Abstract
Objective: To summarize the characteristics of multisystem deformities in patients with Klippel-Feil syndrome (KFS) combined with congenital scoliosis (CS). Methods: Within the framework of the "Deciphering Disorders Involving Scoliosis and Comorbidities (DISCO)" research collaboration, a retrospective analysis was conducted on patients diagnosed with KFS and CS at Peking Union Medical College Hospital between April 2005 and August 2022. Patient data, including imaging examinations and medical records, were collected to summarize the spinal and associated deformities. Results: A total of 82 KFS patients with concurrent CS were included, comprising 42 males and 40 females. The average age was (12.8±8.9) years. Among the KFS patients, there were 31 cases of Type Ⅰ, 12 cases of Type Ⅱ, and 39 cases of Type Ⅲ. The most common location for the major curve of scoliosis was the mid-thoracic segment (42 cases, 51.2%). Hemivertebrae deformities were most frequently observed in the upper thoracic segment (31 cases, 60.8%). There were no statistically significant differences in age, gender, major curve Cobb angle, or region of hemivertebrae occurrence among the different types of KFS (all P>0.05). Apart from spinal vertebral deformities, intraspinal deformities had the highest comorbidity rate (33 cases, 40.2%). The subjects were divided into two groups based on the presence or absence of intraspinal deformity (absence as group G0, presence as group G1), there was a statistically significant difference in the main Cobb angle [M(Q1, Q3)] between the two groups, which was 45.0° (27.5°, 62.0°) and 60.0° (37.5°, 83.5°), respectively (P=0.044). Additionally, a portion of the patients had concurrent cardiovascular system abnormalities (13 cases, 15.9%), craniofacial-ocular-auricular abnormalities (8 cases, 9.8%), genitourinary system abnormalities (7 cases, 8.5%), and gastrointestinal abnormalities (2 cases, 2.4%). Conclusions: Patients with KFS combined with CS commonly present with a major curve of spinal deformity in the mid-thoracic segment and often have comorbidities involving multiple systems. When combined with intraspinal anomalies, the major curve exhibits a greater degree of curvature.

Abstract
Objective: To investigate the impact of relative locations of multiple foci and microsatellite status of sporadic, synchronous, multiple, primary, colorectal carcinomas on clinicopathological features and prognosis. Methods: The clinicopathologic and prognostic data of 278 patients with sporadic, synchronous, multiple, primary, colorectal carcinomas who had been admitted to the Department of Colorectal Surgery at Zhejiang Cancer Hospital from January 2008 to July 2022 were retrospectively collected. The patients were categorized into three groups based on the relative locations of their multiple cancer foci: (1) a right-sided group that comprised patients with multiple cancer foci in the cecum, ascending colon, hepatic flexure of the colon, and transverse colon; (2) a left-sided group that comprised patients with multiple cancer foci in the splenic flexure of the colon, descending colon, sigmoid colon, and rectum; and (3) a left- and right-sided group that comprised patients with multiple cancer foci in the right half of the colon and left half of the colon/rectum. Additionally, the patients were further divided into two groups based on microsatellite status: a high microsatellite instability (MSI-H) and a low MSI/stable MSI (MSI/L&MSS) group. We compared differences in clinical characteristics and prognostic indicators between these groups. The χ2 test was utilized to compare selected clinical characteristics, whereas Kaplan-Meier survival analyses and log-rank tests were performed to compare their effects on prognosis. Result: Among 278 patients with SSCRC, 256 (92.1%) presented with two cancer foci and 22 (7.9%) with more than two foci. Additionally, 255 patients (91.7%) had adenocarcinomas, whereas the remaining 23 (8.3%) had mucinous adenocarcinomas. Lymph node metastases were identified in 136 patients (48.9%); the cancer foci had infiltrated beyond the muscular layer in 238 (85.6%); and 147 patients (52.9%) were diagnosed with TNM Stage III-IV disease. There were 155 patients (55.8%) in the left-sided group, 55 (19.8%) in the right-sided group, and 68 (24.5%) in the left- and right-sided group. Immunohistochemical examination of all four mismatch repair proteins were performed in 199 cases, revealing that 166 of these patients had MSI/L&MSS and 33 MSI-H disease. In the left-sided, left- and right-sided, and right-sided groups, the proportion of women was 16.8% (26/155), 26.5% (18/68), and 49.1% (27/55), respectively; these differences are statistically significant (χ2=22.335, P<0.001). The proportions of patients with more than three cancer foci were 5.2% (8/155), 16.2% (11/68), and 5.5% (3/55), respectively; these differences are statistically significant (χ2=8.438, P=0.015). The proportions of mucinous adenocarcinomas were 4.5% (7/155), 8.8% (6/68), and 18.2% (10/55), respectively; these differences are statistically significant (χ2=10.026, P=0.007). The proportions of patients with lymph node metastases were 55.5% (86/155), 48.5% (33/68), and 30.9% (17/55); these differences are statistically significant (χ2=9.817, P=0.007). The proportions of patients with Stage T3 & T4 disease in each group according to location were 81.3% (126/155), 88.2% (60/68), and 94.5% (52/55), respectively; these differences are statistically significant (χ2=6.293,P=0.043). The proportions of TNM Stage III-IV tumors were 59.4% (92/155), 54.4% (37/68), and 32.7% (18/55), respectively; these differences are statistically significant (χ2=11.637, P=0.003). Age, size of cancer foci, presence of distant metastasis, adenoma, nerve invasion, and vascular invasion did not differ significantly between the three groups (all P>0.05). Compared with those with MSI-H, patients with MSI/L&MSS disease were more likely to be aged >65 years and male (50.6% [84/166] vs. 15.2% [5/33], χ2=13.994,P<0.001; 80.7% [134/166] vs. 54.5% [18/33], χ2=10.457,P=0.001), more likely to be in the left-sided group (63.3% [105/166] vs. 24.2% [8/33], χ2=18.232, P<0.001), had a higher proportion of cancer foci of diameter <4 cm (54.8% [91/166] vs. 33.3% [11/33], χ2=5.086,P=0.024), and a lower proportion of mucinous adenocarcinomas (4.2% [7/166] vs. 27.3% [9/33], χ2=19.791,P<0.001), more likely to develop distant metastases (22.3% [37/166] vs. 6.1% [2/33], χ2=4.601,P=0.032), more likely to have lymph node metastases (57.2% [95/166) vs. 24.2% [8/33], χ2=11.996,P<0.001) and nerve invasion (28.9% [48/166] vs. 6.1% [2/33], χ2=7.643, P=0.006), had a higher proportion of TNM Stage III-IV disease (60.2% [100/166] vs. 24.2% [8/33], χ2=14.374, P<0.001), and a smaller proportion of family history of tumors (28.9% [48/166] vs. 60.6% [20/33], χ2=12.228, P<0.001). All the above-listed differences are statistically significant (all P<0.05). The differences in number of cancer foci, depth of infiltration, presence or absence of adenomas, and vascular invasion were not statistically significant (all P>0.05). In the 33 patients with MSI-H status and mismatch repair protein loss, the highest frequency of deletion was found in PMS-2 (66.7%, 22/33), followed by MLH-1 (57.6%, 19/33), whereas the proportions of MSH-2 (33.3%, 11/33) and MSH-6 (24.2%, 8/33) deletions were relatively low. There were statistically significant differences in the 3-year overall survival rates among the groups according to relative locations of cancer foci. The 3-year overall survival rates were 96.8%, 79.6%, and 88.5% in the right-sided, left- and right-sided, and left-sided groups, respectively (P=0.021). As to microsatellite status, the 3-year overall survival rate of patients with MSI-H disease was 93.8%, which is significantly better than the 78.4% for those with MSI/L & MSS (P=0.026). Conclusions: Among sporadic, synchronous, multiple, primary, colorectal carcinomas, those with right-sided disease had the deepest local infiltration, whereas those with left-sided disease had the greatest number of lymph node metastases, most advanced clinical TNM stage, lowest percentage of MSI-H disease, and the poorest prognosis.

