Objective: To evaluate the application of blood conservation measures in obstetric patients with different red blood cell transfusion volumes and to assess the impact of different transfusion volumes on postpartum outcomes. Methods: A retrospective investigation was conducted on 448 obstetric patients who received blood transfusions at the Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to December 2022. Patients were divided into four groups (1-2 units group, 3-4 units group, 5-6 units group, and >6 units group) based on the volumes of red blood cells (RBCs) transfused during and within 7 days after delivery. The maternal physiological indicators, pre- and postpartum laboratory test indicators, obstetric complications, application of blood conservation measures, use of blood products, and postpartum outcomes were reviewed. The clinical characteristics, application of blood conservation measures, and their impact on postpartum outcomes were compared among different transfusion groups. Results: There were statistically significant differences in the multivariate logistic analysis of history of previous cesarean section (OR=1.781), eclampsia/pre-eclampsia/(OR=1.972) and postpartum blood loss>1 000 mL（OR=1.699）(P<0.05) among different transfusion groups. In terms of blood conservation measures, the more RBCs transfused, the higher the rate of mothers receiving blood conservation measures such as balloon occlusion, arterial ligation, autologous blood transfusion with a cell saver, and hysterectomy. With the increase in the volume of RBCs transfusion, the demand for fresh frozen plasma（FFP）, cryoprecipitate, and platelet transfusions also increased. The hospitalization days for the four groups of parturients were 6.0 (4.0-9.0), 7.5 (5.0-14.8), 7.0 (4.5-13.0) and 11.0 (9.0-20.5), respectively (P<0.05) and the rates of ICU transfer were 2.0% (5/250), 9.4% (12/128),18.2% (6/33) and 51.4% (19/37), respectively (P<0.05). Both increased significantly with the increase in the volume of RBCs transfusion, and the differences between groups were statistically significant. Conclusion: Parturients who received higher volume of RBCs had multiple risks factors for bleeding before childbirth, had higher postpartum blood loss, and had a higher rate of application of various blood conservation measures. In addition, an increase in the volume of RBCs transfusion may have adverse effects on postpartum recovery.

Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as ¹³¹I,¹⁷⁷Lu, or ¹⁸F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, ¹⁸F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.

ObjectiveTo observe the efficacy of Huoxue Jiedu Formulas （活血解毒方药， HJF） as an adjunctive treatement for patients with binding of stasis and toxin syndrome during the vulnerable period after acute myocardial infarction （AMI） percutaneous coronary intervention （PCI） surgery， and to explore its potential mechanism from the perspective of serum neutrophil extracellular traps （NETs）. MethodsA total of 129 patients with binding of stasis and toxin syndrome within 6 months after PCI for AMI were enrolled and divided into a treatment group （65 cases） and a control group （64 cases） based on patients' willingness to take Chinese herbal medicine. The control group received standard western medical therapy alone， while the treatment group additionally received HJF， one dose daily. Both groups were treated for four weeks. Before and after treatment， TCM syndrome scores were assessed. Seattle angina questionnaire （SAQ） was used to record angina stability and frequency scores， while the short form-36 health survey （SF-36） was employed to assess quality of life across eight dimensions， including physical functioning， role-physical， bodily pain， general health， vitality， social functioning， role-emotional， and mental health. The Pittsburgh sleep quality index （PSQI） was used to evaluate sleep quality， and the patient health questionnaire-15 （PHQ-15） was used to assess psychosomatic symptoms； Duke activity status index （DASI） was used to measure daily physical activity. Serum levels of neutrophil extracellular traps （NET） markers including myeloperoxidase-DNA （MPO-DNA）， neutrophil elastase-DNA （NE-DNA）， and citrullinated histone H3 （CitH3） were measured in 20 patients from the treatment group. ResultsAfter treatment， TCM syndrome score， PSQI score and PHQ-15 score in both groups significantly decreased， while DASI score， angina stability and frequency scores， and all eight dimensions of the SF-36 scale significantly increased （P＜0.05）. Compared to the control group， the treatment group had significantly lower TCM syndrome scores and significantly higher DASI， angina stability and frequency scores （P＜0.05）， as well as higher scores in the SF-36 dimensions of physical functioning， role-physical， social functioning， bodily pain， and vitality （P＜0.05）. After treatment， serum levels of MPO-DNA， CitH3， and NE-DNA in the treatment group were significantly reduced （P＜0.05）. ConclusionHJF combined with conventional therapy can significantly improve angina symptoms， TCM syndrome scores， and psychosomatic conditions in patients with binding of stasis and toxin syndrome during the vulnerable period after AMI. It also enhances quality of life， sleep quality， and daily physical activity. The underlying mechanism may be associated with the inhibition of serum NETs level.

