Background: s/Aims: Distal pancreatectomy with splenectomy (DPS) is a common surgical procedure for pancreatic body cancer.However, spleen-preserving distal pancreatectomy (SPDP) utilizing the Warshaw technique (WT) in malignancies is generally not favored due to concerns about inadequate resection. This study aims to assess the feasibility and oncologic outcomes of employing SPDP with WT in pancreatic body cancer. Methods: We conducted a retrospective analysis comparing 21 SPDP patients with 63 DPS patients matched by propensity score from January 2018 to November 2022. Clinical outcomes and follow-up data were analyzed using R. Results: Both groups exhibited similar demographic, intraoperative, and pathological characteristics, with the exception of a reduced number of total lymph nodes (p = 0.006) in the SPDP group. There were no significant differences in the rates of postoperative complications, recurrence, or metastasis. Local recurrence predominantly occurred in the central region as opposed to the spleen region.There were no cases of isolated recurrences in the splenic region. Median overall survival and recurrence-free survival times were 51.5 months for SPDP vs 30.5 months for DPS and 18.7 months vs 16.8 months, respectively (p > 0.05). The incidence of partial splenic infarction and left-side portal hypertension in the SPDP group was 28.6% (6/21) and 9.5% (2/21), respectively, without necessitating splenic abscess puncture, splenectomy, or causing bleeding from perigastric varices. Conclusions SPDP did not negatively impact local recurrence or survival rates in selected pancreatic body cancer patients. Further studies are necessary for validation.

ObjectiveTo investigate the mechanism by which Feixin decoction treats hypoxic pulmonary hypertension （HPH） by regulating the peroxisome proliferator-activated receptor gamma （PPARγ）/nuclear factor-kappa B （NF-κB）/NOD-like receptor pyrin domain containing 3 （NLRP3） signaling pathway. MethodsForty-eight male SD rats were randomly allocated into normal， hypoxia， and low-， medium- and high-dose （5.85， 11.7， 23.4 g·kg^-1， respectively） Feixin decoction groups， with 8 rats in each group. Except the normal group， the remaining five groups were placed in a hypoxia chamber with an oxygen concentration of （10.0±0.5）% for 8 h per day， 28 days， and administrated with corresponding drugs during the modeling process. After 4 weeks of treatment， echocardiographic parameters ［pulmonary artery acceleration time （PAT）， pulmonary artery ejection time （PET）， right ventricular anterior wall thickness （RVAWd）， and tricuspid annular plane systolic excursion （TAPSE）］ were measured for each group. The right ventricular systolic pressure （RVSP） was measured by the right heart catheterization method， and the right ventricular hypertrophy index （RVHI） was calculated by weighing the heart. The pathological changes in pulmonary arterioles were observed by hematoxylin-eosin staining. The co-localization of α-smooth muscle actin （α-SMA） with NLRP3， N-terminal gasdermin D （N-GSDMD）， and cysteinyl aspartate-specific proteinase-1 （Caspase-1） in pulmonary arteries was detected by immunofluorescence. The protein levels of PPARγ， NF-κB， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， N-GSDMD， interleukin-1β （IL-1β）， interleukin-18（IL-18）， and cleaved Caspase-1 in the lung tissue was determined by Western blot. The ultrastructural changes in pulmonary artery smooth muscle cells （PASMCs） were observed by transmission electron microscopy. ResultsCompared with the normal group， the hypoxia group showed increased RVSP and RVHI （P<0.01）， decreased right heart function （P<0.01）， increased pulmonary vascular remodeling （P<0.01）， increased co-localization of α-SMA with NLRP3， N-GSDMD， and Caspase-1 in pulmonary arterioles （P<0.01）， up-regulated protein levels of NF-κB， NLRP3， ASC， N-GSDMD， IL-1β， IL-18， and cleaved Caspase-1 in the lung tissue （P<0.05， P<0.01）， a down-regulated protein level of PPARγ （P<0.05， P<0.01）， and pyroptosis in PASMCs. Compared with the hypoxia group， Feixin decoction reduced RVSP and RVHI， improved the right heart function and ameliorated pulmonary vascular remodeling （P<0.05， P<0.01）， decreased the co-localization of α-SMA with NLRP3， N-GSDMD， and Caspase-1 （P<0.05， P<0.01）， down-regulated the protein levels of NF-κB， NLRP3， ASC， N-GSDMD， IL-1β， IL-18， and cleaved Caspase-1 in the lung tissue （P<0.05， P<0.01）， up-regulated the protein level of PPARγ （P<0.05， P<0.01）， and alleviated pyroptosis in PASMCs. ConclusionFeixin decoction can ameliorate pulmonary vascular remodeling and right heart dysfunction in chronically induced HPH rats by regulating pyroptosis in PASMCs through the PPARγ/NF-κB/NLRP3 pathway.

