Based on the opening-closing-pivot theory， this paper proposes that adolescent bipolar disorder is closely associated with taiyin （太阴）， shaoyang （少阳）， and jueyin （厥阴） channels. The principal pathogenesis involves dysfunction of the opening function of taiyin， impaired pivot function of shaoyang， and failure of the closing function of jueyin. Accordingly， the therapeutic principles include regulating taiyin to restore the ascending and descending movement of qi， harmonizing shaoyang to facilitate the pivot mechanism， and balancing yin and yang to reinforce the closing and storing function of jueyin. In clinical practice， Yihuang Powder （益黄散） and Tongxie Important Formula （痛泻要方） are commonly prescribed to regulate the qi movement of taiyin and restore its ascending and transporting functions， while Xiaochaihu Decoction （小柴胡汤） and Sini Powder （四逆散） are used to regulate the shaoyang pivot， and Wumei Pill （乌梅丸）， Danggui Sini Decoction （当归四逆汤）， and Huanglian Ejiao Decoction （黄连阿胶汤） combined with Shaoyao Gancao Decoction （芍药甘草汤） are employed to harmonize the jueyin closing mechanism. In addition， traditional daoyin （导引） exercise yi jin jing （易筋经） is incorporated to simultaneously regulate the body and mind by guiding internal regulation through external movement， thereby calming the body and tranquilizing the mind.

Background The decline of physical activity in the elderly due to aging may increase the risk of sarcopenia. Currently, there is a lack of evidence from large natural populations on the relationship between PA and sarcopenia. Objective To explore the relationship between PA and sarcopenia in the elderly aged 60 years and above in 10 provinces (autonomous regions) of China. Methods Data were retrieved from the 2022—2023 round of the China Development and Nutrition Health Impact Cohort. Personal basic information and PA data were collected by questionnaire survey. Skeletal muscle mass was measured by bio-electrical impedance analysis, muscle strength was measured using a grip dynamometer, and physical performance was reflected by 6-meter walk speed. The Asian Working Group for Sarcopenia (AWGS) 2019 criteria were used to diagnose sarcopenia. Light physical activity (LPA) duration, moderate-to-vigorous physical activity (MVPA) duration, and total physical activity volume were calculated. A total of 3326 residents aged ≥60 years with complete data were selected as the survey participants. Multiple logistic regression models and restricted cubic splines (RCS) were used to assess the association between PA duration/volume and sarcopenia. Results In 10 provinces (autonomous regions) of China, the prevalence of sarcopenia in the elderly aged 60 years and above was 5.5% (95%CI: 4.7%, 6.2%). The logistic regression analysis showed that compared with the elderly reporting 0-7.0 h·week⁻¹ in LPA duration, the risk of sarcopenia in the elderly with LPA duration of >14.0-21.0 h·week⁻¹ was reduced by 51% (OR=0.49, 95%CI: 0.26, 0.96). Compared with the elderly with total physical activity ≥15.0 metabolic equivalent of task (MET)-h·week⁻¹, those with <7.5 MET-h·week⁻¹ had a 2.24-fold increased risk of sarcopenia (OR=2.24, 95%CI: 1.17, 4.29). The RCS results found that LPA duration and total physical activity volume each showed a nonlinear dose-response relationship with the risk of sarcopenia (P_overall<0.05, P_non-linear<0.05). Compared with the elderly with an LPA duration of 0 h· week⁻¹, the risk of sarcopenia in the elderly with an LPA duration of 12.6 h· week⁻¹ was the lowest (OR=0.42, 95%CI: 0.21, 0.83). Compared with the elderly with a total physical activity volume of 15.0 MET-h· week⁻¹, the elderly with a total physical activity volume of 46.0 MET-h· week⁻¹ had the lowest risk of sarcopenia (OR=0.57, 95%CI: 0.38, 0.84). There was no statistically significant association between weekly MVPA duration and the risk of sarcopenia (P>0.05). Conclusion Increasing weekly LPA duration and total physical activity volume would help to reduce the risk of sarcopenia.

