ObjectiveTo evaluate the effects of Tongnaoyin on the blood-brain barrier status and neurological impairment in acute ischemic stroke (AIS) patients with the syndrome of phlegm-stasis blocking collaterals by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). MethodsA total of 63 patients diagnosed with AIS in the Jiangsu Province Hospital of Chinese Medicine from October 2022 to December 2023 were enrolled in this study. According to random number table method,the patients were assigned into a control group (32 cases) and an observation group (31 cases). The control group received conventional Western medical treatment,and the observation group took 200 mL Tongnaoyin after meals,twice a day from day 2 of admission on the basis of the treatment in the control group. After 7 days of treatment,the patients were examined by DCE-MRI. The baseline data for two groups of patients before treatment were compared. The National Institute of Health Stroke Scale (NIHSS) score and modified Rankin Scale (mRS) score were recorded before treatment and after 90 days of treatment for both groups. The rKtrans,rKep,and rVe values were obtained from the region of interest (ROI) of the infarct zone/mirror area and compared between the two groups. ResultsThere was no significant difference in the NIHSS or mRS score between the two groups before treatment. After 90 days of treatment,the NIHSS and mRS scores declined in both groups,and the observation group had lower scores than the control group (P<0.05). After treatment,the rKtrans and rVe in the observation group were lower than those in the control group (P<0.01). ConclusionCompared with conventional Western medical treatment alone,conventional Western medical treatment combined with Tongnaoyin accelerates the repair of the blood-brain barrier in AIS patients,thereby ameliorating neurological impairment after AIS to improve the prognosis.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

As a complex autoimmune disease, rheumatoid arthritis (RA) involves immune microenvironment dysregulation resulting from excessive activation of pyroptosis, which is a crucial factor in disease progression. Based on the theory of ying-wei in traditional Chinese medicine, "ying decline and wei attack" is considered the fundamental pathogenesis of RA. Pyroptosis serves as a microscopic manifestation of this concept, suggesting a potential correlation between "ying decline and wei attack" and pyroptosis nd immune microenvironment dysregulation in RA. Accordingly, treatment principles based on this theory are proposed: in the early stage of the disease, boosting wei to consolidate the exterior, and regulating ying to dispel pathogens; in the middle and late stages, harmonizing ying to remove stagnation, and nourishing its transformational source.

Shengma Gegentang is one of the classic formulas in the Catalogue of Ancient Classic Prescriptions (Second Batch). This study reviewed ancient and modern literature and used literature tracing and bibliometric methods to analyze the historical evolution, efficacy, indications, dosage decoctions, and modern clinical disease spectrum of Shengma Gegentang. The results indicated that the earliest record of Shengma Gegentang can be found in the Taiping Huimin Heji Jufang of the Song dynasty, but its origin can be traced back to the Shaoyao Siwu Jiejitang in the Beiji Qianjin Yaofang of the Tang dynasty. The composition dosage of Shengma Gegentang is 413 g of Cimicifugae Rhizoma, 619.5 g of Puerariae Lobatae Radix, 413 g of Paeoniae Radix Alba, and 413 g of Glycyrrhizae Radix et Rhizoma, which are ground into coarse powder. Each dose is 12.39 g, and the amount of water added is 300 mL. 100 mL of solution is decocted and taken at the right time. The four drugs in the formula play the role of relieving exterior syndrome, penetrating pathogenic factors, and detoxicating together. Its indications are widely involved in internal medicine, pediatrics, surgery, ophthalmology and otorhinolaryngology, obstetrics and gynecology, sexually transmitted diseases, and other diseases, such as measles, sores, acne, spots, surgical gangrene, red eyes, toothache, chancre, and fetal poison. The epidemic diseases treated by Shengma Gegentang are complicated, including rash, pox, macula, numbness, summer diarrhea, dysentery, sha disease, febrile symptoms, spring warmth, winter warmth, and cold pestilence. At the same time, it is a plague prevention formula. Although Shengma Gegentang has a wide range of indications, it cannot be separated from the pathogenic mechanism of evil Qi blocking the muscle surface and heat in the lungs and stomach. The modern clinical disease spectrum of Shengma Gegentang involves the ophthalmology and otorhinolaryngology system, nervous system, pediatric-related diseases and syndromes, skin system, hepatobiliary system, and digestive system. It plays a key role in the treatment of epidemic diseases such as measles, chronic hepatitis B, dysentery, and tetanus.

[Objective] To compare next generation sequencing (NGS) library construction technology between probe hybridization capture and amplicon methods, and analyze the influencing factors of HLA genotyping resolution level and its prospects in clinical applications. [Methods] A total of 207 clinical samples with known typing results and samples from the proficiency testing plan were selected. The conformity rate of HLA genotyping results, allele coverage and typing data analysis indicators were confirmed, and the effects of two library construction methods on the level of HLA genotyping discrimination were compared. [Results] The concordance rate of 207 samples with the feedback results of PT or prior well-characterized HLA genotypes was 100%. Among them, 91 samples were captured using hybridization probe capture method. Compared with the original amplicon method, the hybridization probe capture method can distinguish the alleles of DRB1 and DPB1 that cannot be determined in 13 samples. The allelic imbalance of DRB1, DPA1, and DQB1 loci in 6 samples was resolved. Three samples were found to have missed detection of alleles at the DQA1 and DQB1 loci. [Conclusion] The performance indicators of hybridization probe capture and amplicon performance confirmation meet the requirements of clinical detection of HLA genotyping, which provides an experimental method and basis for clinical application.

