Relationship between social jetlag and body mass index in nurses working shift schedules: a cross-sectional study.

This study aimed to explore the relationship between shift-working nurses' social jetlag and body mass index (BMI) and provide a theoretical basis for nursing managers to develop appropriate health interventions. Shift work is unavoidable in nursing and is associated with circadian rhythm disorders. Social jetlag is prevalent in shift-working nurses and is associated with adverse health outcomes (particularly metabolism-related indicators). BMI is a significant metabolic indicator, and research has demonstrated its effectiveness in predicting the formation of metabolic syndrome. The relationship between social jetlag and BMI can be explained by considering physiological, psychological, and behavioral factors. However, most studies on social jetlag and health status are focused on non-shift nurse populations, with fewer studies on shift workers. Five tertiary hospitals located at similar latitudes in Southwest China were selected for the study. We surveyed 429 shift-working nurses using sociodemographic data, the Munich Chronotype Questionnaire for Shift Workers, and BMI. The restricted cubic spline model was used to analyze the relationship between social jetlag and BMI among shift-working nurses, and segmented linear regression was performed around the inflection point using multiple linear regression analysis. The results revealed that social jetlag (82.0 [85.0] min) was experienced by 64.6% of the shift-working nurses. After controlling for confounding variables, the model with seven knots had the lowest accepted Akaike information criterion value, and there was a U-shaped relationship between shift-working nurses' BMI and social jetlag in this model; its inflection (lowest) point of 20.7 was considered the cut-off point. Segmented regression showed that for BMI < 20.7, BMI was significantly negative with standardized social jetlag; whereas with BMI > 20.7, BMI was significantly positive with standardized social jetlag. BMI has a U-shaped relationship with social jetlag, and attention should be paid to overweight or underweight shift-working nurses to detect early circadian rhythm disorder. Shift-working nurses with high social jetlag tended to have higher/lower BMI, which should be further investigated in the future, to minimize metabolic diseases among them.

68 Ga-DOTATATE PET/CT Detected Bone Metastasis Earlier Than 68 Ga-FAPI PET/CT and 99m Tc-MDP Bone Scintigraphy in a Patient With Nasopharyngeal Carcinoma.

ABSTRACT: A 53-year-old man with newly diagnosed nasopharyngeal carcinoma (NPC) underwent 99m Tc-MDP bone scintigraphy for the potential bone metastases, and paired 68 Ga-DOTATATE and 68 Ga-FAPI PET/CT for initial staging. 68 Ga-DOTATATE PET/CT identified 2 abnormal foci with increased tracer uptake in the cervical vertebra and the ilium, whereas 68 Ga-FAPI PET/CT and bone scan detected only the ilium lesion. A subsequent biopsy confirmed NPC metastasis in the ilium. Furthermore, baseline and follow-up bone scintigraphy revealed that the positive lesion in the cervical vertebra, as indicated in 68 Ga-DOTATATE PET/CT, was also a bone metastasis. This case highlighted the potential superiority of 68 Ga-DOTATATE in NPC.

Enhanced nitrogen removal by an isolated aerobic denitrifying strain in a vertical-flow constructed wetland.

The addition of bacterial agents is an effective method for improving nitrogen removal from wetlands. Herein, an aerobic denitrifier, RC-15, was added to a vertical-flow constructed wetland (CW), and the presence of functional genes and microbial communities was investigated at different CW depths. For the RC-15-treated CW, the removal of NO3- and TN during the process was significantly greater than in the control. Quantitative PCR revealed that nirS is a dominant denitrifying gene for treating WWTP tailwater. Moreover, the presence of the RC-15 strain significantly enhanced the abundance of the napA gene and nirK gene in the CWs. The napA gene was concentrated in the upper layer of the CWs, and the nirK gene was concentrated in the middle and bottom layers. Compared to the control, the addition of the bacterial agent Trial resulted in a more diverse denitrification pathway, a greater abundance of 16Sr RNA, and a greater number of denitrifying strains. According to the microbial community analysis, Proteobacteria and Chloroflexi dominated denitrification in the CWs. Greater abundances of Thauera, Aeromonas and Ardenticatenales were found at the genus level, indicating that these genera have potential applications in future nitrogen removal projects.

