In recent years, there is some new recognition about the origin of prostatic carcinoma, prostatic carcinoma has been considered as a stem cell disease. Prostate cancer stem cells have close relationship with prostatic carcinoma formation, advancement, relapse, metastasis and drug resistance. As the development of science and technology continues, studies on the isolation and correlated phenotype identification of prostate cancer stem cells have lead us to further recognize prostate cancer stem cells, as well pave a new way for the diagnosis and therapy of clinical prostatic carcinoma.

Objective To explore the effects of the different doses of propofol for preventing postoperative agitation in chil-dren.Methods 60 children cases undergoing elective indirect inguinal hernia hernioplasty were selected in the Affiliated Hospital of Traditional Chinese Medicine,Luzhou Medical College from June 2011 to April 2011 and randomly divided into the group Ⅰ,Ⅱ andⅢ.The three groups were performed the general anesthesia with sevoflurane and postoperatively given 0.90% sodium chloride in-jection 0.10 mL/kg by intravenous injection,propofol 1.00 mg/kg by once intravenous injection and propofol 1.00 mg/kg by twice intravenous injection,respectively.The occurrence rate of postoperative agitation within 30 min was compared among 3 groups.The anesthesia recovery agitation score,improved Aldrete score,awakening time and time out of the operation room were also compared.

Objective To explore the expressions and.significancse of interleukin (IL)-10 and IL-18 in serum and tissues of patients with cervical intraepithelial neoplasias (CIN) and cervical cancer,and to analyze their relationships with clinical pathological characteristics and prognosis.Methods One hundred and eight patients' tissues and clinical blood samples (68 cases of CIN and 40 cases of squamous cell carcinoma) were enrolled in this study,including 25 with low-grade cervical intraepithelial neoplasias (CIN Ⅰ),43 with high-grade cervical intraepithelial neoplasias (CIN Ⅱ-Ⅲ),and 40 with invasive cervical squamous cell carcinoma (SCC);meanwhile,20 cases normal cervical tissues were enrolled.The expressions of IL-10 and IL-18 in cervical tissues and serum of the studied patients were measured by enzyme-linked immunosorbent assay and polymerase chain reaction.Meanwhile,second generation hybrid capture was used to detect human papilloma virus(HPV) DNA in cervical smears obtained from the studied patients with the different lesions.The relationships among IL-10 and IL-18 with HPV DNA and clinical prognosis were analyzed.Results The expressions of IL-10 and IL-18 in normal control serum were (212.75 ± 62.09),(187.84 ± 81.03)pg/ml respectively.The expressions of IL-10 in CIN Ⅰ,CIN Ⅱ-Ⅲ and SCC serums were (324.71 ±75.87),(397.43 ±68.56),(482.77 ± 104.05) pg/ml,with statistically significant difference (F =17.657,P =0.001).The expressions of IL-18 in CIN Ⅰ,CIN Ⅱ-Ⅲ and SCC serums were (305.53 ± 64.08),(392.74 ± 87.38),(499.86 ± 92.04) pg/ml,with statistically significant difference (F =13.309,P =0.003).The relative expressions of IL-10 in normal control,CIN Ⅰ,CIN Ⅱ-Ⅲ and SCC tissues were 0.99 ±0.01,3.24 ±0.68,7.32 ±0.99,13.24 ± 1.03,with statistically significant difference (F =21.694,P =0.000).The relative expressions of IL-18 in normal control,CIN Ⅰ,CIN Ⅱ-Ⅲ and SCC tissues were 0.98 ± 0.01,2.02 ± 0.84,7.01 ± 1.59,14.38 ± 2.10,with statistically significant difference (F =19.912,P =0.001).The expressions of IL-10 and IL-18 were positively associated with HPV infection (r =0.696,P =0.001;r =0.852,P =0.001).The median survival time of patients with high expressions of IL-10 was 9.74 months,which obviously shorter than those patients with low expressions of IL-10 (24.47 months),with statistically significant difference (x2 =21.363,P =0.001).The median survival time of patients with high expressions of IL-18 was 12.32 months,which obviously shorter than those patients with low expressions of IL-18 (22.88 months),with statistically significant difference (x2 =7.457,P =0.006).Conclusion High expressions of IL-10 and IL-18 are observed in patients with CIN and SCC,which can be used as biomarkers for predicting early cervical lesions.

BACKGROUND: The low survival rate of neuron cells is one of the main mechanisms of stem cell allograft, which might lead to the failure of allograft. Nuclear factor-KB (NF-kB) is one of main transcription factors for cell signaling transduction and participates in call proliferation and differentiation.OBJECTIVE: To study the differentiation of muscle-derived stem cells (MDSCs) into neuron-like cells induced by ciliary neurotrophic factor (CNTF) and Compound Salvia Miltiorrhiza Injection in vitro, and the expression of NF- kB.DESIGN, TIME AND SETTING: The experiment at cell molecular level was performed at the Oral Science Laboratory of the Second Affiliated Hospital of Liaoning Medical College from March to May 2008.MATERIALS: A total of 10 Sprague Dawley neonatal rats aged 7 days were supplied by Experimental Animal Center, Liaoning Medical University. CNTF (Sigma, USA) and Compound Salvia Miltiorrhiza Injection (Chiatai Qingchunbao Pharmacantical Co.,Ltd., China) were used in this study.METHODS: Rat MDSCs were harvested in vitro, pudfied by differential adherence and enzyme digestion, and incubated in 6-well plate. Samples in the induction group were incubated in DMEM containing CNTF for 24 hours. The medium was changed.Subsequently, samples were dnsed three times, and then incubated in serum-free DMEM supplemented with Compound Salvia Miltiorrhiza Injection for 5 hours. Samples in the control group were treated with serum-free DMEM.MAIN OUTCOME MEASURES: Neurofilament protein and NF-KB inhibitor protein expression were detected using reverse transcription-polymerase chain reaction (RT-PCR) and Westem blotting.RESULTS: No neurofilament protein expression was found in MDSCs before induction, and neurofilament protein-positive MDSCs were detected following induction. Results of gel electrophoresis and Westam blot showed that no significant differences in NF-kB inhibitor protein expression were determined in the control group, and NF-kB inhibitor protein expression was significantly decreased in the induction group after induction.CONCLUSION: CNTF and Compound Salvia Miltiorrhiza Injection could inhibit the activation of NF-kB and induce the differentiation of MDSCs into neuron-like cells.Zeng XY, Wang W, Sun L, Zhang L, Zeng LD.Differentiation of muscle-derived stem cells into neuron-like cells induced by ciliary neurotrophic factor and Compound Salvia Miltiorrhiza Injection in vitro.Zhongguo Zuzhi Gongcheng Yanjiu yu Linchuang Kangfu.2009;13(27): 5336-5340.

