Objective:To study the regional distribution, temporal trend, and health inequity of burn incidence in the world from 1990 to 2019.Methods:The data related to burns worldwide from 1990 to 2019 were collected from the database of Global Burden of Disease (GBD). Based on the number of burn cases and age-standardized incidence rates, the incidence of burn was observed by age, region, socio-demographic index (SDI) area (divided into 5 categories of SDI areas: high, medium-high, medium, medium-low and low, the higher the area, the higher the degree of social development) and country, all of which were expressed as estimated values. Joinpoint regression analysis of the age-standardized incidence of burns from 1990 to 2019 was performed using Joinpoint 4.8.0.1 software to observe the average annual percentage change (AAPC). Rstudio software was used to analyze the Spearman correlation between the age-standardized incidence of burns and SDI from 1990 to 2019. The global inequities of burn incidence were evaluated using the slope index and concentration index from the health equity assessment toolkit, where the slope index reflected the absolute difference in burn incidence between countries with the lowest and highest SDI, and the concentration index indicated the degree to which burn incidence was concentrated in countries with low or high SDI.Results:From 1990 to 2019, the number of global burncases increased from 8 378 121.71 to 8 955 227.68, with an increase of 6.89%. However, the age-standardized incidence rate of burns showed an overall downward trend, from 149.86/100 000 in 1990 to 117.51/100 000 in 2019, with an AAPC of -0.80%. The incidence of burns in the population aged 10-19 years ranked the first in all age groups during the 30 years. Among the six regions of the world, the number of burn cases and the age-standardized incidence rate of burn in the Americas were the highest in 2019, but these two indexes were lower than those in 1999. In 2019, the number of burn patients in medium SDI areas was the highest, and the number of burn patients in low SDI areas was the lowest. The age-standardized incidence of burns was the highest in high SDI areas, and the lowest in medium-low SDI areas. From 1990 to 2019, the number of patients in high and medium-high SDI areas decreased, and the number of patients in other SDI areas increased. Compared with 1990, the age-standardized incidence rates of burns decreased in all SDI regions in 2019, with the greatest decline seen in high SDI and medium-high SDI regions. Cuba had the highest standardized incidence of burns, while Pakistan had the lowest. Spearman correlation analysis showed that from 1990 to 2019, the age-standardized incidence rates of burns in 204 countries and regions were positively correlated with SDI (all P<0.05), and the correlation coefficient decreased from 0.49 in 1990 to 0.37 in 2019. The health inequality slope index decreased from 212.90/100 000 in 1990 to 59.12/100 000 in 2019, and the concentration index decreased from 21.77% in 1990 to 8.38% in 2019. Conclusion:From 1990 to 2019, the global burn incidence rates are disproportionately concentrated in countries and regions with better development status. A significant reduction in the global burn incidence has been accompanied by a significant reduction in these inequities.

