Lung cancer is the malignant tumor with the highest incidence and mortality rates globally. Current treatment methods for lung cancer primarily include surgery， chemotherapy， targeted therapy， and immunotherapy. However， the main limitations of these treatments are their side effects， the drug resistance， and the economic burden they impose. As a critical cancer pathway， the Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathway regulates tumor occurrence and development through multiple mechanisms by influencing various downstream targets. Consequently， the JAK/STAT signaling pathway offers a promising avenue for lung cancer treatment research. Numerous studies have demonstrated that the JAK/STAT signaling pathway plays a key role in the proliferation and growth of lung cancer cells， angiogenesis， epithelial-mesenchymal transition （EMT）， metabolic alterations， remodeling of the immune microenvironment， and the development of treatment resistance. Traditional Chinese medicine （TCM） has garnered increasing attention due to its minimal side effects， low economic burden， and its potential to enhance efficacy and reduce toxicity when used in conjunction with Western medicine. In addition to traditional Chinese medicine compounds， a growing number of Chinese medicine monomers have come into the spotlight because of their more targeted effects. Numerous studies investigating the regulation of the JAK/STAT signaling pathway by TCM in the treatment of lung cancer have demonstrated that TCM can inhibit the proliferation and invasion of lung cancer cells， tumor angiogenesis， and EMT， improve the inflammatory and immunosuppressive microenvironments， and enhance treatment sensitivity by intervening in the JAK/STAT signaling pathway， thereby impeding the progression of lung cancer. In recent years， the research on the regulation of this pathway by TCM in the treatment of lung cancer has been updated rapidly. However， the summary of these studies has not been updated in time. This review summarizes and reflects on the recent research findings regarding the regulation of the JAK/STAT signaling pathway by TCM to intervene in lung cancer from three aspects， introducing the JAK/STAT pathway， elaborating the mechanism of this pathway in lung cancer， and exploring the intervention of TCM in the treatment of lung cancer through this pathway， to provide more reference for the treatment of lung cancer in the future.

Objective:To screen genetic and epigenetic expression differences associated with pulmonary embolism through integrated bioinformatics analysis.Methods:Four patients with pulmonary embolism and healthy physical examination in the Third Affiliated Hospital of Xinjiang Medical University in 2019 were selected as the research objects, using high-throughput sequencing technologies and methylation chip technology to detect, screening and integrated peripheral blood difference genomes and the epigenome data to identify the pathogenesis of pulmonary embolism caused by methylation of drive and differentially expressed genes, GO and KEGG enrichment analysis were performed.Results:Coexpression analysis of DNA methylation and gene expression data between the pulmonary embolism group and the healthy control group showed that differential methylation in the upstream region of genes was negatively correlated with gene expression. Among them, 8 significantly methylated genes in the upstream region of genes were screened out, and independent sample t-test and Pearson correlation analysis were done. In the pulmonary embolism group, there were 6 significant methylated genes of TSS1500, namely TSPO2, C1QA, AQP1, TNFSF9, MIA and STAB1, and the differential expression multiple log2FC of corresponding genes was 1.298, 1.629, 1.024, 2.746, 2.539, 1.060, respectively. The correlation between gene expression and gene methylation were -0.908, -0.900, -0.824, -0.784, -0.783, -0.779, respectively, and the methylation differences between the two groups were -0.049, -0.053, -0.048, -0.057, -0.050, respectively. -0.053 ( P < 0.05). There were three significantly methylated genes in the TSS200 region, namely TSPO2, SLC9A, and SIGLEC1. The gene expression differential multiple log2FC was 1.298, -2.252, and 1.866, respectively. The correlation between gene expression and gene methylation was -0.860, -0.774, and -0.739, respectively. The methylation difference between the two groups was -0.051, 0.027, -0.048 ( P < 0.05). In the pulmonary embolism group, 7 genes, including TSPO2, C1QA, AQP1, TNFSF9, MIA, STAB1 and SIGLEC1, showed hypomethylation and high expression in the TSS region. SLC9A3 gene showed high methylation and low expression. In the analysis of GO function, significant enrichment was obtained in complement activation, immune response and activation protein cascade. In the KEGG signaling pathway, the immune system, bacterial infection, and signaling molecules and interactions are significantly enriched, thereby regulating the occurrence of pulmonary embolism. Conclusions:Based on the combined analysis of DNA methylation and gene expression, a new idea of the occurrence and development of pulmonary embolism has been found, which can be further studied in the future.

