The modest pressure promotes the graduate to keep continuous energy and focus on scientific research,but too much pressure will lead to mental problem and serious moral shortcoming.Reformation of scientific evaluating and promoting system,enhancement of scientific interest and reconstruction of mental training system should be the important ways to release the pressure of scientific research of the graduate.

In addition to the operation technique and procedure selection, the dysfunction of important organs such as heart, lung, kidney and liver plays an important role in restricting the recovery of patients and the prognosis of gastrointestinal surgery. For patients complicated by one or more organs dysfunction after operation, who have no response to conventional therapies, extracorporeal life support/replacement should be used as early as possible. The extracorporeal organ support provides more time for rescue, and relieves injured organs to "rest" and accelerates recovery, which improves the survival of critically ill patients who suffered after gastrointestinal surgery. Nowadays, the safety and efficiency of the extracorporeal life support/replacement, including heart, lung, kidney, liver and intestine, are developing quickly, and easy to achieve, however, limitations still exist. With the development of nanotechnology and bioartificial membranes, an open and total extracorporeal life support system, which can simultaneously supports heart, lung, kidney, liver, intestine and brain, will be produced in the future, further improving the survival of critically ill patients.

Refractory constipations are mostly mixed constipations. Surgery is only reserved as the last option when conservative treatments have failed. Colectomy or stapbed transanal rectal resection (STARR) represents the procedure of choice in patients with pure slow transmit constipation (STC) or obstructive defecation syndrome (ODS). However, its clinical outcome is unsatisfactory. Jinling procedure, a new surgical innovation for mixed constipation, aims to correct the coexistence of STC and ODS in severe refractory constipation. It combines subtotal colectomy and side to side cecorectal anastomosis, which shows a promising clinical outcome in over 500 refractory constipation patients. In our department, there is no significant difference in operation time, mortality and complications between the laparoscopic assisted and open Jinling procedures. Jinling procedure is also appropriate for secondary Hirschsprung's disease. Stoma is described in the treatment of some adult constipation patients, which has not been supported by the evidence-based medicine at present. Anastomosis leakage is a severe complication after constipation surgery. Fecal diversion is indicated once it happened. Colon irrigation may be used in patients who failed after surgery or children who refused definitive operation. It has showed a good short-term functional recovery but becomes invalid after a long-term follow-up.

In recent years, damage control is well established as a potentially life-saving procedure in a few selected critically injured patients. The "damage control" concept also has been shown to increase overall survival and is likely to modify the management of critically ill patients suffering from gastrointestinal disease. In these patients the "lethal triad" of hypothermia, acidosis, and coagulopathy acts as a vicious cycle that often can not be interrupted and marks the limit of the patient's ability to cope with the physiological consequences of traditional and extensive surgical procedures. The principles of damage control are to control bleeding, obstruction, and/or infection until the physiologic derangement has been restored and the patient could undergo a prolonged operation for definitive repair. This approach is unfolded in three phases. During the initial operation, the surgeon carries out only the absolute minimum necessary to improve patient's condition and to control bleeding, obstruction, and/or infection. The second phase consists of secondary resuscitation in the intensive care unit, characterized by maximization of hemodynamics, correction of coagulopathy, rewarming, and complete ventilatory support. During the third phase, definitive operation is performed.

ObjectiveTo evaluate the efficacy and safety of ibutilide for conversion of paroxysmal and persistent atrial fibrillation.Methods31 patients with atrial fibrillation duration less than 90 days were included into amiodrone or ibutilide group.16 patients were intravenously administer with amiodrone and 15 patients with ibutilide separately.Conversion rate,time needed to converse and adverse effects were compared between two groups.ResultsThe total conversion rate of ibutilide group was significantly higher than that of amiodrone group (66.7％ vs 37.5％,x2 =1.98,P ＜ 0.05 ).Time needed to converse was significantly shortened in ibutilide group compared with amiodrone group [ ( 31.75 ± 7.39 ) min vs ( 51.87 ± 9.26 ) min,t =3.67,P ＜ 0.05 ].No clinical significant adverse effects were observed in ibutilide group.ConclusionIntravenous administration of ibutilide in cardioversion of paroxysmal and persistent atrial fibrillation was more safe and effective than amiodrone.
