Abstract
Objective: To investigate the influence of HBV infection on the prevalence of fatty liver disease in Jinchang cohort and provide theoretical evidence for the prevention and treatment of fatty liver disease. Methods: Epidemiological investigation, laboratory examination and abdominal ultrasound were conducted in the baseline population of Jinchang cohort to collect the basic data, the differences in the prevalence of fatty liver disease under different HBV infection patterns were described and compared and the influence of different HBV infection patterns on the prevalence of fatty liver disease were evaluated by using logistic regression analysis. Results: The baseline Jinchang cohort population totaled 45 605, including 27 917 males and 17 688 females. The male to female ratio was 1.6∶1. The mean age of the overall population was 46.49 years. Among the 8 common HBV infection modes in the Jinchang cohort, the prevalence of fatty liver was low in HBsAg, HBeAg and HBcAb positive, HBsAg and HBcAb positive, and HBsAg, HBeAb and HBcAb positive groups. For 4 serum markers of HBV infection, the prevalence of fatty liver disease in HBsAg and HBeAg positive groups was lower than that in HBsAg and HBeAg negative groups. Logistic regression analysis showed that being HBsAg and HBcAb positive (OR=0.61, 95%CI: 0.39-0.98) and HBsAg, HBeAg and HBcAb positive (OR=0.52, 95%CI: 0.30-0.89) could reduce the risk for fatty liver disease. Conclusion: Acute HBV infection reduces the prevalence of fatty liver disease, and the reason may be related to the disturbance of the body's fat metabolism by active HBV replication.

Abstract
Objective: To explore the influencing factors for non-alcoholic fatty liver disease (NAFLD) in Jinchang cohort, and provide scientific basis for the prevention and control of NAFLD. Methods: A total of 20 051 patients without fatty liver at baseline survey and met the inclusion criteria in Jinchang cohort were selected as study subjects. Prospective cohort study and Cox regression analysis were used to investigate the influencing factors for NAFLD, and the dose-response relationship between related biochemical indicators and NAFLD risk was studied by restricted cubic spline method. Results: The incidence of NAFLD was 42.37/1 000 person years. Multivariate Cox regression analysis showed that being worker and technical personnel (being worker:HR=0.84,95%CI:0.70-0.99;being technical personnel:HR=0.73,95%CI:0.56-0.95), tea drinking (current drinking:HR=0.86,95%CI:0.78-0.94;previous drinking: HR=0.52,95%CI: 0.31-0.86), exercise (occasionally: HR=0.79, 95%CI: 0.68-0.91;frequently:HR=0.60,95%CI:0.52-0.69), low body weight (HR=0.10, 95%CI: 0.05-0.22), daily intake of dairy products >300 ml/day (HR=0.78, 95%CI: 0.71-0.87) and HBV infection (HR=0.77, 95%CI: 0.60-0.99) were the protective factors for NAFLD, while being internal or office workers (HR=1.84, 95%CI: 1.46-2.31), income ≥2 000 yuan (2 000- yuan: HR=1.32, 95%CI: 1.04-1.66; ≥5 000 yuan: HR=1.72, 95%CI:1.11-2.66), bachelor degree or above (HR=1.35,95%CI:1.03-1.76), overweight (HR=2.31, 95%CI:2.08-2.55), obesity (HR=3.95, 95%CI: 3.42-4.56), impaired fasting blood glucose (HR=1.31, 95%CI:1.17-1.47), diabetes (HR=1.53, 95%CI: 1.30-1.80), increased TC (HR=1.37,95%CI:1.24-1.52), increased TG (HR=1.79,95%CI: 1.62-1.98), decreased HDL-C (HR=1.29, 95%CI: 1.14-1.45), increased ALT (HR=1.13, 95%CI: 1.01-1.26) and high-fat diet (HR=1.24, 95%CI: 1.11-1.40) were the risk factors for NAFLD. Moreover, TC, TG, HDL-C, ALT and FPG all showed good dose-response relationship with the incidence of NAFLD. Conclusion: Occupation, education level, income level, tea drinking, exercise, BMI, FPG, blood lipid, ALT, HBV infection and diet were related to the incidence of NAFLD.

