Adenosine monophosphate-activated protein kinase(AMPK) is a highly conserved serine/ threonine protein kinase which plays an important role in regulating energy metabolism of the systemic cells. Under stress conditions, such as ischemia and hypoxia, AMPK can be activated.Then it plays a neuroprotective role in regulating mechanisms such as oxidative stress, autophagy, apoptosis and neuroinflammation and so on. Researches have found that chronic cerebral hypoperfusion may be a major cause of vascular cognitive impairment(VCI).AMPK can exert neuroprotective effects on VCI by regulating the aforementioned pathological processes.Therefore, this article reviews the molecular biological characteristics of AMPK and its role and mechanism in VCI, with the aim of promoting further research on AMPK and making it a new target for VCI treatment.

Objective To investigate the efficacy and the collective brain responses of acupuncture for post-stroke limb numbness.Methods A total of 24 patients with post-stroke limb numbness and 23 matched healthy participants were recruited.Both groups received coordinated acupuncture treatment to regulate their physical and mental state,three times a week for 4 weeks.Changes in limb numbness assessed by the visual analog scale(VAS)were observed before and after acupuncture.Functional magnetic resonance imaging(fMRI)scans were conducted on the participants during the scanning process with acupuncture intervention.Blood oxygen level-dependent(BOLD)data were collected in three states:resting state,acupuncture task state,and needle retention state.Data processing was performed using software such as fMRIPrep and brainIAK.Intersubject correlation(ISC)analysis was conducted to compare the ISC values of different brain regions between the two groups under different conditions.Results Acupuncture treatment significantly reduced the VAS scores of limb numbness.No significant changes in ISC values in both groups during resting state.Under acupuncture conditions,the patient group exhibited significantly increased ISC values in the left precentral gyrus,left paracentral lobule,left postcentral gyrus,left insula,left anterior cingulate gyrus,right middle frontal gyruss and right anterior cingulate gyrus.Under the needle retention condition,a slight negative activation was observed in the bilateral precentral gyrus of the control group.In the patient group,the ISC values of the left superior frontal gyrus,left precentral gyrus,left paracentral lobule,left precuneus,left postcentral gyrus,left insula,left anterior cingulate gyrus,left thalamus,right superior frontal gyrus,right middle frontal gyrus,right precentral gyrus,and right anterior cingulate gyrus showed a significant increase compared to the resting state.Conclusion Acupuncture can improve post-stroke limb numbness symptoms and induce a specific pattern of collective brain activation in patients.This activation involves the precentral gyrus,postcentral gyrus,thalamus,insula,frontal lobe and cingulate gyrus.Acupuncture may enhance the processing of sensory information by activating the somatosensory-motor network and the cortical-thalamic-cortical loop.It may also modulate the central executive network and the descending pain control pathway to promote the relief of pain symptoms.

Objective To evaluate the therapeutic effect of evodiamine(Evo)on atopic dermatitis(AD)in rat models by regulating the cyclic adenosine monophosphate(cAMP)/protein kinase A(PKA)/cAMP response ele-ment binding protein(CREB)signaling pathway.Methods A rat model of AD was established by administration of multiple doses of 2,4-dinitrochlorobenzene(DNCB).The animals were randomly divided into AD group,Evo-low-dose(Evo-L,5 mg/kg)group,Evo-high-dose(Evo-H,10 mg/kg)group,Evo-H+H-89(5 mg/kg)group and dexamethasone(0.1 mg/kg)group.Normal rats were used as the control group and then the degree of skin damage of rats in each group was scored.Abdominal blood was taken to detect the levels of interleukin-4(IL-4),cAMP,and tumor necrosis factor-α(TNF-α)in serum;Skin lesion tissue was collected to detect pathological change,counting of mast cells,PKA/CREB related protein expression and expression of IL-4 and TNF-α mRNA in the tissue.Results Compared with control group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions of AD group were reduced,the severity score of skin lesions,level of IL-4 and TNF-α,epidermal thickness,number of mast cells and mRNA expression of IL-4 and TNF-α in skin lesion tissues were all significantly increased(P＜0.05).Compared with AD group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions in Evo-L group,Evo-H group,and dexamethasone group were increased,the severity score of skin lesions,level of IL-4 and TNF-α,epidermal thickness,number of mast cells,and mRNA expression of IL-4 and TNF-α in skin lesion tissues all reduced(P＜0.05).Compared with the Evo-H group,the level of cAMP in serum,the expression of p-PKA/PKA,and p-CREB/CREB in skin lesions in Evo-H+H-89 group was reduced and the severity score of skin lesion,level of IL-4 and TNF-α,epidermal thickness,num-ber of mast cells,and mRNA expression of IL-4 and TNF-α in skin lesion tissues significantly increased(P＜0.05).Conclusions Evo inhibits inflammatory response and pathological damage through regulation of cAMP/PKA/CREB signaling pathway in AD rat models.

