ObjectiveTo compare the clinical characteristic and postoperative histopathological parameters in different prostate size and to assess the effect of prostate volume on histopathological outcomes in patients after laparoscopic radical prostatectomy. MethodsTwo hundred and sixteen patients from 2006 to 2011 who were proved prostatic carcinoma by biopsy and performed laparoscopic radical prostatectomy wewe retrospectively evaluated.All patients were divided into the small group ( < 30 ml,103 cases),intermediate group(30 -60 ml,71 cases) and large group ( >60 ml,42 cases) according to prostate volume.Clinical variables included age,body mass index (BMI),preoperative PSA level,prostate volume,percentage of positive needles,clinical stage,and biopsy Gleason score (GS).Histopathological parameters included pathological GS,upgrading or not compared to biopsy GS,pathological stage and surgical margins status.Preoperative clinical variables and postoperative histopatholgogical parameters were compared among the 3 prostate groups. ResultsPatients with smaller prostates had lower PSA levels than those with intermediate and larger prostates (P =0.000).They also had worse histopathological outcomes such as pathological GS ( P =0.034 ),upgrading of GS ( P =0.037 ),and pathological stage ( P =0.025 ).35.0% of patients in smaller prostate group had a positive surgical margin compare to 33.8% and 19.0% in intermediate and larger prostate groups,but there was no significant difference (P =0.152).ConclusionMen with smaller prostate may have more high-grade cancer and more advanced disease after laparoscopic radical prostatectomy.

To perform an evaluation of the on-going prospective clinical trials on particle radiation therapy and their impact on the current clinical practice as well as future clinical research and development.Furthermore,to briefly present the results of the registration trial of the IONTRIS particle therapy system at the Shanghai Proton and Heavy Ion Center.We used data from the clinicaltrials,gov and the Particle Therapy Collaborative Organization Group (PTCOG) website.After excluding retrospective and in silico studies,we examined and analyzed the prospective clinical trials for their ion type,targeting disease site,and nature.At the time of this analysis,149 prospective trials were identified on proton and carbon-ion radiation therapy,including 20 were carbon-ion and 129 trials were proton radiation focused,respectively.Except for 15 randomized phase Ⅱ/Ⅲ and Ⅲ trials,134 trials were phase 0-Ⅱ trials.Tumors from nearly all body parts were covered by the on-going trials,but trials on pediatric,GI,lung,prostate,and breast cancer account for the majority.The majority of the currently on-going trials focus on the efficacy and adverse-effects of the new dose/fractionation schemes of particle therapy as well as the use of particle therapy on new indications.Few studies invcstigate the addition of adjuvant therapy or imaging technology used in adjunct with particle therapy.Randomized trials that compare particle radiation therapy versus photon radiation is relatively uncommon.Despite the prevailing use of proton and heavy-ion radiation therapy for cancer treatment,~ 150 prospective clinical trials associated with particle radiation therapy are identified.As the majority of trials aim to investigate more efficacious dose/fractionation and the application of particle therapy on new indications,improved outcome from and expanded utilization of particle radiation therapy can be expected.

OBJECTIVE To understand the status quo for hospital infection hospital infection to provide a scientific basis. METHODS A cross-sectional survey was taken combined with the hospital bedside investigation and records investigation. RESULTS In 1033 cases,the prevalence rate was 3.87%,and the infected sites were the respiratory site,superficial incision,skin and soft tissue. Utilization rate of anti-bacterial drugs was 60.31%,the pathagen detection rate before treatment was low only 7.73%. CONCLUSIONS Prevalence rate survey method is simple and reliable,it may be the basic reflect of hospital infection. Further strengthening the management of invasive operations,regulateing the rational use of antibiotics status quo,improving the detection rate of pathogens and reduceing preventive medication and antibiotic usage are all evitable.

ObjectiveTo study the effects of dexamethasone local injection as an adjunctive therapy for Hashimoto thyroiditis (HT). Methods60 HT cases were equally divided into 2 groups at random. The patients in the control group were given euthyrpx while the patients in the treated group were injected dexamethasone in addition to the medicine used in the control group. The thyroid characters such as thickness, lymphocytic infiltration and changes of thyroid follicle were observed. The patients were followed up before treatment and 4, 12, 24weeks and 1 year after treatment. ResultsIn the treatment group, all thyroid glands turned significantly softer,and the mass became smaller compared with that in the control group. The pathology of thyroids indicated that lymphocytic infiltration decreased, local immune reaction was ameliorated, and no obvious hormone side effects were observed. ConclusionLocal use of dexamethasone can modify the structure and function of thyroid.

