Abstract
The Chinese Loess Plateau has been the cradle of Chinese civilization and the main human settlement in China for thousands of years, where anthropogenic activities are believed to have deeply eroded natural landscapes. After decades of minimal leopard sighting in forests of northern China, due to serious human interference, we recently discovered that the leopard population is recovering. This finding provides hope for successful biodiversity conservation in human-dominated ecosystems. To understand the mechanism of leopard return into such a highly fragmented landscape, we applied the concept of ecological networks (ENs) to identify key factors promoting leopard restoration and quantify the ecological links among habitats. We first determined the existence of a healthy leopard population in the study area based on the size of its home range and presence of breeding individuals. We then innovatively used the relationship between species richness and top predators to generate ENs, and found that the connectivity of ENs had a significant positive interaction with leopard survival. Our study validates the effectiveness of establishing ecologically connected habitats for leopard protection, and highlights the importance of applying ENs for conservation planning in highly fragmented ecosystems. This study provides a successful case for the protection of top predators in human-dominated landscapes.

Abstract
OBJECTIVE To evaluate the impact of maternal exposure to polycyclic aromatic hydrocarbons (PAHs) and methylation levels of CHDs-candidate genes on the risk of congenital heart diseases (CHDs), and the effect of PAHs exposure on DNA methylation states. METHODS A case-control study involving 60 mother -fetus pairs was performed by measuring 1-OHPG concentration in maternal urine and methylation levels of 20 CHDs-candidate genes in cord bloods. Logistic regression models were applied to determine the effect of maternal PAHs exposure and fetal methylation levels on the risk of CHDs. Spearman correlation was performed to correlate PAHs exposure and methylation levels. RESULTS Maternal higher PAHs exposure was associated with the risk of CHDs (aOR = 3.245, 95% CI: 1.060, 9.937) or some subtypes. The methylation levels of 23 amplicons within 11 genes exhibited significant differences between CHDs and controls. Higher methylation of NKX2-5_M1 was associated with decreased risk of CHDs (aOR=0.182, 95% CI:0.034, 0.983). No significant correlations were found between 1-OHPG concentration and methylation levels of NKX2-5_M1. CONCLUSIONS Maternal PAHs exposure was linked with CHDs. Higher methylation of the upstream sequence of NKX2-5 promoter decreased the risk of CHDs. There was no correlation between maternal PAHs exposure and the methylation level of NKX2-5.

Abstract
Cutaneous T-cell lymphomas (CTCLs) are a group of T-cell lymphomas with low incidence. Due to their indolent characteristics, treatment strategies have not yet been established for advanced CTCLs. In this study, relative incidence of CTCLs in Asia was estimated and the therapeutic outcomes presented based on various treatments currently used in clinics for advanced CTCLs. As part of a prospective registry study of peripheral T-cell lymphoma (PTCL) conducted across Asia, including Korea, China, Taiwan, Singapore, Malaysia, and Indonesia, subgroup analysis was performed for patients with CTCLs. Among 486 patients with PTCL, 37 with CTCL (7.6%) were identified between April 2016 and February 2019. Primary cutaneous ALK-negative anaplastic large cell lymphoma (ALCL, 35.1%) was the most common subtype. With a median follow-up period of 32.1 months, median progression-free survival (PFS) was 53.5 months (95% CI 0.0-122.5), and overall survival was not reached. 14 patients (48.2%) underwent subsequent treatment after the first relapse, but the response rate was 20% with a PFS of 2.2 months (95% CI 0.3-4.0). Six patients received autologous stem cell transplantation (auto-SCT). However, auto-SCT did not result in better outcomes. Additional studies are needed on standard care treatment of advanced or refractory and relapsed CTCLs.

