【Objective】 To investigate the clinical application of heparinase-modified TEG (hmTEG) in evaluating coagulation status and monitoring anticoagulant therapy in severe non-ICU patients with COVID-19. 【Methods】 The clinical data of severe non-ICU patients with COVID-19 confirmed to be infected with novel coronary disease (SARS-CoV-2) from December 2022 to May 2023 were analyzed retrospectively. The patients were divided into therapeutic dose group and prophylactic dose group according to the initial dose of enoxaparin. The changes of platelet count, activated partial thromboplastin time, prothrombin time, thrombin time, fibrinogen, D-dimer, TEG and hmTEG before and after heparin treatment were compared between the two groups, so as to evaluate the changes of coagulation function and bleeding risk of COVID-19 severe non-ICU patients after anticoagulation with different doses of heparin. 【Results】 A total of 179 severe non-ICU patients with COVID-19 were enrolled in this study, including 102 patients in therapeutic dose group and 77 patients in prophylactic dose group. Before receiving heparin anticoagulation, except for age(63.4±11.6 vs 59.8±9.1) D-dimer(678 ng/mL vs 621 ng/mL) and MA values [(69.1±10.2)mm vs (65.6±8.5)mm], there were no statistical differences in platelet count, activated partial thromboplastin time, prothrombin time, thrombin time, fibrinogen, R value, K time, α angle and coagulation index (CI) between the therapeutic dose group and the prophylactic dose group (P>0.05). After receiving heparin anticoagulation, there were significant differences in CKR value [(12.2±4.1)min vs (10.2±3.3)min] and CKHR value [(8.1±3.2)min vs (7.1±2.6)min] between therapeutic dose group and prophylactic dose group (P0.05). Meanwhile, the proportion of heparin overdose in the therapeutic dose group was significantly higher than that in the prophylactic dose group 15.69%(16/102) vs 5.19%(4/77)(P0.05). 【Conclusion】 In the current epidemic trend of COVID-19, in order to reduce the occurrence of bleeding events, the heparin dose should be selected more carefully in the prevention of thrombosis in severe non-ICU patients with COVID-19. The individualized assessment of bleeding risk by hmTEG is more conducive to the adjustment and control of heparin dose.

Objective:To investigate the relationship between age-adjusted Charlson comorbidity index (aCCI) and ischemic stroke in patients with ophthalmic artery occlusion (OAO) or retinal artery occlusion (RAO).Methods:A single center retrospective cohort study. Seventy-four patients with OAO or RAO diagnosed by ophthalmology examination in Shenzhen Second People's Hospital from June 2004 to December 2020 were included in the study. The baseline information of patients were collected and aCCI was used to score the patients' comorbidity. The outcome was ischemic stroke. The median duration of follow-up was 1 796.5 days. According to the maximum likelihood ratio of the two-piecewise COX regression model and the recursive algorithm, the aCCI inflection point value was determined to be 6, and the patients were divided into low aCCI group (<6 points) and high aCCI group (≥6 points). A Cox regression model was used to quantify the association between baseline aCCI and ischemic stroke.Results:Among the 74 patients, 53 were males and 21 were females, with the mean age of (55.22±14.18) (19-84) years. There were 9 patients of OAO and 65 patients of RAO. The aCCI value ranges from 1 to 10 points, with a median of 3 points. There were 63 patients (85.14%, 63/74) in the low aCCI group and 11 patients (14.86%, 11/74) in the high aCCI group. Since 2 patients could not determine the time from baseline to the occurrence of outcome events, 72 patients were included for Cox regression analysis. The results showed that 16 patients (22.22%, 16/72) had ischemic stroke in the future. The baseline aCCI in the low aCCI group was significantly associated with ischemic stroke [hazard ratio ( HR)=1.76, 95% confidence interval ( CI) 1.21-2.56, P=0.003], and for every 1 point increase in baseline aCCI, the risk of future ischemic stroke increased by 76% on average. The baseline aCCI in the high aCCI group had no significant correlation with the ischemic stroke ( HR=0.66, 95% CI 0.33-1.33, P=0.247). Conclusions:aCCI score is an important prognostic information for patients with OAO or RAO. A higher baseline aCCI score predicts a higher risk of ischemic stroke, and the association has a saturation effect.

