Abstract
Objective: We evaluated the safety and efficacy of lipoprotein apheresis (LA) in patients with familial hypercholesterolemia (FH) who can't reach low-density lipoprotein cholesterol(LDL-C) target goals with the maximal tolerated dose of lipid-lowering agents. Methods: This was a retrospective cross-sectional study. Between February 2015 and November 2019, patients with FH who were admitted in Fuwai hospital and treated with LA were consecutively enrolled. Based on intensive lipid-lowering agents, these patients received LA by double filtration plasma pheresis (DFPP) method. The changes of lipid levels such as LDL-C and lipoprotein(a)[Lp(a)] were compared before and after LA treatment, and the changes of immunoglobulin (Ig) concentration and LA-related adverse effects were also discussed. Results: A total of 115 patients with FH were enrolled in this study, of which 8 cases were homozygous FH and 107 cases were heterozygous FH. The age was (43.9±12.2) years and there were 75 (65.2%) males, and 108 (93.8%) with coronary artery disease. For pre-and immediately after LA treatment, the LDL-C was (5.20±2.94) mmol/L vs. (1.83±1.08) mmol/L, Lp(a) concentration was 428.70(177.00, 829.50)mg/L vs. 148.90(75.90, 317.00) mg/L (P<0.001), with a decrease of 64.2% and 59.8% respectively. The levels of IgG and IgA measured 1 day after LA treatment were both in the normal range and IgM concentration was below the reference value, the reductions of which were 15.1%, 25.0% and 58.7% respectively (P<0.001). Six patients had mild symptoms of nausea, hypotension dyspnea and palpitation, the symptoms were relieved by symptomatic treatment. Conclusion: For patients with FH who do not achieve LDL-C target goal with the maximal tolerated lipid-lowering agents, especially those with elevated Lp(a) levels, LA, which can significantly further reduce LDL-C and Lp(a) levels, is an effective and safe option.

Abstract
Objective: To evaluate the indications, safety, feasibility, and surgical technique for patients with head and neck cancers undergoing transoral robotic retropharyngeal lymph node (RPLN) dissection. Methods: The current study enrolled 12 consecutive head and neck cancer patients (seven males and four females) who underwent transoral robotic RPLN dissection with the da Vinci surgical robotic system at the Sun Yat-sen University Cancer Center from May 2019 to July 2020. Seven patients were diagnosed as nasopharyngeal carcinoma with RPLN metastasis after initial treatments, 4 patients were diagnosed as thyroid carcinoma with RPLN metastasis after initial treatments, and one patient was diagnosed as oropharyngeal carcinoma with RPLN metastasis before initial treatments. The operation procedure and duration time, intraoperative blood loss volume and complications, nasogastric feeding tube dependence, tracheostomy dependence, postoperative complications, and hospitalization time were recorded and analyzed. Results: All patients were successfully treated by transoral robotic dissection of the metastatic RPLNs, none of which was converted to open surgery. RPLNs were completely resected in 10 patients, and partly resected in 2 patients (both were nasopharyngeal carcinoma patients). The mean number of RPLN dissected was 1.7. The operation duration time and intraoperative blood loss volume were (191.3±101.1) min and (150.0±86.6) ml, respectively. There was no severe intraoperative complication such as massive haemorrhage or adjacent organ injury during surgery. Nasogastric tube use was required in all patients with (17.1±10.6) days of dependence, while tracheotomy was performed in 8 patients with (11.6±10.7) days of dependence. The postoperative hospitalization stay was (8.5±5.7) days. Postoperative complications occurred in 4 patients, including 2 of retropharyngeal incision and 2 of dysphagia. During a follow-up of (6.5±5.1) months, disease-free progression was observed in all patients, 10 patients were disease-free survival and other 2 patients were survival with tumor burden. Conclusions: The transoral robotic RPLN dissection is safety and feasible. Compared with the traditional open surgical approach, it is less traumatic and safer, has fewer complications and good clinical application potentiality. The indications for transoral robotic RPLN dissection include thyroid carcinoma, oropharyngeal carcinoma, and some selected nasopharyngeal carcinoma and other head and neck cancers. Metastatic RPLNs from some nasopharyngeal carcinoma with incomplete capsule, unclear border and adhesion to the surrounding vessels are not suitable for transoral robotic RPLN dissection.

