Network analysis of psychotic symptoms in schizophrenia.

Background: Schizophrenia with a wide range of psychotic symptoms which indicate the severity of disorders, risk of relapse, frequency and duration of hospitalization, and decreases social and occupational function. In clinical practice, Positive and Negative Systems Scale always used for assessment the severity of psychotic symptoms of patients with schizophrenia. This network analysis explores the inter-relationship of psychotic symptoms of patients with based on Positive and Negative Systems Scale (PANSS).

Importance of GWAS Risk Loci and Clinical Data in Predicting Asthma Using Machine-learning Approaches.

Introduction: To understand the risk factors of asthma, we combined genome-wide association study (GWAS) risk loci and clinical data in predicting asthma using machine-learning approaches.

Methods: A case-control study with 123 asthmatics and 100 controls was conducted in the Zhuang population in Guangxi. GWAS risk loci were detected using polymerase chain reaction, and clinical data were collected.

Associations between the HLA-A/B/DRB1 polymorphisms and aplastic anemia: evidence from 17 case-control studies.

Objective: To estimate the associations between HLA-A/B/DRB1 polymorphisms and aplastic anemia (AA), we carried out the meta-analysis.

Methods: In this meta-analysis, all publications in English and Chinese were considered up to 30 September 2015. The electronic databases we searched were Pubmed, Science Direct, Embase, Web of Science, CNKI, Wanfang Data and VIP.

The incidence and risk factors for central lymph node metastasis in cN0 papillary thyroid microcarcinoma: a meta-analysis.

Although there have been many studies identifying clinical and pathologic factors that may predict central lymph node metastases (CLNM) in papillary thyroid microcarcinoma (PTMC) patients without clinically cervical lymph node metastasis (cN0), the results were inconsistent. And whether prophylactic central lymph node dissection (pCLND) should be performed in cN0 PTMC remains controversial. The EMBASE, PubMed, MEDLINE and the Cochrane Library were searched until Oct 2015 to identify relevant studies.

Validity of the International HIV Dementia Scale as assessed in a socioeconomically underdeveloped region of Southern China: assessing the influence of educational attainment.

In 2012, more than 80,000 cases of HIV infection were recorded in the Southern Chinese minority autonomous region of Guangxi Zhuang, where the occurrence of HIV-associated dementia remains high. The International HIV Dementia Scale is a relatively simple-to-administer screening scale for HIV-associated neurocognitive disorders. However, clinical experience in utilizing the scale with large Chinese samples is currently lacking, especially among individuals with limited formal schooling.

Trends in prevalence, awareness, treatment, and control of diabetes mellitus in mainland china from 1979 to 2012.

Diabetes mellitus (DM) is one of the primary causes of premature death and disability worldwide. We performed a systematic review and meta-analysis of the published literature regarding the trends in prevalence, awareness, treatment, and control of diabetes mellitus in mainland China. PUBMED, EMBASE, Chinese Biomedical Database, China National Infrastructure database, Chinese Wan Fang database, and Chongqing VIP database were searched.

The prevalence and incidence of Parkinson's disease in China: a systematic review and meta-analysis.

Parkinson's disease (PD) is a chronic neurodegenerative disorder affecting older individuals. There is inconsistent evidence about the prevalence and incidence of PD in China at present. The aim of the meta-analysis was to estimate the prevalence and incidence of PD and its relation to age, gender, and stage in China.

The significance of combining radiotherapy with chemotherapy for early stage extranodal natural killer/T-cell lymphoma, nasal type: a systematic review and meta-analysis.

Abstract Radiotherapy is regarded as a primary treatment for early stage extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTL). However, whether combined modality treatment (CMT) comprising radiotherapy and chemotherapy is necessary remains controversial. A systematic review and meta-analysis of studies was performed to evaluate the significance of combining radiotherapy with chemotherapy for early stage ENKTL.
