Abstract
Objective: To investigate the clinicopathological characteristics of primary pulmonary NUT carcinoma. Methods: A total of 7 cases of primary pulmonary NUT carcinoma were collected from Fujian Provincial Hospital (n=5), Fuzhou Taijiang Hospital (n=1) and Binzhou City People's Hospital of Shandong Province (n=1) from January 2021 to April 2023. The clinical, histopathological, and immunohistochemical features were analyzed, and NUT rearrangement were detected by fluorescence in situ hybridization (FISH) with break-apart probes. Results: Seven cases were all male with age ranging from 32 to 73 years. The main clinical manifestations were cough, expectoration and chest tightness. Microscopically, NUT carcinoma was composed of monotonous proliferation of primitive-appearing small-to-medium round cells, with few eosinophilic cytoplasm, arranged in solid sheets, nests or clusters. Abrupt keratinization was typically observed in 4 cases (4/7), with high mitotic activities and necrosis. Immunohistochemistry (IHC) showed that the tumors were positive for NUT (7/7), CK7 (4/4), CK5/6 (5/6), p40 (6/7). Ki-67 index were 30%-80%. NUT gene segregation (7/7) was detected by FISH break probes. Conclusions: Primary pulmonary NUT carcinoma is rare and highly malignant. Diagnosis depends on histopathology and IHC, with molecular detection as an adjunct for diagnosis. Pathologists should be aware of the clinicopathological characteristics to avoid misdiagnosis.

Abstract
PURPOSE/OBJECTIVE(S) To improve the accuracy of superficial dose coverage for patients undergoing modified radical mastectomy (MRM), boluses are frequently applied to the skin surface of targeted region during radiotherapy. The irregular curvature of MRM breast cases results in discrepancies of dosimetry and poor contact. Additionally, the presence of an air gap causes unnecessary high-dose escalation and uncertainty in dose calculation, making the use of commercial flat bolus problematic. This study evaluated the effectiveness of 3D-printed bolus by comparing it to commercial bolus in setup variations and dosimetric compliance through daily cone-beam computed tomography (CBCT) scans. MATERIALS/METHODS Ten patients underwent MRM were divided into 2 groups. 5 patients treated with 0.5 cm commercial bolus as group A while the other 5 patients covered by 3D Bolus as group B. 3D bolus was made of polylactic acid filament (PLA) and contoured in advance with thickness of 0.5 cm on the surface of target. Positional errors were recorded through daily image guidance and compared with the images. Both groups had right-sided breast with neck lymph nodes involved and received 50 Gy in 25 fractions using 4 partial arcs of the volumetric modulated arc therapy (VMAT) technique. The CBCTs were recalculated through treatment planning system (TPS) to assess superficial dose coverage. A two-tailed student's t-test was applied. RESULTS Groups A and B pitch angles were -0.203 ± 0.837° and 0.334 ± 0.909° (p = 0.0003). Roll angle were 0.313 ± 0.728° and -0.633 ± 1.286° (p = 0.0000013). Yaw angle were -0.034 ± 0.872° and 0.018 ± 0.883° (p = 0.721). There was a trend of differences in the Z-axis and significant statistical differences in the pitch and roll angles due to aligning gel layers directly with group A's body surface, while 3D bolus rigidly adherence to group B's delineated curve. In the planned target volume (PTV), the CI and HI of group A were 0.9448±0.0208 and 1.2061±0.0448, respectively, while 0.9776±0.0144 and 1.1472±0.0206 (p<0.005) were for group B. As for the superficial region, which is defined from body surface to 0.5cm inside PTV, CI and HI of A were 0.8290±0.0599 and 1.4675±0.2434, while for B, they were 0.9753±0.0214 and 1.1330±0.0126, respectively (p<0.005). CONCLUSION The study analyzed the results through image comparison and investigated the CI and HI between two types of boluses. The 3D bolus reduces setup errors and improves dose coverage especially when superficial region is concerned. Better consistency of patient repositioning and dosimetry can be achieved and proved by daily assessment of CBCT scan. The customization of 3D bolus with integration of TPS and CT scans provides a solution to the inadequacies of commercial bolus. The results suggest that the use of 3D bolus is a promising development in radiation therapy for MRM breast cancer patients.

Abstract
Objective: To investigate the clinicopathologic and molecular genetic characteristics of myxoid pleomorphic liposarcoma (MPLPS). Methods: Six cases of MPLPS diagnosed and consulted in Fujian Provincial Hospital from 2015 to 2021 were collected for histomorphological observation, immunohistochemistry, and fluorescence in situ hybridization (FISH) detection of DDIT3 (CHOP) gene translocation and MDM2/CDK4 gene amplification. Results: There were four males and two females, aged 26-74 years (mean 53.8 years). The tumor size was 3.8-16.0 cm (mean 11.8 cm). All six cases had similar histopathologic features, showing overlapping histologic morphology of myxoid liposarcoma and pleomorphic liposarcoma. Four cases (4/6) were positive for S-100 protein, and the Ki-67 index was 50%-95%. All cases (6/6) were negative for DDIT3 (CHOP) translocation and MDM2/CDK4 amplification by FISH. TP53 (p.R248w) germline mutation was found in one case. Conclusions: MPLPS is a rare subtype of liposarcoma, characterized by overlapping morphology of myxoid liposarcoma and pleomorphic liposarcoma. Genetically, a few of them have TP53 gene germline mutations, but they lack of DDIT3 (CHOP) translocation or MDM2/CDK4 amplification.

Abstract
Background Implementation of adjuvant therapies in non-metastatic melanoma improved treatment outcomes in some patients; however, adjuvant therapy can be associated with significant cost and risk of toxicity. Therefore, there is an unmet need to better identify patients at high risk of recurrence. Patients and methods We carried out an ultrasensitive droplet digital PCR (ddPCR)-based detection of BRAFV600E-mutated circulating tumor DNA (ctDNA) from blood samples prospectively collected before surgery, 1 hour after surgery, and then serially during follow-up. Results In 80 patients (stages ≤III), BRAFV600E mutations were detected in 47.2% of tissue, in 37.7% of ctDNA samples collected before surgery, and in 25.9% of ctDNA samples collected 1 hour after surgery. Patients with detected ctDNA in blood collected 1 hour after surgery compared to patients without detected ctDNA had higher likelihood of melanoma recurrence (P < 0.001) and shorter median disease-free survival (P = 0.001) and overall survival (P = 0.003). Conclusions Ultrasensitive ddPCR can detect ctDNA in pre- and post-surgical blood samples from patients with resectable melanoma. Detection of ctDNA in post-surgical samples is associated with inferior treatment outcomes. Ultrasensitive ddPCR can detect ctDNA in pre- and post-surgical samples. Detection of ctDNA 1 hour after surgery is associated with inferior treatment outcomes. There were no associations between ctDNA detection at other timepoints and clinical outcomes.

