1.The Profound Significance of Pre-Qin Confucian Bioethics and its Revelation for Modern Bioethics
Chinese Medical Ethics 1995;0(03):-
Owning its unique and complete ideological system,Pre-Qin Confucian Bioethics includes the life value of "respect life and cherish materials",the life &death value of "cheer for life and grieve over death",and the health preservation value of "cultivate oneself to make progress".Pre-Qin Confucian Bioethics clarifies the very nature of life and utmost pursuit,and also sets up a norm of ethical options and fundamental approach to pursuing self life quality and health in a practical angle.Therefore,it is of great revealing significance for the formation of a scientific bioethical value.
2.Research advances in the mechanism of blood-brain barrier disruption by lipopolysaccharide and the onset of sepsis-associated encephalopathy
Journal of Apoplexy and Nervous Diseases 2024;41(1):77-83
As a barrier structure at the junction of the central nervous system (CNS) and the peripheral environment, the blood-brain barrier (BBB) successfully separates the circulating blood in brain tissue from the CNS and strictly controls material exchange between circulating blood and brain tissue, such as the transport of nutrients and the expulsion of metabolic wastes, thereby maintaining the homeostasis of the CNS. Lipopolysaccharide (LPS) is a component of the cell wall of Gram-negative bacteria and can impair the barrier function of the BBB and further promote the development and progression of sepsis-associated encephalopathy (SAE). This article reviews the mechanisms by which LPS injures the BBB via central links and other indirect links, as well as the association between these processes and SAE. We believe that when LPS causes damage to the BBB, a large number of immune cells and inflammatory factors enter brain tissue and activate immune cells of the brain, and even the neurovascular units that make up the BBB are affected and mediate the responses such as partial neuroinflammatory response and oxidative stress response, which causes further damage to the BBB. Such a vicious cycle eventually leads to the development of SAE, and therefore, we finally propose that targeted blockade of the disruption of BBB barrier function by LPS can be used for the prevention and treatment of SAE.

Objective:
Surgical procedures for patients with posttraumatic syringomyelia (PTS) remain controversial. Until now, there have been no effective quantitative evaluation methods to assist in selecting appropriate surgical plans before surgery.
Methods:
We consecutively enrolled PTS patients (arachnoid lysis group, n = 42; shunting group, n = 14) from 2003 to 2023. Additionally, 19 intrathecal anesthesia patients were included in the control group. All patients with PTS underwent physical and neurological examinations and spinal magnetic resonance imaging preoperatively, 3–12 months postoperatively and during the last follow-up. Preoperative lumbar puncture was performed and blood-spinal cord barrier disruption was detected by quotient of albumin (Qalb, cerebrospinal fluid/serum).
Results:
The ages (p = 0.324) and sex (p = 0.065) of the PTS and control groups did not differ significantly. There were also no significant differences in age (p = 0.216), routine blood data and prognosis (p = 0.399) between the arachnoid lysis and shunting groups. But the QAlb level of PTS patients was significantly higher than that of the control group (p < 0.001), and the shunting group had a significantly higher QAlb (p < 0.001) than the arachnoid lysis group. A high preoperative QAlb (odds ratio, 1.091; 95% confidence interval, 1.004–1.187; p = 0.041) was identified as the predictive factor for the shunting procedure, with the receiver operating characteristic curve showing 100% specificity and 80.95% sensitivity for patients with a QAlb > 12.67.
Conclusion
Preoperative QAlb is a significant predictive factor for the types of surgery. For PTS patients with a QAlb > 12.67, shunting represents the final recourse, necessitating the exploration and development of novel treatments for these patients.

Resection of oral and maxillofacial tumors is often accompanied by the inferior alveolar nerve neurectomy, resulting in abnormal sensation in lower lip. It is generally believed that spontaneous sensory recovery in this nerve injury is difficult. However, during our follow-up, patients with inferior alveolar nerve sacrifice showed different degrees of lower lip sensory recovery. In this study, a prospective cohort study was conducted to demonstrate this phenomenon and analyze the factors influencing sensory recovery. A mental nerve transection model of Thy1-YFP mice and tissue clearing technique were used to explore possible mechanisms in this process. Gene silencing and overexpression experiments were then conducted to detect the changes in cell morphology and molecular markers. In our follow-up, 75% of patients with unilateral inferior alveolar nerve neurectomy had complete sensory recovery of the lower lip 12 months postoperatively. Patients with younger age, malignant tumors, and preservation of ipsilateral buccal and lingual nerves had a shorter recovery time. The buccal nerve collateral sprouting compensation was observed in the lower lip tissue of Thy1-YFP mice. ApoD was demonstrated to be involved in axon growth and peripheral nerve sensory recovery in the animal model. TGF-β inhibited the expression of STAT3 and the transcription of ApoD in Schwann cells through Zfp423. Overall, after sacrificing the inferior alveolar nerve, the collateral compensation of the ipsilateral buccal nerve could innervate the sensation. And this process was regulated by TGF-β-Zfp423-ApoD pathway.
