This study aimed to explore the therapeutic mechanisms of Colquhounia Root Tablets(CRT) in treating diabetic kidney disease(DKD) by integrating biomolecular network mining with animal model verification. By analyzing clinical transcriptomics data, an interaction network was constructed between candidate targets of CRT and DKD-related genes. Based on the topological eigenvalues of network nodes, 101 core network targets of CRT against DKD were identified. These targets were found to be closely related to multiple pathways associated with type 2 diabetes, immune response, and metabolic reprogramming. Given that immune-inflammatory imbalance driven by metabolic reprogramming is one of the key pathogenic mechanisms of DKD, and that many core network targets of CRT are involved in this pathological process, receptor for advanced glycation end products(RAGE)-reactive oxygen species(ROS)-phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT)-nuclear factor-κB(NF-κB)-NOD-like receptor family pyrin domain containing 3(NLRP3) signaling axis was selected as a candidate target for in-depth research. Further, a rat model of DKD induced by a high-sugar, high-fat diet and streptozotocin was established to evaluate the pharmacological effects of CRT and verify the expression of related targets. The experimental results showed that CRT could effectively correct metabolic disturbances in DKD, restore immune-inflammatory balance, and improve renal function and its pathological changes by inhibiting the activation of the RAGE-ROS-PI3K-AKT-NF-κB-NLRP3 signaling axis. In conclusion, this study reveals that CRT alleviates the progression of DKD through dual regulation of metabolic reprogramming and immune-inflammatory responses, providing strong experimental evidence for its clinical application in DKD.

Ureaplasma urealyticum (UU) is a common pathogen colonizing or infecting the neonatal respiratory tract. It can be vertically transmitted from mother to infant, irrespective of the duration of premature rupture of membranes and the mode of delivery. UU infection is an important factor contributing to preterm birth and low birth weight and is closely associated with adverse outcomes such as bronchopulmonary dysplasia and neurodevelopmental impairment. Given the immaturity of neonatal immune and organ systems, pharmacologic treatment must balance efficacy and safety. Currently, no unified standard regimen has been established for the treatment of neonatal UU infection. This review summarizes pharmacotherapeutic options for neonatal UU infection to inform clinical practice.

Objective To investigate the anatomical and microscopic structures of interstitial fluid flow channels in the skin tissue of hand dorsum in human cadavers.Methods Totally 7 fresh cadavers within 12 hours post-mortem were included.MRI was used to observe the distribution of interstitial fluid flow from the first phalanx of the fingers to the wrist,precisely locating the flow channels.Based on imaging results,histological analyses were conducted to determine the histological characteristics of the flow channels.Furthermore,multi-immunofluorescence and microcomputed tomography(Micro-CT)techniques were employed to analyze the channels,and image post-processing was used to elucidate their anatomical structures at the microscopic level.Results After injecting a contrast agent into the first phalanx of ten finger specimens and applying repeated pressure,MRI image revealed centripetal long-range interstitial fluid flow along channels distinct from blood vessels and lymphatic vessels.Histological analysis and Micro-CT further confirmed that the flow primarily occurred within the fibrous connective tissue and adventitia of the skin.Conclusion The orderly fibrous connective tissue and adventitia in the skin form the interstitial fluid flow channels in the human hand dorsum skin,named as"stromal membrane channels"in the skin.

Objective: To investigate the current status and influencing factors of sleep disorders among pregnant women, so as to provide insights into health management during pregnancy. Methods: Pregnant women who underwent prenatal checkups at Hangzhou Obstetrics and Gynecology Hospital from January to October 2023 were selected as subjects, and general data including age, pregnancy period and exercise were collected through questionnaire surveys. Sleep quality, pregnancy stress, anxiety and depression were evaluated using Pittsburgh Sleep Quality Index, Pregnancy Stress Rating Scale, Pregnancy-related Anxiety Scale and Edinburgh Postnatal Depression Scale, respectively. Factors affecting sleep disorders among pregnant women were analyzed using a multivariable logistic regression model. Results: A total of 386 pregnant women was surveyed, with a mean age of (30.28±4.65) years, including 20.47% in the first trimester, 47.93% in the second trimester and 31.61% in the third trimester. Women with anxiety and depression accounted for 14.51% and 21.76%, respectively. Pregnancy stress was mainly moderate, accounting for 51.04%. There were 106 pregnant women with sleep disorders, accounting for 27.46%. Mutivariable logistic regression analysis showed that age (≥35 years, OR=1.656, 95%CI: 1.094-2.503), pregnancy period (third pregnancy, OR=2.097, 95%CI: 1.213-3.621), regular exercise in the past 6 months (OR=0.376, 95%CI: 0.210-0.670), anxiety (OR=2.794, 95%CI: 1.545-5.048), depression (OR=3.501, 95%CI: 1.877-6.529) and pregnancy stress (moderate, OR=1.355, 95%CI: 1.018-1.801; severe, OR=2.538, 95%CI: 1.417-4.540) were the factors affecting sleep disorders among pregnant women. Conclusions Sleep disorders of pregnant women is influenced by age, pregnancy period, pregnancy stress, anxiety, depression and exercise. It is necessary to identify high-risk individuals with sleep disorders early, and to provide psychological intervention and prenatal health guidance.

