Objective To investigate the availability and mechanism of recombinant adenovirus vector expressing wild type p53 in gene therapy of prostate cancer. Methods Prostate cancer cell line PC3M was cultivated and recombinant adenovirus vector expressing wild type p53 was added to the media. Then the levels of proliferation and apoptosis were detected and changes of bax were exa mined . Results AdCMVp53 is effectively transfected to the cells. The transfecting ratio is 95%. In the cells transfected with AdCMVp53, the level of proliferation decreased. Tested by BrdU, the absorbance rate decreased from 1.454 in the control group to 0.496 in the experimental group( P

Objective To explore the classification and risk factors of nocturia in patients with benign prostatic hyperplasia (BPH). Methods The 120 males aged 60 years old and over were enrolled who were first diagnosed as BPH or had ceased the BPH medication for at least 3 months.The patients were divided into six groups according to the nocturnal voiding episodes estimated according to the international prostate symptom score (IPSS). All 120 males were inquired about general information and medical histories. The time and volume of intake and voided urine were recorded for 72 hours. The indexes of prostate and bladder function in all cases were also examined and recorded. Results The incidence of nocturia in our study was 79.2%, the incidence of nocturnal polyuria and overactive bladder were 3.3% and 10.8%, respectively. The quality of life was affected by the duration between the time of patients' going to bed and the first time getting up at night. After excluding the cases of nocturnal polyuria and overactive bladder, statistical analysis indicated that the age, and residual urine volume of the bladder were positively associated with nocturia frequencies (NF), the nocturnal voiding volume negatively with NF, while the prostate volume and peak flow rate were not associated with NF. Drinking volume in 24-hours affected the nocturia (P<0. 01). Conclusions Nocturia is a common complaint in elderly males with BPH and significantly affects the quality of life. The age and the storing function of bladder are more important factors as compared with prostate hyperplasia itself.

Objective To improve the finding of prostate cancer (PCa) and prevent the unnecessary biopsies, we select proper patients for biopsy and analyze. Methods The retrospective study included 258 patients who were biopsied for suspected early PCa. Then we analyse how the age, prostate volume, PSA, transrectal ultrasound sonography (TRUS) and MRI affect the finding of prostate cancer. Results Altogether 146 BPH and 112 prostate cancer by biopsy were detected. Positive ratio of biopsy was increased with the age or PSA increases but has no relationship with the prostate volume. Combination with digital rectal examination, PSA and TRUS, the positive ratio was improved and unecessary biopsies were avoided. The detective rate reached 84.6% when all of these three parameters were positive. The sensitivity of MRI was 98.3% but specificity was only 22.4%. The total efficacy was 21.8%. Conclusions The effect of DRE, PSA and TRUS in the screening of prostate cancer should be emphasized. However, importance of MRI is limited for the early detection of PCa.

Thirty six patients aged 50-70 years with benign prostatic hyperplasia (BPH) received doxazosin and desmopressin treatment for 4 weeks.After treatment the International Prostate Symptom Scores (IPSS) and Quality of Life (QoL) scores of patients were significantly improved (17.4 ± 2.5 vs.11.8 ± 1.1 and 3.9 ±0.6 vs.1.8 ± 1.3,respectively;both P < 0.01).The nocturia frequency was decreased from 4.6±1.5 to 2.1±1.6 (P<0.01);nocturnal urine output from (564±73) to (348±45) ml (P<0.05);the hours of undisturbed sleep increased from (88.6 ± 17.5) min to (146.2 ± 12.8) min (P <0.05).There were no significant differences in serum levels of sodium,potassium and chlorine,and osmoticpressure before and after treatment.The results indicate that doxazosin combined with desmopressin is safe and effective for treatment of nocturia in patients with BPH.

