To summarize Professor DING Ying's clinical experience in treating children's IgA nephropathy from the perspective of "wind-induced water turbidity". It is believed that the core pathogenesis of IgA nephropathy in children is the wind stimμlating water to become turbidity， and the basic treatment principles are to eliminate wind and settle viscera， and to remove turbidity and drain water. For those with the syndrome of wind-heat invading the lungs and injury to blood collaterals， modified Yinqiao Powder （银翘散） combined with Xiaoji Decoction （小蓟饮子） could be used； for those with dampness-heat in Sanjiao， heavy dampness and light heat pattern， modified Sanren Decoction （三仁汤） combined with Bazheng Powder （八正散） could be used； for those with lung-spleen qi deficiency and kidney essence depletion pattern， modified Buzhong Yiqi Decoction （补中益气汤） combined with Wuzi Yanzong Pill （五子衍宗丸） could be used； for those with deficiency of both qi and yin， kidney deficiency with stasis pattern， self-prescribed Yishen Huazhuo Formula （益肾化浊方） could be used. Meanwhile on the basis of pattern identification and treatment， rattan-type herbs could be combined in use in order to unblock the meridians and collaterals.

OBJECTIVE: To investigate the effectiveness of Youngswick-Akin osteotomy in the treatment of moderate hallux valgus combined with mild to moderate hallux rigidus. METHODS: The clinical data of 43 patients with moderate hallux valgus combined with mild to moderate hallux rigidus who were admitted between August 2019 and August 2022 and met the selection criteria were retrospectively analyzed. There were 8 males and 35 females. The age ranged from 28 to 77 years, with an average age of 59.0 years. The disease duration ranged from 10 to 35 months, with an average of 20 months. The degree of hallux rigidus included 2 cases of CoughlinⅠ degree, 29 cases of Ⅱ degree, 12 cases of Ⅲ degree. The preoperative hallux valgus angle ranged from 25° to 40°, with an average of 32°. All patients were treated with Youngswick-Akin osteotomy. The first metatarsophalangeal joint space was compared before operation and at 6 months after operation. The American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were used to evaluate the functional recovery and pain relief of the patients before operation and at 6 and 24 months after operation. According to the severity of hallux rigidus, the patients were divided into mild group (Ⅰ, Ⅱ degree) and moderate group (Ⅲ degree) to compare the prognosis, including the changes of AOFAS score, VAS score, and the first metatarsophalangeal joint space. RESULTS: The operation time was 60-75 minutes (mean, 65 minutes). The intraoperative blood loss was 10-30 mL (mean, 20 mL). Two cases had superficial infection of the incision margin after operation, and healed well after dressing change and antibiotic treatment. The incisions of the other patients healed by first intention, and no medial cutaneous nerve injury of the great toe occurred. All patients were followed up 24-31 months, with an average of 25.8 months. The patient's hallux valgus deformity was corrected without recurrence; no complication such as osteomyelitis and hallux varus occurred. The AOFAS score, VAS score, and the first metatarsophalangeal joint space after operation significantly improved when compared with those before operation, the AOFAS score and VAS score at 24 months after operation further improved when compared with those at 6 months after operation, and the differences were significant ( P<0.05). The change of VAS score in mild group was significantly better than that in moderate group ( P<0.05); but there was no significant difference in the changes of AOFAS score and the first metatarsophalangeal joint space between the two groups ( P>0.05). CONCLUSION Youngswick-Akin osteotomy for moderate valgus deformity with mild to moderate hallux rigidus can achieve good functional recovery, pain relief, and joint space improvement.

Chaihu Guizhi Decoction is an excellent prescription of ZHANG Zhongjing;however,nowadays the application of Chaihu Guizhi Decoction is primarily derived from the text.The xiang thinking is the source of traditional Chinese medicine thinking.Understanding Chaihu Guizhi Decoction from the xiang thinking,it is easy to perceive the true meaning of ZHANG Zhongjing,and grasp the location of the disease and the patient's overall qi,so as to make better use of this formula.This article discusses the understanding of Chaihu Guizhi Decoction from five perspectives:firstly,it gives an overview of the xiang thinking,pointing out the source and essential value of the xiang thinking;secondly,it analyses the disease position and the patient's qi of Chaihu Guizhi Decoction under the perspective of the xiang thinking as a whole;thirdly,it discusses the disease position and the patient's qi of the original text of Chaihu Guizhi Decoction from the xiang thinking;fourthly,it discusses how to understand the principle of formula formation and the main and minor parts of Chaihu Guizhi Decoction by xiang thinking;finally,it analyses the primary medicines in Chaihu Guizhi Decoction by using xiang thinking based on the records of Shennong Bencao Jing.Based on these five points,we hope to reveal the traditional Chinese medicine thinking behind Chaihu Guizhi Decoction,and provide new ideas for the clinical application of Chaihu Guizhi Decoction.

