Objective:To study the effect of traditional Chinese medicine (TCM) formula in the treatment of brucellosis.Methods:Patients with brucellosis who were treated at the Beidahuang Industry Group General Hospital from March to November 2024 were selected and their clinical data were collected. A case-control study was conducted, thirty patients treated with conventional therapy plus TCM formula were selected as the TCM group, and 35 patients treated with conventional therapy were selected as the control group. Blood routine, C-reactive protein (CRP), lymphocyte subsets (CD45 +, CD3 +, CD4 +, CD8 +, CD19 +), and related cytokines [interleukin (IL)-6, IL-10] were determined before and after treatment to observe the clinical effect of TCM formula in the treatment of brucellosis. Survival curve was draw, and Log-Rank test was used to compare the differences in clinical symptom relief time between the two groups of patients. Results:Compared with pre-treatment, there were statistically significant differences in the numbers of CD45 +, CD3 +, CD4 +, CD8 +, CD19 + lymphocytes, neutrophil (NEUT), and the levels of CRP, IL-6, and IL-10 in the TCM group after treatment ( P < 0.05). After treatment, the comparison of each index between the two groups showed that there were statistically significant differences in the numbers of CD45 +, CD3 +, CD4 +, and CD8 + lymphocytes [control group vs TCM group: 2 470.00 (1 895.50, 3 207.00) vs 1 991.00 (1 720.75, 2 367.25), 1 920.00 (1 364.50, 2 428.00) vs 1 591.00 (1 343.00, 1 884.00), 1 021.00 (785.00, 1 205.50) vs 839.50 (704.25, 1 010.25), (686.42 ± 294.47) vs (596.97 ± 205.32) pieces/μl, P < 0.05]. There was no statistically significant difference in the number of CD19 + lymphocytes, NEUT, and the levels of CRP, IL-6 and IL-10 ( P > 0.05). The Log-Rank test results showed that there were statistically significant differences in the relief time of hyperhidrosis and night sweats ( P = 0.016), fatigue ( P = 0.016), and muscle soreness ( P = 0.004) between the two groups of patients. Conclusion:TCM formula has certain effects in the adjuvant therapy of brucellosis, which can improve the immune function of lymphocytes and relieve clinical symptoms, and has clinical application value.

Objective:To explore the clinical characteristics of patients with brucellosis complicated with epididymo-orchitis (Brucellar epididymo-orchitis, BEO), so as to provide reference for clinical diagnosis and treatment of BEO.Methods:General and clinical data of 293 male patients with acute brucellosis admitted to the Beidahuang Industry Group General Hospital from January 2023 to December 2024 were retrospectively collected. They were divided into a BEO group (30 cases) and a non-BEO group (263 cases) based on the presence or absence of epididymo-orchitis. Epidemic characteristics, clinical manifestations and laboratory examination results were compared and analyzed.Results:Among 293 male patients with acute brucellosis, the incidence of BEO was 10.24% (30/293). Their age was mainly concentrated in 45 - < 60 years old (53.33%, 16/30), and occupation was mostly farmers (63.33%, 19/30). There were no statistically significant differences in the distribution of age, occupation, exposure history and onset season between the BEO group and the non-BEO group ( P > 0.05). The distribution of abdominal pain and urinary frequency/urgency/pain symptoms was compared, and the differences were statistically significant ( P < 0.05). White blood cell count (WBC), neutrophil count (NEUT), and C-reactive protein (CRP) levels in the BEO group were higher than those in the non-BEO group ( P < 0.05), while the levels of cytokines interleukin (IL)-6 and interferon-γ (IFN-γ) were lower than those in the non-BEO group ( P < 0.05). After 6 - 8 weeks of hospitalization, the levels of WBC, NEUT, CRP, albumin, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transpeptidase, alkaline phosphatase, α-hydroxybutyrate dehydrogenase, lactate dehydrogenase, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor-α, and IFN-γ in patients of the BEO group were significantly different from before treatment ( P < 0.05). Twenty-eight patients were cured, 1 patient underwent orchiectomy, and 1 patient experienced recurrence. Conclusions:Middle-aged male patients with brucellosis are more prone to BEO. Clinical manifestations and laboratory tests have certain diagnostic value for BEO. Suspected BEO patients should be diagnosed and treated as early as possible to reduce the occurrence of adverse prognosis.

