ABSTRACT
·AIM: To compare the visual quality after different multifocal lens (MIOL) implantation in cataract patients. ·METHODS: Totally 78 cases (78 eyes) of cataract patients who receiving phacoemulsification and implantation of different MIOL were enrolled from February 2016 to June 2017 in our hospital. According to the different type of implanted MIOL, the 78 cases (78 eyes) were divided Group A,B and C,each group was 26 cases (26 eyes). Patients in the Group A were implanted regional refraction MIOL SBL-3; patients in the Group B implanted step progressive diffraction MIOL SN6AD1;patients in the Group C implanted all - optical plane diffraction MIOL Tecnis ZMB00. The visual acuity, contrast sensitivity,defocus testing,contrast visual acuity and satisfaction of visual quality were compared in 3 groups at postoperative 3mo. · RESULTS: There was no statistically significant difference in postoperative adverse reactions between the three groups (P>0.05). There was statistical difference in uncorrected intermediate visual acuity, uncorrected near visual acuity, distance - corrected intermediate visual acuity and distance- corrected near visual acuity in 3 groups (P < 0. 05), and those in the Group C were significantly worse than those of Group A and B (P<0.05). There was statistical difference in contrast sensitivity at four spatial frequencies (3,6,12,18c/d) in light and light glare and three spatial frequencies (3, 6, 12c/d) in dark and dark glare in 3 groups (P<0.05), and those in the Group A were significantly better than those of Group B and C (P<0.05). According to the defocus testing of 3 groups,the visual acuity at -1.5D,-2.0D and-2. 5D in Group A and B was significantly higher than Group C (P<0. 05). There was statistical difference in contrast visual acuity at 20% and 9% of contrast ratio in 3 groups (P<0.05),and those in Group A were significantly better than Group B and C(P<0.05). There was statistical difference in visual quality satisfaction in 3 groups (P<0.05), and that in the Group A was significantly better than that of Group B and C (P<0.05). ·CONCLUSION:The region refraction MIOL SBL-3 not only could provide better distant, intermediate and near visual acuity, but also could provide better contrast sensitivity and contrast visual acuity, thereby greatly increase visual quality satisfaction.

ABSTRACT
AIM: To investigate the effect of scleral slap invagination and trabeculectomy combined with amniotic membrane implantation in the treatment of glaucoma.?METHODS:From May 2013 to June 2017, 98 cases (116 eyes ) with glaucoma were treated in our hospital. According to the random number table method, the patients were divided into two groups: the observation group of 45 cases (58 eyes) with scleral slap invagination surgery combined with amniotic membrane transplantation into operation, the control group of 53 cases ( 58 eyes ) with trabeculectomy combined with amniotic membrane implantation. Postoperatively patients were followed up for 3mo to observe IOP control;using MEN-C90 type blood rheology analyzer to detect the whole blood viscosity, plasma viscosity, hematocrit and blood viscosity changes, using the Doppler flow imaging ( CDFI) technique for the detection of ophthalmic artery end diastolic velocity ( EDV ) , RI, and the peak systolic velocity ( PSV ) and other hemodynamic parameters change.?RESULTS:One week and 3mo after the surgery, mean IOP of the observation group was 12. 18 ± 0. 98mmHg, 12. 23 ± 0. 94mmHg, the control group was 14. 49 ±1. 64mmHg, 14. 62 ± 1. 59mmHg, the difference was statistically significant (P<0. 05); IOP successful-control rate of observation group after operation was 81. 0％, more than that of the control group ( 61. 3％), the difference was statistically significant (P<0. 05). At 1wk and 3mo after operation high blood viscosity, plasma viscosity, hematocrit and blood viscosity of two groups decreased significantly compared with the preoperative (P<0. 05); those of the observation group were better than those of the control group (P<0. 05). At 1wk and 3mo after operation, EDV and PSV of the two groups increased significantly, RI decreased significantly, compared with the preoperative differences were statistically significant ( P < 0. 05 ), those of the observation group were better than those of the control group (P<0. 05).?

