Objective:To evaluate the predictive value of whole blood cell derived inflammatory marker (including systemic immunoinflammatory index (SII), systemic inflammatory response index (SIRI), neutrophil count/lymphocyte count (NLR), platelet count/lymphocyte count (PLR), and monocyte count/lymphocyte count (MLR)) and in combination with N-terminal pro-B-type natriuretic peptide (NT-proBNP) on the prognosis of patients with chronic heart failure.Methods:This study was a retrospective cohort study. Patients with chronic heart failure hospitalized in the Department of Cardiovascular Medicine, Nanfang Hospital, Southern Medical University from January 2019 to August 2022 were enrolled. Patients were followed up and were divided into survival group and death group according to the follow-up results. Clinical characteristics of the two groups were compared. Receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value of each whole blood cell derived inflammatory marker for predicting all-cause death in patients with chronic heart failure. Kaplan-Meier survival curve was drawn, and log-rank test was used to compare the difference in survival of chronic heart failure patients with different levels of whole blood cell derived inflammatory markers. Univariate and multivariate Cox proportional hazards models were used to analyze the effects of whole blood cell derived inflammatory markers and NT-proBNP on the all-cause death of patients with chronic heart failure. ROC curve was used to analyze the predictive value of whole blood cell derived inflammatory markers combined with NT-proBNP on the prognosis of patients with chronic heart failure.Results:A total of 324 patients with heart failure aged (64.76±13.78) years were enrolled, with 212 males (65.43%). 297 patients (91.67%) completed follow-up, 27 patients (8.33%) were lost to follow-up. The follow-up time was 24.0 (18.0, 41.8) months. There were 258 patients in the survival group and 66 patients in the death group. The optimal cut-off values of SII, SIRI, NLR, PLR and MLR determined by ROC curve were 739.83, 1.65, 3.14, 151.95 and 0.37, respectively. Kaplan-Meier survival curve analysis showed that patients with chronic heart failure with high levels of SII (≥739.83), SIRI (≥1.65), NLR (≥3.14), PLR (≥151.95) and MLR (≥0.37) had higher incidence of all-cause death than patients with low levels of inflammatory markers (all P<0.001). Multivariate Cox proportional hazard regression analysis showed that age ( HR=1.04, 95% CI 1.01-1.06, P=0.002), NT-proBNP ( HR=2.93, 95% CI 1.64-5.23, P<0.001), SII≥739.83 ( HR=3.27, 95% CI 1.18-9.02, P=0.022) and PLR≥151.95 ( HR=2.67, 95% CI 1.02-6.96, P=0.045) were independent predictors of all-cause death in patients with chronic heart failure. ROC curve analysis showed that the predictive value of SII and PLR combined with NT-proBNP ( AUC=0.850) for the prognosis of patients with chronic heart failure was better than that of SII ( AUC=0.779)、PLR ( AUC=0.782)、NT-proBNP ( AUC=0.727) and CRP ( AUC=0.668) alone (all P<0.001). Conclusions:Whole blood cell derived inflammatory markers——SII, PLR, and NT-pro BNP were independently associated with all-cause death in patients with chronic heart failure. SII and PLR can independently predict the prognosis of patients with chronic heart failure, combination of SII and PLR with NT-pro BNP has better predictive value for the prognosis of patients with chronic heart failure.

