Objective To explore the efficient, cheaper and practical water treatment process in removing algae toxins. Methods The different water treatment methods were used and the optimal combination was selected. The removing efficiency for different processes was compared and validated by beaker test. The enzyme-linked immunosorbent assay (ELISA) was conducted in microcystin testing. Results Coagulating sedimentation could remove a small part of microcystin (removing efficiency was from 4.3% to 29.7% ). When oxidants were applied in pretreatment processes, such as ozone combined with coagulant, 83.3% to 91.9% microcystin could be removed. The cost-benefit analysis showed these processes only increased 0.03 to 0.14 yuan RMB cost per cubic meter of water, for example, by using ozone pretreatment and oxidation plus adsorption processes. Conclusion On the basis of general water treatment, ozone(O3), potassium permanganate(KMnO4), chlorine, dioxide(ClO2)and powdered activated carbon(PAC) are effective for removing microcystin in pretreatment processes and the processes are cheaper and practical.

Objective To investigate the expression of β-catenin and Oct-4 in colonal carcinoma and explore the relationship with recurrence and metastasis after operation. MethodsImmunohistochemical analysis was used to evaluate the expression of β-catenin and Oct-4.The correlation of β-catenin and Oct-4 expression with tumor cell differentiation,T stage,N stage and metastasis was analyzed.The gene expression of Oct-4 was examined by RT-PCR in 20 frozen tumor tissues and normal tissues adjacent to tumor.Results Thirty-five patients had metastasis. The positive rates of β-catenin and Oct-4 expression were significantly higher in metastasis group than in the non-metastasis group (65.71% vs 31.11%,51.43 %vs 13.33 %,x2 =9.843,P =0.002,x2 =13.605,P =0.001).Expression of β-catenin and Oct-4 was not associated with differentiation,T stage or N stage.The positive expression rate of Oct-4 in colonal carcinoma tissues was significantly higher than that in normal tissues.Metastatic rates in patients with positive expression of β-catenin and Oct-4 was higher than that in negative expression.The survival analysis showed that time of metastasis was significantly different in two groups of patients (P <0.05).Conclusion The expression of β-catenin and Oct-4 in tumor tissues is related to metastasis of colonal cancer after surgery and might be used to predict metastasis of colonal cancer after operation.

Objective:To evaluate the value of ultrasound-guided transperineal systematic prostate biopsy(SPB)and cognitive fusion multi-parameter magnetic resonance imaging(mpMRI) suspicious transperineal targeted biopsy(CFTB) in the prostate cancer with different serum prostate specific antigen(PSA) levels.Methods:A retrospective analyses were performed in 527 patients with suspected prostate cancer who underwent ultrasound-guided SPB from January 2018 to December 2019 in Shanghai Jiaotong University Affiliated 6th People′s Hospital. According to the PSA levels, they were divided into group A(PSA 4-10 μg/L) and group B(PSA>10 μg/L). All the patients underwent ultrasound-guided SPB, 376 patients with suspicious mpMRI had two additional targeted biopsies. The detection rates of ultrasound-guided SPB and CFTB in prostate cancer were tested by χ 2 test. Compared with pathological results, the sensitivity, specificity, accuracy of two methods were calculated and tested by χ 2 test, and a P<0.05 was defined as statistically significant difference. Results:Prostate cancer was detected in 319 of 527 patients(60.5%). One hundred and three cases of 198 patients in group A were diagnosed as prostate cancer, with an overall detection rate was 52.0%. Among them, ultrasound-guided SPB detected 72 cases of prostate cancer, the detection rate was 36.4%, sensitivity was 67.9%, specificity was 17.7%, accuracy was 26.5%, the detection rate, sensitivity, specificity and accuracy of CFTB were 39.9%, 75.6%, 91.6% and 88.8%, respectively. In this group, there were no statistically significant differences in the detection rate and sensitivity of the two methods in the diagnosis of prostate cancer (χ 2=0.525, 0.005, both P>0.05), and the differences in specificity and accuracy were statistically significant (χ 2=108.340, 79.829, respectively, both P<0.05). Two hundred and sixteen cases of 329 patients in group B were diagnosed as prostate cancer, with an overall detection rate was 65.7%. Among them, 160 cases of perineal prostate cancer were detected by ultrasound-guided SPB, with the detection rate was 48.6%, sensitivity was 78.2%, specificity was 37.6% and accuracy was 49.5%. A total of 189 cases of prostate cancer detected by CFTB, the detection rate was 57.4%, the sensitivity was 89.3%, the specificity was 90.6%, and the accuracy was 90.2%. All the differences were statistically significant in group B(χ 2=5.131, 4.391, 61.339, 38.982, all P<0.05). Conclusions:When PSA is greater than 10 μg/L, CFTB has a higher diagnostic efficiency than SPB.When PSA is 4-10 μg/L, there are no significant differences between the two methods in the detection rate and sensitivity of prostate cancer.

Background:Recent studies have shown that long non-coding RNAs(lncRNAs)play important roles in carcinogenesis and cancer biology and the related context has attracted more and more attentions. PVT1,which encodes a lncRNA,is reported to be up-regulated and exhibit pro-oncogenic activity in a wide variety of human cancers. Aims:To investigate the expression of PVT1 in human pancreatic cancer cells and its effect on proliferation and apoptosis of HPAF-Ⅱ cells. Methods:One target siRNA against PVT1 was synthesized and transfected into HPAF-Ⅱ cells by using lipofactamine technique. PVT1 mRNA expression was detected by real-time PCR;capability of cell proliferation was examined by MTS and colony formation assays;cell cycle progression and apoptosis were measured by flow cytometry;and Western blotting was performed to determine the expressions of apoptosis-related proteins and proto-oncogene protein c-Myc. Results:The mRNA expression of PVT1 in several human pancreatic cancer cell lines,especially HPAF-Ⅱ cells was significantly higher than that in H6c7,a human immortalization normal pancreatic ductal epithelial cell line. Compared with HPAF-Ⅱ cells transfected with negative control siRNA or without transfection,silencing of PVT1 by siRNA-PVT1 resulted in remarkable reduction in cell proliferation,cell cycle G1 phase arrest,and notable apoptosis;meanwhile,the expressions of apoptosis-related proteins(cleaved-caspase-3 and cleaved-PARP)were up-regulated,the ratio for Bcl-2 / Bax was decreased,and the expression of c-Myc protein was down-regulated. Conclusions:LncRNA-PVT1 is highly expressed in human pancreatic cancer cell line HPAF-Ⅱ. It may affect the proliferation and apoptosis of HPAF-Ⅱ cells partially through regulating c-Myc expression.
