Abstract
Related studies have shown that ITGB2 mediates mitochondrial glycolytic transformation in cancer-associated fibroblasts and participates in tumor occurrence, metastasis and invasion of cancer cells. Based on these studies, we tried to construct a mitochondrial glycolysis regulatory network and explored its effect on mitochondrial homeostasis and ovarian cancer cells' cancerous characteristics. Our research revealed a distinct increase in the expression of ITGB2 and associated signaling pathway elements (PI3K-AKT-mTOR) in cases of ovarian cancer. ITGB2 might control mTOR expression via the PI3K-AKT pathway, thus promote mitochondrial glycolysis transformation and cell energy supply in ovarian cancer. This pathway could also inhibit mitophagy, maintain mitochondrial stability, and enhance the cancerous characteristics in case of ovarian cancer cells by mediating mitochondrial glycolytic transformation. Thus, we concluded that ITGB2-associated signaling route (PI3K-AKT-mTOR) may contribute to the progression of cancerous traits in ovarian cancer via mediating mitochondrial glycolytic transformation.

Abstract
INTRODUCTION To date, an increasing number of studies have revealed that GP73 may have prognostic value in liver cancer. However, most of the studies evaluated serum GP73, and the results regarding the prognostic value of tGP73 in liver cancer are still controversial. Therefore, in this meta-analysis, we aimed to determine whether tGP73 has any prognostic value in patients with HCC. MATERIALS AND METHODS Relevant publications were searched for in PubMed, EMBASE, OVID, the Cochrane Library, and the Web of Science databases up to March 2023. The hazard ratio (HR) or odds ratio (OR) with corresponding 95% confidence intervals (95% CIs) of eligible studies were assessed by fixed-effects or random-effects models. In addition, subgroup analyses were conducted to investigate the possible causes of heterogeneity, and publication bias analysis was also performed to assess the reliability of the meta-analysis results. RESULTS A total of 10 studies were included. These studies included 1569 HCC patients, and a meta-analysis was performed. The results of our meta-analysis showed that higher GP73 expression levels were significantly associated with poorer OS (HR = 1.87, 95% CI: 1.41-2.48, P < 0.0001, I2 = 58%). However, there was no significant correlation between high GP73 expression and disease-free survival (DFS) (HR: 1.43, 95% CI: 0.93-2.33, P = 0.100). In addition, abnormal GP73 expression was also related to higher tumour tissue differentiation grade (OR = 3.03, 95% CI = 2.01-4.57, P < 0.0001, I2 = 89%), later tumour stage (OR = 5.89, 95% CI = 2.31-14.99, P < 0.0001, I2 = 0%), vascular invasion (OR = 1.72, 95% CI = 1.12-2.64, P = 0.010, I2 = 0%), multiple tumours (OR = 2.44, 95% CI = 1.37-3.68, P = 0.001, I2 = 44%) and early postoperative tumour recurrence (OR = 1.92, 95% CI = 1.10-3.28, P = 0.020, I2 = 62%). CONCLUSIONS The meta-analysis showed that the overexpression of GP73 may be related to a poor prognosis of HCC, and it may also have a predictive effect on the invasion and metastasis of HCC.

Abstract
miR-520a-3p is downregulated and MUC1 is upregulated in AML patients. miR-520a-3p over-expression inhibits AML cell proliferation, accelerates apoptosis, and inhibits AML tumor growth. miR-520a-3p targets MUC1 and negatively regulates its expression. MUC1 knockdown supresses AML cell proliferation and promotes apoptosis. miR-520a-3p overexpression inhibits AML cell proliferation and accelerates cell apoptosis via regulating MUC1/Wnt/β-catenin axis.
Background Acute myeloid leukemia (AML) is one of the familiar malignant tumors in the hematological system. miR-520a-3p is reported to be involved in several cancers’ progression. However, miR-520a-3p role in AML remains unclear. In this study, we aimed to clarify the role and potential mechanism of miR-520a-3p in AML. Methods Cell viability, proliferation, cycle and apoptosis were detected by MTT assay, colony formation assay, flow cytometry, respectively. The levels of PNCA, Bcl-2, Cleaved caspase 3, Cleaved caspase 9 and β-catenin protein were detected by Western blot. Dual-luciferase reported assay was performed to detect the regulation between miR-520a-3p and MUC1. To verify the effect of miR-520a-3p on tumor proliferation in vivo, a non-homogenous transplant model of tumors was established. Results miR-520a-3p expression was down-regulated, and MUC1 expression was up-regulated in AML patients. miR-520a-3p overexpression suppressed THP-1 cell proliferation, induced cell cycle G0/G1 inhibition and promoted apoptosis. miR-520a-3p targeted MUC1 and negatively regulated its expression. MUC1 knockdown inhibited THP-1 cell proliferation and promoted apoptosis. miR-520a-3p overexpression inhibited AML tumors growth. Conclusion Overexpression miR-520a-3p inhibited AML cell proliferation, and promoted apoptosis via inhibiting MUC1 expression and repressing Wnt/β-catenin pathway activation.

Abstract
Objective: To determine whether insulin resistance is associated with all-cause mortality in subjects without diabetes. Methods: A total of 505 participants without diabetes, 198 with normal glucose tolerance (NGT) and 307 with impaired glucose tolerance (IGT), were recruited from the Daqing Diabetes Study. The participants were followed up for 30 years. They were stratified into three groups (tertiles) according to baseline homeostasis model assessment of insulin resistance(HOMA-IR) levels, as the HOMA-IR 0, the HOMA-IR 1 and the HOMA-IR 2 groups, to assess the predictive effect of insulin resistance on risk of all-cause mortality. Results: During the 30-year follow-up, 52, 56 and 78 participants died across the three HOMA-IR groups, respectively. The corresponding mortality per 1 000 person-years (95%CI) were 12.12 (9.56-15.01), 13.10 (10.46-16.03) and 19.91 (16.73-23.15), respectively. Participants in the HOMA-IR 2 group had a significantly higher risk of death than those in the HOMA-IR 0 group after adjustment of age, sex and smoking status (HR=1.97,95%CI 1.38-2.81, P<0.001). Cox analyses showed that a one standard deviation increase in HOMA-IR was associated with a 22% increase in the mortality after adjustment of potential confounders (HR=1.22, 95%CI 1.08-1.39, P=0.002). Conclusions: Insulin resistance is associated with increased risk of all-cause death in Chinese people without diabetes, suggesting that improving insulin resistance could be beneficial for people without diabetic in reducing risk of long-term all-cause mortality.

