ObjectiveTo explore the possible mechanism of Bimin Formula （鼻敏方） in treating lung-spleen qi deficiency syndrome of allergic rhinitis （AR） with high mucin secretion. MethodsThirty-four SD rats were randomly divided into a blank group （8 rats）， a model group （8 rats）， a low-dose Bimin Formula group （8 rats）， and a high-dose Bimin Formula group （10 rats）. Except for the blank group， the other groups were subjected to AR lung-spleen qi deficiency rat models induced by smoking， gavage of Ginkgo biloba leaf extract， and ovalbumin. After modeling， rats in the low- and high-dose Bimin Formula groups were given Bimin Formula concentrate （concentration of 2.16 g/ml） by gavage at doses of 1.08 g/100 g and 2.16 g/100 g， respectively， while rats in the model group were given 0.5 ml/100 g of normal saline by gavage， once daily for 28 days； the blank group was not intervened. Behavioral assessments were performed after intervention. ELISA was used to detect the levels of peripheral blood total immunoglobulin E （IgE）. HE staining was used to observe the pathological changes of nasal mucosa epithelium in rats， while immunohistochemistry was used to detect the expression of transmembrane protein 16A （TMEM16A） and mucin 5AC （MUC5AC） protein in nasal mucosa. Western Blot was used to detect the expression of nuclear factor kappa B （NF-κB） protein， and RT-PCR was used to detect the expression of TMEM16A， MUC5AC， and NF-κB mRNA in nasal mucosa. ResultsHE staining showed that the nasal mucosa epithelial cell structure in the blank group was intact without shedding， swelling， or necrosis； the nasal mucosa epithelial tissue of rats in the model group was thickened and partially shed， with infiltration of eosinophils and lymphocytes visible； the pathological changes in nasal mucosa tissue of rats in the high- and low-dose Bimin Formulagroups were improved， and more improvement was showen in the high-dose group. Compared with those in the blank group， the behavioral scores and peripheral blood total IgE levels of rats in the model group significantly increased， as well as the expression of TMEM16A， MUC5AC， and NF-κB proteins and mRNA in nasal mucosa （P＜0.05 or P＜0.01）. Compared with those in the model group， the behavioral scores and peripheral blood total IgE levels of rats in the high-dose Bimin Formula group decreased， and the expression of TMEM16A， MUC5AC， and NF-κB proteins and mRNA in nasal mucosaalso decreased （P＜0.05 or P＜0.01）； the behavioral scores and peripheral blood total IgE levels of rats in the low-dose Bimin Formula group were reduced， and the expression of TMEM16A and MUC5AC proteins and mRNA in nasal mucosa， as well as the expression of NF-κB protein decreased （P＜0.05 or P＜0.01）， but the difference in NF-κB mRNA expression was not statistically significant （P＞0.05）. Compared with the low-dose Bimin Formula group， the expression of NF-κB protein in the high-dose group decreased （P＜0.01）. ConclusionBimin Formula may improve the symptoms and high mucus secretion of AR lung-spleen qi deficiency by regulating the TMEM16A/NF-κB/MUC5AC signaling pathway in nasalmucosa.

