Objective: To investigate the humanistic care consciousness and ability of outpatient and emergency nurses in tertiary Grade A hospitals in Zhengzhou City. Methods: In June 2021, a total of 345 outpatient and emergency nurses from 6 tertiary Grade A hospitals in Zhengzhou City were selected as the survey objects by random number table method. The humanistic care ability of outpatient and emergency nurses was investigated. Multiple linear regression analysis was used to analyze the related factors influencing the humanistic care ability of outpatient and emergency nurses. Results: The total score of humanistic care ability of outpatient and emergency nurses in Zhengzhou tertiary Grade A hospital was (194.18±30.53). The scores of humanistic care ability of outpatient and emergency nurses with different gender, age, educational background, professional title, length of service, night shift frequency, marital status, children's status, employment patterns and average monthly household income were significantly different (P<0.05). Regression analysis showed that education background, length of service, professional title and night shift frequency were independent influencing factors for outpatient and emergency nurses' humanistic care ability (β=0.243, 0.139, 0.163, -0.126, P<0.05) . Conclusion: At present, the humanistic care ability of outpatient and emergency nurses in tertiary Grade A hospitals in Zhengzhou City is still low. Education, length of service, professional title and night shift frequency are independent influencing factors affecting the humanistic care ability of nurses.

Prevalence, patterns and prognosis of multimorbidity among middle-aged and elderly inpatients with chronic obstructive pulmonary disease / 中华预防医学杂志

Objective: To explore the characteristics, patterns of multimorbidity and the impact on quality of life and the prognosis of middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD). Methods: This is a cross-sectional study. From January 2012 to December 2021, 939 middle-aged and elderly COPD patients hospitalized in Beijing Hospital were selected by the convenient sampling method. The basic data of patients and the date of 16 common chronic diseases were collected. Patterns of multimorbidity were depicted by cluster analysis. Generalized linear regression model and logistic regression were used to evaluate the multimorbidity patterns and their prognosis. Results: At least one multimorbidity existed among 93.40% of COPD patients, and the median number of multimorbidity was 3. The top five multimorbidity among the patients were hypertension (57.93%, 544/939), coronary heart disease (33.76%,317/939), heart failure (31.95%,300/939), hyperlipidemia (31.63%,297/939) and arrhythmia (27.37%,257/939). Four multimorbidity patterns were identified, cardiometabolic and metabolic multimorbidity, kidney disease multimorbidity, respiratory-digestive-tumor multimorbidity and other multimorbidity. Cardiometabolic and metabolic multimorbidity was most common (590/939, 62.83%). Compared with non-cardiometabolic and metabolic multimorbidity, the incharge ADL score of patients with this multimorbidity decreased by 7 points (95%CI:-11.22- -3.34), Correspondingly, patients with kidney disease multimorbidity decreased by 14 points (95%CI:-24.12- -3.30) on the incharge score. The presence or absence of kidney disease multimorbidity had the greatest impact on discharge score, which was reduced by 12 points in comparison with patients without this multimorbidity (95%CI:-22.43- -2.40). ICU admission is mostly affected by the presence of cardiometabolic and metabolic multimorbidity (OR=2.44, 95%CI: 1.51-3.92) and kidney disease multimorbidity (OR=2.58, 95%CI: 1.01-6.60). The risk of death is the highest for cardiometabolic and metabolic multimorbidity (OR=2.24, 95%CI: 1.19-4.21). Conclusion: Multimorbidity is common in COPD patients. The most common pattern is cardiometabolic and metabolic multimorbidity. Cardiometabolic and metabolic multimorbidity and kidney disease multimorbidity significantly affect the quality of life and often associate with a poor prognosis.

Clinical Comparison of the Efficacy of Systemic Thrombolysis,Catheter-Directed Thrombolysis,and AngioJet Percutaneous Mechanical Thrombectomy in Acute Lower Extremity Deep Venous Thrombosis / 中国医学科学院学报

