Objective:Evaluate the effects of brief mindfulness meditation training on improving negative e-motions,mindfulness attention awareness,and sleep quality in patients after percutaneous coronary intervention(PCI)for coronary heart disease.Methods:Eighty-four patients with coronary heart disease after PCI admitted to the cardiology department were selected.According to the principle of simple randomization,they were divided into an intervention group of 42 cases and a control group of 42 cases.The Self Rating Anxiety Scale/Self Rating De-pression Scale,Mindfulness Attention Awareness Scale,and Pittsburgh Sleep Quality Index Scale were used as eval-uation indicators before and after intervention.Results:The difference in total scores of anxiety,depression,and mindfulness attention awareness before and after intervention in the intervention group was higher than that in the control group(P＜0.05).The difference in total sleep score,sleep quality,time to fall asleep,sleep duration,use of hypnotic drugs,daytime dysfunction,and total sleep score before and after intervention was higher than that of the control group(P＜0.05).Conclusion:It suggests that brief mindfulness meditation training could alleviate negative emotions in patients with coronary heart disease after PCI,improve mindfulness awareness,and improve sleep quali-ty.

Objective:To observe any effect of electroacupuncture (EA) on the expression of phosphorylated extracellular signal-regulated protein kinase (p-ERK1/2) and phosphorylated cyclic adenosine monophosphate response element binding protein (p-CREB) in the spinal dorsal horns of diabetics experiencing neuropathic pain.Methods:Eight rats were randomly selected from 30 healthy male Sprague-Dawley rats as the normal group (N), and the remaining twenty-two rats were treated with a single high-dose intraperitoneal injection of streptozotocin (STZ) to establish a neuropathic pain model. The rats modeled successfully were randomly divided into a model group (M, n=8) and an EA group ( n=8). In the EA group, electroacupuncture was applied at the bilateral Hou san li and Kunlun acupoints starting on the 15th day after the STZ injection. The daily sessions lasted 30 minutes for 1 week. Body weight (BW), fasting blood glucose (FBG) and paw withdrawal latency (PWL) were observed before the STZ injection and on the 7th, 14th, and 21st days afterward. The expression of p-ERK1/2 and p-CREB in the dorsal horns of the rats′ spinal cords was detected using western blotting. The count of p-CREB-positive cells in the dorsal horns and their co-localization with neurons was detected using immunofluorescence. Results:In comparison with the N group, the average BW of the M group on the 7th, 14th and 21st days after the STZ injection was significantly lower, while the average FBG was significantly higher. There was no significant difference between the M and N groups in the average PWL on the 7th day after the STZ injection, but it had decreased significantly in the M group on the 14th and 21st days. Compared with the M group, the average PWL of the EA group was significantly longer on the 21st day after the injection. The expression of p-ERK1/2 and p-CREB protein in the spines of the M group was significantly higher than in the N group. p-CREB positive cells were more numerous in the M group compared with the N group, while in the EA group they were fewer. P-CREB was co-located with neurons in the spinal dorsal horn.Conclusion:EA can alleviate neuropathic pain effectively, perhaps by inhibiting the expression of p-ERK1/2 and p-CREB in the dorsal horns of the spinal cord.

