OBJECTIVE:To compare Paliperidone sustained-release tablet and Paliperidone palmitate injection in the treatment of schizophrenia in respects of medium-term and long-term efficacy,safety,insight,medication compliance and social function of patients,so ad to provide reference for drug selection in the clinic.METHODS:Eighty-four schizophrenia patients selected from our center during Mar.2015-Jun.2016 were divided into Paliperidone sustained-release tablet group (group H,44 cases) and Paliperidone palmitate injection group (group Z,40 cases).Group H was given Paliperidone sustained-release tablet orally with initial dose of 3 mg/d,gradually increasing to 9 mg/d 2 weeks later according to disease condition;the drug dose was adjusted and ranged 3-12 mg/d according to disease condition.Group Z was given Paliperidone palmitate injection intramuscularly,150 mg on 1st day,100 mg on 8th day,and then given injection once a month,drug dose was adjusted according to disease condition (75,100,150 mg).Treatment course of 2 groups lasted for 12 months.Before treatment,1,2,3,6,9,12 months after treatment,Positive and Negative Syndrome Scale (PANSS) was used to evaluate therapeutic efficacy;Scale to Assess Unawareness of Mental Disorder (SAUMD) was used to evaluate the cognition of patients to disease;Medication Adherence Rating Scale (MARS) was used to evaluate medication compliance;Personal and Social Performance Scale (PSP) was used to evaluate patient's social function.The occurrence of ADR was observed during treatment.RESULTS:3,2 patients withdrew from group H,Z during treatment.Before treatment,there was no statistical significance in PANSS,SAUMD,MARS,PSP scores between 2 groups (P>0.05).1,2,3,6,9,12 months after treatment,PANSS and SAUMD scores of 2 groups were decreased significantly,while MARS and PSP scores were increased significantly,compared to before treatment,with statistical significance (P<0.05).9,12 months after treatment,PANSS and SAUMD scores of group Z were decreased significantly,while MARS and PSP scores were increased significantly,compared to group H,with statistical significance (P<0.05).There was no statistical significance in the occurrence of ADR between 2 groups (P>0.05).CONCLUSIONS:For schizophrenia,Paliperidone palmitate injection is better than Paliperi done sustained-release tablet in respects of medium-term and long-term efficacy,patient's insight,medication compliance,social function recovery;the longer the time,the more prominent the superiority.There is no significant difference in safety between them.

Objective The objective of this study was to investigate effects of miR-34a on the proliferation,invasion and migration of colon cancer SW480 cell and its possible mechanism.Methods miR-34a overexpressed lentivirus and empty virus vector were transfected into SW480 cells and untreated cells were used as blank control group.Real-time PCR was used to detect the expression of miR-34a in each group.The cell proliferation was detected by CCK8 assay.The cell migration and invasion ability were detected by wound healing and transwell assays.The expression of E-cadherin and Vimentin protein was detected by Western blotting.Results Compared with the empty virus vector group and the blank control group,the expression of miR-34a was increased in the transfected cells,and the cell proliferation efficiency,invasion and migration ability were decreased in the transfected cells (P < 0.05).miR-34a significantly increased the expression of E-cadherin protein and decreased Vimentin protein expression in the transfected cells.Conclusion miR-34a can inhibit the proliferation,invasion and migration of colon cancer SW480 cells,and affect the expression of E-cadherin and Vimentin.MR-34a is expected to be a potential molecular target for the metastasis and recurrence of colorectal cancer.

Because of the anomalous points distributed in the image, gene chip is hard to be distinguished effectively in fact. This article offers some arithmetic of image processing by VB such as increasing contrast, self-adapt thresholds, two-values and searching for spares and disperse templet which can distinguish all kinds of gene chip quickly, well and truly.

Objective:To compare the amino acid sequences difference of HA,NA novel influenza virus A/H7N9 isolates, decipher possible B cell epitopes and T cell epitopes of HA,NA protein,and analyze the association between susceptibility and HLA polymorphisms.Methods:The amino acid sequences of novel influenza A ( H7N9) virus were downloaded from Genbank.Phylogenetic trees were constructed based on the amino acid sequences of HA and NA by using software Clustal X and MEGA 4.0.B cell and T cell epitopes were respectively predicted with Protean software and NetMHCⅡ2.2 Server online server.Results:The homology of HA and NA proteins of H7N9 virus was high.10 B cell epitopes and 15 T cell epitopes were randomly distributed throughout HA sequence and 12 B cell epitopes and 9 T cell epitopes were randomly distributed throughout NA sequence.HLA-DRB1*0701 allele which was commonly observed in Northern Chinese population have a high binding affinity for 9-mer peptides of HA and NA proteins.Conclusion:The prediction of B and T cell epitopes of HA and NA proteins with multiple methods benefits the research and development of vaccine against human infection with avian influenza A H7N9 virus.HLA-DRB1*0701 allele may contribute to susceptibility to novel influenza A (H7N9) virus.H7N9 influenza virus is more easily spread in Urumqi,Harbin,Shandong Province,Liaoning Province,Beijing, Shijiazhuang and Tianjin of China.

Objective:To investigate the effect of somatostatin receptor ligands (SRLs) on bone metabolism in patients with acromegaly.Methods:Retrospective analysis of clinical data of acromegaly patients( n=100) received surgery or SRLs alone for 3 months. The changes of growth hormone (GH), insulin-like growth factor-1 (IGF-1), osteocalcin (OC), N-mid fragment of osteocalcin (N-MID), amino-terminal peptide of type I procollagen (P1NP) and C-terminal peptide degradation product of type I collagen(CTX) were compared before and after treatment. Patients were divided into drug treatment group and surgical group according to treatment methods. According to the decline of GH after medication, patients in the drug treatment group were further divided into drug sensitive group and drug insensitive group. Results:The average dynamic GH and IGF-1 indexes in the drug treatment group were significantly decreased after treatment compared with before treatment (both P<0.05), and CTX was also significantly decreased after treatment [1.25 (0.67, 1.40) ng/mL vs 1.34 (0.57, 1.68) ng/mL, P<0.05]. The mean dynamic GH, IGF-1 index, OC, N-MID, P1NP, and CTX in surgical group were significantly decreased after treatment compared with before treatment (all P<0.01). In the surgical group, there was a positive correlation between GH difference (ΔGH) and N-mid difference (ΔN-MID; r=0.454, P=0.026), and there was a positive correlation between IGF-1 index difference (ΔIGF-1 index) and CTX difference (ΔCTX; r=0.339, P=0.036). After treatment, the mean dynamic GH, IGF-1 index, CTX, P1NP, and N-MID in drug treatment group were significantly higher than those in surgical group (all P<0.001). CTX and N-MID decreased significantly after treatment in drug sensitive group compared with drug insensitive group (35.3% vs 7.2%, P<0.001; 24.1% vs 11.8%, P<0.05), and ΔGH was positively correlated with ΔCTX ( r=0.328, P=0.004). Conclusion:SRLs treatment can reduce bone formation marker N-MID and bone resorption marker CTX, improving the high turnover state of bone metabolism in patients with acromegaly, which may attribute to the reduction of GH and IGF-1 levels.