Abstract
Objective: To analyze the clinical and molecular diagnostic status of Fanconi anemia (FA) in China. Methods: The General situation, clinical manifestations and chromosome breakage test and genetic test results of 107 pediatric FA cases registered in the Chinese Blood and Marrow Transplantation Registry Group (CBMTRG) and the Chinese Children Blood and Marrow Transplantation Registry Group (CCBMTRG) from August 2009 to January 2022 were analyzed retrospectively. Children with FANCA gene variants were divided into mild and severe groups based on the type of variant, and Wilcoxon-test was used to compare the phenotypic differences between groups. Results: Of the 176 registered FA patients, 69 (39.2%) cases were excluded due to lack of definitive genetic diagnosis results, and the remaining 107 children from 15 hospitals were included in the study, including 70 males and 37 females. The age at transplantation treatment were 6 (4, 9) years. The enrolled children were involved in 10 pathogenic genes, including 89 cases of FANCA gene, 7 cases of FANCG gene, 3 cases of FANCB gene, 2 cases of FANCE gene and 1 case each of FANCC, FANCD1, FANCD2, FANCF, FANCJ, and FANCN gene. Compound heterozygous or homozygous of loss-of-function variants account for 69.2% (72/104). Loss-of-function variants account for 79.2% (141/178) in FANCA gene variants, and 20.8% (37/178) were large exon deletions. Fifty-five children (51.4%) had chromosome breakage test records, with a positive rate of 81.8% (45/55). There were 172 congenital malformations in 80 children.Café-au-Lait spots (16.3%, 28/172), thumb deformities (16.3%,28/172), polydactyly (13.9%, 24/172), and short stature (12.2%, 21/172) were the most common congenital malformations in Chinese children with FA. No significant difference was found in the number of congenital malformations between children with severe (50 cases) and mild FANCA variants (26 cases) (Z=-1.33, P=0.185). Conclusions: FANCA gene is the main pathogenic gene in children with FA, where the detection of its exon deletion should be strengthened clinically. There were no phenotypic differences among children with different types of FANCA variants. Chromosome break test is helpful to determine the pathogenicity of variants, but its accuracy needs to be improved.

Abstract
Objective: To compare early outcomes between transurethral thulium laser vapoenucleation of prostate and transurethral thulium laser enucleation of prostate for the treatment of benign prostatic hyperplasia (BPH). Methods: Retrospective analysis was conducted on the clinical data of 1 638 BPH patients admitted to the Department of Urology of Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021. There were 916 patients underwent transurethral thulium laser vapoenucleation of prostate (ThuVEP group) and 722 patients underwent transurethral thulium laser enucleation of prostate (ThuLEP group). The operation time, eliminated tissue weight, surgical complications, duration of post-operative catheter implantation were compared between the two groups. The improvement of International Prostate Symptom Score (IPSS), Quality of Life Index (QoL), maximum uroflow rate (Qmax) and post-void residual urine volume (PVR) at 1 month after operation was compared between the two groups. Results: There were no significant differences in age, preoperative and 1-month postoperative prostate volume, IPSS score, QoL score, Qmax, and PVR between the ThuVEP and ThuLEP group (all P>0.05). There were no significant differences in perioperative indicators such as operation time, cutting or enucleation time, tissue crushing time, tissue weight, hemoglobin change, catheter indwelling time, and postoperative hospital stay between ThuVEP group and ThuLEP group (all P>0.05). The incidence of minor gross hematuria after extubation in the ThuVEP group was 7.8% (56/916), which was lower than 9.4% (65/722) in the ThuLEP group (P=0.026); the incidence of temporary incontinence at 1 month after surgery was 5.2% (38/916) in ThuVEP group, lower than 11.9% (86/722) in ThuLEP group (P<0.001). A total of 3 patients (0.4%) in ThuLEP group required operative intervention for severe post-operation bleeding, but none of ThuVEP group suffered from this kind of surgical complications. Conclusions: ThuVEP has similar efficacy with ThuLEP for the treatment of BPH. ThuVEP can significantly reduce the incidence of post-operation temporary urine incontinence, and has much superiority in stanching bleeding.

Abstract
Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34+0 weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

Abstract
Objective: To evaluate the prevalence and relevant factors of primary angle-closure glaucoma (PACG) in the middle-aged and elderly (40 years old and above) Chinese population. Methods: Epidemiological literature (of English and/or Chinese language) on prevalence of PACG in China between 2000 and 2022 were retrieved from PubMed, Embase, Web of Science, CNKI, and Wanfang database. Two researchers conducted the process of document retrieval, inclusion, quality assessment and data extraction independently based on inclusion and exclusion criteria. Disagreement was resolved by consensus with a third researcher. The heterogeneity among studies was assessed by using the I2 statistics, and a corresponding model was used for the meta-analysis. Subgroup analysis (gender, age, survey date, place of residence, diagnostic criteria, and temperature zone), as well as sensitivity analysis and publication bias analysis, were conducted. Results: Twenty-three studies were included in this research. Among them, eight were of high-quality and fifteen were of middle-quality. In the past 20 years, the PACG prevalence in middle-aged and elderly (40 years and older) Chinese population was 1.35% (95%CI:1.08% to 1.61%). Chinese women (1.40%) were more likely to have PACG than men (0.96%, P<0.01). The PACG prevalence had a positive correlation with age (P<0.01). The prevalence was similar between urban (1.3%) and rural (1.2%, P=0.61) areas. The PACG prevalence from studies in which the diagnostic criteria of PACG requested the symptom of vision or optic nerve damage (1.1%) was lower than that those without such requirement (1.7%, P<0.01). In mid-temperate zone, the prevalence was higher (1.7%, P=0.02). Conclusions: The PACG prevalence in middle-aged and elderly (40 years old and above) Chinese population was 1.35% in the last 20 years. The prevalence of PACG varies across age, regions, and other variations. This risk is higher in the elderly, women, and people in cold regions among Chinese population.

