Abstract
Objective: To examine whether immunohistochemistry of methylthioadenosine phosphorylase (MTAP) and p16 could be used to predict the CDKN2A status in various brain tumors. Methods: A total of 118 cases of IDH-mutant astrocytomas, 16 IDH-wildtype glioblastoma, 17 polymorphic xanthoastrocytoma (PXA) and 20 meningiomas diagnosed at Xuanwu Hospital, Capital Medical University, Beijing, China from November 2017 to October 2023 were collected and analyzed. The CDKN2A status was detected by using fluorescence in situ hybridization or next-generation sequencing. Expression of MTAP and p16 proteins was detected with immunohistochemistry. The association of loss of MTAP/p16 expression with CDKN2A homozygous/heterozygous deletion was examined. Results: Among the 118 cases of IDH-mutant astrocytoma, 13 cases showed homozygous deletion of CDKN2A. All of them had no expression of MTAP while 9 cases had no expression of p16. Among the 16 cases of IDH wild-type glioblastoma, 6 cases showed homozygous deletion of CDKN2A. All 6 cases had no expression of MTAP, while 3 of these cases had no expression of p16 expression. Among the 17 PXA cases, 4 cases showed homozygous deletion of CDKN2A, and the expression of MTAP and p16 was also absent in these 4 cases. Among the 20 cases of meningiomas, 4 cases showed homozygous deletion of CDKN2A. Their expression of MTAP and p16 was also absent. Among the four types of brain tumors, MTAP was significantly correlated with CDKN2A homozygous deletion (P<0.05), with a sensitivity of 100%. However, it was only significantly correlated with the loss of heterozygosity (LOH) of CDKN2A in astrocytomas (P<0.001). P16 was associated with CDKN2A homozygous deletion in IDH-mutant astrocytoma and PXA (P<0.001), but not with the LOH of CDKN2A. Its sensitivity and specificity were lower than that of MTAP. Conclusions: MTAP could serve as a predictive surrogate for CDKN2A homozygous deletion in adult IDH-mutant astrocytoma, PXA, adult IDH-wildtype glioblastoma and meningioma. However, p16 could only be used in the first two tumor types, and its specificity and sensitivity are lower than that of MTAP.

Abstract
Objective: To investigate the clinicopathological features, molecular genetic features, and differential diagnosis of intraductal carcinomas (IDC) of the salivary glands. Methods: Twenty-five cases of salivary gland IDC diagnosed at the Department of Oral Pathology, Shanghai Ninth People's Hospital and two cases from Department of Pathology, Henan Provincial People's Hospital, Zhengzhou, China from January 2008 to July 2023 were collected. Their clinical and pathological features were analyzed retrospectively. Fluorescence in situ hybridization and Sanger sequencing were performed. The patients were followed up and related literatures were reviewed. Results: There were 27 patients with IDC, including 15 males and 12 females, ranging in age from 20.0 to 80.0 years (mean 55.9 years). Clinically, the tumor often presented as a painless mass with a tumor diameter of 1.0-3.0 cm (mean 2.0 cm). All patients received surgical treatment. Twenty patients were followed up. One of them (1/20) died of lung cancer, while the rest survived without tumor recurrence. Histologically, IDC were classified as: intercalated (63.0%, 17/27), apocrine (25.9%, 7/27), oncocytic (7.4%, 2/27) and mixed (3.7%, 1/27) types. Intercalated tumors showed positive S-100 and negative androgen receptor (AR) immunoreactivity. Ki-67 proliferation index was low (about 1%-5%). Nine cases had the RET gene disruption, and 2 cases showed the BRAF V600E mutation. Apocrine tumors showed strong AR immunoreactivity but no S-100 immunoreactivity. Ki-67 proliferation index was high (about 10%-60%), and the RET gene rupture was detected in 1 case. Oncocytic tumors were similar to that of intercalated type in 2 cases, and RET gene disruption was detected in the both cases. Mixed tumors showed histologic features of oncocytic and apocrine patterns and harbored the RET gene disruption. Conclusions: IDC is a rare low-grade malignant tumor of the salivary gland and easily confused with other salivary gland tumors with similar morphology. Molecular testing is helpful for its differential diagnosis.

Abstract
Food allergy is an abnormal immune response triggered by food allergens, resulting in symptoms such as vomiting, diarrhea, gastroesophageal reflux, pruritus, dyspnea, and in severe cases, anaphylactic shock and mortality. The prevalence of food allergy varies within the population, with a significantly higher incidence observed among children compared to adults. This escalating trend in pediatric food allergy has emerged as a prominent concern jeopardizing children's well-being, thus prompting extensive investigations within the realm of global public health. Over the past three decades, there has been a progressive increase in the global prevalence of food allergy, accompanied by a heightened severity of allergic manifestations. Environmental factors have been identified as crucial determinants in this escalating phenomenon. Extensive research has demonstrated the pivotal role played by the environment in both the onset and progression of food allergies. The present article aims to consolidate the effects of diverse environmental factors on food allergy, elucidating their underlying mechanisms. Emphasis is placed on delineating the impact of distinct environmental factors on food allergy, thereby furnishing valuable insights for comprehending the risk factors associated with this condition. Furthermore, this comprehensive analysis contributes to the advancement of scientific strategies for the prevention and management of food allergy, promoting the development and advancement of preventive medicine.

Abstract
Objective: To investigate the clinicopathological features, immunophenotype, molecular features and differential diagnosis of primary synovial sarcoma of the lung (PSSL). Methods: Twelve cases of PSSL were collected at Henan Provincial People's Hospital, during May 2010 and April 2021, and their clinicopathological parameters were summarized. SS18-SSX, H3K27Me3, and SOX2 were added to the original immunomarkers to evaluate their diagnostic value for PSSL. Results: The age of 12 patients when diagnosed ranged from 32 to 75 years (mean of 50 years). There were 7 males and 5 females, 2 left lung cases and 10 right lung cases. Of the 6 patients who underwent surgical resection, five cases were confined to lung tissue (T1), one case had mediastinal invasion (T3), two cases had regional lymph node metastasis (N1), and none had distal metastasis. Microscopically, 11 cases showed monophasic spindle cell type and one case showed biphasic type composed of mainly epithelial cells consisting of cuboidal to columnar cells with glandular and cribriform structures. It was difficult to make the diagnosis by using the biopsy specimens. Immunohistochemistry (IHC) showed CKpan expression in 8 of 12 cases; EMA expression in 11 of 12 case; TLE1 expression in 8 of 12 cases; S-100 protein expression in two of 12 cases; various expression of bcl-2 and vimentin in 12 cases, but no expression of SOX10 and CD34 in all the cases. The Ki-67 index was 15%-30%. The expression of SS18-SSX fusion antibody was diffusely and strongly positive in all 12 cases. SOX2 was partially or diffusely expressed in 8 of 12 cases, with strong expression in the epithelial component. H3K27Me3 was absent in 3 of 12 cases. SS18 gene translocation was confirmed by fluorescence in situ hybridization (FISH) test in all 12 samples. Six cases underwent surgery and postoperative chemotherapy, while the other six cases had chemotherapy alone. Ten patients were followed up after 9-114 months, with an average of 41 months and a median of 26 months. Five patients survived and five died of the disease within two years. Conclusions: PSSL is rare and has a broad morphological spectrum. IHC and molecular tests are needed for definitive diagnosis. Compared with current commonly used IHC markers, SS18-SSX fusion antibody has better sensitivity to PSSL, which could be used as an alternative for FISH, reverse transcription-polymerase chain reaction or next generation sequencing in the diagnosis of PSSL.

