Objective:To understand the latent categories of apathy in young and middle-aged patients with hemorrhagic stroke and analyze the relationship between these categories and disability acceptance, providing a theoretical basis for targeted interventions.Methods:A convenience sampling method was used to select young and middle-aged patients with hemorrhagic stroke hospitalized at Huai′an First Hospital Affiliated to Nanjing Medical University between September 2020 and September 2023. A general information questionnaire, the Apathy Evaluation Scale-Clinician Administered, and the Acceptance of Disability Scale Revised were used for a cross-sectional survey. Latent profile analysis was conducted using Mplus 8.7 software to categorize apathy in these patients, and differences in disability acceptance among the categories were compared.Results:A total of 210 questionnaires were distributed and 203 valid questionnaires were collected. Among 203 patients were included, with 112 males and 91 females, aged 30-59 (47.60 ± 8.51) years old. The apathy score was (46.66 ± 8.78) points, and three latent categories were identified: "high active ability-low apathy" (26.1%, 53/203), "high social ability-moderate apathy" (28.6%, 58/203), and "generally high apathy" (45.3%, 92/203). The total disability acceptance scores for the three categories were (78.19 ± 13.30), (69.50 ± 11.01), and (60.86 ± 14.00) points, respectively, with statistically significant differences ( F=30.39, P<0.01). Conclusions:Apathy in young and middle-aged patients with hemorrhagic stroke can be categorized into three latent profiles, with differences in disability acceptance among the categories. Targeted management and interventions should be developed based on these homogeneous groups to improve disability acceptance.

OBJECTIVE To evaluate the status of microbial contamination in the environment of respiratory tract specimens sampling rooms and observe the association of the factors such as design and layouts of the sampling rooms with the potential risk of infections in the environment so as to provide scientific bases for optimizing the construction standards of fever clinics of the medical institutions.METHODS The sampling rooms of fever clinic were chosen from 10 tertiary or above medical institutions of Hangzhou,and the samples were collected from the key sites such as air,object surfaces and hands of health care workers.The respiratory tract pathogens in the sam-ples were detected by FilmArray full-automatic medical PCR analysis system,and the pathogens in the samples were detected by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry(MALDI-TOF MS).The data including the areas,windows,mechanical ventilation facilities,physical partitions,frequencies and modes of disinfection and daily amounts of diagnosis and treatment of the 10 sampling rooms were investigated,and the univariate analysis was performed for their association with the microbial contamination of environment.RESULTS The isolation rate of respiratory tract pathogens was 10.00％(4/40),respiratory syn-cytial virus,human rhinovirus and adenovirus were dominant among the respiratory tract pathogens.The isolation rate of bacteria was 71.88％(23/32),Staphylococcus ho minis and Staphylococcus epidermidis were the major species of opportunistic pathogens isolated.The result of univariate analysis indicated that both the presence of windows(P=0.012)and mechanical ventilation facilities(P=0.047)were associated with the potential risk of infections in the environment(P＜0.05);while the factors such as the areas of sampling rooms,physical parti-tions,disinfection modes and daily amounts of diagnosis and treatment were not remarkably associated with the potential risk of infections in the environment.CONCLUSION It is an effective way to physically separate the air-flow from other areas or fix the mechanical ventilation facilities to create proper airflow during the construction of fever clinic sampling rooms so as to reduce the potential risk of infections in the environment of sampling rooms.

Objective To investigate the mechanism by which ginkgetin attenuates H9c2 cells injury.Methods H9c2 cells were divided into five groups:control,lipopolysaccharide(LPS),LPS+3-methyladenine(3-MA,an autophagy inhibitor),LPS+ginkgetin,and LPS+3-MA+ginkgetin.Cell viability and cytotoxicity were assessed using the cell CCK-8 and lactate dehydrogenase assays,respectively.Immunofluorescence staining for LC3,monodansylcadaverine staining for autophagosomes,and flow cytometry were used to measure apop-tosis rates.Quantitative real-time PCR was performed to measure the expression of NR4A2/p53/Bax pathway.Western blotting was used to detect the expression of NR4A2,p53,Bax,LC3,Beclin-1,p62,cleaved caspase-3,and Bcl-2 proteins.Results Compared to the LPS group,ginkgetin significantly increased LC3 fluorescence levels and monodansylcadaverine fluorescence intensity,decreased apoptosis,upregulated NR4A2,downregulated p53 and Bax,increased LC3,Beclin-1,and Bcl-2 proteins,and decreased p62 and cleaved caspase-3(P＜0.05).The autophagic inhibitor,3-MA,confirmed that ginkgetin protected H9c2 cells from LPS-induced apoptosis via autophagy regulation.Conclusion Ginkgetin mitigated cardiomyocyte injury by enhancing autophagic flux and alleviating LPS-induced H9c2 cells apoptosis by modulating the NR4A2/p53/Bax pathway.

