Abstract
AIM To quantitatively evaluate blood-brain barrier (BBB) permeability in the perihaematomal region of spontaneous intracerebral haemorrhage (ICH) and investigate the association between the alterations in cerebral blood flow and BBB permeability around the haematoma. MATERIALS AND METHODS Spontaneous ICH patients underwent unenhanced computed tomography (CT) and CT perfusion (CTP) simultaneously. Haematoma volume was measured on CT. The values of cerebral haemodynamic parameters including cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), time to peak (TTP), and permeability-surface area product (PS) were measured in the perihaematomal region and the contralateral mirror region, and then relative values were calculated for statistical analysis. Linear regression was used to evaluate associations between BBB permeability and variables. RESULTS A total of 87 ICH patients were included in this study. The focally elevated BBB permeability was observed in the perihaematomal region in ICH patients. Linear regression showed that reduced rCBF (β = -0.379, p=0.001) and increased rCBV (β = 0.412, p=0.000) correlated independently with increased relative PS (rPS) value in deep ICH, while only increased rCBV (β = 0.423, p=0.071) correlated to increased rPS value in patients with lobar ICH. CONCLUSIONS BBB permeability is focally elevated in the region around the haematoma. Cerebral haemodynamic alterations are associated with increased BBB permeability. Cerebral hypoperfusion may aggravate BBB compromise, and a compensatory increase in CBV may lead to reperfusion injury on BBB.

Abstract
Primary biliary cholangitis is a chronic autoimmune cholestatic disease with a progressive course. This disease is not rare in China, but standardized diagnosis and treatment for primary biliary cholangitis are insufficient. Based on the evidence and guidelines from China and other countries, Rheumatology Branch of Chinese Medical Association developed the recommendations of diagnosis and treatment for primary biliary cholangitis in China. The aim is to help clinicians recognize clinical characters, therapeutic selection and prognosis judgement of primary biliary cholangitis, which will contribute to make diagnosis in time, to select treatment properly and to manage follow-up scientifically.

Abstract
Objective To explore the clinical characteristics of relapsing polychondritis(RP)patients presented with arthropathy. Methods We retrospectively analyzed the clinical data of 201 RP patients who were hospitalized in our center between December 2005 and February 2019.After 16 patients with co-existing other autoimmune diseases and malignancies were ruled out,185 RP patients entered the final analysis,among whom 16 RP patients were presented with arthropathy and 169 without arthropathy.The demographic data,clinical manifestations,laboratory findings,and prognosis were compared between these two groups. Results Five of the 16 RP patients with arthropathy at presentation were misdiagnosed as rheumatoid arthritis.Compared with RP patients without arthropathy at presentation,RP patients with arthropathy at presentation had a longer disease course[(37.50±66.50)months vs.(9.00±11.00)months,z=-3.186,P =0.001],longer time of diagnostic delay[(24.00±41.25)months vs.(7.00±9.00)months,z=-2.890,P=0.004],and higher incidence of eye(62.50% vs. 36.09%,χ2=4.309,P=0.038)and nervous system involvements(43.75% vs. 15.38%,χ2=6.205,P=0.013). Conclusions RP patients with arthropathy at presentation are most likely to be misdiagnosed as rheumatoid arthritis.These patients are characterized by longer disease course and diagnostic delay and more frequrent eye and nervous system involvements.

Abstract
Thrombocytopenia is the main clinical manifestation or common complication of multiple diseases, but there is still a lack of systematic understanding of pathogenesis, underlying diseases and treatment strategies of thrombocytopenia. Based on evidence-based medicine, this consensus summarizes seven aspects related to thrombocytopenia, including definition, epidemiology, pathogenesis, clinical manifestations, laboratory examination, diagnosis and treatment. This consensus provides an important reference for the diagnosis and treatment of thrombocytopenia.

