Objective To compare the oncologic safety, surgical efficacy, and aesthetic outcomes between conventional breast-conserving surgery and axillary single-port incision insufflation endoscopic breast-conserving surgery with mini-latissimus dorsi surgery in early breast cancer patients. Methods A retrospective analysis of clinical data from 62 female patients with early breast cancer was performed. Patients were divided into two groups on the basis of surgical method: the conventional group (37 cases) and the endoscopic group (25 cases).The clinical baseline data, surgical results, and postoperative effects of the two groups were compared. Results According to the clinical baseline data, the endoscopic group had a greater maximum tumor diameter and a greater tumor-to-breast volume ratio due to expanded indications for breast-conserving surgery (P<0.001), whereas the other data revealed no statistically significant difference between the two groups (P>0.05). Compared with those in the conventional group, the total incision length in the endoscopic group was shorter [3.40(3.15, 3.60) cm vs. 7.30 (6.50, 7.60) cm, P<0.001], the postoperative drainage volume was lower (206.20±35.11 ml vs. 223.95±26.17 ml, P=0.026), but the operative time was longer (254.92±22.67 min vs. 146.78±13.01 min, P<0.001). The incision margin positive rate was 0% (0/25) in the endoscopic group, which was significantly lower than the 10.8% (4/37) in the conventional group (P=0.141). The endoscopic group had a lower incidence of complications (4% vs. 27%, P=0.047) and superior JBCS aesthetic scores at the 6-month follow-up (76% vs. 43.2%, P=0.006). Conclusion Axillary single-port incision insufflation endoscopic breast-conserving surgery with mini-latissimus dorsi surgery is not inferior to conventional procedures in terms of oncologic safety (margin-negative rate) and offers advantages in terms of scar concealment, fewer complications, and better aesthetic outcomes, especially suitable for early breast cancer patients with small-to-medium breast volumes, tumors located in the outer quadrants and mastectomy ratios of >20%.

Objective To explore the effectiveness of an integrated laparoscopic simulation training course (best essential surgical technique training, BEST) in enhancing laparoscopic peritoneal suturing techniques in surgical residents.Methods As an integrated two-stage program, the BEST course applied basic laparoscopic training system with simple molds in phase Ⅰ training, and then adopted advanced laparoscopic training system, 3D Laparoscope and ex-vivo animal models in phase Ⅱ training. The laparoscopic suturing techniques were practiced in phase Ⅱ training. From August 2021 to July 2024, surgical residents in the second year of the national standardized training program were divided into pilot and control groups based on whether they had undergone the BEST course. Two cases of laparoscopic peritoneal suture were performed by the surgical residents under supervision in the department of gastrointestinal surgery. The operative time, quality of suture, and independent completion rate were compared between the two groups.Results A total of 33 surgical residents (19 in pilot group and 14 in control group) were included in this study, and a total of 66 cases of laparoscopic peritoneal suture were performed (38 in pilot group and 28 in control group). The operative time was significantly shorter in pilot group than that in control group (15.7 min vs. 17.5 min, P=0.025). The quality of suture was significantly better in pilot group compared to control group (P=0.023). In pilot group, all peritoneal sutures were performed by residents independently, whereas in control group, 3 cases (10.7%) were assisted by the supervisor, and the independent completion rate was different significantly (P=0.039).Conclusions The BEST course can help improve surgical residents′ laparoscopic peritoneal suturing techniques and could be promoted in the national standardized training program for surgical residents.

