Xiao Chaihutang， originating from the Treatise on Typhoid and Miscellaneous Diseases， is a classic formula for harmonizing the Shaoyang. It excels in regulating the pivotal mechanism and unblocking the triple energizer， corresponding to the pathogenesis of digestive system tumors characterized by the interlocking of deficiency， stasis， phlegm， and toxicity， as well as disharmony between Yin and Yang. This paper systematically reviews research findings from China and abroad over the past decade， exploring the anti-tumor effects of Xiao Chaihutang on digestive system tumors from three dimensions： theoretical rationale， clinical efficacy， and molecular mechanisms. At the level of principle and method， Xiao Chaihutang takes "harmonization" as its core therapeutic guideline. By reconciling the exterior and interior to restore the Shaoyang pivot， harmonizing Yin and Yang to improve the tumor microenvironment， and regulating the liver and spleen to consolidate and protect the foundation of postnatal essence， it promotes the restoration of the body's dynamic balance of Yin and Yang. Clinical studies have demonstrated that Xiao Chaihutang， used alone or in combination with modern medical therapies， shows definite efficacy against digestive system tumors such as hepatocellular carcinoma， pancreatic carcinoma， and gastrointestinal carcinoma. It can significantly improve patients' quality of life， inhibit tumor progression， effectively relieve concomitant symptoms such a s cancer-related fever， anxiety， depression， and insomnia， and alleviate postoperative embolic syndromes as well as adverse reactions to radiotherapy and chemotherapy. Experimental studies have revealed that Xiao Chaihutang can inhibit tumor cell proliferation， induce apoptosis， arrest the cell cycle， suppress tumor cell invasion and metastasis， and improve the tumor microenvironment. Through the above analysis， this study elucidates the current clinical and experimental research status of Xiao Chaihutang in the treatment of digestive system tumors， aiming to provide theoretical support for its precise clinical application. On this basis， it further explores key issues in the identification of pharmacodynamic substances and the accumulation of evidence in evidence-based medicine， thereby offering a new perspective for the innovative development of integrative Chinese and Western medicine in synergistic cancer therapy.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To investigate the effects of peroxisome proliferator activated receptor-gamma(PPARγ)gene silen-cing in human bone marrow stromal cells(HS-5)on hematopoietic function in bone marrow-suppressed mice,and to explore the potential mechanisms involved.Methods A bone marrow-suppressed mouse model was established by whole-body X-ray irradi-ation.Two hours after modeling,the mice were randomly divided into three groups:experimental group(intravenous injection of PPARγ RNAi-interfered HS-5 cells through the tail vein),control group(intravenous injection of PPARγ RNAi-uninterfered HS-5 cells through the tail vein),and blank group(intravenous injection of an equal amount of saline through the tail vein),with 5 mice in each group.Peripheral blood routine tests were performed before,24 hours after,1 week after,and 2 weeks after radio-therapy.In vitro osteogenic and adipogenic induction was performed in cells,and the cells were divided into experimental group(PPARγ RNAi-interfered HS-5 cells),control group(PPARγ-uninterfered HS-5 cells),and blank group(HS-5 cells without os-teogenic/adipogenic induction).Osteogenic/adipogenic staining was observed.The effects of PPARγ gene-silenced HS-5 cells on mouse bone marrow hematopoietic stem cells(HSCs)were detected by CCK-8 proliferation assay.The groups included experi-mental group(PPARγ RNAi-interfered HS-5 cells were co-cultured with mouse HSCs after 3 days of osteogenic induction dif-ferentiation),positive control group(HS-5 cells treated with 50 μmol/L PPARγ inhibitor were co-cultured with mouse HSCs af-ter 3 days of osteogenic induction differentiation),negative control group(PPARγ RNAi-uninterfered HS-5 cells were co-cul-tured with mouse HSCs after 3 days of osteogenic induction differentiation),and blank group(Mouse HSCs were cultured alone without co-culturing with HS-5 cells).Results After radiotherapy,the hematological parameters of mice in each group showed a decreasing trend initially,and then increased.One week after radiotherapy,there were significant differences in platelet and white blood cell levels among the three groups(experimental group＞control group＞blank group,all P＜0.05).Two weeks after radiotherapy,there were significant differences in the percentage of adipocyte vacuole area among the three groups(experi-mental group＜control group＜blank group,all P＜0.05).Pearson correlation analysis showed a negative correlation between hematological parameters and PPARγ expression levels(all P＜0.05),as well as a negative correlation between hematological parameters and the percentage of adipocyte vacuole area(all P＜0.05).After in vitro osteogenic/adipogenic induction differenti-ation,compared to the control group,the experimental group showed a significantly lower proportion of orange-red cells and a significantly higher proportion of red calcium nodules.After 3 days of osteogenic induction differentiation,the experimental group,positive control group,and negative control group of human bone marrow stromal cells were co-cultured with mouse HSCs,while HSCs were solely cultured in the blank group.The results showed that after 24 h,48 h and 72 h of co-culture,the A values of mouse HSC cells in the experimental group and positive control group were higher than those in the negative control group and blank group(all P＜0.05).Conclusion Silencing of the PPARγ gene in HS-5 cells implanted into bone marrow-sup-pressed mice contributes to enhanced hematopoietic function in mice.After interference and silencing of the PPARγ gene,the os-teogenic differentiation ability of HS-5 cells is enhanced,while the adipogenic differentiation ability is weakened.Furthermore,osteogenic-induced HS-5 cells can further enhance the proliferation capacity of mouse HSCs.