Objective To compare the clinical effects of three treatment methods including systemic thrombolysis(ST),catheter-directed thrombolysis(CDT),and AngioJet percutaneous mechanical thrombectomy(PMT)in acute lower extremity deep venous thrombosis(LEDVT). Methods The data of 82 patients diagnosed with LEDVT in the Department of Vascular and Gland Surgery of the First Affiliated Hospital of Hebei North University from January 2017 to December 2020 were collected.The patients were assigned into a ST group(n=50),a CDT group(n=16),and a PMT group(n=16)according to different treatment methods.The efficacy and safety were compared among the three groups. Results Compared with that before treatment,the circumferential diameter difference of both lower limbs on days 1,2,and 3 of treatment in the ST,CDT,and PMT groups reduced(all P<0.001).The PMT group showed smaller circumferential diameter difference of lower limbs on days 1,2,and 3 of treatment than the ST group(all P<0.001)and smaller circumferential diameter difference of the lower patellar margin on day 1 of treatment than the CDT group(P<0.001).The PMT group showed higher diminution rate for swelling of the affected limb at the upper and lower edges of the patella than the ST group(P<0.001)and higher diminution rate for swelling at the upper edge of the patella than the CDT group(P=0.026).The incidence of complications after treatment showed no significant differences among the three groups(all P>0.05).The median of hospital stay in the PMT group was shorter than that in the ST and CDT groups(P=0.002,P=0.001).The PMT group had higher thrombus clearance rate than the ST group(P=0.002)and no significant difference in the thrombus clearance rate from the CDT group(P=0.361).The vascular recanalization rates in the PMT(all P<0.001)and CDT(P<0.001,P=0.002,P=0.009)groups 3,6,and 12 months after treatment were higher than those in ST group,and there were no significant differences between PMT and CDT groups(P=0.341,P=0.210,P=0.341). Conclusions ST,CDT,and PMT demonstrated significant efficacy in the treatment of LEDVT,and PMT was superior to ST and CDT in terms of circumferential diameter difference of the lower limbs,diminution rate for swelling of the affected limb,thrombus clearance rate,length of hospital stay,and long-term vascular recanalization.There was no obvious difference in safety among the three therapies.

CiteSpace knowledge map analysis of Angong Niuhuang Pills in recent twenty years / 中国中药杂志

Angong Niuhuang Pills, a classical formula in traditional Chinese medicine, are lauded as one of the "three treasures of febrile diseases" and have been widely used in the treatment of diverse disorders with definite efficacy. However, there is still a lack of bibliometric analysis of research progress and development trend regarding Angong Niuhuang Pills. Research articles on Angong Niuhuang Pills in China and abroad(2000-2022) were retrieved from CNKI and Web of Science. CiteSpace 6.1 was used to visualize the key contents of the research articles. In addition, the research status of Angong Niuhuang Pills was analyzed by information extraction to allow insight into the research trends and hotspots about Angong Niuhuang Pills. A total of 460 Chinese articles and 41 English articles were included. Beijing University of Chinese Medicine and Sun Yat-Sen University were the research institutions that have published the largest amount of research articles in Chinese and English. The keyword analysis showed that the Chinese articles focused on cerebral hemorrhage, stroke, neurological function, coma, cerebral infarction, craniocerebral injury, and clinical application, while the English articles focused on the mechanisms of cerebral ischemia, stroke, heavy metal, blood-brain barrier, and oxidative stress. Stroke, blood-brain barrier, and oxidative stress were presumably the research hotspots in the future. At present, the research on Angong Niuhuang Pills is still in the developing stage. It is necessary to highlight the in-depth research on the active components and mechanism of action and carry out large-scale randomized controlled clinical trials to provide references for the further development and application of Angong Niuhuang Pills.

Effect of fluoxetine combined with Shugan Jieyu capsule in the treatment of patients with depression and its impact on heart rate variability / 四川精神卫生

