Diversified Talent Cultivation Mechanism of Early Childhood Physical Education Under the Full-Practice Concept - Oriented by Preschooler Mental Health and Intelligent Teaching.

In order to improve early childhood physical education, in this study, the talent cultivation mechanism for undergraduates was explored under the “full-practice” concept, oriented by preschooler mental health. First, from the perspective of preschooler psychology, the mechanisms of ability training and talent cultivation for undergraduates majoring in early childhood education were explored under the “full-practice” concept. Considering that the physical, psychological, and intellectual development of preschoolers shall follow the rules of physical education, and current early childhood education mainly focuses on intelligence education in China, early childhood physical education was analyzed further in this study. By investigating the undergraduate majors of early childhood education in Henan University, this study first summarized the current problems in early childhood education systems in universities. Secondly, combined with the form of physical education in kindergartens, strategies for talent cultivation and curriculum setting of early childhood physical education majors in colleges and universities were proposed. Finally, from the perspective of innovation and diversification of training forms, the cultivation of early childhood educators’ physical education ability was analyzed at multiple levels and multiple objectives, and the integrated training system of early childhood education talents was constructed. The results show that, among all the courses for early childhood education major, compulsory courses account for 81.2% and optional courses account for 18.8%. In addition, a survey on undergraduates’ attitudes toward the curriculum of their major demonstrates that 81.2% of the undergraduates thought that the range and content of practical courses should be increased, indicating that undergraduates majoring in early childhood education are dissatisfied with the current curriculum system, and they have an increased demand for practical courses. Correspondingly, it is vital to build and improve on the early childhood physical education. In terms of its talent cultivation, the “full-practice” concept helps combine theory with practice to improve the effectiveness of education and teaching, pushing forward the reform of the education system. Meanwhile, data- and intelligence-oriented teaching will become the new direction of modern sports development, as well as an important link for tracking and monitoring children’s sports teaching in China. Through the continuous introduction of wearable artificial intelligence (AI) products, real-time monitoring of children’s physical conditions can be realized, which helps improve the effectiveness of early childhood physical education.

Отношение к будущей профессии у китайских студентов, обучающихся в России

Students are a special social group who strive to obtain higher education and master a highly qualified profession. The purpose of this study was to determine the attitude of Chinese students in Russia to their future profession. It aimed to compare the attitude to the future profession of 1st and 4th-year Chinese students studying in Russia and Chinese students studying in China. Additionally, we compared the attitude to the future profession of Chinese and Russian students. The study involved 720 full-time students of humanities at Henan University (China) and Herzen State Pedagogical University of Russia (Russia). The methodology included the author’s questionnaire “Spheres of life”. Most students are satisfied with their chosen profession. The responses of Chinese students studying in Russia in the 1st year differ significantly. They are satisfied with their future profession only in 32% of cases. Chinese first-year students in Russia and especially in China have a higher readiness to enter the master’s programme than in the fourth year. On the contrary, Russian students are more willing to continue their master’s studies at the senior level. These results are explained by the high value of education in traditional Chinese culture and the desire of Chinese first-year students to fulfill their parents’ will. Later, life plans are adjusted. All students are also noted to be ready to work in their specialty, except for Chinese first-year students studying in Russia. It was revealed that the attitude to the profession of Chinese students differs from the attitude to the profession of Russian students. The identified differences are due to the adaptation difficulties of first-year students beginning their studies in a foreign country, as well as social and cultural adaptation. During their studies, Chinese students successfully overcome adaptation difficulties.

Predictive value of MB isoenzyme of creatine kinase and poisoning severity score in the prognosis of patients with wasp sting

