Objective:To investigate the correlation between non-Hodgkin lymphoma (NHL) and chronic hepatitis B virus (HBV) infection by using the method of two-sample bidirectional Mendelian randomization (MR) analysis.Methods:Genetic variation data for NHL came from the Finnish database (FinnGen) Consortium 2021 public genome-wide association study (GWAS) dataset including 1 088 patients with NHL and 299 952 control subjects. The GWAS dataset for chronic HBV infection was derived from GWAS analysis published in 2021, including 145 NHL patients and 351 740 control subjects. NHL was used as an exposure factor, single nucleotide polymorphism (SNP) significantly associated with NHL was used as an instrumental variable (IV), chronic HBV infection was used as an outcome variable. The two-sample MR analysis was performed by using inverse-variance weighted (IVW) method. Chronic HBV infection was taken as an exposure factor, SNP significantly associated with chronic HBV infection was taken as IV, and NHL was taken as outcome variable, and then reverse two-sample MR analysis was performed. The IVW method used the inverse variance of each IV as the weight to fit, and the ratio method was used to measure SNP one by one and make weighted regression analysis, so as to obtain the overall estimate. MR-Egger regression and the weighted median (WME) method were also used to supplement the IVW method. In sensitivity analysis, leave-one-out sensitivity analysis was used to evaluate the impact of a single SNP. Cochran Q test was used to analyze the heterogeneity of the selected IV. MR-Egger regression was used to measure the average horizontal pleiotropy of IV, and the P-value of directivity was calculated. The MR-pleiotropy residual sum and outlier (MR-PRESSO) Global Test was used to exclude possible horizontal pleiotropic outliers and reduce bias. Results:In the leave-one-out sensitivity analysis, SNP with significant effects on causal associations was excluded. In forward MR analysis, IVs were 10 SNPs associated with NHL; the IVW method indicated that there was no causal association between NHL and chronic HBV infection ( OR = 0.979, 95% CI: 0.925-1.036, P = 0.465). MR-Egger regression ( OR = 0.992, 95% CI: 0.926-1.062, P = 0.825) and WME method ( OR = 0.992, 95% CI: 0.934-1.055, P = 0.805) were used as supplementary methods to obtain the consistent results. In sensitivity analysis, Cochran Q test showed no heterogeneity among IVs (IVW method: P = 0.271, MR-Egger regression: P = 0.239). Horizontal pleiotropy was not found in the MR-Egger regression (intercept was -0.01, P = 0.778) and the MR-PRESSO Global Test ( P > 0.05), suggesting robust results. In the reverse MR analysis, IVs were 8 SNPs associated with NHL; the IVW method ( OR = 1.117, 95% CI: 0.942-1.324, P = 0.202) also found no significant causal relationship between chronic HBV infection and NHL; MR-Egger regression ( OR = 0.777, 95% CI: 0.450-1.343, P = 0.401) and WME method ( OR = 1.120, 95% CI: 0.887-1.415, P = 0.351) also showed similar risk estimates. Sensitivity analysis also suggested the consistency and reliability of the results. Cochran Q test showed no heterogeneity among IVs (IVW method: P = 0.775, MR-Egger regression: P = 0.903). Horizontal pleiotropy was not found by MR-Egger regression (intercept was 0.102, P = 0.548) and MR-PRESSO Global Test ( P > 0.05). Conclusions:MR analysis suggests no causal relationship between NHL and chronic HBV infection.

Objective:To explore the association between childhood trauma and prefrontal cortex functional networks in early adulthood using functional near-infrared spectroscopy(fNIRS).Methods:Twenty-eight individu-als with childhood trauma comprised the trauma group,while 32 without trauma formed the control group.The Childhood Trauma Questionnaire(CTQ)assessed abuse and neglect,the Ruminative Responses Scale(RRS)meas-ured repetitive thinking about negative events,and the Iowa Gambling Task(IGT)evaluated decision-making tend-encies.fNIRS data collected during the IGT were used to calculate degree centrality(DC),betweenness centrality(BC),and local efficiency(LE)in prefrontal networks.Mediation analysis explored relationships among childhood trauma,brain function(DC,BC,LE),and ruminative thinking.Results:Compared to controls,the trauma group had decreased DC in bilateral dorsolateral prefrontal cortices,increased DC,BC,and LE in the right inferior frontal gy-rus,and elevated LE in the bilateral frontal poles.BC and LE in the right inferior frontal gyrus partially mediated the relationship between CTQ sexual abuse and RRS scores(48.57％and 41.43％,respectively).Conclusion:Child-hood trauma is significantly associated with changes in prefrontal network properties in early adulthood.Sexual a-buse,in particular,may influence emotional regulation and cognitive functions by altering the network attributes of the right inferior frontal gyrus.

