Abstract
Objective: To investigate the effects of heme oxygenase-1 (HO-1) knockdown on proliferation, invasion and migration of lung adenocarcinoma A549 cells and explore the mechanism. Methods: The expression levels of HO-1 mRNA in human bronchial epithelial cells (HBECs) and human lung cancer cell lines (A549, H1299, H358 and H1993) were detected by real-time quantitative polymerase chain reaction (RT-qPCR), and immunohistochemistry (IHC) was used to detect the expression level of HO-1 in human lung adenocarcinoma specimens. The HO-1 short hairpin RNA (shRNA) was transfected into A549 cells by RNA interference technique. HO-1 stably deleted A549 cells were selected (HO-1 shRNA group) and verified by RT-qPCR and western blot. HO-1 shRNA A549 cells and control shRNA A549 cells were treated with the inducer of autophagy Torin1 or its inhibitor Bafilomycin A1 (Baf A1), respectively. The expressions of autophagic markers LC3B and p62 were determined by western blot. The proliferation, invasion and migration abilities of each group of A549 cells were assessed by cell counting, Transwell and wound healing assays, respectively. Results: The expressions of HO-1 mRNA in lung cancer cell lines (A549, H1299, H358 and H1993) were significantly higher than that of HBECs, and HO-1 upregulated in human lung adenocarcinoma. The expression of p62 protein and the ratio of LC3B-Ⅱ/ LC3B-Ⅰ in no treatment group, Torin1 treatment group and Baf A1 treatment group were significantly higher than those of the corresponding control group (P<0.05). After 11 days of culture, the number of cells in HO-1 shRNA group were 41.8%, 30.4% and 14.0% of the corresponding control group, respectively. The number of lower chamber cells in HO-1 shRNA group were (35.7±2.1), (27.0±1.0) and (38.0±1.0)/field, respectively, which were lower than (66.0±9.2), (39.3±1.2) and (43.0±2.6)/field of the corresponding control group, respectively (P<0.05). The migration distances of HO-1 shRNA group were (7.47±0.91) mm, (4.23±0.82) mm and (5.42±0.24) mm, which were lower than (10.07±1.26) mm, (7.14±0.07) mm and (12.04±0.80) mm of the corresponding control groups, respectively (P<0.05). Conclusion: Knockdown of HO-1 inhibits the proliferation, invasion and migration of A549 cells by impeding autophagy.

Abstract
OBJECTIVE To understand the distribution of nerve fibers and the types of neural cells in Aspidogaster conchiola. METHODS Whole worms were subjected to silver staining, histochemical staining and hematoxylin-eosin (HE) staining, and the nervous systems of the worms were observed. RESULTS There were 3 types of neural cells in the worm head near the cerebral ganglion, including unipolar, bipolar and multipolar neurons, which were divided into 7 types according to the morphology. There was a nerve network on the surface of pharynx and intestinal tract, as well as the reproductive organ, including testis, ovary, lower uterus and penis sac. The nerve network was consisted of circular and longitudinal nerve fibers, and the structure of the nerve network around the mouth was similar to central nerve. CONCLUSIONS The structure of the A. conchiola central nervous system is very complicated, and the neural networks may be associated with the physiologic activity of the worm. Different neural cells may have diverse functions.

Abstract
AIMS Porcine circovirus type 2 (PCV2) can cause postweaning, multisystemic wasting syndrome in pigs, which leads to enormous losses in the swine industry worldwide. Here, a genetically engineered Lactococcus strain expressing the main protective antigen of PCV2, the Cap protein, was developed to act against PCV2 infection as an oral vaccine. METHODS AND RESULTS Expression of the Cap protein was confirmed via western blot, ELISA and fluorescence microscopy. Over 90% of the recombinant pAMJ399-Cap/MG1363 survived a simulated gastrointestinal transit. It also survived the murine intestinal tract for at least 11 days. Then, the safety and immunogenicity of pAMJ399-Cap/MG1363 in orally immunized mice was evaluated. The levels of the sIgA, IgG and cytokines (IL-4 and IFN-γ) obtained from the mice immunized with pAMJ399-Cap/MG1363 were significantly higher than those in the control groups. CONCLUSIONS pAMJ399-Cap/MG1363 can survive in the gastrointestinal transit and effectively induce mucosal, cellular and humoral immune response against PCV2 infection via oral administration. SIGNIFICANCE AND IMPACT OF THE STUDY This study demonstrates the potential of the genetically engineered Lactococcus lactis as a candidate for an oral vaccine against PCV2.

Abstract
Objective: To compare the changes of genioglossus electromyography (GGEMG) with and without continuous positive airway pressure (CPAP) ventilation in moderate to severe obstructive sleep apnea (OSA) patients. Methods: Each of subjects, including male snorers and non-snorers, underwent polysomnography (PSG) with synchronous GGEMG recording with intra-oral bipolar silver ball electrodes at the Sleep Center of Beijing Tsinghua Changgung Hospital from August 2016 to Sepember 2017. Manual CPAP pressure titration and with GGEMG were performed in patients diagnosed moderate to severe OSA. T-test was used to compare the changes of GGEMG in OSA group (n=12, AHI (65.90+23.67) events/h) and control group (n=6, AHI(2.30+1.93) events/h) before and after CPAP treatment. Results: Variables of GGEMG (including tonic, peak and phasic GGEMG) were higher in OSA group than in control group during both wakefulness and non rapid eye movement(NREM) sleep. However, with CPAP treatment, the GGEMG variables were significantly decreased in OSA group during NREM sleep(tonic GGEMG: 1.23%±0.73% vs. 2.54%±1.12%, t=4.024, P=0.002; peak GGEMG: 12.37%±13.19% vs. 26.98%±15.52%, t=2.795, P=0.017; phasic GGEMG: 3.81%±2.47% vs. 8.82%±3.84%, t=5.113, P<0.001). Conclusions: CPAP treatment can eliminate respiratory events and maintain airway patency. It is helpful to normalize the excessive GGEMG response in OSA patients during sleep, which has therapeutic significance to alleviate and prevent genioglossal neuromuscular lesions.

