RESUMEN

Transarterial interventional therapy combined with tyrosine kinase inhibitors (TKIs) and anti-Pd-1 antibodies (triplet regimen) has shown promising results in advanced HCC. However, the clinical utility of the triplet regimen in patients with HCC and major portal vein tumor thrombosis (PVTT) remains unclear. This study compared the efficacy and safety of the triplet regimen versus transarterial interventional therapy combined with TKIs (double regimen) for such patients. Thirty-nine patients treated with the triplet regimen were retrospectively compared with 37 patients treated with the double regimen. The objective response rate (ORR), the response rate of PVTT treatment, and safety were observed; progression-free survival (PFS) and overall survival (OS) were assessed using the Kaplan‒Meier method and log-rank test. Predictors of survival were identified using multivariate analysis. Median OS and median PFS were significantly improved in the Triplet Group compared with the Double Group (482 vs. 310 days; 208 vs. 85 days). The ORR and the response rate of PVTT were significantly higher in the Triplet Group than in the Double Group (59% vs. 35%; 62% vs. 35%). There was no significant difference in the incidence of grade 3/4 adverse events between the two groups (33% vs. 21%). The most frequent grade 3/4 adverse events were thrombocytopenia (10%) in the Triplet Group and hand-foot syndrome (14%) in the Double Group. Multivariable analysis showed that treatment method and PVTT treatment response were significant predictors of OS. The triplet regimen showed superiority over the doublet regimen in improving OS and PFS and had acceptable safety in patients with HCC and major PVTT.

RESUMEN

Thermal injury repair is a complex process during which the maintenance of the proliferation and migration of human skin fibroblasts (HSFs) exert a crucial role. MicroRNAs have been proven to exert an essential function in repairing skin burns. This study delves into the regulatory effects of miR-24-3p on the migration and proliferation of HSFs that have sustained a thermal injury, thereby, providing deeper insight into thermal injury repair pathogenesis. The PPAR-ß protein expression level progressively increased in a time-dependent manner on the 12th, 24th and 48th hour following the thermal injury of the HSFs. The knockdown of PPAR-ß markedly suppressed the proliferation of and migration of HSF. Following thermal injury, the knockdown also promoted the inflammatory cytokine IL-6, TNF-α, PTGS-2 and P65 expression. PPAR-ß contrastingly exhibited an opposite trend. A targeted relationship between PPAR-ß and miR-24-3p was predicted and verified. miR-24-3p inhibited thermal injured HSF proliferation and migration and facilitated inflammatory cytokine expression through the regulation of PPAR-ß. p65 directly targeted the transcriptional precursor of miR-24 and promoted miR-24 expression. A negative correlation between miR-24-3p expression level and PPAR-ß expression level in rats' burnt dermal tissues was observed. Our findings reveal that miR-24-3p is conducive to rehabilitating the denatured dermis, which may be beneficial in providing effective therapy of skin burns.

RESUMEN

BACKGROUND: About 55% of hepatocellular carcinoma (HCC) cases in China are advanced HCC at the initial diagnosis. We aimed to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) for HCC with portal vein tumor thrombosis (PVTT) compared to transcatheter arterial chemoembolization (TACE) after propensity score matching (PSM). METHODS: A propensity score-matched cohort study was performed in patients with advanced HCC with PVTT who underwent either HAIC using oxaliplatin plus raltitrexed or TACE at three institutions between January 2016 and January 2021. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and adverse events were compared between the groups. RESULTS: After PSM, 44 pairs of patients were assessed. The HAIC group had longer OS (11.2 [95% confidence interval [CI]: 9.9-12.5] vs. 9.0 [95% CI: 5.3-12.7] months; p = 0.010), better PFS (5.6 [95% CI: 3.7-7.9] vs. 2.0 [95% CI: 1.3-2.7] months; p = 0.006), and a higher ORR (Response Evaluation Criteria in Solid Tumors [version 1.1]: 56.8% vs. 18.2%; p < 0.001) than the TACE group. In multivariate analysis, HAIC was identified as an independent favorable prognostic factor for survival. CONCLUSIONS: Compared to TACE, HAIC significantly increased the ORR of HCC with portal invasion and prolonged survival without causing a significant increase in severe adverse events.

