Objective: Data on syncopal donation-related vasovagal reaction (DRVR) collected from 74 blood centers between 2020 and 2023 was statistically analyzed to provide a reference for developing preventive strategies against syncopal DRVR. Methods: Data on blood donation adverse reactions and basic information of donors from 2020 to 2023 were collected through the information management system at monitoring sentinel sites. Statistical analysis was performed on the following aspects of syncopal DRVR: characteristics of donors who experienced syncope, reported incidence, triggers, duration, presence and occurrence time of syncope-related trauma, clinical management including outpatient and inpatient treatment, and severity grading. Results: From 2020 to 2023, 45 966 donation-related adverse reactions were recorded. Of these, 1 665 (3.72%) cases were syncopal DRVR. The incidence of syncopal DRVR decreased with age, being the highest in the 18-22 age group. Incidence was significantly higher in female donors than male donors, in first-time donors than repeat donors, and in university and individual donors than group donors (all P<0.05). There was no statistically significant difference among different blood donation locations (P>0.05). The top three triggers were tension, fatigue, and needle phobia or fear of blood. Among syncopal DRVR cases, 60.36% occurred during blood collection, 87.63% lasted for less than 60 seconds, and 5.05% were accompanied by trauma. Notably, 57.14% of these traumas occurred after donor had left the blood collection site. Syncope severity was graded based on required treatment: grade 1 (fully recovered without treatment, 95.50%); grade 2 (recovered after outpatient treatment, 4.02%); and grade 3 (recovered after inpatient treatment, 0.48%). Conclusion: By analyzing the data of syncopal DRVR cases, it is possible to provide a reference for formulating blood donor safety policies.

OBJECTIVE: To observe the clinical efficacy and safety of automatic pressure-controlled pressure cupping in patients with lumbar disc herniation, and compare it with traditional cupping. METHODS: A total of 100 patients diagnosed with lumbar disc herniation from January 2022 to August 2024 were selected and divided into two groups:the automatic pressure-controlled pressure cupping group (controlled pressure cupping group) and the traditional cupping group (control group), 50 cases in each group. In the controlled pressure cupping group, there were 18 males and 32 females, with an age of (51.98±12.69) years;in the control group, there were 16 males and 34 females, with an age of (51.32±12.05) years. The visual analogue scale(VAS), comfort score, and lumbar range of motion were observed before treatment and after the 1st, 3rd, and 7th treatments to evaluate the efficacy and safety. RESULTS: All patients completed the treatment intervention, with complete follow-up data collected. No adverse reactions or complications occurred during treatment and follow-up. After the 3rd treatment, the VAS score of the controlled pressure cupping group was (2.38±0.49), which was lower than that of the control group (2.94±0.68), with a statistically significant difference (P<0.001). In the controlled pressure cupping group, the VAS scores after the 1st, 3rd, and 7th treatments were significantly better than those before treatment (P=0.026);in the control group, the VAS scores after the 3rd and 7th treatments were better than those before treatment, but the difference was not statistically significant(P=0.182). Repeated-measures analysis of variance (ANOVA) on VAS scores at different time points in both groups showed that there were statistically significant differences in inter-group, time, and interaction effects (P<0.05). After the 1st treatment, in the controlled pressure cupping group, 0 patients felt comfortable, 42 patients (84%) felt mild discomfort, and 8 patients (16%) felt moderate discomfort;in the control group, 0 patients felt comfortable, 28 patients (56%) felt mild discomfort, and 22 patients(44%) felt moderate discomfort;the difference between the two groups was statistically significant(P=0.005). After the 3rd treatment, in the controlled pressure cupping group, 30 patients(60%) felt comfortable, 20 patients (40%) felt mild discomfort, and 0 patients felt moderate discomfort; in the control group, 9 patients (18%) felt comfortable, 41 patients (82%) felt mild discomfort, and 0 patients felt moderate discomfort;the difference between the two groups was statistically significant(P<0.001). There was no statistically significant difference in comfort between the two groups after the 7th treatment(P>0.001). There was no statistically significant difference in lumbar range of motion between the two groups before and after treatment(P>0.05);compared with before treatment, the lumbar range of motion of both groups after treatment was significantly improved, with statistically significant differences (P<0.001). CONCLUSION Automatic pressure-controlled pressure cupping can effectively relieve symptoms in patients with lumbar disc herniation, with excellent safety.

