The impact of erectile dysfunction is distressing to both males and their female partners, but less attention has been paid to identify female partners＇ preferred treatment and sexual quality of life outcomes. 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.

Sildenafil and tadalafil are efficacious and well tolerated in Chinese men with erectile dysfunction （ED）. 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.

The activation of the sirtuin1(SIRT1)/nuclear factor erythroid 2-related factor 2(Nrf2)/heme oxygenase 1(HO-1) pathway has been shown to mitigate oxidative stress-induced apoptosis and mitochondrial damage by reducing reactive oxygen species(ROS) levels. Clinical trials have demonstrated that Zhongfeng Xingnao Liquid(ZFXN) ameliorates post-stroke cognitive impairment(PSCI). However, the underlying mechanism, particularly whether it involves protecting mitochondria and inhibiting apoptosis through the SIRT1/Nrf2/HO-1 pathway, remains unclear. This study employed an oxygen-glucose deprivation(OGD) cell model using SHSY5Y cells and induced PSCI in rats through modified bilateral carotid artery ligation(2VO).The effects of ZFXN on learning and memory, neuroprotective activity, mitochondrial function, oxidative stress, and the SIRT1/Nrf2/HO-1 pathway were evaluated both in vivo and in vitro. Results indicated that ZFXN significantly increased the B-cell lymphoma 2(Bcl2)/Bcl2-associated X(Bax) ratio, reduced terminal deoxynucleotidyl transferase-mediated d UTP nickend-labeling(TUNEL)+ cells, and markedly improved cognition, synaptic plasticity, and neuronal function in the hippocampus and cortex. Furthermore, ZFXN exhibited potent antioxidant activity, evidenced by decreased ROS and malondialdehyde(MDA) content and increased superoxide dismutase(SOD), catalase(CAT), and glutathione(GSH) levels. ZFXN also demonstrated considerable enhancement of mitochondrial membrane potential(MMP), Tom 20 fluorescence intensity, adenosine triphosphate(ATP) and energy charge(EC) levels, and mitochondrial complex Ⅰ and Ⅲ activity, thereby inhibiting mitochondrial damage. Additionally,ZFXN significantly increased SIRT1 activity and elevated SIRT1, nuclear Nrf2, and HO-1 ***, these effects were substantially counteracted when SIRT1 was suppressed by the inhibitor EX-527 in vitro. In conclusion, ZFXN alleviates PSCI by activating the SIRT1/Nrf2/HO-1 pathway and preventing mitochond

Background： Spinal anesthesia was considered as a reasonable anesthetic option in severe preeclampsia when cesarean delivery is indicated, and there is no indwelling epidural catheter or contraindication to spinal anesthesia. 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 ne
