ObjectiveTo investigate the impact of anticentromere antibody （ACA） on the clinical features and prognosis of patients with primary biliary cholangitis （PBC） by comparing clinical classification， ursodeoxycholic acid （UDCA） response， GLOBE score， and UK-PBC score between ACA-positive PBC patients and ACA-negative PBC patients. MethodsA total of 749 patients who were admitted to Beijing Ditan Hospital， Capital Medical University， from August 2013 to December 2022 and were diagnosed with PBC were enrolled and divided into ACA-positive group with 147 patients and ACA-negative group with 602 patients. According to their conditions on admission， the two groups were compared in terms of the distribution of clinical types， i.e.， chronic progression-type PBC， portal hypertension-type PBC， and standard jaundice/liver failure-type PBC. There were 261 patients with complete data after 1-year follow-up， among whom there were 53 patients with positive ACA and 208 with negative ACA. A statistical analysis was performed， and propensity score matching was performed based on sex and age at a ratio of 1∶2. The two groups were compared in terms of 1-year UDCA response rate， GLOBE score， and UK-PBC score before and after matching. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. ResultsCompared with the ACA-negative group， the ACA-positive group had a significantly higher age （61.28±10.35 years vs 56.74±12.17 years， t=4.164， P<0.001）， a significantly higher proportion of female patients （93.9% vs 77.6%， χ²=20.221， P<0.001）， a significantly higher proportion of patients with portal hypertension （48.3% vs 27.6%， χ²=23.289， P<0.001）， and a significantly lower proportion of patients with jaundice/liver failure （24.5% vs 38.5%， χ²=10.205， P<0.001）. After 1-year follow-up， for the 261 PBC patients with complete data， there was no significant difference in UDCA response rate before propensity score matching between the ACA-positive group and the ACA-negative group （41.5% vs 41.8%， P>0.05）， and there was a significant difference in the proportion of patients with a GLOBE score of >0.3 between the ACA-positive group and the ACA-negative group （92.5% vs 80.3%， χ²=3.935， P=0.047）. There were 53 patients in the ACA-positive group and 106 patients in the ACA-negative group after propensity score matching， and there were no significant differences between the two groups in UDCA response rate， GLOBE score， and UK-PBC score （all P>0.05）. ConclusionACA-positive patients tend to have an older age， with a higher proportion of female patients or patients with portal hypertension， while there is a relatively low proportion of patients with jaundice/liver failure. Positive ACA has no significant impact on UDCA response rate， GLOBE score， and UK-PBC score.

ObjectiveTo observe the effect of Yulin Hukun decoction on autophagy mediated by phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway in the mouse model of cyclophosphamide-induced diminished ovarian reserve and explore the follicular development-improving mechanism of this decoction. MethodsSixty female ICR mice with normal estrous cycle were assigned into a blank group （n=10） and a modeling group （n=50）. The model was established by intraperitoneal injection of cyclophosphamide （60 mg·kg^-1） for 5 days. The successfully modeled mice were randomly grouped as follows： model， estradiol （0.26 mg·kg^-1）， and high-， medium-， and low-dose （56.42， 28.21， 14.105 g·kg^-1， respectively） Yulin Hukun decoction， with 10 mice in each group. The blank group and the model group received normal saline （10 mL·kg^-1）. The intervention was performed once a day for 21 days. The general conditions， estrous cycle， body weight， and ovary index were observed and recorded for each group. Serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， and anti-Müllerian hormone （AMH） were measured by enzyme-linked immunosorbent assay. Histopathological changes in the ovarian tissue were observed by hematoxylin-eosin staining. Western blot was employed to determine the protein levels of PI3K， Akt， mTOR， autophagy-related protein 7 （Atg7）， beclin1， microtubule-associated protein 1 light chain 3Ⅱ （LC3Ⅱ）， ubiquitin-binding adaptor protein （p62）， forkhead box protein O1 （FoxO1）， and acetylated forkhead box protein O1 （Ac-FoxO1） in mouse ovaries. Real-time PCR was adopted to determine the mRNA levels of PI3K， Akt， mTOR， Atg7， beclin1， and LC3Ⅱ in the mouse ovarian tissue. ResultsCompared with the blank group， the model group had disturbed estrous cycle， decreased body weight （P<0.05）， loose ovarian structure with increased atretic follicles， increased serum FSH level （P<0.05）， and decreased AMH and estradiol levels （P<0.05）. Compared with the model group， the treatment groups showed recovered estrous cycles and body weight. The estradiol group and high- and medium-dose Yulin Hukun decoction groups showed declined FSH level （P<0.05） and elevated AMH levels （P<0.05）. In addition， the treatment groups showed downregulated protein levels of Atg7， LC3Ⅱ， beclin1， FoxO1， and Ac-FoxO1 （P<0.01）， upregulated protein levels of PI3K， Akt， mTOR， and p62 （P<0.01） in the ovarian tissue， gradual repair of the ovarian structure， with more intact and numerous follicles of various stages. ConclusionYulin Hukun decoction can inhibit autophagy in ovarian granulosa cells by activating the PI3K/Akt/mTOR signaling pathway and inhibiting the expression of autophagy-related proteins and transcription factors， thereby improving follicular development and ovarian reserve.

