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 investigate the clinical efficacy of integrating pharmacists into family health teams (FHTs) for long-term medication therapeutical management (MTM) in stroke patients, and empirically evaluate the service model. METHODS A pharmacist team, jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University (hereinafter referred to as “our hospital”), developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design, 170 stroke patients discharged from our hospital (July 2022-December 2023) and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group (88 cases) and control group (82 cases) according to random number table. The control group received routine FHTs care (without pharmacist involvement in the team collaboration), while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework, dynamic medication adherence management, medication safety monitoring, a home medication assessment system, and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention, involving medication adherence (adherence rate, adherence score), compliance rates for stroke recurrence risk factors [blood pressure, low-density lipoprotein cholesterol (LDL-C)], and incidence of adverse drug reactions (ADR). RESULTS After 12 months, the trial group exhibited significantly higher medication adherence rates, improved adherence scores, higher compliance rates for blood pressure and LDL-C targets compared to the control group (P<0.05). The incidence of ADR in the trial group (4.55%) was significantly lower than that in the control group (8.11%), though the difference was not statistically significant (P> 0.05). CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence, offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Objective:
To investigate the objective characteristics of tongue manifestation in different stages of damp-heat syndrome in diabetic kidney disease (DKD).
Methods:
A cross-sectional study enrolled 134 patients with DKD G3-5 stages who met the diagnostic criteria for damp-heat syndrome in DKD. The patients were treated at Dongzhimen Hospital, Beijing University of Chinese Medicine, from May 2023 to January 2024. The patients were divided into three groups: DKD G3, DKD G4, and DKD G5 stage, with 53, 33, and 48 patients in each group, respectively. Clinical general data (gender, age, and body mass index) and damp-heat syndrome scores were collected from the patients. The YZAI-02 traditional Chinese medicine (TCM) AI Tongue Image Acquisition Device was used to capture tongue images from these patients. The accompanying AI Open Platform for TCM Tongue Diagnosis of the device was used to analyze and extract tongue manifestation features, including objective data on tongue color, tongue quality, coating color, and coating texture. Clinical data and objective tongue manifestation characteristics were compared among patients with DKD G3-5 based on their DKD damp-heat syndrome status.
Results:
No statistically significant difference in gender or body mass index was observed among the three patient groups. The DKD G3 stage group had the highest age (P<0.05). The DKD G3 stage group had a lower score for symptoms of poor appetite and anorexia(P<0.05) than the DKD G5 group. No statistically significant difference was observed in damp-heat syndrome scores among the three groups. Compared with the DKD G5 stage group, the DKD G3 stage group showed a decreased proportion of pale color at the tip and edges of the tongue (P<0.05). The DKD G4 stage group exhibited an increased proportion of crimson at the root of the tongue, a decreased proportion of thick white tongue coating at the root, a decreased proportion of pale color at the tip and edges of the tongue, an increased hue value (indicating color tone) of the tongue color in the middle, an increased brightness value (indicating color lightness) of the tongue coating color in the middle, and an increased thickness of the tongue coating (P<0.05). No statistically significant difference was observed in other tongue color proportions, color chroma values, body characteristics, coating color proportions, coating color chroma values, and coating texture characteristics among the three groups.
Conclusion
Tongue features differ in different stages of DKD damp-heat syndrome in multiple dimensions, enabling the inference that during the DKD G5 stage, the degree of qi and blood deficiency in the kidneys, heart, lungs, liver, gallbladder, spleen, and stomach is prominent. Dampness is more likely to accumulate in the lower jiao, particularly in the kidneys, whereas heat evil in the spleen and stomach is the most severe. These insights provide novel ideas for the clinical treatment of DKD.

