Objective: To explore the types of medication adherence and their influencing factors among inpatients with chronic diseases based on latent profile analysis, so as to provide the basis for improving medication adherence among patients with chronic diseases. Methods: The inpatients with chronic diseases admitted to the Second Affiliated Hospital of Hainan Medical University were selected as the study subjects. Demographic information, chronic disease status, and health education were collected through questionnaire surveys. Medication adherence was assessed using the Medication Adherence Scale and categorized based on the scores of its eight items through latent profile analysis. Factors affecting medication adherence among inpatients with chronic diseases were analyzed using a multinomial logistic regression model. Results: Totally 290 valid questionnaires were recovered, with an effective recovery rate of 97.64%. There were 157 males (54.14%) and 133 females (45.86%), with a median age of 61 (interquartile range, 21) years. The median score of medication adherence was 4.75 (interquartile range, 4.50). Based on latent profile analysis, medication adherence was categorized into three types: subjective neglect with poor adherence (38.97%), subjective confidence with fluctuating adherence (28.28%), and self-reflective with good adherence (32.76%). Multinomial logistic regression analysis showed that compared to the subjective confidence with fluctuating adherence, family monthly income (5 000-10 000 yuan, OR=2.981, 95%CI: 1.055-8.429), comorbidity of chronic diseases (OR=3.478, 95%CI: 1.579-7.661), number of health education sessions received in the past year (≤1 session, OR=0.329, 95%CI: 0.120-0.907; 2 sessions, OR=0.363, 95%CI: 0.138-0.950), and health information literacy scores (<60 points, OR=2.596, 95%CI: 1.209-5.573) were statistically associated with subjective neglect with poor adherence (all P<0.05). Conclusion Subjective neglect with poor medication adherence among inpatients with chronic diseases is associated with family monthly income, comorbidity of chronic diseases, the number of health education sessions received, and health information literacy.

BACKGROUND: Asthma is a common chronic inflammatory airway disease and intermittent hypoxia is increasingly recognized as a factor that may impact disease progression. The present study investigated whether intermittent hypoxia (IH) could aggravate asthma by promoting hypoxia-inducible factor-1α (HIF-1α)/nucleotide-binding oligomerization domain (NOD)-like receptor pyrin domain-containing protein 3 (NLRP3)/interleukin (IL)-1β-dependent pyroptosis and the inflammatory response and further elucidated the underlying molecular mechanisms involved. METHODS: A total of 49 patients diagnosed with severe bronchial asthma and diagnosed by polysomnography were enrolled at Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, between January 2022 and December 2022, and their general data and induced sputum were collected. BEAS-2B cells were treated with IL-13 and subjected to IH. An ovalbumin (OVA)-treated mouse model was also used to assess the effects of chronic intermittent hypoxia (CIH) on asthma. Pyroptosis, the inflammatory response, and related signalling pathways were assessed in vivo and in vitro . RESULTS: In this study, as the apnoea and hypopnea index (AHI) increased, the proportion of patients with uncontrolled asthma increased. The proportions of neutrophils and the levels of IL-6, IL-8, HIF-1α and NLRP3 in induced sputum were related to the AHI. NLRP3-mediated pyroptosis, which could be mediated by the HIF-1α signalling pathway, was activated in IL-13 plus IH-treated BEAS-2B cells and in the lungs of OVA/CIH mice. HIF-1α downregulation significantly reduced lung pyroptosis and ameliorated neutrophil inflammation by modulating the NLRP3/IL-1β pathway both in vitro and in vivo . Similarly, pretreatment with LW6, an inhibitor of HIF-1α, effectively blocked the generation of inflammatory cytokines in neutrophils. In addition, administration of the NLRP3 activator nigericin obviously increased lung neutrophil inflammation. CONCLUSIONS Obstructive sleep apnoea-hypopnea syndrome (OSAHS) is a risk factor for asthma exacerbation. IH aggravates neutrophil inflammation in asthma via NLRP3/IL-1β-dependent pyroptosis mediated by the HIF-1α signalling pathway, which should be considered a potential therapeutic target for the treatment of asthma with OSAHS.

