OBJECTIVEThe aim of work was to evaluate the efficacy of microvascular decompression (MVD) in patients with trigeminal neuralgia (TN) associated with hypertension.

METHODSFive hundred and thirty-eight cases of TN associated with hypertension treated with MVD were retrospectively analyzed, all the cases were treated with MVD in the zone of the ventrolateral medulla oblongata and inspected postoperative blood pressure.

RESULTSAmong 538 cases, 341 cases (63.4%) had cure result, 71 cases (13.2%) had obvious effectiveness, 53 cases (9.8%) had effectiveness, and 73 cases had no effectiveness. Four hundred and eighty-three cases have been followed 1.0 approximately 15.8 years, mean 6.3 years. At the time of their follow-up, 313 cases had cure result, 63 cases had obvious effectiveness, 42 cases had effectiveness and 65 cases had no effectiveness.

CONCLUSIONSIt was pathogenesis of nedulla oblongata by abnormal vascular tab, long-term aching stimulation and emotional stress. It was an effective method to treat TN associated with hypertension with MVD in this zone.

OBJECTIVETo investigate the efficacy of anticoagulation and thrombolysis for deep venous thrombosis via local vein approach and peripheral vein approach to guide clinical treatment.

METHODSThere were 225 patients with deep venous thrombosis admitted from January 2001 to May 2008. The cases were divided into two groups by therapy procedures. The patients in group A were treated by deep femoral vein catheter-directed anticoagulation and thrombolysis, including a total number of 71 patients, with right lower extremity in 20 patients, left lower extremity in 47 patients and bilateral lower extremities in 4 patients. One hundred and fifty-four patients were included in group B with anticoagulation and thrombolysis through peripheral vein, among them right lower extremity in 27 patients, left lower extremity in 121 patients and bilateral lower extremities in 6 patients. The efficacy was evaluated and compared by observing clinical symptoms and measuring of changes in limb circumference.

RESULTSSymptoms were alleviated in all patients in 3 d after the treatment, but the efficacy of group A was better than group B (94.4% vs.69.5%, P < 0.01). The efficacy of group A was also better than group B in 7 days after treatment, but with no significant difference (85.9% vs. 75.3%, P > 0.05). A mean follow-up period was (43 ± 18) months. There was no significant difference in incidence of complication and recurrence between two groups.

CONCLUSIONSThe earlier efficacy of anticoagulation and thrombolysis via femoral vein approach is better than via peripheral vein approach in earlier period of deep venous thrombosis. While peripheral intravenous therapy has also good results after long-term treatment.

Tuberculous aortic aneurysm (TBAA) is an extremely rare clinical event with life-threatening implication. Management for this condition is challenging and its therapeutic option has not been yet established. A few recent reports described endovascular repair rather than open surgery as the method for treatment. Although this remains controversial, endovascular exclusion has been gaining acceptance for some surgeons. We present a case of TBAA who was treated by endovascular stent grafting for a descending thoracic aortic aneurysm with simultaneous anti-tuberculous medication. The outcome was favorable.

BACKGROUNDInflammatory abdominal aortic aneurysms (IAAAs) are rare but distinct clinical entities of atherosclerotic abdominal aortic aneurysms (aAAAs). In this study we report a 20-year single institution experience for IAAA and analyze their clinical features and long term outcome in comparison with aAAA.

METHODSBetween 1988 and 2008, 412 cases of abdominal aortic aneurysms (AAAs) underwent elective surgical operations, 11 (2.7%) of whom were diagnosed as IAAAs and 389 (94.4%) were diagnosed as aAAAs. The former group was matched in a case control fashion to a group of 33 patients with aAAAs having similar characteristics of age, gender, and preoperative risk factors. All available clinical, pathologic, and postoperative variables were retrospectively reviewed, and the two groups were compared.

RESULTSThe two groups did not differ significantly in clinical characteristics and preoperative risk factors, although patients with IAAAs were significantly more symptomatic (100% vs. 42.4%, P = 0.001) and had larger aneurysms on admission ((7.4 +/- 0.7) cm vs. (6.3 +/- 0.9) cm, P = 0.006). In IAAAs, the preoperative erythrocyte sedimentation rate was found to be significantly elevated compared to aAAA group ((44.5 +/- 9.1) mm/h vs. (11.4 +/- 5.4) mm/h, P < 0.05). Surgical morbidity and mortality rates did not differ between the two groups. The operation time for patients with IAAAs was significantly longer than that for patients with aAAAs ((308 +/- 36) minutes vs. (224 +/- 46) minutes, P < 0.05), but the cross-clamp time was similar in both groups ((41.5 +/- 6.2) minutes vs. (41.8 +/- 6.2) minutes, P = 0.92). A five-year survival rate analysis showed no significant difference between the two groups (P = 0.711).

CONCLUSIONSDespite having more symptoms, larger size and longer operation time, patients with IAAA can now be treated with approaches that cause low morbidity and mortality, similar to patients with aAAA. Long term outcome of IAAA patients is of no difference from aAAA patients.