Abstract
Objective: To explore the effects of advanced platelet-rich fibrin (A-PRF) on deep partial-thickness burn wounds in nude mice and its mechanism. Methods: The experimental study method was adopted. Forty healthy volunteers in Subei People's Hospital were recruited, including 32 females and 8 males, aged 60 to 72 years. Leukocyte platelet-rich fibrin (L-PRF) and A-PRF membranes were prepared after venous blood was extracted from them. The microstructure of two kinds of platelet-rich fibrin (PRF) membranes was observed by field emission scanning electron microscope. The number of samples was 3 in the following experiments. The L-PRF and A-PRF membranes were divided into L-PRF group and A-PRF group and cultured, and then the release concentrations of platelet-derived growth factor-AB (PDGF-AB) and vascular endothelial growth factor (VEGF) in culture supernatant were determined by enzyme-linked immunosorbent assay on culture day 1, 3, 7, and 14. Mice L929 fibroblasts (Fbs) were divided into L-PRF group and A-PRF group, and cultured with L-PRF or A-PRF conditioned medium, respectively. On culture day 1, 3, and 7, the cell proliferation activity was detected by thiazole blue method. The cell migration rate was detected and calculated at 24 h after scratching by scratch test. Thirty-six male BALB/c nude mice aged 6-8 weeks were selected to make a deep partial-thickness burn wound on one hind leg, and then divided into normal saline group, L-PRF group, and A-PRF group, according to the random number table, with 12 mice in each group. The wounds of nude mice in normal saline group were only washed by normal saline, while the wounds of nude mice in L-PRF group and A-PRF group were covered with the corresponding membranes in addition. The wounds of nude mice in the 3 groups were all bandaged and fixed with dressings. On treatment day 4, 7, and 14, the wound healing was observed and the wound healing rate was calculated. Masson staining was used to observe the new collagen in wound tissue, and immunohistochemical staining was used to detect the percentage of CD31 positive cells in the wound. Data were statistically analyzed with independent sample t test, analysis of variance for repeated measurement, analysis of variance for factorial design, one-way analysis of variance, and least significant difference test. Results: L-PRF membrane's dense network structure was composed of coarse fibrin bundles, with scattered white blood cells and platelets with complete morphology. A-PRF membrane's loose network structure was composed of fine fibrin bundles, with scattered small amount of deformed white blood cells and platelets. On culture day 1, the release concentration of PDGF-AB in PRF culture supernatant in A-PRF group was significantly higher than that in L-PRF group (t=5.73, P<0.05), while the release concentrations of VEGF in PRF culture supernatant in the two groups were similar (P>0.05). On culture day 3, 7, and 14, the release concentrations of PDGF-AB and VEGF in PRF culture supernatant in A-PRF group were significantly higher than those in L-PRF group (with t values of 6.93, 7.45, 5.49, 6.97, 8.97, and 13.64, respectively, P<0.05). On culture day 3, 7, and 14, the release concentrations of PDGF-AB and VEGF in PRF culture supernatant in the two groups were all significantly higher than those in the previous time points within the group (P<0.05). On culture day 1, 3, and 7, the proliferation activity of mice Fbs in A-PRF group was 0.293±0.034, 0.582±0.054, and 0.775±0.040, respectively, which were significantly stronger than 0.117±0.013, 0.390±0.036, and 0.581±0.037 in L-PRF group (with t values of 8.38, 5.14, and 6.16, respectively, P<0.05). At 24 h after scratching, the migration rate of mice Fbs in A-PRF group was (60.9±2.2)%, which was significantly higher than (39.1±2.3)% in L-PRF group (t=11.74, P<0.05). On treatment day 4, the wound exudates of nude mice in L-PRF group and A-PRF group were less with no obvious signs of infection, while the wounds of nude mice in normal saline group showed more exudation. On treatment day 7, the wounds of nude mice in L-PRF group and A-PRF group were dry and crusted, while there was still a small amount of exudate in the wounds of nude mice in normal saline group. On treatment day 14, the wounds of nude mice in A-PRF group tended to heal; a small portion of wounds remained in nude mice in L-PRF group; the wound of nude mice was still covered with eschar in normal saline group. On treatment day 4, 7, and 14, the wound healing rate and percentage of CD31 positive cells of nude mice in L-PRF group were all significantly higher than those in normal saline group (P<0.05); compared with those in normal saline group and L-PRF group, the wound healing rate of nude mice in A-PRF group was significantly increased (P<0.05), the newborn collagen was orderly and evenly distributed, with no excessive deposition, and the percentage of CD31 positive cells was significantly increased (P<0.05). Conclusions: The stable fibrin network structure of A-PRF can maintain the sustained release of growth factors, accelerate cell proliferation, and promote cell migration, so as to shorten the healing time and improve the healing quality of deep partial-thickness burn wounds in nude mice.

Abstract
Glucocorticoid-induced osteoporosis (GIOP) is a skeletal disease characterized by decreased bone strength and increased fracture risk associated with long-term glucocorticoid use. GIOP is the most common secondary osteoporosis that critically affects the quality of life of patients. Currently, the incidence of GIOP in China remains high, with insufficient awareness and lack of prevention and treatment norms. Therefore, the Chinese Rheumatology Association has established this standard based on domestic and international experience, with the aim of raising awareness of prevention and treatment among clinicians, guiding the standardized diagnosis and treatment of this disease, and improving the overall prognosis of patients with GIOP.

Abstract
Objective: To development the prognostic nomogram for malignant pleural mesothelioma (MPM). Methods: Two hundred and ten patients pathologically confirmed as MPM were enrolled in this retrospective study from 2007 to 2020 in the People's Hospital of Chuxiong Yi Autonomous Prefecture, the First and Third Affiliated Hospital of Kunming Medical University, and divided into training (n=112) and test (n=98) sets according to the admission time. The observation factors included demography, symptoms, history, clinical score and stage, blood cell and biochemistry, tumor markers, pathology and treatment. The Cox proportional risk model was used to analyze the prognostic factors of 112 patients in the training set. According to the results of multivariate Cox regression analysis, the prognostic prediction nomogram was established. C-Index and calibration curve were used to evaluate the model's discrimination and consistency in raining and test sets, respectively. Patients were stratified according to the median risk score of nomogram in the training set. Log rank test was performed to compare the survival differences between the high and low risk groups in the two sets. Results: The median overall survival (OS) of 210 MPM patients was 384 days (IQR=472 days), and the 6-month, 1-year, 2-year, and 3-year survival rates were 75.7%, 52.6%, 19.7%, and 13.0%, respectively. Cox multivariate regression analysis showed that residence (HR=2.127, 95% CI: 1.154-3.920), serum albumin (HR=1.583, 95% CI: 1.017-2.464), clinical stage (stage Ⅳ: HR=3.073, 95% CI: 1.366-6.910) and the chemotherapy (HR=0.476, 95% CI: 0.292-0.777) were independent prognostic factors for MPM patients. The C-index of the nomogram established based on the results of Cox multivariate regression analysis in the training and test sets were 0.662 and 0.613, respectively. Calibration curves for both the training and test sets showed moderate consistency between the predicted and actual survival probabilities of MPM patients at 6 months, 1 year, and 2 years. The low-risk group had better outcomes than the high-risk group in both training (P=0.001) and test (P=0.003) sets. Conclusion: The survival prediction nomogram established based on routine clinical indicators of MPM patients provides a reliable tool for prognostic prediction and risk stratification.

Abstract
Objective: To evaluate the effect of ultrasound diagnosis of thyroid micro-malignant nodules and accumulate practical experience for the management of active surveillance for them, so as to avoid overtreatment. Methods: A total of 949 patients who were diagnosed with thyroid malignant nodules using ultrasonography, with the nodules being less than 1 cm in size and without regional lymph node metastasis or distant metastasis, were included. They were treated by the same surgeon of the Department of Head and Neck Surgery, Cancer Hospital, Chinese Academy of Medical Sciences from February 2014 to December 2020. 112 patients chose immediate surgery. The rest patients were asked to accept ultrasound examination every 6 months to 1 year. Follow-up endpoints: tumor size growth of 3 mm, tumor volume increase greater than 50%, lymph node metastasis or distant metastasis. Results: The median follow-up time was 19 months. 713 patients underwent surveillance for more than 6 months. Of the 713 patients, 570 (79.9%) were women, with mean age at 43.5 years old. Tumor progression was observed in 47 (6.6%) patients with a cumulative incidence of 2.7% (1 year), 7.2% (2 years) and 9.5% (3 years). In multivariate analysis, patient age [HR=0.508, 95%CI: 0.275-0.939, P=0.031], lesion number [HR=2.945, 95%CI: 1.593-5.444, P=0.001] and tumor size [HR=2.245, 95%CI: 1.202-4.192, P=0.011] at the beginning of observation were independent risk factors for tumor progression in patients with minimal thyroid malignant nodules during follow-up. During a median (range) active surveillance of 19 (6-80) months, 74 patients chose surgery during the surveillance. Among the 186 patients who underwent surgery, only 3 patients were diagnosed with fibrotic nodules in pathology, while the rest were papillary thyroid carcinoma. The ultrasound accuracy reached 98.4%(183/186). Conclusions: Ultrasonography is an effective method of diagnosing malignant thyroid nodules. Thyroid micro-malignant nodules progress slowly. As a result, it is safe to observe them instead of taking immediate surgery. Patient age, lesion number and tumor size at the beginning of observation are independent risk factors for the tumor progression of malignant nodules.