This study aimed to investigate the influence of anti-cross-reactive carbohydrate determinant IgE antibodies (anti-CCD IgE) on the detection of allergen-specific IgE (sIgE) antibodies, as well as the application value of anti-CCD IgE adsorbents in detecting allergen sIgE. In this cross-sectional study, a total of 2 636 test samples from patients who received treatment in West China Hospital of Sichuan University and tested allergen sIgE using the western blot method from October 2020 to May 2021 were analyzed. In these samples, 709 samples tested postive of allergen sIgE. 46 stochastic venous serum samples that tested positive in both sIgE and anti-CCD IgE and 1 serum sample that tested positive in sIgE but negative in anti-CCD IgE were collected. These samples were processed by anti-CCD IgE adsorbents, followed by allergen sIgE detection. The difference between the two detection results before and after adsorption was analyzed. The allergen test results showed that the positive rate of anti-CCD IgE in samples was 2.6% (69/2 636) during the period of sample collection. After treatment with anti-CCD IgE adsorbents, the top three allergen-sIgE of the positive rate changed from tree combination 2 (willow/poplar/elm), common ragweed and peanut to dust mite combination, cockroach and crab. The positive anti-CCD IgE results of 46 samples all turned negative and the total positive sIgE antibody dropped by 62.8%; the positive rate of sIgE antibodies with the class result ≥2 significantly decreased after treatment with anti-CCD IgE adsorbents, especially the positive rate of common ragweed dropped by 96.2%. The results of positive samples showed that multiple sIgE antibodies declined by different ranges, involving up to 11 antibodies with a maximum decline of 4 classes. Strongly positive sIgE antibodies (the class result ≥4) also had a high conversion rate of negative (25.0%-100%). The positive sIgE antibodies in about 60% of the samples decreased by more than 2, and the sIgE antibodies in 17.4% of the samples turned completely negative. There was no change in the allergen sIgE detection results of the sample with negative anti-CCD IgE after treatment. In conclusion, sIgE antibodies including targeting common ragweed, humulus, tree combination 2 (willow/poplar/elm), etc. are susceptible to false positives caused by anti-CCD IgE. Treatment of samples with anti-CCD IgE adsorbents can significantly reduce the risk of false positives caused by anti-CCD IgE. It is necessary to pretreat samples that were anti-CCD IgE positive with anti-CCD IgE adsorbents, which can make laboratory results more accurate and provide a reference for diagnosis and prevention of allergic diseases.

