Abstract
Objective: Quantified MRCP imaging data was used as a reference for design and preparation of a modified percutaneous transhepatic cholangio drainage (PTCD) tube. Methods: 3.0 T upper abdominal MR and MRCP imaging data of 2 300 patients treated from July 2015 to July 2020 at the Department of Radiology of the Affiliated Cancer Hospital of Zhengzhou University were screened and a total of 381 patients diagnosed with biliary duct structures were identified. Causative etiologies among these patients included pancreatic adenocarcinoma (pancreatic head), cholangiocarcinoma, ampullary carcinoma, as well as intrahepatic and/or extrahepatic bile duct dilation. An improved PTCD tube was designed based on MRCP quantification of left and right hepatic and common hepatic duct length. Results: In the setting of biliary obstruction caused by malignancy, the distance of the left hepatic duct from its origin to the point of left and right hepatic duct confluence was 15.9±3.8 mm, while the distance of the right hepatic duct from its origin to the point of left and right hepatic duct confluence was 12.4±3.2 mm; the length of the bile duct from its origin to the point of left and right hepatic duct confluence was 34.0±8.1 mm. The improved PTCD tube design incorporated an altered length of the drainage orifice. Conclusion: MRCP imaging of the biliary tract is effective for measuring biliary tract length in the setting of pathological dilation. Based on our biliary tract measurements, a modified PTCD tube was designed to more effectively meet drainage requirements and manage biliary obstruction caused by Bismuth-Corlette type Ⅱ and Ⅲ malignancies.

Abstract
Objective: The status and influencing factors of reproductive health (including menstrual period and gynecological diseases) of female workers in different positions of oilfield enterprises were analyzed. Methods: From January to December 2020, a total of 979 female workers in an oil field were selected as research objects by the judgment sampling method, and the "Female Reproductive Health Survey" was used as the investigation tool to investigate the demographic characteristics, menstrual status and gynecological diseases. The influential factors were analyzed by 2-test and logistic regression analysis. Results: The prevalence of abnormal menstruation was 26.1% (256/979), dysmenorrhea 53.1% (520/979), and gynecological diseases 54.34% (532/979). The prevalence of breast disease was 23.39% (229/979), uterine disease 11.03% (108/979), cervical disease 10.32% (101/979), and HPV infection 7.97% (78/979). Age, the nature of the job and whether occupational harmful factors were clear were the influencing factors of gynecological diseases (P=0.001, 0.000, 0.007). Age, job nature, working hours and work intensity were the influencing factors of abnormal menstruation (P=0.005, 0.000, 0.000, 0.010) . Conclusion: The reproductive health status of female workers in different positions of oil field enterprises is not optimistic, and the reproductive health status of female workers in professional and technical positions needs to be improved.

Abstract
BACKGROUND At present, nucleic acid testing is the gold standard for diagnosing influenza A, however, this method is expensive, time-consuming, and unsuitable for promotion and use in grassroots hospitals. This study aimed to establish a diagnostic model that could accurately, quickly, and simply distinguish between influenza A and influenza like diseases. METHODS Patients with influenza-like symptoms were recruited between December 2019 and August 2023 at the Children's Hospital Affiliated to Shandong University and basic information, nasopharyngeal swab and blood routine test data were included. Computer algorithms including random forest, GBDT, XGBoost and logistic regression (LR) were used to create the diagnostic model, and their performance was evaluated using the validation data sets. RESULTS A total of 4188 children with influenza-like symptoms were enrolled, of which 1992 were nucleic acid test positive and 2196 were matched negative. The diagnostic models based on the random forest, GBDT, XGBoost and logistic regression algorithms had AUC values of 0.835,0.872,0.867 and 0.784, respectively. The top 5 important features were lymphocyte (LYM) count, age, serum amyloid A (SAA), white blood cells (WBC) count and platelet-to-lymphocyte ratio (PLR). GBDT model had the best performance, the sensitivity and specificity were 77.23% and 80.29%, respectively. CONCLUSIONS A computer algorithm diagnosis model of influenza A in children based on blood routine test data was established, which could identify children with influenza A more accurately in the early stage, and was easy to popularize.

Abstract
Objective: To assess the clinical value of bedaquiline in five dimensions: effectiveness, safety, economics, appropriateness, and social benefits, to provide a reference for medical and health insurance-related decisions. Methods: A total of 792 patients with multidrug-resistant tuberculosis who were hospitalized at Wuhan Pulmonary Hospital, Ganzhou Fifth People's Hospital and Jiangxi Chest Hospital between January 2018 and December 2020 were included in the study. Based on a retrospective survey of case data, and each evaluation dimension of bedaquiline was statistically analyzed by causal analysis or chi-square test, using linezolid as the reference drug. Results: In terms of effectiveness, bedaquiline significantly increased treatment success by 23.9% (95%CI:4.8%-43.0%) and shortened treatment duration by 64 days(95%CI:18-109 days). In terms of safety, the incidence of adverse reactions to bedaquiline and the discontinuation rate of adverse reactions (5.11%,4.55%) were significantly lower than those for linezolid (22.49%,15.24%), with statistically significant differences (χ2=27.50,P<0.001;χ2=14.09,P<0.001). In terms of economics, patients treated with bedaquiline had a significantly higher anti-TB drug course cost of RMB 48 209.4 Yuan(95%CI: 28 336.0-68 082.8 Yuan). In terms of appropriateness, the proportion of bedaquiline in patients' initial treatment regimens was lower than that of linezolid (16.7% vs. 86.5%) in the 2020 observation sample, with a statistically significant difference (χ2=238.96,P<0.001). In terms of social benefits, the infection control rate was significantly increased by 27.8% (95%CI:8.2%-47.5%) in patients using bedaquiline. Conclusions: Bedaquiline performed well in terms of efficacy, safety, and social benefits. However, it was less economical and the actual use rate of bedaquiline in clinical practice was lower than that of its counterpart drug, linezolid. Price reductions might be needed to increase the clinical use and performance of bedaquiline in the future.

Abstract
Genomic instability can promote inflammation and tumor development. Previous research revealed an unexpected layer of regulation of genomic instability by a cytoplasmic protein MYO10; however, the underlying mechanism remained unclear. Here, we report a protein stability-mediated mitotic regulation of MYO10 in controlling genome stability. We characterized a degron motif and phosphorylation residues in the degron that mediate β-TrCP1-dependent MYO10 degradation. The level of phosphorylated MYO10 protein transiently increases during mitosis, which is accompanied by a spatiotemporal cellular localization change first accumulating at the centrosome then at the midbody. Depletion of MYO10 or expression of MYO10 degron mutants, including those found in cancer patients, disrupts mitosis, increases genomic instability and inflammation, and promotes tumor growth; however, they also increase the sensitivity of cancer cells to Taxol. Our studies demonstrate a critical role of MYO10 in mitosis progression, through which it regulates genome stability, cancer growth, and cellular response to mitotic toxins.

