Breast cancer is a kind of malignant tumor with a complex mechanism， and its morbidity and mortality are increasing year by year， which seriously threatens women's health. At present， the main clinical treatments are surgical resection， radiotherapy， chemotherapy， and drug therapy， but they are often accompanied by side effects and adverse reactions， which affect the therapeutic effect. Traditional Chinese medicine （TCM） has the advantages of multi-component and multi-target treatment in the fight against breast cancer. The wnt/β-catenin signaling pathway is one of the classic pathways in cancer research. Abnormally activated Wnt/β-catenin signaling pathway inhibits β-catenin degradation by blocking the formation of Axin/glycogen synthase kinase 3β/adenomatous polyposis coli complex， thus promoting β-catenin nuclear metastasis， and it binds to T cell transcription factor/lymphoenhancer factor-1 to initiate downstream target genes and further interfere with the proliferation， migration， and invasion of tumor cells to affect the tumor process. Previous studies have shown that TCM monomers and compounds can mediate the Wnt/β-catenin signaling pathway to inhibit the malignant phenotype of breast cancer cells， thus playing an anti-breast cancer role， and the biochemical process involved in the regulation of therapeutic drugs has not been systematically combed. By analyzing and collating Chinese and foreign literature at the present stage， this paper discussed the association mechanism between Wnt/β-catenin signaling pathway and breast cancer and analyzed the internal mechanism of TCM monomers and compounds in mediating Wnt/β-catenin signaling pathway to exert anti-breast cancer effect. The statistical results showed that the flavonoids， alkaloids， and terpenoids in TCM monomers could target the Wnt/β-catenin signaling pathway and block the further development of malignant phenotype of breast cancer cells. TCM compounds with functions of clearing heat and detoxifying， promoting blood circulation and removing blood stasis， and tonifying kidney and liver were commonly used to intervene in the Wnt/β-catenin signaling pathway to prevent breast cancer. Compared with the current inhibitors of Wnt/β-catenin signaling pathway， the application of TCM monomers and compounds is expected to bring low-toxicity and high-efficiency breast cancer treatment drugs to the clinical practice， and the existing results provide a reference for the subsequent screening， research， and development of TCM small-molecule compounds and TCM compounds against breast cancer.

Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

[摘 要] 目的：基于公开的卵巢癌（OC）单细胞测序数据并利用生物信息学方法构建OC上皮细胞亚型，探究上皮细胞异质性及其对OC肿瘤微环境（TME）的影响。方法：使用GSE118828卵巢癌单细胞数据集的分析得到的8种细胞类型及基因表达矩阵结果，使用反卷积方法估计整体转录组测序（bulk RNA-seq）数据中的细胞组成，依据上皮细胞丰度将OC分为高上皮细胞亚型（C1型）和低上皮细胞亚型（C2型）。分析C1型与C2型患者的生存时间及免疫微环境差异。基于C1、C2型及OC早期（Ⅰ~Ⅱ期）、晚期（Ⅲ~Ⅳ期）组间的差异表达基因（DEG），筛选与OC进展相关的上皮细胞相关基因并分析其对TME的影响。通过人类蛋白质图谱（HPA）数据库数据验证OC进展中上皮细胞相关基因的蛋白表达水平。结果：C1型患者的OS明显优于C2型患者（P < 0.05）。C1、C2型具有完全不同的免疫微环境浸润特性，C1型中辅助性T（Th）细胞、M1型巨噬细胞和激活的树突状细胞浸润程度显著高于C2型（均P < 0.05）。晚期高上皮细胞OC患者HAS1、DAPL1、ADH1B基因表达增加（均P < 0.05），同时，DAPL1基因在OC中的表达与巨噬细胞、Treg细胞的浸润程度呈正相关（P < 0.05）。HPA数据库数据证实，DAPL1蛋白在OC组织中表达显著增加。结论：卵巢癌高上皮细胞亚型可能由于Th细胞、M1型巨噬细胞和激活的树突状细胞的高度浸润发挥抗肿瘤作用；上皮细胞相关基因DAPL1的高表达可能会诱导巨噬细胞、Treg细胞的浸润程度，从而促进OC的进展。

