Patients with SAP have a hypermetabolic and hypercatabolic state.Nutritional support for patients with SAP is needed.EN by the jejunal route does not stimulate pancreatic secretions and is safe.At present,the beneficeal effects of EN towards improving the nutritional condition,protecting gut barrier function,reducing translocation of bacteria and endotoxins,modulating the inflammatory response,and decreasing the cost have been observed.Therefore,the EN rather than PN should be used by the jejunal route to provide nutritional support for patients with SAP.

Acute kidney injury(AKI) is a common clinical severe emergency in children,with high morbidity,mortality and poor prognosis.The traditional indicators such as serum creatinine and urine can't diagnose early.Recently,with the deepening research of AKI,many higher specific and sensitive biomarkers have been found.But the study of biomarkers in children is behind the adult,and the etiology,pathophysiology of AKI in children have great difference from adult.So this paper will show the advances of biomarkers in children of AKI.

Objective To discuss the therapeutic effect of recombinant human CTLA-4Ig fusion protein (rhCTLA-4Ig) on rheumatoid arthritis (RA) patients and the change of T helper cells 17 (Th1 7 ) and regulatory T (Treg) cells.Methods Forty-eight active RA patients were randomly divided into the treatment group and the control group.Treatment group received 12 weeks of infusions of rhCTLA-4Ig ( 10 mg/kg),while the control group received 12 weeks of infusions of placebo.The changes of expression levels of Th17cell were detected by flow cytometry.The changes of expression level of FoxP3 in monocytes of the peripheral blood were examined by RT-PCR.T test and x2 test were used for statistical analysis.Results ① Eighteen of 24 cases in treatment group showed good ACR20 changes after 12 weeks,the effective rate (75％) was significantly higher than that of the control group ( 1/24,4％ ).After treatment,DAS28 score of the treatment group (3.0±0.7) was significantly lower than that of the control group(6.9±0.7) (t=-12.39,P＜0.01 ).② Compared with the Th17 monocytes of the peripheral blood from active RA patients of treatment group after therapy (0.22±0.20)％,the Th17 monocytes of peripheral blood from active RA patients of the control group (1.63±0.47)％ were higher (t=5.61,P＜0.05 ).③ Compared with the FoxP3 mRNA of the control group (0.24±0.05),that of the treatment group (0.88±0.18) was significantly higher after therapy (t=7.56,P＜0.01 ).Conclusion The clinical parameters of RA patients have improved significantly after the treatment,and the Th17 and Treg cells balance is also restored after rhCTLA-4Ig therapy.

Objective To observe clinical effect of treating glaucoma with compound trabeeuleetomy combined with activating blood circulation and promoting diuresis Chinese medicine. Methods 42 cases with glaucoma were randomly divided into two groups by means of random number table. The control group was treated with compound trabeculeetomy, and the treatment group was treated with Chinese medicine after compound trabeeuleetomy. The regular reexamination was performed, and follow-up visit was executed for an average of 12 months. Results Compared with the control group, the postoperative vision in the treatment group increased significantly (λ2=4.511, P<0.05) , and intraocular pressure decreased significantly (λ2=3.638,P< 0.05); The rate of anterior chamber in the treatment group was lower than that of the control group(λ2=4.256 P< 0.05) . Both groups had filtering bleb, and the rate of non-functional filter blebs in the treatment group was lower than that of the control group (λ2=3.054, P< 0.05 ) . Conclusion The therapy of compound trabeculectomy combined with Chinese medicine on glaucoma was better than compound trabeculeetomy only.

Toxic epidermal necrolysis (TEN) is an acute skin inflammation,which belongs to heavy drug eruption.With the extensive and widespread use of antibiotics,nonsteroidal antipyretic analgesics and other pharmacotherapies in the treatment of critically ill patients,the trend of morbidity of TEN is gradually increased,especially in intensive care unit.In consideration of the high mortality rate of TEN and its great influence on the overall prognosis of patients with critical illness,we summarized the diagnosis and treatment experiences in the management of TEN based on retrospective analysis of one patient with severe acute pancreatitis and TEN.