BackgroundDepression is a kind of disease with relatively high suicide risk， which seriously affects the quality of life of patients and their families， and brings a great burden to society. Antidepressants in western medicine are effective， but the improvement of depressive symptoms is relatively limited by single use， and the combination of two antidepressants may increase the risk of adverse reactions in patients. The rational use of Chinese patent medicine and western medicine may play a complementary role， and the safety of Chinese patent medicine is high. ObjectiveTo explore the early clinical efficacy of fluoxetine combined with Shugan Jieyu capsule in the treatment of depression， and to compare the differences in efficacy， safety and influence on heart rate variability between fluoxetine combined with Shugan Jieyu capsule and fluoxetine alone， so as to provide references for clinical medication of depression patients. MethodsFrom December 2015 to June 2016， 64 patients who met the diagnostic criteria of depression in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） who were hospitalized in the Second Affiliated Hospital of Xinxiang Medical University were selected as the research objects， and were randomly divided into the combined medication group and the fluoxetine group with 32 patients in each group. Patients in both groups were treated with fluoxetine， while patients in the combined medication group were treated with Shugan Jieyu capsule on this basis. Patients in both groups were assessed with Hamilton Depression Scale-24 item （HAMD-24）， Hamilton Anxiety Scale （HAMA） and Heart Rate Variability （HRV） before treatment， and were assessed with HAMD-24 and Treatment Emergent Symptom Scale （TESS） at the end of the 2nd， 4th and 6th week of treatment， and HRV was analyzed again at the end of the 6th week of treatment. ResultsThe study ultimately included 60 patients with depression， with 30 cases in the combination therapy group and 30 cases in the fluoxetine group. At the end of the 2nd， 4th and 6th week of treatment， the HAMD-24 score of the combined drug group was lower than that of the fluoxetine group （t=-2.677， -3.960， -4.432， P<0.05 or 0.01）. Compared with before treatment， the 24-hour mean standard deviation of normal RR intervals （SDNN）， normal low frequency （nLF） and normal high frequency （nHF） in the combined treatment group were higher at the end of the 6th week （t=-73.970， -31.878， -38.721， P<0.01）， but significant lower in LF/HF （t=3.525， P<0.01）. At the end of the 6th week of treatment， the total effective rate of the combined treatment group was higher than that of fluoxetine group， and the difference was statistically significant （86.67% vs. 70.00%， χ2=18.764， P<0.01）. At the 2nd， 4th and 6th week of treatment， there was no significant difference in the number of adverse reactions between the two groups （P>0.05）. ConclusionCompared with fluoxetine alone， Shugan Jieyu capsule combined with fluoxetine may be better in clinical efficacy and improvement of heart rate variability in patients with depression， without increasing adverse reactions.

Effects of clinical application of free anterolateral thigh perforator lobulated flap in repair of electrical burn wounds on head based on the concept of donor site protection / 中华烧伤杂志

Objective: To explore the effects of clinical application of free anterolateral thigh perforator lobulated flap in repair of electrical burn wounds on head based on the concept of donor site protection. Methods: A retrospective observational study was conducted. Eight patients with electrical burns with huge scalp defects and exposed skulls were admitted to the First Affiliated Hospital of Zhengzhou University, from May 2017 to December 2019, who were all males, aged 21-57 (39±13) years, sustaining multiple deep partial thickness to full-thickness electrical burns to 5%-14% total body surface area. Among the scalp burn sites of the patients, 1 case was posterior occipital, 2 cases were parietal occipital, 4 cases were parietal temporal, and 1 case was frontotemporal. After debridement, the defect area was 10 cm×9 cm-16 cm×14 cm. The incision area of the free anterolateral thigh perforator lobulated flap was 22 cm×6 cm-30 cm×9 cm. The artery and vein of flap were anastomosed with superficial temporal artery and vein or facial artery and vein, and the other vein of skin flap was anastomosed with superficial vein of recipient area. The donor site of skin flap was closed by layer interrupted tension-reducing suture. After the operation, the survival of flop, donor site wound healing and complications were observed. The flap appearance, wound healing of donor sites, long-term complications and functional recovery of donor sites were observed on follow-up. Results: After the operation, the flaps of 8 patients survived completely without vascular crisis. The donor sites of flaps in all the patients healed well with no osteofascial compartment syndrome. Seven patients were followed up for 3 to 12 months, and 1 case was lost to follow up. During follow-up, the flaps of the patients' heads were in good appearance but with alopecia. The donor sites showed linear scars, which were well hidden. There were no significant differences in sensory and motor functions between the two sides, and no complications were found such as muscle hernia. Conclusions: Free anterolateral thigh perforator lobulated flap has a good clinical effect in the early repair of electrical burn wounds with huge scalp defect and skull exposure on head, and the donor wounds can be directly closed and sutured, greatly reducing the damage to the donor area.

