ObjectiveTo investigate the characteristics of gray matter structure and clinical symptoms in patients with Alzheimer's disease （AD） comorbid with apathy （AD-A）. MethodsThe study included 30 patients with AD-A， 30 AD disease patients without apathy （AD without apathy， AD-NA）， and 30 healthy controls （HCs） matched in gender， age， and years of education. All participants underwent a comprehensive neuropsychological assessment and magnetic resonance imaging （MRI） scans. Voxel-based morphometry （VBM） was used to analyze changes in gray matter volume among the three groups. Additionally， the correlation between the identified abnormal brain regions and apathy scale scores was analyzed. ResultsThere were no statistically significant differences among the three groups in terms of age， gender， years of education， or total intracranial volume. Compared with the HCs group， both the AD-A and AD-NA groups showed significantly lower scores in cognitive function （P<0.001）. The AD-A group exhibited significantly higher apathy scale scores compared with the AD-NA group （P<0.001）. Compared with the AD-NA group， the AD-A group showed reduced gray matter volume in the bilateral caudate nucleus， left orbitofrontal cortex， lingual gyrus， inferior frontal gyrus， superior frontal gyrus， entorhinal cortex， right middle frontal gyrus and posterior cingulate cortex （FWE-corrected， P<0.05 for all）. Compared with the HCs group， the AD-A group exhibited reduced gray matter volume in the bilateral middle temporal gyrus， left fusiform gyrus， calcarine sulcus， postcentral gyrus， right inferior frontal gyrus and supramarginal gyrus （FWE-corrected， P<0.05 for all）. Compared with the HCs group， the AD-NA group showed reduced gray matter volume in the left precuneus， inferior temporal gyrus， and right inferior temporal gyrus （FWE-corrected， P<0.05 for all）. In the AD-A group， changes in the gray matter volume of the left caudate nucleus （r= -0.557， P=0.002） and right middle frontal gyrus （r=-0.620， P=0.001） were negatively correlated with the apathy evaluation scale （AES） scores. ConclusionPatients in the AD-A group exhibited significant atrophy in the frontal-temporal-basal ganglia circuit， and the degree of gray matter atrophy was correlated with the severity of apathy.

During the period of the Republic of China, acupuncture faced different opportunities and developments in China and the West. The correspondence between Soulié de Morant, the father of European acupuncture, and FANG Shen'an, a famous acupuncture master of the Republic of China, is of great significance to explore the exchange of acupuncture between China and France, the development of acupuncture in France, the Western learning of Chinese medicine, and the dissemination of academic ideas of acupuncture in the Republic of China. The authors studied Soulié de Morant's collection stored in the Museum of Western Studies of Chinese Medicine of Yunnan University of Chinese Medicine, and found Soulié de Morant's annotation of Jinzhen Mizhuan (Secrets of Golden Needle), the 1937 edition, and 3 paper letters with FANG Shen'an (2 letters in French and 1 letter in Chinese). After the language translation and collation, based on the correspondence between two masters, in association with the historical background and the narration of CHEN Yemeng, the inheritor of Fang's acupuncture, this paper reviews the process of academic exchanges between them, so as to display the historical development of acupuncture in China and the West.

In 1929, George Soulié de Morant and Paul Ferreyrolles co-authored their first acupuncture-moxibustion paper titled "L' Acuponcture en Chine vingt siècles avant J.-C. et la réflexothérapie moderne", greatly advancing the development of acupuncture-moxibustion in Europe. Their paper systematically explains the holistic view and the concept of yin-yang balance in traditional Chinese medicine, describes the techniques of acupuncture and moxibustion, innovatively classifies acupuncture-moxibustion as "reflexotherapy", organizes the effects of certain acupuncture points illustrated on human acupoint atlas; and for the first time, it summarizes the correspondence between acupuncture points and Weihe trigger points. In the historical background of the neo-Hippocratic movement, they used the existing theories at that time to explain acupuncture, and adopted the analogical medicine to explore the mechanisms of acupuncture-moxibustion, which gradually initiated the modern era of acupuncture-moxibustion in France. Such research method is conducive to reducing the unfamiliarity of acupuncture-moxibustion among westerners, deepening their understanding of its theories and therapeutic effect, and also integrating it with other medical research. It breaks through the limitations of traditional theories and obtains the self-improvement and progress.

During the mid-20th century, Dr. Paul Ferreyrolles played an important role in the dissemination of acupuncture in France. He keenly recognized the unique value of the acupuncture knowledge brought from China by Soulié de Morant, devoted himself to its practice and research, and attempted to interpret its principles through western knowledge. From Ferreyrolles' experiences and contributions, three key factors can be identified for the successful spread of acupuncture in Europe: the availability of comprehensive translated texts, the broad recognition of therapeutic efficacy, and the adaptation and interpretation of acupuncture in western terms.