Abstract
Many circular RNAs (circRNAs) are produced from back-splicing of exons of precursor mRNAs and are generally co-expressed with cognate linear RNAs. Methods for circRNA-specific knockout are lacking, largely due to sequence overlaps between forms. Here, we use base editors (BEs) for circRNA depletion. By targeting splice sites involved in both back-splicing and canonical splicing, BEs can repress circular and linear RNAs. Targeting sites predominantly for circRNA biogenesis, BEs could efficiently repress the production of circular but not linear RNAs. As hundreds of exons are predominantly back-spliced to produce circRNAs, this provides an efficient method to deplete circRNAs for functional study.

Abstract
Based on Yichang health big data platform, 850 608 patients from September 2018 to September 2019 were included in this study. According to the date of birth, the participants were divided into early childhood famine exposure group, fetal famine exposure group and non-famine exposure group. The incidence of adult herpes zoster (HZ) in Yichang city was analyzed, and the correlation between early life famine exposure and adult HZ was analyzed. In 2019, the crude incidence rate of adult HZ in Yichang was 6.83‰. The crude incidence rate of adult HZ in females (7.26‰) was higher than that in males (6.40‰). Compared with the non-famine exposure group, fetal famine exposure was associated with the incidence of adult HZ (OR=1.21; 95%CI: 1.01-1.45, P=0.041). After stratification by sex, fetal famine exposure was only found to be associated with the onset of adult HZ in females (OR=1.28, 95%CI:1.02-1.61, P=0.034).

Abstract
BACKGROUND Congenital coronary artery fistula can lead to symptoms of chest tightness, chest pain, or exertional dyspnea, which is a congenital vascular malformation that should not be ignored. Patients who have such malformations are frequently observed with different concurrent abnormal anatomic structures. Collateral circulation may have a positive effect on improving the patients' symptoms.
CASE SUMMARY A 53-year-old female experienced episodic chest discomfort for the past month with symptoms manifesting when she was agitated or overexerted. After a positive treadmill test, the patient underwent coronary angiography. “Ghostlike” intermittent appearance of coronary ventricular fistula and collateral branching were observed. The patient was diagnosed with a right coronary ventricular fistula and collateral circulation.
CONCLUSION This case shows the likelihood of collateral circulation in patients with coronary artery fistula. This may provide medical staff with novel solutions to treat insufficiency of myocardial blood supply induced by cardiovascular malformations.

Abstract
Single-cell RNA-seq (scRNA-seq) profiles gene expression with high resolution. Here, we develop a stepwise computational method-called SCAPTURE to identify, evaluate, and quantify cleavage and polyadenylation sites (PASs) from 3' tag-based scRNA-seq. SCAPTURE detects PASs de novo in single cells with high sensitivity and accuracy, enabling detection of previously unannotated PASs. Quantified alternative PAS transcripts refine cell identity analysis beyond gene expression, enriching information extracted from scRNA-seq data. Using SCAPTURE, we show changes of PAS usage in PBMCs from infected versus healthy individuals at single-cell resolution.

Abstract
Objective: To explore the relationship between exposure to famine in early life and the risk of hypertension in adulthood. Methods: The medical data of Yichang Health Management Big Data Center from 2018 to 2019 were analyzed. A retrospective cohort study design was adopted, with hypertension as the study outcome, and different life periods exposed to the Great Famine in China were divided into groups. Multivariate logistic regression model was used to analyze the relationship between famine exposure in early life and hypertension in adulthood. At the same time, the interaction between gender and famine exposure was analyzed. Results: The age of 142 016 subjects was (60. 56±4.43). Among them, men accounted for 46.36% (65 845/142 016) and women accounted for 53.64% (76 171/142 016). There are 42 575(29.98%), 19 644(13.83%), 28 405(20.00%), 28 305(19.93%), 23 087 (19.93%) in non-famine exposure group, fetal famine exposure group, early childhood famine exposure group and late childhood famine exposure group, respectively. The prevalence of hypertension was 17.57% (24 947 cases). Multivariate logistic regression model analysis showed that after adjusting for related confounding factors, compared with non-famine exposure group, the risk of hypertension in fetal, early childhood, middle childhood and late childhood famine exposure group was higher and the OR (95%CI) values were 1.16 (1.11-1.22), 1.27 (1.21-1.33), 1.54 (1.47-1.60) and 1.84 (1.76-1.92), respectively. There was an interaction between sex and famine exposure group (P<0.001). The above association is stronger among women than among men. Conclusion: Famine exposure in early life may increase the risk of hypertension in adulthood, and the risk of women is greater than that of men.

Abstract
Objective: To investigate the effect of dexmedetomidine on remifentanil-induced hyperalgesia and its underlying mechanism through a prospective cohort study. Methods: From July 2018 to July 2019, 80 patients who underwent day surgery in Taizhou Central Hospital (including patients with laparoscopic cholecystectomy and oophorocystectomy) were selected, there were 46 males and 34 females with a mean age of (28.8±4.3) years. The patients were divided into dexmedetomidine group and control group with random number table, 40 cases in each group. After anesthesia induction, the dexmedetomidine group was managed with intravenous infusion of dexmedetomidine (1 μg/kg) within 10 minutes, while the control group was treated with an equal volume of normal saline. The patient's general information and the intraoperative data were recorded. The visual analogue scale (VAS) was evaluated before the operation and 1, 6 and 12 h after the surgery. The Von Frey cilia method was conducted to determine the mechanical pain threshold of the patient's non-surgical body parts. The vein blood was extracted at the corresponding time point to evaluate the expression level of miR-183 via the RT-PCR method. The demographic and preoperative parameters were comparable between the two groups. Results: Compared with the control group, the mechanical pain threshold in the dexmedetomidine group increased significantly at 1, 6, and 12 h after surgery (all P<0.05), and the VAS score at the corresponding time point declined significantly (all P<0.05). At the same time points, the serum miR-183 levels in the dexmedetomidine group were all significantly higher than those in the control group after surgery (2.07±0.41 vs 1.68±0.60, 1.99±0.33 vs 1.74±0.54, 1.88±0.36 vs 1.67±0.54, respectively, all P<0.05). Conclusion: A perioperative dose of dexmedetomidine in day surgery can significantly improve the remifentanil-related hyperalgesia, and it may be related to up-regulation of the expression of miR-183 in the blood.

