Objective To evaluation the efficacy of ketamine on the expression of adhension molecular CR3and intracellular cAMP, cGMP in neutrephils in patients associated with cardiopulmonary bypass (CPB), as well as the cardiovascular function of the CPB patients. Method Sixty patients operated on with prosthetic valve replace-rnent under CPB were randomly divided into 4 groups: placebo, ketamine 0.1 mg/kg ( ketamine Ⅰ) ,ketamine 0.5 mg/kg ( ketamine Ⅱ) ,ketamine 1 mg/kg( ketamine Ⅲ). Each group included 15 eases. Venous blood sam-pies were obtained during anesthesia induction (T1), 10 min before CPB (T2), end of CPB (T3) and 24 hoursafter operation (T4). The expression of CR3 was measured by Flow cytometry and the concentration of cAMP/cGMP by HPLC. Results Ketamine with various dosages decreased the expression of CR3 at the T3 and T4 inpatients of ketamine groups compared with patients of placebo group (P<0.05). The dosages of ketamine Ⅱgroup and ketamine Ⅲ group had more significant effect than that of ketamine Ⅰ group. The dosages of ketamineⅡ and ketamine Ⅲ group increased the intracellular cAMP at the T3 and T4 compared with ketamine Ⅰ groupand placebo (p<0.05), respectively. However,cGMP was lower in ketamine Ⅱ and ketamine Ⅲ group thanthat in ketamine Ⅰ group and placebo (P<0.05) at the T3.Morever,the mean arterial blood pressure was higherin ketamine Ⅱ and ketamine Ⅲ group at T4. Only the patients of ketamine Ⅲ group required less inotropic drugsafter operation. Conclusions Ketamine can reduce the expression of adhhension molecular CB3 and intracellularcAMP, cGMP in neutrophils from patients associated with CPB.

AIM: To observe the effects of Egr-1 gene knockout on the expression of inflammatory-related factors in pancreatic tissue in a mouse acute pancreatitis model.METHODS: The experimental pancreatitis was induced by high-dose of cearulein in wildtype mice and Egr-1 knockout mice.The pancreatitis indexes,such as serum amylase,pancreata edema,and myeloperoxidase(MPO) levels in pancreata and lungs were recorded.The mRNA levels of tissue factor(TF),plasminogen activator inhibitor(PAI-1),monocyte chemoattractant protein(MCP-1),Gro-1,IL-6 and ICAM-1 were measured by quantitative PCR.RESULTS: Contrary to wildtype mice,typical pancreatitis was not induced by high-dose cearulein in the Egr-1 knockout mice,not only markedly reduced edema in pancreata and lungs,but decreased MPO levels in lungs as well were found.Furthermore,the mRNA of TF,PAI,MCAP,ICAM-1 and IL-6 in pancreata were significantly decreased in Egr-1 knockout mice.CONCLUSION: The severity of pancreatitis and lung damage is ameliorated in Egr-1 knockout mice stimulated by high-dosage of cearulein,which was probably mediated by decreasing expression of inflammatory-related factors in pancreata,such as TF,PAI,MCP-1,ICAM-1 and IL-6.

Inhibition of human cytochrome P450 (CYP) can lead to drug-drug interactions, resulting in serious adverse reactions.It is therefore crucial to accurately predict the inhibitory power of a given compound against a particular CYP isoform.This study compared 11 machine learning methods and 2 deep learning models based on different molecular representations.The experimental results showed that the CatBoost machine learning model based on RDKit_2d+Morgan outperformed other models in terms of accuracy and Mathews coefficient, and even outperformed previously published models.Moreover, the experimental results also showed that the CatBoost model not only had superior performance, but also consumed less computational resources.Finally, this study combined the top 3 performing models as co_model, which slightly outperformed the CatBoost model alone in terms of performance.