Objective:To investigate the antibacterial and osteogenic properties of biomimetic mineralized iodine-loaded coating with micro-nano topography on the surface of bone implants.Methods:After the fiber network structure of sodium hydrogen titanate was constructed by alkali thermal reaction on the surface of Ti6Al4V (noted as AT), it was biomimetically mineralized in the modified simulated body fluid to form a micro-nano topology with high specific surface area (noted as AT-CaP), and finally loaded with PVPI to construct a novel antibacterial osseointegration coating (noted as AT-CaP-PVPI). The study was conducted in AT, AT-CaP, and AT-CaP-PVPI groups, in each of which 3 parallel experiments were performed. The morphology and colony counting of Staphylococcus aureus on the coating surface were observed to detect the in vitro antibacterial performance of the coating. Fifteen male SD rats were randomly divided into 3 groups ( n=5): AT, AT-CaP, and AT-CaP-PVPI. After intramedullary injection of Staphylococcus aureus into the lower end of the femur in the SD rats, titanium rods coated with AT, AT-CaP, and AT-CaP-PVPI were inserted into the marrow cavity. The osteogenesis, volume ratio of new bone mass and number of trabeculae on the surface of the femoral implants were compared between the 3 groups 4 weeks after operation. Results:In AT and AT-CaP groups, a large number of bacteria grew in their inherent elliptical or spherical shape on the implant surface and a large number of colonies were seen on the plate; in AT-CaP-PVPI group, the bacteria on the coating surface exhibited membrane deformation and depression, some of them were completely broken and dissolved, and a large number died. There was almost no new bone formation around the implants in AT group; new bone scattered around the implants with discontinuous distribution in AT-CaP group; a great amount of new bone was seen around the implants with even distribution but no signs of infection in AT-CaP-PVPI group. The volume ratio of new bone mass and the number of trabeculae on the implant surface in AT-CaP-PVPI group were 0.453±0.206 and 6.055±0.536, respectively, significantly higher than those in AT group (0.046±0.028 and 1.667±1.249) and AT-CaP group (0.188±0.052 and 3.804±0.889) ( P<0.05). Conclusion:Biomimetic mineralized iodine-loaded coating with micro-nano topography on the surface of bone implants shows good antibacterial and osteogenic properties.

Objective:To investigate the effects of early sleep deprivation(SD) on depressive-like behavior and hippocampus synaptic plasticity in adult mice with chronic unpredictable mild stress(CUMS) model.Methods:Thirty 2-week-old clean grade male mice were randomly divided into control group (CON group), CUMS group and SD + CUMS group according to the random number table, with 10 mice in each group. The mice in SD + CUMS group were subjected with sleep deprivation for 4 hours once a day during puberty (3 ~ 6 weeks old), and then were stimulated by CUMS after adulthood (9 weeks old). The mice in CUMS group were subjected with CUMS at the age of 9 weeks. And the mice in CON group were not given any intervention.The depressive-like behavior was evaluated by body weight, sugar water preference, tail suspension test and forced swimming test.The density of dendritic spines of basal and apical neurons in hippocampal CA1 was measured by Golgi staining, the frequency and amplitude of miniature excitatory postsynaptic current(mEPSC) of pyramidal neurons in the hippocampal CA1 region of mice were measured by electro-physiological patch clamp technique.Graphpad prism 7.0 software was used for statistical analysis and mapping. One-way ANOVA was used for comparison among multiple groups, and Tukey test was used for further pairwise comparison.Results:(1) After stress modeling, there were significant differences in body weight, sugar water preference percentage, forced swimming immobility time and tail suspension time among the three groups ( F=71.63, 39.82, 44.13, 43.07, all P<0.01). Compared with CON group, the mice in CUMS group and SD+ CUMS group had lower body weight ((25.51±0.37) g, (22.92±0.31) g, (20.12±0.27) g, both P<0.01), lower sugar water percentage preference ((87.40±1.65) %, (63.42±3.33) %, (49.68±3.70)%, both P<0.01), longer immobile time of forced swimming ((34.30±5.32) s, (119.20±12.03) s, (153.80±9.17) s, both P<0.01) and longer immobile time of tail