Abstract
Background The choice of mastectomy compared with breast-conservation therapy (bct) in early-stage breast cancer (esbca) is a complicated decision-making process. Interprovincially, Canada's mastectomy rates vary from 25% to 68%, with Saskatchewan reporting the nation's second-highest mastectomy rate at 63%. The aim of our research was to better understand why women with esbca choose mastectomy rather than bct in Saskatchewan. Methods We created a survey based on a previously developed framework that organizes influencing factors into 3 constructs: clinicopathologic, physician, and individual belief factors. Results Treatment choice was found to be influenced by disease stage and multiple individual belief factors. Compared with their counterparts having stage i disease, women with stage ii disease were significantly more likely to undergo mastectomy [odds ratio (or): 7.48]. Patients rating "worry about cancer recurrence" and "total treatment time" as more influential in their choice were also more likely to undergo mastectomy (or: 3.4 and 1.8 respectively). Conversely, women rating "wanting to keep own breast tissue," "tumour size," and "surgeon's opinion" as influential in their choice were more likely to undergo bct (or: 0.17, 0.66, and 0.69 respectively). Conclusions Our study demonstrates that treatment choices for Saskatchewan women with esbca are influenced primarily by disease stage and individual belief factors. Those findings suggest that women are making their treatment choices predominantly based on individual values and preferences. The use of rates of mastectomy and bct as indicators of quality of care might be misleading. Instead, a shift in attention toward patient-centred care might be more appropriate.

Abstract
Neoadjuvant chemoradiotherapy plus total mesorectal excision (TME) is the standard care for locally advanced middle-low rectal cancer. Some patients could benefit from neoadjuvant chemoradiotherapy to achieve clinical complete response (cCR). Therefore, in recent years, for patients with cCR after neoadjuvant therapy, the "watch and wait" strategy has been widely recommended by their doctors to let them enter "waiting period" without surgery, so that the quality of life is improved. However, the "watch and wait" strategy also has many practical problems that have not been resolved. Firstly, the diagnostic criteria for cCR and pathologic complete response (pCR) are not uniform and different significantly. Secondly, some cCR patients have found tumor regrowth and subsequently underwent salvage surgery during the "watch and wait" period. Thirdly, there is no clinical consensus on the adjuvant therapy for patients during the "watch and wait" period. Fourthly, the role of surgery in patients with cCR is controversial. Finally, we need to accumulate more clinical evidence to confirm whether the "watch and wait" strategy can be selected immediately after achieving cCR for rectal cancer. At the same time, we should find novel molecular markers that can predict the efficacy of chemoradiotherapy. Only rational choice of "watch and wait" strategy will allow more patients with rectal cancer to benefit from chemoradiotherapy.

Abstract
Arsenic acts as a human carcinogen and contributes to skin cancer via mechanisms that remain largely unknown. Recent evidence implicates the perturbation of Wnt, Shh and BMP signals as a potential mechanism. We initiated studies to examine gene expression changes in these signaling pathways. Meanwhile, the antagonistic effect of retinoic acid was explored. In this study, HaCaT and NHEK cells were treated with arsenic trioxide (As2O3) alone or in combination with arotinoid trometamol (retinoic acid receptor agonist). Flow cytometric analysis, PCR array and Western blot were used to determine the potential mechanism and signaling pathways associated with arsenic carcinogenesis. The results showed that low concentration As2O3 could stimulate keratinocyte proliferation, and arotinoid trometamol inhibited the process via regulating the expression of about 20 genes. These genes included components of Wnt signaling (CSNK1A1L, CTNNB1, SFRP1, Wnt10B, Wnt11, Wnt16, Wnt5A, Wnt8A), Shh signaling (C6orf138, HHIP, PTCHD1) and BMP signaling pathway (BMP2, BMP7). The changes of some differentially expressed genes of these signaling pathways in As2O3 treatment group were counteracted by the subsequent arotinoid trometamol treatment. Our data suggest that dysregulation and cross-talk of Wnt, Shh and BMP signals play great roles in the process of arsenic-induced carcinogenesis, which could be antagonized by arotinoid trometamol.

