In cardiovascular disorders, neurological diseases, and chronic metabolic diseases, the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway is essential for maintaining cell homeostasis. According to studies, boosting Nrf2 expression can be used to cure or prevent chronic diseases that are characterized by oxidative stress, inflammation, and mitochondrial dysfunction. Nonalcoholic fatty liver disease (NAFLD) is a chronic metabolic liver disease characterized by hepatic steatosis brought on by a number of causes other than alcohol. In recent years, its incidence has gradually risen across the globe. According to relevant studies, NAFLD and the Nrf2 signaling pathway are tightly connected. Inhibiting lipid production and metabolism-related enzymes, repairing impaired liver metabolism, and lowering hepatic lipid storage are all possible with Nrf2 activation. Exercise is a powerful tool for treating and preventing NAFLD. However, exercise type, exercise intensity, environment, and exhaustion all have an impact on the Nrf2 signaling pathway. By activating Nrf2, exercise can lessen liver inflammation, oxidative stress, endoplasmic reticulum stress, and insulin resistance, and ameliorate liver damage to improve NAFLD. The activation of Nrf2 signaling pathway, its associated mechanism of controlling antioxidation, and the impact of exercise on the Nrf2 signaling pathway are all explained in this work. Based on the pathogenesis of NAFLD, this article examines the connection between exercise, Nrf2, and NAFLD, and the current state of knowledge regarding Nrf2’s role in the amelioration of NAFLD through exercise. It offers a theoretical frame of reference for future research into how Nrf2 might be used to improve NAFLD.

Objective This study aimed to evaluate whether the onset of the plateau phase of slow hepatitis B surface antigen decline in patients with chronic hepatitis B treated with intermittent interferon therapy is related to the frequency of dendritic cell subsets and expression of the costimulatory molecules CD40,CD80,CD83,and CD86. Method This was a cross-sectional study in which patients were divided into a natural history group(namely NH group),a long-term oral nucleoside analogs treatment group(namely NA group),and a plateau-arriving group(namely P group).The percentage of plasmacytoid dendritic cell and myeloid dendritic cell subsets in peripheral blood lymphocytes and monocytes and the mean fluorescence intensity of their surface costimulatory molecules were detected using a flow cytometer. Results In total,143 patients were enrolled(NH group,n = 49;NA group,n = 47;P group,n = 47).The results demonstrated that CD141/CD1c double negative myeloid dendritic cell(DNmDC)/lymphocytes and monocytes(%)in P group(0.041[0.024,0.069])was significantly lower than that in NH group(0.270[0.135,0.407])and NA group(0.273[0.150,0.443]),and CD86 mean fluorescence intensity of DNmDCs in P group(1832.0[1484.0,2793.0])was significantly lower than that in NH group(4316.0[2958.0,5169.0])and NA group(3299.0[2534.0,4371.0]),Adjusted P all<0.001. Conclusion Reduced DNmDCs and impaired maturation may be associated with the onset of the plateau phase during intermittent interferon therapy in patients with chronic hepatitis B.

Objective To explore characteristics of clinical parameters and cytokines in patients with drug-induced liver injury(DILI)caused by different drugs and their correlation with clinical indicators. Method The study was conducted on patients who were up to Review of Uncertainties in Confidence Assessment for Medical Tests(RUCAM)scoring criteria and clinically diagnosed with DILI.Based on Chinese herbal medicine,cardiovascular drugs,non-steroidal anti-inflammatory drugs(NSAIDs),anti-infective drugs,and other drugs,patients were divided into five groups.Cytokines were measured by Luminex technology.Baseline characteristics of clinical biochemical indicators and cytokines in DILI patients and their correlation were analyzed. Results 73 patients were enrolled.Age among five groups was statistically different(P=0.032).Alanine aminotransferase(ALT)(P=0.033)and aspartate aminotransferase(AST)(P=0.007)in NSAIDs group were higher than those in chinese herbal medicine group.Interleukin-6(IL-6)and tumor necrosis factor alpha(TNF-α)in patients with Chinese herbal medicine(IL-6:P<0.001;TNF-α:P<0.001)and cardiovascular medicine(IL-6:P=0.020;TNF-α:P=0.001)were lower than those in NSAIDs group.There was a positive correlation between ALT(r=0.697,P=0.025),AST(r=0.721,P=0.019),and IL-6 in NSAIDs group. Conclusion Older age may be more prone to DILI.Patients with NSAIDs have more severe liver damage in early stages of DILI,TNF-α and IL-6 may partake the inflammatory process of DILI.

