ABSTRACT

ObjectiveTo explore the molecular mechanism of Sanhuang Xiexintang (SHXXT) in protecting stress gastric ulcer (SGU) in rats through network pharmacology, molecular docking, and animal experiments. MethodThe active ingredients and corresponding targets in SHXXT were collected and screened from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Traditional Chinese Medicine Information Database (TCMID), Bioinformation Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM), and Swiss Target Prediction database. SGU-related targets were screened from the Online Mendelian Inheritance in Man (OMIM), Therapeutic Target Database (TTD), GeneCards database, and PharmGKB database. Herbal-ingredient-target (H-C-T) network was constructed by using Cytoscape 3.9.1 software. Protein-protein interaction (PPI) of drug and disease intersection targets was analyzed by using the Protein Interaction Platform (STRING) database. Gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were conducted through the Database for Annotation Visualization and Integrated Discovery (DAVID). The active ingredients and key targets were validated using AutodockVina 1.2.2 molecular docking software, and the experimental results were further validated through animal experiments. ResultThe 55 active ingredients were screened, and 255 potential target genes for SHXXT treatment of SGU were predicted. The PPI analysis showed that protein kinase B (Akt), phosphatase and tensin homolog deleted on chromosome ten (PTEN), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and cyclooxygenase-2 (COX-2) are the core targets of SHXXT for protecting SGU. GO and KEGG analyses showed that SHXXT may affect the development of SGU by regulating various biological processes such as the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway and inflammatory processes. The molecular docking results showed that both the active ingredients and key targets had good binding ability. Animal experiments showed that compared with the blank group, the ulcer index (UI) of the model group was significantly increased (P<0.01), and the serum levels of TNF-α and IL-1β significantly increased (P<0.01). The phosphorylation level of PTEN in gastric mucosal tissue was significantly down-regulated (P<0.05). The phosphorylation levels of PI3K, Akt, and nuclear factor kappa-B (NF-κB) were significantly up-regulated (P<0.05). Compared with the model group, the UI of the treatment group was significantly reduced (P<0.01), and the serum levels of TNF-α and IL-1β were significantly reduced (P<0.01). The phosphorylation level of PTEN in gastric mucosal tissue was significantly up-regulated (P<0.01), and the phosphorylation levels of PI3K, Akt, and NF-κB were significantly downregulated (P<0.01). ConclusionThe application of network pharmacology prediction, molecular docking simulation, and animal experimental validation confirms that SHXXT regulates the PI3K/Akt/NF-κB signaling pathway to regulate the inflammatory response of rats and thus protects the gastric mucosa of SGU rats.

ABSTRACT

ObjectiveTo investigate the impact of early intervention with Yishen Huazhuo prescription (YHP) on the learning and memory of accelerated aging model mice, as well as its underlying mechanism. MethodForty-eight 3-month-old male SAMP8 mice were randomly assigned into four groups, including the model group, low-dose YHP group, high-dose YHP group, and donepezil group. Additionally, 24 SAMR1 mice of the same age were divided into a control group and a YHP treatment control group, each consisting of 12 mice. The YHP groups received YHP at doses of 6.24 g·kg-1 and 12.48 g·kg-1, while the donepezil group was treated with donepezil at a dose of 0.65 mg·kg-1. The model group and control groups were given physiological saline. The mice were gavaged once daily for a duration of four weeks. Spatial learning and memory abilities of mice were assessed using the Morris water maze test. Immunofluorescence staining was employed to evaluate neuronal density as well as expression levels of M1 microglial (MG) polarization marker inducible nitric oxide synthase (iNOS) and M2 MG polarization marker arginase-1 (Arg-1) in the hippocampus region. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of pro-inflammatory factor interleukin 1β (IL-1β) and anti-inflammatory factor transforming growth factor-β1 (TGF-β1). Furthermore, Western blot analysis was conducted to determine expressions of amyloid β peptide1-42 (Aβ1-42) along with triggering receptor expressed on myeloid cells 2 (TREM2)/nuclear factor kappa B (NF-κB) signaling pathway-related proteins TREM2, phospho (p)-NF-κB p65, and phospho-inhibitory kappa B kinase β (IKKβ) in the hippocampus. ResultCompared with the control group, the model group exhibited a significantly prolonged escape latency (P<0.01), a significant reduction in neuron-specific nuclear protein (NeuN) expression in the hippocampus, a significant increase in iNOS expression in MG, and a significant decrease in Arg-1 expression. The serum IL-1β content was significantly increased, while the TGF-β1 content was significantly decreased. Additionally, there was a significant decrease in TREM2 expression in the hippocampus and significant increases in p-NF-κB p65, p-IKKβ, and Aβ1-42 expressions (P<0.05, P<0.01). However, no significant changes were observed in escape latency, times of crossing the platform, and hippocampal NeuN expression in the YHP treatment control group. Conversely, iNOS expression in MG as well as the hippocampal p-NF-κB p65, p-IKKβ, and Aβ1-42 expressions were significantly decreased. Furthermore, TREM2 expression was significantly increased (P<0.05, P<0.01). In comparison to the model group, the low-dose YHP group showed a significantly shortened escape latency and an increased number of crossing the platform (P<0.05, P<0.01). In the high-dose YHP group, the escape latency was significantly shortened (P<0.05). In the low-dose YHP group, high-dose YHP group, the expression of NeuN in the hippocampus was significantly increased, the expression of iNOS in MG was significantly decreased, and the expression of Arg-l was significantly increased. The serum IL-1β content was significantly decreased, while the TGF-β1 content was significantly increased. Furthermore, the expression of TREM2 in the hippocampus was significantly increased, and the expressions of p-NF-κB p65, p-IKKβ, and Aβ1-42 were significantly decreased (P<0.01). ConclusionEarly YHP intervention may promote the transformation of hippocampal MG from M1 to M2 by regulating the TREM2/NF-κB signaling pathway, reduce the release of neuroinflammatory factors, protect hippocampal neurons, and reduce the deposition of Aβ1-42, and finally delay the occurrence of learning and memory decline in SAMP8 mice.