suspension test((115.20±8.19)s, (156.80±4.35) s, (192.00±4.12) s, both P<0.01). Compared with CUMS group, SD+ CUMS group had lower body weight ( P<0.01), lower sugar water preference percentage ( P<0.05), longer immobile time in forced swimming test( P<0.05) and longer immobile time in tail suspension test( P<0.01). (2) Golgi staining results showed that the densities of dendritic spines of apical neurons and basal neurons in hippocampal CA1 area of the three groups were significantly different ( F=38.41, 41.34, both P<0.01). The densities of dendritic spines of basal and apical hippocampal neurons in CUMS group and SD+ CUMS group were lower than those in CON group ((7.74±0.22)/10 μm, (6.58±0.27)/10 μm, (5.00±0.13)/10 μm, both P<0.01), ((8.90±0.23)/10 μm, (7.63±0.30)/10 μm, (6.01±0.14)/10 μm, both P<0.01). Compared with CUMS group, the mice in SD+ CUMS group had lower densities of dendritic spines of basal and apical hippocampal neurons(both P<0.01). (3) Electrophysiological results showed that there were significant differences in the frequency and amplitude of mEPSC in hippocampal pyramidal neurons of the three groups ( F=38.90, 63.37, both P<0.01). Compared with CON group, the frequency and amplitude of mEPSC in pyramidal neurons of CA1 in CUMS group and SD+ CUMS group were significantly lower ((0.39±0.03)Hz, (0.20±0.02)Hz, (0.07±0.02)Hz, both P<0.01; (9.98±0.31)pA, (7.74±0.21)pA, 6.36±0.13)pA, both P<0.01). Compared with CUMS group, the frequency and amplitude of mEPSC in SD+ CUMS group were lower (both P<0.01). Conclusion:Adolescent sleep deprivation aggravates depressive behavior and hippocampus synaptic plasticity impairment in adult CUMS model mice.

Objective:To investigate the value of left ventricular opacification (LVO) for measuring left ventricular (LV) remodeling parameters in ST-elevation myocardial infarction (STEMI) patients.Methods:Sixty-nine STEMI patients in Renmin Hospital of Wuhan University from April 2018 to December 2019 were enrolled. The apical four-chamber, three-chamber and two-chamber views of LV were collected with unenhanced and contrast-enhanced modes. According to the endocardium display in the unenhanced mode, all patients were divided into two groups: excellent image quality group ( n=23) and poor image quality group ( n=46). The endocardial segment display rate and mural thrombus diagnosis rate were compared between the two groups, and the improvement of LV overall image quality and LV apex display were evaluated in the poor image quality group.LV end diastolic volume (LVEDV), LV end systolic volume (LVESV), LV ejection fraction (LVEF) and LV global longitudinal strain (GLS) were measured with unenhanced and contrast-enhanced modes, respectively. The differences and repeatability of LV remodeling measurements of LVEDV, LVESV, LVEF and GLS in each group were compared with unenhanced and contrast-enhanced modes, and the feasibility and accuracy of GLS in contrast-enhanced mode were evaluated. Results:①Regardless of the image quality in the unenhanced mode, the display rate of endocardial segment in the contrast-enhanced mode was higher than that in the unenhanced mode (all P<0.05). ②For the poor image quality group, the overall image quality of LV and the display of LV apex were significantly improved in the contrast-enhanced mode (all P<0.05). ③For the poor image quality group, LVESV in contrast-enhanced mode was higher, while LVEF and GLS were lower than those in the unenhanced mode (all P<0.05). ④The correlation between GLS measured in contrast-enhanced and unenhanced mode was 0.912, and most of the measurements in the two modes were within the consistency threshold. For the poor image quality group, compared with GLS measured in the unenhanced mode, the correlation between GLS and LVEF measured in the contrast-enhanced mode was higher (0.731 vs 0.709). ⑤For the excellent image quality group, the interclass correlation coefficients (ICC) of most parameters were increased slightly in the contrast-enhanced mode, especially among interobservers. For the poor image quality group, the intra- and inter-observers′ ICC of LV remodeling mearsurements were increased significantly in the contrast-enhanced mode. Conclusions:LVO can more clearly display the LV structure of STEMI patients and obtain more repeatable LV remodeling measurements such as LVEDV, LVESV, LVEF and GLS, especially for patients with poor image quality.

