The leaves of sea buckthorn(Hippophae rhamnoides), considered as common food raw materials, have records of medicinal use and diverse pharmacological activities, showing a potential medicinal value. However, the active substances in the sea buckthorn leaves and their mechanisms of action remain unclear. In addition, due to the extensive source and large variety variations, the quality evaluation criteria of sea buckthorn leaves remain to be developed. To solve the problems, this study predicted the main active components, core targets, key pathways, and potential pharmacological effects of sea buckthorn leaves by network pharmacology and molecular docking. Furthermore, ultra-performance liquid chromatography with diode-array detection(UPLC-DAD) was employed to determine the content of active components and establish the chemical fingerprint, on the basis of which the quality markers of sea buckthorn leaves were predicted and then verified by the enzyme activity inhibition method. The results indicated that sea buckthorn leaves had potential therapeutic effects on a variety of digestive tract diseases, metabolic diseases, tumors, and autoimmune diseases, which were consistent with the ancient records and the results of modern pharmacological studies. The core targets of sea buckthorn leaves included PTPN11, AKT1, PIK3R1, ESR1, and SRC, which were mainly involved in the PI3K-AKT, MAPK, and HIF-1 signaling pathways. In conclusion, the active components of sea buckthorn leaves are associated with the rich flavonoids and tannins, among which quercitrin, narcissoside, and ellagic acid can be used as the quality markers of sea buckthorn leaves. The findings provide a reference for the quality control and further development and utilization of sea buckthorn leaves as medicinal materials.

Objective: To compare the effects of the China Children's Asthma Action Plan (CCAAP)-based remote joint management model with traditional management model on the control of childhood asthma. Methods: A retrospective cohort study was conducted to analyze the general data and asthma control assessment data of 219 children with asthma who attended the respiratory department of Guangzhou Women's and Children's Medical Center from April 2021 to October 2021 and were followed up for 1 year or more. According to the follow-up management model, the CCAAP-based remote joint management model was used in the observation group and the traditional management model was used in the control group, and the propensity score matching method was applied to match the data of children in the two management models for comparison. Paired-samples t-test, Wilcoxon signed-rank test, McNemar χ2-test or χ2-test or nonparametric tests were used to compare the general data and asthma control assessment data between the two matched groups of children. Results: Among 219 children with asthma, 145 were male and 74 were female, aged at consultation (7.2±2.4) years. There were 147 cases in the observation group and 72 cases in the control group, and 27 cases in each of the observation and control groups were successfully matched. The number of asthma exacerbation aura, acute exacerbations, and emergency room visits or hospitalizations for asthma exacerbations were lower in the observation group than in the control group after pairing (1 (0, 2) vs. 3 (1, 5) times, 0 (0,0) vs. 0 (0, 1) times, 0 (0,0) vs. 1 (0, 1) times, Z=-3.42, -2.58, -3.17, all P<0.05). The use of peak flowmeters was higher in children aged 5 years and older in the observation group than in the control group after pairing (100% (22/22) vs. 13% (3/23), χ2=54.00,P<0.001). The ratio of actual to predicted 1st second expiratory volume of force after follow-up in the observation group after pairing was higher than that before follow-up in the observation group and after follow-up in the control group ((95±11)% vs. (85±10)%, (95±11)% vs. (88±11)%, t=-3.40, 2.25, all P<0.05). The rate of complete asthma control after follow-up was higher in both the observation and control groups after pairing than before follow-up for 12 months in both groups (93% (25/27) vs. 41% (11/27), 52% (14/27) vs. 41% (11/27), H=56.19, 45.37, both P<0.001), and the rate of complete control of asthma in children in the observation group was higher than that in the control group at 3 and 12 months of follow-up management (56% (15/27) vs. 25% (5/20), 93% (25/27) vs. 52% (14/27), χ2=47.00, 54.00, both P<0.001). The number of offline follow-up visits, inhaled hormone medication adherence scores, and caregiver's asthma perception questionnaire scores were higher in the observation group than in the control group after pairing (6 (4, 8) vs. 4 (2,5), (4.8±0.3) vs. (4.0±0.6) score, (19.3±2.6) vs. (15.2±2.7) score, Z=6.58, t=6.57, 5.61, all P<0.05), and the children in the observation group had lower school absences, caregiver absences, asthma attack visit costs, and caregiver PTSD scores than the control group (0 (0,0) vs.3 (0, 15) d, 0 (0,0) vs. 3 (0, 10) d, 1 100 (0, 3 700) vs. 5 000 (1 000, 10 000) yuan, 1.3 (1.1, 1.9) vs. 2.0 (1.2, 2.7) score, Z=-2.89, -2.30, 2.74, 2.73, all P<0.05). Conclusion: The CCAAP-based joint management model of asthma control is superior to the traditional management model in the following aspects: it can effectively improve asthma control, self-monitoring, and lung function in children; it can improve treatment adherence and caregivers' asthma awareness; and it can reduce the duration of absenteeism from school, the cost of asthma exacerbation visits, and caregiver's negative psychology.