Abstract
Objective: To explore the heterogeneity and growth factor regulatory network of dermal fibroblasts (dFbs) in mouse full-thickness skin defect wounds based on single-cell RNA sequencing. Methods: The experimental research methods were adopted. The normal skin tissue from 5 healthy 8-week-old male C57BL/6 mice (the same mouse age, sex, and strain below) was harvested, and the wound tissue of another 5 mice with full-thickness skin defect on the back was harvested on post injury day (PID) 7. The cell suspension was obtained by digesting the tissue with collagenase D and DNase Ⅰ, sequencing library was constructed using 10x Genomics platform, and single-cell RNA sequencing was performed by Illumina Novaseq6000 sequencer. The gene expression matrices of cells in the two kinds of tissue were obtained by analysis of Seurat 3.0 program of software R4.1.1, and two-dimensional tSNE plots classified by cell group, cell source, and gene labeling of major cells in skin were used for visual display. According to the existing literature and the CellMarker database searching, the expression of marker genes in the gene expression matrices of cells in the two kinds of tissue was analyzed, and each cell group was numbered and defined. The gene expression matrices and cell clustering information were introduced into CellChat 1.1.3 program of software R4.1.1 to analyze the intercellular communication in the two kinds of tissue and the intercellular communication involving vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), epidermal growth factor (EGF), and fibroblast growth factor (FGF) signal pathways in the wound tissue, the relative contribution of each pair of FGF subtypes and FGF receptor (FGFR) subtypes (hereinafter referred to as FGF ligand receptor pairs) to FGF signal network in the two kinds of tissue, and the intercellular communication in the signal pathway of FGF ligand receptor pairs with the top 2 relative contributions in the two kinds of tissue. The normal skin tissue from one healthy mouse was harvested, and the wound tissue of one mouse with full-thickness skin defect on the back was harvested on PID 7. The multiple immunofluorescence staining was performed to detect the expression and distribution of FGF7 protein and its co-localized expression with dipeptidyl peptidase 4 (DPP4), stem cell antigen 1 (SCA1), smooth muscle actin (SMA), and PDGF receptor α (PDGFRα) protein. Results: Both the normal skin tissue of healthy mice and the wound tissue of full-thickness skin defected mice on PID 7 contained 25 cell groups, but the numbers of cells in each cell group between the two kinds of tissue were different. Genes PDGFRα, platelet endothelial cell adhesion molecule 1, lymphatic endothelial hyaluronic acid receptor 1, receptor protein tyrosine phosphatase C, keratin 10, and keratin 79 all had distinct distributions on two-dimensional tSNE plots, indicating specific cell groups respectively. The 25 cell groups were numbered by C0-C24 and divided into 9 dFb subgroups and 16 non-dFb groups. dFb subgroups included C0 as interstitial progenitor cells, C5 as adipose precursor cells, and C13 as contractile muscle cells related fibroblasts, etc. Non-dFb group included C3 as neutrophils, C8 as T cells, and C18 as erythrocytes, etc. Compared with that of the normal skin tissue of healthy mice, the intercellular communication in the wound tissue of full-thickness skin defected mice on PID 7 was more and denser, and the top 3 cell groups in intercellular communication intensity were dFb subgroups C0, C1, and C2, of which all communicated with other cell groups in the wound tissue. In the wound tissue of full-thickness skin defected mice on PID 7, VEGF signals were mainly sent by the dFb subgroup C0 and received by vascular related cell groups C19 and C21, PDGF signals were mainly sent by peripheral cells C14 and received by multiple dFb subgroups, EGF signals were mainly sent by keratinocyte subgroups C9 and C11 and received by the dFb subgroup C0, and the main sender and receiver of FGF signals were the dFb subgroup C6. In the relative contribution rank of FGF ligand receptor pairs to FGF signal network in the normal skin tissue of healthy mice and the wound tissue of full-thickness skin defected mice on PID 7, FGF7-FGFR1 was the top 1, and FGF7-FGFR2 or FGF10-FGFR1 was in the second place, respectively; compared with those in the normal skin tissue, there was more intercellular communication in FGF7-FGFR1 signal pathway, while the intercellular communication in FGF7-FGFR2 and FGF10-FGFR1 signal pathways decreased slightly or did not change significantly in the wound tissue; the intercellular communication in FGF7-FGFR1 signal pathway in the wound tissue was stronger than that in FGF7-FGFR2 or FGF10-FGFR1 signal pathway; in the two kinds of tissue, FGF7 signal was mainly sent by dFb subgroups C0, C1, and C2, and received by dFb subgroups C6 and C7. Compared with that in the normal skin tissue of healthy mouse, the expression of FGF7 protein was higher in the wound tissue of full-thickness skin defected mouse on PID 7; in the normal skin tissue, FGF7 protein was mainly expressed in the skin interstitium and also expressed in the white adipose tissue near the dermis layer; in the two kinds of tissue, FGF7 protein was co-localized with DPP4 and SCA1 proteins and expressed in the skin interstitium, co-localized with PDGFRα protein and expressed in dFbs, but was not co-localized with SMA protein, with more co-localized expression of FGF7 in the wound tissue than that in the normal skin tissue. Conclusions: In the process of wound healing of mouse full-thickness skin defect wound, dFbs are highly heterogeneous, act as potential major secretory or receiving cell populations of a variety of growth factors, and have a close and complex relationship with the growth factor signal pathways. FGF7-FGFR1 signal pathway is the main FGF signal pathway in the process of wound healing, which targets and regulates multiple dFb subgroups.

Abstract
Objective: To investigate the clinicopathological features, immunophenotypic and molecular genetic characteristics and differential diagnosis of fibrous hamartoma of infancy (FHI). Methods: Thirty-three cases of surgically removed FHI were collected from the Department of Pathology, Henan Provincial People's Hospital from October 2011 to December 2020, the clinical and pathologic data with follow-up were collected and analyzed. Next-generation sequencing (NGS) and quantitative real time polymerase chain reaction (q-PCR) were used to study the molecular genetics. Results: The FHI cases occurred in 21 males and 12 females (mean age 16.7 months, range 6 months to 6 years). The sites included trunk (n=21), limb (n=11), and neck (n=1). All patients had painless solitary superficial soft tissue masses, the size was 1.5-9.0 cm (mean 3.8 cm). Microscopically, they were composed of mature adipose tissue, fibroblast/myofibroblast bundle and primitive mesenchymal cells in different proportions; giant cell fibroblastoma-like areas were seen in 14 cases. Immunohistochemistry showed variable expression of EGFR in the spindle cells and primitive mesenchymal components. In most cases, the spindle cells were positive for CD34 and SMA; giant cell fibroblastoma-like areas were strongly positive for CD34; and S-100 protein was expressed by adipocytes in all cases. Ki-67 labeling index ranged 1%-5%. There were recurrent somatic EGFR exon 20 insertion/duplication mutations in six cases tested by NGS, and there were three different mutation types: p.Asn771_His773dupAsnProHis, p.Pro772_His773insProProHis, and p.His773_Val774insThrHis. All the above 6 and another 15 tested cases showed EGFR exon 20 insertion/duplication mutations by q-PCR. Conclusions: FHI is a rare benign fibroblast/myofibroblast tumor. The characteristic histologic feature is organoid triphasic morphology, and the molecular feature is somatic mutation of EGFR exon 20 (insertion/duplication).

Abstract
Objective: To investigate the relationship between the levels of exosomes in bronchoalveolar lavage fluid (BALF) and plasma and the severity of lung injury and its outcome in patients with acute respiratory distress syndrome (ARDS). Methods: Patients who were admitted to the Department of Critical Care Medicine, Zhongda Hospital Affiliated to Southeast University and received invasive mechanical ventilation were selected from August 2020 to April 2021, and they were divided into ARDS group and non-ARDS group. Finally, 33 ARDS patients were included, including 18 males and 15 females, aged (65.5±15.5) years; 10 non-ARDS patients, 8 males and 2 females, aged (57.2±15.3) years. The BALF and plasma of the two groups of patients were collected within 24 hours after enrollment, and the total exosomes of the samples were collected by ultracentrifugation. Nanoparticle tracking analysis (NTA) was used to detect and compare the differences in exosome content between the two groups. Correlation of content with the severity and prognosis of lung injury in ARDS patients. Results: There was no significant difference in gender and age between ARDS group and non-ARDS group (both P>0.05). The exosome in plasma of ARDS group was significantly higher than that of non-ARDS group [(25.3±1.2)/ml vs (24.2±1.6)/ml, P=0.031], while the exosomes in BALF of ARDS group was also higher than that of non-ARDS group [(26.5±1.6)/ml vs (24.6±1.1)/ml, P=0.001]. The exosomes in BALF of patients with ARDS caused by intrapulmonary causes was higher than that in ARDS group caused by extrapulmonary causes [(26.9±1.5)/ml vs (25.2±0.9)/ml, P=0.01], and the infection caused by bacterial shows that the highest exosome level in BALF. The exosomes in the BALF of the mild ARDS group was significantly lower than that of the severe ARDS group [(25.7±1.3)/ml vs (27.2±1.5)/ml, P=0.038]; the exosomes in BALF of ARDS patients was negatively correlated with P/F ratio (r=-0.38, P=0.03); and it was positively correlated with Murray lung injury score (r=0.47, P=0.01). However, the static compliance levels, length of hospital stay, duration of mechanical ventilation, and 28-day outcome were not associated with the exosomes in BALF. Conclusion: Compared with non-ARDS patients, ARDS patients have significantly higher levels of exosomes in BALF and plasma, there is a certain correlation between exosomes derived from BALF and the severity of lung injury in ARDS.

Abstract
Syringopicroside is a kind of iridoid monomer compound isolated from Syringa oblata exhibiting a potent effect against hepatitis B virus (HBV). The therapeutic effect and safety of syringopicroside-loaded poly(lactic-co-glycolic acid) (PLGA) nanoparticles (SYR-NP) were studied on the model of HBV-infected ducklings and on cultured HepG2.2.15 cells. HBV DNA in ducklings was assessed by fluorescence quantitative PCR. In HepG2.2.15 cells, the content of HBsAg and HBeAg were assayed. Acute toxicity of SYR-NP was studied in ICR mice in 12 h and 7 days after SYR-NP administration. The serum levels of HBV DNA in ducklings treated with SYR-NP in a high dose was significantly lower than in the control. In HepG2.2.15 cells treated with different doses of SYR-NP, the concentrations of HBsAg and HBeAg were significantly below the control. Acute toxicity test showed high safety of SYR-NP. Thus, SYR-NP can inhibit replication of HBV DNA and protect the liver tissue.

Abstract
OBJECTIVE To investigate the clinical and immunological characteristics of overlap myositis (OM) patients. METHODS The data of 368 patients with idiopathic inflammatory myopathies (IIMs) admitted to Peking University People's Hospital from January 2004 to August 2020 were analyzed retrospectively, including demographic characteristics, clinical characteristics (including fever, Gottron' s sign/papules, Heliotrope rash, V-sign, Shawl sign, Mechanic' s hands, skin ulceration, periungual erythema, subcutaneous calcinosis, dysphagia, myalgia, myasthenia, arthritis, Raynaud' s phenomenon, interstitial lung disease, pulmonary hypertension and myocardial involvement), laboratory characteristics, immunological characteristics [including antinuclear antibodies, rheumatoid factors, myositis-associated autoantibodies (MAAs) and myositis-specific autoantibodies (MSAs)] and survival. The clinical and immunological characteristics and prognostic differences of OM and non-OM were compared. The Kaplan-Meier and Log Rank methods were used to analyze the survival. RESULTS A total of 368 patients were included. 23.9% (88/368) of IIMs patients were OM patients. Among the 88 OM patients, 85.2% (75/88) of them were female, and the median interval between disease onset and diagnosis was 13.5 months. The incidence of overlapped connective tissue diseases in the OM patients was dermatomyositis (DM) in 60.2%, polymyositis (PM) in 3.4%, immune-mediated necrotizing myopathy (IMNM) in 2.3% and anti-synthetase syndrome (ASS) in 34.1%. Compared with the non-OM patients, the proportion of the females in the OM patients was higher (85.2% vs. 72.1%, P=0.016), the OM patients had longer disease duration [13.5(4.5, 48.0) months vs. 4.0(2.0, 12.0) months, P < 0.001]. As for clinical characteristics, compared with the non-OM patients, the incidence of V-sign (25.0% vs. 44.6%, P=0.001) and periungual erythema (8.0% vs. 19.6%, P=0.013) were lower; the incidence of Raynaud's phenomenon (14.8% vs. 1.8%, P < 0.001), interstitial pneumonia (88.6% vs. 72.1%, P=0.001), pulmonary hypertension (22.7% vs. 7.5%, P < 0.001) and myocardial involvement (18.2% vs. 9.3%, P=0.033) were higher. As for immunological characteristics, compared with the non-OM patients, the incidence of elevated aspartate aminotransferase (AST) (31.8% vs. 45.0%, P=0.035) was lower and elevated C-reactive protein (CRP) (58.0% vs. 44.6%, P=0.037) was higher; the positive rates of antinuclear antibodies (ANA) (85.1% vs. 63.4%, P=0.001) and rheumatoid factors (RF) (40.2% vs. 17.8%, P < 0.001) and anti-Ro-52 (71.6% vs. 56.1%, P=0.038) in serum were higher. There was no significant difference in the survival between the OM patients and non-OM patients. CONCLUSION Pulmonary hypertension and myocardial involvement were frequently observed in OM.

