ObjectiveTo study the effect of Wulingsan on cerebral edema after intracerebral hemorrhage (ICH) in mice and explore the treatment mechanism. MethodsThe mouse model of ICH was established by injection of collagenase into the caudate nucleus. Mice were randomly assigned into the following groups: sham, ICH, intervention before modeling with low-dose and high-dose (3.69, 11.07 g·kg-1, respectively) Wulingsan, and intervention after modeling with high-dose Wulingsan. The modified neurological severity score (mNSS) was recorded, and the small animal MRI T2 sequential scanning was performed to measure the volume of cerebral hemorrhage after the modeling of ICH in each group. The Y-maze test, open field test, and Morris water maze test were conducted to evaluate the neurological behaviors of mice in each group. Hematoxylin-eosin staining was employed to observe the pathological changes in the brain tissue. Immunohistochemistry was employed to observe the expression of aquaporin 4 (AQP4), neuronal nuclei (NeuN), and glial fibrillary acidic protein (GFAP) in the brain tissue. Western blot was employed to determine the protein levels of AQP4, Claudin-5, and zonula occludens-1 (ZO-1) in the hematoma area. ResultsCompared with the sham group, the ICH group showed increases in the mNSS, the cerebral hemorrhage volume, and the escape latency in the Morris water maze test (P<0.01), decreases in the times of touching the platform and times of entering the quadrant where the platform was located in the Morris water maze test, and reductions in the spontaneous alternation rate in the Y-maze test and the ratio of distance of center travel to total travel distance in the open field test (P<0.01). Moreover, pathological changes such as cell disarrangement, cell space enlargement, and cell swelling were observed in the ICH group. Immunohistochemistry results showed that the ICH group had higher proportions of AQP4- and GFAP-positive cells and lower proportion of NeuN-positive cells than the sham group (P<0.01). Compared with the sham group, the ICH group showed an up-regulated protein level of AQP4 and down-regulated protein levels of Claudin-5 and ZO-1 (P<0.01). Compared with the ICH group, the intervention with Wulingsan decreased the mNSS, the volume of cerebral hemorrhage, and the escape latency in the Morris water maze test (P<0.05, P<0.01), while increasing the times of touching the platform and times of entering the quadrant where the platform was located in the Morris water maze test, the spontaneous alternation rate in the Y-maze test, and the ratio of distance of center travel to total travel distance in the open field test (P<0.05, P<0.01). Furthermore, the intervention with Wulingsan alleviated the pathological changes in the brain tissue after ICH, decreased the proportion of AQP4- and GFAP-positive cells (P<0.01), increased the proportion of NeuN-positive cells (P<0.01), down-regulated the protein level of AQP4 (P<0.01), and up-regulated the protein levels of Claudin-5 and ZO-1 (P<0.01). ConclusionThe intervention with Wulingsan could reduce the neural function score and the cerebral hemorrhage volume, up-regulate the expression of Claudin-5 and ZO-1, and down-regulate the expression of AQP4 to ameliorate the neurological function defect and cerebral edema after ICH, thereby protecting the brain.

Abstract
To analyzes the characteristics, problems and enlightenment of physical activity observation tools, so as to provide reference for researchers to quickly and accurately choose appropriate observation tools to evaluate children s and adolescents physical activity. Literature search is conducted in eight databases of Chinese and English, including CNKI, Wanfang, VIP, Web of Science, PubMed, Medline, ERIC, and SPORTDiscus. Ultimately, eight observation tools for assessing physical activity in children and adolescents are included. Through summarization and comparison, it is found that the applications of those tools cover multiple age groups, the observation indicators cover multiple dimensions for each with varying emphases, and the applicable contexts vary in their specific background information, and recording methods tend to be quantitative. However, several issues remain to be addressed in practical applications. First, the observation indicators need to be supplemented and improved; second, physical activity in community environments and academic classrooms requires further attention; third, physical activity intensity needs to be scientifically evaluated; fourth, observation and recording methods need to be integrated and innovated; fifth, the number of observation subjects needs to be expanded. Future research could focus on developing observation tools tailored to the characteristics of Chinese children and adolescents, while drawing on foreign observation tools to comprehensively assess physical activity among children and adolescents.