Houpo Sanwutang， included in the Catalogue of Ancient Classical Prescriptions （Second Batch）， was first recorded in the Synopsis of Golden Chamber written by ZHANG Zhongjing from the Eastern Han dynasty and was modified by successive generations of medical experts. A total of 37 pieces of effective data involving 37 ancient Chinese medical books were retrieved from different databases. Through literature mining， statistical analysis， and data processing， combined with modern articles， this study employed bibliometrics to investigate the historical origin， composition， decoction methods， clinical application， and other key information. The results showed that the medicinal origin of Houpo Sanwutang was clearly documented in classic books. Based on the conversion of the measurements from the Han Dynasty， it is recommended that 110.4 g Magnolia Officinalis Cortex， 55.2 g Rhei Radix et Rhizoma， and 72 g Aurantii Fructus Immaturus should be taken. Magnolia Officinalis Cortex and Aurantii Fructus Immaturus should be decocted with 2 400 mL water first， and 1 000 mL should be taken from the decocted liquid. Following this， Rhei Radix et Rhizoma should be added for further decoction， and then 600 mL should be taken from the decocted liquid. A single dose of administration is 200 mL， and the medication can be stopped when patients restore smooth bowel movement. Houpo Sanwutang has the effect of moving Qi， relieving stuffiness and fullness， removing food stagnation， and regulating bowels. It can be used in treating abdominal distending pain， guarding， constipation， and other diseases with the pathogenesis of stagnated heat and stagnated Qi in the stomach. The above results provide reference for the future development and research of Houpo Sanwutang.

Objective:To explore the association between triglyceride-glucose (TyG) index and carotid artery plaque in patients with type 2 diabetic kidney disease (DKD).Methods:Clinical data of 620 DKD patients admitted in the Department of Endocrinology, the Affiliated Huai′an First People′s Hospital of Nanjing Medical University from August 2018 to August 2022 were retrospectively analyzed, including 366 cases with carotid artery plaque and 254 cases without carotid plaque. According to TyG index quartile patients were divided into Q 1,Q 2, Q 3 and Q 4 groups with TyG index<8.94,≥8.94 and<9.44,≥9.44 and<9.96, and≥9.96, respectively. The prevalence of carotid plaque in DKD patients with different TyG index levels was analyzed. The relationship between TyG index and carotid plaque occurrence in DKD patients were analyzed with Logistic regression analysis and restricted cubic lines (RCS). Results:The age, course of disease, smoking rate, SBP, HbA1c, TG, BUN, eGFR and TyG indexes in carotid plaque group were significantly higher than those in non-carotid plaque group (all P<0.05). Binary logistic regression analysis showed that age, disease course, smoking rate, SBP, HbA1c, TG, BUN, low eGFR and TyG index were independent influencing factors for carotid plaque ( OR=1.05, 1.05, 1.88, 1.01, 1.09, 1.11, 1.09, 0.99 and 1.28, all P<0.05). The risk of carotid plaque in DKD patients in Q 3 and Q 4 groups was 2.20 and 2.50 times higher than that in Q 1 group. After adjusting for age, sex, course of disease, smoking, BMI, blood pressure (SBP and DBP), blood lipids (TC, HDL and LDL) and renal function, the risk of carotid plaque in DKD patients in Q 3 and Q 4 groups was higher than that in Q 1 group ( OR=1.95 and 2.24). RCS analysis showed that the correlation between TyG index and the risk of carotid plaque in DKD patients was linear(χ 2=0.40, P=0.527), and DKD patients with TyG index>9.95 had a higher risk of carotid plaque. Conclusions:TyG index is significantly elevated in DKD patients with carotid plaque, and TyG index is an independent risk factor for the occurrence of carotid plaques in DKD patients.
