Effect of digital storytelling intervention on resilience, self-efficacy and quality of life among patients with non-small cell lung cancer (NSCLC): A randomized controlled trial.

OBJECTIVE: To verify and compare whether the digital stories could effectively improve the resilience, self-efficacy and quality of life of postoperative NSCLC patients. MATERIALS AND METHODS: A total of 90 participants at baseline were randomly assigned to two groups, 45 patients per group. The intervention group received the digital storytelling intervention which includes 4 videos on different topics: positive psychological quality, cultivating healthy living habits, establishing good social support, and insisting on scientific exercise, whereas the control group received only routine care. The resilience, self-efficacy, and quality of life were assessed at baseline (T0) (within 3 days before surgery), immediately after intervention (T1), one month after intervention (T2), and three months after intervention (T3). A linear mixed effects model was used to test the effects of the digital storytelling interventions on resilience, self-efficacy, and quality of life. RESULTS: The intervention group reported significantly greater improvements in resilience, self-efficacy, and quality of life (all P < 0.001) at follow-ups than the control group after controlling for age, gender, and education level as covariates. Moreover, the sensitivity analysis results are consistent with the per-protocol, that overall time × group interactions effects were significantly different in resilience, self-efficacy, and quality of life (all P < 0.001). CONCLUSION: The digital storytelling intervention based on lung cancer survivors' experience can effectively improve resilience, self-efficacy and quality of life in postoperative lung cancer patients. More comprehensive researches are needed to evaluate the longer-term impacts of the DST and its feasibility for those with more advanced cancer.

The impact of squamous cell transformation on the prognosis of patients treated with radical nephroureterectomy.

BACKGROUND: Limited information is available for guiding the management of upper urinary tract (UUT) urothelial carcinoma with squamous differentiation (UC-SqD). We did not even know about the difference between pure urothelial carcinoma (UC) and UC-SqD in the UUT regardless of treatment policy and prognosis. Instead of direct comparisons against each other, we included the third UUT malignancy, squamous cell carcinoma (SCC). This three-way-race model allows us to more clearly demonstrate the impact of squamous cell transformation on patient outcomes in UUT malignancy. METHODS: We retrospectively analysed 327 patients with UC, UC-SqD, or SCC who underwent radical nephroureterectomy with bladder cuff excision (RNU) at Taichung Veterans General Hospital, Taichung, Taiwan, between January 2006 and December 2013. A Kaplan-Meier survival analysis was used to evaluate the relationship between patient outcomes and histology. Multivariate Cox proportional hazards modelling was also used to predict patient prognoses. RESULTS: The five-year postoperative cancer-specific survival (CSS) rates were 83.6% (UC), 74.4% (UC-SqD), and 55.6% (SCC), and the 5-year recurrence-free survival (RFS) rates were 87.7% (UC), 61.5% (UC-SqD), and 51.9% (SCC). UC patients had significantly better 5-year RFS than UC-SqD and SCC patients (P = 0.001 and P < 0.0001, respectively). Patients with pure UC had significantly better 5-year CSS than SCC patients (P = 0.0045). SCC or UC-SqD did not independently predict disease-specific mortality (HR 0.999, p = 0.999; HR 0.775, p = 0.632, respectively) or disease recurrence compared to pure UC (HR 2.934, p = 0.239; HR 1.422, p = 0.525, respectively). Age, lymphovascular invasion (LVI), and lymph node (LN) status independently predicted CSS, while pathological tumour stage, LN status, and LVI predicted RFS. CONCLUSIONS: SCC and UC-SqD are not independent predictors of survival outcomes in patients with UUT tumours. However, they are associated with other worse prognostic factors. Hence, different treatments are needed for these two conditions, especially for SCC.

Robotic partial nephrectomy for renal tumor: The pentafecta outcomes of a single surgeon experience.