BACKGROUND: Neoadjuvant chemoradiotherapy followed by radical surgery has been a common practice for patients with locally advanced rectal cancer, but the response rate varies among patients. This study aimed to develop a ResNet-Vision Transformer based magnetic resonance imaging (MRI)-endoscopy fusion model to precisely predict treatment response and provide personalized treatment. METHODS: In this multicenter study, 366 eligible patients who had undergone neoadjuvant chemoradiotherapy followed by radical surgery at eight Chinese tertiary hospitals between January 2017 and June 2024 were recruited, with 2928 pretreatment colonic endoscopic images and 366 pelvic MRI images. An MRI-endoscopy fusion model was constructed based on the ResNet backbone and Transformer network using pretreatment MRI and endoscopic images. Treatment response was defined as good response or non-good response based on the tumor regression grade. The Delong test and the Hanley-McNeil test were utilized to compare prediction performance among different models and different subgroups, respectively. The predictive performance of the MRI-endoscopy fusion model was comprehensively validated in the test sets and was further compared to that of the single-modal MRI model and single-modal endoscopy model. RESULTS: The MRI-endoscopy fusion model demonstrated favorable prediction performance. In the internal validation set, the area under the curve (AUC) and accuracy were 0.852 (95% confidence interval [CI]: 0.744-0.940) and 0.737 (95% CI: 0.712-0.844), respectively. Moreover, the AUC and accuracy reached 0.769 (95% CI: 0.678-0.861) and 0.729 (95% CI: 0.628-0.821), respectively, in the external test set. In addition, the MRI-endoscopy fusion model outperformed the single-modal MRI model (AUC: 0.692 [95% CI: 0.609-0.783], accuracy: 0.659 [95% CI: 0.565-0.775]) and the single-modal endoscopy model (AUC: 0.720 [95% CI: 0.617-0.823], accuracy: 0.713 [95% CI: 0.612-0.809]) in the external test set. CONCLUSION The MRI-endoscopy fusion model based on ResNet-Vision Transformer achieved favorable performance in predicting treatment response to neoadjuvant chemoradiotherapy and holds tremendous potential for enabling personalized treatment regimens for locally advanced rectal cancer patients.

Background and purpose:The Shanghai Municipal Center for Disease Control and Prevention provides annual updates on cancer statistics in Shanghai.Breast cancer is one of the common malignant tumors among women.In recent years,the incidence of female breast cancer was increasing,while its trend of mortality showed declining.This study aimed to investigate the survival rates of new female breast cancer cases in Shanghai from 2002 to 2017.Methods:Data of new cases and deaths of female breast cancer patients with follow-up information from 2002 to 2017 were obtained from the Population-based Cancer Registry and Vital Statistics System of Shanghai Municipal Center for Disease Control and Prevention.Numbers,proportions,and survival rates were stratified by year of diagnosis,age,histological type and stage at diagnosis for analysis.The 5-year observed survival rates were calculated based on the life table method.The probabilities of surviving from 0 to 99 years were estimated with the Elandt-Johnson model,and then cumulative expected survival rates were calculated using the Ederer Ⅱ method.Finally,the 5-year relative survival rates were calculated.The annual percent change(APC)of survival rates was estimated by Joinpoint Regression Program.Results:A total of 73 600 new female breast cancer cases were diagnosed from 2002 to 2017 in Shanghai.Among them,67 681 cases were morphological verification,accounting for 91.96%.By December 31,2022,23 745(32.26%)cases had died,and 19 466(26.45%)cases had died of cancer.A total of 68 332(92.84%)cases,who were either dead or followed for over 5 years,were considered to have complete follow-up.The remaining 5 268(7.16%)cases were lost to follow-up.73 538(99.92%)cases were included in the observed cohort for survival analysis.The number of observed cases nearly doubled from 3330 in 2002 to 6095 in 2017.The 5-year observed survival rate changed from 78.77%in 2002 to 84.55%in 2017 dynamically,showed a low increasing trend with an average rate of 0.50%per year(APC=0.50%,t=8.75,P＜0.001).The 5-year relative survival rate also increased from 83.46%to 89.24%slowly,with an average rate of 0.47%(APC=0.47%,t=9.80,P＜0.001).The overall 5-year observation survival rate of female cancer was 83.24%(82.96%-83.52%),and the 5-year relative survival rate was 87.58%(87.29%-87.87%)in Shanghai from 2002 to 2017.It was increasing over time,decreasing with aging and advanced stage at diagnosis continuously.There was no significant difference in the 5-year relative survival rates between the groups aged 15 to 64(P＞0.05).The group with an unknown stage had the highest number of cases,followed by the stage Ⅱ group,and then the stage Ⅰ group.The 5-year relative survival rate of cases with stage Ⅰ disease reached 99.10%(98.78%-99.42%),but these cases only accounted for 25.51%of the total.The 5-year relative survival rate of cases with stage Ⅳ disease was 52.54%(50.98%-54.11%),and these cases accounted for 6.13%of the total.The 5-year relative survival rate of cases with s unknown stage was 82.04%(81.42%-82.65%),and these cases accounted for 31.05%of the total.Conclusion:The diagnostic levels and survival rates of female breast cancer in Shanghai were relatively high and continue to improve.However,the proportions of cases with unknown histological type and unknown stage remain relatively high,and the proportion of stage Ⅰ cases is not very large.The survival rates of stage Ⅳ cases are relatively low.This study provides evidence for further research,prevention and control efforts for female breast cancer.

