Abstract
Objective: To explore the advantage of Fuzheng Huayu capsule in patients with hepatitis B cirrhosis based on neutrophil/lymphocyte ratio (NLR) risk stratification in reducing the incidence of hepatocellular carcinoma (HCC). Methods: 916 cases diagnosed with hepatitis B cirrhosis and followed up for five years from January 2011 to January 2016 at Beijing Ditan Hospital Affiliated with Capital Medical University were included, and clinical data were collected. Patients were divided into a combination group and an antiviral group according to whether they were treated with anti-fibrosis for≥6 months. The antiviral group was treated with entecavir or tenofovir disoproxil, while the combination group was treated with Fuzheng Huayu capsules based on the antiviral therapy. The incidence of HCC was compared between the two groups of patients within five years. The advantaged groups treated with Fuzheng Huayu capsule were explored based on NLR risk stratification. The independent sample t-test and Mann-Whitney U test were used to compare measurement data between two groups. Categorical variable data were compared using either the χ(2) test or Fisher's exact probability method. The incidence of HCC in the two groups of patients was analyzed through the Kalplan-Merier curve and compared using the log-rank method. Results: There were 299 (32.6%) and 617 (67.4%) cases in the combined group and the antiviral group, respectively. A total of 154 (16.8%) patients developed HCC during the follow-up period. The five-year cumulative incidence of HCC in the combination group was lower than that in the antiviral group (10.7% vs. 19.8%, χ(2) = 11.848, P = 0.000 4). Patients with baseline NLR>3 had an increased risk of HCC. According to NLR risk stratification, there were 191 cases in the low-risk group (NLR<1.4), 462 cases in the medium-risk group (NLR1.4 ~ 3.0), and 263 cases in the high-risk group (NLR>3). Among medium to high-risk patients, the incidence of HCC was significantly reduced in the combination group (11.5% vs. 19.4%, χ(2) = 4.519, P = 0.029; 13.2% vs. 26.2%, χ(2) = 5.258, P = 0.019), while there was no statistically significant difference in the incidence of HCC among the low-risk group (P = 0.38). Conclusion: Compared with antiviral treatment alone, Fuzheng Huayu capsules combined with antiviral treatment can better reduce the five-year HCC incidence rate in patients with hepatitis B cirrhosis. Medium-and high-risk patients with NLR stratification are the most advantageous population to be treated with Fuzheng Huayu capsules.

Abstract
How to promote high-quality wound healing is a common problem for plastic surgery and burn physicians. In recent years, numerous animal studies have demonstrated that mesenchymal stem cell-derived exosomes promote wound repair through multiple mechanisms and are promising cell-free therapeutic agents with broad prospect of application. How to enhance the therapeutic efficacy of exosomes, optimize their drug delivery strategy, and improve their biological properties are the challenges to be overcome in order to move from basic research to clinical application of exosome therapy for wound repair. This article focuses on methods to improve the wound repair potential of mesenchymal stem cell-derived exosomes, and reviews the recent research advances on improving the therapeutic efficacy of mesenchymal stem cell-derived exosomes in wound repair from three aspects, including pretreatment of parental mesenchymal stem cells, hydrogel bio-scaffold loaded with exosomes, and engineered exosomes, to provide a reference for further clinical studies.

Abstract
Objective: To investigate the efficacy of debridement, decompression, interbody fusion and percutaneous screw internal fixation under the unilateral biportal endoscopy (UBE) combined with drug chemotherapy for thoracic and lumbar tuberculosis. Methods: A follow-up study. The clinical data of 9 patients who underwent UBE debridement, decompression, interbody fusion and percutaneous screw internal fixation combined with drug chemotherapy for thoracic and lumbar tuberculosis at the First Affiliated Hospital of Xinjiang Medical University from September 2021 to February 2022 were retrospectively analyzed. There were 4 males and 5 females, aged (52.4±13.5) years (ranged 27-71 years). All patients were given quadruple (isoniazid+rifampicin+pyrazinamide+ethambutol) anti-tuberculosis drugs chemotherapy for 2 to 4 weeks before surgery. The operation time, intraoperative blood loss, postoperative drainage volume, ambulation time, postoperative hospital stay and complications were recorded. The visual analog scale (VAS) of pain, Oswestry disability index (ODI), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in the patients were compared before and after the surgery. The degree and improvement of spinal cord injury before and after surgery were assessed according to the American Spinal Injury Association (ASIA) neurological classification; and the Cobb angle was measured before and after surgery to assess kyphotic deformity and correction. X-ray or CT was reviewed at 6 months postoperatively and at the final follow-up, and surgical segmental fusion was evaluated using Bridwell grading criteria. Results: All patients completed the surgery successfully and were followed up for (14.6±1.9) months. The operation time was (182.2±27.5) minutes, the intraoperative blood loss was (222.2±66.7) ml, postoperative drainage volume was (43.3±17.0) ml, the ambulation time was (1.9±0.8) days, postoperative hospital stay was (5.9±1.5) days. Complications occurred in 2 patients (2/9), including 1 case of procedure-related complication. ESR and CRP returned to normal level at the 6-month postoperative follow-up. The VAS score and ODI were significantly improved when compared with those before the operation at each postoperative follow-up time point, and the differences were all statistically significant (all P<0.05). All patients were classified as ASIA grade E at the last follow-up. The postoperative Cobb angle decreased from 14.44°±2.07° to 9.00°±2.29°, and there was no significant loss of angle at the last follow-up. At the 6-month postoperative follow-up, 5 cases (5/9) were classified as Bridwell grade Ⅰ, 2 cases (2/9) as grade Ⅱ, and 1 case (1/9) as grade Ⅲ and Ⅳ, respectively; and all the patients were classified as grade Ⅰ at the last follow-up. Conclusion: Combined with drug chemotherapy, UBE debridement, decompression, interbody fusion and percutaneous screw internal fixation is a safe, feasible and effective therapy for thoracic and lumbar tuberculosis.

Abstract
PURPOSE Five strategies were recommended by the American Association of Clinical Endocrinologists/American College of Endocrinology (AACE/ACE) guidelines for the treatment of postmenopausal osteoporosis (PMO) patients with a very high fracture risk. We aimed to assess their cost-effectiveness in the United States (US). METHODS A microsimulation Markov model was created to compare the cost-effectiveness of five treatment strategies, including zoledronate, denosumab, abaloparatide, teriparatide, and romosozumab in PMO patients with a recent fracture from the healthcare perspective of the US. The data used in the model were obtained from published studies or online resources. Base-case analysis, one-way deterministic sensitivity analysis (DSA) and probability sensitivity analysis (PSA) were conducted for 65-, 70-, 75-, and 80-year-old patients. RESULTS In base case, at 65 years, zoledronate was the cheapest strategy. The incremental cost-effectiveness ratios (ICER, which represent incremental costs per QALY gained) of denosumab, teriparatide, abaloparatide, and romosozumab against zoledronate were $13,020/QALY (quality-adjusted years), $477,331 /QALY, $176,287/QALY, and $98,953/QALY, respectively. Under a willing-to-pay (WTP, which means the highest price a consumer will pay for one unit of a good of service) threshold of $150,000/QALY, denosumab and romosozumab were cost-effective against zoledronate. The PSA results showed that denosumab was the most cost-effective option with WTP thresholds of $50,000/QALY, $100,000/QALY and $150,000/QALY. The results were similar in other age groups. The DSA results indicated that the most common parameters that have important influence on the outcome were drug persistence, incidence of adverse events, the efficacy of drugs on hip fractures and the cost of the drug. CONCLUSION AND RELEVANCE Among PMO patients with a very high fracture risk in the US, zoledronate is the cheapest strategy and denosumab is the most cost-effective choice among these five strategies.

Abstract
The current study aimed to investigate the clinical feasibility of microscopic resection of hemilateral tuberculum sellae meningiomas (TSM) via the contralateral eye brow arch approach. The clinical data of 34 patients with TSM who underwent microsurgery from January 2016 to June 2021 in the Neurosurgery Department of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine and the First Affiliated Hospital of Henan University were collected and reviewed. The postoperative visual acuity improvement rate was 88.5% (23/26), and the total tumor resection rate was 88.2% (30/34); the postoperative visual acuity improvement in patients with total tumor resection was better than that of patients with partial resection [90.9% (20/22) vs 3/4]. Meanwhile, the postoperative visual acuity improvement in patients with the superior optic nerve and laterl-superior optic nerve was better than that of patients with the lateral optic nerve type (12/14, 8/8 vs 3/4). Supraorbital skin numbness occurred in 3 cases after operation, and the symptoms disappeared during follow-up; 2 cases had mild disturbance of hormone level, and urine output of 2 cases increased after operation, which returned to normal level after symptomatic treatment; 1 case had subcutaneous effusion which was absorbed after treatment. There were no complications such as olfactory disturbance and intracranial infection. During follow-up for 3-60 (33±6) months, recurrence occurred in 2 cases and reoperation was performed. For the hemilateral TSM, according to the preoperative evaluation of the origin of the TSM and the side with visual impairment, the contralateral eyebrow approach is selected to fully expose the tumor base below the optic nerve. It is beneficial to fully resect the tumor under direct vision, and the symptoms of postoperative visual impairment are significantly improved, indicating that the current surgical method can be used in the clinical setting.