Abstract
OBJECTIVES The aim of this study was to investigate the predictive factors for relapse of IgG4-related disease (IgG4-RD) and observe the long-term clinical outcomes in patients with IgG4-RD. METHODS We included in the present analysis 122 patients who were newly diagnosed with IgG4-RD, treated with glucocorticoid (GC) monotherapy or GC and immunosuppressant combination therapy, and followed for at least 3 years. Clinical relapse, response and side effects were recorded. RESULTS The cumulative relapse rates of patients in this study were 10.66%, 22.95% and 27.87% at 12, 24 and 36 months, respectively. Complete drug withdrawal was an independent risk factor for disease relapse. Higher serum IgG4 concentrations, involvement of more organs, higher IgG4 RI scores and elevation of eosinophils at baseline were closely associated with disease relapse. Re-elevation of serum IgG4 concentrations and low GC maintenance dosage during the follow-up period were significantly associated with clinical relapse. The GC dosage should be more than 6.25 mg day-1 as monotherapy during the maintenance stage; moreover, combining with immunosuppressants can reduce the GC dosage. Adding GC or immunosuppressants for patients with re-elevation of serum IgG4 levels could prevent later disease relapse. No serious complications were noted during long-term follow-up. CONCLUSIONS The combination of GC with immunosuppressants was more effective than GC monotherapy during the steroid tapering and maintenance stages. Higher serum IgG4 levels, involvement of more organs, higher IgG4 RI scores, history of allergy, eosinophil elevation at baseline, re-elevation of serum IgG4 levels and lower GC maintenance dosage at follow-up might be predictive of relapse.

Abstract
Objective: To investigate the clinical characteristics of polyarteritis nodosa (PAN) patients with renal involvement. Methods: PAN patients admitted to the department of rheumatology, department of pediatrics, department of nephrology, general internal medicine department and department of vascular surgery at Peking Union Medical College Hospital from June 2012 to August 2018 were enrolled in this study and were divided into two groups according to renal involvement or not. The clinical characteristics were analyzed. Results: A total of 94 PAN patients were finally enrolled and 57 (60.64%) presented kidney manifestation. The mean age of onset was (37.76±17.40) years old and the interval from onset to diagnosis was 10 (0 to 240) months. Forty patients were misdiagnosed once or more times. In patients with renal involvement, 9 cases suffered from renal ischemia or infarction, 31 with microscopic haematuria, 26 with proteinuria, renal artery or its branch involved in 17 cases, renal vein thrombosis in 1 case, 4 cases with pyeloureterectasis, one case with renal fascia thickening, 33 cases with impaired renal function (serum creatinine>84 μmol/L) including creatinine>140 μmol/L in 10 patients. Renal artery branch stenosis was the most common presentation [9 cases (52.94%)] of renal vascular involvement, other abnormalities including nodular dilatation [4 cases (23.53%)], occlusion [3 cases (17.65%)]. There were significant differences (P<0.05) in the PAN patients with and without renal involvement in the following: age of onset [(33.72±16.13) years vs. (43.97±17.66) years, t(2)=2.901, P=0.005], weight loss(≥4kg since PAN onset) [25(43.86%) vs. 7(18.92%), χ(2)=6.216, P=0.013], elevation of diastolic blood pressure [22(38.60%) vs. 7(18.92%), χ(2)=4.072, P=0.044], acromegaly gangrene [18(31.58%) vs. 21(56.76%), χ(2)=5.859, P=0.015], and gastrointestinal artery involvement [20(35.09%) vs. 6(1.22%), χ(2)=3.993, P=0.046]. Laboratory parameters and the application of glucocorticoid and cyclophosphamide therapies were similar in two groups (all P>0.05). Conclusion: Young PAN patients are more likely to be associated with renal involvement, especially gastrointestinal arteries.

Abstract
Objective: To evaluate senior resident training program "resident team leader in the Department of General Internal Medicine" at Peking Union Medical College Hospital. Methods: We surveyed the residents or the fellows who had been selected as resident team leaders and received the training from October 2014 to September 2018 on their comments and suggestions. Results: Twenty-two rotated senior residents who were selected as team leaders in the Department of General Internal Medicine completed the survey. Almost all (21/22, 95.5%) of the respondents reported that they learnt more in general as team leaders by Visual Analog Scale (VAS). The mean VAS scores of clinical skills were 7.23±1.27, 7.86±1.32 in teaching abilities, 8.14±0.89 in leadership evaluation. Scales as chief resident assistants were 8.44±1.26. Sixteen respondents (72.7%) considered that pre-job training by attending doctors was necessary. Another 8 (36.4%) respondents addressed their demands on training of teaching skills. Conclusions: The senior resident training program "resident team leader in the Department of General Internal Medicine" improves the competency of rotated senior residents. It is a valuable pilot study on senior resident training and worthy of further application in other departments and hospitals.

