Colorectal cancer （CRC） is one of the most common cancers， with its incidence ranking high among cancers. It stands as the second leading cause of cancer-related death worldwide. In the early stages， CRC lacks specific symptoms， and most patients are diagnosed at advanced stages， making it a major research focus in the field of gastrointestinal tumors. Currently， clinical CRC treatments face several common challenges， including high surgical risks， frequent metastasis and recurrence， drug resistance， and significant side effects from chemotherapy and radiation therapy. With the development and application of traditional Chinese medicine （TCM）， it has been found that TCM and its active ingredients can effectively inhibit CRC cell proliferation， invasion， migration， and angiogenesis， and promote apoptosis and autophagy， thereby slowing the progression of CRC. This has become a key focus of CRC treatment research. Salvia Miltiorrhiza has multiple pharmacological effects， including activating blood circulation to dispel blood stasis， unlocking meridians to relieve pain， clearing heat to calm irritability， and cooling blood to reduce abscesses. It contains a variety of chemical components， including diterpenoids， phenolic acids， flavonoids， polysaccharides， nitrogen-containing compounds， steroids， and lactone compounds. This review summarized the molecular mechanisms of Salvia miltiorrhiza and its active ingredients in the treatment of CRC. It is found that these ingredients exert anti-CRC effects through various molecular mechanisms， including cell cycle arrest， promotion of apoptosis， inhibition of cell invasion and migration， induction of autophagy， suppression of tumor angiogenesis， and remodeling of the tumor microenvironment. The review aims to provide new insights for the drug development and clinical application of Salvia miltiorrhiza in CRC treatment.

Objective To investigate the prevalence of scoliosis and congenital heart disease(CHD)and their correlation among children and adolescents of Drung nationality in Yunnan Province.Methods A cross-sectional survey was conducted in November 2022 among all Drung school-aged children and adolescents aged 5-18 years in Gongshan Drung and Nu Autonomous County,Yunnan Province.Visual inspection,Adams for-ward flexion test,and trunk rotation angle(ATR)measurement were comprehensively used for school prelim-inary screening of scoliosis.Individuals who tested positive in the school preliminary screening underwent fur-ther X-ray examination for auxiliary diagnosis.Cardiac auscultation and echocardiography were used for school preliminary screening of CHD.The personal information of the screening subjects,the screening results,etc.were recorded.The prevalence of scoliosis and CHD among children and adolescents of the Drung nationality and the relationship between the two diseases were statistically analyzed,and the positive predictive value of school-based scoliosis screening and its influencing factors were also analyzed.Results A total of 1 036 chil-dren and adolescents of Drung nationality were enrolled,with a mean age of(10.72±3.75)years,icluding 542 males and 494 females.A total of 45 subjects tested positive for scoliosis in the school preliminary screening,with a preliminary positive rate of 4.34%.A total of 22 cases were finally diagnosed with scoliosis,with a prevalence rate of 2.12%.Among them,21 cases were idiopathic scoliosis(accounting for 95.45%),and 1 case was congenital scoliosis(accounting for 4.55%).The prevalence rate was higher in females(2.83%)than that in males(1.48%),higher in the 10 to 18-year-old group(2.30%)than that in the 5 to<10-year-old group(1.87%),and higher in the secondary school group(2.78%)than that in the primary school group(1.78%),hut there were no statistically significant differences(P>0.05).Most idiopathic scoliosis cases were mild(Cobb angle 10° to<20°,90.48%)and classified as Lenke type Ⅴ(57.14%).Two cases of CHD were confirmed,both of which were atrial septal defects,with a prevalence rate of 0.19%.The co-occurrence rate of idiopathic scoliosis and CHD was 4.76%(1/21).The positive predictive value of school-based scoliosis pre-liminary screening was only 48.89%.When the BMI was<18.5 kg/m2,the positive predictive value was sig-nificantly higher than that for BMI≥18.5 kg/m2(P<0.05).Conclusion The prevalence rate of scoliosis a-mong adolescents of the Drung ethnic group in Yunnan Province is 2.12%,predominantly idiopathic scoliosis,with Lenke type V being the most common classification.The prevalence rate of congenital heart disease is 0.19%.BMI is a significant influencing factor for the positive predictive value of school-based scoliosis prelimi-nary screening.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