Abstract
Objectives: To analyze the causes of a foodborne outbreak in rural areas of Xinjiang between April 2 and April 5 in 2016. Methods: Cases and the relevant background information were obtained by consulting outpatient records of local health centers and regional people's hospitals and interviewing doctors and residents. All samples were collected by the laboratory test through epidemiological and food hygiene investigations. The χ2 test (Fisher's exact probability method) was used to compare differences in incidence rates. Molecular typing, virulence genes and single nucleotide polymorphisms (SNPS) were analyzed by using Pulsed Field Gel Electrophoresis (PFGE) and Whole Genome Sequencing (WGS). Results: A total of 142 cases were found in this study, with incidence rate at 5.7‰ (142/24 979). Among all cases, the main symptoms were nausea (94%), vomiting (92%) and abdominal pain (67%), and the incubation period was about 2 h (1-7.5 h). There were 16 Staphylococcus aureus isolates identified and all of them could produce A+C+E mixed enterotoxin. PFGE showed 100% homology. WGS further revealed that there were 9 and 1 strains contained by Sequence Type 1 (ST1) and ST5405, respectively. All ST1 strains were in the same clade on the genome tree. Among these, 7 strains shared close proximity (74 SNPs) and 2 strains shared close relationships as well (127 SNPs). The S. aureus isolates that caused the outbreak were introduced by a mutant isolate from the milk supply station. Conclusions: This foodborne outbreak was mainly caused by Staphylococcus aureus contamination.

Abstract
Objective: To collate and analyze the screening results of high-risk lung cancer populations in communities in Nanchang from 2018 to 2019, and to explore the lung-positive nodules and risk factors for lung cancer. Methods: Data of the screening subjects in 8 administrative districts and 15 street health service centers in Nanchang city, Jiangxi province from November 2018 to October 2019 were collected, people at high risk of lung cancer was assessed, clinical screening of high-risk groups of lung cancer was conducted by low-dose helical computed tomography (LDCT), and risk factors for suspected lung cancer and lung-positive nodules were analyzed. Results: Of the 25 871 people participated in screening, 5 220 were at high risk for lung cancer and 15 374 without other malignant tumors were at high risk. There were 2 417 cases participated in clinical LDCT screening, including 193 cases of lung-positive nodules, 67 cases of suspected lung cancer, 912 cases of other lung diseases, the positive rate of lung cancer or lung-positive nodules was 10.76% (260/2 417). Univariate analysis showed that age, coarse grain intake, oil intake, housing heating, passive smoking, alcohol consumption and mental trauma were associated with positive pulmonary nodules or lung cancer (all P<0.05). Multivariate analysis showed that gender, age, housing heating, smoking and drinking were related to the occurrence of lung nodules or lung cancer (all P<0.05). Conclusions: Men are more likely to develop lung cancer or lung-positive nodules than women. The age is an independent risk factor for lung-positive nodules or lung cancer. In a certain range, age will increase the incidence of lung cancer, housing heating may be the protective factor for lung cancer, while smoking and drinking are risk factors.

Abstract
Objective: To explore the effect and possible mechanism of circ_0023990 on the radiosensitivity of thyroid cancer cells. Methods: qRT-PCR was used to detect the expression of circ_0023990 in the cancer tissues of 55 patients with thyroid cancer and thyroid cancer cell lines (TPC-1, KTC-1, FTC-133 and CAL-62), and the relationship between the expression of circ_0023990 in cancer tissues and the clinical characteristics of the patients were analyzed. Thyroid cancer cells TPC-1 and KTC-1 were divided into sh-circ_0023990 group, sh-NC group, sh-circ_0023990+anti-miR-873-5p group, sh-circ_0023990+anti-miR-NC group, miR-873-5p group, miR-NC group, miR-873-5p+pcDNA-ANXA2 group and miR-873-5p+pcDNA group, and then clone formation experiment was used to detect cell radiosensitivity. After each group of cells was irradiated with 4Gy radiation, the expression of γH2AX protein in the cells was detected by Western Blot. The dual luciferase reporter gene experiment verified the targeting relationship between circ_0023990 and miR-873-5p or miR-873-5p and ANXA2. Results: The expression of circ_0023990 in thyroid cancer tissues was higher than that in normal tissues (2.15±0.09 vs. 0.97±0.05, P<0.05), and its expression was closely related to tumor size, lymph node metastasis and TNM staging of patients with thyroid cancer (P<0.05). The expression of circ_0023990 in thyroid cancer cell lines (TPC-1, KTC-1, FTC-133 and CAL-62) were higher than that of normal thyroid cells HTori-3 (3.16±0.38, 2.63±0.28, 1.82±0.24, 1.71±0.22 vs. 1.00±0.10, all P<0.05). The survival scores of TPC-1 and KTC-1 cells in the sh-circ_0023990 group were significantly lower than those in the sh-NC group (P<0.05), and the sensitization ratios were 2.482, 1.643; The survival scores of TPC-1 and KTC-1 cells in the sh-circ_0023990+anti-miR-873-5p group were higher than those in the sh-circ_0023990+anti-miR-NC group (P<0.05), and the sensitization ratios were 0.305, 0.441, respectively. The survival scores of TPC-1 and KTC-1 cells in the miR-873-5p group were lower than those in the miR-NC group (P<0.05), and the sensitization ratios were 2.044, 1.653 respectively. The survival scores of TPC-1 and KTC-1 cells in the miR-873-5p+pcDNA-ANXA2 group was higher than that in the miR-873-5p+pcDNA group (P<0.05), and the sensitization ratios were 0.496, 0.686, respectively. The expression of γH2AX protein in TPC-1 and KTC-1 cells of the 4 Gy+sh-circ_0023990 group were higher than that in the 4 Gy+sh-NC group (2.68±0.27 vs. 1.87±0.25, 2.46±0.19 vs. 1.77±0.14; all P<0.05), but the expression of γH2AX protein in TPC-1 and KTC-1 cells of the 4 Gy+sh-circ_0023990+anti-miR-873-5p group were lower than that in the 4 Gy+sh-circ_0023990+anti-miR-NC group (1.13±0.09 vs. 1.69±0.09, 1.11±0.08 vs. 1.60±0.08; both P<0.05). The expression of γH2AX protein in TPC-1 and KTC-1 cells in the 4 Gy+miR-873-5p group were higher than that in the 4 Gy+miR-NC group (2.35±0.16 vs. 1.84±0.14, 2.26±0.12 vs. 1.77±0.13; both P<0.05), but the expression of γH2AX protein in TPC-1 and KTC-1 cells of the 4 Gy+miR-873-5p+pcDNA-ANXA2 group were lower than that in the 4 Gy+miR-873-5p+pcDNA group (1.96±0.12 vs. 2.41±0.12, 1.92±0.07 vs. 2.28±0.12; both P<0.05). circ_0023990 targeted the negative regulation of miR-873-5p, and ANXA2 was the target gene of miR-873-5p. Conclusion: circ_0023990 was highly expressed in thyroid cancer tissues and cell lines, and it may promote the radiotherapy resistance of thyroid cancer cells in vivo through regulating miR-873-5p/ANXA2 axis.

Abstract
Objective: To investigate the effect of anti-liver fibrosis treatment on the occurrence of liver cancer in patients with hepatitis B-related liver cirrhosis within three years. Methods: 1,049 cases with hepatitis B-related liver cirrhosis who were hospitalized in Beijing Ditan Hospital affiliated to Capital Medical University from October 2008 to August 2016 were enrolled. Clinical data were collected, and COX regression analysis was used to find the independent influencing factors for the occurrence of liver cancer in patients with hepatitis B-related liver cirrhosis within three years. According to whether the patients had received anti-liver fibrosis treatment for ≥ 6 months, they were divided into combination and antiviral group. There were 388 cases in combination group and 661 cases in antiviral group. In addition, the combination group received anti-liver fibrosis therapy with Chinese patent medicine on the basis of antivirus, and the antiviral group received antiviral treatment. The incidence of liver cancer within three years were compared between the two groups, and the incidence of liver cancer in patients with different Child-Pugh grades and mPAGE-B risks was further analyzed. The independent samples t-test, Mann Whitney U test, χ2 test or Fisher's exact probability method were used for data comparison. Results: Anti-liver fibrosis treatment was an independent protective factor to prevent liver cancer in patients with hepatitis B-related liver cirrhosis within 3 years (P < 0.05). The incidence of liver cancer in the combination group was lower than antiviral group within 3 years (10.3% vs. 15.4%, χ (2) = 5.480, P < 0.05). Child-Pugh stratified analysis showed that the risk of liver cancer was significantly reduced in Child-Pugh grade A patients (6.7% vs. 12.6%, χ (2) = 2.857, P = 0.040). Among high-risk patients with mPAGE-B, the incidence of liver cancer was significantly lower in combination group than control group (13.7% vs. 19.9%, χ (2) = 6.671, P = 0.031). Conclusion: Compared to antiviral therapy alone, combined anti-liver fibrosis and antiviral therapy can reduce the liver cancer occurrence risk in patients with hepatitis B-related liver cirrhosis for 3 years. Patients with Child-Pugh grade A and high-risk group by mPAGE-B scores are the dominant population to receive treatment.

