Abstract
Climate dictates wildfire activity around the world. But East and Southeast Asia are an apparent exception as fire-activity variation there is unrelated to climatic variables. In subtropical China, fire activity decreased by 80% between 2003 and 2020 amid increased fire risks globally. Here, we assessed the fire regime, vegetation structure, fuel flammability and their interactions across subtropical Hubei, China. We show that tree basal area (TBA) and fuel flammability explained 60% of fire-frequency variance. Fire frequency and fuel flammability, in turn, explained 90% of TBA variance. These results reveal a novel system of scrubland-forest stabilized by vegetation-fire feedbacks. Frequent fires promote the persistence of derelict scrubland through positive vegetation-fire feedbacks; in forest, vegetation-fire feedbacks are negative and suppress fire. Thus, we attribute the decrease in wildfire activity to reforestation programs that concurrently increase forest coverage and foster negative vegetation-fire feedbacks that suppress wildfire.

Abstract
Lipopolysaccharide (LPS), a core part of gram-negative bacteria, is crucial for inducing an inflammatory response in living things. In the current study, we used LPS from Salmonella to stimulate chicken macrophages (HD11). Proteomics was used to investigate immune-related proteins and their roles further. Proteomics investigation revealed 31 differential expression proteins (DEPs) after 4 hours of LPS infection. 24 DEPs expressions were up-regulated, while seven were down-regulated. In this investigation, ten DEPs were mainly enriched in S. aureus infection, complement, and coagulation cascades, which were all implicated in the inflammatory response and clearance of foreign pathogens. Notably, complement C3 was shown to be up-regulated in all immune-related pathways, indicating that it is a potential protein in this study. This work contributes to a better understanding and clarification of the processes of Salmonella infection in chickens. It might bring up new possibilities for treating and breeding Salmonella-infected chickens.

Abstract
PURPOSE Erectile dysfunction and COVID-19 share similar risk factors, including vascular disruption of integrity, cytokine release, cardiovascular disease, diabetes and obesity. The aim of this study was to investigate the association between erectile dysfunction and COVID-19 patients. METHODS Odds ratio for erectile dysfunction in patients with a history of COVID-19 with and without comorbidities were calculated using a patients' registry platform i2b2. ICD-10 diagnoses codes were accessed for queries and data were analyzed using logistic regression. RESULTS Patients with COVID-19 were 3.3 times more likely to have erectile dysfunction with 95% CI (2.8, 3.8). The association became stronger with odds ratio 4.8 (95% CI (4.1, 5.7)) after adjusting for age groups. The odds ratio remained the same after adjusting for smoking status with 3.5 (95% CI (3.0, 4.1)). After adjusting for race, COVID-19 patients were 2.6 (95% CI (2.2, 3.1)) times more likely to have erectile dysfunction. The odds ratio were 1.6, 1.8, 1.9 and 2.3 after adjusting for respiratory disease, obesity, circulatory disease and diabetes, respectively. CONCLUSION COVID-19 and erectile dysfunction are strongly associated even after adjustment for known risk factors and demographics.

Abstract
OBJECTIVE To screen differentially expressed proteins (DSPs) in the liver tissues of patients with nonalcoholic steatohepatitis (NASH) using proteomic technologies to identify potential therapeutic targets of NASH. METHODS Liver tissue specimens were obtained from 3 patients with pathologically confirmed NASH and 3 normal control subjects. The total proteins were extracted from the specimens, and iTRAQ reagent was used to label the peptides for liquid chromatography tandem mass spectrometry (LC-MS/MS) detection. The DSPs were identified by comparing the data against UniProt protein database using Mascot2.3.02 software and were annotated and enriched using GO database; KEGG database was used for enrichment of the pathways involving these proteins. Real-time fluorescent quantitative PCR (qPCR) was performed to detect the mRNA expressions of the significant DSPs in NASH. RESULTS By the criteria that a DSP has >1.2 or < 0.8 fold difference between NASH group and the control group and with P < 0.05 as the threshold, a total of 648 significant DSPs in NASH were identified, including 246 up-regulated and 402 down-regulated proteins. GO functional enrichment analysis showed that the DSPs were involved mainly in small molecule metabolism, organic acid metabolism, oxygen acid metabolism and other biological processes, and were enriched in KEGG pathways including the metabolic pathways, complement coagulation cascades, and ribosomes. Among the 25 DEPs with a fold difference >2.0 or < 0.5 (P < 0.05), 6 proteins showed consistent results between qPCR verification and proteomic analysis, including 5 down-regulated proteins: Jumonji protein (JARID2), Lebasillinlike protein (LCA5L), synaptophysin 1 (SYN1) and collagen α-1 (XIII) chain (COL13A1), FYVE, RhoGEF and PH domain protein 5 (FGD5), and 1 upregulated protein glutathione S-transferase Mu 4 (GSTM4). CONCLUSION We identified 648 DEPs inthe liver tissue of patients NASH using iTRAQ technology and bioinformatics methods, and among them JARID2, SYN1, COL13A1, FGD5, and GSTM4 may serve as the key target proteins of NASH.

