Electrical impedance tomography (EIT) represents an emerging medical functional imaging technology, which operates by applying safe-to-human excitation currents through surface-mounted electrodes, measuring boundary voltages between electrodes, and selecting appropriate image reconstruction algorithms to visualize resistivity in tomographic cross-sections. Compared to traditional medical imaging techniques, EIT offers non-invasive and radiation-free operation, high sensitivity to tissue resistivity changes, and superior temporal resolution, meeting the real-time requirements of clinical dynamic condition monitoring. This paper comprehensively reviews the research status of brain EIT technology, systematically summarizes its advantages and technical limitations in perioperative applications, and prospectively forecasts future development directions of perioperative brain EIT based on current research foundations and clinical application demands, with the aim of providing methodological references for further optimization and clinical promotion of this technology.

eIF3a is a N ⁶-methyladenosine (m⁶A) reader that regulates mRNA translation by recognizing m⁶A modifications of these mRNAs. It has been suggested that eIF3a may play an important role in regulating translation initiation via m⁶A during infection when canonical cap-dependent initiation is inhibited. However, the death of animal model studies impedes our understanding of the functional significance of eIF3a in immunity and regulation in vivo. In this study, we investigated the in vivo function of eIF3a using eIF3a knockout and knockdown mouse models and found that eIF3a deficiency resulted in splenic tissue structural disruption and multi-organ damage, which contributed to severe sepsis induced by Lipopolysaccharide (LPS). Ectopic eIF3a overexpression in the eIF3a knockdown mice rescued mice from LPS-induced severe sepsis. We further showed that eIF3a maintains a functional and healthy immune system by regulating B cell function and quantity through m⁶A modification of mRNAs. These findings unveil a novel mechanism underlying sepsis, implicating the pivotal role of B cells in this complex disease process regulated by eIF3a. Furthermore, eIF3a may be used to develop a potential strategy for treating sepsis.

Objective:To investigate the risk factors and their predictive efficacy for postoperative premature epiphyseal closure in pediatric patients with distal tibial epiphyseal fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 216 pediatric patients with distal tibial epiphyseal fractures admitted to Zhengzhou Orthopedics Hospital from January 2018 to December 2023, including 136 males and 80 females, aged 2-16 years [11.8(9.8, 13.3)years]. Among them, 112 patients were affected on the left side and 104 on the right. According to the Salter-Harris fracture classification, the fracture was classified as type I in 14 patients, type II in 97, type III in 38, type IV in 64 and type VI in 3. According to the presence of premature epiphyseal closure after surgery, the patients were divided into premature epiphyseal closure group ( n=38) and normal epiphyseal group ( n=178). Age, gender, body mass index (BMI), injury mechanism, side of injury, Salter-Harris classification of fracture, initial displacement distance of the fracture end, medial malleolar involvement by the fracture line surgical fixation method, operation duration, reduction method, and reduction quality were recorded in the two groups. Univariate analysis and binary Logistic regression analysis were used to evaluate and determine the independent risk factors for postoperative premature physeal closure in pediatric patients with distal tibial epiphyseal fracture. The receiver operating characteristic (ROC) curve was plotted and area under the curve (AUC) was calculated to evaluate the predictive efficacy of each risk factor for the occurrence of premature physeal closure in pediatric patients with distal tibial epiphyseal fractures. Results:Univariate analysis showed the occurrence of postoperative premature epiphyseal closure of the distal tibia was associated with age, Salter-Harris fracture classification, medial malleolar involvement by the fracture line, surgical fixation method, reduction method, and reduction quality ( P<0.05), while it was not correlated with gender, BMI, injury mechanism, side of injury, initial displacement distance of the fracture end, and operation duration ( P>0.05). Multivariate binary Logistic regression analysis showed that medial malleolar involvement by the fracture line ( OR=0.18, 95% CI 0.04, 0.76, P<0.05) and reduction quality ( OR=43.18,95% CI 10.71, 174.05, P<0.01) were significantly correlated with the occurrence of postoperative premature epiphyseal closure of the distal tibia. The results of ROC curve analysis showed that medial malleolar involvement by the fracture line had limited predictive efficiency (AUC=0.53, 95% CI 0.43, 0.63), reduction quality had moderate predictive efficacy (AUC=0.81, 95% CI 0.72, 0.91), while their combination demonstrated even higher predictive efficacy (AUC=0.83, 95% CI 0.74, 0.91). Conclusions:Medial malleolar involvement by the fracture line and reduction quality are independent risk factors for postoperative premature epiphyseal closure in pediatric patients with distal tibial epiphyseal fractures. Reduction quality demonstrates good predictive efficacy, while medial malleolar involvement by the fracture line shows limited predictive value. The combination of both factors achieves even better predictive performance.

