Abstract
The present study was aimed to establish a novel TaqMan real-time PCR (RTm-PCR) for detecting and typing bovine viral diarrhea virus (BVDV), and also to develop a diagnostic protocol which simplifies sample collection and processing. Universal primers and TaqMan-MGB probes were designed from the known sequences of conserved 5' - and 3'-untranslated regions (5'UTR, 3'UTR) of the NADL strain of BVDV. Prior to optimizing the assay, cDNAs were transcribed in vitro to make standard curves. The sensitivity, specificity and stability (reproducibility) were evaluated. The RTm-PCR was tested on the 312 feces specimens collected from persistently infected (PI) calves. The results showed the optimum conditions for RTm-PCR were 17.0 μmol/L primer, 7.5 μmol/L probe and 51.4°C annealing temperature. The established TaqMan RTm-PCR assay could specially detect BVDV without detecting any other viruses. Its detection limit was 1.55×100 copies/μL for viral RNA. It was 10000-fold higher than conventional PCR with excellent specificity and reproducibility. 312 samples were tested using this method and universal PCR from six dairy farms, respectively. Positive detections were found in 49 and 44 feces samples, respectively. The occurrence rate was 89.80%. In conclusion, the established TaqMan RTm-PCR could rapidly detect BVDV and effectively identify PI cattle. The detection limit of RTm-PCR was 1.55 copies/μL. It will be beneficial for enhancing diagnosis and therapy efficacy and reduce losses in cattle farms.

Abstract
OBJECTIVE To investigate the role of miR-198 and its target gene Toll-like receptor 4 (TLR4) of tumorigenesis of gastric cancer (GC). MATERIALS AND METHODS The expression of miR-198 in GC cells was detected by quantitative polymerase chain reaction (qPCR). The proliferation, apoptosis, migration, and invasion of GC cells were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT), flow cytometry, transwell chamber, and wound scratch assay. Bioinformatics analysis for the results of protein chip was performed to identify the target genes of miR-198. TLR4 was further confirmed to be the target gene of miR-198 by TLR4 luciferase reporter assay. RESULTS miR-198 expression level in GC SGC-7901 cells significantly decreased compared with the normal cells. When the miR-198 was overexpressed, the proliferation, migration, and invasion of GC cells were significantly decreased, while the apoptosis was increased. The expression of TLR4 in SGC-7901 cells was significantly higher, while the expression of TLR4 in SGC-7901 cells transfected with miR-198 significantly lowered, which was consistent with the Western blot for TLR4. The luciferase reporter assay confirmed that TLR4 was the target genes of miR-198 in GC SGC7901 cells. CONCLUSIONS miR-198 could induce apoptosis and inhibit the proliferation, migration, and invasion of GC cells through downregulating TLR4 expression.

Abstract
Abstract
Aims
The possibility of endovascular reconstruction of aortic valve, sinus of Valsalva, and ascending aorta by a minimal-invasive single endograft has not been proven in vivo. Combining our own long-term experiences from transcatheter aortic valve replacement (TAVR) and Thoracic Endovascular Repair (TEVAR) for ascending and arch dissection, we designed the special endo-graft: a novel one-piece valved-fenestrated-bifurcated endografting, and tried to endovascularly reconstruct the area from Left ventricular outflow tract to aortic arch in animal experiments.
Methods and results
For 20 healthy adult female pigs weighed between 62.3±2.2 kilograms, we did aortic compute tomography angiography (CTA) examinations and measured morphologic parameters of aortic root. Then we accordingly customized the valved-fenestrated-bifurcated endograft. The endograft was delivered through transapical access and endovascularly reconstructed the segment from aortic valve to proximal part of aortic arch. The overall technical success rate was 95% because of one case of delivery system failure. Instant transesophageal echography (TEE) and aortic CTA confirmed ideal position of the endograft, satisfactory function of aortic valve, and the patency of coronary arteries in all subjects. During follow-up, 12 subjects were sacrificed according to the plan and seven were followed up for 8.1±3.6 months. There was one unplanned death of cardiac infection (unplanned mortality: 5.3%). Follow-up re-examinations (aortic CTA, cardiac ultrasound, and electrocardiogram) found no adverse events. Among 12 sacrificed subjects, there was no evidence of fenestrations alignment lost and no myocardial ischemia according to the pathological analysis.
Conclusion
The novel one-piece valved-fenestrated-bifurcated endografting might be feasible for minimal-invasive reconstruction of aortic root in animal models, thus provided a prospect to simultaneously treat pathologies involving aortic valve and aortic root in endovascular way.

