Methods: After screening the dataset provided in the published literature, this study included 495 CHMs and their 8 075 compounds. Three molecular descriptors were used to represent the compounds: the molecular access system (MACCS), extended connectivity fingerprint (ECFP), and two-dimensional (2D) molecular descriptors computed by the RDKit open-source toolkit (RDKit_2D). A homogeneous graph with CHMs as nodes was constructed and a classification model for the cold and hot medicinal properties of CHMs was developed based on a GCN using the molecular descriptor information of the compounds as node features. Finally, using accuracy and F1 score to evaluate model performance, the GCN model was experimentally compared with the traditional machine learning approaches, including decision tree (DT), random forest (RF), k-nearest neighbor (KNN), Naïve Bayes classifier (NBC), and support vector machine (SVM). MACCS, ECFP, and RDKit_2D molecular descriptors were also adopted as features for comparison. Results: The experimental results show that the GCN achieved better performance than the traditional machine learning approach when using MACCS as features, with the accuracy and F1 score reaching 0.836 4 and 0.845 3, respectively. The accuracy and F1 score have increased by 0.8690 and 0.8120, respectively, compared with the lowest performing feature combination OMER (only the combination of MACCS, ECFP, and RDKit_2D). The accuracy and F1 score of DT, RF, KNN, NBC, and SVM are 0.505 1 and 0.501 8, 0.616 2 and 0.601 5, 0.676 8 and 0.624 3, 0.616 2 and 0.607 1, 0.636 4 and 0.622 5, respectively. Conclusion In this study, by introducing molecular descriptors as features, it is verified that molecular descriptors and fingerprints play a key role in classifying the cold and hot medicinal properties of CHMs. Meanwhile, excellent classification performance was achieved using the GCN model, providing an important algorithmic basis for the in-depth study of the “structure-property” relationship of CHMs.

Objective:To investigate the mechanism of polygonatum and astragalus compound(PA)in inhibiting the progression of lung adenocarcinoma. Methods:CCK-8 assay was used to assess the inhibitory rate of proliferation in A549 and H1299 cells treated with PA at different concentrations and to calculate the half maximal inhibitory concentration(IC50).C57BL/6 mice(KRASG12D/+;TP53flox/flox)were treated with adenovirus carrying Cre enzyme via nasal inhalation to establish a mouse model of primary lung adenocarcinoma.The model mice were fed with PA-containing diet to directly observe the effect of PA on the lung adenocarcinoma tissue.Immunohistochemical staining was used to examine the pathological status of the lung tissue.Bioinformatics analysis indicated that PA affects the progression of lung adenocarcinoma through the apelin-peroxisome proliferator-activated receptor gamma coactivator 1-alpha(PGC1α)-mitochondrial brown fat uncoupling protein 1(UCP1).Real-time quantitative PCR and Western blotting analysis were used to study the effect of PA on the mRNA and protein expression levels of apelin-PGC1α-UCP1 signaling pathway related genes.An ATP detection kit and flow cytometry were used to evaluate the effect of PA on the ATP and mitochondrial ROS production,respectively,in A549 and H1299 cells.siUCP1 was used to silent the expression of UCP1 while Z160 was used to induce UCP1 overexpression in A549 and H1299 cells,and the changes in ATP and mitochondrial ROS production were examined to further investigate whether PA acts on apelin-PGC1α-UCP1 signaling pathway to affect the progression of lung adenocarcinoma. Results:PA could obviously inhibit the proliferation of A549 and H1299 cells with the IC50 values of 10.66 mg/mL for A549 cells and 9.66 mg/mL for H1299 cells.In the mouse primary lung adenocarcinoma model,PA could effectively inhibit the growth of tumor,downregulate apelin-PGC1α-UCP1 signaling pathway and inhibit the expression of lung adenocarcinoma-promoting gene UCP1.In A549 and H1299 cells,PA could significantly inhibit the expression of apelin,PGC1α and UCP1(P＜0.05),promote the production of ATP(P＜0.000 1)and ROS,restore mitochondrial oxidative phosphorylation,and inhibit aerobic glycolysis(P＜0.01).UCP1 silencing could increase the production of ATP(P＜0.01)and mitochondrial ROS and decrease the expression of key glycolysis enzymes hexokinase 2(HK2)and pyruvate kinase isozyme type M2(PKM2)(P＜0.05).Increasing the expression of UCP1 could reduce the ATP production(P＜0.01)and mitochondrial ROS generation in cells while increase the expression of HK2 and PKM2(P＜0.05).Treating cells with PA and Z160 simultaneously(PA+Z160)could reverse the inhibitory effect of PA on the ATP production and glycolysis of tumor cells(P＜0.05). Conclusion:PA can downregulate the apelin-PGC1α-UCP1 signaling pathway,inhibit mitochondrial uncoupling,restore mitochondrial oxidative phosphorylation,inhibit aerobic glycolysis,reverse the Warburg effect,and thus inhibit lung adenocarcinoma progression.

