Abstract
Background The risk of locoregional recurrence (LRR) and the long-term prognosis of breast-conserving surgery (BCS) after neoadjuvant chemotherapy (NAC) are still controversial. This study aimed to evaluate oncological outcomes for patients undergoing BCS after NAC and determine LRR and survival predictors. Methods This study was a retrospective cohort study of patients with locally advanced breast cancer (LABC) who received NAC and underwent BCS or mastectomy from June 2011 to November 2020. LRR, disease-free survival (DFS), and overall survival (OS) were compared in patients undergoing BCS or mastectomy. Univariate and multivariate analyses were performed to determine LRR, DFS, and OS predictors. Results A total of 585 patients were included, of whom 106 (18.1%) underwent BCS and 479 (81.9%) underwent a mastectomy. The LRR rate was 11.3% in the BCS group and 16.3% in the mastectomy group, revealing no significant difference(p = 0.200). In patients who underwent BCS, clinical lymph node status, histological grade and pathological complete response (pCR) were independent factors to predict LRR. There was no significant difference in DFS and OS between the BCS and the mastectomy groups. Multivariable analysis showed that lymph node status, histological grade, molecular subtypes, pCR and Miller&Payne (M&P) classification were independent predictors of DFS. Lymph node status, molecular subtypes and pCR were independent predictors of OS. BCS or mastectomy was not an independent predictor of DFS or OS. Conclusion Compared with mastectomy, BCS after NAC may not increase the risk of local recurrence or mortality, BCS can be performed in selected patients with small tumor size and good response to NAC.

Abstract
The control of Huanglongbing (HLB), one of the most destructive pests of citrus, relies heavily on the reduction of Asian citrus psyllid (ACP), Diaphorina citri Kuwayama. An in-depth understanding of ACP feeding behaviours among citrus plants is urgent for comprehensive management of orchards. An investigation was conducted in 37 citrus orchards in HLB epidemic areas, sampling shoots in the area with aggregation feeding of ACP (ACPf) and shoots in a neighbouring area without ACP feeding (CK), to study the interaction between leaf chemical composition and ACP psyllid feeding behaviours. Results of FTIR showed a strong absorption peak intensity, mainly representing functional groups originating from cell wall components in the leaf with ACP feeding. As compared with the control, cell wall components, such as alkali-soluble pectin, water-soluble pectin, total soluble pectin, cellulose, and hemicellulose, of the cell wall of ACPf increased by 134.0%, 14.0%, 18.0%, 12.5%, and 20.35%, respectively. These results suggest that cell wall mechanical properties significantly decreased in the term of decreases in pectin performance and cellulose mechanical properties. In addition, there was a remarkably lower boron (B) content in leaves and cell wall components with ACP feeding. Further analysis indicated that leaf B content significantly affected leaf cell wall components. Taken together, we provide evidence to demonstrate that the regional distribution of nutrient imbalance in orchards could affect psyllid feeding behaviour by weakening the cell wall structure, resulting in epidemic variation in ACP. This could help us to understand the management of psyllid infections in orchards with unbalanced nutrition.

Abstract
Vertebrate eye lenses are uniquely adapted to form a refractive index gradient (GRIN) for improved acuity, and to grow slowly in size despite constant cell proliferation. The mechanisms behind these adaptations remain poorly understood. We hypothesize that cell compaction contributes to both. To test this notion, we examined the relationship between lens size and shape, refractive characteristics and the cross-sectional areas of constituent fibre cells in mice of different ages. We developed a block-face imaging method to visualize cellular cross sections and found that the cross-sectional areas of fibre cells rose and then decreased over time, with the most significant reduction occurring in denucleating cells in the adult lens cortex, followed by cells in the embryonic nucleus. These findings help reconcile differences between the predictions of lens growth models and empirical data. Biomechanical simulations suggested that compressive forces generated from continuous deposition of fibre cells could contribute to cellular compaction. However, optical measurements revealed that the GRIN did not mirror the pattern of cellular compaction, implying that compaction alone cannot account for GRIN formation and that additional mechanisms are likely to be involved.

Abstract
Objective: To explore the long-term effect of combined surgery for the treatment of congenital tibial pseudarthrosis in children. Methods: The clinical data of 44 children with congenital tibial pseudarthrosis who underwent combined surgery (tibial pseudarthrosis tissue resection, intramedullary rod fixation, Ilizarov external fixator fixation, wrapped autologous iliac bone graft) from August 2007 to October 2011 at the Department of Pediatric Orthopedics, Hunan Children's Hospital were collected retrospectively. There were 33 males and 11 females. The age at the time of surgery was (3.7±2.2)years (range:0.6 to 12.4 years), including 25 cases under 3 years old and 19 cases above 3 years old.Among them, 37 cases were complicated with neurofibromatosis type 1.The operation status, postoperative complications and follow-up results were recorded. Results: The follow-up time after surgery was (10.9±0.7)years (range:10 to 11 years).Thirty-nine out of 44 patients (88.6%) achieved initial healing of tibial pseudarthrosis, with an average healing time of (4.3±1.1)months (range:3 to 10months).In the last follow-up, 36 cases (81.8%) had unequal tibial length, 20 cases (45.4%) had refractures, 18 cases (40.9%) had ankle valgus, 9 cases (20.4%) had proximal tibial valgus, and 11 cases (25.0%) had high arched feet.Nine cases (20.4%) developed distal tibial epiphyseal plate bridging.17 cases (38.6%) had abnormal tibial mechanical axis.Seven cases (15.9%) developed needle infection, and one case (2.3%) developed tibial osteomyelitis. 21 patients (47.7%) had excessive growth of the affected femur.Five patients (11.3%) had ankle stiffness, and 34 patients (77.2%) had intramedullary rod displacement that was not in the center of the tibial medullary cavity.Among them, 8 cases (18.1%) protruded the tibial bone cortex and underwent intramedullary rod removal.18 children have reached skeletal maturity, while 26 children have not been followed up until skeletal maturity. Conclusion: Combined surgery for the treatment of congenital pseudarthrosis of the tibia in children has a high initial healing rate, but complications such as unequal tibia length, refracture, and ankle valgus occur during long-term follow-up, requiring multiple surgical treatments.

Abstract
Objective: To investigate the clinicopathological features, treatment and prognosis of patients with RET fusion positive non-small cell lung cancer (NSCLC). Methods: A total of 1 089 NSCLCs were retrieved at Affiliated Hospital of Jiangnan University from August 2018 to April 2020. In all cases, multiple gene fusion detection kits (fluorescent PCR method) were used to detect the gene status of RET, EGFR, ALK, ROS1, KRAS, BRAF and HER2; and immunohistochemical method was used to detect the expression of PD-L1 and mismatch repair related proteins. The correlation between RET-fusion and patients' age, gender, smoking history, tumor stage, grade, pathologic type, and PD-L1, mismatch repair related protein expression was analyzed. Results: There were 22 cases (2.02%) detected with RET fusion-positive in 1 089 NSCLC patients, in which 11 males and 11 females; and the median age was 63.5 years. There were 20 adenocarcinomas, including 11 acinar predominant adenocarcinoma (APA), five solid predominant adenocarcinoma (SPA) and four lepidic predominant adenocarcinoma (LPA); There were one case each of squamous cell carcinoma (non-keratinizing type) and sarcomatoid carcinoma (pleomorphic carcinoma). There were 6 and 16 patients with RET fusion-positive who were in stage Ⅰ-Ⅱ and Ⅲ-Ⅳ respectively, and 16 cases with lymph node metastasis, 11 cases with distant metastasis. Among RET fusion-positive cases, one was detected with HER2 co-mutation. The tumor proportion score of PD-L1≥1% in patients with RET fusion positive lung cancer was 54.5% (12/22). Defects in mismatch repair protein expression were not found in patients with RET fusion positive NSCLC. Four patients with RET fusions positive (two cases of APA and two cases of SPA) received pratinib-targeted therapy, and two showed benefits from this targeted therapy. Conclusions: The histological subtypes of RET fusions positive NSCLC are more likely to be APA or SPA. RET fusion-positive NSCLC patients are associated with advanced clinical stage, lymph node metastases, and they may benefit from targeted therapy with RET-specific inhibitors.

