ABSTRACT

Objective:To explore the myocardial protective effect of nicorandil preoperative intervention on patients with heart disease undergoing hip replacement surgery.Methods:The case data of 117 patients undergoing hip arthroplasty in Rugao Branch Affiliated Hospital of Nantong University from June 2018 to December 2020 were retrospectively analyzed. According to whether nicorandil was given before surgery, they were divided into two groups. The group A and group B was given routine preoperative general anesthesia, and the group B was given nicorandil before surgery. The surgery-related indicators, inflammatory factors, myocardial damage, major adverse cardiac events (MACE) werecompared between the two groups.Results:The operation time, intraoperative blood loss, intraoperative fluid rehydration, urine output, Ramsay sedation score on the first day after surgery, visual analogue scale (VAS) score on the first day after surgery, and hospital stay in the two groups had no significant differences ( P>0.05). The levels of serum interleukin-6, tumor necrosis factor -α, C-reactive protein, cardiac troponin I, creatine kinase-MB, myoglobin andipoprotein associated phospholipase A2 postoperative in group B were lower than those in the group A: (388.15 ± 56.20) μg/L vs. (456.34 ± 65.18) μg/L, (34.24 ± 8.90) μg/L vs. (40.26 ± 10.22) μg/L, (27.54 ± 5.52) mg/L vs. (30.25 ± 5.61) mg/L, (0.10 ± 0.05) μg/L vs. (0.19 ± 0.08) μg/L, 0.059 ± 0.019 vs. 0.099 ± 0.026, (68.41 ± 6.03) μg/L vs. (76.61 ± 6.54) μg/L, (201.67 ± 25.88) μg/L vs. (251.37 ± 31.06) μg/L, the differences were statistically significant ( P<0.05). There was no statistically significant difference in the total incidence of MACE between the two groups ( P>0.05). Conclusions:Nicorandil intervention before hip replacement surgery can effectively improve the levels of inflammatory factors in patients with heart disease and reduce the degree of myocardial damage.Whether it can reduce the risk of MACE after surgery still needs to be further demonstrated.

ABSTRACT

OBJECTIVES@#To investigate the clinical characteristics and risk factors for early-onset necrotizing enterocolitis (NEC) in preterm infants with very/extremely low birth weight (VLBW/ELBW).@*METHODS@#A retrospective analysis was performed on the medical data of 194 VLBW/ELBW preterm infants with NEC who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2014 to December 2021. These infants were divided into early-onset group (onset in the first two weeks of life; n=62) and late-onset group (onset two weeks after birth; n=132) based on their onset time. The two groups were compared in terms of perinatal conditions, clinical characteristics, laboratory examination results, and clinical outcomes. Sixty-two non-NEC infants with similar gestational age and birth weight who were hospitalized at the same period as these NEC preterm infants were selected as the control group. The risk factors for the development of early-onset NEC were identified using multivariate logistic regression analysis.@*RESULTS@#Compared with the late-onset group, the early-onset group had significantly higher proportions of infants with 1-minute Apgar score ≤3, stage III NEC, surgical intervention, grade ≥3 intraventricular hemorrhage, apnea, and fever or hypothermia (P<0.05). The multivariate logistic regression analysis showed that feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, and hemodynamically significant patent ductus arteriosus were independent risk factors for the development of early-onset NEC in VLBW/ELBW preterm infants (P<0.05).@*CONCLUSIONS@#VLBW/ELBW preterm infants with early-onset NEC have more severe conditions compared with those with late-onset NEC. Neonates with feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, or hemodynamically significant patent ductus arteriosus have a higher risk of early-onset NEC.

