Objective To investigate the mechanism by which lectin-like oxidized low density lipoprotein receptor-1(LOX-1)regulates hyperglycemic-induced myocardial fibroblast(CFs)fibrosis through the glycogen synthase kinase-3β(GSK-3β)/signal transducer and activator of transcription 3(STAT3)pathway.Methods CFs were isolated,cultured and identified.LOX-1 RNAi lentiviral vector was constructed and infected CFs.The experimental groups were as follows:Normal control(NC)group,High glucose(HG)group,LV-LOX-1,LV-Con group,Hypertonic(HPG)group.After LV-LOX-1 and LV-Con were infected with CFs,adding 25 mmol/L glucose to culture CFs for 24 h,they were denoted as HG+LV-LOX-1 group and HG+LV-Con group.Cells in HG+LV-LOX-1 group and HG+LV-Con group were treated with 10 μ mol/L SB216763 and 10 μ mol/L STATTIC for 24 h,respectively,and then they were recorded as HG+LV-LOX-1+SB216763 group,HG+LV-Con+SB216763 group,HG+LV-LOX-1+STATTIC group and HG+LV-Con+STATTIC group.CCK-8 was used to detect the activity of CFs,and the expression levels of mRAN and protein of LOX-1,collagen type I(COL-I),thioredoxin 5(TXNDC5),GSK-3β,STAT3,p-GSK-3β and p-STAT3 were detected by qRT-PCR and Western blot.Results CFs infected with LOX-1 RNAi lentiviral vector were obtained,which showed green under fluorescence microscopy.Compared with HG and HG+LV-Con groups,the mRNA expressions of LOX-1,COL-I and TXNDC5 were decreased in HG+LV-LOX-1 group(P<0.05).Compared with HG+LV-LOX-1 group,mRNA expressions of COL-I and TXNDC5 were decreased in HG+LV-LOX-1+SB216763 and HG+LV-LOX-1+STATTIC groups(P<0.05).Compared with HG and HG+LV-Con groups,p-GSK-3β protein expression was increased in HG+LV-LOX-1 group(P<0.05),while LOX-1,p-STAT3,COL-I,TXNDC5 protein expression was decreased in HG+LV-LOX-1 group(P<0.05).Compared with HG+LV-LOX-1 group,p-GSK-3β protein expression was increased in HG+LV-LOX-1+SB216763 group(P<0.05),while the protein expressions of p-STAT3,COL-I and TXNDC5 were decreased in HG+LV-LOX-1+SB216763 and HG+LV-LOX-1+STATTIC groups(P<0.05).Conclusion LOX-1,GSK-3β,STAT3,TXNDC5,and COL-I are involved in high glucose induced CFs fibrosis.LOX-1 promotes the expression of TXNDC5 and COL-I through GSK-3β/STAT3 pathway,and inhibition of LOX-1 can inhibit high glucose induced CFs fibrosis.

