Objective This study aimed to investigate the levels of non-enzymatic antioxidants among patients with depression at different age stages.Methods One hundred thirty five patients with depression(including 63 elderly patients aged 60 years and older,and 72 young and middle-aged patients under 60 years old)and 98 healthy controls(including 46 elderly controls aged 60 years and older,and 52 young and middle-aged controls aged under 60 years old)were enrolled.Serum levels of non-enzymatic antioxidants(uric acid,total bilirubin,albumin)were assessed.Results Multiple analysis of variance showed the main effects of depression factors on uric acid and total bilirubin were significant(P<0.05).Uric acid[(314.30±85.18)μmol/L vs.(339.68±85.27)μmol/L],total bilirubin[(12.81±6.16)μmol/L vs.(15.09±5.97)μmol/L]levels were lower in patients with depression than in controls(P<0.05).There was an interactive effect between age and depression factors on the levels of albumin(P<0.001),and the levels of albumin[(41.05±3.97)g/L vs.(46.01±4.49)g/L]were lower in group of the elderly patients with depression than those in group of the young and middle-aged patients with depression(P<0.01).Conclusion Patients with depression have abnormalities in levels of non-enzymatic antioxidants which are more severe in elderly patients.

Objective:To explore the association between cognitive function and the level of gamma-amino-butyric acid(GABA)in anterior cingulate cortex(ACC)before and after treatment in patients with major depres-sion disorder.Methods:Totally 31 medication-naive patients with major depression disorder meeting the criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)and 33 normal controls were col-lected.Each eligible patient received treatment with selective serotonin reuptake inhibitor agents for 8 weeks.The MATRICS Consensus Cognitive Battery(MCCB)was used to evaluate the cognitive function.By means of 1H magnetic resonance spectroscopy,anterior cingulate cortex GABA concentrations were measured.Results:At base-line,the concentration of ACC GABA relative to water(GABA+/W)was lower in the patient group than in the control group(P＜0.05)and increased after treatment(P＜0.05).ACC GABA+/W was negatively associated with verbal learning and visual memory score in patient group at baseline(correlation coefficient and P value were r=-0.40,P＜0.05;r=-0.42,P＜0.05,respectively).The ACC GABA+/W difference resulted of treatment in patient group was positively associated with the difference of working memory score and the difference of reasoning and problem-solving score(correlation coefficient and P value were r=0.58,P＜0.05;r=0.66,P＜0.05,respec-tively).Conclusion:The cognitive dysfunction of patients with major depression disorder may not be related to the degree of depression and anxiety.And improvement of cognitive function may be associated with increase of ACC GABA concentrations.

Ulcerative colitis （UC） is a chronic non-specific digestive disease with abdominal pain， diarrhea， and blood and mucus in stool as the main clinical manifestations and inflammatory injury of colorectal mucosa and submucosa as the main pathological changes. With the change in living habits and dietary structure of people， the incidence and cancer morbidity in UC are rising rapidly all over the world， which has seriously reduced the quality of life and caused a huge social burden. Till now， the pathogenesis has not been elucidated. In western medicine， aminosalicylates， corticosteroids， and immunosuppressors are commonly used to relieve symptoms. However， the long-term application will lead to problems such as decreased efficacy and increased adverse reactions. There are more studies of traditional Chinese medicine （TCM） in the treatment of UC by reducing the inflammatory response， alleviating oxidative stress， protecting the intestinal mucosal barrier， and regulating intestinal microecological imbalance by virtue of the advantages of integrated regulation based on multiple links， levels， and targets. In view of this， the present study reviewed the effect and mechanism of active ingredients of TCM， TCM extracts， TCM pairs， classic TCM compounds， and TCM combined with chemical agents in the treatment of UC based on relevant research articles in recent 10 years to provide references for seeking effective drugs.