Healthcare provider perceptions and reported practices regarding opioid prescription for patients with chronic cancer pain.

PURPOSE: Data indicates that clinicians might be under-prescribing opioids for patients with chronic cancer pain, and this could impact adequate pain management. Few studies have sought to understand healthcare provider (HCP) perceptions and practices regarding the prescription of opioids for chronic cancer pain. We assessed HCP perceptions and practices regarding opioid prescription for patients with chronic cancer pain since the onset of the COVID-19 pandemic. METHODS: An anonymous cross-sectional survey was conducted among 186 HCPs who attended an opioid educational event in April 2021 and 2022. RESULTS: Sixty-one out of 143 (44%) opioid prescribers reported reluctance to prescribe opioids for chronic cancer pain. In a multivariate logistic model, younger participants (log OR - 0.04, 95% CI - 0.085, - 0.004; p = 0.033) and pain medicine clinicians (log OR - 1.89, CI - 3.931, - 0.286; p = 0.034) were less reluctant, whereas providers who worry about non-medical opioid use were more reluctant to prescribe opioids (log OR 1.58 95% CI 0.77-2.43; p < 0.001). Fifty-three out of 143 (37%) prescribers had experienced increased challenges regarding opioid dispensing at pharmacies, and 84/179 (47%) of all respondents reported similar experience by their patients. Fifty-four out of 178(30%) were aware of opioid-related harmful incidents to patients or their families, including incidents attributed to opioid misuse by a household or family member. CONCLUSION: A considerable number of opioid prescribers were reluctant to prescribe opioids for patients with chronic cancer pain. Many reported challenges regarding dispensing of opioids at the pharmacies. These may be unintended consequences of policies to address the opioid crisis. Future measures should focus on addressing regulatory barriers without undermining the gains already made to combat the opioid crisis.

TRIM14 Overexpression Induces Chemoresistance and Malignant Behaviors of Hepatocellular Carcinoma Cells by Activating the STAT3/HIF-1α Pathway.

Members of the tripartite motif (TRIM)-containing protein family have been found to be involved in the progression of hepatocellular carcinoma (HCC). TRIM14 exerts a promotive impact on several cancers. This study aimed to explore the function and mechanism of TRIM14 in HCC. TRIM14 expression in HCC tissues and HCC cell lines was detected. The overexpression or knockdown model of TRIM14 was established in HCC cell lines. Cell Counting Kit-8 (CCK-8) assay, flow cytometry, Transwell assay, RT-PCR, Western blot, and immunofluorescence were performed to verify the influence of TRIM14 on cell proliferation, sensitivity to chemotherapy drugs, apoptosis, migration, invasion, and autophagy. A xenograft tumor model was used to confirm the impact of TRIM14 on tumor cell growth. As shown by the data, TRIM14 level was notably higher in the tumor tissues of HCC patients than in the adjacent tissues. The overall survival rate of patients with a high TRIM14 expression was relatively lower than that of patients with a low TRIM14 expression. TRIM14 upregulation enhanced the proliferation, autophagy, migration, and invasion of HCC cells and chemoresistant HCC cells and decreased apoptosis. TRIM14 knockdown contributed to the opposite effects. In in vivo experiments, TRIM14 upregulation bolstered tumor growth. Western blot analysis revealed that TRIM14 upregulation boosted signal transducer and activator of transcription3 (STAT3) and hypoxia-inducible factor-1alpha (HIF-1α) expression, and TRIM14 knockdown suppressed their expression. Moreover, repressing STAT3 and HIF-1α could mitigate the tumor-promoting role of TRIM14 in HCC cells. Overall, TRIM14 facilitated malignant HCC development and induced chemoresistance in HCC cells by activating the STAT3/HIF-1α axis.

Estimating causal effects with hidden confounding using instrumental variables and environments.

