ABSTRACT

PURPOSE@#To retrospectively analyze the clinical outcomes of meniscus repair with simultaneous anterior cruciate ligament (ACL) reconstruction and explore the causes of failure of meniscus repair.@*METHODS@#From May 2013 to July 2018, the clinical data of 165 patients who were treated with meniscus surgery and simultaneous ACL reconstruction, including 69 cases of meniscus repair (repair group) and 96 cases of partial meniscectomy (partial meniscectomy group) were retrospectively analyzed. The exclusion criteria were as follows: (1) ACL rupture associated with fracture, collateral ligament injury, or complex ligament injury; (2) a history of knee surgery; or (3) a significant degree of osteoarthritis. The 69 patients in the repair group were divided into the non-failure group (62 cases) and the failure group (7 cases) depending on the repair effect. Postoperative outcomes of the repair group and the partial meniscectomy group were compared. General conditions and postoperative outcomes of the failure group and the non-failure group were compared. During the median follow-up period of 28 months (range, 4 - 65 months) after the second arthroscopy, postoperative outcomes of seven patients in the failure group were summarized. SPSS 25.0 statistical software was used for statistical analysis. A p value less than 0.05 was considered statistically significant.@*RESULTS@#Seven patients in the failure group who underwent the second arthroscopy were followed up for (30 ± 17.4) months and their postoperative outcomes were summarized. Compared with the partial meniscectomy group, the International Knee Documentation Committee scores of patients in the repair group improved significantly (p = 0.031). Compared with the non-failure group, more patients in the failure group were younger than 24 years (p = 0.030). The median follow-up period was 39.5 months. All patients recovered well after subsequent partial meniscectomy and relieved clinical symptoms. Visual analog scale scores decreased significantly (p = 0.026), and the International Knee Documentation Committee and Lysholm scores improved significantly (p = 0.046 for both).@*CONCLUSION@#The failure rate of meniscus repair in this study was 10.1% (7/69), all of which were medial meniscus tears. However, the surgical outcomes of ACL reconstruction were not affected, and there might be a role for graft protection. Therefore, meniscus retears can be successful treated by performing subsequent partial meniscectomy in patients with repair failure.

ABSTRACT

Objective To identify the differentially expressed proteins in different liver tissues in the mouse model of alveolar echinococcosis using high-resolution mass spectrometry with data independent acquisition (DIA), and to identify the key proteins contributing to the pathogenesis of alveolar echinococcosis. Methods Protoscoleces were isolated from Microtus fuscus with alveolar echinococcosis and the experimental model of alveolar echinococcosis was established in female Kunming mice aged 6 to 8 weeks by infection with Echinococcus multilocularis protoscoleces. Mice were divided into the experimental and control groups, and animals in the experimental group was injected with approximately 3 000 protoscoleces, while mice in the control group were injected with the same volume of physiological saline. Mouse liver specimens were sampled from both groups one year post-infection and subjected to pathological examinations. In addition, the lesions (the lesion group) and peri-lesion specimens (the peri-lesion group) were sampled from the liver of mice in the experimental group and the normal liver specimens (the normal group) were sampled from mice in the control group for DIA proteomics analysis, and the differentially expressed proteins were subjected to bioinformatics analysis. Results A total of 1 020 differentially expressed proteins were identified between the lesion group and the normal group, including 671 up-regulated proteins and 349 down-regulated proteins, and 495 differentially expressed proteins were identified between the peri-lesion group and the normal group, including 327 up-regulated proteins and 168 down-regulated proteins. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that these differentially expressed proteins were involved in peroxisome, peroxisome proliferator-activated receptor (PPAR) and fatty acid degradation pathways, and the peroxisome and PPAR signaling pathways were found to correlate with liver injury. Several differentially expressed proteins that may contribute to the pathogenesis of alveolar echinococcosis were identified in these two pathways, including fatty acid binding protein 1 (Fabp1), Acyl-CoA synthetase long chain family member 1 (Acsl1), Acyl-CoA oxidase 1 (Acox1), Enoyl-CoA hydratase and 3-hydroxyacyl CoA dehydrogenase (Ehhadh) and Acetyl-Coenzyme A acyltransferase 1B (Acaa1b), which were down-regulated in mice in the experimental group. Conclusion A large number of differentially expressed proteins are identified in the liver of the mouse model of alveolar echinococcosis, and Fabp1, Acsl1, Acox1, Ehhadh and Acaa1b may contribute to the pathogenesis of alveolar echinococcosis.

