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.

OBJECTIVETo observe the characteristics of sperm single-stranded DNA breaks (SSB) and double-stranded DNA breaks (DSB) in infertile men, explore the association of DSB with male infertility, and provide a new observation index and idea for the diagnosis and treatment of the disease.

METHODSThis study involved 60 infertile men (infertility group) and 30 normal healthy males with infertile wives (control group). We comparatively analyzed the seminal parameters of the two groups, determined sperm concentration and viability using the computer aided sperm analysis system, measured the sperm survival rate by hypoosmotic swelling (HOS) test, examined sperm morphology by Diff-Quick staining, and detected sperm DNA damage by two-tail comet assay.

RESULTSNine two-tail comet models were established for detecting sperm DNA integrity. Comparisons between the fertility and control groups showed that the sperm DNA fragmentation index (DFI) was (33.8 ± 13.1) vs (16.3 ± 7.9)% (P < 0.01), the SSB-DFI was (19.2 ± 11.4) vs (14.9 ± 7.6)% (P > 0.05), the SSB-DFI/DFI was (56.8 ± 32.4) vs (91.4 ± 27.8)% (P < 0.01), the DSB-DFI was (23.9 +13.4) vs (6.1 ± 2.7)% (P < 0.01), and the DSB-DFI/DFI was (70.8 ± 19.5) vs (37.4 ± 11.3)% (P < 0.01). The optimal cut-off value of DSB-DFI/DFI in the diagnosis of male infertility was 39.5%, with the AUG, sensitivity, and specificity of 0.969, 98.3%, and 90%; that of DSB-DFI was 15.85%, with the AUC, sensitivity, and specificity of 0.912, 86.7%, and 80%; and that of DFI was 18.65%; with the AUC, sensitivity, and specificity of 0.861, 90%, 70%, respectively. In the infertile men, neither SSB-DFI nor SSB-DFI/DFI exhibited any correlation with semen parameters (P > 0.05); DFI was correlated negatively with the percentage of progressively motile sperm, sperm survival rate, and the percentage of morphologically normal sperm (P < 0.05 or P < 0.01), but not correlated with sperm concentration (P > 0.05); both DSB-DFI and DSB-DFI/DFI showed a negative correlation with sperm concentration, sperm survival rate, and the percentages of progressively motile sperm and morphologically normal sperm (P < 0.05 or P < 0.01).

CONCLUSIONDouble-stranded, rather than single-stranded DNA breaks, may be a factor inducing male infertility. The type of sperm DNA strand damage is of much reference value for the assessment of male fertility.

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.

The tissue-specific and MeJA-induced transcriptional levels of BcUGT3 and BcUGT6 in Bupleurum chinense were analyzed in the present study. The transcriptional levels of BcUGT3 in root, leaf, flower and fruit were similar and they all were higher than those in stem. The transcriptional level of BcUGT6 was the highest in leaf and the lowest in flower among in all tested tissues. With non-treated adventitious roots as control, BcUGT6's transcriptional levels were elevated to nearly 2 folds for 2 h, 8 h, 24 h, 2 d and 4 d in MeJA-treated adventitious roots of B. chinense. It showed that the transcriptional level of BcUGT6 was slightly affected by MeJA. While, BcUGT3's transcriptional levels were gradually elevated, and till 4 d after MeJA treatment, the expression level was about 7 folds than that of non-treated control. Using pET-28a (+), the expressions of two genes was investigated. Induced by IPTG, the target proteins were expressed in E. coli and then purified. All the results obtained in the present study will be helpful for follow-up bio-function analysis of BcUGT3 and BcUGT6.

OBJECTIVETo explore rest, cold compress and elevate (RICE) with rest, compress and elevate (RCE) without cold for the treatment of acute ankle sprain, in order to clear mid-term clinical effects.

METHODSEighty-nine patients with acute ankle sprains were collected from January 2013 to March 2014,including 30 males and 59 females aged from 18 to 60 years old with an average of 36 years old; the time from injury to hospital ranged from 3 to 24 h with an average of 9 h. All patients were divided into two groups according to visiting sequence. There were 45 patients in RICE group, and 45 patients in RCE groups. The main therapeutic effect index was evaluated by Karlsson scoring, and secondary therapeutic effect index was pain and satisfactory VAS scores. Safety index evaluated by adverse event.

RESULTSOn the 2nd weeks after injury, Karlsson score in RICE group was 44.66 ± 11.58, and 46.67 ± 8.52 in RCE group, while there was no statistical significance between two groups in Karlsson scores (P > 0.05). Karlsson score of two groups after treatment were higher than before treatment. There was no significantly meaning in pain and satisfactory VAS scores between two groups (P > 0.05). No adverse reaction were occurred between two groups.

CONCLUSIONCold compress did not receive much more final gains, and no evidence showed cold compress could affect recovery of joint function.
