Objective To study the role of HMGA2 in the occurrence and the progression of uterine leiomyomas.Methods Fifty cases of uterine leiomyomas who met the inclusion criteria(aged 30-50 years old,free from hormone at least for 6 months before surgery,no other diseases,postoperative pathological diagnosis as uterine leiomyoma) admitted to our hospital from January to July 2003 were studied.The expression of HMGA2 mRNA in uterine leiomyomas and neighbour normal myometrium was detected by ISH.Results HMGA2 mRNA was strongly expressed in 30 cases of uterine leiomyomas but not expressed in neighbour normal myometrium.There was no difference in HMGA2 mRNA between proliferative stage and progestational stage.Conclusion The increased expression of HMGA2 in uterine leiomyomas may be important in the occurrence and the progression of uterine leiomyomas.

Purpose To screen and identify T cell lymphoma invasion and metastasis 1 (Tiam1) related genes and expression profile during distant metastasis of colorectal cancer. Methods Colorectal cancer( CRC) in a mice model was established by intraperitoneal injection of dimethylhydrazine ( DMH) . Five panels of fresh primary tumor tissues from Tiam1 transgenic mice were collected and com-pared with that from wild type mice. Differentially expressed genes were detected by Affymetrix human genome-wide expression profile chip and verified by real-time quantitative PCR ( qRT-PCR) analysis. Results The genechip result showed that 794 genes were differ-entially expressed by at least 3 folds in Tiam1 transgenic mice with distant metastasis of colorectal cancer tissue, including 400 up-regu-lated and 394 down-regulated ones. Bioinformatics analysis and gene co-expression network building identified 3 genes (PIK3R5, FIGF and RPS6KA6) with specific expression in colorectal cancer tissue with distant metastasis, and this result was confirmed by qRT-PCR. Conclusion A specific Tiam1 gene expression profile related to colorectal cancer distant metastasis has been established through screening and identifying the genes related to Tiam1 by gene chip technique. These findings provide a basis for exploring the molecular markers of colorectal cancer with distant metastasis.

ObjectiveTo explore changes of serum adiponectin and insulin resistance in patients with endometrial cancer and to evaluate the clinical significance and correlation.MethodsThe serum levels ofadiponectinandfastinginsulinweredeterminedbyELISA, electro-chemilluminometryand radioimmunoassay in 35 patients with endometrial cancer [ all patients divided into two groups,A1 group belonged to without postmenopausal when first visiting (n =20),A2 group belonged to postmenopausal when first visiting (n ＝ 15 ) ] and 30 cases of health control.The result of homeostasis nodel assessment-insulin resistance (HOMA-IR) index was calculated.ResultsThe levels of adiponectin in A1 group was lower than that ofhealth control group [(6.7±1.1) versus (10.0 ±1.4) ng/L,P＜0.05],and HOMA-IR was higher than that of health control group ( 3.5 ± 1.8 versus 1.1 ± 0.7,P ＜ 0.05 ).While there were not significant difference between A2 group and health control group (P ＞ 0.05 ).Adiponectin and insulin resistance was negatively correlated ( r =- 0.389,P ＜ 0.05 ).Conclusion Adiponectin reducing and insulin resistance in reproductive age patients may be the independent factors to promote endometrial cancers.

Objective To explore the effect of Tiam1 overexpression on the biological behaviors of human colorectal cancer cells ( CRC ) . Methods The human CRC lines under the established stable overexpression of Tiam1 were studied. Cell morphology was detected before and after transfection by commassie blue staining and scanning electron microscope. The proliferation in vitro of CRC was tested by cell cycle, MTT and plate colony formation assay, the migration and invasion ability of CRC was tested by Transwell assay. The proliferation ability in vivo was studied by induced subcutaneous tumors of nude mice. Results Compared with HT29/mock cells, HT29/Tiam1 cells formed as spindle, the pseudopodia increased and elongated. The proportion in S phase of HT29/Tiam1 was higher (t=19.546, P=0.000), the proliferation ability enhanced (F=177.125, P=0.000), colonies formation ratio increased ( t = 3 . 222 , P = 0 . 032 ) . The number of HT29/Tiam1 cells acrossing the microporous membrane (t = 4.832, P=0.001)and Matrigel(t=3.779, P = 0.005)all raised. On the fifteenth day, the growth deference between the HT29/Tiam1cells and HT29/mock cells in nude mice in vivo occurred. Till the thirtieth day, the size of the tumors in HT29/Tiam1 cell group were 2.3 times as large as that in HT29/mock cell group (F=53.040, P=0.002). Conclusions Tiam1 stable overexpression can promote the proliferation, migration and invasion ability of CRC which indicates its important role in carcinogenesis and evolution of colorectal cancer. Tiam1 may represent a new therapeutic target for colorectal cancer.