Abstract
OBJECTIVE The aim of this study was to investigate the long non-coding RNA (lncRNA) HULC in promoting angiogenesis after myocardial infarction (MI) and to further investigate its possible mechanism. MATERIALS AND METHODS Twenty-four male Sprague Dawley (SD) rats were randomly divided into two groups, namely, operation group and control group. The rats in the operation group were induced by ligation of the left anterior descending coronary artery, while those in control group received the same surgery without ligating the blood vessels. Seven days after the operation, the myocardial tissues of rats were collected to detect HULC expression by quantitative real-time polymerase chain reaction (RT-PCR). At the same time, the expression of HULC in primary myocardial cells and cardiac microvascular endothelial cells were induced by hypoxia. A hypoxia model was constructed in HUVEC cells, and the effects of HULC were explored by RT-PCR, Western blot Technology (WB), Cell Counting Kit-8 (CCK8) assay, EdU staining, Tube-like structure formation experiments. Thereafter, HULC downstream miRNAs were verified by Luciferase, pull-down, and RNA IP experiments. Similarly, the effects of miR-29b on HUVEC were verified by RT-PCR, WB, CCK8 assay, EdU staining, and tube-like structure formation experiments, respectively. RESULTS RT-PCR detection results showed that the expression of HULC in myocardial tissues was down-regulated after MI, and the expression of HULC in cardiac microvascular endothelial cells was decreased under hypoxia-induced inflammation. In addition, the overexpression of HULC in HUVEC cells could inhibit the expressions of inflammatory factors (IL-1, IL-6 and IL-8) and promote angiogenesis (increased cell viability, increased tube-like structure formation, and increased cell proliferation). Through Dual-Luciferase reporter gene experiments, it was found that HULC could directly target miR-29b. At the same time, miR-29 overexpression significantly reversed the effects of HULC on cell viability, pro-inflammatory cytokines, and angiogenesis. CONCLUSIONS LncRNA HULC protects HUVEC cells from hypoxia-induced inflammation damage by interacting with miR-29b and inhibiting its expression, and it can also promote angiogenesis.

Abstract
OBJECTIVE MicroRNAs (miRNAs) have been demonstrated to be involved in the pathogenesis of various human cancers, including oral squamous cell carcinoma (OSCC). Here, we designed this study to explore the potential effect of miR-1290 on tumorigenesis of OSCC. PATIENTS AND METHODS The expressions of miR-1290 and cyclin G2 (CCNG2) in OSCC were observed by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Dual-Luciferase Reporter Assay was performed to confirm the relationship between miR-1290 and CCNG2. The functions of miR-1290 and CCNG2 were analyzed using transwell assay. The Western blot analysis was used to detect epithelial-mesenchymal transition (EMT). RESULTS Upregulation of miR-1290 and downregulation of CCNG2 were identified in OSCC. And upregulation of miR-1290 was associated with clinicopathological characteristics and poor prognosis in OSCC patients. Moreover, the downregulation of miR-1290 inhibited cell metastasis and EMT in OSCC cells. Furthermore, CCNG2 was a direct target of miR-1290. Its expression was inversely regulated by miR-1290 in OSCC cells. At the same time, the suppressive effect of CCNG2 was observed in OSCC. Furthermore, overexpression of CCNG2 weakened the promoted effect of miR-1290 on cell metastasis in OSCC. CONCLUSIONS MiR-1290 promoted cell metastasis and EMT, inhibiting CCNG2 expression in OSCC.

Abstract
OBJECTIVE To explore the regulatory role of PLZF in the malignant phenotype of non-APL acute myeloid leukemia (AML) and its underlying mechanism. MATERIALS AND METHODS The expression level of PLZF in AML cell lines KG-1a, HL-60, OCI-AML3, THP-1 and K562 was detected by quantitative Polymerase Chain Reaction (qPCR) and Western blot, respectively. Subsequently, THP-1 cells were divided into mock group (no treatment), scramble group (transfection with scramble shRNA) and shPLZF group (transfection with shPLZF). THP-1 cell line stably expressing shPLZF was constructed, followed by determination of its transfection efficiency by qPCR and Western blot, respectively. The proliferation and colony formation of THP-1 cells were accessed using CCK-8 (cell counting kit-8) assay and colony formation assay, respectively. The apoptotic rate in THP-1 cells was determined using flow cytometry. Protein levels of apoptosis-related genes in THP-1 cells were detected by Western blot. Finally, protein levels of AKT, Foxo3a, pAKT and pFoxo3a were detected by Western blot as well. RESULTS Both mRNA and protein levels of PLZF were relatively high in THP-1 cells, and were selected for the following experiments. After construction of THP-1 cell line stably expressing shPLZF, proliferative rate and colony formation abilities increased in the shPLZF group compared with the mock group and the scramble group. We found a decreased apoptotic rate, downregulated Bax and upregulated Bcl-2 in the shPLZF group than those of the mock group and scramble group. Phosphorylation levels of AKT and Foxo3a increased after interference with PLZF, whereas no significant changes in total levels of AKT and Foxo3a were observed. CONCLUSIONS PLZF inhibits the malignant phenotype of AML by regulating the AKT/Foxo3a pathway.

Abstract
OBJECTIVE The aim of this study was to elucidate the expression pattern and potential function of LINC01116 in regulating the progression of osteosarcoma. PATIENTS AND METHODS Expression levels of LINC01116 in osteosarcoma tissues (n=52) and adjacent normal tissues (n=52) were detected by quantitative Real-time polymerase chain reaction (qRT-PCR). Survival analysis and univariate analysis were performed in osteosarcoma patients based on the relative expression levels of LINC01116 and clinical data. Overexpression or silence of LINC01116 in osteosarcoma cells was achieved by transfection of plasmid complementary deoxyribonucleic acid (pcDNA)-LINC01116 or si-LINC01116, respectively. Subsequently, the regulatory effects of LINC01116 on cellular behaviors of osteosarcoma cells were examined by cell counting kit-8 (CCK-8), transwell and flow cytometry. Meanwhile, the potential mechanism of LINC01116 in regulating the progression of osteosarcoma was explored by RNA binding protein immunoprecipitation (RIP), chromatin immunoprecipitation (ChIP) and Western blot. Potential target genes in osteosarcoma were searched, and their functions were clarified through a series of rescue experiments. RESULTS LINC01116 expression in osteosarcoma tissues was significantly higher than adjacent normal tissues. The expression of LINC01116 was negatively correlated with overall survival, whereas positively correlated with tumor size and clinical grade of osteosarcoma patients. Transfection of pcDNA-LINC01116 significantly enhanced proliferative, migratory and invasive abilities of U2OS cells, shortened G0/G1 phase period, and inhibited cell apoptosis. However, transfection of si-LINC01116 in MG63 cells obtained the opposite trends in the above-mentioned cellular behaviors. Furthermore, RIP assay confirmed the binding of enhancer of zeste homolog 2 (EZH2) to LINC01116. Knockdown of LINC01116 significantly up-regulated the expressions of phosphatase and tensin homolog deleted on chromosome ten (PTEN) and p53. Moreover, EZH2 knockdown could reverse the inhibitory effect of LINC01116 on carcinogenesis of osteosarcoma. CONCLUSIONS LINC01116 is highly expressed in osteosarcoma. Up-regulated LINC01116 can promote cell proliferation, invasion and cell cycle progression, while inhibiting the apoptosis of osteosarcoma cells. Furthermore, LINC01116 is involved in the development of osteosarcoma by binding to EZH2 to regulate expressions of PTEN and p53.

Abstract
OBJECTIVE To investigate whether Abatacept could regulate the occurrence and progression of rheumatoid arthritis (RA) by mediating cell migration of fibroblast-like synoviocytes (FLS) via mitogen-activated protein kinase (MAPK) pathway. PATIENTS AND METHODS Levels of MMP1, MMP3 and MMP13 in RA-FLS treated with Abatacept or MAPK pathway inhibitor were detected by quantitative Real-time-polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. The regulatory effect of Abatacept on MAPK pathway was detected by Western blot. Transwell assay was performed to access the role of Abatacept in regulating cell migration of RA-FLS. RESULTS Abatacept treatment remarkably downregulated levels of MMP1, MMP3 and MMP13 in FLS, which were confirmed by qRT-PCR and ELISA. Migratory ability of FLS was inhibited by Abatacept treatment. Western blot results suggested that Abatacept treatment downregulated MAPK pathway-related genes in FLS. The effects of Abatacept on MMPs expressions and cell migration were partially reversed by SB203580 treatment, the MAPK pathway inhibitor. CONCLUSIONS Abatacept inhibits FLS migration and MMPs expressions via inhibiting MAPK pathway, thereby inhibiting RA development.

