Objective To identify the targeted-regulating relationship between human MicroRNA335 (hsa-miR-335 )and CCL1 1,CCL26 and SOX4.Methods The potential fragments of hsa-miR-335 target genes CCL1 1,CCL26 and SOX4 were predicted by the bioinformatics analyzing tools online.The 3′untranslated regions(3′UTR)of the CCL1 1,CCL26 and SOX4 were connected to the eukaryotic expression vectors pMIR REPORT.The constructs of pMIR-REPORT-CCL1 13′UTR,pMIR-REPORT-CCL26 3′UTR,pMIR-REPORT-SOX4 3′UTR and positive control were co-transfected with Pre-miRTM miRNA335 Precursor or negative control into 293 T7/1 7 cell line by lipofectamine 2000,respectively.Both Firefly and Renilla luciferase activity were detected by dual luciferase reporter assay system.Results Compared with the negative control group,luciferase assay revealed that has-miR-335 could significantly diminish luciferase activity from SOX4 reporter vector (P <0.01 ),while the suppression of luciferase activity was not found in CCL1 1 or CCL26 reporter vector (P >0.05).Conclusion The results suggested that hsa-miR-335 targeted regu-lated SOX4,but not targeted CCL1 1 and CCL26.

Objective To observe the effects of Xinshuaiheji (XSHJ) on cardiac function, plasma angiotensin Ⅱ (AngⅡ) and histomorphology in rats with heart failure after acute myocardial infarction. Methods A model of heart failure (HF) induced by myocardial infarction (MI) in rats was made, 10 days after MI, rats were treated for 4 weeks with bidist Water, Captopril, high dosage of XSHJ, low dosage of XSHJ. The effects of Xinshuaiheji on cardiac function (stroke volume, SV, cardiac output, CO, cardiac index, CI ) and AngⅡ were observed. We also observed and compared the changes of heart weight/body weight ratio (HW/BW), ratio of ventricular wall thinning in MI. Results After treatment with XSHJ, the cardiac function (SV, CO, CI) of HF rats improved (P

OBJECTIVETo observe the effects of Xinshuai Mistura (XM) on plasma angiotensin II (Ang II), atrial natriuretic peptide (ANP) and N terminal pro- brain natriuretic peptide (Nt-proBNP) in patients with heart failure (HF).

METHODSFifty-nine patients with HF (NYHA class II-IV) were randomly divided into two groups, the treated group treated with XM and the control group with Wuling Pulvis (WP), both on the base of captopril treatment. The treatment course was two weeks. Plasma levels of Ang II , ANP and Nt-proBNP were observed.

RESULTSThe plasma levels of Ang I, ANP and Nt-proBNP showed an ascending tendency along with the increasing in severity of HF(P < 0.01), and significantly decreased after treatment in the treated group (P < 0.01), but with no remarkable difference as compared with those in the control group (P > 0.05).

CONCLUSIONXM had definite therapeutic effects on excessive neuroendocrine activation in HF patients.

Objective To explore the biomechanical characteristics of the pharynx in patients with aspiration after radiotherapy for nasopharyngeal carcinoma (NPC).Methods Clinical data on NPC patients with dysphagia admitted between July 2011 and June 2015 were retrospectively analyzed.Twenty-three patients were found who had received videofluoroscopic swallowing studies (VFSSs) and whose pharyngeal pressure and upper esophageal sphincter (UES) relaxing were tested using high-resolution solid-state manometry (HRM).The cases were divided into an aspiration group and a non-aspiration group according to the VFSS results.Differences in biomechanical parameters between the 2 groups when taking food of different viscosity were compared.Results Patients with aspiration had significantly higher UES residual pressure when taking thick liquids (20.1± 14.3 mmHg) and paste (18.0± 14.3 mmHg) than patients not aspirating (9.3±9.2 mmHg and 7.2±8.9 mmHg for thick liquid and paste respectively).But no significant difference in average pharyngeal pressure between the two groups was observed.Conclusion Aspiration after radiotherapy may be correlated with increased UES residual pressure.

Objective　To study the corelation between patient with inflammatory polyp of large intestine and the changes of immunologic function. Methods　Polyps of large intestine were extirpated from 120 patients with fiberoptic colonoscope and the pathological changes were studies. IgG subclass and T cell subsets in the peripheral blood were determined by ELISA and IFA methods. Similar parameters were determined in 30 cases of chronic colitis as control. Results　CD8 in patients were lower than that of the control and CD4/CD8 were increased compared with those in control. Conclusion　Disorder of humoral and cellular immunity might play an important role on the pathogenesis of polyp of large intestine.

Ten compounds were isolated from the artificially induced dragon's blood of Dracaena cambodiana by various column chromatographies on silica and sephadex LH-20 gel. Based on spectral analysis of NMR and MS, their structures were identified as 3, 4-dihydroxyallylbenzene (1), 3', 4', 5'-trimethoxycinnamylalcohol (2), pinoresinol (3), (2R)-7, 4'-dihydroxy-8-methylflavane (4), (2R)-7,4'-dihydroxy-5-methoxy-8-methylflavane(5),(2S)-7,3'-dihydroxy-4'-methoxy-8-methylflavane(6) ,(2S)-4',7-dihydroxy-6, 8-dimethylflavane(7), 4,2',4'-trihydroxychalcone(8), 4,4'-dihydroxy-2-methoxydihydrochalcon(9) and Cambodianin E (10). Antibacterial activity assay showed that compounds 1, 4 and 10 have inhibitory effect on Fusarium oxysporum f. sp. cuben, Fusarium oxysporum f. sp. niveum, Fusarium oxysporum f. sp. vasinfectum and Ralstonia solanacearum.

Objective To investigate the clinical efficacy of domestic porous tantalum rod in treatment of early avascular necrosis of femoral head (ANFH).Methods A prospective study was made on 18 cases (19 hips) diagnosed as early ANFH treated by domestic porous tantalum rod from July 2014 to December 2015.There were 14 males and four females, with a mean age of 44.2 years (range, 30-62 years).According to the modified Ficat staging, four cases were identified as stage Ⅱa and 14 stageⅡb.Efficacy of the treatment was evaluated by Harris score, Womac score, radiological images of the hip, complications and bone growth.Results All cases were followed up for 8-24 months (mean, 16 months).No complications such as infection, wound healing problems, immunological rejection, tantalum rod breakage, loosening or displacement were observed at last follow-up.Harris score was (82.7±9.0)points, (84.5±10.8)points and (87.2±10.0)points at postoperative 3, 6 and 12 months respectively, significantly higher than that pre-operation [(75.5±11.9)points] (P<0.05).Harris score was rated excellent in 10 cases, good in three, fair in five and poor in one at the last follow-up, with the excellent and good rate of 68%.Womac score was (17.4±9.4)points, (12.4±7.3)points, and (11.1±8.4)points at postoperative 3, 6 and 12 months respectively, significantly lower than that pre-operation [(28.3±13.1)points] (P<0.05).Seventeen cases (18 hips) showed no obvious deterioration in femoral head necrosis, with femoral head survival rate of 95%.One case underwent total hip arthroplasty after operation because of progressive hip pain and collapsed femoral head.Bone ingrowth was detected in the porous tantalum biomaterial after operation.Conclusion Domestic porous tantalum rod can effectively promote bone ingrowth, relieve pain, prevent the collapse of the femoral head, delay total hip arthroplasty time and finally improve hip function in treatment of early avascular necrosis of femoral head.