Objective:To study the expressions of bronchoalveolar lavage fluid(BALF), C-reactive protein (C reactive protein, CRP), procalcitonin (PCT) and Interleukin 6 (IL-6) in mechanically ventilated patients with chronic obstructive pulmonary diseases (COPD) and their clinical significance.Methods:A total of 128 COPD patients with mechanical ventilation admitted to the Third People's Hospital of Chengdu from September 2022 to September 2023 were selected as the study subjects. They were divided into VAP group and non-VAP group according to the occurrence of ventilator associated pneumonia (VAP). Comparison of general data between the two groups, measurement data in line with normal distribution were expressed xˉ± s, and independent sample t test was used to compare the mean between groups. Enumeration data were expressed as constituent ratio, and χ2 test was used to compare between groups. Multivariate Cox regression was used to analyze the influencing factors of VAP in COPD patients. The diagnostic value of CRP, procalcitonin and IL-6 in BALF and serum for VAP was evaluated by receiver operating characteristic (ROC) curve. Results:There were 32 cases of VAP and 96 cases of non-VAP in 128 COPD patients with mechanical ventilation. In the VAP group, the duration of mechanical ventilation was (5.12±0.48) days, and 13 patients (40.63%) had used antibiotics within 3 months, while in the non-VAP group, the duration of mechanical ventilation was (4.79±0.69) days, and 56 patients (61.46%) had used antibiotics within 3 months, respectively. There were significant differences between the two groups ( t=2.51, χ2=4.23, all P<0.05). The levels of CRP, procalcitonin and IL-6 in BALF of VAP group were (26.46±6.78) mg/L, (2.47±0.69) ng/L and (751.46±126.44), and in the non-VAP group, they were (20.47±6.26) mg/L, (1.12±0.32) ng/L and (447.89±68.69) μg/L, respectively. There were significant differences between the two groups ( t=4.59, 15.00, 17.18, all P<0.001). The serum levels of CRP, procalcitonin and IL-6 in VAP group were (124.78±26.32) mg/L, (10.53±2.20) ng/L and (221.69±45.46). The non-VAP group was (96.78±24.96) mg/L, (6.46±1.89) ng/L and (146.36±42.34) μg/L, respectively ( t=5.42, 10.12, 8.56; all P<0.001). Multivariate Cox regression analysis showed that mechanical ventilation time, BALF and serum CRP, procalcitonin and IL-6 were independent factors affecting the occurrence of VAP in COPD patients ( OR values were 1.578, 1.687, 1.669, 1.844,1.645, 1.775 and 1.659, respectively). 95% CI were 1.017-2.447, 1.066-2.669, 1.076-2.588, 1.148-2.963, 1.086-2.493, 1.172-2.690 and 1.084-2.538, all P<0.05). ROC curve showed that the AUC of CRP, procalcitonin and IL-6 in BALF and serum were 0.758/0.792, 0.965/0.930 and 0.977/0.900 respectively ( P values were 0.049/0.046, 0.030/0.030 and 0.021/0.033, respectively). Conclusion:The expressions of CRP, procalcitonin and IL-6 in BALF and serum of COPD patients with mechanical ventilation have high clinical diagnostic value, which can assist the diagnosis of early VAP.

Objective To investigate the medication rules of tradition Chinese medicine for the treatment of ulcerative colitis(UC)at remission stage by data mining method,thus to provide reference for clinical prescription and medication.Methods The clinical research or medical case report of UC remission treated by Chinese medicine issued in CNKI,Wanfang Data and VIP from July 2000 to December 2022 were retrieved.Excel 2019 was used to analyze the frequency statistics,and the distribution of the nature,flavor and meridian tropism of the prescribed drugs in the included literature.Modeler 18.0 and SPSS Statistics 26.0 were used for association rules and cluster analysis,and Cytoscape 3.9.1 was used to construct the network diagram of the associated drugs.Results A total of 121 articles were included in the analysis,involving 167 drugs,of which 24 drugs were frequently used,mainly including Atractylodis Macrocephalae Rhizoma,Poria,Aucklandiae Radix,Coptidis Rhizoma,Codonopsis Radix,Paeoniae Radix Alba,Coicis Semen,Astragali Radix,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Angelicae Sinensis Radix,Citri Reticulatae Pericarpium,and Dioscoreae Rhizoma.According to the therapeutic actions,the drugs were mainly classified into deficiency-supplementing drugs,heat-clearing drugs,qi-regulating drugs,urination-promoting and dampness-percolating drugs,blood-stanching drugs,exterior-relieving drugs,interior-warming drugs,astringent drugs,dampness-resolving drugs,and blood-activating and stasis-resolving drugs.The medicinals were mainly warm,mild and cold in nature,and were sweet,bitter and pungent in flavor.Most of the drugs had the meridian tropism of the spleen,stomach,lung and liver.A total of 25 drug association rules were mined out,and five prescriptions were obtained after cluster analysis.Conclusion The Chinese medicine prescriptions for the treatment of UC remission usually deprive from the classical formulas such as Shenling Baizhu San,Sishen Pills,and Tongxie Yaofang.The compatibility of drugs reflects the thoughts of treating UC remission from the perspective of spleen,and embodies the therapies of strengthening the spleen and removing dampness,promoting qi and regulating blood,and focusing on tonifying ministerial fire and supporting yang in the later stage,which has the characteristics of treating both symptoms and root causes simultaneously by using multiple drugs through multiple methods.
