Neurobrucellosis: laboratory features, clinical characteristics, antibiotic treatment, and clinical outcomes of 21 patients.

BACKGROUND: Neurobrucellosis (NB) is a rare and serious complication of brucellosis. Its clinical manifestations vary, with no obvious specificity. At present, there is no clear clinical diagnosis or treatment for reference. In this study, we retrospectively analyzed the clinical data for 21 patients with NB to provide reference data for its further study. METHODS: We analyzed the epidemiological and clinical manifestations, laboratory tests, imaging examinations, cerebrospinal fluid, and treatment plans of 21 patients diagnosed with NB in the Department of Neurology, Xuanwu Hospital, Capital Medical University Beijing, China. RESULTS: The ages of the patients ranged from 15 to 60 years old (mean age 40.1 ± 13.33 years), the male: female ratio was 4.25:1. Thirteen patients had a history of animal (sheep, cattle) contact, three had no history of animal contact, and the contact status of four was unknown. Brucella can invade various systems of the body and show multi-system symptoms, the main general manifestations were fever (66.67%), fatigue (57.14%) and functional urination or defecation disturbance (42.86%). The main nervous system manifestations were limb weakness (52.38%) and hearing loss (47.62%).The main positive signs of the nervous system included positive pathological signs (71.43%), sensory abnormalities (52.38%), limb paralysis (42.86%). Nervous system lesions mainly included spinal cord damage (66.67%), cranial nerve involvement (61.90%), central demyelination (28.57%) and meningitis (28.57%). In patients with cranial nerve involvement, 69.23% of auditory nerve, 15.38% of optic nerve and 15.38% of oculomotor nerve were involved. The blood of eight patients was cultured for Brucella, and three (37.5%) cultures were positive and five (63.5%) negative. The cerebrospinal fluid (CSF) of eight patients was cultured for Brucella, and two (25.00%) cultures were positive and six (75.00%) negative. Nineteen of the patients underwent a serum agglutination test (SAT), 18 (94.74%) of whom were positive and one (5.26%) of whom were negative. A biochemical analysis of the CSF was performed in 21 patients, and the results were all abnormal. Nineteen patients underwent magnetic resonance imaging (MRI). Twenty-one patients were treated with doxycycline and/or rifampicin, combined with ceftriaxone, quinolone, aminoglycoside, or minocycline. After hospitalization, 15 patients improved (71.43%), two patients did not recover, and the status of four patients was unknown. CONCLUSIONS: The clinical manifestations, CSF parameters, and neurological imaging data for patients with NB show no significant specificity or correlations. When patients with unexplained neurological symptoms accompanied by fever, fatigue, and other systemic manifestations in a brucellosis epidemic area or with a history of contact with cattle, sheep, animals, or raw food are encountered in clinical practice, the possibility of NB should be considered. Treatment is based on the principles of an early, combined, and long course of treatment, and the general prognosis is good.

Efficacy of Ciji Hua'ai Baosheng formula on the expressions of vascular endothelial growth factor, kinase insert domain-containing receptor and basic fibroblast growth factor in mouse models of H(22) hepatocellular carcinoma.

OBJECTIVE: To investigate the efficacy of Ciji Hua'ai Baosheng formula (CHBF) on microvessel density (MVD) and vascular endothelial growth factor (VEGF), kinase insert domain-containing receptor (KDR) and basic fibroblast growth factor (bFGF) expression in serum and tumor tissue of mice receiving chemotherapy for the treatment of H(22) hepatocellular carcinoma. METHODS: Sixty Kunming mice were injected subcutaneously with H(22) hepatoma carcinoma cell suspensions into the right anterior armpit. Seven days later, all transplanted tumor were formed and the mice were intraperitoneally injected 200 mg/kg Cytoxan (CTX) to establish the models of tumor-bearing mouse chemotherapy, then they were randomly divided into model group, continuing CTX chemotherapy group (CTX group), and three CHBF (117, 58.5 and 29.25 g/kg) groups. After ten days of treatments, histology was observed, contents of VEGF, KDR and bFGF in serum and tumor tissue were measured by enzyme-linked immunosorbent assay (ELISA), VEGF and bFGF protein expression and MVD tagged by CD34 were detected by immunohistochemistry. RESULTS: MVD in CHBF (117, 58.5 g/kg) and CTX groups was significantly lower than that in model group (P < 0.01); expressions of VEGF, KDR and bFGF in serum and tumor tissue in CHBF (117 g/kg) group were less than those in model group (P < 0.05; P < 0.01); the expressions of MVD, VEGF and bFGF in tumor tissue of CHBF (117 g/kg) group were also less than those in CTX group (P < 0.05; P < 0.01). CONCLUSION: CHBF can effectively reduce the expression of VEGF, KDR and bFGF in serum and tumor tissue, and decrease MVD and delay tumor progression.

Effect of berberine on activity and mRNA expression of N-acetyltransferase in human lung cancer cell line A549.