Objective:To construct an evaluation index system of internal control medical equipment based on the internal control theory of The Committee of Sponsoring Organizations of the Treadway Commission(COSO)and combined with the current situation of medical equipment internal management in public hospitals,so as to provide reference and suggestions for the evaluation of internal control of medical equipment in public hospitals.Methods:Through literature research and expert consultation,the evaluation index system of internal control of medical equipment was preliminarily determined.Using the Delphi method,15 experts from 1 medical college and 3 tertiary hospitals in Beijing who were engaged in the use and management of medical equipment were selected to conduct two rounds of consultation on the evaluation index system of internal control of medical equipment,and the evaluation indicators were scored and screened.The analytic hierarchy process(AHP)was used to determine the index weights,and the internal control evaluation index system of medical equipment in public hospitals based on COSO was constructed.Results:The coefficient of the two rounds of expert consultation was 100%.The authority degree of consulting experts was 0.867.Finally,the evaluation index system of internal control of medical equipment in tertiary public hospitals was formed,which included 5 first-level indicators,17 second-level indicators and 50 third-level indicators.Conclusion:The evaluation index of internal control of medical equipment in public hospitals based on COSO has high expert enthusiasm,authority and coordination.The evaluation index system includes the unit level and the business level of internal control,with a wide coverage,which makes up for the limitations of traditional internal evaluation of medical equipment,which can make up for the limitations of the internal evaluation of traditional medical equipment,improve the internal control system of medical equipment in public hospitals,and optimize the medical equipment management system.

Objective:To construct an effectiveness evaluation model of internal control of medical equipment in public hospitals based on fuzzy analytic network process(F-ANP),and to improve the level of internal control management of medical equipment in hospitals.Methods:Through literature research and analysis,based on the internal control theory system of The Committee of Sponsoring Organizations of the Treadway Commission(COSO),combined with the characteristics of medical equipment management in public hospitals,the effectiveness evaluation model of internal control of medical equipment in public hospitals was established by F-ANP,which was combining analytic network process(ANP)and fuzzy comprehensive evaluation.An empirical analysis was carried out on the internal control of medical equipment in Beijing Friendship Hospital,Capital Medical University.Results:The index system for model evaluation included 5 first-level indicators of control environment,risk evaluation,control activities,information exchange,and supervision mechanism,17 second-level indicators,and 50 third-level indicators.The model was used to evaluate the effectiveness of internal control of medical equipment in the hospital,its maximum membership value was 0.133 7,and the result was"relatively effective",indicating that the construction and implementation of internal control of medical equipment in the hospital were relatively perfect,while the management of scrapping of medical equipment,cost control and equipment informatization construction still need to be improved.Conclusion:The effectiveness evaluation model of internal control of medical equipment of public hospitals based on F-ANP can provide certain reference value for evaluation of the effectiveness of internal control of medical equipment in public hospitals,which is conducive to standardizing internal control of medical equipment,promoting the fine management of medical equipment and ensuring the safety of medical equipment assets.

