Endometrial cancer is one of the common malignant tumors of the female reproductive system.Its incidence rate in China is second only to cervical cancer,posing a serious threat to women's life and health,and the onset shows a trend of affecting younger individuals.Currently,the primary treatment for endometrial cancer is surgical intervention,and some postoperative patients and those with postoperative recurrence require adjuvant radiotherapy.Pelvic external beam radiotherapy(EBRT)and vaginal brachytherapy(VBT)are two modalities of postoperative radiotherapy.The appropriate postoperative radiotherapy approach should be selected based on individual conditions and guideline recommendations.Most patients can achieve satisfactory treatment outcomes through surgery and postoperative adjuvant radiotherapy.However,the specific indications for postoperative radiotherapy in endometrial cancer patients and the radiotherapy principles for those with postoperative recurrence are relatively complex,and recommendations for radiotherapy modalities in postoperative patients vary slightly across different guidelines.This article reviews the treatment principles for endometrial cancer patients in recent years,as well as the indications for postoperative and post operative recurrent radiotherapy and the radiotherapy techniques,aiming to provide a reference for radiotherapy in the endometrial cancer patients.

Objective To compare the surgical outcomes of the sequence of screw and rod placement for Lenke type 5C adolescent idiopathic scoliosis(AIS).Methods Lenke type 5C AIS patients who underwent posterior orthopedic fusion and fixation in our hospital from Jan.2013 to Dec.2020 were recruited.Based on surgical sequences,22 cases were assigned to bilateral group(after bilateral screw placement,orthopedics was performed on the convex side and then on the concave side),and 20 cases were assigned to convex group(screws placed on the convex side and performed orthopedics,followed by the concave side).The operation-related indicators(including operation time),imaging parameters,quality of life scores were compared between the 2 groups before and 2 years after surgery.Complications of the 2 groups were analyzed.Results The operation time in the bilateral group was significantly longer than that in the convex group([232.8±13.1]min vs[198.4±16.5]min,P＜0.01).At the last follow-up 2 years after operation,the Cobb angle and its correction rate in the convex group were better than those in the bilateral group([8.0±2.3]° vs[9.9±3.2]°,P=0.03;[81.9±5.4]%vs[77.8±5.8]%,P=0.02).The rate of pedicle screw breach rate was 5.4%(17/312)in the bilateral group and 1.4%(4/280)in the convex group,with significant difference(P＜0.01).At the last follow-up 2 years after operation,the treatment satisfaction of quality of life assessment of the bilateral group was 4.61±1.38,and that of the convex group was 4.50±1.44,but there was no significant difference between the 2 groups(P＞0.05).There were no abnormal electrophysiological monitoring or operation-related complications in the 2 groups.Conclusion For Lenke type 5C AIS,the convex side of pedicle screw placement and orthopedics followed by concave side of pedicle screw placement and orthopedics can achieve better surgical effect.

In the past, aortic dissection, aortic aneurysm, and other aortic diseases, primarily rely on surgical intervention. In recent years, due to breakthroughs in materials science, endovascular therapy has become the first choice for the surgical treatment of most aortic diseases. However, traditional endovascular repair cannot fully meet the clinical needs for certain complex lesions involving the aortic arch and the originations of visceral arteries. The emergence of physician-modified stent technology has brought new hope for the treatment of complex aortic diseases. This article provides a detailed introduction to the concept, development, technical characteristics, and applications of physician-modified stents in the treatment of aortic diseases, analyzing their advantages and limitations. Physician-modified stents serve as a powerful complement to traditional endovascular interventions and commercial branched stents, yet further research and refinement are still required.

