ObjectiveTo investigate the mechanism of action of Jiedu Huayu granules in improving liver injury in mice with acute liver failure （ALF） by observing its effect on a mouse model of ALF after prophylactic administration， and to provide a basis for clinical medication. MethodsA total of 60 specific pathogen-free male C57BL/6J mice were divided into normal group， model group， Jiedu Huayu granules group （JDHY group）， and farnesoid X receptor （FXR） agonist （GW4064） group using a random number table， with 15 mice in each group. The model of ALF was induced by a single intraperitoneal injection of D-galactosamine combined with lipopolysaccharide. The mice in the JDHY group were given prophylactic administration of 0.3 g/mL drug solution of Jiedu Huayu granules by gavage for 3 days before modeling， those in the normal group and the model group were given 0.9% NaCl solution by gavage， and those in the GW4064 group were given intraperitoneal injection of GW4064 for 3 consecutive days before modeling. The mice were sacrificed after modeling， and serum and liver tissue samples were collected. A veterinary automatic biochemical analyzer was used to measure the serum levels of total bilirubin （TBil）， total bile acids （TBA）， gamma-glutamyl transferase （GGT）， alanine aminotransferase （ALT）， and aspartate aminotransferase （AST） in mice from each group； HE staining was used to observe liver pathological changes； RT-PCR was used to measure the mRNA expression levels of FXR， fibroblast growth factor 15 （FGF15）， fibroblast growth factor receptor 4 （FGFR4）， small heterodimer partner （SHP）， and bile salt export pump （BSEP） in mice， and Western blot was used to measure the protein expression levels of FXR， FGF15， FGFR4， SHP， and BSEP. A one-way analysis of variance was used for comparison between groups， and the Dunett method was used for further comparison between two groups. ResultsCompared with the normal group， the model group had significant increases in the serum levels of TBil， ALT， AST， TBA， and GGT （all P<0.01）， and compared with the model group， the JDHY group and the GW4064 group had significant reductions in the serum levels of TBil， ALT， AST， TBA， and GGT （all P <0.01）. HE staining showed that compared with the model group， the JDHY group and the GW4064 group had milder pathological injury， a reduction in the area of hepatocyte necrosis， and alleviation of cellular swelling and edema. Compared with the normal group， the model group had significant reductions in the mRNA and protein expression levels of FXR， FGF15， FGFR4， SHP， and BSEP in liver tissue （all P <0.01）， and compared with the model group， the JDHY group and the GW4064 group had significant increases in the mRNA and protein expression levels of FXR， FGF15， FGFR4， SHP， and BSEP in liver tissue （all P <0.05）. ConclusionJiedu Huayu granules may alleviate liver injury in mice with ALF through the FXR/SHP axis.

Hepatitis B virus （HBV） infection is the primary cause of viral hepatitis and represents a substantial disease burden in China. However， effective and safe agents capable of completely eliminating HBV DNA are still lacking. In modern medicine， anti-HBV strategies mainly target covalently closed circular DNA （cccDNA）， among other mechanisms， and multiple novel drugs are currently under clinical investigation. Traditional medicine has been shown to exert anti-HBV effects through direct pathways， such as blocking viral entry， as well as indirect pathways， including the regulation of programmed cell death. Studies have confirmed that the integration of traditional Chinese medicine （TCM） and Western medicine in treating HBV infection and its related complications offers complementary advantages， particularly in enhancing HBV clearance rates， improving liver function， preventing various complications， and delaying the progression from hepatic fibrosis to hepatocellular carcinoma. This review focuses on advances in anti-HBV research involving TCM， Western medicine， and their integrated application， aiming to provide a basis for integrated HBV therapy and new drug development.

Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Objective:To investigate the current state of death cognition among healthcare providers in hematology department and their attitudes toward hospice care for patients with hematologic malignancies.Methods:A cross-sectional investigation study was conducted. A total of 198 medical staff in hematology department of 4 teaching hospitals, including the First School of Clinical Medicine of Guangdong Medical University, Fujian Medical University Union Hospital, the Affiliated Hospital of Putian University and the First Affiliated Hospital of Gannan Medical University from March 2024 to June 2024 were selected as the investigation subjects. The general situation and background of medical staff in hematology department were investigated by using the "General Sociological Questionnaire". "Death Attitude Description Scale (Chinese version)" was used to investigate the status of death cognition among medical staff in hematology department. "Frommelt Attitudes Toward Care of the Dying Scale Form B (Chinese version)" was used to investigate the hospice care attitude of medical staff in hematology department. The survey results of doctors and nurses were compared.Results:There were 105 doctors and 93 nurses in hematology department included in this study. A total of 198 qualified "General Sociology Questionnaires" were collected. After excluding 6 unqualified questionnaires, 192 copies of "Death Attitude Description Scale (Chinese version)" and "Frommelt Attitudes Toward Care of the Dying Scale Form B (Chinese version)" were collected. There were statistically significant differences in gender, educational background, political status and experience of taking care of terminally ill patients between doctors and nurses (all P < 0.05). The scores of approaching acceptance, neutral acceptance, death escape, death fear and flight acceptance were (4.35±0.37), (4.03±0.51), (2.98±0.62), (2.54±0.29) and (2.19±0.42) points, respectively in the doctor group; the corresponding scores were (3.12±0.41), (3.89±0.46), (2.66±0.63), (2.81±0.57) and (2.37±0.65) points, respectively in the nurse group, and the differences between the 2 groups were statistically significant (all P < 0.05). The total score of hospice care attitude of doctors in hematology department was (108±15) points, and that of nurses was (116±13) points, and the difference was statistically significant ( t = -3.61, P < 0.001). The hospice care attitude of doctors and nurses towards patients with hematologic malignancies is generally between positive and neutral. The nurse group showed more recognition of the positive role of the patient's family members in the process of hospice care, and the doctor group showed more recognition of the promoting role of medical staff in hospice care. There were statistically significant differences in hospice care attitude scores of medical staff in hematology department to patients with different occupational background, gender, age, place of residence, family discussion about death, whether the only child, whether they had the experience of taking care of terminally ill patients, and whether they suffered from serious illness and religious belief (all P < 0.05). Conclusions:The death cognition of medical staff in hematology department is neutral, and they show a certain sense of hospice care.

