Objective: To investigate the association between plant-based dietary patterns and gestational weight gain (GWG) among pregnant women with gestational diabetes mellitus (GDM), so as to provide the evidence for guiding the reasonable diet during pregnancy. Methods: GDM pregnant women who participated in the WeBirth project in Hangzhou Obstetrics and Gynecology Hospital were selected. Maternal age and pre-pregnancy body mass index (BMI) were collected. The Chinese version of Pregnancy Physical Activity questionnaire was used to assess the daily activity equivalent. The food frequency questionnaire was used to collect the frequency and amount of food intake in the last month before enrollment. The overall plant-based diet index (PDI), healthy plant-based diet index (HPDI), and unhealthy plant-based diet index (UPDI) were constructed based on food intake and grouped by quartiles. Multiple linear regression models were used to analyze the association between plant-based dietary patterns and GWG. Results: A total of 1 943 pregnant women with GDM, with a median age of 30.91 (interquartile range, 4.92) years. The median BMI of pre-pregnancy was 21.51 (interquartile range, 4.06) kg/m2. The medians of PDI, HPDI and UPDI were 32.42 (interquartile range, 4.60), 32.48 (interquartile range, 4.41) and 32.40 (interquartile range, 5.36), respectively. The median of GWG was 11.30 (interquartile range, 4.52) kg. Multiple linear regression analysis showed that PDI (Q3 group, β=0.674, 95%CI: 0.064-1.285; Q4 group, β=0.702, 95%CI: 0.098-1.306), UPDI (Q3 group, β=1.332, 95%CI: 0.771-1.894; Q4 group, β=1.115, 95%CI: 0.550-1.681) were positively associated with GWG after adjusting for age, pre-pregnancy BMI, daily activity equivalent and daily energy intake. No significant association was found between HPDI and GWG (all P>0.05). Conclusion UPDI was associated with a higher risk of GWG in pregnant women with GDM.

Osteoarthritis (OA) causes chronic pain that significantly impairs quality of life, with current treatments often proving insufficient and accompanied by adverse effects. Recent research has identified the dorsal root ganglion (DRG) and its resident macrophages as crucial mediators of chronic OA pain through neuroinflammation driven by macrophage polarization. We present a novel injectable thermo-sensitive hydrogel system, KAF@PLEL, designed to deliver an anti-inflammatory peptide (KAF) specifically to the DRG. This biodegradable hydrogel enables sustained KAF release, promoting the reprogramming of DRG macrophages from pro-inflammatory to anti-inflammatory phenotypes. Through comprehensive in vitro and in vivo studies, we evaluated the hydrogel's biocompatibility, effects on macrophage polarization, and therapeutic efficacy in chronic OA pain management. The system demonstrated significant capabilities in preserving macrophage mitochondrial function, suppressing neuroinflammation, alleviating chronic OA pain, reducing cartilage degradation, and improving motor function in OA rat models. The sustained-release properties of KAF@PLEL enabled prolonged therapeutic effects while minimizing systemic exposure and side effects. These findings suggest that KAF@PLEL represents a promising therapeutic approach for improving outcomes in OA patients through targeted, sustained treatment.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

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.

Objectives:To explore the factors that may be associated with the occurrence of major adverse cardiac events(MACEs)after posterior lumbar spinal fusion in patients with degenerative lumbar spinal disor-ders.Methods:The clinical data of 96 patients who underwent lumbar spinal fusion for degenerative lumbar spinal disorders at Beijing Anzhen Hospital from January 2018 to July 2023 were retrospectively analyzed,53 males and 44 females were included with the average age of 64.1±10.1 years.The patients were grouped ac-cording to whether MACEs(cardiac arrest,new or worsening arrhythmia,acute myocardial infarction,or angina pectoris and heart failure)occurred within 1 year after lumbar spine fusion surgery.The general conditions[American Society of Anesthesiologists(ASA)classification,Charlson comorbidity index(CCI),revised cardiac risk index(RCRI),etc.],preoperative examinations(hematocrit,serum albumin,left ventricular ejection fraction,etc.),surgical parameters(Mirza invasiveness of the surgery index,operative time,estimated blood loss,etc.),and intraoperative monitoring indexes(baseline mean artery pressure,urine output,autonomous blood transfusion,etc.)were compared between the two groups.Results:The CCI index,RCRI index,echocardiograph E-wave maximal flow rate,estimated intraoperative blood loss,baseline mean arterial pressure,and intraoperative au-tologous blood transfusion in the group without MACEs were significantly lower than those in the group with(0.9±1.0 vs 1.6±1.5;1.5±0.7 vs 2.0±0.8;70.3±18.2 vs 82.6±36.9;705±560.6 vs 1193±1332.9;103.6±15.9 vs 112.1±12.1;399.5±368.3 vs 637.6±470.5),with statistically significant differenccs(P＜0.05).Multifactorial logistic regression analysis suggested that both the CCI index and estimated intraoperative blood loss were correlated with the MACEs statistically(OR=1.968,P=0.007;OR=1.001,P=0.023).Conclusions:The CCI and operative blood loss may be associated with the MACEs after posterior lumbar spinal fusion in patients with degenera-tive lumbar spinal disorders.

