Objective To investigate whether emergency percutaneous coronary intervention(PCI) could influence the BNP level in patients with ST-segment elevation myocardial infarction(STEMI).Methods We enrolled 193 patients who were admitted with STEMI.The BNP levels were measured at admission.All patients underwent routine clinical laboratory tests in the first day of hospitalization.Ninety-two patients underwent emergency PCI and the other 101 patients received conservative medicine treatment.The patients who had emergency PCI were divided into two subgroups according to the time between symptom onset and PCI started(ictus time 0-3 h,n=42;ictus time 3-6 h,n=50) for analysis.Results BNP levels were significantly lower in patients undergoing PCI when compared with conservative medicine treatment(261.0?410.9 ng/L vs 921.5?1126.7 ng/L,P

Objective To explore the risk factors and outcome of stroke-associated pneumonia (SAP) in emergency ward. Methods The baseline characteristics and laboratory data of 306 patients with stroke in emergency ward of our hospital from April, 2014 to December, 2016 were reviewed. Patients were allocated into SAP group (n=120) and non-SAP group (n=186). The multivariable Logistic regression was applied to investigate risk factors for the progression and death of SAP. Results Totally, 120 (39.2%) patients developed SAP, in which 34 (28.3%) cases died. There were significant differences in age, the scores of Glasgow Coma Score (GCS), Sequential Organ Failure As-sessment (SOFA) and National Institute of Health Stroke Scale (NIHSS), and mechanical ventilation, dysphagia, antiacid and tube feeding (P<0.05). The multivariable Logistic regression analysis revealed that age over 65 years, hypertension, GCS<9, NIHSS, dysphagia and anti-acid were the risk factors for the development of SAP;the SOFA, NIHSS>15 and mechanical ventilation were the risk factors for 30-day mortality in SAP group. Conclusion SAP is a severe complication of stroke, it is associated with a variety of risk factors that affect its out-come in emergency ward.

Aim To investigate whether EGCG regu-lates ABCA1 expression by influencing the expression of miR-33 a to promote cholesterol efflux from macro-phages. Methods THP-1 macrophage-derived foam cells were established by co-incubated with oxLDL, and then treated with EGCG, and miR-33a expression was detected with Real-time PCR. THP-1 macrophage-derived foam cells were randomly divided into the fol-lowing groups: control group, 50 μmol · L-1 EGCG treatment group, 50 μmol · L-1 EGCG +80 nmol · L-1 miR-33a mimic treated group. Real-time PCR and Werstern blot was used to detect ABCA1 mRNA and protein expression, Oil Red O staining and high per-formance liquid chromatography were used to detect in-tracellular lipid content, and [3H] assay was used to determine cellular cholesterol efflux. Results EGCG could downregulate miRNA33 a expression in a dose-and time-dependent fashion within safe doses. EGCG significantly upregulated ABCA1 mRNA and protein expression, which could be inhibited after miRNA33 mimic transfected into cells, however. EGCG may re-duce lipid accumulation in THP-1 macrophage-derived foam cells, and this effect could also be weakened after miRNA33 mimic transfected. EGCG could reduce the accumulation of intracellular cholesterol,which was re-lated with EGCG promoting intracellular cholesterol ef-flux , and excess miRNA33 a transfected into cells could inhibit intracellular cholesterol efflux. Conclusion EGCG may upregulate ABCA1 expression by reducing miRNA33a generation, resulting in the promotion of cholesterol efflux from macrophages, which may be one of the molecular mechanisms of EGCG anti-atheroscle-rotic effect.

Objective To investigate the effect of renal sympathetic denervation (RSD) on the activity of renalase in dogs with chronic heart failure (CHF).Methods After induced by abdominal aorta constriction,dogs were divided into three groups according to whether they underwent double renal artery ablation:2 dogs in control group,2 dogs in sham-operated group (no renal artery ablation),and 5 dogs in RSD group (renal artery ablation).Plasma noradrenaline (NE),B-type natriuretic peptide (BNP),and renalase were determined in 5 dogs with RSD (RSD group),2 control dogs (control group),and 2 shamoperated dogs (sham-operated group).Results NE,BNP and heart rate were significantly higher and renalase was lower in CHF group than those in control group (all P ＜ 0.05).Compared to the control dogs with CHF,the levels of renalase were significantly increased in 6 weeks after RSD [(1 948.78 ±49.19) ng/ml vs (1 847.35 ±20.72)ng/ml,P =0.029],and NE [(166.30 ±7.68)pg/ml vs (181.29 ±8.57)pg/ml],and BNP [(75.10 ± 5.58)lμg/ml vs (89.79 ± 2.04) μg/ml] were decreased in 8 weeks after RSD (all P ＜ 0.05).An decreased trend of the levels of renalase was observed in 8 weeks than in 6 weeks in CHF dogs after RSD,without significant difference (P ＞ 0.05).Conclusions The activity of renalase in dogs with CHF can be affected by RSD.

