The content determination results of the 5 components in three batches of Xuetong capsules were （0.632-0.641）, （0.660-0.681）, （1.968-1.991）, （2.547-2.580）, and （1.076-1.101） mg/g. Conclusion The method was accurate, reproducible, and highly feasible, which could be references for producing and improving the quality control standards of Xuetong capsules.

The repair of the nervous system after hypoxic-ischemic brain damage (HIBD) in neonates lacks specific therapeutic approaches, posing a challenge and hot topic in the medical field. Autophagy, as a cellular self-repair mechanism, plays a role through different signaling pathways at different stages, yet its specific roles and mechanisms in different stages of HIBD remain unclear. This article reviews the recent research advancements on autophagy in different neonatal HIBD stages: heightened autophagic activity manifests during the acute hypoxic-ischemic phase, with its neuroprotective or deleterious impact subject to ongoing debate; during the subacute and chronic phases, autophagy exert dual effects on neuronal death and repair; in sequelae period, autophagy-related studies are still insufficient, but the expression levels of autophagy-related genes (ATG) in children with cerebral palsy suggest both positive and negative aspects of autophagy post-HIBD. Collectively, optimal autophagic flux facilitates the elimination of detrimental substrates and toxic proteins, thereby engendering neuroprotection. Further studies on the roles and mechanisms of autophagy in HIBD therapy holds promise for devising efficacious preventative and therapeutic strategies rooted in autophagy, and to improve the survival rate and quality of life of the children.

Objective To evaluate the effectiveness and safety of Yiyang Pill in preventing and treating cardiovascular adverse reactions in patients with traditional Chinese medicine(TCM)syndrome with qi and yin deficiency and thyroid stimulating hormone(TSH)inhibition after differentiated thyroid cancer(DTC)resection.Methods A randomized,double-blind,placebo-controlled clinical trial was conducted,and 120 patients with TSH inhibition after DTC surgery were enrolled and randomized into two groups in a 1∶1 ratio using SAS 9.4 software generated random tables.The control group received a placebo and TSH suppression therapy,whereas the treatment group received the Yiyang Pill and TSH suppression therapy.The treatment period was 3 months.The incidence of cardiovascular adverse reactions,blood pressure,blood lipids,thyroid function,the dosage of levothyroxine,the efficacy of TCM syndrome,and safety indicators were compared between the two groups.Multivariate Logistic regression was used to analyze the influencing factors of cardiovascular adverse reactions.Results The incidence of cardiovascular adverse reactions in the treatment group was lower than that in the control group(P<0.05),and the efficacy of TCM syndrome treatment was significantly higher than in the control group(P<0.05).The free tetraiodothyronine level in the treatment group was higher than that before treatment(P<0.05),and the systolic and diastolic blood pressure in the control group increased compared to those before treatment(P<0.05).No severe adverse events were observed in either group.Compared with the control group,the cardiovascular incidence in the treatment group was lower,and the cardiovascular incidence in the<100 μg/d group was lower than that in the group with≥100 μg/d before treatment.Conclusion The Yiyang Pill can reduce the incidence of cardiovascular adverse reactions in patients after DTC surgery,effectively improve TCM syndromes,and be safe to use.Yiyang Pill treatment is a protective factor for cardiovascular adverse reactions,and the dosage of levothyroxine≥100 μg/d was a risk factor.

Objective:To explore the effect of knowledge-clinical-sharing (KCS) model in humanistic care training of pediatric nurses.Methods:A total of 182 specialist nurses who were trained in Hunan Children's Hospital from June 2019 to December 2019 were selected as the research objects. Among them, 102 specialist nurses from June 2019 to August 2019 were selected as the control group, and 80 specialist nurses from September 2019 to December 2019 were selected as the intervention group. The Jefferson empathy scale was used to compare the effect of humanistic training before and after the implementation. SPSS 22.0 statistical software was used, measurement data were test by F-test and t-test, and the counting data were analyzed by Chi-square test. Results:After the implementation of humanistic care training based on KCS model, the empathy ability score of the intervention group was higher than that of the control group [(80.23±5.33) vs. (78.14±4.37)], and the difference was statistically significant ( P < 0.01). There was no significant difference between neonatal and pediatric specialist nurses before and after the training. Conclusion:The phased humanistic training based on KCS model can improve the empathy ability of pediatric nurses and enhance their confidence in the clinical implementation of humanistic care. However, the humanistic training mode of pediatric nurses should be improved according to the hospital's own situation, so as to adapt to the development of nursing industry.

Objective     To analyze the clinical efficacy and survival outcome of totally thoracoscopic redo mitral valve replacement and evaluate its efficiency and safety. Methods     The clinical data of patients with totally thoracoscopic redo mitral valve replacement in Guangdong Provincial People’s Hospital between 2013 and 2019 were retrospectively analyzed. Survival analysis was performed using the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were used to determine the risk factors for postoperative death. Results     There were 48 patients including 29 females and 19 males with a median age of 53 (44, 66) years. All the procedures were performed successfully with no conversion to median sternotomy. A total of 15, 10 and 23 patients received surgeries under non-beating heart, beating heart and ventricular fibrillation, respectively. The in-hospital mortality rate was 6.25% (3/48), and the incidence of early postoperative complications was 18.75% (9/48). Thirty-five (72.92%) patients had their tracheal intubation removed within 24 hours after the operation. The 1- and 6-year survival rates were 89.50% (95%CI 81.30%-98.70%) and 82.90%(95%CI 71.50%-96.20%), respectively. Age>65 years was an independent risk factor for postoperative death (P=0.04). Conclusion     Totally thoracoscopic redo mitral valve replacement is safe and reliable, with advantages of rapid recovery, reducing blood transfusion rate, reducing postoperative complications and acceptable long-term survival rate. It is worthy of being widely popularized in the clinic.