Objective:To compare the efficacy and safety of Rotarex mechanical thrombectomy (Rotarex) combined with drug-coated balloon (DCB) versus percutaneous transluminal angioplasty (PTA) combined with DCB in the treatment of femoropopliteal artery in-stent restenosis (ISR).Methods:A multicenter, prospective, randomized controlled trial was conducted. 46 patients with femoropopliteal artery ISR admitted to five hospitals (Beijing Friendship Hospital, Capital Medical University; Beijing Chaoyang Hospital, Capital Medical University; Beijing Jishuitan Hospital, Capital Medical University; Xuanwu Hospital, Capital Medical University; Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University) from July 2020 to June 2024 were enrolled. Patients were randomly divided into the Rotarex+ DCB group ( n=24) and the PTA+ DCB group ( n=22) using a random number table. The clinical data of the two groups were collected, including clinical characteristics, Fontaine classification, stent placement location, stent duration, and lesion length. The primary endpoint was the target blood vessel patency rate at 6 and 12 months postoperatively; the secondary endpoints included improvement in clinical symptoms (Fontaine classification), rate of reintervention, and safety indicators. Measurement data were expressed as mean±standard deviation ( ± s), and the t-test was used for comparison between groups; count data were expressed as the number of cases and percentages, and intergroup comparisons were performed using the Chi-test or Fisher exact probability method. Results:At 12 months postoperatively, the target blood vessel patency rate in the Rotarex+ DCB group was significantly higher than that in the PTA+ DCB group (81.8% vs 45.5%, P=0.012), and the proportion of patients in Fontaine classification stage I was also higher (86.4% vs 45.5%, P=0.004). The results at the 6-month follow-up were consistent (target blood vessel patency rate: 87.0% vs 59.1%, P=0.035). In terms of safety, no severe complications such as arterial rupture, amputation, or procedure-related death occurred during the perioperative period in either group. During the postoperative follow-up, no amputation or procedure-related deaths occurred in either group. Conclusion:For the treatment of femoropopliteal artery ISR, Rotarex mechanical thrombectomy combined with DCB is significantly superior to PTA+ DCB in terms of 12-month target blood vessel patency rate and improvement of clinical symptoms, with comparable safety.

Inflammatory bowel disease （IBD）， consisting of ulcerative colitis and Crohn's disease， is a chronic relapsing inflammatory gastrointestinal disease closely associated with immune dysfunction. The pathogenesis of IBD is closely related to genetic susceptibility， immune system dysfunction， environmental change， and intestinal microbial dysbiosis. Modern research has found that macrophage polarization plays an important role in the development of IBD and can affect the level of inflammatory response， intestinal mucosal repair， and intestinal microbial balance， making it a potential target for IBD treatment. Increasing evidence suggests that traditional Chinese medicine and its active components can regulate macrophage polarization through multiple pathways and balance the M1/M2 macrophage ratio， thus inhibiting inflammatory response， promoting intestinal mucosal repair， and slowing down the progression of IBD. This article summarized the biological processes and targets involved in macrophage polarization and discussed its impact on IBD. It also provided a brief overview of the latest research on how traditional Chinese medicine and its active components can improve IBD by regulating macrophage polarization， so as to provide new directions and strategies for the clinical application of traditional Chinese medicine in IBD treatment.

BACKGROUND:Osteoarthritis is a chronic degenerative disease of skeletal muscle,and the incidence of osteoarthritis is increasing yearly,but its pathogenesis is not clear.The commonly used drugs for osteoarthritis include non-steroidal anti-inflammatory drugs and glucocorticoid.Adverse drug reactions to these drugs can reduce patient compliance and ultimately affect the efficacy of treatment.Active ingredients in Chinese medicine are closely scrutinized for their safety and other characteristics. OBJECTIVE:Through reviewing the research progress in the effect of active ingredients of traditional Chinese medicine on osteoarthritis-related signaling pathways,to provide ideas and theoretical basis for the research,development,and application of new drugs in the prevention and treatment of osteoarthritis. METHODS:CNKI,WanFang,VIP,PubMed,and GeenMedical were searched for relevant literature in the last 10 years.The key words were"OA,osteoarthritis,traditional Chinese medicine,active ingredients of traditional Chinese medicine,chondrocyte,inflammation,signal pathways,mechanism"in Chinese and English.We excluded the irrelevant repetitive and older literature,and finally included 63 articles for further review. RESULTS AND CONCLUSION:The active ingredients of traditional Chinese medicine regulate the levels of inflammatory factors,promote the proliferation and differentiation of chondrocytes,regulate the apoptosis of chondrocytes,and delay the degeneration of chondrocytes through Wnt/β-catenin,NK-ΚB,P38 MAPK,PI3K/AKT,JAK2/STAT3 and other signaling pathways,thus slowing the progression of osteoarthritis.

