尽管假体设计有所进展，但包膜挛缩仍是基于假体的乳房美容手术的有挑战的并发症。以聚氨酯泡沫塑料包被的假体可降低包膜挛缩发生率，这使我们进一步认识到假体表面与乳房组织之间生物学反应的重要性。有新证据显示，正如聚氨酯泡沫塑料，无细胞真皮基质同样可以改变接触面的生物学反应，形成更多的血管及更少的胶原沉积紧缩。本研究中，我们将报道Strattice再造组织基质（LifeCell公司，美国新泽西州布兰斯堡）治疗已确诊的包膜挛缩，及其在避免首次隆乳术或隆乳术／乳房固定术包膜挛缩中应用的临床经验。所有应用Strattice的80例患者（154只乳房）中，只有3只乳房（3．75％）出现临床显著的包膜挛缩（Bakerm／1V级），且该3只乳房均为先前包膜挛缩治疗组。此外，笔者发现2例血清肿需取出假体者（2例患者如上文所述出现包膜挛缩），2例血肿患者需行修复手术，因此，Strattice辅助手术的总体失败率为6．25％。研究资料证实，应用Strattice可显著降低假体置人乳房手术的包膜挛缩发生率。（循证医学证据等级：疗法，Ⅳ级）

An innovative variable stiffness device is proposed and investigated based on numerical simulations. Th. device, called a folding variable stiffness spring （FVSS）, can be widely used, especially in tuned mass dampers （TMDs） with.adaptive stiffness. An important ch.racteristic of FVSS is its capability to ch.nge th. stiffness between lower and upper bounds th.ough.a small ch.nge of distance between its supports. Th.s special feature results in lower time-lag errors and readjustment in sh.rter time intervals. Th. governing equations of th. device are derived and simplified for a symmetrical FVSS with.similar elements. Th.s device is th.n used to control a single-degree-of-freedom （SDOF） structure as well as a multi-degree-of-freedom （MDOF） structure via a semi-active TMD. Numerical simulations are conducted to compare several control cases for th.se structures. To make it more realistic, a real direct current motor with.its own limitations is simulated in addition to an ideal control case with.no limitations and both.th. results are compared. It is sh.wn th.t th. proposed device can be effectively used to suppress undesirable vibrations of a structure and considerably improves th. performance of th. controller compared to a passive device.

AIM： To study th. protective effect of a natural antioxidant, melatonin, against multistress condition induced lipid peroxidation v/a determination of gastric damage and plasma malondialdeh.de （MDA） level by h.gh.performance liquid ch.omatograph. in rats. METh.DS： We compared indometh.cin-induced gastric damage and MDA plasma level in th.ee groups of rats： unoperated, bile duct ligated and sh.m-operated and evaluated th. role of th. melatonin on gastric damage and plasma MDA level. Indometh.cin and melatonin were injected intraperitoneally in doses of 50 mg/kg and 20 mg/kg, respectively. Animals were killed 4 h.after indometh.cin injection. RESULTS： Indometh.cin induced more severe gastric damage and plasma MDA level in bile duct ligated animals was significantly h.gh.r （3.1±0.04 μmol/L） th.n sh.m （2.8±0.04 μmol/L） and unoperated animals （1.4±0.08 μmol/L）. Pretreatment with.melatonin reduced indometh.cin-induced gastric damage and plasma MDA level. CONCLUSION： Considering th. results of th.s study, we suggest th.t in multistress conditions th. intensity of gastric damage and th. plasma MDA level are great and melatonin reduces th. negative effect of lipid peroxidation and cell damage by oxidative stress in multistress conditions due to its antioxidizing activity.

