Objective:To study the relationship among serum uric acid (SUA)level,brachial-ankle pulse wave veloci-ty (baPWV)and severity of coronary disease.Methods:A total of 121 inpatients,who hospitalized in our depart-ment of cardiology from Jan 2011 to Jul 2012,were enrolled.According to results of coronary angiography,they were divided into coronary heart disease (CHD)group (n=59)and normal control group (n=62),CHD group was further divided into single vessel coronary disease group (n=30,single vessel group),double-vessel coronary disease group (n=14,double-vessel group)and multi-vessel coronary disease group (n=15,multi-vessel group).SUA level and baPWV were compared among all groups,and their relationship with degree of coronary disease was analyzed. Results:SUA concentration gradually rose along with number of diseased coronary vessels increased,it's (349.26± 96.58)μmol/L,(400.37±70.96)μmol/L,(517.57±85.26)μmol/L and (602.60±77.03)μmol/L in normal con-trol,single vessel,double-vessel and multi-vessel group respectively,P<0.05 or <0.01;baPWV gradually rose a-long with number of diseased coronary vessels increased,compared with normal control group,there was significant increase in baPWV [(1499.04±193.82)cm/s vs.(1885.32±319.73)cm/s,(2036.00±406.40)cm/s,(2171.03± 348.53)cm/s]in single vessel,double-vessel and multi-vessel group,that of double-vessel group was significantly higher than that of single vessel group,P<0.05~<0.01.Logistic regression analysis indicated that SUA and baP-WV were independent risk factors for CHD morbidity (OR=13.011,14.008,P=0.000).Conclusion:Serum uric acid level and pulse wave velocity possess important clinical application value for predicting CHD and its severity.

Objective To study the clinical effect of Xingnaojing injection in treating patients with acute cer-ebral infarction and its influence on serum matrix metalloproteinase 9 (MMP -9),nitric oxide (NO)and nitric oxide synthase (NOS).Methods 112 patients with acute cerebral infarction were randomly divided into two groups by ran-dom number table method,56 cases in each group.The control group received routine treatment for acute cerebral infarction.The observation group received routine treatment plus intravenous injection Xingnaojing.The changes of NIHSS score,motor function score and sensory function score in the two groups were compared before and after treat-ment.The serum levels of MMP -9,NOS and NO in the two groups were observed before and after treatment.Results The total effective rate of observation group was 82.14%,which was significantly higher than 64.29% in the control group (χ2 =4.553,P <0.05).After treatment,NIHSS scores of the observation group were significantly lower than the control group (t =5.082,5.522,6.253,all P <0.01 ).After treatment for 3 weeks,the motor function score (69.54 ±17.82)points,sensory function score (30.58 ±7.94)points of the observation group were significantly higher than (52.93 ±14.66)points and (23.08 ±6.31)points in the control group (t =5.387,5.534,all P <0.01).After treatment,the serum MMP -9,NOS,NO levels of the observation group were significantly lower than the control group (all P <0.01 ).Conclusion Xingnaojing injection in the treatment of acute cerebral infarction has good curative effect,it can promote the recovery of neurological function,improve motor function and sensory function, and by adjusting the MMP -9,NOS,NO levels to protect the nerve and blood vessel function.

Background and purpose:The screening of the genes being related closely with the mechanism of osteosarcoma metastasis was a difficult point in the realm of orthopaedics.We screened differential expression gene of human osteosarcoma MG-63 cell sublines with different metastatic capabilities with cDNA microarray,and studied the molecular mechanism of osteosarcoma metastasis.Methods:Total RNA of human osteosarcoma MG-63 cell sublines A1 and A2 was extracted,purified to mRNA and then reversely transcripted to cDNA probe respectively.The cDNA probe of A1 was labelled with Cy3 and the cDNA probe of A2 was labelled with Cy5.The two samples were hybridized with the cDNA microarray.The hybridization signals were scanned by Agilent Scanner and obtained data were analyzed using Ima Gene 3.0 software and Genespring software.Results:222 differential expression genes were found between cell sublines A1 and A2 by analyzing gene expression profile.There were 119 upregulated genes and 103 downregulated genes in cell sublines A1.All differential expression genes belonged to six main function groups and 49 genes of these had very obvious differentce in expression.Conclusions:There were many differently expressed genes between A1 and A2 cell sublines and only part of them were closely associated with mechanism of osteosarcoma metastasis.The technology of cDNA microarray could analyze effectively gene expression profile of human osteosarcoma MG-63 cell sublines, and supply a new approach to study the mechanism of osteosarcoma metastasis

Objective To investigate the clinical features of anuria caused by pediatric congenital bilateral ureteral stenotic obstruction,and to improve the diagnosis and treatment of the disease.Methods This series included 7 infants(2 males and 5 females;age range,35-57 d) with congenital bilateral ureteral stenotic obstruction.The clinical presentations were characterized by sudden anuria or oliguria.B-ultrasound,cystography and puncture pyelography were performed in all of them,and magnetic resonance urography(MRU) in 3.Based on the definite diagnosis,resection of stenotic segment of the ureter or ureteral implantation was performed on them.Results The diagnosis was confirmed by puncture pyelography in all of the 7 cases.Six cases underwent phase I surgery and recovered.No ureteral stenosis and cystoureteral reflux occurred during a follow-up of 2-4 years.The renal function was normalized in them.One case had stenosis recurrence due to scar formation,and was cured by the second operation.Conclusions Anuria caused by pediatric congenital bilateral ureteral stenosis should be diagnosed and treated as early as possible.Definite diagnosis can be established by puncture pyelography and MRU.Resection of the obstructive segment of the ureter,protection of renal function,and ureteral implantation are the main therapies.

Chemotherapy is one of the main treatments for gastric cancer, but its drug resistance often limits the effectiveness of chemotherapy, leading to treatment failure. Drug resistance can be divided into primary drug resistance and secondary resistance. It has showed that several factors were involved in the multidrug resistance of gastric cancer, including the expression of drug resistance-related proteins, abnormalities of apoptosis-related genes, dysfunction of DNA damage repair, epithelial-mesenchymal transition and non-coding RNA. The solution to improve the efficacy of chemotherapy is to overcome drug resistance or delay drug resistance. This article will explore the progress in multi-drug resistance of gastric cancer.