To explore the predictive value of MB isoenzyme of creatine kinase (CK-MB) and poisoning severity score (PSS) in the clinical prognosis of patients with wasp sting. A retrospective study was conducted. The clinical data of patients who were stung by wasps admitted to emergency department of the First Affiliated Hospital of Henan University of Science and Technology from July 2017 to November 2019 were collected. The 24-hour acute physiology and chronic health evaluation II (APACHE II), CK-MB and PSS scores of the patients were collected after admission, and 28-day outcome was recorded. Spearman correlation analysis method was used to analyze the correlation between CK-MB and PSS score. Logistic regression model was used to construct joint predictors, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of various indicators for 28-day prognosis of patients with wasp stings. Finally 90 patients were included in the analysis. There were 67 patients survived at 28 days, and 23 dead with the 28-day mortality of 25.6%. APACHE II score, CK-MB and PSS score in the death group were significantly higher than those in the survival group [APACHE II score: 19.7±2.7 vs. 13.7±2.3, CK-MB (U/L): 183 (151, 243) vs. 36 (21, 75), PSS score: 17.7±2.6 vs. 9.3±4.5, all P < 0.01]. The correlation analysis showed that CK-MB and PSS score were positively correlated (r = 0.843, P < 0.01). Logistic regression model fitted CK-MB and PSS score, and Hosmer-Lemeshow test showed that the model fitted well. ROC curve analysis showed that the area under ROC curve (AUC) of CK-MB for predicting 28-day outcome was 0.957, the sensitivity was 91.3%, and the specificity was 88.1%; the AUC of PSS score was 0.908, the sensitivity was 91.3%, and the specificity was 90.8%. The AUC of CK-MB combined with PSS score was 0.964, the sensitivity was 100%, and the specificity was 79.4%, indicating that CK-MB combined with PSS score had higher predictive value and higher sensitivity for 28-day prognosis of patients with wasp sting. High CK-MB level and high PSS score in early stage of wasp sting injury indicate poor prognosis. Both CK-MB and PSS score can be used as predictors for predicting the prognosis of patients with wasp stings. In addition, CK-MB combined with PSS score have greater predictive value.

Electroacupuncture improves learning and memory functions in a rat cerebral ischemia/reperfusion injury model through PI3K/Akt signaling pathway activation.

Electroacupuncture has been widely used to treat cognitive impairment after cerebral ischemia, but the underlying mechanism has not yet been fully elucidated. Studies have shown that autophagy plays an important role in the formation and development of cognitive impairment, and the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway plays an important role in autophagy regulation. To investigate the role played by the PI3K/Akt signaling pathway in the electroacupuncture treatment of cerebral ischemia/reperfusion rat models, we first established a rat model of cerebral ischemia/reperfusion through the occlusion of the middle cerebral artery using the suture method. Starting at 2 hours after modeling, electroacupuncture was delivered at the Shenting (GV24) and Baihui (GV20) acupoints, with a dilatational wave (1-20 Hz frequency, 2 mA intensity, 6 V peak voltage), for 30 minutes/day over 8 consecutive days. Our results showed that electroacupuncture reduced the infarct volume in a rat model of cerebral ischemia/reperfusion injury, increased the mRNA expression levels of the PI3K/Akt signaling pathway-related factors Beclin-1, mammalian target of rapamycin (mTOR), and PI3K, increased the protein expression levels of phosphorylated Akt, Beclin-1, PI3K, and mTOR in the ischemic cerebral cortex, and simultaneously reduced p53 mRNA and protein expression levels. In the Morris water maze test, the latency to find the hidden platform was significantly shortened among rats subjected to electroacupuncture stimulation compared with rats without electroacupuncture stimulation. In the spatial probe test, the number of times that a rat crossed the target quadrant was increased in rats subjected to electroacupuncture stimulation compared with rats without electroacupuncture stimulation. Electroacupuncture stimulation applied to the Shenting (GV24) and Baihui (GV20) acupoints activated the PI3K/Akt signaling pathway and improved rat learning and memory impairment. This study was approved by the Animal Ethics Committee of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine, China (approval No. 8150150901) on March 10, 2016.

Effect of Xiaoji Recipe on stability of carotid artery vulnerable plaque in elderly patients with type 2 diabetes mellitus and type H hypertension

