AIM: To retrospectively analyze the effect of different surgical treatment on intraocular foreign bodies, according to different types and position.
METHODS: Clinical data of 46 cases diagnosed with intraocular foreign bodies from June 2010 to April 2013 were retrospectively analyzed.
RESULTS:Intraocular foreign bodies in anterior segment could be removed or magnetically attracted directly, intraocular foreign bodies in posterior segment could be attracted if there was accurate location. Vitrectomis was more favorable for the non magnetic or intraocular foreign bodies in posterior segment. In 46 cases, all intraocular foreign bodies ( 100%) in posterior segment were removed successfully. Among them the functional cure in 33 cases ( 72%) , the anatomical cure in 12 cases ( 26%) , discharged in 1 case (2%).
CONCLUSION:The aim of operation is to reconstruct of eyeball structure preserve and restore visual function. We should find more appropriate mode of operation and timing of surgery according to the foreign bodies'different types and injury of eyeball, reduce complications, preservation eyeball and improve visual function.

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.

AIM: To compare the clinical outcomes of pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells to treat and prevent the recurrence of pterygium.METHODS: Fifty patients (60 eyes) were divided into 2groups, and pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells (group A) and pterygium excision followed by transplantation of conjunctiva autograft harvested from counter-side limbus with stem cells (group B) were performed respectively.The surgical time of each case was recorded.RESULTS: All the 50 cases (60 eyes) of pterygium were recruited. The epithelization of cornea and conjunctiva in all cases finished in 2-5d, During the follow-up of 6-12mo, pterygium reoccurred in 2 cases (1 in each group), with no difference in recurrence rate. The mean surgical time was 25± 8min for group A,43± 11min for group B, the difference being statistically significant (P＜0.05, t-test).CONCLUSION: Both methods, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells are effective on treating and reducing the recurrence of pterygium. Compared with the latter, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells is simpler and easier to perform, and is preferred by the patients too.

Objective To explor the value of Tei index for evaluation the cardiac function of patients with chronic heart failure(CHF).Methods Tei index in 60 patients with CHF(CHF group) and 30 normal controls(control group) were evaluated and compared with the levels of NT-ProBNP and the NYHA class,and the sensitivity and specificity of Tei index for CHF diagnosis were appraised.Results (1) Tei index in CHF group was significantly higher than that in control group.When Tei index was more than and equal to 0.45,the sensitivity,specificity,positive predictive value,and negative predictive value of Tei index for diagnosing CHF were 85.6％,90.4％,89.8％ and 78.0％.(2)There was a remarkable positive correlation between Tei and Log NT-ProBNP(r =0.84,P ＜ 0.01).(3)There were significant differences in Tei index among NYHA Ⅱ,Ⅲ,Ⅳ class [(0.47 ± 0.06),(0.56 ± 0.08),(0.64 ±0.13)].Conclusion Tei index can be used to diagnose CHF and evaluate the degree of it.

Objective:To research the number and function of monocyte-macrophages in patients with chronic active hepatitis B. Methods:The 51 chronic viral hepatitis B( CHB) patients were selected randomly,which consisted of 20 cases of mild-moderate,31 cases of severe group and 13 cases of healthy controls. PBMCs were separated by percoll. Monocytes were tagged by CD14,the molecules CD80,CD86,HLA-DR and CD163 were detected by flow cytometry which expressed on the surface of PBMCs. Serum cytokine were detected for IL-10, IL-12 and IL-23 by ELISA. The distribution of CD68 was detected in the liver by immunohistochemical staining. Results:The expressions of CD80 for all chronic hepatitis B patients were lower than the controls respectively,no matter mild-moderate or even severe group. Similarly,the HBV patients expressed lower level of CD86 in the peripheral blood mononuclear cells when compared with the control group. Furthermore, there was statistically difference between the levels of CD86 in severe group compared with control group (P<0. 01). As the expression of CD80 and CD86,the levels of HLA-DR in the patents had also declined when compared with controls. While the HLA-DR levels in both the mild-moderate HBV hepatitis groups were statistically significant higher than the severe group (P<0. 01). Different from the above all,the expression of CD163 in all chronic HBV hepatitis was higher than the control group. The CD68 positive cells in chronic HBV patients were observed and infiltrated increasingly in portal area and hepatic lobules (P<0. 05). There were statistically significant differences of IL-10 levels between the mild-moderate group,severe group and the control group,respectively (P<0. 01). Conclusion:Macrophages have participated in the pathological lesions of liver in CHB patients,among peripheral blood mononuclear cells,the phenomena of imbalance between type M1/M2 and polarization to type M2 have been observed,which participated in the development of the chronicity of CHB.

