ABSTRACT

Objective:To investigate the clinical features and prognosis of patients with pancreatic metastasis from clear cell renal cell carcinoma(CCRCC).Methods:From Jan 2000 to May 2020, the clinical data of patients pathologically diagnosed as CCRCC with pancreatic metastasis and admitted in Cancer Institute and Hospital of Tianjin Medical University were analyzed retrospectively. The gender, age, metastasis time, relapse time, metastatic sites, numbers of metastatic lesions and whether metastatic pancreatic lesions should be surgerically removed were recorded and the influencing factors were analyzed.Results:Among the 20 patients, there were 12 males and 8 females. The median age of diagnosis was 50 years. There were 12 patients(60%) of left renal carcinoma and 8 patients(40%)of the other side. 12 cases(60%) had single pancreatic metastatic lesion and the other 8 cases(40%) had multiple metastatic lesions. Seven patients(35%) had other organs metastasis besides pancreatic metastasis. Two patients(10%) had simultaneous pancreatic metastasis and renal cancer, and the other eighteen patients(90%) had pancreatic metachronous metastasis after being diagnosed as renal cancer. The median time from the diagnosis of CCRCC to pancreatic metastasis was 102 months. Thirteen patients(65%)had recurrences within 10 years and the other seven patients(35%)had recurrences after 10 years. Pancreatectomy was performed in nine patients(45%) and targeted therapy was conducted in thirteen patients. The mean follow-up was 122.9 months (1-256 months). Three patients (15%) died and 17 patients (85%) survived. The median overall survival was 75.9 months, and the 5 year-survival rate was 66.7%. Simultaneous metastasis and extra-pancreatic metastasis were prognostic factors in patients with CCRCC with pancreatic metastasis.Conclusions:Pancreatic metastases from renal clear cell carcinoma were rare, but the prognosis was good, especially in patients with only pancreatic metastases several years after renal carcinoma was diagnosed.

ABSTRACT

Objective: To investigate the survival and individualized therapy of metastatic colorectal cancer (mCRC) patients who achieved a stable disease state after induction chemotherapy. Methods:Data were reviewed from 204 metastatic colorectal cancer pa-tients, who presented a stable disease state after first-line and second-line chemotherapy at Tianjin Medical University Cancer Insti-tute and Hospital. The clinical and pathological characteristics were analyzed. Moreover, we analyzed the significance of maintenance treatment in patients with certain mCRC characteristics. Results:Univariate analysis indicated that the line of chemotherapy, levels of CA724, CEA, and CA19-9, and platelet-to-lymphocyte ratio (PLR) were considered prognostic factors of treatment after induction che-motherapy. According to the multivariate analysis, first-line chemotherapy, as well as low levels of CA19-9 and PLR, with maintenance treatment after the induction chemotherapy was significantly associated with better survival. Among the patients with high levels of PLR, those who underwent maintenance treatment achieved a progression-free survival of 13.43 months (versus 10.63 months in pa-tients from the observation group, P=0.003). Conclusion:The levels of CA19-9 and PLR, and treatment after chemotherapy were signif-icant prognostic factors for mCRC patients who achieved a stable disease state after induction chemotherapy. These patients, especial-ly those with high PLR, could benefit from the maintenance treatment.

ABSTRACT

Objective To obtain the expression pattern of imprint gene H19 in JEG-3 cell in order to explore the regulation mechanism of H19 on trophoblast cellular biological behavior .Methods After correct identification with sequencing for the recom-binant eukaryotic expression plasmid pRc/CMV which including the whole length of H19 cDNA ,the plasmid was transfected to the cell line JEG-3 .The expression of H19 mRNA was observed and the gene expression profile of three groups of JEG-3 cell were de-tected with Affymetri :U133 plus 2 .0 Array .Results After being transfected with target H 19 gene ,the expression of the mRNA level was significantly increased compared with control group .And the gene expression profile was changed significantly .19 genes were up-regulated ,77 genes were down-regulated .Expression levels of HES1 gene which being choosed as a different expression gene were detected by fluorescence quantitative PCR in severe preeclampsia placenta tissue and normal late pregnant placenta .The expression level of HES1 mRNA in severe preeclampsia placenta decreased significantly than normal late pregnant placenta tissues . Conclusion Many genes induced by H19 have been screened by high-throughput gene chip method .It provides the experimental ba-sis for advanced studying the regulation the cellular biological behavior with H 19 gene .

