The role of age and body mass index on cancer occurrence in a hypertensive population:a retrospective cohort study / 复旦学报（医学版）

Objective To analyze the combined effect of body mass index(BMI)and age with cancer occurrence among a hypertensive population in Minhang District,Shanghai.Methods Participants of this study were 212 394 hypertensive patients without cancer in Minhang District,Shanghai,registered in the electronic health information system from 2007 to 2015.Age and BMI were included as smoothing functions in the generalized additive Cox proportional risk model.The bivariate response model was constructed to visualize results using surface plots and to comprehensively analyze the association of BMI and age with the risk of cancer occurrence.Results A total of 22 141 participants developed cancer by Dec 31,2018.The association between age and the risk of cancer incidence showed an overall linear trend while the association between BMI and the risk of cancer incidence showed an overall"U"shape.BMI at about 26 kg/m2 showed the lowest risk of cancer incidence.The risk of cancer occurrence increased with increasing age in people with different BMIs.The associations between BMI and the risk of cancer incidence were different at different age groups:there was no significant association between BMI and the risk of cancer incidence in the young people(20-44 years).While in the middle-aged and older people aged over 45 years,BMI was associated with the risk of cancer incidence in a"U"shape.The lowest risk of cancer incidence was around the BMI of 26 kg/m2.Conclusion BMI among the population with hypertension should be controlled in a reasonable range,especially in the middle-aged and older population,to prevent cancer occurrence.

Compound Dihuang Granule Changes Gut Microbiota of MPTP-Induced Parkinson's Disease Mice via Inhibiting TLR4/NF-κB Signaling.

Intestinal microbiota was connected to Parkinson's Disease (PD) pathology. The ancient Chinese medication for PD is Compound Dihuang Granule (CDG), and we found a neuroprotective function in treating the constipation of PD patients. Nevertheless, the mechanism of action still needs to be clarified. We predicted the probable targets of CDG against PD through Traditional Chinese medicine (TCM) network pharmacology and verified the analysis through animal experiments in vivo. The protein-protein interaction (PPI) network analysis screened PD-related genes, including Toll-like receptor 4(TLR4), TANK-binding kinase 1(TBK1), Nuclear Factor- Kappa B (NF-κB), and Tumor necrosis factor (TNF). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses proved that the NF-κB and toll-like receptor signaling pathways serve a key function in CDG therapy of PD. Molecular docking analysis demonstrated that CDG strongly connected to TLR4/NF-κB. Experiments findings indicated that CDG improved the damage of dopaminergic neurons and gut microbial dysbiosis, ameliorated motor impairments, and suppressed the PD-associated inflammation and oxidative stress in mice induced by 1-methyl-4-phenyl-1,2,3,6-tetrahy dropyridine (MPTP). CDG suppressed the inflammatory proteins in the colon and protected the intestinal barrier. Overall, CDG improved gut microbial in PD by blocking the pathway of TLR4/NF-κB.

Unconventional surgery for thoracic esophageal rupture with empyema and mediastinitis: a case report and literature review.

Treatment of esophageal perforation or rupture is complicated and controversial, especially in advanced cases. In fact, it is generally accepted that this disease must be treated individually according to the location, causes and clinical features of rupture or perforation. A very rare case was admitted to our department, who was injured 5 days ago by high-pressure gas of a running air compressor and resulted in a long-term longitudinal rupture of the thoracic esophagus. Although the patient suffered from empyema and mediastinitis at the same time, and his condition was very serious, the debridement and desquamation of empyema were still implemented, followed by left thoracic esophagectomy and left neck approach esophagogastrostomy in the same period successfully. The patient got a good result finally.