To explore the effect of Xiaoji Recipe on the stability of carotid artery vulnerable plaque in elderly patients with type 2 diabetes mellitus and type H hypertension(Qi-Yin deficiency with phlegm stagnation). From January 2017 to April 2019, in Endocrinology Department for Outpatients and Inpatients of the First Affiliated Hospital of Henan University of Chinese Medicine, 125 elderly patients with type 2 diabetes mellitus and type H hypertension with carotid artery vulnerable plaque(Qi-Yin deficiency with phlegm stagnation) were selected. According to the numerical table method, the patients were randomly divided into the control group(63 cases, including 56 cases completed) and Xiaoji group(62 cases, including 58 cases completed). Both groups were given control diet, hypoglycemic, hypotensive and symptomatic therapies. The control group was given Rosuvastatin Calcium Tablets 20 mg·d~(-1) before sleep. The Xiaojie group were given Ruisuvastatin Calcium Tablets 10 mg·d~(-1) before sleep, plus Xiaoji Recipe at the same time. Both groups were treated for 6 months. The number of vulnerable plaques, carotid intima-media thickness(IMT) and plaque thickness were detected by color Doppler ultrasound before and after treatment, in order to calculate IMT integral and improved Crouse integral. Meanwhile, lipid metabolism indexes, including total cholesterol(TC), triacylglycerol(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C) and lipoprotein a(LPa). And plaque stability indexes, including hypersensitive c-reactive protein(hs-CRP), matrix metalloproteinase-9(MMP-9), oxidized low-density lipoprotein(ox-LDL), Ⅰ type platelet depolymerization protein binding protein base sequence of metalloproteinases(ADAMTS-Ⅰ) and homocysteine(Hcy) were detected. To evaluate the 6-month curative effect on TCM syndrome, the patients were followed up for 6 months for adverse cardiovascular and cerebrovascular events and adverse drug reactions. After 6 months of treatment, the efficacy on Xiaoji group was better than that of the control group(Z=-2.600, P=0.009). The significant efficiency of the Xiaoji group was higher than that of the control group(χ~2=6.039, P=0.014). The total effective rate of the Xiaoji group was higher than that of the control group(χ~2=4.564, P=0.033). The number of vulnerable plaques form indexes(IMT, IMT integral, plaque thickness, improved Crouse integral), blood lipid metabolism indexes(TC, TG, LDL-C, HDL-C, LPa) and plaque stability indexes(hs-CRP, MMP-9, ox-LDL, ADAMTS-Ⅰ, Hcy) were significantly improved than before treatment in both groups of patients(P&lt;0.01). Compared with the control group, the Xiaoji group showed more obvious improvement(P&lt;0.01). The incidence of adverse cardiovascular and cerebrovascular events in the Xiaoji group was lower than that in the control group within 6 months after treatment(χ~2=4.566, P=0.033). The incidence of adverse drug reactions in the Xiaoji group was lower than that in the control group(χ~2=4.465, P=0.035). This indicated that Xiaoji Recipe combined with small-dose Rosuvastatin Calcium(10 mg·d~(-1)) was safe and effective in the treatment of elderly patients of type 2 diabetes mellitus with type H hypertension and vulnerable carotid artery plaque(Qi-Yin deficiency with phlegm stagnation), and superior to the single high-dose Risovastatin Calcium(20 mg·d~(-1)) regimen. It can reverse carotid plaque, and reduce the activity of vulnerable plaque and the incidence of adverse cardiovascular and cerebrovascular events and adverse drug reactions.

Application of Ultimate Oncoplastic Surgery in Breast-Conserving Surgery

ABSTRACT Objective To investigate the application of oncoplastic surgery in breast-conserving surgery. Methods We retrospectively analyzed the clinical data of 103 breast cancer patients who underwent breast-conserving surgery in the First Affiliated Hospital of Henan University. All the patients were female whose tumor volume-to-breast volume ratio was greater than 20%. Fifty-two patients were treated with oncoplastic breast-conversing surgery (observation group), and 51 patients were treated with traditional breast-conserving surgery (control group). The volume of resected tissue, subjective satisfaction with breast shape, objective score of breast shape, and follow-up were compared between the two groups. Results In the observation group, the weight of resected breast tissue was 64.2–172.1 g, with a median of 98.7 g. In the control group, the weight of resected breast tissue was 67.5–175.7 g, with a median of 102.3 g. After 12 months of follow-up, the subjective satisfaction rate and objective score of breast shape in the observation group were significantly better than those in the traditional breast-conserving surgery group (P 0.05). Conclusion Oncoplastic breast-conserving surgery leads to better cosmetic results and a more satisfactory clinical results.