Abstract
BACKGROUND Patients may experience improved quality of life (QoL) without complete clearance of skin disease. The Cutaneous Dermatomyositis Disease Area and Severity Index Activity (CDASI-A) score correlates with the Symptoms and Emotions subscales of Skindex-29, a measure of QoL, down to CDASI-A scores of 7 points (for Symptoms) and 10 points (for Emotions). OBJECTIVES Our goal was to define an important change in disease activity, as measured by the CDASI-A, that results in a meaningful change in QoL in patients with dermatomyositis. METHODS In 103 patients, we assessed the percentage change and actual change in CDASI-A scores needed to achieve a meaningful improvement in QoL, using linear regression models. RESULTS We found that meaningful improvement correlates with 7·86 points (P < 0·001) in Symptoms, and 10·29 points (P < 0·001) in Emotions, after correlating Skindex-29 to an established definition of meaningful change in the Dermatology Life Quality Index (DLQI). For patients with initial CDASI-A scores > 14 points, a 40% change in CDASI-A between the first two visits suggests a meaningful change in Skindex-29. In patients with moderate initial CDASI-A (15-26 points), the changes in CDASI-A resulting in meaningful changes in Symptoms and Emotions were 6 points (P < 0·001) and 7 points (P < 0·001), respectively. For initial CDASI-A scores in the severe range (27-35 points), an improvement in CDASI-A by 11 points (P = 0·030) and 9 points (P = 0·021) leads to a meaningful change in Symptoms and Emotions, respectively. CONCLUSIONS In patients with an initial CDASI-A score > 14 points, a 40% change in the CDASI-A score can be used to indicate a meaningful change in QoL in future dermatomyositis trials. What's already known about this topic? The Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) is a validated disease assessment tool used to capture the extent of cutaneous activity and damage. The Skindex-29 and Dermatology Life Quality Index are standardized and validated measures of quality of life (QoL) for clinical trials and correlate with CDASI Activity (CDASI-A) scores. What does this study add? We identified what change in Skindex-29 scores over two consecutive visits would indicate an important change (a minimal clinically important difference) in QoL. We determined which change in CDASI-A scores over two consecutive visits would lead to a meaningful change in QoL. For patients with an initial CDASI-A score > 14 points, a 40% change in the CDASI-A score over two visits is associated with a meaningful change in QoL. What are the clinical implications of this work? Clinical trials can consider using a 40% change in the CDASI-A score as an end point when assessing the clinical efficacy of drugs.

Abstract
Objective: To explore the prognostic value of the international prognostic index (IPI), the national comprehensive cancer network IPI(NCCN-IPI)and the age-adjusted IPI (aa-IPI) in diffuse large B cell lymphoma. Methods: A total of 311 patients with de novo diffuse large B-cell lymphoma (DLBCL) diagnosed from 2003 to 2012 in Nanfang hospital were included. All patients were divided into CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) and R-CHOP (rituximab, CHOP) groups. Survival analysis was compared among IPI, NCCN-IPI and aa-IPI models. Discrimination of three different prognostic models was assessed using the Harrell's C statistic. Results: A total of 311 patients were analyzed. Among them, 128 patients were treated with CHOP regimen and other 183 patients were treated with R-CHOP regimen. In CHOP groups, both NCCN-IPI (5-year OS: 59.7% vs 26.8%, P<0.001) and aa-IPI (5-year OS: 71.0% vs 25.0%, P<0.001) showed better risk stratification for low-intermediate and high-intermediate group than the IPI (5-year OS: 47.6% vs 36.6%, P=0.003). However, in the patients treated with R-CHOP, NCCN-IPI showed better risk stratification in low, low-intermediate, high-intermediate groups (5-year OS: 96.0% vs 83.0% vs 66.5%, P=0.009). According to the Harrell's C statistic, C-index of IPI, NCCN-IPI and aa-IPI for overall survival (OS) were 0.546, 0.667, 0.698 in CHOP group and 0.611,0.654, 0.695 in R-CHOP group respectively. In patients younger than 60 years old, C-index of IPI, NCCN-IPI and aa-IPI for OS were 0.534, 0.675, 0.698 in CHOP group and 0.584, 0.648, 0.695 in R-CHOP respectively. Conclusion: The NCCN-IPI is more powerful than IPI and aa-IPI in DLBCL patients receiving R-CHOP. aa-IPI is a preferable model in predicting prognosis than IPI and NCCN-IPI in anthracycline-based chemotherapy without rituximab.

