Objective:To investigate the long-term toxicity of recombinant human interleukin-11(rhIL-11) in cynomolgus. Methods: Eighteen cynomolgus were randomized into 4 groups: control group(2/sex), low dose group(2/sex), medium dose group(2/sex)， and high dose group(3/sex). The drug groups were sc adminstered 0.1, 0.3 and 1.0 mg/kg of rhIL-11 for 90 days with a 30-day recovery period. The clinical signs were observed, electrocardiogram, hematological, biochemical, urinary and immunological parameters were measured, organ masses were weighed, bone marrow and pathological histology were observed. Results: The food consumption, body mass of the drug groups were decreased, the body temperature was increased transiently. One of the low dose group showed restricted movements and tremors. One of the high dose group vomited and another died. Reduced red blood cell(RBC) count, hemoglobin(Hb) concentration, hematocrit(Hct), mean corpuscular volume(MCV), mean corpuscular hemoglobin(MCH), and mean corpuscular hemoglobin concentration(MCHC), dose-related increase of platelet(Plat) counts were present in drug groups. Biochemical examinations revealed dose-related decreases in serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), lactate dehydrogenase(LDH), total proteins(TP) and albumin(Alb) increases in serum alkaline phosphatase(ALP) levels. Positive antibody responses were seen and circulatory immune complex(CIC) was significantly increased in all drug groups. Hypertropy of marrow megakaryocyocytes was noted in the medium and high dose groups. The heart and liver masses were slightly increased in all treatment groups. Treatment-related microscopic findings included dose-related degeneration in the liver and the kidney. The adverse effects were reversed by the end of the recovery period. Conclusion: The target organs and systems are blood, liver, kidney, immmue system and bone marrow. The toxicity injuries were reversible and the no-toxic-effect level is 0.1 mg/kg.

Objective To explore the impact and change regularity of Oncomelania hupensis snails and vegetation in the marshlands of Poyang Lake caused by the impoundment of the Three Gorges Project. Methods By using the methods of stratified systematic sampling and pinpoint navigation,the succession of vegetation was observed and the distribution of O. hupensis snails was investigated in a period of 8 years on 4 typical marshlands in Poyang Lake. The regularity of changes in vegetation and O. hu-pensis snails was analyzed on the marshlands at high,medium and low elevations,respectively. Results After the impoundment of Three Gorges Project,the average flooding days of these 4 marshlands in 2004 and in 2008 were reduced of 74.8 and 65.8 days compared with those in 2002,the year just before the impoundment of the project,respectively. The change of spatial distribution pattern and the succession of dominant species of vegetation on the marshlands of Poyang Lake have taken place since 2005,and several vegetations showed a trend of moving toward the center of the lake. The hygrophilous vegetation has degenerated and gradu-ally been replaced by mesophily meadow in the marshland area above 14 m elevation. Carex,Phalaris arundinacea and Polygo-num appeared in large area and expanded slowly towards the center of the lake on the marshland below 14 m elevation. O. hupensis snails were mostly found under the Carex association. The tendency of decreasing in density of snails and of migration of snail habi-tats towards low terrain was observed. Conclusions The impoundment of Three Gorges Project has had a significant impact on hy-drological regimes,and a new succession of vegetation has taken place in the marshlands of Poyang Lake. O. hupensis snails and the mesophily vegetation show a trend of migrating slowly to the areas of low elevation in the marshlands.

Objective To explore the relationship among genetic polymorphism of angiotension Ⅱ type 1 re-ceptor(AT1 R) A1166-C, angiotensin converting enzyme (ACE) insertion/deletion (I/D), aldosterone synthase (CYP11B2)-344T/C and hypertensive disorder complicating pregnancy.Methods Polymerase chain reaction-re-striction fragment length polymorphism (PCR-RFLP) assay was used to detect the genotypes of AT1 R A1166-C ,ACE (I/O) ,CYP11B2 -344T/C in 86 cases of hypertensive disorder complicating pregnancy and 175 cases of normal control.Results There was 18 combined types in hypertensive disorder complicating pregnancy cases and normal control cases.Compared to AT1R-AA + ACE-Ⅱ + CYP11B2-TT, Odds ratios (OR) of AT1R-AA + ACE-DO +CYP11B2-TC,AT1 R-AC + ACE-ID+CYP11B2-TC and AT1R-AC+ACE-DD+CYP11B2-TC are 7.289,5.315 and 5.694 respectively.There was no statistical significance among the others.Conclusion In all 18 kinds of combined types, AT1 R-AA + ACE-DO + CYP11B2-TC,AT1R-AC+ACE-ID+CYP11B2-TC and AT1 R-AC + ACE-DD +CYP11B2-TC might increase the susceptibility of hypertensive disorder complicating pregnancy.It is possible that multigenes are interacted in the etiology of hypertensive disorder complicating pregnancy.

Objevtive To investigate the safety of laparoscopic resection and ~(125)I seed implantation for recurrent gynecologic malignancies. Methods Laparoscopic surgery and ~(125)I seed implantation were used in five patients. All complications were recorded. Environmental radiation dose was detected at different distance from radioactive source and different time after operation with-γ-ray equipment. Results The procedure was safely achieved in all five patients. No serious complication was found. All patients experienced slight pain at the implant site and temporary vulva dropsy. With the increase of the distance from radioactive source and time passing, the radiation dose decreased quickly. The detected dose was close to a natural background radiation dose at the distance of 50cm from radioactive source and after 6 months. Conclusions Laparoscopic resection and ~(125)I seed implantation are safe to patient and environment.

Objective To study the expression characteristics of Let-7 genes in breast cancer.Methods Twenty-eight patients with breast cancer were randomly selected,and their cancer tissue and adjacent normal tissue were collected.TRIzol was used to extract the total RNA and real-time quantitative PCR was used to detect the relative gene expression levels.Results The expression of precursor Let-7 in cancer tissue was (9.65 ± 2.31),which was lower than that in normal tissue (10.05 ± 2.81),P =0.048.Precursor Let-7 had dependence relationship with the long menstruation (b =0.816,P =0.029).The menarche age showed a positive correlation with precursor Let-7 in normal tissue (r =0.502,P =0.048) and a negative correlation in cancer tissue (r =-0.484,P =0.049) Conclusions The expression of precursor Let-7 in cancer tissue is lower than that in normal tissue.The period of menstruation is a protective factor to breast cancer.

A rapid resolution liquid chromatography quadrupole time-of-flight mass spectrometric ( RRLC-QTOF/MS) method was used to profile the metabolites of urine samples from atherosclerosis ( AS) patients and healthy controls and find the differential metabolites which could provide the scientific evidence to explain the pathogenesis and early disease diagnose. In the study, 15 AS patients ( age46. 84±2. 41 years) and 15 healthy controls ( age45 . 72±1 . 93 years ) was screened out by VaSera VS-1000 . The urine samples were analyzed by RRLC-QTOF/MS and the resulting data matrices were analyzed by multivariate statistical analysis ( Principal Component Analysis, PCA ) to find the potential biomarkers. The results showed that the urine samples of AS patients were successfully distinguished from those of healthy controls. Besides, a total of two significantly changed metabolites, uric acid and Guanidineacetic acid, had been found and identified as potential biomarkers, which suggested that the disorder of purine metabolism and amino acid metabolism played an important role in the mechanism of AS.