Objective:To explore the association between sleep duration, sleep quality and the prevalence of hypertension in the elderly aged 65 years and above.Methods:This study was conducted among the elderly in communities in Yiwu, China from April to July, 2019, and participants were recruited through physical examination in the hospital. Face-to-face interview was performed to obtain basic information. Sleep duration and sleep quality were evaluated by Pittsburgh Sleep Quality Index (PSQI). Associations between sleep duration, sleep quality and hypertension were evaluated by multivariate logistic regression analysis.Results:A total of 3 169 elderly persons, aged ≥65 years old, were included in the study. The overall prevalence of hypertension was 50.8%. The elderly with very poor sleep quality and short sleep duration accounted for 22.4% and 28.5%, respectively. After adjusting for demographic characteristics, socioeconomic status, lifestyle and health status, the OR of hypertension for the elderly with very poor sleep quality was 1.42 (95% CI: 1.12-1.80) compared with those with very good sleep quality. Compared with the elderly with sleep duration of 6-7 h a night, the OR of hypertension for those with sleep duration <6 h was 1.37 (95% CI: 1.15-1.65). As the sleep quality decreased, the risk for hypertension increased. An U-shaped association was found between sleep duration and risk of hypertension. Subgroup analyses showed that this association existed in both men and women, but only significant in the elderly aged <75 years. Conclusion:Poor sleep quality and short sleep duration were associated with risk for hypertension in the elderly.

Objective:To explore the influencing factors of job burnout of medical staff and provide reference for the formulation of intervention measures.Methods:From November to December, 2018, a questionnaire survey was conducted among medical staff in a general hospital by using the research design of the current situation survey. A total of 1193 questionnaires were distributed and 939 questionnaires were returned, with a recovery rate of 78.7%, including 891 valid questionnaires and an effective recovery rate of 94.9%. Social support rating scale (SSRs) was used to evaluate social support, and Maslach Burnout Scale (MBI-GS) was used to evaluate job burnout. Single factor analysis was performed by chi square test and Fisher exact probability method. To explore the influencing factors of job burnout by using disordered multi classification logistic.Results:The average age was (27.47 ± 4.22) years old, female accounted for 71.5% (637/891) . The total physical examination rate of job burnout was 46.6%. The scores of emotional exhaustion, cynicism and decreased sense of achievement were (10.10±3.75) , (6.14±3.43) , (17.91±4.13) respectively. Multiple logistic regression analysis showed that, compared with the non detected job burnout, the young, working for 1-3 years, average sleep ≤6 hours, and poor social support were more likely to have mild job burnout ( OR=0.91, 0.40, 2.25, 2.38, P<0.05) ; female, high night shift frequency in the past year, average sleep ≤6 h. Those with poor social support were more likely to have moderate to severe job burnout ( OR=1.59, 2.94, 4.01, 2.40, 3.66, P<0.05) . Conclusion:Corresponding measures should be taken to reduce job burnout and improve work efficiency.

OBJECTIVETo assess the accuracy of quantitative fluorescence PCR(QF-PCR) for the detection of fetal chromosomal aneuploidies and its values for prenatal diagnosis.

METHODSQF-PCR and chromosomal karyotyping were used to analyze 6066 amniotic fluid samples derived from 6034 pregnant women.

RESULTSBoth QF-PCR and karyotyping analysis have detected 135 cases of fetal aneuploidies involving chromosomes 21, 18, 13, X, and Y. The QF-PCR assay was also successful in 67 cases for which amniotic fluid culture has failed. Furthermore, it has identified maternal cell contamination in 7 cases. By determining the consistency of short tandem repeat (STR) sites, the QF-PCR assay has identified 22 dizygotic twins among 32 twins with double chorions and double amniotic sacs. In 12 cases, it has signaled numerical chromosomal aberration by critical or partial abnormal values for the fluorescence peak area ratio, which were verified by karyotyping analysis as mosaicisms of chromosome aneuploidies.

CONCLUSIONThe QF-PCR can provide an useful supplement for chromosomal karyotyping and has an important role in rapid prenatal diagnosis.

OBJECTIVE: To explore the clinical characters and treatment on solitary sphenoidal sinus disease thus improve the initial diagnosis accuracy and curative rate together with avoiding severe complications. METHOD: Forty-six cases were included in the study. The clinical manifestations, medical imaging characteristics and type of pathology and surgical treatment efficacy were analyzed retrospectively. RESULT: The main symptoms were headache and visual lesion. Medical image showed pace occupying lesion and partial destruction of bone. Pathological exams showed 8 cases with sphenoiditis, 19 cases with fungal infection, 10 cases with cysts and 9 cases with polyposis. All the patients underwent open sphenoidal surgery with nasal endoscope. After a follow-up of over 6 months, most of the patients' symptoms had been obviously relieved. And the entrance to sphenoid was patent with smooth sinus wall and no secretion in sinus cavity. CONCLUSION There is no specificity with solitary sphenoidal sinus disease. Pre-operation diagnosis rate can be improved with the help of nasal endoscope and CT or MRI. Nasal sinus surgery with nasal endoscope may be the first choice for treatment.