Recent works have proposed regression models which are invariant across data collection environments [24, 20, 11, 16, 8]. These estimators often have a causal interpretation under conditions on the environments and type of invariance imposed. One recent example, the Causal Dantzig (CD), is consistent under hidden confounding and represents an alternative to classical instrumental variable estimators such as Two Stage Least Squares (TSLS). In this work we derive the CD as a generalized method of moments (GMM) estimator. The GMM representation leads to several practical results, including 1) creation of the Generalized Causal Dantzig (GCD) estimator which can be applied to problems with continuous environments where the CD cannot be fit 2) a Hybrid (GCD-TSLS combination) estimator which has properties superior to GCD or TSLS alone 3) straightforward asymptotic results for all methods using GMM theory. We compare the CD, GCD, TSLS, and Hybrid estimators in simulations and an application to a Flow Cytometry data set. The newly proposed GCD and Hybrid estimators have superior performance to existing methods in many settings.

LncRNA-EWSAT1 promotes hepatocellular carcinoma metastasis via activation of the Src-YAP signaling axis.

Regardless of the improvements in diagnostic and therapeutic methods, the clinical outcomes of hepatocellular carcinoma (HCC) patients remain poor. Although accumulating evidence indicates that lncRNAs (long noncoding RNAs) are essential within the control of tumorigenesis and the metastasis of cancer, the underlying mechanisms remain largely unknown. This work explored the pattern of expression and functional significance of a newly found lncRNA, Ewing sarcoma-associated transcript 1 (EWSAT1), in HCC metastasis. The results indicated that EWSAT1 was upregulated significantly in HCC relative to that in normal tissues and was correlated with an aggressive phenotype and low patient survival. Functional experiments demonstrated that EWSAT1 could promote proliferation and HCC cell metastasis both in vitro and in vivo. Mechanistically, EWSAT1 binds directly to Yes-associated protein (YAP), promotes Sarcoma gene (Src)-induced phosphorylation of YAP, facilitates nuclear translocation of YAP, and consequently, activates the transcription of Hippo-YAP signaling target genes involved in cancer evolution. This study found that EWSAT1 plays a crucial role in HCC metastasis and that it has the potential to be a prognosis biomarker and a target for therapeutics.

The effectiveness of psychoeducational interventions on family function among families after stroke: A meta-analysis.

AIMS: This meta-analysis aimed to synthesize the available evidence on the effectiveness of psychoeducational interventions on family function among families after stroke. BACKGROUND: Family function may be improved by psychoeducational intervention, but findings about the effect of psychoeducation on family function among families after stroke have been mixed. METHODS: This was a meta-analysis carried out by searching five international electronic databases, including Cochrane Library, PubMed, EMBASE, Web of Science and CINAHL, as well as four national electronic databases, including Chinese Biological Medicine (CBM), China National Knowledge Infrastructure (CNKI), VIP and Wanfang. Two groups of researchers screened the studies independently, assessed the quality of the studies and extracted data. Meta-analysis was performed by using the RevMan 5.3 software. RESULTS: Five studies on psychoeducational interventions were included. Pooled analysis of these studies showed a small effect of the interventions on improving family function (WMD: -0.13, 95% CI: -0.24 to -0.01, P < 0.05). Subgroup analysis showed significant differences between the psychoeducation and control groups at 1 month postintervention (WMD: -0.12, 95% CI: -0.18 to -0.05, P < 0.05) and more than 6 months postintervention (WMD: -0.14, 95% CI: -0.24 to -0.04, P < 0.05). The psychoeducational interventions also had positive effect on improving the problem solving (WMD: -0.22, 95% CI: -0.14 to -0.03, P < 0.05) and communication (WMD: -0.23, 95% CI: -0.41 to -0.05, P < 0.05) functions of the family. There were significant differences in the group of dyad intervention (WMD: -0.14, 95% CI: -0.25 to -0.02, P < 0.05) and the group using face to face method (WMD: -0.58, 95% CI: -0.84 to -0.32, P < 0.05). CONCLUSIONS: Synthesized results demonstrated the favourable effect of psychoeducational interventions on the improvement of the family function among families after stroke, especially in terms of family problem solving and family communication. Future psychoeducational intervention research design should consider the combination of multiple intervention methods and the applicable population of intervention.

Comprehensive analysis of N6 -methyladenosine-related long non-coding RNAs for prognosis prediction in liver hepatocellular carcinoma.