Abstract
BACKGROUND Lung cancer is one of the most aggressive malignancies and the efficacy of chemotherapy or concurrent chemoradiation is limited in clinical application. Curcumin has been reported to block cancer development by modulating multiple signaling pathways. However, whether curcumin can inhibit gemcitabine-resistant non-small cell lung cancer through regulation of lncRNA and the involved molecular mechanisms are rarely reported. MATERIALS AND METHODS MTT assay, clonogenic assay, apoptosis assay, qRT-PCR, Western blotting, immunohistochemistry, xenograft experiment were carried out in the present study. RESULTS The results showed that curcumin suppressed gemcitabine-resistant non-small cell lung cancer cell proliferation and induced apoptosis. Curcumin upregulated the expression of lncRNA-MEG3 and PTEN, and MEG3 overexpression could increase the level of PTEN expression, while MEG3 knockdown decreased the level of PTEN expression in gemcitabine-resistant non-small cell lung cancer cells. Curcumin treatment failed to inhibit the proliferation and induce apoptosis in MEG3 knockdown or PTEN knockdown cells. CONCLUSIONS These findings show the antitumor activity of curcumin for potential clinical application in gemcitabine-resistant non-small cell lung cancer treatment.

Abstract
This study aimed to evaluate the effectiveness and long-term outcomes of free and pedicled, expanded deltopectoral flaps with perforation of the internal thoracic artery to repair facial scars. This retrospective review was of 37 patients who presented between June 2013 and June 2019 with various types of facial scar. Ten patients received a free expanded deltopectoral flap and 27 a pedicled, expanded deltopectoral flap. During the stage-one operation, the expander was implanted into the deltopectoral area and fully expanded by normal saline injection. In stage two, the facial lesions were incised, and the free or pedicled flap transferred to reconstruct the defect. Flap necrosis did not occur in the 10 patients treated with free flaps. Two patients need to have the pedicle trimmed three months after surgery because it had become bloated. Distal necrosis occurred in five of 27 patients who received a pedicled, expanded deltopectoral flap. Healing by conservative treatment was noted in two cases and healing after skin grafting was documented in the other three. All 37 patients achieved satisfactory results. A pedicled, expanded deltopectoral flap appears to be a reliable and safe option for the treatment of facial scars.

Abstract
Objective: During the COVID-19 pandemic, the electronic "questionnaire star" was employed to investigate the general situation, medication situation and pandemic impact of children diagnosed with asthma in our hospital and enrolled in the electronic platform of the Chinese Children's Asthma Action Plan (CCAAP). The internet technology and big data were used to grasp the trend and asthma control of children who had been at home for a long time due to the pandemic, so as to facilitate the management. Methods: By random cluster sampling survey method, according to the needs and medication adherence score, the electronic "questionnaire star" was designed to conduct a survey among children (0 to 14 years old) who diagnosed with asthma and joined the CCAAP on the basis of bronchial asthma medication adherence scale. Finally, the results of electronic questionnaire survey were analyzed. Results: A total of 423 questionnaires were sent out, 422 of which were valid, with an effective response rate of 99.7%. The results of questionnaire survey showed that 296 cases were male, accounting for 70.1%, and 126 cases were female, accounting for 29.9%, with an average age of (5.4±2.6) years old. The average age of males and females was (5.3±2.6) and (5.4±2.6) years old, respectively. There were more children aged ≥5 years than children who were younger than 5 years. Additionally, 13.95% of the parents thought that the pandemic had more than moderate impact on children with asthma, and 76.12% of the children were in the green zone and had no asthma attack. The proportion of green zone inhaled drugs (79.8%) was higher than yellow zone and red zone (49.8%). After using the CCAAP platform, the dissatisfaction rate was only 1.42%. Moreover, 71.87% of the children's medical expenses decreased, and the proportion of frequent use and intermittent use of antibiotics reduced, however, the proportion of occasional use and never use of antibiotics increased significantly (all P<0.05). The average score of drug compliance was 4.56, and the more frequently the platform was used, the higher the score of medication compliance was (P<0.05). Conclusions: After using CCAAP management with the aid of internet technology, children with asthma who had been isolated at home for a long time were less affected by COVID-19, with high medication compliance, generally lower medical expenses, significantly reduced use of antibiotics, and high satisfaction. This management mode provides a new idea for internet medicine.

