BACKGROUND:After knee joint replacement, patients are often treated with Rivaroxaban and Enoxaparin Sodium for postoperative anticoagulation, avoiding the formation of deep vein thrombosis in lower limbs. OBJECTIVE:To explore the application effects of different anticoagulant drugs in patients with knee joint replacement. METHODS:Ninety patients underwent knee joint replacement in Xiangya Second Hospital of Central South University from July 2011 to July 2014, were randomly divided into two groups, with 45 patients in each group. The experimental group was treated with Rivaroxaban, while the control group was treated with Enoxaparin. RESULTS AND CONCLUSION:Postoperative drainage volume, total blood transfusion, bleeding index, quantity of blood platelet, activated partial thromboplastin time, thrombin reduction time, whole blood viscosity, plasma viscosity, D-dimer coagulation index, HSS score at postoperative 2 weeks, average ecchymosis area, average thigh circumference, and average leg circumference were significantly better in the experimental group, than in the control group (P<0.05). The incidence of deep vein thrombosis of lower limbs in the experimental group was lower than that in the control group (P<0.05). Experimental findings indicate that, both Rivaroxaban and Enoxaparin can exert anticoagulation effect during the knee joint replacement, and Rivaroxaban is better.

AIM: To investigate the effect of mfn2 on mitochondrial function in steatosis hepatocytes. METHODS: Plasmid pEGFP-mfn2 was transfected into hepatocyte strain L02 by Lipofectamine 2000 in vitro, then the steatosis model of hepatocytes was establish by oleic acid induction. RT-PCR was used to evaluate mRNA expression and Western blotting was use to detect the protein expression. ATP level was determined by firefly luciferase bioluminescent. ROS production was measured by fluorescence probe DCFH-DA. Chondrosome transmembrane potential of L02 was observed by labeling of JC-1 and FCM. RESULTS: The stable expression of ectogenesis mitofusin2 in L02 cells was confirmed by RT-PCR and Western blotting. In the model of oleic acids induced lipid formation, Mfn2 obviously inhibited the descent of chondrosome transmembrane potential and ATP level, and increased ROS production in L02 cells. CONCLUSION: Up-regulated expression of mfn2 attenuates mitochondria dysfunction caused by oleic acids induced lipid formation.

ObjectiveTo investigate the cause,diagnosis and treatment measures of neonatal pneumothorax.MethodsThe clinical data of 98 cases with neonatal pneumothorax in our hospital from Mar 2005 to Mar 2010 were reviewed retrospectively.ResultsThere were 27 premature neonates and 71 full-term neonates in the 98 cases.Ten cases were spontaneous pneumothorax and 88 cases were non spontaneous pneumothorax.After the treatnent of primary disease,pleural aspiration,chest drainage and mechanical ventilation,88 cases were cured,8 cases were improved and 2 cases died.ConclusionNeonatal pneumothorax is related with cesarean section,improper use of endotracheal intubation,meconium aspiration,premature hyaline membrane disease using pulmonary surfactant and ventilator therapy.Most pneumothorax is due to lung disease.The prevention of preterm birth and asphyxia can reduce the incidence of neonatal pneumothorax.

G mutation of SLC26A4, the parents and the second child were carriers of the same mutation, while the fetus had a wild-type form. Conclusion It is feasible to identify deafness related genes by screening for GJB2 and SLC26A4 mutation, thus providing correct prenatal diagnosis and avoiding deaf delivery of baby.

To evaluate the efficacy of Tuina and Chinese patent drug Shuxuetong injection in preventing patients undergoing total knee arthroplasty from deep venous thrombosis and in functional rehabilitation.

