Objective To explore the safty and feasibility of transrectal ultrasound guided transperineal seminal vesicle biopsy in the evaluation of clinical staging of prostate cancer.Methods Retrospectively study 57 suspected prostate cancer patients with seminal abnormality during 2010.7-2015.1,age ranged from 50 to 78 years,average 65 ±7 years,serum total prostate specific antigen (tPSA) 3.2-131.1 μg/L, average (23.7 ± 11.3) μg/L.Twenty-two cases had palpable prostate nodules through rectal examination.All the 57 patients underwent ultrasound and template guided transperineal prostate and seminal vesicle puncture biopsies.Results Forty-four cases out of 57 found prostate cancer cells in biopsies, and 32 cases had seminal vesicle invasion (positive group) while the other 12 were negative.Twenty cases had been performed prostatectomy in the positive group and their post-operative pathological examination all showed prostate cancer with seminal vesicle invasion.Eleven cases in the negative group had been performed prostatectomy ,and 2 cases showed seminal vesicle invasion.The clinical stages of all cases in the positive group were considered as T3b both pre-operatively and post-operatively.In the negative group however, 11 cases were considered as T2 stage pre-operatively,while 2 cases were increased to T3b stage post-operatively.The sensitivity of puncturing seminal vesicle was 91％ (20/22) ,specificity was 100.0％ (9/9).Positive predictive value was 100.0％ (20/20),while negative predictive value was 82％ (9/11).All the 57 cases did not present fever after puncture biopsies, while 23 cases presented hematuria (40％) ,20 cases presented hemospermia (35％) and 1 case presented urinary retention (2％).Conclusions Transrectal ultrasound-guided transperinealseminal vesicle puncture is safe and reliable, it helps to improve the accuracy of pre-operative staging.

Objective:To observe the effects of continuous light exposure on skeletal muscle fiber type transformation and lipid metabolism, and to explore its internal relationship.Methods:Mice were randomly divided into normal light group and 24-hour continuous light group by random number table. The serum and skeletal muscle lipid content and urine 6-sulfatoxymelatonin(6-SML)level were detected by ELISA. The expression of circadian clock and lipid metabolism related genes mRNA were observed by realtime PCR. The muscle fiber type and lipid deposition were evaluated by tissue immunofluorescence as well as oil red O staining.Results:Compared with the normal light group, the level of 6-SML in urine at night decreased( P<0.05), and the expression level and rhythm of brain and muscle ARNT-like protein 1(Bmal1), circadian locomotor output cycles protein kaput(Clock), and period 2(Per2)mRNA in the skeletal muscle changed in continuous light group. In addition, the body weight, blood lipid, free fatty acid, and triglyceride contents of skeletal muscle in continuous light group increased significantly( P<0.05 or P<0.01), the expression of carnitine palmitoyltransferase 1b (Cpt1b)mRNA, the key enzyme of fatty acid oxidation, decreased significantly( P<0.05), while the expression of stearoyl-CoA desaturase(Scd1)mRNA, a lipid synthesis related gene, increased significantly( P<0.01). Further immunofluorescence analysis showed that the proportion of slow muscle fibers decreased and that of fast muscle fibers increased in continuous light group(both P<0.05). Conclusion:The process of ectopic deposition of lipid in skeletal muscle in mice induced by continuous light exposure may be related to the remodeling of skeletal muscle fibers.

OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.

METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.

RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).

CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

The shape and structure of granules are controlled by the granulation process, which is one of the main factors to determine the nature of the solid dosage forms. In this article, three kinds of granules of a traditional Chinese medicine for improving appetite and promoting digestion, namely, Jianwei Granules, were prepared using granulation technologies as pendular granulation, high speed stirring granulation, and fluidized bed granulation and the powder properties of them were investigated. Meanwhile, synchrotron radiation X-ray computed micro tomography (SR-µCT) was applied to quantitatively determine the irregular internal structures of the granules. The three-dimensional (3D) structure models were obtained by 3D reconstruction, which were more accurately to characterize the three-dimensional structures of the particles through the quantitative data. The models were also used to quantitatively compare the structural differences of granules prepared by different granulation processes with the same formula, so as to characterize how the production process plays a role in the pharmaceutical behaviors of the granules. To focus on the irregularity of the particle structure, the box counting method was used to calculate the fractal dimensions of the granules. The results showed that the fractal dimension is more sensitive to reflect the minor differences in the structure features than the conventional parameters, and capable to specifically distinct granules in structure. It is proved that the fractal dimension could quantitatively characterize the structural information of irregular granules. It is the first time suggested by our research that the fractal dimension difference (Df,c) between two fractal dimension parameters, namely, the volume matrix fractal dimension and the surface matrix fractal dimension, is a new index to characterize granules with irregular structures and evaluate the effects of production processes on the structures of granules as a new indicator for the granulating process control and optimization.

OBJECTIVETo investigate the efficacy and safety of secreted interferon in treatment of chronic hepatitis B.

METHODSA multi-center randomized open-label controlled clinical trial was carried out. The patients of the study group were treated by secretory human interferon alpha-2a, and the patients of the control group were treated with an ordinary interferon.

RESULTSALT normalization rate in the secreted interferon group was 48.3% and it was higher at the end of treatment than that of the control group, but there was no difference between the two groups at the end of the follow-up. HBV DNA dropped more in the study drug group, but there was no difference in the normalization rate between the two groups. HBeAg seroconversions in secreted interferon group and in the control interferon group were 19.0% and 18.4% respectively. The safety of the two types of interferon was satisfactory.

CONCLUSIONSSecreted interferon was superior to ordinary interferon in ALT normalization and HBV DNA drop at the end of treatment in chronic hepatitis B patients, but there was no difference at the end of the follow-up. There was also no difference in HBeAg negative and HBeAg seroconversion between the two groups.

OBJECTIVETo investigate the clinical features, treatment modalities and the prognosis of advanced neuroblastoma in children.

METHODSThe medical records of 63 children with stage III or IV neuroblastoma from January 1996 to December 2005 were retrospectively reviewed. Sixty patients were treated by tumor resection and (or) chemotherapy and (or) radiation. Fourteen out of the 60 patients received another autologous peripheral blood stem cell transplantation.

RESULTSOf the 63 patients with advanced neuroblastoma, the male/female ratio was 2.7:1 and the median age at diagnosis was 4 years old. Most of the initial symptoms included pyrexia, abdominal pain, abdominal mass, and leg or articular pain. Primary tumor sites were adrenal (38%), retroperitoneal (35%), mediastinal (17%), pelvic (6%) and cervical (2%). The sites of metastasis at diagnosis included local (41%) and (or) distant (37%) lymph nodes, bone marrow (60%), bone (46%) and liver (16%). The median survival time of the 63 patients was 32.7 months. The 2-year survival rate was 44.3%. Statistical analysis demonstrated that unfavorable survival prognostic factors were the following: age > 1 year at diagnosis (P < 0.05); serum neuro-specific enolase > 100 mg/L (P < 0.05); serum lactic dehydrogenase > 1500 U/L (P < 0.01); serum ferritin >150 mg/L (P < 0.05). The overall survival period of the patients was prolonged through total resection of the primary tumor (P < 0.05). Intensive chemotherapy in combination with autologous peripheral blood stem cell transplantation could also result in a prolonged overall survival period (P < 0.01).

CONCLUSIONSNeuroblastoma with advanced stages often presents with various clinical manifestations and has a poor prognosis. It is beneficial to improve the prognosis of neuroblastoma through an early diagnosis and a comprehensive therapy including total resection of the primary tumor, autologous peripheral blood stem cell transplantation and intensive chemotherapy.