OBJECTIVE: To study the effects of berberine on activity and mRNA expression of N-acetyltransferase in human lung cancer cell line A549. METHODS: N-acetyltransferase antibodies were prepared. The human lung cancer A549 cells were cultivated randomly in the wells of culture plate, and divided into the control group, and berberine 0.0008, 0.008, 0.08, 0.8 and 1.6 mM treatment groups, with 3 wells for each group. 24 h later, A549 cells in each group were collected respectively, the content of N-acetyltransferase was detected by Flow cytometry, and the mRNA expression of N-acetyltransferase was observed by reverse transcription polymerase chain reaction. RESULTS: The N-acetyltransferase content in human lung cancer A549 cells decreased with the increasing of berberine concentration, significantly lower than that in the control group (P < 0.05 or P < 0.001); and the mRNA expression of N-acetyltransferase also decreased with the increasing of berberine concentration, significantly lower in Huangliansu treatment groups (P < 0.001). CONCLUSION: Berberine can inhibit the activity of N-acetyltransferase in human lung cancer cell line A549, and shows negative correlations of dose and time in a certain extent. The inhibited gene expression of N-acetyltransferase in human lung cancer A549 cell may probably represent one of the mechanisms for its antineoplastic effect.

Regulatory effect of Yinchenhao decoction on bile acid metabolism to improve the inflammatory microenvironment of hepatocellular carcinoma in mice.

Hepatocellular carcinoma (HCC) is a malignant tumor with extremely high mortality. The tumor microenvironment is the "soil" of its occurrence and development, and the inflammatory microenvironment is an important part of the "soil". Bile acid is closely related to the occurrence of HCC. Bile acid metabolism disorder is not only directly involved in the occurrence and development of HCC but also affects the inflammatory microenvironment of HCC. Yinchenhao decoction, a traditional Chinese medicine formula, can regulate bile acid metabolism and may affect the inflammatory microenvironment of HCC. To determine the effect of Yinchenhao decoction on bile acid metabolism in mice with HCC and to explore the possible mechanism by which Yinchenhao decoction improves the inflammatory microenvironment of HCC by regulating bile acid metabolism, we established mice model of orthotopic transplantation of hepatocellular carcinoma. These mice were treated with three doses of Yinchenhao decoction, then liver samples were collected and tested. Yinchenhao decoction can regulate the disorder of bile acid metabolism in liver cancer mice. Besides, it can improve inflammatory reactions, reduce hepatocyte degeneration and necrosis, and even reduce liver weight and the liver index. Taurochenodeoxycholic acid, hyodeoxycholic acid, and taurohyodeoxycholic acid are important molecules in the regulation of the liver inflammatory microenvironment, laying a foundation for the regulation of the liver tumor inflammatory microenvironment based on bile acids. Yinchenhao decoction may improve the inflammatory microenvironment of mice with HCC by ameliorating hepatic bile acid metabolism.

Toxicity and clinical reasonable application of Taoren (Semen Persicae) based on ancient and modern literature research.

OBJECTIVE: To probe the toxicity and relative application theory of the commonly-used traditional Chinese herbal drug Taoren (Semen Persicae), and set up a correct attitude and principle and method to use Taoren (Semen Persicae) for treating the syndrome of stagnation of blood stasis and others in TCM clinic. METHODS: In this study, we analyzed and probed the ancient and modern literature research about Taoren (Semen Persicae), and summarized the realization of its toxicity and application contraindications in ancient herbals and the research assertion of its processing, drug-nature, pharmacologic actions, adverse reaction, and clinical reasonable application in modern literature. RESULTS: We found that some TCM doctors were worried about the effect of Taoren (Semen Persicae) 's disintegrating blood stasis to impair body's healthy Qi and its toxicity, and were not good at using this herb. And some patients were afraid of its toxic and side-effect not to take it. In the ancient and modern literatures some proper hates of Taoren (Semen Persicae) existed, and the toxicity component was also clear-cut, and the applications of Taoren (Semen Persicae) were in many fields especially the gynecological and traumatological diseases. The key root of toxicity generation and unreasonable application of Taoren (Semen Persicae) lies in taking without syndrome differentiation or using with overdosage. CONCLUSION: Under the precondition of correct processing, treatment based on syndrome differentiation, and taking the dosage stipulated by laws to apply Taoren (Semen Persicae) should be quite safe. The ancient and modern literature records and researches about Taoren (Semen Persicae) provide the determinate reference for understanding Taoren (Semen Persicae)'s efficacy and drug-nature (toxicity) more objectively and also for further correctly clinic recognition and research on Taoren (Semen Persicae).

Bushen Tongluo formula ameliorated testosterone propionate-induced benign prostatic hyperplasia in rats.

