Abstract
To investigate the serological and genetic characteristics of para-Bombay patients in a hospital in Hunan Province. A retrospective analysis was conducted on the blood type results of 175 439 hospitalized patients born in Hunan Province from the Third Xiangya Hospital, Central South University from 2016 to 2021. Phenotypes of ABO blood group was analyzed by blood group serology, and molecular biological methods were used to analyze the genotype, including ABO genotyping by polymerase chain reaction-sequence specific primers (PCR-SSP) and fucosyltransferase 1 (FUT1) and fucosyltransferase 2 (FUT2) gene sequencing. The results showed that 3 cases of Ah and 1 case of Bh were detected. FUT1 sequencing showed that there were 2 cases of h3h3, 1 case of h1h1 and 1 case of h302h1, of which h302 (c.302C>T) was the first discovered mutation. FUT2 sequencing revealed that 4 cases were all Se357Se357. The pedigree study showed that the inheritance of para-Bombay blood group was consistent with autosomal dominant inheritance. In conclusion, the FUT1 gene mutations leading to para-Bombay blood group mainly include h3, h1 and h302, of which h3 mutation is the most common.

Abstract
Kuntai capsules are effective in controlling primary ovarian insufficiency (POI). However, the precise mechanisms underlying the pharmacological effects of Kuntai capsules remain unclear. This study aimed to screen the active components and underlying mechanisms of Kuntai capsules for POI treatment using network pharmacology protocols and molecular docking technology. Potential active constituents in the chemical composition of Kuntai capsules were obtained from the Traditional Chinese Medicine System Pharmacology Database. Targets for POI were obtained from the Online Mendelian Inheritance in Man and Gene Cards database. All target data were integrated to identify the active ingredients of POI treatment. Enrichment analyses were performed using the Database for Annotation, Visualization, and Integrated Discovery database. The STRING database and Cytoscape software were used for protein-protein interaction network construction and core target identification. Finally, a molecular docking analysis of the active components and core targets was performed. A total of 157 ingredients related to POI were identified. Enrichment analysis showed that these components might participate in the mitogen-activated protein kinase, tumor necrosis factor, phosphoinositide-3-kinase/AKT serine/threonine kinase 1, and forkhead box O signaling pathways. Further protein-protein interaction network analysis revealed that the core targets were Jun proto-oncogene, AKT serine/threonine kinase 1, tumor protein P53, interleukin 6, and the epidermal growth factor receptor. Molecular docking analysis showed that baicalein was the most active ingredient with the highest affinity for the core targets. This study identified baicalein as the core functional component and elucidated the potential pharmacological effects of Kuntai capsule in the treatment of POI.

Abstract
Objective: To explore the correlation between polycyclic aromatic hydrocarbons (PAHs) component phenanthrene and clinical indicators in patients on continuous ambulatory peritoneal dialysis (CAPD). Methods: A total of 22 patients who underwent peritoneal dialysis catheterization and regular dialysis in the First Affiliated Hospital of Zhengzhou University from June to August 2018 were selected. Meanwhile, 18 healthy adults who underwent physical examination were also selected as the control group. Fasting blood samples were taken to detect the concentration of PAHs components for comparison, and the correlation between PAHs components and clinical indicators was further analyzed. Results: There were 22 cases in CAPD group (13 males and 9 females), and aged (45±13) years, while there were 18 cases in control group (6 males and 12 females), and aged (41±13) years. The concentration of blood phenanthrene (PHE) was the highest in CAPD group [0.449 (0.254, 0.581) mg/L], and it was only lower than acenaphthene in the control group [0.081 (0.050, 0.444) mg/L], with a statistically significant difference between the two groups (P=0.008). The analysis of PHE and clinical indicators showed that the concentration of PHE in CAPD patients was negatively correlated with weekly urea clearance index (Kt/V), weekly creatinine clearance (Ccr) and leukocyte level, but positively correlated with triglyceride level (r=-0.743, -0.749, -0.655 and 0.610, respectively, all P<0.05). Simple linear regression analysis demonstrated that for every 0.1 mg/L increase in PHE concentration, weekly Kt/V, weekly Ccr and white blood cell count decreased by 0.226, 3.050 L/1.73 m2 and 0.512×109/L, respectively, but triglyceride level increased by 0.152 mmol/L (all P<0.05). Multiple linear regression analysis revealed that the blood PHE concentration of CAPD patients was negatively correlated with weekly Kt/V and Ccr levels (t=-2.402 and -2.368, respectively, both P<0.05). All CAPD patients were followed up for 3 years, during which 8 patients (36.4%) withdrew from peritoneal dialysis due to technical failure, and the baseline PHE concentration was higher than that of patients who did not quit peritoneal dialysis [0.572 (0.416, 0.662) vs 0.268 (0.120, 0.475) mg/L, P=0.003]. Eight patients (36.4%) had cardiovascular events, and the baseline blood PHE concentration was higher than that of patients without cardiovascular events [0.542 (0.389, 0.741) vs 0.373 (0.157, 0.545) mg/L, P=0.045]. Conclusion: PHE correlates with clinical indicators of CAPD patients, including Kt/v, Ccr, leukocyte and triglyceride.

Abstract
OBJECTIVE To provide basic data for clinical application and individualized design of lumbar disc prostheses by measuring the anatomical parameters of lumbar intervertebral discs and endplates in healthy adults with CT three-dimensional reconstruction technology. METHODS A retrospective analysis was performed on 200 males and 200 females with normal lumbar spine who were admitted to the imaging center or outpatient department of the Second Affiliated Hospital of Xinjiang Medical University from September 2019 to December 2020. The age ranged from 20 to 60 years old, with an average of (40.61±11.22) years old. The measurement segment was L1-S1 intervertebral disc, and the measurement indicators included the axial anteroposterior diameter and transverse diameter of the intervertebral disc, sagittal anterior, middle and posterior height, coronal left and right height, intervertebral space angle, and transverse and anteroposterior diameters of the upper and lower endplates of each vertebral body. RESULTS ①In terms of gender, the anatomical parameters of L1-S1 disc axial diameter, transverse diameter, sagittal anterior, middle and posterior height, left and right coronal height and intervertebral space angle were all higher in males than in females(P<0.05), and the anatomical parameters of upper and lower endplates of L1-S1 vertebral body were higher in males than in females(P<0.001). ②In comparison of sagittal height of anterior, middle and posterior intervertebral discs, the sagittal height of L1-L5 intervertebral discs was middle-high > anterior-high > posterior-high(P<0.001), while that of L5S1 intervertebral disc was anterior-high > middle-high > posterior-high (P<0.001). ③In the comparison of left and right coronal height, there was no statistical significance in the left and right coronal height of L1-S1 disc between male and female(P>0.05). ④The L1-S1 intervertebral spaces angle between male and female increased with the increase of vertebral body segments. ⑤The anterior and posterior diameters and transverse diameters of upper and lower of L1-S1 vertebral bodies endplates were height in males than in females(P<0.001). CONCLUSION The results suggest that gender differences should be considered in the design of adult lumbar disc prostheses. The anatomical parameters of the lumbar intervertebral disc varied with the increase of the vertebral body sequence, suggesting that different anatomical parameters of the intervertebral disc should be considered in the design of the artificial intervertebral disc, and the changes in the height of the sagittal position suggest that the design of the intervertebral disc should be wedge-shaped.