Cross-sectional study of association between dietary pattern and cognitive performance in people aged 50 and above years in Shanghai / 中华流行病学杂志

Objective: To investigate the association between dietary pattern and cognitive performance in local residents aged ≥50 years in Shanghai. Methods: Data were obtained from the second round of Study of Global Ageing and Adult Health (SAGE) survey in Shanghai. Dietary patterns were surveyed by factor analysis. Cognitive tests were conducted to assess subjects' cognitive performance, including verbal recall, verbal fluency and digit test. Multiple linear regression analysis was used to evaluate the relationship between dietary patterns and cognition performance. Results: A total of 4 132 subjects with complete dietary and cognitive performance test data were included. Factor analysis was used to obtain three dietary patterns: including plant-based pattern, high animal-food pattern, high salt-oil pattern. After controlling for gender, age, education level and other factors, it was found that plant-based pattern (β=0.26,95%CI: 0.17-0.36) and high animal-food pattern (β=0.18, 95%CI:0.06-0.29) were positively associated with total cognitive test score while high salt-oil pattern (β=-0.28, 95%CI:-0.85--0.07) was negatively associated with verbal fluency test score. Conclusion: A dietary pattern with high intake of plant food and appropriate intake of animal food might be associated with better cognitive function of residents aged ≥50 years.

Effects of electroacupuncture with different frequencies on hippocampal neuronal apoptosis and JNK signaling pathway in rats with vascular dementia / 针灸推拿医学（英文版）

Objective: To observe the effects of electroacupuncture (EA) with three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) on the apoptosis of neurons and c-Jun N-terminal kinase (JNK) signaling pathway in the hippocampus of rats with vascular dementia (VD), and explore the mechanism of EA intervention for VD. Methods: Fifty male Sprague-Dawley rats were randomly divided into a model group, a sham operation group, a 100 Hz EA group, a 2 Hz EA group, and a 2 Hz/100 Hz EA group, with ten rats in each group. The VD model rats were established by repeated ischemia-reperfusion of bilateral common carotid arteries. The rats in the EA groups received EA intervention at Baihui (GV20), Dazhui (GV14), Geshu (BL17) and Zusanli (ST36), once a day for 14 d. Afterward, Morris water maze was used to examine the learning and memory performances of the rats in each group, hematoxylin-eosin staining to observe the histomorphological changes in the hippocampal CA1 region, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling to test the apoptosis of neurons in the hippocampal CA1 region, and Western blot to detect the protein expression levels of JNK, phosphorylated JNK (p-JNK), Caspase-8, and Caspase-3 in the hippocampus tissue. Results: Compared with the sham operation group, the escape latency of the model group in water maze test was prolonged; the number of crossing the original platform was decreased (P<0.01); the hippocampal neurons were severely damaged and the number of surviving neurons was decreased (P<0.01), whereas the number of apoptotic neurons was increased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were significantly increased (P<0.01). Compared with the model group, the escape latency of each EA group was significantly shortened; the number of crossing the original platform was significantly increased (P<0.01); the damage of hippocampal neurons was alleviated, the number of surviving neurons was increased (P<0.01), and the number of apoptotic neurons was decreased (P<0.01); the protein expression levels of JNK, p-JNK, Caspase-8, and Caspase-3 in the hippocampus were decreased (P<0.01). The results in the 2 Hz EA group and the 2 Hz/100 Hz EA group were superior to those in the 100 Hz EA group. Conclusion: EA with the three frequencies (100 Hz, 2 Hz, and 2 Hz/100 Hz) can improve the learning and memory performances in VD rats subjected to ischemia-reperfusion, its mechanism may be related to the inhibition of neuronal apoptosis and the regulation of the related protein expression of JNK signaling pathway, and the intervention effects of EA with 2 Hz and 2 Hz/100 Hz are more significant.

Research Progress of Disease Developmental Process and Disease Dynamic Molecular Network Construction of "Myocardial Infarction-heart Failure" / 中国实验方剂学杂志

With the development of omics technology， the construction of disease networks has been widely used in the study of complex diseases. It has been widely used to construct disease networks using systems biology technology to study complex diseases. The mechanism exploration model of disease molecular network which uses the method of constructing disease networks， simulates the occurrence of diseases， explores the core development mechanism of complex diseases， and then predicts biomarkers and exploits the mechanism of drug action provided many new thoughts for the prevention and treatment of complex diseases. Nowadays， the research on the mechanism of myocardial infarction caused by myocardial ischemia and heart failure after myocardial infarction is still very important. However， the research of the molecular network of myocardial infarction and heart failure diseases is usually limited to a few targets and pathways， so it is not able to comprehensively and systematically explain the disease process. Furthermore， authors outlined the typical biological process of "myocardial infarction-heart failure" and related targets from the pathophysiological level， and summarized the existing methods of constructing dynamic networks for heart diseases and other diseases. Based on the dynamic molecular network construction methods of cardiac diseases and other diseases， this paper discusses the construction of the dynamic molecular network of myocardial infarction and heart failure， in order to understand the evolution of myocardial infarction and heart failure more accurately and explore the importance of the dynamic molecular network of the disease process for the study of disease mechanism.

