The potential impacts of future climate changes on human health are having been widely paid more attention to.The direct and indirect potential impacts of future possible changes of climate on human health were reviewed in this paper.The methods for assessing the impacts of climate changes on human health were introduced also

Herpes simplex virus type 1 (HSV-1), as a pathogen usually leading to herpes labialis, has been found to cause more cases of genital herpes and be associated with the occurrence of neurological diseases such as Alzheimer′s disease (AD). AD is a chronic and progressive degenerative disease of the central nervous system, the pathogenesis of which has not been fully elucidated, and currently there is a lack of drugs that can effectively treat the disease. The hypothesis that HSV-1 infection is involved in the pathogenesis of AD has been discussed for a long time, but there is no definite evidence to prove it. This article briefly reviewed the research progress in the pathogenesis of AD caused by HSV-1.

Objective:To elucidate the possible role of galanin in the development of experimental depression in rats. Methods:Openfield was performed to test the behavior of rats. The changes of the galanin level in different brain areas were determined by RIA. The effect of fluoxetine hydrochloride on galanin level were observed by intraperitoneal injection. Results:Compared to control group, the crossing times and rearing times decreased significantly in depressed rats, galanin level decreased remarkably in plasma, hypothalamus, hippocampus, forebrain, parietal lobe and temporal cortex of depressed rats. Intraperitoneal injection of fluoxetine hydrochloride obviously improved the depressed behavior in rats, increased the galanin level in the hippocampus and forebrain of depressed rats. Conclusion:Hippocampus and forebrain may be involved in the development of experimental depression and in the antidepressive effects of fluoxetine hydrochloride.

Objective:To investigate the effect of goal-directed fluid therapy(GDFT)under the guidance of LIDCOrapid hemodynamic monitor on postoperative nausea and vomiting(PONV)of patients after gynecological laparoscopic surgery.Methods:A total of 90 patients who underwent laparoscopic extensive hysterectomy under general anesthesia in Affiliated Hospital of Shandong Second Medical University from August 2020 to June 2021 were selected,and they were divided into observation group and control group as random number table,with 45 cases in each group.Patients in control group supplemented fluid according to the guidance of urine output and mean arterial pressure(MAP).Patients in observation group supplemented fluid according to GDFT under guidance of stroke volume variation(SVV).The MAP values,heart rates(HR),SVV values and cardiac index(CI)values at the 10th min after patients entered the operation room(T0),the 3rd min after anesthesia induction(T1),and the 3rd min(T2),the 30th min(T3)and the 1st h(T4)after Terndelenburg position,and the time of completing surgery(T5)were observed.In addition,the intraoperative intake and output volume of liquid,the indicators of gastrointestinal function recovery after surgery,and the length of stay also were observed.The PONV incidence of main outcome indicators,and the PONV scores of postoperative 0-6h(T6),6-12 h(T7),12-24 h(T8)and 24-48 h(T9)of secondary outcome indicators,as well as the number of patients who received the treatment of antiemetic compensation after surgery,were analyzed.Results:The PONV incidence of observation group was significantly lower than that of control group(x2=6.40,P<0.05).The PONV scores of postoperative T6 and T7 of observation group were significantly lower than those of control group(t=4.92,3.42,P<0.05),respectively.The HR and CI value at T4 of observation group were significantly higher than those of control group(t=0.73,0.64,P<0.05),while the SVV of observation group increased from T3 to T5,with significant differences(t=2.28,3.42,4.10,P<0.05),respectively.The intraoperative crystalline fluid input and total infusion volume decreased,while colloidal fluid input increased,and the differences of them between two groups were significant(t=15.10,12.36,8.19,P<0.05),respectively.The postoperative exhaust time,defecation time and feeding time of observation group were significantly earlier than these of control group(t=3.79,2.09,2.54,P<0.05),respectively.But there was no statistical difference in the length of stay between the two groups.Conclusion:GDFT,which is guided by LIDCOrapid hemodynamic monitor,may decrease the incidence of PONV of gynecological laparoscopic surgery and the severity of PONV within 12 hours after surgery.
