Fabry disease, a rare genetic disorder affecting multiple organs, has understudied correlations among enzyme activity, genotype, and clinical manifestations in patients of different sexes with classical and late-onset phenotypes. In this study, clinical data, α-Gal A activity, and GLA gene test results of 311 patients, who were categorized by classical and late-onset phenotypes, ⩽5% and > 5% of the normal mean value of enzyme activity, and truncated and nontruncated mutation groups, were collected. The common clinical manifestations of Fabry disease included acroparesthesia, hypohidrosis/anhidrosis, neuropsychiatric system, and renal and cardiovascular involvement. Multiorgan involvement was higher in males and classical phenotype patients. In both sexes, classical patients commonly presented with acroparesthesia and multiorgan involvement, whereas late-onset patients showed renal, neuropsychiatric, and cardiovascular involvement. Male and classical patients had lower enzyme activity than female and late-onset patients, respectively. Classical males with enzyme activity of ⩽5% of the normal mean level showed higher multiorgan involvement frequency than those with enzyme activity of > 5%, whereas no significant difference was observed among females. Ninety-five gene mutation sites were detected, with significant phenotype heterogeneity in patients with the same mutation. No significant difference in enzyme activity or clinical manifestations was observed between truncated and nontruncated mutations. Overall, male patients with Fabry disease, regardless of classical or late-onset phenotype, have a higher frequency of multiple-organ involvement and lower α-Gal A activity than female patients. α-Gal A activity was closely correlated with clinical symptoms in males but weakly correlated with clinical manifestations in females. The clinical manifestations of patients with the same mutation are heterogeneous, and the correlation between gene mutation and enzyme activity or clinical manifestation is weak.

Objective:To explore the value of intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) parameters in different regions of the kidney in distinguishing IgA nephropathy (IgAN) patients from healthy volunteers.Methods:This study was a cross-sectional study. Eighty-four patients diagnosed with IgAN (IgAN group) who underwent renal biopsy (lower pole of the left kidney) and were pathologically confirmed at the First Medical Center of PLA General Hospital from February 2022 to September 2023 and thirty-four healthy volunteers (control group) were included prospectively. The regions of interest were outlined in the right renal cortex, medulla, and parenchyma for all subjects, and the apparent diffusion coefficient (ADC), true diffusion coefficient (D), pseudo-diffusion coefficient (D *), and perfusion fraction (f) were measured in the corresponding regions. The differences in IVIM-DWI parameters between the IgAN group and the control group were compared using the student′s t-test or the Mann-Whitney U test. Receiver operating characteristic curve analysis was performed on the parameters with statistically significant differences, and the area under the curve (AUC) was calculated. Results:There were statistically significant differences in renal cortical ADC, renal parenchymal ADC, renal cortical D, renal parenchymal D, and renal medullary f values between the IgAN group and the control group ( Z=-3.03, -2.21, -2.62, -2.03, -2.03; P=0.002, 0.027, 0.009, 0.043, 0.042). The AUCs (95% CI) for diagnosing IgAN using renal cortical ADC, renal parenchymal ADC, renal cortical D, renal parenchymal D, and renal medullary f values were 0.679 (0.586-0.762), 0.630 (0.537-0.717), 0.654 (0.535-0.774), 0.619 (0.497-0.742), and 0.620 (0.495-0.745), respectively. There were no statistically significant differences in renal medullary ADC, D, renal cortex, medulla and parenchyma D *, renal cortical and renal parenchymal f values between the two groups ( P>0.05). Conclusion:The quantitative parameters of renal IVIM-DWI are influenced by different measurement regions, among which the ADC, D of renal cortex and parenchyma, and f of renal medulla can be used for the initial diagnosis of IgAN.