OBJECTIVE To compare the cost-utility of eight programmed death 1(PD-1)/programmed cell death-ligand 1(PD-L1) inhibitor combination regimens for first-line treatment of advanced non-small cell lung cancer(NSCLC) from the perspective of Chinese healthcare system. METHODS Relevant data were derived from a published network meta-analysis and randomized controlled trails, a three-state Markov model was established to analyze the cost-utility of eight immunotherapy combinations. The robustness of results were validated through sensitivity analyses and a series of scenario analyses was also conducted. RESULTS The incremental cost-utility ratio(ICUR) of the sintilizumab plus chemotherapy group and the tislelizumab plus chemotherapy group were ￥125143.88/quality adjusted life year(QALY) and ￥189609.64/QALY, respectively, which were less than the willingness-to-pay(WTP) threshold of ￥257094/QALY, and all the ICURs of other PD-1/PD-L1 inhibitor combination regimens exceeded the WTP threshold and were not economical. Scenario analyses found that even if the medical insurance reimbursement ratio reached 80%, the different combinations of pembrolizumab, nivolumab and atezolizumab were not economical. CONCLUSION Compared with other PD-1/PD-L1 inhibitor combination regimens, sintilizumab plus chemotherapy and tislelizumab plus chemotherapy have cost-utility advantages in the first-line treatment of advanced NSCLC, which can provide a certain reference for selecting a reasonable treatment plan for NSCLC patients.

Objective:To evaluate the therapeutic effect of glycyrrhetinic acid on cough variant asthma (CVA) mice based on molecular docking technique; To explore the possibility of its treatment for cough variant asthma.Methods:The software of Autodock Vina was used for molecular docking. The mice were divided into control group, model group, prednisone acetate group, glycyrrhetinic acid high-, medium-, and low-dosage groups according to the random number table method, with 8 mice in each group. Except for the blank control group, all other groups were induced by egg protein to establish cough variant asthma models. Glycyrrhetinic acid high-, medium-, and low-dosage groups were orally administered glycyrrhetinic acid suspension at 20, 10, and 5 mg/kg, while the prednisone acetate group was orally administered prednisone acetate at 5 mg/kg. The blank control group and model group were orally administered equal volumes of physiological saline, once per day for 14 consecutive days. The animal asthma behavior was observed after drug administration. The secretion of bronchial mucus in lung tissue were observed by AB-PAS staining and the index of spleen were recorded. The protein expressions of Gata3, IL-4 and IL-13 in the spleen tissue were determined by Western blot.Results:Molecular docking results showed that glycyrrhetinic acid had good binding ability to Th2-related factors Gata3, IL-4 and IL-13. Results of animal experiment showed that compared with the model group, the mucus secretion decreased in glycyrrhetinic acid groups, the index of the spleen of mice obviously decreased, protein expression levels of IL-4 and IL-13 in the spleen tissue of mice in glycyrrhetinic acid high-, medium-, and low-dosage groups decreased ( P<0.05), and Gata3 in glycyrrhetinic acid medium- and low-dosage groups decreased ( P<0.05). Conclusion:Glycyrrhetinic acid can correct the shift of Th2 in the immune system of cough variant asthma mice and has a certain therapeutic effect.

Objective:To investigate the incidence of venous thromboembolism (VTE) in patients with esophageal cancer (EC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 8 458 EC patients who were admitted to Sichuan Cancer Hospital from January 2017 to December 2021 were collected. There were 6 923 males and 1 535 females, aged (64±9)years. There were 3 187 patients undergoing surgical treatment, and 5 271 cases undergoing non-surgical treatment. Observation indicators: (1) incidence of VTE in EC patients; (2) treatment and outcomes of patients with VTE. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the nonparameter rank sum test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the nonparameter rank sum test. Results:(1) Incidence of VTE in EC patients. Of 8 458 EC patients, 175 cases developed VTE, with an incidence rate of 2.069%(175/8 458). Among 175 VTE patients, there were 164 cases of deep venous thrombosis (DVT), 4 cases of pulmonary embolism (PE), 7 cases of DVT and PE. There were 59 surgical patients and 116 non-surgical patients. There was no significant difference in thrombus type between surgical and non-surgical EC patients with VTE ( χ2=1.95, P>0.05). Of 3 187 surgical patients, the incidence of VTE was 1.851%(59/3 187), including an incidence of 0.157%(5/3 187) of PE. PE accounted for 8.475%(5/59) of surgical patients with VTE.