Abstract
An objective understanding of the current situation and influencing factors of rural green development in China is an important prerequisite for effective formulation making of green development policies. Based on the panel data of 31 provinces of China from the year 1997 to 2017, this paper constructs and measures the rural green development efficiency (RGDE) based on Driving-Force, Pressure, State, Influence, Response (DPSIR) model and super-efficiency slacks-based measure (SBM) model. The results show that, the overall RGDE in China is fluctuating and rising from 1997 to 2017, and there are some differences between and within regions. The RGDE in developed areas is higher than that in developing areas, and coastal areas are higher than that in inland areas. The entire country, eastern, central, and western regions show σ convergence, which indicates that the RGDE is getting better, but there is no absolute β convergence, that means there is no "catch-up effect" between regions, but the gradient divergence showed central > eastern > western. At the same time, there is no conditional β convergence; the initial RGDE has a positive impact on the growth rate of RGDE, and the financial self-sufficiency rate promotes the growth of RGDE of the whole country and the western region, but inhibits the improvement of RGDE of the eastern region. The per capita GDP, mechanization degree, and agricultural industrial structure in rural areas did not promote the growth of RGDE. Based on the results, this paper puts forward some policy suggestions, such as promoting the classified implementation of rural green development policies, strengthening the top-level design, optimizing the existing agricultural mechanism and system, and guiding and standardizing the farmers' green production behavior.

Abstract
Phytoextraction has been identified as one of the most propitious methods of phytoremediation. This pot experiment were treated with varying amounts of (ethylenediamine triacetic acid) EDTA 3-15, (Nitriloacetic acid) NTA 3-10, (Ammonium citrate) NH4 citrate 10 - 25 mmol and one mg kg(-1)Cd, filled with 5 kg soil. The addition of chelators significantly increased Cd concentration in soil and plant. The results showed that maximum Cd uptake was noted under root, shoot and leaf of castor plant tissue (2.26, 1.54, and 0.72 mg kg(-1)) under EDTA 15, NTA 10, and NH4 citrate 25 mmol treatments respectively, and in soil 1.08, 1.06 and 0.52 mg kg(-1) pot(-1) under NH4 citrate 25, NTA 10 and EDTA 15 mmol treatments respectively, as against to control (p < 0.05). Additions of chelators reduction biomass under the EDTA 15 mmol as compared to other treatments, However, Bioconcentration factor (BCF), translocation factor (TF) and remediation factor (RF) were significantly increased under EDTA 15 and NH4 citrate 25 mmol as against control. Our results demonstrated that castor plant proved satisfactory for phytoextraction on contaminated soil, and EDTA 15 and NH4 citrate 25 mmol had the affirmative effect on the Cd uptake in the artificial Cd-contaminated soil.

Abstract
BACKGROUND It's unknown whether the prognostic value of admission heart rate (HR) was different in patients with ST-segment elevation myocardial infarction (STEMI) with or without concomitant type 2 diabetes mellitus (T2DM). METHODS Consecutive STEMI patients who presented within 12 hours of symptom onset were recruited from 274 hospitals in China. Participants were stratified into quartiles by admission HR. Baseline characteristics, current therapeutic recommenda- tions, laboratory biochemical tests, 30-day all-cause mortality and Cardiovascular Events (CVE, including all-cause death, reinfarction and stroke) were compared across admission HR quartiles. RESULTS We evaluated 7294 STEMI patients, of these 820 (11.2%) had known T2DM. The admission HR quartile stratification was significantly associated with all-cause mortality and CVE regardless of T2DM status (P < 0.001 both for survival and CVE). After adjusted other risk factors, in patients without T2DM, comparing with HR <66 b.p.m., the increase of HR level was associated with worse prognosis (P < 0.05). In patients with T2DM, the hazard ratios for 30-day CVE were 1.75 (95%CI), 1.92 (95%CI), 3.00 (95%CI) in the HR of 66-76 b.p.m., 77-88 b.p.m., and >88 b.p.m., respectively. Results were similar for 30-day all-cause mortality, but the hazard ratios in Q2 (P = 0.139 and P =0.086 for survival and CVE, respectively) and Q3 groups were non-significant (P = 0.072 and P =0.033 for survival and CVE, respectively). There was a significant interaction effect of HR and T2DM on 30-day CVE mortality (P = 0.035), which was not found on all-cause mortality (P = 0.126). CONCLUSION Admission heart rate was an important risk factor of 30-day all-cause mortality and CVE in patients with STEMI with or without T2DM. However, the predictive effect was modified by T2DM.

