This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective:To investigate a surgical method and clinical effect on reconstruction of infective ulcer and soft tissue defects in dorsal fingers of the elderly patients with free perforator flap of peroneal artery.Methods:From March 2016 to June 2022, 13 elderly patients with infective ulcer and soft tissue defects in dorsal fingers were reconstructed with free perforator flaps of peroneal artery. The patients were 65-70 years with an average age of 66.5 years. Cause of infection: 10 ulceration and soft tissue defects were caused by diabetes and 3 by injury. Seven infective ulceration and soft tissue defects were in dorsal index fingers, 3 in dorsal middle fingers and 3 in dorsal ring fingers with the size of soft tissue defects at 2.0 cm×4.5 cm-2.0 cm×5.5 cm with an exposure of tendon and phalange. The donor site of the flaps was of contralateral calf and the flaps were 2.5 cm×5.0 cm-2.5 cm×6.0 cm in size. All donor sites were sutured directly. All patients were included in the postoperative follow-up at outpatient clinic to observe the appearance and sensation of the flap as well as finger movement.Results:All flaps survived and all wounds achieved stage I healing, without recurrence of infection. Twelve patients had the postoperative follow-up for 12 to 27 months, with an average of 21.6 months. There were satisfactory appearance of flaps and the function of fingers. Sensation of flaps recovered to S 2 in 5 patients and S 3 in 7 patients. The recovery of hand function was evaluated according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, with 8 hands in excellent and 4 in good. Conclusion:The free perforator flap of peroneal artery has advantages of constant vascular anatomy, reliable blood supply, moderate thickness and direct closure of donor site. It is a useful clinical method in reconstruction of infective ulcer and soft tissue defects in dorsal fingers of the elderly patients.

【Objective】 To explore the diagnosis, treatment, prognosis and long-term follow-up of urogenital solitary fibrous tumor (SFT) and to differentiate the characteristics between benign and malignant SFT. 【Methods】 Clinical data of 20 patients with urogenital SFT treated in our hospital during Jan.2004 and Aug.2021 were respectively analyzed, including the general characteristics, clinical symptoms, imaging results, treatment methods, pathological results, and long-term follow-up results. 【Results】 Of the 20 cases, 9 cases had tumor in kidney, 7 in pelvic cavity, 3 in bladder and 1 in prostate.Six patients showed non-specific clinical symptoms, including lower extremity weakness, urodynia, dysuria, frequent urination with changes in stool habits, low back pain, and abdominal wall mass with abdominal pain, and the other 14 cases were asymptomatic.The median diameter of SFT was 5.2 cm (range:1.7-15.0 cm).All patients received surgical treatment, including robotic-assisted surgery in 8 cases, open surgery in 5 cases, laparoscopic surgery in 5 cases, and transurethral resection of tumor in 2 cases.CT plain scan showed high, low and mixed density soft tissue masses, and enhanced CT showed enhanced results.Pathology results revealed frequent nuclear divisions, morphological variations and necrosis in malignant SFT, which had higher expression of Ki-67 than benign SFT.The results of the modified Demicco prognostic risk stratification model showed that all malignant SFT cases were at intermediate risk. The DFS of the SFT radical tumor resection group was slightly longer than that of the simple tumor resection group but the difference was not statistically significant (P=0.203). 【Conclusion】 Markers such as CD34, Bcl2, STAT6 and CD99 are used to diagnose SFT, while Ki-67 and tumor necrosis are used to differentiate benign and malignant SFT.The modified Demicco prognostic risk stratification model plays an important role in predicting the prognosis of SFT.Surgical resection is the most common treatment with excellent prognosis.In addition, benign SFT has much better prognosis than malignant case.

Objective To investigate the clinical characteristics and risk factors of plastic bronchitis(PB)occurrence in children patients with refractory Mycoplasma pneumoniae pneumonia(RMPP).Methods A retrospective analysis was performed on the clinical data of 399 children patients with RMPP treated by fiberoptic bronchoscopy hospitalized in this hospital from January 2017 to December 2019.The pa-tients were divided into the PB group(n=142)and non-PB group(n=257)according to whether or not find-ing PB under fiberoptic bronchoscopy.The differences in clinical characteristics,laboratory detection indicators and imageological manifestations were compared between the two groups.The risk factors of PB occurrence in children RMPP were analyzed.Results Compared with the non-PB group,the incidence rates of hypoxemia and extrapul-monary complications,and the highest body temperature in the PB group were higher,number of fever days and hospitalization days was longer,the proportions of hormone and intravenous injection of immunoglobulin were higher,the levels of NEUT,CRP,IL-6,AST,ALT LDH CK and D-Dimer and incidence rates of pulmo-nary atelectasis and pleural effusion were higher,the levels of PLT and lymphocytes were lower,and the differences were statistically significant(P＜0.05).The receiver operating characteristic(ROC)curve analy-sis results showed that the highest body temperature,NEUT,PCT,IL-6,AST and LDH could serve as the predictive indicators for PB occurrence in RMPP(P＜0.05).The multivariate logistic regression analysis re-sults showed that the highest body temperature＞39.8 ℃,NEUT＞72.9％,IL-6＞26.65 pg/mL,AST＞49.5 U/L and pulmonary atelectasis were the risk factors of PB occurrence in RMPP.Conclusion Should pay at-tention to the risk factors of PB occurrence in children patients with RMPP and take necessary preventive measures to improve their prognosis.

