OBJECTIVE To optimize the steaming and processing technology of wine-steamed Taxillus chinensis， and to characterize its quality. METHODS Using the content of avicularin， quercitrin， quercetin and appearance traits as evaluation indicators， the analytic hierarchy process （AHP）-entropy weight method was used to determine the weights of each indicator， and the comprehensive scores of those indicators were used as response values. Box-Behnken response surface method was used to investigate the effects of solid-liquid ratio （g/mL）， soaking time， and steaming time on the processing technology of wine-steamed T. chinensis， optimize the best processing technology， and verify it. Fifteen batches of T. chinensis decoction pieces from different origins were used to prepare wine-steamed T. chinensis using the best processing technology， and their qualities were characterized. RESULTS The optimal processing technology for wine-steamed T. chinensis was to take 100 g of T. chinensis decoction pieces， add 20 mL of yellow wine， seal and moisten for 2 h， steam at normal pressure for 1 h， take out and dry at 50 ℃. The surface of wine-steamed T. chinensis prepared by the optimal processing technology was reddish brown or brownish， and its powder was dark brown， with a hard or brittle texture that was easy to break， and had a slight aroma of alcohol， and an astringent taste. Results of microscopic and thin-layer identification for the stem cross-section of wine-steamed T. chinensis were the same as those of raw T. chinensis. The contents of moisture， total ash and acid-insoluble ash were 3.92%-8.75%， 2.27%-5.08%， and 0.19%-0.82%， respectively； the contents of water-soluble extract were 11.28%-18.56%， and the contents of alcohol-soluble extract were 3.36%-8.58%； the contents of avicularin， quercitrin， and quercetin were 0.22-1.64， 0.26-2.45， and 0.01-0.38 mg/g， respectively. CONCLUSIONS This study successfully optimized the processing technology of wine-steamed T. chinensis and preliminarily characterized its quality， which can provide reference for the standardized processing and establishment of quality standards for wine-steamed T. chinensis decoction mail：wyl@sxtcm.edu.cn pieces.

Objective:To compare and explore the diagnostic performance of adding value of transabdominal and transvaginal contrast-enhanced ultrasound (CEUS) to Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of adnexal masses.Methods:A total of 180 adnexal masses with solid components in 175 women were enrolled retrospectively between September 2021 and November 2022. All patients underwent routine Doppler ultrasound examinations and CEUS examinations. Among these masses, 107 masses underwent with transabdominal CEUS, 58 masses underwent with transvaginal CEUS, and 15 masses underwent both transvaginal and transabdominal CEUS. All patients were scheduled for surgery and pathological results served as the reference standard. Routine Doppler ultrasound and CEUS images and video were reviewed by a subspecialty radiologist using Vuebox software. The O-RADS US was downgraded or upgraded according to the CEUS characteristics of the masses. The diagnostic accuracy was assessed using ROC curve analysis. The area under the ROC curve (AUC) was calculated to compare the diagnostic performance of adding value of transabdominal and transvaginal CEUS to O-RADS US.Results:The diagnostic performance of adding transabdominal and transvaginal CEUS to O-RADS US were both significantly higher than of O-RADS US alone (transabdominal CEUS: AUC 0.83 vs 0.76, P=0.018; transvaginal CEUS: AUC 0.92 vs 0.81, P=0.013). Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in the differential diagnosis of adnexal masses ( P=0.047). When the maximal diameter of adnexal masses ≤40 mm, transabdominal combined with O-RADS US presented the lowest diagnostic performance, with an AUC of 0.73. Conclusions:Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in assessing adnexal masses with solid components. When the maximal diameter of adnexal masses ≤40 mm, transvaginal CEUS examination was recommended.

This study was designed to explore the effect of DNA methyltransferase 1(DNMT1)on podocyte apoptosis and inflammatory cytokine release induced by high glucose(HG),and analyze the related molecular mechanisms.Podocyte MPC-5 cells were cultured in vitro and divided into control and HG groups.DNMT1 and SOCS1 were either silenced or overexpressed using small RNA interference technology and liposome transfection technology.The expression levels of DNMT1 and SOCS1 genes were measured using qRT-PCR.Apoptosis was assessed by flow cytometry,while ELISA was employed to determine the levels of inflammatory factors such as tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),interleukin-1β(IL-1β),and monocyte chemoattractant protein-1(MCP-1).Western blot was used to detect the expression of DNMT1,SOCS1 proteins,and the proteins involved in the Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3)signaling pathway.Data showed that HG elevated MPC-5 cell apoptosis rate,the level of inflammatory factors and DNMT1 mRNA expression,and the expression of DNMT1,p-JAK2 and p-STAT3 proteins,while reduced SOCS1 mRNA and protein expression(P＜0.05).Both silencing DNMT1 and overexpressing SOCS1 resulted in reduce of MPC-5 cell apoptosis rate,inflammatory factors level,p-JAK2 and p-STAT3 proteins expression(P＜0.05).Additionally,silencing DNMT1 increased SOCS1 mRNA and protein expressions(P＜0.05).Conversely,silencing SOCS1 counteracted the effects of DNMT1 silencing on MPC-5 cell apoptosis,inflammation,p-JAK2 and p-STAT3 proteins expression.Therefore,silencing DNMT1 expression can reduce the apoptosis and inflammation of podocytes induced by HG,and its mechanism may be related to the inhibition of JAK2/STAT3 signaling pathway activation by upregulating SOCS1 expression.

