This paper summarizes the experience of professor LIU Shangyi in differentiating and treating rectal carcinoma from the perspective of "treating ulcers as tumors". It is believed that the manifestations of rectal cancer， such as anal itching， cauliflower-like or ulcerative tumors， and bloody stools， are similar to external skin itching， skin ulceration， swelling， and skin bleeding. Therefore， the treatment principles of sores and ulcers department can be applied to treat tumors. Following the diagnostic and treatment approach of dermatology regarding the clinical typical symptoms， for anal itching， the main treatment is to dispel wind and remove dampness， clear heat to relieve itching， using "skin medicinals" such as Difuzi （Fructus Kochiae） and Baixianpi （Cortex Dictamni）， as well as wind medicinals such as Shengma （Rhizoma Cimicifugae） and Fangfeng （Radix Saposhnikoviae）. For constipation， the method of clearing heat and resolving toxins， unblocking the bowels and discharging heat can be used， commonly using Baitouweng （Radix Pulsatillae）， Donglingcao （Herba Rabdosiae Rubescentis） and Dahuang （Radix et Rhizoma Rhei）. In terms of mucosal ulcers， it is critical to differentiate between yin and yang； the treatment of yang ulcers should focus on clearing heat and resolving toxins， commonly using modified Xianfang Huoming Beverage （仙方活命饮）； for yin ulcers， emphasis should be placed on removing dampness and resolving phlegm， commonly with modified Yiyi Fuzi Baijiang Powder （薏苡附子败酱散）. For bloody stool， differentiation is made between deficiency and excess， with the use of Diyu （Radix Sanguisorbae） and Huaihua （Flos Sophorae） for excess syndrome to cool and stop blee-ding， and both herbs dry-fried until charred combined with liver-tonifying medicinals for deficiency syndrome

Objective:To investigate the efficacy of rigid ureteroscopic laser lithotripsy combined with N-trap(RULL+N-trap),which is scoop-shaped,in the treatment of ureteral stones with a maximum diameter ≥1.5 cm.Methods:This retrospective cohort study included patients diagnosed with ureteral calculi who underwent rigid ureteroscopic lithotripsy(RULL)combined with N-Trap stone entrapment system at the Department of Urology,Peking University Third Hospital,by the same surgical team between June 2021 and September 2024.A total of 364 patients were initially enrolled.After excluding 21 patients due to missing critical outcome variables,two distinct cohorts were established:38 patients with ureteral stones measuring ≥1.5 cm in maximum diameter,and 305 patients with stones＜1.5 cm in maximum diameter.To minimize selection bias and control for confounding variables,propensity score matching(PSM)was employed.This resulted in two well-balanced groups:31 patients with stones 1.5 cm in maximum diameter and 31 patients with stones＜1.5 cm in maximum diameter,matched on baseline demographic and clinical characteristics.The primary outcomes assessed between the two groups included stone clearance.Secondary outcomes included changes in renal function indicators,specifically serum creatinine(SCr)and estimated glomerular filtration rate(GFR),and other factors like postopera-tive hospital stay and operative time.Results:In the matched cohort,the patients with stones ≥1.5 cm in maximum diameter had significantly longer operative time compared with those with smaller stones:(85.8±28.8)min vs.(62.4±24.6)min(P＜0.05).Postoperative length of hospital stay showed no significant difference:(2.26±1.79)d vs.(2.03±0.80)d(P＞0.05).The stone clearance on postoperative day one was 90.3％in the study group vs.100.0％in the control group(P＞0.05).One month postoperatively,the stone clearance was 93.5％vs.100.0％,respectively(P＞0.05).Changes in SCr were(-6.58±16.10)μmol/L vs.(-13.70±12.50)μmol/L,and changes in GFR were(5.92±14.90)mL/(min·1.73 m2)vs.(7.47±11.20)m L/(min·1.73 m2),with no statistically significant differences observed between the two groups for either renal function marker(P＞0.05).Conclusion:Ureteroscopic lithotripsy combined with N-trap is an optional method for treating ureteral stones with a maximum diameter ≥1.5 cm.The overall therapeutic efficacy is comparable,with the added benefit of significantly reducing the economic burden on patients.

Objective:To investigate the intervention effect of dance therapy on the psychological symptoms and psychological craving in methamphetamine-dependent women.Methods:A total of 60 methamphetamine de-pendents in a women's drug rehabilitation center were divided into intervention group and control group(1 person dropped out).The intervention group was trained for 8 dance movements,during which the control group did not in-tervene.The Zhang Tuoji and Chen Huichang's Temperament Scale,Symptom Self-Rating Scale(SCL-90)and Amphetamine Craving Scale(DSQ)were used to evaluate the temperament type,psychological symptoms and psy-chological craving.Results:The differences of SCL-90 depression and anxiety scores(post-intervention score-base-line score)and DSQ total scores were higher in the intervention group than in the control group(Ps＜0.05).The choleric temperament scores were negatively correlated with the differences of DSQ total scores(r=-0.45,P＜0.05),and the melancholic temperament scores were positively correlated with the differences of SCL-90 hostility dimension scores(r=0.41,P＜0.05).Conclusion:Dance therapy could improve the psychological symptoms and psychological craving of women dependent on methamphetamine,with varying effects across different temperament types.

