Objective To report the diagnosis of a canine distemper virus outbreak among a colony of cynomolgus monkeys at an experimental monkey farm in 2019. MethodsA total of 46 samples were collected from 21 diseased cynomolgus monkeys (exhibiting symptoms such as facial rash, skin scurf, runny nose, and diarrhea) and from one deceased monkey at an experimental monkey breeding farm in South China in late 2019, including serum, skin rash swabs, and anticoagulated whole blood, liver, lung, and skin tissues were submitted for testing. All submitted samples were tested for canine distemper virus gene fragments using real-time quantitative PCR, while immunohistochemical staining was performed to detect canine distemper virus nucleoprotein in lung tissues. The skin tissue of the deceased monkey was ground and sieved. The filtrate was inoculated into a monolayer MDCK cell line for virus isolation. Then, whole-genome sequencing was performed to identify the isolated virus. The Clustal Omega tool was used to align and analyze the homology of different Asian canine distemper virus isolates. A phylogenetic tree was constructed, followed by genetic evolutionary analysis. ResultsClinical retrospective analysis revealed that the diseased cynomolgus monkeys exhibited symptoms similar to those observed in cynomolgus monkeys infected with measles virus. Necropsy findings showed red lesions in the lungs and significant hemorrhage in the colonic mucosa. Real-time quantitative PCR detected canine distemper virus nucleic acid in the serum, skin rash swabs of the infected monkeys, and various tissue samples of the deceased monkey, all of which tested positive. Calculation based on the standard curve formula indicated the viral load was highest in the skin tissue. Immunohistochemical staining of the deceased monkey's lung tissue demonstrated aggregation of CDV nucleoprotein in alveolar epithelial cells, bronchi, and bronchioles. A CDV strain was isolated from the skin tissue of the deceased monkey. Phylogenetic analysis indicated that this strain shares the closest relationship (98.86%) with the Asian-1 type canine distemper virus strain CDV/dog/HCM/33/140816, previously identified in dogs in Vietnam. ConclusionBased on comprehensive analysis of clinical symptoms, nucleic acid detection, viral protein immunohistochemistry, and whole-genome sequencing results, the diagnosis confirms that the cynomolgus monkeys in this facility are infected with canine distemper virus. It is recommended to include canine distemper virus as a routine surveillance target in captive monkey populations. Additionally, this study provides a foundation for further research on the molecular biological characteristics of canine distemper virus.

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 analyze the influencing factors of voriconazole trough concentration and adverse drug reactions (ADR) in renal transplant recipients. METHODS Data from inpatients who received voriconazole and therapeutic drug monitoring in our hospital between January 2022 and August 2023 were retrospectively analyzed. Patients were divided into renal transplant group and non-renal transplant group based on transplantation status. A 1∶1 propensity score matching (PSM) method was used to balance differences in baselines between the two groups. Voriconazole trough concentrations, target attainment rate, clinical efficacy, and ADR were compared between the two groups. Multiple linear regression (backward) was used to analyze the factors influencing voriconazole trough concentrations in the renal transplant group. Univariate analysis and binary Logistic regression were used to identify independent risk factors for ADR in the renal transplant group. RESULTS After PSM, 48 patients were included in each group. There were no statistically significant differences in the mean voriconazole trough concentration, target attainment rate or efficacy rate between the two groups (P>0.05). The total incidence of ADR was significantly higher in the renal transplant group than in the non-renal transplant group (P<0.05). Multiple linear regression analysis showed that age, average daily dose, pulmonary infection, total bilirubin during medication, day-1 loading dose, use of the original drug, concomitant immunosuppressant use, and the occurrence of ADR were factors influencing voriconazole trough concentration in renal transplant patients (P<0.05). Binary Logistic regression analysis showed that abnormal direct bilirubin during medication [OR=7.747, 95%CI (1.334, 45.005), P=0.023] was an independent risk factor for ADR in renal transplant patients receiving voriconazole. CONCLUSIONS Age, average daily dose, pulmonary infection, use of the original drug, day-1 loading dose, total bilirubin during medication, concomitant immunosuppressant use, and the occurrence of ADR are the factors influencing voriconazole trough concentration in renal transplant patients. Furthermore, patients with abnormal direct bilirubin during medication are more susceptible to ADR.