Abstract
Background Oncogenic mutations in PIK3CA are prevalent in diverse cancers and can be targeted with inhibitors of the phosphoinositide-3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway. Analysis of circulating tumor DNA (ctDNA) provides a minimally invasive approach to detect clinically actionable PIK3CA mutations. Patients and methods We analyzed PIK3CA hotspot mutation frequency by droplet digital PCR (QX 200; BioRad) using 16 ng of unamplified plasma-derived cell-free DNA from 68 patients with advanced solid tumors (breast cancer, n = 41; colorectal cancer, n = 13; other tumor types, n = 14). Results quantified as variant allele frequencies (VAFs) were compared with previous testing of archival tumor tissue and with patient outcomes. Results Of 68 patients, 58 (85%) had PIK3CA mutations in tumor tissue and 43 (74%) PIK3CA mutations in ctDNA with an overall concordance of 72% (49/68, κ = 0.38). In a subset analysis, which excluded samples from 26 patients known not to have disease progression at the time of sample collection, we found an overall concordance of 91% (38/42; κ = 0.74). PIK3CA-mutated ctDNA VAF of ≤8.5% (5% trimmed mean) showed a longer median survival compared with patients with a higher VAF (15.9 versus 9.4 months; 95% confidence interval 6.7-17.1 months; P = 0.014). Longitudinal analysis of ctDNA in 18 patients with serial plasma collections (range 2-22 time points, median 5) showed that those with a decrease in PIK3CA VAF had a longer time to treatment failure (TTF) compared with patients with an increase or no change (10.7 versus 2.6 months; P = 0.048). Conclusions Detection of PIK3CA mutations in ctDNA is concordant with testing of archival tumor tissue. Low quantity of PIK3CA-mutant ctDNA is associated with longer survival and a decrease in PIK3CA-mutant ctDNA on therapy is associated with longer TTF. Testing for PIK3CA mutations in ctDNA is concordant with testing of tumor tissue. High PIK3CA-mutant abundance in ctDNA was associated with shorter survival. Increasing PIK3CA-mutant abundance in serial blood samples was associated with shorter TTF. Longitudinal monitoring of PIK3CA-mutant ctDNA tracked with cancer clinical course.

Methods: This observational study belongs to cluster sampling cases, which included the clinical data from children with airway allergic diseases in Allergy Department and Otorhinolaryngology Department of Beijing Children's Hospital from April to December in 2015. They were followed up every three months during 12 months. All the subjects were required to continuously record daily symptom by diary card. ACT/c-ACT, VAS, treatment steps to control asthma, respiratory infections, wheeze, pulmonary function(FEV1%pred,FEV1/FVC,PEF%pred,FEF25%pred,FEF50%pred,FEF75%pred,MMEF%pred), FeNO were assessed in every visiting. The mean±standard deviation was used for the measurement data in accordance with normal distribution. Comparing the pulmonary function indexes at every point, the measurement data with normal distribution and uniform variance were analyzed by single factor analysis of variance, and the measurement data with uneven variance were tested by non-parametric rank sum test. Results: Among 147 recruited participants, 106 completed the combined diagnosis and management. The airway allergic diseases control rate was 87.7% at 12 months after the combined diagnosis and management. At every point, the average daily symptom score and VAS score which were significantly lower than at the baseline(H=35.854,P=0.000)[ 1.2(0.7,2.2),0.6(0.2,1.5),0.4(0.1,1.0),0.5(0.1,1.1) vs 2.0(1.0,3.5)],(H=39.559,P=0.000)[2.5(0.5,4.7),2.2(0.3,4.4),1.8(0.2,4.6),1.6(0.3,3.8) vs 6.9(4.1,9.8)]. ACT/c-ACT score at 3, 6, 9, 12 months were significantly higher than at the baseline (H=79.695,P=0.000) [25.0(22.5,27.0),26.0(24.0,27.0),25.0(23.0,27.0),25.0(24.0,27.0) vs 20.0(17.0,22.0)]. FEV1%pred and FEF25%pred at 3, 6 months were significantly higher than at the baseline (F=3.563,P=0.007)(104.7±12.6 vs 96.8±14.5,103.0±10.3 vs 96.8±14.5),(F=2.456,P=0.046)(96.6±22.0 vs 85.0±21.9,93.3±18.0 vs 85.0±21.9). PEF%pred at 3, 6, 9, 12 months after the combined diagnosis and management were significantly higher than at the baseline(F=5.497,P=0.000)(105.1±18.1,101.2±15.3,99.7±17.1,99.8±17.5 vs 90.3±17.8). FeNO at 3, 6, 9, 12 months respectively were no significantly differences at the baseline(F=0.751,P=0.558)(25.7±23.6 vs 30.7±25.6,25.9±16.5 vs 30.7±25.6,27.5±20.2 vs 30.7±25.6,30.6±19.6 vs 30.7±25.6).The respiratory infections rate were 69.8%(74/106),67.0%(71/106),60.4%(64/106),51.9%(55/106) at 3, 6, 9, 12 months respectively.

Abstract
Objective: To analyze the pathogenesis, clinical manifestations, diagnosis, treatment and prognosis of pulmonary malignant perivascular epithelioid cell tumor (PEComa) with adenocarcinoma. Methods: In August 2020, the Department of Pathology, Dongguan People's Hospital of Southern Medical University, diagnosed a case of pulmonary malignant PEComa mixed with adenocarcinoma. The clinical data, pathological diagnosis, treatment plan and prognosis of the patient were analyzed, and the literature was reviewed. Firstly, "malignant perivascular epithelioid cell tumor"+" Pulmonary "+"adenocarcinoma" was used to search CNKI and Wanfang Medical Database, but no relevant reports were found. Then, we changed the search term as "pulmonary malignant perivascular epithelioid cell tumor", and search for PubMed, Embase, Web of Science and Cochrane by combining the subject terms with "pulmonary malignant perivascular epithelioid cell tumor" and "PEComa" as subtopics. The language was Chinese or English and the search deadline was November 2020. Results: The patient, a 46-year-old male, was admitted to the hospital on August 20, 2020, due to "repeated cough and chest pain for more than 10 days, accompanied by rapid weight loss". Serology detected increased expression of lung non-small cell lung cancer related antigens. PET-CT showed a large mass of soft tissue density in the left thoracic cavity with an SUV value of 22.8. The postoperative pathological diagnosis was malignant PEComa mixed with adenocarcinoma and the lymph nodes were metastasized. Due to the detection of EGFR sensitive mutation, postoperative chemotherapy and targeted therapy were administered, and the current state was stable. A total of 12 cases of pulmonary malignant PEComa were retrieved in the literature, which were common in middle-aged and elderly people. They usually presented with cough or chest tightness. Chest CT mostly showed round masses with clear boundaries, and 8 cases had metastasis to mediastinal lymph nodes and other organs. Conclusions: Pulmonary malignant PEComa is rare. It is the first report of the same mass with lung primary adenocarcinoma. The tumor progresses rapidly. Complete surgical resection of the lesion and lymph node dissection are more appropriate treatment strategies, supplemented by postoperative chemotherapy and targeted therapy. For cases diagnosed as pulmonary PEComa, long term follow-up should be performed, even if the pathological diagnosis is benign.

