Objective To observe the variations of biochemical indicators in serum followed the different contusion on soft tissues and also analyze their significance in forensic practice.Methods The SD rats were selected as experimental animal as well as were randomly divided into four groups: sham control,mild,medium and strong force depending on the height of strike falling in anesthesia state.Sacrificed the rats at the same time point and harvested the blood.Serumal creatine kinase(CK),isoenzyme of creatine kinase(CK-MB),lactate dehydrogenase(LDH),creatinine(Cr),urea nitrogen(UN) ?-hydroxybutyrate dehydrogenase(HBDH) and aspartic acid transferase(AST) were tested.The data were analyzed quantitatively with SPSS 12.0.Results The AST,CK,CK-Mb,HBDH,UN and Cr all increased accompanied with higher scale of strike.The statistics showed that a dramatically difference existed between the overall traumatic groups(including to the mild,medium and strong) and the control.The AST,CK and CK-MB showed significant differences in 3 experimental groups.Meanwhile,the perimeter of the traumatic limbs was a good marker for the power of the strike.Conclusion The contusion not only appeared in the local areas but also cause the myocardial damage in the period of early trauma.

Chronic heart failure is the final stage of various cardiovascular diseases,and mitochondrial energy metabolism disorders have been proved to play an important role in the development of chronic heart failure.TCM believes that heart yin is the material basis of heart yang(qi),and deficiency of heart yang(qi)is the core pathogenesis of chronic heart failure.Based on mitochondrial energy metabolism,this article expounded the scientific connotation of"reinforcing yang from yin"in the treatment of chronic heart failure from the aspects of theoretical connotation,pathogenesis,pathophysiological relationship and modern research.In-depth study at the microscopic level demonstrated that the application of"reinforcing yang from yin"method can effectively improve the reconstruction of heart energy substrate(yin),enhance mitochondrial function,and finally provide energy support(yang),which could offer ideas for theoretical research and clinical prevention and treatment of chronic heart failure.

Objective To compare animal models of chronic heart failure(CHF)prepared by three different protocols,to establish a stable,reliable,and reproducible mouse model of CHF.Methods Twenty-five male C57BL/6J mice were divided randomly into four groups:a blank group,model A group(MA group),model B group(MB group),and model C group(MC group).The model groups adopted different preparation protocols for continuous injection of isoprenaline.The MA group and MB group were dose-decreasing models:MA group:subcutaneous injection of 10 mg/kg on day 1,5 mg/kg on day 2,2.5 mg/(kg·d)on days 3~30,total 30 days;and MB group:subcutaneous injection of 20 mg/kg on day 1,10 mg/kg on day 2,5 mg/(kg·d)on days 3~14,total 14 days.The MC group used a constant dose of intraperitoneal injection of 7.5 mg/(kg·d)for 28 days.The day after the final injection,the survival and model-formation rates for each group of mice were calculated.Cardiac function was measured by cardiac ultrasound and serum levels of N-terminal pro B-type natriuretic peptide,interleukin-6,and tumor necrosis factor-α were measured.Results CHF was successfully induced in all the model groups after all injections at the end of the fourth week.However,comprehensive test result showed that the MC model was the most stable.Conclusions An isoprenaline-induced mouse model of CHF using constant intraperitoneal injection of 7.5 mg/(kg·d)for 28 days may be the most suitable model for subsequent research on traditional Chinese medicine.

Chronic renal failure (CRF) is generally characterized by micro-inflammatory state, which can aggravate the CRF process in severe cases, leading to the deterioration of renal function, malnutrition, anemia and other complications. Therefore, it is of great significance to improve the micro-inflammatory state of CRF. "Deficiency of Qi and stagnation" is the basic pathogenesis of the micro-inflammatory state of CRF, which runs through the whole process of the disease and affects the formation and outcome of CRF in different forms. Traditional Chinese medicine (TCM) has unique advantages in improving the micro-inflammatory state and enhancing the immunity of the body due to its advantages of syndrome differentiation and treatment, strengthening the righteousness and eliminating pathogenic factors. Therefore, the author systematically sorted out the relationship between micro-inflammatory state and CRF, understanding of micro-inflammatory state of CRF and its prevention and treatment of TCM by referring to relevant literature, based on the theory of "deficiency of Qi and stagnation", and proposed that spleen and kidney failure (deficiency of Qi) is the origin of micro-inflammatory state of CRF, and blood stasis and poisonous evil (stagnation) is the target of its onset. Deficiency of Qi and stagnation adhered to each other, acted as cause and effect, and developed in a spiral manner throughout the development of the disease. TCM has the effects of nourishing the spleen and kidney, removing blood stasis and turbidity. By down-regulating C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α) and other micro-inflammatory indicators, it can eliminate the pathological wastes derived from spleen and kidney deficiency, reduce the micro-inflammatory state, restore the balance of Yin and Yang in the body to achieve the purpose of eliminating pathogens and protecting renal function, providing guidance for the clinical treatment of CRF.

ObjectiveTo observe the difference in the efficacy of three kinds of traditional Chinese medicine (TCM) injections on rat model of heart failure induced by transverse aortic constriction (TAC), explore the TCM syndrome of the model based on the theory of correspondence of prescription and syndrome, and reveal the biological basis of prescription-syndrome from the perspective of metabolism. MethodRats were treated with TAC for modeling and were divided into Shenmai injection group (6.0 mL·kg-1), model group, Danhong injection group (6.0 mL·kg-1), Shenfu injection group (6.0 mL·kg-1) and trimetazidine group (10 mg·kg-1), and sham operation group was set up as control. After drug intervention for 15 days, echocardiography, serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and myocardial histopathological staining were performed for each group, so as to compare the efficacy to select the effective injection. Colorimetry was used to detect the serum glucolipid metabolism after the intervention of the effective injection, and ultra high performance liquid chromatography-mass spectrometry was used to observe the metabolites and related metabolic pathways in myocardial tissue. ResultCompared with the sham operation group, the left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (FS) in the model group decreased (P<0.01), while the left ventricular end-diastolic diameter (LVIDd), left ventricular internal diameter at end-systole (LVIDs) and NT-proBNP level increased (P<0.01). Compared with model group, LVEF and FS increased (P<0.01), LVIDd, LVIDs and NT-proBNP level decreased (P<0.05, P<0.01) in Danhong injection group, NT-proBNP level in Shenfu injection group decreased (P<0.05), LVIDd and NT-proBNP level increased (P<0.05, P<0.01) in Shenmai injection group, in trimetazidine group, LVEF and FS increased (P<0.01), while LVIDs and NT-proBNP level decreased (P<0.05, P<0.01). Serum glucose, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol levels in Danhong injection group and trimetazidine group were adjusted by callbacks (P<0.01, P<0.05). There were the callback of 9 myocardial metabolites in Danhong injection group, including glycine, serine and threonine metabolism, glyoxylate and dicarboxylate metabolism, glycerol phospholipid metabolism. There were the callback of 10 myocardial metabolites in trimetazidine group, including glycerol phospholipid metabolism. ConclusionThe efficacy of Danhong injection on heart failure model induced by TAC is significant and superior to Shenfu injection and Shenmai injection, suggesting that the model is closely related to heart-blood stasis. The biological mechanism of Danhong injection interfering with the model involves regulating the metabolic disorder of lipid, glucose, amino acid and butyric acid.
