Clinical characteristics and prognosis of 28 cases of infant acute lymphoblastic leukemia / 中华儿科杂志

Objective: To analyze the clinical characteristics and prognosis of patients with infant acute lymphoblastic leukemia (IALL). Methods: A retrospective cohort study.Clinical data, treatment and prognosis of 28 cases of IALL who have been treated at Beijing Children's Hospital, Capital Medical University and Baoding Children's Hospital from October 2013 to May 2023 were analyzed retrospectively. Based on the results of fluorescence in situ hybridization (FISH), all patients were divided into KMT2A gene rearrangement (KMT2A-R) positive group and KMT2A-R negative group. The prognosis of two groups were compared. Kaplan-Meier method and Log-Rank test were used to analyze the survival of the patients. Results: Among 28 cases of IALL, there were 10 males and 18 females, with the onset age of 10.9 (9.4,11.8) months. In terms of immune classification, 25 cases were B-ALL (89%), while the remaining 3 cases were T-ALL (11%). Most infant B-ALL showed pro-B lymphocyte phenotype (16/25,64%). A total of 22 cases (79%) obtained chromosome karyotype results, of which 7 were normal karyotypes, no complex karyotypes and 15 were abnormal karyotypes were found. Among abnormal karyotypes, there were 4 cases of t (9; 11), 2 cases of t (4; 11), 2 cases of t (11; 19), 1 case of t (1; 11) and 6 cases of other abnormal karyotypes. A total of 19 cases (68%) were positive for KMT2A-R detected by FISH. The KMT2A fusion gene was detected by real-time PCR in 16 cases (57%). A total of 24 patients completed standardized induction chemotherapy and were able to undergo efficacy evaluation, 23 cases (96%) achieved complete remission through induction chemotherapy, 4 cases (17%) died of relapse. The 5-year event free survival rate (EFS) was (46±13)%, and the 5-year overall survival rate (OS) was (73±10)%.The survival time was 31.3 (3.3, 62.5) months. There was no significant statistical difference in 5-year EFS ((46±14)% vs. (61±18)%) and 5-year OS ((64±13)% vs. (86±13)%) between the KMT2A-R positive group (15 cases) and the KMT2A-R negative group (9 cases) (χ2=1.88, 1.47, P=0.170, 0.224). Conclusions: Most IALL patients were accompanied by KMT2A-R. They had poor tolerance to traditional chemotherapy, the relapse rate during treatment was high and the prognosis was poor.

Fangji Fuling Decoction Alleviates Sepsis by Blocking MAPK14/FOXO3A Signaling Pathway / 中国结合医学杂志

OBJECTIVE@#To examine the therapeutic effect of Fangji Fuling Decoction (FFD) on sepsis through network pharmacological analysis combined with in vitro and in vivo experiments.@*METHODS@#A sepsis mouse model was constructed through intraperitoneal injection of 20 mg/kg lipopolysaccharide (LPS). RAW264.7 cells were stimulated by 250 ng/mL LPS to establish an in vitro cell model. Network pharmacology analysis identified the key molecular pathway associated with FFD in sepsis. Through ectopic expression and depletion experiments, the effect of FFD on multiple organ damage in septic mice, as well as on cell proliferation and apoptosis in relation to the mitogen-activated protein kinase 14/Forkhead Box O 3A (MAPK14/FOXO3A) signaling pathway, was analyzed.@*RESULTS@#FFD reduced organ damage and inflammation in LPS-induced septic mice and suppressed LPS-induced macrophage apoptosis and inflammation in vitro (P<0.05). Network pharmacology analysis showed that FFD could regulate the MAPK14/FOXO signaling pathway during sepsis. As confirmed by in vitro cell experiments, FFD inhibited the MAPK14 signaling pathway or FOXO3A expression to relieve LPS-induced macrophage apoptosis and inflammation (P<0.05). Furthermore, FFD inhibited the MAPK14/FOXO3A signaling pathway to inhibit LPS-induced macrophage apoptosis in the lung tissue of septic mice (P<0.05).@*CONCLUSION@#FFD could ameliorate the LPS-induced inflammatory response in septic mice by inhibiting the MAPK14/FOXO3A signaling pathway.

