Objective To summarize the technique and managements of complications in endovascular embolization on intracranial aneurysm with Guglielmi detachable coils(GDC),and to evaluate the effect of the treatment.Methods One hundred and thirty six cases with Aneurizym were treated using GDC to embolize the aneurismal sac via femoral artery approach.Results One hundred and thirty six aneurysms were cured.Of them 132 cases recovered clinically,4 patients died.The mortality was 2.9%. The sac of 123 aneurysms were embolizied at 100%,8 cases with 95% embolization,5 with 90% embolization.3 aneurysms reptured during the embolization,cerebral vasospasm happened in 7 eases. microcoil escaped in 2 case.Three recurring cases were cured after second GDC embolization.The technique-related complications occured in 13 cases.No re-bleeding occurred during the 6 to 54-month follow-up.Conclusion Endovascular embolization of intracranial aneurysm with coils is a safe and effective treatment for intracranial aneurysm.Advances in Techniques and treating the complications correctly would decrease the complications and improve future outcomes.

Objective To explore the methods of early etiological diagnosis and principles of endovascular embolization in Hunt-Hess Ⅳ—Ⅴ grade subarachnoid hemorrhage(SAH),and to evaluate the therapeutic efficacy.Methods Thirty-one patients underwent imaging examinations such as CT and DSA to make the early diagnosis of SAH.Meanwhile,Guglielmi detachable microcoil(GDC)was used to applying aneurysmal intracapsular embolization in the ruptured aneurysms,and efficient symptomatic treatment was adopted early postoperatively.The results were tested by ?~2 test.Results All 31 cases were diagnosed early and operated successfully.Among them,the aneurysm lumen was 100% occluded in 26 cases,95% occluded in 3 cases;90% occluded in 2 cases.There were 5 cases complicating with cerebral vasospasm.One case recurrent was cured with secondary complementary GDC embolization.Nine cases(29.0%)had permanent sequelae associated with SAH.According to the Glasgow prognosis score, the therapeutic efficacy was as following:6 patients were in grade Ⅰ,9 in grade Ⅱ,4 in grade m,2 in grade Ⅳ,and 10 in grade Ⅴ;10 patients died,and the morality rate was 32.3%.None of them exhibited re-bleeding with follow-up period of 3 to 68 months postoperatively.Morality rates were significantly different between the group with aneurysmal diameter of 11—25 mm and the group of 5—10 mm(?~2=6.60,P

OBJECTIVETo evaluate the feasibility and efficacy of a new method of endoscopic esophageal variceal ligation combined with partial splenic embolization (EVL-PSE) for the patients with portal hypertension.

METHODSFrom May 1999 to February 2003, sixty-eight patients with portal hypertension underwent EVL-PSE, and hemodynamics of the portal trunk (PT), the left gastric vein and azygos vein, including maximum velocity, flow volume, vein diameter, were assessed using color ultrasound Doppler.

RESULTSThe esophageal varices and hypersplenism were greatly ameliorated after operation in patients who had undergone EVL-PSE. Postoperative portal trunk flow volume and velocity were significantly reduced (P < 0.05), and flow volume of the left gastric vein as well as the azygos vein were also reduced after operation. During 2 - 24-month follow-up, no recurrent bleeding was found.

CONCLUSIONSEVL-PSE is less traumatic with less complications, and results in marked eradication of esophageal varices, it can be carried out safely in the clinical treatment for patients with portal hypertension.

AIMTo study the chemical constituents of the stems and leaves of Aconitum coreanum (Lèvl.) Rapaics.

METHODSThe constituents of Aconitum coreanum were isolated by using various kinds of modern chromatographic methods. The new alkaloid was identified on the basis of spectral analysis.

RESULTSTwo compounds were isolated and identified as: 13-dehydro-1beta-acetyl-2alpha,6beta-dihydroxyhetisine (I) and Guanfu base G (II).

CONCLUSIONCompound I is a new alkaloid.

OBJECTIVETo discuss the early diagnostic methods and therapeutic principles of aneurysmal subarachnoid hemorrhage (SAH), and evaluate the therapeutic efficacy objectively.

METHODSUsing neuro-imaging examinations combined with case history and clinical symptoms to make the early diagnosis of 96 case with aneurysmal SAH, and Guglielmi detachable microcoil (GDC) was utilized for early intracapsular embolization in the ruptured aneurysms. Efficient symptomatic treatment was done early after operation.

RESULTSAll of 96 cases were early diagnosed and successfully embolized; Among them, the aneurysmal lumen was 100% occluded in 83 cases, 95% in 8 cases, 90% in 5 cases. There were 3 cases complicating with aneurysms rupture during operation, 5 cases with cerebral vasospasm. One case was affected by microcoil terminal escape after operation, 3 recurrent cases were all cured with secondary GDC embolization. There were 9 complications associated with embolization techniques and 13 cases (13.5%) occurring permanent sequelae associated with SAH. According to the Glasgow prognosis score, 77 patients got grade I, 7 grade II, 6 grade III, 3 grade IV, and 3 grade V. The mortality rate was 3.1%.

CONCLUSIONSTo make early etiological diagnosis of the SAH patients, using GDC to embolize the aneurysms, and earlier efficient symptomatic treatment are important methods to improve the curative rate and reduce the mortality rate.

OBJECTIVETo characterize genotypic resistance within HBV RT region in chronic hepatitis B (CHB) patients with nucleos(t)ide analogue (NA) treatment.

METHODSSerum samples of 229 CHB patients with NA treatment were obtained. Full-length HBV RT sequences were amplified, sequenced and analyzed, on the following NA resistant (NAr) mutations belonging to different NAr pathways.

RESULTSAmong 229 HBV isolates, 14.41% (33/229) and 85.59% (196/229) were genotype B and C, respectively; and the patients with HBV genotype C may be more susceptible to develope resistant mutations than patients with HBV genotype B(chi2 = 2.95, P < 0.05). NAr mutations were detected in 63 CHB patients. Mutations were not found at rtI169, rtT184, rtA194 or rtS202. RtM204 mutations were detected at the highest frequency among 63 mutants (40/63, 63.49%) and found to display 11 combination mutation patterns, in which rtM204I were associated with rtL80I/V and rtL180M, and rtM204V were associated with rtL1l80M, respectively. Conclusions There are complicated mutation patterns in the HBV RT region for chronic hepatitis B (CHB) patients with nucleos(t)ide analogue (NA) treatment. RtM204V/I mutation was the highest.

The aim of this study is to investigate the effects of Gynostemma pentaphyllum dried with two different methods(air drying and heating) on inflammation in acute lung injury(ALI) mice in vivo and in vitro. Lipopolysaccharide(LPS) was sprayed into the airway of wild type C57BL/6J male mice to establish the model, and the drug was injected into the tail vein 24 h after modeling. Lung function, lung tissue wet/dry weight(W/D) ratio, the total protein concentration, interleukin 6(IL-6), IL-1β, and tumor necrosis factor-α(TNF-α) in the bronchoalveolar lavage fluid(BALF), and pathological changes of the lung tissue were used to evaluate the effects of different gypenosides on ALI mice. The results showed that total gypenosides(YGGPs) and the gypenosides substituted with one or two glycosyl(GPs_(1-2)) in the air-dried sample improved the lung function, significantly lowered the levels of IL-1β and TNF-α in BALF, and alleviated the lung inflammation of ALI mice. Moreover, GPs_(1-2) had a more significant effect on inhibiting NO release in RAW264.7 cells. This study showed that different drying methods affected the anti-inflammatory activity of G. pentaphyllum, and the rare saponins in the air-dried sample without heating had better anti-inflammatory activity.
