Résumé

<p><b>OBJECTIVE</b>To observe the effect of total ginsenosides (TG) on monocrotaline (MCT) induced right ventricular hypertrophy rats, and to explore its correlation with calcineurin (CaN) pathway.</p><p><b>METHODS</b>Fifty male Sprague Dawley rats were randomly divided into the normal control group, the MCT model group, and the low, middle, high dose TG treatment groups, 10 in each group. All medication was performed by peritoneal injection for 18 days. Right ventricular peak systolic pressure (RVSP), right ventricular hypertrophy index (RVHI), and right ventricular weight/body weight (RVW/BW) were measured. Intracellular free calcium concentrations were measured by Ca2+ fluorescence indicator Fura2/AM. The atrial natriuretic factor (ANF) and CaN mRNA expression of the myocardial tissue were quantitatively analyzed by Real-time PCR. The protein expression of CaN was detected by Western blot.</p><p><b>RESULTS</b>Compared with the MCT model group, preventive treatment of TG at the 3 doses could significantly reduce RVSP, RVHI, RVW/BW, and ANF mRNA expression, and decrease Ca2+ concentration in myocardial cells, CaN mRNA and protein expression in the myocardial tissue.</p><p><b>CONCLUSION</b>TG could obviously improve MCT-induced right ventricular hypertrophy, which was possibly achieved through suppressing MCT-activated CaN signal transduction.</p>

Résumé

<p><b>OBJECTIVE</b>To observe the effect of xuebijing Injection (XI) on perioperative coagulation and inflammatory reaction in senile patients receiving total hip arthroplasty (THA).</p><p><b>METHODS</b>Totally eighty patients receiving THA at Luoyang Orthopedics Hospital, 65 to 85 years old, were randomly assigned to the control group (40 cases) and the treatment group (40 cases). All patients received routine perioperative therapies. Those in the treatment group received XI (adding 50 mL XI in 100 mL normal saline, 30 min each time). XI was continually injected after THA, twice daily for 3 successive days. Blood samples were harvested on the morning of the 2nd admission day (TO), immediately after operation (T1), on the morning of the 3rd day after operation (T3), and on the morning of the 5th day after operation (T4) to detect prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT), levels of FIB and D-dimer (D-D), changes of white blood cell (WBC), neutrophils (N), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and IL-6. Complications of surgery were compared between the two groups.</p><p><b>RESULTS</b>There was no statistical difference in operation time, intraoperative blood loss, and blood transfusion between the two groups (P >0.05). Compared with TO in the same group, WBC, N, CRP, ESR, IL-6, PT, TT, and D-D all increased in the control group at T1-T4 (P < 0.05); APTT increased at T1-T2 (P <0.05); FIB increased at T1-T3 (P <0.05). WBC, N, IL-6, PT, and D-D all increased in the treatment group at T1-T3 (P <0.05); CRP and ESR increased at T1-T4 (P < 0.05); TT increased at T1-T2 (P <0.05); APTT and FIB increased at T1 (P <0.05). Compared with the control group at the same time period, WBC, N, CRP, and IL-6 all decreased in the treatment group at T1-T4 (P <0.05), ESR decreased at T3-T4 (P <0.05); PT and TT decreased at T1-T3 (P <0.05); FIB and D-D decreased at T2-T4 (P<0.05). The occurrence of each complication was significantly lower in the treatment groups than in the control group.</p><p><b>CONCLUSION</b>XI could improve the perioperative high coagulation state of senile THA patients, inhibit inflammatory reactions, and reduce complications.</p>

Résumé

<p><b>OBJECTIVE</b>To observe the effect of total ginsenosides (TG) on right ventricular hypertrophy induced by monocrotaline (MCT) in rats, and study its relationship with the nitric oxide pathway.</p><p><b>METHOD</b>Male Sprague Dawley rats were randomly divided into the control group, the MCT model group, TG-treated (20, 40, 60 mg kg-1 d-1) groups, and the L-arginine (L-arg) th NO release, T + L-N and L-a + L-N groups were wi th NOS into study TG's effect 200 mg kg-1 d-1 group. Besides, and its relationship wi also set, intraperitoneally injected with TG 40 mg kg-1 d -1 and L-arg 200 mg kg-1 - d-1, and orally administered hibitor L-NAME 20 mg kg-1 d-1. After all of the groups were given drugs for 18 d, their right ventricular peak systolic pressure (RVSP) ventricular hypertrophy index (RVHI) and RVW/BW were determined. Ultra-structure of myocardial cells was observed with transmission electron microscope. The NO2 -/NO3 - content in myocardial tissues were detected with the nitrate reduction method. ANF and eNOS mRNA expressions in right ventricle tissues were detected by using real-time RT-PCR.</p><p><b>RESULT</b>Low, middle and high doses of TG and L-arg preventive administration could significantly reduce RVSP, RVHI, RVW/BW and ANF mRNA expressions (P < 0. 05) , and ameliorate cellular mitochondrial swelling and degeneration. L-NAME could prevent the effect of L-arg on above indexes, whereas L-NAME of the same dose could not impact the reducing effect of TG 40 mg kg -1 on above indexes. TG 60 mg kg -1 could raise eNOS mRNA expression, but TG 20 mg kg-1 and 40 mg kg-1 showed no effect.</p><p><b>CONCLUSION</b>TG can significantly attenuate MCT-induced right cardiac hypertrophy in rats. Its anti-hypertrophic effect is partially realized through NO.</p>