Clinicopathological features and prognostic factors of patients with lung metastasis of stage Ⅰa~Ⅲb cervical cancer / 中华肿瘤杂志

Objective: To investigate the clinicopathological features and prognostic factors of lung metastasis in patients with cervical cancer after treatment. Methods: The clinicopathological data of 191 patients with lung metastasis of stage Ⅰa-Ⅲb cervical cancer (FIGO 2009 stage) treated in Sichuan Cancer Hospital from January 2007 to December 2020 were analyzed retrospectively. Kaplan Meier method and Log rank test were used for survival analysis, and Cox regression model was used for prognostic factors analysis. Results: Among 191 patients with lung metastasis of cervical cancer, pulmonary metastasis was found in 134 patients (70.2%) during follow-up examination, and 57 patients (29.8%) had clinical symptoms (cough, chest pain, shortness of breath, hemoptysis, and fever). The time from the initial treatment of cervical cancer to the discovery of lung metastasis was 1-144 months in the whole group, with a median time of 19 months. Univariate analysis of the prognosis of lung metastasis after treatment of cervical cancer showed that the diameter of cervical tumor, lymph node metastasis, positive surgical margin, disease-free interval after treatment of cervical cancer, whether it is accompanied by other metastasis, the number, location and maximum diameter of lung metastasis, and the treatment method after lung metastasis are related to the prognosis of patients with lung metastasis of cervical cancer. Multivariate analysis showed that the number of lung metastases and other site metastases in addition to lung metastases were independent factors affecting the prognosis of patients with lung metastases of cervical cancer (P<0.05). Conclusions: For patients with cervical cancer, attention should be paid to chest CT examination during follow-up to guard against the possibility of lung metastasis after treatment. Besides lung metastasis, other site metastasis and the number of lung metastasis are independent factors affecting the prognosis of patients with lung metastasis of cervical cancer. For patients with lung metastasis after treatment of cervical cancer, surgical treatment is an effective treatment. It is necessary to strictly grasp the surgical indications, and some patients can achieve long-term survival. For patients with lung metastasis of cervical cancer who are not suitable for resection of lung metastasis, the remedial treatment of chemotherapy with or without radiotherapy is still a recommended choice.

Effect of Eltrombopag on Response to Immunosuppressive Therapy in Patients with Transfusion-Dependent Non-Severe Aplastic Anemia / 中国实验血液学杂志

OBJECTIVE@#To compare the efficacy of eltrombopag combined with cyclosporine A (CsA) and CsA alone in patients with transfusion-dependent non-severe aplastic anemia (TD-NSAA).@*METHODS@#The clinical data of 76 patients with treatment-naive TD-NSAA in Ningde Municipal Hospital of Ningde Normal University and Affiliated Hospital of Nantong University from December 2017 to June 2021 were retrospectively analyzed. Among them, 45 cases were treated with eltrombopag combined with CsA, and 31 patients with compatible baseline characters were treated with CsA alone. The efficacy of patients between the two groups was compared, and the factors affecting the curative effects were also analyzed.@*RESULTS@#There were significant differences in hematological response (HR) and complete response(CR) rates between the two groups at 3, 6, 12 months, and follow-up endpoint of treatment (P<0.05). With the prolongation of eltrombopag treatment time, the curative effect increased gradually, and the patients achieved more CR and HR rates by the end of the follow-up period. Simultaneously, with the increase in the maximum stable dose of eltrombopag, the HR rate increased gradually. The megakaryocyte count in eltrombopag group was higher than that in control at 6 and 12 months (P<0.05). Compared with the control group, the median time of platelet transfusion independence in eltrombopag group was more shorter (P=0.018), and the median platelets transfusion volume was lower (P=0.009). At 3, 6, 12 months after eltrombopag, the change of platelet in eltrombopag group was higher than that in the control group (P<0.05). Analysis of related factors affecting the efficacy showed that sex, age, iron overload, platelet count before treatment had no effect on the efficacy, and the median maximum stable dosage and the administration period for eltrombopag were related to the curative effect. The patients of eltrombopag group experienced adverse events of varying degrees, but the reactions were mild and mostly tolerated.@*CONCLUSION@#Eltrombopag can effectively improve the hematopoietic response and promote platelet recovery for TD-NSAA patients with relatively more residual hematopoietic cells, and it is safe and well tolerated.