Abstract
OBJECTIVE To illustrate the role of FOXF2 in the aggravation of the progression of non-small cell lung cancer (NSCLC) by targeting long non-coding RNA (lncRNA) H19 to down-regulate the gene of phosphate and tensin homolog deleted on chromosome ten (PTEN). PATIENTS AND METHODS The relative levels of FOXF2 and H19 in NSCLC tissues and adjacent normal tissues were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlation between the expression levels of FOXF2 and H19 was analyzed. Kaplan-Meier curves were depicted for uncovering the prognostic value of FOXF2 in NSCLC patients. The proliferative and migratory abilities of A549 cells influenced by FOXF2 were also assessed. The interaction between FOXF2 and H19 was evaluated through chromatin immunoprecipitation (ChIP) assay and Western blot, so did the association between H19 and PTEN. Finally, rescue experiments were conducted to explore the role of FOXF2/H19/PTEN axis in regulating the viability and migration of A549 cells. RESULTS FOXF2 and H19 were upregulated in NSCLC and a positive correlation was observed between the two genes. High level of FOXF2 indicated a worse prognosis in NSCLC patients. The knockdown of FOXF2 attenuated the proliferative and migratory abilities of A549 cells. FOXF2 could bind to the promoter region of H19 and accelerated its transcription. Moreover, H19 could recruit EZH2 to bind to PTEN. The overexpression of H19 could reverse the regulatory effects of FOXF2 on the viability and migration of A549 cells. CONCLUSIONS FOXF2 was upregulated in NSCLC. It accelerated the proliferative and migratory abilities of the NSCLC cells by targeting H19 to downregulate PTEN, thus aggravating the progression of NSCLC.

Methods: Using cluster sampling method, 603 medical staff with occupational exposure with blood-borne pathogens were analyzed, from July 2014 to July 2018 in a tertiary hospital. Results: In total of 603 occupational exposure incidents, 70.98% (428/603) were freshmen younger than 30 years old. 48.92% (295/603) nurses. The most cases of occupational exposure were in surgery (35.16%, 212/603) . Sharp injury was the major contact manner (86.90%, 524/603) . Hands were the main contact parts (90.38%, 545/603) . Ward (53.57%, 323/603) and the operating room (22.72%, 137/603) were the high-risk place. The most dangerous actions were needle injection (34.83%, 210/603) , surgery (20.89%, 126/603) and finishing/cleaning items (19.73%, 119/603) . The main items lead to injuries were scalp needles (34.73%, 182/524) . The most exposure source was hepatitis B virus (HBV) which occupied 39.30% (237/603) . Exposure source mainly comes from medical devices containing blood (81.92%, 494/603) . To compared the groups (χ(2)=19.940, P<0.01) and titer (t=-8.592, P<0.01) of hepatitis B surface antibody (HBsAb) before and after used prophylactics, the differences were statistically significant. Conclusion: Comprehensive strategies of occupational exposure protection education, operation norms and monitoring management were effective methods to reduce the occupational exposure in the medical staff with blood-borne pathogens.

