ABSTRACT

BACKGROUND@#Transcription factor (TF) can bind specific sequences that either promotes or represses the transcription of target genes, and exerts important effects on tumorigenesis, migration, invasion. Staphylococcal nuclease-containing structural domain 1 (SND1), which is a transcriptional co-activator, is considered as a promising target for tumor therapy. However, its role in lung adenocarcinoma (LUAD) remains unclear. This study aims to explore the role of SND1 in LUAD.@*METHODS@#Data from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), Clinical Proteomic Tumor Analysis Consortium (CPTAC), and Human Protein Atlas (HPA) database was obtained to explore the association between SND1 and the prognosis, as well as the immune cell infiltration, and subcellular localization in LUAD tissues. Furthermore, the functional role of SND1 in LUAD was verified in vitro. EdU assay, CCK-8 assay, flow cytometry, scratch assay, Transwell assay and Western blot were performed.@*RESULTS@#SND1 was found to be upregulated and high expression of SND1 is correlated with poor prognosis of LUAD patients. In addition, SND1 was predominantly present in the cytoplasm of LUAD cells. Enrichment analysis showed that SND1 was closely associated with the cell cycle, as well as DNA replication, and chromosome segregation. Immune infiltration analysis showed that SND1 was closely associated with various immune cell populations, including T cells, B cells, cytotoxic cells and dendritic cells. In vitro studies demonstrated that silencing of SND1 inhibited cell proliferation, invasion and migration of LUAD cells. Besides, cell cycle was blocked at G1 phase by down-regulating SND1.@*CONCLUSIONS@#SND1 might be an important prognostic biomarker of LUAD and may promote LUAD cells proliferation and migration.

ABSTRACT

Background Air quality health index (AQHI) is derived from exposure-response coefficients calculated from air pollution and morbidity/mortality time series, which helps to understand the overall short-term health impacts of air pollution. Objective To study the effects of common air pollutants on respiratory diseases in Urumqi and to develop an AQHI for the risk of respiratory diseases in the city. Methods The daily outpatient volume data of respiratory diseases from The First Affiliated Hospital of Xinjiang Medical University, meteorological data (daily mean temperature and daily mean relative humidity), and air pollutants [fine particulate matter (PM2.5), inhalable particulate matter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon dioxide (CO), and ozone (O3)] in Urumqi City, Xinjiang, China were collected from January 1, 2017 to December 31, 2021. A distributed lag nonlinear model based on quasi-Poisson distribution was constructed by time-stratified case crossover design. Adopting zero concentration of air pollutants as reference, the exposure-response coefficient (β value) was used to quantify the impact of included air pollutants on the risk of seeking medical treatment for respiratory diseases, and the AQHI was established. The association of between AQHI and the incidence of respiratory diseases and between air quality index (AQI) and the incidence of respiratory diseases was compared to evaluate the prediction effect of AQHI. Results Each 10 µg·m−3 increase in PM10, SO2, NO2, and O3 concentrations presented the highest excess risk of seeking outpatient services at 3 d cumulative lag (Lag03) and 2d cumulative lag (Lag02), with increased risks of morbidity of 0.687% (95%CI: 0.101%, 1.276%), 17.609% (95%CI: 3.253%, 33.961%), 13.344% (95%CI: 8.619%, 18.275%), and 4.921% (95%CI: 1.401%, 8.502%), respectively. There was no statistically significant PM2.5 or CO lag effect. An AQHI was constructed based on a model containing PM10, SO2, NO2, and O3, and the results showed that the excess risk of respiratory disease consultation for the whole population, different genders, ages, or seasons for each inter-quartile range increase in the AQHI was higher than the corresponding value of AQI. Conclusion PM10, SO2, NO2, and O3 impact the number of outpatient visits for respiratory diseases in Urumqi, and the constructed AQHI for the risk of respiratory diseases in Urumqi outperforms the AQI in predicting the effect of air pollution on respiratory health.

