ObjectiveTo investigate the role of DEAD-box helicase 3 X-linked (DDX3X) in immune-mediated liver injury (ILI), and to clarify its mechanism by regulating endoplasmic reticulum stress (ERS)-dependent apoptotic pathway and its association with the clinical progression of hepatitis B. MethodsMice were given injection of concanavalin A (ConA) via the caudal vein to establish a model of ILI, PBS (control group) and different concentrations of ConA were injected into the tail vein of hepatocyte-specific DDX3X-knockout mice (DDX3XΔHep and DDX3X-flox mice (DDX3Xfl/fl), respectively.. The log-rank survival analysis, measurement of the serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and HE staining of liver tissue were performed to assess liver injury, and qRT-PCR and Western Blot were used to measure the mRNA and protein expression levels of glucose-regulated protein 78 (GRP78), CCAAT/enhancer-binding protein homologous protein (CHOP), and DDX3X in liver tissue. Intraperitoneal injection of 4-phenylbutyric acid (4-PBA, 100 mg/kg) was performed to inhibit ERS. Serum samples (n=30) and liver tissue samples (n=6) were collected from healthy controls, chronic hepatitis B (CHB) patients, and hepatitis B virus-associated liver failure (HBV-LF) patients; ELISA was used to measure the serum level of DDX3X, and qRT-PCR/Western Blot was used to analyze the expression of targets in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the control group of mice, the expression of DDX3X in the liver of mice induced by ConA was significantly increased after liver injury (P<0.05), and hepatocyte-specific DDX3X knockout increased the 72-hour survival rate of mice by 55% (compared with 20% in the DDX3Xfl/fl group), with significant reductions in the serum levels of ALT and AST (P<0.000 1) and the expression levels of the ERS markers GRP78 and CHOP (P<0.05). After ERS was inhibited by 4-PBA, there was alleviation of liver injury (with reductions in ALT and AST, P <0.001) and a reduction in DDX3X expression (P<0.01). The analysis of clinical samples showed that the mRNA and protein expression levels of liver DDX3X in CHB patients and HBV-LF patients were significantly higher than those in healthy controls (all P<0.01), and there was a significant increase in the serum level of DDX3X in HBV-LF patients (P<0.000 1). ConclusionDDX3X exacerbates ILI by regulating the ERS-dependent apoptotic pathway (GRP78/CHOP), and its expression is associated with the progression of hepatitis B. Therefore, it can be used as a potential therapeutic target.

ObjectiveMagnetoencephalography (MEG), a non-invasive neuroimaging technique, meticulously captures the magnetic fields emanating from brain electrical activity. Compared with MEG based on superconducting quantum interference devices (SQUID), MEG based on optically pump magnetometer (OPM) has the advantages of higher sensitivity, better spatial resolution and lower cost. However, most of the current studies are clinical studies, and there is a lack of animal studies on MEG based on OPM technology. Pain, a multifaceted sensory and emotional phenomenon, induces intricate alterations in brain activity, exhibiting notable sex differences. Despite clinical revelations of pain-related neuronal activity through MEG, specific properties remain elusive, and comprehensive laboratory studies on pain-associated brain activity alterations are lacking. The aim of this study was to investigate the effects of inflammatory pain (induced by Complete Freund’s Adjuvant (CFA)) on brain activity in a rat model using the MEG technique, to analysis changes in brain activity during pain perception, and to explore sex differences in pain-related MEG signaling. MethodsThis study utilized adult male and female Sprague-Dawley rats. Inflammatory pain was induced via intraplantar injection of CFA (100 μl, 50% in saline) in the left hind paw, with control groups receiving saline. Pain behavior was assessed using von Frey filaments at baseline and 1 h post-injection. For MEG recording, anesthetized rats had an OPM positioned on their head within a magnetic shield, undergoing two 15-minute sessions: a 5-minute baseline followed by a 10-minute mechanical stimulation phase. Data analysis included artifact removal and time-frequency analysis of spontaneous brain activity using accumulated spectrograms, generating spectrograms focused on the 4-30 Hz frequency range. ResultsMEG recordings in anesthetized rats during resting states and hind paw mechanical stimulation were compared, before and after saline/CFA injections. Mechanical stimulation elevated alpha activity in both male and female rats pre- and post-saline/CFA injections. Saline/CFA injections augmented average power in both sexes compared to pre-injection states. Remarkably, female rats exhibited higher average spectral power 1 h after CFA injection than after saline injection during resting states. Furthermore, despite comparable pain thresholds measured by classical pain behavioral tests post-CFA treatment, female rats displayed higher average power than males in the resting state after CFA injection. ConclusionThese results imply an enhanced perception of inflammatory pain in female rats compared to their male counterparts. Our study exhibits sex differences in alpha activities following CFA injection, highlighting heightened brain alpha activity in female rats during acute inflammatory pain in the resting state. Our study provides a method for OPM-based MEG recordings to be used to study brain activity in anaesthetized animals. In addition, the findings of this study contribute to a deeper understanding of pain-related neural activity and pain sex differences.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

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.

