Abstract
OBJECTIVE This paper aims to investigate the correlation of lipid peroxide in erythrocytes and ATP (Adenosine Triphosphate) enzyme activity of erythrocyte membrane with fetal distress in patients with intrahepatic cholestasis of pregnancy (ICP). PATIENTS AND METHODS Forty-three patients with ICP treated at Jining No. 1 People's Hospital were enrolled as a study group, and another forty healthy parturient women in the same period were enrolled as a control group, to extract their elbow venous blood and fetal umbilical cord blood. Thiobarbituric acid (TBA) was used to detect superoxide dismutase (SOD) activity of erythrocytes, malondialdehyde (MDA) activity in plasma, Na+-K+-ATP enzyme activity and Ca2+-Mg2+-ATP enzyme activity of erythrocytes, which were compared between the study and control groups. The correlation of MDA, Na+-K+-ATP enzyme and Ca2+-Mg2+-ATP enzyme activities with fetal distress in the study group was analyzed, and the correlation of MDA with Na+-K+-ATP enzyme activity was investigated. RESULTS SOD and MDA activities of erythrocytes in maternal blood of the study group were significantly higher than those in the control group (p<0.05, p<0.001, respectively), but MDA activity in umbilical cord blood of the study group was markedly higher than that in the control group (p<0.001). Na+-K+-ATP enzyme and Ca2+-Mg2+-ATP enzyme activities of maternal and fetal erythrocytes of the study group were remarkably lower than those of the control group (p<0.001). MDA in the fetal distress group was significantly higher than that in the no fetal distress group in the study group (p<0.001). Na+-K+-ATP enzyme activity was negatively correlated with MDA concentration in maternal and fetal erythrocytes of patients with ICP (both p<0.001). CONCLUSIONS Lipid peroxidation in patients with ICP will affect ATP enzyme activity of erythrocyte membrane, and the down-regulation of ATP enzyme activity in umbilical cord blood of patients with ICP may cause fetal distress in the uterus.

Abstract
A wealth of epidemiological evidence, combined with plausible biological mechanisms, present a convincing argument for a causal relationship between excess adiposity, commonly approximated as body mass index (BMI, kg/m2), and incident cancer risk. Beyond this relationship, there are a number of challenges posed in the context of interpreting whether being overweight (BMI 25.0-29.9 kg/m2) or obese (BMI ≥ 30.0 kg/m2) adversely influences disease progression, cancer mortality and survival. Elevated BMI (≥ 25.0 kg/m2) may influence treatment selection of, for example, the approach to surgery; the choice of chemotherapy dosing; the inclusion of patients into randomised clinical trials. Furthermore, the technical challenges posed by an elevated BMI may adversely affect surgical outcomes, for example, morbidity (increasing the risk of surgical site infections), reduced lymph node harvest (and subsequent risk of under-staging and under-treatment) and increased risk of margin positivity. Suboptimal chemotherapy dosing, associated with capping chemotherapy in obese patients as an attempt to avoid excess toxicity, might be a driver of poor prognostic outcomes. By contrast, the efficacy of immune checkpoint inhibition may be enhanced in patients who are obese, although in turn, this observation might be due to reverse causality. So, a central research question is whether being overweight or obese adversely affects outcomes either directly through effects of cancer biology or whether adverse outcomes are mediated through indirect pathways. A further dimension to this complex relationship is the obesity paradox, a phenomenon where being overweight or obese is associated with improved survival where the reverse is expected. In this overview, we describe a framework for evaluating methodological problems such as selection bias, confounding and reverse causality, which may contribute to spurious interpretations. Future studies will need to focus on prospective studies with well-considered methodology in order to improve the interpretation of causality.

