ObjectiveTo explore the pharmacological mechanism involved in the treatment of allergic cough （AC） by Xiaoer Huatan Zhike granules （XEHT） based on proteomics and network pharmacology. MethodsAfter sensitization by intraperitoneal injection of 1 mL suspension containing 2 mg ovalbumin （OVA） and 100 mg aluminum hydroxide， a guinea pig model of allergic cough was constructed by nebulization with 1% OVA. The modeled guinea pigs were randomized into the model， low-， medium- and high-dose （1， 5， 20 g·kg^-1， respectively） XEHT， and sodium montelukast （1 mg·kg^-1） groups （n=6）， and another 6 guinea pigs were selected as the blank group. The guinea pigs in drug administration groups were administrated with the corresponding drugs by gavage， and those in the blank and model groups received the same volume of normal saline by gavage， 1 time·d^-1. After 10 consecutive days of drug administration， the guinea pigs were stimulated by 1% OVA nebulization， and the coughs were observed. The pathological changes in the lung tissue were observed by hematoxylin-eosin staining. The enzyme-linked immunosorbent assay was performed to measure the levels of C-reactive protein （CRP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， superoxide dismutase （SOD）， and malondialdehyde （MDA） in the bronchoalveolar lavage fluid （BALF） and immunoglobulin G （IgG） and immunoglobulin A （IgA） in the serum. Immunohistochemistry （IHC） was employed to observe the expression of IL-6 and TNF-α in the lung tissue. Transmission electron microscopy was employed observe the alveolar type Ⅱ epithelial cell ultrastructure. Real-time PCR was employed to determine the mRNA levels of IL-6， interleukin-1β （IL-1β）， and TNF-α in the lung tissue. Label-free proteomics was used to detect the differential proteins among groups. Network pharmacology was used to predict the targets of XEHT in treating AC. The Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis was performed to search for the same pathways from the results of proteomics and network pharmacology. ResultsCompared with the blank group， the model group showed increased coughs （P<0.01）， elevated levels of CRP， TNF-α， IL-6， and MDA and lowered level of SOD in the BALF （P<0.05， P<0.01）， elevated levels of IgA and IgG in the serum （P<0.05， P<0.01）， congestion of the lung tissue and infiltration of inflammatory cells， increased expression of IL-6 and TNF-α （P<0.01）， large areas of low electron density edema in type Ⅱ epithelial cells， obvious swelling and vacuolization of the organelles， karyopyknosis or sparse and dissolved chromatin， and up-regulated mRNA levels of IL-6， IL-1β， and TNF-α （P<0.01）. Compared with the model group， the drug administration groups showed reduced coughs （P<0.01）， lowered levels of CRP， TNF-α， IL-6， and MDA and elevated level of SOD in the BALF （P<0.05， P<0.01）， alleviated lung tissue congestion， inflammatory cell infiltration， and type Ⅱ epithelial cell injury， and decreased expression of IL-6 and TNF-α （P<0.01）. In addition， the medium-dose XEHT group and the montelukast sodium group showcased lowered serum levels of IgA and IgG （P<0.05， P<0.01）. The medium- and high-dose XEHT groups and the montelukast sodium showed down-regulated mRNA levels of IL-6， IL-1β， and TNF-α and the low-dose XEHT group showed down-regulated mRNA levels of IL-6 and TNF-α （P<0.05， P<0.01）. Phospholipase D， mammalian target of rapamycin （mTOR）， and epidermal growth factor receptor family of receptor tyrosine kinase （ErbB） signaling pathways were the common pathways predicted by both proteomics and network pharmacology. ConclusionProteomics combined with network pharmacology reveal that XEHT can ameliorate AC by regulating the phospholipase D， mTOR， and ErbB signaling pathways.

