Tenosynovial giant cell tumor (TGCT) is a rare mesenchymal tumor that clinically presents as nodular-type or diffuse-type (D-TGCT). D-TGCT is more aggressive, has a higher surgical recurrence rate, and can potentially lead to severe joint destruction. The traditional treatment is primarily through surgical intervention. Recent advancements in understanding the molecular mechanisms of the disease and the development of new drugs have significantly changed TGCT treatment strategies. Drug therapy and active surveillance have become important treatment options for unresectable or high-recurrence-risk TGCT. Imaging examinations and patient-reported outcome tools play a crucial role in evaluating efficacy and guiding treatment decisions. Comprehensive management by a multidisciplinary team and utilizing individualized treatment plans can significantly improve the quality of life and treatment outcomes of patients. Future research should explore the molecular mechanisms of TGCT, enhance multidisciplinary collaboration, and emphasize long-term management to improve treatment efficacy and patient prognosis.

Objective:To understand the epidemiological characteristics and trends of injury in older adults in Jiangsu Province from 2006 to 2022 and provide a scientific basis for developing prevention and control measures.Methods:The data on injury cases aged 60 and older were collected from 12 sentinel hospitals in Jiangsu Province during 2006-2022. The study analyzed the proportion of injury cases among the elderly in the overall population and calculated the annual percent change and average annual percent change (AAPC). A pairwise comparison between groups was performed, and the differences were judged according to the adjusted standardized residuals.Results:From 2006 to 2022, there were 218 426 injury cases among individuals aged 60 and older in Jiangsu Province, which accounted for an increasing proportion of injury cases within the entire population (AAPC=3.17%, P<0.001). The first five causes of elderly injury were falls (42.06%), road traffic injuries (20.20%), animal injuries (11.45%), knife/sharp injuries (9.43%), and blunt injuries (8.13%). From 2006 to 2022, the proportion of falls, animal injuries, and knife/sharp injuries among the elderly aged ≥60 showed an increasing trend, while the proportion of road traffic injuries and blunt injuries decreased (all P<0.001). The incidence of injury was highest in October, with a daily incidence peak between 8:00 and 10:00. Leisure activities (40.34%) were the major activity leading to injury. The injury occurred mainly at home (53.74%), and the injury intention was mainly unintentional (97.41%), all of which showed an increasing trend ( P<0.001). The injuries were mainly bruises (36.00%), and the most common injured positions of the body were low limbs (27.55%), all of which showed a decreasing trend ( P<0.001). About 69.80% of cases were slight, and 79.38% were discharged after treatment, which showed an increasing trend ( P<0.001). Conclusions:The injury data for individuals aged 60 and older in Jiangsu Province exhibited varying trends from 2006 to 2022. There was a noticeable increase in the proportion of elderly injury cases within the overall injury population, as well as an upward trend in falls, animal injuries, and knife/sharp injuries as leading causes of injury. It is imperative to actively develop prevention measures based on the epidemiological characteristics and evolving trends of elderly injuries in Jiangsu Province.

Objective:To investigate the detection status and genotypes distribution characteristics of norovirus(NoV)in environmental sewage from three monitoring points in Fujian province, and to explore the significance of its application to NoV monitoring.Methods:Sewage samples were collected monthly at 5 sampling sites in representative monitoring cities, enriched and concentrated. Partial gene fragments of norovirus VP1 were amplified by reverse transcription-semi nested polymerase chain reaction (RT-snPCR), TA cloned and sequenced. Genotypes were identified based on the sequencing.Results:A total of 56 sewage samples were collected from July 2022 to June 2023. The detection rates of GⅠ and GⅡ were 89.29% (50/56) and 94.64% (53/56), respectively. A total of 7 NoV GⅠ genotypes and 13 GⅡgenotypes were identified. GⅠ.1, GⅠ.4, GⅡ.4 and GⅡ.17 were the dominant genotypes. NoV genotypes detected in different sampling sites were not exactly the same. The detection rate of NoV was low from August to November 2022, and the prevalence of the dominant genotypes was different in different seasons. GⅠ.1 and GⅡ.4 were highly prevalent from August to November 2022, but were replaced by GⅠ.4 and GⅡ.17 from December 2022 to June 2023, respectively. More NoV genotypes were detected in January-June 2023, comparing to the July-December 2022. The dominant genotype GII.17, has multiple clades and new variants have been discovered that are different from the 2014/2015 circulating strains.Conclusions:The detection rates of NoV in environmental sewage were very high, and genotypes were diverse. Environmental sewage surveillance could be an important complementary method for NoV cases surveillance.

