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.

OBJECTIVE: To observe the effect of Guilu Taohong Formula on semen quality in varicocele (VC) models of rats, and to explore its possible mechanism. METHODS: Forty-eight male SD rats were randomly divided into four groups (sham group, model group, Guilu Taohong Formula group and L-carnitine group). After the establishment of models, the rats were treated with intragastric administration for eight consecutive weeks. The general condition of the rats was observed. After the gavage, the testicular and epididymal indices were calculated. Semen quality was assessed using an automatic semen analyzer. Apoptosis of testicular cells was assessed by TUNEL staining. And the expression levels of B-cell lymphocytoma-2 (Bcl-2), Bcl-2-associated X protein (Bax) and cysteine aspartate protease-3 (caspase-3) in testicular tissue were detected by Western blot. RESULTS: Compared with the sham group, testicular index, epididymal index, sperm concentration, the percentage of progressive motility of sperm (PR%) and the expression level of Bcl-2 decreased in model group(P<0.01). An increased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins were observed in model group as well(P<0.01). Compared with the model group, the testicular index, epididymal index, sperm concentration, PR% and the expression level of Bcl-2 in Guilu Taohong Formula group increased significantly (P<0.05, P<0.01). A decreased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins were detected in Guilu Taohong Formula group as well(P<0.01). Similarly, the L-carnitine group showed increased testicular index, epididymal index, sperm concentration, PR% and the expression level of Bcl-2 protein (P<0.05, P<0.01), where showed decreased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins compared with model group (P<0.01, P<0.05). CONCLUSION Guilu Taohong Formula improves semen quality in VC model rats and reduces the apoptosis rate of spermatogenic cells in testicular tissue, which may be related to the promotion of Bcl-2 protein expression and the inhibition of Bax and caspase-3 protein expression levels.

OBJECTIVE: To investigate the association between ABO blood types and gestational diabetes mellitus (GDM) risk. METHODS: A prospective birth cohort study was conducted. ABO blood types were determined using the slide method. GDM diagnosis was based on a 75-g, 2-h oral glucose tolerance test (OGTT) according to the criteria of the International Association of Diabetes and Pregnancy Study Groups. Logistic regression was applied to calculate the odds ratios ( ORs) and 95% confidence intervals ( CIs) between ABO blood types and GDM risk. RESULTS: A total of 30,740 pregnant women with a mean age of 31.81 years were enrolled in this study. The ABO blood types distribution was: type O (30.99%), type A (26.58%), type B (32.20%), and type AB (10.23%). GDM was identified in 14.44% of participants. Using blood type O as a reference, GDM risk was not significantly higher for types A ( OR = 1.05) or B ( OR = 1.04). However, women with type AB had a 19% increased risk of GDM ( OR = 1.19, 95% CI = 1.05-1.34; P < 0.05), even after adjusting for various factors. This increased risk for type AB was consistent across subgroup and sensitivity analyses. CONCLUSION The ABO blood types may influence GDM risk, with type AB associated with a higher risk. Incorporating it-either as a single risk factor or in combination with other known factors-could help identify individuals at risk for GDM before or during early pregnancy.

A liquid chromatography-tandem mass spectrometry(LC-MS/MS)method was developed for determination of three kinds of β-agonists(Clenbuterol(CL),Ractopamine(RAC)and Salbutamol(SAL))residues in animal liver samples.The liver sample homogenates were extracted with organic solvent,followed by clean-up using the automatic magnetic solid-phase extraction(MSPE),and then analyzed using LC-MS/MS.The results showed that the magnetic mixed-mode cation exchange adsorbent(M-MCX)exhibited 34%higher adsorption capacity than the conventional mixed-mode cation exchange(MCX)column.Furthermore,the clean-up was conducted by using an automatic MSPE device,and 8 samples could be simultaneously treated within 30 min.The limits of detection(LOD)were 0.01-0.1 μg/kg,the average recoveries ranged from 88.2%to 110.5%,and the relative standard deviations(RSDs)were in range of 2.9%-10.3%at three spiked levels for the three kinds of β-agonists.Compared with the traditional SPE technique,the present method had many advantages such as simple operation,rapidity and high efficiency,which was suitable for high-throughput and automatic detection of residues in routine analysis.

