Objective:To explore the assessment value of ultrasound scoring system combined with shear wave elastography(SWE)on curative effect of IgG4-related submandibular and lacrimal gland inflammation.Methods:This study was a prospective cohort study.A total of 103 patients with IgG4-related submandibular and/or lacrimal gland inflammation who admitted to the Department of Rheumatology and Immunology of Beijing Friendship Hospital,Capital Medical University from September 2022 to December 2024 were consecutively included.They were divided into an effective group(45 cases)and a non-effective group(58 cases)based on the curative effect.All patients were assessed by conventional ultrasound and SWE before and after treatment.Logistic regression analysis was used to determine the independent influencing factors of assessing the curative effect,and then,a receiver operating characteristic(ROC)curve and nomograms were drawn.Results:There were no statistically significant differences in gender and age between the effective group and the non-effective group(P>0.05).The difference between the submandibular and lacrimal gland score,change rate of score,difference of mean Young's modulus(Emean),Emean change rate,difference of maximum value of Young's modulus(Emax),and Emax change rate in the effective group were all higher than those in the non-effective group,and the differences were statistically significant(Z=-7.916,-7.680,-6.767,-6.722,-6.360,-5.957,P<0.05),respectively.The difference between the submandibular and lacrimal gland score(OR=2.90,P<0.001)and the Emax difference(OR=1.18,P<0.05)had diagnostic value for assessing the curative effectiveness.The area under curve(AUC)value,sensitivity,specificity and accuracy of the difference between submandibular and lacrimal gland score were respectively 0.945,88.9%,94.8%and 87.4%in assessing the curative effectiveness.The above indicators of Emax difference were respectively 0.866,86.7%,70.7%and 77.7%in assessing the curative effectiveness.The above indicators of the combination of them were respectively 0.976,93.3%,94.8%and 94.2%.Conclusion:The combination of the conventional ultrasound scoring system and SWE has higher diagnostic value in assessing the curative effect of IgG4-related submandibular and lacrimal gland inflammation.The combined application can significantly improve the accuracy and provide reliable imaging reference for clinical practice.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Osteochondral lesion of talus (OLT) is a foot and ankle disease characterized by ankle pain, which may impact the joint function and life quality. If managed improperly, it may lead to a further ankle arthritis, severely compromising the prognosis. The therapeutic effect of conservative treatment for OLT is still uncertain. Surgery is still the main treatment modality for OLT with various techniques. However, the optimized surgical technique is still inconclusive, furthermore, regeneration and repair of cartilage after debridement is also a great challenge for the treatment of OLT. Platelet-rich plasma (PRP) with good repair effect on cartilage injury is gradually applied in the treatment of OLT. However, there still lacks the unified understanding of the technique and specification of PRP for the treatment of OLT. Therefore, National Orthopedics Center of Shanghai Sixth People′s Hospital allied Foot Ankle Basic Research & Orthopedics Group, Chinese Association of Orthopedic Surgeons; Foot and Ankle Committee of Chinese Association of Sports Medicine Physicians; and Foot and Ankle Group of Orthopedic Specialized Branch of Shanghai Medical Association to organize related experts to formulate the Expert consensus on platelet- rich plasma treatment for osteochondral lesion of talus ( version2023). Fifteen recommendations were put forward upon PRP preparation, indications, contraindications and treatment methods of PRP for OLT, so as to standardize the PRP treatment for OLT.

