Stroke has become the first cause of death and disability in Chinese adults, which is characterized by high incidence rate, high recurrence rate, high disability rate, high mortality and high economic burden. Osteoporosis or bone loss are common after stroke, and decreased bone density may also be a risk factor for ischemic stroke. Although the correlation between the two has been confirmed, the underlying mechanism is not yet fully understood. This article reviews the association between the decreased bone density and stroke, as well as the screening and treatment of osteoporosis in stroke survivors.

Objective:To investigate the clinicopathological characteristics of oxyntic gland adenoma(OGA)and gastric adenocarcinoma of the fundic gland type(GA-FG).Methods:Six cases of fundic gland-type tumors(three OGA and three GA-FG)diagnosed at the Fujian Cancer Hospital between August 2020 and February 2023 were retrospectively analyzed.The clinical data,endoscopic features,pathological charac-teristics,immunohistochemical results,treatment,and prognosis were analyzed.Results:Six patients with an average age of 57 years,in-cluding one male and five females,were mainly affected in the gastric fundus and body,with the superficial elevated type being the most common.The pathological features of gastric gland-type tumors are mostly located in the deep layer of the gastric mucosa,showing a dis-ordered glandular structure mainly composed of chief cell-type cells.There were three cases of OGA and three cases of GA-FG.Immunohis-tochemical results showed that pepsinogen 1 was positive in five cases,mucin 6(MUC6)in five cases,synaptophysin(Syn)in six cases,chro-mogranin(CgA)was negative in all cases,and Ki-67 was less than 10%.Conclusions:The incidences of OGA and GA-FG are low,and there is no obvious endoscopic specificity.Endoscopy physicians have an insufficient understanding,which can easily lead to misdiagnoses and missed diagnoses.Immunohistochemistry is helpful for the differential diagnosis,and endoscopic mucosal resection or stripping is the pre-ferred treatment option.

Objectives: . The necessity to develop a method for prognostication and to identify novel biomarkers for personalized medicine in patients with head and neck squamous cell carcinoma (HNSCC) cannot be overstated. Recently, pathomics, which relies on quantitative analysis of medical imaging, has come to the forefront. CXCL8, an essential inflammatory cytokine, has been shown to correlate with overall survival (OS). This study examined the relationship between CXCL8 mRNA expression and pathomics features and aimed to explore the biological underpinnings of CXCL8. Methods: . Clinical information and transcripts per million mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA)-HNSCC dataset. We identified correlations between CXCL8 mRNA expression and patient survival rates using a Kaplan-Meier survival curve. A retrospective analysis of 313 samples diagnosed with HNSCC in the TCGA database was conducted. Pathomics features were extracted from hematoxylin and eosin–stained images, and then the minimum redundancy maximum relevance, with recursive feature elimination (mRMR-RFE) method was applied, followed by screening with the logistic regression algorithm. Results: . Kaplan-Meier curves indicated that high expression of CXCL8 was significantly associated with decreased OS. The logistic regression pathomics model incorporated 16 radiomics features identified by the mRMR-RFE method in the training set and demonstrated strong performance in the testing set. Calibration plots showed that the probability of high gene expression predicted by the pathomics model was in good agreement with actual observations, suggesting the model’s high clinical applicability. Conclusion . The pathomics model of CXCL8 mRNA expression serves as an effective tool for predicting prognosis in patients with HNSCC and can aid in clinical decision-making. Elevated levels of CXCL8 expression may lead to reduced DNA damage and are associated with a pro-inflammatory tumor microenvironment, offering a potential therapeutic target.

Objective:To explore the contents and methods of clinical comprehensive evaluation of microecologics, with the example of Bifidobacterium quadruple viable tablet, in order to provide evidence for clinical rational use of microecologics, and microecologics research, development and related decision-making, and to promote rational use of medications. Methods:Based on the research data collected from systematic literature search, health technology assessment methods such as evidence-based medicine and pharmacoeconomics evaluation were used to estimate the safety, efficacy, economics, suitability, accessibility and innovation of Bifidobacterium quadruple viable tablet. Results:In terms of efficacy, Bifidobacterium quadruple viable tablet showed significant therapeutic effects in the treatment of pediatric diarrhea, antibiotic-related diarrhea, diarrhea-predominant irritable bowel syndrome, and secondary diarrhea caused by diseases such as ulcerative colitis, as well as constipation and functional dyspepsia. It can also be used in the treatment of various diseases such as Helicobacter pylori related gastritis, liver cirrhosis, non-alcoholic fatty liver disease. In terms of safety, the incidence of adverse effects of this medication was low, and most were mild to moderate and transient symptoms. In terms of economics, compared with mesalazine alone in the treatment of ulcerative colitis, the incremental cost-effectiveness ratio of combination of Bifidobacterium quadruple viable tablet and mesalazine was 1 743.2. Besides, the daily treatment cost of Bifidobacterium quadruple viable tablet was lower than that of combination of Bifidobacterium triple viable and Bacillus licheniformis (1.87 to 2.80 yuan vs. 2.08 to 5.78 yuan). In terms of innovation, this medication had multiple patents and had been identified as a high-tech product in Zhejiang Province. In terms of suitability, the overall suitability of use and technical characteristics of medication were good. It could be further improved in the aspects of dosage form and system. In terms of accessibility, the price of the medication was stable, affordable and accessible to the general public. Conclusions:Based on the existing evidence, Bifidobacterium quadruple viable tablet presented effective with supported evidences, good safety, accessibility and innovation. The suitability can be further optimized. However, more in-depth and targeted research is needed in terms of economics and innovation in different clinical applications, and there is space for optimization in medication suitability.