Abstract
We aimed to establish a discriminative gene-expression-based classifier to predict survival outcomes of T-cell lymphoblastic lymphoma (T-LBL) patients. After exploring global gene-expression profiles of progressive (n = 22) vs. progression-free (n = 28) T-LBL patients, 43 differentially expressed mRNAs were identified. Then an eleven-gene-based classifier was established using LASSO Cox regression based on NanoString quantification. In the training cohort (n = 169), high-risk patients stratified using the classifier had significantly lower progression-free survival (PFS: hazards ratio 4.123, 95% CI 2.565-6.628; p < 0.001), disease-free survival (DFS: HR 3.148, 95% CI 1.857-5.339; p < 0.001), and overall survival (OS: HR 3.790, 95% CI 2.237-6.423; p < 0.001) compared with low-risk patients. The prognostic accuracy of the classifier was validated in the internal testing (n = 84) and independent validation cohorts (n = 360). A prognostic nomogram consisting of five independent variables including the classifier, lactate dehydrogenase levels, ECOG-PS, central nervous system involvement, and NOTCH1/FBXW7 status showed significantly greater prognostic accuracy than each single variable alone. The addition of a five-miRNA-based signature further enhanced the accuracy of this nomogram. Furthermore, patients with a nomogram score ≥154.2 significantly benefited from the BFM protocol. In conclusion, our nomogram comprising the 11-gene-based classifier may make contributions to individual prognosis prediction and treatment decision-making.

Abstract
PURPOSE Adults with T-cell lymphoblastic lymphoma (T-LBL) generally benefit from treatment with acute lymphoblastic leukemia (ALL)-like regimens, but approximately 40% will relapse after such treatment. We evaluated the value of CpG methylation in predicting relapse for adults with T-LBL treated with ALL-like regimens. EXPERIMENTAL DESIGN A total of 549 adults with T-LBL from 27 medical centers were included in the analysis. Using the Illumina Methylation 850K Beadchip, 44 relapse-related CpGs were identified from 49 T-LBL samples by two algorithms: least absolute shrinkage and selector operation (LASSO) and support vector machine-recursive feature elimination (SVM-RFE). We built a four-CpG classifier using LASSO Cox regression based on association between the methylation level of CpGs and relapse-free survival in the training cohort (n = 160). The four-CpG classifier was validated in the internal testing cohort (n = 68) and independent validation cohort (n = 321). RESULTS The four-CpG-based classifier discriminated patients with T-LBL at high risk of relapse in the training cohort from those at low risk (P < 0.001). This classifier also showed good predictive value in the internal testing cohort (P < 0.001) and the independent validation cohort (P < 0.001). A nomogram incorporating five independent prognostic factors including the CpG-based classifier, lactate dehydrogenase levels, Eastern Cooperative Oncology Group performance status, central nervous system involvement, and NOTCH1/FBXW7 status showed a significantly higher predictive accuracy than each single variable. Stratification into different subgroups by the nomogram helped identify the subset of patients who most benefited from more intensive chemotherapy and/or sequential hematopoietic stem cell transplantation. CONCLUSIONS Our four-CpG-based classifier could predict disease relapse in patients with T-LBL, and could be used to guide treatment decision.

Abstract
UNLABELLED Loss of bone mineral density and skeletal muscle area are linked in lung transplant patients. This loss is greater in patients with restrictive compared with obstructive lung diseases. INTRODUCTION Sarcopenia and osteoporosis are associated with aging and chronic illnesses and may be linked in patients with advanced lung disease. Pectoralis muscle index (PMI) quantitated on computed tomography (CT) of the chest can be used to measure skeletal muscle mass. This study aimed to determine the relationship of PMI to clinical parameters including bone mineral density (BMD) in candidates for lung transplantation. METHODS A retrospective review of transplant candidates at a single center was performed. Demographic, anthropomorphic, and clinical data were recorded. Pectoralis muscle area (PMA) was determined on an axial slice from a chest CT. PMI was calculated as the PMA divided by height squared. BMD was obtained from routine dual-energy X-ray absorptiometry (DXA) scan. RESULTS In 226 included patients, mean PMI was 8.2 ± 3.0 cm2/m2 in males and 6.1 ± 2.1 cm2/m2 in females. Osteopenia was present in 44.4%, and 23.2% of patients had osteoporosis. Patients with obstructive lung disease had lower body mass index (22.0 ± 4.9 versus 27.9 ± 4.9 kg/m2, p < 0.001), PMI (6.0 ± 2.3 versus 8.2 ± 2.8 cm2/m2, p < 0.001), and BMD (- 2.3 ± 1.1 versus - 1.3 ± 1.1, p < 0.001) compared with patients with restrictive lung disease. PMI was a significant predictor of BMD (β = 0.16, p < 0.001). CONCLUSION The association between muscle area and BMD in lung transplant candidates suggests that similar mechanisms may underlie the development of both. Differences in PMI and BMD in patients with obstructive versus restrictive lung disease may result from differences in respiratory physiology or disease processes.

Abstract
Objective: To determine the opening and closing action of the external muscle, the projection pathway of the axon terminal of trigeminal motor nucleus (Vmo) neuron to the lateral pterygoid muscle was revealed. Methods: In this study, 10 SD rats of 8 weeks old were included. The left lateral pterygoid muscle of SD rats was surgically exposed, and the wound was closed after intramuscular injection of hydroxystilbamidine/fluorogold (FG) 3-5 μl. Seven days after the operation, the experimental animals were perfused, samples collected and sectioned for immunofluorescence staining. After FG injection into the lateral pterygoid muscle, the FG reversed in the Vmo neurons. Results: In the Vmo neurons on the FG injection side (left side), a large number of FG reversed neurons were found in the corpus luteum and dendrites. These neurons were not only distributed in the dorsolateral part of the trigeminal motor nucleus that innervated the closed muscle, but also in the ventral medial portion of the trigeminal nucleus of the open muscle. Conclusions: The neuronal conduction pathway between the Vmo and the lateral pterygoid muscle innervates the lateral pterygoid muscle. The neurons are distributed both in the dorsolateral and in the nucleus of the ventral ventricle. It is concluded that the lateral pterygoid muscle involve in the jaw closing and opening movement.

