Pulmonary lymphangioleiomyomatosis is a rare disease characterized by the abnormal proliferation of pulmonary lymphatic smooth muscle cells. It is common in women and often accompanied by recurrent pneumothorax, chylothorax and progressive dyspnea, imaging characterized by diffuse cystic lesions in both lungs. Pulmonary lymphangioleiomyomatosis progresses aggressively and has a very poor prognosis, with a lack of effective medical treatment options in the advanced stages. Lung transplantation is a safe and effective method for the treatment of advanced pulmonary lymphangioleiomyomatosis, which may significantly improve the survival rate and quality of life of patients. The median survival period after surgery can reach 12 years. This article reviews the pathogenesis, diagnosis, treatment of pulmonary lymphangioleiomyomatosis, and the current status and existing problems of lung transplantation in pulmonary lymphangioleiomyomatosis, aiming to provide a reference for the clinical treatment and subsequent research of pulmonary lymphangioleiomyomatosis.

Objective:To report the 5-year survival outcomes and recurrence patterns of robotic total gastrectomy (RTG) for locally advanced proximal gastric cancer in order to provide more valuable long-term follow-up results for clinical practice.Methods:This was a prospective, single-arm, open-label clinical trial (FUGES-014; Clinical-Trials.gov, NCT03524287). Patients with locally advanced proximal gastric cancer who underwent RTG at Fujian Medical University Union Hospital from March 5, 2018, to February 10, 2020, were included in the analysis. To evaluate the long-term efficacy of RTG in the most objective manner possible, we performed a propensity score-matched (1∶2) comparative analysis with historical control patients who had undergone laparoscopic total gastrectomy (LTG) from the FUGES-002 study (ClinicalTrials.gov, NCT02333721) in which the 5-year disease-free survival (DFS), 5-year overall survival (OS), and recurrence patterns were compared between the two groups.Results:Prior to matching, there were 48 cases in the RTG group and 263 cases in the LTG group; patients in the LTG group had more advanced cT and pT stages ( P=0.044 and 0.006, respectively) compared to the RTG group. After matching, there were 48 cases in the RTG group and 96 cases in the LTG group; however, no statistically significant differences were observed in the baseline clinical characteristics between the two groups (all P>0.05). Both groups had a median follow-up of 72 months. The 5-year DFS rates were 75.0% (95%CI: 63.7%- 88.3%) in the RTG group and 61.4% (95%CI: 52.5%-72.0%) in the LTG group ( P=0.116). Similarly, the 5-year OS rates were 79.2% (95%CI: 68.5%-91.5%) and 64.6% (95%CI: 55.7%-74.9%) in the RTG and LTG groups, respectively ( P=0.100). Within 5 years after surgery, tumor recurrence occurred in 10 patients (20.8%) in the RTG group and 33 patients (34.4%) in the LTG group ( P=0.124), and peritoneal recurrence was the predominant pattern in both groups (8.3%[4/48] vs. 10.4%[10/96]; risk difference: -0.02, P=0.554). Gastric cancer-related death was the predominant cause of death in both groups (16.7% [8/48] vs. 31.2% [30/96]; risk difference: -0.15, P=0.064). Among patients stratified by different pathological stages, no statistically significant differences were found in DFS, OS, or recurrence rates between the RTG and LTG groups (all P>0.05). Conclusions:We find the long-term oncological outcomes of RTG for locally advanced proximal gastric cancer to be noninferior to those of LTG. RTG should therefore be considered as a valid option for standardized minimally invasive surgery for locally advanced proximal gastric cancer.

