Aim To explore the mechanism of Danshen decoction in the treatment of colon cancer using network pharmacology and molecular docking.Methods The active components and corresponding target proteins of Salvia miltiorrhiza, Santalum album and Amo-mum villosum in Danshen decoction were screened based on Traditional Chinese Medicine Systems Pharmacology database and analysis platform.The targets of colon cancer were searched by using Genecards database, and the common targets were selected.The network diagram of traditional Chinese medicine-active components-target-disease was constructed by using Cytoscape 3.7.0.The protein protein interaction network of common targets was constructed by using STRING database.The gene ontology(GO)and Kyoto Encyclopedia of Genes and Gnomes(KEGG)enrichment analysis were carried out based on R4.0.2.The important targets in the key pathways and the important active components in the network diagram of traditional Chinese medicine-active ingredients-target-disease network were selected for Surflex Dock.Results A total of 78 active components, 142 targets, 3 239 colon cancer targets, 105 overlapping targets and 69 corresponding active components were screened out.KEGG analysis showed that the key signaling pathway was PI3K/AKT.Luteolin and Tanshinone IIA with high correlation were selected to dock with protein kinase B(AKT1).Both active components had hydrogen bonding with AKT1.Conclusions Danshen decoction plays a positive role in colon cancer treatment.The mechanism may be related to the regulation of PI3K/AKT signaling pathway.

The purpose of this experiment is to observe the effects of Tongbi capsule on joint lesions in rabbit with rheumatoid arthritis induced by ovalbumin and explore the mechanism in order to provide reference for clinical application of Tongbi capsule. Rheumatoid arthritis in rabbits was induced by subcutaneous injection of emulsions of ovalbumin and Freund's complete adjuvant and intra articular injection of ovalbumin. After successful modeling, 30 New Zealand rabbits with arthritis were randomly divided into model control group, the high, medium and low dose groups of Tongbi capsule (90, 45, 22.5 mg·kg⁻¹) and prednisone group (5 mg·kg⁻¹). Another six normal rabbits were used as normal control group. After 24 hours of modeling, the rabbits in Tongbi capsule groups received intragastric (i.g.) administrations of Tongbi capsule at 90, 45, 22.5 mg·kg⁻¹·d⁻¹, and the rabbits of prednisone group received i.g. administrations of prednisone at 5 mg·kg⁻¹·d⁻¹ for 2 weeks. The rabbits in normal and model groups received the same volume of distilled water at the same time. The swelling degree of rabbit knee joint and local skin temperature were observed daily. After two weeks of administration, pathological changes of rabbit knee joint were examined by magnetic resonance imaging (MRI); the morphological changes of articular cartilage and synovial membrane were observed by microscope; and the contents of interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α) in serum were detected by enzyme linked immunosorbent assay (ELISA).The results showed that 24 h after modeling, the knee joints of the rabbits were swollen, with red or dark redlocal skin, and fever, elevated local skin temperature and increased diameters of knee joints. Two weeks after modeling, the swelling of rabbit knee joints was obvious in model group; the joint cavities were filled with purulent fluid; joint synovial membranes were obviously thickened, and even joint cavities were fibrotic and cartilage surfaces showed slight defect; the surface of articular cartilage was obvious fibrosis; synovial epithelial cell proliferation was obvious and accompanied by extensive inflammatory cell infiltration; the levels of IL-1 and TNF-α were significantly higher as compared with those seen in model rabbits (<0.05, <0.01). After 1 and 2 weeks of administration, knee joint diameters and local skin temperatures were smaller or lower than thosein model group (<0.05, <0.01); The lesions of joint cartilage and synovial of all rabbits in each group were less than those in model group; IL-1 and TNF-α levels in serum were also lower than those in model group (<0.05, <0.01). The results reveal that high and medium doses of Tongbi capsule can suppress rheumatoid arthritis induced by ovalbumin in rabbits, reduce joint swelling, inhibit synovial epithelial and fiber hyperplasia and inflammatory cell infiltration, and alleviate articular cartilage damage. The mechanism may be associated with decreasing IL-1 and TNF-α levels in serum.

OBJECTIVETo evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris.

METHODSBlock randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina.

RESULTSThe 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSII and III subgroups (P>0.05), while they were signifificantly better for KA in the CCSI and II subgroups (P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was signifificantly lower in the KA group than in the control group for the CCSII and III subgroups (9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01).

CONCLUSIONSKA is not inferior to NT in the remission of angina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).

OBJECTIVETo explore clinical effect of minimally corrective osteotomy for the treatment of hallux valgus with deformity of little toe varus through small incision.