Abstract
Objective: To explore the influence of lifestyle intervention on long-term diabetes in subjects with impaired glucose tolerance (IGT) returned to normal glucose tolerance (NGT) within 6 years. Methods: A total of 577 subjects (aged 25-74 years old) with IGT in Daqing were enrolled and randomly assigned to control, and diet, exercise and diet plus exercise groups in a six-year intervention trial in 1986. Subjects who were non-diabetic at the end of the intervention were followed up for additional 14 years. Results: Among all the subjects, 41.38% of them who had returned to NGT from IGT within 6 years maintained NGT status after 20 years, and had a lower incidence of diabetes than subjects maintained IGT status (46.55% vs. 75.25%). Of note, in the intervention group, the percentage of participants developed diabetes in the NGT subjects was significantly lower than that in the IGT group (43.71% vs. 76.25%) after 20 years. There was high long-term risk for diabetes in the IGT subjects after the adjustment of age, sex and baseline glucose (HR=1.81, 95%CI 1.27-2.58, P=0.001), whereas in the non-intervention group, no significant difference could be viewed in long-term diabetic risk between subjects maintained IGT status and those returned to NGT (71.43% vs. 65.22%) after adjusting of the same confounders (HR=1.03, 95%CI 0.45-2.35, P=0.94). Conclusions: IGT subjects who had returned to NGT in early years had lower risk for future diabetes than those who remained IGT. However, this beneficial effect could only be viewed in the intervention group, but not in the non-intervention group.

Abstract
Porcine epidemic diarrhea virus (PEDV) is a highly infectious pathogen that can cause severe diseases in pigs and result in enormous economic losses in the worldwide swine industry. Previous studies revealed that PEDV exhibits an obvious capacity for modulating interferon (IFN) signaling or expression. The newly discovered type III IFN, which plays a crucial role in antiviral immunity, has strong antiviral activity against PEDV proliferation in IPEC-J2 cells. In this study, we aimed to investigate the effect of PEDV nucleocapsid (N) protein on type III IFN-λ. We found that the N proteins of ten PEDV strains isolated between 2013 and 2017 from different local farms shared high nucleotide identities, while the N protein of the CV777 vaccine strain formed a monophyletic branch in the phylogenetic tree. The N protein of the epidemic strain could antagonize type III IFN, but not type I or type II IFN expression induced by polyinosinic-polycytidylic acid (poly(I:C)) in IPEC-J2 cells. Subsequently, we demonstrated that the inhibition of poly(I:C)-induced IFN-λ3 production by PEDV N protein was dependent on the blocking of nuclear factor-κB (NF-κB) nuclear translocation. These findings might help increase understanding of the pathogenesis of PEDV and its mechanisms for evading the host immune response.

Abstract
The shells of Chinese chestnuts (Castanea mollissima) are an agricultural residue. This work aimed to evaluate this feasibility of using steam explosion to modify this residue for Cu(II) biosorption from aqueous solutions. Equilibrium, kinetic and thermodynamic parameters were evaluated. The steam-explosion pretreatment increased the surface area of the chestnut shell and exposed more hydroxyl and carboxyl groups, which are binding sites for Cu(II). It changed the sorption from a spontaneous process driven by enthalpy to a nonspontaneous one driven by entropy. It increased the Cu(II) sorption capacity at higher temperatures while it decreased the capacity at lower ones. Compared with untreated chestnut shell, the steam-exploded shell is preferable for Cu(II) sorption at higher temperatures.

Abstract
Circular RNAs (circRNAs) from back-splicing of exon(s) have been recently identified to be broadly expressed in eukaryotes, in tissue- and species-specific manners. Although functions of most circRNAs remain elusive, some circRNAs are shown to be functional in gene expression regulation and potentially relate to diseases. Due to their stability, circRNAs can also be used as biomarkers for diagnosis. Profiling circRNAs by integrating their expression among different samples thus provides molecular basis for further functional study of circRNAs and their potential application in clinic. Here, we report CIRCpedia v2, an updated database for comprehensive circRNA annotation from over 180 RNA-seq datasets across six different species. This atlas allows users to search, browse, and download circRNAs with expression features in various cell types/tissues, including disease samples. In addition, the updated database incorporates conservation analysis of circRNAs between humans and mice. Finally, the web interface also contains computational tools to compare circRNA expression among samples. CIRCpedia v2 is accessible at http://www.picb.ac.cn/rnomics/circpedia.

Abstract
OBJECTIVE To identify the master transcription factors (TF) that might be responsible for the gene expression alteration of OA. METHODS Raw expression data for rat OA model(GSE30322) was downloaded from NCBI GEO database. Microarray data analysis for rat and human was carried out separately using functions from limma packagein R, gene expression was considered as significantly changed between conditions if adjusted P-value<0.05 and the absolute value of fold change>=2. iRegulon was applied to differentially up-regulated and down-regulated genes in OA separately. RESULTS (1)15 TFs, including FOXN4, NANOS1, E2F6, RAD21, MECOM, ETS1, MEF2A, POU2F3, BRCA1, GATA3, ZNF706, ZBTB33, SUZ12, DBP and SETDB1, were identified as the potential master TFs of up-regulated DEGs with statistical significance. (2)12 TFs, including ARID3A, YY1, RDBP, ATF1, CRX, TAF1, XBP1, SOX3, E2F4, PGR, TIMM8A and HOXA2, were identified as the potential master TFs of down-regulated DEGs with statistical significance. CONCLUSIONS The newly identified TFs maybe play important roles in pathogenesis of early experimental osteoarthritis, and our study provides new diagnostic markers or therapeutic targets for OA.

Abstract
Bismuth tellurohalides with Rashba-type spin splitting exhibit unique Fermi surface topology and are developed as promising thermoelectric materials. However, BiTeBr, which belongs to this class of materials, is rarely investigated in terms of the thermoelectric transport properties. In the study, polycrystalline bulk BiTeBr with intensive texture was synthesized via spark plasma sintering (SPS). Additionally, its thermoelectric properties above room temperature were investigated along both the in-plane and out-plane directions, and they exhibit strong anisotropy. Low sound velocity along two directions is found and contributes to its low lattice thermal conductivity. Polycrystalline BiTeBr exhibits relatively good thermoelectric performance along the in-plane direction, with a maximum dimensionless figure of merit (ZT) of 0.35 at 560 K. Further enhancements of ZT are expected by utilizing systematic optimization strategies.