AIM:To evaluate the clinical efficacy of 0.05% cyclosporine eye drops(Ⅱ)combined with sodium hyaluronate eye drops in treating patients with type 2 diabetes mellitus(T2DM)and moderate-to-severe dry eye.METHODS:A total of 120 T2DM patients(120 eyes)with moderate-to-severe dry eye, treated at the endocrinology and ophthalmology departments at the Affiliated Hospital of Xuzhou Medical University from January 2024 to September 2024, were enrolled in the study. The patients were randomly divided into two groups: combination group [0.05% cyclosporine eye drops(Ⅱ)+ sodium hyaluronate eye drops] and control group(sodium hyaluronate eye drops alone), with 60 cases(60 eyes)in each group. Assessments were conducted at baseline and at 1, 2, and 3 mo post-treatment, including the ocular surface disease index(OSDI), non-contact tear meniscus height(NITMH), first non-invasive tear breakup time(NIBUTf), meibomian gland loss score, lipid layer thickness grade, conjunctival hyperemia grade, and corneal fluorescein staining(FL)score. At 3 mo after treatment, changes in tear inflammatory factors were observed, and corneal subbasal nerve plexus(SBN)morphology/density were analyzed using in vivo confocal microscopy(IVCM).RESULTS:At 1, 2, and 3 mo post-treatment, both groups showed statistically significant increases in NITMH and NIBUTf compared to baseline(all P<0.05), with greater improvement observed in the combination group(both P<0.05). OSDI and FL scores significantly decreased from baseline(all P<0.05), with more pronounced reductions in the combination group(both P<0.05). Meibomian gland loss scores showed no significant improvement in either group(all P>0.05). At 3 mo after treatment, tear levels of interleukin 6(IL-6)and matrix metalloproteinase-9(MMP-9)significantly decreased in both groups(all P<0.001), with a greater reduction noted in the combination group(both P<0.001). The combination group displayed increased corneal nerve branch density and nerve fiber density, along with decreased nerve tortuosity and dendritic cell(DC)density compared to baseline(all P<0.001), while the control group did not show significant changes(all P>0.05).CONCLUSION: The combination of 0.05% cyclosporine eye drops(Ⅱ)and sodium hyaluronate eye drops significantly improves clinical outcomes in T2DM patients with moderate-to-severe dry eye. This treatment effectively alleviates ocular surface inflammation, restores corneal nerve morphology and density, and demonstrates a favorable safety profile.

AIM: To explore the risk factors associated with diabetic retinopathy(DR)based on ultra-widefield swept-source optical coherence tomography angiography(UWF-SS-OCTA), and to establish a clinical prediction model.METHODS:A total of 235 patients(235 eyes)with type 2 diabetes mellitus who were treated in the Affiliated Hospital of Xuzhou Medical University from July to November 2024 were selected as the research objects. According to the presence or absence of DR, they were divided into 120 cases(120 eyes)in non-DR group(NDR group)and 115 cases(115 eyes)in non-proliferative DR group(NPDR group). Data on general characteristics, laboratory tests, and OCTA results were collected for both groups. Univariate analysis was employed to identify DR-related risk factors. Logistic regression analysis was conducted to analyze these risk factors and to establish a DR prediction model. The efficacy of the model was evaluated using the receiver operating characteristic(ROC)curve, calibration curve, and decision curve analysis(DCA).RESULTS: The duration of diabetes, fasting blood glucose, blood urea nitrogen(BUN), history of hypertension, and the choroidal vascular index(CVI)were found to be statistically significant in the model(all P<0.05). Specifically, the duration of diabetes, fasting blood glucose, BUN, and history of hypertension were identified as risk factors for DR among diabetic patients, while CVI was recognized as a protective factor. The area under the curve for the model predicting the probability of DR was 0.898(0.859-0.938), with a diagnostic threshold of 0.438. The corresponding sensitivity and specificity were 87.8% and 78.3%, respectively, indicating that the model possesses high predictive value for the occurrence of DR.CONCLUSION: The duration of diabetes, fasting blood glucose, BUN, history of hypertension, and CVI are significantly correlated with DR. The established prediction model demonstrates a substantial screening capability for DR.