Abstract
OBJECTIVE The incidence of osteoarthritis (OA) in menopausal women is significantly higher than in same-aged men. Investigating the role of subchondral osteoblasts in estrogen deficiency-induced OA may help elucidate the pathological mechanism, providing new insights for the diagnosis and treatment of menopausal OA. METHODS A classical ovariectomy-induced OA (OVX-OA) rat model was utilized to isolate primary articular chondrocytes and subchondral osteoblasts, which were identified and then cocultured in Transwell. The expression of chondrocyte anabolic and catabolic indicators was evaluated. The differentially expressed proteins in the conditioned medium (CM) of osteoblasts were identified by Liquid Chromatograph-Mass Spectrometer (LC-MS/MS). Normal chondrocytes were treated with osteoblast CM, and then RNA sequencing was performed on the treated chondrocytes. KEGG was used to identify significant enrichment of signaling pathways, and Simple Western was used to verify the expression of related proteins in the signaling pathways. RESULTS Coculture of OVX-OA subchondral osteoblasts with chondrocytes significantly downregulated the expression of the anabolic indicators and upregulated the expression of the catabolic indicators in chondrocytes. 1,601 proteins were identified in both normal and OVX osteoblast culture supernatants. Protein-protein interaction network analysis revealed that Sparc was one of the hub proteins. The AMPK/Foxo3a signaling pathway of chondrocytes was downregulated by OVX-OA osteoblasts CM. AICAR, the AMPK agonist, partially reversed the catabolic effect of OVX-OA osteoblasts on chondrocytes. CONCLUSIONS Sparc secreted by OVX-OA subchondral osteoblasts can downregulate the AMPK/Foxo3a signaling pathway of chondrocytes, thereby promoting chondrocyte degeneration.

Abstract
This study was conducted to investigate the effect of different varieties of rapeseed meal (RSM) with different concentrations of glucosinolates (Gls) and erucic acid (EA) on performance and egg quality of laying ducks. A total of 576 twenty eight-wk-old laying ducks were randomly allocated to 4 treatments. Each treatment had 8 replicates of 18 laying ducks raised in 6 adjacent cages with 3 laying ducks per cage. The control diet was corn soybean meal based without RSM. Three varieties of RSM varying in Gls concentrations were supplemented to the base diet at 10% by substituting soybean meal to formulate the three RSM diets. The experiment lasted 12 wk. Diets with 10% RSM decreased average egg weight (P < 0.01) and feed intake (P = 0.07) compared with the control diet, but there was no significant difference in laying performance among the 3 RSM diets. RSM increased color value (P < 0.05) and crude protein (CP) content (P < 0.05) of yolk compared with the control diet, but had no significant effects on the other egg quality indexes including eggshell strength, albumen height, Haugh unit, and the composition ratio of eggshell, albumen and yolk. RSM decreased total monounsaturated fatty acids (MUFA) (P < 0.01) and increased total polyunsaturated fatty acids (PUFA) (P < 0.01) of yolk, but total saturated fatty acids (SFA) proportions and UFA/SFA ratio of egg yolk were not significantly affected by RSM. RSM increased deposition of trimethylamine (TMA) and 5-vinyl-1,3-oxazolidine-2-thione (5-VOT) in yolk (P < 0.01); moreover, the high Gls RSM increased deposition of TMA (P < 0.01) and 5-VOT in yolk (P < 0.01) compared with the RSM varieties low in Gls. These results suggested that dietary inclusion of 10% RSM decreased egg weight of laying ducks, and affected yolk quality especially yolk color, fatty acid profile, CP, TMA, and 5-VOT content of yolk. Moreover, RSM with higher Gls concentration resulted in higher deposition of TMA and 5-VOT in egg yolk.

Abstract
AIM Slc26a9 is a member of the Slc26 multifunctional anion transporter family. Polymorphisms in Slc26a9 are associated with an increased incidence of meconium ileus and diabetes in cystic fibrosis patients. We investigated the expression of Slc26a9 in the murine pancreatic ducts, islets and parenchyma, and elucidated its role in pancreatic ductal electrolyte and fluid secretion and endocrine function. METHODS Pancreatic Slc26a9 and CFTR mRNA expression, fluid and bicarbonate secretion were assessed in slc26a9-/- mice and their age- and sex-matched wild-type (wt) littermates. Glucose and insulin tolerance tests were performed. RESULTS Compared with stomach, the mRNA expression of Slc26a9 was low in pancreatic parenchyma, 20-fold higher in microdissected pancreatic ducts than parenchyma, and very low in islets. CFTR mRNA was ~10 fold higher than Slc26a9 mRNA expression in each pancreatic cell type. Significantly reduced pancreatic fluid secretory rates and impaired glucose tolerance were observed in female slc26a9-/- mice, whereas alterations in male mice did not reach statistical significance. No significant difference was observed in peripheral insulin resistance in slc26a9-/- compared to sex- and aged-matched wt controls. In contrast, isolated slc26a9-/- islets in short term culture displayed no difference in insulin content, but a significantly reduced glucose-stimulated insulin secretion compared to age- and sex-matched wt islets, suggesting that the impaired glucose tolerance in the absence of Slc26a9 expression these is a pancreatic defect. CONCLUSIONS Deletion of Slc26a9 is associated with a reduction in pancreatic fluid secretion and impaired glucose tolerance in female mice. The results underline the importance of Slc26a9 in pancreatic physiology.

Abstract
AIM To develop a nomogram based on computed tomography (CT) texture analysis for the preoperative prediction of visceral pleural invasion in patients with cT1N0M0 lung adenocarcinoma. MATERIALS AND METHODS A dataset of chest CT containing lung nodules was collected from two institutions, and all surgically resected nodules were classified pathologically based on the presence of visceral pleural invasion. Each nodule on the CT image was segmented automatically by artificial-intelligence software and its CT texture features were extracted. The dataset was divided into training and external validation cohorts according to the institution, and a nomogram for predicting visceral pleural invasion was developed and validated. RESULTS Of a total of 313 patients enrolled from two independent institutions, 63 were diagnosed with visceral pleural invasion. Three-dimensional (3D) CT long diameter, skewness, and sphericity, and chronic obstructive pulmonary disease were identified as independent predictors for visceral pleural invasion by multivariable logistic regression. The nomogram based on multivariable logistic regression showed great discriminative ability, as indicated by a C-index of 0.890 (95% confidence interval [CI]: 0.867-0.914) and 0.864 (95% CI: 0.817-0.911) for the training and external validation cohorts, respectively. Additionally, calibration of the nomogram revealed good predictive ability, as indicated by the Brier score (0.108 and 0.100 for the training and external validation cohorts, respectively). CONCLUSIONS A nomogram was developed that could compute the probability of visceral pleural invasion in patients with cT1N0M0 lung adenocarcinoma with good calibration and discrimination. The nomogram has potential as a reliable tool for clinical evaluation and decision-making.