BACKGROUND: Benign prostatic hyperplasia (BPH) is a common disease in older men worldwide. However, there is currently no effective treatment for BPH. Bushen Tongluo Formula (Kidney-supplementing and collaterals-unblocking formula [KCF]) is a traditional Chinese medicine formula commonly used to ameliorate the symptoms of BPH, although the specific molecular mechanisms remain unclear. PURPOSE: We aimed to discover the effects and potential mechanisms of KCF against BPH. METHODS: Sixty male SD rats were randomly assigned to one of six group (n = 10): control, low-dosage KCF, medium-dosage KCF, high-dosage KCF, BPH model, and finasteride. A rat model of BPH was established by surgical castration followed by subcutaneous injection of testosterone propionate (TP) for 4 weeks. After treatment, the prostate index, histopathological staining, serum levels of estradiol (E2) and dihydrotestosterone (DHT), protein/mRNA levels of E-cadherin, TGF-ß1, caspase-3, Ki67, and vimentin, abundances of serum metabolites, and the proliferation, cell cycle, and apoptosis of BPH-1 cells were documented. RESULTS: KCF treatment for 4 weeks reduced the prostate volume and prostate index, alleviated histopathological changes to the prostate of rats with TP-induced BPH, decreased serum levels of E2 and DHT, reduced protein/mRNA levels of TGF-ß1 and vimentin, and increased E-cadherin levels. Moreover, KCF-spiked serum inhibited proliferation of BPH-1 cells, blocked the cell cycle, and promoted apoptosis. KCF was also found to regulate the contents of three metabolites (D-maltose, citric acid, and fumaric acid). CONCLUSION: The present study was the first to report that KCF exhibited therapeutic effects against BPH by regulating energy metabolism and inhibiting epithelial-mesenchymal transition in prostate tissues. Hence, KCF presents a viable treatment option for BPH.

Interaction between Chinese medicine and digoxin: Clinical and research update.

Background: Digoxin is one of the most widely and commonly used cardiac drug, which plays an irreplaceable role in treating heart failure and arrhythmia. The 2010 Edition of Pharmacopoeia of the People's Republic of China stipulates that the effective range of digoxin plasma concentration is 0.5-2.0 ng/mL and it is toxic at plasma concentration >2 ng/mL. Its effective plasma drug concentration is close to the toxic concentration, and large individual differences in the effects of the drug have been observed. It is often used in combination with other drugs, but drug interactions have a great impact on the plasma concentration of digoxin and lead to adverse reactions (ADRs), such as poisoning. Most of the reported drug interactions are with Western drugs. However, there are many combinations of traditional Chinese medicine (TCM) and Western drugs, TCM interacting with digoxin comprises monomer components, single medicines, and Chinese patent medicines. Aim of the study: We aimed i) to provide an overview of the TCM formulations affecting the pharmacology of digoxin and their mechanisms of action and ii) to provide a theoretical reference for the safe and rational use of digoxin in combination with TCM in clinical practice and to avoid ADRs. Methods: A literature search of electronic databases, including PubMed, MEDLINE, Cochrane Library, Web of Science, China National Knowledge Infrastructure, and WANFANG Data, was performed to search for articles published between 1 January 1960, and 1 August 2022. Search terms used included "digoxin," "traditional Chinese medicine," "Chinese patent medicine," and "adverse reactions" and their combinations. Results: A total of 49 articles were obtained, including clinical reports, pharmacological experiments and in vitro experiments. The mechanisms of action affecting the pharmacology of digoxin are complex. TCM formulations may affect the pharmacology of digoxin in vivo by influencing gastrointestinal motility or gastric juice pH, regulating P-glycoprotein levels, exerting cumulative pharmacological effects, and enhancing the sensitivity of the heart to digoxin. Although studies have shown that some TCM formulations interact with digoxin, they may be influenced by the complexity of the composition and the pharmacological effects of the TCM, the sensitivity of digoxin concentration determination methods, etc. The results of existing studies are controversial and further in-depth studies are required. Conclusion: Combinations of digoxin and TCM formulations are commonly used. This article serves as a reference to understand the interactions between TCM formulations and digoxin to avoid the occurrence of ADRs and improve the efficacy and safety of digoxin.