ABSTRACT

ObjectiveTo investigate the mechanism of dexamethasone (Dex) in inhibiting monocyte adhesion and phagocytose function.Methods Under the stimulation of phorbo1-12-myristate-13-acetate (PMA),U937 monocytes cultured in vitro were treated with Dex and Fasudil respectively.The adhesion rate of U937 monocles to human umbilical vein endothelial cells (HUVECs) and their phagocytic ability of India ink were studied.The protein content and activity of rho-associated coiled-coil protein kinase 1 ( ROCK1 ) as well as the effects of mifepristone and cycloheximide on Dex were determined.ResultsBoth DEX and Fasudil could significantly inhibit the adhesion tate and phagocytosis of U937 cells stimulated by PMA and suppressed the activity of ROCK1.While mifepristone and cycloheximide could not alter these effects of DEX.ConclusionDEX interferes with the adhesion and phagocytosis function of U937 cells by inhibiting ROCKI activity.

ABSTRACT

Objective To explore the role of H19 imprinting in etiology of pre-eclampsia. Methods Placentas of 24 women with pre-eclampsia (3 with mild pre-eclampsia and 21 with severe pre-eclampsia) and 50 healthy pregnant women at full term (control) were collected during selected cesarean delivery between August 2007 and March 2008. The statuses of H19 imprinting with placental tissues from normal pregnancy and patients with pre-eclampsia were identified upon polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The systolic and diastolic pressure were analyzed in H19 heterozygotic women. Results (1) There were 20 (40%) heterozygotes in 50 cases placenta tissues of the third trimesters, 11 (45%) heterozygotes in 24 cases placenta tissues of pre-eclampsia, There were no significant difference between two groups ( P > 0.05 ). (2) All 20 heterozygotes in placenta tissues of the third trimesters are exclusively monoallelically expressed, while 5 cases (45%) in 11 heterozygotes of pre-eclampsia are biallelically expressed (loss of imprinting, LOI). There were significant difference between two groups (P < 0. 01 ). (3) The values of systolic and diastolic pressure of patients with monoallelic expression of H19 were (171 ±9) mm Hg (1 nun Hg =0.133 kPa) and ( 104±8) mm Hg, the values of systolic and diastolic pressure with biallelic expression were ( 194±21 ) mm Hg and ( 124±18) mm Hg. There were significant difference between two groups (P<0.05 ). Conclusion LOI of H19 can be identified in pre-eclamptic placentas and is associated with maternal blood pressures, which implies the involvement of H19 gene LOI in the pathogenesis of pre-eclampsia and its potential relationship with the severity of the disease.

ABSTRACT

Objective To investigate the protecting mechanism of heat stress pretreatment on acute lung injury(ALI). Methods The oleic acid ALI mouse model was built to dynamically observe the binding capacity and the binding affinity of glucocorticoid receptor(GR),the levels of GR,heat shock protein 90(Hsp90)and Hsp70 before and after hyperthermic stress pretreatment. Results Heat stress pretreatment had significant protective effect on ALI.Western blotting showed insignificant changes of GR levels but progressive increase of level of Hsp70 and Hsp90.Heat stress pretreatment exerted insignificant effect on Bmax and Kd of GR,shown by radio ligand binding assay after ALI. Conclusion The protective effects of heat stress pretreatment on ALI of mouse may relate to its ability of keeping stable GR level and increasing levels of Hsp70 and Hsp90.