Abstract
Corona Virus Disease 2019 (COVID-19), an acute respiratory infectious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has spread rapidly worldwide, resulting in a pandemic with a high mortality rate. In clinical practice, we have noted that many critically ill or critically ill patients with COVID-19 present with typical sepsis-related clinical manifestations, including multiple organ dysfunction syndrome, coagulopathy, and septic shock. In addition, it has been demonstrated that severe COVID-19 has some pathological similarities with sepsis, such as cytokine storm, hypercoagulable state after blood balance is disrupted and neutrophil dysfunction. Considering the parallels between COVID-19 and non-SARS-CoV-2 induced sepsis (hereafter referred to as sepsis), the aim of this study was to analyze the underlying molecular mechanisms between these two diseases by bioinformatics and a systems biology approach, providing new insights into the pathogenesis of COVID-19 and the development of new treatments. Specifically, the gene expression profiles of COVID-19 and sepsis patients were obtained from the Gene Expression Omnibus (GEO) database and compared to extract common differentially expressed genes (DEGs). Subsequently, common DEGs were used to investigate the genetic links between COVID-19 and sepsis. Based on enrichment analysis of common DEGs, many pathways closely related to inflammatory response were observed, such as Cytokine-cytokine receptor interaction pathway and NF-kappa B signaling pathway. In addition, protein-protein interaction networks and gene regulatory networks of common DEGs were constructed, and the analysis results showed that ITGAM may be a potential key biomarker base on regulatory analysis. Furthermore, a disease diagnostic model and risk prediction nomogram for COVID-19 were constructed using machine learning methods. Finally, potential therapeutic agents, including progesterone and emetine, were screened through drug-protein interaction networks and molecular docking simulations. We hope to provide new strategies for future research and treatment related to COVID-19 by elucidating the pathogenesis and genetic mechanisms between COVID-19 and sepsis.

Abstract
Plastic deformation in crystalline materials occurs through dislocation slip and strengthening is achieved with obstacles that hinder the motion of dislocations. At relatively low temperatures, dislocations bypass the particles by Orowan looping, particle shearing, cross-slip or a combination of these mechanisms. At elevated temperatures, atomic diffusivity becomes appreciable, so that dislocations can bypass the particles by climb processes. Climb plays a crucial role in the long-term durability or creep resistance of many structural materials, particularly under extreme conditions of load, temperature and radiation. Here we systematically examine dislocation-particle interaction mechanisms. The analysis is based on three-dimensional discrete dislocation dynamics simulations incorporating impenetrable particles, elastic interactions, dislocation self-climb, cross-slip and glide. The core diffusion dominated dislocation self-climb process is modelled based on a variational principle for the evolution of microstructures, and is coupled with dislocation glide and cross-slip by an adaptive time-stepping scheme to bridge the time scale separation. The stress field caused by particles is implemented based on the particle-matrix mismatch. This model is helpful for understanding the fundamental particle bypass mechanisms and clarifying the effects of dislocation glide, climb and cross-slip on creep deformation.

Abstract
Hypoxia is one of the important pathophysiologic causes of ED, and the development and progression of hypoxia-induced ED can be attributed to multiple factors relating nerves, blood vessels, endocrine and various cytokines. The mechanisms of hypoxia-induced ED have not been fully clarified by now despite some advances achieved in the respects of corpus cavernosal microstructure, important signaling pathways, oxidative stress, hormone levels, autophagy and so on. This review focuses on the present status of and progress made in the studies of hypoxia-induced ED in order to provide some evidence and a direction for further researches.

Abstract
INTRODUCTION Smoking is well-known to increase cancer risk, particularly risk of lung cancer, and negatively affects efficacy of cancer treatment. However, recent evidence suggests that among cancer patients, paradoxically, smokers respond to treatment better than non-smokers. We propose to conduct a focused review and meta-analysis to compare response to drug treatment between smoking and non-smoking cancer patients. METHODS AND DESIGN We will collect data from large clinical trials of therapies for cancer patients which have included smokers and non-smokers. We will search PubMed, PMC/ MEDLINE, SCOPUS, Embase, and the registries for clinical trials and four major clinical journals up to June 30, 2019. Search terms will be "Drug name" phase-3" or "Drug name" phase-III." Data collection will be focused on randomized clinical trials of cancer drugs that enrolled at least 100 participants and reporting treatment results from smoking and nonsmoking patients. Initial selection criteria will be clinical trial studies of drug treatment of 100 or more cancer patients, and reporting hazard ratios (HR) for smokers and non-smokers. Two persons will be searching such publications independently, or data will be provided, double checked, or confirmed by authors. Multiple sub-group analyses will be conducted by at least two persons to avoid bias or experimental errors. DISCUSSION The results will clarify whether smoking and response to treatment of cancer are linked not. Our results may possibly identify drug/s that work better among cancer patients who are smokers. TRIAL REGISTRATION PROSPERO registration number: CRD42019146402.

Abstract
Objective: To explore the clinical features and prognosis of gastric mucosa-associated lymphoid tissue lymphoma. Methods: The data of patients with gastric mucosa-associated lymphoid tissue lymphoma diagnosed and treated at Peking University Cancer Hospital from 2000 to 2019 were collected, and their clinical characteristics, treatment options and effects, and prognosis were retrospectively analyzed. Results: The median age of 68 patients was 56 years old, and the ratio of men to women was 0.6∶1.0. Early patients accounted for about 76% (52/68). The most commonly used treatment is Helicobacter pylori eradication, followed by radiotherapy and chemotherapy. The total effective rate is 94%, of which the complete remission rate is 72%. With a median follow-up of 44 months, the 5-year progression-free survival (PFS) rate was 73%, and the overall survival (OS) rate was 83%. Prognostic factor analysis showed that albumin level (P=0.011) and international prognostic index (IPI)(P=0.017) are independent prognostic indicators of PFS, The 5-year PFS rate of patients with normal and reduced albumin was 77% and 50%, respectively, and the 5-year PFS rate of patients with IPI score<2 points and IPI ≥ 2 points was 80% and 48%, respectively. Lactate dehydrogenase (LDH) (P=0.016) and albumin level (P=0.025) are independent prognostic indicators of OS, and the 5-year OS rates of patients with normal and elevated LDH were 87% and 67%, respectively. The 5-year OS rates of patients with normal albumin and reduced were 92% and 73%, respectively. Conclusions: Gastric mucosa-associated lymphoid tissue lymphoma is sensitive to treatment and has a good prognosis. The patient's albumin and lactate dehydrogenase levels are independent prognostic indicators.

