Objective In order to study the structure-activity relationship of oridonin,Some derivatives of oridonin were synthesized and their cytotoxicity activity was evaluated.Methods Oridonin (Ⅰ) was isolated and purified by silica gel column chromatography.The derivatives were synthesized from oridonin through oxidation and acylation.All compounds were confirmed by spectrum analyses and their cytotoxicity was evaluated by MTT method.Results Six compounds were obtained and identified as: 14-acetyl-oridonin(Ⅱ),1,14-diacetyl-oridonin(Ⅲ),14-p-tolylsulfonyl-oridonin(Ⅳ),1-oxo-oridonin(Ⅴ),14-acetyl-1-oxo-oridonin(Ⅵ),14-p-tolylsulfonyl-1-oxo-oridonin(Ⅶ).Among them compounds Ⅳ,Ⅵ,and Ⅶ were new compounds.Five compounds showed better cytotoxicity than oridonin.Conclusion The cytotoxicity of 1oxo oridonin derivatives is first evaluated and shows the stronger cytotoxicity than oridonin.

Naive and chronically infected C57BL/6 mice were challenged percutaneously over the ear pinna with Schistosoma japonicum cercariae. After 15 hours, the number of EOS increased significantly in the skin of chronically infected mice. Inflammatory cells aggre-gated in the vicinity of schisto.somula or entrapped intact and disintegrated schistosomula, forming granulocytic micro-abscesses in both groups. Ultrastructure studies revealed that flattened EOS tightly attached to the schistosomulum surface and degranulated. Local tegument damage occurred in the area of attacbment. NEU adherence did not seem to be as intimate as EOS, and degranulation was not seen. The tegument of the attached schis-tosoniulum remained normal. The result suggested that EOS appeared to be the efficient killer cell against skin phase schistosomula of S. japonicum (Figs. 1-6).

Objective To analyze the effect and safety of budesonide combined with psychological intervention on the treatment of the children with bronchitis. Methods 60 children with capillary bronchiolitis in Enze hospital from June 2014 to May 2016 were randomLy divided into the control group and the experimental group, 30 cases in each group. The control group were received conventional treatment, such as, anti-inflammatory, antiviral, bronchodilator and oxygen inhalation. At this basis, the experimental group were given budesonide aerosol inhalation combined with psychological intervention. The clinical therapeutic effect in the two groups were compared. Results The cough stopping time, hospitalization time and the time of lung wheezing rale in the experimental group were significantly shorter than those in the control group, and the adverse reactions in the experimental group were significantly lower than those in the control group, and the difference between the 2 groups was statistically significant(P<0.05). Conclusion The children with capillary bronchiolitis patients were given budesonide inhalation combined with psychological intervention on the basis of routine therapy, which can effectively improve the clinical symptoms, improve the curative effect, low incidence of adverse reactions, shorten the treatment time, which is worthy of clinical application.

Objective To study the therapeutic effect of Fumaderm in Freund' complete adjuvant-induced arthritis (AIA) in Spraque-Dawley rats. Methods Adjuvant-induced arthritis (AIA) was established by intradermal injection of 0.1 mL of Freund' complete adjuvant (CFA) in the palmar surface of the right hindpaw and Fumaderm was delivered by oral gavage for 28 days. After CFA injection, the edema of the hindpaw was determined every two days. On 28 days after CFA injection, the lymphocyte subsets of peripheral blood and the cytokines were determined by flow cytometry, meanwhile the histopathological examination of ankle-joints of the animals was performed. Results Fumaderm had a significant therapeutic effect on AIA. The hindpaw swelling was reduced significantly in a dose-dependent manner. The ratio of peripheral blood T lymphocytes was improved obviously. Multiparameter cytokine analysis from peripheral blood CD4+ T cells showed a decrease of proinflammatory cytokines and an increase of anti-inflammatory cytokines in Fumaderm treated animals. A strongly reduced inflammatory response in the joint synovium was observed. Conclusion Fumaderm has potential anti-inflammatory effects on AIA rats. Further investigation is needed to elucidate the molecular mechanism involved in the clinical effect observed in the AIA model.

An analysis of the fundamental concepts for public hospital reform further defined public hospitals and other hospitals,business and non-business in nature,public benefits and welfare,as well as public benefits and profit-oriented hospitals.These distinctions can help reformers of public hospitals clarify their concepts,make clear the purpose and direction of the public hospitals reform,so as to speed up the reform with theory support.

