Explore Potential Molecular Mechanism of Gegen Qinliantang in Intervention of Atherosclerosis Based on Network Pharmacology and Molecular Docking / 中国实验方剂学杂志

ObjectiveThis study aims to explore the potential molecular mechanism of Gegen Qinliantang （GQL） in the intervention of atherosclerosis （AS） based on network pharmacology and molecular docking. MethodThe active components and targets of each medicinal in GQL were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and AS-related genes from 7 databases. Thereby， the anti-AS targets of GQL were screened out. Cytoscape 3.8.0 was employed to construct the "component-target" network， and STRING the protein-protein interaction （PPI） network. Core targets were screened out with CytoNCA. R clusterProfiler was used for Gene Ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment of target genes， which were then visualized. Finally， molecular docking of the top ten active components with the core targets of AS was performed and the binding affinity was compared with that between atorvastatin and the core targets. ResultIn the end， 150 active components of GQL， 20 289 AS targets， and 213 common targets were retrieved， and 48 core common targets were screened out. They were mainly involved in the GO terms of nuclear receptor activity， ligand activation， and transcription factor activity and the pathways of fluid shear force and AS， advanced glycation end products-receptor for advanced glycation end products （AGE/RAGE）， interleukin-17 （IL-17）， tumor necrosis factor （TNF）， Toll-like receptor pathways and other signaling pathways closely related to AS. The molecular docking results showed that the effective components of GQL had high binding affinity to core targets of AS， and the binding affinity was even higher than that between the atorvastatin and core targets. The five groups with high binding affinity were puerarin-TNF， baicalein-inducible nitric oxide synthase 2 （NOS2）， puerarin-NOS2， and formononetin-NOS2， wogonin-NOS2. ConclusionThe above result provides new ideas for further exploration of this classical decoction.

Effect of Jieyu Tongluo Method in Regulating Levels of Neurotransmitter from Patients with Post-stroke Depression / 中国实验方剂学杂志

Objective: To observe the clinical efficacy of Jieyu Tongluo decoction on post-stroke depression (PSD) and its regulatory effect on neurotransmitter. Method: One hundred and twenty-five patients with PSD were randomly divided into control group (62 cases) and observation group (63 cases) by random number table. Both groups got psychological support, health education, and sertraline hydrochloride tablets, 25-50 mg/time, 2 times/days. Patients in control group got Shugan Jieyu capsules, 2 grains/time, 2 times/days. Patients in observation group got Jieyu Tongluo decoction, 1 dose/day. And a course of treatment was 6 weeks. Before and after treatment, hamilton depression scale (HAMD-17), patient health questionnaire-9 (PHQ-9), national institutes of health stroke scale (NHISS),traditional Chinese medicine(TCM) syndrome and activity of daily living scale (ADL) were scored. And levels of 5-serotonin (5-HT), norepinephrine (NE), dopamine (DA), brain-derived neurotrophic factor (BDNF), serum S100-β and neuron enolase (NES) were detected. Result: By rank sum test, after treatment, the clinical efficacy of observation group was superior to that in control group (Z=2.384, PPZ=2.266, PZ=2.817, Pβ and neuron enolase (NES) were lower than those in control group (PPConclusion: In addition to psychotherapy and SSRI, Jieyu Tongluo decoction can relieve degree of depression, depressive symptoms and degree of neurologic impairment, increase activities of daily living, regulate neurotransmitter expression, and improve the reparation of cranial nerve tissue, with obvious clinical effects, and is worthy to be used in clinic.