Abstract
Hydroxyapatite is the main inorganic component of biological bone and tooth enamel, and synthetic hydroxyapatite has been widely used as biomaterials. In this study, a facile method has been developed for the fabrication of arginine-functionalized and europium-doped hydroxyapatite nanoparticles (Arg-Eu-HAP). The synthesized nanoparticles characterized by transmission electron microscopy, X-ray diffractometry, Fourier transform infrared, and Zeta potential analyzer. Its biological properties with DNA binding, cell toxicity, cell binding and intracellular distribution were tested by agarose gel electrophoresis assay, flow cytometry, and fluorescence microscope and laser scanning confocal microscope. The synthesized Arg-Eu-HAP could effectively bind DNA without any cytotoxicity and be internalized into the cytoplasm and perinuclear of human lung epithelial cells.

Abstract
Municipal wastewater discharge is threatening the ecological security of the local water environment. This study investigated the field process performance and microorganism characteristics of enhanced biological phosphorus removal (EBPR) in municipal wastewater treatment plants (WWTPs) in China. The results showed that three WWTPs met the required criteria of phosphorus for discharge (< or = 1 mg/L), but with a low level of Accumulibacter (6.4 to 3.8%, on average) and a relatively high level of Competibacter (3.2 to 9.1%) in sludge. The phosphorus release and uptake rates were varied from 0.224 to 7.770 mg/gVSS x h and 0.386 to 7.901 mg/gVSSh, respectively. Denitrifying polyphosphate-accumulating organisms were estimated to be 28.2% of the polyphosphate-accumulating organisms. Sludge characteristics (phosphorus release and uptake rates) were positively correlated with the abundance of Accumulibacter and negatively correlated with the proportion of Competibacter. Moreover, the lower the ratio of anaerobic phosphorus/acetate (e.g., 0.496) is, the more abundant the Competibacter would be. Further discussion on an improvement strategy for these WWTPs for EBPR should be comprehensively based on the data of periodic investigations on field operation, sludge activities, and microbial populations.

Abstract
OBJECTIVES The aim of this study was to evaluate the effects of pulse high-volume hemofiltration (PHVHF) in patients with severe sepsis. METHODS Twenty-two patients with severe sepsis admitted to XiJing hospital between January 2009 and January 2010 were included in the present study. Patients were randomly divided into the control group (conventional treatment) and the PHVHF group. Patients in the PHVHF group received 72 h of PHVHF treatment in addition to conventional treatment after admission. PHVHF was conducted as follows: HVHF 85 ml/kg per hour for 6 h followed by continuous venovenous hemofiltration 35 ml/kg per hour for 18 h with an AN69 membrane. The hemofilter was replaced every 24 h and PHVHF was performed with 250 to 300 ml/min blood flow rate. The blood samples were taken to measure the changes of plasma cytokines (TNF-α, IL-1, IL-4, IL-6 and IL-10). RESULTS With 72 h of PHVHF treatment, there was an improvement in clinical features and hemodynamics variables in PHVHF-treated patients. All plasma cytokines after PHVHF treatment were significantly lower than those at the start of PHVHF treatment (p<0.05). In contrast, there was no significant change in control patients. CONCLUSIONS Our findings suggest that PHVHF is a feasible adjuvant modality in the treatment of patients with severe sepsis. With the application of PHVHF treatment, plasma cytokines are effectively removed. Considering the lower cost and better feasibility than continuous high-volume hemofiltration (CHVF), PHVHF shows promising prospects for the future.