Clinical Research Advances of Duodenal-Type Follicular Lymphoma--Review / 中国实验血液学杂志

Duodenal-type follicular lymphoma (DFL) is a unique subtype of follicular lymphoma (FL), which often involves the second portion of duodenum (descending part of duodenum). Due to its specific pathological features, such as lack of follicular dendritic cells meshwork and disappearance of activation-induced cytidine deaminase expression, DFL presents an inert clinical course and is often confined to the intestinal tract. Inflammation-related biomarkers suggest that the microenvironment may play a likely role in the pathogenesis and favorable prognosis of DFL. Since patients generally have no obvious clinical symptoms and low progression rate, the treatment regimen for DFL is mainly observation and waiting (W&W) strategy. This study will review the latest research progress of epidemiology, diagnosis, treatment and prognosis of DFL in recent years.

Omics Analysis of Ferroptosis and Establishment of Prognostic Model for multiple myeloma Patients / 中国实验血液学杂志

OBJECTIVE@#To explore the role of ferroptosis-related genes in multiple myeloma(MM) through TCGA database and FerrDb, and build a prognostic model of ferroptosis-related genes for MM patients.@*METHODS@#Using the TCGA database containing clinical information and gene expression profile data of 764 patients with MM and the FerrDb database including ferroptosis-related genes, the differentially expressed ferroptosis-related genes were screened by wilcox.test function. The prognostic model of ferroptosis-related genes was established by Lasso regression, and the Kaplan-Meier survival curve was drawn. Then COX regression analysis was used to screen independent prognostic factors. Finally, the differential genes between high-risk and low-risk patients were screened, and enrichment analysis was used to explore the mechanism of the relationship between ferroptosis and prognosis in MM.@*RESULTS@#36 differential genes related to ferroptosis were screened out from bone marrow samples of 764 MM patients and 4 normal people, including 12 up-regulated genes and 24 down-regulated genes. Six prognosis-related genes (GCLM, GLS2, SLC7A11, AIFM2, ACO1, G6PD) were screened out by Lasso regression and the prognostic model with ferroptosis-related genes of MM was established. Kaplan-Meier survival curve analysis showed that the survival rate between high risk group and low risk group was significantly different(P<0.01). Univariate COX regression analysis showed that age, sex, ISS stage and risk score were significantly correlated with overall survival of MM patients(P<0.05), while multivariate COX regression analysis showed that age, ISS stage and risk score were independent prognostic indicators for MM patients (P<0.05). GO and KEGG enrichment analysis showed that the ferroptosis-related genes was mainly related to neutrophil degranulation and migration, cytokine activity and regulation, cell component, antigen processing and presentation, complement and coagulation cascades, haematopoietic cell lineage and so on, which may affect the prognosis of patients.@*CONCLUSION@#Ferroptosis-related genes change significantly during the pathogenesis of MM. The prognostic model of ferroptosis-related genes can be used to predict the survival of MM patients, but the mechanism of the potential function of ferroptosis-related genes needs to be confirmed by further clinical studies.