Objective:To investigate the clinical effect of endoscopic injection of norepinephrine on cerebral infarction complicated by stress-induced gastrointestinal bleeding.Methods:A total of 150 patients with cerebral infarction complicated by stress-induced gastrointestinal bleeding who were admitted to the Intensive Care Unit of Lishui City People's Hospital from October 2020 to October 2021 were included in this study. These patients were randomly divided into a control group and an observation group using the random number table method, with 75 patients in each group. Patients in the control group received routine clinical treatment, while those in the observation group received endoscopic injection of norepinephrine in addition to routine clinical treatment. The hemostatic time, blood transfusion volume, and length of hospital stay were compared between the two groups. The stress index and inflammatory index were compared between the two groups before and after treatment. The hemostatic effect and adverse reactions were evaluated in each group.Results:The hemostatic time, blood transfusion volume, and length of hospital stay in the observation group were (16.16 ± 4.36) hours, (385.35 ± 41.28) mL, and (5.35 ± 1.28) days, respectively, which were significantly shorter or less than (27.27 ± 6.34) hours, (447.07 ± 32.07) mL, and (7.07 ± 2.07) days in the control group ( t = 12.50, 10.22, 6.12, all P < 0.001). After treatment, the levels of cortisol, norepinephrine, antidiuretic hormone, high-sensitivity C-reactive protein, interleukin-6, and tumor necrosis factor-α in the observation group were (288.33 ± 19.53) mmol/L, (29.17 ± 4.26) μg/L, (4.08 ± 1.08) mU/L, (38.27 ± 8.72) ng/L, (6.69 ± 1.35) μg/L, and (6.37 ± 1.51) mg/L, respectively, which were significantly lower than (327.22 ± 22.01) mmol/L, (39.32 ± 5.54) μg/L, (5.36 ± 1.22) mU/L, (51.24 ± 13.23) ng/L, (8.67 ± 2.29) μg/L, and (11.44 ± 3.13) mg/L in the control group ( t = 11.44, 12.57, 6.80, 7.08, 6.45, 12.63, all P < 0.001). The overall response rate of hemostasis in the observation group was 94.67% (71/75), which was significantly higher than 82.67% (62/75) in the control group ( χ2 = 5.37, P < 0.05). The incidence of adverse reactions in the observation group was 8.00% (6/75), which was slightly, but not significantly, lower than 14.67% (11/75) in the control group ( χ2 = 1.66, P > 0.05). Conclusion:Endoscopic injection of norepinephrine for the treatment of cerebral infarction complicated by stress-induced gastrointestinal bleeding can rapidly stop bleeding, effectively reduce inflammation,improve stress index, and be highly safe.

Objective:To investigate the molecular mechanism and distribution characteristics of RhD negative phenotypes in Han population of blood donors in Wuhu city.Methods:A total of 210 RhD-samples from August 2021 to August 2022 were screened by serological test and collected from Wuhu Central Blood Station for the voluntary blood donor population.Exons 1 and 10 of the RHD gene were amplificated by PCR to determine whether the samples had the RHD gene.Exons 1-10 of the RHD gene were amplificated by PCR and zygosity analysis were performed in 82 samples containing D gene,and Sanger sequencing was performed on 55 samples containing all RHD exons to determine the genotype.Results:Among 210 RhD-specimens,128 cases(60.38％)had RHD gene deletion.27 cases had partial exons of RHD,including 2 cases with RHD*DVI.3/RHD*01N.01,24 cases with RHD*01N.04/RHD*01N.01,and 1 case with RHD-CE(2-10)/RHD*01N.01.55 cases had retained all of 10 exons,including 4 cases with RHD*01/RHD*01N.01,6 cases with RHD*15/RHD*01N.01,1 case with RHD*01W.72/RHD*01N.01,1 case with RHD*15/RHD*01EL.01,39 cases with RHD*01EL.01/RHD*01N.01,and the remaining 4 cases were determined to have no RHD gene deletion by zygosity analysis and sequencing showed the presence of 1227G＞A mutation loci.Conclusion:There is polymorphism in the molecular mechanism of RhD-D gene in Wuhu blood donor population,among which RHD*01EL.01 and RHD*15 are the main variants in this region.The results of this study provide a theoretical basis for RhD blood group identification and clinical blood transfusion in this region.