ABSTRACT

OBJECTIVE To investigate the preferences of patients who underwent solid organ transplantation regarding therapeutic drug monitoring (TDM) of mycophenolic acid (MPA) and explore the factors influencing patients’ decision-making process, so as to provide support for the development of individualized medication guidelines for MPA and improvement of clinical decision-making. METHODS The cross-sectional study was used to design the questionnaire on the patients’ preferences to accept MPA TDM, and involved patients who underwent solid organ transplantation and received MPA treatment at two tertiary hospitals in Beijing from April 14, 2022, to June 27, 2022. The Likert 5-level scoring method was used to score the patients’ preferences to accept MPA TDM, the influencing factors and their correlation of the patients’ preferences to accept MPA TDM were analyzed by Pearson correlation analysis and binary Logistic regression analysis, and the nonparametric test and chi-square test were used to rank and analyze the consistency of the factors affecting patients’ preference decision. RESULTS A total of 140 questionnaires were collected, and the effective recovery rate was 77.35%. The average preference score of 140 patients to receive MPA TDM was (4.01±0.65), and the overall preference value was high. There were 116 (82.86%) patients agreed or strongly agreed with MPA TDM. Significant differences were observed in preference scores between patients who had previously undergone MPA TDM and those who had never undergone it ([ 4.30±0.53) scores vs. (3.80±0.65) scores, P<0.001]. Additionally, patients’ preference scores were significantly influenced by their understanding level and attention level (P<0.001). The ranking of factors contributing to decision-making exhibited consistency (P<0.001). The factors were ranked in descending order of clinical efficacy, safety, comfortability, economy and time cost. CONCLUSIONS The patients who underwent solid organ transplantation hold high preferences towards MPA TDM. The primary factors influencing their decisions are their prior experience, understanding level, and attention level.

ABSTRACT

OBJECTIVE@#To explore the interaction between Tubulin beta 4B class IVb (TUBB4B) and Agtpbp1/cytosolic carboxypeptidase- like1 (CCP1) in mouse primary spermatocytes (GC-2 cells) and the role of TUBB4B in regulating the development of GC-2 cells.@*METHODS@#Lentiviral vectors were used to infect GC-2 cells to construct TUBB4B knockdown and negative control (NC-KD) cells. The stable cell lines with TUBB4B overexpression (Tubb4b-OE) and the negative control (NC-OE) cells were screened using purinomycin. RT-qPCR and Western blotting were used to verify successful cell modeling and explore the relationship between TUBB4B and CCP1 expressions in GC-2 cells. The effects of TUBB4B silencing and overexpression on the proliferation and cell cycle of GC-2 cells were evaluated using CCK8 assay and flow cytometry. The signaling pathway proteins showing significant changes in response to TUBB4B silencing or overexpression were identified using Western blotting and immunofluorescence assay and then labeled for verification at the cellular level.@*RESULTS@#Both TUBB4B silencing and overexpression in GC-2 cells caused consistent changes in the mRNA and protein expressions of CCP1 (P < 0.05). Similarly, TUBB4B expression also showed consistent changes at the mRNA and protein after CCP1 knockdown and restoration (P < 0.05). TUBB4B knockdown and overexpression had no significant effect on proliferation rate or cell cycle of GC-2 cells, but caused significant changes in the key proteins of the nuclear factor kappa-B (NF-κB) signaling pathway (p65 and p-p65) and the mitogen-activated protein kinase (MAPK) signaling pathway (ErK1/2 and p-Erk1/2) (P < 0.05); CCP1 knockdown induced significant changes in PolyE expression in GC-2 cells (P < 0.05).@*CONCLUSIONS@#TUBB4B and CCP1 interact via a mutual positive regulation mechanism in GC-2 cells. CCP-1 can deglutamize TUBB4B, and the latter is involved in the regulation of NF-κB and MAPK signaling pathways in primary spermatocytes.