ObjectiveTo identify the chemical components of Houpo Wenzhongtang in vivo and in vitro and to analyze the pharmacokinetic properties of the index components in rats with deficiency-cold of spleen and stomach. MethodThe chemical components of Houpo Wenzhongtang was analyzed and identified by ultra performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry（UPLC-Q-TOF-MS/MS）. Six rats were randomly selected from 18 SD rats as the blank group， and the remaining rats were given lard and cold vinegar for a long time to construct a rat model with deficiency-cold of spleen and stomach. After successful modeling， the rats were randomly divided into the model group and Houpu Wenzhongtang group（13.5 g·kg^-1， calculated as crude drug）. The administration group was given the corresponding dose of Houpu Wenzhongtang by gavage， and the blank group and the model group were given the same amount of distilled water by gavage. Enzyme-linked immunosorbent assay（ELISA） were used to measure gastrin（GAS） and motilin（MTL） levels in each group. At the same time， plasma samples were collected at different time points after administration， and blood-entry prototype components and metabolites of Houpo Wenzhongtang were analyzed by UPLC-Q-TOF-MS/MS. On this basis， plasma concentrations of magnolol， honokiol， alpinetin and hesperidin in Houpo Wenzhongtang were determined by ultra performance liquid chromatography coupled with triple quadrupole/linear ion trap mass spectrometry（UPLC-QTRAP-MS/MS）， and the pharmacokinetic parameters were calculated using DAS 2.0 software. ResultA total of 79 chemical components， including 44 flavonoids and 11 lignans， were identified in Houpo Wenzhongtang. Meanwhile， 18 blood-entry prototype components and 27 metabolites were identified， the main metabolic pathways of metabolites were glucuronidation， sulfation， oxidation and hydrolysis， and phase Ⅰ and phase Ⅱ were the two primary forms of metabolism. Pharmacokinetic results showed that among the four index components， the time to peak（t_max） values of magnolol and honokiol were consistent and exhibited similar drug metabolism characteristics， the t_max of alpinetin was the shortest， and the absorption rate was the fastest， which had the earliest peak plasma concentration levels， and hesperidin had the shortest mean residence time（MRT_0-t） and the highest metabolic rate in rats. ConclusionThis study clarifies the blood-entry prototype components and their metabolites of Houpo Wenzhongtang in the rat model of deficiency-cold of spleen and stomach， and reveals the pharmacokinetic characteristics of the main active ingredients， which can provide a scientific basis for the study of pharmacodynamic material basis of this formula and its clinical application in treating the syndrome of deficiency-cold of spleen and stomach.

In order to achieve the goal of integration, homogeneity, a net and a center of medical groups in Hainan province, Hainan province built an integrated management information platform of urban medical alliances and county medical communities based on projects such as the provincial three medical linkage information platform in February 2022. The overall architecture of the medical alliance and medical community platform was divided into system integration layer, data center layer, service layer and application layer. The service layer included four major systems: unified operation management platform, business center, performance evaluation management platform and comprehensive supervision subsystem, which was the core hub connecting the data center layer and application layer, and also was the unified operation and closed-loop management platform of the medical alliance and medical community. As of November 2022, the platform had covered 31 medical alliances or medical communities in 19 cities and counties of Hainan province, achieving information exchange, personnel interaction, resource sharing, business collaboration, and data integration among member units, narrowing the gap between urban and rural medical and health services, which had preliminarily achieved homogeneous management of the medical alliances and medical communities throughout the province, for a reference for the integrated management of medical alliances and medical communities within the regional scope of China.

ObjectiveTo explore the clinical effect of core muscle motor control training on postpartum diastasis recti abdominis. MethodsFrom January, 2021 to January, 2022, 30 outpatients with postpartum diastasis recti abdominis were randomly divided into control group (n = 15) and experimental group (n = 15). Manipulative therapy and breathing training were performed simultaneously in both groups. Besides, the control group received conventional core strength training, and the experimental group received core muscle motor control training, for four weeks. Their distance of diastasis recti abdominis, abdominal circumference and waist circumference were compared before and after treatment. ResultsAfter treatment, the distance of diastasis recti abdominis, abdominal circumference and waist circumference reduced in both groups (Z = 3.408, t > 5.927, P < 0.05). The reduction value of diastasis recti abdominis distance was more in the experimental group than in the control group (t = 2.328, P < 0.05). ConclusionCore muscle motor control training can effectively relieve postpartum diastasis recti abdominis, and the effect is better than conventional core strength training.

Objective: To explore the relationship between different serum albumin and lymphocyte levels in patients with 2019-novel coronavirus (2019-nCoV) pneumonia (COVID-19). Methods: A retrospective study was performed to identify the characteristics of the clinical data of 205 COVID-19 patients who were hospitalized in the Happy Street of Hanchuan People's Hospital, Xiaogan, Hubei Province from January 24 to February 12, 2020, including their general information, serum albumin (ALB) levels, lymphocyte counts (LYM), percentage of lymphocytes (LYM%) and other laboratory parameter levels. Low ALB group and normal ALB group were demarcated by the concentration of 35g/L, further to identify the differences of LYM and LYM% levels and the incidence of LYM and LYM% decline at different ALB levels between groups,as well as the correlation between ALB and LYM, LYM% levels in hypoalbuminemia conditions . Results: 17.5% of COVID-19 patients were associated with hypoalbuminemia. The levels of LYM and LYM% in the low ALB group were significantly lower than those in the normal ALB group (P <0.001). The incidence of LYM and LYM% decline in the low ALB group was significantly higher than those in the normal ALB group (P <0.001). The levels of LYM and LYM% in the low ALB group were significantly positively correlated with serum ALB concentrations (P <0.05). Conclusions The decrease of lymphocyte levels in COVID-19 patients may be correlated to hypoalbuminemia. COVID-19 patients complicated by hypoalbuminemia should be actively intervened to maintain serum albumin in the normal range.
