1.The X-Ray Anatomy and Clinical Significance of the Left Spermatic Vein
Journal of Interventional Radiology 1994;0(02):-
The anatomic analysis of spermatic veins were carried out by 30 cases of spermatic venography and disection on 20 spermatic veins of 10 cadavers. After close obser- vation, 6 basic types of left internal spermatic veins were obtained on roentgenologic anatomy: 0 type (normal valvular type) 6.7%, 1 type 46.7%, 2 type (Y type) 26.7%. 3 type (H type) 13.3%, 4 type (main stem bifurcation type)3.3%, 5,type (inverse F type) 3.3%. 0-1 types were considered as normal 53.3%, 2-5 types were of normal varients 46.7%. The choice of embolization treatment for internal spermatie varicosities should be varied with different types.
2.Effects of urokinase thrombolysis on matrix metalloproteinase-9,blood-brain barrier permeability and intracerebral hemorrhage in a rat model of middle cerebral artery thromboembolism
International Journal of Cerebrovascular Diseases 2009;17(9):668-672
Objective To observe the effects of the expressions of matrix metalloproteinase-9(MMP-9),intracerebral hemorrhage volumae and blood-brain barrier permeability after embolic cerebral ischemia and thrombolysis with urokinase(UK)and to investigate the relationship between MMP-9 and blood-brain barrier permeability and intracerebral hemorrhage after thrombolysis. Methods A rat model of middle cerebral artery occlusion was established by intracarotid injection of autologous blood clots.UK was given intravenously at 6 hours after ischemia. After 24 hours. the expressions of MMP-9 in brain tissue, blood-brain barrier permeability, cerebral infarct volume, and intracerebral hemorrhage volume were detected by the immunohistochemical method, Evans blue extravasation method, TTC staining method, and spectrophotometric method,respectively. Results The expressions of MMP-9 in a cerebral ischemic group were significantly higher than those in a sham-operation group(P<0.01),and in the UK group they were significantly higher than those in the cerebral ischemic group (P<0.01).The Evens blue content in the cerebral ischemic group was 5774.00±1659.70 ng/g, which was significantly higher than 643.33±151.34 ng/g in the sham-operation group (P<0.01),and in the UK group was 6283.83±1099.28 ng/g, there was a tendency higher than in the cerebral ischemic group. The intracerebral hemorrhage volumes in the UK and cerebral ischemic groups were 3.16±8.84μl(median±quartile)and 0.00±1.48μl, respectively, and the inciderices of intracerebral hemorrhage were 25.00%%and 4.17%.respectively.Conclusions UK thrombolysis may upregulate the expressions of MMP-9.and its expressions are associated with the increased blood-brain barrier permeability and intracerebral hemorrhage after thrombolysis.
3.Ca~(2+) sparks in cardiac myocytes
Chinese Pharmacological Bulletin 1987;0(01):-
In cardiac myocytes, Ca 2+ sparks origining fr om a single RyR or a few RyRs are triggered by a single L-type Ca 2+ channel or occur spontaneously. Ca 2+ sparks constitute the elementary local Ca 2+ release events from the SR. Ca 2+ sparks occur at Z-lines and rando mly distribute at different locations, the characteristics of the kinetics are r egulated by many factors. In addition, I Ca.T, Na+/Ca 2+ exchang e, I Ca(TTX) and IP 3 are other putative sources of Ca 2+ that tr igger SR Ca 2+ release.

OBJECTIVE:To study the improving effects of argatroban on the brain damage of model rats with cerebral hemor-rhage. METHODS:50 SD rats were randomly divided into normal control group(equivalent normal saline),model group(equiva-lent normal saline),argatroban high,medium and low dose groups (0.75,1.5,3 mg/kg). All groups,except for normal control group,were reproduced models with cerebral hemorrhage,and the rats in each group were treated by corresponding drugs after 30 min,ip,once a day. The rats were executed after continuous administration for 3 days. The data was detected,including the con-tents of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),activity of cysteine-containing aspartic protease 3(Caspase-3), expressions of Bcl-2,Bax,matrix metalloproteinase-2(MMP-2)and MMP-9,and the phosphorylations of nuclear factor κB(NF-κB) p65 and IκBα. RESULTS:Compared with the normal control group,the contents of TNF-α and IL-1β,the activity of Cas-pase-3,the expressions of MMP-2,MMP-9 and Bax proteins were increased;the expression of Bcl-2 was decreased;and phos-phorylations of NF- κB p65 and IκBα in model group were increased,with significant differences(P<0.01). Compared with the model group,the contents of TNF-α and IL-1β,the activity of Caspase-3,the expressions of MMP-2,MMP-9 and Bax were de-creased;the expression of Bcl-2 was increased;and phosphorylations of NF-κB p65 and IκBα in argatroban low,medium and high dose groups were decreased,with significant differences (P<0.01 or P<0.05). And it was positively correlated with the dose. CONCLUSIONS:Argatroban has dose-dependent inhibition effects on the inflammatory cytokine secretion and apoptosis of brain tissue of model rats with brain hemorrhage,and the mechanism may be related to NF-κB signaling pathway.

Hydrolysate of Meretrix meretrix soft tissue (HMST ) (20, 10g/kg ,po.for 14d ) could markedly inhibit the increase of serum total cholesterol(TC)and triglyceride(TG),enhance the content of high density lipoprotein cholesterol(HLD-C) ;reduced cholesterol(Ch)of the liver(for 28d)in hyperlipimic quail ;and it could also reduce whole blood viscosity in normal and hyperlipemic quail (for 21d).In addition.it could suppress the platelet aggregation induced by ADP in rabbits in vitro. The results show that HMST obviously decreased blood lipid and whole blood viscosity .inhibited platelet aggregation.

Objective To explore liver protective effects of the stems and leaves and roots of Scutellariae Radix from different areas of Gansu Province;To discuss differences in liver protection of the stems and leaves and roots of Scutellariae Radix. Methods All Kunming mice were randomly divided into 11 groups:normal group, model group, positive control group, Scutellariae Radix root groups and Scutellariae Radix stem-leaf groups of Longxi, Minxian, Weiyuan, Zhangxian. The mice received gavage with relevant medicine once a day for 7 days. 2 hours after the last medication, the mice were given peritoneal injection with 0.1%CCl4 and olive oil to establish the models with liver injury. Hepatic index, the activity of serum ALT and AST, the levels of T-AOC in the liver tissue were calculated in 18 hours after establishing the models. Results Compared with the model group, hepatic index, the activity of serum ALT and AST in the mice of Scutellariae Radix root groups from difference producing areas decreased significantly (P<0.05);the levels of T-AOC in the liver tissue was raised notably (P<0.05). Compared with stem-leaf groups from the same producing area, hepatic index, the activity of ALT and AST in the mice of Scutellariae Radix root groups were remarkably lower than these of Scutellariae Radix stem-leaf groups (P<0.05);the levels of T-AOC in the liver tissue was evidently higher than that of Scutellariae Radix stem-leaf group (P<0.05). Conclusion Scutellariae Radix root water decoction can prevent and protect CCl4-induced acute liver injury to a certain degree, while Scutellariae Radix stem-leaf water decoction shows no significant protective effect on acute liver injury.
