OBJECTIVETo investigate the correlation of the deleted azoospermia (DAZ) gene copy related to gr/gr and b2/b3 deletions in the AZFc region with male spermatogenic impairment.

METHODSThis study included 121 infertile men with different de- grees of spermatogenic impairment and 95 healthy donors from the sperm bank. Using PCR, PCR-RFLP, and Y chromosome specific sequence tagged sites (STS) , we analyzed the association of DAZ gene copy deletions related to gr/gr and b2/b3 deletions in the AZFc region with spermatogenic impairment.

RESULTSThere were 15 cases of gr/gr deletion (12. 40% ) and 6 cases of b2/b3 deletion (4.96%) in the infertility group as compared with 13 cases of gr/gr deletion (13.68%) and 1 case of b2/b3 deletion (1.05%) in the control. Analysis of the DAZ-specific single nucleotide variant (SNV) loci revealed 11 gr/gr-DAZI/DAZ2 deletions (9.09%), 4 gr/gr-DAZ3/DAZ4 deletions (3.31%), and 6 b2/b3-DAZ1/DAZ2 deletions (4.96%) in the infertile men in comparison with 3 gr/ gr-DAZ1/DAZ2 deletions (3.16%), 10 gr/gr-DAZ3/DAZ4 deletions (10.53%), and 1 b2/b3- DAZ3/DAZ4 deletion (1.05%) in the control.

CONCLUSIONPartial deletions of gr/gr and b2/b3 exist in both healthy men and male patients with different degrees of spermatogenic impairment and cannot be considered as a risk factor for spermatogenesis impairment. However, deletions of different DAZ duplicons in gr/gr and b2/b3 deletions have different effects on spermatogenesis. DAZ1/DAZ2 instead of DAZ3/DAZ4 deletions might be associated with spermatogenesis impairment.

Prostate cancer (PCa) is one of the most common malignant tumors as well as a frequent cause of cancer-related mortality in men worldwide. The test of serum markers has dramatically improved the early diagnosis of PCa, but its underlying molecular mechanisms are not yet completely identified. Long noncoding RNA (IncRNA) is emerging as a new player in the PCa paradigm demonstrating its potential roles in both oncogenic and tumor suppressive pathways. LncRNA is frequently aberrantly expressed in the majority of PCa cases. This review highlights recent findings of the aberrant expression of lncRNA in PCa and discusses its novel roles in the diagnosis, prediction, prognosis, metastasis, and potential clinical treatment of PCa.

OBJECTIVETo investigate the factors influencing the prognosis of penis-sparing surgery (PSS) for early-stage penile cancer.

METHODSWe retrospectively studied the clinical data about 45 cases of early-stage penile cancer treated by PSS from January 2007 to December 2014. We calculated the rate of local recurrence-free survival by the Kaplan-Meier method, and conducted univariate and multivariate COX regression analyses on the relevant factors including the patient's age, marital status, tumor location, tumor size, postoperative sexual life, histological grade, and TNM stage.

RESULTSOne-year and three-year local recurrence-free survival rates were 95.5% and 52.2%, respectively. Multivariate analysis demonstrated that the histological grade (P = 0.039) and postoperative sexual life (P = 0.049) were independent factors for the prognosis of PSS. Logistic regression showed the patients age to be significantly associated with histological grade (P = 0.014).

CONCLUSIONHistological grade and postoperative sexual life are important independent prognostic factors of PSS for early-stage penile cancer, and the patients age is associated with the prognosis of PSS through its influence on the tumor grade.

Stroke is responsible for increasingly high rates of mortality and disability worldwide. Approximately two million people suffer from stroke for the first time in China each year. The high incidence (50%) of post-stroke disability brings a heavy burden to patients and their caregivers. Acupuncture has been widely used in the communities for post-stroke rehabilitation in China. The objective of this trial is to apply our acupuncture research achievement to treatment and evaluation of post-stroke hemiplegic patients in community.

