Five new flavan-4-ol glycosides jixueqiosides A-E (1-5) and two new flavan glycosides jixueqiosides F and G (6 and 7), along with twelve known flavan-4-ol glycosides (8-19), were isolated from the roots of Pronephrium penangianum. Comprehensive spectral analyses, X-ray single-crystal diffraction, and theoretical electronic circular dichroism (ECD) calculations established structures and absolute configurations. A single crystal structure of flavan-4-ol glycoside (14) was reported for the first time, while the characteristic ECD and NMR data for all isolated flavan-4-ol glycosides (1-5 , 8-19) were analyzed, establishing a set of empirical rules. Activity screening of these isolates showed that 8 and 9 could inhibit the proliferation of MDA-MB-231 and MCF-7 cells with IC50 values of 7.93 ? 2.85 ?mol?L-1 and 5.87 ? 1.58 ?mol?L-1 (MDA-MB-231), and 2.21 ? 1.38 ?mol?L-1 and 3.52 ? 1.55 ?mol?L-1 (MCF-7), respectively. Western blotting and flow cytometry analyses demonstrated that 8 and 9 dose-dependently induced apoptosis in MDA-MB-231 cells by up-regulating BAX, activating caspase-3 and down-regulating BCL-2. Additionally, compound 8 affected autophagy-related proteins, increasing the ratio of LC3-II/LC3-I and Beclin-1 levels to inhibit MDA-MB-231 cell proliferation. Moreover, anti-inflammatory studies indicated that 2, 3, 7, 13, 14, and 18 moderately inhibited tumor necrosis factor-a (TNF-a), interleukin-6 (IL-6), and nitric oxide (NO) release.

Pyroptosis, a form of inflammatory cell death mediated by the Gasdermins family, promotes the release of inflammatory mediators and activates immune cell populations such as NK cells, T cells and macrophages in the tumor microenvironment(TME) to exert immune-regulating and anti-tumor effects. Glioblastoma(GBM) is the most serious and malignant glioma, and the median survival of patients diagnosed with GBM is less than 2 years, and the presence of the blood-brain barrier makes it difficult to deliver drugs to the brain, thus affecting the effect of drugs against GBM. Therefore, it is important to explore new measures and mechanisms to treat GBM, which has a complex TME with a large number of immune cell populations that are often immunosuppressed by GBM. Cellular pyroptosis as a mode of cell death capable of activating immunity, has the effect of activating the body’s immunity to help reverse TME immunosuppression. This review will focus on the relationship between cell pyroptosis and the immune system, how cell pyroptosis affects the immune cell population of TME in GBM, and the new progress in drug research on cell pyroptosis pathways in GBM treatment, providing new directions and strategies for future clinical treatment of GBM.

Purpose:
The enhanced recovery after surgery (ERAS) protocol for radical cystectomy aims to facilitate postoperative recovery and hasten a return to normal daily activities. This study aims to report on the perioperative outcomes of implementation of an ERAS protocol at a single Australian institution.
Materials and Methods:
We identified 73 patients with pT1–T4 bladder cancer who underwent open radical cystectomy at Western Health, Victoria between June 2016 and August 2021. A retrospective analysis of a prospectively maintained database was performed. Perioperative outcomes included length of hospital stay, nasogastric tube requirement and duration of postoperative ileus.
Results:
The median age was 74 years (interquartile range [IQR] 66–78) for the ERAS group and 70 years (IQR 65–78) for the preERAS group patients. All patients in each group underwent ileal conduit formation. The median length of hospital stay was 7.0 days (IQR 7.0–9.3) for the ERAS group and 12.0 days (IQR 8.0–16.0) for the pre-ERAS group (p=0.003). Within the ERAS group, 25.0% had a postoperative ileus, and 25.0% had a nasogastric tube inserted, compared with 64.9% (p=0.001) and 45.9% (p=0.063) respectively within pre-ERAS group. The median bowel function recovery time, defined as duration from surgery to first bowel action, was 5.0 days (IQR 4.0–7.0) in the ERAS group and 7.5 days (IQR 5.0–8.5) in the pre-ERAS group (p=0.016).
Conclusions
Implementation of an ERAS protocol is associated with a reduction in hospital length of stay, postoperative ileus and bowel function recovery time.

Sarcopenia, which is characterized by progressive and generalized loss of skeletal muscle mass and strength, has been well described to be associated with numerous poor postoperative outcomes, such as increased perioperative mortality, postoperative sepsis, prolonged length of stay, increased cost of care, decreased functional outcome, and poorer oncological outcomes in cancer surgery. Multimodal prehabilitation, as a concept that involves boosting and optimizing the preoperative condition of a patient prior to the upcoming stressors of a surgical procedure, has the purported benefits of reversing the effects of sarcopenia, shortening hospitalization, improving the rate of return to bowel activity, reducing the costs of hospitalization, and improving quality of life. This review aims to present the current literature surrounding the concept of sarcopenia, its implications pertaining to colorectal cancer and surgery, a summary of studied multimodal prehabilitation interventions, and potential future advances in the management of sarcopenia.

Pediatric acute hyperextension spinal cord injury (SCI) named as PAHSCI by us, is a special type of thoracolumbar SCI without radiographic abnormality and highly related to back-bend in dance training, which has been increasingly reported. At present, it has become the leading cause of SCI in children, and brings a heavy social and economic burden. Both domestic and foreign academic institutions and dance education organizations lack a correct understanding of PAHSCI and relevant standards, specifications or guidelines. In order to provide standardized guidance, the expert team formulated this guideline based on the principles of science and practicability, starting from the diagnosis, differential diagnosis, etiology, admission evaluation, treatment, complications and prevention. This guideline puts forward 23 recommendations for 14 related issues.

The advantages of lymph node dissection through total laparoscopic total gastrectomy (TLTG) seem to be more and more accepted by the academic community. However, reconstruction of digestive tract is challenging and remains a focus of debate and research. Which way is better for esophagojejunostomy, circular stapler or linear stapler,remains to be answered. The authors believe that, under the conditions of existing anastomosis instruments, using of linear stapler for esophagojejunal side-to-side anastomosis may be the most common choice, but it must be used with strict indications, because there are still many problems to be solved. It is believed that with the breakthrough in the development of the circular stapler suitable for esophagojejunostomy in TLTG, the application of circular stapler for digestive tract reconstruction will become the mainstream again in future. Thus, the current routine clinical practice of TLTG should be cautious and the surgical indications should be strictly evaluated.