ABSTRACT

Objective To identify the differentially expressed proteins in different liver tissues in the mouse model of cystic echinococcosis (CE), so as to provide insights into the research and development of therapeutic drugs targeting CE. Methods Female Kunming mice at ages of 6 to 8 weeks were randomly assigned into the CE group and the control group. Mice in the CE group were intraperitoneally infected with 2 000 Echinococcus multilocularis protoscoleces, while mice in the control group were injected with the same volume of physiological saline. All mice in both groups were sacrificed after breeding for 350 d, and the lesions (the lesion group) and peri-lesion specimens (the peri-lesion group) were sampled from the liver of mice in the CE group and the normal liver specimens (the normal group) were sampled from mice in the control group for data independent acquisition (DIA) proteomics analysis, and the differentially expressed proteins were subjected to Gene Ontology (GO) term enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Results A total of 26 differentially expressed proteins were identified between the lesion group and the normal group and between the peri-lesion group and the normal group, including 8 up-regulated proteins and 18 down-regulated proteins. GO term enrichment analysis showed that these differentially expressed proteins were predominantly enriched in endoplasmic reticulum membrane (biological components), oxidoreductase activity (molecular function) and oxoacid metabolic process and monocarboxylic acid metabolic process (biological processes). KEGG pathway enrichment analysis revealed that the differentially expressed protein Acyl-CoA oxidase 1 (Acox1), which contributed to primary bile acid biosynthesis during the fatty acid oxidation, was involved in peroxisome signaling pathway, and the differentially expressed protein fatty acid binding protein 1 (Fabp1), which contributed to fatty acid transport, was involved in the peroxisome proliferator-activated receptor (PPAR) signaling pathway. Conclusion Differentially expressed proteins are identified in the liver specimens between mouse models of CE and normal mice, and some differentially expressed proteins may serve as potential drug targets for CE.

ABSTRACT

Objective:To investigate the relationship between abdominal visceral adipose tissue (VAT) and cardiometabolic risk (CMR) through quantitative computed tomography (QCT).Methods:The present study included 76226 participants. Abdominal fat areas were measured using the QCT Pro Model 4 system. Cardiometabolic indices were collected, including systolic and diastolic blood pressures, fasting plasma glucose, total cholesterol, triglyceride, and low-density and high-density lipoprotein cholesterols CMR score was the sum of abnormal blood pressure, fasting glucose, triglyceride, and high-density lipoprotein cholesterol. Restricted cubic spline and ordered logistic regression models were applied.Results:The mean age was 50±13 years and the percentage of men was 58.8%. The level of VAT area was higher in men than in women (191.7±77.1 cm 2 vs 116.4±56.2 cm 2, P<0.0001 for all). After adjustment for age, the cardiometabolic indices except high-density lipoprotein cholesterol increased with increasing VAT area. When VAT area was 300 cm 2, age-adjusted odds ratios and 95% confidence intervals of a CMR score ≥ 1 were 14.61 (13.31, 16.04) for men and 5.46 (4.06, 7.36) for women, and the age-adjusted probability of a CMR score ≥ 3 was 31.7% for men and 31.3% for women. Conclusions:QCT-derived VAT is closely related to CMR. The findings suggest that measurement of visceral fat is recommended for the management of abdominal obesity in subjects who agree to undergo lung cancer screening via low-dose CT without additional radiation exposure.