Abstract
PURPOSE The role of radiation therapy in mucosa-associated lymphoid tissue (MALT) lymphoma is poorly defined. The objective of this study was to explore the factors associated with the performance of radiotherapy and to assess its prognostic impact in patients with MALT lymphoma. PATIENTS AND METHODS Patients with MALT lymphoma diagnosed between 1992 and 2017 were identified in the US Surveillance, Epidemiology, and End Results database (SEER). Factors associated with the delivery of radiotherapy were assessed by chi-square test. Overall survival (OS) and lymphoma-specific survival (LSS) were compared between patients with and without radiotherapy, using Cox proportional hazard regression models, in patients with early stage as well as those with advanced stage. RESULTS Of the 10,344 patients identified with a diagnosis of MALT lymphoma, 33.6% had received radiotherapy; this rate was 38.9% for stage I/II patients and 12.0% for stage III/IV patients, respectively. Older patients and those who already received primary surgery or chemotherapy had a significantly lower rate of receiving radiotherapy, regardless of lymphoma stage. After univariate and multivariate analysis, radiotherapy was associated with improved OS and LSS in patients with stage I/II (HR=0.71 [0.65-0.78]) and (HR=0.66 [0.59-0.74]), respectively, but not in patients with stage III/IV (HR=1.01 [0.80-1.26]) and (HR=0.93 [0.67-1.29]). The nomogram built from the significant prognostic factors associated with overall survival of stage I/II patients had a good concordance (C-index=0.749±0.002). CONCLUSION This cohort study shows that radiotherapy is significantly associated with a better prognosis in patients with early but not advanced MALT lymphoma. Prospective studies are needed to confirm the prognostic impact of radiotherapy in patients with MALT lymphoma.

Abstract
We have studied the lymphatic phenotypes of 2 mutations, known to cause abnormalities of lymphatics in humans, in mice. The Cx47 R260C mutation (variably penetrant in humans heterozygous for it and causing limb lymphedema) had an adult mouse phenotype of hyperplasia and increased lymph nodes only in homozygous condition but we did not find any anatomical phenotype in day 16.5 homozygous embryos. Mice harboring the Sos1 mutation E846K (causing Noonan's 4 in man which occasionally shows lymphatic dysplasia) had no adult heterozygous phenotype in lymphatic vessel appearance and drainage (homozygotes are early embryonic lethals) while day 16.5 heterozygous embryos also had no detectable anatomical phenotype.

Abstract
Cardiac glycosides (CGs) are bioactive compounds originally used to treat heart diseases, but recent studies have demonstrated their anticancer activity. We previously demonstrated that Antiaris toxicaria 2 (AT2) possesses anticancer activity in KRAS mutated lung cancers via impinging on the DNA damage response (DDR) pathway. Toward developing this class of molecules for cancer therapy, herein we report a multistep synthetic route utilizing k-strophanthidin as the initial building block for determination of structure-activity relationships (SARs). A systematic structural design approach was applied that included modifications of the sugar moiety, the glycoside linker, stereochemistry, and lactone ring substitutions to generate a library of O-glycosides and MeON-neoglycosides derivatives. These molecules were screened for their anticancer activities and their impact on DDR signaling in KRAS mutant lung cancer cells. These results demonstrate the ability to chemically synthesize CG derivatives and define the SARs to optimize AT2 as a cancer therapeutic.

Abstract
Abstract
Cardiac Glycosides (CGs) are used to treat congestive heart disease. Their application has since been extended to cancer treatment. While the mechanism of action is still unknown, it was previously believed that Na+/K+ ATPase might play a crucial role in cancer mitigation. However, we recently reported that cardiac glycosides could specifically enhance the anti-cancer effect of chemotherapy in KRAS mutant lung cancer by inhibiting the DNA Damage Response (DDR), and these effects were independent of the Na+/K+ ATPase. Mechanistically, we showed that cardiac glycosides induced the degradation of UHRF1, an important player in promoting DNA double strand break (DSB) repair through homologous recombination. These results suggest the promise of derivatizing cardiac glycosides into potential chemo sensitizing agents. Yet, one of the major challenges with these compounds is their cardiotoxicity. This has created a need for developing a strategy to generate less cardiotoxic drugs that are effective in inhibiting the DNA damage response to safe and effective anticancer activity. Herein we report a multi-step synthetic route utilizing k-strophanthidin as the initial building block. A systematic structural design was applied that included modification of the sugar moiety, glycoside linker, stereochemistry, and lactone ring to create a library of O-glycosides and MeON-neoglycosides. These molecules were screened for anti-cancer properties by exploring their influence on the signaling/expression of various downstream kinases in the DDR pathway. We discovered the inhibitory activity of O-glycosides to be more potent than the MeON-neoglycosides or benzylidene-lactone modified compounds. These results demonstrate the ability to chemically synthesize CG derivatives to optimize for anticancer activity with the goal of identifying less cardiotoxic CGs.

Abstract
Human 53BP1 is primarily known as a key player in regulating DNA double strand break (DSB) repair choice; however, its involvement in other biological process is less well understood. Here, we report a previously uncharacterized function of 53BP1 at heterochromatin, where it undergoes liquid-liquid phase separation (LLPS) with the heterochromatin protein HP1α in a mutually dependent manner. Deletion of 53BP1 results in a reduction in heterochromatin centers and the de-repression of heterochromatic tandem repetitive DNA. We identify domains and residues of 53BP1 required for its LLPS, which overlap with, but are distinct from, those involved in DSB repair. Further, 53BP1 mutants deficient in DSB repair, but proficient in LLPS, rescue heterochromatin de-repression and protect cells from stress-induced DNA damage and senescence. Our study suggests that in addition to DSB repair modulation, 53BP1 contributes to the maintenance of heterochromatin integrity and genome stability through LLPS.

Abstract
We have studied the lymphatic phenotypes of 2 mutations, known to cause abnormalities of lymphatics in humans, in mice. The Cx47 R260C mutation (variably penetrant in humans heterozygous for it and causing limb lymphedema) had an adult mouse phenotype of hyperplasia and increased lymph nodes only in homozygous condition but we did not find any anatomical phenotype in day 16.5 homozygous embryos. Mice harboring the Sos1 mutation E846K (causing Noonan's in man which occasionally shows lymphatic dysplasia) had no adult heterozygous phenotype in lymphatic vessel appearance and drainage (homozygotes are early embryonic lethals) while day 16.5 heterozygous embryos also had no detectable anatomical phenotype.