Fructooligosaccharides attenuate non-alcoholic fatty liver disease by remodeling gut microbiota and association with lipid metabolism.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a common liver disease highly associated with metabolic diseases and gut dysbiosis. Several clinical trials have confirmed that fructooligosaccharides (FOSs) are a viable alternative treatment for NAFLD. However, the mechanisms underlying the activities of FOSs remain unclear. METHODS: In this study, the effects of FOSs were investigated with the use of two C57BL/6 J mouse models of NAFLD induced by a high-fat, high-cholesterol (HFHC) diet and a methionine- and choline-deficient (MCD) diet, respectively. The measured metabolic parameters included body, fat, and liver weights; and blood glucose, glucose tolerance, and serum levels of glutamate transaminase, aspartate transaminase, and triglycerides. Liver tissues were collected for histological analysis. In addition, 16 S rRNA sequencing was conducted to investigate the effects of FOSs on the composition of the gut microbiota of mice in the HFHC and MCD groups and treated with FOSs. RESULTS: FOS treatment attenuated severe metabolic changes and hepatic steatosis caused by the HFHC and MCD diets. In addition, FOSs remodeled the structure of gut microbiota in mice fed the HFHC and MCD diets, as demonstrated by increased abundances of Bacteroidetes (phylum level), Klebsiella variicola, Lactobacillus gasseri, and Clostridium perfringens (species level); and decreased abundances of Verrucomicrobia (phylum level) and the Fissicatena group (genus level). Moreover, the expression levels of genes associated with lipid metabolism and inflammation (i.e., ACC1, PPARγ, CD36, MTTP, APOC3, IL-6, and IL-1ß) were down-regulated after FOS treatment. CONCLUSION: FOSs alleviated the pathological phenotype of NAFLD via remodeling of the gut microbiota composition and decreasing hepatic lipid metabolism, suggesting that FOSs as functional dietary supplements can potentially reduce the risk of NAFLD.

Antitumor mechanism of kangliu pill on gliomas in mice through PI3K-Akt signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Gliomas are common malignant intracranial tumors that have worse prognosis and pose a serious threat to human health. The Kangliu pill (KLP) is an innovative herbal compound from Xuanwu Hospital of Capital Medical University that has been clinically used for the treatment of gliomas for more than 40 years, and is one of the few drugs for primary treatment of this disorder. But the fundamental molecular mechanisms and pathways of KLP are not clear. AIM OF THE STUDY: To investigate the therapeutic mechanism of KLP in the treatment of gliomas. MATERIALS AND METHODS: An in situ xenograft model of red fluorescent protein-labeled human glioma cell line (U87-RFP) in BALB/c-nu mouse was established, and the therapeutic effect of KLP on gliomas was assessed by tumor weights and fluorescence areas. A quantitative proteomics approach using tandem mass tags combined with liquid chromatography-tandem mass spectrometry was performed to explore differentially expressed proteins (DEPs) in glioma tissues, and bioinformatics analyses including Gene Ontology analysis, pathway analysis, and network analysis were performed to analyze the proteins involved in the network therapeutic mechanisms responsible for key metabolic pathways. Cytological experiments corroborated the above analysis results. RESULTS: Network pharmacology approach screened 246 bioactive compounds contained in KLP, targeting 724 proteins and 173 potential targets of KLP for glioma treatment. The important targets obtained after visualizing the PPI network were AKT1, INS, GAPDH, SRC, TP53, etc. The KEGG enrichment results showed that 9 proteins were related to cancer, including Pathways in cancer, PI3K/AKT signaling pathway, etc. KLP had antitumor activity in gliomas, which reduced tumor weights and fluorescence areas. A number of DEPs possibly associated with gliomas were identified through quantitative proteomic techniques. Among these DEPs, 50 (25 upregulated and 25 downregulated) were identified that might be associated with KLP action. Bioinformatics showed that these 50 DEPs were mainly focused on focal adhesion, extracellular matrix (ECM)-receptor interactions, and the PI3K-Akt signaling pathway. Cytological experiments revealed that KLP significantly inhibited the proliferation and promoted apoptosis of U87-MG human glioma cells, and its mechanism was through the inhibition of PI3K/AKT signaling pathway. CONCLUSION: Therapeutic effect of KLP was regulation of multiple pathways in the treatment of gliomas. In specific, it interacts through the PI3K-Akt signaling pathway. This work may contribute proteomic insights for further research on the medical treatment of glioma using KLP.

Traditional Chinese medicine decoctions and Chinese patent medicines for the treatment of depression: Efficacies and mechanisms.

ETHNOPHARMACOLOGICAL RELEVANCE: Depression is a major mental disorder and it is currently recognized as the second-leading cause of disability worldwide. However, the therapeutic effect of antidepressants remains unsatisfactory. Traditional Chinese medicine (TCM) has been widely used for centuries, including commonly-used complementary and alternative medical therapies for depression. Recent clinical trials have been carried out to assess the efficacy and safety of TCM, and to explore the mechanisms of action in relation to the treatment of depression. AIM OF THE STUDY: To summarize frequently used TCM decoctions and Chinese patent medicines (CPM) for treating depression, review their clinical therapeutic effects in treating depressive disorders, consider their possible mechanisms, and characterize the relationships between their efficacy and mechanisms. MATERIALS AND METHODS: We performed a computerized literature search using the electronic databases such as PubMed, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang databases, with the keywords "depression", "traditional Chinese medicine decoction", "Chinese patent medicine", "application", "mechanism", and their combinations, from January 1, 2000 to August 8, 2022 (inclusive). RESULTS: A total of 51 papers were identified. We reviewed studies on six each TCM decoctions and CPMs, which demonstrated their significant clinical efficacy for treating depression and examined their mechanisms of action. The anti-depressive effects were related to: 1) increased monoamine neurotransmitter levels, 2) inhibiting hyperactivity of the hypothalamic-pituitary-adrenal axis, 3) regulating hippocampal neurons and neurotrophic factors, 4) regulating immune cytokines, 5) counteracting excitatory amino acid toxicity, and 6) regulating microbe-gut-brain axis function. CONCLUSION: TCM plays an increasingly important role in the management of depression by enhancing the therapeutic effects and alleviating the side effects of antidepressant chemicals.

