ABSTRACT
Objective:To investigate the expression and significance of microRNA-21 (miRNA-21) and microRNA-181b (miRNA-181b) in the peripheral blood of patients with schizophrenia.Methods:A total of 100 patients with schizophrenia who received treatment in Shaoxing 7 th People's Hospital from March 2020 to March 2022 were included in the study group. An additional 30 healthy controls who concurrently underwent physical examination were included in the control group. The expression of miRNA-21 and miRNA-181b in peripheral blood was compared between the two groups. The 100 patients with schizophrenia received standardized clinical treatment. Their mental symptoms were evaluated with the Positive and Negative Symptom Scale (PANSS). miRNA-21 and miRNA-181b expression and PANSS scores before and 1, 4, 8, and 12 weeks after treatment were collected and compared between the two groups. The receiver operating characteristic curve was plotted to analyze the value of miRNA-21 and miRNA-181b expression in the diagnosis of schizophrenia. Results:Serum miRNA-21 and miRNA-181b expression in the study group were (2.41 ± 1.12) and (15.62 ± 2.26), respectively, which were significantly higher than (0.73 ± 0.37) and (8.11 ± 0.98) in the control group ( t = 8.07,17.67, both P < 0.05). With the prolongation of treatment time, serum miRNA-21 and miRNA-181b expression and PANSS score in the study group gradually decreased (all P < 0.001). The area under the receiver operating characteristic curve plotted for evaluating the value of miRNA-21 and miRNA-181b expression in the diagnosis of schizophrenia was 0.616 and 0.683, respectively. The area under the receiver operating characteristic curve plotted for evaluating the value of miRNA-21 combined with miRNA-181b expression in the diagnosis of schizophrenia was 0.788, which was markedly higher than that for the detection of miRNA-21 or miRNA-181b expression alone. Conclusion:miRNA-21 and miRNA-181b are abnormally highly expressed in the peripheral blood of patients with schizophrenia. Both of them can be used as objective and effective indicators for early diagnosis of schizophrenia. Combined detection of miRNA-21 and miRNA-181b provides higher accuracy in the diagnosis of schizophrenia than the detection of miRNA-21 or miRNA-181b alone.
ABSTRACT
Objective:To investigate the efficacy of work-amusement activities combined with daytime rehabilitation technology for schizophrenia in remission.Methods:A total of 218 patients with schizophrenia in remission who received treatment in Shaoxing 7 th People's Hospital from September 2018 to April 2020 were prospectively included in this study. They were randomly divided into an observation group ( n = 109) and a control group ( n = 109). Both groups were treated with routine drugs. Based on this, the control group was treated with daytime rehabilitation technology, and the observation group was treated with daytime rehabilitation technology combined with work-amusement activities. After 12 weeks of treatment, curative effect, Positive and Negative Symptom Scale (PANSS) and Montreal Cognitive Assessment (MoCA) scores were compared between the two groups. Results:After 12 weeks of treatment, total response rate in the observation group was significantly higher than that in the control group (91.74% vs. 77.06%, χ2 = 8.92, P < 0.05). After treatment, PANSS score in the observation group was significantly decreased compared with that before treatment [(33.12 ± 4.19) points vs. (40.54 ± 5.32) points, t = 11.44, P < 0.05). After treatment, PANSS score in the control group was significantly decreased compared with that before treatment [(35.02 ± 4.33) points vs. (40.54 ± 5.32) points, t = 8.55, P < 0.05). After treatment, PANSS score in the observation group was significantly lower than that in the control group ( t = 3.29, P < 0.05). After treatment, MoCA score in the observation group was significantly increased compared with that before treatment [(27.14 ± 2.89) points vs. (23.39 ± 2.48) points, t = 10.28, P < 0.05]. After treatment, MoCA score in the control group was significantly increased compared with that before treatment [(26.02 ± 2.73) points vs. (23.41 ± 2.56) points, t = 7.28, P < 0.05]. After treatment, MoCA score in the observation group was significantly higher than that in the control group ( t = 2.94, P < 0.05). Conclusion:The efficacy of work-amusement activities combined with daytime rehabilitation technology is marked on schizophrenia in remission, which can markedly improve mental symptoms and cognitive function.
