Objective:To investigate the acceptance and attitude toward a novel fecal immunochemical test (FIT) in colorectal cancer screening among populations in China.Methods:From May 2018 to May 2019, 2 474 people aged 50-74 years were recruited from five provinces of China (Zhejiang, Anhui, Jiangsu, Hunan and Yunnan). The general demographic characteristics, acceptance of the new FIT technology and operational difficulties through the whole screening process were obtained through questionnaire survey. Multivariate logistic regression model was used to analyze the factors related to difficulties encountered in sampling stool, reading and uploading results.Results:The subjects were (60.0±6.4) years old, and female, high school of above educated, unemployed/retired/other, married and with medical insurance status of “new rural cooperative medical care (NRCMC)” accounted for 61.7% (1 526), 29.0%(718), 34.3% (849), 92.7% (2 293) and 31.3%(775), respectively. The population's acceptance of the FIT technology was 94.8%. In the process of FIT screening, the percentage of occurred difficulties in sampling stool, reading and uploading results were 33.1% (819), 46.4% (1 147) and 62.9% (1 557), respectively. The main difficulties were the uncertainty about whether the sampling operation was standard (28.0%), the inability to accurately judge the result displayed (32.5%) and the need for help without using a smartphone (44.2%). The results of multivariate logistic regression model analysis showed that people aged 65-74 years old and with medical insurance status of “NRCMC” were more likely to encounter difficulties in sampling, and those who were unemployed/retired/other and living with 3 or more family members were less likely to encounter difficulties in sampling. Those aged 65-74 years old, farmers or migrant workers, and those with “NRCMC” were more likely to encounter difficulties in readingresults, and those with 3 or more family members were less likely to encounter difficulties in reading result. Those with “NRCMC” were more likely to encounter difficulties in uploading results, and those with education level of high school or above, living with more than 3 family members were less likely to encounter difficulties in uploading results.Conclusion:The acceptance of the new FIT technology is relatively high among the subjects. Age, education level, occupation, number of family members living together and medical insurance status might be related to difficulties encountered in sampling stool, reading and uploading results, and it can be further strengthened in terms of the technology and characteristics of sub-populations.

This paper introduces the technical features of hydrosurgery system and evaluates it from three aspects:safety and effectiveness, economy and technology maturity. The evaluation results show that the safety and effectiveness are high, and the safety mainly involves the misuse of the system, which cause the adverse events. A large number of literatures have proved that the system is more suitable for the debridement of fine parts. It is estimated that hydrosurgery system has better economic performance, but the cost and patients' cost is also increased correspondingly. In the aspect of technology maturity assessment, this technology is a patented technology, and the number of published papers both at home and abroad is on the rise, indicating that the initial application of the technology is better and the technology is in infancy stage. Therefore, hydrosurgery system has certain advantages in all aspects. Hospitals need to allocate the equipment according to their own needs and clinical application, while a wider range of clinical trials is needed to provide evidence-based evidence for clinical applications and promotion.

OBJECTIVE:To investigate the correlation of blood concentrations of tamoxifen (TAM) and its metabolites with endometrial hyperplasia in estrogen receptor(ER)-positive breast cancer patients. METHODS:A total of 69 patients with ER-posi-tive breast cancer selected from our hospital during Mar. 2015-Apr. 2016 received TAM (twice a day,one tablet each time) for more than 6 months. According to endometrial thickness,they were divided into abnormal hyperplasia group(40 cases)and normal group(29 cases). The steady state concentrations of TAM and its metabolites [4-OH-tamoxifen(OHT),N-demethylation tamoxifen (DMT),Endoxifen] were determined by HPLC-FLU. The correlation of blood concentration and other factors with endometrial thickness were investigated by Pearson test and multiple regression analysis. RESULTS:The medication time and Endoxifen steady state concentration in abnormal hyperplasia group were both significantly longer or higher than normal group,with statistical signifi-cance (P<0.05). There was no statistical significance in age,BMI,complication and steady state concentrations of TAM,OHT and DMT between 2 groups(P>0.05). The endometrial thickness was positively correlated with Endoxifen steady state concentra-tion and medication time(r=0.447,0.460,P<0.05). Using endometrial thickness(y)as dependent variable,medication time(x1) and Endoxifen steady state concentration(x2)as independent variable,multiple regression analysis was conducted. Multiple regres-sion equation was calculated as follows:y=2.436+0.123x1+0.082x2(F=12.610,r=0.526,P<0.05). CONCLUSIONS:Medication time and Endoxifen steady state concentration may be related to endometrial hyperplasia,which can provide reference for predicting TAM induced endometrial abnormal hyperplasia in ER-positive breast cancer patients.

Objective:To study the correlation between plasma concentration and clinical efficacy in newly diagnosed type 2 diabe-tes treated with nateglinide. Methods:On the basis of diet control and exercise, 73 cases of newly diagnosed type 2 diabetes received nateglinde therapy for 2 months. Adverse events were routinely monitored during the therapy. Fasting blood glucose(FBG), 2h post-prandial blood glucose(2h-PG), fasting C-peptide(F-CP), 2h C-peptide(P-CP) and glycosylated hemoglobin (HbA1c) were ob-served before and after the treatment. LC-MS was used to determine the plasma concentration of nateglinide on the last day of treat-ment. Results:FBG, 2h-PG, HbAlc and P-CP after the treatment had significant changes when compared with those before the treat-ment (P<0. 05). There was no significant difference in F-CP in spite of minor increase (P>0. 05). The difference in HbA1c and P-CP before and after the treatment both showed a significantly positive correlation with plasma concentration of nateglinide (P<0. 05). Conclusion:Nateglinide displays good clinical efficacy and safety in newly diagnosed type 2 diabetes, and its plasma concentration can be used to evaluate the pancreatic islets function and glucose-lowing effects.