Abstract
Manga are a popular artistic form around the world, and artists use simple line drawing and screentone to create all kinds of interesting productions. Vectorization is helpful to digitally reproduce these elements for proper content and intention delivery on electronic devices. Therefore, this study aims at transforming scanned Manga to a vector representation for interactive manipulation and real-time rendering with arbitrary resolution. Our system first decomposes the patch into rough Manga elements including possible borders and shading regions using adaptive binarization and screentone detector. We classify detected screentone into simple and complex patterns: our system extracts simple screentone properties for refining screentone borders, estimating lighting, compensating missing strokes inside screentone regions, and later resolution independently rendering with our procedural shaders. Our system treats the others as complex screentone areas and vectorizes them with our proposed line tracer which aims at locating boundaries of all shading regions and polishing all shading borders with the curve-based Gaussian refiner. A user can lay down simple scribbles to cluster Manga elements intuitively for the formation of semantic components, and our system vectorizes these components into shading meshes along with embedded Bézier curves as a unified foundation for consistent manipulation including pattern manipulation, deformation, and lighting addition. Our system can real-time and resolution independently render the shading regions with our procedural shaders and drawing borders with the curve-based shader. For Manga manipulation, the proposed vector representation can be not only magnified without artifacts but also deformed easily to generate interesting results.

Abstract
Objective: To investigate the the expression of subchondral bone of Indian hedgehog(Ihh) with early experimental osteoarthritis induced by mechanical stress. Methods: The animals were equally divided into two groups: experimental group(E-group, n=15) and control group(S-group, n=15). The right knee joints of E-group underwent surgery, which involved in both medial collateral ligament (MCL) transaction and medial meniscectomy, while the control group was only carried out with a sham operation.The rats were killed at 1, 2 and 4 weeks postsurgery to obtain the right knee joints. Immunostaining and immunofluorescence double staining were performed to evaluate the expression of Ihh in subchondral bone, respectively. Results: The polynuclear giant cells in the subchondral bone of E-Group expressed Ihh in their cytoplasm 1 and 2 weeks post-surgery, except for 4 week, while those of S-Group appeared negative at all three time points postsurgery. There is statistically difference between the mean density of positive area of Ihh in sections of E-group and S-group both in 1 week (E-group: 0.351+ 0.086, S-group: 0.153±0.017, P<0.05) and 2 weeks (E-group: 0.303±0.026, S-group: 0.176±0.013, P<0.05), but without statistically difference in 4 weeks (E-group: 0.092±0.033, S-group: 0.136±0.014, P>0.05) post surgery. Trap positive giant cells in subchondral bone of E-group were also found Ihh positive, which indicated expression of Ihh in osteoclast . Conclusion: Ihh maybe play an important role in pathogenesis of early experimental osteoarthritis.

Abstract
BACKGROUND Multiple tumor-like ectopic calcifications is a rare syndrome characterized by subcutaneous mass deposits of calcium phosphate in periarticular tissues. Although several cases of the surgical treatment of tumoral calcinosis have been reported, the present case is unique in that multiple ectopic calcifications in subcutaneous tissues were found in a hemodialysis patient who had been operated on a total of five times within a period of 1.5 years. METHODS A hemodialysis 60-year-old male presented with multiple tumor-like ectopic calcifications bilateral in the shoulders, right buttock and right thigh. He had been operated on a total of five times within a period of 1.5 years; the operations included a subtotal parathyroidectomy with parathyroid autotransplantation in the right forearm. RESULTS Complete excisions of the ectopic calcifications were performed in the left shoulder, right buttock and right thigh, without signs of recurrence in the same sites at follow-up. Incomplete excision of the ectopic calcification in the right shoulder resulted in recurrence in the same site, and the patient was operated on two more times 1.5 years following the initial surgery. Subtotal parathyroidectomy with parathyroid autotransplantation decreased serum levels of PTH, but the levels of serum calcium and phosphorus remained unchanged post-surgery, which appeared not to inhibit the recurrence of ectopic calcification in patients with CRF. CONCLUSIONS If conservative therapy failed, then early and complete surgical excision may be a good therapeutic option.

Abstract
Several studies have investigated the associations of the vascular endothelial growth factor (VEGF) gene polymorphisms with the susceptibility to osteosarcoma, while their conclusions are conflicting. This meta-analysis was performed to provide a comprehensive assessment on those associations. Electronic bibliographic databases were searched for potential studies focused on the relationship between VEGF polymorphisms and the susceptibility to osteosarcoma on 10 December 2015. Pooled odds ratios with 95% confidence intervals were conducted to assess the associations. After strict screening process, six articles consisted of 1220 osteosarcoma patients and 1576 controls were selected. The pooled results suggested that VEGF-2578C/A polymorphism was significantly associated with osteosarcoma risk in all genetic models as well as VEGF-634G/C polymorphism. When it came to VEGF+936C/T polymorphism, we detected significant associations under allele contrast, heterozygote, dominant and recessive models. As to VEFG-460T/C polymorphism, significant associations were demonstrated in allele contrast and heterozygote models. With regard to VEGF-1156G/A polymorphism, significant association was observed only in alleles contrast model. However, there was no significant association between VEGF-1612G/A polymorphism and risk of osteosarcoma. This meta-analysis suggests that these polymorphisms comprised of VEGF-2578C/A, VEGF-1156G/A, VEGF+936C/T, VEGF-634G/C and VEGF-460T/C are associated with osteosarcoma risk in Chinese Han population.

Abstract
Background Rabies is very common in People’s Republic of China. Each year thousands of people die because of this disease, but rabies diagnosed in pregnancy is very rare. Case Presentation In this study, we report the case of a pregnant woman who was infected with the rabies virus after a dog bite. The symptoms of rabies appeared in labor and she died after pregnancy. Her baby and husband did not develop the disease. Conclusion The phenomenon that the newborn infant was healthy may be related to the protective role of placenta in resisting the invasion of the rabies virus or the absence of systemic viremia. The prompt administration of vaccines and anti-rabies immunoglobulin to the infant may have also contributed to his survival.

Abstract
Malignant obstructive jaundice comprises a group of diseases that can be caused by primary biliary and extra-biliary carcinomas. Generally, surgical resection is the primary treatment for malignant obstructive jaundice; however, for the patients that are unable to undergo surgery, urgent treatment is required to improve hepatic function. Percutaneous transhepatic biliary drainage (PTBD) and stenting are emerging alternative treatments for malignant obstructive jaundice. PTBD and stenting have exhibited good efficacy for the treatment of malignant obstructive jaundice, with few complications and reduced associated pain.

