OBJECTIVE: To observe the effect of perioperative transcutaneous electrical acupoint stimulation (TEAS) on postoperative fatigue syndrome (POFS) in elderly patients undergoing laparoscopic radical gastrectomy. METHODS: A total of 80 elderly patients scheduled for laparoscopic radical gastrectomy were randomized into a TEAS group and a sham TEAS group, 40 cases in each one. In the TEAS group, TEAS intervention was applied at bilateral Hegu (LI4), Neiguan (PC6), Zusanli (ST36) and Sanyinjiao (SP6) from 30 min before anesthesia induction until surgery completion, and at 18:00 on 1st, 2nd and 3rd days after surgery, once a day, 30 min a time. In the sham TEAS group, the same acupoints were selected and connected to the electroacupuncture device at the same time, without electrical stimulation. One day before surgery and 1, 3, 7 days after surgery, the 10-item short form of identity consequence fatigue scale (ICFS-10) score was observed, and the POFS incidence rate of 1, 3, 7 days after surgery was assessed in the two groups. One day before surgery, surgery completion, and 1, 3 days after surgery, the serum levels of superoxide dismutase (SOD), β-endorphin (β-EP) were detected; 1 day before surgery and 1, 3, 7 days after surgery, the serum level of tumor necrosis factor-α (TNF-α) was detected in the two groups. The pain visual analog scale (VAS) score was observed at 24, 48 and 72 h after surgery; the intraoperative dosage of propofol and remifentanil, and the incidence rate of postoperative nausea and vomiting, itching, respiratory depression were recorded in the two groups. RESULTS: In the TEAS group, on 1, 3, 7 days after surgery, except for the scores of item 8-10, the item scores and the total scores of ICFS-10 were lower than those in the sham TEAS group (P<0.001); on 3 and 7 days after surgery, the POFS incidence rates were lower than those in the sham TEAS group (P<0.05). In the TEAS group, on 1 and 3 days after surgery, the serum levels of SOD were higher than those in the sham TEAS group (P<0.05, P<0.01); at surgery completion, and on 1, 3 days after surgery, the serum levels of β-EP were higher than those in the sham TEAS group (P<0.001, P<0.01); on 1, 3, 7 days after surgery, the serum levels of TNF-α were lower than those in the sham TEAS group (P<0.01, P<0.001). In the TEAS group, at 24, 48 and 72 h after surgery, the pain VAS scores were lower than those in the sham TEAS group (P<0.001, P<0.01, P<0.05); the intraoperative dosage of remifentanil was lower than that in the sham TEAS group (P<0.001); the incidence rate of postoperative nausea and vomiting was lower than that in the sham TEAS group (P<0.01). CONCLUSION Perioperative TEAS intervention can effectively reduce the incidence rate of POFS, improve fatigue symptom and mental state in elderly patients undergoing laparoscopic radical gastrectomy, its mechanism may related to enhancing endogenous β-EP release, inhibiting inflammatory response, and reducing central oxidative stress, thereby promoting postoperative recovery.

