Objective To observe the clinical efficacy of hydroxyfasudil in senile heart failure caused by coronary heart disease (CHD). Methods 110 Patients with heart failure caused by CHD were randomly divided into two groups. 55 patients in control group were given conventional treatment, whereas the remaining patients were assigned into hydroxyfasudil group in the base of conventional treatment. After 6 months, we observed and compared the changes in cardiac function of the two groups. Results The effective rate of treatment group was 96.36% and the control group was 85.45%. There was statistical difference between the two groups (P < 0.05). Then we compared the degree of improvement of left ventricular diastolic function using ultrasonic cardiogram and Tei index. Left ventricular ejection fraction of treatment group improved significantly but biochemical indicators of two groups had no statistical difference. Conclusion In patients with heart failure caused by CHD, supplementation of hydroxyfasudil based on conventional therapy could improve diastolic function , potentiate left ventricular remodeling and enhance the life quality. Furthermore, it′s more sensitivity and reasonable to assess cardiac function using Tei index as compared with using ultrasonic cardiogram.

Objective The aim of this study was to explore the establishment method of an animal model of irritable bowel syndrome ( IBS) and the evaluation of this animal model.Methods 30 adult SD rats were randomly divided into two groups: acetic acid irritation and bondage stress group ( n=10 ) , bondage stress group ( n =10 ) , and normal control group ( n=10 ) .The rats of the intervention group received an intra-colonic infusion of 0.4% acetic acid irritation combined with bondage stress to establish an animal model of IBS.The colonic sensitivity of the intervention group rats was assessed by stool test and colorectal distension ( CRD) test.Hydrochloric acid toluidine blue staining was used to observe the number degranulation phenomenon of mast cells in the ileocecum.Results On the 7th day, the number of soft feces was 8 and loose stool was 4 in the model group, significantly higher than that in the bondage stress group(0 and 0) (P<0.05),and normal control group (1 and 0) (P<0.05).On the 10th day, when the AWR=2, the average rectal distension volume was 1.2 mL, significantly lower than that in the bondage stress group(1.37mL) (P <0.05),also significantly lower than in the normal control group (1.49 mL) (P<0.05), and when the AWR=4, the average rectal distension volume was 1.49 mL, significantly lower than that in the bondage stress group(1.74mL) (P<0.05),and the normal control group (1.77 mL) (P<0.05).These results indicated that the visceral sensitivity of the model group was significantly higher than that in the bondage stress group and normal control group.Histological analysis showed that the rats of all groups had no obvious inflammatory changes.Conclusions Chronic bondage stress combined with intra-colonic infusion of 0.4%acetic acid irritation can be used to increase the visceral sensitivity and amount and degranulation of mast cells in the intestinal tissue in rats.This established rat model shows pathogenetic changes resembling the pathogenesis of human irritable bowel syndrome, and provides a useful animal model for further studies of the pathogenesis of this disease.

BACKGROUND:There is no unified method for treatment of intertrochanteric fracture. Previous dynamic hip screw fixation has some shortcomings, and is gradual y replaced by intramedul ary nail fixation. interTan is a compression interlocking intramedul ary nail designed by Smith Nephew in USA according the characteristics of intertrochanteric fracture. Unique design of pressurized screw thread has control able linear pressure. Moreover, it has the stability of Z-effect anti-rotation.
OBJECTIVE:To analyze the clinical therapeutic effects and superiority of interTan compression interlocking intramedul ary nail for intertrochanteric fracture.
METHODS:A total of 60 patients with intertrochanteric fracture undergoing interTan compression interlocking intramedul ary nail in the Department of Orthopedics, Beijing Chaoyang Emergency Rescue Center from January 2011 to December 2012 were enrol ed in the experimental group. A total of 60 patients with intertrochanteric fractures receiving dynamic hip screw fixation in the Department of Orthopedics, Beijing Chaoyang Emergency Rescue Center from January 2009 to December 2010 were enrol ed in the control group.
RESULTS AND CONCLUSION:Peri-operative bleeding volume, postoperative ambulation time, numerical rating scale score, radiographic healing time and weight-bearing time in the experimental group were lower than those of control group. At 3, 6 months and 1 year after fixation, Harris score and hospital for special surgery knee score were higher in the experimental group than in the control group. These data indicated that compared with dynamic hip screw, interTan compression interlocking intramedul ary nail has unique stability due to its design. Internal fixation can reduce operation trauma, promote fracture healing and improve joint function, and exhibit good clinical therapeutic effects for intertrochanteric fractures.

BACKGROUND:Mesenchymal stem cells are a kind of adult stem cells with the potentials of self-replicating and multi-directional differentiation. Under certain conditions, the cells can develop into bone, cartilage and other types of cells. Granulocyte colony-stimulating factors can promote regeneration of mesenchymal stem cells.
OBJECTIVE:To observe the osteogenic induction effect of granulocyte colony-stimulating factors by animal experiment, and provide a better treatment method for clinical treatment of bone defect.
METHODS:Forty New Zealand rabbits were randomly divided into treatment group and model group. Al animals were removed 2 cm length of the right radial bone and the surrounding periosteum, and then implanted with demineralized bone matrix into the defect. The treatment group was subcutaneously injected with granulocyte colony-stimulating factor 30μg/kg per day, the injection was started at preoperative 3 days and given for 7 continuous days. In control group, the same dose of physiological saline was injected.
RESULTS AND CONCLUSION:In the treatment group, the number of mesenchymal stem cells, the quantity and quality of bone formation at bone defects were better than those in the model group. The experimental findings indicate that granulocyte colony-stimulating factor can obviously increase the number of mesenchymal stem cells and promote bone formation at the area of bone defect, which can contribute to early repair of bone defects.

BACKGROUND:Spine infection models are rarely reported in the literature. There are fewer reports on the imaging and histological observations of the animal model of spinal infection.
OBJECTIVE:To develop a canine model of pyogenic spinal infection.
METHODS:Twelve Chinese dogs were adopted in the study. The dogs were in the right arm recumbent. The surgery was conducted by retroperitoneal approach to expose T12/L1 intervertebral space. The intervertebral discs that exposed the intervertebral space were partial y removed, and the end plate of the adjacent two vertebrae was deliberately curetted out. Suspension with different concentrations of Staphylococcus aureus and sodium morrhuate were injected into the dog intervertebral space. The aim of removal of partial intervertebral discs and destruction of endplate was to make the vertebral body bone better in contact with the bacteria. The same operation was conducted in L5/6 clearance of the animal spine. At 14 days after surgery, animals were sacrificed. The infected intervertebral disc and adjacent vertebral bodies were taken out. Bacterial contents of specimens were quantitatively determined. During sacrificing, partial liver tissues and blood samples were col ected for bacterial culture. The occurrence of systemic infection was observed.
RESULTS AND CONCLUSION:(1) Spondylodiscitis of the lumbar spinal column was consistently produced in 90%(9/10) the sites chal enged with 102 colony-forming units (CFU) Staphylococcus aureus. Liver biopsy and blood culture did not show any signs of systematic infections. (2) Two out of four animals implanted the suspension with a concentration higher than 103 CFUs died within 3 days post-implantation. (3) These results suggested that a new canine model of pyogenic spinal infection was developed. This model could be used to test the efficacy of different anti-infection strategies.