Abstract
OBJECTIVE To explore the role of microRNA-9-5p in regulating osteoporosis (OS) development and its underlying mechanism. PATIENTS AND METHODS MicroRNA-9-5p expression in peripheral blood of 30 OS patients and 30 healthy subjects was examined by quantitative Real-Time-Polymerase Chain Reaction (qRT-PCR). During the processes of osteogenesis and adipogenesis, mRNA levels of microRNA-9-5p, osteogenesis-related genes, and adipogenesis-related genes in marrow stromal stem cells (MSCs) were detected by qRT-PCR as well. After overexpression or knockdown of microRNA-9-5p, the regulatory effects of microRNA-9-5p on osteogenesis-related genes and adipogenesis-related genes in MSCs were accessed by detecting their mRNA and protein levels. Alizarin red staining and oil red staining were performed to determine the osteogenic and adipogenic capacities of MSCs after microRNA-9-5p overexpression, respectively. The dual-luciferase reporter gene assay was conducted to verify the binding condition of microRNA-9-5p and Wnt3a. Finally, rescue experiments were performed to confirm whether microRNA-9-5p could regulate OS development via targeting Wnt3a. RESULTS Higher expression of microRNA-9-5p was found in OS patients than that of healthy controls. MicroRNA-9-5p expression was downregulated with the prolongation of osteogenic induction, whereas it was upregulated during the process of adipogenic differentiation. Overexpression of microRNA-9-5p downregulated mRNA levels of osteogenesis-related genes (ALP, RUNX2, and OPN), whereas upregulated adipogenesis-related genes (PPARγ, Adipsin, and C/EBPα) in MSCs. The number of calcified nodules became fewer after microRNA-9-5p overexpression in MSCs. MSCs that overexpressed microRNA-9-5p showed more lipid droplets than that of controls. Subsequently, the dual-luciferase reporter gene assay verified that Wnt3a is the target gene of microRNA-9-5p. Both mRNA and protein levels of Wnt3a were negatively regulated by microRNA-9-5p. Rescue experiments indicated that the regulatory effects of microRNA-9-5p on osteogenesis and adipogenesis of MSCs were reversed by Wnt3a overexpression. CONCLUSIONS MicroRNA-9-5p is lowly expressed in the peripheral blood of OS patients. MicroRNA-9-5p promotes the occurrence and progression of OS through inhibiting osteogenesis and promoting adipogenesis via targeting Wnt3a.

Abstract
It is currently uncertain whether people with diabetes are at higher risk of severe illness from coronavirus disease 2019 (COVID-19). We found that diabetes was associated with an approximately 4-fold increased risk of having severe/critical COVID-19 illness. This association was independent of age, sex, obesity, hypertension and smoking. These findings highlight the urgent need for a multidisciplinary team-based approach to management of this patient population.

Abstract
OBJECTIVE To investigate the expressions, biological effects and potential mechanism of miR-424 in glioma. METHODS AND METHODS A total of 54 glioma tissues and 12 normal brain tissues were collected. Human glioma cells (A172, SHG-44, T98, LN18, and LN229) and normal human astrocytes (NHAs) were cultured. Cell invasion and migration capacities were detected by transwell assay. KIF23 was predicted and confirmed as a direct target of miR-424 by TargetScan prediction and Dual-luciferase reporter assay. Six-week-old female nude mice were used for Xenograft tumor formation assay. RESULTS Results of this study demonstrated a significant decrease of miR-424 expressions both in glioma cells and tissues. Moreover, the declined miR-424 expressions were observed to be correlated with the poor OS and worse clinicopathological parameters of glioma patients. Functional assays indicated that miR-424 restoration could inhibit the glioma cell epithelial-to-mesenchymal transition (EMT) and metastasis, as well as the tumor growth rate and tumor size of glioma mice. Additionally, kinesin family member 23 (KIF23) expressions were found to be significantly enhanced in glioma specimens, and KIF23 was considered to be a functional target for miR-424 in glioma. CONCLUSIONS MiR-424, considered as a tumor-suppressor, inhibited cell metastasis and EMT by targeting KIF23 in glioma, which may provide a novel insight into tumorigenesis and the basis for the development of miRNA-targeting therapies against glioma.

Abstract
Objective: To investigate the effect of NACHT-LRR-PYD- containing proteins 3 (NLRP3) mediated pyroptosis in myocardial cells undergoing hypoxia/deoxygenation (H/R) injury. Methods: In order to observe whether H/R-treatment could cause pyroptosis, H9c2 cells were divided into 2 groups randomly using the lottery method: control group(without H/R-treatment) and H/R group (in which the H9c2 cells were underwent H/R-treatment). In order to clarify the role of pyroptosis in H/R-injury, H9c2 cells were divided into 4 groups randomly using the lottery method: control group(in which the H9c2 cells were cultivated with normal medium); YVAD group(in which the H9c2 cells were pretreated with z-Val-Ala-Asp(Ome)-fluoromethylketone (Z-YVAD-FMK) 20 μm for 4 hours, then replaced with normal medium); H/R group(H9c2 cells underwent H/R-treatment); YVAD+H/R group (in which the H9c2 cells were pretreated with 20 μm Z-YVAD-FMK for 4 hours before H/R-treatment). To determine whether H/R-induced cell pyroptosis is associated with NLRP3, H9c2 cells were divided into 4 groups randomly using the lottery method: control group (in which cells were transfected with a control nonspecific siRNA); si-NLRP3 group (in which cells were transfected with NLRP3-targeting siRNA); H/R group(in which cells were transfected with a control nonspecific siRNA before H/R-treatment); si-NLRP3+H/R group(in which the H9c2 cells were transfected with NLRP3-targeting siRNA before H/R-treatment). Pore formation on cell membrane was detected by propidium iodide (PI) staining. Cell viability was detected by CCK8 reagent. The protein expression of Caspase-1, interleukin-1β (IL-1β) and NLRP3 was detected by Western blot. Results: (1) The positive rate of PI staining ((26.46±5.15)% vs. (1.69±0.73)%,P<0.01), expression of NLRP3 (0.57±0.16 vs. 0.23±0.06,P<0.01), expression of Caspase-1 (1.07±0.13 vs. 0.37±0.08,P<0.01), and expression of IL-1β (0.38±0.08 vs. 0.16±0.05,P<0.01) were significantly higher in H/R group than in control group. (2)The cell vitality was significantly higher in YVAD+H/R group than in H/R group ((87.31±9.05)% vs. (73.30±7.19)%, P<0.05).The positive rate of PI staining was significantly decreased in YVAD+H/R group than in H/R group ((18.12±4.36)% vs. (26.45±4.60)%, P<0.05). The expression of Caspase-1 (0.72±0.12 vs. 1.07±0.15, P<0.05) and IL-1β(0.29±0.07 vs. 0.39±0.06, P<0.05) were significantly lower in YVAD+H/R group than in H/R group. (3) The cell vitality was significantly increased in si-NLRP3+H/R group than in H/R group ((85.46±7.71)% vs. (72.41±5.53)%, P<0.05). The positive rate of PI staining was significantly lower in si-NLRP3+H/R group than in H/R group ((18.22±4.20)% vs. (26.73±3.26)%, P<0.05). The expression of Caspase-1(0.87±0.07 vs. 1.15±0.15, P<0.05) and IL-1β(0.41±0.07 vs. 0.58±0.10, P<0.05) were significantly decreased in si-NLRP3+H/R group than in H/R group. Conclusion: NLRP3 mediated pyroptosis is involved in H/R injury of myocardial cells.

Abstract
Mercury emission flows in the global supply chains have evolved into an ever-increasing complex network. However, the underlying structural features remain unknown. Therefore, the global embodied mercury flow network was constructed to reveal the characteristics of energy-induced mercury emissions embodied in international trade at both national and sectoral scales. The small-world nature of the global mercury flows network was identified at both scales. Results showed that the global mercury flow network can be divided into 4 national communities, within which the spillover effects of the interventions in one region spread more easily. Detecting the mercury-intensive supply-chain clusters highlights the importance of monitoring these clusters that dominate mercury emissions in global supply chains, which could offer insights on where policy can be implemented effectively. Moreover, vital regions (e.g., mainland China, the USA, and Germany) and sectors (e.g., Petroleum, Chemical and Non-Metallic Mineral Products, Metal Products and Electrical and Machinery in mainland China) for global mercury control have been unveiled by using an integrated centrality measurement system. Our results highlight that, for the overall mercury reduction, regional and even global collaboration should be enhanced along with efforts in individual regions, and enterprises in these important sectors should invest more to green their cluster-wise supply chains.

Abstract
Objective: To preliminarily study on the possible mechanism of cerebral cortical dysfunction pattern after anterior cruciate ligament (ACL) preservation reconstruction with autologous tendon through resting-state functional magnetic resonance imaging (fMRI). Methods: From June 2015 to February 2019, 18 patients (10 males and 8 females with an average age of (36±10) years) with left anterior cruciate ligament rupture and treated with arthroscopic preservation reconstruction with autologous tendon were enrolled in this study, and 17 comparable healthy controls were included in Tongji Hospital of Tongji University. fMRI was performed after the postoperative period (2 to 12 weeks). The fMRI data were preprocessed by SPM8 software package and RESTplus software. The amplitude of low-frequency fluctuation (ALFF) and the fractional amplitude of low-frequency fluctuation (fALFF) in those two groups were calculated. Two-sample t-test was performed on ALFF and fALFF of the two groups, and multiple test corrections were performed by using AlphaSim. These methods were used for contrast studies on the characteristic activities of the brain dysfunction. Results: Compared with those in the control, ALFF in the central cingulate gyrus (cingulum_mid_bilateral), involving the auxiliary movement zone (supp_motor_ area) were significantly higher in the patients (P<0.01 before correction, P<0.05 after AlphaSim correction). The fALFF in activation cluster 1 was significantly higher in the right central gyrus (postcentral_R), the right lower lobule (parietal_inf_R), and the right upper margin (supramarginal_R) in the patients than that in the normal control group, respectively (P<0.01 before correction, P<0.05 after AlphaSim correction); the fALFF in activation cluster 2 in the right central cingulate gyrus (cingulum_mid_R), involving the right auxiliary movement zone (supp_motor_area_R) was significantly higher in the patients than that in the normal control group, respectively (P<0.01 before correction, P<0.05 after AlphaSim correction). Conclusion: The patients' cerebrum cortical function associated with the kinesthesis and their regulations are abnormally changed after anterior cruciate ligament preservation reconstruction with autologous tendon.

