BACKGROUND: Animal experiments demonstrated that adding ultraviolet blood irradiation and oxygenation (UBIO) in cardioplegic solutions has myocardial protection during cardiopulmonary bypass (CPB).OBJECTIVE: To investigate the myocardial protective effect of UBIO as cardiac arresting solution in the process of CPB in old patients undergoing valve replacement.DESIGN, TIME AND SETTING: The randomized controlled trial of biochemistry level was performed at Department of Cardiac Surgery, Guizhou Provincial People's Hospital, from October 2006 to April 2008.PARTICIPANTS: A total of 46 old patients scheduled for heart valve replacement were randomly divided into test group and control group, with 23 patients in each group.METHODS: The test group was infuoed with the UBIO blood as a cardiac arresting solution via the ascending aorta. The UBIO blood accumulated from the subclavian vein (10 mL/kg) was heparinized and dealt with the ultraviolet irradiation (wave length 240-300 nm) and oxygenation. And then it was infused for the first antegrade coronary perfusion when the ascending aorta was cross-clamped, when the UBIO blood was produced, the equivalent quantitative saline was infused from another vein. The 4:1 cold oxygenated blood hyperhalemia cardioplegia was perfused and then maintained for 30 minutes. The control group was the same as the test group except that the cardiac arresting solution presented without the 4:1 cold oxygenated blood.MAIN OUTCOME MEASURES: Blood samples were withdrawn from coronary venous sinus before cross-clamping and at minutes 5 and 10 after aorta declamping, to measure the levels of superoxide dismutase (SOD) and the content of malondialdehyde (MDA). Before the beginning of CPB, and at hours 4, 24, and 48 after the end of CPB, venous blood was drawn to test the serum cardiac troponin I(cTnI) and creatine kinase isozyme (CK-MB).RESULTS: MDA levels of plasma were less in the test group than that of the control group after aorta declamping (P < 0.05),while the SOD activity was obvious greater than the control group (P < 0.05). At hours 4-48 after CPB, CK-MB and cTnl levels were lower in the test group than the control group (P< 0.05).CONCLUSION: Antegrade coronary first perfusion with UBIO during CPB has evident cardiac protective in old patients undergoing valve replacement by elevating SOD activity, decreasing MDA level, relieving myocardial reperfusion injury, as well as decreasing myocardial damage markers levels.

Objective To investigate the influence of indomethacin to the unite treatment effect on chronic phase myeloid leukemia (CML-CP) with interferon alpha-2b (IFNα-2b) and low dose cytarabine (LD-Ara-C).Methods 22 CML-CP patients were randomly divided into two groups.Control groups (10 cases) injected with IFNα-2b (3 million units),injection frequency was q.o.d,the duration of treatment was about 3-18 months,cytarabine (Ara-C) by slowly intravenous driped (30 mg/d).In this treatment schedule,every course of treatment sustained 10 days,and with a 2 weeks interval.During this process,patients in treatment group were treated with hydroxyl urea only when their WBC in peripheral blood exceed 20×109/L,otherwise,discontinue it.Treatment group (12 cases),on the first day of treatment with IFNα-2b and Ara-C,added indomethacin (25 mg) through oral administration,the frequency was t.i.d.During treatment in the two group,the end point of observation was completely hematology ease,at the same time,these indicators in the two groups needed to be compared,the time when WBC begin to fall,the time when WBC fall to normal range,the time when immature cells returned to normal,the time which complete hematological remission and the highest temperature of patients after IFNα-2b was subcutaneous injected.Results The time when WBC begin to fall in treatment group was (4.2±2.7) d,and the time was (5.0±2.5) d in control group (t =0.714,P ＞ 0.05).In treatment group,the time when WBC fall to normal range was(10.0±4.5) d,and the time was (12.0±4.5) d in control group (t =1.036,P ＞ 0.05).The time when immature cells returned to normal in treatment group was (14.2±4.8) d,and the time was (19.0±3.6) d in control group (t =2.609,P ＜ 0.02).The time which complete hematological remission was achieved in control group was (45.8±5.6) d,but it was (53.9±10.5) d in control group (t =2.314,· P ＜ 0.05).Meanwhile,the fever degree after IFNα-2b was subcutaneous injected obviously achieved improvement in treatment group (x2 =12.041,P ＜ 0.005).Conclusion The advantage of indomethacin to the unite treatment with IFNα-2b and LD-Ara-C on CML mainly lays in which cound alleviated the adverse reaction such as flu-like of IFN,and more,there are synergy effect in antagonist CML.

Objective To investigate clinical efficacy and safety of endoscopic multiband mucosec-tomy(EMBM)for esophageal submucosal tumors(SMTs).Methods Data of 51 patients with SMTs diag-nosed between Jan 2012 and Aug 2014 were retrospectively studied.Of the 51 patients,33 patients(34 le-sions)received EMBMand 18 patients received endoscopic submucosal resection(ESMR).The operation success rates,complete resection rates,procedure time,complications and the follow-up of group EMBMand group ESMR were compared.Results All of 51 cases had successful endoscopic treatment with no perfora-tion,infection or obvious bleeding.Follow-up showed no recurrence after operation.Compared with group ESMR,group EMBM had higher complete resection rate [97.1% (33 /34)VS 61.1% (11 /18 ),P =0.010],shorter operation time[(6.3 ±1.8)min VS (21.4 ±3.8)min,P =0.001]and lower complication rate[6.1%(2 /33)VS 27.8%(5 /18),P =0.024].Conclusion EMBM is simple,safe and effective for treating SMTs originating from muscularis mucosa or submucosa which are less than 2.0 cm in diameter.