Abstract
Genomic instability is a hallmark of human cancer; yet the underlying mechanisms remain poorly understood. Here, we report that the cytoplasmic unconventional Myosin X (MYO10) regulates genome stability, through which it mediates inflammation in cancer. MYO10 is an unstable protein that undergoes ubiquitin-conjugating enzyme H7 (UbcH7)/β-transducin repeat containing protein 1 (β-TrCP1)–dependent degradation. MYO10 is upregulated in both human and mouse tumors and its expression level predisposes tumor progression and response to immune therapy. Overexpressing MYO10 increased genomic instability, elevated the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING)–dependent inflammatory response, and accelerated tumor growth in mice. Conversely, depletion of MYO10 ameliorated genomic instability and reduced the inflammation signaling. Further, inhibiting inflammation or disrupting Myo10 significantly suppressed the growth of both human and mouse breast tumors in mice. Our data suggest that MYO10 promotes tumor progression through inducing genomic instability, which, in turn, creates an immunogenic environment for immune checkpoint blockades.

Abstract
Aim: This work aims to develop an injectable nano-drug delivery system to overcome tumor multidrug resistance (MDR). Methods: A drug delivery nanoplatform based on PEGylated PLGA with glutathione (GSH) responsivity was constructed for dual delivery of doxorubicin and curcumin (termed DCNP), and its MDR reversal efficiency was studied in vitro and in vivo. Results: The DCNPs exhibited a rapid drug release profile under high GSH concentration and could enhance the cellular uptake and cytotoxicity of doxorubicin to MDR cancer cells. Moreover, the DCNPs showed better biocompatibility, longer blood circulation and enhanced antitumor efficiency compared with free drugs. Conclusion: The GSH-responsive nanocarrier is believed to be a promising candidate for overcoming tumor MDR.

Background
Patients receiving chemotherapy for breast cancer (BC) may develop cardiac electrophysiological abnormalities. The aim of this study is to examined possible alterations in cardiac electrophysiological parameters detected by three-dimensional vectorcardiograms (3D-VCGs) in BC patients who received chemotherapy.
Methods
This was a prospective single-center cohort study conducted. Patients with BC referred for chemotherapy from May 1, 2019, to October 1, 2019 were invited to participate in the study. 3D-VCG and echocardiography were recorded at rest four times (baseline, after the first cycle, after third cycles and at the end of the regimen, respectively).
Results
A total of 63 patients were included. Compared with baseline, decreases in 3-dimensional maximum T vector magnitude (TVM) (0.29 ± 0.10 vs. 0.25 ± 0.10mV; p < 0.05) and 3-dimensional T/QRS ratio (0.26 ± 0.11 vs. 0.21 ± 0.11; p < 0.05) were observed by the end of chemotherapy regimen, while echocardiographic parameters showed no significant variation before and after chemotherapy (all P > 0.05). Maximum TVM showed a significant positive correlation with left ventricular ejection fraction (LVEF) (all p < 0.05). Furthermore, the cut-off value with 0.23 of 3-dimensional T/QRS ratio (the area under the curve [AUC] 0.725) for differentiating LVEF reduction ≥10% following initiation of chemotherapy. The AUC of the front plane T/QRS ratio and horizontal plane T/QRS ratio for the detection of an LVEF reduction ≥10% was 0.725 and 0.763, respectively.
Conclusions
3D-VCGs can be used to detect electrophysiological abnormalities in BC patients receiving chemotherapy. Subclinical cardiac dysfunction can be revealed by 3D-VCGs before alterations in traditional echocardiographic parameters.

Abstract
AIM A high cholesterol diet (HCD) is known to cause metabolic dysregulation, oxidative stress, cardiovascular diseases and atherogenesis. Zingerone is a pharmacologically active component of dry ginger. Zingerone has been shown to have a wide range of pharmacological properties, including scavenging free radicals, high antioxidant activity, suppressing lipid peroxidation and anti-inflammatory. This study aimed to investigate the effects of Zingerone on HCD-induced atherosclerosis in rats. METHODS Animals were divided into four categories (n = 6). Group I: normal control, Group II: zingerone control (20 mg/kg b.wt.), group III: HCD-induced atherosclerosis, Group IV: HCD + zingerone, respectively, for 8 weeks. RESULTS The HCD-fed rats resulted in a significant increase in an atherosclerotic lesion, lipid peroxidation, lipid profile, high-density lipoprotein concentration, cardiac markers, body weight, reduced antioxidant status, and displayed atherosclerosis. These findings were conventional by up-regulated expression of lipid regulatory genes like sterol-regulatory-element-binding protein-c (SREBP-c), fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), acetyl-CoA synthetase (ACS), liver X receptor-alpha (LXR-α), and down-regulated expression of acetyl-CoA oxidase (ACO), peroxisome proliferator-activated receptor-alpha (PPAR-α) and carnitine palmitoyl transferase-1 (CPT-1) in HCD-fed rats. These significant changes were observed in the zingerone-treated rats for the last 4 weeks. CONCLUSION These findings suggest that zingerone reduced atherosclerosis by modulated the atherosclerotic lesion, lipid profile, antioxidant status and lipid regulatory gene expression in HCD-fed rats.

Abstract
OBJECTIVE The aim of the present work was to investigate the effects and mechanisms of long non-coding RNA (lncRNA) maternally expressed gene 3 (MEG3) in cardiomyocytes injury and apoptosis induced by high glucose (HG) in vitro. MATERIALS AND METHODS HG-induced rats' cardiomyocytes with si-MEG3 transfection were constructed. Cell viability and lactate dehydrogenase (LDH) level were examined using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) and LDH assay kits, respectively. Cardiomyocytes apoptosis was detected by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) staining. The expressions of Bcl-2, Bax, cleaved caspase-9 and cleaved caspase-3 proteins were determined by Western blot. The expression of lncRNA MEG3 was measured by Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR). RESULTS Our results indicated that the expression of MEG3 was significantly upregulated in HG-treated cardiomyocytes. The downregulation of MEG3 could attenuate cardiomyocytes injury and apoptosis by decreasing the Bax/Bcl-2 ratio, cleaved caspase-9 and cleaved caspase-3 expression. CONCLUSIONS The downregulation of MEG3 could attenuate cardiomyocytes injury and apoptosis induced by HG. The molecular mechanism was associated with the inhibition of the mitochondria-mediated apoptosis pathway.