This study on determination of leukemia-specific chromosomal abnormalities and their relationship with prognosis of childhood acute leukemia (AL) had an important significance for childhood acute leukemia. In recent years, the efficacy of treatment of childhood AL has been greatly improved, but relapse is still a main factor affecting prognosis. Treatment based on the risk stratification by cytogenetic abnormalities can improve the prognosis and survival rate. In the past 3 decades, the genetic techniques have developed rapidly and many new genetic abnormalities have been found. This review highlights the main chromosomal and genomic abnormalities of 3 common childhood AL, including B-cell precursor acute lymphoblastic leukemia (BCP-ALL), T-cell acute lymphoblastic leukemia (T-ALL) and acute myeloid leukemia (AML).

Objective Using STI and WMSI to evaluate the change of the heart sarcomere local systolic function which suffered from coronary heart disease (CHD), to evaluate the improvement of ischemic heart sarcomere local systolic function after PCI. Methods There are 40 CHD patients after PCI called the treatment group and 40 healthy persons called the control group. Echocardiogram was used to evaluate the change of ventricular wall motion score in the treatment group which was before and 1 week after PCI , compared with the control group. STI is used to get the SLs, GSL and SrLe of the left ventricle six walls in basal segment,middle segmentand apical segment systole. Results The ventricular wall motion index of the left ventricular myocardium obviously rose in CHD patients which was after PCI, compared with the control group (P < 0.05). And it obviously reduced in CHD patients after PCI, compared with CHD patients before PCI(P < 0.05). The results of SLs,GSL and SrLe are reduced in myocardial ischemia segment of CHD patients before PCI,compared with the control group (P < 0.05). But they are significantly improved in the the treatment group 1 week after PCI, compared to which is before PCI(P < 0.05). Conclusion STI and WMS can be used to evaluate the abnormal of regional and global function of myocardium which is caused to coronary artery stenosis the effect of PCI. The left ventricular motion function of CHD is decreased, but the left ventricle regional systolic function of hypokinetic segments in patients with CHD after PCI is significantly increased.

As an important neurotransmitter, adenosine displays its functions by acting on the adenosine receptors. Recent studies have shown that the distribution, expression and balance among subtypes of adenosine receptors are closely related with cognitive activities, and changes of adenosine receptors play key roles in neurodegenerative disorders including Alzheimer's disease. It has been pointed out that prolonged activation of adenosine receptors by high level adenosine may lead to the disturbance of balance among adenosine receptor subtypes. This imbalance mainly performed as increased expression of A2a receptor and decreased expression of A1 receptor, and enhancement of the excitatory signals mediated by A2a receptor and weakened inhibitory signals mediated by A1 receptor. Changes of these two subtypes of adenosine receptors may lead to a lot of disorders of neurological activities which developed into dysfunction of cognition to the end. These findings imply that the potential of maintaining the balance among adenosine receptors on the treatment of AD would facilitate both the revealing of the mechanism and the cure of AD.

OBJECTIVETo study the effects of combined use of total alkaloids (TA) of Uncaria rhynchophylla (UR) and Coryadlis ambailis migo (CAM) on cerebral ischemia/reperfusion injury in rats.

METHODSRat model of middle cerebral artery ischemia/reperfusion was established, the changes of neurological state was scored before and after treatment with the two kinds of TA, single or combined, and the changes of cerebral infarcted volume, cerebral water content, activities of NOS and SOD and content of MDA in rats' brain were estimated as well.

RESULTSAfter being treated with the combination of both TA, the average neurological score, cerebral infracted volume, cerebral water content, activity of NOS and content of MDA in the model rats significantly decreased, and the activity of SOD was significantly increased (all P < 0.05). The effect of combined use of the two TA was higher than that of use TA of UR or CAM alone (P <0.05). Moreover, the central nervous system inhibitory effect induced by combined TA was significantly weaker than that of UR.

CONCLUSIONCombined use of TA of UR and CAM may facilitate the protection against cerebral ischemia/reperfusion damage, the action mechanism might be relevant to reducing the lipid peroxidation injury of brain cells through inhibiting the NOS activity and increasing the SOD activity.