Objective: To investigate the prevalence of hypertension among primary and middle school students living in Suzhou City, Jiangsu Province, so as to provide insights into comprehensive hypertension control among children and adolescents. Methods: Primary and middle school students at ages of 7 to 17 years were recruited for a questionnaire survey in Suzhou City using the stratified cluster random sampling method from September to December, 2020, and the height and body weight were measured. Blood pressure was measured at three separate clinic visits according to the national criteria Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years ( WS/T 610-2018 ), and the detection of elevated blood pressure was estimated at three separate visits. In addition, factors affecting elevated blood pressure were identified. Results: A total of 3 713 students were enrolled, including 1 924 boys ( 51.82% ) and 1 789 girls ( 48.18% ). The detection of elevated blood pressure was 13.63%, 5.36%, and 3.37% at three separate visits, respectively, and the prevalence of hypertension ( elevated blood pressure at all three visits ) was 3.37%. The detection rates of elevated blood pressure were all higher at three visits ( 16.90%, 8.40%, and 5.26% ) among students at ages of 12 to 17 years than among students at ages of 7 to 11 years ( 9.65%, 1.67%, and 1.07%, P<0.05 ). The detection of elevated blood pressure was significantly higher in boys ( 15.23% ) than in girls (11.91%) at the first visit ( P<0.05 ), while no significant differences were seen at the second or third visit ( P>0.05 ). In addition, higher detection rates of elevated blood pressure were seen in obese ( 27.62%, 11.51%, and 7.06% ) and overweight students ( 17.45%, 6.95%, and 4.85% ) than in students with normal weight ( 9.44%, 3.54%, and 2.15% ) at all three visits, and greater detection rates of elevated blood pressure were found in obese students than in overweight students at the first and second visits ( P<0.017 ). Conclusions The prevalence of hypertension was 3.37% based on three separate visits among primary and middle school students in Suzhou City. Measurement of blood pressure at three separate visits within different days is effective to reduce the false positive rate of hypertension and decrease misdiagnosis among children and adolescents.

: To assess the relationship between high blood pressure (HBP) and body mass index (BMI), waist circumference (WC), and waist-height ratio (WHtR) among children and adolescents in Suzhou. Methods: A total of 3 150 children and adolescents aged 7-17 years were enrolled through stratified cluster sampling from September to October, 2019. Questionnaire survey was conducted, and height, weight, WC and BP were measured to calculate BMI and WHtR, relationship of HBP and adiposity indicators were evaluated. Results: The prevalence of HBP was 11.3%, overweight/obesity rate was 28.5%, and centrality obesity based on WC and WHtR was 20.6% and 23.7%, respectively. There were significant relationships between HBP and BMI, WC, and WHtR (χ2=157.80,105.87,124.17,P<0.01). As Logistic regression showed, compared to normal weight group, overweight/obesity based on BMI had positive relation with HBP (OR=3.89, 95%CI=3.09-4.90); compared to normal WC/WHtR, centrality obesity showed positive association with HBP (WC: OR=3.05, 95%CI=2.41-3.86; WHtR: OR=3.35, 95%CI=2.67-4.21). Meanwhile, BMI had joint effects on HBP with WC/WHtR. Specifically subjects with overweight/obesity and center obesity had higher risk of HBP, compared to normal BMI and WC subjects(OR=4.28, 95%CI=3.31-5.53). Conclusion Significant relationships between HBP and BMI, WC, and WHtR were found. BMI had joint effects on HBP with WC/WHtR. Keeping normal body weight and WC/ WHtR would have significant effects on HBP.

Objective: To explore the key points of nursing in the process of diagnosing and treating the common complication--- post-transplantation lymphoproliferative disorder (PTLD) after pediatric liver transplantation. Methods: The clinical data of 21 children with PTLD after liver transplantation. The key point of nursing in the process of prevention, onset, diagnosis and treatment was summarized. Results: With the individual and combined treatments 18 patients gained remission except for 1 patient died because of perforation and sequent intractable haemorrhage and 2 patient died for the development of lymphoma. In terms of nursing, during the prevention stage, it is critical to insist the regular follow-up to make early diagnosis. More efforts should be made to obtain the children′s cooperation to complete the examination. During the infusion of rituximab, strengthened monitoring is necessary and more attention should be paid to the special nursing when other complications such as intractable haemorrhage, intestinal obstruction or perforation occurs. Conclusions The nursing care of PTLD is complicated. Individual and careful nursing regimens should be made based on the specific situations in different stages.
