Differences in MicroRNA Expression in Chronic Hepatitis B Patients with Early Liver Fibrosis Based on Traditional Chinese Medicine Syndromes.

The aim of this study was to determine if microRNA (miRNA) expression is different among chronic hepatitis B (CHB) patients with early liver fibrosis classified according to traditional Chinese medicine (TCM) syndromes. Eighteen CHB-fibrosis patients and 12 CHB patients without fibrosis were enrolled. The CHB-fibrosis group included 9 patients with the TCM syndrome of Ganyu Pixu Xueyu (GYPXXY), characterized by liver stagnation, spleen deficiency, and blood stasis, and 9 patients with the TCM syndrome of Qixu Xueyu (QXXY), characterized by deficiency of qi, blood, and blood stasis. Agilent miRNA microarray was performed first in liver specimens to determine whether miRNA expression is different in patients with these two TCM syndromes of CHB-fibrosis. Gene Ontology (GO) analysis and KEGG analysis were applied to determine the roles of the differentially expressed miRNAs. QRT-PCR was performed to validate the Agilent miRNA microarray results. Compared with GYPXXY patients, 6 differentially expressed miRNAs were upregulated (miR-144-5p, miR-18a-5p, miR-148b-3p, miR-654-3p, miR-139-3p, and miR-24-1-5p) and 1 was downregulated (miR-6834-3p) in QXXY patients. According to qRT-PCR data, miR-144-5p and miR-654-3p were confirmed as upregulated in CHB-liver fibrosis patients compared to CHB patients without fibrosis, whereas the other 4 miRNAs were not significantly different. More importantly, miR-654-3p was confirmed to be significantly upregulated in QXXY patients compared with values in GYPXXY patients, whereas no significant difference was found in miR-144-5p. Moreover, the pathways of central carbon metabolism in cancer and cell cycle related to miR-654-3p and the target genes of PTEN and ATM were found to be different between QXXY patients and GYPXXY patients. These results indicate that there are different miRNAs, pathways, and target genes between QXXY patients and GYPXXY patients. However, due to the limited sample, whether miR-654-3p and the target genes PTEN and ATM could be molecular markers to differentiate TCM syndromes could not be established.

CGY-1, a biflavonoid isolated from cardiocrinum giganteum seeds, improves memory deficits by modulating the cholinergic system in scopolamine-treated mice.

Certain biflavonoids have been proven to protect against cognitive dysfunction. A new biflavonoid, CGY-1, isolated from Cardiocrinum giganteum seeds, has not yet been reported to have any neuroprotective effect. In this study, a scopolamine-induced memory deficit model was used to explore the neuroprotective effect of CGY-1. Behavioral experiments, such as tests using the Morris water maze, the Y-maze and the fear conditioning test, were conducted. The results revealed that oral administration of CGY-1 (20 and 40 mg/kg) and donepezil shortened the escape latency, improved the percentage of spontaneous alternation, and increased the freezing times, respectively. CGY-1 decreased the levels of reactive oxygen species and malondialdehyde and increased the activities of superoxide dismutase and glutathione peroxidase in the hippocampus. In addition, CGY-1 decreased the activity of acetylcholinesterase and increased the activities of choline acetyltransferase and acetylcholine in the hippocampus. Furthermore, qPCR and western blot results revealed that the expressions of neurotrophic factors, brain-derived neurotrophic factor and nerve growth factor were upregulated in the hippocampus after CGY-1 treatment. In conclusion, CGY-1 could be a promising candidate for the treatment of cognitive dysfunction.

A clinical study on the treatment of chronic pelvic inflammation of Qi-stagnation with blood stasis syndrome by Penyanqing capsule.

OBJECTIVE: To observe the clinical efficacy of Penyanqing Capsule (PYQC) in treating pelvic inflammation of Qi-stagnation with blood stasis syndrome. METHODS: The randomized, single blinded, parallel positive drug controlled method was adopted, with 82 patients assigned into two groups by envelop method. The 42 patients in the treated group received PYQC 3 times a day, 4 capsules each time taken orally; the 40 patients in the control group were given orally Fuyankang tablets (FYKT) 3 times a day, 6 tablets each time. The therapeutic course for both groups was 2 months, and 2 courses of treatment were given successively to observe the comprehensive effect, changes of symptoms and signs before and after treatment. The effects of PYQC on hemorrheological character in part of the patients and on the pathogenetic chlamydia and mycoplasma were also observed. RESULTS: The total effective rate in the treated group was 83.3%, which was insignificantly different from that in the control group (77.5%, P > 0.05). However, PYQC could significantly lower the hemorrheologic indexes in patients and showed definite influence on the pathogenetic chlamydia and mycoplasma. CONCLUSION: PYQC has good therapeutic effect in treating chronic pelvic inflammation of Qi-stagnation with blood stasis syndrome, and showed definite effect on chlamydia and mycoplasma.