Abstract
Objective: To establish a dynamic compartmental model to predict the impact of HIV testing and treatment and pre-exposure prophylaxis (PrEP) on the annual incidence of HIV infection in men who have sex with men (MSM) in China from 2018 to 2037. Methods: A dynamic compartmental model was developed to describe the HIV epidemic in MSM in China. The model was parameterized using data from the literature available. We used MATLAB 7.0 software for data simulation and graphics rendering. We analyzed HIV transmission among MSM and estimated the impact of expanded HIV testing and treatment and PrEP on HIV elimination in MSM. Results: Under the current policy, the number of new HIV infections would reach 770 000, the infection rate would reach 11.1% and the incidence rate would reach 0.72/100 person years in MSM in the next 20 years. Under the 90%-90%-90% goal, 440 000 new infections (57.7%) would be reduced, the HIV infection rate would decline to 5.7% and the incidence rate would decline to 0.24/100 person years in the next 20 years, but it is still unlikely to achieve the goal of HIV elimination. With 100% PrEP compliance, the required PrEP coverage rates for achieving HIV elimination in the next 10, 15 and 20 years would be 65%, 32% and 19%, respectively. Conclusion: It is necessary to strengthen the comprehensive intervention in MSM, continue to expand HIV testing and treatment, and improve PrEP adherence and coverage to further control and eliminate the epidemic of HIV/AIDS in MSM.

Abstract
Objective: To investigate the characteristics of acute myocardial infarction caused by spontaneous coronary artery dissection(SCAD) in young female patients. Methods: In this casecontrolstudy,127 young(≤55 years) female patients with acute myocardial infarction onset within 1 week in Nanjing first hospital, Xuzhou central hospital, affiliated hospital of Xuzhou medical university, and Lianyungang first people's hospital were enrolled between January 2013 and February 2017,and the clinical data were retrospectively analyzed. According to their clinical manifestations and coronary angiography(CAG) results,the patients were divided into coronary atherosclerosis disease(CAD) group(CAG evidenced atherosclerosis, n=83) and SCAD group(CAG detected coronary artery dissection,n=44).The SCAD patients were subdivided into definite group (the results affirmed from intravenous ultrasound or optical coherence tomography, n=21) and probable group (the CAG results highly confirmed to characteristics of SCAD,but no intravenous ultrasound or optical coherence tomography image affirmation,n=23). Then, according to the different treatment strategies, the SCAD patients were subdivided into conservative treatment group(treated with drugs,n=19) and interventional therapy group(treated with percutaneous coronary intervention,n=25). Results: (1)Compared to CAD group, patients in the SCAD group had less risk factors, such as hypertension history (25.0% (11/44) vs. 45.8% (38/83) , P=0.022) and diabetes history (6.8% (3/44) vs. 21.7% (18/83) , P=0.043),and had lower levels of fasting blood glucose (5.34(4.59,5.87) mmol/L vs. 7.12(5.18,8.60)mmol/L, P=0.001),total cholesterol((3.94±1.14) mmol/L vs. (4.91±1.50) mmol/L, P=0.001),triglyceride(1.42 (0.91,1.64) mmol/L vs. 1.89 (1.23,2.45) mmol/L, P=0.005),and low density lipoprotein cholesterol ((2.24±0.91) mmol/L vs. (2.94±1.16) mmol/L, P=0.001),CAG results showed that patients in the SCAD group had more single vessel lesion (88.6% (39/44) vs. 39.8% (33/83) , P=0.001), and their target lesion stenosis was less severe ( (79.2±22.4) % vs. (91.5±12.1) %, P=0.001). (2) The clinical risk factors such as hypertension history, diabetes history, smoking history, family history of cardiology disease, fasting blood glucose,total cholesterol,triglyceride and low density lipoprotein cholesterol were similar between definite group and probable group (all P>0.05). CAG results showed that prevalence of single vessel lesion (100% (21/21) vs. 78.3% (18/23) , P=0.050) and percent of target lesion stenosis ( (76.9±20.6) % vs. (81.2±24.1) %, P=0.529) were similar between definite group and probable group.(3)There were no significant difference in single vessel(84.0% (21/25) vs. 94.7% (18/19) , P=0.370), target lesion stenosis(85.0(70.0,100.0)% vs. 75.0(50.0,90.0)%, P=0.186),and survival rates in hospital(96.0% (24/25) vs. 100% (19/19) , P=1.000) between interventional therapy group and conservative treatment group. Conclusions: Prevalence of SCAD is highin young female patients with acute myocardial infarction. Acute myocardial infarction patients with less risk factors of CAD and with CAG showing smooth lesion of narrowing segment and normal finding in the other vessels, are more likely to be diagnosed with SCAD.Acute myocardial infarction patients caused by SCAD have high survival rate either receiving percutaneous coronary intervention or drug treatment.