BACKGROUND: Liver hepatocellular carcinoma (LIHC) is a lethal cancer. This study aimed to identify the N6 -methyladenosine (m6 A)-targeted long non-coding RNA (lncRNA) related to LIHC prognosis and to develop an m6 A-targeted lncRNA model for prognosis prediction in LIHC. METHODS: The expression matrix of mRNA and lncRNA was obtained, and differentially expressed (DE) mRNAs and lncRNAs between tumor and normal samples were identified. Univariate Cox and pathway enrichment analyses were performed on the m6 A-targeted lncRNAs and the LIHC prognosis-related m6 A-targeted lncRNAs. Prognostic analysis, immune infiltration, and gene DE analyses were performed on LIHC subgroups, which were obtained from unsupervised clustering analysis. Additionally, a multi-factor Cox analysis was used to construct a prognostic risk model based on the lncRNAs from the LASSO Cox model. Univariate and multivariate Cox analyses were used to assess prognostic independence. RESULTS: A total of 5031 significant DEmRNAs and 292 significant DElncRNAs were screened, and 72 LIHC-specific m6 A-targeted binding lncRNAs were screened. Moreover, a total of 29 LIHC prognosis-related m6 A-targeted lncRNAs were obtained and enriched in cytoskeletal, spliceosome, and cell cycle pathways. An 11-m6 A-lncRNA prognostic model was constructed and verified; the top 10 lncRNAs included LINC00152, RP6-65G23.3, RP11-620J15.3, RP11-290F5.1, RP11-147L13.13, RP11-923I11.6, AC092171.4, KB-1460A1.5, LINC00339, and RP11-119D9.1. Additionally, the two LIHC subgroups, Cluster 1 and Cluster 2, showed significant differences in the immune microenvironment, m6 A enzyme genes, and prognosis of LIHC. CONCLUSION: The m6 A-lncRNA prognostic model accurately and effectively predicted the prognostic survival of LIHC. Immune cells, immune checkpoints (ICs), and m6 A enzyme genes could act as novel therapeutic targets for LIHC.

Organic loading on biochemical fractions degradation pattern during food waste bioevaporation.

More food waste (FW) is desired to be treated in a certain processing period, while the degradation pattern of biochemical fractions during FW bioevaporation was significantly influenced by the organic loading (OL). Lower OL facilitated the lipids degradation, while higher OL favored the protein degradation. It was the more porous structure and abundant oxygen accelerated the lipids degradation, and the rapid proliferation of aerobic microorganisms compensated for the low protein degradation in lower OL. Detailly, 76.8% of the lipids was degraded in the trial with OL of 1.04 kg VSFW/kg TSBS (Trial A), but in the trial with OL of 3.16 kg VSFW/kg TSBS (Trial C) it was only 0.5%. For protein, the degradation was different that 17.5% of the protein was degraded in Trial A, whereas 69.1% was degraded in Trial C. Lipids degradation contributed 63.0% to the metabolic heat in Trial A, but its contribution in Trial C was only 0.5%. For protein, it contributed 4.1% to the metabolic heat in Trial A, but in Trial C it accounted for 53.6%. In addition, the degradation of carbohydrates (71.6-80.8%) and their contribution to metabolic heat (32.8-45.9%) were comparable in all trials, thus OL had little effect on carbohydrates degradation. Results from this study could provide important guideline for FW practical disposal during their biological treatment.

LRP1B or TP53 mutations are associated with higher tumor mutational burden and worse survival in hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is one of the most leading causes of cancer-related mortality worldwide. Immune checkpoint inhibitors (ICIs) have been proved to be beneficial for advanced HCC. Tumor mutational burden (TMB) is an important predictor for efficacy of ICIs. However, the genetic landscape of Chinese HCC patients and the association between TMB and frequently mutated genes of HCC remain unclear. Methods: Whole-exome sequencing data of 369 liver tumors from the Cancer Genome Altas (TCGA) and next generation sequencing (NGS) data of 657 liver tumors from Chinese clinical dataset were included. Results: TP53 (61.8%) was the most frequently mutated gene in the Chinese cohort, followed by CTNNB1 (17.2%), RB1 (13.7%), and LRP1B (12.3%). The PI3K-Akt signaling (11.2%), the Rap1 signaling (8.1%), and Ras signaling (7.7%), were significantly mapped. LRP1B mutations were significantly associated with higher TMB in both TCGA cohort (P = 0.0003) and Chinese cohort (P = 0.0005). And TP53 mutations were also associated with higher TMB in the TCGA and Chinese cohort (P = 0.0005 and 0.0010, respectively). Prognosis analysis performed in TCGA cohort revealed LRP1B mutations were significantly associated with shorter overall survival (OS, median, 20.9 vs 61.7 months; HR, 2.22; P = 0.0012). TP53 mutation was an independent risk factor affecting both OS (HR 1.58, P = 0.0109) and PFS (HR 1.59, P = 0.0027). Conclusions: The results suggest that LRP1B or TP53 mutations are associated with higher TMB and a poor prognostic factor in HCC.