Analysis of Crucial Transcription Factors of Berberine Against Cerebral Ischemia Based on Transcriptomics and Proteomics / 中国实验方剂学杂志

ObjectiveOn the basis of determining the protective effect of berberine （BBR） on cerebral ischemia， crucial transcription factors （TFs） of BBR against cerebral ischemia was identified by using transcriptome and proteome sequencing. MethodThe model of middle cerebral artery occlusion （MCAO） was established by thread embolization. The sham operation group， model group， low-dose group of BBR （dose of 37.5 mg·kg-1·d-1） and high-dose group of BBR （75 mg·kg-1·d-1） were set up. The rats were killed after continuous intragastric administration for 7 days. The pharmacodynamics was evaluated by Longa score and cerebral infarction rate， and the expressions of inflammatory cytokines， such as interleukin （IL）-1β， tumor necrosis factor （TNF）-α and monocyte chemotactic protein-1 （MCP-1） were measured by enzyme-linked immunosorbent assay （ELISA）. Then， RNA-Seq technique was used to detect the differentially expressed genes （DEGs） before and after BBR intervention， and DAVID 6.8 was used for enrichment analysis of DEGs. CatTFREs technique was used to detect differential TFs before and after BBR intervention， and DAVID 6.8 and STRING 11.0 were used for enrichment analysis and TFs association analysis. Finally， by integrating the activity of TFs and the changes of downstream target genes， crucial TFs were identified and the related regulatory network was constructed by Cytoscape 3.7.1. ResultCompared with the sham operation group， the neurological impairment was significant in the model group （P<0.01）， and compared with the model group， the low and high dose BBR groups could significantly reduce the neurological function damage （P<0.01） and decrease the rate of cerebral infarction （P<0.01）. Transcriptome data analysis showed that BBR was involved in the recovery process after cerebral ischemia mainly by affecting cell adhesion， brain development， neuron migration， calcium signaling pathway， cyclic adenosine monophosphate （cAMP） signaling pathway， inflammatory response and other related functions and signaling pathways. Proteomic data analysis showed that the differentially expressed TFs after BBR intervention interfered with cerebral ischemia mainly by regulating cell differentiation， immune system process， cell proliferation and other biological processes. In addition， integration analysis of TFs and DEGs revealed that transcription factor CP2-like 1 （TFCP2L1）， nuclear factor erythroid-2 like 1 （NFE2L1）， neurogenic differentiation protein 6 （NeuroD6） and POU domain， class 2， transcription factor 1 （POU2F1） were crucial TFs against cerebral ischemia-reperfusion injury mediated by BBR. ConclusionBBR has obvious protective effect on cerebral ischemia-reperfusion injury and its crucial TFs include TFCP2L1， NFE2L1， NeuroD6 and POU2F1.

Shoulder MRI evaluation of the association of os acromiale with supraspinatus and infraspinatus injury / 中国骨伤

