ABSTRACT
Chronic diabetic wound remains a critical challenge suffering from the complicated negative microenvironments, such as high-glucose, excessive reactive oxygen species (ROS), hypoxia and malnutrition. Unfortunately, few strategies have been developed to ameliorate the multiple microenvironments simultaneously. In this study, Chlorella sp. (Chlorella) hydrogels were prepared against diabetic wounds. In vitro experiments demonstrated that living Chlorella could produce dissolved oxygen by photosynthesis, actively consume glucose and deplete ROS with the inherent antioxidants, during the daytime. At night, Chlorella was inactivated in situ by chlorine dioxide with human-body harmless concentration to utilize its abundant contents. It was verified in vitro that the inactivated-Chlorella could supply nutrition, relieve inflammation and terminate the oxygen-consumption of Chlorella-respiration. The advantages of living Chlorella and its contents were integrated ingeniously. The abovementioned functions were proven to accelerate cell proliferation, migration and angiogenesis in vitro. Then, streptozotocin-induced diabetic mice were employed for further validation. The in vivo outcomes confirmed that Chlorella could ameliorate the undesirable microenvironments, including hypoxia, high-glucose, excessive-ROS and chronic inflammation, thereby synergistically promoting tissue regeneration. Given the results above, Chlorella is considered as a tailor-made therapeutic strategy for diabetic wound healing.

ABSTRACT
Objective To evaluate the efficacy and safety of submucosal injection using endoscopic water-jet in peroral endoscopic myotomy (POEM) for treatment of patients with achalasia of cardia (AC). Methods A retrospective analysis was performed on the data of 126 AC patients undergoing POEM in PLA General Hospital from March 2013 to February 2016. All the 126 patients were divided into two groups, 73 in the water-jet group and 53 in the needle injection group. The time to creating a submucosal tunnel, entire operation time, and incidence of complications were compared between the two groups. Results The time to creating a submucosal tunnel and the entire operation time of the water-jet group were both significantly less than those of the needle injection group (6. 38±0. 94 min VS 13. 81±1. 13 min, P<0. 05;27. 81±5. 76 min VS 70. 25±22. 67 min, P<0. 05). The hospital stay of patients after operation was less in the water-jet group than that in the needle injection group (4. 38±1. 87 days VS 5. 64±1. 83 days, P<0. 05). The incidence of bleeding [5. 5％ (4/73) VS 17. 0％ (9/53), P<0. 05] and fever [12. 3％ (9/73) VS 26. 4％ (14/53), P<0. 05] were lower in the water-jet group than those in the needle injection group. The incidences of perforation and pectoralgia were not significantly different between the two groups ( both P>0. 05 ) . Conclusion Endoscopic water-jet injection is safe and effective in POEM, which effectively shortens the time to creat a submucosal tunnel and the operation time, and reduces the incidences of complications including bleeding and fever.
ABSTRACT
Objective To evaluate the clinical efficacy of pre-procedure simethicone on detection of pharynx by upper gastrointestinal endoscopy. Methods A total of 100 patients with esophageal squamous cell carcinomas ( ESCCs) were enrolled in this prospective controlled trial and randomly assigned into two groups. The study group was given gargle with 5 mL simethicone plus 5 mL water combined with conventional procedure before gastroscopy. The control group was prepared according to the conventional procedure. The age, gender, tumor stage, lesion size, doctor＇s satisfaction and examination time between two groups were analyzed. Results The basic conditions between the two groups, including age, gender, and tumor stage were not significantly different (all P＞0. 05). The detection rate of superficial lesion in pharynx was higher in the study group than that in the control group, with no significant difference [8. 16%(4/49) VS 2. 04%( 1/49), P＝0. 362]. The median time of pharyngeal observation in the study group was less than that in the control group (21. 7 s VS 33. 9 s, P＝0. 000). The doctor was more satisfied in the study group than the control group (P＝0. 001). Conclusion Pre-procedure with simethicone improves the endoscopic visibility and detection rate of superficial squamous cell carcinoma with less observation time.
ABSTRACT
A fluorescence nanosensor based on an easily prepared fluorescent molecule, 1-oxo-1H-phenalene-2,3-dicarbonitrile (OPD), was developed for highly sensitive detection of glucose.Under the catalysis of horseradish peroxidase (HRP), 3,3′,5,5′-tetramethylbenzidine (TMB) was oxidized into oxidized TMB (oxTMB) by H2O2.And the fluorescence of OPD was quenched by the intense absorption of the formed oxTMB, thus realizing effective quantitative detection of H2O2.The linear range was 0.05-0.8 μmol/L and 1-10 μmol/L respectively, with limit of detection of 0.02 μmol/L.Besides, on the basis of transformation of glucose into H2O2 through the catalysis of glucose oxidase, this nanosensor could be further exploited for highly sensitive detection of glucose.The TMB-HRP-OPD sensor exhibited linear range of 0.1-3.0 μmol/L and 4.0-30 μmol/L respectively for detection of glucose, with limit of detection of 0.02 μmol/L.Furthermore, it was successfully applied to the determination of glucose in real human serum and the results were in good agreement with the clinical data.

Compared with 8-day subgroup, the cells in Calcification+3-MA group presented increased calcium deposition, decreased lfuorescence distribution of LC3 II and more cells with positive Runx2 protein expression, all P<0.05. Conclusion: Autophagy has the protective effect on process of phosphate induced VSMC calciifcation in experimental rats.
ABSTRACT
Objective To analyze the miss rates of colorectal adenomas during colonoscopy as well as risk factors influencing the adenoma miss rates and to take corresponding measures. Methods A total of 432 patients who underwent index and follow-up colonoscopy in 18 months were randomized and investigated. The results of two colonoscopies were compared and the missed adenomas were defined as the adenomas de-tected only during the second colonoscopy. Miss rates were calculated according to patient-based methods. Chi-square test was used to analyze the relative factors influencing the adenoma miss rate of per-patient. Then the meaningful factors were chosen into the logistic regression model for multiple factors analysis. Results Of 432 patients,116(26. 9%)had missed adenomas on first colonoscopy. Single factor analysis found that the size of adenoma( χ2 = 89. 686,P = 0. 000),the shape of adenoma( χ2 = 68. 488,P = 0. 000),the location of adenoma(χ2 = 77. 055,P = 0. 000)and adenoma tissue types(χ2 = 417. 000,P = 0. 000)were the risk factors for miss rates of colorectal adenomas. Number of polyps(χ2 = 8. 450,P= 0. 038),the organi-zation type of polyp(χ2 = 10. 718,P= 0. 013)and proficiency of colonoscopists(χ2 = 56. 069,P= 0. 000), the quality of bowel preparation(χ2 = 39. 195,P = 0. 000),insertion time(χ2 = 13. 133,P = 0. 001)were also the risk factors for miss rates of colorectal adenomas. Logistic regression analysis showed that the bigger the adenoma size,the less missed adenomas(OR= 0. 341,95%CI:0. 173-0. 671). Also,the longer insertion time took,the lower the adenoma miss rate(OR = 0. 987,95% CI:0. 981-0. 994). Per-patient miss rates were lower for high-risk adenomas compared with low-risk adenomas(OR = 0. 324,95%CI:0. 154-0. 680). Adenomas happening in multiple parts of bowel easily leads to missing(OR= 3. 791,95%CI:1. 505-9. 546). Conclusion The missed diagnosis of adenomas is not only significantly associated with features of missed adenomas,but also with skills of colonoscopists,insertion time,and bowel preparation. The key is high-quality index colonoscopy to avoid adenomas missing.
