Cerebral small vessel disease(CSVD) is a common etiology of vascular cognitive impairment with no dementia(V-CIND). Studies have revealed that cerebral microbleeds(CMBs), a feature of CSVD, contribute to cognitive impairment. However, the association between CMBs and dementia conversion in individuals with V-CIND is still unclear. Here, we analyzed the predictive role of CMBs in the conversion from V-CIND to dementia in CSVD patients. We recruited and prospectively assessed 85 patients with CSVD and V-CIND. V-CIND was evaluated using a series of comprehensive neuropsychological scales, including the Chinese version of the Montreal Cognitive Assessment and the Clinical Dementia Rating. MRI assessments were used to quantify lacunar infarcts, white matter hyperintensities, CMBs, and medial temporal lobe atrophy. Eighty-two of the 85 patients completed the assessment for dementia conversion at a 1-year follow-up assessment. Multivariate logistic regression analyses were conducted to examine independent clinical and MRI variables associated with dementia conversion. Twenty-four patients(29.3%) had converted to dementia at the 1-year follow-up, and these individuals had significantly more CMBs in the fronto-subcortical circuits. Multivariate logistic regression analyses revealed that the patients with CMBs in the fronto-subcortical circuits(odds ratio = 4.4; 95% confidence interval: 1.602-12.081, P = 0.004) and 5 or more CMBs overall(odds ratio = 17.6, 95% confidence interval: 3.23-95.84, P = 0.001) had a significantly increased risk of dementia at the 1-year follow-up. These findings indicate that CMBs in the fronto-subcortical circuits may be predictive of dementia conversion in CSVD patients with V-CIND, and thus extend the clinical significance of CMBs. 展开更多

Background Hyperprolactinaemia is a common antipsychotic(AP)-induced adverse effect,particularly in female patients.Aims This meta-analysis examined the efficacy and safety of adjunctive aripiprazole in preventing AP-related hyperprolactinaemia in patients with first-episode schizophrenia.Methods PubMed,PsycINFO,EMBASE,Cochrane Library,WanFang and China Journal Net databases were searched to identify eligible randomised controlled trials(RCTs).Primary outcomes were the reductions of serum prolactin level and prolactin-related symptoms.Data were independently extracted by two reviewers and analysed using RevMan(V.5.3).Weighted/standardised mean differences(WMDs/SMDs)±95%Cis were reported.Results In the five RCTs(n=400),the adjunctive aripiprazole(n=197)and the control groups(n=203)with a mean of 11.2 weeks of treatment duration were compared.The aripiprazole group had a significantly lower endpoint serum prolactin level in all patients(five RCTs,n=385;WMD:-50.43 ng/mL(95%Cl:-75.05 to-25.81),p<0.00001;l2=99%),female patients(two RCTs,n=186;WMD:-22.58 ng/mL(95%Cl:-25.67 to-19.49),p<0.00001;l2=0%)and male patients(two RCTs,n=127;WMD:-68.80 ng/mL(95%Cl:-100.11 to-37.49),p<0.0001).In the sensitivity analysis for the endpoint serum prolactin level in all patients,the findings remained significant(p<0.00001;l2=96%).The aripiprazole group was s叩erior to the control group in improving negative symptoms as assessed by the Positive and Negative Syndrome Scale(three RCTs,n=213;SMD:-0.51(95%Cl:-0.79 to-0.24),p=0.0002;l2=0%).Adverse effects and discontinuation rates were similar between the two groups.Conclusions Adjunctive aripiprazole appears to be associated with reduced AP-induced hyperprolactinaemia and improved prolactin-related symptoms in first-episode schizophrenia.Further studies with large sample sizes are needed to confirm these findings. 展开更多

