The 2024 World Conference on Lung Cancer (WCLC) and the European Society for Medical Oncology (ESMO) Annual Meeting, two of the most prestigious events in oncology, have concluded sequentially. As the most authoritative annual gatherings in lung cancer and the entire oncology field, the WCLC and ESMO conferences brought together top oncology experts and scientists from around the world to share, discuss, and publish the latest cutting-edge advancements in oncology. In both conferences, lung cancer immunotherapy remained a hot topic of considerable interest. This article aims to summarize and discuss the important research progress on perioperative immunotherapy for non-small cell lung cancer reported at the two conferences.

Objective:To investigate whether systemic immune inflammation index(SII)-C-reactive protein/albumin(CRP/Alb)can predict postoperative survival in non-small cell lung cancer(NSCLC)patients.Methods:A total of 262 patients with NSCLC who underwent surgery in Hebei Provincial People's Hospital from January 2017 to November 2020 were included.SII and CRP/Alb expressions in patients after surgery were analyzed by K-M survival curve analysis,Cox multivariate risk regression analysis and ROC curve analysis.Results:Patients with high SII expression(>961.78)and high CRP/Alb expression(>0.025)had worse outcomes than patients with low SII and CRP/Alb expressions,respectively(P<0.001).SII-CRP/Alb score(P=0.032),age≥60 years(P=0.038)and T stage T2～T3(P<0.001)were significantly associated with shorter overall survival.AUC of SII-CRP/Alb scores were larger than SII and CRP/Alb scores,respectively.Conclusion:SII-CRP/Alb score can effectively evaluate postoperative survival status of patients with NSCLC,and SII-CRP/Alb score are independent predictors of postoperative overall survival in NSCLC patients.

The biotransformation processes in the human body play a crucial role in maintaining the inter-nal environment's stability by converting exogenous compounds and endogenous metabolites into substances with increased polarity or water solubility.This alteration in toxicity or pharmacological effects facilitates their excretion from the body.Sulfation,an important type of phase Ⅱ biotransformation reaction,is primarily me-diated by members of the cytosolic sulfotransferases(also known as sulfotransferases,SULTs)superfamily.Recent studies have uncovered the significant roles of SULTs in drug metabolism,tumorigenesis,inflammato-ry responses,hormone regulation,and energy metabolism.This article provides a comprehensive review of the regulatory roles and molecular mechanisms of the SULTs superfamily members in carbohydrate and lipid me-tabolism,aiming to offer new insights into the mechanism research and drug development for disorders related to carbohydrate and lipid metabolism dysregulation.

Objective:To explore the protective effect and mechanism of irisin on liver injury and mitochondrial dysfunction of hepatocytes in mice with acute necrotizing pancreatitis (ANP).Methods:24 mice were randomly divided into the control group, the ANP group, the irisin group and the cilengitide group, with 6 mice in each group. The ANP group was prepared by intraperitoneal injection of 20% L-arginine. The irisin group was injected with 250 μg/kg of irisin intraperitoneally on the basis of the induction of ANP. The cilengitide group was injected with the integrin receptor αVβ3/5 inhibitor cilengitide at 20 mg/kg on the basis of the treatment of the irisin group. The control group was injected with 0.9% normal saline instead of L-arginine. Routine liver histopathological examination and scoring were performed; immunohistochemical staining was used to detect the level of neutrophil infiltration in liver tissue; the ultrastructure changes of mitochondria were observed under transmission electron microscopy; biochemistry was used to detect the ATP content in liver tissue to reflect the changes in mitochondrial function; the total antioxidant capacity of liver tissue was detected by the ferric reducing/antioxidant power (FRAP) method; the DHE fluorescence probe labeling method was used to detect the accumulation degree of oxygen free radicals in liver tissue.Results:The livers of the control group showed no obvious abnormalities. However, the ANP group, the irisin group and the cilengitide group all had liver tissue damage and infiltration of inflammatory cells in the mice. Compared with the ANP group, the liver pathological score, the number of neutrophil infiltration, and the DHE fluorescence staining density in the irisin group were significantly lower [(3.40±0.72) vs (7.26±1.01) points, (14.67±2.51) vs (33.33±3.51) cells, (16.33±5.03) vs (50.33±10.69) cells], while the above indicators in the cilengitide group were all increased [(7.06±1.55) points, (40.33±5.03) cells, (51.00±12.8) cells]; the ATP content [(296.04±64.6), (54.77±18.05), (109.50±56.61), (40.29±11.68) μmol/gprot], and the antioxidant capacity [(0.19±0.01), (0.10±0.01), (0.17±0.02), (0.11±0.01) mmol/g] in the control group, ANP group, irisin group and cilengitide group changed accordingly. The above differences were statistically significant (all P value <0.05). Transmission electron microscopy observation revealed that the abnormal mitophagy of liver cells in the irisin group restored to normal, while the mitophagy abnormality in the cilengitide group was exacerbated. Conclusions:Irisin could improve the disordered mitochondrial function and oxidative stress in liver cells by acting on integrin receptors αVβ3/5, thereby alleviating liver damage and inflammatory responses in ANP mice.