PURPOSE: This study investigated the oncological and functional surgical outcomes for patients with renal tumor who underwent robot-assisted partial nephrectomy (PN) by a single surgeon in Taiwan from 2006 to 2019. METHODS: This retrospective study assessed patients who underwent robot-assisted PN for renal tumor. Patient data were analyzed for age, sex, body mass index, operative time and total ischemic time, surgical margin (positive/negative), and surgical complications. To evaluate functional and oncological outcomes, achievement of trifecta, and pentafecta criteria was used. Trifecta criteria were defined as a negative surgical margin, no postoperative complications, warm ischemia time <25 min. Pentafecta criteria were the trifecta criteria, >90% preservation of estimated glomerular filtration rate (eGFR) preservation, and no stage progression of chronic kidney disease at 1-year follow-up. RESULTS: Of 101 patients who received robot-assisted PN, the most common type of renal tumor was clear cell renal cell carcinoma (RCC) (38%), followed by angiomyolipoma (26%). Patient characteristics were mean age 54.59 ± 13.8 years; mean RENAL Nephrometry score 6.63 ± 2.16; mean operative time 102.34 ± 50.06 min; and warm ischemia time 20.01 ± 14.12 min. The mean eGFR was 104.43 ± 31.73 mL/min/1.73 m2 preoperatively and 89.39 ± 32.3 mL/min/1.73 m2 postoperatively. Pathologic evaluation showed malignant tumors in 57 patients, among whom achievement of trifecta criteria occurred for 39 (68.42%) and pentafecta criteria for 18 (31.57%). Operation time was the only predictor for pentafecta achievement. CONCLUSION: Robotic PN is a safe and effective approach for patients with renal tumor that can preserve most renal function and achieve oncological control. Pentafecta criteria can be used to more clearly define the surgical outcome of RAPN.

Robot-assisted radical prostatectomy using hugo RAS system: The pioneer experience in Taiwan and Northeast Asia.

BACKGROUND: Among the novel robotic platforms, the Hugo RAS system is the second most studied platform, next to the da Vinci system, and we aim to address our experiences in radical prostatectomy (RP) with the Hugo RAS system. METHODS: We recorded our first 12 cases of prostate cancer undergoing RP with the Hugo RAS system. The median console time was 145 min and median hospital stay was 7 days. Hedge' g was applied to search for the cut-off case in four parameters in surgeries. RESULTS: Pre-console preparation was significantly improved after the first seven cases, and the console time was remarkably shortened after the first two cases. The intraoperative pause for trouble shooting was remarkably shortened after the first three cases. CONCLUSIONS: We found that RP with the Hugo RAS system was feasible, and the learning curve was short as surgeons may benefit from the previous experience with the da Vinci system.

[Leonurine inhibits ferroptosis in renal tubular epithelial cells by activating p62/Nrf2/HO-1 signaling pathway].

To investigate the protective effect and the potential mechanism of leonurine(Leo) against erastin-induced ferroptosis in human renal tubular epithelial cells(HK-2 cells), an in vitro erastin-induced ferroptosis model was constructed to detect the cell viability as well as the expressions of ferroptosis-related indexes and signaling pathway-related proteins. HK-2 cells were cultured in vitro, and the effects of Leo on the viability of HK-2 cells at 10, 20, 40, 60, 80 and 100 µmol·L~(-1) were examined by CCK-8 assay to determine the safe dose range of Leo administration. A ferroptosis cell model was induced by erastin, a common ferroptosis inducer, and the appropriate concentrations were screened. CCK-8 assay was used to detect the effects of Leo(20, 40, 80 µmol·L~(-1)) and positive drug ferrostatin-1(Fer-1, 1, 2 µmol·L~(-1)) on the viability of ferroptosis model cells, and the changes of cell morphology were observed by phase contrast microscopy. Then, the optimal concentration of Leo was obtained by Western blot for nuclear factor erythroid 2-related factor 2(Nrf2) activation, and transmission electron microscope was further used to detect the characteristic microscopic morphological changes during ferroptosis. Flow cytometry was performed to detect reactive oxygen species(ROS), and the level of glutathione(GSH) was measured using a GSH assay kit. The expressions of glutathione peroxidase 4(GPX4), p62, and heme oxygenase 1(HO-1) in each group were quantified by Western blot. RESULTS:: showed that Leo had no side effects on the viability of normal HK-2 cells in the concentration range of 10-100 µmol·L~(-1). The viability of HK-2 cells decreased as the concentration of erastin increased, and 5 µmol·L~(-1) erastin significantly induced ferroptosis in the cells. Compared with the model group, Leo dose-dependently increased cell via-bility and improved cell morphology, and 80 µmol·L~(-1) Leo promoted the translocation of Nrf2 from the cytoplasm to the nucleus. Further studies revealed that Leo remarkably alleviated the characteristic microstructural damage of ferroptosis cells caused by erastin, inhibited the release of intracellular ROS, elevated GSH and GPX4, promoted the nuclear translocation of Nrf2, and significantly upregulated the expression of p62 and HO-1 proteins. In conclusion, Leo exerted a protective effect on erastin-induced ferroptosis in HK-2 cells, which might be associated with its anti-oxidative stress by activating p62/Nrf2/HO-1 signaling pathway.