Abstract
Objective: To clarify the characteristics of the A20 regulatory changes by analyzing mutations in the non-coding region of the A20 gene in patients with T-cell lymphoma leukemia (T-LCL) . Methods: PCR and nucleotide sequence analysis were used to detect mutations in the non-coding region of the A20 gene, and DNA samples from PBMCs of 52 cases of T-LCL and 99 healthy controls. Results: A missense mutation (c.-672T>G) was detected in the A20 gene promoter from one T-LCL patient, which has been registered as a SNP (rs139054966) in gene bank. Meanwhile, a new mutation was detected in the 3' UTR mRNA (3916 (C>G) ) . These two mutations were absent in other T-LCL samples and controls. Conclusion: The rs139054966 (c.-672T>G) and 3916 (C>G) mutations in the A20 gene were detected in T-LCL patients for the first time. There was also rs139054966 located on the binding region of the transcription factor P53, and its significance remained to be further clarified.

Abstract
Objective: To validate comprehensive geriatric assessment (CGA) system in Chinese elderly diffuse large B cell lymphoma (DLBCL) patients. Methods: Patients ≥ 65 years of age who had been diagnosed with de novo DLBCL were screened for eligibility (n=99). CGA was performed during staging procedures through application of the following instruments: age, comorbidity score according to the Cumulative Illness Rating Score for Geriatrics(CIRS-G), activities of daily living (ADL), and instrumental activities of daily living (IADL). Results: All patients were classified as "ft" , "unfit" , and "frail" . Forty-nine (49.5%), 14 (14.1%), and 34 (36.4%) patients were categorized into the fit, unfit, and frail groups, respectively. The overall response rate was 91.8%, 64.3%, and 69.5% in fit, unfit, and frail group, respectively (χ(2)=9.311, P=0.007). Eleven (22.4%), 7 (50.0%), and 16(44.4%) patients showed disease relapse/progression in fit, unfit, and frail group, respectively (χ(2)=6.309, P=0.040). The 2-year probability of overall survival was 90.6%, 43.0%, and 58.5% in fit, unfit, and frail group, respectively (χ(2)=14.774, P=0.001). The 2-year probability of progression-free survival was 72.9%, 32.5%, and 37.3% in fit, unfit, and frail group, respectively (χ(2)=11.038, P=0.004). Conclusion: The CGA index can predict the clinical outcomes of elderly DLBCL patients in China.

Methods: The clinical data and treatment of 8 extremely severe burn patients in August 2 Kunshan factory aluminum dust explosion accident who were admitted in the 100th Hospital of PLA on August 2nd, 2014, were retrospectively analyzed. There were 4 males and 4 females, aging 22-45 (34±7) years, with total burn area of 55%-98% [(89±15)%] total body surface area (TBSA) and full-thickness burn area of 45%-97% [(80±21)%] TBSA. All the 8 patients were accompanied with severe shock, inhalation injury, and blast injury. According to the requirements of former PLA General Logistics Department and Nanjing Military Command, a treatment team was set up including a special medical unit and a special care unit, with Chai Jiake from the First Affiliated Hospital of PLA General Hospital as the team leader, Zheng Qingyi from the 175th Hospital of PLA (the Affiliated Dongnan Hospital of Xiamen University) as the deputy leader, the 100th Hospital of PLA as the treatment base, and burn care, respiratory, nephrology, nursing specialists from the First Affiliated Hospital of PLA General Hospital, and the burn care experts and nursing staff from the 180th Hospital of PLA, 118th Hospital of PLA, 98th Hospital of PLA, and 175th Hospital of PLA, and nurses from the 85th Hospital of PLA, 455th Hospital of PLA, 101th Hospital of PLA, 113th Hospital of PLA as team members. Treatment strategies were adopted as unified coordination by the superior, unified responsibility of team leader, division of labor and cooperation between team members, and multidisciplinary cooperation led by department of burns. With exception of one patient who received deep vein catheterization before admission, the other 7 patients were treated with deep vein catheterization 0.5 to 3.0 hours after admission to correct hypovolemic shock as soon as possible. Eight patients received tracheotomy, and 7 patients were treated with mechanical ventilation by ventilator in protective ventilation strategy with low tide volume and low volume pressure to assist breathing. Fiberoptic bronchoscopy was done one to three times for all the 8 patients to confirm airway injuries and healing status. Escharectomy and Meek dermatoplasty in the extremities of all the 8 patients were performed 3 to 6 days after injury for the first time. Escharectomy, microskin grafting, and covering of large pieces of allogeneic skin on the trunks of 4 patients were performed 11 to 16 days after injury for the second time. The broad-spectrum antibiotics were uniformly used at first time of anti-infective therapy, and then the antibiotics species were adjusted in time. The balance of internal environment was maintained and the visceral functions were protected. One special care unit was on responsibility of only one patient. Psychological intervention was performed on admission. The rehabilitative treatment was started at early stage and in company with the whole treatment. Results: Acute renal injury occurred in 5 patients within 36 hours after injury and their renal function was restored to normal 4 days after injury due to active adjustment of fluid resuscitation program. No pulmonary complications, such as severe pulmonary infection and ventilator-associated pneumonia, occurred in the survived patients. One of the 8 patients died, and the other 7 patients were cured successfully. The wounds were basically healed in 2 patients in 26 or 27 days by 2 or 3 times of operation, and in 5 patients by 4 or 5 times of operation. The basic wound healing time was 26-64 (48±15) days for all the 7 patients. Conclusions: Treatment strategies of unified coordination by the superior, unified responsibility of team leader, division of labor and cooperation between team members, and multidisciplinary cooperation led by department of burns are the bases to successful treatment. Correcting shock as soon as possible is the prerequisite and closing wound as soon as possible is the key to successful treatment. Comprehensive treatment measures, such as maintaining and regulating the function of viscera, improving the body immunity, and preventing and treating the complications, are the important components to successful treatment. It is emphasized that in the treatment of mass extremely severe burn patients, specialist burn treatment should always be in the dominant position, and other related disciplines may play a part in auxiliary function.

