ObjectiveTo investigate the effects of Huayu Jiedu prescription on brain microvascular endothelial cells (BMECs) after oxygen-glucose deprivation (OGD) injury and to explore its intervention mechanisms. MethodsThe cell counting kit-8 (CCK-8) assay was used to determine the optimal OGD duration and the effective concentration of Huayu Jiedu prescription-containing serum. Cells were randomly divided into the blank serum medium group (KBXQ), model group (OGD), HYXQ group (OGD + Huayu Jiedu prescription-containing serum), and 3-methyladenine (3-MA) group (OGD + 3-MA). Cell morphology was observed under an inverted microscope. The numbers of autophagosomes and autolysosomes in cells were observed by transmission electron microscopy. Cell viability was determined using the CCK-8 assay. Cell apoptosis rate was detected using the TdT-mediated dUTP nick-end labeling (TUNEL) assay. The expression levels of microtubule-associated protein 1 light chain 3 (LC3) and Occludin were detected by immunofluorescence. The permeability of the cell monolayer was also measured. Cells were further randomly divided into the KBXQ group, model group (OGD), HYXQ group, phosphatidylinositol-3 kinase (PI3K) inhibitor (LY294002) group (OGD + LY294002), and HYXQ + LY294002 group (OGD + Huayu Jiedu prescription-containing serum + LY294002). Western blot analysis was used to detect the expression levels of the autophagy-related key molecule yeast Atg6 homolog 1 (Beclin1), LC3Ⅱ/LC3Ⅰ, selective autophagy adaptor protein (p62), Occludin, phosphorylated (p)-PI3K, PI3K, phosphorylated protein kinase B (p-Akt), Akt, phosphorylated mammalian target of rapamycin (p-mTOR), and mTOR. ResultsOGD for 6 h was selected as the optimal modeling condition, and 5% was determined as the optimal volume fraction of Huayu Jiedu prescription-containing serum. Compared with the KBXQ group, the model group showed obvious cell damage under the inverted microscope, and transmission electron microscopy revealed markedly increased numbers of autophagosomes and autolysosomes. Cell viability was significantly decreased (P<0.01), apoptosis rate was significantly increased (P<0.01), LC3 fluorescence intensity was significantly increased (P<0.01), Occludin fluorescence intensity was significantly decreased (P<0.01), and monolayer permeability was significantly increased (P<0.01). Compared with the model group, cell damage in the HYXQ group and the 3-MA group was significantly improved, the numbers of autophagosomes and autolysosomes were markedly reduced, cell viability was significantly increased (P<0.01), apoptosis rate was significantly decreased (P<0.01), LC3 fluorescence intensity was significantly decreased (P<0.01), Occludin fluorescence intensity was significantly increased (P<0.01), and monolayer permeability was reduced (P<0.05). Western blot results showed that, compared with the KBXQ group, the model group exhibited significantly increased expression of Beclin1 and LC3Ⅱ/LC3Ⅰ (P<0.01), while the expression levels of p62, Occludin, p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR were significantly decreased (P<0.01). Compared with the model group, the HYXQ group showed significantly decreased expression of Beclin1 and LC3Ⅱ/LC3Ⅰ (P<0.01) and significantly increased expression of p62, Occludin, p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR (P<0.01). In the LY294002 group, Beclin1 and LC3Ⅱ/LC3Ⅰ expression were significantly increased (P<0.05, P<0.01), whereas the expression levels of p62, Occludin, p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR were significantly decreased (P<0.01). Compared with the LY294002 group, the HYXQ + LY294002 group showed significantly decreased expression of Beclin1 and LC3Ⅱ/LC3Ⅰ (P<0.01) and significantly increased expression of p62, Occludin, p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR (P<0.01). ConclusionHuayu Jiedu prescription has a protective effect on BMECs after OGD injury, which may be achieved by activating the PI3K/Akt/mTOR autophagy-related signaling pathway and inhibiting excessive autophagy, thereby protecting Occludin protein expression and endothelial barrier function.