Objective To investigate the molecular mechanism of lectin-like oxidized low-density lipoprotein receptor 1(LOX-1)in the regulation of high glucose induced phagocytosis dysfunction of mouse microglia(BV2 microglia).Methods BV2 cells were cultured in vitro,lentivirus LOX-1RNAi vector(LV-LOX-1)and lentivirusempty vector(LV-Con)were constructed and divided into normal control(NC)group,HG group,LV-LOX-1 group and LV-Con group.After infecting BV2 cells with LV-LOX-1 and LV-Con,the cells were cultured with 25 mmol/L glucose for 24 h,and then divided into HG+LV-LOX-1 group and HG+LV-Con group.After treatment of HG+LV-LOX-1 and HG+LV-Con infected BV2 microglia with 15 μmol/L FH535(β-catenin inhibitor)and AEBSF(ATF6α inhibitor)for 24 h,respectively,they were denoted as HG+LV-LOX-1+FH535 group,HG+LV-Con+FH535 group,HG+LV-LOX-1+AEBSF group,and HG+LV-Con+AEBSF group.Transfection efficiency was determined by fluorescence microscopy,RT-PCR and Western blot.Cell viability was detected b CCK-8.RT-PCR and Western blot were used to detect the mRNA and protein expression of LOX-1,β-catenin,ATF6α and milk fat globular-surface growth factor Ⅷ(MFG-E8)in each group.Results After 72 h of LV-LOX-1 infection,the cells in LV-LOX-1 and LV-Con groups showed a lot of green fluorescence,but not in NC group.Compared with NC group,the mRNA and protein expression of LOX-1 and ATF6α were increased(P<0.05),while the mRNA and protein expression of MFG-E8 and β-catenin decreased in HG group(P<0.05).Compared with HG+LV-Con group,the mRNA and protein expression of LOX-1 and ATF6α were decreased(P<0.05),while the mRNA and protein expression of MFG-E8 and β-catenin increasedin HG+LV-LOX-1 group(P<0.05).Compared with HG+LV-LOX-1 group,the mRNA and protein expressions of MFG-E8 and β-catenin were decreased(P<0.05),and the mRNA and protein expressions of ATF6α and p-β-catenin and p-ATF6α were increased in HG+LV-LOX-1+FH535 group(P<0.05).Compared with HG+LV-LOX-1 group,the mRNA and protein expression were increased(P<0.05),ATF6α mRNA and protein expression and p-ATF6α protein expression were decreased MFG-E8 in HG+LV-LOX-1+AEBSF group(P<0.05).Conclusions LOX-1,MFG-E8,β-catenin and ATF6α are involved in the regulation of phagocytosis of BV2 cells.LOX-1 promotes the phagocytosis dysfunction of BV2 microglia induced by high glucose through β-catenin/ATF6α signaling pathway.

Magneto-acoustic-electric tomography (MAET) boasts high resolution in ultrasound imaging and high contrast in electrical impedance imaging, making it of significant research value in the fields of early tumor diagnosis and bioelectrical monitoring. In this study, a method was proposed that combined high conductivity liquid metal and maximum length sequence (M sequence) coded excitation to improve the signal-to-noise ratio. It was shown that, under rotational scanning, the liquid metal significantly improved the signal-to-noise ratio of the inter-tissue magneto-acoustic-electric signal and enhanced the quality of the reconstructed image. The signal-to-noise ratio of the signal was increased by 5.6, 11.1, 21.7, and 45.7 times under the excitation of 7-, 15-, 31-, and 63-bit M sequence code, respectively. The total usage time of 31-bit M sequence coded excitation imaging was shortened by 75.6% compared with single-pulse excitation when the same signal-to-noise ratio was improved. In conclusion, the imaging method combining liquid metal and M-sequence coding excitation has positive significance for improving MAET image quality.

Patients who initiated peritoneal dialysis (PD) in Sichuan Provincial People's Hospital from January 1, 2001 to December 31, 2013 were enrolled in the single center and retrospective study. Clinical and laboratory data were collected to analyze the long-term survival rates, technique survival rates and associated influencing factors. Patients were followed up until December 31, 2021 or endpoints occurred (death or stopping PD treatment). Kaplan-Meier survival curves were used to estimate survival rates and technique survival rates. Cox proportional hazards regression model was used to analyze the risk factors of death and technique failure in PD patients. A total of 373 patients were enrolled in the study, with age of (52.1±15.8) years old and 199 (53.4%) males. During the follow-up, 154 (41.3%) patients died, 72 (19.3%) patients transferred to hemodialysis, and 40 (10.7%) patients received kidney transplant. Kaplan-Meier survival curves revealed that overall survival rates of PD patients at 1, 3, 5, 7, and 10 years were 92.2%, 76.6%, 66.0%, 52.4% and 38.6%, respectively. Technique survival rates were 93.5%, 84.8%, 74.2%, 62.8% and 44.5% at 1, 3, 5, 7, and 10 years, respectively. Multivariate Cox regression model results showed that age ( HR=1.055, 95% CI 1.039-1.073, P<0.001), transfer from hemodialysis ( HR=2.212, 95% CI 1.514-3.231, P<0.001), episodes of peritonitis ( HR=2.141, 95% CI 1.194-3.837, P=0.011), Charlson comorbidity index ( HR=1.525, 95% CI 1.305-1.783, P<0.001), and baseline albumin ( HR=0.951, 95% CI 0.925-0.978, P<0.001) were independent influencing factors of survival in PD patients. Episodes of peritonitis ( HR=2.327, 95% CI 1.274-4.250, P=0.006) and Charlson comorbidity index ( HR=1.244, 95% CI 1.035-1.496, P=0.020) were independent influencing factors of technique survival in PD patients. PD patients have good early survival rates and technical survival rates, but long-term outcomes need to be further improved. Peritonitis is a major risk factor for low long-term survival rates and technical survival rates in PD patients.