Abstract
Objective: To investigate the clinicopathological features, differential diagnosis and molecular characteristics of clear cell renal cell carcinoma (ccRCC) with hemangioblastoma component (ccRCC-HBc). Methods: Two ccRCC-HBc cases diagnosed at Fujian Provincial Hospital in September 2015 and March 2016, respectively, were included. Their morphological, immunohistochemical and molecular features were analyzed, including fluorescence in situ hybridization (FISH) detection of TFE3, TFEB and VHL genes. Related literature was reviewed to reveal the characteristics of this tumor. Results: The two cases occurred in 2 women, aged 33 and 66 years, respectively. The maximum diameters of the tumors were 4.0 cm and 8.5 cm, respectively. Histologically, the ccRCC component, representing approximate 10%-20% of the neoplasm, while the tumor cells arranged in flaky, nested, and solid distribution. The tumor cells had conspicuous nucleoli, with rich thin-wall capillary network in the stroma. The hemangioblastoma-like component, representing approximate 60%-70% of the neoplasm, showed a rich capillary network of single-layered flat endothelial cells enclosing stromal cells. The latter cell type showed a pale or eosinophilic cytoplasm exhibiting occasional lipid droplets. Rare cell nuclei appeared enlarged, pleomorphic, or bizarre. The two components were intermingled with each other. Immunohistochemically, the tumor cells were positive for PAX8, CKpan, EMA, vimentin, CD10, RCC, CAⅨ, and P504s in ccRCC area; in another area, the tumor cells were positive for α-inhibin, CD34 and vimentin, while CD10 were weakly positive. Neither TFE3 or TFEB gene split signal was detected in the 2 cases (0/2), nor was VHL gene mutation in case 2 (0/1). Conclusion: ccRCC-HBc is an extremely rare entity of ccRCC. The diagnosis is mainly based on clinical and pathological characteristics, as well as immunohistochemistry. Molecular pathology is helpful for its differential diagnosis. The primary approach of treating ccRCC-HBc is complete surgical excision and chemotherapy. The targeted treatment is helpful if possible.

Abstract
Objective: To explore the molecular features and prognostic value of RAS mutations in patients with myelodysplastic syndromes (MDS) . Methods: 112-gene targeted sequencing was conducted to detect RAS mutations in 776 patients with newly diagnosed primary MDS from December 2011 to December 2018. The mutual exclusivity and co-occurrence in gene mutations and clonal architecture were explored. Moreover, the prognostic significance of RAS mutations in MDS was analyzed. Results: RAS gene mutations were found in 52 (6.7% ) cases, 38 (4.9% ) of whom harbored NRAS mutation, 18 (2.3% ) KRAS mutation, and 4 (0.5% ) both NRAS and KRAS mutations. All the NRAS mutations and 65% of the KRAS mutations were located in codons 12, 13, and 61. PTPN11, FLT3, U2AF1, RUNX1, WT1, ETV6, and NPM1 mutations were enriched in patients with RAS mutations (Q<0.05) . Around 80% of RAS mutations represented subclonal lesions in patients who harbored at least two different mutations. Patients with RAS mutations were more frequently diagnosed with MDS with excess blast (MDS-EB) (82.7% vs. 35.2% , P<0.001) and had higher levels of white blood cell count (4.33×10(9)/L vs. 2.71×10(9)/L, P<0.001) , neutrophil absolute count (2.13×10(9)/L vs. 1.12×10(9)/L, P<0.001) , and bone marrow blast percentage (7% vs. 2% , P<0.001) but lower levels of platelet count (48×10(9)/L vs. 62×10(9)/L, P=0.048) . RAS mutations were correlated with higher-risk categories in the Revised International Prognostic Scoring System (IPSS-R) (71.1% vs. 37.9% , P<0.001) . The median overall survival of patients with NRAS mutations was shorter than the others (P=0.011) , while the significance was lost in the multivariable model. Conclusion: RAS gene mutations always occurred in the late-stage MDS and co-occurred with other signal transduction- and transcription factor-related gene mutations. PTPN11, a RAS pathway-related gene, is an independent poor prognostic factor in MDS patients.

Abstract
Objective: To investigate the clinicopathologic features, differential diagnosis, immunohistochemical profiles and molecular characteristics of primary extraskeletal osteosarcoma (ESOS). Methods: Ten cases of ESOS diagnosed and treated in Fujian Provincial Hospital, Fuzhou, China from January 2003 to January 2019 were collected and subjected to immunohistochemical staining and molecular analyses. The patients were followed up by telephone interview. Relative literature was also reviewed to assess the characteristics of this tumor. Results: The ten cases occurred in 3 women and 7 men, aged from 36 to 85 years (median, 60 years). The sizes of these tumors ranged from 5.5 to 17.5 cm (median, 11.0 cm). Histologically, at low magnification, the tumors were nodular, leafy and lobulated. They were composed of spindle cells, neoplastic osteoid cells, and cartilage tissues, with unequally-proportional mixture of these components. The three components intermingled with each other. Immunohistochemistry profiling showed that the tumor cells were positive for SATB2 (9/9), while α-SMA (4/10) and EMA (1/10) stains were focally positive. Ki-67 proliferation index was 10%‒50%. Desmin, CD68, S-100 protein, SOX10, HMB45, CD117, DOG1, CD34, CKpan, GATA3 and PAX8 stains were negative. MDM2/CDK4 gene amplification signals were not detected in the 6 cases (0/6), which were subjected to the FISH. The SSX18 break-apart signal and the C-KIT and PDGFR-α mutations were not detected (0/5 and 0/3, respectively). Conclusions: Primary ESOS is an extra-osseous osteogenic tumor. The diagnosis is mainly dependent on clinical, radiological and pathological characteristics. Immunohistochemistry and molecular profiling are helpful for making the correct diagnosis.

