Objective Use the automatic microbiological analysis system which for the streptococci (ATB rapid 32 Strep) to identify streptococci, and compare the examination speed and accuracy with the internationally recognized bacterium identification golden method API 20 Strep (streptococci identification biochemistry system) to enable the clinical microorganism room use ATB rapid 32 Strep identification system correctly, and provide the etiology basis to clinical promptly.Methods Isolate the bacterium from patient blood, cerebrospinal fluid, pig heart, pork and so on, then separate the streptococci in form to the blood plate, lay them in carbon dioxide incubator, after 35 ℃ 24 hours. Use ATB rapid 32 Strep,API 20 Strep and the traditional manual method to identify 18 strains of bacterias and carry on the medicine sensitive experiment.Results ATB rapid 32 Strep identified 16 strains as streptococcus suis II, 2 strains as streptococcus bovis II; API 20 Strep identified 17 strains as streptococcus suis II, 1 strain can not be identified; the tradition manually method identified all of the 18 strains as streptococcus group D . These 18 strains all sensitive to the Chloramphenicol , clindamycin, erythromycin, levofloxacin, penicillin, quinupristin/dalfopristin, cefotaxime, vancomycin and sulfafurazole , and resistant to the tetracyclin.Conclusion ATB rapid 32 Strep can identify the streptococcus suis in 4 hours , and the coincidence rate with API 20 Strep is 94.4%.So ATB rapid 32 Strep is one kind of system which could identify bacterium simply,quickly,accurately,and provide infectious disease etiology information for clinical immediately, satisfy the requirement of clinician and the microorganism examines.

The dynamica changes of the activity of serum tumor necrosis factor(TNF)was determined in 24 patients with severe burns,and the changes of cardiac and hepatic enzymes,plasma lactate and glucose,serum protein,WBC count etc were determined as well.It was found that TNF was produced in large amounts to damage and degenerate the vascular endothe-lium.Consequently intravascular emboli were more liable to occur to result in tissue hypoxia.TNF could also induce the release of polymorphonuclear neutrophils(PMNs)from the bone marrow.PMNs by chemotacsis accumulated in the inflammatory tissues to produce large amounts of toxic products,which could damage the cells and tissues directly to result in multiple organ failure.Furthermore,TNF,through the mediation of pyrogen and cachectin,could induce febrile reaction,exhaustion of glycogen reserve,and increment of muscular protein catabolism.Eventually the energy consumption of the host would be incresed and his defensive function weakened.

Objective:To explore the application of standardized treatment process for early enteral nutrition combined with gastric retention after operation in patients with esophageal cancer.Methods:Using convenience sampling, 84 patients with gastric retention complicated by early enteral nutrition support after esophagectomy in Department of Thoracic Surgery, Third People′s Hospital of Dalian from July 2015 to June 2020 were selected as the subjects. They were divided into control group and experimental group according to admission time with 42 cases in each group. The control group received routine nursing, while the experimental group received early enteral nutrition and gastric retention standardized treatment process nursing. The differences between the two groups in nutritional status and immune indexes before and 7 days after operation, the standard feeding rate within 7 days after operation, incidence of postoperative complications and enteral nutrition-related complications, length of hospitalization time and hospitalization expenses were compared.Results:In the control group, 2 cases were lost to follow-up. There was no statistically significant difference in preoperative nutritional status and immune indexes between the two groups ( P<0.05); 7 days after operation, the body mass index, serum total protein, prealbumin, nitrogen balance, IgM, CD3, CD4, and CD4/CD8 of the experimental group were all higher than those of the control group, and the differences between the two groups were statistically significant ( t values were 2.228-5.332, P<0.05 or 0.01).The standard feeding rate within 7 days was (68.93±8.12)% in the experimental group and (51.19±6.96)% in the control group, respectively, and the difference between the two groups was statistically significant ( t value was -4.38, P<0.01). The incidence of postoperative nausea and vomiting, Ⅱ B healing, anastomotic fistula and aspiration was 2.38% (1/42), 2.38% (1/42) and 0 (0/42), 2.38% (1/42) in the experimental group and 15.00%(6/40), 7.50% (3/40) and 5.00% (2/40) and 10.00% (4/40) in the control group, respectively, and the differences were statistically significant ( χ2 values were 5.99 - 9.88, P< 0.05 or 0.01). The length of hospitalization time in the experimental group was (10.18±1.69) d, and the hospitalization cost was (53 268.46 ±3 651.56) yuan, both lower than (13.66 ± 2.18) d and (64 972.39 ± 4 029.81) yuan in the control group, and the difference was statistically significant ( t values were 2.14, 2.89, P< 0.05). Conclusions:The standardized treatment process of enteral nutrition combined with gastric retention can improve the feeding rate, nutritional index and immune index within 7 days after operation, reduce postoperative complications and incidence of enteral nutrition related complications, reduce the hospitalization time and reduce hospitalization expenses.
