Objective:To evaluate the effect of low-dose esketamine for postoperative analgesia on the postoperative depression in patients with gastrointestinal tumors.Methods:This study was a prospective randomized controlled trial. Eighty patients, aged 18-64 yr, with a body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective radical resection of the gastrointestinal tumor under general anesthesia from June to November 2023 in our hospital, were divided into 2 groups ( n=40 each) using a random number table method: esketamine group (group E) and control group (group C). Each patient received postoperative patient-controlled intravenous analgesia(PCIA). The PCIA solution in group E contained esketamine 0.5 mg/kg, dezocine 0.5 mg/kg, dexmetomidine 1.5 μg/kg and flurbiprofen ester 100 mg in 100 ml of normal saline. The PCIA solution in group C contained dezocine 0.5 mg/kg, dexmetomidine 1.5 μg/kg and flurbiprofen ester 100 mg in 100 ml of normal saline. The Hospital Anxiety and Depression Scale (HADS) was used to assess the patients′ anxiety and depression at 1 day before operation (T 0) and 2 days after operation (T 1). The Quality of Recovery-15 scale was used to evaluate the early postoperative recovery quality. Visual analog scale scores, the pressing times of patient-controlled analgesia and the number of rescue analgesia were recorded within 2 days after operation. The occurrence of drug-related adverse reactions was also recorded. Results:Seventy-eight patients were finally included, with 39 cases in group E and 39 cases in group C. Compared with group C, the postoperative HADS-depression scale score and incidence of depression were significantly decreased, the Quality of Recovery-15 scale score was increased, the visual analog scale scores were decreased ( P<0.05), and no significant changes were found in the postoperative HADS-anxiety scale score and incidence of anxiety, the pressing times of patient-controlled analgesia and the number of rescue analgesia in group E ( P>0.05). Visual hallucination was found at 1 day after operation in one patient and relieved at 2 days after operation in group E. There was no significant difference in the incidence of postoperative dizziness, nausea and vomiting between the two groups ( P>0.05). Conclusions:Postoperative analgesia with 0.5 mg/kg esketamine can alleviate postoperative depressive symptoms, enhance the efficacy of analgesia and improve the early postoperative recovery quality in patients with gastrointestinal tumors.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

Objective:To evaluate the effect of intravenous infusion of dexmedetomidine before induction of anesthesia on concentrations of blood potassium and blood glucose in the patients with gastrointestinal tumors.Methods:One hundred and twenty patients, irrespective of gender, aged 18-75 yr, with body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, scheduled for elective radical gastrointestinal tumor surgery, were divided into 3 groups ( n=40 each) using a random number table method: control group (group C), dexmedetomidine 0.5 μg/kg group (group D 1), and dexmedetomidine 1.0 μg/kg group (group D 2). Dexmedetomidine 0.5 and 1.0 μg/kg were intravenously infused prior to anesthesia induction over 10 min in D 1 and D 2 groups, while the equal volume of normal saline 20 ml was intravenously infused instead in group C. Before intravenous infusion (T 0), at 15 min after intravenous infusion (T 1), and at 30 min after intravenous infusion (T 2), blood samples from the radial artery were collected for blood gas analysis, and concentrations of blood potassium and blood glucose were recorded. The occurrence of complications such as hyperglycemia, hypoglycemia, hyperkalemia, hypokalemia, hypotension, hypertension, tachycardia and bradycardia was also recorded. Results:Compared with C group, the blood glucose concentrations were significantly increased at T 1 in D 1 and D 2 groups and at T 2 in D 2 group ( P<0.05). The blood glucose concentrations were significantly higher at T 1, 2 in D 2 group than in D 1 group ( P<0.05). There was no significant difference in blood potassium concentrations at T 0-T 2 among the three groups ( P>0.05). No patients presented with complications such as hyperglycemia, hypoglycemia, hyperkalemia, hypokalemia, hypotension, hypertension, tachycardia and bradycardia. Conclusions:Intravenous infusion of dexmedetomidine before induction of anesthesia exerts no marked effect on blood potassium concentrations and can increase glucose concentrations to a certain extent, but the elevation has no clinical significance in the patients with gastrointestinal tumors.

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.

