The health of the human body is the result of the dynamic interplay between immunity and various microorganisms. Furthermore, the health of the mitochondrial grid determines the strength of immunity. Mitochondrial imbalance leads to the metabolic remodeling of intracellular nutrients, which accelerates the occurrence and development of tumors. The theory of yin and yang and the theory of visceral outward manifestation are the foundation and core of traditional Chinese medicine (TCM) theory, which guides the clinical diagnosis and treatment of TCM. Yang Qi is the driving force behind the metabolism and physiological functions of the human body; it is also the adenine nucleoside triphosphate produced efficiently by mitochondrial aerobic respiration. The main transport of spleen refers to the biological oxidation process of food in the mitochondria, and its normal function is closely related to the integrity of the mitochondrial structure and function of the cell. Therefore, warming yang and strengthening the spleen essentially means restoring the high production capacity of the mitochondria. Rebuilding damaged mitochondrial function, improving efficiency, and boosting the energy level of the neuro-endocrine-immune network are the key factors contributing to the body’s ability to resist disease and return to health.

Guanylate binding protein subunit β-2(GNB2)is an important part of G protein family.In the process of cell signal transduction,GNB2 plays a structural support and regulatory role in G protein complex,ensuring the correct transmission and amplification of signals,interacting with receptors and regulating vari-ous effector enzymes and ion channels,and mediating a variety of physiological functions.Therefore,GNB2 plays a key role in cell signaling,and participates in the regulation of cell proliferation,differentiation and mi-gration and other biological processes.This article reviews the research progress of GNB2,focusing on its structure,function,regulatory mechanism,disease correlation and importance in tumor research.

Type 2 diabetes mellitus(T2DM)is a metabolic disease characterized by insulin resistance,and is one of the most common chronic non-communicable diseases worldwide.In the field of traditional Chinese medicine(TCM),yang deficiency causing diabetes is one of the important pathogenetic mechanisms of T2DM and contributes to the core pathological basis of insulin resistance.Guided by the theory of yang deficiency causing diabetes,this paper reviewed the relevant domestic literature issued in recent years,sorted out western medical pathogenesis and treatment for insulin resistance in T2DM,TCM theory of yang deficiency causing diabetes and its clinical application,and the clinical efficacy of TCM for the treatment of insulin resistance,and then explored the applicability of theory of yang deficiency causing diabetes for TCM treatment of insulin resistance in T2DM.It is concluded that TCM treatment for insulin resistance in T2DM based on the theory of yang deficiency causing diabetes has significant efficacy and advantages,for it realizes the integration of advantages of TCM and western medicine and achieves the synergistic actions through keeping the scientific nature and standardization of western medicine and by maintaining the advantages of holism and individualization of TCM treatment.TCM treatment for insulin resistance is effective on improving insulin signal transduction,insulin secretion function and other related metabolic abnormalities indicators through multiple pathways and targets,thus to improve the health status of the body.TCM treatment for insulin resistance exerts good safety and tolerance,and can reduce the incidence of adverse reactions caused by western medicine.However,the research on TCM treatment for insulin resistance still has the insufficiencies such as low quality of clinical trials,unclear therapeutic mechanism,and lack of innovation and pioneering.Further relevant research needs to be carried out in-depth,so as to provide a scientific basis for TCM to play a greater role in preventing and treating metabolic diseases.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a patient with Weiss-Kruszka syndrome (WSKA). METHODS: A male patient presented with primary infertility for 1 year post-marriage, intellectual disability, and blepharoptosis at Huzhou Maternity and Child Health Care Hospital from October to December 2024 was selected as the study subject. Peripheral blood samples were collected from the patient and his family members. Following extraction of genomic DNA, whole-exome sequencing (WES) was carried out. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. This study was approved by the Ethics Committee of the Hospital (Ethics No. 2023-R-010). RESULTS: The patient, a 29-year-old male, had exhibited short stature, trigonocephaly, bilateral blepharoptosis, arched eyebrows, brachydactyly, redundant skin folds, webbed neck, hypertrichosis, mild intellectual disability, and speech impairment. WES revealed that he has harbored a de novo heterozygous frameshifting variant of the ZNF462 gene, namely c.945_946del (p.T316Rfs*42). Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PM2_Supporting+PVS1+PM6_Supporting). CONCLUSION The ZNF462 c.945_946del variant probably underlay the WSKA in this patient. Above finding has enriched the mutational spectrum of the ZNF462 gene.

