In the quality control of Chinese medicine, the detection of active components and toxic and harmful components are two important links. Although conventional methods such as high performance liquid chromatography and liquid chromatography-mass spectrometry can accurately quantify the above substances, they have shortcomings such as complicated operation, high costs, inability of detection at any time, difficult detection of insoluble and macromolecular substances. Enzyme-linked immunosorbent assay (ELISA) can adsorb antigens or antibodies on the surface of solid carriers and realize qualitative or quantitative analysis of targets by using the specific reactions of antigens and antibodies. This method is praised for the simple operation, high sensitivity, strong specificity, simple requirements for experimental equipment, a wide application range, and low costs. In recent years, ELISA has been widely used in the quality control of Chinese medicine, especially in the content determination of mycotoxins represented by aflatoxin and the qualitative and quantitative analysis of active components. ELISA plays an increasingly important role with its unique advantages, providing new methods and ideas for the rapid quality examination of large quantities of Chinese medicines. This paper reviews the research progress in ELISA for the quality control of Chinese medicine in recent years and prospects its technical development and application prospects, aiming to provide reference and research ideas for further using this method to ensure the quality, safety, and controllability of Chinese medicine.

Background:
SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood.
Methods:
We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival.
Results:
Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity.
Conclusions
The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

Objective:To analyze the clinical characteristics and risk stratification of 182 patients with acute pulmonary embolism (APE), and to investigate the correlation of neutrophil (N)/lymphocyte (L) ratio (NLR) and risk stratification/prognosis.Methods:The clinical data of 182 APE patients admitted to Peking University People’s Hospital from January 2015 to March 2021 were retrospectively collected, including age, sex, symptoms and signs, blood pressure, blood gas analysis, blood routine parameters, cardiac biomarkers, coagulation parameters, and right ventricular imaging parameters. The patients were divided into groups according to the risk stratification at admission and prognosis in hospital. χ2 test, t test or nonparametric test were used to analyze the differences in clinical characteristics, blood routine parameters, blood gas analysis, coagulation parameters and other parameters between the groups. Multivariate logistic regression analysis was used to study the independent risk factors for the prognosis of APE. Results:Among the 182 patients, 79 were male and 103 were female, 23 were in the high-risk group, 51 were in the intermediate-high-risk group, 46 were in the intermediate-low risk group, and 62 were in the low-risk group. There were 27 deaths and 155 survivors. The respiratory rate of the high/intermediate-high-risk group was significantly higher than that of the low/intermediate-low-risk group. Compared with the other three groups, pH, oxygen partial pressure (PO 2) and blood oxygen saturation (SO 2) in the high-risk group were significantly lower ( both P<0.05). There were statistically significant differences in WBC, N, and NLR levels between the high/intermediate-high-risk group and low/intermediate-low-risk group ( both P<0.05). However there were no significant differences in PLT, PLT/MPV, PLT/PDW, and coagulation related parameters PT, FIB, APTT and D-D between groups (all P > 0.05). MPV and PDW were only significantly different between the low-risk group, intermediate-low-risk group and high-risk group ( both P<0.05). Multivariate logistic regression analysis showed that NLR ( OR=1.179,95% CI:1.029-1.410, P=0.039) and PH ( OR=1.156,95% CI:1.031-1.522, P=0.041) were independent predictors of in-hospital mortality. The ROC curve was used to analyze the predictive value of NLR for in-hospital mortality. When the cutoff value of NLR was 8.38, the AUC of NLR was 0.824 (95% CI: 0.829-0.913), the corresponding sensitivity was 0.831, and the specificity was 0.887. Conclusions:NLR is correlated with risk stratification and prognosis of APE, and is an independent risk factor for poor prognosis.

Objective:To understand the duration of survival and related influencing factors of HIV/AIDS patients in Liuzhou city.Methods:Both life table method and Kaplan-Meier method were used to calculate the average survival time of HIV/AIDS patients aged ≥15 years reported in Liuzhou city from 2008 to 2018. Factors related to the duration of HIV/AIDS patients were analyzed by univariate and multivariate Cox regression models.Results:A total of 14 856 patients with HIV/AIDS were involved in this study and with the average duration of survival time as 98.74 (95 %CI: 97.73-99.75) months. The cumulative survival rates of 1, 3, 5 and 10 years were 77.0%, 72.0%, 68.0%, 61.0% respectively. Results from the multivariate Cox proportional risk regression analysis showed that factors as sex, level of education, age when HIV infection was confirmed, occupation, route of transmission, source of samples, results of the first CD 4 test and antiviral treatment were all related to the duration of survival to the HIV/AIDS patients. Conclusions:Strategies involving early detection of HIV infection, improvement of the CD 4 initial detection rate and early antiviral treatment will help to significantly reduce the risk of death in HIV/AIDS population. Focus should be on male, middle-aged and elderly (over 41 years old), junior high school education or below farmers and migrant worker populations.

Genome reannotation aims for complete and accurate characterization of gene models and thus is of critical significance for in-depth exploration of gene function. Although the availability of massive RNA-seq data provides great opportunities for gene model refinement, few efforts have been made to adopt these precious data in rice genome reannotation. Here we reannotate the rice (Oryza sativa L. ssp. japonica) genome based on integration of large-scale RNA-seq data and release a new annotation system IC4R-2.0. In general, IC4R-2.0 significantly improves the completeness of gene structure, identifies a number of novel genes, and integrates a variety of functional annota-tions. Furthermore, long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs) are system-atically characterized in the rice genome. Performance evaluation shows that compared to previous annotation systems, IC4R-2.0 achieves higher integrity and quality, primarily attributable to mas-sive RNA-seq data applied in genome annotation. Consequently, we incorporate the improvedannotations into the Information Commons for Rice (IC4R), a database integrating multiple omics data of rice, and accordingly update IC4R by providing more user-friendly web interfaces and implementing a series of practical online tools. Together, the updated IC4R, which is equipped with the improved annotations, bears great promise for comparative and functional genomic studies in rice and other monocotyledonous species. The IC4R-2.0 annotation system and related resources are freely accessible at http://ic4r.org/.