Abstract
OBJECTIVE To investigate the correlations of analgesic dosage of morphine with solute carrier family 6 member 4 (SLC6A4) gene polymorphisms in patients with lung cancer. PATIENTS AND METHODS A total of 200 lung cancer patients without cancer pain were selected as painless group, and another 200 lung cancer patients with cancer pain as cancer pain group. Visual Analogue Scale (VAS) was applied to grade the pain, the patients in cancer pain group were treated with morphine, and the dosage of morphine within 24 h was recorded. Then, the genomic deoxyribonucleic acid (DNA) was extracted from the peripheral blood of the research subjects, and the polymorphisms rs1042173 and rs7224199 of SLC6A4 gene were detected. RESULTS There was a difference in the genotype distribution of SLC6A4 gene rs7224199 between painless group and cancer pain group (p=0.004), and the frequency of GG genotype was remarkably higher in cancer pain group [75 (0.375)]. The frequency of heterozygous model AC of rs1042173 and recessive model GT + TT of rs7224199 in cancer pain group was evidently lower than that in painless group (p=0.048, p=0.043). Besides, the lung cancer patients in cancer pain group had markedly lower frequency of AG haplotype (p=0.000), but notably higher frequency of AT (p=0.000) and CG (p=0.000) haplotypes of SLC6A4 gene rs1042173 and rs7224199 than those in painless group. No significant differences in genotypes of SLC6A4 gene rs1042173 (p=0.241) and rs7224199 (p=0.316) were detected among the degrees of cancer pain in cancer pain group. The analgesic dosage of morphine for the lung cancer patients was prominently correlated with the genotypes of SLC6A4 gene rs1042173 in cancer pain group. Moreover, in cancer pain group, there were significant differences in the dosage within 24 h (p=0.025), at 24 h after weight correction (p=0.001) and at 24 h after correction of weight and body surface area (p=0.000) among the genotypes, and the morphine dosage for the patients with CC genotype was significantly lower. Furthermore, the morphine dosage within 24 h (p=0.047), at 24 h after weight correction (p=0.042) and at 24 h after correction of weight and body surface area (p=0.031) were distinctly associated with the haplotypes of SLC6A4 gene in cancer pain group, of which the patients with CT haplotype were administered with a remarkably lower morphine dosage. CONCLUSIONS The morphine dosage for analgesia has significant correlations with SLC6A4 gene polymorphisms in patients with lung cancer.

Abstract
Symbiotic plants might be able to regulate a limited nitrogen (N) pool, thus avoiding and reducing competition for resources, through the uptake of different chemical N forms. Our aim was to see whether coexisting herbs showed preference for different forms of N in a temperate desert. We conducted a situ experiment using the 15 N labeling method in the Gurbantunggut Desert of Northwestern China dominated by Erodium oxyrrhynchum, Hyalea pulchella, Nonea caspica and Lactuca undulata during their growing period (April and May). Four desert herb species preferentially relied on 15 N-NO3 for their N nutrition. Multi-factor analysis of variance (ANOVA) analysis results showed that species, N forms, months, and soil depths strongly affected N uptake rate. The uptake rate by herbs was higher in May than in April, and higher at 0-5 cm than at 5-15 cm soil layers. Erodium oxyrrhynchum, N. caspica and L. undulata showed different preference on N form over months. Erodium oxyrrhynchum and L. undulata changed their uptake preference from more 15 N-Glycine in April to more 15 N-NH4 in May. Although the N uptake rate of four desert herbs varied across different soil depths and months, all species absorbed more inorganic N compared with organic N. The higher preference for 15 N-NO3 and 15 N-NH4 over 15 N-Gly possibly reflects adaptation to different N forms in temperate desert.

Abstract
Neuropathic pain (NP) after spinal cord injury (SCI) leads to compromised physical and cognitive functions in a majority of patients. Aberrant miRNA expression plays vital roles in the pathogenesis of SCI. This study aims to investigate the effect of miR-331-3p in rats following SCI. Microarray assay was performed in SCI- and sham-operated rats to evaluate the expression of miR-331-3p. Assigned SCI rats were treated with miR-331-3p agomiR alone or miR-331-3p agomiR plus RAP1A-expressing lentivirus or control agomiR. Rat locomotor performance was evaluated by BBB locomotor rating scale. Neuronal tissue damage and apoptosis were detected by histological analyses and Western blot. Inflammation in spinal cord was determined by detection of the expression of inflammatory genes with qRT-PCR, and ELISA. Downstream expression of RAP1A was measured by Western blot. The results showed that SCI induced the downregulation of miR-331-3p in the spinal cord of SCI rats. Overexpression of miR-331-3p improved the locomotor performance, reduced tissue damage, neuronal apoptosis and inflammation in rat SCI model. Rap1a (Ras-related protein Rap-1A) was predicted as a downstream target for miR-331-3p, and upregulation of RAP1A impaired the beneficial effect of miR-331-3p post- SCI, which was shown as worse locomotor activity, more severe tissue damage, as well as promoting apoptosis and inflammation in SCI rats. Furthermore, miR-331-3p reduced the activation of RAP1A downstream genes via inhibiting RAP1A expression. These findings indicate a protective role of miR- 331-3p in the development of SCI via the modulation of RAP1A, and may help to develop novel therapy against SCI-induced complications.

