To summarize rescuing and nursing experience of 3 ectopic pregnancy patients,suffering from severe toxicity caused by low-dose methotrexate(MTX)treatment.The key points include:constantly monitoring of patients for at least a week after MTX administration,and identifying MTX toxicity related symptoms as soon as possible;promptly establishing a multidisciplinary medical team to establish individualized rescue plans;quickly initiating the rescue therapy and implementing targeted fluid management to accelerate MTX excretion;intensifying protective isolation caring to prevent and control infection;applying refined safety management to prevent spontaneous bleeding;providing intensive caring of skin and mucosal toxicity symptoms to promote healing process;supplying individualized psychological counseling and support in time;strengthening the protection of the damaged organ.After emergent rescuing and intensive nursing,all 3 patients successfully recovered and were discharged from the hospital.

Objective:To analyze the types and characteristics of post-operative complications in colorectal cancer patients aged over 85 years undergoing laparoscopic surgery, and to summarize peri-operative management strategies.Methods:This was an observational study. Inclusion criteria: pathologically confirmed adenocarcinoma; tumor located in ileocecum, ascending colon, transverse colon, descending colon, sigmoid colon, or rectum; undergoing laparoscopic radical resection for colorectal cancer; complete clinical data. Exclusion criteria included distant metastasis, synchronous resection of multiple primary cancers, simultaneous liver metastasis surgery, and follow-up duration <1 month. A retrospective analysis was conducted on 191 patients of colorectal cancer patients aged over 85 years who underwent laparoscopic radical surgery in the General Surgery Department at Peking Union Medical College Hospital from January 2019 to January 2024. Among 191 patients, 107 patients (56.0%) had colon cancer and 84 (44.0%) rectal cancer. All patients received "home-based prehabilitation" and post-operative "enhanced recovery after surgery" protocols. Patient characteristics, peri-operative complication types, treatments, and outcomes were analyzed.Results:Post-operative complications occurred in 97 patients (50.8%), including 53 colon cancer patients (54.6%) and 44 rectal cancer patients (45.4%). Comorbidities existed in 88 patients (90.7%), with 93 patients (95.9%) classified as ASA II-III pre-operatively and 86 (88.7%) having nutritional risks. Surgical procedures included Dixon procedure (38 patients, 39.2%), right hemicolectomy (33 patients, 34.0%), sigmoidectomy (10 patients, 10.3%), and 17 patients (17.5%) received prophylactic stomas. Complication types comprised non-anastomotic infections (38 patients, 19.9%), intestinal flora disorder (26 patients, 13.6%), anastomotic/wound/stoma-related complications (16 patients, 8.4%), thrombotic/hemorrhagic events (6 patients, 3.1%), and others (11 patients, 5.8%). By Clavien-Dindo classification: Grade I (12 patients, 6.3%), Grade II (69 patients, 36.1%), Grade III (12 patients, 6.3%), and Grade IV (4 patients, 2.1%). Except for 5 patients (2.6%) requiring unplanned re-operation, all complications resolved with conservative treatment. The median duration of post-operative hospitalization was 9.5 days (7–13).Conclusion:Non-anastomotic infections and intestinal flora disorder constitute predominant complications after laparoscopic surgery in colorectal cancer patients aged over 85 years, mostly manageable with conservative treatment. Strengthened peri-operative management incorporating pre-operative prehabilitation and post-operative enhanced recovery after surgery protocols is crucial for patients aged over 85 years.

Objective:To evaluate the clinical features and risk factors of anastomotic leakage (AL) in patients with locally advanced rectal cancer (LARC) receiving neoadjuvant chemoradiotherapy (nCRT) followed by laparoscopic radical resection and proctocol ostomy.Method:Clinicla data of LARC patients receiving neoadjuvant chemoradiotherapy followed by laparoscopic radical resection and proctocol ostomy admitted to Peking Union Medical College Hospital between Jan 2019 and Oct 2023 was enrolled. According to the occurrence of AL, patients were divided into AL group and non-AL group.Results:After propersity matching score(PSM), there were 40 patients (33.4%) and 80 patients (66.6%) in the AL and non-AL group, respectively. The first-onset symptoms of AL were abnormal character and color of the drainage (23 cases, 57.5%) and fever (14 cases, 35.0%). About 82.5% of the AL were graded as B,and all 36 patients (90.0%) were managed consveratively by fully drainage anti-infection therapy. Logistic regression analysis indicated that tumor circumferential range more than 1/2 cycle ( OR=5.95, 95% CI:2.12-1.67, P=0.004), male ( OR=4.28, 95% CI:1.22-15.00, P=0.023) and high-ligation of Inferior mesenteric artery ( OR=8.08, 95% CI:1.86-37.78, P=0.006) were independent risk factors of AL. Conclusions:In this series, grade-B AL ranks the top of the incidence, and all were cured by conservative therapy. Special attention should be paid to those patients with the characteristics of male, tumor circumferential range more than 1/2 cycle, and high-ligation of inferior mesenteric artery.