ABSTRACT

Objective:To investigate the prevalence of carotid artery plaque (CP) in the population undergoing health examinations and to assess the association between CP and Helicobacter pylori (Hp) infection.Methods:The subjects were 3066 patients who underwent carotid ultrasonography examination and 13C urea breath test (UBT) at the health examination center of China-Japan friendship hospital from January 2019 to December 2019. The subjects were divided into CP and non-CP groups; the differences of physicochemical parameters and UBT positive rate between the two groups were analyzed by independent sample t test, Mann-Whitney U test, and Chi-squared test. The association between UBT positive and CP was analyzed by logistic regression. Results:The proportion of CP positive subjects was significantly higher in males than in females (33.4% vs 19.5%, P<0.001); the proportion of Hp positive subjects was not significant in sex composition (29.1% vs 30.9%, P=0.245); the age [(59.39±10.24) vs (46.44±9.88) years], P<0.01), BMI [(25.44±3.23) vs (24.21±3.54) kg/m 2, P<0.01], SBP [(135.91±19.07) vs (123.03±16.66) mmHg, P<0.01], DBP [(79.64±11.47) vs (75.10±11.55) mmHg, P<0.01], TC [(4.96±0.98) vs (4.86±0.98) mmol/L, P=0.004], TG [1.43 (1.03, 2.06) vs 1.20 (0.82,1.88) mmol/L, P<0.001], LDL-c [(3.21±0.93) vs (3.04±0.83) mmol/L, P<0.01)], FBG [5.55 (5.11,6.47) vs 5.16 (4.83,5.56) mmol/L, P<0.001], UA [(339.13±79.92) vs (319.85±87.62) mmol/L, P<0.01] and Hcy [13.10 (11.30,15.60) vs 11.7 (10.00,13.90) mmol/L, P<0.001] were significantly higher in the CP group than that in the non-CP group; HDL-c was significantly lower in the CP group than in the non-CP group [1.12 (0.95,1.32) vs 1.20 (1.00,1.43) mmol/L, P<0.001]. The proportion of male (62.4% vs 44.6%, P<0.01), prevalence of tobacco smoking (31.9% vs 19.6%, P<0.01), hypertension (33.8% vs 12.5%, P<0.01), and diabetes (13.45% vs 3.5%, P<0.01) were significantly higher in the CP group than that in the non-CP group. The proportion of UBT positive subjects was significantly higher in the CP group than in the non-CP group (34.5% vs 28.4%, P=0.001). Logistic regression analysis showed a significantly positive association between CP and UBT positive after adjusted confounding factors ( OR=1.270, P=0.028). Conclusions:The formation of CP is related to many risk factors; Hp infection is also an important risk factor. Controlling Hp infections might be one of the effective methods for the prevention and control of carotid plaque formation.

ABSTRACT

BACKGROUND@#As one of the most common endocrinal disorders for women at childbearing age, the diagnostic criteria of polycystic ovary syndrome (PCOS) have been defined differently among different international health organizations. Phenotypic heterogeneity of PCOS also brings about difficulties for its diagnosis and management assessment. Therefore, more efficient biomarkers representing the progression of PCOS are expected to be integrated into the monitoring of management process using metabolomic approaches.@*METHODS@#In this prospective randomized controlled trial, 117 PCOS patients were enrolled from December 2016 to September 2017. Classical diagnostic parameters, blood glucose, and metabolome were measured in these patients before and at 2 months and 3 months of different medical interventions. The receiver operating characteristic (ROC) curves were built based on multivariate statistical analysis using data at baseline and 3 months' management, and combinational biomarkers with appreciable sensitivity and specificity were selected, which then validated with data collected at 2 months.@*RESULTS@#A set of metabolites including glutamic acid, aspartic acid, 1-methylnicotinamide, acetylcarnitine, glycerophosphocholine, and oleamide were filtered out with high performance in representing the improvement through 3-month management of PCOS with high sensitivity and specificity in ROC analysis and validation with other two groups showed an appreciable area under the curve over 0.96.@*CONCLUSIONS@#The six metabolites were representative of the remission of PCOS through medical intervention, making them a set of potential biomarkers for assessing the outcome of PCOS management.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03264638.