It is found that acupuncture can significantly improve the clinical symptoms of rheumatoid arthritis (RA) such as pain and joint stiffness, and improve rheumatoid factor, high-sensitivity CRP, ESR and other clinical indicators. It can inhibit the proliferation of synovial cells, the apoptosis of chondrocytes, and regulate polarization balabce of mononuclear macrophages, T cells, as well as inhibit the inflammatory function of multiple immune cells, in order to improve inflammation state of RA joints. In clinical treatment of RA, bladder meridian, stomach meridian, spleen meridian , and Governor Vessel are mostly selected. Acupoints with the efficacy of warming meridian, dispelling coldness and dredging collaterals were commonly selected such as Zusanli (ST36), Yanglinquan (GB34), Dazhui (GV14), Quchi (LI11). Several researches have proved that combined therapy of acupuncture and medicine is worthy promotion in clinic.

Objective:To evaluate the efficacy and safety of the gemcitabine combined with oxaliplatin (GEMOX) regimen in the postoperative adjuvant treatment for the patients with cisplatin-intolerant uroepithelial cancer.Methods:The clinical data of 98 patients with uroepithelial carcinoma intolerant to cisplatin chemotherapy who underwent radical surgery from August 2017 to October 2022 at Drum Tower Hospital of Nanjing University School of Medicine were retrospectively analysed. The patients were divided into the adjuvant chemotherapy group and the observation group according to whether or not they underwent adjuvant chemotherapy after surgery. The adjuvant chemotherapy group received postoperative chemotherapy with the GEMOX regimen (gemcitabine 1 000 mg/m 2 intravenously on days 1 and 8, oxaliplatin 130 mg/m 2 intravenously on day 2, every 3 weeks as a cycle), and the observation group did not undergo postoperative adjuvant chemotherapy. In the adjuvant chemotherapy group, there were 33 males and 10 females, the patients’ age was (67.8±7.3) years old, 33 cases with estimated glomerular filtration rate (eGFR) ≤60 ml/(min·1.73m 2), and 10 cases with a Eastern Cooperative Oncology Group (ECOG) functional status score of >1. The postoperative pathology showed 39 cases were in stage T 3, 4 cases in stage T 4, and lymph node positivity (N+ ) was found in 10 cases. There were 55 cases in the observation group, with 42 males and 13 females and the age of (70.7±7.7) years old. Forty-two of them had an eGFR ≤60 ml/(min·1.73m 2), and 13 of them had a ECOG score of >1. The postoperative pathology showed 48 cases were in stage T 3, 7 cases in stage T 4, and 13 cases of N+. The changes in renal function, ECOG scores, and adverse reactions were observed in adjuvant chemotherapy group. Kaplan-Meier method was used to estimate the survival rate, and the log-rank test was used to compare the survival rate between groups. Multifactorial Cox regression was used to analyse the correlation between age, lymph nodes, whether or not to combine with adjuvant chemotherapy and the survival of patients. Results:All patients in this study were followed up for 3 to 75 months, with a median follow-up time of 22 (14, 34) months. The recurrence rates were 83.6%(46/55) and 65.1%(28/43) in the observation and adjuvant chemotherapy groups, respectively, and the disease mortality rates were 52.7%(29/55) and 27.9%(12/43), respectively. The results of the Kaplan-Meier survival analyses showed that the 1-, 2- and 3-year disease-free survival rates in the adjuvant chemotherapy group were 62.8%, 48.6% and 41.1%, respectively, and the 1-, 2- and 3-year overall survival rates were 86.0%, 79.0% and 76.4%, respectively. The 1-, 2- and 3-year disease-free survival rates of the observation group were 58.2%, 22.6% and 9.6%, respectively, and the 1-, 2- and 3-year overall survival rates were 78.2%, 49.4% and 42.8%, respectively. The adjuvant chemotherapy group had an advantage over the observation group regarding disease-free and overall survival rates (all P<0.05). The results of multifactorial Cox regression analysis suggested that the functional status score and the presence or absence of positive lymph nodes, diabetes mellitus, and co-adjuvant chemotherapy were independent risk factors affecting the survival of the patients ( P<0.05). Forty-three cases had 1 to 6 courses of adjuvant chemotherapy, with a median course of 4 (2, 4). In terms of safety, the most common adverse reaction in the gastrointestinal tract was loss of appetite (53.4%, 23/43), the most common grade 1 to 2 adverse reaction in myelosuppression was a decrease in haemoglobin (51.2%, 22/43), and the most common grade 3 to 4 adverse reaction was thrombocytopenia (9.3%, 4/43). The eGFR of 33 patients with renal insufficiency in the adjuvant chemotherapy group was higher after each administration cycle than before ( P<0.05), and renal function did not deteriorate with the increase in administration cycles. Ten patients with a ECOG score of 2 remained with a score of 2 after chemotherapy. Conclusions:In patients with cisplatin-intolerant uroepithelial cancer, gemcitabine in combination with an oxaliplatin regimen improves the overall survival of patients. At the same time, it is well tolerated without increasing nephrotoxicity, making it an optional postoperative adjuvant treatment for patients with cisplatin-intolerant uroepithelial cancer.