METHODSFrom January 2013 to June 2016, 168 hallux valgus patients with deformity of little toe varus were treated by minimally corrective osteotomy through small incision. Among them, 7 males and 161 females were aged from 22 to 75 years old with an average of(59.3±3.5) years old. Preoperative clinical manifestation mainly focus on red and swollen of bunion, pain around with metatarsal bones, and diagnosed as hallux valgus with deformity of little toe varus through small incision. Operative time, postoperative complications, pre and post-operative IMA(angle between the first and the second metatarsal bones), HVA (hallux valgus angle), LDA(valgus angle of the fifth metatarsal bones), MPA(valgus angle of little toe), IM4-5 (angle between the forth and the fifth metatarsal bones) and PASA(fixed angle of proximal joint), postoperative AOFAS score were used to evaluate foot function.

RESULTSOne hundred and sixty-eight patients were followed up for 6 to 48 months with an average of (28.6±3.2) months. All wounds were healed well without infection, sinus tract and other complications. Operative time ranged from 16 to 28 min with an average of (18.3±2.1) min. IMA, HVA, LDA, MPA and IM A 4-5 were (10.1±2.1)°, (32.6±4.2)°, (6.9±2.3)°, (18.5±5.2)°, (15.1±2.9)°preoperatively, improved to (8.3±2.2)°, (10.9±2.9)°, (2.7±0.4)°, (6.5±1.6)°, (8.9±1.8)° postoperatively, and had significant differences before and after operation. While there was no difference in PASA before (9.1±2.1)°and after operation(8.7±1.9)°. AOFAS score were improved from (31.6±3.9) before operation to(83.7±5.2) after operation, but no significant difference(>0.05). According to AOFAS score, 147 patients obtained excellent results, 13 good, 6 moderate and 2 poor.

CONCLUSIONSMinimally corrective osteotomy for the treatment of hallux valgus with deformity of little toe varus through small incision could obtain satisfied clinical effect, and has advantages of small incision, no stitches, beautiful appearance, shorter operation time, and rapid recovery. It is worth popularization in clinical practise.

Objective To investigate the hemodynamic effect of stents with different types of links on treating vertebral artery stenosis, and provide scientific guidelines for the design of stent structure and the clinical procedure of stent intervention. Methods Models of vertebral artery with stenosis and three kinds of stents with different types of links (named as L-stent, V-stent and S-stentaccording to the shapes) were constructed by using Pro/Engineering. The expansions of these stents in the stenotic vertebral artery were simulated using ABAQUS, and three finite element models of the stented vertebral artery were then established for fluid flow analysis, and hemodynamic simulation was performed using ANSYS-CFX. Results Compared with V-link and S-link stent, L-link stent had smaller area of low wall shear stress distributions and smaller blood stagnation area. Conclusions With better hemodynamic effect, L-stent can potentially reduce the possibility of in-stent restenosis and provide scientific references for the choice of stent, the design of stent structure and surgical planning of stent intervention.

Objective To investigate the mechanical effect of stents with different links on the treatment of vertebral artery stenosis, and provide scientific guidelines for the design of stent structure and clinical procedure of stenting intervention. Methods Models of three kinds of stents with different types of links (namely, L-stent, V-stent and S-stent according to the shape of links) and vertebral artery with stenosis were established by using Pro/Engineering, then the same boundary conditions were exerted on the three models to simulate the stent deployed in the vertebral artery by finite element analysis using ABAQUS. Results Compared with L-stent and V-stent, S-stent had a better compliance, generating smaller stress in the arterial wall, causing relatively weak vascular straightening. Due to smaller stress and axial shortening generated in the stent strut, S-stent made less lesion on the arterial wall. Conclusions The therapeutic effect of S-stent is the best among the three kinds of stents, which could reduce in-stent-restenosis, and has good prospect in clinical application.

Stent intervention has become one of the most effective ways in treating cardiac and cerebral vascular stenosis. However, postoperative in-stent restenosis remains a major unsettled issue. The occurrence of in-stent restenosis is related not only to the mismatch between stent and artery, as well as the stress induced by mechanical support of the stent struts on arterial wall, but also to the intimal hyperplasia induced by the hemodynamic change. Recent literatures on biomechanics of the stented artery were reviewed in this paper. In particular, from the view of solid mechanics and hemodynamics, the research progress of stented artery in biomechanical simulation was given detailed discussion; moreover, the biomechanical factors associated with in-stent restenosis were analyzed and summarized. Numerical simulation is a good method for investigating the relationship between stent intervention and in-stent restenosis, and it also provides a scientific guideline for the design of stent structure and clinical procedure of stent intervention.

