A nomogram prediction model was constructed for the meaningful variables included in the multivariate analysis, and the prediction model AUC was 0.88, the accuracy was 82.00 %, the precision was 77.78%, and the F1 value was 43.75%. The calibration plot fitted well, and the model had good discrimination and calibration.@*Conclusion@#The risk prediction model for left behind middle and high school students with PV has good predictive performance and is helpful for schools and communities to early identify high risk middle and high school students with PV.
ABSTRACT
Objective To study the evaluation value of lung injury score(LIS)and advanced glycation end products(AGEs)expression levels on the prognosis of elderly patients with sepsis-related acute lung injury/acute respiratory distress syndrome(ALI/ARDS).Methods A total of 98 elderly patients with sepsis-related ALI/ARDS admitted to First Branch of the First Affiliated Hospital of Chongqing Medical University from March 2019 to April 2021 were selected as the research group,and the patients were divided into two sub-groups according to their survival within 30 d after admission:the survival group(55 cases)and the death group(43 cases).Another 51 elderly patients with non-ALI/ARDS sepsis admitted to First Branch of the First Affiliated Hospital of Chongqing Medical University in the same period were selected as the control group.After admission,the clinical data of patients were recorded,and the levels of serum creatinine,troponin I,B-type brain natriuretic peptide(BNP),serum C-reactive protein(CRP)and procalcitonin(PCT)were de-tected.Enzyme-linked immunosorbent assay was used to determine the levels of AGEs in patients'serum.The LIS score was evaluated by LIS scale.With clinical factors as independent variables and prognosis as dependent variables,Logistic regression curve was used to analyze the death factors of elderly sepsis-related ALI/ARDS patients.Results AGEs levels,LIS scores,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)scores decreased sequentially in the death group,survival group,and control group(all P<0.05).The levels of lactic acid,blood glucose,troponin I,PCT,BNP and CRP in arterial blood of patients in the death group were significantly higher than those in the survival group and the control group(P<0.05).The results showed that arterial lactate,blood glucose,troponin I,PCT,BNP,CRP,AGEs,APACHE Ⅱ score,and LIS score were all independent risk factors for mortality in elderly sepsis-related ALI/ARDS patients(P<0.05).The area under the curve(AUC)of LIS score predicting prognosis in elderly sepsis-related ALI/ARDS pa-tients was 0.857(95%CI:0.821-0.911),and AUC of serum AGEs was 0.861(95%CI:0.809-0.908).LIS score and AGEs level had certain predictive value for the prognosis of elderly sepsis-related ALI/ARDS pa-tients.Conclusion The LIS score and AGEs level of the elderly patients with sepsis-related ALI/ARDS are independent risk factors of death,which have important predictive value for prognosis.
ABSTRACT
Objective To retrospectively investigate the efficacy of pelvic floor muscle training(PFMT)using APP-based home device in the real-world scenario.Methods A retrospective survey was conducted among 171 000 Chinese female users over 18 years old who freely registered APP and performed PFMT using a domestic manufactured home device from Oct 1,2019 to Mar 31,2021.The Patient Global Impression of Improvement(PGI-I)questionnaires concerning pelvic floor general condition,sexual satisfaction and other three major symptoms related to pelvic floor muscle laxity such as stress urinary incontinence(SUI),pelvic organ prolapse(POP),and vaginal laxity(VL)were broadcast public online for users to self-assess the improvement.The vaginal muscle strength values prior and post training recorded by APP were also reported.All data were collected anonymously for further stratified analysis.Results A total of 984 valid questionnaires were collected by systematic sampling.The PGI-I scores of pelvic floor general condition(P=0.000 1),sexual satisfaction(P=0.009),SUI(P=0.000 1),POP(P=0.044)and VL(P=0.034)were statistically significant in users who reported to use the device for 3 months or more compared with those less than 3 months.In addition,the increase of vaginal muscle strength was related to the improvement of PGI-I scores in SUI and POP with statistical significance.There were no significant difference in subgroups such as age,education,parity,and delivery mode.Conclusion The subjective benefit of pelvic floor function-related symptoms and the improvement of vaginal muscle strength could be observed after PFMT for three months or more using APP-based home device in Chinese women in the real-world scenario.