In current clinical practice, various dermal templates and skin substitutes are used to enhance wound healing. However, the role of wound commensal microbiome in regulating scaffold performance and the healing process remains unclear. In this study, we investigated the influence of both natural and synthetic scaffolds on the wound commensal microbiome and wound repair in three distinct models including diabetic wounds, burn injuries, and germ-free (GF) wounds. Remarkably, synthetic electrospun polycaprolactone (PCL) scaffolds were observed to positively promote microbiome diversity, leading to enhanced diabetic wound healing compared to the natural scaffolds Integra® (INT) and MatriDerm® (MAD). In contrast, both natural and synthetic scaffolds exhibited comparable effects on the diversity of the microbiome and the healing of burn injuries. In GF wounds with no detectable microorganisms, a reversed healing rate was noted showing natural scaffold (MAD) accelerated wound repair compared to the open or the synthetic scaffold (PCL) treatment. Furthermore, the response of the wound commensal microbiome to PCL scaffolds appears pivotal in promoting anti-inflammatory factors during diabetic wound healing. Our results emphasize that the wound commensal microbiome, mediated by different scaffolds plays an important role in the wound healing process.

OBJECTIVES: To investigate the therapeutic effect of electroacupuncture (EA) at Zusanli (ST36) acupoint on hyperlipidemia in mice and explore the underlying mechanisms. METHODS: Thirty C57BL/6J mice were equally randomized into normal diet group, high-fat diet (HFD) group, and EA group. The changes in blood lipids and serum malondialdehyde (MDA) content of the mice were evaluated, and histopathological changes and lipid accumulation in the liver were observed using Oil red O staining (ORO). The expressions of NLRP3, TLR4, and IL-1β proteins in the colon tissues were detected with Western blotting, and gut microbiota changes were analyzed using 16S rDNA sequencing. RESULTS: In mice with HFD feeding, 16 weeks of EA treatment significantly lowered body weight and serum TC, TG, LDL-C and MDA levels, obviously reduced lipid accumulation in the liver, and ameliorated HFD-induced elevations of protein expressions of NLRP3, TLR4, and IL-1β. 16S rRNA sequencing revealed that EA significantly altered gut microbiota composition, and increased the diversity and relative abundance of beneficial bacterial groups such as Muribaculaceae and Lachnospiraceae NK4A136_group. CONCLUSIONS Electroacupuncture at ST36 alleviates blood lipid disorders in hyperlipidemic mice possibly by improving intestinal microbiota structure, promoting degradation of high-caloric carbohydrates, cholesterol lipid metabolism and intestinal mucosa repair, and reducing toxin leakage, lipid peroxides, and liver fat deposition.

Peanut, a major economic and oil crop known for the high protein and oil content, is extensively cultivated in China. Peanut plants have the ability to form nodules with rhizobia, where the nitrogenase converts atmospheric nitrogen into ammonia nitrogen that can be utilized by the plants. Analysis of nodule fixation is of positive significance for avoiding overapplication of chemical fertilizer and developing sustainable agriculture. In this study, AhNIGT1.2, a member of the NIGT family predominantly expressed in peanut nodules, was identified by bioinformatics analysis. Subsequent spatiotemporal expression analysis revealed that AhNIGT1.2 was highly expressed in nodules and showed significant responses to high nitrogen, low nitrogen, high phosphorus, low phosphorus, and rhizobia treatments. Histochemical staining indicated that the gene was primarily expressed in developing nodules and at the connection region between mature nodules and peanut roots. The fusion protein AhNIGT1.2-GFP was located in the nucleus of tobacco epidermal cells. The AhNIGT1.2-OE significantly increased the number of peanut nodules, while AhNIGT1.2-RNAi reduced the number of nodules, which suggested a positive regulatory role of AhNIGT1.2 in peanut nodulation. The AhNIGT1.2-OE in roots down-regulated the expression levels of NRT1.2, NRT2.4, NLP1, and NLP7, which indicated that AhNIGT1.2 influenced peanut nodulation by modulating nitrate transport and the expression of NLP genes. The transcriptome analysis of AhNIGT1.2-OE and control roots revealed that overexpressing AhNIGT1.2 significantly enriched the differentially expressed genes associated with nitrate response, nodulation factor pathway, enzymes for triterpene biosynthesis, and carotenoid biosynthesis. These findings suggest that AhNIGT1.2 play a key role in peanut nodulation by regulating nitrate transport and response and other related pathways. This study gives insights into the molecular mechanisms of nitrogen and phosphorus in regulating legume nodulation and nitrogen fixation, and sheds light on the development of legume crops that can efficiently fix nitrogen in high nitrogen environments.