Objective To summarize the expression of CK19, HBME-land 34βE12 in papillary carcinoma of the thyroid (PCT) and their differential diagnostic value. Methods Clinical data of papillary carcinoma of the thyroid,nodular goiter and paraeareinoma were reviewed. All HE slides were reexamined and immunostains for CK19, HBME-land 34βEI2 were performed in selected case. Staining results were evaluated. Results Those cases typically showed complex papillary structures and interstitial fibrosis, while nuclear features included ground class appearance, grooves and nuclear pseudoinelusion. The positive rates for CKI9, HBME-1 and 34βE12 in PCT were 100.0 %, 89.4 % and 42.6 % respectively, the differences were statistically significant(P <0.01). Conclusion PCT occurs preferentially in the group of middle-aged women. The diagnosis of PCT should be distinguished from other plesiomorphous benign papillary lesions. Combined detection of CK19, HBME-1, 34βE12 can be most helpful for diagnosis for of PCT.

Objective:To compare the volatile chemical constituents from the shell and kernel of Caesalpinia minax Hance.Methods:The volatile chemical compositions of Caesalpinia minax Hance were obtained by organic solvent-wet distillation and were analyzed by GC-MS equipped with a elastic quartz capillary column HP-5MS 5%Phenyl Methyl Siloxane(30m?0.25mm?0.25?m).The constituents were identified by their mass spectra.The relative percentage of the volatile constituents was calculated from the GC peak areas.Results:One hundred and fifteen kinds of chemical constituents in the shell of Caesalpinia minax Hance were separated and sixty-three of them,which accounts for 54.7%of total volatile constituents, were characterized.There are five kinds whose relative contents were more than 2.0%.One hundred and two kinds of chemical constituents in the kernel of Caesalpinia minax Hance were separated and fifty-one of them,which accounts for 50.0%,were characterized.There are seven kinds whose relative contents were more than 2.0%.Form the shell and kernel of Caesalpinia minax Hance there were forty kinds of chemical constituents the same.The most relative contents were Limonene(5.31%,shell)and 1-Hexanol(12.94%,kernel).Conclusion:This paper reports,for the first time,the comparison of volatile constituents from shell and kernel of Caesalpinia minax Hance.It is helpful for controlling the quality and further researching of Caesalpinia minax Hance.

Obiective:To establish a new and better model to investigate the properties of mast cells that couldbe involved in acupuncture process mechanisms.Methods:Connective tissue under the conum at the area of acupuncture point Zusanli(ST 36)from rat was acutely bluntly separated with forceps and scissors。And incubated in bath solution up to several hours.Mast cells in slices of that tissue were irradiated with laser light of 650 mn,and changes in the appearance were observed under mlcroscope. In addition.patch.clamp technique in whole-cell configuration was employed to induce mechano-sensitive currents by pressure applied through the patch pipette.Results:1)A high density of mast cells embedded in the extracellular matrix was detected in the tissue slices using toluidine blue staining.The mast cells survived for up to several hours;2)Laser irradiation for 10 min(40 mW) resulted in fusion of intracellular vesicles with the plasma membrane of the mast-cell surface;3)Whole.cell currents increased when pressure gradients of-30 cm,-60 cm or-90 cm H20 were applied,the response was attenuated in the presence of 1 0 u M Ruthenium Red(a common blocker of channels 0f the vallinoid.sensitive transient receptor potential family TRPV).Conclusion:The skin tissue slice of rat Zusanli(ST 36)may be used as a model to investigate the role of mast cells in acupuncture.t he results obtained in this model support the suggestion that skin mast cells play a role In laser as well as mechanical acupuncture and TRPV channels may be involved in acupuncture effects.