ABSTRACT

Femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)and small incision lenticule extraction(SMILE)are the mainstream corneal refractive surgeries at present. Despite efficacy, safety and predictability they have showed in refractive error correction, there are still complications relating to femtosecond laser, such as suction loss and opaque bubble layer(OBL), due to that the production of corneal flap or lenticule is dependent on the femtosecond laser. OBL is a complication that is unique to femtosecond laser surgery and the bubbles are generated from photo-disruptive effect towards corneal tissues which consisted of water vapor and carbon dioxide, and OBL gradually formed when the bubbles are trapped in the stroma. The bubbles can influence the intraoperative manipulation and postoperative visual quality. This review discusses the mechanism, grading, classification, and influencing factors of OBL and its effects on intraoperative manipulations and postoperative recovery, in the hope of providing reference and basis for further clinical studies.

ABSTRACT

Zuojinwan is a classic Chinese medicine prescription recorded in the Danxi's Experiential Therapy, with Coptidis Rhizoma and Euodiae Fructus in a ratio of 6 ∶ 1. It can treat symptoms such as liver fire hypochondriac pain, stomach duct pain, vomiting, and acid swallowing. There are many pharmacological studies on Zuojinwan in modern times, especially in the digestive tract, but the prescription also has its unique effect on digestive tract cancer, and its anti-tumor studies mainly focus on colorectal cancer and gastric cancer. Colorectal cancer is the third most common type of cancer in the world and the second deadliest malignancy. At present, a number of studies have shown that the basic pharmacological studies of anti-colorectal cancer by Zuojinwan include the proliferation, apoptosis, invasion, energy metabolism, epigenetics, and drug resistance of colorectal cancer. Alkaloids are the main active ingredients of Zuojinwan, such as berberine, evodiamine, coptisine, palmatine, and rutaecarpine. Compared with the effect of Zuojinwan on colorectal cancer, studies on the effect of berberine and evodiamine on tumor angiogenesis, tumor-promoting inflammation, and intestinal flora are carried out, except the studies on the resistance of berberine and the effect of evodiamine on energy metabolism. In addition, coptisine, palmatine, and rutaecarpine can regulate the proliferation, apoptosis, and metastasis of colorectal cancer cells, the proliferation and apoptosis of colorectal cancer cells, tumor-promoting inflammatory response, and the proliferation, migration, and invasion of colorectal cancer cells, respectively. Moreover, other studies have shown that the combination of berberine and evodiamine can have a synergistic effect on the growth, migration, and invasion of colorectal cancer cells and can reduce the cardiac toxicity induced by evodiamine. Therefore, this paper summarizes the studies on the anti-colorectal cancer mechanism of Zuojinwan and its main monomer components in recent years, so as to provide a theoretical basis for future clinical research and development of new high-efficiency and low-toxicity anti-colorectal cancer drugs and lay a solid foundation for clinical practice.