Alzheimer's disease(AD)is a neurodegenerative disease with highly heterogeneous pathological and clinical manifesta-tions,and it is the most common cause of dementia.This heterogeneity poses challenges for diagnosis,treatment,and evaluating novel pharmacological efficacy.This review summarizes the latest progress in the major clinical subtypes of AD based on clinical manifesta-tions,genetic,and pathological features.Early-onset and late-onset AD clinical subtypes may share the same symptoms but differ in etiology,age of onset,mode of presentation,disease progression,and associated comorbidities.Typical and atypical AD differ signifi-cantly in clinical manifestations,pathological features,and diagnostic criteria.Research on AD subtypes based on imaging and omics data has also made considerable progress.This review also outlines the molecular pathological heterogeneity of AD.A deep understand-ing of these heterogeneities is crucial for diagnosis,the formulation of pharmacological treatment strategies,and clinical management.

Cancer-related cognitive impairment is a common and serious complication in children with leukemia,which affects the quality of long-term survival and has adverse impact on their schooling,life,and socialization.Through a literature review,this article summarizes the sentinel factors for cancer-related cognitive impairment,including insomnia,anxiety,depression,high-dose methotrex-ate exposure,decreased lysophosphatidylcholine levels and elevated sphingomyelin concentrations in cerebrospinal fluid,MTHFR1298 genotype,and increases in inflammatory factors(TNF-α,IL-6,and IL-8).The existing assessment tools for sentinel factors lack sensi-tivity and specificity,and subsequent large-sample multicenter studies should be conducted to validate the accuracy of the above indi-cators in predicting cancer-related cognitive impairment in children with leukemia,so as to achieve early intervention and improve the quality of long-term survival.

Osteoporotic vertebral compression fractures(OVCFs)are common orthopedic conditions that can lead to spinal pain and deformity,which greatly affects the quality of life of patients.Currently,there are various treatment methods for OVCFs,but there is still a lack of standards for optimal treatment modalities.Therefore,this article introduces the current treatment methods and character-istics of epidemiology for OVCFs,in order to improve the awareness of this disease among clinicians and provide a reference for select-ing more appropriate treatment regimens.Conservative treatment measures,such as bracing and analgesia,are the basic treatment mea-sures for OVCFs,and anti-osteoporosis drugs play a crucial role in management.Minimally invasive procedures,including percutane-ous vertebroplasty and percutaneous balloon kyphoplasty,remain the primary surgical interventions,and traditional open surgeries are also an important part of treatment,such as anterior spinal fusion,combined anterior and posterior spinal fusion,posterior spinal fusion with three-column osteotomy,and posterior spinal fusion with vertebroplasty.Furthermore,surgeons should focus on the accumulation of related surgical techniques and skills during surgery to effectively address the challenges and complications associated with surgical interventions.Finally,scientific and appropriate treatment methods should be selected for patients,in order to improve long-term treat-ment outcomes and increase the degree of satisfaction among pa-tients.

Objective:To explore the application value of a novel bag respirator assisted ventilation device in postoperative transport under general anesthesia with laryngeal mask.Methods:A total of 133 patients in postoperative transport who underwent elective bron-choscopy or treatment under general anesthesia with laryngeal mask in the First Affiliated Hospital of Chongqing Medical University,from June to August 2023 were selected.The patients were randomly divided into control group(n=65)and experimental group(n=68),and received manual bag respirator assisted ventilation and the novel bag respirator assisted ventilation device during their postop-erative transport,respectively.The pulse oxygen saturation(SpO2),heart rate(HR),and ventilation frequency during transport,trans-port duration,and transport-related adverse events were compared between the two groups.Results:The difference in SpO2 was signifi-cant when comparing the two groups(Fbetween groups=18.588,P<0.001),and the SpO2 of patients in the experimental group was signifi-cantly higher than that of patients in the control group during and after transport(P<0.001).The difference in HR was not significant when comparing the two groups(Fbetween groups=0.089,P=0.766),but it was significant between the control and experimental groups before and after transport(Ftime point=12.430,P<0.001);the HR in the con-trol and experimental groups before and during transport was signifi-cantly lower than that after transport(all P<0.001).The ventilation frequency of the experimental group was significantly lower than that of the control group(P<0.001).The transport duration in the ex-perimental group was longer than that in the control group,but the difference was not significant(P=0.987).Both groups successfully completed the trial without transport-related adverse events and achieved safe transport.Conclusion:Compared with the manual bag respirator assisted ventilation technology,the novel bag respirator assisted ventilation device for respiratory support during postopera-tive transport in patients under general anesthesia with laryngeal mask is more able to reduce the impact on the patient's hemodynam-ics and conducive to the maintenance of the patient's stable vital signs,showing a good clinical application value.It is expected to be a safe and effective ventilation method during intrahospital transport in some patients under general anesthesia.
