OBJECTIVETo observe the therapeutic effects of Berberine Capsule (BC) on patients with mild hyperlipidemia.

METHODSTotally 102 mild hyperlipemia patients were recruited. All patients were suggested to have proper diet and physical activity as basic therapy for 1 month of run-in period. Totally 97 patients completed it. Then they were randomly assigned to the berberine group (the treatment group, 49 cases) and the placebo group (the control group, 48 cases). Patients in the treatment group took BC 300 mg, while those in the control group took placebo 300 mg, thrice per day for 3 successive months. Then placebos and BC were interrupted for 2 months (as washout period). All subjects received only diet control and physical activity during washout period. After washout period, placebos and BC were re-administered to all patients in the same way for 3 months. Body mass index (BMI), fasting plasma glucose (FPG), TG, TC, LDL-C, and HDL-C were assessed after run-in period, washout period, at month 1, 2, 3 after the first therapy, at month 1, 2, 3 after second treatment, respectively.

RESULTSCompared with the end of run-in period, TG, TC, and LDL-C decreased, and HDL-C increased in the treatment group (P < 0.05) after first 3 months of treatment. Compared with 3 months after the first therapy, TG, TC, and LDL-C increased and HDL-C decreased in the treatment group after washout period (P < 0.05). Compared with the end of wash- out period, TC and LDL-C decreased in the treatment group at month 2 after second treatment (P < 0.05); TG, TC, and LDL-C decreased (P < 0.01, P < 0.05), and HDL-C increased (P < 0.05) at month 3 after second treatment. Compared with the control group at month 3 after second treatment, TG, TC, and LDL-C all decreased, and HDL-C increased in the treatment group (all P < 0.05).

Objective To compare the effects of upstream versus downstream tirofiban on tissure level perfu-sion and troponin Ⅰ release in high-risk non-ST-segment elevation acute coronary patients treated with percutaneous coronary intervention. Methods We randomized 138 non-ST-segment elevation acute coronary syndrome patients un-dergoing PCI to receive upstream(in the coronary care unit) and downstream(just prior to PCI) tirofiban. We com-pared the effects between the two drug regimens on tissue-level peffusion using Thrombolysis In Mycardial Infarction (TIMI) fram count,the TIMI myocardial perfusion grade(TMPG) and cardiac tropinin Ⅰ (cTn Ⅰ) release before and after PCI. Results There was no significant difference between two groups in TIMI 3 flow(P>0.05). High percent-age of TMPG 3 perfusion were observed in upstream tirofiban group than in downstream tirofiban group (P < 0.05). Post-procedual cTnI elevation was significantly less frequent among patients in the upstream group (P < 0.05). The cTnI level after PCI was significantly lower with upstream tirofiban compared with downstream tirofiban group (P<0.05). Conclusion Among high-risk non-ST-segment elevation ACS patients treated with an early invasive strategy, upstream tirofiban is associated with improved tissue-level perfusion and attenuated myocardial damage.

In this study, we designed and synthesized 12 novel aloperine derivatives with different core structures. Among them, compound 3 with a ten-membered ring core was obtained through a special ring expansion reaction after γ-H Huffman elimination of quaternary ammonium salt, and the structure was verified by X-single crystal diffraction. Furthermore, their antiviral activity against human β-coronavirus HCoV-OC43 was evaluated by CCK-8 assay. Quaternary ammonium salt 2a and 3 had a good inhibitory effect against HCoV-OC43, and 2a had the highest anti-HCoV-OC43 activity with an EC₅₀ values of 3.77 μmol·L^-1 and a SI value of over 53.1. Schrӧdinger molecular docking results showed that both 2a and 3 might display their anti-HCoV-OC43 activity by directly acting on host TMPRSS2 and SR-B1. The results expanded the structural types of endocyclic aloperine and the function against coronavirus, and provided useful scientific data for the development of pharmaceutical applications of these compounds.

OBJECTIVETo investigate the impact of the Artemisia annua plant-derived drug, artesunate, on proliferation of primary rat hepatic stellate cells (HSCs), and to analyze the underlying molecular mechanisms of its anti-fibrogenic effects involving the inhibition of transforming growth factor-beta 1 (TGF-b1) expression and secretion in liver.

METHODIsolated, cultured, and activated primary rat HSCs were divided into sixteen groups, including one untreated control group and fifteen artesunate-treated experimental groups with 125, 150, 175, 200 or 225 mumol/L for 24, 48 or 72 hours. The rate of cellular proliferation was measured using the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. TGF-b1 mRNA expression was evaluated by reverse transcription-polymerase chain reaction and protein expression was evaluated by Western blotting. Enzyme-linked immunosorbent assay was used to evaluate secreted levels of TGF-b1 protein.

RESULTSArtesunate significantly inhibited proliferation of cultured HSCs in a dose- and time-dependent manner (all, P less than 0.01). After 24 hours of exposure, the inhibition ratios of the various artesunate concentrations were: 6.06%+/-1.44% (125 mumol/L), 21.47%+/-5.57% (150 mumol/L), 42.00%+/-7.36% (175 mumol/L), 67.12%+/-4.55% (200 mumol/L), and 79.83%+/-3.67% (225 mumol/L). Artesunate significantly inhibited the TGF-b1 mRNA expression in HSCs, and the higher the drug concentration, the higher the degree of inhibition (all, P less than 0.01). In addition, artesunate significantly inhibited the expression of intracellular and secreted TGF-b1 protein (all, P less than 0.01). In response to artesunate (mumol/L concentrations), the TGF-b1 levels were (164.24+/-6.88) pg/ml (0μmol/L), (102.68+/-4.45) pg/ml (150μmol/L), (86.54+/-5.56) pg/ml (175μmol/L), and (56.55+/-5.66) pg/ml (200μmol/L).

CONCLUSIONArtesunate exerts anti-fibrogenic effects on HSCs in vitro, possibly by reducing the expression, translation and secretion of TGF-b1.