Objective:To systematically evaluate the impact of sexual health education on the sexual quality of life, sexual satisfaction, anxiety, depression and the quality of life in breast cancer patients.Methods:A comprehensive search was conducted in Cochrane Library, Embase, PubMed, CNKI, Wanfang Data, VIP, and SinoMed databases for randomized controlled trials (RCTs) exploring the effects of sexual health education on sexual quality of life, sexual satisfaction, anxiety, depression and quality of life in breast cancer patients. The search covered studies up until November 8, 2023. Two researchers independently screened the literature, extracted data, and assessed the quality of the RCTs using the Cochrane Handbook 5.1.0 risk of bias tool. Meta-analysis was performed using RevMan 5.4 and R4.3.2 software.Results:A total of 17 articles with 1 695 patients were included. Sexual health education significantly improved sexual quality of life [ SMD=1.25, 95% CI (0.65, 1.84), P<0.05], sexual satisfaction [ SMD=0.85, 95% CI (0.53, 1.17), P<0.05], depression [ SMD=-1.16, 95% CI (-2.01, -0.30), P<0.05], and the quality of life [ SMD=1.53, 95% CI (0.09, 2.97), P<0.05] in breast cancer patients. However, the improvement in anxiety was not statistically significant [ SMD=-0.88, 95% CI (-2.06, 0.29), P<0.05] . Conclusions:Sexual health education can improve the sexual quality of life, sexual satisfaction, depression, and the quality of life in breast cancer patients. However, its impact on anxiety remains unclear, possibly due to the limited number of studies. Future RCTs should further explore the effect of sexual health education on anxiety in this population.

Objectives:To explore the impact of intensive lipid-lowering strategy on short-term prognosis of acute coronary syndrome(ACS)patients with multi-vessel disease. Methods:A total of 136 ACS patients with multi-vessel disease who received coronary stenting at Zhongnan Hospital of Wuhan University from August 2019 to November 2020 were enrolled in this study.Patients were divided into intensive lipid-lowering group(control low density lipoprotein cholesterol[LDL-C]below 1.0 mmol/L within 3 months,and continuously meet the standards within 12 months,n=69)or standard lipid-lowering group(gradually control LDL-C below 1.4 mmol/L within one year,n=67).The total cholesterol(TC),triglycerides(TG),LDL-C,high-density lipoprotein cholesterol(HDL-C),and lipoprotein(a)(Lp[a])data were collected.Incidence of major adverse cardiovascular events(MACE,including cardiac death,myocardial infarction,target vessel revascularization and stroke)were observed during 12 months of follow up. Results:The baseline data of the intensive lipid-lowering group and the standard lipid-lowering group were consistent before intervention.At the timeline of enrollment,there was no statistically significant difference in the blood lipid profiles(including TC,TG,LDL-C,HDL-C)between the two groups.After 3-months,patients in the intensive lipid-lowering group experienced significantly lower TC,TG,LDL-C and Lp(a)compared with baseline values(all P<0.05),while HDL-C remained unchanged(P>0.05).The standard lipid-lowering group showed a significant decrease in TC and LDL-C compared with baseline values(both P<0.05).The TC and LDL-C levels were significantly lower in the intensive lipid-lowering group than in the standard lipid-lowering group at 3/6/12 months follow up after discharge(all P<0.01).At 12 months follow-up,Kaplan-Meier survival analysis showed that the incidence of MACE was significantly lower in the intensive lipid-lowering group than in the standard lipid-lowering group(2.90%vs.14.93%,χ2=6.090,P=0.014).Multiple Cox regression analysis revealed that the intensive lipid-lowering strategy significantly reduced the risk of MACE compared with the standard lipid-lowering strategy(HR=0.177,95%CI:0.037-0.838,P=0.029). Conclusions:Our data show that intensive lipid-lowering strategy may probably reduce the incidence of short-term MACE in ASC patients with multi-vessel disease.Large-scale prospective multi-center studies are needed to further validate these results.

Multiple thrombosis in the coronary arteries need to be characterized by a thorough determination of the source of the thrombus to distinguish them as thrombosis or coronary embolism.This case was a 38-year-old male patient with chest pain and an electrocardiogram showing acute inferior wall and right ventricular myocardial infarction.Emergency coronary angiography showed thrombosis in the proximal middle of the left anterior descending artery,the opening of the first diagonal artery,and the middle of the right coronary artery,but no obvious stenosis was seen.Postoperative electrocardiogram showed acute inferior wall,right ventricular and anterior wall myocardial infarction,and intensive antithrombotic treatment was applied,elective re-examination of coronary angiography and intraluminal imaging showed mixed plaques and suspicious intimal dissection,indicating the possibility of thrombosis secondary to unstable plaque and coronary dissection,and intensive drug treatment was given.After discharge,the patient was stable during the regular follow-up visits.

