摘要 目的：回顾性对比神经内镜手术与小骨窗开颅手术治疗高血压脑出血（HICH）疗效。方法：回顾性选取2018年7月~2021年3月期间在联勤保障部队第909医院治疗的83例HICH患者的临床资料。根据手术方式的不同,将患者分为A组（n=41）和B组（n=42）,A组患者采用小骨窗开颅手术治疗,B组患者采用神经内镜手术治疗,对比两组围术期指标、并发症发生率、神经功能、生活能力、神经损伤指标及预后。结果：与A组相比, B组的手术时间、住院时间明显缩短,术中出血量减少,血肿清除率升高（P<0.05）。B组术后1周美国国立卫生研究院卒中量表（NIHSS）评分低于A组,Barthel指数评分高于A组（P<0.05）。B组术后1周神经元特异性烯醇化酶（NSE）、S100B 蛋白（S100B）、髓鞘碱性蛋白（MBP）、胶质纤维酸性蛋白（GFAP）水平低于A组（P<0.05）。B组的并发症发生率小于A组（P<0.05）。B组的预后良好率高于A组（P<0.05）。结论：神经内镜手术、小骨窗开颅手术治疗HICH均可获得较好的疗效,其中神经内镜手术在缩短手术时间、住院时间,减少术中出血量和并发症发生率,提高血肿清除率,减轻神经功能损伤,促进患者生活能力改善,改善患者预后方面的效果更为显著。     

腹腔镜下子宫血管阻断术联合子宫肌瘤剜除术治疗子宫肌瘤的回顾性研究

摘要 目的：回顾性分析子宫肌瘤剜除术联合腹腔镜下子宫血管阻断术治疗子宫肌瘤的临床疗效。方法：分析2017年6月~2019年7月期间我院收治的子宫肌瘤患者的临床资料（n=150）。根据手术方法的不同将患者分为A组（腹腔镜下子宫肌瘤剜除术治疗,73例）和B组（腹腔镜下子宫血管阻断术联合子宫肌瘤剜除术治疗,77例）,对比两组术中、内分泌激素、术后恢复指标、妊娠情况、并发症发生率及复发率。结果：两组患者手术时间对比无统计学差异（P>0.05）,B组的术中出血量少于A组,术后排气时间、住院天数、下床活动时间短于A组（P<0.05）。A组术前、术后3个月、术后6个月黄体生成素(LH) 、卵泡刺激素(FSH) 、雌二醇(E₂) 水平组内对比无统计学差异（P>0.05）。B组术前、术后3个月、术后6个月E₂水平呈降低后升高趋势,LH、FSH水平呈升高后降低趋势（P<0.05）。B组术后3个月LH、FSH水平高于A组,E2水平低于A组（P<0.05）。与A组相比,B组的并发症发生率明显下降,组间对比有差异（P<0.05）。B组的妊娠率高于A组,子宫肌瘤复发率低于A组（P<0.05）。两组流产率组间对比无统计学差异（P>0.05）。结论：与单纯子宫肌瘤剜除术相比,结合腹腔镜下子宫血管阻断术治疗子宫肌瘤患者可减少术中出血量,促进患者术后恢复,降低并发症发生率及复发率,虽然其对卵巢功能有轻微、短暂性影响,但可逐步恢复,且有利于提高妊娠率。

Plasma N-glycome composition associates with chronic low back pain

Background

Low back pain (LBP) is the symptom of a group of syndromes with heterogeneous underlying mechanisms and molecular pathologies, making treatment selection and patient prognosis very challenging. Moreover, symptoms and prognosis of LBP are influenced by age, gender, occupation, habits, and psychological factors. LBP may be characterized by an underlying inflammatory process. Previous studies indicated a connection between inflammatory response and total plasma N-glycosylation. We wanted to identify potential changes in total plasma N-glycosylation pattern connected with chronic low back pain (CLBP), which could give an insight into the pathogenic mechanisms of the disease.

Logistic Bayesian LASSO for identifying association with rare haplotypes and application to age-related macular degeneration

Rare variants have been heralded as key to uncovering "missing heritability" in complex diseases. These variants can now be genotyped using next-generation sequencing technologies; nonetheless, rare haplotypes may also result from combination of common single nucleotide polymorphisms available from genome-wide association studies (GWAS). The National Eye Institute's data on age-related macular degeneration (AMD) is such an example. Studies on AMD had identified potential rare variants; however, due to lack of appropriate statistical tools, effects of individual rare haplotypes were never studied. Here we develop a method for identifying association with rare haplotypes for case-control design. A logistic regression based retrospective likelihood is formulated and is regularized using logistic Bayesian LASSO (LBL). In particular, we penalize the regression coefficients using appropriate priors to weed out unassociated haplotypes, making it possible for the rare associated ones to stand out. We applied LBL to the AMD data and identified common and rare haplotypes in the complement factor H gene, gaining insights into rare variants' contributions to AMD beyond the current literature. This analysis also demonstrates the richness of GWAS data for mapping rare haplotypes-a potential largely unexplored. Additionally, we conducted simulations to investigate the performance of LBL and compare it with Hapassoc. Our results show that LBL is much more powerful in identifying rare associated haplotypes when the false positive rates for both approaches are kept the same.     

Sampling for conditional inference on case-control data

The problem of exact conditional inference for discrete multivariate case-control data has two forms. The first is grouped case-control data, where Monte Carlo computations can be done using the importance sampling method of Booth and Butler (1999, Biometrika86, 321-332), or a proposed alternative sequential importance sampling method. The second form is matched case-control data. For this analysis we propose a new exact sampling method based on the conditional-Poisson distribution for conditional testing with one binary and one integral ordered covariate. This method makes computations on data sets with large numbers of matched sets fast and accurate. We provide detailed derivation of the constraints and conditional distributions for conditional inference on grouped and matched data. The methods are illustrated on several new and old data sets.
