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.

In the context of the modernization of traditional Chinese medicine （TCM）， the inheritance of the experiences of famous doctors faces significant challenges due to its complex nonlinear characteristics and dynamic evolution. There are still issues in the current inheritance system， such as the homogenization of talent cultivation models， lack of standardized mentoring practices， and monotonous evaluation method， which hinder the systematic inheritance and innovative development of famous doctors' experiences. Based on a systematic review of the current state of artificial intelligence （AI）-assisted inheritance of famous doctors' experiences， this study explores innovative pathways for deep integration of modern information technologies with famous doctors' experiences from key dimensions， including data authenticity assurance， interdisciplinary collaboration mechanisms， and the establishment of dynamic inheritance standards. It proposes a paradigm shift in the inheritance of TCM famous doctors' experiences in the AI era， aiming to build a new TCM inheritance system of "digital intelligence empowerment and cross-disciplinary innovation"， providing theoretical support and practical pathways for the inheritance of famous doctors' experiences in TCM.

This paper discussed the differentiation and treatment of chemotherapy-induced nausea and vomiting （CINV） in traditional Chinese medicine， based on the theory of "yin qi descends， while all yang qi ascends” from Inner Canon of Yellow Emperor （《黄帝内经》）. The core pathogenesis of CINV is attributed to chemotherapy-induced injury to the middle jiao （焦）， resulting in the separation of yin and yang and loss of their mutual communication. Acute and explosive CINV is often characterized by "all yang qi ascends"， with stomach yang constraint transforming into fire， and qi counterflow leading to vomiting， which can be treated by unblocking stomach yang， draining fire and scattering the counterflow， with Huoxiang Zhengqi Powder （藿香正气散） and medicinals of clearing function. For delayed cases， which are often due to "yin qi descends"， and the accumulation of turbid yin obstructs and constrains the deficient yang， the treatment should focus on promoting qi flow to eliminate turbidity， unblocking and boosting yang qi， and Chengqi-series Formulas （承气类方） or Xiao Banxia Decoction （小半夏汤） can be considered. Refractory and anticipated cases usually involve stomach-kidney deficiency and zang-fu （脏腑） organs disharmony， making yin and yang difficult to restore balance， for which the treatment should focus on nourishing both the stomach and kidneys and harmonize the zang-fu organs， with formulas such as Fuzi Lizhong Decoction （附子理中汤） or Xiaoyao Powder （逍遥散） modified as appropriate.

The collaborative education of ideological and political course teaching and medical humanities represents an inevitable trend in the cultivation of military medical talents. “Military doctors” are both soldiers and clinicians. The military spirit constitutes their spiritual backbone， while the medical ethics form their professional foundation. The “military” and “medical” dimensions share both unity and specificity. The professional particularity of military doctors determines that the cultivation of their humanistic literacy must be grounded in the demands of future battlefields and the developmental trends of military medicine， so as to effectively enhance their comprehensive medical support capabilities adapted to the characteristics of modern warfare. In response to the current status of humanistic educational cultivation in military medical universities， this study clarified the logical connections and value manifestations of the collaborative education between the two fields， assisted in addressing practical problems existing in the cultivation process， and explored three innovative paths. The paths encompassed integrating humanistic educational resources to promote the integrated cultivation of dual competencies in “military medicine and humanities，” innovating teaching contents and forms to improve the professional identity of military medical cadets， and reforming evaluation mechanisms to focus on the shaping and cultivation of humanistic practical abilities.

This article combined the pathogenic characteristics of "latent wind" with the theory of collateral diseases to clarify the pathological features of tumor blood vessels， including their active proliferation， high permeabi-lity， and promotion of metastasis. The theory framework of "latent wind in collaterals" as the tumor mechanism was proposed， which suggests that at the site of tumor lesions， the collaterals inherit the nature of latent wind to grow excessively， adopt an open and discharge nature to leak essence， and tumor toxins， characterized by their rapid movement and frequent changes， spread and metastasize， driving the progression of malignant tumors. Focusing on the fundamental pathogenesis of "latent wind in collaterals"， specific clinical treatment principles and methods centered on treating wind are proposed， including regulating qi and dispelling wind， clearing heat and extinguishing wind， unblocking collaterals and expelling wind， and reinforcing healthy qi to calm wind， so as to provide references for enhancing the precision of traditional Chinese medicine in treating malignant tumors.