Abstract
A 45-year-old woman was admitted to the Department of Rheumatology and Immunology, Peking Union Medical College Hospital, due to weakness of the upper limbs, fever, and blurred vision. She was clinically diagnosed as systemic lupus erythematosus overlapped primary biliary cirrhosis, with renal, retinal, hematological and musculoskeletal involvement, combined with severe pulmonary infection and respiratory failure. Treated with glucocorticoids, ursodeoxycholic acid, antibiotics and respiratory support, the patient got better. A couple of days later, her fever recurred and platelets count dropped to 30×10(9)/L, hemoglobin to 78 g/L, fibrinogen to<1.5 g/L, ferritin to 1 640 ng/ml, natural killer (NK) cell count to 8/μl, the activity of NK cells 2% (reference value 9.5%-23.5%), considering the occurrence of hemophagocytic lymphohistiocytosis (HLH). Cytomegalovirus pp65 antigenemia test: 13 positive cells/2×10(5) WBC. Considered the possibility of HLH caused by cytomegalovirus infection and treated by 250 mg ganciclovir intravenous drip twice a day for a full course. The temperature of the patient was gradually reduced to 36.5 ℃, the count of platelets were increased to 229 ×10(9)/L, the hemoglobin was increased to 94 g/L, and the fibrinogen was increased to 3.26 g/L. When there were unexplained critical signs of the primary disease during systemic lupus erythematosus treatment, severe complications such as infection, HLH, thrombotic thrombocytopenic purpura should be taken into account.

Abstract
Dengue is the most prevalent and rapidly spreading mosquito-borne viral disease. As a dengue non-endemic country, China has experienced several dengue outbreaks in recent years. However, dengue patients in China displayed distinct clinical characteristics compared to patients in endemic countries. To standardize the diagnosis and treatment of dengue fever, the experts of the Society of Infectious Diseases, Society of Tropical Medicine and Parasitology of Chinese Medical Association, and the Society of Emergency Medicine, China Association of Chinese Medicine have reached this guideline based on guidelines for diagnosis, treatment, prevention and control of dengue (World Health Organization, 2009); guidelines for diagnosis and treatment of dengue (National Health and Family Planning Commission of the People's Republic of China, 2014, Edition 2), health industry standard of the People's Republic of China "diagnosis for dengue fever (WS216-2018)" and systemic reports on dengue. The guideline includes 8 aspects: introduction, terminology, epidemiology and prevention, etiology and pathogenesis, clinical features, diagnosis, treatment and problems to be solved.

Abstract
Objective: To investigate the sensitivity and specificity of commercial nonstructural protein 1 (NS1) testing kits for Dengue fever diagnose, and provide the evidence for diagnostic criteria revision. Methods: 300 PCR or virus isolation positive blood samples for dengue virus were collected from sentinel hospitals for dengue surveillance in Guangzhou, Dongguang and Zhongshang from May 2015 to Nov. 2016. At the same time, 308 PCR negative samples for Dengue virus were collected as control group. The information of the sample was collected using questionnaires. These samples were tested using imported and domestic ELISA and the colloidal gold-labeled kits that were widely used for detecting dengue NS1. Sensitivity, specificity and coincidence were calculated and analyzed, and Z hongshan's result was regarded as the reslut of the third part. Results: The positive group includes 133 males and 167 females, average ages are 47.2±13.3, 179, 110 and 11 of them is Dengue Ⅰ, Ⅱ and Ⅲ respectively. The negative group includes 154 males and 154 females, average ages are (40.1±11.6) years old. The sensitivity of domestic ELISA Kits (94.5%) is less than imported (99.5%), and the result has statistical significance (χ(2)=8.59, P=0.030), the specificity is 99.7% and 97.7% respectively; The sensitivity of imported and domestic the colloidal gold-labeled Kits is 97.5% and 96.5% respectively, both of specificities are 100%. The sensitivity and specificity of Dengue Ⅰ for NS1 test are more than 97.0%. The sensitivity of domestic ELISA and gold-labeled Kits is 90.0% and 95.0%, and the specificity is 96.8% and 100% respectively for Dengue Ⅱ test. The sensitivity of imported ELISA and gold-labeled Kits is 100% and 98.0%, and the specificity is 99.4% and 100% respectively for Dengue Ⅱ test. The result of the third party show the sensitivity and specificity of domestic ELISA and gold-labeled Kits are 90.0% and 98.0%, the differences has statistical significance (χ(2)=5.67, P=0.020). Conclusion: NS1 testing can be used as early dengue fever diagnose for higher sensitivity and specificity.

