ABSTRACT
OBJECTIVE To study the protective effect and possible mechanism of soybean isoflavones against threatened miscarriage rats. METHODS Female mice were selected to promote estrus and mate with male mice. After pregnancy， they were randomly divided into normal group （purified water， i.g.， n＝10）， model group （purified water， i.g.， n＝9）， positive control drug group （progesterone 4 mg/kg， i.m.， n＝9）， low-， medium- and high-dose soybean isoflavone groups （25， 50 and 100 mg/kg， i.g.， n＝10）. Except for the normal group， the rest were given mifepristone+misoprostol on the 8th day of pregnancy to establish threatened miscarriage model， and then given purified water or drugs， once a day， on days 1-7 and 9-12 of pregnancy， respectively. At 14 days of pregnancy， the rates of fetal protection were counted. Serum levels of β-human chorionic gonadotrophin （β-HCG） and progesterone （P） in rats were detected. Pathological and morphological changes in rat placenta and decidua tissues were observed， and the apoptosis indexes of cells were detected； mRNA and protein expressions of factor of apoptosis related （Fas）， factor of apoptosis related ligand （FasL）， proliferating cell nuclear antigen （PCNA） and heparin binding epidermal growth factor （HB-EGF） were determined in placenta tissues， and mRNA and protein expressions of Fas， PCNA and HB-EGF in decidua tissues were detected. RESULTS In the model group， the placental tissues of rats were hyperemia and dilatation， with fewer and irregular blood vessels； severe stromal edema，inflammatory cell infiltration and iron-choledrin depositionwere observed. Compared with model group， the fetal survival rates， serum levels of β-HCG and P， the expressions of PCNA and HB-EGF mRNA and proteins in the placenta and decidua tissue of soybean isoflavone groups increased significantly （P＜ 0.05）， while pathological changes were improved significantly； cell apoptosis index in the placenta and decidua tissue， the expressions of Fas， FasL mRNA and proteins in the placenta and Fas mRNA and protein in the decidua tissue decreased significantly （P＜0.05）. The effect of soybean isoflavones was dose-dependent （P＜0.05）. CONCLUSIONS Soybean isoflavone has protective effect on threatened miscarriage， the mechanism of which is related to down-regulating the expressions of Fas and FasL mRNA and protein at the maternal-fetal interface， and up-regulating the expressions of mRNA and protein of PCNA and HB- EGF.
ABSTRACT
Objective To understand the epidemiological characteristics and psychological factors of senile arrhythmia in Xining area, and provide theoretical basis for the prevention and treatment of senile arrhythmia. Methods A total of 518 elderly patients treated in the department of Cardiology in Xining area from June 2018 to June 2020 were selected and divided into control group (without arrhythmia) and study group (with arrhythmia) according to whether the patients were complicated with arrhythmia. All subjects underwent 24h electrocardiographic monitoring to record heart rate, heart rate lead electrocardiogram and 24h dynamic electrocardiogram examination. Refer to the patient's medical records for general information, including age, gender, coronary heart disease, hypertension, etc.; Psychological factors such as depression, anxiety, sleep and quality of life were analyzed. The correlation between PSQI score, HAMA-14 score, HAMD-17 score and arrhythmia was analyzed by Pearson correlation analysis. Results Among 518 patients, 305 (58.89%) were complicated with arrhythmia, including 155 males and 150 females, with an average age of 76.15±3.79. Atrial arrhythmia accounted for 38.36% (117/305), sinus tachycardia accounted for 28.52% (87/305). Ventricular arrhythmias accounted for 11.48% (35/305); The incidence of arrhythmia in 70-79 year olds was significantly higher than that in 60-69 year olds (χ2=8.358 , P2=6.801, P2=1.534, P>0.05). The incidence of arrhythmia was significantly higher in patients with hypertension and coronary heart disease (χ2=16.401, χ2=9.772 , P<0.05). There were significant differences in PSQI score, HAMA-14 score, HAMD-17 score between the two groups (P<0.05). Pearson correlation analysis showed that PSQI score, HAMD-14 score and HAMD-17 score were positively correlated with the occurrence of arrhythmia in the elderly population in Xining area, with correlation coefficients r=0.417 , 0.607 , 0.653 (P<0.05). Conclusion The incidence of arrhythmia increases in the elderly population in Xining area, mainly in the rural elderly population, which is associated with depression and anxiety and sleep disorders and other psychological factors. Early detection and early intervention can improve the response to treatment and accessibility.