Abstract
Cefuroxime is a second-generation cephalosporin antibiotic that causes immediate hypersensitivity reactions, ranging from mild urticaria to severe anaphylactic shock. Anaphylactic reactions typically involve multiple systems, most notably, the skin and the respiratory and cardiovascular systems. Here, we report the unusual case of a patient who presented with oral cefuroxime-induced anaphylaxis with prominent neurologic manifestations. To identify the drug responsible for the anaphylaxis, we performed skin tests. Based on positive skin-prick test results, the diagnosis of cefuroxime-induced anaphylaxis was confirmed. Therefore, we suggest that clinicians should consider the possibility of a drug-induced anaphylactic reaction when neurologic but not cutaneous symptoms are present. The skin-prick test is a safe and useful diagnostic tool to confirm this kind of immediate drug hypersensitivity.

Abstract
Objective:To analyze the etiology of repeatedly attacks of intractable vertigo and some types of sensorineural deafness whose clinical manifestation were not in conformity with the known spectrum diseases,and explore the screening method to prevent missed diagnosis or misdiagnosis, then provide references for clinical diagnosis and treatment for rare etiology. Method:The authors retrospectively analyzed the clinical manifestations, diagnosis, treatment and prognosis from 4 cases of vertigo sufferers and 2 cases of hearing impairment sufferers whose serological tests were positive for syphilis. All these 6 cases were treated with large doses of penicillin aqueous solutions (24 million U/d), multi-times intravenous infusion, the course of the treatment was 14 d. Result:The clinical manifestations of these 6 patients were lack of characteristic, as well as the results of hearing and vestibular function, imaging diagnosis. Positive syphilis detection of serology and cerebrospinal fluid tests were the main diagnostic basis. After anti-syphilis treatment, 5 cases got satisfied clinical symptoms improvement, 1 case suffered from low-tone sensorineural hearing loss, whose hearing fluctuated recurrently. Conclusion:Syphilis infection may damage the Ⅷ cranial nerve and then lead to vertigo and hearing loss, through chronic syphilitic osteitis of temporal bone, atrophy of organ of corti, osteolytic lesion surrounding the endolymphatic duct, and neurosyphilis. For patients presented with intractable vertigo, and those whose clinical manifestations are not in conformity with the known diseases of unilateral ear or bilateral ears rapidly progressive deafness, syphilis serology screening and validation tests are recommended in case of missed diagnosis or misdiagnosis.

Abstract
Objective: To investigate the feasibility and effectiveness of endoscopicretrograde cholangio-pancreatography(ERCP)in the management of long-term complications after pancreaticoduodenectomy. Methods: From January 2009 to July 2018, the clinical data of 62 patients with biliary or pancreatic long-term complications after pancreatoduodenectomy were reviewed at Department of General Surgery, and the corresponding ERCP were carried out in the multi-disciplinary cooperation.There were 39 males and 24 females.The age was 56.5 years(aging from 13 to 76 years). The time of treatment was 3 months to 20 years after pancreatoduodenectomy.The long-term biliopancreatic complications after pancreatoduodenectomy included 51 cases of biliary calculi, 42 cases of bilioenteric anastomotic stenosis with proximal bile duct dilatation, and 11 cases of pancreaticointestinal anastomosis stenosis with distal pancreatic duct dilatation.All patients received conventional duodenoscopy or single-balloon enteroscopy assisted ERCP under general anesthesia. Results: A total of 95 ERCP were performed in 62 patients, averaging 1.5 times per case.The long-term complications of cholangiopancreatic after pancreatoduodenectomy(ERCP indications) included 56 times of bile duct stones(58.9%), 45 times of bilioenteric anastomatic stricture(47.4%), 11 times of recurrent pancreatitis(11.6%), 6 cases(6.3%) of bilioenteric anastomatic foreign body, 3 times of intrahepatic bile duct stenosis(3.2%). Among the 95 times, 82 times(86.3%) achieved endoscopic endoscopy, 76 times(80.0%) were diagnosed successfully, and 72 times(75.8%) were successfully treated with ERCP.Small intestinal perforation occurred in 1 patient undergoing duodenoscopy, and then healed by surgical repair. Conclusion: Multi-disciplinary collaboration of ERCP is safe and effective in the treatment of long-term complications after pancreaticoduodenectomy, but the long-term effect still needs further clinical follow-up.

