Objective To evaluate the association between parameters of heart rate turbulence (HRT) and the severity of the coronary arteries disease. Methods 60 patients with unstable angina pectoris (UAP) who under-went angiographic examination and 40 healthy controls were chosen. HRT including turbulence onset (TO), turbu-lence slope (TS) and turbulence dynamicity (TD) were determined by 24 h ambulatory electrocardiogram(Hoher) in all the patients. The value of above indices were compared between UAP group and control group,and between subgroups of UAP. The correlation of HRT with the severity of coronary arteries diseases was analyzed. Results The levels of TO and TD in patients with UAP were significantly higher than those in controls [(1.18±0.88) % vs lower TS (P<0.05) and higher TD (P<0.05 ) than those in patients with coronary single vessel lesion. The same -0.296, P<0.05 ) and coronary artery stenosis score (r=-0.372, P<0.05 ) ; TD was positively correlated with number of abnormal coronary artery (r=0.353, P<0.01 ) and coronary artery stenosis score (r=0.510, P < 0.05). Conclusion . HRT is impaired in patients with UAP,especially the changes of TS and TD is signflcant,and is correlated with the severity of coronary arteries disease. TD is not influenced by premature ventricualr contractionheart rate so the combinatoin of TD and TS might be used as objective index in predicting the severity of the coronary arteries disease.

Objective: To investigate the survival and individualized therapy of metastatic colorectal cancer (mCRC) patients who achieved a stable disease state after induction chemotherapy. Methods:Data were reviewed from 204 metastatic colorectal cancer pa-tients, who presented a stable disease state after first-line and second-line chemotherapy at Tianjin Medical University Cancer Insti-tute and Hospital. The clinical and pathological characteristics were analyzed. Moreover, we analyzed the significance of maintenance treatment in patients with certain mCRC characteristics. Results:Univariate analysis indicated that the line of chemotherapy, levels of CA724, CEA, and CA19-9, and platelet-to-lymphocyte ratio (PLR) were considered prognostic factors of treatment after induction che-motherapy. According to the multivariate analysis, first-line chemotherapy, as well as low levels of CA19-9 and PLR, with maintenance treatment after the induction chemotherapy was significantly associated with better survival. Among the patients with high levels of PLR, those who underwent maintenance treatment achieved a progression-free survival of 13.43 months (versus 10.63 months in pa-tients from the observation group, P=0.003). Conclusion:The levels of CA19-9 and PLR, and treatment after chemotherapy were signif-icant prognostic factors for mCRC patients who achieved a stable disease state after induction chemotherapy. These patients, especial-ly those with high PLR, could benefit from the maintenance treatment.

Objective To study the function of vascular endothelial growth factor (VEGF) in type 2 diabetes model rats and its effect on focal cerebral ischemia induced by middle cerebral artery occlusion in these rats. Methods Focal cerebral ischemia was induced by middle cerebral artery occlusion for 6 hours in type 2 diabetes rats and normal control rats.Blood vessels morphology was examined by ink perfusion,infarct size was measured by TTC and expression of VEGF and CD34 were evaluated by immunohistochemistry staining. Results Ink perfusion revealed increased number of small vessels in type 2 diabetes rats. Infarct size was significantly smaller in type 2 diabetes rats ( ( 80. 07 ± 11.21 ) mm3 ) than that in normal controls ((98. 91 ± 14. 86) mm3,t = 2.48,P = 0. 0326). There were more hemorrhage lesions in the ischemic hemisphere in type 2 diabetes rats when comparing with the controls. VEGF and CD34 showed significantly higher expression in type 2 diabetes rats than in normal controls. Conclusions High expression of VEGF and CD34 are found in type 2 diabetes rats after middle cerebral artery occlusion. There is cerebrolvascular remodeling in diabetes rats. While this diabetes-induced remodeling appears to prevent infarct expansion,the changes also increase the risk of hemorrhagic transformation. The latter may result in poor prognosis.

