Objective:To analyze active components， its targets and signaling pathways of Shenlian formula based on network pharmacology， and explore the molecular mechanism of Shenlian formula in the treatment of atherosclerotic cardiovascular disease （ASCVD）， in order to provide a basis for the rational interpretation of the prescription compatibility of Shenlian formula. Method:Major chemical compounds of the formula were obtained by SymMap and Systematic pharmacology database and analysis platform of Traditional Chinese Medicine （TCMSP）， its target proteins were obtained by SymMap and ETCM Databases， and the pathogenic genes responsible for of ASCVD were obtained by DisGeNET and GEO Datebases. Protein targets of drugs and pathogenic genes of diseases were overlapped to obtain predicted targets of Shenlian Formula for ASCVD. Proteins-proteins interactions （PPI） network was built through the String Datebase. The Cytoscape 3.6.0 was used to explore the key compounds and targets of Shenlian formula on ASCVD. Then gene ontology （GO） enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） signaling pathway were analyzed to screen out the key targets of Shenlian Formula. Rat I/R model was adopted as representative disease model of ASCVD for experimental verification. Result:There were 59 candidate compounds， 67 predicted targets and 29 key targets of Shenlian formula on ASCVD. Key targets mainly included cyclooxygenase 2 （PTGS2）， estrogen receptor 1 （ESR1） and TP53. GO analysis showed that the biological functions of potential genes of Shenlian formula in treatment of ASCVD were mainly related to apoptotic， nitric oxide biosynthetic process， response to estradiol， angiogenesis， inflammatory response and oxidative stress and acute-phase response. KEGG pathway enrichment results showed that the pathways of potential genes of Shenlian formula in treatment of ASCVD mainly involved TNF signaling pathway， phosphatidylinositol-3 kinase （PI3K）/ protein kinase B （Akt） signaling pathway， hypoxia induction factor-1 （HIF-1） signaling pathway and apoptosis. Among them， the regulatory effect of Shenlian formula on apoptosis may act on not only TP53， but also different signaling pathways of apoptosis respectively， thus playing a synergistic effect. In vivo experimentation confirmed that Shenlian formula could significantly reduce the myocardial infarction area， improve the myocardial histopathological changes， and especially reduce myocardial mitochondrial injury. Further analysis showed that Shenlian formula can significantly inhibit the expressions of activated proteins in mitochondrial apoptosis pathway. Conclusion:Anti-atherosclerosis traditional Chinese medicine Shenlian formula could effectively intervene ASCVD， and its effect on mitochondrial apoptosis of myocardial cells is one of its mechanisms in protecting myocardial ischemia-reperfusion injury.

Objective To study the application value of dynamic monitoring of blood pressure in the prevention and treatment of elderly hypertension. Methods 519 hypertensive patients from December 2017 to December 2018 were monitored with ambulatory blood pressure monitoring, and were divided into the elderly group (≥60 years old, 264 cases) and the control group (<60 years old, 255 cases). The results of ambulatory blood pressure monitoring in two groups were analyzed, which inclued the circadian rhythm of blood pressure, blood pressure, pulse pressure, coefficient of variation of blood pressure, blood pressure load value, average heart rate and morning blood pressure surge. Results The incidence of abnormal circadian rhythm of ambulatory blood pressure in the elderly group was 76.5%. Compared with the control group, there were differences in the indexes of diastolic blood pressure (DBP), diastolic blood pressure load value (DBPLV), pulse pressure (PP), 24 h average heart rate (24 hAHR), systolic blood pressure coefficient of variation (SBPCV), 24 h diastolic blood pressure coefficient of variation (24 h DBPCV) and morning diastolic blood pressure surge (MDBPS) between the two groups(all P<0.05). There were differences in 24 h systolic blood pressure (24hSBP), night systolic blood pressure (nSBP), night diastolic blood pressure (nDBP), night pulse pressure (nPP), day systolic blood pressure load value (dSBPLV), ninght systolic blood pressure load value (nSBPLV), 24 h SBPCV, 24 h dDBPCV and other indicators among different blood pressure types in the elderly group (all P<0.05). Conclusion Ambulatory blood pressure monitoring indicators have important guiding value for the prevention and treatment of elderly hypertension.

Prostate cancer is the most common malignancy in the reproductive system of older males. Androgen deprivation therapy (ADT) is an important treatment for prostate cancer patients. However, almost all prostate cancer patients unavoidably progress to the castration-resistant stage after ADT treatment. Recent studies have shown that tumor-associated immune cells play major roles in the initiation, progression, and metastasis of prostate cancer. Various phenotypes of tumor-associated immune cells have tumor-promoting or antitumor functions mediated by interacting with tumor cells. Here, we review the current knowledge of tumor-associated immune cells in prostate cancer.