An-Luo-Hua-Xian Pill Improves the Regression of Liver Fibrosis in Chronic Hepatitis B Patients Treated with Entecavir.

Background and Aims: Chronic hepatitis B (CHB) can cause liver fibrosis and lead to cirrhosis and cancer. As the effectiveness of antiviral therapy to reverse liver fibrosis is limited, We aimed to evaluate the effect of An-Luo-Hua-Xian pill (ALHX) on fibrosis regression in CHB patients treated with entecavir (ETV). Methods: Treatment-naïve patients with CHB were randomly treated with ETV alone or combined with ALHX (ETV+ALHX) between October 1, 2013 and December 31, 2020. Demographic, laboratory, and liver histology data before and after 78 weeks of treatment were collected. The Ishak fibrosis score (F) was used and fibrosis regression required a decrease in F of ≥1 after treatment. Results: A total of 780 patients were enrolled, and 394 with a second liver biopsy after treatment were included in the per-protocol population, 132 in ETV group and 262 in ETV+ALHX group. After 78 weeks of treatment, the fibrosis regression rate in the ETV+ALHX group was significantly higher than that of the ETV group at baseline F≥3 patients: 124/211 (58.8%) vs. 45/98 (45.9%), p=0.035. The percentage of patients with a decreased liver stiffness measurement (LSM) was higher in the ETV+ALHX group: 156/211 (73.9%) vs. 62/98 (63.%), p=0.056. Logistic regression analysis showed that ETV combined with ALHX was associated with fibrosis regression [odds ratio (OR)=1.94, p=0.018], and a family history of hepatocellular carcinoma was on the contrary. (OR=0.41, p=0.031). Conclusions: ETV combined with ALHX increased liver fibrosis regression in CHB patients.

Joint Effects of Prenatal Folic Acid Supplement with Prenatal Multivitamin and Iron Supplement on Obesity in Preschoolers Born SGA: Sex Specific Difference.

Prenatal maternal nutrient supplementation has been reported to be associated with offspring obesity, but the reports are inconsistent and have mainly ignored the differences between the total children population and children born small for gestational age (SGA). This study aimed to examine the joint effects of folic acid, iron, and multivitamin supplementation during pregnancy on the risk of obesity in preschoolers born SGA. A total of 8918 children aged 3-6.5 years born SGA were recruited from Longhua District in Shenzhen of China in 2021. Their mothers completed a structured questionnaire about the child's and parents' socio-demographic characteristics, maternal prepregnant obesity, and mothers' prenatal supplementation of folic acid, iron, and multivitamin. In addition, the children's current weight and height were measured by trained nurses. Logistic regression models were used to analyze the associations between prenatal supplementations and the current presence of childhood obesity. After controlling for potential confounders, the results of the logistic regression analysis showed that prenatal supplement of folic acid (OR = 0.72, 95% CI = 0.55~0.93) was associated with a lower likelihood of being an obese preschooler born SGA. In contrast, the ingestion of multivitamin or iron supplements during pregnancy did not seem to be related to the likelihood of childhood obesity in preschoolers born SGA. Moreover, cross-over analysis of prenatal folic acid and multivitamin obtained significant negative associations of prenatal folic acid supplement only (OR = 0.73, 95% CI = 0.55~0.97) and combination supplement of folic acid and multivitamin (OR = 0.67, 95% CI = 0.50~0.90) with obesity of preschoolers born SGA; while the cross-over analysis of prenatal folic acid and iron observed significant negative associations between obesity of preschoolers born SGA and a combination supplement of folic acid and iron (OR = 0.70, 95% CI = 0.52~0.96). Furthermore, the aforementioned significant associations were only found in girls and not in boys when the analyses were stratified by sex. Our findings suggest that the prenatal folic acid supplementation may decrease the risk of obesity in preschool girls born SGA, and that this effect may be modified by prenatal multivitamin or iron supplementation.

