Objective To compare the clinical efficacy and safety between transurethral plasma kinetic enucleation of prostate(TUPKEP) and transurethral resection of prostate(TURP) on benign prostatic hyperplasia(BPH). Methods One hundred and forty two BPH patients were divided into two groups:TUPKEP group (72 cases) and TURP group (70 cases). Seventy two cases aged 52-90 years[mean age (70. 5±7.6) years] with prostate weight of 27-126 g [mean weight (75. 6±10. 3)g] underwent TUPKEP, and seventy cases aged 51-87 years[mean age (70. 2±6. 8) years] with prostate weight of 25-118 g[mean weight (73.8±9.9)g] underwent TURP. There were no significant differences in age, weight of the prostate, international prostate symptom score(IPSS), residual urine volume(RUV) ,maximum urinary flow rate (Qmax) and quality of life (QOL) scores between the two groups before operation (t=0. 2873, 1.0612, 1. 0832,0. 9522,0. 0000, 1. 0774;P=0. 7743,0. 2904, 0. 2806,0. 3426,1. 0000,0. 2832). The operative time, intraoperative blood loss, the preserved time of installing catheter, hospitalization time, postoperative morbidity rate and efficacy were compared between the two groups. Results The operation success rates were 100. 0% (72/72) in TUPKEP group and 98.6% (69/70) in TURP group. The average operation time were (46.2±6.4)min and (58. 4±9. 6)min (t±8. 9404, P=0.0000), and the mean intraoperative blood loss were (105.9± 12.2)ml and (148.6±14.3) ml(t=19. 1608, P=0.0000) in TUPKEP and TURP groups respectively. The mean preserved time of installing catheter were (3. 5±1.0)d and (5.0±1.0)d(t= 8. 9364, P=0. 0000), and the average hospitalization time were (5.1±1.9) d and (7.0±2.6) d (t= 4. 9819,P=0.0000)in the two groups, respectively. In TUPKEP group, there was one case of temporary urinary incontinence, two cases of secondary prostate hemorrhage and one case of external orifice stricture of urethra, with a complication rate of 5.56%. In TURP group, there were two cases of transurethral resection syndrome (TURS), one case of urinary extravasation, two cases of temporary urinary incontinence, three cases of secondary prostate hemorrhage and two cases of external orifice stricture of urethra, with a complication rate of 14.29% . Compared with preoperation, Qmax was obviously increased and IPSS,RUV, QOL scores were decreased after follow- up for 3 months, but there were no significant differences in these parameters between the two conditions(t=1. 1131,0. 2543,1. 2959,0. 7252;P=0. 2676,0. 7996,0. 1971,0. 4696). Canclusions TUPKEP and TURP have similar efficacy in the treatment of BPH, but TUPKEP is a method with shorter operation time, less blood loss, lower postoperative complication rate and more safety than TURP.

Objective To investigate the correlation of hepatitis B virus (HBV) markers between umbilical cord blood and maternal serum.Methods A total of 340 HBsAg positive mothers who delivered at the Third People' s Hospital of Changzhou during August 2009 and November 2010 were included in the study.HBV markers in the maternal serum before childbirth and umbilical cord blood after birth were quantitatively detected.The neonates received 3 doses of hepatitis B vaccine and 2 doses of hepatitis B immunoglobulin (HBIG),and followed up for 12 months.Measurement data were expressed as median (M),and Kruskal-Wallis test and Spearman correlation analysis were performed.Results There were 175HBeAg-positive and 165 HBeAg-negative mothers,and a total of 341 infants were delivered.The positive rates of HBsAg,anti-HBs,HBeAg,anti-HBe and anti-HBc in maternal serum were 100.00％,0.0％,51.47％,38.82％ and 99.41％,respectively; while those in umbilical cord bloods were 14.66％,0.59％,26.69％,39.88％ and 95.31％,respectively.HBsAg concentration in maternal serum of HBsAg-positive umbilical cord blood group was higher than that of HBsAg-negative umbilical cord blood group (419.40∶ 387.95,x2 =4.592,P ＜ 0.05) ; while HBsAg concentration in umbilical cord blood of HBeAg-positive maternal serum was higher than that of the HBeAg-negative maternal serum group (0.04 ∶ 0.01,x2 =5.674,P ＜ 0.05).Anti-HBe and anti-HBc in umbilical cord blood were positively correlated with those in maternal serum (r =0.838,0.764,P ＜ 0.01).Seven out of 62 (11.29％) infants were infected with HBV in HBeAg-positive maternal serum group; while no infant infected in HBeAg-negative matemal serum group.Conclusion The higher maternal serum HBsAg concentration,the greater the risk of perinatal transmission,and infants born by HBeAg-positive mothers are of high risk of HBV infection.