ABSTRACT
Objective To investigate the application value of single nucleotide polymorphism(SNP)linkage analysis based on next-generation sequencing(NGS)technology in preimplantation genetic testing(PGT)of families with autosomal recessive polycystic kidney disease(ARPKD).Methods A family with ARPKD was selected,where the female member had a pregnancy ultrasound revealing polycystic kidney in the fetus.Genetic testing showed compound heterozygous mutations of the polycystic kidney/polycystic liver disease 1 gene(PKHD1),c.10444C>T(paternal)and c.4303del(maternal),with the c.4303del mutation being reported for the first time.Targeting the coding region of the PKHD1 gene,335 high-density tightly linked SNP sites were selected in the upstream and downstream 2M regions using multiplex polymerase chain reaction(PCR)and NGS.The couple′s SNP risk haplotypes carrying gene mutations were constructed.After in vitro fertilization,blastocyst culture was performed.Trophoblastic cells obtained from the biopsy were subjected to whole-genome amplification,and NGS was used for linkage analysis and low-depth chromosomal aneuploidy screening of the embryos.Sanger sequencing was used to verify the results of embryo linkage analysis.Results Among the 6 biopsied embryos,4 were mutation-free and euploid,1 exhibited heterozygous for the mutation and mosaic while another unstable sequencing data,making it impossible to judge.One of the mutation-free and developmentally healthy euploid embryos was implanted into the maternal uterus,resulting in the full-term delivery of a healthy baby.Conclusion Application of NGS-based SNP linkage analysis in PGT can effectively blocking the vertical transmission of ARPKD within families,while avoiding abortion issues caused by aneuploid embryos.This study is also the first PGT report target-ing the PKHD1 gene c.4303del mutation.
ABSTRACT
With the development of digital technology， an increasing number of artificial intelligence （AI） technologies are being applied in the field of public health， significantly improving the efficiency of healthcare systems. However， such technological advancement also introduces a series of ethical risks. In this article， we conducted a systematic review by searching nine domestic and international databases and analyzing the ethical issues related to AI in public health， ultimately including 158 articles. Based on the analysis of the included literature， ethical risks were categorized into four aspects： data， algorithms， rights and responsibilities， and social impact. A total of 15 key issues were identified， among which privacy and confidentiality， informed consent， data security， and fairness， justice and inclusion emerged as the most prominent issues. The ethical challenges posed by AI in the field of public health cannot be ignored， and it is necessary to formulate ethical guidelines and practical recommendations for AI in this field， establish sound regulatory and review mechanisms， thereby ensuring the healthy development of AI research in public health.
ABSTRACT
BACKGROUND@#The addition of growth factiors is commonly applied to improve the osteogenic differentiation of stem cells. However, for human pluripotent stem cells (hPSCs), their complex differentiation processes result in the unknown effect at different stages. In this study, we focused on the widely used bone forming peptide-1 (BFP-1) and investigated the effect and mechanisms of its addition on the osteogenic induction of hPSCs as a function of the supplementation period. @*METHODS@#Monolayer-cultured hPSCs were cultured in osteogenic induction medium for 28 days, and the effect of BFP-1 peptide addition at varying weeks was examined. After differentiation for varying days (0, 7, 14, 21 and 28), the differentiation efficiency was determined by RT–PCR, flow cytometry, immunofluorescence, and alizarin red staining assays. Moreover, the expression of marker genes related to germ layers and epithelial-mesenchymal transition (EMT) was investigated at day 7. @*RESULTS@#Peptide treatment during the first week promoted the generation of mesoderm cells and mesenchymal-like cells from hiPSCs. Then, the upregulated expression of osteogenesis marker genes/proteins was detected in both hESCs and hiPSCs during subsequent inductions with BFP-1 peptide treatment. Fortunately, further experimental design confirmed that treating the BFP-1 peptide during 7–21 days showed even better performance for hESCs but was ineffective for hiPSCs. @*CONCLUSION@#The differentiation efficiency of cells could be improved by determining the optimal treatment period.Our study has great value in maximizing the differentiation of hPSCs by adding osteogenesis peptides based on the revealed mechanisms and promoting the application of hPSCs in bone tissue regeneration.