Effects of hydroxy safflower yellow-A on tumor capillary angiogenesis in transplanted human gastric adenocarcinoma BGC-823 tumors in nude mice.

OBJECTIVE: To study the effects of hydroxy safflower yellow A (HSYA) on tumor capillary angiogenesis in transplanted human gastric adenocarcinoma BGC-823 tumors in nude mice. METHODS: BGC-823 cells were injected subcutaneously into the right anterior armpit of nude mice to establish an animal model of transplanted tumors. After 24 h, 18 nude mice injected with tumor cells were randomized into model, control, and HSYA 0.028 g/L groups, with six mice in each group. Transplanted tumors were excised on day 20. Tumor inhibition ratios were calculated for the transplanted tumors. Pathological changes and capillary angiogenesis in the tumors were observed by light microscopy. RESULTS: Tumors in the model group grew more quickly than those in the control and HSYA groups, with inhibition ratios of 48% and 30%, respectively. The microvessel count in the HSYA group was lower than in the model group (P < 0.01), and microvessel density was also lower in the HSYA group (P < 0.05). Pathological changes were more obvious in tumors in the model group compared to the HSYA group. CONCLUSION: HSYA inhibits the growth of transplanted BGC-823 tumors, and its effects on tumor capillary angiogenesis may represent one of the mechanisms responsible for this antineoplastic effect.

[Theoretical study on thirteen or fourteen incompatible medicaments and opposite drug properties of Tujia ethnic medical science].

Tujia ethnic medical science is an important sub-discipline of China's ethnic medicine system, which has rooted in major Tujia ethnic area such as Hunan, Hubei, Guizhou and Chongqing. It has its own theory, medication characteristic and experi-ence towards ethnic drugs. Particularly, in medication incompatibility, it has formed the principle of thirteen or fourteen incompatible medicament of traditional Tujia ethnic drugs, which play a certain role in guiding the usage and compatibility of tens of thousands of herbs. Focusing on the incompatibility that is abided by Tujia medical workers, the essay makes a textual study on the origin of herbs and conducts a preliminary study on the theoretical basis of thirteen or fourteen incompatible medicaments in terms of four properties of drugs and toxic and side-effect by reference to the records on nature and flavor and effectiveness, with a view of providing a preference to improve the incompatibility theory of traditional Chinese medicines and new ideas to further studies on the development and application of traditional ethnic drugs.

Comparison of growth features and cancer stem cell prevalence in intrahepatic and extrahepatic cholangiocarcinoma cell lines.

Aim of the study: Intra- and extrahepatic cholangiocarcinoma (I-CCA and E-CCA respectively) exhibit different growth features that contribute to different clinical outcomes. Cancer stem cells (CSCs) influence tumor growth and thereby may be responsible for these differences. The aim of this study was to document and compare the growth features of human I-CCA and E-CCA cell lines and determine whether any differences observed could be explained by differences in the prevalence and/or stem cell surface marker (SCSM) expression profiles of CSCs within the tumor cell lines. Material and methods: Six CCA cells lines, three I-CCA and three E-CCA, were studied. Tumor cell growth features including cell proliferation, colony/spheroid formation, migration and invasion were documented. CSC prevalence and SCSM expression profiles were examined by flow cytometry. Results: I-CCA cells had significantly increased proliferative activity, shorter doubling times and were more invasive than E-CCA cells, while colony/spheroid formation and migration were similar in the two cell populations. There were no significant differences in CSC prevalence rates or SCSM expression profiles. Conclusions: These findings suggest that I-CCA cells proliferate at a more rapid rate and are more invasive than E-CCA cells but the differences cannot be explained by differences in the prevalence or SCSM expression profiles of CSCs within the tumor cell population.

Effects of Sophora flavescens aiton and the absorbed bioactive metabolite matrine individually and in combination with 5-fluorouracil on proliferation and apoptosis of gastric cancer cells in nude mice.