ABSTRACT

Objective:To analyze the clinical characteristics of elderly acute pulmonary thromboembolism(APE)patients complicated with preexisting atrial fibrillation(AF)and the impact of preexisting AF on in-hospital adverse outcomes in elderly patients with APE.Methods:A retrospective analysis was performed on elderly APE patients with preexisting AF hospitalized in Beijing Anzhen Hospital, Capital Medical University between January 1, 2008 and December 31, 2021.We compared the comorbidities, symptoms, signs, laboratory test results and echocardiographic features, simplified pulmonary embolism severity index(sPESI)scores and adverse in-hospital outcomes between the preexisting AF group and the non-AF group.Logistic regression was used to analyze the risk factors of in-hospital adverse outcomes in elderly patients with APE.Results:A total of 240 patients diagnosed with APE were enrolled.There were 120 patients in the AF group and 120 patients in the non-AF group.For patients in the AF group and the non-AF group, the proportions with chronic heart failure were 38.3%(46/120)and 15.8%(19/120), the proportions with lower extremity deep vein thrombosis(DVT)were 36.7%(44/120)and 65.8%(79/120), the left ventricular ejection fractions(LVEF)were(59±10)% and(62±7)%, and hospital stays were(15±7)and(11±4)days, respectively, and the differences were statistically significant( χ2=15.381, 20.429, t=2.527, -4.710, all P<0.05). The incidences of in-hospital adverse outcomes in the AF group and the non-AF group were 4.2%(5/120)and 3.3%(4/120), respectively, with no significant difference( χ2=0.000, P=1.000). The overall incidence of in-hospital adverse outcomes was 3.8%(9/240). Multivariate Logistic regression analysis showed that elevated lactic acid was an independent risk factor for in-hospital adverse outcomes( OR=2.753, 95% CI: 1.367-5.542, P=0.005). However, AF( OR=2.880, 95% CI: 0.587-14.141, P=0.192)and sPESI score( OR=2.056, 95% CI: 0.904-4.673, P=0.086)were not associated with in-hospital adverse outcomes. Conclusions:Elderly APE patients with preexisting AF have a relatively low incidence of DVT, but a higher proportion have concurrent chronic heart failure and need a longer hospital stay.Elevated lactic acid is an independent risk factor for in-hospital adverse outcomes of elderly APE patients with preexisting AF.However, preexisting AF has no predictive value for in-hospital adverse outcomes in elderly patients with APE.

ABSTRACT

Objective:To explore the pathogenesis of gallbladder cholesteryl polyps (GCP) and gallbladder cholesterol calculus (GCC) by studying the different changes of mucin (MUC) expression and reverse cholesterol transporter (RCT) in gallbladder mucosa epithelium.Methods:The data of 10 GCP patients (GCP group), 10 GCC patients (GCC group) and 5 patients with normal gallbladder resection (control group) were retrospectively analyzed, who underwent cholecystectomy in the Department of General Surgery, Xuanwu Hospital, Capital Medical University from January to December 2021. Among the 10 patients in the GCP group, there were 5 males and 5 females, aged (43.40±9.59) years old. Among the 10 patients in the GCC group, 5 males and 5 female, aged (45.00±8.13) years old. Among the 5 patients in the control group, there were 3 males and 2 females, aged (43.80±6.01) years old. Immunohistochemical analysis was used to investigate the expression differences of various subtypes of MUC and RCT [ATP binding cassette transporter G1 (ABCG1) and B group type I scavenger receptor (SR-BI)] among each group.Results:Compared with the control group, the expression of MUC1 (3.40±0.70 vs. 0), MUC5AC (1.50±0.53 vs. 0), MUC6 (4.70±0.48 vs. 0), and ABCG1 (3.50±0.53 vs. 1.60±0.55) in the gallbladder mucosa of the GCP group increased, while the expression score of SR-BI decreased (1.70±0.48 vs. 3.40±0.55), with statistical significance (all P<0.001). Compared with the control group, the expression of MUC1 (4.80±0.42 vs. 0), MUC5AC (4.70±0.48 vs. 0), MUC6 (3.30±0.67 vs. 0), and ABCG1 (3.40±0.52 vs. 1.60±0.55) in the gallbladder mucosa of the GCC group increased, while the expression score of SR-BI decreased (0 vs. 3.40±0.55), with statistically significant differences (all P<0.001). Conclusion:The different expression levels of MUC1, MUC5AC, MUC6, and RCT proteins lead to the differential formation of GCP and GCC on the basis of the co-pathogenesis in high cholesterol in bile.

ABSTRACT

Objective:To analyze the difference of clinical characteristics and outcomes of infants with moderate and severe pediatric acute respiratory distress syndrome(PARDS)diagnosed according to baseline oxygenation index(OI) in pediatric intensive care unit(PICU).Methods:Second analysis of the data collected from the "Efficacy of pulmonary surfactant (PS) in the treatment of children with moderate and severe ARDS" program.Retrospectively compare of the differences in clinical data such as general condition, underlying diseases, OI, mechanical ventilation, PS administration and outcomes among infants with moderate and severe PARDS divided by baseline OI who admitted to PICUs at 14 participating tertiary hospitals from 2016 to December 2021.Results:Among the 101 cases, 55 cases (54.5%) were moderate and 46 cases (45.5%) were severe PARDS.The proportion of male in the severe group (50.0% vs.72.7%, P=0.019) and the pediatric critical illness score(PCIS)[72 (68, 78) vs.76 (70, 80), P=0.019] were significantly lower than those in the moderate group, while there was no significant difference regarding age, body weight, etiology of PARDS and underlying diseases.The utilization rate of high-frequency ventilator in the severe group was significantly higher than that in the moderate group (34.8% vs.10.9%, P=0.004), but there was no significant difference in PS use, fluid load and pulmonary complications.The 24 h OI improvement (0.26±0.33 vs.0.04±0.34, P=0.001) and the 72 h OI improvement[0.34 (-0.04, 0.62) vs.0.15 (-0.14, 0.42), P=0.029)]in the severe group were significantly better than those in the moderate group, but there was no significant difference regarding mortality, length of hospital stay and intubation duration after diagnosis of PARDS between the two groups. Conclusion:In moderate and severe(divided by baseline OI) PARDS infants with invasive mechanical ventilation, children in severe group have better oxygenation improvement in the early stage after PARDS identified and are more likely to receive high frequency ventilation compared to those in moderate group.Baseline OI can not sensitively distinguish the outcomes and is not an ideal index for PARDS grading of this kind of patient.

