Objective:To explore the clinical characteristics, diagnosis and treatment strategies, and prognosis of pulmonary embolism (PE) complicating childhood rheumatic diseases.Methods:A retrospective case series study was performed on the demographic data, laboratory indicators, imaging features, treatment regimens, and follow-up data of 8 children with rheumatic diseases complicated by PE who were admitted to the Department of Rheumatology and Immunology, Capital Center for Children′s Health, Capital Medical University from January 2014 to October 2023.Results:Among the 8 children, there were 4 boys and 4 girls, with an age of 12.0 (7.5, 13.0) years. Among the primary diseases, there were 3 cases of systemic lupus erythematosus, 2 cases of Beh?et′s disease, 2 cases of Takayasu arteritis, and 1 case of antiphospholipid syndrome. All children developed PE during the active phase of the primary disease. PE was detected at the onset of the primary disease in 3 cases, and the median time from the diagnosis of the primary disease to the development of PE was 10.0 (6.0, 25.0) months in the remaining 5 cases. Fever was present in all 8 children, 4 cases were accompanied by chest tightness, dyspnea, etc., and 2 cases only presented with fever. Laboratory examinations revealed the following results: erythrocyte sedimentation rate was 42.0 (17.0, 78.0) mm/1 h, high-sensitivity C-reactive protein was 12.7 (2.6, 78.7) mg/L, white blood cell count was 9.6 (7.2, 18.7)×10 9/L; D-dimer was 2.3 (0.9, 6.2) mg/L; and hemoglobin was (109±16) g/L.Imaging examinations revealed that 5 cases had involvement of the bilateral lower pulmonary arteries, 5 cases had peripheral embolism, and 3 cases had central PE. Complications included 3 cases of deep vein thrombosis, 2 cases of intracranial venous sinus thrombosis, and 1 case of mild pulmonary hypertension.In terms of treatment, 7 cases received anticoagulation with heparin followed by warfarin. Immunomodulation was mainly based on glucocorticoids combined with immunosuppressants, and 4 cases were combined with biological agents. The follow-up time of 4.17 (1.75, 7.17) years, the time for complete absorption of PE was 10.5 (6.0, 18.0) months; all 8 children had no target events, with no recurrence or chronic thromboembolic pulmonary hypertension, and the pulmonary artery remodeling was good. Conclusions:PE complicating childhood rheumatic diseases is closely related to the activity of the primary disease. The clinical manifestations are insidious, with fever as the main symptom. Imaging examination is the key to diagnosis.Early adoption of heparin followed by warfarin anticoagulation and glucocorticoids combined with immunosuppressants and (or) biological agents to control the primary disease can achieve a favorable prognosis.

Based on the concept of "blood exhaustion" from The Inner Canon of Yellow Emperor （《黄帝内经》）， a three-stage syndrome differentiation and treatment strategy for cancer-related anorexia-cachexia syndrome is proposeed. In the cancer-induced anorexia stage， the pathogenesis is characterized by cancer consuming the spleen and stomach， leading to stagnation of transportation and transformation in the middle jiao （焦）. Treatment should focus on strengthening the spleen， promoting appetite， dispersing accumulation， and aiding digestion， with modified Zisheng Pills （资生丸） in Extensive Notes on Medicine from Xian Xing Studio （《先醒斋医学广笔记》） or Zisheng Decoction （资生汤） in Records of Chinese Medicine with Reference to Western Medicine （《医学衷中参西录》）. In the pre-cachectic stage of malnutrition， the pathogenesis involves insufficient nourishment of blood and qi with essence depletion hindering production. Treatment should focus on nourishing blood and harmonizing ying （营）， warming yang and supplementing qi， and modified Huangqi Jianzhong Decoction （黄芪建中汤） can be used. In the cachectic stage， the pathogenesis involves blood deficiency and essence exhaustion， with blood stasis obstructing the collaterals. The therapeutic approach should focus on tonifying deficiency and replenishing essence， unblocking collaterals， and removing stasis， and modified Buzhong Yiqi Decoction （补中益气汤） and Zuo Gui Beverage （左归饮） are suggested.

Objective To systematically evaluate the efficacy and safety of proximal gastrectomy (PG) versus total gastrectomy (TG) for the treatment of Siewert type Ⅱ/Ⅲ adenocarcinoma of the esophagogastric junction (AEG). Methods PubMed, The Cochrane Library, Web of Science, EMbase, CNKI, Wanfang, and VIP databases were searched for literature comparing the efficacy and safety of PG and TG for the treatment of Siewert type Ⅱ/Ⅲ AEG. The search period was from database inception to March 2023. Meta-analysis was performed using Review Manager 5.4 software. Results A total of 23 articles were included, including 16 retrospective cohort studies, 5 prospective cohort studies, and 2 randomized controlled trials. The total sample size was 2 826 patients, with 1 389 patients undergoing PG and 1 437 patients undergoing TG. Meta-analysis results showed that compared with TG, PG had less intraoperative blood loss [MD=−19.85, 95%CI (−37.20, −2.51), P=0.02] and shorter postoperative hospital stay [MD=−1.23, 95%CI (−2.38, −0.08), P=0.04]. TG had a greater number of lymph nodes dissected [MD=−6.20, 95%CI (−7.68, −4.71), P<0.001] and a lower incidence of reflux esophagitis [MD=3.02, 95%CI (1.24, 7.34), P=0.01]. There were no statistically significant differences between the two surgical approaches in terms of operative time, postoperative survival rate (1-year, 3-year, 5-year), and postoperative overall complications (P>0.05). Conclusion PG has advantages in terms of intraoperative blood loss and postoperative hospital stay, while TG has advantages in terms of the number of lymph nodes dissected and the incidence of reflux esophagitis. There is no significant difference in long-term survival between the two surgical approaches.

