Noncompaction of the ventricular myocardium is a rare form of congenital cardiomyopathy with a high incidence of cardiovascular complications. It frequently manifests in an isolated form, namely isolated noncompaction of the ventricular myocardium. Not only does noncompaction of the ventricular myocardium associate with other congenital cardiac malformations, but also with other neuromuscular disorders. The purpose of this study was to explore the correlation of hypogenetic lung with myocardial noncompaction in terms of the clinical course of one of our patients.

The fluorescent reagent salicylaldehyde benzoylhydrazone(SABH) was synthesized and its ionization constants were estimated spectrophotometrically. The fluorescent reaction of this reagent with gallium was studied. Based on this chelation reaction, a spectrofluorimetric method was developed for the determination of gallium in a water medium at pH 3.2. Under these conditions, the Ga SABH complex has excitation and emission maxima at 372 and 455 nm, respectively. The linear range of the method was 0～150 μg/L and the detection limit was 0.36 μg/L of gallium when a standard addition method was used in the assay. The molar ratio of gallium to the reagent was 1∶3. The interference of other ions was studied. The extraction with n butyl acetate from a 6 mol/L hydrochloric acid medium was used to separate Ga from the interfering elements in semiconductor silicon and geological samples, and themethod has been successfully applied to the determination of gallium in these samples.

Spondyloarthropathies （SpAs） include five categories： ankyloslng spondyllns （AS）, reactive arthritis （ReA）,psoriatic arthritis （PsA）, enteropathic arthritis （EA） and undifferentiated spondyloarthropathy （USpA）.2 ReA is an aseptic arthritis occurring after extra-articular infections, particularly genitourinary （GU） or gastrointestinal （GI） tracts. When arthritis is accompanied by conjunctivitis and urethritis, the diagnosis of Reiter syndrome will be suitable for this clinical triad; however, the term ＂ReA＂ has been proposed to substitute for Reiter syndrome.

目的基于倾向性评分匹配法(PSM)分析术前血钙水平与老年心外科手术患者术后谵妄的关系。方法回顾性分析2020年5月至2023年10月德阳市人民医院心外科接受手术治疗的166例老年患者临床资料,依据术后住院期间是否发生谵妄将其分为发生组(52例)、未发生组(114例),采用PSM对两组患者临床资料进行匹配后得到组间协变量均衡的样本,单因素、logistic多因素回归分析法明确影响老年心外科手术患者术后谵妄的危险因素,受试者工作特征曲线(ROC)评估术前血钙水平预测老年心外科手术患者术后谵妄的效能。结果PSM后,共得到47对组间协变量均衡的样本。发生组、未发生组合并糖尿病比例、术后输注红细胞比例及白蛋白、血肌酐、血钙、神经元特异性烯醇酶(NSE)水平差异有统计学意义(P0.05)。Logistic多因素回归分析,结果显示,合并糖尿病(OR=1.790,95%CI 1.627~1.952)、白蛋白水平低(OR=1.804,95%CI 1.516~2.092)、血肌酐水平高(OR=1.844,95%CI 1.563~2.125)、血钙水平高(OR=1.835,95%CI 1.612~2.058)、NSE水平高(OR=1.840,95%CI 1.524~2.157)、术后输注红细胞(OR=1.808,95%CI 1.458~2.254)是影响老年心外科手术患者术后谵妄的危险因素,即上述指标与老年心外科手术患者术后谵妄有关。ROC曲线结果显示,术前血钙水平预测老年心外科手术患者术后谵妄的敏感度、特异度、AUC分别为87.50%、77.30%、0.906。结论老年心外科手术患者术后谵妄发生风险较高,术前血钙水平与老年心外科手术患者术后谵妄密切相关,且术前血钙水平升高可能是老年心外科手术患者术后谵妄发生的有效预测因子。

An analytical model is proposed for input buffer router architecture Network-on-Chip （NoC） with finite size buffers. The model is developed based on M/G/ 1/K queuing theory and takes into consideration the restriction of buffer sizes in NoC. It analyzes the packet＇s sojourn time in each buffer and calculates the packets average latency in NoC The validity of the model is verified through simulation. By comparing our analytical outcomes to the simulation results, we show that the proposed model successfully captures the performance characteristics of NoC, which provides an efficient performance analysis tool for NoC design.
