Abstract
Objective In this study, we aimed to evaluate the current status of the quality of life (QOL) of pediatric patients and plasma glucose concentration regulation in children with type 1 diabetes (T1DM) in the Ningxia Hui autonomous region. Methods The study involved children with T1DM admitted to the General Hospital of Ningxia Medical University between October 2011 and October 2021. The children and their parents completed general information and quality of life (QOL) questionnaires. The regulation of plasma glucose concentration was assessed based on HbA1c levels, and plasma glucose and QOL-influencing components were investigated. Results Among the 136 pediatric patients diagnosed with T1DM, the mean glycated hemoglobin (HbA1c) level was recorded at 8.7% (7.2%, 10.5%). A breakdown of the patient cohort revealed that 44 patients (32.4%) demonstrated good regulation of plasma glucose, 33 patients (24.3%) exhibited acceptable glycemic control, and 59 patients (43.3%) displayed poor regulation of plasma glucose. The control of plasma glucose in pediatric patients diagnosed with T1DM was affected by the duration of the disease, the patient's age, the frequency of daily plasma glucose measurements, the use of CGM, diabetic ketoacidosis (DKA), and the education level of the mother. The control of plasma glucose, dietary management, DKA, the ability to learn, and health education are interfering factors of quality of life in children diagnosed with T1DM. Effective control of plasma glucose may ensure the QOL in children with T1DM, and DKA was the risk factor for QOL. Conclusion In Ningxia, the regulation of plasma glucose in pediatric and adolescent patients with T1DM remains suboptimal, leading to poor QOL. There is a pressing need to enhance glucose regulation and QOL through comprehensive strategies, which include reinforced dietary management, rigorous monitoring of plasma glucose levels, and heightened health education levels.

Abstract
Tumor cells are usually considered defective in mitochondrial respiration, but human non-small cell lung cancer (NSCLC) tumor tissues are shown to have enhanced glucose oxidation relative to adjacent benign lung. Here, we reported that oncoprotein cancerous inhibitor of protein phosphatase 2A (CIP2A) inhibited glycolysis and promoted oxidative metabolism in NSCLC cells. CIP2A bound to pyruvate kinase M2 (PKM2) and induced the formation of PKM2 tetramer, with serine 287 as a novel phosphorylation site essential for PKM2 dimer-tetramer switching. CIP2A redirected PKM2 to mitochondrion, leading to upregulation of Bcl2 via phosphorylating Bcl2 at threonine 69. Clinically, CIP2A level in tumor tissues was positively correlated with the level of phosphorylated PKM2 S287. CIP2A-targeting compounds synergized with glycolysis inhibitor in suppressing cell proliferation in vitro and in vivo. These results indicated that CIP2A facilitates oxidative phosphorylation by promoting tetrameric PKM2 formation, and targeting CIP2A and glycolysis exhibits therapeutic potentials in NSCLC.

Abstract
Covalent organic framework (COF) membranes featuring uniform topological structures and devisable functions, show huge potential in water purification and molecular separation. Nevertheless, the inability of uniform COF membranes to be produced on an industrial scale and their nonenvironmentally friendly fabrication method are the bottleneck preventing their industrial applications. Herein, we report a new green and industrially adaptable scraping-assisted interfacial polymerization (SAIP) technique to fabricate scalable and uniform TpPa COF membranes. The process used non-toxic and low-volatility ionic liquids (ILs) as organic phase instead of conventional organic solvents for interfacial synthesis of TpPa COF layer on a support membrane, which can simultaneously achieve the purposes of (i) improving the greenness of membrane-forming process and (ii) fabricating a robust membrane that can function beyond the conventional membranes. This approach yields a large-area, continuous COF membrane (19×25 cm2 ) with a thickness of 78 nm within a brief period of 2 minutes. The resulting membrane exhibited an unprecedented combination of high permeance (48.09 L m-2 h-1 bar-1 ) and antibiotic desalination efficiency (e.g., NaCl/adriamycin separation factor of 41.8), which is superior to the commercial benchmarking membranes.

Abstract
The integrity of the blood-brain barrier (BBB) is mainly maintained by endothelial cells and basement membrane and could be regulated by pericytes, neurons, and glial cells including astrocytes, microglia, oligodendrocytes (OLs), and oligodendrocyte progenitor cells (OPCs). BBB damage is the main pathological basis of hemorrhage transformation (HT) and vasogenic edema after stroke. In addition, BBB damage-induced HT and vasogenic edema will aggravate the secondary brain tissue damage. Of note, after reperfusion, oxidative stress-initiated cascade plays a critical role in the BBB damage after acute ischemic stroke (AIS). Although endothelial cells are the target of oxidative stress, the role of glial cell-derived oxidative stress in BBB damage after AIS also should receive more attention. In the current review, we first introduce the physiology and pathophysiology of the BBB, then we summarize the possible mechanisms related to BBB damage after AIS. We aim to characterize the role of glial cell-derived oxidative stress in BBB damage after AIS and discuss the role of oxidative stress in astrocytes, microglia cells and oligodendrocytes in after AIS, respectively.

