Periodontitis and rheumatoid arthritis (RA) are chronic inflammatory diseases that share similar inflammatory mechanisms and characteristics. Programmed cell death (PCD) has recently garnered attention for its crucial role in regulating inflammation and maintaining tissue homeostasis, as well as for its potential to link these two diseases. The various forms of PCD--including apoptosis, pyroptosis, and necroptosis--are closely controlled by signaling pathways such as Toll-like receptor 4 (TLR4) /NF-κB and MAPK. These pathways determine cell fate and influence inflammatory responses, tissue destruction, and repair, and they both play important roles in the pathogenesis of RA and periodontitis. In periodontitis, periodontal pathogens such as Porphyromonas gingivalis (P. gingivalis) and its virulence factors, including lipopolysaccharide (LPS), induce pyroptosis and necroptosis in immune cells such as macrophages via the TLR4/NF-κB pathway, which leads to an excessive release of pro-inflammatory cytokines such as interleukin (IL)-1β and tumor necrosis factor (TNF)-α. Concurrently, these pathogens inhibit the normal apoptotic process of immune cells, such as neutrophils, prolonging their survival, exacerbating immune imbalance, and aggravating periodontal tissue destruction. Similarly, in RA synovial tissue, fibroblast-like synoviocytes (FLS) acquire apoptosis resistance through signaling pathways such as the Bcl-2 family, JAK/STAT, and NF-κB, allowing for the consistent proliferation and secretion of matrix metalloproteinases and pro-inflammatory cytokines. Meanwhile, the continuous activation of pyroptotic pathways in neutrophils and macrophages results in the sustained release of IL-1β, further exacerbating synovial inflammation and bone destruction. Notably, dysregulated PCD fosters inter-organ crosstalk through shared inflammatory mediators and metabolic networks. Damage-associated molecular patterns (DAMPs) and cytokines that originate from periodontal lesions can spread systemically, influencing cell death processes in synovial and immune cells, thereby aggravating joint inflammation and bone erosion. By contrast, systemic inflammation in RA can upregulate osteoclastic activity or interfere with the normal apoptosis of periodontal cells via TNF-α and IL-6, ultimately intensifying periodontal immune imbalance. This review highlights the pivotal bridging role of PCD in the pathogenesis of both periodontitis and RA, providing a reference for therapeutic strategies that target cell death pathways to manage and potentially mitigate these diseases.

Objective:To explore the experience and needs of perioperative symptom management in lung cancer patients, so as to provide reference for further developing self-management interventions for symptom clusters in lung cancer patients.Methods:This study was descriptive and qualitative. From February to March 2023, purposive sampling was used to select 18 lung cancer patients who underwent surgery at the Shanghai Pulmonary Hospital Affiliated to Tongji University as the research subject, and semi-structured interviews were conducted on them. The thematic analysis method was used for data analysis.Results:Four themes were extracted, including the heavy burden of perioperative symptoms, the negative impact of symptom clusters on patients, obstacles to symptom management, and the need for symptom self-management.Conclusions:Lung cancer patients face various burdens during the perioperative period, causing serious distress to the patients. Patients have obstacles and different needs in symptom self-management. Medical and nursing staff should adopt targeted interventions and improvement strategies to enhance patient symptom self-management ability, reduce symptom burden, and improve quality of life.

Objective:To identify and observe disease-causing gene variants and clinical phenotypes in a Han Chinese family with Leber congenital amaurosis (LCA).Methods:A retrospective study. A patient with LCA10 and his parents who had presented at Department of Ophthalmology of Henan Provincial People's Hospital on May 2022 were selected as the study subject. Detailed medical and family histories were recorded, fundus photography and flash electroretinogram (F-ERG) were performed. Peripheral venous blood samples (3 ml) of the proband and his parents were collected to extract whole genomic DNA, then whole exome sequencing (WES) and mitochondrial DNA (mtDNA) sequencing were carried out for the proband to determine the disease-causing gene and variants. All variants were annotated by bioinformatics analysis. According to the American College of Medical Genetics and Genomics (ACMG) guidelines, the pathogenicity of all detected variants were evaluated. Candidate variants were verified by Sanger sequencing, and in vitro minigene assay were performed to evaluate the impact of the missense variant with insufficient evidence on mRNA splicing.Results:The proband, male, 7-month-old, presented with an inability to follow light or objects, eye poking, photophobia, nystagmus, partial loss of retinal pigment epithelium around the fovea of the macula. At the age of 2 years old, F-ERG revealed severe reduction, elongation, or even no waveform of a-wave and b-wave in both eyes. No obvious abnormality was found in the clinical phenotype of his parents. The result of WES revealed that the proband carried two variants in exon 40 and exon 2 of CEP290, a frameshift variant c.5515_5518del (p.Glu1839Lysfs*11) (V1) and a novel missense variant c.74C>T (p.Ala25Val) (V2), respectively. The result of mitochondrial DNA sequencing was negative. Sanger sequencing confirmed that the heterozygous frameshift variant was inherited from his father and the heterozygous novel missense variant was inherited from his mother, which constituted compound heterozygous variants. In vitro minigene splicing assay confirmed that V2 created a new splicing donor at exon 2, leading to the in-frame deletion of 30bp fragment during transcription and loss of 10 amino acid residues in the protein. The two variants were pathogenic (V1) and likely pathogenic (V2) based on ACMG guidelines, respectively. Conclusions:The c.5515_5518del and novel c.74C>T compound heterozygous variants of the CEP290 gene probably are the cause of LCA10 in this family, which lead to the production of a truncated protein and aberrant splicing of pre-mRNA, respectively. LCA is characterized by early onset, severe impairment of visual function, and a wide range of disease-causing variations.