The paper reports a case of coenzyme Q10 deficiency nephrotic syndrome associated with coenzyme Q2 gene mutation and reviews the literature on this topic. The patient presented with hematuria, proteinuria, and a diminution of vision as clinical manifestations. But the proteinuria was not relieved after sufficient doses of glucocorticoids for over 2 months. The patient′s birth history was unremarkable, and his parents were both healthy and not consanguineous. Whole exome sequencing revealed that the patient had a mutation of coenzyme Q2 gene at c.973A>G(p.T325A) and c.517C>T(p.R173C). Combined with renal biopsy pathology, the patient was diagnosed with hereditary nephropathy and started the supplements of coenzyme Q10 after stopping glucocorticoid treatments immediately. After 5 weeks of therapy, the patient′s 24-h urine protein quantification decreased from 6.01 g to 1.53 g.

Objective To explore the effect of Naikan cognitive-music reminiscence therapy on coping style in female patients with chronic schizophrenia.Methods In May, 2020, 72 female patients with chronic schizophrenia from Beijing Huilongguan Hospital were assigned into control group (n = 48) and music group (n = 24) after trait matching. Both groups accepted routine medicine, while the control group accepted Naikan cognitive therapy, and the music group accepted Naikan cognitive therapy combined music reminiscence, for twelve weeks. They were blind assessed with Simplified Coping Style Questionnaire, Self-rating Depression Scale and Self-rating Anxiety Scale before and after intervention.Results There were five cases in the control group removed for erroneous response. The main effects of group were not significant for all the assessments (F < 0.567, P > 0.05). The main effect of time was significant for negative coping style score (F = 6.968, P = 0.01), and the interaction effects were significant for positive coping style score and Self-rating Depression Scale score (F > 4.227, P < 0.05).Conclusion Combining with music reminiscence, Naikan cognitive therapy may be advantageous for the coping style of female patients with chronic schizophrenia.

Objective:To establish the quality evaluation method of Astmgali Radix based on three-dimensional fluorescence spectroscopy. Methods:The three-dimensional fluorescence spectra of Astmgali Radix extract was measured by fluorescence spectrum analysis technology, and the characteristics of fluorescence components of three-dimensional fluorescence spectrum of Astmgali Radix were analyzed by parallel factor analysis. The three-dimensional fluorescence spectra of Astmgali Radix samples from 23 different places were measured for quality discriminant analysis. Results:After the optimization, the three-dimensional fluorescence spectrum of 80% ethanol extract of Astmgali Radix showed that three groups of characteristic excitation/emission (λex/λem) peak, which located at 305 nm/420 nm (Peak 1), 280 nm/315 nm (Peak 2) and 265 nm/475 nm (Peak 3), respectively. The results of parallel factor analysis showed that Peak 1 and Peak 3 both contained one isoflavones fluorescent component, and Peak 2 contained two amino acid fluorescent components. There were differences in the number of characteristic peaks and fluorescence intensity of three-dimensional fluorescence spectra of Astmgali Radix samples from different origins. Conclusion:The three-dimensional fluorescence spectrum could evaluate the consistency of Astmgali Radix from different places. The method is simple, fast, and efficient. This method is accurate, which could provide reference for the quality evaluation of Astmgali Radix.