ABSTRACT
Objective:To correlate serum homocysteine (Hcy) level with psychiatric symptoms and social ability in patients with schizophrenia.Methods:A total of 143 patients with schizophrenia who received treatment in the Third Hospital of Quzhou from January 2018 to January 2020 were included in this study. They were randomly divided into abnormal Hcy group (Hcy ≥ 10) μmol/L, n = 46) and normal Hcy group (Hcy < 10 μmol/L, n = 97) according to different serum Hcy levels. Baseline data, the scores of the Brief Psychiatric Rating Scale (BPRS), the Positive and Negative Syndrome Scale (PANSS), and the Substance Dependence Severity Scale (SDSS) were compared between the two groups. The correlation between serum Hcy level and psychiatric symptoms and social ability was analyzed using the Pearson correlation analysis. Results:PANSS total score and BPRS total score were (77.86 ± 8.37) points and (94.47 ± 9.36) points, respectively in the abnormal Hcy group, and (74.37 ± 7.94) points and (90.35 ± 9.26) points, respectively in the normal Hcy group. There were significant differences in PANSS total score and BPRS total score between the two groups ( t = 2.41, 2.47, both P < 0.05). SDSS total score was significantly higher in the abnormal Hcy group than in the normal Hcy group [(11.75 ± 2.38) points vs. (10.53 ± 2.28) points, t = 2.88, P < 0.05]. Pearson correlation analysis showed that serum Hcy level was positively correlated with PANSS positive subscale score ( r = 0.73, P < 0.001), general mental symptom score ( r = 0.43, P = 0.032) and PANSS total score ( r = 0.53, P = 0.027), but it was not correlated with PANSS negative symptom score ( P > 0.05). Serum Hcy level was positively correlated with BPRS excitement subscale score ( r = 0.42, P = 0.037) and hostility subscale score ( r = 0.37, P = 0.047), but it was not correlated with anxiety, blunted affect, unusual thought content subscale scores and BPRS total score (all P > 0.05). Conclusion:Serum Hcy level is correlated with psychiatric symptoms and social ability in patients with schizophrenia. The higher the level of Hcy, the more severe the psychiatric symptoms, and the higher the degree of social disability.
ABSTRACT
ObjectiveTo explore the anhedonia level and its relationship with cognitive function in patients with first-episode psychosis， and to analyze the influencing factors of cognitive function. MethodsA total of 143 first-episode psychiatric patients who met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） in the Affiliated Brain Hospital of Guangzhou Medical University from December 2016 to March 2019 were selected. Positive and Negative Syndrome Scale （PANSS） was used to evaluate the patient’s psychiatric symptoms， in which N2 （emotional withdrawal） and N4 （passive/apathetic social withdrawal） were used to assess the anhedonia level， and patients whose （N2+N4） scores beyond 4 were classified into anhedonia group， and those with （N2+N4） scores less than or equal to 4 were classified into non-anhedonia group. Hamilton Depression Scale-24 item （HAMD-24） was used to measure the depressive symptoms， and the MATRICS Consensus Cognitive Battery （MCCB） was used to detect cognitive function. Then the clinical symptoms and cognitive function of two groups were compared， and the influencing factors of cognitive function were screened by multiple linear regression analysis. ResultsThe negative symptom score， general pathological symptom score and total score of PANSS in anhedonia group were significantly higher than those of non-anhedonia group， with statistical difference （P<0.05）. The score of working memory in adolescent subgroup， the scores of information processing speed， attention/alertness and vocabulary learning in adult subgroup of anhedonia group were lower than those of non-anhedonia group， with statistical difference （P<0.05）. Multiple linear regression analysis showed that the anhedonia score and the duration of untreated psychosis were the influencing factors of working memory in adolescent subgroup （P<0.05）. ConclusionPatients with high levels of anhedonia suffer more severe mental symptoms and cognitive impairment， moreover， anhedonia is one of the influencing factors of working memory in adolescents.
ABSTRACT
Objective: To explore the feature and influencing factors of anhedonia in schizophrenia. Methods: A total of 71 schizophrenia patients and 50 healthy controls were recruited during December 2018 and December 2019. Positive and Negative Syndrome Scale (PANSS) was used for assessing psychotic symptoms. Temporal Experience of Pleasure Scale (TEPS) and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were applied to the evaluation of anhedonia and cognitive function respectively for each subject. Results: The evaluation result of TEPS showed both anticipatory and consummatory pleasure scores were lowered in patients with schizophrenia than those in healthy people (P=0.000). Stepwise linear regression analysis showed that negative subscale score of PANSS (B=-0.895, P=0.002) and delayed memory score of RBANS (B=0.265, P=0.001) were associated with anhedonia in schizophrenia. Conclusion: Patients with schizophrenia exhibit anticipatory and consummatory anhedonia, both of which are influenced by negative symptoms and delayed memory in schizophrenia.