ABSTRACT

Objective To explore the research progress, research hotspot and development trend of tigecycline resistance based on the quantitative analysis and visualization function of CiteSpace. Methods The data were collected from 4,263 Chinese and English articles on tigecycline resistance in CNKI, Wanfang, VIP and Web of Science (WOS) databases from 2012 to 2022. CiteSpace 5.8.R3 software was used to analyze the cooperative network of authors, the cooperative network of countries and institutions, the total citation times of journals, and keywords included in the literature, to reveal the hotspots and trends of tigecycline resistance research. Results The number of articles published in English literature was higher than that in Chinese literature. China had the largest number of published documents, showing a significant international academic influence in this research field. Countries all over the world were concerned about the resistance of tigecycline, but Chinese literatures focused more on the clinical infection and prevention of tigecycline resistance, while English literatures placed special emphasis on the research about the drug resistance mechanism of tigecycline. Conclusion The research direction at home and abroad is basically the same, but the research focus has gradually shifted from the clinical treatment and monitoring of tigecycline to the molecular level of drug resistance mechanism.

ABSTRACT

ObjectiveTo establish and evaluate a chronic obstructive pulmonary disease (COPD) model with lung-spleen qi deficiency. MethodA rat model mimicking COPD with lung-spleen qi deficiency was established by the combination of cigarette smoking and intratracheal instillation of lipopolysaccharide (LPS) along with gavage of Sennae Folium infusion. Forty male SPF-grade SD rats were randomly assigned to blank, model, and low- (L-FXY), medium- (M-FXY), and high-dose (H-FXY) Sennae Folium infusion groups. Other groups except the blank group were exposed to daily cigarette smoke, with LPS administrated via intratracheal instillation on the 1st and 14th days. On the 28th day of modeling, the L-FXY, M-FXY, and H-FXY groups were administrated with Sennae Folium infusion at 5, 10, and 20 g·kg-1, respectively, and at 4 ℃ for three weeks. The modeling lasted for 49 days. The general conditions (body mass, food intake, fecal water content, and anal temperature) and behaviors (grip strength test and tail suspension test) of rats in different groups were examined. The lung function, lung histopathology, D-xylose, amylase, and gastrin levels in the serum, interleukin(IL)-1β and IL-6 levels in the alveolar lavage fluid, levels of T-lymphocyte subsets (CD4+, CD8+, and CD4+/CD8+) in the peripheral blood, and thymus and spleen indices were measured. ResultTwo rats died in the H-FXY group. Compared with the blank group, both the M-FXY and H-FXY groups exhibited reduced body mass and food intake (P<0.01) and increased fecal water content (P<0.01). The anal temperature in the H-FXY group was lower than that in the blank group (P<0.01). The grip strength decreased in the modeling groups compared with the blank group (P<0.01), and the duration of immobility in the tail suspension test increased in the M-FXY and H-FXY groups (P<0.05, P<0.01). Compared with the blank group, the modeling groups showed reduced 0.3 second forced expiratory volume (FEV0.3), FEV0.3/forced vital capacity (FVC)(P<0.01), thickening of bronchial walls, proliferation of goblet cells, and the presence of emphysematous changes. In terms of gastrointestinal function, the M-FXY and H-FXY groups had lower levels of D-xylose, gastrin, and α-amylase than the blank group (P<0.01). Regarding the immune and inflammatory indices, the M-FXY and H-FXY groups showed lower thymus and spleen indices than the blank group (P<0.01). Compared with the blank group, the modeling groups presented lowered CD4+ level (P<0.01) and CD4+/CD8+ ratio (P<0.05, P<0.01) in the peripheral blood and elevated levels of IL-1β and IL-6 in the alveolar lavage fluid (P<0.01) than the blank group. ConclusionA model of COPD with lung-spleen Qi deficiency was established through the combination of daily cigarette smoke, intratracheal instillation with LPS, and gavage of Sennae Folium infusion. The comprehensive evaluation results suggested medium-dose (10 g·kg-1) Sennae Folium infusion for gavage during the modeling of COPD with lung-spleen Qi deficiency.