Abstract
Objective: To investigate the clinical value of extended radical resection for stage pT3 gallbladder cancer (GBC). Methods: The clinical and pathological data of 323 patients with stage pT3 GBC who received regional radical resection or extended radical resection in 7 domestic hepatobiliary centers in China from January 2013 to December 2018 were retrospectively analyzed. The propensity score matching method was used to select 36 cases in each of the regional radical resection group (group A1) and the extended radical resection group (group B1). The surgical indicators and overall survival rates of the two groups were compared, and prognostic factors were analyzed. Results: The number of positive lymph nodes [2(0,3)] and the total number of lymph nodes removed [3(1,4)] in group B1 were both higher than those in group A1 [1(0,1), 4(2,7)] (all P<0.05). There was no significant difference in other clinical and pathological factors between the two groups (all P>0.05). The 1, 3, and 5-year survival rates of group A1 were 75%, 44%, and 29%, respectively, which were significantly higher than those of group B1 of 50%, 15%, and 11% (χ(2)=11.311, all P<0.001). Extensive radical resection (HR=2.161, 95%CI: 1.222-3.821), hepatic parenchymal invasion (HR=2.324, 95%CI: 1.305-4.139), positive lymph node rate ≥1/3 (HR=2.927, 95%CI: 1.641-5.220), and ⅢB/ⅣB staging (HR=3.325, 95%CI: 1.750-6.320) are risk factors for the prognosis of GBC patients (all P<0.05), of which extended radical resection (HR=1.969, 95%CI: 1.083-3.581) was an independent risk factor for prognosis (P<0.05). When the ratio of positive lymph nodes was<1/3 and the tumor invaded the hepatic parenchyma, the overall survival rate of group B1 was significantly lower than that of group A1 (all P<0.05). Conclusions: The overall survival rate in patients with stage pT3 GBC whose lymph node positive rate<1/3 and/or hepatic parenchymal invaded cannot be improved by extended radical resection. Extended radical resection is an independent risk factor for patient prognosis.

Abstract
Al alloys have widespread industrial applications. However, their mechanical strength is often much lower than steels. Here, we investigate the influence of solutes on achieving ultrahigh strength and thermal stability of nanotwinned Al alloys. In situ micropillar compression tests show the addition of a small amount of Ti can significantly increase the mechanical strength of Al-Ni alloys to 2 GPa. Deformation induced detwinning, Ni segregation and grain coarsening as discovered in binary Al-Ni alloys are mostly absent in the ternary Al-Ni-Ti alloys. Moreover, the ternary Al-Ni-Ti alloys have outstanding thermal stability. Density function theory calculations reveal the synergetic pinning effect of Ni-Ti solute pairs on incoherent twin boundaries. This study demonstrates that the proper selection of synergistic solute pairs is critical to improve the thermal stability and mechanical properties of nanotwinned Al alloys.

Abstract
OBJECTIVE Metastasis is one of the main causes of leading recurrence and death in patients with hepatocellular carcinoma (HCC). XRCC5 can affect several types of human cancers. The aim of the present study is to explore the metastasis correlation between the expression level of XRCC5 protein in HCC cell lines with different metastatic potentials and the prognosis of patients with HCC. MATERIALS AND METHODS Hepatocellular carcinoma cell lines used in this study include MHCC97-H, MHCC97-L, HepG2, and HL-7702. RESULTS XRCC5 was widely expressed in HCC cell lines analyzed by Real-Time Reverse Transcription PCR and Western blotting. The levels of XRCC5 protein and mRNA were positively correlated with the migration and invasion capability of HCC cell lines. SiRNA-XRCC5 significantly suppressed the migration and invasion of HCC cells. Immunohistochemistry (IHC) results showed that high-expressed XRCC5 in patients with HCC was associated with advanced tumors, size, and microvascular invasion and lower overall survival time than the low-expressed. The expression levels of CTNNB1 and MMP9 decreased by knocked down XRCC5 which may promote the progression of HCC via the Wnt/β-catenin signaling pathway. CONCLUSIONS Our results suggest that the high expression of XRCC5 predicts poor prognosis in patients with HCC, and XRCC5 may be a potential biomarker to inhibit the invasion and migration of HCC.

