Deubiquitylases remove ubiquitin moieties from different substrates to regulate protein activity and cell homeostasis .Since this posttranslational modification plays a role in several different cellular functions ,its deregulation has been associated with different pathologies .Aberrant expression of Ubiquitin -Specific Peptidase 22(USP22)has been associated with poor cancer prognosis .This article reviews the research status of USP 22.

Objective:To explore the influence of continuous quality improvement of nursing care on the compliance of senile patient with gastroscopy.Methods: 100 senile patients with gastroscopy were selected, and they were divided into control and improvement groups ( each group included 50 cases ) depended on the different time of hospitalization. The control group was treated with routine nursing quality method, while the improvement group was treated with continuous quality improvement method. A series of indicators in the endoscopic examination, such as the success rate of one time intubation, the used time, yes or no cough and other adverse reactions and the patient's satisfaction for nursing services were compared between the two groups.Results:After 5 months of continuous quality improvement nursing, the success rate of one time intubation in the improvement group was significantly higher than that in the control group, and the checking time of improvement group was significantly less than that of control group, the differences were statistically significant(t=7.162,t=6.61; P<0.01). Besides, on check process, the incidence of adverse reactions in the improvement group was significantly lower than that in the control group and the satisfaction of nursing service was significantly higher than that of the control group, the differences were statistically significant(x2=23.077,x2=10.699,P<0.01).Conclusion:The application of continuous quality improvement nursing for senile patients during gastroscopy can improve the success rate of one time intubation, shorten the gastroscopy time, reduce the incidence of adverse reactions, enhance compliance of gastroscopy and satisfaction for nursing service, and its clinical effect is obvious.

This report presents 3 cases of Castleman's disease in the head and neck.The clinical symptom,pathlogical and imaging features of the Castleman's disease are introduced.

OBJECTIVE:To investigate the characteristics of adverse drug reactions(ADR)of the hospitals(Level 2 and above) of Wuxi in order to promote rational use of drugs in the clinic.METHODS:2 473 cases of ADR collected from Jan.2005 to Dec.2006 in 11 hospitals(Level 2 and above)of Wuxi were retrospectively studied.RESULTS:Most patients who had ADR were old patients over 60 years and teenagers(≤10years).Most ADR were caused by anti-infection drugs(60.9%),followed by the preparations of Chinese materia medica(13.7%).The intravenous medication was the main route of medication resulting in serious adverse reactions;Most of the ADR cases were known and mild, 74 cases were severe and scarce(3.0%).CONCLU-SION:More attention should be paid to monitoring clinical ADR and the quality of ADR reports needs to be improved.

Objective To study the TCM syndromes and diagnosis of patients after percutaneous coronary intervention(PCI).Methods The clinical epidemiological method was adopted in the study and the symptoms and signs including the manifestations of tongue and pulse of 143 patients after PCI were recorded for the variable cluster analysis.Results The most of frequently appeared symptoms and signs of patients after PCI were chest pain,chest distress,lassitude,irritability,frequent micturition at night,obesity,dark lips and ecchymosis on the tongue.The 6 involved syndromes of the patients were qi deficiency with phlegm retention,kidney deficiency with blood stasis,liver qi stagnation,qi deficiency of spleen,qi deficiency of heart,and deficiency of both qi and yin.The diagnostic points of each of them were set up.Conclusion Six syndrome type could be classified in patients after PCI,and analysis base on diagnostic information set up the diagnostic points.

Epithelial-mesenchymal transition is closely related with invasion and metastasis of malig-nant tumor and is focused on invasion and metastasis in malignant tumor in recent years .Many researches dermon-strate that epithelial-mesenchymal transition is involved in invasion and metastasis of several malignant tumors , such as breast cancer ,ovary cancer and non -small cell lung cancer .The relevant signal pathways and molecular proteins are also studied .Research progress of epithelial -mesenchymal transition in non -small cell lung cancer for invasion and metastasis is reviewed in this article .

Objective To design and implement the academic impact power information platform for the secondary disciplines of clinical medicine in order to keep abreast of their advantages and disadvantages. Methods An index system for the assessment of secondary disciplines of clinical medicine was constructed with the bibliometric methods according to the factual data. Results Its functions of query analysis, batch input, and editing of the index data of different disciplines were achieved in higher education institutions using the ASP. NET technology based on the data processing, indexing and statistical analysis. Conclusion The platform can provide the data support for the develop-ment and scientific research management of secondary disciplines, and thus playing an important role in promoting the innovative research and management of clinical medicine.

Objective:To investigate the effects of PHT on the differentiation of rat bone marrow mesenchymal stem cells(BMSCs) into vascular endothelial cells(VECs).Methods:rBMSCs were cultured in indirect coculture system with VECs and independent culture system in the presence of phenytoin at 0,20 and 40 μg/ml respectively.After 1 4 d culture the mRNA expression levels of the intercellular adhesion molecule-1 (ICAM-1 ),vascular cell adhesion molecules-1 (VCAM-1 ),vascular endothelial growth factor re-ceptor -2(KDR)and Runt-related transcription factor 2 (RUNX2)were detected by real-time PCR.Results:The expression levels of ICAM-1 ,KDR and RUNX2 were upregulated in rBMSCs by PHT treatment.The expression levels of ICAM-1 ,KDR and RUNX2 in the co-culture groups were higher than those in the independent culture groups of rBMSCs treated by PHT at the same concentra-tion.The expression level of VCAM-1 in co-culture groups was lower than that in the independent culture groups.Conclusion:PHT may promote rBMSCs differentiation into rVECs in the co-culture system.

OBJECTIVE:To study the mechanisms of GJKL(Gujikang liniment) in treatment of soft tissue injury METHO_DS:The effects of intraperitoneal injection of acetic acid solution on capillary permeability were observed;An animal model of soft tissue injury was established by striking The effects of GJKL on hemorheological parameters were observed RESULTS:GJKL markedly inhibited capillary permeability and decreased hemorheological parameters CONCLUSION:GJKL takes therapeutic effects on soft tissue injury through inhibiting the increased capillary permeability and reducing the hemorheological parameters

Mast cells (MCs) play a key role in the pat hogenesis of allergic diseases. Tissue MCs are originated from hematopoietic ste m cells in bone marrow. In recent years, it was reported that human mast cells c ould be differentiated from stem cells of umbilical cord blood. In this review, we summarize the development in this novel area.