Transcranial magnetic stimulation (TMS) combined with electroencephalography (EEG) is a non-invasive technique for studying the excitability and connectivity of the brain cortex, which has been applied in basic scientific research and clinical disease assessment. However, the applicability of TMS-EEG is limited due to artifacts of both biological and abiotic nature induced by TMS pulse output. To address this issue, in the past decade, researchers have developed various TMS-EEG artifact removal methods from two perspectives, including online experimental design and offline data post-processing, and have achieved numerous valuable results. In this paper, the currently available TMS-EEG artifact removal methods are reviewed to facilitate the application of TMS-EEG in basic research and clinical disease diagnosis and treatment.

Objective:To observe the efficacy and safety of recombinant human thrombopoietin (rhTPO) in the treatment of radiation induced thrombocytopenia (RIT) .Methods:From January 2019 to March 2021, 204 cases (including 101 cases of radiotherapy alone and 103 cases of concurrent chemoradiotherapy) were collected retrospectively after radiotherapy and with decreased in blood platelet count <75×10 9/L in Jilin Cancer Hospital. These patients received rhTPO 15 000 U, once a day, subcutaneous, for at least 4 consecutive days, or met the withdrawal criteria blood platelet count ≥100×10 9/L, or the absolute value of blood platelet increase ≥50×10 9/L. The characteristics of blood platelet decline, treatment efficacy, and safety were analyzed. Results:The numbers of radiotherapy treatments with platelets lower than 75×10 9/L in the radiotherapy alone group and the concurrent chemoradiotherapy group were 19 (13, 22) and 13 (10, 17) times, respectively, indicating that patients in the concurrent chemoradiotherapy group experienced platelet decline earlier ( Z=-5.27, P<0.001), the lowest values of platelet decline in the two groups were 68 (45, 74) ×10 9/L and 62 (44, 74) ×10 9/L, respectively, with no statistically significant difference ( Z=-1.15, P=0.252). After received rhTPO treatment, the numbers of days that the two groups of patients had platelets <50×10 9/L were 7 (3, 13) d and 7 (5, 11) d, respectively, with no statistically significant difference ( Z=-1.13, P=0.281). After the patients received radiotherapy, rhTPO was started when the platelet count dropped to <75×10 9/L. The number of days required to recover to 75×10 9/L was 4 (2, 10) d in the radiotherapy alone group and 4 (2, 8) d in the concurrent chemoradiotherapy group, with no statistically significant difference ( Z=-1.07, P=0.285) ; the number of days required for platelets to recover to 100×10 9/L or for the absolute value to increase by 50×10 9/L was 8 (6, 14) d in the radiotherapy alone group and 11 (8, 16) d in the concurrent chemoradiotherapy group. The recovery time of the concurrent chemoradiotherapy group was longer than that of the radiotherapy alone group ( Z=-3.64, P<0.001). Regardless of the baseline level, there was no statistically significant difference in the number of days for platelets to recover to 75×10 9/L after rhTPO treatment between the radiotherapy alone group and the concurrent chemoradiotherapy group ( Z=-1.42, P=0.155; Z=-0.97, P=0.332). The number of days required for the two groups of patients to recover to 100×10 9/L or for the absolute value to increase by 50×10 9/L were 8 (6, 14) d and 11 (8, 16) d, respectively, with a statistically significant difference ( Z=-3.64, P<0.001). The