ABSTRACT

Objective:With the help of SWOT(S: internal strengths, W: internal weaknesses, O: external opportunities, T: external threats)analysis, to explore the internal and external conditions of internet-based cognitive behavioral therapy applied to improve the negative emotions of patients with coronary heart disease, and to propose development strategies.Methods:SWOT analysis was used to analyze and sort out the internal strengths and internal weaknesses, external opportunities and external threats of internet-based cognitive behavioral therapy in improving the negative emotions of patients with coronary heart disease.Results:The internal strengths of internet-based cognitive behavioral therapy in improving the negative emotions of patients with coronary heart disease were significant therapeutic effect, strong operability and high cost-effectiveness. The internal weaknesses included excessive dependence on patients′ treatment enthusiasm, and a lack of psychological training among nurses. The external opportunities included demand support, technical support, and theoretical support. The external threats were the lack of large-scale empirical research and the risk of patient personal information leakage.Conclusions:In the clinical application of internet-based cognitive behavioral therapy to improve the negative emotions of patients with coronary heart disease, both strengths and weaknesses coexist, and opportunities and threats coexist. Only by taking strengths of opportunities to overcome weaknesses, improve the autonomy and enthusiasm of patients in treatment, and increase the psychological training of medical staff, can internet-based cognitive behavioral therapy be further promoted in the clinical application of improving the negative emotions of patients with coronary heart disease.

ABSTRACT

Glucocorticoid-induced ocular hypertension(GIOH)is a condition characterized by elevated intraocular pressure caused by glucocorticoids. The long-term presence of GIOH may lead to optic nerve damage and visual field defects, eventually progressing to glucocorticoid-induced glaucoma(GIG), which can potentially cause blindness. Glucocorticoids primarily exert their biological effects by mediating glucocorticoid receptor(GR), while also involving factors such as transforming growth factor(TGF)-β, Wnt, and Rho in the formation of GIOH. In-depth exploration of the pathological changes and related molecular mechanisms of the trabecular meshwork in GIOH provides an important theoretical basis for understanding the pathogenesis and treatment of GIOH. Therefore, this article provides a review of the pathological changes and molecular mechanisms of the trabecular meshwork in GIOH, aiming to provide a theoretical basis for further research on the pathological mechanisms and treatment of GIOH.

ABSTRACT

Objective:To evaluate the qualitative and quantitative diagnostic value of transvaginal contrast-enhanced ultrasonography for benign and malignant adnexal masses.Methods:Forty-nine patients with adnexal masses detected by routine ultrasound examination at Wenzhou People's Hospital from January 2021 to December 2022 were included in this study. Initially, transvaginal two-dimensional ultrasound, two-dimensional ultrasound integrated with color Doppler, and contrast-enhanced ultrasonography were used to accurately classify the masses as benign or malignant. Using postoperative pathology as the gold standard, the qualitative diagnostic accuracy of various detection methods was compared. Subsequently, the receiver operating characteristic curve analysis was performed to assess the quantitative diagnostic accuracy of transvaginal contrast-enhanced ultrasonography-related parameters in distinguishing between benign and malignant adnexal masses.Results:Among the 49 patients, 10 were diagnosed with malignant tumors. The diagnostic accuracy of contrast-enhanced ultrasonography was 93.88% (46/49), with a sensitivity of 90.00% (9/10), a specificity of 94.87% (37/39), a positive predictive value of 81.82% (9/11), and a negative predictive value of 97.37% (37/38). The results of the diagnostic difference assessment (McNemar test) revealed that there was no significant difference between two-dimensional ultrasound ( χ2 = 0.37, P = 0.546), two-dimensional ultrasound combined with color Doppler ( χ2 = 0.17, P = 0.683), and contrast-enhanced ultrasonography ( χ2 = 0.00, P = 1.000), and the gold standard test results. The consistency assessment (Kappa test) revealed that the diagnostic results of contrast-enhanced ultrasonography exhibited the highest concordance with the gold standard, with a Kappa value of 0.82 ( P < 0.001). Furthermore, the receiver operating characteristic curve analysis indicated that the initial increase time, peak intensity, and mean transit time in contrast-enhanced ultrasonography demonstrated high quantitative diagnostic accuracy. The areas under the curve were 0.83, 0.82, and 0.84, respectively, and the diagnostic cutoff values were 17.30 s, 21.65 dB, and 92.60 seconds, respectively. Conclusion:Contrast-enhanced ultrasonography exhibits diagnostic value in the differential diagnosis of benign and malignant adnexal masses, both qualitatively and quantitatively. This method can provide valuable insights for further treatment.