Abstract
Objective: To investigate the clinicopathological characteristics, immunophenotype, molecular genetic characteristics and prognosis of the metaplastic thymoma (MT). Methods: The clinicopathological and follow-up data of five MT cases were collected at Fujian Provincial Hospital from 2008 to 2019. Immunohistochemical staining and MAML2 gene detection were performed, and the relevant literature was reviewed. Results: There were 2 males and 3 females, aged 36-64 years (mean age 52 years). The tumors ranged 3.2-7.3 cm in the greatest diameter (average 5.1 cm).Microscopically, the tumor showed a biphasic pattern with epithelial cells merging gradually with the spindle cell component. The two areas transited to each other or had obvious boundary. Both components showed mild atypia. No mitosis was observed in either area, and a small number of lymphocytes were observed in the stroma. Immunohistochemical staining showed that epithelioid cells were positive for CKpan, p63 and E-cadherin. Spindle cells were positive for vimentin and EMA, while the Ki-67 index was less than 5%, and lymphocytes were negative for TdT. MAML2 gene apart signal was detected in two of the cases (2/4) that were tested by FISH. Conclusions: MT is a low-grade malignant epithelioid thymic tumor. Its diagnosis and differential diagnosis are dependent on the morphological characteristics, immunohistochemical staining and MAML2 gene detection. The primary treatment option is surgical resection, with an overall good prognosis.

Objective: To investigate the clinicopathological features, diagnosis, differential diagnosis, and molecular alterations of malignant gastrointestinal neuroectodermal tumor (MGNET). Methods: Four cases of MGNET were collected at Fujian Provincial Hospital, from July 2013 to January 2019. H&E and immunohistochemical staining were retrospectively evaluated, together with genetic mutation analysis of EWSR1. The relevant literature was systematically reviewed. Results: There were two male and two female patients, with an age range of 34-81 (median 57) years. Tumor sizes ranged from 5-9 (median 6.8) cm. Microscopy showed diffuse and flaky growth of tumor cells, some of which were small and round. The tumor cells were arranged in solid, flaky, nested or pseudoadenoid patterns. The tumor cells were epithelioid, oval, short spindled, or small, with round or oval nuclei. The cytoplasm was eosinophilic or clear. Osteoclast-like multinucleated giant cells were scattered focally. Mitosis was about (2-10)/10 HPF. Immunohistochemically, the tumor cells were positive for S-100 protein (4/4), SOX10 (4/4), Syn (2/4), INI1 (4/4), H3K27Me3 (4/4) and vimentin (4/4). Ki-67 index was 15%-90%. Gene mutation detection confirmed EWSR1 mutation in all four cases, and C-KIT/PDGFRα genes were not mutated in two cases. Conclusions: MGNET is a rare high grade malignant soft tissue tumor. The diagnosis is based on clinicopathological, immunophenotypic, and molecular pathology features. The primary treatment for MGNET is complete surgical excision and chemotherapy; the prognosis is poor.

Abstract
Objective: To explore the features and clinical significance of gene mutations in patients with myelodysplastic syndromes with ring sideroblasts (MDS-RS) . Methods: A total of 255 newly diagnosed primary MDS-RS patients were retrospectively reviewed from our center from January2001 to June 2019. SF3B1 gene mutations were detected by Sanger sequencing in 129 patients, and next generation sequencing (NGS) was performed in the other 126 patients using a set of selected 112-genes. Results: A total of 193 (75.7%) patients presented with SF3B1 mutation, predominantly mutant at amino acid position 700 (K700E) (n=147, 76.2%) . Non-SF3B1 gene mutations were TET2 (16.7%) , ASXL1 (14.3%) , U2AF1 (11.1%) , TP53 (7.9%) , SETBP1 (6.3%) , and RUNX1 (6.3%) . RS 5%-<15% patients had a higher SETBP1 mutation frequency than RS≥15% patients (21.4% vs 4.5%, P=0.044) . Mutation frequencies of other genes were similar in both groups (all P>0.05) . SF3B1 variant allele frequencies (VAF) had positive correlation with marrow RS percentage but without statistical significance in RS 5%-<15% group (P=0.078, r=0.486) . SF3B1 mutant patients presented with higher marrow RS percentage compared with wild-type patients[40.0% (15.0%-80.0%) vs 25.5% (15.0%-82.0%) , P<0.001], and SF3B1 VAF positively correlated with RS percentage (P=0.009, rs=0.261) in RS≥15% group. Age, ANC, PLT, mean RBC corpuscular volume, RS percentage, IPSS-R cytogenetics, and IPSS-R risk score were significantly different between patients with SF3B1 mutations and wild-type SF3B1 (all P<0.05) . Multivariable survival analyses adjusted by age and IPSS-R cytogenetics revealed that SF3B1 mutation was an independent favorable prognostic factor (HR=0.265, 95% CI 0.077-0.917, P=0.036) , and TP53 mutation was an adverse variable independent of SF3B1 mutation (HR=6.272, 95% CI 1.725-22.809, P=0.005) . According to the mutant status of SF3B1 and TP53, MDS-RS patients were categorized into 4 groups, namely, with SF3B1 and TP53 mutation, with wild-type SF3B1 and TP53, with wild-type SF3B1 but TP53 mutation, and with SF3B1 mutation but wild-type TP53. There was a significant difference for OS among these 4 groups (P<0.001) . The former 3 groups showed no significant difference in OS in multiple comparisons. However, the SF3B1 mutation but wild-type TP53 group had a better OS than wild-type SF3B1 but TP53 mutation group and wild-type SF3B1 and TP53 group, whereas a similar OS compared with SF3B1 and TP53 mutation group. Conclusion: SF3B1 mutations were prevalent in MDS-RS patients with the most common mutation at amino acid position 700 (K700E) . SF3B1 mutation was an independent favorable prognostic variable, whereas TP53 mutation was an independent adverse variable. SF3B1 mutation could coordinate with TP53 mutation for more sophisticated prognosis stratification in MDS-RS patients.

