ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

OBJECTIVE: To investigate the therapeutic potential of octaarginine (R8)-modified essential oil from Fructus Alpiniae zerumbet (EOFAZ) lipid microspheres (EOFAZ@^R8LM) for cardiovascular therapy. METHODS: EOFAZ@^R8LM was developed by leveraging the volatilization of EOFAZ and integrating it with the oil phase of LM, followed by surface modification with cell-penetrating peptide R8 to target the site of vascular endothelial injury. The therapeutic effects of this formulation in alleviating lipopolysaccharide-induced vascular endothelial inflammation were evaluated by assessing mitochondrial membrane potential (MMP), intracellular reactive oxygen species (ROS) levels, as well as inflammatory factors interleukin-6 (IL-6) and interleukin-1β (IL-1β) levels. RESULTS: EOFAZ@^R8LM effectively delivered EOFAZ to the site of injury and specifically targeted the mitochondria in vascular endothelial cells, thereby ameliorating mitochondrial dysfunction through regulation of MMP and reduction of intracellular ROS levels. Moreover, it attenuated the expression levels of IL-6 and IL-1β, exerting protective effects on the vascular endothelium. CONCLUSION Our findings highlight the significant therapeutic potential of EOFAZ@^R8LM in cardiovascular therapy, providing valuable insights for developing novel dosage forms utilizing EOFAZ for effective treatment against cardiovascular diseases.

Cholesterol (CH) plays a crucial role in enhancing the membrane stability of drug delivery systems (DDS). However, its association with conditions such as hyperlipidemia often leads to criticism, overshadowing its influence on the biological effects of formulations. In this study, we reevaluated the delivery effect of CH using widely applied lipid microspheres (LM) as a model DDS. We conducted comprehensive investigations into the impact of CH on the distribution, cell uptake, and protein corona (PC) of LM at sites of cardiovascular inflammatory injury. The results demonstrated that moderate CH promoted the accumulation of LM at inflamed cardiac and vascular sites without exacerbating damage while partially mitigating pathological damage. Then, the slow cellular uptake rate observed for CH@LM contributed to a prolonged duration of drug efficacy. Network pharmacology and molecular docking analyses revealed that CH depended on LM and exerted its biological effects by modulating peroxisome proliferator-activated receptor gamma (PPAR-γ) expression in vascular endothelial cells and estrogen receptor alpha (ERα) protein levels in myocardial cells, thereby enhancing LM uptake at cardiovascular inflammation sites. Proteomics analysis unveiled a serum adsorption pattern for CH@LM under inflammatory conditions showing significant adsorption with CH metabolism-related apolipoprotein family members such as apolipoprotein A-V (Apoa5); this may be a major contributing factor to their prolonged circulation in vivo and explains why CH enhances the distribution of LM at cardiovascular inflammatory injury sites. It should be noted that changes in cell types and physiological environments can also influence the biological behavior of formulations. The findings enhance the conceptualization of CH and LM delivery, providing novel strategies for investigating prescription factors' bioactivity.

Objective To construct an intelligent segmentation and T-stage diagnostic model for esophageal cancer based on the DAEUnet and ConvNeXt networks using transfer learning.Methods Dicom raw data from 126 patients diagnosed with esophageal cancer between January 2018 and April 2022 were collected,including 100 cases from Department of Thoracic Surgery at the First Affiliated Hospital of Army Medical University and 26 cases from the Department of Thoracic Surgery at Shanxi Cancer Hospital.After data augmentation,a total of 60 275 images were obtained.The DAEUnet esophageal cancer intelligent segmentation network was built,and on this basis,3 classification networks,ConvNeXt,Swin Transformer,and ResNet were constructed for T-stage diagnosis of esophageal cancer.Results The Dice similarity coefficient(DSC)for esophageal cancer intelligent segmentation using the DAEUnet network was 0.82,and the DSC value of the esophagus,aorta,normal esophagus,mediastinal lymph nodes,and heart was 72.4％,87.5％,79.3％,60.5％ and 96.8％,respectively.Among the 3 T-stage diagnosis models for esophageal cancer,the ConvNeXt model performed the best,with a precision value for T1～T4 stages of 0.65,0.727,0.889 and 0.92,respectively,and an AUC value of 0.892,which were superior to the ResNet and Swin Transformer networks.Conclusion The proposed DAEUnet and ConvNeXt-based intelligent segmentation and T-stage diagnosis model for esophageal cancer improves T-stage accuracy and treatment efficiency.