Abstract
Background Preoperative prediction of microvascular invasion (MVI) is critical for treatment strategy making in patients with hepatocellular carcinoma (HCC). We aimed to develop a deep learning (DL) model based on preoperative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to predict the MVI status and clinical outcomes in patients with HCC. Methods We retrospectively included a total of 321 HCC patients with pathologically confirmed MVI status. Preoperative DCE-MRI of these patients were collected, annotated, and further analyzed by DL in this study. A predictive model for MVI integrating DL-predicted MVI status (DL-MVI) and clinical parameters was constructed with multivariate logistic regression. Results Of 321 HCC patients, 136 patients were pathologically MVI absent and 185 patients were MVI present. Recurrence-free survival (RFS) and overall survival (OS) were significantly different between the DL-predicted MVI-absent and MVI-present. Among all clinical variables, only DL-predicted MVI status and a-fetoprotein (AFP) were independently associated with MVI: DL-MVI (odds ratio [OR] = 35.738; 95% confidence interval [CI] 14.027–91.056; p < 0.001), AFP (OR = 4.634, 95% CI 2.576–8.336; p < 0.001). To predict the presence of MVI, DL-MVI combined with AFP achieved an area under the curve (AUC) of 0.824. Conclusions Our predictive model combining DL-MVI and AFP achieved good performance for predicting MVI and clinical outcomes in patients with HCC.

Abstract
OBJECTIVE To systematically evaluate the efficacy of Shengmai San in patients with cardiotoxicity of anthracyclines. METHODS Randomized controlled trials (RCTs) were identified by searching China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database (CBM), PubMed, Cochrane Library, and Embase Databases from the inceptions until December 2020. The Cochrane Handbook was used to evaluate the risk of bias in the included studies. Data analysis was conducted using RevMan 5.3 software. RESULTS Totally 19 RCTs with 2,331 participants were included in this review. Results showed that in improving arrhythmia (13 RCTs, n=1,877, RR=0.37, 95%CI 0.25 to 0.52, P<0.00001), the treatment group was superior to the control group. In terms of reducing left ventricular end-diastolic diameter (LVEDD, 2 RCTs, n=128, MD=-0.79, 95%CI -0.93 to -0.65, P<0.00001) and left ventricular end systolic diameter (LVESD, 2 RCTs, n=128, MD=-0.58, 95%CI -0.82 to -0.35, P<0.00001), the treatment group was also better than the control group. In reducing myocardial enzymes such as creatine kinase (CK) [(3 RCTs, n=256, SMD=-0.80, 95%CI -1.16 to -0.44, P<0.0001), (2 RCTs, n=126, SMD=-0.62, 95%CI -0.98 to -0.26, P=0.0007)], the treatment group was superior to the control group. CONCLUSION Shengmai San has a positive effect on the treatment of cardiotoxicity from anthracyclines. However, in the future, it is still necessary to conduct high-quality RCTs to verify its efficacy.

Abstract
Background We demonstrated that drinking hydrogen-rich water (HRW) inhibits endometrial tumor growth in our previous work. This research is to identify differentially expressed proteins (DEPs) between HRW and purified water groups in a xenograft mouse model of endometrial cancer (EC). Methods Samples were analyzed using tandem mass tags (TMTs) coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS). DEPs were identified using bioinformatics to determine potential molecular functions and immunohistochemical (IHC) staining. Results In total, 11 DEPs were identified in the HRW group relative to the control. The up-regulated proteins included Gatad1, Ttyh3, Nek4, Dyrk2, and Gimap1, while the down-regulated proteins included SP1, Msl1, Plekha7, Dtwd2, MSRA, and KRAS. Gene Ontology (GO) annotations and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were associated with the binding region, biological regulation, endocrine resistance, estrogen signaling, choline metabolism in cancer and human cytomegalovirus infection. Furthermore, network analysis indicated that KRAS and MSRA interact with YWHAE. KRAS, YWHAE and SP1 were strongly expressed, while MSRA was weak expressed in atypical hyperplasia and EC tissue as well as in HRW group in xenograft tumor tissue. Conclusions KRAS, YWHAE, SP1 and MSRA might be regarded as focused biomarkers to assess the prognosis of EC.

Abstract
Objective: To examine the short and long-term clinical outcomes of total arterial coronary artery bypass grafting. Methods: Clinic data of 208 patients with left main and multiple vessel coronary artery disease and undertaken total arterial coronary artery bypass grafting from February 2009 to December 2019 in Department of Cardiac Surgery, Rui Jin Hospital, Shanghai Jiao Tong University School of Medicine were analyzed retrospectively. There were 188 males and 20 females with an age of (54.7±10.7) years (range: 32 to 79 years). The harvest of arterial conduits and grafting strategies were depended upon the individual patient characteristics and surgeon's experience. Left internal thoracic artery (LITA) was applied in 207 cases, right internal thoracic artery (RITA) in 38 cases (bilateral internal thoracic artery (BITA) in 37 cases), and radial artery (RA) in 187 cases (188 grafts). The graft number per case was 2.6±0.7 (range: 2 to 4). Surgical procedures was completed with off-pump technique in 98.1% patients (204/208). Subgroup analysis was carried out between subgroup BITA (n=37) and subgroup SITA (single ITA+RA) (n=171). The t test, χ(2) test or Fisher exact test were used to compare the clinic characteristics between the two subgroups. The Kaplan-Meier curve was used to estimate the rate of late mortality, major adverse cardiac cerebrovascular event (MACCE), and target vessel revascularization (TVR). A Cox proportional hazards model was used to identify the independent prognosis factors of late mortality. Results: The overall mortality within 30 days postoperatively was 1.4%(3/208). The incidences of perioperative MACCE, re-operation for bleeding and deep sternal wound infection (DSWI) were 1.9%(4/208), 0.5%(1/208) and 1.4%(3/208), respectively. Perioperative myocardial infarction and TVR were not observed. There was no significant difference of 30-day mortality, MACCE, bleeding and DSWI between subgroup BITA and SITA+RA (all P>0.05). In a follow-up period of (5.4±2.8)years (range: 0.2 to 10.9 years), the incidence of all-cause mortality at 1-, 5- and 10-year was 2.3%, 3.4% and 6.9%, respectively. The incidence of MACCE was 3.9%,11.2% and 28.5%, respectively. The rate of TVR was 0.4%, 3.7% and 11.9%, respectively. Age>65 was an independent prognosis factor of late mortality (HR=1.125, 95% CI:1.050 to 1.205, P<0.01). Conclusions: Total arterial coronary bypass grafting is safe and achievable with proper patient selection and surgical strategies. It significantly decreases the risks of late mortality and repeated revascularization.