Abstract
Objective: To investigate the clinicopathological features, diagnosis, differential diagnosis and immunohistochemical (IHC) characteristics of paraganglioma of urinary bladder (PUB). Methods: The clinical and pathological data of 23 cases of PUB were collected at the Second Affiliated Hospital of Fujian Medical University (7 cases); Fujian Provincial Hospital (8 cases); Fujian Medical University Union Hospital (6 cases); and First Affiliated Hospital of Fujian Medical University (2 cases) from May 2010 to November 2018. IHC staining for CK, GATA3, CD56, Syn, CgA, S-100 protein, HMB45, SDHB, OCT3/4 and Ki-67 was done using EliVision method; and the relevant literature was reviewed. Results: There were 14 women and 9 men, aged ranged from 21 to 73 years (median 51 years). Clinically, patients presented with headache, vertigo, palpitation, hypertensive crisis during micturition, hypertension, blurred vision, gross hematuria and paroxysmal pallor. The tumor sizes ranged from 0.9 to 6 cm (mean2.5 cm). Macroscopically, most tumors were exophytic and well delineated within the lamina propria or muscularis propria. The tumors were firm and nodular and showed grayish-tan cut surface. Histologically,the tumor growth pattern was expansive or showed interpenetrating infiltrative growth within the lamina propria or muscularis propria; the tumor cells were typically arranged in distinctive nests (Zellballen) with organoid arrangement; pseudo-rosette were seen in some cases. The cells were rounded or polygonal and had rich, acidophilic or amphophilic cytoplasm and may contain pigmented granules and vacuoles; the nuclei were central or eccentric, with small nucleoli, although occasionally some nuclei were pleomorphic and hyperchromatic. Spindled sustentacular cells could be seen around the nests of tumor cells in some cases. There were abundant vessels that were fissure-like, hemangioma-like or dilated. By IHC, the tumor cells were positive for GATA3 (2/23), OCT3/4 (2/23), CD56 (22/23), Syn (23/23), CgA (22/23), S-100 (sustentacular cell, 23/23) and SDHB (23/23); and negative for CK and HMB45; Ki-67 index was 1%-5%. At follow-up, there was no recurrence or metastasis in 18 cases. Conclusions: The diagnosis of PUB relies on the morphologic and IHC features; but there may be histomorphologic heterogeneity. The most important differential diagnosis is invasive urothelial carcinoma. The tumor cells may show aberrant cytoplasmic expression of OCT3/4; there is no clear correlation between SDHB and OCT3/4 expression in the group.

Abstract
Objective: To investigate the incidence and risk factors of lower extremities deep venous thrombosis (DVT) in patients with chronic refractory wounds (chronic wounds). Methods: A retrospective analysis of 722 cases of chronic wounds admitted to the First People's Hospital of Zhengzhou from January 1, 2015 to December 31, 2018 was carried out, and clinical data such as gender, age, wound involves the lower extremities, wound type, duration of wound, D-dimer level and complicated diabetes, hypertension, coronary heart disease, cerebral infarction, pneumonia and sepsis/septic shock were collected. The patients were divided into DVT group and non-DVT group according to the color ultrasound test. Multivariate binary logistic regression analysis was used to screen the independent risk factors of DVT in patients with chronic wounds. Results: There were 55 (7.6%) patients in DVT group, of which 44(80.0%) were diagnosed as chronic DVT by conventional lower extremities venous color ultrasound screening at admission, and the remaining 11(20.0%) were newly diagnosed during hospitalization. There were no significant differences in gender, wound involves the lower extremities, duration of wound, complicated diabetes and hypertension between DVT group and non-DVT group (all P>0.05); and the differences were statistically significant in age, wound type, D-dimer level, complicated coronary heart disease, cerebral infarction, pneumonia and sepsis/septic shock (all P<0.05). Multivariate binary logistic regression analysis showed age [OR=2.260 (95%CI: 1.584-3.224)], D-dimer level [OR=14.201 (95%CI: 6.101-33.055)], complicated coronary heart disease [OR=2.731 (95%CI: 1.210-6.162)] and sepsis/septic shock [OR=3.170 (95%CI: 1.115-9.016)] were independent risk factors for DVT (all P<0.05). Conclusion: Chronic wounds patients have a higher incidence of DVT, most of which are chronic DVT, and age, D-dimer level, complicated coronary heart disease and sepsis/septic shock are independent risk factors for DVT in chronic wounds.

Abstract
目的 探讨平均红细胞体积(MCV)对骨髓增生异常综合征(MDS)预后的影响。 方法 收集2009年12月至2017年12月我中心新诊断、无红细胞输注史的321例原发性MDS患者,回顾性分析MCV水平对整体及不同骨髓原始细胞水平患者总生存(OS)期的影响。 结果 全部患者按照MCV水平高低分为MCV≤100 fl组(148例)和MCV>100 fl组(173例)。MCV≤100 fl组患者中位OS时间为27(95%CI 19~35)个月,MCV>100 fl组患者中位OS时间为72(95%CI 5~139)个月,差异有统计学意义(P<0.001)。亚组分析示,在骨髓原始细胞<5%的患者中,MCV≤100 fl患者的中位OS期较MCV>100 fl者显著缩短(P=0.002);而在骨髓原始细胞≥5%的患者中,MCV水平对OS的影响不显著(P=0.078)。在纳入其余临床指标及基因突变校正后,MCV≤100 fl仍为骨髓原始细胞<5%患者的独立不良预后因素(HR=1.890,95%CI 1.007~3.548,P=0.048)。对不同MCV水平骨髓原始细胞<5%的MDS患者的临床及实验室指标进行分析,结果显示MCV≤100 fl组患者外周血HGB高于MCV>100 fl组[90(42~153)g/L对78.5(28~146)g/L,P=0.015],IPSS-R高危/极高危组比例及IPSS-R染色体核型分组差/很差比例明显高于MCV>100 fl组,差异有统计学意义(28.8%对10.8%,P=0.003;24.7%对12.9%,P=0.049)。MCV≤100 fl组患者平均基因突变数目较MCV>100 fl组多(0.988个对0.769个,P=0.064),SF3B1突变较MCV>100 fl组少见(4.7%对15.4%,P=0.018)。 结论 MCV≤100 fl为骨髓原始细胞<5%的MDS患者独立于基因突变及其他临床指标的预后不良因素。

Abstract
Objective: To explore the clinical effects of antibiotic bone cement in the treatment of diabetic foot ulcers. Methods: According to the treatment methods, 18 patients with diabetic foot ulcers (11 males and 7 females, aged 53-79 years), who were conformed to the study criteria and admitted to our hospital from January 2016 to January 2017, were enrolled in traditional group; 18 patients with diabetic foot ulcers (11 males and 7 females, aged 55-80 years), who were conformed to the study criteria and admitted to our hospital from February 2017 to February 2018, were enrolled in bone cement group. Wounds of patients in traditional group were treated with vacuum sealing drainage after conventional debridement. Wounds of patients in bone cement group were covered with antibiotic bone cement after conventional debridement. The number of patients with positive bacterial culture in wound exudate in the 2 groups on admission and 3, 6, 9, and 15 days after surgery, the length of hospital stay, the number of operation, and the wound complete healing time were retrospectively recorded. Data were processed with Fisher's exact probability test and independent sample t test. Results: Compared with (29±10) d and (4.6±1.2) times of patients in traditional group, the length of hospital stay [(9±3) d] of patients was obviously shortened, the number of operation [(1.3±0.6) times] of patients was obviously reduced, the number of patients with positive bacterial culture in wound exudate at each time point post surgery was obviously reduced (t=8.177, 9.896, P<0.05 or P<0.01) in bone cement group. There were no statistically significant differences in the number of patients with positive bacterial culture in wound exudate on admission and wound complete healing time between patients in the 2 groups (t=0.175, P>0.05). Conclusions: The antibiotic bone cement treatment of diabetic foot ulcers can reduce the number of patients with positive bacterial culture in wound exudate and the number of operation, as well as shorten the length of hospital stay.