The incidence and detection rates of benign and low-grade malignant pancreatic tumors have risen yearly.For patients with such tumors,traditional radical resection procedures often result in excessive loss of normal pancreatic parenchyma,leading to complications such as postoperative insufficiency of both exocrine and endocrine functions.Studies have shown that functional-preserving surgeries,such as minimally invasive enucleation or partial resection surgeries,can maximize the protection of patients'pancreatic function and improve long-term quality of life.However,for some tumors deep within the pancreatic parenchyma,accurately locating the tumor and protecting the pancreatic duct pose challenges.Intraoperative ultrasound(IOUS)has become an ideal intraoperative imaging tool,often referred to as the surgeon's"third eye"because of its portability,ability to provide real-time high-resolution information,non-reliance on ionizing radiation,and the fact that it does not require special patient preparation.With advancements in technology,the application scope of IOUS has expanded beyond its initially limited diagnostic role to various surgical applications,including identifying non-palpable lesions,guiding surgical strategies,and staging tumors.In the current era of minimally invasive and precision surgery,the proficiency of surgeons in using IOUS has become an important issue.This article reviews the history of IOUS applications,summarizes the advantages and basic usage methods of robotic IOUS,and shares techniques for applying IOUS in robot-assisted precise resection of pancreatic tumors.

Abstract: Objective　To analyze the risk factors for HIV/AIDS mortality after receiving antiviral treatment in Tongchuan City, and to provide a scientific basis for implementing precision treatment in Tongchuan City. Methods　A retrospective cohort study was conducted to collect general demographic characteristics and survival-related information of HIV/AIDS individuals who received antiviral treatment in Tongchuan City from 2005 to 2023. Mortality table analysis was used to assess the cumulative survival rate, Cox regression model was used to analyze survival influencing factors, and a nomogram was constructed to predict the prognosis of antiviral treatment. Results A total of 410 HIV/AIDS patients underwent antiviral treatment, with the shortest observation period being 0 months and the longest 222 months, and the median survival time was 71 months (QR: 64-106); among the 362 cases followed up, there were 39 AIDS-related deaths. The cumulative survival rates after 1, 5, and 10 years of antiretroviral therapy were 96.2%, 91.3%, and 83.0%, respectively. Multivariate Cox analysis showed that patients with a higher level of education (college degree or above) (HR=0.349, 95%CI: 0.159-0.769) and without clinical symptoms (HR=0.357, 95%CI: 0.178-0.715) had a lower risk of death after antiretroviral treatment, whereas patients with a CD4 cell count <200 cells/μL group (HR=9.383, 95% CI: 2.879-30.578) had a higher risk of death. Based on the above three influencing factors, a nomogram model was constructed. Internal validation showed that the model's discriminative ability with a C-index of 0.859 (95% CI: 0.762-0.956), and the calibration curve indicated good consistency, demonstrating the model's good predictive ability. Conclusions　Tongchuan City should expand health education on AIDS prevention and control, strengthen HIV monitoring, carry out education on compliance with antiviral treatment among HIV/AIDS individuals, conduct timely CD4 cell count detection, and use the constructed nomogram model to assist in precise diagnosis and treatment in clinical practice.

