Methods Hospital charts of schizophrenic inpatients who discharged from six psychiatric hospitals in Tangshan in 1986,1996,2001, and 2006 were reviewed. Demographic and clinical character and prescription information at time of discharged of patients' was coded by trained investigators with a special designed form. Results The rates of combination antipsychotic therapy in the four years mentioned above were 13.2%, 18. 1% ,32.7%, and 28.9% ,respectively and the difference was statistically significant( x2 = 76.431, P ＜ 0.01; linear by linear x2 = 25. 542, P ＜ 0.01 ). Combined antipsychotic therapy in schizophrenic inpatients in Tangshan region show a increasing trend. There is significant difference of rate of combined antipsychotic therapy between hospitals. Combined antipsychotic therapy were associated with duration of illness,numbers of prior psychiatric hospital admission,hospital from which patients discharged,and discharged year.

Objective To explore the value of the electronic colposcopy Reid Score in diagnosis of cervical lesions and HPV infection in women with HIV infection, so as to find out an inexpensive, convenient and feasible screening methods. Methods 95 cases of HIV-infected women were screened by cervical liquid based cytology, HPV testing, colposcopy and Reid Score. The patients with abnormal results in any one test mentioned above underwent cervical biopsy. The colposcopy was combined with pathological as a gold standard for case-control study. Results There was a statistically signi?cant correlation between colposcopic ndings and histopathological ndings and the score was increased as parallel as malignancy grade (r=0.753,P=0.00) . The specificity of Reid score for high grade CIN was better than high-risk HPV testing for CIN diagnosis and the sensitivity was better than liquid based cytology. Acetic acid staining has relatively high sensitivity and specificity in the diagnosis of cervical lesions. Conclusions Colposcope Reid score for cervical lesions has a predictive value, especially for high grade cervical precancerous lesions. Colposcopy for HIV-positive women cervical cancer screening is an efficient and feasible way, especially for the area where lack of medical resources.

Long noncoding RNAs (lncRNAs) have recently been discovered and are increasingly recognized as vital components of modern molecular biology.Accumulating evidence shows that lncRNAs have emerged as important mediators in diverse biological processes such as cell differentiation,pluripotency,and tumorigenesis,while the function of lncRNAs in the field of normal and malignant hematopoiesis remains to be further elucidated.Here,we widely reviewed recent advances and summarize the characteristics and basic mechanisms of lncRNAs and keep abreast of developments of lncRNAs within the field of normal and malignant hematopoiesis.Based on gene regulatory networks at different levels of lncRNAs participation,lncRNAs have been shown to regulate gene expression from epigenetics,transcription and post transcription.The expression of lncRNAs is highly cell-specific and critical for the development and activation of hematopoiesis.Moreover,we also summarized the role of lncRNAs involved in hematological malignancies in recent years.LncRNAs have been found to play an emerging role in normal and malignant hematopoiesis,which may provide novel ideas for the diagnosis and therapeutic targets of hematological diseases in the foreseeable future.

OBJECTIVE: To investigate effects of antioxidant stress protein heme oxygenase-1 (HO-1) on lipopolysaccharide (LPS)-induced endoplasmic reticulum stress (ERS) of rat hepatocytes. METHODS: The BRL cells (rat hepatocyte cell line) were cultured. The hepatocytes were treated with LPS, LPS+HO-1 siRNA, HO-1 siRNA and PBS solution, respectively. The cell viability was measured by trypan blue exclusion test. The apoptosis cells were detected by the fluorescent dye Hoechst 33258. Expressions of GRP78, CHOP, caspase-12 and HO-1 were detected by Western blotting. RESULTS: LPS caused an increase of HO-1 protein expression of rat hepatocytes in a dose-dependent and time-dependent manner, a up-regulation of GRP78, CHOP and caspase-12, a decrease in cell viability, and an increase in apoptosis rate of hepatocytes. Pretreatment of HO-1 siRNA inhibited the up-regulation of LPS-induced HO-1, however, aggravated ERS and cellular injury. CONCLUSION HO-1 inhibites ERS-mediated cellular injury of rat hepatocytes induced by LPS.

Background Lupus nephritis (LN) is one of the most serious manifestations of systemic lupus erythematosus.Although there have been substantial improvements in LN treatment over the last decade,the outcome remains unoptimistic in a considerable percentage of patients.The aim of this study was to evaluate the efficacy and safety of mizoribine (MZR),a novel selective inhibitor of inosine monophosphate dehydrogenase,as induction treatment for active LN in comparison with mycophenolate mofetil (MMF) and intravenous cyclophosphamide (CYC).Methods Ninety patients with active LN were observed.Thirty patients were given MZR orally at the dose of 300 mg every other day.Thirty patients took MMF at 2 g per day in two divided doses.Thirty patients received CYC intravenously 0.5 g every 2 weeks.Therapeutic effects and adverse events (AEs) were evaluated at the end of 24-week treatment.Oneway analysis of variance (ANOVA) followed by Dunn's test was applied to compare the difference among the groups.For comparing categorical data between two groups,X2 test was employed.Results Early responses at week 12 were achieved by 73.3％,90.0％,and 96.7％ in MZR,MMF,and CYC groups,respectively.There was no significant difference in the complete remission rates (22.7％,24.0％,and 25.0％,respectively) or overall response rates (68.2％,72.0％,and 75.0％,respectively) among the three groups at week 24.The most prominent drop-down of Systemic Lupus Erythematosus Disease Activity Index scores was observed in MMF or CYC group,and the decline of health assessment questionnaire scores in MZR or MMF group was more prominent than that in the CYC group at week 12.Serum complement 3 (C3) or C4 levels were elevated in all groups after the treatments.CYC was more effective in inhibiting anti-double-stranded DNA antibody,while MZR was more effective in inhibiting antinuclear antibody.The incidences of AEs in patients treated with CYC were significantly higher than those in patients treated with MZR or MMF (24.2％ for CYC vs.3.3％ for MZR,and 2.6％ for MMF,P=0.01).Conclusions MZR is well tolerated and has an effect similar to MMF in the induction therapy of active LN.MZR may serve as an alternative approach for LN patients.