This paper reports a case of a patient with sleep-related painful erections treated by acupuncture combined with abdominal vibration therapy. The main symptom was repeated painful penile erections during nighttime sleep. The syndrome was differentiated as "water failing to nourish wood" and "liver qi stagnation". Acupuncture was applied at Baihui (GV20), Sishencong (EX-HN1), Guanyuan (CV4), and bilateral Neiguan (PC6), Hegu (LI4), Taichong (LR3), Taixi (KI3), Guilai (ST29), Yongquan (KI1), Yanglingquan (GB34), and Sanyinjiao (SP6). The treatment was combined with abdominal vibration therapy. Treatment was given once daily, five times per week. After the first treatment, the severity and duration of nocturnal erection pain were reduced, and sleep quality was improved. After two weeks of treatment, nocturnal erection pain persisted but became tolerable, with significantly shortened duration.

BACKGROUND: To evaluate the efficacy and safety of the first cohort of people in China treated with a responsive neurostimulation system (Epilcure TM , GenLight MedTech, Hangzhou, China) for focal drug-resistant epilepsy in this study. METHODS: This multicenter, before-and-after self-controlled study was conducted across 8 centers from March 2022 to June 2023, involving patients with drug-resistant epilepsy who were undergoing responsive neurostimulation (RNS). The study was based on an ongoing multi-center, single-blind, randomized controlled study. Efficacy was assessed through metrics including median seizure count, seizure frequency reduction (SFR), and response rate. Multivariable linear regression analysis was conducted to explore the relationships of basic clinical factors and intracranial electrophysiological characteristics with SFR. The postoperative quality of life, cognitive function, depression, and anxiety were evaluated as well. RESULTS: The follow-up period for the 19 participants was 10.7 ± 3.4 months. Seizure counts decreased significantly 6 months after device activation, with median SFR of 48% at the 6th month (M6) and 58% at M12 ( P  <0.05). The average response rate after 13 months of treatment was 42%, with 21% ( n  = 4) of the participants achieving seizure freedom. Patients who have previously undergone resective surgery appear to achieve better therapeutic outcomes at M11, M12 and M13 ( β  <0, P  <0.05). No statistically significant differences were observed in patients' scores of quality of life, cognition, depression and anxiety following stimulation when compared to baseline measurements. No serious adverse events related to the devices were observed. CONCLUSIONS: The preliminary findings suggest that Epilcure TM exhibits promising therapeutic potential in reducing the frequency of epileptic seizures. However, to further validate its efficacy, larger-scale randomized controlled trials are required. REGISTRATION Chinese Clinical Trial Registry (No. ChiCTR2200055247).

Bone is a highly calcified and vascularized tissue. The vascular system plays a vital role in supporting bone growth and repair, such as the provision of nutrients, growth factors, and metabolic waste transfer. Moreover, the additional functions of the bone vasculature, such as the secretion of various factors and the regulation of bone-related signaling pathways, are essential for maintaining bone health. In the bone microenvironment, bone tissue cells play a critical role in regulating angiogenesis, including osteoblasts, bone marrow mesenchymal stem cells (BMSCs), and osteoclasts. Osteogenesis and bone angiogenesis are closely linked. The decrease in osteogenesis and bone angiogenesis caused by aging leads to osteoporosis. Long noncoding RNAs (lncRNAs) are involved in various physiological processes, including osteogenesis and angiogenesis. Recent studies have shown that lncRNAs could mediate the crosstalk between angiogenesis and osteogenesis. However, the mechanism by which lncRNAs regulate angiogenesis‒osteogenesis crosstalk remains unclear. In this review, we describe in detail the ways in which lncRNAs regulate the crosstalk between osteogenesis and angiogenesis to promote bone health, aiming to provide new directions for the study of the mechanism by which lncRNAs regulate bone metabolism.

Acute ischemic stroke (AIS) is a cerebrovascular disease characterized by high morbidity, disability, and mortality, posing a significant threat to human health. Endovascular treatment has now been established as a key method for AIS management, in which stent retrievers that can mechanically remove blood clots play a key role in this technique. In recent years, stent retrievers have evolved in complexity and functionality to improve the ability of clot removing and surgical safety. However, the present instruments still have limitations on treatment efficiency, vascular adaptability, and operational precision, posing an urgent need for innovation in the design of stent retrievers. This paper systematically reviewed the structural features and working principles of AIS stent retrievers from the perspective of efficacy evaluation metrics, historical development, recent advancements in stent retrieval technology, and future prospects.