Objective:To compare the efficacy of haplotype hematopoietic stem cell transplantation (HIDT) and sibling matched hematopoietic stem cell transplantation (MSDT) in the treatment of complete remission (CR) acute T-lymphoblastic leukemia (T-ALL) .Methods:We retrospectively analyzed the clinical characteristics and outcomes of 98 patients who underwent HSCT in Hebei Yanda Ludaopei hospital with HID ( n=81) or ISD ( n=17) between May 2012 and May 2016. Results:The incidence of grades 2-4 and 3-4 acute-versus-host disease 100 days after HSCT were 51.9% (95% Confidence interval [ CI] 42.0%-64.0%) vs 29.4% (95% CI 14.1%-61.4%) ( P=0.072) and 9.8% (95% CI 5.1%-19.1%) vs 11.8% (95% CI 3.2%-43.3%) ( P=1.000) for HIDT and MSDT. The 100-day cumulative incidences of CMV and EBV viremia were 53.1% (95% CI 43.3%-65.2%) vs 29.4% (95% CI 14.1%-61.4%) ( P=0.115) and 35.8% (95% CI 26.8%-47.9%) vs11.8% (95% CI 3.2%-43.3%) ( P=0.048) . The 5-year overall survival, leukemia-free survival, cumulative incidences of relapse, and no-relapse mortality were 60.5% (95% CI 5.4%-49.0%) vs 68.8% (95% CI 11.8%-40.0%) ( P=0.315) , 58.0% (95% CI 5.5%-46.5%) vs 68.8% (95% CI 11.8%-40.0%) ( P=0.258) , 16.1% (95% CI 9.8%-26.4%) vs 11.8% (95% CI 3.2%-43.3%) ( P=0.643) , 25.9% (95% CI 17.9%-37.5%) vs 19.4% (95% CI 6.9%-54.4%) ( P=0.386) for HIDT and MSDT, respectively. Conclusion:HID could be a valid alternative donor for patients with T-ALL in CR lacking an identical donor.

Objective:To study the clinical efficacy of chimeric antigen receptor T-cell (CART) treatment followed by a second allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with B-cell acute lymphoblastic leukemia (ALL) who relapsed following the first HSCT.Methods:Retrospective analysis of the clinical characteristics and prognosis of 41 patients with B-cell ALL who received a second allo-HSCT from October 2015 to June 2020 in Hebei Yanda Lu Daopei Hospital. After the first HSCT, all patients received CD19-CART, or CD22-CART treatment following a relapse of bone marrow morphology or extramedullary leukemia.Results:A total of 41 patients (male, 21; female, 20) were included in this study. The median age at the second HSCT was 16 (3-46) years. There were 31 cases of bone marrow recurrence (75.6%) , 5 cases of extramedullary recurrence (12.2%) , and 5 cases of bone marrow and extramedullary recurrences (12.2%) . After relapse, 35 patients (85.4%) received CD19-CART treatment, 2 patients received CD22-CART treatment (4.9%) , and 4 patients received CD19-CART and CD22-CART treatments (9.8%) . The expected 3-year overall survival (OS) , leukemia-free survival, cumulative relapse incidence, and non-relapse mortality (NRM) of patients after the second HSCT were 48.9% (95% CI 23.0%-70.6%) , 41.8% (95% CI 17.3%-64.9%) , 8.8% (95% CI 2.9%-26.4%) , and 51.1% (95% CI 31.2%-83.6%) , respectively. The 1-year OS of patients who relapsed ≤6 months and >6 months after the first HSCT were 45.0% (95% CI 12.7%-73.5%) and 75.0% (95% CI 51.4% -88.8%) ( P=0.017) , respectively. Conclusion:CART bridging in the second HSCT enables some B-cell ALL patients who relapsed after the first HSCT to achieve long-term survival. However, because of the high NRM, further modifications could help improve the outcome.