Abstract
BACKGROUND Aberrant TAK1 (transforming growth factor β-activated kinase 1) activity is known to be involved in a variety of malignancies, but the regulatory mechanisms of TAK1 remain poorly understood. GRAMD4 (glucosyltransferase Rab-like GTPase activator and myotubularin domain containing 4) is a newly discovered p53-independent proapoptotic protein with an unclear role in HCC (hepatocellular carcinoma). RESULTS In this research, we found that GRAMD4 expression was lower in HCC samples, and its downregulation predicted worse prognosis for patients after surgical resection. Functionally, GRAMD4 inhibited HCC migration, invasion and metastasis. Mechanistically, GRAMD4 interacted with TAK1 to promote its protein degradation, thus, resulting in the inactivation of MAPK (Mitogen-activated protein kinase) and NF-κB pathways. Furthermore, GRAMD4 was proved to recruit ITCH (itchy E3 ubiquitin protein ligase) to promote the ubiquitination of TAK1. Moreover, high expression of TAK1 was correlated with low expression of GRAMD4 in HCC patients. CONCLUSIONS GRAMD4 inhibits the migration and metastasis of HCC, mainly by recruiting ITCH to promote the degradation of TAK1, which leads to the inactivation of MAPK and NF-κB signalling pathways.

Abstract
Objective: To investigate the clinical effect of the radical resection with a proximal incisal edge length of 20-25 mm and 30-35 mm in Siewert type Ⅱ advanced esophagogastric junction adenocarcinoma, to shorten the minimum safe distance of the proximal incisal edge to 20-25 mm. Methods: A retrospective cohort study method was used. The clinical data of 166 patients with Siewert type Ⅱ advanced esophagogastric junction adenocarcinoma who underwent total gastrectomy from January 2017 to August 2020 in the Department of Gastrointestinal Surgery, Heji Hospital Affiliated to Changzhi Medical College were retrospectively collected. According to the proximal incisal edge length, the patients were divided into two groups: the proximal incisal edge length of 20-25 mm group (69 cases) and 30-35 mm group (97 cases). The perioperative conditions and the 6-month follow-up after the operation were compared between the two groups. Results: There was no statistically significant difference in baseline information between the patients in the two groups (P>0.05). The operations of both groups were completed. The intraoperative operation time of the proximal incisal edge length of 20-25 mm group was shorter than that in the proximal incisal edge length of 30-35 mm group ((172±24)and(206±27)min, P<0.001). There were no significant differences in the amount of intraoperative blood loss, the treatment of the diaphragm during the operation and the positive rate of intraoperative freezing of the upper incisal edge between the patients in the two groups (all P>0.05). And there was no significant differences in the first exhaust time, gastric tube removal time, first feeding time and hospital stay after the operation of the two groups (all P>0.05). There was no significant differences in the incidence of anastomotic leakage, anastomotic stenosis, reflux esophagitis and intestinal obstruction after the operation between the patients in the two groups (all P>0.05). And there was no anastomotic leakage case among the 69 cases in the proximal incisal edge length of 20-25 mm group. Postoperative pathological treatment showed no significant differences in the vascular tumor thrombus and nerve infiltration between the two groups (both P>0.05). During the 6-month follow-up, there was no death or tumor recurrence in the two groups, and there was no significant difference in body weight loss at 6 months after the operation between the two groups (P=0.178). Conclusion: When radical resection of Siewert type Ⅱ advanced esophagogastric junction adenocarcinoma is performed, it is feasible to shorten the minimum safe distance of the proximal incisal edge to 20-25 mm under the premise of ensuring R0 resection. The operation time is shortened. Due to the shortening the incisal edge distance, the anastomotic tension is decreased, and the incidence of postoperative anastomotic leakage is also reduced.

Abstract
Objective: To explore the applied value of super-selective cervical lymph node dissection in papillary thyroid carcinoma (PTC) patients with clinically suspicious lateral lymph node metastasis (LNM). Methods: We retrospectively analyzed the clinical data of 232 cN1b PTC patients who underwent surgery from September 2013 to May 2018 in the Department of Head and Neck Surgical Oncology, National Cancer Center. Among them, 90 cases received super-selective neck dissection (level Ⅲ and IV) and 142 cases underwent selective neck dissection (level Ⅱ-Ⅳ). The LNM of two groups were analyzed. Results: Postoperative pathological results showed that 173 cases had LNM in the central compartment. The LNM cases of level Ⅱ-Ⅳ were 47, 147 and 130, respectively. Eight patients of super-selective neck dissection and 6 of selective neck dissection had postoperative lymphatic fistulas (P=0.146). No patients in super-selective neck dissection group while 9 patients in the selective lymph node dissection group had postoperatively permanent impairment of shoulder mobility, the difference was statistically significant (P=0.015). In the super-selective neck dissection group, 2 patients had long-term postoperative incision discomfort, and 5 cases had obvious cicatrix after surgery. In the patients with selective neck dissection, 27 cases experienced long-term incision discomfort after surgery, and 26 patients had apparent scar tissue, the differences were statistically significant (P<0.005). There was no recurrence during the follow-up. Conclusions: Super-selective neck dissection is a feasible, safe and effective treatment for cN1b PTC patients. It can improve the quality of postoperative life and avoid the over treatment for patients.

Abstract
Exosomes are a kind of membrane vesicle with a diameter of 30-150 nm. It is formed by the budding of multiple vesicles in cells, which can fuse with the cell membrane and be released into the extracellular matrix. Adipose derived stem cells (ADSCs) have the potential of self-renewal and multi-directional differentiation. They can transport the active substance, regulate the inflammatory response, cell migration, proliferation, differentiation and angiogenesis via the action of paracrine exosomes, so as to enhance the ability of wound repair, promote wound healing, and inhibit the formation of scars. Chronic wounds refer to the wounds that can not reach the anatomic and functional integrity through the normal, orderly, and timely repair process, and the course of the wound healing is more than 4 weeks. At present, there are various treatment methods for chronic wounds, among which ADSCs, although showing a good application prospect, have some limitations due to ethical issues, while exosomes can avoid this problem. This article reviews the treatment of chronic wounds with ADSC exosomes.

Abstract
Objective: To evaluate and compare the quality of life (QOL) in patients with hypopharyngeal squamous cell carcinoma after laryngeal preservation surgery and total laryngectomy. Methods: We selected parts of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and the Head and Neck Module (EORTC QLQ-C30 and EORTC QLQ-H&N35) and designed the QOL questionnaire. We investigated 42 patients with hypopharyngeal squamous cell carcinoma underwent laryngeal preservation surgery and 38 patients underwent total laryngectomy by QOL questionnaire and followed up their survival. Results: The somatic function dimension, psychological function dimension, and social function dimension of patients underwent laryngeal preservation surgery were (92.46±15.71), (80.56±22.67) and (90.08±19.50), respectively, which were higher than (79.39±32.75), (68.42±25.05) and (61.84±29.55) of the total laryngectomy group (P<0.05), while the economic dimension was not significantly different between the two groups (P>0.05). The social function dimension (including social support and socialization, family relationship) of laryngeal preservation surgery group were (89.04±25.47) for postoperative time < 70 months and (90.94±13.28) for postoperative time ≥70 months, which were higher than (65.48±29.14) and (57.35±30.32) of the total laryngectomy group (P<0.01). Conclusions: The somatic function dimension, psychological function and social function of patients with hypopharyngeal squamous cell carcinoma underwent laryngeal preservation surgery obtain a better QOL than patients underwent total laryngectomy. Therefore, we should improve the laryngeal function and QOL of patients under the premise of ensuring the survival rate.

