OBJECTIVETo investigate the effect of U-shaped gypsum functional fixation after closed manipulative reduction for treatment of Colles' fractures.

METHODSFrom January 2011 to April 2014,47 cases of Colles fracture were treated by closed reduction and U-shaped gypsum functional fixation including 12 males and 35 females with an average age of 54.8 years old ranging from 8 to 72 years old. The time from injury to treatment was 40 min to 3 d. The patients were closed fractures without neurovascular injury. After manual reduction and U-shaped gypsum functional fixation, the thumb of injury hand were traction by contralateral hand, and other fingers of injury hand were taken flexion to exercise grip function. According to the situation of fracture healing, plaster was removed at 4 to 8 weeks' fixation, the wrist joint functional exercise was strengthened after plaster removed.

RESULTSAll patients were followed up from 6 to 12 months with an average of 6.4 months, the fracture healing time was 4 to 8 weeks. According to the Cooney wrist function scoring: the result was excellent in 44 cases, good in 2 cases, 1 case.

CONCLUSIONU-shape gypsum functional fixation for treatment of Colles fracture limits the activity of thumb and extensor tendon, can reduce shortening of radial by traction of the injury thumb with the contralateral hand; it is good for blood circulation of hand and wrist, and swelling.

AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

Background Our previous study demonstrated that curcumin can induce the apoptosis of retinal pigment epithelial (RPE) cells and herein inhibit the proliferation of RPE cells,and it is proved that the intravitreous injection of 0.1mg curcumin has less adverse effect to ocular tissue, inferring a good applicative prospect in clinic. Objective The goal of this experiment was to evaluate the effectiveness of curcumin on the prevention and treatment of experimental proliferative vitreoretinopathy (PVR). Methods PVR models were induced by injection of 0.1ml RPE cells (containing 2×106 cells) into vitreous cavity in 40 eyes of 20 healthy and mature New Zealand albino rabbits.0. 1ml curcumin(0. 1 mg) was then injected into lateral eye of each model rabbit immediately following the injection of RPE cells,and the equal volume of normal saline solution containing 0. 5‰ DMSO was injected into the fellow eye of each model rabbit as controls. On 1,3,7,14,21 and 28 days after injection, the changes of cornea, aqueous humor, lens, vitreous and fundus were examined and recorded by slit lamp biomicroscope, indirect ophthalmoscope,fundus color camera and B-type ultrasonograph to evaluate the inflammatory response. The incidence rate of retinal detachment was calculated and compared between curcumin group and control group. Results The inflammatory reaction in anterior chamber and misty opacity in vitreous were found from 1 day through 3 days after injection, but no obvious proliferative strap and retinal detachment in all of the experimental eyes. On the 7th day after injection, inflammatory reaction was extinct in the anterior chamber of rabbit eyes, and proliferative strap occurred in 14 eyes(75% ) in the control group but only 2 eyes (10% ) in curcumin group,showing significant difference between these two groups (P<0. 01). No retinal detachment was seen in both the two groups. On 14,21 and 28 days after injection, the incidence rate of retinal detachment was 55% ,80% ,95% respectively in control group and that of curcumin group was 10% ,15% ,15% respectively,presenting considerably differences between two groups (P<0. 01, P<0. 01 ,P<0. 01 ). Conclusion Injection of curcumin into vitreous cavity can effectively inhibit the occurrence and development of PVR in rabbit.