: ObjectiveTo compare the clinical significance of motor unit number estimates (MUNE) and conventional electromyogram (EMG) in the evaluation of neuromuscular disorders. MethodsUnder the model of MUNE or quantity of motor unit potential (QMUP), 53 patients with various neurogenic disorders were tested with EMG at extensor digitorum brevis, thenar, or hypothenar eminence. ResultsFor 8 patients with amyotrophic lateralizing sclerosis, large and long-duration polyphasic potentials were detected in needle electrode EMG tests, and the motor unit numbers reduced. For 45 patients with peripheral neuropathies, few distinctive features could not be detected by needle electrode EMG, but motor unit numbers reduced in 2 patients; spontaneous activities were the only abnormality in the other 2 patients, and there were no obviously abnormal changes in the configuration and size of motor unit potentials and in motor unit numbers; EMG tests revealed neurogenic features and motor unit numbers significantly reduced in the remaining 41 patients. ConclusionConventional EMG and MUNE can work for the diagnosis of neuromuscular disorders, and do better in combination.

Objective Linkage analysis were performed in 2 pure Chinese paroxysmal kinesigenic dyskinesia families to localize the locus of them. Method Microsatellites markers corresponding to pericentrometric region of chromosome 16 were used in parametric and nonparametrie linkage analysis for 27 members in the 2 pedigrees, haplotypes were constructed subsequently. Result The maximum LOD score and NPL score in the 2 families were all negative, P values were significantly larger than 0.05.No haplotype segregated with PKD phenotype was found. It showed no evidence of association with known PKD loci in both pedigrees, providing evidence for a novel PKD locus. Conclusion PKD is heterogeneous, a novel PKD locus may be in pure Chinese pedigrees.

Objective To study the repair function of united endothelial progenitor cells (EPC)transplantation on injured liver endothelium by bone marrow transplantation (BMT) conditioning.Methods C57BL/6 mice were divided into four groups randomly: normal control group, without any treatment; irradiation alone group, administered a total body irradiation(TBI) pretreatment, without BMT; (3) BMT alone group: C57BL/6 mice were infused with bone marrow mononuclearcells (MNC) 5 × 106/only through caudal vein not more than 4 h after the same TBI pretreatment as the irradiation alone group; united transplantation group: receiving the same way as the BMT alone group, but C57BL/6 mice were infused with EPC 5 × 105/only at the same time. Two, 4, 7, 14, and 21 days after the TBI, the changes of the liver weight were observed regularly. The histopathological examination of liver was done at the 4th, 7th, 14th, and 21st day after the TBI. Results In irradiation alone group, BMT alone group and united transplantation group the liver weight began to increase significantly on the day 2 and peaked at 14th day after the TBI, and the peaks were respectively (1.65±0. 15) times (P<0. 05), (1.61 ±0.06) times (P<0.05), and (1.11 ±0.40)times (P<0. 05) of those in normal control group. At the day 14, the liver weight in irradiation alone group, BMT alone group and united transplantation group began to decrease, and on the day 21 the liver weight in united transplantation group had been completely restored to normal level, however the liver weight in irradiation alone group and BMT alone group were still significantly heavier than that in normal control group (P<0. 05). Liver histopathological examination revealed that there were obvious sinusoidal endothelial cells (SEC) injury, hepatocyte edema and severe inflammatory cell infiltration in irradiation alone group, and on the day 7 the hepatocyte edema and necrosis were significantly worse than before, and almost no alive SEC were found. On the day 14 the injury of SEC in BMT alone group was lighter than before, but on the day 21 the injury had not returned to normal. On the day 7 the injury of SEC, hepatocyte edema and necrosis were alleviated in united transplantation group as compared with irradiation alone group and BMT alone group, and on the day 14 the injury had returned to normal basically. Conclusion The transplantation conditioning could damage recipient liver endothelium and the injury would persist, and united EPC infusion could repair the injured SEC following BMT.