ABSTRACT

Objective:To analyze the clinical features of MDA5 antibody positive dermatomyositis (MDA5-DM) and to provide evidence for early diagnosis and treatment.Methods:From March 2019 to June 2021, 272 patients with anti-MDA5-DM from the Nanjing Medical University myositis-associated interstitial lung disease cohort were enrolled, with 76 patients with anti-synthetase syndrome (ASS) as the control group. The clinical characteristics and the occurrence of interstitial lung disease were analyzed. T-test was used for normally distributed and variance-homogeneous independent samples, Mann-Whitney U test for non-normally distributed data, and chi-square test or Fisher′s exact test for dichotomous variables. Results:Among the 272 anti-MDA5-DM patients, 88.6% (241/272) developed interstitial lung disease (ILD), and 33.8% (92/272) developed rapidly progressive ILD (RP-ILD). The six-month all-cause mortality rate of anti-MDA5-DM patients was 16.9% (46/272), and it was as high as 47.8% (44/92) for those with RP-ILD. Compared with ASS patients, anti-MDA5-DM patients had a significantly higher proportion of males, arthritis, Gottron's sign, heliotrope rash, V-sign, periungual erythema, and skin ulcers ( P<0.05). The levels of ALT, AST, and ferritin were significantly increased ( P<0.05). Compared with non-RP-ILD patients, RP-ILD patients had a significantly higher proportion of males [35.9%(33/92) vs. 23.3%(42/180), χ2=4.79, P=0.029], higher levels of LDH [387 (276, 547) U/L vs. 310 (245, 400) U/L, Z=-3.67, P<0.001], ESR [45.5 (29.25, 63.25) mm/1 h vs. 31.2 (20, 51) mm/1 h, Z=-3.71, P<0.001], CRP [10.9 (4.1, 25.2) mg/L vs. 4.54 (2.58, 9.08) mg/L, Z=-4.97, P<0.001], ferritin [1 340 (650, 2 000) ng/ml vs. 556 (203, 1 186) ng/ml, Z=-4.40, P<0.001], and a higher proportion of anti-Ro52 antibody and anti-MDA5 antibody co-positivity [87.0%(80/92) vs. 52.2%(94/180), χ2=31.87, P<0.001]. Conclusion:Anti-MDA5-DM patients are prone to develop RP-ILD and have poor prognosis.

ABSTRACT

Objective:To evaluate the effect of sitagliptin on the expression of airway mucin 5AC (MUC5AC) in mice with endotoxin-induced lung injury.Methods:Thirty-six healthy male SPF C57BL/6 mice, aged 6-8 weeks, weighing 20-25 g, were divided into 3 groups ( n=12 each) using a random number table method: control group (group C), endotoxin-induced lung injury group (group L), and endotoxin-induced lung injury+ sitagliptin group (group S). Lipopolysaccharide (LPS) 3 mg/kg was intratracheally infused to prepare endotoxin-induced lung injury model in L and S groups, while the equal volume of normal saline was given instead in group C. Sitagliptin 100 mg/kg was intraperitoneally injected at 1 h before LPS infusion in group S, and normal saline was intraperitoneally injected at 1 h before endotracheal infusion in C and L groups. The arterial blood samples from femoral artery were taken at 24 h of LPS or normal saline infusion for measurement of PaO 2 and glucose levels.The mice were then sacrificed, and broncho-alveolar lavage fluid (BALF) and lung tissues were collected for determination of the concentrations of interleukin-6 (IL-6), interleukin-1beta (IL-1β), and tumor necrosis factor-alpha (TNF-α)in serum and BALF (by enzyme-linked immunosorbent assay), wet/dry weight ratio (W/D ratio), expression of MUC5AC (by immunohistochemistry and immunohistochemical comprehensive score), and expression of MUC5AC mRNA in lung tissues (by quantitative real-time polymerase chain reaction) and for examination of the pathological changes of lung tissues (using haematoxylin and eosin staining) which were scored. Results:Compared with group C, PaO 2 was significantly decreased, the glucose levels, W/D ratio and lung injury score were increased, the concentrations of IL-6, IL-1β and TNF-α in serum and BALF were increased, and the expression of MUC5AC mRNA in lung tissues was up-regulated in L and S groups( P<0.05). Compared with group L, PaO 2 was significantly increased, the glucose levels, W/D ratio and lung injury score were decreased, the concentrations of IL-6, IL-1β and TNF-α in serum and BALF were decreased, and the expression of MUC5AC mRNA in lung tissues was down-regulated in group S( P<0.05). Conclusions:The mechanism by which sitagliptin alleviates endotoxin-induced lung injury is related to down-regulation of MUC5AC expression in mice.