ObjectiveTo establish the multi-technique characteristic profiles of Alumen by X-ray diffraction(XRD), Fourier-transform infrared spectroscopy(FTIR) and thermogravimetric-differential thermal analysis(TG-DTA), and to explore the spectral characteristics for rapid identification of Alumen and its potential adulterant, Ammonium alum. MethodsA total of 27 batches of Alumen samples from 8 production regions were collected for preliminary identification based on visual characteristics. The PDF standard cards of XRD were used to differentiate Alumen from A. alum, and the XRD characteristic profiles of Alumen were established, and then the common peaks were screened. Based on hierarchical clustering analysis(HCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA), the characteristic information that could be used for identification of Alumen was selected with variable importance in the projection(VIP) value>1. FTIR characteristic profiles of Alumen were established, and key wavenumbers for identification were screened by HCA and OPLS-DA with VIP value>1. Meanwhile, the thermogravimetric differences between Alumen and A. alum were analyzed by TG-DTA, and the thermogravimetric traits that could be used for identification were screened. ResultsAlumen and A. alum could not be effectively distinguished by traits alone. However, by comparing the PDF standard cards of XRD, 15 batches of Alumen and 12 batches of A. alum could be distinguished. In the XRD profiles, 10 characteristic peaks were confirmed, corresponding to diffraction angles of 14.560°, 24.316°, 12.620°, 32.122°, 17.898°, 34.642°, 27.496°, 46.048°, 40.697° and 21.973°. In the FTIR profiles, 4 wavenumber ranges(399.193-403.050, 1 186.010-1 471.420, 1 801.190-2 620.790, 3 612.020-3 997.710 cm-1) and 12 characteristic wavenumbers(1 428.994, 1 430.922, 1 432.851, 1 434.779, 1 436.708, 1 438.636, 1 440.565, 1 442.493, 1 444.422, 1 446.350, 1 448.279, 1 450.207 cm-1) were identified. In the TG-DTA profiles, there were characteristic decomposition peaks of ammonium ion and mass reduction features near 555.34 ℃ for A. alum. These characteristics could serve as important criteria for distinguishing the authenticity of Alumen. ConclusionXRD, FTIR and TG-DTA can be used to rapidly detect Alumen and A. alum, and combined with the discriminant features selected through chemometrics, the rapid and accurate identification of Alumen and A. alum can be achieved. The research findings provide new approaches for the rapid identification of Alumen.

Hypercoagulable state (HCS) after kidney transplantation is one of the common and serious complications in kidney transplant recipients, which has attracted increasing attention in recent years. HCS refers to the abnormal and excessive activation of blood coagulation function, leading to the increased risk of thrombosis. After kidney transplantation, the combined effects of hemodynamic changes, surgical trauma and severe rejection increase the incidence of HCS, not only raising the risk of thrombosis but also potentially causing graft failure and affecting the postoperative survival rate of patients. This article reviews the influencing factors, clinical manifestations, diagnostic methods and preventive strategies of HCS after kidney transplantation, aiming to provide a theoretical basis for optimizing perioperative management and improving the prognosis of patients.

ObjectiveTo investigate the effect of Danggui Shaoyaosan on ferroptosis in the rat model of non-alcoholic fatty liver disease (NAFLD) and explore the underlying mechanism based on the nuclear factor E2-related factor 2 (Nrf2)/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) signaling pathway. MethodsThe sixty SD rats were randomly grouped as follows: control, model, Yishanfu (0.144 g·kg-1), and low-, medium-, and high-dose (2.44, 4.88, and 9.76 g·kg-1, respectively) Danggui Shaoyaosan. A high-fat diet was used to establish the rat model of NAFLD. After 12 weeks of modeling, rats were treated with corresponding agents for 4 weeks. Then, the body weight and liver weight were measured, and the liver index was calculated. At the same time, serum and liver samples were collected. The levels or activities of total cholesterol (TC), triglycerides (TG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and Fe2+ in the serum and TC, TG, free fatty acids (FFA), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPX), and Fe2+ in the liver were measured. Hematoxylin-eosin staining and oil red O staining were employed to observe the pathological changes in the liver. Immunofluorescence was used to assess the reactive oxygen species (ROS) content in the liver. Mitochondrial morphology was observed by transmission electron microscopy. The protein levels of Nrf2, SLC7A11, GPX4, transferrin receptor 1 (TFR1), and divalent metal transporter 1 (DMT1) in the liver were determined by Western blot. ResultsCompared with the control group, the model group showed increases in the body weight, liver weight, liver index, levels or activities of TC, TG, ALT, AST, and Fe2+ in the serum, levels of TC, TG, FFA, MDA, Fe2+, and ROS in the liver, and protein levels of TFR1 and DMT1 in the liver (P<0.01), and decreases in the activities of SOD, GPX and the protein levels of Nrf2, SLC7A11, and GPX4 in the liver (P<0.05, P<0.01). Meanwhile, the liver tissue in the model group presented steatosis, iron deposition, mitochondrial shrinkage, and blurred or swollen mitochondrial cristae. Compared with the model group, all doses of Danggui Shaoyaosan reduced the body weight, liver weight, liver index, levels or activities of TC, TG, ALT, AST, and Fe2+ in the serum, levels of TC, TG, FFA, MDA, Fe2+, and ROS in the liver, and protein levels of TFR1 and DMT1 in the liver (P<0.01), while increasing the activities of SOD and GPX and the protein levels of Nrf2, SLC7A11, and GPX4 in the liver (P<0.01). Furthermore, Danggui Shaoyaosan alleviated steatosis, iron deposition, and mitochondrial damage in the liver. ConclusionDanggui Shaoyaosan may inhibit lipid peroxidation and ferroptosis by activating the Nrf2/SLC7A11/GPX4 signaling pathway to treat NAFLD.
