Background::Breast cancer is ranked among the most prevalent malignancies in the Chinese female population. However, comprehensive reports detailing the latest epidemiological data and attributable disease burden have not been extensively documented.Methods::In 2018, high-quality cancer surveillance data were recorded in 700 population-based cancer registries in China. We extracted data on female breast cancers (International Classification of Diseases, Tenth Revision [ICD-10]: C50) and estimated the incidence and mortality in 2022 according to the baseline data and corresponding trends from 2010 to 2018. Pathological types were classified according to the ICD for Oncology, 3rd Edition codes. Disability-adjusted life years (DALYs) were calculated as the sum of the years of life lost (YLLs) and years lived with disability (YLDs).Results::In 2022, approximately 357,200 new female breast cancer cases and 75,000 deaths occurred in China, accounting for 15.59% and 7.94% of total new cancer cases and deaths, respectively. The age-standardized incidence rate (ASIR) was 33.04 per 100,000. When analyzed by pathological type, the ASIRs for papillary neoplasms, invasive breast carcinoma, rare and salivary gland-type tumors, and other types were 1.13, 29.79, 0.24, and 1.88 per 100,000, respectively. The age-standardized mortality rate (ASMR) was 6.10 per 100,000. A total of 2,628,000 DALYs were found to be attributable to female breast cancer in China, comprising 2,278,300 YLLs and 349,700 YLDs. The ASIR, ASMR, and age-standardized rate (ASR) for DALYs in urban areas were consistently higher than those in rural areas. We observed a four-fold increase in the ASIR and ASR for DALYs and an eight-fold increase in the ASMR among females over 55 years compared with those aged under 55 years.Conclusion::These data provide invaluable insights into the latest epidemiology of female breast cancer in China and highlight the urgency for disease prevention and control strategy formulation.

BackgroundHome-based intervention occupies a prominent place in the treatment of autism spectrum disorder （ASD） in children， whereas previous studies on the effect of home-based early intensive behavioral intervention on verbal ability of children with ASD are somewhat inadequate. ObjectiveTo study the effects of intensive family behavioral of intervention based on Verbal Behavior Milestones Assessment and Placement Program （VB-MAPP） on the language ability of children with ASD， so as to provide references for the development of family intervention strategies for children with ASD. MethodsChildren aged 2 to 3 years old who attended the Children's Rehabilitation Department of the Second Affiliated Hospital of Shantou University Medical College from September 2020 to December 2021 and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria for ASD were selected as the study objects. A non-randomized concurrent control trial was conducted to compare a study group （n=24） receiving home-based early intensive behavioral intervention using VB-MAPP with a control group （n=14） receiving training from other special institutions or early childhood education institutions. The intervention lasted for 6 months in both groups. Before and after the intervention， the VB-MAPP milestone assessment was performed in the two groups， and the VB-MAPP milestone score， mand， trac and listener responds were selected as the study indicators. Then the intervention effect was compared between two groups， and the multiple linear regression was performed to screen the related influencing factors. ResultsAfter intervention， the total milestone assessment score， mand， tact and listener responds scores of study group were higher than those of control group， with statistical difference （Z=-4.339~-2.195， P<0.05 or 0.01）. Multiple linear regression analysis denoted that the average weekly hours of home-based intervention in the first three months had certain effect on listener responds （β=1.029， P<0.05）. ConclusionApplication of home-based early intensive behavior intervention using VB-MAPP may contribute to the improvement of verbal abilities such as mand， tact and listener responds in children with ASD. ［Funded by 2020 Guangdong Provincial Science and Technology Innovation Strategy Special Fund （number， 20200601）］

High-quality hospital development calls for high-quality hospital culture.Hospital culture is the core of hospi-tal management,which deeply affects the development direction and operation mode of the hospital,throughout the whole process of high-quality development of the hospital,but also an indispensable component of social culture.This paper discusses and con-siders the definition and value of hospital culture,the dilemma of the ideological level and management level of hospital culture construction,and countermeasures,which provides a reference for hospital management and promotes the high-quality develop-ment of hospitals.

