The paper is to systematically evaluate the efficacy and safety of Deng Zhan Xi Xin injection ( DZXXI) as an adjuvant treatment for patients with angina pectoris. The Cochrane Library, Medline, EMbase, CBM, CNKI, VIP, and Wan fang Data base were searched. Randomized controlled trials (RCTs) of DZXXI combined with western medicine routine treatment versus western medicine routine treatment alone for angina pectoris patients were all included. All trials were assessed according to the Cochrane Reviewer' s Handbook 5.1 for Systematic Reviews of Intervention and Meta analyses were performed by RevMan 5. 2 Software. A total of 30RCTs (3 086 patients including 1 572 patients of treatment group and 1 514 patients of control group) were included. Meta-analysis of treatment group compared with control group showed superior effect over reducing cardiovascular events ( OR = 0.33; 95% CI: [0.16, 0.67], P = 0.002, improving effective rate of DZXXI as adjuvant treatment for angina pectoris patients (OR = 3.97; 95% CI: [3.15, 5.02]; P < 0.000 010 and electrocardiogram curative effect (OR = 2.21; 95% CI; [1.83, 2.68]; P < 0.000 010. Funnel figure seemed that there was publication bias. The current limited evidence showed that when compared with the control group, treatment group was superior in improving patients with angina pectoris. But based on the limitations of the study, rigorous design with long follow up clinical trials are necessary for further evidence.

18 fungal strains including N.coenophialum,N.lolii, N.huerfanum、N.chisosum、N.aotearoae、N.sp.and 8 varieties of grass seeds belonging to Festuca arundinacea and Lolium perenne have been studied.With amplification of IS1～IS3 and F1～R1 of genomic DNA, the primers Tub-2-F～Tub-2-R from Tubulin-2 gene and F3～R3 from NC25 gene have been designed.A PCR method to detect N.coenophialum and N.lolii was established, and also a nested-PCR method to detect N.coenophialum and N.lolii in single seed was established.These PCR detection methods are strongly special and much credible and rapid-speeded.

AIM:To analyze the characteristics of optical coherence tomography ( OCT ) in diabetic optic neuropathy ( DON ) retrospectively.
●METHODS:Retrospective study. A total of 175 cases of type ll diabetes with fundus lesions from Dec. 2013 to Dec. 2015 were selected and the clinical information was collected. These cases were diagnosed by consultation between Departments of Ophthalmology and Endocrinology in the Second Affiliated Hospital of Xi′an Jiao Tong University. The results of body examination were recorded and cases were examined by color fundus photography, fluorescein fundus angiography ( FFA) and OCT. All these data were analyzed.
●RESULTS: A total of 49 cases ( 90 eyes, 25. 7%) were diagnosed DON through FFA which manifested abnormal fluorescence in optic papilla. Results of OCT showed:among 90 eyes of DON patients, 15 eyes ( 16. 7%) had normal optic nerve form; 20 eyes(22. 2%) of excavation of optic disc became smaller or disappeared, with prelaminar tissue and peripapillary retinal nerve fiber layer (RNFL) swelling;26 eyes (28. 9%) manifested optic cup deep and cup/disc ratio increasing;18 eyes (20. 0%) had tissue hyperplasia in the hollow or on the surface of optic disc; 11 eyes(12. 3%) had symptoms including vitreous traction optic papilla and optic disc rim rising. DON eyes which had similar fluorescence features could manifest different tissue morph by OCT.
●CONCLUSION: FFA defines DON by change of blood circulation in optic nerve. However, OCT can show differences of tissue morph of optic nerve that FFA fails to do. So OCT can manifest the causes and sites of optic neuropathy more clearly and also provide basis for treatment. The advantages of OCT are conducive to reviews and curative effect tracking among DON patients and these advantages including noninvasive, convenient, inexpensive and repeatable.

Seven compounds were isolated from Onychium japonicum by macroporous resin, silica gel, ODS, Sephadex LH-20 column chromatography and semi-preparative HPLC. Their structures were identified by NMR, MS and other spectroscopic methods as onychone A (1), quercetin (2), quercetin-3-O-α-L-rhamnoside (3), kaempferol-7-O-β-D-glucopyranoside (4), kaempferol-3-O-α-L-rhamnopyranoside (5), (-)-prunin (6), and norathyriol (7). Compound 1 is a novel macrocyclic flavonoid, and all the others are reported from this plant for the first time. In vitro cytotoxic activities of compounds 1-7 were evaluated by MTS testing with five cancer cell lines. Compound 7 exhibited weak cytotoxicity against tumor cell lines A549, SMMC-7721, and SW480.

In this study, we investigated the pharmacokinetics parameters of SPIO-shRNA dual functional molecular probe and observed the main organ distribution by MRI in vivo. Eighteen New Zealand white rabbits were randomly divided into three groups and injected intravenously with different doses of SPIO-shRNA molecular probe, respectively. The blood samples were collected to analyze the pharmacokinetic parameters by measuring the iron content at 30 minutes before and after the injection. Twenty-four Kun Ming (KM) mice were randomly divided into 4 groups: the control group was injected intravenously with physiological saline 200 µL per mouse via the tail vein, the other 3 groups were injected intravenously with different doses of SPIO-shRNA molecular probe. MRI observation was performed in 24 hours, and the liver, spleen, kidney, brain and muscle were collected for iron quantification with Prussian blue staining to determine distribution of the SPIO-shRNA molecular probe in the main organ in vivo. Our results suggest that the molecular probe blood half-life is more than 3 hours. The data of MRI suggest the probe was distributed in liver and spleen, and the MRI signal was reduced with the increase in probe's doses (P < 0.05). The results of Prussian blue staining confirmed the results of MRI. Most of the probe could escape the phagocytosis of mononuclear phagocyte system. Our data provide the pharmacokinetic and distribution of SPIO-shRNA molecular probe in organs. Meanwhile, it suggests the choice of the time and dose of probe for MR imaging of tumor in vivo.