Objective: To propose reasonable suggestions to promote the standardization of clinical studies by reviewing the systematic reviews and meta-analyses of acupuncture-moxibustion treatment of essential hypertension (EH). Methods: Computer retrieval was conducted through Excerpta Medica Database (EMBASE), PubMed, China National Knowledge Infrastructure (CNKI), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), and Wanfang Academic Journal Full-text Database (Wanfang) to collect systematic reviews and meta-analyses relevant to treating EH with acupuncture-moxibustion therapy. The time range was from the database's inception till July, 2020. The studies were screened based on the inclusion and exclusion criteria and then data-extracted. The study's quality and evidence ratings were performed by referring to the preferred reporting items for systematic review and meta-analysis (PRISMA), a measurement tool to assess systematic reviews 2 (AMSTAR 2), and the grading of recommendations, assessment, development, and evaluation (GRADE). Results: A total of 14 studies, 10 in Chinese and 4 in English, published between 2012 and 2019, were included, involving 70 outcome measures. The methodological quality was rated as critically low, the reporting was relatively complete or had certain flaws, and the evidence strength was rated as low or very low. Conclusion: Regarding the acupuncture-moxibustion treatment of EH, the methodological quality and outcome measure evidence of existing systematic reviews and meta-analyses are relatively low, and the reporting quality also expects further improvements.

Objective:To explore the role of mindfulness and negative cognitive bias between behavioral inhibition system and social anxiety among college students.Methods:From October 12th to November 8th of 2012, a total of 747 college students from a university in Tianjin were sampled and assessed using the behavioral inhibition system scale (BIS), the mindful attention awareness scale (MAAS), the negative cognitive processing bias questionnaire (NCPBQ), and the social avoidance and distress scale (SAD). Descriptive statistics, correlation analysis, and tests for mediating effects were performed by SPSS 20.0 and Mplus 8.0.Results:The scores of behavioral inhibition system, social anxiety, mindfulness and negative cognitive bias were (15.3±2.4), (12.7±7.2), (3.4±0.8) and (45.6±11.5), respectively. The scores of BIS, NCPBQ, and SAD were positively correlated with each other ( r=0.27-0.49, all P<0.001). The scores of MAAS were negatively correlated with the scores of BIS, NCBPQ, and SAD ( r=-0.33--0.28, all P<0.001). The behavioral inhibition system exerted its influence on social anxiety through three pathways. The mediating effect size of mindfulness was 0.04, accounting for 16.0% of the total effect. The mediating effect size of negative cognitive bias was 0.17, accounting for 68.0% of the total effect. And the chain mediating effect size of mindfulness and negative cognitive bias was 0.04, accounting for 16.0% of the total effect. Conclusion:The effects of behavioral inhibition system on social anxiety in college students are individually mediated by mindfulness and negative cognitive biases, as well as their chain mediating effects.

Objective:To explore the relationship between intolerance of uncertainty and internet addiction among college students, as well as the mediating roles of negative cognitive bias and difficulties in emotion regulation.Methods:In September 2022, 1 762 college students were assessed with intolerance uncertainty scale, negative cognitive process bias questionnaire, difficulties in emotion regulation scale and internet addiction test. SPSS 24.0 software was used for descriptive statistics and correlation analysis. AMOS 23.0 was used to construct a multiple mediation model, and Bootstrap method was used for mediation effects testing.Results:(1) The score of intolerance of uncertainty was 34.00 (28.00, 40.00), the score of negative cognitive bias was 42.00 (34.00, 50.00), the score of difficulties in emotion regulation was 26.00 (20.00, 32.00), and the score of internet addiction was 36.00 (28.00, 46.00). (2)The Spearman correlation analysis showed that intolerance of uncertainty, negative cognitive bias, difficulties in emotion regulation, and internet addiction were significantly positively correlated with each other ( r=0.343-0.626, P<0.01). (3) The results of the path analysis indicated that the direct effect of intolerance of uncentainty on internet addiction was not significant, and the total indirect effect was 0.402(95% CI=0.354-0.451).The indirect effect of negative cognitive bias was 0.253(95% CI=0.200-0.305), accounted for 62.94%(0.253/0.402) of the total indirect effect.The indirect effect of difficulties in emotion regulation was 0.052 (95% CI=0.033-0.076), accounted for 12.93%(0.052/0.402) of the total indirect effect.And the chain mediating effect of negative cognitive bias and difficulties in emotion regulation was 0.097(95% CI=0.068-0.131), accounted for 24.13%(0.097/0.402) of the total indirect effect. Conclusion:Intolerance of uncertainty is significantly positively correlated with internet addiction, and its effects on internet addiction are individually mediated by negative cognitive bias and difficulties in emotion regulation, as well as their chain mediating effects.

