This article presents a case study of a patient who visited the Geriatric Department of Peking Union Medical College Hospital due to "palpitations, shortness of breath for more than 2 years, limb weakness for 6 months, edema, and nocturnal dyspnea for 2 months". The patient exhibited decreased muscle strength in the limbs and involvement of swallowing and respiratory muscles, alongside complications of heart failure and various arrhythmias which were predominantly atrial. Laboratory tests revealed the presence of multiple autoantibodies and notably anti-mitochondrial antibodies. Following a comprehensive multidisciplinary evaluation, the patient was diagnosed with anti-mitochondrial antibody-associated inflammatory myopathy. Treatment involved a combination of glucocorticoids and immunosuppressants, along with resistance exercises for muscle strength and rehabilitation training for lung function, resulting in significant improvement of clinical symptoms. The case underscores the importance of collaborative multidisciplinary approaches in diagnosing and treating rare diseases in elderly patients, where careful consideration of clinical manifestations and subtle abnormal clinical data can lead to effective interventions.

ObjectiveTo unveil the mechanism of Jianpi Huogu prescription (JPHGP) in ameliorating the dyslipidemia of steroid-induced osteonecrosis of the femur head (SONFH) by oxylipidomics combined with transcriptomics. MethodsSixty SD rats were assigned into normal, model, low-, medium-, and high-dose (2.5, 5, 10 g·kg-1, respectively) JPHGP, and Jiangushengwan (1.53 g·kg-1) groups. Lipopolysaccharide was injected into the tail vein at a dose of 20 μg·kg-1 on days 1 and 2, and methylprednisolone sodium succinate was injected at a dose of 40 mg·kg-1 into the buttock muscle on days 3 to 5. The normal group received an equal volume of normal saline. Drug administration by gavage began 4 weeks after the last injection, and samples were taken after administration for 8 weeks. Hematoxylin-eosin staining was conducted to reveal the histopathological changes of the femoral head, and the number of adipocytes, the rate of empty bone lacunae, and the trabecular area were calculated. Micro-computed tomography was used for revealing the histological and histomorphometrical changes of the femoral head. Enzyme-linked immunosorbent assay was employed to measure the serum levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB). At the same time, the femoral head was collected for oxylipidomic and transcriptomic detection. The differential metabolites and differential genes were enriched and analyzed, and the target genes regulating lipid metabolism were predicted. The predicted target proteins were further verified by molecular docking, immunohistochemistry, and Western blot. ResultsCompared with the normal group, the model group showcased thinning of the femoral head, trabecular fracture, karyopyknosis, subchondral cystic degeneration, increases in the number of adipocytes and the rate of empty bone lacunae (P<0.01), a reduction in the trabecular area (P<0.01), decreases in BMD, Tb.Th, Tb.N, and BV/TV, and increases in Tb.Sp and BS/BV (P<0.01). Compared with the model group, the JPHGP groups showed no obvious thinning of the femoral head or subchondroidal cystic degeneration. The high- and medium-dose JPHGP groups presented declines in the number of adipocytes and the rate of empty bone lacunae, an increase in the trabecular area (P<0.05, P<0.01), rises in BMD, Tb.Th, Tb.N, and BV/TV, and decreases in Tb.Sp and BS/BV (P<0.05, P<0.01). Compared with the normal group, the model group showcased raised serum levels of TG, TC, LDL, and ApoB and lowered serum levels of HDL and ApoA1 (P<0.01). Compared with the model group, the JPHGP groups had lowered serum levels of TG, TC, LDL, and ApoB (P<0.05, P<0.01) and a risen serum level of ApoA1 (P<0.05, P<0.01). Moreover, the serum level of HDL in the high-dose JPHGP group increased (P<0.01). A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head, and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation, lipids, apoptosis, and osteoclast differentiation. Molecular docking, immunohistochemistry, and Western blot results showed that compared with the normal group, the model group displayed increased content of 5-lipoxygenase (5-LO) and peroxisome proliferator-activated receptor γ (PPARγ) in the femoral head (P<0.01). Compared with the model group, medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ (P<0.05, P<0.01). ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.

Objective To investigate the incidence, severity and longitudinal trajectories of symptoms at various time points in the perioperative period of lung cancer patients, and to provide scientific basis for clinical staff to implement predictive nursing and dynamic management of symptom clusters. Methods A prospective longitudinal investigation was conducted. The patients with lung cancer who underwent thoracoscopic lung surgery in four wards of the Department of Thoracic Surgery in our hospital were investigated by face-to-face and telephone follow-up before surgery, 1-2 days after surgery, on the day of discharge and 2 weeks after discharge. The investigation tool was the revised Chinese version of MD Anderson Symptom Inventory lung cancer specific module. Results A total of 192 patients with lung cancer were included in this study, including 59 males and 133 females, with an average age of (55.68±11.01) years. There were two symptom clusters (respiratory-gastrointestinal and emotional/psychological-disturbed sleep symptom clusters) before surgery, three symptom clusters (respiratory, gastrointestinal, and emotional/psychological-disturbed sleep symptom clusters) 1-2 days after surgery, three symptom clusters (pain-fatigue-emotional/psychological, respiratory, and gastrointestinal symptom clusters) on the day of discharge, and two symptom clusters (pain-fatigue-respiratory and respiratory symptom clusters) 2 weeks after discharge. The composition of symptoms was different in each time point during perioperative period. Conclusion There are four symptom clusters in patients with lung cancer during perioperative period, which are pain-fatigue-disturbed sleep symptoms, gastrointestinal symptoms, respiratory symptoms and emotional/psychological symptoms. The symptom clusters of lung cancer patients at different time points are relatively stable, but the symptoms within the symptom clusters show dynamic changes. Medical staff should attach great importance to and continuously monitor the dynamic changes of perioperative symptom groups of lung cancer patients, do relevant education and nursing in advance, and timely adjust the management plan according to the symptom group evaluation results.