Abstract
Objective: To assess the value of internal medicine residency training program at Peking Union Medical College Hospital (PUMCH), and the feasibility of applying revised Milestones evaluation system. Methods: Postgraduate-year-one to four (PGY-1 to PGY-4) residents in PUMCH finished the revised Milestones evaluation scales in September 2017. Residents' self-evaluation and faculty-evaluation scores were calculated. Statistical analysis was conducted on the data. Results: A total of 207 residents were enrolled in this cross-sectional study. Both self and faculty scores showed an increasing trend in senior residents. PGY-1 residents were assessed during their first month of residency with scores of 4 points or higher, suggesting that residents have a high starting level. More strikingly, the mean score in PGY-4 was 7 points or higher, proving the career development of residency training program. There was no statistically significant difference between total self- and faculty-evaluation scores. Evaluation scores of learning ability and communication ability were lower in faculty group (t=-2.627, -4.279, all P<0.05). The scores in graduate students were lower than those in standardized training residents. Conclusions: The goal of national standardized residency training is to improve the quality of healthcare and residents' career development. The evaluation results would guide curriculum design and emphasize the importance and necessity of multi-level teaching. Self-evaluation contributes to the understanding of training objectives and personal cognition.

Abstract
Objective: To evaluate the feasibility of detecting index of microcirculatory resistance (IMR) and the relationship between IMR and left ventricular (LV) systolic function after acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI). Methods: The patients with first AMI received primary PCI in Peking University Third Hospital were enrolled from January 2014 to March 2016. IMR were measured immediately after PCI by using pressure/temperature wire. The relationship between IMR and left ventricular ejection fraction (LVEF) assessed by echocardiography at first day and 6 months after admission was evaluated. Results: Twenty-eight patients with anterior wall AMI were enrolled, with an average age (56±13) years. The success rate of IMR detection was 100%. The mean IMR was (33±18 )mmHg·s. There was no complication related to intravenous adenosine triphosphate (ATP) (140 μg· kg(-1)· min(-1)). The IMR was negatively correlated with TIMI blood flow grade after primary PCI (r=-0.386, P=0.043), and positively correlated with female gender, CK peak value and TnT peak value (r=0.430, P=0.022; r=0.431, P=0.025; r=0.434, P=0.024). After 6 months of follow-up, no adverse cardiovascular events (including cardiac death, nonfatal myocardial infarction, malignant arrhythmia, unplanned revascularization, hospitalization for unstable angina pectoris and severe heart failure requiring hospitalization) occurred. LVEF increased significantly compared with the first day after PCI (0.54±0.08 vs 0.47±0.06, P=0.001), and IMR was negatively correlated with LVEF after 6 months (r=-0.477, P=0.014). Multivariable linear regression analysis showed that CK peak and IMR were predictors of LVEF after six months ( β=-0.595, t=-3.814, P=0.01; β=-0.352, t=-2.26, P=0.036). Conclusions: Immediate detection of IMR in patients with anterior wall AMI after PCI is safe and feasible. The immediate IMR after PCI reflects the extent of myocardial necrosis and myocardial perfusion, and is a predictor of LVEF at 6 months after PCI.

Abstract
OBJECTIVES This study aimed to examine the long-term efficacy, remission and survival of patients with severe systemic lupus erythematosus (SLE) after the combination treatment with high-dose immunosuppressive therapy (HDIT) and autologous peripheral blood stem cell transplantation (APBSCT). METHODS Chinese patients with severe SLE receiving combination therapy with HDIT and APBSCT in Peking Union Medical College Hospital were enrolled from July 1999 to October 2005. Disease activity, treatment, and adverse effects of these patients were evaluated. The 10-year overall survival and 10-year remission survival were also analysed. RESULTS Among the 27 patients, one patient failed to collect enough CD34+ cells and data was missing for two patients. In the end, 24 patients were included in the final analysis. After APBSCT, one patient died, two patients achieved partial remission and 21 (87.5%) achieved remission at 6 months. The median follow-up duration of the 23 patients was 120 months. Fourteen patients had completed a ten-year follow-up. The median proteinuria level of the 14 patients with LN with ten years of follow-up significantly decreased from 4.00 g/24 hours at pre-treatment to 0.00g/24 hours at year 5 and 0.00 g/24 hours at year 10 (both p=0.001). The 10-year overall survival rate and 10-year remission survival rate were both 86.0% (95% CI: 71.1-100.9%). After a median follow-up for 120 months, 16 patients (66.7%) remained in remission, 4 patients were lost to follow-up, 2 patients died and 1 patient remained active. CONCLUSIONS The combination of HDIT and APBSCT may be an option to improve the survival of severe lupus patients.