Abstract
BACKGROUND Mesenchymal stem cells (MSCs) have been widely investigated in rheumatic disease due to their immunomodulatory and regenerative properties. Recently, mounting studies have implicated the therapeutic potency of MSCs mostly due to the bioactive factors they produce. Extracellular vesicles (EVs) derived from MSCs have been identified as a promising cell-free therapy due to low immunogenicity. Rheumatic disease, primarily including rheumatoid arthritis and osteoarthritis, is a group of diseases in which immune dysregulation and chronic progressive inflammation lead to irreversible joint damage. Targeting MSCs and MSC-derived EVs may be a more effective and promising therapeutic strategy for rheumatic diseases.
AIM To evaluate the potential therapeutic effectiveness of MSCs and EVs generated from MSCs in rheumatic diseases.
METHODS PubMed was searched for the relevant literature using corresponding search terms alone or in combination. Papers published in English language from January 1999 to February 2020 were considered. Preliminary screening of papers concerning analysis of "immunomodulatory function" or "regenerative function" by scrutinizing the titles and abstracts of the literature, excluded the papers not related to the subject of the article. Some other related studies were obtained by manually retrieving the reference lists of papers that comply with the selection criteria, and these studies were screened to meet the final selection and exclusion criteria.
RESULTS Eighty-six papers were ultimately selected for analysis. After analysis of the literature, it was found that both MSCs and EVs generated from MSCs have great potential in multiple rheumatic diseases, such as rheumatoid arthritis and osteoarthritis, in repair and regeneration of tissues, inhibition of inflammatory response, and regulation of body immunity via promoting chondrogenesis, regulating innate and adaptive immune cells, and regulating the secretion of inflammatory factors. But EVs from MSCs exhibit much more advantages over MSCs, which may represent another promising cell-free restorative strategy. Targeting MSCs and MSC-derived EVs may be a more efficient treatment for patients with rheumatic diseases.
CONCLUSION The enormous potential of MSCs and EVs from MSCs in immunomodulation and tissue regeneration offers a new idea for the treatment of rheumatism. However, more in-depth exploration is needed before their clinical application.

Abstract
OBJECTIVE To study of the regulatory effects of the lipid metabolic pathways of trimethylamine-N-oxide (TMAO), flavin-containingmonooxidase 3 (FMO3) and farnesoid X receptor (FXR) on compound stress-induced ED (CSED) rats and the mechanisms of Yimusake Tablets (YMSK) intervention. METHODS Based on the results of metabonomics analysis, we determined the concentration of TMAO in the serum of the rats in the normal control (n = 30), the CSED model control (n = 30) and the YMSK intervention group (intragastrical administration of YMSK at 250 mg/kg once daily for 2-3 weeks after modeling, n = 30) by nuclear magnetic resonance (NMR) spectroscopy test. We also detected the expressions of the FMO3, FXR1 and FXR2 proteins in the liver tissue of the three groups of rats by Western blot. RESULTS The serum TMAO level was significantly elevated in the CSED model control compared with that in the normal control group ([46.64 ± 5.16] vs [34.98 ± 3.69] μg/mL, P < 0.01) but remarkably decreased after YMSK intervention ([39.63 ± 4.81] μg/mL) in comparison with that in the CSED model control group (P < 0.01). The rats in the CSED model control group, compared with the normal controls, showed significantly upregulated expressions of FMO3 (1.75 ± 0.90 vs 0.86 ± 0.62, P < 0.01),FXR1 (1.29 ± 0.38 vs 0.78 ± 0.25, P < 0.01) and FXR2 in the liver tissue (1.90 ± 0.63 vs 0.42 ± 0.27, P < 0.01), but all the three expressions were markedly decreased after YMSK intervention (FMO3: 1.05 ± 0.38, P < 0.05; FXR1: 1.07 ± 0.42, P < 0.05; FXR2: 1.04 ± 0.46, P < 0.01) as compared with those in the CSED model control group. CONCLUSIONS The lipid metabolic pathways of TMAO, FMO3 and FXR underwent significant changes in the rat model of compound stress-induced ED, which could be improved by YMSK intervention, suggesting that YMSK may play an important role in protecting erectile function by regulating the lipid metabolic pathways of TMAO, FMO3 and FXR.

Abstract
Methamphetamine is one of the most prevalent drugs abused in the world. Methamphetamine abusers usually present with hyperpyrexia (39°C), hallucination and other psychiatric symptoms. However, the detailed mechanism underlying its neurotoxic action remains elusive. This study investigated the effects of methamphetamine + 39°C on primary cortical neurons from the cortex of embryonic Sprague-Dawley rats. Primary cortex neurons were exposed to 1 mM methamphetamine + 39°C. Propidium iodide staining and lactate dehydrogenase release detection showed that methamphetamine + 39°C triggered obvious necrosis-like death in cultured primary cortical neurons, which could be partially inhibited by receptor-interacting protein-1 (RIP1) inhibitor Necrostatin-1 partially. Western blot assay results showed that there were increases in the expressions of receptor-interacting protein-3 (RIP3) and mixed lineage kinase domain-like protein (MLKL) in the primary cortical neurons treated with 1 mM methamphetamine + 39°C for 3 hours. After pre-treatment with RIP3 inhibitor GSK’872, propidium iodide staining and lactate dehydrogenase release detection showed that neuronal necrosis rate was significantly decreased; RIP3 and MLKL protein expression significantly decreased. Immunohistochemistry staining results also showed that the expressions of RIP3 and MLKL were up-regulated in brain specimens from humans who had died of methamphetamine abuse. Taken together, the above results suggest that methamphetamine + 39°C can induce RIP3/MLKL regulated necroptosis, thereby resulting in neurotoxicity. The study protocol was approved by the Medical Ethics Committee of the Third Xiangya Hospital of Central South University, China (approval numbers: 2017-S026 and 2017-S033) on March 7, 2017.

Abstract
The study aimed to determine the effects of methionine hydroxy analog chelate zinc on the tibia quality, mineral deposit, apparent retention of nutrients, and liver metallothionein (MT) expression level of aged laying hens. A total of 960 layers (Hy-Line Grey, 57 wk old) were randomly assigned into 4 groups, and each group had 8 replicates of 30 hens. During the first 2 wk, groups were fed a basal diet without extra zinc (Zn: 35.08 mg/kg). During the ensuing 14 wk, 4 levels of Zn (inorganic Zn: 80 mg/kg; organic Zn: 20, 40, 80 mg/kg) were added to the diet. The results indicated that both the Zn source and level did influence tibia strength and calcium (Ca) and Zn concentrations of tibia (P < 0.05), whereas there were no differences in the copper (Cu) and phosphorus (P) concentrations of the tibia and the tibia length (P > 0.05). Moreover, dietary supplementation with 40 or 80 mg/kg of organic Zn showed higher Zn and Ca concentrations in the tibia and higher tibia strength. The Cu concentration in the liver showed no difference among the 4 treatments, whereas the Zn concentration in the liver increased with the increasing Zn level. The apparent retention of P, iron (Fe), and manganese (Mn) was not affected by the Zn level or source (P > 0.05). However, the organic Zn group increased the apparent retention of Cu, Zn, Ca, crude protein (CP), and energy, and the group supplemented with 40 or 80 mg/kg of organic Zn obtained significant effects (P < 0.05). Moreover, dietary supplementation with 40 or 80 mg/kg organic Zn increased the MT mRNA expression of the liver at week 72, whereas 20 mg/kg of organic Zn decreased it (P < 0.05). In conclusion, this study suggested that an optimum dietary (40 mg/kg) organic Zn level plays a key role in promoting the apparent retention of minerals and nutrients, trace element deposit, and MT mRNA expression.