Objective:To investigate the cognitive function and its influencing factors among residents in Qingdao city.Methods:The 5 311 research subjects over 65 years old were selected from Qingdao by simple random sampling and stratified sampling. All subjects were investigated by AD8 dementia early screening questionnaire and community screening instrument dementia (CSI-D) to evaluate the prevalence of cognitive decline in this study.The score of AD8 dementia early screening questionnaire ≥2 points or the score of CSI-D ≤7 points was considered to be cognitive decline. Mann-Whitney U test, Chi-square test, Fisher exact probability method, univariate and multivariate Logistic regression analysis and Bootstrap verification were performed using SPSS 26.0 software. Results:Among 5 311 subjects, 1 899 subjects had normal cognitive function (35.76%) and 3 412 subjects had cognitive decline (64.24%). The age of the cognitive decline group was significantly higher than that of the normal group ( P<0.01). There were significant differences in gender, educational level, rural residents, marital status, chronic medical history, hypertension, rheumatoid arthritis, cerebrovascular disease, intervertebral disc disease, ischemic heart disease, monthly household income and alcohol consumption between the two groups (all P<0.05). Univariate Logistic regression analysis showed that female ( β=0.313, OR=1.367, 95% CI=1.221-1.530), age ( β=0.052, OR=1.053, 95% CI=1.043-1.063), rural residents ( β=0.850, OR=2.340, 95% CI=2.042-2.682), widowed ( β=0.557, OR=1.745, 95% CI=1.500-2.029), chronic medical history ( β=0.290, OR=1.336, 95% CI=1.191-1.498), hypertension ( β=0.134, OR=1.143, 95% CI=1.020-1.281), rheumatoid arthritis ( β=0.458, OR=1.581, 95% CI=1.222-2.046), cerebrovascular disease ( β=0.584, OR=1.794, 95% CI=1.352-2.380), intervertebral disc disease ( β=0.578, OR=1.782, 95% CI=1.370-2.319), ischemic heart disease ( β=0.501, OR=1.651, 95% CI=1.272-2.143) were the risk factors for cognitive decline. Higher education level, higher monthly household income and abstinence ( β=-0.244, OR=0.783, 95% CI=0.619-0.992) were protective factors for cognitive decline. Multivariate logistic regression analysis showed that age ( β=0.035, OR=1.036, 95% CI=1.025-1.047), rural residents ( β=0.215, OR=1.239, 95% CI=1.047-1.468), chronic medical history ( β=0.191, OR=1.210, 95% CI=1.067-1.372), cerebrovascular disease ( β=0.480, OR=1.616, 95% CI=1.195-2.187), intervertebral disc disease ( β=0.456, OR=1.578, 95% CI=1.190-2.094) were risk factors for Alzheimer's disease. Higher education level and higher monthly household income were protective factors for Alzheimer's disease. Conclusion:The elderly with chronic diseases, low income and low education level may be at the high risk of cognitive function decline, which should be paid attention to in early screening and intervention.

Background::Genetic variants of dopaminergic transcription factor-encoding genes are suggested to be Parkinson’s disease (PD) risk factors; however, no comprehensive analyses of these genes in patients with PD have been undertaken. Therefore, we aimed to genetically analyze 16 dopaminergic transcription factor genes in Chinese patients with PD.Methods::Whole-exome sequencing (WES) was performed using a Chinese cohort comprising 1917 unrelated patients with familial or sporadic early-onset PD and 1652 controls. Additionally, whole-genome sequencing (WGS) was performed using another Chinese cohort comprising 1962 unrelated patients with sporadic late-onset PD and 1279 controls.Results::We detected 308 rare and 208 rare protein-altering variants in the WES and WGS cohorts, respectively. Gene-based association analyses of rare variants suggested that MSX1 is enriched in sporadic late-onset PD. However, the significance did not pass the Bonferroni correction. Meanwhile, 72 and 1730 common variants were found in the WES and WGS cohorts, respectively. Unfortunately, single-variant logistic association analyses did not identify significant associations between common variants and PD. Conclusions::Variants of 16 typical dopaminergic transcription factors might not be major genetic risk factors for PD in Chinese patients. However, we highlight the complexity of PD and the need for extensive research elucidating its etiology.

Objective To observe the value of the scoring model of MRI features for predicting proliferative hepatocellular carcinoma(HCC).Methods Data of 241 patients with pathologically confirmed HCC,including 90 cases of proliferative HCC and 151 cases of non-proliferative HCC were analyzed retrospectively.Univariate and multivariate logistic regression were used to compare the clinical and MRI findings evaluated according to liver imaging reporting and data system version 2018 between groups.The independent predictive factors of proliferative HCC were screened,and scores were assigned according to the weight,then a scoring model was constructed.Receiver operating characteristic(ROC)curve was drawn,and the area under the curves(AUC)were calculated to assess the predictive efficacy of this model.The patients were divided into high and low proliferation risk subgroups based on the optimal score thresholds.The recurrence free survival(RFS)rates and early RFS rates were compared between groups and subgroups.Results MRI showed tumor corona enhancement,arterial phase annular hyper-enhancement,intratumoral vessels,much focus parenchymal low enhancement and irregular tumor margins were all independent predictive factors for proliferative HCC(OR=3.287,2.362,4.542,2.997,2.379,all P＜0.05),which were then were scored with 7,5,9,7 and 5,respectively,with a total score of 0-33.AUC of the obtained scoring model for predicting proliferative HCC was 0.818.Taken 9 points as the optimal score thresholds,97 cases were assigned into high proliferation subgroup and 144 into low proliferation risk subgroups).Significant differences of RFS rates and early RFS rates were found between groups and subgroups(all P＜0.05).Conclusion MRI features scoring model could effectively predict proliferative HCC.