Abstract
Objective: To investigate the effect of anatomical hepatectomy and non-anatomic hepatectomy in the treatment of elderly patients with intrahepatic cholangiocarcinoma (IHCC) and their impact on survival outcomes. Methods: In this study, a retrospective method was used to select elderly patients with IHCC who were surgically treated in Shangqiu First People's Hospital from April 2014 to April 2018, and were divided into anatomic resection group and non-anatomical resection group according to the surgical methods they received.The factors affecting the survival outcome of IHCC in the two liver resection methods were analyzed and compared, as well as the effects of liver cirrhosis rate, TNM stage, ascites rate, lymph node metastasis rate, and vascular invasion rate on survival. Results: A total of 181 cases were included in this study, including 87 cases in the anatomical resection group, with 54 males and 33 females, aged (71.4±5.2) years old;There were 94 cases in the non-anatomical resection group, including 49 males and 45 females, aged (70.8±4.8) years.The 3-year survival rate of the anatomical resection group was 41.4% (36/87), which was higher than that of the non-anatomical resection group (25.5% (24/94), the difference was statistically significant (P<0.05);The median survival time of the anatomic resection group was longer than that of the non-anatomical resection group, and the difference was statistically significant P<0.05;The patient's TNM stage was stage III [OR (95%CI): 2.168 (1.245-3.776)], lymph node metastasis [1.664 (1.087-2.545)], and vascular invasion [1.883 (1.167-3.038)] was an independent risk factor for death 3 years after surgery (P<0.05), The patient's anatomical liver resection was a protective factor for the 3-year follow-up survival (P<0.05). Conclusion: The postoperative survival of elderly patients with IHCC is affected by many factors, but anatomic liver resection is beneficial to prolong the survival time of patients.

Abstract
Objective: To study the effect of microRNA-126 (miR-126) on the polarization of human monocyte-derived macrophages stimulated by Porphyromonas gingivalis (Pg) lipopolysaccharide (LPS). Methods: Macrophages derived from human myeloid leukemia mononuclear cells were stimulated by Pg-LPS (5 mg/L) and by Pg-LPS (5 mg/L) after 24 h-transfection of miR-126 mimic or negative control RNA for 48 h, respectively. Real-time quantitative-PCR (qRT-PCR), enzyme-linked immunosorbent assay (ELISA) and Western blotting were conducted to detect the changes in miR-126, pro-inflammatory factor tumor necrosis factor-α (TNF-α), anti-inflammatory factors interleukin-10 (IL-10), inducible nitric oxide synthase (iNOS), arginase-1 (Arg-1) and M1 polarization-related pathways such as nuclear factor kappa-B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways. Results: Compared with non-LPS stimulation group (TNF-α: 1.000±0.020, iNOS: 1.125±0.064, miR-126: 1.004±0.113, IL-10: 1.003±0.053, Arg-1: 1.130±0.061), the mRNA levels of TNF-α (3.105±0.278) and iNOS (4.296±0.003) increased significantly (t=6.53, P=0.003; t=42.63, P<0.001, respectively), while miR-126, IL-10 and Arg-1 expressions (0.451±0.038, 0.545±0.004 and 0.253±0.017) decreased significantly (t=7.95, P=0.001; t=7.36, P=0.002; t=11.94, P<0.001, respectively) after Pg-LPS stimulated by human-derived macrophages for 48 h. The protein expression of iNOS, TNF-α, Arg-1 and IL-10 were consistent at mRNA levels. Meanwhile, the expressions of phospho-NF-κB p65 (p-p65), phospho-extracellular signal-regulated kinase (p-ERK) and phospho-p38 MAPK (p-p38) increased significantly, while the expression of Arg-1 decreased significantly. Compared with the negative controls (scramble RNA) (TNF-α: 1.141±0.197, iNOS: 1.173±0.115, IL-10: 1.032±0.138, Arg-1: 0.933±0.044), the mRNA levels of TNF-α (0.342±0.022) and iNOS (0.588±0.085) expressions significantly decreased (t=5.35, P=0.006; t=5.05, P=0.007), while IL-10 (1.786±0.221) and Arg-1 expressions (2.152±0.229) significantly increased (t=3.71, P=0.021; t=6.21, P=0.003) after Pg-LPS stimulation with miR-126 mimic transfection. The relative protein expressions of iNOS, p-p65, p-ERK and p-p38 significantly decreased (t=13.00, P<0.001; t=6.98, P=0.002; t=10.86, P<0.001; t=8.32, P=0.001), while the protein level of Arg-1 significantly increased (t=12.08, P<0.001). Conclusions: Pg-LPS could promote M1 polarization of macrophages. miR-126 might inhibit the effect of Pg-LPS on the M1 polarization of macrophages through down-regulating NF-κB and MAPK signaling pathways.

