Objective To provide references for enriching and innovating patterns of TCM syndrome differentiation by exploring the relationship between pathological changes and TCM syndrome differentiation of delayed graft function (DGF) after renal transplantation. Methods Totally 57 patients with DGF after renal transplantation who were diagnosed by pathological biopsy were also diagnosed by TCM doctors to obtain TCM syndromes. And the pathological diagnoses were compared with the distribution of TCM syndromes to discuss the relationship between them. Results All the patients were classified into four TCM syndromes:spleen-kidney qi deficiency, liver-kidney yin deficiency, qi-stagnation and blood stasis, and deficiency of both qi and yin. The results of pathological biopsy were as follows:acute tubular necrosis, calcineurin inhibitor toxicity and acute rejection. Quantitative corresponding relation was found between the pathological diagnoses and the TCM syndromes. Conclusion There are inner links between pathological diagnosis and TCM syndromes of DGF, which can be references for diagnosis and treatment of TCM syndrome differentiation.

BACKGROUND:Mimics software is a three-dimensional (3D) image processing and editing tool based on CT scan data. Mimics software can rebuild the data and images gotten in CT, MRI and ultrasound scans into 3D images and display on the computer screen so as to help clinicians understand the type of fracture and the relationship of the 3D structure of the surrounding tissue and to provide a great help in the development of orthopedics operation. OBJECTIVE:To explore the application effect of Mimics software 3D reconstruction on perioperative period of Pilon fracture. METHODS:This study selected 61 cases of Pilon fracture, who received the surgery in the Zhongshan City Xiaolan People’s Hospital from September 2008 to September 2013, as research objects. They were randomly divided into 3D group and control group in accordance with the time of admission. Al patients underwent anterioposterior and lateral X-ray film examination and multi-slice spiral CT scan. Patients in the control group received internal fixation according to above examination results. Patients of the 3D group, on the base of those of the control group, were subjected to internal fixation after three-dimensional entity reconstruction by using Mimics V 10.0 software. Operation time and functional curative effect in the postoperative folow-up were compared between the two groups. RESULTS AND CONCLUSION:The operation time was significantly less in the 3D group than in the control group (P < 0.05). The number of patients with excelent 6-month functional curative effect was more, and the number of patients with poor effect was less in the 3D group than in the control group. The 6-month functional curative effect was better in the 3D group than in the control group (P < 0.05). These results showed that the application of Mimics software 3D reconstruction to the perioperative period of Pilon fractures can give comprehensive assessment of the situation of fracture, optimize and improve the preoperative plan and reduce the risk of surgery, and promote the successful completion of internal fixation.

Objective To investigate the effects of social support intervention on anxiety and depression of pulmonary hypertension(PH)patients,then provide a scientific basis for nursing of patients with pulmonary hypertension.Methods The general condition of PH questionnaire,self-rating anxiety scale (SAS),self-rating depression scale(SDS),social support rating scale(SSRS)were distributed to 131 patients with PH.Then make statistical analysis of patients'anxiety,depression and social support conditions.Results The score of anxiety and depression psychological conditions of patients with pulmonary hypertension was significantly higher than normal population,the difference wag statistically significant.Among 131 patients,16 patients with anxiety,accounting for 12.21% ;21 cases of patients with depression,accounting for 16.03% .28 patients at a high level of social support,92 patients at a medium level of social support,11 patients at a low level of social support,a total of 91.60% of the patients in the middle and higher levels of social support.Anxiety and depression scores had significant negative correlation with social support,objective support points and subjective support points.The anxiety,depression difference among different types of pulmonary hypertension was statistically significant.The difference of anxiety and depression scores between patients with idiopathic pulmonary arterial hypertension and patients with pulmonary hyper tension caused by congenital heart disease were significant.The depression scores between pulmonary hy pertension caused by pulmonary veno-occlusive disease and congenital heart disease were significantly different.Conclusions When nurses care pulmonary hypertension patients.those with different types of PH should be given targeted social support.Attention should be paid to transfer the source of social support to help them adopt a positive attitude to face the diseabe,then improve the treatment and care compliance of patients.

Aim To establish the pharmacokinetic-pharmacodynamic(PK-PD) modeling to characterize the antipyretic effects of coptisine, an active component in coptis chinensis on rats.Methods Nine healthy male Sprague-Dawley(SD) rats were randomly divided into three groups, each with three.The rats in the first group were injected intravenously with lipopolysaccharide(LPS,100 μg·kg-1) alone.The second and third group rats were given coptisine high-dose(3.87 mg·kg-1) and coptisine low-dose(1.93 mg·kg-1) by tail vein injection at 30 min after LPS injection, respectively.Body temperature was measured at different time points, and blood samples from tail vein were collected simultaneously.The blood concentration of coptisine was determined by ultra performance liquid chromatography.Monolix software was used to model PK-PD of coptisine mean plasma concentration and temperature effects,by population computation with non-covariates.Besides.the model with advantage was selected by the fitting goodness.Results Coptisine could inhibit body temperature of endotoxin-induced fever in rats significantly.Two-compartment linear elimination model was used to describe the final PK model.Gaussian function, an input function of body temperature changes, which was used to depict PD model, the PK and PD models were connected by the Emax model.At last, the final model was fitted better;the fitting results indicated that the EC50 of antipyretic effect of coptisine was 89.7 μg·L-1, and the Emax was 1.88℃.Conclusions Coptisine has a powerful anti-pyretic effect on endotoxin-induced pyrexia of rats with high potency, Low in vivo distribution and quick clearance.