Objective To explore the theories, content and approaches of integrating physical activity in children's eye health service system in the context of health services. Methods From the perspectives of six building blocks of WHO health system, namely, leadership and governance, financing, human resources for health, service delivery, medical technology, and health information system, we analyzed the policy framework and key contents related to school-based eye health and physical activity, and explored how to promote the implementation of physical activity into the school-based eye health service system, and the integration of physical activity into the eye health continuum: prevention, intervention, rehabilitation, and health promotion. Results In perspective of health system, the integration of physical activity into school-based eye health services should be in accordance with the five principles of cross-cutting health services, namely, universal accessibility and equity, human rights, evidence-based, life-span, and empowerment. According to the World Vision Report, WHO advocates to build a person-centered eye health service system, and person-centeredness is the core concept of the new model of school-based eye health services and physical activity integration. WHO advocates a school-based approach to education and physical activity in health-promoting schools to promote student health, physical activity as a preventive, interventional, rehabilitation and health promotive measure related to children's eye health, and vigorously train professionals within schools who have knowledge and skills related to physical activity and eye health, build an information system on physical activity and children's eye health, and promote the integration of physical activity into the school-based eye health service system. Conclusion Physical activity is an important measure to promote children's eye health and an important component to achieve a person-centered eye health service system. Based on the six building blocks of the WHO health service system, a school-based eye health service that integrates a theoretical and methodological system of physical activity is constructed, requiring the provision of health promotion methods such as education and physical activity in the school setting, to enhance leadership and governance of eye health services based on educational and physical activity approaches in the school setting, establish new funding mechanisms, provide financial security, develop human resources related to physical activity for eye health, improve related service delivery systems, develop high-quality physical activity intervention eye health techniques and equipment, and integrate information on children's physical activity and eye health into school health information systems to achieve children's eye health and promote their physical and mental development.

INTRODUCTION: The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) on the risk of malignancy (ROM) in fine-needle aspiration cytology (FNAC) per The Bethesda System for Reporting Thyroid Cytopathology has not been well reported in Singapore. METHODS: We retrospectively identified 821 thyroid nodules with preoperative FNAC from 788 patients out of 1,279 consecutive thyroidectomies performed between January 2010 and August 2016 in a tertiary general hospital in Singapore. Possible cases of NIFTP were reviewed for reclassification and the impact of NIFTP on ROM was analysed. RESULTS: The incidence of NIFTP was 1.2% (10 out of 821). If NIFTP is considered benign, ROM in Bethesda I through VI were 8.6%, 3.5%, 26.3%, 20.0%, 87.7%, 97.0% versus 8.6%, 4.2%, 28.1%, 26.7%, 89.2% and 100% if NIFTP is considered malignant. Eight patients with NIFTP had follow-up of 15 to 110 months. One had possible rib metastasis as evidenced by I131 uptake but remained free of structural or biochemical disease during a follow-up period of 110 months. None had lymph node metastasis at presentation, nor locoregional or distant recurrence. CONCLUSION Classifying NIFTP as benign decreased ROM in Bethesda II through VI, but the benignity of NIFTP requires more prospective studies to ascertain. The impact of NIFTP on ROM in our institution also appears to be lower than that reported in the Western studies.

Non-alcoholic steatohepatitis (NASH) is an important link for the progression of metabolic-related fatty liver disease to end-stage liver disease such as cirrhosis and hepatocellular carcinoma, which seriously endangers human health. NASH pathogenesis is complex, and involves the interaction between hepatic parenchymal and non-parenchymal cells (NPCs), sinusoidal endothelial cells, Kupffer cells, hepatic stellate cells, and so on. Herein, the relevant research progress of NPCs in the pathogenesis of NASH is reviewed in order to further understand the role of NPCs in NASH.

A method was established for simultaneous determination of 21 active constituents including flavanols, isoflavones, flavonols, dihydroflavones, dihydroflavonols, chalcones, pterocarpan, anthocyanidins and phenolic acids in Spatholobi Caulis by ultra fast liquid chromatography with triple quadrupole linear ion trap mass spectrometry(UFLC-QTRAP-MS/MS). Then, it was employed to analyze and evaluate the dynamic accumulation of multiple bioactive constituents in Spatholobi Caulis. The chromatographic separation was performed on a XBridge®C_(18)(4.6 mm×100 mm, 3.5 μm) at 30 ℃ with a gradient elution of 0.3% formic acid aqueous solution-methanol, and the flow rate was 0.8 mL·min~(-1), using multiple-reaction monitoring(MRM) mode. A comprehensive evaluation of the multiple bioactive constituents was carried out by gray correlation analysis(GRA). The 21 target components showed good linearity(r>0.999 0) in the range of the tested concentrations. The average recovery rates of the 21 components were from 97.46% to 103.6% with relative standard deviations less than 5.0%. There were differences in the contents of 21 components in Spatholobi Caulis at diffe-rent harvest periods. Spatholobi Caulis had high quality from early November to early December, which is consistent with the local tradi-tional harvest period. This study reveals the rule of the dynamic accumulation of 21 components in Spatholobi Caulis and provides basic information for the suitable harvest time. At the same time, it provides a new method reference for the comprehensive evaluation of the internal quality of Spatholobi Caulis.

Objective:To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China.Methods:A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014.Results:Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade Ⅱ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively.Conclusions:The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.