Effect of ruji recipe on the post-surgical survival of female breast cancer patients / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effect of Ruji Recipe (RR) in preventing disease recurrence/metastasis and improving quality of life (QOL) for female breast cancer patients after operation.</p><p><b>METHODS</b>Totally 102 female patients with stage I - III breast cancer were retrospectively analyzed. They were assigned to the treatment group (54 cases) and the control group (48 cases) according to whether they would rather accept RR therapy. Estrogen receptor/progesterone receptor (ER/PR) positive patients also accepted endocrine therapy. The overall survival (OS), disease-free survival (DFS), recurrence and metastasis, and QOL were compared between the two groups.</p><p><b>RESULTS</b>Totally 100 patients completed the study. The median follow-up was 59 months. The median OS was 60 months in the treatment group and 52.5 months in the control group (chi2 = 3.274, P > 0.05). The median DFS was 55.0 months in the treatment group and 47.5 months in the control group (chi2 = 10.145, P < 0.01). The DFS rate was 75.9% (41/54) in the treatment group and 54.3% (25/46) in the control group (chi2 = -2.259, P < 0.05). There was statistical difference in the 2-, 3-, and 5-year DFS between the two groups (P < 0.01). There was statistical difference in the 2-year DFS 3-year DFS between stage II and III and stage III (P < 0.05, P < 0.01). There was statistical difference in the ER positive patients between 2-year DFS and 3-year DFS (P < 0.01, P < 0.05). There was statistical difference in the 3-and 5-year distant metastasis rate (DMR) in the treatment group, lower than that of the control group (3.7% vs 31.0%, 20.7% vs 60.7%; P < 0.01). By the end of follow-up, disease progression occurred in 13 cases of the treatment group, local recurrence in 3 cases, single organ metastasis in 7 cases, multi-metastasis in 3 cases, while the corresponding numbers were 21, 1, 11, and 9 in the control group (P < 0.05). As for 1 week before study and at 2-year follow-up using Functional Assessment of Cancer Therapy for Breast Cancer (FACT-B) system, there was statistical difference in the QOL between the two groups (P < 0.05), and better effect was obtained in the treatment group.</p><p><b>CONCLUSION</b>RR, as an assistant therapy, could improve the OS rate, the DFS rate, and the QOL for post-surgical female breast cancer patients in 2 -3 years.</p>

Effects of acupoint area and non-acupoint area of eye-acupuncture on expressions of VIP and AQP 8 in colonic tissues in rats with D-IBS / 中国针灸

<p><b>OBJECTIVE</b>To explore the point specificity of eye-acupuncture and the mechanism of eye-acupuncture on diarrhea-predominant irritable bowel syndrome (D-IBS).</p><p><b>METHODS</b>Forty male Wistar rats of SPF grade were randomly divided into a normal group, a model group, a eye-acupuncture point (AA) group and a non-point (NA) group. The D-IBS rat model was established with the combination methods of the chronic stress and binding limbs. The AA group was treated by acupuncture at "low energizer area", "large intestine area", "liver area" and "spleen area", and the NA group by acupuncture at 3 mm apart from the same points area mentioned above, and the normal group and the model group with no intervention. The rate of feces moisture content was detected. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA of aquaporin 8 (AQP 8) in colon. Protein expressions of the vasoactive intestinal peptide (VIP) and AQP 8 in colon were detected by SABC immunohistochemistry method.</p><p><b>RESULTS</b>Compared with normal group, the rate of feces moisture content at the 18th and 25th days, VIP protein in colon mucosa, myenteric nerve plexus and hypo-mucosa nerve plexus increased significantly (all P < 0.01), and AQP 8 mRNA in colon mucosa decreased significantly in model, AA and NA group (P < 0.05, P < 0.01); AQP 8 protein in colon mucosa decreased significantly in model group and NA group (both P < 0.01). Compared with model group, the rate of feces moisture content at the 25th day and VIP protein in colon mucosa decreased significantly (P < 0.01, P < 0.05), and AQP 8 mRNA and protein increased significantly (P < 0.05, P < 0.01) in AA group. Compared with AA group, the rate of feces moisture content at the 25th day and VIP protein in colon mucosa increased significantly (both P < 0.01), and AQP 8 mRNA and protein decreased significantly (both P < 0.01) in NA group.</p><p><b>CONCLUSION</b>Eye-acupuncture has a good therapeutic effect on D-IBS. It is suggested that one of the mechanism is relate to increase AQP 8 in colon tissue and restrain the expression of VIP. Non-point area of eye-acupuncture has no obviously therapeutic effect and so to illustrate the point specificity of eye-acupuncture.</p>
