ObjectiveTo investigate the effects of Anmeidan (AMD) on neuroinflammation in the hippocampus of sleep-deprived rats. MethodsSD rats were randomly divided into four groups (n = 10 per group): control group, model group, AMD group, and melatonin group. A sleep deprivation model was established using the modified multiple platform water environment method. The AMD group received AMD at a dose of 18.18 g·kg-1·d-1, the melatonin group received melatonin at 100 mg·kg-1·d-1, and the control and model groups were given an equal volume of pure water. All treatments were administered by gavage for four weeks. Spontaneous activity was assessed using an animal behavior video system. Serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were measured by enzyme-linked immunosorbent assay (ELISA). Hippocampal pyramidal neuron morphology was examined using hematoxylin-eosin (HE) staining, and ultrastructural changes of hippocampal neurons were observed via transmission electron microscopy. Immunofluorescence was used to detect the expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in the hippocampus. Western blot analysis was performed to measure the expression of nuclear factor-κB (NF-κB), phosphorylated NF-κB (p-NF-κB), NOD-like receptor protein 3 (NLRP3), and Caspase-1 proteins. ResultsCompared with the control group, the model group showed a significant increase in activity duration and frequency (P<0.01), increased hippocampal pyramidal cell structural damage and decreased cell count, aggravated hippocampal ultrastructural damage, mitochondrial cristae disruption, and exacerbated vacuolization. The expression of p-NF-κB p65, NLRP3, and Caspase-1 proteins was upregulated, serum IL-1β, IL-6, and TNF-α levels were significantly elevated (P<0.01), and the fluorescence intensity of BDNF and NGF proteins was significantly reduced (P<0.01). Compared with the model group, the AMD group showed a significant reduction in activity duration and frequency (P<0.01), increased hippocampal pyramidal cell count with reduced structural damage, alleviated hippocampal ultrastructural damage, significantly downregulated p-NF-κB p65, NLRP3, and Caspase-1 protein expression (P<0.01), decreased serum IL-1β, IL-6, and TNF-α levels (P<0.01), and significantly increased the fluorescence intensity of BDNF and NGF proteins (P<0.01). ConclusionAnmeidan alleviates hippocampal neuronal damage in sleep-deprived rats, potentially by downregulating the NLRP3 signaling pathway, reducing inflammatory cytokine release, and increasing neurotrophic factor levels.

Guided by molecular networking, nine novel curvularin derivatives (1-9) and 16 known analogs (10-25) were isolated from the hydrothermal vent sediment fungus Penicillium sp. HL-50. Notably, compounds 5-7 represented a hybrid of curvularin and purine. The structures and absolute configurations of compounds 1-9 were elucidated via nuclear magnetic resonance (NMR) spectroscopy, X-ray diffraction, electronic circular dichroism (ECD) calculations, 13C NMR calculation, modified Mosher's method, and chemical derivatization. Investigation of anti-inflammatory activities revealed that compounds 7-9, 11, 12, 14, 15, and 18 exhibited significant suppressive effects against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in murine macrophage RAW264.7 cells, with IC50 values ranging from 0.44 to 4.40 μmol·L-1. Furthermore, these bioactive compounds were found to suppress the expression of inflammation-related proteins, including inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), NLR family pyrin domain-containing protein 3 (NLRP3), and nuclear factor kappa-B (NF-κB). Additional studies demonstrated that the novel compound 7 possessed potent anti-inflammatory activity by inhibiting the transcription of inflammation-related genes, downregulating the expression of inflammation-related proteins, and inhibiting the release of inflammatory cytokines, indicating its potential application in the treatment of inflammatory diseases.

This paper systematically combed and verified the name, origin, producing area, quality evaluation, harvesting, processing of Euryales Semen in famous classical formulas by consulting relevant ancient materia medica, medical books, prescription books and modern literature. The results showed that Euryales Semen was first collected by materia medica under the name of Jitoushi, and since the Ming dynasty, Qianshi has been used as a proper name and continues to this day, with other aliases such as Yanhuishi. Euryale ferox, a plant of the Nymphaeaceae family, is the same as that used in the past dynasties. However, due to long-term artificial domestication, the varieties vary with the origin, including Beiqian and Suqian. The medicinal part of Euryales Semen is mature seed kernel, its origin of ancient records mainly includes Shandong, Jiangsu, Henan and other places, since the Ming and Qing dynasties, Euryales Semen produced in Suzhou has been highly praised. Since modern times, it has gradually summarized and formed the best quality evaluation method of Euryales Semen with full grains, white cross-section, powdery enough and no broken powder. The harvesting time in the past dynasties was mainly August or in autumn. The main processing methods in the past dynasties included peeling for powder, pounding powder after steaming, drying and frying. Up to now, two mainstream processing methods of cleansing and stir-frying have been formed. Based on the research results, it is recommended that the mature seed kernel of E. ferox be used in famous classical formula Yihuangtang. Combined with the processing requirements of the original formula, it is suggested to refer to the stir-frying method in the general principles of processing of the current edition of Chinese Pharmacopoeia.

