Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVE: To investigate the effectiveness of Xuanshen Yishen Decoction (XYD) in the treatment of hypertension. METHODS: Hospital electronic medical records from 2019-2023 were utilized to emulate a randomized pragmatic clinical trial. Hypertensive participants were eligible if they were aged ⩾40 years with baseline systolic blood pressure (BP) ⩾140 mm Hg. Patients treated with XYD plus antihypertensive regimen were assigned to the treatment group, whereas those who followed only antihypertensive regimen were assigned to the control group. The primary outcome assessed was the attainment rate of intensive BP control at discharge, with the secondary outcome focusing on the 6-month all-cause readmission rate. RESULTS: The study included 3,302 patients, comprising 2,943 individuals in the control group and 359 in the treatment group. Compared with the control group, a higher proportion in the treatment group achieved the target BP for intensive BP control [8.09% vs. 17.5%; odds ratio (OR)=2.29, 95% confidence interval (CI)=1.68 to 3.13; P<0.001], particularly in individuals with high homocysteine levels (OR=3.13; 95% CI=1.72 to 5.71; P<0.001; P for interaction=0.041). Furthermore, the 6-month all-cause readmission rate in the treatment group was lower than in the control group (hazard ratio=0.58; 95% CI=0.36 to 0.91; P=0.019), and the robustness of the results was confirmed by sensitivity analyse. CONCLUSIONS XYD could be a complementary therapy for intensive BP control. Our study offers real-world evidence and guides the choice of complementary and alternative therapies.

OBJECTIVE: Huachansu injection (HCSI), a promising anti-cancer Chinese medicine injection, has been reported to have the potential for reducing the toxicity of chemotherapy and improving the quality of life for colorectal cancer (CRC) patients. The objective of this study is to explore the synergistic and detoxifying effects of HCSI when used in combination with irinotecan (CPT-11). METHODS: To investigate the effect of HCSI on anti-CRC efficacy and intestinal toxicity of CPT-11, we measured changes in the biological behavior of LoVo cells in vitro, and anti-tumor effects in LoVo cell xenograft nude mice models in vivo. Meanwhile, the effect of HCSI on intestinal toxicity and the uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) expression was investigated in the CPT-11-induced colitis mouse model. Subsequently, we measured the effect of HCSI and its 13 constituent bufadienolides on the expression of UGT1A1 and organic anion transporting polypeptides 1B3 (OATP1B3) in HepG2 cells. RESULTS: The combination index (CI) results showed that the combination of HCSI and CPT-11 exhibited a synergistic effect (CI < 1), which significantly suppressing the LoVo cell migration, enhancing G2/M and S phase arrest, and inhibiting tumor growth in vivo. Additionally, the damage to intestinal tissues was attenuated by HCSI in CPT-11-induced colitis model, while the increased expression of UGT1A1 in HepG2 cells and in mouse was observed. CONCLUSION The co-therapy with HCSI alleviated the intestinal toxicity induced by CPT-11 and exerted an enhanced anti-CRC effect. The detoxifying mechanism may be related to the increased expression of UGT1A1 and OATP1B3 by HCSI and its bufadienolides components. The findings of this study may serve as a theoretical insights and strategies to improve CRC patient outcomes.