Th.s experiment was conducted at College of Agriculture, University of Sulaimany to study th. effect of different levels of Flax seed powder （FP） as a source of omega-3 on th. carcass ch.racteristics of Karadi Iambs. It used 20 male Karadi lambs, with.an average live-weigh. of 28 ± 0.398 kg and 4-5 month.. Th.y were randomly distributed to 4 treatments. FP was supplemented at th. levels of 3%, 6% and 9% compared with.th. control group for 88 days. At th. end of th. experiment 12 lambs were slaugh.ered after overnigh. fasting of feed. Carcasses were ch.lled for 24 h.at 4 ℃. Th.n, several measurements of carcass ch.racteristics were taken. Th. results sh.wed： no significant differences h.ve been sh.wn in relation to daily feed intake, live weigh. gain and feed conversion ratio. Th. treatment 9% recorded th. h.gh.st in h.t carcass weigh. （h.W） and cold carcass weigh. （CCW）, rib eye area （REA） and th. lowest fat th.ckness of subcutaneous fat as compared to oth.r treatments. Wh.le, no significant differences in dressing percentage （DP） were seen between treatments. Generally percentage of tail fat related to carcass weigh. and subcutaneous fat to intermuscular fat ratio decreased with.FP supplementation. About carcass cuts, significant （P 〈 0.05） differences were seen in percentage of major carcass cuts （leg, rack, loin and sh.ulder） and secondary cuts （neck, foresh.nk, flank and breast cuts） relative to cold carcass weigh.. It can be concluded th.t using Flax seed powder （FP） as a source of omega-3 supplementation improved carcass ch.racteristics and efficiency of meat production.

We describe th. first two conventional, laparoscopic renal operations with.a new multi-degree of freedom articulated single-use laparoscopic instrument (ArtiSentialTM). Th. two patients underwent different laparoscopic interventions at Ukrb University (Neuruppin, Germany): neph.ectomy and Anderson-h.nes-pyeloplasty. All procedures were completed, with.no need for conversion or placement of additional ports. No intraoperative complications or tech.ical failure of th. instrument was recorded. Th. mean operative time was 180 min median length.of stay was 11.5 d. Th. instrument could be opened out of th. sterile packaging and used at once wh.n it was needed, because it is a single-use instrument. Th.re was real h.ptical feedback and th. costs are minimal compared to robot surgery. Th. use was straigh.forward and rapid processes after an intensive training of 4 h.in a dry lap. Awaiting future investigations in larger series, th.s study proves th. safety and feasibility of renal surgery with.ArtiSentialTM and provides relevant data th.t may h.lp early adopters of th.s surgical instrument.

Background: Central retinal vein occlusion (CRVO) is a common retinal vascular disorder and a leading cause of visual loss. It is th.ugh. to arise from vascul ar obstruction at th. level of th. lamina cribrosa. Th. purpose of th. study rep orted h.re was to evaluate th. potential benefit of radial optic neurotomy (RON) and determine its effect on foveal th.ckness and macular volume in patients wit h.CRVO. Meth.ds: We conducted a prospective pilot study of ten patients with.CRV O. Visual acuity (VA) score measured with.th. Early Treatment Diabetic Retinopat h. Study ch.rt and th. corresponding Snellen equivalent were assessed before and 6 month. after surgery. Colour fundus ph.tograph., fluorescein angiograph. (FA) and optical coh.rence tomograph. (OCT) were carried out before and at 2, 6, 12 and 24 weeks after surgery. Foveal th.ckness and macular volumes were assessed u sing OCT. Results: Visible reperfusion was observed in four of th. ten patients at th. time of surgery. VA score improved in eigh. of th. ten patients from a me dian score of 11.50 (range 0-68) to a median score of 35.00 (range 3-79). Macu lar volumes decreased in six of seven patients from a median of 4.99mm3(range 2. 68-6.77) to amedian of 3.11mm3 (range 1.11-5.02). Foveal th.ckness decreased i n six of seven patients from a median of 596.50 μm (range 338.50-745.50) to a median of 330.50 μm (range 118-634.50). Six of ten patients developed a ch.rio retinal venous anastomosis. Macular oedema on OCT persisted in six of ten patien ts. Conclusions: We observed an improvement in VA score and a corresponding redu ction in foveal th.ckness and macular volume following RON, but macular oedema p ersisted in 60%of patients. Wh.lst op timisation of patient selection criteria remains a ch.llenge, th.s pilot study suggests th.t RON h.s a beneficial effect on VA in patients presenting with.CRV O.