AIM: To scrutinize the role of the Wnt/β-catenin signaling pathway in the epithelial-mesenchymal transition(EMT)of lens epithelial cells under hypoxic conditions, and to further analyze the effect of Dickkopf-1(DKK-1)expression on EMT of lens epithelial cells.METHODS: Human lens epithelial cells(HLEB3 cells)were propagated in vitro and then separated into two groups: one exposed to standard oxygen levels, added DMEM culture solution containing 10% FBS(normoxic group)and another subjected to low oxygen levels(hypoxic group). The hypoxic condition was emulated by applying a concentration of 100 μmol/L cobalt chloride(CoCl2)for 6, 12, 24, and 48h. The utilization of immunofluorescence staining enabled the detection of Wnt3a and DKK-1 expressions, along with the expression and localization of β-catenin protein in these groups. The expression of DKK-1 mRNA was discerned by quantitative real-time polymerase chain reaction(qRT-PCR).RESULTS: Immunofluorescence assays indicated an escalating trend in the Wnt3a and DKK-1 protein expression, which corresponded with the increasing duration of hypoxia. Likewise, an intensified nuclear accumulation of β-catenin protein was observed to be directly proportional to the length of hypoxia treatment. The qRT-PCR demonstrated that the difference in DKK-1 mRNA expression between the normoxic group and the group exposed to hypoxia for 6h was not statistically significant(P>0.05), whereas the DKK-1 mRNA expression of the 12, 24, and 48h hypoxia groups were significantly increased(P<0.001).CONCLUSION: Hypoxia can activate Wnt/β-catenin pathway in lens epithelial cells and induce the expression of DKK-1, thus regulating the Wnt/β-catenin pathway and affecting the EMT process.

摘要
This study aimed to investigate the effects of nanoparticles PLGA-NPs and mesoporous silicon nanoparticles(MSNs) of different stiffness before and after combination with menthol or curcumol on the mechanical properties of bEnd.3 cells. The particle size distributions of PLGA-NPs and MSNs were measured by Malvern particle size analyzer, and the stiffness of the two nanoparticles was quantified by atomic force microscopy(AFM). The bEnd.3 cells were cultured in vitro, and the cell surface morphology, roughness, and Young's modulus were examined to characterize the roughness and stiffness of the cell surface. The changes in the mechanical properties of the cells were observed by AFM, and the structure and expression of cytoskeletal F-actin were observed by a laser-scanning confocal microscope. The results showed that both nanoparticles had good dispersion. The particle size of PLGA-NPs was(98.77±2.04) nm, the PDI was(0.140±0.030), and Young's modulus value was(104.717±8.475) MPa. The particle size of MSNs was(97.47±3.92) nm, the PDI was(0.380±0.016), and Young's modulus value was(306.019±8.822) MPa. The stiffness of PLGA-NPs was significantly lower than that of MSNs. After bEnd.3 cells were treated by PLGA-NPs and MSNs separately, the cells showed fine pores on the cell surface, increased roughness, decreased Young's modulus, blurred and broken F-actin bands, and reduced mean gray value. Compared with PLGA-NPs alone, PLGA-NPs combined with menthol or curcumol could allow deepened and densely distributed surface pores of bEnd.3 cells, increase roughness, reduce Young's modulus, aggravate F-actin band breakage, and diminish mean gray value. Compared with MSNs alone, MSNs combined with menthol could allow deepened and densely distributed surface pores of bEnd.3 cells, increase roughness, reduce Young's modulus, aggravate F-actin band breakage, and diminish mean gray value, while no significant difference was observed in combination with curcumol. Therefore, it is inferred that the aromatic components can increase the intracellular uptake and transport of nanoparticles by altering the biomechanical properties of bEnd.3 cells.

This study established a mouse model of ulcerative colitis and explored the serum transitional components of Gegen Qinlian Decoction by UHPLC-Q-Orbitrap-MS. Based on the exact relative molecular weight and MS/MS spectrum, 55 prototype components and 59 metabolites were identified from the model group, while 18 prototype components and 35 metabolites from the control group. The prototype components in serum were mainly flavonoids and the characteristic components of the model group were alkaloids. Glucuronidation, sulfonation, and glycosylation have been confirmed to be the main metabolic types in vivo. The results of comparative analysis of differences indicated that puerarin, baicalin, wogonoside, wogonin, chrysin, oroxylin A, berberine, berberrubine, and palmatine were the characteristic components in model state, which at the same time, were confirmed by pharmacological studies to be the serum pharmacodynamic material basis of Gegen Qinlian Decoction in the treatment of ulcerative colitis. This study has provided reference for explaining the metabolic transformation pattern and mechanism of action of Gegen Qinlian Decoction in vivo.

