OBJECTIVEWilms' Tumor Trial (WT-99) of Shanghai Children's Medical Center was designed and conducted by applying therapeutic regimens stratified by stage and histology in accordance with National Wilms' Tumor Study (NWTS) criteria of U.S.A. The main aim of WT-99 was to reduce treatment of low-stage, favorable-histology (FH) tumors without impairing survival and to improve prognosis of stage III and IV (FH) and unfavorable-histology (UFH) tremors with more intensive chemotherapy.
METHODSDiagnosis and treatment was decided by the multi-disciplinary team including oncologists, surgeons, pathologists, radiologists and diagnostic radiologists. Twenty consecutively diagnosed patients were recruited between October 1998 and October 2002. The regimen for patients at favorable-histology (FH) stage I and II and anaplastic stage I was vincristine (Vcr) and dactinomycin (Act-D) only, while for those at focal anaplastic stage II to IV and FH stage III and IV the regimen was Vcr, Act-D and adriamycin (Adr). Patients at diffuse anaplastic stage II to IV and clear cell stage I to IV received four-drug regimen including Vcr, etoposide (VP16), Adr and cytoxan (CTX). For those at rhabdoid stage I to IV the regimen was carboplatin, VP-16 and CTX. Un-resectable patients received 2 courses of Ifosfamide, Vcr and VP-16 as pre-surgery therapy. No radiation therapy was used for patients at stage I and FH stage II.
RESULTSTwenty patients, from 7 months to 12 years old, were enrolled. Pathologic analysis showed fourteen cases were at their FH, three at unfavorable-histology (UFH), two at clear cell and one at rhabdoid stage. Five patients were at stage I, five at stage II, six at stage III, three at stage IV and one at stage V. Eighteen reached complete response (90%), and two failed. One relapsed after 24 months of CCR and reached the second CR after intensive chemotherapy. No therapy-related death happened. Survival rate (SR) was 90% (18/20) and event-free survival (EFS) was 85% (17/20) at 11-45 months, average 27 months.
CONCLUSIONMulti-disciplinary team work model and protocol WT-99 are safe and effective for Wilms' tumor.

OBJECTIVETo investigate the effects of adenovirus-mediated PTEN and P27 on the invasion of PC-3 in vitro and angiogenesis, along with their synergy in the treatment of prostate cancer.
METHODSRecombinant adenovirus vectors of the human tumor suppressor genes PTEN and P27 were constructed. The replication-incompetent recombinant adenovirus was packaged and propagated in HEK293 cells. The viral titer was examined by plaque assay and the mRNA and protein expressions of PTEN and P27 in human prostate cancer cell line PC-3 infected with Ad-PTEN and Ad-P27 were determined by RT-PCR and Western blot respectively. The invasion of PC-3 cells in vitro was examined by Boyden chamber assay. MTT assay was used to testify the effect of supernatant from PC-3 infected with Ad-PTEN and Ad-P27 on the proliferation of endothelial cells ECV-304 and the CAM test was used to testify the effect of PTEN and P27 on angiogenesis. The difference between the combined therapy group and the single gene therapy group was also examined.
RESULTSThe viral titers of Ad-PTEN and Ad-P27 were 1.8 x 10(7) pfu/ml and 1.2 x 10(9) pfu/ml respectively. Adenovirus infection verified that the mRNA and protein expression of PTEN and P27 were steady in human PC-3 cells. The invasion in vitro of PC-3 cells was significantly inhibited by infection with Ad-PTEN or/and Ad-P27. CAM and MTT assays of ECV-304 confirmed that the supernatant from PC-3 cells infected with Ad-PTEN or/and Ad-P27 could inhibit the angiogenesis effectively. There was a significant difference between the combined therapy group and the single gene therapy group.
CONCLUSIONThe combined gene therapy of Ad-PTEN and Ad-P27 plays a synergistic role in inhibiting the invasiveness of PC-3 cells and angiogenesis.

Objective:To study the correlation between the occurrence of diabetes mellitus complicated with erectile dysfunction (DMED) and serum fibroblast growth factor-21 (FGF21) level, analyze the role of FGF21 in the occurrence of DMED, and explore its predictive and diagnostic value for DMED.Methods:61 male patients with type 2 diabetes in Tai′an Central Hospital from January 2017 to June 2018 were selected as subjects. They were divided into 2 groups: DMED group ( n=30) and type 2 diabetes mellitus group (DM group, n=31). And 32 healthy persons were selected as control group. The general data of all subjects were collected, physical examination, genital examination and blood sampling were carried out for biochemical analysis. The erectile function was measured by International Erectile Function Index-5 (IIEF-5) questionnaire, and serum FGF21 level was detected by automatic biochemical analyzer. The correlation between IIEF-5 score with FGF21 and other indicators were analyzed by Spearman correlation analysis. Multiple linear regression analysis was used to analyze the related risk factors affecting DMED. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of FGF21 level for DMED. Results:(1) The serum level of FGF21 in the DMED group, DM group, control group were (112.5±9.2)pg/ml, (103.9±6.2)pg/ml and (91.9±3.9)pg/ml respectively, with significant differences (all P<0.05). (2) Spearman correlation analysis showed that IIEF-5 score was negatively correlated with FGF21, age, smoking, drinking, systolic blood pressure, diastolic blood pressure, glycated hemoglobin A1c (HbA 1c), fasting plasma glucose (FPG), total cholesterol (TC), total glyceride (TG), low density lipoprotein cholesterol (LDL-C), fasting insulin (FINS), homeostasis model insulin resistance index (HOMA-IR), and positively correlated with high density lipoprotein cholesterol (HDL-C) and testosterone( all P<0.05). The serum FGF21 level was positively correlated with smoking, drinking, systolic blood pressure, diastolic blood pressure, HbA 1c, FPG, TC, TG, LDL-C, FINS, HOMA-IR, and negatively correlated with HDL-C and testosterone ( P<0.05). (3) Multiple linear regression analysis showed that FGF21, HbA 1c, HOMA-IR and IIEF-5 were independent risk factors for erectile function (all P<0.05). (4) According to ROC curve, when the optimal cutoff value of FGF21 level was 102.75 pg/ml, the predictive sensitivity and specificity for DMED were 0.867 and 0.714, respectively. Conclusions:Serum FGF21 level is closely related to the occurrence of diabetes mellitus and DMED, which is an independent risk factor of DMED.

Ketamine is a phencyclidine derivative acting primarily as a noncompetitive antagonist of N-methyl-D-aspartate (NMDA) excitatory glutamate receptors. As a common intravenous anaesthetic in clinic, it is also increasingly abused because of its hallucination and addiction effects. Based on the pharmacological and toxicologic characteristics of ketamine and the acknowledged addiction mechanism of other abused drugs, this article reviews the possible addiction mechanism of the ketamine in the aspects of its enhanced effects and reward systems, the anatomic structures, the related receptors and the individual differences.

Schizophrenia is one of the common mental diseases. Because the mechanism of the schizophrenia is significantly complicated, the cause is still unknown. N-methyl-D-aspartate receptor antagonist can simulate the positive and negative symptoms, as well as the cognitive disorder of schizophrenia. Thus it has been widely used to establish the animal models of schizophrenia. The relationship of the three blocking agents of ion channels (phencyclidine, MK-801, ketamine) and the establishment of schizophrenia animal models is reviewed in this article.