Exposure to particulate matter 2.5 (PM2.5) potentially triggers airway inflammation by activating nuclear factor-κB (NF-κB). Sirtuin 2 (SIRT2) is a key modulator in inflammation. However, the function and specific mechanisms of SIRT2 in PM2.5-induced airway inflammation are largely understudied. Therefore, this work investigated the mechanisms of SIRT2 in regulating the phosphorylation and acetylation of p65 influenced by PM2.5-induced airway inflammation and bronchial hyperresponsiveness. Results revealed that PM2.5 exposure lowered the expression and activity of SIRT2 in bronchial tissues. Subsequently, SIRT2 impairment promoted the phosphorylation and acetylation of p65 and activated the NF-κB signaling pathway. The activation of p65 triggered airway inflammation, increment of mucus secretion by goblet cells, and acceleration of tracheal stenosis. Meanwhile, p65 phosphorylation and acetylation, airway inflammation, and bronchial hyperresponsiveness were deteriorated in SIRT2 knockout mice exposed to PM2.5. Triptolide (a specific p65 inhibitor) reversed p65 activation and ameliorated PM2.5-induced airway inflammation and bronchial hyperresponsiveness. Our findings provide novel insights into the molecular mechanisms underlying the toxicity of PM2.5 exposure. Triptolide inhibition of p65 phosphorylation and acetylation could be an effective therapeutic approach in averting PM2.5-induced airway inflammation and bronchial hyperresponsiveness.

Objective:To investigate the clinical efficacy and safety of ibrutinib in treatment of chronic lymphocytic leukemia (CLL).Methods:The clinical data of 68 patients with CLL in Fujian Medical University Union Hospital from May 1998 to October 2019 were retrospectively analyzed, including 39 cases receiving ibrutinib as the first therapy, 20 cases receiving ibrutinib as the second therapy, and 9 cases receiving ibrutinib as the second and above therapy. The clinical characteristics, IGHV gene mutation, the short-term therapeutic efficacy and survival of patients with stratified chromosomal karyotype were analyzed; the adverse events were also analyzed.Results:The median follow-up time was 53.2 months until May 2020. The objective remission rate (ORR) was 83.8% (57/68), including 8 cases (11.8%) of complete remission, 49 cases (72.1%) of partial remission, 5 cases (7.4%) of the stable disease, 6 cases (8.8%) of progression of the disease. The ORR of patients without IGHVmutation was higher than that of those with IGHV mutation [93.3% (28/30) vs. 76.3% (29/38), χ2=33.656, P<0.05]; the ORR of patients with low risk and low-moderate risk International Prognostic Index (IPI) score was higher than that of those with moderate-high risk and high risk [90.6% (29/32) vs. 77.8% (28/36), χ2=7.248, P = 0.007], and differences in the ORR of patients stratified by other factors were not statistically significant (all P > 0.05). Among 68 patients, 31 cases (45.6%) had adverse reactions and they insistently received the treatment; 26 cases (38.2%) had grade1-2 adverse reactions, 5 cases (7.4%) had grade 3 and above adverse reactions; 2 cases (2.9%) had drug withdrawal because of adverse reactions. The median progression-free survival (PFS) time and overall survival (OS) time of CLL patients treated with ibrutinib had not been reached. The 5-year PFS rate of patients with IGHV mutation was higher than that of patients with IGHV non-mutation (100.0% vs.72.1%, P = 0.020), the 5-year PFS rate of patients with normal chromosome karyotype was higher than that of those with abnormal chromosome karyotype (100.0% vs.74.3%, P = 0.019). Conclusion:Ibrutinib is effective and safe in treatment of CLL patients.

Objective: To understand the changes of serum transient receptor potential channel 1(TRPC1) in patients with vascular depression. Methods: 58 patients with vascular depression, 49 patients with major depressive disorder and 38 healthy controls were recruited.The TRPC1 of all subjects were detected by ELISA.Patients with vascular depression and patients with primary depression were scaled by HAMD-17.The level of TRPC1 was contrasted in different ages groups and in different nosogenesis (cerebral infarction, ischemic cerebrovascular disease, old cerebral hemorrhage, cerebral microbleeds, vascular risk factors, etc.) of vascular depression.The relationship between TRPC1 level and severity of depressive symptoms was further analyzed. Results: (1)The level of TRPC1 of serum((643.76±118.43)pg/ml) was decreased in patients with vascular depression compared with that in healthy controls ((712.48± 98.75) pg/ml). The level of TRPC1 in patients with vascular depression over 60 years ((601.43±113.55)pg/ml)was lower than that in patients with major depressive disorder over 60 years ((626.32±125.46)pg/ml) and healthy controls over 60 years((721.84± 99.62)pg/ml) .(2) Among the various causes of vascular depression, the level of TRPC1 in patients with cerebral infarction, ischemic cerebrovascular disease and cerebral microbleeds was significantly lower (P<0.05). (3) The levels of TRPC1 in the patients with vascular depression (r=-0.962, P<0.05) and patients with major depressive disorder (r=-0.674, P<0.05) were negatively correlated with HAMD-17 score. Conclusion The level of TRPC1 is lower in patients with vascular depression, which is more obvious in patients with cerebral infarction, ischemic cerebrovascular disease, and cerebral microhaemorrhage.The lower the level of TRPC1, the more severe the depression.The neuroprotective effect of TRPC1 is reduced in patients with vascular depression.The TRPC1 can be used as a biomarker for vascular depression.