AIM: To analyze the reasons and clinical outcomes of intraocular lens(IOL)exchange.METHODS:This retrospective case series study included 47 patients(53 eyes)who underwent IOL exchange surgery at the Department of Ophthalmology, the First Affiliated Hospital of Zhengzhou University, between April 2020 and May 2024, aged from 5 to 87(44.8±3.6)years old. Patients' demographics, surgical indications, surgical techniques, preoperative and postoperative uncorrected visual acuity(UCVA)and best-corrected visual acuity(BCVA), as well as postoperative complications were recorded.RESULTS:The reasons for IOL exchange included refractive error(18 cases, 23 eyes, 43%), IOL dislocation(12 cases, 13 eyes, 25%), IOL opacification(12 cases, 12 eyes, 23%), neuroadaptation failure(3 cases, 3 eyes, 6%), and patient dissatisfaction with visual quality(2 cases, 2 eyes, 4%). The surgical techniques for IOL exchange included in-the-bag IOL fixation(16 eyes, 30%), ciliary sulcus fixation(27 eyes, 51%), and scleral suture fixation(10 eyes, 19%). There was statistical significant difference between preoperative UCVA(LogMAR)and UCVA(LogMAR)at 1 d postoperatively(1.03±0.64 vs 0.50±0.46, P<0.05), and there was statistical significant difference between preoperative BCVA(LogMAR)and BCVA(LogMAR)at 1 mo postoperatively(0.41±0.37 vs 0.17±0.21, P<0.05). Postoperative complications included posterior capsule opacification in 2 eyes and IOL dislocation in 1 eye.CONCLUSION:Refractive error, IOL dislocation, and IOL opacification were the three most common reasons for IOL exchange. Although less frequent, factors such as neuroadaptation issues associated with multifocal IOLs and patient-reported visual quality dissatisfaction reflect growing expectations for improved visual outcomes. IOL exchange surgery, though technically challenging, demonstrates favorable clinical efficacy and a low complication rate, representing an effective intervention for managing postoperative IOL-related issues following cataract surgery.

Objective:To investigate the changes of brain microstructure in active Crohn's disease (CD) patients with or without anxiety by diffusion kurtosis imaging (DKI), and to explore the relationship between brain microstructure and anxiety in patients with CD.Methods:Thirty-seven patients with CD who were treated in Changzhou Second People's Hospital Affiliated to Nanjing Medical University from January 2022 to January 2023 were included as the CD group, and 20 healthy subjects were included as the healthy control group during the same period. All subjects were assessed with hospital anxiety and depression scale-anxiety (HADS-A) before magnetic resonance imaging(MRI) scan. According to the HADS-A score, CD patients were divided into the CD group with anxiety (16 cases) and the CD group without anxiety (21 cases). After MRI scan, DKI parameters were obtained by DKE software. One-way analysis of variance was used to compare DKI parameters between the two groups of CD patients and the healthy control group. Pearson correlation was used to analyze the correlation between DKI parameters in different brain areas and psychological scale scores in the two groups of CD patients.Results:The axial diffusion kurtosis(AK)values in the right insula, the left superior temporal gyrus, the right thalamus, the left middle temporal gyrus, the right inferior temporal gyrus, the left lingual gyrus and the right anterior cuneus were significantly different among the three groups ( F=3.060-9.627, all P<0.05).There were significant differences in the radial diffusion kurtosis(RK) values in the right cerebellar region 6 and the left hippocampus among the three groups ( F=4.124, 3.536, 4.200, all P<0.05). Further multiple comparison results showed that the AK values of the right insula (0.701±0.028)( P=0.019), the left superior temporal gyrus (0.764±0.016)( P=0.002) and the right thalamus (0.728±0.016)( P=0.001) in the CD group without anxiety were lower than those of the healthy control group(0.726±0.010, 0.780±0.015, 0.771±0.082), and the RK value of the right cerebellar region 6 ( P=0.021) was lower than that of the healthy control group. The AK values of the right insula ( P=0.023), the left superior temporal gyrus ( P=0.015), the right thalamus ( P=0.031), the left middle temporal gyrus ( P=0.006), the right inferior temporal gyrus ( P=0.001) and the left lingual gyrus ( P=0.007) in the CD group with anxiety were lower than those in the healthy control group. The RK values of right cerebellar region 6 ( P=0.012) and left hippocampus ( P=0.004) were lower than those of healthy control group. The AK values of the right insula ( P=0.002) and the right anterior cuneus ( P=0.017) in the group with anxiety were lower than those in the CD group without anxiety. In the CD group with anxiety, the AK value of the right insula was correlated with erythrocyte sedimentation rate(ESR)( r=-0.47, P=0.048), HADS-A score ( r=-0.68, P=0.002), SES-CD( r=-0.84, P<0.001) and duration of disease ( r=-0.61, P=0.008) were negatively correlated. AK values in the left superior temporal gyrus with anxiety CD group were negatively correlated with HADS-A score ( r=-0.51, P=0.030) and SES-CD score ( r=-0.48, P=0.046). Conclusion:The microstructure of some brain regions was damaged in CD patients with or without anxiety, which was manifested as decreased RK and AK values in DKI parameter values, which may be related to the anxiety state in active CD patients.