ObjectiveThe aim of this study was to investigate the professional cognitive level and its influencing factors of fresh nursing students in Yunnan,in order to provide a basis for nursing education workers, improve the situation and put forward a series of interventions.MethodsA questionnaire survey was done among 623 fresh nursing students in 5 universities of Yunnan province,and the data were collected and analyzed using the descriptive analysis and chi-square test of software SPSS22.0.Results There were 313 peoples choose nursing for easy future employment in qualified 599 questionnaires. The professional cognitive level in Yunnan was not comprehensive compared with other provinces,and the ratio of the nursing mission and etc were lower than other provinces with statistical significance(P < 0.05). However,there were 50 people(40.98%)would like to choose other major of 122 people who come from other provinces,which was higher than that of Yunnan (34.98%). There were 324 students(63.11%)were proud of nursing,327 students(63.70%)think nursing have a good development prospect who received the freshmen entrance education,which were higher than 35.62% and 42.47% of who could not receive the freshmen entrance education,with a statistical significance(P < 0.05). ConclusionSchool should reinforce the new students entrance education and professional publicity to cultivate the professional emotion of nursing freshmen.

Objective To investigate cognitive function and behavior characteristics in the childhood onset schizo?phrenia patients with or without obsessive-compulsive symptoms. Methods One hundred forty-nine schizophrenia chil?dren were recruited and 72 healthy children served as children control group. According to the Schedule for Affective Dis?orders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), the patients were fur?ther divided into two groups, the children with obsessive-compulsive disorder group (70 cases) and the children without obsessive-compulsive disorder group (79 cases). All the children were retrospectively surveyed and the Achenbach’s Child Behavior Check-list (CBCL) was used to assess their social competence and behavioral characteristics at the age from 6-year-old to 10-year-old. The cognitive function was estimated with WISC, STROOP color and word test, trail making test, visal spatial memory test and maze test. Results Compare to the control group, the CBCL factor scores of behavior problems were higher (P<0.01), social ability factor scores were lower (P<0.05) and all factor scores in the cog?nitive function tests were lower (P<0.05) in the two patients groups. Compare to the patients without obsessive-compul?sive symptoms, the CBCL factor scores of the school situation (P<0.01), splitting force (P<0.01), and physical complaints (P<0.01) were significantly higher and the scores were significantly lower in the test of common sense (P<0.01), wood (P<0.01), STROOP (P<0.01) and BVMT-R (P<0.01) in those with obsessive-compulsive symptoms. Correlation analysis showed that social competence total scores were positively correlated with similarity in the patients with obsessive-com?pulsive symptoms (r=0.31, P<0.01);while behavior problems total scores were negatively correlated with wood (r=-0.31, P<0.01) and patchwork (r=-0.32, P<0.01) in the patients without obsessive-compulsive symptoms. Conclusion The schizophrenia children with obsessive-compulsive symptoms have more behavioral problems in pre-symptom period and their cognitive dysfunction are more severe following onset of the disease. Cognitive function is related to behavioral prob?lems and social competence in the schizophrenia children with or without obsessive-compulsive symptoms .

