To determine the rational layout parameters of the lateral high drainage roadway(LHDR) serving for two adjacent working faces, a mechanical model of the LHDR under mining influence was established, and the overburden fissure, mining-induced stress distribution rules were analyzed. First, the development characteristics of mining-induced overburden fissure and the stress distribution law of the upper section of the working face were analyzed. Second, by analyzing the distribution law of vertical stress at different layers, the lateral distance of the LHDR was determined as 25 m. Third, by analyzing the surrounding rock deformation effect, stress distribution law, and overburden fissure distribution law of the LHDR at the heights of 20, 25, and 30 m away from the roof, the rational horizon of the LHDR was determined to be 25 m. Finally, an example of a LHDR located 25 m above the roof of the No. 2 coal seam and 25 m away from the No. 2-603 working face was presented. Results show that when the No. 2-603 coalface is being mined, the surrounding rocks lag 80 m or even further and the working face tends to be stable. The relative deformations of the roof and floor of the roadway and both of its walls were 583 and 450 mm,respectively. The reduction rate of the roadway section was 21.52%–25.32%. The section of the roadway was sufficient to extract the pressure relief gas in the overburden of the No. 2-605 working face. The average gas concentration and the pure volume at the branch pipeline were 24.8% and 22.3 m^3/min,respectively, showing that the position of high-level boreholes was reasonable. 展开更多

AIM To retrospectively review patients with chronic pancreatitis(CP) treated with Frey's procedures between January 2009 and January 2014.METHODS A retrospective review was performed of patients with CP treated with Frey's procedures between January 2009 and January 2014 in the Department of Pancreatic Surgery. A cross-sectional study of postoperative pain relief, quality of life(Qo L), and alcohol and nicotine abuse was performed by clinical interview, letters and telephone interview in January 2016. Qo L of patients was evaluated with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30) version 3.0. The patients were requested to fill in the questionnaires by themselves via correspondence or clinical interview.RESULTS A total of 80 patients were enrolled for analysis, including 44 who underwent the original Frey's procedure and 36 who underwent a modified Frey's procedure. The mean age was 46 years in the original group and 48 years in the modified group. Thirtyfive male patients(80%) were in the original group and 33(92%) in the modified group. There were no differences in the operating time, blood loss, and postoperative morbidity and mortality between the two groups. The mean follow-up was 50.3 mo in the original group and 48.7 mo in the modified group. There were no differences in endocrine and exocrine function preservation between the two groups. The original Frey's procedure resulted in significantly betterpain relief, as shown by 5-year follow-up(P = 0.032), better emotional status(P = 0.047) and fewer fatigue symptoms(P = 0.028). When stratifying these patients by the M-ANNHEIM severity index, no impact was found on pain relief after the two types of surgery.CONCLUSION The original Frey's procedure is as safe as the modified procedure, but the former yields better pain relief. The severity of CP does not affect postoperative pain relief. 展开更多

Under the existed system, the capital structure is the basis of the corporate governance, the structure of the corporate governance is the reflection of the capital structure. The choice of the capital structure decides the level of the corporate governance to a great degree. This paper discusses the governance effect of Chinese public corporation in the view of capital structure. At last, the author suggests that the government should change the state of state-owned stock which takes a great proportion, make the state-owned stocks and corporation stocks enter and circulate in the market, develop investment banks, promote the stockholder's rights to circulate and recombine, enhance the supervision and the management of the stock markets, perfect the mechanism of the market's operation, set up the mechanism of the way to protect to pay back the debt, perfect the system of bankruptcy and develop the way of bond-financing, offset the drawbacks of the indirect-financing among banks and so on. All of the advice was given to perfect the public company's capital structure and improve the efficiency of the corporate governance. 展开更多

Objective To evaluate the results of surgery on intercondylar of humerus. Methods Fifty-eight cases (26 males, 32 females), in an average age of 46. 6 (13 ~ 82 years), of intercondylar fracture of the humerus operated from September 1988 to September 1998 were followed up 29 months (8 ~ 63 months). According to the AO/MSIF classification 8, 7 and 5 cases were divided into type B1, B2 and B3 respectively while other 13, 10 and 15 patients into C1, C2 and C3 respectively. All the cases were evaluated by modified Jupiter assessment. Results Twenty-eight patients gained excellent results, while the good, fair and poor outcomes were found in twenty-two, three and five cases respectively. Conclusion Surgical treatment from posterior trans-olecranon approach with combination of internal fortion and bone graft, follwed by early active motion and adhesion relief procedure for elbow if necessary, was advocated in intercondylar fracture of humerus. 展开更多

This paper will analyze the history and evolvements of capital system in order to grasp the tendency of capital system reform. Managers should give more attention to the establishing of reform institution and the supervising of company capital system' s operation in the process of reform. Managers should also attach great importance to the third party and creditors when they value the interests of shareholders. It is imperfect to only emphasis or value the interests of the shareholders or the third party and creditors. In addition, creditor' s self-protection of civil action should obtain much more approaches in the process of reform. 展开更多