ABSTRACT
As the country with the largest number of new cancer cases and deaths,China faces a serious situation with a large cancer population base,low relative survival rate,and low adherence to cancer screening.Neighboring Japan,which has the longest life expectancy in the world,has a much higher relative survival rate than China,despite having a similarly high cancer rate,due to its well-established system of cancer prevention and control.Being an Asian country,the major prevalent cancers in China and Japan are similar in spectrum and can be referred to more.This article introduces the construction of Japan's cancer life-cycle prevention and control system of"cancer prevention","cancer care",and"coexistence with cancer"starting from the three major goals of Japan's cancer prevention and control program,and focuses on the improvement of cancer screening in Japan and the improvement of cancer survival in China.It also highlights the means and methods used to increase the cancer screening rate in Japan,with a view to providing suggestions for cancer prevention and control in China.
ABSTRACT
Objective:To explore the protective effect of 18α glycyrrhetinic acid (18α-GA) on acute ulcerative colitis (UC) induced by dextran sulfate sodium (DSS) in mice, providing theoretical and experimental basis for the clinical application of 18α-GA.Methods:Forty male C57BL/6J mice were randomly divided into 5 groups: DSS model group, positive drug control group, high, medium, and low dose groups of 18α-GA, with 8 mice in each group. The 5 groups of mice were continuously fed with 3% DSS solution for 7 days to establish an acute UC animal model. At the same time, each group was intraperitoneally injected with 100 mg/kg physiological saline, 100 mg/kg sulfasalazine, 40 mg/kg 18α-GA, 20 mg/kg 18α-GA, and 10 mg/kg 18α-GA daily. The weight of mice was measured and recorded daily, and the Disease Activity Index (DAI) of mice was evaluated. On the 8th day, the mice were euthanized and their colon length was measured; After slicing, the colon mucosa was observed and pathological scoring was performed; Western blot was used to detect the expression of NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome pathway related proteins in colon tissue; Enzyme linked immunosorbent assay (ELISA) was used to determine the content of interleukin(IL)-1β in colon tissue.Results:Compared with the DSS model group, the weight loss amplitude of the 18α-GA high and medium dose groups was significantly smaller on the 7th day (all P<0.05); Colon length was longer (all P<0.05), the pathological score of colon mucosa was significantly lower (all P<0.05); The expression of GSDMD, cleaved caspase1, and IL-1β in colon tissue was significantly lower (all P<0.05); The 18α-GA high-dose group had lower DAI scores ( P<0.05); The expression of NLRP3 was lower in colon tissue ( P<0.05). Conclusions:18α-GA can improve DSS induced acute ulcerative colitis in mice by inhibiting the activation of NLRP3 inflammasome pathway.

