ObjectiveTo observe the clinical efficacy and safety of Chinese medicinal mixture for dispelling stasis and resolving phlegm combined with western medicine in the treatment of epilepsy combined with cognitive impairment by randomized， double-blind， placebo-controlled， parallel-group trial. MethodA total of 123 inpatients and outpatients with epilepsy complicated with cognitive impairment admitted to the department of neurology at Longhua Hospital from October 2020 to October 2021 were randomly assigned into a control group （62 cases， carbamazepine + placebo） and a treatment group （61 cases， carbamazepine + Quyu Dingxian Zhengtong mixture） by random number table method. In the treatment group， 4 cases were exfoliated and eliminated. In the control group， 3 cases fell off. Finally， 57 cases in the treatment group and 59 cases in the control group were included. The total course of treatment for both groups was 12 weeks. The clinical efficacy， efficacy for traditional Chinese medicine （TCM） syndromes， and incidence of adverse reactions were compared between two groups. The changes of seizure frequency， abnormal rate of electroencephalogram （EEG）， cognitive function score， serum homocysteine （HCY）， folic acid， and vitamin B₁₂ （B₁₂） were measured and compared before and after treatment. ResultAfter 12 weeks of treatment， the treatment group had higher clinical efficacy ［92.98% （53/57） vs 79.66% （47/59）， χ²=4.327， P<0.05］ and efficacy for TCM syndromes ［96.49% （55/57） vs 84.75% （50/59）， χ²=4.660， P<0.05］ than the control group. The treatment group was superior to the control group in reducing the seizure frequency （Z=-3.938， P<0.01） and improving the Montreal cognitive assessment （MoCA） score （t=4.333， P<0.01） and mini-mental state examination （MMSE） score （t=9.531， P<0.01）. The variations in serum HCY， folic acid， and B₁₂ in the treatment group were less than those in the control group （t=-7.233， t=-7.972， t=-6.871， P<0.01）. After treatment， the abnormal rate of EEG in the treatment group was lower than that in the control group （χ²=4.437， P<0.05）. The incidence of adverse reactions in the treatment group （1.75%， 1/57） was lower than that （13.56%， 8/59） in the control group （corrected χ²=4.116， P<0.05）. ConclusionChinese medicinal mixture for dispelling stasis and resolving phlegm in combination with western medicine had better efficacy and safety than western medicine alone in the treatment of epilepsy complicated with cognitive impairment. Specifically， the combination outperformed western medicine alone in terms of clinical efficacy， efficacy for TCM syndromes， reduction in seizure frequency， abnormal rate of EEG， adverse reactions， improvement of cognitive function， and variations in serum folic acid， B₁₂， and HCY values. Chinese medicinal mixture for dispelling stasis and resolving phlegm may improve the clinical efficacy and safety by changing the metabolism of folic acid， B₁₂， and HCY in serum of the patients with epilepsy complicated with cognitive impairment.

Abstract: Total RNA was isolated from Siraitia grosvenorii fruit by the method of modified Trizol, according to S. grosvenorii fruit characteristics of rich phenols, polysaccharide, oil and proteins. The OD260/280, OD260/230, RNA integrity (RIN) and yield of the total RNA with this method were 2.01, 2.02, 9.50 and 260 mirog.g-1, respectively. The open reading frame (ORF) of dehydroascorbate reductase (DHAR), named as SgDHAR, was cloned by rapid amplification of cDNA ends (RACE) and RT-PCR method from S. grosvenorii. The GenBank accession number for this gene is KC907731. The SgDHAR gene contains a full-length cDNA of 1,252 bp including ORF of 819 bp and encodes a predicted protein of 272 amino acids. The molecular mass is 30.217 7 kD and the isoelectric point is 8.76. Homology comparison showed that it shared 87% nucleotide sequence homology with Cucumis sativus. Expression patterns using qRT-PCR analysis showed that SgDHAR was mainly expressed in fruit and stem, followed by flower, and was lowest in root, while the expression level was 6.83 times in triploid. T than that in diploid. Therefore, SgDHAR gene may be involved in abortion of triploid seedless S. grosvenorii.