[Spatial and temporal variations of vegetation phenology and its response to urbanization in central Yunnan urban agglomeration, Southwest China]. / æ»‡ä¸­åŸŽå¸‚ç¾¤æ¤è¢«ç‰©å€™æ—¶ç©ºå˜åŒ–åŠå ¶å¯¹åŸŽå¸‚åŒ–çš„å“åº”.

Vegetation phenology is an important sensor that responds to environmental changes. Based on MOD13Q1 EVI data, we used the dynamic threshold method to extract vegetation phenological parameters of the central Yunnan urban agglomeration from 2001 to 2020, namely the start of growing season, the end of growing season, and the length of growing season, aiming to reveal the spatiotemporal variations in vegetation phenology and urban-rural differences. The results showed that vegetation phenology of the central Yunnan urban agglomeration from 2001 to 2020 generally showed a phenomenon of delayed start of growing season, delayed the end of growing season (0.66 days per year), and prolonged growing season. Compared with suburban and rural areas, growing season in urban areas in the past 20 years had started earlier (1.05 days per year), ended later (0.91 days per year), and thus growing season had been prolonged (1.79 days per year). Vegetation phenology showed significant difference on the gradient of urban, suburban, and rural areas. The start and the end of growing season of urban vegetation were the earliest, and the length of growing season was the longest, with the most significant changes in the urban areas and within the range of 0-2 km outward. The start of growing season in urban area was significantly earlier, the end of growing season was significantly delayed, and length of growing season was prolonged significantly with the increase of population density, per capita GDP, and the proportion of built-up area. The sensitivity of different phenological periods of vegetation and their duration to environmental changes varied on the gradient of urban, suburban and rural areas. Population density and proportion of built-up area in the study area played an important role in delaying the end of growing season of vegetation in the central Yunnan urban agglomeration.

Long non-coding RNA MALAT1 promotes Th2 differentiation by regulating microRNA-135b-5p/GATA-3 axis in children with allergic rhinitis.

Allergic rhinitis (AR) threatens patient survival. CD4+ T cells play key roles in AR progression. Long non-coding RNAs (lncRNAs) are key regulators of cell differentiation. Therefore, we investigated the molecular mechanism of the lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in AR. Expression levels of MALAT1, microRNA (miR)-135b-5p, interleukin-4 (IL-4), and GATA-binding protein 3 (GATA-3) in the nasal mucosa of AR patients were quantified. CD4+ T cells were isolated from the peripheral blood of healthy volunteers and treated with ovalbumin (OVA) and Th2 inducers. After MALAT1 and miR-135b-5p levels changed in CD4+ T cells, the proportion of IL-4-expressing cells and the levels of IL-4 and GATA-3 in OVA-induced CD4+ T cells were determined. Binding relationships among MALAT1, miR-135b-5p, and GATA-3 were predicted and verified. Rescue experiments were performed to confirm the role of the MALAT1/miR-135b-5p/GATA-3 axis in Th2 differentiation of CD4+ T cells. MALAT1, IL-4, and GATA-3 expression was upregulated, whereas miR-135b-5p expression was downregulated, in patients with AR. MALAT1 knockdown or miR-135b-5p overexpression in CD4+ T cells notably decreased the proportion of IL-4-expressing cells and downregulated GATA-3 and IL-4 expression in OVA-induced CD4+ T cells. MALAT1 and GATA-3 exhibited competitive binding toward miR-135b-5p. MALAT1 facilitated CD4+ T cell Th2 differentiation via the miR-135b-5p/GATA-3 axis. MALAT1 facilitated AR development by facilitating CD4+ T cell Th2 differentiation via the miR-135b-5p/GATA-3 axis. This study may provide guidance for clinical treatment of AR.