Abstract
Objective: To evaluate the characteristics of MRI T2 value changes of muscles around the knee joint in amateur marathon athletes based on T2 mapping. Methods: A total of 12 amateur marathon runners (5 males and 7 females) were recruited as the marathon group, aged from 21 to 37(27.5±5.4) years. MRI examination of bilateral knee joint was performed one week before the race, within 12 hours after the race and two months after the race, respectively. Fifteen healthy volunteers (5 males and 10 females) were recruited as the control group, aged from 24 to 27(24.9±1.0) years, and underwent MRI examination of both knee joints. The T2 mapping imaging sequence was used to measure the T2 values of the sartorius, vastus medialis, biceps femoris, semimembranosus, medial head of gastrocnemius and lateral gastrocnemius head on the post-processing platform, and analyzed the marathon group before and after the race. The differences in the T2 value of each muscle of the marathon group before and after the race within 12 hours, before and 2 months after the race, and between the control group and the marathon group before the marathon were analyzed. Results: All subjects had not knee joint pain during the examination. Routine MRI examination showed that there was no obvious abnormality in the shape and signal of the muscles around the knee joint. The T2 value of the semimembranosus [(34.3±2.8) ms vs (35.5±2.5) ms, P=0.008], medial head of gastrocnemius [(34.1±3.4) ms vs (37.7±3.1) ms,P<0.001] and lateral head of gastrocnemius [(35.2±2.9) ms vs (37.2±3.9) ms,P=0.011] increased after the competition compared with that of pre-competition in the marathon group, while the T2 value of the remaining muscles showed no significant difference compared with that of pre-competition(P>0.05). At the follow-up of 2 months, the T2 value of semimembranosus remains higher than before the marathon [(34.3±2.8) ms vs (35.4±2.5) ms,P=0.043], and the T2 value of the medial head of the gastrocnemius and lateral head of gastrocnemius showed no statistically difference compared with pre-competition (P>0.05). Compared with the control group, the T2 value of the lateral head of the gastrocnemius in the marathon group was decreased [(35.3±3.0) ms vs (38.5±4.1) ms,P=0.007]. There was no significant difference in the T2 value of the remaining muscles in the marathon group (P>0.05). Conclusions: After the marathon, the changes in the T2 value of the muscles around the knee joint is reversible. T2 mapping imaging sequence can indirectly reflect the changes of skeletal muscle microstructure to a certain extent.

Abstract
Background Prurigo nodularis (PN) is a highly pruritic, chronic dermatosis and difficult to treat. PN lesions are characterized by existence of many hyperkeratotic, erosive papules and nodules. However, the pathogenesis of PN still remains unelucidated. Aim To clarify the keratin role in the epidermis hyperproliferation, the keratin expression pattern in the PN lesional skin. Methods In this study, we enrolled 24 patients with PN and 9 healthy control volunteers. K1/K10, K5/K14, K6/K16/K17 expression pattern were investigated by using immunohistochemical staining. Results The lesional skin consists of the thickened spinous layers, in which active cell division was found. K5/K14 were upregulated in PN lesional epidermis, the staining signal localized in the basal layer and lower suprabasal layers. Hyperproliferation‐associated K6 was found in all layers of epidermal lesional skin, especially in the spinous layers. In contrast, K16 was only detected in the basal and lower suprabasal layers, K17 was observed in the basal and spinous layers. Terminal differential keratins K1/K10 were upregulated, detected in the pan‐epidermis, but spared in the basal and low suprabasal layers. Conclusion The keratinocytes enter an alternative differentiation pathway, which are responsible for the activated keratinocyte phenotype, abnormal keratins expression potentially contributes to the keratinocytes proliferation, subsequently lead to increased lesional skin epidermis thickness, hyperkeratiosis and alteration of skin barrier properties.

Abstract
A joint determination of the reactor antineutrino spectra resulting from the fission of ^{235}U and ^{239}Pu has been carried out by the Daya Bay and PROSPECT Collaborations. This Letter reports the level of consistency of ^{235}U spectrum measurements from the two experiments and presents new results from a joint analysis of both data sets. The measurements are found to be consistent. The combined analysis reduces the degeneracy between the dominant ^{235}U and ^{239}Pu isotopes and improves the uncertainty of the ^{235}U spectral shape to about 3%. The ^{235}U and ^{239}Pu antineutrino energy spectra are unfolded from the jointly deconvolved reactor spectra using the Wiener-SVD unfolding method, providing a data-based reference for other reactor antineutrino experiments and other applications. This is the first measurement of the ^{235}U and ^{239}Pu spectra based on the combination of experiments at low- and highly enriched uranium reactors.

