Objective:The purpose of this study was to explore the critical values of monitored indexes of perioperative major adverse cardiac events(MACE), so as to take effective prevention and treatment measures in time to maintain the stability of perioperative cardiac function to further improve the perioperative safety of elderly patients with biliary diseases.Methods:The clinical data of 246 elderly patients with biliary diseases in our hospital from May 2016 to February 2022 were collected.According to whether MACE occurred during the perioperative period, they were divided into the MACE group and the non-MACE group.The differences of clinical data, the monitoring indexes of postoperative cardiac function, and the coagulation function between the two groups were compared and analyzed.Logistic regression was used to analyze the independent risk factors of perioperative MACE, the cut-off value of the receiver operating characteristic(ROC)curve was calculated, and the Logistic multivariate prediction model was established.Results:In the MACE compared with the non-MACE group, age, postoperative complications and mortality, postoperative hospital stay, and the levels of postoperative high sensitivity troponin-I(Hs-TnI), creatine kinase isoenzyme(CK-MB), myoglobin(MYO), B-type natriuretic peptide(BNP), and D-dimer(D-D)were significantly increased(all P<0.05). Multivariate Logistic regression showed that postoperative BNP and D-D were two independent risk factors for perioperative MACE, and their cut-off values in the ROC curve were 382.65 pg/mL and 0.975mg/L respectively.The Logistic multivariate prediction model established by the Logistic regression equation was P= ex/(1+ ex), X=-5.710+ 0.003X 1+ 0.811X 2, where X 1 was the postoperative BNP level and X 2 was the postoperative D-D level.The accuracy, specificity and sensitivity of this prediction model for predicting perioperative MACE were 96.3%(237/246), 100.0%(235/235), and 18.2%(2/11). Conclusions:The Logistic multivariate prediction model established in this study can effectively predict the occurrence of perioperative MACE in elderly patients.Postoperative BNP and D-D were two independent risk factors for perioperative MACE.The cut-off values of BNP and D-D in the ROC curve could be used as critical values for monitoring perioperative MACE.Therefore, it is of great clinical significance to take effective prevention and treatment measures in time to maintain the stability of perioperative cardiac function, and further improve the perioperative safety of elderly patients with biliary diseases.

Aim To investigate whether notoginsenoside Rl (PNS-R1) alleviates allergic rhinitis (AR) through AMP-activated protein kinase (AMPK)/mitochondrial fission critical protein (DRP1) -mediated mitochondrial fission. Methods Different doses of PNSRl were used to treat ovalbumin (OVA) -induced AR model mice,and the inhibitory effect of PNS-R1 on AR was investigated by observing allergic symptoms such as nasal rubbing and sneezing, as well as HE staining of nasal tissues. Serum IgE levels and nasal lavage fluid (NLF) inflammatory cytokine levels were detected by enzyme-linked immunosorbent assay (ELISA) and apoptosis-related proteins were detected by Western blot. In vitro human nasal epithelial cells (HNEpC) were stimulated with IL-13 to observe apoptosis, mitochondrial membrane potential, cellular ROS and mitochondrial ROS production, as well as the expression levels of AMPK/DRP1, expression levels of the TXNIP/NLRP3 inflammasomes and the translocation of DRP1. Results PNS-R1 attenuated allergic symptoms in AR mice, HE staining reduced inflammatory cells and reduced the levels of OVA-specific IgE in serum, and the levels of IL-4, IL-6, and IL-8 in NLF. PNS-R1 attenuated the apoptosis and ROS production of nasal epithelial cells in AR. In vitro PNS-R1 could up-regulate mitochondrial membrane potential after IL-13 stimulation, reduce ROS and mtROS production, the proportion of apoptotic positive cells, and reduce cleaved caspase-3, Bax, and up-regulate Bcl-2 expression, down-regulate DRP1 phosphorylation (Ser 616) and DRP1 translocation at the mitochondrial membrane in an AMPK-dependent manner, reducing TXNIP/NLRP3 expression. Conclusions PNS-R1 can protect mitochondrial integrity by inhibiting the AMPK/DRP1 signaling axis and its subsequent TXNIP/NLRP3 signaling axis,thereby alleviating rhinitis in AR mice.