Odontogenic keratocyst(OKC)is a common jaw cyst with a high recurrence rate.OKC combined with basal cell carcinoma as well as skeletal and other developmental abnormalities is thought to be associated with Gorlin syndrome.Moreover,OKC needs to be differentiated from orthokeratinized odontogenic cyst and other jaw cysts.Because of the different prognosis,differential diagnosis of several cysts can contribute to clinical management.We collected 519 cases,comprising a total of 2157 hematoxylin and eosin-stained images,to develop digital pathology-based artificial intelligence(AI)models for the diagnosis and prognosis of OKC.The Inception_v3 neural network was utilized to train and test models developed from patch-level images.Finally,whole slide image-level AI models were developed by integrating deep learning-generated pathology features with several machine learning algorithms.The AI models showed great performance in the diagnosis(AUC=0.935,95%CI:0.898-0.973)and prognosis(AUC=0.840,95%CI:0.751-0.930)of OKC.The advantages of multiple slides model for integrating of histopathological information are demonstrated through a comparison with the single slide model.Furthermore,the study investigates the correlation between AI features generated by deep learning and pathological findings,highlighting the interpretative potential of AI models in the pathology.Here,we have developed the robust diagnostic and prognostic models for OKC.The AI model that is based on digital pathology shows promise potential for applications in odontogenic diseases of the jaw.

Objective: To investigate the correlation between tumor size, tumor location, and prognosis in patients with early-stage endometrial cancer (EC) receiving adjuvant radiotherapy. Methods: Data of patients who had been treated for stage I–II EC from March 1999 to September 2017 in 13 tertiary hospitals in China was screened. Cox regression analysis was performed to investigate associations between tumor size, tumor location, and other clinical or pathological factors with cancer-specific survival (CSS) and distant metastasis failurefree survival (DMFS). The relationship between tumor size as a continuous variable and prognosis was demonstrated by restricted cubic splines. Prognostic models were constructed as nomograms and evaluated by Harrell’s C-index, calibration curves and receiver operating characteristic (ROC) curves. Results: The study cohort comprised 805 patients with a median follow-up of 61 months and a median tumor size of 3.0 cm (range 0.2–15.0 cm). Lower uterine segment involvement (LUSI) was found in 243 patients (30.2%). Tumor size and LUSI were identified to be independent prognostic factors for CSS. Further, tumor size was an independent predictor of DMFS. A broadly positive relationship between poor survival and tumor size as a continuous variable was visualized in terms of hazard ratios. Nomograms constructed and evaluated for CSS and DMFS had satisfactory calibration curves and C-indexes of 0.847 and 0.716, respectively. The area under the ROC curves for 3- and 5-year ROC ranged from 0.718 to 0.890. Conclusion Tumor size and LUSI are independent prognostic factors in early-stage EC patients who have received radiotherapy. Integrating these variables into prognostic models would improve predictive ability.

