The present analysis explores female partners＇ treatment preference for erectile dysfunction in Chinese Men. This was a phase 4, randomized, open-label, multicenter, crossover study in Chinese men with erectile dysfunction who were na＇fve to phosphodiesterase type 5 inhibitor treatments. Eligible patients were randomized to sequential 20-mg tadalafil/100-mg sildenafil or lO0-mg sildenafil/20-mg tadalafil for 8 weeks each. Of 418 patients, female partners of 64 patients agreed to enter the study; of 64 patients who entered the study with female partners, 63 were randomized, and 62 completed the study. Baseline demographics and disease characteristics were comparable between treatment groups. Significantly more couples preferred tadalafil compared with sildenafil overall （75.4% vs 24.6%; P〈 0.001）, and irrespective of erectile dysfunction severity at baseline （P 〈 0.005）. Significant improvements in sexual quality of life scores were reported at endpoint （Visit 8） in male patients and female partners in both tadalafil and sildenafil treatment groups （P 〈 0.001）. Significantly higher mean changes from baseline were observed for male patients in the tadalafil group compared with the sildenafil group for the erectile function （P = 0.013） and overall satisfaction （P = 0.019） International Index for Erectile Function domains and the spontaneity domain （P〈 0.001） of the Psychological and Interpersonal Relationship Scale. No major safety concerns were reported during the study. Though both treatments were effective, safe, and tolerable, more couples preferred tadalafil compared with sildenafil.展开更多

However, the ideal dose of intrathecal bupivacaine has not been quantified for cesarean delivery for severe preeclamptic patients. This study aimed to determine the ED50 and ED95 of intrathecal bupivacaine for severely preeclamptic patients undergoing elective cesarean delivery. Methods： Two hundred severely preeclamptic patients are undergoing elective cesarean delivery under combined spinal-epidural anesthesia enrolled in this randomized, double-blinded, dose-ranging study. Patients received 4 rag, 6 mg, 8 mg, or 10 mg intrathecal hyperbaric bupivacaine with 2.5 μg sufentanil. Successful spinal anesthesia was defined as a T6 sensory level achieved within 10 minutes after intrathecal drug administration and/or no epidural supplement was required during the cesarean section. The ED50 and ED95 were calculated with a logistic regression model. Results： ED90 and ED95 ofintrathecal bupivacaine for successful spinal anesthesia were 5.67 mg （95% confidence interval [C/]： 5.20-6.10 mg） and 8.82 mg （95% CI： 8.14-9.87 mg） respectively. The incidence of hypotension in Group 8 mg and Group 10 mg was higher than that in Group 4 mg and Group 6 mg （P 〈 0.05）. The sensory block was significantly different among groups 10 minutes after intrathecal injection （P 〈 0.05）. The use of lidocaine in Group 4 mg was higher than that in other groups （P 〈 0.05）. The use of phenylephrine in Group 8 mg and Group 10 mg was higher than that in the other two groups （P 〈 0.05）. The lowest systolic blood pressure before the infant delivery of Group 8 mg and Group 10 mg was lower than the other two groups （P 〈 0.05）. The satisfaction of muscle relaxation in Group 4 mg was lower than other groups （P 〈 0.05）. There was no significant difference in patients＇ satisfaction and the newborns＇ Apgar score and the blood gas analysis of umbilical artery serum （P 〉 0.05）. Conclusion： Our study showed that the EDs0 and ED~ of intrathecal bupivacaine for severely preeclamptic patients undergoing elective cesarean delivery were 5.67 mg and 8.82 mg, respectively. In addition, decreasing the dose of intrathecal bupivacaine could reduce the incidence of maternal hypotension.展开更多

Recent study results indicate that men with ED in China who were naive to phosphodiesterase inhibitor type 5 （PDE5） therapy prefer tadalafil 20-mg （on-demand） versus sildenafil 100-mg （on-demand）. Differences in psychosocial outcomes may help to explain treatment preference in favor of tadalafih This open-label, randomized, crossover study compared psychosocial outcomes and drug attribute choices between tadalafil and sildenafil in Chinese men with ED na＇（ve to PDE5 inhibitor therapy. Eligible patients were randomized to sequential 20-mg tadalafU/lOO-mg sildenafil （n = 190） or 100-mg sildenafil/20-mg tadalafil （n = 193） for 8 weeks each and were asked which treatment they preferred to take for the 8-week extension phase. Psychosocial outcomes were assessed using the Psychological and Interpersonal Relationship Scale （PAIRS）, Drug Attributes Questionnaire （DRAQ）, and Sexual Life Quality Questionnaire （SLQQ）. When taking tadalafil versus sildenafil, men had a higher mean endpoint score on the PAIRS Spontaneity Domain （tadalafil = 2.86 vs sildenafil = 2.72; P 〈 0.001）, and a lower mean endpoint score on the Time Concerns Domain （tadalafil = 2.41 vs sildenafil = 2.55; P 〈 0.001）. A numerical increase in the Sexual Self-Confidence Domain was observed when taking tadalafil versus sildenafil （tadalafil -- 2.76 vs sildenafil = 2.72; P= 0.102）. The most frequently chosen drug attributes explaining treatment preference were able to get an erection long after having drug, and ability to get an erection every time. SLQQ results were comparable between treatment groups. These psychosocial outcomes may explain why more Chinese men preferred tadalafil versus sildenafil for the treatment of ED in this clinical trial.展开更多

文摘To the Editor:Simple hepatic cyst is a common reason for consultation with gastroenterologists and hepatologists.Although most patients have a benign course,some suffer from serious complications,such as intracystic infection,hemorrhage,and even rupture,or symptoms caused by severe oppression of the surrounding tissues and organs.Understanding the prevalence of,and characteristics of,and factors associated with simple hepatic cysts is helpful for better treatment of symptomatic patients.The reported prevalence of the disease varies widely,ranging from 2.5%to 18.0%,and most of them were based on hospital surveys.[1,2,3,4]As an asymptomatic disease in most cases,simple hepatic cysts are usually discovered incidentally on abdominal imaging.Therefore,surveys based on hospital populations cannot represent true prevalence.Furthermore,due to the absence of healthy controls,surveys with hospital populations have been unable to identify associated factors for simple hepatic cysts.[1,2,3,4].
