To establish a simple and sensitive LC-MS/MS method for simultaneous determination of the concentration for L-tryptophan(L-Try)and L-kynurenine(L-Kyn)in rat plasma. The changesin the process of the liver tumors formation may provide a basis for the diagnosis of liver cancer. 3-Nitro-L-tyrosine(3-NT)were added as the internal standard for the determination of two active substances and the chromatographic analysis was performed on a RRHD Eclipse Plus C18 column(3. 0 mm×100 mm, 1. 8 μm). The mobile phase was composed of water and acetonitrile(containing 0. 1%formic acid)(90 ∶10)at a flow rate of 0. 25 mL/min, and the injection volume is 5 μL. Detection and quantification were performed by mass spectrometry in multiple reaction monitoring mode with m/z 205. 12→146. 10(L-Try), m/z 209. 09 →146. 10(L-Kyn), m/z 227. 09→181. 10(3-NT), respectively. The results show that thelinear ranges were 9. 670-9 670 ng/mL for L-Try, and 9. 973-9973 ng/mL for L-Kyn(r2≥0. 9990). The limit of quantitation were 9. 670 ng/mL for L-Try, and 9. 973 ng/mL for L-Kyn, respectively. The intra- and inter-day precisions were all less than15%; the recoveries ofthe two analytes were more than 81. 17% and severe matrix effect was not observed. The ratio of L-Try/L-Kyn determined by LC-MS/MS in rat plasma showed an overall downward trend, which could used effectively for the drug metabolism studies and researches on the action mechanism of medicine on liver cancer. A rapid, simple, sensitive and specific LC-MS/MS method has been successfully developed and could also be used effectively for the drug metabolism studies and researches on the action mechanism of medicine on liver cancer.

Objective:To analyze the clinical efficacy and prognostic factors of intracranial primary diffuse large B-cell lymphoma (DLBCL).Methods:Clinical data of 205 patients pathologically diagnosed with intracranial primary DLBCL at Sun Yat-sen University Cancer center from March 2001 to September 2020 were retrospectively analyzed. Among them, 101 patients were male and 104 female, the median age was 54 years old. Non-germinal center B cell (GCB) subtype accounted for 74.1%(126/170). A total of 177 patients received high-dose methotrexate (HD-MTX) and 91 patients received rituximab. After induction chemotherapy, 59 patients (30.4%) achieved complete response (CR), 112 patients (57.7%) achieved partial response (PR) or stable disease (SD). A total of 83 patients received consolidation or salvage radiotherapy, and only 14 patients received autologous stem cell transplantation (ASCT). The influence of pathological type, chemotherapy, rituximab treatment, radiotherapy and radiotherapy mode, ASCT and other factors on the overall survival (OS) and progression free survival (PFS) was evaluated. The survival rate was calculated by Kaplan-Meier method. Univariate prognostic analysis was performed by log-rank test. Multivariate prognostic analysis was conducted by COX model.Results:The median follow-up time was 34 months. The 5-year OS and PFS rates were 55.6% and 44.2%, respectively. GCB subtype, chemotherapy with HD-MTX, rituximab treatment, remission status after induction chemotherapy, and radiotherapy were favorable prognostic factors for OS or PFS, in which the last three were the independent prognostic factors. Consolidation radiotherapy in patients who obtained CR after induction chemotherapy did not significantly improve survival, while salvage radiotherapy in patients who achieved PR/SD after induction chemotherapy significantly improved both OS and PFS(both P<0.01). Consolidation radiotherapy showed no significant survival difference compared with consolidation ASCT. Conclusions:The non-GCB subtype of intracranial primary DLBCL is related to poor prognosis. The addition of rituximab to HD-MTX based induction chemotherapy can improve survival. Radiotherapy is still an important treatment for intracranial primary DLBCL, and there are limitations of ASCT in practical clinical application.

ObjectiveTo evaluate the efficacy and influencing factors of Biejiajianwan in the treatment of primary liver cancer based on real-world data of traditional Chinese medicine (TCM). MethodClinical diagnosis and treatment data of patients with primary liver cancer admitted to five Grade-A tertiary hospitals in Henan Province from January 2015 to December 2020 were collected from the medical electronic database. The patients treated with Biejiajianwan for ≥30 days were assigned to the exposure group and those without treatment with Biejiajianwan or treated with Biejiajianwan for <30 days to the non-exposure group. The propensity score matching model was used to balance confounding factors between the two groups according to the 1∶1 genetic matching method. Kaplan-Meier method was used for survival analysis and survival curve plotting. Log-rank was used to test the difference in survival rate between the two groups. Univariate analysis of Biejiajianwan in the treatment of primary liver cancer was performed by Log-rank test combined with the Kaplan-Meier method. The factors with statistical significance (P<0.05) were combined with unbalanced factors by the propensity score matching model, and at the same time, clinical common sense and relevant prognostic factors by literature search were considered, which were subjected to multivariate analysis by Cox proportional hazards regression model. ResultA total of 2 207 electronic cases were collected,including 174 cases in the exposure group (Biejiajianwan group) and 2 033 cases in the non-exposure group. After propensity score matching, there were 174 cases in the exposure group and 174 cases in the non-exposure group. The Kaplan-Meier method was used for survival analysis on the matched data, and the Log-rank test results showed that the survival rate of patients with primary liver cancer in the Biejiajianwan group was higher than that in the control group (χ2=12.193, P<0.01). Cox proportional hazards regression model analysis showed that the regression coefficient of Biejiajianwan was -0.916 4 with the hazard ratio (HR) [95% confidence interval (CI)]=0.4 (0.239 5-0.668 0), P<0.01, and the regression coefficient of radiofrequency ablation treatment was -0.976 5 with HR (95% CI)=0.376 6 (0.172 8-0.821 1, P<0.05). Fibrinogen (FIB) abnormal regression coefficient was 0.481 4 with HR (95% CI)=1.618 4(1.022 0-2.562 9),P<0.05. ConclusionBiejiajianwan can prolong the survival period of patients with primary liver cancer. Radiofrequency ablation is an independent protective factor for Biejiajianwan in the treatment of primary liver cancer,while abnormal FIB are independent risk factors for Biejiajianwan in the treatment of primary liver cancer.