Abstract
In plants, aquaporins play a crucial role in regulating root water transport in response to environmental and physiological cues. Controls achieved at the post-translational level are thought to be of critical importance for regulating aquaporin function. To investigate the general molecular mechanisms involved, we performed, using the model species Arabidopsis, a comprehensive proteomic analysis of root aquaporins in a large set of physiological contexts. We identified nine physiological treatments that modulate root hydraulics in time frames of minutes (NO and H2O2 treatments), hours (mannitol and NaCl treatments, exposure to darkness and reversal with sucrose, phosphate supply to phosphate-starved roots), or days (phosphate or nitrogen starvation). All treatments induced inhibition of root water transport except for sucrose supply to dark-grown plants and phosphate resupply to phosphate-starved plants, which had opposing effects. Using a robust label-free quantitative proteomic methodology, we identified 12 of 13 plasma membrane intrinsic protein (PIP) aquaporin isoforms, 4 of the 10 tonoplast intrinsic protein isoforms, and a diversity of post-translational modifications including phosphorylation, methylation, deamidation, and acetylation. A total of 55 aquaporin peptides displayed significant changes after treatments and enabled the identification of specific and as yet unknown patterns of response to stimuli. The data show that the regulation of PIP and tonoplast intrinsic protein abundance was involved in response to a few treatments (i.e. NaCl, NO, and nitrate starvation), whereas changes in the phosphorylation status of PIP aquaporins were positively correlated to changes in root hydraulic conductivity in the whole set of treatments. The identification of in vivo deamidated forms of aquaporins and their stimulus-induced changes in abundance may reflect a new mechanism of aquaporin regulation. The overall work provides deep insights into the in vivo post-translational events triggered by environmental constraints and their possible role in regulating plant water status.

Abstract
A yellow, rod-shaped, Gram-negative, facultatively aerobic, gliding bacterium, designed strain P7-3-5T, was isolated from intertidal sand of the Yellow Sea, China. Analysis of 16S rRNA gene sequences revealed that strain P7-3-5T formed a distinct lineage within the family
Flavobacteriaceae
, sharing 94.2–96.9 % sequence similarity with type strains of species of the most closely related genera, including
Hyunsoonleella
,
Jejuia
,
Marinivirga
and
Algibacter
. The strain grew at 4–40 °C and with 0.5–5.0 % (w/v) NaCl. It reduced nitrate to nitrite and hydrolysed gelatin and DNA. The major cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G and anteiso-C15 : 0 and the major respiratory quinone was MK-6. Polar lipids included phosphatidylethanolamine (PE), three unidentified aminolipids (AL1–3) and four unidentified lipids (L1–4). The genomic DNA G+C content of strain P7-3-5T was 32.1 mol%. Data from this polyphasic study suggest that strain P7-3-5T represents a novel species in a new genus in the family
Flavobacteriaceae
, for which the name Arenitalea lutea gen. nov., sp. nov. is proposed. The type strain of Arenitalea lutea is P7-3-5T ( = CGMCC 1.12213T = KACC 16457T).

Abstract
A marine prosthecate bacterium, designated strain P-1 km-3T, was isolated from deep seawater from the Pacific. Cells of strain P-1 km-3T were Gram-stain-negative, aerobic, catalase- and oxidase-positive, dimorphic rods with a single polar prostheca or flagellum. The strain hydrolysed gelatin and grew at 6–40 °C (optimum, 30 °C) and with 0.5–12 % (w/v) NaCl (optimum, 2 %). Phylogenetic analysis of the 16S rRNA gene sequences revealed that strain P-1 km-3T belonged to the family
Hyphomonadaceae
in the class
Alphaproteobacteria
and represented a separate lineage, located between the genera
Oceanicaulis
and
Woodsholea
. Sequence similarities of strain P-1 km-3T with type strains of species of the genera
Oceanicaulis
and
Woodsholea
were 93.2–93.9 %. The predominant cellular fatty acids in strain P-1 km-3T were C18 : 1ω7c, C18 : 0, 11-methyl C18 : 1ω7c, C17 : 0 and C19 : 0 cyclo ω8c. The major respiratory quinone of strain P-1 km-3T was Q-10. The polar lipids of strain P-1 km-3T comprised glucuronopyranosyldiglyceride (GUDG), monoglycosyldiglyceride (MGDG), sulfo-quinovosyl diacylglycerol (SQDG), phosphatidylglycerol (PG), an unidentified phospholipid (PL) and an unidentified lipid (L). The genomic DNA G+C content of strain P-1 km-3T was 66.0 mol%. On the basis of the polyphasic data presented in this study, strain P-1 km-3T is proposed to represent a novel species in a new genus, Marinicauda pacifica gen. nov., sp. nov., within the family
Hyphomonadaceae
. The type strain of the type species is P-1 km-3T ( = KACC 16526T = CGMCC 1.11031T).

Abstract
A Gram-negative, motile, aerobic, oxidase- and catalase-positive rod, designated P10-2-4T, was isolated from an intertidal sand sample collected from a coastal area of Qingdao (Yellow Sea), China. The isolate reduced nitrate to nitrite and grew at 4–33 °C and with 0.5–12 % (w/v) NaCl. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), C18 : 1ω7c and C16 : 0. The major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The major respiratory quinone was Q-8. The genomic DNA G+C content was 45.1 %. Phylogenetic analysis of 16S rRNA gene sequences revealed that strain P10-2-4T belonged to the genus
Neptunomonas
. The isolate shared the highest 16S rRNA gene sequence similarity (98.1 %) with
Neptunomonas japonica
JAMM 0745T and 96.9, 96.5 and 95.9 % sequence similarities with
N. antarctica
S3-22T,
N. concharum
LHW37T and
N. naphthovorans
NAG-2N-126T, respectively, strains of the other three recognized species in the genus. DNA–DNA relatedness between strain P10-2-4T and
N. japonica
JCM 14595T was 35.6 %. Furthermore, strain P10-2-4T could be distinguished from the representatives of the genus
Neptunomonas
by a combination of phenotypic characteristics, such as temperature and NaCl concentration for growth, nitrate reduction, DNase activity and assimilation of substrates. The data from this study suggests that strain P10-2-4T represents a novel species in the genus
Neptunomonas
, for which the name Neptunomonas qingdaonensis sp. nov. is proposed. The type strain is P10-2-4T ( = CGMCC 1.10971T = KCTC 23686T).