Objective To analyze the relationship between serum nuclear factor E2-related factor 2(NRF2),heme oxygenase-1(HO-1)levels and disease activity and prognosis in patients with lupus nephritis(LN).Methods A total of 188 LN patients who visited the hospital from March 2020 to January 2022 were selected as the case group,and were divided into a stable group(60 cases,＜10 points)and an active group(128 cases,≥ 10 points)according to the Systemic Lupus Erythematosus Disease Activity Index(SLEDAI)score.Another 160 healthy subjects were selected as control group.The differences of serum NRF2 and HO-1 levels between case group and control group were compared,the serum NRF2 and HO-1 levels and renal func-tion indexes[glomerular filtration rate(GFR),serum creatinine(Scr),urea nitrogen(BUN)]were compared between stable group and active group,and the correlation between serum NRF2 and HO-1 levels and disease activity and renal function in LN patients was analyzed by Pearson.After 2 years of follow-up,LN patients were divided into good prognosis group(117 cases)and poor prognosis group(71 cases)according to the oc-currence of renal-related endpoint events.Serum NRF2,HO-1 levels and other clinical data were compared be-tween two groups,and the prognostic factors of LN patients were analyzed by multivariate Logistic regression model.A nomogram prediction model was constructed and verified based on the influencing factors.Results The levels of serum NRF2 and HO-1 in case group were lower than those in control group(P＜0.05).NRF2,HO-1 and GFR levels in active group were lower than those in stable group,and Scr,BUN and SLEDAI scores were higher than those in the stable group(P＜0.05).Pearson correlation analysis showed that,serum NRF2 and HO-1 levels were negatively correlated with SLEDAI score,Scr and BUN in LN pa-tients(r＜0,P＜0.05),and positively correlated with GFR(r＞0,P＜0.05).The NRF2,HO-1 and GFR in poor prognosis group were lower than those in good prognosis group,and the proportion of CKD stage 3-4 and SLEDAI score in poor prognosis group were higher than those in good prognosis group(P＜0.05).Multi-variate Logistic regression model showed that CKD stage 3-4 and the increase of SLEDAI score were inde-pendent risk factors for poor prognosis of LN patients(P＜0.05),while the increase of NRF2,HO-1 and GFR levels were independent protective factors(P＜0.05).The nomogram prediction model based on influen-cing factors had a good predictive value for the prognosis of LN patients.Conclusion NRF2 and HO-1 are lowly expressed in the serum of LN patients,and the two are closely related to their disease activity and renal function.The high expression of NRF2 and HO-1 will reduce the risk of renal-related endpoint events in LN patients.The nomogram prediction model based on influencing factors has a good predictive value for the prognosis of LN patients.

Small for gestational age (SGA) infants are more likely to experience neurocognitive impairments compared to appropriate for gestational age (AGA) infants. This paper reviews recent research on the neurocognitive development of SGA children. SGA can lead to a "brain-sparing effect" due to growth restriction, which may affect cerebral blood flow and brain structure. However, this does not guarantee normal brain development. Restrictive blood flow can result in changes in brain structure, such as reduced total white matter and gray matter volume in various brain regions, including the cerebral cortex, hippocampus and cerebellum, ultimately leading to decreased head circumference. SGA children also exhibit lower scores in all neurocognitive domains, including intelligence, attention, memory, and executive function. This may result in poor academic performance and an increased risk of social, behavioral, and neurological problems, such as cerebral palsy, epilepsy, visual and hearing impairments, as well as comorbidities like attention deficit hyperactivity disorder(ADHD), autism spectrum disorder(ASD), anxiety, depression, and schizophrenia. Several risk factors for SGA-related neurocognitive impairments have been identified, including gestational hypertension, abnormal gestational weight, smoking, and catch-up growth. Studies have shown that the best interventions to improve cognitive dysplasia include nutrient supplementation, continued breastfeeding, high-quality education, and appropriate early intervention (responsive parenting) are effective in improving cognitive outcomes for SGA children.