Purpose To investigate the pathological characteristics of hepatocellular carcinoma(HCC)with irregular rim-like arterial phase enhancement(IRE)using gadoxetic acid-enhanced,and its early recurrence prognostic significance after surgery.Materials and Methods This retrospective study included 131 patients with surgically confirmed HCCs who underwent gadoxetic acid-enhanced MRI from February 2015 to September 2021 in the Third People's Hospital of Nantong.According to the enhancement pattern of gadoxetic acid-enhanced MRI in arterial phase,HCC were divided into IRE-HCC and non-IRE-HCC.Clinical,pathological and imaging characteristics were compared between IRE-HCC and non-IRE-HCC.Logistic regression analyses were performed to identify clinical,pathological and imaging features associated with IRE-HCC.Early recurrence(within 2 years)was evaluated by using Kaplan-Meier analysis.Cox regression analysis was performed to determine independent predictors of early recurrence.Results Cytokeratin 19(CK19)(OR=9.027,95%CI 2.533-32.170,P=0.001),microvascular invasion(OR=3.606,95%CI 1.024-12.701,P=0.046)and diffusion weighted imaging target signs(OR=10.370,95%CI 3.046-35.303,P=0.000)were independent predictors for IRE-HCC.The 2-year cumulative recurrence-free survival rate postoperative of IRE-HCC was 24.1%,which was significantly shorter than that of non-IRE-HCC(55.9%,χ2=19.971,P=0.000).Microvascular invasion(HR=2.206,95%CI 1.152-4.226,P=0.017)and IRE(HR=2.454,95%CI 1.408-4.275,P=0.002)were independent predictors of early postoperative recurrence of HCC.Conclusion IRE-HCC are associated with CK19,microvascular invasion and diffusion weighted imaging target signs,and have a high recurrence rate and poor prognosis in the early postoperative period.

Objective:To observe the clinical features of eyes in children with methylmalonic acidemia (MMA).Methods:A retrospective clinical case study. From June 2019 to June 2022, 13 children with MMA visited on the Department of Ophthalmology of Henan Children's Hospital were included in the study. The anterior segment and fundus were examined under surface or general anesthesia. Best corrected visual acuity (BCVA) and refraction were performed in 9 cases; fluorescein fundus angiography (FFA) was performed in 3 cases; flash electroretinogram (FERG) was performed in 6 cases; flash visual evoked potential (FVEP) was detected in 6 cases; optical coherence tomography (OCT) was performed in 3 cases.Results:Among the 13 pediatric patients with methylmalonic acidemia, 6 cases were male and 7 cases were female. The average age at first visit was 45 months. All cases suffered from hyperhomocysteinemia; 9 cases were with epilepsy; 2 cases were with infantile spasms; 11 cases were with stunting, 13 cases were with repeated pulmonary infection during growth period; 4 cases were with hydrocephalus; 1 cases was with hypertension and renal insufficiency. Genetic dectection results of 8 cases were recorded, MMACHC:c.609G>A:p.W203* mutation site was found in all cases. One case was accompanied by corneal ulcer. There were 10 cases with nystagmus, 4 cases with macular degeneration, 3 cases with hyperopic refractive error and esotropia. Nine cases underwent BCVA examination, BCVA was light perception-0.6. In OCT, 2 cases of 3 cases showed retinal thinning and photoreceptor cell layer atrophy in the macular area. In FFA, 2 cases of 3 cases showed circular transparent fluorescence in the macular area. Five cases of 6 cases who with FVEP had different degrees of P100 peak time delay and decreased amplitude, and 4 cases of 6 cases with FERG had decrease of a and b wave in light and dark adaptation. Conclusions:The clinical phenotypes of eyes in children with MMA are various and the severity was different; most of them are accompanied by nystagmus, and the fundus lesions are common in the characteristic bovine eye like macular region. Those with macular disease have severe visual impairment.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

