ABSTRACT
Objective To understand the quality status of salt iodine monitoring results at the county level and checking results at the city level from 2017 to 2021 in Suzhou，and to provide a scientific basis for the development of iodine deficiency disease（IDD）prevention and control strategies and measures. Methods During the past five years, Suzhou CDC randomly selected 15 samples of 300 monitored salt samples from each county/district CDC each year for spot checks. The data were processed by comparative analysis of relative error and grouped data t test. Results In the conformity of iodized salt and non-iodized salt, the sample monitoring results of some counties/districts were non-iodized salt, while the city-level test results were iodized salt. In the conformity of iodized salt and seaweed iodized salt (or enhanced salt), the sample monitoring results of county/district level were iodized salt, while the test results at the city level were seaweed iodized salt (or enhanced salt). The non-conformity was relatively concentrated in some county/district laboratories, and the total amount of non-conformity tended to increase year by year. The total number of samples with relative error of >20% between the county/district and city-level results was the least in 2021, with 6, and the most in 2018, with 25. The number of samples with relative error of >30% between the county/district and city-level results was the least in 2017 being 0, while there were 12 samples in 2018, fluctuating within a small range in the past three years. The t-test results of grouped data showed that the average value of the checking results at the city level was generally higher than the monitoring results at the county level. There were 21 pairs of data with no statistical significance (P>0.05) and 29 pairs of data with statistical significance (P<0.05) between the results at the county/district level and at the city level. Among them, there were 7 counties/districts whose sample monitoring results were not significantly different from the city-level test results in 2020, while there were 9 counties/districts whose monitoring results were statistically different from the city-level test results in 2021. Conclusion The data analysis results show that the monitoring data of iodized salt in Suzhou is basically reliable and accurate, but there still exist some problems. Therefore, in the future work it is necessary to strengthen the monitoring system of IDD, increase training efforts, continuously monitor and check the quality of iodized salt to provide a scientific basis for effective prevention and control of IDD.
ABSTRACT
Accumulating evidence suggest that microRNAs play crucial roles in the development and progression of bladder cancer(BC). Here, we found that miR-212-3p was significantly down-regulated and negatively correlated with nuclear factor IA(NFIA) in human BC tissues. Bioinformatics analysis predicted that NFIA was a target gene of miR-212-3p. Then BC celllines, T24 and J82 cells were transfected with miR-212-3p mimics or siNFIA to obtain miR-212-3p overexpression or NFIAknockdown cell lines, respectively. Quantitative real-time PCR was used to determine the expression of miR-212-3p andNFIA. Western blot analysis was utilized to detect NFIA expression. MTT assay showed either miR-212-3 overexpression orNFIA knockdown significantly inhibited the BC cell proliferation. Double staining with Annexin V-APC and 7-AAD showedthe total number of apoptotic BC cells were remarkably increased after miR-212-3p overexpression or NFIA knockdown.Collectively, our results indicated that miR-212-3p targeting NFIA might serve as a promising target for BC.
ABSTRACT
Colorectal cancer (CRC) is one of the most common malignant tumors.Accumulating evidences suggests that gut microbiota play an important role in CRC initiation and progression.Chinese herbal medicine has certain regulation effects on disorders of gut microbiota.In current review,we discuss the changes of gut microbiota in CRC patients,and summarize the effects of gut microbiota on CRC progression and their underlying mechanisms through barrier function,inflammation,bacterial enzymes,toxic metabolites,as well as the effects of Chinese herbal medicine on gut microbiota.This review provides a basic scientific and clinical application of gut microbiota in CRC.
ABSTRACT
Objective To observe the expressions of serum insulin-like growth factor (IGF)- Ⅰ ,Ⅱ and IGF binding protein (IGFBP) 3, 5 and to explore the clinical significances in patients with clear cell carcinoma of kidney. Methods Enzyme-linked immunosorbent assay (ELISA) methods were adopted to examine serum expressions of IGF-Ⅰ , Ⅱ and IGFBP 3, 5 in 40 cases with clear cell carcinoma of kidney (renal carcinoma group) and 16 cases with hydronephrosis (control group) from May 2007 to December 2009. Results IGF- Ⅰ , Ⅱ and IGFBP 3,5 in renal carcinoma showed higher expressions before operation (985. 7 μg/L, 1154.0 μg/L,46.6 μg/L and 9.6 μg/L, respectively)than after operation (431.4 μg/L, 632.6 μg/L, 26.7 μg/L, and 6.7 μg/L, respectively, all P＜0. 05 ～0.01). There were no significant differences in those indexes between pre- and post- operation in control group (P＞ 0. 05). Conclusions There are high expressions of serum IGF-Ⅰ , Ⅱ and IGFBP 3, 5 in renal carcinoma patients, and IGF- Ⅱ has clinical significance in diagnosis.