ABSTRACT
AIM: To explore the relationship between the changes of serum circFTO and microRNA-141-3p(miR-141-3p)levels and the different disease stages of diabetes retinopathy.METHODS: A total of 198 patients with type 2 diabetes admitted to our hospital from October 2019 to November 2022 were collected as the study subjects, the patients were grouped into non diabetes retinopathy(NDR)group(70 cases), non proliferative diabetes retinopathy(NPDR)group(66 cases)and proliferative diabetes retinopathy(PDR)group(62 cases)according to different stages; meantime, 67 volunteers with normal physical examination results were collected as the control group. The levels of serum circFTO and miR-141-3p were detected by real-time fluorescent quantitative PCR(qRT-PCR); Pearson correlation analysis was used to examine the correlation between the serum circFTO, miR-141-3p and various indicators in patients with diabetes retinopathy; multivariate Logistic regression analysis was applied to explore the influencing factors of diabetes retinopathy.RESULTS: CircFTO, systolic blood pressure(SBP), and diastolic blood pressure(DBP)in PDR group were higher than those in control group, NDR group and NPDR group, while miR-141-3p and high-density lipoprotein cholesterol(HDL-C)were lower than those in control group, NDR group and NPDR group(P<0.05). Fasting blood glucose(FPG)and glycosylated hemoglobin(HbA1c)in NDR group, NPDR group and PDR group were higher than those in the control group(all P<0.05). The course of disease in PDR group was longer than that in NDR group and NPDR group(P<0.05). Serum circFTO in patients with diabetes retinopathy was positively correlated with SBP, DBP, FPG, HbA1c, and miR-141-3p was negatively correlated with SBP, DBP, FPG, HbA1c(all P<0.05). CircFTO was a risk factor for diabetes retinopathy, and miR-141-3p was a protective factor for diabetes retinopathy(P<0.05).CONCLUSION: Serum circFTO is obviously increased and miR-141-3p is obviously decreased in patients with diabetes retinopathy, both of them are closely related to disease stage, and are expected to become important indicators for evaluating disease progress.
ABSTRACT
OBJECTIVE To further improve the rational drug use control mechanism based on performance appraisal， explore new paths of pharmaceutical care and promote the rational clinical drug use management to deepen development. METHODS The reform of pharmaceutical management system in our hospital was performed through implementing the “ten-point system of prescription behavior management”， supplemented by the two carriages of “strengthening prescription review” and “standardizing clinical medication”. By implementing a number of auxiliary measures such as man-machine integration pre-prescription review， improving pharmacists’ prescription review ability， optimizing prescription review mechanism in real time， regulating physicians’ off-label drug use behavior， and improving drug evaluation mechanism， pre-control and in-process intervention were completed. The evaluation results were incorporated into performance assessment by referring to the “ten-point system of prescription behavior management”， so as to realize multi-dimensional and fully closed-loop rational drug use management. The effects of management were evaluated by comparing the statistical results of related indexes before and after the management. RESULTS Compared with before management， irrational rate of prescriptions and medical orders in our hospital in 2022 decreased significantly， compared to the same period in 2020； the irrational rate of inpatient medical orders decreased from 5.00% in 2020 to 2.69% in 2022， and that of outpatient prescriptions decreased from 4.59% to 2.48%； the frequency of communication between clinical pharmacists and physicians increased； the times of clinical consultations increased from 16 to 58， and doctors’ acceptance of intervention for irrational drug use had improved from 52％ to 87％ ； physicians had a deeper understanding and recognition of clinical pharmaceutical care， the awareness of clinical rational drug use had been significantly improved. CONCLUSIONS The rational drug use control mechanism guided by performance appraisal further standardizes the issuance of prescriptions and medical orders， and makes physician-pharmacist cooperation more prominent， so as to realize the closed-loop pharmaceutical management of “pre- review， in-process supervision and post-evaluation”， and promote rational drug use in clinical practice.