Specific Mutations in APC, with Prognostic Implications in Metastatic Colorectal Cancer / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#Loss-of-function mutations in the adenomatous polyposis coli (APC) gene are common in metastatic colorectal cancer (mCRC). However, the characteristic of APC specific mutations in mCRC is poorly understood. Here, we explored the clinical and molecular characteristics of N-terminal and C-terminal side APC mutations in Chinese patients with mCRC. @*Materials and Methods@#Hybrid capture-based next-generation sequencing was performed on tumor tissues from 275 mCRC pati-ents to detect mutations in 639 tumor-associated genes. The prognostic value and gene-pathway difference between APC specific mutations in mCRC patients were analyzed. @*Results@#APC mutations were highly clustered, accounting for 73% of all mCRC patients, and most of them were truncating mutations. The tumor mutation burden of the N-terminal side APC mutations group (n=76) was significantly lower than that of the C-terminal side group (n=123) (p < 0.001), further confirmed by the public database. Survival analysis showed that mCRC patients with N-terminus side APC mutations had longer overall survival than C-terminus side. Tumor gene pathway analysis showed that gene mutations in the RTK/RAS, Wnt and transforming growth factor β signaling pathways of the C-terminal group were significantly higher than those of the N-terminal group (p < 0.05). Additionally, KRAS, AMER1, TGFBR2, and ARID1A driver mutations were more common in patients with C-terminal side APC mutations. @*Conclusion@#APC specific mutations have potential function as mCRC prognostic biomarkers. There are obvious differences in the gene mutation patterns between the C-terminus and N-terminus APC mutations group, which may have certain guiding significance for the subsequent precise treatment of mCRC.

Astragaloside IV inhibits Ang H-induced cell proliferation and collagen expression in cardiac fibroblasts by activating short-chain acyl-CoA dehydrogenase / 中国药理学通报

Aim To explore the effect of astragaloside IV (AS-IV) on cell proliferation and collagen expression in cardiac fibroblasts (CFs) of rats induced with angiotensin II (Ang II) and its mechanism. Methods CFs were pretreated with short-chain acyl-CoA dehydrogenase (SCAD) siRNA1186 for 12 h and then co-treated with Ang TJ and AS-IV for 36 h. The expressions of SCAD, α-SMA, collagen I and collagen III in CFs were detected by Western blot. mRNA expression levels of SCAD, a-SMA, collagen I and collagen III in CFs were detected by quantitative real-time PCR. The SCAD enzymatic activity, the content of ATP, hydroxyproline and free fatty acid were measured by detection kits. Results The expression of α-SMA, collagen I and collagen III were up-regulated (all P < 0. 01) in CFs induced by Ang II compared with the control cells, and the expression and enzymatic activity of SCAD significantly decreased (P < 0. 01, P< 0. 05). The content of ATP decreased (P < 0.01), and the content of hydroxyproline and free fatty acids increased (all P < 0.01). Compared with Ang II group, SCAD expression and enzymatic activity, and ATP content were significantly increased (all P < 0.01) in Ang II + AS-TV group, but the content of hydroxyproline and free fatty acids, and the expression of α-SMA, collagen I and collagen III significantly decreased (all P < 0.01). However, compared with the Ang II + NC group, there was no significant difference in all indices in the Ang II + SiRNA1186 + AS-TV group. The protective effect of AS-TV on Ang II -induced cell proliferation and collagen expression in CFs was eliminated by the interference of SCAD SiRNA1186. Conclusions AS-IV may inhibit Ang II-induced cell proliferation and collagen expression in CFs by activating SCAD.

Case report: Quadruple primary malignant neoplasms including esophageal, ureteral, and lung in an elderly male.

Multiple primary malignant neoplasms (MPMNs) are defined as multiple tumors with different pathogenic origins. MPMNs are rare, but the morbidity rate is on the rise. With the development of anti-tumor treatments, such as targeted therapy and immunotherapy, the overall survival of cancer patients has been significantly prolonged, leading to an increased number of patients with MPMNs. A crucial aspect of MPMNs management is deciding how to schedule further treatments according to individual tumor risk. This process involves a multidisciplinary physician team to ensure favorable outcomes. Herein we report a 60-year-old male who developed four different malignancies, including esophageal squamous cell carcinoma, upper urinary tract urothelial carcinoma, mediastinal small cell lung cancer, and left lung squamous cell carcinoma over 20 years and received appropriate treatment of each cancer with long survival.

Protective effect of rutin against diabetes-associated cognitive decline in rats.

