ObjectiveTo investigate the effect of Naoqingtong decoction (NQT) on the kidney damage and the inflammatory factors NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain (ASC), cysteinyl aspartate-specific proteinase-1 (Caspase-1), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in spontaneously hypertensive rats (SHRs). MethodsTwenty-four SHRs were randomized into a model group, a low-dose (12.9 g·kg-1·d-1) NQT (NQT-L) group, a high-dose (25.8 g·kg-1·d-1) NQT group (NQT-H), and a captopril (CTP, 20 mg·kg-1·d-1) group, with 6 rats in each group. In addition, 6 homozygous male Wistar-Kyoto rats were used as the control group. The control and model groups were administrated with the same amount of normal saline by gavage for 8 weeks. General behaviors of rats were observed during the intervention period, and the blood pressure was measured periodically. At the end of intervention, the body mass was weighed, and both kidneys were collected and weighed for the calculation of the renal index. Hematoxylin-eosin staining was performed to observe the pathological changes in the kidney tissue. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the expression levels of NLRP3, ASC, Caspase-1, IL-6, and TNF-α in the kidney tissue. ResultsDuring the experiment period, the control group had normal mental status, food intake, and activity, while the model group showed thinning of hair, loss of luster, reduced activity, loss of appetite, fecal adhesion, and irritability, and some of the skin had scratches or blood scabs. The above symptoms were alleviated to different degrees after 8 weeks of NQT administration. An intelligent non-invasive sphygmomanometer was used to measure the tail artery pressure of rats, which showed that the systolic and diastolic blood pressure of rats in the model group was higher than that in the control group (P<0.01). Compared with the model group, drug interventions lowered the systolic and diastolic blood pressure (P<0.05, P<0.01). Compared with the control group, the model group showed severe pathological damage in the kidney tissue, which was alleviated in each drug intervention group. Compared with the control group, the model group showed up-regulated expression levels of NLRP3, ASC, Caspase-1, IL-6, and TNF-α in the kidney tissue (P<0.05, P<0.01). Compared with the model group, the drug intervention groups showed down-regulated expression levels of NLRP3, ASC, Caspase-1, IL-6, and TNF-α in the kidney tissue (P<0.05, P<0.01). ConclusionNQT can lower the blood pressure in SHRs by inhibiting the activation of NLRP3 inflammasomes, suppressing renal inflammation, and ameliorating hypertensive kidney damage.

Polymyxin is an essential antibiotic for treating multidrug-resistant Gram-negative bacterial infections; however, its significant nephrotoxicity greatly limits its clinical application. To enhance its safety and improve patient outcomes, the study of novel biomarkers for the early prediction of polymyxin-associated acute kidney injury is critically important. Novel biomarkers, such as cystatin C, kidney injury molecule-1, neutrophil gelatinase-associated lipocalin, N-acetyl-β-glucosaminidase, β2- microglobulin, have shown obvious advantages in the early prediction of polymyxin-associated acute kidney injury. Compared to traditional biomarkers, these biomarkers can provide sensitive and specific diagnostic information in the early stages of kidney injury, helping to optimize individualized treatment plans and reduce clinical risks. However, the high cost of detection and complex operation still limit their clinical promotion. Future research should focus on optimizing the detection technology of new biomarkers, simplifying the operation process and reducing costs, while conducting multi-center, large-scale randomized controlled trials to systematically evaluate the sensitivity and specificity of various novel biomarkers, in order to promote their application in the field of prediction of renal injury in clinical practice.