Abstract
Abstract
Background
The heart constantly adapts to maintain cardiac output. In the longer term, this process (remodeling) can manifest as changes in ventricular volume, sphericity, and/or wall thickness, amongst several other morphological indices. Previous studies have shown the significance of remodeling in evaluations of survival, and as a determinant of the clinical course of heart failure. Yet surprisingly, diagnostic measures, typically of left ventricular (LV) mass and ejection fraction, neglect much of the shape information that is available through imaging. A recent UK Biobank study revealed that morphometric atlases show more compelling associations with cardiovascular risk factors, than do LV mass and volumes. While it has been possible to construct shape models from cardiac magnetic resonance imaging (MRI), such a framework is still under development for echocardiography (echo).
Purpose
Despite MRI being long regarded as the gold standard, it is greatly limited by high costs, long scan times and incompatibility with ferromagnetic cardiac devices. In contrast, echo has presented as a convenient alternative, whilst also offering good temporal resolution. The advancements of 3D echo now provide adequate spatial resolution and thus elicit the possibility of conducting more complex analyses on this modality. With the ability to extract LV geometry directly from 3D echo acquisitions, we sought to create dynamic, 3D patient-specific models–and subsequently compare these results to those derived from MRI.
Methods
As part of an ongoing study, 8 volunteers with no known cardiovascular problems (nor family history thereof), were recruited for non-invasive imaging. Cine MRI and 3D echo of the LV were acquired within a 2 hour session. A Siemens Avanto Fit 1.5 T MRI scanner and Siemens ACUSON SC2000 Ultrasound System with a 4Z1c Transducer were used. 3D models of the LV were generated independently from echo (EchobuildR 2.7 prototype software, Siemens Ultrasound) and MRI acquisitions (Cardiac Image Modeller v8.1), and registered to fiducial landmarks (apex, base plane, right ventricular inserts) and myocardial contours.
Results
Euclidian distances between 1682 corresponding points sampled from the surface of echo/MRI models were calculated, and used as a discrepancy measure (Figure). Across the 8 cases, we found an average root mean square deviation (RMSD) of 5.71 mm at end-systole and 6.03 mm at end-diastole. The maximum RMSD for a single model was 9.47 mm (case 8, ES).
Conclusion
We demonstrate that it is possible to create shape models from 3D echo examinations for comparison with MRI. As more cases are collected, we will devise methods to objectively quantify the mismatch that may arise between models derived from the two modalities. The establishment of such a framework would not only provide previously unavailable measures of shape and function, but in turn leverage the significantly wider clinical reach of echocardiography.

Abstract
Objective: To evaluate the efficacy and safety of fecal microbiota transplantation (FMT) for intestinal disorders. Methods: A retrospectively descriptive cohort study was carried out. Clinical data of 2010 patients who underwent FMT and received follow-up for more than 3 months from May 2014 to November 2018 were collected, including 1,206 cases from Tongji University Shanghai Tenth People's Hospital and 804 cases from Nanjing Eastern Military General Hospital. Of the 2,010 patients, 797 were male and 1,213 were female, with a mean age of (49.4±16.5) years old. Inclusion criteria were those with indications for FMT and voluntary treatment of FMT. Pregnant or lactating women, patients with end-stage disease, cases who were participating or participated in other clinical trials within 3 months, and patients with previous bowel history of pathogen infection, oral antibiotics or proton pump inhibitors (PPI) for the recent2 weeks, and those at immunosuppressive state were excluded. Informed consent was obtained from the enrolled patients and their families. There were 1,356 cases of constipation, 175 cases of inflammatory bowel disease, 148 cases of chronic diarrhea, 127 cases of radiation enteritis, 119 cases of irritable bowel syndrome, and 85 cases of autism (complicating with intestinal disorders). FMT donor requirements: (1) 18 to 30 years old non-relatives, non-pregnant healthy adults with healthy lifestyle and good eating habits as volunteers to participate in fecal donation; (2) no administration of antibiotics within 3 months; (3) no chronic diseases such as constipation, irritable bowel syndrome, inflammatory bowel disease, etc., no autoimmune disease, not in immunosuppressive state, no history of malignant disease; (4) negative pathogen examination of infectious diseases (hepatitis B virus, hepatitis C virus, syphilis, HIV, etc.); (5) negative fecal examination (C.difficile, dysentery bacillus, Shigella, Campylobacter, parasites, etc.). The donor requirements after enrollment: (1) physical examination was reviewed once every two months, and the result still met the above requirements; (2) 16S rRNA sequencing was performed for every fecal donation in order to ensure that the composition and diversity of the fecal flora was stable and reliable. The preparation of the stool suspension referred to the Amsterdam criteria and the preparation process was less than 1 hour. The preparation of the FMT capsule was processed by pre-freezing the stool suspension after the preparation of the above suspension, and the frozen sample was transferred into a freeze dryer for freezing. The dried and lyophilized powder was encapsulated in capsules, and the capsule shell was made of acid-resistant hypromellose capsule (No.0) and pediatric-specific capsule (No.3), sealed and packaged in a-20℃ refrigerator. Three ways of accepting FMT treatment pathways included 6-day transplantation after the placement of the nasointestinal tube, 6-day oral FMT capsule transplantation and one-time transplantation through colonoscopy. Intestinal preparation (nasointestinal tube feeding of polyethylene glycol until watery stool) was carried out before transplantation. Other treatments were stopped during treatment and follow-up, and any medication was not recommended when necessary. Results: Of the 2010 patients, 1,497 cases received nasointestinal tube transplantation (nasointestinal tube group), 452 cases oral capsule transplantation (oral capsule group) and 61 cases colonoscopy (colonoscopy group). At 3 time points of 3, 12, and 36 months after FMT, the clinical cure rates and the clinical improvement rates were 41.3% (560/1 356), 35.2% (320/909), 31.4% (69/220), and 29.0% (393/1 356), 27.8% (253/909), 29.1% (64/220), respectively in constipation patients; 33.1% (58/175), 29.9% (35/117), 24.5% (12/49), and 31.4% (55/175), 27.4% (32/117), 57.1% (28/49), respectively in inflammatory bowel disease patients; 87.8% (130/148), 81.8% (81/99), 78.3% (36/46), and 8.1% (12/148), 7.1% (7/99), 4.3% (2/46), respectively in chronic diarrhea patients; 61.4% (78/127), 56.5% (48/85), 47.6% (20/42), and 21.2% (27/127), 15.3% (13/85), 14.3% (6/42), respectively in radiation enteritis patients; 53.8% (64/119), 45.0% (36/80), 6/15, and 21.0% (25/119), 26.2% (21/80), 4/15, respectively in irritable bowel syndrome patients; 23.5% (20/85), 22.8% (13/57), 20.0%(5/25), and 55.3% (47/85), 49.1% (28/57), 40.0% (10/25), respectively in autism patients. Meanwhile the clinical cure rates and the clinical improvement rates at 3, 12, and 36 months were 47.7% (714/1 497), 42.8% (425/994), 39.1% (128/327), and 29.1% (436/1 497), 27.0% (268/994), 28.1% (92/327), respectively in the nasointestinal tube group; 38.7% (175/452), 30.2% (91/301), 33.3% (16/48), and 24.3% (110/452), 26.2% (79/301), 25.0% (12/48), respectively in the oral capsule group; 34.4% (21/61), 32.7% (17/52), 18.2% (4/22), and 21.3% (13/61), 13.5% (7/52), 45.5% (10/22), respectively in colonoscopy group. No serious adverse events occurred during treatment and follow-up period. The adverse event of nasointestinal tube group presented higher ratio of discomfort in respiratorytract accounting for 13.1% (196/1497); the oral capsule group had a higher proportion of nausea and vomiting when swallowing capsules accounting for 7.1% (32/452); the colonoscopy group was mainly diarrhea, accounting for 37.7% (23/61). The above symptoms disappeared after the nasointestinal tube was removed, or after treatment ended, or within 1 to 3 days after hospitalization. Conclusion: FMT is a safe and effective method for the treatment of intestinal dysfunction.