Abstract
OBJECTIVES To evaluate the diagnostic efficacy of CBCT-MRI fused image for anterior disc displacement and bone changes of temporomandibular joint (TMJ), which are the main imaging manifestations of temporomandibular disorders (TMD). METHODS Two hundred and thirty-one TMJs of 120 patients who were diagnosed with TMD were selected for the study. The anterior disc displacement, bone defect and bone hyperplasia evaluated by three experts were used as a reference standard. Three residents individually evaluated all the three sets of images, which were CBCT images, MRI images and CBCT-MRI fused images from individual CBCT and MRI images in a random order for the above-mentioned three imaging manifestations with a five-point scale. Each set of images was observed at least 1 week apart. A second evaluation was performed 4 weeks later. Intra- and interobserver agreements were assessed using the intraclass correlation coefficient (ICC). The areas under the ROC curves (AUCs) of the three image sets were compared with a Z test, and p < 0.05 was considered statistically significant. RESULTS One hundred and forty-five cases were determined as anterior disc displacement, 84 cases as bone defect and 40 cases as bone hyperplasia. The intra- and interobserver agreements in the CBCT-MRI fused image set (0.76-0.91) were good to excellent, and the diagnostic accuracy for bone changes was significantly higher than that of MRI image set (p<0.05). CONCLUSIONS CBCT-MRI fused images can display the disc and surrounding bone structures simultaneously and significantly improve the observers' reliability and diagnostic accuracy, especially for inexperienced residents.

Abstract
Malignant pleural mesothelioma (MPM) is a kind of invasive malignant tumor originated from pleural tissue. The incidence of MPM is not high in the population, but the prognosis is very poor. The median survival time is only about 12 months. Pemetrexed combined with platinum is the first-line chemotherapy regimen recommended by the current guidelines. The use of bevacizumab will further prolong the survival of chemotherapy. Once resistance happened, no anti-tumor treatment has been confirmed to achieve survival benefits. Therefore, there is no recommended standard second-line MPM regimen in international and domestic guidelines, including National Comprehensive Cancer Network (NCCN) guidelines. Vinorelbine, gemcitabine and other monotherapy regimens are commonly used in clinical practice, but the median progression free survival (PFS) is only about 3 months. Immune checkpoint inhibitors (ICIS) have been proved to have a significant inhibitory effect on tumor growth in a variety of malignant tumors, and their efficacy is related to the expression of programmed death-ligand 1(PD-L1). In unresectable MPM, programmed death 1 (PD-1)/PD-L1 inhibitors have been used in a series of clinical studies in the first-line, second-line and above treatment. Some of the results have been cited and recommended by international guidelines, but the overall efficacy improvement is still limited. This review summarizes the latest clinical studies and researches in the field of MPM treatment and predicts the directions and prospect of improving the therapeutic effect in the future.

Abstract
Objective: To examine the associations between metabolic syndrome (MS) and the risks for impaired activities of daily living (ADL) in the middle-aged and elderly population in China and provide basis for improving healthy life expectancy. Methods: Prospective cohort study design was used in this study. Based the data of China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2018 and the baseline data in 2011, the follow up for ADL outcomes was conducted in 2013, 2015 and 2018 respectively, and the participants recruited in 2013 and 2015 were new baseline populations. The participants with impaired ADL in three baseline populations were excluded. Cox proportional hazard model was used to estimate the effect of different components and number of MS components on the risk for ADL impairment in the middle-aged and elderly population in China. Results: In 59 795 person-years of follow-up, a total of 1 011 cases of ADL impairments were recorded. The incidence density of ADL impairment was 16.91 per 1 000 person-year; The findings of Cox regression analysis showed that compared with the middle aged and elderly people without MS, the risk for ADL impairments was 1.29 times higher (95%CI: 1.12-1.50) for those with one component of MS, 1.32 times higher (95%CI:1.07-1.64) for those with hyperlipemia complicated with diabetes, 1.78 times higher (95%CI: 1.22-2.59) for those with obesity and one component of MS, 2.48 times higher (95%CI:1.59-3.85) for those with hypertension complicated with hyperlipemia, 3.51 times higher (95%CI:1.66-7.43) for those with hypertension complicated with diabetes, 1.80 times higher (95%CI: 1.40-2.32) for those with ≥3 MS, respectively. Compared with the middle-aged and elderly population without MS, the risk for impaired ADL increased by 30% (HR=1.30, 95%CI: 1.13-1.51), 54% (HR=1.54, 95%CI: 1.28-1.85) and 87% (HR=1.87, 95%CI:1.45-2.41), respectively, in the middle-aged and elderly with one, two, and more than three components of MS, with a significant dose-response relationship that ADL impaired risks increased as the number of MS components increased (P<0.001). Conclusions: Our findings suggested that MS is a risk factor for ADL impairment in middle-aged and elderly population in China. Prevention and early intervention of obesity, hypertension, hyperlipemia, diabetes and metabolic syndrome could help to reduce or delay the incidence of ADL impairment.

