目的 :探讨对由延迟的心室纤颤引起的心脏骤停的治疗方法。方法 :将 32只延迟心室纤颤 (10分钟心室纤颤 )动物模型的大鼠随机分为 4组 (0 -min组 ,2 -min组 ,4-min组及 6 -min组 ) ,分别在心肺复苏前、心肺复苏后 2分钟、4分钟、6分钟行试验电除颤 ,对未能转复者继续心肺复苏及补救电除颤。结果 :0 -min组 ,2 -min组无大鼠能通过试验电除颤成功恢复自主心率 ,而 6 -min组有 7只大鼠 ;与另外两组相比 ,4-min组及 6 -min组具有更长的生存时间。此外 ,6 -min组恢复自主心率所需的试验电除颤次数、补救电除颤次数及总除颤能量均显著地较其他三组为低。结论 :我们认为对延迟的心室纤颤在电除颤前应进行至少 4～ 6分钟的心肺复苏。

目的　探讨联合应用钠氢离子交换抑制剂(NHE I)Cariporide与肾上腺素在心肺复苏中的效果。方法　 16只历经 12min室颤的大鼠配对分为 2组 (Cariporide组及对照组 ) ,分别在心肺复苏 (CPR)前注入Cariporide或等容量的生理盐水。CPR第 2min结束前始注入肾上腺素 ,使CPP维持在 2 5mmHg以上。对照组与匹配的Cariporide组有对应的除颤时间。对心肺复苏 8min后未能自动复率大鼠进行电除颤。结果　与对照组相比 ,以同样的高度进行胸前心脏按压 ,cariporide组须较小剂量的肾上腺素便可获得较高、持续时间较长的冠脉灌注压 (P <0 0 5 ) ,较高的复苏率 (P <0 0 5 )、较少的复苏后异位室性心律失常 (P <0 0 0 1)、较好的血流动力学效果及较长的生存时间 (P <0 0 5 )。结论　联合应用Cariporide及肾上腺素可提高心室纤颤的复苏效果。

Hyperlipidemia is very common after liver transplantation and can be observed in up to 71% of patients. The etiology of lipid disorders in these patients is multifactorial, with different lipid profiles observed depending on the immunosuppressive agents administered and the presence of additional risk factors, such as obesity, diabetes mellitus and nutrition. Due to recent improvements in survival of liver transplant recipients, the prevention of cardiovascular events has become more important, especially as approximately 64% of liver transplant recipients present with an increased risk of cardiovascular events. management of dyslipidemia and of other modifiable cardiovascular risk factors, such as hypertension, diabetes and smoking, has therefore become essential in these patients. Treatment of hyperlipidemia after liver transplantation consists of life style modification, modifying the dose or type of immunosuppressive agents and use of lipid lowering agents. At the start of administration of lipid lowering medications, it is important to monitor drugdrug interactions, especially between lipid lowering agents and immunosuppressive drugs. Furthermore, as combinations of various lipid lowering drugs can lead to severe side effects, such as myopathies and rhabdomyolysis, these combinations should therefore be avoided. To our knowledge, there are no current guidelines targeting the management of lipid metabolism disorders in liver transplant recipients. This paper therefore recommends an approach of managing lipid abnormalities occurring after liver transplantation.

BACKGROUND The most widely accepted treatment for pediatric supracondylar humeral fracture is closed reduction and percutaneous pinning(CRPP). However, there is debate regarding the technique that is utilized, whether crossed or lateral pinning, and the number of pins *** To compare the functional and radiological outcomes of lateral and cross pinning in the management of humeral supracondylar *** A retrospective analysis was performed on 101 patients who were surgically managed by either one of the CRPP techniques from 2015 to 2019. Several clinical parameters were taken into account, including pre-and post-intervention Baumann angle, as well as scores for pain, range of motion, function, and stability. Statistical analysis was performed to study the outcomes of the utilized *** Amongst our study sample, which included 63 males and 38 females with a mean age of 5.87 years, about one-third of the patients underwent crossed pinning fixation configuration and the remaining two-thirds were managed by lateral pinning configuration. Similar results were obtained in the two groups with no statistical difference regarding mayo elbow performance scores(mEPS) and Baumann angle. The mean mEPS in the lateral and crossed pinning groups were 93.68 + 8.59 and 93.62 + 9.05, respectively. The mean Baumann angle was 72.5° + 6.46 in the lateral group and 72.3° + 4.70 in the crossed-pinning group(P = 0.878).CONCLUSION Both lateral pinning and crossed pinning fixation configuration for displaced pediatric supracondylar humeral fractures provide similar functional and radiological outcomes.

In this work, Fourier-series representation of a discontinuous function is used to highlight and clarify the controversial problem of finding the value of the function at a point of discontinuity. Several physical situations are presented to examine the consequences of this kind of representation and its impact on some widely well-known problems whose results are not clearly understood or justified.

In this paper, charging capacitor in RC circuit, to a final voltage, via arbitrary number of steps, is investigated and analyzed both theoretically and experimentally. The obtained results show that the stored energy in the capacitor is constant independent of N, but the dissipated energy in the resistor and the consumed energy by the power supply decreases as number of steps N increases (adiabatic charging). The limit when the step number goes to infinity is examined and our result shows that the dissipated energy vanishes theoretically. This limit is carried out experimentally by using a ramp potential.

In this paper, we define the Weibull kernel and use it to nonparametric estimation of the probability density function (pdf) and the hazard rate function for independent and identically distributed (iid) data. The bias, variance and the optimal bandwidth of the proposed estimator are investigated. moreover, the asymptotic normality of the proposed estimator is investigated. The performance of the proposed estimator is tested using simulation study and real data.