ObjectiveTo investigate the mechanism of action of Huangqi Chifengtang (HQCFT) on rats with atherosclerosis (AS) by regulating the gut microbiota and their metabolites. MethodsA rat model of AS was induced through high-fat diet feeding and vitamin D3 injection, and the modeling lasted for 12 weeks. Fifty eight-week-old male SD rats were randomly divided into five groups: A blank group, a model group, a group receiving a low dose of HQCFT at 1.53 g·kg-1 (HQCFT-L group), a group receiving a high dose of HQCFT at 3.06 g·kg-1 (HQCFT-H group), and a group receiving atorvastatin calcium tablets at 1.8 mg·kg-1 (Ato group), with 10 rats in each group. Oral gavage administration started on the day after model establishment, once daily for four weeks. The efficacy of HQCFT was verified using aortic hematoxylin-eosin (HE) staining and determination of lipid levels and hemorrheology. The real-time polymerase chain reaction (Real-time PCR) was used for detecting inflammatory factor levels in the aorta, high-throughput sequencing for analyzing the gut microbiota composition in intestinal contents, targeted metabolomics for detecting short-chain fatty acid (SCFA) levels, and non-targeted metabolomics for identifying metabolomic profiles of intestinal contents. ResultsCompared with that in the blank group, the aortic tissue of rats in the model group showed significant AS lesions, including endothelial damage, inflammatory infiltration, and formation of fibrous plaques and calcified foci. Moreover, serum triacylglycerol (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels were significantly elevated (P<0.05), while high-density lipoprotein cholesterol (HDL-C) levels were significantly reduced (P<0.05). Significant increases were observed in whole blood viscosity, plasma viscosity, and the mRNA expression levels of NOD-like receptor pyrin domain containing 3 (NLRP3), Caspase-1, interleukin (IL)-β, IL-6, and tumor necrosis factor-α (TNF-α) in aortic tissue (P<0.05). Additionally, gut microbiota composition, SCFA levels, and metabolomic profiles were significantly altered. Compared with those in the model group, serum TC, TG, and LDL-C levels, as well as the whole blood viscosity and plasma viscosity, were significantly reduced in all groups treated with HQCFT (P<0.05). Significant decreases were observed in NLRP3 mRNA expression levels in all groups treated with HQCFT, Caspase-1, IL-β, and IL-6 mRNA expression levels in the HQCFT-H group, and TNF-α mRNA expression levels in the HQCFT-L group (P<0.05). HQCFT reversed the increase in the F/B ratio and dialled back the decrease in the relative abundance of Blautia and the increase in that of Desulfovibrio. HQCFT promoted the production of acetic acid, valeric acid, and propionic acid. Non-targeted metabolomics identified 39 differential metabolites, which were mainly enriched in metabolic pathways such as arachidonic acid metabolism and primary bile acid biosynthesis. ConclusionThe mechanism by which HQCFT ameliorates AS injury may be related to the improvement of dyslipidemia and body inflammatory responses by altering gut microbiota composition, promoting SCFA production, and regulating the levels of metabolites in intestinal contents.

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.

ObjectiveTo observe the clinical efficacy of acupuncture combined with bloodletting and cupping in the treatment of chronic spontaneous urticaria(CSU) and to explore its potential mechanisms of action. MethodsSeventy CSU patients were randomly divided into loratadine group and acupuncture + bloodletting group, with 35 patients in each group. The loratadine group received oral loratadine tablets, 10 mg once daily in the evening. The acupuncture + bloodletting group received acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Tianshu (ST 25), Zusanli (ST 36), Sanyinjiao (SP 6), Xuehai (SP 10), Quchi (LI 11), Hegu (LI 4), Taichong (LR 3), Baihui (GV 20), and Shenting (GV 24), once daily,along with bloodletting and cupping at Dazhui (GV 14) and Geshu (BL 17), every other day. Both groups were treated for 4 weeks. The 7-day urticaria activity score(UAS7) was assessed before and after the treatment, and levels of serum immunoglobulin E (IgE), interleukin-4 (IL-4), interleukin-5 (IL-5), eosinophil cationic protein (ECP), plasma tissue factor (TF), activated factor Ⅶ (FⅦa), prothrombin fragment 1+2 (F1+2), D-dimer (D-D) and complement component 5a (C5a) were detected. ResultsA total of 65 patients were included in the final analysis, 32 in the loratadine group and 33 in the acupuncture + bloodletting group. Before treatment, there was no significant difference in UAS7 score, serum IgE, IL-4, IL-5, ECP levels, or plasma TF, FⅦa, F1+2, D-D, C5a levels between groups (P> 0.05). After treatment, both groups showed significant reductions in UAS7 score, serum IgE, IL-4, IL-5, and plasma TF, FⅦa, F1+2, D-D, and C5a levels compared to those before treatment (P<0.01). However, after treatment, there was no significant difference in UAS7 score and serum ECP, IgE, IL-4, IL-5 levels between groups (P>0.05). The acupuncture + bloodletting group showed lower plasma TF, FⅦa, F1+2, D-D and C5a levels compared to the loratadine group (P<0.05 or P<0.01). ConclusionAcupuncture combined with bloodletting and cupping can effectively improve the skin symptoms of CSU patients and reduce the levels of inflammatory factors. The potential mechanism of action may involve the regulation of the coagulation-complement-mast cell activation axis, thereby inhibiting mast cell degranulation.