ABSTRACT
OBJECTIVES: In the treatment of schizophrenia, treatment compliance is an important prognostic factor. As insight has a significant impact on treatment compliance, an appropriate assessment of insight is essential in the treatment of schizophrenia. This study examined the reliability and validity of the Korean version of Birchwood Insight Scale (BIS). METHODS: Fifty seven adult patients diagnosed with schizophrenia according to DSM-5 were recruited from a university hospital. They were evaluated using the Positive and Negative Syndrome Scale (PANSS), The Scale to Assessment Unawareness of Mental Disorder (SUMD) and BIS. Explorative factor analysis was performed to examine the construct validity of the Korean version of BIS. Concurrent validity was evaluated by a comparison with the PANSS G12 item and SUMD. The test-retest correlation was evaluated to examine the test-retest reliability. Multiple regression analysis was performed to examine the variables affecting insight. RESULTS: Explorative factor analysis showed that the Korean version of BIS was composed of 2 factors, which are ‘Awareness of symptoms’ and ‘Awareness of illness and need for treatment.’ The Korean version of BIS was reliable in terms of the internal consistency. Concurrent validity with the PANSS G 12 item and SUMD was statistically significant. The test-retest reliability was also statistically significant. Multiple regression analysis showed that the PANSS negative factor affects the BIS score, indicating that negative symptoms of schizophrenia may impair insight of the illness. CONCLUSION: This study suggests that the Korean version of BIS is a valid and reliable tool for assessing the insight of patients with schizophrenia.

ABSTRACT
Objective To explore the correlation of circRNAs' expression level to the negative-and positive symptoms of patients with schizophrenia (SZ).Methods Gene chip screening was performed with the peripheral blood samples from each five of SZ patients and normal controls.Nine circRNAs showing differentiate expression were confirmed,and further verification was done by real-time fluorescence quantitative PCR in 102 SZ patients and 103 normal controls.All the SZ patients were assessed with Positive and Negative Symptom Scale (PANSS).Results It was revealed that the expression levels of circRNA_102101,circRNA_102315,circRNA_104597,circRNA_101835 and circRNA_101836 were significantly down-regulated (P＜0.01 or P＜0.05),and circRNA_103102 and circRNA_103704 were up-regulated in SZ group (P＜0.01).The ACT value of circRNA_102101 and circRNA_103102 was positively correlated to the positive symptoms (P＜0.01 or P＜0.05),and the ACT value of circRNA_103704 also showed positive correlation with positive symptoms and general psychopathological symptoms (P＜0.01 or P＜0.05).The ACT values of circRNA_102101,circRNA_103102,circRNA_102315,circRNA_103704 and circRNA_102802 were correlated with thinking disorder (P＜0.01 or P＜0.05),and the ACT values of circRNA_102101,circRNA_103102,circRNA_104597,circRNA_103704 and circRNA_102802 were correlated with the activation (P＜0.01 or P＜0.05).The ACT values of circRNA_102101,circRNA_103102,circRNA_103704 and circRNA_102802 were positively correlated with paranoid (P＜0.01 or P＜0.05),and of circRNA_102101,circRNA_103102,circRNA_103704 and circRNA_102802 were markedly correlated with assault (P＜0.01 or P＜0.05).Therefore,circRNA_103704 was chosen into regressive equation of positive symptoms (P＜0.01),and circRNA_103704 and circRNA_102315 were chosen into regressive equation of general pathological findings (P＜0.01 or P＜0.05).Conclusion The expression levels of circRNA_103704 and circRNA_103102 are obviously up-regulated in SZ patients than in normal controls,and markedly correlated with the negative and positive SZ symptoms,so might be the dominant regulatory factors in the pathological process of schizophrenia.
ABSTRACT
Epidemiology indicates that schizophrenia affects approximately 8‰ of the world's population. The atypical (second and third generation) antipsychotics generally endowed with D2/5-HTHT2 receptors antagonism properties are commonly used as first-line drugs for the treatment of schizophrenia presently. They have been proven effective in the treatment of positive and negative symptoms of schizophrenia, but they are largely ineffective in the treatment of cognitive deficit. Moreover, the atypical antipsychotics are usually associated with cardiovascular and metabolic side effects such as QT prolongation and weight gain. To develop more potent antipsychotics with fewer side effects, more targets have been identified such as D3, glutamate, H3 receptors and PDE10A in recent years. Herein, the research progress of antipsychotics is reviewed.