Abstract
The selection of conduit has always been one of the most perennially debated topic in the field of coronary artery bypass grafting (CABG) . Arterial grafts have demonstrated excellent biological characteristics and long-term patency in CABG. Clinical observations and randomized clinical trials over the past two decades have shown that the internal thoracic artery is the gold standard graft. Multi-arterial and total-arterial CABG significantly improves patients' long-term survival, but there are technical challenges and concerns of sternal complication. Currently multi-arterial and total-arterial CABG are strongly advocated and increasingly applied worldwide. Several guidelines have been published and updated, as well as Chinese expert consensus. Coronary surgery in China is paving anupper stage of quality improvement. Arterial coronary artery bypass grafting should be carried out more broadly in China as evidence accumulation and excellent long-term clinical results.

Abstract
Abstract
Introduction
The association of diabetes and vein graft patency after coronary artery bypass grafting (CABG) remains controversial. In patients with diabetes, impaired endothelial function in vein grafts and high platelet turnover might result in early vein graft failure. The DACAB trial showed ticagrelor plus aspirin significantly increased 1-year vein graft patency vs. aspirin alone, while no significant difference between ticagrelor alone and aspirin alone. However, whether the results is different between the patients with or without diabetes is unknown.
Purpose
To assess the effects of ticagrelor with or without aspirin vs. aspirin alone on 1-year vein grafts patency after CABG in patients with or without diabetes.
Methods
We examined the subgroups of patients with and without diabetes from DACAB trial (NCT02201771), in which 500 patients were randomized to 1 of 3 antiplatelet regimens (ticagrelor 90mg twice daily plus aspirin 100mg once daily, T+A group; ticagrelor 90mg twice daily, T group; or aspirin 100mg once daily, A group) within 24 hours post-CABG. The primary outcome was 1-year vein graft patency (FitzGibbon grade A) assessed by multi-slice computed tomographic angiography or coronary angiography.
Results
According to the baseline medical history and/or glycated hemoglobin (HbA1c) ≥6.5%, 283 patients with 818 vein grafts were allocated to the non-diabetes subgroup, remaining 217 patients with 642 vein grafts to the diabetes subgroup. By per-graft analysis, no significant difference on 1-year vein graft patency rate was observed between non-diabetes and diabetes subgroup (84.6% [692/881] for non-diabetes vs. 80.2% [515/642] for diabetes, adjusted odds ratio (OR) =1.39, 95% CI: 0.92–2.09, P=0.116). In T+A group, 1-year vein graft patency rates were 91.0% (244/268) for non-diabetes vs. 85.8% (188/219) for diabetes; In T group, 85.0% (221/260) for non-diabetes vs. 80.3% (183/228) for diabetes; In A group, 78.3% (227/290) for non-diabetes vs. 73.9% (144/195) for diabetes. Ticagrelor plus aspirin showed higher vein graft patency rate than aspirin alone in both non-diabetes and diabetes subgroup (non-diabetes: adjusted OR = 0.34, 95% CI: 0.17–0.69, and diabetes: adjusted OR = 0.42, 95% CI: 0.19–0.91, P for interaction = 0.524), whereas ticagrelor alone did not show improvement on vein graft patency compared with aspirin alone in both subgroups (non-diabetes: adjusted OR=0.62, 95% CI: 0.32–1.20, and diabetes: adjusted OR = 0.65, 95% CI: 0.33–1.31, P for interaction = 0.795). Similar results were showed by per-patient analysis. A total 16 major adverse cardiovascular events occurred, 8 (2.8%) for non-diabetes and 8 (3.7%) for diabetes.
Conclusion
In the DACAB trial, diabetes was not found to be associated with decreased vein graft patency at 1 year after CABG. The effect of ticagrelor plus aspirin on improvement of 1-year vein graft patency, when compared with aspirin alone, is consistent in patients with or without diabetes.

Abstract
To investigate the current status of postgraduates training in public health and preventive medicine in China. In this study, a questionnaire survey was conducted among directors of enrollment and teaching in 22 universities with postgraduate admission qualifications in corresponding disciplines nationwide. In 2016, full-time postgraduates were mainly academic masters. In addition to the graduate entrance examination, the common enrollment mode in colleges was to enroll a high qualified student with recommendations from relevant experts or institutions and an exemption from entrance examination (20/22). The emphasis on training contents between academic and public health master was different. Currently, the scale of public health postgraduate enrollment in public health and preventive medicine in China is stable, and the training program is reasonable, but there is an issue of monotonous model and uneven distribution of enrollment.

Abstract
In order to understand the status of the cultivation of the masters of public health (MPH) in colleges in China and improve the cultivation model, an electronic questionnaire survey were conducted among 22 schools of public health in colleges. The result showed that the size and the enrolment scale of Chinese MPH students were relatively small, and the training objectives were still unclear. There was no obvious difference between the curriculum setting for MPH and academic master degree. The practical skill-oriented courses and emergency response ability of public health practice were insufficient. The cultivation model of MPH should be improved in future.

Abstract
In order to study the significance of CD(276) and CD(133) in the development and progression of colorectal cancer (CRC), the expression of CD(276) and CD(133) was detected by immunohistochemistry in CRC and precancerous lesions. The results showed that the intensity of CD(276) and CD(133) in CRC samples was higher than that in adenoma group and non-adenoma group. CD(276) and CD(133) single and double positive expression were significantly correlated with CRC lymph node metastasis, distant metastasis and survival. CD(276) and CD(133) are significantly correlated to the development and progression of CRC and associated with poor prognosis.

