    Abstract Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases and its prevalence is increasing worldwide. It is reported that NAFLD is associated with colorectal polyps. Since identifying NAFLD in its early stages could prevent possible disease progression to cirrhosis and decrease the risk of HCC by early intervention, patients with colorectal polyp may thus be considered a target group for screening NAFLD. This study aimed to investigate the potential of serum microRNAs (miRNAs) in identifying NAFLD for colorectal polyp patients. Serum samples were collected from 141 colorectal polyp patients, of which 38 had NAFLD. The serum level of eight miRNAs was determined by quantitative PCR and delta Ct values of different miRNA pairs which were compared between NAFLD and control groups. A miRNA panel was formulated from candidate miRNA pairs by multiple linear regression model and ROC analysis was performed to evaluate its diagnostic potential for NAFLD. Compared to the control group, the NAFLD group showed significantly lower delta Ct values of miR-18a/miR-16 (6.141 vs. 7.374,

    Abstract This study investigates the feasibility of using biodegradable secondary alcohol ethoxylate (SAE) non-ionic surfactant as a building block for the formation of reverse micelles, functioning as reactive dye carriers for the dyeing of cotton fabric in non-aqueous octane medium. Ten dyeing parameters were optimised, by a one-factor-at-a-time approach, namely: (i) effect of colour fixation agent; (ii) surfactant-to-water mole ratio; (iii) surfactant-to-co-surfactant mole ratio; (iv) volume of soda ash; (v) volume of dye; (vi) solvent-to-cotton ratio; (vii) dyeing temperature; (viii) dyeing time; (ix) fixation time; (x) soda-ash-to-cotton ratio. The colour properties, fastness properties and physical properties of SAE-dyed samples were experimentally compared with the conventional water-dyed samples. The optimised condition was found when SAE samples were dyed as follows: (a) 1:20 surfactant-to-water ratio; (b) 1:8 surfactant-to-co-surfactant ratio; (c) 10:1 solvent ratio; (d) 40 min dyeing time; (e) 60 min fixation time; and (f) 70 °C dyeing and fixation temperature. The results showed that SAE-dyed samples have better colour strength, lower reflectance percentage and comparable levelness, fastness and physical properties than that of water-dyed samples. SEM images revealed that the dyed cotton fibres had no severe surface damage caused by an SAE-based reverse micellar dyeing system. The TEM image depicts that the reverse micelle was of nanoscale, spherical-shaped and had a core-shell structure, validating the presence of reverse micelle as a reactive dye carrier and the potential of an SAE-based reverse micellar system for dyeing of cotton fabrics.

    Abstract Background: Peritoneal dialysis (PD) patients with impaired hand-eye function require helper assistance. Our centre developed a connection device that assists patients with impaired hand-eye function to perform PD exchange themselves, but the clinical outcomes in these patients have not been investigated.
    Methods: We retrospectively reviewed patients who had device-assisted continuous ambulatory peritoneal dialysis (CAPD) during 2007-2016 and compared their clinical outcomes with age- and sex-matched patients receiving helper-assisted CAPD.
    Results: One hundred seventy-two patients (86 each in the device- and helper-assisted CAPD groups) were followed for 29.9 (19.4-43.3) months. The device- and helper-assisted groups had comparable peritonitis rates (0.489 and 0.504 episode per patient-year, respectively,
    Conclusion: Device-assisted CAPD confers comparable outcomes as helper-assisted CAPD and is a viable option in PD patients with impaired hand-eye function.

    Abstract Background: With the increasing availability of the surgical robotic system, the young generation colorectal surgeons may learn robotic-assisted rectal surgery upfront. There are currently very limited studies evaluating the learning curve of novice rectal surgeons.
    Objective: This study aimed to evaluate the learning curve of a surgeon who had limited experience in open and laparoscopic rectal surgery.
    Methods: Thirty-nine consecutive robotic-assisted total mesorectal excisions were performed from March 2013 to October 2014. All cases were performed by a single surgeon whose prior experience in open or laparoscopic low rectal cancer resections was <5 cases. The learning curve was analyzed using the cumulative sum method.
    Results: Thirty-four low anterior resections, four abdomino-perineal resections, and one Hartmann's operation were performed. The mean total operating time was 397.2 ± 184.3 min. There was no conversion. The major complication rate was 10.3 %. When total operating time was analyzed with the CUSUM method, three phases could be identified. They are the initial eight cases, middle 17 cases, and the final 14 cases. The first phase consisted of more proximal tumors (86.3 ± 20.7 vs. 58.0 ± 34.9 mm from anal verge, p = 0.04) and was associated with a shorter total operating time (243.5 ± 38.0 vs. 540.9 ± 133.4 min, p = 0.000) and less estimated blood loss (81.3 ± 25.9 vs. 168.8 ± 99.5 ml, p = 0.02) compared to the second phase. When the third phase is compared with the first and second phase, it has shorter total operating time (310.6 ± 164.5 vs. 44 5.7 ± 179.8 min, p = 0.03). Complications rate were 12.5, 17.6, and 0 % for phase one, two, and three respectively.
    Conclusions: In this study, the learning curve for a novice rectal surgeon was 25 cases. This is comparable to those who have already mastered the technique with laparoscopic or open approach. Surgical robotic system may have a role in shortening the learning curve for low rectal resection.