Abstract
OBJECTIVE To determine the expressions of calcitonin gene-related peptide (CGRP) and vasoactive intestinal peptide (VIP) in the penile tissue of the ED rat model and explore their action mechanisms. METHODS An ED model was established in 44 mature male SD rats by feeding them on a spinach + coriander diet in a cold-wet environment and another 10 were taken as normal controls. Then the model rats were randomly divided into an ED model control group (n = 15) treated by gavage of distilled water in the same modeling environment, a spontaneous recovery group (n = 15) treated by gavage of distilled water in the normal environment, and a medication group (n = 14) treated intragastrically with Yimusake Tablets at 250 mg/kg qd. After 2-3 weeks of intervention, the expressions of CGRP and VIP in the penile tissue were detected by immunohistochemistry and Western blot. RESULTS Immunohistochemistry showed that, after 2 weeks of intervention, both the expressions of CGRP and VIP in the rat penile tissue were significantly lower in the ED model control (150.0 ± 43.3 and 36.4 ± 13.1) and the spontaneous recovery group (165.9 ± 40.7 and 67.5 ± 29.0) than in the normal control (227.3 ± 42.5 and 175.0 ± 45.6) (P < 0.05), but remarkably higher in the medication group (255.0 ± 38.7 and 167.5 ± 42.6) than those in the ED model control and spontaneous recovery groups (P < 0.05). CONCLUSIONS The expressions of CGRP and VIP were significantly down-regulated in the ED rat model, and Yimusake Tablets improved ED by up-regulating their expressions.

Abstract
In recent years, male infertility has received more and more attention from scholars at home and abroad. Asthenospermia is one of the common causes of male infertility, the main manifestation of which is low sperm motility. Current studies show that the pathogenic factors for asthenospermia are complex and diverse, including gene mutations, alteration of ion channels, oxidative stress, changes in the contents of trace elements, and others. Despite the progress made in the related researches, the mechanisms underlying the pathogenesis of asthenospermia have not yet been fully elucidated. With a review of the recent relevant literature published at home and abroad, this article presents an overview on the related gene mutations, alteration of ion channels, changes in the levels of proteins, epigenetics, and other molecular biological mechanisms underlying the pathogenesis of asthenospermia, hoping to provide some evidence for the clinical diagnosis and treatment of asthenospermia.

Abstract
Mutations in the COL4A5 gene result in X-linked Alport syndrome, homozygous or compound heterozygous mutations in COL4A3 or COL4A4 are responsible for autosomal recessive Alport syndrome, and heterozygous mutations in COL4A3 or COL4A4 cause autosomal dominant Alport syndrome or benign familial hematuria. Recently, the existence of a digenic inheritance in Alport syndrome has been demonstrated. We here report heterozygous COL4A3 and COL4A4 digenic mutations in cis responsible for benign familial hematuria. Using bioinformatics analyses and pedigree verification, we showed that COL4A4 c.1471C>T and COL4A3 c.3418 + 1G>T variants in cis are pathogenic and co-segregate with the benign familial hematuria. This result suggests that COL4A3 and COL4A4 digenic mutations in cis mimicking an autosomal dominant inheritance should be considered as a novel inheritance pattern of benign familial hematuria, although the disease-causing mechanism remains unknown.

Abstract
Background Soil bacterium Sinorhizobium meliloti (S. meliloti) forms an endosymbiotic partnership with Medicago truncatula (M. truncatula) roots which results in root nodules. The bacteria live within root nodules where they function to fix atmospheric N2 and supply the host plant with reduced nitrogen. The bacterial RNA-binding protein Hfq (Hfq) is an important regulator for the effectiveness of the nitrogen fixation. RNA immunoprecipitation (RIP) method is a powerful method for detecting the association of Hfq protein with specific RNA in cultured bacteria, yet a RIP method for bacteria living in root nodules remains to be described. Results A modified S. meliloti gene encoding a His-tagged Hfq protein (HfqHis) was placed under the regulation of the native Hfq gene promoter (Phfqsm). The trans produced HfqHis protein was accumulated at its nature levels during all stages of the symbiosis, allowing RNAs that associated with the given protein to be immunoprecipitated with the anti-His antibody against the protein from root nodule lysates. RNAs that associated with the protein were selectively enriched in the immunoprecipitated sample. The RNAs were recovered by a simple method using heat and subsequently analyzed by RT-PCR. The nature of PCR products was determined by DNA sequencing. Hfq association with specific RNAs can be analyzed at different conditions (e. g. young or older root nodules) and/or in wild-type versus mutant strains. Conclusions This article describes the RIP method for determining Sinorhizobium meliloti RNA-Hfq associations in vivo. It is also applicable to other rhizobia living in planta, although some tissue-specific modification related to sample disruption and homogenization may be needed.

Abstract
Thin basement membrane nephropathy (TBMN), autosomal dominant Alport syndrome (ADAS), and focal segmental glomerulosclerosis (FSGS) are kidney diseases that differ in clinical diagnosis, treatment, and prognosis. Nevertheless, they may result from the same causative genes. Here, we report 3 COL4A4 heterozygous mutations (p.Gly208Arg, p.Ser513Glufs*2, and p.Met1617Cysfs*39) that lead to 3 different collagen type IV kidney disease phenotypes, manifesting as TBMN, ADAS, and FSGS. Using bioinformatics analyses and pedigree verification, we show that these novel variants are pathogenetic and cosegregate with TBMN, ADAS, and FSGS. Furthermore, we found that the collagen type IV-associated kidney disease phenotypes are heterogeneous, with overlapping pathology and genetic mutations. We propose that COL4A4-associated TBMN, ADAS, and FSGS should be considered as collagen type IV kidney disease subtypes that represent different phases of disease progression.

Abstract
This study developed a partial nitrification (PN) and anaerobic ammonia oxidation (Anammox) process for treating high-ammonia wastewater using an innovative biofilm system in which ammonia oxidizing bacteria grew on fluidized Kaldnes (K1) carriers and Anammox bacteria grew on fixed acryl resin carriers. The airlift loop biofilm reactor (ALBR) was stably operated for more than 4 months under the following conditions: 35 ± 2 °C, pH 7.5-8.0 and dissolved oxygen (DO) of 0.5-3.5 mg/L. The results showed that the total nitrogen removal efficiency reached a maximum of 75% and the total nitrogen removal loading rate was above 0.4 kg/(d·m3). DO was the most efficient control parameter in the mixed biofilm system, and values below 1.5 mg/L were observed in the riser zone for the PN reaction, while values below 0.8 mg/L were observed in the downer zone for the Anammox reaction. Scanning electron microscopy and Fluorescence In Situ Hybridization images showed that most of the nitrifying bacteria were distributed on the K1 carriers and most of the Anammox bacteria were distributed within the acryl resin carriers. Therefore, the results indicate that the proposed combined biofilm system is easy to operate and efficient for the treatment of high-ammonia wastewater.

Abstract
Necroptosis is programmed necrosis, a process which has been studied for over a decade. The most common accepted mechanism is through the RIP1-RIP3-MLKL axis to regulate necroptotic cell death. As a result of previous studies on necroptosis, positive regulation for promoting necroptosis such as HSP90 stabilization and hyperactivation of TAK1 on RIP1 is clear. Similarly, the negative regulation of necroptosis, such as through caspase 8, c-FLIP, CHIP, MK2, PELI1, ABIN-1, is also clear. Therefore, the promise of corresponding applications in treating diseases becomes hopeful. Studies have shown that necroptosis is involved in the development of many diseases, such as ischemic injury diseases in various organs, neurodegenerative diseases, infectious diseases, and cancer. Given these results, drugs that inhibit or trigger necroptosis can be discovered to treat diseases. In this review, we briefly introduce up to date concepts concerning the mechanism of necroptosis, the diseases that involve necroptosis, and the drugs that can be applied to treat such diseases.

