Objective:To investigate the efficacy of Doula delivery combined with painless delivery and its effects on pregnancy outcome.Methods:A total of 150 parturient women who underwent delivery in the First People's Hospital of Yongkang from June 2019 to June 2020 were included in this study. They were randomly assigned to undergo either conventional delivery (control group, n = 75) or Doula delivery combined with painless delivery (observation group, n = 75). Analgesic effect, mode of delivery, duration of labor and pregnancy outcome as well as mood score before and after intervention were compared between the two groups. Results:Total analgesia-effective rate in the observation group was significantly higher than that in the control group [100.00% (75/75) vs. 65.33% (49/75), χ2 = 31.45, P < 0.05]. Vaginal delivery rate in the observation group was significantly higher than that in the control group [84.00% (63/75) vs. 66.67% (50/75), χ2 = 6.60, P < 0.05]. The length of the first stage of labor, the second stage of labor, the third stage of labor and total labor length in the observation group were (398.42 ± 35.41) minutes, (43.65 ± 5.78) minutes, (8.36 ± 1.08) minutes and (450.87 ± 37.98) minutes, which were significantly shorter than those in the control group [(543.21 ± 47.87) minutes, (76.73 ± 16.56) minutes, (9.76 ± 1.23) minutes, (629.34 ± 45.26) minutes, t = 21.05, 16.33, 7.40, 26.15, all P < 0.05]. The incidence of neonatal asphyxia, fetal distress and postpartum hemorrhage in the observation group were [1.33% (1/75), 2.67% (2/75) and 2.67% (2/75), respectively, which were significantly lower than those in the control group [13.33% (10/75), 17.33% (13/75), 18.67% (14/75), χ2 = 7.94, 8.96, 10.07, all P < 0.05]. Self-rating Anxiety Scale score and Self-Rating Depression Scale score in the observation group were (43.25 ± 4.28) points and (40.28 ± 3.45) points, which were significantly lower than those in the control group [(52.12 ± 3.95) points, (47.79 ± 3.72) points, t = 13.18, 12.81, both P < 0.05). Conclusion:Doula delivery combined with painless delivery can relieve women's emotional changes, alleviate pain, shorten labor duration, and improve pregnancy outcomes.

Objective To optimize the method of primary culture for human amniotic epithelial cells (AECs) and detect the expression of hepatocelluar specific proteins in AECs. Methods AECs were obtained by collagenase and trypsin digestion method. 10,20,40 ng/mL epidermal growth factor (EGF) and 10 ng/mL basic fibroblast growth factor were added separately to the culture media,inverted microscope was used to observe the cell growth and proliferation,and the optimal condition for primary culture of AECs was obtained. The primary cells cultured without growth factors were served as controls. The expression of hepatocelluar specific proteins such as albumin,cytokeratin-18 (CK-18),alpha-1 antitrypsin (AAT) and alpha-1 foetoprotein (AFP) in cultured cells and histological sections were detected by immunohistochemical staining. Results The AECs available were relatively pure,with only a few mesenchymal cells. EGF of 10 ng/mL was chosen as an ingredient of culture medium as the growth and proliferation of AECs significantly accelerated with 10 ng/mL EGF. The expression of albumin,CK-18,AAT and AFP was detected in amnion tissues and AECs cultured in vitro. Conclusion Collagenase and trypsin digestion method and culture medium with 10 ng/mL EGF are favourable conditions for primary culture of AECs. Hepatocelluar specific proteins are expressed in human amnion tissues and AECs cultured in vitro,indicating that AECs have some characteristics of hepatocytes.

As a technology platform for proteome research, suspension array technology has just started, but it is another way to open up a new research model, especially m the study of TCM syndrome.the accumulation of protein will be integrated to select specific, sensitive, universal syndrome protein expression profiles for the standard syndrome to provide more effective micro-data,it is possible to make objective and quantitative differentiation of syndromes.

Functional magnetic resonance imaging(fMRI) is a very powerful method to understand the mechanism of brain function with non-invasive localization, high spatial and temporal resolution. The essential fMRI technique is blood oxygen level dependent (BOLD-fMRI). Basic principles and methodological applications of BOLD-fMRI are reviewed in this paper.

Referring to relative documents,it reviews the developments on the relation between IIS and gastro-intestinal hormones(gastrin,gallbladder bile-syst contractin,active vessel intestinal peptide and article P),and sums up the relativity study on the relativity between different TCM types of IIS and gastro-intestinal hormones secretion level.

Considering the fact that the critical medical education was relatively backward, and the basic medical education was out of touch with clinical practice, this study, combined with the complexity, uncertainty and comprehensiveness of critical care medicine , puts forward the concept of critical care medicine holistic medicine in clinical practice. We try a patient-oriented approach in clinical practice, focusing on the whole, focusing on the interaction relationship among patient and disease and its pathologi-cal and physiology processes, development, complication and prognosis of disease, instead of paying atten-tion only to disease or single organ itself. The purpose of patient-based learning is trying to train medical students and junior residents to form good clinical thinking ability and decision-making ability.

This paper probes into the scientific research management at a teaching hospital,where three responsibilities are required in clinical service,medical education and research.The staffs＇ need for scientific research is discussed base on Maslow＇s need-hierarchy theory.An incentive system is also proposed for research and professional development of the hospital.

Self-forgiveness is a component of forgiveness trait. It’s not only the response to the wrongdoing,but also a character of the individual. It can help the subjects dismiss negative emotion and inner conflict,help the subjects reduce depression and anxiety,and improve their sociality and life-satisfaction. The author has reviewed relative articles in recent years with the emphasis on exploring the definition,the factors of self-forgiveness and the relation between self-forgiveness and mental health.
