Objective To observe the clinical efficacy of electroacupuncture in treating functional constipation. Method Sixty patients with functional constipation were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by electroacupuncture, while the control group was by sham-electroacupuncture. The Clinic Constipation Score (CCS), therapeutic efficacy index, plasma NOS, and plasma 5-HT were observed before and after intervention.Result The CCS was changed significantly after intervention in both groups (P<0.05). After intervention, there was a significant difference in comparing the CCS between the two groups (P<0.05). The total effective rate was 93.3% in the treatment group versus 66.7% in the control group, and the difference was statistically significant (P<0.05). The NOS and 5-HT contents were changed significantly after intervention in both groups (P<0.05). After intervention, there were significant differences in comparing the NOS and 5-HT contents between the two groups (P<0.05).Conclusion Electroacupuncture is an effective approach in treating functional constipation, and it can improve NOS and 5-HT contents in gastrointestinal tract.

The results show that the overall influence of medical core journals assume trend of escalation during the Tenth Five-year, but the growth rate is relatively slowed down. There arc extremely differences in influence levels of medical journals between in China and international, but the overall superiority of medical journals as well as the increasing impact could be continued.

Objective To determine the effect of cetuximab(C225)on the radioresistant human esophageal squamous carcinoma eell line KYSE-150R.Methods A radioresistant human esophageal squamous carcinoma cell line KYSE-150R was established by fractionated irradiation.Morphological changes from KYSE-150 to KYSE-150R were observed by phase-contrast microscopy.Karyotype analysis was performed by G-banding.The radiosensitivities were analyzed by colony formation assays.Results The population doubling time of KYSE-150 and KYSE-150R were(23.6±0.2)h and(25.9±0.6)h (t=6.6,P<0.01),respectively.The chromosome number of KYSE-150R was increased and chromosome aberrations were observed from(69.3±1.9)h to(73.7±1.2)h(t=-8.83,P<0.01).The SF2,D0,Dq and N values of KYSE-150R were all higher than those of KYSE-150.After 5μg/ml of C225 added,the SF2,D0,Dq and N values were significantly decreased as compared to the control.After C225 treatment,the G0/G1 and G2/M phase cells were increased,while S-phase cells decreased(t=-4.478-4.308,P<0.05).Conclusion Cetuximab can enhance the radiosensitivity of radioresistant human esophageal squamous carcinoma cell line KYSE-150R.

Objective · To investigate the effect of metformin on insulin resistance (IR)-related metabolic parameters in olanzapine-bearing rats.Methods · Thirty female SD rats were randomly divided into metformin intervention group, olanzapine group and control group. During the first 6 weeks,5 mg /(kg·d) olanzapine was given to the two test groups . The control group was given the same amount of saline. From the 7th week, the intervention group began to combine with metformin 500 mg / (kg·d), while the olanzapine group combined with the same amount of saline, continuing for 4 weeks.At the end of 6th week and 10th week, intraperitoneal glucose tolerance and homeostasis model assessment IR index were assessed. Results · The area under the glucose tolerance curve (P=0.040) and the IR index (P=0.000) were significantly higher for the intervention group and the olanzapine group than the control group at the end of 6th week. At the 10th weekend, the glucose tolerance (P=0.015) and IR index in the intervention group were significantly lower than those in the olanzapine group (P=0.001). Conclusion · Metformin may rectify the impaired glucose tolerance and improve IR induced by olanzapine partly.

The effects of fenofibrate on plasminogen activator inhibitor-1 (PAI-1) expression in human umbilical endothelial cell-derived transformed cell line--ECV 304 cells were investigated. ECV 304 cells were incubated with different concentrations of fenofibrate (0, 10, 50, 100 micromol/L) for 24 h. PAI-1 mRNA and protein was detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot respectively. PAI-1 antigenic content of endothelial cells was measured by using ELISA. Fenofibrate could inhibit the PAI-1 mRNA and protein expression and reduce PAI-1 antigenic content dependently. After treatment with fenofibrate (10 micromol/L), the expression levels of PAI-1 mRNA and protein were 0.65 +/- 0.05 and 0.96 +/- 0.11 respectively, significantly lower than in the control group (0.78 +/- 0.03 and 1.21 +/- 0.15, respectively, P<0.05). PAI-1 antigenic contents (24.52 +/- 8.39) in ECV304 cells treated with 10 micromol/L fenofibrate were significantly lower than those in the control group (6.98 +/- 5.12, P<0.05). It was concluded that fenofibrate inhibited the expression of PAI-1 mRNA in ECV304 cells, and reduce the protein expression and the antigenic content of PAI-1, suggesting that fenofibrate may have an antiatherosclerotic effect on endothelial cells by PAI-1 pathway.

This study examined the association of a common polymorphic allele (25G) of the low-density lipoprotein receptor-related protein1 (LRP1) gene with myocardial infarction (MI). The genotypes of LRP1 25CG (rs35282763) were determined in 347 MI patients and 347 age- and sex-frequency-matched controls from an unrelated Chinese Han population. Factor VIII (FVIII) levels were measured in the MI patients and controls by chromogenic assay and enzyme-linked immunosorbent assay (ELISA). The results showed that LRP1 25CG (rs35282763) genotype distribution did not differ significantly between patients (n=206 for 25CC, n=122 for 25CG) and controls (n=191 for 25CC, n=126 for 25CG; P>0.05). The 25G allele was not associated with a reduced risk of MI (P>0.05). Further stratifications for age, sex, and other cardiovascular risk factors did not affect the negative findings. It was concluded that the presence of the G allele at the 25CG (rs35282763) polymorphism of the LRP1 is not associated with a reduced risk of MI, and genotyping for LRP1 25CG (rs35282763) polymorphism is not useful in assessing the individual risk of MI.

Objective To observe the changes of coagulation function in patients with acute lowerlimb deep venous thrombosis(DVT)and evaluate the risk factors for DVT. Methods Plasma APTT.PT,TT,D-dimer and fibrinogen(Fbg)were detected by an automated coagulation analyzer in 62 acute lower-limb DVT patients and 70 controls:Retrospective studies on the clinical data of all patients were done by binary logistic regression analysis.Results (1)In DVT group,plasma APTT,PT and TT,the levels of D-dimer and fibrinogen.and D-dimer/fibrinogen ratio(D/F ratio)were higher when compared with control group(au P＜0.01);(2)There were positive correlations between D-dimer and fibrinogen both in DVT and control groups(r=0.475,P＜0.01;r=0.564,P＜0.01,respectively);(3)Logistic analysis indicated that acute lower-limb DVT was associated with the presence of hypertension and increased plasma level of fibrinogen(OR=24.99,P＜0.01: OR=4.346.P＜0.01,respectively).Conclusions Hypertension and elevated plasma level of fibrinogen are independent risk factors for acute lower-limb DVT.