Objective:To learn about the levels of 25-hydroxy vitamin D (25-OH VD), TBNK lymphocyte subsets, and cytokines in peripheral blood of patients with brucellosis.Methods:A prospective design was adopted, one hundred patients with brucellosis admitted to the Department of Infectious Diseases, Beidahuang Industry Group General Hospital from May 2024 to February 2025 were selected as the brucellosis group, and one hundred healthy individuals who underwent physical examinations at the hospital during the same period were selected as the control group. The peripheral blood 25-OH VD levels were detected by chemiluminescence method. Further, 100 patients with brucellosis were divided into a brucellosis combined with osteoarthritis group (74 cases) and a brucellosis without osteoarthritis group (26 cases). Flow cytometry was used to detect the counts of peripheral blood TBNK lymphocyte subsets and cytokine levels. Meanwhile, Spearman rank correlation was used to analyze the correlation between peripheral blood 25-OH VD levels and TBNK lymphocyte subsets counts as well as cytokine levels in patients with brucellosis complicated by osteoarthritis.Results:The peripheral blood 25-OH VD level in the brucellosis group [20.31 (15.74, 24.35) ng/ml] was significantly lower than that of the control group [25.18 (21.13, 29.59) ng/ml], and the difference was statistically significant ( Z = - 5.07, P < 0.001). The peripheral blood 25-OH VD level [18.05 (13.79, 23.74) vs 22.43 (19.93, 28.25) ng/ml], CD4 + T cell count [(860 ± 275) vs (1 036 ± 376) cells/μl], and interleukin (IL)-6 levels [4.17 (2.14, 9.41) vs 7.83 (5.97, 11.34) ng/L] in the brucellosis combined with osteoarthritis group were significantly lower than those in the brucellosis without osteoarthritis group ( Z/t = - 2.88, 2.20, - 2.85, P = 0.004, 0.035, 0.004). Correlation analysis showed that the peripheral blood 25-OH VD level in patients with brucellosis complicated by osteoarthritis was positively correlated with the counts of CD45 +, CD3 + T, CD4 + T, CD8 + T, and natural killer cells ( r = 0.31, 0.26, 0.25, 0.25, 0.25, P = 0.007, 0.027, 0.032, 0.031, 0.032), and negatively correlated with IL-17A level ( r = - 0.40, P < 0.001). Conclusion:Patients with brucellosis have insufficient 25-OH VD, and those with osteoarthritis have lower 25-OH VD level, CD4 + T cell count, and IL-6 level than those without osteoarthritis.

Objective:To explore the correlation between ASXL1 gene mutation characteristics and clinical manifestations and prognosis in patients with myelodysplastic syndrome(MDS).Methods:The clinical date of 264 patients with MDS in Xuzhou Central Hospital,Southeast University from August 2010 to April 2024 was retrospectively analyzed.The patients were divided into ASXL1wt group and ASXL1mut group according to the presence of ASXL1 gene mutation,and the correlation between gene mutation characteristics and clinical manifestations and prognosis was analyzed.Results:Compared with ASXL1wt group,the ASXL1mut group had a higher age of onset(P＜0.05),a higher proportion of males(P＜0.05),while the incidence of del(5q)was lower(P＜0.01).The mutation frequency of ASXL1 in MDS patients was 21.97％,and most of them were frameshift mutations.The p.Gly646fs was the most common amino acid variant,with a mutation frequency of 20.69％.The median overall survival(OS)and leukemia-free survival of patients with this sequence variant was 18.1 and 23.8 months,respectively,while in those without this sequence variant was 30 months and not reached,and the differences were statistically significant(P＜0.05).The results of multivariate analysis showed that the mutation of NRAS,WT1,KIT gene and the p.Gly646fs sequence mutation of ASXL1 gene were independent prognostic factors for OS in ASXL1mut patients.The median OS of ASXL1wt and ASXL1mut patients was 27.9(21.3-40.4)and 23.7(18.6-NA)months,respectively(P＞0.05).Among 58 ASXL1mut patients,5 cases(8.6％)transformed to acute leukemia,including 3 cases with RUNX1 mutation and 3 cases with TET2 mutation.Among 206 ASXL1wt patients,28 cases(13.6％)transformed to acute leukemia.The difference in leukemia transformation rate between the two groups was not statistically significant(P＞0.05).The efficacy of different treatment regimens was similar in the ASXL1mut group,while in the ASXL1wt group,patients receiving allogeneic hematopoietic stem cell transplantation had a significantly better prognosis than those receiving other treatment regimens(P＜0.001).The overall response rate to demethylation therapy was 68.7％and 67.6％in ASXL1mut and ASXL1wt group,respectively,and the difference between the two groups was not significant(P＞0.05).Conclusion:The overall survival of MDS patients with ASXL1mut is poor.The patients with p.Gly646fs sequence mutation have a higher proportion of bone marrow blasts and a worse prognosis.There are no statistical differences in efficacy of different treatment strategies in ASXL1mut group.ASXL1 mutation shows no significant effect on the response of MDS to hypomethylating agent therapy.

Under the background of carbon peaking and carbon neutrality goals, the Ministry of Ecology and Environment, together with 15 national ministries and commissions, has formulated the Implementation Plan on Establishing a Carbon Footprint Management System, and it is urgent for traditional Chinese medicine(TCM) pharmaceutical enterprises to carry out research on carbon footprint accounting methods of related products. Based on the life cycle assessment(LCA) theory, taking mulberry leaf extract produced by a certain enterprise as an example, this study analyzed the carbon footprint of TCM extracts during the life cycle. The results show that for every 1 kg of product produced, the carbon emissions from the stages of raw material acquisition, transportation, and extract production are-20.569, 1.205, and 173.577 kgCO_2eq(CO_2 equivalent), respectively. The carbon footprint of the product is 154.213 kgCO_2eq·kg~(-1). In addition, the carbon emission is the highest in the production stage, in which the consumption of ethanol solvents makes the greatest contribution to the carbon footprint, accounting for 25.71%, more than one-fourth of the total carbon footprint. The second contribution was from the treatment process of TCM residues, accounting for 19.67%, closely followed by wastewater treatment(17.71%), the consumption of hot steam(17.43%), and drinking water(16.90%). The consumption of electric power and packaging materials has a smaller carbon emission of 2.58%. In particular, the carbon emission caused by the consumption of packaging materials is only 0.04%, which is negligible. The results of the study are expected to provide a reference for TCM enterprises to carry out research on the carbon footprint of products, offer ideas for collaborative innovation in reducing pollution and carbon emissions throughout the entire industry chain of TCM, and develop new quality productivity of modern TCM industry based on green and low-carbon manufacturing.