Abstract
CACNA1E is a gene encoding the ion-conducting α1 subunit of R-type voltage-dependent calcium channels, whose roles in tumorigenesis remain to be determined. We previously showed that CACNA1E was significantly mutated in patients with non-small cell lung cancer (NSCLC) who were long-term exposed to household air pollution, with a mutation rate of 19% (15 of 79 cases). Here we showed that CACNA1E was also mutated in 207 (12.8%) of the 1616 patients with NSCLC in The Cancer Genome Atlas (TCGA) datasets. At mRNA and protein levels, CACNA1E was elevated in tumor tissues compared to counterpart non-tumoral lung tissues in NSCLCs of the public datasets and our settings, and its expression level was inversely associated with clinical outcome of the patients. Overexpression of wild type (WT) or A275S or R249G mutant CACNA1E transcripts promoted NSCLC cell proliferation with activation of epidermal growth factor receptor (EGFR) signaling pathway, whereas knockdown of this gene exerted inhibitory effects on NSCLC cells in vitro and in vivo. CACNA1E increased current density and Ca2+ entrance, whereas calcium channel blockers inhibited NSCLC cell proliferation. These data indicate that CACNA1E is required for NSCLC cell proliferation, and blockade of this oncoprotein may have therapeutic potentials for this deadly disease.

Abstract
PURPOSE Post-stroke depression (PSD) is the most common psychiatric sequelae of stroke. Numerous studies revealed that event-related potentials (ERP) can reflect depression severity to a certain extent, while there is almost no research on depression after hemorrhagic stroke. Therefore, we employed a prospective cross-sectional study to explore the relationship between ERP and depression after hemorrhagic stroke. METHODS A total of 74 patients with intracranial hemorrhage were included in this study. Neurological deficits were evaluated using the National Institutes of Health Stroke Scale (NIHSS) on admission. Depression severity and cognitive impairment were measured using the 17-item Hamilton Depression Scale (HAMD-17) and the Chinese version of the Montreal Cognitive Assessment (MoCA) after two weeks of treatment. All patients were conducted auditory Oddball paradigm for event-related potential mismatch negativity (MMN) and P300. RESULTS In total, 36 patients were diagnosed with PSD at the two weeks of treatment, for a percentage of 48.6%. Depression severity of ICH patients correlated positively with both the latency of MMN (r = 0.376, P = 0.001) and P300 (r = 0.325, P = 0.005), and correlated negatively with both the amplitude of MMN (r=-0.385, P = 0.001) and P300 (r=-0.311, P = 0.007). Depression severity was negatively correlated with cognitive function after hemorrhagic stroke (r=-0.347, P = 0.002). CONCLUSION The latency and amplitude of MMN and P300 can well reflect the degree of depression after hemorrhagic stroke, which may help in the early diagnosis and effective treatment of PSD.

Abstract
Background: 5-Methylcytidine (m5C) is the most common RNA modification and plays an important role in multiple tumors including cervical cancer (CC). We aimed to develop a novel gene signature by identifying m5C modification subtypes of CC to better predict the prognosis of patients. Methods: We obtained the expression of 13 m5C regulatory factors from The Cancer Genome Atlas (TCGA all set, 257 patients) to determine m5C modification subtypes by the “nonnegative matrix factorization” (NMF). Then the “limma” package was used to identify differentially expressed genes (DEGs) between different subtypes. According to these DEGs, we performed Cox regression and Kaplan-Meier (KM) survival analysis to establish a novel gene signature in TCGA training set (128 patients). We also verified the risk prediction effect of gene signature in TCGA test set (129 patients), TCGA all set (257 patients) and GSE44001 (300 patients). Furthermore, a nomogram including this gene signature and clinicopathological parameters was established to predict the individual survival rate. Finally, the expression and function of these signature genes were explored by qRT-PCR, immunohistochemistry (IHC) and proliferation, colony formation, migration and invasion assays. Results: Based on consistent clustering of 13 m5C-modified genes, CC was divided into two subtypes (C1 and C2) and the C1 subtype had a worse prognosis. The 4-gene signature comprising FNDC3A, VEGFA, OPN3 and CPE was constructed. In TCGA training set and three validation sets, we found the prognosis of patients in the low-risk group was much better than that in the high-risk group. A nomogram incorporating the gene signature and T stage was constructed, and the calibration plot suggested that it could accurately predict the survival rate. The expression levels of FNDC3A, VEGFA, OPN3 and CPE were all high in cervical cancer tissues. Downregulation of FNDC3A, VEGFA or CPE expression suppressed the proliferation, migration and invasion of SiHa cells. Conclusions: Two m5C modification subtypes of CC were identified and then a 4-gene signature was established, which provide new feasible methods for clinical risk assessment and targeted therapies for CC.

Abstract
Graphene quantum dots (GQDs), a new quasi-zero-dimensional nanomaterial, have the advantages of a smaller transverse size, better biocompatibility, and lower toxicity. They have potential applications in biosensors, drug delivery, and biological imaging. Therefore, it is particularly important to understand the transport mechanism of the GQDs on the cell membrane. In particular, the effect of the GQD shapes on the translocation mechanism should be well understood. In this study, the permeation process of the GQDs with different shapes through a 1-palmitoyl-2-oleoylphosphatidylcholine membrane was studied using molecular dynamics. The results show that all small-sized GQDs with different shapes translocated through the lipid membrane at a nanosecond timescale. The GQDs tend to remain on the surface of the cell membrane; then, the corners of the GQDs spontaneously enter the cell membrane; and, finally, the entire GQDs enter the cell membrane and tend to stabilize in the middle of the cell membrane. Moreover, the GQDs do not induce notable damage to the cell membrane, indicating that they are less toxic to cells and can be used as a potential biomedical material.

Abstract
Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) with unknown origin spread rapidly to 222 countries, areas or territories. To investigate the genomic evolution and variation in the early phase of COVID-19 pandemic in Guangdong, 60 specimens of SARS-CoV-2 were used to perform whole genome sequencing, and genomics, amino acid variation and Spike protein structure modeling analyses. Phylogenetic analysis suggested that the early variation in the SARS-CoV-2 genome was still intra-species, with no evolution to other coronaviruses. There were one to seven nucleotide variations (SNVs) in each genome and all SNVs were distributed in various fragments of the genome. The Spike protein bound with human receptor, an amino acid salt bridge and a potential furin cleavage site were found in the SARS-CoV-2 using molecular modeling. Our study clarified the characteristics of SARS-CoV-2 genomic evolution, variation and Spike protein structure in the early phase of local cases in Guangdong, which provided reference for generating prevention and control strategies and tracing the source of new outbreaks.