ABSTRACT

OBJECTIVE@#To investigate the expression of microRNA-370 (miR-370) and microRNA-203 (miR-203) in the serum of patients with acute myeloid leukemia(AML), and to analyze its clinical diagnosis and prognostic significance.@*METHODS@#57 patients with acute myeloid leukemia were enrolled as experimental group, and 21 healthy people were enrolled as control group. The fasting venous blood of the personal in the two groups were collected. The expression of miR-370 and miR-203 of the personal in each groups were detected by real-time fluorescent quantitative PCR. The receiver operating characteristic (ROC) curve was plotted to detected the diagnostic values of serum miR-370, miR-203, and the Kaplan-Meier method was used to estimate the relationship between expression and overall survival of the patients.@*RESULTS@#Compared with healthy controls, serum miR-370 expression was significantly decreased in AML patients(P<0.05), and serum miR-203 expression was also significantly decreased (P<0.05). ROC curve analysis showed that the expression of serum miR-370 and miR-203 could be used to distinguish acute myeloid leukemia and healthy people. The area under the ROC curve of miR-370 was 0.909, and the sensitivity and specificity were 91.46% and 100.00%, respectively. The area under the ROC curve of miR-203 was 0.895, and the sensitivity and specificity were 83.45% and 89.71%, respectively. Serum levels of miR-370 and miR-203 were closely related to overall survival in AML patients.@*CONCLUSION@#The expression of miR-370 and miR-203 is decreased in the serum of patients with AML and may be a new markers for the diagnosis and prognosis of AML.

ABSTRACT

Objective To understand the status of knowledge, attitude and practice on echinococcosis prevention and control and investigate their influencing factors among residents living in Seda County of Sichuan Province, so as to provide a scientific basis for the further implementation of health education interventions in the county. Methods A multi-stage stratified random sampling method was employed on September 2018. Ten townships were randomly sampled, and 2 to 3 administrative villages were randomly sampled from each township. Then, 20 to 40 households were randomly sampled from each village, and 1 to 2 villagers were investigated in each household. The knowledge, attitude and practice on echinococcosis prevention and control were investigated using a household questionnaire survey, and the factors affecting the qualification of echinococcosis prevention and control knowledge were identified using chi-square test and logistic regression analysis. Results A total of 760 questionnaires were assigned, and 748 effective questionnaires were recovered, with a recovery rate of 98.42%. The overall qualification rate of echinococcosis prevention and control knowledge was 56.42% (422/748) in residents living in Seda County, and the awareness of the question “How to get echinococcosis?” was only 48.40%. The proportion of subjects with a positive attitude towards echinococcosis prevention and control was 64.71% to 94.79%, and the rate of corrected echinococcosis prevention and control behaviors was 10.40% to 82.45%. Univariate analysis showed that factors affecting the qualification rate of echinococcosis prevention and control knowledge included gender, occupation, education level, frequency of echinococcosis screening and frequency of health education (all P < 0.05), and binary logistic regression analysis showed that women, herdsmen as the primary occupation, an education level of primary school and below, absence of echinococcosis screening and absence of health education were factors responsible for the unqualified awareness of echinococcosis prevention and control knowledge (all P < 0.05). Conclusions There is a low awareness rate of echinococcosis prevention and control knowledge and a low proportion of corrected echinococcosis prevention and control behaviors in residents living in Seda County, Sichuan Province. Multiple forms of health education activities pertaining to echinococcosis prevention and control are needed with adaptation to local circumstance, and implementation of appropriate behavioral interventions is recommended.

