AlM:To compare the functional and cosmetic effects of two different surgical techniques for congenital ptosis.
METHODS: The patients were divided into four groups according to the operation method: Patients undertook bilateral fascial suspension surgery as Group A ( 42 eyes of 21 cases ); Patients undertook bilateral levator muscle shortening surgery as Group B ( 38 eyes of 19 cases );Patients undertook unilateral fascial suspension surgery as Group C ( 24 eyes of 24 cases ); Patients undertook unilateral levator muscle shortening surgery as Group D (29 eyes of 29 cases). Each group patients were followed for postoperative function and appearance effect.
RESULTS: 1 ) Early postoperative of two operation function success rate was up to 100%, the function of levator muscle shortening surgery was 97. 01% in the late postoperative, was higher than bilateral fascial suspension surgery (87. 88%), with statistical difference in both surgerys (P<0. 05). 2) Appearance effect of two kinds of operation method in early postoperative had no statistical difference (P >0. 05); ln the late postoperative, the mean grades for “Lid Contour” and “Lid Crease” of Group B were better than that of Group A (P<0. 01). While the mean grades for “Lid Contour”, “Symmetry of Lid Height” and “Lid Crease” of Group D were similarly better than that of Group C (P<0. 01).
CONCLUSlON: Two kinds of operation method have good effects on the treatment of congenital ptosis. ln terms of cosmetic effect, levator muscle shortening surgery is better.

OBJECTIVETo investigate the association between neuronal nicotinic acetylcholine receptor alpha 7 subunit (CHRNA7) gene and schizophrenia.

METHODSThe three polymorphisms rs2337980, rs1909884, rs883473 in CHRNA7 gene were detected based on PCR and polyacrylamide gel microarray in 129 schizophrenic trios. The results of genotyping were analyzed by haplotype relative risk analysis based on haplotype(HHRR), transmission disequilibrium test(TDT) and hyplotype analysis.

RESULTS(1)The HHRR analysis suggested that there was significant differences in rs2337980 allele frequencies between schizophrenia group and dummy control group(P= 0.017); (2)In TDT test, there may be transmission disequilibrium between rs2337980 and schizophrenia, the heterozygous parents excessively transferred the C allele to patients (P= 0.021); (3)The haplotype between rs2337980 and rs1909884 as well as the hyplotype among rs2337980, rs1909884 and rs883473 may have significant association with schizophrenia (global P= 0.034; global P= 0.027), the T-C and T-C-T hyplotype may have transmission disequilibrium with schizophrenia.

CONCLUSIONThere may be association between CHRNA7 gene polymorphisms and schizophrenia, the variant allele T in rs2337980 may have a protective effect to schizophrenia.

Objective To investigate the value of three-dimensional speckle tracking imaging (3D-STI) in assessment of left ventricular (LV) strains. Methods Thirty healthy young adults examined by two-dimensional speckle tracking imaging (2D-STI) and 3D-STI. And the results of LV measurements were compared, which included mean peak systolic longitudinal strains, radial strains and circumferential strains. Also, the time consumption of these two methods was compared. Results The time needed for 3D-STI in acquisition and analysis of the images were (309.3±23.4)s, (305.5±11.2)s, while the time for 2D-STI were (490.6±14.4)s, (1261.4±39.9)s. The differences were signiifcant(t=-21.81, 69.94, both P<0.01). The global mean peak systolic radial strains was (48.59±7.68)%by 3D-STI and (33.25±7.27)%by 2D-STI. The difference was signiifcant(t=9.16, P<0.01). The global mean peak systolic longitudinal and circumferential strains were (-17.66±3.14)%, (-17.13±2.29)% by 3D-STI and (-21.35±2.46)%, (-21.97±3.84)% by 2D-STI. The differences were signiifcant(t=5.33, 5.99, both P < 0.01). The 3D-STI strains were different at different levels of LV. The longitudinal, circumferential and radial 3D-STI strains were largest at middle levels. However, 2D-STI strains didn′ t show such trend. Peak strains measured by 3D-STI and 2D-STI showed high inter-observer and intra-observer agreement in Bland-Altman chart. Conclusion 3D-STI is a novel, convenient and reproducible method to evaluate the strains of LV.

