Retrograde subintimal angioplasty for treatment of occlusive diseases in the long segment of the infrapopliteal artery / 南方医科大学学报

<p><b>OBJECTIVE</b>To assess the clinical efficacy of retrograde puncture subintimal angioplasty (SIA) for treatment of occlusive diseases in the long segment of the infrapopliteal artery.</p><p><b>METHODS</b>The clinical data of 50 patients with occlusive diseases in the long segment of the infrapopliteal artery were retrospectively analyzed. The patients were divided into control group (n=25) and study group (n=25) and received antegrade SIA and retrograde puncture SIA with long balloon after the failed antegrade SIA, respectively. The ankle brachial index (ABI) and the temperature of the infrapopliteal skin before and after the operation were compared between the two groups.</p><p><b>RESULTS</b>The technical success rate was 100% in the 50 patients, who showed obviously improved ischemic symptoms without serious complications. The ABI of the study group increased from 0.31 ± 0.12 before the treatment to 0.47 ± 0.09 at 24 h, 0.56 ± 0.06 at 1 week, 0.63 ± 0.07 at 3 months, 0.58 ± 0.06 at 6 months, and 0.49 ± 0.03 at 12 months after the treatment, and the skin temperature increased from 28.13 ± 2.45 before the operation to 33.87 ± 1.24, 34.16 ± 0.44, 34.19 ± 0.25, 32.45 ± 0.25, and 31.05 ± 0.21 at the corresponding time points after the treatment, respectively, showing significant improvements after the operation (P<0.05). ABI, skin temperature and the patency rate were similar between the two groups at each of the postoperative time points (P>0.05).</p><p><b>CONCLUSION</b>Retrograde puncture SIA is safe and effective for treatment of arteriosclerosis obliterans in the infrapopliteal arteries with a high clinical success rate and a low complication rate after the failure of antegrade SIA.</p>

The Identification of Uygur Medicine Dracocephalum Moldavica L. and Its Sibling by ITS2 Sequence / 世界科学技术-中医药现代化

Objective: To establish the DNA barcode identification method of Uygur Medicine Dracocephalum mol-davica L. Methods: D. moldavica L. and its ten sibling species of twenty five samples was amplified by ITS2 se-quence, after sequencing and comparing the intraspecific and interspecific variation, we using K2P and NJ meth-ods to analysis the their relationship, then compare the secondary structure. Results: D. Moldavica (KF041160, KF041163, KF041168, KF041169) from Xinjiang without variation in intraspecies, but there are two 2 variation sites in D. moldavica (AY506659) from GenBank. By NJ method, D. moldavica can be distinguished with their sibling species. Also, D. nutans L., D. bipinnatum Rupr. and D. integrifolium Bge. can be distinguished with oth-er sibling species. Conclusion: ITS2 barcode sequence was able to identify D. moldavica and its sibling species, which provides an effective way for the molecular identification of Uygur Medicine D. moldavica.

Influence of gender and psychosocial parameters on the quality of life in patients with irritable bowel syndrome / 中国基层医药

ObjectiveTo investigate the influence of gender and psychosocial parameters on the quality of life in patients with irritable bowel syndrome(IBS). MethodsOut-patients from Jan to Oct 2008 in the Department of Gastroenterology at the First Affiliated Hospital of Nanjing Medical University were enrolled. Based on Rome teria IBS was diagnosed. Interviewed by a GI physician with questionnaire of demographic data,Zung self-rating anxiety and depression scale(SAS/SDS) and IBS-specific quality of life(IBS-QOL) questionnaire. Results452 patients were diagnosed as IBS according to Rome Ⅲ criteria. IBS was more common in female. In male, anxiety and depression scales were significantly increased( t =7. 191、6. 459 ,P ＜ 0. 01 ) and the scale of IBS-QOL was significantly decreased ( t =9.119, P ＜ 0.01 ) in female IBS patients. In IBS patients, IBS-QOL scales were negatively associated with the anxiety and depression scales(P ＜0. 01 ). ConclusionThese results suggest that there were gender differences in psychological status and quality of life in IBS patients,and difference psychological status based on gender should influence the quality of life of patients with IBS.
