Article Synopsis
  • * Electrocatalysis and photocatalysis can synthesize ammonia under milder conditions, but their efficiency and scalability are not yet sufficient for industrial use, making thermal catalysis the most effective method currently.
  • * Recent advancements include developing new catalysts and exploring techniques like self-electron donation and anionic vacancy promotion to enhance nitrogen fixation and ammonia production efficiently, alongside addressing the challenges in further improving thermal catalytic processes.

Background: Primary vaginal cancer is rare and most vaginal tumors are metastatic, often arising from adjacent gynecologic structures. Primary vaginal cancers are also more common among postmenopausal women and most of these are squamous cell carcinomas, with adenocarcinomas being relatively rare. Vaginal bleeding is the most common clinical manifestation of vaginal adenocarcinoma.

Rare but critical bleeding events in primary immune thrombocytopenia (ITP) present life-threatening complications in patients with ITP, which severely affect their prognosis, quality of life, and treatment decisions. Although several studies have investigated the risk factors related to critical bleeding in ITP, large sample size data, consistent definitions, large-scale multicenter findings, and prediction models for critical bleeding events in patients with ITP are unavailable. For the first time, in this study, we applied the newly proposed critical ITP bleeding criteria by the International Society on Thrombosis and Hemostasis for large sample size data and developed the first machine learning (ML)-based online application for predict critical ITP bleeding.

Platinum-based chemotherapy is the primary treatment option for advanced non-small cell lung cancer (NSCLC) patients without a driver gene mutation, but its efficacy is still modest. Through a potential synergistic effect, autologous cellular immunotherapy (CIT) composed of cytokine-induced killer (CIK), natural killer (NK), and T cells might enhance it. NK cells exhibited in vitro cytotoxicity toward lung cancer cells (A549 cells) following platinum therapy.

Article Synopsis
  • The study investigates the role of key enzymes in glucose metabolism and glucose transporters in the bone marrow of patients with chronic mountain sickness (CMS) to understand the cause of erythrocytosis (increased red blood cell production).
  • It involved comparing 20 CMS patients with a control group and analyzing the mRNA and protein expressions of specific enzymes and transporters using various biochemical methods.
  • Results showed that CMS patients had higher levels of certain proteins related to glucose metabolism, particularly HK2, GLUT1, and GLUT2, which correlated positively with hemoglobin levels, suggesting a shift towards increased glycolysis to meet energy demands.

Background: Currently, there is no standard context that conforms to the Chinese national framework for evaluating medical decisions regarding the treatment of lung cancer.

Methods: This draft was formulated after a systematic review and a focus group discussion among 20 experts, who were senior physicians with extensive clinical experience from the Chinese Thoracic Oncology Group (CTONG) task force. Subsequently, a draft and a five-point Likert scale were sent to 300 CTONG working group members.

Introduction: Traditional cancer therapy has many disadvantages such as low selectivity and high toxicity of chemotherapy, as well as insufficient efficacy of targeted therapy. To enhance the cytotoxic effect and targeting ability, while reducing the toxicity of antitumor drugs, an antibody drug conjugate (ADC) was developed to deliver small molecular cytotoxic payloads directly to tumor cells by binding to specific antibodies via linkers.

Method: By reviewing published literature and the current progress of ADCs, we aimed to summarize the basic characteristics, clinical progress, and challenges of ADCs to provide a reference for clinical practice and further research.

Background: Scrub typhus, caused by Orientia tsutsugamushi, an obligate intracellular gram-negative bacterium, along with hemorrhagic fever with renal syndrome (HFRS), caused by hantaviruses, are natural-focus infectious diseases prevalent in Shandong Province, China. Both diseases have similar clinical manifestations in certain disease stages and similar epidemic seasons, which has caused difficulties for physicians in distinguishing them. The aim of this study was to investigate whether misdiagnosis of scrub typhus as HFRS occurred in patients in Shandong Province.

Objectives: Recent studies showed prolonged survival for advanced epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) patients treated with both monotherapies and combined therapies. However, high costs limit clinical applications. Thus, we conducted this cost-effectiveness analysis to explore an optimal first-line treatment for advanced EGFR-mutant NSCLC patients.

Electroacupuncture (EA) treatment in ischemic stroke has been highlighted recently; however, the specific mechanism is still elusive. Autophagy is considered a new target for cerebral ischemia/reperfusion (I/R), but whether it plays a role of protecting or causing rapid cell apoptosis remains unclear. Studies have reported that the reduction in lysine 16 of histone H4 acetylation coheres with autophagy induction.

Background: Despite the burgeoning literature describing preoperative and postoperative risks of a myasthenic crisis after thymectomy (MCAT) in patients with myasthenia gravis, substantial differences exist in the risk factors identified by previous studies. We conducted a meta-analysis to assess the reported risk factors and MCAT risk.

Methods: We collected relevant studies on the risk factors for MCAT by searching the PubMed, Embase, The Cochrane Library, China Biology Medicine (CBM), WanFang Data, VIP and CNKI databases.

Background Aims: The efficacy of CD19-targeted chimeric antigen receptor T (CAR T) cells for treatment of relapsed B-cell malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the long-term outcomes of these patients remain inconclusive.

Methods: The authors focused on the survival of 35 patients with B-cell acute lymphoblastic leukemia who relapsed after allo-HSCT and received CAR T cells.

Results: Of the 34 eligible patients, 30 achieved minimal residual disease-negative complete remission (CR), with a total CR rate of 85.

Graphyne, a theorized carbon allotrope possessing only sp- and sp -hybridized carbon atoms, holds great potentials in many fields, especially in catalysis and energy-transfer/storage devices. Using a bottom-up strategy, we synthesized a new N-doped graphyne analogue, triazine- and 1,4-diethynylbenzene-based graphyne TA-BGY, in solution in gram-scale. The unique sp/sp carbon-conjugated TA-BGY possesses an extended porous network structure with a BET surface area of approximately 300 m  g .

Despite extensive efforts, only three main strategies have been developed to synthesize covalent triazine-based frameworks (CTFs) thus far. We report herein a totally new synthetic strategy which allows C-C bonds in the CTFs to be formed through aromatic nucleophilic substitution reactions. The as-synthesized CTF-1 and CTF-2 exhibited photocatalytic water splitting activity comparable to the CTFs made using ionothermal or Brønsted acid-catalyzed polymerization.