Abstract
PURPOSE To compare the detection rate of HBV antigens in different samples, and to explore the significance of saliva transmission in the spread of HBV. METHODS Eight hundred and ninety-one ordinary saliva samples, 578 bloody saliva samples and 450 serum samples of dental patients were collected from Shanghai Sixth People's Hospital and Dahua Hospital, and HBsAg, HBsAb, HBeAg, HBeAb and HBcAb were detected by ELISA method. SPSS19.0 software package was used for chi-square test. RESULTS There was no significant difference in gender, age and household registration between three types of saliva sample: ordinary saliva, bloody saliva and serum (P>0.05). Eight, 11 and 12 of HBV-M combination modes were detected from the above three samples. Six "HHAs" were detected from the normal saliva samples (0.67%), and the detection rate was similar to bloody saliva samples (0.87%) and serum samples (1.56%) (P>0.05). HBsAg detection rate in serum samples was significantly higher than bloody saliva and ordinary saliva (P<0.001). The difference between ordinary saliva and bloody saliva and between different age-group, sex-group, and census register group in serum samples was of no significant difference (P>0.05), and so was HBeAg. CONCLUSIONS Saliva is an important transmission route of hepatitis B, and should be taken seriously. When the infectivity is strong, the virus content in saliva is high. Hepatitis B virus in saliva may come from other than sources except blood.

Abstract
Objective: To evaluate the significance of bacteria detection with filter paper method on diagnosis of diabetic foot wound infection. Methods: Eighteen patients with diabetic foot ulcer conforming to the study criteria were hospitalized in Liyuan Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from July 2014 to July 2015. Diabetic foot ulcer wounds were classified according to the University of Texas diabetic foot classification (hereinafter referred to as Texas grade) system, and general condition of patients with wounds in different Texas grade was compared. Exudate and tissue of wounds were obtained, and filter paper method and biopsy method were adopted to detect the bacteria of wounds of patients respectively. Filter paper method was regarded as the evaluation method, and biopsy method was regarded as the control method. The relevance, difference, and consistency of the detection results of two methods were tested. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of filter paper method in bacteria detection were calculated. Receiver operating characteristic (ROC) curve was drawn based on the specificity and sensitivity of filter paper method in bacteria detection of 18 patients to predict the detection effect of the method. Data were processed with one-way analysis of variance and Fisher's exact test. In patients tested positive for bacteria by biopsy method, the correlation between bacteria number detected by biopsy method and that by filter paper method was analyzed with Pearson correlation analysis. Results: (1) There were no statistically significant differences among patients with wounds in Texas grade 1, 2, and 3 in age, duration of diabetes, duration of wound, wound area, ankle brachial index, glycosylated hemoglobin, fasting blood sugar, blood platelet count, erythrocyte sedimentation rate, C-reactive protein, aspartate aminotransferase, serum creatinine, and urea nitrogen (with F values from 0.029 to 2.916, P values above 0.05), while there were statistically significant differences among patients with wounds in Texas grade 1, 2, and 3 in white blood cell count and alanine aminotransferase (with F values 4.688 and 6.833 respectively, P<0.05 or P<0.01). (2) According to the results of biopsy method, 6 patients were tested negative for bacteria, and 12 patients were tested positive for bacteria, among which 10 patients were with bacterial number above 1×10(5)/g, and 2 patients with bacterial number below 1×10(5)/g. According to the results of filter paper method, 8 patients were tested negative for bacteria, and 10 patients were tested positive for bacteria, among which 7 patients were with bacterial number above 1×10(5)/g, and 3 patients with bacterial number below 1×10(5)/g. There were 7 patients tested positive for bacteria both by biopsy method and filter paper method, 8 patients tested negative for bacteria both by biopsy method and filter paper method, and 3 patients tested positive for bacteria by biopsy method but negative by filter paper method. Patients tested negative for bacteria by biopsy method did not tested positive for bacteria by filter paper method. There was directional association between the detection results of two methods (P=0.004), i. e. if result of biopsy method was positive, result of filter paper method could also be positive. There was no obvious difference in the detection results of two methods (P=0.250). The consistency between the detection results of two methods was ordinary (Kappa=0.68, P=0.002). (3) The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of filter paper method in bacteria detection were 70%, 100%, 1.00, 0.73, and 83.3%, respectively. Total area under ROC curve of bacteria detection by filter paper method in 18 patients was 0.919 (with 95% confidence interval 0-1.000, P=0.030). (4) There were 13 strains of bacteria detected by biopsy method, with 5 strains of Acinetobacter baumannii, 5 strains of Staphylococcus aureus, 1 strain of Pseudomonas aeruginosa, 1 strain of Streptococcus bovis, and 1 strain of bird Enterococcus. There were 11 strains of bacteria detected by filter paper method, with 5 strains of Acinetobacter baumannii, 3 strains of Staphylococcus aureus, 1 strain of Pseudomonas aeruginosa, 1 strain of Streptococcus bovis, and 1 strain of bird Enterococcus. Except for Staphylococcus aureus, the sensitivity and specificity of filter paper method in the detection of the other 4 bacteria were all 100%. The consistency between filter paper method and biopsy method in detecting Acinetobacter baumannii was good (Kappa=1.00, P<0.01), while that in detecting Staphylococcus aureus was ordinary (Kappa=0.68, P<0.05). (5) There was no obvious correlation between the bacteria number of wounds detected by filter paper method and that by biopsy method (r=0.257, P=0.419). There was obvious correlation between the bacteria numbers detected by two methods in wounds with Texas grade 1 and 2 (with r values as 0.999, P values as 0.001). There was no obvious correlation between the bacteria numbers detected by two methods in wounds with Texas grade 3 (r=-0.053, P=0.947). Conclusions: The detection result of filter paper method is in accordance with that of biopsy method in the determination of bacterial infection, and it is of great importance in the diagnosis of local infection of diabetic foot wound.

Abstract
Background: Congenital cataract (CC) is the leading cause of visual impairment or blindness in children worldwide. Because of highly genetic and clinical heterogeneity, a molecular diagnosis of the lens disease remains a challenge. Methods: In this study, we tested a three-generation Chinese family with autosomal dominant CCs by targeted sequencing of 45 CC genes on next generation sequencing and evaluated the pathogenicity of the detected mutation by protein structure, pedigree validation, and molecular dynamics (MD) simulation. Results: A novel 15 bp deletion on GJA8 (c.426_440delGCTGGAGGGGACCCT or p. 143_147delLEGTL) was detected in the family. The deletion, concerned with an in-frame deletion of 5 amino acid residues in a highly evolutionarily conserved region within the cytoplasmic loop domain of the gap junction channel protein connexin 50 (Cx50), was in full cosegregation with the cataract phenotypes in the family but not found in 1100 control exomes. MD simulation revealed that the introduction of the deletion destabilized the Cx50 gap junction channel, indicating the deletion as a dominant-negative mutation. Conclusions: The above results support the pathogenic role of the 15 bp deletion on GJA8 in the Chinese family and demonstrate targeted genes sequencing as a resolution to molecular diagnosis of CCs.