Objective:To investigate the short-term efficacy, safety and factors affecting recurrence of intermediate-risk and high-risk non-muscle invasive bladder cancer (NMIBC) treated with intravesical instillation of domestic Bacillus Calmette-Guérin (BCG) infusion.Methods:This study was a retrospective cohort study. We collected the data of 163 patients with NMIBC treated with domestic BCG after transurethral resection of bladder tumor (TURBT) from October 2016 to October 2020 in the Department of Urology, the Affiliated Hospital of Qingdao University. There were 140 males and 23 females, the age was(67.3±10.3) years old. 23 cases had only been received BCG and 140 cases received other chemotherapy drugs before. The induction scheme of instillation was started after the TURBT at once a week for 6 consecutive weeks, continue instillation at every two weeks for 3 doses, then maintenance instillation once a month for 10 consecutive times, for a total of 19 instillations. Kaplan-Meier analysis was used to calculate recurrence-free survival. Binary Logistic regression was used to analyze factors and stepwise regression (backward method) was employed to identify independent risk factors for recurrence after BCG instillation. The incidence of adverse reactions was recorded. Measurement data with normal distribution were expressed as mean±standard deviation( ± s), measurement data with skewed distribution were expressed as M( Q1, Q3), and count data were expressed as frequency and percentage(%). Results:A total of 23 cases experienced recurrence within the 13-month of instillation, of which 7 cases were found to have progressed by pathological biopsy, and the cumulative recurrence-free rate was 85.9%. The results of binary logistic regression analysis showed that the history of re-TURBT ( P=0.010) was an independent predictor for recurrence after BCG intravesical instillation. Adverse events occurred in 110 cases. The main symptoms of the 65 cases were urgency of urination, pollakiuria and dysuria with urinary irritation, urinary tract infection in 15 cases, hematuria in 10 cases, and other symptoms in 20 cases. Instillation was terminated in 7 cases due to side effects, no serious adverse events such as spread of tuberculous bacteria were observed in the cases. Conclusions:Patients with NMIBC treated with intravesical instillation of domestic BCG have significant short-term efficacy, while patients who have previously received re-TURBT is an independent predictor for recurrence. The domestic BCG have the characteristic of slight side effect, good efficacy and safety.

AIM To explore the effects of Dahuang Lingxian Recipe on Th1/Th2 cell immune imbalance in a rat model of cholestatic liver fibrosis(CLF).METHODS 20 SD rats were randomly divided into the normal group,the model group,the ursodeoxycholic acid group(0.063 g/kg)and the Dahuang Lingxian Recipe group(4.8 g/kg),with 5 rats in each group.Except for those of the normal group,the rats of all other groups had open surgery of common bile duct ligation,followed by the gavage of corresponding drug two days later,and the procurement of the samples after gavage in the third week.The rats had their degree of liver fibrosis observed by HE and Masson stainings;their levels of serum total bile acid(TBA),alkaline phosphatase(AKP),γ-glutamyltransferase(γ-GT),alanine aminotransferase(ALT),aspartate aminotransferase(AST)and total bilirubin(TBil)measured by the kit;their hepatic percentage of TGF-β1,p-Smad2 and p-Smad3 positive cells detected by immunofluorescence and immunohistochemical staining;their.hepatic expressions of TGF-β1,Smad4,NF-κB p65,Collagen Ⅰ and Collagen Ⅲ protein and mRNA detected by Western blot and RT-qPCR;their levels of helper T cell 1(Th1)and helper T cell 2(Th2)in peripheral blood detected by flow cytometry,and their ratio of Th1/Th2 calculated as well.RESULTS Compared with the model group,the groups intervened with either ursodeoxycholic acid or Dahuang Lingxian Recipe displayed well-ordered liver cells,hepatic lobules and hepatic cords;a small amount of fatty degeneration;significantly reduced connective hyperplasia of hepatic fibers;significantly narrowed fibrous cords;a small amount of blue fibrous septa;greatly improved pathological injuries including inflammatory infiltration of central vein and portal area;decreased levels of serum TBA,TBil,AKP,γ-GT,ALT and AST(P＜0.05);decreased hepatic expressions of TGF-β1,p-Smad2 and p-Smad3(P＜0.05);decreased hepatic expressions of TGF-β1,Smad4,NF-κB p65,Collagen Ⅰ and Collagen Ⅲ protein and mRNA(P＜0.05);and increased counts of Th1 cells in peripheral blood,decreased counts of Th2 cells,resultsing increased Th1/Th2 ratio(P＜0.05).And an even better effect was observed in the Dahuang Lingxian Recipe group.CONCLUSION Dahuang Lingxian Recipe can reduce or reverse CLF by inhibiting hepatic stellate cell activation through maintaining Th1/Th2 cell immune balance via the NF-κB/TGF-β1 signaling pathway.

Epigenetic modifications of RNA play a crucial role in the initiation and progression of tumors.Among these modifications,N6-methyladenosine(m6A)modification catalyzed by the METTL3 methyltransferase is one of the most common RNA modifications.It is essential for regulating RNA transcription,stability,and translation.At the same time,long non-coding RNAs(lncRNAs)also serve as important regulatory molecules and play a significant role in the development and progression of tumors.However,the reciprocal interaction between lncRNAs and METTL3,as well as their functional mechanisms within tumors,are not fully understood.This paper aims to provide a comprehensive over-view of the mutual regulation between lncRNAs and METTL3 in tumors.The goal is to offer new insights and theoretical foundations for a better understanding of tumor pathogenesis.

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.
