The diagnosis and treatment of prostate cancer are being improved due to the popularized screening of prostate specific antigen. Advanced prostate cancer, in spite of its response to androgen deprivation therapy, may finally develop into castration-resistant prostate cancer (CRPC) and shorten the overall survival of the patients. Many efforts have been made by worldwide researchers for new approaches to the management of CRPC, including new hormonal therapy, cytotoxic chemotherapy, immunotherapy, and bone metastasis-targeted therapy. This paper reviews the emerging agents undergoing clinical evaluation and drugs that have received approval for the treatment of CRPC in order to provide doctors and patients with more treatment options for CRPC and improve the overall survival rate and quality of life of the patients.

Thirty SHRs were obtained randomly to hypertension, model group, captopril group and Qingre jiangya capsule group. Ten Wistar rats were used as control group. The hippocampus tissue was removed to explore the damage of spontaneously hypertensive rats (SHR) and the protective effect of Qingre jiangya capsule after continuously administered for 14 days. And then the data were processed by principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The research results revealed captopril group was significantly different from the other three groups. The classification of other three groups is also very clear after captopril group removed. This suggested that Qingre jiangya capsule could improve the overall metabolism compared with captopril. Four metabolites were identified: dimethylglycine, glycerophosphocholine, aldosterone and noradrenaline. Hypertension hippocampus damage may mainly be expressed in tyrosine metabolism, aldosterone-regulated sodium, vascular smooth muscle contraction reabsorption, and Qingre jiangya capsule could reverse the hippocampus tissue damage of SHR.

AIM: To investigate the expression of EMMPRIN, MMP1, MMP9 and TIMP2 in retinoblastoma (RB) and normal retinal tissues and their clinicopathological significance and interrelationship.METHODS: Envision immunohistochemistry stainings of EMMPRIN, MMP1, MMP9 and TIMP2 were performed in 30 enucleated eyeballs with retinoblastoma and 15 specimens of normal retina tissue, which had been routinely imbedded with paraffin.RESULTS: Positive rate of EMMPRIN, MMP1, MMP9 expression was higher in RB tissue than in normal control (P<0.01), while TIMP2 expression was lower in RB than in normal retinal tissue (P<0.01). Samples from RB cases of clinical stage Ⅰ, differentiated type, and life span≥2 years had lower positive rate in expression of EMMPRIN, MMP1, MMP9 than those from RB cases of clinical stage Ⅲ, undifferentiated type, and life span<2 years (P<0.05 or P<0.01), while samples from RB cases of differentiated type, optic nerve unaffected, and life span≥2 years had markedly higher positive rate in expression of TIMP2 than those from RB cases of undifferentiated type, optic nerve involved and life span<2 years (P<0.05 or P<0.01). In RB tissues, EMMPRIN, MMP1, MMP9 expressions were highly consistent (P<0.05), whereas TIMP2 expression is highly inconsistent with EMMPRIN, MMP1, MMP9 expression levels (P<0.05).CONCLUSION: The expression level of EMMPRIN, MMP1, MMP9 and TIMP2 may be an important marker of RB progression, invasion and prognosis. There exist internally mutual regulation relations among them.

Abstract: Objective To investigate the diagnostic efficacy of rifampin-resistant real-time fluorescent quantitative nucleic acid amplification detection technology (GeneXpert MTB/RIF) in bronchoalveolar lavage fluid (BALF) combined with peripheral blood tuberculosis infection T cell spot test (T-SPOT) and tuberculosis antibody (TB-Ab) in smear-negative pulmonary tuberculosis. Methods The clinical data of 114 cases of clinically diagnosed smear-negative pulmonary tuberculosis, 80 cases of non-tuberculous pulmonary diseases and 22 cases of smear-positive pulmonary tuberculosis in our hospital from January 2019 to January 2021 were retrospectively analyzed. The detection results of peripheral blood T-SPOT, TB-Ab and BALF GeneXpert in the three groups were analyzed. The sensitivity, specificity, negative predictive value, positive predictive value, false negative rate, false positive rate and Youden index of the three detection methods were compared. The differences in the positive detection rate of smear-negative pulmonary tuberculosis between the separate detection and the combined detection of the three methods were compared. The receiver operating characteristic curve (ROC) was performed to calculate the area under the curve (AUC). Results The sensitivity of BALF GeneXpert and peripheral blood T-SPOT and TB-Ab was 66.91%, 80.88% and 90.44%, respectively. The specificity was 98.75%, 73.75% and 41.25%, respectively; the diagnostic coincidence rates were 78.70%, 78.24% and 72.22%, respectively, which were higher than 70.00%. In the smear-negative pulmonary tuberculosis group, the positive detection rates of these three methods in the smear-negative pulmonary tuberculosis group were 63.15%, 79.82% and 90.35%, respectively, and the differences were statistically significant compared with those in the non-tuberculosis pulmonary disease group (all P<0.01). The positive detection rate of the three combined methods in the smear-negative pulmonary tuberculosis group was 96.49 %, which was significantly higher than that of TB-GeneXpert method and T-SPOT, and the differences were statistically significant (χ2=37.283, P<0.01; χ2=13.612, P<0.01); the Youden index of combined detection was significantly higher than that of single detection, and the AUC of combined detection was 0.977, which was significantly higher than that of single detection. Conclusion BALF GeneXpert combined with peripheral blood T-SPOT and TB-Ab can significantly improve the diagnostic rate of bacterial-negative pulmonary tuberculosis, providing a strong basis for guiding clinical treatment.

OBJECTIVE:To provide reference for rational use of antibiotics to treat Pseudomonas aeruginosa (PA) infection in the clinic. METHODS:Resistant rate of PA in our hospital during 2011-2015 were analyzed retrospectively. Antibiotics use densi-ty(AUD)of 10 commonly used antibiotics were analyzed statistically,and the correlation of resistant rate with AUD was investi-gated by Spearman correlation analysis. RESULTS:One thousaud and eleven strains of PA were isolated in our hospital during 2011-2014,detection rate of PA always occupied the top 5 place. Top 3 antibiotics in the list of AUD were levofloxacin,ceftazi-dime,cefoperazone sodium and tazobactam sodium. AUD of piperacillin sodium and tazobactam sodium,levofloxacin,ciprofloxa-cin and meropenem were positively correlated with resistant rate of PA(r were 1.000,0.900,1.000,1.000,P<0.05). AUD of ce-foperazone sodium and tazobactam sodium were negatively correlated with resistant rate of PA(r=-0.900,P<0.05). AUD of imi-penem and cilastatin sodium,ceftazidime,gentamicin,aztreonam and amikacin had no correlation with resistant rate of PA(P>0.05). CONCLUSIONS:There is correlation between AUD of antibiotics and resistant rate of PA. It is of important significance to detect resistant rate of PA and the use of antibiotics regularly. Antibiotics should be selected cautiously in accordance with bacterial monitoring data,results of drug sensitivity tests,the amount and resistant rate of antibiotics,etc,in order to reduce resistant PA.