ABSTRACT

OBJECTIVE@#To observe the effect of fire needling on prostate symptoms, quality of life, average daily number of nightly urination, urine flow rate and prostat volume in patients with mild to moderate benign prostatic hyperplasia (BPH) of kidney yang deficiency.@*METHODS@#A total of 60 patients with mild to moderate BPH of kidney yang deficiency were randomly divided into an observation group (30 cases, 3 cases dropped off) and a control group (30 cases, 4 cases dropped off). The observation group was treated with fire needling at Guanyuan (CV 4), Shuidao (ST 28) and Qugu (CV 2) twice a week (2-3 d interval between each treatment), continuous treatment for 4 weeks. The control group received lifestyle advice and education, once a week for 4 weeks. In the two groups, the international prostate symptom score (IPSS), the quality of life (QoL) score and the average daily number of nightly urination were observed before treatment, after treatment and during the follow-up of the 4th week; the urinary maximum flow rate (Qmax), the average flow rate (Qave), and the prostate volume were assessed before and after treatment in the two groups. The safety was observed in the observation group.@*RESULTS@#After treatment and during follow-up, the IPSS scores, QoL scores, and the average daily number of nightly urination in the observation group were decreased compared with those before treatment (P<0.05), and those in the observation group were lower than the control group (P<0.05). After treatment, there was no significant difference in Qmax, Qave and prostate volume between the two groups and within the each group (P>0.05). There were no fire needling-related adverse reactions, and no obvious abnormality was found in urine routine and coagulation function tests before and after treatment in the observation group.@*CONCLUSION@#Fire needling can improve lower urinary tract symptoms and quality of life, reduce frequency of nightly urination in patients with mild to moderate BPH of kidney yang deficiency, and has good safety.

ABSTRACT

Tu-Xian decoction (TXD), a traditional Chinese medicine (TCM) formula, has been frequently administered to manage diabetic cognitive impairment (DCI). Despite its widespread use, the mechanisms underlying TXD's protective effects on DCI have yet to be fully elucidated. As a significant regulator in neurodegenerative conditions, death-associated protein kinase-1 (DAPK-1) serves as a focus for understanding the action of TXD. This study was designed to whether TXD mediates its beneficial outcomes by inhibiting DAPK-1. To this end, a diabetic model was established using Sprague-Dawley (SD) rats through a high-fat, high-sugar (HFHS) diet regimen, followed by streptozotocin (STZ) injection. The experimental cohort was stratified into six groups: Control, Diabetic, TC-DAPK6, high-dose TXD, medium-dose TXD, and low-dose TXD groups. Following a 12-week treatment period, various assessments-including blood glucose levels, body weight measurements, Morris water maze (MWM) testing for cognitive function, brain magnetic resonance imaging (MRI), and histological analyses using hematoxylin-eosin (H&E), and Nissl staining-were conducted. Protein expression in the hippocampus was quantified through Western blotting analysis. The results revealed that TXD significantly improved spatial learning and memory abilities, and preserved hippocampal structure in diabetic rats. Importantly, TXD administration led to a down-regulation of proteins indicative of neurological damage and suppressed DAPK-1 activity within the hippocampal region. These results underscore TXD's potential in mitigating DCIvia DAPK-1 inhibition, positioning it as a viable therapeutic candidate for addressing this condition. Further investigation into TXD's molecular mechanisms may elucidate new pathways for the treatment of DCI.

ABSTRACT

There are many types in food allergy, and the most common is mediated by IgE. Currently, the diagnosis of food allergy mainly relied on skin prick test and serum specific IgE of allergen extract, which can not identify cross-sensitization. Component-resolved diagnosis (CRD) can identify the major allergen components and cross-components of food allergens, which plays an important role in dietary guidance, prognosis monitoring and diagnosis of special types of IgE-mediated food allergy. This article enumerates clinical characteristics of the IgE-mediated common food allergies, such as milk, egg and seafood allergy, and special type of food allergy, such as cat pork syndrome, oral allergy syndrome, α-gal syndrome and food-dependent exercise-induced anaphylaxis, summarizes the advances of CRD in these types of IgE-mediated food allergy, in order to provide an evidence for the diagnosis, treatment and prevention of IgE-mediated food allergy.