Objective To assess the heritability of serum uric acid in adult,using the classic twin design.Methods Adult Twins were recruited from the Qingdao Twin Registry.Uric acid,height,weight were measured.Zygosity in all the same-sex twin pairs was determined by 16 polymorphic markers.Heritability was assessed by structural equation models,with age,gender and body mass index(BMI) included as covariates.Results In total,687 twin pairs were available for data analyses,including 420 pairs of monozygotic and 267 pairs of dizygotic twins.After logarithm transformed,uric acid in males ( 17.47±1.91 ) was significantly higher than in females ( 15.22±1.70,P＜0.0001 ).After adjustment on age,sex and BMI,intraclass correlations for uric acid were 0.70 for monozygotic twins and 0.40 for dizygotic twins.The sex-limitation AE model,combining additive genetic and unique environmental factors,could produce the best fit for the data.Heritability estimate for uric acid was 70.5% (95% CI:65.9-74.6),with the proportion of unique environmental effects as 29.5%(95%CI:25.4-34.2).Conclusion Additive genetic effects appeared to be the major contributor to the variation of uric acid in this twins sample being studied.

BACKGROUNDTo investigate the correlation of clinical features with pathology in chronic viral hepatitis (CH).

METHODSAnalyses of single factor and multiple factors of serum biochemical indices, imaging examination results, symptoms and signs with degree of pathological lesion of hepatic tissue in 973 cases of CH were conducted. Meanwhile, the hepatic functional index (AAPEA index) was used to investigate the role of serum biochemical indices in diagnosis of CH.

RESULTSIn these patients with CH,the severity of hepatic lesion was closely correlated to symptoms and signs, biochemical indices such as PTA, ALT, TBIL, ALB, A/G, gamma-globulin (gamma-G) by electrophoresis, AST and cholinesterase (CHE) as well as splenic thickness. AST was superior to ALT in reflecting degree of hepatic inflammatory activity. The total mistaken judgment rate of multiple factor analysis was 28.1%. The correlation coefficient of AAPEA index to degrees of hepatic inflammatory activity, fibrosis and pathological grading was 0.559, 0.545 and 0.529, respectively (P<0.000 1)

CONCLUSIONSThe biochemical indices such as PTA, ALT, TBIL, ALB, A/G, gammaG, AST, CHE and the determination of splenic thickness by ultrasonography B could reflect hepatic pathological changes to certain extent. AST was superior to ALT in reflecting degree of hepatic inflammatory activity. Incorrect judgment rate was high in determination of moderate and severe CH by multiple factor analysis. Conformity rate between AAPEA index and pathological diagnosis was better than any of them alone in diagnosing CH.

BACKGROUNDEffect of percutaneous transluminal septal ablation (PTSA) with ethanol injection on electromechanical remodeling of left ventricule still remains unknown. This study was conducted to assess the potential significance of cardiac electromechanical mapping (CEMM) in analyzing the left ventricular remodeling before and immediately after percutaneous transseptal myocardial ablation (PTSMA) in patients with hypertrophic obstructive cardiomyopathy (HOCM).

METHODSEight patients with drug-refractory HOCM and 6 patients with hypertrophic cardiopathy (HM) without increased left ventricular outtract gradien (LVOTG) were enrolled into the present study. CEMM was undergone in patients with HOCM before and immediately after PTSA procedure, and in patients with HM.

RESULTSPTSA was successful in all patients with HOCM, LVOTG significantly decreased from (62.87 +/- 21.16) mmHg to (12.73 +/- 3.05) mmHg immediately after ablation procedure. Value of UVP in septal-base segment in HM group was higher than that in HOCM group [(22.79 +/- 2.34) mV vs (18.54 +/- 1.76) mV]. In patients with HOCM, lateral-middle and -base segments had lowest value of UVP [(15.93 +/- 1.11) mV and (15.83 +/- 1.07) mV] before PTSA. Value of UVP at posterior-middle segment decreased from (23.58 +/- 2.21) mV pre-PTSA to (18.89 +/- 1.91) mV post-procedure, PTSA led to significant increase of UVP at lateral-middle segment. Septal region in patients with HM and septal-middle, septal-base, posterior-base segments in HOCM had lower value of local linear shortening (LLS) among all patients in both HOCM and HM groups. PTSA resulted in significant reduction of LLS in anterior region and at septal-apex segment. Anterior-base and septal-middle segments in patients with HM had lowest value of local active time (LAT), and significantly differentiated from that in patients with HOCM [(-8.57 +/- 0.68) ms vs (-18.61 +/- 1.02) ms, (-6.75 +/- 0.37)ms vs (-21.90 +/- 0.96) ms, respectively]. LAT at septal-middle and -base segments in patients with HOCM was decreased significantly [(-21.90 +/- 0.96) ms vs (-13.80 +/- 1.04) ms, P < 0.002; and (-15.20 +/- 1.06) ms vs (-6.33 +/- 0.52) ms, respectively] immediately after PTSA.

CONCLUSIONSPosterior-lateral and anterior region probably played important roles in electromechanical remodeling. Significant electromechanical remodeling disassociation (uncoupling) was detected in most left ventricular regions, which would be important in differentiating of HOCM from HM, and in predicting the prognosis in patients with HOCM after PTSA procedure.