Objective To explore the challenges faced by online appointment nurses during nasogastric intubation and to provide a reference for improvement of the quality and safety of the services provided by online appointment nursing.Methods A purposive sampling was employed to select 13 online appointment nurses from our hospital who had previously provided home nasogastric intubation services for patients.Semi-structured interviews were conducted with the online appointment nurses.The results acquired from the interviews were analysed using Colaizzi's method.Results Two themes were identified.Theme 1 covered the increased risks of nasogastric intubation due to the patients themselves and home environment,which included 4 sub-themes of difficulties in identification and response due to complex conditions of patient,high risk of a sudden asphyxia with poor resuscitation facility,psychological stress from unfamiliar home environment,and more challenges in risk identification due to limited conditions for performing home-based intubation procedures;Theme 2 covered the coping strategies of online-scheduled nurses,which included the improvement of knowledge and skills in emergency nursing to improve comfidence and judge ability of intubation,the strengthening of nurse-patient communication to build a trust and cooperation,the conduct of thorough assessment to ensure procedural safety,and the use of alternative tools and collaboration with family members.Conclusion Online appointment nurses face challenges and risks from both of the procedures and patients themselves during home based nasogastric intubation.Hospitals and relevant management should actively implement corresponding strategies,provide training and guidance for online appointment nurses,develop relevant regulations,and improve the management mechanisms of the internet platform to ensure the safety of home based nasogastric intubation for online appointment nurses and improve the quality of the"Internet Plus Nursing Services."

Objective:To study the effects of remimazolam on stress response index, T lymphocyte subsets and postoperative delirium in patients undergoing modified radical mastectomy.Methods:A total of 120 patients with breast cancer who underwent modified radical mastectomy in our hospital from Aug. 2024 to Dec. 2024 were separated into the control group (n=60, anesthetic induction and maintenance with Propofol) and the observation group (n=60, anesthetic induction and maintenance with remimazolam) according to random number table method, and the other anesthetic drugs were the same. The operation time, anesthesia recovery time, postoperative delirium and cognitive dysfunction of the two groups were observed, and the changes of stress response indexes and T lymphocyte subsets indexes at different time points were compared, and the adverse reactions after anesthesia were counted.Results:The incidence of postoperative delirium and cognitive dysfunction in the observation group was lower than that in the control group ( x2=4.62, 5.18, P < 0.05), and there was no statistically significant difference in operation time or anesthesia recovery time between the two groups ( t=0.43, 1.71, P > 0.05). The observation group had lower serum cortisol (Cor), norepinephrine (NE) and epinephrine (E) levels 30 min after anesthesia induction (T 1) and immediately after surgery (T 2) ( t=5.53, 6.71, 9.33, 6.74, 7.26, 8.77, P < 0.05), while the comparison of those indexes before surgery (T 0) and 12 h after surgery (T 3) showed no statistically significant difference ( t=1.19, 1.85, 0.90, 1.55, 1.64, 1.81, P > 0.05). The levels of CD3 +T, CD4 +T and CD4 +/CD8 + in the observation group were higher than those in the control group at T 1, T 2 and T 3 ( t=2.21, 4.94, 4.77, 4.44, 6.24, 7.07, 2.11, 2.56, 2.15, P < 0.05), and there was no statistically significant difference in those indexes between the two groups at T 0 ( t=0.76, 0.79, 1.51, P > 0.05). The incidence of adverse reactions after anesthesia showed no statistically significant difference between the two groups [25.00% (15/60) and 33.33% (20/60) ] ( χ2=1.008, P > 0.05) . Conclusion:The induction and maintenance of remimazolam anesthesia can effectively reduce the incidence of postoperative delirium and cognitive dysfunction in patients with modified radical mastectomy, relieve the body stress response of patients, and effectively reduce the influence of anesthesia on T lymphocytes.

Objective To analyze the characteristics of blood transfusion consultation cases and establish the consulta-tion route,so as to provide reference for blood transfusion doctors to participate in blood transfusion consultation practice.Methods The cases involved in clinical transfusion consultation in the blood transfusion department of our hospital from 2020 to 2023 were collected from the hospital information system(HIS),and then classified by department and consultation type to summarize the main points of transfusion consultation,formulate transfusion consultation routes,and conduct typical cases analysis.Results There were 315 clinical transfusion consultations from 2020 to 2023,with an increasing trend year by year(26 in 2020,67 in 2021,81 in 2022,141 in 2023).The consultations involved 24 departments,including cardio-vascular medicine 14.0%(44/315),orthopedics 12.7%(40/315),intensive care medicine 8.9%(28/315),general medi-cine 8.3%(28/315),cardiopulmonary disease 6.0%(19/315),etc.There were 8 categories of consultations,including 35.6%(112/315)autologous ozonized blood transfusion,23.8%(75/315)plasma exchange,14.9%(47/315)perioperative mass blood preparation(transfusion),11.4%(36/315)platelet-rich plasma therapy and 6.3%(20/315)autologous blood collection,etc.The clinical blood transfusion consultation route was formulated according to the consultation points.Six pa-tients with various diseases were treated by blood transfusion department.With effective treatment measures taken,all of them improved and were discharged.Conclusion The summary of key points of clinical blood transfusion consultation and formulation of the blood transfusion consultation route by department of blood transfusion are conducive to the implementation of blood transfusion consultation and guarantee the safety of patients.

