Objective To synthetically evaluate medical treatment outcomes of two operative methods on benign prostatic hyperplasia (BPH),and to provide evidence for therapeutic regimen selection.Methods Prospective cohort study was applied.BPH patients were treated by two operative methods randomly,follow-up observations were carried out at 3 months,6 months,and 48 months after the treatment.IPSS and BPHQLS were adopted to evaluate prostate and quality of life of patients at different time.The weight coefficients of IPSS score,quality of life score and general hospitalization expense in the comprehensive evaluation were defined by the Delphi Method.Results The synthetic score of both groups showed ascending trend,comprehend evaluation of scores got after treatment for 3 months (OP group was 7.6±0.7,TURP group was 7.4±0.8),6 months(OP group was 6.9 ± 0.9,TURP group was 6.9 ± 1.1) showed no significant differences between two groups(P＞0.05),curative effect of OP group was better than TURP group at 48 moths(OP group was 8.3±0.9 score,TURP group was 7.6± 0.8 score) (P＜0.05).Conclusions The curative effect of OP group was better than TURP group at 48 months.

Objective To study the changes and clinical value of platelet(PLT)parameters and coagulation indicators in children with severe pneumonia.Methods 97 children were divided into severe pneumonia groupⅠand severe pneumonia groupⅡ according to whether children were associated with other diseases besides severe pneumonia,and 30 healthy chil-dren were in control group.The levels of PLT count,mean platelet volume(MPV),prothrombin time(PT),activated par-tial thromboplastin time(APTT),fibrinogen(FIB),antithrombin-Ⅲ(AT-Ⅲ),and D-dimer(DD)among three groups were compared.Results The differences of PLT,MPV,DD and AT-Ⅲ activities were all significant among three groups (all P < 0.05).PLT,MPV and DD levels in group Ⅰ were all significantly higher than those of control group ([454.00±157.00]×109/L vs [300.00±63.00]×109/L ;[9.66±1.24]fL vs [8.90±0.37]fL;[0.47±0.37] mg/L vs [0.27±0.06]mg/L,respectively);AT-Ⅲ activity in groupⅠ was lower than control group([79.91 ± 20.34]% vs[107.03±8.11]%)(both P <0.05).AT-Ⅲ activity and PLT level in group Ⅱwas (66.11±11.12)%and (279.00±185.00)×109/L respectively,which were both significantly lower than group Ⅰ,MPV and DD level was (10.37± 1.51)fL and (0.70±0.46)mg/L respectively,which were both higher than groupⅠ (both P <0.05).Conclusion There is obvious coagulation dysfunction in children with severe pneumonia.The changes in PLT,MPV,AT-Ⅲ and DD levels are associated with the severity of pneumonia.

Objective To study the impact of laparoscopic radical resection and open radical resection on immune function in patients with colon cancer. Methods 110 cases received complete mesocolic excision surgery of the right colon cancer patients, according to the different surgical methods divided into observation group and control group, the observation group adopted laparoscopic surgery while the control group treated with open surgery, then compared the inflammatory stress response and related immunology index changes before and after operation. Results After op-eration, inflammatory stress indicators such as MCP-1, HMGB-1, Glucagon, BG in observation group were signifi-cantly better than that in control group. After operation, WBC, CRP, IL-6 index in the two groups were significantly improved. CRP, IL-6, CD4+, CD8+, NK cell index in observation group was significantly better than that in control group. There were significant differences between the two groups, < 0.05. Conclusion Laparoscopic CME surgery can help to relieve inflammatory stress response, and the immune function is less affected, it is worthy of promoting clinical application.

