ABSTRACT
@#【Objective】Fibroscan has been recommended by multiple clinical guidelines as the first choice among the non-invasive tools for evaluating hepatic steatosis and liver stiffness. The study herein assessed the factors related to the success rate and reliability of the measurement.【Methods】A total of 788 volunteers from Year 2018′ s staff physical checkup in The First Affiliated Hospital of Sun Yat- sen University were recruited. Relationship between age ，gender， body mass index ，waist circumference of the subjects ，and the operator′s experience ，and their effect on success rate and reliability were analyzed.【Results】had a higher detection rate for fatty liver as compared with ultrasound（55.9% vs.39.9% ，P<0.001）. Detection failure and unreliable measurements occurred in only 1.4% of all the participants. Success rate was not associated with gender ，but decreased significantly with increased age ，body mass index and waist circumference （P<0.05）. LSM IQR/Median increased accordingly ，thus reduced the reliability of the measurement. With accumulated number of measurements by the same operator，so did the success rate and reliability of the results. An operator with more than 300 measurements could be deemed as experienced operator.【Conclusions】The success rate and reliability of the measurement was affected by increased age ，body mass index ，waist circumference and operator′ s experience. Fixed operator could also achieve very high success rate and reliable measurement using Fibroscan after short- term training.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the safety and efficacy of the transabdominal-hiatal approach of radical gastrectomy for the advanced proximal gastric cancer.</p><p><b>METHODS</b>The clinical data of 40 advanced proximal gastric cancer patients with involvement of distal esophagus admitted in Tongcheng People's Hospital from June 2003 to September 2006 were analyzed retrospectively. Patients included 27 men and 13 women with a mean age of 56.1 years (range: 37 to 76 years). The data were compared with those of 40 proximal gastric cancer patients undergoing standard thoracoabdominal approach (control group) during the same period.</p><p><b>RESULTS</b>As compared with the control group, the transabdominal-hiatal approach showed less blood loss [(181.3 ± 63.7) ml vs.(248.8 ± 79.7) ml], shorter operating time [(4.1 ± 0.6) h vs. (5.3 ± 0.7) h], shorter ICU stay [(6.5 ± 5.7) d vs. (19.4 ± 18.0) d] and shorter postoperative hospital stay [(14.0 ± 2.3) d vs.(18.7 ± 3.0) d] (all P<0.05). The complication rates of transabdominal-hiatal approach group and thoracoabdominal approach group were 7.5% (3/40) and 10.0% (4/40), and the 5-year survival rates were 51.3% and 60.0%, respectively (both P>0.05).</p><p><b>CONCLUSION</b>The transabdominal-hiatal approach of radical gastrectomy for proximal gastric cancer is safe and effective, which may substitute the standard thoracoabdominal technique.</p>

The yeast Sacchromyces cerevisiae is most widely used for producing bioethanol in alcoholic industry due to its higher ethanol yield and fermentation rate. However, the toxic effect of accumulated ethanol is one of the main factors, which limit high ethanol production. Thus, investigating the mechanisms of yeast ethanol tolerance will provide the basis for solving the industrial problem. This article reviewed the mechanisms of Sacchromyces cerevisiae ethanol tolerance focusing on its cell physiological behaviors, structure and biochemical composition, as well as its genetic basis.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate corneal refractive changes after scleral buckling surgery.</p><p><b>METHODS</b>In a prospective self-controlled clinical study, we investigated the changes of refractive power, astigmatic power, astigmatic axis, and irregular astigmatic power of anterior corneal surface following scleral buckling surgery for retinal detachment in 30 patients (30 eyes). The corneal shapes were detected by Orbscan II topography at 1 day before surgery, and 1 week, 1 month, and 3 months after surgery. The effects of some surgical factors on the anterior corneal refractive changes were analyzed.</p><p><b>RESULTS</b>After surgery, refractive power on corneal anterior surface decreased significantly in peripheral zone at 1 week (P < 0.01). Astigmatic power increased obviously in central zone. The direction of astigmatic axis matched the direction of the buckle, and changed obviously in central zone after 1 week (P < 0.05). Irregular astigmatic power did not change significantly. There was a significant correlation between the encircling length/the buckle width and the refractive changes of corneal anterior surface.</p><p><b>CONCLUSION</b>Refractive changes of corneal anterior surface following scleral buckling surgery was mainly temporary. Changes in the shape of corneal should be minimized to ensure a favorable postoperative visual acuity.</p>

Twelve cases of Bartter's syndrome were reported and reviewed retrospectively.Usually vomiting was the first sympton in children,while fatigue was common in adults.Bartter's syndrome was characteristic of hypokalemia,metabolic alkalosis,elevations of plasma renin activity,serum angiotersinⅡand aldosterone and juxtaglomerular apperatus hyperplasia.Supplementation of potassium choloride was the main manner of therapy.
