ObjectiveTo explore the listed varieties and prescription characteristics of Chinese patent medicines for stroke in China， explore the medication rules of Chinese medicine for stroke， and provide guidance for further clinical research and development of Chinese patent medicines. MethodsExcel 2021 and the Ancient and Modern Medical Record Cloud Platform （V2.3.5） were used to systematically mine and analyze the varieties and prescriptions of Chinese patent medicines for stroke in China. ResultsA total of 244 Chinese patent medicines （two for different dosage forms of the same prescription）， 1 736 approval documents for Chinese patent medicines， 792 manufacturers， and 83 varieties of protected Chinese patent medicines were finally included in the database. The top three dosage forms were capsules （75）， pills （53）， and tablets （42）. There were 28 Chinese patent medicines for stroke in the National Essential Drug Catalogue （2018）， 129 in the National Essential Medical Insurance， Industrial Injury Insurance and Maternity Insurance Drug Catalogue （2023）， and 4 in the National Non-prescription Drug Catalogue. Among the 138 prescriptions screened out， Chinese patent medicines mainly treated stroke patients with the syndrome of Qi deficiency and blood stasis. The top three most frequent medicinal herbs were Chuanxiong Rhizoma （63）， Pheretima （47）， and Salviae Miltiorrhizae Radix et Rhizoma （47）. The medicinal herbs used were mainly warm， pungent， with the meridian tropism to the liver meridian. The correlation analysis showed that the herb pair with the highest support was Astragali Radix-Chuanxiong Rhizoma， and that with the highest confidence was Carthami Flos-Chuanxiong Rhizoma. Five herb combinations were identified based on the cluster analysis. ConclusionThe Chinese patent medicines for stroke mainly treat patients with the syndrome of Qi deficiency and blood stasis. The medicinal herbs used in the prescriptions mainly have the functions of activating blood and resolving stasis， extinguishing wind and stopping convulsions. Drug compatibility usually focuses on activating blood and resolving stasis， as well as expelling phlegm and opening orifices. This review of the varieties and prescription characteristics of Chinese patent medicines for stroke helps optimize clinical decision-making， guide drug research and development， promote medical research and scientific progress， and provide more effective support and guarantee for the treatment of stroke patients.

ObjectiveTo explore the effects of Renshentang on atherosclerosis （AS） in mice based on the role of transient receptor potential vanilloid1 （TRPV1） in regulating cholesterol metabolism in foam cells. MethodsNine SPF-grade 8-week-old C57BL/6J mice were set as a normal group， and 60 ApoE^-/- mice were randomized into model， positive drug （simvastatin， 0.02 g·kg^-1·d^-1）， and low-， medium-， and high-dose （1.77， 3.54， 7.08 g·kg^-1·d^-1， respectively） Renshentang groups （n=12） according to body weight. The normal group was fed with a normal diet， and the other groups were fed with a high-fat diet and given corresponding drugs by oral gavage for the modeling of AS. The mice were administrated with corresponding drugs once a day for 12 weeks. After the last administration and fasting for 12 h， the aorta was collected. Plaque conditions， pathological changes， levels of total cholesterol （TC）， triglcerides （TG）， low-density lipoprotein-cholesterol （LDL-C）， and high-density lipoprotein-cholesterol （HDL-C）， and the expression of TRPV1， liver X receptor （LXR）， inducible degrader of the low-density lipoprotein receptor （IDOL）， and low-density lipoprotein receptor （LDLR） in the aortic tissue were observed and detected by gross oil red O staining， HE staining， Western blot， immunohistochemistry， and real-time PCR. ResultsCompared with the normal group， the model group presented obvious plaque deposition in the aorta， raised levels of TC， TG， and LDL-C in the serum （P<0.01）， up-regulated expression level of LDLR in the aorta （P<0.01）， lowered level of HDL-C in the serum， and down-regulated expression levels of TRPV1， LXR， and IDOL in the aorta （P<0.05， P<0.01）. Compared with the model group， the positive drug and Renshentang at different doses alleviated AS， elevated the levels of HDL-C， TRPV1， LXR， and IDOL （P<0.05， P<0.01）， while lowering the levels of TC， TG， LDL-C， and LDLR （P<0.05， P<0.01）. ConclusionRenshentang has a lipid-lowering effect on AS mice. It can effectively reduce lipid deposition， lipid levels， and plaque area of AS mice by activating TRPV1 expression and regulating the LXR/IDOL/LDLR pathway.