ABSTRACT

Objective:Extracorporeal carbon dioxide removal(ECCO 2R) is a technique that aims to decarboxylate the blood and thus to correct hypercapnia and respiratory acidosis in acute respiratory failure, but is rarely used in children.We successfully completed the ECCO 2R treatment for a pediatric case with adenovirus pneumonia, severe acute respiratory distress syndrome(ARDS) and hypercapnia in PICU, which provided clinical references for the use of ECCO 2R in acute respiratory failure for children. Methods:A patient with adenovirus pneumonia and severe ARDS was successfully treated with ECCO 2R-continuous renal replacement therapy(CRRT)combined system after weaning from extracorporeal membrane oxygenation(ECMO). We reported the treatment process, ECCO 2R treatment effect and side effects, so as to provide clinical reference for ECCO 2R treatment of children with ARDS. Results:One-year and four-month-old boy was treated with mechanical ventilation and venous-arterial ECMO due to adenovirus pneumonia and severe ARDS.After ECMO treatment for 25 days, he developed severe hypercapnia after weaning from ECMO.ECCO 2R was initiated.The pH value increased by 11.2%(from 7.222 to 7.303) 1 hour after ECCO 2R treatment, partial pressure of blood carbon dioxide(PCO 2)decreased by 29.1%(from 72.6 mmHg to 51.5 mmHg, 1 mmHg=0.133 kPa) and the average airway pressure of high-frequency ventilation decreased by 5 cmH 2O(from 20 cmH 2O to 15 cmH 2O, 1 cmH 2O=0.098 kPa) after 6 hours of ECCO 2R.The CO 2 removal rate of ECCO 2R system was 29.1 mL/min.It was stopped because of ECCO 2R-membrane clotting after 72 h. There was no increase of PCO 2.Extubation was successfully after undergoing invasive mechanical ventilation for 39 days and with noninvasive ventilation for 5 days.The boy was hospitalized in PICU for 54 days, improved and discharged from the hospital.Followed up for 2 years after discharge, the growth and development were good, but the strenuous exercise endurance was still poor. Conclusion:ECCO 2R is effective in improving gas exchange, reducing PCO 2 and lowering ventilator pressure in children with ARDS and hypercapnia, which allow more protective ventilation.ECCO 2R provide transitional treatment for ECMO weaning and provide meaningful clinical reference for the use of ECCO 2R as part of respiratory support in children with respiratory failure.

ABSTRACT

Objective:To explore the current status and influencing factors of medical narrative competence among nurses in Luzhou, offering theoretical insights for improving nurses′ narrative competence.Methods:This study was a cross-sectional survey. From July 2021 to January 2022, using convenience sampling method, 267 nurses from Zhongshan Area of Affiliated Hospital of Southwest Medical University, Kangjian Area of Affiliated Hospital of Southwest Medical University and the Traditional Chinese Medicine Hospital Affiliated to Southwest Medical University were investigated by the general information questionnaire, Narrative Competence Scale, Nurses′ Perceived Professional Benefits Questionnaire And Perceived Social Support Scale.Results:The total scores of narrative competence of the 267 nurses was (142.25 ± 19.03), nurses′ perceived professional benefits was (137.16 ± 15.89) and perceived social support was (65.86 ± 10.38). The results of multiple linear regression showed that nurses′ perceived professional benefits and perceived social support were the important factors affecting their narrative ability ( t = 5.09 and 5.95, both P<0.05), which could account for 35.7% of the total variation of narrative competence. Conclusions:Nurses have narrative competence at low level in Luzhou. Managers should pay more attention to nurses who have poor level of perceived professional benefits and perceived social support, so as to keep the nurses′ mental health and improve nurses′ narrative competence by taking corresponding measures.

