) and hepatic perfusion index (HPI) of each group were calculated by maximum slope. T test was used for statistical analysis. Results:The BF of pancreas, spleen and left adrenal gland of ANC group was (139.89±34.28), (141.42±47.85) and (107.87±26.41) mL·min -1·(100 g) -1, respectively, the BF of pancreas, spleen and left adrenal gland of WON group was (130.00±44.83), (106.12±38.16) and (98.38±41.39) mL·min -1·(100 g) -1 respectively, and the BF of pancreas, spleen and left adrenal gland of WONI group was (127.91±35.86), (102.09±23.73) and (105.66±27.01) mL·min -1·(100 g) -1, respectively, which were all lower than those of control group ((161.22±31.60), (174.00±62.73) and (134.53±36.36) mL·min -1·(100 g) -1), and the differences were statistically significant ( t=2.440, 2.043, 2.943; 2.296, 3.796, 2.548; 2.448, 4.479, 2.154; all P<0.05). The BF of left kidney cortex of WONI group was lower than that of control group ((247.44±39.32) mL·min -1·(100 g) -1 vs. (294.80±39.13) mL·min -1·(100 g) -1), and the difference were statistically significant ( t=2.910, P<0.05). The HAP of ANC group, WON group and WONI group was (18.63±9.54), (19.10±7.47) and (19.51±6.26) mL·min -1·(100 g) -1, respectively, and the HPI was (25.01±15.51)%, (45.98±31.42)% and (35.92±24.95)%, respectively, which were all higher than those of control group ((12.18±5.14) mL·min -1·(100 g) -1 and (13.44±6.49)%), and the differences were statistically significant ( t=2.997, 3.088, 3.235; 3.503, 3.397, 2.517; all P<0.05) . The HPP of ANC group, WON group and WONI group was (72.37±21.76), (48.83±35.10) and (57.55±29.45) mL·min -1·(100 g) -1, respectively, which were all lower than that of control group ((86.43±17.98) mL·min -1·(100 g) -1), and the differences were statistically significant ( t=2.391, 3.331 and 3.226, all P<0.05). The HAP and HPI of APFC group were both higher than those of control group ((18.67±10.24) mL·min -1·(100 g) -1 vs. 12.18±5.14) mL·min -1·(100 g) -1 and (23.75±20.41)% vs. (13.44±6.49)%), and the differences were statistically significant ( t=2.572 and 2.108, both P<0.05) . Conclusions:AP complicated with ANC, WON and WONI can reduce the BF of pancreas, spleen and left adrenal gland, and WONI can induce the decrease of BF of left kindney cortex. AP complicated with ANC, WON and WONI can increase HAP and HPI, but decrease HPP. Furthermore, AP complicated with APFC can increase HAP.

Objective The study aimed to elucidate the evolution of the syndromes in Traditional Chinese Medicine(TCM)and TCM syndrome elements in different chronic stages of psoriasis vulgaris.Methods A database was constructed using electronic medical records collected from July 2019 to March 2024 from 1,049 patients with psoriasis vulgaris.The study used Sankey diagrams and network association graphs to analyze the evolution of TCM syndromes and their elements in patients at the different stages:initial diagnosis,progressive stage(Week 2-3),progressive stage(Week 4-5),skin lesion improvement stage(Week 6-7),and remission stage.The syndrome elements network was constructed using community detection algorithms,and the association rules between local skin lesion syndrome differentiation and overall syndrome differentiation were displayed using heatmaps.Results(ⅰ)Initial diagnosis.In the syndrome differentiation of local skin lesions,blood heat syndrome was the most common(79.79％);among the disease location of TCM syndrome elements(called"disease location"),liver was the most prevalent(35.62％);and among the pathological factors of TCM syndrome elements(called"pathological factors"),fire(heat)was the most common(75.48％).(ⅱ)Active stage(Week 2-3).In the syndrome differentiation of local skin lesions,blood heat syndrome remained the most prevalent(73.13％);among the disease location,liver was still the most prevalent(31.71％);and among the pathological factors,fire(heat)continued to be the most common(82.11％),while dampness(22.26％)and qi stagnation(8.39％)began to increase.(ⅲ)Active stage(Week 4-5).The syndrome differentiation of local skin lesions was dominated by blood heat syndrome(45.91％)and blood dryness syndrome(37.19％);among disease location,the interior was the most prevalent(15.25％);and among the pathological factors,fire(heat)remained the most common(50.66％),with an increase in yin deficiency(34.26％).