ObjectiveTo investigate differential metabolites associated with browning in the post-harvest processing of Pinelliae Rhizoma， providing data support for elucidating the key metabolites and metabolic pathways involved in browning， and developing safe and efficient sulfur-free processing techniques. MethodsUltra-performance liquid chromatography-triple quadrupole/linear ion trap mass spectrometry（UPLC-QTRAP-MS/MS） was used to detect the metabolites of Pinelliae Rhizoma at different browning stages（0， 8， 16 h） for widely targeted metabolomics. Subsequently， Multivariate statistical analysis of metabolites was conducted using principal component analysis（PCA）， hierarchical cluster analysis（HCA）， orthogonal partial least squares-discriminant analysis（OPLS-DA）， and K-means cluster analysis. Differential metabolites at different browning stages were screened based on variable importance in the projection（VIP） value>1 and |log₂fold change（FC）|≥1， and metabolic pathway enrichment analysis was performed using Kyoto Encyclopedia of Genes and Genomes（KEGG）. ResultsA total of 1 416 metabolites were identified across the three browning stages of Pinelliae Rhizoma， predominantly comprising amino acids and their derivatives（239）， lipids（219）， alkaloids（156）， phenolic acids（121）， terpenoids（113）， and flavonoids（111）. A two-by-two comparison of the three browning phases， yielded 622 differential metabolites that were significantly enriched in the phenylpropanoid biosynthesis， flavone and flavonol biosynthesis， and purine metabolic pathway. Further analysis revealed that carbohydrates such as D-mannose and turanose， phenolic acids such as 1-O-caffeoyl-6-O-glucosyl-β-D-glucose， dicaffeoylshikimic acid， and flavonoids such as epigallocatechin gallate， vitexin-7-O-rutinoside， luteolin-7-O-（6″-malonyl）glucoside-5-O-arabinoside， catechin gallate， epicatechin gallate， isovitexin-7-O-glucoside-2″-O-rhamnoside， apigenin-7-O-rutinoside-4ʹ-O-sophoroside， 3，5，3ʹ，4ʹ，5ʹ-penta-hydroxyflavan-7-gallate may act as browning substrates and play important roles in the browning process. ConclusionCarbohydrates， phenolic acids， and flavonoids may serve as key substrates in the browning process of Pinelliae Rhizoma， involving pathways such as phenylpropanoid biosynthesis， flavone and flavonol biosynthesis， and purine metabolism， which can provide a theoretical basis for further exploration of the browning mechanism.

Bone morphogenetic proteins (BMPs) are multifunctional growth factors of the transforming growth factor β (TGF-β) superfamily. They regulate steroid secretion from mammalian granulosa cells, promote granulosa cell survival and proliferation, and inhibit follicular atresia, luteinization, and granulosa cell apoptosis, thereby promoting the development and maturation of mammalian follicles. At the same time, BMPs play an important role in embryonic morphogenesis, induction of uterine receptivity, and blastocyst attachment. This paper describes the effects of BMPs on mammalian follicular and embryonic development and the roles of BMPs in female reproduction, focusing on the process in which BMPs promote follicular maturation by regulating steroid secretion from granulosa cells during mammalian oocyte maturation. This review aims to provide a reference for further research on mammalian oocyte culture and improvement of reproductive efficiency in female animals.

ObjectiveTo investigate the current status and related factors of maternal influenza vaccination willingness among pregnant and postpartum women in Shanghai and Liaoning Province, China, and to explore the facilitators and barriers affecting vaccination uptake, so as to provide references for future practices in promoting maternal influenza immunization in China. MethodsA convergent mixed-methods research was conducted. From January to March 2024, a questionnaire survey was conducted among women attending prenatal and postnatal care at 7 medical institutions in Shanghai and Dalian, Liaoning Province, which aimed to assess pregnant women’s knowledge about influenza vaccine and their willingness to vaccination during pregnancy, as well as to identify the related factors. In addition, purposive sampling method was used to conduct in-depth interviews with pregnant women and perinatal healthcare service providers to explore their perspectives on influenza vaccination during pregnancy, including the reasons for their willingness or unwillingness to receive ( or recommend) the vaccine, and the relevant facilitators and barriers to vaccination. ResultsA total of 366 pregnant and postpartum women participated in the questionnaire survey, and 9.56% (35/366) of them were willing to receive the influenza vaccine during pregnancy. The results of multivariate logistic stepwise regression analyses showed that primipara (aOR=0.158, 95%CI: 0.037‒0.671, P=0.012), family members’ support for influenza vaccination during pregnancy (aOR=0.015, 95%CI: 0.003‒0.082, P<0.001) were associated with higher willingness to receive influenza vaccine during pregnancy. Absence of influenza infection during pregnancy (aOR=5.383, 95%CI: 1.801‒16.092, P<0.001), and lack of knowledge regarding influenza vaccination during pregnancy (aOR=11.294, 95%CI: 3.593‒35.496, P<0.01) were associated with lower willingness to receive influenza vaccine during pregnancy. Qualitative findings indicated that the facilitators to vaccination willingness among pregnant and postpartum women included the recommendation of healthcare service providers, adequate knowledge of influenza vaccine information and family members’ support for vaccination. Conversely, the barriers to vaccination willingness included low recommendation from the healthcare service providers, lack of knowledge about the safety of influenza vaccine during pregnancy and inadequate attention to influenza and influenza vaccine. ConclusionThe willingness to receive influenza vaccination among pregnant and postpartum women in Shanghai and Liaoning Province is relatively low. It is recommended that China should promptly improve the evidence-based system for the safety and efficacy of influenza vaccines for pregnant and postpartum women, along with an establishment of the mechanism for addressing adverse reactions. Furthermore, it is essential to enhance educational outreach to pregnant and postpartum women, their families, and healthcare service providers, thereby increasing the accessibility of information regarding influenza vaccination, which are expected to enhance the willingness of pregnant and postpartum women to receive the vaccine.