Abstract
OBJECTIVE To investigate the relationship between electrocardiographic changes and erythropoietin (EPO) level in stable coronary artery disease (CAD) patients with autonomic nerve functional damage. PATIENTS AND METHODS Clinical data of 96 stable CAD patients who were treated in our hospital from January 2017 to December 2019 were retrospectively analyzed. All patients were grouped according to whether autonomic nerve function damage was combined; the baseline characteristic data and the morphological characteristics of ECG scattergram were compared between 2 groups, and the relationship between ECG scattergram and EPO level & autonomic nerve function was analyzed. RESULTS The levels of EPO and red cell volume distributing width (RDW) in stable CAD patients with autonomic nerve dysfunction were significantly higher than that of CAD patients without autonomic nerve dysfunction (p<0.05). The length of scattergram in stable CAD patients with autonomic nerve dysfunction was significantly shorter than that of those without autonomic nerve dysfunction (p<0.05). The cometary sign proportion of ECG scattergram in stable CAD patients with autonomic nerve dysfunction was significantly lower than that of stable CAD patients without autonomic nerve dysfunction (p<0.05). There was negative correlation between EPO levels and scattergram length in stable CAD patients with and without autonomic nerve dysfunction (r=0.44, p=0.02). There was no correlation between EPO levels and scatter width in stable CAD patients with and without autonomic nerve dysfunction (r=0.10, p=0.58). The results of binary logistic regression analysis showed that EPO level was the independent risk factor for the occurrence of autonomic dysfunction in patients with stable CAD (p<0.05). The length of scattergram was the independent protective factor of autonomic nerve function impairment in patients with stable CAD (p<0.05). The AUC of EPO level and scattergram was 0.74 and 0.72 respectively, both of which have similar prediction value. CONCLUSIONS The level of EPO in stable CAD patients with autonomic nerve dysfunction was related to the change of ECG; and the EPO level and scattergram length can be used to predict the occurrence risk of autonomic nerve dysfunction.

Abstract
Abstract
Background
Statins remain a standard treatment for acute coronary syndrome (ACS) patients. We aimed to determine the association between different dosages of in-hospital statins and the prognoses among patients receiving percutaneous coronary intervention (PCI).
Methods
NSTE-ACS patients were retrospectively enrolled from January 2010 to December 2014 from five centres in China. Patients receiving either atorvastatin or rosuvastatin during their hospitalizations were included. All the patients were categorized into high-dose statin group (40mg atorvastatin or 20mg rosuvastatin) or low-dose statin group (20mg atorvastatin or 10mg rosuvastatin). In-hospital events and long-term all-cause death was recorded.
Results
Of the 7,008 patients included in the study, 5,248 received low-dose intensive statin (mean age: 64.28±10.39; female: 25.2%), and 1,760 received high-dose intensive statin (mean age: 63.68±10.59; female: 23.1%). There was no significant difference in in-hospital all-cause death between the two groups (adjusted OR, 1.27; P=0.665). All-cause death was similar between the two groups during the long-term follow-up period (30-day: adjusted HR, 1.28; P=0.571; 3-year: adjusted HR, 0.83; P=0.082). However, there was a robust association between the high-dose statin and the reduction in in-hospital dialysis (adjusted OR, 0.11; P=0.030).
Conclusions
The in-hospital high-dose intensive statin is not associated with lower risks of in-hospital or follow-up all-cause death in NSTE-ACS patients undergoing PCI. Considering the robust beneficial effect of in-hospital dialysis, an individualized high-dose intensive statin can be rational in specified populations.

Abstract
Casestudy
Epstein-Barr virus (EBV)-associated peripheral T-cell lymphomas are a group of aggressive neoplasms with a geographic predilection for South America and Asia, but are very rare in Western populations.
Results
We report a case of a 74-year-old Caucasian female who presented with pancytopenia and B symptoms with EBV-IgG detected on admission. Past medical history included: ITP, chronic urticaria, and recently diagnosed myelodysplastic syndrome (MDS) on bone marrow biopsy one month prior to admission. Excisional biopsies of an enlarged right neck lymph node (repeated within 6 months) and right axillary lymph node five years ago were negative for a lymphoproliferative disorder at the time. Repeated bone marrow biopsy, performed during the current admission, confirmed the diagnosis of MDS, with scattered T-cells without aberrant immunophenotype. Despite aggressive treatment from multiple specialties, the patient deteriorated and expired four weeks later from complications of MDS. At autopsy, there was diffuse lymphadenopathy involving the mediastinum, axilla, pelvis and peripancreatic fat. Lymph node sections demonstrated nodal architecture effacement by diffuse, vaguely nodular lymphoid infiltrates.
Histologically, the infiltrates were composed of medium to large lymphocytes with round to slight irregular nuclei, rare Reed-Sternberg-like multinucleated cells, clumped chromatin, and indistinct nucleoli. Individual cell necrosis was abundant with mitotic figures readily identifiable. Immunohistochemistry revealed CD2+ CD3+ neoplastic T-cells that co-express MUM1 and a subset of CD30, while negative for CD4, CD5, CD8, CD56, ALK1, and TDT. EBV-encoded RNA in-situ hybridization was focally positive. The final postmortem diagnosis was peripheral T-cell lymphoma, not otherwise specified (NOS), with focal EBV positivity.
Conclusion
Co-existence of a de-novo MDS and non-Hodgkin lymphoma without any prior chemotherapeutic exposure is a highly unusual finding, although MDS-like presentations can occur with EBV-associated lymphomas. Peripheral T-cell lymphoma, NOS is an aggressive lymphoma and EBV positivity has been found correlated with a poor prognosis. This case demonstrates how postmortem examination remains an important tool in clinical- pathological correlation and highlights the potential pathogenetic role EBV plays in MDS and T-cell lymphoma.