Epigenomic imbalance drives abnormal transcriptional processes,promoting the onset and progression of cancer.Although defective gene regulation generally affects carcinogenesis and tumor suppression networks,tumor immunogenicity and immune cells involved in antitumor responses may also be affected by epigenomic changes,which may have significant implications for the development and application of epigenetic therapy,cancer immunotherapy,and their combinations.Herein,we focus on the impact of epigenetic regulation on tumor immune cell function and the role of key abnormal epigenetic processes,DNA methylation,histone post-translational modification,and chromatin structure in tumor immunogenicity,and introduce these epigenetic research methods.We emphasize the value of small-molecule inhibitors of epigenetic modulators in enhancing antitumor immune responses and discuss the challenges of developing treatment plans that combine epigenetic therapy and immuno-therapy through the complex interaction between cancer epigenetics and cancer immunology.

ObjectiveTo investigate the mechanism and effect of Qingfei Paidu decoction on transient receptor potential vanilloid-1/Transient receptor potential ankyrin1 （TRPV1/TRPA1） based on heat-sensitive channel and inflammatory response. MethodAccording to body weight， 80 8-week-old C57BL/6 mice were randomly divided into the normal group， model group， dexamethasone group （5 mg·kg^-1）， and low-dose， medium-dose， and high-dose groups of Qingfei Paidu decoction （14.865， 29.73， 59.46 g·kg^-1）， with 12 mice in each group. In addition to the normal group， the other groups were administered 20 μL （1×10^-3 g·kg^-1） to each mouse by airway infusion to establish the acute lung injury （ALI） model. In the administration group， the drug was given 1 h after modeling and again after an interval of 24 h. The lung tissue was taken 36 h after modeling. Double lung wet/dry weight ratio（W/D）， hematoxylin-eosin （HE） staining， enzyme-linked immunosorbent assay （ELISA）， and Western blot were used to observe and detect the pathological changes of lung tissue， expression levels of inflammatory cytokine tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）， and expressions of TRPV1 and TRPA1 proteins in heat-sensitive channel， nuclear factor kappa-B （NF-κB）， inhibitor of NF-κB （IκBα） in inflammatory pathway， and phosphorylated proteins. The phosphorylated protein/total protein ratio was calculated. ResultCompared with that in the normal group， the lung tissue of mice in the model group was seriously damaged， and pulmonary capillary permeability increased. Alveolar capillary congestion and dilation destroyed the complete structure of the alveolar， and the alveolar wall thickened. A large number of inflammatory cells and red blood cells were infiltrated， and pulmonary edema was significantly aggravated. The expressions of TNF-α， IL-6， TRPV1， TRPA1， phosphorylated NF-κB p65/NF-κB p65， and phosphorylated IκBα/IκBα were significantly increased （P<0.01）， and the whole lung W/D was significantly increased （P<0.01）. Compared with the model group， the dexamethasone group and low-dose， medium-dose， and high-dose groups of Qingfei Paidu decoction could significantly improve pulmonary edema. TNF-α， IL-6， TRPV1， TRPA1， lung tissue NF-κB p65， and IκBα phosphorylated protein/total protein ratio decreased significantly （P<0.05， P<0.01）. The whole lung W/D also decreased significantly （P<0.05， P<0.01）. ConclusionQingfei Paidu decoction has anti-inflammatory and protective effects on LPS-ALI mice， which can effectively reduce inflammation， induce diuresis， and alleviate edema. Its mechanism may be related to the regulation of the expression of TRPA1 and TRPV1 and the inhibition of the activation of the NF-κB pathway.