ABSTRACT

Objective:To construct a prediction model for difficult tracheal intubation in the patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods:A total of 324 patients with OSAHS undergoing surgery with general anesthesia, admitted to our hospital from June 2019 to June 2021, were included in model group, and 175 patients with OSAHS undergoing surgery with general anesthesia, admitted from July 2021 to July 2022, were selected and served as validation group. The patients in model group were divided into occurrence group and non-occurrence group according to whether difficult tracheal intubation occurred. Logistic regression was used to construct the prediction model, and R4.2.1 software was used to draw the risk nomogram and calibration curve. The predictive accuracy of the model was evaluated by the area under the receiver operating characteristic curve.Results:Body mass index (BMI), sagittal minimum cross-sectional area, horizontal minimum cross-sectional area and mandibular distance were risk factors for difficult tracheal intubation in OSAHS patients ( P<0.05). A prediction model was developed using the above factors: Logit P=33.726+ 1.411×BMI score-0.014×sagittal airway minimum cross-sectional area-0.013×airway horizontal minimum cross-sectional area-0.312× mandibular distance. The area under the receiver operating characteristic curve was 0.846, Youden index 0.585, sensitivity 0.831, specificity 0.755, and the accuracy 0.889 (Hosmer-Lemeshow test χ2=9.24, P=0.322) in model group. The area under the external validation curve was 0.802, Youden index 0.545, sensitivity 0.636, specificity 0.908, and the accuracy 0.893 (Hosmer-Lemeshow test χ2=10.24, P=0.287) in validation group. Conclusions:The prediction model based on BMI, sagittal minimum cross-sectional area of airway, horizontal minimum cross-sectional area of airway and mandibular distance has a high value in predicting the risk of difficult tracheal intubation in patients with OSAHS.

ABSTRACT

Objective:To analyze the correlation between chronic obstructive pulmonary disease (COPD) and cognitive dysfunction.Methods:This is a case-control study. From February 2022 to October 2022, 32 COPD patients (inpatient and outpatient) from the Department of Respiratory and Critical Care Medicine and Rehabilitation Medical Center of the First Affiliated Hospital of Nanjing Medical University and 32 healthy subjects were recruited. All participants underwent a thorough evaluation, which included Montreal Assessment of Cognitive Function (MoCA), visuospatial n-back task included accuracy (ACC) and mean response time (RT), the pulmonary functions including forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1), one-second rate (FEV 1/FVC) and maximum volume per minute (MVV), Health Survey Short Form (SF-36), and St. George′s Respiratory Questionnaire (SGRQ). The correlation between cognitive dysfunction and lung function, SF-36 and SGRQ in COPD patients were analyzed. Results:The prevalence of smoking, hypertension and cardiovascular disease in the two groups were significantly different (all P<0.05). MoCA score, 1-back ACC and 2-back ACC in COPD group were significantly lower than those in healthy control group [(23.86±4.50) vs (27.55±1.29) points, (76.82%±16.60%) vs (90.61%±7.40%), (67.93%±10.10%) vs (78.74%±10.38%), all P<0.001]; 2-back RT was significantly higher than that of healthy group [(316.43±108.17) vs (254.09±101.62) ms, P<0.05]; and the Physiological function (PF), physiological function (RP), emotional function (RE), energy (VT), social function (SF), physical pain (BP) in SF-36 were significantly worse than the healthy control group (all P<0.05). The MoCA score of COPD group was positively correlated with FEV 1/FVC ( r=0.501, P=0.018). The 1-back ACC was positively correlated with FEV 1 and FEV 1/FVC ( r=0.568, 0.634; both P<0.05). The 1-back RT was negatively correlated with FEV 1/FVC and MVV ( r=-0.452, -0.534; both P<0.05). The 2-back ACC was positively correlated with FEV 1/FVC ( r=0.426, P=0.048). The 2-back RT was negatively correlated with MVV ( r=-0.571, P=0.006). In COPD group, MoCA score was negatively correlated with activity, influence and total score in SGRQ ( r=-0.533, -0.466, -0.521; all P<0.05). The 1-back ACC was negatively correlated with activity, influence and total score ( r=-0.552, -0.517, -0.584; all P<0.05). The 1-back RT was positively correlated with activity, influence and total score ( r=0.430, 0.379, 0.417; all P<0.05). The 2-back ACC was negatively correlated with impact and total score ( r=-0.398, -0.412; both P<0.05). Conclusion:COPD patients have impaired cognitive function, which is mainly manifested by the decline of working memory and executive function, and is correlated with the lung function, general health condition and quality of life.