Objective To observe the alterations in functional complexity of brain regions in autism spectrum disorder(ASD)patients and correlations with the predicted brain age.Methods Open brain resting-state functional MRI(rs-MRI)data of 93 ASD patients and 96 typically developing adolescents(healthy subjects)were downloaded.The functional complexity in brain regions were extracted with self-developed virtual digital brain software,and the alterations in functional complexity of brain regions in ASD patients and correlations with their ages were analyzed.Two networks were prospectively trained with data of 65 ASD patients and 67 healthy subjects as the training set to predict brain age,and the results were evaluated,and the predicting errors were compared using test set,i.e.the other 28 ASD patients and 29 healthy subjects.Results Compared to healthy subjects,on the basis of anatomical automatic labeling(AAL)atlas,ASD patients exhibited significantly reduced functional complexity based on Shannon entropy in the left precuneus,left cuneus and right parahippocampal gyrus.Conversely,functional complexity of ASD patients based on permutation entropy significantly increased in the left cuneus and right cerebellar Crus Ⅱ region.The left hippocampus showed reduced functional complexity based on Pearson correlation coefficient,while the left middle temporal gyrus showed increased functional complexity based on Pearson correlation coefficient.The functional complexity in brain regions of ASD patients were not closely correlated with ages(all|r|＜0.4).According to the trained fully connected network,the predicted brain ages of ASD patients and healthy subjects in test set were all lower than their physiological ages,but no significant difference was found between the prediction errors of ASD patients and healthy subjects(P=0.283).Conclusion Functional complexity changed in some brain region functions in ASD patients.The predicted brain ages of ASD patients based on the obtained fully connected network were on the low side,but not obviously affected by the alterations of functional complexity in brain regions.

OBJECTIVE To optimize extraction technology of couplet medicinals of Astragalus membranaceus-Puerariae lobatae. METHODS With contents of puerarin，daidzin，calycosin-7-O-β-D-glucopyranoside，daidzein，calycosin and formononetin and the yield of dry extract as index，the analytic hierarchy method was used to determine the weight coefficient of each index and calculate the comprehensive score. The effects of solid-liquid ratio， extraction times and extraction time on the comprehensive score were investigated by single factor test. The level of each factor was determined. By multi-index comprehensive scoring method， using comprehensive scores of above 7 indexes as indexes，the extraction technology of couplet medicinals of A. membranaceus-P. lobata was optimized by orthogonal experiment，and the validation tests were conducted. RESULTS The weight coefficient for the contents of puerarin，daidzin，calycosin-7-O-β-D-glucopyranoside，daidzein，calycosin and formononetin and the yield of dry extract were respectively 0.304 7，0.065 2，0.185 8，0.185 8，0.107 8，0.107 8 and 0.042 7. The optimal extraction technology was determined as follows： solid-liquid of 1∶8（g/mL），extracting 3 times and for 1 h each time. RSD of each evaluation index in the validation test results was lower than 3.00% （n＝3）. CONCLUSIONS The optimized extraction technology for A. membranaceus-P. lobata is stable and feasible.

The positive regulation of bone-forming osteoblast activity and the negative feedback regulation of osteoclastic activity are equally important in strategies to achieve successful alveolar bone regeneration. Here, a molybdenum (Mo)-containing bioactive glass ceramic scaffold with solid-strut-packed structures (Mo-scaffold) was printed, and its ability to regulate pro-osteogenic and anti-osteoclastogenic cellular responses was evaluated in vitro and in vivo. We found that extracts derived from Mo-scaffold (Mo-extracts) strongly stimulated osteogenic differentiation of bone marrow mesenchymal stem cells and inhibited differentiation of osteoclast progenitors. The identified comodulatory effect was further demonstrated to arise from Mo ions in the Mo-extract, wherein Mo ions suppressed osteoclastic differentiation by scavenging reactive oxygen species (ROS) and inhibiting mitochondrial biogenesis in osteoclasts. Consistent with the in vitro findings, the Mo-scaffold was found to significantly promote osteoblast-mediated bone formation and inhibit osteoclast-mediated bone resorption throughout the bone healing process, leading to enhanced bone regeneration. In combination with our previous finding that Mo ions participate in material-mediated immunomodulation, this study offers the new insight that Mo ions facilitate bone repair by comodulating the balance between bone formation and resorption. Our findings suggest that Mo ions are multifunctional cellular modulators that can potentially be used in biomaterial design and bone tissue engineering.