Objective:To conduct a scoping review on self-transcendence in cancer patients, analyze and summarize the current status of self-transcendence in cancer patients, so as to provide a reference for its future development in cancer.Methods:The relevant research was systematically searched on China National Knowledge Infrastructure, WanFang Data, VIP, PubMed, Web of Science, Embase, Cochrane Library, and CINAHL, with a search period from database establishment to September 5, 2023. The included literature was summarized and analyzed.Results:A total of 43 articles were included, consisting of 16 cross-sectional surveys, 8 qualitative studies, and 19 intervention studies. Five aspects were elaborated and summarized, namely theoretical evolution and development, evaluation tools, current situation and influencing factors, implementation approaches, and intervention program characteristics.Conclusions:The research on self-transcendence in cancer patients is in the ascendant. In the future, it is necessary to strengthen the development of self-transcendence assessment tools for cancer patients, adopt various research methods to comprehensively understand the changes in self-transcendence level and psychological experience of cancer patients, and improve the scientific and rigorous nature of self-transcendence intervention program for cancer patients.

Objective:Exploring the dilemmas faced by adolescents with type 1 diabetes mellitus in self-management during the transition to adult healthcare, to inform healthcare professionals in the delivery of transitional care interventions.Methods:Using descriptive qualitative research methods, in-depth interviews were conducted from August to December 2023 to adolescents with type 1 diabetes mellitus (selected by objective sampling) who met the inclusion and exclusion criteria in the Department of Endocrinology of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine and the Shenzhen Children′s Hospital, and the data were analysed inductively using directed content analysis.Results:A total of 12 adolescents with type 1 diabetes mellitus were included for interview, 6 males and 6 females, aged 12-18 years. The self-management dilemmas for adolescents with type 1 diabetes in the transition to adult healthcare can be summarised into 4 themes and 10 sub-themes: disease management dilemmas (weak awareness of disease management, insufficient disease-related knowledge and competence, low adherence to disease management, and restriction of daily activities), role adaptation difficulties (lack of perceived transition to the healthcare role, difficulty in transitioning to the family role, and maladaptation to the social role), negative emotions Inadequate social support system (lack of school support, limited accessibility of social organisations, insufficient socio-economic support).Conclusions:Adolescents with type 1 diabetes mellitus face multiple dilemmas in disease self-management during the transition to adult healthcare, and healthcare professionals should pay attention to transition self-management education, improve patients′ awareness of transition self-management and their ability to participate in it, formulate a transition preparation plan, build an emotional support network, and improve the social security system, so as to help juvenile patients with type 1 diabetes master the method of self-management and make a successful transition to adulthood.

Objective To identify the characteristics of complementary and alternative therapies for cancer patients and investigate the effect on symptom clusters in cancer patients,in order to provide references in management of the symptom clusters.Methods A scoping review was conducted to search nine databases,namely PubMed,Cochrane Library,Web of Science,Embase,PsycINFO,CINAHL,CNKI,Wanfang Data,and VIP,for literatures published between January 2016 and January 2024.Results Twenty articles focusing on complementary and alternative therapies were included.Four themes were identified from the retrieved articles:cancer research subjects,characteristics of complementary alternative therapies,type of symptom cluster and effectiveness of complementary alternative therapies.Specifically,the cancer research subjects in relation to symptom cluster management included those of breast cancer,advanced cancer and the cancer under radio or chemotherapy.The most commonly used types of complementary and alternative therapies in managing the symptom clusters were exercise therapies,cognitive-behavioural interventions,traditional Chinese medicine therapies,multidisciplinary collaborative models and specific interventions.Interventions for symptom clusters predominantly targeted fatigue,mental status,pain,and gastrointestinal symptoms.Conclusion The interventions for symptom clusters in complementary and alternative therapies vary across different types of complementary and alternative therapies,so as the effectiveness.Some of the complementary and alternative therapies have unidentified effects and further investigations are required.The complementary and alternative therapies currently that have been used in managing the symptom clusters were found to have shortcomings.Further studies should focus on sentinel and core symptoms of symptom clusters and emphasize the development of standardised and individualised intervention plans based on symptom management theories,hence to improve the management of symptom clusters in cancer patients.