Objectives To analyze the spectrum of renal diseases associated with monoclonal gammopathy and unrelated renal diseases.Methods Hospitalized patients in Peking Union Medical College Hospital who underwent renal biopsy between January,2013 and December,2015.They had monoclonal gammopathy on serum protein electrophoresis (SPE),serum immunofixation electrophoresis (IFE),urine IFE and/or serum free light chain (FLC).64 patients met the inclusion criteria and were classified as monoclonal gammopathy of renal significance (MGRS) (n=36),monoclonal gammopathy of undetermined significance (MGUS) (n=17) and hematologic malignancy (n=11).Results Renal lesions in MGRS subgroup included light chain amyloidosis (n=28,77.8％),light chain deposition disease (n=7,19.4％),and fibrillary glomerulopathy (n=l,2.8％).eGFR in light chain amyloidosis subgroup differed significantly,compared with light chain deposition disease [eGFR 93 ml· min-1 · (1.73m2)-1 vs 28 ml· min-1 · (1.73 m2) 1,P ＜ 0.01],as well as HTN incidence (35.7％ vs 100.0％,P ＜ 0.01).Renal diseases in MGUS subgroup included membranous nephropathy (n=10,58.8％),focal segmental glomerulosclerosis (n=3,17.6％),diabetic glomerulopathy (n=l,5.9％),Henoch-Schonlein purpura nephritis (n=l,5.9％),anti-glomerular basement membrane disease concurrent with membranous nephropathy (n=l,5.9％) and glomerulomegaly (n=l,5.9％).Various renal lesions related/unrelated to hematologic malignancy were seen in third subgroup,including light chain cast nephropathy (n=3,27.3％),tubulo-interstitial lesions (n=2,18.2％),light chain amyloidosis (n=1,9.1％),light chain deposition disease(n=1,9.1％),IgA nephropathy (n=1,9.1％),mesangial proliferative glomerulonephritis (n=l,9.1％),endocapillary proliferative glomerulonephritis (n=1,9.1％) and acute tubular necrosis (n=1,9.1％).Positive rates of SPE,serun IFE and urine IFE in MGRS subgroup were 40.6％,52.8％ and 69.4％,respectively.Positive rates of SPE,serum IFE and urine IFE in MGUS subgroup were 68.8％,100.0％ and 37.5％,respectively.Positive rates of SPE,serum IFE and urine IFE in hematologic malignancy subgroup were 54.5％,72.7％ and 81.8％ respectively.MGRS and MGUS subgroups differed significantly in positive rate of serum IFE (P ＜ 0.001).Abnormal rates of serum FLC ratio in above three subgroups were 83.3％,17.6％ and 90.9％,respectively,with that in MGUS group being significantly lower than the rates in other two groups (P ＜ 0.001,respectively).Conclusions The significance of monoclonal gammopathy in patients with renal disease should be evaluated by other clinical data,as well as renal pathology.

Background Inheritance is one of main causing-disease factors in congenital cataract.So the screen of causing-disease gene in congenital cataract patients is a critical step.Objective This survey was to investigate the molecular characteristics of a Chinese pedigree with a special crystalline autosomal dominant congenital cataract(ADCC) in Shanxi province.Methods This study was approved by Ethic Commission of Shanxi Eye Hospital.Informed consent was obtained from each subject before any medical examination.Twenty-two families from a pedigree with special crystalline were included in this study.The family members received regular ophthalmologic and general examinations to rule out any concomitant disorders.Blood samples were obtained to extract the DNA from all the subjects.Twenty-two fluorescent labeled microsatellites were selected from 17 causing genes of ADCC and amplified and screened for the linkage analysis.LOD was calculated and the candidate gene was directly sequenced.Results Ten individuals with congenital cataract were found in the family with the similar phenotype.The inheritance mode complied with the autosomal dominant pattern.Linkage analysis indicated a gene chain at D2S325 and D2S2358 with the LOD value 1.20(θ =0) and 0.22(θ =0).A known c.C70A(p.P23T) missence mutation at the coding region of CRYGD gene was detected by direct sequence.Conclusions A missense mutation P23T of the CRYGD gene cause the autosomal dominant congenital nuclear cataract with the special phenotype.

OBJECTIVETo analyze the three-dimensional changes of pharyngeal airway in patients with skeletal Class III malocclusion after the combined orthodontic and orthognathic treatment.

METHODSTwenty patients (9 males, 11 females) and 40 subjects with normal occlusion were involved in the study. Cone-beam computed tomography (CBCT) were performed on patients one week and six months after treatment. Raw data were reconstructed into three-dimensional model and sagittal and transversal measurements, cross sectional areas, partial and total volumes were computed.

RESULTSAfter treatment, the sagittal diameters of each section were significantly reduced by (2.7 ± 3.5), (3.0 ± 3.8), (2.7 ± 3.3) mm, respectively (P < 0.05). The transversal diameter of laryngopharyngeal airway constricted significantly by (4.8 ± 4.1) mm (P < 0.05). Cross sectional areas and volumes of each part in patients after surgery were significantly narrower compared with those of the controls.

CONCLUSIONSAfter combined therapy the pharyngeal airway space decreased.