bstract: Objective To elucidate the distribution characteristics of mosquito species and the population genetic
diversity of important mosquito species in the Wuyi Mountain Nature Reserve, with the aim of providing a scientific basis for
the prevention and control of mosquito-borne diseases in the region. Methods Within Wuyi Mountain Nature Reserve 2022-
2023, 16 sampling sites were selected, where larvae were collected using the pipette method and adult mosquitoes were
collected using the mosquito trap lamp method. Mosquito species identification was accomplished by integrating morphological
characteristics and molecular identification techniques based on CO Ⅰ and CO Ⅱ gene sequences. Software tools such as
ClustalX, DnaSP v5.0, and Network v4.6.1.0 were utilized to analyze the genetic differentiation (Fst), gene flow (Nm) among
populations of Aedes japonicus, Aedes albopictus and Armigeres subalbatus. Results The mosquito specimens collected from
the Wuyi Mountain Nature Reserve were identified as 30 species belonging to 8 genera within the Culicidae family. Among
them, there were 10 species of Aedes, 13 species of Culex, 1 species each of Armigeres, Orthopodomyia, Uranotaenia,
Tripyeroides, and Anopheles, and 2 species of Toxorhynchites. Analysis of the genetic structure of important mosquito
populations showed that the haplotype diversity index (Hd) of Ae. japonicus was 0.994 7, with a generally moderate degree of
differentiation between populations and a higher degree of genetic differentiation between populations 6 and 12; Aedeslbopictus had a haplotype diversity index of 0.634 0, with significant genetic differentiation between populations 1 and 2
compared to other groups; Armigeres subalbatus had a haplotype diversity index of 0.703 3, with substantial genetic
differentiation and limited gene flow between population 2 and populations 3, 4, 6, and 7. Conclusions The mosquito species
are rich in Wuyi Mountain Nature Reserve. A comprehensive survey of the composition and distribution of mosquito populations
was carried out, and the characteristics of the population genetic structure of the important species of Ae. japonicus, Ae.
Albopictus, and Ar. subalbatus populations were analyzed, providing valuable scientific data reference for local mosquito-borne
ecological research and disease prevention and control.

The construction of healthy schools is one of the key measures to implement the Outline of the Healthy China 2030 Plan. The establishment and implementation of the Guidelines for Healthy Primary and Secondary School Evaluation (Guidelines) is helpful for the large-scale promotion and standardization of healthy school construction by government departments in Shanghai and other major cities in China, thereby more students benefited from the Healthy China Initiative. The Guidelines integrate the efforts of multiple departments related to school health, based on internationally recognized content and strategies for health-promoting schools. They aim to foster students’ health development by combining the basic requirements for school health with priority projects for health promotion. Healthy school evaluation indicators and standardized requirements suitable for the current socio-economic development level of Shanghai have been developed, aligning with international concepts of health-promoting schools. They also reflect a high starting point and high level of investment and development in school health in Shanghai over the past decade. The Guidelines provide recommendations on the basic requirements, organization guarantees and management, social and culture environment, health promotion education, health services, and connection between school and communities, and families, of healthy school evaluation for primary and secondary schools. This paper aims to interpret the compilation process and main content of the Guidelines.

