Aim To explore the effects of heat stress on TNF-?-induced fever and the content of cAMP in rat hypothalamus. Methods ①We examined the peak time of HSP70 expression in hypothalamus after heat stress; ②We studied the change of TNF-?-induced fever and the content of cAMP in hypothalamus after heat stress. Result The maximum expression of HSP70 in hypothalamus was attained at 12 h after heat stress. Heat stress limited TNF-?-induced fever and decreased the content of cAMP in hypothalamus. Conclusion Heat stress can inhibit TNF-?-induced fever in rats, and this effect may be related with the inhibition of cAMP synthesis induced by high expression HSP70 in hypothalamus.

To explore the influences of pregnancy and iodine intake on thyroid function and immune functions, 210 pregnant women and 290 fertile women were chosen from iodine excess area, and the average ages of them were (27. 69±4. 73 )and (30. 62±6. 01 )years respectively. Fasting blood and urine were collected in the morning. The urinary iodine level was determined by arsenic-cerium catalytic contact. Serum free triiodothyronine ( FT3 ), free thyroxine ( FT4 ), and sensitive thyroid-stimulating hormone ( sTSH ) levels were measured by chemiluminescence.Thyroid peroxidase antibody (TPOAb)and thyroglobulin antibody (TGAb)were measured by radioimmunoassay. The median urinary iodine in the pregnant and fertile women were I 240. 70 and 949. 21 μg/L, respectively. There were 84. 3% pregnant women and 81.0% fertile women admitting excess iodine intake. The prevalence of overall thyroid diseases was 22. 9% in the pregnant women and 30. 3% in the fertile women. The prevalence of hyperthyroidism,subclinical hyperthyroidism, hypothyroidism, and subclinical hypothyroidism was0. 5%, 1.9%, 0. 5%, and 20. 0% in the former group, and 2. 8%, 0. 3%, 0. 3%, and 26. 9% in the latter. Both FT3 and FT4 levels of the pregnant women were lower than those of fertile women [(4. 03±0. 59 vs 4. 71 ± 1.04)pmol/L, ( 13. 35 ± 1.59 vs 14. 27 ±3.63 )pmol/L,both P＜0. 01], and the positive rate of TGAb of pregnant women was also lower than that of fertile women (7. 1% vs14. 1%, P=0. 014). The prevalence of thyroid diseases and positive rate of thyroid autoantibodies is high in women with excess iodine intake. Compared with fertile women, pregnancy may lead to decreas~s in level of thyroid hormones and positive rate of TGAb. Their iodine intake should be controlled, and the thyroid function and autoimmunity antibodies should be monitored.

Chuangxinmycin (CM) from Actinoplanes tsinanensis was an antibiotic discovered by Chinese scientists about 40 years ago. It contains a new heterocyclic system of indole fused with dihydrothiopyran, whose biosynthetic mechanism remains unclear. CM is used as an oral medicine in the treatment of bacterial infections in China. The simple structure makes CM as an attractive candidate of structure modification for improvement of antibacterial activity. Recently, we analyzed the secondary metabolites of Actinoplanes tsinanensis CPCC 200056, a CM producing strain, as a natural CM analogue. We discovered the first natural CM analogue 3-demethylchuangxinmycin (DCM) as a new natural product. Compared to CM, DCM exhibited a much weaker activity in the inhibition of the bacterial strains tested. The finding provides valuable information for the structure-activity relationship in the biosynthesis of CM.

Objective To establish tree shrew model of type 2 diabetes mellitus (T2DM) combined with cerebral ischemia (IS),and to explore the regulatory mechanism of ischemic postconditioning (PC) on gene differential expression in cerebral cortex under metabolic abnormalities and cerebral ischemia condition.Methods Seventy tree shrews were divided into control,T2DM,IS,T2DM+IS and T2DM +IS +PC groups (n =14 each group).The experimental diabetes model was established by the combined use of high fat diet breeding with streptozocin injection in tree shrew.The local cerebral thrombosis was induced by photochemical reaction in tree shrews,and ischemic PC was established at 4h after cerebral ischemia followed by clipped ipsilateral common carotid artery three times (5 min/time).The metabolic status of tree shrews was measured by serum biochemical markers.TTC staining,HE staining,and electron microscopy were used to observe the changes of the body's metabolic status at 24h after IS.RNA-seq was used to analyze differentially expressed genes.Results The ultrastructure of brain cells was abnormal and the cerebral infarction area was the largest in T2DM+IS tree shrews (P＜0.01).Compared with control group,body weight of tree shrews in T2DM + IS group was significantly reduced (P＜ 0.01) while blood glucose,total cholesterol,low density lipoprotein-cholesterol,triglyceride,and C-reactive protein (CRP) levels were markedly increased(all P＜0.01).The RNA-seq analysis showed that there were 1 629 differentially expressed genes (1 109 up-regulated genes and 520 down-regulated genes) in T2DM + IS group vs control group.However,ischemic PC deceased the cortical infarction area (P＜0.01)and reduced blood glucose,lipid and CRP levels (P＜0.05),with 520 differential expression genes (203 up-regulated genes and 317 down-regulated genes).Conclusion Ischemic PC improves the metabolic disturbance-aggravated ischemic brain injury in T2DM tree shrews,which may be related to its regulation on gene expression in cerebral cortex.