numbers of days required for the two groups of patients with baseline platelets ≥50×10 9/L to recover to 100×10 9/L or for the absolute value to increase by 50×10 9/L were 8 (4, 12) d and 10 (8, 16) d, respectively, with a statistically significant difference ( Z=-3.12, P=0.002). However, there was no statistically significant difference in the number of days required for the two groups of patients with baseline platelets <50×10 9/L to recover to 100×10 9/L or for the absolute value to increase by 50×10 9/L ( Z=-1.88, P=0.061). The total platelet elevation rate of rhTPO within 20 days of radiotherapy treatment for both groups of patients was 93.63% (191/204), of which 95.05% (96/101) was for radiotherapy alone and 92.23% (95/103) for concurrent chemoradiotherapy, with no statistically significant difference ( χ2=0.68, P=0.410). In addition, there was no statistically significant difference in gender ( χ2=3.47, P=0.063), age ( χ2=2.79, P=0.095), TNM staging ( χ2=5.07, P=0.167), and baseline platelet count ( χ2=0.62, P=0.822) between the two groups.During the radiotherapy cycle, 27 patients (13.23%) received blood platelet infusion, and 158 patients (77.45%) completed the radiotherapy plan without interruption. No rhTPO-related adverse reactions were found. Conclusion:rhTPO in the treatment for RIT can effectively promote the recovery of blood platelet without any adverse reactions, and has good safety.

Objective:To investigate the effect of follicular phase long-acting gonadotropin-releasing hormone (GnRH) agonist long protocol on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes of patients with endometriosis (EMS). Methods:This retrospective cohort study was carried out from July 1st 2015 to June 30th 2019 and enrolled 383 young patients with EMS who underwent the first IVF/ICSI. According to the controlled ovarian hyperstimulation protocols, patients were classified into three groups: follicular phase long-acting GnRH agonist long protocol group (group A), short-acting GnRH agonist long protocol group (group B) and GnRH antagonist protocol group (group C). The clinical outcomes of IVF/ICSI were compared among the groups by using univariate and multivariate logistic regression analyses.Results:The patients with EMS in group A had significantly higher duration of stimulation and total dosage of gonadotrophin (Gn) used [11 (9,13) d, 2700 (2250, 3200) IU] than those in group B and group C [9 (8,10) d, 1875 (1575, 2250) IU; 8 (8,9) d, 1800 (1425, 2250) IU] (all P<0.001). Serum levels of luteinizing hormone (LH) [0.64 (0.35, 0.99) IU/L vs. 1.78 (1.42, 2.05) IU/L vs. 5.00 (3.63, 6.46) IU/L; 0.89 (0.37, 1.33) IU/L vs. 2.48 (1.76, 3.25) IU/L vs. 2.46 (1.66, 3.67) IU/L] and estradiol [6.70 (5.00,16.90) μg/L vs. 7.93 (6.50, 7.93) μg/L vs. 34.05 (22.99, 45.58) μg/L; 1.82 (1.11, 2.75) μg/L vs. 2.97 (2.16,4.24) μg/L vs. 2.03 (1.49, 2.96) μg/L) on Gn initiation day and human chorionic gonadotropin (hCG) injection day were significantly lower in group A (all P<0.001). Group A had significantly higher clinical pregnancy rate [76.53% (75/98)], implantation rate [54.10% (99/183)] and live birth rate [66.33% (65/98)] compared with those in group B and group C [61.39% (62/101) and 54.39% (31/57), P=0.010; 42.63% (81/190), and 40.19% (43/107), P=0.029; 53.47% (54/101), and 47.37% (27/57), P=0.046]. Conclusion:Follicular phase long-acting GnRH agonist protocol could improve IVF/ICSI outcomes of patients with EMS compared with short-acting GnRH agonist long protocol and GnRH antagonist protocol.