RESUMEN

BACKGROUND: The impact of smooth endoplasmic reticulum aggregates (SERa) on assisted reproductive technology (ART) outcomes was still controversial. Our objective is to investigate the impact of the presence of SERa on intracytoplasmic sperm injection (ICSI) outcomes. METHODS: This was a retrospective cohort study. A total of 1,090 fresh ICSI cycles from 944 patients between January 2016 and June 2020 were included. Outcomes from clinical, embryological and neonatal aspects were compared between SERa + and SERa- cycles as well as between SERa + and SERa- oocytes. RESULTS: The total gonadotropin (Gn) dose, number of oocytes retrieved, serum estradiol concentration and number of the available embryo were significantly higher in SERa + cycles than in SERa- cycles (P < 0.05). Comparable two pronuclei (2PN) fertilization rate and poly-pronucleus zygote rate were shown in SERa + and SERa- cycles (P > 0.05), but which were higher in SERa + oocytes than in SERa- oocytes (P < 0.05). No statistical difference in blastocyst formation rate was found in SERa + and SERa- cycles as well as in SERa + and SERa- oocytes (P > 0.05). Good-quality embryo rate was statistically higher in SERa- cycles than in SERa + cycles (P < 0.05), but the difference was comparable between SERa + and SERa- oocytes (P > 0.05). No statistical difference in clinical pregnancy rate, spontaneous abortion rate, live birth rate and premature delivery rate were found in SERa + and SERa- cycles as well as in SERa + and SERa- oocytes (P > 0.05). The implantation rate was comparable in SERa + and SERa- cycles (P > 0.05), but it is higher in the group of only SERa- embryo transfer when compared with the group of mixed SERa + and SERa- embryo transfer (P < 0.05). 159 newborns in SERa + cycles and 140 newborns in SERa- cycles were followed up. Comparable newborn malformation rate was observed between SERa + and SERa- cycles and oocytes (P > 0.05). Logistic regression analysis revealed number of oocytes and total dose of Gn were risk factors for SERa occurrence (aOR = 1.05 and 1.55, P < 0.001). CONCLUSION: Oocyte's SERa is correlated with a number of oocytes retrieved and higher Gn dose, but it does not affect pregnancy outcomes and increase newborn malformation rate.

RESUMEN

AIM: Hepatocellular carcinoma (HCC) has a poor prognosis. Moreover, large HCCs have been commonly observed. We aimed to evaluate the efficacy and safety of drug-eluting beads transarterial chemoembolization (DEB-TACE) combined with conventional TACE (cTACE) for the treatment of patients with unresectable large HCCs (main tumor ≥5 cm in diameter) compared with cTACE alone. METHODS: A retrospective matched cohort study was performed on consecutive patients with unresectable large HCCs who underwent TACE as the initial treatment at the Fujian Medical University Cancer Hospital from May 2017 and March 2019. Fifty-five patients who underwent DEB-TACE combined with cTACE were compared with a case-matched control group of 110 patients who received cTACE alone. We compared the tumor response at 1 and 3 months after TACE, time to progression (TTP), and adverse events between the groups. RESULTS: The objective response rate was higher for the DEB-TACE combined with cTACE group than for the cTACE alone group at 1 (39 of 55 [70.9%] vs. 57 of 110 [51.8%], p = 0.019) and 3 months (27 of 43 [62.8%] vs. 31 of 71 [43.7%], p = 0.048) post-treatment. The DEB-TACE combined with cTACE group also had a significantly longer median TTP than that of the cTACE group (7.2 vs. 5.3 months, p = 0.039). Compared with the cTACE group, occurrences of abdominal pain, nausea/vomiting, and constipation were significantly more frequent in the DEB-TACE combined with cTACE group (p < 0.05). CONCLUSION: Compared with cTACE alone, DEB-TACE combined with cTACE significantly increased the objective response rate at 1 and 3 months after the treatment of unresectable large HCCs, and had a longer TTP, without any significant increase in the number of severe complications.