Objective: To observe the effects of Yanggan Lidan Granule (YGLDG), a compound traditional Chinese herbal medicine, on insulin resistance in guinea pigs with induced cholesterol gallstones. Methods: Eighty guinea pigs were randomly divided into normal control group, untreated group, YGLDG group and ursodeoxycholic acid (UDCA) group, with 20 guinea pigs in each group. Except the normal control group, gallstones were induced by high-cholesterol diet in the guinea pigs. The guinea pigs in the normal control group and the untreated group were administered with normal saline. UDCA and YGLDG were given to the guinea pigs in the corresponding groups for seven weeks. Eight guinea pigs of each group were used to measure the glucose infusion rate (GIR) by using hyperinsulinemic-euglycemic clamp technique. At the end the guinea pigs were killed and their gallstone formation was observed. Results: The gallstones in guinea pigs were identified as cholesterol stones by qualitative analysis through infrared spectrum. The incidence rate of cholelithiasis of the untreated group was 82.35% . The GIR of guinea pigs in the untreated group was obviously lowered down as compared with the normal control group. Compared with the untreated group, the GIRs of the YGLDG group and the UDCA group were obviously increased, especially in the YGLDG group. Conclusion: YGLDG may improve insulin resistance in guinea pigs with cholesterol gallstones by elevating GIR obviously.

OBJECTIVE:To establish the method for the determination of mildronate in human plasma and urine,and to study the pharmacokinetic characteristics in healthy volunteers. METHODS:After precipitating plasma and urine sample,LC-MS/MS method was adopted. Dikma Diamonsil C18 column was used with mobile phase consisted of methanol-water(containing 0.2% for-mic acid,0.3% ammonium acetate)(31∶69,V/V)at the flow rate of 0.6 ml/min. ESI was adopted in MRM mode,by using nega-tive ion. The ion for quantitative analysis were m/z 147.10→58.20 (mildronate) and m/z 152.00→110.10 (internal standard,acet-aminophen). The pharmacokinetic parameters of mildronate with single administration and multiple administration were calculated by using DAS 2.1 software and compared. RESULTS:The linear range of mildronate in plasma were 0.02-20 ng/ml(r=0.999 3) and in urine were 0.05-40 ng/ml(r=0.998 2). The lowest limits of quantitation were 0.02 and 0.05 ng/ml. Precision and recovery met the requirements of biological specimen determination,and endogenous impurities hadn’t effect on the determination. The main pharmacokinetics parameters of low-dose,medium-dose and low-dose(250,500,750 mg)of mildronate in plasma with single ad-ministration were as follows:t1/2 were(3.39±0.81),(5.52±0.57)and(5.32±0.96)h;tmax were(0.80±0.45),(1.38±0.43)and (1.10±0.36)h;cmax were(4.17±1.46),(8.08±1.04)and(15.04±1.86)ng/ml;AUC0-36 h were(24.55±5.81),(45.50±7.07)and (85.60 ± 13.09)ng·h/ml. In the dose range,cmax,AUC0-36 h h had a linear relationship with dose (R2 were 0.974 5 and 0.968 3). The main pharmacokinetic parameters of low-dose of mildronate with multiple administration after keeping stable were as follows:cmin was(0.28 ± 0.10)ng/ml;AUCs was(38.78 ± 4.18)ng·h/ml;cs was(1.62 ± 0.17)ng/ml;DF was(3.81 ± 1.14);t1/2 was(6.17 ± 1.46)h;tmax was(1.20 ± 0.33)h;cmax was(6.46 ± 1.96)ng/ml;AUC0-36 h was(40.33 ± 4.65)ng·h/ml;accumulation factor of cmax and AUC were(1.73±0.90)and(1.64±0.40). Compared with single administration,t1/2,cmax and AUC of mildronate with multiple admin-istration after keeping stable all changed,and tmax had no signifi-cant difference. After single administration,26 h accumulative excretion rate of those groups were (0.004 009 ± 0.001 1)%, (0.004 026±0.001 01)% and(0.003 858±0.000 68)% respec-tively. CONCLUSIONS:Established method is sensitive,accurate and specific,and suitable for the determination of mildronate concentration in human plasma and urine and pharmacokinetics study. Mildronate capsule shows certain accumulation effect in healthy volunteers,and linear pharmacokinetic characteristics.