Abstract
A retrospective case control study was conducted in the Peking Union Medical College Hospital. Medical records were reviewed for demographic data, clinical features, laboratory results, systemic lupus erythematosus (SLE) disease activity evaluations, and ophthalmic examinations to investigate the clinical characteristics and significance of retinal vasculopathy (RV) in Chinese patients with systemic lupus erythematosus. The prevalence of RV was approximately 0.66% (35/5298) in SLE patients. A total of 60 eyes were involved. The ocular presentations included decrease of visual acuity (48/60, 80%), visual field loss (7/60, 11.7%), and diplopia (3/60, 5%). Ophthalmic fundoscopic examination revealed cotton-wool spots (30/60, 50%), retinal vascular attenuation (31/60, 51.6%), and hemorrhages (41/60, 68.3%). Retinal angiogram showed that 72.7% (16/22) eyes had vaso-occlusion. The ophthalmic episodes could occur at any stage of SLE duration, with a median of 12 months (0-168 months) following SLE onset. Twenty-one (35%) eyes did not recover, or even worsened, during hospital stay. RV was found to be significantly associated with neuropsychiatric lesions (51.4% vs. 21.3%, p = .005) and hematological disturbance (62.9% vs. 34.3%, p = .005). SLE patients with RV had significantly higher SLE disease activity index scores than controls (19.9 ± 0.9 vs. 10.2 ± 0.7, p < .001). An inverse association of anti-SSA antibody with RV was detected (34.3% vs. 67.1%, p = .001). Nervous system disturbance (odds ratio (OR) = 4.340, 95% confidence interval (CI) 1.438, 13.094, p = .009) and leukocytopenia (OR = 6.385, 95% CI 1.916, 21.278, p = .003) were independent risk factors, while anti-SSA antibody positivity (OR = 0.249, 95% CI 0.087, 0.710, p = .009) was a protective factor for RV in SLE patients. In certain cases, RV is a threatening condition for SLE patients presenting with clinical ocular manifestations. Ophthalmo-fundoscopic detection is recommended as soon as SLE is diagnosed.

Abstract
Objective: To study the morphologic changes of immunotactoid glomerulopathy and to investigate the clinical pathological features and differential diagnosis. Methods: Renal biopsy was observed under the light microscope, immunofluorescence and electron microscopy in a case of newly diagnosed immunotactoid glomerulopathy. Results: This patient clinically presented with nephrotic syndrome and hypertension, without family history of renal diseases. Light microscopy showed that diffusely massive and specific protein deposition in the glomerulus in Masson staining. Immunofluorescence revealed IgG, C3 and κ were deposited along the capillary walls and mesangial regions. Electron microscopic examination showed that a large amount of microtubule like substances and a small amount of long bar-shaped and dense crystal-like substances were deposited in the subendothelial spaces and mesangial areas. Conclusions: Light microscopy and immunofluorescence of immunotactoid glomerulopathy show no specifically pathological changes. Under electron microscope, a large amount of microtubule like substances is deposited in the glomerulus, which is the key point to distinguish this disease from other glomerular diseases. Except for the microtubule-like substances, the present case is accompanied by the deposition of long bar-shaped and dense crystal-like substance, which has not been reported in previous studies.

Abstract
Primary biliary cholangitis (PBC), hitherto called primary biliary cirrhosis, is a cholestatic liver disease of unclear aetiology with autoimmune features. Accumulating evidence revealed that γδ T cells were involved in the development of autoimmune diseases. As one of γδ T cells subsets, however, the role of Vδ1 T cells in the immunopathogenesis of PBC is poorly understood. We analysed peripheral blood Vδ1 T cells in PBC patients in active stage (ASP, n = 18), adequate responders (AR, n = 10) and inadequate responders (IAR, n = 4) to ursodeoxycholic acid (UDCA) and an age-matched healthy control group (n = 16) by flow cytometric analysis. The ASP group exhibited a significantly higher proportion and absolute number of Vδ1 T cells, which were also observed in immunofluorescence staining of liver biopsy specimens of PBC patients. Moreover, these Vδ1 T cells expressed a series of activation markers and intracellular cytokines, which may contribute to the immunopathogenesis of PBC. Our study will help to clarify the role of Vδ1 T cells in the development of PBC.