Objective:To investigate the complications, along with their diagnosis and management, that follow local excision for rectal cancer after neoadjuvant therapy.Methods:The clinical data of 53 patients with rectal cancer who underwent local resection after neoadjuvant treatment in Peking Union Medical College Hospital from January, 2010 to December, 2024 were retrospectively collected for this descriptive case series study. Indications for local resection were: (1) age ≥ 18 years; (2) American Society of Anesthesiologists (ASA) classification I-III; (3) pathologically confirmed rectal adenocarcinoma; (4) distance from the lower edge of the tumor to the anal edge of less than 8 cm; and (5) use of preoperative neoadjuvant therapy. Contraindications of local resection were: (1) multiple primary colorectal cancer and (2) intestinal obstruction, intestinal perforation, or and gastrointestinal bleeding that required emergency surgery. There were 36 males and 17 females, and the median age was 62 (26-85) years. After neoadjuvant therapy, the median distance from the tumor to the anal margin was 4.5 (range, 2.2-6.9) cm. The main outcome measures included: surgical details, pathological findings, postoperative complications, anorectal function, and oncological outcomes (recurrence and survival).Results:Surgical methods included transanal endoscopic microsurgery (TEM) in 47 cases, transanal minimally invasive surgery (TAMIS) in 3 cases, and traditional transanal local resection in 3 cases. Of the 53 patients, 29 (54.7%) had pathological complete response (pCR), namely pT0 stage; 8 cases were pT1, 15 cases were pT2, and 1 case was pT3. Twenty-four cases (45.3%) had 33 complications. Clavien-Dindo grade I-II accounted for 97.0% (32/33), including 14 cases (26.4%) of wound dehiscence. Low anterior resection syndrome (LARS) occurred in 7 cases (13.2%), including 5 minor cases and 2 major cases. Postoperative fever occurred in 7 cases (13.2%); urinary retention occurred in 3 cases (5.7%); and diarrhea occurred in 1 case (1.9%). Clavien Dindo grade III was observed in only 3.0% (1/33) of patients, which was a rectovaginal fistula. Among the 14 patients with wound dehiscence, 7 cases only suffered anal pain and were cured after symptomatic analgesic treatment. Five cases suffered anal pain with hematochezia but improved after treatment with essential diet, hemostasis, intravenous antibiotics, pain relief, and sitz bath. Two cases of secondary perianal infection were treated with intravenous antibiotics, local drainage, parenteral nutrition support, and symptomatic treatment, and the wounds healed within 2 months. One patient with rectovaginal fistula underwent transverse colostomy. After six months, the fistula healed and stoma reversal was performed. Seven patients with LARS received anal lifting exercise and defecation reflex training, and anal function recovered to the preoperative level after 1 year. Other complications improved after symptomatic treatment, pain relief, or catheter replacement. The median follow-up time was 60 months. Local recurrence occurred in 4 patients (7.5%) and distant metastasis occurred in 12 patients (22.6%). Seven patients (13.2%) died. The 5-year disease-free survival rate was 75.5%, and the 5-year overall survival rate was 86.8%.Conclusions:Local excision for rectal cancer following neoadjuvant therapy has a high incidence of complications, mainly wound-related, due to the decline of rectal wound healing ability after radiotherapy. However, most of the complications were relieved after symptomatic treatment, and the risk was controllable.