Abstract
In addition to offering methionine, 2-hydroxy-4-methylthiobutyric acid (HMTBa) is also an organic acid and shows excellent bacteriostasis. Therefore, 3 experiments were conducted to determine the influence of drinking water supplemented HMTBa in combination with acidifier on performance, intestinal development, and microflora in broilers. The addition of different concentration (0.02–0.20%) of the blend of HMTBa and other acids significantly reduced the pH of water and exerted antimicrobial activity in dose-dependent manner in vitro. The outcomes from animal trial consisting of the drinking water with blended acidifier at 0.00, 0.05, 0.10, 0.15, and 0.20% indicated that the water with 0.15 or 0.20% acidifier resulted in linear and quadratic higher body weight at 42 d, gain and water consumption during 1 to 42 d (P < 0.05). In experiment 3, responding to graded blended acidifier in drinking water, birds receiving 0.10, 0.15, and 0.20% acidifier decreased the internal pH of gastrointestinal tract and muscle, and exhibited increased duodenal weight, length, villus high, and the ratio of villus high to crypt depth. Drinking water with 0.2% blended acidifier increased the abundance of probiotics (Bacteroidaceae, Ruminococcaceae, and Lachnospiraceae) and decreased the account of pathogenic bacteria such as Desulfovibrionaceae. Alternations in gut microflora were closely related to the metabolism of carbohydrate, amino acid, and vitamins. These findings, therefore, suggest that drinking water with 0.10 to 0.13% the combination HMTBa with acidifier might benefit to intestinal development and gut microbiota, and the subsequent produce a positive effect on the performance of broilers.

Abstract
BACKGROUND Arteriovenous fistulas, a major treatment for end-stage kidney disease, frequently require endovascular reinterventions to maintain haemodialysis function. Drug-coated angioplasty balloons (DCBs) were developed with the intention of reducing reintervention rates. The aim of this study was to perform a systematic review and meta-analysis of DCBs in the treatment of failing haemodialysis access. METHODS Electronic databases were searched systematically to identify all relevant RCTs and any follow-up studies from RCTs. Pooled estimates of dichotomous outcomes were calculated using the odds ratio (OR) and 95 per cent confidence interval. Effect data are presented as summary hazard ratio and 95 per cent confidence interval. RESULTS Some 19 studies from 18 RCTs and comprising 1898 patients were included in the meta-analysis. Compared with plain balloon angioplasty (PBA), DCB use was associated with higher target-lesion primary patency (HR 0.60, 95 per cent c.i. 0.45 to 0.79), access-circuit primary patency (HR 0.67, 0.56 to 0.80), and less target-lesion revascularization (TLR) within 6 months (OR 0.33, 0.23 to 0.47). No difference was observed between DCB and PBA in 12-month TLR (OR 0.62, 0.28 to 1.37). Mortality after DCB use was similar to that associated with PBA use at 6 months (OR 1.20, 0.65 to 2.21) and 12 months (OR 0.99, 0.66 to 1.49), and was higher at 24 months (23.1 versus 16.6 per cent), although the difference was not statistically significant (OR 1.53, 0.92 to 2.53). CONCLUSION Drug-coated balloon angioplasty of haemodialysis fistulas is associated with higher patency rates and lower rates of reintervention in the short to mid term. Although mortality rates appeared to be higher with drug-coated angioplasty at 24 months, this did not reach statistical significance.

Abstract
Objective To investigate the association between the recurrence score (RS) obtained by Oncotype DX 21-gene test and long non-coding RNA (lncRNA) MALAT1 expression in early and estrogen receptor-positive (ER+) breast cancer. Materials and Methods The Oncotype DX 21-gene test and MALAT1 expression detection were performed in tumor samples from 76 ER+ and early breast cancer patients with the Surplex liquid chip. The RS value was calculated based on the expression of total 21 genes. The level of MALAT1 was measured in both tumor tissue and para-tumor tissue, and relatively quantified with an internal control gene. Mann–Whitney U-test or Kruskal–Wallis test were used to analyze the association between MALAT1 level and different clinical pathological characteristics, including age, tumor stage, disease grade, lymph node status, Ki-67 expression, and progesterone receptor (PR) status. The association between the RS and different characteristics was analyzed by Wilcoxon rank-sum test. Correlation between two parameters was analyzed by Spearman’s rank correlation analysis. Results The expression of MALAT1 was more abundant in tumor tissue (2.992 ± 2.256) than that in adjacent normal tissue (1.641±1.438, Z=−2.594, p=0.009), and it was not correlated with any clinical pathological characteristics. According to the old criteria for RS stratification, 52.7% of patients were in low risk (RS<18), 36.8% of patients were in medium risk (18≤RS≤30), and 10.5% of patients were in high risk (RS>30). While under the new criteria, 18.4% were in low risk group (RS<11), 63.2% were in a medium risk group (11≤RS≤26), and 18.4% were in a high risk group (RS>26). The Oncotype DX 21-gene results only correlated with Ki-67 expression under both new and old criteria, and it was not related with other cancer characteristics. The expression of lncRNA MALAT1 was significantly correlated with the Oncotype DX 21-gene results under the old criteria. Conclusion MALAT1 is a novel breast cancer biomarker independent of tumor stage, disease grade and lymph node status. MALAT1 level is associated with the Oncotype DX 21-gene RS value. Therefore, combination of MALAT1 and the Oncotype DX 21-gene test may be used to predict prognosis in ER+ and early stage breast cancer.

Abstract
Purpose The efficacy of primary site surgery in patients with de novo stage IV breast cancer remains controversial. However, few real-world studies have evaluated the benefits of local surgery on the primary site of stage IV breast cancer in China. The purpose of this study was to investigate the role of local surgery in the de novo stage IV breast cancer. Materials and Methods Women with metastatic breast cancer at diagnosis were identified from Guangxi medical university cancer hospital (China) database from 2009 to 2017. The clinical and tumor features, surgical treatment, and survival rates were compared between surgical and non-surgical patients. Results Two hundred forty-three patients were included, of whom 125 underwent primary site surgery. Patients who underwent surgery were more often had small primary tumors, fewer lymph node metastases, and had less visceral involvement. Patients in the surgery group had dramatically longer OS (median 35 vs 22 months, log-rank P=0.006). Stratified survival analysis showed that patients with bone metastasis alone or ≤3 metastasis benefit from surgery, while patients with visceral metastasis did not benefit from surgery. In multivariate analysis, surgical treatment, estrogen receptor status, progesterone receptor status and visceral metastases remained independent factors for survival. Conclusion Surgical resection of the primary site can improve survival in selected de novo stage IV breast cancer patients.