Abstract
Objective: To investigate the effect of genioglossus (GG) activation at sleep onset on the outcome of velopharyngeal surgery in obstructive sleep apnea hypopnea syndrome (OSAHS) patients. Methods: Thirty-five patients between April 2014 and February 2015 in Beijing Tongren Hospital with OSAHS underwent overnight polysomnography with synchronous genioglossus electromyography (GGEMG) using intraoral electrodes. The upper airway (UA) anatomy was evaluated by three-dimensional computer tomography (3D-CT) in OSAHS patients. Then, all of the patients received velopharyngeal surgery, including revised uvulopalatopharyngoplasty (UPPP) with uvula preservation or UPPP combined transpalatal advancement pharyngoplasty. All patients were followed-up using polysomnography 3-6 months after surgery. T-test or Wilcoxon test were used to compare the variables between groups, and Spearman correlation analysis was used to test the correlation between parameters. Results: Thirty-five patients received velopharyngeal surgery. Twenty-two patients (62.86%) were responders, and 13 patients (37.14%) were non-responders. Responders had a higher mean GGEMG during sleep onset (15.31±3.74 vs. 9.92±2.93, t=4.504, P=0.001). The decreased AHI was significantly positively related to the sleep onset mean GGEMG (r=0.541, P=0.004) and the change in GGEMG (r=0.422, P=0.028). The decreased AHI was significantly negatively related to the minimal cross sectional airway area (mCSA,ρ=0.629,P=0.000) and the minimal lateral airway dimension (mLAT, ρ=0.484, P=0.009) at velopharynx. Conclusions: The outcome of velopharyngeal surgery was affected by the mean GGEMG during sleep onset. We speculated that the patient with higher GGEMG at sleep onset and narrower velopharynx were more suitable candidates for velopharyngeal surgery.

Abstract
AIM To identify structural changes in the brain regions of patients with vestibular migraine (VM) so as to better understand its pathophysiology. MATERIAL AND METHODS The differences in grey matter (GM) in patients with VM, patients with migraine without aura (MWoA), and healthy controls (HC) were investigated. Using a GE Signa 3 T magnetic resonance imaging (MRI) system, 3D structural images were acquired from 18 VM, 21 MWoA, and 21 age-, gender-, and education level-matched HC using a T1-weighted magnetization-prepared rapid acquisition gradient-echo (MPRAGE) sequence. The volumetric abnormalities of GM were estimated by voxel-based morphometry. Analysis of variance and Bonferroni multiple comparisons were applied. RESULTS Compared with HC, patients with VM had significantly increased GM volume of the right medial superior frontal gyrus (p=0.008) and the right angular gyrus (p=0.009). Compared to patients with MWoA, patients with VM also had significantly increased volume of the right medial superior frontal gyrus (p=0.001), the right angular gyrus (p=0.008), and the left middle frontal gyrus (p=0.001). CONCLUSIONS The GM volume of some brain regions of patients with VM is significantly larger than the other two groups. The increased GM volume in these brain regions in patients with VM may be related to self-adaptation of the nervous system, leading to an abnormal brain sensitization. Some of the brain regions with increased GM volume identified in this study were involved in assessment, integration, and expectations of pain and were strongly related to mood and anxiety.

Abstract
Objective: Using data of health information system (HIS) of medical institutions to study the incidence and hospitalization of herpes zoster in three districts of Beijing. Methods: According to the different level of economic development and geographical features in Beijing, 3 districts of Xicheng, Changping and Miyun were chosen and all 110 medical institutions of the first level and above in the 3 districts are included in the survey. All the outpatient and inpatient herpes zoster cases in 2015 were retrospectively reviewed by HIS system. After distinguishing the reduplicated cases, Using the first outpatient case as a molecule and the resident population as denominator to estimate the annual incidence rate, as well as the annual hospitalization rate was estimated based on primary diagnostic hospitalized cases as molecule and the resident population as denominator. Results: A total of 32 313 primary visit outpatient cases were investigated, of which 18 360 cases (56.8%) were women and 20 923 cases (64.8%) were ≥50 years old. The overall estimated incidence of the 3 districts was 8.8‰ with an increase trends with age and reached to the highest in ≥80 years old (30.5/1 000). The incidence of Xicheng, Changping and Miyun districts are respectively 16.2‰, 4.0‰ and 5.7‰. A total of 701 primary visit inpatient cases were identified, of which 366 cases (52.2%) were women and 651 cases (92.9%) were ≥50 years old. The estimated annual hospitalization rate was 19.4/100 000, with the primary and secondary diagnostic hospitalization rate are respectively 5.9/100 000 (212 cases) and 13.5/100 000 (489 cases). The disease types of secondary diagnostic inpatient herpes zoster cases were as follows: cardiovascular disease (19.0%, 93 cases), stroke (14.5%, 71 cases), pneumonia/chronic obstructive pulmonary disease (14.1%, 69 cases), tumor (12.5%, 61 cases) and diabetes (5.7%, 28 cases). Conclusion: Most of the herpes zoster cases in Beijing are over 50 years old, and the incidence of female is slightly higher than male. This disease should become a public health issue of great concern.

Abstract
Thymosin beta 10 (Tβ10) is a member of the β-thymosin family. As an actin-binding peptide, thymosin β10 is involved in many important biological activities. Transcriptome sequencing results suggest that Tβ10 may play important roles in the growth of deer antler. In this study, Tβ10 cDNA was isolated from sika deer, and complete open reading frame consisting of 129 nucleotides was obtained by PCR amplification. The predicted peptide was 42 amino acids in length. The sdTβ10 cDNA was cloned and expressed in Escherichia coli resulting in a 6 kDa recombinant-His tagged protein. The recombinant, non-glycosylated peptide was overexpressed in a soluble form and purified by immobilized metal ion affinity chromatography. Functional studies revealed that recombinant Tβ10 stimulated osteoblasts proliferation. This study provides the first evidence that recombinant sika deer Tβ10 promotes proliferation in an osteoblasts cell model.

Abstract
Preoperative radiation therapy has been regarded as the optional neoadjuvant treatment to decrease local recurrence of rectal cancer in addition to surgery. However, its benefit in survival remained obscure. This study was aimed to measure the efficacy of preoperative radiation therapy for survival in stage II and III rectal cancer patients. Retrospective cohort study used the database of Surveillance, Epidemiology and End Results program of the National Cancer Institute in the United States from 1988 to 2011. A total of 49439 patients diagnosed with primary rectal cancer who underwent surgery were included. Clinicopathological characteristics and rectal cancer-specific survival between surgery alone group and surgery plus preoperative radiation therapy group were compared. Rectal cancer patients in surgery plus preoperative radiation therapy group had significantly better survival than those in surgery alone group (72.70% vs. 66.61%, P < 0.001), as well as stratified by stages (stage II: 77.4% vs. 74.3%, P < 0.001; stage III: 68.3% vs. 58.6%, P < 0.001). However, this beneficial impact was only observed after 2000s (P < 0.001). Multivariate survival analysis revealed that preoperative radiation therapy was an independent predictor for better survival in stage III (hazard ratio, 0.795; 95% CI, 0.753-0.840; P < 0.001), but not in stage II (P = 0.70). Preoperative radiation therapy might bring a better survival in stage II and III rectal cancer patients, but only as an independent predictor for stage III patients. As time progressed, preoperative radiation therapy might yield more profit for stage II and III rectal cancer patients.

