Objective To study the expression of pericyte and the association between pericyte and angiogenesis in the endometriosis. Methods the endometriosis group is consisted of 20 ectopic endometrium, 20 eutopic endometrium dur-ing proliferation phase, 20 eutopic endometrium during secretory phase of patient with endometriosis. The control group (non-endometriosis ) include 20 normal endometrium during proliferation phase and 20 normal endometrium during prolifer-ation phase of women without entometriosis. The histological morphology parameters such as mean density of microvessel (MVD), pericytes number(PN)as well as the average ratio of pericyte to endothelial cells in microvessels were measured by immunohistochemical and morphological assesses. Results The expression of MVD was lower in the normal endometrium and eutopic endometrium compared with it in ectopic endometrium tissue. The difference of the MVD among the different groups was statistical significant (P<0.05). The expression of MVD in secretory phase endometrium was higher than it in proliferative phase endometrium (P<0.05), and it shows no significant difference between eutopic endometrium and normal endometrium. The expression of PN and PN/MVD in ectopic and eutopic endometrium in EMs group were lower than those in control group. However, we also found that the difference of PN and PN/MVD was not statistically significant. Conclusion Pericytes play an important role in angiogenesis of the endometriosis ,and pericyte coverage contribute to maturing of func-tional vasculature of endometriosis.

Objective To investigate the current status and influencing factors of falls self-efficacy among the stroke elderly patients.Methods Totally 170 elderly stroke patients were investigated using the Modified Falls Efficacy Scale (MFES),and they were tested with Berg Balance Scale (BBS) and Time Up and Go Test (TUGT).Results The average score of falls self-efficacy was 108.There were 50.6% elderly stroke patients assigned to the group with low falls self-efficacy.Multiple Logistic regression analysis indicated that impairments of balance and mobility,severe stroke-related disability were the independent influencing factors associated with FOF,which could explain 52.0% of variations.Conclusions Low falls self-efficacy among the stroke elderly patients is a common complaint,nurses and physicians should focus on this problem,interventions combining exercise and education of accidental falls should be taken to improve falls self-efficacy of elderly stroke patients,and prevent falls finally.

Objective To improve hand hygiene compliance among healthcare workers (HCWs)in a stomatological hos-pital,and effectively reduce healthcare-associated infection(HAI)rate.Methods According to WHO hand hygiene guide-line and implementation scheme of hand hygiene,a systemic and step by step hand hygiene promotion plan was formulated, the plan was divided into five steps:full alert,baseline investigation,improvement,tracking,and retrospective analysis. Hand hygiene compliance among HCWs before and after the promotion of activities was analyzed and compared. Results Through hand hygiene promotion activities,the questionnaires showed that average score of knowledge about hand hygiene among HCWs enhanced from 58.33 to 77.40 (increased by 32.69%);the average hand hygiene compliance rate increased from 24.28%(59/243)to 49.81%(133/267),the difference was significant(χ2 =35.331,P =0.000);hand hy-giene status at five moments for hand hygiene improved markedly.Conclusion Hand hygiene promotion has a significant in-fluence in hand hygiene among HCWs in this stomatological hospital.

Objective To evaluate the values of integrated backscatterr (IBS) and dobutamine stress echo- cardiography (DSE) in the diagnosis of coronary artery disease(CAD).Methods Thirty-one suspected CAD patients received DSE and IBS analysis before selective coronary angiography(SCA).Using SCA results as the golden standard of the diagnosis,the diagnostic sensitivity(Se),specificity(Sp),and accuracy rate (Ac) of conventional eye-view and DSE-cyclic variation integrated backscatter (CVIB) were compared. Results The CVIB of myocardial segments perfused by stenotic coronary artery was smaller than that of segments perfused by patent coronary artery during high dose of DSE. For conventional DSE eye-view method, the Se,Sp,and Ac were 80%,72% and 77%, while that of DSE-CVIB were 90%,72% and 83%, respectively. Conclusion IBS is a valuable method in assessing the myocardial wall motion in DSE, and the combination of the two methods can improve the diagnostic accuracy rate of CAD.

BACKGROUND: The central position of dendritic cells (DCs) has aroused increasing attention due to strong antigen presentation capability in anti-tumor. However, how to obtain enough functional DCs and reports regarding immunomodulator with low toxicity are few. OBJECTIVE: To investigate the effect of mycobacterium phlei F.U.36 (Utilins) on the proliferation and maturity of DCs derived from human umbilical cord blood in vitro.METHODS: The mononuclear cells were isolated from human umbilical cord blood using Ficoll-Hypaque method and cultured with Utilins, cytokine (human recombinant granulocyte/macrophage colonystimulating factor + recombinant human tumor necrosisfactor-α + recombinant human interleukin-4), or combination cytokine + Utilins, respectively. In addition, cells cultured with RPMI-1640 served as controls. Morphological features and growth of DCs were observed by an inverted microscope. Thephenotype changes of DCs, such CD1a and HLA-DR, were detected by flow cytometry at 9 days after culture. Moreover, DCs were stained by Wright-Giemsa and observed under oil lens. RESULTS AND CONCLUSION: Typical DCs with high expressions of CD1a and HLA-DR were obviously detected in all experimental groups except the control group. The positive rates of CD1a and HLA-DR in the Utilins group were higher than those in the control group, but lower than the cytokine group (P < 0.05). The HLA-DR positive rate of the combination group was higher than that of the cytokine group (P < 0.05). The results revealed that, Utilins can not only promote the proliferation of DCs derived from human umbilical cord blood in vitro but also cooperate with cytokines to induce the maturity of DCs.

Objective:The clinical features, risk factors, and outcomes of coma were analyzed in patients treated with bevacizum-ab combined with chemotherapy This study also aims to increase the awareness on the toxicity of this regimen. Methods:Two cases of coma induced by bevacizumab combined with chemotherapy were reported. Diagnosis, treatment, and relevant literature were reviewed and discussed. Results:Inadequate blood pressure (BP) control was one of the risk factors leading to coma in patients treated with this therapy. The clinical feature of these patients was reversible posterior leukoencephalopathy syndrome (RLPS). Imaging results showed no typical finding. Reinforced supportive treatment including intensive BP control showed satisfactory outcomes. Conclusion:Coma is common in patients treated with bevacizumab combined with chemotherapy. This regimen should be used cautiously in patients with a history of hypertension. BP should be monitored closely and managed promptly during the combination therapy to prevent coma. RLPS-related coma is reversible after appropriate treatment.