OBJECTIVE@#To explore the MRI findings of os acromiale and to analyze the relationship between os acromiale and the supraspinatus and infraspinatus injury.@*METHODS@#From January 2010 to August 2020, 21 patients with os acromiale (os arcomiale group) were compared with 21 subjects with no evidence of os acromiale (no os arcomiale group). There were 14 males and 7 females in the os arcomiate group, aged from 29 to 77 years old, mean aged (55.5±11.5) years old. While in the control group, there were 10 males and 11 females in no os arcomiale group, aged from 31 to 70 years old, mean aged (51.1±10.0) years old. The os acromiales were classified as edematous os acromiale or non-edematous os acromiale based on whether the presence of marrow edema, and as displaced os acromiale or non-displaced os acromiale based on whether the presence of displacement of the os acromiale. The MRI features of os acromiale were analyzed. Statistical analyses were performed to identify the differences between the os arcomiale group and no os arcomiale group regarding rotator cuff tear, supraspinatus and infraspinatus injury. Differences in the supraspinatus and infraspinatus tear between the edematous and non-edematous os acromiale group, the displaced and non-displaced os acromiale group, the displaced os acromiale and no os arcomiale group were also assessed.@*RESULTS@#On MRI, all the 21 os acromiales appeared as a triangular or irregular bone fragment of the distal acromion, and forms a pseudo-acromioclavicular joint with the acromion. Eleven cases were edematous os acromiale, 11 cases were displaced os acromiale. In the os arcomiale group, 17 had supraspinatus tear, 1 had supraspinatus tendinitis, 11 had infraspinatus tear, and 4 had infraspinatus tendinitis. In the no os arcomiale group, 11 had supraspinatus tear, 2 had supraspinatus tendinitis, 5 had infraspinatus tear, and 1 had infraspinatus tendinitis. No statistically significant difference between the os arcomiale group and no os arcomiale group regarding the rotator cuff tear, supraspinatus and infraspinatus injury (P>0.05). In the 11 cases of edematous os arcomiale, 10 had supraspinatus tear and 7 had infraspinatus tear. In the 10 cases of non-edematous os acromiale, 7 had supraspinatus tear and 4 had infraspinatus tear. No statistically significant difference was noted between the edematous os acromiale and non-edematous os acromiale in terms of supraspinatus and infraspinatus tear (P>0.05). In the 11 cases of displaced os acromiale, 11 had supraspinatus tear and 9 had infraspinatus tear. In the 10 cases of non-displaced os acromiale, 6 had supraspinatus tear and 2 had infraspinatus tear. In the no os arcomiale group, 11 had supraspinatus tear and 5 had infraspinatus tear. There was a statistically significant increases in the prevalence of supraspinatus and infraspinatus tear in the displaced os acromiale group compared with non-displaced os acromiale group, the displaced os acromiale group and no os arcomiale group(P<0.05).@*CONCLUSION@#Shoulder MRI can very well depict os acromiale and can reveal associated abnormalities such as adjacent bone marrow edema, displaced deformity, and rotator cuff tear, and it can be used to assess the stability of the os acromiale. The presence of os acromiale may not increase the risk of supraspinatus and infraspinatus tear significantly. However, the presence of displaced os acromiale is at greater risk of supraspinatus and infraspinatus tear.

The influence of scene dialogue on the experience of blood donors during blood donation / 中国输血杂志

【Objective】 To explore the effect of repeated use of situational dialogues in the process of blood donation of voluntary blood donors. 【Methods】 From September to November 2019, blood donors in the center were investigated in the form of questionnaire, and the influencing factors of blood donation experience were analyzed by regression analysis.The direction of blood donation service should be improved according to the influencing factors.Compared with the survey data before and after the improvement, the effectiveness of the new blood donation service measures, centering on the situation dialogue, on improving blood donation experience was evaluated. 【Results】 A total of 304 and 187 valid questionnaires were returned from the two surveys. Regression analysis of the data from the first study revealed that the main factors affecting the blood donation experience were emotion, value, body and service. The regression coefficient for emotional experience was 2.587 (OR=13.292). Based on this evidence, improvements were implemented to the blood donation service, and the core strategy was to increase emotional communication with blood donors through multiple situational dialogues to achieve psychological support for blood donors. The results of the comparison of the data before and after the measure were as follows: emotional experience 3.490±0.879 vs. 3.754±0.771, value experience 3.461±0.957 vs. 3.722±0.854, and service experience 3.355±0.908 vs. 3.663±0.909; all were improved (F=9.365~23.025, P<0.01 for all). The control analysis illustrated that the improved orientation of the blood donation service was effective in improving the donor experience (χ2=4.776, P<0.05). 【Conclusion】 Increasing verbal situational dialogues with blood donors is an effective way for blood centers to improve donors′ donation experience, which helps donors to develop a positive evaluation of blood donation and leads to an increased intention to return.