ABSTRACT

ObjectiveTo investigate the association between ZJU index and the onset of nonalcoholic fatty liver disease (NAFLD) in the Uygur population and the value of ZJU index in predicting the risk of NAFLD. MethodsThe Uighur community of The 51st Regiment of The Third Division of Xinjiang Kashgar Corps was selected as the investigation site, and the Uygur residents who lived in this area and had an age of >18 years were selected as subjects. Follow-up studies were conducted in 2019, 2020, and 2021, and the investigation of outcomes was completed in June to August of 2021. Finally 10 597 subjects were enrolled for analysis. The Kruskal-Wallis H test was used for comparison of continuous variables between groups, and the chi-square test was used for comparison of categorical variables between groups. The subjects were divided into Q1-Q4 groups according to the level of ZJU index. The Kaplan-Meier curve was used to predict the incidence rate of NAFLD, and the Cox regression model was used to analyze the association between ZJU index and the risk of NAFLD; the area under the ROC curve (AUC) was used to evaluate the value of ZJU index in predicting the risk of NAFLD. ResultsDuring the median follow-up time of 4.92 years, the incidence rate of NAFLD was 9.4% (992/10 597) among the study population. After adjustment for multiple factors, there was a significant increase in the risk of NAFLD with the increase in ZJU index, with a hazard ratio of 2.55 (95% confidence interval [CI]: 1.60‍ — ‍4.06), 7.32 (95%CI: 4.78‍ — ‍11.20), and 21.74 (95%CI: 14.32‍ — ‍33.00), respectively (all Ptrend<0.001). The ROC curve showed that ZJU index had a higher value in predicting NAFLD (AUC=0.816), and the male subgroup had a significantly higher predictive accuracy of ZJU index than the female subgroup (AUC: 0.829 vs 0.809). ConclusionZJU index is a predictive factor for the onset of NAFLD in the Uygur population in rural areas of Xinjiang and has a good value in predicting the risk of NAFLD.

ABSTRACT

After systematically reviewing the syndrome distribution, evolution, diagnostic criteria, effectiveness evaluation and genomics study on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in the past decade, we found that there are problems such as inconsistency in the nomenclature of syndrome, lack of quantitative diagnostic tools for syndrome, less developed evaluation tools for syndrome efficacy, and singularity of genomics technique. Based on this, it was proposed that we should pay attention to the standardisation of syndrome naming, strengthen the research on quantitative diagnostic methods, establish standardised and quantitative diagnostic tools, further improve the existing assessment tools of syndrome effectiveness, and integrate the existing genomics techniques to conduct research, so as to support the further research on AECOPD syndromes.

ABSTRACT

Objective To explore the nutritional efficacy of compound protein powder formulations from different sources. Methods Three groups of compound protein powder formulations were obtained through scientific blending using soy protein, whey protein and yeast protein as raw materials. The effects of the compound protein powders on nitrogen metabolism, serum biochemical indicators, and pathological changes of liver tissue and epididymal fat in rats were evaluated. Results Compared with the control (casein), the net protein utilization, biological evaluation, and protein efficacy ratio of the compound protein powders in rats were significantly improved, and the changes in these indicators in the formula with the highest whey protein content were most significant among all three formulas. The compound protein powders effectively increased the levels of albumin and globulin, while decreased the content of total cholesterol, indicating beneficial effects on improving immunity and controlling lipid metabolism, with the formula group 2 being the most effective among all three groups. The pathological examination showed that the three groups of protein powder did not have adverse effects on liver tissue and epididymal fat. Conclusion The present study demonstrates that the compound protein powder formulation has nutritional value, which suggests a potential of the application of the compound protein powder formulation in the elderly, and people with special nutritional needs, such as sports people.