ObjectiveTo assess the relapse rate, clinical efficacy, and safety of a traditional Chinese medicine (TCM) sequential syndrome differentiation protocol for frequently relapsing/steroid-dependent nephrotic syndrome (FRNS/SDNS) in children. MethodsA total of 151 children with FRNS/SDNS treated in the First Affiliated Hospital of Henan University of Chinese Medicine from December 2020 to June 2024 were randomized into an observation group (77 cases) and a control group (74 cases). Both groups received Western medicine (prednisone tablets and tacrolimus capsules). In addition, the observation group additionally underwent TCM sequential syndrome differentiation and the control group received 1/10 of the TCM dose. The 6-month intervention was followed by a 12-month follow-up, totaling 18 months of observation across seven time points (before treatment and after 1, 2, 4, 24, 52, 76 weeks of treatment). The evaluation was carried out based on the following indicators. ① The relapse rates were mainly recorded after 24, 52, 76 weeks of treatment. ② The efficacy was evaluated based on the clinical remission rates after 1, 2, 4 weeks of treatment, the time to proteinuria clearance, the levels of 24-hour urine total protein (24-h UTP), serum total protein (TP), serum albumin (ALB), cholesterol (CHO), and triglycerides (TG) and the TCM symptom scores before treatment and after 24 weeks of treatment. ③ The treatment safety was evaluated based on blood routine and levels of liver enzymes, renal function indicators and blood glucose (Glu) before treatment and after 24 weeks of treatment. Results① Relapse rate: After 24 weeks of treatment, no significant difference in relapse rate was found between the two groups. The observation group showed lower relapse rates than the control group after 52 weeks of treatment [24.2% (16/66) vs. 52.5% (31/59), χ2=10.634, P<0.01] and 76 weeks of treatment [42.4% (28/66) vs. 74.6% (44/59), χ2=13.186, P<0.01] than the control group. ② Efficacy indicators: The two groups showed no significant difference in remission rate after 1 week of treatment. The observation group demonstrated higher remission rates after 2 weeks of treatment [88.2% (67/76) vs. 74.0% (54/73), Z=-1.999, P<0.05] and 4 weeks of treatment [94.7% (72/76) vs. 82.2% (60/73), Z=-2.3589, P<0.05). In addition, the observation group had shorter time to proteinuria clearance (P<0.01). After treatment, both groups showed declined 24 h-UTP, CHO, TG, and TCM symptom scores and elevated TP and ALB levels (P<0.01), and the observation group had lower CHO, TG, and TCM symptom scores and higher TP and ALB than the control group (P<0.05). ③ Safety indicators: After treatment, both groups showed declined white blood cell count (WBC), red blood cell count (RBC), hemoglobin (HB), and alanine aminotransferase (ALT) (P<0.05, P<0.01) and elevated Glu (P<0.01) and blood urea nitrogen (BUN) (P<0.05). After 24 weeks of treatment, none of WBC, RBC, HB, PLT, ALT, AST, BUN, Cr or Glu had significant differences between groups. Moreover, the incidence of adverse reactions showed no significant difference between the two groups. ConclusionThe TCM sequential syndrome differentiation protocol effectively reduces the relapse rate, improves the remission rate, shortens the time to proteinuria clearance, raised serum protein levels, lowers blood lipid levels, and alleviates symptoms, demonstrating good clinical safety in children with FRNS/SDNS.

Objective:To evaluate the mid-term efficacy of sleeve gastrectomy combined with single anastomosis gastric-ileal bypass (SASI) for treating gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG).Methods:Clinical data of 10 patients with post-LSG GERD undergoing SASI at the Department of Hernia and Bariatric Surgery, the First Affiliated Hospital of University of Science and Technology of China between Jan 2022 and Oct 2024 was retrospectively analyzed. Surgical safety and mid-term outcomes were evaluated.Results:The mean follow-up period was (25.40±17.33) months. The GerdQ score significantly decreased from (14.00±2.05) preoperatively to (5.70±1.49) postoperatively ( t=10.330, P<0.001), with a GERD remission rate of 90 % (9/10). Postoperative body weight and body mass index (BMI) both showed statistically significant reductions compared to preoperative values. Weight dropped from (110.29±22.92) kg to (84.95±15.89) kg ( t=5.889, P<0.001), and BMI decreased from (38.98±7.16) kg/m2 to (30.02±4.88) kg/m2 ( t=6.086, P<0.001). The percentage of excess weight loss was 65.88%±32.85%, and the percentage of total weight loss was 22.43%±9.65%. Only one patient experienced transient postoperative diarrhea, which resolved spontaneously, and no severe malnutrition cases were observed. Conclusion:SASI effectively improves GERD symptoms after LSG with favorable safety, serving as a suitable revisional surgical option for those patients.

