| 3 | Profitability analysis of a femtosecond laser system for cataract surgery using a fuzzy logic approach显示文摘AIM:To define the financial and management conditions required to introduce a femtosecond laser system for cataract surgery in a clinic using a fuzzy logic approach.METHODS:In the simulation performed in the current study,the costs associated to the acquisition and use of a commercially available femtosecond laser platform for cataract surgery(VICTUS,TECHNOLAS Perfect Vision GmbH,Bausch & Lomb,Munich,Germany) during a period of 5y were considered.A sensitivity analysis was performed considering such costs and the countable amortization of the system during this 5y period.Furthermore,a fuzzy logic analysis was used to obtain an estimation of the money income associated to each femtosecond laser-assisted cataract surgery(G). RESULTS:According to the sensitivity analysis,the femtosecond laser system under evaluation can be profitable if 1400 cataract surgeries are performed per year and if each surgery can be invoiced more than $500.In contrast,the fuzzy logic analysis confirmed that the patient had to pay more per surgery,between $661.8 and $667.4 per surgery,without considering the cost of the intraocular lens(IOL).CONCLUSION:A profitability of femtosecond laser systems for cataract surgery can be obtained after a detailed financial analysis,especially in those centers with large volumes of patients.The cost of the surgery for patients should be adapted to the real flow of patients with the ability of paying a reasonable range of cost. | Jose Antonio Trigueros David P Pinero Mahmoud M Ismail | 2016 | International Journal of Ophthalmology(English edition)2016，9，7： | 1 |

| 11 | Screening the RFX6-DNA binding domain for potential genetic variants in patients with type 2 diabetes显示文摘BACKGROUND The regulatory factor X6 (RFX6), a member of regulatory factor X family, is known to play a key role in the development and differentiation of pancreatic beta cells as well as insulin production and secretion. However, the potential role of RFX6 in type 2 diabetes (T2D) is still unclear. AIM Recent studies have indicated that RFX6 binding to DNA could be disrupted in diabetes. Therefore, in this study we investigated whether genetic mutations are present in the DNA binding domain of RFX6 gene that could abrogate its function in T2D. METHODS A cohort of T2D patients was enrolled in this study, and the gene encoding the DNA binding domain of RFX6 was amplified by polymerase chain reaction and then analysed by direct DNA sequencing. RESULTS The DNA sequence analysis revealed the absence of any exonic mutation. However, we have identified a new heterozygous single nucleotide polymorphism (IVS6+31 C>T) in the intronic region of DNA binding domain gene that is present in 9.2% and 8.5% of diabetic and control people, respectively (P = 0.97).CONCLUSION We report the absence of any significant genetic variant that could affect the function of RFX6-DNA binding domain in T2D. | Ismail S Mahmoud Ayat Homsi Hamzeh J Al-Ameer Jihad Alzyoud Mais Darras Mohammad Al Shhab Malek Zihlif Ma’mon M Hatmal Walhan Alshaer | 2019 | World Journal of Diabetes2019，10，3： | 0 |
| 12 | Diffusion Monte Carlo calculations on LaB molecule显示文摘Potential energy curves for the lowest electronic states of LaB and LaB^- have been calculated by ab initio calculations.The diffusion Monte Carlo method has been employed in combination with three different trial functions. Spectroscopic constants have also been numerically derived for the neutral molecule and compared with the only available theoretical work;^([19]) however, predictions are provided for the corresponding constants for the anionic species which have not been reported yet. Our calculations suggest the high spin quintet state of LaB as the ground state with the triplet state higher in energy irrespective of the type of the functional used. This suggestion is in good accordance with the previous theoretical results calculated at B3LYP/LANL2DZ level of theory, whereas it contradicts with the prediction based upon B3LYP/SDD calculations in the same study. Moreover, variations of the permanent dipole moments as a function of the internuclear separations for the two electronic states of the neutral molecule have been studied and analyzed. | Nagat Elkahwagy Atif Ismail S M A Maizet K R Mahmoud | 2018 | Chinese Physics B2018，27，9： | 0 |
| 13 | Fibrin sealant for esophageal anastomosis:A phase II study显示文摘BACKGROUND Esophagectomy is a pivotal curative modality for localized esophageal or esophagogastric junction cancer(EC or EJC).Postoperative anastomotic leakage(AL)remains problematic.The use of fibrin sealant(FS)may improve the strength of esophageal anastomosis and reduce the incidence of AL.AIM To assess the efficacy and safety of applying FS to prevent AL in patients with EC or EJC.METHODS In this single-arm,phase II trial(Clinicaltrial.gov identifier:NCT03529266),we recruited patients aged 18-80 years with resectable EC or EJC clinically staged as T1-4aN0-3M0.An open or minimally invasive McKeown esophagectomy was performed with a circular stapled anastomosis.After performing the anastomosis,2.5 mL of porcine FS was applied circumferentially.The primary endpoint was the proportion of patients with AL within 3 mo.RESULTS From June 4,2018,to December 29,2018,57 patients were enrolled.At the data cutoff date(June 30,2019),three(5.3%)of the 57 patients had developed AL,including two(3.5%)with esophagogastric AL and one(1.8%)with gastric fistula.The incidence of anastomotic stricture and other major postoperative complications was 1.8%and 17.5%,respectively.The median time needed to resume oral feeding after operation was 8 d(Interquartile range:7.0-9.0 d).No adverse events related to FS were recorded.No deaths occurred within 90 d after surgery.CONCLUSION Perioperative sealing with porcine FS appears safe and may prevent AL after esophagectomy in patients with resectable EC or EJC.Further phase III studies are warranted. | Yao-Bin Lin Jian-Hua Fu Yan Huang Yi-Huai Hu Kong-Jia Luo Ke-Xi Wang AmosÉla Bella Dong-Rong Situ Ji-Yang Chen Ting Lin Xavier B D’Journo Nuria M Novoa Alessandro Brunelli Hiran C Fernando Robert J Cerfolio Mahmoud Ismail Hong Yang 无 | 2020 | World Journal of Gastrointestinal Oncology2020，12，6： | 0 |
