Objective:To investigate the therapeutic effect of cardiac rehabilitation exercise on ventricular remodeling in patients with acute myocardial infarction undergoing percutaneous coronary intervention.Methods:A total of 100 patients with acute myocardial infarction undergoing percutaneous coronary intervention who received treatment in Wenzhou Central Hospital from June 2018 to June 2019 were included in this study. They were randomly divided into a rehabilitation group and a conventional treatment group ( n = 50/group). Patients in the conventional treatment group underwent conventional postoperative rehabilitation education while those in the rehabilitation group received targeted cardiac rehabilitation exercise. After surgery, all patients were followed up for 12 months. Real time three-dimensional echocardiography was used to evaluate ventricular remodeling (left ventricular ejection fraction, left ventricular end-diastolic volume , left ventricular end-systolic volume, left ventricular remodeling index) and ventricular synchrony (Tmsv-16dif, Tmsv-16sd, Tmsv16-dif%, Tmsv16-sd%) before and 3, 6 and 12 months after surgery. In addition, serum levels of ventricular remodeling indexes (fibroblast growth factor 23, PICP and PIIINP) were measured. The incidence of cardiovascular end-point events within 12 months was calculated. Results:At 3, 6 and 12 months after surgery, left ventricular ejection fraction was (51.81 ± 5.43)%, (55.88 ± 5.46)%, (55.63 ± 5.57)% in the rehabilitation group, which was significantly higher than (47.16 ± 5.38)%, (52.31 ± 5.44)%, (51.84 ± 5.59)% respectively in the conventional treatment group ( t = 4.302, 3.275, 3.396, all P < 0.05). At 3, 6 and 12 months after surgery, left ventricular end-diastolic volume was (124.65 ± 15.56) mL, (98.54 ± 14.54) mL, (99.82 ± 13.18) mL, respectively in the rehabilitation group, which was lower than (132.64 ± 16.58) mL, (112.55 ± 15.61) mL and (114.84 ± 17.35) mL, respectively in the conventional treatment group ( t = 2.485, 4.644, 4.874, all P < 0.05). At 6 and 12 months after surgery, left ventricular end-systolic volume was (52.26 ± 5.48) mL and (52.15 ± 5.32) mL respectively in the rehabilitation group, which was significantly lower than (57.92 ± 5.46) mL and (58.51 ± 5.72) mL in the conventional treatment group ( t = 5.174, 5.757, both P < 0.05). At 6 and 12 months after surgery, left ventricular remodeling index was (1.75 ± 0.42) g/mL and (1.74 ± 0.35) g/mL respectively in the rehabilitation group, which was significantly higher than (1.52 ± 0.37) g/mL and (1.50 ± 0.32) g/mL, respectively in the conventional treatment group ( t = 2.906, 3.579, both P < 0.05). At 3, 6 and 12 months after surgery, Tmsv-16dif ( t = 2.753, 4.283, 4.088, all P < 0.05), Tmsv-16sd ( t = 5.134, 4.326, 4.670, all P < 0.05), Tmsv-16dif% ( t = 7.714, 8.587, 7.800, all P < 0.05) and Tmsv16-sd% ( t = 9.004, 14.061, 10.305, all P < 0.05) respectively in the rehabilitation group, were significantly lower than those in the conventional treatment group. At 3, 6 and 12 months after surgery, fibroblast growth factor 23 ( t = 6.303, 5.053, 4.619, all P < 0.05). PICP ( t = 3.772, 2.798, 3.788, all P < 0.05) and PIIINP ( t = 3.110, 5.912, 4.294, all P < 0.05) in the rehabilitation group were significantly lower than those in the conventional treatment group. Within 12 months, the total incidence of cardiovascular end-point events in the rehabilitation group [12.00% (6/50)] was significantly lower than that in the conventional treatment [32.00% (16/50)] ( χ2 = 5.828, P < 0.05). Conclusion:Cardiac rehabilitation exercise can improve ventricular remodeling and synchrony in patients with acute myocardial infarction undergoing percutaneous coronary intervention and reduce the incidence of cardiovascular end-point events.