Objective To construct cDNA entry library and cDNA expression library of Armillifer agkistrodontis (A.) nymphs and make a preliminary immunoscreening for the cDNA expression library.Methods The nymphs were collected from the Kunming mice infected experimentally with A.agkistrodontis eggs and the total RNA were extracted from the nymphs using TRIzol Reagent.After purifying the mRNA,the synthesized cDNAs were cloned into the donor vector pDONR222 by BP reaction of Gateway technology and the recombinants were transformed into the DH10B cells by electroporation,the cDNA entry library was obtained.Next,the expression vector pDEST17 was ligated with entry clones by LR reaction,and the recombinants were transformed into the BL21 (DE3) cells.Hence,the cDNA expression library was constructed.Then,the expression library was immunoscreened with the mixed sera of mice infected with A.agkistrodontis,and the insertions of positive clones were sequenced.After that,the open reading frame(ORF) of positive slone sequence,the homology of the screened genes and their encoded proteins were analyzed by Finder and BLAST (basic local alignment search tool) program of National Center of Biotechnology Information(NCBI),and the discovered new genes were submitted into the GenBank.Besides,the physico-chemical properties,secondary structure and B cell epitopes of encoded proteins were also analyzed by bioinformatics software.Results The average titer and total clones of the cDNA entry library were 1.45 × 105 CFU/ml(colony-forming unit,CFU) and 1.74 × 106 CFU,respectively,and the range of fragment length of the inserted cDNA was between 0.2-4.0 kb,with an average of 1.4 kb.The total clones of cDNA expression library were 1.00 × 105 CFU,and the fragment length of the inserted cDNA was between 0.3-2.2 kb,with an average of 1.0 kb.Five positive clones,coded S1,S5,A1,D1 and F1,respectively,were obtained through preliminary immunoscreening.The sequence and homology of the five positive clones were sequenced and analyzed by BLAST program.No significant similarities were found in pentastomida species,which meant that they were all novel genes of A.agkistrodontis.The gene sequences were submitted to GenBank,with the accession number from JQ180451 to JQ180455.Also,results obtained by bioinformatics software showed that the predictive encoding proteins were all potential to be valuable recombinant diagnostic antigens.Conclusions The cDNA library of A.agkistrodontis nymphs is successfully constructed,and five new genes of A.agkistrodontis are discovered.The establishment of cDNA library and the discovery of the new genes will lay a foundation for further studying the gene functions and screening the immunodiagnostic antigens.

OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.

Objective To investigate the ability of induction of specific cytotoxic T lymphocytes (CTL) stimulated by dendritic cells (DCs) co-transfected with MUC1 and survivin mRNA of human pancreatic cancer,and to provide the experimental basis for the treatment of human pancreatic cancer with multi-epitope DC vaccine.Methods DCs were isolated and cultured from peripheral blood mononuclear cells (PBMCs) of 6 patients with pancreatic cancer.Human pancreatic cancer cell line MiaPaCa-2 was routinely cultured,after being transcripted and amplified by RT-PCR,MUC1 and survivin mRNA were co-transfected or individually transfected into DCs by electroporation,and they were named as DC-MUC1,DC-survivin,DC-MUC1 + survivin.The expression of MUC1 and survivin mRNA in DCs were detected by real-time PCR.The survival rate of transfected DCs were determined by MTT method.The lymphocyte proliferation ability was evaluated by mixed cell culture method.The Th1 cytokine releasing of antigen-specific CTLs were measured by ELISA assay.Results Mature DCs were obtained,the positive expression rates of surface markers CD40,HLA-DR,CD83 and CD86 were 34.31％,50.21％,89.17％ and 73.62％,respectively.The expression amount of MUC1 mRNA of DC-MUC1 was 36.24 ± 5.17,and the expression amount of survivin mRNA of DC-survivin was 34.53 ± 4.02,while the expression amounts of MUC1,survivin mRNA of DC-MUC1 + surviving were 31.79 ±4.26 and 14.67 ± 2.96,which were significantly lower than that in individual transfection group (P ＜ 0.05).The survival rate of DC-MUC1 + surviving was decreased in a time dependent manner,which was significantly lower than that in individual transfection group (about 50.21％ vs 80％ at 24 h,P ＜0.05).When DC/T cells ratio was 1∶ 10,1∶ 20,the autologous T cell proliferation index of MUC1 and survivin mRNA in co-transfection DC group was significantly higher than that in individual transfection group (P ＜ 0.05) ;when DC/T cells ratio was 1∶ 40,1∶ 80,the difference of proliferation index was not statistically significant.When DC/T cells ratio was 1∶ 10,after 14 d culture,the expressions of IL-2 in DC-MUC1,DC-survivin,DC-MUC1 + surviving were (892.73 ± 32.9),(713.62 ± 56.37),(1884.37 ± 95.21) pg/ml,and the expressions of granzyme B were (501.62 ± 12.30),(203.84 ± 12.55),(1193.15 ± 86.04) pg/ml ; and the expressions of IFN-γ were (981.50 ± 47.82),(696.05 ± 41.66),(2237.94 ± 189.55) pg/mL.The corresponding values in DC-MUC1 + surviving group were significantly higher than those in individual transfection group (P ＜ 0.05) ; while the difference of IL-10 was not statistically significant.Conclusions DCs co-transfected with MUC1 and survivin mRNA have a stronger ability to stimulate specific CTL in vitro than individual antigen loaded DCs.