Purpose:To explore the relationship between genetic polymorphisms of p53 codon72 and the risk of gastric cancer.Methods:A population based case control study was conducted in Taixing, Jiangsu Province, China, and 204 gastric cancer cases and 415 controls were collected. Results:Distribution of Pro/Pro genotype in cancer cases was significantly higher than controls. The OR and 95%CI of Pro/Pro or Pro/Arg genotype was 1.5 (1.01～2.23) compared with Arg/Arg genotype. Pro/Pro or Pro/Arg genotype may interact with cigarette smoking, alcohol drinking, river water drinking and high salt food intake. Conclusions:Pro genotype may be related with the risk of gastric cancer and may also interact with environmental risk factors to increase the risk of gastric cancer.

Objective To examine the association between residual renal function at initiation of dialysis and prognosis in maintenance dialysis patients.Methods Incident patients with end-stage renal diseases initiating dialysis between 1 January 2005 and 30 September 2009,followed up to 31 March 2010 were enrolled in this study.Residual renal function was evaluated using eGFR estimated by the abbreviated MDRD equation.Patients were classified into four groups according to eGFR of ≥10.5,8 to ＜10.5,6 to ＜8,＜6 ml·min-1·(1.73 m2)-1.The outcome was all-cause and cardiocerebral vascular mortality.Results (1) A total of 562 patients were included.The median eGFR at initiation of dialysis was 5.60 (2.26-12.62) ml·min-1·(1.73 m2)-1.The median follow-up time was 17 (0-58) months from initiation of dialysis and 141 patients died within this period.The median survival time was 45.48 (43.05-47.90) months.With eGFR declined,Scr,BUN,serum uric acid,serum prealbumin,phosphorus,calcium and phosphate product,iPTH,mean arterial pressure (MAP) at initiation of dialysis increased (P＜0.05),and hemoglobin,proportion of male,proportion of diabetes comorbidity,proportion of the Charlson comorbidity index ≥5 decreased (P＜0.05).Though there was no significant difference among the four groups,the proportion of left ventricular hypertrophy comorbidity increased when eGFR declined.(2) There was no significant difference of all-cause mortality among four groups using Kaplan-Meire survival curve.Cox regression model indicated no significant difference of all-cause mortality in levels of eGFR (HR=1.012,95％CI 0.961-1.065,P=0.654).Without patients died in the first 3 months,the multivariate Cox regression model indicated eGFR at initiation of dialysis was the protective factor to 1 year survival (HR=0.791,95％CI 0.669-0.935,P＜0.01).(3) The multivariate Cox regression model indicated the risk of overall and 1 year cardiocerebral vascular death decreased with eGFR at initiation of dialysis increased (HR=0.868,95％CI 0.777-0.971,P＜0.05; HR=0.937,95％CI 0.851-0.992,P＜0.05,respectively).(4) The multivariate Cox regression model indicated eGFR at initiation of dialysis was benefit to survival of patients treated by peritoneal dialysis,with all-cause death risk decreased by 10％ when eGFR increased by 1 ml·min-1·(1.73 m2)-1 (HR=0.90,95％CI 0.81-0.99,P＜0.05).In hemodialysis patients,Kaplan-Meire survival curve was significantly different among the four groups (Log-rank test,P=0.047); the survival of the group of 8 to ＜10.5 ml·min-1·(1.73 m2)-1 was lower as compared to the groups of 6 to ＜8 (Log-rank test,P=0.033) and ＜6 ml·min-1(1.73 m2)-1 (Log-rank test,P=0.005); but the multivariate Cox regression model indicated no relationship between survival and eGFR.In the subgroup of chronic glomerulonephritis as primary renal disease,the eGFR at initiation of dialysis was the benefit factor,with all-cause death risk decreased by 16.6％ (HR=0.834,95％CI 0.736-0.946,P＜0.01) and cardiocerebral vascular death risk decreased by 18.2％ (HR=0.818,95％CI 0.669-0.999,P＜0.05) when eGFR increased by 1 ml ·min-1 ·(1.73 m2)-1.In the subgroup of chronic glomerulonephritis treated by peritoneal dialysis,the all-cause death risk decreased by 32.1％ with eGFR increased by 1 ml·min 1·(1.73 m2)-1 (HR=0.679,95％CI 0.535-0.862,P＜0.01).Conclusions Early initiation of dialysis may not be associated with improved overall survival,but may reduce cardiocerebral vascular and 1 year all-cause mortality,improve the survival of chronic glomerulonephritis patients and peritoneal dialysis patients.
