3 cases of intracranial aneurismal residue following clipping at Viet Duc Hospital were studied. The causes of this condition were anatomical and technical. It is necessary to identified prior surgery the cause of hemorrhage, to limit the disruption of aneurism, to expose entirely the neck of aneurism before the setting of clip and to explore throughly the place of clip- Anterigraphy or systematic Xray control should be made for checking the results

This association had been reported for long time with a frequency of 2.7-23% of cases of intracerebral arteriovenous connection. This association increases the risk of cerebral meningo hemorrhage. 3 cases of cerebral meningo hemorrhage associated with intracerebral arteriovenous connective malformation were studied retrospectively and treated at Viet Duc Hospital from January 1999 to January 2004. The presence of aneurysm in cerebral arteriovenous connection was an important predictive factor for the hemorrhage possibility, leading to cerebral hemorrhage

Meningocerebral haemorrhage due to the rupture of malformation of cerebral arterio venous fistula is neurosurgical emegency that requires the radical management to prevent from relapsed haemorrhage. Currently in Vietnam, the operation for malformation removal is an unique technique. The restrespective study on 16 cases suffered the rupture of malformation of cerebral arterio venous fistula in Vietduc during 1999-2000 showed the encourage results. 81.3% of malformations were radically removed, 18.7% of malformation were partial removed and experienced ligation of artery the outcomes: good (81%) and no death

A retrospective study on 14 case of ruptured cerebral cranial carotid aneurysm operated in Viet Duc Hospital during 1998 - 2000 has shown that the clinical outcome and method of operation found well in 78.6% of patients. The time for operation was usually late (often 2-3 weeks of bleeding).

Objective To study prognostic indicators in T1a renal cell carcinoma(RCC) from perspective of pathology .Methods Three hundred and thirty - eight patients with single sex renal cell carcinoma were collected from January 1996 to January 2013 in our hospital ,we retrospectively analyzed their clinical pathological features and the relationship between the disease progression , and explored the factors that affect the recurrence and distant metastasis .Results 11 cases(3 .3% ) patients were identified as a tumor recurrence ,9 of them had a clear metastatic lesions .Multi factor analysis results showed that the high tumor grade (level 3 and level 4) was an independent risk factor for tumor recurrence (hazard the wire :13 .0 ,95% CI :3 .90 - 43 .00 ,P < 0 .01) ;while age ,sex ,tumor size ,histological manifestations ,infringement of microcirculation and the operation factors such as boundary condi‐tion had no obvious correlation with tumor recurrence .Five years relapse free survival in patients with tumor grade high was 67 .8% ,compared with 96 .8% in the lower graded .Conclusion Fuhrman nuclear grading is a reliability index to judge the progno‐sis of T1a renal cell carcinoma postoperative recurrence and metastasis ,and higher class T1a phase need strengthening postoperative follow up and monitoring .

Objective:To establish a dissolution determination method for nisoldipine tablets. Methods: The detection was car-ried out according to the second method described in ChP VolumeⅡappendix XC. The medium was 600 ml hydrochloric acid solution (0. 1 mol·L-1 ) containing 0. 05% SDS, the rotation speed was 75 r·min-1 , and the UV detection wavelength was at 238nm. Re-sults:The linear range of nisoldipine was 4-14 μg·ml-1(r=0. 999 9),and the average recovery was 100. 5%(RSD=1. 1%, n=9). Conclusion:The method is simple, accurate and reliable, and can be used in the dissolution determination of nisoldipine tablets.

Objective To investigate effect of Danhong injection combined with atorvastatin treatment of patients with unstable anginapectoris.Methods Ninety patients with unstable anginapectoris from Mar.2010to Dec.2013 in the First People's Hospital were selected and randomly grouped as control group(n=40) and atorvastatin-Danhong injection group(n =50).All patients in two groups were treated with routine therapy,and patients in the atorvastatin-Danhong injection group were also treated with atorvastatin at dose of 20 mg per day for 15 days and Danhong injection at dose of 30 ml in 250 ml physiological saline per day for 15 days.The level of high-sensitivity C-reactive protdn(hs-CRP) in serum and the haemodynamics of two groups during before and post-treatment were measured and analyzed.Results The effective rate of atorvastatin-Danhong injection group was 84.0％ (42/50),higher than that in control group (70.0％ (28/40),x2 =5.738,P =0.039).The level of hs-CRP in two groups at after treatment were (7.6±2.1) and (3.6±1.7) mg/L,lower than those at pretreatment((1 8.6±4.7) mg/L,(19.2±4.2) mg/L),and the differences were significant (t =8.644,7.848;P =0.004,0.007).Compared with control group after treatment,the level of hs-CRP in atorvastatin-Danhong injection group decreased rapidly (t =6.384,P =0.009).Compared with pre-treatment,the low cut blood viscosity(LCBV),high shearrate blood viscosity(HSBV),plasma viscosity and red cell assembling index in two groups were decreased remarkably(P＜0.05).Compared with control group at post-treatment,the LCBV,HSBV,plasma viscosity and red cell assembling index in atorvastatin-Danhong injection group were significantly declined (t=5.142,4.672,5.738,5.354;P＜0.05).Conclusion Danhong injection combine with atorvastatin improves the haemodynamics in patients with unstable anginapectoris and induce the inflammatory reaction,and it has the better the effects.

To upgrade the original hospital network with 10 gigabit network technology to promote the devel-opment of PACS. The present situation of some hospital network and requirements of PACS were analyzed, and three schemes were put forward based on 10 gigabit network. The advantages and disadvantages of the schemes were compared, and the third scheme was selected based on considerations on the practice and budget. The hospital network was enhanced in reliability, safety and extendibility. Network upgrade with 10 gigabit network tech-nology provides a high-bandwidth, high-stability and high-reliability data transmission platform.

Objective To investigate the changing patterns of serum IL-6, IL-10, IL-23 and osteopontin in patients with smear-negative pulmonary tuberculosis before and after treatment and their clinical implication.Methods A total of 43 patients with smear-negative pulmonary tuberculosis and 40 healthy controls were included in this study. Enzyme-linked immunosorbent assay (ELISA) was conducted to measure the levels of serum IL-6, IL-10, IL-23 and osteopontin in healthy individuals and patients before and after anti-tuberculosis treatment for 2, 4 and 6 months.Results The levels of serum IL-6, IL-10, IL-23 and osteopontin in patients with smear-negative pulmonary tuberculosis were signiifcantly higher than those in control group (P<0.05). After treatment for two months, the levels of serum IL-6, IL-10, IL-23 and osteopontin signiifcantly decreased in patients with smear-negative pulmonary tuberculosis (P<0.05). The serum IL-10 and osteopontin were nearly restored to normal levels in patients after four months treatment and there were no signiifcant difference compared with those in control group (P>0.05). The levels of serum IL-6 and IL-23 gradually decreased after treatment, and restored to normal at six months. There was no signiifcant difference compared with those in control group (P>0.05). Conclusions Serum IL-6, IL-10, IL-23 and osteopontin levels in patients with smear-negative pulmonary tuberculosis can be used as sensitive indicators for assessment of tuberculosis disease activity and therapeutic effect of anti-tuberculosis drugs.

The distribution of factor H of serum phenotypes were studied using the ultra-thinpolyacrylamide gel isoelectric focusing (PAGIEF) followed by Immunoblotting technique in 203Chinese Han population in Liaoning area. The gene frequencies were as follows: HFA0. 4828,HFB0.5172. The observed numbers of the phenotype were in agreement with the expected numbers underthe Hardy-Weinberg equilibrium. The gene frequencies among Chinese and other population werecompared.