ABSTRACT
Plasma nontargeted metabolomics technology was developed for investigating the effect and mechanism of improving kidney deficient in mice of Polygoni Multiflori Radix Praeparata. Thirty-five ICR mice were randomly divided into the control group, the model group, the BB24 h (braising with black bean sauce for 24 hours) group, the BB32 h group, and the BB40 h group. Biochemical indices in blood plasma of mice were measured by collecting eye blood after modeling. Changes in plasma endogenous metabolites of mice from each group were determined by ultra-performance liquid chromatography-linear trap quadrupole-orbitrap XL (UPLC-LTQ-orbitrap XL), and differential metabolites were screened. The results of pharmacodynamic investigation showed that compared to the model group, the levels of estradiol increased obviously in the BB24 h (P < 0.05), and the levels of cortisol increased obviously in BB32 h (P < 0.05). The hormone level of mice with kidney deficiency was significantly improved after taking processed Polygonum multiflorum. A total of 70 differential endogenous metabolites in blood plasma of mice were identified from all treatment groups, which mainly involved glycerophospholipid meta-bolism, arachidonic acid metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, and linoleic acid metabolism. The study indicated that Polygoni Multiflori Radix Praeparata may play the role of tonifying liver and kidney by improving the disorder of hypothalamic-pituitary-adrenal axis and regulating lipid metabolism in mice. Correlation analysis on differential metabolites in blood plasma and the chemical constituents showed that stilbene glycosides and saccharides may be the key pharmacodynamic material basis. The present study provides a new reference and theoretical foundation for revealing the potential pharmacodynamic material basis and mechanism investigation on tonifying liver and kidney of Polygoni Multiflori Radix Praeparata. This study was carried out following the ethical guidelines and regulations for the use of laboratory animals of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences and passed the animal experimental ethical review [No. SYXK (Jing) 2019-0003].
ABSTRACT
Objectives: To examine the influence of adjuvant chemotherapy after radical resection on the survival of patients with intrahepatic cholangiocarcinoma(ICC) and to identify patients who may benefit from it. Methods: The clinical and pathological data of 654 patients with ICC diagnosed by postoperative pathology from December 2011 to December 2017 at 13 hospitals in China were collected retrospectively. According to the inclusion and exclusion criteria,455 patients were included in this study,including 69 patients (15.2%) who received adjuvant chemotherapy and 386 patients (84.8%) who did not receive adjuvant chemotherapy. There were 278 males and 177 females,with age of 59 (16) years (M(IQR))(range:23 to 88 years). Propensity score matching (PSM) method was used to balance the difference between adjuvant chemotherapy group and non-adjuvant chemotherapy group. Kaplan-Meier method was used to plot the survival curve,the Log-rank test was used to compare the difference of overall survival(OS) and recurrence free survival(RFS)between the two groups. Univariate analysis was used to determine prognostic factors for OS. Multivariate Cox proportional hazards models were then performed for prognostic factors with P<0.10 to identify potential independent risk factors. The study population were stratified by included study variables and the AJCC staging system,and a subgroup analysis was performed using the Kaplan-Meier method to explore the potential benefit subgroup population of adjuvant chemotherapy. Results: After 1∶1 PSM matching,69 patients were obtained in each group. There was no significant difference in baseline data between the two groups (all P>0.05). After PSM,Cox multivariate analysis showed that lymph node metastasis (HR=3.06,95%CI:1.52 to 6.16,P=0.039),width of resection margin (HR=0.56,95%CI:0.32 to 0.99,P=0.044) and adjuvant chemotherapy (HR=0.51,95%CI:0.29 to 0.91,P=0.022) were independent prognostic factors for OS. Kaplan-Meier analysis showed that the median OS time of adjuvant chemotherapy group was significantly longer than that of non-adjuvant chemotherapy group (P<0.05). There was no significant difference in RFS time between the adjuvant chemotherapy group and the non-adjuvant chemotherapy group (P>0.05). Subgroup analysis showed that,the OS of female patients,without HBV infection,carcinoembryonic antigen<9.6 μg/L,CA19-9≥200 U/ml,intraoperative bleeding<400 ml,tumor diameter>5 cm,microvascular invasion negative,without lymph node metastasis,and AJCC stage Ⅲ patients could benefit from adjuvant chemotherapy (all P<0.05). Conclusion: Adjuvant chemotherapy can prolong the OS of patients with ICC after radical resection,and patients with tumor diameter>5 cm,without lymph node metastasis,AJCC stage Ⅲ,and microvascular invasion negative are more likely to benefit from adjuvant chemotherapy.