The Huangdi Neijing proposes the " using bitter herbs to nourish or purge" theory to guide clinical prescription and formulation of herbal remedies based on the physiological characteristics and functions of the five zang viscera, along with the properties and flavors of medicinal herbs. This study explored diabetic kidney disease pathogenesis and treatment based on the " using bitter herbs to nourish or purge" theory. Kidney dryness is a key pathological factor in diabetic kidney disease, and the disharmony of kidney dryness is an essential aspect of its pathogenesis. Strengthening is the primary therapeutic principle, and kidney dryness is a persistent factor throughout the occurrence and progression of diabetic kidney disease. In the early stage, the pathogenesis involves heat-consuming qi and injuring yin, leading to kidney dryness. In the middle stage, the pathogenesis manifests as qi deficiency and blood stasis in the collaterals, resulting in turbidity owing to kidney dryness. In the late stage, the pathogenesis involves yin and yang deficiency, with kidney dryness and disharmony. This study proposes the staging-based treatment based on the " need for firmness" characteristic of the kidney. The aim is to provide new insights for clinical diagnosis and treatment in traditional Chinese medicine by rationally using pungent, bitter, and salty medicinal herbs to nourish and moisturize the kidney. This approach seeks to promote precise syndrome differentiation and personalized treatment for different stages of diabetic kidney disease, thereby enhancing clinical efficacy.

The paper summarizes Professor YANG Jun's thoughts on clinical treatment with acupuncture and moxibustion. Professor YANG Jun puts forward the "refined mode for diagnosis and treatment of diseases with acupuncture and moxibustion", aiming to improve the capacity of diagnosis and treatment in clinical practice. He advocates that the diagnosis and treatment should be guided by the identification of etiologies, syndromes and meridians; in accordance with regulating the shape/form, balancing yin and yang, and harmonizing the mind; and by means of skillful techniques of acupuncture and moxibustion, simplified selection of acupoints and delicate manipulations. Besides, he stresses on the combination of multiple techniques of acupuncture (such as penetrating technique with long needle, stuck needling by lifting and pulling, and micro-acupuncture systems) with moxibustion techniques (moxibustion for resolving stasis and unblocking collaterals, pressing moxibustion, borneol moxibustion, moxibustion with medicinal plaster) in clinical practice, so as to enhance the therapeutic effects.

This article systematically summarizes the clinical experience of Professor Yang Jun,a nationally renowned traditional Chinese medicine(TCM)physician,in applying refined direct moxibustion(applying a moxibustion pen made by Chinese medical extract)to treat functional dyspepsia(FD)of the stuffiness-fullness type.Based on decades of clinical practice,Professor Yang innovatively established a moxibustion therapy system for FD,which centers on TCM syndrome differentiation and treatment.The system emphasizes the refined identification of epigastric stuffiness and fullness syndrome,particularly focusing on the relative significance of abdominal distension and poor appetite.Its therapeutic features lie in establishing the principle of"prioritizing mind regulation while holistically harmonizing body and spirit",combined with personalized moxibustion dosage control and a unique refined direct moxibustion technique.By optimizing the configuration of each step in moxibustion therapy,the system maximizes therapeutic efficacy,providing novel theoretical foundations and clinical strategies for moxibustion treatment of stuffiness-fullness type of FD.

This article introduces Professor Yang Jun's clinical experience in treating bronchial asthma using warming needle moxibustion via the governor vessel-unblocking and conception vessel-regulating method.Professor Yang posits that asthma pathogenesis-whether triggered by internal imbalances or external pathogens-ultimately stems from yin-yang disharmony leading to rebellious lung qi and impaired diffusion/descending functions.Thus,restoring dynamic yin-yang balance constitutes the core therapeutic principle.As the governor and conception vessels govern the body's yin-yang regulation,Professor Yang's decades of clinical practice substantiate that"harmonizing these vessels determines life's vitality".His protocol combines warming needle moxibustion with press needles to activate governor-conception vessel functions,achieving five therapeutic effects:(1)yin-yang harmonization,(2)qi movement regulation,(3)meridian unblocking,(4)visceral stabilization,and(5)pathogen elimination,demonstrating remarkable efficacy.