Abstract
We have previously discovered that HDAC6 regulates the DNA damage response (DDR) via modulating the homeostasis of a DNA mismatch repair protein, MSH2, through HDAC6’s ubiquitin E3 ligase activity. Here, we have reported HDAC6’s second potential E3 ligase substrate, a critical cell cycle checkpoint protein, Chk1. We have found that HDAC6 and Chk1 directly interact, and that HDAC6 ubiquitinates Chk1 in vivo and in vitro. Specifically, HDAC6 interacts with Chk1 via the DAC1 domain, which contains its ubiquitin E3 ligase activity. During the cell cycle, Chk1 protein levels fluctuate, peaking at the G2 phase, subsequently resolving via the ubiquitin-proteasome pathway, and thereby allowing cells to progress to the M phase. However, in HDAC6 knockdown non-small cell lung cancer (NSCLC) cells, Chk1 is constitutively active and fails to resolve post-ionizing radiation (IR), and this enhanced Chk1 activity leads to preferential G2 arrest in HDAC6 knockdown cells accompanied by a reduction in colony formation capacity and viability. Depletion or pharmacological inhibition of Chk1 in HDAC6 knockdown cells reverses this radiosensitive phenotype, suggesting that the radiosensitivity of HDAC6 knockdown cells is dependent on increased Chk1 kinase activity. Overall, our results highlight a novel mechanism of Chk1 regulation at the post-translational level, and a possible strategy for sensitizing NSCLC to radiation via inhibiting HDAC6’s E3 ligase activity.

Abstract
Successful drug repurposing relies on the understanding of molecular mechanisms of the target compound. Cardiac glycosides have demonstrated potent anticancer activities; however, the pharmacological mechanisms underlying their anticancer effects remained elusive, which has restricted their further development in cancer treatment. A bottleneck is the lack of comprehensive understanding about genes and signaling pathways that are altered at the early stage of drug treatment, which is key to understand how they inhibit cancer. To address this issue, we first investigated the anticancer effects of a panel of 68 naturally isolated cardiac glycosides. Our results illustrate critical structure activity relationship of these compounds on cancer cell survival. We confirmed the anticancer effect of cardiac glycoside in mouse tumor xenografts. Through RNA sequencing, quantitative PCR and immunoblotting, we show that cardiac glycoside first activated autophagy and then induced apoptosis. Further activating autophagy by rapamycin or inhibiting apoptosis by caspase inhibitor mitigated cardiac glycoside-induced cell death, whereas inhibiting autophagy by RNA interference-mediated depletion of critical autophagy genes enhanced cell death. While depletion of Na/K-ATPase, the protein target of cardiac glycosides, by RNA interference inhibited both autophagy activation and apoptosis induction by cardiac glycoside, expression of human, but not rodent Na/K-ATPase, increased cell sensitivity to cardiac glycoside. In conclusion, our analyses reveal sequential activation of autophagy and apoptosis during early stages of cardiac glycoside treatment and indicate the importance of Na/K-ATPase in their anticancer effects.

Abstract
Objective: To compare the perioperative blood loss in patients undergoing a total knee arthroplasty (TKA) across three different techniques: computer-assisted navigation surgery (CAS), patient specific instrumentation (PSI) and conventional instrumentation (CI). Methods: Ninety consecutive patients with severe knee osteoarthritis who underwent unilateral primary TKA in Peking University Third Hospital Orthopedics Department from January 2018 to December 2018 were enrolled in this prospective study. The patients were randomly divided into three groups (30 case in each group): CAS-TKA group, PSI-TKA group and CI-TKA group. The study measured intraoperative blood loss, total blood loss, hidden blood loss, decreases of hemoglobin and hematocrit, and the post-TKA blood transfusions in the three groups. One-way ANOVA was used to detect the differences among the cohorts, and LSD was used for the post-hoc test. Results: The overall intraoperative blood loss of all patients was 6 ml (5~8 ml). The mean total blood loss and hidden blood loss in CAS-TKA group, PSI-TKA group and CI-TKA group was (1 147.0±301.8) and (1 140.1±301.9)ml, (1 044.3±454.1) and (1 038.5±454.0)ml, (1 154.0±483.6) and (1 145.3±482.7)ml, respectively; there was no significant differences among the three groups (F=0.639, 0.616, both P>0.05). There were no patients who received allogeneic blood transfusion. There were no significant differences in decrease of hemoglobin and hematocrit among the three groups neither (both P>0.05). Conclusions: Compared with conventional TKA, CAS and PSI does not increase the total blood loss of TKA. However, they both demonstrate a potential benefit in reducing blood loss of TKA.

Abstract
Kirsten rat sarcoma virus oncogene homolog (KRAS) mutant lung cancer remains a challenge to cure and chemotherapy is the current standard treatment in the clinic. Hence, understanding molecular mechanisms underlying the sensitivity of KRAS mutant lung cancer to chemotherapy could help uncover unique strategies to treat this disease. Here we report a compound library screen and identification of cardiac glycosides as agents that selectively enhance the in vitro and in vivo effects of chemotherapy on KRAS mutant lung cancer. Quantitative mass spectrometry reveals that cardiac glycosides inhibit DNA double strand break (DSB) repair through suppressing the expression of UHRF1, an important DSB repair factor. Inhibition of UHRF1 by cardiac glycosides was mediated by specific suppression of the oncogenic KRAS pathway. Overexpression of UHRF1 rescued DSB repair inhibited by cardiac glycosides and depletion of UHRF1 mitigated cardiac glycoside-enhanced chemotherapeutic drug sensitivity in KRAS mutant lung cancer cells. Our study reveals a targetable dependency on UHRF1-stimulated DSB repair in KRAS mutant lung cancer in response to chemotherapy.