Abstract
BACKGROUND Previously published data on the association between the XRCC1 Arg194Trp polymorphism and thyroid cancer (TC) remain controversial. METHODS To clarify the association between the XRCC1 Arg194Trp polymorphism and susceptibility to TC, a meta-analysis of case-control studies was conducted. We systematically searched PubMed and CNKI to identify relevant studies. Pooled odds ratios (ORs) of various genetic models were estimated using fixed and random effects models. Heterogeneity was detected by Q-statistic, and the Egger's test was used to evaluate the publication bias. RESULTS A total of seven eligible studies for the XRCC1 Arg194Trp polymorphism (1500 patients and 2358 controls) were included in this meta-analysis. The results of our study failed to suggest an association between the Arg194Trp polymorphism and susceptibility of TC. However, in the subgroup analyses by ethnicity, the OR was 0.82 (C allele vs. T allele, 95% CI 0.68-0.98; P = 0.24 for heterogeneity) among the Chinese population. Nevertheless, no significant differences were observed in the Caucasian population in any genetic model. CONCLUSION This study suggested that the C allele of XRCC1 had an 18% significantly decreased risk of TC in Chinese, and there were no significant associations among Caucasians under all genetic models.

Abstract
1. This study determined the effects of (E)-3-(2-(4-(3-(2,4-dimethoxyphenyl)acryloyl)phenoxy)ethoxy)-5,7-dimethoxy-2-(3,4,5-trimethoxyphenyl)-4H-chromen-4-one (EDACO) on the differentiation of Gaoyou duck embryonic osteoclasts cultured in vitro. 2. Bone marrow mononuclear cells (BM-MNC) were collected from 23-d-old Gaoyou duck embryos and induced by macrophage colony-stimulating factor and receptor activator of nuclear factor κB ligand in the presence of EDACO at different concentrations (i.e. 10, 20, 40, 80 and 160 µM). Tartrate-resistant acid phosphatase (TRAP) staining and resorption ability determination were conducted. 3. Results suggested that EDACO suppressed the shaping of positive multinucleated cells and the number of TRAP-positive cells in the 20, 40, 80 and 160 μM EDACO groups was significantly decreased (P < 0.05 or P < 0.01). Besides, the absorption activity of differentiated duck embryonic osteoclasts was significantly inhibited (P < 0.05) in both 80 and 160 μM EDACO groups. 4. Overall, EDACO can inhibit the differentiation of BM-MNC into mature osteoclasts in duck embryos.1.

Abstract
Objective: To analyze the clinical characteristics of IgG4-related disease (IgG4-RD)so as to improve the understanding of IgG4-RD in China. Methods: IgG4-RD patients were recruited from Peking Union Medical College Hospital between January 2011 and January 2016. All patients were followed-up for more than 6 months. The demographic characteristics, symptoms, organ involvements, laboratory examinations and treatment efficacy were evaluated and analyzed. Results: A total of 346 patients were finally enrolled, including 230 males (66.5%) and 116 females (33.5%). The mean age of disease onset was (53.8±14.2) years old. The mostly common involved organs were lymph nodes (56.4%) and submandibular glands (52.6%). Other affected organs and manifestations included: swelling of the lacrimal glands (46.5%), autoimmune pancreatitis (38.4%), pulmonary involvement (28.0%), sclerosing cholangitis (25.4%), naso-sinusitis (23.4%), parotid gland swelling (21.7%), retroperitoneal fibrosis (19.9%), large arteries involvement (9.5%), kidney involvement (obstructive nephropathy caused by retroperitoneal fibrosis was excluded) (6.9%), skin lesions (6.4%). Rare features consisted of thyroid glands, pituitary glands, gastrointestinal tract, pachymeningitis, pericardium, sclerosing mediastinitis and orchitis. The majority of patients had multi-organ involvement, such as 74.3% patients with 3 and more, 18.2% and 7.5% patients with 2 and single organ involvement respectively. The average IgG4-RD responder index (IgG4-RD RI) was 13.21±5.70. History of allergy was found in 172 (49.7%) patients. As to the laboratory tests, elevated serum IgG4 levels were confirmed in 285 (94.1%) patients, which was positively correlated with IgG4-RD RI. There were 33.5% patients receiving monotherapy of glucocorticoid, 52.6% treated with glucocorticoids combined with immunosuppressive agents, 4.9% patients with immunosuppressant only, and 9.0% patients with mild disease not receiving medication. The majority (336, 97.1%) patients improved the above regimens. Conclusion: IgG4-RD is a systemic fibro-inflammatory disease with multiple organ involvement. The mostly common involved organs include lymph node, submandibular glands, and pancreas. Glucocorticoids and immunosuppressive agents were effective for IgG4-RD.

Abstract
PURPOSE The aim of this study was to determine the effects of different menopausal hormone therapy regimens on body composition in healthy postmenopausal Chinese women. MATERIALS AND METHODS One hundred and twenty-three healthy postmenopausal Chinese women were randomly assigned to either group A (0.625 mg conjugated equine estrogens [CEE] plus 100 mg micronized progesterone [MP]), group B (0.3 mg CEE plus 100 mg MP), or group C (0.625 mg CEE plus 10 mg dydrogesterone). Body composition was assessed by dual-energy X-ray absorptiometry. RESULTS One hundred and two women completed the trial at 1 year. A small but significant gain in lean body mass (619 ± 1019 g, p = 0.002) and a decrease of fat mass in all separate regions was observed in group A. A significant shift from gynoid to android fat distribution was observed in group B and group C (android/gynoid fat percentage ratios increased by 0.06 ± 0.08, p = 0.000 and 0.03 ± 0.08, p = 0.018, respectively), whereas no significant change was observed in group A (0.02 ± 0.06, p = 0.103). CONCLUSIONS In healthy postmenopausal Chinese women, 0.625 mg of CEE combined with 100 mg of MP was associated with a more favorable fat distribution compared with 0.3 mg CEE plus 100 mg MP or 0.625 mg CEE plus 10 mg dydrogesterone.