ABSTRACT

Objective:To investigate the value of radiomics based on three-dimensional high resolution MR vessel wall imaging (3D HRMR-VWI) for identifying culprit plaques in symptomatic patients with middle cerebral atherosclerosis.Methods:The clinical and imaging features of 117 patients (139 middle cerebral artery plaques) with cerebrovascular diseases in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from October 2018 to October 2020 were respectively reviewed. Stratified random sampling was used to divide 139 plaques into training set (97 plaques) and validation set (42 plaque) at the ratio of 7∶3. The plaques were divided into 69 culprit plaques and 70 non-culprit plaques based on plaque MR features and clinical symptoms. The clinical and imaging characteristics of culprit plaques and non-culprit plaques were compared by independent sample t-test, Mann-Whitney U test and χ 2 test, and factors with significant difference between two groups in univariate analysis were further analyzed by multivariate logistic regression to find out the independent predictors of culprit plaques. Radiomics features were extracted, screened and radiomics model was constructed using pre-and post-contrast 3D HRMR-VWI based on the training set. The combined model was constructed by combining the independent predictors and radiomics model. Receiver operating characteristic curve and area under curve (AUC) were used to evaluate the efficacy of each model, and DeLong test was used to compare the efficacy of different models. Results:Significant difference was found in intraplaque hemorrhage, lumen area of stenosis, stenosis diameter, stenosis rate, plaque burden and enhancement rate between culprit and non-culprit plaques (all P<0.05). Multivariate logistic regression analysis confirmed that only intraplaque hemorrhage was the independent predictor for culprit plaques (OR=7.045,95%CI 1.402-35.397, P=0.018). In the validation set, the AUC of the pre-contrast 3D HRMR-VWI model was lower than that of the post-contrast 3D HRMR-VWI model ( Z=-2.01, P=0.044). The AUC of pre+post-contrast 3D HRMR-VWI model was not significantly different from that of post-contrast 3D HRMR-VWI model ( Z=0.79, P=0.427). The AUC showed no significant difference between combined model and pre+post-contrast 3D HRMR-VWI model ( Z=-0.59, P>0.05). The combined model showed the best performance in predicting culprit plaques of middle cerebral artery (AUC=0.939), with the sensitivity, specificity and accuracy of 95.24%, 76.19% and 85.71%. Conclusion:Radiomics based on 3D HRMR-VWI has potential values in identifying culprit plaques in symptomatic patients with middle cerebral atherosclerosis.