Abstract
BACKGROUND To compare the effectiveness of tenocutaneous suture and conventional Kessler suture techniques in treating acute closed Achilles tendon rupture. METHODS A total of 33 patients with acute closed Achilles tendon rupture who were admitted to our hospital from February 1998 to December 2008 underwent repair with either a tenocutaneous suture or Kessler suture technique. All patients were followed up for 1-5 years (mean, 3 years). RESULTS According to the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale, the excellence rate was 91% in the Kessler suture group and 98% in the tenocutaneous suture group, with a significant difference between groups. CONCLUSION Our tenocutaneous suture technique is an effective method for treating Achilles tendon rupture. It has certain advantages compared with the conventional incision method and is worthy of wide clinical application.

Abstract
Background Generation of large mate-pair libraries is necessary for de novo genome assembly but the procedure is complex and time-consuming. Furthermore, in some complex genomes, it is hard to increase the N50 length even with large mate-pair libraries, which leads to low transcript coverage. Thus, it is necessary to develop other simple scaffolding approaches, to at least solve the elongation of transcribed fragments. Results We describe L_RNA_scaffolder, a novel genome scaffolding method that uses long transcriptome reads to order, orient and combine genomic fragments into larger sequences. To demonstrate the accuracy of the method, the zebrafish genome was scaffolded. With expanded human transcriptome data, the N50 of human genome was doubled and L_RNA_scaffolder out-performed most scaffolding results by existing scaffolders which employ mate-pair libraries. In these two examples, the transcript coverage was almost complete, especially for long transcripts. We applied L_RNA_scaffolder to the highly polymorphic pearl oyster draft genome and the gene model length significantly increased. Conclusions The simplicity and high-throughput of RNA-seq data makes this approach suitable for genome scaffolding. L_RNA_scaffolder is available at http://www.fishbrowser.org/software/L_RNA_scaffolder.

Abstract
Glucocorticoids (GCs) resistance is frequently encountered in children with acute lymphoblastic leukemia (ALL), especially in T-ALL, which usually results in failure of treatment. To find new agent to overcome GC resistance of ALL is an urgent problem. Here we investigated potential effect of anisomycin on GC-resistant T-ALL CEM-C1 cells and explored involved molecular mechanisms. Dramatic growth inhibition and apoptosis in GC resistant CEM-C1 cells and GC-sensitive CEM-C7 cells induced by anisomycin were observed, which presented in a concentration- and time-dependent manner. Correspondingly, anisomycin induced cleaved caspase-3 and up-regulation of pro-apoptotic proteins (BimEL and Bad), meanwhile down-regulation of anti-apoptotic proteins (Mcl-1 and Bcl-2), both in a dose- and time-dependent manner in GC resistant CEM-C1 cells. Anisomycin also induced cell cycle arrest at G0/G1 phase in CEM-C1 cells through increasing expressions of p21 and p27, and attenuating the expression of cyclinA. The rapid up-regulation of phosphorylated mitogen-activated protein kinases (MAPKs) p38 and Jun N-terminal kinase (JNK) were observed after CEM-C1 cells were incubated with anisomycin. The activation of p38 and JNK could be blocked by respective inhibitors (SB203580 for p38 and SP600125 for JNK) accompanied with the inhibition of apoptosis and changes of apoptosis associated proteins in CEM-C1 cells. These results suggested that anisomycin induced apoptosis of CEM-C1 cells via activation of p38 and JNK, and might be an attractive new agent for treatment of GC-resistant ALL.

Abstract
AIMS Central pancreatectomy (CP) protects more normal pancreatic parenchyma than distal pancreatectomy (DP), but the safety, feasibility and long-term benefit of CP are inconclusive. This meta-analysis aims to ascertain the relative merits of CP. METHODS A systematic literature research was performed to identify comparative studies on CP and DP. Perioperative and long-term outcomes constituted the end points. Pooled risk ratios (RR) and weighted mean differences (WMD) with 95% confidence intervals (95% CI) were calculated using either fixed effects or random effects model. RESULTS Nine studies with 735 patients were included in this meta-analysis. Although CP cost more operative time than DP, the two groups had no significant differences in the volume of intraoperative blood loss, rate of intraoperative blood transfusion and length of postoperative hospital stay. According to the postoperative outcomes, although the CP group had higher overall complication rate (Fixed effects model; RR: 1.30; 95% CI: 1.05-1.62; P < 0.05) as well as overall pancreatic fistula rate (Fixed effects model; RR: 1.58; 95% CI: 1.20-2.08; P < 0.05), the two groups did not differ significantly in the fateful surgical complications such as clinically significant pancreatic fistula (Grades B and C), postoperative bleeding, reoperation and intra-abdominal effusion/abscess. Furthermore, the perioperative mortality rate was comparable between the two groups. During the follow-up period, the patients after DP were more likely to suffer pancreatic exocrine insufficiency (Fixed effects model; RR: 0.53; 95% CI: 0.32-0.86; P < 0.05) and endocrine impairment (Fixed effects model; RR: 0.19; 95% CI: 0.11-0.33; P < 0.05). CONCLUSION CP was still an acceptable and feasible procedure, especially when considering the postoperative pancreatic function preservation ability by CP.

Abstract
Achilles tendon rupture is a common injury, and its complications can impair function. Numerous operations have been described for reconstructing the ruptured tendon, but these methods can compromise the microcirculation in the tendon and can seriously damage healing of the tendon. Suturing with a minimally invasive tenocutaneous technique soon after the rupture and systematic functional exercise can greatly reduce the possibility of complications. From June 1996 to February 2007, we treated 20 patients (14 males), who ranged in age from 21 to 66 years old, with this method. After follow-up period of 1 to 7 years, the mean American Orthopedic Foot and Ankle Society Ankle Hindfoot score was 95 (range 90 to 98), and the maximum length of postoperative scarring was 3 cm. One patient again ruptured his Achilles tendon 1 year after surgery in an accident; however, after 10 months, the repaired tendon was still intact. In another patient, the nervus suralis was damaged during surgery by piercing the tension suture at the near end, causing postoperative numbness and swelling. The tension suture was quickly removed, and the patient recovered well with conservative treatment. No large irregular scars, such as those sustained during immobilization, were present over the Achilles tendon. Minimally invasive percutaneous suturing can restore the original length and continuity of the Achilles tendon, is minimally invasive, and results in fewer postoperative complications than other methods.

