OBJECTIVE To comprehensively analyze the effectiveness， safety and economic value of carfilzomib in the treatment of multiple myeloma （MM）， and provide evidence-based guidance for clinical rational drug use. METHODS A systematic search was performed in PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang， VIP， and relevant health technology assessment （HTA） websites， from database inception to December 31， 2024. Two researchers independently screened studies based on predefined inclusion and exclusion criteria， extracted data， and assessed study quality. Descriptive statistical analyses were conducted. RESULTS A total of 21 studies were included， comprising 7 systematic reviews/meta-analyses， 5 clinical trials， 5 pharmacoeconomic studies， and 4 HTA reports. Effectiveness analysis indicated that， compared with control groups， carfilzomib significantly improved overall response rate and clinical benefit rate （ P ＜0.05）， prolonged progression-free survival， and enhanced patient’s quality of life （ P ＜0.05）， while its impact on overall survival remains to be further confirmed. Safety analysis showed there was no significant difference in the risk of peripheral neuropathy between carfilzomib and controls， while the risks of cardiotoxicity and hypertension were significantly increased （ P ＜0.05）. Economic analysis suggested that carfilzomib regimens demonstrated certain cost-effectiveness in second-line treatment in the U.S. and some European countries. However， its economic value was influenced by drug price， dosing regimen， and regional differences， and it may lack a cost advantage in some countries or in third-line treatment. CONCLUSIONS Carfilzomib shows definite efficacy and generally acceptable safety in the treatment of MM， but cardiotoxicity and hypertension risks require careful monitoring. Given its high treatment cost， pharmacoeconomic studies in the Chinese population are urgently needed.

Dry eye disease(DED)is a multifactorial disorder with an unclear pathogenesis. Advances in omics technologies have introduced a novel medical research approach, enabling the identification of global response variables from a single-factor perspective. However, multi-omics methods integrate multiple omics datasets to analyze all potential response variables, generating multidimensional and evidence-supported holistic inferences. These insights help elucidate functional impairments of ocular cells and biomolecular processes during disease progression, thereby revealing correlations between biomolecules and complex diseases. This review summarizes the application of multi-omics technologies in clarifying the pathogenesis and intricate molecular mechanisms of dry eye disease. Distinctive features from genomics, transcriptomics, proteomics, metabolomics, and microbiomics are integrated to deepen the understanding of the pathogenesis and complex molecular mechanisms underlying dry eye disease.

ObjectiveTo observe the clinical efficacy of Shentong Zhuyutang combined with Dilongtang in the treatment of lumbar disc herniation （LDH） with Qi stagnation and blood stasis syndrome， and its effect on nucleus pulposus reabsorption and immune-inflammatory factors， exploring its therapeutic mechanism from the perspective of reabsorption. MethodsA total of 120 patients with LDH from the Fourth Clinical Medical College of Guangzhou University of Chinese Medicine， treated between June 2020 and January 2023， were randomly divided into the control group （52 cases， with 8 dropouts） and the observation group （49 cases， with 11 dropouts） according to a random number table. The control group received routine treatment， while the observation group was treated with Shentong Zhuyutang combined with Dilongtang in addition to routine treatment. Visual Analogue Scale （VAS）， Oswestry Disability Index （ODI）， Japanese Orthopaedic Association （JOA） score， and traditional Chinese medicine （TCM） syndrome score were measured before treatment and after 3 courses of treatment. Venous blood samples were collected for the determination of serological indexes. MR examination was performed during the 6-month follow-up to calculate the absorption rate. ResultsAfter treatment， both groups showed significant reductions in VAS， ODI， TCM syndrome score， serum tumor necrosis factor （TNF）-α， matrix metalloproteinase （MMP）-9， and vascular endothelial growth factor （VEGF） levels， and a significant increase in JOA score compared with pre-treatment values （P<0.05）. Compared with the control group， the observation group showed significantly lower VAS， ODI， TCM syndrome score， serum TNF-α， MMP-9， and VEGF levels， and a significantly higher JOA score （P<0.05）. The proportion of nucleus pulposus reabsorption in the observation group was 57.14% （28/49）， significantly higher than 21.15% （11/52） in the control group （χ²=6.161， P<0.05）. ConclusionShentong Zhuyutang combined with Dilongtang can effectively relieve pain， improve lumbar function， and alleviate TCM clinical symptoms in LDH patients with Qi stagnation and blood stasis syndrome. Imaging findings suggest that the treatment promotes the reabsorption of nucleus pulposus protrusion， while laboratory testing shows reduced serum levels of TNF-α， MMP-9， and VEGF， which contribute to the rehabilitation of patients.

Objective To observe the value of non-parallel transmission(non-PTX)reduced field-of-view(rFOV)echo planar imaging(EPI)sequence applied in diffusion weighted imaging(DWI)for displaying prostate lesions.Methods Conventional EPI-DWI and non-PTX rFOV-EPI-DWI were prospectively acquired in 30 patients with prostate lesions,including 22 cases of prostatic hyperplasia and 8 cases of prostate cancer.Subjective scoring of imaging quality,as well as objective evaluation on indexes including signal-to-noise ratio(SNR),contrast ratio(CR),contrast-to-noise ratio(CNR)and lesions'apparent diffusion coefficient(ADC)values were performed and compared between two kinds of DWI.Results The subjective score of non-PTX rFOV-EPI-DWI was higher than that of conventional EPI-DWI(P＜0.001).SNR,CR,CNR of non-PTX rFOV-EPI-DWI and lesions'ADC values measured on non-PTX rFOV-EPI-DWI were all higher than those of conventional EPI-DWI(all P＜0.05).Conclusion non-PTX rFOV-EPI DWI could display prostate lesions better than conventional EPI-DWI.