RESUMEN

Background: Curing hemorrhagic cystitis remains a challenge. We explore a continuous and effective treatment for hemorrhagic radiation cystitis. Methods: The data of patients in 6 provincial cancer hospital urology departments between April 2015 and December 2019 was reviewed retrospectively. Patients were classified as moderate and severe groups. The 5-steps sequential method was adopted. Two groups were initiated with step 1 and step 3 respectively. Step 1 was symptomatic treatment. Thrombin solution or sodium hyaluronate was administrated for bladder irrigation in step 2. Step 3 was transurethral electrocoagulation. Step 4 was interventional embolization. Step 5 was HBO therapy. OABSS was used to assess the improvement of patients' symptoms. The outcome was evaluated after at least 6 months of follow-up. Results: A total of 650 patients (56 men and 594 women), mean age 71.2 years, were enrolled in the 5 steps sequential method. 582 patients were classified as moderate and 68 severe group. In moderate group, the cure rate of step 1 was 61.2% (356/582), 80.4% (468/582) after step 2, 93.1% (542/582) after step 3, 96.2% (560/582) after step 4, and 99.8% (581/582) after step 5. In severe group, the cure rate was 54.4% (37/68) after step 3, 76.5% (52/68) after step 4, and 94.1% (64/68) after the step 5 respectively. The mean OABSS scores of both groups significantly decreased after 5 steps sequential method treatment (P<0.01). Conclusions: Our results show hemorrhagic radiation cystitis can be cured in 5 steps, and the 5 steps sequential method is welcomed and effective. Therapy efficacy depends on the number of steps adopted and the severity of hematuria.

RESUMEN

Recent emerging automotive sensors and innovative technologies in Advanced Driver Assistance Systems (ADAS) increase the safety of driving a vehicle on the road. ADAS enhance road safety by providing early warning signals for drivers and controlling a vehicle accordingly to mitigate a collision. A Rear Cross Traffic (RCT) detection system is an important application of ADAS. Rear-end crashes are a frequently occurring type of collision, and approximately 29.7% of all crashes are rear-ended collisions. The RCT detection system detects obstacles at the rear while the car is backing up. In this paper, a robust sensor fused RCT detection system is proposed. By combining the information from two radars and a wide-angle camera, the locations of the target objects are identified using the proposed sensor fused algorithm. Then, the transferred Convolution Neural Network (CNN) model is used to classify the object type. The experiments show that the proposed sensor fused RCT detection system reduced the processing time 15.34 times faster than the camera-only system. The proposed system has achieved 96.42% accuracy. The experimental results demonstrate that the proposed sensor fused system has robust object detection accuracy and fast processing time, which is vital for deploying the ADAS system.

RESUMEN

BACKGROUND: Hepatocellular carcinoma (HCC) is a common cancer worldwide, with a poor prognosis. Most patients are diagnosed at advanced stages and are only eligible for palliative therapy. Therefore, this study aimed to evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) combined with apatinib (TACE-apatinib) treatment and TACE-alone treatment for Barcelona Clinic Liver Cancer stage C HCC. METHODS: We retrospectively reviewed 80 consecutive patients with BCLC stage C HCC who received TACE-apatinib or TACE-alone as the initial treatment. We compared the clinical and laboratory outcomes, imaging findings at 1 and 3 months after TACE, tumor response, time to progression (TTP), overall survival (OS), and adverse events between both groups. RESULTS: The overall response rate was higher in the TACE-apatinib group than in the TACE-alone group at 1 and 3 months after treatment (66.7% vs 39.6%, respectively, P = 0.020; 45.8% vs 17.6%, respectively, P = 0.021). The median TTP and OS in the TACE-apatinib group were longer than those of the TACE-alone group (TTP: 6.3 months vs 3.5 months, respectively, P = 0.002; OS: 13.0 months vs 9.9 months, respectively, P = 0.041). Apatinib-associated side effects such as hypertension, hand-foot syndrome, oral ulcers, proteinuria, and diarrhea were more prevalent in the TACE-apatinib group than in TACE-alone group (P < 0.05). CONCLUSION: Compared to TACE-alone treatment, TACE-apatinib increased the TTP, OS, and tumor-response rate at 1 and 3 months after treatment of BCLC stage C HCC without any significant increase in severe adverse events.