Abstract
Objective: To investigate the clinicopathologic features, treatment, and prognosis in patients with Castleman disease (CD) . Methods: We retrospectively analyzed the clinicopathologic data of 59 patients for whom a diagnosis of Castleman disease was confirmed using pathological examination from October 2011 to October 2019 at the Henan Cancer Hospital. The patients were divided into the following two groups as per the following clinical classifications: unicentric CD (UCD, n=47) and multicentric CD (MCD, n=12) . Data on clinical manifestations, laboratory findings, treatment, and prognosis were analyzed. Results: There was no significant difference in the median age and the ratio of male to female between the UCD and MCD. UCD was characterized by asymptomatic enlargement of the single lymph node. The main pathological type was hyaline vascular histopathology (83.0%) . Of these, 44 patients chose surgical resection, and their prognosis was good. Treatment. MCD was characterized by multiple enlarged superficial and/or deep lymph nodes with B symptoms, weakness, and hepatosplenomegaly. Anemia, hypoproteinemia, and globulin level were increased on laboratory examinations. Plasmacyte histopathology was the main pathological type and was present in about 50.0% of the subjects. Only chemotherapy was performed for these MCD patients, followed by chemotherapy or chemotherapy followed by radiotherapy, and the efficient was 58.3% (7/12) . Conclusions: UCD, characterized by asymptomatic enlargement of the single lymph node, shows good postoperative prognosis. MCD has relatively complex clinical manifestations and poor prognosis, and optimal treatment is yet to be established.

Abstract
Objective: To understand the genetic variation and epidemiological characteristics of human respiratory syncytial virus (HRSV) in Guangzhou. Methods: Nasopharyngeal swabs specimens were collected from 0-6 year old children hospitalized with acute respiratory infection, then HRSV was tested and genotyped by RT-PCR. Phylogenetic tree was bulit using MEGA 6.0 software. NetNGlyc 1.0 server was used to predict the potential N-linked glycosylation sites. Results: A total of 1 225 nasopharyngeal specimens were collected, including 783 males and 442 females. The median (P(25), P(75)) age was 8 (3, 24) months. Among the 209 HRSV-positive cases (17.06%), 117 cases (55.98%) were HRSV-A and 92 cases (44.02%) were HRSV-B. The two distinct subgroups (HRSV-A and HRSV-B) alternately played dominant role to cause HRSV infection and exchange almost once every two years. The HRSV prevalence rate decreased with age. The HRSV-positive rate among children under 2 years old was 18.83% (196 cases), accounting for 93.78% of the total positive cases. There were 32 HRSV positive cases co-infected with at least one respiratory virus, with the co-infection rate of 15.31%. Phylogenetic tree analysis of the second hypervariable region (HVR2) of the G protein classified the HRSV-A specimens into ON1 (n=62) and NA1 (n=2) genotypes while all HRSV-B specimens belonged to BA genotype (n=53). The HVR2 of the G protein varied in using stop condon, amino acid substitutions, glycosylation sites. Conclusion: Children under 2 years old were the high risk population of HRSV infection in Guangzhou. ON1 genotype turned into a primary genetype of the HRSV-A subgroup while BA genotype dominated the HRSV-B subgroup. A greater diversification of amino acid substitutions, and some deletion and insertion of glycosylation sites embodied the polymorphism of G protein as main protective antigen.

Abstract
OBJECTIVE To compare the clinical features and follow-up results of systemic lupus erythematosus (SLE) between boys and girls. METHODS A retrospective analysis was performed for the clinical data of 79 children (18 boys and 61 girls), aged ≤14 years, who were diagnosed with SLE from 2008 to 2018. The boys and the girls were compared in terms of initial and major clinical symptoms, injury of organs/systems, related laboratory markers, and follow-up results. RESULTS As for the initial and non-initial symptoms, fever had the highest incidence rate in the boys, while facial erythema had the highest incidence rate in the girls. The boys tended to develop renal injury and hematological damage (P<0.05), with a significantly higher incidence rate of proteinuria than the girls (P<0.05), while the girls tended to develop joint pain (P<0.05). There were high abnormal rates (>80%) of anti-nuclear antibody, dsDNA, complement C3, and erythrocyte sedimentation rate in both boys and girls (P>0.05). The boys had a significantly higher disease activity than the girls at the first visit and in year 9 of follow-up (P<0.05). A one-month to ten-year follow-up showed that among the boys, 3 were lost to follow-up, 1 died, 7 were well controlled but required oral administration of large doses of hormones or immunosuppression, 2 progressed to chronic renal failure, and 1 developed lupus encephalopathy. Among the girls, 3 were lost to follow-up; 5 died; 34 were well controlled, among whom 5 were maintained on oral prednisone acetate with a dose of <10 mg, 1 was withdrawn from the drug for 1 year, and 2 were withdrawn from the drug for 2 years; 4 developed lupus encephalopathy; 1 developed depression and anxiety and had suicidal tendency in the 7th year after disease onset; 2 experienced impaired vision, blurred vision, and chloropsia; 1 developed a vascular necrosis of both femoral heads in the 3rd year of hormone administration. CONCLUSIONS There are differences in clinical features, several laboratory markers, and prognosis between boys and girls with SLE. Boys tend to have a high severity at disease onset, develop renal injury and hematological damage, and have poor long-term prognosis, while girls tend to have joint involvement.