(ⅳ)Skin lesion improvement stage(Week 6-7).In the syndrome differentiation of local skin lesions,both blood dryness syndrome(49.44％)and blood stasis syndrome(33.33％)increased;among the disease location,meridians increased most significantly and became the most prevalent(13.44％);and among the pathological factors,blood stasis increased most significantly and became the most prevalent(28.20％).(ⅴ)Remission stage.In the syndrome differentiation of local skin lesions,blood stasis syndrome became the primary(55.69％),while the percentage of blood dryness syndrome decreased(21.16％);meridians(25.71％)and blood stasis(62.34％)remained the most predominant syndrome elements related to disease location or pathological factors.Conclusion The overall pattern of TCM syndromes in psoriasis vulgaris evolved from excess to deficiency.From the initial diagnosis to the active phase(Week 2-3),heat syndrome dominated;during the active phase(Week 4-5),heat syndrome coexisted with damp syndrome or yin deficiency syndrome;changes in the syndrome element network were the most significant during the lesion improvement phase,with blood stasis gradually increasing and peaking during the remission phase.Blood stasis,dampness,and qi stagnation were pervasive throughout psoriasis vulgaris;qi stagnation and blood stasis may be the main elements causing further deterioration and prolonged course of the disease during the active phase in patients.

AlM: To explore the effects of irisin on house dust mite (HDM)-induced inflammation and apoptosis in human airway epithelial cells. METHODS: The human bronchial epithelial cell (16HBE) were cultured with in RPMI1640 culture medium with 10% of fetal bovine serum. After cells reached 85% confluence, the medium was replaced with serum-free culture medium for 12 h. Then the 16HBE cells were treated with various concentrations of HDM (0, 400, 800, 12 00 U/mL) for 24 h. Reactive oxygen species assay kit was used to detected the intracellular ROS generation. And qPCR was used to measure the interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α) mRNA expression of the HDM-induced 16HBE cell. The cells were pre-treated with or without irisin for 2 h before exposure to various concentration of HDM for 24 h. Then reactive oxygen species assay kit was used to detected the intracellular ROS generation. The IL-6, TNF-α mRNA expression of 16HBE cell were measured by qPCR. Meanwhile, the phosphorylated and total P65 NF-κB and JNK proteins were detected by western blot. The pro-apoptosis protein cleaved-caspase3BAX and the anti-apoptosis protein were also detected by western blot. RESULTS: The quantitative assay showed that intracellular ROS in different concentrations of HDM stimulus group were obviously higher than NC group (P < 0.05). And RT-PCR analysis showed a higher expression level of pro-inflammatory cytokine TNF-α and IL-6 mRNA in different concentrations of HDM than in NC group (P < 0.05). Compared with the HDM group, Irisin significantly decreased the level of intracellular ROS of the 16HBE cells (P < 0.05). The released of the pro-inflammatory cytokine TNF-α and IL-6 mRNA was also decreased in irisin treated 16HBE cells (P < 0.05). And compared with control group, BCL-XL anti-apoptosis protein level was decreased and BAX and c-caspase3 pro-apoptosis protein levels were increased in HDM group (P < 0.05), irisin intervention significantly increased the level of BCL-XL and decreased the levels of BAX and cleaved-caspase 3 (P < 0.05). Compared the control group, phosphorylated P65 NF-κB and JNK protein levels were significantly increased after HDM stimulated (P < 0.05), and irisin intervention decreased the protein levels of phosphorylated P65 NF-κB and JNK (P < 0.05). CONCLUSlON: Irisin can effectively improve the inflammation and apoptosis of HDM-induced 16HBE cells, and this protective effect may be related to its inhibition of NF-κB and JNK MAPK signaling pathways. Irisin may be a potential drug for treating lung inflammation.