Prognostic value of resection margin length after surgical resection for intrahepatic cholangiocarcinoma.

BACKGROUND: The definition and prognostic value of a wide resection margin remains controversial. The aim of this study was to assess the relevance of resection margin length for survival following intrahepatic cholangiocarcinoma (ICC) resection. METHODS: Patients scheduled for curative resection for ICC between 2015 and 2018 were identified from an institutional database. Demographic data, pathological margin length, and oncologic outcomes were collected and analyzed. RESULTS: This study included 126 patients, of whom 78% underwent anatomical hepatectomy. The resection margin was <0.5, <1.0, and <1.5 cm in 73 (60%), 92 (73%), and 109 (87%) patients, respectively. A resection margin ≥1.0 cm was associated with favorable overall survival (OS) (HR: 0.403; 95% CI: 0.191-0.854; P = 0.018) and recurrence-free survival (RFS) (HR: 0.436; 95% CI: 0.232-0.817; P = 0.010). In the anatomical hepatectomy group, a resection margin ≥1.0 cm was an independent predictor of superior OS (HR: 0.451; 95% CI: 0.208-0.977; P = 0.043) and RFS (HR: 0.470; 95% CI: 0.242-0.914; P = 0.026). CONCLUSIONS: A resection margin ≥1.0 cm was associated with significantly improved survival in ICC. Therefore, a clear margin of at least 1.0 cm should be achieved during ICC resection.

Comprehensive molecular profiling of intrahepatic cholangiocarcinoma in the Chinese population and therapeutic experience.

BACKGROUND: The genomic alterations of intrahepatic cholangiocarcinoma (ICC) in the Chinese population have not been fully revealed. Molecular profiling may provide a reference for clinical management, especially targeted therapy. METHODS: A retrospective study was conducted in 122 ICC patients. All patients' samples underwent next-generation sequencing (NGS), which analyzed 417 genes. The genetic characteristics, clinical management and therapeutic responses were analyzed. RESULTS: The most commonly mutated genes were TP53 (34%), KRAS (25%) and ARID1A (17%). Targeted agents were used referring to molecular profiling, in combination with chemotherapy. Twenty-two patients with wild-type KRAS/NRAS/BRAF were treated with cetuximab. The disease control and response rates were 78% and 47%, respectively, which were higher than those achieved with chemotherapy alone (72% and 11%, P = 0.16). Fifty-four patients underwent anti-VEGF treatment with bevacizumab. The disease control and response rates were 85% and 60%, respectively. Better therapeutic efficiency (P = 0.001) and longer progression-free survival (PFS) were observed in the bevacizumab-treated group compared to chemotherapy alone group (15.4 and 6.7 months, respectively; P = 0.04). The PFS of ten patients who underwent hepatectomy after combined treatment with chemotherapy and bevacizumab was longer than that of 139 patients who underwent surgical treatment (28.9 vs 18.0 months, P = 0.03). Two patients (1.6%) had signatures of microsatellite instability (MSI-H), and both benefited from immunotherapy. CONCLUSIONS: This study provides an overview of genetic alterations in Chinese ICC patients and indicates the potential clinical implications for NGS-based personalized therapies.

Measurement properties of family resilience assessment questionnaires: a systematic review.

