To evaluate changes in quality- of- life of adults with concomitant exotropia before and after surgery.
●METHODS:A retrospective cohort method was used in this research. Sixty - five patients with concomitant exotropia ( ranged from 18 - 30 years) were enrolled. Quality of life was studied with 2 different questionnaires [the Adult Strabismus - 20 ( AS - 20) and the MOS 36 -item Short - Form health survey ( SF - 36 )], which patients completed preoperatively and at 3mo postoperatively.
●RESULTS: With the AS - 20, 3mo after surgery, the mean psychosocial and visual function scores of AS- 20 improved significantly (P<0. 01). Similarly, with the SF-36, the mean score in 7 of 8 areas improved significantly ( P < 0. 01 ), including physiological function, role limitations due to physiological health, general health, vitality, social function, role limitations due to emotional problems, mental health and the overall mean score. However, with respect to bodily pain, no significant improvement was found after surgery(P>0. 05).
● CONCLUSlON: Surgical treatment of concomitant exotropia in adults gives a highly significant improvement in quality - of - life scores. We should pay more attention to the impact of strabismus on quality of life clinically to improve the outcome of the surgery.

OBJECTIVETo explore the therapeutic effects of amiodarone and metoprolol, either alone or in combination, on chronic heart failure (CHF) complicated by ventricular arrhythmia.

METHODSA total of 110 NYHA class II-III patients with CHF complicated by ventricular arrhythmia were randomly divided into amiodarone group, metoprolol group and amiodarone + metoprolol group. The therapeutic effects was evaluated at the end of the 1-year follow-up.

RESULTSAmiodarone, metoprolol and their combination produced statistically different therapeutic effects (P<0.05). Compared with amiodarone and metoprolol used alone, amiodarone combined with metoprolol resulted in significant cardiac function improvement (P<0.05) and ventricular arrhythmia control (P<0.01). During the 1-year follow-up, the readmission rate and cardiac event rate in the amiodarone + metoprolol group were significantly lower than those in amiodarone group (P<0.01) and metoprolol group (P<0.05). The adverse reaction rates in the 3 groups were similar (P>0.05).

CONCLUSIONThe combination of amiodarone and metoprolol produces better effect than amiodarone or metoprolol alone in the treatment of CHF complicated by ventricular arrhythmia.

Multilocus sequence typing (MLST) is a molecular genotyping method based on nucleotide sequencing. The procedure of this method characterizes isolates of bacterial species using the DNA sequencing of multiple housekeeping genes(usually seven). For each housekeeping gene, the different sequences present within a bacterial species are assigned as distinct alleles.For each isolate, the alleles at each of the loci define the allelic profile or sequence type (ST). MLST has the advantages of being robust (based on genetic data) and electronically portable to generate data that allow rapid and global comparisons between different laboratories. In this paper, the principle, method, data analysis, application, advantages and flaws of MLST are introduced.

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.

Objective To investigate BAALC(brain and acute leukemia cytoplasmic)gene expression in patients with de novo acute myeloid leukemia(AML)and its clinical significance. Methods BAALC expression was determined by real-time quantitative polymerase chain reaction(RQ-PCR) in 63 de novo AML patients.The association between BAALC expression and therapeutic effect was analyzed.Results The correlation coefficiencies were over 0.99 for standard curves of RQ-PCR method. BAALC expression was detected in 49(78%)AML patients.The peripheral WBC counts,hemoglobin, platelet counts and the bone mahow blast cell percentage at onset in 31 AML patients with high BAALC expression were(26.3?18.1)?10~9/L,(78.3?21.8)g/L,(76.9?64.5)?10~9/L and(61.2?22.3)% and those of 32 AML patients with low BAALC expression were(30.2?21.7)?10~9/L,(81.6?30.9)g/L, (73.9?57.2)?10~9/L,(54.3?16.3)%,respectively.No statistic differences were found between these two groups.The AML patients with normal chromosome karyotypes are more likely to have a high BAALC expression(68%)compared with those with abnormal chromosome karyotypes(23%,?~2=12.093,P= 0.001).AML patients with normal cytogenetics and high BAALC expression shows significant lower CR rate (65%)compared with those with low BAALC expression(84%,?~2=6.573,P=0.013). Conclusion High BAALC expression may define an important risk factor in AML with normal cytogenetics and predicts an adverse prognosis.

Objective To observe the diurnal variation of intraocular pressure(IOP)measured with Goldmann applanation tonomoter(GAT)in patients with primary open angle glaucoma(POAG),normal tension glaucoma(NTG)and healthy controls,and to compare the differences of diurnal variation curves between two eyes of each subject and define the distribution of the peak of IOP. Design Prospective case series.Participants POAG patients,NTG patients and healthy controls.Methods The diurnal variation of IOP in the two eyes of each of 30 POAG patients,30 NTG patients and 30 normal controls were investigated and the distributions of the peak IOP were observed.Main Outcome Measure Intraocular pressure.Results Measured with GAT,6.7% right eyes and 10.0% left eyes of normal people,20.0% right eyes and 23.3% left eyes of NTG patients,and 23.3% right eyes and 20.0% left eyes of POAG patients showed peak IOP at the time points of out-office period.Conclusions POAG patients,NTG patients and normal controls have asymmetric IOP diurnal variation.The two eyes of one individual cannot always be treated as the same.The IOP peak can occur at the time point during the out-office time.Measure IOP in office-time only may miss the dynamic information of IOP.