Background and Aims:For patients with mid-to-low rectal cancer who achieve clinical complete response(cCR)or near-cCR after neoadjuvant chemoradiotherapy(nCRT),the key concern for both clinicians and patients is how to preserve anal function as much as possible without significantly compromising oncological outcomes.This study was performed to evaluate the safety and feasibility of local excision as an anus-preserving approach in rectal cancer patients with cCR or near-cCR.Methods:A retrospective analysis was conducted on 51 patients with mid-to-low rectal cancer who underwent local resection after achieving cCR or near-cCR following nCRT at Peking Union Medical College Hospital,Chinese Academy of Medical Sciences,between March 2014 and July 2023.The clinical characteristics,imaging and pathological findings,surgical outcomes,as well as oncological and functional results were reviewed.Results:Among the 51 patients,34 were male and 17 were female,with a mean age of 61±14 years.Pre-nCRT imaging staging showed:cT1-2N0 in 12 cases(23.5％),cT3N0 in 13 cases(25.5％),cT1-3N0-1 in 19 cases(37.4％),and cT1-3N2 in 7 cases(13.7％).The average tumor distance from the anal verge was(4.5±1.1)cm.After achieving cCR or near-cCR following nCRT,all patients underwent local resection:40 cases(78.4％)underwent transanal endoscopic microsurgery(TEM),7 cases(13.7％)underwent transanal minimally invasive surgery(TAMIS),and 4 cases(7.8％)underwent conventional transanal local excision.The postoperative complication rate was 27.5％(14/51),with 71.4％classified as Clavien-Dindo grade Ⅰ.Postoperative histopathology showed ypT0 in 26 cases(51.0％),ypT1 in 8 cases(15.7％),ypT2 in 16 cases(31.4％),and ypT3 in 1 case(2.0％).The concordance rate between pathological results and preoperative imaging was 54.9％.Over a median follow-up of 60 months(range:34-79),there were 4 cases(7.8％)of local recurrence,12 cases(23.5％)of distant metastasis,and 5 cancer-related deaths(9.8％).Six months postoperatively,both the Wexner score and the low anterior resection syndrome(LARS)score significantly improved compared to post-nCRT values[Wexner:1(0-2)vs.2(1-5);LARS:3.3±5.75 vs.4.3±6.86;both P＜0.01].Conclusion:For patients with mid-to-low rectal cancer who achieve cCR or near-cCR after nCRT,local en bloc resection of the bowel wall lesions enables accurate assessment of residual tumor status and facilitates personalized subsequent treatment,potentially sparing some patients from radical surgery.Local resection can be a viable anus-preserving option for patients who are unfit for or strongly averse to radical resection.However,local excision cannot replace radical surgery,and its precise indications warrant further investigation.

Objective:To detect the association of tumor circumferential involvement range (CIR) with neoadjuvant chemoradiotherapy (NCRT) efficacy and long-term survival outcomes in locally advanced rectal cancer (LARC) patients.Methods:Clinical data of 451 patients admitted to our hospital from January, 2018 to January, 2022 were retrospectively collected. According to the CIRs as determined by rectal magnetic resonance imaging, patients were divided into the High group (≥2/3 cycle, 270 patients) and the Low group (＜2/3 cycle, 181 patients). The primary outcome was three-year disease-free survival. The baseline characteristics, pathological features, and survival outcomes were compared.Results:Compared to patients in the Low group, patients in the High group exhibited significantly larger tumor vertical diameters [(4.7±1.7) vs. (3.6±1.4)cm, P＜0.001], higher rates of mrT4 stage (37.8% vs. 13.2%, P＜0.001), and higher rates of positive mesorectal fascia (54.1% vs. 29.8%, P＜0.001) and extramural vascular invasion (55.6% vs. 38.1%, P＜0.001). Patients in the High group were mainly pT3-4 stages (46.7% vs. 30.9%, P=0.002), with significantly lower rates of pathological complete response (22.2% vs. 33.1%, P=0.010) , poorer tumor regression grades (48.9% vs. 60.8%, P=0.013), and higher rates of positive peripheral nerve invasion (11.5% vs. 5.5%, P=0.031), as compared to patients in the Low group. The median follow-up time was 40 months. About 11 (2.4%) and 48 patients (10.6%) experienced tumor local recurrence and distant metastasis, respectively. The recurrence rates were 2.2% and 2.6%, and the distant metastasis rates were 7.7% and 12.6%, respectively, in the Low group and the High group, with no statistical significance ( P=0.957, P=0.096). The three-year disease-free survival in the High group was significantly lower than that in the Low group (84.4% vs. 92.4%, P=0.014). Conclusions:The CIR is closely related to tumor burden, which can judge tumor response to NCRT, and is negatively related to survival prognosis. For patients who have more than a 2/3 cycle of CIR, intensified or consolidated treatments may be required to improve survival outcomes.

Objective:The aim was to analyze key indicators for the diagnosis and treatment of chronic hepatitis B（CHB），including virus detection rate，standardized treatment rate，and loss to follow-up rate，in order to provide a basis for optimizing diagnosis and treatment plans，improve the diagnosis and treatment level of CHB，and improve patient prognosis.Methods:Patients with CHB admitted to the Guangzhou Eighth People′s Hospital Affiliated to Guangzhou Medical University from January 2024 to January 2025 were enrolled. The datas were collected and organized using Excel. Statistical analysis was conducted using SPSS 26.0 software，with a focus on evaluating core indicators such as virus detection rate，standardized treatment rate，and loss to follow-up rate.Results:The positive rate of hepatitis B surface antigen（HBsAg）in non-specific patients was 28.95%，the antiviral treatment rate in specialized patients was 90.78%，and the standardized antiviral drug conversion treatment rate in low-level viremia（LLV）patients was 61.45%. The standardized antiviral drug conversion treatment rates for high-risk patients with combined kidney/bone injuries were 72.75% and 74.40%，respectively. The overall dropout rate was 10.47%，with a dropout rate of 13.80% for LLV patients.Conclusions:The antiviral treatment coverage rates in CHB patients were over 90%，but in certain groups（such as LLV patients and those with kidney or bone injuries），the standardized treatment rates were still low and loss to follow-up rates were high，suggesting the need to improve HBV screening，treatment for special populations，and patient adherence.

