Objective:To analyze the clinical characteristics of dissociative symptoms induced by esketamine hydrochloride nasal spray in patients with treatment-resistant depression (TRD).Methods:The medical records of patients in phase Ⅲ clinical trials for the treatment of TRD who received esketamine hydrochloride nasal spray in Beijing Anding Hospital, Capital Medical University from June 2018 to February 2021 were collected. The general situation of patients (age, gender, comorbid diseases, etc.), the medication of esketamine hydrochloride nasal spray, the combined use of antidepressants, the time from medication to the occurrence of dissociative symptoms each time, duration, severity, evaluation results of causal relationship with esketamine application, intervention and prognosis were recorded, and a retrospective descriptive statistical analysis was performed.Results:A total of 21 patients with TRD were enrolled in the study, including 17 (81.0%) with dissociative symptoms, 10 males and 7 females; the age ranged from 20 to 53 years, with a median age of 36 years. All patients were treated with esketamine hydrochloride by nasal spray. The first dose was 56 mg, and the other seven doses were 56 mg or 84 mg, twice a week, lasting for 4 weeks. The 17 patients were all given combination treatment with oral antidepressants. A total of 88 times of dissociative symptoms occurred in the 17 patients. The time from medication to the onset of dissociative symptoms ranged from 4 to 128 min, with a median time of 15 min. The duration of dissociative symptoms ranged from 12 to 326 minutes, with a median time of 70 minutes. The dissociative symptoms were mostly mild. The causal relationship analysis between the esketamine hydrochloride nasal spray and the dissociative symptoms showed that it was definitely related in 6 cases, probably in 1 case, and possibly in 10 cases. The dissociative symptoms in all patients were subsided without intervention.Conclusions:Esketamine hydrochloride nasal spray can cause dissociative symptoms in patients with TRD, most of which occur within 30 minutes after the treatment. The duration of symptoms in most patients is less than 120 minutes, most of which are mild and can subside on their own, and the prognosis is good.

Objective To investigate the effect of miR-30a on human osteosarcoma cell 143B in migration,invasion andcellviability.Methods 143BcellswereinfectedortransfectedwithrecombinantadenovirusmiR-30a(Ad-miR30a) and miR-30a inhibitor respectively .Wound healing assay was performed to detect the cell healing ability ( P<0.05 ) .Cell migration and invasion ability were determined by Transwell assay ( P<0.05 ) .The cell viability was analyzed by MTT assay ( P<0.01 ) .Real-time quantitative PCR was performed to analyze the expression of RUNX2 mRNA level and confirmed the adenovirus miR-30a expressed in 143B cells.The expression of RUNX2 was analyzed by Western blot .miR-30a target to RUNX2 was verified by luciferase reported gene assay .Results The ability of migration and invasion was suppressed in osteosarcoma cell 143B by overexpression miR-30a,and the cell viability also decreased .After the endogenous miR-30 a being inhibited , the cell motility and invasion enhanced and the cell viability was promoted .The RUNX2 protein decreased after overexpression miR-30 a as compared with controlgroup.TheluciferaseactivityofRUNX2decreasedbyaddingmiR-30a.Conclusions 143Bcellmigration, invasion and viability were suppressed by miR-30a,and this process is potentially achieved via suppressing RUNX 2 protein expression .

Five patients after prosthetic tricuspid valve, who received pacemaker implantation via coronary sinus during Oct, 2011 and Jul, 2014, were enrolled. Pacemakers were implanted via coronary vein in 5 patients without complications. The stimulation thresholds keep stable and symptoms (such as short breath and fatigue) were disappeared during the follow-up. For patients after tricuspid valve replacement, implantation of pacemaker via coronary sinus provides a safe and invasive approach and avoids opening the chest again.

Aim To study ethanol-induced changes in the development and neuronal number of visual cortex in C57BL /6 mice. Methods Female mice were fed with ethanol during pregnancy . The neuron density (ND) and cortical thickness (CT) in visual cortex of off spring mice were measured at either P0, P7 and P14 with hematoxylin and eosin (H.E) and Nissl staining. Results Embryonic death and malformationswere found in the ethanol-treated groups. Malformations, such as microcephaly,anencephaly and myeloschisis with spinabifida, etc were found in late-term embryos. The malformation rate was 12%. Compared with control group, the development of visual cortex in ethanol-treated groups was delayed, and its lamination was in disorder. The neuron polarity was disturbed. Neuron loss was found after ethanol exposure. At various ages, the neuron density in ethanol-treated groups was lower than that in control group(P

Objective To study ethanol-induced the neuroapoptosis of visual cortex in offspring mice. Methods Pregnant female mice were fed by intubating alcohol daily,beginning on E5(embryonic,E) and continuing through the pup's birth.The neuroapoptosis in P0,P7 and P14 visual cortex was visualized by Caspase-3 activity immunohistochemistry and Terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling(TUNEL) staining. Results Usually,the pup's birth days would delay one or two days after ethanol exposure.Moreover,ethanol induced reabsorption of fetus and malformations,such as microcephaly,anencephaly and myeloschisis with spinabifida and so on,were found in the study.Apoptosis index in ethanol treatment groups was obviously higher than that in control at either P0,P7 or P14(P