Objective: To study the effects of halothane and sevoflurane on myocardial function and energy metabolism. Method:The model of Langendorff perfused isolated rat heart was used to investigate the effects of halothane and sevoflurane on HR,LVEDP,LVDP,+dp/dt,-dp/dt and coronary flow(CF)before and after ischemia. and the myocardial ATP content were measured with HPLC before ischemia and 10 min after ischemia and at the end of reperfusion. Result: 1.5 MAC sevoflurane significantly increased CF in normal isolated rat hearts. Both halothane and sevoflurane differently depressed myocardial contratile function,increased normal myocardial energy storage. At 10th min of ischemia the decrease of myocardial ATP content was delayed by halothane and sevoflurane. At the end of reperfusion,the both anesthetics improved the recovery of myocardial function and matebolism,especially sevoflurane. Conclusion: Both anesthetics can protect myocardium from ischemic reperfusion injury through improving post-ischemic myocardial energy recovery.

BACKGROUND:Repeated injections or nasal spray of large doses of calcitonin can effectively prevent postmenopausal osteoporosis. Calcitonin should be taken for a long time.But the use of calcitonin is limited by the need for repeated protein administration, costly production methods and antigenicity. Gene therapy can provide effective economic therapeutic regimen for osteoporosis,and reduce side effect of drugs.OBJECTIVE:To describe the expression of human calcitonin produced in myoblasts and determine the effects of the recombinant protein on murine osteoblast cells.DESIGN:A gene-based controlled observational experiment.SETTING:Institute of Radiation Medicine,Fudan University.MATERIALS: The experiment was carried out at the Institute of Radiation Medicine, Fudan University from December 2005 to June 2006. Ten healthy SD fetal rats were selected from Institute of Radiation Medicine, Fudan University,Human Calcitoninsas monoclonal antibody was purchased from American Santa Cruz Biotechnology Company. L6 myoblast line was provided by Institute of Biochemistry and Cell Biology, Shanghai Institutes for Biological Sciences,Chinese Academy of Sciences. METHODS:The pcDNA3.0.-hCT liposome transfection mixture (transfection group) and empty vector pcDNA3.0 liposome mixture (control group) were added in the L6 myoblast medium, respectively.The expression and secretion of human calcitonin by myoblast cells were confirmed by enzyme-linked immunosorbent assay (ELISA),Western blot analysis and immunohistochemical analysis.1×10-14,1×10-13,1×10-12 mol/L recombinant human calcitonin and MEM were respectively added in myoblast medium. MAIN OUTCOME MEASURES:The proliferation and differentiation of rat myoblasts were observed by MTT and alkaline phosphatase (ALP).RESULTS: Human calcitonin was found by ELISA in the supematant of cell culture. Western blot and immunohistochemical analysis verified that human calcitonin could be expressed stably in myoblasts after transfection. Osteoblast proliferation and ALP activity were higher when recombinant human calcitonin was 1×10-14 and 1×10-13 mol/L than the control group (P＞0.05).It was significantly higher when the concentration was 1×10-12 mol/L than the control group (P＜0.05).CONCLUSION:The stable synthesis and secretion of biologically active human calcitonin can be achieved in myoblasts by gene transfection.Recombinant human calcitonin can enhance proliferation and differentiation of osteoblasts.

Objective To discuss the effective surgical treatment of intrahepatic lithiasis combined with high hepa-t ic duct strictures. Methods Two hundreds and sixteen cases of intra hepatic lithiasis and high hepatic duct strictures treated in this hospital fr om January 1993 to October 2002 were analysed retrospectively.Results One hundred and eighty- three cases underwent different selective operation by selected time; 33 case s complicated with acute obstructive suppurative cholangitis underwent emergency were performed single biliary drainage, in which 30 cases were re-operated. Th e operative procedure were: hepatic lobectomy,high cholangiotomy and plastic repair,exposure of hepatic duct of the 2nd and the 3rd order,and plastic re pair with own patch and choledochojejunostomy.Two hundreds and six cases w ere cured,the curative rate was 95.4%; 8 cases improved (3.7 %), and 2 cases died (0.9%).Conclusion The best effective surgical treat ment of intrahpatic lithiasis is hepatic lobectomy. Exposure of hepatic duct of the 2nd and the 3rd order is a satisfactory to release the hepatic duct str ictures and to clear the intrahepatic lithiasis. For patients with normal extr ahepatic bile duct and Oddi's function, plastic repair of bile duct with own patch is possible to keep the normal form and function. Cholang ioscopy may play an important role in the treatment of intrahepatic tr act lithiasis during operation.