Objective:To analyze the changes in self-efficacy and its influencing factors in type 2 diabetic patients after community-based self-management group intervention.Methods:From August to November 2014, a 3-month community-based self-management intervention study of type 2 diabetes patients was implemented in Fangshan District, Beijing. 510 patients were recruited through posters, household inquiries and telephone notification and then were randomly divided into intervention group (260 patients) and control group (250 patients). Finally, 500 patients completed the study, including 259 in the intervention group and 241 in the control group. Self-efficacy score was measured through face-to-face interview at different time points, including pre-intervention, post-intervention, 2 years after the intervention and 5 years after the intervention, respectively. A two-level random coefficient model was fitted to analyze the long-term trend of self-efficacy and its relationship with group intervention.Results:Individual-level educational attainment, disease duration as well as their treatment plans had a positive correlation with self-efficacy of type 2 diabetic patients while gender and age did not affect their self-efficacy. Patients with junior middle school education, senior high school education and university and above education had 4.66 ( P<0.05), 6.40 ( P<0.05) and 11.02 ( P<0.05) points higher than those with primary education, respectively. The self-efficacy of diabetic patients increased by 0.23 ( P<0.05) for each additional course year. The effect of treatment plan on self-efficacy was mainly reflected in the self-efficacy of taking medication or insulin injection as prescribed and blood glucose monitoring. After controlling for the confounding factors, i.e., gender, age, disease duration, educational attainment, and treatment plan, self-efficacy scores at the post-intervention increased in both groups compared to those at the pre-intervention. The intervention group had 7.95 points higher than the control group ( P<0.05). After the intervention, the self-efficacy scores of both groups decreased year by year while the intervention group declined faster, with 5.41 points ( P<0.05) at 2 years after the intervention and 8.94 points ( P<0.05) at 5 years after the intervention. Conclusion:Community-based self-management group intervention could improve the self-efficacy of type 2 diabetic patients while the self-efficacy decreases year by year in the absence of follow-up intervention.

Objective:To investigate the feasibility and safety of submaximal balloon dilation and to perform small-diameter stent for symptomatic carotid artery severely stenosis before coronary artery bypass grafting(CABG).Methods:From January 2016 to December 2019, 30 patients of the Department of Neurointervention in Beijing Anzhen Hospital with symptomatic carotid artery stenosis(≥70%) and the left main trunk or triple-vessel of coronary artery disease were analyzed retrospectively. General information, clinical characteristics, and imaging data of all cases were collected. All patients underwent submaximal balloon dilation and small-diameter stent implantation. Preoperative comorbidities or risk factors included hypertension 23 cases(76.7%), diabetes 10 cases(33.3%), hyperglycemia 14 cases(46.7%), moking 13 cases(43.3%). Left main trunk disease 6 cases(20.0%), three-vessels disease 24 cases(80.0%), mitral regurgitation 1 case(3.3%), stable angina 25 cases(83.3%), myocardial infarction 8 cases(26.7%), cerebral infarction 24 cases(80.0%) and transient ischemia attack(TIA) 6 cases(20.0%) caused by ipsilateral carotid artery stenosis. The median National Institutes of Health Stroke Scale(NIHSS) score was 2(0-3), and the median modified Rankin Scale(mRS) score was 1(0-1) before the operation. The mean interval between carotid artery intervention and CABG was(23.4±8.2)days.Results:29 cases(96.7%, 29/30) underwent CAS-CABG operation successfully. In one case of carotid artery extreme tortuosity, the emboli protective device could not place the distal carotid artery. In the operative procedure, 27 cases(90.0%, 27/30) underwent with 3mm diameter balloon, only 3 cases(10.0%) with 3 mm balloon after pre-dilatation with 2 mm diameter balloon because of severely high-grade stenosis(99%). 25 cases(83.3%) with 7mm diameter stents and 5 cases(16.7%) with 6 mm diameter stents, including 22 cases(73.3%) with a closed-cell stent and 8 cases(26.7%) with an open-cell stent. In the perioperative period, the heart rate of two patients was lower than 50 BPM during operation and returned to normal after using atropine immediately. Another patient presented with chest tightness during interventional therapy. TNI elevation was examined urgently. After oxygen inhalation and intravenous infusion of Nitroglycerin, the patient's symptoms improved rapidly. No cardiac and cerebrovascular complications occurred during the perioperative period of CABG, no cardiac-related complications occurred within 30 days of follow-up, one case of TIA and 1 case of cerebral infarction. After intensive anti-platelet aggregation and lipid-lowering treatment, two patient's symptoms improved. There were no death cases in all patients during carotid artery interventional therapy, perioperative CABG and 30-day follow-up. Thirty days later, we performed a clinical follow-up of 23 cases, median 4.5(3.0-7.9) months, mRS Score Median 1(0-1). One patient presented with TIA, any patient had no symptoms of the cardiac or nervous system. Image follow-up of 17 cases, median 3.5(2.8-4.5) months, carotid artery ultrasound showed in-stent restenosis(stenosis rate>50%) in 1 case, the patient was asymptomatic restenosis, continue treatment of aggressive anti-platelet and lipid-lowering drugs.Conclusion:Submaximal balloon dilation and performing small-diameter stent for symptomatic carotid artery severely stenosis before CABG is safe and feasible, which could not only reduce the incidence of vagus reflex resulted in acute coronary syndrome during carotid artery stenosis intervention but also morbidity of acute ischemic stroke events during CABG.