Value of high resolution magnetic resonance imaging for preoperative evaluation of Denonvilliers fascia in patients with rectal cancer / 中华胃肠外科杂志

Objective: Total mesorectal excision (TME) is the gold standard for surgical treatment of mid-low rectal cancer, but the postoperative incidence of urination and sexual dysfunction is relatively high. Preserving the Denonvilliers fascia (DF) during TME can reduce the postoperative incidence of urination and sexual dysfunction. In this study, high resolution magnetic resonance imaging (MRI) was used to observe the imaging performance and display of DF, so as to determine the value of this technique in preoperative evaluation of the preservation of DF. Methods: A descriptive cohort study was carried out. Clinical data of patients with rectal cancer who underwent TME and received preoperative high-resolution MRI at department of Gastrointestinal Surgery, the Third Affiliated Hospital of Sun Yat-sen University from August 2015 to June 2017 were retrospectively analyzed. The characteristics of DF were examined, and the shortest distance (d) between the anterior edge of tumor and DF was measured on high-resolution MRI. The distance d was compared between patients with stage T1-T2 and those with stage T3. Receiver operating characteristic (ROC) analysis was used to determine the predictive value of d for stage T1-T2 disease. Results: Thirty-two patients were enrolled in the study, including 27 males and 5 females with mean age of (62.9±8.9) years. DF was visualized in 96.9% (31/32) of cases on the T2WI sequence. The mean distance d in patients with stage T1-T2 disease (n=23) was (6.73±2.65) mm, and in those with stage T3 disease (n=9) was (1.30±1.15) mm (t=5.893, P<0.001). A cutoff of d >3 mm yielded specificity and positive predictive value for diagnosing stage T1-T2 disease of both 100%, sensitivity of 95.7% and negative predictive value of 90%. The optimum threshold of d was >3.05 mm, and Youden index was 0.957. Conclusions: High-resolution MRI can show the DF and accurately evaluate the relationship of DF with tumor in rectal cancer patients. Analysis on d value can provide an objective basis for the safe preservation of DF.

Objective:To determine the application effect of the "full chain" information-based health management model in the home care of children with bronchial asthma.Methods:Sixty children with bronchial asthma who were hospitalized in the Respiratory Department of Xuzhou Children's Hospital from January to June 2020 were selected and divided into a control group and an observation group according to a random number table with 30 cases in each group. The control group received routine nursing care, and the observation group implemented a "full-chain" informatized health management on the basis of the control group.The intervention time was 6 months. The condition control, medication compliance, self-management and airway function were observed and compared between the two groups.Results:After 6 months of intervention, the frequency of attacks, emergency cases, the medication compliance, the maximum expiratory flow rate, symptom days and peak expiratory flow days were 6.67%(2/30), 3.33%(1/30), 93.33%(28/30), (1.83±0.23) L, (163.00±6.74) d, (168.00±3.78) d in the observation group, and 26.67%(8/30), 20.00%(6/30), 66.67%(20/30), (1.67±0.24) L, (144.00±5.88) d, (157.00±4.08) d in the control group. The differences were statistically significant (χ 2 values were 4.320, 4.043, 6.667, t values were 2.636, 11.635, 10.833, P<0.05). There was no significant difference in the ratio of forced expiratory volume and forced expiratory volume in forced vital capacity in the first second after 6 months of intervention between the two groups ( P>0.05). Conclusions:"Full chain" information health management can reduce the number of attacks and emergency visits of children with asthma, effectively improve medication compliance, thus improving airway function and improving the quality of life of children.

Value of ultrasonography in diagnosis of closed volar plate injury of proximal interphalangeal joint / 中华超声影像学杂志

Objective:To evaluate the role of high frequency ultrasonography in diagnosis of closed volar plate injury of proximal interphalangeal joint.Methods:From May 2015 to may 2021, 41 patients with acute closed volar plate injury confirmed by Department of Hand and Foot Surgery of the Provincial Hospital Affiliated to Shandong First Medical University were examined by high frequency ultrasonography. The sonographic features were analyzed and classified.Results:High frequency ultrasonography could not only clearly show the thickness, shape and echo of volar plate, but also the degree of injury and avulsion fracture of volar plate, according to which the closed volar plate injury could be divided into three types: A, B and C. Type A(13 cases): Avulsion fracture of the middle phalangeal base was found with volar plate rupture, the sonogram showed that the continuity of the volar plate attachment of the middle phalangeal base was interrupted, and avulsion fracture was found at the distal end of the volar plate. Type B(11 cases): Complete rupture of the volar plate attachment of the middle phalangeal base was found without avulsion fracture, the sonogram showed that the continuity of the volar plate attachment of the middle phalangeal base was interrupted, and the end of the volar plate contracted and thickened. Type C(17 cases): Tear of the volar plate was found, the sonogram showed enlarging volar plates, heterogeneous internal echo, and liquid dark area was visible in some cases. The average thickness of the three types of closed volar plate injury of the proximal interphalangeal joint measured by ultrasound was (0.33±0.05)cm, and the average thickness of the volar plate at the same position of the corresponding finger on the opposite side was (0.22±0.03)cm. There was significant difference between the two groups ( t=7.864, P=0.006). Conclusions:High frequency ultrasonography is the preferred imaging examination method for the diagnosis of closed volar plate injury in proximal interphalangeal joint, which has an important guiding significance for the selection of clinical treatment.

