ABSTRACT
Objective To understand the current status of health literacy among caregivers of patients with liver cancer and its influencing factors so as to provide a basis for improving the level of health literacy among caregivers of patients with liver cancer.Methods Using convenience sampling method,the caregivers of the liver cancer patients,who were admitted to the Department of Interventional Radiology of a certain grade ⅢA hospital in Changsha City,Hunan Province of China between April and October of 2022 and who met the inclusion and exclusion criteria,were selected as the research objects.The general information questionnaire,Health Literacy of Caregivers Scale-Cancer(HLCS-C),and Simplified Coping Style Questionnaire(SCSQ)were used to conduct the survey.Multiple linear regression analysis was used to analyze the factors influencing the health literacy among caregivers of patients with liver cancer.Results A total of 204 valid questionnaires were collected.The score of health literacy of caregivers was(123.08±16.66)points.The results of multiple linear regression analysis showed that the residence location,the monthly income per capita of the family,the number of hospitalization times,the length of care,work/study status,and coping style were the main factors influencing the health literacy(P<0.001),which explained 81.9%of the total variance.Conclusion The health literacy among the caregivers of patients with liver cancer is at a moderate level.Clinical medical staff can implement individualized health education by evaluating caregivers with different characteristics,encourage caregivers to seek and grasp disease-related information,and help the caregivers to adopt positive coping styles,so as to improve their health literacy.
ABSTRACT
Objective:To summarize the clinical and laboratory characteristics of infectious mononucleosis (IM) in children.Methods:Clinical features and laboratory results of 270 cases with IM admitted to the Department of Pediatrics in Strategic Support Force Medical Center of People′s Liberation Army from January 2012 to December 2020 were retrospectively analyzed. χ2 test was used for comparison between groups. Results:IM mainly occurred in children aged 5 months to 18 years old in autumn and spring.The highest incidence rate (105 cases, 38.9%) was 3-<6 years old (preschoolers). There were 253 cases (93.7%) with fever, 266 cases (98.5%) with adenopharyngitis, 196 cases (72.6%) with tonsil pseudomembrane or exudation, 248 cases (91.9%) with cervical lymphadenopathy, 92 cases (34.1%) with eyelid edema, 202 cases (74.8%) with nasal obstruction, 124 cases (45.9%) with nasal obstruction and snoring, 24 cases (8.9%) with rash, and 112 cases (41.5%) with splenomegaly.A total of 225 cases (83.3%) presented with typical triplets of IM (fever, adenopharyngitis and cervical lymphadenopathy). Sixty-two IM patients were complicated with pulmonary infections and 3 cases with diarrhea.The main co-infection pathogens in children with IM were Mycoplasma pneumonia (MP) (79 cases, 29.3%), influenza A or B virus (34 cases, 12.6%), Streptococcus pneumonia (SP) (18 cases, 6.7%), adenovirus (22 cases, 8.1%) and cytomegalovirus (3 cases, 1.11%). A total of 46 cases (17.0%) had multiple infections.Laboratory test results suggested that absolute lymphocyte count ≥5.0×10 9/L was found in 199 cases (73.7%), and abnormal lymphocyte ratio >0.10 was found in 225 cases (83.3%). Some children had elevated transaminase levels.Epstein-Barr virus capsid antigen-immunoglobulin M (EBV-VCA-IgM) was positive in 249 cases (92.2%), Epstein-Barr virus capsid antigen-immunoglobulin G (EBV-VCA-IgG) was positive in 238 cases (88.1%), and Epstein-Barr virus nuclear antigen-immunoglobulin G (EBV-NA-IgG) was negative in all cases.EBV-VCA-IgG showed low affinity in all cases (<40%). EBV DNA tests of peripheral blood plasma were carried in 153 cases, of which 118 cases (77.1%) were positive. Conclusions:EBV related IM mainly attacks preschoolers.Most patients are presented with typical triplets of IM.Eyelid edema, nasal obstruction, snoring, splenomegaly and elevated transaminase levels are prevalent in IM children.Most cases have a favorable prognosis.
ABSTRACT
Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.