Abstract
Objective: To explore the role and mechanism of aging pathway in patent ductus arteriosus closure of rats. Methods: Thirty outbreeding Sprague Dawley rats(20 females, 10-15 weeks old, 270-330 g) underwent random mating and conception. The primary Ductus Arteriosus smooth muscle cells (DASMCs) of pregnant 19 days(E19 group), 21 days(E21 group) and newborn(Day0 group) fetus were extracted and cultured. mRNA expression of cell senescence related markers p16, 21 and 53 genes in each group were detected by real-time fluorescent quantitative PCR(RT-PCR) after 48 hours culture. After hypoxic culture on DASMCs for 3 days, the DASMCs were divided into 3 groups: hypoxic control group(G0 group), 3 hours normal oxygen concentration treatment group(G3 group) and 6 hours normal oxygen concentration treatment group(G6 group). After intervention, mRNA expression of p16, 21 and 53 RT-PCR was detected. The DASMCs of newborn rats(Day0 group) were extracted and divided into 3 groups:low-oxygen culture control group, low-oxygen+siRNA culture group and normal oxygen concentration culture group. The DASMCs migration ability was tested experimentally by Transwell method. Result: The mRNA levels of p16, 21 and 53 in DASMCs were higher in E19 group than in Day0 group(all P<0.01), and the mRNA levels of p16, 21 and 53 in DASMCs were also higher in E21 group than those in Day0 group (all P<0.01). The mRNA levels of p16, 21 and 53 in DASMC were all higher in G0 group than those in G3 group (P<0.05 or 0.01), and the mRNA levels of p16, 21 and 53 in DASMCs were all higher in G0 group than those in G6 group (all P<0.01), and the mRNA levels of p16, 21 and 53 in DASMCs were all higher in G3 group than those in G6 group (all P<0.05). DASMCs migration ability of newborn rats was higher in normal oxygen concentration culture group than that in low-oxygen culture group (P<0.01), and DASMCs migration ability of newborn rats was also higher in low-oxygen+siRNA culture group than that in low-oxygen culture group (P<0.01). Conclusion: The expression of senescence marker of DASMCs decreases with the birth in rats during the process of ductal closure, and the aging pathway may affect ductal closure by inhibiting DASMCs migration in rats.

Abstract
Objective: To systematically evaluate the safety and efficacy of dexmedetomidine combined with ketamine during dressing changes in burn patients using meta-analysis. Methods: Foreign language databases including PubMed, Cochrane Central, Embase, and Web of Science were searched with the terms of " burns, dexmedetomidine, ketamine, and dressing" , and Chinese databases including Chinese Journal Full-Text Database, Wanfang Data, and China Academic Journal Network Publishing Database were searched with the terms in Chinese version of ",,,,," to retrieve the publicly published randomized controlled trials on the application of dexmedetomidine combined with ketamine for sedation and analgesia during dressing changes in burn patients from the establishment of each database to March 2019. The outcome indexes included systolic blood pressure at 5 minutes after administration, arousal restlessness score, ketamine dosage, dressing change time, body movement/recovery time, pain score, Ramsay sedation scores at 10 minutes after the start of dressing change and 1 hour after dressing change, physician satisfaction score, neuropsychological symptoms, nausea and vomiting times, nausea and vomiting score. RevMan 5.3 and Stata 14.0 statistical software were used to conduct a meta-analysis of eligible studies. Results: A total of 396 burn patients were included in 7 articles, including 198 patients in dexmedetomidine+ ketamine group who received dexmedetomidine and ketamine for sedation and analgesia, and 198 patients in ketamine alone group who received ketamine alone for sedation and analgesia. The bias risks of the seven studies included were uncertain. Compared with those of ketamine alone group, the systolic blood pressure at 5 minutes after administration, arousal restlessness score, nausea and vomiting score of patients in dexmedetomidine+ ketamine group were significantly decreased, with standardized mean differences of -13.89, -0.84, and -0.99 (95% confidence interval=-20.89--6.89, -1.17--0.52, -1.31--0.68, P<0.01), the Ramsay sedation score at 10 minutes after the start of dressing change and that at 1 hour after dressing change were significantly increased, with standardized mean differences of 1.53 and 0.72 (95% confidence interval=1.05-2.02, 0.13-1.31, P<0.05 or P<0.01), and the number of neuropsychological symptom and number of nausea and vomiting were significantly reduced, with relative risks of 0.20 and 0.16 (95% confidence interval=0.07-0.58, 0.05-0.58, P<0.01). The patients in the two groups were similar in ketamine dosage, dressing change time, body movement/recovery time, pain score, and physician satisfaction score. There was no publication bias in dressing change time or ketamine dosage (P>0.05), while the other indexes might have publication bias (P<0.05). Conclusions: Compared with ketamine alone, combination of dexmedetomidine and ketamine during dressing changes in burn patients can reduce the occurrence of restlessness, nausea and vomiting, neuropsychological symptoms, and other complications, better stabilize blood pressure, and enhance sedation effect.

Abstract
Objective: To investigate the expression of CD8(+)CD25(+)T cells in peripheral blood of patients with rheumatoid arthritis (RA) and its correlation with clinical indicators of rheumatoid arthritis. Methods: Peripheral blood was collected from 38 patients with RA, and 20 healthy control subjects, RA patients admitted to Peking University people's hospital from May to October 2018, and record the RA patients with the clinical manifestations and laboratory indexes, extraction in the peripheral blood lymphocytes, using flow cytometry to analyse the percentage of CD8(+)CD25(+)T cells in peripheral blood, by using the software SPASS20 and Prism6 to analyze its correlation with clinical and laboratory indices. Results: The expression of CD8(+)CD25(+)T cells in peripheral blood of RA patients was significantly increased, which was statistically different from that of healthy patients (P<0.05). CD8(+)CD25(+)T cells in peripheral blood of RA patients showed significant positive correlation with ESR(r=0.352,P=0.030), CCP(r=0.312,P=0.047) and DAS28(r=0.330,P=0.043), and negatively correlated with C3 (r=-0.354,P=0.046) and C4(r=-0.440,P=0.010).No significant correlation was found in other indicators. In RA patients, there were statistically significant differences in CD8(+)CD25(+)T cells between the low-disease active group and the high-disease active group(P<0.05), but CD8(+)CD25(+)T cells between the low-disease active group and the moderate-disease active group, or between the moderate-disease active group and the high-disease active group had no significant statistical difference. Conclusion: CD8(+)CD25(+)Tcells in peripheral blood of patients with RA are significantlyincreased, and aresignificantly correlated with laboratory and clinical indicators, which may play an important role in the pathogenesis of rheumatoid arthritis.

Abstract
Objective: To explore the correlation between Semaphorin 4D (Sema4D) and rheumatoid arthritis (RA) clinical manifestations, laboratory indexes, bone destruction and rheumatoid arthritis related interstitial lung disease(RA-ILD), and to analyze its significance in evaluating the severity of patients with rheumatoid arthritis. Methods: A total of 108 RA patients and 50 healthy controls from September 2018 to October 2019 were collected from the Department of Rheumatology and Immunology, Peking University People's Hospital and Beijing Haidian Hospital. According to the DAS 28 score, RA patients were divided into active disease group (DAS28>2.6) and stable disease group (DAS28 ≤ 2.6). Fifty healthy controls. The levels of Sema4D in serum were detected by enzyme-linked immunoassay method (ELISA), and their correlation with clinical manifestations of RA, laboratory indicators, degree of bone damage and RA-ILD were analyzed. Results: The level of serum Sema4D in RA active group was significantly higher than that in stable group and healthy control group (P<0.05). The concentration serum Sema4D was positively correlated with C-reactive protein(CRP) (r=0.28, P<0.05), rheumatoid factor(RF) (r=0.25, P<0.05) and the 28-joint disease activity score (DAS28) (r=0.45, P<0.01). The concentration serum Sema4D was positively correlated with β-Crosslaps(r=0.20, P<0.05) and Sharp-van der Heijde score (SHS)(r=0.13, P<0.05). The concentration serum Sema4D was positively correlated with Vascular endothelial growth factor (VEGF)(r=0.25, P<0.05) and Warrick score of chest CT in RA patients(r=0.27, P<0.05). The anti-cyclic citrullinated peptid(CCP) antibody, DAS28, VEGF and the incidence of RA-ILD were significantly higher than that in Sema4D negative group (P<0.05). Conclusions: Serum Sema4D level in RA patients is closely related to the disease activity, bone destruction and RA-ILD. Serum Sema4D can be used as an indicator of disease monitoring and prognosis evaluation in RA patients.

Abstract
Objective: The aim of present study is to analyze clinical and laboratory features of mixed connective tissue disease (MCTD)-associated trigeminal neuropathy (TN). Methods: Clinical records of 12 cases of MCTD complicated with TN diagnosed in Peking University People's Hospital from January 2008 to October 2019 were analyzed retrospectively. Results: The present study included 12 cases, 1 males and 11 females, average age was(40±13)years. TN was developed before the diagosis of MCTD in 1 case. TN and MCTD were occurred simutaneously in 1 case. Raynaud phenomenon (12 cases), arthritis (10cases), edema of fingers (9cases), myositis (6 cases), and pulmonary involvement (11cases) were main cinical feature of MCTD-associate TN. Antinuclear antibody (ANA) and high titer anti-U1-RNP antibody could be detected in serum of all patients. Elevated erythrocyte sedimentation rate (ESR) and creatine kinase were found in serum of 7cases and 5cases, respectively. Blink reflex tests were positive in 6 cases. Neurological symptoms improve slowly without any progress by using glucocorticoid combined immunosuppressants or intravenous gamma globulin. Conclusions: TN is often associted with actived MCTD. Positive ANA and anti-U1-RNP antibody were common in MCTD-associated TN. Blink reflex test is essential to diagnose MCTD-associated TN. Intensive treatment of MCTD contributes to control the progress of TN.

Abstract
Heracleum moellendorffii Hance is a medicinal vegetable species, and the seed dormancy of this species has caused many agricultural problems. One stratification technique involves alternating layers of seeds and substrate to allow post-ripening of dormant seeds under appropriate environmental conditions and to release dormancy. Non-stratified seeds (NS), cotyledon-stage-embryo seeds (CS) and germinated seeds (GS) represent key stages of H. moellendorffii seeds during stratification. To better understand the breaking of dormancy caused by stratification, tandem mass tag (TMT) mass spectrometry (MS)/MS was used to detect proteins among NS, CS and GS. A total of 876 proteins were identified, which were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. The results showed that carbohydrate metabolic processes, responses to stress and ribosome biogenesis were the main biological processes. The changes in protein accumulation were validated by qRT-PCR. The results showed that starch, sucrose, pyruvate and fatty acid metabolism played significant roles and that the contents of stored substances were gradually degraded during stratification. This study provides a theoretical basis in terms of proteomics for exploring the post-ripening and germination of H. moellendorffii seeds.