ABSTRACT
<p><b>OBJECTIVE</b>To compare the efficacy and safety of BD regimen combined with cyclophosphamide(CTX) and pirarubicin chemotherapy(P-CAD) for patients with relapse/refractory multiple myeloma(MM).</p><p><b>METHODS</b>Twenty-eight cases of relapse/refractory MM were enrolled in a group of P-CAD regimen, 36 cases of relapse/retractory MM treated with BD were used as controls. The therapeutic efficacy and adverse reactions of 2 regimens for patients with relapse/retractory MM were compared and analyzed.</p><p><b>RESULTS</b>The overall response rate (CR+NCR+PR+MR) of the 28 cases treated with P-CAD regimen was 85.7%, and the response rate (CR+PR) was 75.0%. The median progression-free survival time were 16.1 months, and the average survival time were 30.6 months, while the overall response rate of the 36 patients treated with BD regimen was 63.9%, and the response rate was 55.6%. The median progression-free survival time were 13.7 months, and the average survival time were 26.7 months. The adverse reactions of 2 groups included gastrointestinal reactions, peripheral neuropathy, fatigue, skin rashes, leucopenia and thrombocytopenia, and they were all well tolerated.</p><p><b>CONCLUSION</b>BD regimen combined with cyclophosphamide and pirarubicin chemotherapy can improve the response rate of patients with relapse/refractory multiple myeloma, and shows the trend of prolonging PFS and survival times.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of human umbilical cord-derived mesenchymal stem cells(HUC-MSC) on the proliferation and differentiation of NB4 treated with all-trans retinoid acid (ATRA) and its underlining mechanisms .</p><p><b>METHODS</b>Human umbilical cord mesenchymal stem cells were isolated from umbilical cord of newborns. Co-culture system was established by HUC-MSC and NB4 in vitro. The experiment was divided into 4 groups: NB4 group (NB4 cells alone) , NM group (NB4 cells co-cultured with HUC-MSC) , NA group (NB4 cells treated with ATRA) , NMA group (NB4 cells co-cultured with HUC-MSC and treated with ATRA) . NB4 cells were counted by a microscopy, NB4 proliferation was monitored by CCK-8 assay, NB4 differentiation was assessed by Wright ' s staining and nitroblue tetrazolium reduction test. IL-6 levels in the culture supernatant of different groups were tested by ELISA kit. Quantitative PCR was used to detect the transcription level of CDKN1A, CCND1 and Survivin.</p><p><b>RESULTS</b>NB4 and HUC-MSC in the co-culturing systems were in good condition with a slight repression of NB4 proliferation by HUC-MSC. HUC-MSC could collaborate with ATRA to induce significant NB4 differentiation. Consistent with this finding, IL-6 expression levels of co-cultured groups were remarkably higher than that in any other groups or the group of HUC-MSC alone. The quantitative PCR analysis showed that the levels of CDKN1A and CCND1 mRNA expression were increased or decreased respectively in the co-cultured groups.</p><p><b>CONCLUSION</b>HUC-MSC co-culture can reduce proliferation but promote the differentiation of NB4 cells, suggesting that this effect may be closely related with the secretion of IL-6 which can affect the expression of some factors in vitro.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical features and genetic diagnostic method of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).</p><p><b>METHODS</b>A systematic study on the clinical manifestations, neuroimaging characteristics, therapeutic measures and molecular genetics was performed. An investigation on the onset and hereditary pattern of the family was also done.</p><p><b>RESULTS</b>The main clinical features including poor memory and history of stroke were found. And no risk factors of hypertension and arteriosclerosis were found. A positive family history was confirmed. Neuroimaging examination showed multiinfarct lesions and leukoencephalopathy. All these features are in conformity with those of CADASIL. A mutation in the third and fourth exon of the NOTCH3 gene was identified in the 10 cases of 4 generations. The clinical or subclinical onset in the 10 cases was consistent with classical autosomal dominant inheritance.</p><p><b>CONCLUSION</b>The clinical and molecular genetic features of the family accord with CADASIL.</p>