Abstract
目的 探讨伴TP53基因异常骨髓增生异常综合征(MDS)患者的临床特征及预后。 方法 回顾性分析2009年10月至2017年12月中国医学科学院血液病医院新诊断的584例原发性MDS患者临床资料,采用包含112个血液肿瘤相关基因的靶向测序技术进行突变分析,并采用间期荧光原位杂交(FISH)技术检测TP53基因缺失。分析TP53基因突变和(或)缺失与临床特征之间的关系及其对患者总生存(OS)的影响。 结果 42例(7.2%)伴TP53基因异常,其中单纯基因突变31例(5.3%),单纯基因缺失8例(1.4%),同时伴有突变和缺失3例(0.5%)。34例伴TP53基因突变患者中共检测到37个TP53突变,其中35个位于DNA结合结构域(第5~8号外显子),1个位于第10号外显子,1个为剪切位点突变。伴TP53基因异常组的平均基因突变数目(2.52个)显著高于无异常组(1.96个)(z=−2.418,P=0.016)。伴TP53基因异常患者的中位年龄[60(21~78)岁]高于无异常患者[52(14~83)岁](z=−2.188,P=0.029);伴TP53基因异常组中复杂核型比例、IPSS较高危组(中危-2及高危)比例显著高于无异常组(P值均<0.001)。伴TP53基因异常组的中位OS期[13(95%CI 7.57~18.43)个月]较无异常组(未达到)显著缩短(χ2=12.342,P<0.001),但多因素模型纳入复杂核型进行校正后,TP53突变不再是独立预后因素。 结论 伴TP53基因异常MDS患者中基因突变较基因缺失常见,突变位点主要分布于DNA结合结构域。TP53基因异常与复杂核型相关,且常与多个基因突变相伴出现。在多因素模型纳入复杂核型校正后,TP53基因异常则不再是独立的预后因素。

Abstract
Background Targeted methylation sequencing of plasma cell-free DNA (cfDNA) has a potential to expand liquid biopsies to patients with tumors without detectable oncogenic alterations, which can be potentially useful in early diagnosis. Patients and methods We developed a comprehensive methylation sequencing assay targeting 9223 CpG sites consistently hypermethylated according to The Cancer Genome Atlas. Next, we carried out a clinical validation of our method using plasma cfDNA samples from 78 patients with advanced colorectal cancer, non-small-cell lung cancer (NSCLC), breast cancer or melanoma and compared results with patients' outcomes. Results Median methylation scores in plasma cfDNA samples from patients on therapy were lower than from patients off therapy (4.74 versus 85.29; P = 0.001). Of 68 plasma samples from patients off therapy, methylation scores detected the presence of cancer in 57 (83.8%), and methylation-based signatures accurately classified the underlying cancer type in 45 (78.9%) of these. Methylation scores were most accurate in detecting colorectal cancer (96.3%), followed by breast cancer (91.7%), melanoma (81.8%) and NSCLC (61.1%), and most accurate in classifying the underlying cancer type in colorectal cancer (88.5%), followed by NSCLC (81.8%), breast cancer (72.7%) and melanoma (55.6%). Low methylation scores versus high were associated with longer survival (10.4 versus 4.4 months, P < 0.001) and longer time-to-treatment failure (2.8 versus 1.6 months, P = 0.016). Conclusions Comprehensive targeted methylation sequencing of 9223 CpG sites in plasma cfDNA from patients with common advanced cancers detects the presence of cancer and underlying cancer type with high accuracy. Methylation scores in plasma cfDNA correspond with treatment outcomes.

Abstract
Objective: To observe effects of exogenous high mobility group protein box 1 (HMGB1) on angiogenesis in ischemic zone of early scald wounds of rats. Methods: Thirty-six Sprague-Dawley rats were divided into HMGB1 group and simple scald (SS) group according to the random number table, with 18 rats in each group. Comb-like copper mould was placed on the back of rats for 20 s after being immersed in 100 ℃ hot water for 3 to 5 min to make three ischemic zones of wound. Immediately after scald, rats in HMGB1 group were subcutaneously injected with 0.4 μg HMGB1 and 0.1 mL phosphate buffer solution (PBS), and rats in SS group were subcutaneously injected with 0.1 mL PBS from boarders of ischemic zone of scald wound. At post scald hour (PSH) 24, 48, and 72, 6 rats in each group were collected. Protein expressions of vascular endothelial growth factor (VEGF) in ischemic zone of wound at PSH 24, 48, and 72 and protein expressions of CD31 in ischemic zone of wound at PSH 48 and 72 were detected by immunohistochemistry. The number of microvessel in CD31 immunohistochemical sections of ischemic zone of wound at PSH 48 and 72 was calculated after observing by the microscope. The mRNA expressions of VEGF and CD31 in ischemic zone of wound were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction at PSH 24, 48, and 72. Data were processed with analysis of variance of factorial design, t test, and Bonferroni correction. Results: (1) At PSH 24, 48, and 72, protein expressions of VEGF in ischemic zone of wound of rats in HMGB1 group were significantly higher than those of rats in SS group (t=7.496, 4.437, 5.402, P<0.05 or P<0.01). At PSH 48 and 72, protein expressions of CD31 in ischemic zone of wound of rats in HMGB1 group were 0.038 8±0.007 9 and 0.057 7±0.001 2 respectively, significantly higher than 0.013 4±0.004 9 and 0.030 3±0.004 0 of rats in SS group (t=10.257, 15.055, P<0.01). (2) At PSH 48 and 72, the number of microvessel in ischemic zone of wound of rats in HMGB1 group was obviously more than that of rats in SS group (t=3.536, 4.000, P<0.05). (3) At PSH 24, 48, and 72, mRNA expressions of VEGF in ischemic zone of wound of rats in HMGB1 group were significantly higher than those of rats in SS group (t=4.406, 3.821, 3.356, P<0.05). At PSH 24 and 48, mRNA expressions of CD31 in ischemic zone of wound of rats in HMGB1 group were significantly higher than those of rats in SS group (t=4.113, 3.466, P<0.05). At PSH 72, mRNA expressions of CD31 in ischemic zone of wound of rats in 2 groups were close (t=0.010, P>0.05). Conclusions: Exogenous HMGB1 can promote angiogenesis in ischemic zone of early scald wounds of rats by increasing expressions of VEGF and CD31.