ABSTRACT

Objective:To design an anatomical plate of ulna coronoid process using 3D printing and computer model design software based on a collection of CT scanning data of the ulna coronoid process.Methods:The CT scans of the elbow joint with no obvious anatomic variation, no fracture, or no history of elbow operation were collected which had been taken at Trauma Center, The First Affiliated Hospital of Kunming Medical University from September 2017 to January 2022. There were 52 males and 50 females. RadiAnt DICOM Viewer and Mimics Medical 21.0 were used to visualize the CT data of the elbow joint of 102 volunteers. The software was used to measure the angle between the tip of the ulna coronoid process and the tuberosity of the ulna, the width at 1/2 height of the ulna coronoid process, the distance between the tip of the ulna coronoid process and the horizontal plane of the ulna tuberosity, and the safety angle for screw placement. After the values were measured, Siemens Ungraphics NX12.0 software was used to design the anatomical plate and the screw guide device of the ulna coronoid process. After the plate model was designed, a 1:1 actual plate model of the ulna coronoid process was produced by 3D printing. The actual plate model was placed onto an adult model of the ulna coronoid process and an adult cadaveric specimen of the ulna coronoid process to verify its matching degree. An in vitro operation was simulated using the plate model to verify its operability. Results:There were no significant differences between the left and right sides in the angle between the tip of the ulna coronoid process and the tuberosity of the ulna, the width at 1/2 height of the ulna coronoid process, the distance between the tip of the ulna coronoid process and the horizontal plane of the ulna tuberosity, or the safety angle for screw placement in either males or females ( P>0.05). There were no significant differences between males and females in the angle between the tip of the ulna coronoid process and the tuberosity of the ulna or in the safety angle for screw placement ( P>0.05). There were statistically significant differences between males and females in the width of 1/2 height of the ulna coronoid process and the distance between the tip of the ulna coronoid process and the horizontal plane of the ulna tuberosity ( P<0.05). However, the experiments on computer simulative adaptation and plate model simulative adaptation found that the anatomical plates of the ulna coronoid process designed on various parameters of males and females were exchangeable, leading to similarly good marching degrees and safe angles for screw placement. Conclusions:The anatomical plate of the ulna coronoid process designed in this study demonstrates a good fit and a safe angle for screw placement, basically achieving the goal expected to provide a basis for fabrication of a titanium alloy plate. In design of an anatomical plate of ulna coronoid process, it is not necessary to differentiate males from females or to differentiate the left side from the right one, because only a general plate can be used for both males and females and for both the left and the right sides.

ABSTRACT

OBJECTIVE Temporal lobe epilepsy is a common neurological disease caused by abnormal syn-chronized discharge in the brain and it is mainly treated through long-term use of anti-epileptic drugs(AEDs).This project is supposed to provide an electro-responsive and brain-targeted drug delivery system(DDS)for on-demand drug release,which could promptly block the transmis-sion of epileptic discharges.METHODS The DDS was fab-ricated by co-polymerization of dopamine and pyrrole,together with conjugation of brain-targeted peptide.A number of characterization including electron microscopy,thermogravimetric analysis,dynamic light scattering and other methods were conducted to evaluate the physio-chemical properties of the nanomaterials.In vitro study based on a home-made electric device and high perfor-mance liquid chromatography was performed to record drug release profiles.Three epileptic models including acute,continuous and spontaneous models were estab-lished for the evaluation of therapeutic efficacy.RESULTS Our polymeric DDS has a nanoscale size(ca.80 nm)and could load AEDs such as phenytoin(drug loading capacity 20.4%).The hybrid nanomaterials can improve the brain delivery efficiency through a combination of receptor-mediated transcytosis and near-infrared-enabled brain transport.In vitro study proved that the DDS could release phenytoin in the electric field in a sensitive(50 μA),quick(30 s)and sustained(>3 times)manner.In vivo study demonstrated excellent anti-epileptic effects in a lower dose(20%).Biosafety study further verified that our strategy has limited damage.CONCLUSION For on-demand seizure control,we have developed a nano-engineered DDS with the capability of electro-responsive drug release and brain-targeted accumula-tion.The DDS could increase the AEDs accumulation at epileptic region and release the AEDs in response to the epileptic discharges.Such strategy could timely inhib-it the epileptic seizure.Our work provides a promising approach to"smart"therapy of epilepsy and sheds light on development of pharmacotherapy of other brain disorders.