ABSTRACT

Objective:To evaluate the effect of scalp acupuncture combined with repeated transcranial magnetic stimulation (rTMS) on dysphagia after ischemic stroke.Methods:Prospective cohort study. A total of 94 patients with dysphagia after ischemic stroke in our hospital who met the inclusion criteria from December 2020 to February 2022 were randomly divided into two groups with 47 patients in each group. The control group was treated with rTMS and conventional acupuncture, while the scalp acupuncture group was treated with rTMS and scalp acupuncture (scalp acupuncture+seven points at the skull base). Both groups were treated for 4 weeks. Before and after treatment, Traditional Chinese Medicine (TCM) symptoms were scored, and the morphology, movement and food swallowing process of the patient's swallowing anatomy were observed with fiber optic endoscopy (FEES), and assessed by the leakage aspiration scale (PAS). The Yilang Fujishima swallowing efficacy evaluation and standard swallowing assessment (SSA) were used to evaluate swallowing function. The dysphagia quality of life scale (SWAL-QOL) were used to evaluate patients' quality of life. Magnetic resonance diffusion tensor imaging (DTI) scanning was performed to observe the anisotropy fraction (FA value) of the selected region of interest (ROI).Results:During the treatment period, each group dropped off 1 patient, and 92 patients entered the statistics. After treatment, the scores of salivation, food retention, eating and drinking cough in the scalp acupuncture group were significantly lower than those in the control group ( t values were 6.87, 4.90, 5.01, respectively, P<0.01), and the PAS grading was significantly better than that in the control group ( χ2=7.80, P=0.025), the swallowing efficacy evaluation and SWAL-QOL score of Yilang Fujishima were significantly higher than those of the control group ( t=6.81, 5.98, P<0.01), and the SSA score was significantly lower than that of the control group ( t=5.68, P<0.01). The FA values of parieto occipital cortex (0.47 ± 0.06 vs. 0.42 ± 0.04, t=3.16), insular cortex (0.44 ± 0.07 vs. 0.40 ± 0.05, t=3.00) and posterior limb of internal capsule (0.58 ± 0.04 vs. 0.54 ± 0.05, t=2.80) of ROI in the head acupuncture group after treatment were significantly higher than those in the control group ( P<0.05). Conclusion:The scalp acupuncture combined with rTMS can improve the swallowing function of patients with dysphagia after ischemic stroke and improve their quality of life.

ABSTRACT

{L-End}Objective To analyze the effects of night shift work and overweight/obesity on blood pressure of workers in chemical fiber industry. {L-End}Methods A total of 1 004 workers of a chemical fiber factory were selected as the study subjects using convenient sampling method, and their blood pressure and body mass index were measured. Multiple linear regression model was used to analyze the relationship between night shift work and blood pressure, and multiple logistic regression was used to assess the independent impact and combined impact of night shifts and overweight/obesity on the risk of hypertension. {L-End}Results Compared with the non-night shift workers, the prevalence of hypertension in night shift workers was increased (5.3% vs 13.0%, P<0.05), with elevated systolic and diastolic blood pressure (both P<0.05). The results of multiple linear regression analysis showed that the systolic blood pressure and diastolic blood pressure of the night shift workers were higher than those of the non-night shift workers (both P<0.05), and the systolic blood pressure and diastolic blood pressure of overweight/obesity workers were higher than those of non-overweight/obesity workers (both P<0.01). The results of multiple logistic regression analysis showed that the risk of hypertension in night shift workers and overweight/obesity workers was higher than that in non-night shift workers and non-overweight/obesity workers [odds ratio (OR) and 95% confidence interval (CI) were 2.49 (1.04-5.99) and 2.65 (1.77-3.95), both P<0.05]. Night shift work and overweight/obesity showed a synergistic effect on blood pressure of workers. Compared to non-overweight/obesity non-night shift workers, overweight/obesity night shift workers had a higher risk of hypertension (OR=4.93, 95%CI: 1.70-14.29, P<0.01). {L-End}Conclusion Night shift work could lead to elevated blood pressure in workers in the chemical fiber industry, which is a potential risk factor for hypertension. The synergistic effect of night shift work and overweight/obesity may contribute to the increased risk of hypertension.