Abstract
Background As a natural compound extracted from a variety of hot peppers, capsaicin has drawn increasing attention to its anti-cancer effects against multiple human cancers including breast cancer. FBI-1 is a major proto-oncogene negatively regulating the transcription of many tumor suppressor genes, and plays a vital role in tumorigenesis and progression. However, whether FBI-1 is involved in capsaicin-induced breast cancer suppression has yet to be ascertained. This study aimed to investigate the effects of capsaicin on proliferation and apoptosis and its association with FBI-1 expression in breast cancer. Methods CCK-8 and morphological observation assay were employed to detect cell proliferation. Flow cytometry and TUNEL assay were conducted to detect cell apoptosis. RNA interference technique was used to overexpress or silence FBI-1 expression. qRT-PCR and/or Western blot analysis were applied to detect the protein expression of FBI-1, Ki-67, Bcl-2, Bax, cleaved-Caspase 3, Survivin and NF-κB p65. Xenograft model in nude mice was established to assess the in vivo effects. Results Capsaicin significantly inhibited proliferation and induced apoptosis in breast cancer in vitro and in vivo, along with decreased FBI-1, Ki-67, Bcl-2 and Survivin protein expression, increased Bax protein expression and activated Caspase 3. Furthermore, FBI-1 overexpression obviously attenuated the capsaicin-induced anti-proliferation and pro-apoptosis effect, accompanied with the above-mentioned proteins reversed, whereas FBI-1 silencing generated exactly the opposite response. In addition, as a target gene of FBI-1, NF-κB was inactivated by p65 nuclear translocation suppressed with capsaicin treatment, which was perceptibly weakened with FBI-1 overexpression or enhanced with FBI-1 silencing. Conclusion This study reveals that FBI-1 is closely involved in capsaicin-induced anti-proliferation and pro-apoptosis of breast cancer. The underlying mechanism may be related to down-regulation of FBI-1-mediated NF-κB pathway. Targeting FBI-1 with capsaicin may be a promising therapeutic strategy in patients with breast cancer.

Abstract
Latent-transforming growth factor beta-binding protein 2 (LTBP-2) is a major component of arterial and lung tissue and of the ciliary zonule, the system of extracellular fibers that centers and suspends the lens in the eye. LTBP-2 has been implicated previously in the development of extracellular microfibrils, although its exact role remains unclear. Here, we analyzed the three-dimensional structure of the ciliary zonule in wild type mice and used a knockout model to test the contribution of LTBP-2 to zonule structure and mechanical properties. In wild types, zonular fibers had diameters of 0.5-1.0 micrometers, with an outer layer of fibrillin-1-rich microfibrils and a core of fibrillin-2-rich microfibrils. LTBP-2 was present in both layers. The absence of LTBP-2 did not affect the number of fibers, their diameters, nor their coaxial organization. However, by two months of age, LTBP-2-depleted fibers began to rupture, and by six months, a fully penetrant ectopia lentis phenotype was present, as confirmed by in vivo imaging. To determine whether the seemingly normal fibers of young mice were compromised mechanically, we compared zonule stress/strain relationships of wild type and LTBP-2-deficient mice and developed a quasi-linear viscoelastic engineering model to analyze the resulting data. In the absence of LTBP-2, the ultimate tensile strength of the zonule was reduced by about 50%, and the viscoelastic behavior of the fibers was altered significantly. We developed a harmonic oscillator model to calculate the forces generated during saccadic eye movement. Model simulations suggested that mutant fibers are prone to failure during rapid rotation of the eyeball. Together, these data indicate that LTBP-2 is necessary for the strength and longevity of zonular fibers, but not necessarily for their formation.

Abstract
Purpose This study is aimed to investigate the combined treating efficacy of sodium butyrate and docetaxel on proliferation and apoptosis of the lung adenocarcinoma A549 cell line based on Gli1 regulation in vitro and in vivo. Materials and Methods RNA interference method was used to overexpress Gli1 in A549 cells. Cells were treated with varying concentrations of sodium butyrate, docetaxel or both in combination. CCK-8, colony formation assay, Hoechst 33258 staining, flow cytometry and TUNEL assay were employed to detect proliferation, cell cycle and apoptosis. qRT-PCR and Western blot analysis were applied to detect the mRNA and protein expression of Gli1. In vivo tumorigenicity was detected by tumor transplantation in nude mice. Downstream protein levels of Gli1 were detected using Western blot assay. Results It was found that sodium butyrate or docetaxel alone, respectively, inhibited proliferation and promoted apoptosis of A549 cells in vitro and in vivo, while the combination of the two generated significantly higher responses, which were also effective in another lung adenocarcinoma cell line H1299. Furthermore, the combined therapy had an additive effect in suppressing Gli1 expression and regulating the expression of its downstream proteins that involve in proliferation, cell cycle and apoptosis of A549 cells in vitro and in vivo, including decreased protein expression of Ki-67, CDK1, CDK2, Cyclin D1, Bcl-2 and Survivin, and increased protein expression of Cyclin A, p21, Bax and cleaved-Caspase 3. On the other hand, Gli1 overexpression perceptibly reversed the above-mentioned additive effect in vitro and in vivo. Conclusion This study demonstrates that the combined therapy of sodium butyrate and docetaxel additively inhibits proliferation and promotes apoptosis of A549 lung adenocarcinoma cells via suppressing Gli1 expression in vitro and in vivo. Targeting Gli1 by the combined therapy may provide new insights into the therapeutic management of patients with lung adenocarcinoma.

Abstract
Objective: To compare the clinical efficacy of transjugular intrahepatic portosystemic shunt (TIPS) with expanded polytetrafluoroethylene (ePTFE)-covered stent and drug combined with gastroscopy as the secondary prevention of esophageal-gastric variceal bleeding in portal hypertension. Methods: Patients with esophageal-gastric variceal bleeding who received TIPS treatment (ePTFE covered stent) or gastroscopy for the first time as the secondary prevention for portal hypertension at Nanfang Hospital of Southern Medical University through March to July 2017 were selected. One year after the operation, liver function changes, ascites remission rates, incidence of hepatic encephalopathy, re-bleeding rate, average hospitalization frequency and expenses, survival time, as well as the TIPS patency conditions were analyzed in the two groups of patients. 2 test, Kaplan-Meier method and Mann-Whitney U test were used to analyze the data. Results: There were 74 and 66 cases in the TIPS and the drug combined gastroscopy group and the follow-up duration (14.57 ± 0.79) was 12-16 months. One year after surgery, the remission rate of ascites in the TIPS group was higher 57.1% (32/56) than that of the drug combined gastroscopy group (0), and the difference was statistically significant (χ(2) = 2 = 36.73, P < 0.01). The cumulative incidence of hepatic encephalopathy at 1, 3, 6, and 12 months after surgery in the TIPS group was 32.4% (24/74), 37.8% (28/74), 40.5% (30/74), and 40.5% (30/74), respectively. The cumulative incidence of hepatic encephalopathy in the drug combined gastroscopy group was 3.0% (2/66), 3.0% (2/66), 3.0% (2/66), and 6.1% (4/66), respectively. Kaplan-Meier analysis showed that the cumulative incidence of hepatic encephalopathy in the TIPS group was higher than that of the drug combined gastroscopy group (χ(2) = 11.29, P < 0.01). The incidence of severe hepatic encephalopathy ( grade III to IV) at 1, 3, 6, and 12 months after surgery in the TIPS group was 2.7% (2/74), 0, 0, and 0, respectively. The incidence of severe hepatic encephalopathy in drug combined gastroscopy group was 0, and there was no statistically significant difference in development of hepatic encephalopathy between the two groups (P > 0.05). The re-bleeding rates of TIPS group and drug combined gastroscopy group were 0 and 27.3% (18/66), respectively, and the difference was statistically significant (χ(2) = 22.42, P < 0.01). There was no death reported during the follow-up period between both groups. The hospitalization frequency times (1.45 ± 0.80) in TIPS group was lower than that of the drug combined gastroscopy group times (3.24 ± 1.80), and the difference was statistically significant (U = -4.52, P < 0.01). Conclusion: In the prevention of esophageal-gastric variceal bleeding, TIPS (ePTFE-covered stent) treatment has the advantages of reducing re-bleeding rate, high ascites remission rate and hospitalizations frequency. In addition, patients treated with TIPS have a higher incidence of hepatic encephalopathy than that of drugs combined with gastroscopy. However, TIPS did not exacerbate the incidence of hepatic encephalopathy, and there was no significant difference in the 1-year survival rate after TIPS and drugs combined with gastroscopy treatment.