Gut microbiota as a target for traditional Chinese medicine in the treatment of cardiovascular disease: potential mechanisms and therapy strategies / 药学学报

Cardiovascular disease (CVD) is a major contributor to patient deaths worldwide, and its pathogenesis is complex and mortality rates are increasing every year. Numerous researches have shown that the gut microbiota and its metabolites were closely associated with the development of CVD, and gut microbiota was expected to be a potential new target for the treatment of CVD. Traditional Chinese medicine (TCM), characterized by its multi-component, multi-target and integrity, can play a therapeutic role in CVD by regulating the gut microbiota, which has obvious advantages in stabilizing the disease, improving heart function and enhancing quality of life, and is an ideal intestinal microecological regulator. Therefore, this review will mainly discuss the intimate association of gut microbiota and its metabolites with CVD, and the therapeutic strategies of TCM targeting gut microbiota to improve CVD, including regulating the composition of gut microbiota, protecting the intestinal mucosal barrier, influencing the intestinal immune function and modulating the metabolites of gut microbiota, in order to provide a reference for the research of TCM targeting gut microbiota for CVD.

Impact of sinonasal anatomic changes after endoscopic anterior skull base surgery on nasal airflow and air conditioning: a computational fluid dynamics study / 中华耳鼻咽喉头颈外科杂志

Objective: To analyze the impact of the sinonasal anatomic changes after endonasal endoscopic anterior skull base surgery on the nasal airflow and heating and humidification by computational fluid dynamics (CFD), and to explore the correlation between the postoperative CFD parameters and the subjective symptoms of the patients. Methods: The clinical data in the Rhinology Department of the First Affiliated Hospital of Zhengzhou University from 2016 to 2021 were retrospectively analyzed. The patients received the endoscopic resection of the anterior skull base tumor were selected as the case group, and the adults whose CT scans had no sinonasal abnormalities were chosen as the control group. The CFD simulation was performed on the sinonasal models after reconstructed from the patients' sinus CT images during the post-surgical follow-up. All the patients were asked to complete the Empty Nose Syndrome 6-Item Questionnaire (ENS6Q) to assess the subjective symptoms. The comparison between two independent groups and the correlation analysis were carried out by using the Mann-Whitney U test and the Spearman correlation test in the SPSS 26.0 software. Results: Nineteen patients (including 8 males and 11 females, from 22 to 67 years old) in the case group and 2 patients (a male of 38 years old and a female of 45 years old) in the control group were enrolled in this study. After the anterior skull base surgery, the high-speed airflow moved to the upper part of the nasal cavity, and the lowest temperature shifted upwards on the choana. Comparing with the control group, the ratio of nasal mucosal surface area to nasal ventilation volume in the case group decreased [0.41 (0.40, 0.41) mm-1 vs 0.32 (0.30, 0.38) mm-1; Z=-2.04, P=0.041], the air flow in the upper and middle part of the nasal cavity increased [61.14 (59.78, 62.51)% vs 78.07 (76.22, 94.43)%; Z=-2.28, P=0.023], the nasal resistance decreased [0.024 (0.022, 0.026) Pa·s/ml vs 0.016 (0.009, 0.018) Pa·s/ml; Z=-2.29, P=0.022], the lowest temperature in the middle of the nasal cavity decreased [28.29 (27.23, 29.35)℃ vs 25.06 (24.07, 25.50)℃; Z=-2.28, P=0.023], the nasal heating efficiency decreased [98.74 (97.95, 99.52)% vs 82.16 (80.24, 86.91)%; Z=-2.28, P=0.023], the lowest relative humidity decreased [(79.62 (76.55, 82.69)% vs 73.28 (71.27, 75.05)%; Z=-2.28, P=0.023], and the nasal humidification efficiency decreased [99.50 (97.69, 101.30)% vs 86.09 (79.33, 87.16)%; Z=-2.28, P=0.023]. The ENS6Q total scores of all patients in the case group were less than 11 points. There was a moderate negative correlation between the proportion of the inferior airflow in the post-surgical nasal cavity negatively and the ENS6Q total scores (rs=-0.50, P=0.029). Conclusions: The sinonasal anatomic changes after the endoscopic anterior skull base surgery alter the nasal airflow patterns, reducing the efficiency of nasal heating and humidification. However, the post-surgical occurrence tendency of the empty nose syndrome is weak.