Abstract
The seed oil of 138 accessions of 14 Acer truncatum (Aceraceae family) populations native to China were analyzed by pulsed nuclear magnetic resonance spectroscopy and gas chromatography-flame ionization detection. The oil content ranged from 17.81% to 36.56% (mean: 28.57%), which mainly consisted of 14 types of fatty acids. Palmitic (4.69%), stearic (2.30%), oleic (25.19%), linoleic (32.97%), linolenic (2.76%), cis-11-eicosenoic (7.90%), erucic (16.49%), and nervonic (5.76%) fatty acids accounted for 98% of total fat. The nervonic acid content ranged from 3.90% to 7.85% among the accessions. Significant variations in oil content and predominating fatty acids were observed among populations. Hierarchical cluster analysis and principal component analysis detected obvious geographical variation trends among A. truncatum populations which correlate with environmental variations (especially altitude, temperature, and precipitation) and supported the grouping of the populations into three groups according to geographic locations.

Abstract
Objective: Using a questionnaire to evaluate different regimens of chemotherapy on ovarian function and quality of life of patients with gestational trophoblastic neoplasia (GTN) . Methods: At least 6 months after completion of chemotherapy, 200 patients with GTN treated in Peking Union Medical College Hospital from January 2010 to June 2017 were randomly selected to fill up the questionnaire. The questionnaire items were included the patient's menstrual cycles, sexual life, gestational issues and common health. The patients were divided into 3 groups by chemotherapy regimens: actinomycin D (Act-D) group, floxuridine+Act-D+vincristine (FAV) or floxuridine+Act-D+etoposide+vincristine (FAEV) group (FAV-FAEV group) , and etoposide+methotrexate+Act-D (EMA) /vincristine+cyclophosphamide (CO) or EMA/ etoposide+cisplatin (EP) group (EMA/CO-EMA/EP group) . Chi-square test was used with a significance level of P-value less than 0.05. Results: One hundred and seventy-three (86.5%,173/200) of the patients completed the questionnaire. Forty three point two percent (43.2%, 19/44) in the EMA/CO-EMA/EP group had a normal menstrual cycle, which were significantly lower than those of Act-D group (84.6%,22/26) and FAV-FAEV group (71.2%, 37/52; all P<0.05) . Amenorrhea rate was also significantly higher in EMA/CO-EMA/EP group (25.0%, 11/44) than in Act-D group (0) and FAV-FAEV group (17.3%, 9/52; all P<0.05) . The sexual life parameters were comparable among 3 groups. Ten out of thirty-two patients conceived after chemotherapy, 2 had miscarriages and 8 had full-term delivery of healthy babies. The common health and labor capacity were significantly decreased after chemotherapy (all P<0.05) . Conclusions: EMA/CO or EMA/EP regimen have a worse impact on ovarian function than Act-D and FAV or FAEV regimen. Gynecologic oncologist should be concerned about the ovarian function and quality of life of GTN patients.

Abstract
OBJECTIVE To evaluate the prevalence of breast tenderness in a population treated with menopausal hormone therapy (MHT) or Cimicifuga foetida extract. METHODS A prospective, randomized, controlled trial was conducted. Ninety-six postmenopausal women were randomly assigned to three groups: group A, 1 mg estradiol valerate daily plus 4 mg medroxyprogesterone acetate (MPA), days 19-30; group B, 1 mg estradiol valerate daily plus 100 mg micronized progesterone (MP), days 19-30; group C, 100 mg C. foetida extract daily. Breast tenderness was evaluated daily for 12 months. RESULTS Seventy-three patients completed the study. Group A had the highest prevalence of breast tenderness, while group C had the lowest. More than 50% of all participants reported no symptoms throughout the period. The participants in group A experienced a sharp increase in breast tenderness after treatment, but decreased after 1 month. No significant decline was found in the duration of pain in group B. The patients in group C reported no remarkable changes after 1 month. Compared to estrogen only, estrogen plus MPA/MP led to a higher incidence of prolonged breast symptoms. CONCLUSIONS Compared to MHT groups, C. foetida extract had the lowest prevalence of breast tenderness. Most participants experienced mild or no symptoms.

