This study compared the diagnostic efficacy of transrectal ultrasound(TRUS)-guided prostate biopsy(TRBx)and transperineal prostate biopsy(TPBx)in patients with suspected prostate cancer(PCa).We enrolled 2962 men who underwent transrectal(n=1216)or transperineal(n=1746)systematic 12-core prostate *** data including age,prostate-specific antigen(PSA)level,and prostate volume(PV)were *** minimize confounding,we performed propensity score-matching analysis?We measured and compared PCa detection rates between TRBx and TPBx,which were stratified by clinical characteristics and gleason *** effects of clinical characteristics on PCa detection rate were assessed by logistic *** all patients,TPBx detected a higher proportion of clinically significant PCa(Pgistic regression analyses illustrated that PV had a smaller impact on PCa detection rate of TPBx compared with *** score-matching analysis showed that the detection rates in TRBx were higher than those in TPBx for patients aged≥80 years(80.4%vs 56.5%,P=0.004)and with PSA level 20.1-100.0 ng ml^-1(80.8%vs 69.1%,P=0.040).In conclusion,TPBx was associated with a higher detection rate of clinically significant PCa than TRBx was;however,because of the high detection rate at certain ages and PSA levels,biopsy approaches should be optimized according to patents'clinical characteristics.

引用

International Journal of Ophthalmology(English edition) 2019年第6期12卷 898-903页

作者： Jia-Qian Jiang Cui Li Cong-Xian Cui Yu-Na Ma gui-Qiu Zhao Xu-Dong Peng qiang Xu Qian Wang guo-qiang Zhu chen-Yu Li Department of Ophthalmology the Affiliated Hospital of Qingdao University

AIM: To investigate the inflammatory amplification effect of high-mobility group box 1(HMgB1) in Aspergillus fumigatus(A. fumigatus) keratitis and the relationship between lectin-like oxidized low-density lipoprotein receptor 1(LOX-1) and HMgB1 in keratitis immune ***: Phosphate buffer saline(PBS), and Boxb were injected into BALB/c mice subconjunctivally before the corneas were infected with A. fumigatus. RAW264.7 macrophages and neutrophils were pretreated with PBS and Boxb to determine the HMgB1 inflammatory amplification effects. Abdominal cavity extracted macrophages were pretreated with Boxb and Poly(I)(a LOX-1 inhibitor) before A. fumigatus hyphae stimulation to prove the the relationship between the two molecules. LOX-1, interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), macrophage inflammatory protein-2(MIP-2) and IL-10 were assessed by polymerase chain reaction and Western ***: Pretreatment with Boxb exacerbated corneal inflammation. In macrophages and neutrophils, A. fumigatus induced LOX-1, IL-1β, TNF-α and MIP-2 expression in Boxb group was higher than those in PBS group. Poly(I) treatments before infection alleviated the proinflammatory effects of Boxb in abdominal cavity extracted macrophages. Pretreatment with Boxb did not influence Dectin-1 mRNA levels in macrophages and ***: In fungal keratitis, HMgB1 is a proinflammatory factor in the first line of immune response. HMgB1 mainly stimulates neutrophils and macrophages to produce inflammatory cytokines and chemokines during the immune response. LOX-1 participates in HMgB1 induced inflammatory exacerbation in A. fumigatus keratitis.

Chinese Medical Journal 2008年第20期121卷 2065-2069页

作者： CAI Chang-jie chen Hu-an LU Min-qiang.chen gui-hua Department of Liver Transplantation Third Affiliated Hospital of Sun Yat-sen University Guangzhou Guangdong 510630 China

Background Serum sodium predicts prognosis in chronic severe hepatitis B and may improve the prognostic accuracy of the model for end-stage liver disease （MELD） score, but the available information is limited. The present study was undertaken to study the clinical use of the serum sodium incorporated MELD （MELD-Na） and assess its validity by the concordance （c）-statistics in predicting the prognosis of the patient with chronic severe hepatitis B.Methods A total of 426 adult patients with a diagnosis of chronic severe hepatitis B between January 1, 2007, and December 31, 2007 at a single center were studied. The scores of serum sodium, MELD, MELD-Na, and ΔMELD-Na （ΔMELD-Na=MELD-Na at 14 days after medical treatment -MELD-Na score on admission） of the patients with chronic severe hepatitis B were calculated. The 3-month mortality in the patients was measured, and the validity of the models was determined by means of the concordance （c） statistics.Results The average MELD, MELD-Na scores of survival group were 25.70±5.08 and 26.60±6.90, and those of dead group were 35.60±6.78 and 42.80±9.57 on admission. There was a significant difference in MELD and MELD-Na between the survival and dead groups （P 〈0.01）. The average △MELD-Na score of the survival group was -0.97±3.51, and that of the dead group was 3.45±2.38 at 2 weeks after the treatment. There was a significant difference in △MELD-Na between the survival and dead groups （P 〈0.01）. The areas under the receiver-operating characteristic curves of Na, MELD and MELD-Na for the occurrence of death in 3 months were 0.742, 0.875 and 0.922. The 3-month mortality of the MELD-Na scores group 〈25, 25-30, 31-34, 35-40 and 〉40 were 2.0%, 5.4%, 35.4%, 53.8 % and 86.9%, respectively. There was a significant difference in the 3-month mortality between the five groups （P 〈0.05）. The 3-month mortality of the △MELD-Na〉0 group was 65.9%, and that of the △MELD-Na ≤0 group was 15.8%; there was a significant difference in the 3-month m

A novel biosorbent: characterization of the spent mushroom compost and its application for removal of heavy metals

引用

Journal of Environmental Sciences 2005年第5期17卷 756-760页

作者： chen gui-qiu ZENg guang-ming TU Xiang HUANg guo-he chen Yao-ning Department of Environmental Science and Engineering Hunan University Changsha 410082 China

The spent mushroom compost of Lentinus edodes was used as a biosorbent for adsorbing cadmium, lead and chromium from solutions under batch conditions for the first time. Titration of the biomass revealed that it contained at least three types of functional groups. The Fourier transform infrared spectrometry showed that the carboxyl, phosphoryl, phenolic groups were the main groups. The simulated values of pK, and molar quantity were 5.00 and 0.44 mmol/g, 7.32 and 1.38 mmol/g, 10.45 and 1.44 mmol/g, respectively. The biosorption ability increased with pH in acid condition. When 10 mg/L biomass dosage was added in, there was no significant increment of metal uptake. The maximum uptake estimated with the Langmiur isotherm model were 833.33 mg/g for Cd（ Ⅱ ）, 1000.00 mg/g for Pb（ Ⅱ ） and 44.44 mg/g for Cr（ Ⅲ ）, respectively. All the results showed that vast potential sorption capacity was existed in the biomass for adsorbing these three kinds of metals studied.