OBJECTIVE To investigate the effect and mechanism of α7 nicotinic acetylcholine receptor （α7nAChR） agonists PNU-282987 on cognitive function in temporal lobe epilepsy （TLE） model rats. METHODS Sixty rats were randomly divided into control group， model group， PNU-282987 group （3 mg/kg） and methyllycaconitine （MLA）+PNU-282987 group （6 mg/kg MLA+3 mg/kg PNU-282987）， with 15 rats in each group. Except for control group， the TLE model was established in the other groups. After the model was successfully established， each group was given relevant medicine or normal saline intraperitoneally， once a day， for two consecutive weeks. The epilepsy attack of rats was observed and scored， and the duration of seizures was recorded； the cognitive function of rats was detected； pathological morphology of neurons in CA1 region was observed； the levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6） and IL-1β in the hippocampus were detected； the positive expressions of ionized calcium-binding adapter molecule-1 （IBA-1）， α7nAChR， nuclear factor-κB （NF-κB） p65， p-NF-κB p65 in the hippocampus were detected. RESULTS Compared with model group， the score and duration of seizures， the number of IBA-1 positive cells， the levels of TNF- α， IL-6 and IL-1β， the expressions of NF- κB p65 and p-NF- κB p65 protein decreased significantly in the hippocampus （P＜0.05）； the escape latency time was shortened significantly （P＜0.05）， the time spent in the original platform quadrant and times of crossing the platform increased significantly （P＜0.05）； neuronal damage in the CA1 region of the hippocampus was significantly reduced； the expression of α7nAChR protein increased significantly in hippocampus （P＜0.05）. Compared with PNU-282987 group， the above indexes of rats in MLA+PNU-282987 group were reversed significantly （P＜0.05）. CONCLUSIONS PNU-282987 could improve cognitive dysfunction in TLE model rats， and its mechanism may be associated with inhibiting microglia-mediated inflammatory response through α7nAChR/NF- κB signaling pathway， thus reducing hippocampal neuronal damage.

Predictive value of anticardiolipin antibody and D-dimer combined with risk assessment profile for thromboembolism for deep vein thrombosis in elderly postoperative patients with intertrochanteric fracture of femur / 中国医师进修杂志