OBJECTIVE To establish the quality standard of Triadica cochinchinensis and to perform the acute toxicity study. METHODS Appearance properties, powder microscopic identification, and thin-layer chromatography(TLC) identification were researched. The specific chromatogram was established by HPLC. The content of cadmium(Cd), lead(Pb), arsenic(As), copper(Cu), and mercury(Hg) was determined by inductively coupled plasma-mass spectrometry(ICP-MS). Acute toxicity was studied by maximum dose. RESULTS The outer skin of herbs was dark brown, and the inner surface was light yellow brown and fibrous. Besides, crystal sheath fiber was common, and calcium oxalate clusters arranges in rows. In the TLC diagram of the test product, the fluorescent spots of the same color were displayed at the corresponding position of the control product(scopoletin, isofraxidin). Five common peaks were calibrated in the characteristic map and the three characteristic peaks(scopoletin, isofraxidin, dimethylfraxetin) were recognized. The content of the measured heavy metal elements was lower than the national limit standard. The linear correlation coefficient was R2 > 0.999. The precision, stability, repetitive RSD were < 10%. The average recovery rate of the added sample was 80%−120%, and the RSD was < 10%. The maximum dose of the acute toxicity test was 184.09 g·kg−1. The 14 d internal body mass, food intake, organ-body ratios, the serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, blood urea nitrogen, and creatinine were not significantly different by comparing with the normal controls. Therefore, no significant toxicity was observed. CONCLUSION The established standard can provide a reference for evaluating the quality of Triadica cochinchinensis. The heavy metal content of ten batches of medicinal materials is within the safe range. Acute toxicity test show that there is no obvious significant adverse teactions after oral administration, and the safe dose range is large, which can provide a reference for the subsequent development and utilization.

Objective To evaluate the differences in chemical composition and pharmacological effects between Angelica-Astragalus medicine pair decoction(DGD)and traditional decotion,and to provide a reference for the rational clinical application of Danggui Buxue decoction.Methods With the two comparison methods of unified and non-uniform raw material source batches,we set up different sample groups,established characteristic maps by HPLC,and evaluated the chemical components based on the similarity of characteristic maps,component types,index component content,common peak area,and other factors.The efficacy of the drug was evaluated in the hemorrhagic blood deficiency model mice.Results ①The similarity of the feature map between the DGD and TD was high(similarity was greater than 0.87).②The number of chromatographic peaks was inconsistent.Traditional decoction from self-purchased decoction pieces,or traditional decoction-Factory A decoction pieces had a total of 12 chromatographic peaks each.The DGD of Factory A had a total of 15 chromatographic peaks.There were 10 chromatographic peaks in the DGD of Factory B.③The contents of ferulic acid and calycosin 7-O-glucoside(CG)in DGD of Factory A were higher than those in traditional decoction(P<0.05,n=3).There was no significant difference between DGD and TD ferulic acid content in Factory B,but the content of CG was lower than that in traditional decoction(P<0.05).④The total area of common peaks in DGD was different from that in TD.The relative total ratios of the contents of the components in the self-purchased traditional decoction pieces,the traditional decoction pieces of Factory A,the formula granules of Factory A,and the formula granules of Factory B were 1.00,0.96,2.14,0.60,respectively.⑤Both DGD and traditional decoction could significantly promote the recovery of hemoglobin and red blood cells in hemorrhagic anemia model mice(P<0.01);Compared with the model control group,there was a significantly difference(P<0.05)except for the DGD group of Plant B.There was no significant difference between DGD and TD of Plant A,but there was a very significant difference between DGD and TD of Plant B(P<0.01).Conclusion Whether the raw material source batch is consistent or not,DGD and TD have certain differences in chemical composition.In terms of pharmacological effect,DGD,prepared from a unified batch of decoction pieces,has similar efficacy to traditional decoction in alleviating hemorrhagic anemia.There are certain differences in the pharmacological effects between DGD prepared from different batches of decoction pieces and traditional decoctions.The differences caused by the different preparation processes of the same source batch of prepared slices were compared,and the quality differences of the formula granules from different manufacturers were caused by the different source batches of prepared slices and different preparation processes,indicating the necessity and urgency of the country to formulate a unified quality standard for formula granules and related process specifications.