ABSTRACT

Keratoconus is a chronic, non-inflammatory corneal disease, characterized by thinning of the corneal stroma and local corneal dilation with cone-shaped protrusion, and it usually leads to irregular astigmatism and myopia, posing great threat to eyesight. Corneal topography is the primary diagnostic tool for confirming keratoconus, while optical coherence tomography is now playing an increasingly important role in the diagnosis and treatment of keratoconus due to its ability of corneal sublayer imaging and superiority in repeatability, resolution, and data acquisition speed. This article discusses and reviews the clinical characteristics of keratoconus, the classification and characteristics of optical coherence tomography and its novel applications in the early diagnosis of keratoconus, contact lens fitting, corneal cross-linking therapy, and corneal transplantation; furthermore, progress in derivative technologies including optical coherence elastography, optical coherence tomography angiography, and polarization-sensitive optical coherence tomography associated with keratoconus is included in this article. We hope our study will help to further exploit the role of optical coherence technology in clinical keratoconus management.

ABSTRACT

ObjectiveTo develop a bilateral rehabilitation robot motion assistance strategy based on admittance control, so that rehabilitation physicians can assist patients in rehabilitation training through remote teaching. MethodsA bilateral remote rehabilitation platform with upper limb terminal traction was constructed. Based on the velocity admittance control, the interactive movement between the master robot and the rehabilitation physician was realized, and the position information transmission of the master-slave robot was realized through the communication framework built. The slave robot received the position coordinates of the main robot, and drove the patient to carry out rehabilitation exercises under the attitude admittance controller. ResultsThe robot could drive the patient to accurately track the trajectory of the doctor's teaching in real time, and improve the safety and compliance of the training and human-computer interaction. ConclusionBy introducing two admittance controllers, the trajectory of the physician's end can be accurately tracked when driving the patient's movement from the robotic arm, which effectively avoids the discomfort of the patient's arm in process of rehabilitation.

ABSTRACT

Starting from the perspective of meridian theory, this article briefly analyzes the meridian pathophysiology of snoring and the relationship between snoring and meridian theory. It proposes that acupuncture treatment for snoring should focus on regulating qi from the shaoyang meridians, harmonizing the spirit by the governor vessel, resolving phlegm through the three yang meridians, and harmonizing qi and blood from the yangming meridians. Additionally, attention is placed on both the root cause and the symptoms, the theory of "four seas". The ultimate goal is to promote the flow of meridian and qi-blood, improve symptoms such as nighttime snoring, poor sleep quality, and daytime sleepiness, and achieve the desired outcome of stopping snoring and ensuring restful sleep.

ABSTRACT

OBJECTIVE@#To investigate the mechanism of drug reversing resistance of Agaricus blazei extract FA-2-b-β on T cell acute lymphoblastic leukemia (T-ALL) cell lines.@*METHODS@#Cell proliferation was detected by CCK-8 assay; the apoptosis, cell cycle mitochondrial membrane potential, and intracellular rhodamine accumulation were detected by flow cytometry, and apoptosis-related gene and protein expression were detected by qPCR and Western blot; the membrane surface protein MDR1 was observed by immunofluorescence microscopy.@*RESULTS@#Different concentrations of FA-2-b-β significantly inhibited proliferation and induced apoptosis of CCRF-CEM and CEM/C1 (P<0.05), and CCRF-CEM cell cycle were arrested at S phase, and CEM/C1 cells were arrested at G0/G1 phase. Western blot and qPCR results show that FA-2-b-β inhibited ABCB1、ABCG2、CTNNB、MYC and BCL-2 expression, but upregulated Bax expression. In addition, FA-2-b-β reversed the resistance characteristics of CEM/C1 drug-resistance cells, which decreased mitochondrial membrane potential, and significantly increased the intracellular rhodamine accumulation, and weakening of the expression of the membrane surface protein MDR1. With the Wnt/β-catenin inhibitor (ICG001), the process was further intensified.@*CONCLUSION@#Agaricus Blazei Extract FA-2-b-β inhibits cell proliferation, promotes apoptosis, regulates the cell cycle, reduces mitochondrial energy supply, and down-regulate MDR1 expression to reverse the resistance of CEM/C1, which all suggest it is through regulating the Wnt signaling pathway in T-ALL.