Objective To evaluate the therapeutic effect of Huangqin Decoction(HQD)on ulcerative colitis(UC)in mice and explore its mechanism.Methods Male Balb/c mice were randomly divided into normal control group,model group,mesalazine group(5-ASA,200 mg/kg),and low-,medium-and high-dose HQD groups(2.275,4.55 and 9.1 g/kg,respectively).With the exception of those in the normal control group,all the mice were exposed to 3%DSS solution in drinking water for 7 days to establish UC models.After treatment with the indicated drugs,the mice were assessed for colon injury and apoptosis using HE,AB-PAS and TUNEL staining,and the expression levels of inflammatory factors were detected with ELISA.Western blotting,immunohistochemistry and qRT-PCR were used to detect the changes in protein expressions associated with the intestinal chemical barrier,mechanical barrier and endoplasmic reticulum stress(ERS).Results HQD treatment significantly reduced DAI score and macro score of UC mice,decreased colonic epithelial cell apoptosis,lowered expressions of IL-6,TNF-α,IL-1β and IL-8,and enhanced the expressions of MUC2 and TFF3.HQD treatment also upregulated the protein expressions of claudin-1,occludin and E-cadherin,reduced the expressions of GRP78,CHOP,caspase-12 and caspase-3,decreased the phosphorylation levels of PERK,eIF2α and IRE1α,and increased the Bcl-2/Bax ratio in the colon tissues of UC mice.Conclusion HQD inhibits colonic epithelial cell apoptosis and improves intestinal barrier function in UC mice possibly by reducing ERS mediated by the PERK and IRE1α signaling pathways.

Objective:To investigate the distribution patterns of TCM syndrome elements and syndrome types in cancer-related fatigue (CRF).Methods:A cross-sectional survey was conducted on tumor patients attending the outpatient clinic and wards of the Department of Oncology, Xiyuan Hospital of China Academy of Chinese Medical Sciences from January to December 2021. Descriptive analysis was used to compare the distribution difference of TCM syndrome elements, symptoms and tongue symptoms of CRF and non-CRF patients. The TCM symptoms of CRF were clustered to summarize the common TCM syndromes of CRF.Results:A total of 306 tumor patients were finally included, of which 229 (75%) were CRF and 77 (25%) were non-CRF. Qi deficiency, blood deficiency, and cold-dampness were the most common deficiency and excess syndrome elements in CRF, and liver deficiency, yin deficiency, and blood stasis syndrome elements occurred more frequently in non-CRF than in CRF. TCM symptoms with a frequency greater than 50% in CRF patients, from high to low, were: fatigue > shortness of breath > insomnia or dreaminess > mental fatigue > forgetfulness>lazy speech > impatience, irritability, depression with sighing. The most frequent tongue symptoms, tongue coating, and pulse symptoms were respectively pale tongue, white and greasy coating or smooth white, and pulse deficiency. The symptoms with greater than 30% frequency in 77 non-CRF patients were, from highest to lowest: impatience and irritability or depression with sighing > insomnia or dreaminess > shortness of breath > dry mouth and throat > lumbar spine pain (excluding traumatic) > numbness of limbs > forgetfulness. The highest-ranked tongue, tongue coating, and pulse symptoms were pale tongue, red tongue or less coating, no coating, and thin pulse, respectively. Through clustering analysis, six common syndromes of CRF were obtained, including qi and blood deficiency syndrome, heart and liver blood deficiency syndrome, kidney yang deficiency syndrome, qi and yin deficiency syndrome, spleen deficiency and qi stagnation syndrome, and cold dampness and spleen stagnation syndrome.Conclusions:CRF is a common symptom of different types of tumors. Generally, deficiency syndrome is the main symptom. Qi deficiency and blood deficiency are the common syndrome elements. Common symptoms of high frequency and tongue and pulse are fatigue, shortness of breath, mental fatigue, forgetfulness, pale tongue and thin pulse. The common TCM syndrome types can be preliminarily summarized into 6 types: qi and blood deficiency syndrome, heart and liver blood deficiency syndrome, kidney yang deficiency syndrome, qi and yin deficiency syndrome, spleen deficiency and qi stagnation syndrome, cold dampness and spleen stagnation syndrome.