Objective:To investigate the predictive value of anticardiolipin antibody (ACA) and D-dimer (D-D) combined with risk assessment profile for thromboembolism (RAPT) for deep vein thrombosis (DVT) in elderly postoperative patients with intertrochanteric fracture of femur (IFF).Methods:The clinical data of 123 elderly patients with IFF in Suzhou Hospital Affiliated to Anhui Medical University from January 2019 to March 2022 were retrospectively analyzed. All patients underwent closed reduction intramedullary nail fixation. The patients were divided into DVT group (27 cases) and non-DVT group (96 cases) according to the presence or absence of DVT 7 d after surgery. Before surgery and 3, 5 d after operation, the ACA was detected by enzyme-linked immunosorbent assay, the D-D was detected by automatic coagulation analyzer, and RAPT was performed. The correlation among ACA, D-D and RAPT was analyzed by Spearman method. Multivariate Logistic regression was used to analyze the independent risk factors of DVT in elderly postoperative patients with IFF. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of ACA, D-D and RAPT in predicting DVT in elderly postoperative patients with IFF. The incidences of postoperative DVT in patients with different ACA, D-D and RAPT patients were compared.Results:There were no statistical difference in ACA, D-D and RAPT before operation between the two groups ( P>0.05); the ACA, D-D and RAPT 3 and 5 d after operation in DVT group were significantly higher than those in the non-DVT group, 3 d after operation: (12.44 ± 3.25) × 10 3 RU/L vs. (8.67 ± 2.81) × 10 3 RU/L, (7.29 ± 1.49) mg/L vs. (4.70 ± 1.23) mg/L and (9.79 ± 1.15) scores vs. (9.21 ± 1.32) scores; 5 d after operation: (10.28 ± 2.16) × 10 3 RU/L vs. (6.45 ± 2.04) × 10 3 RU/L, (5.49 ± 1.26) mg/L vs. (3.63 ± 1.05) mg/L and (9.57 ± 1.08) scores vs. (9.12 ± 0.70) scores, and there were statistical differences ( P<0.01 or <0.05). Since ACA, D-D and RAPT in the two groups all reached their peak 3 d after operation, this time point was selected for analysis. Three days after operation, Pearson correlation analysis result showed that ACA and D-D were positively correlated with RAPT ( r = 0.635 and 0.630, P<0.01), and ACA was positively correlated with D-D ( r = 0.657, P<0.01). ROC curve analysis result showed that the area under the curve (AUC) of ACA and D-D combined RAPT 3 d after operation in predicting DVT in elderly postoperative patients with IFF was greater than that predicted by the 3 indexes alone (0.982 vs. 0.894, 0.870 and 0.868), the optimal cut-off values were 11.48 × 10 3 RU/L, 6.75 mg/L and 9 scores. According to the optimal cut-off value of ROC curve analysis at 3 d after operation, the patients were divided into ACA low expression (≤11.48 × 10 3 RU/L, 92 cases) and ACA high expression (>11.48 × 10 3 RU/L, 31 cases), D-D low expression (≤6.75 mg/L, 99 cases) and D-D high expression (>6.75 mg/L, 24 cases), low RAPT (≤9 scores, 93 cases) and high RAPT (>9 scores, 30 cases). The incidences of postoperative DVT in patients with ACA high expression, D-D high expression and high RAPT were significantly higher than those in patients with ACA low expression, D-D low expression and low RAPT: 43.39% (15/31) vs. 13.04% (12/92), 54.17% (13/24) vs. 14.14% (14/99) and 53.33% (16/30) vs. 11.83% (11/93), and there were statistical differences ( χ2 = 16.91, 18.06 and 22.81; P<0.01). After controlling for diabetes and other factors, multivariate Logistic regression analysis result showed that ACA, D-D and RAPT 3 d after operation were independent risk factors for DVT in elderly postoperative patients with IFF ( OR = 2.156, 2.276 and 6.106; 95% CI 1.356 to 3.429, 1.240 to 4.177 and 1.564 to 23.840; P<0.01). Conclusions:The ACA, D-D combined with RAPT can improve the predictive value of DVT in elderly postoperative patients with IFF, which has important reference significance for taking timely and effective intervention measures in early clinical stage.

Research progress of perineural invasion in gallbladder cancer / 中华消化外科杂志

As a special mode of tumor metastasis, perineural invasion has been paid more and more attention. It is closely related to prognosis, recurrence and metastasis of tumor after surgery. As the most common malignancy of the biliary tract, perineural invasion is also an inde-pendent prognostic risk factor for gallbladder cancer due to its anatomical location, lymphatic reflux, blood perfusion and innervation. However, there are few studies on perineural invasion in gallbla-dder cancer, especially on its mechanism. By analyzing the general situation and recent progress of perineural invasion in gallbladder cancer, the authors mainly introduce the perineural invasion mechanism, perineural invasion rate of gallbladder cancer, relationship between perineural invasion and the clinical pathologic characteristic, the correlation with the prognosis, relationship with surgi-cal procedures and postoperative adjuvant therapy.

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Structure-based drug discovery of novel fused-pyrazolone carboxamide derivatives as potent and selective AXL inhibitors