Objective To analyze the current quality of treatment for hospitalized cancer patients in Bei-jing,identify major issues in treatment practices,and propose improvements.Methods Nine hospitals in Beijing were selected for examination.Expert on-site interviews and medical record sampling were conducted.The"Bei-jing Cancer Diagnosis and Treatment Quality Control Checklist"was used to assess the hardware,management,anti-cancer drug therapy,radiation therapy,and surgical treatment during cancer treatment at these hospitals from January to October 2023.The relevant problems were analyzed.Results Among the nine hospitals,two(22.2％)were equipped with laminar flow rooms,and three(33.3％)had intravenous drug preparation centers.In terms of institutional management,seven hospitals(77.8％)had standardized anti-cancer drug prescription authority management,eight(88.9％)had complete emergency plans,and five(55.6％)had oncology specialist pharmacists.Regarding anti-cancer drug therapy,the areas with higher completion rates included pathology diag-nosis support(97.6％),routine pre-treatment examinations(96.3％),adverse reaction evaluation(92.7％),discharge summaries(95.1％),and admission records(91.5％).However,the accuracy of tumor staging before treatment(70.7％)and the evaluation of therapeutic efficacy after drug treatment(76.9％)needed improvement.The oncology specialty significantly outperformed the non-oncology specialty in terms of the accuracy rate of TNM staging(86.0％vs.46.9％,P＜0.001),the completeness of informed consent forms(100％vs.68.8％,P＜0.001),the completeness of drug indication evaluation(96.0％vs.78.1％,P=0.025),the completeness of admission medical history records(98.0％vs.81.3％,P=0.008),the rationality of drug dosage(96.0％vs.75.0％,P=0.005),the rationality of drug infusion time(100％vs.62.5％,P＜0.001),and the rationality of the order of drug infusion(100％vs.87.5％,P=0.010).Although the quality of radiation therapy was high,the subsequent evaluation of therapeutic efficacy(39.3％)requires enhancement.In surgical treatment,the preoper-ative pathology diagnosis support rate(78.1％)and the accuracy of tumor staging(37.5％)were relatively low,indicating issues with incomplete preoperative evaluation and the absence of multidisciplinary discussions.Conclusions There remains significant room for improvement in the quality of cancer treatment in China.It is recommended to standardize tumor staging assessment processes,strengthen entry assessments for non-oncology departments,promote the implementation of multidisciplinary treatment models,and establish a multi-department collaborative management model.Continuous monitoring of cancer diagnosis and treatment quality indicators is es-sential to promote ongoing improvements in cancer treatment quality.

Objective:To compare the clinical outcomes of reconstruction of oral and maxillofacial soft tissue defects using superficial circumflex iliac artery perforator flap （SCIA PF） and radial forearm free flap （RFF）. Methods:A retrospective analysis was conducted on 90 patients with head, neck, and maxillofacial tumors who were treated in our department from June 2019 to January 2024. Patients were divided into two groups based on the surgical method used: the SCIA group（n=45）, who underwent reconstruction with SCIA PF, and the RFF group（n=45）, who received RFF reconstruction. Six months postoperatively, clinical efficacy was evaluated by comparing flap swelling, flap survival rate, and patient satisfaction. Oral function was assessed using standardized scoring systems before surgery, at 1 week, 3 months, and 6 months post-surgery. Hemorheological parameters, including high-shear viscosity（shear rate 200/s）, low-shear viscosity（shear rate 30/s）, plasma viscosity, erythrocyte aggregation index, and erythrocyte sedimentation rate（ESR）, were also measured at each time point. Results:Compared with the RFF group, the SCIA group showed significantly larger flap size, longer flap harvesting and reconstruction times, earlier nasogastric tube removal and oral intake initiation, higher scores in all aspects of oral function, reduced flap edema and faster resolution, higher flap survival rates, and greater overall satisfaction （all P<0.05）. During the follow-up period （preoperative, 1 week, 3 months, and 6 months post-surgery）, hemorheological indices including high-and low-shear viscosity, plasma viscosity, erythrocyte aggregation index, and ESR progressively decreased in the SCIA group （P<0.05）. In the RFF group, these parameters improved significantly by 6 months postoperatively compared with preoperatively and 1-week postoperatively, with a notable decrease in erythrocyte aggregation index at 6 months （P<0.05）. Conclusion:Compared with RFF, SCIA PF provides larger flaps, better functional recovery, higher patient satisfaction, improved flap survival, fewer complications, and more favorable hemorheological profiles following reconstructive surgery for oral and maxillofacial defects.