Abstract
The type 2 interleukin-1 receptor (IL-1R2) is one of natural IL-1β singling inhibitors in mammals. We cloned and sequenced the IL-1R2 gene in V. variegatus (VvIL-1R2). The phylogenetic analysis showed that the molecular structure VvIL-1R2 is similar to that of its orthologues in other vertebrates. The expression levels of VvIL-1R2 are relatively high in the peripheral blood leukocytes (PBLs), gill, and spleen. In addition, peculiar expression patterns for his molecule were detected at various developmental stages, implying that in flatfishes the IL-1R2 may have be important for embryonic development and metamorphosis. In PBLs, the treatment with pathogen-associated molecular patterns (PAMPs) induced a significant and rapid up-regulation of VvIL-1R2, pointing at its involvement in the immune responses against bacterial and viral pathogens.

Abstract
Objective: To discuss the efficacy and safety of subinguinal microsurgical varicocelectomy in the treatment of non-obstructive azoospermia (NOA) with varicocele. Methods: The clinical data of 141 patients with NOA and varicocele who underwent subinguinal microsurgical varicocelectomy from March 2015 to June 2017 in Shanghai General Hospital was collected.One hundred and ten patients suffered from varicocele on the left side, 1 on the right side, and the rest (30 cases) were bilateral varicocele. Grade Ⅰ varicocele were found on 7 sides (the right and left side was count respectively), grade Ⅱ on 121 sides, and grade Ⅲ on 43 sides. Sperm analysis, pregnancy rate and complications were recorded after at least 6 months since operation. Results: Eleven cases were lost during the follow-up. Eighteen of the remaining 130 NOA patients processed successful sperm retrieval in post-operative semen analysis (18/130, 13.8%). Six couples(6/130, 4.6%) succeeded in natural pregnancy. Five couples (5/130, 3.8%)underwent successful pregnancy following with intracytoplasmic sperm injection(ICSI). Twenty-six out of the remaining 112 patients underwent the micro dissection testicular sperm extraction (micro-TESE), and 4 patients got a successful sperm retrieval (4/26, 15.4%). Among them, 2 couples had successful pregnancy with ICSI. Totally 2 cases of postoperative infection of incision were found. Conclusions: Microsurgical varicocelectomy had a beneficial effect on sperm quality of patients suffered from NOA with varicocele to some extent, even leading to unassisted pregnancy or avoiding micro-TESE before ICSI. Microsurgical varicocelectomy could be applied in the treatment of NOA with varicocele.

Abstract
Objective: Data from the surveillance program was collected, to analyze the situation of hospitalization and cases of death with recorded causes, in Shenzhen, from 1995 to 2014. Situation of hospitalization and causes of deaths were studied in Shenzhen which had been a fast-developing city with growing number of immigrants so as to provide reference for decision-making on related prevention and control strategies. Methods: Data on hospitalizations and deaths collected from the surveillance program, were classified by both International Classification of Diseases (ICD)- 9 and ICD-10. A database was constructed with methods on related descriptive and trend analysis. Results: Around 6.3 million inpatients were seen in the past two decades in Shenzhen. The top five diseases for hospitalization were pregnancy childbirth and puerperium complications, respiratory diseases, injury and poisoning, digestive system diseases and circulatory system diseases, that accounting for 68.4% of all the hospitalization burden. The number of inpatients increased annually, with an 11 times increase during the past two decades. Proportions for pregnancy childbirth and puerperium complications, circulatory system diseases and urinary system diseases all showed increasing (χ(2)=53 806.94, 6 893.95 and 15 383.14, P<0.01), while proportions for injuries and poisoning, respiratory diseases, digestive system diseases showed a declining trend (χ(2)=131 480.09,1 711.84 and 11 367.66, P<0.01). Number of cumulative inpatient deaths exceeded 60 000, with the top five causes as malignant tumor, circulatory system diseases, injury and poisoning, respiratory system diseases and digestive system diseases, that accounting for 82.28% of all the inpatient deaths. Deaths due to circulatory system diseases, injury and poisoning increased and then decreased. Malignant tumor and respiratory diseases-induced deaths showed an increasing trend (χ(2)=1 546.48, 309.55, P<0.01), while induced deaths from disease of the other systems showed slight changes. The overall case fatality rate showed an annual decline (χ(2)=4 378.63, P<0.01), from 2.23% in 1995 to 0.74% in 2014, with mortality attribute to tumor, circulatory system disease decreased significantly. Conclusions: Shenzhen had been under an ageing transition, with relatively young population living in the city. Chronic diseases such as tumor gradually had become the major causes for heavy hospitalization burden on the population of Shenzhen.

Abstract
Objective: To examine the effects of ursodeoxycholic acid combined with Traditional Chinese Medicine on biochemical response in patients with primary biliary cholangitis. Methods: According to the method of receiving treatment, 197 patients with primary biliary cholangitis were divided into Traditional Chinese Medicine plus Western medicine group (93 cases, 47.2%) and Western medicine group (104 cases, 52.8%). From the baseline date, the combined group was treated with ursodeoxycholic acid plus traditional Chinese medicine decoction or Chinese patent medicine for at least one month and the Western medicine group simply took ursodeoxycholic acid . Additionally, Traditional Chinese medicine decoction prescriptions were mainly Xiaoyaosan and Yinchenhao. Chinese patent medicine were restricted to Biejia Ruangan tablets, Fuzheng Huayu capsules, Jiuweigantai capsules and Yinzhihuang capsules, which were used to treat liver fibrosis and cholestasis. The primary efficacy endpoint was defined as ALP level < 1.67 × ULN and ≥ 15% decrease in ALP with baseline level and TBIL≤ULN after 12 months of treatment. Results: The overall biochemical response rate of patients was 35.0% (69/197). The response rate of TCM+ Western medicine group was 43.0% (40/93), and that of Western medicine group was 27.9% (29/104). The difference between the two groups was statistically significant (χ(2) = 4.936, P < 0.05). Further analysis showed that the Chinese and Western medicine group was superior to the Western medicine group alone in reducing γ-glutamyltransferase (GGT) and TBiL [the median decline were GGT: 160.1 U/L and 111.3 U/L (Z = -2.474, P < 0.05), TBiL: 5.2 umol/l and 3.1 umol/l (Z = -2.125, P < 0.05)]. Conclusion: UDCA combined with TCM therapy can remarkably improve the biochemical response rate in patients with PBC and distinctly decrease the TBIL and GGT levels than UDCA monotherapy.

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

Abstract
Objective: To investigate the incidence rate of transjugular intrahepatic portosystemic shunt (TIPS) complications in the treatment of cirrhotic portal hypertension, and analyze the cause of complication to management methods. Methods: Data of 116 patients obtained from Zhongnan Hospital of Wuhan University were retrospectively analyzed. Portal venous pressure, routine blood test, coagulation test, liver and kidney function test, ammonia blood test, imaging and endoscopy reports were collected before and after procedure. The incidence rate of hepatic encephalopathy, gastrointestinal bleeding, ascites and shunt dysfunctions were observed. Data were expressed as mean ± Standard deviation and analyzed by t-test. A chi-squared test was used for comparison between categorical variables. Results: The success rate of TIPS operation was 97.41% (113/116). Two patients underwent prompt TIPS procedure due to active bleeding. Bleeding was successfully stopped. Portal venous pressure of 113 patients decreased from (42.73 ± 7.64) cmH(2)O to (24.92 ± 7.60) cmH(2)O, and the difference was statistically significant (P < 0.01). Twenty cases were of hepatic encephalopathy. Preoperative level of Child-pugh class C patients was more susceptible to hepatic encephalopathy within 3 months after procedure than class A and B. After TIPS procedure, there were 22 cases of gastrointestinal bleeding, 18 cases of shunt dysfunctions and 26 cases of disease related death. Conclusion: Rational patient selection strategies can effectively reduce portal venous pressure, incidence of hepatic encephalopathy, improve mid-and long-term therapeutic effects, and provide opportunities for liver transplantation.

Abstract
Objective: To deeply investigate the gene expression profiles of esophageal squamous cell carcinoma (ESCC) and the relationship of gene expression levels with prognosis from The Cancer Genome Atlas (TCGA) database. Methods: RNA-seq V2 data of 11 normal samples and 81 esophageal squamous cell carcinoma patients, and their corresponding clinical data were downloaded from The Cancer Genome Atlas database. Differentially expressed genes between normal and tumor samples were identified by using edgeR package. Gene function enrichment analyses of differentially expressed genes were conducted. A protein-protein interaction network based on differentially expressed genes was constructed by using STRING database and the hub genes were identified based on the created gene co-expression network. In addition, survival analysis was performed. Results: Totally, 2 788 genes were identified as differential expression. Among these, 1 168 genes were up-regulated and 1 620 genes were down-regulated in tumor cases compared with normal samples. Up-regulated genes were enriched in cell cycle, DNA replication and mismatch repair pathways, while down-regulated genes were enriched in metabolic pathways. 707 genes and their 3 428 interactions were identified by protein-protein interaction analysis. Genes with copy number amplifications were considered to interact with other crucial genes. 10 co-expression modules were identified based on the gene co-expression network analysis and the ribosomal protein genes were illustrated to be correlated with tumor locations of ESCC patients (P=0.003). The 3-years survival rates of high and low expression of TNFRSF10B groups were 82.5% and 15.1%, respectively. Similarly, the 3-years survival rates of high and low expression of DDX18 groups were 82.4% and 15.2%, respectively. The survival differences stratified by these two genes were statistically significant (both P<0.1). Conclusions: The analysis results of TCGA database showed that ribosomal protein genes are correlated with tumor locations of ESCC patients. Low expressions of TNFRSF10B and DDX18 are associated with poor prognose of ESCC patients. Consequently, TNFRSF10B and DDX18 may serve as predictive markers for ESCC patients.