Objective To evaluate the efficacy and safety of the unilateral and bilateral drainage in hilar malignant biliary obstruction with a meta?analysis of relevant studies. Methods A systematic electronic search with keywords “ biliary stent”, “hilar tumor” and “malignant biliary obstruction” was independently performed by two reviewers in major electronic databases of Pubmed, EMBASE, Cochrane Library and Web of Science. A meta?analysis was conducted using Revman 5?? 1 software. Results Six studies were included with a total number of 558 patients, of whom 307 patients underwent unilateral biliary drainage and 251 pa?tients bilateral drainage. There was no significant difference in early complications ( OR = 1?? 03,95% CI:0?? 58?1?? 81,P = 0?? 93), later complications (OR = 0?? 98,95%CI:0?? 46?2?? 07,P = 0?? 95), operation success rate (OR= 1?? 42,95%CI:0?? 76?2?? 66,P = 0?? 28),drainage efficacy or median survival time between the two groups. Compared with unilateral biliary drainage, bilateral biliary drainage had a longer time of stent patency (MD = - 29?? 12,95% CI:- 38?? 55?- 19?? 70,P< 0?? 001). Conclusion Both unilateral and bilateral biliary drainage are safe and effective for hilar malignant biliary obstruction, but more high quality clinical researches are needed.

To explore the effective ingredients and mechanism of Ligusticum wallichii in treating brain ischemia.

Action mechanism and material base of compound Danshen dripping pills in treatment of carotid atherosclerosis were discussed based on gene expression profile and molecular fingerprint in this paper. First, gene expression profiles of atherosclerotic carotid artery tissues and histologically normal tissues in human body were collected, and were screened using significance analysis of microarray (SAM) to screen out differential gene expressions; then differential genes were analyzed by Gene Ontology (GO) analysis and KEGG pathway analysis; to avoid some genes with non-outstanding differential expression but biologically importance, Gene Set Enrichment Analysis (GSEA) were performed, and 7 chemical ingredients with higher negative enrichment score were obtained by Cmap method, implying that they could reversely regulate the gene expression profiles of pathological tissues; and last, based on the hypotheses that similar structures have similar activities, 336 ingredients of compound Danshen dripping pills were compared with 7 drug molecules in 2D molecular fingerprints method. The results showed that 147 differential genes including 60 up-regulated genes and 87 down regulated genes were screened out by SAM. And in GO analysis, Biological Process ( BP) is mainly concerned with biological adhesion, response to wounding and inflammatory response; Cellular Component (CC) is mainly concerned with extracellular region, extracellular space and plasma membrane; while Molecular Function (MF) is mainly concerned with antigen binding, metalloendopeptidase activity and peptide binding. KEGG pathway analysis is mainly concerned with JAK-STAT, RIG-I like receptor and PPAR signaling pathway. There were 10 compounds, such as hexadecane, with Tanimoto coefficients greater than 0.85, which implied that they may be the active ingredients (AIs) of compound Danshen dripping pills in treatment of carotid atherosclerosis (CAs). The present method can be applied to the research on material base and molecular action mechanism of TCM.

This study is to explore the effects of quercetin (QUE) on the 3 week-old mice ovarian development and relative hormone levels. The 3 week-old mice were exposed to QUE (45, 25, and 5 mg x kg(-1) x hd(-1)) by gavage for 50 days. The estrous cycle during 50 days and the changes of hormone level such as FSH, LH, etc were monitored. Moreover, the ovaries were removed after sacrifice. The organ index was measured, and the ratios of different stages of follicles were analyzed by HE staining. Furthermore, the proportion of PCNA positive cells during all stages was detected by immunohistochemistry. The results showed that QUE could increase body weight of mice and reduce the anogenital distance (AGD) to some extent, and was able to disrupt mice's estrous cycle, but it could not extend or reduce the cycle regularity. It increased ovarian organ index with a dose-dependent manner. The proportion of the primordial follicle and secondary follicles rose obviously, and that of mature follicles', atretic follicles' and corpus luteums' reduced, while primordial follicle had no change. Immunohistochemistry analysis showed that QUE could effectively increase the percentage of proliferating cells in all kinds of follicles. Serum hormone assay showed that there were significant changes of FSH and LH levels. In summary, QUE showed an estrogen-like effect on mice's ovarian development. The weight of ovary, the proportion of all kinds of follicles, the development of ovarian cells and the level of plasma hormone in mice were altered obviously by oral administration of QUE.

OBJECTIVETo investigate the effects of Biejia Ruangan Tablet ([symbol in text], BRT)-containing serum on the expression of matrix metalloproteinase (MMP-9) and tissue inhibitor of metalloproteinase (TIMP-1) in cultured renal interstitial fibroblasts.

METHODSDifferent BRT-containing sera were prepared by gastric gavages to rats with the high-dose (7 g/kg), mid-dose (3.5 g/kg), and low-dose (1.75 g/kg) BRT respectively. The expression of extracellular matrix in NRK-49F cells was induced by treatment with human transforming growth factor-β1 (recombined human TGF-β1), and BRT-containing serum. Western blotting and Northern blotting were used to measure type I and III procollagen, MMP-9, and TIMP-1.

RESULTSThe high dose BRT-containing serum could decrease the type I and III procollagen gene expression which boosted by TGF-β1, at the same time cut down TIMP-1 protein and gene expression which increased by TGF-β1 (P <0.05). Treatment of cells with recombined human TGF-β1 had no significant effect on MMP-9 expression and BRT-containing serum also had no effect on MMP-9 expression.

CONCLUSIONSHigh dose BRT has anti-fibrosis effects in NRK-49F cells, as indicated by its inhibition of type I and III procollagen and TIMP-1 expression.