Abstract
Background Stimuli-responsive gold nano-assemblies have attracted attention as drug delivery systems in the biomedical field. However, there are challenges achieving targeted delivery and controllable drug release for specific diseases. Materials and Methods In this study, a glutathione (GSH)-modified fluorescent gold nanoparticle termed AuLA-GSH was prepared and a Co2+-induced self-assembly drug delivery platform termed AuLA-GSH-Co was constructed. Both the pH-responsive character and drug loading behavior of AuLA-GSH-Co were studied in vitro. Kidney-targeting capability was investigated in vitro and in vivo. Finally, the anti-fibrosis efficiency of AuLA-GSH-Co in a mouse model of unilateral ureteral obstruction (UUO) was explored. Results AuLA-GSH-Co was sensitive to pH changes and released Co2+ in acidic conditions, allowing it to have controllable drug release abilities. AuLA-GSH-Co was found to improve cellular uptake of Co2+ ions compared to CoCl2 in vitro. AuLA-GSH exhibited specific renal targeting and prolonged renal retention time with low non-specific accumulation in vivo. Moreover, the anti-fibrosis efficiency of AuLA-GSH-Co was higher compared to CoCl2 in a mouse model of unilateral ureteral obstruction (UUO). Conclusion AuLA-GSH-Co could greatly enhance drug delivery efficiency with renal targeting capability and obviously relieve renal fibrosis, providing a promising strategy for renal fibrosis therapy.

Abstract
Shikonin is a natural naphthoquinone compound and has demonstrated potent anti-cancer activities; however, the underlying molecular mechanisms remained elusive. Here we report that Shikonin inhibited the growth of a wide range of human cancer cell lines, illustrating a broad anticancer effect. Mechanistically, we show that Shikonin arrested the cell cycle at the G2/M phase, inhibited the ERK-dependent cell growth signal, and induced cell death in both P53 wild type and mutant cancer cells, which collectively contributed to the growth inhibitory effect of Shikonin. A pan-apoptosis inhibitor largely suppressed Shikonin-induced cell death, suggesting an important role of apoptosis in this process. Intriguingly, Shikonin also activated autophagy and inhibition of autophagy by depleting critical autophagic genes further increased Shikonin-induced cell death, indicating a protective role of autophagy. In uncovering the molecular mechanisms underlying these effects of Shikonin, we found that Shikonin induced a robust upregulation of P21 independent of the P53 status, upregulated autophagy genes, as well as inhibited expression of genes required for cell growth. Using mouse tumor models, we confirmed the strong anticancer effect of Shikonin in vivo. Together, our data reveal a broad range of pharmacological functions of Shikonin, involving simultaneous growth inhibition, cell cycle arrest, autophagy activation and apoptosis induction through regulating expression of critical genes involved in these pathways. Our study may facilitate the development of Shikonin in cancer therapy as a single agent or in combination with other anticancer therapies.

Abstract
Introduction
This study was performed to investigate the differences in blood pressure among different groups of snoring children and among different sleep stages.In recent years, the incidence of OSAS in children has increased year by year. Blood pressure research of OSAS children can better understand the occurrence of OSAS related complications. Early detection and intervention of blood pressure changes in children with OSAS can effectively reduce the incidence of cardiovascular disease in adulthood and lower the disease burden.
Methods
Habitually snoring children (snoring frequency of ≥3 nights per week) aged 3to 11 years were recruited from Beijing Children’s Hospital, Capital Medical University from 1 January 2017 to 30 June 2018. All children underwent polysomnography, and their blood pressure was monitored and calculated by the pulse transit time. The children were divided into those with primary snoring (PS), mild obstructive sleep apnea syndrome (OSAS), and moderate to severe OSAS according to their obstructive apnea-hypopnea index (OAHI).
Results
In total, 140 children were recruited. Ninety-seven had PS, 24 had mild OSAS, and 19 had moderate to severe OSAS. There were no differences in age, sex, or body mass index z-score among the groups. Statistically significant differences were found in the OAHI, oxygen desaturation index 3%, respiratory arousal index, and lowest oxygen saturation among the three groups. Children with moderate to severe OSAS had higher systolic and diastolic blood pressure than those with mild OSAS and PS (P < 0.001). In all children, systolic and diastolic blood pressure was higher in the rapid eye movement (REM) sleep stage than in the non-REM sleep stage (P < 0.05).
Conclusion
Children with moderate to severe OSAS had higher blood pressure than those with PS and mild OSAS. Blood pressure in the REM sleep stage was higher than that in other sleep stages in all groups of children.

Abstract
BACKGROUND AND PURPOSE Hereditary sensory and autonomic neuropathies (HSANs) are a group of clinically and genetically heterogeneous neurological disorders characterized by sensory dysfunctions. Here, 21 affected Chinese families are reported, including 19 with congenital insensitivity to pain with anhidrosis (CIPA; namely HSAN IV) and two with congenital insensitivity to pain (CIP; namely HSAN IID) caused by biallelic variations in NTRK1 and SCN9A, respectively, aiming to identify causative variants in these families and compare how different variants in NTRK1 affect the function of tropomyosin receptor kinase A (TrkA). METHODS Recombinant plasmids harboring the wild-type and six mutant alleles (p.Gln216*, p.Glu584Lys, p.Leu595Arg, p.Pro684Leu, p.Val709Leu and p.Arg765Cys) of NTRK1 cDNA were constructed and transfected into HEK293 cells. RESULTS The results suggested that the five missense variants only presented a subtle influence on the expression level and glycosylation of TrkA but compromised the receptor phosphorylation. Our findings also suggested that a synonymous variant c.219C>T in NTRK1 may cause aberrant splicing, indicating a potential novel pathogenic mechanism of CIPA. Furthermore, gross deletion of SCN9A was first associated with CIP. CONCLUSIONS This study identified multiple forms of variants responsible for CIPA/CIP in the Chinese population and might provide new insights into the pathogenesis of CIPA.

Abstract
Objective: To investigate the current status of the occupational hazards of welding fume, manganese, and manganese compounds in the welding environment of a large container manufacturing enterprise, as well as the status of occupational health examination of workers, and to provide a basis for improving the welding environment of this enterprise. Methods: In August 2016, July 2017, and August 2018, convenience sampling was used to perform an on-site occupational hygiene survey of the welding workshop for three consecutive years, and welding fume, manganese and, manganese compounds (counted as manganese dioxide) were measured for their workplace exposure concentrations and exposure levels in workers. A comprehensive analysis was performed for the results of occupational health examination. Results: Welding fume, manganese, and manganese compounds in the welding environment gradually increased from 2016 to 2018 (χ(2)(trend)=5.14 and 5.54, P<0.05). The maximum over-standard rate of concentration-short term exposure limit was 43.3% (13/30) for welding fume and 40.0% (12/30) for manganese and its compounds, and the maximum over-standard rate of time-weighted average concentration was 26.7% (8/30) for welding fume and 23.3% (7/30) for manganese and its compounds. Abnormalities were observed in the occupational health examination of welding workers in 2016-2018, among which respiratory system abnormalities (cough, expectoration, and wheezing), nervous system abnormalities (dizziness, fatigue, sleep disorders, amnesia, hyperhidrosis, and palpitations), and electrocardiogram abnormalities (bundle conduction block) had an incidence rate of above 10.0%, and the incidence rate of abnormalities on posterior-anterior X-ray high-kV chest radiograph was close to 8.9% (30/336) . Conclusion: There is severe exposure to welding fume, manganese, and manganese compounds among workers in this enterprise, which cause great hazards to the health of workers. It is necessary to strengthen occupational health management, take measures to improve the welding environment, and enhance occupational disease prevention.