Abstract
As carriers containing abundant biological information, exosomes could deliver the property of donor cells to recipient cells. Emerging studies have shown that tumor cells could secrete a mass of exosomes into the microenvironment to regulate bystander cells. However, the underlying mechanisms of such a phenomenon remain largely unexplored. In this research, we purified and identified the exosomes of A549 cells and found that A549-cell-derived exosomes promoted BEAS-2B cells migration, invasion, and epithelial-mesenchymal transition (EMT). Importantly, we observed that let-7c-5p and miR-181b-5p were attenuated in A549-cell-derived exosomes compared to BEAS-2B-cell-derived exosomes. The analysis of miRNA expression level in BEAS-2B cells indicated that incubation with A549-cell-derived exosomes reduced the expression levels of let-7c-5p and miR-181b-5p. In transient transfections assay, we found that downregulation of let-7c-5p and miR-181b-5p simultaneously showed stronger promotion of BEAS-2B cells migration and invasion than individually. Moreover, exosomes secreted from A549 cells with upregulated expression of let-7c-5p and miR-181b-5p significantly reduce their regulatory effect on BEAS-2B cells. Bioinformatics analyses revealed that let-7c-5p and miR-181b-5p inhibit the EMT process mainly by regulating focal adhesion and mitogen-activated protein kinase (MAPK) signaling pathway. Thus, our data demonstrated that A549-cell-derived exosomal let-7c-5p and miR-181b-5p could induce migration, invasion, and EMT in BEAS-2B cells, which might be regulated through focal adhesion and MAPK signaling pathway. The expression level of let-7c-5p and miR-181b-5p may show great significance for the early diagnosis of lung cancer.

Abstract
This study focused on the removal of organic matter and nitrogen and explored the feasible operation strategies to achieve short-cut nitrification and denitrification in two constructed wetlands (CWs), which were designed to treat the actual landfill leachate from a small county in parallel. The two CWs were horizontal sub-surface flow constructed wetlands (HFCW) with partial-area aeration and vertical sub-surface flow constructed wetlands (VFCW) with full-area aeration. The experimental results showed that both CWs could achieve an excellent organic matter and nitrogen removal performance under the conditions of intermittent aeration with high frequency and medium intensity (2 h of aeration and 4 h of rest). The removal efficiencies of COD and total nitrogen by HFCW were 89.08% and 73.22%, and the corresponding values of VFCW were 84.51% and 71.44%, respectively. Meanwhile, the inhibition kinetics model indicated that HFCW with partial-area aeration could enhance the free ammonium (FA) tolerance of ammonium-oxidizing bacteria (AOB) and reduce the conversion percentage of ammonia nitrogen. In addition, the intermittent aeration mode with high frequency and medium intensity could keep the DO concentration below under 0.60 mg L-1 in HFCW, which helped to achieve stable short-cut nitrification and ensure the average nitrite accumulation rate (NAR) reach 50.96%. These results suggested that the intermittent aeration in partial-area could achieve successful short-cut nitrification in HFCW, thereby improving the removal efficiency of nitrogen in landfill leachate.