Abstract
Objective: To investigate the efficacy and drug related adverse reactions of sorafenib and sunitinib as first-line tyrosine-kinase inhibitors (TKIs) for patients with metastatic renal cell carcinoma (mRCC) and analyze the clinical prognostic factor for survival. Methods: The data of 271 patients with metastatic renal cell carcinoma who had complete clinicopathological data were retrospectively analyzed, including 174 cases in sorafenib group and 97 cases in sunitinib group, to access patients' overall survival (OS) and progression-free survival (PFS). Prognostic values of all characteristics were determined by using univariate and multivariate Cox regression models. Results: The objective response rates (ORR) of the sorafenib and sunitinib groups were 14.9% and 19.6%, respectively, and the disease control rates (DCR) were 85.1% and 88.6%, respectively. No significant difference was found between the sorafenib and sunitinib group in ORR (P=0.325) or DCR (P=0.408). The most common grade 3 to 4 adverse events in the sorafenib group were hand-foot syndrome (6.7%), diarrhea (2.3%), and rash (2.3%). The most common grade 3 to 4 adverse events in the sunitinib group were neutropenia (6.2%), hand-foot syndrome (6.2%), and thrombocytopenia (4.6%). During the follow-up, 97 cases death occurred and 81 cases disease progression occurred in sorafenib group. The median PFS was 12 months (95% CI: 9-15 months), and the median OS was 25 months (95% CI: 21-29 months) in sorafenib group. While 74 cases death occurred and 40 cases disease progression occurred in sunitinib group, the median PFS was 12 months (95% CI: 10-12 months) and the median OS was 23 months (95% CI: 20-32 months) in sunitinib group. No significant difference was found between the sorafenib and the sunitinib group in PFS (P=0.771) or OS (P=0.548). Multivariate analysis showed Fuhrman grades (HR=1.358, 95%CI: 1.004-1.835), number of metastatic sites (HR=1.550, 95%CI: 1.143-2.101) and MSKCC risk grade (Intermediate risk group: HR=1.621, 95%CI: 1.117-2.232; Poor risk group: HR=2.890, 95%CI: 1.942-4.298) were independent prognostic factors for PFS. Fuhrman grades (HR=2.135, 95%CI: 1.533-2.974), number of metastatic sites (HR=1.774, 95%CI: 1.279-2.461) and MSKCC risk grade (Intermediate risk group: HR=1.415, 95%CI: 1.002-1.998; Poor risk group: HR=3.161, 95%CI: 2.065-4.838) were independent prognostic factors for OS. Conclusions: The results of this study indicate that sorafenib and sunitinib are both effective as the first-line TKIs for mRCC patients and sorafenib has comparable efficacy to sunitinib. But they have differences in the incidence of adverse effects. Fuhrman grades, number of metastatic sites and MSKCC risk grade are independent prognostic factors for mRCC patients.

Abstract
Objective: To explore the effect of low-dose or standard-dose conjugated equine estrogen (CEE) combined with natural progesterone or dydrogesterone on bone density in menopause syndrome women. Methods: Totally 123 patients with menopause syndrome were recruited and randomly assigned to 3 treatment groups: group A (low-dose CEE+progesterone) , group B (standard-dose CEE+progesterone) , group C (standard-dose CEE+dydrogesterone) . Using continuous sequential regimen, the duration of intervention was 12 cycles. The bone mineral density of lumbar 2-4 and neck of femur, the bone metabolic markers, the level of FSH and estradiol were examined just before the drug administration and 12 months after the beginning of experiment. Results: There were 107 cases completed the one year trial. (1) Bone density: after 12 cycles of treatment, there was no significant change in bone density in group A (P>0.05) ; lumbar vertebrae of group B and C increased significantly, at 3.0% and 2.1%respectively (all P<0.05) . The bone density of left femoral neck of group C significantly increased by 2.9% (P=0.029) . There was no significant difference among the treatment groups at the beginning of experiment (P>0.05) . (2) Bone metabolic markers: after 12 cycles of treatment, the levels of calcium, phosphorus, alkaline phosphatase, Ca/Cr decreased significantly, the difference were statistically significant (all P<0.05) . There was no significant difference among the treatment groups at the beginning of experiment (P>0.05) . (3) Levels of FSH and estradiol: after 12 cycles of treatment, the levels of FSH in three groups were decreased significantly (all P<0.01) . The levels of estradiol in three groups were increased significantly (all P<0.01) . There was no significant difference among the treatment groups at the beginning of experiment (P>0.05) . Conclusions: Both low-dose and standard-dose menopause hormone therapy (MHT) could elevate the level of estradiol, reduce bone turnover, prevent bone loss of postmenopausal women effectively. The standard dose of MHT could also increase the density of vertebrae and femoral neck, and generate more clinical benefits.

Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy and safety of long-term treatment with Cimicifuga foetida extract in menopausal women. METHODS A prospective, randomized, controlled clinical trial was conducted. A total of 96 early postmenopausal women were randomly assigned to three groups: group A received 1 mg estradiol valerate daily plus 4 mg medroxyprogesterone acetate on days 19-30; group B received 1 mg estradiol valerate daily plus 100 mg micronized progesterone on days 19-30; group C received 100 mg C. foetida extract daily. The efficacy was evaluated. Safety parameters were recorded. RESULTS A total of 81 patients completed the treatment and follow-up visit. The modified Kupperman Menopausal Index scores decreased after 3 months in all groups. No significant changes were observed in the liver, renal function and components of metabolic syndrome in group C (p > 0.05). There were no significant differences in the incidences of metabolic syndrome among the three groups (p > 0.05). After 24 months, the endometrial thickness increased significantly in group B (p = 0.014), but not in the C. foetida extract group (p > 0.05). CONCLUSIONS C. foetida extract is safe and effective for the treatment of menopausal symptoms in postmenopausal women.

Abstract
AIM To evaluate prospectively the performance of combining morphological and arterial spin labelling (ASL) magnetic resonance imaging (MRI) for detecting pseudocapsule defects in renal cell carcinoma (RCC), and to predict renal capsule invasion confirmed histopathologically. MATERIALS AND METHODS Twenty consecutive patients with suspicious renal tumours underwent MRI. Renal ASL imaging was performed and renal blood flow was measured quantitatively. The diagnostic performance of T2-weighted images alone, and a combination of T2-weighted and ASL images for predicting renal capsule invasion were assessed. RESULTS Twenty renal lesions were evaluated in 20 patients. All lesions were clear cell RCCs (ccRCCs) confirmed at post-surgical histopathology. Fifteen ccRCCs showed pseudocapsule defects on T2-weighted images, of which 12 cases showed existing blood flow in defect areas on perfusion images. To predict renal capsule invasion, the sensitivity, specificity, positive predictive value, and negative predictive value were 100%, 71.4%, 86.7%, 100%, respectively, for T2-weighted images alone, and 92.3%, 100%, 100%, 87.5%, respectively, for the combination of T2-weighted and ASL images. CONCLUSION ASL images can reflect the perfusion of pseudocapsule defects and as such, the combination of T2-weighted and ASL images produces promising diagnostic accuracy for predicting renal capsule invasion.

