Abstract: Objective To elucidate the potential mechanism of Jindanjiangan Capsule in the treatment of liver fibrosis by network pharmacology and molecular docking. Methods Active ingredients and targets of Jindanjiangan Capsules were searched by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and HERB databases, and the disease targets were screened by DisGeNET and Therapeutic Target Database (TTD) databases. The targets of the active ingredients of Jindanjiangan Capsule were matched with the disease targets, and the common targets were imported into the String database platform to construct a protein-protein interaction network (PPI) network. CytoNCA tool of Cytoscape 3.9.1 software was used for topological analysis to screen key targets. Traditional Chinese Medicine-Key Active IngredientsKey Target Network was constructed by Cytoscape 3.9.1 Software. KEGG enrichment analysis of key targets was performed through the DAVID platform. The molecular docking of active ingredients and targets was performed to verify the above results using LeDock software. Results By screening, 180 potential active ingredients and 1 340 targets of Jindanjiangan Capsule and 1 060 targets of liver fibrosis, and 273 common targets were obtained. 29 key targets related to liver fibrosis were screened out by PPI network interaction, and verified by KEGG analysis and molecular docking. Jindanjiangan capsule acts on key targets such as EGFR, MMP9, PTGS2, ESR1, PIK3CA, F2, PPARG, and PTPN11 through active components such as isovitexin, quercetin 7-O- β -D-glucoside, (3S, 6S) -3- (benzyl) -6- (4-hydroxybenzyl) piperazine-2, 5-quinone, 6-Osyringoyl-8-O-acetylshanzhiside methyl ester, tanshinone II, nortanshinone, capillaris chromone, and etanone. The specific mechanism may be related to HIF-1 signaling pathway, C-type lectin receptor signaling pathway, Toll-like receptor signaling pathway, tumor necrosis factor signaling pathway, relaxin signaling pathway, FoxO signaling pathway and so on. Conclusion Jindanjiangan capsule can effectively treat hepatic fibrosis through multi-component, multi-target and multi-pathway.

Objective To investigate the interference and associated mechanism of hnman tissue kallikrein (HK) gene on renal interstitial fibrosis in rats with 5/6 nephrectomy. Methods Human kallikrein cDNA was packed in a recombinant adeno-associated virus(rAAV)-based plasmid vector. The rAAV-HK was produced by transfection in 293 cells. Twenty-four male Wistsr rats were divided into sham operation and operation groups. The rats with 5/6 nephrectomy were randomly divided into simple operation, control and experiment groups. The rats in experiment group received single dose rAAV-HK via the tail vein with 1×1011 pfu. Before nephrectomy and every month after surgery until the rats were sacrificed, the caudal arterial pressure was measured using tail cuff blood pressure determinator. Three months after HK gene delivery, the rats were sacrificed. The expression of HK in rats was assessed by RT-PCR, Western blot and enzyme-linked immunosorbent assay (ELISA). The pathological changes of renal interstitium were evaluated by Masson stainning, and the distribution of bradykinin B2 receptor (BKB2R) and angiotensin Ⅱ typel receptor (ATIR) was examined by immunohistochemistry. The expressions of BKB2R, AT1R, p-MAPK protein in renal tissue were detected by Western blot. Results Three months after HK gene delivery, the systolic blood pressure of experiment group was significantly decreased compared with the control group [(163±13) nun Hg vs (217±16) mm Hg, P<0.01](1 mm Hg=0.133 kPa). Compared with sham rats, the rats in simple operation group and control group had much more renal interstitial collagen deposition and more serious fibrosis performance, but renal interstitial collagen deposition and fibrosis were significantly ameliorated in the rats of experiment group. In addition, the tubulointerstitial injury index of HK transgenic rats was significantly lower than that of the rats in control group (1.33±0.73 vs 3.01±0.62, P<0.01). Up-regnlating expression of bradykinn B2 receptor protein and down-regulating expression of AT1 receptor and p-MAPK protein were found in renal tissues of experimental group after three months (P<0.05). Conclusion HK gene delivery significantly alleviates renal interstitial fibrosis in rats with 5/6 nephrectomy through regulating the expression of bradykinin B2 receptor, AT1 receptor and p-MAPK in renal tissue.