Diabetes is a well-known risk factor for cognitive deficit. Rutin (RUT) possesses diverse pharmacological activities and is widely used in diabetic complication. The aim of this study is to assess the improvement of RUT on diabetes-associated cognitive decline (DACD). In our study, Morris water maze was examined to estimate cognitive function. In hippocampus tissue, spectrophotometer was performed to evaluate super oxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH), malondialdehyde (MDA), acetyl cholinesterase (AChE) and choline acetyl transferase (ChAT) levels. Quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA) were utilized to analyze Tumor necrosis factor-a (TNF-a) and interleukin-1ß (IL-1ß) contents. Western blot was used to detect the protein expressions of brain derived neurotrophic factor (BDNF), glial fibrillary acidic protein (GFAP), nuclear factor erythroid-2-related factor-2 (Nrf-2) and heme oxygenase-1 (HO-1). Our data revealed that RUT markedly improved learning and memory capacities in Morris water maze test. In hippocampus, RUT markedly inhibited AChE, GFAP MDA, TNF-a and IL-1ß levels and augmented ChAT and BDNF, SOD, CAT, GSH, Nrf-2 and HO-1 levels. In conclusion, RUT may be involved in protection efficacy against STZ-induced cognitive deficits via improvement of oxidative stress, inflammatory response and Nrf-2/HO-1 pathway.

Paeoniflorin ameliorates cognitive impairment in Parkinson's disease via JNK/p53 signaling.

Paeoniflorin (PF) has numerous benefits, including anti-inflammatory and anti-apoptosis effects. However, it is not clear if it has neuroprotective effects against cognitive impairment (CI) in Parkinson's disease (PD). Through network pharmacology, we identified probable targets as well as signal pathways through which PF might affect CI in PD. Then, we experimentally validated our findings. The core genes of the protein-protein interactions (PPI) network include MAPK8 (JNK), TP53, CASP3 (caspase-3), postsynaptic density protein-95 (PSD-95) and synaptophysin (SYN). Pathway enrichment analysis revealed that genes involved in apoptosis and mitogen-activated protein kinase (MAPK) signaling were significantly enriched. Because JNK is a key mediator of p53-induced apoptosis, we wondered if JNK/p53 pathway influences the effects of PF against apoptosis in mouse model of PD. Molecular docking analysis showed that PF had good affinity for JNK/p53. The results of the experiments indicated that PF ameliorated behavioral impairments and upregulated the expression of the dopamine (DA) neurons, suppressed cell apoptosis in substantia nigra pars compacta (SNpc) of PD. Additionally, PF improved 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced neuronal injury by inhibiting apoptosis in hippocampal neurons of the CA1 and CA3, and upregulating PSD-95 as well as SYN protein levels. Similar protective effects were observed upon JNK/p53 pathway inhibition using SP600125. Overall, PF improved CI in PD by inhibiting JNK/p53 pathway.

Riboflavin inhibits heart failure in mice by activating SCAD / 中国药理学通报

Aim To explore the effeet of riboflavin on the establishment of pressure overload-induced heart failure model in mice by thoracic aortie constrietion (TAC ) and its preventive mechanism.Methods Eight-week-old SPF C57BL/6J mice were seleeted and divided into four groups; Sham group.Sham + ribofla¬vin group, TAC group and TAC + riboflavin group.A mouse heart failure model was constructed in the TAC group.The miee in the TAC + riboflavin group were given riboflavin by gavage one week before and eight weeks after the operation.The cardiac ultrasound inde¬xes, the changes of cardiac morphology and mitochon¬drial function indexes, the expression of apoptosis pro¬teins, ATP content, SCAD mRNA and protein expres¬sion, enzyme activity and flavin adenine dinucleotide (FAD) content in myocardial tissues were detected.Hie free fatty acid content in serum and myocardial tis¬sues were also detected.Results Compared with the sham group, the cardiac function indexes of the mice in the TAC group decreased, anrl typical heart failure occurred.Moreover, the expression of SCAD, enzyme activity, ATP and FAD content in the myocardium sig-nificantly decreased, and the free fatty acid content in myocardium and serum significantly increased.Com¬pared with the TAC group, after riboflavin treatment, the cardiac function of mice in TAC + Riboflavin group was significantly improved.In addition, ATP content, SCAD expression, enzyme activity and FAD content in myocardium all significantly increased, and free fatty acid content in myocardium and serum markedly de¬creased.Conclusions Riboflavin may improve myo-cardial energy metabolism by increasing FAD content and activating SCAD, thereby inhibiting pressure over¬load-induced heart failure in mice.

Misdiagnosis and Delay of Diagnosis in Hemorrhagic Meningioma: A Case Series and Review of the Literature.

