The traditional management of severe intraabdominal infection include source control and antibiotics application.Fluid resuscitation and open abdomen management are recent development in the treatment of severe intraabdominal infection.The overall morbidity of severe intraabdominal infection was decreased under 20％ by these comprehensive treatment.Because of edema,inflammation and gastrointestinal dysfunction,the intraabdominal pressure was increased,the peritoneal infusion pressure was decreased and the perfusion was insufficient,and leaving abdomen open can reverse these condition,and is helpful for debridement and drainage of the source of infection,as well as management of bleeding and intestinal fistula.Entero-atmospheric fistula is the main severe complication after open abdomen,and it should be prevented by temporary abdominal closure and early closure of the wound.

Impaired recognition of foreign nucleic acid initiates abnormal mucosal immune responses in intestine.Very little is known on how microbial DNA activates intracellular DNA sensors and controls the function of antigen-presenting cells to shape mucosal immune responses in inflammatory bowel disease (IBD).In current review,we will introduce mucosal dendritic cell population,describe newly identified cGAS-cGAMP-STING complex,and identify certain IBD susceptibility genes that associate with impaired microbial DNA recognition in human.

With the rise of the incidence of Crohn's disease,clinicians began to recognize and pay attention to this disease.There is no effective method to cure the Crohn's disease currently,and the complications of the Crohn's disease are numerous and complex.Therefore,early diagnosis and treatment are very important.Due to many factors,the problen of diagnostic delay is widespread.Female patients diagnosed younger than 40 years old,the presence of ileal disease,use of non-steroidal anti-inflammatory agents,smoking history,parental symptoms are risk factors of diagnostic delay of Crohn's disease.Delayed diagnosis might increase the risk of complications,especially intestinal stenosis and operation-related complications.Crohn's disease needs to be early diagnosed and treated to improve the prognosis of patients.

Objective To determine the effectiveness and medical cost-effectiveness of clinical rehabilitation for promoting the functional recovery of sub-acute cerebral infarction patients.Methods Totally 247 sub-acute patients with cerebral infarction were randomly divided into a clinical rehabilitation group of 129 and a routine rehabilitation group of 118.The clinical group received a standardized rehabilitation intervention and drug treatment,while the routine rehabilitation group received routine rehabilitation therapy and drug treatment.The Fugl-Meyer assessment (FMA) and the modified Barthel index (MBI) were used to compare the two groups after the treatment and 3 and 6 weeks later.The hospital cost for six weeks was also compared between the 2 groups.Results At 3 and 6 weeks,improvement in the average FMA and MBI scores was observed in both groups but the inter-group differences were not significant.The total hospital cost of the clinical group was,however,significantly less than that of the others.Conclusion Clinical rehabilitation can improve the motor function and ability in the activities of daily living of stroke patients.It also has economic benefits.

Crohn disease (CD) is a chronic inflammatory disease which progressively affects the digestive tract with unknown etiology. During the disease course, intestinal fibrosis will gradually develop in many CD patients and results in irreversible fibrosis stricture, causing refractory abdominal pain and even intestinal obstruction, and necessitating one or more surgical interventions. Thus far the exact etiology of CD remains unknown. It is believed that genetic, environmental and immunologic factors are involved, which may also predict the development of intestinal fibrosis. Recent studies have found the association of mutations in genes, such as NOD2, ATG16L1, CX3CR1, IL-23R and MMP3 with the fibrogenic phenotype of CD. In addition, serum extracellular matrix molecules, growth factors, miRNAs and microbial antibodies have also been linked to the fibrogenesis in CD patients, however the results of researches were divergent. Therefore it is of significance to explore noninvasive markers of intestinal fibrosis with high sensitivity and specificity, and the high-throughput proteomic technique may be an approach that deserves further investigation. Screening the high-risk patients for the fibrostenotic phenotype of CD by susceptibility genes, and early detection of intestinal fibrosis using noninvasive serum markers, will help improve the treatment outcomes and reduce the surgical rates. The article aims at summarizing the current susceptibility genes and serum markers of intestinal fibrosis in CD.

Crohn's disease (CD) is a chronic inflammatory disorder affecting any part of the digestive tract which relapses and remits throughout the disease course. It occurs in individuals with genetic susceptibility and involves an abnormal response of the immune system to the external environment. Besides, improved hygiene, abuse of antibiotics, westernization of diet with high sugar and fat are thought to be associated with rapidly increasing incidence of CD. Certain components of foods may influence gut inflammation through antigen presentation and alteration of the microflora. This article aims mainly to review diet-related clinical studies to outline its roles in the pathogenesis and progress of disease, and then give some evidence-based suggestions.