Abstract
This study aimed to analyze the correlation of the plasminogen activator inhibitor (PAI-1) gene polymorphisms (rs6092 and rs7242) with susceptibility of osteonecrosis of the femoral head (ONFH).This case-control study included 106 ONFH patients and 151 healthy controls. PAI-1 polymorphisms were genotyped by polymerase chain reaction (PCR) with direct sequencing. The genotype distribution of polymorphism in the control group was checked with the status of Hardy-Weinberg equilibrium (HWE). The χ test was applied to compare the genotypes of polymorphisms between the case and control groups. The association intensity between PAI-1 polymorphisms and ONFH risk was estimated by odds ratios (ORs) and 95% confidence intervals (95% CI). The linkage disequilibrium of PAI-1 polymorphisms was analyzed by Haploview.We found that the genotypes and alleles of PAI-1 rs6092 and rs7242 polymorphisms had no obvious association with the risk of ONFH (P >.05). But the strong linkage disequilibrium existed between rs6092 and rs7242 polymorphisms and haplotype G-T was significantly associated with the decreased risk of ONFH occurrence (OR = 0.666, 95%CI = 0.445-0.998).PAI-1 rs6092 and rs7242 polymorphisms are not associated with ONFH development, but haplotype G-T may be a protective factor of ONFH.

Abstract
Objective: To investigate whether the co-culture of Huh7.93 cells and peripheral blood mononucleated cells from chronic hepatitis B patients (cPBMCs) can simulate the replication features of hepatitis B virus (HBV) and immune function in chronic hepatitis B (CHB) patients, and to provide an in vitro cell co-culture system for the research on immune clearance in chronic HBV infection. Methods: Huh7.93 cells were cultured alone or co-cultured with peripheral blood mononucleated cells from healthy people who underwent physical examination (nPBMCs) or cPBMCs for 7 days. The CCK8 assay was performed to measure the proliferative activity of Huh7.93 cells, and quantitative real-time PCR and Southern blot were used to measure HBV replication in cPBMCs and co-cultured cells. The independent samples t-test was used for comparison between two groups. Results: When Huh7.93 cells were co-cultured with peripheral blood mononucleated cells (PBMCs) at a certain ratio, Huh7.93 cells had a high proliferative activity and good cell growth. HBV could not infect or replicate in cPBMCs. HBV DNA in the supernatant of Huh7.93 cells co-cultured with cPBMCs showed significant increases and significantly higher than that in the supernatant of Huh7.93 cells cultured alone on day 4 (6.01 ± 0.20 log10copies/ml vs 4.99 ± 0.08 log10copies/ml, P = 0.000) and day 7 (7.82 ± 0.24 log10copies/ml vs 6.96±0.09 log10copies/ml, P = 0.000). On day 7 of culture, the cell lysis buffer of Huh7.93 cells co-cultured with cPBMCs had a significant increase in the level of HBV replicative intermediate compared with that of Huh7.93 cells cultured alone. After HepG2.2.15 cells were co-cultured with cPBMCs, there was no significant increase in HBV replication. Conclusion: The co-culture of Huh7.93 cells and cPBMCs produces similar viral replication as human body infected with HBV and can well simulate the liver microenvironment and immune function in CHB patients, which provides a new method for the research on immune clearance in chronic HBV infection.

Abstract
Background Visceral adipose tissue is more metabolically active than other fat depots and is more closely associated with obesity-related diseases, such as cardiovascular disease and type 2 diabetes, than indicators of obesity, such as body mass index. Across various strategies to promote weight loss, including energy-reduced diet and exercise, variable effects on VAT compared to loss of total body fat have been reported. Methods To examine the effect of a behavioral weight loss intervention using portion-controlled prepackaged entrées on VAT, we examined data and measurements from overweight/obese men and women (N=183) who were assigned to a weight loss intervention and prescribed a reduced-energy diet with either portion-controlled prepackaged entrées or self-selected meals in a randomized clinical trial. VAT was estimated with dual-energy X-ray absorptiometry at baseline and study end (12 weeks). Results VAT loss was greater for the prepackaged entrees group (p=0.02), with an average loss of 29% compared to an average loss of 19% among participants consuming self-selected meals. VAT (mean [SEM]) was 1651 (71) g and 1546 (157) g at baseline and 1234 (59) g and 1278 (118) g at study end in the prepackaged entrees and self-selected meal groups, respectively. Greater VAT loss was associated with higher baseline weight and VAT, and greater weight loss, but not associated with age or physical activity. Conclusion Prescribing portion-controlled prepackaged entrees in a behavioral weight loss intervention promotes a reduction in VAT, which should promote improved metabolic profile and reduced cardiovascular disease risk.

Abstract
BACKGROUND Drug-induced immune thrombocytopenia (DITP) is a serious, life-threatening clinical syndrome, the diagnosis of which is consistently difficult. In this report, we present a case of DITP caused by meropenem that was confirmed by laboratory tests. CASE REPORT A 59-year-old male patient developed severe thrombocytopenia 8 days after the administration of meropenem and cefoperazone-sulbactam. After other causes were ruled out, DITP was suspected. Drug-induced platelet (PLT) antibodies were detected by enzyme immunoassay, flow cytometry, and monoclonal antibody immobilization of PLT antigens (MAIPA). All these tests were performed in the presence and absence of the associated drugs. RESULTS PLT antibodies were detected in the patient's serum only in the presence of meropenem. MAIPA experiments demonstrated that glycoprotein IIb/IIIa was the binding site of the meropenem-induced PLT antibodies. CONCLUSIONS Drug-induced immune thrombocytopenia should be considered in cases of acute thrombocytopenia in patients undergoing meropenem treatment. Clinicians should be cognizant of DITP, and a definitive diagnosis should be pursued, if feasible.

Abstract
Alport syndrome (AS) is a clinically and genetically heterogeneous, progressive nephropathy caused by mutations in COL4A3, COL4A4, and COL4A5, which encode type IV collagen. The large sizes of these genes and the absence of mutation hot spots have complicated mutational analysis by routine polymerase chain reaction (PCR)-based approaches. Here, in order to design a rapid and effective method for the genetic diagnosis of AS, we developed a strategy by utilizing targeted capture associated with next-generation sequencing (NGS) to analyze COL4A3, COL4A4, and COL4A5 simultaneously in 20 AS patients. All the coding exons and flanking sequences of COL4A3, COL4A4, and COL4A5 from the probands were captured followed by HiSeq 2500 sequencing. Candidate mutations were validated by classic Sanger sequencing and quantitative (q)PCR. Sixteen patients (16/20, 75%) showed X-linked inheritance, and four patients (4/20, 20%) showed autosomal recessive inheritance. None of the individuals had autosomal-dominant AS. Fifteen novel mutations, 6 known mutations, and 2 novel fragment deletions were detected by targeted capture and NGS. Of these novel mutations, 12, 3, and 2 mutations were detected in COL4A5, COL4A4, and COL4A3, respectively. A comparison of the clinical manifestations caused by different types of mutations in COL4A5 suggested that nonsense mutations and glycine substitution by an acidic amino acid are more severe than the other missense mutations. Pathogenic mutations were detected in 20 patients. These novel mutations can expand the genotypic spectrum of AS. Our results demonstrated that targeted capture and NGS technology are effective in the genetic diagnosis of AS.