Abstract
A Gram-negative, aerobic, non-motile, pink-pigmented and rod-shaped strain, designated ZS3-33(T), was isolated from Antarctic intertidal sandy sediment. The strain grew optimally at 15 °C and with 1.0 % (w/v) NaCl. It reduced nitrate to nitrite and hydrolysed Tween 20. It could not produce bacteriochlorophyll a. The predominant cellular fatty acid was C18 : 1ω7c and the predominant respiratory quinone was Q-10. The major polar lipids were phosphatidylglycerol, phosphatidylcholine, two unidentified aminophospholipids and an unidentified aminolipid. Analyses of 16S rRNA gene sequences revealed that strain ZS3-33(T) belonged to the genus Pseudorhodobacter, showing 97.4 % similarity to the type strain of Pseudorhodobacter ferrugineus and 95.3 % similarity to the type strain of Pseudorhodobacter aquimaris. Levels of gyrB gene sequence similarity between strain ZS3-33(T) and the type strains of P. ferrugineus and P. aquimaris were 87.6 and 81.7 %, respectively. DNA-DNA relatedness between strain ZS3-33(T) and P. ferrugineus DSM 5888(T) was 56.6 %. The genomic DNA G+C content of strain ZS3-33(T) was 57.1 mol%. Based on data from this polyphasic study, strain ZS3-33(T) represents a novel species of the genus Pseudorhodobacter, for which the name Pseudorhodobacter antarcticus sp. nov. is proposed. The type strain is ZS3-33(T) ( = CGMCC 1.10836(T) = KCTC 23700(T)). An emended description of the genus Pseudorhodobacter Uchino et al. 2002 emend. Jung et al. 2012 is also proposed.

Abstract
A Gram-staining-negative, aerobic, motile, oxidase- and catalase-positive, rod-shaped strain, designated ZS2-30(T), was isolated from Antarctic intertidal sandy sediment. The strain grew at 4-35 °C (optimum, 25 °C) and in 0-25% (w/v) NaCl (optimum, 3.0-4.0%). It could reduce nitrate to nitrite and hydrolyse Tween 80. The predominant cellular fatty acids of strain ZS2-30(T) were summed feature 3 (C(16:1)ω7c and/or C(16:1)ω6c), C(16:0), C(18:1)ω9c, C(16:1)ω9c, C(12:0) 3-OH and C(12:0). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified aminophospholipid. The genomic DNA G+C content of strain ZS2-30(T) was 55.8 mol%. Analyses of 16S rRNA gene sequences revealed that strain ZS2-30(T) was affiliated with the genus Marinobacter. It showed highest 16S rRNA gene sequence similarities to the type strains of three species of the genus Marinobacter, namely Marinobacter maritimus (98.3%), Marinobacter psychrophilus (98.1%) and Marinobacter goseongensis (97.1%), but the DNA-DNA relatedness values between strain ZS2-30(T) and the above three species were all lower than 45%. Moreover, strain ZS2-30(T) could be distinguished from closely related species of the genus Marinobacter by various phenotypic properties. Based on this taxonomic study using a polyphasic approach, strain ZS2-30(T) is considered to represent a novel species in the genus Marinobacter, for which the name Marinobacter antarcticus sp. nov. is proposed. The type strain of Marinobacter antarcticus is ZS2-30(T) ( = CGMCC 1.10835(T) = KCTC 23684(T)).

Abstract
Aquaporins are water channel proteins that facilitate passage of water and other small neutral molecules across biological membranes. There are usually a large number of members of this family in higher plants, which exhibit various physiological functions and are regulated in a time-specific and particular mode. We have previously shown that a rice gene, OsPIP2;7, was generally up-regulated in roots but down-regulated in shoots at the early stage of chilling stress. Here, OsPIP2;7 was cloned and proved to be an aquaporin with high activity in Xenopus oocytes. OsPIP2;7 was localized mainly in mesophyll cells of leaves. In roots it was detected in the vascular tissues, epidermis cells and exodermis cells at the elongation zone, as well as in the epidermis cells, exodermis cells and root hair at the maturation zone. Yeast cells overexpressing OsPIP2;7 showed a higher survival rate after freeze-thaw stress. Furthermore, OsPIP2;7 enhanced the transpiration rate and tolerance to low temperature when overexpressed in rice. These results indicated that OsPIP2;7 was involved in rapid water transport and maintenance of the water balance in cells, and ultimately improves the tolerance of yeast and rice to low temperature stress.

Abstract
The vacuole, a multifunctional organelle of most plant cells, has very important roles in space filling, osmotic adjustment, storage and digestion. Previous researches suggested that aquaporins in the tonoplast were involved in vacuolar functions. The rice genome contains 33 aquaporin genes, 10 of which encode tonoplast intrinsic proteins (TIPs). However, the function of each individual TIP isoform and the integrated function of TIPs under various physiological conditions remain elusive. Here, five rice TIP members were characterized with water and/or glycerol transport activities using the Xenopus oocyte expression system. OsTIP1;2, OsTIP2;2, OsTIP4;1 and OsTIP5;1 possessed water transport activity. OsTIP1;2, OsTIP3;2 and OsTIP4;1 were demonstrated with glycerol transport activity. Rice TIP expression patterns under various abiotic stress conditions including dehydration, high salinity, abscisic acid (ABA) and during seed germination were investigated by real-time PCR. OsTIP1s (OsTIP1;1 and OsTIP1;2) were highly expressed during seed germination, whereas OsTIP3s (OsTIP3;1 and OsTIP3;2) were specifically expressed in mature seeds with a decrease in expression levels upon germination. The results of this research provided a functional and expression profiles of rice TIPs.