ObjectiveTo observe the effect of Banxia Xiexintang （BXT） on the proliferation of human gastric cancer HGC-27， MKN-45， and AGS cells and its mechanism. MethodCell counting kit-8 （CCK-8） was used to detect the effects of different concentrations of BXT-containing serum （5%， 10%， and 20%） on the proliferation of HGC-27， MKN-45， and AGS cells. A mitochondrial membrane potential probe （TMRE） was used to detect the expression of mitochondrial membrane potential in cells. A kit was used to detect iron ion （Fe²⁺） content， lipid peroxide （LPO）， and superoxide dismutase （SOD） activity. Western blot was used to detect the protein expression levels of glycogen synthase3β （GSK3β）， phosphorylated GSK3β （p-GSK3β）， nuclear factor E₂ related factor 2 （Nrf2）， and glutathione peroxidase 4 （GPX4）. The real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of member 11 of the cystine/glutamic acid reverse transporter solute vector family 7 （SLC7A11）， member 2 of the heavy chain solute vector family 3 （SLC3A2）， transferrin receptor 3 （TFRC）， and tumor protein （TP）53. ResultCCK-8 results showed that BXT and capecitabine could significantly reduce the survival rate of three kinds of gastric cancer cells after treatment with drug-containing serum for 24 h （P<0.01）. After 48 h of intervention with drug-containing serum， the survival rate of three kinds of gastric cancer cells was significantly decreased in both the capecitabine group and the BXT group compared with the blank group. The BXT group was dose-dependent， with 20% BXT having the most significant effect （P<0.01）. In terms of biochemical indicators of ferroptosis， compared with the blank group， BXT and capecitabine significantly decreased the expression of mitochondrial membrane potential （P<0.01） and SOD activity （P<0.01） and significantly increased the contents of LPO and Fe²⁺ （P<0.01）， so as to improve the sensitivity of gastric cancer cells to ferroptosis. In terms of the Nrf2/GPX4 pathway， compared with the blank group， the BXT group could reduce the protein expressions of p-GSK3β， Nrf2， and GPX4 （P<0.01） in gastric cancer cells and increase mRNA expressions of SLC7A11 and SLC3A2 （P<0.05）. It could also increase the protein expression of GSK3β （P<0.01） and mRNA expression of TP53 and TFRC （P<0.05， P<0.01） in gastric cancer cells. Inhibition of the Nrf2/GPX4 pathway induces ferroptosis in gastric cancer cells. Compared with the capecitabine group， the 20% BXT group showed a more obvious effect. ConclusionBanxia Xiexintang can induce ferroptosis in gastric cancer cells HGC-27， MKN-45， and AGS by inhibiting the Nrf2/GPX4 pathway.