Abstract
Purpose This study aimed to investigate the potential systemic antitumor effects of stereotactic ablative radiotherapy (SABR) and apatinib (a novel vascular endothelial growth factor receptor 2 inhibitor) via reversing the immunosuppressive tumor microenvironment for lung carcinoma. Materials and Methods Lewis lung cancer cells were injected into C57BL/6 mice in the left hindlimb (primary tumor; irradiated) and in the right flank (secondary tumor; nonirradiated). When both tumors grew to the touchable size, mice were randomly divided into eight treatment groups. These groups received normal saline or three distinct doses of apatinib (50 mg/kg, 150 mg/kg, and 200 mg/kg) daily for 7 days, in combination with a single dose of 15 Gy radiotherapy or not to the primary tumor. The further tumor growth/regression of mice were followed and observed. Results For the single 15 Gy modality, tumor growth delay could only be observed at the primary tumor. When combining SABR and apatinib 200 mg/kg, significant retardation of both primary and secondary tumor growth could be observed, indicated an abscopal effect was induced. Mechanism analysis suggested that programmed death-ligand 1 expression increased with SABR was counteract by additional apatinib therapy. Furthermore, when apatinib was combined with SABR, the composition of immune cells could be changed. More importantly, this two-pronged approach evoked tumor antigen–specific immune responses and the mice were resistant to another tumor rechallenge, finally, long-term survival was improved. Conclusion Our results suggested that the tumor microenvironment could be managed with apatinib, which was effective in eliciting an abscopal effect induced by SABR.

Abstract
The first-line treatment for metastatic esophageal squamous cell cancer (ESCC) is a platinum- or fluorouracil-based agent, followed by later treatment with taxanes or irinotecan. However, there is still no standard third-line treatment for patients with metastatic ESCC. We present a 62-year-old man initially diagnosed with locally advanced ESCC. After esophagectomy, the patient was administrated with six cycles of docetaxel and cisplatin combined with radiotherapy. After 8.0 months, computed tomography showed the left cervical lymph node metastasis. However, the metastatic lymph node was not significantly shrunk after locally palliative radiotherapy and the patient was intolerant of irinotecan as second-line systemic therapy. Then, the patient was rechallenged with six cycles of docetaxel combined with apatinib (an oral tyrosine kinase inhibitor to vascular endothelial growth factor receptor 2 [VEGFR2]), followed by single dose of apatinib as maintenance therapy. According to the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 standard, partial response was achieved in this case after treating with docetaxel combined with apatinib. Now, the progression-free survival of this patient has been 7.5 months. After administrating with apatinib for 2 weeks, hypertension (grade III) was observed. Thus, the dose of apatinib was decreased from 850 to 500 mg and then the adverse effects were controllable and tolerable. In conclusion, apatinib with concurrent docetaxel provided potential efficacy as a salvage treatment for patients with metastatic ESCC. To our knowledge, this is the first case of ESCC who responded to apatinib combined with docetaxel.

Abstract
To explore the efficacy and influencing factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with myeloid leukemia and granulocytic sarcoma (GS). Clinical outcome including hematopoietic reconstitution, transplant-related complications, survival and relapse were collected and retrospectively analyzed in 9 patients with myeloid leukemia and GS after allo-HSCT. Hematopoiesis reconstitution was achieved in all the 9 recipients. Four cases developed acute graft-versus-host disease (GVHD), and 1 with chronic GVHD. The median follow-up time after transplantation was 10(4-81) months. Only 2 cases survived, the other 7 died of relapse. The median time of relapse after transplantation was 5(3-19) months. Allo-HSCT is relatively effective treatment for patients with myeloid leukemia and GS. Relapse after transplantation remains the major factor of mortality.

Abstract
Objective: To investigate the significance of circulating tumor cells (CTC) in squamous cell carcinoma of the head and neck (HNSCC). Methods: Twenty-four patients with HNSCC treated between October 2016 and July 2017 in our department were selected (experimental group), including 23 males and 1 females, aged 47-81 years. There were 14 cases of squamous cell carcinoma of larynx and 10 cases of hypopharynx, including I-Ⅱ stage (5 cases) and Ⅲ- Ⅳ stage (19 cases). All patients were primary and/or relapsed after treatment. Nine healthy volunteers were selected as control group. A novel in vivo capture technique (CellCellector system) was used to detect CTC. SPSS23.0 was used for statistical analysis. Results: The total capture rate of CTC in patients with HNSCC before treatment was 70.8% (17/24), with 40% (2/5) for patients at I-Ⅱ stage, and 78.9% (15/19) for patients at Ⅲ- Ⅳ stage, and was 0 in patients of control group. The total capture rate of CTC in patients with HNSCC after treatment was 50% (8/16). There was no significant correlation between CTC and age, sex, location of tumor or lymph node metastasis (P>0.05). CTC was related to tumor staging and tumor differentiation (P<0.05). The positive rate of EGFRVⅢ in CTC was 26.3% (5/19). Conclusions: The CellCollector system is a very efficient way of detecting CTC, and CTC plays an important role in the occurrence, progression and metastasis of HNSCC.