Objective To explore the efficacy of hematopoietic stem cell transplantation (HSCT) for 5 patients with Ph-like acute lymphoblastic leukemia (ALL).Methods Fluorescent in situ hybridization (FISH) was performed for detecting the rearrangement of susceptibility genes.Combined therapy of chemotherapy and ruxolitinib were applied,followed by HSCT.Those failing to achieve complete remission (CR) received an infusion of chimeric antigen T-cells (CAR-T),followed by HSCT once CR was achieved.Four patients accept allogenic HSCT while another auto HSCT.Results Three of them achieved CR after chemotherapy and ruxolitinib.The remaining 2 patients got CR after CAR-T.Four patients remained in CR after HSCT.Early relapse occurred in 1 patient after HSCT.Conclusions Combined therapy of chemotherapy,ruxolitinib and CAR-T are necessary for Phlike ALL patients.HSCT after an initial CR improve patient prognosis.

Objective To improve the understanding of the diagnosis and treatment of Philadelphia (Ph) chromosome-like acute lymphoblastic leukemia (ALL) with EBF1-PDGFRB-positive. Methods One case of Ph-like ALL with EBF1-PDGFRB-positive from the First Affiliated Hospital of Soochow University was reported. Whole exome sequencing was applied to detect the EBF1-PDGFRB fusion gene. Fluorescence in situ hybridization (FISH) was used to detect minimal residual disease. Comprehensive treatments including chemotherapy, imatinib and chimeric antigen T-cell (CAR-T) therapy were utilized. Results EBF1-PDGFRB fusion gene in the bone marrow samples was detected by using whole exome sequencing at early diagnosis. The rearrangement of PDGFRB showed continuous negative after comprehensive therapy. The patient achieved continuous molecular remission for 22 months. Conclusions The comprehensive treatments include combined chemotherapy, CAR-T therapy and tyrosine kinase inhibitor can promote the continuous of major molecular remission for EBF1-PDGFRB-positive Ph-like ALL patients.

Objective:To observe the efficacy and safety of decitabine combined with chemotherapy in treatment of relapsed/refractory T lymphoblastic lymphoma/leukemia (T-LBL/ALL) with TP53 mutation.Methods:The clinical data of a T-LBL/ALL patient with TP53 mutation who had recurrence after allogeneic hematopoietic stem cell transplantation (allo-HSCT) treated with decitabine combined with chemotherapy in the First Affiliated Hospital of Soochow University in June 2018 were retrospectively analyzed and the relevant literature was reviewed.Results:The patient, a 42-year-old male, diagnosed as T-LBL/ALL with TP53 mutation by comprehensive examination underwent sibling-matched donor allo-HSCT after a second complete remission. The patient relapsed 8 months later and was treated with decitabine combined with CLAG regimen to achieve complete remission again. And then, he had leukemia-free survival until now through maintenance treatment with decitabine.Conclusion:Decitabine combined with chemotherapy may be a safe and effective treatment option for relapsed T-LBL/ALL patients with TP53 mutation after allo-HSCT.