Abstract
Objective: To investigate the expression status and diagnostic value of SRY related high mobility group box 11 (SOX-11) and transcription factor E-3 (TFE3) in solid pseudopapillary tumors of pancreas (SPTPs). Methods: Thirty-eight cases of SPTPs, 36 cases of well-differentiated pancreatic neuroendocrine tumors (PanNETs) and six cases of pancreatic acinar cell carcinomas (PACCs) were collected at the Affiliated Drum Tower Hospital of Nanjing University Medical School from 2012 to 2019. The expression of SOX-11, TFE3 and β-catenin was detected by immunohistochemistry, and the TFE3 gene status was detected by FISH in 18 cases of SPTPs. Results: Among the 38 SPTP patients, 29 were female and 9 were male, with a mean age of 50 years; among 36 PanNET patients, 32 were female and 4 were male, with a mean age of 39 years; for the six PACC patients, four were male and two were female, with a mean age of 60 years. β-catenin was positive in all 38 SPTPs, but was negative in all 36 PanNETs and 5/6 PACCs. SOX-11 was positive in 35/38 (92.1%) of SPTPs, but was negative in all 36 PanNETs and 6 PACCs. TFE3 was positive in 36/38 (94.7%) of SPTPs, but was negative in all 36 PanNETs and 6 PACCs. Among these three tumors, the specificity and sensitivity of β-catenin were 97.6% and 100.0%, the specificity and sensitivity of SOX-11 were 92.1% and 100.0%, the specificity and sensitivity of TFE3 were 94.7% and 100.0%, respectively. There was a significant difference of the expression status of all three markers in SPTPs compared with PanNETs and PACCs (P<0.01). The results of SOX-11 and TFE3 immunostaining showed high consistency (Kappa>0.6). No gene rearrangement (0/18) of TFE3 was found in SPTPs. Conclusion: SOX-11 and TFE3 are highly expressed in SPTPs, and their specificity in the differential diagnosis of SPTPs is better than that of β-catenin.

Abstract
OBJECTIVE This study aims to explore the potential functions of miR-137-5p and interleukin-10R1 (IL-10R1) in mediating the immune inflammation after spinal cord injury (SCI). MATERIALS AND METHODS Firstly, primary microglia were isolated from the spinal cord of newborn rats. Expression levels of miR-137-5p and IL-10R1 in LPS-induced microglia were determined by quantitative Real-time polymerase chain reaction (qRT-PCR). In addition, mRNA expressions of Janus kinase (Jak1) and signal transducer and activator of transcription 3 (STAT3) were also examined by qRT-PCR. SCI model in rats was established and randomly assigned to three different groups: Sham group, SCI group and miR-137-5p mimic group. Within one week of spinal injury, relative levels of miR-137-5p and IL-10R1 in rats of different groups were detected by qRT-PCR. The mRNA levels of JAK1, tyrosine kinase (Tyk2) and STAT3 in rats were also measured. Moreover, protein expression of IL-1β, TNF-α and IL-6 in rats was measured by Western blotting. Finally, the improvement of locomotor function in three groups of rats within 4 weeks via BBB rating scale. RESULTS Transfection of miR-137-5p mimics upregulated relative levels of IL-10R1, JAK1 and STAT3 in in vitro cultured microglia. Similarly, IL-10R1/JAK1/STAT3 pathway was activated in rats administrated with miR-137-5p mimics. Nevertheless, relative levels of classical inflammatory stimulators IL-1β, TNF-α and IL-6 were downregulated accordingly by miR-137-5p overexpression. Moreover, miR-137-5p effectively improved the locomotor function of rats after SCI. CONCLUSIONS MiR-137-5p exerts an anti-inflammatory response by upregulating IL-10R1, thus improving locomotor function and alleviating spinal cord injury.