ABSTRACT

Objective: To investigate the effects of duration, temperature and shake on paraquat (PQ) concentration in the blood of PQ-exposed rats during the specinen preservation and transportation. Methods: In March 2021, 60 SD male rats of Specific Pathogen Free class were randomly divided into low-dose group (10 mg/kg PQ) and high-dose group (80 mg/kg PQ). Each group was divided into 5 subgroups (normal temperature group, cold storage group, 37 ℃ storage group, shaking on normal temperature group and shaking on 37 ℃ group), six rats in each subgroup. The rats were given intraperitoneal injection of PQ, 1 h after exposure, the blood samples were obtained by cardiac extraction. After different interventions, the concentrations of PQ were detected and compared before and after the intervention in each subgroup. Results: In the shaking on 37 ℃ group, the results of PQ concentrations in PQ-exposed rats were significantly lower than those before the intervention (P<0.05). In the other subgroups, the results were not significantly different compared with before intervention (P>0.05) . Conclusion: The concentration of PQ in the blood of rats exposed to PQ was decreased by shaking for 4 hours at 37 ℃.

ABSTRACT

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.

ABSTRACT

OBJECTIVE@#To determine whether salvianolic acid B (Sal B) exerts protective effects on diabetic peripheral neuropathy by attenuating apoptosis and pyroptosis.@*METHODS@#RSC96 cells were primarily cultured with DMEM (5.6 mmol/L glucose), hyperglycemia (HG, 125 mmol/L glucose) and Sal B (0.1, 1, and 10 µ mol/L). Cells proliferation was measured by 3-(4, 5-cimethylthiazol-2-yl)-2, 5-dilphenyltetrazolium bromide assay. Reactive oxygen species (ROS) generation and apoptosis rate were detected by flow cytometry analysis. Western blot was performed to analyze the expressions of poly ADP-ribose polymerase (PARP), cleaved-caspase 3, cleaved-caspase 9, Bcl-2, Bax, NLRP3, ASC, and interleukin (IL)-1β.@*RESULTS@#Treatment with HG at a concentration of 125 mmol/L attenuated cellular proliferation, while Sal B alleviated this injury (P<0.05). In addition, Sal B inhibited HG-induced ROS production and apoptosis rate (P<0.05). Furthermore, treatment with Sal B down-regulated HG-induced PARP, cleaved-caspase 3, cleaved-caspase 9, Bax, NLRP3, ASC, and IL-1β expression, but mitigated HG-mediated down-regulation of Bcl-2 expression (P<0.05).@*CONCLUSION@#Sal B may protect RSC96 cells against HG-induced cellular injury via the inhibition of apoptosis and pyroptosis activated by ROS.

ABSTRACT

Aim To investigate the role of collybistin in the regulation of pain transmission. Methods The distribution of collybistin in spinal cord was observed by immunohistochemical staining. The role of collybis¬tin in pain transmission was evaluated by behavioral experiments. The effect of collybistin on inhibitory synap¬tic transmission was studied by electrophysiological ex¬periments. Results Collybistin was distributed in spi¬nal cord neurons; ShRNA-collybistin induced pain sen-sitization of intact mice ( P < 0. 05 ) . Overexpression of collybistin in spinal cord significantly alleviated pain sensitization induced by peripheral nerve injury ( P <0. 05 ) . ShRNA-collybistin also significantly reduced the amplitudes and frequencies of miniature inhibitory postsynaptic currents (mlPSCs) in superficial neurons of spinal cord dorsal horn (P <0. 05) . Overexpression of collybistin in spinal cord could reverse the effects of peripheral nerve injury on mlPSCs (P <0. 05). Con¬clusions Collybistin is involved in pain sensitization induced by peripheral nerve injury in mice.

