Objective To investigate the clinical efficacy of Xinxuetong Oral Liquid in the treatment of patients with acute coronary syndrome(ACS).Methods A total of 80 patients with ACS of blood stasis syndrome who were hospitalized in Shunde Hospital of Guangzhou University of Chinese Medicine from January 2023 to September 2023 were randomly divided into the treatment group and control group according to random number table method,40 patients in each group.The patients in the two groups were given conventional western medicine treatment including lifestyle guidance,percutaneous coronary intervention(PCI),and conventional western medicine therapy.Additionally,the treatment group was treated with Xinxuetong Oral Liquid.The course of treatment for the two groups covered eight weeks.Before and after treatment the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome score,blood stasis syndrome score,angina pectoris score,blood lipid indicators,carotid ultrasonography indicators,echocardiography indicators,and serum levels of trimethylamine-N-oxide(TMAO),nitric oxide(NO),endothelin 1(ET-1),interleukin 8(IL-8),serine/threonine-protein kinase 1(AKT-1),and vascular endothelial growth factor A(VEGF-A).After treatment,the efficacy on TCM syndrome efficacy and the safety of the regimen in the two groups were evaluated.Results(1)During the trial,there were two cases of loss to follow-up and one case of withdrawal due to pneumonia,and eventually a total of 77 patients completed the full course of treatment,among which 39 patients were in the treatment group and 38 patients were in the control group.(2)After eight weeks of treatment,the total effective rate of the treatment group was 89.74％(35/39),and that of the control group was 63.16％(24/38).The intergroup comparison(tested by chi-square test)showed that the effective rate of TCM syndrome efficacy in the treatment group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the scores of TCM symptoms such as chest pain,chest distress,symptom aggravation at night,and palpitation in the two groups,as well as the score of gloomy complexion in the treatment group,were significantly decreased compared with those before treatment(P＜0.05 or P＜0.01),and the decrease of scores of chest distress,symptom aggravation at night,and palpitation in the treatment group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(4)After treatment,the blood stasis syndrome score and angina pectoris symptom score of the two groups of patients were significantly decreased compared with those before treatment(P＜0.01),and the decrease in the treatment group was significantly superior to that in the control group(P＜0.01).(5)After treatment,the serum TMAO,ET-1,IL-8,AKT-1,and VEGF-A levels in the two groups were significantly decreased compared with those before treatment(P＜0.01),and the serum NO level was significantly increased compared with that before treatment(P＜0.01).The decrease of serum TMAO,ET-1,IL-8,and AKT-1,VEGF-A levels and the increase of serum NO level in the treatment group were significantly superior to those of the control group(P＜0.05 or P＜0.01).(6)After treatment,the total cholesterol(TCHO)and low-density lipoprotein cholesterol(LDL-C)levels of the two groups(P＜0.01)and the triglyceride(TG)level of the treatment group(P＜0.05)were decreased significantly compared with those before treatment,while the high-density lipoprotein cholesterol(HDL-C)level of the treatment group was increased significantly compared with that before treatment(P＜0.01).No obvious changes of TG and HDL-C levels before and after treatment were shown in the control group(P＞0.05).The comparison of blood lipid indicators after treatment between groups showed that there were no statistically significant differences(P＞0.05).(7)After treatment,the carotid ultrasonography indicators of carotid intima-media thickness(IMT)and Crouse score of the carotid plaque in the two groups were significantly improved compared with those before treatment(P＜0.01).However,there was no statistical significance in the comparison of the two indicators between the two groups after treatment(P＞0.05).(8)The observation of echocardiography indicators showed that only the post-treatment left ventricular diameter(LVd)of the treatment group was significantly larger than that before treatment(P＜0.05),while no obvious changes of the other echocardiography indicators before and after treatment were shown in the two groups(P＞0.05).The comparison between the groups after treatment also showed no statistically significant differences(P＞0.05).(9)During the treatment,no serious drug-induced adverse reactions or drug-related severe cardiovascular events and complications occurred in the two groups.Conclusion The combination of Xinxuetong Oral Liquid with conventional western medicine treatment exerts certain efficacy and safety on improving the clinical symptoms of patients with ACS of blood stasis syndrome,and its therapeutic mechanism may be related to the improvement of blood lipid levels,inflammatory response,and TMAO level.

Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

OBJECTIVE: To observe the clinical significance of translocator proteins (TSPO) gene in the treatment of FLT3-ITD/DNMT3A R882 double-mutated acute myeloid leukemia (AML). METHODS: Seventy-six patients with AML hospitalized in the Department of Hematology of the Affiliated People's Hospital of Ningbo University from June 2018 to June 2020 were selected, including 34 patients with FLT3-ITD mutation, 27 patients with DNMT3A R882 mutation, 15 patients with FLT3-ITD/DNMT3A R882 double mutation, as well as 19 patients with immune thrombocytopenia (ITP) hospitalized during the same period as control group. RNA was routinely extracted from 3 ml bone marrow retained during bone puncture, and TSPO gene expression was detected by transcriptome sequencing (using 2-deltadeltaCt calculation). RESULTS: The expression of TSPO gene in FLT3-ITD group and DNMT3A R882 group at first diagnosis was 2.02±1.04 and 1.85±0.76, respectively, which were both higher than 1.00±0.06 in control group, but the differences were not statistically significant (P=0.671, P=0.821). The expression of TSPO gene in the FLT3-ITD/DNMT3A R882 group was 3.98±1.07, wich was significantly higher than that in the FLT3-ITD group and DNMT3A R882 group, the differences were statistically significant (P=0.032, P=0.021). The expression of TSPO gene in patients who achieved complete response after chemotherapy in the FLT3-ITD/DNMT3A R882 group was 1.19±0.87, which was significantly lower than that at first diagnosis, and the difference was statistically significant (P=0.011). CONCLUSION TSPO gene may be used as an indicator of efficacy in FLT3-ITD /DNMT3A R882 double-mutated AML.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