Objective To construct the eukaryotic expression plasmids of short hairpin RNA (shRNA) specific for mouse Bcl-2-assoeiated athanogene 1 (BAG-1) and to observe their inhibitory effects on the expression of BAG-1 gene in mouse melanoma B16FI0 ceils. Methods Plasmids named pRNAT-U6.1/Neo-BAG-1, were designed and constructed to target the mouse BAG-1 mRNA coding region. LipofectaminTM 2000 was used to transfect plasmids into BI6F10 cells. Negative plasmid-transfected and tmtransfected B16F10 cells served as negative and blank controls respectively. Forty-eight hours following transfection, G418 was used to select the resistant cells. The mRNA and protein expression of BAG-1 gene was measured by reverse transcription-PCR and Western blot respectively about 1 month after the transfection. Results The eukaryotic expression plasmids, pRNAT-U6.1/Neo-BAG-1, were constructed, and verified by restriction enzyme digestion and DNA sequencing. The transfection rate in B16F10 cells was 20% -30%. Compared with the blank control, the mRNA and protein expression of BAG-1 in BI6FI0 cells was significantly inhibited by BAG-1 shRNA (both P<0.05), and the inhibition rates were (77±4)% and (62 ±2)%, respectively. Conclusions These results indicate that the eukaryotic expression vectors containing shRNA against BAG-1 gene, pRNAT-U6.1/Neo-BAG-1, are successfully constructed, and can significantly inhibit the expression of BAG-1 gene in mouse melanoma B16F10 cells.

Objective To investigate the pharmaeokinetics of levofloxacin in rat's pancreatic tissue. Methods Pancreatic tissue and blood were sampled in vivo by microdialysis simultaneously. The concentrations of levofloxacin in beth blood and tissues were measured by high performance liquid chromatography. All date were analyzed by WinNonlin software. Results The maximum concentration of free levofloxacin in blood and pancreatic tissue were (65.23 ± 12.9) μg/ml at 10min and (30.56±3.22) μg/ml at 20 min, respectively, then beth continuously decreased. Concentration of free levofloxacin in pancreatic tissue was higher than that in blood from 20min to 100min, then returned to similar level. The area under the concentration curve(AUC)of unbound levofloxacin was(2465.11±258.56)min·μg~(-1)·ml~(-1) in pancreas,and (2914.38±205.73)min·μg~(-1)·ml~(-1) in blood.Conclusions Microdialysis with reversed phase high performance liquid chromatography established in this essay could be used to determine the pharmacokinetics of levofloxacin objectively. High concentration of levofloxacin in pancreatic tissue and blood was observed.

Objective: To analyze clinical characteristics and risk factors in patients with acute myocardial infarction (AMI) complicated with cardiac rupture (CR) and to explore the prevention and treatment strategy in clinical practice. Methods: A case control study was conducted in 2 groups: CR group, the patients with coronary angiography conifrmed AMI with CR,n=44 and Control group, the patients with simultaneous STEAMI and by 1:3 pair-matched ratio,n=132. Clinical information was compared between 2 groups and the relevant risk factors for predicting CR were studied by Logistic regression analysis. Results: Compared with Control group, CR group had the lower ratio of β-receptor blocker application (22.7% vs 81.4%),P<0.05. Univariate regression analysis indicated that lower body mass index, incipient MI, anterior MI, no-reperfusion therapy, delayed reperfusion therapy, lower blood pressure at admission, post-infarction angina, ventricular aneurysm, higher Gensini score, high blood levels of cretinine and BNP, low ejection fraction were the risk factors for CR occurrence in STEAMI patients, allP<0.05. Multivariate regression analysis presented that incipient MI (P<0.049, OR=7.462), post-infarction angina (P<0.000, OR=8.591), ventricular aneurysm (P<0.005, OR=4.617) and higher Gensini score (P<0.001, OR=2.788) were risk factors for CR occurrence in STEAMI patients. Conclusion: Incipient MI, post-infarction angina, ventricular aneurysm and higher Gensini score are the risk factors for CR occurrence in STEAMI patients.

OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.