In order to learn the enzymatic hydrolysis characteristics of steam-explosion pretreated corn straw by cellulase, the effects of substrate concentration, cellulase concentration and temperature were determined. The kinetics of the hydrolysis reaction could be described with the Michealis-Menten equation, and the hydrolysis reaction obeyed the classical first-order reaction rate in the first three hours. In the condition of 45 degrees C and pH 5.0 and the stirring rate 120 r/min, the Michealis constant (Km) and maximum rate (Vm) for 1.2 FPU/mL of cellulase were 11.71 g/L and 1.5 g/(L x h). The kinetic model, including the parameters such as substrate concentration, enzymatic concentration and temperature, was suit for the hydrolysis reaction under the temperature range from 30 degrees C-50 degrees C.

Multiple factors can lead to treatment failure and death in the patients with intra-abdominal infection.These factors include advanced age,malignancy,significant cardiovascular compromise,significant liver and renal diseases,hypoalbuminemia,diffuse peritonitis,delayed initial source control,delayed and unexpected initial source control,and suspected infection with resistant pathogens.Scoring system such as Mannheim Peritonitis Index (MPI) and complicated intra-abdominal score can also help to evaluate the risk of intra-abdominal infection patients.Sepsis and septic shock are important risk factors.Treatment strategies include prompt resuscitation and organ function support,early appropriate source control measures,effective antibiotics coverage of pathogens,prevention and treatment of resistant bacterial.

OBJECTIVETo investigate the effect of rehabilitation therapy for short bowel syndrome on patient nutritional status and intestinal adaptation.

METHODSThe rehabilitation therapy included enteral or parenteral nutrition, glutamine, recombinant human growth hormone and rehabilitative diet. From January 1997 to July 2000, twenty - seven patients with short bowel syndrome received the treatment. The average age of the patients was 38.5 +/- 19.3 years, and the length of residual small intestine ranged from 15 to 80 cm, with an average of 46.8 +/- 23.4 cm. The ileocecal valve was preserved in 14 cases, and the average time between the onset of short bowel syndrome and the rehabilitation therapy was 86 +/- 105 days.

RESULTSAfter the treatment, nutritional status of the patients improved markedly, and intestinal absorptive capacity improved. Eight patients were followed up for more than 2 years, among whom 4 (50%) were weaned from total parenteral nutrition. Thirteen patients were followed up for more than 1 year, and 10 patients (76.9%) were weaned from total parenteral nutrition.

CONCLUSIONSRehabilitation therapy for short bowel syndrome can improve patient nutritional status effectively and promote intestinal adaptation, providing a new hope for these patients. The therapeutic effects are related to the length of the residual small intestine, patients age and duration between massive intestinal resection and start of the treatment. Early initiation of rehabilitation therapy promotes intestinal adaptation and increases patients ability to wean from total parenteral nutrition.

OBJECTIVETo observe the therapeutic effects of S-Adenosyl-L-methionine(SAMe) in the treatment of cholestasis after total parenteral nutrition (TPN).

METHODSThirty SD rats were randomly divided into control group, hypercalorie group, hypercalorie adds SAMe group; sepsis group and sepsis adds SAMe group; their stages of cholestasis were compared. Sixteen patients received SAMe because of cholestasis after prolonged TPN.

RESULTSBile flow, serum levels of total bile acid and gamma-glutamyl transpeptidase were elevated markedly in hypercalorie and sepsis groups. Hepatocellular fatty degeneration, dilatation of cholangiole, and bile sludge could be seen microscopically, while SAMe administration in hypercalorie adds SAMe and sepsis adds SAMe groups could increase bile flow, decrease serum total bile acid and gamma-glutamyl transpeptidase levels. Microscopic findings were normal, no dilated cholangiole or bile sludge could be found. Cholestasis and abnormal results of liver function test were the main clinical manifestations of 16 patients before SAMe administration. Three weeks after SAMe administration, their serum levels of total bilirubin, alkaline phosphotase, gamma-glutamyl transpeptidase, alanine aminotransferase(ALT), and aspartate aminotransferase(AST) were decreased markedly; they became normal in the 4 th week.

CONCLUSIONSAMe could prevent and treat cholestasis without discontinuation of TPN.
