Tianjin Medical Journal 2015;(3):292-295
Objective To explore changes of risk factors between premenopausal and postmenopausal female patients with coronary heart disease (CHD). Methods A total of 283 female patients were divided into CHD group (n=154) and con?trol group (n=129) according to whether they suffered from CHD or not. Patients were further stratified into two groups accord?ing to menopausal situation:premenopausal group (n=78, including premenopausal CHD group of 34 cases and premenopaus?al control group of 44 cases) and postmenopausal group (n=205, including postmenopausal CHD group of 120 cases and post?menopausal control group of 85 cases). Clinical data of age, body mass index (BMI), medical history and menses situation were recorded. The levels of cholesterol (CHO), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipo?protein cholesterol (LDL-C), very low density lipoprotein cholesterol (vLDL-C), apolipoprotein AI (ApoAI), apolipoprotein B (apoB), lipoprotein a (Lpa), homocysteine (HCY) and high-sensitive C-reactive protein (hsCRP) were also detected. Results There were significantly higher levels of age, CHO, TG, LDL-C, vLDL-C, Lpa, ApoB, hsCRP, and the ratio of hypertension history, diabetic history, coronary heart disease family history in CHD group than those of control group. The level of HDLc was significantly lower in CHD group than that of control group. The ratio of hypertension history, diabetic history and levels of CHO, TG, LDL-C, vLDL-C, Lpa, ApoB, hsCRP were significantly higher in both premenopausal and postmenopausal CHD groups than those of their control groups. The level of HDL-C was significantly lower in postmenopausal CHD group than that of postmenopausal control group (P<0.05). Hypertension history, diabetic history and LDL-C were the independent risk fac?tors of premenopausal CHD. Hypertension history, diabetic history and CHO were the independent risk factors of postmeno?pausal CHD, and HDL-C was the protecting factor of CHD. The ratio of hypertension history, the level of CHO and LDL-C were significantly higher in postmenopausal CHD group than those of premonopausal CHD group. Conclusion The abnor?mal blood pressure level and dyslipidemia are more prevalent in postmenopausal female patients with CHD than premeno?pausal female patients. We should control these risk factors to improve the prognosis.

Objective To explore the relationship between plasma mannose-binding lectin (MBL), lipopolysaccharide (LPS) and body mass index in pregnant women with gestational diabetes mellitus (GDM). Methods 45 newly diagnosed GDM pregnant women and 45 healthy women (control group) were selected in this study. Plasma concentration of MBL and LPS were measured. All the groups were sub-divided into obesity (BMI ≥ 25 kg/m2) and non-obesity (BMI < 25 kg/m2) subgroup. The relationships of levels of plasma LPS, MBL with BMI were analyzed. Results The level of plasma MBL in GDM group was significantly lower than that in control group(P < 0.05), while the concentration of LPS in serum was much higher than that in healthy pregnant women (P < 0.05). Pearson analysis showed the level of MBL in GDM group was negatively correlated with BMI(r=-0.28, P<0.05), serum LPS concentration was positively correlated with BMI(r = 0.62, P < 0.05) and LPS was negatively correlated With MBL(r = -0.43, P < 0.05) . The above correlations were not found in control group. Conclusion Serum MBL and LPS maybe two important risk factors for those pregnant women being overweight, and could offer great significance for the prevention and treatment of GDM.

Whole-cell patch-clamp technique was performed on isolated rat DRG neurons to investigate the modulation of DA onGABA-activated membrane currents. It was found that majority of the examined neurons(40/47) were sensitive to GABA, 10-6~ 103mol/L GABA activated a dose-dependent inward current which had an obvious desensitization. In 26 of 40 neurons sensitiveto GABA DA induced a little outward current which had no desentization at all. Others showed no effect obviously. When theneurons were treated with DA 10-7~10-4 mol/L prior to the application of GABA for 30 s, 68% (27/40) GABA-activated mem-brane currents were inhibited, whereas DA10-5 inhibited markedly(33.3%) (x±s).