ABSTRACT

OBJECTIVE To establish HPLC fingerprint of Portulaca oleracea, establish quantitative analysis of multi- components by single-marker (QAMS) method for the content determination of caffeic acid, ferulic acid, genistin and quercetin, and provide reference for quality control of the medicine. METHODS The determination was performed on Eclipse XDB-C18 column with mobile phase consisted of methanol-0.2% phosphoric acid solution (gradient elution) at the flow rate of 1.0 mL/min. The column temperature was 25 °C, and detection wavelength was set at 360 nm. The sample size was 10 μL. HPLC fingerprint of P. oleracea was established according to the above chromatographic conditions. Cluster analysis (CA) and principal component analysis (PCA) were performed for 15 batches of specimens. Using caffeic acid as internal standard, relative correction factors of other three components were calculated by QAMS, and then the component content was calculated on the basis of relative correction factors, which was compared with the external standard method. RESULTS HPLC fingerprints of 15 batches of P. oleracea were calibrated with a total of 17 common peaks, and 4 components (caffeic acid, ferulic acid, genistin, quercetin) were identified; the similarities of 15 batches of samples were greater than 0.890. The results of CA showed that S1-S10 were clustered into one category, and S11-S15 were clustered into one category. The results of PCA revealed that the accumulative contribution rate of the two main components was 92.502%, and the classification results were basically consistent with CA. The linear range of caffeic acid, ferulic acid, genistin and quercetin were 0.003 1-0.157 1, 0.003 6-0.181 7, 0.008 5-0.425 6,0.000 4-0.021 8 mg/mL (R2≥0.999 7); the results of precision, repeatability, stability (24 h) and recovery tests all complied with the requirements of Chinese Pharmacopoeia. The relative correction factors of ferulic acid, genistin and quercetin calculated by QAMS were 1.534, 5.302 and 0.174; there was no significant difference in the contents of components measured between this method and the external standard method. CONCLUSIONS The established HPLC fingerprint combined with QAMS can be used for the quality control of multiple index components in P. oleracea. The origin has a certain influence on the quality of P. oleracea, and the quality of P. oleracea produced in Sichuan is better than that produced in Anhui and Hebei.

ABSTRACT

Idiopathic pulmonary fibrosis (IPF) is a chronic progressive fibrotic interstitial pneumonia with unknown causes. The incidence rate increases year by year and the prognosis is poor without cure. Recently, phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB/AKT) signaling pathway can be considered as a master regulator for IPF. The contribution of the PI3K/AKT in fibrotic processes is increasingly prominent, with PI3K/AKT inhibitors currently under clinical evaluation in IPF. Therefore, PI3K/AKT represents a critical signaling node during fibrogenesis with potential implications for the development of novel anti-fibrotic strategies. This review epitomizes the progress that is being made in understanding the complex interpretation of the cause of IPF, and demonstrates that PI3K/AKT can directly participate to the greatest extent in the formation of IPF or cooperate with other pathways to promote the development of fibrosis. We further summarize promising PI3K/AKT inhibitors with IPF treatment benefits, including inhibitors in clinical trials and pre-clinical studies and natural products, and discuss how these inhibitors mitigate fibrotic progression to explore possible potential agents, which will help to develop effective treatment strategies for IPF in the near future.

ABSTRACT

Objective:To explore the influence of flipped classroom combined with case-based learning (CBL) teaching mode on teaching effect of X-ray cephalometric analysis in orthodontic experimental class.Methods:In the study, 70 undergraduates majoring in stomatology were selected as research objects and randomized into teaching reform group and traditional group in average. Flipped classroom combined with CBL teaching mode was adopted in teaching reform group, while traditional group adopted traditional teaching mode. Questionnaire was used to investigate the students' evaluation on the two teaching modes, and the accuracy of the measurement of X-ray cephalometrics of the two groups was compared and analyzed respectively. GraphPad Prism 7.03 software was used to perform t test and chi-square test. Results:Teaching reform group believed that this kind of teaching mode could improve the ability of self-study, communication coordination ability, independent problem solving ability, and logic and language expression ability, deepen the understanding of the project connotation, and apply the X-ray cephalometrics to the actual clinical case analysis and diagnosis. Compared with the traditional group, there were significant differences ( P<0.05). In the accuracy evaluation of measurement values, the absolute values of 70% measurement items in teaching reform group were higher than those in the traditional group, but the difference was not statistically significant ( P>0.05). Only in bone type Ⅲ malocclusion, the absolute values of Y-axis angle and FMA were lower than those of the traditional group, and the difference was statistically significant ( P<0.05). Conclusion:Flipped classroom combined with CBL teaching mode can help students improve self-study ability, communication cooperation ability and the ability of solving problem independently and clinical application. However, the accuracy evaluation of measurement values in teaching reform group were lower than that of the traditional group, indicating that this teaching method in the experimental teaching of X-ray cephalometric analysis needs to be further improved.