Objective To analyze the variation of intestinal microflora in patients with colorectal cancer by SYBR GreenⅠreal-time fluorescence quantitative PCR and reveal the role and significance of intestinal microflora in the colorectal cancer-associated molecular pathogenesis.Methods A set of 16S rRNA gene group of species-specific primers for Bifidobacterium spp.,Lactobacillus group,Escherichia coli,and ddl gene-targeted species-specific primers for Enterococcus faecalis and feces Enterococcus were designed.Patients with colorectal cancer(colorectal cancer group,n=30) and healthy volunteers(normal control group,n=30) were included and whose feces were collected to extract bacterial genome DNA.SYBR GreenⅠ real-time fluorescence quantitative PCR was used to analyze the five mentioned bacterial amounts.Results Level of Bifidobacterium spp.(4.52?0.49) and Lactobacillus group(5.46?0.12) in colorectal cancer group were significantly lower than those(9.25?0.83 and 7.45?0.37) of normal control group(P

Objective To analyze the results of survival and local regional control of early-stage breast cancer patients treated with breast-conserving surgery and whole breast radiation therapy, and to explore the factors influencing local control. Methods From October 1995 to September 2005,335 patients with early-stage breast cancer were treated with breast conservative therapy, including 25 with post-operative radiotherapy alone( group A), 194 with sequential chemo-radiotherapy( group B) ,80 with concurrent chemoradiotherapy( group C), and 36 with chemo-radio-chemotherapy (group D). Axillary dissection was performed in 312 patients and sentinel node biopsy in 2. Adjuvant chemotherapy was given to 310 patients. Radiation of 50 Gy in 25 fractions was delivered to the whole breast in 256 patients,and to the breast and regional nodes in 79. Another 10 Gy in 5 fractions was boosted to the tumor bed. The proportion of patients with surgery-radiation interval of less than 4 weeks,4-8 weeks,8-20 weeks and over 20 weeks was 16.4%, 23.6% ,37.3% and 22.7% ,respectively. Concurrent chemo-radiation and" sandwich" modality were delivered in 80 and 36 patients,respectively. Results The median follow-up was 48(25.3-146.7) months. The 5-year local-regional control and ipsilateral breast control rates were 94.5% and 95.6%, respectively. The 5-year disease-free survival,metastasis-free survival and overall survival rates were 88.6% ,93.2% and 98.8% ,respectively. Lymph-vascular invasion and neural invasion were significant factors influencing local control in univariate analysis. No significant differences were found in local control rates among different surgery-radiation intervals or different sequencing of radiotherapy and chemotherapy. Multivariate analysis showed that lymph-vascular invasion and reexcision for positive or unknown margin were independent prognostic factors influencing local control. In group A + B, C and D, the frequency of grade Ⅲ skin toxicity was4.5%.80.0%.and 77.0%,respectively(χ2=226.00,P=0.000).Conclusiom Breast conservative therapy for early-stage breast eancer results in good local-regional control and overall survival.Lymph-vascular invasion and reexcision are independent prognostic factors for local control.Surgery-radiation interval and sequencing of radiotherapy and chemotherapy have no impact on local contr01.Grade Ⅲ skin toxicity of the concurTent radio.chemotherapy and the chemo.radio.chemotherapy group is significantly higher than that of the sequential chemotherapy-radiotherapy plus radiotherapy alone group.