Abstract
OBJECTIVE This study aims to investigate the effects of micro ribonucleic acid-34a (miR-34a) on repair and inflammation of rats with spinal cord injury (SCI) through the toll-like receptor (TLR)/nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling pathway. MATERIALS AND METHODS In this study, 12 healthy rats (control group (CG)) and 24 SCI rats (experimental group (EG-1)) were selected as subjects. A total of 12 experimental rats randomly selected from EG-1 were injected with 5 µL agomiR-146 as EG-2 group. Serum levels of miR-146a, TLR, NF-κB, interleukin-8 (IL-8) and IL-6 of rats in CG and EG-1 were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Furthermore, the protein levels of miR-146a, TLR, NF-κB, IL-8 and IL-6 in rats of CG and EG were detected via Western blotting. Spinal cord tissue sections of SCI rats after treatment with agomiR-146 were observed by hematoxylin and eosin staining (H&E) staining. RESULTS The mRNA level of miR-146a in SCI rats was significantly lower than that in healthy rats, and the difference was statistically significant (p < 0.05). The mRNA levels of TLR, NF-κB, IL-8 and IL-6 in SCI rats were markedly higher than those in healthy rats, showing significant differences (p < 0.05). However, the relative mRNA level of miR-146a in EG-2 group was significantly higher than that in EG-1 group, with a significant difference (p < 0.05). Relative level of miR-146a was not significantly different between EG-2 group and CG group (p > 0.05). Meanwhile, the mRNA levels of TLR, NF-κB, IL-8 and IL-6 in EG-2 group were evidently lower than those in EG-1 group, displaying significant differences (p < 0.05). CONCLUSIONS MiR-146a can promote the repair of SCI and reduce inflammatory responses in rats through the TLR/NF-κB signaling pathway.

Abstract
Objective: To analyze the consistency of the clinical phenotype of Alport syndrome between monozygotic twins. Methods: This retrospective study included identical twins with Alport syndrome who met the inclusion and exclusion criteria and were admitted to Peking University First Hospital from January 2000 to March 2019. Their clinical data and urinary epidermal growth factor (uEGF) level were extracted from the on-line registry system of hereditary kidney diseases, and analyzed retrospectively. Results: Three pairs of monozygotic twins with X-linked Alport syndrome from three non-consanguineous families were included. The consistency of the genotype status between the twins tended to confirm their monozygotic relationship. The first twins were term infants, and the twin 1A had a normal birth weight (2 500 g) while twin 1B was small for gestational age (2 450 g) . The other two pairs of twins were preterm, with different birth weights between twins 2 (2A is 2 450 g, 2B is 1 900 g) , but similar birth weights between twins 3. Although raised in the same environment, compared with twin 1A, 1B had obvious growth retardation. However, growth rate in the remaining twins were consistent. The renal abnormalities were not exactly the same between both twins 1 and twins 2, but was almost the same in twins 3. Both 1A and 1B were characterized by massive proteinuria and renal dysfunction, whereas 1B had worse renal function. At the last follow-up, 1A was diagnosed with stage 3 of chronic kidney disease (CKD) whereas 1B was CKD stage 4. Although renal function in twins 2 were normal, 2A had prominent proteinuria(24 h urinary total protein: 0.22 g) while 2B only had microalbuminuria(urinary albumin-to-creatinine ratio: 65 mg/g). Compared with the age-matched healthy controls, the concentration of uEGF normalized by urine creatinine (uEGF/Cr) were significantly lower in these twins. Besides, the twin-boy who had lower estimated glomerular filtration rates had lower uEGF/Cr. However, the extrarenal manifestations such as ocular and acoustic abnormalities were similar between the twins. Twins 2 and 3 showed bilateral temporal retinal thinning, and twins 1 both had binaural mild mid-low frequency sensorineural deafness. Conclusions: Renal manifestations of X-linked Alport syndrome in monozygotic twins may differ from each other, whereas the extrarenal manifestations including ocular and acoustic abnormalities may be consistent. Low birth weight and growth retardation may be associated with the progression of renal dysfunction.