Abstract
Healthy China 2030 aims to reduce the adult smoking rate from 27.7% in 2015 to 20% by 2030. Achieving this goal requires a review of the tobacco control measures introduced in China to date, the gaps that remain and the opportunities ahead. In 2008, the World Health Organization introduced six measures to reduce demand for tobacco called MPOWER. The progress China has made in implementing these measure varies: 1) monitor tobacco use and prevention policies. The surveillance on tobacco use has been rigorous, but the monitoring and evaluation of tobacco control policies needs to be strengthened; 2) protect people from tobacco use: pushes for national tobacco control legislation have stalled, but 18 subnational legislations have passed; 3) offer help to quit tobacco use. The accessibility and quality of cessation services needs to be improved; 4) warn about the dangers of tobacco. While there are no pictorial health warnings, tobacco control advocates have launched a series of anti-smoking media campaigns to inform the public; 5) enforce bans on tobacco advertising, promotion, and sponsorship. Legal loopholes and poor enforcement remain challenges; 6) raise taxes on tobacco: cigarettes in China are relatively cheap and increasingly affordable, which demonstrates the need for further tobacco tax increases indexed to inflation and income. China maintains a tobacco monopoly that interferes with tobacco control efforts and fails to regulate tobacco products from the public health perspective. Effective MPOWER measures, which depend upon the removal of tobacco industry interference from policymaking, are key to achieving the goal set by Healthy China 2030.

Abstract
OBJECTIVES Diet may change the chronic levels of systemic inflammation, which in turn influence the development of leukoaraiosis (LA). This study aimed to examine the association between dietary inflammatory index (DII) and LA in patients with ischemic stroke. METHODS Patients with first-ever ischemic stroke were enrolled from two centers. A semi-quantitative food frequency questionnaire (FFQ) was used to evaluate diet contents. The DII score of each patient was calculated based on the reported diet contents. Presence and degree of LA were evaluated with a magnetic resonance imaging (MRI) scan. LA was graded according to Fazekas scale. RESULTS Of the 497 enrolled patients, 337 (67.8%) were detected with LA. Patients with LA had a higher DII score (0.23 vs -0.88, P < 0.001). Logistic regression analysis detected that patients with highest quartile of DII score had an OR of 3.61 (95% CI: 2.05-6.36, P < 0.001) for LA compared with those with lowest quartile of DII. After adjusting for major confounders, the highest DII quartile remained as an independent predictor for LA (OR = 2.66, 95% CI: 1.41-5.00, P = 0.008). CONCLUSIONS A pro-inflammatory diet pattern, as indicated by higher DII values, appears to be associated with a higher risk of LA. This result suggested that dietary-mediated inflammation may involved in the pathogenesis of LA, which warrant further study.

Abstract
During winter in the mid-latitudes, photochemical oxidation is significantly slower than in summer and the main radical oxidants driving formation of secondary pollutants, such as fine particulate matter and ozone, remain uncertain, owing to a lack of observations in this season. Using airborne observations, we quantify the contribution of various oxidants on a regional basis during winter, enabling improved chemical descriptions of wintertime air pollution transformations. We show that 25-60% of NOx is converted to N2O5 via multiphase reactions between gas-phase nitrogen oxide reservoirs and aerosol particles, with ~93% reacting in the marine boundary layer to form >2.5 ppbv ClNO2. This results in >70% of the oxidizing capacity of polluted air during winter being controlled, not by typical photochemical reactions, but from these multiphase reactions and emissions of volatile organic compounds, such as HCHO, highlighting the control local anthropogenic emissions have on the oxidizing capacity of the polluted wintertime atmosphere.