Objective To investigate the protective effect and mechanism of polydatin ( PD) on allergic rhinitis (AH) by regulating mitophagy through PINK1- Parkin signaling pathway, and to provide a new target for clinical treatment of AH.Methods Thirty-two BALB/c murine were randomly divided into 4 groups: control group, OVA group, PD low-dose (30 mg • kg 1 ) and high-dose ( 45 mg • kg 1 ) treatment groups.At the end of modeling, the total number of sneezing and nasal nibbing of murine was recorded.HE staining was used to observe the morphology of na- sal mucosal epithelium and eosinophil infiltration.Western blot was used to detect the expression of P1NK1 , Parkin, TOM20 and mitochondrial apoptosis- related proteins Bax, Bcl-2, caspase-3, cleaved- caspase-3 and Cytochrome C.Hie expression of P1NK1 and cleaved-caspase-3 in nasal epithelial cells (HNEpC) was observed by immunofluorescence.Re¬sults The frequency of sneezing and nasal rubbing movements was significantly increased, the nasal mu¬cosa epithelium was thickened, and eosinophils were accumulated in AH murine , these results were reversed after PD treatment.Western blot results shower] that signaling proteins PINK1/Parkin anrl pro-apoptotie pro¬teins, including Bax, caspase-3, cleaved-caspase-3 and Cytochrome C were significantly overexpressed, the expression of TOM20 and Bcl-2 was decreased in OVA group, and PD up-regulated the levels of P1NK1 , Parkin, as well as Bcl-2 and inhibited the expression of TDM20 and pro-apoptotic proteins, while after pre- treatment with mitochondrial division inhibitor 1 ( Mdi- vi-1 ) , the expression of P1NK1 and Parkin was re¬duced , the expression of TOM20 was increased, while PD treatment did not significantly affect this effect.From the immunofluorescence results, it can be seen that the level of P1NK1 was increased after IL-13 stim¬ulation of HNEpCs compared with the control group, and PD further up-regulated the expression of P1NK1 , which was suppressed after pretreatment with Mdivi-1 , while PD did not change this phenomenon.Western blot results for P1NK1 and cleaved-caspase-3 were con¬firmed by immunofluorescence.Conclusion PD may activate mitophagy through the P1NK1 -Parkin signaling pathway, thereby protecting against AR.

Although there is guidance from different regulatory agencies, there are opportunities to bring greater consistency and stronger applicability to address the practical issues of establishing and operating a data monitoring committee (DMC) for clinical studies of Chinese medicine. We names it as a Chinese Medicine Data Monitoring Committee (CMDMC). A panel composed of clinical and statistical experts shared their experience and thoughts on the important aspects of CMDMCs. Subsequently, a community standard on CMDMCs (T/CACM 1323-2019) was issued by the China Association of Chinese Medicine on September 12, 2019. This paper summarizes the key content of this standard to help the sponsors of clinical studies establish and operate CMDMCs, which will further develop the scientific integrity and quality of clinical studies.

BACKGROUND: The neoadjuvant chemotherapy is increasingly used in advanced gastric cancer, but the effects on safety and survival are still controversial. The objective of this meta-analysis was to compare the overall survival and short-term surgical outcomes between neoadjuvant chemotherapy followed by surgery (NACS) and surgery alone (SA) for locally advanced gastric cancer. METHODS: Databases (PubMed, Embase, Web of Science, Cochrane Library, and Google Scholar) were explored for relative studies from January 2000 to January 2021. The quality of randomized controlled trials and cohort studies was evaluated using the modified Jadad scoring system and the Newcastle-Ottawa scale, respectively. The Review Manager software (version 5.3) was used to perform this meta-analysis. The overall survival was evaluated as the primary outcome, while perioperative indicators and post-operative complications were evaluated as the secondary outcomes. RESULTS: Twenty studies, including 1420 NACS cases and 1942 SA cases, were enrolled. The results showed that there were no significant differences in overall survival (P = 0.240), harvested lymph nodes (P = 0.200), total complications (P = 0.080), and 30-day post-operative mortality (P = 0.490) between the NACS and SA groups. However, the NACS group was associated with a longer operation time (P < 0.0001), a higher R0 resection rate (P = 0.003), less reoperation (P = 0.030), and less anastomotic leakage (P = 0.007) compared with SA group. CONCLUSIONS Compared with SA, NACS was considered safe and feasible for improved R0 resection rate as well as decreased reoperation and anastomotic leakage. While unbenefited overall survival indicated a less important effect of NACS on long-term oncological outcomes.

BACKGROUND: Epithelial to mesenchymal transition (EMT) is strongly linked with tumor invasion and metastasis, which performs a vital role in carcinogenesis and cancer progression. Emerging evidence suggests that microRNAs (miRNAs) expression are closely associated to EMT by regulating targeted genes. MiR542 has been found to be involved in the EMT program and bound up with various cancers. However, the functions of miR542 and its underlying mechanism in glioblastoma multiforme (GBM) remain largely unknown. In the current study, we investigated the effect of astrocyte elevated gene-1 (AEG-1) on U251 cells aggressiveness, proliferation, apoptosis, and cell cycle. METHODS: The screening of targeted miRNAs was performed, as well as the functional roles and mechanisms of miR542 were explored. RESULTS: MiR542 was selected as the target because of the most significantly differential expression and this high level of expression negatively correlated with cell migration and proliferation, which suggested that miR542 could be a novel tumor suppressor. Moreover, we confirmed that AEG-1 was a direct targeted gene of miR542 by luciferase activity assay, reverse transcription-polymerase chain reaction, and immunoblotting analysis. Furthermore, miR542 suppressed the expression of AEG-1, which upgraded the level of E-cadherin and degraded Vimentin expression contributing to retraining EMT. CONCLUSION The in vitro findings demonstrated that miR542 inhibited the migration and proliferation of U251 cells and suppressed EMT through targeting AEG-1, indicating that miR542 may be a potential anti-cancer target for GBM.