Background: Sophora flavescens aiton (SFA) and its main bioactive metabolite matrine are widely used in traditional Chinese medicine (TCM) preparations and have achieved good curative effects for the treatment of various tumors. However, the mechanisms underlying SFA and matrine individually and in combination with chemotherapeutic drugs for treatment of gastric cancer (GC) remain unclear. Aim of the study: To elucidate the mechanisms underlying the ability of SFA and matrine individually and in combination with chemotherapeutic drugs to inhibit proliferation and promote apoptosis of human GC cells. Materials and methods: Forty-eight nude mice were randomly divided into six groups that were treated with normal saline (model group), 5-fluorouracil (5-FU), SFA decoction (SFAD), matrine, SFAD+5-FU, or matrine+5-FU. A subcutaneous heterotopic tumor model was established in nude mice by implantation of human GC BGC-823 cells. All mice were treated for 28 days. Bioactive metabolites in SFA were determined by HPLC-MS/MS. The tumor volume, tumor weight, and tumor inhibition rate of mice were documented. Histopathology and ultramicroscopic pathology of tumor tissues were observed. The tumor cell cycle and apoptosis in vivo were detected. Serum levels of PCNA, BAX, Bcl-2, Caspase-9, Caspase-3 and cleaved Caspase-3 were measured. Protein levels of MS4A10, MS4A8, MS4A7, PCNA, BAX, Bcl-2, Caspase-3, and cleaved Caspase-3 were measured in tumor tissues. Results: Both SFAD and matrine inhibited the growth of transplanted GC cells, which was more effective when combined with 5-FU. The tumor inhibition rates of the 5-FU, SFAD, matrine, SFAD+5-FU, and matrine+5-FU groups were 53.85%, 33.96%, 30.44%, 59.74%, and 56.55%, respectively. The body weight of tumor-bearing nude mice was greater in the SFAD group than the normal saline and matrine groups. SFAD+5-FU and matrine+5-FU blocked BGC-823 cells in the G0-G1/S transition, promoted apoptosis, and significantly decreased the content of serum apoptosis-inhibitory proteins (PCNA and Bcl-2) as well as protein expression of MS4A8, MS4A10, Bcl-2, and PCNA in tumor tissues, while increasing serum levels of pro-apoptotic proteins (Caspase-9, Caspase-3 and cleaved-Caspase-3) and protein expression of BAX and cleaved-Caspase-3 in tumor tissues. Conclusion: SFAD and matrine both individually and in combination with 5-FU ameliorated malignancy of transplanted tumors by reducing proliferation and promoting apoptosis of BGC-823 cells. These findings confirm the anti-tumor synergistic effect of TCM and chemotherapeutic drugs.

Partial response to Chinese patent medicine Kangliu pill for adult glioblastoma: A case report and review of the literature.

BACKGROUND: Glioblastoma is the most common type of brain tumor and is invariably fatal, with a mean survival time of 8-15 mo for recently diagnosed tumors, and a 5-year survival rate of only 7.2%. The standard treatment for newly diagnosed glioblastoma includes surgery followed by concurrent chemoradiotherapy and further adjuvant temozolomide. However, the prognosis remains poor and long-term survival is rare. This report aimed to demonstrate a new therapeutic strategy for the treatment of glioblastoma. CASE SUMMARY: A patient was referred to the Department of Neurosurgery with an intracranial space-occupying lesion with a maximum diameter of approximately 5 cm. The tumor was compressing functional areas, and the patient accordingly underwent partial resection and concurrent chemoradiotherapy. The imaging and pathological findings were consistent with a diagnosis of glioblastoma with oligodendroglioma differentiation (World Health Organization IV). The patient was finally diagnosed with glioblastoma. However, the patient discontinued treatment due to intolerable side effects, and was prescribed Kangliu pill (KLP) 7.5 g three times/d, which he has continued to date. Significant shrinkage of the tumor (maximum diameter reduced from about 3.5 to about 2 cm) was found after 3 mo of KLP therapy, and the tumor was further reduced to about 1 cm after 3 years. The patient's symptoms of headache, limb weakness, and left hemiplegia were relieved, with no side effects. CONCLUSION: KLP has been a successful intervention for glioblastoma, and the current case indicates that traditional Chinese medicine may offer effective alternative therapies for glioblastoma.

Interaction Between Chinese Medicine and Warfarin: Clinical and Research Update.