Objective To investigate and evaluate the safety and effectiveness of the Chimney technique in mitral valve reoperation. Methods The clinical data of mitral valve reoperation patients who underwent Chimney surgery in Wuhan Asia Heart Hospital from 2019 to 2021 were retrospectively analyzed. Results A total of 26 patients were collected, including 7 males and 19 females, aged 27-67 (53.46±11.18) years. All patients had previous mitral valve surgery, including 23 mitral valve replacements and 3 mitral valve repairs. All patients received Chimney technique using the ideal artificial sized mitral valve, and 1 patient died of neurological complications in hospital. The cardiopulmonary bypass time and the aortic cross-clamping time were 231.11±77.05 min and 148.50±52.70 min, respectively. The mean diameter of the implanted mitral valve prosthesis was 29.08±0.68 mm, which was statistically different from pre-replacement valve prosthesis size of 26.69±0.77 mm (P＜0.001). The mean transvalvular pressure gradient of the prosthetic mitral valve measured on postoperative echocardiography was 14.77±5.34 mm Hg, which was statistically different from preoperative value of 20.92±9.83 mm Hg (P=0.005). Conclusion The Chimney technique is safe and effective for reoperation in patients with small mitral annuli, which can not only reduce the risk of reoperation, but also obtain larger prosthetic valve implants with good hemodynamic characteristics and clinical outcomes.

Objective To investigate and evaluate the safety and efficacy of the aortic-mitral annular enlargement technique (double annular enlargement) in patients with small-size valve prostheses after prior valve surgery. Methods The clinical data of patients who underwent double valve annular enlargement in Wuhan Asia Heart Hospital from April 2020 to April 2022 were retrospectively analyzed. Results A total of 30 patients were collected, including 2 males and 28 females aged 9-78 (52.71±3.53) years. All patients had previous heart valve surgery, including 1 patient receiving the third heart surgery. All patients were operated on successfully and there were no postoperative in-hospital deaths. There was no postoperative bleeding which needed a secondary open-chest hemostasis, and one patient underwent permanent pacemaker implantation due to postoperative sick sinus syndrome. The mean diameter of the implanted prosthetic aortic valve was 24.23±1.60 mm, which was significantly larger than that of the preoperative aortic valve (21.03±1.90 mm, P＜0.001). The mean diameter of the implanted prosthetic mitral valve was 28.33±1.21 mm, which was significantly larger than that of the preoperative mitral valve (25.43±0.84 mm, P＜0.001). The mean peak gradient difference across the prosthetic aortic valve on postoperative echocardiography was 18.17±6.44 mm Hg, which was significantly lower than that of the preoperative aortic valve (82.57±24.48 mm Hg, P＜0.001). The mean peak gradient difference of the postoperative prosthetic mitral valve was 12.73±5.45 mm Hg, which was significantly lower than that of the preoperative mitral valve (19.43±8.97 mm Hg, P=0.003). Conclusion The double annular enlargement technique is safe and effective for reoperation in patients with a history of valve surgery with a small aortic root to obtain both a larger size prosthetic valve for a larger orifice area and stability of the mitral-aortic valve union, resulting in good postoperative hemodynamic characteristics and clinical outcomes.

Epilepsy is a disease of the central nervous system caused by excessive neuronal discharges in the brain,characterized by sudden,recurrent and self-limited onset. The brain's qi collateral and the brain neural network are highly correlated and internally consistent in terms of structure and function. The theory of "brain's qi collateral-abnormal collateral",which is centered on the structural disorder and dysfunction of brain's qi collateral leading to the poor circulation of brain's qi collateral,can comprehensively explain the related pathogenesis of epilepsy and the law of disease evolution,so it has important clinical value. Taking the pathogenic characteristics as an entry point and based on the theory of "brain's qi collateral-abnormal collateral",this paper argues that phlegm and qi stagnation,wind in the brain's qi collateral,and phlegm and blood stagnation damaging the brain's collaterals,as well as the structural and functional characteristics of brain's qi collateral that circulate bi-directionally are the key factors for epilepsy to present sudden,recurrent,and self-limited characteristics. According to the therapeutic principle of "Collaterals need to be unobstructed to function normally",it is proposed that the method of regulating the qi and collaterals should be used as the basic treatment principle throughout the treatment. In addition,the method of resolving phlegm and eliminating blood stasis is supplemented for different pathological changes,while combining the syndrome differentiation of zang-fu viscera and attaching importance to the accompanying symptoms of epileptic seizures,to regulate the brain's qi collateral to achieve the effects of wind quenching and epileptic arrest. This is to provide reference for the treatment of epilepsy in traditional Chinese medicine.
