Objective To investigate the relationship between ? catenin expression and colorectal adenoma with canceration. Methods The expression levels of ? catenin in 25 cases of normal colorectal mucosa (NCM), 42 cases of colorectal adenoma (CA), and 19 cases of colorectal adenoma with canceration (CAC) were detected by immunohistochemistry. Results ? catenin expression was detected on the cell membrane in normal colorectal mucosa. Reduced membrane expression, cytoplasmic and nuclear expression were detected in the colorectal adenoma and adenoma with canceration. The cytoplasmic and nuclear expression rate of ? catenin was 89.5% in colorectal adenoma with canceration, significantly higher than that in colorectal adenoma(42 9%, P

Objective To observe the effect of caffeic acid phenethyl ester (CAPE) on proliferation, cell cycle and apoptosis of human colorectal cancer cell line SW480.MethodsSW480 cells were treated with CAPE .The proliferative status of cells was measured by methabenzthiazuron (MTT) assay. Cell cycle was analyzed by flow cytometry (FCM) . Apoptosis was detected by FCM. The apoptosis cells were detected by TUNEL staining.ResultsCAPE inhibited growth of SW480 cells in a dose-dependent and time-dependent manner. Cell G_0/G_1 phase rate increased, S phase rate decreased and cell apoptosis rate increased after exposed to CAPE in a dose dependent manner (2.5, 5.0 and 10mg/L). Apoptosis cells increased after the treatment of CAPE.ConclusionsCAPE inhibits the proliferation and induces apoptosis in human colon cancer cell line SW480.The effect mechanism is related to arrest the cell cycle G_1 and induce cell apoptosis.

Objective: To investigate the mortality and probability of premature death due to cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases and their trends among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020, so as to provide insights into the development of the chronic disease control strategy. Methods: The data regarding the mortality of cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020 were captured from the Zhejiang Provincial Chronic Diseases Surveillance Information Management System, and the crude mortality, standardized mortality by the sixth population census data in Zhejiang Province in 2010 and probability of premature death for these four chronic diseases were estimated. The trends in mortality and probability of premature death were analyzed in Hangzhou City from 2005 to 2020 using average annual percent change (AAPC). Results: A total of 6 436 deaths occurred due to cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020. The crude and standardized mortality rates were 183.33/105 and 152.88/105, which both appeared a tendency towards a decline from 2005 to 2020 (AAPC=-1.099% and -2.926%, both P<0.05), and the probability of premature death reduced from 10.40% in 2005 to 6.78% in 2020, which appeared a tendency towards a decline (AAPC=-2.827%, P<0.05). The probability of premature death due to malignant tumors, diabetes and cardio-cerebrovascular diseases all appeared a tendency towards a decline from 2005 to 2020 (AAPC=-2.681%, -6.571% and -2.286%, all P<0.05), while no significant changing trend was seen in the probability of premature death due to chronic respiratory diseases (AAPC=-4.263%, P>0.05). The probability of premature death for these four chronic diseases reduced from 13.55% in 2005 to 9.36% in 2020 among male residents (AAPC=-2.150%, P<0.05), and reduced from 7.18% in 2005 to 4.22% in 2020 among female residents (AAPC=-4.149%, P<0.05). Conclusions The mortality and probability of premature death due to chronic diseases appeared a tendency towards a decline in Xiacheng District, Hangzhou City from 2005 to 2020, and there was a significant decline in the probability of premature death for malignant tumors, cardio-cerebrovascular diseases and diabetes.

Objective To study the effects of caffeic acid phenethyl ester (CAPE) on the expression of β-catenin, c-myc and cyclin D1 in colorectal cancer cell line SW480. Methods The changes of mRNA and protein expression of β-catenin, cyclin DI and c-myc were detected by RT-PCR and Western blot after culturing the colorectal cancer cell line SW400 with different concentrations of CAPE (2.5, 5.0, 10.0 mg/L) for 24 hours and 48 hours. Results After the treatment of CAPE, the mRNA expression of β-catenin, cyclin D1 and c-myc were decreased from 1.05±0. 26, 0.87±0.09, 0.63 ± 0. 09 to 0.67 ±0. 10, 0.51±0.14, 0.32±0.14, respectively, and the protein expression of β-catenin, cyclin D1 and c-myc were decreased from 204±52, 111±11, 87±7 to 52±16, 52±16, 32±12, respectively. There was a significant difference in the decrease of mRNA and protein expression of β-catenin, cyclin D1 and c-myc in colorectal cancer cell line SW480 with and without treatment of CAPE (F=5.724, 6.793, 7.026, 15.936, 14.889, 14.162, 31.147, 28.881, 6.322, 17.647, 9.584, P<0.05 ). The inhibition effect of CAPE was displayed in a dose- and time-dependent manner. Conclusions CAPE can obstruct the β-catenin pathway, and down-regulate the transcription and expression of β-catenin, cyclin D1 and c-myc. The anti-tumor effect of CAPE may be related to the decreased expression of β-catenin, cyclin DI and c-myc.

Objective To evaluate the value of high frequency color Doppler ultrasound in detecting the growth of orthotopic prostate tumor in nude mice. Methods Thirty-five orthotopic prostate tumor models of BALB/c nude mice were established. High frequency color Doppler ultrasound was used to monitor the growth of tumors in five randomly selected BALB/c nude mice after 2 - 8 weeks. After examination,the nude mice were immediately sacrificed under narcotism. The tumors were dissected, fixed and embedded. The sections were stained by HE and reviewed under microscope as the gold standard of detecting the growth of orthotopic prostate tumors. The growth curves were recorded and analyzed. Results High frequency color Doppler ultrasound can be used to observe the size, resonance, blood supply and necrosis of tumors. The tumors grew fastest in 4～6 weeks after injection. After seven weeks, necrosis can be found in the center of the tumors while the boundary of the tumor was not clear. Conclusions High frequency color Doppler ultrasound can be a reliable method to monitor the growth of orthotopic prostate tumor in BALB/c nude mice.