Abstract
Background Both quantitative and qualitative aspects of plasma cell‐free DNA (plasma cfDNA, pcfDNA) have been well‐studied as potential biomarkers in non‐small cell lung cancer (NSCLC). Accumulating evidence has proven that saliva also has the potential for the detection and analysis of circulating free DNA (saliva cfDNA, scfDNA). Methods In the current study, we aimed to explore the potential application of scfDNA in NSCLC diagnostics and consistency of epidermal growth factor receptor (EGFR) mutation detection in paired pcfDNA and scfDNA using droplet digital PCR (ddPCR) and analyze the relationship between EGFR mutations and clinical treatment response. Results In the quantitative cohort study, scfDNA concentration in NSCLC patients was no different from that in healthy donors, or in benign patients. ScfDNA concentration was significantly lower than pcfDNA concentration, yet they were not statistically significant in relevance (Spearman's rank correlation r = −0.123, P = 0.269). In the qualitative cohort study, the overall concordance rate of EGFR mutations between pcfDNA and scfDNA was 83.78% (31 of 37; k = 0.602; P < 0.001). EGFR mutation detection in paired pcfDNA and scfDNA was significantly correlated with the clinical treatment response (Spearman's rank correlation r = 0.664, P = 0.002). Conclusions Our results demonstrated that saliva might not be the idea material for a cfDNA quantitative test, and scfDNA concentration is not applicable for NSCLC diagnostics. Conversely, scfDNA was capable of acting as the supplement for EGFR mutations due to the coincidence rate of EGFR mutation detection between scfDNA and pcfDNA.

Abstract
Objective: To investigate the role of microRNA-29b-3p (miRNA-29b-3p) and miRNA-34c-3p in the process of pulmonary fibrosis, we detected the expression levels of miRNA-29b-3p and miRNA-34c-3p in the lung tissue of rats exposed to silica and A549 cells. Methods: SPF male Wistar rats were randomly divided into 1, 7, 14, 21, 28 d control group and silica (SiO(2)) dusting group, with 6 rats in each group. One-time non-exposure method was used to infuse 1ml SiO(2) suspension. The rat SiO(2) dusting group was established in the liquid, and the control rats were intratracheally injected with 1 ml of sterile physiological saline in the same manner. The lung tissues of each group were collected at the corresponding time points after dusting. Three of the rats were taken out for pathological observation, and the other three were used to screen differentially expressed miRNAs in lung tissue by miRNA microarray technology. A549 cells were cultured at the in vitro cell level and divided into control group, SiO(2) stimulation group and TGF-β(1) stimulation group, and cells were collected at 12, 24 and 48 h after treatment. The expression levels of miRNA-29b-3p and miRNA-34c-3p in rat lung tissue and A549 cells were verified by real-time PCR (qRT-PCR), target gene prediction of miRNA-29b-3p and miRNA-34c-3p and perform GO enrichment analysis and KEGG pathway analysis. Results: The weight growth rate of the control group was significantly higher than that of the SiO(2) dusting group. Compared with the control group, the lung mass and lung coefficient of the SiO(2) dusting group were significantly increased (P<0.05). The inflammatory response of the lungs in the control group was significantly reduced at 21 and 28 days, and the inflammatory cells infiltrated in the lung tissue of the SiO2 group. The rats in the control group had a small amount of collagen at 21 and 28 days. A large amount of collagen fiber deposition began to appear in the lung tissue of rats exposed to SiO(2) for 21 days. Compared with the control group, the expression levels of miRNA-29b-3p and miRNA-34c-3p in the SiO(2) dusting group were significantly down-regulated, and there was significant difference compared with the control group (P<0.05). The expression levels of miRNA-29b-3p and miRNA-34c-3p in A549 cells treated with SiO(2) and human recombinant TGF-β1 were significantly lower than those in the control group at 24 h and 48 h, and the difference was statistically significant (P<0.05). Conclusion: Down-regulation of miRNA-29b-3p and miR-34c-3p in rat lung tissue A549 cells may be associated with the development of early silicosis and is expected to be an indicator of early silicosis diagnosis and prognosis.

Abstract
The renoprotective effects of hypoxia inducible-factor (HIF) activators have been demonstrated by improving renal hypoxia in chronic kidney disease. Cobalt chloride is one of the most widely used HIF activators in biomedicine; however, poor kidney targeting and undesirable side effects greatly limit its clinical applications. Here, we report a novel stimuli-responsive drug release nanoplatform in which glutathione (GSH)-modified Au nanoparticles (GLAuNPs) and Co2+ self-assemble into nanoassemblies (GLAuNPs-Co) through coordination interactions between empty orbitals of Co2+ and lone pairs of GSH. The GLAuNPs, when used as a drug carrier, demonstrated high drug loading capacity and pH-triggered drug release after assembling with Co2+. The acidic environment of lysosomes in renal fibrosis tissues could disassemble GLAuNPs-Co and release Co2+. Moreover, encapsulation of the Co2+ ions in the GLAuNPs greatly lowered the cytotoxicity of Co2+ in kidney tubule cells. Tissue fluorescence imaging showed that GLAuNPs-Co specifically accumulated in the kidneys, especially in the renal proximal tubules. After GLAuNPs-Co was intraperitoneally injected into ureter-obstructed mice, significant attenuation of interstitial fibrosis was exhibited. The beneficial effects can be mainly ascribed to miR-29c expression restored by HIF-α activation. These findings revealed that GLAuNPs-Co have pH-responsive drug release and renal targeting capabilities; thus, they are a promising drug delivery platform for treating kidney disease.