ObjectiveTo explore the effect and possible molecular mechanism of Qinghua Yichang Formula （清化益肠方， QYF） in treating acute radiation-induced intestinal injury mice via NOD-like receptor thermal protein domain associated protein 3 （NLRP3）. MethodsSixty C57BL/6J mice were randomly divided into control group， model group， pre-modeling medication group， post-modeling medication group， inhibitor group， and QYF plus inhibitor group， with 10 mice in each group.Except for the control group， the other five groups were irradiated with a single full dose to establish the acute radiation-induced intestinal injury mice model. The pre-modeling medication group and the QYF plus inhibitor group were continuously given 4 g/ml of QYF decoction by gavage before modeling， 0.2 ml each time， once a day for 7 days. The post-modeling medication group， pre-modeling medication group and QYF plus inhibitor group were given 4 g/ml of QYF decoction for 14 days after modeling. The control group， model group and inhibitor group were given 0.2 ml of normal saline once a day for 14 consecutive days. Two hours after irradiation， the inhibitor group and the QYF plus inhibitor group were given an intraperitoneal injection of 0.2 ml of the NLRP3 inhibitor MCC950 （concentration： 10 mg/kg）， once every two days. To observe the pathological changes in intestinal tissues， hematoxylin-eosin （HE） staining was used. Western blotting and RT-qPCR were used to detect the protein and mRNA expression levels of NLRP3 in intestinal tissues. Immunohistochemistry was used to detect the expression level of NLRP3， Caspase-1 and GSDMD in intestinal tissues. The proportion of CD4⁺ and CD8⁺ T cells in the spleens of mice were detected by flow cytometry. ELISA was used to determine the levels of IFN-γ， IL-18， and IL-1β in mice serum. ResultsHE staining showed no lesions in the intestinal tissue of mice in the control group. The mice in the model group had shortened intestinal villi， thinned mucosal layers， multifocal mucosal necrosis in the lamina propria， and local neutrophil infiltration. The pathological damage of intestinal tissue of mice in each medication group was improved to varied degrees， among which the QYF plus inhibitor group showed most obvious improvement. Compared to those in the control group， the protein and mRNA expression levels of NLRP3 in the intestinal tissue of mice in the model group significantly increased， with higher NLRP3， Caspase-1， and GSDMD protein expression in the intestinal tissue， increased proportion of CD4⁺ T cells in spleen， decreased proportion of CD8⁺ T cells， and increased levels of IFN-γ， IL-18 and IL-1β in serum （P＜0.05）. Compared to those in the model group， the above indicators in the other medication groups were all improved （P＜0.05）.The NLRP3， Caspase-1， and GSDMD proteins in the pre-modeling medication group were lower than those in the post-modeling medication group （P＜0.05）； and the NLRP3 mRNA level in the QYF plus inhibitor group was lower than that in the inhibitor group （P＜0.05）. ConclusionQYF may play a role in preventing and treating acute radiation-induced intestinal injury by inhibiting the expression of NLRP3.

Objective:To explore the effect of personalized nutritional support based on nutritional risk screening on nutritional status and prognosis of patients with inflammatory bowel disease.Methods:A total of 100 patients with inflammatory bowel disease admitted to the Department of Gastroenterology, The First Affiliated Hospital of Wenzhou Medical University from January 2021 to September 2022 were selected as the study objects, and were divided into control group and observation group according to the random number method. NRS 2002 nutritional risk screening was performed on all patients. The control group was given routine nursing and nutritional support. On this basis, the observation group received patient-centered personalized nutrition support program shared by doctors and patients. The nutritional status, inflammatory indicators and prognosis of the two groups were compared and observed at admission, discharge, 1 month after discharge, and 3 months after discharge.Results:From admission to 3 months after discharge, albumin, prealbumin, nitrogen balance, triceps skinfold thickness in the two groups were significantly increased ( F = 8.43, 14.32, 10.27, 23.41, 7.66, 8.91, 6.84, 8.90, P < 0.05), while the malnutrition inflammation score was significantly decreased ( F = 4.84, 7.42, P < 0.05). Albumin, prealbumin, nitrogen balance, triceps skinfold thickness in the observation group were significantly higher than those in the control group at 3 months after discharge ( t = 7.95, 17.43, 6.55, 6.72, P < 0.001), and the malnutrition inflammation score was significantly lower than that of the control group ( t = 6.95, P < 0.001). As treatment progressed, the levels of C-reactive protein and fecal calprotectin gradually decreased and the erythrocyte sedimentation rate slowed down in both groups compared with the admission, with statistical significance ( F = 9.03, 11.28, 18.37, 19.20, 32.42, 28.88, P < 0.001). The levels of C-reactive protein and fecal calprotectin and erythrocyte sedimentation rate in the observation group were significantly lower than those in the control group 3 months after discharge ( t = 8.29, 7.99, 10.34, P < 0.001). Patients in the observation group had good compliance with the formulated diet plan, and no related rejection events occurred. The readmission rate of patients in the observation group was significantly lower than that of the control group ( χ2 = 10.18, P < 0.05). Conclusion:Individualized nutrition support programs based on nutritional risk screening can help improve the nutritional status and disease status of patients with inflammatory bowel disease.