Abstract
Abstract
Background
Although several previous studies indicated that the existence of physical signs [tendon xanthomas or corneal arcus (TX/CA)] was associated with the risk of coronary artery disease (CAD) in patients with heterozygous familial hypercholesterolemia (HeFH), its relations to genotypes and clinical characteristics have not been fully determined. The present study aims to examine the association of TX/CA with genetic mutation, lipid and inflammation-related markers, coronary calcification, coronary severity and cardiovascular events (CVE) in Chinese patients with HeFH.
Methods
A total of 489 HeFH patients diagnosed with Dutch Lipid Clinic Network (DLCN) criteria and/or genetic testing were consecutively recruited. To compare the patients with TX/CA versus those without, propensity score matching (1:4 matched) was performed to adjust for age and sex. Patients were finally divided into the TX/CA group (n=50) and non-TA/CA group (n=200). Data including genetic mutation [low-density lipoprotein receptor (LDLR), apolipoprotein B (APOB), and proprotein convertase subtilisin/kexin type 9 (PCSK9)] and laboratory analysis including lipoprotein(a), PCSK9, high-sensitivity C-reactive protein (hsCRP), computed tomography angiography, coronary angiography, and follow up CVEs were compared.
Results
Patients with physical signs presented significantly higher LDL cholesterol levels (8.65±2.53 vs. 7.70±2.18 mmol/L, p=0.025), more LDLR (+) mutations (OR 2.896, 95% CI 1.295–6.473, p=0.010), higher prevalence of high tertiles of Gensini, SYNTAX and Jeopardy score, and coronary artery calcium scores compared to those without. In addition, patients in the TX/CA group had a higher prevalence of high PCSK9 and hsCRP tertiles compared with those without signs. Over an average of 3.7 years of follow-up, patients with TX/CA were at a significantly greater risk of CVE (multivariate adjusted hazard ratio [HR] 2.81, 95% confidence interval [CI] 1.14–6.90, p=0.024).
Conclusions
The physical signs were associated with positive genetic mutation, higher PCSK9 or hsCRP concentration and worse outcomes in patients with HeFH, suggesting that these signs may help to risk stratification in patients with HeFH.

Abstract
Abstract
Aims
Type 2 diabetes mellitus (T2DM) is an independent risk factor for cardiovascular disease. However, the association between T2DM and coronary artery disease (CAD) in patients with heterozygous familial hypercholesterolemia (HeFH) has not been thoroughly evaluated. Our study aimed to assess the effect of T2DM on CAD severity and hard cardiovascular endpoints in a HeFH cohort.
Methods
A total of 432 patients with HeFH with a molecular and/or clinical Dutch Lipid Clinic Network score ≥6 (definite and probable) were enrolled. Patients were divided into a T2DM group (n=99) and a non-T2DM group (n=333). Hard endpoints included a composite of non-fatal myocardial infarction, stroke, and cardiac death.
Results
No differences were observed regarding genetic mutations in patients with and without T2DM. Patients with T2DM demonstrated a greater number of diseased vessels (p=0.029) and more severe coronary lesions with high Gensini, SYNTAX, and Jeopardy score tertiles. Compared with patients without T2DM, patients with T2DM were at a significantly greater risk of hard endpoints (multivariate adjusted hazard ratio [HR] 2.32, 95% confidence interval [CI] 1.02–4.84, p=0.025). Additionally, patients with T2DM and good glucose control (HbA1c <7.0%) were at a lower risk of hard endpoints compared with those with poor glucose control (HbA1c ≥7.0%, HR 0.08, 95% CI 0.01–0.56, p=0.011).
Conclusions
We conclude that T2DM is an independent predictor of CAD severity when assessed by four different tests and worse cardiovascular outcomes, suggesting that T2DM could be further used for risk stratification of patients with HeFH.

Abstract
Objective: To investigate the adverse childhood experience (ACE) effects on the risk of chronic diseases among middle-aged and elderly. Methods: A retrospective cohort study was conducted using the China Health and Retirement Longitudinal Study data. We used life history study data in 2014 as baseline data and data of chronic diseases of middle-aged and elderly in 2015 as outcomes. A zero-inflated negative-binominal model was used to estimate the incidence rate ratio (IRR) for the association between ACE and chronic diseases. Results: Compared with the less than 4 points of ACE exposure in childhood, individuals with ACE exposure 4-, 6- and ≥9 were associated an increased risk of chronic disease, adjusted IRR (95%CI), 1.10(1.04-1.16), 1.18 (1.13-1.25), 1.34 (1.27-1.42), respectively, with a significant dose-response relationship that chronic diseases risks increase parallel with the increase of ACE exposure. Conclusions: ACE might serve as one of the critical risk factors of chronic diseases in middle-aged elderly. It's of public health significance for early screening and intervention of ACE, reducing the incidence of chronic diseases, and improving middle-aged and older adults' quality of life and health.