Background: Warfarin is a commonly used oral anticoagulant. It has a narrow therapeutic window and wide variation in individualized dosing, and is used clinically for the treatment of thromboembolic diseases. Due to the widespread use of traditional Chinese medicine (TCM) in China and the complex composition and diverse mechanisms of action of TCM, the combination of TCM and warfarin in patients has led to fluctuations in the international normalized ratio of warfarin or bleeding. To ensure rational clinical use, we summarize the TCMs with which warfarin interacts and the possible mechanisms, with a view to providing a clinical reference. Aim of the study: To summarize the mechanisms by which Chinese herbal medicines affect the enhancement or weakening of the anticoagulant effect of warfarin, to provide theoretical references for clinicians and pharmacists to use warfarin safely and rationally, and to avoid the adverse effects associated with the combination of Chinese herbal medicines and warfarin. Methods: A computerized literature search of electronic databases, including PubMed, MEDLINE, Cochrane Library, Web of Science (WOS), China National Knowledge Infrastructure (CNKI) and WANFANG Data was performed. Key words used in the literature search were "warfarin", "Chinese medicine", "traditional Chinese medicine", "Chinese patent medicine" etc. and their combinations in a time limit from January 1, 1990 to May 1, 2021. A total of 64 articles were obtained following the selection process, including clinical reports, pharmacological experiments and in vitro experiments which were reviewed to determine the mechanism of the anticoagulant effect of herbal medicine on warfarin. Results: The mechanisms affecting the anticoagulant effect of warfarin are complex, and herbal medicines may enhance and diminish the anticoagulant effect of warfarin through a variety of mechanisms; thus, clinical use needs to be cautious. Some herbal medicines have shown inconsistent results in both in vivo and ex vivo experiments, pharmacology and clinical studies, and should be the focus of future research. Conclusion: With the widespread use of TCM, the combination of warfarin and TCM is more common. This article will promote clinicians' knowledge and understanding of the TCMs which interact with warfarin, in order to avoid the occurrence of adverse clinical treatment processes, and improve the efficacy and safety.

The Ciji-Hua'ai-Baosheng II Formula Attenuates Chemotherapy-Induced Anorexia in Mice With H22 Hepatocellular Carcinoma.

Background: Ciji-Hua'ai-Baosheng II Formula (CHB-II-F) is a traditional Chinese medicine formula, which specifically targets different aspects of chemotherapy-induced adverse effects in patients with cancer. In our clinical application, CHB-II-F significantly alleviated chemotherapy-induced anorexia (loss of appetite) and improved the quality of life for patients with tumor during and after chemotherapy. However, the mechanism of CHB-II-F in alleviation of chemotherapy-induced anorexia remains to be further investigated. Aim of Study: To explore the therapeutic effect and mechanism of CHB-II-F on chemotherapy-induced anorexia in the mice model of H22 hepatoma. Materials and Methods: A total of 72 Kunming mice of SPF grade were inoculated subcutaneously with H22 hepatoma cells into the right anterior armpit of the mice. After 1 week of seeding, mice were injected intraperitoneally with a high dose of 5-fluorouracil (200 mg/kg 5-FU) to establish the model of chemotherapy. The mice were randomly divided into six groups: untreated group, 5-FU group, 5-FU plus Yangzheng Xiaoji capsule (YZXJC) group, and three groups of 5-FU plus different concentrations of CHB-II-F. All the mice in each group were treated for 14 days. The body weight, food intake, tumor volume, and tumor weight of mice were measured, and pathological examinations of tumor tissue, stomach, and duodenum were carried out. Expressions of serum Leptin, Neuropeptide Y (NPY), epidermal cell growth factor (EGF), Motilin (MTL), Orexin A (OXA), Gastrin (GAS), Ghrelin, Prostaglandin E2 (PGE2), and jejunum superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were examined. The protein and mRNA levels of proopiomelanocortin (POMC), Orexin receptor 1 (OX1R), neuropeptide Y (NPY), cocaine and amphetamine regulated transcript peptide (CART), Agouti gene-related protein (AgRP), Leptin receptor (Ob-R), and Ghrelin receptor (GHSR) were examined in hypothalamus, and the protein levels of substance P (SP) and 5-hydroxytryptamine (5-HT) in duodenum were measured. Results: The combination of CHB-II-F and 5-FU could enhance the inhibitory effect of 5-FU on tumor. The tumor inhibition rates of 5-FU group, YZXJC group, CHB-II-F(H) group, CHB-II-F(M) group, and CHB-II-F(L) group were 58.88, 28.08, 54.96, 37.69, and 28.61%, respectively. Compared with untreated group and 5-FU group, CHB-II-F significantly increased the body weight and food intake of tumor-bearing mice; increased the content of NPY, Orexin A, Ghrelin, GAS, MTL, EGF, and PGE2 in serum and the activity of SOD in jejunum; and decreased the content of Leptin in serum and the content of MDA in jejunum. Compared with untreated group and 5-FU group, CHB-II-F also enhanced the expression of OX1R, GHSR, NPY, and AgRP protein and gene and decreased the expression of Ob-R, POMC, and CART protein and gene in hypothalamus of mice, and the gene expression was consistent with the protein expression. In addition, CHB-II-F decreased the expression of 5-HT and SP protein in duodenum. Conclusion: In the murine model of H22 hepatocellular carcinoma (HCC) receiving chemotherapy, CHB-II-F enhances the inhibitory effect of 5-FU on tumor, significantly improves the pathological injury of gastrointestinal tract caused by chemotherapy, and regulates the secretion of gastrointestinal hormones. It may alleviate chemotherapy-induced anorexia by affecting appetite regulatory factors in the feeding area of hypothalamus central nervous system and peripheral appetite regulatory factors.

The Protective Effects of Zornia diphylla (L.) Pers. Against Acute Liver Injury Induced by Carbon Tetrachloride in Mice.

