Purpose To investigate the expression and clinical significance of RINGI and YYI binding protein (RYBP)in pancreatic carcinoma (PC).Methods RYBP expression was detected in 51 cases of PC tissues and paired adjacent nontumor tissues by immunohistochemistry.The correlation between RYBP expression and the survival time of PC patients after surgery was analyzed by Kaplan-Meier method.Results Compared to the expression in adjacent non-tumor tissues,RYBP was significantly lower expressed in PC tissues (P ＜ 0.05).In addition,RYBP expression had a significant correlation with tumor diameter and tumor staging of patients (P ＜ 0.05),but no significant correlation with other characteristics of patients,such as gender,age,smoking,alcohol intake,tumor number,metastasis or CA199 level (P ＞ 0.05).The survival analysis showed that the survival time of PC patients with positive expression of RYBP was significantly longer than patients with negative expression of RYBP (P ＜ 0.05).Conclusion RYBP is significantly lower expressed in PC tissues,which might be involved in the pathogenesis of PC.

OBJECTIVE:To investigate the utilization of antipsychotic drugs in hospitalized patients of our hospital to provide reference for rational use of drug. METHODS: The utilization of antipsychotic drugs in psychiatric inpatients in our hospital in Jul. 21th of 2008 was surveyed and analyzed. RESULTS: 734 patients were treated with antipsychotic drugs, involving 30 drug therapy schemes. 676 patients were only treated with one kind of drug (87.8%),among which the top 3 drugs in the list of utilization rate were risperidone (n=190, 24.7%), quetiapine (n=144, 18.7%) and olanzapine (n=123, 16.0%). Antipsychotic drugs were mostly combined with following drugs for mental disorder, such as antidepressant, mood stabilizers, benzodiazepine, sedative-hypnotic drugs, hypoglycemics and lipid regulators. CONCLUSION:The new atypical antipsychotic drugs have replaced traditional antipsychotic drugs and took up dominant position in the clinical treatment with single category.

This study examined the synergetic effect of class IA Phosphoinositide 3-kinases catalytic subunit p110β knockdown in conjunction with oxaliplatin treatment on colon cancer cells. Down-regulation of p110β by siRNA interference and oxaliplatin treatment were applied in colon cancer cell lines HT29, SW620 and HCT116. MTT assay was used to measure the inhibitory effect of p110β knockdown on the proliferation of colon cancer cell lines. SubG1 assay and Annexin-V FITC/PI double-labeling cytometry were applied to detect cell apoptosis. And cell cycle was evaluated by using PI staining and flow cytometry. The expression of caspase 3, cleaved PARP, p-Akt, T-Akt and p110β was determined by western blotting. The results suggested that down-regulation of p110β expression by siRNA obviously reduced cell number via accumulation in G(0)-G(1) phase of the cell cycle in the absence of notablely increased apoptosis in colon cancer cell lines HT29 and SW620 (S phase arrest in HCT116). Moreover, inhibition of p110β expression increased oxaliplatin-induced cell apoptosis and cell cycle arrest in HT29, HCT116 and SW620 cell lines. In addition, increases of cleaved caspase-3 and cleaved PARP induced by oxaliplatin treatment were determined by immunoblotting in p110β knockdown group compared with normal control group and wild-type group. It is concluded that down-regulated expression of p110β could inhibit colon cancer cells proliferation and result in increased chemosensitivity of colorectal cancer cells to oxaliplatin through augmentation of oxaliplatin-induced cell apoptosis and cell cycle arrest.

Objective This review aimed at assessing the diagnostic efficacy of contrast-enhanced single-photon emission computed tomography (SPECT) in the diagnosis of mandibular invasion by oral cancers. Methods Five databases were searched electronically on August 5, 2016. The reference lists of included studies were hand searched. Quality assessment was performed by two reviewers in duplicate with tools suggested by Cochrane's handbook. Furthermore, the data extraction of included studies was delivered. Meta-analysis was performed using STATA 11.0. Results Ten studies with 460 participants were included. One study had a low risk of bias, and two studies had a high risk of bias. The remaining seven studies had an unclear risk of bias. Meta-analysis results showed that SPECT had a pooled sensitivity of 0.99 [95% confidence interval=0.87-
1.00]. Sensitivity was 0.99 on Q* point. The specificity of 0.61 and the area under summary receiver operating characteristic curve (SROC) were 0.93 [95% confidence interval=0.90-
0.95]. The pooled positive likelihood ratio was 2.555. The negative likelihood ratio was 0.015. The diagnostic odd ratio was 5.115. Conclusion SPECT had high sensitivity, which became suitable for excluding bone invasion by oral cancers. However, its specificity was relatively low, indicating its limited capability in confirming diagnosis. Therefore, surgeons should perform this method under certain conditions.