Abstract
UNLABELLED We performed a 1-year prospective study to see whether zoledronic acid infusion combined with percutaneous kyphoplasty could provide more benefits in the treatment of T12 or L1 osteoporotic vertebral compression fracture (OVCF). INTRODUCTION To investigate and analyze the clinical effects of zoledronic acid (ZOL) in combination with percutaneous kyphoplasty (PKP) in the treatment of OVCF in postmenopausal women. METHODS Included in this study were 101 postmenopausal women patients with T12 or L1 OVCF who received PKP in our hospital between August 2015 and July 2017. They were randomly assigned to a zoledronic acid (ZOL) group (n = 50) or a control group (n = 51). Patients in ZOL group were treated preoperatively with IV infusion of 5 mg ZOL in combination with 0.25μg/d calcitriol and D3 600 mg/d calcium carbonate for a year. Patients in the control group were treated with the same dose of calcitriol and calcium carbonate D3 without ZOL. RESULTS There was no statistically significant difference in age, height, weight, body mass index (BMI), menopause age, and the fractured vertebral body between the two groups. At 6 and 12 months after treatment, bone mineral density (BMD) in ZOL group was higher than that in the control group (p < 0.01); bone markers (NMID, P1NP, and β-CTX) and the VAS score in ZOL group were significantly lower than those in the control group. No new fracture occurred in ZOL group. The incidence of recompression vertebral fracture (RVF) in the control group was 11.7%, while no RVF was detected in any patient in ZOL group. Mild adverse reactions in ZOL group were significantly higher than those in the control group, but all of them were relieved after symptomatic treatment. CONCLUSIONS ZOL IV infusion in combination with PKP is beneficial for the treatment of T12 or L1 OVCF.

Abstract
AIMS We developed a strategy for localized delivery of the LFCA (lactoferricinlactoferrampin), which is actively synthesized in situ by Lactococcus lactis (pAMJ399-LFCA/LLMG1363), and explored the possibility of using pAMJ399-LFCA/LLMG1363 as an alternative additive diet to antibiotics. METHODS AND RESULTS The antimicrobial activities of the LFCA derived from pAMJ399-LFCA/LLMG1363 were tested in vitro. The results showed that LFCA had an inhibitory effect on Staphylococcus aureus, Escherichia coli and Salmonella enteritidis. Then, the pAMJ399-LFCA/LLMG1363 was used as an additive diet for piglets. Our data demonstrated that oral administration of pAMJ399-LFCA/LLMG1363 significantly improved the average daily gain, feed-to-gain ratio, intestinal mucosal integrity and decreased the serum endotoxin and d-lactic acid levels. The mRNA expression levels of intestinal tight junction proteins (including occludin, Claudin-1 and ZO-1) were significantly upregulated by pAMJ399-LFCA/LLMG1363 administration. The serum immunoglobulin G (IgG) levels, intestinal secretory immunoglobulin A (sIgA) levels, IL-2, IL-10 and TGF-β levels were significantly increased by pAMJ399-LFCA/LLMG1363. Furthermore, our data revealed that oral administration of pAMJ399-LFCA/LLMG1363 significantly increased the number of general Lactobacillus, and decreased the total viable E. coli counts in the ileum and cecum contents. CONCLUSIONS We developed a novel pAMJ399-LFCA/LLMG1363 secreting LFCA, which had probiotic effects on the growth performance, intestinal morphology, intestinal barrier function and immunological indices of weaned piglets. SIGNIFICANCE AND IMPACT OF THE STUDY pAMJ399-LFCA/LLMG1363, with probiotic effects on the health of weaned piglets, may be a promising feed additive for weaned piglets.

Abstract
Objective: To understand the prevalence of alcohol use and related factors in HIV positive and HIV negative males. Methods: Baseline data were from the prospective cohort study of comparative HIV and aging research in Taizhou of Zhejiang province from January to December, 2017. The information about alcohol use in the last month was collected through a face-to-face questionnaire interview. Participants were categorized into non-current drinkers, light/moderate drinkers and heavy drinkers according to the US National Institute on Alcoholism and Alcohol Abuse (NIAAA) standard. Results: A total of 1 367 HIV positive males and 2 418 HIV negative males were included. Current alcohol use rate (35.2%, 481/1 367) and heavy alcohol use rate (5.0%, 24/481) were significantly lower in HIV positive males than in HIV negative males (48.0%, 1 161/2 418; 23.5%, 273/1 161), but the proportion of drinking wine and yellow rice wine were significantly higher (21.8%, 105/481; 9.1%, 44/481) in HIV positive males than in HIV negative males (13.5%, 157/1 161; 5.8%, 67/1 161). The multivariate multinomial logistic regression analysis results showed that larger waist circumference, current smoking and regular physical exercise were associated with heavy alcohol use behavior in HIV positive males, and age ≥30 years, current smoking, regular physical exercise, higher score of depressive symptoms, heterosexual transmission route and baseline CD(4)(+)T cells counts of 200-499 cells/μl were significantly associated with mild/moderate alcohol use behavior in HIV positive males. Conclusions: The alcohol use rate was significantly lower in HIV positive males than in HIV negative males in Taizhou. It is important to strengthen intervention on alcohol drinking behavior and chronic disease risk factors, such as larger waist circumference, smoking and so on.

Abstract
Abstract Objective To study the expressions of transforming growth factor-β1 (TGF-β1) and EⅢA-fibronectin (EⅢA-FN) at different time points of antemortem injury, antemortem injury postmortem expression and postmortem injury and to explore their application value in wound age estimation. Methods A model of rat skeletal muscle contusion was established. The rats were randomly divided into normal control group (n=5), antemortem contusion group (n=40), antemortem contusion postmortem expression group (n=110) and postmortem injury group (n=25). The expressions of TGF-β1 and EⅢA-FN after rat skeletal muscles antemortem contusion were detected with immunohistochemical staining. Expression changes of TGF-β1 and EⅢA-FN mRNA in each group were analyzed with real-time fluorescence quantitative PCR. Results Immunohistochemical staining results showed that a large number of polymorphonuclear leukocyte, mononuclear cells and fibroblastic cells showed a strong expression of TGF-β1 in wounded zones 12 h-14 d after antemortem contusion. EⅢA-FN was mainly distributed in the extracellular matrix, 3 to 7 d post-traumatic. Real-time fluorescence quantitative PCR results showed that TGF-β1 and EⅢA-FN mRNA in antemortem injury group reached the peak at 3 and 5 d post-traumatic respectively. The expressions of TGF-β1 and EⅢA-FN mRNA in antemortem contusion postmortem expression group peaked at 6 h and 12 h postmortem. The expression of TGF-β1 and EⅢA-FN mRNA in postmortem injury group 0.5-12 h postmortem was significantly lower than those of the normal control group and the antemortem contusion group. Conclusion TGF-β1 and EⅢA-FN might become a reference index for skeletal muscle wound age estimation.