Objective:To investigate the feasibility and clinical efficacy of posterior vertebral column resection (PVCR) combined with polymethylmethacrylate-augmented pedicle screw instrumentation and shortening of spinal column for stage Ⅲ Kümmell's disease with very severe collapse of fractured vertebra.Methods:From January 2017 to September 2021, 9 patients with stage Ⅲ Kümmell's disease with very severe collapse of fractured vertebra underwent PVCR combined with polymethylmethacrylate-augmented pedicle screw instrumentation and shortening of spinal column. Their medical records were retrospectively analyzed. There were 1 male and 8 females, aged (66.9±5.8) years. The injured vertebra was located at T 11 in 2 patients, at T 12 in 4, at L 1 in 2 and at L 2 in 1. X-ray, CT and MRI were performed before operation. The posterior intervertebral heights of adjacent vertebral bodies of the fractured vertebra in the median sagittal position were measured on CT or MRI to evaluate the shortening of the spinal column before PVCR. Recorded were intraoperative bleeding volume, operation time, complications, bone graft fusion, and American Spinal Injury Association (ASIA) grading at preoperation and the last follow-up. The visual analogue scale (VAS) pain scores, Oswestry disability index (ODI) scores, and kyphotic cobb angles at preoperation, 1 week and 3 months postoperation, and the last follow-up were compared to evaluate the clinical efficacy of PVCR. Results:All patients underwent surgery successfully, with tight closure of adjacent vertebrae after resection of the injured vertebra and bone grafting. Operation time was (240.6±23.2) min and intraoperative bleeding (505.6±95.0) mL. The 9 patients were followed up for (17.3±5.6) months. No worsening symptoms of nerve injury, cerebrospinal fluid leakage, or other serious complications were found after operation, nor such complications as loosening or breakage of internal fixation or adjacent vertebral fractures. Bone fusion was achieved at the bone graft sites in all patients by the last follow-up. The VAS and ODI scores and cobb angles at 1 week and 3 months postoperation and at the last follow-up were significantly decreased compared with preoperation ( P<0.05). There were no significant differences in VAS scores or cobb angles among postoperative 1 week and 3 months and the last follow-up ( P>0.05), but pairwise comparisons between different time points after operation showed significant differences in ODI, with postoperative 1 week > postoperative 3 months > the last follow-up ( P<0.05). The ASIA grading at the last follow-up was improved from preoperative grade C to grade D in 2 cases, from preoperative grade C to grade E in 1 case and from preoperative grade D to grade E in 5 cases. Conclusion:PVCR combined with polymethylmethacrylate-augmented pedicle screw instrumentation and shortening of spinal column is a feasible and effective surgical treatment for stage Ⅲ Kümmell's disease with very severe collapse of fractured vertebra, leading to good clinical efficacy.

The genomic DNA of Rubus rosaefolius was extracted and sequenced by Illumina NovaSeq platform to obtain the complete chloroplast genome sequence, and the sequence characteristics and phylogenetic analysis of chloroplast genes were carried out. The results showed that the complete chloroplast genome of the R. rosaefolius was 155 650 bp in length and had a typical tetrad structure, including two reverse repeats (25 748 bp each), a large copy region (85 443 bp) and a small copy region (18 711 bp). A total of 131 genes were identified in the whole genome of R. rosaefolius chloroplast, including 86 protein coding genes, 37 tRNA genes and 8 rRNA genes. The GC content of the whole genome was 36.9%. The genome of R. rosaefolius chloroplast contains 47 scattered repeats and 72 simple sequence repeating (SSR) loci. The codon preference is leucine codon, and the codon at the end of A/U is preferred. Phylogenetic analysis showed that R. rosaefolius had the closest relationship with R. taiwanicola, followed by R. rubraangustifolius and R. glandulosopunctatus. The chloroplast genome characteristics and phylogenetic analysis of R. rosaefolius provide a theoretical basis for its genetic diversity research and chloroplast development and utilization.