Background: Optimizing cultivation techniques for traditional Chinese medicine has become a crucial means to improve the quality of medicinal materials. Microbial agents, as environmentally friendly and efficient plant growth promoters and soil conditioners, have increasingly attracted attention in eco-agriculture research. Objective: Our understanding remains limited regarding how the application of microbial agents, alone or in combination, affects changes in the rhizosphere microbiome and its association with the bioactive components of medicinal materials. Methods: In this study, Epimedium pubescens Maxim. was employed as a model plant to examine the effects of 2 microbial agents(Paenibacillus mucilaginosus and Bacillus subtilis) applied individually and in combination on plant growth and the accumulation of bioactive components. Additionally, this study explored the relationship between the rhizosphere microbiome and plant development. Results: The application of microbial agents increased the yield of E. pubescens leaves by 20.30% to 33.66% and enhanced the total flavonol glycosides content by 11.40% to 29.94%. Meanwhile, microbial treatments reshaped the rhizosphere microbiome, promoted the enrichment of beneficial microorganisms (e.g., Frankia and Paenibacillus), suppressed phytopathogenic fungi such as Didymella and Scytalidium, and enhanced the stability of the soil microbial co-occurrence network. The partial least squares path model suggested that microbial agents not only directly impact the quality of medicinal herbs but also indirectly alter the accumulation of bioactive components by modulating the soil microbiome. Conclusion: These findings deepen our understanding of the relationship between medicinal plant quality and rhizosphere microbiomes as mediated by microbial agents. They also provide a basis for designing and manipulating synthetic microbial communities to promote sustainable development in eco-agriculture.

Objective To investigate the influencing factors associated with the risk of positive methylation levels of SHOX2/RASSF1A/PTGER4 genes in patients with pulmonary nodules with TCM susceptibility.Methods Using a cross-sectional study method,totally 165 patients with pulmonary nodules from the Respiratory Department of Wangjing Hospital,China Academy of Chinese Medical Sciences were included from May 2024 to December 2024.Clinical data such as patients'general medical history,nodule imaging reports,lung cancer gene methylation levels,and TCM constitution assessments were organized and statistically analyzed.On the basis of exploring the correlation between various variables and the risk of positive methylation of lung cancer genes through univariate correlation analysis,a binary logistic regression model was used for independent risk factor analysis.Results Univariate correlation analysis showed that age,gender,TCM susceptibility score,diameter of pulmonary nodules and upper lobe of the right lung were correlated with positive methylation levels of the SHOX2/RASSF1A/PTGER4 genes(P=0.03,P=0.02,P=0.01,P<0.01,P=0.03);and binary Logistic regression analysis showed that yang-deficiency quality,qi deficiency,qi depression and phlegm-dampness,the four pulmonary nodules susceptibility body scores were significantly and positively correlated with the risk of SHOX2/RASSF1A/PTGER4 gene methylation positivity.Compared with yang deficiency,phlegm-dampness and qi depression had a higher risk of gene methylation positivity for patients with pulmonary nodules(P=0.04,P=0.02).Conclusion Older age,males,and TCM susceptibility body correlated with the lung cancer gene methylation positive risk are correlated,in which phlegm dampness and qi depression are independent risk factors.

This study aims to investigate the effects of Pulsatilla decoction(PD)on the 5-HT sig-naling system in the hippocampus of damp-heat diarrhoea(DHD)rats.Twenty-four male SD rats were randomly divided into four groups including the blank group,the model group,the PD group and the self-healing group.Except for the blank group,the rats in each group were induced by"high sugar and high fat,high temperature and high humidity,and E.coli poisoning"to establish a of rat model DHD,and were treated by gavage with PD.Changes in body weight,temperature,food intake and water intake,routine blood tests and histopathological changes in the colon were recor-ded to comprehensively determine the modelling condition of rats with DHD;histopathological changes in the hippocampus of rats were observed,and real-time fluorescence PCR was used to de-termine the expression of IL-1β3,IL-6,TNF-α,IFN-γ and TPH1 mRNA in the hippocampus;West-ern blot and immunohistochemistry were used to detect the protein expression of tryptophan hydroxylase 1(TPH1),receptors(5-HT3R,5-HT4R,5-HT7R)in 5-HT signaling pathway in the hippocampus.The results showed that:PD significantly regulated the abnormal changes of body weight,food and water intake and blood routine indexes in rats with DHD,and significantly im-proved the pathological damage of colonic tissues;PD significantly lowered the expression of in-flammatory cytokines IL-1β,IL-6,IFN-γ,and TNF-α in hippocampus of rats with DHD(P＜0.05),and significantly reduced the expression of TPH1 mRNA in hippocampus of rats with DHD(P＜0.05).PD could increased the expression of 5-HT4R and 5-HT7R in the hippocampus of rats with DHD;reduced the expression of 5-HT3R and TPH in the hippocampus,among which 5-HT3R expression was significantly reduced.This study suggests that PD can affect the function of hippocampus in rats with DHD by regulating the 5-HT signaling pathway.
