Objective:To assesss the effectiveness of dapoxetine in the treatment of premature ejaculation.Methods:Both English and Chinese studies involving men with prematrue ejaculation who were treated with dapoxetine from the Cochrane Library,MEDLINE,EMBASE and CNKI,CBM,VIP between 1979 and 2009.were included in the randomized controlled trials(RCTs) and the data processed by RevMan.Results:Five RCTs involving 4433 patients were included in the Meta analysis,of which 3 were of grade A and 2 were of grade B according to the quality evaluation of methodology.Intravaginal ejaculatory latency time(IELT),patient-reported global impression of change(PGI),satisfaction with sexual intercourse(SWSI),perceived control over ejaculation(PCOE),personal distress related to ejaculation(PDRE) were used for assessment.Meta analysis based on included studies of patients having been treated with dapoxetine for 9-24 weeks showed that:(1) the difference of the patients' IELT between treatment group and control group was statistically significan [P

Objective:To investigate the etiology of high myopia and the correlation between best corrected visual acuity and myopic diopter and fundus lesions.Methods:The clinical data of 112 patients (198 eyes) with high myopia diagnosed in Yuyao Hospital of Traditional Chinese Medicine from December 2018 to December 2019 were retrospectively analyzed. The factors that influence high myopia were analyzed. Myopic diopter, the type and severity of fundus lesions, and best corrected visual acuity were evaluated. The correlation between observation indexes was analyzed.Results:The occurrence of high myopia was related to partial lens opacity, fundus aberrations, corneal pannus and heredity. Unconditional multivariable logistic regression revealed that parental myopia [73 (83.91%) vs. 39 (57.34%)], outdoor activities < 4.17 h [47 (89.36%) vs. 24 (61.54%), 26 (68.42%), 20 (65.42%)] are the risk factors of high myopia ( χ2 = 13.427, 10.300, P < 0.05 or P < 0.01). Pearson linear correlation analysis showed that myopia diopter was negatively correlated with best corrected visual acuity ( r = -0.729, P < 0.001). Tigroid fundus, tilted optic disc, β-zone parapapillary atrophy and posterior polar annular choroidal dystrophy were positively correlated with best corrected visual acuity ( r = 0.461, 0.732, 0.528, 0.825, P < 0.05 or P < 0.001). The severity of lesion was negatively correlated with best corrected visual acuity( r = -0.673, P < 0.001). Conclusion:The myopia diopter and fundus lesion characteristics in patients with high myopia are closely related to best corrected visual acuity, which can be used to evaluate patient's condition and provide guidance for prevention and treatment of high myopia.

Aggregatibacter aphrophilus is a member of the normal flora of the human oral cavity and pharynx, a Gram-negative fastidous bacteria, belonging to agglomerates, which is a normal mixed oropharyngeal flora in humans, most commonly colonized on the surface of oral mucosa. This bacterial infection is rare in clinical practice, and it is difficult to culture and identify the bacteria, which is easy to be missed. A patient with intracranial infection was admitted to Huaihe Hospital, who showed fever and headache as the main clinical manifestations, and Aggregatibacter aphrophilus was detected by the metagenomic next-generation sequencing of cerebrospinal fluid. The patient′s symptoms were significantly improved after anti-infection treatment.

Objective To investigate the long-term safety and effectiveness of withdrawal of hepatitis B immuneglobulin (HBIG) and/or nucleos(t)ide analogues (NAs) to prevent hepatitis B virus (HBV) reinfection in liver transplant recipients with hepatitis B-related diseases after successful vaccination. Methods Baseline data of 76 liver transplant recipients undergoing hepatitis B immune reconstitution after receiving hepatitis B vaccines were retrospectively analyzed. The vaccination and response, the follow-up results of respondents with HBIG and/or NAs withdrawal, and the reinfection of HBV after withdrawal of HBIG and/or NAs were analyzed. Results The time interval from liver transplantation to hepatitis B vaccination was 26 (20, 40) months. The time interval from vaccination to response was 15 (8,27) months. Initially, 76 recipients withdrew HBIG, and 36 recipients withdrew HBIG and NAs. During the follow-up, 12 of 76 recipients who withdrew HBIG resumed use of HBIG, and 16 of 36 recipients who withdrew HBIG and NAs resumed use of NAs. The withdrawal time of HBIG and NAs was 135 (98,150) and 133 (34,149) months, respectively. Sixteen respondents did not receive booster, and 36 respondents received boosters on a regular basis. The time interval between the first booster and HBIG withdrawal was 44 (11,87) months. No significant differences were observed in baseline data between the respondents with and without boosters (all P>0.05). During the follow-up, 9 recipients were lost to follow-up, 5 were re-infected with HBV, 3 died, and 1 recipient developed graft loss and underwent secondary liver transplantation. Among 5 recipients re-infected with HBV, 4 cases had virus mutation. Significant differences were found between re-infected and uninfected patients regarding withdrawal of NAs and hepatitis B e antigen (HBeAg) positive before transplantation (both P<0.05). Conclusions Long-term withdrawal of HBIG is feasible and safe for recipients with successful hepatitis B immune reconstitution after liver transplantation for hepatitis B-related diseases. Nevertheless, whether antiviral drugs can be simultaneously withdrawn remains to be validated.