Abstract
Postmastectomy pain syndrome (PMPS) is a frequent complication of breast surgery, and is considered a chronic neuropathic pain in the side of surgery which persists more than 3 months. We conducted a retrospective analysis of the largest reported cohort to investigate the prevalence of PMPS and to analyze its associated risk factors as well as the influence on quality of life (QoL). Two thousand thirty-three surgically-treated female patients diagnosed between 2012 and 2017 with early-stage breast cancer were asked to complete a questionnaire survey about their current chronic neuropathic pain problems and quality of life. Multivariate logistic regression analyses were applied to determine the associated risk factors of PMPS. Results have shown that 1983 (97.5%) patients responded and completed a questionnaire survey. Among them, PMPS was found in 28.2% of patients. In univariate analysis, age≤35 years, tumor staging, history of chronic pain, total mastectomy, and axillary lymph node dissection (ALND) were significantly correlated with PMPS (P < .05). Multivariate analysis showed that age≤35 years, history of chronic pain, total mastectomy, and ALND were the independent risk factors of PMPS. QoL outcomes have shown that the global QoL score, physical function score, role function score, and social function score in the PMPS group were reduced in the PMPS group (P < .05), while the difference in emotional function score and cognitive function score showed no statistical significance (P > .05). Besides, patients with PMPS have worse body image, sexual enjoyment, and more breast symptoms. In conclusion, PMPS is linked with a high incidence among breast cancer patients, and has a considerable negative influence on the quality of life. In addition, age, total mastectomy, ALND, and history of chronic pain are the independent risk factors of PMPS.

Abstract
Two catalytic subunits of the IKK complex, IKKα and IKKβ, trigger NF-κB activation as well as NF-κB-independent signaling events under both physiological and pathological conditions. Here we identified the NF-κB-unrelated cytoprotective function of IKKα in promoting autophagy by triggering p53 transactivation and upregulation of its downstream autophagic mediator, DRAM1, in the arsenite-treated hepatoma cells, which responses depended on IKKα kinase activity. Furthermore, IKKα triggered p53/DRAM1-dependent autophagy by inducing CHK1 activation and CHK1/p53 interaction. Interestingly, after provoking autophagy, IKKα could be specifically recognized by the autophagic machinery via directly binding with LC3B, resulting in selective degradation of IKKα by autophagy. Unexpectedly, the selectivity of autophagic sequestration towards IKKα was mediated by novel mechanism independent of the classical LC3-interacting regions (LIRs) within IKKα, while C-terminal arm of LIR was involved in mediating IKKα/LC3B interaction. Taken together, we conclude that IKKα attenuates arsenite-induced apoptosis by inducing p53-dependent autophagy, and then selective feedback degradation of IKKα by autophagy contributes to the cytotoxic response induced by arsenite.

Abstract
Objective: To understand the homosexual behavior and related factors among married MSM in Mianyang city. Methods: Between January and October in 2017, a snowball sampling method was adopted to carry out cross-sectional survey through questionnaires plus HIV testing among those MSM in Mianyang city. Logistic regression model was used to analyze homosexual behaviors and related factors among married MSM under study. Statistical analysis was used by EpiData 3.1 and SPSS 19.0 software. Results: A total of 234 MSM participated in this survey. The overall rate of homosexual behavior in these married MSM appeared as 94.9% (222/234). Rate of having anal sex behavior was 94.4% (221/234) in the past 6 months, with rate of condom use as 57.9% (128/221). HIV positive rate was 8.1% (18/222). As for the motives for homosexual behavior after marriage, 87.8% (195/222) were driven by feelings of love, 12.2% (27/222) due to 'releasing pressure'. Proportion of male sex partners would include occasional sex partners (62.2%, 138/222), stable male sex partners (26.1%, 58/222) and stable boyfriends (11.7%, 26/222). Factors from logistic regression analysis showed that homosexual behaviors were related to the factors including education level of senior high school or above vs. education level of junior middle school or below (OR=3.65, 95%CI: 1.33-9.98); local residency over one year vs. the ones having local residency less than one year (OR=23.28, 95%CI:1.67-324.89); having 10 or more friends in the MSM community vs. having below 10 friends in MSM community (OR=4.15, 95%CI: 1.28-13.43); without sex pleasure with spouse vs. having sex pleasure with spouse (OR=3.25, 95%CI: 1.22-8.62); having 2 or more anal sex partners in the past 6 months vs. having less than 2 anal sex partners in the past 6 months (OR=0.28,95%CI: 0.09-0.81). Conclusions: The rate of homosexual behavior and HIV positive rate were high among MSM in Mianyang city. Homosexual behaviors after marriage were influenced by multiple factors among MSM. The motives of homosexual behavior after marriage were driven by feelings of love, the related factors were education level of senior high school or above, local residency over one year, having 10 or more friends in the MSM community and without sex pleasure with spouse. As for the motives of these behaviors was caused by releasing pressure, the related factors was having more than 2 anal sex partners.

