ObjectiveTo investigate the diagnoses of somatic diseases of inpatients with psychosis and hospitalized more then 2 years.MethodsThe material of all 350 inpatients were investigated and analyzed.ResultsThe first three psychiatric diagnoses were schizophrenia (61.32%), Alzheimer's disease (15.26%), mood disorder (4.74%). The first three diagnoses of accompanying somatic diseases were heart disease (8.68%), diabetes mellitus (8.42%), and hypertension (4.47%).ConclusionWith the changes of social environment, the disease pedigree of inpatients with psychosis changes, senile patients become more and more, and the incidence of concurrent somatic diseases gradually increases.

Objective To observe the effectiveness and side-effect of two cases of relapsed and refractory T-cell lymphoma (TCL) treated with thalidomide and interferon.Methods Two cases of relapsed and refractory TCL was treated with thalidomide and interferon, the efficacy and side-effect were observed, and the relevant literature was reviewed.Results The patients achieved partially remission after being treated with thalidomide and interferon.Conclusion Thalidomide in combination with interferon can be used as a second line therapy for relapsed and refractory TCL.

To retrospectively analyze the safety and efficacy of low dose subcutaneous decitabine regimen in patients with acute myeloid leukemia (AML) and intermediate-or higer-risk myelodysplastic syndrome (MDS).Of 6 AML cases,2 achieved complete remission (CR),2 with partial remission(PR),1 with stable disease(SD),1 with progressive disease(PD).As to the 8 MDS patients,one achieved CR and 6 with hematologic improvement (HI),1 case SD.Low dose subcutaneous decitabine regimen could be an alternative choice of older AML or MDS patients.

Objective To improve the cognition of sever liver injury of treating Philadelphia positive acute lymphoblastic leukemia (Ph+ ALL) with salvage chemotherapy of dasatinib combined with high-dose methotrexate (HD-MTX) and L-asparaginase (L-Asp).Methods Severe drug-induced liver injury caused by dasatinib with HD-MTX and L-Asp in one patient with Ph+ ALL was reported.Results Severe drug-induced liver injury happened on the seventh day after treatment,TBIL 221.7 μmol/L,DBIL 156.1 μmol/L,IBIL 65.6 μmol/L,ALT 111 U/L,AST 131 U/L,ALP 354 U/L,GGT 256 U/L,TBA 199.2 μmol/L.Through proper treatment,the patient recovered quite good,and the patient achieved complete remission after this chemotherapy.Conclusion Salvage chemotherapy which contains dasatinib,MTX and L-Asp can be effectively used in Ph+ ALL,but they are all of the hepatotoxicity,so drug-induced Liver injury may happen while they are used together.

In this study, we investigated the effect of Cigu Xiaozhi formula on HSC-T6 activity in hypoxic microenvironment based on network pharmacology and computer-aided drug design, and predicted and verified its possible targets and related signaling pathways. The potential active components and targets of Cigu Xiaozhi formula were screened by searching Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Encyclopaedia of Traditional Chinese Medicine (ETCM) and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM) databases, and the liver fibrosis related targets retrieved from Gene Cards and Pharm GK database were integrated to obtain the potential targets of Cigu Xiaozhi formula in the treatment of liver fibrosis. GO enrichment analysis and KEGG signaling pathway enrichment analysis were performed on Omic Share platform, and Cytoscape software was used to construct the "potential active ingredient-key target-pathway" network. The active components and target proteins were subjected to molecular docking analysis by Auto Dock software. According to the results of molecular dynamics simulation and binding free energy calculation, the top 5 active components with degree were scored. The active components stigmasterol and β-sitosterol were subjected to molecular docking. CoCl₂ was used to induce HSC-T6 cells to construct hypoxia model in vitro. The cell viability was detected by CCK-8 assay, and the optimal time and concentration of hypoxia model of HSC-T6 cells was determined to be 100 µmol·L^-1 CoCl₂ for 24 h. Under hypoxia condition, HSC-T6 cells were activated, the wound healing rate was significantly increased, and the fluorescence signal of activation marker protein α-smooth muscle actin (α-SMA) was significantly enhanced. However, 6% drug-containing serum could inhibit the activation of HSC-T6 cells, and the wound healing rate was significantly decreased, and the fluorescence signal of α-SMA was significantly weakened. Further studies showed that the expressions of hypoxia-inducible factor-1α (HIF-1α), α-SMA and key proteins of Hedgehog (Hh) signaling pathway in HSC-T6 cells were up-regulated under hypoxia, while the expressions of HIF-1α, α-SMA, Patched-1 (Ptch-1) and glioma related oncogene homology-1 (Gli-1) were down-regulated in 6% drug-containing serum group, the YC-1 group and the cyclopamine group. These results indicated that HIF-1α and Hh signaling pathways were involved in the activation of HSC-T6 cells, and the traditional Chinese medicine Cigu Xiaozhi formula could inhibit the activation of HSC-T6 cells, and the mechanism may be related to the inhibition of HIF-1α expression and the blocking of Hh signaling pathway. In conclusion, Cigu Xiaozhi formula can inhibit the activation of HSC-T6 cells by directly acting on HIF-1α and Hh signaling pathway, and exert an anti-hepatic fibrosis effect. The animal experimental protocol has been reviewed and approved by Laboratory Animal Ethics Committee of Gansu University of Chinese Medicine, in compliance with the Institutional Animal Care Guidelines.

OBJECTIVETo compare the clinical outcomes of open surgical peritoneal dialysis catheter (PDC) insertion with guide wire and the outcomes of PDC insertion without guide wire.

METHODSData of the patients receiving open surgical Tenkchoff straight catheter insertion in our department from January 2005 to January 2011 were retrospectively analyzed. The 117 patients in whom PDC insertion was conducted with the guidance of guide wire were enrolled into group A, and the 121 cases receiving PDC insertion without guide wire were enrolled into group B. The incidences of post-operative complications (catheter obstruction, catheter displacement, bloody dialysate, and dialysate leakage), catheter survival, and patient survival rates were compared between the 2 groups.

RESULTSThe baseline characteristics (gender, age, body mass index, prothrombin time, activated partial thromboplastin time, platelet count, serum creatinine, follow-up time, primary diseases, and outcomes) of the 2 groups were comparable (all P>0.05). In post-operative complications, only the incidence of early bloody dialysate showed significant difference, being 16.2% in group A and 7.4% in group B (P=0.04). Catheter and patient survival rates were not significantly different between the two groups. Overweight patients showed a higher incidence of catheter obstruction compared with normal weight patients [16.0% (4/25) vs.3.3% (7/213), P=0.02], but no differences in post-operative complications were found among overweight patients between the 2 groups.

CONCLUSIONSOpen surgical Tenkchoff straight catheter insertion without guide wire does not lead to higher risk of post-operative complications and catheter removal. It may be an alternative option when guide wire is not available.