Objective To observe the effect of the intensive training of core stabilization on the general function of patients with femoral neck fractures in old patients after hip arthroplasty. Methods From January, 2011 to December, 2012, 60 old patients accepted hip arthroplas-ty for femoral neck fractures were randomly divided into control group (n=30) and observation group (n=30). The control group received routine rehabilitation training 50 minutes each time, and the observation group received intensive training of core muscles 20 minutes each time based on the routine rehabilitation training 30 minutes each time, twice a day, five days a week for two weeks. Both groups were evalu-ated with Harris Hip Score (HHS), Charnley Hip Score (CHS) and modified Barthel Index (MBI) before training and one week, two weeks and three months after training. Results There was no significant difference in the scores of HHS, CHS and MBI before and one week after training (P>0.05). All the scores increased with time in both groups (F>248.165, P<0.001). The scores of HHS, CHS and MBI were signifi-cantly higher in the observation group than in the control group two weeks and three months after training (t>3.211, P<0.001). Conclusion Early intensive training of core stabilization may facilitate to recover hip function and activity of daily living in old patients after hip arthro-plasty.

OBJECTIVETo determine the amount of silver in silver-loaded coral hydroxyapatite (Ag(+)-CHA) bone substitute and its impact on the biocompatibility of this material with mouse embryonic osteoblast cells.

METHODSAg(+)-CHA was prepared by immersing coral hydroxyapatite in a serial concentration of silver nitrate solutions. The amount of silver in the prepared Ag(+)-CHA was measured by inductively coupled plasma atomic emission spectrometry (ICP-AES). The viability of MC3T3-E1 cells incubated with Ag(+)-CHA was measured by MTT colorimetric assay, and the cell growth and morphological changes were observed by inverted phase-contrast microscope and confocal laser scanning microscope.

RESULTSThe amount of silver loading in the bone substitutes prepared by immersion in 1×10(-2), 1×10(-3), 5×10(-4), 10(-4), 8×10(-5), and 5×10(-5) mol/L silver nitrate solutions were 4127.67∓47.35, 167.90∓11.00, 83.42∓4.51, 30.20∓2.32, 22.39∓4.09, and 15.11∓0.55 µg/g, respectively. A low silver content in the material (prepared with silver nitrate solution of less than 8×10(-5) mol/L) showed no significant inhibitory effect on the growth of MC3T3-E1 cells or produced noticeable cytotoxic effect. On the materials prepared with 8×10(-5) and 10(-5) mol/L silver nitrate solution, the osteoblasts displayed active proliferation similar to those incubated on materials without silver loading. The confluent cells showed a normal fusiform morphology with tight arrangement.

CONCLUSIONAg(+)-CHA with low silver content has a good biocompability and can promote the proliferation and growth of MC3T3-E1 cells in vitro, suggesting the clinical potential of this material as a anti-infection bone substitute.

OBJECTIVETo study the in vivo stability of normal and anterior cruciate ligament (ACL)-injured knee joint before and after epidural anesthesia under 134 N pre-loading and evaluate the influence of muscular tension on the knee stability.

METHODSEight volunteers with unilateral ACL rupture and normal contralateral knee were enrolled in this study. CT (3D) images and 2 orthogonal images of the knee were captured at 0°, 30°, 60°, and 90° under 134 N pre-loading. The orthogonal images were used to recreate the in vivo knee positions at each of the targeted flexion angles by 2D/3D registration to analyze the tibial translation data.

RESULTSThe anterior tibia translation of both the intact and ACL-injured knees after anesthesia was significantly different from that before anesthesia at all the angles (P<0.05). The anterior tibial translation of the intact knee after anesthesia increased by 1.7 mm at 0°, 2.7 mm at 30°, 2.6 mm at 60°, and 2.3 mm at 90°, as compare to the increase of ACL-injured knee by 4.2 mm, 2.6 mm, 1.2 mm, and 1.6 mm, respectively.

CONCLUSIONThe muscular tension has evident influence on the knee stability in static loading.

OBJECTIVETo investigate the expressions of VEGF in prostate cancer (PCa) and benign prostatic hyperplasia (BPH), their clinical significance and their relationship with that of ET-1.

METHODSA total of 44 specimens of PCa and 36 of BPH tissues were examined by the immunohistochemical Elivision plus method for the expressions of VEGF and ET-1. The intensity of staining for VEGF and ET-1 was assessed by light microscopy on a scale from "-" to "+ + +".

RESULTSThe rates of positive expression of VEGF were 69.4% in BPH and 80.9% in PCa, positive staining mostly in the cytoplasm of glandular epithelia and cancer cells, and strongly positive in all the stroma vascular endothelial cells. The staining intensity of VEGF was significantly higher in the PCa than in the BPH group (P < 0.05) , in the bone metastasis (BM) than in the non-BM group (P < 0.01), and in the lowly than in the highly and moderately differentiated PCa tissues (P < 0.01). The expression of VEGF was positively correlated with that of ET-1 ( r(s) = 0.780, P < 0.01).

CONCLUSIONVEGF is involved in the development, progression and metastasis of PCa. VEGF and ET-1 may play a joint role in its development and progression.