As a novel and promising antitumor target, AXL plays an important role in tumor growth, metastasis, immunosuppression and drug resistance of various malignancies, which has attracted extensive research interest in recent years. In this study, by employing the structure-based drug design and bioisosterism strategies, we designed and synthesized in total 54 novel AXL inhibitors featuring a fused-pyrazolone carboxamide scaffold, of which up to 20 compounds exhibited excellent AXL kinase and BaF3/TEL-AXL cell viability inhibitions. Notably, compound 59 showed a desirable AXL kinase inhibitory activity (IC50: 3.5 nmol/L) as well as good kinase selectivity, and it effectively blocked the cellular AXL signaling. In turn, compound 59 could potently inhibit BaF3/TEL-AXL cell viability (IC50: 1.5 nmol/L) and significantly suppress GAS6/AXL-mediated cancer cell invasion, migration and wound healing at the nanomolar level. More importantly, compound 59 oral administration showed good pharmacokinetic profile and in vivo antitumor efficiency, in which we observed significant AXL phosphorylation suppression, and its antitumor efficacy at 20 mg/kg (qd) was comparable to that of BGB324 at 50 mg/kg (bid), the most advanced AXL inhibitor. Taken together, this work provided a valuable lead compound as a potential AXL inhibitor for the further antitumor drug development.

Efficacy and safety of Kangxian Huanji Granule as adjunctive treatment in acute exacerbation of idiopathic pulmonary fibrosis: An exploratory randomized controlled trial / 中西医结合学报

BACKGROUND@#Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is an important occurrence in the natural history of idiopathic pulmonary fibrosis (IPF), associated with high hospitalization rates, high mortality and poor prognosis. At present, there is no effective treatment for AE-IPF. Chinese herbal medicine has some advantages in treating IPF, but its utility in AE-IPF is unclear.@*OBJECTIVE@#The treatment of AE-IPF with Kangxian Huanji Granule (KXHJ), a compound Chinese herbal medicine, lacks an evidence-based justification. This study explores the efficacy and safety of KXHJ in patients with AE-IPF.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS@#We designed a randomized, double-blind, placebo-controlled, exploratory clinical trial. A total of 80 participants diagnosed with AE-IPF were randomly assigned to receive KXHJ or a matching placebo; the treatment included a 10 g dose, administered twice daily for 4 weeks, in addition to conventional treatment. Participants were followed up for 12 weeks after the treatment.@*MAIN OUTCOME MEASURES@#The primary endpoints were treatment failure rate and all-cause mortality. Secondary endpoints included the length of hospitalization, overall survival, acute exacerbation rate, intubation rate, the modified British Medical Research Council (mMRC) score, and the St George's Respiratory Questionnaire for IPF (SGRQ-I) score.@*RESULTS@#The rate of treatment failure at 4 weeks was lower in the intervention group compared to the control group (risk ratio [RR]: 0.22; 95% confidence interval [CI]: 0.051 to 0.965, P = 0.023). There was no significant difference in all-cause mortality at 16 weeks (RR: 0.75; 95% CI: 0.179 to 3.138; P > 0.999) or in the acute exacerbation rate during the 12-week follow-up period (RR: 0.69; 95% CI: 0.334 to 1.434; P = 0.317). The intervention group had a shorter length of hospitalization than the control group (mean difference [MD]: -3.30 days; 95% CI, -6.300 to -0.300; P = 0.032). Significant differences in the mean change from baseline in the mMRC (between-group difference: -0.67; 95% CI: -0.89 to -0.44; P < 0.001) and SGRQ-I score (between-group difference: -10.36; 95% CI: -16.483 to -4.228; P = 0.001) were observed after 4 weeks, and also in the mMRC (between-group difference: -0.67; 95% CI: -0.91 to -0.43; P < 0.001) and SGRQ-I (between-group difference: -10.28; 95% CI, -15.838 to -4.718; P < 0.001) at 16 weeks. The difference in the adverse events was not significant.@*CONCLUSION@#KXHJ appears to be effective and safe for AE-IPF and can be considered a complementary treatment in patients with AE-IPF. As a preliminary exploratory study, our results provide a basis for further clinical research.@*TRIAL REGISTRATION@#Chinese Clinical Trial Registry (ChiCTR1900026289).