Abstract
AIM To investigate the grey matter abnormalities in multiple sclerosis (MS) patients by combined use of double inversion recovery (DIR) sequences and diffusion tensor (DTI) magnetic resonance imaging (MRI) at 3 T. MATERIALS AND METHODS Twenty relapsing-remitting MS (RRMS) patients and 20 healthy control were enrolled in this study. All participants underwent DIR and DTI MRI and completed the Mini-Mental State Examination (MMSE) and Expanded Disability Status Scale (EDSS). The cortical lesions and normal-appearing grey matter (NAGM) of the patient group, as well as the NAGM of the control group were quantitatively analysed using the DIR and DTI images. The average NAGM mean diffusion (MD) and fractional anisotropy (FA) values of the patient group and control group were measured and compared. The correlation between NAGM MD and FA values and the number of cortical lesions, cognitive impairment, as well as the degree of nerve damage were analysed. RESULTS The NAGM of the patient group had average MD and FA values that were significantly different compared with the control group. In addition, the NAGM FA values of the MS patients were negatively correlated with the MMSE score, but positively correlated with the EDSS score. The NAGM MD values of the MS patients were also negatively correlated with the MMSE score, but positively correlated with the EDSS score. CONCLUSIONS The NAGM of MS patients has microstructural damages. The extent of such damage was correlated with the number of cortical lesions. The severity of the damage also correlated with increased severity of cognitive impairment and neural defects.

Abstract
In late 2011, a variant pseudorabies virus (vPRV) emerged in Bartha-K61-vaccinated pig herds, resulting in high morbidity and mortality of piglets in China. Since 2013, the autopsy lesions, histological examinations, virus isolation, phylogenetic analysis and selection pressure analysis of the gE gene of vPRV were recorded for 395 clinical cases, and 5,033 pig serum samples were detected by PRV gE-coated enzyme-linked immunosorbent assay. The major clinical symptoms were abortion in pregnant sows, fatal neurological signs in piglets and respiratory disease in growing pigs. Necrotic splenitis, hepatitis and lymphadenitis, haemorrhagic nephritis and non-suppurative encephalitis were observed by histopathological examination. Typical eosinophilic inclusion bodies were found in the nuclei of liver cells. Using PCR, 110 samples among 395 clinical cases tested positive for the gE gene. Fifteen vPRV strains were isolated and confirmed by sequencing and phylogenetic analysis of the gE gene. The strains shared 97.1%-99.9% nucleotide (nt) and 96.6%-99.5% amino acid (aa) homology with PRV reference strains. Selection pressure analysis showed that one site in the codons of glycoprotein E was under positive selection. Of the 5,033 serum samples, 2,909 were positive by ELISA for a positive rate of 57.8%. These results showed that vPRV was still prevalent in Shandong Province, indicating severe PRV infectious pressure. The preparation of new vaccines against PRV is extremely urgent.