ObjectiveTo investigate the role and possible mechanism of action of rhubarb decoction （RD） retention enema in improving inflammatory damage of brain tissue in a rat model of mild hepatic encephalopathy （MHE）. MethodsA total of 60 male Sprague-Dawley rats were divided into blank group （CON group with 6 rats） and chronic liver cirrhosis modeling group with 54 rats using the complete randomization method. After 12 weeks， 40 rats with successful modeling which were confirmed to meet the requirements for MHE model by the Morris water maze test were randomly divided into model group （MOD group）， lactulose group （LT group）， low-dose RD group （RD1 group）， middle-dose RD group （RD2 group）， and high-dose RD group （RD3 group）， with 8 rats in each group. The rats in the CON group and the MOD group were given retention enema with 2 mL of normal saline once a day； the rats in the LT group were given retention enema with 2 mL of lactulose at a dose of 22.5% once a day； the rats in the RD1， RD2， and RD3 groups were given retention enema with 2 mL RD at a dose of 2.5， 5.0， and 7.5 g/kg， respectively， once a day. After 10 days of treatment， the Morris water maze test was performed to analyze the spatial learning and memory abilities of rats. The rats were analyzed from the following aspects： behavioral status； the serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） and the level of blood ammonia； pathological changes of liver tissue and brain tissue； the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （AKT）， and mammalian target of rapamycin （mTOR） in brain tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the MOD group， the RD1， RD2， and RD3 groups had a significantly shorter escape latency （all P<0.01）， significant reductions in the levels of ALT， AST， IL-1β， IL-6， TNF-α， and blood ammonia （all P<0.05）， significant alleviation of the degeneration， necrosis， and inflammation of hepatocytes and brain cells， and significant reductions in the mRNA and protein expression levels of PI3K， AKT， and mTOR in brain tissue （all P<0.05）， and the RD3 group had a better treatment outcome than the RD1 and RD2 groups. ConclusionRetention enema with RD can improve cognitive function and inflammatory damage of brain tissue in MHE rats， possibly by regulating the PI3K/AKT/mTOR signaling pathway.

Objective: To investigate the causal relationship between gut microbiota and polycystic ovary syndrome (PCOS) using a Mendelian randomization (MR) study, so as to provide insights into the pathogenesis of PCOS and the formulation of prevention and treatment strategies. Methods: The genetic data on gut microbiota was derived from a meta-analysis of genome-wide association studies (GWAS) involving 18 340 participants. The genetic data on PCOS was sourced from two GWAS meta-analyses in European populations, serving as the discovery set and the validation set, respectively. A two-sample MR analysis was conducted using the discovery set, with the inverse variance weighted (IVW) method as the primary approach. Sensitivity analyses employed the weighted median method, MR-Egger regression, and the MR-PRESSO test. The validation set was utilized for verification, and a meta-analysis was performed to combine the results from the two datasets. Results: Forward MR analysis results showed that nine types of gut microbiota were statistically associated with PCOS (all P<0.05). Specifically, the association of family Streptococcaceae (OR=1.442, 95%CI: 1.097-1.895), genus Actinomyces (OR=1.359, 95%CI: 1.036-1.784), genus Ruminococcaceae UCG 011 (OR=0.755, 95%CI: 0.619-0.921), genus Sellimonas (OR=0.766, 95%CI: 0.657-0.893) and genus Streptococcus with PCOS (OR=1.496, 95%CI: 1.136-1.972) remained consistent in the sensitivity analysis. Reverse MR analysis showed no evidence for the causal association between PCOS and the aforementioned five types of gut microbiota (all P>0.05). The MR analysis results of the validation set showed that there was no statistical association between the aforementioned five types of gut microbiota and PCOS (all P>0.05). However, the associations remained significant for genus Actinomyces (OR=1.226,95%CI：1.010-1.503) and genus Streptococcus (OR=1.266,95%CI：1.042-1.452) in the meta-analysis (both P<0.05). Conclusion This study provides the evidence that genus Actinomyces and genus Streptococcus are causally associated with PCOS.