Objective:To investigate the safety and efficacy of four-hook needle combined with holographic image in robot-assisted partial nephrectomy for completely intrarenal tumors.Methods:The clinical data of 8 patients with completely intrarenal tumors treated by robot-assisted partial nephrectomy with four-hook needle combined with holographic image admitted to General Hospital of Central Theater Command from October 2023 to December 2023 were retrospectively analyzed. There were 6 males and 2 females, with average age of (44.5±12.0) years old. Tumors of 6 cases were in the left side and 2 cases in the right side. The maximum diameter of the tumor was (23.2±8.1) mm. The R. E.N.A.L. score was (9.0±1.4). The preoperative serum creatinine (Scr) was (73.1±14.7) μmol/L. CT-guided four-hook needle was used to locate the edge of completely intrarenal tumor before surgery. During the operation, the tumor was precisely resected under the guidance of hologram and four-hook needle. Perioperative data of patients were collected and analyzed.Results:All the tumor were successfully resected under the guidance of four-hook needle and hologram without conversion to radical nephrectomy or open surgery. The mean operative time was (117.0±14.5) min, the mean hot ischemia time was (20.2±5.1) min, the mean intraoperative blood loss was (75.0±17.3) ml, and the average hospitalization time was (9.5±1.3) days.The one week postoperative Scr was (73.2±14.8) μmol/L, which had no significant difference with that of before operation ( P=0.952). None of them received blood transfusion. The pathology results of 8 patients were clear cell renal cell carcinoma, and the surgical margins were negative. Conclusions:For completely intrarenal tumors, the four-hook needle combined with the hologram can guide the surgeon to quickly locate the tumor, accurately resect the tumor, reduce perioperative complications, and is safe and effective.

Objective:To analyze the clinical characteristics and prognosis of patients with myelodysplastic syndrome (MDS) with a bone marrow nucleated erythroid cell proportion of greater than or equal to 50% (MDS-E) .Methods:The clinical characteristics and prognostic factors of patients with MDS-E were retrospectively analyzed by collecting the case data of 1 436 newly treated patients with MDS diagnosed in the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences from May 2014 to June 2023.Results:A total of 1 436 newly diagnosed patients with complete data were included in the study, of which 337 (23.5%) patients with MDS-E had a younger age of onset and lower neutrophil and platelet counts compared with those in patients with an erythroid cell proportion of less than 50% (MDS-NE) (all P<0.05). The proportion of MDS cases with ring sideroblasts (MDS-RS) was higher in the MDS-E group than in the MDS-NE group, and multi-hit TP53 mutations were more enriched in the MDS-E group than in the MDS-NE group (all P<0.05). Among patients with MDS-RS, the frequency of complex karyotypes and the TP53 mutation rate were significantly lower in the MDS-E group than in the MDS-NE group (0 vs 11.9%, P=0.048 and 2.4% vs 15.1%, P=0.053, respectively). Among patients with TP53 mutations, the frequencies of complex karyotypes and multi-hit TP53 mutations were significantly higher in the MDS-E group than in the MDS-NE group (87.5% vs 64.6%, P=0.003 and 84.0% vs 54.2%, P<0.001, respectively). Survival analysis of patients with MDS-RS found that the overall survival (OS) in the MDS-E group was better than that in the MDS-NE group [not reached vs 63 (95% CI 53.3-72.7) months, P=0.029]. Among patients with TP53 mutations and excess blasts, the OS in the MDS-E group was worse than that in the MDS-NE group [6 (95% CI 2.2-9.8) months vs 12 (95% CI 8.9-15.1) months, P=0.022]. Multivariate analysis showed that age of ≥65 years ( HR=2.47, 95% CI 1.43-4.26, P=0.001), mean corpuscular volume (MCV) of ≤100 fl ( HR=2.62, 95% CI 1.54-4.47, P<0.001), and TP53 mutation ( HR=2.31, 95% CI 1.29-4.12, P=0.005) were poor prognostic factors independent of the Revised International Prognostic Scoring System (IPSS-R) prognosis stratification in patients with MDS-E. Conclusion:Among patients with MDS-RS, MDS-E was strongly associated with a lower proportion of complex karyotypes and TP53 mutations, and the OS in the MDS-E group was longer than that in the MDS-NE group. Among patients with TP53 mutations, MDS-E was strongly associated with complex karyotypes and multi-hit TP53 mutations, and among TP53-mutated patients with excess blasts, the OS in the MDS-E group was shorter than that in the MDS-NE group. Age of ≥65 years, MCV of ≤100 fl, and TP53 mutation were independent adverse prognostic factors affecting OS in patients with MDS-E.