BACKGROUND: Effects of Pericarpium aurantiin water extract on sleeping and spontaneous activity in Kunming mice has been investigated in three experiments, that is, the experiments of sleeping time due to supraliminal and subliminal dosage of sodium pentobarbital, and shaking cage for energy transducer, respectively.OBJECTIVE: To observe the influence of Pericarpium aurantiin water extract on sleeping and spontaneous activity of Kunming mice.DESIGN:Randomized controlled trial.SETTING: The Staff Rooms of Pathology, Physiology and Pharmacology in Gannan Medical College.MATERIALS: The experiment was conducted in the Central Laboratory of Science Research, Gannan Medical College from January through February 2005. Ninety adult Kunming mice, grade of clearness, were enrolled and randomly divided into three groups with 30 mice for each experiment:10 in control group, 10 in large-dosage group and 10 in small-dosage group.METHODS: ① In energy transforming trial, spontaneous activity of mice was recorded, small wave with wave amplitude ＜ 5 mm was considered as the waveform of gentle activity in mice, such as fur licking and tickling; middle wave with wave amplitude of 5-10 mm as the waveform of moderate activity, such as walking, standing, climbing up and down;large wave with wave amplitude ＞ 10 mm as the waveform of intensive activity, such as running, jumping up and down. Mice in the small-dosage group, large-dosage group and control group were respectively given intraperitoneal injection of 5 mg/g, 10 mg/g Pericarpium aurantiin water extract and equal volume of normal saline, and placed into the cage after 15 minutes. Then, 3 minutes later, waveforms of mice within 15 s was recorded. ② In the experiments on duration of sleep in mice due to supraliminal or subliminal dosage sodium pentobarbital, 0.02 mL/g or 0.01 mL/g sodium pentobarbital (2.5 g/L) were administrated intraperitoneally into mice in the small-dosage, large-dosage and control group 15 minutes after intraperitoneal injection of 5 mg/g, 10 mg/g Pericarpium aurantiin water extract and equal volume of normal saline were given to the three groups, respectively. Subsequently, comparisons of the number of sleeping mice, time to falling asleep, and sleeping time were carried out among the three groups.MAIN OUTCOME MEASURFS: ① Times of spontaneous activity, ②Sleeping time due to supraliminal dosage of sodium pentobarbital, ③ Duration of sleep due to subliminal dosage of sodium pentobarbital.RESULTS: All the mice were involved in the result analysis without loss.① There were fewer middle and large waves in the small-dosage and largedosage groups as compared with that in the control group (90.5±14.7,58.3±12.5, 45.6±10.1, t=2.341-3.215; P ＜0.05 or P ＜0.01), indicating that Pericarpium aurantiin water extract can evidently inhibit spontaneous activities in mice. ② In comparison with the control group, the time to falling asleep and the duration of sleep due to supraliminal dosage of sodium pentobarbital were shortened and prolonged significantly, respectively,in the small-dosage and large-dosage groups. ③ In comparison with the control group, the time to falling asleep and duration of sleep due to subliminal dosage of sodium pentobarbital were shortened and prolonged significantly, respectively, in the small-dosage and large-dosage groups.CONCLUSION: Pericarpium aurantiin water extract can prolong the duration of sleep and inhibit the spontaneous activities of Kunming mice,which is in cooperation with sodium pentobarbital in central inhibition.

