Colorectal cancer （CRC） ranks as the second leading cause of cancer death worldwide. Although preventive colonoscopy screening has improved the survival rate of CRC patients in the past few years， there are still many patients diagnosed after symptoms appear. The surgery for CRC carries high risks and high recurrence， and ideal therapies remain to be developed. The Janus kinase/signal transducer and activator of transcription （JAK/STAT） signaling pathway has become a focus of research due to its central role in cellular activities. As a classic oncogenic pathway， the JAK/STAT signaling pathway offers new possibilities for diagnosing and treating various malignancies， and it paves a new way for developing therapies for CRC. This pathway not only participates in basic cellular processes， such as proliferation， differentiation， and apoptosis but also plays a crucial role in immune responses and inflammation. Abnormal activation of the JAK/STAT signaling pathway is closely related to the occurrence and development of CRC. Studies have shown that the active components and compound prescriptions of traditional Chinese medicine （TCM） can inhibit the proliferation， invasion， migration， and angiogenesis while promoting the apoptosis and autophagy of CRC cells by interfering with the JAK/STAT signaling pathway. Furthermore， this pathway may also play a role in regulating the sensitivity of tumor cells to chemotherapy and radiotherapy， thus influencing the effectiveness of tumor treatment and impeding the progression of CRC. In recent years， research results have been updated rapidly， and previous literature summaries have failed to incorporate the latest findings， creating obstacles to accessing current literature. Therefore， this article supplements and summarizes information from the definition of the JAK/STAT pathway， association of this pathway with CRC， and TCM intervention of CRC. This review aims to provide references for future development of molecular biology regarding CRC and the research and development of new drugs.

A retrospective analysis of the clinical data of seven acute B-lymphoblastic leukemia (B-ALL) patients with TCF3-HLF fusion gene-positive admitted to the First Affiliated Hospital of Soochow University from June 2017 to August 2022 was conducted to summarize their clinical features and prognoses. The seven B-ALL patients comprised four males and three females, with a median age of 18 (11-33) years. Five patients tested positive for CD33 expression, and four patients had a normal karyotype. Two patients had hypercalcemia at the initial diagnosis, and one patient developed hypercalcemia at relapse. Six patients presented with coagulation dysfunction at diagnosis. After induction chemotherapy, five out of seven patients achieved complete remission, of which four subsequently relapsed. Two patients did not achieve remission even after two rounds of induction chemotherapy, with one achieving complete remission after treatment with blinatumomab immunotherapy. Three patients underwent chimeric antigen receptor T cell therapy, whereas three patients subsequently underwent hematopoietic stem cell transplantation. Five patients died, while two patients survived with sustained complete remission. TCF3-HLF-positive B-ALL is rare and has a high relapse rate and poor prognosis.

Objective:To explore the predictive value of helper T cell(Th)immune response indicators for asthma control in children with cough variant asthma(CVA)and its relationship with the risk of recurrence.Methods:A total of 112 children with CVA in Hengshui City People's Hospital from August 2020 to August 2021 were selected,all received conventional western medicine treat-ment,and were divided into well-controlled group(n=85)and poorly-controlled group(n=27)according to their asthma control status after 4 weeks of treatment.compare the general data,pulmonary function indexes before treatment[forced expiratory volume in 1 se-cond(FEV1),FEV1/forced vital capacity(FVC)],Th immune response indexes(Th1/Th2,IL-2,IFN-γ,IL-4,IL-10)levels,ana-lyze the correlation between Th immune response indicators and pulmonary function indicators,and predict the value of asthma control in children with CVA.After 6 months of follow-up,the recurrence situation in the well-controlled group was counted,the Th immune response indexes before treatment were compared between the children with recurrence and those without recurrence,and the relation-ship between Th immune response indexes and recurrence were analyzed.Results:Before treatment,the levels of FEV1,FEV1/FVC,Th1/Th2,IL-2 and IFN-γ in the poor control group were lower than those in the well-controlled group,and the levels of IL-4 and IL-10 were higher than those in the well-controlled group(P<0.05).Th1/Th2,IL-2,IFN-γ levels were positively correlated with FEV1,FEV1/FVC before treatment in children with CVA,and IL-4,IL-10 levels were negatively correlated with FEV1,FEV1/FVC(P<0.05);the areas under the curve(AUC)of Th1/Th2,IL-2,IFN-γ,IL-4 and IL-10 levels before treatment for predicting poor asthma control in children with CVA were all>0.7,and the combined predicted AUC(0.933)was the largest;before treatment,the levels of Th1/Th2,IL-2 and IFN-γ in the relapsed children in the group were lower than those of the non-relapsed children,and the levels of IL-4 and IL-10 were higher than those of the non-relapsed children(P<0.05);The levels of Th1/Th2,IL-2,and IFN-γ before treat-ment were negatively correlated with CVA recurrence,while IL-4 and IL-10 levels were positively correlated with CVA recurrence(P<0.05).Conclusion:Th immune response index has a certain value in predicting asthma control in children with CVA,and is closely related to the recurrence of CVA.