Qualitative study of the psychological experience of COVID-19 patients during hospitalization

BackgroundCoronavirus disease 2019 (COVID-19) continues to spread across the globe, but patient experiences are rarely documented. ObjectiveTo explore the psychology of COVID-19 patients during hospitalization. MethodsA phenomenological and robust sampling approach was employed. Sixteen patients admitted to the First Affiliated Hospital of Henan University of Science and Technology with COVID-19 from 20th January to 1st March 2020 were selected. Data were collected through semi-structured interviews, phone calls, or face-to-face interviews using quarantine measures. Data were analyzed using the Colaizzi method. ResultsThe psychological experience of COVID-19 patients during hospitalization could be summarized into five themes. Firstly, attitudes toward the disease included fear, denial, and stigma during the early stages, which gradually developed into acceptance in the later stages. Secondly, the major source of stress included the viral nature of the disease, quarantine measures, and concerns regarding the health of family members. Thirdly, reactions of body and mind included disease stage-dependent emotional responses, excessive attention to symptoms, rumination, and changes in diet, sleep, and behavior. Fourthly, supportive factors included psychological adjustments, medical care, and family and social support. Finally, the disease resulted in psychological growth and patients viewed problems with gratitude through the cherishing of life, family, bravery, and tenacity. ConclusionCOVID-19 patients gradually changed their attitude toward the disease and displayed emotional responses dependent on the stage of the disease. Negative emotions dominated during the early stages but gradually gave way to mixed positive and negative emotions. Active guidance of psychological growth may therefore promote physical and mental recovery in COVID-19 patients.

Recommendations for respiratory rehabilitation in adults with coronavirus disease 2019.

Coronavirus disease-2019 (COVID-19) is a highly infectious respiratory disease that leads to respiratory, physical, and psychological dysfunction in patients. Respiratory rehabilitation is an important intervention as well as cure for clinical patients. With increased understanding of COVID-19 and the accumulation of clinical experience, we proposed recommendations for respiratory rehabilitation in adults with COVID-19 based on the opinions of frontline clinical experts involved in the management of this epidemic and a review of the relevant literature and evidence. Our recommendations are as follows: 1. for inpatients with COVID-19, respiratory rehabilitation would relieve the symptoms of dyspnea, anxiety, and depression and eventually improve physical functions and the quality of life; 2. for severe/critical inpatients, early respiratory rehabilitation is not suggested; 3. for patients in isolation, respiratory rehabilitation guidance should be conducted through educational videos, instruction manuals, or remote consultation; 4. assessment and monitoring should be performed throughout the respiratory rehabilitation process; 5. proper grade protection should be used following the present guidelines. These recommendations can guide clinical practice and form the basis for respiratory rehabilitation in COVID-19 patients.

Percutaneous Transforaminal Endoscopic Discectomy and Fenestration Discectomy to Treat Posterior Ring Apophyseal Fractures: A Retrospective Cohort Study