This paper studied the development stages in terms of the public nature of public hospitals in China and analyzed the causes for their weakened public benefits.It proposed the principle of government guidance,achieving government purchasing of healthcare services as the roadmap,as well as building and improving the service purchasing system,performance appraisal system,and payment review system along with supervision system.These measures are designed to make public hospitals in their public benefit nature with scientific system design,powerful institutional guarantee,and efficient execution strategies.

Objective To investigate the relationship between cognitive function and emotional status in functional constipation patients.Methods Thirty-five functional constipation patients (the functional constipation group) and 24 healthy controls (the HCs) were enrolled in an event-related potential (ERP),behavior and electroeneephalogram study while performing an oddball auditory task.Response time,accuracy,latency and P300 amplitude were compared between the two groups.The Hamilton depression rating scale (HAMD-17),Hamilton anxiety scale (HAMA),symptom check list-90 (SCL-90) and Eysenck personality questionnaire (EPQ) were administered prior to the oddball task.Results The average HAMD-17,HAM A and SCL-90 (the somatization,obsessive-compulsive disorder,depression,anxiety and psychosis dimensions) scores of the functional constipation group differed significantly from those of the HCs.The intro-extraversion and neurosis dimensions of the EPQ were also significantly different.There was no significant difference in response time or latency between the two groups.The ERP results showed that the P300 amplitudes at the F3 and F7 sites were significantly different between the functional constipation group and the HCs.But there was no significant difference in P300 latencies at F3 or F7 between the two groups.Conclusions The findings suggest that patients with functional constipation are more susceptible to depression and anxiety,as well as somatization,obsessive-compulsive tendencies and other neurotic personality characteristics.Patients may employ psychological defense mechanisms to avoid the depression and anxiety.The ERP results imply there may be the implicit cognitive dysfunction with emotion in patients with functional constipation.

Objective To investigate the change and clinical significance of serum procalcitonin (PCT) level in patients with community-acquired pneumonia (CAP).Methods One hundred and forty-five CAP patients were enrolled.Serum PCT level was measured by immunofluorescent antibody staining method.CURB-65 score and pneumonia severity index (PSI) score were used to evaluate the severity of the patients with CAP.Correlations between PCT and blood white blood cell (WBC) count,serum C-reactive protein (CRP),PSI score,CURB-65 score,hospitalization duration and mortality were analyzed with Pearson correlation analysis,Logistic regression analysis and so on.Results Serum PCT in patients with CAP showed positively correlated with CURB-65 score and PSI score (r =0.606,0.943,P＜ 0.01 ),and serum PCT was also positively correlated with age,serum CRP and hospitalization duration (r =0.753,0.233,0.281,P ＜0.01),but it wasn't correlated with blood WBC count (r =0.152,P ＞0.05).Logistic regression analysis showed that each increment of 1 μ g/L for serum PCT would increase 2.828-fold for the risk of death in CAP patients.Conclusions Serum PCT predicts the sensitivity and specificity of CAP with a similar prognostic accuracy with CURB-65 score and PSI score.Serum PCT in patients with CAP correlates with hospitalization duration and mortality.Therefore,it is a promising prognostic marker to evaluate the severity and outcome of CAP.It may serve as a useful marker for clinicians to evaluate the severity and prognosis of CAP.

Objective To study the effect of rhodiola crenulata compound on serum corticosterone and myocardial glucocorticoid receptor ( GR) in rats exposed high sustained +Gz.Methods Seventy-two healthy SD rats were randomly divided into six groups: blank control group, stress control group, +10 Gz stress group and low, medium, high dose drug group, with twelve rats in each.20 mL/kg menstruum was fed to each rat once per day for 14 days.Low, medium and high dose drug group were fed with rhodiola crenulata compound at doses of 0.75 g/kg, 1.5 g/kg and 3.0 g/kg respectively, the other three groups were fed with equal volume saline.Rats were exposed to high +Gz in 15th day.The concentration of corticosterone in the serum of each group rats was detected with ELISA. Western blot was used to detect the expressions of GR in the myocardium of each group rats .Results The content of corticosterone was significantly elevated in +10Gz stress group, while the expression of GR in the myocardium was markedly declined (P <0.01,P <0.05).However, compound preconditioning could decrease concentration of corticosterone in the serum and enhance the expression of GR in the myocardium from rats after +10 Gz exposure. The corticosterone concentration of medium and high dose drug groups was significantly lower and the level of GR expression in the myocardium was significantly higher than that of +10 Gz stress group ( P <0.05 , P <0.01 ) . Conclusion Rhodiola crenulata compound preconditioning could regulate the concentration of corticosterone in the serum and the level of GR expression in the myocardium of the rats exposed +10 Gz, which may be related with its protective effect on high sustained +Gz-induced injury of myocardium.