Objective:To explore the predictive value of serum sorting protein (Sortilin) combined with extracellular matrix metalloproteinase inducible factor (EMMPRIN) for in stent restenosis (ISR) after carotid artery stent placement (CAS).Methods:A total of 197 patients with carotid artery stenosis who underwent CAS treatment at the Capital Medical University Daxing Teaching Hospital from January 2018 to October 2020 were selected as the study subjects. All patients were followed up for 24 months after surgery and were divided into an ISR group (28 cases) and a non ISR group (169 cases) based on the occurrence of ISR. Enzyme linked immunosorbent assay (ELISA) was used to detect and compare the preoperative serum Sortilin and EMMPRIN levels between the two groups. We collected clinical data from patients and analyzed the influencing factors of post CAS ISR using univariate and multivariate logistic regression models. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum Sortilin and EMMPRIN for postoperative ISR in CAS.Results:The serum Sortilin, EMMPRIN, age, proportion of concomitant hypertension, degree of preoperative stenosis, neutrophil count (NEUT), platelet count (PLT), white blood cell count (WBC), high-sensitivity C-reactive protein (hs-CRP), triglycerides (TG), and total cholesterol (TC) in the ISR group were higher than those in the non ISR group (all P<0.05). The results of multivariate logistic regression analysis showed that PLT, WBC, and elevated serum Sortilin and EMMPRIN were independent risk factors for the occurrence of ISR after CAS surgery (all P<0.05). ROC curve analysis showed that the AUC under the ROC curve of serum Sortilin and EMMPRIN alone and in combination for predicting postoperative ISR in CAS were 0.735(95% CI: 0.546-0.918), 0.766(95% CI: 0.615-0.910), and 0.839(95% CI: 0.701-0.984), respectively. The predictive efficacy of the combined application was greater than that of the two indicators alone. Conclusions:Patients with postoperative ISR after CAS have abnormally elevated levels of serum Sortilin and EMMPRIN before surgery, which are independent risk factors for postoperative ISR. The combined detection of serum Sortilin and EMMPRIN has good predictive value for the risk of postoperative ISR in CAS.

Background and purpose:Human epidermal growth factor receptor 2(HER2)is closely associated with drug efficacy and prognosis in urothelial carcinoma(UC).HER2 is a significant biomarker and therapeutic target in various tumors.In recent years,anti-HER2 antibody-drug conjugates have shown significant clinical efficacy in UC patients with HER2 overexpression.Therefore,an in-depth understanding of HER2 expression and its characteristics in Chinese UC patients is crucial to guide treatment decision-making,optimize treatment strategies and achieve personalized therapy.This study aimed to thoroughly investigate correlation of HER2 expression and clinicopathological characteristics in Chinese patients with UC.Methods:This study was a multicenter study that retrospectively included UC patients from urology departments of 8 tertiary hospitals in 5 geographical regions of China(North China,East China,South China,Central China and Northwest)whose tissue samples were collected from January 2023 to March 2024.Inclusion criteria:① age above 18 years;② UC diagnosed by histopathological or cytological examination;③ complete results of HER2 expression detection using immunohistochemistry(IHC)in the primary tumor site were required.Exclusion criteria:① diagnosed patients with tumors in other parts of the body;② physicians evaluated other situations that were not suitable for inclusion in this study.IHC results for HER2 expression and clinicopathological data were collected.HER2 expression was determined according to the criteria outlined in"Clinical pathological expert consensus on HER2 testing in urothelial carcinoma in China",with HER2 2+and 3+defined as HER2 overexpression.The HER2 expression and clinicopathological features were analyzed.This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(ethical number:2301268-12)and was registered at China Clinical Trial Registry(registration number:ChiCTR2300069746).Results:A total of 1054 patients with UC were included.Most of the tumors were bladder UC(n=807,76.6%).The mean age of patients was(66.8±10.5)years,and the majority were male(78.5%).The HER2 overexpression rate was 58.4%(n=616),with an additional 23%of patients having HER2 1+expression(n=242),and a small proportion exhibiting negative HER2 expression(n=196,18.6%).HER2 expression was significantly associated with various clinical and pathological characteristics such as Eastern Cooperative Oncology Group(ECOG)performance status,history of cardiovascular disease,history of metabolic disorders,smoking,UC disease location,differentiation grade,pathological type,and tumor stage.Conclusion:Retrospective analysis of multi-center data shows that HER2 expression is frequently observed in Chinese UC patients,with an overexpression rate of up to 58.4%.Furthermore,HER2 expression is closely associated with various clinical and pathological features of UC patients.This study underscores the critical importance of accurately assessing HER2 expression in UC patient to guide personalized therapies.
