Objective:Use a new F-PCR method to develop a hepatitis C virus(HCV) diagnostic kit, test the kit through clinical trial and compare it with immunological method. Methods: Fluorescence PCR(F-PCR) is a method which combines PCR and fluorescence probe hybridization together to measure DNA/RNA. Because in-tube monitoring of fluorescence signal can be done to stand for the quantitity of PCR product. Electrophoresis and UV detection are eliminated, so after-PCR cross-contamination which causes false positive can be avoided. Results:A clinical diagnostic kit for HCV with this method is developed. 512 clinical serum samples were tested with this kit, using HCV FLISA kit from Abbott Co.and HCV Fluorescence RT-PCR kit from Biotronics Co. (B-PCR) as control. The results shows :positive rate is 30.5%,sensitivity 97.3 % and specificity 98.1% . Conclusion: F-PCR is obviously superior to ELBA, and higher than B-PCR in sensitivity. The specificity of those three kits have no statistic difference. F-PCR can be used to monitor RNA of HCV in serum, and could be useful for clinical diagnose and therapy effects monitoring.

ObjectiveTo discuss the effect of evidence-based nursing in improvement of unhealthy emotion and treatment compliance of patients undergoing painless gastroscopy. Methods134 patients from May 2008 to December 2010 undergoing painless gastroscopy were chosen as study object.According to voluntariness of the patients and their families,they were divided into the evidence-based nursing group (70 cases) and the routine psychological care group (68 cases).The satisfaction degree with nursing,unhealthy emotion,and the compliance during treatment process were evaluated with SAS and SDS.ResultsThe satisfaction degree of patients in the evidence-based nursing group was 92.86％,higher than 79.41％ in the routine psychological care group.No significant difference was shown in SAS and SDS score before treatment between two groups,but unhealthy emotion and treatment compliance after treatment significantly improved,and the improvement degree of the evidence-based nursing group was more evident. ConclusionsApplication of evidence-based care model in painless gastroscopy has more obvious advantages in improvement of unhealthy emotions and treatment compliance compared with routine nursing.It has more important value for clinical practice and is more conducive to improve the quality of life of patients.

Objective To prepare Curcumin liposome (Cur-L) and poly(2-ethyl-oxazoline)-cholesteryl methyl carbonate (PEOz-CHMC) was used to modified Cur-L and to evaluate their associated properties in vitro.MethodsEncapsulation efficiency and particle size were taken as evaluation indicators to optimize the formulation and preparation conditions of Cur-L by orthogonal test.The EE, particle size and shape of the liposomes were determined by sephadex G-50 mini-column centrifugation method, ZLS dynamic light scattering instrument and transmission electron microscopy (TEM), respectively.The release of the liposome in vitro was detected by The dialysis method.MTT assay was used to determine the cell inhibition of two Cur-L.ResultsThe optimized preparing method of Cur-L is as following: 1.56(w/w) as drug-lipid ratio, 5.1(w/w) as the ratio of mass of phosphatide and cholesterol, 7.4 as the pH of PBS buffer.The EE of Cur-L was (75.05±0.64)%, while the modification of PEOZ hasno influences on EE.Through TEM, PEOZ-Cur-L has aobviouslipid bilayer structure.The average particle diameter of PEOZ-Cur-L was 84.89 nm.In vitro release experiments showed that in 24h, the accumulative release rate of Cur-L is more than 70% with pH 7.4, while that of PEOZ-Cur-L was less than 25%.The cytotoxicity experiment showed that PEOZ-Cur-L can inhibit HCT116 Human colon cancer cells more effectively.ConclusionThe optimized preparing method of Cur-L is reasonable.PEOZ can provide stability to liposomes well and does not hamper its inhibitive effects.

Objective:To assess the clinical utility of a fluorescence in situ hybridization(FISH) assay as a non-invasive method for diagnosing and monitoring urothelial carcinoma(UC) in the upper urinary tract(UUT).Methods:Urine specimens from 63 consecutive patients with UUT-UC and 69 controls with benign disease were analyzed by means of cytology and FISH.For FISH analysis,labeled probes specific for chromosomes 3,7,and 17 and for the p16(9p21) gene were used to assess chromosomal abnormalities indicative of malignancy.Sensitivity and specificity of both techniques were determined and compared.The frequency of chromosomal aberrations of malignant cells from UUT-UC was also determined.Results:Of 63 patients with UUT-UC,FISH affords an overall sensitivity of 84.1%(53/63),the figure being 71.4%(20/28)for PTa and PT1 tumors,94.3%(33/35) for PT2-4 tumors.The sensitivities of urine cytology were 35.7%(10/28)for PTa and PT1 tumor,45.7%(16/35)for PT2-4 tumors,with an overall sensitivity of 41.3%(26/63).The sensitivities of the two methods for the low grade tumors were 80%(20/25)and 44%(11/25),and for high grade tumors were 86.8%(33/38)and 39.5%(15/38),respectively.Specificities for FISH and urine cytology were 91.3%(63/69)and 94.2%(65/69)respectively.Conclusion:According to the results,the sensitivity of FISH for the detection of UUT-UC is superior to that of urine cytology and the specificities of FISH and urine cytology are not significantly different.FISH can promote the diagnosis of UUT-UC,especially for the low stage and low grade cases,it may be a new promising non-invasive method for the diagnosis of UUT-UC.