Abstract
BACKGROUND MicroRNAs (miRNAs) exist pervasively across viruses, plants and animals and play important roles in the post-transcriptional regulation of genes. In the common carp, miRNA targets have not been investigated. In model species, single-nucleotide polymorphisms (SNPs) have been reported to impair or enhance miRNA regulation as well as to alter miRNA biogenesis. SNPs are often associated with diseases or traits. To date, no studies into the effects of SNPs on miRNA biogenesis and regulation in the common carp have been reported. RESULTS Using homology-based prediction combined with small RNA sequencing, we have identified 113 common carp mature miRNAs, including 92 conserved miRNAs and 21 common carp specific miRNAs. The conserved miRNAs had significantly higher expression levels than the specific miRNAs. The miRNAs were clustered into three phylogenetic groups. Totally 394 potential miRNA binding sites in 206 target mRNAs were predicted for 83 miRNAs. We identified 13 SNPs in the miRNA precursors. Among them, nine SNPs had the potential to either increase or decrease the energy of the predicted secondary structures of the precursors. Further, two SNPs in the 3' untranslated regions of target genes were predicted to either disturb or create miRNA-target interactions. CONCLUSIONS The common carp miRNAs and their target genes reported here will help further our understanding of the role of miRNAs in gene regulation. The analysis of the miRNA-related SNPs and their effects provided insights into the effects of SNPs on miRNA biogenesis and function. The resource data generated in this study will help advance the study of miRNA function and phenotype-associated miRNA identification.

Abstract
BACKGROUND AND OBJECTIVE Obesity is associated with increased risk of colorectal cancer. Many studies showed that body mass index (BMI) is related to the incidence of colon cancer. This study was to explore the relationship between BMI and colon cancer in Chinese population and provide evidences for the prevention of colon cancer. METHODS Clinical data, including BMI, of 707 colon cancer patients and 709 healthy subjects were compared. RESULTS The mean BMI was significantly higher in colon cancer patients than in healthy subjects [(24.52+/-4.56) kg/m2 vs. (23.75+/-3.14) kg/m2, t=-3.72, P<0.001]. When stratified by sex and age, the BMI was always higher in colon cancer patients than in healthy subjects. Logistic regression analyses showed that BMI was an important risk factor of colon cancer (odds ratio=1.059, 95% confidence interval=1.029-1.090). CONCLUSION The occurrence of colon cancer in Chinese population is related to BMI.

Abstract
Situated in the central part of China, the Han River Basin is undergoing rapid social and economic development with some human interventions to be made soon which will profoundly influence the water environment of the basin. The integrated MIKE 11 model system comprising of a rainfall-runoff model (NAM), a non-point load evaluation model (LOAD), a hydrodynamic model (MIKE 11 HD) and a water quality model (ECOLab) was applied to investigate the impact of the Middle Route of the South-North Water Diversion Project on the Han River and the effectiveness of the 2 proposed mitigation projects, the 22 wastewater treatment plants (WWTPs) and the Yangtze-Han Water Diversion Project. The study concludes that business as usual will lead to a continuing rapid deterioration of the water quality of the Han River. Implementation of the Middle Route of the South-North Water Diversion Project in 2010 will bring disastrous consequence in the form of the remarkably elevated pollution level and high risk of algae bloom in the middle and lower reaches. The proposed WWTPs will merely lower the pollution level in the reach by around 10%, while the Yangtze-Han Water Diversion Project can significantly improve the water quality in the downstream 200-km reach. The results reveal that serious water quality problem will emerge in the middle reach between Xiangfan and Qianjiang in the future. Implementation of the South-North Water Diversion Project (phase II) in 2030 will further exacerbate the problem. In order to effectively improve the water quality of the Han River, it is suggested that nutrient removal processes should be adopted in the proposed WWTPs, and the pollution load from the non-point sources, especially the load from the upstream Henan Province, should be effectively controlled.

Abstract
In this study, a thermostable recombinant xylanase B (XynB) from Thermotoga maritima MSB8 was immobilized on nickel-chelated Eupergit C 250L. This immobilized XynB was then used to hydrolyze the autohydrolysis explosion liquor of corncob (AELC) in a packed-bed enzyme reactor for continuous production of xylooligosaccharides, especially xylobiose. When tested in batch hydrolysis of AELC, the immobilized XynB still retained its relative activity of 92.5% after 10 cycles of hydrolysis at 90 degrees C. The immobilized XynB retained 83.6% of its initial hydrolysis activity even after 168 h of hydrolysis reaction at 90 degrees C and demonstrated a half-life time of 577.6 h (24 days) for continuous hydrolysis. HPLC showed that xylobiose (49.8%) and xylose (22.6%) were the main hydrolysis products yielded during continuous hydrolysis. Xylobiose was adsorbed on an activated charcoal column and eluted with a linear gradient of 15% (v/v) ethanol to yield xylobiose with 84.7% of recovery. Also, the purity of xylobiose was up to 97.2% as determined by HPLC. Therefore, the immobilized XynB was suitable for the efficient production of xylobiose from AELC. This is the first report on the immobilization of xylanase for xylobiose production.

Abstract
OBJECTIVE To explore the regulation of hypoxia inducible factor-1alpha (HIF-1alpha) on osteoblast function in osteogenesis. METHODS Skull-cap bone of HIF-1alpha Loxp/Loxp and VHL Loxp/Loxp C57/BL6 mice were taken out and cultured so as to obtain osteoblasts which were infected with the recombinant adenovirus Ad-Cre so as to conditionally knock out the HIF-1alpha gene and its up-stream gene for von Hippel-Lindau disease (VHL) using Cre-Loxp recombinase technique. Then the osteoblasts were cultured under 2% O2 for 48 hours. Real-time PCR and Western-blotting were used to detect the mRNA and protein expression of vascular endothelial growth factor (VEGF), core binding factor al (RunX2), alkaline phosphatase (ALP) and osteocalcin (OC). Transgenic FVB mice mated with C57/BL6 mice with both HIF-1alpha and VHL alleles to obtain the mice with the osteoblasts with the HIF-1alpha and VHL genes conditionally knocked-out. At the age of 3 months the distal femurs of HIF-1alpha/VHL conditionally knocked-out mice and wild type mice were obtained to undergo hematoxylin-eosin staining and micro-CT to evaluate the bone histomorphometry and bone mineral density (BMD). RESULTS The mRNA and protein expressions of VEGF, RunX2, ALP, and OC of the HIF-1alpha conditionally knocked-out osteoblasts were all decreased and the mRNA and protein expressions of VEGF, RunX2, ALP, and OC of the VHL conditionally knocked-out osteoblasts were all increased. The values of bone histomorphometry and bone mineral density (BMD) of the HIF-1alpha conditionally knocked-out mice were both significantly lower than those of the wild-type mice, whereas the values of bone histomorphometry and BMD of the VHL conditionally knocked-out mice were both significantly higher than those of the wild-type mice (all P < 0.01). CONCLUSION Under both the physiological and pathological hypoxia environment in bone tissues HIF-1alpha can promote the bone formation ability of osteoblast.