ABSTRACT

Objective:To investigate the incidence, risk factors and survival of cGVHD patients in combination of a haploidentical donor supported with an unrelated umbilical cord blood for hematopoietic stem cells transplantation (haplo-cord-HSCT).Methods:300 hematological malignancies individuals who received dual transplantation were enrolled in the study between January 2012 and July 2016 at the department of Hematology in the First Affiliated Hospital of Soochow University. The clinical diagnosis and scoring the severity of cGVHD syndromes according the National Institutes of Health (NIH) consensus conference in the 2014 update. Cox proportional hazards regression was used to identify risk factors associated with transplant outcomes.Results:During follow-up with a median time of 26.4 months (range 0.2-61.8) post transplantation, the 1-year, 3-year and 5-year cumulative incidence of cGVHD was 26.3 % (95 % confidence interval [CI], 23.5 %~29.1 %), 30.3 % (95 % CI, 27.3 %~33.3 % ) and 32.2 % (95 % CI, 28.7 %~35.7 %). For all 73 patients with cGVHD, first-line or second-line treatment were given. During the follow-up period, 53 patients survived, and 20 patients died. In multivariate analysis, the cGVHD overall survival (GOS) were associated with thrombocytopenia(<100×109/L)(HR=0.103, 95 % CI 3 %-36.1 %, P<0.001). Conclusions:Our data suggest that, the 5-year cumulative incidence of cGVHD was 32.2 % after haplo-cord-HSCT with hematological malignancies. Thrombocytopenia (<100×109/L)was independent risk factors for GOS.

ABSTRACT

Plant trichomes are special structures that originate from epidermal outgrowths. Trichomes play an important role in plant defense against pests and diseases, and possess economic and medicinal values. Study on molecular mechanism of plant trichomes will contribute to the molecular design breeding and genetic improvement of crops. In recent years, the regulation mechanism of trichome development has been basically clarified in the model plant Arabidopsis thaliana, while great progresses are also found in other plant species. In this review, we focus on the developmental regulation of trichome formation from gene and phytohormones levels in Arabidopsis and cotton (with unicellular trichomes), as well as in tomato and Artemisia annua (with multicellular trichomes). The research progress associated with trichomes is also introduced in other typical monocotyledons and dicotyledons. Finally, the research and application of plant trichomes are prospected.

ABSTRACT

OBJECTIVE@#To evaluate the effects of Chinese medicine Dingkun Pill () alone or in combination with Diane-35 on patients with polycystic ovary syndrome (PCOS).@*METHODS@#This is a prospective randomized controlled trial conducted at Peking Union Medical College Hospital Beijing, China, from December 2016 to September 2017. Totally 117 PCOS patients were randomly assigned to the Dingkun Pill group (38 cases), Diane-35 group (40 cases), or combined group (39 cases). Patients in the Dingkun Pill group or Diane-35 group took daily 7 g of oral Dingkun Pill or 1 tablet of oral Diane-35, respectively, for 21 consecutive days followed by 7 drug-free days. And the combined group received a combination of Dingkun Pill and Diane-35. The treatment course was 3 months. Fasting plasma glucose and insulin, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), free fatty acids (FFA) and sex hormones were analyzed, quantitative insulin sensitivity check index (QUICKI) was calculated, and menstruation and acne scores were recorded at baseline and after 3-month treatment.@*RESULTS@#Compared with before treatment, QUICKI decreased significantly in the Dingkun Pill and combined groups after 3-month treatment (P0.05).@*CONCLUSIONS@#Dingkun Pill showed better effects than Diane-35 in improving insulin sensitivity, lowering TC and FFA. Diane-35 was more efficient in regulating menstruation and lowering androgen than Dingkun Pill. Combination of Dingkun Pill and Diane-35 may be a better choice to regulate menstruation, lower androgens while improve glucose metabolism in PCOS patients.