Design, synthesis and in vitro biological evaluation of marine phidianidine derivatives as potential anti-inflammatory agents.

Phidianidines A and B are novel marine indole alkaloids with various biological activities. Based on their potential anti-inflammatory properties, a series of phidianidine derivatives were designed, synthesized, and tested for their effects on IL-17A production in PMA/ionomycin-stimulated T-cell-lymphoma EL-4 cells. Compounds 9a and 22c exhibited excellent anti-inflammatory activity and low toxicity, with IC50 values of 7.7 µM and 5.3 µM for IL-17A production in PMA/ionomycin-stimulated EL-4 cells, respectively. Further mechanistic study showed that 9a could decrease the STAT3 phosphorylation at Y705 to inhibit IL-17A production in EL-4 cells, indicating its ability of preventing the differentiation of Th17 cells and their possible function. This research may give an insight for the discovery of marine indole alkaloid derived anti-inflammatory drug leads for the treatment of T cell-mediated diseases.

Critical window for the association between prenatal environmental tobacco smoke exposure and preterm birth.

Although environmental tobacco smoke (ETS) exposure is considered to be a severe public health problem and a modifiable risk factor for preterm birth (PTB), we still lack a comprehensive understanding of the PTB risk associated with trimester-specific prenatal ETS exposure. This study aimed to examine the accumulation of risk across trimester ETS exposure and the critical window of the association between maternal ETS exposure during pregnancy and PTB. A total of 63,038 mother-child pairs were involved in the analysis of the 2017 survey of Longhua Child Cohort Study. Information about socio-demographic characteristics, prenatal ETS exposure, and birth outcomes were collected using a self-report questionnaire. A series of logistic regression models were employed to assess the associations between prenatal ETS exposure and PTB. We found that maternal ETS exposure during pregnancy significantly increased the risk of PTB and this association increased with both the average level of daily ETS exposure and the number of trimesters of ETS exposure. Moreover, mothers who were initially exposed to ETS in the 1st trimester of pregnancy had significant higher risk of PTB (OR = 1.34, 95% CI: 1.25-1.44). Furthermore, mothers exposed to ETS in the 1st trimester only (OR = 1.26, 95%CI: 1.04-1.50), in both 1st and 2nd trimester (OR = 1.35, 95%CI: 1.08-1.67) and throughout pregnancy (OR = 1.35, 95%CI: 1.24-1.46) experienced a significantly high risk of PTB. Prenatal maternal ETS exposure during only the 2nd trimester also resulted in a high risk of PTB with marginal significance (OR = 1.33, 95% CI:0.78-2.13). To conclude, the 1st and early 2nd trimester might be the critical window for prenatal ETS exposure causing PTB.

Selaginellin Inhibits Melanogenesis via the MAPK Signaling Pathway.

Hyperpigmented skin diseases such as melasma, freckles, and melanosis usually mar the appearance of patients. Traditional herbal medicines are highly accepted in inhibiting skin pigmentation, with advantages of high efficiency, low cost, and low side effects. Selaginellin (SEL), one of the active compounds of selaginella, has been proved to be exhibit antineoplastic, antioxidant, antisenescence, and antiapoptosis activities. In this study, we found that SEL can inhibit melanogenesis in vitro and in vivo. A mechanism study found that SEL inhibits melanogenesis through inhibiting the mitogen-activated protein kinase (MAPK) signaling pathway, then down-regulating the expression of microphthalmia-associated transcription factor (MITF) and downstream genes tyrosinase (TYR) and tyrosinase-related protein 2 (TYRP2). UVB-activated paracrine function of fibroblasts and keratinocytes promotes melanogenesis of melanocytes. Interestingly, SEL antagonizes UVB-activated paracrine function of fibroblasts and keratinocytes. These findings indicate that SEL can be a potential whitening compound to inhibit melanogenesis.

Radium-223 for metastatic, castration-resistant prostate cancer: A retrospective chart review study of real-world use in a tertiary hospital in Taiwan.

