AlM:To compare the differences of tilt and decentration of two aspheric posterior chamber intraocular lens ( PC-lOL) implantation by ultrasonic biomicroscope ( UBM) .METHODS:Thirty-seven patients ( 45 eyes ) underwent cataract surgery were distributed to two groups randomly. Group A was implanted with Akreos AO ( Bausch &Lomb; four-haptic ) while group B implanted with ZCB00 ( Abbott Medical Optics, lnc. AMO; two-haptic) . All eyes underwent standard phacoemulsification with intraocular lens implantation. Diameter of capsulotomy was recorded. One month postoperatively, vision, best-corrected visual acuity ( BCVA) assessment, slit lamp examination, and anterior chamber depth ( ACD ) measured by UBM were performed. Tilt and decentration were measured horizontally and vertically, and total tilt and decentration were calculated by geometry method.
RESULTS:No statistical difference was found in BCVA and diameter of capsulotomy between two groups ( P>0. 05). The mean ACD of group A and group B were 3. 86mm ± 0. 31mm and 4. 14mm ± 0. 31mm respectively, which showed it had statistically significant difference ( P<0. 05). Horizontal decentration, vertical decentration and total decentration of group A were 0. 15mm ± 0. 09mm, 0. 15mm ± 0. 12mm and 0. 22mm ± 0. 12mm respectively, while it were 0. 22mm ± 0. 21mm, 0. 14mm ± 0. 15mm, 0. 29mm±0. 22mm for group B. Horizontal tilt, vertical tilt and total tilt of group A were 0. 63°±0. 62°, 0. 89°±0. 85°and 1.22°±0.76°, while it were 1.36°±1.48°, 1.46°±1.62° and 2. 21°±1. 97° for group B. No statistically significance was found in tilt and decentration between group A and group B, no matter horizontally or vertically or totally (P>0. 05).CONCLUSlON:Two-haptic lOL shows no difference in tilt and decentration with four-haptic lOL postoperatively.

Glaucoma is a group of diseases which can threaten and damage the optic nerve and its visual pathway, leading to visual impairment as a result. Glaucomatous optic neuropathy is a chronic disease accompanied by apoptosis of retinal ganglion cells ( RGCs ) , visual field defect and cupping of optic nerve head. The gold standard in functional glaucoma evaluation is standard automated perimetry ( SAP) , but it is often limited to the subjective feelings of the patients. Still, visual electrophysiological techniques cannot replace the conventional inspection, but with its rapid development, it has provided a new strategy for the early diagnosis of glaucoma as a supplement because it can show changes in amplitude and latency before visual field defect. Here we review three special electroretinograms and multifocal focal visually evoked potentials in the early diagnosis of glaucoma.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.
METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.
RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).
CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

Aim To investigate the cardiotoxicity of propofol and thiopental. Methods 4day-old contracting neonatal primary myocardial cells obtained from 2-to 3-day-oldWistar rats were divided into 5 groups, with normal contrast group, and the cellcultures in groups PL, PH, TL and TH, were treated with propofol(3 ? 10-5 and3 ? 10-4 mol? L) and thiopental (1 ? 10-5 and 1 ? 10-4 mol?L) for 8 h.The con-tractility and morphology of the cells were observed and the cytoplasmic enzyme(LDH, AST, CK and ALP) release content of myocardial cell and the concentrationof electrolytes (K +, Na +, Cl - and Ca2+ ) in the medium were measured 8 h afterintravenous anesthetics administration.