Objective:To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China.Methods:Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use.Results:Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol ( OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol ( OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased ( OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased ( OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant ( P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient ( P<0.01). Conclusion:For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

Objective:To explore the effect of postoperative delirium risk management in elderly patients with hip fragility fracture based on failure mode and effect analysis (FMEA) theory, and to provide a basis for reducing the incidence of postoperative delirium.Methods:A total of 50 patients admitted to the First Affiliated Hospital of Sun Yat-sen University due to hip fragility fractures from January to December 2019 were selected as the control group, and 50 patients admitted to the First Affiliated Hospital of Sun Yat-sen University for hip fragility fractures from January to December 2020 were selected as the observation group. The control group received routine care, and the observation group implemented risk control intervention measures based on FMEA theory on the basis of the control group. The risk priority number (RPN) value, incidence of delirium, duration of delirium, pain score, satisfaction, and average length of hospital stay were compared between the two groups of patients in each link of failure risk.Results:The RPN values of each link failure risk of the observation group were 100.80 ± 13.39, 103.96 ± 9.96, 103.76 ± 8.04, delirium duration was (36.33 ± 9.07) min, pain scores were 1.86 ± 0.76, 4.16 ± 1.17, average length of stay was (8.98 ± 4.64) days, and incidence of delirium was 6.0% (3/50), the RPN values of each link failure risk of the control group were 274.10 ± 8.48, 291.00 ± 10.10, 287.78 ± 11.64, delirium duration (78.70 ± 20.10) min, pain scores 2.26 ± 1.02, 4.74 ± 1.19, average length of stay was (11.50 ± 7.66) days, and incidence of delirium was 22.0% (11/50). The differences between two groups showed significant differences ( t values were 1.99-93.24, χ2=4.07, P<0.05). The patient satisfaction score of the observation group was 99.36 ± 1.01, which was higher than that of the control group 89.63 ± 2.62, and the difference was statistically significant ( t=24.50, P<0.05). Conclusions:The perioperative implementation of postoperative delirium risk management model based on FMEA theory in elderly patients with hip fractures can reduce the incidence of postoperative delirium, relieve pain, shorten hospital stay, and improve satisfaction degree. It is worthy of clinical promotion.

Objective:To explore the value of "conceive, design, implement, and operation" (CDIO) combined with cluster training mode in clinical teaching of cardiopulmonary resuscitation (CPR).Methods:A total of 108 interns of General Hospital of Southern Theater Command from January 2019 to November 2020 were included in the study, and they were randomly divided into control group ( n=54) and observation group ( n=54). The control group used the cluster training mode for CPR teaching, and the observation group used CDIO combined with the cluster training mode for CPR teaching. The theoretical performance, operation performance, comprehensive ability, chest compression quality and CPR time of the two groups of interns were compared, and the scores of post competency and satisfaction of the two groups of interns were evaluated. SPSS 22.0 was used for t test and chi-square test. Results:The scores of theory, operation and comprehensive ability in the observation group were higher than those in the control group. Compared with those before training, the compression depth, compression frequency and chest rebound rate of the observation group were higher than those of the control group. The observation group found that the patients' unconscious judgment of pulse free time, the time from the occurrence of ventricular fibrillation to the start of automated external defibrillator (AED), and the time to complete AED were lower than those in the control group. The five dimensions of practical ability, critical thinking ability, coordination ability, career development ability, psychological characteristics and the total score of post competency in the observation group were higher than those in the control group ( P < 0.05). The satisfaction of the observation group with the teaching teacher, practice content, practice form and practice effect was higher than that of the control group ( P<0.05). Conclusion:The application of CDIO combined with cluster training in clinical CPR teaching can improve the interns' theoretical performance, operational performance and comprehensive ability, improve the quality of external chest compression and CPR time, make the interns have good communication ability and post competency, and finally improve the interns' satisfaction.
摘要
Digestive system cancers, including liver, gastric, colon, esophageal and pancreatic cancers, are the leading cause of cancers with high morbidity and mortality, and the question of their clinical treatment is still open. Previous studies have indicated that Ziyuglycoside II (ZYG II), the major bioactive ingredient extract from Sanguisorba officinalis L., significantly inhibits the growth of various cancer cells. However, the selective anti-tumor effects of ZYG II against digestive system cancers are not systemically investigated. In this study, we reported the anti-cancer effect of ZYG II on esophageal cancer cells (OE21), cholangiocarcinoma cells (HuCCT1), gastric cancer cells (BGC-823), liver cancer cells (HepG2), human colonic cancer cells (HCT116), and pancreatic cancer cells (PANC-1). We also found that ZYG II induced cell cycle arrest, oxidative stress and mitochondrial apoptosis. Network pharmacology analysis suggested that UBC, EGFR and IKBKG are predicted targets of ZYG II. EGFR signaling was suggested as the critical pathway underlying the anti-cancer effects of ZYG II and both docking simulation and western blot analysis demonstrated that ZYG II was a potential EGFR inhibitor. Furthermore, our results showed synergistic inhibitory effects of ZYG II and chemotherapy 5-FU on the growth of cancer cells. In summary, ZYG II are effective anti-tumor agents against digestive cancers. Further systemic evaluation of the anti-cancer activities in vitro and in vivo and characterization of underlying mechanism will promote the development of novel supplementary therapeutic strategies based on ZYG II for the treatment of digestive system cancers.

