After half a century of self-innovation, the integrated traditional Chinese and Western medicine has witnessed the great progress in both clinical and basic research. However, the theoretical system of the integrative medicine does not break through the limitations of traditional Chinese medicine and Western medicine, which hinders its implication in experimental study and clinical work. In view of the current situation, to develop the integration of traditional Chinese and Western medicine further, efforts should be made in such aspects as educational system construction, talent personnel training, improving the level of clinical practice and corresponding basic research as well as the establishing the basic theoretical system.

And the smoking quality of the flue-cured tobacco leaves treated was much better than the control.

Objective To detect the levels of five trace elements in whole blood of patients with Keshan disease(KSD) and dilated cardiomyopathy(DCM) and explore their role in the pathogenesis of KSD.Methods One hundred and four patients with chronic KSD were selected from Keshan diseased areas in Shandong,Sichuan and Inner Mongolia.Thirty patients with DCM were selected from Qilu Hospital of Shandong University,Jinan Central Hospital,The First People's Hospital.Ninety-one healthy people from KSD endemic areas and 39 healthy people from Jinan were selected as endemic healthy controls and non-endemic healthy controls,respectively.Blood samples were collected to determinate the level of selenium (Se),copper (Cu),zinc (Zn),chromium (Cr) and manganese (Mn) with fluorescence method and atomic absorption spectrometry,according to the principle of informed consent.Results The level of Se,Zn and Cr of KSD group[(36.0 + 4.9)μg/L,(22.73 + 4.62)mg/L,(0.56 + 0.17)mg/L] was significantly lower than that of non-endemic healthy controls [(56.4 ± 6.8)lμg/L,(25.35 ± 4.44)mg/L,(0.71 ± 0.17)mg/L,all P ＜ 0.05],but the level of Cu of KSD group[(0.95 ± 0.24)mg/L] was significantly higher than that of non-endemic healthy controls[(0.73 ± 0.13) mg/L,all P ＜ 0.05].The level of Se and Cr of KSD was significantly lower than that of endemic healthy controls[(54.5 ± 5.4)μg/L,(0.87 ± 0.02)mg/L,P ＜ 0.05],and Cu was significantly higher than that of endemic healthy controls[(0.66 ± 0.02)mg/L,P ＜ 0.05].The level of Cu and Zn of KSD was significantly lower than that of DCM [(1.21 ± 0.23)mg/L,(27.09 ± 7.10)mg/L,all P ＜ 0.01].The level of Se and Cr of DCM group[(39.6 ± 3.5)μg/L,(0.58 ± 0.14)mg/L] was significantly lower than that of non-endemic healthy controls(all P ＜ 0.01),but Cu[(1.21 + 0.23)mg/L] was significantly increased (P ＜ 0.01).Compared with non-endemic healthy controls,the level of Se of endemic healthy control group was significantly decreased (P ＜ 0.01),while Cu was significantly increased (P ＜ 0.01).Se,Zn and Cr level of KSD decreased gradually following elevated heart function level,but the level of Cu gradually increased.Conclusions The metabolism of Se,Cr,Cu and Zn is unbalanced in KSD patients,whose Se level is still lower than that of people in non-endemic areas.The change of Se,Cr,Cu and Mn level between KSD and DCM is consistent.

OBJECTIVE: To investigate the effects of fenofibrate on the proliferation and apoptosis and endothelial nitric oxide synthase (eNOS) mRNA expression of cultured human umbilical vein endothelial cells (HUVECs) induced by lysophosphatidylcholine (LPC). METHODS: HUVECs were cultured in vitro. The study was designated to 5 groups according to fenofibrate concentration: control group, LPC group, LPC + low-concentration fenofibrate (10 micromol/L), LPC + middle-concentration fenofibrate (50 micromol/L), and LPC + high-concentration fenofibrate (100 micromol/L). The study was designated to 6 groups according to the intervention time: control group, LPC group, LPC + fenofibrate (50 micromol/L) 6 h, LPC + fenofibrate 12 h, LPC + fenofibrate 24 h, and LPC + fenofibrate 48 h. The proliferation and apoptosis of HUVECs were evaluated by MTT assay, flow cytometry and fluorescence microscopy, respectively. eNOS mRNA were assayed by real time-PCR. RESULTS: Compared with the control group, LPC could inhibit the proliferation and induce apoptosis, and downregulate eNOS mRNA expression and decrease NO production of HUVECs. Fenofibrate could increase the proliferation and decrease the apoptosis, and up-regulate eNOS mRNA expression and enhance NO production in HUVECs. CONCLUSION Fenofibrate could improve the proliferation and inhibit the apoptosis, and up-regulate eNOS mRNA expression of HUVECs induced by LPC, which may be responsible for fenofibrate to prevent and treat atherosclerosis.

OBJECTIVETo evaluate the association between serum level of leptin and leptin receptor gene (LEPR) polymorphism and patients with breast cancer.