Abstract
Polygenic inheritance plays a central role in Parkinson disease (PD). A priority in elucidating PD etiology lies in defining the biological basis of genetic risk. Unraveling how risk leads to disruption will yield disease-modifying therapeutic targets that may be effective. Here, we utilized a high-throughput and hypothesis-free approach to determine biological processes underlying PD using the largest currently available cohorts of genetic and gene expression data from International Parkinson's Disease Genetics Consortium (IPDGC) and the Accelerating Medicines Partnership-Parkinson's disease initiative (AMP-PD), among other sources. We applied large-scale gene-set specific polygenic risk score (PRS) analyses to assess the role of common variation on PD risk focusing on publicly annotated gene sets representative of curated pathways. We nominated specific molecular sub-processes underlying protein misfolding and aggregation, post-translational protein modification, immune response, membrane and intracellular trafficking, lipid and vitamin metabolism, synaptic transmission, endosomal-lysosomal dysfunction, chromatin remodeling and apoptosis mediated by caspases among the main contributors to PD etiology. We assessed the impact of rare variation on PD risk in an independent cohort of whole-genome sequencing data and found evidence for a burden of rare damaging alleles in a range of processes, including neuronal transmission-related pathways and immune response. We explored enrichment linked to expression cell specificity patterns using single-cell gene expression data and demonstrated a significant risk pattern for dopaminergic neurons, serotonergic neurons, hypothalamic GABAergic neurons, and neural progenitors. Subsequently, we created a novel way of building de novo pathways by constructing a network expression community map using transcriptomic data derived from the blood of PD patients, which revealed functional enrichment in inflammatory signaling pathways, cell death machinery related processes, and dysregulation of mitochondrial homeostasis. Our analyses highlight several specific promising pathways and genes for functional prioritization and provide a cellular context in which such work should be done.

Abstract
Lower eyelid retraction or ectropion bring suffering to the patients both physically and mentally. Efforts to explore pertinent surgical treatments are still needed. Here we have described our preferred surgical technique for lower eyelid ectropion repair with pre-expanded island forehead flaps or pedicled forehead flaps. Between July 2007 and March 2017, a retrospective review of 12 patients who suffered from cicatricial lower eyelid ectropion as a result of trauma, surgery, or infection was conducted. Forehead skin flap based on the superficial temporal artery was expanded depending on the area of defect of the lower eyelid. Tissue expansion, flap transfer, pedicle delaying and division were involved in this process. There were no major complications, such as expander exposure, infection, haematoma or large skin flap necrosis in all the 12 patients. Venous congestion was reported in two patients. No recurrent ectropion was noted in any patient. During the three-month to two-year follow-up all patients were satisfied with the results in terms of the skin texture, colour, and flexibility after the treatment with an expanded forehead skin flap. This study suggests that expanded forehead skin flaps are effective for correction of cicatricial lower eyelid ectropion.

Abstract
Objective: To share related knowledge and experiences with countries along the line, literature regarding current cohort studies was summarized. Distribution, establishment and development of cohort studies among large prospective general population were analyzed in 17 countries of Western Asia and the 16 countries of Central and Eastern Europe. Methods: Literature review was conducted to collect basic information on cohort studies, with descriptive study used to analyze the characteristics of these cohort studies. Results: There were 562 cohort studies with sample size as more than 1 000 stated in Western Asia and Central and Eastern Europe, including 468 (83.27%) carried out in the nation itself and 94 (16.73%) with international multicentered collaboration. According to the nature of cohort studies, 347 (61.74%) were etiologically based. As for the contents involved, 310 (55.16%) of them targeted on chronic/non-communicable diseases, 125 (22.24%) concentrated on maternal and child health. Among those on chronic/non-communicable diseases, 51 (16.45%) were on cancers and 83 (26.77%) on cardiovascular disease studies. There appeared 10 large prospective cohort studies targeting on general population, mainly ongoing in Iran and European countries, with a duration of 8-29 years, including 4 of them with sample size as more than 50 000. In terms of the contents, epidemiological investigation, physical examination and biological samples collection took the major parts. Few papers were published in 9 out of the 10 cohort studies at the early stage of those projects but the number of papers increased annually and stabilized to certain extent. Conclusions: The regional distribution of cohort studies carried out in countries from the Western Asia and Central and Eastern European areas appeared unbalanced. Contents of these designs would mainly involve etiological studies, with focus on non-communicable diseases as cancer, cardiovascular disease, diabetes, respiratory diseases, mental and psychological diseases, and maternal and infant health etc.. However, only few large prospective cohort studies would base on general population.

