Object To isolate and identify the chemical constituents of Saussurea japonica (Thunb.) DC. and to obtain some rules of chemical shift effects on hydroxylation and O-glycosylation. Methods The constituents were isolated by silica gel column chromatography and HPLC (RP-18), and their structures were elucidated through spectroscopic analysis (NMR and FABMS). The rules were obtained by comparison with those of known analogous lignans. Results Three lignan glycosides were isolated and identifiedcas (+)-1-hydroxypinoresinol-4″-?-D-glucopyranoside (Ⅵ), (+)-lariciresinol-4-?-D-glucopyranoside (Ⅷ), and (+)-1-lariciresinol-4′-?-D-glucopyranoside (Ⅸ), as well as the rules for effects of the hydroxy group at C-1 (upshift about ??-4.2) and O-glucosylation (downshift about ??+3.0) on 13CNMR chemical shifts of (+)-pinoresinol and (+)-lariciresinol. Conclusion All these compounds were obtained from the plants of Saussurea DC. for the first time and the rules should be as some important evidences to assign the position of hydroxylation and glycosylation.

rate being 86. 0% cured rate being 60. 0%, remarked-ly higher .than that of the western medication group.100 cases of such patients were randomly divided into 2 groups, each 50 cases. The treating group was treated with spleen-strengthening and damp-removing recipes and medicaments. The cllinical effective

Objective To explore the changes of plasma catecholamines(CA)[including epinephrine(E) and norepinephrine(NE)] and atrial natriuretic peptide(ANP) in children with varying degrees of left ventricular ejection function(LVEF) in chronic heart failure(CHF),and establish natriuretic hormone factors as one of the diagnostic criteria of CHF.Methods Thirty-five patients with CHF and 35 children in good health were enrolled,and the concentration of plasma NE,E,ANP and the LVEF were determined.Results 1.The levels of plasma NE,E and ANP in 35 patients with CHF before treatment were significantly higher than those in control group(Pa

Objective To review the diagnosis and treatment of adrenal myelolipoma(ML).Methods The medical records of 21 patients with adrenal myelolipoma were reviewed.All patients were examined by B-ultrasound,CT and endocrine tests while some were also examined by MRI and 131I-MIBG.Results All patients had undergone resection of adrenal ML.The mean diameter of tumors was 6.7 cm(4.5 cm～12 cm).Pathological examination of all tumors confirmed the diagnosis of adrenal ML.No recurrence was recorded during the follow-up period(1～15years).Conclusion Adrenal ML is a kind of rare,benign tumor and is often incidentally discovered.Its prognosis is generally good.

Emergency departments of hospitals are exposed to risks of patient complaints and disputes, and the emergency department of a stomatology hospital is no exception. Medical disputes at the emergency department of Peking University Stomatology Hospital, as registered at the department of medical affairs of the hospital in the past ten years, are analyzed with statistical processing. The results are used in studying characteristics of medical disputes frequently found in stomatology emergency cases, for references and recommendations on prevention and avoidance of such disputes in future.

BACKGROUND: Cryotherapy of acute soft tissue injury has been widely used in clinical practice.OBJECTIVE: To observe the histological changes and treatment effect of different cryotherapies on the rats' acute damage of soft tissue. METHODS: Neonatal Wistar rats were randomized to normal, model, intermittent cryotherapy and continuous cryotherapy groups. Models of acute damage of soft tissue were established in model, intermittent cryotherapy and continuous cryotherapy groups. In intermittent cryotherapy group, the injury was treated by intermittent cryotherapy with ice bag at 4 °C; in the continuous cryotherapy group, the injury was treated by continuous cryotherapy with ice bag at 4 °C; the model group was not treated. Histological changes were observed at 48 hours. Injury degree was evaluated using injury symptom index.RESULTS AND CONCLUSION: Compared with model group, the scores of injury symptom index and histology were lower, interleukin-1β expression was reduced, and transforming growth factor-β1 (TGF-β1) expression was increased in intermittent cryotherapy and continuous cryotherapy groups (P < 0.05). Compared with intermittent cryotherapy group, the scores of injury symptom index and histology were reduced (P < 0.05), interleukin-1β expression was reduced (P < 0.05), and TGF-β1 expression was increased in continuous cryotherapy group (P < 0.05). Results demonstrated that cryotherapy can cure the acute damage of soft tissue by reducing interleukin-1β expression and raising TGF-β1 expression. Continuous cryotherapy is superior over intermittent cryotherapy.

Objective To investigate the expression and significance of survivin and CD44v6 in non-small cell lung cancer (NSCLC) and their correlation. Methods SP immunohistochemical technique was used to detect the expression of survivin and CD44V6 protein in 53 cases of NSCLC and 13 cases of para-eaneer nor-mal tissues. Results The positive rate of survivin and CD44v6 in NSCLC was 60. 38% and 69. 81% respec-tively,which was higher than that of normal pulmonary tissues adjacent to carcinoma(P <0. 01). The expres-sion of survivin and CD44v6 in NSCLC was related to lymph node metastasis (P < 0. 05), but not to patients' age and gender(P>0.05). The expression of survivin was related to TNM stages and cell differentiation (P <0. 05) ,but not to histology type(P >0. 05). The expression of CD44v6 in squamous carcinoma was significantly higher than that of adenocareinoma (P <0. 05),but the expression of CD44v6 was not related to TNM stages and cell differentiation (P >0. 05). There was no correlation between the expression of survivin and C1)44v6 (r = -0. 058, P >0. 05). Conclusion Survivin might be used to evaluate NSCLC development;CD44v6 might be used for the differential diagnosis of squamous carcinoma in NSCLC;both of them might be helpful to predict the metastasis of NSCLC. They might be two independent events in the process of NSCLC genesis and develop-ment.

Objective To discuss the opportunity of hemilateral craniotomy in treatment of a large area combined middle cerebral artery (MCA) infarction.Methods Thirty-two patients with a large area combined MCA infarction were performed by hemilateral craniotomy.Initial clinical presentation was evaluated by the Glasgow coma scale(GCS).All survivors were assessed three months after surgical decompression according to Barthel index(BI).The effects of pre-hemia decompressive surgery(before any signs of cerebral hernia,based on clinical status and CT or DWI findings)versus post-hernia surgery (after signs of hernia) on mortality,functional outcome.Results In 18 patients with pre-hernia decompressive surgery,3 patients (16.7%)were dead and average BI was (66.94±7.75)scores.The mortality was 57.1%(8/14)and average BI was (38.43±9.82)scores of post-hernia surgery with 3 cases severe aphasia.Conclusion Hemilateral craniotamy is performed before occurrence of cerebral hernia may decrease the mortality and improve outcome in these patients.

Objective To study the importance of statins in the prevention and treatment of coronary heart disease.Methods167 cases of coronary heart disease in our hospital from December 2013 to November 2014 were chosen as the research object, patients were given different statins such as atorvastatin, rosuvastatin and simvastatin treatment, and total cholesterol(TC),triglyceride(TG), low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol (HDL-C)before and after treatment were statistically analyzed.Results3 months after treatment TC,TG,LDL-C,HDL-C were significantly better than before treatment(P< 0.05);3 months after treatment, 6 months and 12 months, the index value has improved, but the differencehad no statistical significance.ConclusionThe use of statins in coronary heart disease has a significant effect,can improve the clinical indicators.