Abstract
In order to enhance the mechanical strength of Low-E glass, Fluorine-doped tin oxide (FTO) films have to be tempered at high temperatures together with glass substrates. The effects of tempering temperature (600 °C ~ 720 °C) and time (150 s ~ 300 s) on the structural and electrical properties of FTO films were investigated. The results show all the films consist of non-stoichiometric, polycrystalline SnO2 without detectable amounts of fluoride. 700 °C and 260 s may be the critical tempering temperature and time, respectively. FTO films tempered at 700 °C for 260 s possesses the resistivity of 7.54 × 10(-4) Ω • cm, the average transmittance in 400 ~ 800 nm of ~80%, and the calculated emissivity of 0.38. Hall mobility of FTO films tempered in this proper condition is mainly limited by the ionized impurity scattering. The value of [O]/[Sn] at the film surface is much higher than the stoichiometric value of 2.0 of pure crystalline SnO2.

Abstract
OBJECTIVES Our objective was to better understand the roles of single nucleotide polymorphisms (SNPs) in the CCL21, ERBB3, and TERT genes region in the development of idiopathic inflammatory myopathies (IIMs), we explored the associations between SNPs in the mentioned three genes and IIMs susceptibility in a Chinese Han population. METHODS Chinese polymyositis (PM) patients (n =291), dermatomyositis (DM) patients (n=526) and ethnically-matched healthy controls (n =968) were genotyped for the CCL21 region SNPs (rs951005 and rs2492358), ERBB3 (rs2292239 and rs11171739), and TERT (rs2853676 and rs10069690), by using the Sequenom MassArray system. RESULTS Our study indicated strong allele and genotype associations between rs951005 (OR: 1.65, 95%CI: 1.18-2.30, Pc=0.015; Pc=0.041, respectively) in CCL21 gene and PM patients. Additionally, rs951005 was associated with interstitial lung disease (ILD) in PM patients (Pc =0.01), and was associated with PM patients in additive model. However, the Chinese Han PM/DM patients and controls had statistically similar frequencies of alleles, genotypes and different genetic models (additive, dominant, and recessive) of ERBB3 and TERT polymorphisms. CONCLUSIONS This was the first study to demonstrate that the CCL21 gene SNP (rs951005) might confer genetic predisposition to PM patients or such patients with ILD in a Chinese Han population.

Abstract
TUSC3 interacts with the protein phosphatase 1 and magnesium ion transport system, which plays an important role in learning and memory. Abnormal conditions of learning and memory are common clinical characteristics of mental retardation (MR). However, the association of TUSC3 genetic polymorphisms with MR remains unknown. A total of 456 DNA samples including 174 nuclear families containing MR were collected in the Qinba mountain area of China. The genotypes of eight tag single nucleotide polymorphisms of TUSC3 were evaluated with traditional genetic methods. Family-based association tests, transmission disequilibrium tests (TDTs), and haplotype relative risk (HRR) analyses were performed to investigate the association between genetic variants of the TUSC3 gene and MR. The genetic polymorphisms rs10093881, rs6530893, and rs6994908 were associated with MR (all P values <0.05) based upon the results of single-site TDT and HRR analyses. The haplotype block consisting of rs6530893 and rs6994908, harboring the sixth exon of TUSC3, was also associated with MR (all P values <0.05). This study demonstrated an association between genetic polymorphisms of the TUSC3 gene and MR in the Qinba mountain area, the sixth exon of which might contribute to the risk of MR. However, further studies are needed on the causal mechanisms in this association.

Abstract
We enrolled and reviewed 26 medical records of systemic lupus erythematosus (SLE) with intracranial hemorrhage (cases) and 104 randomly matched records of SLE without intracranial hemorrhage (controls) out of 6653 admitted patients at Peking Union Medical College Hospital from 1994 to 2012, to analyze the clinical characteristics and risk factors of intracranial hemorrhage in SLE. The incidence of SLE with intracranial hemorrhage was only 0.39% within the last 18 years at Peking Union Medical College Hospital. However, the in-hospital fatality rate was quite high (23.1%). Headache was the most common symptom (53.5%) in SLE patients with intracranial hemorrhage. The anatomical localization of the hemorrhages in the brain was predominantly located in the cerebrum. Intracranial hemorrhage could happen in either stable or active SLE patients. SLE patients with intracranial hemorrhage presented other neuropsychiatric syndromes defined by the American College of Rheumatology (ACR) in 1999, thrombocytopenia and antiphospholipid syndrome more frequently than controls. Thrombocytopenia was the independent risk factor for intracranial hemorrhage coexisting with SLE (OR=3.687, 95% CI 1.510-9.001, p=0.004).

