Objective To explore the association of serum bilirubin level at the time of admission with the compos?ite outcome(disability or death)in discharged patients with acute ischemic stroke. Methods In a retrospective cohortstudy from June 1st 2009 to May 31st 2012, we continuously included 3151 patients with acute ischemic stroke and col?lected demography,lifestyle,clinical manifestations and laboratory test data. Functional outcome was measured with themodified Rankin scale (mRS) when subjects were discharged. Disability was defined as mRS≥3 and composite outcomewas defined as mRS≥3 or death. Serum bilirubin was divided into four groups according to the quartile. Multiple Coxregression analysis was used to assess the independent relation between serum bilirubin and disability death and the com?posite outcome. Results There were 407 disabled patients,the disability rate was 12.9%;and 104 patients were dead,the fatality rate was 3.3%.After adjusting for multiple factors, we found the risks of composite outcome with total bilirubin in the four quartile were higher than that in the first quartile, aHR and 95%CI were 1.335(1.047~1.702) respectively;The risks of composite outcome with indirect bilirubin in the four quartile were higher than that in the first quartile, aHR and 95%CI were 1.355(1.062~1.728) respectively; The risks of composite outcome with bilirubin direct in the third and the forth quartile were higher than that in the first quartile, aHR and 95% CI were11.403(1.089~1.807)and 1.431 (1.118~1.833) respectively.With the increase of total bilirubin,indirect bilirubin and direct bilirubin level,the compos?ite outcome of discharged patient was on the increase. Conclusions The study indicated that higher serum bilirubincould increase the risk of composite outcome in ischemic stroke patients, there was dose-response relationship ,and bili?rubin was a independent risk factor.

OBJECTIVETo observe clinical effect of integrated Chinese medical (CM) treatment (as maintenance therapy) on the progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small-cell lung cancer (NSCLC) after first-line chemotherapy.
METHODSThe study was a prospective, randomized, controlled clinical trial. Totally 69 non-progressive advanced NSCLC patients treated with first-line chemotherapy were randomly assigned to the test group (34 cases) and the control group (35 cases). Patients in the control group were treated with one Western drug chemotherapy (Gemcitabine or Alimta or docetaxel). Those in the test group were treated with integrated CM treatment (CM decoction, CM Intravenous preparation, and point application). Each cycle consisted of 21 days. Treatment lasted till the disease progressed, or intolerable toxic/adverse reactions occurred, or patients refused to continue the treatment. Patients' life spans were regularly followed-up.
RESULTS(1) The median cycle of maintenance therapy was 2 cycles for two groups with no statistical difference (P =0.274). The median PFS was 12.43 weeks in the test group and 10.00 weeks in the control group, showing statistical difference (P =0.025). The middle survival time (MST) was 18.8 months in the test group and 16.73 months in the control group, showing no statistical difference (P =0.437).
CONCLUSIONCM treatment (as maintenance therapy) showed quail effect to one Western drug chemotherapy in prolonging patients' life span.

Targeting induced local lesions in genomes (TILLING) is a reverse genetics method for functional genomics research.It is possible to screen for point mutations in the populations of EMS mutagenesis with highthroughput and lowcost. EcoTILLING a method based on TILLING ,was developed for detecting multiple types of polymorphisms in germplasm collections,such as single nucleotide polymorphism,small deletion and insertion etc.Rice is a very important food crop and a model plant for genome research also. There are complete genome sequence and a lot of other bioinformatics resources about it.So the markerassisted breeding is becoming more and more important in rice breeding. Some issues based on TILLING about identifying germplasm based on gene sequence,EMS mutagenesis breeding,developing functional marker in rice breeding in future were discussed.
