Objective To understand the prevalence of Toxoplasma gondii infection and related factors among special popu?lation in Changzhou City,so as to provide the evidence for formulating toxoplasmosis prevention measures. Methods The ve?nous blood was collected from participants in Changzhou City for detecting IgG and IgM antibodies against T. gondii by ELISA;and an epidemiological questionnaire investigation was also conducted. Results Among the total 400 respondents detected,the prevalence of T. gondii infection was 15.0%and the positive rates of IgG and IgM were 15.0%and 0.8%,respectively. The T. gondii infection rates of pregnant women,HIV/AIDS patients,patients with neoplasia,and livestock and poultry breeding and processing workers were 11.0%,11.0%,24.0%and 14.0%,respectively. As the age increased,the infection rate of T. gondii showed an upward trend,with the highest infection rate(21.6%)among the group of respondents aged above 50 years. The in?fection rates of groups with different education levels were statistically different(χ2=11.443,P<0.05),and there was a trend that the infection rate decreased with the increase of education level. The prevalence of T. gondii infection in pregnant women was not significantly associated with the number of pregnancies and gestational age. The infection rate of T. gondii in the live?stock and poultry breeding and processing workers increased with the length of their working years. Conclusions The preva?lence of T. gondii infection among the special population in Changzhou City is high. Therefore,it is necessary to enhance the health education on the knowledge and information of prevention and control of toxoplasmosis,and to improve the awareness of personal protection,the hygiene practices and diet habits. In addition,more attention should be paid to T. gondii monitoring in the special population.

Objective To investigate the prevalence of Toxoplasma gondii infection and related knowledge and behavior among special population in Changzhou City,so as to provide the evidence for formulating effective measures of toxoplasmosis prevention. Methods The pregnant women and patients with neoplasia in Changzhou hospitals,and livestock and poultry breeding or processing workers were selected as the subjects of the study. Venous blood samples were collected from each partici-pant for detecting IgG and IgM antibodies against T. gondii by ELISA. A questionnaire investigation on knowledge and behavior about T. gondii infection was conducted. Results Among the total 300 respondents investigated from March to May,2015,the prevalence of T. gondii infection was 16.3％(49/300). Totally 52 respondents knew the knowledge about the prevention and con-trol of T. gondii infection with an awareness rate of 17.3％(52/300). The proportion of participants who frequently contacted with cats/dogs(25.0％,13/52)in the group who knew the knowledge about the prevention and control of T. gondii infection was lower than that of participants(50.8％,126/248)in the group who did not know the knowledge about the prevention and control of T. gondii infection,and the difference was statistically significant(X2=11.51,P<0.05). The proportion of participants sepa-rating chopping boards for raw and cooked food(61.5％,32/52)in the group who knew the knowledge about the prevention and control of T. gondii infection was statistically higher than that of the participants(9.3％,23/248)in the group who did not know the knowledge about the prevention and control of T. gondii infection,and the difference was statistically significant (X2=78.43,P<0.001). There was a negative correlation between the awareness rate of the knowledge about the prevention and con-trol of T. gondii infection and the infection rate of T. gondii. The infection rate of T. gondii(5.8％,3/52)in the group who knew the knowledge about the prevention and control of T. gondii infection was lower than that(18.5％,46/248)of the group who did not know the knowledge about the prevention and control of T. gondii infection,and the difference was statistically significant (X2=5.14,P<0.05). Conclusions The awareness rate of the knowledge about the prevention and control of T. gondii infec-tion among special population in Changzhou City is low. The health education on the knowledge of the prevention and control of toxoplasmosis should be strengthened,in order to improve the awareness of personal hygiene and change the unhealthy lifestyles and dietary habits.

Searching for new antidiabetic lead compound, 4-(1-aryl-3-oxo-5-phenylpentylamino) benzenesulfonamides were designed and synthesized directly by three component one-pot condensation of 4-phenyl-2-butanone and sulfanilamide with some aromatic aldehydes at an yield of 23%-97%. The chemical structures of the twelve new Mannich bases were confirmed by 1H NMR, 13C NMR, FTIR, ESI-MS and HR-MS. The screening results of antidiabetic activity indicated that most of these title compounds possess alpha-glucosidase inhibitory activity, among which compound le is the strongest one. And compound 11 possesses good peroxisome proliferator-activated receptor response element (PPRE) agonist activity. The structure-activity relationship of these new beta-amino ketones containing benzenesulfonamide unit was also discussed preliminarily.