Objective To investigate the risk factors and intervention measures for surgical site infec-tion following posterolateral approach lumbar fusion surgery.Methods A total of 1 078 patients who under-went posterolateral approach lumbar fusion surgery in the department of spine surgery from January 1,2022 to December 31,2023 were included.Patient related information was collected through the real-time nosocomi-al infection monitoring system,while medical visit information was obtained via the outpatient electronic med-ical record system.Multivariate logistic regression analysis was performed to identify risk factors for surgical site infection.Results Among the 1 078 patients,34 cases(3.15%)developed surgical site infections,while 1 044 cases did not.Multivariate logistic regression analysis revealed that age,smoking,hypertension,diabetes,concurrent hospital stay,operative time,duration of postoperative antimicrobial use after initial surgery,and total antimicrobial use duration were significant risk factors for surgical site infection(P＜0.05).Among the 34 infected patients,the duration of antimicrobial use varied significantly across different infection sites(P＜0.05),with the longest duration observed in patients with deep space infections.Conclusion Targeted surveil-lance of surgical site infections should be reinforced based on these risk factors.Perioperative infection control measures must be strictly implemented to improve the scientific,precise,and standardized management of sur-gical-related nosocomial infections.

Objective To construct a logistic regression prediction model for stress ulcer(SU)after cerebral hemorrhage.Methods A total of 230 patients with cerebral hemorrhage admitted to our hospital from January 2020 to January 2023 were prospectively selected as the study subjects.They were randomly di-vided into a training group and a validation group using a random number table method,with 115 patients in each group.The incidence of postoperative SU was statistically compared between the two groups.The least absolute shrinkage and selection operator(Lasso)and logistic regression were used to analyze the influencing factors of SU after cerebral hemorrhage,and a logistic regression prediction model was established and valida-ted.Results The incidence of SU was 19.13%in the training group and 20.00%in the validation group.In-crement of age,blood loss≥30 mL,higher levels of neutrophil-to-lymphocyte ratio(NLR),heat shock protein 70(HSP70)and HSP90 were identified as independent risk factors for SU after cerebral hemorrhage(P<0.05),while lower levels of Glasgow Coma Scale(GCS)score and albumin(Alb)were protective factors(P<0.05).The prediction model was logit(P)=0.409×age+1.288×blood loss-1.335×GCS score-1.126×Alb+0.452×NLR+1.483×HSP70+1.593×HSP90-10.325.The areas under the receiver operat-ing characteristic(ROC)curve(AUC)for the training group and the validation group were 0.845(95%CI:0.765-0.906)and 0.855(95%CI:0.777-0.913),respectively.The sensitivities were 81.82%and 90.91%,and the specificities were 76.34%and 70.97%,respectively.Conclusion A logistic regression prediction model was successfully constructed,which has certain predictive value for SU after cerebral hemorrhage.

"Upper deficiency leading to vertigo" is one of the representative discussions on deficiency vertigo in Huang Di Nei Jing, which has laid the foundation for the rich development of the theory of "deficiency causing vertigo" in later generations. The brain lymphatic system can remove metabolic wastes and provide nutrients for the brain, which is involved in the development of many brain diseases. This study believes that the broad definition of "upper deficiency leading to vertigo", that is to say, vertigo is triggered by abnormalities in the local physiological functions of the brain orifices, can be used as a platform for the pathogenesis of vertigo. Based on the findings of modern medicine on the lymphoid system, the authors discussed the possible interactions between the lymphoid system, phlegm, blood stasis, deficiency, and other pathological factors of vertigo. β-amyloid, neurotransmitters, inflammatory mediators and other "toxic pathogenic factors" may also be an important cause of vertigo. This article attempted to explain the pathogenesis of "upper deficiency leading to vertigo" with the help of lymphoid system, in order to provide new thinking direction for the development of TCM clinical diagnosis and treatment of vertigo.