METHODSLEPR G1n223Arg polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism in 94 patients with breast cancer and 128 healthy controls. The level of leptin were analyzed by enzyme linked immunosorbent assay.

RESULTSIn univariate regression analyses, we found serum level of leptin and LEPR Gin223Arg genotype polymorphism were significantly higrer than those of the controls (P < 0.05-0.001, respectively). Through multivariable analyses, we found that increased risk estimates for breast cancer were among those with leptin level (OR = 1.53, 95% CI: 1.13-2.07, P = 0.006), LEPR Gin223Arg genotype (OR = 4.87, 95%CI:1.30-18.22, P = 0.019), WHR (OR = 3.68, 95% CI: 1.34-10.11, P = 0.011).

CONCLUSIONResults from this study suggested that LEPR Gln233Agr polymorphism, the elevated WHR and serum level of leptin might be correlated with increased risk of breast cancer.

OBJECTIVETo study the cleavage activity of specific deoxyribozyme to hepatitis C virus in vitro.

METHODSThree deoxyribozymes were designed to cleave at sites 157, 168, 173 in HCV 5'-noncoding region with the active region of 5'-GGCTAGCTACAACGA-3' respectively. Plasmid pCMV/T7-NCRC -Delta Luc was completely linearized with restriction endonuclease Xba I. HCV RNA5'-NCRC was transcribed in vitro from the linearized products and radiolabelled with [alpha-32P] UTP. Under the conditions of 37 degrees C, pH7.5, Mg2+ 10 mmol/L, the three deoxyribozymes were mixed with substrate RNA individually for 120 minutes and then the reactions were terminated. The cleavaged products were separated with 8% denaturated polyacrylamide gel electrophoresis and displayed by autoradiography. DRz3 was mixed with the substrate RNA at different Mg2+ concentrations. The cleavage efficiency was analyzed with a gel document action analyzing systems.

RESULTSUnder the adopted conditions the three deoxyribozymes efficiently cleaved to the target RNA in vitro and the cleavage activity of DRz3 was increased with the increase of Mg2+ concentration.

CONCLUSIONThe designed deoxyribozymes can cleave 5'-NCR mRNA of HCV efficiently in vitro and it is dose-respondent to Mg2+ concentration.

BACKGROUND:Rapid and complete reperfusion has been widely adopted in the treatment of patients with acute myocardial infarction (AMI), but this process sometimes can cause severe reperfusion injury. This study aimed to investigate different patterns of post-conditioning in acute myocardial ischemia-reperfusion injury, and to detect the role of mitogen activated protein kinase (MAPK) during the injury. METHODS:Rats were randomly divided into five groups:sham group, reperfusion injury (R/I) group, gradually decreased reperfusion group (GDR group, 30/10-25/15-15/25-10/30 seconds of reperfusion/ischemia), equal reperfusion group (ER group, 20/20 seconds reperfusion/ischemia, 4 cycles), and gradually increased reperfusion group (GIR group, 10/30-15/25-25/15-30/10 seconds of reperfusion/ischemia). Acute myocardial infarction and ischemic post-conditioning models were established in the rats. Six hours after reperfusion, 3 rats from each group were sacrificed and myocardial tissues were taken to measure the expressions of phosphorylation of extracellular signal-regulated protein kinase (P-ERK), phosphorylated c-Jun N-terminal kinase (P-JNK), mitogen-activated protein kinase p38 (p38 MAPK), tumor necrosis factor-α (TNF-α), caspases-8 in the myocardial tissue, and cytochrome c in the cytosol using Western blot. Hemodynamics was measured at 24 hours after reperfusion, the blood was drawn for the determination of cardiac enzymes, and the heart tissue was collected for the measurement of apoptosis using TUNEL. One-way analysis of variance and the Q test were employed to determine differences in individual variables between the 5 groups. RESULTS:Three post-conditioning patterns were found to provide cardioprotection (P<0.05) compared with R/I without postconditioning. GIR provided the best cardioprotection effect, followed by ER and then GDR. Apoptotic index and serum marker levels were reduced more significantly in GIR than in ER (P<0.05). The enhanced cardioprotection provided by GIR was accompanied with significantly increased levels of P-ERK 1/2 (1.82±0.22 vs. 1.54±0.32,P<0.05), and lower levels of p-JNK, p38 MAPK, TNF-α, caspase-8, caspase-9 and cytochrome in the cytoplasm (P<0.05), compared with ER. The infarct size was smaller in the GIR group than in the ER group, but this difference was not significant (16.30％±5.22％ vs. 20.57％±6.32％,P<0.05). Allthe measured variables were improved more significantly in the GIR group than in the GDR group (P<0.05). CONCLUSION:Gradually increased reperfusion in post-conditioning could attenuate reperfusion injury more significantly than routine method, thereby the MAPK pathway plays an important role in this process.
