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.

This research aims to construct a lentiviral expression vector carrying the extracelluar domain (ED) of human hepatocyte growth factor receptor (C-Met), and to express it in transfected 293T cells. The extracellular domain of C-Met was amplified by RT-PCR, ligated with lentiviral expression vector p RRL-CMV-ED, and then expressed in 293T cell line. The expressed protein was purified and identified by RT-PCR and Western blot. The enzyme digestion and sequence analysis showed that the lentiviral expression vector p RRL-CMV-ED was constructed correctly. The size of amplified genes was about 2 700 bp. The purified protein with Ni-affinity column was about 105 kD analyzed by SDS-PAGE. The Western blot and ELISA results showed that the expressed protein which could bind to HGF specifically was the extracelluar domain of human hepatocyte growth factor receptor. This research may lay a foundation for further study of anti-C-MET monoclonal antibody and neutralizing antibody.

This study is to investigate the inhibitory effect of kaempferol on inflammatory response of lipopolysaccharide(LPS)-stimulated HMC-1 mast cells. The cytotoxicity of kaempferol to HMC-1 mast cells were analyzed by using MTT assay and then the administration concentrations of kaempferol were established. Histamine, IL-6, IL-8, IL-1β and TNF-α were measured using ELISA assay in activated HMC-1 mast cells after incubation with various concentrations of kaempferol (10, 20 and 40 µmol.L-1). Western blot was used to test the protein expression of p-IKKβ, IκBα, p-IκBα and nucleus NF-κB of LPS-induced HMC-1 mast cells after incubation with different concentrations of kaempferol. The optimal concentrations of kaempferol were defined as the range from 5 µmol.L-1 to 40 µmol.L-1. Kaempferol significantly decreased the release of histamine, IL-6, IL-8, IL-1β and TNF-α of activated HMC-1 mast cells (P<0.01). After incubation with kaempferol, the protein expression of p-IKKβ, p-IKBa and nucleus NF-κB (p65) markedly reduced in LPS-stimulated HMC-1 mast cells (P<0.01). Taken together, we concluded that kaempferol markedly inhibit mast cell-mediated inflammatory response. At the same time, kaempferol can inhibit the activation of IKKβ, block the phosphorylation of IκBα, prevent NF-KB entering into the nucleus, and then decrease the release of inflammatory mediators.

Objective To investigate the effects of the low-osmolar nonionic contrast media on renal function in elderly patients suffering from ischemic cerebral vascular disease and undergoing angiography.To study the incidence and risk factors for contrast-induced nephropathy (CIN).Methods 276 elderly patients who were going to receive selective cranial angiography and bilateral renal angiography were included.The 0.9 ％ sodium chloride (1 ml · kg-1 · h-1) was administered in all patients 6 hours before and 12 hours after contrast media administration.No patients suffered from obviously congestive heart failure.The levels of serum creatinine (Scr) and serum urea nitrogen (SUN) were measured 3 days before and at day 1,2,6 after the administration of contrast media respectively.Then creatinine clearance rate (Ccr) was calculated.Multivariate predictors of contrastinduced nephropathy were determined by logistic regression.Results Among the 276 patients,CIN occurred in 19 patients (6.9％),among whom 4 patients suffered from severe renal artery stenosis and received percutaneous transluminal renal angioplasty (PTRA) at 1 week after undergoing angiography.The renal function in the other 15 cases with CIN were recovered to baseline 1evel 3 months after the use of contrast media.No patients underwent a maintenance hemodialysis.In the 19 patients with CIN,the levels of SUN and Scr were higher and Ccr was lower at day 1 and 2 after angiography than before the procedure (all P ＜ 0.05),but the parameters were decreased to preoperative level at day 6 after angiography (all P＞0.05).Logistic regression analysis showed that renal dysfunction,diabetes mellitus and severe renal artery stenosis were the major risk factors for contrast-induced nephropathy.Conclusions Low-osmoiar nonionic contrast used in angiography is safe for elderly patients if adequately hydrated with 0.9 ％ sodium chloride.The clinical risk factors for CIN are renal dysfunction,diabetes mellitus and severe renal artery stenosis.

Objective To investigate the prevalence and risk factors of atherosclerotic renal artery stenosis (ARAS) in patients with ischemic stroke (IS).Methods A total of 596 consecutive patients with ischemic stroke underwent cerebrovascular and renal angiography at our hospital from January 2008 to March 2013.Renal artery stenosis was defined as at least one of renal artery narrowing ≥ 50％ of luminal diameter.Multivariate logistic regression analysis was performed to investigate the association of the clinical variables with ARAS.Results Intracranial arterial stenosis (ICAS) was identified in 203 patients (34.1％),including 108 cases (18.5％) with arteriostenosis ≥ 50％.Extracranial arterial stenosis (ECAS) was identified in 250 patients (41.9％),including 149 cases (25.0％) with arteriostenosis ≥ 50％.The prevalence of ECAS was higher than that of ICAS(x2 =7.86,P ＜ 0.05).ARAS was identified in 77 patients (12.9％),and the prevalence of ARAS in patients with ECAS ≥50％ was higher than that in with ICAS ≥50％ (30.2 ％ vs.18.5％,x2 =4.52,P ＜0.05).Multivariate analysis showed that the age≥ 60 y (OR:2.48,P ＜ 0.05) and ECAS ≥ 50％ (OR:5.37,P ＜ 0.05) were independent risk factors for prevalence of ARAS.Conclusion ARAS is a relatively common finding among patients with ischemic stroke,suggesting that renal angiography should be performed in elderly IS patients,especially for those combined with severe ECAS.

Objective To investigate the effects of total flavonoids in Gingko Biloba on glucose and lipid metabolism and liver function in rats with insulin resistance. Methods Forty SD rats were randomly divided into normal control group,model group,total flavonoids in Gingko Biloba group and rosiglitazone group(positive drug control group)(n=10).Models of insulin resistance were established by high glucose and high fat diet in model group,total flavonoids in Gingko Biloba group and rosiglitazone group.After treatment for 12 weeks,serum glucose,serum lipids,and parameters of insulin resistance,liver function and anti-oxidation capability were detected in each group,and histologic observations of liver tissues were conducted with adipose staining. Results The serum glucose,insulin resistance index(HOMA-IR),insulin action index(IAI),serum total cholesterol(TC),triglyceride(TG),liver malondialdehyde(MDA) and serum transaminase activity in total flavonoids in Gingko Biloba group were significantly lower than those in model group(P