BACKGROUND: Radium-223 is an alpha-emitting, bone-targeting radiopharmaceutical that confers a survival benefit in patients with confirmed bone-metastatic, castration-resistant prostate cancer with no visceral metastases. We studied real-world use of radium-223 in eligible patients from a tertiary hospital. METHODS: We retrospectively collected clinical data of patients treated with radium-223 in Tungs' Taichung MetroHarbor Hospital by chart review. Data included biochemical parameters, pain scores, other prostate cancer treatments received and adverse events (AEs). RESULTS: Of 36 patients included in the study, 12 patients received radium-223 as first-line therapy, 11 as second-line treatment and 13 as third-line treatment. Prostate-specific antigen significantly increased from baseline in patients who received radium-223 as third-line treatment and in patients who received radium-223 post-chemotherapy. Pain scores significantly decreased when radium-223 was given as second-line and as third-line treatment. In the patients who were naive to novel anti-hormone (NAH) therapy and chemotherapy, mean alkaline phosphatase level significantly decreased from baseline. The most common AE was anemia, found in 16.7% of patients. CONCLUSION: Radium-223 had early biochemical benefits, while in the later stages of the disease, it reduced bone pain in this real-world cohort of chemotherapy-naive, NAH-naive patients, and patients with prior therapy, from a tertiary institution in Taiwan.

Role of HMGB1 in TNF-α Combined with Z-VAD-fmk-Induced L929 Cells Necroptosis.

The present study established a necroptosis model in vitro and investigated the role of HMGB1 in cell necroptosis. A combination of tumor necrosis factor-α and z-VAD-fmk was used to induce necroptosis in L929 cells with necroptosis inhibitor necrostatin-1 applied as an intervention. Flow cytometry and transmission electron microscopy (TEM) were used to measure cell necroptosis. Western blotting assay was applied to detect the expression of receptor-interacting serine/threonine-protein kinase 3 (RIPK3), mixed lineage kinase domain-like pseudokinase (MLKL) and HMGB1. Co-immunoprecipitation (Co-IP) assay was used to confirm the interaction between HMGB1 and RIPK3. Our study demonstrated that HMGB1 migrated from the nucleus to the cytoplasm at the onset of necroptosis and was subsequently released passively to the extracellular matrix. Further experiments determined that the binding of HMGB1 with RIPK3 in the cytoplasm was loose during necroptosis. By contrast, when necroptosis was inhibited, the interaction in the cytoplasm was tight suggesting that this association between HMGB1 and RIPK3 might affect its occurrence. In conclusion, the transfer of HMGB1 from nucleus to cytoplasm, and its interaction with RIPK3 might be potentially involved in necroptosis.

Diffusive Ki67 and vimentin are associated with worse recurrence-free survival of upper tract urothelial carcinoma: A retrospective cohort study from bench to bedside.

OBJECTIVES: This study aimed to determine the prognostic values of Ki67 and vimentin in upper tract urothelial carcinoma (UTUC) after extirpative surgery. METHODS AND MATERIALS: Between 2014 and 2019, patients diagnosed with UTUC and receiving radical nephroureterectomy were included retrospectively. Nuclear MIB-1 clones and cytoplasmic VIM 3B4 clones were used to assess Ki67 and vimentin levels, respectively. A unified reading protocol was applied, and the expression level was read by a single pathologist. Receiver operating characteristic curves were utilized to determine the best threshold for Ki67 and vimentin regarding recurrence, and this level was set as the diffusive level. The outcome of recurrence-free survival (RFS) was analyzed via a Cox regression model with univariable and multivariable approaches. Survival outcomes were analyzed via Kaplan-Meier (KM) curves. RESULTS: A total of 247 patients were included, and the mean follow-up was 29.90 ± 6.80 months. Diffusive thresholds were 17.5% for both Ki67 and vimentin. Under multivariable Cox regression, diffusive Ki67 (hazard ratio: 4.20 [2.39-7.37], P < 0.001) and diffusive vimentin (hazard ratio: 5.34 [3.10-9.22], P < 0.001) were significant prognostic indicators of worse RFS. Diffusive Ki67 was accompanied by diffusive vimentin (chi square with Yates' correction, P = 0.015), and vice versa. In the KM curve, there was no difference between diffusive Ki67/nondiffusive vimentin and nondiffusive Ki67/diffusive vimentin (log-rank test, P = 0.073). Significant differences (log-rank test, P < 0.001) were seen in different combinations of diffusive Ki67/vimentin (Mean RFS: 19.76 [18.56-20.96] months), only one diffusive in Ki67 or vimentin (Mean RFS: 22.94 [21.88-24.00] months), and nondiffusive Ki67/vimentin (Mean RFS: 32.96 [32.43-33.50] months). CONCLUSIONS: Diffusive Ki67 and vimentin were related to each other, and they exerted equivalent and synergic effects on predicting worse RFS in UTUC.

