Objective To investigate the clinical effects of the modified Kock method of bladder re- construction with ileum,and to provide the objective basis for wide application of this technique.Methods A total of 51 patients with bladder cancer(T_2N_0M_0 stage tumor in 37 cases,T_3N_0M_0 stage tumor in 14; and pathologic gradeⅡ-Ⅲin all)were included.After radical cystectomy,modified Kock reconstruction of bladder with ileum was performed in them.The procedure consisted of preparing the segment of the ileum for reconstruction of the reservoir,anastomosing the low part of the neobladder with the urethra and regaining the original urinary conduit.Results The mean operative time was 6.5h(range,5.5-8.5h);mean in- traoperative blood loss was 650ml(range,300-1200ml),with blood transfusion in 31 cases.Perioperative complications included stress ulcer in 6 cases and urinary leakage in 1.The other 44 cases had no severe complications.Four cases died of cancer metastasis at 6-18 months after operation.During a follow-up of 8 -32 months,the other 47 cases recovered well and have been alive till now.Two cases had ureteral urine reflux with no impairment of renal function.The daytime urinary continent rate was 100%;and nocturnal uri- nary incontinence occurred in 6 cases.Conclusions The modified Koek reconstruction of bladder with il- eum can improve the patients'quality of life with fewer complications,therefore is a better treatment choice for infiltrative bladder cancer after radical eystectomy.

OBJECTIVETo explore the effect of nuclear factor erythroid-2 related factor 2 (Nrf2) and thioredoxin reductase (TrxR) gene on proliferation of chronic myeloid leukemia (CML) line cells and its mechanism.

METHODSFour interfering sequences of Nrf2 and one negative control sequence were designed and synthesised based on the principle of target sequence of siRNA, then constructed lentivirus vectors, which were transfected into K562 cell lines. The transfection effect was observed by laser scanning confocal microscope (LSCM) and flow cytometer (FCM); The depressing effect of siRNA was analyzed by real-time PCR. The cell proliferation inhibiting rate was measured with CCK-8 assay, the apoptotic rate by Annexin V-PE/PI with FCM and the apoptotic morphology of cells by LSCM.

RESULTSThe transfection efficiency of lentivirus was 65%. One cell line K562-C3 which significantly inhibited Nrf2 mRNA was obtained by real-time PCR, Nrf2 relative quantitation (RQ) expressions were 1.003±0.093 and 0.344±0.032 in the control group and K562-C3 respectively; TrxR expression also decreased with RQ as 1.090±0.549 and 0.395±0.029 respectively. The cellular proliferation inhibition rates of K562-C3 were (4.74±0.39)%, (6.13±1.78)% and (25.36±3.77)%, respectively at 24, 48 and 72 h. The apoptotic rate induced by K562-C3 (29.9%) at 72 hours was obviously higher than in the control group (7.9%). The Annexin V-PE positive K562-C3 cells presented the following apoptotic characteristics, such as karyopyknosis, nuclear fragmentation and apoptotic bodies observed by LSCM.

CONCLUSIONNrf2 specific siRNA could repress its expression at the cellular level and down-regulate the expression of its downstream antioxidant enzyme, such as TrxR, which lead to increased apoptotic rate and decreased cell proliferation.

OBJECTIVETo study the toxicity changes of different proportions of Radix Adenophora, Radix Glehniae combined with Veratrum nigrum L., thus providing acute toxicity data and investigating whether decoction factors were correlated with toxicity.

METHODSThe uniform design method was used by two factors and seven levels to investigate the toxicity changes in different proportions of Radix Adenophora, Radix Glehniae combined with Veratrum nigrum L. The decoction factors were also investigated.

RESULTSThe compatibility toxicity was affected mainly by Veratrum nigrum L. and the toxicity increased along with increased doses of Veratrum nigrum L. The toxicity of co-decoction was higher than mixed decoction in the same dosage of Radix Glehniae and Veratrum nigrum L. The promotion of the dissolution of the toxic component of Veratrum nigrum L. in co-decoction may be the cause of the higher toxicity.

CONCLUSIONRadix Adenophora and Radix Glehniae combined with Veratrum nigrum L. resulted in higher toxicity, which indicated that the incompatibility between Radix Adenophora, Radix Glehniae, and Veratrum nigrum L. In clinic practice, a prescription contained these drugs should be avoided.

Schizophrenia is a severe psychiatric disorder with an unclear etiology and various clinical manifestations. The diagnosis and consequent treatment of schizophrenia mainly rely on clinical symptoms. Multiple risk sites associated with schizophrenia have been identified, yet objective indicators have not been found to facilitate clinical diagnosis and treatment of schizophrenia. The development of omics technology provides different perspectives on the etiology of schizophrenia and make the early identification, diagnosis and treatment of the disorder possible. This article summarizes the prevalence of schizophrenia, reviews the research results and shortcomings of transcriptomics and proteomics, as well as the latest achievements and prospects of multi-omics, aiming to reveal the use of omics in SZ, provide more comprehensive biological evidence to reveal the complex pathogenesis of schizophrenia and provide a theoretical basis for the early identification, accurate diagnosis, disease progression control, and prognosis improvement of schizophrenia.

We investigated the potential hepatoprotective effect of Radix Bupleuri (RB) by inducing acute liver injury (ALI) in an animal model using acetaminophen (APAP) after pretreatment with RB aqueous extract for three consecutive days. Compared to those of the APAP group, the biochemical and histological results of the RB pretreatment group showed lower serumaspartate transaminase (AST) and alanine transaminase (ALT) levels as well as less liver damage. Pharmacokinetic study of the toxicity related marker acetaminophen-cysteine (APC) revealed a lower exposure level in rats, suggesting that RB alleviated APAP-induced liver damage by preventing glutathione (GSH) depletion. The results of cocktail approach showed significant inhibition of CYP2E1 and CYP3A activity. Further investigation revealed the increasing of CYP2E1 and CYP3A protein was significantly inhibited in pretreatment group, while no obvious effect on gene expression was found. Therefore, this study clearly demonstrates that RB exhibited significant protective action against APAP-induced acute live injury via pretreatment, and which is partly through inhibiting the increase of activity and translation of cytochrome P450 enzymes, rather than gene transcription.