Abstract
We report accurate quantum Monte Carlo calculations of nuclei up to A=16 based on local chiral two- and three-nucleon interactions up to next-to-next-to-leading order. We examine the theoretical uncertainties associated with the chiral expansion and the cutoff in the theory, as well as the associated operator choices in the three-nucleon interactions. While in light nuclei the cutoff variation and systematic uncertainties are rather small, in ^{16}O these can be significant for large coordinate-space cutoffs. Overall, we show that chiral interactions constructed to reproduce properties of very light systems and nucleon-nucleon scattering give an excellent description of binding energies, charge radii, and form factors for all these nuclei, including open-shell systems in A=6 and 12.

Abstract
Gamma radiation has been used in food processing for many years, though it has certain effects on food components. Whey protein solutions (10%/30%, wt/vol) were treated with gamma radiation at various dosages (10-25 kGy) and evaluated for microbial changes in the solutions and physicochemical and structural changes of whey proteins. Whey protein solutions after gamma radiation showed substantially lower populations of all viable microorganisms than those of controls. The 10% whey protein solution treated at radiation of 20 or 25 kGy remained sterile for up to 4 wk at room temperature. Gamma radiation increased viscosity and turbidity and decreased soluble nitrogen of whey protein solutions compared to nonradiated control samples regardless of radiation dosage. Nonreducing sodium dodecyl sulfate-PAGE suggested that whey proteins under gamma radiation treatment formed aggregates with high molecular weights. Reducing sodium dodecyl sulfate-PAGE showed that disulfide bonds played a role in gamma radiation-induced whey protein cross-linking. Scanning and transmission electron microscopy micrographs exhibited large aggregates of whey proteins after gamma radiation treatment. Results suggested that gamma radiation could be applied to whey protein solution for purposes of reducing microbial counts and cross-linking protein molecules.

Abstract
We investigate the recent Daya Bay results on the changes in the antineutrino flux and spectrum with the burnup of the reactor fuel. We find that the discrepancy between current model predictions and the Daya Bay results can be traced to the original measured ^{235}U/^{239}Pu ratio of the fission β spectra that were used as a base for the expected antineutrino fluxes. An analysis of the antineutrino spectra that is based on a summation over all fission fragment β decays, using nuclear database input, explains all of the features seen in the Daya Bay evolution data. However, this summation method still allows for an anomaly. We conclude that there is currently not enough information to use the antineutrino flux changes to rule out the possible existence of sterile neutrinos.

Abstract
High-affinity tyrosine kinase A (TrkA) is responsible for the biological activities of nerve growth factor. Most studies of the molecular mechanisms of TrkA that underlie the development of the spinal cord have been conducted in animals and the expression pattern of TrkA during the development of the human fetal spinal cord is not well characterized. We investigated 45 3-28-week-old (G3W-G28W) human fetuses. We assessed the expression pattern of TrkA in the human fetal spinal cord using immunohistochemistry, western blot and reverse transcription polymerase chain reaction to clarify the spatiotemporal developmental changes and to determine the role TrkA plays in development. TrkA immunoreactive products were detected widely in the alar and basal plates, ependyma, glial cells, gray and white matter, internal limiting membrane, mantle layer, marginal layer, neuroepithelium and neurons during this period of development. Expression levels of TrkA mRNA and protein peaked at G12W and G16W, respectively. The strong expression of TrkA was closely related to the formation of the dorsal and ventral horns, and the differentiation of somatic motor neurons during late embryonic development. Our findings suggest that TrkA receptors play crucial roles during the development of human fetal spinal cord. The characteristic expression patterns may clarify the developmental characteristics of the human spinal cord.

Abstract
Three dimensional topological insulators, as a new phase of quantum matters, are characterized by an insulating gap in the bulk and a metallic state on the surface. Particularly, most of the topological insulators have narrow band gaps, and hence have promising applications in the area of terahertz optoelectronics. In this work, we experimentally demonstrate an electronically-tunable terahertz intensity modulator based on Bi1:5Sb0:5Te1:8Se1:2 single crystal, one of the most insulating topological insulators. A relative frequency-independent modulation depth of ~62% over a wide frequency range from 0.3 to 1.4 THz has been achieved at room temperature, by applying a bias current of 100 mA. The modulation in the low current regime can be further enhanced at low temperature. We propose that the extraordinarily large modulation is a consequence of thermally-activated carrier absorption in the semiconducting bulk states. Our work provides a new application of topological insulators for terahertz technology.

Abstract
Objective: To study the value of three-dimensional(3D) visualization in the diagnosis and surgical treatment for pancreatic tumor. Methods: From June to September 2016, 26 patients with pancreatic tumors in Jinling Hospital, Medical School of Nanjing University were involved. The study included 26 patients(8 females and 18 males) with mean age of (57±12)years (ranging from 23 to 77 years). And there were 20 malignant tumors and 6 benign tumors. All of them were examined with abdominal thin slice CT scanning and the CT images were imported into 3D visualization system for 3D visualization. The main elements examined by 3D visualization included tumor shape, size, and location; distribution and morphology of the peripancreatic lymph node; the relationships among neoplasms, organs and blood vessels. Results: Among the 26 patients, there were 21 cases with pancreatic cancer, of which 15 cases successfully underwent standard pancreatectomy. All patients were operated underwent accurate assessment. The 3D model demonstrated the origination and bifurcations of blood vessels, and the relationships among neoplasms, organs and blood vessels efficiently. The 3D technique could facilitate to evaluate response of neiadjuvant chemotherapy in the pancreatic cancer patients (n=5).3D reconstruction could detect the lymph-node metastases accurately (n=12) in patients with pancreatic cancer. 3D reconstruction were applied to evaluate the the size and range of tumor on 5 cases. Conclusions: 3D reconstruction allows stereoscopic identification of the spatial relationships between physiologic and pathologic structures.The 3D technique could facilitate to evaluate distribution and morphology of the peripancreatic lymph node, and to evaluate the relationships among neoplasms, organs and blood vessels.

Abstract
Objective: To investigate the screening of serum biomarkers in patients with HBV-related acute-on-chronic liver failure (HBV-ACLF) by isobaric tags for relative and absolute quantitation (iTRAQ). Methods: Gel electrophoresis was used to isolate and remove high-abundant proteins. Each group of peptides was labeled by the iTRAQ reagents and then tested with an UltiMateTM 3000 nanoliter high-performance liquid chromatograph, and a Q-Exactive tandem mass spectrometer. The Protein Discovery software was used to analyze mass spectrometry data and perform bioinformatic analysis for differentially expressed proteins. Results: Ten samples each were included in the HBV-ACLF group and the chronic hepatitis B (CHB) group, and six samples each were included in the HBV-ACLF survival group and the HBV-ACLF death group. Compared with the CHB group, the HBV-ACLF group had 43 differentially expressed proteins, among which 34 were downregulated and 9 were upregulated. Compared with the HBV-ACLF survival group, the HBV-ACLF death group had 33 differentially expressed proteins, among which 18 were upregulated and 15 were downregulated. Conclusion: Keratin,α1-acid glycoprotein, and zinc-α2-glycoprotein identified in the serum may be used as potential biomarkers for predicting the prognosis of patients with HBV-ACLF.