Background: Zornia diphylla (L.) Pers. (ZDP) is a traditional Chinese herbal medicine that has been used for several decades to treat patients with liver diseases. Whether ZDP is best administered as a single agent or adjunctive therapy has yet to be determined as does the mechanism whereby it exerts its effects on antagonizing acute liver injury (ALI). Aim of the study: To investigate the protective effects of ZDP on ALI induced by carbon tetrachloride (CCl4) and the potential underlying mechanisms. Materials and Methods: Sixty adult mice were randomized into six study groups (n = 10/group). Three groups were treated with different concentrations of ZDP (2.5, 1.25, 0.625 g/kg), one with bifendate (0.0075 g/kg) alone (positive control) and one with physiologic saline (normal, negative control). All groups were treated for 14 days. Two hours after the last administration, the normal group received an intraperitoneal injection of peanut oil, and the other five groups received an intraperitoneal injection of an equal dose of CCl4 peanut oil solution. At 24 h, the liver index, histology and serum or tissue levels and/or protein expression of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), alkaline phosphatase (ALP), superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), glutathione (GSH), Akt, phosphorylated Akt (p-Akt), nuclear factor kappa B p65 (NF-κB p65), inhibitor of NF-κB α (IκB-α), interleukin-1 ß (IL-1ß), interleukin-6 (IL-6), tumor necrosis factor α (TNF-α), E-cadherin and vimentin were determined. Results: Compared to the model controls, the degree of inflammatory cell infiltration and hepatocyte injury of liver tissue was relieved in the bifendate and three ZDP groups; liver index in the ZDP (2.5, 1.25 g/kg) groups and serum liver function indices in the ZDP (2.5, 1.25 and 0.625 g/kg) groups were decreased; antioxidants SOD, CAT and GSH in liver tissue were increased but the lipid peroxidation index MDA was decreased; protein expression of inflammatory cytokines Akt, p-Akt, NF-κB p65, IκB-α, IL-1ß, IL-6 and TNF-α in the liver was ameliorated, and E-cadherin expression was increased. The results of liver histopathology also showed that ZDP had a significant effect on ALI. Conclusion: ZDP has obvious protective effects on CCl4-induced ALI as a single therapy and appears to act by inhibiting oxidation, reducing the release of inflammatory factors and promoting hepatocyte repair.

[Current situation, problem analyses and its countermeasure of formulae of traditional Chinese medicine (FTCM) preventing and curing tumor angiogenesis].

Malignant tumor is the common disease that threaten severely to people's health. Formulae of traditional Chinese medicine (FTCM), as the major component of traditional drugs, has played more important role on the prevention and cure to tumor. The Folkman's theory that tumorous growth depends on tumor neovascularization has been confirmed so many years, so to inhibit the tumor angiogenesis, is an important path to treat tumor. The research of FTCM to antagonizing tumor angiogenesis in our country has been started more lately. Since it has been reported some FTCMs can inhibit angiogenesis, and it also exists many problems. The article summarized the correlated research of FTCM to antagonize tumor angiogenesis for the past several years, and according this, analyzed, stated and commented to the problems, countermeasures, development and direction of PTCM to antagonize tumor angiogenesis.

[Effects of HSYA on expression of bFGF protein and MMP-9 in BGC-823 transplantation tumor of nude mice].

OBJECTIVE: To investigate the effects of hydroxy safflor yellow A (HSYA) on the expression of bFGF protein and MMP-9 mRNA or protein of transplantation tumor of gastric adenocarcinoma cell line BGC-823 in nude mice. METHOD: The BGC-823 cells were subcutaneously injected into the right anterior armpit of BALB/C nu/nu nude mice, and the animal model of transplantation tumor was established. The experimental groups were treated with HSYA at concentration of 0.056 and 0.028 g x L(-1) and cyclophosphamide at 2 g x L(-1), or with physiologic saline. The tumor inhibitory effect was observed, and the mRNA expression of MMP-9 of transplantation tumor was detected by real time-fluorescent quantitation PCR and the protein expression of MMP-9 and bFGF were detected by enzyme linked immunosorbent assay. RESULT: The IR in the group with HSYA at the concentration of 0.028 g x L(-1) is higher than in the group with normal sodium. After treatment with HSYA, the mRNA expression of MMP-9 has significant difference at the concentration of 0.028 g x L(-1) as compared with physiologic saline-treated group (P < 0.05), but the protein expression of MMP-9 and bFGF is obviously less than that in the physiologic saline-treated group (P < 0.05). CONCLUSION: The possible mechanism of HSYA in given concentration to antagonize tumor angiogenesis may be related with inhibiting the protein expression of MMP-9 and bFGF or the mRNA expression of MMP-9 in tumor tissue to reduce the degradation of blood vessel basilar membrane, and to restrain the migration of blood vessel and decrease the tumor vascularization.