ABSTRACT

Systematic evaluation of the effectiveness and safety of Xiaoer Xiaoji Zhike Oral Liqud combined with azithromycin in the treatment of mycoplasma pneumonia in children. Clinical literatures were retrieved from PubMed, Cochrane Library, EMbase, VIP, CNKI, SinoMed, WanFang from inception to September 2019. Two reviewers independently screened out the literatures, extracted data and assessed the risk of bias of the included studies. Then, Meta-analysis was performed by RevMan 5.3 software. A total of 17 RCT were included, involving 1 712 patients. In this study, there were two subgroups by the application approach of azithromycin: oral azithromycin subgroup and intravenous azithromycin subgroup. According to Meta-analysis results, in terms of the alleviation of clinical symptoms and signs, such as shortening of antifebrile time, cough disappeared time, rales disappearance time, and lung X-ray infiltrating shadow disappearance time, Xiaoer Xiaoji Zhike Oral Liquid combined with oral azithromycin or intravenous azithromycin were better than single-dose azithromycin; in the aspect of the improvement of the overall effective rate, the two combination subgroups were better than the single-use azithromycin; In terms of the decline of IgM, the combination subgroups were also more efficient than the single-use azithromycin, with statistically significant differences. In terms of the incidence of adverse reactions, there was no significant difference between the two combination subgroups and the single-use azithromycin in children, and no serious adverse reactions were found. In inclusion, Xiaoer Xiaoji Zhike Oral Liquid combined with azithromycin can improve the clinical efficacy in treating pediatric mycoplasma pneumonia, with a high safety. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.

ABSTRACT

OBJECTIVE: To determine and compare the contents of catalpol and aucubin in different parts (root, stem, leaf and flower) of wild Centranthera grandiflora, and to provide reference for the selection of medicinal parts and source development. METHODS: HPLC method was used to determine the contents of catalpol and aucubin in root, stem, leaf and flower of wild C. grandiflora, and the contents of different parts were analyzed comparatively. The determination of catalpol was performed on Agilent TC-C18 column with mobile phase consisted of methanol-0.1% phosphoric acid (1 ∶ 99, V/V) at the flow rate of 1 mL/min; the detection wavelength was set at 210 nm, and sample size was 20 μL. The column temperature was 35 ℃; the determination of aucubin was performed on SPHERI-5RP-C18 column with mobile phase consisted of acetonitrile-water (3 ∶ 97, V/V) at the flow rate of 1 mL/min; the detection wavelength was set at 205 nm, and sample size was 20 μL; the column temperature was 25 ℃. RESULTS: The linear range of catalpol and aucubin were 0.061 5-3.321 and 0.000 36-0.216 mg/mL (all r=0.999 9). The limits of detection were 0.016 and 0.007 μg/mL. The limits of quantitation were 0.052 and 0.023 μg/mL. RSDs of precision, stability (24 h) and reproducibility tests were all lower than 2.00% (n=6). The average recoveries were 99.34% and 99.61%, and RSDs were 1.06% and 1.12%, respectively (n=6). The average content of catalpol in root, stem, leaf and flower wild C. grandiflora were 1.609, 3.030, 11.095 and 1.921 mg/g, respectively. The contents of aucubin in different parts were 0.441, 0.020, 0.005 and 0.006 mg/g,respectively. CONCLUSIONS:The established HPLC method meets the requirements of quantitative analysis. Catalpol is mainly distributed in the leaves of wild C. grandiflora, and aucubin is mainly distributed in the roots of wild C. grandiflora. The experimental conclusion provides a reference for the reasonable selection of different medicinal parts as raw materials to develop medicine with different efficacy.

