ABSTRACT
Objective@#To explore the effect of group cognitive behavioral therapy (GCBT) on cognitive control among college students with high obsessive compulsive traits, to provide basic information for the psychological counseling intervention for college students.@*Methods@#From March to April 2019, 687 students were conveniently selected from 2 universities in Hefei. According to the inclusion and exclusion criteria, 58 students with high obsessive traits were selected and divided into experimental group ( n =29) and control group ( n =29) by random number table method. The experimental group received cognitive behavioral group counseling for 4 weeks (1.5 h each time, twice a week), while the control group receive no intervention. The Obsessive Compulsive Inventory Revised (OCI-R), Stroop Color Word Test (SCWT), Digital Span Test (DST), and Wisconsin Card Sorting Test (WSCT) were used to assess in two groups at baseline and 4 weeks later.@*Results@#After 4 weeks, the scores of OCI-R in the GCBT group (10.28±7.22) was lower than that of in the control group (15.90±10.20) ( t=2.42, P<0.05). Before and after intervention, compared with the control group [(21.89±6.63, 20.52±7.37)s, (8.62±4.43, 8.04±4.84)s] in Stroop C and Stroop interfere effects (SIE), the GCBT group [(22.14±4.92, 16.81±3.43)s, (8.36±3.87, 4.82±1.86)s], the interaction of time group was statistically significant ( F =14.60, 10.54, P <0.05). Compared with the control group (6.21±1.35, 6.55±1.45)times, the scores of DST reverse in the GCBT group (6.31±1.44, 7.24±1.38) times were statistically significant ( F=3.96, P <0.05).@*Conclusion@#It suggests that cognitive behavioral group counseling can improve the inhibitory control and working memory of college students with high obsessive compulsive traits, but does not change the cognitive flexibility.
ABSTRACT
Objective To summarize the clinical rehabilitation nursing practice of a patient with pleural giant solitary fibroma with Dege-Port syndrome. Methods A preoperative and postoperative rehabilitation nursing of a patient with low pulmonary function pleural giant solitary fibroma and non-islet cell hypoglycemia was analyzed and summarized. Results After psychological, hypoglycemia, and pulmonary rehabilitation, the patient was tolerant to surgery and recovered well after surgery. He was discharged from hospital on the 13th day after surgery. Conclusions For patients with difficult diagnosis, long-term pleural giant solitary fibroma with hypoglycemia and low lung function, psychological nursing, hypoglycemia symptomatic treatment, pulmonary rehabilitation to improve lung function, close observation and prevention of serious complications in patients It plays a vital role in the course of the disease and rehabilitation.

ABSTRACT
<p><b>OBJECTIVE</b>To determine whether quercetin inhibits oxidized low-density lipoprotein (Ox-LDL)-induced osteogenic differentiation and calcification of vascular smooth muscle cells (VSMCs) and understand the underlying mechanism.</p><p><b>METHODS</b>The calcification of human VSMCs following Ox-LDL treatment was assessed using alizarin red staining and by detecting ALP activity. The mRNA expressions of the bone-related genes including Msx2, BMP2 and Osterix, and the contractile proteins including SMA and SM22a were analyzed using qPCR. The effects of quercetin were investigated on OxLDL-induced VSMC calcification and changes in ALP activity, expressions of Msx2, BMP2, Osterix, SMA and SM22a, ROS levels and SOD activity. The effect of Toll like receptor 4 (TLR4) silencing mediated by siRNA transfection on cell calcification, ALP activity, gene expressions and ROS levels were investigated.</p><p><b>RESULTS</b>Ox-LDL treatment promoted VSMC calcification and up-regulated TLR4 expression. Quercetin treatment significantly attenuated Ox-LDL-induced VSMC calcification, reduced ALP activity, down-regulated the expression levels of Msx2, BMP2 and Osterix, and up-regulated the expressions of vascular smooth muscle contractile proteins SMA and SM22a. In addition, Quercetin treatment markedly increased SOD activity, reduced ROS levels and TLR4 expression in VSMCs. Silencing TLR4 expression using TLR4 siRNA also significantly decreased calcification of the VSMCs.</p><p><b>CONCLUSIONS</b>Quercetin inhibits Ox-LDL-induced VSMC calcification in VSMCs possibly by targeting the ROS/TLR4 signaling pathway.</p>