Nuanjian Jian(Decoction for Warming Liver Meridian),originating from Jing Yue Quan Shu(Jingyue's Complete Works)written by Zhang Jingyue,is composed of Angelicae Sinensis Radix(Danggui),Lycii Fructus(Gouqizi),Poria(Fuling),Fructus Foeniculi(Xiaohuixiang),Cinnamomi Cortex(Rougui),Linderae Radix(Wuyao),and Aquilariae Lignum Resinatumd(Chenxiang)or Aucklandiae Radix(Muxiang).Nuanjian Jian is a widely-used classical formula for warming the liver and kidneys,promoting qi circulation and alleviating pain.It was included in the Ancient Classical Formulas Catalog(First Batch)published by the National Administration of Traditional Chinese Medicine in 2018,and was primarily used to treat lower abdominal pain,hernia,and other disorders differentiated as the syndrome of cold stagnation in the liver and kidneys.Based on the principles of key information verification for classical formulas,this article systematically reviewed the ancient and modern literature on Nuangan Jian,and conducted a comprehensive textual research and analysis of its origin,composition,dosage,method of making a decoction and taking medicines,processing,modifications,historical and modern applications,and experimental studies.The study concluded that the composition and dosage of this formula are relatively clear.The contemporary single-dose equivalents are calculated as Danggui 9.33 g,Gouqizi 11.19 g,Fuling 7.46 g,Xiaohuixiang 7.46 g,Rougui 5.60 g,Wuyao 7.46 g,and Chenxiang 3.73 g.The decoction is prepared by adding 300 mL of water and 4 g of ginger,boiling until reduced to 140 mL,and taken 2-3 times daily,2 hours after meals.Modern practitioners have expanded the indications of this formula,extending its use from hernia and lower abdominal pain to various disorders in andrology,gynecology,and gastroenterology.The indications have the core pathogenesis of cold stagnation in the liver meridian,and usually affect the liver while also involve the spleen,kidneys,and lower energizer.Diseases of the lower abdomen,genitals,and breasts belonging to the region of the liver-meridian route,are also commonly treated with Nuangan Jian.The findings of this study provide a reference for the further development of this classical formula.

Objective To discuss the efficacy of transcatheter arterial chemoembolization(TACE)in combination with targeted therapy and immune checkpoint inhibitors for advanced hepatocellular carcinoma(HCC),and to identify the influencing factors.Methods A total of 60 patients with advanced HCC,who were admitted to the Air Force Medical Center of China from January 2016 to December 2022,were enrolled in this study.Thirty patients received TACE combined with targeted therapy and immune checkpoint inhibitors(TACE-L-P group),and the other 30 patients received TACE combined with targeted therapy(TACE-L group).The progression-free survival(PFS),overall survival(OS),disease control rate(DCR),and objective response rate(ORR)were compared between the two groups.Results In the TACE-L group and TACE-L-P group,the median PFS(mPFS)was 7 months and 10 months respectively(P=0.011),the median OS(mOS)was 15.5 months and 29 months respectively(P=0.014).Child-Pugh class B(HR=3.89,95％CI:1.27-11.94,P=0.018)and Barcelona Clinic Liver Cancer(BCLC)stage C(HR=2.83,95％CI:1.32-6.03,P=0.007)were the independent risk factors for OS,while micro wave ablation(HR=0.21,95％CI:0.07-0.63,P=0.005)and TACE-L-P(HR=0.09,95％CI:0.03-0.3,P=0.001)were the independent protection factors for OS.Besides,elevated bilirubin level(HR=1.03,95％CI:1-1.06,P=0.032)and elevated gamma-glutamyl transferase(GGT)level(HR=1.01,95％CI:1-1.01,P=0.002)were the independent risk factors for disease progression,and TACE-L-P(HR=0.27,95％CI:0.09-0.79,P=0.017)was the independent protection factor for disease progression.The ORR and DCR in TACE-L-P group were remarkably higher than those in TACE-L group,which were 43.4％vs 13.3％and 63.4％vs 23.3％respectively,the differences between the two groups were statistically significant(both P＜0.05).Conclusion In treating advanced HCC,TACE combined with targeted therapy and immune checkpoint inhibitors is superior to TACE combined with targeted therapy in therapeutic efficacy.