Objective:To explore the prevalence and risk factors of sarcopenia in patients with maintenance dialysis (MHD).Methods:It was a cross-sectional study. Patients who received MHD treatment in the Blood Purification Center of Hainan Provincial People's Hospital in October 2019 were included as study subjects. The patients were divided into sarcopenia group and non-sarcopenia group according to whether they had sarcopenia or not. Chest CT imaging and laboratory examination data were collected. Dual-energy X-ray absorptiometry was used to measure the skeletal muscle mass. Chi-square test or Mantel-Haenszel trend chi-square test was used to compare the clinical data of patients with and without sarcopenia. Multivariate logistic regression equation was used to analyze the risk factors of sarcopenia.Results:A total of 182 MHD patients were enrolled in the study, and the prevalence of sarcopenia was 33.5% (61/182). The proportions of age ≥60 years old, diabetic nephropathy, tunneled-cuffed catheter, body mass index <18 kg/m 2, serum albumin <40 g/L, low density lipoprotein cholesterol ≥3.37 mmol/L, left ventricular ejection fraction <50%, chest CT-suspected pulmonary tuberculosis (PTB) and PTB in sarcopenia group were higher than those in non-sarcopenia group (all P<0.05). Multivariate logistic regression analysis results showed that left ventricular ejection fraction <50% (≥50% as a reference, OR=3.250, 95% CI 1.035-10.206, P=0.044), low-density lipoprotein cholesterol ≥3.37 mmol/L (<3.37 mmol/L as a reference, OR=6.354 ,95% CI 1.675-24.108, P=0.007), chest CT-suspected PTB (normal as a reference, OR=7.433, 95% CI 1.531-36.083, P=0.013), and PTB (normal as a reference, OR=28.871, 95% CI 3.208-259.872, P=0.030) were independent influencing factors of sarcopenia in MHD patients. Conclusions:The prevalence of sarcopenia is higher in MHD patients. Blood low-density lipoprotein cholesterol ≥3.37 mmol/L, ejection fraction <50%, chest CT-PTB and suspected PTB are independent risk factors of sarcopenia in MHD patients. Correcting left ventricular systolic function, regulating blood lipids and preventing PTB as early as possible can reduce the prevalence of sarcopenia in MHD patients.

Objective:To observe any effect of dry needling of myofascial trigger points on substance P and synaptophysin expression in the spinal dorsal horn.Methods:Sixty-four Sprague-Dawley rats were randomly divided into a control group ( n=16) and a model group ( n=48). Myofascial trigger points were induced in the model group by a blunt strike and eccentric running. That group was then randomly divided into a no-treatment group ( n=15), a massage group ( n=16), and a dry needling group (16 rats). The rats in the two treatment groups received 4 weeks of dry needling or Chinese massage. Pressure pain thresholds were recorded before the experiment and after the 4 weeks. The content of substance P and synaptophysin in the spinal dorsal horn were measured using immunoblotting and immunohistochemistry. Results:After the treatment 14 rats (93%) in the model group had trigger points, significantly higher than the 8 rats (50%) in the massage group and the 7 rats (44%) in the dry needling group. After treatment, the average pressure pain thresholds of the no-treatment and massage groups was significantly lower than the control group′s average, while the difference between the dry needling group and the control group was not significant. The average pressure pain threshold had improved significantly in the no-treatment group, the massage group and the dry needling group, and the averages of the massage group and the dry needling group were significantly higher than that of the no-treatment group. The level of substance P was significantly higher in the no-treatment group than in the other three groups and the ratio of substance P to Glyceraldehyde 3-phosphate dehydrogenase (GAPDH)was significantly higher. The substance P: GAPDH ratio of the massage group was significantly higher than that of the control group.Conclusions:Dry needling and massage are effective in relieving myofascial pain, at least in rats. Both can reduce the content of substance P in the spinal dorsal horn.
