OBJECTIVETo study clinical effects of inversive LISS (less invasive stabilization system, LISS) plate combined with steel wire for the treatment of Seinsheimer type V subtrochanteric femoral fractures.

METHODSFrom January 2009 to Janurary 2012, 11 patients with Seinsheimer type V subtrochanteric femoral fractures were treated with inversive LISS plate combined with steel wire, including 8 males and 3 females, ranging in age from 35 to 61 years old (averaged, 51 years old). Causes of injury: 8 patients caused by accident and 3 patients caused by falling down. According to X-ray examination, all the patients were type V subtrochanteric femoral fractures and were treated with LISS plate combined with steel wire. Merle d'Aubigne scores were used to evaluate therapeutic effects on hip.

RESULTSThe mean period of follow-up was 16 months (ranged, 12 to 28 months). All the patients obtained bone union for average 3.8 months (ranged from 3 to 4.3 months). There were no complications such as deep infection,deep vein thrombosis, pulmonary embolism and bone nonunion. According to Merle d'Aubigne scores, 7 patients got an excellent result and 4 good.

CONCLUSIONInversive LISS plate combined with steel wire for the treatment of Seinsheimer type V subtrochanteric femoral fractures is satisfactory, Which can provide stable fixation for fracture end and provide an ideal internal fixation method for treatment of this kind of fractures in the future.

BackgroundBigbag intraocular lens (IOL),due to its special conducive design to support vitreous and retina after cataract surgery in high myopia,and ensure the visualization of peripheral retinal,is closely concerned.But whether its concave design has the advantage in reducing aberrations on the basis of stability or not is worth to be studied.ObjectiveThis study was to evaluate the high order aberrations(HOA) of phacoemulsification and the Bigbag IOL implantation in patients with myopia and cataract.MethodsA retrospective case-observational study was designed.Total 39 eyes of 39 cases with cataract and high myopia were enrolled in this study.The patients were divided into Bigbag IOL group and AR40e IOL group.Phaco-chop technique and IOL implantation were performed in April to June,2010 in Tianjin Eye Hospital.Two months after surgery,the operated eyes were clinical examined and the aberrations were detected including Root-Mean-Square (RMS),coma,spherical and Trefoil.Postoperative RMS values of HOA components of the whole and interior optic with iTrace were compared.Results The operation was smoothly with the correct IOL position after two months.No complication was found.Under the 4.5 mm pupil diameters,the whole ocular HOA RMS values and coma were significantly different between Bigbag IOL group and AR40e IOL group( t =-3.296 、-3.322,P＜0.05 ),but no significant differences were seen in spherical and Trefoil aberrations ( t =- 1.256、- 0.573,P＞ 0.05 ).Regarding to the interior optic with iTrace aberration,only the coma showed the significant difference between Bigbag IOL group and A R40e IOL group( t =-2.004,P＜0.05 ),and there were no significant differences in RMS,spherical and Trefoil aberrations( t=-1.073、0.380、0.288,P＞0.05 ).ConclusionsThe Bigbag IOL,a design for high myopia,is safe and effective after implant for the high myopia with cataract.It offers more exact obligate degree and better visual quality.The chief total and interior HOA components difference between groups is coma aberration.

