It has been indicated that the oncogene and anti-oncogene are closely related to the development and progression of cancer.With the development of molecular biology,detection of oncogene and anti-oncogene has become an important approach for clinical warning and diagnosing of cancer.Since the establishment of the molecular model of colon cancer by Fearon and Vogelstein in 1990,the genetics of colorectal cancer has gained major advances in early diagnosis.Early detection of related gene mutations is helpful for the early warning of colorectal cancer,especially for palients with hereditary cancer(the detection rate is fairly high).This review summarizes the progression of study on biomarkers of colorectal cancer.

OBJECTIVE:To investigate clinical efficacy and safety of breviscapine combined with vinpocetine in the treatment of acute cerebral infraction. METHODS:A total of 80 patients with acute cerebral infraction were selected from our hospital during Jan. 2014-Dec. 2015,and then divided into observation group and control group according to random number table,with 40 cases in each group. Control group was given Vinpocetine injection 20 mL+0.9％ Sodium chloride injection 250 mL,ivgtt,qd. Observa-tion group was additionally given Breviscapine injection 20 mL+5％ Glucose injection 250 mL,ivgtt,qd,at intervals of 2-3 h on the basis of control group. Both groups were treated for 2 weeks. Clinical efficacies as well as serum copeptin,NT-proBNP,albu-min cobalt binding(ACB)value,European stroke scale(ESS)and functional independence measurement(FIM)score before and after treatment were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:Total response rate of observation group(90.0％)was significantly higher than that of control group(67.5％),with statistical significance(P<0.05). Before treat-ment,there was no statistical significance in serum peptide,NT-proBNP,ACB value,ESS or FIM score between 2 groups (P>0.05). After treatment,serum copeptin and NT-proBNP levels of 2 groups were decreased significantly,while ACB value,ESS and FIM score were increased significantly;the improvement of observation group was significantly better than that of control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Breviscapine combined with vinpocetine can improve neurological function of acute cerebral infraction patients and show good therapeutic efficacy with good safety.

Objective To evaluate the association of body weight with brachial-ankle pulse wave velocity (baPWV) in females.Methods A total of 2 921 residents (≥20 years old) were selected by the stratified cluster random sampling method from March to December 2011.Arterial stiffness was assessed by baPWV.Multivariate logistic regression analysis was used to evaluate the effect of body mass index (BMI) on arteriosclerosis.The predictive value of BMI to evaluate arteriosclerosis was analyzed by using receiver operation characteristic (ROC) curve.Results The prevalence of arteriosclerosis was significantly increased in overweight/obese residents (P＜0.01).BMI was positively correlated with baPWV (r=0.310,P＜0.01).The prevalence of increased arterial stiffness in individuals≥65 years older was higher than that in people of 20-40 or 41-64 years old (x2 values were 677.30 and 347.26,respectively; both P＜0.01).For females of 20-40 or 41-46 years old,the prevalences of increased arterial stiffness in overweight and obese groups were higher than those in normal body weight group (both P＜0.01).In univariate analysis,age,resting heart rate,systolic blood pressure (SBP) and diastolic blood pressure (DBP) were correlated with arteriosclerosis (all P＜0.01).The odds ratio for the prevalence of arteriosclerosis in overweight women was 2.017 (95％ confidence interval (CI):1.637-2.486,P＜0.01) and that in obese women was 2.759 (95％ CI:1.964-3.876,P＜0.01) after adjustment for age,resting heart rate and blood pressure.The area under the ROC curve was 0.693 (95％ CI:0.671-0.715,P＜0.01) to evaluate arteriosclerosis in females and the optimal cut-off point for BMI was 23.42 kg/m2.Conclusions For females,overweight and obesity may be risk factors of arteriosclerosis.The optimal cut-off point for BMI to evaluate arteriosclerosis in women could be 23.42 kg/m2.

Objective To analyze diagnostic experience of children with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and assess its surgical results.Methods Six children with ALCAPA had been diagnosed in our hospital from Mar. 2006 to Oct.2007 aged from 6 months to 10 years old(median 43.5 months).The medical data included common clinical presentations,the findings of electrocardiogram(ECG),the echocardiogram,ECG-gated 64-slice computed tomography,the digital subtraction angiogram (DSA),surgical records and the outcome.Results Diaphoresis,fantod,breathlessness and difficult feeding were commonly presented in 5 cases ALCAPA and the 5 children presented with left ventricular failure in infancy.The predominant ECG findings were Q waves and ST segment changes in the anterolateral chest leads in 4 cases,ST changes in 1 case,and normal ECG in 1 case.Cross-sectional echocardiography showed dilated left ventricles with poor contractility in 4 cases,medium mitral regurgitation in 2 cases and severe mitral regurgitation in 2 cases,aneurysmal dilatation of the right coronary artery(RCA) in 2 cases.CT and DSA examinations showed characteristic changes in these children.The surgical reestablishment of a two-coronary system was performed in 5 cases,direct reimplantation in 2 cases and creation of an autologous extrapulmonary tunnel in 3 cases.Simultaneous mitral annuloplasty was performed in 2 cases.After operation,the symptoms of 5 cases were all improved and none died.Conclusions Understanding the clinical manifestations and lab findings of ALCAPA is helpful to making an early diagnosis of ALCAPA.Early surgical treatment can improve the patients′ outcome.