Objective:To investigate the clinical features of pertussis in children and analyze the risk factors of severe pertussis.Methods:The clinical data of 248 children with pertussis hospitalized in Hunan Children′s Hospital from March 2018 to March 2022 were analyzed retrospectively.According to the age at admission, the patients were divided into two groups: ≤3 months and > 3 months.According to the patient′s condition, they were classified into ordinary group and severe group.According to the pathogens detected, the children were divided into single infection group and mixed infection group.The independent sample t-test, chi- square test were used to analyze the clinical indexes of the infants in above groups. Results:(1)Of 248 hospitalized children with pertussis, 204 cases (82.2%) were less than 1 year old, 92 cases (37.0%) had contact with a coughing family member before, and 169 cases (68.1%) were unvaccinated.Among 248 children, 193 cases (77.8%) had an elevated white blood cell count, and 145 cases (58.4%) had mixed infections.The most common pathogen was respiratory syncytial virus [29/248(11.6%)]. About 173 cases (69.7%) had concurrent pneumonia, and 35 cases (14.1%) had pulmonary consolidation.(2)Compared with the group > 3 months of age, more patients in the group ≤3 months of age had contact with a coughing family member before, and suffered from cyanosis, dyspnea, respiratory failure, heart failure and pertussis encephalopathy ( χ2=4.612, 20.810, 7.882, 16.617, 13.740, 7.846, all P<0.05). The proportions of patients in the group ≤3 months of age required intensive care unit(ICU) hospitalization and mechanical ventilation were higher than those in the group > 3 months of age ( χ2=14.810, 21.436, all P<0.05). The mortality of the group ≤3 months of age was higher than that of the group >3 months of age ( χ2=12.016, P<0.05). Children ≤3 months of age had a higher WBC level [(27.83±27.70)×10 9/L vs.(23.34±15.28)×10 9/L, t=22.244, P<0.001], longer duration of spasmodic cough [(16.56±9.33) d vs.(15.06±6.16) d, t=10.145, P=0.002] and longer hospitalization time [(11.47±10.48) d vs.(9.48±4.80) d, t=20.050, P<0.001] than those >3 months of age.(3)Compared with the ordinary group, a higher proportion of children in the severe pertussis group were under 3 months old, and had not been vaccinated against pertussis vaccine ( χ2=14.803, 4.475, all P<0.05). The ratio of patients with dyspnea, an lymphocyte count/neutral cell(LC/NC) ratio <1, mixed infections, lung consolidation and pleural effusion in the severe pertussis group was higher than that in the ordinary group ( χ2=116.940, 43.625, 13.253, 106.370, 11.874, all P<0.05). The patients in the severe pertussis group had a higher WBC [(61.66±29.63)×10 9/L vs.(18.83±10.00)×10 9/L, t=112.580, P<0.001] and a lower LC (0.494±0.186 vs.0.676±0.132, t=13.752, P<0.001) than those in the ordinary group.(4)Compared with the single infection group, the proportions of children with fever, dyspnea, fine moist lung rales, an LC/NC ratio <1, and lung consolidation were higher in the mixed infection group ( χ2=8.909, 6.804, 7.563, 8.420, 12.458, all P<0.05). More children in the mixed infection group required ICU hospitalization and mechanical ventilation than those in the single infection group ( χ2=11.677, 7.397, all P<0.05). The mixed infection group had higher respiratory failure and death rates than the single infection group ( χ2=7.980, 4.267, all P<0.05). Compared with the single infection group, the mixed infection group had a higher WBC level [(27.73±24.13)×10 9/L vs.(21.25±14.65)×10 9/L, t=13.318, P<0.001], longer hospitalization time [(11.593±9.010) d vs.(8.339±4.047) d, t=17.283, P<0.001], and a smaller LC ratio (0.626±0.165 vs.0.684±0.132, t=7.997, P=0.005). (5) Logistic regression analysis showed that age ≤3 months, peak WBC and dyspnea were risk factors of severe pertussis. Conclusions:Hospitalized pertussis children are prone to pneumonia and pulmonary consolidation.Patients aged ≤3 months with a large WBC and dyspnea easily develop into severe pertussis.Monitoring blood routine is helpful for judging the severity of the disease.Mixed infections increase the incidence of complications and can impair the treatment effect.