Objective     To investigate the risk factors for postoperative complications Clavien-Dindo classification≥grade Ⅱ after lung cancer surgery. Methods     The patients who underwent lung cancer surgery in a multicenter observational study from November 2017 to January 2020 were included. The Clavien-Dindo classification of postoperative complications was analyzed. Logistic regression was used to identify the risk factors for complications≥ gradeⅡ. Results     A total of 388 patients were enrolled, including 203 males and 185 females with a mean age of 56.14±10.36 years. The incidence of postoperative complications was 25.52% (99/388) after lung cancer surgery and the incidence of complications≥gradeⅡ was 20.10% (78/388). The five most common postoperative complications were pneumonia (6.96%), prolonged pulmonary air leak (>7 days, 5.67%), incision dehiscence (4.64%), arrhythmia (3.87%), and postoperative pleural effusion (3.35%). Multivariate analysis showed that open surgery [reference: uniportal thoracoscopic surgery, OR=2.18, 95%CI (1.01, 4.70), P=0.047], extended resection [reference: sublobar resection, OR=2.86, 95%CI (1.11, 7.19), P=0.030; reference: lobectomy, OR=2.20, 95%CI (1.10, 4.40), P=0.026] and operative time≥3 h [OR=2.07, 95%CI (1.12, 3.85), P=0.021] were independent risk factors for postoperative complications≥gradeⅡ after lung cancer surgery. Conclusion     Surgical approach, extent of resection and operative time are independent influencing factors for postoperative complications≥gradeⅡ after lung cancer surgery.

OBJECTIVE：To explore the mode of pharmaceutical care for oral medication of tumor patients with dysphagia by clinical pharmacists ，so as to promote clinical rational and safe drug use. METHODS ：Based on typical cases ，the problems existing in the oral medication of tumor patients with dysphagia were analyzed ，and the medication guidance and pharmaceutical care given by clinical pharmacists were expounded. RESULTS ：Clinical pharmacists found that tumor patients with dysphagia had some problems during oral medication ，such as improper administration position ，tube feeding of slow-controlled release preparations after opening the capsule ，limited administration route ，biting cytotoxic drugs ，unknown solubility of targeted drugs ，interaction of multiple drugs. In view of the above problems ，clinical pharmacists assisted physicians and nursing staff to provide pharmaceutical care to patients in combination with the patient ’s disease characteristics ，pharmacy，pharmacokinetics，pharmacodynamics，drug solubility，drug interaction and other factors ，such as skillfully using appropriate drug delivery location and mode ，using local drug delivery mode ，selecting appropriate dosage form based on pharmaceutical knowledge （the characteristics of new dosage form ）， guiding patients to use drugs correctly by being familiar with the characteristics of cytotoxic drugs and targeted drugs ，paying attention to potential drug interactions and guiding nurses to use drugs correctly. The situation of improper medication was improved. CONCLUSIONS ：Clinical pharmacists should participate in clinical therapy actively ，and make appropriate interventions with professional knowledge of pharmacy so as to promote the correct use of oral medication for tumor patients with dysphagia.

Objective:This study analyzes the expression level of miR-1180-3p and constructs the regulatory network of relevant ceRNA by integrating the DNA methylation and gene expression profile of hepatocellular carcinoma from the Cancer Genome Atlas (TCGA).Methods:Firstly, the expression level of miR-1180-3p in hepatocellular carcinoma and adjacent tissues was analyzed by TCGA database, and the differential expression of lncrna and mRNA was screened. Secondly, the LncBase database and the TargetScan database were used to predict the relationship between miR-1180-3p and lncRNA and mRNA, and the DNA methylation-mediated lncRNA was screened by the DNA methylation profile of lncRNA. Finally, Cytoscape software was used to construct miR-1180-3p relevant ceRNA network, and WebGestalt website was used to perform GO and KEGG analysis of related mRNA in ceRNA.Results:Compared with patients with low expression of miR-1180-3p (mean overall survival duration, 5.69 ± 0.35 years), patients with high expression of miR-1180-3p had shorter overall survival time (mean overall survival duration, 3.99 ± 0.47 years), indicating that the high expression of miR-1180-3p was hepatocellular carcinoma risk factor affecting the prognosis ( HR = 1.28, 95% CI = 1.1 ~ 1.5, P < 0.01). A miR-1180-3p related ceRNA regulatory network was constructed in this study, which contained 2 lncRNAs (F11-AS1 and LINC01511) and 37 mRNAs. Conclusion:This study has successfully constructed miR-1180-3p relevant ceRNA regulatory network, and DNA methylation-mediated F11-AS1 and F11-AS1/miR-1180-3p/C11of54 ceRNA regulatory axis has played an important role in the occurrence and development of hepatocellular carcinoma.

Immune checkpoint inhibitor (ICI) has been emerged as a major breakthrough in tumor immunotherapy, but its unique mechanism of action has also led to a number of immune-related adverse events (irAE). Type 1 diabetes mellitus (T1DM) is one of the rarest irAEs. This paper reports a case of advanced malignant liver tumor-induced T1DM who received second-line anti-PD-1 therapy and showed initial symptoms of hyperosmolar coma and hyperglycemia. In addition, the relevant literature at home and abroad was collected and reviewed, and the clinical characteristics of T1DM induced by anti-PD-1 therapy were summarized with a view to achieve early detection, diagnosis and treatment.