Abstract
BACKGROUND Human adenovirus type 55 is a re-emerging human respiratory pathogen that is associated with several respiratory infections outbreaks in military and school populations. In this study, we describe the first HAdV55-associated hospital outbreak documented in Guangdong, China. METHODS Active surveillance was conducted in the involved neurosurgical inpatient department. All staff and patients in the involved neurosurgical department were surveyed for any symptoms of fever (≥38°C) and enlarged tonsils during the outbreak period. Throat swabs and demographic information were collected for all cases. For each specimen, assays for common respiratory viruses were performed using one-step reverse transcription-polymerase chain reaction. HAdV-positive samples were inoculated onto Hep-2 cells for isolation. Hexon genes, fiber genes, penton genes, and whole genomes were sequenced. A phylogenetic tree was constructed. RESULTS AND CONCLUSIONS Forty-three cases, including 24 laboratory-confirmed cases and 19 possible cases, were identified. Nurses had the highest attack rate of infection, with a rate of 36.4%. The attack rate for doctors and inpatients was 20.0% and 16.7%, respectively. HAdV55 was the sole pathogen identified during this outbreak. The hexon, fiber, and penton genes from seven isolated HAdV55 stains were sequenced. All these genes showed 100% homology and fell into the HAdV55 [P14H11F14] cluster, indicating that HAdV55 was the single viral strain for the outbreak. While not conclusive, the epidemic investigation revealed that the outbreak was introduced by nurses from sources outside the hospital. It was likely that a transmission from staff to inpatients had occurred.

Abstract
OBJECTIVES To establish an automation system for detection of alcohol content in blood. METHODS The determination was performed by automated workstation of extraction-headspace gas chromatography (HS-GC). The blood collection with negative pressure, sealing time of headspace bottle and sample needle were checked and optimized in the abstraction of automation system. The automatic sampling was compared with the manual sampling. RESULTS The quantitative data obtained by the automated workstation of extraction-HS-GC for alcohol was stable. The relative differences of two parallel samples were less than 5%. The automated extraction was superior to the manual extraction. A good linear relationship was obtained at the alcohol concentration range of 0.1-3.0 mg/mL (r≥0.999) with good repeatability. CONCLUSIONS The method is simple and quick, with more standard experiment process and accurate experimental data. It eliminates the error from the experimenter and has good repeatability, which can be applied to the qualitative and quantitative detections of alcohol in blood.

Abstract
Objective: To evaluate the efficacy of unrelated donor allogeneic hematopoietic stem cell transplantation(URD allo-HSCT) for children and adolescents with severe aplastic anemia (SAA). Methods: Clinical data of 34 SAA children and adolescents undergoing allo-HSCT were retrospectively analyzed from October 2001 to October 2015. According to the source of donor, the patients were divided into matched sibling donor allo-HSCT group (MSD group) and unrelated donor group (URD group). The clinical outcome of SAA children and adolescents receiving URD allo-HSCT was assessed, and patients in MSD allo-HSCT group were enrolled as control at the same period. Results: The rate of hematopoietic reconstitution, the time of neutrophil and platelet engraftment, incidence of chimerism and graft rejection between two groups were not statistically different.The incidence of acute graft-versus-host disease (GVHD) in URD group was significantly higher than that in MSD group [42.9%(6/14) vs 10.5%(2/19), P=0.047]. The incidence of grade Ⅱ-Ⅳ acute GVHD and chronic GVHD in URD were higher than those in MSD group [21.4%(3/14) vs 5.3%(1/19), P=0.288; 35.7%(5/14) vs 5.3%(1/19), P=0.062, respectively], yet without significant difference between two groups. Other transplant-related complications including pulmonary complications, hemorrhagic cystitis, incidence of EBV and CMV reactivation and venous occlusive disease were comparable with two regimens. Estimated 5-years overall survival (OS) rate and disease free survival (DFS) rate were not statistically significant between URD group and MSD group [(84.4±6.6)% vs (89.4±7.1)%, (82.5±5.4)% vs (82.1±4.3)%; P=0.766, P=0.884, respectively]. Conclusions: By multivariate analysis, the outcome of URD allo-HSCT in SAA children and adolescent is similar to MSD allo-HSCT. It could be an alternative option as the first-line treatment for SAA children and adolescents without HLA matched sibling donors.

Abstract
Up to now, over 1,000 experimental treatments found in cells and rodents have been difficult to translate to human ischemic stroke. Since ischemia and reperfusion, two separate stages of ischemic stroke, have different pathophysiological mechanisms leading to brain injury, a combination of protective agents targeting ischemia and reperfusion respectively may obtain substantially better results than a single agent. Normobaric hyperoxia (NBO) has been shown to exhibit neuro- and vaso-protective effects by improving tissue oxygenation when it is given during ischemia, however the effect of NBO would diminish when the duration of ischemia and reperfusion was extended. Therefore, during reperfusion drug treatment targeting inflammation, oxidative stress and free radical scavenger would be a useful adjuvant to extend the therapeutic window of tissue plasminogen activator, the only United States Food and Drug Administration (FDA) approved treatment for acute ischemic stroke. In this review, we discussed the neuro- and vaso-protective effects of NBO and recent finding of combining NBO with other drugs.

Abstract
The contribution of polluted dust transported from local and distal sources remains poorly constrained due to their similar geophysical and geochemical properties. We sampled aerosols in three cities in northern China (Xi'an, Beijing, Xifeng) during the spring of 2009 to determine dust flux, magnetic susceptibility and elemental concentrations. Combining dust fluxes with wind speed and regional visibility records enabled to differentiate between dust transported from long range and derived from local sources, while the combination of magnetic susceptibility and enrichment factors (EF) of heavy metals (Pb, Zn) allowed to distinguish natural aerosols from polluted ones. Our results indicate that polluted dust from long-range transport became a major end member of urban dust aerosols. Human settlements as its potential sources were confirmed by a pollutant enriched regional dust event originating from populated areas to the south as inferred by back trajectory modeling, implying their non-point source nature of dust pollution.