OBJECTIVE To investigate the monitoring of tacrolimus blood concentration in patients with nephrotic syndrome (NS),and to establish a prediction model for tacrolimus blood concentration. METHODS Data from 509 concentration monitoring sessions of 166 NS patients using tacrolimus were collected from January 1, 2020 to August 31, 2023 in Zhongshan Hospital Affiliated to Xiamen University. The relationship of efficacy and adverse drug reaction(ADR) with blood concentration was analyzed. A multilayer perceptron (MLP) prediction model was established by using the blood concentration monitoring data of 302 times from 109 NS patients with genetic information, and then verified. RESULTS In terms of efficacy, the median blood concentration of tacrolimus in the non-remission group was 2.20 ng/mL, which was significantly lower than that in the partial remission group (4.00 ng/mL, P<0.001) and the complete remission group (3.60 ng/mL, P=0.002). In terms of ADR, the median blood concentration of tacrolimus in the ADR group was 5.01 ng/mL, which was significantly higher than that in the non-ADR group (3.37 ng/mL) (P=0.001). According to the subgroup analysis of the receiver operating characteristic curve, when the blood concentration of tacrolimus was ≥6.65 ng/mL, patients were more likely to develop elevated blood creatinine [area under the curve (AUC) was 0.764, P<0.001); when the blood concentration of tacrolimus was ≥6.55 ng/mL, patients were more likely to develop blood glucose (AUC=0.615, P= 0.005). The established MLP prediction model has a loss function of 0.9, with an average absolute error of 0.279 5 ng/mL between the predicted and measured values. The determination coefficient of the validation scatter plot was 0.984, indicating an excellent predictive performance of the model. CONCLUSION Tacrolimus blood concentration has an impact on both efficacy and ADR in NS patients. The use of the MLP model for predicting blood concentration exhibits high accuracy with minimal error between predicted and measured values. The model can be used as an important tool in clinical individualized medication regimens.

ObjectiveTo investigate the mechanism of Zexie Decoction (泽泻汤) in inhibiting neuroinflammation and improving cognitive impairment mediated by high-calorie diet. MethodsTwenty seven C57BL/J mice were randomly divided into control group (n = 9), model group (n = 9) and Zexie Decoction group (n = 9). The mice in the model group and the Zexie Decoction group were fed with high-calorie diet to establish the model of cognitive impairment. Meanwhile, the mice in Zexie Decoction group were also fed with 0.36 g/(kg·d)Zexie Decoction, and the mice in the control group and model group were fed with the same volume of normal saline for 8 weeks. The body weight of mice was recorded at the same time every week; after intervention, oral glucose tolerance test (OGTT) and insulin tolerance test(ITT) commenced; the cognitive level of mice was detected by Morris water maze, open field test, new object recognition test and Y maze; magnetic resonance spectroscopy (MRS) was used to detect the expression of N-acetylaspartate (NAA), choline (CHO), lactic acid (Lac), creatine (Cr), lipid (Lip), and myoInositol (mI) in left hippocampus, hypothalamus and cortex. Western blotting was used to detect the expression of synaptophysin (SYN), synaptosome associated protein-25 (SNAP-25), postsynaptic dense protein-95 (PSD-95), tumor necrosis factor-α (TNF-α), nuclear factor kappa B (NF-κB p65) and its phosphorylated form (P-NF-B p65) in mouse brain; Nissl's staining was used to detect the morphological changes of hippocampal neurons. ResultsCompared with the control group, body mass, blood glucose in oral glucose tolerance test, and blood glucose in insulin tolerance test increased in the model group; in the Morris water maze experiment, the total distance travelled and escape latency of the model group mice increased, the time spent in the platform area and the number of times traversing the platform decreased on days 3 and 4; in the open-field experiment, the number of times the model group mice entered the central area, the ratio of the time in the central area to the total time, and the ratio of the distance travelled in the central area to the total distance significantly decreased; in the new object recognition test, the frequency of new object recognition and recognition index were significantly lower in the model group mice; in the Y-maze test, the spontaneous alternation rate of mice in the model group was significantly lower (P<0.05 or P<0.01); in the left hippocampus, hypothalamus, and cortex of mice in the model group, the CHO/Cr, NAA/Cr significantly decreased, and the mI/Cr, Lac/Cr and Lip/Cr significantly increased; SYN/β-actin, SNAP-25/β-actin and PSD-95/β-actin values significantly decreased, and p-NF-κB p65/NF-κB p65 and TNF-α/β-actin values significantly increased in brain tissue (P<0.05 or P<0.01). Compared with the model group, the above indexes of mice in the Zexie Decoction group significantly improved (P<0.05 or P<0.01). The results of Nissl staining showed that compared with the control group, the neurons in the dentate gyrus of the hippocampus in the model group were scattered and sparsely arranged, the density was significantly reduced, the nuclei of the cells had consolidation and shrinkage, the number of Nissl vesicles was reduced, and the staining became lighter; compared with the model group, the density of neurons in the hippocampal dentate gyrus region of the Zexie Decoction group increased, the wrinkling of nuclei improved, the cell gap narrowed, and the arrangement was slightly tight. Concusion The ameliorative effect of Zexie Decoction on cognitive function in mice with high-calorie diet-induced cognitive impairment may relate to the restructuring of glucose metabolism homeostasis, inhibition of neuroinflammation, reduction of neuronal damage, and enhancement of synaptic plasticity.