Objective To observe the expression and trends of tight junction proteins Occludin and zonula occlu-den-1(ZO-1)in blood-brain barrier(BBB)of rats with traumatic brain injury(TBI),and to explore the interven-tion effect of cannabidiol(CBD)on the BBB.Methods The TBI model of rat was prepared by modified"Feeney free fall method"and randomly divided into three groups:the sham-operated group(Sham group),the model group(TBI+vehicle group)and the CBD intervention group(TBI+CBD group),with 24 rats in each group.Each group was subdivided into six time points:8 h,1,2,3,5 and 7 d after injury.The expression of Occludin and ZO-1,which are closely related to the permeability of BBB,was detected by immunohistochemistry,immuno-fluorescence staining and Western blot at different points.The permeability of BBB was detected by sodium fluores-cein assay.Results The results of immunohistochemistry showed that compared with Sham group,the positive ex-pression of Occludin and ZO-1 decreased with time after brain trauma(P<0.05),and both reached the lowest level at 2 d.The expression levels of Occludin and ZO-1 were up-regulated after 1 d of CBD intervention(P<0.05).Immunofluorescence staining showed a similar trend to Western blot results,with Occludin and ZO-1 fluo-rescence expression intensity and protein expression reduced after TBI compared with Sham group(P<0.05).And the expression levels of Occludin and ZO-1 were up-regulated after 2 d of CBD intervention(P<0.05).The results of fluorescein sodium experiment showed that the BBB integrity of brain tissue was destroyed after TBI,and the permeability increased after TBI(P<0.01).The permeability of BBB decreased after CBD intervention(P<0.05).Conclusion The expression of tight junction proteins Occludin and ZO-1 decreases after TBI,and the permeability of BBB is disrupted,and CBD intervention reverses the disruption of the BBB by TBI.

Objective:Explore the feasibility and advantages of using proximal and distal ends of thoracodosal artery and vein as recipient vessels in deep inferior epigastric perforator flap immediate breast reconstruction.Methods:The clinical data of patients who underwent breast reconstruction surgery using the proximal and distal ends of the thoracodorsal vein as recipient vessels at the Department of Breast and Thyroid Surgery of the Second Affiliated Hospital of Hainan Medical University from March 2022 to June 2023 were analyzed retrospectively. Preoperative examinations included thoracoabdominal angiography and color Doppler ultrasonic localization of the main trunk and perforators of the inferior epigastric vessels. The procedure began with mastectomy and axillary lymph node dissection, followed by the isolation of bilateral perforators and the main trunk of the abdominal flap. The main trunks of the bilateral inferior epigastric arteries were then transected, and their vascular pedicles exposed and anastomosed respectively to the proximal and distal ends of the thoracodorsal artery and vein. Both arteries and veins were joined end-to-end. The flap after trimming and reconstruction was then implanted into the cavity left after mastectomy through the incision. Breast positioning was performed with the patient in a knee-bent and hip-flexed position. After adjusting the shape of the reconstructed breast. The donor site was closed, the umbilicus was reconstructed, drainage tubes were placed, and the breast incision was closed. Postoperative follow-up monitored complications associated with the flap and patient satisfaction with the breast reconstruction, utilizing a self-assessment method.Results:Four female patients were included, aged (46.0±6.5) years, ranging from 37 to 52 years. All four patients had bilateral vascular pedicles in the donor area, with three patients having thoracodorsal vessels at the distal and proximal ends as recipient vessels, and one patient having anterior serratus branch of the thoracodorsal vessels at the distal and proximal ends. All drainage tubes were removed within 7 to 10 days after surgery. Patients were discharged. Follow-up period ranged from 1 to 15 months, averaging 6 months. The patients recovered well postoperatively, with no flap-related complications occurring. All four patients were satisfied with the result of the reconstruction.Conclusion:The simultaneous application of the proximal and distal ends of the thoracodorsal artery and vein can ensure the safety of flap survival while reducing damage to the ribs and intercostal muscles, achieving better aesthetic result.

Objective To investigate the serological and molecular characteristics of twenty blood samples carrying ABO?AW.37 allele and to analyze ABO allelic enhancement.Methods The ABO phenotype of the twenty samples was de-termined by serological methods and the genotype of 1-7 ABO exons was analyzed by Sanger sequencing.Results Sequen-cing analysis showed that all twenty samples contained a c.940A>G(p.Lys314Glu)mutation of A allele,which was defined as ABO?AW.37.When ABO?AW.37 and B alleles were inherited simultaneously in 9 cases,in forward typing anti-A anti-bodies all agglutinated and the serological phenotype was Aw B.Among the 11 cases with ABO?AW.37 and O alleles inherited simultaneously,there was no agglutination of anti-A in forward typing.For absorption and elution tests,5 cases were weakly positive and the serological phenotype was Ael,while 6 cases were negative for absorption and elution tests and the serologi-cal phenotype was O type.Conclusion Allelic enhancement occured when both ABO?AW.37 allele and B allele were in-herited simultaneously.When ABO? AW.37 was inherited simultaneously with O allele,the serological phenotype was Aelor O type and attention should be paid to blood type identification.