OBJECTIVE To establish the HPLC fingerprint of Xintongshu spray， determine the contents of identified components， and investigate the transferring patterns of the index components of decoction pieces， intermediates and spray， so as to provide scientific reference for technology management and quality control of Xintongshu spray. METHODS HPLC fingerprints of 13 batches of Xintongshu spray were established by the Similarity Evaluation System for Chromatographic Fingerprints of TCM （2012 edition）， and common peaks were identified； the contents of identified components were determined by HPLC. The paeonol in Moutan Cortex and ferulic acid in Chuanxiong Rhizoma were used as index components to investigate the transferring patterns of them in decoction pieces， intermediates and spray. RESULTS There were a total of 33 common peaks in the fingerprints of 13 batches of Xintongshu spray， and the similarities were more than 0.994. Eight components were identified， i.e. gallic acid （peak 5）， oxypaeoniflorin （peak 9）， chlorogenic acid（peak 10）， caffeic acid （peak 14）， paeoniflorin （peak 17）， ferulic acid （peak 21）， senkyunolide Ⅰ （peak 27） and paeonol （peak 31）. The contents of 8 components ranged from 0.590 3- 0.719 7， 0.565 7-0.851 3， 0.279 4-0.368 1， 0.080 6-0.106 1， 1.922 5-3.033 5， 0.151 3-0.191 6， 0.250 6-0.336 0， 3.056 7-4.161 0 mg/mL， respectively. The average transfer rates of paeonol and ferulic acid from decoction pieces to sprays were 63.76% and 38.06%， respectively. It was also found that the process in which the loss of paeonol was more than 30% was the extraction by percolation and negative pressure concentration of Moutan Cortex. The process in which the loss of ferulic acid was more than 50% was the steam distillation extraction process of Chuanxiong Rhizoma. CONCLUSIONS The established HPLC fingerprint and content determination method of Xintongshu spray are reproducible and specific. The key processes that cause a decrease in the average transfer rates of the index components are the extraction by percolation and negative pressure concentration of Moutan Cortex and steam distillation extraction of Chuanxiong Rhizoma.

Objective: Due to the complicated compounds and the synergistic effect of multi-compounds, the quality control and assessment of Chinese materia medica (CMM) encounters a great challenge about how to identify the key compounds, which are directly correlated with its efficacy and safety. On the guidance of study on quality marker (Q-Marker), identification of Q-Markers was performed from Hedan Tablet (HDT) by the aid of the “spider-web” mode and hepatotoxicity evaluation derived from our previous researches and literatures. Methods: By the established ultra performance liquid chromatography with photodiode array detector (UPLC-PDA) method, online UPLC-DPPH· and offline antioxidant assay, 21 candidate compounds of HDT were systematically investigated and comprehensively evaluated by the “spider-web” mode for them properties of Q-Marker based on “content-stability-activity”. In addition, the Q-Markers related with hepatotoxicity based on our previous researches and literatures were identified. Results: Salvianolic acid B (SaB), quercetin-3-O-glucuronide (Qug), isoquercitrin (IQ) and hyperoside (Hyp) were adopted as the preferable Q-Markers of HDT according to the shaded area (A) of tested compounds in “spider-web” mode. Psoralen (Ps), isopsoralen (IP), psoralenoside (PO) and isopsoralenoside (IPO) were also strongly recommended as Q-Markers closely related with safety by considering hepatotoxicity of the accumulated Ps and IP and conversion between glycoside (PO and IPO) and aglycone (Ps and IP). Conclusion: This study provided scientific evidence for quality control and assessment of HDT, and also provided a meaningful reference for application of Q-Markers in CMM.