Abstract
Objective: To investigate the early diagnosis method of pulmonary embolism in patients with skin and soft tissue defects after trauma. Methods: From January 2011 to July 2014, 5 patients with skin and soft tissue defects and pulmonary embolism after trauma were admitted to Department of Plastic Surgery and Burns of the Affiliated Drum Tower Hospital of Nanjing University Medical School, including 4 males and 1 female, aged 26-68 years. The medical records of the 5 patients were retrospectively analyzed. Hierarchical screening of patients with suspected pulmonary embolism was performed after admission for 4-45 days. Computed tomography pulmonary angiography (CTPA) was performed immediately in 2 patients who had hemodynamic disorder and were able to tolerate CTPA, and pulmonary embolism was confirmed. Clinical risk assessment was conducted for the other 3 patients who had no obvious hemodynamic disorder and only had clinical manifestations of pulmonary embolism such as chest tightness and dyspnea. Among the 3 patients, two of them were assessed as high risk possibility by clinical risk assessment and diagnosed with pulmonary embolism by CTPA immediately. The other one patient's clinical risk assessment was moderate risk possibility, but D-dimer was positive, and the patient was diagnosed with pulmonary embolism by CTPA immediately. Wound exudation of all patients was collected within 1 week after admission for microbial culture, and wound debridement and skin grafting were performed according to the wound condition. The color Doppler ultrasonography of blood vessel on lower extremity was performed to determine deep venous thrombosis of lower extremity after appearance of symptoms of pulmonary embolism. The patient was immediately given urokinase or recombinant tissue plasminogen activator by intravenous infusion for thrombolysis after definite diagnosis of pulmonary embolism. The activated partial thromboplastin time (APTT) was monitored after treatment, and standardized anticoagulation began when APTT was equal to or lower than 70 seconds. The treatment results of patients, D-dimer measurement value, bed time before definite diagnosis of pulmonary embolism, number of patients underwent wound debridement during hospitalization, definite diagnosis time of pulmonary embolism after wound debridement, and number of patients with deep venous thrombosis of lower extremity and wound infection were recorded. Results: Wounds with skin and soft tissue defects of all patients were completely healed, all skin grafts survived well, pulmonary embolism recovered well after timely treatment, and the trunk and branches of involved pulmonary artery recovered blood supply. The course of disease ranged from 1 month to 3 months. The measurement value of D-dimer was 2.4-31.7 mg/L, and the measurement values of D-dimer of 4 patients were equal to or higher than 5.0 mg/L. The bed time before definite diagnosis of pulmonary embolism was 4-46 days, with an average of 23.2 days. Four patients underwent wound debridement during hospitalization. The definite diagnosis time of pulmonary embolism after the wound debridement was 14-40 days, with an average of 20.5 days. Four patients were diagnosed with deep venous thrombosis of lower extremity. All patients had wound infection, and the bacteria causing wound infection included Pseudomonas aeruginosa of 2 cases, Staphylococcus aureus of 2 cases, and Enterococcus faecalis of 1 case. Conclusions: In the diagnosis process of pulmonary embolism in patients with skin and soft tissue defects after trauma, D-dimer positive, long-term bed rest, experiencing operation during hospitalization, and with deep vein thrombosis and wound infection can be regarded as the key points for diagnosis. When a patient has clinical symptoms of pulmonary embolism and the above conditions, the clinician should promptly perform hierarchical screening, select the corresponding examination to confirm pulmonary embolism, and immediately perform thrombolysis for the patient with pulmonary embolism according to the patient's tolerance, thereby improving patient survival rate.

Abstract
Triptolide has been indicated potent anti-cancer effect involving multiple molecular targets and signaling pathways. High-mobility group box 1 (HMGB1) is a highly conserved DNA-binding protein taking part in breast cancer development. The therapeutic effect of triptolide on HMGB1 has not been reported. Thus, our study aims to clarify the role of HMGB1 in triptolide-induced anti-growth effect on breast cancer in vitro and in vivo. We demonstrated that triptolide significantly suppressed growth of breast cancer cells by inhibition of cell viability, clonogenic ability. Further studies evidenced that triptolide treatment not only inhibited HMGB1 mRNA expression, but also decreased supernatant level of HMGB1 in vitro. In line with these observations, exogenous recombinant HMGB1 (rHMGB1) promoted cell proliferation of breast cancer, and triptolide reversed the rHMGB1-promoted proliferative effect. As well, triptolide enhanced the anti-proliferative activity of ethyl pyruvate (EP) (HMGB1 inhibitor). Furthermore, downstream correlation factors (Toll-like receptor 4 (TLR4) and phosphorylated-nuclear factor-kappaB (NF-κB) p65) of HMGB1 were significantly decreased in vitro after triptolide treatment. Consistantly, we confirmed that tumor growth was significantly inhibited after triptolide treatment in vivo. Meanwhile, immunohistochemical analyses showed that triptolide treatment significantly decreased the level of cytoplasmic HMGB1 and TLR4 expression, whereas the expression of NF-κB p65 was relatively higher in cytoplasm, and conversely lower in nucleus as compared to the control group. Collectively, these results demonstrate that triptolide suppresses the growth of breast cancer cells via reduction of HMGB1 expression in vitro and in vivo, which may provide new insights into the treament of breast cancer.

Abstract
Chinese tree shrew, an animal exhibited closer evolutionary relationship with humans compared to rodents, is getting increasingly attentions as an appealing experimental animal model for human diseases. However, a high-efficiency and stable method to establish tree shrew breast precancerous lesions model has not been clearly elucidated. Thus, the current study aimed to explore the way of establishing breast precancerous model in tree shrew and investigate the pathologic characteristics of induced breast precancerous lesions. The results indicated that 7,12-dimethylbenz(a)anthracene (DMBA) could induce breast lesions in tree shrews. However, comparing to DMBA alone, an addition of medroxyprogesterone acetate (MPA) to DMBA critically increased the rate of induced breast lesion in tree shrews. Half of induced breast lesions were intraductal papilloma and the others were atypical ductal hyperplasia. Induced lesions showed positive expression of estrogen receptor α (ERα), progesterone receptor (PR) and cytokeratin 5/6 (CK5/6), but negative expression of human epidermal growth factor receptor-2 (Her-2). The expression of B cell lymphoma-extra large (Bcl-xl) was significantly higher and the expression of B cell lymphoma 2 associated X protein (Bax) was significantly lower in the precancerous lesions (atypical ductal hyperplasia) compared to benign tumor (intraductal papilloma). These results suggest that DMBA is able to induce breast lesions in tree shrews. Combination of DMBA and MPA may be more effective to establish breast precancerous lesion tree shrew models. Tree shrew might be a promising animal model for studying the tumorogenesis of breast cancer.

Abstract
The Kunshan factory aluminum dust explosion accident in August 2nd, 2014 caused the largest number of serious burn casualties in China in the recent 30 years. With the support of the whole country and the multidisciplinary cooperation, 185 severely burned patients were rescued and treated at 20 hospitals in Jiangsu province and Shanghai with satisfactory results. The rescue and treatment of mass burn is a complicated and systematic project on account of its suddenness, uncertainty, and non-repeatability. The treatment of this explosion accident was reviewed in this paper to explore the treatment model and experience of multidisciplinary cooperation. It is worthy to ponder and explore how to face challenges and strive to improve the treatment level of mass burns.

Abstract
OBJECTIVE We previously reported that genetic ablation of (Fibroblast Growth Factors Receptors) FGFR1 in knee cartilage attenuates the degeneration of articular cartilage in adult mice, which suggests that FGFR1 is a potential targeting molecule for osteoarthritis (OA). Here, we identified R1-P1, an inhibitory peptide for FGFR1 and investigated its effect on the pathogenesis of OA in mice induced by destabilization of medial meniscus (DMM). DESIGN Binding ability between R1-P1 and FGFR1 protein was evaluated by enzyme-linked immuno sorbent assay (ELISA) and molecular docking. Alterations in cartilage were evaluated histologically. The expression levels of molecules associated with articular cartilage homeostasis and FGFR1 signaling were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR), Western blotting and immunohistochemistry (IHC). The chondrocyte apoptosis was detected by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay. RESULTS R1-P1 had highly binding affinities to human FGFR1 protein, and efficiently inhibited extracellular signal-regulated kinase (ERK)1/2 pathway in mouse primary chondrocytes. In addition, R1-P1 attenuated the IL-1β induced significant loss of proteoglycan in full-thickness cartilage tissue from human femur head. Moreover, this peptide can significantly restore the IL-1β mediated loss of proteoglycan and type II collagen (Col II) and attenuate the expression of matrix metalloproteinase-13 (MMP13) in mouse primary chondrocytes. Finally, intra-articular injection of R1-P1 remarkably attenuated the loss of proteoglycan and the destruction of articular cartilage and decreased the expressions of extracellular matrix (ECM) degrading enzymes and apoptosis in articular chondrocytes of mice underwent DMM surgery. CONCLUSIONS R1-P1, a novel inhibitory peptide for FGFR1, attenuates the degeneration of articular cartilage in adult mice, which is a potential leading molecule for the treatment of OA.

