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.

OBJECTIVETo investigate the immunological activity of Streptomyces polysaccharide (SMP) on normal and immunosuppressed mice.
METHODSThe effect of SMP on the proliferating activity of normal mouse splenocytes was tested in the mixed lymphocyte culture, and the changes of peripheral blood T lymphocytes were evaluated with acid a-naphthyl acetate esterase (ANAE) method. The ratio of Lyt2+ and L3T4+ T cell subsets was measured by flow cytometry.
RESULTSSMP stimulated obvious proliferation of mixed lymphocytes, showed protective effects on T lymphocyte and increased the ratio of Lyt2+ and L3T4+ cell subsets to nearly normal level in immunosuppressed mice.
CONCLUSIONSSMP can regulate the immune function in mice.

ObjectiveTo study the clinical features, arterial involvement, therapeutic strategies and outcomes of Takayasu arteritis (TA). MethodsThe clinical symptoms, arterial images, inflammatory parameters and follow-up information of 173 patients with TA were retrospectively studied. Comparisons between groups were performed by t-test. ResultsThere were 136 female and 37 male patients in this study. The mean age at onset was(26±11 ) years. Hypertension, pulse deficit or asymmetrical pulse, and fever were present in 46.6%, 41.1%, 28.7% of patients, respectively. The distribution of arterial involvement were 64.7%in aorta, 9.8% in pulmonary artery, 19.1% in innominate artery, 65.9% in common carotid arteries, 65.3%in the subclavian artery, 36.2% in the renal artery, 12.1% in the vertebral artery, and 5.8% in coeliac axis.Elevated erythrocyte sedimentation rate(ESR) was found in 61.0% patients. Active tuberculosis or history of tuberculosis was implicated in 45 patients(26.0%). Ten patients(5.8%) were hepatitis B virus carriers.Among 105 followed-up patients, 98 patients(94.2%) achieved persistent remission, 17 patients relapsed when corticosteroids were tapered. ConclusionCorticosteroids combined with or steroid alone, supplemented with endovascular intervention procedures or surgical bypass procedures when necessary, can effectively control the clinical symptoms and inflammatory parameters and improve the quality of life of patients.

0.05).Conclusions The reduced expression of HLA-G on placenta in ICP patients may alter the maternal-fetal immune response and thus be involved in the pathogenesis of this disorder. Dexamethasone can upregulate the expression of HLA-G on placenta.The 14 bp deletion polymorphism in exon 8 of HLA-G gene might not have a significant influence on the development of ICP.

Objective To evaluate the safety of coronary intervention using iodixanol in patients with diabetic renal insufficiency.Methods Clinical data of 97 patients with diabetic renal insufficiency undergoing coronary intervention during June 2004 to June 2006 were retrospectively analyzed,50 of them with iodixanol,an iso-osmolar contrast medium (iodixanol group),and 47 with iopromide,a hypotanic contrast medium (iopromide group).Judkin's coronary angiography showed 167 diseased vessels in the patients,65 in anterior descending branches,44 in circumflex branches,and 58 in right coronary arteries. Levels of serum creatinine and blood urea nitrogen were determined before percutaneous coronary intervention (PCI),on the day of the procedure,the 3rd and 7th days after PCI,respectively,as well as radiocontrast media-induced nephropathy (CIN) was observed.Results Totally,192 drug-eluting stents were successfully implanted in 167 diseased vessels,and all patients' angina pectoris symptom disappeared soon after the procedure,with a full success.No acute or subacute stent thrombosis and major adverse cardiac events (MACE) occurred.Two patients (4%) in iodixanol group and 10 (21%) in iopromide group got CIN,with a statistical significance (P

Objective To study the role of Mycoplasma genitalium(Mg)infection in chronic non- bacterial prostatitis.Methods Culture and two PCR systems were performed on prostatic secretion specimens from 487 patients with chronic non-bacterial prostatitis and 75 health men in Changchun regions. Results positive rate of Mg in the prostatic secretion from the 487 patients was 7.39% (36/487);In the controls,the positive rate of Mg was 1.33%(1/75).The differences between the two groups were statistically significant (X~2=3.88,P

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.