Background Hyperprolactinaemia is a common adverse effect of antipsychotics (APs). The results of Peony-Glycyrrhiza decoction (PGD) as a potentially useful adjunctivetreatment for hyperprolactinaemia are inconsistent.Aim This meta-analysis of randomised controlled trials (RCTs) examined the effcacy and safety of adjunctive PGDtherapy for AP-induced hyperprolactinaemia.Methods English (PubMed, Embase, Cochrane Library, PsycINFO) and Chinese (Chinese National Knowledge Infrastructure, Wanfang Data) databases were systematicallysearched up to 10 June 2018. The inclusion criteria were based on PICOS-Participants: adult patients with schizophrenia; Intervention: PGD plus APs; Comparison: APs plus placebo or AP monotherapy; Outcomes: effcacy and safety; Study design: RCTs. The weighted mean difference (WMD) and risk ratio (RR) along with their 95% CIs were calculated using Review Manager (RevMan) V.5.3 software.Results Five RCTs (n=450) were included and analysed. Two RCTs (n=140) were double-blind and four RCTs (n=409) reported ‘random’ assignment with specifc description. The PGD group showed a signifcantly lower serum prolactin level at endpoint than the control group (n=380, WMD: ?32.69 ng/mL (95% CI -41.66 to 23.72), p〈0.00001, I2=97%). Similarly, the superiority of PGD over the control groups was also found in the improvement of hyperprolactinaemia-related symptoms. No difference was found in the improvement of psychiatric symptoms assessed by the Positive and Negative Syndrome Scale (n=403, WMD: -0.62 (95% CI -2.38 to 1.15), p=0.49, I^2=0%). There were similar rates of all-cause discontinuation (n=330, RR 0.93 (95% CI 0.63 to 1.37), p=0.71, I^2=0%) and adverse drug reactions between the two groups. According to the Grading of Recommendations Assessment, Development and Evaluation approach, the level of evidence of primary and secondary outcomes ranged from ‘very low’ (14.3%), ‘low’ (42.8%), ‘modera 展开更多

Background: Optimizing treatment outcomes for depression requires understanding of how evidence-based treatments are utilized in clinical practice. Antipsychotic medications concurrent with antidepressant treatment are frequently used in major depression, but few studies have investigated trends and patterns of their use over time. This study aimed to examine the prescription patterns ofantipsychotic medications for major depression in China from 2002 to 2012 and their association with treatment satisfaction and quality of life (QOL). Methods: A total of 3655 subjects with major depression treated in 45 Chinese psychiatric hospitals/centers nationwide were interviewed between 2002 and 2012. Patients' socio-demographic and clinical characteristics including psychopathology, medication side effects. satisfaction with treatment and QOL were recorded using a standardized protocol and data collection. Results: The frequency ofantipsychotic use was 24.9% in the whole sample; the corresponding figures were 17.1%, 20.3%, and 32.8% in 2002, 2006, and 2012, respectively (χ^2 = 90.3, df= 2, P 〈 0.001 ). Multiple logistic regression analyses revealed that patients on concurrent antipsychotics had significantly more delusions or hallucinations, longer illness duration, greater side effects, and more likely to be treated as inpatients and in major hospitals (i.e., Level-Ⅲ hospital). Antipsychotic use was associated with lower treatment satisfaction while there was no significant difference with respect to physical and mental QOL between the antipsychotic and nonantipsychotic groups. Conclusions: Concurrent antipsychotic use was found in about one in four treated depressed patients in China, which has increased over a 10-year period. Considering the association of drug-induced side effects and the lack of patients' and relatives' satisfaction with antipsychotic treatment, further examination of the rationale and appropriateness of the use of antipsychotics in depression is needed. 展开更多

Owing to limitations on scalability, personal quantum computers still seem slightly unrealistic in the near future. The first practical quantum computer for ordinary users is likely to be on the cloud. However, the adoption of cloud computing is possible only if security is ensured. Homomorphic encryption is a cryptographic protocol that allows computation to be performed on encrypted data without decrypting them, so it is well suited to cloud computing. Here, we first applied homomorphic encryption on IBM's cloud quantum computer platform. In our experiments, we successfully implemented a quantum algorithm for linear equations while protecting our privacy. This demonstration opens a feasible path to the next stage of development of cloud quantum information technology. 展开更多