Abstract
Objective: To assess the use of statins and low-density lipoprotein cholesterol (LDL-C) levels at admission in hospitalized patients aged 75 years and older with acute coronary syndrome (ACS) in China. Methods: Data used in this study derived from the Improving Care for Cardiovascular Disease in China (CCC)-ACS project, a nationwide registry with 150 tertiary hospitals reporting details of clinical information of ACS patients. This study enrolled patients 75 years and older with ACS in CCC-ACS project from November 2014 to June 2017. Patients were divided into two groups according to the history of atherosclerotic cardiovascular disease (ASCVD). Pre-hospital statin use, LDL-C levels at admission and prescription of statins at discharge were reported. Results: A total of 10 899 patients 75 years and older with ACS were enrolled. The median age was 79 years and 58.7% (6 397 cases) were male. Among patients with history of ASCVD, 33.9% (1 028 cases) of them received statins before hospitalization. Among patients without history of ASCVD, 12.7% (996/7 871) received statins before hospitalization. The mean level of LDL-C was (2.4±0.9) mmol/L and LDL-C was <1.8 mmol/L in 24.7% (747 cases) of patients with history of ASCVD. The mean level of LDL-C was (2.6±0.9) mmol/L and LDL-C was <2.6 mmol/L in 51.7% (4 072 cases) of patients without history of ASCVD. At discharge, 91.2% (9 524/10 488) of patients were prescribed with statins in patients without contraindications for statin. Conclusion: In elderly patients with recurrent ASCVD, there was an inadequate statin use before hospitalization and most patients did not reach the LDL-C target level when they had the recurrent events. In the elderly ACS patients without history of ASCVD, more than half of the patients had an ideal LDL-C level. It seems that ideal LDL-C level for primary prevention of ACS in elderly people needs to be reevaluated with further studies.

Abstract
Objective: To investigate the efficacy and safety of mechanical thrombectory with a tri-axial system of the solitaire AB stent through a Navien delivery catheter to treatment acute vertebrobasilar artery occlusion. Methods: The clinical data of 16 consecutive patients with acute ischemic stroke of vertebrobasilar artery occlusion treated with the Solitaire AB device from March 2016 to March 2018 in Department of Neurosurgery, the First Affiliated Hospital, Medical College of Shihezi University, were extracted and then retrospectively analyzed.Recanalization rate as well as complications after treatment were analysized. Also, neurological functions of the patients before and after operation 1 weeks, measured by National Institute of Health stroke scale (NIHSS) score were compared via t test and the clinical outcomes were assessed by modified Rankin score (mRS) at 90 days after operation. Results: There were 10 male and 6 female patients with a median age of 59 years (ranging from 45 to 78 years).Fourteen patients resulted in successfully recanalization, and 2 cases failed both of whose onset to sheath mean time were 8.5 hours.The NIHSS score at 7 days was 13±7, which was significantly decreased compared to the admission NIHSS score 24±4 (P=0.000).No symptomatic intracranial hemorrhage case was found after operation.At 90 days, 8 patients achieved good outcome (mRS 0 to 2), one patient died (mRS 6),two patients moderately seriously disabled (mRS 4).Three patients resulted in moderate outcome (mRS 3).In 3 cases of death,2 patients died due to failure in recanalization,another patient died of severe pulmonary infection. Conclusion: The results suggest that this technique of a tri-axial system used of the Solitaire AB stent through a Navien delivery catheter can effectively retrieve clots from the occlusive artery and improves functional outcome in patients with acute ischemic stroke of vertebrobasilar artery.

Abstract
Objective: To investigate the association between the plasma levels of 20 amino acids and the risk of diabetes in middle-aged and elderly population. Methods: This study was a part of the Chinese multi-provincial cohort study conducted in communities of Shougang. In 2007 and 2012, the population was investigated for diabetes and other risk factors. Blood samples collected from 475 people were tested for various amino acid levels by liquid chromatography-tandem mass spectrometry. A multivariate logistic regression analysis was used to analyze the association between plasma amino acid levels and diabetes risk. Results: The age of the selected population at baseline was (58.7±6.3) years, and the blood glucose level at baseline was (5.68±1.34) mmol/L. Among them, 56 (11.79%) subjects were diabetes. Multivariate logistic regression analyses showed that after adjusting for age, gender, body mass index, systolic blood pressure and dyslipidemia, individuals with plasma branched-chain amino acid (valine, leucine and isoleucine) and cysteine in the highest tertile levels were at high risk of diabetes with the ORs of 3.61 (95% CI 1.48-8.80), 3.27 (95% CI 1.34-7.99), 2.46 (95% CI 1.04-5.84) and 2.09 (95% CI 1.02-4.27), respectively. After 5 years' followed up, 5.73% (24/419) subjects developed diabetes. Compared with those in the lowest tertile, individuals with plasma branched-chain amino acid (total concentration), phenylalanine, and tyrosine levels at baseline in the highest tertile had 3.69 times, 3.61 times and 4.14 times higher risk to develop new diabetes, respectively. In contrast, individuals with plasma glycine level in the highest tertile had only 76% (OR 0.24, 95% CI 0.06-0.91) risk for the development of diabetes compared with those with plasma glycine level in the lowest tertile. Conclusions: The increase in plasma branched-chain amino acid and cysteine levels is significantly associated with an increase in incident diabetes. Subjects with higher levels of branched-chain amino acids and aromatic amino acids (phenylalanine, tyrosine) had a significantly higher risk of developing new-onset diabetes, while those with higher glycine levels had a significantly lower risk of developing diabetes in 5 years.

Abstract
Objective: To compare the clinical effects and the subjective perception of surgeons with three-dimensional (3D) and two-dimensional (2D) laparoscopic C1 radical hysterectomy surgeries for cervical cancer. Methods: The retrospective cohort study was conducted. The clinicopathological data of 101 patients with cervical cancer who received C1 laparoscopic radical hysterectomy (C1-LRH) surgery from June 2015 to August 2017 were collected. Of all patients, 42 cases undergoing 3D laparoscopic surgery and 59 cases undergoing 2D laparoscopic surgery were respectively allocated into the C1-3DLRH group or C1-2DLRH group. The clinical effect and the subjective perception of surgeons were compared between the two groups. Results: (1) There was no significant difference between the C1-3DLRH group and C1-2DLRH group in terms of age, body mass index (BMI), International Federation of Gynecology and Obstetrics (FIGO) stage, pathologic type, etc. (all P>0.05). Compared with C1-2DLRH group, the operation time was significantly shortened [(192±54) vs (221±54) minutes, P<0.01], blood loss was significantly less [(102±88) vs (167±117) ml, P<0.01], and the success rate of inferior hypogastric plexus (IHP) bladder branch preservation was significantly increased [86% (36/42) vs 66% (39/59), P<0.05] in C1-3DLRH group. There were no significant difference in the number of lymph nodes, the incidence of operative complications, the infection rate, the time of catheterization and the length of hospitalization between the two groups (all P>0.05). The long-term bladder function was evaluated at the twelfth month after operation, 39 patients in the C1-3DLRH group and 53 patients in the C1-2DLRH group were completed the survey. The results showed that 13% (5/39) of the patients in the C1-3DLRH group had long-term bladder dysfunction, which was lower than that 21% (11/53) of the C1-2DLRH group, but there was no significant difference between the two groups (χ(2)=0.980, P=0.322). (2) A total of 251 laparoscopic surgeons questionnaires were eligible. The incidence of side effects in the first and second generation of 3D and 2D laparoscopic surgeons was 20.4% (10/49), 6.9% (6/87) and 3.5% (4/115), respectively. The incidence of side effects in the first generation of 3D laparoscopic surgeons was higher than that in the second generation of 3D (χ(2)=5.463, P=0.019) and 2D laparoscopic surgeons (χ(2)=12.475, P<0.01). There was no difference between the second generation of 3D and 2D laparoscopic surgeons (χ(2)=1.208, P=0.272). Conclusions: 3D laparoscopy is advantageous to the preservation of autonomic nerve in C1-LRH operation and may improve the quality of operation compared with 2D laparoscopy. The second generation of 3D laparoscopic device might overcome the side effects of the surgeons.

