Chinese Journal of Practical Nursing 2012;28(4):40-41
Objective To explore the influencing factors of pharmacotherapy effect of ectopic pregnancy and nursing measures. Methods 569 patients with ectopic pregnancy using pharmacotherapy were retrospectively analyzed in our department. Results Among 569 patients,423 patients gained successful treatment,while 146 patients failed the treatment.Blood β-HCG level,diameter of ectopic mass showed by B ultrasound were influencing factors of pharmacotherapy effect.The higher β-HCG level,the longer diameter of ectopic mass showed by B ultrasound,the lower success rate of pharmacotherapy.The patients with β-HCG<1000 mIu/ml,diameter of ectopic mass showed by B ultrasound less than 1 cm at admission acquired higher success rate of pharmacotherapy. Conclusions Patients with ectopic pregnancy who select conservative medication should be given pertinent psychological nursing,rigorous monitoring of disease condition and adverse reaction of drugs and timely and effective nursing measures,so that patients can get better nursing effect.
2.Role of RIP140 and PGC-1αin angiotensin Ⅱ mediated energy metabolism in cardiomyocytes
Chinese Pharmacological Bulletin 2015;(2):194-197,198
Aim To investigate the role of transcrip-tional cofactors receptor interacting protein 140 ( RIP140 ) and peroxisome proliferator-activated recep-tor γ coactivator-1α ( PGC-1α) in the angiotensin Ⅱ( AngⅡ) mediated energy metabolism regulation in cardiomyocytes. Methods RIP140 or PGC-1α was overexpressed via adenovirus vector system. ATP con-tents were detected by luminescence detection assay system. Real-time PCR and Western blot analysis were used to measure the expressions of RIP140 and PGC-1α genes. Results After treated with 100 nmol·L-1 AngⅡfor 36h in neonatal cardiomyocytes, the content of mitochondrial ATP was reduced notably ( P <0. 01). Accordingly, the mRNA and protein levels for RIP140 were increased. However, the mRNA and pro-tein levels of PGC-1α were downregulated markedly. What’ s more,the reduction of ATP induced by AngⅡwas further aggravated by RIP 1 4 0 overexpression , but ameliorated by overexpressing PGC-1α. Conclusion The reduction of ATP mediated by AngⅡis associated with the upregulation of RIP140 , as well as the down-regulation of PGC-1α.

To study the cause of postoperative complications of coronary artery bypass grafting(CABG) and their preventive measures. 210 cases were reviewed and analyzed from 1993 to 2000, including 194 males and 16 females with a mean age of 58 7 years (range 32~78 years). 150 patients had three coronary vessels disease 101 patients had the history of myocardial infarction 33 patients were in heart function Ⅲ~Ⅳ(NYHA) CABG under cardiopulmonary bypass(CPB) were performed in 200 cases, and off-pump CABG in 10 cases The average number of grafts were 3 1. Cardiac valve replacement and plastic operation were done in 25 patients at the same time, and left ventricular aneurysms were resected in 8 cases The hospital mortality was 1 9%(4/210), and 13 patients had perioperative myocardial infarction. The recurrence rate of angina was 5 2%(11/210). The incidence of postoperative arrhythmia was 16 2%(34/210). A rise of creatine kinase level was observed in 145 cases after CABG. Incidence of painless myocardial infarction was very high(11/13) in perioperative myocardial infarction, therefore the level of myocardial enzymes should be assessed after the operation and the changes in electrocardiogram should be monitored in order to avoid misdiagnosis. The great majority of postoperative arrhythmias were atrial flutter,atrial fibrillation, and supraventricular tachycardia. Normal sinus rhythm was readily restored by conventional treatment.

Tyrosinase is a key enzyme related to skin pigmentation disorders of elderly people, while self-aggregation of the amyloid-beta peptide, Abeta42, has been considered as a key event in the pathogenesis of Alzheimer's disease (AD). The present study was undertaken to investigate the inhibitory effects of 20 samples from Rhodiola species on tyrosinase and Abeta42 aggregation, and to isolate their corresponding bioactive components. The results demonstrated that the oligomeric proanthocyanidins (OPCs) commonly found in Rhodiola species were the major bioactive components corresponding to their anti-tyrosinase and anti-Abeta42 aggregation bioactivities. Salidroside, a representative compound of Rhodiola plants, proved not to be active in the present studies.

Nuclear receptors(NRs)superfamily signaling plays an important role in regulating the expression of gene involved inenergy homeostasis.The nuclear receptors regulate target gene expression through the recruitment of coregulatory proteins,which act as scaffolds or plateforms for linking NRs with enzyme complexes that modify DNA and histones.As a transcriptional co-repressor for NRs,RIP140 negatively regulates the transcription of target gene in metabolic tissue,such as adipose tissue,muscle and liver.In the absence of RIP140,genes expressions involved in metabolic pathways were upregulated including glycolysis,triglyceride synthesis,TCA cycle,fatty acid ? oxidation,mitochondrial electron transport and oxidative phosphorylation.RIP140 may be a candidate therapeutic target for metabolism syndromes.

Objective:To explore the utility of psychiatric service of clients having online counseling for anxiety or depression. Methods:The anxiety group was consisted of clients (n=107) who were positive in the Self-rating Anxiety Scale (SAS) online, similarly the depression group was consisted of clients (n=102) with positive results in Self-rating Depression Scale (SDS) online screening. Both groups were investigated with the questionnaires include issues related to the clinical features, diagnostic categories and treatment vs professional advice on clients. Results:In the anxiety group (male 69/female 38), the average age was 28+8, 88(82.2%) with more than 15 years education. In the depression group (male 57 vs. female 45), the average age was 29+8, 81(79.4%) with more than 15 years education. None was illiterate. For the age, sex, education and occupation, there was no significant difference between the two groups. 81(79.4%) clients in the anxiety group and 89(87.2%) clients in the depression group were advised to visit psychiatrists or psychologists. A few were advised to counseling online only and there was no significant difference between the two groups. The main diagnoses were mood disorders, neurosis and psychogenic disorders. Actually, 29(27.1%) in the anxiety group were treated with anxiolitics, 31(30.2%) in the depression group were treated with antidepressants at local clinics. Conclusion:Most of the clients should visit psychiatrists or psychologists, and a few may have their psychological counseling online only. Health education and psychological counseling online may be helpful to improve the rate of diagnosis and treatment of mental disorders in local clinics.
