AIM: To test the effect of ERK1/2 on ischemic preconditioning (IPC) in diabetic rat hearts. METHODS: The diabetic rat model was made with alloxan. After eight weeks, 24 rats were divided into 4 groups: non-diabetic IPC rats (group A); non-diabetic non-IPC rats (group B); diabetic IPC rats (group C); diabetic non-IPC rats (group D). ECGⅡ lead, left ventricular development pressure (LVDP), and first derivative of LVDP ~(?dp/dt_~max ) were recorded. Myocardial phosphorylation of extracellular signal regulated kinases1/2 (ERK1/2) was detected by Western-blotting. RESULTS: (1) The ventricular arrythmia score was significantly lower in group A than that in group C (P

Objective? To investigate the anxiety and depression of pregnant women with spontaneous abortion in the first trimester of pregnancy, and to explore the related influencing factors, so as to provide basis for clinical psychological intervention and treatment. Methods? During August 2015 to February 2016, a total of 70 pregnant women with spontaneous abortions experience and 70 primigravid women at the outpatient department of a ClassⅢ Grade A hospital in Beijing were selected by convenience sampling method. A general questionnaire, Self-rating Anxiety Scale (SAS) and Center for Epidemiologic Studies-Depression Scale (CES-D) were applied in the investigation. Results? There were 8 anxiety cases (11.43%) and 15 depression cases (21.43%) among the 70 pregnant women with spontaneous abortions experience. The scores of SAS and CES-D of the spontaneous abortions group were higher than those of the primigravid group, and the differences were statistically significant (t=2.95,2.51; P＜ 0.05). The age and education level of the pregnant women were positively correlated with scores SAS (P＜0.05). The age, times of spontaneous abortion were positively correlated with scores of CES-D (P＜ 0.05). Conclusions? There is prominent anxiety and depression in the first trimester of re-pregnancy women with spontaneous abortion experience, which may be related to the age, education level and the times of spontaneous abortions. The psychological status of pregnant women with spontaneous abortion should be assessed early and appropriate psychological intervention should be given when necessary.

OBJECTIVE: To investigate the influence of obstructive sleep apnea hypopnea syndrome (OSAHS) on children's growth. METHOD: Fifty-three children diagnosed as OSAHS were included in the treatment group and underwent tonsillectomy or adenoidectomy, and 51 normal children were employed as the control group. Main data monitored by PSG and growth hormone (GH) in children of the treatment group were recorded before and after surgery, in addition, growth hormone, height and weight of children in the treatment group and control group were respectively recorded and compared. RESULT: Height and weight of children with OSAHS before treatment were lower than that of the normal children and the difference was significant (P<0.05). Compared with the data before surgery, oxygen saturation of blood in children of treatment group recorded by PSG increased (P<0.05), while value of other data decreased (P<0.05). Growth hormone in children of the treatment group was lower than that of the control group and the difference between two group was significant (P<0.05), while the content of growth hormone in children of the treatment group elevated after 3 months postoperatively and at this time no difference was found between the two groups. CONCLUSION Children with OSAHS present the symptom of upper airway obstruction, which badly affects sleep quality and results in decreased secretion of growth hormone and finally the height and weight of children is got involved. Timely surgery is necessary to alleviate the symptom.

Objective:To investigate the current situation of kinesiophobia in patients after heart valve replacement surgery and to analyze its influencing factors, and to provide reference for the intervention research of patients with cardiophobia after cardiac valve replacement.Methods:Using cross-sectional survey method and convenient sampling method, 109 patients who underwent cardiac valve replacement surgery in department of cardiothoracic and vascular surgery of Guangxi Zhuang Autonomous Region People′s Hospital from March 2021 to January 2022 were selected as the study subjects. The patients were surveyed with the general questionnaire, Tampa Scale of Kinesiophobia and Visual Analogue Scale.Results:After heart valve replacement, the score of Tampa Scale of Kinesiophobia was (46.90 ± 9.30) points. The score of Visual Analogue Scale was (5.83 ± 1.01) points. The score of Tampa Scale of Kinesiophobia was positively correlated with the score of Visual Analogue Scale ( r=0.46, P<0.01). Multiple linear regression analysis showed that patient′s age, cardiac function level, left ventricular ejection fraction, pain were the main influencing factors of Kinesiophobia ( t values were -2.37-4.34, all P<0.05). Conclusions:Medical staff should understand and accurately assess the status of patient′s kinesiophobia after heart valve replacement surgery, identify high-risk groups of kinesiophobia, and take targeted nursing measures to effectively alleviate postoperative pain, thereby reducing the incidence of kinesiophobia in patients, helping patients to carry out early functional exercise, and prorroting physical recovery.