Abstract
To understand the relationships among dominant species of cephalopods in offshore nor-thern South China Sea, we examined the niche characteristics of these dominant species from both spatial and temporal dimensions using the index of relative importance (IRI), the niche breadth and overlap indices based on fishery resources data from the bottom-trawl survey for four seasons during 2014-2015. The results showed that five dominant species of cephalopods were recorded for four seasons, including Loligo edulis, L. chinensis, L. beka, Sepia esculenta, and L. duvaucelii. The first two species were shared by all seasons. Compared with historical data, the composition of dominant cephalopods species had changed. The cephalopods resource exhibited obvious temporal and spatial variations. Stock density was higher in the sea area extending from the southern Hainan Island to eastern Guangdong Province than that in Beibu Gulf. The seasonal variation was characte-rized by the largest in summer but the smallest in winter. The temporal and spatial niche analysis showed that there was inconsistent in the order between temporal and spatial niche breadths for domi-nant species. L. edulis (1.32) and L. chinensis (3.90) occupied the largest temporal and spatial niche breadths, respectively. The smallest of temporal and spatial niche breadths were shown for S. esculenta (0.98) and L. duvaucelii (2.04), respectively. Though the temporal niche overlap was numerically larger than the spatial niche overlap, both of them had higher values in interspecies among L. edulis, L. chinensis, L. beka, and the lower overlap for the species pairs between L. duvaucelii and other species. The result of correlation analysis suggested that niche breadth exhibited a significant negative correlation with variation in abundance on both temporal and spatial scales. The ecological niche could reflect the tempo-spatial changes of species resource, which enriched the traditional methods of fishery communities.

Abstract
PURPOSE Papillary thyroid carcinoma (PTC) represents the most common subtype of thyroid cancer (TC). This study was set out to explore the potential effect of CHD1L on PTC and type 2 diabetes mellitus (T2DM). METHODS We searched for T2DM susceptibility genes through the GWAS database and obtained T2DM-related differentially expressed gene from the GEO database. The expression and clinical data of TC and normal samples were collated from the TCGA database. Receiver operating characteristic (ROC) curve analysis was subsequently applied to assess the sensitivity and specificity of the CHD1L for the diagnosis of PTC. The MCP-counter package in R language was then utilized to generate immune cell score to evaluate the relationship between CHD1L expression and immune cells. Then, we performed functional enrichment analysis of co-expressed genes and DEGs to determine significantly enriched GO terms and KEGG to predict the potential functions of CHD1L in PTC samples and T2DM adipose tissue. RESULTS From two genes (ABCB9, CHD1L) were identified to be DEGs (p < 1 * 10-5) that exerted effects on survival (HR > 1, p < 0.05) in PTC and served as T2DM susceptibility genes. The gene expression matrix-based scoring of immunocytes suggested that PTC samples with high and low CHD1L expression presented with significant differences in the tumor microenvironment (TME). The enrichment analysis of CHD1L co-expressed genes and DEGs suggested that CHD1L was involved in multiple pathways to regulate the development of PTC. Among them, Kaposi sarcoma-associated herpesvirus infection, salmonella infection and TNF signaling pathways were highlighted as the three most relevant pathways. GSEA analysis, employed to analyze the genome dataset of PTC samples and T2DM adipose tissue presenting with high and low expression groups of CHD1L, suggests that these differential genes are related to chemokine signaling pathway, leukocyte transendothelial migration and TCELL receptor signaling pathway. CONCLUSION CHD1L may potentially serve as an early diagnostic biomarker for PTC, and a target of immunotherapy for PTC and T2DM.