Abstract
Abstract
Background/Objectives: PAM50 gene profiling assigns each cancer to a single intrinsic subtype. However, individual cancers vary in their adherence to a prototype, and some may exhibit expression patterns that indicate intra-tumor admixture of multiple subtypes. Our objective was to develop admixture metrics from PAM50 gene expression profiles in order to stratify Luminal A cases according to their degree of subtype admixture, and then relate such admixture to clinical and molecular variables.
Methods: We re-constructed scaled, normalized PAM50 profiles for 1,980 cases (674 LumA) in the METABRIC cohort and for each case we computed its Mahalanobis (M-) distance from its assigned centroid and its M-distance from all other centroids. We used t-SNE plots to visualize overlaps in subtype clustering. With Normal-like cases excluded, Median Distance Criteria (MDC) classified a case as Pure if it was located within the 50th percentile of the LumA centroid and >50th percentile from any other centroid. Distance Ratio Criteria (DRC) was computed as the ratio of M-distances from the LumA centroid to the nearest non-assigned centroid; cases were grouped by DRC tertile. Pure and admixed LumA cases were compared on clinical, molecular and survival traits. TCGA LumA cases (n=509) were used for independent validation.
Results: Compared to admixed cases in METABRIC, pure ones by MDC had younger age at diagnosis, smaller tumor size, lower grade and lower stage. Comparisons of the highest (T3, most admixed) to lowest tertile (T1) for DRC revealed even stronger associations. Admixed cases, by both metrics, were more likely to show HER2 gain, high proliferation by AURKA expression, higher PAM50 Risk of Recurrence scores, more frequent TP53 mutation, and less frequent mutation of PIK3CA and CBFB. Similar results were observed in the TCGA validation cohort. LumA-LumB confusion was predominant, but other combinations with LumA were also present. Degree of admixture was associated with overall survival in both cohorts, as was disease-free survival in TCGA, independent of age, grade and stage. (See table for adjusted hazard ratios).
Conclusions: Luminal A breast cancers subgrouped based on PAM50 subtype purity support the hypothesis that admixed cases have worse clinical features and survival. Future analyses will explore more extensive genomic metrics for admixture and their spatial significance within a single tumor.

Abstract
Objective: To compare the clinical outcomes of posterior maxillary implant surgery when using the regular transalveolar approach or with the crestal approach-sinus (CAS-KIT), a device for maxillary sinus membrane elevation by the crestal approach using a special drilling system and hydraulic pressure. Methods: In this retrospective study 887 patients during Jan 2012 to July 2015 in Hangzhou Dental Hospital with underwent either regular transalveolar approach or CAS-KIT approach for maxillary augmentation; whereas 11 patients dropped out for the reason of serious membrane perforations. Totally, 876 patients with 1 204 plants, placed immediately after transalveolar maxillary augmentation, were included in this study. The data analysis was performed by radiological measures to assess the changes in height of maxillary sinus floor after the transalveolar augmentation at different time points. In addition, the complications after surgery, failure rates, osseointegration condition and the performance of rehabilitation were evaluated as well. Results: Five hundred and three patients were experienced with regular transalveolar approach, and 7 patients were drop out for the serious membrane perforations. Thus, 496 patients received 653 implants in this group; the average lifted range in maxillary sinus floor height changes was (4.08±3.45) mm. The complications were minor membrane perforations during procedure in 64 patients, postoperative maxillary sinus infection happening in 2 patients and 13 patients experienced rehabilitation failure. Three hundred and eighty-four patients had CAS-KIT approach with 4 patients dropped out. Three hundred and eighty patients get 551 implants with the mean lifted range of (8.36±4.07) mm in maxillary sinus floor height changes. Minor membrane perforations during procedure occurred in 31 people and 2 got postoperative maxillary sinus infection. The 4 year overall survival rate of 1 204 implants was 97.26%, with four implants fell off after 3 months of rehabilitation and one implant occurred after one year of rehabilitation. Conclusions: The regular transalveolar sinus lift technique is easier and time saving, but the compromised lifting range in maxillary sinus floor height and the comparatively high occurrence of intraoperative membrane perforations should be concerned. Using CAS-KIT could be an alternative method to perform maxillary sinus augmentation with a reduced incidence of complications. There was no statistically difference in implant failure rates and incidence of postoperative maxillary sinus infection between two groups.

Abstract
Objective: To explore the association between long-term changes in blood pressure (BP) levels and the incidence of cardiovascular diseases (CVD). Methods: A total of 5 752 participants, who participated baseline examination in 1992-1993 and re-examination in 2007, were followed up till December 31, 2013 according to the study protocol of the Chinese Multi-provincial Cohort Study. Participants were stratified by baseline BP and re-examination BP and cross-combined into 9 subgroups. The 20-year incidence of acute cardiovascular events, acute coronary heart disease (CHD) and acute stroke events were analyzed and association between disease incidence and 15-year changes in BP were determined using the competing risk regression model. Results: (1) There were 523 CVD events (170 CHD, 373 stroke) during the 20 years follow up. The number of participants with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) of <130/80 mmHg (1 mmHg=0.133 kPa), 130-139/80-89 mmHg, and hypertension were 2 892 (50.3%), 1 328 (23.1%) and 1 532 (26.6%), respectively. (2) Among participants with baseline SBP of 130-139 mmHg or DBP of 80-89 mmHg, 870 (65.5%) progressed to hypertension and 279 (21.0%) maintained at the same stratum over a 15-year follow up period. (3) After adjustment for age, sex, body mass index, smoking status, diabetes, total cholesterol, and high-density lipoprotein cholesterol at baseline, participants maintained SBP/DBP at 130-139/80-89 mmHg had a higher risk of developing acute cardiovascular events, CHD and stroke with the hazard ratios (HR) and 95% confidence interval (95%CI) of 2.04 (1.16, 3.57), 3.29 (1.30, 8.35) and 1.63 (0.80, 3.33), compared with those who maintained their SBP < 130 mmHg and DBP <80 mmHg. Participants whose BP increased from 130-139/80-89 mmHg to hypertension over the follow up period had 2.81-fold (1.84, 4.29), 3.17-fold (1.43, 7.03) and 2.71-fold (1.65, 4.44) higher risk for the incidence of acute cardiovascular events, CHD, and stroke, respectively, compared with participants who maintained their SBP <130 mmHg and DBP <80 mmHg. Conclusions: Participants with SBP/DBP of 130-139/80-89 mmHg have a high long-term risk for progression to hypertension. Sustained exposure to SBP/DBP of 130-139/80-89 mmHg or higher increases the risk of CVD incidence, and our results highlight the importance of early prevention for participants with this BP stratum.