ABSTRACT
Coronary heart disease is the leading cause of death in the United States and many developed countries. Percutaneous coronary intervention (PCI) is an important means to treat coronary heart disease. However, PCI can not eliminate the risk factors of coronary heart disease. As an important auxiliary means of PCI, cardiac rehabilitation can significantly slow down the progress of atherosclerosis, reduce cardiovascular events, improve patients′ exercise tolerance and the quality of life of patients. It have been developing vigorously in developed countries and achieved remarkable results. This paper will review the effects of cardiac exercise rehabilitation and the research on cardiac exercise rehabilitation in different clinical stages.
ABSTRACT
Hospitals today are confronted with new challenges in environmental hygiene management. Based on recent literatures and norms at home and abroad, this review analyzed such challenges and defects found in the environmental hygiene management of hospitals in China. The problems include but are not limited to the following: incomplete environmental management system and norms, insufficient staffing and funding support, lack of HR management mechanism in terms of employment, training, appraisal and reward/penalty, as well as poor hygiene awareness of hospital environmental services staff. In view of these problems in the hospitals, the authors provide specific countermeasures as follows: establishing new environmental hygiene management models, improving management mechanisms, creating positive and normalized cultural atmosphere for environmental infection control, and applying informatization to upgrade environmental hygiene quality. These measures are expected to serve as references for improving surrounding hygiene of patients.
ABSTRACT
Objective@#To evaluate the long-term efficacy of a second generation biodegradable polymer sirolimus-eluting stent (EXCEL2) in treating patients with de novo coronary artery diseases.@*Methods@#CREDIT Ⅱ trial was a prospective, multicenter, randomized, controlled study, conducted at 15 Chinese cardiac centres from November 2013 to December 2014. In this analysis, eligible patients for coronary stenting (n=419) were randomized to receive either the EXCEL2 stent (n=208) or the EXCEL stent (n=211). The primary endpoint was target lesion failure (TLF) at 3 years after PCI defined as a composite endpoints of cardiac death, target vessel myocardial infarction (TVMI), or clinically indicated target lesion revascularization (CI-TLR). Secondary endpoints included patient-oriented composite endpoint (PoCE) including all-cause death, all MI, or any revascularization at 3 years and independent components, and stent thrombosis according to Academic Research Consortium′s (ARC) definition.@*Results@#Among 419 enrolled patients, 413 (98.6%) patients completed 3-year clinical follow-up. Compared with the EXCEL group, 3-year TLF (5.4%(11/204) vs. 11.5% (24/209), P=0.025) and PoCE (9.8% (20/204) vs. 20.1% (42/209), P=0.003) were significantly lower in the EXCEL2 group. The cumulative event rate of CI-TLR (2.0% (4/204) vs. 5.7% (12/209), P=0.042) and any revascularization (4.9% (10/204) vs. 14.4% (30/209), P=0.001) were statistically lower in the EXCEL2 group than in the EXCEL group. There were no significant difference between two groups in terms of all-cause death and all MI. Rates of stent thrombosis were low without significant difference between the two groups (EXCEL2 vs. EXCEL, 1.0% (2/204) vs. 2.9% (6/209), P=0.285).@*Conclusion@#3-year clinical follow-up results demonstrate that EXCEL2 stents are effective and safe in treating CAD patients with de novo coronary lesions.

ABSTRACT
To explore the protective effect of rosiglitazone (RGZ) on hepatic ischemia reperfusion injury (HIRI) and the underlying mechanisms. Methods: A rat model of ischemia-reperfusion injury was established by clamping the left and middle lobe of liver with noninvasive vascular clamp. A total of 30 Sprague-Dawley rats were randomly divided into a sham group, an HIRI group, and a RGZ group (10 rats in each group). Two hours after reperfusion, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, lactate dehydrogenase (LDH) level, malondialdehyde (MDA) content and catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities were examined. HE staining was used to observe liver pathological morphology. The liver peroxisome proliferators-activated receptor γ (PPAR-γ), p-PPAR-γ, nuclear factor related factor 2 (Nrf-2), antioxidant response element (ARE), heme oxygenase 1 (HO-1) and quinone oxidoreductase-1 (NQO-1) were detected by Western blot. Results: Compared with the HIRI group, the levels of ALT, AST, LDH and MDA in the RGZ group were significantly decreased (all P0.05). Conclusion: PPAR-γ agonist RGZ can attenuate HIRI, which may be related to activating Nrf2/ARE signaling pathway and enhancement of antioxidant ability.

