Six compouuds were isolated for the fitst time from Spiraca mongolica Maxim. (Rosaceae by means of chemical and spectral analyslsand comparison with data of literature or authentie samples, 5 of them were identified as ?-sitosterol(Ⅰ), betulin(Ⅱ), betulinic acid (Ⅲ),betuliuic acid 3, 5-dihydroxyl-cinuamate(Ⅳ) and daucosterol(Ⅵ).

Objective To observe the role of the health education model in pain self- efficacy for patients with cancer pain. Methods Sixty- four patients suffering from cancer pain were enrolled into the study and self- contrast experiment was made on each patient. The health education model was set up and health education for each patient with cancer pain was implemented. The pain, self- efficacy, cancer pain knowledge before and after the intervention were observed by Numerical Rating Scale (NRS),Chronic Pain Self- efficacy Scale(CPSS) and Cancer Pain Knowledge Questionnaire. Results NRS score were (5.38 ±0.19) points and (1.05 ± 0.11) points before and after the intervention, and there was significant difference (t =25.288, P = 0.000). Before intervention, pain management self- efficacy, physical function self- efficacy, symptom coping self- efficacy of CPSS scores were (10.38 ±0.37) , (20.97±0.81) , (16.86 ± 0.49) points, while after the intervention, the scores were (19.31± 0.30) , (33.25 ± 0.60) , (29.75 ±0.51) points, there were significant differences ( t = -33.225, -18.236, -18.235, all P = 0.000). Before and after the intervention, the answer rate of Cancer Pain Knowledge Questionnaire was 50.00%(32/64) and 87.50%(56/64), there was significant difference( χ2=20.51, P < 0.01). Conclusions To set up the health education model and implement health education for each patient with cancer pain can improve the patient′s pain management and enhance self-efficacy.

Objective To observe the clinical effect of peroutaneous ethanol injection therapy (PEIT) of parathyroid gland guided by color ultrasound on dialysis patients with secondary hyperparathy-roidism. Methods Percutaneons ethanol injection therapy (PELT) was used for seven patients who suf-fered from secondary hyperparathyroidism, and systemic perioperative nursing care and relative health edu-cation were applied. Results All patients had obtained successful operation without any operative sud-denness or associated complications,Patients" serious scratching and bone ache was obviously relieved.Conclusions Treatment with PEIT and effective nursing to patients suffered from secondary hyper-parathyroidism can reduce the complications, and than improve the quality of live for patients.

Aim To establish the rat model of Spleen-Qi deficiency, analyse the metabolic pathways and investigate the connection between the changed urinary metabolites and Spleen-Qi deficiency, in order to explore the potential mechanisms of Spleen-Qi deficiency.Methods With the binding methods of diarrhea induced by bitter and cold, abnormal of starvation and excessive tiredness, the rat Spleen-Qi deficiency model was established.Then the activity of creatine phosphokinase(CPK) was detected.The endogenous metabolites in the urine were detected by NMR, and the data were analyzed with multivariate and statistical methods.Then the metabolites were selected that could be clearly distinct in the two groups with the fold change value(>1.2) and the P<0.05 of Student′s t-test.Both the pathway analysis and enrichment analysis were performed with Metabo Analyst 3.0.Results Compared with the normal rats, the activity of CPK decreased significantly in model rats(P<0.05).A significant separation appeared in the principal components analysis(PCA) score plot when the control group and the model group were compared, indicating that the Spleen-Qi deficiency model was successfully duplicated.The 33 differential metabolites, which mainly involved in the metabolic pathways, were distinguished from the comparision of Spleen-Qi deficiency model group and control group.The metabolic pathways was related to energy metabolism, amino acid metabolism, nucleotide metabolism and disturbance of gut microbes.Conclusions The main energy metabolic pathways (tricarboxylic acid cycle, glycolysis and liquid oxidation) may be disturbed in Spleen-Qi deficiency rats.The energy supply function is suppressed, which leads to the fatigue and weight loss in rats.

The number of investigator initiated research (IIR) is increasing. But the recognition and management of IIR in China is still in its infancy, and there is a lack of specific and operable guidance for the implementation process. Based on our practical experiences, previous literature reports, and current policy regulations, the authors took prospective IIR as an example to summarize the implementation process of IIR into 14 steps, which are as the following: study initiation, ethical review, study registration, study filing, case report form design, database establishment, standard operating procedure making, investigator training, informed consent, data collection, data entry, data verification, data locking and data archiving.