Objective To analyze the effects of GATA binding protein 3(GATA3)mediated mini RNA-21(miR-21)/phosphatase and tensin homologue(PTEN)axis missing from human chromosome Chromosome 10 on the proliferation and invasion of endometrial cancer cells.Methods HEC-1-A cells were transfected and divided into control group,GATA3 empty plasmid group,GATA3 overexpression plasmid group,GATA3 siRNA negative control group,and GATA3 siRNA group.Detect the expression levels of GATA3,miR-21,PTEN,proliferation,apoptosis rate,migration,and invasion in each group of cells.Results Compared with the hEEC group,the expression levels of GATA3 and miR-21 in cells of the HEC-1-A group,HEC-1-B group,and Ishikawa group increased,while the expression levels of PTEN decreased(P<0.05).Compared with the GATA3 empty plasmid group,the GATA3 overexpression plasmid group showed an increase in GATA3,miR-21 mRNA expression,pro-liferation rate,migration distance,number of invading cells,and Vimentin levels,while the PTEN mRNA expression,apoptosis rate,Caspase-9,Bax,and E-cadherin levels decreased(P<0.05);Compared with the GATA3 siRNA negative control group,the GATA3,miR-21 mRNA expression,proliferation rate,migration distance,number of invading cells,and Vimentin level decreased,while the PTEN mRNA expression,apoptosis rate,Caspase-9,Bax,and E-cadherin levels increased(P<0.05).Conclusion Downregulation of GATA3 expression can regulate the miR-21/PTEN axis,slow down the proliferation of HEC-1-A cells,and promote apoptosis of HEC-1-A cells.

Objective To explore the expression levels and clinical significance of basement membrane genes in endometrial carcinoma and the prognostic value of a prediction model.Methods The mRNA expression matrix and clinical data for endometrial carcinoma were obtained from The Cancer Genome Atlas(TCGA)database,and basement membrane genes were obtained from a previous study.Prognostic genes were screened using univariate and multivariate Cox regression analyses based on differentially expressed genes(DEGs).A prognostic model was constructed,and the relationship of these genes with clinical factors was analyzed.The biological functions and pathways of the DEGs were assessed using functional enrichment analyses.The mRNA expression of prognostic genes was verified using real-time polymerase chain reaction(PCR).Results The prognostic model composed of ACHE,COL12A1,and CD44was significantly associated with clinical factors.Real-time PCR results showed that the expression levels of ACHEand COL12A1mRNA differed signifi-cantly between normal endometrial cells and endometrial carcinoma cells(P<0.05).Conclusion The constructed model based on three basement membrane genes can accurately predict the prognosis of patients with endometrial carcinoma and provide potential targets for clinical treatment.

Objective:To investigate the prognostic value of serum levels of miR-134 and miR-146b in elderly patients with acute ischemic stroke(AIS).Methods:A total of 162 elderly patients with AIS admitted to the Third People's Hospital of Haikou from January 2017 to October 2019 were enrolled.According to modified Rankin Scale(mRS)scores, they were divided into the good prognosis group(n=98, mRS score≤2)and the poor prognosis group(n=64, mRS score>2). Based on the National Institutes of Health Stroke Scale(NIHSS), patients were divide into the mild group(n=46, NIHSS score<5), moderate group(n=75, 5≤NIHSS score≤20), and severe group(n=41, NIHSS score>20). Real-time fluorescence quantitative PCR was used to detect serum levels of miR-134 and miR-146b in each group.Multivariate logistic regression was used to analyze risk factors for poor prognosis in elderly patients with AIS.The receiver operating characteristic(ROC)curve was used to analyze the value of serum miR-134 and miR-146b levels in predicting poor prognosis of elderly patients with AIS.Pearson correlation was used to analyze the correlations of serum levels of miR-134 and miR-146b with NIHSS and mRS scores in elderly patients with AIS.Results:Serum levels of miR-134(3.26±1.13 vs.0.85±0.38)and miR-146b(2.27±0.93 vs.0.56±0.21)were higher in the AIS group than in the control group( t=14.360 and 12.527, P<0.01). Serum levels of miR-134(4.35±1.46 vs.2.28±0.85)and miR-146b(3.07±1.04 vs.1.51±0.66)were higher in the poor prognosis group than in the good prognosis group( t=13.520 and 11.242, P<0.01). Serum levels of miR-134 and miR-146b in the severe group were higher than in the moderate and mild groups( t=10.815 and 9.462, P<0.01), and they were also higher in the moderate group than in the mild group( t=13.627, 11.611, P<0.01). Multivariate Logistic regression analysis showed that serum miR-134( OR=2.470, 95% CI: 1.603-4.927)and miR-146b( OR=1.914, 95% CI: 1.350-3.406)were risk factors for poor prognosis in elderly AIS patients( P<0.05). The ROC curve analysis showed that the optimal cut-off values of serum miR-134 and miR-146b to predict poor prognosis in elderly AIS patients were 3.84 and 2.68, respectively.The area under the ROC curve(AUC)of combined serum miR-134 and miR-146b(0.926, 95% CI: 0.865-0.987)for the prediction of poor prognosis was higher than that of either marker alone, with a sensitivity and specificity of 92.4% and 86.2%, respectively.The correlation analysis showed that serum levels of miR-134 and miR-146b were positively correlated with NIHSS and mRS scores in elderly AIS patients( r=0.806, 0.871, 0.785 and 0.842, all P<0.01). Conclusions:Increased serum miR-134 and miR-146b levels are correlated with the severity of neurological impairment and prognosis in elderly patients with AIS.Serum miR-134 and miR-146b levels together have a high value in predicting poor prognosis in elderly AIS patients.