Abstract
BACKGROUND The Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI) is a reliable outcome measure for cutaneous lupus erythematosus (CLE) in adults used in clinical trials. However, it has not been validated in children, limiting clinical trials for paediatric CLE. OBJECTIVES This study aimed to validate the CLASI in paediatrics. METHODS Eleven paediatric patients with CLE, six dermatologists and six rheumatologists participated. The physicians were trained to use the CLASI and Physician's Global Assessment (PGA), and individually rated all patients using both tools. Each physician reassessed two randomly selected patients. Within each physician group, the intraclass correlation coefficient (ICC) was calculated to assess the reliability of each measure. RESULTS CLASI activity scores demonstrated excellent inter- and intrarater reliability (ICC > 0·90), while the PGA activity scores had good inter-rater reliability (ICC 0·73-0·77) among both specialties. PGA activity scores showed excellent (ICC 0·89) and good intrarater reliability (ICC 0·76) for dermatologists and rheumatologists, respectively. Limitations of this study include the small sample size of patients and potential recall bias during the physician rerating session. CONCLUSIONS CLASI activity measurement showed excellent inter- and intrarater reliability in paediatric CLE and superiority over the PGA. These results demonstrate that the CLASI is a reliable and valid outcome instrument for paediatric CLE.

Abstract
Background: Studies showed that dihydroartemisinin (DHA) has significant antitumor effects. However, there have been no relevant reports on gastric cancer resistance to DHA. Aim: To investigate the influence of DHA on the malignant behavior of cisplatin (DDP)-resistant gastric cancer cells SGC7901/DDP and the possible molecular mechanism. Methods: The IC50 of DHA against SGC7901/DDP cells at 48 h was obtained with CCK-8. DHA was used against SGC7901/DDP, with IC50 concentration at 0 µmol/L, 0.5-fold, onefold, and twofold respectively. Then the proliferation activity of SGC7901/DDP from day 1 to day 5 was detected by CCK-8. At 48 h after DHA treatment, we observed apoptosis, invasion, and migration, evaluated autophagy, and detected the expression level of protein related to the regulation of autophagy, apoptosis, angiogenesis and lymphangiogenesis with Western blot. The influence of DHA on cisplatin resistance of SGC7901/DDP was detected through sensitization test and the evaluation of p-gp expression level. Results: The IC50 concentration of DHA against SGC7901/DDP cells at 48 h is 70 µmol/L. DHA significantly inhibited the proliferation of SGC7901/DDP, which was time- and concentration-dependent (all P < 0.05). After having been treated for 48 h by increasing concentrations of DHA (0, 35, 70 and 140 µmol/L), the apoptosis rate increased and the penetrating cell number and scratch healing rate significantly decreased (all P < 0.05). The expression levels of Beclin1 and LC3-II/LC3-I which were corrected with autophagy, and the formation of autophagosomes and autophagous vacuoles increased in a concentration-dependent manner (all P < 0.05). The total PI3K, Akt, and mTOR expression levels did not significantly change, but their phosphorylated products (PI3P, p-Akt [Ser473], and p-mTOR) showed concentration-dependent decreases (all P < 0.05). The expression of caspases-8/9/3 protein significantly increased while the expression of VEGF-A、VEGF-C protein decreased (all P < 0.05). DHA could reverse the resistance of SGC7901/DDP cells to cisplatin after DHA treatment at a nontoxic dose (15.23 µg/mL) with a reversal rate of 2.95. After DHA treatment at different concentrations for 48 h, the expression of p-gp was significantly reduced in a concentration-dependent manner ( P < 0.05). Conclusion: DHA significantly inhibited proliferation, promoted programmed death, and had anti-invasion and antimetastatic effects on SGC7901/DDP cells, probably by upregulating autophagy-related Beclin1 and LC3-II expression and by inhibiting the antiautophagy signaling pathway PI3K/AKT/mTOR, thus promoting autophagic death. In addition, DHA induced caspase-dependent and mitochondrial pathway apoptosis in SGC7901/DDP cells, and reduced VEGF-A and VEGF-C activity to promote antiangiogenesis and antilymphangiogenesis. Furthermore, DHA effectively reversed the cisplatin resistance of gastric cancer cell by inhibiting p-gp expression.

