ObjectiveTo explore the effect of modified Ditan Decoction (涤痰汤) on chronic intermittent hypoxia cognitive function and the potential function mechanism. MethodsTwenty-four Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, and a modified Ditan Decoction group, with eight rats in each group. Rats in the modified Ditan Decoction group were administered the decoction by gavage at 14.8 ml/(kg·d), while the normal group and the model group received the same dose of normal saline. Thirty minutes after daily gavage, the rats in all three groups were placed in an intermittent hypoxia chamber. The oxygen concentration for the model group and the modified Ditan Decoction group was adjusted daily for 8 hours using a computer program to establish the model, while the normal group was exposed to the same airflow rate of ambient air. The intervention was continued for 12 weeks to establish a chronic intermittent hypoxia rat model. The Y-maze test was used to evaluate spatial working memory in the rats. Resting-state functional magnetic resonance imaging (rs-fMRI) was performed to detect whole-brain regional homogeneity (ReHo) and seed-based functional connectivity (FC). Brain regions showing significant differences in rs-fMRI were selected for further analysis. Immunofluorescence was used to detect β-amyloid (Aβ) deposition and the number of ionized calcium-binding adapter molecule 1 (IBA1)-positive microglial cells. Immunohistochemistry was employed to assess the expression of synaptophysin (SYP), the excitatory synapse marker vesicular glutamate transporter 1 (Vglut1), and the inhibitory synapse marker vesicular γ-aminobutyric acid transporter (VGAT). ResultsCompared with the normal group, the model group showed a reduced spontaneous alternation rate in the Y-maze test. The smoothed Z-score standardized regional homogeneity (SzReHo) value in the left entorhinal cortex significantly increased, and the FC value from this seed point to the left basal forebrain significantly reduced. Additionally, the model group exhibited significantly higher Aβ fluorescence intensity and Iba1 positivity in the left entorhinal cortex, decreased expression of SYP, Vglut1, and VGAT, along with an increased Vglut1/VGAT ratio (P<0.05 or P<0.01). Compared to the model group, the modified Ditan Decoction group demonstrated an increased spontaneous alternation rate, a significantly reduced SzReHo value in the left entorhinal cortex, and a significantly increased FC value from this region to the left basal forebrain. Furthermore, this group showed significantly lower Aβ fluorescence intensity and Iba1 positivity in the left entorhinal cortex, increased levels of SYP, Vglut1, and VGAT, and a decreased Vglut1/VGAT ratio (P<0.05 or P<0.01). ConclusionModified Ditan Decoction can reconstruct the projection from the left basal forebrain to the entorhinal cortex in chronic intermittent hypoxia, thereby reducing Aβ aggregation and excessive microglial activation in the left entorhinal cortex. This process improves the excitation/inhibition imbalance caused by synaptic remodeling, ultimately enhancing cognitive function in rats of chronic intermittent hypoxia.

Objective To analyze the clinical significance of subjective visual vertical (SVV) tests at different head deflection angles in assessing utricle function in patients with benign paroxysmal positional vertigo (BPPV). Methods A total of 61 BPPV patients who were treated at the Hearing Impairment and Vertigo Diagnosis and Treatment Center of Otolaryngology Head and Neck Surgery, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from August 2022 to May 2023 were retrospectively included, and 29 healthy adults were selected as controls. SVV tests were performed on all research subjects at different head deflection angles: upright head (0°), left head 45° (L45°), right head 45° (R45°). The test results between the two groups were compared. Results SVV absolute value at R45° in BPPV group was lower than that in the control group (P=0.003); there was no significant difference in SVV values at 0° and L45° between the two groups. There was no statistical difference in SVV values at different head deflection angles between the control group and the left BPPV group. SVV absolute value at R45° in right BPPV group was lower than that in the control group (P<0.001); there was no statistical difference in SVV values at 0° and L45° between the two groups. Conclusions SVV test can provide subjective information about the utricle, and SVV tests at different head deflection angles can fine-tune evaluate the function of the utricle in BPPV patients.