Objective: To investigate the spatio-temporal clustering characteristics of influenza in Ningxia Hui Autonomous Region from 2014 to 2023, so as to provide the basis for strengthening influenza prevention and control. Methods: Data pertaining to influenza cases reported in Ningxia Hui Autonomous Region from 2014 to 2023 were retrieved from the Infectious Disease Surveillance System of the Chinese Disease Prevention and Control Information System, including age, sex, current residence, onset date, and reporting date. The seasonal incidence of influenza was analyzed using seasonal index. The spatio-temporal clustering characteristics of influenza were identified using spatial autocorrelation analysis and spatio-temporal scan analysis. Results: A total of 20 377 influenza cases were reported in Ningxia Hui Autonomous Region from 2014 to 2023, with a male-to-female ratio of 1.15∶1. The majority were children under 15 years, with 10 950 cases accounting for 53.74%. Influenza was highly prevalent in January, February, March, and December, with seasonal indices of 219.06%, 111.00%, 246.65%, and 366.24%, respectively. The average annual reported incidence was 29.55/100 000, among which Pengyang County, Jinfeng District, Dawukou District, Xiji County, and Litong District had higher average annual reported incidence, at 63.99/100 000, 55.71/100 000, 55.70/100 000, 49.49/100 000, and 49.04/100 000, respectively. Spatial autocorrelation analysis showed that in 2023, there was spatial clustering of influenza cases in Ningxia Hui Autonomous Region (Moran's I=0.333, P<0.05), with a high-high cluster in Jingyuan County, while in other years, the distribution of influenza cases was random (all P>0.05). Spatio-temporal scan analysis showed that from 2014 to 2023, there were four space-time clusters in Ningxia Hui Autonomous Region, including one type Ⅰ cluster in Hongsibao District of Wuzhong City, with the clustering period from January 20 to 26, 2014; and three type Ⅱ clusters, mainly in January, February, March and December, covering one area in Shizuishan City, five areas in Guyuan City, one area in Zhongwei City, three areas in Wuzhong City, and four areas in Yinchuan City. Conclusions From 2014 to 2023, children under 15 years were the primary population affected by influenza in Ningxia Hui Autonomous Region, with distinct spatio-temporal distribution characteristics. The peak incidence occurred during the winter and spring seasons, and the main clustering areas were in the southern regions.

Objective: To analyze the characteristics of road traffic injuries (RTI) among urban and rural residents in Zhejiang Province, so as to provide a basis for developing targeted RTI prevention and control strategies. Methods: In April 2023, permanent residents from 13 counties (cities, districts) in Zhejiang Province were selected using a multistage stratified random sampling method. Basic information and RTI occurrences within the past 12 months were collected through questionnaire surveys. RTI incidence and characteristics of RTI among urban and rural residents were analyzed. Results: A total of 36 980 individuals were surveyed, including 18 327 males (49.56%) and 18 653 females (50.44%). The median age was 56.00 (interquartile range, 28.00) years. There were 442 person-times of RTI, with an incidence of 1.20%. The rural incidence was significantly higher than the urban (1.33% vs. 1.05%, P<0.05). The incidence of RTI increased with age and decreased with higher educational attainment (both P<0.05). The majority of RTI occurred on streets/urban areas, accounting for 59.28%. In urban, streets/urban areas were the primary locations, accounting for 76.84%. In rural, streets/urban areas and intercity highways were the main sites, accounting for 46.03% and 40.48%, respectively. There was a statistically significant difference in the composition of RTI locations between urban and rural (P<0.05). The primary treatment approach of RTI was outpatient/emergency care, accounting for 61.99%. There was a statistically significant difference in the proportion of treatment approaches of RTI between urban and rural (P<0.05). Electric bicycles were involved in 67.87% of RTI, and 54.29% of motor vehicle occupants used seat belts. No statistically significant differences were observed in the composition of transportation modes or seat belt usage rates between urban and rural (both P>0.05). The lower limb was the most commonly injured sites, accounting for 42.31%. Mild injury was predominant, accounting for 50.90%, and complete recovery was predominant outcome, accounting fo 69.68%. The median rest period was 13.50 (interquartile range, 27.25) days. The median medical expenses was 1 200.00 (interquartile range, 5 700.00) yuan. No statistically significant differences were observed between urban and rural in terms of injury sites, injury severity, outcome, rest period, or medical expenses (all P>0.05). Conclusions RTI incidence is higher among rural residents, the elderly, and lower education levels residents in Zhejiang Province. It is recommend optimizing road safety infrastructure on streets/urban areas and intercity highways, prioritizing prevention of electric bicycles RTI, strengthening safety education for high-risk population, and increasing the usage rate of safety devices.