Objective EGFR targeted therapy mediated by adeno-associated virus is a promising way to treat pancreatic cancer.This study aimed to assess the feasibility and activity of combining rAAV-anti EGFR,gemcitabine,and radiation in pancreatic cancer cells.Methods Aspc-1 human pancreatic carcinoma cells were divided into several groups,in vitro and in vivo,which were respectively exposed to gemcitabine alone,radiation alone,rAAV-anti EGFR alone,the combination of rAAV-anti EGFR with gemcitabine,the combination of rAAV-anti EGFR with radiation,and the combination of all three agents.The pancreatic cancer tumor growth and apoptotic rate were measured.Results The apoptotic rate was higher in cells treated with a single or combination of agents compared to the negative control (P＜0.05).The combination of rAAV-EGFR,gemcitabine,and radiation produced the highest induction of apoptosis compared to a single agent alone (P ＜ 0.05).Treatment with rAAV-anti EGFR greatly inhibited growth in the tumor xenografts (P＜0.05),and a synergistic effect of rAAV-anti EGFR,gemcitabine,and radiation was found.The number of tissue cancer cells that expressed cleaved caspase-3 after treatment with rAAV EGFR was more than that of the control group (P＜0.05).The combined treatment of rAAV-anti EGFR,gemcitabine,and radiation induced the highest numbers of cells expressing cleaved caspase-3 compared to that with a single agent alone (P＜0.05).Conclusions The rAAV-anti EGFR therapy in combination with chemotherapy and radiation therapy demonstrated a greater efficacy over therapy with a single agent alone.rAAV-anti EGFR increased the efficacy of gemcitabine and radiation in the treatment of pancreatic cancer cells.

Objective To evaluate the significance of tumor markers CEA and CA15-3,and biochemical markers of bone turnover (total procol]agen type Ⅰ amino-terminal propeptide (TP I NP),β-isomerized carboxyterminal propeptide (β-CTx),ALP and PTH) in the diagnosis of bone metastasis from breast cancer.Methods A total of 78 patients (all females) with mean age (56.72 ± 10.76) years,who were diagnosed with breast cancer,were included in this study.The patients were divided into two groups based on radionuclide bone imaging:with bone metastasis (n =32) and without bone metastasis (n =46).The serum concentrations of CEA,CA15-3,TP I NP,[β-CTx,PTH,ALP were measured.Gleason scores were evaluated.The diagnostic value was evaluated by ROC curve.The two groups were compared using two-sample t test.The correlations between bone metastasis and tumor markers,bone metastasis and biochemical markers of bone turnover were analyzed with Pearson correlation and logistic analysis.Results The serum levels of CEA,CA15-3,TPINP,β-CTx,PTH and ALP were significantly higher in the group with bone metastasis than those in the group without bone metastasis (t:4.16-7.56,all P ＜ 0.05).For the diagnosis of bone metastasis from breast cancer,the AUC of CEA,CA15-3,TPINP,[β-CTx,PTH and ALP was 0.815,0.887,0.869,0.852,0.844,0.731,respectively.Using the cut-off values of 4.18 μg/L for CEA,0.04 U/L for CA15-3,49.70 μg/L for TP I NP,0.47 pg/L for β-CTx,54.90 ng/L for PTH and 49.90 U/L for ALP,the sensitivities were 56.3％ (18/32),75.0％ (24/32),78.1％ (25/32),81.3％ (26/32),78.1％ (25/32),68.8％ (22/32) and the specificities were 80.4％ (37/46),84.8％ (39/46),76.1％ (35/46),78.3％ (36/46),69.6％ (32/46),58.7％ (27/46),respectively.CEA,CA15-3,TPINP,β-CTx,PTH,ALP and Gleason score were positively correlated with the presence of bone metastasis (r:0.267-0.636,all P ＜ 0.05).CEA,CA15-3,TP I NP,β-CTx,PTH and Gleason score were independent predictors for bone metastasis of breast cancer (odds ratios:2.45,3.44,1.24,1.54,1.11,2.22,all P ＜0.05).The total coincidence rate of regression model was 81.3％ (26/32) in patients with bone metastasis.Conclusions The diagnostic values of CEA,CA15-3,TP I NP,β-CTx and PTH are comparable.Combined use of these parameters may be helpful for the early diagnosis of bone metastasis from breast cancer.