ABSTRACT
Objective To review the methodological quality of evidence-based guidelines on prevention and repair of perineal injury at vaginal delivery,and analyze the characteristics of guidelines to provide references for evidence-based decision-making.Methods We systematically searched websites of professional organizations,websites of clinical practice guidelines and databases for guidelines on prevention and repair of perineal injury,and used AGREE Ⅱ to evaluate the chosen guidelines.Results We identified totally 7 relevant evidence-based guidelines in this field.The average standardized scores of guidelines in 6 domains of AGREE Ⅱ were 90.21％(scope and purpose),68.25％ (stakeholder involvement),69.94％ (rigor of development),89.41％ (clarity of presentations),70.63％ (applicability),and 68.25％(independence),respectively.The overall standardized score for 7 guidelines was 75.65％,and the total score was 5.67 (7 points).For overall quality,4 of them were grade A and 3 of them were grade B.Conclusion The overall quality of included guidelines were high,but stakeholder involvement,rigor of development and independence in some guidelines needs to be improved.There was no Chinese evidence-based gui-deline in this field,and high-quality foreign guidelines could be used as evidence in combination with local conditions.
ABSTRACT
Objective To investigate the effect of Jinghou Zengzhi Recipe(JHZZR)on Fas apoptosis pathway in ovarian granulosa cells of rats with controlled ovarian hyperstimulation(COH)and to investigate the possible mechanism of the effect of JHZZR on improving oocyte quality. Methods To establish the model of COH,30 rats were randomly divided into the blank group,the positive group and the TCM group.The expression of Fas,Fasl,Caspase8,Caspase3 in ovarian was detected by qPCR andWestern Blot assay,respectively. Results The expression of Fas,Fasl,Caspase8,Caspase3 was lowered in the blank group and the TCM group. Conclusion JHZZR can inhibit Fas signalling,suggesting that Fas pathway may be one of the mechanisms under-lying that JHZZR improves oocyte quality.
ABSTRACT
Iodine is an essential trace element,its physiological function is realized through thyroid hormone,both iodine deficiency and excess have influences on human health.After 20-year implementation of universal salt iodization in China,the iodine deficiency disorders have been controlled effectively,while the problem of iodine excess emerged.Because of different geographical environment,dietary habits and physiological status,some people did exposed to high level of iodine.In recent years,domestic and foreign scholars carried out series of researches aiming at disclose the effects of iodine excess on human health.The health problems induced by high iodine intaking are goiter,hyperthyroidism,hypothyroidism,autoimmune thyroiditis and thyroid cancer et al.Therefore,when preventing and treating iodine deficiency,iodine excess should also be avoided,so as to achieve the ideal goal of adjust measurements according to local conditions,classification guidance,and scientific iodine supplementation.
ABSTRACT
Poly (ADP-ribose) polymerase-1 (PARP-1) is a ribozyme that widely exists in the cukaryotic cells.It plays important roles in the maintenance of genomic stability and the regulation of gene transcription and other physiological processes.PARP-1 is overactivated after ischemic brain injury,and PARP-1 gene knockout mice or PARP-1 inhibitor can reduce brain injury in a variety of models of cerebral ischemia.Therefore,PARP-1 plays important roles in the pathophysiologic processes of ischemic brain injury.The investigation of the effect of PARP-1 in cerebral ischemia contributes to further understanding the pathophysiologic mechanism of stroke and finding a new therapeutic target.
ABSTRACT
The changes of immune system following stroke mainly includes the local inflammatory responses of brain tissue and the systemic immunological changes, The former may exacerbate brain damage following stroke, the latter may increase the susceptibility to infection, and thus impact on brain function recovery and prognosis. Stroke interferes with the normal balance between the nervous system and the immune system, and its mechanism remains unclear. This article reviews the stroke-indnced immunological alterations and their mechanisms,as well as the corresponding treatment strategies in clinical practice.
