Objective To analyze the impact of tandem mass spectrometry(MS/MS)screening compared to the indanone-fluorescence method(hereinafter referred to as fluorescence analysis)on finance or health insurance in screening newborn genetic metabolic diseases in Shanghai,and provide policy recommendations for MS/MS reimbursement.Methods A budget impact analysis model was constructed using Microsoft Excel 2019,with a study period of 3 years(2025?2027).Newborns of 2025 to 2027 were predicted based on the birth data of newborns in Shanghai and the average decrease of newborns in Shanghai.Clinical screening data and cost data were derived from relevant statistical websites,literature,and hospital survey data.Additionally,consultations with experts were conducted to understand national and Shanghai-specific screening and reimbursement policies.Among these,the fluorescence-based analysis method is primarily used for screening phenylketonuria,while MS/MS can be used for screening a variety of newborn genetic and metabolic disorders.So we separately calculated the impact of MS/MS screening compared to the fluorescence-based method on Shanghai's fiscal budget and health insurance fund.Results The budget impact analysis on fiscal expenditures indicates that from 2025 to 2027,the fiscal expenditures for fluorescence analysis will be 1.58 million,1.48 million and 1.39 million yuan,respectively.In contrast,MS/MS fiscal expenditures will be 22.75 million,21.37 million,and 20.06 million yuan,respectively;compared with fluorescence analysis,the increased fiscal expenditures for MS/MS will be 21.18 million,19.88 million,and 18.67 million yuan,respectively,showing a decreasing trend annually.The budget impact on health insurance funds shows that from 2025 to 2027,the expenditures for fluorescence analysis will be 1.11 million,1.04 million and 0.97 million yuan,respectively;MS/MS health insurance fund expenditures will be 15.93 million,14.96 million and 14.04 million yuan,respectively.Compared with fluorescence analysis,the additional health insurance fund expenditures for MS/MS will be 14.82 million,13.92 million and 13.07 million yuan,respectively,also showing a decreasing trend annually.Policy-wise,the costs for tandem mass spectrometry screening are typically covered by fiscal payments or out-of-pocket by patients,with commercial insurance,charitable foundations,and other organizations serving as supplementary sources of funding.Conclusion The overall cost of expanding newborn screening for genetic metabolic diseases in Shanghai is controllable.To unify the payment standards and facilitate centralized management,it is recommended that the costs for tandem mass spectrometry screening in Shanghai be covered by government funding.

Aim To investigate the effect of icariin(ICA)on chronic ulcerative colitis(UC)in mice.Methods Male SPF-grade C57BL/6J mice were ran-domly divided into the control group,model group,low-dose ICA group,and high-dose ICA group.Except for the control group,the rest of the mice were established as chronic UC models.Expressions of tight junction proteins,inflammatory factors,fibrosis markers,macro-phage markers,and MAPK signaling pathways in the colonic epithelium of each group were determined by Western blot,qPCR,immunohistochemistry;the degree of intestinal damage and fibrosis was detected by HE and Masson staining;the co-localization of different macrophage markers with related factors was examined by immunofluorescence.Results Treatment of ICA significantly improved the general condition of chronic UC mice,decreased the infiltration of M1-type macro-phages and the secretion of pro-inflammatory factors,inhibited the MAPK signaling pathway,reduced the co-localization expression of M1-type macrophages with the MAPK signaling pathway,and downregulated the infiltration of M2-type macrophages and the secretion of pro-fibrotic factors in the colon.Conclusion ICA mitigates the inflammatory damage and fibrosis of colon in chronic UC mice.