OBJECTIVE: To evaluate the clinicoradiologic characteristics of hemorrhagic meningiomas (HMs) that are missed or misdiagnosed on radiologic imaging studies. METHODS: Clinical and radiologic data from 6 patients with HM who were initially misdiagnosed were collected and recorded respectively. In addition, we performed a literature review for misdiagnosed HM and summarized the results. RESULTS: Five of the 6 patients with misdiagnosed HM were female, and 1 was male. Both computed tomography (CT) and magnetic resonance imaging were performed in 4 patients, and CT alone was performed in 2. On CT, the HM was heterogeneously hyperdense in 5 patients and isodense in 1 patient. In all 4 patients who underwent magnetic resonance imaging, the HM was mixed iso- and hypointense on T1-weighted imaging and heterogeneously hyperintense on T2-weighted imaging. Marked heterogeneous contrast enhancement was observed in 2 patients, strong rim enhancement in 1, and peripheral enhancement in 1. The dural tail sign was seen in only 1 patient. The initial radiologic misdiagnoses were subdural hematoma (n = 1), malignant glioma (n = 1), ruptured arterial aneurysm (n = 1), metastasis (n = 2), and uncertain (n = 1). In the literature review, 22 cases of HM diagnostic error were collected. The main misdiagnoses were subdural hematoma (27.3%), traumatic hematoma (13.6%), vascular anomaly (13.6%), malignant glioma (4.5%), and metastasis (4.5%). CONCLUSIONS: Our study showed that in patients with HM with inadequate imaging evaluation, a small tumor associated with massive hematoma and atypical imaging features was more likely to be misdiagnosed.

ITGBL1 promotes gastric cancer cell proliferation and invasion via Akt signal pathway.

Integrin beta- like 1 (ITGBL1), an extracellular matrix protein, plays an oncogenic role in diverse forms of cancers. To this end, we examined the importance of ITGBL1 in gastric cancer (GC). The upregulated expression of ITGBL1 in GC was associated with a poor prognosis. Moreover, upregulation of ITGBL1 enhanced cell mobility while silencing it exerted an opposite effect. Up-regulation of ITGBL1 significantly promoted phosphorylation of Akt, decreased the ratio of phosphorylated Akt in AGS/ITGBL1-shRNA and N87/ITGBL1-shRNA cells, enhanced cell mobility and proliferation. Silencing ITGBL1 had an opposite effect on Akt phosphorylation, cell mobility, and proliferation. These findings show that ITGBL1 regulates mobility and proliferation of GC likely through activation of Akt signaling.

Herpes simplex virus type I-infected disorders alter the balance between Treg and Th17 cells in recurrent herpes labialis patients.

Recurrent herpes labialis (RHL) is a common skin disease that is often caused by herpes simplex virus type I (HSV-1), but its immunology and pathogenesis remain unclear. The balance of Th17/Treg cells is crucial for maintaining immune homeostasis. This study aimed to investigate whether the balance of Th17/Treg cells and related cytokines may be a determinant occurrence in patients with RHL. This is a clinical experimental research based on clinical observation and analysis. We collected RHL patients from the outpatient clinic of the Department of Dermatology of Zhejiang Chinese Medical University (Hangzhou, China) in 2017, conducted questionnaire survey and signed informed consent. Peripheral blood was collected from 30 patients with RHL and 30 healthy volunteers. Flow cytometry was used to detect the percentages of Treg cells and Th17 cells. Protein microarrays coated with 20 cytokines related to T-cell subsets were performed. Enzyme-linked immunosorbent assay (ELISA) assay was conducted to further verify the expression levels of the cytokines that were screened by protein microarrays. Percentages of Th17/Treg cells in peripheral blood of RHL patients were significantly increased compared to those in healthy volunteers. The fold changes of GM-CSF, IL-4, TGF-ß, IL-12, IL-10, IL-17F, and TNF-α were significantly increased compared with healthy volunteers. In addition, the expression of IL-4, IL-10, and TGF-ß in the serum of RHL patients increased significantly. Our results indicated an imbalance of Th17/Treg cells in RHL, and this imbalance is probably an important factor in the occurrence, development, and recovery of RHL.