ObjectiveTo analyze the monitoring data of schistosomiasis from 2004 to 2021 in Suzhou New District， Jiangsu Province， and to provide evidence for improving schistosomiasis elimination strategies. MethodsFollowing the Opinions on Prevention and Control of Schistosomiasis， Parasitic Diseases and Endemic Diseases in Suzhou and the Technical Plan for Prevention and Control of Schistosomiasis， Parasitic Diseases and Endemic Diseases in Suzhou， the monitoring of schistosomiasis in the population and snail habitats from 2004 to 2021 was conducted. The Mann-Kendall method and Joinpoint regression method were employed to analyze the trend of epidemic indicators （such as seropositive rate， prevalence of snail frames， etc.）. Time series analysis （exponential smoothing model） was conducted to predict snail occurrence. ResultsFrom 2004 to 2021， a total of 73 680 people were serologically tested for schistosomiasis， with a positive rate of 0.084%. The seropositivity rate showed statistically significant differences between different years （χ²=70.73， P<0.05）， but there was no significant trend over time. In addition， 3 053 fecal tests were conducted and no positive result was found. The snail habitats covered an area of 70.11 hm² and showed a decreasing trend （Z=-1.97， P<0.05）. A total of 30 093 frames were surveyed， of which 19.038% contained snails. The difference in the prevalence of snail frames between different years was statistically significant （χ²=7 203.09， P<0.05）， with a decreasing trend in the prevalence of snail frames （Z=-2.05， P<0.05）. A total of 26 296 live snails were seized and density of live snails was 0.874 snails per frame， showing a decreasing trend in the density of live snails （Z=-2.35， P<0.05）. A total of 12 391 snails were dissected and no infected snail was found. The areas treated with molluscicides remained stable at 264.60 hm². An area of 27.77 hm² achieved the goal of snail eradication through environmental modification， with a decreasing trend （Z=-2.44， P<0.05）. It is estimated that the prevalence of snail frames and snail density will remain relatively stable from 2022 to 2026， but the snail habitat area will fluctuate significantly， showing an increasing trend. ConclusionNo indigenous cases of schistosomiasis and no infected snails are reported， indicating the successful consolidation of schistosomiasis prevention and control measures. However， the snail habitat area fluctuates greatly with an increasing trend， suggesting the need for long-term Oncomelania snail monitoring in local areas.

Atherosclerosis (AS) is one of the pathological bases of ischemic stroke. AS caused by elevated low-density lipoprotein cholesterol levels is the main causative factor. However, recent studies have found that the traditional blood lipid indicators can not fully reflect the risk of stroke in high-risk populations. Non-traditional blood lipid parameters are developed from traditional blood lipid parameters, including remnant cholesterol (RC), non-high density lipoprotein cholesterol and a variety of blood lipid ratios, which may play a role in the prevention and treatment of cerebrovascular diseases. Among them, RC is increasingly recognized as a biomarker driving the residual risk of AS. It has been confirmed that RC is closely associated with the risk of cerebrovascular disease in the primary and secondary prevention studies of stroke.