This study retrospectively analyzed the clinical data of 43 patients with large-volume renal calculi treated with flexible ureteroscopic lithotripsy (FURL)at our hospital from August 2020 to August 2023. Among the patients, 26 were male and 17 were female; 22 had left-sided stones and 21 had right-sided stones. Thirty-three patients had preoperative placement of a double-J (D-J)stent, while 10 did not. The mean age was (42.7±11.1)years, the mean stone volume was (10.3±3.5)cm 3, and the mean operative time was (97.9±10.4)minutes. All procedures were completed using reusable flexible ureteroscopic lithotripsy. Twenty-two patients received traditional methods of stone expulsion after FURL (control group), while 21 patients received a combination of traditional methods and extracorporeal physical vibration lithotripsy (EPVL) after FURL (experimental group). The experimental group showed a significantly higher stone-free rate at one month (85.7% vs. 54.5%)and a lower reoperation rate (4.8% vs. 31.8%)compared to the control group. The difference in reoperation rates between the experimental and control groups was statistically significant ( P< 0.05). These results suggest that the combination of reusable ureteroscopic lithotripsy and EPVL is a feasible treatment option for large-volume renal calculi.

Background and purpose:The colorectal cancer screening program for community residents in Shanghai has been implemented for 12 years since 2013.This study aimed to analyze the impact of screening on the colorectal cancer incidence,stage and survival outcomes based on their screening participation status.Methods:This study used registry-based cohort study method.The registered residents in Shanghai from 2013 to 2017 who met the screening age range were divided into screening group and non-screening group.The data of colorectal cancer cases after being included in groups were obtained from the Population Based Cancer Registry.We calculated age-standardized cumulative incidence and age-group cumulative incidence,diagnosis stage and survival rate of colorectal cancer by gender,age and year of diagnosis.We used the Joinpoint regression method to calculate the annual change percentage for cumulative incidence trend analysis.The life table method and EdererⅡ method were used to calculate the 5-year observed survival rates and expected survival rates of colorectal cancer cases.Finally the 5-year relative survival rates were obtained.Results:The study included 1 687 689 participants aged 50-74 in screening group and 4 713 307 participants in non-screening group.During a 5-year follow-up period,there were 10 333 and 20 904 new cases of colorectal cancer diagnosed in the two groups,respectively.The age-standardized 5-year cumulative incidence in the screening group was 555.33/105,with an average annual increase of 33.32%(P＜0.05).The age-standardized 5-year cumulative incidence in the non-screening group was 529.85/105,with an average annual increase of 48.13%(P＜0.05).There was no statistically significant difference between the screening group and the non-screening group in the age-standardized 5-year cumulative incidence(X=0.25,P=0.804).The lower the age group,the greater the difference between the screening group and the non-screening group in the annual average change percentage of the age-standardized cumulative incidence.The stages 0-Ⅰ of newly diagnosed colorectal cancer cases in the screening group and non-screening group accounted for 14.70%and 7.46%,respectively,with a statistically significant difference in composition between the two groups(P＜0.05).The 5-year relative survival rate of the screening group was 73.94%,while the non-screening group was 59.66%.The survival rate indicators of the former were significantly higher than those of the latter,and the difference was statistically significant.The survival rate of the former was significantly higher than that of the latter(73.94%vs 59.66%),and the difference was statistically significant(P＜0.05).The survival rate of females in both groups of cases was higher than that of males,and the survival rate decreased with increasing age-groups at diagnosis.Conclusion:With the implementation of the colorectal cancer screening program,the growth trend of the incidence rate of colorectal cancer among the screening participants has been curbed,and the early stages of colorectal cancer cases diagnosed and the 5-year survival rate were significantly improved.In order to reduce the incidence rate of colorectal cancer in the whole population,it is necessary to vigorously promote the screening coverage of the appropriate population,especially to increase the proportion of lower age groups participating in screening.We should also pay attention to the screening quality of the elderly groups and improve the compliance of colonoscopy in high-risk participants.At the same time,we should further optimize the refined management of screening for different genders,ages,and risk groups.

Alzheimer′s disease is a serious neurodegenerative disorder. Approximately 80% to 90% of patients are accompanied by behavioral and psychological symptoms of dementia (BPSD), which manifest as a series of behavioral, psychological and mental abnormalities. These abnormalities can accelerate the cognitive deterioration and premature death of patients, and thus are regarded as important clinical symptoms. However, the pathogenesis of BPSD is still unknown, and treatment methods are limited. The pathogenesis of BPSD from the perspective of neuroimaging and pathophysiology, and possible treatment measures were analyzed in this article, in order to provide references for the early diagnosis and treatment of BPSD.