Abstract
Polymerase δ catalytic subunit gene 1 (POLD1) may serve an important function in the development of tumors. However, its role in breast cancer remains unclear. The aim of the present study was to observe the expression and the function of POLD1 in breast cancer. A total of 84 patients with invasive breast carcinoma were recruited between 2011 and 2013. The expression of POLD1 was detected in paired tumor and adjacent normal tissues. Gene expression level of POLD1 was assessed using reverse transcription quantitative polymerase chain reaction. The protein expression of POLD1 was assessed using western blot analysis. The association between the clinicopathological features of patients with breast cancer and POLD1 expression was analyzed using a χ2 test. Disease-free survival (DFS) was analyzed using Kaplan-Meier method, and Cox regression analysis was performed to investigate clinicopathological significance of POLD1 expression. Additionally, the effects of POLD1 in regulating cell cycle and proliferation of MCF-7 cells were evaluated in vitro. The results demonstrated that gene and protein expression levels of POLD1 were significantly elevated in breast cancer tissues compared with those in adjacent normal tissues. Increased expression of POLD1 was significantly associated with positive lymph node status (P=0.028), histological grade (P=0.025), p53 status (P<0.001) and ki-67 index (P=0.020). Survival analysis demonstrated that increased expression of POLD1 was associated with poor DFS (P=0.033). Additionally, increased expression of POLD1 was associated with shorter DFS at early-stage (P=0.037), late-stage cases (P=0.023) and with the presence of triple-negative tumors (TNBC; P=0.049). Multivariate analysis revealed that POLD1 may be used as an independent prognostic factor in patients with breast cancer. In vitro studies revealed that downregulation of POLD1 suppressed cell cycle progression and proliferation in MCF-7 cells. In conclusion, POLD1 may be considered as a potential prognostic marker for invasive breast carcinoma.

Abstract
Objective: To explore experience of wound treatment of extremely severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident. Methods: On August 2nd, 2014, 98 extremely severe burn mass patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to 20 hospitals in China. The patients with complete medical record were enrolled in the study and divided into microskin graft group with 56 patients and Meek skin graft group with 42 patients. Split-thickness skin in area of residual skin were resected to repair wounds of patients in microskin graft group and Meek skin graft group by microskin grafting and Meek miniature skin grafting, respectively. The residual wound size on 28 days post injury and wound infection after skin grafting of patients in the two groups, and position of donor site of all patients were retrospectively analyzed. Data were processed with t test and chi-square test. Results: The size of residual wound of patients in Meek skin graft group on 28 days post injury was (59±13)% total body surface area (TBSA), which was obviously smaller than that in microskin graft group [(70±14)%TBSA, t=4.379, P<0.05]. Twenty-nine patients in microskin graft group and 11 patients in Meek skin graft group suffered from obvious wound infection after skin grafting. Wounds of patients in two groups were repaired with residual skin around wound in head, trunk, groin, armpit, and uncommon donor sites of scrotum (4 patients), vola (10 patients), and toe or finger web (8 patients). Conclusions: Meek skin graft is the first choice for wound repair of extremely severe burn mass patients, with faster wound healing, less wound infection. Uncommon donor sites of scrotum, vola, and toe or finger web can also be used for wound repair in case of lack of skin.

Abstract
Although nipple-sparing mastectomy (NSM) is being used more frequently, the oncological safety of NSM remains unclear, particularly in young patients (<35 years). The aim of the present study was to compare the rates of local recurrence (LR), disease-free survival (DFS) and overall survival (OS) in young patients with breast cancer who had undergone NSM or conventional mastectomy (CM). The clinicopathological data of young patients with stage 0-IIB breast cancer who had undergone NSM (163 cases) or CM (194 cases) between 2007 and 2016 were retrospectively analyzed. The log-rank test was used to analyze the differences in the LR, DFS and OS rates between the two groups and multivariate analysis was used to analyze the patient prognostic factors for DFS. The median follow-up time was 49 months. Patients who had undergone CM were more likely to exhibit stage II disease (68.4 vs. 58.3%; P=0.015) and positive lymph nodes (45.9 vs. 33.1%; P=0.014). In the NSM group, LR occurred in 7 (4.3%) cases, systemic recurrence in 15 (9.2%) cases and mortality in 9 (5.5%) cases. In the CM group, LR occurred in 6 (3.1%) cases, systemic recurrence in 27 (13.9%) cases and mortality in 15 (7.7%) cases. There were no statistical differences in the LR, DFS and OS rates between the two groups (P>0.05). Following adjustment for clinical stage, the LR and DFS rates between the two groups exhibited no significant differences. Analysis of the prognostic factors demonstrated that clinical stage, lymph node status, estrogen and progesterone receptor status and human epidermal growth factor receptor 2 status were associated with DFS (P<0.05). NSM is safe for young patients with early-stage breast cancer and provides patients with an improved cosmetic outcome. Furthermore, nipple-areola complex preservation does not increase the risk of recurrence.

Abstract
Breast reconstruction after mastectomy plays an active role in improving the quality-of-life (QoL) and alleviating the psychological trauma of breast cancer patients, and has become an indispensable part of the comprehensive treatment in breast cancer. However, compared with mastectomy alone, breast reconstruction also increase operative complications. The surgical, oncological outcomes, and cosmetic effect of breast reconstruction remains to be evaluated. Data for patients with breast cancer who underwent breast reconstruction after mastectomy from February 2009 to November 2015 in our hospital were retrospectively analyzed, with a median follow-up time of 44 months. The operating time, blood loss, drainage fluid, postoperative complications, postoperative cosmesis, oncological outcomes, and QoL were evaluated and compared between different reconstruction types. A total of 151 women were included. The flap-based group had higher complication rates of marginal necrosis of incision, while the incidence of capsular contracture was higher in immediate implant group. There was no difference in blood loss, drainage fluid, and other postoperative complications. Several independent factors were associated with increased postoperative complications included diabetic, obese, and reconstruction with flap. There was no significant difference in the disease-free survival rate and overall survival rate between different surgical groups. In terms of cosmetic effect, patients in the tissue expander group were more likely to get a satisfactory postoperative breast appearance. QoL outcomes shown that the tissue expander group has better body image and sexual enjoyment, while there was no significant difference for other QoL domains. In conclusion, different methods of breast reconstruction are safe and feasible for patients with breast cancer, tissue expander implantation following delayed implant breast reconstruction is a more effective treatment on cosmetic and QoL outcomes.