Abstract
Background Synanthropic rats and mice share the same environment with humans and play an important role in epidemiology of toxoplasmosis; however, there is limited information about prevalence and genetic characterization of Toxoplasma gondii in synanthropic rats and mice in China. Findings In the present study, the prevalence and genetic characterization of T. gondii naturally infected synanthropic rodents (Rattus norvegicus and Mus musculus) were investigated in the urban area of Xuzhou city, Eastern China between June 2013 and August 2014. DNA from the brain of each animal was prepared and screened by specific PCR assay targeting 35-fold repeated B1 gene (B1-PCR). PCR positive DNA samples were further genotyped by multi-locus PCR-RFLP. Overall, out of 123 synanthropic rodents, 29 samples were positive by B1 gene-targeted PCR (23.6%). Of these, 7 out of 31 (22.3%) M. musculus were positive, whereas the positive rate of R. norvegicus was 23.9% (22/92). Multi-locus PCR-RFLP analysis reveals that seven PCR-positive samples were completely genotyped and they were identified as type China 1 (ToxoDB# 9). Conclusion To our knowledge, this is the first report of molecular detection and genetic characterization of T. gondii infection in synanthropic rodents in Eastern China. The results of the present study showed a high infection pressure of T. gondii exists in the environment and synanthropic rodents infected by T. gondii may be an important source of infection for cats and other animals.

Abstract
According to pathogenic surveillance data during the first half of 2012, the H3N2 influenza virus was prevalent in Guangdong, China, but no pandemic H1N1 (pH1N1) virus was detected. This study aimed to measure the seroprevalence of pH1N1 and H3N2 infection following the influenza epidemic in 2012. We collected serum samples by stratified random sampling in a cross-sectional survey from August, 2012 to October, 2012. Antibody titers against H3N2, pH1N1, and influenza B antigens were measured by the hemagglutination inhibition (HI) assay, and age-specific seroprevalence and non-immunity were calculated. A total of 566 serum samples were collected from subjects who had not received an influenza vaccination. The seroprevalence of H3N2, pH1N1, and influenza B were 61.7%, 31.3%, and 40.4%, respectively, while non-immunity was calculated to be 9.2%, 40.6%, and 27.0%, respectively. The highest recorded seroprevalence was 86.0% for H3N2 in the 6-15 year age group, while the lowest was 14.6% for pH1N1 in the 60+ age group. Non-immunity fractions were 44.4% and 53.5% in the 0-6 and 60+ age groups, respectively. In conclusion, the seroprevalence of pH1N1 remained below 50% in all age groups following the 2012 influenza season. These data suggest that vaccination against pH1N1 antigens should be conducted, especially in the older age groups, before the next influenza season.

Abstract
Applications of graphene sheets in the fields of biosensors and biomedical devices are limited by their insolubility in water. Consequently, understanding the dispersion mechanism of graphene in water and exploring an effective way to prepare stable dispersions of graphene sheets in water is of vital importance for their application in biomaterials, biosensors, biomedical devices, and drug delivery. Herein, a method for stable dispersion of graphene sheets in water by single-stranded oligodeoxynucleotides (ssODNs) is studied. Owing to van der Waals interactions between graphene sheets, they undergo layer-to-layer (LtL) aggregation in water. Molecular dynamics simulations show that, by disrupting van der Waals interaction of graphene sheets with ssODNs, LtL aggregation of graphene sheets is prevented, and water molecules can be distributed stably between graphene sheets. Thus, graphene sheets are dispersed stably in water in the presence of ssODNs. The effects of size and molarity of ssODNs and noncovalent modification of graphene sheets are also discussed.

Abstract
The molecular characterization and phylogenetic analysis of hemagglutinin (HA) genes of human influenza H3N2 viruses in Guangdong, China from 2007 to 2010 were studied in this study. By space-time sampling of strains, the HA genes of H3N2 strains from Guangdong were sequenced and searched from Internet, and then the variation and evolution of HA genes were conducted by Lasergene 7.1 and Mega 5.05 and evolutionary rates were analyzed by epidemiological data. The phylogenetic tree was established by alignment of 17 Guangdong strains and 26 global reference strains. Ks rates and Ka rates of HA genes were 2.06 x 10(-3)-2.23 x 10(-3) Nt/Year and 1.05 x 10(-3)-1.21 x 10(3) Nt/Year during 2007-2010, while the velocity of HA1 evolution of Ka was 3. 13 times than that of HA2 evolution. Compared with HA of vaccine strain A/Perth/16/2009, the genetic homologies of Guangdong strains in 2009 reached to 98.8%-99.7% and of Guangdong strains in 2010 reached to 98.0%-98.4%. There were some amino acid substitutions in five epitope regions of HA1 during 2007-2010, especially in B region (N160K) and D region (K174R/N); the K189E/N/Q and T228A in RBS (receptor-binding site) occurred in 2010 as two glycoproteins sites substituted impacted on the HA1 antigenicity. The antigenicity of epidemic H3N2 strains in 2010 was to some degree different that of the vaccine strain A/ Perth/16/2009. According to that there were variations of B and D epitopes and two sites of RBS and two glycoprotein in Guangdong H3N2 HA1 genes, WHO/ CDC should recommend new representative strains during 2011-2012 influenza seasons if H3N2 HA genes further evolve in the near future.