Objective:To evaluate the effect of low-dose esketamine on intraoperative electroencephalogram (EEG) burst suppression under general anesthesia in elderly patients.Methods:In this prospective randomized controlled trial, 86 elderly patients of either sex, scheduled for elective lumbar fusion surgery at Anhui No. 2 Provincial People′s Hospital from March 15 to June 1, 2024, aged 60-85 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification ⅡorⅢ, were divided into 2 groups ( n=43 each) using a random number table method: esketamine group (group S) and control group (group C). In group S, esketamine at a dose of 0.25 mg/kg was intravenously injected after anesthesia induction, while the equal volume of normal saline was intravenously injected in group C. The occurrence of EEG burst suppression and frequency of the characteristic density spectral array were recorded using the Masimo Sedline cerebral function monitor. The patient state index was recorded before esketamine administration and at 5, 10, 30 and 60 min after administration and at 5 min before the end of the surgery. Delirium was assessed using the Confusion Assessment Method at 1 and 3 days after operation. The total pressing times of patient-controlled analgesia within 48 h after operation, requirement for rescue analgesia and occurrence of adverse reactions (nausea and vomiting, delayed emergence from anesthesia, agitation, headache) were recorded. The consumption of ephedrine, phenylephrine, sufentanil and remifentanil during operation, emergence time, time of tracheal extubation, length of stay in the post-anesthesia care unit, and length of postoperative hospital stay were also recorded. Results:Compared with group C, the incidence of EEG burst suppression and frequency of the characteristic density spectral array were significantly decreased, the patient state index values were increased at each time point after administration and 5 min before the end of surgery, the consumption of ephedrine, phenylephrine, sufentanil and remifentanil during operation was reduced, the effective pressing times of patient-controlled analgesia, rate of rescue analgesia, and incidence of postoperative delirium within 3 days after operation were decreased, and the length of postoperative hospital stay was shortened in group S ( P<0.05). Conclusions:Low-dose esketamine can reduce intraoperative EEG burst suppression and decrease the development of postoperative delirium under general anesthesia in elderly patients.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the evidence-based practice of prevention and care of nasal and facial pressure injuries in patients with non-invasive positive pressure ventilation (NPPV) using the knowledge to action framework (KTA), and to explore its effectiveness.Methods:Using an evidence-based nursing approach, an evidence-based practice group was established to formulate a clinical problem, the literature from domestic and international databases were researched for relevant evidence, the evidence was introduced into clinical scenarios, an evidence-based practice plan was developed, and a strategy for applying the best evidence was constructed by conducting a baseline review of healthcare professionals and patients with NPPV, analyzing barriers and promoting factors, and making changes in clinical practice at the organizational level, the practitioner level, and the patient level. Purposive sampling method was used to select the healthcare staff of the cardiac surgical intensive care unit (CSICU) of the Shandong Provincial Hospital Affiliated to Shandong First Medical University, as well as the patients with NPPV admitted from October 1 to November 15, 2023 (pre-evidence-based practice) and November 16 to December 31 (post-evidence-based practice), as the subjects of the study. Through questionnaire analysis, the incidence of nasal and facial pressure injury of NPPV patients, the implementation rate of review indicators of medical staff, the score of the knowledge, belief and conduct of medical staff, and the compliance and comfort of patients before and after evidence-based practice were compared.Results:A total of 52 medical staff were included, aged (28.54±6.50) years old, with 3.00 (1.00, 12.75) years of working experience; 2 doctoral degree holders (3.85%), 4 master degree holders (7.69%), 46 bachelor degree holders (88.46%); 2 with senior title (3.85%), 17 with intermediate title (32.69%), and 33 junior titles (63.46%). Fifty patient questionnaires were collected before and after evidence-based nursing practice; the differences between before and after evidence-based practice in terms of gender, age, body weight, duration of ventilator usage, 24-hour bleeding and total bleeding were not statistically significant and were comparable. Compared with the pre-evidence-based practice, after carrying out the corresponding evidence-based nursing practice, the incidence of nasal and facial pressure injuries of NPPV patients decreased from 16.00% (8/50) to 4.00% (2/50, P < 0.05), the total implementation rate of review indicators of medical staff increased from 79.73% to 94.08% ( P < 0.01), and the total scores of knowledge, belief and conduct were significantly improved (141.96±13.88 vs. 114.65±19.72, P < 0.05), and compliance and comfort of patients were significantly improved (compliance score: 4.60±0.99 vs. 5.82±1.42, comfort score: 4.10±1.63 vs. 6.92±2.33, both P < 0.05]. Conclusion:The application of an evidence-based nursing approach to obtain evidence related to the prevention of nasal and facial pressure injuries in patients with NPPV can be used to guide clinical practice, significantly reducing the incidence of nasal and facial pressure injuries in such patients, improving the implementation rate of review indicators and the knowledge, belief, and conduct scores of medical staff, and enhancing compliance and comfort of NPPV patients.

Background: Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. Methods: Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. Results: The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. Conclusion The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

Objective: To systematically review the diagnostic accuracies of multiplex real time polymerase chain reaction (MRT-PCR) technique for detection of respiratory syncytial virus (RSV) and adenovirus (ADV). Methods: PubMed, EMBASE, Cochrane, Wanfang and CNKI databases were searched from January1 2010 to January1 2018, to collect reports on MRT-PCR for detection of common respiratory viruses. Then two authors independently exacted the data and assessed the risk of bias of included studies by using the QUADAS-2 tool. Meta-disc 1.4. Results: Ten articles with 2528 cases were eligible for analysis. The result of meta-analysis showed that, the pooled Sen, Spe and area under SROC curve, for detecting RSV were 0.87 (95% CI 0.83 to 0.90), 0.98 (95% CI 0.97 to 0.98) and 1.00. The pooled Sen, Spe, and area under SROC curve of MRT-PCR for detecting ADV were 0.64 (95% CI 0.56 to 0.71), 0.99 (95% CI 0.98 to 0.99) and 0.99. Deeks test indicated that no publication bias was found. Conclusions The sensitivity of MRT-PCR in RSV and ADV detection is still to be improved, but the overall detection ability is good which deserves to be recommended for clinical use.

Objective To observe the effects of dexmedetomidine (DEX) on the expressions of TNF-α, IL-1β and apoptosis-related proteins in rat mesenteric artery.Methods Male SD rats of SPF grade were sacrificed and the mesenteric artery was separated under the stereo-microscope.We established an experimental model of vascular injury induced by lipopolysaccharide (LPS) and randomly divided the injured vessels into dexmedetomidine treatment group and control group.DEX treatment group was divided into 10-8, 10-7, and 10-6 mol/L subgroups according to the different concentrations of DEX.RNA and total protein was extracted in each group.The mRNA expressions of TNF-α, IL-1β and CaSR were detected by RT-PCR and the protein expression of TNF-α, Caspase-3 and AMPK were tested by Western blot.Results DEX (10-8, 10-7, and 10-6mol/L) obviously reduced vascular inflammatory reaction induced by lipopolysaccharide, reduced the mRNA and protein expressions of TNF-α as well as mRNA expression of IL-1β.Caspase 3 protein expression significantly lowered in blood vessels in DEX group compared with LPS group.DEX had no obvious effect on lipopolysaccharide-induced vascular AMPK and CaSR mRNA or protein expressions.Conclusion DEX obviously deceased the expressions of inflammation-related proteins, suggesting that DEX has anti-inflammatory effects.
