BACKGROUND: Cerebrovascular disease often causes dysfunction of the brain nerve, and nerve cel apoptosis is the important factor of cerebral nerve dysfunction. The excessive expression of c-fos can block the transduction of intracelular signal so that producing some apoptosis-promoting factors, which involve in nerve cel apoptosis process after ischemia injury of brain. Bcl-2 is an inhibited factor. It might to be the key to treat ischemic cerebrovascular disease by inhibiting or reducing the apoptosis of nerve cels after ischemia injury. OBJECTIVE: To investigate the therapeutic effect and mechanism of the Total Flavone of Hawthorn Leaf on chronic cerebral ischemia rats. METHODS: A total of 72 healthy male Sprague-Dawley rats were randomly divided into sham surgery group, model group, Total Flavone of Hawthorn Leaf group and ginkgo leaf group. Permanent bilateral carotid artery ligation was used to prepare chronic cerebral ischemia model in the model group, Total Flavone of Hawthorn Leaf group and ginkgo leaf group. Total Flavone of Hawthorn Leaf group and ginkgo leaf group respectively received 140 mg/kg Total Flavone of Hawthorn Leaf and 12.3 mg/kg ginkgo leaf intragastricaly for 36 days from 36 days after model induction. Model group and sham surgery group received 3.5 mL/kg physiological saline intragastricaly. RESULTS AND CONCLUSION: Compared with the model group, the expression of c-fos protein significantly deceased in the Total Flavone of Hawthorn Leaf group (P < 0.01), Bcl-2 expression levels significantly increased (P < 0.01), and Ca2+ content decreased (P < 0.05). Moreover, no significant difference in above indexes was detected between Total Flavone of Hawthorn Leaf group and ginkgo leaf group (P> 0.05). These data indicated that the protective effect of Total Flavone of Hawthorn Leaf on chronic cerebral ischemia was associated with its inhibition of neuronal apoptosis. Its mechanism of anti-apoptosis might be associated with up-regulating expression of Bcl-2, down-regulating expression of c-fos and decreasing Ca2+ content in brain.

Objective To evaluate the effectiveness of different medicine treatment strategies on the social functions promotion on the patients with treatment-resistant depression (TRD). Methods 375 Patients with TRD were randomly grouped into 8 groups, and each group was received 8 weeks different treatment for paroxetine,venlafaxine, mirtazapine, paroxetine plus risperidone, paroxetine plus sodium valproate, paroxetine plus buspirone, paroxetine plus trazodone,or paroxetine plus thyroxine, respectively. The efficacy and social functions were evaluated with HAMD-17, SDSS and SF-36. Results There were significant difference in SDSS scores between 8th week and the baseline( P＜0.01 ) , and for social functions factor scores of SF-36 there was significant difference between 4th ,8th week and the baseline in each groups( P＜0.01 ). There were significant difference in social functions factor scores of SF-36 and subtracting scores between 4th and 8th week in all groups except group paroxetine and group venlafaxine(P ＜ 0.05 or P ＜ 0.01 ). There were significant difference in SDSS subtracting scores at 8th week among 8 groups( paroxetine plus risperidone group 7.05 ± 6.39, mirtazapine group 6.53 ± 4.75, paroxetine plusthyroxine group 5.14 ± 4.94, paroxetine group 5.13 ± 4.94 ,paroxetine plus trazodone group 5.00 ± 4.94, paroxetine plus sodium valproate group 4.60 ± 4.09, venlafaxine group 4.57 ± 4.18, paroxetine plus buspirone group 4.24 ± 4.95 ) ( Z = 2.076, P ＜ 0.05 ), between group paroxetine plus risperidone and group venlafaxine , group paroxetine plus sodium valproate, group paroxetine plus buspirone,as group mirtazapine and group paroxetine plus buspirone(P＜ 0.05 ), respectively. The influencing factors on improving social functions are the severity, improvement of depressive symptoms and latest onset time. Conclusions These 8 treatment strategies all can promote social functions on the patients with TRD. But the intensity and chronological order of improvement werent the same among 8 groups. The influencing factors on improving social functions are the severity, improvement of depressive symptoms and latest onset time.