Objective:To screen and evaluate sunscreen cosmetics for sensitive facial skin.Methods:From June to August in 2019, 40 subjects with positive lactic acid sting test were recruited from the staff of Chongqing Traditional Chinese Medicine Hospital, and subjected to human skin closed patch testing with 4 kinds of sunscreen cosmetics for sensitive skin (marked as products Ⅰ, Ⅱ, Ⅲ, Ⅳ respectively) separately. Then, the 40 subjects were equally divided into 2 groups to apply 2 sunscreen products with relatively higher safety (according to the above closed patch testing results) on the face respectively. Erythema, edema and desquamation were evaluated at baseline, 2 and 4 weeks after application of the 2 products, and non-invasive measurement methods were used to detect transepidermal water loss (TEWL) , stratum corneum hydration, skin melanin content and skin sebum content. In additon, the 2 products were applied on the back of the subjects separately, and an ultraviolet solar simulator was used to determine the sun protection factor (SPF, n = 12) and protection factor of UVA (PFA, n = 11) . Measurement data were compared using paired t test and one-way analysis of variance, and nonparametric data were compared using Wilcoxon signed rank test. Results:Patch testing showed that only 1 subject developed a grade 1 reaction to the sunscreen product Ⅲ, no subjects showed positive reactions to the product Ⅳ, and the safety of products Ⅲ and Ⅳ was higher than that of the other 2 products. Subjective safety evaluation revealed that the degree of erythema after 4-week application of products Ⅲ and Ⅳ was significantly lower than that before application (Wilcoxon signed rank test, Z = 4.73, 4.82 respectively, both P < 0.05) . Objective efficacy evaluation revealed that the TEWL, stratum corneum hydration and skin melanin content significantly differed among different time points (baseline, after 2- and 4-week application of products Ⅲ and Ⅳ, all P < 0.05); after 4-week application of products Ⅲ and Ⅳ, the TEWL (30.05 ± 1.47, 30.37 ± 1.28 respectively) and skin melanin content (112.58 ± 7.34, 103.47 ± 5.48 respectively) were significantly lower than those before application (all P < 0.05) , and the stratum corneum hydration (62.35 ± 2.67, 63.72 ± 2.54 respectively) was significantly higher than that before application (both P < 0.05) . At week 4, the skin melanin content was significantly lower in the product Ⅳ group (103.47 ± 5.48) than in the product Ⅲ group (112.58 ± 7.34, t = 8.45, P < 0.05) . The SPF and PFA values of the product Ⅳ (51.8 ± 2.9, 10.1 ± 1.2 respectively) were both significantly higher than those of the product Ⅲ (31.5 ± 2.6, 7.4 ± 0.7, t = 15.34, 24.66, respectively, both P < 0.05) . Conclusion:Comprehensive application of closed patch testing, long-term application test and sun protection index determination can be used to screen and evaluate the safety and efficacy of sunscreen cosmetics for sensitive facial skin.