Objective To investigate prevalence and immunological properties of Helicobacter pylori (Hp) infection among chronic gastritis population in Wuhan. Methods A total of 1 866 patients with chronic gastritis in Wuhan were selected from May 2021 to December 2023, and Hp antibody and typing in serum were detected by immunoblotting to analyse the infection rate and typing of patients of different genders and age groups, as well as the correlation between Hp infection and the severity of chronic gastritis. Western blotting technique was utilized to detect the Hp antibodies and typing. The infection rates and subtypes were recorded in patients of different genders and ages. Then the correlation between Hp infection and the severity of chronic gastritis were discussed. Results The overall detection rate of Hp infection was 65.38% (1 220/1 866) in 1866 patients, and the prevalence rate of type I infection was higher than that of type II infection [61.31% (748/1 220) vs 38.69% (472/1 220), P<0.05]. No statistical difference was reported in overall infection rate in terms of gender (P>0.05). In terms of gender, the rate of type I infection was higher than that of type II infection [70.08% (431/615) vs 29.92% (184/615), P<0.05], whereas the prevalence of the two types of infections demonstrated no statistical difference in female patients (P>0.05). In terms of age, the prevalence of Hp infection in patients increased with age (2=64.687, P=0.000). The infection rate of type I was higher than type II in the age groups of below 18, 31-40, 41-50 and 51-60 years old (P<0.05), and infection rates of type I and type II yielded no statistical difference in the age groups of 18-30 and ≥60 years old (P>0.05). With the aggravation of chronic gastritis, the infection rate and percentage of type I infections increased, and the percentage of type I infections was higher than that of type II infections (P<0.05). Conclusion Patients with chronic gastritis in Wuhan suffer a high prevalence rate of Hp infection, and the rate of Hp infection increases with the age of the patients, is positively correlated with the severity of the disease, and presents certain typological features.

OBJECTIVE:
To assess the effectiveness of bone acupuncture in improving pain and function in degenerative lumbar spinal stenosis (DLSS) and compare it with Jiaji acupuncture.
METHODS:
From January to December 2023, 80 DLSS patients were treated with acupuncture and divided into bone acupuncture and Jiaji acupuncture groups. Among them, 40 patients in the bone acupuncture group included 15 males and 25 females, with a mean age of (60.60±6.98) years old;anthor 40 patients in the Jiaji acupuncture group included 16 males and 24 females, with a mean age of (61.48±9.55) years old. The Roland Morris disability questionnaire(RMDQ), walking distance, visual analogue scale(VAS), and the MOS item short from health survey(SF-36) of two groups at baseline, 2 weeks, 4 weeks, and 12 weeks post-treatment were compared.
RESULTS:
Eighty patients were followed up for 3 to 5 months with an average of (3.62±0.59) months. There was no significant differences in general data and the scores before treatment between two groups(P>0.05). The RMDQ scores in both groups decreased significantly at 2, 4 and 12 weeks after treatment compared with before treatment(P<0.05), at each time point after treatment, the decrease was more significant in the bone acupuncture group than in the Jiaji acupuncture group(P<0.05). The VAS of waist and leg in both groups was significantly lower at 2, 4 and 12 weeks after treatment that before treatment(P<0.05). At all time points after treatment, the waist VAS in the bone acupuncture group was reduced more significant than in the Jiaji acupuncture group(P<0.05);there was no significant difference in leg VAS at 2 and 12 weeks after treatment between two groups(P>0.05), the improvement was more significant in the bone acupuncture group in the 4 weeks after treatment than in the Jiaji acupuncture group. The SF-36 scores in both groups were significantly higher at 2, 4, and 12 weeks after treatment than before treatment(P<0.05);the SF-36 score raised more significant in the bone acupuncture group than in the Jiaji acupunture group(P<0.05). No significant difference in the walking distance between two groups at 2 weeks after treatment(P>0.05);the walking distance in the bone acupuncture group was significantly higher than that in the Jiaji acupuncture group at 4 and 12 weeks after treatment(P<0.05).
