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.

ObjectiveTo investigate the mechanism by which Liuwei Dihuang Erzhiwan combination inhibit the lung metastasis of spontaneous breast cancer in mice by regulating the recruitment of myeloid-derived suppressor cells (MDSCs). MethodThree hundred and eighty SPF-grade 10-month-old female breeders of Kunming mouse were palpated at the mammary gland site once every 3 days. Mice that have not had a lump touched after being raised for 6 months are used as control group. After tumor development, the mice were randomized into model, positive control (paclitaxel, intraperitoneal injection at 0.01 g·kg-1 every other day for 22 d), Liuwei Dihuangwan (0.65 g·kg-1·d-1 by gavage), Erzhiwan (5.41 g·kg-1·d-1 by gavage), and Liuwei Dihuang Erzhiwan combination (6.05 g·kg-1·d-1 by gavage) groups. The mice were euthanised when the tumor reached a diameter of about 15 mm, and the tumor and lung tissues were collected. The survival time, tumor mass, and lung metastasis rate of tumor-bearing mice were recorded. Hematoxylin-eosin (HE) staining was used to observe the histopathological and morphological changes of mouse tumor and lung tissues. Immunofluorescence (IF) was used to detect the distribution of MDSCs in tissues of mice in each group by double-staining of MDSCs cells with lymphocyte antigen 6 complex site G6D (Ly6G) and CD11 antigen-like family member B (CD11b). Western blot was employed to determine the protein levels of matrix metalloproteinase-9 (MMP-9), transforming growth factor-β (TGF-β), zinc finger transcription factor 1 (Snail1), and E-cadherin in the tumor tissue and CC motif chemokine 9 (CCL9) and CC motif chemokine receptor 1 (CCR1) in the lung tissue. ResultDuring the modelling period, the paclitaxel group and Chinese medicine intervention groups had longer median number of days of survival and lower tumor weight, lung metastasis rate, and lung nodule than the model group (P<0.05, P<0.01). HE staining showed an increase in tumor cell necrosis in the paclitaxel group and the Liuwei Dihuang Erzhiwan combination group. The paclitaxel group and Chinese medicine intervention groups had lower fluorescence intensity of MDSCs in the tumor tissue than the model group (P<0.05, P<0.01). Compared with the normal control group, the model group showed increased fluorescence intensity of MDSCs in the metastatic lung tissue (P<0.01), which, however, was decreased in the paclitaxel group and Chinese medicine intervention groups (P<0.01). The model group showed higher protein levels of MMP-9, TGF-β, and Snail1 and lower protein level of E-cadherin in the tumor tissue than in the normal control group (P<0.01). Compared with model group, paclitaxel and Chinese medicine interventions downregulated the protein levels of MMP-9, TGF-β, and Snail1 (P<0.05, P<0.01) and upregulated the protein level of E-cadherin in the tumor tissue (P<0.01). Moreover, the Liuwei Dihuang Erzhiwan combination group had lower protein levels of TGF-β and Snail1 than the Liuwei Dihuangwan group and Erzhiwan group (P<0.05). In the metastatic lung tissue, the expression of CCL9 and CCR1 was higher in the model group than in the normal control group, paclitaxel group, and Chinese medicine intervention groups (P<0.05, P<0.01). ConclusionLiuwei Dihuang Erzhiwan combination inhibit tumor growth, prolong survival time, and reduce the occurrence of lung metastasis in the mouse model of spontaneous breast cancer by reducing the recruitment of MDSCs in the tumor and lung tissues and modulating the phenotypes of epithelial-mesenchymal transition (EMT)-related molecules and the expression of CCL9/CCR1.

ObjectiveTo establish a mouse model of basilar artery dolichoectasia (BAD) and explore the mechanism of modified Tongqiao Huoxuetang (JTQHX) in regulating BAD via phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway. MethodSixty C57/BL6 female mice were randomized into sham operation (injected with 10 U·mL-1 inactivate elastase), model, atorvastatin calcium tablets (2.6 mg·kg·d-1), and low- and high-dose (crude drug 3.4, 17 g·kg-1·d-1, respectively) JTQHX groups. The mouse model of BAD was established by injection with 10 U·mL-1 elastase. After 14 days of modeling, the sham operation group and model group were administrated with equal volumes of pure water by gavage, and other groups with corresponding drugs for 2 months. The levels of interleukin-6 (IL-6) and calpain (LpA) in the serum were measured by enzyme-linked immunosorbent assay (ELISA). Verhoeff 's Van Gieson (EVG) staining was employed to observe the pathological changes of blood vessels. Terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) was employed to examine the apoptosis rate of vascular smooth muscle cells (VSMCs). Image Pro Plus was used to observe and calculate the curvature index, elongation length, percentage increase in vessel diameter, and curvature angle of the basilar artery vessels in mice. Western blot was employed to determine the expression levels of PI3K and Akt in the vascular tissue. ResultCompared with the sham operation group, the model group showed lowered IL-6 level (P<0.01), no significant change in LpA level, increased apoptosis of VSMCs (P<0.01), and increased curvature index, elongation length, percentage increase in vessel diameter, and curvature angle (P<0.01). Furthermore, the modeling up-regulated the protein levels of PI3K and Akt in blood vessels (P<0.01) and aggravated the destruction of the inner elastic layer, atrophy of the muscular layer, and hyaline changes in the connective tissue of the medial membrane of the basilar artery wall. Compared with the model group, 2 months of treatment with JTQHX elevated the IL-6 level (P<0.01), reduced the apoptosis of VSMCs (P<0.01), decreased the curvature index, elongation length, percentage increase in vessel diameter, and curvature angle (P<0.05, P<0.01), and down-regulated the protein levels of PI3K and Akt in blood vessels (P<0.01). In addition, the treatment alleviated the destruction of the inner elastic layer, atrophy of the muscular layer, and hyaline changes in the connective tissue of the medial membrane of the basilar artery wall. ConclusionJTQHX inhibits the elongation, expansion, and curvature of basilar artery vessels and alleviates the pathological changes by reducing the apoptosis of VSMCs and down-regulating the expression of PI3K/Akt pathway.
