This study explores whether the current external quality assessment (EQA) level and acceptable bias for basic semen analysis in China are clinically useful. We collected data of semen EQA from Andrology laboratories in the Hunan Province (China) in 2022 and searched for data in the published literature from January 2000 to December 2023 in China. On the basis of these data, we analyzed the coefficients of variation and acceptable biases of different quality control materials for basic semen analysis through robust statistics. We compared these findings with quality specifications based on biological variation from optimal, desirable, and minimum levels of bias to seek a unified and more suitable semen EQA bias evaluation standard for China's national conditions. Different sources of semen quality control material exhibited considerable variation in acceptable biases among laboratories, ranging from 8.2% to 56.9%. A total of 50.0% of the laboratories met the minimum quality specifications for progressive motility (PR), whereas 100.0% and 75.0% of laboratories met only the minimum quality specifications for sperm concentration and total motility (nonprogressive [NP] + PR), respectively. The Z value for sperm concentration and PR+NP was equivalent to the desirable performance specification, whereas the Z value for PR was equivalent only to the minimum performance specification. This study highlights the feasibility of operating external quality assessment schemes for basic semen analysis using quality specifications based on biological variation. These specifications should be unified among external quality control (EQC) centers based on biological variation.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

This study employed Mendelian randomization (MR) analysis to confirm the association between breast cancer and the risk of anxiety and depression, and to explore the molecular mechanisms by which lipid nanoparticles of ketamine (LNP@Ket) modulate these behaviors in a mouse model of breast cancer. Through single-cell transcriptomic analysis, the study aimed to clarify nuclear factor erythroid 2-related factor 2 (Nrf2)'s role in the development of anxiety and depression in these mice. Analysis of patient data from genome-wide association study (GWAS) databases supported the link between breast cancer, anxiety, and depression. In vivo experiments demonstrated that treating breast cancer mice with LNP@Ket significantly reduced anxiety and depression behaviors. The synthesis of LNP@Ket and its subsequent analysis highlighted its inhibitory effects on these behaviors. Single-cell transcriptomic sequencing identified key cells and genes affected by LNP@Ket treatment, particularly emphasizing Nrf2. Upregulation of Nrf2 in astrocytes increased the expression of antioxidant enzymes and reduced pro-inflammatory cytokines, alleviating anxiety and depression symptoms by inhibiting neuroinflammation and neurodegeneration. This comprehensive study highlights the pivotal role of Nrf2 in the therapeutic efficacy of LNP@Ket for treating anxiety and depression in breast cancer mice.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective : To investigate the expression of LncRNA PXN-AS1(abbreviated as PXN-AS1) in gastric cancer tissues and its impact on the proliferation, apoptosis, and invasion of gastric cancer cells, and to explore its potential regulatory mechanisms. Methods : Gastric cancer tissues and adjacent tissues from 43 patients with gastric cancer were collected. The expression levels of PXN-AS1 and miR-125a-5p in gastric cancer tissues were detected using qRT-PCR, and the relationship between the expression level of PXN-AS1 and the clinical pathological parameters of patients with gastric cancer was analyzed. Pearson correlation analysis was conducted to evaluate the correlation between PXN-AS1 and miR-125a-5p in gastric cancer tissues. PXN-AS1 siRNA plasmid(si-PXN-AS1) and negative control plasmid(si-NC), as well as miR-125a-5p inhibitor(inhibitor) and negative control miRNA inhibitor(inhibitor NC), were transfected alone or in combination into HGC-27 cells. The cells were divided into si-NC group, si-PXN-AS1 group, si-PXN-AS1+inhibitor NC group, si-PXN-AS1+inhibitor group, and a blank control group was also established. qRT-PCR was utilized to assess the expression levels of PXN-AS1 and miR-125a-5p in each cell group. CCK-8 assay was employed to evaluate the proliferation levels of cells in each group. EdU experiment was conducted to assess the proliferation status of cells in each group. Transwell assay was performed to examine the migration and invasion capabilities of cells in each group; flow cytometry was employed to measure the apoptosis levels of cells in each