OBJECTIVE To study the interventional effect and mechanism of 1，8-cineole on pancreatic β cell ferroptosis induced by type 2 diabetes. METHODS In vitro ferroptosis model was established in pancreatic β cells of mice by using high glucose. The effects of low-dose and high-dose 1，8-cineole （0.25， 0.5 μmol/L） on the level of Fe2+ in pancreatic β cells were investigated. The effects of 1，8-cineole （0.5 μmol/L） combined with ferroptosis inducer Erastin （20 μmol/L） and ferroptosis inhibitor Ferrostatin-1 （20 μmol/L） on the protein expressions of glutathione peroxidase-4 （GPX4） and cyclooxygenase-2 （COX2） were also detected. The type 2 diabetes model mice were established by feeding high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin. The effects of low-dose and high-dose 1，8-cineole （50， 200 mg/kg） on the pathological morphology of pancreatic tissue， the content of iron as well as the protein expressions of GPX4 and COX2 were investigated. RESULTS The results of the cell experiment showed that compared with the model group， pretreatment with 1，8-cineole significantly reduced intracellular Fe2+ levels and upregulated GPX4 protein expression， while downregulated COX2 protein expression in pancreatic β cells （P＜0.05）. After combining with Ferrostatin-1， the expression trends of the above two proteins were the same， while there was no statistically significant difference after combining with Erastin. The results of animal experiments showed that compared with the model group， after intervention with 1，8-cineole， the structure of the pancreatic islets in mice recovered intact and their morphology improved； the iron content of pancreatic tissue and protein expression of COX2 were decreased significantly （P＜0.05）， while protein expression of GPX4 was increased significantly （P＜0.05）. CONCLUSIONS 1，8-cineole could ameliorate pancreatic β cell injury induced by diabetes， the mechanism of which may be related to reducing intracellular iron deposition and regulating ferroptosis-related proteins.

Objective:Clinical characteristics and diagnosis and treatment process was reported and analyzed of a patient with brucellosis complicated with thyroid abscess, providing reference for the clinical diagnosis of brucellosis complicated with thyroid abscess.Methods:Clinical medical records of a patient with brucellosis complicated with thyroid abscess who was treated at the General Surgery Department of Yanchi County People's Hospital in Wuzhong City, Ningxia Hui Autonomous Region in November 2021 were collected. The clinical manifestations, blood routine, brucella antibodies, thyroid function, bacterial culture, thyroid ultrasound and other examination results, as well as the diagnosis and treatment process, were comprehensively analyzed. Results:The patient was a male, 61 years old, who presented with a neck mass without typical clinical manifestations of brucellosis. Thyroid ultrasound revealed a space occupying lesion, and the preliminary diagnosis was thyroid cystadenoma. Thyroid right lobe and isthmus resection surgery was performed. During the operation, it was found that some of the thyroid glands were tightly adhered to the cervical blood vessels, so the resection surgery was changed to abscess drainage, and the drainage fluid was purulent and bloody. The bacterial culture result of thyroid purulent fluid (intraoperative puncture fluid and postoperative drainage fluid) was brucella lamblia, and the serum brucella test tube agglutination test titer was 1 ∶ 400 (+++). The patient improved and was discharged after local drainage and anti brucella treatment. Follow up for 4 months showed no abnormalities. Conclusions:Brucellosis which begins with a local infection of the thyroid gland is extremely rare, with no characteristic clinical manifestations, and is prone to misdiagnosis. Timely correction of the surgical plan during the treatment process avoids the removal of the patient's thyroid, which has a certain clinical reference value.

Objective To investigate the impact of healthy eating patterns on the mortality rate and in-cidence rates of end-stage kidney disease(ESKD)and cardiovascular disease(CVD)in the patients with chronic kidney disease(CKD)by meta analysis.Methods The studies on the relationship between the dietary patterns on the mortality,and the incidence rates of ESKD and CVD in the patients with CKD were retrieved from PubMed,Embase,Cochrane Library,CNKI,Wanfang Database and VIP Database.The retrieval time was from the database establishment to January 2023.The two researchers independently screened the literatures,ex-tracted the data and conducted the literature quality evaluation.The RevMan5.3 software was used for the meta-analysis of the included literatures.Results A total of 10 studies were included in this study,involving 27 291 patients.The results showed that the mortality(HR=0.70,95％CI:0.57-0.87,Z=3.18,P=0.001)and the ESKD incidence rate(HR=0.80,95％CI:0.71-0.91,Z=3.44,P＜0.001)and CVD inci-dence rate(HR=0.77;95％CI:0.61-0.97,Z=2.21,P=0.003)had statistical differences between the pa-tients with high dietary score and the patients with low dietary score.Conclusion Persisting in the healthy dieta-ry patterns could decrease the mortality rate,and incidence rates of ESKD and CVD in the patients with CKD.