Abstract
Background: Gastric cancer (GC) is prone to metastasis that typically resulted in peritoneal carcinomatosis (PC). GC patients with PC have an extremely poor clinic prognosis. Although GC is sensitive to chemotherapy, PC causes chemotherapy failure. Recent studies showed the combination of intravenous and intraperitoneal chemotherapy can significantly improve the survival rates in GC patients with PC. Aim: To identify the clinical and adverse effects of intravenous chemotherapy combined with intraperitoneal perfusion chemotherapy in the treatment of abdominal peritoneal carcinomatosis arising from gastric cancer. Methods: Retrospective analysis was performed on 49 patients with abdominal peritoneal carcinomatosis from gastric cancer who were treated at the Fujian Medical University Union Hospital between September 2010 and September 2015. The patients were divided into 2 groups based on treatment method: patients subjected to intravenous chemotherapy (n = 27), referred to as the simple group and patients subjected to combined intravenous and intraperitoneal chemotherapy (n = 22), referred to as the combination group. The short-term effects and adverse effects were evaluated based on treatment method, in conjunction with a related review of the results. The long-term effect was evaluated based on the survival rate and median survival time of both groups of patients at 12, 18, 24, 30, 36, and 60 months, as determined through follow-up. Results: Gender, age, ECOG scores before treatment, clinical stages, and the pathologic data of advanced GC patients of the 2 groups were equally distributed. The objective efficacy evaluation results showed that the objective response rate (ORR) and disease control rate (DCR) of the simple group after treatment were significantly lower than in the combination group. The median survival time (MST) of the simple group was (6.57 ± 0.75) months, which was significantly shorter than in the combination group (15.03 ± 2.31) months ( P < 0.05). In addition, the 12-, 18-, 24-, 30-, 36-, and 60-month survival rates of the simple group were all significantly lower than those of the combination group. Furthermore, combined therapy improved the physical condition of the patients. The incidence of adverse reactions in the 2 groups was not statistically significant; neither of the treatments resulted in severe complications. Conclusion: Compared with intravenous chemotherapy alone, the combined intravenous and intraperitoneal perfusion chemotherapy was more effective in improving quality of life and extending survival in time patients with abdominal peritoneal carcinomatosis from gastric cancer. In addition, the treatment produced only mild adverse effects, showing that it is tolerable and therefore worth further clinical study.

Abstract
Objective: To measure the comprehensive geriatric assessment (CGA) in elder non-Hodgkin's Lymphoma (NHL) patients in a cross-sectional study; to compare the differences between Eastern Cooperative Oncology Group (ECOG)-performance status (PS) and CGA. Methods: CGA stratification included the following 3 instrument assessments: activity of daily living (ADL);instrumental activity of daily living (IADL);comorbidity score according to the modified cumulative illness rating score for geriatrics (MCIRS-G). According to CGA and age, NHL patients, aged ≥60 years, were classified as"fit","unfit"and"frail"groups. ECOG-PS was evaluated and compared with CGA. Results: According to CGA, 51.6% senior NHL patients (33 cases) were classified as"fit", 12.5%(8 cases) as"unfit"and 35.9%(23 cases) as"frail". Several comorbidities were observed in majority patients, such as cardiovascular disease, diabetes mellitus and hypertension. In the"younger aged"patients between 60 to 64ys, 25%(3/12) was considered as"frail". However, this proportion increased to 42.9%(6/14) in patients older than 80ys. Moreover, impaired CGA was observed in 38.9%(21/54) of ECOG-PS ≤1 patient. Conclusions: Impaired CGA is as common as approximately half in elderly NHL patients and more than one third even in ECOG-PS ≤1 patients. ECOG-PS may underestimate the impaired fitness function in elder NHL patients.