ABSTRACT
Objective To compare safety and feasibility using radial versus femoral access during cardiac catheterization of patients who had previously undergone coronary artery bypass graft ( CABG) surgery. Methods We retrospectively evaluated 116 consecutive patients who underwent graft intervention via the transradial (TRA group, n = 46) or transfemoral approach (TFA group, n = 70), and observed the baseline clinical characteristics, angiography characteristics and complications between the 2 groups. Results The baseline clinical characteristics between the 2 groups were similar ( all P > 0. 05) . No significant difference was observed in angiography characteristics and procedural parameters including operation time, radiation exposure and puncture time between the 2 groups (all P > 0. 05). There was no significant difference in major adverse cardiac events during hospitalization. PCI to graft vessels were all successful and procedural success rates were similar between the 2 groups (P = 0. 669). Vascular access site complications were significantly lower ( P = 0. 03) in the TRA group. No access site complication was recorded in the TRA group. 7 cases (10. 0% ) with complications were recorded in the TFA group including 1 case of major bleeding (1. 4% ), 3 cases of minor bleeding (4. 3% ), 2 cases of local hematorna (2. 9% ) and 1 case of A-V fistula formation. Conclusions In contrast to the transfemoral route, the rate of major vascular complications was negligible using the transradial approach.
ABSTRACT
Objective To analyze the clinical, imaging and interventional data of patients with chronic total occlusion (CTO) lesions without myocardial infarction (MI) and to summarize the clinical and imaging characteristics of these patients. Methods The data of 2651 patients with CTO verified by coronary angiography between January 1995 and December 2014 were analyzed retrospectively. Results There were 1466 CTO patients (55. 3%) without MI (the control group) and 1185 CTO patients (44. 7%) with MI ( the MI group). The age, percentage of female patients, unstable angina, hypertention, mean triglyceride levels, left ventricular ejection fraction ( LVEF) were lower in the MI group than in the control group ( all P﹤0. 05). The rates of heart failure and serum creatinine levels were higher in the MI group than the control group (both P﹤0. 05). The rate of multi-vessel disease was higher in the control group than in the MI group (81. 4% vs. 76. 5%, P﹤0. 05). According to the target CTO vessel location, patients in the control group had lower rates of CTO in LAD (36. 2% vs. 40. 7%, P=0. 007) and higher rates of CTO in LCX (17. 0%vs. 12. 7%, P﹤0. 001). Patients in the control group without MI had better collateral circulation than that in the control group (32. 7% vs. 27. 0%, P﹤0. 001). There were no differences in success rate of PCI and complete revascularization between the two groups. Conclusions The present study showed that the CTO patients without MI were associated with better collateral development compared with the CTO patients with MI. Age, gender, unstable angina encouraging ischemic preconditioning and hypertension may be beneficial by facilitating collateral development through endogenous cardioprotective mechanisms.

ABSTRACT
Objectives The cellular repressor of E1A-activated genes (CREG), a novel gene, was recently found to play a role in inhibiting cell growth and promoting cell differentiation. The purpose of this study was to obtain antibody against CREG protein and to study the expression of CREG protein in human internal thoracic artery cells (HITASY) which express different patterns of differentiation markers after serum withdrawal. Methods The open reading frame of CREG gene sequence was amplified by PCR and cloned into the pGEX-4T-1 vector. Glutathione-S-transferase (GST)-CREG fusion protein was expressed in E. Coli BL21 and purified from inclusion bodies by Sephacryl S-200 chromatography. Rabbits were immunized with the purified GST-CREG protein. Western blot examined with immunohistochemistry staining and the protein expression level was analyzed by Western blot in HITASY cells after serum removal. Results It was confirmed by using endonuclease digesting and DNA sequencing that the PCR product of CREG was correctly inserted into the vector. The GST-CREG protein was purified with gel filtration chromatography. Polyclonal antibody against GST-CREG was obtained from rabbits. CREG protein immunohistochemistry staining displayed a perinuclear distribution in the cytoplasm of HITASY cells. Results from Western blot suggested that comparing with the untreated cells upregulation of CREG polyclonal antibody against CREG was comfirmed. Using this antibody, the changes of CREG protein expression was observed in the process of phenotypic modulation of HITASY cells. These results provide basic understanding on the relationship of CREG gene with the cell phenotypic conversion.