Abstract
OBJECTIVE This study examined the differences in neonatal mortality rates between urban and rural areas in China. METHODS AND RESULTS Data were taken from a database collected by the Chinese surveillance network for mortality of children under 5 years of age. The risk ratio of neonatal mortality for rural versus urban areas was between 2.2 and 2.7 for 1996-2006 and it declined to 2.0 in 2005-6. Pneumonia, birth asphyxia and preterm birth or low birth weight were the major contributors to the urban-rural differences in neonatal mortality, together with a relatively high proportion of home delivery and a relatively lower proportion of hospital treatment in rural areas. CONCLUSION The urban-rural differences reflect the gap between the developed and the underdeveloped regions in China at that period. The neonatal mortality rate in China's rural areas could decrease further if continuous efforts are successful to increase the rates of hospital delivery in rural areas.

Abstract
PURPOSE To investigate the impact of total retrieved lymph nodes (tLNs) on staging and survival in patients with pT2b gastric cancer according to the nodal status. METHODS Clinicopathological characteristics and prognostic outcomes of 392 patients with pT2b gastric cancer between 1980 and 2005 were retrospectively investigated based on the nodal status. RESULTS The number of metastatic lymph nodes (mLNs) was highly correlated with the number of tLNs (P<0.001). The overall 5-year and 10-year survival rates were 39.0% (153/392) and 17.9% (70/392), respectively. The survival rates in patients with pN0 cancers did not differ significantly from that in patients with pN1 cancer when the tLNs were 25 or less. However, the survival rate in patients with N0 cancers was significantly greater than that in patients with pN1 cancers when the tLNs were more than 25 (64.3% vs. 36.9%, chi(2)=4.339, P=0.037). Moreover, both 5- and 10-year survival rates differed significantly among patients with pN1, pN2 and pN3 gastric cancer regardless of tLNs. Multivariate analysis revealed that age, tumor focus number, tumor location, and mLN, but not tLNs, were independent prognostic predictors in patients with pT2b gastric cancer. CONCLUSIONS To improve the accuracy of staging, no less than 15 tLNs should be pathologically examined in patients with pN1-3, and 25 tLNs for the patients with N0. More tLNs may not be associated with a better prognosis in pT2b disease because the extent of lymph node dissection is pre-defined for the operation.

Abstract
The purpose of this study is to investigate the efficacy and safety of recombinant erythropoietin-beta in the treatment of anemic patients with multiple myeloma (MM), low-grade non-Hodgkin's lymphoma (NHL), and chronic lymphocytic leukemia (CLL). From December 2005 to November 2006, the patients with MM, low-grade NHL, and CLL were enrolled in this study, male or female, aged > or = 18 years, transfusion-dependant, and receiving anti-neoplasia chemotherapy. Recombinant human erythropoietin-beta was used in this study with the dose initiated at 150 IU/kg, thrice a week, subcutaneously. The total treatment duration was 12 weeks. The primary endpoint of the study is response rate (RR), which is defined as hemoglobin increasing > or = 2 g/dL comparing to baseline level, or returning to normal range, without any transfusion within 6 weeks of evaluation. Fifty out of 82 (64.6%) patients enrolled in this study responded to the treatment and 29 patients had no response. Hypertension (12.2%) is the most common adverse effect; however, all the adverse events were mild, categorized in NCI grade I or II. We conclude that recombinant erythropoietin-beta was effective in the treatment of anemia of the patients with MM, NHL, and CLL, as well as it is well-tolerated.