Abstract
As a top leading cause of cancer death in many countries, colorectal cancer (CRC) has drawn increasing attention to the study of the pathological mechanism. According to the “cancer stem cell hypothesis”, malignancies originate from a small fraction of cancer cells that show self-renewal properties to initiate and sustain tumor growth and tumor metastasis. Therefore, these cancer stem cells (CSC) probably play important roles in tumor recurrence, metastasis, and drug resistance. Previous research reported that lysine-specific histone demethylase 1 (LSD1) maintains cancer stemness through up-regulating stemness markers SOX2 and OCT4. CD133 is believed to be the most robust surface marker for CRC stem cells, however the regulatory effect of LSD1 on stemness of CD133+ CRC has never been reported. In this study, our objectives included: 1) to isolate pure CD133+ and CD133− cells from SW620 cell line; 2) to investigate the effect of LSD1 on the characteristics of CD133+ stem cancer cells by knocking down the target gene. Results suggested that the SW620 cell line had both CD133+ and CD133− subsets. The CD133+ subset exhibited more CSC-like characteristics compared with the CD133− subset with higher viability, colony formation rate, migration and invasion rate, resistance to anti-cancer drugs, and apoptosis in vitro. The CD133+ also induced faster tumor formation and larger tumors in vivo. In the LSD1-knockdown CD133+ cells, the CSC-like characteristics had been all weakened. We conclude that LSD1 was important for CSCs to maintain their “stemness” features, which could be a potential therapeutic target of CRC.

Abstract
Background:Takayasu arteritis (TA) is a form of chronic large vessel vasculitis. Recently, we found that some patients had lung manifestations and abnormal computed tomography (CT) results that cannot be explained by other causes. And so far, the prevalence of pulmonary features of TA is uncertain.Objectives:To investigate the imaging findings of lung involvement in patients with TA by high-resolution CT (HRCT) at a single center of China, and analyze the associations with mortality.Methods:A retrospective study was carried out of TA patients (n = 237, 200 women) who had routine HRCT scanning performed at the time of diagnosis from 2008 to 2018 at Xijing Hospital, Xi’an (China). Radiological manifestations of pulmonary involvement were evaluated from the HRCT images by two experienced radiologists. Patients with a confirmed diagnosis of pulmonary disorder (i.e., infections, tumors, except tuberculosis) have been excluded.Results:The median age of patients was 33 years (range 18-74), and the duration of disease was 66±55 months. Of all the patients, 57.8% (137/237) had abnormal lung HRCT results. Among them, 29.2% (40/137) of patients had pulmonary arterial involvement, including artery stenosis or occlusion. Mild pulmonary interstitial hyperplasia was the most common abnormal HRCT findings (27.4%, 65/237) observed in TA patients. Moreover, the frequencies of stripe/patchy shadows and nodule were 22.7% (53/237) and 15.6% (37/237), respectively. Pleural effusion was rare in these patients (10/237). Additionally, there are 9 cases of active pulmonary tuberculosis, 14 cases of suspected tuberculosis, and 9 cases of obsolete pulmonary tuberculosis. The common symptoms associated with lung were dyspnea (42%), cough (14%), chest pain (9.1%), and hemoptysis (4.9%). In a Cox regression model, there was no significant correlation between pulmonary involvement and mortality (P = 0.001).Conclusion:Pulmonary abnormalities on HRCT scanning is common among patients with TA. Apart from tuberculosis-related lesions and pulmonary arterial involvement, these manifestations are probably part of non-specific systemic inflammation of TA.Disclosure of Interests:None declared