ObjectiveTo investigate the effects of Xijiao Dihuangtang (XJDHT) on mice with sepsis and cellular models of sepsis and explore its molecular mechanism in alleviating sepsis-induced inflammatory responses via regulating pyruvate kinase M2 (PKM2)-mediated one-carbon metabolism pathway. MethodsForty C57BL/6N mice were randomly divided into four groups: normal group, model group, low-dose XJDHT group (7.7 g·kg-1), and high-dose XJDHT group (15.4 g·kg-1). After one week of continuous gavage, sepsis was induced using cecal ligation and puncture (CLP) in groups except the normal group. 24 h after the surgery, mortality rates in all groups were recorded, and serum cytokines were measured by enzyme linked immunosorbent assay (ELISA). Lung histopathology was examined by hematoxylin-eosin (HE) staining. During the in vitro experiment, the human monocytic leukemia cell line (THP-1) was exposed to various concentrations of XJDHT and treated with lipopolysaccharide (LPS) at a final concentration of 2 mg·L-1 for 24 h. Cell apoptosis was detected using terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Protein levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), B-cell lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax) were measured by Western blot. Transcriptome sequencing was performed to analyze differentially expressed genes in all groups and conduct gene ontology (GO) enrichment. Key genes in the one-carbon metabolism pathway, including pyruvate kinase M2 (PKM2), 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR), and phosphoglycerate dehydrogenase (PHGDH), were verified by Western blot. A PKM2 inhibition model was established using shikonin for further protein expression analysis. ResultsAnimal experiments showed that compared with the normal group, the model group exhibited significantly elevated body temperature and lung pathology (P<0.01) and increased serum TNF-α and IL-1β levels (P<0.01). High-dose XJDHT reduced body temperature and lung tissue damage (P<0.01) and significantly decreased serum TNF-α and IL-1β levels (P<0.01). Low-dose XJDHT treatment showed no significant temperature change (P<0.01) but reduced serum TNF-α and IL-1β levels (P<0.01). Transcriptome sequencing and Western blot revealed significant differences in the expression of TNF-α, IL-1β, and one-carbon metabolism genes (PKM2, MTR, and PHGDH) (P<0.01). Cell experiments demonstrated that compared to the normal group, the model group showed elevated protein expressions of TNF-α and IL-1β in THP-1 cells (P<0.01), decreased Bcl-2/Bax ratio, and increased apoptosis (P<0.01). Transcriptome sequencing and Western blot revealed significant differences in the expression of TNF-α, IL-1β, and one-carbon metabolism genes (PKM2, MTR, and PHGDH) (P<0.01). Compared to the model group, high-dose XJDHT significantly increased Bax/Bcl-2 ratio and PHGDH protein expression (P<0.01) and effectively reduced cell apoptosis (P<0.01) while down-regulating protein expressions of TNF-α, IL-1β, PKM2, and MTR (P<0.01). Low-dose XJDHT moderately increased Bax/Bcl-2 ratio and PHGDH protein expression (P<0.05), reduced apoptosis (P<0.05), and decreased IL-1β and MTR protein levels (P<0.05, P<0.01), but there were no significant changes in TNF-α and PKM2 expression. After PKM2 inhibition by shikonin in THP-1 cells, the expression of protein related to one-carbon metabolism was detected. Compared with the blank group, the LPS-induced model group showed significantly upregulated PKM2 and MTR protein expression (P<0.01) and downregulated PHGDH expression (P<0.01). Compared with the model group, shikonin treatment significantly reduced PKM2 expression (P<0.05), increased PHGDH expression (P<0.01), and decreased MTR expression (P<0.05). ConclusionXJDHT can inhibit the release of inflammatory factors in sepsis, and its mechanism is related to the intervention of the PKM2-regulated one-carbon metabolism pathway in macrophages.

