简介：阴囊的精子抽取广泛地在非妨碍的精子缺乏的情况下在男不孕的治疗被使用。在睾丸以内识别spermatogeneticfoci为阴囊的精子抽取是批评的。二光子的激光扫描显微镜学(TPLSM)是深入地新鲜生活纸巾的在细胞的水平允许观察的一种基于autofluorescence的显微镜学技术并且不要求任何组织学的处理(固定或染色)。以前使用的波长没在精子上显示出phototoxicity。我们使用了TPLSM在新鲜老鼠检测spermatogeneticfoci没有破坏tunicaalbuginea的阴囊的实质。新鲜通过手术检索的睾丸在抽取以后在1h以内用TPLSM被观察。为每个动物的Contralateral睾丸用标准组织学被观察。用TPLSM，我们能通过tunicaalbuginea观察并且测量生精的小管的直径，类似于组织学的控制。在上皮的小管以内的结构也被观察，尽管他们的性质还得被识别。TPLSM是能检测spermatogeneticfoci的一种即时显微镜学技术。

简介：AbstractPurpose:Liver is the most frequently injured organ in abdominal trauma. Today non-operative management (NOM) is considered as the standard of care in hemodynamically stable patients, with or without the adjunct of angioembolisation (AE). This systematic review assesses the incidence of complications in patients who sustained liver injuries and were treated with simple clinical observation. Given the differences in indications of treatment and severity of liver trauma and acknowledging the limitations of this study, an analysis of the results has been done in reference to the complications in patients who were treated with AE.Methods:A systematic literature review searched "liver trauma" , "hepatic trauma" , "conservative management" , "non operative management" on MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials databases, EMBASE, and Google Scholar, to identify studies published on the conservative management of traumatic liver injuries between January 1990 and June 2020. Patients with traumatic liver injuries (blunt and penetrating) treated by NOM, described at least one outcome of interests and provided morbidity outcomes from NOM were included in this study. Studies reported the outcome of NOM without separating liver from other solid organs; studies reported NOM complications together with those post-intervention; case reports; studies including less than 5 cases; studies not written in English; and studies including patients who had NOM with AE as primary management were excluded. Efficacy of NOM and overall morbidity and mortality were assessed, the specific causes of morbidity were investigated, and the American Association for the Surgery of Trauma classification was used in all the studies analysed. Statistical significance has been calculated using the Chi-square test.Results:A total of 19 studies qualified for inclusion criteria were in this review. The NOM success rate ranged from 85% to 99%. The most commonly reported complications were hepatic collection (3.1%), followed by bile leak (1.5%), with variability between the studies. Other complications included hepatic haematoma, bleeding, fistula, pseudoaneurysm, compartment syndrome, peritonitis, and gallbladder ischemia, all with an incidence below 1%.Conclusion:NOM with simple clinical observation showed an overall low incidence of complications, but higher for bile leak and collections. In patients with grade III and above injuries, the incidence of bile leak, collections and compartment syndrome did not show a statistically significant difference with the AE group. However, the latter result is limited by the small number of studies available and it requires further investigations.

简介：AbstractBackground:The incubation period is a crucial index of epidemiology in understanding the spread of the emerging Coronavirus disease 2019 (COVID-19). In this study, we aimed to describe the incubation period of COVID-19 globally and in the mainland of China.Methods:The searched studies were published from December 1, 2019 to May 26, 2021 in CNKI, Wanfang, PubMed, and Embase databases. A random-effect model was used to pool the mean incubation period. Meta-regression was used to explore the sources of heterogeneity. Meanwhile, we collected 11 545 patients in the mainland of China outside Hubei from January 19, 2020 to September 21, 2020. The incubation period fitted with the Log-normal model by the coarseDataTools package.Results:A total of 3235 articles were searched, 53 of which were included in the meta-analysis. The pooled mean incubation period of COVID-19 was 6.0 days (95% confidence interval [CI]: 5.6-6.5) globally, 6.5 days (95% CI: 6.1-6.9) in the mainland of China, and 4.6 days (95% CI: 4.1-5.1) outside the mainland of China (P=0.006). The incubation period varied with age (P=0.005). Meanwhile, in 11 545 patients, the mean incubation period was 7.1 days (95% CI: 7.0-7.2), which was similar to the finding in our meta-analysis.Conclusions:For COVID-19, the mean incubation period was 6.0 days globally but near 7.0 days in the mainland of China, which will help identify the time of infection and make disease control decisions. Furthermore, attention should also be paid to the region- or age-specific incubation period.

简介：AbstractBackground:Although the use of expanded-criteria donors (ECDs) alleviates the problem of organ shortage, it significantly increases the incidence of delayed graft function (DGF). DGF is a common complication after kidney transplantation; however, the effect of DGF on graft loss is uncertain based on the published literature. Hence, the aim of this study was to determine the relationship between DGF and allograft survival.Methods:We conducted a retrospective, multicenter, observation cohort study. A total of 284 deceased donors and 541 recipients between February 2012 and March 2017 were included. We used logistic regression analysis to verify the association between clinical parameters and DGF, and Cox proportional hazards models were applied to quantify the hazard ratios of DGF for kidney graft loss.Results:Among the 284 deceased donors, 65 (22.8%) donors were ECD. Of the 541 recipients, 107 (19.8%) recipients developed DGF, and this rate was higher with ECD kidneys than with standard-criteria donor (SCD) kidneys (29.2% vs. 17.1%; P = 0.003). The 5-year graft survival rate was not significantly different between SCD kidney recipients with and without DGF (95.8% vs. 95.4%; P= 0.580). However, there was a significant difference between ECD kidney recipients with and without DGF (71.4% vs. 97.6%; P = 0.001), and the adjusted hazard ratio (HR) for graft loss for recipients with DGF was 1.885 (95% confidence interval [CI] = 1.305–7.630; P = 0.024). Results showed that induction therapy with anti-thymocyte globulin was protective against DGF (odds ratio= 0.359; 95% CI= 0.197–0.652; P= 0.001) with all donor kidneys and a protective factor for graft survival (HR = 0.308; 95% CI = 0.130–0.728; P = 0.007) with ECD kidneys.Conclusion:DGF is an independent risk factor for graft survival in recipients with ECD kidneys, but not SCD kidneys.