This article summarizes the unique viewpoints and experience application of the famous and veteran Chinese medicine practitioner,Professor Wang Xinzhi,in treating emotional diseases from the perspective of gallbladder theory.Based on the physiologi-cal functions and characteristics of the gallbladder in Chinese medicine,it is proposed that the"heart mind-gallbladder-viscera"axis dominates the generation and changes of emotions,and it is believed that gallbladder failure is the key pathogenesis of emotional disor-ders.The treatment of clinical syndromes should be based on the type of gallbladder,and emotional diseases can be divided into types of insufficient gallbladder qi,unfavorable Shaoyang,gallbladder and heat excess,timidity-deficiency,and heart-gallbladder indeci-sion,according to clinical manifestations;based on the basic principle of adjusting the functions of the heart,spleen,liver,gallblad-der,kidney and other organs,treatment methods such as tonifying the spleen and kidneys,increasing gallbladder qi,resolving Shaoy-ang,clearing gallbladder heat,warming yang and replenishing qi,calming the mind,resolving phlegm and removing blood stasis should be used,highlighting the joint treatment of the heart and the gallbladder,and the simultaneous regulation of the liver and gall-bladder,so that the mind can be at ease,the gallbladder can be decisive,and the emotions can be harmonious.

Objective:To compare and discuss the mid-to-long-term outcomes of mitral valve repair (MVP) versus biological mitral valve replacement (bMVR) in patients aged 60 years and above with rheumatic mitral valve disease.Methods:This is a retrospective cohort study. A total of 765 patients aged 60 years and older, diagnosed with rheumatic mitral valve disease and who underwent MVP or bMVR at Beijing Anzhen Hospital from January 2010 to January 2023, were retrospectively included. Among them, 186 were male and 579 were female, with an age of (66.1±4.5) years (range: 60 to 82 years). Patients were divided into two groups based on the surgical method: the mitral valve repair group (MVP group, n=256) and the bioprosthetic mitral valve replacement group (bMVR group, n=509). A 1∶1 propensity score matching was performed using a caliper value of 0.2 based on preoperative data. Paired sample t-tests, χ2 tests, or Fisher′s exact tests were used for intergroup comparisons. Kaplan-Meier method was employed to plot survival curves and valve-related reoperation rate curves for both groups before and after matching, and Log-rank tests were used to compare the mid-to long-term survival rates and valve-related reoperation rates between the two groups. Results:A total of 765 patients who completed follow-up were ultimately included, with a follow-up period ( M(IQR)) of 5.1(5.0) years (range: 1.0 to 12.9 years). After matching, each group consisted of 256 patients. The incidence of early postoperative atrial fibrillation (39.1% vs. 49.2%, χ2=4.95, P=0.026) and early mortality rates (2.0% vs. 6.2%, χ2=4.97, P=0.026) were lower in the MVP group. Unadjusted Kaplan-Meier analysis showed significantly higher 5-year and 10-year survival rates for the MVP group (92.54% vs. 83.02%, 86.22% vs. 70.19%, Log-rank: P=0.001). After adjustment with propensity scores, the Kaplan-Meier analysis still indicated higher 5-year and 10-year survival rates in the MVP group compared to the bMVR group (92.54% vs. 85.89%, 86.22% vs. 74.83%, Log-rank: P=0.024). There were no significant differences in the rates of valve-related reoperation between the two groups before and after matching (5-year and 10-year reoperation rates pre-matching: 1.75% vs. 0.57%, 5.39% vs. 7.54%, Log-rank: P=0.207; post-matching: 1.75% vs. 0, 5.39% vs. 9.27%, Log-rank: P=0.157). Conclusion:For patients aged 60 years and above with rheumatic mitral valve disease, mitral valve repair offers better mid-to-long-term survival compared to biological valve replacement.

Conclusion:For patients aged 60 years and above with rheumatic mitral valve disease, mitral valve repair offers better mid-to-long-term survival compared to biological valve replacement.