Objective:To analyze the disease characteristics of aspiration pneumonia and its risk factors.Methods:In this retrospective case-control study, analysis was conducted on data from 92 patients aged &ge; 60 years admitted to Beijing Jishuitan Hospital, Capital Medical University between June 1, 2018 and July 31, 2022, with aspiration pneumonia(AsP) as the primary diagnosis at the time of hospital discharge and from non-AsP patients admitted during the same period.The number of participants was matched at a 1∶1 ratio.Results:The average age of the AsP group was(80.88 ± 9.41) years and 57(62.0%) were men.The average age of the control group was(77.74 ± 10.98) years and 52(56.5%) were men.There was no statistically significant difference in age and sex ratio(age: t=1.973, P=0.060; sex ratio: χ2=0.661, P=0.416).Univariate analysis showed that, at admission, body mass index(BMI) and activities of daily living(ADL) scores of the AsP group were lower than those of the non-AsP group, the proportions of patients with gastroesophageal reflux disease, acute trauma, cerebrovascular disease, history of cerebral infarction/hemorrhage and sequelae of cerebrovascular disease were higher than those of the non-AsP group(all P<0.05), and the proportions of patients receiving feeding via indwelling nasogastric intubation and tracheal intubation were also higher in the AsP group(all P<0.05).The white blood cell count, the percentage of neutrophils and the procalcitonin level in the first round of tests were higher in the AsP group than those in the non-AsP group and the maximum values of the above parameters during hospitalization were also higher than those in non-AsP patients, while the levels of albumin and prealbumin were lower than those in the non-AsP group( P<0.05 for all).Chest CT showed that 83.7%(77/92) of patients with AsP had bilateral pneumonia, higher than 55.4%(51/92) in the non-AsP group( χ2=8.569, P=0.014).Multivariate Logistic regression analysis showed that male sex( OR=16.206, 95% CI: 1.268-207.191, P=0.032) was a risk factor for AsP, and BMI( OR=0.747, 95% CI: 0.582-0.959, P=0.022) and ADL score at admission( OR=0.945, 95% CI: 0.903-0.988, P=0.014) were protective factors against AsP.ADL score at admission( OR=0.951, 95% CI: 0.907-0.982, P=0.043), tumor history( OR=6.859, 95% CI: 1.484-31.700, P=0.014), history of cerebral infarction/intracerebral hemorrhage( OR=4.368, 95% CI: 1.087-17.511, P=0.038), history of chronic renal insufficiency( OR=5.820, 95% CI: 1.445-23.440, P=0.013), acute respiratory failure( OR=5.281, 95% CI: 1.237-22.545, P=0.013) and myocardial infarction( OR=9.466, 95% CI: 2.151-41.660, P=0.003) were independent factors affecting the prognosis of pneumonia in the elderly. Conclusions:Aspiration pneumonia in the elderly is more common in men and in individuals with low BMI and low ADL scores.There is no increased risk of mortality in people with AsP, compared with people without AsP, but some risk factors in AsP patients may lead to poor prognosis, calling for increased awareness and early intervention in clinical practice.

Objective:To explore the effect of staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair.Methods:From January 2021 to December 2022, convenience sampling was used to select 73 patients who underwent arthroscopic rotator cuff repair in the Department of Hand Surgery at Affiliated Hospital of Nantong University as participants. According to the random number table method, patients were divided into a control group ( n=36) and an observation group ( n=37). Control group received routine rehabilitation nursing, while observation group received staged rehabilitation nursing. The University of California, Los Angeles (UCLA) Shoulder Rating Scale score, American Shoulder and Elbow Surgeons (ASES) Rating Scale score, Constant-Murley Shoulder Scale score, and complications during rehabilitation were compared between two groups of patients before and six months after intervention.