ABSTRACT

Objective:To investigate the value of LASSO regression prediction of lymph nodes around hepatic artery metastasis based on blood routine index in patients with distant gastric cancer.Methods:The clinical data of 110 patients with distant gastric cancer from June 2018 to February 2022 in Jieshou People′s Hospital were retrospective analyzed. Among them, 43 patients had lymph nodes around hepatic artery metastases (metastasis group), and 67 patients have not lymph nodes around hepatic artery metastases (non-metastasis group). The basic clinical data were recorded; the routine blood test was detected, the indexes including white blood cell count, neutrophil percentage, lymphocyte count, platelet count, lymphocyte percentage, acidophil count, basophils count, hemoglobin, red blood cell distribution width (RDW), platelet distribution width (PDW) and neutrophil to lymphocyte ratio (NLR). The R language 4.1.0 software "grpreg" package was used to establish a Group LASSO Logistic regression analysis model to finally select the factors predicting lymph node around hepatic arterial metastasis in patients with distal gastric cancer. Nomogram were made using R language 3.5.3 software package and rms program package, calculated the consistency index (C-index), and the accuracy of the model was evaluated by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve.Results:The white blood cell count, neutrophil percentage, NLR and lymphocyte percentage in metastasis group were significantly higher than those in non-metastasis group: (12.16 ± 1.62) × 10 9/L vs. (9.38 ± 2.64) × 10 9/L, (73.36 ± 6.94)% vs. (52.21 ± 6.23)%, 3.23 ± 0.63 vs. 2.35 ± 0.13 and (48.62 ± 3.64)% vs. (31.02 ± 2.94)%, the acidophil count and basophils count were significantly lower than those in non-metastasis group: (0.31 ± 0.03) × 10 9/L vs. (0.36 ± 0.04) × 10 9/L and (0.08 ± 0.01) × 10 9/L vs. (0.09 ± 0.02) × 10 9/L, the degree of differentiation and TNM stage were also worse than those in non-metastasis group, and there were statistical differences ( P<0.01). The nomogram was constructed to predict lymph nodes around hepatic artery metastasis based on the degree of differentiation, TNM stage, white blood cell count, neutrophil percentage, NLR, lymphocyte percentage, acidophil count and basophils count in patients with distant gastric cancer, the scores of each indexes were 20.64, 26.42, 32.83, 25.78, 38.46, 35.65, 29.06 and 18.26 scores, the total score (227.10 scores) was the incidence of the nomogram model (29.82%). The validation result showed C-index of 0.819 and 0.806 (95% CI 0.785 to 0.864 and 0.779 to 0.816), and the correction curves for both sets were fitted well to the ideal curve with AUC of 0.801 and 0.810 (95% CI 0.784 to 0.826 and 0.795 to 0.852), and the decision curve showed high net benefit value with threshold probability from 1% to 9%. Conclusions:LASSO regression model combined with white blood cell count, neutrophil percentage, NLR, lymphocyte percentage, acidophil count and basophils count is ideal to predict lymph nodes around hepatic artery metastasis in patients with distant gastric cancer.

ABSTRACT

Objective:To investigate the intervention effects and influencing factors of family management intervention on parents' disease management ability, family function of children with coronary artery lesions in Kawasaki disease.Methods:This was a quasi experimental study. Conveniently, 88 parents of children with Kawasaki disease coronary artery lesions from the Children's Hospital of Chongqing Medical University from March 2020 to June 2021 were selected for the study, and they were divided into the control group and the intervention group according to the order of the first consultation with 44 cases in each group. In the control group, conventional care and health education were used, while in the intervention group, a 6-month family management intervention was implemented on the basis of the control group. Family Management Measure (FaMM), Family Assessment Device (FAD) were used to assess the parents' disease management ability, family function before and after the intervention, respectively.Results:A total of 88 study subjects completed the pre-intervention survey in this study, and a total of 79 study subjects were surveyed when they returned to the hospital for review at the end of 6 months of intervention, including 40 in the intervention group and 39 in the control group, with a missed rate of 10.23% (9/88). There was no significant difference in the score of FAD, FaMM, Kawasaki disease knowledge questionnaire before the intervention between the two groups ( P>0.05). The scores of FAD in the intervention group was (21.58 ± 4.60) points, which was lower than that in the control group (24.62 ± 5.28) points, and the difference was statistically significant ( t=2.73, P <0.05). The scores of FaMM in the intervention group was (46.83 ± 6.02) points, which was higher than that in the control group (42.72 ± 6.09) points, and the differences was statistically significant ( t=-3.01, P <0.05). The age of the child, and whether the child was an only child were the influencing factors of the difference in disease management ability, and the difference in the family function of the parents of the child, respectively (all P<0.05). Conclusions:Family management intervention can improve the disease management ability of the parents of children with coronary artery lesion, improve family function. In the future, targeted interventions can be conducted according to different ages of children, and different family members' composition in order to obtain better intervention effects.