Abstract
BACKGROUND The CDK4/6 inhibitor palbociclib prolongs progression-free survival in hormone receptor-positive/HER2-negative (HR+/HER2-) metastatic breast cancer when combined with endocrine therapy. This phase II trial was designed to determine the feasibility of adjuvant palbociclib and endocrine therapy for early breast cancer. PATIENTS AND METHODS Eligible patients with HR+/HER2- stage II-III breast cancer received 2 years of palbociclib at 125 mg daily, 3 weeks on/1 week off, with endocrine therapy. The primary end point was discontinuation from palbociclib due to toxicity, non-adherence, or events related to tolerability. A discontinuation rate of 48% or higher would indicate the treatment duration of 2 years was not feasible, and was evaluated under a binomial test using a one-sided α = 0.025. RESULTS Overall, 162 patients initiated palbociclib; over half had stage III disease (52%) and most received prior chemotherapy (80%). A total of 102 patients (63%) completed 2 years of palbociclib; 50 patients discontinued early for protocol-related reasons (31%, 95% CI 24% to 39%, P = 0.001), and 10 discontinued due to protocol-unrelated reasons. The cumulative incidence of protocol-related discontinuation was 21% (95% CI 14% to 27%) at 12 months from start of treatment. Rates of palbociclib-related toxicity were congruent with the metastatic experience, and there were no cases of febrile neutropenia. Ninety-one patients (56%) required at least one dose reduction. CONCLUSION Adjuvant palbociclib is feasible in early breast cancer, with a high proportion of patients able to complete 2 years of therapy. The safety profile in the adjuvant setting mirrors that observed in metastatic disease, with approximately half of the patients requiring dose-modification. As extended duration adjuvant palbociclib appears feasible and tolerable for most patients, randomized phase III trials are evaluating clinical benefit in this population.

Abstract
Lactobacillus paracasei subsp. paracasei L1 was previously isolated from sweet potato sour liquid. This bacterial species specifically binds onto starch granular surfaces, triggering the enzymatic hydrolysis of raw starch. We investigated the functional and safety properties of strain L1 in vitro to establish its probiotic potential, and analyzed its effect on growth performance and intestinal microflora of chicken in feeding experiments. The optimal growth conditions of strain L1 included low pH and high concentrations of bile salts and NaCl. Its 1-, 2-, and 24-h autoaggregation values were 15.8 ± 1.2%, 20.4 ± 2.3%, and 47.2 ± 0.8%, respectively, with the surface hydrophobicity value at 560 nm of 38.1 ± 2.7%. Further, its adhesion rate to Caco-2 cells was 22.37 ± 1.44%. Strain L1 was resistant to erythromycin and azithromycin, but sensitive to other antibiotics tested. For the feeding experiments, 240 chickens with similar weights were randomly divided into a control (C) group and strain L1 (L) group and fed for 8 weeks. Strain L1 promoted the weight gain of chickens in L group. A significant increase in the population size of the two phyla and 23 genera in the small intestine was observed in the presence of strain L1 (P < 0.05), with 0 phyla and 4 genera showing significant increase in the cecum (P < 0.05). In the small intestine, the abundance of six functional genes at Kyoto Encyclopedia of Genes and Genomes (KEGG) level 2 and 49 genes at KEGG level 3 was significantly increased in group L (P < 0.05), with lesser changes noted in the cecum. An increase in the metabolic pathway functions, including enzyme families and the digestive system, was observed in the intestinal microbiota in the L group compared to the C group. However, the other metabolic pathway functions, including metabolism of fatty acid biosynthesis, as well as metabolism of glycerolipids and propanoate, increased in the cecal microbiota of the L group relative to the C group. These changes are most likely related to the changes in the gut microbiota composition. Collectively, strain L1 supplementation may promote growth performance and improve the intestinal microflora in chicken although further studies are needed to confirm this.

Abstract
Objective: To explore the relationship between anthropometric indices and the incident risk of hypertension, compare novel anthropometric indices with traditional indices in hypertension prediction and establish hypertension prediction models among elderly Chinese. Methods: A total of 27 009 retirees from the Dongfeng Motor Corporation were recruited at baseline in 2008 and the first follow-up was conducted in 2013. After the exclusion of participants less than 60 years old, participants with hypertension, coronary heart disease, stroke, cancer, and those with missing data, a total of 6 784 elderly participants were enrolled in this study. A multivariate logistic regression model was used to analyze the relationship between traditional anthropometric indices, body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), novel anthropometric indices, visceral adiposity index (VAI), body shape index (ABSI), body roundness index (BRI), and the incident risk of hypertension. Meanwhile, a multivariate logistic regression model was used to establish hypertension prediction models. Receiver operating characteristic (ROC) curve was applied to compare the prediction ability of different models. Results: A total of 1 787 incident cases of hypertension were identified, with the incidence of hypertension about 27.59%. Significant positive associations were detected between BMI, WC, WHtR, VAI, BRI and the incident risk of hypertension after adjusting for potential confounders (all P values<0.05). In men, the OR (95%CI) (upper tertile vs lower tertile) was 1.45 (1.22-1.73) for VAI, and 1.86 (1.55-2.23) for BRI. In women, the OR (95% CI) (upper tertile vs lower tertile) was 1.55 (1.22-1.96) for VAI, and 1.60 (1.27-2.01) for BRI. For ABSI, no significant association was observed in either men (OR (95%CI): 1.07 (0.90-1.28)) or women (OR (95%CI): 1.03 (0.82-1.29), both P values >0.05). The basic hypertension prediction model included age, drinking (only in men), education status (only in men), systolic blood pressure (SBP), diastolic blood pressure (DBP), and fasting blood glucose levels. Based on the basic prediction model, BMI (in men: AUC=0.697) and BRI (only in men: AUC=0.696) improved area under ROC curve (AUC) significantly (P<0.05). BMI was the strongest predictor in both men (AUC=0.697) and women (AUC=0.685) in the extended model. Conclusion: Significant positive associations were detected between BMI, WC, WHtR, VAI, BRI and the incident risk of hypertension among elderly Chinese. BMI was the strongest predictor in hypertension prediction model compared with other anthropometric indices.