Background The test for visual acuity is the conventional standard for evaluating visual quality.However,there is little correlation between visual acuity and visual disability.Therefore,other clinical observations such as contrast sensitivity or straylight have been used in the clinical assessment of visual quality after cataract surgery.Objective This study was to examine the change in the amount of straylight in cataractous eyes and to evaluate the correlation of the types of cataract with visual quality.Methods A non-randomized case-controlled study was designed.Eighty eyes of 40 patients with age-related cataract were enrolled in this study,including 22 eyes with hard nucleus cataract,19 eyes with cortical cataract,23 eyes with mixed cataract and 16 eyes with posterior subcapsular cataract diagnosed based on the criteria from Lens Opacities Classification System Ⅲ(LOCS Ⅲ).The values for straylight and best corrected visual acuity (BCVA) were measured with the C-quant straylight meter and Snellen chart,respectively.The differences in the straylight values among the different types of cataract were analyzed,and the correlation of the straylight value with age or BCVA was assessed.Forty eyes of 40 age-matched normal people served as controls.Results Examination was completed in sixty-two eyes of 31 patients in the cataract group at a completion rate of 77.5％,and all the subjects in the control group finished the examination at a rate of 100％.The mean straylight value was (2.06±0.88) log in the cataract group and (1.96±0.42) log in the control group,showing a significant difference between them (t =3.251,P＜0.01).The respective mean C-quant measurements for hard nucleus cataract,cortical cataract,nuclear-cortical cataract and posterior subcapsular cataract patients were (1.96±0.42) log,(1.91 ±0.16) log,(2.05 ±0.19) log and (2.48 ±0.66) log,respectively,with a significant difference among these four groups (F =2.156,P =0.019).The highest straylight value was detected in the posterior subcapsular cataract group.The straylight value was enlarged with the increase of age with a regression equation of Y=0.0010X+ 1.025 in the hard nucleus cataract group (r =0.455,P ＜ 0.05).In addition,the negative linear correlation was found between the straylight value and BCVA in both the hard nucleus cataract group and cortical cataract group (r=-0.590,-0.697,P＜0.01).However,no correlation was found in the mixed cataract group and posterior subcapsular cataract group (r =-0.240,-0.235,P＞0.05).Conclusions The C-quant straylight meter can objectively reflect the visual function for hard nucleus and cortical cataractous eye.Posterior subcapsular cataract produces straylight and exerts a great influence on visual quality due to early glare sensation,so it should be benefit to perform surgery earlier.

Objective To explore the effect of Mycobacterium tuberculosis antigen (Mtb-Ag) on neutrophils apoptosis.Methods The fresh isolated neutrophils from healthy adults blood were cultured with Mtb-Ag for 24 h,with or without pretreatment of nuclear factor -?B (NF-?B) inhibitor N-tosyl-L-phenylanyl chloromethyl ketone (TPCK) for 30 minutes.Annexin V staining and Flow cytometry were used to measure cell apoptosis of neutrophils.NF-?B DNA binding was measured by gelelectrophorestic mobility shift assay (EMSA) in neutrophils after incubated with Mtb-Ag for 0,1,2,4,6,24 hours.Results Comparing to the spontaneous apoptosis (55%?6%) of neutrophils after culture in vitro for 24 h,treatment of Mtb-Ag (1.125 mg/ml) decreased the cell apoptosis of neutrophils (32%?3%).The NF-?B shift bands were detected at 1 h in neutrophils after stimulated by Mtb-Ag,and reached maximum peak at 2 hours,and then returned to basal levels within 24 h.Pretreatment of TPCK inhibited the anti-apoptosis role of Mtb-Ag in neutrophils.Conclusion Mtb-Ag prevents neutrophils apoptosis and its inhibitory role concerns NF-?B pathway.

Objective To statistically analyze data of blood transfusion from General Hospital of Chengdu Military Command,Mianyang field blood station,Deyang field blood station and other military medical institutions from May 12 to June 30,2008 so as to provided certain references for reasonable blood supportability in wartime and disaster.Methods A statistical analysis was done on data of blood collection and supply including self-taken blood and assembled blood,total amount of blood supply as well as the transfusion information of inpatients injured by earthquake in our hospital.Results The amount of self-taken blood was 5 111 U,the amount of assembled blood 3 380 U and the total amount of blood supply 1 0405.5 U.But blood transfusion was 4 090.6 U in 132 patients admitted into General Hospital of Chengdu Military Command.In addition,the crest-time of transfusion appeared at 96 hours after earthquake.Moreover,patients with fractures received the highest rate of blood transfusion and crush syndrome patients received the most blood transfusion and the highest per capita transfusion.Conclusions Blood supportability in earthquake is different from that in wartime and other disasters in aspects of transfusion time,blood types and blood transfusion volume.It is important to analyze the characteristics of transfusion in patients injured by earthquake for national strategy of blood supportability in disasters and for blood supportability in the wartime.