Abstract
BACKGROUND Acute coronary syndrome continues to have significant long-term morbidity and mortality. This study sought to compare baseline characteristics, practice patterns and clinical outcomes for patients with non-ST elevation acute coronary syndrome from a broad range of low-, middle- and high-income countries. METHODS AND RESULTS We compared the data from a prospective registry of patients with non-ST elevation acute coronary syndrome involving 4615 patients from 65 centers in 8 low and middle income countries (OASIS registry 2) with those obtained from 7987 patients from 95 centers in 6 middle and high income countries (OASIS registry 1). Patients in the OASIS registry 2 were younger, were more often males and smokers, presented later to the hospital after symptom onset and had a lower prevalence of diabetes at admission [with the exception of India, which had the highest age-adjusted prevalence (39.1%)]. There were marked variations in the angiography and intervention rates during the hospital stay, but the uses of proven pharmacological therapies were comparable. The two-year mortality rates adjusted for baseline covariates ranged from 6.9% to 15%. Patients from China had the lowest two-year mortality rate (6.9%) and patients from India had the highest rate (15%). Combining the two registries, the covariate-adjusted rate of death or myocardial infarction did not differ across countries with in-hospital angiographic rates of > or = 50% (17.1%), 25-49% (16.7%) or < 25% (16.5%). However, the covariate-adjusted rates for subsequent myocardial infarction (7.6%, 9.2% and 10.8% respectively, p < 0.0001), refractory angina (21.3%, 27.7% and 35.4% respectively, p < 0.0001) and the composite of death, myocardial infarction or refractory angina (34.9%, 40.7% and 46.8% respectively, p < 0.0001) differed depending on the angiographic rates. CONCLUSIONS Among the participating countries there was a marked heterogeneity in patient characteristics, coronary interventions, resulting in differences in the two-year composite rates of death, myocardial infarction and refractory angina among patients admitted with non-ST elevation acute coronary syndrome.

PURPOSE The purpose of this study was to study the characteristics of fibrous dysplasia (FD) of bone on bone scans and to evaluate the diagnostic value of radionuclide bone scans in FD. METHODS Radionuclide bone scans were performed in 42 cases of histopathologically proven FD and the results were compared with other imaging modalities. A retrospective study method was used to analyze the imaging results. RESULTS Although FD showed nonspecific increased 99m-Tc MDP uptake, its appearance is different than bone metastates and other bone diseases. Combining scans with x-rays and other imaging modalities can improve the diagnostic accuracy of this disease. CONCLUSIONS Radionuclide bone scans are of certain value in the diagnosis of FD. The diagnostic specificity of FD with radionuclide bone scanning can be improved in association with other imaging modalities such as x-rays.

Abstract
PURPOSE To assess the outcome and complications after combined pars plana vitrectomy and phacoemulsification with intraocular lens implantation in patients with concomitant cataract and vitreoretinal abnormalities. METHODS This retrospective study consisted of 113 eyes of 109 patients with various vitreoretinal abnormalities and visually significant cataract. Vitreoretinal surgery was combined with clear corneal phacoemulsification and intraocular mplantation. RESULTS The combined surgery resulted in minimal complications, and postoperative visual acuity was improved in 83 eyes (71.6%). Visual acuity was improved by two or more lines in 26 eyes (66.6%) with proliferative diabetic retinopathy, 22 eyes (73%) with proliferative vitreoretinopathy, eight eyes (30.7%) with macular abnormalities, four eyes (55.5%) with trauma and two eyes (40%) with retinal vein occlusion. CONCLUSIONS The combined vitreoretinal surgery and phacoemulsification with intraocular lens implantation was safe and effective in treating vitreoretinal abnormalities coexisting with cataract. Combined surgery is recommended for all patients having simultaneous vitreoretinal pathological changes and cataract. The addition of phacoemulsification does not prolong vitreoretinal operative time notably nor increase the risk of intraoperative and postoperative complications significantly

Abstract
In this paper, the influences of overlying tissue and detecting distance between the source and the detector on the measurement of a tissue oximeter were discussed. The signal-noise-ratio of the detector was also examined. A semi-infinite multi-layer Monte Carlo model was induced to simulate the migration of the photons in the skin, adipose and muscle. The thickness of the adipose layer and the separation between the source and the detector in the muscle were changed to simulate the clinical application. Partial pathlength was introduced as a characteristic parameter to evaluate the sensitivity of the oximeter. A two-wavelength (700 and 830 nm) tissue oximeter was developed to verify the results of the simulation. The Monte Carlo simulation results showed that the sensitivity of the near infrared spectroscopy (NIRS) oximeter declined greatly with increasing overlying tissue thickness. Increasing the distance between the light source and the detector improved the sensitivity. However, in order to achieve a sufficiently high signal-to-noise ratio, it was necessary to limit this distance. The results of a bicycle ergometer exercise verified the above results and showed that, for a special adipose thickness (AT), there may be a reasonable range of the emitter-detector separation.