OBJECTIVES:
To develop a risk prediction model for severe adenovirus pneumonia (AVP) in children, and to explore the appropriate timing for intravenous immunoglobulin (IVIG) therapy for severe AVP.
METHODS:
Medical data of 1 046 children with AVP were retrospectively analyzed, and a risk prediction model for severe AVP was established using multivariate logistic regression. The model was validated with 102 children with AVP. Then, 75 children aged ≤14 years who were considered at risk of developing severe AVP by the model were prospectively enrolled and divided into three groups (A, B and C) in order of visit, with 25 children in each group. Group A received symptomatic supportive therapy only. With the exception of symptomatic supportive therapy, group B received IVIG treatment at a dose of 1g/(kg·d) for 2 consecutive days, before progressing to severe AVP. With the exception of symptomatic supportive therapy, group C received IVIG treatment at a dose of 1 g/(kg·d) for 2 consecutive days after progressing to severe AVP. Efficacy and related laboratory indicators were compared among the three groups after treatment.
RESULTS:
Age<18.5 months, underlying diseases, fever duration >6.5 days, hemoglobin level <84.5 g/L, alanine transaminase level >113.5 U/L, and co-infection with bacteria were the six variables that entered into the risk prediction model for severe AVP. The model had an area under the receiver operating characteristic curve of 0.862, sensitivity of 0.878, and specificity of 0.848. The Hosmer-Lemeshow test showed good consistency between the predicted values and the actual observations (P>0.05). After treatment, group B had the shortest fever duration and hospital stay, the lowest hospitalization costs, the highest effective rate of treatment, the lowest incidence of complications, the lowest white blood cell count and interleukin (IL)-1, IL-2, IL-6, IL-8, IL-10 levels, and the highest level of tumor necrosis factor alpha (P<0.05).
CONCLUSIONS
The risk model for severe AVP established in this study has good value in predicting the development of severe AVP. IVIG therapy before progression to severe AVP is more effective in treating AVP in children.

Objective:
This study aimed to assess the technical feasibility, efficacy, and safety of the safe triangular working zone (STWZ) approach applied in percutaneous vertebroplasty (PV) for spinal metastases involving the posterior part of the vertebral body.
Materials and Methods:
We prospectively enrolled 87 patients who underwent PV for spinal metastasis involving the posterior part of the vertebral body, with or without the STWZ approach, from January 2019 to April 2022. Forty-nine patients (27 females and 22 males; mean age ± standard deviation [SD], 57.2 ± 11.6 years; age range, 31–76 years) were included in group A (with STWZ approach), accounting for 54 vertebrae. Thirty-eight patients (18 females and 20 males; 59.1 ± 10.9 years; 29–81 years) were included in group B (without STWZ approach), accounting for 57 vertebrae. Patient demographics, procedure-related variables, and pain relief as assessed using the visual analog scale (VAS) were collected at different time points. Tumor recurrence in the vertebrae after PV was analyzed using Kaplan–Meier curves.
Results:
The STWZ approach was successful from T1 to L5 without severe complications. Cement filling was satisfactory in 47/54 (87.0%) and 25/57 (43.9%) vertebrae in groups A and B, respectively (v< 0.001). Cement leakage was not significantly different between groups A and B (p= 1.000). Mean VAS score ± SD before and 1 week and 1, 3, 6, 9, and 12 months after PV were 7.6 ± 1.8, 4.2 ± 2.0, 2.7 ± 1.9, 1.9 ± 1.5, 1.7 ± 1.4, 1.7 ± 1.1, and 1.6 ± 1.3, respectively, in group A and 7.2 ± 1.7, 4.0 ± 1.3, 3.4 ± 1.6, 2.4 ± 1.2, 1.8 ± 1.0, 1.4 ± 0.5, and 1.7 ± 0.9, respectively, in group B. Kaplan–Meier analysis showed a lower tumor recurrence rate in group A than in group B (p = 0.001).
Conclusion
The STWZ approach may represent a new, safe, alternative/auxiliary approach to target the posterior part of the vertebral body in the PV for spinal metastases.