Intellectual status and factors influencing the intelligence in children with attention deficit and hyperactive disorder / 中国当代儿科杂志

OBJECTIVES@#To study the intellectual level and the factors influencing the intelligence in children aged 6-16 years with attention deficit hyperactivity disorder (ADHD).@*METHODS@#A retrospective study was conducted on 2 861 children who were diagnosed with ADHD according to the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition between October 2014 and September 2022 at Henan Children's Hospital. The Wechsler Intelligence Scale for Children-Fourth Edition was used to assess the intellectual levels of the ADHD children. Based on intelligence quotient (IQ) scores, the intellectual levels were classified into five categories: borderline (70-79), low average (80-89), average (90-109), high average (110-119), and superior (≥120). The intellectual levels among the children of different genders, grades, and parental education levels were compared.@*RESULTS@#Among the 2 861 ADHD children, 569 (19.89%) were classified as borderline, 846 (29.57%) as low average, 1 304 (45.58%) as average, 111 (3.88%) as high average, and 31 (1.08%) as superior. The boys had lower scores in working memory, processing speed, and overall IQ than the girls (P<0.05). There were significant differences in perceptual reasoning, working memory, processing speed, and overall IQ scores among different grade groups (P<0.05). The scores in language comprehension, perceptual reasoning, working memory, processing speed, and overall IQ were found to be associated with parental education level in ADHD children (P<0.05).@*CONCLUSIONS@#The proportion of ADHD children with low average and borderline intellectual levels is relatively high. The IQ level of ADHD children is influenced by gender, grade level and parental education level.

Application of body temperature rinse in percutaneous transforaminal endoscopic lumbar discectomy through intervertebral approach / 中国骨伤

OBJECTIVE@#To investigate the effects of two types of temperature rinses on body temperature, inflammatory cytokine levels, and bleeding volume in percutaneous endoscopic lumbar discectomy.@*METHODS@#Eighty patients underwent percutaneous endoscopic lumbar discectomy from January 2018 to December 2020 were selected and divided into experimental group (40 cases) and control group(40 cases). In experimental group, there were 19 males and 21 females, aged (38.8±9.8) years old;7patients on L4,5 and 33 patients on L5S1;Body msss index(BMI) was (27.8±7.2) kg·m-2. In contral group, there were 18 males and 22 females, aged (41.5±10.9) years old, 5 patients on L4,5 and 35 patients on L5S1;BMI was (26.4±6.2) kg·m-2. The patients in the control group were received normal saline rinse at room temperature, and the patients in the experimental group were received normal saline rinse heated to 37 ℃. Body temperature, chills, nausea, vomiting, and other adverse reactions were recorded. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10) in two groups were recorded before and 2 hours after operation. Visual analogue scale (VAS) was used to evaluate the degree of lumbar pain in two groups before and 2 hours after surgery. Fibrinolytic-coagulation indexes with preoperative and 2 hours after surgery, including the D-dimer (DD), fibrinogen degradation products (FDP), activated partial thrombin time (APTT) and prothrombin time (PT) were recorder. Operation time and blood loss in two groups were recorded.@*RESULTS@#The body temperature of both groups showed a downward trend, while the body temperature of the control group was lower than that of the experimental group. The levels of TNF-α, IL-6 and IL-10 in two groups were increased 2 hours after surgery compared with those before surgery(P<0.05), while the levels in experimental group were lower than those in control group(P<0.05). Postoperative VAS in experimental group 2.19±1.13 was significantly lower than that in the control group 3.38±1.35(P<0.05). The levels of DD and FDP at 2 hours after surgery in both groups were higher than those before surgery (P<0.05), while the levels of DD and FDP in the experimental group were higher than those in the control group (P<0.05). There was no significant difference in APTT and PT levels between two groups after operation (P>0.05). The blood loss in the experimental group of (45.2±14.1) ml was lower than that in the control group of (59.52±15.6) ml. The operation time of experimental group (46.7±13.8) min was less than that of control group (58.3±15.2) min(P<0.05).@*CONCLUSION@#Body temperature rinse can reduce the incidence of adverse reactions, alleviate local inflammatory reactions, reduce intraoperative blood loss and shorten the operation time.