Abstract
BACKGROUND The value of maximum standard uptake value (SUVmax) was overlooked in current studies comparing stereotactic body radiotherapy (SBRT) versus surgery for stage I non-small cell lung cancer (NSCLC). Herein, we aimed to compare the 3-year outcomes based on patients for whom SUVmax were available, and to explore the role of SUVmax in clinical decision-making. METHODS From January 2010 to June 2016, data of eligible patients were collected. Patient variables and clinical outcomes were compared in both unmatched and matched groups using propensity score matching (PSM). Multivariate analysis was performed for predictors of poor outcome. The relationship between treatment approach and survival outcome was also evaluated in subgroup patients stratified by SUVmax level. RESULTS A total of 425 patients treated with either surgery (325) or SBRT (100) were included. Patients receiving SBRT were significantly older, had a higher level of SUVmax and were more likely to have tumor of centrally located. Multivariate analysis showed that SUVmax and tumor size were significant predictors for 3-year OS, LRC, and PFS, while better PFS was also related to peripheral tumor and surgery. The result of PSM analysis also showed that compared to SBRT, surgery could only achieve better PFS. Subgroup analysis indicated that surgery had added advantage of 3-year LRC and PFS for patients in high SUVmax group (SUVmax > 8), but not in low SUVmax group. CONCLUSIONS The study found a superior PFS after surgery while OS and LRC did not differ between SBRT and surgery. Surgery should be recommended for tumor of high SUVmax.

Abstract
Neurofibromatosis type 1 (NF1) is a common genetic disorder caused by mutations in the NF1 gene. Recalcitrant bone healing following fracture (i.e. pseudarthrosis) is one of the most problematic skeletal complications associated with NF1. The etiology of this condition is still unclear; thus, pharmacological options for clinical management are limited. Multiple studies have shown the reduced osteogenic potential of Nf1-deficient osteoprogenitors. A recent transcriptome profiling investigation revealed that EREG and EGFR, encoding epiregulin and its receptor Epidermal Growth Factor Receptor 1, respectively, were among the top over-expressed genes in cells of the NF1 pseudarthrosis site. Because EGFR stimulation is known to inhibit osteogenic differentiation, we hypothesized that increased EREG and EGFR expression in NF1-deficient skeletal progenitors may contribute to their reduced osteogenic differentiation potential. In this study, we first confirmed via single-cell mRNA sequencing that EREG over-expression was associated with NF1 second hit somatic mutations in human bone cells, whereas Transforming Growth Factor beta 1 (TGFβ1) expression was unchanged. Second, using ex-vivo recombined Nf1-deficient mouse bone marrow stromal cells (mBMSCs), we show that this molecular signature is conserved between mice and humans, and that epiregulin generated by these cells is overexpressed and active, whereas soluble TGFβ1 expression and activity are not affected. However, blocking either epiregulin function or EGFR signaling by EGFR1 or pan EGFR inhibition (using AG-1478 and Poziotinib respectively) did not correct the differentiation defect of Nf1-deficient mBMSCs, as measured by the expression of Alpl, Ibsp and alkaline phosphatase activity. These results suggest that clinically available drugs aimed at inhibiting EGFR signaling are unlikely to have a significant benefit for the management of bone non-union in children with NF1 PA.

Abstract
This work reports the effect of two DNA vaccines against salmonid alphavirus 3 (SAV3) in Atlantic salmon. Presmolts were vaccinated by intramuscular injection of plasmids encoding the SAV3 structural polyprotein C-E3-E2-6K-E2 (pCSP), E2 only (pE2), or plasmid without insert (pcDNA3.3). E2 is expressed at the surface of cells transfected with pCSP and internally in cells transfected with pE2. A commercial vaccine based on inactivated SAV (NCPD) was used for comparison. At 10 weeks post-vaccination, only fish vaccinated with pCSP showed antibody against E2 and virus-neutralizing activity. Vaccinated fish were infected with SAV3 to determine protection by virus quantitation in serum after 7 days and scoring of pathological changes after 21 days. Fish vaccinated with both pCSP and NCPD vaccines showed significant virus reduction in serum, while fish vaccinated with pE2 did not. All fish vaccinated with pcDNA3.3 and pE2 showed pathological changes in organs typical of PD, 60% of fish vaccinated with NCPD showed PD pathology, while fish vaccinated with pCSP did not show PD pathology. Taken together, DNA vaccination with pCSP provided strong protection for salmon against SAV3 infection, which in part may be due to production of virus-neutralizing antibodies.