CONCLUSION
Bone-penetrating acupuncture moderately improves functional impairment, pain, and quality of life in patients with DLSS, showing better efficacy than Jiaji acupuncture.

The gradient coils of MRI equipment can induce vibrations in implantable medical devices, causing periodic vibrations of implantable medical devices with respect to the surrounding tissue. This not only results in instrument failure but also causes discomfort to the patient. Therefore, studying the vibration characteristics of implantable devices under different scanning sequences and the orientation of the device relative to the magnetic field is crucial for comprehending vibration performance. This study observed the vibration spectra of a full cranial bone-implanted neurostimulator by using laser vibrometry under typical rapid imaging sequences and explored the impact of different magnetic field orientations on vibration. The results demonstrated that the rapid echo sequences induced diverse and rich vibration components, whereas the planar echo sequences caused relatively simple vibrations. Additionally, the strongest vibrations normally occurred in the maximum conductive surface parallel to the phase-coded direction. It revealed the factors influencing the vibrations of skull fixation active implantable devices and provided guidance for enhancing device safety and protecting patient well-being during MR examinations.

OBJECTIVE:
To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM).
METHODS:
This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis.
RESULTS:
Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings.
CONCLUSIONS
RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Acupuncture is an ancient treatment method used in traditional Chinese medicine and has been popularized worldwide. Over the past decade, there has been an increase in the amount of acupuncture research, mostly comprised of randomized controlled trials (RCTs) that aimed to answer the question on the efficacy of acupuncture. However, poor methodology and low replicability in these acupuncture RCTs have resulted in uncertainty about the efficacy of acupuncture. In this review, current advancements and challenges in acupuncture RCTs, regarding the methodological aspects of randomization, blinding, sham acupuncture and quality of reporting, were discussed. While there have been advancements in various aspects, current acupuncture RCTs still face pressing issues such as inadequate randomization and blinding, unviable sham acupuncture controls, and poor reporting quality. Given these limitations, this review seeks to identify the methodological problems that are responsible for these problems and to suggest solutions that could help to overcome them so as to improve the quality of future studies evaluating the efficacy of acupuncture.

ObjectiveTo investigate the effects and mechanism of Zuogui Jiangtang Tongmai prescription (ZJTP) on human umbilical vein endothelial cells (HUVECs) damaged by high glucose combined with lipopolysaccharide (LPS). MethodThe survival rate of cells was determined by cell counting kit-8 (CCK-8), and the level of tumor necrosis factor-α (TNF-α) was determined by enzyme-linked immunosorbent assay (ELISA) to determine the optimal injury concentration and action time of LPS, as well as the optimal action concentration of ZJTP drug-containing serum. HUVECs were divided into a blank control group, a model group, a ZJTP drug-containing serum group, and an SCFA mixed liquid group. ELISA was used to detect the level of endothelin-1 (ET-1), nitric oxide (NO), interleukin-1β (IL-1β), interleukin-6 (IL-6), and TNF-α. Western blot was performed to detect the protein expression of G protein-coupled receptor43 (GPR43), β-suppressor protein-2 (β-arrestin-2), nuclear factor-κB suppressor α (IκBα), and nuclear factor κB p65 (NF-κB p65). The nucleation of NF-κB p65 was observed by immunofluorescence staining (IF). The role of GPR43 in the regulation of inflammatory injury was observed by means of small interfering ribonucleic acid (siRNA). The cells after intervention were divided into an empty carrier group, a ZJTP drug-containing serum group, a Si-GPR43 group, and a Si-GPR43 + ZJTP drug-containing serum group. The content of