Six months after surgery, the Constant-Murley Shoulder Scale scores for daily life and shoulder range of motion in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05). During the rehabilitation period, the incidence of complications in observation group was lower than that in control group with a statistical difference ( P<0.05) . Conclusions:Staged rehabilitation nursing in patients undergoing arthroscopic rotator cuff repair shows significant effects and can effectively promote patient recovery.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

ObjectiveTo construct a neural network-like tissue with the potential of synaptic formation in vitro by seeding human induced pluripotent stem cell-derived neural precursor cells （hiPSC-NPCs） on decellularized optic nerve （DON）， so as to provide a promising approach for repair of nerve tissue injury. MethodsThrough directional induction and tissue engineering technology， human induced pluripotent stem cells （hiPSCs） and 3D DON scaffolds were combined to construct neural network-like tissues. Then the hiPSCs were directionally induced into human neural precursor cells （hNPCs） and neurons. Immunofluorescence staining was used to identify cell differentiation efficiency. 3D DON scaffolds were prepared. Morphology and cytocompatibility of scaffolds were identified by scanning electron microscopy and Tunnel staining. Induced hiPSC-NPCs were seeded on DON scaffolds. Immunofluorescence staining， scanning electron microscopy， transmission electron microscopy and patch clamp were used to observe the morphology and functional identification of constructed neural network tissues. Results①The results of immunofluorescence staining suggested that most of hiPSC-NPCs differentiated into neurons in vitro. We had successfully constructed a neural network dominated by neurons. ② The results of scanning electron microscopy and immunohistochemistry suggested that a neural network-like tissue with predominating excitatory neurons in vitro was successfully constructed. ③The results of immunohistochemical staining， transmission electron microscopy and patch clamp indicated that the neural network-like tissue had synaptic transmission function. ConclusionA neural network-like tissue mainly composed of excitatory neurons has been constructed by the combination of natural uniform-channel DON scaffold and hiPSC-NPCs， which has the function of synaptic transmission. This neural network plays a significant role in stem cell derived replacement therapy， and offers a promising prospect for repair of spinal cord injury （SCI） and other neural tissue injuries.

OBJECTIVE: To explore the effect of cytokine levels on early death and coagulation function of patients with newly diagnosed acute promyelocytic leukemia (APL). METHODS: Routine examination was performed on 69 newly diagnosed APL patients at admission. Meanwhile, 4 ml fasting venous blood was extracted from the patients. And then the supernatant was taken after centrifugation. The concentrations of cytokines, lactate dehydrogenase (LDH) and ferritin were detected by using the corresponding kits. RESULTS: It was confirmed that cerebral hemorrhage was a major cause of early death in APL patients. Elevated LDH, decreased platelets (PLT) count and prolonged prothrombin time (PT) were high risk factors for early death (P <0.05). The increases of IL-5, IL-6, IL-10, IL-12p70 and IL-17A were closely related to the early death of newly diagnosed APL patients, and the increases of IL-5 and IL-17A also induced coagulation disorder in APL patients by prolonging PT (P <0.05). In newly diagnosed APL patients, ferritin and LDH showed a positive effect on the expression of IL-5, IL-10 and IL-17A, especially ferritin had a highly positive correlation with IL-5 (r =0.867) and IL-17A (r =0.841). Moreover, there was a certain correlation between these five high-risk cytokines, among which IL-5 and IL-17A (r =0.827), IL-6 and IL-10 (r =0.823) were highly positively correlated. CONCLUSION Elevated cytokine levels in newly diagnosed APL patients increase the risk of early bleeding and death. In addition to the interaction between cytokines themselves, ferritin and LDH positively affect the expression of cytokines, thus affecting the prognosis of APL patients.