The changes of serum cyclophilin A (CyPA), its receptor CD147 and the downstream signaling pathway during the process of cardiac hypertrophy remain unknown. The present study aims to investigate the relationships between CyPA-CD147-ERK1/2-cyclin D2 signaling pathway and the development of cardiac hypertrophy. Left ventricular hypertrophy was prepared by 2-kidney, 2-clip in Sprague-Dawley rats and observed for 1 week, 4 and 8 weeks. Left ventricular hypertrophy was evaluated by ratio of left ventricular heart weight to body weight (LVW/BW) and cardiomyocyte cross sectional area (CSA). CyPA levels in serum were determined with a rat CyPA ELISA kit. Expressions of CyPA, CD147, phospho-ERK1/2 and cyclin D2 in left ventricular myocytes were determined by Western blot and immunostaining. Compared with sham groups, systolic blood pressure reached hypertensive levels at 4 weeks in 2K2C groups. LVW/BW and CSA in 2K2C groups were significantly increased at 4 and 8 weeks after clipping. ELISA results indicated a prominent increase in serum CyPA level associated with the degree of left ventricular hypertrophy. Western blot revealed that the expressions of CyPA, CD147, phospho-ERK1/2 and cyclin D2 in left ventricular tissues were also remarkably increased as the cardiac hypertrophy developed. The results of the present study demonstrates that serum CyPA and CyPA-CD147-ERK1/2-cyclin D2 signaling pathway in ventricular tissues are time-dependently upregulated and activated with the process of left ventricular hypertrophy. These data suggest that CyPA-CD147 signaling cascade might play a role in the pathogenesis of left ventricular hypertrophy, and CyPA might be a prognosticator of the degree of left ventricular hypertrophy.

OBJECTIVETo explore the effect of Salvia miltiorrhiza monomer IH764-3 on apoptosis in hydrogen peroxide (H2O2)-stimulated hepatic stellate cells (HSCs).

METHODSHSCs were cultured in medium with different IH764-3 doses (10 mg/L, 20 mg/L, 30 mg/L, 40 mg/L) and without IH764-3. Direct cell count, 3H-thymidine incorporation, Annexin-V/Propidium Iodide double-labeled flow cytometry, TUNEL and transmission electron microscopy were employed to estimate the influence of IH764-3 on proliferation and apoptosis of HSCs. The expression of extracellular signal-regulated kinase 1 (ERK1) mRNA and protein in HSCs were detected using RT-PCR and Western blot respectively.

RESULTSIt was showed that H2O2 could promote HSC proliferation. In contrast, IH764-3 at concentrations of 10 mg/L, 20 mg/L, 30 mg/L and 40 mg/L inhibited its proliferation. The inhibition rates were 7.13%, 28.36%, 53.80% and 73.10% (P < 0.01). And the inhibition rates of IH764-3 at concentrations of 30 mg/L at 12 h, 24 h and 48 h were 22.24%, 40.51% and 61.65%. Furthermore, IH764-3 could also induce the HSC apoptosis in dose-dependent an dtime-dependent manners (P < 0.01). In addition, after exposed of HSCs to IH764-3 for 24 h, ERK production decreased and ERK1 mRNA was down-regulated earlier about 2 h after exposure to IH764-3.

CONCLUSIONIH764-3 may inhibit the proliferation and induce apoptosis of HSCs in both dose-dependent and time-dependent manners, which may be related to down-regulation of ERK expression.

OBJECTIVETo investigate the role of focal adhesion kinase (FAK) in adhesion and migration of hepatic stellate cells (HSC).

METHODSTwo recombinant plasmids expressing short hairpin RNAs (shRNAs) targeting FAK were constructed and one plasmid substantially suppressing FAK expression in HSC was selected. Real-time PCR and Western blot were used to detect the knockdown effects of FAK gene. After 48-hour treatment with FAK shRNA, toluidine blue colorimetric assay was used to detect the cell adhesion. Wound-healing assay and improved Boyden double-chamber were used to detect the cell migration induced by FN.

RESULTSThe recombinant plasmid expressing FAK shRNA was successfully constructed and transfected into HSC. Compared with the controls, the expression of FAK mRNA and protein in HSC treated with FAK shRNA was markedly down-regulated by 76.82% and 72.53%, respectively. The expression of p-FAK (Tyr397) protein was also decreased by 62.71% 48 h posttransfection. The adhesion of HSC was inhibited by 58.69% at 48 h after shRNA transfection. FAK gene silencing could also dramatically inhibit FN-stimulated HSC migration, and the cell migration distance and the cell number of crossing membrane were decreased by 58.27% and 83.70%, respectively.

CONCLUSIONSFAK gene silencing suppresses adhesion and migration of HSC, and FAK may be a potential target for novel anti-fibrosis therapies.