Objective To establish a method to quantify serum fat-soluble vitamins by liquid chromatography-tandem mass spectrome-try and evaluate their performance in preliminary clinical application.Methods The contents of fat-soluble vitamin in serum were quantified by liquid chromatography-tandem mass spectrometry.The samples were collected from 1 113 pregnant women from November 2022 to November 2023 at the Obstetrics Clinic of the First Affiliated Hospital of Soochow University.The method of liquid chromatog-raphy-tandem mass spectrometry for determination of fat-soluble vitamins in serum was validated referring to"Consensus of method de-velopment and validation of liquid chromatography-tandem mass spectrometry in clinical laboratories".Results The linear ranges of vitamin A,E,D2,D3 and K1 in serum were from 40 to 4 000 ng/mL,0.5 to 50 μg/mL,2 to 200 ng/mL,5 to 250 ng/mL and 0.1 to 10 ng/mL,respectively.The detectable limit was 2.50 ng/mL,0.10 ng/mL,0.40 ng/mL,1.00 ng/mL and 0.02 ng/mL,respec-tively.The limit of quantitation was 10.00 ng/mL,0.50 ng/mL,1.00 ng/mL,5.00 ng/mL and 0.10 ng/mL,respectively.The intra-batch coefficient of variation(CV)and inter-batch CV were all less than 15％.The rate of recovery was 91.25％to 107.18％,90.00％to 105.51％,92.88％to 107.87％,93.36％to 107.40％and 90.20％to 104.40％,respectively.The various fat-soluble vitamins in ser-um remained stable within 7 days under-20 ℃.The levels of fat-soluble vitamins in serum of pregnant women were detected by liquid chromatography-tandem mass spectrometry.There were significant differences of the levels and distributions for various fat-soluble vita-mins in the pregnant women in different age groups(P＜0.05),and the levels of fat-soluble vitamins gradually increased with the age.Conclusion The basic performance of the liquid chromatography-tandem mass spectrometry verified in this experiment was in line with the evaluation criteria,thus it should be highly sensitive and accurate for analyzing the contents of various fat-soluble vitamins in serum.

Objective:To investigate the expression level of small nucleolar RNA SNORD15A in bone marrow of patients with acute leukemia (AL) and its relationship with clinical characteristics and prognosis of patients.Methods:Bone marrow blood samples of 53 newly treated AL patients and 29 healthy subjects without clinical diagnosis of hematologic diseases or other malignant diseases (control group) at the Affiliated Hospital of Guangdong Medical University from March 2018 to December 2021 were collected. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the relative expression of SNORD15A in bone marrow blood mononuclear cells of the two groups. The median relative expression of SNORD15A (0.148) was used as the boundary, and AL patients were divided into low expression group (<0.148) and high expression group (≥0.148). The relationship between the expression level of SNORD15A and the clinical characteristics, clinical indicators and overall survival (OS) of AL patients was analyzed. Kaplan-Meier method was used for survival analysis and log-rank test was performed; Cox proportional hazards model was used for univariate and multivariate analyses of OS of patients.Results:The relative expression of SNORD15A was 0.148 (0.012-1.376) in newly treated AL patients and 0.921 (0.513-2.288) in the control group, and the difference was statistically significant ( Z = -6.85, P < 0.01). The differences in SNORD15A relative expression between patients with different prognostic stratification, efficacy and with or without fever and bleeding were statistically significant (all P < 0.05). The differences in platelet count, plateletcrit and albumin levels between SNORD15A low expression group and high expression group were statistically significant (all P < 0.05), and the differences in molecular biology and cytogenetic characteristics were not statistically significant (all P > 0.05). The patients in SNORD15A high expression group had better OS than the low expression group ( P < 0.05). The results of univariate Cox regression analysis showed that SNORD15A was an influencing factor for patients' OS ( HR = 0.063, 95% CI 0.005-0.766, P < 0.05); the results of multivariate Cox regression analysis showed that fatigue ( HR = 4.754, 95% CI 1.014-22.290), fever ( HR = 0.147, 95% CI 0.029-0.746) and hemoglobin ( HR = 0.970, 95% CI 0.944 -0.998) were independent influencing factors for OS (all P < 0.05). Conclusions:SNORD15A is lowly expressed in AL and may be an indicator for disease monitoring and prognostic assessment in AL patients.

Abstract Child abuse is a global public health problem, which has emerged as a neglected yet pressing issue in global development. Early and accurate identification of abuse at a lower-age group is of great significance for treatment, which might reduce the risk of re-maltreatment and promote children s physical and mental health development. Therefore, by reviewing the clinical characteristics, risk factors and existing abuse identification and screening tools of child abuse, the study aims at providing basic evidence for the development of child abuse risk identification tools and the establishment of child maltreatment system in China, so as to take timely intervention measures to prevent adverse outcomes or reduce their severity.