Abstract
BACKGROUND R333 is a topical janus kinase and spleen tyrosine kinase inhibitor being evaluated for discoid lupus erythematosus (DLE) treatment. There is no validated measure to assess the area of active DLE lesions. OBJECTIVES To evaluate R333 efficacy and assess a technique to measure responsiveness. METHODS Fifty-four patients with DLE were randomized in a double-blind design to R333 or placebo. Primary end point was the proportion of patients achieving ≥ 50% decrease in erythema and scale based on lesional Cutaneous Lupus Erythematosus Disease Area and Severity IndexTM for all treated lesions at week 4. Two-dimensional (2D) area measurements for each lesion were recorded at baseline and weeks 1-6. Eighty-eight photographs (44 pre- and 44 post-treatment) were obtained from the trial and change in size of active areas was analysed by computerized planimetry and physician-assessed area change (PAAC). RESULTS Thirty-six patients were randomized to R333 and 18 patients were randomized to placebo. Primary end point was not achieved. There was a strong association between lesion activity and physician global assessment (P < 0·001). Photos of 42 patients assessed by computerized planimetry demonstrated excellent inter- and intra-rater reliability. Area change by computerized planimetry showed a strong correlation with PAAC (Spearman r = 0·72). Area change by 2D measurements showed a weak correlation with PAAC (Spearman r = 0·29). CONCLUSIONS Four weeks of R333 treatment did not result in significant improvement in lesion activity. Lesion activity and area change using computerized planimetry are better determinants of responsiveness than area change using 2D measurements.

Abstract
Objective: To evaluate the correlation between bile duct injury after transcatheter arterial chemoembolization and the level of hepatic arterial embolization, and to analyze the clinical prognosis of hepatocellular carcinoma patients. Methods: From January18, 2012 to December18, 2014, 21 patients underwent TACE for HCC were retrospectively reviewed, including patients' clinical and pathological data. The clinical outcome and relevant factors for bile duct injury were analyzed. Results: A total of 21 patients were identified with bile duct injury at our single institution. All patients received 48 TACE treatments, including proper hepatic artery (14), left hepatic artery (3), the right hepatic artery (10), left and right hepatic artery (9) and tumor artery branches (12). Thirty-five bile duct injury occurred in 21 patients: 7 cases was close to the tumor, 2 distant to the tumor, 7 at right liver, 2 left liver, 11 both lobes of liver and 6 hepatic hilar. After medical conservative treatment and biliary tract inside and outside drainage, liver function of 10 cases were improved. In four patients with hepatic bile duct stricture and biloma, the effect of drainage was not obvious, which subsequently caused biliary complications such as infection, gallbladder and common bile duct stones. Three patients with liver cirrhosis at decompensation stage developed complications, and one of them died of hepatic encephalopathy. Four patients experienced tumor recurrence during the follow-up period. Conclusions: The location of bile duct injury after transcatheter arterial chemoembolization is quite consistent with the level of hepatic arterial embolization. There may be some blood vessels mainly involved in blood supply of biliary duct. Complete embolism of these vessels may lead to bile duct injuries. Biliary drainage is ineffective in patients with hilar bile duct stricture, and can lead to complications of biliary tract later on.

Abstract
BACKGROUND The Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) and Cutaneous Assessment Tool-Binary Method (CAT-BM) have been shown to be reliable and valid outcome measures to assess cutaneous disease in adult dermatomyositis (DM) and juvenile DM (JDM), respectively. OBJECTIVES This study compared the CDASI and CAT-BM for use by paediatric dermatologists, paediatric rheumatologists and paediatric neurologists in patients with JDM. METHODS Five paediatric dermatologists, five paediatric rheumatologists and five paediatric neurologists each evaluated 14 patients with JDM using the CDASI, CAT-BM, and skin Physician Global Assessment (PGA) scales. Inter-rater reliability, intra-rater reliability, construct validity and completion time were compared. RESULTS Inter-rater reliability for CDASI activity and damage scores was good to moderate for paediatric dermatologists and rheumatologists, but poor for paediatric neurologists. The inter-rater reliability for CAT-BM activity scores was moderate for paediatric dermatologists and rheumatologists, but poor for paediatric neurologists and poor across all specialties for damage scores. Intra-rater reliability for the CDASI and CAT-BM activity and damage scores was moderate to excellent for paediatric dermatologists, rheumatologists and neurologists. Strong associations were found between skin PGA activity and damage scores and CDASI or CAT-BM activity and damage scores, respectively (P < 0·002). The CDASI had a mean completion time of 5·4 min compared with that for the CAT-BM of 3·1 min. CONCLUSIONS Our data confirm the reliability of the CDASI activity and damage scores and the CAT-BM activity scores when used by paediatric dermatologists and rheumatologists in assessing JDM. Significant variation existed in the paediatric neurologists' scores.