Abstract
OBJECTIVE To campare the effect and tolerance beween intensified myeloablative conditioning regime (IMCR) without antithymocyte globulin (ATG) and myeloablative conditioning regime (MCR) for single-unit unrelated umbilical cord blood transplantation (sUCBT) in hematological malignancies. METHODS The clinical data of 190 patients with hematological malignancies undergoing sUCBT between April 2000 and December 2013 at Department of Hematology, Anhui Provincial Hospital were retrospectively analyzed, of whom 156 received IMCR without ATG (IMCR group), including 79 patient receiving total body irradiation (TBI)/cytosine arabinoside (Ara-C)/cyclophosphamide (CY) regime, 47 receiving fludarabine (Flu)/busulfan (Bu)/CY regime, and 30 receiving Ara-C/Bu/CY regime, and all of the 156 received a combination of cyclosporine A (CsA) and mycophelonate mofetil (MMF) for the prophylaxis of graft-versus-host disease (GVHD); the remaining 34 patients received MCR (MCR group), 30 patients receiving Bu/CY regime, and 4 receiving TBI/CY regime, all using CsA/MMF±ATG or methotrexate (MTX) for the prophylaxis of GVHD. The two groups were compared in disease status at the time of transplantation, characteristics of graft, transplantation effect, and transplantation-related complications. RESULTS There were no statistically significant differences between the two groups in gender, disease type, human leukocyte antigen match, ABO blood type match, and disease status at the time of transplantation (all P>0.05). The median age and body weight at transplantation in the IMCR group were significantly higher than those in the MCR group (13 years vs 9 years, P=0.003; 44 kg vs 26 kg, P=0.000). The median doses of infused total nucleated cells (×10(7)/kg) and CD34(+) cells (×10(5)/kg) in the IMCR group were significantly lower than in the MCR group (3.87 vs 4.99, P=0.002; 2.00 vs 3.17, P=0.000). The cumulative incidence of myeloid engraftment on the 42th day and platelet engraftment on the 120th day in the IMCR group were remarkably higher than in the MCR group [96.33%(95%CI: 96.27%-96.39%)vs 82.30%(95%CI: 80.67%-83.93%), P=0.000; 86.44%(95%CI: 86.28%-86.60%)vs 51.17%(95%CI: 49.02%-53.32%), P=0.002]. There were no statistically significant differences in the incidences of grade Ⅱ to Ⅳ acute GVHD, grade Ⅲ to Ⅳ acute GVHD, and 2-year chronic GVHD(P=0.482, 0.928, 0.579). The incidence of pre-engraftment syndrome in the IMCR group was higher than in the MCR group(82.70% vs 47.06%, P=0.000). And 180-day transplantation-related mortality (TRM) in the IMCR group was lower than that in the MCR group [20.50%(95%CI: 20.28%-20.71%)vs 42.20% (95%CI: 41.32%-45.09%), P=0.004]. Up to October 2015, with a median follow-up of 44.2(22.7-188.9)months, the estimated 3-year overall survival and disease-free survival in the IMCR group were both significantly higher than those in the MCR group (62.90% vs 34.10%, P=0.000; 58.60% vs 34.10%, P=0.001). CONCLUSION IMCR without ATG may improve the engraftment without increasing complications, reduce early transplantation-related mortality, and improve survival.

Abstract
The spotted knifejaw, Oplegnathus punctatus, is an important aquaculture fish species in China. To better understand the chromosomal microstructure and the karyotypic origin of this species, cytogenetic analysis was performed using Giemsa staining to identify metaphase chromosomes, C-banding to detect C-positive heterochromatin, silver staining to identify the nucleolus organizer regions (Ag-NORs), and fluorescence in situ hybridization (FISH) for physical mapping of the major (18S rDNA) and minor (5S rDNA) ribosomal genes. The species showed a karyotype of 2n = 48 for females, composed of 2 submetacentric and 46 telocentric chromosomes, with a fundamental number (FN) = 50, while the karyotype of males was 2n = 47, composed of 1 exclusive large metacentric, 2 submetacentric, and 44 telocentric chromosomes, with FN = 50. These karyotype results suggest that O. punctatus might have an X1X1X2X2/X1X2Y multiple sex chromosome system. C-positive heterochromatin was distributed in the centromeres of all chromosomal pairs and in the terminal portions of some chromosomes. A single pair of Ag-positive NORs was found to be localized at the terminal regions of the short arms of the subtelocentric chromosome pair, which was supported by FISH of 18S rDNA. After FISH, 5S rDNA were located on the interstitial regions of the smallest telocentric chromosome pair. This study was the first to identify the karyotype of this species and will facilitate further research on karyotype evolution in the order Perciformes.

Abstract
OBJECTIVE The purpose of the current study was to characterize the expression of long-noncoding-RNA ZFAS1 (ZFAS1) and assess the clinical significance of ZFAS1 in non-small cell lung cancer (NSCLC). PATIENTS AND METHODS A total of 173 patients with NSCLC were addressed in the present retrospective study. Expression levels of ZFAS1 were detected by quantitative real-time PCR. We further analyzed the correlation between ZFAS1 and clinicopathologic features of NSCLC with X2-test. Survival rate was determined with Kaplan-Meier and statistically analyzed with the log-rank method between groups. Univariate and multivariate analyses were performed to analyze the prognostic significance of ZFAS1 expression. RESULTS ZFAS1 was upregulated in NSCLC tissues (p < 0.01) and higher expression levels of ZFAS1 were found in more advanced tumor tissues (All p < 0.05). ZFAS1 expression levels were significantly associated with tumor differentiation grade (p = 0.028), lymph node metastasis (p = 0.001) and TMN stage (p = 0.001). Furthermore, we found that patients with higher ZFAS1 expression level are associated with a poorer overall survival. Univariate and multivariate analyses indicated that high ZFAS1 expression was an independent prognostic factor for poor survival of NSCLC patients. CONCLUSIONS Our results illustrated the potential role of ZFAS1 as a prognostic marker for NSCLC patients.

Abstract
AIMS A high-quality inoculum of Gluconacetobacter xylinus is important to produce bacterial cellulose (BC), a versatile biomaterial. This work aims to develop a method of preparing an inoculum of this bacterium with high cell density and without mutants. METHODS AND RESULTS Inocula of G. xylinus ACCC 10220 without and with cellulase or carboxymethyl cellulose (CMC) were prepared in shaken culture. BC pellets and BC-negative mutants were present in the inoculum without additives but absent in the inoculum with additives. Based on BC weights statically produced in fresh BC-producing media initiated by different seed culture, the 24-h-shaken inoculum with 1·50% (w/v) CMC was the best because of high biomass and absence of mutants. The BC weights in fresh media inoculated by the 96-h-static inoculum and 24-h-shaken CMC inoculum at 7% (v/v) were 0·70 and 1·05 g l(-1) , respectively, implying significant difference (P < 0·01) in BC weights. However, structure properties of the two BC samples, including the crystallinity index, mass fraction of cellulose Iα , degree of polymerization (DP) and micromorphology were slightly different. CONCLUSIONS The 24-h-shaken CMC inoculum was the most suitable for a starter culture of BC. SIGNIFICANCE AND IMPACT OF THE STUDY A novel method of preparing G. xylinus inoculum in shaken culture was developed, featuring high biomass, absence of mutants and no BC entanglements. Cellulase or CMC added into the medium completely suppressed mutation of G. xylinus, and CMC facilitated to form colloidal BC with the low DP in shaken culture, indicating less BC stress to cells. These findings suggested the mutation could be induced by BC stress, and not by shear stress commonly accepted.

Abstract
OBJECTIVE To analyze the characteristics of distribution and drug resistance of bacterial infection in several different parts of hematology department inpatients of Anhui Provincial Hospital from January 2010 to December 2014, including patients who had received hematopoietic stem cell transplantation (HSCT). METHODS Anti-microbial susceptibility test was done by Kirby-Bauer method and automated systems and the data were analysed by WHONET 5.6 software. RESULTS A total of 3 312 copies of inspection samples were analyzed, including 2 716 (82%) blood samples and other 596 specimens (18%). 634 bacterial strains were isolated from 3 312 samples (19.14%) including 488 samples (76.97%) from blood culture. 427 (67.35%) bacterial strains were gram-negative, and the other 207 (32.65%) were gram-positive. Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa were most common gram-negative bacterial and the resistant rates to imipenem were 0.8%, 11.8% and 3.3%, respectively. Detection rates of Extended-spectrum beta-lactamases in Escherichia coli and Klebsiella pneumoniae were 83.9% and 75.0%, respectively. At the same time, Coagulase negative Staphylococcus, Streptococcus and Enterococcus were most common kinds of gram-positive bacteria. Methicillin-resistant coagulase negative staphylococcus accounted for 65.9% antibiotic resistance. No vancomycin and/or linezolid and/or tigecycline resistant strains of Staphylococcus spp. and Enterococcus spp. were found in those patients. CONCLUSION Patients with hematology diseases had a higher risk of bacterial infections, mainly caused by Gram-negative bacteria. There are different distributions of bacterial in different wards.

Abstract
In this study, the immune response induced by a mixture of polysaccharide and nucleic acid extracted from Bacillus Calmette-Guerin (BCG) was evaluated in chickens inoculated with infectious bursal disease virus (IBDV) vaccine. After the mixture was injected intramuscularly at a dose of 0.075, 0.15 or 0.3 mg·kg(-1)·day(-1) for 3 days, the 14-day-old chickens were inoculated with the attenuated IBDV vaccine via intranasal and ocular routes. The relative weight of bursa of Fabricius (BF) and thymus, the serum IBD antibody titer, the CD4+/CD8+ ratio, and the concentrations of IFN-γ, IL-2 and IL-6 in peripheral blood were investigated on days 5, 15 and 25. The IBD antibody titer in BCG-treated groups was higher than in the negative control and only IBD-vaccinated chickens, indicating that the mixture of BCG can significantly enhance chicken humoral response. CD4+/CD8+ and the secretions of IFN-γ, IL-2 and IL-6 were also clearly increased compared with that in the negative control and IBD-vaccinated chickens, indicating that the mixture can also enhance the cell-mediated immune response. The results also showed that the relative weights of BF and thymus increased after chickens were inoculated with BCG, indicating that the BCG mixture can clearly enhance the immunity of IBD-vaccine and can be expected to be viewed as a candidate for a new type of immune adjuvant.