RESUMEN

Hepatocellular carcinoma (HCC) is one of the most common malignancies and the third leading cause of cancer-related deaths globally. Hepatic arterial infusion chemotherapy (HAIC) treatment is widely accepted as one of the alternative therapeutic modalities for HCC owing to its local control effect and low systemic toxicity. Nevertheless, although accumulating high-quality evidence has displayed the superior survival advantages of HAIC of oxaliplatin, fluorouracil, and leucovorin (HAIC-FOLFOX) compared with standard first-line treatment in different scenarios, the lack of standardization for HAIC procedure and remained controversy limited the proper and safe performance of HAIC treatment in HCC. Therefore, an expert consensus conference was held on March 2023 in Guangzhou, China to review current practices regarding HAIC treatment in patients with HCC and develop widely accepted statements and recommendations. In this article, the latest evidence of HAIC was systematically summarized and the final 22 expert recommendations were proposed, which incorporate the assessment of candidates for HAIC treatment, procedural technique details, therapeutic outcomes, the HAIC-related complications and corresponding treatments, and therapeutic scheme management.

RESUMEN

Osteosarcoma (OS) is the most common primary malignant bone tumor with high metastatic potential and relapse risk. To study the regulatory mechanism of the OS microenvironment, a complex regulatory network involving the ferroptosis- and immune response-related genes remains to be established. In the present study, we determined the effect of a comprehensive evaluation system established on the basis of ferroptosis- and immune-related genes on the immune status, related biomarkers, prognosis, and the potential regulatory networks underlying OS based on the TARGET and Gene Expression Omnibus databases that contain information on OS patients by bioinformatics analyses. We first characterized individual ferroptosis scores and immune scores through gene set variation analysis (GSVA) against TARGET-OS datasets. We then identified differentially expressed genes by score groups. Weighted gene co-expression network analysis was performed to identify the most relevant ferroptosis-related and immune-related gene modules, which facilitated the identification of 327 ferroptosis gene and 306 immune gene candidates. A 4-gene (WAS, CORT, WNT16, and GLB1L2) signature was constructed and valuation using the least absolute shrinkage and selection operator-Cox regression models to effectively predict OS prognosis. The prediction efficiency was further validated by GSE39055. We stratified patients based on the prognostic scoring systems. Eight hub genes (namely CD3D, CD8A, CD3E, IL2, CD2, MYH6, MYH7, and MYL2) were identified, and TF-miRNA target regulatory networks were constructed. Furthermore, Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, gene set enrichment analysis, and GSVA were used to determine the signature's potential pathways and biological functions, which showed that the hub genes were enriched in ferroptosis-associated biological functions and immune-associated molecular mechanisms. Thereafter, we investigated the proportion and infiltration extent of 22 infiltrating immune cells by using CIBERSORT, which revealed significant subgroup differences in CD8 + T cells, M0 macrophages, and M2 macrophages. In conclusion, we determined a new ferroptosis-related and immune-related gene signature for predicting OS patients' prognosis and further explored the ferroptosis and immunity interactions during OS development, which provides insights into the exploration of molecular mechanisms and targeted therapies in patients with OS.

RESUMEN

Background: Unresectable hepatocellular carcinoma (HCC) has a poor prognosis. According to the HCC management guidelines in China, the standard treatment of Barcelona Clinic Liver Cancer (BCLC) stage B or C HCC with portal vein tumour thrombosis (PVTT) is chemoembolization. However, some patients with BCLC stage B or C HCC with PVTT respond poorly to chemoembolization. We aimed to compare tumour responses and survival benefits between patients with unresectable HCC with or without PVTT. Methods: We reviewed 119 consecutive patients with unresectable HCC with PVTT (n = 67) and without PVTT (n = 52) who underwent hepatic arterial infusion of oxaliplatin plus raltitrexed between January 2018 and April 2021. Overall survival, progression-free survival, tumour responses, and adverse events were compared between the groups. Results: There were no significant between-group differences in the objective response rates and median progression-free survival. The median overall survival was significantly longer in the group without PVTT than in that with PVTT (17.0 vs 10.4 months, respectively; P = 0.024). Conclusion: Hepatic arterial infusion of oxaliplatin plus raltitrexed may be efficacious in patients with unresectable HCC with or without PVTT.