ABSTRACT

Objective: To assess low-density lipoprotein cholesterol (LDL-C) levels and use of lipid-lowering treatment among young and middle-aged ultra-high-risk patients with acute coronary syndrome (ACS) in China. Methods: The study was based on the"Improving Care for Cardiovascular Disease in China (CCC)-ACS"project, a collaborative registry by and Chinese Society of Cardiology (CSC) and the American Heart Association. Hospitalized-patients with ACS were consecutively enrolled from 159 tertiary and 82 secondary hospitals across China, related clinical information was collected. This study included young and middle-aged hospitalized patients (18-59 years) with ACS from November 2014 to December 2019 registered in CCC-ACS project. Ultra-high-risk was defined according to Chinese expert consensus on lipid management of ultra-high-risk atherosclerotic cardiovascular disease (ASCVD) patients of CSC. The mean LDL-C levels at admission, pre-hospital lipid-lowering therapy and proportion of patients with LDL-C target achieved were analyzed. Results: A total of 42 230 patients younger than 60 years with ACS were included in this study. The mean age was (50.4±6.9) years, and 86.8% (36 676/42 230) of the ACS patients were male. Among them, 86.9% (36 687/42 230) met the criteria of ultra-high-risk. The mean level of LDL-C at admission was (2.8±1.0)mmol/L, only 5.3 % (1 948/36 687) patients achieved the targeted goal of LDL-C<1.4 mmol/L. Among the ultra-high-risk ASCVD patients, 17.5% (6 430/36 687) received lipid-lowering drugs before hospitalization, 96.4% (6 198/6 430) of whom received statins monotherapy. Among patients receiving pre-hospital statins, only 9.9% (626/6 323) patients reached an LDL-C<1.4 mmol/L at admission. Conclusions: The majority of young and middle-aged hospitalized patients with ACS are ultra-high-risk patients for ASCVD in China. Pre-hospital lipid-lowering drugs use is lower in these ultra-high-risk ASCVD patients and most patients do not reach the new LDL-C target level at admission.

ABSTRACT

Objective:To investigate the risk factors associated with failure of trial of labor in primiparous women with preeclampsia (PE) and to establish a risk prediction model.Methods:Primiparae with PE who underwent trial of labor in the Department of Obstetrics of Suzhou Ninth People's Hospital from February 2018 to July 2020 were retrospectively selected as the modeling set, and divided into two groups: the success group and the failure group. Various parameters were compared between the two groups and those data with statistically significant difference were analyzed with multivariate logistic regression analysis. Those factors related to vaginal delivery failure in primiparous women with PE were identified. Based on the results, a risk prediction model was established using R language. Its performance was assessed with receiver operating characteristic (ROC) curve and goodness-of-fit test. This study also retrospectively enrolled primiparae with PE who underwent trial of labor in the same hospital from August 2020 to December 2021 as the validation set. Bootstrap method was used for verification and a calibration chart was created.Results:A total of 312 PE patients were selected as the modeling set with 89 in the failure group and 223 in the success group. Another 146 primiparae with PE were selected as the validation set. Logistic regression analysis showed that older age ( OR=1.609, 95% CI: 1.251-2.483), higher body fat rate in early pregnancy ( OR=1.456, 95% CI: 1.209-2.159) and higher ratio of umbilical artery systolic to diastolic flow velocity within a week before delivery ( OR=1.799, 95% CI: 1.372-2.794) were risk factors for vaginal delivery failure in primiparae with PE, while more maternal education during pregnancy ( OR=0.233, 95% CI: 0.054-0.672) and higher Bishop score ( OR=0.395, 95% CI: 0.258-0.756) were protective factors. A nomogram model to predict the risks of vaginal delivery failure was constructed based on the above five factors. The area under the ROC curve (AUC) of the modeling set was 0.921 (95% CI: 0.847-0.963) with the cut-off value of 0.213, and the corresponding sensitivity and specificity were 0.871 and 0.852, respectively;goodness-of-fit test showed that the observed values matched with those expected ( χ2=7.69, P=0.464); and the calibration curve indicated that the consistency of the prediction model was good. The AUC of the validation set was 0.903 (95% CI: 0.835-0.942) with the sensitivity and specificity of 0.892 and 0.796, respectively; the discrepancy between the observed values and those expected was not significant as indicated by goodness-of-fit test ( χ2=6.82, P=0.512); calibration curve of the validation set showed that the predicted values of the model was consistent with the actual values. Conclusions:The failure of vaginal delivery in primiparae with PE is associated with maternal age, prenatal body fat percentage, ratio of fetal umbilical artery systolic to diastolic flow velocity within a week before delivery, maternal education during pregnancy and Bishop score. The nomogram model based on these five risk factors for prediction of vaginal delivery failure performs well.