ABSTRACT

Objective To investigate the ability of combined baseline serum markers, i.e., HBV DNA, HBV RNA, HBsAg, and HBcrAg, to predict HBeAg seroconversion in patients with HBeAg-positive chronic hepatitis B (CHB) treated by nucleos(t)ide analogues. Methods A retrospective analysis was performed for 83 HBeAg-positive patients selected as subjects from the prospective CHB follow-up cohort established by Difficult & Complicated Liver Diseases and Artificial Liver Center, Beijing YouAn Hospital, Capital Medical University, from June 2007 to July 2008, and the baseline serum levels of HBV DNA, HBV RNA, HBsAg, and HBcrAg were analyzed. The t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The Spearman method was used for correlation analysis. A Cox regression model was established to calculate HBeAg seroconversion prediction score, and the time-dependent receiver operating characteristic curve was used to evaluate the ability of combined markers in predicting HBeAg seroconversion. The Kaplan-Meier method was used to calculate cumulative seroconversion rate in each group, and the Log-rank test was used for comparison between groups. Results For the 83 HBeAg-positive patients, the median follow-up time was 108 months, and 44.58%(37/83) of these patients achieved HBeAg seroconversion. Compared with the non-seroconversion group, the HBeAg seroconversion group had significantly lower baseline serum levels of HBV DNA [6.23(1.99-9.28) log 10 IU/mL vs 7.69(2.05-8.96) log 10 IU/mL, Z =-2.345, P =0.019] and HBV RNA [4.81(1.40-7.53) log 10 copies/mL vs 6.22(2.00-8.49) log 10 copies/mL, Z =-1.702, P =0.010], and there were no significant differences in the levels of HBsAg and HBcrAg between the two groups ( P > 0.05). The Cox regression equation constructed based on the above serum markers showed a median score of 0.95(range 0.37-3.45) for predicting HBeAg seroconversion. In the total population, the combined score was negatively correlated with HBsAg, HBV DNA, HBV RNA, and HBcrAg ( r =-0.697, -0.787, -0.990, and -0.819, all P < 0.001). Based on the median prediction score, the patients were divided into high HBeAg seroconversion group and low HBeAg seroconversion group; as for the prediction of HBeAg seroconversion rate at 36, 60, and 84 months, the high HBeAg seroconversion group had a seroconversion rate of 43.90%, 51.20%, and 63.10%, respectively, while the low HBeAg seroconversion group had a seroconversion rate of 9.60%, 17.00%, and 19.8%, respectively, and there was a significant difference between the two groups ( χ 2 =11.6, P < 0.001). Conclusion The combined prediction score based on baseline serum HBV markers can predict HBeAg seroconversion in CHB patients treated by nucleos(t)ide analogues.

ABSTRACT

OBJECTIVE@#To investigate the effect of midazolam on pain in lumbar disc herniation model rats based on p38 MAPK signaling pathway.@*METHODS@#Fifty SPF-grade Sprague-Dawley healthy rats, half male and half female, were selected and randomly divided into normal group, model group, and low-dose, medium-dose, high-dose groups. Model group and low-dose, medium-dose, high-dose groups were initially modeled for lumbar disc herniation. Intraperitoneal injection of saline was performed in rats of normal and model groups; and in the low-dose, medium-dose, and high-dose groups, intraperitoneal injection of midazolam was performed with doses of 30, 60, and 90 mg/kg, respectively. Interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), 5-hydroxytryptamine (5-HT), β-endorphin (β-EP), substance P (SP), neuropeptide Y (NPY) were detected in the serum of rats by enzyme-linked immunoassay. The expression of p38 MAPK and matrix metalloproteinase-3(MMP-3) protein were detected by Western blot in the tissues of rats of each group.@*RESULTS@#The levels of TNF-α, IL-1β and β-EP were higher and the level of 5-HT was lower in the model group than in the normal group(P<0.05);the levels of TNF-α, IL-1β and β-EP were lower and the level of 5-HT was higher in the low-dose, medium-dose and high-dose groups than in the model group(P<0.05). The levels of SP and NPY increased in the model group compared with the normal group (P<0.05) and the levels of SP and NPY decreased in the low-dose, medium-dose and high-dose groups compared with the model group (P<0.05). The expression of p38 MAPK and MMP-3 increased in the model group compared with the normal group (P<0.05); the expression of p38 MAPK and MMP-3 decreased in the low-dose, medium-dose and high-dose compared with the model group(P<0.05).@*CONCLUSION@#Midazolam may ameliorate the immune inflammatory response in rats with a model of lumbar disc herniation, possibly regulated through the p38MAPK signaling pathway.