Objective To analyze the functional alteration of natural killer (NK) cells from patients with macrophage activation syndrome (MAS) in active phase and after treatment.Methods Peripheral blood samples were collected from 12 healthy subjects,12 patients with systemic onset juvenile rheumatoid arthritis (SoJIA) but without an episode of MAS and 12 patients with MAS.Flow cytometry analysis was performed to detect NK cells and their expression of perforin,granzyme B,interferon (IFN)-γand tumour necrosis factor (TNF)-α.The cytotoxicity of NK cells to K562 cell was also analyzed.All of the patients with MAS were diagnozed by clinical features and the pathologic examination of hemophagocytosis in bone marrow.The function of NK cells were analyzed before any treatment and on the fifth day as well as in third month after treatment with glucocorticoid,intravenous immunoglobulin and/or cyclosporin A.Results Compared with healthy subjects and patients with SoJIA,patients with MAS had lower NK cell counts,reduced cytotoxicity and decreased expression of perforin and granzyme B before or on the fifth day after treatment (P＜0.05).However,increased production of IFN-γ and TNF-α by NK cells were observed (P＜ 0.05).In the third month after treatment,the cytotoxicity of NK cells and the expression of perforin and granzyme B in patients with MAS were lower than those in healthy subjects and patients with SoJIA (P＜ 0.05),but no statistically significant differences with NK cell counts and production of IFN-γand TNF-α were observed beween the patients with MAS and healthy subjects (P＞0.05).Conclusion NK cells from patients with active MAS were characterized by reduced cytotoxicity and enhanced production of IFN-γ and TNF-α.Upon medical treatment,the number of NK cells in patients with MAS were up-regulated and their production of IFN-γand TNF-α were down-regulated.However,the cytotoxicity of NK cells and the expression of perforin and granzyme B were not affected.Reduced cytotoxicity and decreased production of perforin and granzyme B with NK cells might be the durative features for the patients with MAS.

Objective To study the change and clinical significance of coagulation and fibrinolytic function in neonatal sepsis. Methods 86 neonates inpatients in the neonatology department of our hospital were selected and divided into the ordinary infection group(30 cases)and the sepsis group(56 cases),and 30 healthy neonates were selected as the normal control group.Plasma AT-Ⅲactivity,DD level and PLT count were detected immediately after admission and the detection results were analyzed.Results Com-pared with the control group and the ordinary infection group,the AT-Ⅲ activity and the PLT count in the sepsis group were sig-nificantly decreased,while the DD level was significantly increase,the difference had statistical significance(P <0.01).The differ-ences of the three indexes had no statistical significance between the normal control group and the ordinary infection group(P >0.05);however,the AT-Ⅲ activity and the PLT count in the DIC group were significantly decreased and the DD level was signifi-cantly increased(P <0.01),the occurrence rate of abnormal three indexes was 83.33%(15/18)in the DIC group,which was signifi-cantly higher than that in the non-DIC group(χ2 =17.75,P =0.00).Conclusion The obvious dysfunction of coagulation and fibri-nolysis exists in neonatal sepsis,which is related with the severity degree of disease.The joint detection of AT-Ⅲ activity,DD level and PLT count is helpful for the early diagnosis of DIC in neonatal sepsis.

Objective To study the clinical value of serum N-terminal pro-brain natriuretic peptide (NT-ProBNP) and cardiac troponin I (cTnI) levels in children with severe pneumonia. Methods A total of 72 children with severe pneumonia in pediatric intensive care unit were divided into heart failure (HF) group and non-HF group according to the occurrence of heart failure, and 30 healthy children were selected as control group. Serum NT-ProBNP and cTnI levels were detected and analyzed. Results Compared with control group, NT-ProBNP and cTnI levels were signiifcantly higher (P<0.01) in HF and non-HF group. The levels of NT-ProBNP and cTnI in HFgroup were both signiifcantly higher (P<0.01) than that in non-HFgroup. Serum NT-ProBNP level was positively related to the level of cTnI(P=0.000) in children with severe pneumonia. The abnormal rate of cTnI in HF group was significantly higher (P=0.037) than that in non-HFgroup. The difference of the abnormal rate of NT-ProBNP between the two groups was not signiifcant (P=0.375), however, the abnormal rate of NT-ProBNP was signiifcantly higher (P=0.036) than that of cTnI in non-HF group. Conclusions There was obvious myocardial damage in children with severe pneumonia. NT-ProBNP and cTnI could be important serological markers to assist diagnosis of myocardial damage and its severity.