Abstract
FGD1 encoding a guanine nucleotide exchange factor, specifically activates Rho GTPase cell division cycle 42 (Cdc42). Dysfunction of FGD1 causes Aarskog-Scott syndrome (MIM #305400), an X-linked disorder that may affect bone and intellectual development. However, the relationship between FGD1 and intellectual developmental disorders (IDD) remains unclear. The purpose of this study was to investigate the genetic association between the FGD1 polymorphism and IDD. Working with families from the Qinba mountain area where the occurrence of IDD is higher than the average in China, we analyzed 456 samples from 130 nuclear families, effectively controlling for stratification and environmental factors. Five SNP loci (rs2230265, rs7881608, rs2239809, rs6614244, and rs2284710) were selected that were well distributed within the FGD1 gene. Genotyping was performed through single-strand conformation polymorphism and restriction fragment length polymorphism. The data were analyzed with transmission disequilibrium tests. In the Qinba mountain area, no significant association was observed between IDD and allele or genotype frequencies, or the haplotype of the 5 SNP loci of the FGD1 gene. The results indicate that FGD1 may not be a monogenetic X-linked factor in IDD. Further studies are required to investigate its role in intellectual development based on its specific interactions with Cdc42 or other partner proteins contributing to IDD.

Abstract
It has been shown that cytokines can act as molecular adjuvant to enhance the immune response induced by DNA vaccines, but it is unknown whether interleukin 33 (IL-33) can enhance the immunocontraceptive effect induced by DNA vaccines. In the present study, we explored the effects of murine IL-33 on infertility induced by Lagurus lagurus zona pellucida 3 (Lzp3) contraceptive DNA vaccine administered by the mucosal route. Plasmid pcD-Lzp3 and plasmid pcD-mIL-33 were encapsulated with chitosan to generate the nanoparticle chi-(pcD-Lzp3+pcD-mIL-33) as the DNA vaccine. Sixty female ICR mice, divided into 5 groups (n=12/group), were intranasally immunized on days 0, 14, 28, and 42. After intranasal immunization, the anti-LZP3-specific IgG in serum and IgA in vaginal secretions and feces were determined by ELISA. The results showed that chi-(pcD-Lzp3+pcD-mIL-33) co-immunization induced the highest levels of serum IgG, secreted mucosal IgA, and T cell proliferation. Importantly, mice co-immunized with chi-(pcD-Lzp3+pcD-mIL-33) had the lowest birth rate and mean litter size, which correlated with high levels of antibodies. Ovaries from infertile female mice co-immunized with chi-(pcD-Lzp3+pcD-mIL-33) showed abnormal development of ovarian follicles, indicated by atretic follicles and loss of oocytes. Our results demonstrated that intranasal delivery of the molecular adjuvant mIL-33 with chi-pcD-Lzp3 significantly increased infertility by enhancing both systemic and mucosal immune responses. Therefore, chi-(pcD-Lzp3+pcD-mIL-33) co-immunization could be a strategy for controlling the population of wild animal pests.

Abstract
The theoretical description of the anomalous properties of the pseudogap phase in the underdoped region of the cuprate phase diagram lags behind the progress in spectroscopic and other experiments. A phenomenological ansatz, based on analogies to the approach to Mott localization at weak coupling in lower dimensional systems, has been proposed by Yang et al (2006 Phys. Rev. B 73 174501). This ansatz has had success in describing a range of experiments. The motivation underlying this ansatz is described and the comparisons with experiment are reviewed. Implications for a more microscopic theory are discussed together with the relation to theories that start directly from microscopic strongly coupled Hamiltonians.