IL-1β, IL-6, and TNF-α was detected by ELISA. The protein expression of pathways was detected by Western blot. IF was used to observe the nucleation of NF-κB p65. ResultThe optimal molding condition was 1 mg·L-1 LPS for 24 h. The optimal drug intervention condition was 5% ZJTP drug-containing serum for 24 h. Compared with the blank control group, the content of ET-1 in the model group was significantly increased, and the content of NO was significantly decreased (P<0.01). The levels of inflammatory factors were significantly increased (P<0.01). The expressions of GPR43 and IκBα were significantly decreased, while the protein expressions of β-arrestin-2 and NF-κB p65 were significantly increased (P<0.01). NF-κB p65 protein was transferred from the extranuclear to the intranuclear (P<0.01). Compared with the model group, the content of ET-1 in the ZJTP drug-containing serum group was decreased, and the content of NO was increased (P<0.05). The levels of inflammatory factors decreased (P<0.05). The protein expressions of GPR43 and IκBα were increased, while the expressions of β-arrestin-2 and NF-κB p65 were decreased (P<0.05). The amount of NF-κB p65 transferred from the intranuclear to the extranuclear decreased (P<0.01). The mechanism study showed that compared with the Si-GPR43 group, the content of IL-1β, IL-6, and TNF-α were significantly decreased after treatment with ZJTP drug-containing serum (P<0.01). The protein expressions of GPR43 and IκBα were significantly increased (P<0.01), while the protein expressions of β-arrestin-2 and NF-κB p65 were significantly decreased (P<0.01). The amount of NF-κB p65 transferred from the extranuclear to the intranuclear decreased (P<0.01). ConclusionZJTP has a protective effect on HUVECs with high glucose and LPS-induced inflammatory injury, which may be related to the regulation of GPR43/β-arrestin-2/IκBα/NF-κB pathway.

Background::We previously reported that activation of the cell cycle in human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) enhances their remuscularization capacity after human cardiac muscle patch transplantation in infarcted mouse hearts. Herein, we sought to identify the effect of magnesium lithospermate B (MLB) on hiPSC-CMs during myocardial repair using a myocardial infarction (MI) mouse model.Methods::In C57BL/6 mice, MI was surgically induced by ligating the left anterior descending coronary artery. The mice were randomly divided into five groups ( n = 10 per group); a MI group (treated with phosphate-buffered saline only), a hiPSC-CMs group, a MLB group, a hiPSC-CMs + MLB group, and a Sham operation group. Cardiac function and MLB therapeutic efficacy were evaluated by echocardiography and histochemical staining 4 weeks after surgery. To identify the associated mechanism, nuclear factor (NF)-κB p65 and intercellular cell adhesion molecule-1 (ICAM1) signals, cell adhesion ability, generation of reactive oxygen species, and rates of apoptosis were detected in human umbilical vein endothelial cells (HUVECs) and hiPSC-CMs. Results::After 4 weeks of transplantation, the number of cells that engrafted in the hiPSC-CMs + MLB group was about five times higher than those in the hiPSC-CMs group. Additionally, MLB treatment significantly reduced tohoku hospital pediatrics-1 (THP-1) cell adhesion, ICAM1 expression, NF-κB nuclear translocation, reactive oxygen species production, NF-κB p65 phosphorylation, and cell apoptosis in HUVECs cultured under hypoxia. Similarly, treatment with MLB significantly inhibited the apoptosis of hiPSC-CMs via enhancing signal transducer and activator of transcription 3 (STAT3) phosphorylation and B-cell lymphoma-2 (BCL2) expression, promoting STAT3 nuclear translocation, and downregulating BCL2-Associated X, dual specificity phosphatase 2 (DUSP2), and cleaved-caspase-3 expression under hypoxia. Furthermore, MLB significantly suppressed the production of malondialdehyde and lactate dehydrogenase and the reduction in glutathione content induced by hypoxia in both HUVECs and hiPSC-CMs in vitro. Conclusions::MLB significantly enhanced the potential of hiPSC-CMs in repairing injured myocardium by improving endothelial cell function via the NF-κB/ICAM1 pathway and inhibiting hiPSC-CMs apoptosis via the DUSP2/STAT3 pathway.