Objective To elucidate the clinical features, diagnosis and treatment of Aspergillus necrotizing bronchitis. Methods Medical records and investigation data from 5 eases of Aspergillus necrotizing bronchitis were retrospectively analyzed, and related literatures were reviewed. Results Five patients (3 males and 2 females) with mean age of 63.6 y were enrolled in this study. All patients had histopathologically proved necrotizing aspergillosis of the large airways. Common presentations included cough, short of breath, sputum production, fever and haemoptysis. Tracheoscopy presentations included necrosis, mucous hyperemia, focal airway constriction and neoplasm. The CT findings included bronchial wall thickening, narrowing of the bronchial lumen, which was often associated with distal obstructive pneumonia. Conclusions The clinical manifestations of Aspergillus necrotizing bronchitis are nonspecific, and histopatholagical diagnosis is essential for a definite diagnosis and can be supported by tracheoscope or imaging techniques.

Objective To explore the factors influencing the intra-laboratory turnaround time ( ILTAT) and establish a COX regression model.Methods Data of 5 weeks with a total of 904 cases from the samples of blood routine examinations from January 2014 to June 2014 in The Third Hospital of Xingtai were randomly collected.The records of the samples included test dates , times of arrival , times of test , sample statuses, time consumption, time duration, operators, project portfolios, delay, PLT counts, results of 30-minute treatment and test weeks.Based on SPSS 17.0, the above indicators were analyzed by COX single factor analysis and then COX mutiple-factor regression analysis.Results Within the prescribed time , 421 cases were sent taking up 46.6%of the total samples.The ratios of sent cases in 10, 20, 30, 40 and 50 minutes are 10.4%, 24.7%, 46.6%, 58.7% and 82.1% respectively.The results of COX single factor analysis showed that times of arrival , sample statuses, times of examination, operators, project portfolios and delay had statistical significance for ILTAT ( P<0.05 ).The results of COX multiple-factor analysis indicated that right times of arrival had a positive impact in reducing the turnaround time of samples (Wald=40.446,P=0.000);non-office hours, project portfolios, physical check samples, and handovers were unfavorable factors to shorten ILTAT ( Wald =7.904,38.029,42.874,18.617, P =0.005,0.000, 0.000,0.000);Operator 5 was a favorable factor(Wald=11.039, P=0.001) and Operator 3 and Operator 10 were unfavorable factors ( Wald =6.432, 24.242, P =0.011, 0.000 ); no obvious discrepancy was observed for other operators (P>0.05).Conclusions Times of arrival, times of test, operators, project portfolios and delay were the independent risk factors leading to the delay in ILTAT.Other laboratories could determine the variable number of proportional hazards models based on their sample transport , test procedures and principal influence factors , and carry out quantitative evaluation on the factors in sample processing for improvement.Thus, significant decrease on ILTAT would be achieved.

Objective To observe the relationship between pregnancy-associated plasma protein-A (PAPP-A), C-reactive protein (CRP) and acute coronary syndrome (ACS). Methods Sixty-eight patients with coronary artery disease, who were confirmed by angiography, were enrolled in this study. Among them, there were 43 cases with ACS and 25 cases with stable angina. At the same time, randomly selective 20 healthy subjects served as control group. Plasma PAPP-A and CRP levels were measured by using untrasensitive immunosorbent assay (ELISA). Results The plasma levels of PAPP-A and CRP were significantly higher in ACS patients than those in control group (PAPP-A: 17.9?8.7mIu/L VS 7.1?4.2mIu/L, P1, which indicated both were the risk factors of ACS. Conclusion The plasma levels of PAPP-A and CRP increased in ACS patients, and both PAPP-A and CRP were independent risk factors of ACS.
