Objective To study and evaluate the feasibility and clinical effects of the treatment of premature ejaculation with modified Masters-Johnson sensate focus exercise.Methods 100 male outpatients with premature ejaculation were divided randomly into two equal groups randomly.The experiment group was treated with the modified Masters-Johnson sensate focus exercise and oral sertraline 50 mg/day for 8 weeks.The control group was given oral sertraline 50 mg/day for 8 weeks.The scores were evaluated with CIPE-5 and compared between the groups before and after the treatment and after the flown-up for 6 moths.Results After treatment,the score of CIPE-5 were better in experiment group than that in control group (P＜0.01).The effective rate 92％ (46/50) in experiment group was significantly higher than that in control group 68％ (34/50) (P＜0.01).The relapse cases (6 cases) were significantly lower than that in the control group (22 cases) (P＜0.01).Conclusions The method of Masters-Johnson sensate focus exercise for treatment of premature ejaculation has a good curative effect,and low recurrence rate,which is worth the clinical promotion.

Objective To study the clinical efficacy of computer-assisted stereotactic brain transplantation of human retinal pigment epithelium (hRPE) cells into the patients with Parkinson disease (PD). Methods Under the guidance of computed X-ray tomography and magnetic resonance imaging image mergence, 4 × 106 hRPE cells were transplanted into the putamen and ventriculus laterlis of 17 cases of PD by stereotactic surgery. The transplantation sites were contralateral to the side of main symptoms and signs. The curative efficacy were observed at the 7th day, 1st month, and 3rd month after the transplantation. Results The contralateral symptoms were ameliorated continuously after the transplantation. Three months after the surgery, the total effective rate of cell transplantation was 88. 2 %, and 82. 4 % of the cases got significant improvement. The cases that got ipsilateral improvement soon after the surgery gave a total effective rate as high as 88. 2 % at the 3rd month during follow-up period, and 64. 7% among these cases improved significantly. Only a minority of cases had transient dizziness and hemiparesis, but the duration was short. Conclusion The therapy, computer-assisted stereotactic transplantation of hRPE ceils in the treatment of PD, is safe and efficient.

AIM: To explore the role of plasma endothelin (ET) in patients with acute cerebral infarction (ACI) and its change after nimodipine treatment.METHODS:Sixty-six patients with ACI were randomly divided into 2 groups according to blood pressure:hypertension ACI group 35 patients［M 20,F 15;age (65±　s　11) a］ and pure ACI group 31 patients［M 17,F 14; age (62±10) a］.Plasma ET was measured by radioimmunoassay and compared with 27 healthy individuals.Among them,42 patients（hypertension ACI group 25 patients，pure ACI group 17 patients） with ACI were given nimodipine 4 mg, iv,gtt, qd, for 2 wk and measured ET again.　RESULTS:Plasma ET in 2 groups were (144±42) ng*L-1 and (72±35) ng*L-1 respectively, and that were (94±55) ng*L-1 and (60±37) ng*L-1 respectively after treatment with nimodipine, but was still higher than that in healthy individuals (P<0.01).　CONCLUSION: The level of plasma ET was associated with blood pressure and the severity of disease. ET is closely related with ACI. Nimodipine reduces the plasma ET while nerve function default degree is effectively improved.

Objective To explore the effect of vaginal pressure feedback combined with pelvic floor muscle resistant training on stress urinary incontinence (SUI). Methods 125 women with SUI in our hospital from February, 2014 to May, 2015 were randomized into control group (n=65) and experimental group (n=60). The control group took Kegel exercise, which asked for patients to contract their pelvic floor muscles, while the experimental group first received biofeedback electrical stimulation for 20 minutes with XFT-2002 pelvic floor stimula-tor, then instructed the patients to contract their pelvic floor muscles and pressed the pneumatic probe which placed in vagina according to the voice navigation of XFT-0010 pelvic floor muscle stimulator after they learnt the contraction skill. Both groups received training with 10 seconds' contraction and 10 seconds' rest 30 minutes per day for 30 days in total. They were assessed by GRRUG and International Consulta-tion Incontinence Questionnaire-UI Short Form (ICIQ-SF). Results After treatment, the muscle strength of the pelvic floor (t=-3.570) and the scores of ICIQ (t=4.198) improved significantly in both groups (P<0.01), and was higher in the experimental group than in the control group (t=6.833, t=-2.445, P<0.01), as well as the therapeutic efficiency (Z=63.954, P<0.001). Conclusion Vaginal pressure feedback com-bined with pelvic floor muscle resistant training can further improve stress urinary incontinence in women.

Alcohol abuse leads to alcoholic liver disease and no effective therapy is currently available. Wuzhi Tablet (WZ), a preparation of extract fromthat is a traditional hepato-protective herb, exerted a significant protective effect against acetaminophen-induced liver injury in our recent studies, but whether WZ can alleviate alcohol-induced toxicity remains unclear. This study aimed to investigate the contribution of WZ to alcohol-induced liver injury by using chronic-binge and acute models of alcohol feeding. The activities of ALT and AST in serum were assessed as well as the level of GSH and the activity of SOD in the liver. The expression of CYP2E1 and proteins in the NRF2-ARE signaling pathway including NRF2, GCLC, GCLM, HO-1 were measured, and the effect of WZ on NRF2 transcriptional activity was determined. We found that both models resulted in liver steatosis accompanied by increased transaminase activities, but that liver injury was significantly attenuated by WZ. WZ administration also inhibited CYP2E1 expression induced by alcohol, and elevated the level of GSH and the activity of SOD in the liver. Moreover, the NRF2-ARE signaling pathway was activated by WZ and the target genes were all upregulated. Furthermore, WZ significantly activated NRF2 transcriptional activity. Collectively, our study demonstrates that WZ protected against alcohol-induced liver injury by reducing oxidative stress and improving antioxidant defense, possibly by activating the NRF2-ARE pathway.

Epigenetic pathways play a critical role in the initiation, progression, and metastasis of cancer. Over the past few decades, significant progress has been made in the development of targeted epigenetic modulators (e.g., inhibitors). However, epigenetic inhibitors have faced multiple challenges, including limited clinical efficacy, toxicities, lack of subtype selectivity, and drug resistance. As a result, the design of new epigenetic modulators (e.g., degraders) such as PROTACs, molecular glue, and hydrophobic tagging (HyT) degraders has garnered significant attention from both academia and pharmaceutical industry, and numerous epigenetic degraders have been discovered in the past decade. In this review, we aim to provide an in-depth illustration of new degrading strategies (2017-2023) targeting epigenetic proteins for cancer therapy, focusing on the rational design, pharmacodynamics, pharmacokinetics, clinical status, and crystal structure information of these degraders. Importantly, we also provide deep insights into the potential challenges and corresponding remedies of this approach to drug design and development. Overall, we hope this review will offer a better mechanistic understanding and serve as a useful guide for the development of emerging epigenetic-targeting degraders.
