Objective To investigate the spatial distribution and clustering areas of Budd-Chiari syndrome in Heze City,Shandong Province,and to provide epidemiological information for further exploring the etiology and related risk factors of the disease.Methods Detailed residential addresses of 342 cases of patients (residents of Heze City) with diaphragm type Budd-Chiari syndrome diagnosed between 1995 and 2004 in Heze Municipal Hospital,Heze Shan County Central Hospital,Affiliated Hospital of Xuzhou Medical College,Shandong Provincial Hospital and Beijing Xuanwu Hospital were collected.Geographic information system (GIS) was used as a platform for data management and display.The nearest neighbor index,Ripley's K(d) function,Ripley's L(d) function and the nearest neighbor clustering method were applied to detect the spatial characters of Budd-Chiari syndrome in Heze City,Shandong Province.Crimestat 3.0 was used for spatial analysis.Results The nearest neighbor distance analysis showed that the nearest neighbor index was 0.6767 (Z =-11.4387,P ＜ 0.01).That was an aggregation at the first-order spatial scale.Within the study area,the first clustering radius of Budd-Chiari syndrome was 6.66 km,and the first clustering strength was 5.40; the average radius of the strongest clustering area was 126.61 km,and the clustering strength was 12.52,while the biggest clustering radius was larger than 222 km.After corrected by population,the gathering strength was slightly higher than that before the correction.Ten first-order hot spots were formed,and 95％ confidence interval aggregation number was 7,which meant the results were statistically significant(P ＜ 0.05),main clustering areas are in Mudan District,Shan County and Juancheng.One secondorder hot spot was gathered based on the first-order hot spot.Conclusions Spatial distribution of Budd-Chiari syndrome in Heze City,Shandong Province has showed spatial aggregation and heterogeneity.This study has a great epidemiological significance for further exploring the cause of Budd-Chiari syndrome.

Objective To discuss the key points of endovascular therapy for complex subclavian artery occlusive diseases. Methods During the period from January 2012 to December 2013, a total of 92 patients with complex subclavian artery occlusive disease were admitted to Xuanwu Hospital of Capital Medical University, Beijing, China. The clinical data were retrospectively analyzed. The features of the lesions, the success rate of endovascular therapy, the use of combined approaches, the relief of symptoms after treatment, etc. were evaluated. Results The complex subclavian artery occlusive diseases could be divided into three types. Type Ⅰ: long segment of the left subclavian artery was occluded; type Ⅱ: ostial stenosis or occlusion of the right subclavian artery; and type Ⅲ: subclavian artery stenosis or occlusion was associated with the ostial disorder of the vertebral artery, or the opening of vertebral artery was affected by the subclavian artery stenosis or occlusion. The technical success rate was 82.6%. Combination use of femoral artery and brachial artery approach was employed in 27.2% of patients, which had improved the technical success rate. After the treatment the symptom improvement rate was 81.6%. Conclusion Upper limb artery approach can improve the re-canalization rate of left subclavian artery with long segment occlusion, and can ensure the accurate positioning of stent at the site of right subclavian artery opening. During the procedure of endovascular intervention for subclavian artery occlusion disease, attention should be paid to the protection of the vertebral artery.

AIMTo develop a rapid and feasible method based on micellar electrokinetic capillary chromatography (MECC) for the simultaneous determination of antiepileptic drugs (AEDs)--phenytoin (PHT), phenobarbital (PB), carbamazepine (CBZ), primidone (PRM) and clonazepam (CZP) in human plasma.

METHODSSeveral factors that impact the separation of AEDs with MECC were investigated, such as concentration of sodium dodecyl sulfate (SDS), buffer compositions, pH, organic modifier, internal diameter and temperature, and an optimized MECC running condition was obtained the running buffer consisted of 8 mmol x L(-1) phosphate, 3 mmol x L(-1) sodium tetraborate, and 50 mmol x L(-1) sodium dodecylsulfate (SDS) (pH 8.0), containing acetonitrile (ACN) (18%) as organic modifier. Detection at 210 nm, run at 25 kV at 30 degrees C in a untreated fused silica capillary (50/45.5 cm length, 50 microm ID).

RESULTSThe reproducibility of both migration time and relative peak area with MECC analysis were appropriate for the intra- and inter-assay coefficients. The evaluated drugs concentration intervals of PRM 1.0-40.0 microg x mL(-1), PB 1.0-60.0 microg x mL(-1), PHT 1.0-40.0 microg x mL(-1), CBZ 1.0-40.0 microg x mL(-1), CZP 0.2-8.0 microg x mL(-1) were linear with correlation coefficients higher than 0.999 1, and coefficients of the variation of the points of the calibration curve lower than 10%. The recoveries of AEDs varied from 80.0% to 100.0%, depending on the drug, with coefficients of the variation lower than 10.0%.

CONCLUSIONThe MECC technique is showed to be rapid, simple, efficient and low cost when applied to monitoring therapeutic drugs in patient treated with a combination of PHT and other AEDs such as hepatic enzyme-inducing agents.

It's difficult to identify Aucklandiae Radix and Vladimiriae Radix because of their similar composition. In this paper, UPLC method was used to establish their UPLC fingerprint to identify them with the mobile of acetonitrile -0. 05% phosphoric acid water solution by gradient elution at the detection wavelength of 238 nm. Clustering analysis and principal components analysis showed that Vladimiriae Radix was significantly different from Aucklandiae Radix. Eight common peaks and twelve common peaks were defined respectively in Aucklandiae Radix and Vladimiriae Radix herbs by fingerprint analysis. Six of them were identified as syringoside, chlorogenic acid, isochlorogenic acid A, isochlorogenic acid B, costunolide and dehydrocostuslactone by comparing with standard references. There are four peaks in all of Vladimiriae Radix samples and in none of Aucklandiae Radix samples. So UPLC fingerprint can be used to identify these two herbs.

OBJECTIVETo summarize the experience of urethral reconstruction using circular fasciocutaneous flap for the treatment of complex anterior urethral strictures.

METHODThe circular fasciocutaneous flap was harvested from the distal penile shaft or foreskin. Then the circular configuration was converted into longitudinal strip of skin which was rotated to ventral side to repair the exposured urethral strictures using the ventral onlay method. The surveillance protocol after urethroplasty was urination observation, regularly uroflowmetry and urethrography examination.

RESULTSFrom Nov. 2006 to Oct. 2012, 15 cases were treated. The mean age was 45 years (20-76 years) and mean follow-up period was 18 months(3 months-3 years). Stricture was caused by chronic urethritis in 4 cases, long-term urethral catheterization in 3 cases, transurethral perfusion chem other aphy in 3 cases, transurethral prostatectomy in 3 cases and hypospadias after surgery in 2 patients. The mean stricture length was 7.0 cm (3.5-12.0 cm). The overall success rate was 80.0% (12/15). Recurrence stenosis was noted in 2 cases and diverticulum formation in 1 case.

CONCLUSIONSThe penile circular fasciocutaneous flap can be used for anterior urethral stricture in nearly any length. The flap has the characteristics of hairless, adequate mobile and length, well-vascularized pedicle and easy to harvest. The onlay reconstruction provides excellent cosmetic results, less trauma, higher success rate. Therefore it should be one of the preferred techniques for complex anterior urethral stricture repair.
