Skeletal class Ⅱ malocclusion is characterized by maxillary protrusion,mandibular retrognathia,or a combination of both,and often accompanied by vertical dimensional discrepancies;treatment is complex,and combined orthodontic-orthognathic surgery is needed for the adult patients.Clear aligner therapy has gradually been applied in complex orthodontic cases.However,limited cases have been reported domestically and internationally regarding the application of clear aligner therapy combined with orthognathic surgery.This article presented a case of a patient with skeletal class Ⅱ high-angle malocclusion treated with the combined therapy and analyzed the clinical efficacy of the treatment appraoch to provide reference for the clinical practice.Extraction of impacted wisdom teeth 18,28,38,and 48,as well as orthodontic teeth 15,25,34,and 44,was performed in stages before orthodontic treatment.Clear aligner therapy was used for preoperative orthodontics.In sagittal plane,a super-complete class Ⅱ canine and molar relationship and a 13-14 mm overjet of the anterior teeth were established.The maxillary and mandibular arch morphology was matched horizontally.The orthognathic surgery included maxillary LeFort Ⅰ osteotomy,bilateral sagittal split ramus osteotomy(BSSRO)and chinplasty.Fine occlusal adjustment was conducted after operation.After treatment,the skeletal relationship between upper and lower jaw was corrected to normal;subspinale-nasion-supramental angle(ANB)was improved from 12.3° to 4.7°;the patient established the class Ⅰ canine and molar relationship,with normal overjet and overbite;root parallelism was good and there was no obvious root resorption;the facial soft tissue profile was significantly improved,and nasion-subnasale-pogonion angle(N-Sn-Pg)was improved from 143.9° to 162.8°.The curative effect was stable 1 year after operation.Clear aligner therapy can efficiently complete combined orthodontic and orthodontic surgery in the complex cases.Compared with the fixed appliance,it is more beneficial to the patients'need for beauty and the maintenance of periodontal health.

Peptide receptor radionuclide therapy (PRRT) with radiolabeled SSTR2 agonists is a treatment option that is highly effective in controlling metastatic and progressive neuroendocrine tumors (NETs). Previous studies have shown that an SSTR2 agonist combined with albumin binding moiety Evans blue (denoted as ¹⁷⁷Lu-EB-TATE) is characterized by a higher tumor uptake and residence time in preclinical models and in patients with metastatic NETs. This study aimed to enhance the in vivo stability, pharmacokinetics, and pharmacodynamics of ¹⁷⁷Lu-EB-TATE by replacing the maleimide-thiol group with a polyethylene glycol chain, resulting in a novel EB conjugated SSTR2-targeting radiopharmaceutical, ¹⁷⁷Lu-LNC1010, for PRRT. In preclinical studies, ¹⁷⁷Lu-LNC1010 exhibited good stability and SSTR2-binding affinity in AR42J tumor cells and enhanced uptake and prolonged retention in AR42J tumor xenografts. Thereafter, we presented the first-in-human dose escalation study of ¹⁷⁷Lu-LNC1010 in patients with advanced/metastatic NETs. ¹⁷⁷Lu-LNC1010 was well-tolerated by all patients, with minor adverse effects, and exhibited significant uptake and prolonged retention in tumor lesions, with higher tumor radiation doses than those of ¹⁷⁷Lu-EB-TATE. Preliminary PRRT efficacy results showed an 83% disease control rate and a 42% overall response rate after two ¹⁷⁷Lu-LNC1010 treatment cycles. These encouraging findings warrant further investigations through multicenter, prospective, and randomized controlled trials.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

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 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 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:To explore the application value of selective transurethral plasma kinetic resection of the prostate (PKRP) and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of diabetes benign prostatic hyperplasia (BPH).Methods:A total of 114 patients with diabetes BPH diagnosed and treated in Lanxi People′s Hospital from September 2020 to September 2023 were retrospectively selected and divided into resection group and enunciation group according to the operation method, with 57 cases in each group. The resection group received selective PKRP and the enucleation group received HoLEP. Preoperative and postoperative stress response indexes were compared between the two groups, as well as urodynamics indexes and complications before and 3 months after surgery.Results:The quality of prostatectomy in the enucleation group was higher than that in the resection group : (39.68 ± 3.02) g vs. (30.25 ± 2.84) g; the operation time, intraoperative blood loss, bladder irrigation time and hospital stay in the enucleation group were lower than those in the resection group: (63.84 ± 5.44) min vs. (72.58 ± 11.33) min, (62.38 ± 15.84) ml vs. (89.54 ± 17.91) ml, (1.84 ± 0.71) d vs. (2.35 ± 0.80) d, (4.98 ± 1.16) d vs.(5.64 ± 1.05) d, there were statistical differences ( P<0.05). The levels of serum cortisol (COR) and norepinephrine (NE) in the enucleation group at 1, 3 d after surgery were lower than those in the excision group [1 d after surgery: (279.76 ± 17.82) ng/L vs. (289.51 ± 18.37) ng/L, (287.44 ± 26.51) ng/L vs. (300.47 ± 28.35) ng/L; 3 d after surgery: (236.58 ± 15.98) ng/L vs. (247.46 ± 16.47) ng/L, (269.13 ± 23.51) ng/L vs. (278.76 ± 25.62) ng/L, there were statistical differences ( P<0.05). Three months after surgery, the maximum urine flow rate in the enucleation group was higher than that in the excision group : (21.51 ± 3.82) ml/s vs. (18.74 ± 4.17) ml/s, and the residual urine volume (RUV) was lower than that in the excision group : (8.47 ± 3.06) ml vs. (10.25 ± 2.43) ml, there were statistical differences ( P<0.05). There was no significant difference in the incidence of urethral stricture and urinary incontinence between the two groups ( P>0.05). Conclusions:HoLEP for the treatment of diabetes BPH can reduce stress response, promote disease recovery, improve urodynamics, and has a safety comparable to that of selective PKRP.