Objective Previous studies on the association between lipid profiles and chronic kidney disease(CKD)have yielded inconsistent results and no defined thresholds for blood lipids. Methods A prospective cohort study including 32,351 subjects who completed baseline and follow-up surveys over 5 years was conducted.Restricted cubic splines and Cox models were used to examine the association between the lipid profiles and CKD.A regression discontinuity design was used to determine the cutoff value of lipid profiles that was significantly associated with increased the risk of CKD. Results Over a median follow-up time of 2.2(0.5,4.2)years,648(2.00%)subjects developed CKD.The lipid profiles that were significantly and linearly related to CKD included total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),TC/HDL-C,and TG/HDL-C,whereas low-density lipoprotein cholesterol(LDL-C)and LDL-C/HDL-C were nonlinearly correlated with CKD.TC,TG,TC/HDL-C,and TG/HDL-C showed an upward jump at the cutoff value,increasing the risk of CKD by 0.90%,1.50%,2.30%,and 1.60%,respectively,whereas HDL-C showed a downward jump at the cutoff value,reducing this risk by 1.0%.Female and participants with dyslipidemia had a higher risk of CKD,while the cutoff values for the different characteristics of the population were different. Conclusion There was a significant association between lipid profiles and CKD in a prospective cohort from Northwest China,while TG,TC/HDL-C,and TG/HDL-C showed a stronger risk association.The specific cutoff values of lipid profiles may provide a clinical reference for screening or diagnosing CKD risk.

Objective:To observe the effect of ubiquilin 2 gene (UBQLN2) on the radiosensitivity of human esophageal squamous cell carcinoma cells (ESCC) of EC109 and KYSE30, and explore underlying molecular mechanism.Methods:siRNA and lentivirus transfection techniques were used to establish UBQLN2-knockdown and UBQLN2-overexpression cell lines. The cells were irradiated with a dose of 4 Gy X-rays. UPLC-Q-TOF-MS technique was used for metabolite difference analysis and KEGG pathway analysis. The results of metabonomics analyses were verified by qRT-PCR assay. The influence of UBQLN2 level on the radiosensitivity of ESCC was confirmed by CCK-8 cell proliferation assay and clone formation assay and further verified by treating the cells with metabolic enzyme inhibitors and exogenous metabolites.Results:Compared with irradiation alone, down-regulating UBQLN2 in EC109 and KYSE30 cell lines reduced the cell survival by 32.29% and 16.42% ( t=5.35, 4.88, P<0.05), and reduced the clone formation rate by 11.07% and 7.47% after 4 Gy irradiation, respectively ( t=4.18, 5.09, P<0.05). On the contrary, up-regulating UBQLN2 in EC109 and KYSE30 cell lines increased the survival rate by 14.07% and 10.64% ( t=5.88, 4.21, P<0.05), and increased the clone formation rate by 6.53% and 7.87% after 4 Gy irradiation, respectively ( t=8.60, 8.26, P<0.05). Metabonomics study showed that the purine metabolic pathway was significantly enriched after down-regulating UBQLN2 in EC109 cell. The qRT-PCR experiment showed a positive correlation between the expression level of UBQLN2 and the mRNA level of five purine metabolism enzymes. The viability of irradiated UBQLN2-overexpression cells decreased by 18.28% and 25.58%, respectively ( t=7.76, 10.95, P<0.05), and the clone formation rate decreased by 9.33% and 9.93%, respectively ( t=5.97, 8.02, P<0.05) after adding mycophenolic acid(MPA). However, the survival rate of cells increased by by 8.28% and 10.74% ( t=2.83, 6.20, P<0.05), and the clone formation rate increased by 7.33% and 5.80%, respectively ( t=7.16, 5.49, P<0.05), when exogenous supplementation of nucleotides (ATP + GTP) were added. Conclusion:The expression level of UBQLN2 was negatively related to the radiosensitivity of ESCC by up-regulating purine metabolism.