Objective:To explore the effects and potential mechanisms of chemokine-like factor-like MARVEL transmembrane domain-containing Protein 3 (CMTM3) on the proliferation and migration of glioblastoma (GBM) cells.Methods:Using CMTM3 expression data from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases, we analyzed the differential expression of CMTM3 in GBM tissues and its impact on the prognosis of GBM patients. Immunohistochemical staining and protein content determination of CMTM3 was performed on GBM and adjacent non-cancerous tissue samples from 11 GBM patients who underwent surgical treatment at the Affiliated Hospital of Guizhou Medical University between November 3, 2022 and March 15, 2023. Additionally, the expression of CMTM3 was validated in GBM cell lines U87, U251, LN229, and the human astrocyte (NHA) cell line using real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot analyses. Stable cell lines with silenced and overexpressed CMTM3 (sh-CMTM3 group and OE-CMTM3 group) were constructed using U251 cells. The effect of CMTM3 expression on cell proliferation was assessed using the Cell Counting Kit-8 (CCK-8) assay. Flow cytometry was employed to examine the impact of CMTM3 expression on the cell cycle. Transwell assays were conducted to evaluate the influence of CMTM3 expression on cell migration. Bioinformatics analysis, Western blotting, NF-κB activation-nuclear translocation assays, and the NF-κB pathway inhibitor pyrrolidine dithiocarbamate ammonium (PDTC) were used to validate the effect of CMTM3 on the NF-κB pathway. Finally, a subcutaneous tumorigenesis assay in nude mice was performed to observe the impact of CMTM3 expression on the in vivo growth of U251 cells. Results:Bioinformatics analysis revealed that CMTM3 is highly expressed in GBM tissues. Patients with a high CMTM3 expression had lower overall survival (OS) and disease-free survival (DFS) rates compared with those with a low CMTM3 expression (with P values of 0.010 and 0.032, respectively). Among the 11 GBM pathological specimens, 10 samples exhibited higher CMTM3 protein expression levels in the cancerous tissue compared with the adjacent non-cancerous tissue. The average CMTM3 protein expression in these samples was 0.44±0.09, significantly higher than that in the adjacent non-cancerous tissues (0.12±0.02, P＜0.001). In one sample, the difference in CMTM3 protein expression between the cancerous and adjacent non-cancerous tissues was not statistically significant ( P=0.750).The RT-qPCR results showed that the mRNA expression level of CMTM3 in NHA cells was 1.0±0.1, whereas in GBM cells U87, LN229, and U251, the levels were 2.1±0.3, 3.4±0.5, and 3.7±0.8, respectively, all significantly higher than that in NHA cells (all P＜0.01). Western blot results demonstrated that the protein expression levels of CMTM3 in GBM cells U87, LN229, and U251 were 1.5±0.2, 1.8±0.2, and 1.9±0.1, respectively, also higher than that in NHA cells (0.7±0.2, all P＜0.01), with the highest level observed in U251 cells. The CCK-8 assay, Flow cytometry, and Transwell migration experiments indicated that cell viability was inhibited in the sh-CMTM3 group, with an increase in the proportion of cells in the G 0/G 1 phase ( P＜0.01) and a decrease in the S phase ( P＜0.01), and the number of migrated cells was 233.6±35.5, lower than that in the sh-NC group ( P＜0.001). Conversely, the OE-CMTM3 group showed enhanced cell viability, a reduction in the proportion of cells in the G 0/G 1 phase ( P＜0.01), and an increase in the S phase ( P＜0.01), and the number of migrated cells was 1212.0±20.8, higher than that in the OE-NC group ( P＜0.001). However, in the OE-CMTM3+PDTC group, cell viability, cell cycle distribution (G 1, S, and G 2 phases), and cell migration numbers showed no significant changes (all P＞0.05). Western blot analysis and NF-κB activation-nuclear translocation assay results indicated that in the sh-CMTM3 group, the p-p65/p65 ratio was 0.51±0.04 and the p-IκBα/IκBα ratio was 0.39±0.03, both lower than those in the sh-NC group (both P＜0.01). The cytoplasmic staining rate was (49.29±1.98)%, higher than that in the sh-NC group ( P＜0.01). In the OE-CMTM3 group, the p-p65/p65 ratio was 2.27±0.10 and the p-IκBα/IκBα ratio was 2.14±0.15, both higher than those in the OE-NC group (both P＜0.01). The cytoplasmic staining rate was (18.96±1.44)%, lower than that in the OE-NC group ( P＜0.01). In the OE-CMTM3+PDTC group, there were no significant differences in the p-p65/p65 ratio, p-IκBα/IκBα ratio, and cytoplasmic staining rate compared with the OE-NC group (all P＞0.05). The subcutaneous tumorigenesis assay in nude mice showed that the tumor volume in the sh-CMTM3 group was (408.9±96.2) mm3, smaller than that in the sh-NC group ( P=0.003). The tumor volume in the OE-CMTM3 group was (1 514.5±251.5) mm3, larger than that in the OE-NC group ( P=0.005). Conclusions:In GBM, CMTM3 is highly expressed and negatively correlated with both OS and DFS of patients. CMTM3 regulates the proliferation and migration abilities of U251 cells through the NF-κB signaling pathway.

