RESUMO
Objective:To analyze the status quo of type D personality, intolerance of uncertainty and family support in first-episode stroke patients, and to explore the mediating role of family support between type D personality and intolerance of uncertainty in first-episode stroke patients, in order to provide reference for formulating relevant clinical intervention measures to promote the physical and mental health of first-episode stroke patients.Methods:This study was a cross-sectional investigation. A total of 300 patients with acute first-episode stroke who met the inclusion and exclusion criteria in the Department of Neurology of the General Hospital of Ningxia Medical University and the First People′s Hospital of Yinchuan from May 2023 to September 2023 were selected as the study objects by convenience sampling method. The general data questionnaire, Type D personality Scale-14, Family Caring Index Scale and the Intolerance of Uncertainty Scale were used to investigate them. Pearson correlation analysis was used to test the correlation between variables, and SPSS plug-in PROCESS 3.5 was used to test the mediation effect.Results:Finally, 300 questionnaires were effectively collected, including 228 males and 72 females. Patients aged ≥ 60 years old were the majority, accounting for 49.3% (148/300). The detection rate of type D personality in the first stroke patients was 37.3% (112/300), and the total score of Type D personality inventory, family support and intolerance of uncertainty of type D personality in the first stroke patients were (22.16 ± 9.95), (6.40 ± 2.23), (27.82 ± 7.93) points. The correlation analysis results showed that the intolerance of uncertainty of type D personality in the first stroke patients was positively correlated with type D personality scores ( r=0.675, P<0.001). There was a negative correlation with family support score ( r=-0.644, P<0.001). The results of mediating effect analysis showed that family support played a partial mediating role in the relationship between type D personality and intolerability of uncertainty in first-stroke patients, and the mediating effect accounted for 34.94% of the total effect. Conclusions:The mediating role of family support between type D personality and intolerability of uncertainty in first-stroke patients is established. In the future, the level of family support of patients can be continuously improved to reduce their intolerability of uncertainty, so as to promote the physical and mental health of patients and improve their quality of life.
RESUMO
Objective To investigate the gene mutations of human immunodeficiency virus (HIV)‐1 drug resistance among anti‐retrovirus (ARV ) treated‐naive men who have sex with men (MSM ) in Shanghai to provide evidence‐based data for optimized treatment .Methods All 669 treatment‐nave cases of HIV‐1 infection identified among MSM in 2013 were recruited and their plasma was collected .RNA was extracted and amplified by nest reverse transcription‐polymerase chain reaction ,and DNA was sequenced and then phylogenetically analyzed .Finally ,subtypes were identified and drug resistance was analyzed in comparison with International HIV Drug Resistance Database .Results The pol gene fragments of 645 cases were obtained .Primary drug‐resistance rate was 2 .48% (16/645) ,including mutations conferring resistance to protease inhibitor (PI) (0 .31% ,2/645) ,nucleoside reverse transcriptase inhibitors (NRTI) (0 .16% ,1/645) ,non‐nucleoside reverse transcriptase inhibitors (NNRTI) (1 .70% ,11/645) and both NRTI and NNRTI (0 .31% ,2/645) ,respectively .Mutations conferring resistance to CRF01_AE were 12 cases (2 .99% ) ,while mutations conferring resistance to CRF07_BC and CRF_01B were 0 .61%(1/163) and 4 .65% (2/43 ) including 1 case of CRF52_01B and unidentified CRF_01B , respectively . Resistance to NNRTI in B subtype were 2 .70% (1/37) .Conclusion The prevalence of HIV‐1 drug resistance‐associated mutations among MSM in Shanghai ,2013 is still low ,but resistance to NNRTI is relatively high .CRF01_AE is the major subtype of drug resistance .It is necessary to strengthen the HIV drug resistance surveillance in MSM group in Shanghai .
RESUMO
Objective To investigate the effects of micronutrients selenium(Se), vitamin E(VE), vitamin C(VC) and magnesium(Mg) on levels of TXA 2, PGI 2 in plasma of rats with hyperlipidemia induced by high fat and high cholesterol diet. Methods Sixty Wistar juvenile rats were randomly divided into five groups. Each group was fed with normal diet, high fat and high cholesterol diet (HFD), HFD+Se+VE+VC, HFD+Mg, and HFD+Se+VE+VC+Mg, respectively. After eight weeks, the rats were sacrificed for the detection of levels of lipid, TXA 2 and PGI 2 in the blood. Result Micronutrient complex (Se, VE, VC, and Mg) can significantly inhibit the increase of blood triglycerol, total cholesterol, LDL C and TXA 2 induced by HFD and can significantly increase HDL C. Conclusion Micronutrient complex (Se, VE, VC, and Mg) has the lipid lowering effect and can decrease TXA 2/PGI 2 ratio, which is beneficial to the prevention of atherosclerosis.