Objective:To investigate the effect of exosomes released from triple-negative breast cancer cells (TNBC) on immune cells after radiotherapy.Methods:When TNBC (3 types: MDA-MB-231, MDA-MB-453, MDA-MB-468) reached 70% confluence, cells were irradiated with a dose of 8 Gy in one group and no intervention was given in the control group. The supernatants were collected at 48 h after irradiation. Subsequently, these supernatants were co-cultured with lymphocytes in peripheral blood mononuclear cells, and the uptake of exosomes by T cells was confirmed by fluorescence microscopy. Meanwhile, the expression of regulatory T cells (Treg) in the cells was detected using flow cytometry. Differences in Treg cell differentiation between two groups were compared by t-test (expressed as Treg cell positivity rate). Results:Transmission electron microscopy scanning and nanoparticle analysis showed that the extracellular vesicles extracted in the experiment were exosomes. Lymphocytes phagocytosed the exosomes and the exosomes were mainly concentrated in the cytoplasm after phagocytosis. Following the co-culture of 3 kinds of lymphocytes with exosomes from TNBC, there was an increase in Treg cell differentiation compared to control group (1.07%, 0.60%, 0.63% vs. 0.30%, P<0.01). In addition, exosomes released from TNBC further increased the differentiation of Treg cells after radiotherapy (MDA-MB-231 cells: 1.07% vs. 1.81%, P<0.01; MDA-MB-453 cells: 0.60% vs. 0.93%, P<0.05). Conclusions:In summary, exosomes released from TNBC can promote the differentiation of Treg cells. In addition, radiotherapy-induced exosomes released by TNBC further exacerbate the differentiation of Treg cell.

Sinusitis is a prevalent nasal disease in children, characterized by chronic and difficult-to-treat symptoms. Its onset is related to nasal stagnation, gallbladder and lung dysfunctions. This article explores the root cause based on Huangdi Neijing by considering the physiological and pathological characteristics of children. The core pathogenesis of pediatric sinusitis is the transmission of heat from the gallbladder and lung to the brain and nose, disrupting normal nasal function. Wind and heat pathogens often persist, accumulate, and transform into turbid qi, which are common triggers of the disease. Evil qi retention and yin depletion are internal factors that cause the prolonged and unhealed condition of the disease. This article emphasizes individualized treatment approaches based on disease duration and the severity of pathogenic factors. If external pathogens remain uncleared, treatment should focus on dispelling wind, clearing heat, dispersing with pungent medicinals, and dredging nasal orifices. If internal fire is exuberant, clearing lung qi, inhibiting hyperactive liver yang, and clearing exuberant fire should be used to relieve stagnation. In chronic cases with residual pathogens and liver-kidney yin deficiency, nourishing yin, clearing fire, and moistening the nasal orifices are essential. When exuberant heat has subsided, but the symptom of a persistent runny nose continues, leading to the loss of healthy qi and damage to the lung and spleen, treatments that tonify the spleen, benefit the lung, and reinforce healthy qi should be adopted to relieve stagnation. These treatments aim to restore the balance of the body′s vital qi by addressing both the lingering symptoms and the underlying weakness of the lung and spleen. The diagnosis and treatment of pediatric sinusitis based on the theory of "the transmission of heat from gallbladder and lung" can help reduce the recurrence of sinusitis and alleviate symptoms, with the aim of broadening the approach of traditional Chinese medicine in treating this condition.

Chinese Journal of School Health 2025;46(4):494-499
Objective:
To analyze the consumption frequency of major foods among Chinese children aged 6-17 years old, and to provide a basis for optimizing the dietary structure of children in China.
Methods:
Using data from the China Nutrition and Health System Survey and Application Program for Children 0-18 years old, 56 734 children aged 6-17 years old from North, Norththeast East, Central, South, Southwest and Northwest seven regions in China were selected for the study using stratified cluster random sampling from 2019 to 2021. A food frequency questionnaire was used to investigate the intake frequency of eight food groups in a month, including fresh vegetables, fresh fruits, livestock and poultry meats, aquatic products, eggs, dairy products, legumes, and cereals and potatoes. The foods were grouped according to whether they met the recommended intake criteria outlined in the Dietary Guidelines for Chinese Residents 2022. The〖KG*2〗χ2 test was used to compare the differences in the proportion of childrens intake frequency of each food group meeting the standard in different regions and age groups.
Results:
The proportions of Chinese children aged 6-17 years who consumed fresh vegetables and cereals and potatoes ≥3 times/d were 12.1% and 67.2%, respectively. The proportions of children who consumed fresh fruits, livestock and poultry meats, eggs and dairy products ≥1 time/d were 50.8%, 58.8%, 36.0% and 54.3%, respectively. The proportion of legumes consumed ≥4 times/week was 37.4%, and the proportion of aquatic products consumed ≥2 times/week was 39.7%. Fresh vegetables (5.5%), fresh fruits (33.1%), and dairy products (36.4%) had the lowest frequency of meeting the recommended standards in South China, and aquatic products (27.4%) and eggs (21.1%) had the lowest frequency of meeting the recommended standards in Northwest (P<0.008 3).
Conclusion
The overall intake frequency of fresh vegetables, fresh fruits, legumes, and dairy products are insufficient among Chinese children, with significant regional variations.