ABSTRACT

Objective To explore the optimal parameters for virtual mono-energetic imaging of liver solid lesions. Methods A retrospective analysis was performed on 60 patients undergoing contrast-enhanced spectral CT of the abdomen.The iodine concentration values of hepatic arterial phase images and the CT values of different mono-energetic images were measured.The correlation coefficient and coefficient of variation were calculated. Results The average correlation coefficients between iodine concentrations and CT values of hepatic solid lesion images at 40,45,50,55,60,65,and 70 keV were 0.996,0.995,0.993,0.989,0.978,0.970,and 0.961,respectively.The correlation coefficients at 40(P=0.007),45(P=0.022),50 keV (P=0.035)were higher than that at 55 keV,and the correlation coefficients at 40 keV(P=0.134) and 45 keV(P=0.368) had no significant differences from that at 50 keV.The coefficients of variation of the CT values at 40,45,and 50 keV were 0.146,0.154,and 0.163,respectively. Conclusion The energy of 40 keV is optimal for virtual mono-energetic imaging of liver solid lesions in the late arterial phase,which is helpful for the diagnosis of liver diseases.

ABSTRACT

Eosinophilic gastroenteritis (EGE) is a gastrointestinal disorder of unclear etiology that is characterized by eosinophilic infiltration of the stomach and small intestine, and consists of mucosal, muscular, and serosal subtypes. Eosinophilic infiltration of the gastrointestinal tract is a fundamental histopathological characteristic of EGE and is driven by several T-helper type 2 (Th2)-dependent cytokines and induced by food allergy. Due to the lack of a diagnostic gold standard, EGE has a high rate of delayed diagnosis or misdiagnosis. However, several new diagnostic strategies have been developed, such as novel genetic biomarkers and imaging tests. Although dietary therapy and corticosteroids remain the common choices for EGE treatment, recent decades have seen the emergence of novel treatment alternatives, such as biologics that target particular molecules involved in the pathogenic process. Preliminary investigations and clinical trials have demonstrated the efficacy of biologics and provided additional insights for the era of refractory or corticosteroid-dependent EGE biologics.

ABSTRACT

BACKGROUND@#LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.@*METHODS@#We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.@*RESULTS@#On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).@*CONCLUSION@#LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT04563936.

ABSTRACT

Portal vein thrombosis (PVT) is one of the common complications of liver cirrhosis and is associated with the poor prognosis of liver disease. Rivaroxaban, a novel direct oral anticoagulant, exerts an antithrombotic effect by directly acting on the active center of factor Xa to inhibit the generation of thrombin, and it is a new choice for long-term anticoagulant treatment of PVT in liver cirrhosis with the advantages of direct oral administration and no need for international normalized ratio (INR) monitoring. In recent years, more and more clinical studies have shown that rivaroxaban is relatively safe and effective in the treatment of PVT in liver cirrhosis; however, there is still little experience in the application of rivaroxaban in the treatment of PVT in liver cirrhosis in the current clinical practice, and individualized medication regimen remains to be clarified. This article reviews the research advances in rivaroxaban in the treatment of PVT in liver cirrhosis, in order to provide new ideas for the clinical treatment of PVT in liver cirrhosis.

ABSTRACT

OBJECTIVE To develop an individualized medication list for elderly patients by evidence-based pharmacy method, and to support clinical decisions on rational use of METHODS Firstly, drugs with risk genetic information were screened out by systematically reviewing evidence-based pharmacy information. Secondly, researchers investigated the included drugs in lists from different data E- sources. Drugs included in three or more data sources and drugs proposed by the expert committee were then included in the medication list. Thirdly, for the drugs included in two data sources, researchers designed questionnaires to investigate the necessity of drug-related gene testing. According to the scoring results of the expert questionnaire, drugs with higher scores were included in the list. Data sources included real-world data (list of high frequency medication in hospitals, high frequency medication for elderly outpatients and inpatients in National Health Care Claims Data, drugs related to frequent medication errors and so on) and evidence-based pharmacy evidence (the websites of Clinical Pharmacogenomics Implementation Consortium, Dutch Pharmacogenetics Working Group, Food and Drug Administration and so on). RESULTS The study obtain 68 drugs with risk genetic information which were included in three data sources. Combined with 23 drugs proposed by the expert committee, a list containing 74 drugs was preliminarily formed after de-duplication. A total of 37 drugs included in two databases with risk genetic information were scored through the questionnaire survey to form a supplementary list of 26 drugs. This is the final composition of the list of 100 drugs developed in this study. Among them, there are 43 drugs for the central nervous system, 15 drugs for the cardiovascular system, 12 anti-tumor drugs and so on. Twelve drugs were included in six or more data sources, which mainly consisted of drugs for digestive system, all proton pump inhibitors. CONCLUSION In this study, a list of 100 commonly used drugs which require individualized medication for the elderly was developed by evidence-based pharmacy method. The drug list will be updated in time as available evidence changes, and can provide guidance for rational use of medicines for elderly patients.