OBJECTIVETo explore the value of fluorescence in situ hybridization (FISH) technique in diagnosis of variant Ph chromosome translocation (VT) and Ph chromosome-negative chronic myelocytic leukemia (CML).

METHODSNine CML patients with VT and 2 Ph chromosome-negative CML patients confirmed by R banding were assayed with dual color-dual fusion BCR/ABL probe by FISH.

RESULTSThe 9 patients with VT involved chromosomes 1, 3, 5, 12, 13, 15, 17 and 21 besides chromosomes 9 and 22, and some of them showed recurrent aberrations; FISH results were positive and the signal feature was 2R2G1Y. The 2 Ph-negative CML patients had normal karyotypes; FISH was positive and the signal feature was 1R1G2Y and 1R1G1Y respectively.

CONCLUSIONFISH can provide better diagnosis for CML with VT and Ph-negative CML. Abnormal karyotype and marker gene changes can be assessed based on the signal feature of the positive cell. So FISH is a complementary method to banding technique in diagnosis of CML.

Objective To evaluate the clinical characteristics and surgical treatment of renal stenosis resulting from fibromuscular dysplasia ( FMD ). Methods 16 cases from 1998 to 2011 were reviewed,the average age was (28 ± 13 ) years old. Among them, all patients suffered refractory hypertension and only one presented renal dysfunction. Aorto-renal bypass was performed in 2 cases.Resection and reconstruction was performed in 2 cases,balloon angioplasty in 10 and stent implantation in 3.Results There was 1 death peri-operatively.13 out of 15 cases were followed-up with no death.Significant decline of blood pressure [ (134 ± 14 )/( 83 ± 8 ) mm Hg vs.( 151 ± 17 )/( 96 ± 16 ) mm H g ( P ＜ 0.01 ) ]and 100％ effective rate were observed.The creatine level were preserved after surgical treatment [ (61 ±22) μmol/L vs.(69 ± 22) μmol/L,(P ＞ 0.05 ) ] with 4 cases improved and the other 9 stable.12 patients received ultrasound surveillance with only one case of 20％ restenosis. Conclusions Renal stenosis due to FMD are most common in children and the youth with hypertension as major presentation. Balloon angioplasty is the first choice of surgical treatment with positive efficacy.

Objective To retrospectively analyze the geometrical characteristics of abdominal aortic aneurysms undergoing endovascular treatment in a single medical center.The long-term effects as well as the strategies for the prevention and treatment of complications have been reviewed.Methods From January 2003 to December 2010,clinical data and geometrical parameters of 344 cases undergoing endoluminal repair of abdominal aortic aneurysms were analyzed retrospectively.Results The diameter and length of proximal neck was (23 ± 3 )mm and ( 26 ± 12) mm respectively.The angle between the neck and the abdominal aortic aneurysm was (25 ± 28) degree.The surgical success rate was 99.7％.The average follow-up time was 32.9 months (3 -84 months) with follow-up rate 81.8％ (279/341).The mortality was 1.1％ (3/279),the re-intervention rate was 10.4％ (29/279) and the overall complication rate was 12.9％ ( 36/279),including endoleak of 5.7％ ( 16/279 ),stent-graft migration of 1.1％ ( 3/279 ),aneurysm expansion or rupture of 5.4％ ( 15/279 ),and other complications like limb occlusion.Severe infrarenal aortic neck angulation ( ＞ 60 degree) was associated with type Ⅰ endoleak ( P =0.010 ).Conclusions A careful preoperative case selection and evaluation is the key for a successful endovascular aneurysm repair.Endoleak continues to be the major long-term complication of the endoluminal grafting technique,and the major cause for re-intervention.Life-long follow-up is extremely important.