Objective:To investigate the clinical phenotype and genetic variation of Basel-Vanagaite-Smirin-Yosef syndrome (BVSYS), and to enhance clinicians′ knowledge of the disease.Methods:The clinical data of a child with BVSYS admitted to the Department of Neurological Rehabilitation, Qingdao Women and Children′s Hospital Affiliated to Qingdao University in February 2023 were collected. Whole genome sequencing was used to analyze the pathogenic genes of the child, and Sanger sequencing was used to verify the suspected mutation sites of the family members. The clinical phenotype and genetic variation characteristics were analyzed, and the clinical characteristics of BVSYS were summarized in combination with relevant literature.Results:The patient, a female aged 3 years and 1 month, presented with global developmental delay, speech disorder, distinctive facial features, esotropia, epilepsy, hypotonia and atrial septal defect. Brain magnetic resonance imaging revealed bilateral ventriculomegaly with abnormal signal intensity in the posterior bodies of both lateral ventricles and thinning of the corpus callosum. The whole genome sequencing revealed a homozygous missense mutation c.518 (exon5) T>C (p.IIe173Thr) in the MED25 gene of the child, and Sanger sequencing confirmed that her parents and elder brother carried the aforementioned heterozygous mutation, which was classified as a likely pathogenic mutation according to the guidelines of the American College of Medical Genetics and Genomics. A total of 22 cases from 6 literature sources were retrieved, with no reported cases in China so far. Conclusions:BVSYS is clinically rare. For patients presenting with unexplained global developmental delay or intellectual disability combined with craniofacial, neurological, cardiac, and eye abnormalities, targeted genetic testing can facilitate a definite diagnosis.

Objective:To explore the impact of treatment duration with human urinary kallidinogenase (HUK) on the efficacy and safety of acute ischemic stroke (AIS).Methods:In this subgroup analysis of RESK study, a total of 990 AIS patients recruited from 65 centers in China between August 2015 and June 2020 were included and divided into short medication group (HUK for 8 days, n=185) or long medication group (HUK for 15 days or 21 days, n=805). The proportions of patients with modified Rankin Scale (mRS) score of 0, 0-1, 0-2 at 90 days, National Institutes of Health Stroke Scale (NIHSS) score change from baseline to 22 days, the proportions of patients with Barthel index (BI)≥95 at 90 days, and the incidences of adverse events were analyzed. Comparisons between groups were conducted using chi-square test, single factor and multivariate Logistic regression analysis, etc. Results:Multivariate regression analysis showed that the proportions of patients with 90-day mRS score of 0-2 [74.1% (137/185) vs 75.0% (604/805); OR=1.047, 95% CI 0.676-1.620, P=0.838] and 22-day NIHSS score change from baseline (4.60±2.00 vs 4.26±2.80; OR=-0.390, 95% CI -1.125-0.344, P=0.297) showed no statistically significant difference between the short medication and long medication groups; the proportions of patients with 90-day mRS score of 0-1 [48.1% (89/185) vs 59.1% (476/805); OR=0.674, 95%CI 0.463-0.983, P=0.041] and 90-day BI≥95 [43.6% (79/181) vs 55.1% (442/802); OR=0.614, 95%CI 0.420-0.897, P=0.012] were significantly lower in the short medication group than in the long medication group. There was no statistically significant difference in the incidences of adverse events between these 2 groups. Conclusions:In AIS patients, consecutive 8-day dosing of HUK improved immediate (22-day NIHSS score) and long-term outcome (90-day mRS score 0-2) and was safely tolerated. When applicable, extended duration of HUK could improve long-term disability-free rate (90-day mRS score 0-1) and quality of life (90-day BI) without increasing the risk of adverse events.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

Objective: To investigate the trends in incidence and mortality of prostate cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide insights into the prevention and treatment of prostate cancer. Methods: The incidence and mortality of prostate cancer among men in Huangpu District from 2002 to 2019 were collected from the Shanghai Cancer Registry System. The crude incidence, crude mortality, truncated age-standardized incidence (aged 35 to 64 years) and cumulative incidence (aged 0 to 74 years) of prostate cancer were calculated. The Chinese Fifth National Population Census in 2000 and the Segi's world standard population in 1960 were used to calculate Chinese-standardized rate and world-standardized rate. The trends in incidence and mortality of prostate cancer were evaluated using annual percent change (APC) and average annual percent change (AAPC). Results: A total of 2 672 cases of prostate cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence was 33.35/105, the Chinese-standardized incidence was 14.93/105 and the world-standardized incidence was 12.37/105 (AAPC=7.675%, 4.886% and 4.983%, all P<0.05). The incidence of prostate cancer among males at ages of 60 to <70 years and 70 to <80 years appeared increasing trends (AAPC=4.554% and 5.045%, both P<0.05). A total of 1 214 deaths of prostate cancer were reported, and the crude mortality was 15.15/105, the Chinese-standardized mortality was 6.01/105 and the world-standardized mortality was 4.61/105 (AAPC=5.500%, 2.057% and 1.784%, all P<0.05). The mortality of prostate cancer among males at ages of 80 years and above appeared an increasing trend (AAPC=4.220%, P<0.05). Conclusions The incidence and mortality of prostate cancer appeared increasing trends in Huangpu District from 2002 to 2019, and the incidence among males at ages of 60 years and above also increased. The screening for prostate cancer among males at ages of 60 years and above should be strengthened.