New Chemical Entities (NCEs) development is a systematic long-term project that involves multiple disciplines. The translation research will help to build an advanced R&D system from the basic laboratory research, preclinical studies and clinical evaluation to clinical application of drug, for the purpose of shortening the R&D cycle and accelerate the launch of new drugs. In new drug R&D and its clinical application, drug disposition (absorption, distribution, metabolism, excretion, ADME) properties are important criteria for assessing drug-likeness of candidates. ADME evaluation of NCEs plays an important role in the translation research throughout innovative drug R&D process. Therefore, ADME evaluation at the early stage of drug design and development will be helpful to improve the success rate and reduce costs, and further access to safe, effective drugs.

CYP2D6 is an important drug-metabolizing enzyme. The polymorphism of CYP2D6 leads to metabolism difference and the different reactions of drugs in the individuals and different races are normal phenomenon in clinical medication. CYP2D6*10 is an important subtype in Asian people and 51.3% Chinese are classified with this subtype. To obtain recombinant active CYP2D6*1/CYP2D6*10 in baculovirus system by optimizing coexpression with CYPOR, and detect their activity to catalyze dextromethorphan, three recombinants pFastBac-CYP2D6*1, pFastBac-CYP2D6*10 and pFastBac-CYPOR were constructed and transformed into DH10Bac cell to obtain the recombinant Bacmid-CYPOR, Bacmid-CYP2D6*1 and Bacmid-CYP2D6*10. And then the recombinant CYP2D6*1 and CYP2D6*10 virus were obtained by transfecting Sf9. Then homogenate protein activity was determined with dextromethorphan as substrate. The multiple of infection (MOI) and its ratio of recombinant CYP2D6 virus to CYPOR virus were adjusted by detecting the activity of the homogenate protein. The Km and Vmax are 26.67 +/- 2.71 micromol x L(-1) (n=3) and 666.7 +/- 56.78 pmol x nmol(-1) (CYP2D6) x min(-1) (n=3) for CYP2D6*1 to catalyze dextromethaphan. The Km and Vmax are 111.36 +/- 10.89 micromol x L(-1) (n=3) and 222.2 +/- 20.12 pmol x nmol(-1) (CYP2D6) x min(-1) (n=3) for CYP2D6*10 to catalyze dextromethorphan. There is significant difference between CYP2D6*1 and CYP2D6*10 for Vmax and Km (P < 0.01). The clearance ratio of CYP2D6*1 is 25.0 and the clearance ratio of CYP2D6*10 is 2.0. The expressed CYP2D6*1 and CYP2D6*10 are useful tools to screen the metabolism profile of many xenobiotics and endobiotics in vitro, which are benefit to understand individual metabolism difference.

OBJECTIVETo observe the effects of electroacupuncture (EA) at different acupoints on apoptosis-related serum and expression of microRNA (miRNA) in rats with myocardial ischemia, so as to explore its mechanism of action.

METHODSA total of 48 male Wistar rats were randomly divided into a normal group, a model group, a Neiguan group and a acupoint compatibility group, 12 rats in each group. Isoprenaline hydrochloride (ISO) with a daily dose of 2 mg/kg was subcutaneously injected for 14 days to establish the myocardial ischemia model in the model group, Neiguan group and acupoint compatibility group. Rats in the normal group were subcutaneously injected with an equal volume of normal saline. After modeling, rats in the Neiguan group were treated with EA at "Neiguan" (PC 6), while rats in the acupoint compatibility group were treated with EA at "Guanyuan" (CV 4), "Zusanli" (ST 36) and "Neiguan" (PC 6). Rats in the normal group and model group were treated with immobilization, once day for 21 days. The contents of creatine kinase-MB (CK-MB), vascular cell adhesion molecule-1 (VCAM-1) and endothelin-1 (ET-1) in serum were detected by enzyme-linked immunosorbent assay (ELISA); apoptosis index (AI) of myocardial cells was detected by TUNEL method; the expressions of miRNA-1, miRNA-133, miRNA-208 and miRNA-499 were detected by real-time PCR method.

