BACKGROUND:At present,osteoarthritis has become a major disease affecting the quality of life of the elderly,and the therapeutic effect is poor,often focusing on preventing the disease process,and the pathogenesis of osteoarthritis is still not fully understood.Bioinformatics analysis was carried out to explore the main pathogenesis of osteoarthritis and related mechanisms of gene coding regulation. OBJECTIVE:To screen core differential genes with a major role in osteoarthritis by gene expression profiling. METHODS:Datasets were downloaded from the Gene Expression Omnibus(GEO):GSE114007,GSE117999,and GSE129147.Differential genes in the GSE114007 and GSE117999 data collections were screened using R software,performing differential genes to weighted gene co-expression network analysis.The module genes most relevant to osteoarthritis were selected to perform protein interaction analysis.Candidate core genes were selected using the cytocape software.The candidate core genes were subsequently subjected to least absolute shrinkage and selection operator regression and COX analysis to identify the core genes with a key role in osteoarthritis.The accuracy of the core genes was validated using an external dataset,GSE129147. RESULTS AND CONCLUSION:(1)A total of 477 differential genes were identified,265 differential genes associated with osteoarthritis were obtained by weighted gene co-expression network analysis,and 8 candidate core genes were identified.The least absolute shrinkage and selection operator regression analysis finally yielded a differential gene ASPM with core value that was externally validated.(2)It is concluded that abnormal gene ASPM expression screened by bioinformatics plays a key central role in osteoarthritis.

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.

Objective To explore the clinical features of fulminant type 1 diabetes mellitus (FT1DM). Methods The clinical data of 6 patients with FT1DM who were hospitalized in Jinshan Hospital of Fudan University from April 2020 to August 2024 were retrospectively analyzed. Their data were compared with that of 30 patients diagnosed with non-fulminant type 1 diabetes mellitus (NFT1DM) and diabetic ketosis or diabetic ketoacidosis (DKA) who were admitted to the hospital during the same period. The clinical characteristics of FT1DM were summarized. Results All 6 patients with FT1DM were male, with a disease course of 2.00 (1.75, 4.00) d. Three cases exhibited a history of prior infection, four tested positive for glutamic acid decarboxylase antibody (GADA), and five developed severe DKA. The glycated hemoglobin A_1C (HbA_1C) was (6.30±0.67) %, fasting C-peptide (FCP) was 0.07 (0.03, 0.15) ng/mL, 2-hour postprandial C-peptide (2h-CP) was 0.09 (0.03, 0.16) ng/mL. At discharge, all 6 patients received 4-injection insulin regimen, with a dose (0.69±0.15) U·kg⁻¹·d⁻¹. The body mass index (BMI), blood glucose/HbA_1C, blood potassium/HbA_1C, fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (2h-PG), high-sensitivity C-reactive protein (hs-CRP), alanine aminotransferase (ALT), serum creatinine, and blood potassium levels in the FT1DM group were higher than those in the NFT1DM group (P＜0.05), while HbA_1C and glycated albumin (GA) levels were lower than NFT1DM group (P＜0.05). Conclusions FT1DM usually presents with an acute onset of DKA, may be accompanied by a history of preceding infection, and GADA can be positive. Patients with FT1DM have elevated blood glucose/HbA_1C, blood potassium/HbA_1C, FPG, 2h-PG, hs-CRP, ALT, serum creatinine, blood potassium levels, and require insulin therapy, while the HbA_1C and GA levels are lower.

Diabetes is a common chronic non-infectious disease. Diabetic patients not only suffer from metabolic disorders, but are also prone to immune deficiencies and are at a higher risk of being infected with human papillomavirus (HPV). Many studies at home and abroad have shown that the HPV infection rate of patients with diabetes is higher than that of non-diabetic patients. Patients with diabetes can benefit from HPV vaccination, and the tolerance is good. HPV vaccination is recommended for diabetic patients. This article reviews the research on diabetes, HPV infection, and HPV vaccine, which will provide references for HPV vaccination in diabetic patients.
