2.Dapoxetine for premature ejaculation: Advances in clinical studies.
National Journal of Andrology 2015;21(10):931-936
Premature ejaculation (PE) is a most common sexual dysfunction, for which dapoxetine, a novel selective serotonin (5-HT) re-uptake inhibitor (SSRI), is the only licensed oral medicine at present. With the advantages of fast absorption, rapid action, on-demand medication, and short half-life time, dapoxetine has been proved by clinical trials to be effective in prolonging the intravaginal ejaculation latency time (IELT) and improving the overall condition of PE patients in various areas and populations. Compared with the traditional SSRIs, dapoxetine has a better safety and tolerability. The most frequently reported dapoxetine-related adverse events include nausea, diarrhea, headache and dizziness, but with very few severe or serious cases.

Objective To evaluate the efficacy of post-operative radiotherapy and prognosis of renal cell carcinoma(RCC). Methods Between 1981 and 1998 , 90 s uch patients with disease limited to the kidney underwent nephrectomy at our ins titution. According to TNM classification(UICC,1997) the pathological stage was: Ⅰin 27 patients(30%),Ⅱ in 18 (20%), Ⅲ in 35(38.9%), and Ⅳ in 10(11.1%).Post - operative irradiation, with a median dose of 50?Gy in 25 fractions over 5 weeks w as given to 52 patients in 3~5weeks after surgery, using AP-PA opposing portal s or oblique portals. Results The 5- and 10-year survival rates in the irradiate d patients(S+Rt) were 75% and 60%,respectively, but in the non-irradiated patien t s(S) 50% and 40%, respectively.This difference is statistically significant. 5- y ear survival rates by TNM stage in the two groups were as follows: stageⅠ:S 67 %,S+Rt 100%;stageⅡ: S 55%,S+Rt 71%;stageⅢ: S 47%,S+Rt 65% (P=0 .010);stageⅣ: S 0%, S+Rt 43%.Diseases recurred locally in a total of 12 patients: 3 had tumo r b ed recurrence and 6 had regional lymph node recurrence and 3 had both. Local rec urrence in S was 29% and that of S+R was 2% (P=0.001). and local recurrence by T NM stage:Ⅲ were 33% and 5%, respectively. One patient developed radiation-indu c ed small bowel obstruction which necessitated surgical intervention, but no pat i ent died from radiotherapy-induced complications. By multivariate analysis: per f ormance status, symptomatic presentation, lymph node involvement, post-operativ e radiation and post-operative residual were all independent predictors of overa l l survival in the RCC patients. Conclusions In renal cell carcinoma, radiothera py is beneficial in reducing the locoregional recurrence. Radiotherapy has a sup prisingly positive effect on both local control and survival in TNM stage Ⅲ pat ients. Performance status, symptomatic presentation, lymph node involvement, pos t-operative radiation and post-operative residual are prognostic indicators of RCC. TNM staging is superior to Robson staging in predictive values .

Objective To compare the effects of general anesthesia versus combined epidural?general anesthesia on postoperative complications in the patients undergoing thoracic surgery. Methods Two hundred twenty?one patients of both sexes, aged 18-80 yr, weighing 36-100 kg, of American Society of Anesthesiologists physical status Ⅰ?Ⅲ, scheduled for elective thoracic surgery, were randomly divided into either combined epidural?general anesthesia group ( group GE, n=112) or general anesthesia group ( group GA, n=109) . The patients were further allocated to high?risk population and low?risk population. Anesthesia was induced with target?controlled infusion of remifentanil and iv injection of propofol, sufentanil and rocuronium. A double?lumen endotracheal tube was placed, and the patients were mechanically ventilated. Partial pressure of end?tidal CO2 was maintained at 30-40 mmHg. Anesthesia was maintained with inhalation of 1% sevoflurane, target?controlled infusion of remifentanil, iv infusion of propofol, and intermittent iv boluses of sufentanil. 2% lidocaine 4 ml∕h was infused epidurally in group GE, and normal saline 4 ml∕h was given in group GA. Bispectral index value was maintained at 40-60 during surgery. Patient?controlled epidural analgesia ( PCEA ) was performed after surgery. PCEA solution contained
0.125% ropivacaine and sufentanil 0.5μg∕ml ( in 250 ml of normal saline) . The PCEA pump was set up to deliver a 2 ml bolus dose with a 20?min lockout interval and background infusion at 4 ml∕h, and visual analogue scale ( VAS) score was maintained less than 4. When VAS score ≥ 5, sufentanil 5 μg was injected intravenously as the rescue analgesic. The requirement for rescue analgesics after surgery, length of hospital stay after surgery, complications during postsurgical hospital stay ( cardiovascular events, cardiac insufficiency, acute coronary syndrome, pulmonary infection, stroke, transient cerebral ischemic attack) , and death within 30 days after surgery were recorded. Results Compared with group GE, the incidence of postsurgical cardiovascular events and atrial fibrillation was significantly decreased in group GA ( P<0.05) . In the high?risk population, compared with group GE, the length of hospital stay after surgery was significantly shortened, and the incidence of postsurgical atrial fibrillation was decreased in group GA ( P<0.05) . In the low?risk population, compared with group GE, the length of hospital stay after surgery was significantly shortened (P<0.05), and no significant change was found in the incidence of postsurgical complications, requirement for rescue analgesics after surgery, and fatality rate in group GA (P>0.05). Conclusion Compared with combined epidural?general anesthesia, general anesthesia alone provides lower occurrence of postsurgical complications for the patients undergoing thoracic surgery, and offers advantage for the high?risk patients having underlying diseases before surgery.

This study aimed to investigate the immune adjuvant effect and mechanism induced by chitosan nanoparticles carrying pJME/GM-CSF. In this study, plasmid DNA (pJME/GM-CSF) was encapsulated in chitosan to prepare chitosan-pJME/GM-CSF nanoparticles using a complex coacervation process. Immunohistochemistry was used to detect the type of infiltrating cells at the site of intramuscular injection. The phenotype and functional changes of splenic DCs were measured by flow cytometry after different immunogens were injected intramuscularly. The killing activity of CTLs was assessed using the lactate dehydrogenase (LDH) release assay. The preparation of chitosan-pJME/GM-CSF nanoparticles matched the expected theoretical results. Our results also found that, after pJME/GM-CSF injection, the incoming cells were a mixture of macrophages, neutrophils, and immature DCs. Meanwhile, pJME/GM-CSF increased the expression of MHC class II molecules on splenic DCs, and enhanced their Ag capture and presentation functions. Cell-mediated immunity was induced by the vaccine. Furthermore, chitosan-pJME/GM-CSF nanoparticles outperformed the administration of standard pJME/GM-CSF in terms of DC recruitment, antigen processing and presentation, and vaccine enhancement. These findings reveal that chitosan could be used as delivery vector for DNA vaccine intramuscular immunizations, and enhance pJME/GM-CSF-induced cellular immune responses.