AIM:Using bioinformatics analysis and experiment validation to explore the differential expres-sion genes related to abnormal lipid metabolism in hepatocellular carcinoma(HCC)and the molecular mechanism of pachymaran affecting pyroptosis through squalene epoxidase(SQLE)/nucleotide-binding oligomerization domain-like re-ceptor protein 3(NLRP3)/gasdermin D(GSDMD)signaling pathway.METHODS:(1)The GEO,GSEA,DAVID,STRING and GEPIA databases were employed to screen abnormal lipid metabolism-related differentially expressed genes in HCC.(2)The tumor tissues from HCC patients(n=9)were collected to verify the differential expression of SQLE.(3)The inhibitory effect of pachymaran on the viability of human HCC cell line HepG2 was measured by CCK-8 assay.(4)The HepG2 cells were divided into control group and pachymaran(800 mg/L)group.The cell migration was analyzed by wound-healing assay,and RT-qPCR was used to measure SQLE mRNA expression.(5)The HepG2 cells with overexpres-sion of SQLE(OE-SQLE)were divided into 5 groups as follows:control group,overexpression negative control(OE-NC)group,OE-SQLE group,OE-NC+pachymaran group,and OE-SQLE+pachymaran group.The mRNA and protein expres-sion levels of SQLE and pyroptosis-related factors were determined by RT-qPCR and Western blot.Colorimetric method and ELISA were used to measure lactate dehydrogenase(LDH),interleukin-1β(IL-1β)and IL-18 levels.The necrosis of HepG2 cells was analyzed by flow cytometry.RESULTS:The SQLE gene was screened through bioinformatics analysis,and its mRNA expression was significantly increased in tumor tissues from HCC patients(P＜0.01).In cell experiments,treatment with 800 mg/L pachymaran for 48 h had a significant inhibitory effect on HepG2 cell viability,and the expres-sion of SQLE mRNA was reduced(P＜0.01).After overexpression of SQLE,the mRNA and protein levels of pyroptosis-re-lated factors,necrotic rate,and LDH,IL-1β and IL-18 levels were significantly decreased(P＜0.05).After treatment with pachymaran,the above indicators were significantly increased(P＜0.05).CONCLUSION:The SQLE is abnormal-ly highly expressed in HCC,and pachymaran can affect the growth of HCC cells by activating the NLRP3/GSDMD pyropto-sis pathway through SQLE.

In this paper， we systematically sorted out and verified the name， origin， producing area change， quality， efficacy and processing of Halloysitum Rubrum by consulting materia medica， medical books， prescription books from past dynasties， and modern literature， and combined with the comprehensive analysis of trait identification， hygroscopicity measurement and X-ray diffraction（XRD） detection， in order to provide a basis for understanding the original source of the mineral medicine. The results indicated that Halloysitum Rubrum was first contained in the Shennong Bencaojing， it had been consistently named Chishizhi， there were also aliases such as Chifu， Hongxinshi and Chiyouzhi. The description of Halloysitum Rubrum in ancient materia medica aligns with modern findings， categorizing it under the silicate kaolinite family， specifically polyhydrous kaolinite， with associated minerals mainly being dickite， nacrite， hematite， gibbsite， mica， etc. Historically， the production area of Halloysitum Rubrum was mainly located in the Qinling Mountains， Shandong and Henan， and is now primarily distributed in most parts of China， including Henan， Hubei and other provinces. Quality evaluation in ancient times included descriptions like "fresh and greasy color"， "delicately sticky tongue and lips" and "smooth as fat". Modern materia medica mostly evaluates its quality based on color， luster， texture and hygroscopicity， noting characteristics such as red color， smoothness， delicacy， softness and strong viscosity. Halloysitum Rubrum is sweet， sour and pungent in flavor， warm in nature， non-toxic， and belongs to the heart and large intestine meridians. It acts as an astringent and solidifying agent， particularly useful in the treatment of long-term dysentery and diarrhea， common processing methods include fire calcination， water flying， and vinegar quenching. Comprehensive analysis of the traits， XRD and humidity absorption of different batches of samples showed that the commercially available Halloysitum Rubrum is mainly bright red or brownish red， with a smooth surface like grease， soft and smooth texture， delicate cross-sectional texture， and some have waxy luster and strong water absorption. It is mainly composed of 10 Å（1 Å=0.1 nm） polyhydric kaolinite， and is often accompanied by 7 Å polyhydric kaolinite， nacrite， etc. Genuine products tend to have higher moisture absorption than counterfeit ones， which can be used as a key indicator to distinguish the authenticity. The quality evaluation of Halloysitum Rubrum aligns with historical materia medica， where "fresh color， delicate and greasy lips" could serve as a key feature for its quality evaluation.

Objective To study the influence of implant depth and scanning rod lengths on the accuracy of digital impression for single-tooth implant restoration of the mandibular posterior teeth.Methods Five standard dental cast models with missing right mandibular first molar(46)were prepared with the subgingival implant depths of 0,1,3,5 and 7 mm.ITI RC and ITI RC H11 scanning rods were connected to the replacement body and placed into the seating tract for scanning.The reference data were obtained using a 3D dental scanner,and the experimental data were obtained by 10 scans of each model using a digitized intraoral scanner.Geomagic Wrap 2021 was used to analyze the model data to test the trueness and precision of the models.Results The trueness did not differ significantly among the groups(P>0.05).The implant depth of 1 mm achieved the highest impression precision(66.81±2.45 μm),and the depth of 0 mm resulted in a significantly lower precision(95.60±3.04 μm)than the depth of 1 and 3 mm.Starting from the subgingival depth of 1 mm,the precision of the scan decreased progressively with the increase of the implant depth.At the subgingival implant depth of 5 or 7 mm,the use of an extended rod significantly improved the scan precision.Conclusion For single-tooth implant restoration of the mandibular posterior teeth,the implant depth can substantially affect the accuracy of digital impression,which decreases as the implant depth increases.For a deep implant,the use of a longer scanning rod can improve the scanning accuracy.
