作者： Ben Simon G.J. Desatnik h. 王海燕 Jules Stein Eye Institute 100 Ste in Plaza Los Angeles CA 90095-7006 United States

Background: Opposite clear corneal incisions (OCCIs) h.ve been reported to red uce pre-existing astigmatism (PEA) during cataract surgery. Our goal was to eva luate th. effect of OCCIs on correcting PEA in cataract surgery. Meth.ds: Nonran domized prospective study. Th.rty-four patients with.PEA of greater th.n 1.5 di opters (D) underwent clear cornea ph.coemulsification cataract extraction with.3 .2-mm OCCIs (OCCI group). Th. control group consisted of 23 successive patients with.PEA h. underwent cataract extraction with.ut OCCI. Best-correcte d visual acuity, keratometry and refraction were recorded for all patients pre- operatively and post-operatively. Results: Using keratometric findings, mean as tigmatism correction was 1.3 D (±0.9 SD; decreased from 2.6 D preoperatively to 1.4 D post-operatively) in th. OCCI group but only 0.4 D in th. control group (P h. postoperatively. Vector analysis of astigmatism correction sh.wed greater ch.nge for OCCI patients (1.8 D vs 1.0 D, P=0.002). Using th. h. lladay meth.d for calculating surgically induced refractive ch.nge (SIRC), th. O CCI group sh.wed a h.gh.r value of SIRC (-1.6 D vs-0.97 D), but th.s was not s tatistically significant. Th. OCCI patients sh.wed a greater and significant ch. nge in refraction sph.rical equivalent th.n th. controls. No complications relat ed to OCCI or cataract surgery occurred during th. follow-up period. Conclusion s: Opposite clear cornea incision seems to be a simple, predictable, safe and ef fective procedure in reducing pre-existing corneal astigmatism in cataract surg ery. It h.s an enh.nced effect in correcting astigmatism compared to a single cl ear cornea incision wh.n using keratometric findings value but not wh.n using re fractive data. Future studies are needed to document th. long-term effect of OC CI and to evaluate th. correlation between incisions of different size and astig matism correction.

AIM： To evaluated th. th.rapeutic and proph.lactic effect of th.lidomide on 2, 4, 6-trinitrobenzene sulfonic acid （TNBS）-induced colitis. Th.lidomide h.s been reported to downregulate th. expression of tumor necrosis factor α （TNF-α）, IL-12, and vascular endoth.lial growth.factor （VEGF）, h.llmarks of intestinal inflammation in Croh.＇s disease （CD）. METh.DS： Male Wistar rats were divided in five groups of ten animals each. Four groups received a rectal infusion of TNBS in eth.nol. Th. first group was sacrificed 7 d after colitis induction. Th. second and th.rd groups received eith.r th.lidomide or placebo by gavage and were sacrificed at 14 d. Th. fourth.group received th.lidomide 6 h.before TNBS administration, and was sacrificed 7 d after induction. Th. fifth.group acted as th. control group and colitis was not induced. h.stological inflammatory scores of th. colon were performed and lamina propria CD4＋ T cells, macroph.ges, and VEGF＋ cells were detected by immunoh.stoch.mistry. TNF-α and IL-12 were quantified in th. supernatant of organ cultures by ELISA. RESULTS： Significant reduction in th. inflammatory score and in th. percentage of VEGF＋ cells was observed in th. group treated with.th.lidomide compared with.animals not treated with.th.lidomide. Both.TNF-α and IL-12 levels were significantly reduced among TNBS induced colitis animals treated with.th.lidomide compared with.animals th.t did not receive th.lidomide. TNF-α levels were also significantly reduced among th. animals receiving th.lidomide proph.laxis compared with.untreated animals with.TNBS-induced colitis. Intestinal levels of TNF-α and IL-12 were significantly correlated with.th. inflammatory score and th. number of VEGF＋ cells. CONclUSION： Th.lidomide significantly attenuates TNBS-induced colitis by inh.biting th. intestinal production of TNF-α, IL-12, and VEGF. Th.s effect may support th. use of th.lidomide as an alternate approach.in selected patients with.CD.

Objectives: Recent ch.nges in life style h.ve increased obesity, smoking and sedentary h.bits in th. entire population. Obesity and overweigh. frequency h.ve trebled in Mexico in th. last few decades. Th. presence and frequency of cardiovascular risk factors were determined in students at th.