Objective To observe the clinical efficacy of Yishen Huoxue Decoction combined with acupuncture in treating premature ovarian insufficiency(POI)with kidney deficiency and blood stasis syndrome.Methods A total of 116 patients diagnosed with POI of kidney deficiency and blood stasis syndrome who attended the outpatient department of Sichuan North Medical College Affiliated Nanchong Traditional Chinese Medicine Hospital between April 2023 and October 2024 were selected as study subjects.Patients were randomly divided into an observation group and a control group using a random number table,with 58 cases in each group.The control group received sequential therapy with estrogen and progesterone,while the observation group received Yishen Huoxue Decoction combined with acupuncture in addition to the control group's treatment.The treatment was administered continuously for three menstrual cycles.After three months of treatment,the clinical efficacy of both groups was evaluated.Changes in TCM syndrome scores,serum hormone levels[follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),anti-Müllerian hormone(AMH)],immune factors[interleukin-2(IL-2),tumor necrosis factor-α(TNF-α),interferon-γ(IFN-γ)],and protein expression levels of the PI3K/AKT signaling pathway were observed and compared between the two groups before and after treatment.Safety and adverse reactions were also evaluated.Results(1)The total effective rate was 91.38％(53/58)in the observation group and 74.14％(43/58)in the control group.The efficacy of the observation group was significantly superior to that of the control group,with a statistically significant difference(P＜0.05).(2)After treatment,TCM syndrome scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(3)After treatment,serum levels of FSH,E2,LH,and AMH were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(4)After treatment,levels of IFN-γ,TNF-α,and IL-2 were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(5)After treatment,the protein expression levels of PI3K and AKT were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(6)During treatment,the incidence of adverse reactions was 10.34％(6/58)in the observation group and 8.62％(5/58)in the control group.There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Based on the theory of"waxing and waning transformation of yin and yang",Yishen Huoxue Decoction combined with acupuncture significantly improves clinical symptoms,regulates the immune microenvironment,activates the PI3K/AKT signaling pathway,and effectively enhances ovarian function in patients with POI of kidney deficiency and blood stasis syndrome,demonstrating notable clinical efficacy.

Objective:To review the application of internet cognitive behavioral therapy (CBT) in perinatal women with negative emotions, point out the limitations of existing studies, and put forward development suggestions for future research.Methods:Using the Scope review guide published by Joanna Briggs Institute as the methodological framework, eight Chinese and English databases including China National Knowledge Infrastructure (CNKI), Wanfang, PubMed and Web of Science were searched until July 1, 2024, and the literatures were collected and analyzed.Results:A total of 18 literatures were included. The interventionists of internet cognitive behavioral therapy were mostly psychologists; the intervention methods were mostly in the form of partial participation of therapists, and the intervention platforms were mostly websites. The intervention content was centered on mental health education, emotional monitoring, cognitive reconstruction, behavioral activation training, and problem solving. There were 15 studies that demonstrated that internet cognitive behavioral therapy was effective, and three studies showed that internet cognitive behavioral therapy was not effective in improving negative emotions in perinatal women, but perinatal women responded to treatment.Conclusions:The Internet cognitive behavioral therapy can effectively improve the negative emotions of perinatal pregnant women, but the long-term effect is not clear. Future studies can expand the sample size and follow up the effect for a long time.

Objective:To investigate the clinical effectiveness of tumor lesion curettage and allogeneic bone grafting via the fovea of femoral head through the surgical hip dislocation approach in children and adolescents with femoral head chondroblastoma (FHCB).Methods:Case series study.The clinical data of 7 FHCB patients [3 males and 4 females with a mean age of 13.7 years (11-19 years)] treated at the Department of Pediatric Orthopedics, Zhengzhou Orthopedic Hospital from January 2016 to March 2023 were retrospectively analyzed.All patients underwent lesion curettage and allogeneic bone grafting via the fovea of femoral head through the surgical hip dislocation approach.The healing, local recurrence and complications were assessed via clinical and radiological tests.Functional outcomes were evaluated using the Musculoskeletal Tumour Society (MSTS) scoring system.A paired t-test was used to compare the MSTS scores before the operation and at the final follow-up. Results:All patients were followed up for 30 months on average (18-48 months).The average healing time for bone grafting was 4.9 (3-8) months.Local recurrence and serious postoperative complications such as avascular necrosis of femoral head, secondary osteoarthritis, ectopic ossification and nonunion of greater trochanter osteotomy end were not observed in all patients up to the last follow-up.The average MSTS score at the last follow-up was (29.14±0.45) points.Conclusions:Curettage and bone grafting via the fovea of femoral head through the surgical hip dislocation approach is effective and safe in the treatment of FHCB in children and adolescents.This method can maintain the integrity of the articular surface and growth plate, and also preserve the blood supply of the femoral head and the normal function of the hip joint, with satisfactory short-term effects.