Abstact:Objective To investigate the clinical value of mean platelet mass(MPM)and the procalcitonin(PCT)in diagnosis of Kawasaki disease (KD).Methods A Total of 117 children with KD in the acute stage and 126 children of the control group were detected respectively and compared each other.The indexes contain MPM,PLT,MPV,PDW and PCT.Mean-while,the comparison of each index’s positive rate and the linear correlation analysis of each index were conducted.Results①The level of MPM of the KD group was significant lower than that of the control group,PLT,MPV and PCT significant higher than those (P<0.05,α=0.05).The difference of PDW between the two groups was no statistical significance (P>0.05,α=0.05).②The positive rate of the MPM was significant higher than that of the other indexes (P<0.05,α=0.05). Conclusion The detection of MPM is helpful to the diagnosis of KD and can be used as an indicator of KD clinically.

OBJECTIVETo investigate trichorhinophalangeal syndrome 1 gene (TRPS-1) expression patterns in different subtypes of breast cancer and its correlations with other genes and survival using microarray data sets.

METHODSThe transcripts of TRPS-1 and its role in survival in breast cancer were analyzed using published microarray data sets#x02014;Netherlands Cancer Institute (NKI) cohort and Wang cohort.

RESULTSTRPS-1 expression was lower in basal-like breast cancer. The mRNA levels of TRPS-1 negatively correlated with Slug (Pearson correlation coefficient=-0.1366, P=0.0189 in NKI data set and Pearson correlation coefficient=-0.1571, P=0.0078 in Wang data set), FOXC1 (Pearson correlation coefficient=-0.1211, P=0.0376 in NKI data set and Pearson correlation coefficient=-0.1709, P=0.0037 in Wang data set), and CXCL1 (Pearson correlation coefficient=-0.1197, P=0.0399 in NKI data set and Pearson correlation coefficient=-0.3436, P<0.0001 in Wang data set), but positively correlated with BRCA1 (Pearson correlation coefficient=0.1728, P=0.0029 in NKI data set and Pearson correlation coefficient=0.1805, P=0.0022 in Wang data set). Low TRPS-1 expression associated with poor overall survival (hazard ratio 1.79, 95% CI of ratio 0.9894 to 3.238, P=0.054) and relapse-free survival (hazard ratio 1.913, 95% CI of ratio 1.159 to 3.156, P<0.05). The low TRPS-1 mRNA levels predicted poor outcome in breast cancer patients by the 70-gene signature.

CONCLUSIONThe strong expression of TRPS-1 may serve as a good prognostic marker in breast cancer.

Purpose To observe white matter structure features of patients with early stage (Hoehn-Yahr 1-2 phase) Parkinson''s disease (PD) by using diffusion tensor imaging (DTI) based on the fiber bundle analysis tract-based spatial statistics (TBSS); and to explore the brain regions of PD patients in which DTI parameters are significantly correlated with unified Parkinson''s disease rating scale (UPDRS) score elevation. Materials and Methods DTI sequence was performed on 27 cases of PD and 30 cases of healthy volunteers. DTI parameters including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) were analyzed in all participants by using TBSS technique, and the parameters of two groups were compared. The correlation of clinical UPDRS score with FA value, MD and RD value in the PD group were analyzed.Results Compared with that in the control group, FA values of several brain regions in PD group decreased, while MD and RD value increased (P<0.05). AD showed no obvious change (P>0.05). UPDRS score of PD group was correlated with FA, MD and RD value (P=0.001). The brain regions that showed FA value decreased, MD and RD value increased included corpus callosum, left anterior limb of internal capsule, bilateral anterior radial crown, bilateral superior radial crown and left posterior thalamic radiation (P=0.001).Conclusion There is some changes in white matter structure of the patients with early stage Parkinson''s disease, which may due to demyelination or fiber integrity damaged.