Abstract
Objective: To investigate the effect of the endoscopic selective varices devascularization (ESVD) for the esophageal gastric varices bleeding (EGVB) in children. Methods: The clinical data of the patients diagnosed with EGVB and treated with ESVD from January 2018 to March 2018 were retrospectively analyzed. The effects, safety and complications of ESVD were evaluated. Results: There were five patients (including 2 males and 3 females, age ranged from 4 to 7 years) in the study. No rebleeding was found at the first follow-up on one week post operation. Three patients were treated with the endo-therapy at the twice follow-up (3 months after surgery): 2 patients had ESVD again and 1 patient had resection under endoscopy due to stenosis caused by surgical scar. After the second procedure, there was no rebleeding but one patient had abdominal pain caused by mesenteric thrombosis, cured with low molecular weight heparin. Conclusion: The ESVD for EGVB is safe and effective, but the long-term curative effect should be further studied.

Abstract
AIM The association between the use of oral contraceptives and hormone replacement therapy (HRT) or other reproductive factors and the risk of colorectal adenoma (CRA) remains controversial. Our study aimed to review the evidence by conducting a dose-response meta-analysis to investigate this association. METHODS We searched PubMed and Embase databases for relevant studies published until May 2017. Traditional and dose-response meta-analyses were conducted. Sensitivity analysis was performed to evaluate the robustness of the results. Cumulative meta-analysis was used to assess the risk of different oral contraceptive formulations or generations. RESULTS A total of 19 observational studies, with 21 923 CRA cases and 1 030 711 participants, were included in the meta-analysis. Ever HRT use showed a potential inverse association with CRA risk [relative risk (RR) 0.83, 95% CI 0.70-1.00]. The dose-response meta-analysis further demonstrated that HRT use could reduce CRA risk. Compared with no HRT use, the predicted RRs were 0.82 (95% CI 0.67-0.99), 0.76 (95% CI 0.59-0.98) and 0.77 (95% CI 0.62-0.96) for 3, 6 and 9 years of HRT use, respectively. All other factors were not statistically significantly associated with CRA risk. CONCLUSIONS This study indicated that only HRT use might reduce the risk of developing CRA. Any advice regarding HRT use to prevent CRA should be tailored to the individual risks and potential benefits. Large, well-designed prospective studies with long-term follow-up are required to further clarify the aetiology of CRA.

Abstract
Sensory neurone membrane proteins (SNMPs) function as essential cofactors for insect sex pheromone detection. In this study, we report two SNMPs in Ectropis obliqua Prout, a serious geometrid pest that produces typical Type-II sex pheromones. Sequence alignments and phylogenetic analyses showed that EoblSNMP1 and EoblSNMP2 belong to two distinct SNMP subfamilies. Quantitative real-time PCR suggested that EoblSNMP1 was male antennae-biased, whereas EoblSNMP2 was highly expressed on male antennae but was also expressed on female antennae and other chemosensory tissues. Additionally, EoblSNMP1 and EoblSNMP2 differed in their developmental expression profiles. In situ hybridization revealed that EoblSNMP1 was sensilla trichodea I specific, whereas EoblSNMP2 was expressed in sensilla trichodea I and the sensilla basiconica; furthermore, EoblSNMP1 and EoblSNMP2 were co-expressed in sensilla trichodea I but in different cells. This study suggests that EoblSNMP1 is functionally distinct from EoblSNMP2 in E. obliqua; EoblSNMP1 may specifically contribute to the recognition of sex pheromones, whereas EoblSNMP2 exhibits multiple olfactory roles. Our findings comprehensively reveal the expression patterns of SNMPs in a lepidopteran species that uses Type-II sex pheromones, providing new insights into the functional evolution of SNMPs from lepidopteran moths with Type-I sex pheromones to those with Type-II sex pheromones.

