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.

Objective To analyze the findings of recurrent/residual caner after thyroidectomy for thyroid cancer in both ultrasonography (US) and contrast-enhanced CT (CECT),and to assess the diagnostic value of combination of these two modalities.Methods Forty-six patients with recurrence/ residue of thyroid cancer underwent both high-frequency US and CECT examinations and were enrolled in this study.The imaging features on US and CECT were reviewed and diagnostic accuracies for local residual lesions and cervical lymph node metastasis were evaluated according to pathological results.Results In 46 patients,the average period between thyroidectomy and diagnosis of recurrent/residual cancer was (14.6 ± 12.1) months(range,7 days-10 years).Twenty patients had local recurrent tumors at the surgical bed and the average size of tumors was 2.1 cm(range,0.5-4.6 cm).On US finding,the recurrent/residual tumors were hypoechoic in 60 ％ of cases,had microcalcification in 40 ％.Cervical lymph node metastasis were found in 40 patients,and 75％ of them were located in zone V[.The smallest size of abnormal lymph node which can be detected by US was 3 mm.In cases of lymph node metastasis,12 cases (30％) became cystic,10 (25 ％) presented microcalcifications,and 5 (12.5 ％) showed microcalcifications and cystic change within a lymph node.Microcalcifications,cystic change and hyperechoic appearance within a lymph node suggested malignant.The detection rate of US and CECT in the local recurrent/residual cancer were 90％ and 90％,respectively.The detection rate of cervical lymph nodes metastasis were 80 ％ and 72.5 ％,respectively.The diagnostic accuracy of US and CECT in local recurrence,cervical lymph node metastasis and both were 65％,67.5％ and 65.2％ vs 75％,55％ and 65.2％,respectively (P ＞ 0.05 for all comparisons).the diagnostic accuracy of combination of US and CECT were increased to 86.4％,77.5％ and 91.3％,respectively.US combined with CECT significantly improved the diagnostic capability compared with US or CECT alone(P ＜0.05).Conclusions US should be used as the first choice of imaging examination for post-thyroidectomy of thyroid cancer.US combined with CECT could further increase the diagnostic accuracy in recurrent/residual thyroid cancer.