ABSTRACT

ObjectiveTo explore the mechanism of antidepressant effect of lily polysaccharide (LLP)and astragalus polysaccharide(APS). MethodSixty KM mice were randomly divided into blank group, model group, fluoxetine hydrochloride (8 mg·kg-1)group, LLP (0.2 g·kg-1)group, APS (0.2 g·kg-1)group and polysaccharide combination (LLP+APS,0.1 g·kg-1+0.1 g·kg-1)group, with 10 mice in each group. Except the blank group, the other groups were given chronic unpredictable mild stress (CUMS) induced mouse depression model. On the 29th day of modeling,fluoxetine hydrochloride group was given corresponding dose of fluoxetine hydrochloride, and polysaccharide groups were given corresponding drug. The depressive behavior of mice was evaluated by behavioral indexes such as body mass change, open field test. The morphological changes of hippocampal CA1 neurons were observed by Nissl staining. The contents of 5-hydroxytryptamine (5-HT), adrenocorticotropic hormone (ACTH), and corticosterone (CORT), in brain tissue and plasma were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the expression levels of related proteins in adenylate cyclase/cyclic adenylate phosphate/protein kinase A (AC/cAMP/PKA) signal pathway. ResultCompared with the blank group, mice in the model group gained weight slowly, the total distance, central distance and sugar water preference rate decreased significantly (P<0.01), the depressive behavior was significant, the hippocampal neurons were seriously damaged, the content of 5-HT decreased (P<0.01), the contents of ACTH and CORT increased significantly (P<0.01), adenylate cyclase 6(ADCY6), PKA and cAMP response element binding protein-1 (CREB-1) and brain-derived neurotrophic factor (BDNF) protein expression decreased significantly (P<0.01). Compared with the model group, depressive behavior of mice in LLP group, APS group and LLP+APS group was significantly improved (P<0.01). The antidepressant effect of LLP+APS was better than that of LLP and APS. Each administration group could alleviate the damage of hippocampal neurons in varying degrees, significantly increase the content of 5-HT in brain tissue (P<0.01), and reduce the levels of ACTH and CORT in plasma (P<0.05). The protein levels of ADCY6, PKA, CREB-1 and BDNF were significantly increased (P<0.05). ConclusionThe antidepressant effect of LLP+APS is significantly enhanced and has a synergistic effect. The mechanism may be closely related to affecting the content of neurotransmitters, inhibiting HPA axis activity and activating AC/cAMP/PKA signal transduction pathway.