Abstract
OBJECTIVES Chondrocytes reside in a hypoxic environment; they utilize glucose as the main energy source. Facilitated glucose transport represents the first rate-limiting step in glucose metabolism. RESULTS Here we demonstrated that hypoxia induced an elevated expression level of GLUT-1 and -3 in chondrocytes. Also elevated was hypoxia inducible factor-1alpha (HIF-1alpha) protein level. On the contrary, deletion of HIF-1alpha led to complete loss of the hypoxia-induced gene expression of GLUT-1 and 3. CONCLUSION These results suggested that chondrocytes had the capacity to detect and respond to low oxygen availability with changes in expression of oxygen-regulated genes, and that hypoxia regulation of facilitated GLUT-1 and -3 was mediated by HIF-1alpha.

Abstract
PURPOSE OF INVESTIGATION To classify endometrial cancers based on gene expression profiling, and to compare the prognostic value of the classification systems based on gene expression, grade, and stage. METHODS cDNA microarray was carried out in 32 endometrioid endometrial cancers. Differentially expressed genes were identified among tumor tissues of different grades and stages. The classification and prognosis comparison analysis was performed between histological grades, FIGO stages and gene expression profiles. RESULTS Class comparison analysis between different grade and stage endometrial cancer revealed 33 genes that are differentially expressed in tumors of different grades, ten in those of different stages, and 104 in a combined classification of grades and stages (p < 0.001). CONCLUSION The cDNA microarray technique is a feasible way to generate gene expression profiles of endometrial cancer. Classification based on gene expression patterns may be more accurate than histological grade and FIGO stage classification in predicting the prognosis of tumors.

Abstract
The aim of this work was the selection and comparison of representative infectious bursal disease virus (IBDV) strains. Nine strains of IBDV, isolated at different times and from different geographic regions of Europe and China, were characterized. Batches of all strains were prepared following standardized protocols and checked for the absence of contaminating viruses. Criteria used for their characterization were: (i) the nucleotide sequence of the VP2 variable region, (ii) binding to a panel of neutralizing monoclonal antibodies in antigen capture enzyme-linked immunosorbent assays, and (iii) virulence in specific pathogen free chickens after infection with a standardized number of median embryo infective doses. Based on the first two criteria, two of nine strains were classified as classical virulent (cv) IBDV (F52/70, Cu-1wt), and five as very virulent (vv) IBDV (849VB, 96108, HK46, GX, Harbin). Remarkably, although a clear-cut difference was demonstrable between European cvIBDV (F52/70 and Cu-1wt) and vvIBDV (849VB and 96108) strains, there was a continuum in the pathogenicity of Chinese vvIBDVs. Our results indicate the probable existence of differences in virulence within IBDV lineages determined on the basis of antigenic typing using monoclonal antibodies and the alignment of the VP2 sequences. This indicates limitations in the analysis of IBDV pathotypes based on the VP2 variable region and emphasizes that these criteria may not be sufficient for the classification of IBDV strains.

Abstract
OBJECTIVE To establish a stable, useful culture system for human osteoclasts and to investigate the effect of osteoblasts on the differentiation, proliferation and activation of osteoclasts so as to provide a base for the studies on prevention and treatment of osteolysis and osteoporosis. METHODS In the presence of 1,25-(OH)2D3, monocytes abstracted from human bone marrow were cultured in three groups: co-culture of monocytes and osteoblasts, monocytes alone, monocytes with conditional media (CM) of osteoblasts. Differentiation process of the cultured cells was observed under biological microscope. HE staining and tartrate-resistant acid phosphatase (Trap) staining were employed to assay the cultured cells. The resorption pits on bone slices, on which cells were cultured, were observed under scanning electronic microscope (SEM). RESULTS In the group of co-culture of monocytes and osteoblasts, monocytes gradually fused to form multinucleated cells (MNCs), and the MNCs were also indicated in HE staining and Trap staining. The SEM showed a number of resorption pits on bone slices. In the other two groups, Trap-positive MNCs were not obtained, and resorption pits were not observed on bone slices. CONCLUSION In this culture, monocytes obtained from human marrow fused to form multinucleated cells (MNCs) that express the main characteristics of the osteoclast phenotype, such as Trap-positive and the ability to form resorption lacunae when cultured on bone slices. Cell-to-cell contact with osteoblasts was necessary for the differentiation, proliferation and activation of osteoclasts.

Abstract
OBJECTIVE To examine estrogen receptor (ER) in osteoblasts from adult human and to elucidate the mechanism of estrogen in modulating bone metabolism. METHODS The cultured osteoblasts were harvested from bone chips by modified sequential digestive enzyme release and immunohistochemical assay of ER in osteoblasts were carried out in three groups of female adults: normal control (group 1), patients with moderate osteoporosis (group 2) and patients with serious osteoporosis (group 3). The percentages of ER-positive osteoblasts from the three groups were compared by t test. RESULTS The brown marks that indicate ER were found in nuclei and plasma of the osteoblasts, and the percentages of ER-positive osteoblasts among three groups were significantly different. CONCLUSION ERs exist in nuclei and plasma of the osteoblasts. Estrogen may modulate bone metabolism through binding ER in nuclei and plasma of the osteoblasts. The reduction of ER of osteoblasts may play an important role in the pathogenesis of postmenopausal osteoporosis.

Abstract
The self-organizing tree algorithm (SOTA) was recently introduced to construct phylogenetic trees from biological sequences, based on the principles of Kohonen's self-organizing maps and on Fritzke's growing cell structures. SOTA is designed in such a way that the generation of new nodes can be stopped when the sequences assigned to a node are already above a certain similarity threshold. In this way a phylogenetic tree resolved at a high taxonomic level can be obtained. This capability is especially useful to classify sets of diversified sequences. SOTA was originally designed to analyze pre-aligned sequences. It is now adapted to be able to analyze patterns associated to the frequency of residues along a sequence, such as protein dipeptide composition and other n-gram compositions. In this work we show that the algorithm applied to these data is able to not only successfully construct phylogenetic trees of protein families, such as cytochrome c, triosephophate isomerase, and hemoglobin alpha chains, but also classify very diversified sequence data sets, such as a mixture of interleukins and their receptors.