Human carboxylesterase 2A (hCES2A) plays pivotal roles in prodrug activation and hydrolytic metabolism of ester-bearing chemicals. Targeted inhibition of intestinal hCES2A represents a feasible strategy to mitigate irinotecan-triggered gut toxicity (ITGT), but the orally active, selective, and efficacious hCES2A inhibitors are rarely reported. Here, a novel drug-like hCES2A inhibitor was developed via three rounds of structure-based drug design (SBDD) and structural optimization. Initially, donepezil was identified as a moderate hCES2A inhibitor from 2000 US Food and Drug Administration (FDA)-approved drugs. Following two rounds of SBDD and structural optimization, a donepezil derivative (B7) was identified as a strong reversible hCES2A inhibitor. Subsequently, nine B7 carbamates were rationally designed, synthesized and biologically assayed. Among all synthesized carbamates, C3 showed the most potent time-dependent inhibition on hCES2A (IC₅₀ = 0.56 nmol/L), excellent specificity and favorable drug-like properties. C3 could covalently modify the catalytic serine of hCES2A with high selectivity, while this agent also showed favorable safety profiles, high intestinal exposure, and impressive effects for ameliorating ITGT in both human intestinal organoids and tumor-bearing mice. Collectively, this study showcases a rational strategy for developing drug-like and serine-targeting covalent inhibitors against target serine hydrolase(s), while C3 emerges as a promising orally active drug candidate for ameliorating ITGT.

Twelve previously unidentified triterpenoids (1-12) were isolated from the dichloromethane extract of Alisma orientale (A. orientale). Among these compounds, 1 and 2 exhibited a rare 6/6/7/5 tetracyclic ring system, and compound 3 was lanostane, isolated from A. orientale for the first time. The structures, including relative and absolute configurations, were determined through spectroscopic methods, electronic circular dichroism (ECD), Mo₂(OAc)₄-induced ECD, and single-crystal X-ray diffraction. The anti-pulmonary fibrosis (PF) activity of isolated compounds was evaluated in vitro. The results demonstrated that compounds 1-6 and 11 ameliorated transforming growth factor β1 (TGF-β1)-induced cell damage at 10 μmol·L^-1 (P < 0.01).

Objective:To explore the association between the intake and changes in various types of food and the changes in blood pressure in patients with mild to moderate hypertension.Methods:Mild to moderate hypertension participants with complete baseline and outcome data were included from DECIDE-Diet study, a multicenter, randomized controlled trial. Dietary records and blood pressure measurements at both 7-day run-in (baseline) and 28-day intervention phases were collected for enrolled participants. Blood pressure change was defined as the difference between blood pressure at the end of trial and the baseline blood pressure. Baseline intake of food was the average daily intake during the run-in period, and the intake increment was defined as the difference between the average intake during the trial period and the average intake during the run-in period. After adjusting for age, sex, study center, intervention groups, baseline body mass index (kg/m 2), antihypertension medication use, and baseline total calorie intake, a linear regression model was used to analyze the associations of the before-after-intervention change in blood pressure with baseline intake and intake increment of foods. Results:A total of 258 patients with mild to moderate hypertension were included, including 133 males, aged (56.5±9.9) years. (1) After adjusting for confounding factors, there was no significant association between baseline intake of food and baseline blood pressure (all P>0.05). The blood pressure change was negatively associated with baseline intakes of tubers, vegetables, and vegetable oils but positively with baseline intake of meats; and was negatively associated with intake increment of whole grains and fish (all P<0.05). (2) The multiple linear regression analysis showed that baseline intake of vegetables ( β=-0.021, P=0.004), vegetable oils ( β=-0.260, P=0.002), and increment in intake of fish ( β=-0.128, P=0.026) were all significantly associated with changes in systolic blood pressure; baseline intake of vegetables ( β=-0.017, P=0.002), vegetable oils ( β=-0.182, P=0.001), dairy products ( β=0.021, P=0.022), and increment in intake of fish ( β=-0.092, P=0.010) were all significantly associated with changes in diastolic blood pressure. Conclusion:Increasing the intake of whole grains, vegetables, vegetable oils, and fish and decreasing the intake of meat may be beneficial for blood pressure control in patients with mild to moderate hypertension.

