Objective To explore the anti-inflammatory and antipruritic effects of Chushizhiyang ointment in a mouse model. Methods A total of 40 male 8-week-old BALB/c mice were included in this study, and randomly and equally divided into 4 groups. A mouse model of atopic dermatitis (AD)was established in three groups of mice by repeated application of 2,4-dinitroflurobenzene (DNFB)to shaved abdominal skin for sensitization and to shaved dorsal skin for stimulation. After establishment of the AD model, the three groups were topically treated with sodium chloride physiological solution (model group), hydrocortisone cream (hydrocortisone group)and Chushizhiyang ointment (Chushizhiyang group)respectively for 14 consecutive days. The remaining group receiving no sensitization or treatment served as the normal control group. All the mice were sacrificed 12 hours after the final treatment, and the dorsal skin of mice was resected followed by the determination of skin thickness and weight as well as hematoxylin-eosin(HE)staining and toluidine blue staining for the counting of leukocytes and mast cells respectively. Moreover, enzyme-linked immunosorbent assay(ELISA)was performed to measure the levels of interferon-gamma(IFN-γ), tumor necrosis factor alpha(TNF-α), interleukin 4(IL-4)and IL-5 in dorsal skin lesions. In addition, a local skin itching model was induced by histamine phosphate in Hartley guinea pigs, which was used to explore the effect of Chushizhiyang ointment on itch thresholds. Results Compared with the model group, both the Chushizhiyang group and hydrocortisone group showed reduced thickness and weight of dorsal skin in mice (all P < 0.01), numbers of infiltrating lymphocytes and mast cells (all P < 0.01)and levels of IFN-γ, TNF-α, IL-4 and IL-5 in skin lesions (P < 0.05 or 0.01)on day 15 after the start of treatment. The thickness and weight of dorsal skin in mice were significantly decreased in the hydrocortisone group (P <0.01), but experienced no significant changes in the Chushizhiyang group compared with the normal control group. Additionally, Chushizhiyang ointment could significantly increase itch thresholds in guinea pigs induced by histamine phosphate(P < 0.01). Conclusions Chushizhiyang ointment can significantly inhibit DNFB-induced AD in mice, likely by restoring the balance between Th1 and Th2 type cytokines. Moreover, Chushizhiyang ointment could markedly relieve itching induced by histamine phosphate in guinea pigs.

Objective To observe the control effect of heat preservation infusion on incidence of infection after artificial abortion.Methods 168 cases of patients after artificial abortion were randomly divided into the heat preservation infusion group and normal infusion group with 84 cases in each group.The normal infusion group received routine nursing,and was intravenously infused fluid with non heat preservation method,the heat preservation infusion group was intravenously infused constant temperature liquid heated to 37℃.The incidence of infection was observed in two groups of patients after artificial abortion.Results The infection rate of the heat preservation group was significantly less than the normal infusion group.Conclusions Heat preservation infusion can effectively reduce the infection rate after artificial abortion.

Objective To explore the constant temperature infusion on postoperative body temperature and blood coagulation of patients undergoing induced labor.Methods Eighty patients undergoing induced labor were divided into the observation group and the control group randomly:In the former the infusion was done using fluids constantly kept at the temperature of 36℃and in the latter,the infused fluid was kept at room temperature.The two groups were compared in terms of changes of body temperatures,loss of energy,postoperative blood loss and blood coagulation.Results The temperatures of the controls were declined to different extents after infusion and the temperatures of the observation group showed no significant change,but the difference between the two groups was significant(P<0.05).As for the blood coagulation,there were no significant differences in the prothrombin time(PT),activated partial thromboplastin time(APTT)and thrombin time(TT)between the two groups(P>0.05),but the platelet(PLT)and fibrinogen(FIB) content were significantly decreased(P<0.05)and the blood loss of the observation group was significantly less than those in the control group(P<0.05).Conclusion The constant temperature infusion may maintain the temperature and blood coagulation of the patients, reduce blood loss and prevent adverse reactions induced by induced labor.

Objective To investigate the application effect of evidence-based nursing(EBN) in family planning surgery,evaluate the clinical nursing value and improve the quality of clinical nursing.Methods 240 patients who received family planning surgery were randomly divided into the control and the observation groups (120 patients in each group).The conventional nursing model was used in the control group and evidence-based nursing was implemented in the observation group.Self-rating Anxiety Scale(SAS),patients satisfaction(PA) and adverse reaction rate(ARR) were adopted to assess the two groups after different nursing.Results The score of SAS and ARR were significantly lower in the observation group than those in the control group.The patients satisfaction was significantly higher in the observation group than the control group.Conclusions Application of evidence-based nursing plays a significant role in treatment,nursing and life quality improvement of patients with family planning surgery,which is worthy of wide application.

Objective:To investigate the current situation of standardized patient programs and standardized patient educators in China, and to analyze the existing problems in the implementation.Methods:Questionnaire survey was used in this study. The questionnaire was made by Delphi method, and distributed via E-mails or through the internet to medical colleges, affiliated hospitals and general hospitals across the country. Microsoft Office Excel 2016 was used for data reduction and analysis and cartography.Results:A total of 94 medical colleges and hospitals of 27 provinces and municipalities participated in the survey, of which 43.62% had carried out standardized patient programs. The primary factor affecting the program implementation was the lack of standardized patient educators. The existing trainers were mainly clinicians or nurses, and the main way of training the educators was to send them to other universities for learning. A majority of respondents (94.68%) think it is necessary to establish and formulate a unified national certification system for standardized patient educators.Conclusion:The development of standardized patient program is unbalanced in China, and the lack of standardized patient educators has become the primary factor restricting the development. In order to make standardized patients a greater role in medical education, we should encourage different types of personnel to join in the standardized patient training team, to clarify the responsibilities of standardized patient educators, to standardize the process of trainers training, and to establish the certification system of standardized patient educators.