Objective The purpose of this study is to evaluate the in-hospital clinical outcome of patients with coronary artery disease who underwent transradial intervention (TRI) and analyze the predictors of chinical outcome. Methods From May 2004 to May 2009, there were 16 281 patients who underwent transradial intervention, as well as 5388 patients who underwent transfemoral intervention (TFI) at our institution. The clinical characteristics, procedural characteristics, and in-hospital clinical adverse events were compared between TRI and TFI groups. Multivariable logistic regression analysis was performed to determine predictors of in-hospital major adverse cardiac events ( composite of death, myocardial infarction,or target lesion revascularization) of TRI. Results The annulations time was significantly longer for TRIthan TFI (P ＜0. 01 ), fluoroscopy time, amount of contrast agent and procedural success rate (95.5% for TRI and 96. 2% for TFI) were similar between the two groups. However, the rates of vascular complications (0. 1% for TRI group and 1.3% for TFI group, P ＜0. 01 ), incidence of in-hospital major adverse cardiac events (1.6% vs. 3. 8%, P＜ 0.01) and in-hospital death (0.2% vs. 0.4%, P＜0.01) were all significantly lower in TRI group compared with TFI group. The following characteristics were identified as independent multivariate predictors of in-hospital major adverse cardiac events of TRI: age ≥65 ( OR: 1.98,95% CI: 1. 50 - 2. 61, P ＜ 0. 01 ), prior myocardial infarction ( OR:2. 14, 95% CI: 1.63 - 2. 82, P ＜0. 01 ), use of drug-eluting stent (DES) ( OR:0. 68, 95% CI:0. 47 - 0. 98, P = 0. 04 ), dissection during procedure (OR:4.08, 95%CI:2.28-7.33, P＜0.01), left main lesion (OR:2. 12, 95% CI:1.09-4. 13, P=0.03), number of implanted stents (OR:1.25, 95% CI:1.09 - 1.43, P ＜0.01), and total stented length (OR:1.01, 95% CI:1. 00 -1. 02 , P=0.03). Conclusions In this large single-centre patient cohort, the transradial intervention is superior to transfemoral intervention in terms of in-hospital safety and efficacy. Age ≥ 65, prior myocardial infarction, use of DES, dissection during procedure, left main lesion, number of implanted stents and total stented length were identified as independent multivariate predictors of in-hospital major adverse cardiac events of TRI.

OBJECTIVETo compare the short-term clinical outcome of non-fusion techniques using interspinous implantation Coflex(TM) and Wallis treatment in patients with lumbar spine degenerative diseases.

METHODSForty-one cases of lumbar stenosis, 18 of lumbar disc herniation, and 34 of lumbar stenosis with lumbar disc herniation were evaluated. Among the 43 cases receiving Coflex(TM) implantation, 41 had operations in one segment and 2 in 2 segments. In the other 50 cases with Wallis implantation, 47 had fixation of 1 segment and 3 had 2 segments fixed. JOA Score, Oswestry Disable Index (ODI) and VAS were used to evaluate the short-term clinical results.

RESULTSThe average operating time was 64.55 min in Coflex(TM) implantation with an average blood loss of 81.82 ml. The average operating time was 82.71 min in Wallis implantation, which caused an average blood loss of 89.66 ml. Significant improvements in the JOA Score, ODI and VAS were noted after the operations.

CONCLUSIONThe two interspinous non-fusion techniques, Coflex and Wallis, produce good short-term clinical outcome in the treatment of lumbar spine degenerative diseases.

BACKGROUNDCoronary artery disease (CAD) is generally considered as a disease of middle-aged men. It is widely accepted that the risk for CAD of premenopausal women is low because of hormone protection. Based on our clinical experience, more and more premenopausal women suffer from angina and myocardial infarction without adequate concern. Even now, there are still limited detailed data to describe the characteristics, mechanism and prognosis of premenopausal CAD patients. This article aimed to analyze the clinical and angiographic characteristics of premenopausal women with CAD.

METHODSA total of 565 premenopausal women and 721 postmenopausal women (56 - 60 years old) who underwent coronary angiography for the first time from April 2004 to December 2007 were enrolled. The clinical data and coronary angiographic characteristics (presence, localization, length and severity) were compared between the premenopausal and postmenopausal CAD groups.

RESULTSPremenopausal CAD patients presented less frequently with hypertension, diabetes mellitus and dyslipidemia compared with postmenopausal CAD patients (55.0% vs 66.0%, 15.0% vs 31.5%, 23.9% vs 37.4%, respectively; all P < 0.05). Although we found more frequent involvement of single vessel in premenopausal CAD (43.2% vs 26.9%, P = 0), and triple vessels in postmenopausal (56 - 60 years old) CAD patients (33.8% vs 20.4%, P = 0), much more severe lesions (> or = 90%) at left main (2.9% vs 1.1%, P = 0.048) and proximal left anterior descending artery (LAD) (28.2% vs 16.6%, P = 0) in the premenopausal CAD group were found.

CONCLUSIONPremenopausal women with chest discomfort are always found to have obvious atherosclerosis, more inclined to be located at the left main and proximal LAD, which is a strong predictor of an adverse clinical outcome.
