Abstract A suspected case of cutaneous anthrax was reported by Gongliu County Disease Control and Prevention Center, Ili Kazak Autonomous Prefecture, Xinjiang Uygur Autonomous Region on August 19, 2021. Then, an epidemiological survey was performed by a joint investigation team consisting of professionals from Xinjiang Uygur Autonomous Region Center for Disease Control and Prevention, intermediate-level trainees from the Field Epidemiology Training Program of Chinese Center for Disease Control and Prevention, and professionals from Ili Kazak Autonomous Prefecture Center for Disease Control and Prevention. A total of 11 cutaneous anthrax cases were identified, including 8 suspected cases and 3 clinically diagnosed cases, and all cases were villagers in Y Village, X Township, Gongliu County, without severe case or deaths found. The onset of the first case occurred on July 27, and the onset of the last case occurred on August 16. The main clinical manifestations included ulcerative eschar on hands and exposed skin of the upper extremity. A Bacillus anthracis isolate was detected in meat samples from infected cattle. Epidemiological surveys showed that villagers did not report infected cattle to related sectors and privately slaughtered and ate meat from infected cattle without any effective protective measures, resulting in this outbreak. It is recommended to strengthen health education for people raising, selling and slaughtering livestock, and publicize zoonotic disease control knowledge, including anthrax, and establish an effective surveillance and response system for anthrax for immediate identification and treatment of epidemics.

Objective To investigate the relationship of circulating zinc-α2-glycoprotein (ZAG) as well as adiponectin with adiposity and insulin resistance in humans.Methods Serum ZAG and adiponectin levels were determined by ELISA in 285 subjects with normal glucose tolerance (NGT),impaired glucose tolerance (IGT),and newly diagnosed cases with type 2 diabetes mellitus(T2DM).The relationships between circulating ZAG and insulin resistance or metabolic parameters were also explored.Results Circulating ZAG and adiponectin levels were all lower in T2 DM and IGT subjects than those in control subjects [ZAG:(37.14 ± 13.25 and 48.84 ± 18.74 vs 59.36 ± 16.20) mg/L,P＜0.05 or P＜0.01 ; adiponectin:(27.79 ± 11.23 and 33.00 ± 9.42 vs 41.81 ± 13.68) μg/L,P＜0.01].Circulating ZAG was correlated positively with high density lipoprotein-cholesterol and adiponectin (all P＜0.01),and inversely with body mass index,waist-hip ratio,FAT％,diastolic blood pressure,triglyceride,fasting blood glucose,fasting insulin,HbA1C,and homeostasis model assessment for insulin resistance(HOMA-IR,P＜0.05 or P＜0.01).By multivariate analysis,ZAG levels were independently associated with body mass index,HOMA-IR,diastolic blood pressure,and adiponectin (P＜0.05 or P＜0.01).Conclusions ZAG levels,associated with fat,insulin sensitivity,and adiponectin expression,are likely to play an important role in insulin resistance and energy homeostasis in humans.

BACKGROUND:Human and rat ovarian granulosa cels in dominant folicles have the phenomenon of expressing stem cel characteristics. OBJECTIVE:To investigate the expression of stem cel-related factors in rat ovarian granulosa cels. METHODS: After the paraffin sections of rat ovarian tissue, immunohistochemical method was used to detect CD34, CD133, ABCG2/Bcrp1, Pou5f1/Oct-4 expressions. Granulosa cels culturedin vitro were harvested by folicular puncture method, and then the immunohistochemical method was used to detect the expression of FSHR receptor in order to identify the purity of granule cels. In the cultured granulosa cels, CD44 and C-Kit expressions were detected immunohistochemicaly, RT-PCR was used to detect ABCG2/Bcrp1, Pou5f1/Oct-4, Nanog gene expressions in ovarian tissue and granulosa cels. RESULTS AND CONCLUSION:Immunohistochemistry detection on paraffin sections showed that a part of ovarian granulosa cels expressed CD34, CD133, ABCG2/Bcrp1 and Pou5f1/Oct-4, and the expression of Pou5f1/Oct-4 protein gradualy increased in the development of ovarian folicles, significantly enhanced during the luteal phase, and then disappeared after the formation of corpus albicans, displaying a periodic expression characteristics. FSHR receptor positive identification rate of primary cels harvested by the foliclar puncture method was more than 95%. Granulosa cels culturedin vitrowere mainly long spindle-shaped or diamond, and some cels presented with aggregation growth and expressed CD44 and C-Kit. RT-PCR test results showed that there were no Nanog in the ovarian tissue and cultured granulosa cels, low expression of Pou5f1/Oct-4 in the ovarian tissue, strong expression of ABCG2/Bcrp1 in the ovarian tissue, weak expression of Pou5f1/Oct-4 in the cultured granulosa cels, and strong expression of ABCG2/Bcrp1 in the cultured granulosa cels. These findings suggest that a part of granulosa cels in the rat ovarian have the characteristics of stem cels.

The study was aimed to investigate the effect of artesunate (ART) on the apoptosis of HL-60 cells in vitro and the expression of Bcl-2 and ICAD in the process of apoptosis induced by ART. The inhibition of ART on HL-60 cells were evaluated by means of MTT assay; cell apoptosis was detected by light microscopy, agarose gel electro-phoresis, flow cytometry; Western blot was used to analyze the expression of Bcl-2 and ICAD in cells during apoptosis induced by ART. The results showed that ART could significantly inhibit the proliferation of HL-60 cells in time-and dose-dependent manner. After treating HL-60 cells with ART for 48 hours, the IC(50) values was 18.33 microg/ml and its inhibition effect contributed to the induced apoptosis. Bcl-2 and ICAD proteins both all expressed in HL-60 cells, the level of expression declined as concentration increased. It is concluded that artesunate may induce apoptosis of HL-60 cells in vitro, Bcl-2 and ICAD may be an important control factor in the signal transduction pathway of ART-induced apoptosis.