Abstract
PURPOSE To explore the effects of mobile health (mHealth) intervention on pregnancy weight management, blood glucose control and pregnancy outcomes. METHODS A total of 124 patients with gestational diabetes mellitus (GDM) were selected. Patients were randomly divided into two groups. The 60 patients in the control group received standard outpatient treatment, while the remaining 64 patients received a nurse's online guidance both through a mobile medical App installed on their phone and through regular offline clinical treatment in the mHealth group. Patients were treated for an average of 13 weeks and general conditions, compliance, blood glucose, glycosylated hemoglobin, weight gain, pregnancy, and neonatal outcomes were monitored in both groups longitudinally. RESULTS The mHealth group demonstrated higher levels of compliance (83.3 ± 12.5% vs. 70.4 ± 10.1%, t = - 6.293, df = 122, p < 0.001), lower frequency of outpatient service (8.1 ± 1.3 vs. 11.2 ± 1.1, t = 14.285, df = 122, p < 0.001), lower hemoglobin A1C before delivery (4.7 ± 0.2 vs. 5.3 ± 0.3, t = 13.216, df = 122, p < 0.001) as well as the rates of off-target measurements both fasting (4.6 ± 0.4% vs. 8.3 ± 0.6%, t = 40.659, df = 122, p < 0.001) and 2 h post-prandial (7.9 ± 0.7% vs. 14.7 ± 0.8%, t = 50.746, df = 122, p < 0.001). Weight gain in the mHealth group was less than control group (3.2 ± 0.8 vs. 4.8 ± 0.7, t = 11.851, df = 122 p < 0.001). CONCLUSION Mobile health intervention management of gestational diabetes mellitus improves patients' compliance and blood glucose control, and reduces weight gain, thereby reducing the rates of complications in both pregnant women and fetuses during delivery during pregnancy.

Abstract
BACKGROUND Previous data suggest that the immune microenvironment plays a critical role in human epidermal growth factor receptor 2 (HER2) -positive breast cancer; however, there is little known about the immune profiles of small HER2-positive tumors. In this study, we aimed to characterize the immune microenvironment of small HER2-positive breast cancers included in the Adjuvant paclitaxel and trastuzumab for node-negative, HER2-positive breast cancer (APT) trial and to correlate the immune markers with pathological and molecular tumor characteristics. PATIENTS AND METHODS The APT trial was a multicenter, single-arm, phase II study of paclitaxel and trastuzumab in patients with node-negative HER2-positive breast cancer. The study included 406 patients with HER2-positive, node-negative breast cancer, measuring up to 3 cm. Exploratory analysis of tumor infiltrating lymphocytes (TIL), programmed death-ligand 1 (PD-L1) expression (by immunohistochemistry), and immune gene signatures using data generated by nCounter PanCancer Pathways Panel (NanoString Technologies, Seattle, WA), and their association with pathological and molecular characteristics was carried out. RESULTS Of the 406 patients, 328 (81%) had at least one immune assay carried out: 284 cases were evaluated for TIL, 266 for PD-L1, and 213 for immune gene signatures. High TIL (≥60%) were seen with greater frequency in hormone-receptor (HR) negative, histological grades 2 and 3, as well in HER2-enriched and basal-like tumors. Lower stromal PD-L1 (≤1%) expression was seen with greater frequency in HR-positive, histological grade 1, and in luminal tumors. Both TIL and stromal PD-L1 were positively correlated with 10 immune cell signatures, including Th1 and B cell signatures. Luminal B tumors were negatively correlated with those signatures. Significant correlation was seen among these immune markers; however, the magnitude of correlation did not indicate a monotonic relationship between them. CONCLUSION Immune profiles of small HER2-positive breast cancers differ according to HR status, histological grade, and molecular subtype. Further work is needed to explore the implication of these findings on disease outcome. CLINICAL TRIAL REGISTRATION clinicaltrials.gov identifier: NCT00542451.