Abstract
Treatment of dermatomyositis (DM) is often achieved with a stepwise algorithm. However, the literature lacks quality evidence to support the use of this therapeutic strategy. The result of a stepwise therapeutic strategy in the management of skin-only DM is presented to better understand the clinical outcomes and allow for future studies. A cohort of 102 patients with DM, 41 of whom had skin-only disease, were seen between July 2009 and April 2013 at a referral-based connective tissue disease clinic. The Cutaneous Dermatomyositis Disease Area and Severity Index was used to prospectively assess disease severity and the outcomes in 41 adult patients with skin-only DM were analyzed. Of the 41 patients with skin-only DM, 23 patients (56.1%) received antimalarial medications alone and 18 patients (43.9%) received second- or third-line agents. Ten patients (24.4%) remained at the first level of the treatment algorithm and received only hydroxychloroquine. Prednisone was included in the treatment regimen for 11 patients with skin-only disease (26.8%). The results show that management of cutaneous DM often requires second-line agents because antimalarial medications alone are insufficient to treat most patients with skin-only disease.

Abstract
Objective: To analyze the association of cytogenetic abnormalities with the prognosis of chronic myeloid leukemia (CML) patients in tyrosine kinase inhibitors (TKI) era. Methods: Karyotype analysis of chromosome G-banding was carried out in 387 newly diagnosed CML patients by short-term culture of bone marrow cells. The correlation of cytogenetic abnormalities and CML progression was explored in combination with ABL tyrosine point mutations. Result: Of 387 patients with positive BCR-ABL fusion gene assayed by fluorescence in situ hybridization (FISH) technique, 94.1% (364/387) patients were Ph positive and 5.9% (23/387) Ph negative; 320 patients (87.9%) had a translocation t (9;22) (q34;q11) and 5 (1.4%) a variant translocation t (v;22) . Additional cytogenetic aberrations (ACA) at diagnosis were found in 10.7% (39/387) Ph(+) patients, major route ACA in 22 (56.4%) cases and minor route ACA in 15 (38.5%) cases and 2 patients (5.1%) lacked the Y chromosome (-Y) ; 23.4% (71/303) patients occurred ACA during TKI treatment and the most frequent abnormalities were abnormal chromosome numbersd, which were likely associated with high proportion of disease progression (χ(2)=168.21, P<0.001) and ABL tyrosine point mutations (χ(2)=29.04, P<0.001) . Newly diagnosed CML-CP patients with t (9;22) (q34;q11) had a longer event-free survival (EFS) and disease-free survival (DFS) rates than that of patients with ACA (P=0.037; P=0.003) , while the overall survival (OS) had no significant differences (P=0.209) . As for CML-CP patients that occurred ACA during TKI therapy would have a marked low OS, EFS and DFS (all P<0.001) compared with no ACA occurred patients. Survival of advanced patients that occurred ACA were dramatically reduced. Conclusion: ACA often emerged during the disease progress in CML patients, regular and timely detection of chromosomes karyotype and ABL tyrosine point mutations during TKI treatment was important for therapeutic evaluation, progress and prognosis of CML.

Abstract
BACKGROUND Previous studies have shown that skin disease in dermatomyositis (DM) is best assessed using the Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI). Although the CDASI has been validated for use by dermatologists, it has not been validated for use by other physicians such as rheumatologists and neurologists, who also manage patients with DM and assess skin activity in clinical trials. OBJECTIVES To assess the reliability of the CDASI among dermatologists, rheumatologists and neurologists. METHODS Fifteen patients with cutaneous DM were assessed using the CDASI and the Physician Global Assessment (PGA) by five dermatologists, five rheumatologists and five neurologists. RESULTS The mean CDASI activity scores for dermatologists, rheumatologists and neurologists were 21·0, 21·8 and 20·8, respectively. These mean scores were not different among the specialists. The CDASI damage score means for dermatologists, rheumatologists and neurologists were 5·3, 7·0 and 4·8, respectively. The mean scores between dermatologists and rheumatologists were significantly different, but the means between dermatologists and neurologists were not. The intraclass correlation coefficients (ICCs) for interrater reliability for CDASI activity and damage were good to excellent for dermatologists and rheumatologists, and moderate to excellent for neurologists. The ICCs for intrarater reliability for CDASI activity and damage were excellent for dermatologists and rheumatologists and moderate to excellent for neurologists. The PGA displayed lower interrater and intrarater reliability relative to the CDASI. CONCLUSIONS Our results confirm the reliability of the CDASI when used by dermatologists and rheumatologists. The data for its use by neurologists were not as robust.