Abstract
To study the expression changes of inflammatory factors heme oxygenase-1 (HO-1), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) in intracerebral hemorrhage (ICH), brain tissues surrounding hematoma were collected from ICH patients. The expressions of HO-1, TNF-α, IL- 1β, and other genes were examined at different time points of ICH. Changes in HO-1, TNF-α, and IL-1β positive cell numbers after ICH were detected by immunohistochemical staining. The results showed that the expressions of HO-1, TNF-α, and IL-1β had no significant changes in brain tissues surrounding hematoma within 6 hours after ICH (P > 0.05). Their expressions during 6-24 hours and 24-72 hours after ICH increased constantly. After reaching the peak, they remained steady or slightly decreased after 72 hours. The dynamic expression changes of HO-1, TNF-α, and IL-1β were observed and their development trends were interfered timely to alleviate the secondary neurological impairment after ICH, which was significant to prevent ICH.

Abstract
Objective: To evaluate the efficacy and prognostic factors in core binding factor (CBF) acute myeloid leukemia (AML) under current therapy modalities, therefore optimizing the treatment strategies. Methods: Standard cytological and immune methods including next generation sequencing (NGS) were used for risk stratification. Complete remission (CR) rate, disease-free survival (DFS) and overall survival (OS) were assessed by multivariate Logistic and Cox regression models in a total of 206 adults (aged 16-65 years) with CBF-AML, including 152 AML patients with t(8;21) and 54 with inv(16). Results: The CR rate of inv(16) patients after first course was 54/54(100%), significantly higher than that of t(8;21) patients [127/147(86.4%), P=0.005]. The fusion transcript level and KIT mutation were independent factors related to CR rate in t(8;21) patients (P=0.044 and 0.027; respectively). DFS and OS in inv(16) patients tended to be more superior than that in t(8;21) patients (P=0.066 for DFS; P=0.306 for OS; respectively). Multivariate Cox identified negative expression of CD(19) and female gender the independent predictors of inferior DFS in t(8;21) patients (P=0.000 for CD(19); P=0.006 for sex; respectively). Analysis of combining CD(19) with gender indicated that females/CD(1)(9-)subpopulation had significantly poor DFS than did males/CD(19)(+) ones (Bonferroni-P<0.000 01). The number of mutations in each patient, FLT3-ITD and additional karyotype abnormalities did not affect CR rate and DFS (all P>0.05). Conclusions: Patients with inv(16) have better induction response than those with t(8;21). High level of fusion transcripts and positive KIT mutation are associated with low CR rate in t(8;21) patients. Negative CD(19) expression and female gender are independent predictors of inferior DFS in t(8;21) patients.

Abstract
Objective: To observe the relationship between early renal damage markers and renal ultrasonic manifestations in gout patients, and whether early renal damage is reversible after uric acid-reducing treatment. Methods: The gout patients from the Department of Rheumatology of Beijing Haidian Hospital and Peking University People's Hospital between July 2016 and December 2017 were recruited in this study. According to the results of renal ultrasonography, the patients were divided into the following three groups. Group A was normal. Group B was punctate crystallization. Group C was renal calculi. Each group included 30 patients. The patients in group B and group C who could insist on regular uric acid-reducing treatment for one year were selected. The levels of urinary RBP, β(2)-MG and NAG were measured in different groups and one year before and after uric acid-reducing treatment. Results: The urinary concentration of β(2)-MG in group A, group B and group C were (128.59±107.32), (316.08±207.41) and (311.25±162.85)mg/L, respectively. There were significant differences among the three groups (P<0.001). The urinary concentration of NAG were (13.41±5.12)U/L,(17.88±6.19)U/L and (18.48±9.84)U/L, respectively. There were differences among the three groups (P<0.01).There was no significant difference in urinary RBP concentration among the three groups (P=0.188). After one year of uric acid-reducing treatment, the levels of urinary RBP, β(2)-MG and NAG were lower than that before treatment. There were significant differences before and after treatment in each group (P<0.05). Compared with group C, the levels of urinary β(2)-MG and NAG were decreased in group B after uric acid-reducing treatment (all P<0.05). Conclusions: Renal ultrasonography is helpful for the diagnosis of early renal damage in gout patients. Early renal damage markers in gout patients decreased after uric acid-reducing treatment, suggesting that early renal damage can be reversible if early diagnosis and timely treatment can be made in gout patients.

Abstract
Objective: To evaluate the feasibility and safety of transanal lateral lymph node dissection for mid-low rectal cancer. Methods: A descriptive case series research method was used. Clinical and pathological data of 5 mid-low rectal cancer patients who underwent transanal lateral lymph node dissection at Department of Colorectal Surgery, the Sixth Affiliated Hospital of Sun Yat-sen University from November 2018 to May 2019 were retrospectively collected and analyzed. Of 5 cases, 4 were male and 1 was female with mean age of (43.2±13.2) years and mean body mass index of (21.2±2.6) kg/m(2); the mean diameter of tumor was (3.2±2.4) cm; the mean distance between tumor and anus was (6.3±2.5) cm; 3 received preoperative neoadjuvant chemotherapy. In preoperative TNM staging, 2 cases were T3N1M0, 1 was T3cN2aM0, 1 was T3cN2bM0, and 1 was T2N1M0. All the patients had no intestinal obstruction before operation. Surgical methods: (1) total mesorectal excision: using general transanal and transabdominal methods to mobilize and resect total mesorectum, and dissect No.252, No.253 lymph nodes; (2) transanal lateral lymph node dissection: dissect the adipose lymphoid tissue on the surface of the iliococcygeal muscle, the coccygeal muscle, and the obturator muscle (the No.283 lymph nodes) upward, and dissect No.263d and No.263p lymph nodes with fat tissue sequentially till the bifurcation of the internal and external iliac artery; (3) take out the specimen from anus, and make anastomosis between proximal colon and anal canal. Intraoperative and postoperative variables was observed. Results: All the 5 patients completed surgery successfully, and no patient needed to convert to open approach. The mean operative time was (295.6±97.7) minutes, and the median intraoperative blood loss was 70 (50-500) ml. The mean length of specimen was (12.9±3.0) cm, and the mean number of harvested lymph node was 30.4±9.9. The positive lateral lymph nodes were founder in 4 patients. The median distance between tumor and distal resection margin was 1.5 (1.2-8.0) cm. The resection margin in all the patients was negative. The mean time to postoperative flatus was (4.2±1.6) days, the mean postoperative spontaneous urination was (3.0±1.9) days, time to drainage tube removal was (5.6±1.9) days, and the mean postoperative hospital stay was (9.4±2.1) days. The postoperative TNM staging by pathology was 1 case with T1N0M0, 1 with T2N1M0, 1 with T3N2bM0, and 2 with T3N2M0. Five patients were moderately differentiated adenocarcinoma. Only 1 patient developed postoperative abdominal bleeding, who was healed after conservative treatment. The other 4 patients did not develop any perioperative complications, such as incision infection, presacral abscess, pelvic abscess, anastomotic leakage, or anastomotic stricture. Four patients underwent postoperative chemotherapy. All the patients were followed up for 2 to 28 weeks after surgery and they all felt well. The patients with stoma had fluent bowel. Conclusions: Transanal lateral lymph node dissection is feasible and safe in the treatment of mid-low rectal cancer, which can achieve the purpose of extended radical resection of mid-low movement rectal cancer. Moreover, this procedure is a new method to treat rectal cancer patients with lateral lymph node metastasis.

Abstract
Heterotopic ossification is a rare complication of burns, and its incidence and risk factors are still unclear. Through summarizing the literature on heterotopic ossification caused by burns at home and abroad, the author searched for the risk factors of heterotopic ossification after burn and the new progress of its prevention and treatment. It was realized that the size, depth and healing time of burn wounds were related to heterotopic ossification; the nonsteroidal anti-inflammatory drugs, radiation therapy, and their combination therapy can be used for the prevention of heterotopic ossification; surgery is an effective means of treating heterotopic ossification.

Abstract
OBJECTIVE To analyze the clinical and pathological features of small renal cell carcinoma (RCC), especially of those with diameter less than 4 cm and to understand the characteristics and factors related to recurrence and progression. METHODS A total of 200 patients with RCC were stratifiedly selected for retrospective analysis. Their baseline demographic features, tumor-specific clinical features, pathological features of renal lesions, especially microscopic features were collected. The patients were divided according to the largest diameter of renal tumor lesions. Univariate analysis was used to compare the differences between tumor staging and microscopic pathological features between the groups. Binary multivariate Logistic regression was used to investigate factors related to tumor progression and prognosis in the patients with small RCC. RESULTS The tumor diameters of 127 RCC patients were less than 4 cm and most of them had clear cell renal cell carcinoma (ccRCC). The increase in tumor diameter resulted in significantly higher T stage (P<0.01), higher WHO/International Society of Urological Pathology (ISUP) grade (P<0.05) and increasing chance of lymph node metastasis (P<0.01). Even when the tumor diameter was less than 4 cm, the patients might still have perirenal fat invasion, renal sinus invasion and greater elevated tumor grade (greater than grade 3) and synchronous lung metastasis. The incidences of intravascular thrombus (9.3% vs. 0) and tumor necrosis (27.8% vs. 5.5%) in the patients with RCC between 4-7 cm were significantly higher than those with RCC less than 4 cm (P<0.01). Sub-group analysis of small RCC (less than 4 cm) indicated that the patients with RCC between 2-4 cm were more likely to have intratumoral hemorrhage (44.7% vs. 23%, P<0.05) and necrosis than those with RCC less than 2 cm (8.2% vs. 0, P=0.095). Logistic regression analysis of small RCC showed that the incidence of tumor invasion to renal capsule was higher in ccRCC (OR=5.15, 95%CI: 1.36-19.52). Necrosis was closely related to the formation of peritumor pseudocapsule in small RCC (OR=14.90, 95%CI: 1.41-157.50). Increase in the tumor diameter was related to higher tumor grade (greater than grade 3) (OR=3.49, 95%CI: 1.11- 10.93). CONCLUSION The tumor stage and grade of small RCC (less than 4 cm) are low, but extra-renal invasion and synchronous distant metastasis may occur. Internal hemorrhage and necrosis in tumor, ccRCC subtype, along with microscopic features, such as the renal capsule invasion and perirenal pseudocapsule formation are relevant factors of malignant behavior of small RCC and could be considered in prognosis evaluation.