Objective:To investigate the associations of brain white matter integrity deficits, and to explore the association of fractional anisotropy (FA) abnormality with clinical symptoms and cognitive impairments, as well as the prediction effect of the FA alterations on symptoms and cognitive function outcomes in the acute stage of schizophrenia from the whole brain level based on magnetic resonance diffusion tensor imaging (DTI).Methods:From November 2019 to December 2020, thirty-eight patients with first-episode schizophrenia and 38 healthy controls were recruited in this study. Wisconsin card classification test (WCST), digit span test (DST forward/backward), verbal fluency test, Stroop (A/B/C), trail making test (TMT-A/B), as well as positive and negative syndrome scale (PANSS) were utilized to evaluate patients' cognitive function and clinical symptoms both before and after 8 weeks of risperidone monotherapy. T1-weighted images and DTI data of all the subjects were collected . FSL and SPM8 were used to preprocess MRI data and compare the between-group differences of FA. Support vector machine (SVM) analysis was used to evaluate the accuracy of abnormal FA values in differentiating schizophrenic patients from healthy controls. Finally, stepwise multiple regression analysis or generalized linear models were used to explore the associations between white matter integrity and symptoms or cognition.Results:Before treatment, patients' FA values of right medial temporal lobe (mTL), cuneus, anterior cingulate gyrus (ACG) and inferior parietal lobe (IPL) were significantly lower than those in healthy controls ( P<0.01, GRF corrected), and patients' FA values of bilateral middle cingulate gyrus (mCG) were significantly higher than those in the control group ( P<0.01, GRF corrected). SVM analysis showed that four combinations could distinguish the patients from the control with the most accurate rate of 89.47%. Patients' baseline decreased FA values in the right IPL were positively associated with their increased total response time in WCST ( β=0.489, P=0.003, FDR corrected), correct response time in WCST ( β=0.450, P=0.008, FDR corrected), error response time in WCST ( β=0.435, P=0.008, FDR corrected), TMT-B ( β=0.296, P=0.042, FDR corrected), Stroop-C ( β=0.345, P=0.035, FDR corrected), and PANSS-P ( β=0.321, P=0.042, FDR corrected). Reduced FA values in the right mTL in patient group were significantly negatively related to the total time spent on the TMT-A ( β=-0.425, P=0.009, FDR corrected) and TMT-B ( β=-0.325, P=0.026 with FDR correction). Increased FA values in right mCG in patient group demonstrated positive associations with total response time in the WCST ( β=0.585, P=0.002, FDR corrected), correct response time in WCST ( β=0.524, P=0.003, FDR corrected), error response time in WCST ( β=0.536, P=0.003, FDR corrected) and total time consuming in TMT-B ( β=0.484, P=0.004, FDR corrected), as well as negative associations with DST-forward ( β=-0.319, P=0.042, FDR corrected). After treatment, patients' percentage changes in total response time of WCST ( β=0.715, P<0.001, FDR corrected), correct response time of WCST ( β=0.752, P<0.001, FDR corrected), as well as total time-consuming of TMT-A ( β=1.333, P=0.001, FDR corrected) showed positive correlations with baseline increased FA values in the left mCG. Percentage alteration of Stroop-B was negatively correlated with baseline FA values in the right cuneus ( β=-0.745, P=0.015, FDR corrected). Conclusions:The combination of abnormal FA values in multiple brain regions may be potential biomarkers to distinguish schizophrenic patients from healthy volunteers. There was regional dependence in the associations of the impairment of white matter integrity with the cognitive impairment, the severity of psychopathological symptoms as well as the prognosis of patients in the acute stage.