OBJECTIVE To optimize the prescription pre-review system in our hospital and evaluate its application effects. METHODS Aiming at the problems of imperfect rule base and high false positive rate in the early operation of the system, optimization measures were taken, including improving the content of the rule base, adjusting the interception level and prompt mode, refining the working model of prescription review pharmacists, and strengthening clinical communication. A retrospective cohort study was conducted, with prescription data from June to December 2023 (before optimization) as the control group and June to December 2024 (after optimization) as the observation group. Through inter group comparative analysis, the actual effect of optimizing the prescription pre-approval system was evaluated. RESULTS The prescription qualified rate increased from (82.51± 4.04)% before optimization to (90.98±1.55)% after optimization; the false positive rate decreased from (20.87±1.64)% before optimization to (7.41±2.04)% after optimization. The monthly range of prescription qualified rate narrowed from 10.24% to 4.11%, and the coefficient of variation decreased from 4.92% to 1.73%. The monthly range of false positive rate slightly increased from 4.40% to 5.34%, the coefficient of variation rose from 8.32% to 26.18%. CONCLUSIONS Through multi-dimensional optimizations of the prescription pre-review system in our hospital, its prescription review efficiency has been significantly enhanced, the quality of prescriptions has steadily improved, and the accuracy of reviews has notably improved.

ObjectiveTo systematically and objectively characterize the pharmacological effects of Fufang Biejia Ruangan pills (FBRP) in the intervention of alcoholic liver disease (ALD) using acute and chronic ALD mouse models and to elucidate its molecular mechanisms. MethodFifty SPF-grade male BALB/c mice were randomly divided into the normal group, model group, and FBRP low-, medium-, and high-dose groups (9.6, 19.2, 38.4 mg·kg-1). Except for the normal group, the remaining groups were given 56° white wine by gavage to establish the acute ALD model, with samples collected after 4 weeks. Thirty SPF-grade male C57BL/6N mice were randomly divided into the normal group, model group, and FBRP medium-dose group (19.2 mg·kg-1). The chronic ALD mouse model was established using the Lieber-DeCarli method over a 10-week period. Inflammatory markers in liver tissues were assessed using hematoxylin-eosin (HE), Sirius Red, oil red O staining, and enzyme-linked immunosorbent assay (ELISA). Intoxication behaviors of each group were objectively evaluated through sobering-up time, net-catching, and pole-climbing tests. Further bioinformatics analyses based on clinical transcriptomic data were conducted to identify key targets and molecular mechanisms of FBRP in alleviating ALD through liver-brain dialogue, with experimental validation by ELISA, Western blot, and immunohistochemical staining. ResultCompared with the normal group, the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in liver tissues of mice in the acute and chronic ALD model groups were significantly increased (P<0.05). Compared with the model group, the levels of AST and ALT in liver tissue of mice in FBRP groups were significantly decreased (P<0.05). Compared with the normal group, the time of grasping the net and climbing the pole in the acute ALD model group was significantly decreased within 4 weeks (P<0.01). Compared with the model group, the grasping and climbing time of FBRP high dose groups increased significantly within 4 weeks (P<0.05). Compared with the normal group, the expression of high mobility group protein B1 (HMGB1) protein in liver tissue and prefrontal lobe tissue of mice in the chronic ALD model group was significantly increased (P<0.01). Compared with the model group, the expression of HMGB1 protein in FBRP medium dose group was significantly decreased (P<0.05,P<0.01). Compared with the normal group, the expression of brain-derived neurotrophic factor (BDNF) protein and the release of γ-aminobutyric acid (GABA) in the prefrontal cortex of the model group were significantly decreased (P<0.01). Compared with the model group, the expression of BDNF protein and the release of GABA in the FBRP medium dose group were significantly increased (P<0.05). ConclusionThis study revealed that FBRP improved key pathological changes in ALD by modulating liver-brain dialogue mediated by the HMGB1-BDNF axis. These findings provide experimental evidence for the clinical use of FBRP in treating ALD and offer new insights for the development of ALD therapeutic agents.

Objective To investigate the current status of control preference in the surgery of lung cancer patients and explore its correlation with perceived social support. Methods General information questionnaire, control preference scale, and perceived social support scale were used to investigate the lung cancer patients who underwent surgery in Beijing Cancer Hospital from February to May 2022. Results A total of 360 survey questionnaires were distributed, and 344 valid questionnaires were collected, with an effective rate of 95.6%. The expected participation style of patients was passive in 145 patients (42.2%), while the actual participation style was more inclined to be active in 154 (44.8%) patients. The compliance rate of patients’ expected and actual participation styles in the treatment control preference process was 61.9% (Kappa=0.437, P<0.001). The results of the analysis of influencing factors showed that the level of cultural education was an influencing factor in the actual participation of lung cancer patients in surgery control preference (P=0.029). The results of Spearman's correlation analysis showed that the actual participation of lung cancer patients in surgery control preference was positively associated with perceived social support (r=0.159, P<0.01), and its dimensions including family support (r=0.152, P<0.01), friend support (r=0.133, P<0.05), and other social support (r=0.142, P<0.01). Conclusion Patients’ expected control preference style is generally consistent with their actual control preference style, which is influenced by their cultural education and positively correlated with perceived social support. Medical and nursing staff should pay attention to the participation style of patients taking surgery decisions, develop decision aids according to different education levels, and develop individualized interventions from the perspective of improving social support initially, to improve patients’ treatment compliance and treatment care satisfaction.
