Abstract On August 11, 2022, Tongxiang Center for Disease Control detected a case of brucellosis, and the case was not engaged in related work. Case finding and risk factor investigation were immediately conducted to trace the source of infection. It was revealed that the case sold aquatic products at a farmer's market and frequently picked up goods at a seafood warehouse adjacent to a lamb slaughtering site. There was a potential risk of infection due to indirect contact with slaughtered lambs or contaminants. Serological tests were conducted on 9 employees of the slaughtering site and 48 residents nearby, and the brucellosis cases diagnosed in hospitals in the same area were searched. A total of 11 brucellosis cases were identified, including 9 confirmed cases and 2 asymptomatic infections. There were 2 cases of slaughtering workers and 9 cases of non-occupational individuals from the surrounding area of the slaughtering site. Brucella melitensis biovar 3 were isolated from a slaughtering worker and a non-occupational individual. The slaughtered lambs primarily came from northern regions such as Inner Mongolia and Heilongjiang. It was concluded that it was a cluster caused by Brucella melitensis biovar 3 and spread through direct or indirect contact with imported infected lambs or contaminated environments from a lamb slaughtering site. It is suggested to strengthen the quarantine of imported sheep, legally shut down non-compliant lamb slaughtering sites, implement designated slaughtering and enhance occupational protection.

Objective To establish the technique of hyperinsulinemic euglycemic clamp and to study the reference value of insulin sensitivity index in healthy Chinese. Methods According to the feedback mathematical model developed by DeFronzo, the technique of hyperinsulinemic euglycemic clamp was used in 90 healthy Chi- nese [ male:female =71 = 19; age; (28. 3±6. 1) years; body mass index (20. 9±1.5) kg/m2 ] to study die glu-cose metabolized rate. Blood samples were obtained at timed intervals in the fasting state and during the clamp for the measurement of glucose, insulin and C peptide. Results During the clamp tests, the blood glucose levels were con-trolled within 10% of target value. The coefficient of variation of glucose levels was 3. 8% 0.1%. In the steady state, the insulin sensitivity index (glucose metabolized rate, M value ) was (7.78±2.30) mg· kg-1 min-1, which was distributed normally. The lowest quartile of M value was 6. 286 mg·kg -1 min-1'. The coefficient of variation of M value was 9.4%±2.8%. Conclusion The technique of hyperinsulinemic euglycemic clamp and the reference value of insulin sensitivity index in healthy Chinese are successfully established in our center.

This study was designed to observe the clinical value of low-density lipoprotein immune complexes (LDL-ICs) in patients with type 2 diabetes mellitus (T2DM). Fifty-four patients with type 2 diabetes + macroangiopathy (DM-MA group), 48 patients with type 2 diabetes (DM group), 45 patients with macroangiopathy ( MA group), and 30 normal controls ( NC group) were enrolled. LDL-ICs levels in the DM-MA group were significantly higher than those in the other three groups. The levels of LDL-ICs in the MA group were higher than those in the NC and DM groups. There was a significant difference in LDL-ICs between the DM and NC groups. LDL-ICs levels were positively related with body mass index (BMI), glycesylated hemoglobin Alc(HbAlc), blood pressure, total cholesterol, and triglyceride. There was no significant relationship between low-density lipsprotcin cholesterol and LDL-ICs. A significantly negative correlation was recorded between high-density lipoprotein cholesterol and LDL-ICs. Our study suggests that LDL-ICs, blood pressure, and HbAlc may be risk factors of macroangiopathy in type 2 diabetic patients.