Corilagin inhibits SARS-CoV-2 replication by targeting viral RNA-dependent RNA polymerase

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become one major threat to human population health. The RNA-dependent RNA polymerase (RdRp) presents an ideal target of antivirals, whereas nucleoside analogs inhibitor is hindered by the proofreading activity of coronavirus. Herein, we report that corilagin (RAI-S-37) as a non-nucleoside inhibitor of SARS-CoV-2 RdRp, binds directly to RdRp, effectively inhibits the polymerase activity in both cell-free and cell-based assays, fully resists the proofreading activity and potently inhibits SARS-CoV-2 infection with a low 50% effective concentration (EC

Effect of family-of-origin paternal parenting on father involvement of 1-12 years old children: the mediating effect of role perception and moderating effect of depression / 中华行为医学与脑科学杂志

Objective:To identify the distal and proximal influencing factors of father involvement, and explore the mediating role of father's role perception and the moderating role of depression in the effect of his family-of-origin paternal parenting on father involvement.Methods:Totally 572 fathers with children aged under 12 years old completed the father involvement questionnaire, role of the father questionnaire (ROFQ), parental bonding instrument (PBI) and the center for epidemiologic studies depression scale (CES-D). The Pearson correlation analysis and non-parametric percentile Bootstrap method were conducted via SPSS 21.0.Results:(1)Father involvement (2.86±0.58) was found to be negatively correlated with his own family-of-origin paternal indifference (7.30±3.86) ( r=-0.175, P<0.01), positively correlated with his family-of-origin paternal care (10.46±3.98) ( r=0.291, P<0.01), negatively correlated with his depression (7.07±5.09) ( r=-0.266, P<0.01) and positively correlated with his role perception (61.52±5.92) ( r=0.522, P<0.01). (2)Father's role perception partially mediated the relationship between his family-of-origin paternal care and his own paternal involvement (the mediating effect was 0.015, which was 35.71% of the total effects) and fully mediated the relationship between his family-of-origin paternal indifference and his own paternal involvement (the mediating effect was -0.016). (3)Father's depression played a moderating role between his family-of-origin paternal care and his own role perception ( β=-0.069, P<0.05). And it also played a moderating role between his family-of-origin paternal indifference and his own role perception ( β=0.121, P<0.001). The results of J-N methods showed that the values and significance of simple slopes varied according to father's depression levels in both two models. Conclusion:The paternal parenting that fathers had experienced in his family of origin is an important factor affects his own paternal involvement.In the relationship between father's family-of-origin paternal parenting and his own paternal involvement, father's role perception plays a mediating role and his depression level plays a moderating role.

Application of clinical flow examination scale in standardized residency training of anesthesiology / 中华医学教育探索杂志

Objective:The clinical flow examination (CFE) scale was used to evaluate the effect of standardized residency training in the department of anesthesiology in West China Hospital of Sichuan University.Methods:Using the CFE scale, 98 students were tested three times consecutively, and then satisfaction surveys were conducted on the assessment tutors and students respectively. IBM SPSS software was used to test the reliability and validity of the CFE scale, and then the scores and satisfaction were statistically analyzed. SPSS 23.0 was used for t test and chi-square test. Results:The CFE scale had high reliability and validity, and the results of 95 students were included for analysis. The 95 students had a very high rate of excellence in basic, professional and final grades. Except that the basic, professional and final overall scores of the female group were higher than those of the male group ( P < 0.05), the differences between the other groups were not statistically significant ( P > 0.05). Results of the CFE satisfaction survey showed that the satisfaction of students and instructors was 98.9% and 100%, respectively. Conclusion:CFE scale can be well used to evaluate the effect of standardized residency training, and the training effect of anesthesiology department in our hospital is good and basically homogeneous, while there is still room for further improvement.