Objective: To examine the association between sleep and frailty using the bidirectional two-sample Mendelian randomization (MR) approach, so as to provide the basis for the prevention and intervention of frailty. Methods: The data on single nucleotide polymorphisms (SNP) related to sleep duration, insomnia and morning chronotype were collected from genome-wide association studies (GWAS) and meta-analysis of GWAS, involving 446 118, 1 331 010 and 697 828 participants, respectively. The frailty was evaluated using the frailty index, and the relevant SNP data were collected from a meta-analysis of GWAS involving 175 226 participants. A bidirectional MR analysis was performed using the inverse-variance weighted method. Sensitivity analyses employed the weighted median method, the maximum likelihood-based method, the MR-Egger regression, and the MR-PRESSO test. Results: Forward MR analysis showed that longer sleep duration (β=-0.170, 95%CI: -0.255 to -0.085) and morning chronotype (β=-0.036, 95%CI: -0.058 to -0.014) decreased the risk of frailty, while insomnia increased the risk of frailty (β=0.167, 95%CI: 0.149-0.184). Reverse MR analysis showed that frailty increased the risk of insomnia (OR=1.645, 95%CI: 1.278-2.117). Both bidirectional MR results were robust, which excluded the impact of heterogeneity and horizontal pleiotropy. Conclusion Sleep duration, insomnia, and morning chronotype are associated with frailty.

The Wnt signaling pathway plays an important role in maintaining liver homeostasis and liver regeneration.In healthy livers,the Wnt signaling pathway is mostly inactive,but it is continuously overactivated during cell renewal or regeneration processes,as well as in certain pathological conditions,diseases,precancerous states,and cancers.Persistent liver cell injury often leads to chronic liver diseases such as liver fibrosis,liver cirrhosis,and liver cancer.This article summarizes the basic structural features of the Wnt signaling pathway and analyzes its important role in the pathological progression of various liver diseases,so as to provide new ideas for the prevention and treatment of liver diseases in clinical practice.

Objective:To understand the current status of kidney transplant patient empowerment and explore the factors affecting kidney transplant patient empowerment.Methods:This study was a cross-sectional survey. From September to November 2022, convenience sampling was used to select 201 patients who were followed up by the Renal Transplantation Department of Shanghai General Hospital as the study subject. A survey was conducted using the Patient General Information Questionnaire, Client Empowerment Scale (CES), General Self-Efficacy Scale (GSES), Nurse-Patient Trust Scale, and Chinese Version of Chronic Illness Resource Survey (CV-CIRS). Multiple linear regression analysis was used to explore the influencing factors of empowerment levels in kidney transplant patients.Results:A total of 201 questionnaires were distributed and 197 valid questionnaires were collected, with an effective recovery rate of 98.01% (197/201). The total empowerment score of 197 kidney transplant patients was (161.85±13.08). Multiple linear regression analysis showed that willingness to participate in health decision-making, general self-efficacy, and chronic disease resource support were the influencing factors for kidney transplant patient empowerment ( P<0.05) . Conclusions:The empowerment of kidney transplant patients is at a moderate to upper level. The willingness of patients to participate in health decision-making, general self-efficacy, and chronic disease resource support are influencing factors for kidney transplant patient empowerment.

Objective:To explore the predictive value of 18F-FDG PET/CT metabolic parameters combined with inflammatory markers for the medium-term efficacy of chemotherapy in patients with primary gastrointestinal diffuse large B cell lymphoma (PGI-DLBCL). Methods:From April 2011 to May 2020, 67 patients (37 males, 30 females, age: 28-85 years) with PGI-DLBCL examined by 18F-FDG PET/CT before chemotherapy in Changhai Hospital, Navy Medical University were retrospectively analyzed. All patients were treated with cyclophosphamide+ doxorubicin+ vincristine+ prednisone (CHOP) or rituximab+ CHOP (R-CHOP) regimens, and the medium-term efficacy was evaluated after 2-4 cycles of chemotherapy. The effect outcome was divided into complete remission (CR) group and non-CR (NCR) group based on the Lugano lymphoma response evaluation criteria. Mann-Whitney U test was used to compare the differences of SUV max, peak of SUV (SUV peak), metabolic tumor volume (MTV), total lesion glycolysis (TLG), platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR) between two groups. The independent risk factors of NCR were analyzed by multivariate logistic regression and the binary logistic regression model was established according to the results. The model was tested with external validation data ( n=15). Results:Of 67 PGI-DLBCL patients, 28(41.8%) were CR and 39(58.2%) were NCR. SUV peak, MTV, TLG, PLR and NLR in NCR group (17.3(12.3, 28.1), 73.8(42.9, 141.7) cm 3, 887.5(300.9, 2 075.3) g, 203.9(155.7, 297.1), 3.9(3.0, 4.9)) were significantly higher than those in CR group (9.5(6.2, 15.2), 11.3(4.7, 23.2) cm 3, 85.2(35.5, 214.6) g, 149.3(102.8, 173.1), 2.2(1.8, 4.6); z values: from -6.41 to -2.33, all P<0.05). The logistic regression model was as follows: P=1/(1+ e - x), x=0.100×MTV+ 0.024×PLR-8.064. The prediction accuracy for NCR risk was 86.57%(58/67), with the accuracy of 13/15 tested by external validation data. Conclusion:MTV combined with PLR has a good predictive value for medium-term efficacy of CHOP/R-CHOP chemotherapy in patients with PGI-DLBCL.