ABSTRACT
Objective: To explore the value of paraquat (PQ) intake, urine protein and myocardial enzyme indexes in judging the prognosis of patients with acute PQ poisoning. Methods: From September to December 2021, all 201 patients with acute PQ poisoning admitted to Guangzhou Twelfth People's Hospital from January 2010 to December 2019 were selected as the research objects. Based on follow-up results 60 days after poisoning, the research objects were divided into survival group (n=78) and death group (n=123) . The differences in information about poisoning, treatment plan, PQ intake, urine protein, creatine kinase, creatine kinase isoenzyme, lactate dehydrogenase, and α-hydroxybutyrate dehydrogenase between the two groups of patients were compared and analyzed. Logistic regression and Cox regression were used to analyze the correlation between poisoning outcome and PQ intake, urine protein and myocardial enzymes. ROC curve and principal component analysis were used to explore high-efficiency indicators for predicting the outcome of acute PQ poisoning. Results: The PQ intake[50 (20, 100) ml], urine protein (total rank 15570.50) , creatine kinase[ (336.36±261.96) U/L], creatine kinase isoenzyme[ (43.91±43.74) U/L], lactate dehydrogenase [ (346.01±196.50) U/L], α-hydroxybutyrate dehydrogenase content[ (271.23±11.92) U/L] of patients in the death group were all higher than the survival group[15 (10, 20) ml, 4730.50, (187.78±178.06) U/L, (18.88±15.50) U/L, (190.92±60.50) U/L, (152.60±48.34) U/L, respectively] (P<0.05) . The outcome of acute PQ poisoning was positively correlated with PQ intake, urine protein, creatine kinase, creatine kinase isoenzyme, lactate dehydrogenase, and α-hydroxybutyrate dehydrogenase (P<0.05) . Multivariate logistic regression and multivariate Cox regression analysis showed that creatine kinase, creatine kinase isoenzyme, lactate dehydrogenase and α-hydroxybutyrate dehydrogenase was positively correlated with the prognosis of patients with acute PQ poisoning (P<0.05) . ROC curve analysis and principal component analysis showed that the combined indexes of PQ intake, urine protein and myocardial enzymes had the highest efficacy and weight in judging the prognosis of patients (AUC=0.91, weight coefficient=0.19, sensitivity=0.76, specificity=0.89) . When the combined score was ≥4, the probability of accurately predicting the death of patients was as high as 91% (positive predictive value=0.91) . Conclusion: PQ intake, urine protein combined with creatine kinase, creatine kinase isoenzyme, lactate dehydrogenase, and α-hydroxybutyrate dehydrogenase has high value in predicting the prognosis of patients with acute PQ poisoning.

Superior labrum anterior posterior (SLAP) injury is a major challenge for orthopedic surgeons, due to the poor healing ability of the injured labrum. Although arthroscopic surgery is the gold standard for the treatment of SLAP injury, there are still disputes about the adaptation of different surgical techniques, the choice of anchors during operation, knotted or knotless anchors, and fixation methods. The authors believe that arthroscopic repair of SLAP lesions is effective for young patients with intact glenoid labrum(<35 years old) or with extensive activity, where single and knotless anchor is preferred. For the older patients(≥35 years old) with degeneration and wear of glenoid labrum, biceps tenodesis is more preferable, and interference screw fixation technique is recommended. As for patients with failed SLAP repair, biceps tenodesis can achieve a high success rate as a revision surgery. By review of the relevant literature in recent years, this paper summarizes the adaptation of different surgical methods of arthroscopic treatment of SLAP injury, intraoperative anchoring techniques, fixation methods and other improved surgical techniques.