Blinding is an important means to control and reduce measurement bias in clinical research, and blinding assessment is the main method to measure the success of the blinding method. By summarizing the current situation of blinding assessment in randomized controlled trials (RCT) of acupuncture, it was found that the report rate of blinding assessment by acupuncture RCT was relatively low, and the studies reporting blinding assessment had several problems, such as incomplete assessment individuals, unreasonable assessment questionnaires, and unscientific analysis methods, and the setting of the assessment time point is controversial. Given the above problems, this paper discussed the key elements of blinding assessment individuals, assessment questionnaires, assessment time points, and analysis methods. It is suggested that blinding assessment should be carried out on all blinded participants and personnel in the study; the assessment questionnaire should be designed by direct inquiry, with responses designed using three or more categorical options that include an "unclear" option; the early stage of the trial should be taken as the mandatory time point for assessment, integrating the evaluation index of the James blinding index and the Bang blinding index, in order to standardize the application of blinding assessment in acupuncture RCT and improve the quality of acupuncture clinical research.

ObjectiveTo explore the molecular mechanism implicated in the treatment of primary myelofibrosis (PMF) using Chinese medicinal herbs (CMH) by bioinformatics and molecular dynamics. MethodsData mining was performed to find the high-frequency CMH in treating PMF between the year of 1985 and 2024 by searching CNKI, Chinese Science and Technology Journal Database (CCD), and China Academic Journal Database (CSPD). TCMSP, SwissTargetPrediction and related reports were used to collect the main active ingredients of high-frequency CMH and their targets. The PMF datasets GSE44426 and GSE124281 were downloaded from GEO database, and R software was used for data normalization and differentially expressed genes (DEGs) screening. Key module hub genes were obtained by weighted gene co-expression network analysis (WGCNA) analysis. The common intersection genes of active ingredient targets, DEGs and key module hub genes of CMH were selected, and the target network was generated using Cytoscape 3.9.2 software. The core target network was generated by topological analysis, while key pathways were selected by GO and KEGG pathway enrichment analysis, and protein interaction relationships were obtained from the String database, so as to construct drug-ingredient-target network and protein interaction network (PPI) relationship diagrams. Discovery Studio 2020 software was used to perform molecular docking, and the GROMACS program was used to perform molecular dynamics simulation. ResultsA total of 21 prescriptions were collected involving 121 herbs. There were 9 herbs with a frequency ≥10 times, which were Danshen (Radix et Rhizoma Salviae Miltiorrhizae), Huangqi (Radix Astragali), Baizhu (Rhizoma Atractylodis Macrocephalae), Danggui (Radix Angelicae Sinensis), Dangshen (Radix Codonopsis), Gancao (Radix et Rhizoma Glycyrrhizae), Baishao (Radix Paeoniae Alba), Fuling (Poria) and Shudihuang (Radix Rehmanniae Praeparata) from high- to low-frequency. A total of 98 active ingredients and 1125 potential targets were obtained from 9 high-frequency CMH. GSE44426 and GSE124281 data sets screened out 24 gene samples, including 14 of the healthy control group and 10 of the PMF group, and identified 319 DEGs between the two groups, including 122 up-regulated genes and 197 down-regulated genes. WGCNA screened out 24 co-expression module genes and found that the five modules closely related to the onset of PMF were MEpink, MEdarkred, MEblack, MEgrey, and MEturquoise, involving 7112 key module hub genes. The GO and KEGG enrichment analyses indicated that lipids and the atherosclerosis pathways were mainly involved in the mechanism of above high-frequency CMH in treating PMF, which included six hub protein targets: HSP90AA1, HSP90AB1, SRC, MAPK1, IL1B and IL10. From the drug-ingredient-target network, seven active ingredients of CMH targeting at these six hub targets were found, including verbascoside, verbascos isoflavone, kaempferol, luteolin, naringenin, quercetin and pachymic acid. The molecular docking and molecular dynamics analyses showed that the key CMH were Shudihuang, Huangqi, Baishao, Danshen, Gancao and Fuling, and among the seven active ingredients, calycosin had the highest binding affinity with HSP90AB1. ConclusionThe main CMH for the treatment of PMF may be Shudihuang, Huangqi, Baishao, Danshen, Gancao and Fuling, and the active ingredients include verbascoside, verbascos isoflavones, kaempferol, luteolin, naringenin, quercetin and pachymic acid. The relevant targets are HSP90AA1, HSP90AB1, SRC, MAPK1, IL-10, and IL-1β, and the most critical pathways are lipid and atherosclerosis pathways.