ABSTRACT
OBJECTIVES: Disturbance in self-experience has been considered to be a core feature of schizophrenia. Evidence from mirror face-recognition tasks supports the connection between self-face recognition and self-awareness which is a part of self-experience. The aim of this study was to investigate the self-other boundary recognition using morphed face pictures in patients with schizophrenia. METHODS: Twenty-one patients with schizophrenia and twenty-three healthy controls completed the self-face recognition task that consisted of various morphed pictures. Participant's own picture was morphed with each of three different, unknown, gender-matched facial identities in steps of 10% ; each pair producing 11 images with graded blending of facial features. Thirty-three images in total were randomly presented as stimuli in a run, which was repeated three times. Participants were instructed to choose whether the stimulus was self-face or not. RESULTS: Self-face proportion was significantly lower in the schizophrenia group at both recognition start point I and II (33.33% vs. 53.04%, p<0.001 ; 61.43% vs. 70.87%, p=0.01, respectively). Using the mean value of each recognition start point in the control group, we calculated the difference in self-face proportion for each individual with schizophrenia. There was a significant correlation between the degree of this difference and total Scale for the Assessment of Negative Symptoms (SANS) score at recognition start point I (r=0.507, p=0.019). CONCLUSION: The difference in self-other boundary recognition in this study may account for self-disturbance of schizophrenia. Its correlation with SANS total score may reflect the shared nature of persistent disturbance between the disturbance in self-experience and the negative symptom.

OBJECTIVES: The purpose of this study is to investigate the factors related to long-term hospitalization of schizophrenia. METHODS: The subjects were inpatients with schizophrenia who were constantly hospitalized for more than 12 months and their caregivers. They were compared with schizophrenia with no previous experience of sustained hospitalization for more than 12 months and their caregivers. Demographic and clinical data, Korea version of the Positive and Negative Symptom Scale, functional disability and family burden scale were analyzed. RESULTS: In this study long-term hospitalization of schizophrenia was influenced by the following measures. First, primary caregivers variables such as parents/non-parents and cohabitation with patients, second, negative symptom severity of passive/apathetic social withdrawal and lack of spontaneity and flow of conversation, and third, functional disability of go to hospital/take a dose regularly and using public transportation/facilities were associated with long-term hospitalization. And they were significant in logistic regression analysis. CONCLUSION: The above results suggest that long-term hospitalization of schizophrenic patients in Korea might be affected by caregiver's factor, negative symptoms, and functional disability.

ABSTRACT
Objective To compare with the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) between the left and the right prefrontal on refractory negative symptoms and serum brain-derived neurotrophic factor (BDNF). Methods 80 hospitalized schizophrenics with refractory negative symptoms were divided into study group (n=40) and control group (n=40) randomly. Both groups were received 4-week treatment of 10 Hz rTMS. The stimulus lo?cation of the study group was the left prefrontal, and the control group was the right prefrontal. The type and dose of anti?psychotics remained unchanged during the treatment. The evaluation of positive and negative symptom scale (PANSS) and the measurement of BDNF concentration before treatment and after 4 weeks treatment was analyzed. Results Com?pared with before treatment, the total score of PANSS after treatment significantly decreased (P<0.05) both in the study group [(71.2±13.8) vs. (63.3±11.4)] and the control group [(70.3±13.4) vs. (63.7±12.2)]. The score of negative symptoms in the study group decreased [(22.8±6.6) vs. (18.4±5.9), P<0.01]. The BDNF concentration increased in the study group ](6.78±2.16) vs. (8.74±2.76)] and the control group [(6.83±2.32) vs. (8.66±2.70)]. Conclusion 10Hz rTMS on the left pre?frontal combined with drugs are helpful to improve the refractory negative symptom of the patients with schizophrenia. Stimulation on both left and right prefrontal lobe could increase serum BDNF concentration.