RESULTSCompared with the normal group, the serum CK-MB, VCAM-1 and ET-1 were significantly increased in the model group, Neiguan group and acupoint compatibility group (all P < 0.01), and the apoptosis index was significantly increased (all P < 0.01). The CK-MB, VCAM-1 and ET-1 in the Neiguan group and acupoint compatibility group were significantly lower than those in the model group (all P < 0.01); the AI was reduced, which was more significant in the acupoint compatibility group (P < 0.05). Compared with the normal group, the expression of miRNA-133 was reduced (P < 0.01) and those of miRNA-208, miRNA-1 and miRNA-499 were significantly increased in the model group (all P < 0.01). Compared with the model group, the expression of miRNA-133 was increased (both P < 0.01) and that of miRNA-208, miRNA-1 and miRNA-499 were significantly reduced (all P < 0.01) in the Neiguan group and acupoint compatibility group. Compared with the Neiguan group, the expression of miRNA-133 was increased (P < 0.01) and those of miRNA-208, miRNA-1 and miRNA-499 were significantly reduced in the acupoint compatibility group (P < 0.01, P < 0.05).

CONCLUSIONEA at acupoints, especially acupoint compatibility group, could effectively prevent and treat myocardial ischemia, and the protective effect is possibly correlated to the double regulation on increasing the expression of miRNA-133 and inhibiting the expression of miRNA-1, miRNA-208, miRNA-499.

OBJECTIVETo compare the clinical effects between ginger-partition moxibustion combined with glucocorticoid and simple oral glucocorticoid for thyreoitis at subacute stage.

METHODSEighty-one patients were randomly divided into an observation group (41 cases) and a control group (40 cases). In the observation group, ginger-partition moxibustion and hormone were applied. Moxa cones were used at local ashi points, Zusanli (ST 36), Guanyuan (CV 4) and Qihai (CV 6), six cones every point, once every other day and three times a week. Besides, 24 mg methylprednisolone tablets were adopted orally every day, and in two weeks the dose was 16 mg/d, in four weeks 8 mg/d, in six weeks 4 mg/d; all the patients were observed for 8 week. In the control group, simple methylprednisolone was prescribed orally, and the dose, the usage and treatment time were the same as those in the observation group. Erythrocyte sedimentation rate (ESR), triiodothyronine (T3), thyroxin (T4) and ultra-sensitive thyroid stimulating hormone (TSH) before and after treatment were observed in the two groups, as well as fever, the pain of thyroid gland, the regression time of swelling and adverse reaction.

RESULTSThe time of thyroid gland pain relieved of the observation group was earlier than that of the control group [(3.07 ± 0.78) days vs (3.62 ± 0.92) days, P < 0.05]. After treatment, T3, T4 and ESR were declined apparently (all P < 0.01), and TSH was obviously increased in the two groups (both P < 0.01). After 2-week treatment, ESR in the observation group was lower than that in the control group (P < 0.05). After 4-week treatment, T3, T4, TSH and ESR in the observation group were better than those in the control group (all P < 0.05). After 8 weeks, all indices in the observation group were superior to those in the control group, without statistical significance between the two groups (all P > 0.05). The effects of the observation group in 2 weeks, 4 weeks and 8 weeks were better than those in the control group (all P < 0.05). The cured course was shorter in the observation group than that in the control group (P < 0.05). The adverse reaction rate in the observation group was lower than that in the control group [4.9% (2/41) vs 22.5% (9/40), P < 0.05]. Three months later after treatment, the cured patients were followed. There was no recrudescence in the observation group and three patients caught the disease again in the control group, but there was no statistical significance between the two groups (P > 0.05).

CONCLUSIONGinger-partition moxibustion combined with glucocorticoid achieves better effect than simple oral glucocorticoid for thyreoitis at subacute stage, and the adverse reaction is less, which presents the clinical advantages of the integration of Chinese and western medicine.

AIM: Anti-atherosclerosis effects of Momordica charantia L was further studied in a New Zealand rabbit atherosclerotic model at the basis of anti-inflammation and antioxidant effects. METHODS: Animals were divided into 3 groups: normal group (normal rabbit diet), atherosclerosis group(diet containing 2% cholesterol), and Momordica charantia L group(diet containing 2% cholesterol and 1 5% sarcocarp of Momordica charantia L ). Ninety days later, all animals were sacrificed. The effect of Momordica charantia L on atherosclerosis was evaluated by measuring serum lipid and total cholesterol content of artery wall, observing fatty liver degree, aorta arteriosclerotic area, and the thickness of intima. RESULTS: The level of total serum cholesterol and LDL-C in Momordica charantia L treatment group were obviously lower than those in atherosclerosis group, so were the total cholesterol content of artery wall, fatty liver degree, atherosclerotic area, intima thickness and I/M ratio, but no significantly difference was found between the two groups in TG level. The level of HDL-C in Momordica charantia L treatment group was evidently lower than that in normal control group. CONCLUSION: Momordica charantia L has an anti-atherosclerosis action in rabbits.
