Liver injury has become an increasingly serious global health problem， and existing chemical drugs face the limitations in efficacy and adverse reactions， resulting in the urgent need to develop safe and effective drugs. Recent studies have highlighted the potential of flavonoids from natural medicinal plants in the prevention and treatment of liver injury. As a typical natural flavonoid， luteolin shows a good protective effect against liver injury due to various etiologies， but there is still a lack of systematic elaboration on its mechanism of action. This article summarizes related research advances in China and globally and reviews the mechanism of action of luteolin in inhibiting oxidative stress， exerting an anti-inflammatory effect， regulating cell death， alleviating hepatic fibrosis， modulating lipid metabolism disorders， and regulating the gut-liver axis， as well as the application prospect of luteolin in the treatment of liver injury， in order to provide a scientific reference for further research on this compound.

The traditional Chinese medicine(TCM) industry is a crucial part of China's pharmaceutical sector and plays a strategic role in ensuring public health and promoting economic and social development. In response to the practical demand for high-quality development of the TCM industry, this paper focused on the bottlenecks encountered during the digital and intelligent transformation of TCM production systems. Specifically, it explored technical strategies and methodologies for constructing the best TCM production mode. An innovative artificial intelligence(AI)-centered technical architecture for TCM production was proposed, focusing on key aspects of production management including process modeling, state evaluation, and decision optimization. Furthermore, a series of critical technologies were developed to realize the best TCM production mode. Finally, a novel AI-driven TCM production mode characterized by a closed-loop system of "measurement-modeling-decision-execution" was presented through engineering case studies. This study is expected to provide a technological pathway for developing new quality productive forces within the TCM industry.

Objective To observe the clinical efficacy and safety of naratinib maleate tablets combined with capecitabine tablets in the treatment of advanced breast cancer patients with human epidermal growth factor receptor 2(HER2)positive.Methods The advanced breast cancer patients with HER2 positive were randomly divided into control group and treatment group.The control group was given 1 250 mg·m-2 capecitabine tablets,bid,orally administered,and stopped for 1 week after 2 weeks of treatment.On the basis of treatment in the control group,the treatment group was treated with a combination of naratinib maleate tablets 240 mg,qd,orally.Both groups of patients continued to take medication until the disease progressed or the patient could not tolerate it,with one course of treatment every three weeks.The clinical efficacy,tumor marker levels,survival status,and the safety was evaluated.Results Treatment group were enrolled 55 cases,1 case dropped out,and 54 cases were finally included in the statistical analysis.Control group were enrolled 55 cases,2 cases dropped out,and 53 cases were finally included in the statistical analysis.After treatment,the disease control rates of treatment and control groups were 64.81％(35 cases/54 cases)and 35.85％(19 cases/53 cases);the objective response rates were 37.04％(20 cases/54 cases)and 18.87％(10 cases/53 cases);the differences were statistically significant(all P＜0.05).After treatment,the levels of carcinoembryonic antigen in the treatment and control groups were(14.88±1.96)and(17.25±2.01)ng·mL-1;the levels of carbohydrate antigen 15-3 were(28.42±4.27)and(32.56±4.85)U·mL-1;the levels of tissue peptide specific antigen were(101.76±10.64)and(106.23±11.16)U·L-1;the overall one-year survival rates were 31.48％and 15.09％;the progression free survival time was 7.00 and 6.00 months;the total survival time was 9.00 and 8.00 months,respectively.The differences of above indexes were statistically significant(all P＜0.05).The adverse drug reactions of two groups were mainly diarrhea,leukopenia,hand foot syndrome,nausea and abdominal pain.The incidences of diarrhea in the treatment and control groups were 79.63％and 60.38％with significant difference(P＜0.05);and there were no significant differences in the incidence of other adverse drug reactions between two groups(all P＞0.05).Conclusion The clinical efficacy of naratinib maleate tablets combined with capecitabine tablets in the treatment of the advanced breast cancer is better than that of capecitabine alone;the former can better reduce the levels of tumor markers,prolong the survival time,and improve the short-term survival rate.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

OBJECTIVE: To investigate the clinical significance of AML patients with 11q23/MLL rearrangement, and to evaluate the effect of those mutations on the AML patients. METHODS: 53 cases involving translocations of chromosome 11q23 were identified by chromosome banding analysis. MLL rearrangements were detected by fluorescence in situ hybridization and/or multiplex nested PCR. The samples were screened for mutations in the candidate genes FLT3-ITD, FLT3-TKD, TET2, N-RAS, ASXLI, EZH2, DNMT3, C-Kit, NPM1, WT1, CEBPA by using genomic DNA-PCR and deep-sequencing. RESULTS: 21/53 MLL-rearranged AML cases showed at least one additional chromosomal aberrations. The most common additional aberration was +8. Gene mutations were observed in 23 cases (43.4%) and most cases showed singal mutation. N-RAS mutation was more frequent (8 cases, 15.1%), followed by WT1 mutation in 4 cases (7.5%), FLT3-ITD mutation in 3 cases, ASXL1 mutation in 2 cases, DNMT3A mutation in 2 cases, EZH2 mutation in 1 case, c-Kit17 mutation in 1 case, FLT3-TKD mutation in 1 case, and FLT3-ITD and TKD mutation coexistent in 1 case. No mutation was detected in CEBPA, NPM1, C-KIT8, TET2. Median OS for gene mutated patients was 8.5 months and 13 months for no mutated patients. Median OS for patients who received hematopoietic stem cell transplantation (HSCT) was 22.5 months and 7.5 months for patients who olny received chemotherapy. CONCLUSION A relatively high mutation frequency is observed in AML patients with 11q23/MLL rearrangements and most cases shows single mutation. The RAS signaling pathway alterations are most common. Gene mutation does not affect the OS of these patients, who show poor prognosis. A significantly higher Hb at initial diagnosis in FLT3 mutated patients is significantly higher than that in FLT3 wild-type cases. Patients who underwent HSCT show a better prognosis than those only received chemotherapy.

This work aimed to investigate the intestinal absorption characteristics of Laportea bulbifera extract in normal and rheumatoid arthritis model rats. The contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutin, kaempferol-3-O-rutinoside, galuteolin, quercetin and isoquercetin in intestinal absorption solution samples were detected by UPLC-MS/MS with 5.0 g·L~(-1) as the absorption concentration. The cumulative absorption(Q) and absorption rate constant(K_a) were calculated, and the absorption characteristics of different components of L. bulbifera in intestinal absorption solution of normal rats and rheumatoid arthritis rats were compared. The results showed that all the eight index components in the extract of L. bulbifera could be absorbed into the intestinal capsule, the cumulative absorption-time curve of each component showed an upward trend without saturation, and the correlation regression coefficient(R~2) was greater than 0.92, which is consistent with the zero-order absorption rate process. It was speculated that the possible absorption mode of each component was passive diffusion. In normal condition, the absorption of ileum was the best(except chlorogenic acid), and in pathological condition, duodenum was the best. The total absorption of 8 components in each intestinal segment of RA rats was better than that of normal rats, which speculated that rheumatoid arthritis may change the specific site of drug absorption. The experimental results showed that rheumatoid arthritis could change the intestinal absorption of the extract of L. bulbifera, and its mechanism needs further study.