Abstract
Objective: To investigate the clinicopathological features, differential diagnosis, and genetic alteration of Langerhans cell sarcoma (LCS). Methods: Four cases of LCS were collected from Fujian Provincial Hospital and Fuzhou General Hospital of Nanjing Military Command of PLA from July 2013 to January 2017. Clinicopathological features and immunophenotype were retrospectively reviewed in four LCS cases combined with genetic mutation analysis of BRAF and ALK. Results: Four cases included 2 women and 2 men with ages from 42 to 79 years (median=59.3 years). The size of the tumors ranged from 2.5-7.8 cm. Histologically, at the low power field, the tumors consisted of highly cellular proliferation in fascicules, whirlpool and diffuse sheets arrangement. The tumor cells were kidney-or horseshoe-shaped to round epithelioid cells or enlarged spindle cells. The neoplastic cells showed cytological atypia, hyperchromatic nuclei with prominent 1 to 2 nucleoli. Multinucleated giant cells were also found. Mitotic activity was approximately (50-70) mitoses/10 HPF. Immunohistochemically, the tumor cells were positive for S-100 protein (4/4), SOX10(3/4), Langerin/CD207(4/4), CD1a(3/4), CD68(3/4), CD163(3/4), and INI-1(4/4). Ki-67 index was 30%-80%. Gene mutation analysis showed that one case had BRAF V600E mutation but none had ALK gene alteration. Conclusions: LCS is a rare tumor with highly malignant potential and distinct morphologic features.The primary treatment for LCS is completely surgical excision and chemotherapy. The prognosis is generally poor.

Abstract
Objective: To study the characteristics of gene mutations in Chinese myelodysplastic syndromes (MDS) patients. Methods: A total of 511 Chinese patients with MDS performed 112-gene targeted sequencing were retrospectively analyzed. Results: Eighty-three distinct mutant genes were found in 511 patients with MDS. Amongst these, the most frequent mutations was associated with epigenetics (50%) , followed by spliceosome (37%) , signal transduction (34%) , transcription factors (24%) and cell cycle/apoptosis (17%) . 439 subjects (86%) had at least one gene mutation. The mean number of mutations in refractory anemia with unilineage dysplasia (RCUD) was 1.25, refractory anemia with multilineage dysplasia (RCMD) was 1.73, refractory anemia with ring sideroblasts (RARS) was 2.79, refractory anemia with excess blasts-1 (RAEB-1) was 2.22, RAEB-2 was 2.34, MDS with isolated 5q- was 2.67, MDS, unclassified (MDS-U) was 2.00. U2AF1 mutant subjects were more likely to have isolated+8[Q<0.001, OR=4.42 (95% CI 2.23-8.68) ]and less likely to have complex karyotypes[Q=0.005, OR=0.22 (95% CI 0.04-0.72) ]. According to the number of gene mutations, all subjects were categorized into three groups, namely group with 0-1 mutation, with 2 mutations and with three or more mutations. There was a significant difference in overall survival (OS) among three groups (P=0.041) . Conclusion: About 90% patients with MDS have at least one gene mutation. Genes associated with epigenetics and spliceosome are most common mutated genes in MDS. The increased numbers of gene mutations accompany with disease evolution and associate with poor prognosis.

Abstract
Objective: To observe the deposition of complement C3d at different development stages in human normal organs and tissues, and investigate the significance of its deposition. Methods: Using immunohistochemical methods, the deposition of C3d was detected at different development stages of 60 normal human organs and tissue specimens and double staining was performed in some specimens. Ninty-five cases of other organs or tissues were collected as control group. Results: In 50 of 60 livers, it was observed the deposition of C3d in Glisson's capsule and periportal sheath, with irregular linear network-like disposition surrounding the portal sheath. In different age groups, the expression of C3d was more beyond the 20 year-old group than 3 to 20 year-old group. There wasn't any expression of C3d under 3-year-old group. Under the immuning electron micrograph, C3d depositing at the Glisson's capsule was observed, without immuning compounding. Thirty in 40 spleens, deposition of C3d in capsules, arteries of lymphatic sheath, follicles in the spleen was observed. Conclusions: The deposition of C3d in Glisson's capsule, splenic trabeculae, fibrous sheath, endarterium of liver and spleen arterioles, within normal human tissues from patients elder than 3 years, are osmosis/immunogenic deposition. The deposition of C3d is a normal physiological phenomenon, and treatment of the deposition of C3d should be avoided, as it is an immune complex or immuning reaction phenomenon.

Abstract
Background Cell-free DNA (cfDNA) from plasma offers easily obtainable material for KRAS mutation analysis. Novel, multiplex, and accurate diagnostic systems using small amounts of DNA are needed to further the use of plasma cfDNA testing in personalized therapy. Patients and methods Samples of 16 ng of unamplified plasma cfDNA from 121 patients with diverse progressing advanced cancers were tested with a KRASG12/G13 multiplex assay to detect the seven most common mutations in the hotspot of exon 2 using droplet digital polymerase chain reaction (ddPCR). The results were retrospectively compared to mutation analysis of archival primary or metastatic tumor tissue obtained at different points of clinical care. Results Eighty-eight patients (73%) had KRASG12/G13 mutations in archival tumor specimens collected on average 18.5 months before plasma analysis, and 78 patients (64%) had KRASG12/G13 mutations in plasma cfDNA samples. The two methods had initial overall agreement in 103 (85%) patients (kappa, 0.66; ddPCR sensitivity, 84%; ddPCR specificity, 88%). Of the 18 discordant cases, 12 (67%) were resolved by increasing the amount of cfDNA, using mutation-specific probes, or re-testing the tumor tissue, yielding overall agreement in 115 patients (95%; kappa 0.87; ddPCR sensitivity, 96%; ddPCR specificity, 94%). The presence of ≥ 6.2% of KRASG12/G13 cfDNA in the wild-type background was associated with shorter survival (P = 0.001). Conclusion(s) Multiplex detection of KRASG12/G13 mutations in a small amount of unamplified plasma cfDNA using ddPCR has good sensitivity and specificity and good concordance with conventional clinical mutation testing of archival specimens. A higher percentage of mutant KRASG12/G13 in cfDNA corresponded with shorter survival.