Objective To explore the potential mechanisms of mesenchymal stem cell (MSC) therapy in ischemia/reperfusion injury (IRI)-induced acute kidney injury (AKI). Methods Forty-five C57/BL6 male mice were randomly divided into three groups: sham group, IRI group, and IRI+MSCs group, with 15 mice in each group. The IRI-induced AKI model in mice was reproduced by clamping both renal pedicles for 35 minutes. In the sham group, both kidneys were exposed, but their pedicles were not clamped. Six hours after reperfusion, mice in IRI+MSCs group received 100 μL of MSCs (1×104 /μL) isolated from the bone marrow from C57/BL6 mice via tail vein, while the mice in the IRI group received same amount of normal saline. Blood samples were harvested at 48 hours after reperfusion, and levels of serum creatinine (SCr) and blood urea nitrogen (BUN) were determined. The changes in renal pathology were observed by microscopy with PAS staining, and the tubular injury and acute tubular necrosis (ATN) scores were calculated. The number of leukocytes (CD45+) infiltrated in kidney at 24 hours and 72 hours after reperfusion was measured with flow cytometry. The number of neutrophils (Ly-6G+) and macrophages (F4/80+) infiltrated in kidneys at 24 hours and 72 hours after reperfusion was determined by immunofluorescence. Results There was significant increase in the related parameters in IRI group compared with those of sham group. The levels of SCr (μmol/L) and BUN (mmol/L) were 180.3±8.8 vs. 9.7±3.5, and 1 121.1±8.3 vs. 9.4±2.3, both P < 0.01. The score of tubular injury was 4.80±0.55 vs. 0 at 48 hours after reperfusion. The quantity of leukocyte (CD45+) infiltration in kidney at 24 hours and 72 hours after reperfusion was increased (×105 cells/g: 60.50±2.56 vs. 19.46±4.83, 42.00±1.87 vs. 14.70±3.74, both P < 0.01), and the number of neutrophils (Ly-6G+) and macrophages (F4/80+) infiltrated in kidney at 24 hours and 72 hours after reperfusion was also increase although the number of leukocytes infiltrated in kidney was significantly lower at 72 hours after reperfusion than that at 24 hours. There was significant lowering of the levels of SCr and BUN [SCr (μmol/L): 99.0±8.0 vs. 180.3±8.8, BUN (mmol/L): 84.5±7.6 vs. 112.1±8.3, both P < 0.01] in IRI+MSCs group, compared to IRI group. For the degree of tubular necrosis in two groups, the tubular injury scores were 2.60±0.55 vs. 4.80±0.55 (P < 0.05). The number of leukocytes infiltrated in kidney at 24 hours and 72 hours after reperfusion (×105 cells/g) were 24.20±4.53 vs. 60.50±2.56, 31.70±3.15 vs. 42.00±1.87 (both P < 0.01). The number of neutrophils was lowered despite (the number of macrophages was increased). However, the number of infiltrated leukocytes was significantly more in IRI+MSCs group at 72 hours than that at 24 hours (×105 cells/g: 31.70±3.15 vs. 24.20±4.53, P < 0.05). Conclusion MSCs could protect against IRI induced AKI by reducing the total number of leuckocytes, especially that of the neutrophils infiltrating into ischemic kidney and by recruiting macrophages into ischemic kidney.

Objective: To study the serum interleukin-37 (IL-37) level changes in patients with acute coronary syndrome (ACS) and to explore the relationship between IL-37 and coronary atherosclerotic plaque.
Methods: Our research included 3 groups. ACS group, n=60, SAP (stable angina pectoris) group, n=30 and Control group, the subjects with normal coronary artery, n=15. The peripheral serum levels of IL-37 were examined by ELISA and the differences were compared among different groups.
Results: ① The serum levels of IL-37 at admission were as ACS group < SAP group < Control group, P<0.05.②Intervention could transitionally decrease IL-37 level in SAP group. With 4 weeks treatment, IL-37 levels were signiifcantly increased in both ACS group and SAP group than admission time, while they were still lower than Control group, P<0.05.③The serum level of IL-37 at admission was negatively related to IL-18 (r=-0.79, P<0.05), the ratio of IL-18/IL-37 were as ACS group>SAP group>Control group, P<0.05.④In ACS group, IL-37 level was negatively related to GRACE score (r=-0.71, P<0.05), the ratio of IL-18/IL-37 was positively related to GRACE score (r=0.73, P<0.05).⑤The diagnosis of ACS could be basically excluded if the patients with IL-37>77ug/L.
Conclusion: The serum IL-37 might be involved in the inlfammatory process in ACS patients, it could be expected as an index for ACS monitor and evaluation in clinical practice.