Objective:To investigate the value of carotid，radial and podalic artery intima thickness（CIT，RIT，PIT）combined with monocyte to high-density lipoprotein ratio（MHR）in predicting the severity of coronary artery stenosis in patients with premature coronary artery disease（PCAD）.Methods:A total of 80 patients with PCAD who received treatment in Henan Provincial People's Hospital from October 2023 to May 2024 were prospectively recruited，and they were divided into high group（≥41 score，40 cases）and low group（＜41 score，40 cases）according to the median dichotomy of Gensini score. Thirty-four gender，age and body mass index（BMI）-matched healthy volunteers were selected as the control group. The CIT，RIT，PIT，media and intima media thickness of carotid，radial artery and podalic artery（CMT，RMT，PMT，CIMT，RIMT，PIMT）were measured using 24 MHz ultra-high frequency ultrasound probe，and the ratio of intima to media thickness（CIT/CMT，RIT/RMT，PIT/PMT）was calculated. The differences of general clinical data，laboratory indexes and ultrasonic parameters among the three groups were compared. Risk factors affecting the severity of coronary stenosis in PCAD patients were explored by binary logistic regression. Subject working characteristic curves were plotted，area under the curve（AUC）was calculated，and the values of each ultrasound parameter and MHR in the independent and combined diagnosis of the severity of coronary artery stenosis in PCAD patients were evaluated.Results:①There were no statistically significant differences in age，gender，BMI，total cholesterol，CMT，RMT and PMT among the three groups（all P＞0.05）. There were no statistically significant differences in the comparison of smoking，hypertension，diabetes mellitus，systolic blood pressure，diastolic blood pressure，low-density lipoprotein cholesterol，total cholesterol，and triglycerides between the two subgroups of the PCAD（all P>0.05）. ②CIT，CIMT，CIT/CMT，RIT，RIMT，RIT/RMT，PIT，PIMT，PIT/PMT were thickened in the high group compared with the low group，and MHR was higher than in the low group（all P<0.05），the differences in the above parameters remained statistically significant when comparing the PCAD group with the control group（all P<0.05）. ③The AUC values for MHR，CIT，RIT and PIT alone to predict the severity of coronary stenosis in patients with PCAD were 0.781，0.767，0.780 and 0.722，respectively. The combined diagnostic efficiency of the four parameters was better than the independent diagnostic efficiency（AUC = 0.885）. Conclusions:CIT，RIT and PIT are thicker in PCAD patients with high Gensini score and the combination of artery intima thickness and MHR has good efficacy in predicting the severity of coronary artery stenosis in PCAD patients.

Objective:To assess the efficacy and safety profile of antaitasvir phosphate combined with yiqibuvir in the treatment of chronic hepatitis C (CHC) of various genotypes, without cirrhosis or with compensated cirrhosis.Methods:394 cases with CHC from 22 centers were collected from October 2021 to April 2023. They were randomly assigned to receive either the experimental drugs (antaitasvir phosphate 100 mg+yiqibuvir 600 mg) or placebo treatment in a 3∶1 ratio. The patients were administered drugs once a day for 12 consecutive weeks, and then followed up for 24 weeks after treatment cessation. All subjects were unblinded at the four-week follow-up following drug discontinuation, with the experimental drug group continuing to complete subsequent post-discontinuation follow-up. The placebo group was switched to receive the experimental drugs for a repeated 12-week treatment period and followed up for another 24 weeks after discontinuation of the drug (placebo delayed treatment phase).The sustained virologic response rate (SVR12) was observed for subjects in the double-blind phase and the placebo delayed-treatment phase at 12 weeks after treatment cessation.Virological resistance analysis was performed on subjects who failed treatment. The primary efficacy endpoint was SVR12. The number and percentage of subjects who achieved "HCV RNA