Laparoscopic sleeve gastrectomy, as the significantly effective weight loss surgery currently recognized, is widely used at home and abroad, and the quality of life of postoperative patients also receives widespread attention. At present, domestic researchers often use universal scales to evaluate the quality of life of postoperative patients, but such scales cannot truly reflect the quality of life of postoperative patients. This paper reviews the universal and specific assessment tools for quality of life in patients after laparoscopic sleeve gastrectomy, elaborates on the advantages and disadvantages of each tool, compares and analyzes the specific assessment tools, and proposes the shortcomings of the specific assessment tools and future research directions. The aim is to provide a reference for selecting and developing suitable assessment tools for the quality of life of patients after laparoscopic sleeve gastrectomy in China.

With the application of accelerated rehabilitation surgery mode in metabolic bariatric surgery, the postoperative hospital stay of patients is gradually shortened, but it also leads to the lack of postoperative knowledge of patients after discharge. Adequate guidance on discharge readiness is beneficial for improving the self-management ability of patients and improving dietary, medication and exercise compliance. This paper reviews the status quo, assessment tools, influencing factors and intervention measures of discharge readiness of patients undergoing metabolic bariatric surgery, in order to provide references and ideas for developing discharge readiness evaluation tools and related studies for patients undergoing metabolic bariatric surgery in China.

Objective:To explore chromosomal copy number variations (CNVs) and pregnancy outcomes in fetuses with mild to moderate isolated ventriculomegaly (IVM), but without other indications for invasive prenatal diagnosis.Methods:A retrospective analysis was conducted on clinical data of 215 singleton pregnancies with mild to moderate IVM (lateral ventricular width≥10-<15 mm) who underwent chromosomal microarray analysis (CMA), not indicated by advanced age, high risk in serum screening or abnormal history of pregnancy, at the Fujian Maternity and Child Health Hospital between June 2016 and March 2023. The 215 fetuses were grouped into mild ( n=167) and moderate ( n=48) IVM;unilateral ( n=142) and bilateral ( n=73) IVM; first diagnosis of IVM before 28 weeks ( n=138) and thereafter ( n=77). Anomalies other than IVM were excluded via three-dimensional color Doppler ultrasound examination between 22 and 26 weeks of gestation. Out of these cases, 129 were confirmed by fetal cranial MRI, 191 underwent chromosomal karyotype analysis, and 202 cases received cytomegalovirus DNA quantification test for amniotic fluid. The detection rates of pathogenic CNVs in various groups were compared using Fisher's exact test. Results:Among the 215 fetuses, 11 cases (5.1%) of chromosomal abnormalities were detected through CMA, including one trisomy 21, five pathogenic CNVs, and five CNVs of uncertain clinical significance. Within the pathogenic CNVs, there were two de novo mutations with 16p11.2 microdeletion and one de novo mutation with 16p11.2 microduplication, while one 16p11.2 microduplication and one Xp22.31 microdeletion were inherited maternally. Of the CNVs of uncertain significance, there were two 16p13.11 microduplications, each inherited from a different parent, one paternally and one maternally; meanwhile, family validation was refused in the other three cases with 3p22.1 microdeletion, 3p26.3 microdeletion, and 9q21.33q22.31 microduplication. The detection rate of pathogenic CNVs in the moderate IVM group was higher than that in the mild IVM group [6.3% (3/48) vs. 1.2% (2/167)], but the difference was not statistically significant ( P=0.083). Similarly, no significant difference was found in the detection rate of pathogenic CNVs when comparing the unilateral IVM group [2.1% (3/142)] with the bilateral IVM group [2.7% (2/73)], nor between the group diagnosed with VM before 28 weeks gestation [2.2% (3/138)] and that diagnosed ≥28 weeks [2.6% (2/77)] (both P>0.05). After the exclusion of fetuses with chromosomal pathogenic abnormalities ( n=11), cytomegalovirus infection( n=1), and additional ultrasound anomalies ( n=7), and several cases with missing data intrauterine outcomes were followed up in 169 IVM fetuses, including 104 (61.5%) improved, 60 (35.5%) unchanged, and five (3.0%) progressed. Follow-ups were successful for 194 women, of which eight pregnancies were terminated (including one trisomy 21, four pathogenic CNVs, one fetal cytomegalovirus infection, and two progressed to severe IVM). Among the 186 newborns, one was diagnosed with X-linked ichthyosis, and one child who progressed to severe IVM before born was followed until 20 months of age without notable phenotypic abnormalities. The rest 184 babies, including those with CNVs of uncertain clinical significance, exhibited no developmental abnormalities during follow-up between the ages of three months and six years. Conclusions:For those fetuses with isolated mild to moderate IVM, but without indications for prenatal diagnosis such as advanced maternal age, high risk in serum screening or abnormal history of pregnancy, remain having the risk for chromosomal aberrations, and 16p11.2 microdeletion/microduplication might be a frequent CNV associated with this condition. Aside from those with pathogenic chromosomal aberrations, fetal cytomegalovirus infection, or progressive enlargement of the lateral ventricles, most fetuses with isolated mild to moderate IVM have a good prognosis.