Objective:To compare the effect of immediate and delayed post-space preparation on apical sealing ability between 2 root canal obturation techniques.Methods:60 freshly extracted single-rooted human premolars were collected and instrumented by M3-Pro instruments.The specimens were randomly divided into 6 groups and respectively treated by AH-Plus sealer with warm vertical compac-tion(WVC)followed by delayed post-space preparation(PSP)(A1);AH-Plus sealer with WVC followed by immediate PSP(A2);AH-Plus sealer with WVC,control group(A3);iRoot SP sealer with single cone(SC)followed by delayed PSP(B1);iRoot SP sealer with SC followed by immediate PSP(B2);iRoot SP sealer with SC,control group(B3).In group A1,A2,B1 and B2,gutta percha was removed by 1# starter drill and post-space was prepared by 2# finishing drill leaving 5 mm of apical filling.In control groups(A3 and B3),only apical 5 mm of the specimens was obturated.Dye leakage was measured as the linear penetration(LP)of the stain.The SPSS one-way analysis of variance test was used for statistical analysis.Results:The LP(mm)of group A1,A2,A3,B1,B2 and B3 was 3.986±0.500,3.382±0.806,2.178±0.554,3.844±0.877,3.416±0.579 and 1.897±0.217 respectively.Among A1,A2 and A3 groups,P＜0.05.The LP of group A1 was higher than that of group A2(P＜0.05).Among group B1,B2 and B3,P＜0.05,but be-tween group B1 and B2,P＞0.05.Between group A1 and B1,P＞0.05.Between A2 and B2,P＞0.05.Conclusion:Apical sealing is affected by PSP with the 2 root obturation techniques.Delayed PSP may have negative effect on apical sealing compared with immediate PSP,especially in the specimens compacted by AH-Plus sealer with WVC.

Objective To explore the effect of chenodeoxycholic acid(CDCA)on the expression of glucagon-like peptide-1(GLP-1)in the intestine of mice induced by high-fat diet(HFD)through farnesoid X receptor(FXR),and investigate the related mechanism.Methods Forty C57BL/6 mice were divided into control group,HFD group,HFD+CDCA group,HFD+Z-Gug(FXR antagonist)group,and HFD+CDCA+Z-Gug group,with 8 animals in each group.During intervention for 8 weeks,body weight and 24-hour food intake were measured every week.At the 8th week,oral glucose tolerance test(OGTT)and intraperitoneal glucose tolerance test(IPGTT)were conducted.After the mice were sacrificed,the serum levels of GLu,TG,CHO,LDL-C and HDL-C were detected;the expression levels of GLP-1 and FXR in intestinal tissues were detected by immunofluorescence assay;and the mRNA levels of TNF-α,IL-6,IL-1β,Gcg and FXR were detected by RT-qPCR;the serum level of GLP-1 was detected by ELISA,and the proportion of intraepithelial lymphocytes(IELs)subsets and the expression of CD26/DPP4 were detected by flow cytometry.Results Compared with the control group,the HFD group had increased body weight,abnormal serum glucose and lipid metabolism,impaired oral glucose tolerance,and weakened secretion of gastrointestinal hormones(P＜0.05),enhanced FXR expression at mRNA and protein levels,declined Gcg mRNA level and GLP-1 secretion level(P＜0.05),increased mRNA levels of intestinal inflammatory factors TNF-α,IL-6 and IL-1β(P＜0.05),raised proportions of TCRαβ+IELs,TCRαβ+CD8αα+IELs,and TCRαβ+CD8αβ+IELs but reduced proportion of TCRγδ+IELs,and increased total CD26/DPP4 expression in IELs(P＜0.05).Compared with the HFD group,HFD+CDCA treatment resulted in significantly increased body weight,impaired oral glucose tolerance,decreased secretion of gastrointestinal hormones,increased FXR mRNA and protein expression,and decreased Gcg mRNA expression and GLP-1 secretion(P＜0.05);decreased proportions of TCRαβ+IELs,TCRαβ+CD8αα+IELs and TCRααβ+CD8αβ+IELs but increased proportion of TCRγδ+ cells in IELs,and increased expression of total CD26/DPP4 in IELs(P＜0.05),which were significantly improved after Z-Gug intervention(P＜0.05).Conclusion CDCA may inhibit the expression and secretion of GLP-1 in intestinal tissue by activating FXR,and reduce the secretion of GLP-1.At the same time,CDCA may inhibit the expression of related inflammatory factors,regulate the proportions of IELs subsets,up-regulate the expression level of CD26/DPP4,promote the degradation of GLP-1 and aggravate insulin resistance.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