BACKGROUND: There have been numerous measurement questionnaires to estimate the level of family resilience. However, we lack published evidence regarding the most appropriate family resilience questionnaire in different adversity domains. OBJECTIVE: This study critically assesses and contrasts the measurement properties of questionnaires measuring family resilience in two domains: health care domain and social domain. METHODS: Ten electronic databases were searched for studies concerning the establishment, adaptation or evaluation of the measurement properties of a family resilience assessment questionnaire. The methodological quality of included studies was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. On the basis of methodological quality and scoring criteria for the quality of questionnaires, the overall evidence of each questionnaire was rated. RESULTS: A total of 4084 initial studies were obtained, 23 of which met our inclusion criteria assessing 12 different questionnaires. The structural validity (23 studies) and internal consistency (22 studies) were the most frequently used measurement properties. Only two studies tested responsiveness, and the measurement error was not examined in any studies. The Family Resilience Assessment Scale (FRAS) and Italian version of the Walsh Family Resilience Questionnaire (Walsh-IT) showed positive evidence in health care domain. The FRAS performed well in social domain with specific adversity, and the Family Resilience Questionnaire (FRQ) received a good score in social domain without specific adversity. CONCLUSION: For health care domain, we recommend the FRAS and Walsh-IT. For social domain with specific adversity, we recommend the FRAS questionnaire. For social domain without specific adversity, the FRQ is recommended.

Proximity Environmental Feature Based Tree Health Assessment Scheme Using Internet of Things and Machine Learning Algorithm.

Improperly grown trees may cause huge hazards to the environment and to humans, through e.g., climate change, soil erosion, etc. A proximity environmental feature-based tree health assessment (PTA) scheme is proposed to prevent these hazards by providing guidance for early warning methods of potential poor tree health. In PTA development, tree health is defined and evaluated based on proximity environmental features (PEFs). The PEF takes into consideration the seven surrounding ambient features that strongly impact tree health. The PEFs were measured by the deployed smart sensors surrounding trees. A database composed of tree health and relative PEFs was established for further analysis. An adaptive data identifying (ADI) algorithm is applied to exclude the influence of interference factors in the database. Finally, the radial basis function (RBF) neural network (NN), a machine leaning algorithm, has been identified as the appropriate tool with which to correlate tree health and PEFs to establish the PTA algorithm. One of the salient features of PTA is that the algorithm can evaluate, and thus monitor, tree health remotely and automatically from smart sensor data by taking advantage of the well-established internet of things (IoT) network and machine learning algorithm.

Surgical treatment of ovarian cancer liver metastasis.

In addition to hepatocellular carcinoma, metastatic liver cancer (MLC) is another focus of hepatic surgeon. Good outcome of patients with liver metastasis (LM) from colorectal cancer or neuroendocrine tumor have been achieved. Ovarian cancer liver metastasis (OCLM) has its unique oncological characteristics and a variety of metastasis patterns, which brings a challenge to hepatic surgeon. Hepatic surgeons hold different views and techniques from gynecologists, which makes differences in the evaluation and treatment of the disease. We reviewed recent studies and, in combination with our own clinical experience, attempted to introduce the progress of surgical treatment of liver metastases from OC. In our experience, both preoperative imaging and surgical procedures are based on the assurance of R0 resection. R0 cytoreductive surgery (CRS) is the most favorable determinant for the prognosis of OC patients, and R0 liver resection (LR) is a component of R0 CRS. Gynecologists and hepatic surgeons should do their own preoperative and intraoperative evaluation for the extrahepatic and intrahepatic metastasis respectively. During the operation, regardless of the miliary nodules dissemination between the right hemidiaphragm and liver capsule, liver parenchymal infiltration (LPI) or liver parenchymal metastasis (LPM), 1-2 cm resection margin should be emphasized. For patients with liver portal lymph node metastasis (LPLNM), hepatic portal skeletonization should be performed, rather than portal lymph node dissection. The operation should be as radical as possible to ensure the patients to achieve good prognosis.

Antiestrogenic Activity of the Xi-Huang Formula for Breast Cancer by Targeting the Estrogen Receptor α.