Objective To investigate the clinical application value of MRI Radiomics score(Radscore)combined with clinicopatho-logical features in predicting postoperative progression-free survival(PFS)of patients with endometrial cancer(EC).Methods A total of 127 patients with EC were selected.The radiomic features of the lesions were extracted from T2 WI,diffusion weighted imaging(DWI)and apparent diffusion coefficient(ADC)images.The features were screened by random forest model and Radscore was calcu-lated.Simultaneously,clinical and pathological characteristics of patients were collected and incorporated,and multivariate Cox regression analysis was used to screen the risk factors related to PFS.The MRI Radscore and clinicopathological features were mapped to the nomogram,and the performance of nomogram was evaluated by receiver operating characteristic(ROC)curve and calibration curve.Results Multivariate Cox regression analysis showed that progesterone receptor(PR),human epididymis protein 4(HE4)and MRI Radscore were independent risk factors for predicting PFS in patients with EC(P＜0.05).The area under the curve(AUC)of the predicted PFS at 1,3 and 5 years after surgery were 0.91,0.804 and 0.776,respectively.Calibration curves showed that nomogram had a good fit in predicting PFS in patients with EC 1,3 and 5 years after surgery.Conclusion The nomogram con-structed based on multi-sequence MRI Radscore and clinicopathological features has favorable accuracy and stability in predicting postoperative PFS in individuals diagnosed with EC.

Objective To investigate the imaging manifestations of inflammatory bowel disease-associated spondyloarthritis(IBD-SpA).Methods A retrospective analysis was conducted on 85 patients with inflammatory bowel disease(IBD)who underwent abdominal CT and MRI examinations.Patients with pregnancy,lactation,psoriasis,tumors,and other conditions were excluded through medical record screening,all patients met the diagnostic criteria for IBD.The presence of spondyloarthritis(SpA)was confirmed through ima-ging findings,and the imaging characteristics of the location and bone changes of SpA were observed.Twenty patients who under-went abdominal CT examination during the same period were selected as the control group.Results A total of 85 patients with IBD under-went CT and MRI examinations,the detection rate of MRI(37.6％)was significantly higher than that of CT(30.6％)(P＜0.05).Based on comprehensive imaging features,5 cases of grade 1,13 cases of grade 11,11 cases of grade Ⅲ,and 3 cases of grade Ⅳ,IBD-SpA were diagnosed.In the control group,1 case of sacroiliitis was detected,of which 1 case of grade Ⅱ.The detection rate of CT in the IBD group(30.6％)was significantly higher than that in the control group(5％)(P＜0.05).Conclusion The incidence of SpA is relatively high in patients with IBD.Both CT and MRI have certain diagnostic value for IBD-SpA.CT has diagnostic advantages in bone sclerosis and joint space narrowing,while MRI can better reflect minor lesions and early bone marrow edema changes.The com-bination of CT and MRI examinations can provide diagnostic evidence for clinicians and effectively improve patient symptoms.

Chimeric antigen receptor (CAR)-T cell therapy has achieved remarkable success in the treatment of hematological malignancies. Based on the immunomodulatory capability of CAR-T cells, efforts have turned toward exploring their potential in treating autoimmune diseases. Bibliometric analysis of 210 records from 128 academic journals published by 372 institutions in 40 countries/regions indicates a growing number of publications on CAR-T therapy for autoimmune diseases, covering a range of subtypes such as systemic lupus erythematosus, multiple sclerosis, among others. CAR-T therapy holds promise in mitigating several shortcomings, including the indiscriminate suppression of the immune system by traditional immunosuppressants, and non-sustaining therapeutic levels of monoclonal antibodies due to inherent pharmacokinetic constraints. By persisting and proliferating in vivo, CAR-T cells can offer a tailored and precise therapeutics. This paper reviewed preclinical experiments and clinical trials involving CAR-T and CAR-related therapies in various autoimmune diseases, incorporating innovations well-studied in the field of hematological tumors, aiming to explore a safe and effective therapeutic option for relapsed/refractory autoimmune diseases.