Abstract
Objective: There is no effective therapy for patients with advanced medullary thyroid carcinoma (MTC). Vandetanib,a novel multitargeted receptor tyrosine kinase inhibitor, has previously shown antitumor activity in phase Ⅱ studies of patients with advanced MTC. This study was to evaluate the efficacy and the safety of vandetanib on advanced MTC. Methods: This study was an open, international multi-center phase Ⅲ clinical trial and the study number was NCT01298323. The single-center study was a sub-group analysis of the international study, which was conducted on 9 pathologically confirmed advanced MTC patients by Cancer Hospital Chinese Academy of Medical Sciences between March 2012 and October 2017. Vandetanib (300 mg) was orally administered daily till death or withdrawal. The efficacy was evaluated according to RECIST criteria and the adverse events were evaluated according to NCI criteria. Results: The objective response rate was 3/9,and the disease control rate was 4/9. The median progression-free survival was 44 months. All patients who had the elevated levels of calcitonin (CTN) and carcino-embryonic antigen (CEA) before treatment began to show the decreases in the level of CTN and CEA after 3 months and later showed again the increases in the levels of both tumor markers with tumor progression. By ROC curve analysis, CTN was of statistically significance(P<0.05, 95%CI 0.558-0.834), but CEA was not(P>0.05). Adverse events were generally mild (grade 1 or 2),including hypertension (9 cases),skin rash (9 cases), and diarrhea (6 cases). Two patients developed grade 3 elevation of serum glutamate pyruvate transaminase and one patient developed grade 3 elevation of drug-related bowel disease. No grade 4 drug-related adverse event occurred. Conclusions: Vandetanib is effective and well tolerated for patients with locally advanced or metastatic MTC who have no chance for surgery. This indicates the increase of CTN is clinically relevant to disease progression, but the number of patients are extremely low, and, therefore further research is needed. Long-term use of vandetanib may cause resistance.

Abstract
A previous report has revealed that cucurbitacin B (CuB) inhibits cancer cell proliferation and tumorigenesis in non-small cell lung cancer (NSCLC) through epigenetic modifications of several genes. However, whether CuB regulates cell proliferation and apoptosis by altering methylation status of BTG3 in colorectal cancer (CRC) remains unknown. In the present study, the results showed that BTG3 was downregulated in CRC tissues compared with adjacent normal tissues. CuB significantly increased BTG3 levels, induced promoter demethylation, and decreased the levels of DNA methyltransferases (DNMT1, DNMT3a and DNMT3b) in both CRC cell lines (SW480 and Caco-2), and the effects of CuB were comparable with those of 5-Aza-dC. We also found that CuB inhibited cell proliferation, accompanied with decreased expression of Ki67. Furthermore, CuB treatment induced cell cycle arrest at G1 phase in SW480 and Caco-2 cells, as well as decreased levels of Cyclin D1 and Cyclin E1. Incubation with CuB promoted cell apoptosis in both CRC cell lines in vitro, accompanied with elevation of cleaved caspase-3 and cleaved PARP. BTG3 knockdown abolished the effects of CuB in CRC cells. In summary, CuB-induced proliferation inhibition and cell apoptosis may be due to the reactivation of BTG3 by promoter demethylation. CuB may be a promising agent for CRC therapy.

Abstract
The incidence of obstructive sleep apnea syndrome (OSAS) is rising in recent years. Since OSAS is cased by collapse of the airways, while knowledge regarding the role of the epiglottic collapse in OSAS is limited. The use of DISE has led to better understanding of the relationship between epiglottis and OSAS.In order to improve the level of diagnosis and therapeutic effect,in this paper,the clinical characteristics, diagnosis, treatment and prognosis of OSAS caused by epiglottic collapse are reviewed.

Abstract
OBJECTIVE To investigate the changes of bone mineral density (BMD) and serum bone turnover factor in newly diagnosed systemic lupus erythematous (SLE) patients. METHODS Eighty newly diagnosed SLE patients and 80 age and gender matched healthy controls were enrolled. None of the SLE patients had ever received glucocorticoid, immunosuppressive agents or vitamin D. BMD was measured at radius,lumbar spine and hip by dual X ray absorptiometry (DXA). Bone turnover markers including serum levels of tartrate-resistant acid phosphatase 5b (TRAP5b),bone alkaline phosphatase (BAP) and 25-hydroxy vitamin D3 (25-OH-VD3) were measured by enzyme-linked immunosorbent assay (ELISA). Logistic regression was employed to analyze the risk factors associated with decreased BMD. RESULTS Mean age of the SLE patients was (32.8±12.4) years, and 85% were female, none of whom were post-menopausal. BMD was significantly reduced in all the measured sites, compared with the healthy controls. Sixteen (20%) of the patients were osteopenic in at least one site measured locations. The serum levels of 25-OH-VD3 were markedly reduced in the newly diagnosed SLE patients than those of the normal controls [(46.1+12.3) nmol/L vs. (25.4+11.2) nmol/L, P<0.001)]. The serum levels of 25-OH-VD3 in the SLE patients with nephritis were much lower than those without nephritis (P=0.04). A significant negative correlation was demonstrated between the serum concentration of 25-OH-VD3 and the disease activity scores as measured by SLE disease activity index (SLEDAI) (r=-0.3,P=0.001). The serum TRAP5b concentration was positively correlated with SLEDAI (r=0.435,P=0.003). Age (P=0.058) and SLEDAI (P=0.085) were probably associated with decreased BMD in Logistic regression analysis. CONCLUSION The study showed reduced BMD in untreated SLE patients. The role of chronic inflammation was of probable importance in bone metabolism.

Abstract
OBJECTIVE To evaluate soluble interleukin-2 receptor alpha chain (sIL-2Rα, sCD25) in serum for the determination of rheumatoid arthritis (RA) activity. METHODS Peripheral blood was collected from 108 patients with RA, 39 patients with osteoarthritis (OA) and 50 healthy control subjects, and synovial fluids were from 40 patients with RA. The sera from the patients with RA, the disease control group (osteoarthritis), the healthy control group, and the synovial fluids of the RA patients were detected by enzyme-linked immunosorbent assay (ELISA).The clinical manifestations and laboratory parameters of the patients with RA were recorded and the correlation with the serum sCD25 level was analyzed. RESULTS The serum sCD25 concentration in RA group was (2 886±1 333) ng/L, the serum sCD25 concentration in OA group was (2 090±718) ng/L, and the serum sCD25 concentration in healthy group was (1 768±753) ng/L. The serum sCD25 level in the patients with RA was significantly higher than that in the disease controls and healthy controls (P<0.001). Sensitivity of serum sCD25 in the diagnosis of RA was 66.1% and specificity was 83.0%;serum sCD25 levels and erythrocyte sedimentation rate (r=0.321, P=0.001), C-reactive protein (r=0.446, P<0.001), DAS28 score (r=0.324, P<0.001), joint tenderness count (r=0.203, P=0.024), D-dimer levels (r=0.383, P<0.001), age (r=0.24, P=0.007), IgG (r=0.207, P=0.028), HRF-IgG (r=0.345, P=0.034) showed a significant positive correlation, and disease duration (r=-0.206, P=0.021) showed a negative correlation with sCD25;In patients with rheumatoid arthritis, the positive rates of serum ESR, CRP, and sCD25 were 14.3% (2 cases), 14.3% (2 cases), and 71.4% (10 cases) in the low disease activity group. The positive rates of serum ESR, CRP and sCD25 in the moderate disease activity group were 94.2% (49 cases), 82.7% (43 cases), and 86.5% (45 cases). The positive rates of serum ESR, CRP, and sCD25 in the high disease activity group were 100% (42 cases), 95.2% (40 cases), and 90.5% (38 cases);36 cases of ESR and/or CRP were negative (about 33.3%) in 108 patients, serum sCD5 levels of 17 cases in these 36 cases (about 47.2%)increased, of which 14 cases (about 82.4%) had a DAS28 score higher than 3.2. CONCLUSION The serum sCD25 has a high specificity for diagnosis of RA and a poor sensitivity. The serum level is closely related to the activity of RA, indicating that sCD25 may be involved in the inflammatory process of RA and may become a new inflammatory marker of RA. It is more meaningful for detection of serum sCD25 when RA is active, but ESR and/or CRP is negative.