ABSTRACT

Intestinal flora imbalance and abnormal glucose and lipid metabolism are important risk factors and pathological mechanisms of colorectal polyps. "Spleen deficiency and dampness accumulation" is the core pathogenesis of colorectal polyps. The imbalance of intestinal flora is related to spleen deficiency, and the application of Chinese herbs for invigorating spleen is helpful to the recovery of intestinal flora balance. Abnormal glucose and lipid metabolism is related to dampness accumulation, and it is effective to treat it with bitter and spicy herbs or spleen-invigorating and dampness-eliminating herbs. The interaction between intestinal flora imbalance and abnormal glucose and lipid metabolism changes intestinal microenvironment, damages intestinal epithelial cells, causes abnormal proliferation of intestinal stem cells and leads to colorectal polyps, which is consistent with the pathogenesis of spleen deficiency and dampness accumulation in Traditional Chinese Medicine. Thus, we tried to explore the biological connotation of the pathogenesis of "spleen deficiency and dampness accumulation" of colorectal polyps from the perspective of the interaction of intestinal flora and glucose and lipid metabolism, in order to provide reference for identifying high-risk population and analyzing the therapeutic mechanism of compound prescription for invigorating spleen and removing dampness.

ABSTRACT

Regulatory T (Treg) cells are a special immunosuppressive subset of cluster of differentiation 4-positive (CD4+‍)‍-T lymphocytes and play a pivotal role in the establishment of immune homeostasis in vivo (Zhang et al., 2021). The transcription factor forkhead box protein P3 (Foxp3) is the master marker of Treg cells, which is highly expressed in Treg cells and is also essential for their suppressive function (Hori et al., 2003). In addition to Foxp3, other regulators of Treg cells have been discovered (Wu et al., 2017, 2022; Wu and Sun, 2023a, 2023b); however, a deeper understanding of the regulation of these cells is required.

ABSTRACT

Background The risks of unhealthy working mood and physical and mental health problems are high in the workers of petrochemical enterprises. Resilience is a positive psychological factor, which can provide positive ability to manage stress and job burnout, relieve tension, depression, anxiety, and other psychological discomfort. Objective To explore the moderating or mediating effect of resilience on the association between job burnout and sleep disorders in workers of petrochemical enterprises. Methods A survey with questionnaire of general information, resilience, job burnout (including exhaustion, cynicism, and professional efficacy), and sleep disorders was conducted among 1087 workers who were selected by cluster sampling from a petrochemical enterprise in Henan Province in April 2022. Mann-Whitney U test and Kruskal-Wallis H test were used to test the differences of scores among different demographic groups. Resilience, job burnout (including exhaustion, cynicism, and professional efficacy), and sleep disorder scores were analyzed by partial correlation analysis. The moderating effect of resilience was examined by linear regression analysis, and the mediating effect of resilience by Bootstrap method. Results A total of 861 questionnaires were collected, of which 857 were effective, and the effective rate was 99.5%. The M (P25, P75) of job burnout score was 1.24 (0.65, 2.22) and the incidence of job burnout was 36.4% (312/857); the scores [M (P25, P75)] of exhaustion, cynicism, and professional efficacy were 1.40 (0.80, 3.00), 1.00 (0.20, 1.60), and 5.50 (4.00, 6.00), respectively. The M (P25, P75) of resilience score was 36.00 (30.00, 41.00). The M (P25, P75) of sleep disorder score was 11.00 (7.00, 15.00). The partial correlation analysis results showed that job burnout, exhaustion, and cynicism were negatively correlated with resilience (r=−0.387, −0.248, −0.247, P<0.01), and positively correlated with sleep disorders (r=0.455, 0.445, 0.357, P<0.01); professional efficacy was positively correlated with resilience (r=0.366, P<0.01) and negatively correlated with sleep disorders (r=−0.184, P<0.01); resilience was negatively correlated with sleep disorders (r=−0.349, P<0.01). The linear regression analysis results found that job burnout, exhaustion, and cynicism elevated the risk of sleep disorders (P<0.01), resilience lowered the risk of sleep disorders (P<0.01); but the relationship between job burnout (exhaustion, cynicism, and professional efficacy) and sleep disorders was not moderated by resilience (P>0.05). The mediating effect test showed that resilience played a partial mediating role in the associations of job burnout, exhaustion, cynicism, and professional efficacy with sleep disorders, the mediating effects were 0.522 (95%CI: 0.283-0.777), 0.310 (95%CI: 0.188-0.453), 0.364 (95%CI: 0.228-0.524), −0.542 (95%CI: −0.741-−0.366) and the mediating effects accounted for 17.31%, 14.12%, 19.24%, and 64.72% of the total effects, respectively. Conclusion The relationship between job burnout and sleep disorders is partially mediated by resilience among workers in the selected petrochemical company, but no moderating effect is found.