ABSTRACT
Objective To explore the influencing factors of renal injury in elderly patients with cor pulmonale, and to provide information for the prevention of renal injury in patients with cor pulmonale. Methods A total of 309 elderly patients with cor pulmonale over 60 years old treated in our hospital from June 2019 to December 2020 were included in the study. According to the patients with renal injury , they were divided into cor pulmonale renal injury group (case group) and cor pulmonale non renal injury group (control group). The basic information of the two groups and the influencing factors of potential renal injury in the past were collected, The influencing factors of renal injury in elderly patients with cor pulmonale were analyzed by univariate analysis and regression model. Results The single factor analysis of the case group was higher than that of the control group, with a male age of 80 years, smoking history, family history of diabetes, concurrent infection, diabetes mellitus and left ventricular ejection fraction (LVEF) 80 years old (or = 3.142), smoking history (or=2.115) , concurrent infection (or=4.263) , and excessive systolic blood pressure (or=2.279) were the risk factors potentially increasing the risk of renal injury, which were statistically significant (P < 0.05). Conclusion Elderly patients with cor pulmonale over 80 years old , with smoking history and abnormal blood pressure , as well as those complicated with infection , have an increased risk of renal injury. It is worthy of clinical attention and relevant preventive measures to improve the prognosis of patients.
ABSTRACT
Objective To assess the quality of reports of clinical randomized controlled trials (RCTs) published in Chinese Journal of Dermatology from 2007 to 2016,and to provide a reference for standardization of clinical paper writing.Methods Based on the consolidated standards of reporting trials (CONSORT) 2010 statement,an evaluation form was designed and used to assess the quality of the clinical RCT articles published in Chinese Journal of Dermatology from 2007 to 2016.Results A total of 94 RCT articles were enrolled,including 45 articles from 2007 to 2011,and 49 articles from 2012 to 2016.Among these articles,the writing of introduction and discussion parts was relatively standardized.In the method and result parts,the proportions of articles correctly reporting blinding (23 articles,24.47％),sample size (0 article),primary and secondary outcome measures (21 articles,22.34％),participant flow (0 article),loss to follow-up (32 articles,34.04％) and compliance (13 articles,13.83％) were low,while the proportions of those correctly reporting inclusion and exclusion criteria,intervention measures,statistical methods,starting and ending time of follow-up and baseline data were all over 80％.Conclusion Most contents of the RCT articles published in Chinese Journal of Dermatology are standardized and clear,but the reporting of blinding,compliance,sample size,participant flow and so on,is insufficient,and close attention should be paid to these items.

<p><b>OBJECTIVE</b>To observe the effects of auricular acupuncture on the learning and memory abilities of model rats with Alzheimer's disease (AD), and investigate its mechanism.</p><p><b>METHODS</b>Thirty SD rats were randomly divided into a control group, a model group and an auricular acupuncture group, 10 rats in each group. The model rats with AD were established by multiple injections with Okadaic Acid into the CA1 region of hippocampus. In the control group, the same quantity injection with Dimethyl Sulfoxide (DMSO) was applied on experimental rats. The auricular acupoints of "Nao" (brain) and "Shen" (kidney) were used for treating in the auricular acupuncture group, in contrast, the auricular region were not treated in the model and the control groups. The learning and memory capabilities of the rats were assessed with Morris Water Maze behavioral test, and the expressions of choline acetyltransferase (ChAT) and glial fibrillary acidic protein (GFAP) were examined by immunohistochemistry.</p><p><b>RESULTS</b>Comparing with the model group, the treated AD rats with auricular acupuncture was showed that the average escape latency was obviously shortened in the place navigation test (P<0.01), the movement time in plateform quadrant was obviously prolonged in the spatial probe test (P<0.05), and the number of traversing platform obviously increased (P<0.01) after the platform was taken away. The expression of ChAT increased in the hippocampus and cortex (P<0.01, P<0.05), but the expression of GFAP obviously decreased in the CA1 region of hippocampus (P<0.01).</p><p><b>CONCLUSION</b>Auricular acupuncture can improve the learning and memory capability of the model rats with AD. Its mechanism might be related with decreasing cholinergic neuron damage and reducing the abnormal activation and hyperplasia of astrocyte.</p>

Objective To investigate the neuroprotective effect of [Gly14]-humanin (HNG) in rats with intracerebral hemorrhage (ICH). Methods Thirty healthy male SD rats were randomly divided into 3 groups, namely the sham operated group (10 rats) with needle insertion only, ICH model group (10 rats) with injection of autologous whole blood into the right caudate nucleus, and HNG treatment group (10 rats) with HNG injection into the lateral cerebral ventricle after simulated ICH as in the model group. The changes in the glial cells and cell apoptosis around the hematoma were detected 72 h after the operation. Results The astrocytes and microglial cells in rats receiving HNG injection into the cerebral ventricles showed smaller cell size and shorter and thinner cell processes than those in ICH model group. The numbers of cells positive for glial fibrillary acidic protein (GFAP) and OX42 and the apoptotic cells (as found by TUNEL assay) around the hematoma were significantly reduced in comparison with those in the ICH model group (P<0.05), but still remained significantly higher than those in the sham-operated group (P<0.05). Conclusion HNG can ameliorate the inflammatory response occurring in and around the hematoma and provide some neuroprotection in rats with ICH.