ABSTRACT
OBJECTIVES: The purpose of this study was to analyze the relationship between subjective well-being and other clinical parameters such as sociodemographic and clinical variables, which include positive and negative symptoms, depressive symptoms, insight, and side effects. METHODS: Fifty-one outpatients diagnosed with schizophrenia were recruited in this study. Subjective well-being was assessed using a self-rating scale, the Subjective Well-being under Neuroleptics-Short form (SWN-K). Sociodemographic variables were also evaluated and other evaluations were conducted using the Positive and Negative Syndrome Scale (PANSS), Calgary Depression Scale for Schizophrenia (CDSS), Liverpool University Neuroleptic Side Effect Rating Scale (LUNSERS), Korean Version of the Revised Insight Scale for Psychosis (KISP), and Multidimensional Scale of Perceived Social Support (MSPSS). The relationship between subjective well-being and these clinical variables was assessed. RESULTS: Education years and social support scores were positively correlated with the total SWN-K scores, but severity of illness, severity of depression, severity of side effect, and the scores on insight were negatively correlated. The stepwise multiple regression analyses indicated that the total SWN-K score of the patients with schizophrenia was associated with negative symptoms and insight. CONCLUSION: Better insight and more severe negative symptoms in patients with schizophrenia may be associated with worse subjective well-being. Results indicate that careful evaluation of subjective well-being is essential for proper management of patients with schizophrenia.

Objective To evaluate the influence of family intervention mode in patients with schizophrenia characterized by negative symptoms.Methods A total of 120 cases of hospitalized patients with schizophrenia characterized by negative symptoms were randomly divided into the observation group and the control group with 60 cases in each group.The observation group received treatment through family intervention mode based upon routine care,while the control group used routine care.Influences were assessed with Nurses’ Observation Scale for Inpatient Evaluation (NOSIE) and the Scale for Assessment of Negative Symptoms (SANS) before treatment and at the end of 6th,12th week treatment.Results No significant difference of NOSIE score or SANS score were found upon admission between the observation group and the control group.At the end of the 6th week or the 12th week,total and all factors’ scores of the NOSIE and SANS of both groups were better compared with pretreatment,the observation group was significantly better than the control group.Conclusions Family intervention model could significantly relieve the negative symptoms of schizophrenia,improve the patients’ clinical efficacy and is an effective adjunctive therapy for schizophrenia.
ABSTRACT
OBJECTIVE: The aim of this study was to explore the factor structure of a novel, 10-item rating scale, the Targeted Inventory on Problems in Schizophrenia (TIP-Sz). Determining the factor structure will be useful in the brief evaluation of medication and non-medication treatment of the disease. METHODS: An exploratory factor analysis was performed on TIP-Sz scores obtained from 100 patients who met the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria for schizophrenia. RESULTS: The factor analysis extracted four factors that were deemed clinically pertinent, which we labeled: disorganization, social cooperativeness, functional capacity, and emotional state. The items exhibited cross-loadings on the first three factors (i.e., some items loaded on more than one factor). In particular, the 'behavioral dyscontrol and disorganization,' 'insight and reality testing,' and 'overall prognostic impression' items had comparable cross-loadings on all of the first three factors. The emotional state factor was distinct from the other factors in that the items loading on it did not cross-load on other factors. CONCLUSION: The TIP-Sz scale comprises factors that are associated with the psychosocial functioning and emotional state of patients, which are important outcome parameters for successful treatment of the disease.

OBJECTIVES: In patients with schizophrenia, the prevalence of smoking is significantly higher than that of the general population. This study aimed to evaluate the relationships between cigarette smoking and socio-demographic and clinical characteristics in patients with schizophrenia in South Korea. METHODS: Post analysis of 2008-2009 three multi-center studies on the paliperidone extended-release switching was performed. A total of 509 patients with a diagnosis of schizophrenia were recruited and interviewed regarding socio-demographic variables, smoking characteristics. Krawiecka Scale, Clinical Global Impression-Schizophrenia-Severity, Clinical Global Impression-Schizophrenia-Improvement, and Personal and Social Performance Scale were used to evaluate psychological disturbance. Safety assessments included adverse events, evaluation of extrapyramidal symptoms using the Drug Induced Extra Pyramidal Symptoms Scale, and laboratory tests. RESULTS: The results revealed that the prevalence of smoking in Korean patients with schizophrenia is significantly higher than that of the general population. Male, patients with occupation, and paranoid type showed higher rate of smoking and smokers with schizophrenia had higher rates of overweight, thick waist, high blood pressure than non-smokers with schizophrenia. The results revealed that smokers with schizophrenia had higher rating scales of negative and cognitive symptoms. CONCLUSION: From this study, we reported significant relationships between cigarette smoking and socio-demographic and clinical characteristics in patients with schizophrenia in South Korea. More studies will be needed to evaluate the association between cigarette consumption and schizophrenia, effect of smoking according to the antipsychotics, mechanism of nicotine on schizophrenia.
