ABSTRACT
Objective In order to understand the contamination status of food-borne pathogens in food in Nantong City, and to provide a scientific basis for food safety risk assessment and supervision. Methods The monitoring was performed according to the plan of food safety risk surveillance in Nantong City and the manual on monitoring microbes and its pathogenic factors in foodstuffs of Jiangsu Province. A total of 1025 food samples of 11 kinds were monitored from 2017 to 2020 for detecting of pathogenic bacteria such as Listeria monocytogenes, Salmonella, Vibrio parahaemolyticus, Bacillus cereus and Staphylococcus aureus, and the test results were summarized, analyzed and evaluated. Results A total of 142 pathogenic bacteria were detected, with a total positive rate of 13.85%. The detection rate was the highest in 2018 (25.65%), and the lowest in 2017 (4.98%). The highest detection rate was found in meat and meat products(25.38%), followed by aquatic products and animal products (17.92%), cooked rice and flour products around the school (14.29%), the detection rate of barreled drinking water was the lowest (2.86%). 170 strains of pathogenic bacteria were detected from 1025 samples. The higher positive rate was Bacillus cereus in the cooked rice flour products around the school, and 5 strains of Bacillus cereus were detected, with the detection rate was 14.29%. 18 strains of Staphylococcus aureus were detected in meat and meat products, and the detection rate was 13.85%; 70 Vibrio parahaemolyticus were detected in aquatic products, and the detection rate was 13.49%; 16 Listeria monocytogenes were detected in meat and meat products, and the detection rate was 12.31%. The positive rate of catering links is higher than that of circulation links, and the positive rate of urban areas is higher than that of rural areas. Conclusions Pathogenic bacteria were detected in different kinds of food, and the overall situation of food safety is stable. In the future, the monitoring scope will be expanded continuously, the monitoring continuity will be strengthened, the sampling quantity will be increased, the monitoring quality will be improved, the trend of food pollution change in the city shall be mastered in time, food safety warning shall be well done, and food safety education shall be strengthened for food practitioners, food pollution risk shall be reduced and food safety shall be effectively guaranteed.
ABSTRACT
Objective To investigate the dynamic changes and its significance of inflammatory factors in cervical secretions and prior cervical tissues after cervical conical resection.Methods Women who received prior cervical conization during December 2013 and December 2015 in this hospital were selected,then the cervical tissue and secretion were collected regular interval after the conization.The expression of tumor necrosis factor-α(TNF),interleukin 6 (IL-6) and high mobility group protein 1 (HMGB1) were quantitative detected and analyzed.The expression and infiltration of inflammatory cell were detected by HE and immunohistochemical staining.Results The expression of TNF-α,IL-6 and HMGB1 in cervical tissues and secretions increased gradually after priorcervical conization,which reached the peak at 1 to 2 weeks after priorcervical conization,and then gradually decreased,the differences were statistically significant when compared with the preoperative control group (P＜0.05).The inflammatory cell infiltration and the inflammatory response were most severe at 1st week after the conization.The expression of TNF-α,IL 6 and HMGB1 was at 1st week after the conization were significantly higher than that of the 4thweek group.Conclusion The cervical inflammatory were most severe after the prior cervical conization about 1-2weeks,and the hysterectomy should be avoided at this stage.
ABSTRACT
Objective To investigate the possible associations of two polymorphisms (5-HTTLPR and STin2VNTR)of the serotonin transporter gene with alcohol use disorders (AUD).Methods 281 AUD cases (AUDIT score≥ 10) and 277 healthy controls (AUDIT score ≤5) were recruited in this study.All participants were genotyped using the PCR technique.Results The frequency of the L-allele of the 5-HTTLPR was 39.01％,and the 10-allele of STin2VNTR was 8.42％ in this population,the allele frequencies of both polymorphisms were consistent with Asian normal populations.No significant association was observed between 5-HTTLPR and AUD,but the genotypic and allele frequencies of the STin2VNTR were significant different between two groups even after Bonferroni adjustment,the 12 repeat allele of the STin2VNTR was significantly associated with the risk effect for AUD.Haplotype analysis for those two polymorphisms revealed no association between 4 haplotype combinations and AUD.Conclusion There is no relationship between 5-HTTLPR and AUD.The STin2VNTR polymorphism of 5-HTT may play a role in the pathogenesis of AUD.
ABSTRACT
BACKGROUND:Nuclear factor-κB (NF-κB) is highly expressed in the degenerated intervertebral disc. The Herbal Compound formula Yaotu Granules for lumbar disc herniation has achieved good clinical results;however, the underlying mechanisms remain poorly understood. OBJECTIVE:To explore mechanisms underlying the effects of the drug serum of Yaotu Granules on NF-κB signaling pathway. METHODS:Eight New Zealand white rabbits were randomly divided into normal saline group, low-, middle-, and high-dose drug groups. Normal saline, 10, 20, and 40 mL of water decoction of Yaotu Granules were administered intragastrical y in the normal saline, low-, middle-, and high-dose drug groups for 7 days, respectively. The drug serum of Yaotu Granules was prepared using serum samples obtained from the common carotid artery at 2 hours after the last administration. Human nucleus pulposus cel s were maintained in DMEM containing 10%(v/v) drug serum for 24 hours. RESULTS AND CONCLUSION:The expression levels of interleukin (IL)-8, tumor necrosis factor (TNF)-α, p-P65, P50, IκB-α(the NF-κB inhibitor), and IκB kinaseβ(IKK-β) mRNA in human nucleus pulposus cel s in three drug serum groups were significantly decreased compared with the normal saline group;in addition, a similar change in the expression levels of p-P65, P50, IκB-α, and IKK-βprotein between groups were detected. Noticeably, the expression levels of IL-8, TNF-α, p-P65, P50, IκB-α, and IKK-βmRNA, as wel as the expression levels of p-P65, P50, IκB-α, and IKK-βprotein were gradual y decreased with the increased drug dose. Al these results suggest that the drug serum of Yaotu Granules can protect nucleus pulposus cel s and delay their degeneration through blocking NF-κB signaling pathway.