Objective: To investigate the expression of ribosomal protein L26 ( RPL26) in gastric cancer cells (GC) and its effect on cell apoptosis and proliferation . Methods: The expression of RPL26 in GES-1 and GC cell lines was detected by Western blot. GC cell line HGC-27 was used to construct RPL26 overexpression cell line , and GC cell lines HGC-27 and AGS cells were used to construct RPL26 knockdown cell line . The overexpression and knockdown efficiency of RPL26 were detected by Western blot. Cell counting kit-8 (CCK-8) , colony formation assay and Transwell assay were used to detect the effects of the overexpression and knockdown of RPL26 on the pro- liferation and migration of GC cells . Western blot was used to detect the expression of Phosphatidylinositol-3-kinase (PI3K) / protein kinase B (AKT) signaling pathway related factors PI3K , AKT , phosphorylated phosphatidylinosi- tol-3-kinase (p-PI3K) , phosphorylated protein kinase B ( p-AKT) and downstream factors B-Cell lymphoma-2 (Bcl-2) , Bcl-2 associated X protein (Bax) and Cyclin A , G1 /S-specific Cyclin D1(Cyclin D1) , Cyclin-depend- ent kinases (CDK)4 and CDK2 in overexpression and knockdown of RPL26 stably transfected cell lines . Results: Compared with GES-1 , RPL26 was highly expressed in HGC-27 cells ( tHGC-27 = 4. 97 ; P < 0. 01) and elevated in AGS , but the difference was not statistically significant. In HGC-27 and AGS cells , CCK-8 and colony formation assays showed that the proliferation ability of cells decreased after the knockdown of RPL26. Transwell assay showed that the migration ability of cells decreased after the knockdown of RPL26. Western blot showed that Bcl-2 expression was decreased in HGC-27 , AGS cells after the knockdown of RPL26 ( tHGC-27 = 11 . 50 , tAGS = 4. 77 ; P < 0. 001 , P < 0. 01) , and Bax expression increased ( tHGC-27 = 9. 63 , tAGS = 4. 05 ; P < 0. 001 , P < 0. 05) . In HGC-27 cells , the ratios of p-PI3K/PI3K and p-AKT/AKT significantly decreased after the knockdown of RPL26 ( tp-PI3K/PI3K = 3 . 86 , tp-AKT/AKT = 8. 29 ; P < 0. 05 , P < 0. 01) . Cyclin A , Cyclin D1 , CDK4 , CDK2 protein expressions de- creased ( t = 9. 61 , 5 . 10 , 11 . 64 , 7. 81 ; P < 0. 01 or P < 0. 001) , while the overexpression of RPL26 in HGC-27 cells showed the opposite trend . Conclusion The knockdown of RPL26 may arrest the cell cycle in G1 /S phase by inhibiting the PI3K/AKT signaling pathway , thereby inhibiting cell proliferation and promoting apoptosis .

Objective To investigate the expression of α7 nicotinic acetylcholine receptor (α7nAChR) in thymic T follicular helper cells (TFH) and its significance in patients with myasthenia gravis (MG). Methods Fifteen MG patients who underwent surgical treatment at the Myasthenia Gravis Comprehensive Diagnosis and Treatment Center of Henan Provincial People’s Hospital from June 2022 to June 2023 were selected as a MG group, including 7 males and 8 females, aged 12-30 years. Twelve patients who underwent partial thymectomy to optimize surgical field exposure during cardiac surgery at Fuwai Central China Cardiovascular Hospital from June 2022 to June 2023 were selected as a control group, including 5 males and 7 females aged 20-35 years. Thymus single cell suspension was obtained by grinding the thymus tissue, and flow cytometry was used to detect the expression of α7nAChR in TFH cells. The thymus cell suspension was purified using density gradient centrifugation, followed by immunomagnetic bead separation to obtain CD4+T cells. CXCR5 antibody and coupled magnetic beads were added to isolate TFH cells. Real-time fluorescent polymerase chain reaction and Western blotting were performed to further investigate the expression of α7nAChR in TFH cells. Results Compared with the control group, the proportion of thymic TFH cells in the MG group was significantly increased (P<0.05), along with significantly decreased mRNA and protein expression levels of α7nAChR within these cells (P<0.01). Conclusion The findings suggest that there is a reduced expression of α7nAChR within thymic TFH cells in MG patients, leading to weakened immunosuppressive function which may indirectly contribute to disease onset and progression.