ABSTRACT

Mucociliary clearance system is the primary innate defense mechanism of the lung. It plays a vital role in protecting airways from microbes and irritants infection. Mucociliary clearance system, which is mediated by the actions of airway and submucosal gland epithelial cells, plays a critical role in a multilayered defense system via secreting fluids, electrolytes, antimicrobial and anti-inflammatory proteins, and mucus onto airway surfaces. Changes in environment, drugs or diseases can lead to mucus overproduction and cilia dysfunction, which in turn decrease the rate of mucociliary clearance and enhance mucus gathering. The dysfunction of mucociliary clearance system often occurs in several respiratory diseases, such as primary ciliary dysfunction, cystic fibrosis, asthma and chronic obstructive pulmonary disease, which are characterized by goblet cell metaplasia, submucosal gland cell hypertrophy, mucus hypersecretion, cilia adhesion, lodging and loss, and airway obstruction.

ABSTRACT

OBJECTIVE To compare the efficacy of different enteral nutrition (EN) drugs for severe acute pancreatitis (SAP) and their gastrointestinal tolerance. METHODS A total of 118 SAP patients admitted to the Pancreatic Center of Jiangsu Provincial People’s Hospital from January 1, 2022 to June 30, 2023 were collected and divided into short-peptide EN drugs (SP) group (41 cases), dietary fiber-free intact protein EN drugs (TP-MCT) group (40 cases) and dietary fiber-containing intact protein EN drugs (TPF-DM) group (37 cases) according to the types of EN. All three groups of patients were given continuous pumps of EN drugs via nasal feeding for 24 hours, with a target energy dose of 25-30 kcal/kg. The blood nutritional indexes [albumin (ALB), total protein (TP), hemoglobin (Hb), globulin (GLB)], inflammation indexes [white blood cells (WBC), percentage of neutrophils (N%), procalcitonin (PCT), C-reactive protein (CRP), interleukin-6 (IL-6)], clinical outcomes indexes [time of stay in the intensive care unit (ICU), length of hospital stay, duration of resuming oral diet, the rate of cases without improvement, mortality rate] and the occurrence of gastrointestinal tolerance were collected from 3 groups before medication and 7 d after medication. RESULTS After treatment, ALB and TP in 3 groups were significantly higher than before treatment (P<0.05); CRP and N% of 3 groups, PCT of TP-MCT group and IL-6 of SP group were significantly lower than corresponding group before medication (P< 0.05); PCT of TP-MCT group and IL-6 of SP group were significantly lower than those of other two groups at corresponding period (P<0.05). There were no statistical significances in ALB, TP, CRP or N% among the three groups after medication, and in Hb, GLB or WBC among the three groups before and after treatment (P>0.05). There was no significant difference in clinical outcome indexes among 3 groups (P>0.05). The incidence of gastrointestinal adverse reactions in the TP-MCT group was the lowest (32.50%), and significantly lower than those in the SP group (46.34%) and TPF-DM group (48.65%) (P<0.05). CONCLUSIONS Different EN preparations can improve the nutritional status and reduce the inflammatory response in SAP patients to different extents, among which SP and TP-MCT are more effective, and TP-MCT shows the better gastrointestinal tolerance.