Abstract
BACKGROUND Apoptosis is an important mechanism by which neutrophils are removed from sites of inflammation, including the kidney. This study investigated whether ligation of the cell-surface adhesion molecule, CD44, can trigger neutrophil apoptosis. METHODS The anti-rat CD44 antibody OX-50 was used to induce apoptosis of cultured blood neutrophils, as determined by flow cytometry using annexin V staining and by transmission electron microscopy. The functional consequences of OX-50-mediated neutrophil depletion were examined in a rat model of accelerated antiglomerular basement membrane glomerulonephritis. RESULTS Flow cytometric analysis using the OX-50 antibody, which recognizes the common amino terminal domain of CD44, showed that rat blood neutrophils express very high levels of CD44. The addition of OX-50, but not control antibodies, rapidly induced neutrophil apoptosis in cultured rat blood leukocytes, as demonstrated by annexin V staining and by electron microscopy. Cross-linking of CD44 was essential since F(ab) fragments of the OX-50 antibody failed to induce neutrophil apoptosis. The CD44 ligand hyaluronan and an antibody to the CD44v6 isoform failed to induce neutrophil apoptosis, indicating that OX-50 antibody-mediated neutrophil apoptosis is epitope specific. This effect was specific to neutrophils since the OX-50 antibody did not induce apoptosis in other CD44-expressing cell types (lymphocytes, mesangial cells, or tubular epithelial cells). An injection of OX-50 antibody into normal rats caused a rapid and profound neutropenia, and apoptotic neutrophils could be seen in the blood by electron microscopy. Furthermore, the administration of OX-50 antibody abrogated neutrophil-dependent glomerular injury (proteinuria) on day 1 of rat antiglomerular basement membrane glomerulonephritis, whereas injury on day 10 of the disease (neutrophil independent) was largely unaffected. CONCLUSIONS The cross-linking of specific epitopes of the CD44 molecule can rapidly induce neutrophil apoptosis in vitro and inhibit neutrophil-dependent renal injury in vivo. This finding suggests that physiological ligands of the CD44 molecule may play an important role in eliminating neutrophils from sites of inflammation, including inflammatory kidney disease.

Abstract
In this double-blind, placebo-controlled crossover study, we examined the effect of transdermal clonidine (given for 5 days) on autonomic control in 14 patients with mild to moderate congestive heart failure by heart rate variability analysis. Compared with placebo, clonidine increased the 24-h mean R-R interval from 718+/-110 to 811+/-117 ms (P<0.01), increased the S.D. of all normal RR intervals (SDNN) from 60.8+/-18.5 to 80.9+/-21.4 ms (P<0.01), the S.D. of the average RR intervals for all 5-min segments (SDANN) from 54.7+/-15.2 to 70.5+/-18.4 ms (P<0.01) and the mean of the S.D.s of all RR intervals for all 5-min segments (SDNN index) from 29.2+/-8.3 to 36.5+/-8.1 ms (P<0.01). The root mean square successive differences (r-MSSD) and the percent of differences between adjacent RR intervals >50 ms (pNN50) were also increased from 18.3+/-6.7 to 23.1+/-7.0 ms (P<0.01) and from 2.1+/-1.9 to 4.5+/-3.0% (P<0.01). In addition, total power, low frequency power and high frequency power were increased from 641+/-322 to 898+/-403 ms2/Hz (P<0.01), from 149+/-97 to 216+/-133 ms2/Hz (P<0.01) and from 52.8+/-27.1 to 93.2+/-41.3 ms2/Hz (P<0.01), respectively. The plasma norepinephrine level was decreased significantly from 0.52+/-0.18 to 0.24+/-0.09 ng/ml (P<0.01) after clonidine therapy. Changes in heart rate variability measures after clonidine administration were positively related to changes in plasma norepinephrine level. These results indicate that suppressing the sympathetic nervous system by clonidine improves autonomic balance in patients with congestive heart failure. But whether such restoration of the autonomic control has a beneficial effect on the long-term management of these patients still needs further investigation.