Objective:To analyze the factors affecting delayed chemotherapy in children with Burkitt lymphoma (BL) and their influence on prognosis.Methods:Retrospective cohort study. Clinical data of 591 children aged ≤18 years with BL from May 2017 to December 2022 in China Net Childhood Lymphoma (CNCL) was collected. The patients were treated according to the protocol CNCL-BL-2017. According to the clinical characteristics, therapeutic regimen was divided into group A, group B and group C .Based on whether the total chemotherapy time was delayed, patients were divided into two groups: the delayed chemotherapy group and the non-delayed chemotherapy group. Based on the total delayed time of chemotherapy, patients in group C were divided into non-delayed chemotherapy group, 1-7 days delayed group and more than 7 days delayed group. Relationships between delayed chemotherapy and gender, age, tumor lysis syndrome before chemotherapy, bone marrow involvement, disease group (B/C group), serum lactate dehydrogenase (LDH) > 4 times than normal, grade Ⅲ-Ⅳ myelosuppression after chemotherapy, minimal residual disease in the interim assessment, and severe infection (including severe pneumonia, sepsis, meningitis, chickenpox, etc.) were analyzed. Logistic analysis was used to identify the relevant factors. Kaplan-Meier method was used to analyze the patients' survival information. Log-Rank was used for comparison between groups.Results:Among 591 patients, 504 were males and 87 were females, the follow-up time was 34.8 (18.6,50.1) months. The 3-year overall survival (OS) rate was (92.5±1.1)%,and the 3-year event-free survival (EFS) rate was (90.5±1.2)%. Seventy-three (12.4%) patients were in delayed chemotherapy group and 518 (87.6%) patients were in non-delayed chemotherapy group. The reasons for chemotherapy delay included 72 cases (98.6%) of severe infection, 65 cases (89.0%) of bone marrow suppression, 35 cases (47.9%) of organ dysfunction, 22 cases (30.1%) of tumor lysis syndrome,etc. There were 7 cases of chemotherapy delay in group B, which were seen in COPADM (vincristine+cyclophosphamide+prednisone+daunorubicin+methotrexate+intrathecal injection,4 cases) and CYM (methotrexate+cytarabine+intrathecal injection,3 cases) stages. There were 66 cases of chemotherapy delay in group C, which were common in COPADM (28 cases) and CYVE 1 (low dose cytarabine+high dose cytarabine+etoposide+methotrexate, 12 cases) stages. Multinomial Logistic regression analysis showed that the age over 10 years old ( OR=0.54,95% CI 0.30-0.93), tumor lysis syndrome before chemotherapy ( OR=0.48,95% CI 0.27-0.84) and grade Ⅲ-Ⅳ myelosuppression after chemotherapy ( OR=0.55,95% CI 0.33-0.91)were independent risk factors for chemotherapy delay.The 3-year OS rate and the 3-year EFS rate of children with Burkitt lymphoma in the delayed chemotherapy group were lower than those in the non-delayed chemotherapy group ((79.4±4.9)% vs. (94.2±1.1)%, (80.2±4.8)% vs. (92.0±1.2)%,both P<0.05). The 3-year OS rate of the group C with chemotherapy delay >7 days (42 cases) was lower than that of the group with chemotherapy delay of 1-7 days (22 cases) and the non-delay group (399 cases) ((76.7±6.9)% vs. (81.8±8.2)% vs. (92.7±1.3)%, P=0.002).The 3-year OS rate of the chemotherapy delay group (9 cases) in the COP (vincristine+cyclophosphamide+prednisone) phase was lower than that of the non-chemotherapy delay group (454 cases) ((66.7±15.7)% vs. (91.3±1.4)%, P=0.005). Similarly, the 3-year OS rate of the chemotherapy delay group (11 cases) in the COPADM1 phase was lower than that of the non-chemotherapy delay group (452 cases) ((63.6±14.5)% vs. (91.5±1.3)%, P=0.001). Conclusions:The delayed chemotherapy was related to the age over 10 years old, tumor lysis syndrome before chemotherapy and grade Ⅲ-Ⅳ myelosuppression after chemotherapy in pediatric BL. There is a significant relationship between delayed chemotherapy and prognosis of BL in children.