Abstract
BACKGROUND AND PURPOSE Intracerebral hemorrhage accounts for 6.5%-19.6% of all acute strokes. Initial intracerebral hemorrhage volume and expansion are both independent predictors of clinical outcomes and mortality. Therefore, a rapid, unbiased, and precise measurement of intracerebral hemorrhage volume is a key component of clinical management. The most commonly used method, ABC/2, results in overestimation. We developed an interactive segmentation program, SegTool, using a novel graphic processing unit, level set algorithm. Until now, the speed, bias, and precision of SegTool had not been validated. MATERIALS AND METHODS In a single stroke academic center, 2 vascular neurologists and 2 neuroradiologists independently performed a test-retest experiment that involved repeat measurements of static, unchanging intracerebral hemorrhage volumes on CT from 76 intracerebral hemorrhage cases. Measurements were made with SegTool and ABC/2. True intracerebral hemorrhage volumes were estimated from a consensus of repeat manual tracings by 2 operators. These data allowed us to estimate measurement bias, precision, and speed. RESULTS The measurements with SegTool were not significantly different from the true intracerebral hemorrhage volumes, while ABC/2 overestimated volume by 45%. The interrater measurement variability with SegTool was 50% less than that with ABC/2. The average measurement times for ABC/2 and SegTool were 35.7 and 44.6 seconds, respectively. CONCLUSIONS SegTool appears to have attributes superior to ABC/2 in terms of accuracy and interrater reliability with a 9-second delay in measurement time (on average); hence, it could be useful in clinical trials and practice.

Abstract
AIMS The lower limit of exposure to cyclosporine A (CsA) has not yet been established in donation after cardiac death (DCD) renal transplantation recipients with delayed graft function (DGF) receiving enteric-coated mycophenolate sodium (EC-MPS) therapy. Stable and adequate mycophenolic acid (MPA) dosing may facilitate lower CsA exposure after DCD renal transplantation in recipients with DGF without compromising safety. METHODS A 12-month, single-centre open-label prospective trial was performed in our centre. According to their DGF risk index using the previous DGF prediction models, we divided up the patients on oral CsA into either a DGF group (n = 26) and no DGF group (n = 48). All of the patients initially received the standard EC-MPS dosing (1440 mg/day). The initial dose of CsA in the low risk of DGF group was 4.5 mg/kg/day and in the high risk of DGF group was 2.5 mg/kg/day. Efficacy parameters, safety and tolerability were assessed over a 12-month study period. RESULTS The incidence of DGF was 18.5% in the 162 DCD recipients. Between the DGF group and the no DGF group, the 1-year patient survival and graft survival were not significantly different. The incidence of BPAR was higher in the DGF group (26.9% vs. 8.3%, p = 0.032). Most patients in the DGF group had recovery of renal function after 1 month. The adverse events between the two groups were not significantly different. The daily EC-MPS doses of the DGF group were significantly higher than the no DGF group before the 6-month follow-up period. There were no significant differences between the two groups regarding the mean AUC levels during the follow-up period. CONCLUSIONS These results show that low expose CsA with standard dosing of EC-MPS and thymoglobulin was efficacious, safe and well-tolerated in DCD renal transplant recipients with DGF in China. Furthermore, stable and adequate MPA exposure helped to reduce the dose of and exposure to CsA. Thus, this may lead to less-induced nephrotoxicity and better renal function recovery.

Abstract
Abstract
Citrullination of proteins is associated with a number of autoimmune diseases. Protein Arginine Deiminases (PADs) are a family of Ca2+ dependent enzymes that under cellular stress post-translationally convert arginine to citrulline within protein substrates to generate self-modified neo-antigens. It has been shown that presentation of citrullinated peptides on MHC class II stimulates CD4 T cells to mediate potent anti-tumor immunity (1). In this study we focus on the role of the PADI2 and PADI4 family members in colorectal cancer. Using a tissue microarray of colorectal cancers and compiling a comprehensive database of clinicopathological variables, the expression of PADI2 and PADI4 was assessed by immunohistochemistry in a study cohort. This data was used to correlate PADI2 and PADI4 expression with patient survival.
In the study cohort 462 colorectal tumors were stained for PADI2 and PADI4. Of these 171 (37%) and 231 (50%) could not be evaluated for PADI2 and PADI4 staining respectively due to the absence of enough tissue core or no evaluable tumor cells (i.e. all stroma) in the core. Of the 291 evaluable colorectal tumors stained with a PADI2 specific antibody, only 18/291 (6.2%) tumors failed to stain. A further 153/291 (52.5%) stained weakly, 102/291 (35.1%) moderate and 18/291 (6.2%) stained strongly. Of the 231 evaluable colorectal tumors stained with a PADI4 specific antibody, no tumors failed to stain. All cases stained strongly for PADI4 expression within the nucleus. In the cytoplasm 63/231 (27.3%) stained weakly, 143/231 (61.9%) moderate and 25/231 (10.8%) stained strongly.
PADI2 expression did not correlate with any clinicopathological variables whereas nuclear but not cytoplasmic PADI4 showed a strong association with histological type (p = 0.008). Kaplan-Meier analysis showed there was a correlation of PADI2 and cytoplasmic PADI4 expression with improved survival. Expression of PADI2 gave an increase in survival time from 44.8 months (95% CI 24.3 to 65.4) to 76.2 months (95% CI 69.9 to 82.4, log rank test, p = 0.012). Expression of cytoplasmic PADI4 increased survival time from 57.9 months (95% CI 43.6 to 72.3) to 77.3 months (95% CI 69.6 to 85.1, log rank test, p = 0.012). No significant correlation was observed between PADI2 and the cytoskeletal protein Vimentin or the glycolytic enzyme α-enolase both reported to be citrullinated by PAD enzymes. PADI2 expression was significantly associated with expression of the Nuclear antigen Ki67 (p = 0.046) a cellular marker for proliferation. Nuclear PADI4 significantly correlated with the cytoplasmic glycolytic enzyme α-enolase only (p = 0.001) and cytoplasmic PADI4 was highly significantly associated with α-enolase located in both the cytoplasm (p<0.001) and shorter nuclear form (p<0.001) known as MBP-1, a transcription factor known to downregulate the activity of the c-myc proto-oncogene. Cytoplasmic PADI4 expression also significantly correlated with expression of the anti-apoptotic protein Bcl2 (p = 0.028). Multivariate analysis using Cox regression showed that PADI2 (p = 0.040)/Cytoplasmic PADI4 (p = 0.036), the stress related protein MICA (p = 0.006/0.022), vascular invasion (p<0.001, 0.040) and tumor stage (p<0.001/<0.001) are all independent markers of good prognosis in colorectal cancer. These results are consistent with the hypothesis that stressed tumor cells present citrullinated epitopes allowing their growth to be controlled by T cells.