Constructing a doctor-patient community with a shared future requires efforts from both the medical supply side and the patient demand side, with special attention to the needs of patients. Continuously meeting and improving the needs of patients is the starting point, ultimate goal, and evaluation standard for constructing a doctor-patient community with a shared future. Therefore, this paper proposed the proposition of "what patients need", that is, what needs do patients have and how to meet their needs. The fundamental needs of patients are to diagnose and treat diseases and recover from illness, which are specifically manifested in the demands to narrate the disease’s feelings, the willingness to participate in medical decision-making, the experience of diagnosis and treatment in the process of medical treatment, and the satisfaction evaluation of the hospital’s performance appraisal. On the basis of clarifying the needs of patients, this paper proposed the paths and methods to meet patients’ needs, and provided new ideas for constructing a doctor-patient community with a shared future.

Multifactor analysis results showed that being rural resident ( OR=1.99, 95% CI: 1.78-2.23), being woman ( OR=1.76, 95% CI: 1.57-1.97), 65-75 years old ( OR=1.21, 95% CI: 1.03-1.45), senior high school and technical secondary school education level ( OR=1.38, 95% CI: 1.17-1.63), annual family income >100 000 yuan ( OR=1.65, 95% CI: 1.20-2.26), overweight ( OR=9.27, 95% CI: 8.26-10.41), obesity ( OR=82.82, 95% CI: 62.63-109.52), normal high blood pressure ( OR=1.49, 95% CI: 1.27-1.74), hypertension ( OR=1.70, 95% CI: 1.42-2.04), diabetes ( OR=2.30, 95% CI: 1.94-2.73), dyslipidemia ( OR=1.33, 95% CI: 1.18-1.50) were positively related to the risk for central obesity and pre central obesity. Conclusions:The prevalence rates of central obesity and pre central obesity in residents in Jilin were at high levels, being rural resident, being woman, older age, senior high school and technical secondary school education level, high income, overweight and obesity, normal high blood pressure and hypertension, diabetes, dyslipidemia were risk factors for central obesity and pre-central obesity in Jilin.

Objective    To evaluate the efficacy of hybrid ablation through compared with thoracoscopic epicardial ablation. Methods    In this study, 108 patients with all long-standing persistent atrial fibrillation (LSPAF) received thoracoscopic epicardial ablation (TEA) after enrollment. There were 82 males and 26 females at age of 56.5±9.4 years. After blanking-period, patients off antiarrhythmic therapy with sinus rhythm were divided into a hybrid ablation (HA) group (50 patients) and a TEA group (58 patients). Only patients in the HA group received catheter ablation after randomization subsequently. In at least two-year observation period, cardiovascular risk factors were observed in all groups’ patients. Results    The mean follow-up duration was 17.3-41.8 (26.9±6.1) months and there was no significant difference between two groups [8.2-40.6 (27.5±5.7) months in the HA group and 17.3-41.8 (26.4±6.7) months in the TEA group]. The off antiarrhythmic agents (AADs) sinus rhythm rate was significantly higher in the HA group than that in the TEA group at the time of postoperative 6, 12, 24 and 36 months ［96.0%, 90.0%, 83.7%, 83.7% versus 79.3%, 75.9%, 67.3%, 63.1%, HR=0.415 (95%CI 0.206-0.923)]. Conclusion    We can conclude that the efficacy of two-staged hybrid ablation for LSPAF is superior to thoracoscopic epicardial ablation alone. Patients can obtain benefit from a supplemental radiofrequency catheter ablation after blanking-period of surgical ablation, instead of those without a supplemental ablation.

Objective:To perform principal component analysis on the status quo of nurses' research ability, and explore the status quo of their relevant research needs.Methods:In this cross-sectional study, totally 588 clinical nurses working in a children's hospital in Hunan Province from July to December 2019 were selected by stratified random sampling and investigated with the self-designed questionnaire. The survey content included three parts: the first part was general information; the second part was the survey of the status quo of nurses' research ability; the third part was the survey of the status quo of nurses' research needs. A total of 588 questionnaires were distributed, and 577 questionnaires were collected, accounting for an effective recovery rate of 98.13%.Results:The three items with the higher scores in the survey of research ability status were frequently search for professional materials through the Internet (3.255±0.491) scores, able to perform statistical description (2.931±0.572) scores and able to use Chinese database (2.894±0.429) scores. The three items with the higher need for research ability were project application 80.94% (467/577) , paper writing 76.95% (444/577) and special lecture 71.92% (415/577) , whereas the three items with the lower need for research ability were continuing learning 46.10% (266/577) , retrieving documents 40.90% (236/577) and group symposium 38.30% (211/577) .Conclusions:Nursing staff has relatively good ability in information retrieval and basic statistics, but relatively poor ability in paper writing. The research ability of nurses can be summarized as statistical analysis ability, information retrieval/document reading ability, research topic selection ability and paper writing ability. Attention should be paid to whether there are high research needs in the weak links of research ability, and nursing research guidance and education should be provided purposively.