RESUMEN

BACKGROUND: Unresectable hepatocellular carcinoma (HCC) has a poor prognosis. We aimed to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) for locally advanced HCC compared to transcatheter arterial chemoembolization (TACE). METHODS: A propensity score-matched cohort study was performed in patients with locally advanced HCC with ≥ 4 tumors or portal vein tumor thrombosis (PVTT) who underwent either HAIC using oxaliplatin plus raltitrexed or TACE at three institutions between June 2015 and December 2021. Overall survival (OS), progression-free survival (PFS), objective response rates (ORR), and adverse events (AEs) were compared between the groups. RESULTS: After propensity score matching, 62 pairs of patients were evaluated. The HAIC group had longer OS (15.0 [95% CI: 12.1-17.9] vs. 9.0 [95% CI: 5.1-12.9] months; P = 0.034), better PFS (6.7 [95% CI: 5.1-8.3] vs. 4.0 [95% CI: 2.6-5.4] months; P = 0.020), and a higher ORR (RECIST 1.1: 54.8% vs. 11.3%; P < 0.001) than the TACE group in the intention-to-treat population. Compared with the TACE group, Grade 1-2 nausea and vomiting occurred significantly more frequently in the HAIC group. CONCLUSION: Compared to TACE, HAIC significantly increased the ORR of locally advanced HCC with multiple tumors or portal invasion and prolonged survival without causing a significant increase in severe AEs.

RESUMEN

Herein, we report an efficient and simple copper-catalyzed oxidative diarylthiolation of maleimides with sulfur powder and aryl boronic acids, in which S powder was used as a substrate and internal oxidant. The corresponding double C-S bonds coupling products were obtained in moderate to high yields under a simple catalytic system. Mechanistic studies indicated that copper-catalyzed radical thiolation of aryl boronic acids with S powder, and the resulting arylthiyl underwent radical addition with double bonds of maleimides.

RESUMEN

OBJECTIVES: To evaluate the predictive value of endometrial thickness (EMT) during in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles for ectopic pregnancy (EP). METHODS: A total of 3068 patients with 3117 fresh IVF/ICSI cycles between January 2016 and February 2019 from the Reproductive Medicine Center of Sun Yat-Sen Memorial Hospital were included in this retrospective study. The patients were divided into an EP group (n = 92) and an intrauterine pregnancy (IUP) group (n = 3025). Multiple logistic regression analysis was conducted to evaluate the EP risk factors. Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of the risk factors for EP and calculate the cutoff value of EMT for EP prediction. RESULTS: The incidence rate of EP was 2.95 % (92/3117). After adjustment for other factors in the logistic regression model, the incidence of EP decreased by 55 % with an EMT > 10 mm compared with an EMT ≤ 10 mm (odds ratio 0.450, 95 % confidence interval 0.296-0.684, P < 0.001). The EMT in the EP group was significantly thinner than that in the live birth (n = 2540) and spontaneous abortion (n = 485) groups (p < 0.017). The cutoff value of EMT for EP prediction was 10.65 mm, with a sensitivity of 59 % and a specificity of 63 %. CONCLUSION: A decreased risk of EP was found among the patients with an EMT > 10 mm prior to embryo transfer. A certain EMT is needed to reduce the incidence of EP.

RESUMEN

PURPOSE: To investigate the efficacy and safety of hepatic arterial infusion (HAI) of oxaliplatin plus raltitrexed in patients with intermediate stage and advanced stage hepatocellular carcinoma (HCC). METHODS: In this phase II, single-arm clinical trial, we enrolled patients aged 18-70 years with intermediate stage and advanced stage HCC, which included patients with HCC at Barcelona Clinic Liver Cancer (BCLC) stage B who experienced transcatheter arterial chemoembolization failure/refractoriness, and those with BCLC stage C with portal vein invasion. We performed HAI with oxaliplatin and raltitrexed. Treatment was repeated every 3 weeks and was discontinued either because of disease progression, unacceptable toxicity levels, or refusal of further treatment. We used Simon's two-stage design. The primary end-point was the objective response rate in accordance with the Response Evaluation Criteria in Solid Tumours. RESULTS: Fifty-one patients were screened between January 5, 2018 and August 7, 2019. Of these, 39 patients (34 men and 5 women; median age, 53 years) were enrolled and included in the intention-to-treat population. Objective response was achieved in 18 (51.4%) of 35 patients in the per-protocol population and in 18 (46.2%) of 39 patients in the intention-to-treat population. Treatment-related grade IV adverse events or deaths were not reported, and the observed grade III adverse events were elevated aspartate aminotransferase levels (5 [12.8%]), elevated alanine aminotransferase levels (1 [2.6%]), leukopenia (1 [2.6%]), thrombocytopaenia (1 [2.6%]) and abdominal infection (1 [2.6%]). CONCLUSION: HAI of oxaliplatin plus raltitrexed showed promising efficacy and acceptable toxicity levels in patients with intermediate and advanced stage HCC, and further evaluation is warranted.