ObjectiveTo investigate the clinical application value of enzyme-linked immunosorbent assay (ELISA) and time-resolved fluorescence analysis(TRFIA) and latex immune chromatography (GICA) in detecting hepatitis B serum markers.MethodsOne hundred and forty-five suspected patients of hepatitis B were detected serum markers of hepatitis B by ELISA,TRFIA and GICA method,and the results were compared and analyzed.ResultsWhen TRFIA method was as gold standard,the positive coincidence rate of ELISA and GICA method in HBsAg,HBeAb,HBcAb was 71% (57/80),45% (36/80),and in HBsAb,HBeAb,HBcAb was 33%( 1/3),0 (0/3),and there were significant differences between two methods (P<0.05 ) ; the others were no significant differences (P > 0.05 ).There was significant difference in the sensitivity of HBsAg between ELISA method and GICA method (P < 0.05 ),but there was no significant difference in HBsAb,HBeAg,HBeAb,HBcAb(P > 0.05 ).There was no significant difference in the specificity of HBsAg,HBsAb,HBsAg,HBeAb and HBcAb between ELISA method and GICA method (P >0.05).There was significant difference in HBsAg among three methods(P <0.05),but there was no significant difference between ELISA method and TRFIA method (P>0.05),and there was significant difference between GICA method and TRFIA method (P<0.05).There was no significant difference in HBsAb,HBeAg,HBeAb and HBcAb among three methods (P > 0.05 ); there was significant difference in both HBsAb and HBeAb positive among three methods (P < 0.05),and there was significant difference between ELISA method,GICA method and TRFIA method (P< 0.05).ConclusionTRFIA method has supreme measuring range,sensitivity and specificity supreme,but the price is higher;ELISA method is in the intermediate level of three methods and price is cheap,and it as well as TRFIA is suitable for the batch detection; GICA accuracy is low,but quick and simple,it is more suitable for the complement of the first two methods.

Objective:To construct the Helicobacter pylori infected C57BL/6 mice model to observe the activation of NOD1/NF-κB signaling pathways in the gastric tissues,and study its roles in inflammatory response during Hp infection.Methods:6-8 week-old C57BL/6 mice were randomly divided into two groups,the Hp infection group and the control group,and mice were given by gavage every 48 h for five times with Hp or PBS,respectively.All the animals were sacrificed at different time point and the gastric tissue were stained with hematoxylin-eosin( HE);The mRNA expression of NOD1 and RIP2 in gastric tissues were examined by RT-PCR;Levels of IFN-βand IP-10 in mice serum were assessed by ELISA;Nuclear translocation of p65 in gastric tissue was detected by Western blot.Results:Hp infection elicits an inflammatory cell response,glands in gastric tissue were reduced or atrophic,as compared with that in the control group.The levels of IP-10 and IFN-βincreased in the model group, and peaked at 16 weeks after Hp infection.Hp infection increased the mRNA expression of NOD1 and the p65 content in nuclear between 24-120 h(P<0.05),and the highest level at 48 h,subsequently the expression levels were began to decrease.The mRNA expression level of RIP2 was up-regulated after Hp was administrated, peaked at 48 h and declined after 72 h.However, the expression levels would rise again at 120 h.Conclusion: Hp infection can activate the NOD1/NF-κB signaling pathways and induce the production of IFN-βand IP-10 in gastrics of mice.

Objective To investigate the evaluative meaning of the traditional Chinese medicine (TCM)sweat detector and temperature detector to atheriosclerosis obliterans (ASO).Methods 68 limb plantar of ASO patients and 20 left plantar of healthy subjects were tested by TCM sweat detector and temperature detector to observe the differences of sweating rate and temperature between the two groups.Results ①Sweating rate and temperature of ASO patients' limb plantar showed different graphic morphology from that of healthy control group.The sweating rate of patients was worse than that of healthy subjects in responding to external stimuli.②ASO patients'limb plantar baseline values of the sweating rate and temperature were lower than that of healthy subjects,and the result was statistical significant (P<0.01).Conclusion Data obtained from TCM sweat detector and temperature detector can be used to distinguish ASO patients from healthy people.