BACKGROUND:Cel membrane microparticles CD31 and CD54 lead to microvascular injury in the femoral head by mediating vascular inflammatory response, promoting blood clotting, affecting vasomotion and promoting vascular endothelial injury. Studies have verified that membrane particles play an important role in steroid-induced necrosis of the femoral head, but there is no studies concerning relationship between microparticles and alcohol-induced avascular necrosis of femoral head. METHODS/DESIGN:This is a randomized control ed animal study. Healthy male Wistar rats wil be randomly assigned to two groups. In the model group, rats wil be intragastrical y administered hard liquor for 6 consecutive months to prepare models of alcohol-induced avascular necrosis of the femoral head. Blank controls wil be intragastrical y given an equal volume of physiological saline. In 1-6 months of intervention, six rats wil be randomly selected from each group every month. Blood wil be col ected separately. Flow cytometry wil be used to detect serum cel membrane particles CD31, CD54 levels. Bilateral femoral head wil be fixed, decalcified, embedded in wax, and then sections. After hematoxylin-eosin staining, empty bone lacuna wil be quantified under a light microscope to identify femoral head necrosis. Verhoff’s staining and MSB microthrombosis staining wil be used to observe microvascular injury and microvascular thrombosis in the femoral head, and to analyze the correlation of CD31 and CD54 levels with femoral head necrosis, vascular endothelial injury and microvascular thrombosis. DISCUSSION:This study wil investigate the effects of CD31 and CD54 on alcohol-induced avascular necrosis of the femoral head, explore the pathogenesis of alcohol-induced avascular necrosis of the femoral head, provide a new theoretical basis for early diagnosis and early treatment, and may provide a new target for its treatment. ETHICS APPROVAL:The protocol has been approved by the Animal Experimental Ethics Committee of Inner Mongolia Medical University (approval number YKD2016154). Experimental procedures and materials of rats wil be in accordance with the Guide for the Care and Use of Laboratory Animals, which is consistent with the guide of National Institutes of Health. Subject headings:Femur Head Necrosis;Membrane Proteins;Tissue Engineering

BACKGROUND:The relationship between long-term heavy drinking and alcohol-induced necrosis of the femoral head has long been clear, but thepathogenesis of alcohol-induced necrosis of the femoral head is currently not fuly understood.
OBJECTIVE:To establish a rat model of alcohol-induced avascular necrosis of femoral head and to study its pathogenesis.
METHODS: Eighty Wistar rats were randomly divided into experimental and control groups (40 rats per group). Rats in the experimental group were intragastricaly administered strong wine 10 mL/kg, once a day, for 6 consecutive days. Rats in the control group were given physiological saline 10mL/kg, once a day, for 6 consecutive days. Bilateral femoral heads were randomly colected from six rats every month for histomorphological observation.
RESULTS AND CONCLUSION:(1) Osteonecrosis: in the experimental group, at 3 months, trabecular bone became thin, arranged disorderly, and the number of empty lacuna began to increase. At 6 months, typical osteonecrosis appeared, and vacant lacunaes increased significantly. In the control group, trabecular bone was complete and neatly arranged. Osteocytes were visible in bone lacuna, and normal morphology of cels was seen. (2) Injury of blood vessels: in the experimental group, at 3 months, micro-intimal hyperplasia was observed. Elastic fibers of partial vascular endothelium were reduced. Elastic fiber andmiddle-layer smooth muscle breakage and proliferation were found. At 6 months, above manifestations were more remarkable. In the control group, arteriole film was not thickened, and vessel wal was normal. (3) Formation of microthrombus, in the experimental group, the number of microthrombus was increased at 3 months, and became significant at 6 months. In the control group, the number of microthrombus was not altered. (4) Results indicated that chronic alcohol intake can lead to microvascular endothelial injury in the rat femoral head. Abnormal blood microcirculation was detected in local region, and resulted in avascular necrosis of the femoral head. The degree of necrosis was associated with alcohol intake.

A new method has been established for simultaneous determination of anions and cations in fertilizer sample by multimodal liquid chromatography with direct conductivity detection. An Acclaim Trinity P1 column based on nanopolymer silica hybrid technology with multimodal separation functional groups reversed-phase/anion-exchange/cation-exchange was used for the analysis. The chromatographic conditions were optimized and the effect ion of eluent on retention was discussed. Eight ions ( Li+, NH+4 , K+, HCOO-, NO-2 , Cl-, NO-3 and Br-) were separated and determined simultaneously by using 25 mmol/L CH3 COONa solution containing 50% acetonitrile at pH=5. 0 as mobile phase. The flow rate was 0. 50 mL/min and the temperature was 30 ℃. Under the optimum conditions, the linear ranges of the method were in the range of 0 . 5-200 mg/L for all the ions with correlation coefficient of 0 . 9997-0 . 9999 . Whereas the detection limits (S/N=3) were in the range of 0. 16-1. 72 mg/L and the relative standard deviations (RSD, n=9) were in the range of 1 . 3-2 . 5%. The method was applied to the determination of anions and cations in the fertilizer samples with satisfied results and the recoveries were in the range of 95 . 8%-103 . 8%.
