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.

Objective To investigate the relationship between anti-HCV antibody level and hepatitis C virus genotype in the patients.Methods Total of 603 anti-HCV positive serum samples were collected during 2013 to 2014 by retrospective research method.HCV RNA were detected in anti-HCV positive samples by repeat test and the genotype were detected in HCV RNA positive samples.The distribution of anti-HCV level in different hepatitis C genotype patients was analyzed and the body's response to viral antibodies and viral genotype correlation with anti-HCV concentration interquartile range was explored.Rates among genotype groups were compared using chi-square test.Results Totally 412 of 603 (68.33%) samples were anti-HCV positive by double reagent screening.174(42.3%) samples were detected as HCV RNA positive.The distributions of different anti-HCV level in different genotype patients were 1a(n =8) 1/8,1/8,4/8,2/8;1b(n =112)25.9% (29/112),17.0% (19/112),25.9% (29/112),31.3% (35/112);2a(n =14)3/14,4/14,5/14,2/14;3a(n =11)3/11,6/11,2/11,0/11;3b(n =16)4/16,11/16,1/16,0/16;6a(n =8)2/8,2/8,1/8,3/8 with anti-HCV concentration interquartile range respectively.The anti-HCV concentration distribution was different in patients with different HCV genotypes.The anti-HCV concentration distribution in patients of 1 b,2a and 6a genotypes were evently,while anti-HCV level was relatively high in 1a (13.65) and relatively low in 3b (8.77).There were differences in different genotypes of antibody concentrations (x2 =35.2,P < 0.05).Conclusions There was correlation between anti-HCV level and HCV genotype.Because there were fewer cases in some genotypes,it was necessary to investigate more samples to corfirm the above results.

Persicae Semen (PS), a traditional Chinese medicine, has been widely used for the syndrome of blood stasis in China since the Eastern Han Dynasty. In the present study, we developed an HPLC-UV fingerprint analysis method for the quality control of PS. The HPLC fingerprint was performed on Shimadzu Inertsil C18 column (4.6 mm x 250 mm, 5 microm) at 35 degrees C. The mobile phases were composed of acetonitrile and water using a gradient elution. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 210 nm. The fingerprint method was validated according to the Guidelines for Traditional Chinese Medicine Injection Fingerprint, and applied to determine 41 batches representative herbs collected from Xinjiang of China. The chromatographic peaks were characterized by UPLC-Q-TOF-MS, and nine of them were identified by comparison with the literature and/or reference standards. In order to classify and assess the samples, hierarchical clustering analysis and partial least square discriminant analysis were performed based on the common chromatographic peaks, and the samples were geographically classified into two classes, with six chemical compounds as classification markers which were significantly different between the two classes (P < 0.05).

OBJECTIVETo observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy.
METHODSTotally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared.
RESULTSDifferent treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both).
CONCLUSIONSBoth constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.

AIM:To investigate the effects of 1.8mm coaxial micro incision phacoemulsification on corneal endothelial injury and postoperative visual acuity.METHODS: Totally 145 eyes in 120 patients underwent phacoemulsification from July 2013 to July 2015 were randomly divided into observation group 60 cases (73 eyes) and control group 60 cases (72 eyes).The observation group 60 cases were given 1.8mm coaxial micro incision cataract phacoemulsification operation,while the control group were given traditional 3.2mm coaxial micro incision cataract surgery.The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),corneal thickness of incision area,incision width,incision length,macular retinal thickness,surgically induced astigmatism,corneal endothelial cell counts and complications of the two groups were compared.RESULTS: The UCVA and BCVA on 1wk after surgery of the observation group were significantly higher than the control group (t=3.604,7.109;P<0.05);the width of incision on 1wk and 1mo after surgery of the observation group were significantly less than the control group (t=205.3,225.2;P<0.05).The length of incision in observation group was significantly greater than the control group (t=3.926,5.009;P<0.05).Macular retinal thickness 1wk after surgery of the observation group was significantly less than the control group (t=2.817,P<0.05).The surgically induced astigmatism was significantly less than the control group (t=19.43,22.16;P<0.01);the difference of corneal edema between the two groups was not significant (8.22% vs 11.11%) (x2=0.348,P>0.05).CONCLUSION: The 1.8mm micro incision phacoemulsification is helpful to improve the visual acuity of patients with cataract phacoemulsification,which may be related to the reduction of corneal cell injury,enhancement of corneal closure and decrease post-operation corneal original astigmatism.