RESUMEN

BACKGROUND: Diabetic foot ulcer (DFU), one of the diabetic complications, brings high burden to diabetic patients. Hyperbaric oxygen therapy (HBOT) has been proven to be an effective clinical method for the treatment of DFU. However, the mechanisms still to be elucidated. METHODS: Diabetic foot mice model was established, and treated with hyperbaric oxygen. Haematoxylin & eosin (H&E) staining and Masson's trichrome staining were used for the analysis of wound healing. Human skin fibroblast (HSF) and human umbilical vein endothelial cell (HUVECS) were exposed to high glucose and hyperbaric oxygen for studying the mechanism of hyperbaric oxygen promoted wound healing in vitro. Wound healing assay, reactive oxygen species (ROS) assay, cell proliferation assay and tube formation assay were used for the analysis of wound healing. Quantitative-polymerase chain reaction (Q-PCR), Western blotting and enzyme-linked immunosorbent assay (ELISA) were used for the analysis of gene expression. RESULTS: HBOT facilitated wound healing in DFU mice model, and promoted the expression of HIF-1α, NF-κB, VEGFA, SDF-1, VEGFR2 and CXCR4. Hyperbaric oxygen promoted the proliferation, migration and ROS production, as well as the expression of SDF-1 and VEGFA in HSF. HBOT stimulated the proliferation, migration and tube formation, as well as the expression of CXCR4 and VEGFR2 in HUVECS. CONCLUSION: Hyperbaric oxygen potentiates angiogenesis and diabetic wound healing by activating HIF-1α signaling, so as to promote the expression of VEGF/SDF-1 in HSF and the expression of VEGFR/CXCR4 in HUVECS, ultimately to promote the proliferation of HSF and the angiogenesis of HUVECS.

RESUMEN

miR-126, an endothelial-specific microRNA, is associated to vascular integrity and angiogenesis. It is well established that angiogenesis plays a critical role in burn wound healing. However, there was a lack of understanding of the mechanism by which miR-126 regulates angiogenesis during burn wound healing. HOX transcript antisense intergenic RNA (HOTAIR) is a well-characterized long non-coding RNA (lncRNA) involved in cell proliferation, apoptosis, migration, and invasion of cancer cells. Sciellin (SCEL), a precursor to the cornified envelope of human keratinocytes, has been shown to inhibit migration and invasion capabilities of colorectal cancer cells. In this study, a cohort of 20 burn wound tissues and paired adjacent normal tissues were collected. LncRNA and messenger RNA expression profiles were screened by microarray analysis in five pairs of samples with mostly increased miR-126 levels. miR-126 was highly expressed in burn wound tissues and human umbilical vein endothelial cells (HUVECs) exposed to heat stress, whereas HOTAIR and SCEL were down-regulated after thermal injury. Bioinformatic analysis, dual luciferase reporter assay, and quantitative real-time PCR were conducted to validate that HOTAIR and SCEL competitively bind to miR-126 to function as the competitive endogenous RNA. miR-126 promoted endothelial cell proliferation, migration, and angiogenesis, but suppressed apoptosis, while HOTAIR and SCEL exerted opposite effects in HUVECs. The biological functions were determined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, Annexin-V-FITC/PI (propidium iodide/fluorescein isothiocyanate) staining, transwell migration, and tube formation assays. Collectively, our study revealed that HOTAIR/miR-126/SCEL axis contributes to burn wound healing through mediating angiogenesis.