One hundred and forty-five patients with primary aldosteronism (PA) admitted from 2006 to 2013 were enrolled in the study. The diagnosis of PA was confirmed by upright furosemide test and all patients met the following criteria: ① round-or oval-shaped lesion of low density with diameter>1 cm in one adrenal gland shown in contrast CT scan; ② no lesion or abnormality in contralateral adrenal gland; ③serum potassium level<3.5 mmol/L. Of 145 patients, 106 underwent total adrenalectomy, 36 partial adrenalectomy and 3 tumor enucleation. Serum potassium was (2.75±0.55) mmol/L before and (4.03±0.46) after surgery. Potassium was normalized after treatment in 141 cases (97.2％) with correction or improvement in hypertension; 4 patients (2.8％) remained hypokalemic and received spironolactone. Patients with normalized potassium were followed up for a medium period of 74 months (22—103 months), of whom 32 (22.7％) dropped off; the remaining 109 (77.3％) patients did not have hypokalemia. Multivariate linear correlation analysis showed that serum potassium level was negatively correlated with tumor diameter (r=?0.273,95％ CI:?0.086—?0.564, P=0.026) and basal serum aldosterone level (r=?0.261,95％ CI:?0.047— ?0.514, P=0.036). In PA patients with unilateral adrenal macroadenoma and hypokalemia, satisfactory surgical resolution can be achieved without adrenal venous sampling in majority of patients.

Tumor cells along with a small proportion of cancer stem cells exist in a stromal microenvironment consisting of vasculature, cancer-associated fibroblasts, immune cells and extracellular components. Recent epidemiological and clinical studies strongly support that vitamin D supplementation is associated with reduced cancer risk and favorable prognosis. Experimental results suggest that vitamin D not only suppresses cancer cells, but also regulates tumor microenvironment to facilitate tumor repression. In this review, we have outlined the current knowledge on epidemiological studies and clinical trials of vitamin D. Notably, we summarized and discussed the anticancer action of vitamin D in cancer cells, cancer stem cells and stroma cells in tumor microenvironment, providing a better understanding of the role of vitamin D in cancer. We presently re-propose vitamin D to be a novel and economical anticancer agent.

OBJECTIVE: To study the clinical phenotype and gene mutation analysis of a hereditary abnormal fibrinogenemia family and explore its molecular pathogenesis. METHODS: The STA-R automatic hemagglutination analyzer to detect the proband and its family members (3 generations of 5 people) of prothrombin time(PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen activity (Fg: C), D-dimer (D-D), fibrinogen and fibrin degradation products (FDPs), plasminogen activity (PLG: A); The plasma levels of Fg: C and fibrinogen (Fg: Ag) were measured by Clauss method and immunoturbidimetry respectively. All exons and flanking sequences of FGA, FGB and FGG genes of fibrinogen were amplified by PCR, and the PCR products were purified and sequenced for gene analysis. The model was analyzed by Swiss software. RESULTS: The PT and APTT of the proband, her mother and sister were slightly prolonged, TT was significantly extend, Fg: C decreased significantly, Fg: Ag, PLG: A, D-D and FDPs are within the normal range; Her brother and daughter of the results are normal. Genetic analysis showed that g.7476 G>A heterozygous missense mutation in exon 8 of FGG gene resulted in mutations in arginine at position 275 of fibrinogen gamma D domain to histidine (Arg275His). Her mother and sister have the same Arg275His heterozygous mutation, brother and daughter for the normal wild type. CONCLUSION The heterozygous missense mutation of FGG gene Arg275His in patients with hereditary dysfibrinogenemia is associated with a decrease in plasma fibrinogen activity.