OBJECTIVE: To investigate the clinical features,diagnosis and treatment of thyroid tumor complicated with tumor thrombus in internal jugular vein. METHODS: Case reports of thyroid tumor complicated with tumor thrombus in internal jugular vein published in domestic journals since January 2000 were retrieved. The clinical features and treatment procedures were analyzed combining with the data of 2 patients admitted to the Department of Vascular and Thyroid Surgery of Guizhou Provincial People's Hospital. RESULTS: A total of 10 reports were retrieved,including 23 patients.Of the 25 patients,14 were males and 11 were females,aged 44—84(62.9±9.8)years. The largest diameter of thyroid tumor was 2.8—8.0 cm.The length of tumor thrombus ranged from 1 cm to 30 cm. Among the 19 cases,14 were derived from intravascular spreading tumor thrombus,and 5 were from direct invasive tumor thrombus.There were 4 cases of papillary carcinoma,6 cases of follicular carcinoma,5 cases of poorly differentiated carcinoma,8 cases of undifferentiated carcinoma,1 case of myogenic sarcoma and 1 case of sclerosing epithelioid fibrosarcoma. Of the 13 cases,9 underwent internal jugular vein resection and 4 underwent thrombectomy. CONCLUSION: Thyroid tumors complicated with tumor thrombus in internal jugular vein are mostly tumors with strong vascular invasion ability.The long-term prognosis of the patients is very poor. Surgical treatment should be actively taken to remove the tumor thrombus and improve the prognosis of the patients.

[Effect of allicin on proliferation and apoptosis of KG-1 cells and its molecular mechanism].

Allicin is one of the main bioactive substances in garlic, with antibacterial, hypolipidemic and other pharmacological effects. In this study, apoptosis-related indicators were detected to explore the molecular mechanism of allicin on KG-1 cell proliferation inhibition. The apoptosis rate of KG-1 cells induced by allicin was detected by flow cytometry. The effect of allicin on the expressions of Bax, Bcl-2, survivin and ERK mRNA in KG-1 cells was detected by RT-qPCR. Western blot was used to detect the expressions of caspase 3, cleaved caspase 3, ERK1/2, p-ERK1/2 and survivin protein in KG-1 cells. According to the findings, compared with the control group, allicin could significantly inhibit the proliferation activity of KG-1 cells in a concentration-dependent and time-dependent manner. Flow cytometry showed that allicin could induce the apoptosis of KG-1 cells, which was mainly late apoptosis. The results of RT-qPCR showed that the expressions of Bax mRNA, Bcl-2, survivin and ERK mRNA in KG-1 cells increased after treatment with allicin. The results of Western-blot showed that after KG-1 cells were treated with allicin, the expressions of caspase 3 and its active form cleaved caspase 3 increased, the expressions of survivin, ERK1/2 and its active form p-ERK1/2 were decreased, of which p-ERK1/2 was down-regulated in a dose-dependent manner. The above results suggest that allicin inhibited the proliferation of KG-1 cells primarily by inducing late apoptosis; the execution of apoptosis involved cleaved caspase 3; the induction of apoptosis involved the protein expression, the decrease of ERK1/2andexpression of survivin and the dose-dependent decrease of p-ERK1/2; the mRNA expression involved the increase of Bax, and the down-regulation of survivin, Bcl-2 and ERK1/2.

Expression of Imprinted Genes Kcnq1 and Cdkn1c During the Course of Differentiation from Mouse Embryonic Stem Cells into Islet-like Cells in vitro.

To study the effects of inducement on the expression of mouse embryonic stem cells SF1-G imprinted genes, Kcnq1 and Cdkn1c during the course of differentiation into islet-like cells in vitro. Mouse embryonic fibroblasts (MEFs) were isolated from pregnant mice embryos and fibroblast feeder cells were prepared by treating 3-5th generations MEFs with Mitomycin C. Moreover, mouse embryonic stem cells were induced to differentiate into islet-like cells directly. RT-PCR and Immunofluorescence staining were used to test the expression of islet cell-specific markers. Cells were collected at various stages throughout the differentiation process and the imprinted genes Kcnq1 and Cdkn1c were tested by reverse transcription-polymerase chain reaction fragment length polymorphism (RT-PCR/RFLP). In the present study, we found that cells appear islet cell-specific gene expression. Furthermore, immunofluorescence shows us that the islet cell-specific hormone protein can be measured at stage, which confirms that the embryonic stem cells can be successfully induced into islet-like cells in vitro. RT-PCR/RFLP analysis showsthat imprinted genes Kcnq1 and Cdkn1c are biallelic expression in the differentiated cells, suggestive of loss of imprinting (LOI), while these genes demonstrate maternal monoallelic expression in the undifferentiated cells' continued subculture; this marks the maintenance of imprinting (MOI). Our data indicate that mouse embryonic stem cells are induced into islet-like cells in vitro. The gene imprinting status of Kcnq1 and Cdkn1c may be changed in differentiated cells during the induction in vitro.