Abstract
OBJECTIVE To detect the serum levels of soluble endothelial glycoprotein endoglin (s-Eng) in patients with antiphospholipid syndrome (APS) and to evaluate the correlation between s-Eng levels and clinical features and laboratory parameters. METHODS The levels of serum s-Eng were measured by enzyme linked immunosorbent assay (ELISA) in 139 patients with APS, 44 patients with SLE but no APS, 37 patients with primary Sjögren's syndrome (pSS), 23 patients with Bechet's disease (BD), 22 patients with systemic sclerosis (SSc) and 22 persistent anticardiolipin antibody (aCL) positive individuals without SLE or APS (simply aCL positive group) and 87 health controls (HC) without any auto-immune diseases. These APS patients included 64 primary APS patients and 75 APS patients secondary to SLE.The correlation between the clinical data, laboratory parameters, and serum s-Eng levels were analyzed.Independent samples t test, paired t test, Chi-square Test, Mann-Whitney U test, Pearson's χ2 test were used for statistical analyses. RESULTS (1) The serum levels of s-Eng were significantly higher in the patients with APS whether primary or secondary to SLE than in the health controls and simply aCL positive group and the patients with other autoimmune diseases, including SLE, pSS, BD and SSc (P<0.001). There was no significant difference in the serum s-Eng levels between simply aCL positive group and health controls [(5.17±2.00) mg/L vs. (5.04±1.11) mg/L, P>0.05]. (2) The best cut-off value for the diagnosis of APS was no less than 8.37 mg/L as mean ± 3SD value, with the sensitivity at 0.772 and the specificity at 0.928. The Youden index was 0.700. These results indicated good validity of s-Eng as a diagnostic marker for APS. (3) The proportions of artery thrombosis and pathological pregnancy were higher in the group of s-Eng-positive APS patients than that in s-Eng-negative group (46/81 vs. 19/58, 29/65 vs. 10/44, respectively, all P<0.05). The levels of PLT were lower in the group of s-Eng-positive APS patients (72.00×109/L vs. 119.00×109/L, P<0.001). (4) The proportions of the presence (93.83% vs. 37.93%, P<0.001) and titer (61.70 U/mL vs. 15.45 U/mL, P<0.001) of aCL were both higher in the group of s-Eng-positive APS patients than in s-Eng-negative group. The proportions of the presence (61.73% vs. 43.10%, P<0.05) and titer (33.48 U/mL vs.17.40 U/mL, P<0.05) of anti-β2-glycoprotein I antibody were both higher in the group of s-Eng-positive APS patients than in s-Eng-negative group too. CONCLUSION s-Eng serum levels were significantly increased in the patients with APS, and it may play a role as acomplementary serological marker for the diagnosis and risk prediction of APS.

Abstract
The kinetics of serum hepatitis B surface antigen (HBsAg) during the natural history of hepatitis B virus (HBV) infection has been studied, but the factors affecting them remain unclear. We aimed to investigate the factors affecting HBsAg titres, using data from multicentre, large-sized clinical trials in China. The baseline data of 1795 patients in 3 multicentre trials were studied, and the patients were classified into 3 groups: hepatitis B early antigen (HBeAg)-positive chronic HBV infection (n = 588), HBeAg-positive chronic hepatitis B (n = 596), and HBeAg-negative chronic hepatitis B (n = 611). HBsAg titres in the different phases were compared, and multiple linear progression analyses were performed to investigate the implicated factors. HBsAg titres varied significantly in different phases (P = .000), with the highest (4.60 log10 IU/mL [10%-90% confidence interval: 3.52 log10 IU/mL-4.99 log10 IU/mL]) in patients with HBeAg-positive chronic HBV infection. In all phases, age and HBV DNA were correlated with serum HBsAg level. In HBeAg-positive chronic hepatitis B patients, a negative correlation between HBsAg titres and fibrosis stage was observed. Alanine amonitransferase or necroinflammatory activity was also correlated with HBsAg titres in HBeAg-negative chronic hepatitis B patients. In conclusion, decreased HBsAg titres may be associated with advancing fibrosis in HBeAg-positive chronic hepatitis B patients or increased necroinflammation in those with HBeAg-negative chronic hepatitis B. Our findings may help clinicians better understand the kinetics of HBsAg and provide useful insights into the management of this disease.

Abstract
Multilocular prostatic cystadenoma (MPC) is a rare benign tumor that originates from the prostate itself. MPC is usually characterized by large multilocular cysts located between the rectum and bladder. The clinical presentation includes obstructive voiding symptoms, such as poor stream, intermittency, sensation of incomplete emptying, acute urinary retention and sometimes constipation symptoms due to mechanical compression of the lower intestine. Most of the previously reported patients with MPC underwent open surgery. Although the natural history of MPC remains unknown, surgical excision may not always be necessary. Here we report the case of a 49-year-old male, treated by transurethral electroresection of prostate (TURP) for prostate cyst one and half years before.His biopsy of TURP showed benign prostatic tissue with no evidence of malignancy. However, the symptoms of urinary tract obstruction were obviously aggravated after the operation. Acute urinary retention occurred intermittently 3 times. In our hospital, his total prostate specific antigen (tPSA) was 5.440 μg/L, free prostate specific antigen (fPSA) was 1.528 μg/L. After examination, it was considered as benign lesions clearly. In the operation of TURP, we found that the tumor was multilocular cystic. Histologically, the cell was mucus. Concerning the immunophenotype, CK5/6(+) , p40(+), PSA(+), P504S(+), PAX-2(-), PAX-8(-), MUC1(+), MUC5ac(+), the results of special staining were as follows: AB(+), PAS(+). At the end of the follow up 3 months later, the routine semen analysis results showed that his semen volume was 3 mL and the sperm density and sperm mobility were normal. At the end of the follow up eight months later, the patient remained free of lower urinary tract symptoms and there were no signs of recurrence. His international prostate symptom score (I-PSS) had dropped from 32 to 4, and quality of life score (QOL) had dropped from 6 to 2. MPC is a rare benign tumor originating from the prostate. TURP may aggravate the symptoms of lower urinary tract obstruction in patients with MPC, and may be temporarily observed for some asymptomatic young and middle-aged patients.

Abstract
OBJECTIVE To explore the influence of SOX10 on the proliferation and invasion of prostate cancer cells. METHODS SOX10 protein in prostate cancer cell lines PC3, DU145 and LNcap was detected by Western blotting analysis. The expression of SOX10 in prostate cancer cell lines (PC3 and DU145) were knocked down by small interfering RNAs, and the efficiency of SOX10 by small interfering RNAs was confirmed using Western blotting analysis. CCK-8 assays were conducted to assess the influences of SOX10 on the proliferation of PC3 and DU145 cells, and invasion assays were conducted to assess the influences of SOX10 on the invasion of PC3 and DU145 cells. RESULTS After SOX10 in prostate cancer cells was knocked down by small interfering RNAs, the proliferation of prostate cancer cells PC3 and DU145 was significantly inhibited. Results of CCK-8 assays showed that the absorbance of PC3 and DU145 in SOX10-silenced groups was decreased compared with those in control groups (PC3: 0 d: 0.166±0.01, 0.162±0.012 vs. 0.155 ±0.01, P>0.05; 1 d: 0.210±0.011, 0.211±0.018 vs. 0.252±0.023, P>0.05; 2 d: 0.293±0.017, 0.280±0.028 vs. 0.433±0.030, P<0.01; 3 d: 0.363±0.071, 0.411±0.038 vs. 0.754±0.045, P<0.01; 4 d: 0.592±0.065, 0.670±0.093 vs. 1.456±0.111, P<0.01. DU145: 0 d: 0.168±0.018, 0.164±0.01 vs. 0.153 ±0.012, P>0.05; 1 d: 0.218±0.007, 0.206±0.024 vs. 0.255±0.02, P>0.05; 2 d: 0.297±0.013, 0.291±0.012 vs. 0.444±0.023, P<0.05; 3 d: 0.378±0.058, 0.419±0.026 vs. 0.762±0.039, P<0.01; 4 d: 0.681±0.094, 0.618±0.050 vs. 1.419±0.170, P<0.01). Meanwhile, knocking down SOX10 significantly suppressed the invasion of prostate cancer cells PC3 and DU145. Results of invasion assays showed that the numbers of invaded cells in SOX10-silenced groups were significantly less than those in control groups (PC3: 142±38, 171±17 vs. 304±55; DU145: 96±22, 134±23 vs. 341±34, P<0.05). CONCLUSION SOX10 might promote prostate cancer progression by accelerating the ability of the proliferation and invasion of prostate cancer cells, and SOX10 might be a potential therapeutic target for prostate cancer.

Abstract
Renal angiomyolipoma (AML) is a common benign tumor in the urinary system, mainly composed of adipose tissue, blood vessels and muscle tissue. Renal AML is sporadic in most of patients, while a few are associated with tuberous sclerosis. Classical renal AML occurs predominantly in middle-aged females. Most cases are found incidentally during imaging examinations. The fat content makes AML have unique imaging characteristics and is easy to be identified with other renal tumors. However, the amount of fat varies in each tumor. AML that contains only microscopically detectable fat and whose amount of intratumoral fat may be too small to be identified on unenhanced computed tomography (CT) images is termed minimal fat or fat-poor renal AML, which appears as a high density shadow in the renal parenchyma on unenhanced CT images. Thus, it can be difficult to distinguish it from renal cell carcinoma (RCC) on imaging. Since the imaging findings are atypical, the diagnosis depends on pathological results. In addition, a few of AML can mimic malignant neoplasms. Recent studies suggested that AML might involve to peri-renal or renal sinus fat, regional lymphatics and other visceral organs, as well as inferior vena cava, which further makes the diagnosis more difficult. However, there is currently no reports about involvement of regional limphatics in minimal fat renal AML. In this article, we report a 27-year-old female patient without family history of tuberous sclerosis, who came to visit the hematologist because a high density shadow near the left kidney was found during CT scan which was accompanied by neck, armpits, groin, abdominal cavity and retroperitoneal lymph nodes enlargement. She was suspected of lymphoma in the beginning and transferred to Department of Urology to perform laparoscopic left renal mass and retroperitoneal lymph node excision and pathological examination for a definitive diagnosis. Finally, pathologic results revealed AML. Postoperative continuous lymphatic fistula developed and the retroperitoneal drainage of chylous fluid was 100-200 mL per day, lasting for 12 weeks. The fistula was successfully closed after conservative treatment including fasting and rehydration. This article summaries and discusses the diagnosis and treatment of renal AML with lymph nodes enlargement and the management of postoperative refractory lymphatic fistula by reviewing the related cases and literature.