Objective:To evaluate the safety and efficacy of tumor-treating fields (TTFields) and chemoradiation in patients with high-grade glioblastoma.Methods:Clinical data of 38 patients admitted to the Jiangsu Cancer Hospital from September 2021 to May 2023 who were diagnosed with high-grade glioblastoma (36 cases of World Health Organization grade Ⅳ and 2 cases of grade Ⅲ) were retrospectively analyzed. All patients received TTFields combined with concurrent chemoradiation after surgery. Response assessment in neuro-oncology (RANO) criteria was used to evaluate the glioma responses as tumor remission, stable or progression. Common terminology criteria for adverse events v5.0 and TTFields related skin adverse reaction (dAE) criteria were used to evaluate the adverse events. Treatment compliance was assessed by data on the NovoTTF-200A therapeutic device, calculated as a percentage of daily TTFields usage time. Survival analysis was estimated by the Kaplan-Meier method and compared by the log-rank test.Results:The median duration of treatment with TTFields in 38 patients was 20 h (rang: 2.4-22.6 h), and the median treatment compliance was 83% (range: 10%-94%). After 42 days of TTFields combined with concurrent chemoradiation, 12 patients who underwent complete tumor resection were assessed as stable according to RANO criteria. Among the 26 patients who underwent partial tumor resection, 23 (88%) were evaluated as disease remission according to RANO criteria. The 7-, 10-, 13-month progression-free survival rate was 81.0%、64.0%、49.5%, repectively. The common adverse events included grade 1 (45%) and grade 2 (8%) dAE, without grade 3-4 dAE. Typical presentations included contact dermatitis, blisters, lesions or ulcers, and abscesses. The median follow-up time was 10.0 months (range: 1.6-21.3 months). At follow-up as of July 2023, 26 of the 38 patients were stable and 12 had disease progression (8 died).Conclusion:The preliminary results show that TTFields combined with chemoradiation is effective, safe and reliable treatment for high-grade glioblastoma.

A 28-year-old woman was found to have coagulation factor Ⅷ activity (FⅧ∶C) <1% and von Willebrand factor antigen (VWF∶Ag) <1% during routine prenatal examinations. No pathogenic variation was found in the exon region of the VWF gene using next-generation sequencing. The clinical presentation of this patient does not match the clinical characteristics of type Ⅲ hemophilia [von Willebrand disease (VWD) ]; therefore, third-generation sequencing technology was used to perform whole-genome sequencing on the patient and her family members. Multiple members of the patient’s paternal family carried a heterozygous variant of VPS33B, c.869G>C. The family members carrying this variant all had varying degrees of reduced VWF levels (39% -56% ). Moreover, the proband was detected with the heterozygous variant c.1474dupA in GP1BA. The ACMG and Clinvar databases determined that this variation was associated with platelet-type pseudo VWD. The decrease in VWF levels caused by heterozygous variations in VPS33B in families is the first international report, and no previous studies have reported cases of severe decrease in plasma VWF levels caused by double heterozygous variations in VPS33B and GP1BA.

As a basic source for the theoretical system of traditonal Chinese medicine (TCM), the Inner Canon of Yellow Emperor (《黄帝内经》) made the point of “treatment with combination of diverse methods and prescriptions”,which is one of the characteristics of TCM in treating diseases. This paper discussed the therapeutic idea of “diverse methods and prescriptions” from five dimensions, including time, population, regions, diseases, and treatments, and proposed that “combined treatment” is an effective measure to embody the idea of “diverse methods and prescriptions”. That is to say, by taking the combination of the concept of holism and syndrome differentiation and treatment as the starting point, combining pharmacological and non-pharmacological therapies, and treating both internal and external diseases through multiple ways and methods, the goal to treat the disease at the root, and keep yin at peace and yang compact can be achieved. Finally, it is suggested to guide the clinical practice with “treatment with combination of diverse methods and prescriptions”, providing new ideas for clinical diagnosis and treatment.

Objective:To investigate the current application of colonoscopy at hospitals in China.Methods:From November 2019 to January 2020, an online questionnaire survey was conducted among gastroenterologists and colonoscopists in hospitals of different levels. The contents of questionnaire survey included basic information of colonoscopy at the respondent′s hospital, protocols and patient education of bowel preparation, implementation of colonoscopy quality control, and colonoscopists′ understanding of polypectomy techniques and post-polypectomy follow-up.Results:A total of 236 valid questionnaires were collected, involving 187 hospitals, and 143 (76.5%) had an annual operation capacity of more than 5 000 cases. In terms of bowel preparation, split-dosed polyethylene glycol electrolyte powder (PEG) was the most commonly used (60.4%, 113/187) and the most common volume of PEG was 3 L (67.4%, 126/187). Verbal (90.9%, 170/187) and written (79.7%, 149/187) instructions were given more often than other methods for patient education of bowel preparation. Antifoaming agent was routinely used in 124 (66.3%) hospitals. In terms of quality control, only 11.5% (20/174) hospitals implemented all four measures. In terms of polypectomy techniques, 98.1% (203/207) colonoscopists chose hot snare polypectomy or endoscopic mucosal resection for lesions of diameter>1 cm, while options varied for lesions of diameter<1 cm. The interval of follow-up after polypectomy recommended by colonoscopists was shorter than that by guidelines.Conclusion:Several problems are found in the survey in the application of colonoscopy in China, i. e., patient education of bowel preparation is not diversified; quality control of colonoscopy still needs to be strengthened; polypectomy techniques and follow-up after polypectomy need to be further standardized.