Objective:To investigate the cognitive level of wearing and removing personal protective equipment in COVID-19 isolation wards of Wuhan Fangcang shelter hospital, and provide the scientific basis for the training of hospital protection. Methods:Cognitive level of wearing and removing personal protective equipment in Wuhan Fangcang shelter hospital were investigated by using a questionnaire which included 14 related scales, including putting on and off protective equipment, hand hygiene disinfection and so on.Results:The total scale score of non-medical workers was 48.82±9.65, which was lower than the total scale score of doctors (55.46±1.29) and nurses (55.0±2.36), P<0.05. The each score of 14 items in the scale of non-medical workers was all lower than those of doctors and nurses ( P<0.05). There were no significant differences in scale scores among doctors, nurses and medical technicians. The total score of the scale of non-medical workers in later period was 55.23±3.26, which was significantly higher than the total score of 44.50±10.14 in previous period, P<0.001. The total score of nurses and medical technicians in the later period was higher than those in the previous period, and the difference was statistically significant. There was no significant difference between the total score of the scale in the later period and that in the previous period. Conclusions:The cognition level of non-medical workers on wearing and removing personal protective devices was lower than those of doctors and nurses, strengthening the practice could improve cognition.

Objective: To assess the effect of health coaching on interventional effect in high-risk population of stroke. Methods: A baseline survey was conducted among 897 residents aged 40 years and above selected by cluster sampling method in a community of Shijiazhuang city from January 2016 to June 2016, and 178 subjects were identified as high risk population of stroke. The high-risk subjects were randomly divided into two groups: the control group (n=89) was given routine health education, while the intervention group (n=89) received health coaching based on motivational interview for 13 months. The behavioral risk factors and self-efficacy scores were compared between two groups before and after intervention. Results: There were no significant differences in behavioral risk factors between the two groups: for hypertension 72 vs. 74 cases (χ²=0.152, P=0.67), for hyperglycocemia 44 vs.48 cases (χ²=0.360, P=0.55), for dyslipidemia 62 vs. 60 cases (χ²=0.104, P=0.75), for smoking 35 vs.32 cases (χ²=0.215, P=0.64), for obesity 50 vs.52 cases (χ²=0.092, P=0.76), for lack of exercises 72 vs.70 cases (χ²=0.139, P=0.71), for atrial fibrillation 14 vs. 16 cases (χ²=0.160, P=0.19). And there was no significant difference in self-efficacy scores between the two groups [(5.3±1.2) vs. (5.6±2.0), t=0.997,P=0.32]. After intervention, there were significant differences between the two groups in behavioral risk factors: for hypertension 25 vs. 34 cases (χ²=19.984, P<0.05) , for hyperglycaemia 16 vs.32 cases (χ²=8.448, P<0.05) , for dyslipidemia 30 vs. 48 cases (χ²=13.216, P<0.05) , for smoking 20 vs.28 cases (χ²=7.583, P<0.05) , for obesity 18 vs.38 cases (χ²=14.158, P<0.05) , for lack of exercises 28 vs. 36 cases (χ²=10.235, P<0.01) , for atrial fibrillation 5 vs. 13 cases (χ²=6.451, P<0.05) . And the self-efficacy scores of intervention group were higher than those of control group[ (8.4±2.1) vs. (6.8±2.2), t=4.852, P<0.01]. Conclusion Health coaching based on motivational interview is beneficial to reduce risk factors and improve self-efficacy in high risk population of stroke, which is worthy of popularization.