Material and meth.ds: Anth.opometric variables, serum glucose, total ch.lesterol levels, blood h.moglobin and h.matocrit were obtained and assessed in 4814 students, 1507 recently admitted and 1507 advanced students. Results: Th. prevalence of obesity was 15.3%, sedentariness 33.8%, h.perch.lesterolemia 8.16%, smoking h.bits 15.8%, and alcoh.l consumption 12.1%. Body mass index (BMI) (23.5 ± 4 vs. 22.7 ± 4), waist/ abdomen index (0.84 ± 0.06 vs. 0.83 ± 0.06) and serum ch.lesterol (3.54 mmol/L ± 0.79 vs. 3.98 mmol/L ± 0.77) were greater in th. advanced students

作者： h.M.Soliman and M.E.Abd E1-Azim(Metallurgy Dept., Atomic Energy Auth.rity, Cairo, Egypt ) Metallurgy Dept. Atomic Energy Authority Cairo Egypt

Two low alloy steels 0.5Cr-0.5Mo-0.25V and h.5 were pack-aluminized at 900°for 4 h.by using Fe-Al powder mixture containing 48% Fe, 20.6% Al- 29.4% Al2O3 and 2% Nh.cl by weigh.. Th. microh.rdness and oxidation resistance at 900℃ of th. aluminide coatings were studied. It was found th.t pack-aluminizing improves th. microh.rdness of th. 0.5Cro.5Mo-0.25V steel wh.le it reduces th. microh.rdness of th. h.5 steel. Pack aluminizing h.gh.y improves th. oxidation resistance after 20h.exposure at 900℃ in air for th. investigated steels.

Background: Numerous studies h.ve reported on th. association between coeliac disease and th. oth.rwise uncommon enteropath.-type T cell lymph.ma (ETTL). A systematic risk assessment of more prevalent lymph.ma entities, such.as B cell and non-intestinal lymph.mas, in coeliac disease h.s not been performed. Aims: In ligh. of th. increasing number of patients diagnosed with.coeliac disease and th. unknown aetiology of malignant lymph.mas, we aimed to estimate th. distribution and risk of lymph.ma subtypes in coeliac disease. Meth.ds: We reviewed and reclassified 56 cases of incident malignant lymph.mas occurring in a Swedish.population based coh.rt of 11 650 patients h.spitalised with.coeliac disease. Th. observed numbers of lymph.ma subtypes were compared with.th.se expected in th. Swedish.population. Results: Th. majority (n = 32, 57%) of lymph.mas in th. coh.rt were nof intestinal T cell lymph.mas. Significantly increased risks were observed for B cell non-h.dgkin lymph.ma (Nh.) (standardised incidence ratio (SIR) 2.2 (95%confidence interval (cl) 1.2-3.0); 11 non-intestinal and five intestinal) and for lymph.mas of nonintestinal origin (SIR 3.0 (95%cl 2.3-5.2), 11 B and 14 T cell). Furth.rmore, 44%of patients with.B cell Nh. h.d a h.story of oth.r autoimmune/inflammatory diseases. Th. relative risks for T cell Nh. (SIR 51 (95%cl 35-68); n = 37) and for primary gastrointestinal lymph.mas (SIR 24 (95%cl 16-34); five B and 25 T cell) were markedly increased, as anticipated. Conclusion: Most lymph.mas complicating coeliac disease are indeed related to th. disease and are not of th. ETTL-type. Th.re was a remarkable aggregation of autoimmune/inflammatory disorders, female sex, coeliac disease, and B cell lymph.ma.

Neocortical neuritic plaques and neurofibrillary tangles are h.llmark neuropa th.logical lesions of dementia. Concomitant cerebrovascular lesions increase dem entia severity in patients meeting neuropath.logical criteria for Alzh.imer s disease and contribute to cognitive impairment in persons with.mild entorh.nal A lzh.imer lesions. Th.s study investigates wh.th.r individuals with.sparse neocor tical neuritic plaques experience increased odds of crossing th. th.esh.ld to cl inical dementia wh.n th.y h.ve coexistent cerebrovascular lesions. Dementia exam inations were given to 3,734 men during th. 1991- 1993 h.nolulu Asia Aging St udy examination and to 2,603 men during th. 1994- 1996 examination. Lesion quan tification was done with.ut clinical data. Among 333 autopsied men, 120 h.d deme ntia, 115 h.d marginal results, and 98 h.d normal cognition. In men with.neurofi brillary tangles, dementia frequency increased with.increasing neuritic plaque d ensity, and increased furth.r in th. presence of cerebrovascular lesions. Th. as sociation was strongest in men with.sparse neuritic plaques (1- 3/mm2) wh.re de mentia frequency more th.n doubled with.coexistent cerebrovascular lesions (45 v s 20% ). Among all dementia cases, 24% were linked to cerebrovascular lesions . Findings suggest cerebrovascular lesions are associated with.a marked excess o f dementia in cases with.low neuritic plaque frequency. Prevention of cerebrovas cular lesions may be critically important in preserving late life cognitive fu nction.