Objective:To investigate whether ginkgo biloba extract(EGb) can improve the symptoms of tardive dyskinesia(TD) by increasing the levels of serum brain-derived neurotrophic factor (BDNF), and to explore whether the BDNF Val66Met genotype can influence the efficacy of TD by EGb.Methods:A total of 78 male schizophrenia inpatients with TD were enrolled, and 77 patients completed 12 weeks of treatment with EGb(240 mg/d). The abnormal involuntary movement scale (AIMS), positive and negative syndrome scale (PANSS) and serum BDNF levels were measured at before and after 12 weeks of treatment.Serum BDNF levels were measured by enzyme linked immunosorbent assay (Elisa). In addition, the BDNF Val66Met polymorphism was genotyped by the method of PCR-restriction fragment length polymorphism (PCR-RFLP) in all patients.Results:Compared with before treatment, the scores of total AIMS((7.0±2.9) vs (4.9±2.2)), total PANSS ((55.8±14.0) vs(51.1±9.7)), subscale P((9.6±3.3) vs (8.6±2.2)), subscale N((23.2±8.3) vs (21.4±6.3)) and subscale G((23.0±4.9) vs (21.1±2.7)) were significantly decreased( P<0.01), while the levels of BDNF were significantly increased((10.8±2.9)μg/L vs (9.6±3.3)μg/L, P<0.05) in TD patients after treatment.The increased level of BDNF was positively correlated with the decrease of AIMS( r=0.28, P=0.014), but no significantly correlated with the improvement of PANSS total scores and the three subscales were found(all P>0.05). After treatment, the decrease of AIMS in patients with Val/Val genotype was significantly greater than that in patients with Val allele (Met/Val plus Met/Met genotype) (both P<0.05). Further analysis showed that only patients with Val/Met heterozygotes had a significant increase in BDNF levels after treatment ( P<0.05). Conclusions:EGb may improve TD symptoms through neuroprotective and regulatory effects.The BDNF genotype is involved in regulating the efficacy of EGb in the treatment of TD, which may be related to its regulation of BDNF serum levels.

Objective To investigate the level of serum vascular endothelial growth factor (VEGF) in stable schizophrenia patients, and to explore the relationship between serum VEGF level and clinical symptoms. Methods Seventy-five patients with stable schizophrenia and 40 healthy controls were enrolled. The levels of serum VEGF were detected by flow multiplex protein analysis. The clinical symptoms of patients were assessed by positive and negative symptom scale (PANSS). Results The level of serum VEGF was significantly lower in patients group than in healthy control group [medians (lower and upper quartiles) were 3.77 (2.61, 5.14) pg/mL vs. 6.21 (4.37, 11.16) pg/mL, P＜0.01]. There was no significant difference in serum VEGF levels between patients with different gender, smoking or family history of mental illness (P＞0.05). The level of VEGF was negatively correlated with the total score of PANSS (r=-0.27, P=0.03), negative symptom subscale score (r=-0.25, P=0.04), lack of response score (r=-0.26, P=0.02), but not with other PANSS scores (P＞0.05). Conclusion The serum level of VEGF in patients with stable schizophrenia is lower than that in healthy control group. There is, to some degree, a relationship between the level of VEGF and the severity of clinical symptoms in patients with stable schizophrenia.

Objective: To analyze the influence of cognition on suicidal ideation in patients with major depressive disorder. Methods: A total of 108 inpatients with major depressive disorder from January 2017 to September 2018 in Beijing Huilongguan Hospital were enrolled.They were divided into suicidal ideation group (n=42) and non-suicidal ideation group (n=66) by the self-rating idea of suicide scale (SIOSS). Cognition was assessed by Repeatable Battery for the Assessment of Neuropsychological Status(RBANS). The general situation was assessed by self-made general situation questionnaire.The related factors were analyzed by Logistic regression. Results: (1) The rate of suicidal ideation was 44.4% in patients with major depressive disorder.(2) The total score of RBANS and five-factor scores of RBANS in suicidal ideation group were lower than those in non-suicidal ideation group(total RBANS score(63.0±7.9) vs (73.8±7.7); immediate memory: (62.7±8.8) vs (70.8±7.6); visual span: (67.2±10.0) vs (72.7±9.8); speech function: (83.3±13.8) vs (91.5±4.5); attention: (85.3±11.9) vs (99.9±8.5); delayed memory: (53.5±7.7) vs (62.3±9.7), F=6.335-46.660, P<0.05). (3)Logistic regression showed, years of education were risk factors for suicidal ideation(β=0.289, P=0.013, OR=1.335, 95%CI=1.063-1.676), RBANS attention factor(β=-0.161, P=0.000, OR=0.851, 95%CI=0.778-0.931)and RBANS delayed memory factor score(β=-0.151, P=0.006, OR=0.860, 95%CI=0.772-0.957)were protective factors for suicidal ideation. Conclusion Cognitive function has an impact on suicide ideation of depressive patients, mainly attention and delayed memory are protective factors for suicide ideation.