Objective To investigate the clinicopathological features,immunophenotypes,molecular genetic alterations,and prognosis of succinate dehydrogenase-deficient renal cell carcinoma(SDH-RCC).Methods A total of 11 cases of SDH-RCC diagnosed at West China Hospital,Sichuan University between 2016 and 2023 were selected for clinicopathological,immunohistochemical,and DNA sequencing analyses.Results Among the 11 cases of SDH-RCC,there were 5 male patients and 6 female patients.The patients'ages ranged from 12 to 71 years,with an average age of 39.7 years.Among them,5 patients had tumors located in the right kidney,5 had tumors located in the left kidney,and 1 patient had bilateral tumors.Microscopic observation showed that the tumor cells of the SDH-RCC patients displayed a wide spectrum of structures,forming sheet-like,nested,and glandular structures.In addition,tumor cells in papillary structures were observed in some cases.The tumor cells had abundant cytoplasm,was eosinophilic,and contained flocculent materials.Intracytoplasmic vacuolations were observed in some of the cells.Among all the patients,7(7/11,63.6％)showed typical low-grade features(grade 1-2 according to the International Society of Urological Pathology[ISUPJ/WHO 2016 classification),and 4(4/11,36.4％)showed high-grade features(grade 3 according to the ISUP/WHO 2016 classification).The average ages of patients with low-grade and high-grade features were 32.1 years and 58.0 years,respectively.Immunohistochemical staining of all 11 cases demonstrated negative results for SDHB and cytokeratin 7(CK7),and positive staining results for paired box 8(PAX-8),fumarate hydratase(FH),and epithelial membrane antigen(EMA).Their Ki-67 index was l％-30％.In one case,the loss of SDHB expression was also accompanied by a loss of SDHA expression.Sanger sequencing was performed to examine all the exons of SDHB in 7 cases.One case showed a frameshift mutation,c.236Tdel(p.K80Rfs*),and another case harbored a missense mutation,c.725G＞A(p.Arg242His).In another case,next generation sequencing revealed that large fragments of SDHB(Exon 4-8 del)were missing.Follow-up data were available for 10 patients.The follow-up time ranged from 4 to 138 months,with the average being 32.8 months,and all patients survived.Metastasis and recurrence were reported in 5 cases,with 3 of them showing high-grade features and 2 showing low-grade features.Conclusion SDH-RCC is rare and the patients demonstrate a relatively young age of onsets.Patients may present with bilateral tumors.Tumors with low-grade features usually occur in young patients,with their Ki-67 index usually being lower than 5％.Individual cases may experience tumor recurrence and metastasis over a long period of follow-up.Tumors with high-grade features tend to occur in older patients who have a higher Ki-67 index,and who are prone to recurrence and metastasis.Negative immunohistochemical staining results for SDHB can assist in tumor diagnosis,but the loss of SDHB protein expression does not necessarily lead to the detection of SDHB gene mutation.

Objective:To analyze the clinicopathological characteristics of differentiated early cardia cancer and to evaluate the short-term and long-term efficacy of endoscopic submucosal dissection (ESD).Methods:A total of 329 patients (331 lesions) who underwent ESD at Nanjing Drum Tower Hospital from October 2014 to December 2019 and were pathologically confirmed as differentiated early cardia cancer were included in the study and followed up. The endoscopic and pathological data of patients were reviewed to analyze the clinicopathological characteristics of differentiated early cardia cancer. The short-term (including en bloc resection rate, curative resection rate and incidence of short-term complications) and long-term efficacy (including incidence of metachronous cancer, recurrence and distant metastasis, and overall survival rate) of ESD was evaluated.Results:The ratio of male to female in 329 patients with differentiated early cardia cancer was 4∶1, and their age was 65.69±8.02 years. Tumor diameter of ≤2.0 cm accounted for 65.9% (218/331). Most lesions were located on the posterior wall (50.5%, 167/331), followed by the minor curve (36.3%, 120/331). The endoscopic morphology of 0-Ⅱc type accounted for 49.5% (164/331). There were 69.8% (231/331) lesions confined to the mucosal layer. The en bloc resection rate was 100.0% (329/329), and the curative resection rate was 83.3% (274/329). Short-term complications occurred in 28 patients (8.5%). With a median follow-up time of 39 months, 11 patients (3.3%) developed metachronous cancer, 2 (0.6%) developed distant metastasis, and no recurrence occurred. Seven patients died, and the overall survival rate during the follow-up period was 97.9% (322/329). The survival rate of patients with curative resection and additional surgery was 100.0% (3/3), while that without additional surgery was 99.3% (269/271). The survival rate of patients with non-curative resection and additional surgery was 96.0% (24/25), and that without additional surgery was 86.7% (26/30).Conclusion:Most differentiated early cardia cancers are well-differentiated adenocarcinomas, with less than 2 cm in diameter at the time of diagnosis with a low rate of ulcer and vascular invasion. ESD is safe and effective for the treatment of differentiated early cardia cancer with a high rate of curative resection, fewer intraoperative and postoperative complications, low incidences of metachronous cancer, distant metastasis and recurrence, and a high overall survival rate. However, additional surgical treatment is recommended for patients with non-curative resection.

