In this paper,we summarized nursing care of 9 patients with cytokine release syndrome after receiving the chimeric antigen receptor T cells immunotherapy.Key points of nursing care were as follows:comfortable and effective antipyresis,preventive rehydration,multiple methods of blood oxygen saturation improvement,iatrogenic pressure ulcer prevention,frequent vital signs monitor,close observation of level of cytokine and inflammatory factors,timely and accurate medication,formulating personalized nursing plan according to patients' condition,close collaboration between doctors and nurses.At last,8 patients recovered and were discharged,and 1 case died due to multiple organ dysfunction syndrome.

The cause of dilated cardiomyopthy (DCM) has not been elucidated yet .The poor prognosis and lack of specific and effective treatment became a serious health problem .Therefore to establish animal models of DCM to study the pathogenesis and treatment is necessary and urgent .At present the molding method of DCM mainly includes drug induction, immunological induction and molecular biology , etc.This article reviews the mature and commonly used establishing methods and mechanism of DCM models .

OBJECTIVETo study the effects of Dipsacus total saponins on the ability of learning and memory and its mechanism of action.

METHODSForty rats were randomly divided into blank control group, model group, Dipsacus group and positive control group (n = 10), general situation of rats were observed, the ability of learning and memory of rats was tested by Square water maze, the activities of acetylcholinesterase (AChE)and choline acetyltransferase (ChAT) of hippocampus in rats were measured using double antibody sandwich method.

RESULTSDuring the period of treatment, general situation had no obvious change in model group, but general situation and the ability of activity were gradually improved in Dipsacus group and positive control group. Compared with blank control group, the swimming time was obviously prolonged and the number of mistakes was obviously increased at different time, the activity of AChE was significantly enhanced and the activity of ChAT was significantly decreased in model group. Compared with model group, the swimming time was obviously shortened and the number of mistakes was obviously reduced at different time, the activities of AChE were significantly decreased and the activities of ChAT were significantly enhanced in Dipsacus group and positive control group; Compared with positive control group, the swimming time and the number of mistakes at different time and the activities of AChE and ChAT had no significant difference in Dipsacus group.

CONCLUSIONDipsacus total saponins can improve the ability of learning and memory in Alzheimer' s disease(AD) rats, its mechanism of 'action may be related to regulating ACh metabolism of hippocampus.

Based on the research goal of "traditional Chinese medicine standards lead in the international standard-setting", scientific strategies for the elaboration of traditional Chinese medicine (TCM) comprehensive quality standard system were introduced. TCM is a complex multi-component system which was used under the guidance of traditional Chinese medical theory. The present paper has put forward the basic principle of " deep research and simplified standard" to construct the quality standards of TCM. " Deep research" refers to systematic, thorough investigations on active constituents and biological mechanisms. On the basis of deep research, "simplified standard" means to establish a scientific and feasible standard, which should be practical and less complicated, to control the quality of Chinese herbs. Three key issues related to the elaboration of the quality standards are suggested. For reference substances, we propose the research methodology using reference extract to develop the qualitative and quantitative determination methods. Compared with that of using reference compounds, the preparation of reference extract is more accessible, economical and practical. Moreover, compared with reference crude drugs, the reference extract showed better batch-to-batch consistency. For identification, in addition to conventional methods, high performance liquid chromatography (HPLC), chemical fingerprints and characteristic chromatogram are proposed, in which more major marker compounds are monitored. And then LC-MS technique is employed to comprehensively analyze and characterize the peaks in the fingerprint. For multi-component quantification, the method of single standard to determine multi-components (SSDMC) is suggested, providing solutions for the lack of reference standards in quality evaluation. The SSDMC method uses a single reference standard to simultaneously determine the content of multiple compounds. In general, the integrate quality control standard of TCM is established based on combining innovative technology with practical applications.

Keratoconus is a progressive, non - inflammatory corneal thinning disorder that produces a unique spectrum of change in the surface curvature of the cornea. The suspected factors associated with the cause of keratoconus include genetic mechanisms, familial associations, allergy, atopy and so on, but environmental factors, such as abnormal rubbing, contact lens wearing and ultraviolet radiation may be easily ignored. Although it is commonly thought that keratoconus is a result of various pathological progress mediated by multiple factors, those chronic trauma could play important roles in the pathological progress. The classic definition of keratoconus is still referred as a non - inflammation disorder with malnutrition of keratectasia, more and more clinical evidences and experimental results that may refute this concept. It may be due to the long-term persistent chronic trauma resulted from eye rubbing, contact lens or ultraviolet radiation. Under this conditions, the increased release of inflammatory mediators and matrix metalloproteinases may accelerate keratocyte apoposis and enzyme metabolism disorders, with the result of matrix cell lost, tensile strength decreased and keratectasia. Here, for some papers known about the relationship between chronic cornea trauma and keratoconus were reviewed and discussed its possible causal relationship.

Objective To approach therapy of acute lymphoblastic leukemia(ALL) complicating acute respiratory distress syndrome (ARDS) in children.Methods The therapy of seven children diagnosed as ALL complicating ARDS was analyzed, who were treated by anti-infection, methyllprednisolone, ambroxol and constant positive airway pressure (CPAP) assisted ventilation.Results Six cases were recovery and one was death. The cure rate was 85.7%. Conclusion The cure rate is high, when employing combined therapy to treat ALL complicating ARDS.

Objectives:To observe the role of nutritional support in patients after liver transplantation. Methods:Nutritional support was used in three patients after orthotopic liver transplantation(OLT).Total parenteral nutrition(TPN) was administered since the second day after the operation,the combination of enteral nutrition(EN) and parenteral nutrition(PN) was followed and then total enteral nutrition(TEN) was adopted.After that,oral intake of food was restored. Results:Postoperative patients were restored well. Conclusions:The supply of nutrition for patients after liver transplantation should be TPN→PN+EN→TEN,and then gradually increased.Once the gastroenteric functions of patients recover it is advisable to start EN as soon as possible.

Objective To predict the B cell epitopes for S protein of severe acute respiratory syndrome (SARS) coronavirus. Methods Based on SARS coronavirus genome sequence and the analysis of the flexible regions of secondary structure for S protein, the B cell epitopes for S protein were predicted by methods of Kyte Doolittle hydrophilicity plot, Emini, and Jameson Wolf. Results The computer predicted most possible epitopes for S protein were located within or nearby its N terminal No. 91-98, 1121-1153 and 185-193. The N terminal No. 1050-1059, 752-765, 41-50, 666-674, 264-287, 340-348, 408-416, and 424-439 may be the possible B cell epitopes. Conclusion Prediction of the B cell epitopes for the S protein based on multiple parameters is helpful for the identification of B cell epitopes using experimental methods.