Objective To evaluate the causes,prevention and treatment ot laparoscopic comphca- tions in urologic surgery.Methods From May 2000 to May 2004,135 urologic laparoscopies were per- formed,including 17 transperitoneal laparoscopies and 118 retroperitoneal laparoscopies.Of the135 cases,26 had adrenal adenoma extirpation;31 had roof-removal and decompression of renal cyst;25 had radical ne- phrectomy;6 had pyeloplasty;2 had partial resection of renal capsula and encapsulation of the great omen- tum;2 had partial nephrectomy;4 had pelviureteral resection;13 had ligation of renal pedicle lymphatic ves- sel;2 had ureterolysis;7 had ureterolithotomy;12 had ligation of spermophlebectasis;5 had exploration,re- duction and fixation of undescended testis.The intra-and post-operative complications were retrospectively reviewed and clinically analyzed.Results Overall,14 cases(10.4%)had complications.Intraoperative complications occurred in 10 cases,including 6 cases of peritoneal injuries,which were clamped during oper- ation;4 of vascular injuries,which resulted in conversion to open surgery.Postoperative complications oc- curred in 4 cases,including 2 of subcutaneous emphysema,which was spontaneously absorbed at 5 and 7 d after operation;1 of incision seepage,which was drained for 40 d and then disappeared;and 1 of urine reten- tion,for which urethral catheterization was kept for 3 d and then the patient had voluntary voiding.No death occurred in this series.Conclusions Understanding the characteristics of laparoscopic complications in u- rologic surgery and systematic training of the surgeons can reduce the occurrence of complications.

AIM:To investigate protective effects of novel extract of Ginkgo biloba(nGBE) in different administration modes on glutamate-induced neuronal damage.METHODS: The values of Essential nGBE were obtained by supercritical CO_2 fluid extraction.Based on glutamate excitotoxicity of primary cultures from neonatal Wistar rats hippocampal,by use of Trypan blue dye staining,testing the lactate dehydrogenase leakage from cultured neurons and terminal deoxynucleotidyl transferase-mediated nick end labeling(TUNEL) method,we examined glutamate-induced necrosis and apoptosis.The protective effects of nGBE in different administration modes(pre-treatment and post-treatment) were adopted and compared with the NMDA receptor uncompetitive antagonist MK-801 in acute-treatment.RESULTS:Treatment with nGBE in two administration modes all could increase ratio of surviving neuron,decrease LDH efflux and reduce ratio of neuron apoptosis in different degree,and the benefit of pre-treatment was superior to post-treatment,but inferior to MK-801.CONCLUSION:The extracts of Ginkgo biloba used nowadays in cerebrovascular disease as post-treatment have no prominent effect as far as their mechanism of antiexcitotoxicity.However they may have more value if they were used for precautionary intervention in high-risk population.