This study investigated the functions and regulatory mechanism of Portulacae Herba and its chemical components on the Toll-like receptor 4(TLR4)/myeloid differentiation primary response 88(MyD88)/nuclear factor kappa B(NF-κB) inflammatory signaling pathway in the colon tissue of mice with dextran sodium sulfate(DSS)-induced ulcerative colitis(UC). A total of 35 mice were randomly divided into groups, including a blank group, a model group, a mesalazine group(0. 5 g·kg~(-1)), and low, medium,and high dose alkaloids from Portulacae Herba groups(9, 18, 36 mg·kg~(-1)), and a combination treatment group, with 5 mice in each group. The blank group was given purified water, while the other groups were continuously given a 3% DSS solution for 7 days to induce the UC model. From day 8 onwards, the treatment group received oral gavage according to the prescribed doses for 14 days. The overall condition, body weight, stool characteristics, and presence of blood in the stool were recorded daily. After the experiment, the disease activity index(DAI) was assessed for each group, and colon length was measured. Histopathological changes in colon tissue were examined using hematoxylin-eosin(HE) staining. The levels of pro-inflammatory cytokines, tumor necrosis factor-α(TNF-α),and interleukin-1β( IL-1β) in serum were measured by enzyme-linked immunosorbent assay( ELISA). The protein and m RNA expression of TLR4, MyD88, and NF-κB in colon tissue were measured using Western blot and quantitative real-time PCR(qPCR).Compared to the blank group, the model group showed a significant decrease in body weight, a notable increase in DAI scores, a significant shortening of colon length, and evident histopathological damage. The levels of inflammatory cytokines TNF-α and IL-1β in the serum were significantly elevated, and the protein and m RNA expression of TLR4, MyD88, and NF-κB in colon tissue were significantly up-regulated. In contrast, the alkaloids from Portulacae Herba treatment groups significantly improved symptoms and reduced body weight loss in mice, decreased DAI scores, alleviated colon shortening, lowered serum levels of TNF-α and IL-1β,significantly down-regulated the expression levels of TLR4, MyD88, and NF-κB proteins and genes in colon tissue, as well as reduced histopathological damage. Therefore, the study suggests that alkaloids from Portulacae Herba can alleviate intestinal inflammation damage in DSS-induced UC mice, with its mechanism involving the TLR4/MyD88/NF-κB signaling pathway.

Traditional Chinese medicine(TCM) processing is a specialized pharmaceutical technique with the primary objective of reducing the toxicity of medicinal substances. Euphorbia pekinensis, E. ebracteolata, and E. fischeriana, all belonging to Euphorbiaceae, are classified as drastic purgative herbs, traditionally used for eliminating retained water, reducing swelling, resolving toxicity, and dispersing masses. However, these herbs are also associated with adverse effects such as abdominal pain and diarrhea. Accordingly, they are commonly processed with vinegar, milk, or Terminalia chebula decoction to reduce the toxicity. This review summarizes the chemical constituents, pharmacological activities, historical evolution of processing methods, and detoxification mechanisms of the three toxic Euphorbia species. The primary toxic constituents are terpenoids. Specifically, E. ebracteolata and E. fischeriana are rich in diterpenoids, while E. pekinensis contains diterpenoids, triterpenoids, and sesquiterpenoids. Studies have shown that vinegar processing promotes structural transformations of diterpenoids, including ether bond hydrolysis, lactone ring opening, esterification, oxidation, and epoxide ring cleavage, thereby reducing the content and toxicity of these compounds. Milk processing facilitates the dissolution of toxic components into the residual liquid of excipients, leading to decreases in their concentrations in the final decoction pieces. Processing with T. chebula decoction raises the levels of tannin-derived phenolic acids, which antagonize the adverse effects of the intestine. These findings reveal a shared detoxification pattern among the three toxic herbs. Accordingly, this review proposes the concept of a shared detoxification mechanism for toxic herbs belonging to the same family or genus. That is, toxic herbs belonging to the same taxon often exhibit similar toxicological profiles and can undergo detoxification through the same processing methods, reflecting common underlying mechanisms. Investigating such shared mechanisms across multiple species of the same genus offers a promising research strategy. Ultimately, the research into processing-induced detoxification mechanisms provides both theoretical and practical support for ensuring the safety of toxic TCM.