Objective:To explore the clinical effect of vitamin A in the adjuvant treatment of bronchial asthma in children and its influence on serum transforming growth factor-β1 (TGF-β1), eosinophils (EOS) and interleukin-17 (IL-17) levels.Methods:A prospective study was conducted on 110 children with bronchial asthma who received treatment in Department of Pediatrics, Xi'an Central Hospital from January 2022 to December 2023. Based on the principle of balanced and comparable baseline characteristics between groups, they were randomly divided into a control group and an observation group, with 55 cases in each group, using a random number table method. The control group was treated with routine pediatric bronchial asthma therapy, while the observation group was added with vitamin A adjuvant therapy on the basis of the control group. After 15 days of continuous treatment, the scores of asthma control condition (Childhood-Asthma Control Test (C-ACT), Asthma Control Questionnaire (ACQ)) in the two groups were evaluated. The pulmonary ventilation function (forced expiratory volume in one second (FEV 1), forced expiratory volume in one second/forced vital capacity (FEV 1/FVC), peak expiratory flow (PEF)), serum inflammatory factors (TGF-β1, EOS, IL-17) and immune function indicators (T helper 17 cell (Th17), T helper 2 cell (Th2), regulatory T cell (Treg) ) were compared between groups of children before treatment and after 15 days of treatment. Measurement data with normal or approximate distribution were expressed as xˉ± s, and independent sample t test was used for comparison between groups. Enumeration data were expressed as percentage, and chi-square test was adopted for between-group comparison. Results:After 15 days of treatment, the C-ACT score with (16.20±3.14) points in observation group was higher than (14.80±2.62) points in control group while the ACQ score with (30.30±4.14) points was lower than (34.60±6.23) points in control group, with statistical differences between groups (t values were 2.54 and 4.26; P values were 0.012 and <0.001).

Conclusion:Vitamin A adjuvant therapy is helpful to the control of bronchial asthma, and it can effectively improve the pulmonary function, reduce the inflammatory reaction and enhance the body's immunity.

Objective To explore the predictive value of combined serum soluble hemoglobin scavenger receptor 163(sCD163),hypersensitive C-reactive protein(hs-CRP),and procalcitonin(PCT)for stroke-associated pneumonia(SAP).Methods A total of 100 patients with acute ische-mic stroke admitted to the First Hospital of Zhangjiakou from October 2021 to January 2023 were se-lected as the study subjects.According to whether they developed SPA within 7 days of admission,they were divided into SAP group(n=64)and non-SAP group(n=36).Based on pneumonia se-verity index(PSI),patients in the SAP group were further divided into mild SAP group and severe SAP group.Enzyme-linked immunosorbent assay(ELISA)was used to detect the serum levels of sCD163,hs-CRP,and PCT.The clinical data of the patients were collected and compared.Pearson's method was used to analyze the correlation between the PSI score and the serum levels of sCD163,hs-CRP,and PCT in SAP patients.Multivariate Logistic regression analysis was employed to screen for factors influencing the occurrence of SAP.Receiver operating characteristic(ROC)curve analy-sis was used to evaluate the predictive efficacy of serum sCD163,hs-CRP,and PCT for the occur-rence of SAP.Results The proportion of patients with dysphagia and the National Institutes of Health Stroke Scale(NIHSS)score in the SAP group were significantly higher than those in the non-SAP group(P＜0.05).The serum levels of sCD163,hs-CRP,and PCT in the SAP group were significantly higher than those in the non-SAP group(P＜0.05).The serum levels of sCD163,hs-CRP,and PCT in the severe SAP group were significantly higher than those in the mild SAP group(P＜0.05).Pearson's correlation analysis showed that the PSI score was positively correlated with the serum levels of sCD163,hs-CRP and PCT in SAP patients(r=0.356,0.413,0.391,P＜0.001).Logistic regression analysis revealed that serum sCD163,hs-CRP,PCT,NIHSS score,and dysphagia were all influencing factors for the occurrence of SAP(P＜0.05).The areas under the curve(AUC)for predicting SAP using serum sCD163,hs-CRP,PCT and their combina-tion were 0.842,0.924,0.866 and 0.973,respectively,with sensitivities of 73.44％,84.37％,67.19％and 90.62％,and specificities of 88.89％,83.33％,97.22％and 94.44％,respectively.The predictive value of the combined detection was superior to that of the individual detection of ser-um sCD163,hs-CRP and PCT(P＜0.05).Conclusion The serum levels of sCD163,hs-CRP,and PCT are elevated in SAP patients,and their changes are closely related to the severity of the disease.The combined detection of these three indicators has a high value in predicting the occur-rence of SAP and may serve as auxiliary markers for predicting early SAP.

