OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

Aim According to various target sites of HLA-E mRNA,to design and synthesize 3 pieces of HLA-E siRNA chain,to compare quantitatively their efficiency of silencing gene in BEL-7402 with HLA-E(+)in order to select the dominant siRNA.Methods The hepatocarcinomal BEL-7402 cells,induced by 5×10~5 IU·L~(-1) IFN-γ,expressed HLA-E(+) and was pured by flow cytometry selecting as target cells for research.3 pieces of specific siRNA(A,B,C group)were designed and chemically synthesized,then the concentration of which(0.1 mmol·L~(-1))was respectively transfected through Lipofectamin 2000 into target cells.After 48 h,the gene silent effect on HLA-E gene in A,B and C groups was quantitatively observed by cytoimmunofluorence,flow cytometery,Western blot and real-time PCR,as well as on NK cytotoxicity to target cells tested by NK killing rate.Results Compared with those of control or non-specific siRNA group,HLA-E antigen,protein product,HLA-E mRNA and HLA-E molecule on cell surface were statistically down-regulated in A,B,and C group(P<0.01),whose were silenced more (above 90%) in B or C group than in A group (P<0.01).The NK killing rate in A,B and C groups was dominantly improved(P<0.01),which in B or C group was higher than in A group (P<0.01).Conclusion The targeted siRNA can specifically and high-efficiently silence HLA-E expression in hepatocarcinomal cells,and may keep them from immunoescape through non-classic HLAⅠ pathway to imply new strategy for hepatocarcinomal gene-immunotherapy.

Objective To understand the mortality rate and cause of the injury in Hebei province in order to provide scientific theoretical basis for drawing up effective prevention measures.Methods The injury deaths data was collected from 18 surveillance spots in Hebei province during 2004—2005,and the injury was classified with ICD-10 and the corresponding mortality rates were calculated.Results The average injury mortality rate was 54.02/100 000(the age-adjusted rate was 51.62/100 000).It was the 5 th-ranked cause of death.The leading five causes of injury were traffic injury by motor vehicles, traffic injury by non-motor vehicles,suicide,poisoning and fall,which accounted for 23.96%,22.05%,13.10%,11.99%, 5.62%,respectively.The average injury mortality rate in rural(58.48/100 000)was higher than in urban(31.60/100 000)(?~2= 255.82,P

Objective To explore the construct validity of the Chinese version of Kinesthetic and Visual Imagery Questionnaire (KVIQ)-20 and KVIQ-10 in stroke patients and normal people. Methods From October, 2012, to March, 2014, 60 stroke patients and 60 nor-mal people with matched gender and age participated in this study. They were assessed with the Chinese version of KVIQ-20 and KVIQ-10. The construct validity was investigated with factor analysis. Results Two factors were extracted from KVIQ-20 for stroke patients after vari-max rotation, that accounted for 62.4%of the variance, as well as KVIQ-10 with 67.6%of the variance. Two factors were extracted from KVIQ-20 for normal people with 76.1%of the variance, as well as the KVIQ-10 with 69.6%of the variance. The factors could be named as visual imagery and kinesthetic imagery. Conclusion The Chinese version of KVIQ-20 and KVIQ-10 has good construct validity for assess-ing motor imagery from the dimensions of visual imagery and kinesthetic imagery, both in patients with stroke and normal people.

ObjectiveTo explore effects of food viscosity and sex on hyoid motion during swallowing in normal elder.MethodsVideofluoroscopic studies were done in 60 healthy elder. Hyoid motion during swallowing food with different viscosity was measured.ResultsOlder male had longer movement duration, greater amplitudes of upward and forward movement than older female (P<0.05). Amplitudes of upward movement in jam thick swallow and bread thick swallow were greater than that in liquid swallow (P<0.01). Bread thick swallow had the longest movement duration; liquid swallow had shortest movement duration.ConclusionThe hyoid bone moves both upward and forward during swallowing, the amplitude of upward displacement is highly variable and influenced by food viscosity. The duration and amplitude of hyoid motion in male or female are different.

Objective To evaluate the embolic effect on rabbits arteries using self-made copper plated platinum coil.Methods 1 7 New Zealand Big Ear Rabbits were selected.Unilateral subclavian artery or carotid artery was embolized with self-made secondary level copper plated platinum micro-coils (experimental group)through 3F-catheter.Contralateral subclavian artery or carotid artery was also embolized using secondary level platinum micro-coils (control group)as a control.The level of serum copper ions and the liver and renal function were recorded during different intervals before and after embolization.The arteriography and the tissue his-tology were observed respectively during different intervals after the embolization.Results 1 5 of 1 7 rabbits were embolized success-fully.After embolization,the level of serum copper ions increased in 2 weeks(P <0.05).However,it returned to preoperative level after 4 weeks (P >0.05).The liver and renal function was similar to that of the preoperation after 2 weeks.After embolization,an-giography showed that vascular embolization effect between two groups was not significantly different at 10 min and 30 min;howev-er,the embolization effect of experimental group was superior to that of control one (P <0.01)at 3 days and 1 week,2 weeks,4 weeks,6 weeks and 12 weeks.Pathological results showed that there were a lot of thromboses inside,outside and around the copper coil.Few thromboses appeared around platinum coil in control group.The thrombosis situation in experiment group was better than that in control one (P <0.01).However,no significant difference in inflammatory cell infiltration between two groups was found. Conclusion Self-made secondary level copper plated platinum coil has good physical property,rememorability,flexibility and con-trollability.

Objective To induce mouse embryonic stem(ES)cells to differentiate into insulin-secreting cells by means of a 5-step model system.Methods E14.1 mouse ES cells were cultured in the presence of leukemia inhibitory factor(LIF)for 2 days(step 1),then the cells were cultured in hanging drops to form embryonic bodies(EBs)and the resulting EBs were cultured in suspension for 6 days in the presence of basic fibroblast growth factor bFGF(step 2).Subsequently the EBs were cultured in the medium containing glucagon- like peptide 1(GLP-1),hepatocyte growth factor(HGF),nerve growth factor(NGF)and nicotinamide for 10 days(step 3).After that,the EBs were dissociated into single cells,and the cells were cultured in monolayer in the presence of GLP-1,betacellulin,activin A,bFGF and nicotinamide for 10 days(step 4).Finally,the cells were cultured in low-glucose medium containing nicotinamide for 4 days(step 5).Insulin and some other islet- related genes expressions were investigated using RT-PCR and insulin expression was also investigated by DTZ- staining and immunohistochemistry.The percentage of insulin-secreting cells was evaluated by flowcytometry and insulin concentrations were measured by RIA.Results mRNA expression of insulin became visible at step 3 and more evident at step 5.Additionally,at step 5,mRNAs of glucagon,somatostatin,pancreatic polypeptide(PP), pancreatic duodenal homeobox 1(PDX-1),beta-cell E box transactivator 2(Beta2)and neurogenin 3(Ngn3) were detected.DTZ-staining positive cells and insulin immunohistochemical staining positive cells were observed. The percentage of insulin-positive cells was(24.0?2.5)%(n=6).In the presence of 5.6 mmol/L and 25 mmol/L glucose,insulin concentrations were(0.05?0.01)?g/L and(0.13?0.02)?g/L respectively(n= 6).Conclusion E14.1 mouse ES cells can be induced to differentiate into insulin-secreting cells by the 5-step model system.Insulin-secreting cells can release insulin into culture medium when treated with glucose,and insulin concentrations increase with rising concentration of glucose.