Objective:To analyze the status quo and influencing factors of post-traumatic growth of parents of children and adolescents with type 1 diabetes mellitus (T1DM) .Methods:The convenient sampling method was used to select parents of children with T1DM who were admitted to the diabetes care consultation clinic of Beijing Children's Hospital, Capital Medical University from March 2022 to March 2023 as the research objects. The parents of children were investigated by general information questionnaire, Posttramnatic Growth Inventory, Simplified Coping Style Questionnaire and Perceived Social Support Scale.Results:A total of 200 questionnaires were sent out in this study, and 187 were effectively collected, with an effective recovery rate of 93.5% (187/200). The total score of Posttramnatic Growth Inventory for parents of T1DM children was (60.28±18.37). The positive coping score in Simplified Coping Style Questionnaire was (22.40±6.94) and the negative coping score was (8.94±4.58). The total score of Perceived Social Support Scale was (57.39±14.57). The results of multiple linear regression analysis showed that HbA1c, monthly family income, educational level, positive coping strategies and perceived social support were the influencing factors for the post-traumatic growth of parents of T1DM children, explaining 33.8% of the variation in post-traumatic growth of parents of T1DM children.Conclusions:The post-traumatic growth of parents of T1DM children is at a moderate level. Medical staff should pay more attention to parents of children with poor blood sugar control, low educational level and low monthly family income, guide them from the perspective of positive psychology, encourage parents to adopt positive and effective coping strategies and emphasize the importance of social support, so as to improve the level of post-traumatic growth of parents of children with T1DM.

Objective To investigate the changes of coagulation,fibrinolysis and platelet indexes in ovarian cancer patients before and after neoadjuvant chemotherapy,and to analyze the risk relationship between relevant indexes before treatment and the effect of neoadjuvant chemotherapy(NACT).Methods Patients with ovarian cancer admitted to Xi'an Fengcheng Hospital,from March 2020 to March 2023 were included as the ovarian cancer group,and female patients who underwent physical examination in the same period were selected as the control group according to a 2∶1 ratio.Prothrombin time(PT),thrombin time(TT),activated partial thromboplastin time(APTT),fibrinogen(FIB),platelet distribution width(PDW),platelet hematocrit(PCT),platelet(PLT)and mean platelet volume(MPV)were compared between the two groups.The changes of these indexes were compared before and after NACT,at different clinical stages and before and after NACT with different efficacy effects.Moreover,they were divided into effective and ineffective groups according to their treatment efficacy.Logistic regression was used to explore the relationship between the parameters and NACT efficacy;receiver operating characteristic curve was drawn to predict the value of NACT efficacy.Results A total of 144 patients were included,with 96 cases in the ovarian cancer group and 48 in the control group.The FIB,PLT and MPV of patients in the ovarian cancer group were higher than those in the control group(P<0.05).The PT,TT,APTT,FIB and PLT of ovarian cancer patients after NACT were lower than those before NACT(P<0.05).FIB and PLT of stage Ⅱ patients were lower than those of stage Ⅲ before and after NACT,and the PT,TT,APTT,FIB and PLT of the effective group were lower than those of the ineffective group before and after NACT,and the PT,TT,APTT,FIB and PLT of the two groups after NACT were lower than those before NACT(P<0.05).Multivariate Logistic regression analysis indicated that high PT,TT,APTT,FIB and PLT before NACT were independent risk factors for NACT ineffectiveness(P<0.05).The area under the curve of PT,TT,APTT,FIB and PLT before NACT to predict the effect of NACT were 0.713(sensitivity of 80.95%,specificity of 69.33%),0.756(sensitivity of 71.43%,specificity of 82.67%)and 0.787(sensitivity of 76.19%,specificity of 70.67%),0.727(sensitivity of 71.43%,specificity of 84.00%),0.794(sensitivity of 80.95%,specificity of 76.00%),respectively.Conclusion Changes in coagulation and fibrinolytic function and platelet parameters in ovarian cancer patients after NACT are associated with clinical stages and NACT effect.High levels of PT,TT,APTT,FIB and PLT before NACT are important reasons affecting NACT effect.Constructing the risk prediction model of NACT efficacy in ovarian cancer patients based on the above five parameters can provide a reference for clinical practice.