ObjectiveTo observe the intervention effect of Fufang Kangjiaolv capsules on anxiety-like behaviors in the rat model of chronic restraint stress (CRS) and explore the mechanism underlying the anti-anxiety effect via the microbiota-gut-brain axis. MethodsRats were assigned into blank, model, positive drug (diazepam, 1 mg·kg-1), and low-, medium-, and high-dose (0.75, 1.5, 3 g·kg-1, respectively) Fufang Kangjiaolv capsules groups. After 14 days of administration, the elevated plus maze test, open field test, light and dark box test, and marble burying test were performed. Hematoxylin-eosin staining was employed to observe the pathological changes in the hippocampus and colon of rats, and Nissl staining was conducted to observe the damage of hippocampal neurons. The gut microbiota was analyzed by 16S rRNA gene sequencing. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of zonula occludens-1 (ZO-1) and occludin in the colon of rats. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in the colon, serum, and hippocampus were determined by enzyme-linked immunosorbent assay. Western blot was employed to determine the protein levels of ZO-1, occludin, nuclear factor-κB p65 (NF-κB p65) in the colon tissue and NF-κB p65 and brain-derived neurotrophic factor (BDNF) in the hippocampal tissue. ResultsCompared with the blank group, the model group showed reductions in the time and frequency ratio of rats entering the elevated plus maze, the time and frequency of rats entering the central area of the open field, the time of entering the open box, the times of passing through the light and dark box, and the number of unburied beads (P<0.05, P<0.01). Compared with the model group, Fufang Kangjiaolv capsules ameliorated the anxiety of the model rats to varying degrees, and the high-dose group had the best effect, with increases in the proportions of time and frequency of rats entering the open arm in the elevated plus maze (P<0.05), the number of rats entering the central area in the open field (P<0.05), the time of entering the open box, the times of passing through the light and dark boxes, and the number of unburied beads (P<0.01). Moreover, the high-dose group showed alleviated pathological damage of hippocampal neurons and colon. The results of 16S rRNA gene sequencing showed that the model group had increased relative abundance of Firmicutes, Deferribacterota, Romboutsia, and Phascolarctobacterium, while it had decreased relative abundance of Bavcteroidota and Lactobacillus. The drug administration groups showed increased relative abundance of Bavcteroidota, Bacteroides, norank f norank o Clostridia UCG-014, and Blautia and decreased relative abundance of Firmicutes and Deferribacterota. Compared with the blank group, the model group showed down-regulated protein and mRNA levels of ZO-1 and occludin in the colon (P<0.01), elevated levels of TNF-α, IL-6, and IL-β in the colon, serum, and hippocampus (P<0.01), up-regulated protein level of NF-κB p65 in the colon and hippocampus (P<0.01), and down-regulated protein level of BDNF in the hippocampus (P<0.05). Compared with the model group, high-dose Fufang Kangjiaolv capsules up-regulated the mRNA levels of ZO-1 and occludin in the colon (P<0.01), lowered the levels of TNF-α, IL-6, and IL-β in the colon, serum, and hippocampus (P<0.01), up-regulated the protein levels of ZO-1 (P<0.01) and occludin (P<0.05) in the colon, down-regulated the protein level of NF-κB p65 in the colon and hippocampus (P<0.05), and up-regulated the protein level of BDNF in the hippocampus. ConclusionFufang Kangjiaolv capsules can reduce the anxiety-like behaviors in the rat model of CRS by regulating the gut microbiota disturbance, up-regulating the expression of tight junction proteins in the colon, repairing intestinal mucosal mechanical barrier, and down-regulating NF-κB/BDNF signaling pathway, thereby reducing peripheral and central inflammation. This study proves the hypothesis that Fufang Kangjiaolv capsules play an anti-anxiety role via the microbiota-gut-brain axis, providing a new idea for further research.