Monoclonal gammopathy of undetermined significance combined with renal damage is named monoclonal gammopathy of renal significance.There are few reports about IgA vasculitis in patients with monoclonal gammopathy of undetermined significance.Here,we report a case of monoclonal gammopathy of renal significance,who had manifestations of IgA vasculitis,including purpura,gastrointestinal bleeding and joint pain.The patient had elevated serum creatinine levels,prompting further investigation through immunofixation electrophoresis and bone marrow aspiration biopsy.Immunofixation electrophoresis showed IgA-λ-type monoclonal immunoglobulin,while the bone marrow aspiration biopsy suggested plas-macytosis.Kidney biopsy indicated membranous hyperplastic glomerulonephritis,light and heavy chain deposition,IgA-λ.The patient was diagnosed with monoclonal gammopathy of renal significance.In light of the elevated serum creatinine,the patient was treated with chemotherapy regimen(bortezomib+cy-clophosphamide+dexamethasone).After chemotherapy,there was no significant improvement in the patient's renal function.Subsequently,the patient experienced abdominal pain,skin purpura,joint pain and severe gastrointestinal bleeding.Gastroenteroscopy did not find the exact bleeding position.Angiography revealed hyperplasia of left jejunal artery.Surgical operation found that the bleeding site was located between the jejunum and ileum,where scattered hemorrhagic spots and multiple ulcers were present on the surface of the small intestine,with the deepest ulcers reaching the serosal layer.And the damaged intestine was removed during the operation.Intestinal pathology showed multiple intestinal submu-cosal arteritis,rusulting in intestinal wall necrosis and multiple ulcers.Considering intestinal lesions as gastrointestinal involvement of IgA vasculitis,methylprednisolone was used continually after the opera-tion,and the patient's condition was improved.However,after half a year,the patient suffered a severe respiratory infection and experienced a recurrence of serious gastrointestinal bleeding.It was considered that the infection triggered the activity of IgA vasculitis,accompanied by gastrointestinal involvement.Fi-nally,the patient died from gastrointestinal bleeding.The present case represented a patient with mono-clonal gammopathy of renal significance and IgA vasculitis,prominently presenting with renal insufficien-cy and severe gastrointestinal bleeding,making the diagnosis and treatment process complex.Patients with IgA monoclonal gammopathy who presented with abdominal pain,purpura,and arthralgia should be vigilant for the possibility of concomitant IgA vasculitis.The treatment of cases with IgA vasculitis com-bined with monoclonal gammopathy of renal significance was rather challenging.Plasma cell targeting therapy might be an effective regimen for IgA vasculitis with monoclonal gammopathy.However,patients with poor renal response to the treatment indicated poor prognosis.

Objective : To examine the association between dietary patterns during pregnancy and gestational diabetes mellitus (GDM), so as to provide the evidence for guiding the establishment of healthy and balanced dietary patterns and reducing the prevalence of GDM. Methods: Pregnant women who underwent oral glucose tolerance tests in Hangzhou Obstetrics and Gynecological Hospital from 2020 to 2021 were enrolled, and their demographic information were collected using questionnaires. Pregnant women's diets during the past three months were collected using Food Frequency Questionnaires (FFQs), and dietary patterns were extracted using principal component analysis. In addition, the association between dietary patterns and risk of GDM was examined using a multivariable logistic regression model. Results: A total of 1 689 pregnant women were included, with a median age of 28.53 (interquartile range, 2.47) years and a median gestational age of 26.00 (interquartile range, 2.00) weeks. Five dietary patterns were identified according to pregnant women's types of diets, including meat-based diets, dessert-fruit-refined grain diets, plant-based diets, eggs-milk-nut diets and whole-grain diets, with a cumulative contribution rate of 58.76%. The prevalence of GDM was 24.57% (415 cases) among the study subjects. Multivariable logistic regression analysis showed that pregnant women with scores in the highest quartile (Q4) of the meat-based diets had an increased risk of GDM (OR=1.372, 95%CI: 1.043-2.055) relative to those with scores in the lowest quartile (Q1), and pregnant women with Q4 scores of the dessert-fruit-refined grain diets had an increased risk of GDM (OR=1.743, 95%CI: 1.397-2.432) relative to those with Q1 scores, while pregnant women with Q4 scores of the plant-based diets had a reduced risk of GDM (OR=0.382, 95%CI: 0.346-0.613) relative to those with Q1 scores. Conclusion A plant-based dietary pattern may reduce the risk of GDM, while meat-based and dessert-fruit-refined grain dietary patterns may increase the risk of GDM.