group; the dual-luciferase reporter gene system was used to validate the sponge absorption of PXN-AS1 on miR-125a-5p and regulate its expression levels. Bioinformatics analysis was employed to screen downstream target genes of miR-125a-5p and perform GO and KEGG enrichment analysis. Results : Compared with adjacent cancerous tissues, the expression level of the PXN-AS1 in gastric cancer tissues significantly increased, while the expression level of miR-125a-5p markedly decreased(bothP<0.05). PXN-AS1 and miR-125a-5p exhibited a negative correlation(r=-0.452,P=0.002). Furthermore, gastric cancer patients with high expression of PXN-AS1 exhibited the proportions of lymph node metastasis positivity and low differentiation were significantly higher(allP<0.05). Compared to the blank group and si-NC group, the si-PXN-AS1 group of HGC-27 cells showed significantly reduced levels of PXN-AS1 expression, cell proliferation capacity, and the number of cell migration and invasion(allP<0.05), while the level of cell apoptosis significantly increased(P<0.05). The dual-luciferase reporter system results demonstrated specific adsorption of miR-125a-5p by PXN-AS1 in HGC-27 cells. Knockdown of miR-125a-5p could reverse the effect of PXN-AS1 silencing on the inhibition of proliferation, migration and invasion of gastric cancer cells, and promote apoptosis. The bioinformatics analysis results indicated that the downstream target genes of miR-125a-5p were involved in various biological processes, including DNA damage, T cell apoptosis and differentiation, RNA metabolism synthesis processes, and signal transduction. Additionally, miR-125a-5p was implicated in signaling pathways such as the HIF-1 pathway, JAK-STAT pathway, and cell apoptosis signaling pathway. Conclusion PXN-AS1 is upregulated in gastric cancer. Moreover, acting as a competitive sponge for miR-125a-5p, PXN-AS1 promotes the proliferation, migration, and invasion abilities of gastric cancer cells HGC-27 while inhibiting apoptosis.

Objective:To investigate the safety and efficacy of pseudomonas aeruginosa Injection (PAI) in the treatment of coeliac leakage after cervical lymph node dissection for robotic thyroid cancer.Methods:Retrospective analysis of 1262 patients who underwent robotic thyroid surgery at the 960th Hospital of the People’s Liberation Army from Jan. 2021 to Aug. 2023 was made. Postoperative celiac leakage happened in 28 patients. The control and injection groups were divided according to whether pseudomonas aeruginosa injection was used or not. In the control group, there were 4 males and 11 females out of 15 patients, with an average age of (46.20±9.02) years old, and the treatment methods of low-fat diet, negative pressure suction, and pressure bandage were used. In the injection group, there were 7 males and 6 females among 13 patients, with an average age of (41.00±8.87) years. They were treated with low-fat diet, negative pressure suction, pressure bandage, and PAI .The number of lymph node dissection, total drainage volume, peak drainage volume, days of hospitalization and the rate of decline in drainage volume within 24 h after the use of PAI in the injection group, post-injection temperature, number of injections, and post-injection extubation time were statistically analyzed in both groups. Independent samples t test, Mann-Whitney U test, χ2 test or Fisher’s exact test were used for comparison between groups. Results:There was no statistically significant difference in age, gender, extent of thyroidectomy, highest daily drainage volume, and total drainage volume between the two groups ( P>0.05). The difference in the number of lymph node dissection (49.15±23.05 vs. 30.80±11.76, P=0.012) and hospitalization time (11.77±4.64 vs. 16.40±6.42, P=0.041) between the injection group and the control group was statistically significant. After the use of pseudomonas aeruginosa injection, the draining fluid decreased from the previous day (69.56± 20.82) % in the injection group; Twelve patients were successfully extubated after one injection of pseudomonas aeruginosa injection, and one patient was successfully extubated after two injections; the mean time to extubation after injection was (3.85±1.28) days; 76.9% patients (10/13) had fever symptoms within 48 h with body temperature (38.05±0.89) ℃ after injection, body temperature returned to normal after symptomatic treatment,and no other adverse reactions occurred except fever. Conclusion:Pseudomonas aeruginosa injection is safe and effective in the treatment of celiac leakage after cervical lymph node dissection for robotic thyroid cancer, effectively reducing cervical drainage and shortening hospitalization days.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.
