Objective To explore the clinical psychological intervention and edaravone in the treatment of acute cerebral infarction.Methods In the period from January 2016 to December 2016, 335 patients were treated with acute cerebral infarction in our hospital, and these patients were randomly divided into two groups: control group and observation group, control group A total of 168 cases, the observation group of patients a total of 167 cases. First, the control group of patients using conventional medical treatment for treatment, the observation group of patients will need in the conventional medical treatment based on the increase in the use of edaravone intravenous infusion. And then the two groups of patients are using clinical psychological intervention care for nursing work. Through the follow-up approach, the two groups of patients to observe the effect of treatment, comparison, need to rely on daily living ability (ADL) and the Chinese Stroke Scale (CSS) two assessment indicators to evaluate the patient's treatment.Results Before treatment, the daily living ability (ADL) and the Chinese stroke scale (CSS) two evaluation indicators score, the difference was not statistically significant; After treatment, the observation group of patients with daily living ability (ADL) and the Chinese stroke scale (CSS) two evaluation indicators were significantly better than the corresponding value of the control group, the difference between the two groups statistically significant (P<0.05). The total effective rate was 94.61％ in the observation group, the total treatment effective rate was 72.02％of control group, the therapeutic effect of the observation group was better than that of the control group (P<0.05).Conclusion Patients with acute cerebral infarction on the basis of the use of conventional medical treatment on the basis of increased use of edaravone intravenous infusion, compared to conventional medical treatment is better, while after treatment for patients with clinical psychological intervention Care for the nursing work, the improvement of the treatment effect has a positive effect, help to improve the patient's daily life ability.

Objective To explore the inhibitory mechanism of Imatinib mesylate on pulmonary fibrosis induced by bleomycin in mice.Methods A total of 120 C57BL/6 mice were randomly divided into four groups,ie, a control group, a model group, a dexamethasone group, and an Imatinib group.The model of pulmonary fibrosis was established by a single intratracheal instillation of bleomycin in the rats.Then dexamethasone or Imatinib were given intraperitoneally respectively.On day 7,14,21 after the treatment, 10 mice of each group were sacrificed respectively.The expressions of TGF-β1 and α-SMA in lung tissue were analyzed by immunohistochemistry.The mRNA expression of TGF-β1 was measured by RT-PCR.Results The expressions of TGF-β1 and α-SMA in lung tissue at each time point were significantly increased in the model group compared with the control group.And the expressions were obviously decreased in the dexamethasone group and the lmatinib group compared with the model group, with no significant differences between the two treatment groups.The expression of TGF-β1 was positively correlated with the α-SMA expression (r = 0.251, P < 0.05).Conclusion The inhibitory effect of Imatinib on pulmonary fibrosis may be related to the inhibition of TGF-β1 and α-SMA expressions.

Objective To observe the dynamic changes of adrenomedulin(ADM) and calcitonin-gene-relat-ed peptide(CGRP) at different time before,during and after laparoscopic operation for treating CO2 pneumoperitone-urn. Methods 47 cases undergoing laparoscopic operation in our hospital were selected. Plasma ADM and CGRP levels were determined by RIA before anesthesia(T0),10 min before (T1) and 10 min (T2) ,30 min (T3),60 min (T4),and 30 min (TS) after CO2 pneumoperitoneum was treated. Results There was statistical significance in ADM and CGRP level at the different time points before and after CO2 pneumoperitoneum (F=9.686 and 49.804, P<0.01). There was no significance in ADM and CGRP level at TO and T1 (P>0.05);ADM level would decrease at T2 (P<0.05) but CGRP level decrease slowly with no remarkable change as compared with that before CO2 pneumoperitoneum(P>0.05). With time going on, ADM and CGRP level at T3 and T4 was remarkably lower than that at T1 (P<0.01);ADM and CGRP level at T5 would come to that at T1. Conclusions CO2 pneumoperitoneum during laparoscopic operation is the major factor causing decreased ADM and CGRP level;The decrease of ADM and CGRP level will influence the cardiac endocrine function,so CO2 pneumoperitoneum operation should be taken seri-ously when the patients have heart disease and cryptorrhea.

Objective To discuss the relationship between and value of Leptin with disorder of lipid metabolism in gestational diabetes mellitus. Method Research objects are divided into three groups including GDM group, normal glucose tolerance group (NGT group), normal non-pregnant group. Blood lipid, fasting blood glucose, fasting insulin, serum leptin and placental leptin levels were detected and HOMA-IR was calculated. Result (1) Serum leptin, TC, TG, placental leptin and HOMA-IR in GDM group were higher than those of NGT group and TC, serum leptin and HOMA-IR of NGT group were higher than those of control group. There were statistical significances (P<0.05). (2)Serum leptin levels were positively correlated with BMI, HOMA-IR, TC and TG respectively (r = 0.593, 0.688, 0.722, 0.492 respectively, P < 0.05). Conclusion Leptin may cause lipid metabolism disorders, and together they participate in the pathogenesis of GDM. Maternal serum leptin level is expected to become an observation index of GDM.

Cell culture technology is the most commonly used method in the in vitro experiments at present. However, monolayer cell culture technology has been unable to meet the demand of the researchers. This is because that monolayer cell culture cannot mimic the cellular environment in which multiple cells interact with each other in the body. We cannot discuss the relationship of many cells, because we do not know the relationship between cells through a single kind of cell. So cell co-culture medicine arises at the historic moment for the demand. With the development of research method in recent years, cell co-culture method also has been improved in practice: from direct contact co-cultures to indirect contact co-cultures, from two-dimensional co-cultures to three-dimensional co-cultures. Cell co-culture method is closer to the human body. It is also more advantageous to study the interaction among cells. Nowadays, there are more researchers tend to select this method to study the physiological and pathological in vitro model, tissue engineering, and cell differentiation research. At the same time, it has become the focus of drug research and development, drug analysis, mechanism of drug action, and drug targets. This article will review the studies of cell co-culture method, summarize advantages and disadvantages of various methods, so as to promote improvement of cell culture methods, to build cells co-culture system that more close to human body, and build the in vitro model that simulate internal circulation of human body further.
