The brain-gut interaction theory is a multidimensional integrative concept based on the brain-gut axis， involving neural， endocrine， and immune regulatory networks as well as the gut microbiota. Zang-fu organs （脏腑） theory in traditional Chinese medicine （TCM） shows a high degree of consistency with the brain-gut interaction theory， and the core functions such as the spleen and stomach governing the ascending of the clear and descending of the turbid， the liver governing the free flow of qi， and the heart governing mental and emotional activities are closely associated with the multi-level regulatory mechanisms of the brain-gut axis. TCM therapy can modulate brain-gut interactions through multiple pathways in the treatment of spleen and stomach diseases， including the regulation of gastrointestinal hormone secretion， neurotransmitter levels， the hypothalamic-pituitary-adrenal （HPA） axis， immune homeostasis and inflammatory responses， as well as the gut microecology. However， current basic research on the brain-gut interaction theory in TCM for spleen and stomach diseases still faces several challenges， such as difficulties in integrating TCM spleen-stomach theory with modern pathophysiology， lack of innovation in research concepts， and limitations in research methodologies. It is therefore proposed that multidisciplinary collaboration， multi-omics technologies， and targeted research approaches should be adopted to provide more comprehensive methods for basic research on TCM spleen and stomach diseases， thereby promoting the in-depth development of brain-gut interaction theory.

Objective To retrospective analysis summarized the effectiveness and safety of the"triple"conversion therapy regimen combining immune,targeted and local therapy.Methods From February 2019 to June 2023,52 patients with advanced liver cancer from February 2019 to June 2023 in XI,an Jiao Tong university medicine college affiliated 3201 hospital were admitted and received conversion treatment regimens combining sintilimab with bevacizumab and combined with local treatment,analyzed the surgical resection rate and pathological complete response rate(pCR),complete response rate(CR),partial response rate(PR),progression of disease(PD),stable disease(SD),objective response rate(ORR)and disease control rate(DCR).To evaluated the effect of conversion therapy and adverse reactions.Results 21 cases had recived operative resection in the 52 patients with primary liver cancer receiving sintilimab and bevacizumab.The postoperative resection rate was 40.4％(21/52),pCR 42.9％(9/21).The other 31 cases have complete response 5.8％(3/52),PR 25.0％(13/52),PD 11.5％(6/52),SD 17.3％(9/52).The overall objective response rate(ORR)was71.2％(37/52),and the disease control rate(DCR)was 88.5％(46/52).Adverse reactions manifest as Grade 1-2 skin-related damage primarily affecting the epidermis.Conclusions For patients with potentially resectable primary liver cancer in middle and advanced stage,the"triple"conversion therapy with sintilimab combined with bevacizumab as systematic treatment and combined with local therapy can achieve good conversion treatment effect with controllable safety.

Objective:To explore the application value of four-dimensional ultrasound combined with maternal serological screening in fetal facial deformities.Methods:A total of 106 pregnant women at mid pregnancy,whose fetuses with suspected fetal facial deformities and who conducted prenatal screening in Sanya Maternal and Child Health Hospital(Sanya Women and Children's Hospital)from January 2020 to December 2022,were selected.All of them underwent four-dimensional ultrasound and maternal serological screening.The results of delivery or induced labor were used as the gold standard of diagnosis to compare the diagnostic values of single four-dimensional ultrasound,single maternal serological screening and the combination of them for fetal facial deformities.Results:The analysis of the receiver operating characteristic(ROC)curve showed that the area under curve(AUC)values of four-dimensional ultrasound,maternal serological screening and the combination of them were respectively 0.932,0.863 and 0.981 in diagnosing fetal facial deformities.Both the sensitivities and accuracies of four-dimensional ultrasound and maternal serological screening were significantly lower than those of the combined diagnosis of them in diagnosing fetal facial deformities,and the differences of them were statistical significance(x2=11.173,0.064,P<0.05),respectively.Conclusion:Four-dimensional ultrasound combines with maternal serological screening can improve the diagnostic accuracy for fetal facial deformities.

Immune repertoire is defined as the sum of T cells and B cells, which possesses high diversity and enables immune system to respond to various antigen stimuli. With the development of sequencing technique, immune repertoire sequencing can be utilized to deeply understand the changes of lymphocyte clones when rejection occurs at the gene level, and also provide the possibility for the emergence of novel non-invasive diagnostic techniques based on immune repertoire sequencing. In recent years, more and more attempts have been made to apply immune repertoire sequencing in solid organ transplantation, especially in the fields of kidney transplantation, liver transplantation, heart transplantation and post-transplantation infection. In this article, research progresses on the application of immune repertoire sequencing in these fields were reviewed, and current status of immune repertoire sequencing in organ transplantation and its potential as a novel technique for early non-invasive diagnosis of rejection were summarized, aiming to provide reference for subsequent development and clinical application of this technique.

OBJECTIVE To analyse the prognosis and laryngeal function retention of patients undergoing minimally invasive and open surgery after induction chemotherapy.METHODS The clinical data of 54 hypopharyngeal carcinoma patients who received induction chemotherapy and underwent laryngeal preservation surgery in Beijing Tongren Hospital from 2016 to 2022 were retrospectively analyzed.The laryngeal function recovery and survival rate were compared between the two groups.RESULTS Twenty-eight patients underwent transoral minimally invasive surgery and 26 patients underwent partial laryngectomy and/or partial laryngectomy via external cervical approach.The 3-year survival rates of the two groups were 63%and 59%,respectively,and the difference was not statistically significant(P＞0.05).The differences were statistically significant(P＜0.05).CONCLUSION In patients with downstaged hypopharyngeal carcinoma after induction chemotherapy,the survival rate of transoral minimally invasive surgery is similar to that of open surgery,and the laryngeal function recovery of transoral minimally invasive surgery is better.