Objective To explore the clinicopathological characteristics of non-muscle-invasive bladder cancer patients association with chronic kidney disease (CKD).Methods Between Jan 2009 and Dec 2010,536 patients (390 males and 146 females with mean age of 63 years) underwent surgical treatment at our institute for pathologically proven non-muscle-invasive bladder cancer.The clinical and pathological data of these patients were reviewed,and the relationships of these factors and CKD were analyzed.Presence of CKD was confirmed in patients with estimated glomerular filtration rate (eGFR)＜ 60ml/(min · 1.73 m2)calculated using the Modification of Diet in Renal Disease Study equation.Results Of the 536 consecutive cases,57 patients (10.6％) had CKD.Compared to the patients without CKD,there were more females and older patients in the patients with CKD (52.6％ vs 24.2％ and 69 years vs 62 years,both P ＜ 0.05).The patients with CKD proned to have multiple bladder tumor (71.9％ vs 50.9％,P ＜ 0.05) and synchronous upper urinary tract urothelial carcinoma (7.0％ vs 2.3％,P ＜0.05).The history of bladder cancer and upper urinary tract urothelial carcinoma were also predominated in these patients (43.9％ vs 29.0％ and 40.4％ vs 6.5％,both P ＜ 0.05).ConclusionConcurrent CKD in non-muscle-invasive bladder cancer patients is associated with greater risk of multiple tumors in urinary tract,particularly in female patients.

Objective To evaluate the early effect of Wallis interspinous dynamic stabilization system (Wallis system) in treatment of lumbar degenerative disease. Methods From January 2008 to Jan-uary 2009,21 patients(23 intervertebral spaces) with early lumbar disc herniation and lumbar spinal stenosis were treated with Wallis system. Four intervertebral spaces of L_(3-4) 19 intervertebral spaces of L_(4-5). Observed the time of total operation and implantation,the blood loss,and early recovery. The patients' visual analogue scale (VAS) and Oswestry disability index (ODI) scores were evaluated before and after operation. Results All patients were followed up for average (12.5 ± 0.4) months (7-18 months) after operation. The VAS and ODI scores at 7 days after operation dropped from (7.5 ± 1.5), (40.0 ± 2.0) scores before operation to (2.5 ± 0.5), (23.0 ± 1.5) scores (P < 0.01). Conclusion It is safe and easy to use Wallis system in the treatment of lumbar degenerative disease, with the advantage of mini-invasion and early effect.

Objective Subarachnoid hemorrhage ( SAH) is a devastating disease with a high mortality.This study was to in-vestigate the effect of Nrf2 on secondary brain injury following SAH and its action mechanism in mice. Methods SAH models were established in wild-type ( WT) and Nrf2 knockout ( KO) ICR male mice by injecting fresh blood drawn from the femoral artery into the pre-chiasmatic cistern.The animals were divided into four groups, WT sham, WT SAH, KO sham, and KO SAH.At 24 hours after modeling, the expression levels of malondialdehyde ( MDA) , GSH/GSSG, TNF-αand IL-1β, the volume of brain water, and content of Evans blue were measured, the activity scores obtained, and cerebral vasospasm of the anterior and middle cerebral arteries ( ACA and MCA) detected. Results At 24 hours, the expressions of MDA, TNF-α, and IL-1βwere (3.299 ±0.335), (1.187 ± 0.436), and (59.330 ±21.787) mg/g in the WT sham group, (4.339 ±0.328), (2.432 ±0.434), and (121.584 ±21.675) mg/g in the WT SAH group, (3.488 ±0.634), (1.170 ±0.312), and (58.497 ±15.608) mg/g in the KO sham group, and (5.335 ±0.499), (3.132 ±0.548), and (171.117 ±50.479) mg/g in the KO SAH group, markedly increased in the SAH groups as compared with the sham controls (P<0.05), while the GSH/GSSG levels were significantly higher in the former two groups than in the latter (0.553 ±0.100 and 0.375 ±0.068 vs 0.714 ±0.091, 0.761 ±0.114, P<0.01).The contents of brain water and Evans blue were (0.784 ±0.005) and (7.055 ±1.046) μg/g in the WT sham group, (0.808 ±0.004) and (7.230 ±1.192) μg/g in the WT SAH group, (0.784 ±0.004) and (9.620 ±1.290) μg/g in the KO sham group, and (0.819 ±0.004) and (11.628 ±1.040)μg/g in the KO SAH group, remarkably increased in the SAH groups in comparison with the sham groups (P<0.05).The apoptosis rate 8.916 and 82.100 ±6.870 vs 70.833 ±8.750 and 51.767 ±13.006), ACA radius/wall thickness value (13.885 ±3.360 and 14.212 ±3.2545 vs 8.024 ±2.780 and 6.861 ±2.702), MCA radius/wall thickness value (18.648 ±2.893 and 19.435 ±2.775 vs 6.337 ±3.993 and 5.107 ±3.805), and activity score (2.733 ±0.450 and 2.767 ±0.430 vs 1.967 ±0.928 and 1.433 ±0.679) (all P<0.01). Conclusion Nrf2 knockout increases oxidative stress and inflammatory reaction following SAH and consequently aggravates secondary brain injury.Nrf2 has a protective effect against SAH-induced brain injury.