Objective:To analyze clinical characteristics of cosmetics-related adverse reactions and main allergenic components of cosmetics, to provide guidance for cosmetics-related adverse reaction monitoring, and to provide an objective basis for risk assessment.Methods:A total of 512 patients with suspected cosmetic adverse reactions were collected from the outpatient clinic of Chongqing Traditional Chinese Medicine Hospital from March 2018 to October 2019, including 14 males and 498 females. A uniform cosmetic adverse reaction report card was filled in, and medical history of patients and related information about the used cosmetics were recorded; 103 patients (3 males and 100 females) were subjected to patch test with their own cosmetics or cosmetic ingredients, and 48- and 72-hour patch test results were combined for comprehensive determination and analysis.Results:Among the 512 cases of suspected cosmetic adverse reactions, contact dermatitis (495 cases, 96.7%) was the most common manifestation. Cosmetic adverse reactions mainly manifested as erythema (501 cases, 97.9%), papules (313, 61.1%), edema (249, 48.6%), and scaling (166, 32.4%) ; main symptoms included itching (480, 93.8%), burning sensation (359, 70.1%), and tense sensation (297, 58.0%). Patch test with cosmetic ingredients showed positive reactions in 71 of 103 cases, and thimerosal was the allergen mostly liable to cause adverse reactions (31 cases, 30.1%), followed by sodium dodecyl sulfate (29 cases, 28.2%), Peru balsam (17 cases, 16.5%), bronopol (12 cases, 11.7%) and triethanoamine (10 cases, 9.7%). The cosmetic allergens were divided into 14 categories, and the top 4 categories with high positive patch test rates were emulsifiers (54 cases, 45.8%), preservatives (47 cases, 39.8%), fragrances (17 cases, 14.4%) and surfactants (10 cases, 8.5%). Positive patch test reactions were observed in 2 males and 69 females, and there was no significant difference in the positive rate between males and females (2/3 vs. 69/100, χ2 = 0.01, P > 0.05) ; there was also no significant difference in the positive rate among the groups aged 18 - 29 years (34%), 30 - 49 years (34%) and 50 - 70 years (32.4%; χ2 = 0.693, P > 0.05) . Conclusions:Contact dermatitis is the most common adverse reaction to cosmetics. Among the diverse allergenic components of cosmetics, thimerosal is the allergen that is mostly liable to cause adverse reactions, followed by sodium dodecyl sulfate, Peru balsam, bronopol and triethanoamine.

OBJECTIVE: To investigate the prevalence and relevant influencing factors of gynecological diseases of grassroot level female medical staffs. METHODS: A total of 2 308 female medical workers from county, town and village in hengxian County of Guangxi Zhuang Autonomous Region were selected as study subjects by cluster sampling method. The basic information, occupational history, reproductive health and fertility of these subjects were investigated by Reproducetive Health Survey Questionnaine of Female Workers. RESULTS: The total prevalence of gynecological diseases in female medical staffs was 21.6%. Among them, the prevalence of genital tract infections was 15.6%, and gynecological tumors was 6.0%. The top three gynecologic diseases were vaginitis(9.2%), uterine fibroids(4.3%) and cervicitis(3.5%). Multivariate logistic regression analysis results indicated that the younger the patients, the higher the risk of reproductive tract infectious diseases(P<0.01), and the lower the risk of gynecological tumors(P<0.01). The risk of reproductive tract infectious diseases and gynecological tumors in married patients was higher than that in unmarried staffs(P<0.05). The higher the number of abortions, the higher the risk of reproductive tract infectious diseases and gynecological tumors(P<0.01). The risk of reproductive tract infectious diseases was higher and the risk of gynecological tumors was lower in female shift workers than that of non-shift workers(P<0.05). CONCLUSION: Vaginitis, uterine fibroids and cervicitis are the main gynecological diseases in grassroot level female medical staffs. The incidence of gynecological diseases is related to age, history of marriage, childbirth and abortion, and work-shifts.
