One hundred and thirty-six adult patients with type 2 diabetes ( ≥40 years, body mass index > 24) were assigned to the low-dose Mefformin, high-dose Mefformin, and control groups. Plasma lactic acid level was detected with ultraviolet enzyme kinetics assay. Our data showed that plasma lactic acid of the low-dose or high-dose mefformin group was significantly higher than the control group (2.314 vs. 2.511, P<0.05 ), although there was no significant difference between the low-dose and the high-dose Mefformin group. In all the 3 groups, increased lactic acid ( > 2. 2 mmol/L) was found in some patients ( Mefformin group vs. Control group: X2 = 7.43, P < 0.05 ), and no lactic acid > 5.0 mmol/L was found. Insulin resistance index and hemoglobin Alc were similar between the 3 groups. Thus, mefformin may not increase the risk of lactic acidosis in diabetic patients with normal cardiorespiratory and renal function.

AIM: To observe the effect of intraocular lens ( IOL) implantation on visual acuity and contrast sensitivity in patients with cataract.
METHODS: Fifty - eight cases ( 72 eyes ) cataract patients with regular cornel astigmatism, in our hospital from May 2014 to May 2015 were randomly divided into two groups to undergo phacoemulsification and IOL implantation: the observation group: 29 cases (36 eyes) received multifocal toric IOL implantation; the control group: 29 cases (36 eyes) received monofocal toric IOL implantation. Uncorrected distance visual acuity ( UCDVA), uncorrected near visual acuity ( UCNVA), best corrected distance visual acuity (BCDVA), the best corrected near visual acuity ( BCNVA ), total eye astigmatism, and the dark contrast sensitivity were observed for these patients at 1 and 6mo after cataract surgery.
RESULTS: There were no statistical significant difference between the two groups at postoperative 1, 6mo on UCDVA, BCNVA, BCDVA and total eye astigmatism(P>0. 05). UCNVA of observation group at 1 and 6mo were better than those of control group ( P <0. 05); there were statistically significant difference in high frequency comparison at the sixth postoperative months (P<0. 05).
CONCLUSION: Both monofocal toric IOL implantation, and aspheric multifocal toric IOL implantation for cataract with regular corneal astigmatism are effective to improve visual acuity. But the latter treatment would contribute to the improvement of uncorrected near visual acuity and the dark contrast sensitivity.

Objective To study the MRI manitestation of juvemle acute pure cartilage fracture of the knee joint.Methods The MRI changes of cartilage,subcartilage low signal line and subcartilage bone were analysed retrospectively in 26 juvenile patients with acute pure cartilage fracture confirmed by arthroscopy.Sagittal and coronal MRI scanning were performed in 26 patients.Using fast low angle shot fat saturation T_1-weighted image(FLASH-FS-T_1WI)sequences,spin echo T_1-weighted image(SE-T_1WI)and fast imaging with steady-state precession three dimensional fat saturation T_2-weighted image(FISP-3D-FS- T_2WI)sequences in sagittal plane,SE-T_1WI and multi echo data image combination T_2-weighted imaging (MEDIC or ME-T_2WI)in coronal plane.Using ME-T_2WI sequence,axial plane MRI scanning in 5 patients.Results Twenty-seven sites of 26 patients include 8 patella,7 femoral medial condyle, 11 femoral lateral condyle and 1 tibial plateau.Three types pure cartilage fracture were observed,totally defect of the cartilage in 7 sites(include 3 patella,2 femoral medial condyle,1 femoral lateral condyle and 1 tibial plateau),fissuring fracture in 3 sites(include 2 femoral medial and 1 femoral lateral condyles), superficial defect of the cartilage in 17 sites(include 5 patella,3 femoral medial and 9 femoral lateral condyle).Corpus liberum was found in 21 patients'knee joints by arthroscopy,but only 3 cases by MRI. Bone bruise was detected,and subcartilage low signal lines were normal.Conclusion Using FLASH-FS- T_1WI,SE-T_1WI,FISP-3D-FS-T_2WI and ME-T_2WI sequences,sagittal and coronal MRI scanning in femoral and tibial plateau pure cartilage fractures,and using ME-T_2WI sequence axial scanning in patella r cartilage fractures may show the position,extension and types of the acute pure cartilage fracture of the knee joint. MRI is the hest non-invasive method for studying cartilage fracture.

Objective To investigate the effect of Bunao capsule on learning,memory and antioxidative abilities of rats with Alzhheimer’s disease(AD)induced by D-galactose combined with amyloid β-protein(Aβ25-35 ),and provide experimental basis for the prevention and treatemtn of AD. Methods A total of 90 SD male rats were randomly divided into model control group,piracetam group,sham operated group,Bunao capsule(0.79,1.58,3.15 g·kg-1 )groups(n= 15 each).The rat models were established by intraperitoneal injection of D-galactose and injection of Aβ25-35 into the bilateral lateral cerebral ventricle.Then rats were given corresponding drugs by gavage in different groups for 8 weeks.The learning and memory abilities were meseured by Morris water maze test.The morphology of brain cells was observed by HE staining.The activities of glutathione peroxidase(GSH-Px)and superoxide dismutase( SOD),and the malondialdehyde( MDA)contents in the brain tissues were measured by spectrophotometry. Results The target quadrant residence time was(20.39±7.75)s and(20.82±5.09)s in Bunao capsule (1.58,3.15 g·kg-1 )groups,which were significantly increased as compared with that in model control group[(12. 35 ± 6.95)s](P<0.01).Brain nerve cell morphology in Bunao capsule(1.58,3.15 g·kg-1 )groups was obviously improved as compared with that in model control group,and was close to that in sham operated group.The activities of GSH-Px and SOD were significantly increased,and MDA contents decreased in Bunao capsule groups as compared with those in model control group (P<0.01). Conclusion Bunao capsule can dose-dependently improve the learning,memory and antioxidative abilities of AD rats.The mechanism may involve upregulation of antioxidative enzyme activities and removal of oxidative products.
