Safety and efficacy of traditional Chinese medicine,Qiaoshao formula,combined with dapoxetine in the treatment of premature ejaculation: An open-label,real-life,retrospective multicentre study in Chinese men

To evaluate the safety and efficacy of Chinese medicine, Qiaoshao formula combined with dapoxetine was used for the treatment of premature ejaculation in a real-life setting. Nine hundred and five males diagnosed with premature ejaculation were reviewed in this retrospective cohort study. We divided the patients into two groups: dapoxetine alone and Qiaoshao formula combined with dapoxetine according to actual interventions provided to patients in clinics. The perceived intravaginal ejaculation latency time and the premature ejaculation profile measures markedly improved in both groups. However, in men with severe premature ejaculation (baseline perceived intravaginal ejaculation latency time <1 min) and those with baseline age ≤30 years, the perceived intravaginal ejaculation latency time was slightly but significantly longer with combined therapy than with dapoxetine alone (p < .05). Therefore, combined therapy involving the Qiaoshao formula and dapoxetine proved to safe as well as effective for treating premature ejaculation while prolonging the perceived intravaginal ejaculation latency time, which significantly improved the overall satisfaction of the patient and likely that of the couple.     

Expression of brain-derived neurotrophic factor in rapid ejaculator rats: A further study

Limited evidence has indicated that brain-derived neurotrophic factor (BDNF) may be involved in the neurobiology of premature ejaculation (PE). This study aimed to investigate BDNF levels in the central and peripheral nervous systems of a rapid ejaculation model. Eighteen male rats were selected and classified as ‘sluggish’, ‘normal’ and ‘rapid’ ejaculators on the basis of ejaculation frequency during copulatory behavioural tests. BDNF levels in specific brain regions, spinal cord and serum were determined by enzyme-linked immunosorbent assay (ELISA). Consistent with the results in PE patients, the concentration of serum BDNF decreased significantly from the sluggish rats to normal and rapid rats. Besides, in both brain regions and spinal cord, the sluggish group had the highest BDNF levels, while the rapid group had the lowest BDNF levels. Regression analyses of the expression of BDNF presented positive correlations between serum and brain (r = 0.958, p < .001), and between serum and spinal cord (r = 0.967, p < .001) respectively. Our findings suggested insufficient BDNF in the nervous system and serum may lead to rapid ejaculation. The current study adds to the evidence that BDNF is involved in the regulation of ejaculation.     

Bibliometric Analysis of the Top-Cited Articles on Unicompartmental Knee Arthroplasty

BackgroundUnicompartmental knee arthroplasty (UKA) has been proven to be an effective surgical technique for unilateral compartment osteoarthritis. The purpose of this study is to identify and analyze the top 100 cited articles in the field of UKA research.MethodsPublications on UKA from 1980 to 2020 in the Web of Science database were retrieved. The characteristics of the top 100 cited articles were analyzed, including information of publications and citations, level of evidence, and research interests.ResultsThe number of publications and citations increased over time. The majority of the highly cited articles were from the Nuffield Orthopedic Centre (Oxford, England) and the Brigham and Women’s Hospital (Boston, USA). Long-term outcome of UKA and comparison between UKA and TKA gathered most research interests. The most frequently occurring keywords were “survival” and “revision.” Since 2012, “life quality” and “robotics” have been used. There was no level I evidence, and most studies provided level IV evidence.ConclusionThere was a rising trend in publications and citations in the field of UKA research, the majority of them were from a few centers, and were low-level evidence. Most studies focused on the long-term outcomes of UKA; in recent years, patient satisfaction and navigation surgery have become new research trends.     

Systematic review of outcomes and meta-analysis of risk factors for prognosis after liver resection for hepatocellular carcinoma without cirrhosis

Long-term overall survival (OS) after liver resection for non-cirrhotic hepatocellular carcinoma (NCHCC) has been reported recently. The aim of this study was to review outcomes systematically and analyze risk factors for survival after surgical resection for HCC without cirrhosis. A literature search was performed of the PubMed and Embase databases for papers published between January 1995 and October 2012, which focused on hepatic resection for HCC without underlying cirrhosis. Cochrane systematic review methodology was used for this review. Outcomes were OS, operative mortality and disease-free survival (DFS). Pooled hazard ratios (HR) were calculated using the random effects model for parameters considered as potential prognostic factors. Totally, 26 retrospective case series were eligible for inclusion. The 1-, 3- and 5-year OS rate after surgical resection of NCHCC ranged from 62% to 100%, 46.3%–78.0%, and 30%–64%, respectively. The corresponding DFS rates ranged from 48.7% to 84%, 31.0%–66.0%, and 24.0%–58.0%, respectively. Five variables were related to poor survival: multiple tumors (HR 1.68, 95%CI 1.25–2.11); larger tumor size (HR 2.66, 95%CI 1.69–3.63); non-clear resection margin (R0 resection) (HR 3.52, 95%CI 1.63–5.42); poor tumor stage (HR 2.61, 95%CI 1.64–3.58); and invasion of the lymphatic vessels (HR 4.85, 95%CI 2.67–7.02). In sum, hepatic resection provides excellent OS rates for patients with NCHCC, and results have tended to improve recently. Risk factors for poor prognosis comprise multiple tumors, lager tumor size, non-R0 resection and invasion of the lymphatic vessels.     

Mid‐ to Long‐Term Outcomes of Cementless Modular,Fluted, Tapered Stem for Massive Femoral Bone Loss in Revision Total Hip Arthroplasty

ObjectiveTo evaluate mid‐ to long‐term results of revision total hip arthroplasty for massive femoral bone loss using a cementless modular, fluted, tapered stem.MethodsThis is a retrospective study performed at a single hospital. During the period of January 2007 to January 2015, 33 patients (34 hips) underwent primary revision surgery with cementless modular, fluted, tapered stems due to femoral bone loss. Sixteen men and 17 women were included in the study, with an average age of 63.9 ± 11.7 years (range, 27 to 88 years). Operative data including operative duration, length of incision, drainage volume and duration, blood loss and transfusion, cases of bone graft and extended trochanteric osteotomy were recorded. Clinical evaluation was performed using Harris hip score (HHS), visual analogue scale (VAS), and patients'' satisfaction. Radiographic data including femoral stem fixation, subsidence, integrin of allograft bone, and leg length discrepancy were assessed. Complications and survivorship were evaluated using Kaplan–Meier survival rate.ResultsThe mean follow‐up was 9.1 ± 2.5 years (range, 5–13 years). The Harris hip score was 43.6 ± 11.5 preoperatively and maintained at 86.5 ± 6.6 at the time of latest follow‐up (P < 0. 05). The X‐ray showed bone ingrowth fixation in 30 hips (88%), fibrous stable fixation in three hips (9%), and instability in one hip (3%). The average stem subsidence was 3.9 ± 2.2 mm (range, 1 to 10 mm). The mean difference in leg length in our study was 3.3 ± 2.7 mm (range, 0 to 10 mm), and the leg length discrepancy in 28 (82%) patients was within 5 mm. No case of junction fracture was observed. Seven (21%) intraoperative fractures occurred in our study. Three (9%) cases with infection were observed after revision. Six (18%) patients had lower limb vein thrombosis. The survivorship of prostheses with re‐revision for any reason was 95% (95% CI, 12.0 to 13.0) at the 10‐year follow‐up. Three (9%) re‐revisions were needed, including one for aseptic loosening, one for dislocation, and one for infection.ConclusionThe mid‐ to long‐term results of revision total hip arthroplasty with the cementless modular, fluted, tapered stems are encouraging for massive femoral bone loss.