Abstract
Objective: To explore the management strategy and clinical outcome of renal transplantation in presensitized recipients using deceased donor kidneys. Methods: From January 2011 to June 2018, twenty-one presensitized patients, including 8 with positive donor specific antibodies (DSA) and 13 with positive panel-reactive antibodies (PRA) but no DSA, received renal retransplantation from deceased donors in our center. The incidence of delayed graft function (DGF) and acute rejection (AR), changes of DSA, and the graft and patient survival were retrospectively analyzed. Results: None of the renal allografts had primary non-function (PNF) and DGF after transplantation. Four of the 13 recipients with PRA(+)/DSA-had a total of 5 episodes of acute cell-mediated rejection (CMR), while 5 of 8 recipients with pre-existing DSA(+) developed AR, including 3 cases with CMR alone and 2 cases with mixed AR. All episodes of rejection were successfully reversed after targeted treatment. Interestingly, of the 8 recipients with positive preformed DSA, 4 cases with positive DR-DSA and/or class Ⅰ-DSA had their DSA disappeared after transplantation, whereas DQ-DSA remained positive in 4 of 5 recipients. After a median follow-up of 26 months, all recipients maintained normal renal allograft function, and the survival rates of both graft and recipient were 100%. Conclusions: With the use of deceased donors, kidney transplantation can be successfully performed in presensitized patients by appropriate HLA-matching screening, choosing donor kidneys with good quality, and the combination of optimal perioperative treatment.

Abstract
Abstract
Background: Discordance in hormone receptor (HR) status between primary (p) tumors and metastatic (m) recurrences has been widely described. Loss of estrogen and progesterone receptor expression occurs in ˜12% of asynchronous recurrences, leading to triple-negative (TN) status in the metastasis. Genomic mechanisms driving HR loss and its prognostic and therapeutic implications have not been fully elucidated.
Methods: Targeted NGS (Oncopanel, OP) at Dana-Farber Cancer Institute using multiplexed copy number variation and mutation (mut) detection across the full coding regions of 300 genes and selected intronic regions of 35 genes was prospectively performed on either archival primary or metastatic samples collected in patients (pts) with metastatic breast cancer (MBC). Receptor status at initial diagnosis and recurrence were reviewed using a 1% cutoff to define HR-positivity and excluding HER2+ cases. Fisher´s exact test was used to compare frequency of alterations. Tumor mut burden (TMB) was computed normalizing the sum of reported exon mut in each pt by the exonic-bait-set size of the panel.
Results: Between 8/2013-9/2016, 929 pts with MBC underwent OP testing. Of 517 pts diagnosed with primary HR+/HER2- breast cancer, at time of recurrence 388 remained HR+/HER2- (pHR+/mHR+), 39 switched to HR-/HER2- (pHR+/mTN, of which 23 (59%) had initial HR expression >10%), 10 switched to HER2+ and 80 had unknown metastatic receptor status. Comparison between primary samples in pHR+/mHR+ (n=245) and pHR+/mTN (n=24) showed that pHR+/mTN was significantly more likely to harbor mut in TP53, STK11 and MSH6, amplifications (amp) in CCNE1 and FGFR2, and less likely to have PIK3CA mut or CCND1 amp. Median TMB in primary pHR+/mHR+ was 6.05 mut/Mb (0-37.5) and 5.68 mut/Mb (1.2-10.9) in pHR+/mTN (p=0.45). Metastatic samples in pHR+/mTN (n=15) were enriched in ARID1A, CRTC2 and CDH1 mut compared to metastases (n=40) in pts who remained TN (pTN/mTN). Deletions in CDKN2A/2B and RB1, and mut in TP53, NOTCH2 and ERCC2 were more prevalent in recurrent tumors of pHR+/mTN than pHR+/mHR+. In metastases, TMB was higher in pHR+/mTN than pTN/mTN or pHR+/mHR+ (10.9 vs. 7.0 vs. 7.3 mut/Mb, respectively; p=0.002). Median OS from initial diagnosis was 9.4 yrs in pHR+/mTN, less than pHR+/mHR+ (15.9 yrs; p=0.009) and greater than pTN/mTN (4.3 yrs; p=0.008). Median OS from MBC diagnosis was 1.8 yrs in pHR+/mTN, less than pHR+/mHR+ (6.4 yrs; p=0.001) but not significantly different than pTN/mTN (1.5 yrs, p=0.3).

Conclusion: Targeted NGS shows that alterations in DNA damage and cell-cycle regulation pathways in primary HR+ tumors are associated with HR loss in the metastatic setting. Primary tumors that lose HR appear more similar to basal-like than luminal tumors, despite >10% baseline HR expression in most pts, and once metastatic, survival is comparable to pTN/mTN. Metastases with HR loss have higher TMB than those that remain HR+ or TN throughout the course of the disease. These findings, if confirmed, may influence treatment and pt selection for clinical trials.