Objective: To investigate the influences of cardiovascular risk factors on left ventricular wall motion function in patients treated with epirubicin chemotherapy by layer-specific two-dimensional speckle tracking imaging (2D-STI). Methods: Sixty-four female patients with breast cancer treated with epirubicin and 36 controls from June 2018 to March 2019 in Renmin Hospital of Wuhan University were included. According to the numbers of cardiovascular risk factors, the patients were divided into group A (without cardiovascular risk factors, 31 cases), group B (single cardiovascular risk factor, 20 cases), and group C (multiple cardiovascular risk factors, 13 cases). All patients underwent echocardiography before and after epirubicin respectively. Global longitudinal strain, circumferential strain, radial strain (GLS, GCS, GRS), endocardial and epicardial layers of GLS and GCS (endoGLS, epiGLS, endoGCS, epiGCS) were obtained by EchoPAC software analysis. The differences of GLS, EndoGLS, EpiGLS, GCS, EndoGCS, EpiGCS and GRS before and after chemotheraphy were calculated as ΔGLS, ΔEndoGLS, ΔEpiGLS, ΔGCS, ΔEndoGCS, ΔEpiGCS and ΔGRS. Results: Compared with before chemotherapy, GLS, EndoGLS, EpiGLS, GCS, EndoGCS, EpiGCS and GRS were significantly reduced in group A, B and C after chemotherapy (all P<0.05). ΔEndoGLS and ΔEndoGCS showed an increasing trend in groups A, B and C, with statistical significance (all P<0.05). Correlation analysis showed that after chemotherapy with epirubicin, the numbers of cardiovascular risk factors were significantly correlated with strain parameters, and the correlation coefficient of EndoGLS was relatively higher (r=-0.582, P<0.001). Conclusions Layer-specific imaging can reliably detect the influences of cardiovascular risk factors on the left ventricular wall motion function in breast cancer patients treated with epirubicin. Parameters reflecting the endocardial longitudinal systolic function are sensitive indicators for the early detectin of myocardial damage and toxicity by epirubicin in patients with multiple cardiovascular risk factors.

Objective:To study the clinical results and prognostic factors for allo-HSCT of Philadelphia chromosome-positive (Ph +) acute lymphoblastic leukemia (ALL) in complete remission (CR) in the era of tyrosine kinase inhibitors (TKI) . Methods:We performed a retrospective analysis of the clinical characteristics of 116 patients with Ph +ALL who underwent allo-HSCT while in CR. Results:The study population included 72 men and 44 women. The median patient age was 20 years (4-64 years) . The patients received sibling-identical donor ( n=21) , haplo ( n=77) , and unrelated donor ( n=18) HSCT. The overall survival (OS) rate at 5 years was 73.2% (95% CI 63.8% -80.5% ) . In particular, the 5-year OS can reach 87.5% when the time from diagnosis to transplant is <180 days. The 5-years DFS was 61.4% (95% CI 51.8% -69.7% ) , the 5-year molecular and morphology cumulative relapse incidence was 18.5% (95% CI 12.6% -27.3% ) , and the 5-year TRM was 19.9% (95% CI 13.8% -28.7% ) . A multivariate analysis showed that an age range of 15-39 years ( HR=2.730, P=0.044) , time from diagnosis to HSCT ≥ 180 days ( HR=4.534, P=0.010) , and Ⅲ-Ⅳgrade aGVHD ( HR=7.558, P=0.000) were significantly associated with an inferior overall survival. Limited cGVHD subgroup had better OS ( HR=0.300, P=0.034) . Sex, WBC count at diagnosis, type of BCR-ABL fusion genes, somatic gene mutations, CR 1 or >CR 1, MRD negative or positive, conditioning regimen based on TBI or Bu, conditioning intensity, donor source, GVHD prophylactic proposal using cyclosporine or tacrolimus, presence/absence of CMV viremia, and presence/absence of EBV viremia were not significantly different in terms of the OS and DFS. Conclusion:Factors influencing the overall survival of Ph + ALL patients who underwent allo-HSCT in CR in the TKI era include age, time form diagnosis to HSCT, and aGVHD severity.