ObjectiveTo compare the efficacy and safety of percutaneous transforaminal endoscopic discectomy (PTED) and fenestration discectomy (FD) for posterior ring apophyseal fractures (PRAF).MethodsThis study was a retrospective cohort control study. A total of 96 patients with lumbar PRAF who underwent surgical treatment at the Henan Provincial People's Hospital of Henan University from September 2013 to December 2017 were retrospectively examined, of which 51 were treated by PTED and 45 by FD. The average age of those in the PTED group was 28.24 years, including 38 males and 13 females. The average age of those in the FD group was 28.07 years, with 33 males and 12 females. Operation time, total blood loss, hospitalization days, preoperative and postoperative visual analog scale (VAS), and Oswestry disability index (ODI) scores were evaluated. Modified MacNab criteria were used to evaluate the clinical effect at the last follow‐up.ResultsBoth operations were successful and no serious complications occurred. All patients were followed up for 12–30 (average 16.7 ± 3.2) months, and no patients were lost to follow‐up. No statistically significant difference was found in the mean age and gender between the PTED group and the FD group (P < 0.05). Operation time, total blood loss, and length of hospital stay were significantly lower in the PTED group (87.65 ± 13.15 min, 12.78 ± 4.95 mL, and 6.80 ± 1.67 days, respectively) than in the FD group (114.11 ± 14.39 min, 30.89 ± 7.09 mL, and 11.71 ± 1.98 days, respectively) (P < 0.05). The VAS and ODI scores of the two groups at postoperative day 1 (PTED: 3.82 ± 0.97, 37.73% ± 3.72%; FD: 3.62 ± 1.09, 36.62% ± 3.05%), and at 3 months (PTED: 2.90 ± 1.08, 26.02% ± 2.90%; FD: 3.07 ± 0.99, 27.16% ± 4.02%), 6 months (PTED: 2.31 ± 0.88, 22.53% ± 2.67%; FD: 2.36 ± 0.77, 21.18% ± 3.35%), and the last follow‐up (PTED: 1.90 ± 0.83, 19.88% ± 3.01%; FD: 1.89 ± 0.86, 18.22% ± 3.03%) were significantly different from the preoperative scores (PTED: 6.53 ± 1.00, 55.24% ± 4.54%; FD: 6.78 ± 1.31, 53.56% ± 5.73%) (P < 0.05). The VAS and ODI scores at 3 months postoperatively, 6 months postoperatively, and the last follow up were not significantly different between the two groups (P > 0.05). In the PTED group, 2 patients developed a transient nerve stimulation symptom within 1 day after surgery and 1 patient had recurrence at 3 months after surgery. In the FD group, 2 patients had severe dural ruptures due to adhesion during surgery, 1 patient developed infection complications, and 2 patients relapsed at 2 and 3 months after surgery. At the last follow‐up, the modified MacNab criteria for clinical effect were 93.3% and 94.1% in the FD and PTED groups, respectively.ConclusionWhile PTED has the same efficacy as FD for treating PRAF, it is associated with shorter operation time, less trauma, and quicker recovery.

Determination of potassium sorbate and sorbic acid in agricultural products using THz time-domain spectroscopy**Project supported by the National Natural Science Foundation of China (Grant Nos. 61705061 and 61975053), Key Science and Technology Program of Henan Province of China (Grant Nos. 182102110204 and 192102110047), Key Scientific and Research Project of Educational Committee of Henan Province of China (Grant No. 19B510001), and

The aim of this study was to investigate the feasibility of detecting potassium sorbate (PS) and sorbic acid (SA) in agricultural products using THz time-domain spectroscopy (THz-TDS). The absorption spectra of PS and SA were measured from 0.2 to 1.6 THz at room temperature. The main characteristic absorption peaks of PS and SA in polyethylene and powdered agricultural products with different weight ratios were detected and analyzed. Interval partial least squares (iPLS) combined with a particle swarm optimization and support vector classification (PSO-SVC) algorithm was proposed in this paper. iPLS was used for frequency optimization, and the PSO-SVC algorithm was used for spectrum analysis of the preservative content based on the optimal spectrum ranges. Optimized PSO-SVC models were obtained when the THz spectrum from the PS/SA mixture was divided into 11 or 12 subintervals. The optimal penalty parameter c and kernel parameter g were found to be 1.284 and 0.863 for PS (0.551–1.487 THz), 1.374 and 0.906 for SA (0.454–1.216 THz), respectively. The preliminary results indicate that THz-TDS can be an effective nondestructive analytical tool used for the quantitative detection of additives in agricultural products.

A qualitative study on the psychological experience of caregivers of COVID-19 patients

BackgroundThe coronavirus disease 2019 (COVID-19) is spreading rapidly, bringing pressure and challenges to nursing staff.ObjectiveTo explore the psychology of nurses caring for COVID-19 patients.MethodsUsing a phenomenological approach, we enrolled 20 nurses who provided care for COVID-19 patients in the First Affiliated Hospital of Henan University of Science and Technology from January 20, to February 10, 2020. The interviews were conducted face-to-face or by telephone and were analysed by Colaizzi's 7-step method.ResultsThe psychological experience of nurses caring for COVID-19 patients can be summarized into 4 themes. First, negative emotions present in early stage consisting of fatigue, discomfort, and helplessness was caused by high-intensity work, fear and anxiety, and concern for patients and family members. Second, self-coping styles included psychological and life adjustment, altruistic acts, team support, and rational cognition. Third, we found growth under pressure, which included increased affection and gratefulness, development of professional responsibility, and self-reflection. Finally, we showed that positive emotions occurred simultaneously with negative emotions.ConclusionsDuring an epidemic outbreak, positive and negative emotions of the front-line nurses interweaved and coexisted. In the early stage, negative emotions were dominant and positive emotions appeared gradually. Self-coping styles and psychological growth played an important role in maintaining mental health of nurses.