ObjectiveTo investigate the effects of licoflavone A on the proliferation and glycolysis of gastric cancer cells in the hypoxic environment. MethodHuman gastric cancer AGS cells were classified into five groups： Normoxia， hypoxia， and low-， medium-， and high-dose （25， 50， 100 μmol·L^-1， respectively） licoflavone A. The cells in other groups except the normoxia group were cultured in the environment with 5% O₂ for 48 h. The cell counting kit-8 （CCK-8） and colony formation assay were employed to examine the proliferation of AGS cells. Cell migration was detected by the scratch assay. The protein and mRNA levels of hypoxia-inducible factor 1-alpha （HIF-1α）， glucose transporter 1 （GLUT1）， lactate dehydrogenase A （LDHA）， pyruvate kinase M2 （PKM2）， and hexokinase Ⅱ （HK2） in AGS cells were measured by Western blotting and real-time quantitative polymerase chain reaction （Real-time PCR）， respectively. The corresponding kits were used to determine glucose uptake and HK activity. ResultThe CCK-8 results showed that compared with the hypoxia group， the high- and medium-dose licoflavone A groups showed decreased proliferation rate of AGS cells at the time point of 24 h （P<0.01） and all the licoflavone A groups demonstrated decreased proliferation rate at the time point of 48 h （P<0.01）. Compared with the normoxia group， the hypoxia group showed increased number of clone formation of AGS cells （P<0.01）， which was decreased after the treatment with licoflavone A at high， medium， and low doses （P<0.01）. Compared with the normoxia group， the hypoxia group showed increased migration of AGS cells （P<0.01）， which was attenuated by the high， medium， and low doses of licoflavone A （P<0.01）. Compared with the normoxia group， the hypoxia group showed up-regulated mRNA levels of GLUT1， LDHA， PKM2， and HK2 （P<0.05， P<0.01）. Compared with those in the hypoxia group， the mRNA levels of GLUT1， LDHA， PKM2， and HK2 in the high-dose licoflavone A group， GLUT1， LDHA， and HK2 in the medium-dose licoflavone A group， and HK2 in the low-dose licoflavone A group were down-regulated （P<0.05， P<0.01）. The protein levels of HIF-1α， GLUT1， LDHA， PKM2， and HK2 in the hypoxia group were higher than those in the normoxia group （P<0.05， P<0.01）. Compared with those in the hypoxia group， the protein levels of HIF-1α， GLUT1， LDHA， PKM2， and HK2 in the high-dose licoflavone A group and HK2 in the medium- and low-dose licoflavone A groups were down-regulated （P<0.05， P<0.01）. The glucose uptake and HK activity were elevated in the hypoxia group compared with those in the normoxia group （P<0.01）. Compared with the hypoxia group， high-dose licoflavone A decreased the glucose uptake and HK activity， and medium-dose licoflavone A decreased the HK activity （P<0.01）. ConclusionLicoflavone A inhibits the proliferation of AGS cells under hypoxic conditions by regulating glycolysis in gastric cancer.

Mycobacterium neoaurum has the ability to produce steroidal intermediates known as 22-hydroxy-23, 24-bisnorchol-4-en-3-one (BA) upon the knockout of the genes for either the hydroxyacyl-CoA dehydrogenase (Hsd4A) or acyl-CoA thiolase (FadA5). In a previous study, we discovered a novel metabolite in the fermentation products when the fadA5 gene was deleted. This research aims to elucidate the metabolic pathway of this metabolite through structural identification, homologous sequence analysis of the fadA5 gene, phylogenetic tree analysis of M. neoaurum HGMS2, and gene knockout. Our findings revealed that the metabolite is a C23 metabolic intermediate, named 24-norchol-4-ene-3, 22-dione (designated as 3-OPD). It is formed when a thioesterase (TE) catalyzes the formation of a β-ketonic acid by removing CoA from the side chain of 3, 22-dioxo-25, 26-bisnorchol-4-ene-24-oyl CoA (22-O-BNC-CoA), followed by spontaneously undergoing decarboxylation. These results have the potential to contribute to the development of novel steroid intermediates.
