Episodic memory, our ability to recall past experiences, is supported by structures in the medial temporal lobe (MTL) particularly the hippocampus, and its interactions with fronto-parietal brain regions. Understanding how these brain regions coordinate to encode, consolidate, and retrieve episodic memories remains a fundamental question in cognitive neuroscience. Non-invasive brain stimulation (NIBS) methods, especially transcranial magnetic stimulation (TMS), have advanced episodic memory research beyond traditional lesion studies and neuroimaging by enabling causal investigations through targeted magnetic stimulation to specific brain regions. This review begins by delineating the evolving understanding of episodic memory from both psychological and neurobiological perspectives and discusses the brain networks supporting episodic memory processes. Then, we review studies that employed TMS to modulate episodic memory, with the aim of identifying potential cortical regions that could be used as stimulation sites to modulate episodic memory networks. We conclude with the implications and prospects of using NIBS to understand episodic memory mechanisms.

BACKGROUND:Unilateral chronic ankle instability has adverse effects on the affected limb,and evidence has shown that the nonaffected side may be similarly involved,but direct evidence is currently lacking.OBJECTIVE:To investigate the effects of unilateral chronic ankle instability on bilateral postural stability,proprioception,plantar tactile sensation,and muscle strength.METHODS:A total of 122 participants were recruited in this study,including 67 individuals with unilateral chronic ankle instability and 55 individuals without chronic ankle instability.Postural stability,proprioception,plantar tactile sensation and muscle strength were tested bilaterally in individuals with unilateral chronic ankle instability,as well as in those without chronic ankle instability.One-way analysis of variance or Kruskal-Wallis test was used for intergroup comparisons.RESULTS AND CONCLUSION:(1)Compared with individuals without chronic ankle instability,individuals with chronic ankle instability had longer time to stability in the anterior-posterior direction bilaterally(P=0.001-0.012),and longer time to stability in the medial-lateral direction on the affected side(P=0.012-0.025);had higher proprioception thresholds of plantarflexion,dorsiflexion,inversion,and eversion of the bilateral ankles(P=0.000-0.035);showed lower tactile sensation sensitivities of the bilateral great toe,first metatarsal head,fifth metatarsal head,arch,and heel(P=0.000-0.008);and had weaker muscle strength for inversion and eversion of the bilateral ankles(P=0.000-0.019).(2)Individuals with unilateral chronic ankle instability have bilateral deficits in postural stability,proprioception,plantar tactile sensation,and muscle strength.Therefore,the rehabilitation needs of both limbs should be fully considered when treating chronic ankle instability.

Inflammation underlies a wide variety of physiological and pathological processes, and plays a pivotal role in controlling pathogen infection. C1q/tumor necrosis factor (TNF) related proteins (CTRPs), a newly discovered adipokine family with conservative structure and wide distribution, has attracted increasing attention. The CTRP family consists of more than 15 members which fall into the characteristic C1q domain. Increasing studies have demonstrated that CTRPs are involved in the onset and development of inflammation and metabolism as well as related diseases, including myocardial infarction, sepsis and tumors. Here, we first clarified the characteristic domains of CTRPs, and then elucidated their roles in inflammatory-related diseases. Taken together, the information presented here provides new perspectives for therapeutic strategies to improve inflammatory and metabolic abnormalities.

Objective:To design an oral methotrexate auxiliary device and explore the effect of methotrexate in patients with rheumatoid arthritis.Methods:Totally 30 patients with rheumatoid arthritis were selected and observed continuously for 12 months, from January to June in 2021, in the Affiliated Changzhou No. 2 People ′s Hospital of Naijing Medical University. The subjects took the medicine routinely in the first 6 months after entering the group, and the methotrexate oral drug assistant device was given in the latter 6 months to remind them to take the medicine correctly. Medication administration of patients before and after using the auxiliary device was compared, and the evaluation indexes such as disease activity, medication compliance and anxiety were observed. Results:Without the auxiliary device, there were 14 cases (46.67%) of medication error, 13 cases (43.33%) of medication time error, 9 cases (30.00%) of missed administration, while after the use of the auxiliary device, there were 4 cases (13.33%) of medication error, 2 cases (6.67%) of medication time error and 2 cases (6.67%) of missed administration, and the differences were statistically significant ( χ2=8.10, 9.09, 5.14, all P<0.05). Moreover, before using the auxiliary device, the scores of disease activity and medication compliance were 3.92 ± 0.95, 84.97 ± 6.49, respectively, while with the help of the auxiliary device, those scores changed to 3.29 ± 0.83, 92.40 ± 4.17 respectively. All the differences were statistically significant ( t=10.06, -10.37, both P<0.01). 16 cases (53.33%) were anxious after using the assistive device, which was also better than 26 cases (86.67%) before using the device. The difference was statistically significant ( χ2=8.10, P<0.01) . Conclusions:Oral administration aid for methotrexate can help rheumatoid arthritis patients to take methotrexate correctly and safely, reducing disease activity and anxiety, improving drug compliance. It is worthy to clinical promotion.

Objective:To evaluate the efficacy and safety of endoscopic ultrasound (EUS)-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices with large spontaneous shunt.Methods:Data of 24 patients with gastric fundal varices with large spontaneous shunt (the smallest diameter was 5-15 mm) treated by EUS-guided coil embolization combined with endoscopic cyanoacrylate injection in Renmin Hospital of Wuhan University from December 2016 to December 2020 were retrospectively analyzed. The short-term efficacy (the rates of technical success, five-day rebleeding and six-week mortality) and long-term efficacy (the rates of one-year rebleeding, one-year mortality and three-year mortality) and safety (ectopic embolism) were evaluated.Results:The technical success rate was 91.7% (22/24), and the five-day rebleeding rate was 0 (0/22). Computed tomography angiography of portal vein reexamined 2 days after the treatment showed embolism of splenic vein in 1 patient (4.5%). The median follow-up time was 14.9 months (ranging 1.0-48.6 months) and 2 patients were lost during follow-up. The six-week mortality was 0 (0/20), and the one-year rebleeding rate was 35.0% (7/20). Among 12 patients who underwent endoscopy in the follow-up, 5 had aggravation of esophageal varices, and 5 had aggravation of portal hypertension gastropathy. The one-year and three-year mortalities were 5.0% (1/20) and 20.0% (4/20), respectively, neither of which was related to such events as bleeding or ectopic embolism.Conclusion:EUS-guided coil embolization combined with endoscopic cyanoacrylate injection for gastric fundal varices with large spontaneous shunt is effective and safe in short term, with a low rate of ectopic embolism. Long-term efficacy and safety need to be further confirmed.