Abstract
Background: The dyschromatoses are a group of disorders characterized by simultaneous hyperpigmented macules together with hypopigmented macules. Dyschromatosis universalis hereditaria (DUH) and dyschromatosis symmetrica hereditaria are two major types. While clinical and histological presentations are similar in these two diseases, genetic diagnosis is critical in the differential diagnosis of these entities. Methods: Three patients initially diagnosed with DUH were included. The gene test was carried out by targeted gene sequencing. All mutations detected on ADAR1 and ABCB6 genes were analyzed according to the frequency in control database, the mutation types, and the published evidence to determine the pathogenicity. Results: Family pedigree and clinical presentations were reported in 3 patients from two Chinese families. All patients have prominent cutaneous dyschromatoses involving the whole body without systemic complications. Different pathogenic genes in these patients with similar phenotype were identified: One novel mutation on ADAR1 (c. 1325C>G) and one recurrent mutation in ABCB6 (c. 1270T>C), which successfully distinguished two diseases with the similar phenotype. Conclusion: Targeted gene sequencing is an effective tool for genetic diagnosis in pigmentary skin diseases.

Abstract
BACKGROUND End-stage renal disease (ESRD) is fatal if untreated. In the absence of transplant, approximately 50 % of dialysis patients die within 5 years. Although more frequent and/or longer haemodialysis (high-dose HD) improves survival, this regimen may add to the burden on dialysis services and healthcare costs. This systematic review summarised the cost effectiveness of high-dose HD compared with conventional HD. METHODS English language publications reporting the cost-utility/effectiveness of high-dose HD in adults with ESRD were identified via a search of MEDLINE, Embase, and the Cochrane Library. Publications comparing any form of high-dose HD with conventional HD were reviewed. RESULTS Seven publications (published between 2003 and 2014) reporting cost-utility analyses from the public healthcare payer perspective were identified. High-dose HD in-centre was compared with in-centre conventional HD in one US model; all other analyses (UK, Canada) compared high-dose HD at home with in-centre conventional HD (n = 5) or in-centre/home conventional HD (n = 1). The time horizon varied from one year to lifetime. Similar survival for high-dose HD and conventional HD was assumed, with the impact of higher survival only assessed in the sensitivity analyses of three models. High-dose HD at home was found to be cost effective compared with conventional HD in all six analyses. The analysis comparing high-dose HD in-centre with conventional in-centre HD produced an incremental cost-effectiveness ratio generally acceptable for the USA, but not for Europe, Canada or Australia. CONCLUSION High-dose HD can be cost effective when performed at home. Future analyses assuming survival benefits for high-dose HD compared with conventional HD are needed.

Abstract
Casticin is one of the main components of the fruits of Vitex rotundifolia L. Studies have shown that casticin inhibits the growth of various cancer cells, including colon cancer. In the present study, the anti-carcinogenic effects of casticin on human colon cancer and the underlying mechanisms were investigated. The results revealed that casticin significantly induced apoptosis of HT-29, HCT-116, SW480 and Caco-2 cells, induced the accumulation of reactive oxygen species (ROS) and increased the protein levels of apoptosis signal-regulating kinase 1 (ASK1), c-Jun N-terminal kinase (JNK) and B-cell lymphoma 2-interacting mediator of cell death (Bim) in HT-29 cells. Pretreatment with N-acetylcysteine, an antioxidant chemical compound, inhibited the activation of ASK1, JNK and Bim, as well as the apoptosis induced by casticin. Small interfering RNA targeting ASK1 significantly attenuated the induction of JNK and Bim activation and apoptotic cell death by casticin treatment. SP600125, a specific JNK inhibitor, attenuated Bim activation and apoptosis, but did not alter ASK1 phosphorylation levels. In addition, casticin treatment resulted in apoptosis by the same mechanism in HCT-116, SW480 and Caco-2 cells. These results suggest that casticin significantly induced apoptosis by the activation of the ASK1-JNK-Bim signaling cascade and the accumulation of ROS in colon cancer cells.

Abstract
This study was purposed to explore the suitable ratio between fresh frozen plasma and erythrocyte by retrospective analysis of coagulation in patients with massive blood transfusion. The clinical data of 151 cases with massive blood transfusion from January 2011 to January 2013 were analyzed retrospectively. According to coagulation, patients were divided into coagulation normal group (138 cases) and coagulation dysfunction group (13 cases). Based on the ratio of 1:1 of fresh frozen plasma and erythrocyte, the patients were divided into high plasma group(2:1), medium plasma group (1:1) and low plasma (<1:1) subgroups. Coagulation was detected before and after 24 h of massive blood transfusion. The results showed that prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) were prolonged, fibrinogen (FIB) level decreased significantly (all P < 0.05) in the low plasma subgroup of coagulation normal group after massive blood transfusion 24 h; the high plasma and the medium plasma group of coagulation normal group had no significant changes in coagulation (P > 0.05); prothrombin time, activated partial thromboplastin time, thrombin time and fibrinogen level in the medium plasma and low plasma subgroup of coagulation dysfunction group after massive transfusion was still in abnormal levels (P > 0.05), coagulation function in high plasma subgroup was improved significantly (P < 0.05). It is concluded that the ratio of plasma to erythrocyte should be adjusted according to the patient's coagulation function during massive blood transfusion, the ratio between fresh frozen plasma and erythrocyte is recommended to be 2:1 in patients of coagulation dysfunction in order to improve the patient's coagulation function and to reduce the incidence of adverse event, the ratio of fresh frozen plasma to erythrocyte is recommended to be 1:1 in patients with normal coagulation so as to reduce the dilutional coagulopathy and hypervolemia of blood.

Abstract
BACKGROUND Multiple epiphysis dysplasia (MED) is a common skeletal dysplasia with a significant locus heterogeneity. In the majority of clinically defined cases, mutations have been identified in the gene encoding cartilage algometric matrix protein (COMP). METHODS Five patients were included in the study. Linkage analysis and mutation analysis of the COMP gene were conducted in the patients and their family members. RESULTS We have identified a novel mutation in axon 14 of COMP gene in the family. CONCLUSIONS This mutation produced a severe MED phenotype with marked short stature, early onset osteoarthritis, and remarkable radiographic changes. Our results extended the range of disease-causing mutations in COMP gene and contributed more information about relationship between mutations and phenotype.

Abstract
Four principal mango cultivars (Tainong No.1, Irwin, JinHwang and Keitt) grown in southern China were selected, and their physico-chemical and antioxidant properties were characterized and compared. Of all the four cultivars, Tainong No.1 had highest content of total phenols, ρ-coumaric acid, sinapic acid, quercetin, titratable acidity, citric acid, malic acid, fructose, higher antioxidant activities (DPPH, FRAP) and L(*), lower pH, PPO activity and individual weight. Keitt mangoes showed significantly (p<0.05) higher contents of β-carotene, ρ-hydroxybenzoic acid, sucrose, total sugar, total soluble solid, catechin, succinic acid and higher PPO activity. JinHwang mangoes exhibited significantly (p<0.05) higher individual weight and PPO activity, but had lower content of total phenols, β-carotene and lower antioxidant activity. Principal component analysis (PCA) allowed the four mango cultivars to be differentiated clearly based on all these physico-chemical and antioxidant properties determined in the study.