Abstract
Objective: To evaluate the effect of transfusion-free techniques on the prognosis of liver transplant patients. Methods: The recipients of adult liver transplantation at Tianjin First Central Hospital from August to December 2019 were included in the clinical observation. Liver transplantation without allogeneic blood transfusion was performed through anesthesia management techniques such as acute hemodilution or phlebotomy without volume replacement,maintaining decreased baseline central venous pressure and cell saver. According to the actual results,the patients were divided into two groups: transfusion-free group(n=21) and allogeneic transfusion group(n=28). There were 13 males and 8 females aged of (56.3±11.6) years in the transfusion-free group;and there were 16 males and 12 females aged (54.3±14.2)years in the allogeneic transfusion group. The transplant recipients who had not adopted transfusion management strategy from January to July 2019 were included as control group(27 males and 13 females,aged of (58.9±14.1)years). The clinical data of patients in perioperative period were collected to compare whether there were differences in the recovery of liver function and early complications among the three groups, one-way ANOVA test, rank-sum test, and χ2 test were used for data analysis. Results: The amount of intraoperative blood loss in both the transfusion-free group and the transfusion group was less than that in the control group((454.2±271.3)ml vs.(673.6±333.4)ml vs.(890.3±346.7)ml;q=-6.342,-5.286,both P<0.05).The duration of stay in ICU of the transfusion-free group was less than that of the transfusion group and control group((36.4±9.1)hours vs.(44.3±14.9)hours vs.(58.2±21.1)hours;q=-4.432,-3.824,both P<0.05).The mean ALT level at 7 days after operation was significantly lower in the transfusion-free group than in the control group((56.8±32.1)U/L vs.(89.6±45.6)U/L;q=-3.358,P<0.05). Conclusions: The improvement of multi-disciplinary transfusion management technology aimed at transfusion-free liver transplantation can effectively reduce intraoperative hemorrhage and help to avoid surgical transfusion. Transfusion-free liver transplantation is beneficial to the early postoperative recovery,and its long-term clinical significance is worthy of further clinical research.

Abstract
Neoadjuvant chemotherapy (NACT) is a vital part of the systemic treatment to breast cancer. With the formation of consensuses on NACT, controversial perspectives on NACT have been widely discussed, especially in the fields of indication and therapeutic strategy. To define the indication of NACT, blind obedience to the results of clinical trials is not recommended. Instead, indications of NACT should be strictly controlled based on the targets of the clinical practice. Oriented by the early effectiveness of NACT, various chemotherapy or local therapeutics for different molecular subtypes of breast cancer should be conducted to the patients with unsatisfied effect. What's more, the evolvement of precision medicine accelerates the research of drugs and helps to form an individualized NACT plan. After clarifying the controversial opinions towards NACT in breast cancer, controlling the indication and optimizing the therapeutic strategy will improve the survival of breast cancer patients.

Abstract
Objective: To investigate the repair of subepithelial nerve fibers in different areas of the cornea and the difference of corneal transparency 12 months after small incision lenticule extraction (SMILE), femtosecond laser in situ keratomileusis (FS-LASIK) and excimer laser in situ keratomileusis (LASEK) in high myopia. Methods: A cohort study. From June 2018 to October 2019, 30 patients with high myopia (60 eyes) were selected for corneal refractive surgery in the Department of Ophthalmology, Affiliated Hospital of Qingdao University, including 16 females (32 eyes) and 14 males (28 eyes). According to the mode of operation, the patients were divided into the SMILE group (n=10), FS-LASIK group (n=11) and LASEK group (n=9). The repair of subepithelial nerves in different areas of the cornea was observed by laser confocal microscopy 12 months after operation,and the morphological parameters were analyzed by ACCMetrics software. The parameters included corneal nerve fiber density (CNFD), corneal nerve branch density (CNBD), corneal nerve fiber length (CNFL), corneal nerve fiber total branch density (CTBD) and corneal nerve fiber width. The Pentacam anterior segment analyzer was used to measure the optical density of the cornea in different diameters. The nerve fiber parameters and corneal optical density were compared by random block analysis of variance, and multiple comparisons were performed between groups by the Turkey test. Results: Twelve months after operation, there was no significant difference in the CNFD among the three groups(all P>0.05). The CNBD around the upper corneal incision in the SMILE group, FS-LASIK group and LASEK group was (7.81±7.93), (9.61±7.18) and (21.25±15.55) branches/mm2, respectively. The CTBD was (22.00±16.02), (24.44±11.42) and (54.37±22.13) branches/mm2, respectively. The values in the LASEK group significantly differed from the other two groups (HSD=2.823, -3.010, 3.053, -3.048, P<0.01). The CNFL was (9.19±3.25), (12.88±3.52) and (15.75±2.36) mm/mm2, respectively. The value in the SMILE group was significantly different (HSD=-3.151, -4.418; P<0.0l). The corneal optical density after SMILE was 13.16±0.72 in the 0-6 mm diameter area(HSD=-4.164, -4.489; P<0.01), 16.12±3.18 in the 6-12 mm diameter area(HSD=-3.918, -3.493;P<0.01) and 14.06±1.36 in the total diameter (HSD=-6.031, -5.519;P<0.01), which differed significantly from the other two groups. Conclusions: Twelve months after SMILE for high myopia, the nerve repair around the superior corneal incision is slightly worse than that after FS-LASIK and LASEK, but the nerve repair in other areas has some advantages, and the corneal transparency is better.