OBJECTIVETo explore the distribution characteristics of basic syndromes and its related factors in patients with chronic functional constipation (CFC).

METHODSThe complete data of 538 patients with CFC were collected and initial database was established with Epidata 3. 0. TCM syndrome typing was performed. The distribution characteristics of basic syndromes were analyzed using SPSS 17. 0 Software. The univariate and multivariate Logistic regression analyses were performed with SPSS 17. 0 Software to determine basic syndrome related factors such as age, engaged professionals, sleep quality, depression, mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation, and so on.

RESULTSThe TCM syndrome frequency of CFC patients was sequenced from high to low as qi deficiency syndrome (380 cases, 70.6%), qi stagnation syndrome (337 cases, 62.6%), blood deficiency syndrome (234 cases, 43.5%), yin deficiency syndrome (220 cases, 40.9%), yang deficiency syndrome (197 cases, 36.6%), and others(58 cases, 10. 8%) . Most patients were complicated with complex syndromes, and the most common complex syndromes were qi deficiency complicated qi stagnation syndrome (275 cases, 51.1%) and qi deficiency complicated blood deficiency syndrome (222 cases, 41.3%). Aging, work fatigue, and exercise conditions were main related factors for qi deficiency syndrome (P <0. 01, P <0. 05). Poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, defecation barriers constipation were main related factors for qi stagnation syndrome (P <0.01). Sleep quality and poor emotional (depression and anxiety tendencies) were main related factors for blood deficiency syndrome (P <0. 01, P < 0.05). Stimulating beverages were main related factor for yin deficiency syndrome (P <0.05). Engaged in mental work and slow transit constipation were main related factors for yang deficiency syndrome (P < 0. 01, P <0. 05).

CONCLUSIONSCFC is featured as complex syndromes. The most common complex syndromes were qi deficiency complicated qi stagnation syndrome and qi deficiency complicated blood deficiency syndrome. Basic syndrome related factors such as age, engaged professionals, sleep quality, poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation were associated with the distribution of CFC syndromes.

OBJECTIVETo evaluate the effect of astragalus (As) on cytokines in patients undergoing heart valve replacement (HVR).

METHODSThirty patients undergoing HVR were randomized into the As group and the control group. Cardiopulmonary bypass (CPB) was set up routinely and to the As group, As injection (40 mL, 10 mL containing 2 g of crude drug) was added into the prime solution just before CPB. Blood samples were collected at different time points during and after CPB for cytokines determination, including tumor necrosis factor alpha (TNF-alpha), interleukin-6 (IL-6), IL-8 and IL-10 by ELISA.

RESULTSAll the indexes measured were insignificantly different between groups before skin incision, they began to increase by the end of CPB (P < 0.05), reached the peak 3 h after CPB and then decreased gradually, TNF-alpha returned to the baseline level 24 h after operation. Meanwhile, levels of IL-6, IL-8 and IL-10 decreased obviously but still above the baseline. Comparisons between groups at different time points showed that levels of IL-6 were not different significantly (P > 0.05), those of IL-10 were higher at all time points, and TNF-alpha and IL-8 at 3 h, 6 h and 12 h after CPB were significantly lower in the As group (all P < 0.05).

CONCLUSIONAstragalus may decrease the inflammation cytokine promoting factors, and increase the level of anti-inflammatory cytokine (IL-10), so it could attenuate the inflammation reaction in patients after HVR.

Background/Aims: Anti-reflux mucosal ablation (ARMA) is a promising endoscopic intervention for proton pump inhibitor (PPI)-dependent gastroesophageal reflux disease (GERD). However, the effect of ARMA on esophageal motility remains unclear. Methods: Twenty patients with PPI-dependent GERD receiving ARMA were prospectively enrolled. Comprehensive self-report symptom questionnaires, endoscopy, 24-hour impedance-pH monitoring, and high-resolution impedance manometry were performed and analyzed before and 3 months after ARMA. Results: All ARMA procedures were performed successfully. Symptom scores, including GerdQ (11.16 ± 2.67 to 9.11 ± 2.64, P = 0.026) and reflux symptom index (11.63 ± 5.62 to 6.11 ± 3.86, P = 0.001), improved significantly, while 13 patients (65%) reported discontinuation of PPI. Total acid exposure time (5.84 ± 4.63% to 2.83 ± 3.41%, P = 0.024) and number of reflux episodes (73.05 ± 19.34 to 37.55 ± 22.71, P < 0.001) decreased significantly after ARMA. Improved esophagogastric junction (EGJ) barrier function, including increased lower esophageal sphincter resting pressure (13.89 ± 10.78 mmHg to 21.68 ± 11.5 mmHg, P = 0.034), 4-second integrated relaxation pressure (5.75 ± 6.42 mmHg to 9.99 ± 5.89 mmHg, P = 0.020), and EGJ-contractile integral(16.42 ± 16.93 mmHg · cm to 31.95 ± 21.25 mmHg · cm, P = 0.016), were observed. Esophageal body contractility also increased significantly (distal contractile integral, 966.85 ± 845.84 mmHg · s · cm to 1198.8 ± 811.74 mmHg · s · cm, P = 0.023). Patients with symptom improvement had better pre-AMRA esophageal body contractility. Conclusions ARMA effectively improves symptoms and reflux burden, EGJ barrier function, and esophageal body contractility in patients with PPIdependent GERD during short-term evaluation. Longer follow-up to clarify the sustainability of ARMA is needed.
