With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Headache is a common clinical complication of ischemic stroke. As a precursor of stroke, headache occurs repeatedly in the convalescent period of ischemic stroke, leading to secondary stroke and seriously hindering patients' rehabilitation. Currently, it is believed that the pathogenesis of ischemic stroke-related headache is associated with the abnormal release of vasoactive substances, high platelet aggregation, and stimulation of intracranial pain-sensitive structures. The active ingredients in traditional Chinese medicines(TCM) with the effects of activating blood to resolve stasis and clearing heat to release exterior can protect brain tissue and relieve headache by reducing the release of inflammatory cytokines, alleviating antioxidant stress, inhibiting neuronal apoptosis and so on. This paper introduces the research progress in the potential mechanism and TCM treatment of ischemic stroke-related headache, aiming to provide reference for further research and drug development of this complication.

Arbuscular mycorrhizal fungi provided is beneficial to Salvia miltiorrhiza for increasing yield, promoting the accumulation of active ingredients, and alleviating S. miltiorrhiza disease etc. However, the application of fungicides will affect the benefit of arbuscular mycorrhizal fungi and there is little research about it. This article study the effect of four different fungicides: carbendazim, polyoxin, methyl mopazine, and mancozeb on mycorrhiza benefit to S. miltiorrhiza by the infection intensity of arbuscular mycorrhizal fungi, the growth of S. miltiorrhiza, and the content of active ingredients. RESULTS:: showed that different fungicides had different effects. The application of mancozeb had the strongest inhibitory effect on the mycorrhizal benefit to S. miltiorrhiza. Mancozeb significantly reduced the mycorrhizal colonization and the beneficial effect of arbuscular mycorrhizal fungi on the growth and the accumulation of active components of S. miltiorrhiza. The application of polyoxin had no significant effect on mycorrhizal colonization. Instead, it had a synergistic effect with the mycorrhizal benefit to promoting the growth and accumulation of rosmarinic acid of S. miltiorrhiza. The inhibitory strengths of four fungicides are: mancozeb>thiophanate methyl, carbendazim>polyoxin. Therefore, we recommend applying biological fungicides polyoxin and avoid applying chemical fungicides mancozeb for disease control during mycorrhizal cultivation of S. miltiorrhiza.

Objective:To investigate the application effect of reverse abdominal wall advancement flap in repairing chest wall soft tissue defect after breast tumor resection.Methods:From October 2020 to April 2021, the Department of Plastic Surgery and Breast Surgery of Hainan Cancer Hospital cooperated to repair the chest wall wounds of 4 female patients with unilateral giant breast tumors after primary lesion resection. Patients aged 40-63 years old, with an average of 51.5 years old. The size of the tumor estimated by physical examination was 7 cm × 6 cm-15 cm × 20 cm. The flaps were closely monitored after surgery, and complications were recorded. Local recurrence was followed-up.Results:The wound size of 4 patients after mastectomy was 16 cm×14 cm-20 cm×18 cm. Abdomen separation range reached anterior axillary line laterally and contralateral clavicle midline medially. Inferiorly, 1 case reached umbilical level, 1 case reached 2 cm below the umbilicus, and 2 cases reached 3 cm below the umbilicus. Three cases were diagnosed as breast lobulated tumors, and 1 case invasive lobular carcinoma. Among the 4 cases, 3 flaps survived completely and healed by first intention, while another flap healed under blister scab. There was no necrosis, infection, hematoma, seroma, or vascular crisis of the flap. All patients were satisfied. Three patients received radiotherapy and one received radiotherapy combined with oral chemotherapy. All patients were followed up for 3-6 months. No local recurrence was discovered. The abdomen was tighter than before operation, but no stiffness was found. There was no abdominal pain, abdominal wall bulging or abdominal hernia.Conclusions:Reverse abdominal wall advancedment flap was used to repair soft tissue defect of the chest wall after breast tumor resection. The operation was simple and fast, with no need for additional donor site incision. Quick recovery allowed shorter interval between surgery and next scheduled treatments.

Objective:To investigate the preliminary effects of sub-pectoral fascial breast augmentation and reconstruction.Methods:Six patients (10 breasts) of mammary dysplasia, mastatrophy, prophylactic mastectomy, unilateral breast defect with contralateral mastatrophy were included in the study from Oct. 2019 to July 2021. The mean patient age was 29 years (range, 20 to 35 years). All the textured and smooth cohesive gel implants were inserted under pectoralis major fascia by endoscopic-assisted, incisions were including axillary, around areola and inferior mammary fold approaches. The prophylactic mastectomy cases were performed nipple sparing mastectomy and sub-pectoral fascial breast restoration with implants. The fat and fascia tissue were well reserved to give a satisfying coverage of the appropriate implant. Negative pressure drainage and moulding dressing were used after the surgery.Results:Ten breast augmentation and restoration with a mean implant size of 200 cc (range, 180-300 cc). Less immediate postoperative pain and bleeding were reported. Patients were followed up for an average of 10 months (range, 6 to 21 months). There were no cases of major malpositions, double-bubble and bottom out symptoms. The overall outcome was with better symmetry and satisfaction with time passed by, and no secondary surgical procedures needed.Conclusions:Primary and satisfactory results have been obtained in subfascial breast augmentation and restoration for indications. With the endoscopic-assisted accurate pectoral fascial dissection, and well reserved soft tissue coverage, this technique could avoid the pectoralis major muscle ablation and keep the advantages of sub-glandular plane.
