Hepatocellular carcinoma (HCC) is one of the most malignant tumors with the highest incidence and mortality in the world, causing a serious burden on society. Pyruvate kinase M2 (PKM2) is one of the principal metabolic enzymes involved in glycolysis. Studies have shown that PKM2 is highly expressed in HCC and can be translocated to the nucleus, where it interacts with various transcription factors and proteins such as hypoxia-inducible factor-1α, sterol regulatory element-binding protein 1a, signal transducer and activator of transcription 3, nuclear factor erythroid 2-like 2 and histone H3, exerting non-metabolic enzyme functions to regulate the cell cycle, proliferation, apoptosis, immune escape, migration, and invasion, as well as HCC angiogenesis and tumor microenvironment. This review is focused on the recent progress of PKM2 interacting with various transcription factors and proteins affecting the onset and development of HCC, as well as natural drugs and noncoding RNA impacting diverse biological functions of liver cancer cells by regulating PKM2 non-metabolic enzyme functions, thereby providing valuable directions for the prognosis improvement and molecular targeted therapy of HCC in the future.

This study aimed to investigate the underlying mechanism of Zuogui Pill in its efficacy against liver cancer, employing a combination of data mining approaches and network pharmacology methods. A novel clustering analysis algorithm was proposed to identify the core gene modules of Zuogui Pill. This algorithm successfully identified 5 core modules, with the first large module comprised of twelve proteins forming a 12-clique, representing the strongest connections among them. ⋯ In summary, symptom-target associations are valuable in uncovering the underlying molecular mechanisms of Zuogui Pill. Our work reinforced the notion that Zuogui pill exhibits therapeutic potential on liver cancer through network targets, as well as synergistic effects of multi-component and multi-pathway. This study provided specific references for future experiments at the cost of less time.

There is an urgent need to find common targets for precision therapy, as there are no effective preventive therapeutic measures for combined clinical heart-brain organ protection and common pathways associated with glutamate receptors are involved in heart-brain injury, but current glutamate receptor-related clinical trials have failed. Ischemia-reperfusion injury (IRI) is a common pathological condition that occurs in multiple organs, including the heart and brain, and can lead to severe morbidity and mortality. ⋯ NMDAR activity is mainly regulated by endogenous activators, agonists, antagonists, and voltage-gated channels, and activation leads to excessive calcium influx, oxidative stress, mitochondrial dysfunction, inflammation, apoptosis, and necrosis in ischemic cells. In this review, we summarize current research advances regarding the role of NMDAR in myocardial and cerebral IRI and discuss potential therapeutic strategies to modulate NMDAR signaling to prevent and treat IRI.

Idiopathic intracranial hypertension (IIH) is a condition of unknown etiology that primarily affects obese women of childbearing age. Symptoms include disabling headaches, visual disturbances, and intracranial noises (pulsatile tinnitus). Currently, no standardized treatment guidelines are available and the current management focuses on weight loss and acetazolamide use. ⋯ Based on its varying mechanisms of action, topiramate is a strong potential treatment agent for IIH, yet acetazolamide is often chosen first-line. However, the data supporting use of acetazolamide or topiramate is inefficient to designate one agent preferred over the other. There is a need for further studies assessing topiramate use in the treatment of IIH, and comparing topiramate use to other treatment modalities.

Randomized Controlled Trial
General anesthesia versus combined interscalene nerve/superficial cervical plexus block in arthroscopic rotator cuff repair: A randomized prospective control trial.
In this study, interscalene brachial plexus block (ISB) with superficial cervical plexus block added and general anesthesia (GA) application were evaluated in terms of intraoperative hemodynamics, operative time and postoperative analgesia need in patients who underwent rotator cuff tear repair. ⋯ In rotator cuff tear repair anesthesia, ISB with superficial cervical plexus block provides adequate intraoperative anesthesia, low postoperative VAS level, reduced and deferred consumption of opioids and nonsteroidal anti-inflammatory drugs, higher patient and surgeon satisfaction and early discharge.