Abstract
We conducted a case-control study with a relatively large sample size, and investigated the association between rs2275913G>A and rs763780T>C and the risk of cervical cancer. Three hundred and six newly diagnosed patients with histologically confirmed cervical cancer and 354 cancer-free control subjects were recruited from the Forestry General Hospital between May 2011 and May 2014. The gene polymorphisms rs2275913G>A and rs763780T>C were identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. By unconditional logistic regression analysis, our study found that the AA genotype and the A allele of rs2275913 were associated with a higher risk of cervical cancer compared with the wild-type genotype, and the ORs (95%CIs) were 2.84 (1.57-5.23) and 1.55 (1.22-1.97), respectively. Compared with the G allele, the A allele of rs699947 was associated with a significantly increased risk of cervical cancer in subjects above 20 years and who were positive for human papillomavirus 16 (HPV-16) or HPV-18 infection. Patients with the A allele of rs2275913 had increased risk of cervical cancer, regardless of the number of births they had experienced or their smoking habits. We suggest that rs2275913 may play a role in the etiology of cervical cancer, although further large-sample studies are needed to confirm these observations.

Abstract
The soft scales (Hemiptera: Coccoidea: Coccidae) are a group of sap-sucking plant parasites, many of which are notorious agricultural pests. The quarantine and economic importance of soft scales necessitates rapid and reliable identification of these taxa. Nucleotide sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene (barcoding region) and 28S rDNA were generated from 340 individuals of 36 common soft scales in China. Distance-based [(best match, Automated Barcode Gap Discovery (ABGD)], tree-based (neighbor-joining, Bayesian inference), Klee diagrams, and general mixed Yule coalescent (GMYC) models were used to evaluate barcoding success rates in the data set. Best match showed that COI and 28S sequences could provide 100 and 95.52% correct identification, respectively. The average interspecific divergences were 19.81% for COI data and 20.38% for 28S data, and mean intraspecific divergences were 0.56 and 0.07%, respectively. For COI data, multiple methods (ABGD, Klee, and tree-based methods) resulted in general congruence with morphological identifications. However, GMYC analysis tended to provide more molecular operational taxonomic units (MOTUs). Twelve MOTUs derived from five morphospecies (Rhodococcus sariuoni, Pulvinaria vitis, Pulvinaria aurantii, Parasaissetia nigra, and Ceroplastes rubens) were observed using the GMYC approach. In addition, tree-based methods showed that 28S sequences could be used for species-level identification (except for Ceroplastes ceriferus - Ceroplastes pseudoceriferus), even with low genetic variation (<1%). This report demonstrates the robustness of DNA barcoding for species discrimination of soft scales with two molecular markers (COI and 28S) and provides a reliable barcode library and rapid diagnostic tool for common soft scales in China.

Abstract
Genetic mutations in microRNA gene can alter expression, which may interact to increase the risk of developing various diseases, including hepatitis B. However, published results are inconclusive or ambiguous. The aim of this review and meta-analysis is to more precisely estimate the association between polymorphisms in microRNA genes and hepatitis B risk. A digital search was performed of the MEDLINE EMBASE, CNKI, and CBM databases to identify relevant articles published up to February 18, 2014. Ten case-control studies were included, with a total of 6042 patients with hepatitis B and 6834 healthy controls. Nine single-nucleotide polymorphisms in the miRNA gene were examined, including miR-34b/c [rs4938723 (T>C)], miR-196a-2 [rs11614913 (C>T)], miR-146a [rs2910164 (G>C)], miR-499 [rs3746444 (T>C)], miR-122 [rs3783553 (ins/del)], miR-149 [rs2292832 (C>T)], miR-106b-25 [rs999885 (A>G)], miR-let-7c [rs6147150 (ins/del)], and miR-218 [rs11134527 (A>G)]. The meta-analysis results indicated that the miR-196a-2*T, miR-122*del, miR-106b-25*A, and miR-let-7c*del alleles/carriers increase the risk of hepatitis B among the Asian population. However, the miR-146a, miR- 499, miR-149, miR-218, and miR-34b/c polymorphisms may not be linked with the risk of hepatitis B. Further investigations are warranted to determine the exact associations between microRNA mutations and hepatitis B susceptibility.

Abstract
Primary graft failure (pGF) is a frequent complication following cord blood transplantation (CBT). For those patients who will not experience autologous recovery, salvage transplantation should be performed as early as possible. However, standardized treatment protocols for pGF, such as the optimal stem cell source, preparative regimen and the ideal time for salvage transplantation, have yet to be determined. Therefore, we analyzed 17 hematologic malignancy patients who received unmanipulated haploidentical peripheral blood (PB) and BM transplantation with reduced-intensity conditioning (RIC) as a salvage therapy for pGF after CBT. The median interval between the two transplantations was 38 days. The RIC regimen for salvage transplantation consisted of fludarabine, antithymocyte globulin, CY and low-dose TBI. The neutrophil and plt engraftments were achieved in 14 (82.4%) and 13 (76.4%) patients, respectively. The cumulative incidences of grades II-IV and grades III-IV aGVHD were 35.3% and 17.6%, respectively. The cumulative incidence of chronic GVHD was 29.4%. After a median follow-up of 43 months, 10 of 17 patients remained alive in CR. The cumulative incidence of TRM at 180 days was 29.4%. The probability of 3-year OS and leukemia-free survival was 57.5%. Our results show that unmanipulated haploidentical PB and BM transplantation under a RIC regimen is an effective treatment for pGF after CBT.

Abstract
In the spring of 2014, a survey of viral diseases on wheat (Triticum aestivum L.) was carried out in Hebei Province, China. The samples with virus-like symptoms of dwarfing and flag leaf yellowing were collected in Zhaoxian, Quyang, Anxin, and Luannan. To reproduce the viral symptoms and confirm whether the unknown virus was transmitted by insect vectors, the nymphs of aviruliferous planthopper (Laodelphax striatellus Fallen, Homoptera: Delphacidae) were transferred onto diseased wheat from the field for a 3-day acquisition access period and a 10-day incubation on fresh wheat seedlings, and then were exposed to 2- to 3-leaf stage wheat seedlings of wheat variety Shixin828 for a 3-day inoculation access period. The infected wheat plants developed mosaic symptoms on the young leaves at 7 days post inoculation (dpi), and followed with severe symptoms including stunting, chlorotic spots, and striation along the veins of leaves at around 14 dpi. The infection symptoms were same as in the field but distinct from wheat infected with Rice black streaked dwarf virus (RBSDV) or Northern cereal mosaic virus (NCMV). For further confirmation, total RNA was extracted from the symptomatic wheat leaves, and NCMV specific primers, NCMV-PF/NCMV-PR (5'-ATGGATAAGAAAGCAAGTGGA-3'/5'-TTAAAAGTCGGCATACGGGTC-3') and RBSDV specific primers, S10-F/S10-R (5'-TTACCCAACATCACGCAACT-3'/5'-GAGCAGGAACTTCACGACAAC-3') were used for amplification of sequences of phosphoprotein and coat protein genes, respectively. Neither RBSDV nor NCMV were present in the symptomatic tissue according to the RT-PCR assay (4). Tissues derived from symptomatic wheat leaves were fixed and embedded in Spurr's resin and used for ultra-thin sectioning and transmission electron microscopy observations, revealing large amounts of Rhabdovirus-like particles in the cytoplasm. The identified particles were about 315 to 353 × 46 to 57 nm, similar in size to Barley yellow striate mosaic virus (BYSMV), a member of the genus Cytorhabdovirus reported from Italy (2). The specific primer pair (5'-ACTAAGGGGGTACTCCGACC-3' and 5'-CTGATCTGCTTTGAGGGGCA-3') was designed based on the reported polymerase (L) gene sequence of BYSMV isolate Zanjan-1 (GenBank Accession No. FJ665628) (1), and used for the BYSMV detection by RT-PCR. A single bright band of the expected size (~500 bp) was obtained from total RNA extracted from the plants exhibiting symptoms in the greenhouse. No such band was amplified from asymptomatic plants, while 15 out of 23 field samples also produced the same 500-bp products in RT-PCR. PCR products from three virus-positive field samples were sequenced directly and the sequences were submitted to GenBank (KM052176, KM052177, and KM052178). BLAST search showed that the sequences shared 96 to 97% nucleotide identity with the polymerase L gene sequence of BYSMV isolate Zanjan-1, whereas only 73 to 75% identity with NCMV (AB030277 and GU985153) (1,3,5). To our knowledge, this is the first report of BYSMV occurrence on wheat in China. References: (1) R. Almasi et al. J. Phytopathol. 158:351, 2010. (2) A. Appiano et al. Cytol. 6:105, 1974. (3) H. C.

Abstract
This study included data from 185 consecutively treated patients, 16 years of age or older, who underwent myeloablative transplantation using unrelated umbilical cord blood (UCB) (UCB transplantation (UCBT), n=70) or HLA-identical sibling donor peripheral blood stem cells alone or combined with bone marrow (BMT/PBSCT, n=115) from October 2001 to December 2012. All patients received myeloablative regimens, cyclosporin A plus mycophenolate mofetil as prophylaxis for GVHD, and similar supportive care. Although hematopoietic recovery was significantly delayed after UCBT, the rate of neutrophil engraftment was comparable. The median follow-up was 53 months (range, 15-136 months) for BMT/peripheral blood SCT (PBSCT) recipients and 35 months (range, 10-123 months) for UCBT recipients. There were no significant differences in the cumulative incidence of grades III to IV acute GVHD, relapse rate, or 3-year probabilities of disease-free survival between patients receiving UCBT and those receiving BMT/PBSCT. However, the cumulative incidence of chronic and extensive chronic GVHD was lower in UCBT recipients. The rates of long-term survivors returning to school or work and off immunosuppressive therapy were significantly higher after UCBT, which indicated that long-term survivors who underwent UCBT had a higher quality of life.