Objective·To compare the clinical features between different subtype bipolar patients with first mania episode, and to contribute to early identification of bipolar disorder. Methods·This study was based on the database named as National Bipolar Mania Pathway Survey (BIPAS). From November 2012 to January 2013, bipolar patients from 26 mental health facilities in China were enrolled in current study. The clinical features were compared between mania patients of different subtypes, including hypomania (groupⅠ), mania without psychotic symptoms (groupⅡ), mania with psychotic symptoms (group Ⅲ) and mixed state (group Ⅳ). Results·There was significant difference in the percentage of clinical symptoms between different subtype bipolar patients with first mania episode, especially the mania and anxiety related symptoms. Group Ⅰ, Ⅲ , Ⅳ were further compared with groupⅡ, which was considered as the typical bipolar disorder. The results showed that the mania related symptoms was significantly higher in group Ⅱ, but anxiety related symptoms was significantly higher in group Ⅰ, Ⅲ, Ⅳ. Moreover, Logistic regression analysis revealed that more eloquent or humor and unusually restless could be in favor of the diagnosis of hypomania; younger and mania or hypomania as first episode might be in favor of the diagnosis of mania with psychotic symptoms; older, national minorities and unusually restless could be in favor of the diagnosis of mixed state. Conclusion·The clinical features between different subtype bipolar patients with first mania episode are various, and analysis of the clinical features can contribute to early identification of bipolar disorder.

Objective:To quantitatively evaluate the left ventricular circumferential and longitudinal strain after percutaneous coronary intervention(PCI)in elderly patients with acute myocardial infarction(AMI)using speckle-tracking imaging(STI)on echocardiography.Methods:A prospective case-control study was conducted on 47 elderly patients diagnosed with ST-elevation AMI and undergoing percutaneous coronary interference(PCI)in our hospital from August 2017 to June 2020 as PCI-study group.The 35 normal subjects matched for age and sex were as a normal-control group.The longitudinal peak systolic strain(LPSS)and circumferential peak systolic strain(CPSS)were measured using STI at one week and three months after PCI in the two groups.Results:The values of LPSS and CPSS were apical segment > middle segment > basal segment, which was the similar between LPSS and CPSS.Compared with normal-control group, AMI-PCI group showed that CPSS and LPSS in each segment were significantly reduced at 1 week and 3 months after operation.Compared with the control group, all the CPSS and LPSS values were significantly decreased in AMI group at one week after PCI(-12.3±2.7)% vs.(-22.5±1.7)%( t=19.62, P<0.01); (-12.9±3.2)% vs.(-23.1±2.6)%( t=15.43, P<0.01). Both LPSS and CPSS values were improved at a certain extent at three months after PCI compared with AMI group at one week after PCI.The complete CPSS and LPSS values were significantly increased in AMI group at three months after PCI compared with one week after PCI(-16.8±2.6)% vs.(-12.3±2.7)%, ( t=8.23, P<0.01); (-17.0±3.3)% vs.(-12.9±3.2)%( t=6.11, P<0.01). But, there were still significant differences compared with the NC group(-16.8±2.6)% vs.(-22.5±1.7)%( t=11.29, P<0.01); (-17.0±3.3)% vs.(-23.1±2.6)%( t=9.04, P<0.01). Conclusions:The longitudinal and circumferential strain of left ventricle were severely damaged in elderly patients with AMI.The speckle-tracking imaging technique can be used to quantitatively evaluate the left ventricular strain and its improved situation after PCI in elderly AMI patients.

OBJECTIVE: To provide a basis for genetic counseling and clinical precision therapy by exploring the genetic etiology of a child with recurrent hypoglycemia convulsion accompanied by language retardation. METHODS: Peripheral blood samples were obtained from the proband, his sister and his parents. Whole genomic DNA was extracted and analyzed by the whole exon gene sequencing and confirmed by Sanger sequencing. RESULTS: The proband and his sister were found to carry compound heterozygous variants c.731T>A (p.M244L) and c.928G>A (p.G244S) of the GYS2 gene, which had not been reported in the past, the c.731T>A (p.M244L) site was derived from the maternal heterozygous mutation, while c.928G>A (p.G244S) site from the father heterozygous mutation. CONCLUSION The compound heterozygous variants c.731T>A (p.M244L) and c.928G>A (p.G244S) of the GYS2 gene were the genetic cause of glycogen storage syndrome type 0 in children, providing basis for family genetic counseling. When the patient had Hypoglycemia often accompanied with convulsions, which was easy to be misdiagnosed as seizures, and the antiepileptic treatment was ineffective. After genetic diagnosis, the seizure can be controlled by improving diet to maintain blood glucose stability.