Abstract
OBJECTIVE To evaluate the effect and safety of a modified Prolift procedure, without preceding partial trachelectomy or hysterectomy for pelvic organ prolapse (POP) with coexistent cervical elongation. METHODS Clinical data of 72 patients that underwent a modified Prolift procedure for POP with coexistent cervical elongation, between December 2008 and June 2012 in Fuzhou General Hospital of Nanjing Military Command was retrospectively analysed. A comparison was carried out between preoperative and postoperative parameters of pelvic organ prolapse quantitation system (POP-Q), and an objective evaluation was made according to the overall cure rate and recurrence rate. Pelvic floor distress inventory-short form 20 (PFDI-20) was used to investigate the subjective cure rate and improvement of symptoms. RESULTS Patients were followed up at median 52 months (36-78 months). One bladder perforation and one rectum perforation occurred during the procedure. Four patients (6%, 4/72) had uterine prolapse at 9-19 months after the opertaion and had transvaginal hysterectomy laterly. The overall anatomical correction rate was 94% (68/72). Six patients (8%, 6/72) had mesh exposures at 3-9 months after the opertaion. Scores of PFDI-20 decreased sifnificantly after the procedure (118.2±25.2 vs 12.1±8.0 vs 12.5±9.5 vs 13.0±9.9, P< 0.05). The patients' satisfaction rate was 92% (66/72). CONCLUSION This modified Prolift procedure, without preceding partial trachelectomy or hysterectomy, could effectively and safely correct POP with coexistent cervical elongation.

Abstract
Lipopolysaccharide (LPS), the major component of the outer cell wall of Gram-negative bacteria, activates the immune system and threatens the health of livestock and poultry. However, little is known about the genes and pathways involved in the immune response of ducklings to LPS. To elucidate the genes involved in the response of 7-day-old duckling spleens treated with LPS, RNA from LPS-treated and control duckling spleens was analyzed by RNA-Seq. The results showed 11,095 and 10,840 genes with >10 clean reads in the LPS-treated and control groups, respectively. Among these genes, 89 were differentially expressed (log2 ratio ≥ 1, P ≤ 0.01, false discovery rate ≤ 0.001); 67 of these were upregulated and 22 were downregulated in the LPS-treated group compared to the control. GO and GO-rich analysis showed that differentially expressed genes were enriched in 13 functional categories (P < 0.05). Pathway analysis and pathway richness analysis showed that differentially expressed genes were enriched in six pathway categories (P < 0.05). Further analysis showed that some immune system-related signaling pathways, such as the hematopoietic cell lineage, Toll-like receptor signaling pathway, T cell receptor signaling pathway, T cell receptor signaling pathway, complement and coagulation cascades, antigen processing and presentation, and chemokine signaling pathway, are active during the immune response. To confirm the RNA-Seq results, we detected CCL4, LBP, CD71, and STEAP3 expression using real-time PCR analysis, and the results were consistent with the RNA-Seq results. Our results provide new information on the genes involved in the immune response of duckling spleens to LPS.

Abstract
There is limited information about microRNAs (miR-NAs) in H9N2 subtype influenza virus-infected chicken cells or tissues. In this study, 10,487,469 and 13,119,795 reads were obtained from in-fected and non-infected chicken embryo fibroblasts, respectively. Seven hundred and thirty-six and 1004 miRNAs, including mature miRNAs and precursors, were obtained from the infected and non-infected fibro-blasts, respectively. Of those miRNAs, 48 were expressed differently between the groups: 37 had a low expression level in the infected chick-en embryo fibroblast, and the remaining 11 had a higher expression level. Every miRNA was predicted to target immune response-related genes. It has been found that some of the miRNAs, such as gga-miR-146c, gga-miR-181a, gga-miR-181b, gga-miR-30b, gga-miR-30c, gga-miR-30e, and gga-miR-455, are expressed differently in other types of influenza-infected chicken cells or tissues.

Abstract
Significant liver disease has been reported in chronic hepatitis B patients with normal alanine aminotransferase (ALT). Liver biopsy (LB) is the current gold standard for assessing hepatic inflammation and fibrosis in patients with chronic HBV. However, associated risks have led to the development of noninvasive models. Their utility in patients with normal ALT is unknown. FIB-4 and aspartate aminotransferase (AST)-to-platelet ratio index (APRI) were calculated for patients with chronic HBV infection undergoing biopsy. The performance of each model and AUROC for predicting significant fibrosis (Scheuer's score ≥ S2) were determined for the entire cohort and stratified by elevated (≥50 U/L) and normal ALT. Two-hundred and thirty-one liver biopsies were included. The number of patient with normal ALT was 140, and 22.1% had significant fibrosis. The AUROC curve for patients with normal ALT was 0.81 for FIB-4 and 0.80 for APRI, compared with 0.71 for FIB-4 and 0.72 for APRI for those with mildly elevated ALT level. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of FIB-4 were 0.63, 0.88, 0.61 and 0.93, for patients with normal ALT; the values for APRI were 0.40, 0.88, 0.33 and 0.93. Both FIB-4 and APRI are useful for identification of those without significant fibrosis. However, because they have poor PPV, LB will continue to be used for assessment of HBV-infected patients with normal ALT and mildly elevated ALT.

Abstract
Two experiments were conducted to investigate the effects of supplemental glutamine on growth performance, plasma parameters and LPS-induced immune response of weaned barrows after castration. In experiment 1, forty-eight weaned male piglets were used and fed maize and soybean meal diets supplemented with 0 (Control) or 2% L-Gln (Gln+) for 25 days. The results indicated that the Gln+ group tended to increase average daily gain compared to control in stages of days 7 to 14 and 0 to 25. The Gln+ had significantly better feed efficiency than the control group did during days 14 to 25 and 0 to 25. The plasma blood urea nitrogen and alkaline phosphatase contents of Gln+ group were higher than those of the control group on day 14 post-weaning. In experiment 2, sixteen weaned male piglets were injected with E. coli K88+ lipopolysaccharide (LPS) on day 14 post-weaning. The results showed that the Gln+ group had lower concentrations of plasma adrenocorticotrophic hormone and cortisol than the control group on day 14 pre-LPS challenge. In addition, Gln+ group had higher plasma IgG concentration than the control group for pre- or post-LPS challenged on day 14 post-weaning. In summary, dietary supplementation of Gln was able to alleviate the stressful condition and inflammation associated with castration in weaned barrows, and to improve their immunity and growth performance in the early starter stage.
