ObjectiveTo evaluate and compare the prognosis of idiopathic macular holes (IMH) and traumatic macular holes (TMH) treated by pars plana vitrectomy (PPV). Methods The clinical data of 72 IMH eyes and 55 TMH eyes, which were treated by PPV between November 2001 and December 2007,were retrospectively reviewed. The visual outcomes and macular anatomic closure were evaluated, and their relationships with prognostic factors including the size of macular hole (MH), preoperative visual acuity (VA) and duration of disease were analyzed. Results The closure rate of IMH (100. 0%) was significant higher than that of TMH (85.5%) (P=0. 001). The postoperative VA of IMH and TMH were (0. 25±0.02) and (0. 21±0. 21) respectively, both significantly increased compare to their preoperative VA (t=-6. 841, -4. 093; P=0.000). VA-increased IMH and TMH eyes had same VA (χ2=3. 651, P=0.07).Pre-PPV VA≥0. 1 IMH eyes had better outcomes than Pre-PPV VA<0. 1 IMH eyes (χ2 = 12.04, P=0. 001), while Pre-PPV VA had no effects on TMH outcomes (χ2=0. 371, P=0. 486). IMH eyes with small holes had better outcomes (t=2. 476, P=0. 016), and TMH eyes with small holes had better closure (t= -4. 042, P<0. 001). The duration of disease had no significant influence on TMH visual (χ2=0. 704,P = 0. 401 ) and anatomic (χ2 = 0. 166, P= 0. 684) outcomes. Conclusions PPV is an effective treatment for MH. The closure rate of IMH is higher than that of TMH. The diameter of MH and preoperative VA are major factors for IMH outcomes, and the duration of disease and preoperative VA have no effects on postoperative VA in TMH.

Background and purpose:Clinical data show that Endostar, a recombinant human endostatin, has the therapeutic beneift for patients with non-small cell lung cancer (NSCLC) while combined with chemotherapy or ra-diotherapy. However, the microenvironment changes induced by Endostar monotherapy in NSCLC is not yet clear. The purpose of this study was to prospectively study tumor vascular effects of Endostar monotherapy in patients with locally advanced or advanced NSCLC by dynamic contrast-enhanced perfusion computed tomography (CT perfusion, CT-p). Methods:Previously untreated patients with histologically or cytologically conifrmed locally advanced or advanced NSCLC were eligible. All patients received daily Endostar (7.5 mg?m2) for 14 days. CT-p scans were acquired at the baseline and post-treatment. CT-p parameters, such as blood lfow (BF), blood volume (BV) and permeability surface PS (area product), were measured in all patients.Results:Of all 7 patients enrolled, four were staged asⅢB and three as stageⅣ (2 with malignant pleural effusion, 1 with brain metastasis). The median BF, BV and PS values of baseline and post-treatment were 27.1/48.9 mL/100 mL/min, 86.8/84.8 mL/100 mL and 45.0/54.0 mL/100 mL/min, respectively. After administration of Endostar for 14 days , BF showed a signiifcant increase compared with that at baseline (P=0.028), whereas no signiifcant changes were found in BV (P=0.398) and PS (P=0.237) values.Conclusion:Our results suggest that Endostar monotherapy induces a signiifcant increase in BF whereas no signiifcant difference in BV and PS.

Background and purpose:We investigated whether lfuorine-18 lfuorodeoxyglucose (18F-FDG) maximal standard uptake value (SUVmax) of the primary tumor (SUV-T), SUVmax of the regional lymph nodes (SUV-N) or the overall loco-regional lesion SUVmax (SUV-TOTAL) was related to survival of patients with stage Ⅲ non-small cell lung cancer (NSCLC) who received Cetuximab and combined definitive chemoradiotherpay. Methods:From September 2009 to July 2012, seventeen patients with unresectable stageⅢNSCLC receiving cetuximab with cisplatin/vinorelbine (NP) followed by concomitant NP and intensity-modulated radiotherapy (IMRT) at the Fudan University Shanghai Cancer Center were enrolled onto a prospectively study. All patients received positron emission tomography/computerized tomography (PET/CT) scans within 2 weeks before enrolment. Univariate analysis were used to assess the correlation between SUV-T, SUV-N, SUV-TOTAL, gender, age, histology, tumour-node-metastasis (TNM) stage, performance status (PS) as well as smoking status and survival. The factors which showed statistical signiifcance entered into multivariate Cox-regression model. Survival functions of different populations were estimated by Kaplan-Meier method and compared by Log-rank test. Results:In the univariate analysis, SUV-T, SUV-N, SUV-TOTAL, PS and smoking status were prognostic factors. The best cut-off values for SUV-T, SUV-N and SUV-TOTAL were 11, 11 and 20, respectively. Multivariate analysis revealed that SUV-TOTAL (P=0.012), SUV-T (P=0.025), and SUV-N (P=0.033) were independent predictors of survival with hazard ratio (HR) of 14.7, 11.2, and 6.2, respectively. Conclusion:Local, regional and locoregional maximal SUVs deifned by 18F-FDG PET-CT scanning may have a strong correlation with survival in this patients setting, which merits further study.

Deciphering the metabolites of multiple components in herbal medicine has far-reaching significance for revealing pharmacodynamic ingredients.However,most chemical components of herbal medicine are secondary metabolites with low content whose in vivo metabolites are close to trace amounts,making it difficult to achieve comprehensive detection and identification.In this paper,an efficient strategy was proposed:herb-derived metabolites were predicted according to the structural characteristics and metabolic reactions of chemical constituents in Corydalis Rhizoma and chemical structure screening tables for metabolites were conducted.The fragmentation patterns were summarized from represen-tative standards combining with specific cleavage behaviors to deduce structures of metabolites.Ion abundance plays an important role in compound identification,and high ion abundance can improve identification accuracy.The types of metabolites in different biological samples were very similar,but their ion abundance might be different.Therefore,for trace metabolites in biological samples,we used the following two methods to process:metabolites of high dose herbal extract were analyzed to char-acterize those of clinical dose herbal extracts in the same biological samples;cross-mapping of different biological samples was applied to identify trace metabolites based on the fact that a metabolite has different ion abundance in different biological samples.Compared with not using this strategy,44 more metabolites of clinical dose herbal extract were detected.This study improved the depth,breadth,and accuracy of current methods for herb-derived metabolites characterization.

Objective To investigate the significance of serum adenosine deaminase level in type 1 diabe-tes patients(T1DM)with acute or chronic diabetes complications. Methods One hundred and eighty-four cases of type 1 diabetes patients were divided into three groups:T1DM without any complications(n = 55),T1DM with acute diabetes complications(n = 47)and T1DM with chronic diabetes complications(n = 82). We also enrolled 108 healthy persons as the control group.The clinical and biochemical data were collected and the influencing fac-tors of serum ADA were analyzed. Resultes(1)Serum ADA level of T1DM patients was higher than that of the healthy control people.T1DM patients with acute diabetes complications had lower serum ADA level compared with T1DM patients with chronic complications.(2)Results of Pearson correlations analysis showed that serum ADA level had positive correlation with fasting blood glucose.(3)Logistic regression analysis showed that the increase of serum ADA level was an independent risk factor in patients with chronic diabetes complications(OR:1.159,95% Cl:1.044~1.286),while it was a protective factor in patients with acute diabetes complications(OR:0.857,95% Cl:0.748~0.981). Conclusions High serum ADA level was observed in type 1 diabetes patients. The serum ADA level was an independent risk factor for T1DM patients with chronic diabetes complications,while it was a protective factor for T1DM patients with acute diabetes complications.
