Objective:To study the effect of diammonium glycyrrhizinate (DG) on left ventricular function impairment during myocardial ischemia－reperfusion in rats.　Methods:The left ventricular was cannulated through right common carotid artery on the myocardial ischemia－reperfusion injury model. The left ventricler function was assessed before and 10 minutes after the administration of DG, immediate and 20 minutes after initiation of ischemia, immediate and 30, 60 minutes after reperfusion, by measuring the left ventricular systolic pressure (LVSP), left ventricular end diastolic pressure (LVEDP), ＋dp*dtmax and －dp*dtmax. 　Results:Compared with the baseline, all measurements of LVSP, ＋dp*dtmax and －dp*dtmax decreased (P＜0.05,P＜0.01), while LVEDP increased (P＜0.01) after administration of DG. As the time of ischemia－reperfusion lasting, LVSP, dp*dtmax and －dp*dtmax generally decreased progressively, while LVEDP generally increased progressively. 20 minutes after the initiation of ischemia and immediate, 30 and 60 minutes following reperfusion, LVSP, ＋dp*dtmax and －dp*dtmax in the DG group were significantly higher than those in IR group (P＜0.01), LVEDP significantly lower than that in IR group (P＜0.01) at the same time. 　Conclusion:DG can protect left ventricular function against myocardial ischemia－reperfusion injury in rats.

Objective To research a new algorithm to get the relative pose parameters of spacecraft during the final approach phase of spacecraft rendezvous and docking(RVD).Methods The method was based on the shape of five non-coplanar points and the model of the pinhole,and the conception of 3D reconstruction was employed.For the shape of the mark was known,the 3-D shape of the cross-mark was reconstructed based on the single visual system,and the closed-form algorithm for relative pose parameters of spacecraft was given.Results The algorithm had been validated by the mathematical simulation,and the precise results of the relative pose parameters were calculated.Conclusion The simulation results show that the algorithm is rather simple and with relative accuracy.Furthermore it is meets exact the need in real time.

Objective To evaluate the relationship between hypertension and recurrence of stroke,and to search for the risk factors.Methods The study was done from Dec.2000 to Jun.2002 at Tongji Hospital.The study consisted of 300 hospitalised patients,of which computerized tomography scan proved 100 cases of haemorrhagic stroke and 200 cases of ischemic stroke,and an age and sex matched control per case.The controls were selected from healthy people.We observed difference between stroke and control people in the results of one-year follow-up.Results The recurrence rate of stroke was 10.34% in stroke patients,which was significantly higher than the rate in controls(0.34%)(P

Objective To explore the effect of fuzhengyangyingtang (FZYYT) on bone marrow proliferation in aplastic anemia (AA) mice. Methods AA mice models were set up according to Yaojun descriptive method, and then were randomly divided into FZYYT group, CsA group, FZYYT+CsA group, and AA group, each group containing 10 animals. 10 healthy mice served as control. The former three groups were fed with FZYYT, CsA and FZYYT+CsA, respectively, and the last two groups were fed with normal saline. After fed 10 days the changes in hemoglobin(Hb), platelet, BMNC and bone marrow hematopoiesis tissue volume were determined. Resutls Hb, platelet, BMNC and bone marrow hematopoiesis tissue volume obviously increased in groups FZYYT and CsA compared with AA group, and were the highest in group FZYYT+CsA. Conclusion The results indicated that FZYYT was effective in the treatment of AA.

BACKGROUND: Anterior cruciate ligament injury accompanied by unstable rotation is a hotspot in sports medicine. Further understanding of the anatomy and biomechanics of the anterolateral ligament can play a guiding significance for the recovery of knee joint rotational stability.
OBJECTIVE:To systematicaly review current literature on the anterolateral ligament of the knee and to understand the incidence, anatomy, morphology and histology of the anterolateral ligament as wel as mechanism of anterolateral ligament injury.
METHODS: The first author searched the PubMed, Medline, CNKI, Wanfang, VIP databases for articles specificaly addressing the anterolateral ligament. Data extraction related to the incidence, anatomy, morphometry, biomechanics, and histology of the anterolateral ligament and its relation to the “Segond” fracture was performed. The retrieve time ranged from 1878 to 2015. Totaly 362 literatures were retrieved, including 342 articles in English and 20 in Chinese. According to inclusive and exclusive criteria, 42 articles were included in result analysis.
RESULTS AND CONCLUSION:The occurrence rate of the anterolateral ligament ranges from 83% to 100%, and this range occurs because of smal discrepancies in the definition of the bony insertions of the anterolateral ligament. The anterolateral ligament originates anterior and distal to the femoral attachment of the lateral colateral ligament. It spans the joint in an oblique fashion and inserts between the fibular head and Gerdy tubercle of the tibia. Exact anatomic and morphometric descriptions vary in the literature, and there are discrepancies regarding the anterolateral ligament attachment to the capsule and lateral meniscus. The anterolaterial ligament is a contributor to the stability of tibial internal rotation, and histologicaly, it exhibits paralel, crimped fibers consistent with a ligamentous microstructure. The footprint of the anterolateral ligament has been shown to be at the exact location of the Segond fracture. The anterolateral ligament is a distinct ligamentous structure at the anterolateral plane of the knee, and it is likely involved in the control of excessive tibial internal rotation that can cause the Segond fracture.

Objective To observe the effects of diammonium glycyrrhizinate (DG) on arrhythmia induced by acute myocardial ischemia-reperfusion injury.Methods Electrocardiogram of lead Ⅱwas examined on the myocardial ischemia-reperfusion model,which was induced by the 10 min of ligation of left descending coronary artery and then 30 min of reperfusion in rats.Myocardial malondialdehyde (MDA) content,superoxide dismutase (SOD) activity and adenosine triphosphatase (ATPase),and serum lactate dehydrogenase (LDH) and creatine phosphokinase (CK) levels were measured.Results As compared with the model,DG significantly reduced the incidence of ventricular arrhythmia and its score (P

Objective To investigate the efficiency of ultrasound microbubble-mediated HGF gene transfer on liver fibrosis in rats. Methods The eukaryotic expression vector pMD18-T/HGF was constructed. The rats were randomly divided into 5 groups: normal group, model group, low dose group,middle dose group and high dose group. The rat liver fibrosis were induced. At day 14 after treatment, the rats were sacrificed, the ALT lever were evaluated, pathological evaluation of liver fibrosis were made,immunohistochemical evaluation of HGF protein expressions were observed, HGF mRNA expression were detected by RT-PCR. Results Liver 1function after the treatment showed that the treatment groups were better than model group ( P ＜ 0. 05). The difference between low dose group and normal group showed significant difference ( P ＜0.05), and the difference between middle/high dose groups and normal group showed no significant ( P ＞0. 05). Pathological results showed that the treatment groups could reduce liver fibrosis;treatment groups had the positive HGF expression by immunohistochemistry and the expression level increased with the increasement of the treatment dose ( P ＜0.05). RT-PCR showed HGF mRNA expression in the treatment groups were higher than in model group ( P ＜0.05). Conclusions Ultrasound microbubbles which carrying HGF can inhibit the process of hepatic fibrosis.