Objective To study the association between serum prolactin(PRL)level,prolactin receptor(PRLR)expression on peripheral blood mononuclear cells and the disease activity in the patients with systemic lupus erythematosus(SLE).Methods Serum PRL level was measured by time-resolved fluoroimmunoassay(TrFIA)in113patients of SLE and in28gender-and-age matched control subjects,SLEDAI index was estimated.It was also investigated by logistic multiple regression analysis that the association between clinical manifestations,immunologic parameters,anti-dsDNA antibody titers and hyperprolactinemia in113patients of SLE.The specific binding(SB)rate of peripheral blood lymphocyte PRLR was measured by radioactive binding ligand assay(RLBA)and the mRNA expression of PRLR by reverse transcription polymerase chain reaction(RT-PCR)in24active SLE patients,22inactive SLE patients and15gender-and-age matched control subjects.Results The serum PRL levels of63active patients were much higher than those of50inactive patients and28control subjects.The serum PRL levels ranged9~51.2?g/L in79.3%of active patients.It was also found that PRL level was in positive linear correlation with the titer of anti-dsDNA antibody.The concentration of interleukin2receptors in hyperprolactinemia group was higher than that in normal group.It was shown that proteinuria,low levels of complement3and high titers of anti-dsDNA antibody were associated with hyperprolactinemia by logistic multiple regression analysis.The SB rate of PRL receptor was5.03?2.51%(x?s),the total binding rate(TB)was15.4?6.98%in24active patients with SLE.The SB rate of active patients was much higher than that of22inactive patients(SB4.18?2.26%,TB rate14.03?6.54%)and that of15gender-and-age matched control subjects(SB1.62?1.05%,TB8.19?1.47%).The mRNA expression of PRLR in active patients(x?s,0.85?0.45)was much higher than in inactive patients(0.58?0.43)and that in control subjects(0.20?0.13).Conclusion The slightly increased serum level of PRL,high expression of PRLR and the increased specific binding rate are associated with the disease activity of SLE.

objective To investigate the ability of insulin sensitivity index HOMA2-%S and secretion function index HOMA2-%B calculated by HOMA2,the new homeostasis model assessment,in clinical application. Methods Eighty female volunteers with polycystic ovary syndrome in Chongqing area [50 subjects with normal glucose tolerance(NGT group)and 30 subjects with impaired glucose regulation(IGR group)]were involved in this study.Thev underwent a 75 g oral glucose tolerance test(OGTF)and the Botnia clamp test. From the data of faming blood samples in OGTF,insulin sensitivity index HOMAI-ISI,secretion function index HOMAl-β and disposal index DI-HOMA1 were calculated by the old homeostasis model assessment(HOMA I),meanwhile insulin sensitivity index HOMA2-%S,secretion function index HOMA2-%B and disposal index(DI-HOMA2) were caleulated by the new homeostasis model assessment (HOMA2).Correlation coefficients between insulin sensitivity index and GIR (the glucose infusion rate at steady state of Botnia clamp test),and between insulin secretion function index and AIR(the acute insulin response in Botnia clamp test),were studied.Results The Pearson's linear correlation coefficient between HOMA2-%S and GIR(r=0.503),HOMA1-ISI and HOMA2-%S (r= 0.990).HOMA2-%B and AIR(r=0.382),HOMA1-B and HOMA2-%B(r=0.976) were all statistically significant(a11 P<0.01).The glucose disposal indexes calculated from the HOMA2 and HOMA1 of 1GR group were significantly lower than those from the NGT group(t=2.825,P<0.Ol;t=2.222,P<0.05). Conclusion The HOMA2 is a better model in evaluating the insulin sensitivity and secretion function and is recommended to be widely used in clinical evaluation.

Objective To purify and identif y Platanus acerifoli wild pollen. Methods We carried out intracutaneous test with Platanus pollen extract in 30 patients with allergic as thma who visited our hospital from March to May 2003. Seven subjects who had bee n diagnosed as having Platanus pollen-induced asthma were enrolled. Platanus po llen proteins were separated by gel filtration with Sephadex-G-100. To charact erize allergenic components, Platanus pollen extract was analyzed by means of so dium dodecylsulfate-polyacrylamide gel electrophoresis followed by immunoblotti ng. Results To purity the pollen we separated Platanus poll en extract in a first purification step by using gel filtration with Sephadex G -100. Two elution peaks were observed. Twelve percent SDS-PAGE analysis showed more than 10 protein bands whose molecular mass (Mr) ranged from 16 ku to 71 ku. Six bands abundant with protein at 71, 50, 35, 39, 22 and 16 ku were observed. On SDS-PAGE, the proteins of the first peak whose Mr we re 71, 50, 35, 39, and 22 ku and that of the second peak was 16 ku. SDS-PAGE and IgG-immunoblotting analysis with seven sera showed 4 IgG-binding component s whose Mr was 50, 39, 22 and 16 ku. The protein bands whose Mr was 50 ku and 22 ku had the highest binding capacity. Conclusion The strongest activity exists in the first peak which can be the major sensiti zing components and there is mild allergic activity in the second peak which is the minor sensitizing components.
