ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Objective To investigate the effect and mechanism of lycium barbarum polysaccharide(LBP)on hepatocyte injury induced by homocysteine(Hcy).Methods Normal C3H/An mouse hepatocytes(NCTC 1469)were cultured in vitro and treated with different concentrations of Hcy(0,50,100,200,500 μmol/L).The optimal concentrations of Hcy-treated NCTC 1469 cells were detected by MTT assay.When the cells reached the logarithmic growth stage,the conditions were set up as follows:(1)control group(cultured with DMEM medium supplemented with 10%horse serum)and Hcy group(treated with 100 μmol/L Hcy solution for 48 h),and the cells were collected.Cell viability staining was used to detect apoptosis,aspartate aminotransferase(AST)/alanine aminotransferase(ALT)activity detection kit was used to detect AST and ALT activities,RT-qPCR was used to detect the expression levels of YAP1,DNMT1,DNMT3a and DNMT3b mRAN,and Western blotting was used to detect the expression of YAP1 protein,nested methylation specific PCR(nMS-PCR)was used to detect DNA methylation rates in the YAP1 promoter region.(2)Control group,LBP group,Hcy group and Hcy+LBP group.LBP group was treated with 4 mg/ml LBP solution for 2 h,Hcy group and Hcy+LBP group were treated with 100 μmol/L Hcy solution for 48 h,and Hcy+LBP group was treated with 4 mg/ml LBP solution at 46 h,and the cells were collected.The expression levels of YAP1,DNMT1,DNMT3a and DNMT3b mRAN were detected by RT-qPCR;the expression of YAP1,Bax and Bcl-2 proteins was detected by Western blotting;AST/ALT activity detection kit was used to detect AST and ALT activities.Prediction of DNA methylation CpG islands in YAP1 promoter region by bioinformatics.Results NCTC 1469 cells were treated with 100 μmol/L Hcy according to the results of MTT assay.Compared with control group,the apoptosis rate of Hcy group increased(P<0.01),the activities of ALT and AST increased(P<0.001),the mRAN and protein expression levels of YAP1 decreased(P<0.001),and the methylation rate of YAP1 promoter region increased(P<0.01),the mRNA expression levels of DNMT1,DNMT3a and DNMT3b increased(P<0.01 or P<0.001).Compared with Hcy group,the mRNA expression levels of DNMT1,DNMT3a and DNMT3b in the Hcy+LBP group decreased(P<0.001),the mRAN and protein expression levels of YAP1 significantly increased(P<0.01 or P<0.001).In addition,in the Hcy+LBP group,cells showed significantly elevated of Bcl-2 protein(P<0.001),but decreased Bax protein(P<0.001),and decreased activities of ALT and AST(P<0.001).Conclusions The decrease of YAP1 expression may be the key process of Hcy induced injury of NCTC 1469 cells,and the methylation of the YAP1 promoter region may be the molecular mechanism of Hcy induced YAP1 expression change.LBP may improve NCTC 1469 cell damage induced by Hcy by positively regulating YAP1 expression.

Objective:Analyzed the clinicopathological features of thymoma with alopecia areata, and discussed the pathogenesis and treatment methods.Methods:The clinicopathologic data of patients with thymoma who underwent surgery from August 1, 2015 to July 31, 2020 in Beijing Tongren Hospital, Capital Medical University were reviewed. Transversally analyzed the patients of thymoma with alopecia areata and longitudinally compared with the patients of thymoma without alopecia areata after 1﹕10 matched by propensity score matching.Results:A total of 252 patients of thymoma were enrolled, including 6 patients with alopecia areata, accounting for 2.38%. The anti-AchR antibody, CD4 + /CD8 + T inversion in serum and myasthenia gravis were present in the all 6 thymoma patients with alopecia areata, which were significantly higher than those in the group of thymoma without alopecia areata. Besides myasthenia gravis, the proportion of complicated with other autoimmune diseases in thymoma patients with alopecia areata was significantly higher than that of thymoma patients without alopecia areata[83.33%(5/6) vs. 20.00%(12/60), P=0.003]. After operation, 5 patients’ alopecia areata were improved in 6 thymoma patients with alopecia areata(83.33%, 5/6). Conclusion:The thymoma patients with alopecia areata always complicated with myasthenia gravis and other autoimmune diseases. The pathogenesis may be associated with autoimmune CD8 + T lymphocytes produced by thymoma. At present, surgery is still the most effective way to improve thymoma-associated alopecia areata.

ObjectiveTo explore the therapeutic mechanism of Bushen Huoxue prescription from the perspective of bone metabolism by observing the clinical efficacy of this prescription in treating femoral head necrosis （ONFH， syndrome of liver and kidney deficiency） and its influences on bone metabolism indexes： N-terminal propeptide （PINP） and β-collagen degradation product （β-CTX）. MethodSixty-six ONFH patients with the syndrome of liver and kidney deficiency in Zhengzhou Traditional Chinese Medicine Hospital of Orthopedics from December 2021 to September 2022 were selected. The patients were randomized into an experimental group and a control group by the parallel control method， with 33 patients in each group. The experimental group received Bushen Huoxue prescription orally， while the control group received Xianlinggubao Capsules orally， with a treatment cycle of 6 months. The visual analogue scale （VAS） score， Harris score， Association Research Circulation Osseous （ARCO） staging， imaging changes， quantitative scores of TCM symptoms， and serum levels of PINP and β-CTX were determined before and after treatment. The occurrence of adverse events and reactions was recorded. ResultThe total response rate in the experimental group was 83.87% （26/31）， which was higher than that （68.75%， 22/32） in the control group （Z=-2.096， P<0.05）. After treatment， the single and total scores of TCM symptoms， VAS score， and β-CTX level decreased in the two groups （P<0.05）. Moreover， the decreases in the scores of hip pain， lower limb mobility， soreness of waist and knees， and lower limb flaccidity， total score of TCM symptoms， VAS score， and β-CTX level in the experimental were larger than those in the control group （P<0.05）. After treatment， the imaging results showed no significant improvement in the two groups. The Harris score and PINP level in both groups increased after treatment （P<0.05）， and the increases were more obvious in the experimental group than in the control group （P<0.05）. No serious adverse event or adverse reaction appeared during the observation period. ConclusionBushen Huoxue prescription can relieve pain and TCM symptoms and improve the hip joint function in treating ONFH patients with the syndrome of liver and kidney deficiency. It can inhibit the development of ONFH， increase PINP， and decrease β-CTX. No obvious side effect appears during the clinical observation period， which shows that Bushen Huoxue prescription has good safety.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.