Abstract
OBJECTIVE To assess perineural invasion in prostatectomy specimen(PNIp)on tumor progression and prognosis after radical prostatectomy. METHODS Retrospective analysis including 502 prostate cancer patients admitted in Renji Hospital, School of Medicine, Shanghai Jiaotong University from December 2002 to May 2014 was studied.Differences of serum prostate specific antigen(PSA), Gleason score of prostate biopsy, Gleason score of prostatectomy specimen, tumor stage, capsular invasion, positive surgical margin, seminal invasion, pelvic lymph node metastasis, nadir PSA were analyzed in patients with PNIp and without PNIp. Logistic regression analysis, Log-rank test and Cox regression analysis was used to analyzed the data, respectively. RESULTS There were 91 patients with PNIp(18.1%) and 411 patients without PNIp(81.9%). Differences of serum PSA, Gleason score of prostate biopsy, Gleason score of prostatectomy specimen, tumor stage, capsular invasion, seminal invasion, nadir PSA between the two groups were found(all P<0.05). In the multivariable logistic regression analysis, PNIp was independent predictor of Gleason score of prostate biopsy, Gleason score of prostatectomy specimen, tumor stage, capsular invasion(OR=1.515, 1.955, 2.069, 1.859, all P<0.05). One hundred and twenty-one patients with biochemical serum recurrence(26.7%). Serum PSA, Gleason score of prostate biopsy, Gleason score of prostatectomy specimen, tumor stage, PNIp, seminal invasion were related to biochemical serum recurrence(P<0.05). In the multivariable cox regression analysis, serum PSA, Gleason score of prostate biopsy, PNIp, seminal invasion were independent predictors of biochemical serum recurrence(HR=1.021, 1.441, 1.663, 3.257, all P<0.05). CONCLUSION PNIp is the important predictor of the tumor progression and prognosis of prostate cancer.

Abstract
BACKGROUND Hyperfibrinogen is thought to be associated with a higher risk of invasion and metastasis, as well as a worse outcome for multiple types of cancer. However, the prognostic significance of plasma fibrinogen has not been investigated in prostate cancer with hormonal therapy. The objective of this study was to evaluate its roles in prostate cancer patients treated with androgen deprivation therapy (ADT). METHODS A total of 290 patients who underwent ADT as first-line therapy for prostate cancer were retrospectively analyzed. The fibrinogen level was measured at the time of diagnosis. Patients were categorized using a cutoff point of 3.225 g l(-1) according to a calculation by the receiver operating curve analysis. Correlations between the fibrinogen and clinical characteristics were analyzed. Meanwhile, univariable and multivariable cox regression analyses were performed to determine the associations of fibrinogen with progression-free survival (PFS), cancer-specific survival (CSS) and overall survival (OS). Prognostic accuracy was evaluated with the Harrell concordance index. RESULTS Compared with patients with a lower fibrinogen level (<3.225 g l(-1)), patients with a higher fibrinogen level were more likely to have higher PSA, Gleason score, risk stratification and incidence of metastasis (P<0.05). Multivariable analyses identified hyperfibrinogen as an independent prognostic factor for PFS (hazard ratio (HR)=2.000, P<0.001), CSS (HR=2.209, P=0.006) and OS (HR=1.965, P=0.009). The final models built by the addition of fibrinogen improved predictive accuracy (c-index: 0.750, 0.799 and 0.767) for PFS, CSS and OS compared with the clinicopathological base models (c-index: 0.730, 0.778 and 0.746), which included Gleason score and metastasis. CONCLUSIONS The pretreatment plasma fibrinogen level was associated with tumor progression and might have a significant role in the prognosis of the prostate cancer patients treated with ADT. Thus, we recommend adding fibrinogen to traditional prognostic model, which may improve its predictive accuracy.