Objective:To explore the mechanism of the prescription consisting Aconiti Lateralis Radix Praeparata and Epimedii Folium in the treatment of chronic heart failure （CHF） based on network pharmacology，followed by verification in H9c2 myocardial cells with hypoxia-reoxygenation injury in vitro and in zebrafish with vascular endothelial growth factor receptor （VEGFR） tyrosine kinase inhibitor Ⅱ （VRI） -induced vascular insufficiency. Method:The active ingredients in Aconiti Lateralis Radix Praeparata and Epimedii Folium were searched from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP），the corresponding target genes from the Universal Protein Resource （UniProt）， and the CHF-related targets from Online Mendelian Inheritance in Man （OMIM） and GeneCards. Both the active ingredient-potential target network and the active ingredient-CHF-related target network were generated using Cytoscape 3.6.1， followed by the protein-protein interaction （PPI） network construction and Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genome （KEGG） enrichment analysis based on MetaScape. H9c2 myocardial cells exposed to hypoxia-reoxygenation were selected for determining the proliferation-promoting effect by methyl thiazolyl tetrazolium （MTT） assay. The protein expression of B-cell lymphoma-2（Bcl-2）， Bcl-2-associated X protein（Bax），cysteinyl aspartate-specific protease-3（Caspase-3）， protein kinase B（PKB/Akt），phosphorylated protein kinase B（p-Akt），phosphorylated extracellular signal-regulated kinases 1/2 （p-ERK1/2），extracellular signal-regulated kinase 1/2 （ERK1/2）， and poly adenosine diphosphate ribose polymerase（PARP）was detected by Western blotting. The efficacy of the prescription in promoting angiogenesis was verified in a zebrafish model of VRI-induced vascular injury. Result:There were 28 active ingredients for the prescription， 209 corresponding targets， 1 296 CHF-related targets， and 94 common gene targets shared by the prescription and CHF. PPI network clustering suggested that Aconiti Lateralis Radix Praeparata and Epimedii Folium alleviated CHF by interfering with cell differentiation and metabolism and angiogenesis. GO analysis revealed that CHF relief was achieved via the intervention in such biological processes as cell migration，vascular development， and angiogenesis. Pharmacodynamic experiments verified that Epimedii Folium （10 mg·L^-1） alone and the prescription （10 mg·L^-1）both enhanced the proliferation of H9c2 myocardial cells under the hypoxia-reoxygenation condition （P<0.05），while the latter also increased the expression of Bcl-2，Bcl-2/Bax， and PARP （P<0.05） and reduced the expression of Caspase-3， Akt， and ERK （P<0.05）. The prescription at the concentrations of 0.3 and 0.1 g·L^-1 promoted angiogenesis （P<0.05）. Conclusion:Aconiti Lateralis Radix Praeparata and Epimedii Folium exert the therapeutic effect against CHF via multiple ingredients，multiple targets， and multiple channels. Such combination promotes the proliferation of H9c2 myocardial cells under hypoxic condition and protects zebrafish from vascular injury by up-regulating the expression of Bcl-2 and PARP，increasing Bcl-2/Bax ratio，and down-regulating the expression of Caspase-3，Akt， and ERK.

Objective This study aims to establish a non-puerperal mastitis (NPM) rat model by simulating hyperprolactinemia and immune-inflammatory states, and to evaluate its local inflammatory characteristics in the mammary gland, thereby laying the foundation for research on the diagnosis and treatment of this clinically challenging disease. Methods Twelve SPF-grade Wistar female rats were evenly divided into a control group and a model group. During the experiment, the control group received no experimental treatment or medication. The model group received daily subcutaneous injections of 100 mg/kg metoclopramide hydrochloride for 7 consecutive days. Serum prolactin (PRL) levels were measured using ELISA on the 10th, 20th, and 30th days after the first injection. After 7 days of injections, 200 μL of lactating SD rat milk was mixed with 200 μL of complete Freund's adjuvant to prepare an oil-in-water emulsion, which was administered by multiple subcutaneous injections into the back of the Wistar rats for the initial immunization. Seven days after the initial immunization, the emulsion was injected subcutaneously into the third, fourth, and fifth mammary glands for the final immunization. After the final immunization, the rats were observed for 28 days for changes in mammary gland appearance, and the size of mammary nodules was calculated. On the 3rd, 7th, 14th, and 28th days, hematoxylin-eosin (HE) staining was used to analyze mammary tissue morphology. Immunohistochemistry was employed to detect CD138 expression levels. ELISA was used to measure the levels of interleukin (IL)-6, IL-1β, tumor necrosis factor (TNF)-α, and inducible nitric oxide synthase (iNOS) in mammary tissue to comprehensively assess the model. Results Rats in the model group exhibited mammary skin ulceration and foul odor at the ulcer sites. Palpation and ultrasound revealed the formation of mammary nodules. HE staining showed that on the 3rd day after the final immunization, normal ductal and lobular structures in the mammary glands disappeared, with significant infiltration of plasma cells. On the 7th day, ductal dilation, epithelial necrosis and detachment, and pronounced periductal plasma cell and lymphocyte (predominantly T-lymphocytes) infiltration were observed. On the 14th day, there was a proliferation of fibrofatty tissue, small blood vessels, and granulation tissue, with scattered plasma cells in the interstitium. By the 28th day, inflammatory cell infiltration and fibrous tissue proliferation were reduced, with granuloma formation. Serum PRL levels in the model group were significantly increased on the 10th day (P<0.05) and the 20th day (P<0.001). IL-6 and TNF-α levels in mammary tissue were higher in the model group compared to the control group on the 3rd, 7th, 14th, and 28th days (P<0.05). IL-1β levels were higher on the 3rd, 7th, and 14th days compared with the control group (P<0.01) but lower than the control group on the 28th day (P>0.05). iNOS levels were significantly higher on the 7th day after the final immunization (P<0.001). Conclusion A successful NPM model was established in rats, which exhibited typical pathological features such as local mammary masses, abscesses, ulcers, ductal dilation and plasma cell infiltration. This model can serve as a foundation for further research into the diagnosis and treatment of this clinically challenging disease.

MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 108 patients with liver meridian heat accumulation type acne mastitis in the nodular stage were randomly assigned to a treatment group and a control group， with 54 patients in each group. Both groups received topical application of JO once daily at a thickness of 3~5 mm for 8 hours， along with standard nursing care. On this basis， the treatment group received oral CXD granules， while the control group received placebo granules， administered twice daily， 3 sachets per dose， for 14 consecutive days. Clinical efficacy， TCM symptom scores， nodule size， visual analogue scale （VAS） pain scores， white blood cell （WBC） count， C-reactive protein （CRP） level， and systemic immune-inflammation index （SII） were compared. At the end of treatment， efficacy and safety indicators were evaluated. A 6-month follow-up was conducted to compare the proportion of patients undergoing surgical treatment. ResultsThe total clinical efficacy rate in the treatment group was 90.38% （47/52）， significantly higher than 32.00% （16/50） in the control group （P＜0.01）. The treatment group also showed significantly lower TCM symptom scores， VAS scores， nodule size， WBC count， CRP level， and SII （P＜0.05 or P＜0.01）. During follow-up， the surgical intervention rate in the treatment group was 5.77% （3/52）， lower than 14.00% （7/50） in the control group， with a statistically significant difference （P＜0.01）. No significant abnormalities were observed in safety indicators before and after treatment in either group. ConclusionCXD effectively reduces nodule size and alleviates symptoms such as redness and pain in patients with acne mastitis of liver meridian heat accumulation type， improves TCM symptom scores， enhances overall clinical efficacy， and demonstrates good safety.

The treatment of spinal cord injury is always a stubborn problem for neurosurgeons because nerve cell cannot regenerate and the glia scar can prevent the axonal regeneration. Olfactory ensheathing cells (OECs) is a kind of especial glia cell, which possesses the character of horizontal cell of central nervous system and schwann cell. Many foundational and clinical studies showed that the olfactory ensheathing cellscan promote axonal regeneration and prove axonal growth, some progress is made and this is bringing hope for treatment of spine injury.

BACKGROUND: To illustrate the research framework, overall knowledge structure, and development trends of Chinese medicine (CM) treatment for osteosarcoma (OS) by using a bibliometric analysis and newly developed visualization tools. METHODS: Research datasets were acquired from the Web of Science (WOS) database from January 1, 1980 to September 30, 2019. VOS viewer and Citespace software was used to analyze the data and generate visualization knowledge maps. Annual trends of publications, distribution of institutes, distribution of journals, citation and H-index status, co-authorship status, research hotspots and co-citation status were analyzed. RESULTS: A total of 223 publications in the WOS database met the requirement. The number of published articles showed a rise but the citation frequency and the H-index of China were relatively low. The cooperation between the countries, institutes and authors were relatively weak. Most publications were basic researches. Most of the previous researches focused on basic mechanisms of CM in treating OS, and therapy and improvement of dosage form may become a frontier in this research field. CONCLUSIONS Compared with other fields, the field of CM treatment for osteosarcome is still in infancy. The distribution of researches is imbalanced and cooperation between countries, institutions and authors remains to be strengthened. Furthermore, basic research occupies an absolute dominant position, and the exploration of the molecular mechanism of CM in preventing and treating OS may become a key point in the future.

Trastuzumab has improved survival rates in human epidermal growth factor receptor 2(HER2)-positive breast cancer(BC),but drug resistance leads to treatment failure.Natural killer(NK)cell-mediated antibody-dependent cell cytotoxicity(ADCC)represents an essential antitumor immune mechanism of trastuzumab.Traditional Chinese medicine(TCM)has been used for centuries to treat diseases because of its capacity to improve immune responses.Xianling Lianxia formula(XLLXF),based on the principle of"strengthening body and eliminating toxin",exhibits a synergistic effect in the trastuzumab treatment of patients with HER2-positive BC.Notably,this synergistic effect of XLLXF was executed by enhancing NK cells and ADCC,as demonstrated through in vitro co-culture of NK cells and BC cells and in vivo inter-vention experiments.Mechanistically,the augmented impact of XLLXF on NK cells is linked to a decrease in cytokine inducible Src homology 2(SH2)containing protein(CISH)expression,which in turn activates the Janus kinase 1(JAK1)/signal transducer and activator of transcription 5(STAT5)pathway.Collectively,these findings suggested that XLLXF holds promise for enhancing NK cell function and sensitizing pa-tients with HER2-positive BC to trastuzumab.