ABSTRACT

Objective: Autologous peripheral blood stem cells (PBSC) derived from bone marrow can promote liver regeneration and improve the liver function of patients, but there are few studies on its effect on the long-term outcomes in patients with decompensated cirrhosis. Based on previous work, this study observed the clinical outcomes of PBSC treatment in patients with decompensated cirrhosis for 10 years, in order to provide more data support for the safety and efficacy of stem cells in clinical applications. Methods: Data of patients with decompensated liver cirrhosis who completed PBSC treatment in the Department of Gastroenterology of the First Affiliated Hospital of Air Force Military Medical University from August 2005 to February 2012 were included. The follow-up endpoint was death or liver transplantation, and patients who did not reach the follow-up endpoint were followed-up for at least 10 years. The patients with decompensated liver cirrhosis who met the conditions for PBSC treatment but did not receive PBSC treatment in our hospital during the same period were used as controls. Results: A total of 287 cases with decompensated liver cirrhosis had completed PBSC treatment, and 90 cases were lost to follow-up within 10 years after surgery. A total of 151 cases with complete survival follow-up data were included in the control group. There were no statistically significant differences in baseline information such as gender, age, etiological composition and liver function score between the two groups. The 10-year survival rate was higher in PBSC than control group (37.56% vs. 26.49%, P<0.05). Cholinesterase, albumin, international normalized ratio, Child-Turcotte-Pugh score, model for end-stage liver disease score, and other indicators were gradually recovered within 3 months to 1 year after PBSC treatment, and stabilized at a more desirable level in the long-term after follow-up for up to 10 years. There was no statistically significant difference in the incidence of liver cancer between the two groups (25.22% vs.31.85%, P=0.267). The age of onset of hepatocellular carcinoma was later in PBSC than control group [(56.66±7.21) years vs. (52.69±8.42) years, P<0.05]. Conclusions: This long-term observational follow-up study of more than ten years confirms that PBSC treatment can bring long-term benefits to patients with decompensated cirrhosis, with good long-term safety, thus providing more data support on the safety and efficacy of stem cells for clinical applications.

ABSTRACT

Objective: To explore the expression of miR1290 in endometrial cancer tissues and its relationship with the pathological grade, and to find out the effect of miR1290 on biological characteristics of endometrial cancer cells and its mechanism. Methods: A total of 38 cases of endometrioid adenocarcinoma tissues, 10 cases of adjacent tissues and 23 cases of normal endometrial tissues were collected in Provincial Hospital Affiliated to Shandong University from May 2020 to October 2020. The expression of miR1290 was detected by reverse transcription polymerase chain reaction (RT-PCR). The expressions of miR1290 in endometrial cancer cells including KLE and Ishikawa were knocked down by lentiviral transfection. Cell counting kit 8 (CCK-8) test and colony formation test were used to detect cell proliferation ability, wound healing and Transwell test were used to detect cell invasion and migration ability, western blot was used to detect the expressions of epithelial-mesenchymal transition (EMT), phospholipids acylinositide 3-kinase (PI3K)/Akt and Wnt/β-catenin pathway related proteins. Results: The relative expressions of miR1290 in endometrial cancer tissues were 5.40±3.20, which was 1.55 times of normal endometrial tissues (P<0.01) and 1.75 times of adjacent tissues (P<0.01). The relative expressions of miR1290 in 17 cases of endometrial tissues at proliferative stage and 6 cases of endometrial tissues at secretory stage were 3.00±1.08 and 4.97±0.58, respectively, and the difference was statistically significant (P<0.01). In KLE cells and Ishikawa cells, the expression of miR1290 in miR1290 knockdown (Sh-miR1290) group was decreased when compared with the negative control (Sh-NC) group. The absorbance value of Sh-miR1290 group detected by the CCK-8 method and the colony formation rate detected by the colony formation experiment were both increased, the number of cells penetrating the basement membrane in the Transwell experiment and the wound healing rate in the scratch experiment were decreased (P<0.05). In KLE cells, knockdown of miR1290 reduced the expressions of EMT-related proteins including N-cadherin, Vimentin, Snail and Slug(P<0.05), and the expressions of PI3K and P-Akt/Akt (P<0.05), while there was no significant change in the expressions of Wnt and β-catenin (P>0.05). In Ishikawa cells, knockdown of miR1290 decreased the expressions of EMT-related proteins including N-cadherin, Snail and Slug, and the expressions of Wnt and β-catenin, increased the expression of E-cadherin (P<0.05), while there was no significant change in the expressions of PI3K and P-Akt/Akt (P>0.05). Conclusions: The expressions of miR1290 in endometrial cancer tissues are higher than that in the adjacent tissues and normal endometrial tissues. Knockdown of miR1290 expression can promote the proliferation of endometrial cancer cells, but inhibit cell invasion, migration and EMT ability through the PI3K/Akt and Wnt/β-catenin pathways.