Objective: To examine the effects of kangaroo mother care on breastfeeding by women who delivered via cesarean section and on neonatal jaundice. Methods: The study sample consisted of 120 pairs of women who delivered via cesarean section and newborns born by cesarean delivery between August 2017 and February 2018 in the Second Hospital of Shanxi Medical University. They were randomly divided into a conventional nursing group and a kangaroo mother care group by random number table method. A total of 120 pairs of newborns and mothers met the exclusion criteria. The conventional nursing group received routine nursing, while the kangaroo mother care group was given routine nursing and received the kangaroo mother care. By determining the lactation start time, and using the Breastfeeding Assessment Tool (BAT) and Breastfeeding Self-Efficacy Scale (BSES), we evaluated the condition of breastfeeding by the women who delivered via cesarean section. We measured the transcutaneous bilirubin level using the jaundice measuring instrument to evaluate neonatal jaundice. Results: The subjects in both groups were of Han nationality and delivered via cesarean section at a gestational age of >37 weeks. No statistically significant differences were found between the two groups in terms of age, occupation, number of pregnancies, and educational background (P>0.05). No statistically significant differences were found between the two groups in terms of the newborns’ sex, birth weight, Apgar score, and birth length (P>0.05). The lactation start time in the kangaroo mother care group (42.1±10.9 h) was earlier than that in the conventional nursing group (52.7±12.8 h), with a statistically significant difference (t=4.880, P<0.001). The success rate of the initial breastfeeding in the kangaroo mother care group reached 80%, which is significantly higher than that in the conventional nursing group by 43% (χ²=17.062, P<0.001). The breastfeeding self-efficacy score (117.0±13.7) in the kangaroo mother care group was significantly higher than that in the conventional nursing group (111.3±15.9, t=2.126, P=0.036). The transcutaneous bilirubin levels in the forehead, chest, and legs (173.7±39.3, 174.1±40.1, and 120.4±32.7 μmol/L, respectively) at 72 h after birth in the kangaroo mother care group were lower than those in the conventional nursing group (194.3±43.9, 193.1±39.0, and 138.0±34.6 μmol/L, respectively), with statistically significant differences (t=-2.706, -2.640, and -2.852, respectively, P<0.05). The newborns’ defecation frequencies at 24, 48, and 72 h after birth in the kangaroo mother care group (5.5±1.7, 5.2±1.9, and 5.2±2.3, respectively) were higher than those in the conventional nursing group (4.5±1.7, 4.3±1.9, and 4.3±1.6, respectively), with statistically significant differences (t=3.122, 2.631, and 2.332, P<0.05). Conclusion The kangaroo mother care method can effectively improve the success rate of first breastfeeding and early lactation initiation time, and increase breastfeeding confidence in women who undergo cesarean section, and reduce the incidence of neonatal jaundice.

Objective: To study the difference in the flora structure and gene function of dental plaque in caries-free and caries-active preschool children by 16S rRNA sequencing. Methods: After oral examination of 96 preschool children aged 3-6 years, they were divided into 3 groups according to their decayed, missing and filled surface (dmfs) index: group CF with no caries (n=31), group ECC with moderate early childhood caries (n=29) and group SECC with severe early childhood caries (n=36). Dental plaques were collected, and DNA was extracted and then underwent metagenomic sequencing by Illumina HiSeq 2 500. The bacterial community structure was analyzed by Qiime. Results : A total of 12 phyla, 31 classes, 31 orders, 50 families, 92 genera and 1 104 species were found in the dental plaque samples of the three groups, most of which belonged to 9 dominant genera, including Streptococcus, Veillonella, etc. The microbial diversity of the dental plaques in the three groups was similar (P > 0.05). Veillonella, Lactobacillus, Megasphaera, and Scardovia in the SECC group were significantly higher than those in the other two groups. There was a significant correlation between the decayed, missing and filled surface (dmfs) index and the genus. Bifidobacterium, Veillonella, Lactobacillus had a positive correlation with the dmfs index, while Eikenella had a negative correlation with the dmfs index. Indicator species analysis showed that Atopobium, Veillonella, Megasphaera, Scardovia, Lactobacillus and Bifidobacterium had high indicative values in the SECC group. Conclusion There are significant differences in plaque microbiota among preschool children with different caries sensitivities. Veillonella, Megasphaera, Scardovia, Lactobacillus, Bifidobacterium and Atopobium may be the indicator genera of severe early children caries.
