Although premature ejaculation (PE) is a common type of male sexual dysfunction, to date we lack a unified definition of PE. The multidimensional definition of PE has been accepted by more and more clinicians. Intravaginal ejaculatory latency time (IELT) is one of the three important dimensions (time to ejaculation, inability to control or delay ejaculation, and negative consequences) for defining PE. Rapid ejaculation is one of the core symptoms of PE and IELT is an objective measurement as well as an important tool for the evaluation of PE. This article reviews estimated IELT, stopwatch-measured IELT, the correlation between estimated and stopwatch-measured IELT, and the factors affecting IELT in the general male population, PE patients, and those complaining of PE.

The use of immune checkpoint inhibitors (ICIs) has changed the clinical outcome of non-small cell lung cancer (NSCLC), with the widespread application of ICIs, immune-related adverse events (irAEs) have also appeared. Immune checkpoint inhibitor pneumonitis (CIP) is a serious adverse event of ICIs treatment that needs attention. Therefore, early identification of high-risk groups of CIPs and early intervention can reduce the occurrence of permanent drug withdrawal and severe CIPs, thereby improving patients′ prognosis.

Objective To investigate the factors predicting endoscopic stone extraction complications during operation and 1 week within operation. Methods The clinical data of 136 patients with common duet stones during endoscopic procedures and 1 week within procedures were collected, and the impacts of the number, size of stones, and the first-attack versus recurrent-attack stone, with or without cholangeitis on the complications during operation and 1 week within operation were analyzed, and the effect of nasobiliary drainage was investigated. Results The success rate in single-stone group was high, the incidences of complications during endoscopy including sphincter hemorrhage, cardiac laceration, hyperamylasemia, acute pancreatitis were significantly lower than those in the multi-stones group ( P < 0. 05 ). The group of < 2 cm stone also had high success rate of stone extraction, the incidences of complications including sphincter hemorrhage, stone impaction, cardiac laceration, hyperamylasemia, acute pancreatitis were significantly lower than those in the ≥2 cm group. The first-attack group had low success rate of stone extraction, the incidences of complications including sphincter hemorrhage, stone impaction, hyperamylasemia, acute pancreatitis and biliary infection were significantly higher than those in the recurrent-attack group. The patients with cholangeitis had low success rate of stone extraction, the incidences of complications including sphincter hemorrhage, hypoxemia, hyperamylasemia, acute pancreatitis and biliary infection were significantly higher than those without cholangeitis. After nasobiliary drainage, the incidences of hyperamylasemia, acute pancreatitis and biliary infection significantly decreased while the incidence of sphincter hemorrhage significantly increased. Conclusions The number, size of stones, and the first-attack versus recurrent-attack stone, symptoms with orwithout cholangeitis could predict the complications of stone extraction;post-ERCP nssobiliary drainage could decrease the complications, but increase the possibility of sphincter hemorrhage.

Objective To establish a method for the rapid detection of hepatitis E virus (HEV)from serum samples based on fluorescence quantitative PCR.Methods (1 )One-hundred HEV sequences including our country popular three major genotypes were obtained from the GeneBank with the Vector NTI software.The proper sequence was selected to design and synthesize the primers of the fluorescence quantitation and the Taqman probe.(2)The amplification region PCR fragment was transcribed in vitro to synthesize cRNA standard,at the same time the trace serum virus lysate was introduced into a universal real-time TaqMan PCR assay.(3)10 clinical serum samples were collected from the patients with clinical hepatitis E and detected by using the established method for further verifying this method.Results This detection technique could effectively detect the serum samples in the pa-tients with genotype I and genotype IV hepatitis E positive,while the serum detection in the patients with other virus infectious dis-eases had the negative results,which verified that this RT-PCR detection technique had higher specificity and good reliability.The detection results from 10 clinical serum samples further verified that this method was rapid,convenient and sensitive with good re-peatability.Conclusion A fluorescence quantitative RT-PCR detection technique suitable for detecting main genotypes of HEV in China population is established,which can meet the demand of early and rapid diagnosis for HEV.