Objective:To explore the genetic basis for a fetus with Cardiac valvular dysplasia type 1 (CVDP1).Methods:A CVDP1 fetus identified at the Ningbo Women and Children′s Hospital on July 7, 2022 was selected as the study subject. Clinical data of the fetus was collected. The fetus and its parents were subjected to trio-whole exome sequencing (trio-WES), and candidate variants were verified by Sanger sequencing.Results:The fetus had exhibited generalized edema, complex cardiac malformation, abdominal effusion, and enhanced intestinal and renal parenchymal echoes. Trio-WES revealed that it has harbored compound heterozygous variants of the PLD1 gene, namely c. 2977C>T (p.R993*) and c. 1460G>A (p.W487*), which were respectively inherited from its father and mother. Neither variant was reported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 2977C>T (p.R993*) variant was evaluated to be likely pathogenic (PVS1_Moderate+ PM2_Supporting+ PM3+ PP4), whilst the c. 1460G>A (p.W487*) variant was evaluated to be pathogenic (PVS1+ PM2_Supporting+ PP4). Conclusion:The c. 2977C>T (p.R993*) and c. 1460G>A (p.W487*) compound heterozygous variants of the PLD1 gene probably underlay the CVDP1 in the fetus. Above discovery has enriched the mutational spectrum of the PLD1 gene and provided a guidance for genetic counseling and prenatal diagnosis in this family.

Objective:To analyze the blood differential metabolites of patients with intrahepatic cholestasis (IHC) by liquid chromatography-mass spectrometry metabolomics technology so as to find potential metabolic target.Method:Serum samples were collected from thirty patients with intrahepatic cholestasis and thirty healthy individuals after metabolomics analysis. The differential metabolites were initially screened based on the multiple differences and significance. KEGG enrichment analysis was performed on the differential metabolites to determine the candidate targets. The potential clinical application value of these characteristic metabolites was analyzed using the receiver operating characteristic curve.Result:A total of thirty patients with intrahepatic cholestasis and thirty healthy adults were included. The age difference between the two groups was not statistically significant ( P>0.05). The clinical condition was consistent with the statistically significant differences in liver biochemical indicators, blood routine, coagulation, and inflammatory indicators between the two groups ( P<0.05). Furthermore, a blood metabolomics screening analysis revealed 99 differentially expressed metabolites associated with intrahepatic cholestasis. Of these, 15 showed statistically significant differences. Glucose, lipid, and energy metabolisms were the various primary types of differential metabolites involved. The receiver operating characteristic curve>0.9 included the following twelve kinds of metabolites: 1H-indole-3-carboxaldehyde, 6-hydroxy-1H-indole-3-acetamide, phenylalanyl tryptophan, 1-methylguanosine, 2-ethoxy-5-methylpyrazine, p-hydroxybenzaldehyde, 5-(2-chlorophenyl)-3,4-dihydro-2H-pyrrole, methylthioadenosine, alanylisoleucine, anabsinthin, N-acetyl-DL-histidine monohydrate, N-methylnicotinamide, and others. The fifteen metabolites that were previously identified and calculated according to the differential quantitative value of the metabolite corresponding ratio exhibited fold-changes in the upregulated and downregulated potential biomarkers (phenylalanine tryptophan, phenylalanine, 5'-methylthioadenosine, anabsinthin, and N-methylnicotinamide) in combination with the area under the receiver operating characteristic curve>0.9. Conclusion:Phenylalanyl tryptophan, phenylalanylalanine, 5'-methylthioadenosine, anabsinthin, and N-methylnicotinamide may serve as potential metabolic markers to distinguish patients with cholestasis from healthy controls. N-methylnicotinamide, among them, is of great importance as a potential marker.