Abstract
Ectodermal dysplasia (ED) represents a collection of rare disorders that result from a failure of development of the tissues derived from the embryonic ectoderm. ED is often associated with hair, teeth, and skin abnormalities, which are serious conditions affecting the quality of life of the patient. To date, a large number of genes have been found to be associated with this syndrome. Here, we report a patient with hypohidrotic ED (HED) without family history. We identified that this patient's disorder arises from an X-linked HED with a mutation in the EDA gene (G299D) found by whole-exome sequencing. In addition, in this paper we summarize the disease-causing mutations based on current literature. Overall, recent clinical and genetic research involving patients with HED have uncovered a large number of pathogenic mutations in EDA, which might contribute to a full understanding of the function of EDA and the underlying mechanisms of HED caused by EDA mutations.

Abstract
BACKGROUND Endothelin-1 (ET-1) induces pain-like behavior in animals and man by activating the Gq protein-coupled receptor endothelin-A (ETA ). Activation of ETA receptors on nociceptor membranes evokes intracellular calcium transients and alters membrane Na(+) and K(+) channel and TRPV1 currents, leading to neuronal hyper-excitability manifested by spontaneous and evoked pain behaviors in vivo. In addition to blocking sodium channels, local anesthetics inhibit the Gq protein-coupled signaling of several inflammatory and pro-algesic mediators. In this study, we aimed to investigate the actions of local anesthetics on ETA -mediated increases in intracellular calcium in ND7/104 model sensory neurons. METHODS Increases in intracellular calcium were measured by the fluorescent indicator fura-2 in a sensory neuron-derived cell line (ND7/104), which endogenously expresses ETA receptors. Effects of lidocaine and bupivacaine, along with their respective membrane-impermeant derivatives QX-314, LEA-123 and LEA-124, on peak calcium responses to ET-1 were measured. RESULTS Bupivacaine suppressed ET-1 responses in a concentration-dependent and non-competitive manner with an IC50 of 3.79 ± 1.63 mM. Bupivacaine (6 mM) reduced the Emax for ET-1 from 50.07 ± 1.91 mM to 27.30 ± 2.92 mM. The actions of bupivacaine occurred quickly and were rapidly reversible. Membrane-impermeant analogs of bupivacaine (LEA-123 and LEA-124, 6 mM) were without effect, as was lidocaine (10 mM) and its quaternary derivative QX-314 (10 mM). CONCLUSION Bupivacaine inhibits ETA -mediated calcium transients at clinically relevant concentrations through an intracellular target. The anti-inflammatory and analgesic actions of bupivacaine may be at least partially due to its inhibitory action on Gq -coupled receptors, including ETA.

Abstract
AIMS To investigate the pharmacokinetics of enteric-coated mycophenolate sodium (EC-MPS) and the clinical outcome in kidney transplant recipients in the early post-transplantation phase. Then explain which regimen is more suitable for Chinese renal transplant recipients. METHODOLOGY In total, 60 de novo kidney transplant recipients treated with tacrolimus and steroids were randomised to receive EC-MPS at standard dose (SD; 1440 mg/day; n = 28) or low dose (LD; 1080 mg/day; n = 32). Efficacy parameters, safety and tolerability were assessed over a 6-month study period. Full mycophenolic acid (MPA) areas under the curve (AUCs) were completed on days 3 and 5, whereas a three-point limited sampling strategy (LSS) was utilised for MPA AUC assessments at 2 weeks and months 1, 3 and 6 (the LSS for three-time-point MPA AUC 0-12 h (mg h/l) = 15.99 + 0.87C1 h + 0.68C2 h + 7.85C4 h ; r(2) = 0.8670. RESULTS The mean AUC levels at day 3 and day 5 in the SD group were significantly higher than in the LD group (57.4 mg·h/l vs. 38.2 mg·h/l and 59.3 mg·h/l vs. 44.8 mg·h/l, respectively, p < 0.01). There was a trend for fewer clinically diagnosed acute rejections in the SD group vs. the LD group at 6 months (7.1% vs. 12.5%). This trend was also present when acute rejection was analysed as biopsy-proven cases. There were significantly more acute rejections (all definitions) in patients with MPA AUC levels < 30 mg·h/l compared with those with MPA AUC levels ≥ 30 mg·h/l within 6 months (p < 0.05). Renal function, incidence of infection and haematological disorders were not significantly different in either study group. CONCLUSIONS Early adequate MPA exposure in renal transplant recipients can be achieved with a higher starting dose. In addition, a SD regimen was as well-tolerated as a LD regimen. Furthermore, early adequate MPA exposure significantly lowered the rate of acute rejection without compromising safety and tolerability.

Abstract
Disturbance is common and can fragment clones of plants. Clonal fragmentation may affect the density and growth of ramets so that it could alter intraspecific competition. To test this hypothesis, we grew one (low density), five (medium density) or nine (high density) parent ramets of the floating invasive plant Pistia stratiotes in buckets, and newly produced offspring ramets were either severed (with fragmentation) or remained connected to parent ramets (no fragmentation). Increasing density reduced biomass of the whole clone (i.e. parent ramet plus its offspring ramets), showing intense intraspecific competition. Fragmentation decreased biomass of offspring ramets, but increased biomass of parent ramets and the whole clone, suggesting significant resource translocation from parent to offspring ramets when clones were not fragmented. There was no interaction effect of density x fragmentation on biomass of the whole clone, and fragmentation did not affect competition intensity index. We conclude that clonal fragmentation does not alter intraspecific competition between clones of P. stratiotes, but increases biomass production of the whole clone. Thus, fragmentation may contribute to its interspecific competitive ability and invasiveness, and intentional fragmentation should not be recommended as a measure to stop the rapid growth of this invasive species.