Objective To investigate the predictive value of the non-invasive indicator deceleration capacity of heart rate (DC) in the sudden cardiac death (SCD) after acute myocardial infarction. Methods A total of 417 myocardial infarc?tion patients with ST-segment elevation in sinus rhythm were enrolled in this study. DC was assessed from data of 24-hour ECG Holter. Regular follow-ups were carried out within 12 months. The SCD events were recorded and compared with pa?tients without SCD. Results During 12 months of follow-up, 20 patients were died due to SCD (4.8%). Compared with sur?vival group, patients showed significantly lower left ventricular ejection fraction (LVEF, 0.393 ± 0.065 vs 0.528 ± 0.042, P<0.05) and DC [(2.85±1.66) ms vs (5.49±1.71) ms,P<0.05]in SCD group. Multivariate Cox proportional hazard regression analysis showed that lower LVEF(<0.35)[RR: 2.167(1.384-4.661), P=0.013]and DC (DC<4.5 ms)[RR: 3.706(2.709-5.374),P=0.020]were risk factors for the occurrence of SCD. The prediction sensitivity by the decreased LVEF and DC was 52.1%and 76.4%respectively, and the specificity was 84.5%and 86.1%respectively. Conclusion The decreased value of DC after acute myocardial infarction can predict the SCD events.

Objective To evaluate the changes of platelet aggregation rate and short-term prognosis after the application of colopidgrel with booster doses or replaced by ticagrelor for ACS patients with CYP2C19 medium-metabolized genotype). Method A total of 302 patients with medium-metabolized genotype were randomly divided into colopidgrel group (75 mg/bid) and ticagrelor group (90 mg/bid). Patients in both groups accepted other conventional treatments of coronary heart disease and accompanied diseases. The platelet aggregation rates and platelet inhibition rates were observed before and after the treatment. The incidence of adverse events was followed up within 1 m. Results After one-week treatment, the platelet aggregation rates of the inducement with 5 μmol/L ADP had statistical significance between colopidgrel group and ticagrelor group ( P = 0 . 019 ) and the platelet inhibition rates had statistical significance difference between the two groups (P = 0.000). No severe adverse events occurred within one-month follow-up and 10 dyspnea patients were all in ticagrelor group. Conclusions Compared with booster doses of clopidogrel, ticagrelor presents obvious inhibitory effect on platelet of patients with medium-metabolized of ACS but it increases the incidence of dyspnea.

OBJECTIVE:To investigate the effects of Cangfu daotan decoction combined with Clomiphene citrate capsule on sex hormone level and endometrial receptivity in patients with polycystic ovary syndrome (PCOS) combined infertility. METH-ODS:A total of 116 PCOS patients with infertility in the First Affiliated Hospital of Guiyang College of TCM from Jan. 2014 to Dec. 2014 were divided into observation group and control group according to random number table,with 58 cases in each group. Both groups received hormone regulation therapy since the fifth day of menstruation. Control group was given Clomiphene citrate capsule 50 mg,qd;observation group was additionally given one dose of Cangfu daotan decoction,400 mL after decocted with wa-ter,bid,on the basis of control group. Both groups were treated for 3 cycles of menstruation. The levels of serum sex hormone (E2,LH),endometrial thickness(Em),endometrial spiral arterial pulsatility index(PI)and resistance index(RI)were compared between 2 groups before and after treatment. The ovulation rate and pregnancy rate were compared between 2 groups after 1-year follow-up. RESULTS:Before treatment,there was no statistical significance in E2,LH,Em,PI or RI between 2 groups (P>0.05). After treatment,the levels of E2 and LH as well as Em in 2 groups were increased significantly,while PI and RI were de-creased significantly;the observation group was significantly better than the control group,with statistical significance(P<0.06). After 1-year follow-up,there was no statistical significance in ovulation rate between 2 groups (P>0.05). The pregnancy rate of observation group was 41.38%,which was significantly higher than that of control group (22.41%),with statistical significance (P<0.05). CONCLUSIONS:Cangfu daotan decoction combined with Clomiphene citrate capsule can effectively regulate serum sex hormone levels of PCOS patients with infertility,and improve endometrial receptivity so as to increase pregnancy rate.