Abstract
OBJECTIVES To determine the characteristics of bloodstream infections (BSIs) and to evaluate the impact of BSIs on mortality in severe burn patients. METHODS A retrospective observational study was conducted in 20 tertiary hospitals. A total of 185 patients who experienced a massive dust explosion in eastern China were included. RESULTS After exclusion, 177 patients were analysed. The median total body surface area (TBSA) burned was 95% (interquartile range 85%-98%). Inhalation injuries occurred in 97.2%. The overall 90-day mortality was 35% (62/177). During the study period, 120 (67.8%) patients developed 253 episodes of BSI with 323 unique causative pathogens. Sixty-six episodes were polymicrobial infections. Catheter-related BSIs (CRBSIs) accounted for 41.5% of the episodes. Acinetobacter baumannii (19.5%), Klebsiella pneumoniae (13.9%) and Candida (12.7%) were the most common organisms. Antimicrobial resistance was found in 63.5% of the isolates, particularly in Gram-negative bacteria. Patients who developed BSIs had a greater illness severity at admission to the intensive care unit, and worse outcomes. After adjusting for demographics, severity of illness and treatment characteristics in a multivariate logistic model, there was a trend toward BSI increasing the risk of 90-day mortality (adjusted OR 3.4; 95% CI 0.9-12.9; p=0.069). In subgroup analyses, CRBSIs (adjusted OR 5.7; 95% CI 1.3-24.9; p=0.021 versus no BSI) and polymicrobial BSIs (adjusted OR 6.1; 95% CI 1.3-28.1; p=0.020 versus no BSI) had greater risk of 90-day mortality. CONCLUSIONS A strikingly high rate of BSIs was observed in severe burn patients. Gram-negative organisms and fungi were the leading causes. CRBSIs and polymicrobial BSIs were associated with high mortality.

Abstract
Objective: To observe the effect of Toll interleukin-1 recptor homology/BB-loop mimetic hydrocinnamoyl-L-valyl pyrrolidine (AS-1) on the healing quality of deep partial-thickness scald wound in mice. Methods: Forty-two adult C57BL/6 mice were divided into sham injury group (SI), scald group (S), early AS-1 treatment group (EAT), early dimethyl sulfoxide (DMSO) control group (EDC), late AS-1 treatment group (LAT), late DMSO control group (LDC) according to the random number table, with 7 mice in each group. Mice in group SI were sham injured without other treatment. Deep partial-thickness scald model with 10% total body surface area was reproduced on the back of the other mice, and the wound was treated by daily wound cleaning with saline and dressing changing with vaseline gauze after injury. Mice in group EAT and those in group LAT were intraperitoneally injected with 20 mg/mL AS-1 50 mg/kg each day respectively from post scald hour (PSH) 8 and post scald day (PSD) 15 on. Mice in group EDC and those in group LDC were intraperitoneally injected with 20 mg/mL DMSO 50 mg/kg each day respectively from PSH 8 and PSD 15 on. On PSD 21, the gross condition of wound healing of mice with scald was observed, and the wound healing rate was calculated. Tissue samples of healed wound were collected and stained with HE and Masson respectively to observe the histomorphological change and fibrosis of collagen, and the percentage of fibrosis of collagen was calculated. The mRNA expressions of interleukin-1β (IL-1β), tumor necrosis factor α (TNF-α), transforming growth factor β1 (TGF-β1), matrix metalloproteinase-1 (MMP-1), tissue inhibitors of metalloproteinase 1 (TIMP-1), connective tissue growth factor (CTGF), type Ⅰ collagen and type Ⅲ collagen in healed wound tissue were detected by real time fluorescent quantitive reverse transcription polymerase chain reaction. The protein expressions of type Ⅰ collagen and type Ⅲ collagen in healed wound tissue were detected by Western blotting. Skin tissue of mice in group SI at the same area as that observed and collected in mice with scald was performed with the same observation and detection as mentioned above at the same time. Data were processed with one-way analysis of variance and Tukey test. Results: On PSD 21, no abnormal appearance was found in skin tissue of mice in group SI. Wounds of mice in group EAT were healed completely without scar formation, while those in the other four groups were not completely healed with scars formed in different degree. The wound healing rate of mice in group EAT was (97±4)%, close to that of group SI (100%, q=1.753, P>0.05), and both of them were obviously higher than those of groups S, EDC, LAT, and LDC [respectively (83±8)%, (87±6)%, (85±9)%, and (85±7)%, with q values from 4.819 to 6.803, P<0.05 or P<0.01]. On PSD 21, no abnormal appearance was found in morphology of skin tissue of mice in group SI. The morphology of healed wound tissue of mice in group EAT was close to that in group SI, with little epidermis hyalinosis and few newly formed collagen fibers arranged orderly. Epidermis hyalinosis in band- or flake-shape and obvious proliferation of collagen fibers arranged disorderly were observed in healed wound tissue of mice in the other four groups. Much infiltration of inflammatory cells was found in group S. The percentage of fibrosis of collagen in healed wound tissue of mice in group EAT was (30±3)%, close to that of group SI [(30±4)%, q=0.159, P>0.05], and both of them were obviously lower than those of groups S, EDC, LAT, and LDC [respectively (86±9)%, (74±5)%, (82±4)%, and (82±7)%, with q values from 12.080 to 15.530, P values below 0.01]. On PSD 21, compared with those of group SI, the mRNA expressions of IL-1β, TNF-α, TGF-β1, MMP-1, and CTGF in healed wound tissue of mice in group S, the mRNA expressions of TGF-β1 in healed wound tissue of mice in groups EDC and LDC, and the mRNA expression of MMP-1 in healed wound tissue of mice in group LAT were significantly increased (with q values from 4.039 to 5.232, P values below 0.05), while the mRNA expression of TIMP-1 in healed wound tissue of mice in group S was significantly decreased (q=4.921, P<0.05). Compared with those of group S, the mRNA expressions of IL-1β, TNF-α, TGF-β1, MMP-1, and CTGF in healed wound tissue of mice in group EAT and the mRNA expressions of IL-1β and CTGF in healed wound tissue of mice in group LAT were significantly decreased (with q values from 4.418 to 6.402, P<0.05 or P<0.01), while the mRNA expressions of TIMP-1 in healed wound tissue of mice in groups EAT and LAT were significantly increased (with q values respectively 3.929 and 8.299, P<0.05 or P<0.01). Compared with those of group SI, the mRNA and protein expressions of type Ⅲ collagen in healed wound tissue of mice in the other groups and the mRNA and protein expressions of type Ⅰ collagen in healed wound tissue of mice in groups S, EDC, LAT, and LDC were significantly increased (with q values from 7.054 to 11.650, P values below 0.01). Compared with those of group EAT, the mRNA and protein expressions of type Ⅰ collagen in healed wound tissue of mice in groups S, EDC, LAT, and LDC were significantly increased (with q values from 5.156 to 7.451, P<0.05 or P<0.01). Conclusions: AS-1 can effectively promote wound healing and reduce fibrosis degree in the early stage of inflammation response after deep partial-thickness scald in mice, which may be related to its effect in decreasing the expression of inflammation related factors IL-1β and TNF-α and fibrosis related factors TGF-β1, MMP-1, CTGF, and type Ⅰ collagen.
