Progress and Prospects of Surgical Treatment of Portal Hypertension

Journal of Biosciences and Medicines 2023年第11期11卷 170-180页

作者： linjun ruan Buqiang Wu Graduate School Changzhi Medical College Changzhi China Department of Hepatological Surgery Heping Hospital Affiliated to Changzhi Medical College Changzhi China

Portal hypertension is a group of syndrome characterized by splenic hyperfunction, esophageal and gastric varices and ascites caused by abnormal portal vein hemodynamics. Among them, upper gastrointestinal bleeding caused by esophageal and gastric varices is the most dangerous complication, which often threatens the lives of patients. After half a century of development, the treatment of portal hypertension is divided into two categories: medical drug therapy, endoscopic therapy and surgical treatment. With the understanding of portal hypertension and the continuous development of medical technology, the surgical operation of portal hypertension has also been greatly improved, reducing postoperative complications and improving the quality of life of patients after operation. However, at present, there is no surgical method that can completely cure portal hypertension. This article reviews the progress of surgical treatment of portal hypertension in recent years, in order to provide reference for the surgical treatment of portal hypertension.

Journal of Biosciences and Medicines 2024年第1期12卷 1-6页

作者： Haiying Cheng linjun ruan Nursing Department of Operating Room Tongji Hospital Affiliated to Tongji Medical College Huazhong University of Science and Technology Wuhan China Department of Hepatological Surgery Heping Hospital Affiliated to Changzhi Medical College Changzhi China

Objective: To explore the application value of rapid rehabilitation concept in patients with extrahepatic bile duct stones under laparoscopy during perioperative period. Methods: 90 patients with extrahepatic bile duct stones treated in our hospital from January 2022 to February 2023 were selected as the research object and randomly divided into the study group and the control group. The control group was given routine care, and the observation group was given rapid surgical rehabilitation care. The postoperative anal exhaust time, first meal time, early activity time, pain time, abdominal drainage tube removal time, hospitalization time and complication rate were compared between the two groups. The independent sample T test was used for the measurement data, and the x2 test was used for the counting data, and the difference was statistically significant (P Results: The postoperative anal exhaust time, first meal time, early activity time, pain time, abdominal drainage tube removal time and hospitalization time in the study group were shorter than those in the control group (all P Conclusion: The concept of rapid rehabilitation can significantly improve the perioperative nursing effect of patients with extrahepatic bile duct stones and accelerate their rehabilitation, which is worth improving and popularizing.

FGF8-mediated signaling regulates tooth developmental pace during odontogenesis

Journal of Genetics and Genomics 2022年第1期49卷 40-53页

The developing human and mouse teeth constitute an ideal model system to study the regulatory mechanism underlying organ growth control since their teeth share highly conserved and well-characterized developmental processes, and their developmental tempo varies notably. In the current study, we manipulated heterogenous recombination between human and mouse dental tissues and demonstrated that the dental mesenchyme dominates the tooth developmental tempo and FGF8 could be a critical player during this developmental process. Forced activation of FGF8 signaling in the dental mesenchyme of mice promoted cell proliferation, prevented cell apoptosis via p38 and perhaps PI3 K-Akt intracellular signaling,and impelled the transition of the cell cycle from G1-to S-phase in the tooth germ, resulting in the slowdown of the tooth developmental pace. Our results provide compelling evidence that extrinsic signals can profoundly affect tooth developmental tempo, and the dental mesenchymal FGF8 could be a pivotal factor in controlling the developmental pace in a non-cell-autonomous manner during mammalian odontogenesis.

系统级仿真中如何对电力电子接口电源降阶建模并分析其暂态稳定性成为新能源并网研究中亟待解决的难题。该文以蓄电池储能系统BESS为研究对象,根据电力电子接口特有的机电解耦原理解释这一类电源的准功率特性,并基于奇异摄动理论分析电源内部的精细时间尺度结构。据此,该文建立适应不同复杂度、精度要求的微分代数方程DAE降阶模型体系。在不同网侧外部扰动及电源内部参数配置的条件下验证降阶模型体系的有效性。模型可揭示具有准功率特性电源的暂态失稳模式,并保持电源外特性的模拟精度,计算出的暂态失稳临界指标满足实际需求。