Objective In emergency situations where simultaneous immunization by multiple vaccines are required,how to rapidly evaluate the effect of combined immunization is an urgent issue that needs to be solved.This study aimed to investigate the po-tential role and application value of the phenotypic changes of macrophages in rapid evaluation of the effect of combined Yersinia pestis and Brucella bovis vaccine immunization at early stage.Methods Y.pestis and B.bovis vaccines were injected into mice alone or in combination to establish animal models.The changes of the macrophage phenotypes(M1 or M2 polarization)and the CD8+T cell pheno-types and functions were detected in the early(4 d)and the late(14 d)stage of the immunization,respectively.The effect of the immuno-phenotype of macrophages at early stage on the function of CD8+T cells at late stage was analyzed.Results The co-immunization by Y.pestis and B.bovis vaccines led to the attenuation of the M1-polarization of macrophages at early stage,which were marked by de-creased expression of CD16/32 and increased expression of Detectin-1 on cell surface as well as decreased expression of IL-12 and in-creased expression of IL-4 inside the macrophage,in comparison with single vaccine groups,suggesting an interference between the two vaccines.Meanwhile,the activity of CD8+T cells(including the ratio of CD8+CD69+T,CD8+IFN-γ+T and CD8+GranzymeB+T cells) in combined immunization group showed similar tendency to the attenuated phenotypic M1-polarization of macrophages. Conclusion The phenotype of macrophages at the early stage of the co-immunization by Y.pestis and B.bovis vaccines showed consistency with the phenotype and function of CD8+T cells at late stage.It might give us some hint about the possibility of utilizing the phenotypic changes of macrophages to rapidly evaluate the effect of the co-immunization at early stage.

In aged patients, acute kidney injury (AKI) is a common clinical complication after percutaneous coronary intervention (PCI), highlighting the need for timely and certain diagnosis of this disease. A single centre, nested case-control study was conducted, which assessed the usefulness of urinary liver-type fatty acid-binding protein (uL-FABP), neutrophil gelatinase-associated lipocalin (uNGAL), and kidney injury molecule-1 (uKIM-1) for early detection of AKI. One hundred and thirty-two patients at or over 60 years old undergoing PCI were included. Serum creatinine (SCr) was measured before PCI, 24 and 48 h after PCI; uL-FABP, uNGAL, and uKIM-1 were measured before PCI, 6, 24, and 48 h after PCI. We identified 16 AKI patients and selected 32 control patients matched by admission time (<1 week), age (±5 years), and gender. In the receiver operating characteristic (ROC) curve analysis, the areas under the curve (AUCs) for the relative measurements of uL-FABP, uNGAL, and uKIM-1 were 0.809, 0.867, and 0.512 at 6 h after PCI, and 0.888, 0.840, and 0.676 at 24 h after PCI, respectively. AUC for the combination of uL-FABP and uNGAL was 0.899 at 6 h after PCI, and 0.917 at 24 h after PCI. Thus, measurement of uL-FABP and uNGAL levels at 6 and 24 h after PCI may be useful in detecting AKI in aged patients. Measurement of uKIM-1 levels provides inferior predictive power for early diagnosis of AKI.

Data mining method was adopted to collect 159 cases of German migraine patients who live in the TCM-Klinik Bad Kötzting Hospital from January 2013 to March 2015. The general case information was divided into age, gender, profession, characteristics of headache, degree of headache, accompanied symptoms and tongue pulse, and included in corresponding databases. Initial data was standardized and cleaned to get a data form suitable for analysis. SPSS system software was adopted to make a frequency statistics analysis for such variables as gender, age, profession, headache characteristic and accompanied symptoms. The results showed that German migraine cases feature a universality of age, long disease cycle and easy recurrence; And most of the patients were mental workers. There were two common clinical TCM symptoms, namely hyperactivity of liver Yang type and Qi deficiency & phlegm dampness. The common symptoms are forehead tingling, recurrent headache, vomiting and nausea, dark tongue, thin and white fur tongue, wiry pulse and slippery pulse. The disease is related to the pathology of stagnation of Qi, phlegm and blood stasis in liver, spleen, kidney and stomach.

PURPOSE: Although the polymorphisms of erythrocyte complement receptor type 1 (CR1) in patients with malaria have been extensively studied, a question of whether the polymorphisms of CR1 are associated with severe malaria remains controversial. Furthermore, no study has examined the association of CR1 polymorphisms with malaria in Chinese population. Therefore, we investigated the relationship of CR1 gene polymorphism and malaria in Chinese population. MATERIALS AND METHODS: We analyzed polymorphisms of CR1 gene rs2274567 G/A, rs4844600 G/A, and rs2296160 C/T in 509 patients with malaria and 503 controls, using the Taqman genotyping assay and PCR-direct sequencing. RESULTS: There were no significant differences in the genotype, allele and haplotype frequencies of CR1 gene rs2274567 G/A, rs4844600 G/A, and rs2296160 C/T polymorphisms between patients with malaria and controls. Furthermore, there was no association of polymorphisms in the CR1 gene with the severity of malaria in Chinese population. CONCLUSION: These findings suggest that CR1 gene rs2274567 G/A, rs4844600 G/A, and rs2296160 C/T polymorphisms may not be involved in susceptibility to malaria in Chinese population.