Comprehensive Analysis of Differentially Expressed lncRNAs miRNAs and mRNA and Their ceRNA Network of Patients With Rare-Earth Pneumoconiosis.

Rare-earth pneumoconiosis (REP) is the main occupational disease of rare earth exposed workers and there is no specific treatment. In this study, we performed high-throughput sequencing on the plasma of nine REP to describe and analyze the expression profiles of long non-coding RNA (lncRNA), micro RNA (miRNA) and mRNA and investigate their regulatory networks. Our results identified a total of 125 lncRNAs, 5 miRNAs, and 82 mRNAs were differentially expressed in the plasma of patients with REP. Furthermore, Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were used to analyze the differentially expressed non-coding RNAs (ncRNA). We found the differential expression of ncRNA are mainly related to the response of cells to stimulation, Hedgehog signaling pathway and so on. We also constructed lncRNA-miRNA-mRNA networks to further explore their underlying mechanism and possible relationships in REP. We found that in the competitive endogenous RNA (ceRNA) networks, lncRNA acts as a sponge of miRNA to regulate the target gene. The expression results were verified by qRT-PCR and the protein interaction networks of differentially expressed genes were constructed via the STRING database. OncoLnc online platform was used to do the lung cancer survival analysis among the top five mRNA analyzed by Protein-protein interaction (PPI) network analysis. We found miR-16-2-3p may used as biomarker for REP, because it is closely related to the occurrence and prognosis of REP through inflammatory reaction and in lung squamous cell carcinoma, its expression levels were positively correlated with the overall survival rate of patients.

Discovery of new tranylcypromine derivatives as highly potent LSD1 inhibitors.

Tranylcypromine (TCP)-based structural modifications lead to the discovery of new LSD1 inhibitors, of which compounds 26b and 29b effectively inhibit LSD1 with the IC50 values of 17 and 11 nM, respectively and also show good selectivity over MAO-B. Mechanistic studies showed that compound 29b concentration-dependently induced H3K4me1/2 accumulation in LSD1 overexpressed MGC-803 cells and also inhibited metastasis of MGC-803 cells. Collectively, both compounds could be promising lead compounds for further investigation.

Biochemical recurrence of pathological T2+ localized prostate cancer after robotic-assisted radical prostatectomy: A 10-year surveillance.

BACKGROUND: pT2+ prostate cancer (PCa), a term first used in 2004, refers to organ-confined PCa characterized by a positive surgical margin (PSM) without extracapsular extension. Patients with a PSM are vulnerable to biochemical recurrence (BCR) following radical prostatectomy (RP); however, whether adjuvant radiotherapy (aRT) is imperative to PSM after RP remains controversial. This study had the longest follow-up on pT2+ PCa after robotic-assisted RP since 2004. Moreover, we discussed our viewpoints on pT2+ PCa based on real-world experiences. AIM: To conclude a 10-year surveillance on pT2+ PCa and compare our results with those of the published literature. METHODS: Forty-eight patients who underwent robotic-assisted RP between 2008 and 2011 were enrolled. Two serial tests of prostate specific antigen (PSA) ≥ 0.2 ng/mL were defined as BCR. Various designed factors were analyzed using statistical tools for BCR risk. SAS 9.4 was applied and significance was defined as P < 0.05. Univariate, multivariate, linear regression, and receiver operating characteristic (ROC) curve analyses were performed for statistical analyses. RESULTS: With a median follow-up period of 9 years, 25 (52%) patients had BCR (BCR group), and the remaining 23 (48%) patients did not (non-BCR group). The median time for BCR test was 4 years from the first postoperative PSA nadir. Preoperative PSA was significantly different between the BCR and non-BCR groups (P < 0.001), and ROC curve analysis of preoperative PSA suggested a cut-off value of 19.09 ng/mL (sensitivity, 0.600; specificity: 0.739). The linear regression analysis showed no correlation between time to BCR and preoperative PSA (Pearson's correlation, 0.13; adjusted R 2 = 0.026). CONCLUSION: Robotic-assisted RP in pT2+ PCa of worse conditions can provide better BCR-free survival. A surgical technique limiting the PSM in favorable situations is warranted to lower the pT2+ PCa BCR rate. Preoperative PSA cut-off value of 19.09 ng/mL is a predictive factor for BCR. Based on our experiences and review of the literature, we do not recommend routine aRT for pT2+ PCa.