Inflammatory bowel disease(IBD)is a kind of immune disease.Although immune cells and related immunological reactions play a crucial role in the pathogenesis,non-immune cells of IBD,including intestinal epithelial cells,stromal cells,and endothelial cells are also involved in this process.Recent studies have shown that gut non-immune cells play an important role in the maintenance of intestinal epithelial homeostasis,matrix remodeling,immune response and inflammation.The composition,gene expression characteristics and cell functions of gut non-immune cells,as well as their role in the occurrence and progression of IBD,have been paid much attention in the field of gut research.In particular,recently,single-cell RNA sequencing(scRNA-seq)technology has initially clarified the gene expression characteristics and cell functions of different subgroups of intestinal cells,and the correlation between these changes and the occurrence and progression of IBD.Therefore,this review summarizes the progress of intestinal non-immune cells in IBD.

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.

Public health interventions refer to a series of organized and specific measures implemented in specific situations to achieve goals related to improving health, preventing and controlling diseases, and more. As research on intervention measures has deepened, the classification of public health interventions has gradually developed, clarifying the nature, categories and intervention targets of these measures. This typological study can help standardize the concepts of public health interventions, develop, select, and evaluate the effectiveness of intervention measures, and improve the effectiveness of public health actions. This paper reviews the main international classification models of intervention measures, analyzes and summarizes five classification methods of public health interventions, namely, based on goals, nature, objects, hierarchies, and modes of action, and introduces relevant cases. The paper proposes that China should conduct further in-depth and systematic research on public health interventions, develop evidence-based intervention measures and practices, promote the effective transformation of intervention measures and results, and facilitate the development of public health.

Objective: To analyze the incidence of preterm birth based on pre-pregnancy body mass index (BMI) stratification and explore the associated factors of preterm birth among pregnant women at different BMI stratifications. Methods: From February 2018 to December 2020, pregnant women who participated in China Birth Cohort Study (CBCS) and gave birth at Beijing Obstetrics and Gynecology Hospital were enrolled as the study subjects. Electronic Data Capture System and standard structured questionnaires were used to collect data related to pre-pregnancy, pregnancy, and delivery for pregnant women. Pregnant women were divided into the low-weight group, normal-weight group and overweight group based on their pre-pregnancy BMI. A Cox proportional hazards model was used to analyze the associated factors of preterm birth among pregnant women with different BMI before pregnancy. Results: A total of 27 195 singleton pregnant women were included, with a preterm birth rate of 5.08% (1 381/27 195). The preterm birth rates in the low-weight group, normal-weight group and overweight group were 4.29% (138/3 219), 4.63% (852/18 390) and 7.00% (391/5 586) respectively (P<0.001). After adjusting for relevant factors, the Cox proportional hazards model showed that the risk of preterm birth in the overweight group was 1.457 times higher than that in the normal-weight group (95%CI: 1.292-1.643). Preeclampsia-eclampsia (HR=2.701, 95%CI: 1.318-5.537) was the associated factor for preterm birth in the low-weight group. Advanced maternal age (HR=1.232, 95%CI: 1.054-1.441), history of preterm birth (HR=4.647, 95%CI: 3.314-6.515), vaginal bleeding in early pregnancy (HR=1.613, 95%CI: 1.380-1.884), and preeclampsia-eclampsia (HR=3.553, 95%CI: 2.866-4.404) were associated factors for preterm birth in the normal-weight group. Advanced maternal age (HR=1.473, 95%CI: 1.193-1.818), history of preterm birth (HR=3.209, 95%CI: 1.960-5.253), vaginal bleeding in early pregnancy (HR=1.636, 95%CI: 1.301-2.058), preeclampsia-eclampsia (HR=2.873, 95%CI:2.265-3.643), and pre-gestational diabetes mellitus (HR=1.867, 95%CI: 1.283-2.717) were associated factors for preterm birth in the overweight group. Conclusion: Pre-pregnancy overweight is an associated factor for preterm birth, and there are significant differences in the associated factors of preterm birth among pregnant women with different BMI before pregnancy.