BACKGROUND/AIMS: The Xi-Huang (XH) formula has been used for breast cancer treatment in traditional Chinese medicine (TCM) since 1740. In this study, we show that, XH extract could suppress the growth of breast cancer cells in vitro and in vivo, and that it preferentially inhibits cell growth of estrogen receptor positive (ER+) breast cancer cells. Presently, little is known about the potential mechanism of XH and our studies aim to elucidate its mechanism in breast cancer treatment. METHODS: Network-based systems biology and molecular docking analyses were performed to predict explicit targets of XH and active ingredients in XH. The effects of XH on cell viability, cell cycle, apoptosis in different breast cancer cell lines were analyzed in vitro. A model of transplanted tumors on nude mice was used to study the anticancer effect in vivo. Various techniques, including western blotting, reverse transcription-polymerase chain reaction (RT-PCR), immunofluorescence, co-immunoprecipitation and immunohistochemical were utilized to assess the expression of targets of XH in vitro and in vivo. RNA sequencing (RNA-seq) was performed to study the gene targets of XH. Furthermore, we analyzed of protein-ligand binding reactions by isothermal titration calorimetry (ITC). RESULTS: Using network-based systems biology and molecular docking analyses, we predicted that the major targets of XH were ERα and HSP90. Moreover, we found that, XH mediated its anti-cancer effects by promoting the disassociation of ERα and HSP90, resulting in the degradation of ERα and blockade of transport of ERα to the nucleus. XH also caused the dissociation of ERα and other oncoproteins via binding to HSP90. Some of the active ingredients in XH share a common cyclopentane hydrogen skeleton and were predicted to target ERα based on the structural similarity. CONCLUSIONS: XH, which has been used since 1740, has antiestrogenic effects in breast cancer via the targeting of ERα.

Molecular targets of Chinese herbs: a clinical study of metastatic colorectal cancer based on network pharmacology.

Increasing evidence has shown that Chinese herbal medicine (CHM) has promising therapeutic effects in colorectal cancer (CRC); however, the active ingredients and potential targets remain unclear. In this study, we aimed to investigate the relative molecular targets of the Chinese herbs that have been found effective in treating metastatic CRC (mCRC) based on clinical data and network pharmacology. In multivariate analysis CHM resulted an independent prognostic factor. The hazard ratio was 0.103 (95% confidence interval = 0.064-0.164; P < 0.001). Compared with the non-CHM group, the median survival time of the CHM group was also improved (40 versus 12 months; P < 0.001). Eighteen out of 295 herbs showed significant correlation with survival results (P < 0.05). Bioinformatics analysis indicated that the 18 herbs realize anti-CRC activity mainly through suppressing the proliferative activity of ERBB2, peroxisome proliferator-activated receptor gamma, and retinoid X receptor, suppressing angiogenesis via inhibition of VEGFR and VEGFA expression, inhibiting the phosphatidylinositol-3-kinase/AKT1 signaling pathway directly through SRC and AKT1, and reducing tumor necrosis factor-induced inflammation.

Validation of Sendai and Fukuoka consensus guidelines in predicting malignancy in patients with preoperatively diagnosed mucinous pancreatic cystic neoplasms.

BACKGROUND AND OBJECTIVES: The Sendai consensus guidelines (SCG) and Fukuoka consensus guidelines (FCG) have been examined for their roles in predicting advanced neoplasia (AN) in pancreatic cystic neoplasm (PCN) patients with mixed results. We aim to evaluate the utilities of both guidelines in a Chinese cohort with preoperatively diagnosed mucinous PCNs. METHODS: One hundred ninety-seven patients who underwent resections from 2008 to 2015 in Zhong Shan Hospital, Fudan University for suspected PCNs were retrospectively reviewed. Receiver operating characteristic (ROC) curves were calculated and compared to measure diagnostic value. RESULTS: Fifty-five patients were diagnosed with AN pathologically. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the SCG high-risk (SCGHR ) criteria were 87.3%, 28.2%, 32.0%, 85.1%, and 44.7%, respectively, and for the FCG high-risk (FCGHR ) criteria, they were 40.0%, 95.8%, 78.6%, 80.5%, and 80.2%, respectively. ROC curve comparison analyses showed that the FCGHR were superior to the SCGHR (P = 0.02). The performance of the FCGHR was enhanced with CA19-9 incorporated (P = 0.004). CONCLUSIONS: The FCG were superior to the SCG in this retrospective analysis, which could be further improved by the incorporation of CA19-9. However, the practical safety remains uncertain because of missed invasive carcinoma cases.