Abstract
UNLABELLED In this large-sample study, we demonstrated that osteogenesis imperfecta (OI) significantly impaired the quality of life (QoL) in children. Moderate/severe OI patients had worse QoL scores than patients with mild OI. Furthermore, the QoL for OI patients was correlated with the presence of pathogenic gene mutations. INTRODUCTION Osteogenesis imperfecta (OI) is a hereditary disease characterized by multiple fragility fractures and progressive skeletal deformities. No detailed investigations about the quality of life (QoL) have been carried out in a large sample of patients with OI. We evaluated the QoL and its influencing factors in a large and well-characterized OI cohort. METHODS We used a validated questionnaire of PedsQL 4.0 to evaluate the health-related quality of life (HRQoL) of children and adolescents with OI. We compared HRQoL among patients with OI types I, III, and IV. The relationship between HRQoL and pathogenic mutations in candidate OI genes was investigated. We also evaluated the influencing factors of HRQoL in OI patients. RESULTS A total of 138 children with OI and 138 healthy controls were enrolled in this study. The HRQoL scores of OI patients were 64.4 ± 30.0, 71.9 ± 22.2, 75.7 ± 24.8, 63.7 ± 24.5, and 68.9 ± 22.0 in physical, emotional, social, school functioning, and total score, respectively, which were significantly lower than those of healthy children (86.5 ± 12.7, 83.3 ± 16.0, 92.1 ± 11.8, 87.5 ± 11.8, and 87.3 ± 10.7, all p < 0.01). Moderate and severe OI (type III/IV) patients had poorer HRQoL scores than patients with mild OI (type I). Gene mutations inducing qualitative defects in type I collagen led to worse HRQoL scores than those with quantitative defects in type I collagen, except in emotional functioning. The total HRQoL score was positively correlated with family income, lumbar, and femoral bone mineral density (BMD) Z-scores and negatively correlated with disease severity and fracture frequency. CONCLUSION HRQoL was significantly impaired in OI patients, and patients with more severe OI had poorer HRQoL scores. For the first time, we found that children with qualitative defects in type I collagen had poorer HRQoL scores than those with quantitative defects in type I collagen.

Abstract
UNLABELLED Rehmanniae Radix Preparata (RRP) improves bone quality in OVX rats through the regulation of bone homeostasis via increasing osteoblastogenesis and decreasing osteoclastogenesis, suggesting it has a potential for the development of new anti-osteoporotic drugs. INTRODUCTION Determine the anti-osteoporotic effect of RRP in ovariectomized (OVX) rats and identify the signaling pathway involved in this process. METHODS OVX rats were treated with RRP aqueous extract for 14 weeks. The serum levels of tartrate-resistant acid phosphatase (TRAP), receptor activator of nuclear factor kappa-Β ligand (RANKL), alkaline phosphatase (ALP), and osteoprotegerin (OPG) were determined by ELISA. Bone histopathological alterations were evaluated by H&E, Alizarin red S, and Safranin O staining. Bone mineral density (BMD) and bone microstructure in rat femurs and lumbar bones were determined by dual-energy X-ray absorptiometry and micro-computed tomography. Femoral bone strength was detected by a three-point bending assay. The expression of Phospho-glycogen synthase kinase 3 beta (p-GSK-3β), GSK-3β, Dickkopf-related protein 1 (DKK1), cathepsin K, OPG, RANKL, IGF-1, Runx2, β-catenin, and p-β-catenin was determined by western blot and/or immunohistochemical staining. RESULTS Treatment of OVX rats with RRP aqueous extract rebuilt bone homeostasis demonstrated by increasing the levels of OPG as well as decreasing the levels of TRAP, RANKL, and ALP in serum. Furthermore, RRP treatment preserved BMD and mechanical strength by increasing cortical bone thickness and epiphyseal thickness as well as improving trabecular distribution in the femurs of OVX rats. In addition, RRP downregulated the expression of DKK1, sclerostin, RANKL, cathepsin K, and the ratio of p-β-catenin to β-catenin, along with upregulating the expression of IGF-1, β-catenin, and Runx2 and the ratio of p-GSK-3β to GSK-3β in the tibias and femurs of OVX rats. Echinacoside, jionoside A1/A2, acetoside, isoacetoside, jionoside B1, and jionoside B2 were identified in the RRP aqueous extract. CONCLUSION RRP attenuates bone loss and improves bone quality in OVX rats partly through its regulation of the canonical Wnt/β-catenin signaling pathway, suggesting that RRP has the potential to provide a new source of anti-osteoporotic drugs.

Abstract
BACKGROUND AND OBJECTIVES Stem cell factor (SCF), the ligand of the c-kit receptor, actively participates in the organ reconstruction and fibrosis associated with various diseases, including kidney disease. However, it remains unclear whether SCF plays a role in kidney aging. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS In the present study, we measured the serum SCF level, estimated glomerular filtration rate (eGFR), and other biological parameters in a Chinese Han group of 892 subjects, and explored the relationship between SCF level and renal function during aging; we sought to define novel biomarkers of kidney aging. RESULTS Multiple linear regression was used to select potential indicators of decline in renal function. Only age, SCF level, and 25% maximum expiratory flow (25% MEF) were significant predictors after redundancy analysis (|r| > 0.70 and P < 0.05). Multiple linear regression showed that the relationship among eGFR, SCF level, and age could be described as follows: eGFR = 154.486 - (0.846 × age) - (0.011 × SCF level). CONCLUSIONS We found no between-gender difference in the effect of SCF on kidney aging. In conclusion, the SCF level is an ideal biomarker of renal aging and may help to predict changes in eGFR during aging.

Abstract
OBJECTIVE To examine whether maternal aspirin use during pregnancy is associated with childhood blood pressure. DESIGN/SETTING A secondary analysis of the Collaborative Perinatal Project, a prospective cohort study including 12 US academic medical centres between 1959 and 1976. POPULATION Singleton births among women with detailed medication information. METHODS We carried out linear and multivariate logistic regression analysis to assess the associations between maternal aspirin exposure and childhood blood pressure at age 7 years. MAIN OUTCOME MEASURES Offspring blood pressure at age 7 years. RESULTS A total of 15 793 women were exposed to aspirin 4 weeks before the last menstrual period or during pregnancy. In utero aspirin exposure may be associated with an 11% (95% CI 0.85- 0.93) and a 20% (95% CI 0.76-0.84) reduced risk of having high systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 7 years of age, and a mean decrease of 0.62 mmHg for SBP and 1.04 mmHg for DBP at 7 years of age. Compared with children born to mothers without aspirin exposure, those whose mothers were exposed to aspirin for at least 7 days during pregnancy had approximately 10% and 27% reduced risk of high SBP and DBP, respectively, and a mean reduction of 0.61 and 1.27 mmHg in SBP and DBP at 7 years of age. The earlier the aspirin exposure occurred during pregnancy, the lower the risk of childhood high blood pressure. CONCLUSION In utero exposure to aspirin may have long-term benefits for childhood blood pressure. TWEETABLE ABSTRACT Maternal aspirin exposure might decrease the risk of childhood blood pressure.