OBJECTIVE@#To explore the correlation between the genotypes and metabolic markers and microstructure of bones in children with Gitelman syndrome (GS).@*METHODS@#For 15 children with GS and 10 healthy individuals, baseline data and bone metabolic markers including parathyroid hormone, alkaline phosphatase, osteocalcin, N-terminal propeptide of type I procollagen, beta isomer of the C-terminal telopeptide of type I collagen and 25-hydroxyvitamin D, high-resolution peripheral quantitative computed tomography indicators (volumetric bone mineral density, bone microstructure indicators) were collected. Genetic testing was carried out to determine their genotypes.@*RESULTS@#The volumetric bone mineral density, bone geometry and bone microstructure parameters of the GS group were better than those of the healthy controls (P<0.05). Variants of the SLC12A3 gene were identified in 9 of the 15 patients but none of the 10 healthy controls.@*CONCLUSION@#The phenotype of GS children is influenced by the interaction of genetic variants, though the phenotype associated with high frequency mutations showed no specificity. There is also a correlation between their genotype and the bone microstructure.

Objective:Objective To explore the special role of nutrition specialists in the one-day-care clinic of gestational diabetes mellitus (GDM), and provide a basis for strengthening the standardized construction of one-day-care clinic.Methods:It was a retrospective observation study that the pregnant women who participated in the one-day-care clinic of GDM in our hospital without nutrition specialists in November and December 2017 were divided into control group (177 cases), and who participated in the one-day-care clinic of GDM in our hospital with nutrition specialists in January and February 2018 were divided into observation group (307 cases). The differences of pregnancy outcomes between the two groups were compared after the propensity score matching.Results:176 pairs of patients were successfully matched with a 1:1 propensity score. The incidence of macrosomia in pregnant women with GDM in the observation group (2.8%) was significantly lower than that in the control group (8.5%) ( P=0.036). There were no significant differences in the weight gain during pregnancy, the gestational week of delivery and the incidences of insulin use, hypertension during pregnancy, preeclampsia, cesarean section, premature infants, premature rupture of membranes, umbilical cord around the neck, and fetal distress between the two groups ( P>0.05). Conclusion:Nutrition specialists are indispensable in the multidisciplinary cooperation of one-day-care clinic of GDM, and they play a key role in considerably lowering the prevalence of macrosomia in GDM pregnant women.

Aim To explore the anti-inflammatory effect of taurolithocholic acid (TLCA) through network pharmacology-based analyses, to verify with in vitro macrophage study and to reveal the possible mechanisms. Methods The potential targets of TLCA were acquired from public database, and then the protein-protein interaction (PPI) networks against inflammation were constructed and visualized by using Cytoscape. Gene ontology (GO) analyses and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were performed. The binding activity of TLCA and its target (TGR5) was evaluated through molecular docking analysis. Lastly, the results of the network analysis were confirmed by lipopolysaccharide and interferon-γ induced RAW264.7 cells. Results There were 87 anti-inflammatory potential targets were screened. GO analysis revealed gene functions were mainly involved in regulation of inflammatory response, membrane raft and protein tyrosine kinase. The results of KEGG pathway analysis suggested that PI3K-Akt signaling pathway, human cytomegalovirus infection might be the critical pathways of TLCA against inflammation. The results of in vitro experiments showed that TLCA decreased the LPS and IFN-γ induced inflammatory response in RAW 264.7 macrophages. Furthermore, the expression of TGR5 protein increased after TLCA treatment. Conclusions The potential therapeutic targets of TLCA against inflammation are revealed through network pharmacology analysis. Our results indicate that TLCA might regulate key inflammatory markers through the membrane receptor TGR5.
