RESUMO
Objective To explore the safety and efficacy of resistance training (RT) and aerobic exercise (AT) for low back pain during pregnancy. Methods From June to October, 2015, 34 women gestated 20-23 weeks with low back pain accepted resistance training and aero-bic gymnastics exercises twice a week for 12 weeks. They were measured with blood pressure and body mass index (BMI), and assessed with Visual Analogue Scale (VAS) of pain, Self-rating Anxiety Scale (SAS) and Oswestry Disability Index (ODI) before and after treatment. They were investigated the injury and symptoms with questionnaire. Results No musculoskeletal injuries and groin bleeding occurred. Symptoms, such as dizziness and pelvic pain were infrequent (1.5%). The BMI increased (t=-5.791, P<0.001) and the blood pressure did not obviously change (t=1.441, P=0.159). The muscle strength (t=-5.081, P<0.001) and endurance (t=-5.019, P<0.001) increased, and the scores of VAS (t=-5.179, P<0.001), ODI (t=-5.206, P<0.001) and SAS (t=-5.024, P<0.001) significantly improved after treatment. Con-clusion The resistance training combined with aerobic training program during pregnancy is safe and efficacious for pregnant women with low back pain.
RESUMO
Objective To evaluate the safety,effectiveness and clinical factors of re-intervention of transjugular intrahepatic porto-systemic shunt (TIPS).Methods A retrospective study of safety and longterm outcomes of TIPS was made in 771 patients from August 1994 to August 2010.The 625 patients had follow-up data.The patients who received TIPS once,twice,and more than twice were divided into group 1,group 2 and group 3,respectively.Clinical symptoms,survival rate and restenosis rate of each group were analyzed.Clinical influencing factors of re-intervention effect were discussed.Results The success rate of first intervention was 98.2％ (757/771),the death rate was 0.7％ (5/757) and severe complication rate was 2.5％ (19/757).The success rate of re-intervention was 98.7％ (457/463),no death and severe complications occurred.The restenosis rate in group 3 decreased significantly than group 1 ( x2 =7.908,P ＜0.05 ) in the first year of TIPS.The restenosis rates in group 2 and group 3 were lower than group 1 from 2 to 5 years of TIPS ( x2 values were 27.046,25.724,37.002 and 19.046,respectively,P ＜ 0.05 ). The survival rate in group 3 was higher than group 1 (x2 =9.114,P＜0.05)and group 2 was higher than group 1 ( x2 =4.929,P ＜ 0.05 ) in the first year of TIPS,while there was no statistical difference between group 2 and group 3 ( x2 =2.678,P ＞ 0.05).The patients in group 2 and group 3 also had higher survival rates than group 1 from 2 to 5 years of TIPS (x2 value were 41.314,26.920,13.692 and 6.713,respectively,P ＜ 0.05 ).19.4％ (79/406)of patients who received re-intervention had symptom recurrence and shunt stenosis or occlusion. 11.6％ (47/406) of patients had symptom recurrence with portal hypertension signs,62.8％ (255/406) had shunt stenosis or occlusion with portal hypertension signs.Conclusions Restenosis or occlusion of TIPS,symptom recurrence and portal hypertension signs were important factors for re-intervention.Re-intervention of TIPS was safe and effective,and could improve the survival rate of patients with TIPS.
RESUMO
Object To study the chemical constituents of the underground part of Glehnia littoralis Fr. Schimidt ex Miq. Methods Eight compounds were isolated from EtOAc-soluble fraction of ethanol extract of G. littoralis by repeated chromatography over silica gel. Their structures were determined on the basis of their spectral data. Results They were identified as falcalindiol (Ⅰ), (8E)-1, 8-heptadecadiene-4, 6-diyne-3, 10-diol (Ⅱ), bergapten (Ⅲ), cnidilin (Ⅳ), xanthotoxin (Ⅴ), salicylic acid (Ⅵ), vanillic acid (Ⅶ), ferulic acid (Ⅷ). Conclusion Compounds Ⅱ and Ⅵ-Ⅷ were isolated from this plant for the first time.