OBJECTIVETo test the feasibility of using 1,5-anhydroglucose alcohol (1,5-AG) as a diagnostic indicator of fulminant type 1 diabetes (FT1DM).

METHODSFifteen patients with newly diagnosed FT1DM and 52 with type 2 diabetes (T2DM) were examined for serum biochemistry, glycosylated hemoglobin (HbAlc), and serum 1, 5-AG level.

RESULTSThe patients with FT1DM and T2DM showed significantly different fasting levels of blood glucose (FBG), fructosamine (FMN), creatinine (Cr), urea, HbAlc and serum 1,5-AG (P<0.05). In FT1DM patients, serum 1,5-AG was found to inversely correlate with FBG (r=-0.646, P=0.032) and FMN (r=-0.680, P=0.021), and in T2DM patients, serum 1,5-AG was inversely correlated with FBG (r=-0.407, P=0.001), FMN (r=-0.314, P=0.01) and HbAlc (r=-0.576, P<0.01). Receiver-operating characteristic (ROC) curve analysis showed an area under the curve of serum 1,5-AG of 0.804 with a cutoff value of 67.95, a sensitivity of 82.9% and a specificity of 60% for FT1DM diagnosis.

CONCLUSIONSerum 1, 5-AG can reflect acute blood glucose fluctuation in FT1DM patients and is useful for differential diagnosis of FT1DM when combined with evaluations of the clinical characteristics of the patients and other related indicators.

Objective:To investigate the correlation between gallbladder polyps and colon polyps of different locations.Methods:Healthy subjects who underwent colonoscopy in the Physical Examination Center of the Affiliated Hospital of Yangzhou University from January 2020 to October 2022 were included. They were divided into the proximal colon group and the distal colon group according to the location of colon polyps. Gallbladder polyps were compared with other known risk factors for colon cancer. Different parts and types of polyps were further explored.Results:A total of 2 811 patients had colon polyps, including 1 668 males and 1 143 females, with an average age of 47.3 years. One hundred and seventy-one (6.1%) had gallstones, and 459 (16.3%) had gallbladder polyps. The incidence of gallbladder polyps was higher in the proximal colon polyp group (21.7%, 93/429). Gallbladder polyps were independently associated with proximal colon polyps, including hyperplastic polyps ( OR=1.525, P=0.029) and adenomatous polyps ( OR=1.425, P=0.017). There was no significant correlation between gallbladder polyps and distal colon polyps. Conclusion:Gallbladder polyps are associated with proximal colon polyps, and colonoscopy screening is recommended for people with gallbladder polyps.

Objective To evaluate the significance of AFP-IgM, this is one of new tumor markers, in the diagnosis of primary hepatocellular carcinoma (PHC). Methods The contents of AFP-IgM and AFP in serum of 103 healthy subjects, 74 patients suffered primary hepatic carcinoma, 27 patients affected by liver cirrhosis and 63 patients affected by chronic hepatitis were detected by means of enzyme linked immunosorbent assay and electrochemiluminescence. No-PHC is comprised of liver cirrhosis,chronic hepatitis and health subjects as control group. Results The area under ROC curve of AFP was larger than that of AFP-IgM (0.85 vs 0.72, Z=3.21) and the best cut-off value of AFP-IgM and AFP was 3×105-AU/L and 10 ug/L respectively, which was determined by ROC curve. Under the cut-off value, the sensitivity of AFP- lgM and AFP for PHC were 64.9% and 79.7%, and the specificity were 75.6% and 80.3%, yet their efficacies were similar. However, for early diagnosis of liver cancer (stage Ⅰ and Ⅱ), the area under ROC curve of AFP-IgM was larger than that of AFP (0.91 vs 0.82,Z=1.73). The sensitivity of AFP-IgM andAFP were 94.4% and 72. 2%, and the specificity were 81.9% and 79.9%. The differences of AFP-IgMand AFP for early diagnosis of liver cancer were statistically significant. When both of the test results combined AFP-IgM with AFP are positive, it can be diagnosed as liver cancer. The specificity of combineddetermination of the two forms was 89.1%, and the efficacy was 79. 0%. Conclusions Both of thesensitivity and specificity of the AFP-IgM test were higher than that of the AFP for early diagnosis of livercancer. We also found that combined determination of the two forms significantly increased the specificityand the positive predictive value for the diagnosis of PHC, thus AFP-IgM was of especially significance forearly diagnosis of liver cancer.