Correlation analysis of IL-11 polymorphisms and Hirschsprung disease subtype susceptibility in Southern Chinese Children.

BACKGROUND: Hirschsprung disease (HSCR) is a hereditary defect, which is characterized by the absence of enteric ganglia and is frequently concurrent with Hirschsprung-associated enterocolitis (HAEC). However, the pathogenesis for HSCR is complicated and remains unclear. Recent studies have shown that pro-inflammatory cytokines such as interleukin-11 (IL-11) are involved in the enteric nervous system's progress. It was found that IL-11 SNPs (rs8104023 and rs4252546) are associated with HSCR in the Korean population waiting for replication in an independent cohort. This study evaluated the relationship between IL-11 and the susceptibility of patients to HSCR by performing subphenotype interaction examination, HAEC pre-/post-surgical patient-only association analysis, and independence testing. METHODS: In this study, a cohort consisting of children from Southern China, comprising 1470 cases and 1473 controls, was chosen to examine the relationship between two polymorphisms (rs8104023 and rs4252546 in IL-11) and susceptibility to HSCR by replication research, subphenotype association analysis, and independence testing. RESULTS: The results showed that IL-11 gene polymorphisms (rs8104023 and rs4252546) are not associated with the risk of HSCR in the Chinese population. The results of both short-segment and long-segment (S-HSCR and L-HSCR) surgery (3.34 ≤ OR ≤ 4.05, 0.02 ≤ P ≤ 0.04) showed that single nucleotide polymorphisms (SNP) rs8104023 is associated with susceptibility to HAEC. CONCLUSIONS: This study explored the relationship between genetic polymorphisms and susceptibility to HAEC in HSCR subtypes for the first time. These findings should be replicated in a larger and multicentre study.

Robotic Incisional Hernia Repair After Robotic-assisted Radical Prostatectomy (RARP): A 3-port Approach.

BACKGROUND/AIM: Incisional hernia is a complication that occurs occasionally, and surgical intervention is required to prevent more severe sequela. While there are several options for management, robotic-assisted incisional repair has not been well discussed yet. We herein report a case series of 10 patients who underwent robotic-assisted incisional hernia repair (RIHR) after robotic-assisted radical prostatectomy (RARP). The aim of the study was to examine the feasibility of incisional hernia repair with da Vinci® robotics. PATIENTS AND METHODS: We recruited patients from a group of 2,000 consecutive patients who underwent RARP from December, 2005 to June, 2020 by a single surgeon. Patient characteristics included age, body mass index (BMI), PSA level, pathology Gleason score, and pathology TNM staging. The variants regarding the patients' incisional hernia included incisional hernia occurrence time after RARP, defect size, operation time, console time, blood loss, and follow-up time after the herniation occurrence. Furthermore, we established a defect size of 3x2 cm2 as the cutoff value for using mesh reinforcement or not. RESULTS: The mean defect area was 27.7 cm2, and the average operative time was 114.8 min, with a mean console time of 87 min. Blood loss was 32.5 ml, and the hospital stay for all patients was 3 days without complications. The mean follow-up period was 29.5 months, with no recurrence. CONCLUSION: RIHR is a feasible surgical method that is not inferior to the traditional open or laparoscopic repair. Furthermore, RIHR can possibly lessen the burden of both the surgeon and patient.