Objective To investigate the value of serum thymidine kinase 1(TK1),hypoxia-inducible fac-tor-1α(HIF-1α)and squamous cell carcinoma antigen(SCC)in the diagnosis and prognosis of esophageal cancer.Methods A total of 105 patients with esophageal cancer treated in the Qinhuai Medical Zone of East-ern Theater General Hospital from February 2019 to October 2021 were selected as the study group,and 80 healthy subjects were selected as the control group during the same period.The serum levels of TK1,HIF-1αand SCC were compared between study group,control group and patients with different pathological charac-teristics.Patients with esophageal cancer were followed up for 3 years,and the overall survival(OS)and pro-gression-free survival(PFS)were recorded.Receiver operating characteristic curve was used to analyze the di-agnostic efficiency of serum TK1,HIF-1α and SCC combined detection for esophageal cancer,Pearson correla-tion analysis was used to analyze the correlation between the serum indicators,and Kaplan-Meier survival a-nalysis was used to analyze the OS and PFS of patients with different serum levels of TK1,HIF-1α and SCC.Multivariate COX regression was performed to analyze prognostic factors.Results Compared with the control group,the serum TK1,HIF-1α and SCC levels in the study group increased(P＜0.05).The area under the curve(AUC)of serum TK1,HIF-1α,SCC alone and combined for diagnosis of esophageal cancer were 0.893,0.744,0.841,0.922,respectively,and their combined diagnoses of esophageal cancer had the largest AUC.Se-rum TK1,HIF-1α and SCC in patients with different TNM stages and differentiation stages were significantly different(P＜0.05).Serum TK1,HIF-1α and SCC in patients with lymph node metastasis were higher than those without lymph node metastasis(P＜0.05).Serum TK1 was positively correlated with HIF-1α and SCC levels in patients with esophageal cancer(P＜0.05).The survival functions of OS and PFS in TK1,HIF-1αand SCC low expression group were better than those in high expression group(P＜0.05).Multivariate COX regression analysis showed that low differentiation and lymph node metastasis were independent risk factors for poor prognosis in esophageal cancer patients(P＜0.05).Conclusion Serum levels of TK1,HIF-1α and SCC are increased in patients with esophageal cancer,the combined diagnosis of the three is effective.The high expression of TK1 and HIF-1αand SCC will shorten OS and PFS.

OBJECTIVE: To observe the clinical effect of needle cauterization on vitiligo with deficiency cold and blood stasis. METHODS: A total of 62 patients of vitiligo with deficiency cold and blood stasis were randomly divided into an observation group and a control group, 31 cases each group.On the basis of 308 nm excimer light irradiation combined with ironing with Chinese medicine, the control group was treated with tacrolimus ointment for external use, twice a day; the observation group was treated with needle cauterization at vitiligo spots, once a week.Both groups were treated for 10 weeks. Before and after treatment, the area of vitiligo spot, TCM syndrome score, serum levels of inflammatory indexes (interleukin[IL]-6 and IL-17) were observed in the two groups, and the clinical effect was evaluated. RESULTS: After treatment, the areas of vitiligo spot, TCM syndrome scores and serum levels of IL-6, IL-17 were decreased compared with those before treatment in both groups (P<0.05), and the above indexes in the observation group were lower than those in the control group (P<0.05). The total effective rate in the observation group was 93.5% (29/31), which was higher than 77.4% (24/31) in the control group (P<0.05). CONCLUSION Needle cauterization could reduce the areas of vitiligo spot in patients of vitiligo with deficiency cold and blood stasis, improve the clinical symptoms, its mechanism may be related to the reduction of serum levels of inflammatory indexes.

Viral hepatitis and related liver diseases are among the most significant global healthcare issues. Viral hepatitis not only directly affects liver function but also interacts with the gut microbiota through the gut-liver axis. Imbalance in the gut microbiota may be associated with the occurrence, development and prognosis of viral hepatitis and related liver diseases. Detection and analysis of the gut microbiota can help to comprehensively understand the health status of patients with viral hepatitis and related liver diseases, providing a basis for early diagnosis. Recovery of gut microbiota dysbiosis may help to alleviate liver inflammation and to improve liver function. Regulating the gut microbiota through gut microbiota transplantation, probiotics and prebiotics may be new strategies for treating viral hepatitis and related liver diseases. By analyzing the latest research progress of gut microbiota in viral hepatitis and related liver diseases, this article provides new methods for the diagnosis and treatment of viral hepatitis and related liver diseases.