We aimed to study radiomics approach based on biparametric magnetic resonance imaging (MRI) for determining significant residual cancer after androgen deprivation therapy (ADT). Ninety-two post-ADT prostate cancer patients underwent MRI before prostatectomy (62 with significant residual disease and 30 with complete response or minimum residual disease [CR/MRD]). Totally, 100 significant residual, 52 CR/MRD lesions, and 70 benign tissues were selected according to pathology. First, 381 radiomics features were extracted from T2-weighted imaging, diffusion-weighted imaging, and apparent diffusion coefficient (ADC) maps. Optimal features were selected using a support vector machine with a recursive feature elimination algorithm (SVM-RFE). Then, ADC values of significant residual, CR/MRD lesions, and benign tissues were compared by one-way analysis of variance. Logistic regression was used to construct models with SVM features to differentiate between each pair of tissues. Third, the efficiencies of ADC value and radiomics models for differentiating the three tissues were assessed by area under receiver operating characteristic curve (AUC). The ADC value (mean ± standard deviation [s.d.]) of significant residual lesions ([1.10 ± 0.02] × 10-3 mm2 s-1) was significantly lower than that of CR/MRD ([1.17 ± 0.02] × 10-3 mm2 s-1), which was significantly lower than that of benign tissues ([1.30 ± 0.02] × 10-3 mm2 s-1; both P < 0.05). The SVM feature models were comparable to ADC value in distinguishing CR/MRD from benign tissue (AUC: 0.766 vs 0.792) and distinguishing residual from benign tissue (AUC: 0.825 vs 0.835) (both P > 0.05), but superior to ADC value in differentiating significant residual from CR/MRD (AUC: 0.748 vs 0.558; P = 0.041). Radiomics approach with biparametric MRI could promote the detection of significant residual prostate cancer after ADT.

Objective: To investigate the association between triiodothyronine (T3) and inflammatory factors, and its potential effect on long-term outcomes in hospitalized patients with heart failure (HF). Methods: A total of 2 475 patients with HF admitted in Heart Failure Care Unit were consecutively enrolled in this retrospective cohort study from December 2006 to June 2018. Patients were divided into low T3 syndrome group (n=610, 24.6%) and normal thyroid function group (n=1 865, 75.4%). The median follow-up time was 2.9 (1.0, 5.0) years. A total of 1 048 all-cause deaths were recorded at the final follow-up. The effects of free T3 (FT3) and high-sensitivity C-reactive protein (hsCRP) on the risk of all-cause death were evaluated by Cox regression analysis and Kaplan-Meier analysis. Results: The age of the total population was 19-95 (57±16) years, 1 823 cases (73.7%) were male. Compared to those with normal thyroid function, albumin [(36.5±5.4) vs. (40.7±4.7) g/L], hemoglobin [(129.4±25.1) vs. (140.6±20.6) g/L], total cholesterol [3.6 (3.0, 4.4) vs. 4.2 (3.5, 4.9) mmol/L] (all P<0.001) were lower, Whereas age [(60.5±16.0) vs. (55.2±15.4) years], creatinine [105.0 (83.6, 137.0) vs. 87.8 (75.6, 106.3) mmol/L], log N-terminal B-type natriuretic peptide [(8.2±1.3) vs. (7.2±1.4) ng/L] were higher in LT3S patients (all P<0.001). In Kaplan-Meier survival analysis, patients with lower FT3 and higher hsCRP had significantly lower cumulative survival (P<0.001), lower FT3 combined with higher hsCRP subgroup had the highest risk of all-cause death (Ptrend<0.001). In multivariate Cox regression analysis, LT3S was an independent predictor of all-cause mortality (HR=1.40, 95%CI 1.16-1.69, P<0.001). Conclusion: LT3S is an independent predictor of poor prognosis in patients with heart failure. FT3 combined with hsCRP improve the predictive value of all-cause death in hospitalized patients with heart failure.

14 workers in the 1, 8-diaminonaphthalene workshop of a chemical company in Nantong City had symptoms or signs of varying degrees of pruritus and pigmentation of the face, neck and waist. Pathological examination of skin biopsies showed hyperkeratosis, the basal cells were liquefied and denatured. Seven workers were eventually diagnosed with occupational melanosis. To explore the causes of occupational melanosis caused by exposure to 1, 8-dinitronaphthalene and 1, 8-diaminonaphthalene, and to provide reference for the prevention and treatment of occupational melanosis in the future, this paper reported 14 cases of melanosis in the skin of workers in chemical industry.
