BACKGROUND: Some patients with chronic pancreatitis (CP) may require surgery mainly because of intractable pain, suspicion of malignancy, or complications related to CP. This study aimed to analyze the efficacy of surgical treatment for patients with CP in terms of pain relief, control of local complications, and pancreatic endocrine/exocrine function. METHODS: Twenty-six patients with CP were treated surgically at our hospital from June 1985 to November 2005. The clinical data of these patients were analyzed retrospectively. RESULTS: The follow-up time ranged from 8 to 130 months with a median of 60.6 months. No patients were lost to follow-up. All patients had improvement of clinical symptoms such as abdominal pain, steatorrhea and weight loss, to some degree, especially pain relief in patients with good dilation and high pressure of the main pancreatic duct. The endocrine and exocrine functions were not alleviated in all patients, otherwise the impaired glucose tolerance was improved in 8 (30.8%), 15 (57.7%) maintained the same body weight, one (3.8%) had an acute attack of CP, and 2 (7.7%) developed pancreatic carcinoma in the 16th and 28th month postoperatively and died within 3 years after operation for CP. The 1-, 3-, 5-year pain-free rates of CP patients were 96.2% (25/26), 88.5% (23/26) and 84.6% (22/26), respectively. CONCLUSIONS: In selected patients with CP, surgical treatment is a safe procedure and can effectively relieve pain and control local complications; also, it is helpful to improve the quality of life for patients with pancreatitis, and to control the development of this disease.

Magnesium alloys,known for their exceptional lightweight properties,have presented challenges in various applications due to their limited corrosion *** this study,the corrosion resistance of Mg_(97)Zn_(1)Y_(2)magnesium alloys was enhanced by incorporating Zr elements into the Mg_(97)Zn_(1)Y_(2)matrix,which is distinguished by long periodic stacking ordered(LPSO)*** show that Mg_(97)Zn_(1)Y_(2)-xwt.%Zr(x=0,0.1,0.3,0.6)alloys containing Zr exhibit reduced hydrogen evolution rates and decreased corrosion levels compared with that without Zr,when immersed in a 3.5wt.%NaCl *** of 0.3wt.%Zr results in the most significant improvement,with a corrosion rate as low as 2.261 mL·cm^(-2),representing an 86%reduction from 16.438 mL·cm^(-2)of the base ***,alloys with Zr additions demonstrate a more positive corrosion potential and lower corrosion current density than does the matrix alloy(64.92μA·cm^(-2)).The lowest corrosion current density,21.61μA·cm^(-2),occurs with the addition of 0.3wt.%*** introduction of Zr induces a change in the microstructure of the LPSO phases,increasing the charge transfer resistance within the alloy and thus effectively improving its corrosion resistance.

In this paper predecessors′achievements about the division between subtropical zone and warm temperate zone on the south slope of Funiu Mountain are firstly summarized, and the cause why these viewpoints about the division are different also has been presented. Seven soil profiles at different heights above sea level are dug along the south slope of Funiu Mountain. Many compositions and properties of soil humus have been analyzed in laboratory. A comprehensive study has been made about the division according to the compositions and properties of soil humus with mathematical method. During the analysis process eight indexes have been used, such as altitude, organic carbon, humic acid (HA), fulvic acid (FA), the ratio of humic acid and fulvic acid (HA/FA), two extinction coefficients (E4,E6), and their ratio (E4/E6).The result indicates that the boundary is at about 1000 meters above sea level.