Objective:To systematically analyze and integrate the real experience of puerpera in free delivery positions.Methods:Qualitative or mixed method studies on attitudes and emotional experiences of puerpera towards free delivery positions were retrieved through computer on PubMed, ScienceDirect, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, and WanFang Data. The search period was from database establishment to November 30, 2022. The quality of literature was evaluated using the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center in Australia. The aggregation integration method was used to integrate the results.Results:A total of 5 articles were included and 28 results were extracted. The results were summarized into 10 categories, and 3 integrated results were formed, including factors that affected the choice of delivery position, the complex delivery experience of the puerpera, and the hope for much support.Conclusions:Hospitals, communities, and families should fully understand women's emotional experiences and needs for free delivery positions, provide sufficient support and guidance, and provide a reference basis for developing a reasonable delivery position plan and promoting a positive delivery experience.

Objective:To improve the understanding of indolent mantle cell lymphoma (MCL).Methods:The data of a patient with indolent leukemic MCL in the Second Affiliated Hospital of Nanjing Medical University in May 2013 were collected. The cell morphology was analyzed by using cell smear, the flow cytometry was used to make immunophenotype analysis, the karyotype analysis was performed by usig cytogenetic technique, and polymerase chain reaction (PCR) was used to make the immunoglobulin gene analysis. At the same time, lymph node pathology and immunohistochemistry were also analyzed. The related articles published were reviewed to sum up the characteristics and the treatment of indolent MCL.Results:The male patient aged 60 years was obviously asymptomatic accompanied with slow disease progression, leukemic manifestation and without lymphadenopathy. He received pathological biopsy because of located lymphadenopathy in 2008. Small cell morphology, Kappa light chain immunophenotype, t(11;14) translocation showed after the cytogenetic examination, clonal immune globulin gene rearrangement and low Ki-67 positive index were identified. In situ MCL was diagnosed by retrospective pathology.Conclusions:Indolent MCL is extremely rare. It is typically asymptomatic with none or minimal nodal involvement, indolent disease course, leukemic phase with mild lymphocytosis, Kappa light chain expression, simple karyotype, classical or small cell morphology of tumor cells and the positive index of Ki-67 <10%. In situ MCL can be seen in pathology examination. IgVH gene mutation positive and SOX11 negative expression are notable in indolent MCL. International prognostic index of MCL is probably not appropriate in the prognostic analysis of leukemic indolent MCL. It is emphasized that initial observation and having therapies only after the disease progression can be suited for indolent MCL.

Objective:To explore the effect of recombinant human syntaxin-4(STX4) on lipopolysaccharide(LPS)-induced injury in islet β-cells(INS-1).Methods:Pancreatic islet β-cells(INS-1) were divided into Control (blank control), LPS (LPS treatment), LPS+ NC (transfection of negative control vector, LPS treatment), and LPS+ STX4 (transfection of pcDNA-STX4, LPS treatment) groups. RT-qPCR and Western blot were used to detect STX4 mRNA and protein expression, flow cytometry to detect apoptosis, DCFHDA method to detect reactive oxygen species(ROS) level, xanthine oxidation method to detect superoxide orgotein dismutase(SOD) level, colorimetric method to detect glutathione peroxidase(GSH-Px) level, ammonium molybdate colorimetric method to detect catalase(CAT) level, thiobarbituric acid method to detect malonaldehyde(MDA) level, ELISA method to detect the level of interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), and insulin secretion levels under glucose conditions secreted by cells, Western blot method to detect Cleared Caspase-3, Bcl-2 Associated X Protein(Bax), p65 protein expression. After treatment with NF-κB signaling pathway activator, STX4 up-regulated islet β-cell INS-1 was given LPS stimulation, and the same method was used to measure apoptosis, ROS, SOD, GSH-Px, CAT, MDA levels and secreted IL-1β, TNF-α, insulin levels and Cleaved Caspase-3, Bax, p65 protein levels.Results:Compared with the Control group, the expression of STX4 mRNA and protein in islet β cells of the LPS group decreased, the apoptosis rate, ROS level, and MDA levels increased, and the levels of SOD, GSH-Px, and CAT decreased, the levels of IL-1β, TNF-α increased, the level of insulin secreted by the cells decreased, and the expression levels of Cleaved Caspase-3, Bax, and p65 also increased. NF-κB pathway activator treatment reversed the effect of up-regulated STX4 on islet β-cell apoptosis, ROS, SOD, GSH-Px, CAT, MDA levels and secreted IL-1β, TNF-α levels, and Cleaved Caspase-3 , Bax and p65 protein levels.Conclusion:Up-regulation of STX4 alleviated LPS-induced islet β cell oxidative damage, apoptosis and inflammatory factor release. The underlying mechanism might be related to the inhibition of activated NF-κB signaling pathway.