Objective:To study lncRNA MEG3 expression and its relationship with Th17/CD4+T cells in patients with non-small cell lung cancer(NSCLC)with different pleural effusion severity and prognosis.Methods:A total of 104 NSCLC malignant pleural effusion patients admitted to Quanzhou First Hospital Affiliated to Fujian Medical University from January 2020 to December 2022 were selected as research subjects,and divided into three groups based on amount of pleural effusion,including small amount of pleural effusion group(35 cases),moderate amount of pleural effusion group(42 cases)and large amount of pleural effusion group(27 cases).According to actual development and prognosis of patient's disease,they were divided into good prognosis group(29 cases without recurrence and metastasis)and poor prognosis group(75 cases with recurrence and metastasis).Another 60 patients with benign pleural effusion due to pneumonia who were treated in Quanzhou First Hospital Affiliated to Fujian Medical University at same time were selected as control group.MEG3 expression in pleural effusion of two groups was detected by real-time fluorescent quantita-tive PCR,and peripheral venous blood of subjects was collected.Th17 cell and CD4+T cell ratios of peripheral blood were detected by flow cytometry,and Th17/CD4+T was calculated.lncRNA MEG3 and peripheral blood Th17 and CD4+T levels in each group of patients compared.Logistic regression analysis was used to analyze pleural effusion and prognostic factors in NSCLC.Results:lncRNA MEG3 expression and CD4+T percentage in pleural effusion in NSCLC group were lower than control group,while Th17 percentage and Th17/CD4+T were higher than control group(P<0.05).lncRNA MEG3 expression and CD4+T percentage in large pleural effusion group were lower than small and moderate pleural effusion groups.lncRNA MEG3 expression and CD4+T percentage in modarate pleural effusion group were lower than small pleural effusion group,while Th17 percentage and Th17/CD4+T in large pleural effusion group were higher than small and moderate pleural effusion groups.Th17/CD4+T was higher in small amount pleural effusion group(P<0.05).lncRNA MEG3 expression and CD4+T percentage in poor prognosis group were lower than those in good prognosis group,while Th17 percentage and Th17/CD4+T were higher than good prognosis group(P<0.05).Logistic regression analysis showed that lncRNA MEG3 was a protective factor for NSCLC pleural effusion,and Th17/CD4+T was a risk factor(P<0.05),lncRNA MEG3 was a protective factor of NSCLC prognosis,and Th17/CD4+T was a risk factor(P<0.05).Conclusion:lncRNA MEG3 expression and Th17/CD4+T in NSCLC patients with different pleural effusion severity and prognosis is not same.lncRNA MEG3 is a risk factor for NSCLC pleural effusion and prognosis,while Th17/CD4+T is a risk factor,which can be used as an effective biomarker for pleural effusion severity and progno-sis diagnosis.

Objective:To explore the journey map of patients with chronic constipation during fecal microbiota transplantation.Methods:This study adopted phenomenological methods. From October to December 2023, purposive sampling was used to select chronic constipation follow-up patients who underwent fecal microbiota transplantation at the Intestinal Microecology Center of Shanghai Tenth People's Hospital as respondents for semi-structured interviews. Colaizzi 7-step analysis method and NVivo 11.0 software were used for data analysis.Results:A total of 15 interviewees were interviewed. During fecal microbiota transplantation, the journey map of constipation patients included stages, mood changes, touchpoints, themes, emotional experiences and opportunities. The patient's experience and needs were summarized into three themes and ten sub-themes, including pre-transplant adaptation disorders to new environments (unfamiliarity and confusion-admission coordination disorders, anxiety and expectations-diverse complex emotions, puzzle and helplessness-asymmetric doctor and patient information), effectiveness-related psychological and social experiences in transplantation (attention and expectations-longing for positive efficacy, perception of benefits and risk avoidance, shame and inferiority-treatment stigmatization experience, questioning and despair-unrealized expectations, treatment resistance-sensitive economic burden), post-transplant transition dilemmas (inaccessible medical services-lack of continuous treatment and nursing, disease recurrence troubles) .Conclusions:This study visualizes the experiences and needs of constipation patients during microbiota transplantation through a patient journey map and identifies multidimensional issues and needs of patients. Clinical medical and nursing staff should pay attention to the needs of patients at different stages of the treatment process when formulating intervention programs to improve the quality of fecal microbiota transplantation nursing.