Abstract
Background Temozolomide-perillyl alcohol conjugate (NEO212), a novel temozolomide (TMZ) analog, was previously reported to exert its anti-cancer effect in non-small cell lung cancer (NSCLC), and human nasopharyngeal carcinoma (NPC), etc.. In the current study, we intend to illuminate the potential anticancer property and the underly mechanisms of NEO212 in ovarian cancer cells. Methods The cytotoxicity of NEO212 was detected by MTT, colony formation analysis and xenograft model. The proteins involved in cell proliferation, DNA damage, autophagy and lysosomal function were detected by western blots; mitochondria, lysosome and autophagosome were visualized by TEM and/or immunofluorescence; Apoptosis, cell cycle analysis and mitochondrial transmembrane potential were detected by flow cytometry. TFEB translocation was detected by immunofluorescence and western blot. Results NEO212 has the potential anticancer property in ovarian cancer cells, as evidence from cell proliferation inhibition, G2/M arrest, DNA damage, xenograft, mitochondrial dysfunction and apoptosis. Importantly, we observed that although it induced significant accumulation of autophagosomes, NEO212 quenched GFP-LC3 degradation, down-regulated a series of lysosome related gene expression and blocked the autophagic flux, which significantly facilitated it induced apoptosis and was largely because it inhibited the nuclear translocation of transcription factor EB (EB). Conclusions NEO212 inhibited TFEB translocation, and impaired the lysosomal function, implying NEO212 might avoid from autophagy mediated chemo-resistance, thus proposing NEO212 as a potential therapeutic candidate for ovarian cancer.

Abstract
AIMS To investigate the associations among heteroplasmy levels (i.e. the proportions of mutant and wild-type mitochondrial DNA in the same cell), mitochondrial function and clinical severity of the m.3243A>G mutation. METHODS A total of 17 participants carrying the m.3243A>G mutation and 17 sex- and age-matched healthy controls were included in this study. Heteroplasmy levels of the m.3243A>G mutation in leukocytes, saliva and urine sediment were determined by pyrosequencing. The clinical evaluation included endocrinological, audiological and ophthalmological examinations. Mitochondrial function was determined in peripheral blood mononuclear cells isolated from participants. RESULTS Heteroplasmy levels in urine sediment were higher than those in leukocytes and saliva. Reduced levels of adenosine triphosphate and mitochondrial membrane potential, and increased reactive oxygen species production were observed in mutant peripheral blood mononuclear cells (all P < 0.05). Linear regression analysis indicated that higher heteroplasmy levels in peripheral blood leukocytes were associated with increased levels of glycated albumin and HbA1c , and decreased total hip bone mineral density T-score after adjustment for age and sex (all P < 0.05). Furthermore, mitochondrial membrane potential was independently associated with bone mineral density T-score at the femoral neck (P < 0.05). CONCLUSIONS Heteroplasmy levels in peripheral blood leukocytes and mitochondrial membrane potential in peripheral blood mononuclear cells were closely associated with clinical manifestations and were valuable for evaluation of the clinical severity of the m.3243A>G mutation.

Abstract
This study aimed to unravel the molecular mechanism of oral squamous cell carcinoma (OSCC). With microarray dataset GSE30784, differentially expressed genes (DEGs) were identified between OSCC and control samples. The DEGs overlapped with genes obtained from online database MalaCards were determined as OSCCDEG, followed by Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. A total of 5177 up-regulated and 6081 down-regulated DEGs were identified between OSCC and control. Out of the DEGs, 451 genes were overlapped with the 704 genes gained from MalaCards and regarded as "OSCCDEG". Up-regulated OSCCDEG were associated with cell cycle pathway, while down-regulated OSCCDEG were linked to ErbB pathway. ANGPT1, ANGPT2 and 3 hub proteins (EGFR, HSP90AA1, RB1) in the PPI network were associated with the survival rates of several tumors. The largest network module with the hub protein EGFR was associated with positive regulation of cell communication. The second largest module with the hub node FN1 was related to angiogenesis. For the third network module in connection with DNA metabolism, the hub protein was PCNA. ErbB and cell cycle pathways were crucial for OSCC. EGFR, FN1, PCNA, ANGPT1 and ANGPT2 might be potential biomarkers for OSCC. These findings help provide guidelines for treating OSCC.

Abstract
Purpose HER2-targeted therapies have substantially improved the outcome of patients with breast cancer, however, they can be associated with cardiac toxicity. Guidelines recommend holding HER2-targeted therapies until resolution of cardiac dysfunction. SAFE-HEaRt is the first trial that prospectively tests whether these therapies can be safely administered without interruptions in patients with cardiac dysfunction. Methods Patients with stage I–IV HER2-positive breast cancer candidates for trastuzumab, pertuzumab or ado-trastuzumab emtansine (TDM-1), with left ventricular ejection fraction (LVEF) 40–49% and no symptoms of heart failure (HF) were enrolled. All patients underwent cardiology visits, serial echocardiograms and received beta blockers and ACE inhibitors unless contraindicated. The primary endpoint was completion of the planned HER2-targeted therapies without developing either a cardiac event (CE) defined as HF, myocardial infarction, arrhythmia or cardiac death or significant asymptomatic worsening of LVEF. The study was considered successful if planned oncology therapy completion rate was at least 30%. Results Of 31 enrolled patients, 30 were evaluable. Fifteen patients were treated with trastuzumab, 14 with trastuzumab and pertuzumab, and 2 with TDM-1. Mean LVEF was 45% at baseline and 46% at the end of treatment. Twenty-seven patients (90%) completed the planned HER2-targeted therapies. Two patients experienced a CE and 1 had an asymptomatic worsening of LVEF to ≤ 35%. Conclusion This study provides safety data of HER2-targeted therapies in patients with breast cancer and reduced LVEF while receiving cardioprotective medications and close cardiac monitoring. Our results demonstrate the importance of collaboration between cardiology and oncology providers to allow for delivery of optimal oncologic care to this unique population.

Abstract
The ability to further stratify patients with esophageal carcinoma (EC) in the same stage into high-risk patients by the presence of lymphovascular invasion (LVI) may permit refinement of multi-modality therapy. However, the role of LVI in the prognosis of EC is not definite. A meta-analysis was conducted to investigate the relationship between LVI and EC prognosis. We searched PubMed, Embase, Web of Science, and Cochrane Library databases for studies on the association between LVI and prognosis of EC. Only studies with patient survival data related to LVI were included. The effect size for this analysis was the hazard ratio (HR) with 95% confidence intervals (CI) for overall survival (OS) and recurrence-free survival (RFS). Thirty-five studies with 9876 patients were included according to the defined inclusion and exclusion criteria. LVI was a poor indicator for the OS (HR = 1.64, 95% CI: 1.44-1.87, P < 0.001) and RFS (HR = 1.79, 95% CI: 1.38-2.34, P < 0.001). However, the heterogeneity was medium in OS (I2 = 61.2%, P < 0.001) and extreme in RFS (I2 = 77.5%, P < 0.001). In subgroup analysis, heterogeneity was originated from the staining method and proportion of early disease (stage (I + II)). We concluded that LVI was a poor prognostic indicator in patients with EC, especially in those studies with the IHC staining method and a high proportion of early disease (stage (I + II)).