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Objective:To explore the characteristics of T lymphocyte subsets and cytokines in hyperlipidemia-induced acute pancreatitis (HLAP) and its prognostic value.Methods:This study included 184 patients with acute pancreatitis (AP) admitted to the First Affiliated Hospital of Xiamen University from January 2018 to May 2021. Based on disease etiology, there were 92 HLAP cases and 92 non-hyperlipidemia-induced AP (NHLAP) cases. Stratified by disease severity according to 2012 Atlanta classification criteria, the patients were divided into the severe subgroup (SAP) and non-severe subgroup (NSAP). Peripheral venous blood samples were taken from all patients on day 1, 3, and 5 after admission. T lymphocyte subsets were determined by flow cytometry, and cytokines were detected by flow fluorometry. The number of CD4 +% and CD8 +% and the expression of cytokines were compared by Student’s t test or Mann-Whitney U analysis. Logistic regression analyses were performed to identify risk factors for severe AP, and a receiver operating characteristic (ROC) curve was constructed to predict severe AP. Statistical significance was taken as P<0.05. Results:Compared with the NHLAP group, patients in the HLAP group had lower CD4 +%, while higher levels of IL-2 on day 1 ( P<0.05), and had also lower CD4 +%, while higher levels of IL-4, IL-6, and IL-10 on day 3 ( P<0.05). Furthermore, IL-6 and IL-10 levels of the HLAP group were significantly increased compared to the NHLAP group on day 5 ( P<0.05). IL-10 levels in the SAP subgroup were significantly higher than those in the NSAP subgroup on day 1 ( P<0.05). Compared with the NSAP subgroup, the SAP subgroup had elevated levels of IL-2, IL-4, IL-6, IL-10 and IFN-γ on day 3 (all P<0.05), and had lower CD4 +%, while increased levels of IL-6 and IL-10 on day 5 (all P<0.05). Multivariate Logistic regression analysis showed that IL-10 was an immune indicator of independent risk factor for severe AP in the HLAP group on day 1 ( OR=1.139, 95% CI: 1.038-1.251, P<0.05). Finally, ROC analysis showed that the area under the curve of IL-10 to assess HLAP with severe AP was 0.772, and the best cut-off value for predicting severe AP was 5.6 pg/mL, with a sensitivity of 83.3% and a specificity of 68.8%. Conclusions:Changes of CD4 +% and cytokines are different between the HLAP and NHLAP groups. IL-10 can be used as a predictor of early disease severity in patients with HLAP.

Objective To analyze the status of hepatitis B and BCG vaccination in children with special health status, and analyze the reasons for the delay of vaccination, so as to improve the timely vaccination rate. Methods A total of 1 129 children with special health status who were registered and vaccinated in our hospital from September 1, 2018 to January 23, 2020 were selected. All children were classified according to the major diseases based on the discharge records. The first injection time of hepatitis B and BCG vaccine was extracted, and the children were divided into different groups based on the number of people who delayed vaccination. The comparison between groups was performed by χ² test. Results A total of 87 children without hepatitis B vaccination and 85 children without BCG vaccination were immediately vaccinated in our hospital after the establishment of the archives in our hospital. None of the 1 129 children with special health status had serious adverse reactions after vaccination. The most common diseases in the delayed hepatitis B vaccination children were premature infants, cardiovascular diseases, and nervous system diseases. The most common diseases in the delayed BCG vaccination children were premature infants, cardiovascular diseases, and neonatal disease. There was a significant difference between the number of delayed hepatitis B vaccination and the number of delayed BCG vaccination, with the number of delayed BCG vaccination being more (χ²=278.24, P<0.00). Conclusion Delayed vaccinations are common in children with special health status. Normal vaccination does not increase the incidence of adverse reactions in children with special health status. Medical staff’s understanding of diseases, types of diseases, and types of vaccines are important factors affecting the vaccination of children with special health conditions. Support from social environment, the understanding and cooperation from children's parents and guardians, and the understanding of medical workers on vaccines and diseases are the keys to truly improve the vaccination rate of children..