Abstract
BACKGROUND/AIMS To evaluate clinical significance of portal hemodynamic investigation in prediction of hepatic functional reserve in patients with hepatocellular carcinoma undergoing operative treatment. METHODOLOGY By using the color Doppler velocity profile technique, preoperative portal hemodynamic status was assessed in 29 patients with hepatocellular carcinoma treated surgically, including 15 segmentectomies, 6 hemihepatectomies and 8 transarterial chemoembolizations. Forty-six normal volunteers were taken as control. Comparison of preoperative portal hemodynamics between patients recovering from operation smoothly (tolerant subgroup) and those with major complications or death (intolerant subgroup) was done, and discriminant analysis was employed to identify the cut-off value for significant parameters that maximally separate the tolerant subgroup from the intolerant subgroup. RESULTS In the portal trunk, CSVmax (maximum cross-sectional mean velocity) was significantly lower in the hepatocellular carcinoma group compared with the normal group (P < 0.01); flow volume was not obviously different between the two groups; congestion index was markedly higher in the hepatocellular carcinoma group than that of the normal group (P < 0.05). In the splenic vein, CSVmax and congestion index was not obviously different between the hepatocellular carcinoma and the normal groups; flow volume was significantly higher in the hepatocellular carcinoma group than that of the normal group (P < 0.05). In the hepatocellular carcinomas, twenty-three patients recovered smoothly from the operation and the remaining 6 had severe complications or death. Tolerant subgroup had a significantly higher preoperative CSVmax and flow volume and lower congestion index of the portal trunk compared with the intolerant subgroup (all P < 0.01). Discriminant analysis revealed that portal trunk CSVmax > 13.50 cm/s and flow volume > 12.13 mL/min/kg could predict tolerance for surgery, with an accuracy of 82.7% and 89.7%, respectively. CONCLUSIONS The results suggest that preoperative portal hemodynamic status in hepatocellular carcinomas had a close correlation with hepatic functional reserve, and CSVmax and flow volume of portal trunk might become valuable predictive parameters.

Abstract
PURPOSE To evaluate the use of percutaneous microwave coagulation therapy for hepatocellular carcinoma, particularly with tumor nodules larger than 2 cm in diameter. MATERIALS AND METHODS Fifty patients with 107 hepatocellular carcinoma nodules (mean diameter, 2.7 cm +/- 1.5 [SD]; range, 0.8-6.4 cm) were treated with percutaneous microwave coagulation therapy. Single electrode insertion was used in 46 nodules (43.0%) 2 cm or smaller, whereas multiple electrode insertion was applied in 61 (57.0%) nodules larger than 2 cm. RESULTS At 1 month after therapy, technical success for tumors 2 cm or smaller and those larger than 2 cm was achieved in 45 (98%) and 56 (92%) nodules, respectively. After follow-up of 9 months or longer, local recurrence was found in one nodule (2%) sized 1.8 cm and in five nodules (8%) larger than 2 cm. At the end of the study, 26 (52%) of 50 patients were free of disease, and disease-free survival rates at 1 and 2 years were 55% and 41%, respectively. Overall survival rates at 1, 2, and 3 years were 96%, 83%, and 73%, respectively. CONCLUSION Percutaneous microwave coagulation therapy is an effective and safe therapeutic modality for hepatocellular carcinoma. A multiple electrode insertion technique can enhance the effectiveness of this therapy in tumors 6 cm or smaller.

Abstract
PURPOSE Using the color Doppler velocity profile (CDVP), we investigated portal hemodynamics and their relationship with esophageal variceal bleeding (EVB) in patients with cirrhosis and portal hypertension. METHODS The hemodynamics of the portal trunk, right anterior portal branch, and splenic vein were evaluated in 69 cirrhotic patients with portal hypertension and 46 healthy volunteers. The CDVP, a recently developed Doppler software, was used to measure blood flow velocity and flow volume; evaluate the spatial distribution of flow velocities in the cross-section of a vessel (velocity profile), as reflected by the profile parameter (n); and assess changes in flow volume over time (flow profile). The congestion index was calculated by dividing the cross-sectional area by the maximum cross-sectional velocity (CSVmax). The hemodynamic features were compared between patients without a history of EVB [EVB(-)] and those with a history of EVB [EVB(+)], and a logistic regression model was employed to identify factors associated with EVB. RESULTS Compared with the healthy group, the cirrhotic group had a significantly lower mean CSVmax in the portal trunk and right anterior portal branch (both p < 0.01), a significantly elevated mean flow volume in the splenic vein and portal trunk (both p < 0.01), a significantly elevated mean ratio of splenic vein flow volume to portal trunk flow volume (SV/PT) (p < 0.001), and a significantly greater mean congestion index in the portal trunk, right anterior portal branch, and splenic vein (all p < 0.01). In the cirrhotic group, there was a significantly higher incidence of a flat flow pattern in the right anterior portal branch and a phasic flow pattern in the splenic vein than in the healthy group (both p < 0.01). Among cirrhotic patients, the EVB(+) group had a significantly greater mean flow volume in the splenic vein (p < 0.01), greater mean SV/PT (p < 0.01), greater mean spleen size (p < 0.05), and lower mean portal trunk n value (p < 0.05) compared with the EVB(-) group. Logistic regression analysis revealed that the SV/PT and portal trunk n value were independent EVB-related factors. CONCLUSIONS The results suggest that portal hemodynamics in cirrhotic patients are characterized by passive congestion and increased blood flow. However, these 2 features had different preponderances in different parts of the portal venous system. Increased flow in the splenic vein may be the primary source of increased portal flow and may play a role in the development of EVB. The SV/PT and portal trunk n value may be valuable factors for predicting EVB.

Abstract
The efficacy and safety of amphotericin B colloidal dispersion (ABCD; Amphotec, Sequus Pharmaceuticals, Menlo Park, CA), a lipid complex of amphotericin B, were evaluated in immunocompromised patients with candidemia. These patients were recruited from five open-label clinical trials of ABCD therapy for fungal infections subsequent to bone marrow transplantation, hematologic malignancies, solid tumors, solid-organ transplantation, or other severe underlying disorders. ABCD was given intravenously in a median daily dose of 3.9 mg/kg for < or =72 days. Response rates were as follows: 53% overall (n = 88), 66% for patients with candidemia alone (n = 67), and 14% for patients with disseminated candidemia (n = 21). Nephrotoxicity occurred in 16% of patients, with either doubling of the baseline serum creatinine level or an increase of > or =1 mg/dL or a > or =50% decrease in calculated creatinine clearance. On average, there were no significant changes in the levels of serum creatinine or bilirubin from baseline to the end of treatment. In conclusion, ABCD was safe and effective for treating immunocompromised patients with candidemia.

