BACKGROUND: Special anatomical location makes eye lens expose to stressful situation in a long term. Whether the environmental stress can up-regulate the expression of heat shock proteins in human lens epithelial cells? Whether the synthesis increase occurs in the level of trenscdption or translation, remains unclear.OBJECTIVE: To observe the expression and location of heat shock protein 27 (HSP27) in human lens epithelial cells under the conditions of high temperature and oxidative stress, and to investigate the pathogenesis of the cataract.METHODS: Human lens epithelial cells cultured in vitro were exposed to heat (45 ℃) and oxidative stress (50 mmol/L H_2O_2) for 30 minutes, respectively, then allowed to recover normal conditions. At different intervals (0, 2, 4, 6, 16, 24 hours),immunocytochemistry and reverse transcription polymerase chain reaction were used to determine the expression and localization of HSP27.RESULTS AND CONCLUSION: HSP27 was shown to express in both physiological and stressful conditions. The expressions of HSP27 mRNA and protein ware remarkably increased at 2 hours following heat and oxidative stress, and reached the peak at 6 hours. HSP27 could maintain a high level for 16 hours. The stress-induced HSP27 protein positive particles transferred from the cytoplasm to the nucleus, and gradually shift back to the cytoplasm along time. It is proved that HSP27 exists in lens epithelial cells and can be increased after stress. The data suggested it may play an important protective role in lens epithelial cells in respond to cellular stress.

Background:Pancreatitis is the main complication of ERCP,and a variety of risk factors will increase its risk. Studies showed that temporary pancreatic duct stent can reduce the incidence of post-ERCP pancreatitis (PEP). Aims:To study the efficacy and safety of prophylactic pancreatic duct stenting on preventing PEP in patients with risk factors. Methods:Patients undergone ERCP and accompanied with one or more PEP-associated risk factors from November 2013 to November 2016 at Huaibei People's Hospital were enrolled,and were divided randomly into pancreatic duct stenting group (observation group)and non-stenting group (control group). Serum levels of amylase at 4,24 and 48 hours after the procedure and incidence of PEP were compared between the two groups. Results:A total of 297 patients were enrolled, and 147 patients were in observation group,and 150 patients in control group. No significant differences in gender,age and ERCP disease spectrum were found between the two groups (P > 0. 05). Incidence of PEP was significantly decreased in observation group than in control group (6. 1% vs. 16. 0%,P < 0. 05). Serum levels of amylase at 4,24 and 48 hours after the procedure were significantly decreased in observation group than in corresponding control group (P < 0. 05), however,no significant difference in incidence of hyperamylasemia was found between the two groups (59. 2% vs. 54. 7%, P > 0. 05). Conclusions:Prophylactic pancreatic duct stenting may decrease the incidence of PEP in patients accompanied with PEP-associated risk factors, especially could decrease the severity of PEP. However, the incidence of hyperamylasemia is not decreased.