Abstract
OBJECTIVES Parenteral nutrition (PN) is critical in neonatal and pediatric care for patients unable to tolerate enteral feeding. This study assessed the total costs of compounding PN therapy for neonates, infants and children. METHODS Face-to-face and telephone interviews were conducted in 12 hospitals across four European countries (Belgium, France, Germany and UK) to collect information on resources utilized to compound PN, including nutrients, staff time, equipment cost and supplies. A bottom-up cost model was constructed to assess total costs of PN therapy by assigning monetary values to the resource utilization using published list prices and interview data. RESULTS A total of 49,922 PN bags per year were used to treat 4295 neonatal and pediatric patients among these hospitals. The daily total costs of one compounded PN bag for neonates in the 12 hospitals across the four countries equalled euro 55.16 (Belgium euro 53.26, France euro 46.23, Germany euro 64.05, UK Ł 37.43/\[euro]42.86). Overall, nutrients accounted for 25% of total costs, supplies 18%, wages 54% and equipment 3%. Average costs per bag for infants <2 year were euro 84.52 (euro 74.65 in Belgium, euro 83.84 in France, euro 92.70 in Germany and Ł 52.63/euro 60.26 in the UK), and for children 2-18 years euro 118.02 (euro 93.85 in Belgium, euro 121.35 in France, euro 124.54 in Germany and Ł 69.49/euro 79.56 in the UK), of which 63% is attributable to nutrients and 28% to wages. CONCLUSION The data indicated that PN costs differ among countries and a major proportion was due to staff time (Ł 1=euro 1.144959).

Abstract
Zearalenone (ZEA), an estrogenic mycotoxin, is produced mainly by Fusarium fungi. Previous studies indicated that acute ZEA exposure induced oxidative stress and damage in multiple organs. Therefore, the present study was designed to investigate the adverse effects of dietary ZEA (1.1 to 3.2 mg/kg of diet) on oxidative stress and organ damage in postweaning gilts. A total of 20 gilts (Landrace × Yorkshire × Duroc) weaned at d 21 with an average BW of 10.36 ± 1.21 kg was used in the study. Gilts were housed in a temperature-controlled room, divided into 4 treatments, and fed a basal diet only (control) or basal diet supplemented with purified ZEA at a dietary concentration of 1 (ZEA1), 2 (ZEA2), or 3 (ZEA3) mg/kg of diet for 18 d ad libitum. The actual ZEA contents (analyzed) were 0, 1.1 ± 0.02, 2.0 ± 0.01, and 3.2 ± 0.02 mg/kg for control, ZEA1, ZEA2, and ZEA3, respectively. Gilts fed different amounts of dietary ZEA grew similarly with no difference (P > 0.05) in feed intake. Vulva size increased linearly over the 18 d of feeding in gilts fed diets containing 1.1 mg of ZEA/kg or greater (P < 0.001). Relative weight of genital organs, liver, and kidney increased linearly (P < 0.05) in a ZEA-dose-dependent manner. Serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamate transferase, urea, and creatinine (P < 0.05), and malondialdehyde concentrations in both serum and liver (P < 0.001) were also increased linearly in a ZEA-dose-dependent manner. However, spleen relative weight (P = 0.002) and activities of total superoxide dismutase and glutathione peroxidase (in both serum and liver (P < 0.05) were decreased linearly as dietary ZEA increased. Results showed that besides genital organs, the liver, kidney, and spleen may also be target tissues in young gilts fed diets containing 1.1 to 3.2 mg of ZEA/kg for 18 d. Increased key liver enzymes in the serum suggest progressive liver damage caused by feeding ZEA, and an increase in oxidative stress in gilts is another potential impact of ZEA toxicity in pigs.

Abstract
Recent studies have revealed that the prevalence of Wolbachia in arthropods is attributable not only to its vertical transmission, but also to its horizontal transfer. In order to assess the horizontal transmission of Wolbachia between predator and prey, arthropods belonging to 11 spider families and six insect families were collected in the same field of rice. The distribution of Wolbachia in these arthropods was detected by diagnostic PCR amplification of the wsp (Wolbachia outer surface protein gene) and 16S rDNA genes. Nurscia albofasciata Strand (Araneae: Titanoecidae), Propylea japonica Thunberg (Coleoptera: Coccinellidae), Paederus fuscipes Curtis (Coleoptera: Staphylinidae), and Nilaparvata lugens Stal (Homoptera: Delphacidae) were infected with Wolbachia. This is the first report of infection of N. albofasciata and P. fuscipes by Wolbachia. No direct evidence indicated the existence of horizontal transmission of Wolbachia between predator and prey.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease with unknown etiology. Programmed death 1 (PD-1) and its ligands (PD-L1 and PD-L2), B7-H1/PD-L1 and B7-DC/PD-L2, are new CD28-B7 family members that are involved in the regulation of immune responses. Previous observation suggests that PD-1 system plays an inhibitory role in regulating peripheral blood T cells, B cells and myeloid cells, thus their abnormality may be related to autoimmune diseases. This study aimed to explore the role of PD-1/PD-L1, L2 system in the pathogenesis of AIH. METHODS The mice model of experimental autoimmune hepatitis (EAH) was established in C57BL/6 mice and the expression levels of PD-1 and PD-L1, L2 in the murine liver and the cytokines, including interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha and interleukin (IL)-4 in the spleen were detected using reverse transcription-polymerase chain reaction (RT-PCR), and the results were compared with those of normal controls. RESULTS The expression levels of PD-1, PD-L1, PD-L2 mRNA were higher in EAH compared with normal controls (P < 0.05), the PD-L2/PD-1 ratio was relatively lower in EAH (EAH -0.08 +/- 0.35, normal controls 0.52 +/- 0.07, P = 0.009). In the EAH, the expression of the three cytokines were all upregulated compared with normal controls. PD-L1 had a positive correlation with the expression of IFN-gamma (r = 0.289, P < 0.05), while PD-L2 showed a positive correlation with both expressions of IL-4 (r = 0.378, P< 0.01) and IFN-gamma (r = 0.261, P < 0.05). While TNF-alpha showed no correlation with PD-L1 (r = 0.044, P = 0.736) or PD-L2 (r = 0.127, P = 0.335). CONCLUSIONS The expression of PD-1/PD-L1, L2 is upregulated in EAH and regulated by IFN-gamma and IL-4. PD-1 system may play an important role in the pathogenesis of AIH.

Abstract
OBJECTIVE To study the effects of all factors during the process of urea encapsulation of gamma-linolenic acid on the purity and yield. METHOD To observe the material proportions, time, temperature and purity using single-factor and two-factor tests. RESULT Single-factor test showed that the optimal ratio of all materials (oil, urea and 95% ethanol) was 1:3:8. A 30% purity after single encapsulation process was obtained, at the best temperature range was - 15 degrees C-20 degrees C, for 24 hours. Two-factor test showed that the optimal ratio of oil, urea and ethanol was 1:3:8, where the concentration of ethanol was 90%-95%. The purity reached 90% or higher, with three-time encapsulation process. CONCLUSION An optimized process was identified where material ratios, encapsulation time, temperature, and ethanol concentrations were determined using single-factor and two-factor tests.