PURPOSE: This study aimed to elucidate the molecular mechanisms of the anti-pancreatic fibrosis effects of matrine in rats. MATERIALS AND METHODS: Trinitrobenzene sulfonic acid was administrated to rats to establish a pancreatic fibrosis model. Rats were divided into four groups: Control, Sham, Model, and Matrine (n=8). Hematoxylin-eosin staining, Masson staining, and Azan staining were performed to evaluate pancreatic fibrosis. Expression of transforming growth factor-β1 (TGF-β1), α-smooth muscle actin (α-SMA), and collagen I in pancreatic tissues was evaluated by immunohistochemical staining. mRNA and protein levels of TGF-β receptor 1 (TβR1), TβR2, and Smad2 in pancreatic tissues were determined by RT-PCR and Western blot, respectively. RESULTS: In the model group, hyperplasia of glandules around the glandular ducts, mitochondrial swelling of acinous cells, and severe fibrosis were found. Interestingly, in the Matrine group, mitochondrial swelling was only found in a small number of acinous cells, and the fundamental structures of pancreatic tissues were intact. Moreover, pancreatic fibrosis was markedly alleviated. Comparing to the Sham group, expression of α-SMA, TGF-β1, and collagen I was sharply elevated in the Model group (p < 0.05); however, their expressions were much lower in the Matrine group, compared to the Model group (p < 0.05). Compared with the Sham group, mRNA and protein levels of Smad2, TβR1, and TβR2 in the Model group were notably raised (p < 0.05). However, their high expression was significantly downregulated in the Matrine group (p < 0.05). CONCLUSION: Matrine suppressed pancreatic fibrosis by regulating TGF-β/Smad signaling in rats.

Objective: To investigate the impact of FLT3-ITD and DNMT3A R882 double mutations to the prognosis of acute myeloid leukemia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: FLT3-ITD, DNMT3A, C-kit, CEBPA, FLT3-TKD and NPM1 mutations were detected in 206 newly diagnosed AML patients by Sanger sequencing (M(3) and those received FLT3 inhibitor were excluded). Clinical data of AML patients were retrospectively analyzed to compare the prognosis of each gene mutation group. Results: ①Of 206 patients, 104 were male and 102 female with a median age of 38 (3-63) years, including 6 cases of M(0), 24 cases of M(1), 56 cases of M(2), 39 cases of M(4), 63 cases of M(5), 6 cases of M(6) and 12 unclassified cases. ②All 206 patients were divided into four groups according to the mutation gene at the time of diagnosis: FLT3-ITD(+) DNMT3A R882(+) group (group A), FLT3-ITD(+) DNMT3A R882(-) group (group B), FLT3-ITD(-) DNMT3A R882(+) group (group C) and FLT3-ITD(-) DNMT3A R882(-) groups (group D). Gender, leukocyte count at diagnosis, chromosome karyotype, the median age, FAB classification, disease status prior to transplantation, type of donor, conditioning regimen and GVHD were not significantly different between four groups (P>0.05). ③The 2-year cumulative recurrence rate (CIR) of group A was significantly higher than that of other groups [group A (72.2±2.6)%, group B (38.6±0.6)%, group C (36.8±1.6)%, group D (27.8±0.1)%, respectively, P<0.05], while the 2-year overall survival (OS) rate and 2-year leukocyte-free survival (LFS) rate were lower than those of other groups [group A (30.9±13.3)%, (11.3±10.2)%; group B (67.5±7.8)%, (47.9±8.4)%; group C (61.4±12.4)%, (56.8±12.5)%; group D (80.1±3.7)%, (79.7±3.6)%, respectively, P<0.05]. Conclusion: AML patients with FLT3-ITD and DNMT3A R882 double mutations had a very high CIR and low OS, LFS after transplantation.

Tooth development relies on sequential and reciprocal interactions between the epithelial and mesenchymal tissues, and it is continuously regulated by a variety of conserved and specific temporal-spatial signalling pathways. It is well known that suspensions of tooth germ cells can form tooth-like structures after losing the positional information provided by the epithelial and mesenchymal tissues. However, the particular stage in which the tooth germ cells start to form tooth-like structures after losing their positional information remains unclear. In this study, we investigated the reassociation of tooth germ cells suspension from different morphological stages during tooth development and the phosphorylation of Smad2/3 in this process. Four tooth morphological stages were designed in this study. The results showed that tooth germ cells formed odontogenic tissue at embryonic day (E) 14.5, which is referred to as the cap stage, and they formed tooth-like structures at E16.5, which is referred to as the early bell stage, and E18.5, which is referred to as the late bell stage. Moreover, the transforming growth factor-β signalling pathway might play a role in this process.