Objective To analyze the neurodevelopmental characteristics of the children with methylmalonic acidemia and investigate its possible influencing factors. Methods The clinical questionnaire was used to collect clinical data of children with methylmalonic acidemia at the First Affiliated Hospital of Henan University of Chinese Medicine from February 2016 to February 2018, and Gesell development scal was used to evaluate the neurodevelopment. Results Among the 86 patients, 45 cases were boys and 41 cases were girls.They were 2.4 to 62.5 months, and the minimum age was 8.3 months.Thirty-three cases were detected by neonatal screening, 53 cases were diagnosed after onset.The energy zone in this children were mild to severe developmental defects.Twenty-eight cases were 0 to 6 months old, and fine exercise, the large exercise and adaptability developmental defects were significant of them; 24 cases were >6 to 12 months old, and the language, adaptability and personal-social developmental defects were significant of them; 23 cases were >12 to 36 months old, and the language, adaptability and large movements developmental defects were significant of them; 11 cases aged >36 to 72 months had significant developmental defects in language, personal-social contact and adaptability.The developmental quotients of fine movements, big movements, adaptability, personal-social and language of the children diagnosed by newborn screening were much better than those diagnosed after onset in each energy zone(all P<0.05). Conclusions Although the treatment is actively regulated, most children with methylmalonic acidemia still have neurodevelopmental abnormalities with varying degrees of severity.The children before the age of 6 months have significant defects in motor movement and adaptability development.The patients after the age of 6 months usually have language, adaptability and social contact defects.Newborn screening is important and nervous system damage is milder in the children diagnosed by newborn screening.

Transjugular intrahepatic portosystemic shunt combined with agitation thrombolysis in treatment of acute portal vein thrombosis

Objective To study the clinical efficacy of transjugular intrahepatic portosystemic shunt (TIPS) combined with agitation thrombolysis in treatment of acute portal vein thrombosis (PVT) in patients with liver cirrhosis. Methods The clinical data of 37 cirrhotic patients with acute PVT treated from January 2014 to December 2017 at the First Affiliated Hospital of Henan University of Science and Technology was analyzed. There were 20 males and 17 females with age ranging from 29 to 71 years. The patients were divided into the combined group (n=15) and the anticoagulation group (n=22). The combined group was treated with TIPS combined with agitation thrombolysis anticoagulation. The anticoagulation group was treated with anticoagulation. The changes in liver function and hemodynamics of portal vein of the two group were compared. Follow-up studies included postoperative portal vein patency, bleeding and survival rates of patients. Results The postoperative portal vein pressure and maximum burden of PVT in the combined group were significantly lower than those before operation, and the portal vein maximum blood volume and flow velocity of portal vein were significantly higher than those before operation (all P<0.05). At 2 weeks, 6 months and 12 months after operation, the maximum burden of PVT of the combined group was (13.9±5.4)%, (16.1±5.5)% and (13.8±6.2)%, respectively, which was significantly lower than that of the anticoagulant group (84.1±31.3)%, (85.9±27.6)% and (88.2±39.5)% (all P<0.05). At 2 weeks, 6 months and 12 months after operation, the flow velocity of portal vein of the combined group was (21.6±5.7) cm/s, (16.1±6.3) cm/s and (17.6±4.9) cm/s, respectively, which was significantly higher than that of the anticoagulation group (9.7±4.6) cm/s, (8.1±4.3) cm/s and (8.2±3.5) cm/s (all P<0.05). After operation, 3 patients in the combined group developed recurrence of portal vein thrombosis, while the remaining patients had smooth blood flow in the portal vein and shunt. In the anticoagulation group, only 3 patients had unobstructed portal vein blood flow. The cumulative rate of no gastrointestinal bleeding in the combined group was significantly better than the anticoagulant group. The cumulative survival rate of the combined group was also significantly better than the anticoagulation group (P<0.05). Conclusion TIPS combined with agitation thrombolysis was more effective than the traditional anticoagulant therapy in treatment of acute portal vein thrombosis in cirrhotic patients.