Objective To explore the clinical effect of modified frontalis muscle suspension for severe blepharoptosis correction. Design Retrospective case series. Participants Fifty-six cases (101 eyes) with severe blepharoptosis. Methods Modified frontalis mus- cle suspension was adopted. The technique included single blepharoplasty-type incision, dissecting the posterior gaps of frontalis muscu- lar fasciae ahead,then euthyphoria isolating anterior gaps of rontalis muscular fasciae, using frontalis muscle transfer without vertical incision. Main Outcome Measure The positon chang of the upper eyelid in the primary position gaze. Results The follow-up period ranged from 8 to 20 months (mean, 13.6 months). All the patients were deemed to have a good surgical outcome. Complications such as ectropion and corneal exposure were avoided. But ten eyes required reoperation for undercorrection, six eyes for overcorrection and two eyes for entropion. Conclusion This surgical technique is a useful procedure that results in substantial cosmetic and functional im- provement with few complications.

Objective To explore the serum level of Glucagon like peptide-1 in late-onset Alzheimer′s patients and its clinical significance.Methods Case control study.Collecting cerebral vascular disease fifty-five cases, diagnosed with late-onset Alzheimer′s disease sixty-one cases, type 2 diabetes mellitus fifty-one cases , type 2 diabetic patients combined with late-onset Alzheimer′s disease thirty-seven patients from the Shanghai East Hospital and partly Pudong area elderdly hospital during October 2013 to March 2014, and forty healthy persons as normal control from physical examination center of Shanghai East Hospital during September 2013 to February 2014.Measuring the concentrations of GLP-1,β-amyloid, Tau protein and other routinely used clinical tests in the serum of patients from the normal controls , cerebrovascular disease , late-onset Alzheimer′s disease, type 2 diabetes and type 2 diabetes mellitus combined with late-onset Alzheimer′s disease by ELISA method developed in our laboratory.The blood samples were also collected at three fixed time including fasting time ,1 hour after taking glucose , 2 hour after taking glucose, the concentrations of GLP-1 were determined in the LOAD group , T2DM group and the T2DM combined with LOAD group and normal control group.The concentrations of serum GLP-1 among groups were compared with single factor analysis of variance , and the concentrations of serum GLP-1 between the two groups were compared using LSD-t test.Analysing the correlation between GLP-1 and other indicators with Pearson analysis.Results The fasting GLP-1 levels of LOAD group were ( 123.4 ±20.8 ) nmol/L, and they were highest between the normal control group (78.6 ±6.0) nmol/L and the cerebral blood vessel disease group(89.0 ±8.7)nmol/L (F values were 3.46 and 1.98, P<0.05).The fasting GLP-1 levels of T2DM combined with LOAD group (157.9 ±28.6) nmol/L were higher than the LOAD group (123.4 ± 20.8) nmol/L (t =1.63,P <0.05), but there were no difference of the fasting GLP-1 levels between T2DM combined with LOAD group (157.9 ±28.6) nmol/L and T2DM group(153.8 ±18.0)nmol/L(t=0.96,P>0.05).Deficient secretion of GLP-1 after taking glucose 1 hour in most of the patients of T2DM combined with LOAD group (99.1 ±14.2) nmol/L, LOAD group(73.9 ±6.6 ) nmol/L and T2DM group (96.3 ±7.0 ) nmol/L could be concluded .The GLP-1 levels of T2DM combined with LOAD group after taking sugar 2 hour were (115.4 ±18.6)nmol/L ,and were higher than that of normal levels (63.3 ±6.2) nmol/L after taking sugar 2 hour(t=4.49,P<0.05).There were no difference between the GLP-1 levels of the LOAD group (73.6 ±5.8 )nmol/L and the GLP-1 levels of the normal group(63.3 ±6.2)nmol/L after taking sugar 2 hour (t=0.94,P>0.05).Pearson correlation analysis showed that the relationship of the levels of GLP-1 with Aβ( 1-42 ) and the levels of GLP-1 after taking glucose 1 h and 2 h were positively relative, and its coefficients of correlation were 0.401,0.436,0.722.Conclusions LOAD and T2MD are similar, and they have GLP-1 secretion shortage phenomenon after taking glucose , so monitoring dynamic change of GLP-1 after taking glucose may contribute to the auxiliary diagnosis of LOAD.