OBJECTIVE To investigate the current status of pharmaceutical care in medical institutions in China, and provide experience and suggestions for better development of pharmaceutical care. METHODS Questionnaire survey was used to investigate the development of pharmaceutical care in medical institutions in 31 provinces (autonomous regions and municipalities directly) in March 2023, and descriptive analysis and binary logistic regression analysis on the influencing factors of pharmaceutical care were conducted. RESULTS A total of 1 368 questionnaires were sent out, and 1 304 valid questionnaires were collected with the effective recovery rate of 95.32%. Pharmaceutical care was carried out in 671 medical institutions (51.46%), and the rates of pharmaceutical care in tertiary, secondary, primary and other medical institutions were 74.79%, 27.97% and 7.35%, respectively. The average number of patients receiving pharmaceutical care was 2 638.96 per year, and there were 8.33 pharmacists in each medical institution to carry out pharmaceutical care, among which 93.68% were clinical pharmacists. The main departments covered by pharmaceutical care services included respiratory and critical care medicine, cardiology, intensive care unit, endocrinology, oncology, gastroenterology, obstetrics and gynecology and other departments. There were only 48 medical institutions (7.15%) with additional compensation for pharmaceutical care services. The main experiences of developing pharmaceutical care were to pay attention to talent cultivation and discipline construction, but the main difficulties were serious shortage of staff and qualified talents, low compensation level and low enthusiasm. Grade of medical institutions, the number of pharmacists engaged in clinical pharmacy, the number of qualified clinical pharmacists and the degree of information in the pharmacy department were the main influencing factors for carrying out pharmaceutical care (P<0.05). CONCLUSIONS In recent years, pharmaceutical care in Chinese medical institutions has made certain progress, while that of primary medical institutions, secondary medical institutions and other medical institutions should be improved. In the future, it is still necessary to further enhance the implementation of pharmaceutical care, promote personnel training, and attach importance to demonstrating the value of pharmaceutical care, thereby promoting the sustainable and high- quality development of pharmaceutical care.

ObjectiveChinese patent medicines for cardiovascular and cerebrovascular diseases are diverse and complex in their efficacy. The traditional classification method based on efficacy categories has certain limitations and cannot meet the clinical needs for individualized drug selection and variety comparison. This article, based on the formulation compatibility analysis technology of "Tangye Jingfa Tu", clarifies the composition and efficacy characteristics of common Chinese patent medicines used for cardiovascular and cerebrovascular diseases, providing support for the precise selection of these medicines. MethodsFifty-six representative Chinese patent medicines, covering all the efficacy subcategories of "stasis-resolving agents" in the National Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance Drug Catalogue (2023) (more than 50% of the total), were selected for the study. Within the knowledge system of "Tangye Jingfa Tu", the compatibility structure of herbal flavors and the proportion structure of herbal quantities for each Chinese patent medicine were determined. The correlation between these structures and the efficacy categories was analyzed to identify the similarities and differences among the selected Chinese patent medicines. Additionally, the efficacy was reclassified and compared according to the theoretical framework of tonifying and purging methods of five Zang organs in the "Tangye Jingfa Tu". ResultsThe representative Chinese patent medicines included in the analysis were Shexiang Baoxin pills, Danshen tablets, Qili Qiangxin capsules, Breviscapine tablets, etc., covering all the efficacy subcategories of "stasis-resolving agents". Among the 56 representative Chinese patent medicines, salty flavor was the most common (48), followed by pungent (33), and sweet (26). According to the dominant herbal flavor, salty flavor was the most common (37), followed by pungent (9), and sour (5). According to the dominant herbal quantity, salty flavor was the most common (27), followed by sour (7), and pungent (5). Furthermore, Chinese patent medicines with different efficacy subtypes showed different flavor characteristics. For example, most Qi-invigorating and blood-activating agents contained sweet drugs for tonifying the spleen (9/10), most Qi-moving and blood-activating agents contained pungent drugs for tonifying the liver (7/8), and all kidney-invigorating and blood-activating agents contained bitter drugs for tonifying the kidneys (6/6). However, the efficacy classification of individual medicines did not always align with the compatibility characteristics of their formulas, as seen with Dengyin Naotong capsules. ConclusionThe formulations of Chinese patent medicines for cardiovascular and cerebrovascular diseases predominantly feature salty, sour, and pungent flavors, which largely conform to the therapeutic principles of "nourishing the heart with salt and soothing the heart with sour" and the liver-heart, heart-spleen mother-child treatment relationship shown in the "Tangye Jingfa Tu". Using the "Tangye Jingfa Tu" framework to conduct research on the structure and efficacy characteristics of Chinese patent medicines is objective and effective.