RESUMEN

OBJECTIVE: Thermal injury repair is a complex process during which maintaining the proliferation of human dermis fibroblasts (HDFs) and synthesis of extracellular matrix (ECM) plays a critical role. In the present study, we analyzed potential molecular markers and the probable association between differentially-expressed lncRNAs and protein-coding genes within denatured dermis following thermal injury, attempting to provide further insights to thermal injury repair pathogenesis. METHODS AND MAIN RESULTS: We found that the expression of 3940 lncRNAs was increased, while that of 1438 lncRNAs was reduced in the denatured dermis following thermal injury when compared to normal tissue. Of them, 338 were upregulated and 154 were downregulated by more than 128 times. Via cross-check with another microarray profile analysis on differentially-expressed lncRNAs after thermal injury, LINC00302 was found to be downregulated after thermal injury; more importantly, this skin-specially expressed lncRNA is located near a series of genes related to multiple skin inflammation and skin barrier-associated genomes. LINC00302 overexpression promoted the cell viability and the protein levels of α-SMA and Collagen I in HDFs. CONCLUSIONS: In conclusion, mRNAs and lncRNAs could be differentially expressed in the denatured dermis following thermal injury. mRNA and lncRNA regulatory signaling pathways could participate in thermal injury repair pathogenesis. More importantly, LINC00302 may play a critical role in thermal injury repair.

RESUMEN

The aim of this study was to compare the efficacy and safety of 2 different embolic agents, namely gelatin sponge particle (GSP) and Lipiodol, for transarterial chemoembolization (TACE) of unresectable hepatocellular carcinoma (HCC).We retrospectively reviewed 87 consecutive patients with unresectable HCC who underwent Lipiodol TACE with lobaplatin and 87 consecutive patients with unresectable HCC who underwent GSP TACE with lobaplatin between January 2013 and June 2017 in our institution as the initial treatment. Both groups were compared considering the clinical and laboratory outcomes and imaging findings before and after TACE. Tumor response and adverse events were also evaluated.There was significant difference in the rate of complete and overall response between the groups (P = .029 and .001, respectively), specifically when the tumor size was >5 cm (P = .001). The disease control rate was significantly better in the GSP group than in the Lipiodol group (94.3% vs. 86.4%, P = .011). The response differences in higher stages were significant between the 2 groups (P = .035 and .007, respectively). The grades of adverse events were also significantly different between the groups (P = .000).GSP-as an embolic agent in TACE for HCC-could significantly increase the rate of tumor response 1 month after treatment, especially in large tumors, without any significant increase in severe adverse events, when compared to Lipiodol.

RESUMEN

This prospective study aimed to evaluate the efficacy and safety of apatinib in patients with intermediate/advanced hepatocellular carcinoma (HCC).The patients with intermediate/advanced HCC, who met predetermined inclusion and exclusion criteria, underwent oral treatment of apatinib 500 mg daily. The drug-related adverse effects were monitored by regular follow-up and workup including laboratory tests and imaging examinations. Tumor response was assessed by response evaluation criteria in solid tumor criteria. The time to tumor progression (TTP) and overall survival rate (OS) were calculated using the Kaplan-Meier method.A total of 31 patients were enrolled in the study from October 28, 2015 to December 28, 2016. The number of patients with intermediate and advanced HCC was 4 (12.90%) and 27 (87.10%), respectively. The mean tumor size was 9.47 ± 5.48 cm (range: 1.2-19 cm). Vascular invasion was seen in 14 patients (45.16%). A total of 21 (67.74%) patients exhibited extrahepatic metastases. On the basis of first follow-up computed tomography and magnetic resonance imaging at 6 weeks after treatment, 10 (32.26%), 15 (48.39%), and 6 (19.35%) of 31 patients achieved a partial response, stable disease, and progression of disease, respectively. Response rate and disease control rate were 32.26% and 80.65%, respectively. The median TTP was 4.8 months (95% confidence interval: 3.75-5.86 months). Furthermore, 6- and 12-month OS rates were 73.8% and 55.4%, respectively. Grade 3 thrombocytopenia (6.45%) and hypertension (48.39%) were the most common hematologic and nonhematologic toxicities. Grade 3 elevation of either serum total bilirubin or aminotransferase (6.45%) was observed as the top incidence among important indexes of liver function.Our preliminary findings suggest apatinib is a safe and effective therapy in intermediate/advanced HCC patients with high tumor response and survival rates.
