Objective To investigate the brain protection of adenosine preconditioning in infants with tetralngy of Fallot (TOF) undergoing open heart surgery. Methods 120 patients with TOF undergoing open heart surgery were randomly divided into two groups: adenosine group and control group. Total dosage of 1.5 mg/kg adenosine was intravenously dripped in the adenosine group before the cardiopulmonary bypass. Serum S-100β and neurone specific enolase (NSE) were measured before the cardipulminary bypass, 30 min and 12 hours after the aorta off clamping. Results At 30 min and 12 hour after opening the aorta, the S-100β[(0. 346±0. 162)μg/L vs. (0.717±0.260) μg/L and (0.541±0.272) μg/L vs. (1.140±0.567) μg/L,P <0.001 ]and NSE[(10.43±5.54) μg/L vs. (15.75±7.96)μg/Land (15.54±7. 98)μg/L vs. (23.67±8.00)μg/L,P<0.001]were both lower in adenosine group than that in control group. Conclusion Adenosine preconditioning can reduce the S-100β and NES in infants with TOF undergoing open heart surgery and has brain protection.

Small molecule covalent inhibitors, or called as irreversible inhibitors, are a type of inhibitors that exert their biological functions by irreversibly binding to target through covalent bonds. Compared with non-covalent inhibitors, covalent inhibitors have obvious advantages in bioactivity. Nevertheless, these agents may also exhibit larger toxicity once off-target effects arise. This "double-edged swords" property often leads drug researchers to avoid attaching them. In recent years, some problems such as drug resistance are difficult to be solved with reversible inhibitors leading researchers to pay more attention on the covalent inhibitors. In this review, we shall make a short summary to the recent research progress of covalent inhibitors and the interaction modes between covalent inhibitors and their target protein residues.

This study examined the effects of Bangdeyun on the expressions of nuclear factor-kappaB (NF-kappaB), interferon-gamma (IFN-gamma) and interleukin-10 (IL-10) in the endometrium of mice with embryo implantation dysfunction (EID) during the implantation time (namely on pregnancy day 5, 6, 7 and 8) and explored the local immune regulatory effects of Bangdeyun. The gestational mice were randomly divided into normal group, model group and Bangdeyun-treated group. EID models of mice were established by using indomethacin. The endometrial expression of NF-kappaB was detected by immunohistochemistry and Western blotting. IFN-gamma and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that in the normal group, NF-kappaB and IFN-gamma were weakly expressed and IL-10 was strongly expressed in the endometrium during the whole implantation period. In the model group, the expressions of NF-kappaB and IFN-gamma were increased on pregnancy day 5, 6 and 7, and IL-10 expression decreased during the whole implantation time when compared with those in the normal group (P<0.01 for all). In the Bangdeyun-treated group, little amount of NF-kappaB and IFN-gamma was expressed and IL-10 expression was strong, much the way they were expressed in the normal group (P>0.05). The expressions of NF-kappaB and IFN-gamma were much lower in the Bangdeyun-treated group than those in the model group on pregnancy day 5, 6 and 7 (P<0.01 for all), while the expression of IL-10 was much higher than in the model group during the whole implantation time (P<0.01). It was suggested Bangderun may favor a shift from Th1- to Th2-type immune response, therefore inhibiting the maternal immune rejection, inducing the immune tolerance and improving the fetal implantation.

Based on thermodynamic principle, the critical relative humidity of electrolytes is closely related to their solubility. The authors explored the relationship theoretically and calculated critical relative humidity of 21 electrolytes from their solubility in the light of Raoult's law and extended Wilson model. The results indicate that the critical relative humidity values calculated by Raoult's law can not accord with the reported ones and there is a systematic error in the high concentration range; while these calculated by extended Wilson model are comparable to the reported ones.
