Multidisciplinary team(MDT)diagnosis and treatment of colorectal cancer has been adopted by plenty of hospitals as a kind of effective comprehensive therapy.Compared with the traditional diagnosis and treatment methods,MDT diagnosis and treatment achieve standardization of diagnosis and treatment and technical promotion through specialization of the team to ensure better treatment and prognosis of patients.However,MDT diagnosis and treatment of colorectal cancer is not perfect,which can be limited by two aspects of hospitals and patients and can realize maximum utility with knowledge of its characteristics.This article will try to explore the distribution and usage of the resource in MDT diagnosis and treatment of colorectal cancer,the advantages over the traditional cure methods and the limits.

Objective To evaluate the efficacy and safety of ultrasonography-guided percutaneous nephrolithotomy(PCNL).Methods Between May 2006 and June 2008,110 patients underwent PCNL by a single urological team at our hospital.The clinical data of the patients were retrospectively reviewed.Of the cases,supracostal access(the 11th intercostal space) was made in 62 patients(supracostal group),and subcostal access was obtained in 48 patients(subcostal group).Forty-five patients in the supracostal group(45/62) and 36 of the subcostal group(36/48) received CT three dimensional reconstruction.Results The stone free rate of the supracostal group was 72.6%(45/62),while that of the subcostal group was 60.4%(29/48;?2=1.818,P=0.178).The mean operation time of the supracostal group was(78.6?5.1) min,while that of the subcostal group was(102.4?7.1) min(t=-20.454,P=0.000).There was one patient in each group received blood transfusion.One patient in the supracostal group had pneumothorax and recovered uneventfully by conservative treatments.Conclusion Ultrasonography-guided PCNL via the supracostal approach is effective and safe with short operation time.

Objective To determine the effects of lensspecific overexpression of OSM on the eye development. Methods A truncated mouse OSM cDNA (661 bp) was linked to the ?A-crystallin promoter. Transgenic mice were characterized by routine histological and immunohistochemical techiniques. TUNEL assays were used to detect cell death. The mRNA expression of caspase-3 was detected by in situ hybridization, Rabbit anti-cleavage caspase-3 antibody was used to detect active capase-3. Results At embryonic day (E) 14.5 and 17.5, expression of the OSM transgenic protein was detected specifically in lens fiber cells. The onset of retinal degeneration in the mid portion of the transgenic retinae was observed started from E17.5. By the time of birth 50% or more of the retinal cells were missing. The OSM transgenic retinal cells underwent apoptosis indicated by TUNEL assays. Most strikingly, activation of caspase-3 protein were observed throughout the transgenic retinas. Conclusions Lens-specific overexpression of OSM activate caspase-3, leading to abnormal eye development, apoptosis and widespread retinal degeneration.

Objective To summarize the efficacy of epirubicin chemotherapy by intra-iliac arteral infusion for the high risk patients of postoperative bladder cancer. Methods Eighty-six patients with the bladder cancer at high risk of recurrence who had undergone the bladder-sparing surgery were divided into two groups.Thirty-one patients were treated by intra-iliac arterial infusion chemotherapy of epirubicin and the remaining 55 patients had no chemotherapy.An analysis on recurrence related factors was made by multivariate Cox regression analysis models.And Kaplan-Meier curves were compared using the log-rank test on the disease-free between the two groups. Results Multi-recurrence associated with a higher grade and postoperative intra-iliac arterial infusion chemotherapy of epirubicin were significantly important factors,the former being risk factor and the latter being protective factor of cancer recurrence in bladder respectively.The recurrence of 9 in 31 patients (29%) with intra-iliac arterial infusion chemotherapy of epirubicin was significantly lower than that of 30 in 55 patients (54%) without chemotherapy ( P

Objective To determine the signal pathway of specifically expressed oncostatin M(OSM) in lens inducing retinal degeneration in transgenic mice. Methods A sequence-truncated OSM cDNA (661 bp) of mice was linked to ?A-crytallin promoter, and was micro-injected into unicellular embryo to set up the model of transgenic mice. Reversal transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA expression of gp130/OSMR? receptor in the retinae of OSM transgenic and non-transgenic mice. Rabbit anti-phosphorylated STAT-3 antibody was used to detect the protein expression of phosphorylated STAT-3,and mouse anti-cytochrome C antibody was used to detect the distributing of cytochrome C in retinae. Results Expression of gp130/OSMR? mRNA was found in retina of non-transgenic mice. At the 17.5th day in the embryonic stage, significant accumulation of the phosphorylated STAT-3 was detected in the retinal nucleolus in OSM transgenic retina. At the first day after birth, intensive staining of cytochrome C in OSM transgenic retina was found. Conclusions specifically expressed OSM in lens may act on gp130/OSMR? receptor in retinae, activate STAT-3, and cause the release of cytochrome C from mitochondria, which eventually induces widespread retinal degeneration.

Objective To study the distribution and tumor targeting property of anti-human prostate specific membrane antigen(PSMA) monoclonal antibody Ed-5 labeled with ~ 131 I in nude mice bearing human prostate cancer. Methods The nude mice xenografted models of human prostate cancer were established. Anti-human PSMA monoclonal antibody Ed-5 was labeled with ~ 131 I. ~ 131 I-Ed-5 was injected through the tail vein of nude mice bearing human prostate cancer. r-ray scintigraphy was performed at 24,48,96 and 144 hours after injection. And then the mouse were killed, the radioactivity ratio of tumor and non-tumor (T/NT), percentage of injected dosage of every gram tissue (%ID/g) were measured, and the bio-distribution of the labeled antibody was determined. Results The tumor imaging was clearly visualized at 96 hours after ~ 131 I-Ed-5 injection, and the tumor brim was clearer along with time prolonging. Radioactivity assembled in the tumors 24 to 144 hours after ~ 131 I-Ed-5 injection.