Abstract
We carried out a case-control study to examine the relationship between the ATP-binding cassette subfamily B member 1 (ABCB1) gene polymorphisms C1236T, G2677T, and C3435T and risk of acute leukemia in a Chinese population. Between May 2013 and April 2015, we recruited 164 acute leukemia patients and 285 healthy controls, and determined polymorphism genotypes by polymerase chain reaction-restriction fragment length polymorphism. Using unconditional logistic regression analysis, we observed that in comparison to the wild-type sequence, the TT genotype [odds ratio (OR) = 2.15, 95% confidence interval (CI) = 1.12-4.10; P = 0.01] and the T allele (OR = 1.39, 95%CI = 1.05-1.86; P = 0.02) of ABCB1 G2677T were associated with acute leukemia susceptibility. The TT genotype (OR = 2.03, 95%CI = 1.11- 3.69; P = 0.01) and the T allele (OR = 1.39, 95%CI = 1.05-1.85; P = 0.02) of the C3435T polymorphism also increased acute leukemia risk compared to the wild-type form. However, no significant relationship was established between the ABCB1 C1236T variant and this disease. Our results suggest that the ABCB1 G2677T and C3435T sequence variations may affect susceptibility to acute leukemia.

Abstract
OBJECTIVE To explore the role of mitochondrial apoptosis on pulmonary fibrosis in rats with severe scald injury. METHODS According to the random digital table, a total number of 32 Wistar rats were divided into 4 groups: sham burn (group A), burn group (group B), 12-week post burn recovery group (group C), and 12-week post burn recovery plus a second burn injury group (group D). In group A and group B, lung tissues were harvested on post burn day 4. After received first burn injury 12 weeks, the group C and group D received separately a second sham burn injury and burn injury. Lung tissues were harvested on post burn day 4 after the second burn injury. All tissues were examined for cells apoptosis by Terminal-deoxynucleoitidyl Transferase Mediated Nick End Labeling (TUNEL). Pulmonary fibrosis was assessed by Masson trichrome staining and Sirius red staining. The protein expression levels of cleaved Caspase-3, Bax and Bcl-2 were assessed by Western blot. RESULTS Both Masson trichrome staining and Sirius red staining showed obvious pulmonary fibrosis in group C and group D. The apoptosis rates of group B, C and D were significantly higher than that in group A ((15.50±3.30)%, (7.88±3.10)%, (15.88±3.23)% vs (2.10±1.07)%, all P<0.05). Compared to group A, cleaved Caspase-3 levels were significantly higher in group B, C and D ((0.59±0.11), (0.33±0.08), (0.73±0.13) vs (0.16±0.05), all P<0.05). The ratio of Bax/Bcl-2 in group B, C and D also increased significantly ((2.08±0.30), (0.83±0.09), (1.54±0.12) vs (0.64±0.05), all P<0.05). CONCLUSION Severe burn injury can induce pulmonary fibrosis and mitochondrial apoptosis may play an important role in the development of pulmonary fibrosis.

Abstract
OBJECTIVE To explore changes in the proteomics of lung tissue in early stage of burn-blast combined injury in rats. METHODS According to a random digital table, a total number of 18 Sprague Dawley (SD) rats were divided into burn-blast combined injury group (n=9) and blast injury group (n=9). Lung protein samples were collected at 6 h post injury. 2-DE was performed to separate proteins. After silver staining, the protein of differential expression were analyzed by PQ Quest and then identified by matrix-assisted laser desorption/ionization time of fight mass spectrometry (MALDI-TOF-MS). The features of the changes of proteomics of rat lung after burn-blast combined injury were studied by biological spectrometry, protein bank and reference article analysis technique. At same time, pathologic changes of the lung were monitored after injury. RESULTS After removing death drain during the experiment, each group contained 8 rats and the results were analyzed statistically. Well focused and distinct 2-DE maps with good reproducibility were obtained, means of 736±47 and 782±30 protein spots were detected from the blast injury group and burn-blast combined injury group and the matching rates were 91%. From the two groups, 14 differential protein spots expressions were analyzed by MALDI-TOF-MS, of which 10 proteins were up-regulated and 4 proteins were down-regulated in burn-blast combined injury group. 12 different expression proteins were identified in the lung through 2-DE, mass spectrometry and protein date base, including heat shock 27 protein 1, heat shock 70 protein 1, carbonic anhydrase 2, cytochrome c oxidase, ATP synthase subunit alpha, Ca(2+) -transporting ATPase et al, which took part in stress reaction, metabolism, immune response and cytoskeleton. CONCLUSIONS Burn-blast combined injury could induce dramatically changes of proteomics in lung tissue at early stage. The mechanism probably involves several proteins associated with oxidative stress, energy metabolism, immune response and cytoskeleton.