Abstract
OBJECTIVES The mcr-1 gene is the first reported plasmid-mediated colistin resistance gene. It has caused worldwide concern about the colistin resistance in Gram-negative bacteria. The aim of this research was to study the impact of mcr-1 on the selection of high-level colistin resistance (HLCR) mutations in Escherichia coli and Klebsiella pneumoniae. METHODS We detected the HLCR mutation rates of Enterobacteriaceae strains (K. pneumoniae XH209, KP10, and E. coli Q3, ATCC 25922) and their transformants harbouring the mcr-1 gene. Further analysis of the HLCR mutants was conducted by sequencing, plasmid elimination experiment, and real-time quantitative PCR. RESULTS For XH209, mean mutation rate of XH209-pMCR was 1.7 (95% confidence interval (CI) 0.76-2.54) × 10-8, while XH209 and XH209-pCR2.1 showed mutation rates of 2.0 (95% CI, 1.32-2.67) × 10-8 and 2.3 (95% CI 1.47-3.13) × 10-8. For KP10 and its derived strains KP10-pCR2.1, KP10-pMCR, the mutation rates were 3.5 (95% CI 0.77-6.13) × 10-8, 4.8 (95% CI 0.69-8.94) × 10-8 and 4.2 (95% CI 0.95-7.54) × 10-8 respectively. The mutation rates of E. coli strains Q3-pMCR and ATCC25922-pMCR were 3.4 (95% CI 0.19-7.47) × 10-8 and 1.54 (95% CI 0.27-2.8) × 10-9, which were significantly higher than their corresponding non-mcr-1-carrying strains (p < 0.05). CONCLUSIONS Beside the knowledge that mcr-1 mediates low-level colistin resistance, this gene also facilitates selection of HLCR mutants in E. coli, but does not affect K. pneumoniae.

Abstract
In order to compare the pathogenicity of different Tembusu virus (TMUV) strains from geese, ducks and chickens, 56 5-day-old Cherry Valley ducklings which were divided into 7 groups and infected intramuscularly with 7´105 PFU/ml per duck of six challenge virus stocks. The clinical signs, weight gain, mortality, macroscopic and microscopic lesions, virus loads in sera of 1, 3, 5, 7, 11 and 14 dpi and serum antibody titers were examined. The results showed that these viruses could make the young ducks sick, but the clinical signs differed with the different species-original strains. All the experimental groups lose markedly in weight gain compared to the control, but there were no obvious distinctions in weight gains, as well as macroscopic and microscopic lesions of dead ducks between the infected groups. However, the groups of waterfowl-derived strains (from geese and ducks) showed more serious clinical signs and higher relative expressions of virus loads in sera than those from chicken-derived. The mortality of waterfowl groups was 37.5%, and the greatest mortality of chicken groups was 12.5%. The serum antibodies of the geese-species group JS804 appeared earlier and were higher in the titers than others. Taken toghter, the pathogenicity of waterfowl-derived TMUV was more serious than chicken-derived TMUV and JS804 could be chosen as one TMUV vaccine strain to protect from the infection.

Abstract
The self-similar nonlinear evolution of the multimode ablative Rayleigh-Taylor instability (ARTI) is studied numerically in both two and three dimensions. It is shown that the nonlinear multimode bubble-front penetration follows the α_{b}A_{T}(∫sqrt[g]dt)^{2} scaling law with α_{b} dependent on the initial conditions and ablation velocity. The value of α_{b} is determined by the bubble competition theory, indicating that mass ablation reduces α_{b} with respect to the classical value for the same initial perturbation amplitude. It is also shown that ablation-driven vorticity accelerates the bubble velocity and prevents the transition from the bubble competition to the bubble merger regime at large initial amplitudes leading to higher α_{b} than in the classical case. Because of the dependence of α_{b} on initial perturbation and vorticity generation, ablative stabilization of the nonlinear ARTI is not as effective as previously anticipated for large initial perturbations.

Abstract
Objective: To investigate the clinical effect of enhanced recovery after surgery (ERAS) in unilateral total knee arthroplasty (TKA). Methods: Retrospective analysis of 98 patients received unilateral TKA from September 2015 to September 2016 in the Orthopaedic Departmentof Affiliated Hospital of Logistics University of Chinese People's Armed Police Forces.Of the patients, 52 cases were treated by traditional operation (routine group) and the other 46 cases were treated with ERAS concept (ERAS group). The following data were gathered and statistically analyzed between the groups: gender, age, body mass index, preoperative hemoglobin, preoperative visual analogue scale (VAS) score, postoperative visible blood loss, postoperative hemoglobin at 24 hour after operation, blood transfusion rate, postoperative VAS score, length of hospital stay, the satisfaction rate, preoperative and 1 and 6 months postoperative evaluation with hospital for special surgery knee score (HSS), postoperative range of motion (ROM) of knees after 2 weeks, 1 month and 6 months of surgery, incidence rate of complications after surgery.Data between groups were analyzed with one-factor analysis of variance or chi-square test. Results: There was no significant difference in preoperative data between two groups.Postoperative visible blood loss of ERAS group was significantly lower than that in routine group[(224±59) vs (361±70) ml, t=4.723, P<0.01]; postoperative hemoglobin after 24 hours in ERAS group was significantly higher than that in routine group[(109±8) vs (96±10) g/L, t=-3.297, P=0.004]; blood transfusion rate of ERAS group was significantly lower than that in routine group[6.5 %(3/46) vs 46.2%(24/52), χ(2)=19.207, P<0.01]; the 12-hour and 48-hour postoperative VAS scores in ERAS groups were both significantly lower than those in routine group (t=3.708, 3.894, both P<0.05); length of hospital stay in ERAS group was significantly shorter than that in routine group[(6.8±1.2) vs (13.1±2.6) d, t=6.924, P<0.01]; HSS scores of ERAS groups at 1 month and 6 months after surgery were both significantly higher than those in routine group (t=-3.677, -3.594, both P<0.05); knees ROM in ERAS group at 2 weeks and 1 month after surgery were both significantly higher than those in routine group (t=-4.628, -4.442, both P<0.05); the rate of postoperative nausea vomiting in ERAS group was significantly lower than that in routine group[13.0%(6/46) vs 48.1%(25/52), χ(2)=13.852, P=0.002]. VAS score at 1 month after surgery, knees ROM at 6 months after surgery and the satisfaction rate were all comparable between the two groups (t=0.412, -1.026, χ(2)=3.695, all P>0.05). Conclusions: Condition of patients treated by unilateral TKA under ERAS model improves effectively during perioperative period when compared with routine treatment, patients have earlier rehabilitation and better experience in hospital and operation.
