Objective:To explore grouping methods of subdividing adjacent diagnosis related groups(DRGs) by introducing patient clinical complexity level(PCCL) principle and provide references for exploring DRG grouping method in line with context in China.Methods:Clinical complexity level of each complication was assigned by clinicians.PCCL model was selected to calculate the scores of clinical complexity cases.Each adjacent DRG was subdivided into DRG groups by classification and regression trees(CART) model.The rank-sum test was applied to test the statistical significances of the grouping results.Results:9 surgical adjacent DRGs were subdivided into 18 DRG groups.There were statistical significances in the differences of hospitalization expenses and length of stay among different DRG groups in each adjacent group.Conclusion:PCCL model showed high performance in DRG subdivision.The unification of the quality of medical records and coding were the key factors to ensure the reasonable grouping results.

Objective To compare clinical effect of MTA and Vitapex for young permanent teeth with periapical incomplete apical closuret . Method Teeth 90 were chosen from 80 patients at 7-25 years old young permanent teeth with periapical and randomly divided into MTA group and Vitapex group 45 in each group.Two groups were treated with MTA and Vitapex paste treatment respectively.6-month and 12-month after treatment followed up, observed clinical efficacy of two groups.Results The six-month recall, X-ray ( MTA group 93.33%, Vitapex group 88.89%) and clinical parameters (MTA group 95.56%, Vitapex group 86.67%) success rate of two group was no significant difference.When the 12-month followed up, X-ray examination of MTA group's success rate was 93.33%, significantly higher than 68.89%Vitapex group (P<0.05), clinical indicators of success rate of 95.56%MTA group,significantly higher than the 71.11%Vitapex group (P<0.05).Pain during root canal therapy (EIP) of the occurrence, MTA group than Vitapex group (P<0.05).Conclusion The effect of short-term treatment of MTA in treatment of young permanent teeth with periapical incomplete apical closure is definite,it is an ideal induce apical molding material.

ObjectiveThe pre-hospital data of 839 emergency patients who were admitted to Naxiang Emergency Center of Shanghai from Dec 11 2006 to Jun 11 2007 were analyzed.The first five causes of emergency call were trauma,diseases of newborns,neuron-system diseases.eardio-vascuIar diseases and digestive diseases.The epidemiological data including gender,age of patients,distance to emergency site,duration of ambulance dispatch,results of first aid.etc were also presented in the paper.These data would be helpful for improving pre-hospital medical care of emergency patients.

ObjectiveTo evaluate the parenteral nutrition formula's character of all-in-one-mixed preparation and pre-mixed preparation applied for hospitalized patients in China.MethodsWe collected parenteral nutrition (PN) prescriptions in hospitalized patients with various diseases at dispensing centers of 6 hospitals in different areas of China. Statistic analysis was made by nutrients application, total liquid, nonprotein calories, total nitrogen, ratio of non-protein calories and total nitrogen, and ratio of glucose and fat. A comparison was made between all-in-one-mixed and pre-mixed preparation as to all the indices.Results The nutrients supply in all-in-one-mixed PN preparation, as well as in the pre-mixed PN preparations of 3 different energy degrees can meet the basic nutrition requirements of most patients. The total nitrogen supply in all-in-one-mixed PN prescriptions meets nutrition requirements in most patients, but the ratio of non-protein calories and total nitrogen[( 180-250) : 1]and the ratio of glucose and fat (0. 56-1.26)were significantly different from what a doctor would recommend[( 100-150) : 1, 1.0]. While the ratios in the pre-mixed PN preparation on 3 different energy degrees are more consistent with recommeded values,which are at 167 and 0. 8 respectively.ConclusionsAll-in-one-mixed and pre-mixed PN preparation have their own individual advantages and limits, and both of them can meet the requirements of most hospitalized patients. More attention should be paid to the nutrients proportion when doctors prescribe all-in-one-mixed PN preparations.

Objective To investigate the effects of chitosan/pCDNA3.1 (+) CrmA on matrix metalloproteinase (MMP)-1 and tissue inhibitor of metalloproteinase (TIMP)-1 expression of chondrocytes induced by interleukin-1β (IL-1β) in mRNA and protein levels.Methods Rabbit chondrocytes were isolated and cultured.Chondrocytes were treated with PBS,10 μg/ml chitosan (CS) and chitosan/ pCDNA3.1 (+)CrmA respectively for 6 hours.Then 10 ng/ml IL-1β was added into the culture medium.After 48 hours,real time polymerase chain reaction (real time PCR) and Western blot assay were used to examine the changes of MMP1 and TIMP-1 in mRNA and protein levels.Results In CS/pCDNA3.1 (+)CrmA treated group (0.44±0.04),the messenger RNA expression of MMP-1 in chondrocytes was significantly suppressed compared with corresponding samples of PBS treated group (1.00±0.05) and CS treated group (0.76±0.07),There was significant difference between three groups (F=106.93,P＜0.01).The MMP-1 protein expression of chondrocytes in CS/pCDNA3.1 (+)CrmA treated group (0.28±0.03) was lower than that of PBS treated group (0.73±0.06) and CS treated group (0.46±0.05)(F=59.66,P＜0.01).No significant difference of TIMP-1 expression among the three groups was observed in mRNA and protein levels.Conclusion CS/pCDNA3.1(+) CrmA can significantly inhibit the mRNA and protein expressions of MMP-1 of chondrocytes induced by IL-1β,which leads to up-regulation the ratio of TIMPs to MMPs of IL-1β induced chondrocytes.It may be a part of the mechanisms of the therapeutic effects of CS/pCDNA3.1 (+)CrmA on osteoarthritis.

Objective:To explore the relationship of lymphocyte function-associated antigen 3 (LFA-3, CD58) expression in glioma with clinical features and its role in clinical prognosis. Methods:Clinical data and mRNA microarray data of 514 patients with glioma were obtained from The Cancer Genome Atlas and were used to study the expression of LFA-3 (CD58). Cox regression was used to analyze the relationship between CD58 expression and survival of patients with glioma. Multivariate analysis of variance was used to further analyze the relationship of CD58 with age, sex, and pathological grade of glioma. Results:The results of the stratified χ2 test of CD58 expression and tumor grading were shown, considering tumor type, gender and age of diagnosis (all P<0.05). CD58 expression was sig-nificantly correlated with overall survival (OS) and disease-free survival (DFS) of patients with glioma. Patients with high CD58 expres-sion presented short OS and DFS (P<0.0001). Conclusion:CD58 possibly promotes tumorigenesis in gliomas and thus can serve as a potential tumor diagnostic marker and individual therapeutic target.
