Objective To explore the expressions of matrix metalloproteinases-1(MMP-1) and tissue inhibitor of metalloproteinase-1(TIMP-1) in sternomastoid muscle and explore the pathogenesis of sternomastoid muscle fibrosis in congenital fibra muscular torticollis in children.Methods The hyperplastic state of collagen fiber were determine by Masson collagen stainning method and muscular torticollis and fibra torticollis was differed,obtained 22 cases of the fibra torticollis group.Immunohistochemical method was used to determine the expression of MMP-1 and TIMP-1 in sternomastoid muscle of fibra torticollis and compared them with 6 cases of control group.Results By the immunohistochemical method,the expression of MMP-1 in the experiment group significantly decreased than that in control group(P0.05).Conclusion In congenital fibra torticollis,the sternomastoid muscle fibrosis is related to the decrease of MMP-1.

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time. The body weight, sucrose preference, crossings and rearings in open-field tests were evaluated and the urine was collected simultaneously. The metabonomic profiles of rats' urine were analyzed by NMR and potential biomarkers were searched by multivariate statistical analysis. The results showed that administration of FFCGF significantly decreasing the immobility time in FST and TST and improving rats' body weight, sucrose preference, crossings and rearings in CUMS, which were indication that the anti-depressant effect of FFCGF was abvious. Significant differences in the metabolic profile of the CUMS treated group and the control group were observed, which were consistent with the results of behavioral tests. Decreased levels of acetic acid, succinic acid, 2-oxidation glutaric acid and citric acid and increased glycine and pyruvic acid in urine were significantly affected by the CUMS procedure and the 6 biomarkers were reversed evidently after administration of FFCGF. These changes were suggestion that the anti-depressant mechanism of FFCGF was associated with energy metabolism, lipid metabolism and amino acid metabolism.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.

METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.

RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).

CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.

Objective To evaluate the effect of mind mapping on adverse effects caused by medication via patient control alagesia pump(PCA).Methods One hundred and seventy-nine patients with PCA pump after operation were divided into control group(n=90)and observation group(n=89)according to the admission time.The observation group was nursed with mind mapping and the control group with routine method. The incidences of adverse effects caused by medication via PCA pump were compared between the two groups.Result The incidences of adverse effect in the observation group and the control group were 19.1%and 32.2%respectively,with statistical significance(P<0.05).Conclusion Nursing with mind mapping for medication via PAC pump can improve nurses’clinical ability in observation and nursing and therefore effectively prevent and deal with adverse effect caused by medication via PCA pump to relieve patients’pain and improve nursing quality.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

OBJECTIVETo analyze the reliability and validity of the Fatigue Self-assessment Scale (FSAS).

METHODSThe scale was applied among the participants assigned to 4 groups, the differences in types, degrees and characteristics of fatigue of them were compared, and the reliability and constitutional validity of ESAS were assessed by internal consistency analysis, exploratory factor analysis and confirmatory factor analysis using the statistical software of SPSS and LISREL.

RESULTSStatistical differences of types, degrees and characteristics of fatigue presented in the participants of the 4 groups. The Cronbach's alpha of various factors in the scale were 0.772-0.908; the indexes for the section of assessing type, and degree of fatigue were RMSEA=0.065, NNFI=0.95, CFI=0.96; and those for the section of assessing characteristics of fatigue were: RMSEA=0.10, NNFI=0.93, CFI=0.96.

CONCLUSIONThe FSAS has good differentiability, reliability and constitutional validity for assessing the type, degree and characteristics of fatigue in various populations. In order to explore the relationship of TCM syndrome patterns with the type, degree and characteristics of fatigue, its future application for evaluation of fatigue and intervention effect of anti-fatigue should be combined with TCM syndrome differentiation.