Objective:To investigate the clinical features and prognosis of extranodal nasal-type NK/T-cell lymphoma of the extra-upper aerodigestive tract (extra-UADT NKTCL).Methods:The clinical data of 159 patients with extra-UADT NKTCL from the China Lymphoma Collaborative Group (CLCG) database between November 2001 and December 2015 were retrospectively analyzed. Kaplan-Meier survival analysis and Log-rank test were used to evaluate the prognosis. The Cox regression model is used for multi-factor analysis.Results:Extra-UADT NKTCL commonly occurs in skin and soft tissues (106/159, 66.7%) and gastrointestinal tract (31/159, 19.5%). The incidences of elevated lactate dehydrogenase (LDH) and Ann Arbor Ⅲ~Ⅳ stage were 47.8% (76/159) and 64.2% (102/159), respectively. The 3-year overall survival (OS) and progression-free survival (PFS) rates were 43.6% and 27.9%, respectively. The corresponding OS rates of primary skin/soft tissue site and gastrointestinal tract site were 41.0% and 59.4% ( P=0.281), while the PFS rates were 24.8% and 48.3%, respectively ( P=0.109). Combined modality treatment improved the 3-year OS of all the patients (58.4% vs 33.9%, P=0.001) and 3-year PFS (40.7% vs 20.7%, P=0.008) when compared with chemotherapy alone. LDH elevation, Ann Arbor synthesising and ≥2 junction external bits were intrusive as independent risk factors for total survival ( P<0.05), LDH elevation and ≥2 junction outer bits were intrusive as independent risk factors for progressionless survival( P<0.05). The distant extranodal dissemination was the primary failure patterns. Conclusions:Extra-UADT NKTCL appears to have distinct clinical characteristics and poor outcome. Compared with chemotherapy alone, combined modality treatment may improve the prognosis of patients with extra-UADT NKTCL.

Objective:To evaluate the prognosis and determine the failure patterns after radiotherapy for low-risk early-stage patients with extranodal NK/T-cell lymphoma, nasal-type (ENKTCL).Methods:A total of 557 patients from 2000—2015 with low-risk early-stage ENKTCL who received radiotherapy (RT) with or without chemotherapy (CT) from China Lymphoma Collaborative Group were retrospectively reviewed. Among them, 427 patients received combined modality therapy, whereas 130 patients received RT alone. Survivals were calculated by Kaplan-Meier method and compared with Log-rank test. Overall survival (OS) was compared with age and sex-matched general Chinese population using expected survival and standardized mortality ratio (SMR). Cox stepwise regression model was used for multivariate analysis.Results:The 5-year OS and progression-free survival (PFS) were 87.2% and 77.2%. The SMR was 3.59 ( P<0.001) at 1 year after treatment, whereas it was 1.50 at 4 years after treatment, without significant difference between ENKTCL group and country-matched general population ( P=0.146). Compared with RT alone, CMT did not result in significantly superior 5-year OS (87.0% vs 87.4%, P=0.961) or PFS (76.1% vs 80.7%, P=0.129). Local failure (11.5%, 64/557) and distant failure (10.8%, 60/557) were the main failure modes, while regional failure was rare (2.9%, 16/557). The 5-year locoregional control rate (LRC) was 87.2% for the whole group, with 89.5% for ≥50 Gy versus 73.7% for <50 Gy ( P<0.001). Radiotherapy dose was an independent factor affecting LRC( P<0.05). Conclusions:Radiotherapy achieves a favorable prognosis in patients with low-risk early-stage ENKTCL. The incidence of either locoregional or distant failure is low. Radiation dose still is an important prognostic factor for LRC.