The construction of experimental animal models plays an important supporting role in research into the mechanisms of action of Chinese medicines.There have been increasing reports of the construction and evaluation of animal models of spleen deficiency;however,the construction method have involved different standards and there has been insufficient objectification of the evaluation indexes.In this review,we summarize the construction and evaluation method of animal models of spleen deficiency from the aspects of animal selection,model establishment,macroscopic characterization,behavioral experiments,and objective indexes of spleen deficiency,with a view to providing theoretical guidance for the construction of experimental animal models of spleen deficiency and references for the selection of animal model platforms for spleen deficiency.

Objective To evaluate the effectiveness of a 1470 nm semiconductor laser therapeutic instrument(referred to as a curestar therapeutic instrument)for prostatectomy in Beagle dogs.Methods Twenty-eight adult male Beagle dogs were randomly divided into three groups:sham(n=3),experimental(n=15),and control(n=10).The experimental group was further divided into three subgroups:120 W/50 W,150 W/50 W,and 160 W/50 W for vaporization cutting/coagulation hemostasis.The control group was divided into two subgroups:120 W/50 W and 150 W/50 W with five in each subgroup.Experimental and control groups underwent canine prostatectomy through the entrance of the bladder neck under electrocision.The operational suitability and effectiveness of the product during surgery were assessed.After the operation,the general condition of the dogs was observed,and blood biochemical and hematological indicators were measured before,immediately after,and at 3,7,and 28 days after the operation.At 1 h and 4 weeks after surgery,B-ultrasound and electric resection were performed under anesthesia to observe the conditions of the urethra and prostate,and prostatic tissue was subjected to HE staining for pathological observations.The thickness of the coagulation layer at 1 h after the operation and repair of the urothelial epithelium at 4 weeks were analyzed.Results During the operation,experimental and control groups had good operability and showed good vaporization cutting and coagulation hemostasis performance.After the operation,no significant effects were observed on the general condition,and blood biochemical and hematological indicators of the dogs.Ultrasound showed that the urethral expansion was visible immediately after the operation,and the echo of the urethral epithelium was slightly enhanced.At 4 weeks,the prostate tissue had a slightly low echo with uniformly distributed small point-like echoes inside,and the capsule had a linearly high echo,consistent with the sham group.The weight of the vaporized prostate tissue in experimental and control groups was 0.91～1.33 g with a resection rate of 17.11％～20.27％.As the power of vaporization cutting increased,the laser emission time gradually decreased,while the vaporization cutting speed and efficiency both increased.However,no significant difference was found between experimental and control groups(P＞0.05).Under the electrocision microscope,a burn-like change was observed in the surgical wounds of the prostate urethra in experimental and control groups at 1 h after surgery,and the boundary between the wound and normal urothelium was visible.At 4 weeks,the urothelium of the prostate had been repaired and flattened,and the boundary with the surrounding normal urothelium was blurred.Similarly,pathological observations showed that experimental and control groups had significant damage to the prostate urethral orifice at 1 h after surgery with a small amount of carbonization and coagulative necrosis on the surface of the wound,a small amount of inflammatory cell infiltration,and a coagulation layer thickness of approximately 0.4 mm.At 4 weeks,the prostate urethral morphology of the sham group was normal,whereas experimental and control groups showed new epithelial growth covering the wound with a uniform thickness and no coagulative necrosis tissue attached to the wound.A mild inflammatory reaction was still present in the surrounding area,fibroblast proliferation was obvious,and stromal and epithelial cell proliferation was visible in the surrounding prostate,some of which showed squamous metaplasia.The prostate capsule was intact and the morphology of the surrounding nerves and blood vessels was normal.Conclusions The curestar therapy instrument is effective for prostatectomy in Beagle dogs with good vaporization cutting and coagulation hemostasis performance.No significant difference was found in postoperative physiological indicators compared with the sham group.