Abstract
To select the MHC-I-binding epitope-rich sequence of mice telomerase reverse transcriptase (mTERT) and study the antitumor immune response induced by truncated TERT through mRNA-transfected dendritic cells (DCs) immunization in mice. The MHC-I-binding epitopes of TERT were predicted using bioinformatics software. The selected sequence of TERT (Truncated mTERT, TERT(t), mTERT cDNA 1776 bp-2942 bp encoding 584 aa-969 aa) was cloned from B16 mouse melanoma cells and inserted into pBluescriptIIKS(+) plasmid downstream of the T7 promoter. TERT(t) RNA was prepared through in vitro transcription. Bone marrow-derived DCs were electroporated with TERT(t) RNA and used to immunize syngeneic naïve mice. The quantity and cytotoxic activity of TERT-specific cytotoxic T lymphocytes (CTLs) in mice spleen were evaluated using IFN-gamma enzyme-linked immunospot (ELISPOT) and Lactate dehydrogenase release assay. The immunoprophylactic effects against TERT positive tumor induced by TERT(t) RNA transfected DC in vivo were evaluated through an immunized-challenged mouse model. TERT(t) was cloned and in vitro transcribed into TERT(t) mRNA. As shown in FCM analysis, the efficiency of DC electroporation is 35.1% (29.7-41.2%). After electroporation, a subtle increase of costimulator and MHC-II molecules were expressed on the cell surface. Immunization of TERT(t) mRNA transfected DCs induced IFN-gamma-secreting CTLs which manifested specific cytotoxic activity against TERT-positive target cells. In a cancer mouse model, vaccination of TERT(t) mRNA-transfected DCs suppressed the growth of TERT positive tumors (p=0.001) and prolong the survival time of tumor-bearing animals (p=0.029). TERT(t) evokes an antitumor immune response in vivo which is targeted to TERT. TERT(t) can be used as an antigeneic sequence to produce anti-TERT tumor vaccine.

Abstract
AIM: To explore the origin for cavernous hemangioma of the liver (CHL) from the angle of ultramicrostructure, and probe the relationship between CHL ultramicrostructure and the clinical characteristics.
METHODS: A total of 8 CHL samples were selected, 1 of which 1 was prepared using routine method, while the other 7 samples was firstly stained by scytodepsic acid before routine management. After the ultrathin sections were prepared by LKB-V ultramicrotome, transmission electron microscope H-600 and JEOL-100SX and scanning electron microscope KYKY-2000 were used to observe the changes of tissue ultrastructure.
RESULTS: In CHL samples, endothelial cell monolayer covered the inner wall of blood sinus which was circuitous and showed labyrinth-like structure. The normal endothelial cells were thin and flat with pinocytotic vesicle, microfilament and fewer cell organelles. There were tight and bridge corpuscle junction. Elastic fibers were located under the endothelial cells, while collagenoblasts and smooth muscle cells were observed in tunica media. Collagen fibers were rich in tunica media and theca externa. These structures were similar to those of arteriole. The endothelial cells of CHL tissues were swelled with nucleoli moving aside, and pillar-like blood sinus existed. Cystoid changes of rough endoplasmic reticulum lasted till the necrosis of endothelial cells occurred. A great amount of collagen fibers proliferated in interstitial substance, which divided the elastic fibers and filled the blood sinus cavity in the position of necrotic endothelial cells through fibrosis. There was no normal hepatic cells and sinus hepaticus in CHL tissues. There were no hepatic lobules in CHL, and double blood-supply system didn't exist.
CONCLUSION: CHL is caused by vascular malformation of liver arteriole, and the blood-supply of CHL is through artery. Circuitous and labyrinth-like structure of the blood sinus cavity can elucidate the characteristics of its imaging results, including hepatic angiography and computed tomography. Anaplasia of endothelial cells and proliferation of collagen fibers in interstitial substance leads to the fibrosis and analosis of CHL, which is the main mechanism of few natural disruptions in CHL.

Abstract
AIM: To study whether heat-shocked tumor cells could enhance the effect of tumor cell lysate-pulsed dendritic cells (DCs) in evoking anti-tumor immune response in vivo.
METHODS: Mouse undifferentiated colon cancer cells (CT-26) were heated at 42 °C for 1 h and then frozen-thawed. The bone marrow-derived DCs pulsed with heat-shocked CT-26 cell lysate (HSCT-26 DCs) were recruited to immunize syngeneic naïve BALB/c mice. The cytotoxic activity of tumor specific cytotoxic T lymphocytes (CTLs) in mouse spleen was evaluated by IFN-enzyme-linked immunospot (ELISpot) and LDH release assay. The immunoprophylactic effects induced by HSCT-26 DCs in mouse colon cancer model were compared to those induced by single CT-26 cell lysate-pulsed DCs (CT-26 DCs) on tumor volume, peritoneal metastasis and survival time of the mice.
RESULTS: Heat-treated CT-26 cells showed a higher hsp70 protein expression. Heat-shocked CT-26 cell lysate pulsing elevated the co-stimulatory and MHC-II molecule expression of bone marrow-derived DCs as well as interleukin-12 p70 secretion. The IFN-γ secreting CTLs induced by HSCT-26 DCs were significantly more than those induced by CT-26 DCs (P = 0.002). The former CTLs’ specific cytotoxic activity was higher than the latter CTLs’ at a serial E/T ratio of 10:1, 20:1, and 40:1. Mouse colon cancer model showed that the tumor volume of HSCT-26 DC vaccination group was smaller than that of CT-26 DC vaccination group on tumor volume though there was no statistical difference between them (24 mm3 vs 8 mm3, P = 0.480). The median survival time of mice immunized with HSCT-26 DCs was longer than that of those immunized with CT-26 DCs (57 d vs 43 d, P = 0.0384).
CONCLUSION: Heat-shocked tumor cell lysate-pulsed DCs can evoke anti-tumor immune response in vivo effectively and serve as a novel DC-based tumor vaccine.

Abstract
AIM To investigate the results of treating short bowel syndrome with an early living related small bowel transplantation (SBT). METHODS A 17-year-old boy with a 20-cm-long residual intestine due to necrotic volvulus received an early living related SBT from his mother. Donor-specific blood transfusion was performed for 8 weeks before transplantation, each time for 50 mL every week. Cytomegalovirus status in both donor and recipient was negative. A 160-cm distal ileal segment was removed from the donor. The graft ilecolic artery and vein were anastomosed to the recipient's infrarenal aorta and caval vein. The proximal end of the graft was anastomosed end-to-end to the residual recipient jejunum; the distal anastomosis, between the distal end of the graft and transverse colon. An ileostomy was also performed. Immunosuppression, infection prophylaxis, and antithrombotic and nutrition support were given postoperatively. RESULTS The donor had an uneventful recovery. No technical complications were observed. The recipient was alive and well at 31 weeks after the operation. No graft rejection or infection was observed. He was off TPN 8 weeks after the operation and took low-fat food. The D-xylose test in the recipient was almost normal. CONCLUSIONS Early living related small intestine transplantation is a good treatment for short bowel syndrome.