Objective To explore the effect of early enriched environment intervention on expression of neurofilament protein (NFP) in brain and the neurobehavior of filial rats with brain injury.Methods The pregnant Wistar rats of lipopolysaccharide (LPS) group were consecutively injected intraperitoneally with LPS on the 17th and 18th day of gestation while the control group only received an injection of same dose of 9 g/L saline.All premature rats,whose gestational age was less than 22 days,were removed from both groups;While the full-term newborn rats were chosen.After delivering,the uterus and placenta were taken out immediately to examine the infection situation by HE staining.Twenty-four hours after born,the brains of the newborn rats were taken out to observed the white matter damage by HE staining.LPS group was randomly divided into 2 groups:intervention group and non-intervention group.The intervention group was treated with neonatal handling and enriched environment from postnatal 8 days,while no management was performed in control group and non-intervention group.Ethological examination was tested with hanging test,and immunohistochemical technique was used to detect the expression of NFP,when the neonatal rats were 21 days old.Results There were a large amount of neutrophilic granulocyte in the uterus and placenta in LPS-treated group; In the 1-day-old rats in LPS group,brain tissue pathology test showed diffuse white matter lucencies.The scores of hanging test in control group was the highest,the ones in non-intervention group was the lowest among the 3 groups,and there was significant difference between them (Pa

12-18 years old).In each age group,children were classified according to their genders.Diffusion tensor imaging(DTI)was performed in all the children's heads.Then the angles formed by splenium corporis callosi and occipital forceps were measured in fractional anisotropy maps.All the data were analyzed statistically.Results 1.The females in infant group had the larger angles formed by splenium corporis callosi and occipital forceps.With the age increasing,the average values of angles tended to decrease gradually.But in some age groups,the average values in some cases tended to increase before it decreased.2.A statistically significant sex difference was found in infant group.In young child group,pre-school age group and adolescence group,such difference was found in angles formed by occipital forceps.Only in young child group,difference in the maximum angles of splenium corporis callosi was found.3.There was a significant difference between age groups in the angles formed by sides of occipital forceps and the minimum angles of splenium corporis callosi through one-way analysis of variance.4.The angles of occipital forceps and the minimum angles of splenium corporis callosi both had a negative correlation with ages.They both had a linear regression to ages.But,there was no correlation between the maximum angles of splenium corporis callosi and ages.Conclusions Sex differences might exist in the angles formed by both sides of occipital forceps and splenium corporis callosi.The angles formed by sides of occipital forceps and parts of angles of splenium corporis callosi might decrease when the age increases.Diffusion-weighted technology can be used to study the age and sex difference in angles formed by splenium corporis callosi and occipital forceps in children.

Objective: To study the pharmacological effects of Zengxuean capsule (Radix Astragali, Indigo Naturalis, Cordyceps, etc) on anti inflammation.Methods:A few conventional models, such as the mouse pinna swelling induced by croton oil, were employed to determine the anti inflammatory activities of Zengxuean capsule.Results: Zengxuean capsule obviously inhibited the swelling of mouse pinna induced by croton oil, suppressed the edema of rat hind paw elicited by injection of 1% carrageenan, significantly depressed the increase of peritoneal capillary permeability in the xylene induced mice, and greatly decreased proliferation of granuloma led by implanting cotton pellet. It had an abatement effect of algesia induced by heat with tail flick method, and could not inhibit the swelling of pinna led by croton oil when mouse's adrenal was resected.Conclusion: Zengxuean capsule is an effective medicine on anti inflammation, and its acitivity is realized by adrenal cortical system.