Objective:To investigate the clinical characteristics, imaging features, risk factors, and prognosis of childhood-onset Takayasu arteritis (TAK) with pulmonary artery involvement.Methods:A retrospective cohort study was conducted in 107 pediatric patients who were initially diagnosed with childhood-onset TAK at Department of Rheumatology and Immunology, Capital Center for Children′s Health, Capital Medical Universiy, from January 2010 to December 2024. Clinical data, including demographic information, imaging features, treatment regimens, and prognosis were collected. Patients were divided into with and without pulmonary artery involvement groups. Intergroup comparisons were performed. Multivariate logistic regression was used to identify risk factors for pulmonary artery involvement. Kaplan-Meier analysis with Log-Rank testing was used for survival analyze.Results:Among 107 children with TAK, 26 were male, 81 were female, with a diagnosis age of 88 (5, 137) months. Sixteen cases were in the pulmonary artery involvement group and 91 cases in the non-pulmonary artery involvement group. The pulmonary artery involvement group was predominantly female (14 cases), with a diagnosis age of 39 (4, 104) months. The pulmonary artery involvement group had higher incidence rates of fatigue,pulmonary hypertension, right heart failure,superior mesenteric artery involvement,as well as higher neutrophil counts, C-reactive protein (CRP) levels (all P<0.05). Hemoglobin was lower in the pulmonary artery involvement group ( P<0.05). Imaging findings revealed that all 16 children in the pulmonary artery involvement group showed signs of pulmonary arterial wall thickening. Other manifestations included dilation in 2 cases, stenosis in 2 cases, and occlusion in 1 case. Unilateral involvement (12 cases) was more common, and the right pulmonary artery (10 cases) was more frequently affected. Independent risk factors for pulmonary artery involvement in childhood-onset TAK patients included superior mesenteric artery involvement ( OR=5.58, 95% CI 1.41-22.10, P=0.014) and elevated CRP levels ( OR=1.02, 95% CI 1.00-1.03, P=0.027). During a follow-up of 3.9 (1.4,8.1) years, 2 patients with pulmonary artery involvement (all with pulmonary hypertension), among the survivors in the pulmonary artery involvement group, 2 cases still exhibited persistent pulmonary artery dilation, and one case had pulmonary artery occlusion; and 6 patients (6.6%) without pulmonary artery involvement died. Patients with pulmonary artery involvement had significantly lower survival rates compared to those without involvement ( P=0.024). Conclusions:Childhood-onset TAK with pulmonary artery involvement has an insidious clinical presentation, and can progress to pulmonary hypertension, pulmonary artery occlusion, and a significantly reduced survival rate. Patients with mesenteric artery involvement or elevated CRP have higher risks of pulmonary artery involvement, requiring close pulmonary vascular monitoring and early intervention to improve prognosis.

OBJECTIVE: To investigate the effectiveness of using 3 hollow compression screws combined with 1 screw off-axis fixation under the guidance of three-dimensional (3D) printed guide plate with mortise-tenon joint structure (mortise-tenon joint plate) for the treatment of Pauwels type Ⅲ femoral neck fractures. METHODS: A clinical data of 78 patients with Pauwels type Ⅲ femoral neck fractures, who were admitted between August 2022 and August 2023 and met the selection criteria, was retrospectively analyzed. The operations were assisted with mortise-tenon joint plates in 26 cases (mortise-tenon joint plate group) and traditional guide plates in 28 cases (traditional plate group), and without guide plates in 24 cases (control group). There was no significant difference in the baseline data of gender, age, body mass index, cause of injury, and fracture side between groups ( P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, incision length, incidence of postoperative deep vein thrombosis of lower extremity, pain visual analogue scale (VAS) score at 1 week after operation, and Harris score of hip joint at 3 months after operation were recorded and compared. X-ray re-examination was taken to check the quality of fracture reduction, fracture healing, and the shortening length of the femoral neck at 3 months after operation, and the incidences of internal fixation failure and osteonecrosis of the femoral head during operation. RESULTS: Compared with the control group, the operation time, intraoperative blood loss, and frequency of intraoperative fluoroscopy reduced in the two plate groups, and the quality of fracture reduction was better, but the incision was longer, and the differences were significant ( P<0.05). The operation time and intraoperative blood loss were significantly higher in the traditional plate group than in the mortise-tenon joint plate group ( P<0.05), the incision was significantly longer ( P<0.05); and the difference in fracture reduction quality and the frequency of intraoperative fluoroscopy was not significant between two plate groups ( P>0.05). There was 1 case of deep vein thrombosis of lower extremity in the traditional plate group and 1 case in the control group, while there was no thrombosis in the mortise-tenon joint plate group. There was no significant difference in the incidence between groups ( P>0.05). All patients were followed up 12-15 months (mean, 13 months). There was no significant difference in VAS score at 1 week and Harris score at 3 months between groups ( P>0.05). Compared with the control group, the fracture healing time and the length of femoral neck shortening at 3 months after operation were significantly shorter in the two plate groups ( P<0.05). There was no significant difference between the two plate groups ( P>0.05). There was no significant difference in the incidences of non-union fractures, osteonecrosis of the femoral head, or internal fixation failure between groups ( P>0.05). CONCLUSION For Pauwels type Ⅲ femoral neck fractures, the use of 3D printed guide plate assisted reduction and fixation can shorten the fracture healing time, reduce the incidence of postoperative complications, and be more conducive to the early functional exercise of the affected limb. Compared with the traditional guide plate, the mortise-tenon joint plate can reduce the intraoperative bleeding and shorten the operation time.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.