ObjectiveTo analyze the etiological characteristics of two strains of Escherichia albertii first identified in Baoshan District, Shanghai, in 2024, to explore their antibiotic resistance characteristics, virulence characteristics, and multilocus sequence typing (MLST) to elucidate their genetic evolutionary relationships, so as to provide a scientific basis for the surveillance and control of Escherichia albertii in the local area. MethodsA total of 457 anal swabs were collected from patients with diarrhea in 2024, from which two suspected Escherichia albertii strains were isolated. The isolated strains were identified through mass spectrograph analysis, biochemical identification, and polymerase chain reaction (PCR) test. Microdilution broth method was used for the antimicrobial susceptibility testing, and whole-genome sequencing was performed for molecular characteristic analysis. ResultsMass spectrograph analysis and PCR test initially identified the two strains as Escherichia coli (E. coli), but their biochemical profiles were inconsistent with those of E. coli. Genomic sequencing identified the strains as Escherichia albertii, and which were named as S1 and S2, respectively. The antimicrobial susceptibility test showed that both strains were susceptible to β‑lactam antibiotics and moderately susceptible to polypeptide antibiotics. S1 was resistant to chloramphenicol (CHL), streptomycin (STR), tetracyclin (TET), florfenicol (FFC) and nalidixic acid (NAL), and carried five resistance genes including APH(6),APH(3), gyrA, tet and flor, whereas S2 was susceptible to the five antibiotics mentioned above. Neither of the two strains contained the stx virulence gene, but S2 harbored the astA virulence gene. The two Escherichia albertii strains had the MLST types of ST4638 and ST4606, respectively. The genome size of the two strains was 4.5 Mb, and the closest relative strain was GTC14781 (Escherichia albertii). The average nucleotide identity (ANI) values to the reference genome of E. coli were both below 90%. S1 did not have the H serotype defined in the current database. S1 and S2 differed by 28 267 single-nucleotide polymorphisms (SNPs), and no homologous strains were found in comparison with the data in the GeneBank database. ConclusionTwo strains of Escherichia albertii are initially identified in Baoshan District of Shanghai. Strain S1 shows strong multidrug resistance, while strain S2 carries diarrheagenic virulence genes. The two strains have a distant genetic relationship and exhibits a pattern of sporadic occurrence. It is recommended to utilize whole-genome sequencing technology to enhance the epidemiological surveillance and laboratory detection of Escherichia albertii.
8.Systematic review and Meta analysis of the effect of sleep on subsequent day physical activity among children and adolescents
Chinese Journal of School Health 2025;46(12):1781-1786
Objective:
To explore the effects of sleep on subsequent day physical activity (PA) in children and adolescents, so as to provide a reference for refining PA intervention strategies and further investigating their underlying mechanisms.
Methods:
Through searching databases including Web of Science Core Collection, PubMed, EBSCOhost, ScienceDirect, Cochrane Library, CNKI, Wanfang and VIP cross sectional, cohort and experimental studies on sleep and subsequent day PA among children and adolescents were identified, with the searching period spanning from database inception to June, 2025. Based on the characteristics of the included literature, two sleep variables[sleep duration (SD) and sleep efficiency (SE)] and three physical activity variables[moderate to vigorous physical activity (MVPA), light physical activity (LPA), and total physical activity (TPA)] were selected. The relationship between these two types of variables was analyzed for pooled effect sizes using Stata 17.0.
Results:
A total of 14 studies were included, with 64.3% published in 2018 or later, involving 11 361 children and adolescents from 17 countries. Meta analysis results showed that both SD ( ES=0.04, 95%CI =0.01-0.07) and SE ( ES=0.24, 95%CI =0.01-0.47) were positively correlated with subsequent day MVPA (both P <0.05). However, no statistically significant associations were found with LPA ( ES=-0.04, 95%CI =-0.13 to 0.06; ES=-0.02, 95%CI =-0.15 to 0.11) or TPA( ES=0.09, 95%CI =-0.02 to 0.20; ES=0.02, 95%CI = -0.03 to 0.06)(all P >0.05). Subgroup analysis revealed that in the "≤6 years" subgroup, SD and SE were positively correlated with TPA ( ES=0.22, 95%CI =0.09-0.35) and MVPA ( ES=1.19, 95%CI =1.06-1.32), respectively; in the "6-12 years" subgroup, SD was positively correlated with MVPA ( ES=0.05, 95%CI =0.02-0.08); in the "≥12 years" subgroup, SE was positively correlated with LPA ( ES=0.08, 95%CI =0.00-0.16), while SD was negatively correlated with LPA ( ES=-0.23, 95%CI = -0.31 to -0.16) (all P <0.05).
Conclusion
Adequate SD and good SE can effectively enhance subsequent day MVPA among children and adolescents, although these sleep effects vary by age group.