Genome-wide physical protein-protein interaction(PPI)mapping remains a major chal-lenge for current technologies.Here,we reported a high-efficiency BiFC-seq method,yeast-enhanced green fluorescent protein-based bimolecular fluorescence complementation(yEGFP-BiFC)coupled with next-generation DNA sequencing,for interactome mapping.We first applied yEGFP-BiFC method to systematically investigate an intraviral network of the Ebola virus.Two-thirds(9/14)of known interactions of EBOV were recaptured,and five novel interactions were discovered.Next,we used the BiFC-seq method to map the interactome of the tumor protein p53.We identified 97 interactors of p53,more than three-quarters of which were novel.Furthermore,in a more complex background,we screened potential interactors by pooling two BiFC libraries together and revealed a network of 229 interactions among 205 proteins.These results show that BiFC-seq is a highly sensitive,rapid,and economical method for genome-wide interactome map-ping.

Objective To investigate whether elevated parathyroid hormone (PTH) levels could induce endothelial - to - mesenchymal transition (EndMT) and adipocyte transition in endothelial cells (ECs), and to determine the possible underlying mechanism. Methods (1) A rat model of secondary hyperparathyroidism and chronic kidney disease (CKD) was established. The adiposity in bone marrow was detected by oil red O staining. Immunofluorescence staining was performed to detect the expression and localization of cluster of differentiation 31 (CD31) and fibroblast-specific protein 1 (FSP1). (2) The human umbilical vein ECs were cultured in vitro. Western blotting was performed to detect protein expressions of EndMT-related markers CD31, FSP1 and α-smooth muscle actin (α-SMA) in interference groups with different PTH concentrations (0, 10-11, 10-9, 10-7 mol/L PTH for 48 h) and times (0, 12, 24, 48 h, 10-7 mol/L PTH), as well as the expression of β-catenin in interference groups with different PTH concentrations. The localizations of CD31, FSP1 and β - catenin were observed by cell immunofluorescence. Protein expressions of adipocytes markers peroxisome proliferator - activated receptor-γ (PPAR-γ) and CCAAT/enhancer binding protein-α (C/EBP-α) by Western blotting and the degree of adipogenesis by oil red O staining were detected after transformed ECs were cultured in adipogenic culture medium for one week. Small interfering RNA (siRNA) was performed to silenceβ - catenin expression. ECs were divided into control siRNA group, β - catenin siRNA group, PTH +control siRNA group and PTH+β-catenin siRNA group. Protein expressions of CD31, FSP1 and PPAR-γby Western blotting and the degree of adipogenesis by oil red O staining were determined. Results (1) In vivo, compared with the control, CKD rats had increased adipocytes in bone marrow (P＜0.05), and the co-expression of CD31 and FSP1 in bone marrow ECs. (2) In vitro, PTH significantly inhibited the expression of endothelial marker CD31 and increased the expressions of mesenchymal markers FSP1 and α-SMA in concentration-and time-dependent manners. These indexes in 10-7 mol/L PTH group and 0 mol/L PTH group, in 48 h group and 0 h group showed statistical differences (all P＜0.05). In PTH group ECs with 10-7 mol/L PTH for 48 h showed FSP1 accumulation in the cytoplasm and reduced expressions of CD31, and ECs had higher expressions of PPAR-γ and C/EBP-α as well as the degree of adipogenesis than those in control group (all P＜0.05). Furthermore, PTH enhanced the nuclearβ-catenin protein levels in ECs in concentration-dependent. The expressions of β-catenin in 10-7 mol/L PTH group and 0 mol/L PTH group showed statistical differences (P＜0.05). β - catenin expressed in the cytoplasm in control group, while it enter into the nucleus in PTH group. Compared with those in PTH+control siRNA group, the expressions of CD31 and PPAR-γ as well as the degree of adipogenesis decreased in PTH+β-catenin siRNA group (all P＜0.05), while the expression of FSP1 increased (P＜0.05). Conclusions PTH induces ECs - to - adipocytes transition by the canonical Wnt/β - catenin signaling pathway, which might account for bone loss in CKD. Silenced β - catenin expression can inhibit PTH-induced EndMT and adipogenesis.