Abstract
An advanced backcross strategy was used to identify quantitative trait loci (QTLs) associated with plant height and days to heading in the BC3F2 population derived from an accession of common wild rice (Oryza rufipogon Griff.) from Yuanjiang in Yunnan Province of China, as the donor, and an elite Indica cultivar "Teqing", as the recipient. Based on analyses of 116 SSR markers distributed throughout the rice genome and by using single-point analysis, four putative QTLs derived from O. rufipogon were detected for plant height on chromosome 1, and 6 QTLs for days to heading on chromosome 1, 3, 7, 8 and 11. All Alleles of QTLs for plant height from O. rufipogon could increase plant height of the backcross population. One QTL near RM104 on chromosome 1, explaining 27% and 28% of phenotypic variance and additive value reached 26.24 cm and 26.28 cm respectively in Beijing and Hefei, was detected. The location of this QTL is corresponding to sd-1. One QTL near the marker RM25 on chromosome 1, explaining 13% and 15% of phenotypic variance was identified. The additive value of this QTL reached 4.60 days and 3.65 days respectively in Beijing and Hefei, and the allele from O. rufipogon could delay the backcross population's days to heading.

Abstract
OBJECTIVE To summarize the experience of blood transfusion during orthotopic liver transplantation (OLT). METHODS The clinic data and blood transfusion of 28 patients during OLT were analyzed. RESULTS The total blood volume of transfusion was 9 517 +/- 7 680 ml averagely for the 28 patients in general during OLT, including that of an infant (920 ml), massive blood transfusion in 2 cases (28740 ml and 38580 ml respectively). The transfusion volume of patients with anemia or/and thrombcytopenia before the operation was not more than that of patients with normal blood routine. CONCLUSION In general, 5 000 - 10 000 ml is reserved for receptor of OLT before the operation. We should take measures to deal with massive blood transfusion. The preparative blood volume for receptor of OLT can not depend on the result of blood routine.

Abstract
OBJECTIVE To clarify the clinicopathologic significance of immunohistochemistry for proliferative activity and oncoprotein expression in astrocytic tumors. STUDY DESIGN Ninety-seven cases of brain astrocytic tumors with histologic grading and follow-up data were investigated with immunohistochemistry and image analyzer to detect the expression of proliferating cell nuclear antigen (PCNA), silver-binding nucleolar organizer regions (AgNORs) and several oncoproteins. RESULTS PCNA was significantly related to AgNORs, grading and prognosis of astrocytomas. The frequency of mutant p53 protein expression was higher in grade 2-4 astrocytomas than in grade 1. Epidermal growth factor (EGF) (37.1%), EGF receptor (83.5%) and p21ras (42.3%) expression levels were related to neither the grade nor prognosis of the tumors. The positive ratios of p53 antibodies were higher in grades 2-4 than in grade 1, and the intensities correlated with PCNA but not with prognosis. CONCLUSION Aberrations of c-erbB-2, p21ras, EGF and EGF receptor might be early events in the initiation and progression of astrocytomas, whereas p53 overexpression is involved in all the stages. Immunohistochemical detection had no prognostic value. PCNA could be important to the evaluation of astrocytoma malignancy.

STUDY DESIGN Factor VIII-related antigen (FVIII-RAg) was used as the marker of endothelia and basic fibroblast growth factor (bFGF); FGF receptor (FGFR)-1 and vascular endothelial growth factor (VEGF) were qualitatively and quantitatively detected with immunohistochemistry and image analysis in 61 brain astrocytomas. The correlation with tumor grades, angiogenesis and prognosis was studied. RESULTS Measurement of FVIIIRAg expression could describe endothelial proliferation and vascularity, which were related to grade of tumor and prognosis. bFGF and VEGF expression levels in neoplastic astrocytes and endothelia were significantly different in various grades of astrocytoma. These angiogenic factors affected the positive reaction areas and integral optical densities of FVIII-RAg as well as survival time. In contrast, the expression of FGFR-1 was related to neither bFGF nor FVIIIRAg and had no significant effect on tumor malignancy. CONCLUSION Positive regulation by bFGF and autocrine/paracrine VEGF contributes to the growth and angiogenesis of astrocytomas. Measurement of endothelial cell proliferation with FVIIIRAg in tumor stroma and quantitative detection of angiogenic factor levels in neoplastic cells had prognostic value in brain astrocytomas. The results also indicate that inhibiting bFGF and VEGF expression and/or blocking their effects could be a very useful therapeutic strategy for malignant gliomas.

Abstract
A multicentre retrospective study of ulcer-carcinoma was carried out in 16 hospitals in China, with the aim of examining the correlation between pre-cancerous lesions and malignant change associated with benign gastric ulcer. Malignant change occurred at 2% over a variable period of 6 months to 15 years. About two-thirds of the ulcer cancers were found to be tubular adenocarcinoma.

Abstract
Nuclear DNA content was measured by microspectrophotometry in 40 biopsy specimens from patients with large bowel polyps (10 juvenile polyps and inflammatory polyps, 25 adenoma subdivided into 3 groups with 10 Grade I, 10 Grade II and 5 Grade III, 5 cancerous degeneration), and 5 normal epithelium of large intestine. The mean DNA value increased steadily as follows: normal epithelium of intestine (13.54 +/- 1.76 Au); juvenile polyps and inflammatory polyps (14.89 +/- 0.40 Au); adenoma Grade III (21.96 +/- 0.92 Au); cancerous degeneration (24.47 +/- 1.48 Au). The difference in DNA value in these groups was statistically significant (P less than 0.05-0.01). These results suggest that measurement of nuclear DNA content may serve as an objective quantitative parameter for diagnosis of large bowel carcinomatous change of polyps and classification of polypoid adenomas.

Abstract
The method which combines the removable appliance with a headgear attached to the maxillary dentition is widely used in treatment of the maxillary protrusion of growing children. The initial reaction of maxillary complex caused by the removable appliance retraction was studied by the holographic interferometry. In this paper, the results indicate that when the pull applied along the occlusal plane the maxilla was moved downward, whereas when the pall applied along the occlusal plane at 15 the maxilla was moved upward and backward. The advantage of this method and model of the experimentation was discussed in the paper.

Abstract
Nuclear DNA content was measured by microspectrophotometry in 15 biopsy specimens from patients with G-I smooth muscle tumors (3 leiomyomas and 12 leiomyosarcomas subdivided into 3 groups with 4 cases to each). The mean DNA value increased steadily as follows: leiomyomas (14.39 +/- 0.62 Au); leiomyosarcoma Grade I (19.78 +/- 2.39 Au); Leiomyosarcoma Grade II (26.39 +/- 1.60 Au); leiomyosarcoma Grade III (30.66 +/- 2.39 Au). The difference of DNA value in the 4 groups had statistical significance (P less than 0.05-0.01). These results suggest that microspectrophotometric measurement of nuclear DNA content may serve as an objective quantitative method for diagnosis of G-I tract smooth muscle tumors and classification of leiomyosarcoma.