Abstract
Objective: To investigate if paclitaxel can enhance the protective effect of myocardial ischemia preconditioning on ischemia/reperfusion injury in aged ratand explore related mechanism. Methods: Primary cardiomyocytes of Sprague-Dawley rats were isolated by trypsin and divided into 5 groups(n=6 each): control group, hypoxia injury group, hypoxia preconditioning group, paclitaxel group,and paclitaxel+hypoxia preconditioning group. The structure of microtubules and the expression of hypoxia-inducible factor-1α(HIF-1α) were analyzed by immunofluorescence staining. The Langendorff isolated heart perfusion model was applied in 4 groups: hypoxia reperfusion injury group, hypoxia preconditioning group, paclitaxel group, and paclitaxel+hypoxia preconditioning group. Each group was further divided into elderly subgroup and adult subgroup (n=6 each). Left ventricular developed pressure and maximum rate of rise in left ventricular pressure were analyzed. Results: (1) Primary cardiomyocyte experiments showed that the myocardial tubular microtubule structure in control group was intact and evenly stained; most of the microtubules in the hypoxia-injured group were absent and the tubular tissue was broken; the hypoxia-induced damage on microtubule structure was smaller in the hypoxic preconditioning group compared with the hypoxic injury group (microtubule staining was not uniform, and the lattice structure was broken, but not that obvious as in the hypoxia group); the tubular structure of the microtubules of the paclitaxel group was basically complete, and the staining was basically uniform.The integrity of tubular structure was maintained to some extent, similar to a normal microtubule structure in paclitaxel+hypoxia preconditioning group. The expression of HIF-1α in the cytoplasm and nucleus was very low in the control group, which was evidenced in both cytoplasm and nucleus in the hypoxic injury group.The expression was further increased in hypoxic preconditioning group, significant nuclear HIF-1 expression was found in the paclitaxel group, the expression was aggregated in the nucleus in the Paclitaxel+ hypoxia preconditioning group. (2)In Langendorff isolated heart perfusion model, left ventricular developed pressure was similar between the elderly subgroup and the adult subgroup at the end of the infusion,after precondition, 5 minutes of reperfusion, 30 minutes of reperfusion, and 60 minutes of reperfusion in the hypoxic injury group (all P> 0.05).In the hypoxic injury group, both the elderly subgroup and the adult subgroup had lower left ventricular developed pressure at 30 minutes of reperfusion when compared with the end of the infusion((15.63±4.88) mmHg (1 mmHg=0.133 kPa) vs. (95.63±22.14)mmHg and (17.31±2.75)mmHg vs. (91.00±9.58)mmHg, respectively,all P<0.05). In the hypoxic preconditioning group, the adult subgroup had higher left ventricular developed pressure at 5 and 30 minutes of reperfusion when compared with the elderly subgroup((7.13±1.02) mmHg vs. (3.75±1.06)mmHg and (43.94±3.21)mmHg vs.(16.31±1.54)mmHg, respectively,all P<0.01). In the paclitaxel group, the adult subgroup had higher left ventricular developed pressure at 30 and 60 minutes of reperfusion when compared with the elderly subgroup((44.31±7.59)mmHg vs. (5.44±1.21)mmHg, (51.56±6.03)mmHg vs. (22.19±5.14)mmHg, respectively, all P<0.01). In the paclitaxel+hypoxia preconditioning group, both the elderly subgroup and the adult subgroup had lower left ventricular developed pressure at 30 minutes of reperfusion when compared with the end of the infusion((18.63±4.30)mmHg vs. (99.94±8.23) mmHg, P<0.01; (49.69±5.34)mmHg vs. (95.31±5.26)mmHg, P<0.05). Meanwhile, the adult subgroup had higher left ventricular developed pressure at 30 minutes of reperfusion when compared with the elderly subgroup((49.69±5.34)mmHg vs. (18.63±4.33)mmHg, P<0.01).The adult subgroup had higher change rate of maximum rate of rise in left ventricular pressure at 60 minutes of reperfusion when compared with the elderly subgroup in hypoxia preconditioning group, paclitaxel group, and paclitaxel combined hypoxia preconditioning group((62.83±3.92)% vs. (33.33±3.20)%, (44.17±2.32)% vs. (36.67±2.88)%, (72.50±2.66)% vs. (53.17±2.56)%, respectively,all P<0.01). Conclusion: Paclitaxel can enhance the myocardial protective effect of myocardial ischemia preconditioning through stabilizing microtubules of cardiomyocytes and promoting HIF-1α localization in the nucleus.