Abstract
Objective: To observe the mid-term clinical outcome of total knee arthroplasty (TKA) with domestic A3 posterior stabilized prosthesis. Methods: The clinical data of 342 patients (438 knees) who underwent primary TKA by the same surgeon from June 2012 to December 2013 in Peking University Third Hospital were retrospectively collected. The patients were divided into 2 groups according to the type of prosthesis: 107 patients (137 knees) with domestic A3 prosthesis, as domestic group; 235 patients (301 knees) with a kind of imported prosthesis, as the control group. In the end, 311 patients (390 knees) received complete follow-up.The postoperative knee maximum flexion angle, postoperative Hospital for Special Surgery Knee Score (HSS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), postoperative coronal mechanical axis alignment and hospitalization costs were compared between the groups.Paired t-test was used to compare the preoperative and postoperative data in the same group, and independent sample t-test was used to compare the data between the two groups at the same time points. Results: The average follow-up time of all the patients was (5.6±1.1) years, and it was averaged for 64.8 months in the domestic group and 68.2 months in the control group.There was no significant difference in the HSS score and WOMAC score, the knee maximum flexion angle, and coronal mechanical axis alignment at the 3 months postoperatively and at the end of follow-up between the two groups (t=-0.890, -1.610, 1.740, 0.620, all P>0.05). In 2012, the average hospital cost was (24 879±1 627) yuan/knee in the domestic group and it was (49 611±1 589) yuan/knee in the control group (t=-48.902, P<0.01). In 2013, it was (38 393±2 773) yuan/knee in the domestic group, and was (55 931±3 533) yuan/knee in the control group (t=-14.795, P<0.01). Conclusion: It indicates that the domestic A3 posterior stabilized prosthesis brings comparable mid-term results with the imported prothesis and it reduces medical costs remarkably.

Abstract
Small-sized cationic miRi (microRNA-21 inhibitor)-PCNPs (low molecular weight chitosan (LMWC)-modified polylactide-co-glycoside (PLGA) nanoparticles (PLNPs)) with special kidney-targeting and high-efficiency antifibrosis treatment are fabricated through coupling miRi, PLGA, and LMWC. In the miRi-PCNPs, easily degraded miRi is encapsulated in PCNPs and thus prevented from degradation by nuclease. Cytotoxicity, immunotoxicity, and systemic toxicity assays and in vitro and ex vivo fluorescence imaging suggest that PCNPs possess excellent biocompatibility, higher cellular uptake efficiency, and selective kidney-targeting capacity. Western blotting, pathological staining, and real-time polymerase chain reaction analyses show that the therapeutic effect of miRi-PCNPs on kidney fibrosis is much higher than that of miRi, which is mainly through suppressing transforming growth factor beta-1/drosophila mothers against decapentaplegic protein 3 (TGF-β1/Smad3) and extracellular signal-regulated kinases/mitogen-activated protein kinase signaling pathway by inhibiting the expression of microRNA-21. For example, the tubule damage index and tubulointerstitial fibrosis area in the miRi-PCNPs group are ≈2.5-fold lower than those in the saline and bare miRi groups. The miRi-PCNPs with special kidney-targeting and high-efficiency antifibrosis treatment may represent a promising strategy for designing and developing a therapeutic treatment for kidney fibrosis.

Abstract
BACKGROUND Temozolomide-perillyl alcohol conjugate (TMZ-POH), a novel Temozolomide (TMZ) analog developed based on the conjugation of TMZ and perillyl alcohol (POH), displayed strong anticancer potency in multiple cancer types. In this study, we aimed to clarify the relationship between TMZ-POH and autophagy, and explore the underlying mechanisms involved in. METHODS The proteins involved in autophagy, mitochondrial fission, lysosomal function and membrane traffic were detected by western blots; Autophagosome, mitochondria and lysosome were visualized by transmission electron microscope (TEM) and immunostaining; Apoptosis analysis and fluorescence probe detection were applied by flow cytometry. RESULTS TMZ-POH blocked mitophagy flux although the number of autophagosomes which colocalized with mitochondria in the cells was increased via inducing lysosomal dysfunction as evidence from impaired lysosomal acidification, maturation and hampered autophagosome- lysosome fusion, which largely depended on its downregulation on the small GTPase RAB7A via mevalonate pathway. More importantly, our data demonstrated TMZ-POH sensitized cancer cell to irradiation induced apoptosis. CONCLUSIONS Temozolomide-perillyl alcohol conjugate impairs mitophagy flux by inducing lysosomal dysfunction in Non-Small Cell Lung Cancer (NSCLC) cells and sensitizes them to irradiation, thereby proposing TMZ-POH as a potential radiosensitizer.

Abstract
Objective: To explore the prevalence and clinical characteristics of postprandial hypotension(PPH) in patients with essential hypertension and coronary heart disease. Methods: A total of 197 patients with essential hypertension and coronary heart disease, who had been treated in the First Department of Cardiology of the Second Hospital of Hebei Medical University from December, 2013 to December, 2014 were included. The patients' blood pressure before breakfast, lunch and dinner and 30, 60, 90, 120 minutes after the meal were monitored. Subjects were classified into PPH group (n=37) and non-PPH group (NPPH, n=160) according to postprandial decrease in systolic blood pressure, to explore the clinical characteristics and related factors and the major adverse cardiac and cerebral vascular events of PPH. Results: Among 197 patients, 37 cases (18.8%) showed at least once postprandial decline in systolic blood pressure greater than and equal to 20 mmHg. The incidence of PPH after breakfast and dinner were higher than lunch (P<0.05). There was no significant difference in the incidence of PPH among different age groups, among patients accompanied with different diseases, and among patients with different dining position (all P>0.05). According to the baseline systolic blood pressure, patients can be divided into 4 groups(<120 mmHg, 120-129 mmHg, 130-139 mmHg, >140 mmHg), the higher the level of the baseline systolic blood pressure was, the higher the incidence of PPH was. And the incidence of major adverse cardiac and cerebral vascular events in patients during hospitalization were increased by PPH. Conclusions: The prevalence of PPH in the patients with essential hypertension and coronary heart disease is 18.8%. The incidence of PPH after breakfast and dinner is higher than lunch. The baseline systolic blood pressure is considered to be the risk factor of PPH. And PPH could lead to an increase of the incidence of major adverse cardiac and cerebral vascular events.