Abstract
PURPOSE A phase II study of liposomal doxorubicin was conducted in patients with ovarian cancer who failed to respond to platinum- and paclitaxel-based regimens. Liposomal doxorubicin was selected as a result of its superior activity against ovarian cancer xenografts relative to free doxorubicin and activity in refractory ovarian cancer patients that was noted during the phase I study. PATIENTS AND METHODS Thirty-five consecutive patients were accrued in two institutions (22 in one and 13 in the other). All had progressive disease after either cisplatin or carboplatin and paclitaxel, or at least one platinum-based and one paclitaxel-based regimen. Patients received intravenous (I.V.) liposomal doxorubicin 50 mg/m2 every 3 weeks with a dose reduction to 40 mg/m2 in the event of grade 3 or 4 toxicities, or a lengthening of the interval to 4 weeks (and occasionally to 5 weeks) with persistence of grade 1 or 2 toxicities beyond 3 weeks. RESULTS Nine clinical responses (one complete response [CR], eight partial responses [PRs]) were observed in 35 patients (25.7%), with seven of these having been confirmed by two consecutive computed tomographic (CT) measurements. The median progression-free survival was 5.7 months with an overall survival of 1.5 to 24+ months (median, 11 months). Although 13 patients experienced grade 3 or 4 nonhematologic skin and mucosal toxicities (either hand-foot syndrome or stomatitis), with dose modifications, the treatment was very well tolerated. Nausea that was clearly attributable to the drug, hair loss, extravasation necrosis, or decreases in ejection fraction did not occur. CONCLUSION Liposomal doxorubicin has substantial activity against ovarian cancer refractory to platinum and paclitaxel. The responses achieved with liposomal doxorubicin were durable and maintained with minimal toxicity. This liposomal formulation should be evaluated further in combination with other drugs in less refractory patients.

An embolization of the left central and lateral lobes was undertaken with various doses of absolute (95%) ethanol. The smallest dose, 0.25 ml/kg ethanol (n = 7), caused the least damage to the liver, but the embolization was not complete. At the highest dose at 1.0 ml/kg, four of the seven dogs died of respiratory arrest; however, embolization was complete in the remaining dogs. All animals tolerated the procedure by 0.5 ml/kg ethanol (n = 11) with a satisfactory embolic effect, slight toxicity to the hepatic parenchyma, and only transient changes in liver function. The results suggested that PVEEI is safe and effective when a suitable dose of ethanol is administered. Local overembolization occurred in one dog due to extension of the thrombus, suggesting that the point of puncture should not be near the confluence of the branches. Since a selective portal venous puncture is not difficult to perform under sonographic guidance, PVEEI is expected to be clinically applied.

Abstract
This paper introduced a technique of portal vein embolization by injection of ethanol via fine needle under guidance of angio-echography. First introportal ethanol injection were done in 28 dogs to evaluate its embolic efficacy and safety. The result showed if a dose of injected ethanol was chosen properly, expected embolization could be obtained with slight toxicity to hepatic parenchyma and function. For clinical application, selective portal vein puncture was percutaneous transhepatic under echo guidance. Ultrasound angiography by injecting carbon dioxide (CO2) into portal vein was introduced initially. After confirmed that the injected branch was that supplied the tumor and there was no retrograde overflow of portal blood, ethanol was injected at a dose no more than 10ml. Eighteen patients with hepatocellular carcinoma and underlying liver cirrhosis underwent the procedure preoperatively. Of 14 cases who received hepatectomies, portal vein embolization developed in 12. Since the procedure was guided by angio-echography it could be used for indicated cases with satisfactory embolic effect and not harmful to liver. The procedure had advantages of simple manipulation and made selective embolization easier compared to interventional transcatheter portal vein embolization.

Abstract
We performed two-stage resection for thirteen patients with advanced hepatocellular carcinoma from January 1987 to January 1991. All patients underwent various surgical therapies prior to resection which included gauze packing hemostasis in 1 case, hyperthermia plus radiotherapy in 1, hepatic arterial ligation in 2, operative hepatic arterial embolization in 1, and transcatheter embolization in 8. The median interval between the first therapy and tumor resection was 54 days with a range of 29-769 days and the median diameter of tumors decreased from 10.5 cm to 7.5 cm. The majority of procedures on two-stage resection were irregular hepatectomy or lobectomy under occlusion of porta hepatis. Regular hepatectomies were done in 4 cases. Pathological examination showed complete coagulation necrosis in 3 specimens. However, in the others were still found residual viable tumor cells outside or beneath the tumor capsule with varying degrees of necrosis within the tumors. Survival periods of the patients who received two-stage resection were from 4 months to 4 years except 2 operative death. The significance, possibility as well as methods of two-stage resection were discussed.

Abstract
Seventy transcatheter hepatic artery chemoembolizations with an emulsion containing iodized oil, adriamycin and 5-Fu were undertaken for the treatment of primary liver cancer in 58 patients and secondary liver cancer in 2 patients. The oil emulsion was selectively lodged in tumor vessels and small daughter nodules not detected by angiography or computed tomography prior to the chemoembolization Following the procedure, liver tumors appeared as areas of markedly high density on CT Hepatectomy performed on 3 of these cases following the chemoembolization found complete necrosis of the tumor in 2. The cumulative one-and two-year survival rates were 35.5% and 24.1% respectively. The results we have got indicate that the chemoembolization is a useful palliative measure for the treatment of hepatic neoplasms.