Systemic juvenile arthritis disease activity score(sJADAS)was used to evaluate the efficacy of the treatment. Statistical analysis was performed by repeated measurements using general linear models.Results:Among the 10 children(4 males and 6 females)with refractory sJIA,the average age of onset was(7.5±3.3)years. Seven patients were complicated with macrophage activation syndrome at an early stage of disease.The average course of disease was(4.4±1.7)years,and the longest course of disease was 8.3 years. Before the application of thalidomide,all the 10 children experienced relapses(ranging from 2 to 10 times). The indices of 10 children treated with thalidomide at 6 months and 12 months were compared with those before treatment. Peripheral blood leukocytes[(10.19±3.67)×10 9/L,(8.53±2.83)×10 9/L vs.(16.11±7.81)×10 9/L, F=7.918,11.084, P=0.020,0.009],C-reactive protein[19.13(0.38,35.21)mg/L,8.05(0.10,18.00)mg/L vs. 59.34(24.20,131.90)mg/L, F=7.030,12.731, P=0.026,0.006],sJADAS scores[6.00(1.50,12.50)scores,3.00(0,12.50)scores vs. 20.00(11.50,28.00)scores, F=14.710,17.870, P=0.004,0.002]were decreased significantly. The doses of prednisone[0.13(0,0.45)mg/(kg·d),0.02(0,0.06)mg/(kg·d)vs. 0.42(0.16,1.47)mg/(kg·d), F=5.890,7.623, P=0.041,0.022]were significantly decreased.All the differences were statistically significant. Prednisone was successfully discontinued in 7 cases. Tocilizumab was gradually withdrawn in 3 cases,and tocilizumab administration interval was prolonged in 1 case. None of the 10 children had serious adverse reactions. Conclusion:Thalidomide is clinically effective in the treatment of sJIA,and can reduce the required dose of prednisone and prolong the tocilizumab free remission.

The Republic of China period (1912—1949) was an important stage of transition from traditional herbalism to clinical Chinese materia medica. The clinical application of Chinese materia medica became the focus of academic attention. During the Republic of China period, the research objectives, methods, and content of clinical Chinese materia medica were clarified, and the basic framework of Chinese materia medica was established through efficacy classification and item description. Based on the historical background at that time, striving for survival in adversity were the internal factors driving the construction of clinical Chinese materia medica, and the rise of academic education and the popularity of traditional Chinese medicine journals provided favorable conditions for the development of clinical Chinese materia medica. The clinical Chinese materia medica during the Republic of China period gradually formed a theoretical structure and core content that was distinctly different from that of traditional herbal medicine, which was integrated with the scientific research of Chinese materia medica and promoted the continuous development of Chinese materia medica together with other subdisciplines, presenting distinctive characteristics of the times and important academic significance.

Objective:To explore the efficacy and safety of endoscopic radial incision (ERI) for congenital membranous duodenal stenosis (MDS).Methods:The clinical data of 13 children with MDS receiving ERI in the Department of Gastroenterology of Xi'an Children's Hospital from May 2017 to December 2021 were reviewed and analyzed. The perioperative management, surgical procedures, postoperative complications and follow-up were summarized.Results:There were 5 boys and 8 girls with a median disease duration of 8 (2-20) months, and the median age of diagnosis was 13 months (5-30 months). The septum of 10 cases (10/13) was located in the descending part of the duodenum, and that of 3 cases (3/13) in the horizontal part. The papilla of 1 case (1/13) opened on the septum, that of 3 cases (3/13) within 5 cm of the mouth side of the septum, and that of 9 cases (9/13) within 5 cm of the anal side of the septum. The median diameter of the septal aperture was 3 mm (2-6 mm). All 13 children successfully underwent ERI with a median operation time of 20 min (15-32 min). The average surgical incision was 3 strokes (2-4 strokes), and the endoscope with outer diameter 9.9 mm could pass stenosis after ERI. The median incision diameter was 10 mm (10-12 mm). All patients achieved relief of clinical symptoms after ERI. One patient (1/13) suffered from the postoperative delayed bleeding, which was stopped by endoscopic titanium clamping. No intestinal perforation or duodenal papilla injury occurred, and median postoperative hospital stay was 6 days (5-10 days). The upper gastrointestinal angiogram and gastroscopy were repeated 3 months after ERI, and the median diameter of stenosis was 12 mm (10-15 mm), which was significantly dilated compared with before. The mean body weight increase at 1 month after ERI was 1.20 kg (0.50-1.80 kg), and the mean body weight increase at 3 months was 3.50 kg (2.50-4.00 kg), which reached the normal body weight of the same age.Conclusion:ERI is safe and effective for the treatment of MDS in children, and shows good clinical application and promotion value.