To investigate the levels and clinical significance of serum microRNA ( miR) -146a, miR-145, T-helpertype17 (Th17)/regulatory T cell (Treg) in children with respiratory syncytial virus (RSV) infectious pneumonia. The clinical data of 200 children with RSV infectious pneumonia admitted to Nantong Maternal and Child Health Hospital from June 2020 to June 2023 were retrospectively collected as the study group. At the same time, 200 children with mycoplasma pneumonia were selected as the common pneumonia group and 200 healthy children were selected as the healthy group. The levels of serum inflammatory factors [interleukin-6 (IL-6), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α)] were detected by enzyme-linked immunosorbent assay. The expression levels of serum miR-146a and miR-145 were detected by RT-qPCR. The levels of Th17/Treg were detected by flow cytometry. The levels of miR-146a, miR-145, Th17/Treg and serum inflammatory factors were compared among the three groups. Pearson method was used to analyze the correlation between miR-146a, miR-145, Th17/Treg and serum inflammatory factors in children with RSV infectious pneumonia. The receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic value of miR-146a, miR-145, Th17/Treg in children with respiratory syncytial virus infection pneumonia. The results showed that in the study group, miR-146a (2.01±0.58), miR-145 (1.81±0.46), Th17/Treg (1.09±0.31), IL-6 (7.82±2.11) ng/L and TNF-α (9.82±2.96) ng/L were higher than those in the common pneumonia group miR-146a (1.49±0.42), miR-145 (1.43±0.31), Th17/Treg (0.77±0.24), IL-6 (5.89±1.32) ng/L, TNF-α (7.34±2.32) ng/L and healthy group miR-146a (1.25±0.19), miR-145 (1.19±0.16), Th17/Treg (0.38±0.09), IL-6 (4.52±1.04) ng/L, TNF-α (5.39±1.07)ng/L. The levels of the above indexes in the common pneumonia group were higher than those in the healthy group, and the differences were statistically significant ( F=183.543, 175.938, 617.182, 226.657, 193.459, P<0.05). In the study group, IFN-γ (14.18±3.25) pg/ml was lower than that in the control group (19.52±5.13) pg/ml, but higher than that in the healthy group (9.77±2.40) pg/ml, and the difference was statistically significant ( F=335.432, P<0.05). Pearson correlation analysis showed that miR-146a, miR-145 and Th17/Treg were positively correlated with IL-6 and TNF-α ( P<0.05), but negatively correlated with IFN-γ ( P<0.05). ROC curve results showed that the area under the curve (AUC) of miR-146a, miR-145 and Th17/Treg in the diagnosis of RSV infectious pneumonia was 0.767, 0.762 and 0.790, respectively, while the combined detection of the three was 0.904. In conclusion, the levels of miR-146a, miR-145 and Th17/Treg are highly expressed in children with RSV infectious pneumonia, and are closely related to the inflammatory response of children. The combined detection of the three may have certain application value in the auxiliary diagnosis of RSV infectious pneumonia.

Objective To evaluate the clinical benefit of caffeine treatment regimen determined based on oxygen discontinuation as target orientation for oxygen-dependent preterm infants.Methods A total of 219 preterm infants admitted to the neonatal department of this hospital from October 2021 to September 2023 were selected and divided into the intervention group (caffeine treatment targeting weaning oxygen,n=108) and the control group (routine caffeine treatment,n=111).The differences in the apnea recurrence,reuse of caffeine,time of caffeine discontinuation,duration of using oxygen and hospitalization duration were compared between the two groups.Results Compared with the control group,the correcting fetal age by stopping caffe-ine in the intervention group was greater[(35.9±1.7)weeks vs.(34.4±1.5)weeks],hospitalization dura-tion was longer[(64.62±20.60)d vs.(57.96±17.68)d],and the differences were statistically significant (P<0.05).The apnea recurrence rate,reuse rate of caffeine,duration of oxygen use,incidence rate of moder-ate to severe bronchopulmonary dysplasia,mechanical ventilation use rate,hospitalization expenses,≥grade Ⅱ necrotizing enterocolitis,feeding intolerance,tachycardia incidence rate and body weight increase velocity had no statistical differences between the two groups (P>0.05).Conclusion Determining the caffeine treatment course regimen by oxygen discontinuation as target orientation could not reduce the recurrent risk of preterm infants apnea recurrence risk,which could prolong the hospitalization duration.

Objective:To investigate the clinical, radiological, and pathological features of anaplastic gangliogliomas (AGGs) and to determine whether these tumors represent a distinct entity.Methods:Consecutive 667 cases of ganglioglioma (GG) diagnosed at the Xuanwu Hospital, Capital Medical University, Beijing, China between January 2015 and July 2023 were screened. Among these cases, 9 pathologically confirmed AGG cases were identified. Their clinical, radiological, treatment, and outcome data were analyzed retrospectively. Most of the tumor samples were subject to next-generation sequencing, while a subset of them were subject to DNA methylation profiling.Results:Among the 9 patients, there were five males and four females, with a median age of 8 years. Epileptic seizures (5/9) were the most frequently presented symptom. Radiological examinations showed three types of radiological manifestations: four cases showed abnormal MRI signals with no significant mass effects and mild enhancement; two cases demonstrated a mixed solid-cystic density lesion with peritumoral edema, which showed significant heterogeneous enhancement and obvious mass effects, and one case displayed cystic cavity formation with nodules on MRI, which showed evident enhancements. All cases exhibited mutations that were predicted to activate the MAP kinase signaling pathway, including seven with BRAF p.V600E mutation and two with NF1 mutation. Five AGGs with mutations involving the MAP kinase signaling pathway also had concurrent mutations, including three with CDKN2A homozygous deletion, one with a TERT promoter mutation, one with a H3F3A mutation, and one with a PTEN mutation.Conclusions:AGG exhibits a distinct spectrum of pathology, genetic mutations and clinical behaviors, differing from GG. Given these characteristics suggest that AGG may be a distinct tumor type, further expansion of the case series is needed. Therefore, a comprehensive integration of clinical, histological, and molecular analyses is required to correctly diagnose AGG. It will also help guide treatments and prognostication.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.