ABSTRACT

OBJECTIVE: To design and synthesize N-aroyl substituted indoline-3-acetic acid derivatives and evaluate their in vitro hypoglycemic activity. METHODS: Using indoline derivative 2-[5-(benzyloxy)-1-(4-chlorobenzoyl)-2-methyl-1H-inclol-3-yl]acetic acid (GY3) as leading compound, 4-(benzyloxy)phenyl hydrazine hydrochloride and methyl 4-oxopentanoate as raw material, 8 kinds of N-aroyl (3-hydroxybenzoyl, 3-cyanobenzoyl, 4-nitrobenzoyl, 4-methylsulfonylbenzoyl, 4-acetamidobenzoyl, 3-acetylaminobenzoyl, isoniacyl and pyridine-2-formyl) substituted indoline-3-acetic acid derivatives were synthesized via 4 steps reactions: Fischer indole cyclization, reduction, amidation and hydrolyzation. The human hepatoma HepG2 cell lines were used to investigate the glucose consumption activity of the target compounds. RESULTS: Totally 8 various N-aroyl substituted indoline-3-acetic acids were synthesized and their structures were confirmed by mass spectrum(MS), nuclear magnetic resonance 1H-NMR and 13C spectrum. Under the condition of 1.0 μmol/L, the percentage of glucose- promoting consumption of the synthesized compounds on HepG2 cells was 5.4%-9.1%. 2-[(2R, 3S)-5-benzyloxy-2-methyl-1-(4-methylsulfonyl benzoyl)-2,3-dihydro-indole-3-yl] acetic acid showed the best hypoglycemic activity. The percentage of glucose- promoting consumption was (9.1±1.81)%, which was close to that of positive control metformin [(10.58±1.68)%], but less potent than that of leading compound GY3[(12.15±0.78)%]. CONCLUSIONS: Different electron-withdrawing substituents are introduced into N-aroyl aromatic rings of dihydroindole compounds, such as cyano, nitro, methyl sulfonyl; hypoglycemic activity decreases in varying degrees and is weaker than halogen substituents.

ABSTRACT

Objective To investigate the correlations of risk factors of age,delirium-inducing factors,dementia,delirium severity,and disease severity with the prognosis of elderly patients with delirium.Methods A total of 112 patients aged 70 years and older with initial onset of delirium during hospital stay were enrolled in this study.They were hospitalized in Dalian Municipal Central Hospital from Jan.2013 to Dec.2015.The severity of delirium was evaluated by delirium rating scalerevised-98(DRS-R-98).The acute physiology and chronic health enquiry(APACHE-Ⅱ)score and the sequential organ failure assessment(SOFA)score were recorded within 48 h after delirium onset.After periods of hospitalization of Jan.2013 to Dec.2015,patients were followed up until 31 Dec 2017.Correlations of age,delirium-inducing factors and dementia with survival time and long-term viability after delirium onset were statistically analyzed.Results Age,delirium-inducing factors,cognitive impairment,duration of cognitive impairment,type of dementia,and delirium severity had no correlations with the lifetime and long-term viability in patients with delirium.While,APACHE Ⅱ score for assessment of severity degree of delirium(P <0.001,r =-0.390) and SOFA score(P <0.001,r=-0.638)were negatively correlated with the lifetime in patients with delirium.SOFA score (P =0.004) and delirium recurrence (P < 0.001) were significantly correlated with the long-term viability in patients with delirium.Conclusions The severity and recurrence of delirium are strongly correlated with the lifetime and quality of life in patients with delirium.Compared with APACHE Ⅱ score,SOFA score may have a more important clinical application value in predicting the prognosis of patients with delirium.

ABSTRACT

Objective Lung cancer is one of the most common types of malignancy, and the incidence and mortality are the highest among cancers. Increasing the diagnostic rate of early-stage lung cancer is very important to improve the prognosis of patients. The occurrence and development of lung cancer is a complex process mediated by multiple genes and multiple signaling pathways. The detection of biomarkers has received great attention in the early diagnosis of lung cancer. With the deepening of research and advances in detection technology, biomarkers such as autoantibodies, exosomes, circulating tumor cells, circulating tumor DNA, and DNA methylation of lung cancer have been continuously discovered, and precision medicine has been deeply rooted in the hearts of people. This article gives an overview of the research progress of biomarkers in the early diagnosis of lung cancer.