Abstract
CD44 is a widely expressed cell surface glycoprotein which is involved in both cell-matrix and cell-cell interactions which regulate a variety of processes, including leucocyte migration and activation. Therefore, we examined the expression of CD44, and its major ligand hyaluronan, during the induction and progression of experimental glomerulonephritis. Antibody staining of normal rat kidney showed constitutive CD44 expression by resident glomerular macrophages, parietal epithelial cells, medullary and occasional cortical tubules. There was a marked increase in CD44 expression over days 1, 7 and 21 of rat crescentic anti-glomerular basement membrane (GBM) glomerulonephritis. Infiltrating monocytes and lymphocytes were CD44+, with ultrastructural studies showing high levels of CD44 expressed on the surface of lymphocytes adherent to activated endothelium. Marked hyaluronan deposition was seen in areas of fibrosis on days 7 and 21, such as glomerular crescents and the periglomerular area. Hyaluronan deposition was accompanied by the presence of many CD44+ cells. Double immunohistochemistry showed that both CD44+ED1+ macrophages and CD44+ myofibroblasts (identified by expression of alpha-smooth muscle actin) were present in areas of fibrosis. There was also a dramatic increase in cortical tubular CD44 expression, which was most evident in areas of tubular damage. Although tubular epithelial cells expressed CD44 upon both the basolateral and luminal surface, CD44 expression was most prominent within tightjunctions, suggesting a role for CD44-CD44 interactions in cell-cell adhesion within the tubule. Analysis of CD44 isoforms by reverse transcriptase-polymerase chain reaction (RT-PCR) showed that the standard form of CD44 predominated in both normal and diseased kidney. However, a series of alternatively spliced CD44 isoforms was also detected, whose expression was markedly increased during disease. At least seven isoforms containing the v6 domain were identified, with the smallest form representing activated T cells. In conclusion, CD44 is constitutively expressed in normal kidney and is dramatically up-regulated in rat anti-GBM disease, suggesting possible roles for the CD44-hyaluronan interaction in leucocyte recruitment, renal fibrosis and tubular cell-matrix and cell-cell interactions during the induction and progression of crescentic glomerulonephritis.

Abstract
CD44 is the major cell-surface receptor for hyaluronan, and cell-matrix interactions mediated by the CD44/hyaluronan receptor-ligand pair are involved in a variety of cellular functions, including cell migration. The aim of the study presented here was to examine the expression of CD44 and hyaluronan in the mesangial proliferative response in rat anti-Thy-1 nephritis. In normal rat kidney, CD44 is expressed by medullary tubules, some distal tubules and thick ascending limbs of Henle, dendritic-like cells around Bowman's capsule, and some interstitial cells. However, only occasional CD44+ cells were found within the glomerular tuft. In experimental nephritis, there was an early glomerular influx of CD44+ macrophages, which peaked on Day 4 after anti-Thy-1 antibody injection. A striking finding was de novo CD44 expression by mesangial cells. This CD44 expression was restricted to the transient period of mesangial cell proliferation as shown by double-staining with an antibody against the proliferating cell nuclear antigen. Immunohistochemistry staining also demonstrated hyaluronan deposition within segmental areas of proliferating CD44+ cells, suggesting a functional interaction between the CD44/hyaluronan receptor-ligand pair during mesangial cell proliferation. In vitro, rat mesangial cells were shown to express mRNA and protein for the 90-kd isoform of CD44. In addition, hyaluronan-dependent aggregation of CD44+ mesangial cells was specifically inhibited by an anti-CD44 antibody, demonstrating a functional interaction between hyaluronan and the CD44 expressed on the surface of rat mesangial cells. In conclusion, these data suggest that cell-matrix interactions mediated by the CD44/hyaluronan receptor-ligand pair are involved in mesangial cell proliferation in rat anti-Thy-1 nephritis.