Objective:To explore the clinical safety and effectiveness of self-draining ureteral stent with thread in kidney transplant recipients in renal transplantation.Methods:This study is a prospective cohort clinical study in the Department of Urology of Peking University People's Hospital from November 2022 to January 2024.The ureteral stent with thread group,in which a 2-0 Mersilene suture of 20-30 cm was used at the bladder end of the ureteral stent during the operation.On the 9th day after the opera-tion,the suture attached to the end of the ureteral stent was expelled out of the urethral orifice with the urine when the catheter was removed.The ureteral stent could be removed along with the suture.As to the cystoscope group,a ureteral stent was routinely placed during kidney transplantation,and the ureteral stent was removed under local infiltration anesthesia through cystoscopy after the operation.The pain scores[numerical rating scale(NRS)-11]during catheter removal and the incidence of urinary tract in-fections were observed and compared between the two groups.t test was used to compare the pain scores of indwelling ureteral stents and ureteral stents removal between the two groups,and Chi-square test was used to compare the occurrence of urinary system complications within 3 months after operation between the two groups.P＜0.05 was considered statistically significant.Results:As of March 2024,all the re-cipients were followed up for an average of 6 months(3 to 12 months)postoperatively.A total of 46 kid-ney transplantation patients were included,with 21 in the ureteral stent with thread group and 25 in the cystoscope group.There were no statistically significant differences between the two groups in age distri-bution,male-to-female ratio,and deceased versus live donor grafts.Three months after renal transplanta-tion,there were 15 cases of urinary tract infection in the cystoscope group and 4 cases in the ureteral stent with thread group(P=0.007).No significant urinary fistula,wound infection,or ureteral stenosis occurred in either group.No stent-related complications,stent migration,or stone formation were ob-served.The postoperative bladder spasm symptom scores for indwelling ureteral stents in the cystoscope group and the ureteral stent with thread group were 4.4±2.5 and 4.6±2.4,respectively,with no sta-tistically significant difference(t=0.29,P=0.773).However,the pain scores during ureteral stent re-moval were 4.9±1.6 and 3.0±1.0 in the two groups,respectively,with a statistically significant diffe-rence(t=5.017,P＜0.001).The total costs of indwelling and removing ureteral stents in the cystosco-py group and the ureteral stent with thread group were 6 452.0(5 539.5,6 452.0)yuan and 3 225.0(3 225.0,3 225.0)yuan,respectively,and the difference was statistically significant(P＜0.001).Conclusion:Compared with the conventional transplanted kidney ureteral stent,the self-discharge ure-teral stent technique with sutures is simpler,has a shorter ureteral stent inlay time,reduces the symptoms of bladder spasms,significantly reduces the cost of catheterization,and has fewer postoperative urinary system complications.It is a worthy improved surgical method to be promoted.

Objective To observe the feasibility of 5.0T MR for cardiac imaging.Methods Three patients with heart diseases and 17 healthy volunteers were prospectively enrolled.Cardiac MR(CMR)cine sequence and black blood sequence imaging were performed using 5.0T and 3.0T MR scanner,respectively.The image quality and artifacts degrees were compared between 5.0T and 3.0T CMR images,and the consistency of left ventricular parameters obtained using 5.0T and 3.0T scanners was analyzed.Results No significant difference of image quality nor artifacts degrees was found between 5.0T and 3.0T CMR images(all P＞0.05).The left ventricular end diastolic volume(EDV),end systolic volume(ESV),ejection fraction(EF),stroke volume(SV)and end diastolic mass(EDM)derived from cine images acquired at different fields were in a good agreement(all ICC＞0.75,all P＜0.001).Conclusion 5.0T MR could be used for cardiac imaging,with image quality of cine and black blood sequences comparable to that of 3.0T MR.

Objective:To determine the motion detection uncertainty of the real-time CybeRay ? imaging system and patient intrafractional motion with thermoplastic mask-based immobilization. Methods:Real-time CybeRay ? imaging system was used for irradiation and treatment for head phantom and patients with brain tumors. All patients were immobilized with thermoplastic masks. Real-time imaging was delivered using kilovoltage projection images during radiotherapy. The detected patient motion data was collected from 5 head phantom measurements and 27 treatment fractions of 9 brain tumor patients admitted to Kaifeng Cancer Hospital. The accuracy and uncertainty of the motion monitoring system were determined. Results:The mean and standard deviation (SD) of the detected motion in the X, Y, and Z directions for phantom were (-0.02±0.41) mm, (-0.05±0.22) mm and (0.01±0.35) mm, respectively. The detected motion in the X, Y and Z directions for patents were (-0.13±0.48) mm, (-0.05±0.48) mm and (0.11±0.36) mm, respectively. After removing the motion detection uncertainty, the actual intrafractional motion of patients were (-0.11±0.25) mm, (0±0.43) mm and (0.10±0.08) mm in three directions, respectively. Conclusions:The uncertainty of real-time imaging-based motion monitoring system of CybeRay ? is less than 0.5 mm. It is feasible to apply thermoplastic masks for brain tumor patients in clinical practice, which can provide steady immobilization and limit the SD of patient intrafractional motion within 0.5 mm. Real-time imaging-based motion monitoring system of CybeRay ? is accurate for patient motion monitoring during frameless stereotactic radiosurgery/radiotherapy.