Abstract
B-cell activating factor belonging to tumour necrosis factor family (BAFF) is essential for B-cell survival and function through interaction with its receptors BAFF receptor 3 (BR3), B-cell maturation antigen (BCMA) and/or transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI), though BCMA and/or TACI can also bind to a proliferation-inducing ligand (APRIL). We evaluate the correlation of the expressions of these ligands/receptors with different clinical manifestations of systemic lupus erythematosus (SLE). Levels of BAFF and APRIL in plasma from 73 SLE patients were determined by enzyme-linked immunosorbent assay. Expressions of BR3, TACI and BCMA on CD19+ B cells were detected by flow cytometry. Clinical data were collected and disease activity was evaluated using SLEDAI-2000. SLE patients had elevated BAFF and APRIL levels in their plasma. BAFF levels correlated positively with SLEDAI while negatively with the BR3 protein expression on CD19+ B cells (p < .05). The detected BR3 protein expression in SLE patients was reduced on CD19+IgD+CD27-, CD19+IgD+CD27+ as well as CD19+IgD-CD27+ B cells compared to the counterparts of healthy controls (p < .001), whereas SLE patients did not differ from healthy controls in BR3 mRNA levels. In untreated new-onset patients, the expression rate of BR3 on CD19+ B cells correlated negatively with SLEDAI (p < .05). Elevation of BAFF and reduction of BR3 on CD19+ B cells were more obvious in those with lupus nephritis (LN, p < .05). TACI expression on CD19+ B cells was up-regulated only in those subjects with LN (p < .05). Elevated plasma BAFF and reduced BR3 protein expression on peripheral B cells could act as biomarkers for active disease in SLE patients. High expression of TACI may indicate the occurrence of LN.

Abstract
Desert beetle Microdera punctipennis (Coleoptera: Tenebriondae) is a special species in Gurbantonggut Desert in Central Asia. To investigate the possible strategy it employs for cold survival, seasonal changes in supercooling point (SCP), body water content, haemolymph osmolality and antifreeze protein gene (Mpafp) expression were measured over 13 months. Our results show SCPs in M. punctipennis adults changed from -8.0°C in summer to -18.7°C in winter. During winter, adults endured modest water loss; total water decreased from 65.4 percent in summer to 55.9% in winter. Mpafp mRNAs level increased by 13.1 fold from summer to early winter, and haemolymph osmolality increased accordingly from 550 mOsm to 1486 mOsm. Correlation coefficient of Mpafp mRNAs level and SCP indicates that Mpafp mRNA explained 65.3 percent of the variation in SCPs. The correlation between Mpafp mRNA level and total water reflected an indirect influence of antifreeze protein on water content via reducing SCP.

Abstract
The imbalanced superfluid state of spin- 1/2 fermions with s-wave pairing is numerically studied by solving the Bogoliubov-de Gennes equation at zero temperature in an annular disk geometry with narrow radial width. Two distinct types of systems are considered. The first case may be relevant to heavy fermion superconductors, where magnetic field causes spin imbalance via Zeeman interaction and the system is studied in a grand canonical ensemble. As the magnetic field increases, the system is transformed from the uniform superfluid state to the Fulde-Ferrell-Larkin-Ovchinnikov state, and finally to the spin polarized normal state. The second case may be relevant to cold fermionic systems, where the number of fermions of each species is fixed as in a canonical ensemble. In this case, the ground state depends on the pairing strength. For weak pairing, the order parameter exhibits a periodic domain wall lattice pattern with a localized spin distribution at low spin imbalance, and a sinusoidally modulated pattern with extended spin distribution at high spin imbalance. For strong pairing, the phase separation between the superfluid state and polarized normal state is found to be preferable, while the increase of spin imbalance simply changes the ratio between them.

Abstract
Neuropsychiatric (NP) events are severe manifestations of systemic lupus erythematosus (SLE) and relate to poor outcome. The aims of this study are to investigate the NP manifestations of SLE and to identify the predictive factors for clinical outcome. There was a retrospective review of 240 hospital patients with primary NP events of SLE (NPSLE) from 1990 to 2004. Neuropsychiatric manifestations, SLE disease activity index (SLEDAI) score, System lupus International Collaborating Clinic/American College of Rheumatology Damage Index (SLICC/ACR-DI) score, magnetic resonance imaging (MRI) findings, treatment and mortality rate were included for analysis. From this group of patients, 15 NP syndromes were identified. The most frequent manifestation was headache, followed by seizure. The mean SLEDAI and SLICC/ACR-DI scores were 19.9 +/- 6.9 and 3.5 +/- 1.6, respectively. Abnormal MRI features were found in 67% (61/91) patients. At least one intrathecal (IT) injection of methotrexate (MTX) plus dexamethasone (DXM) was administered to 109 (45.4%) patients. High dose (1 g) intravenous methylprednisolone pulse therapy (IVMP) was administered to 167 (69.5%) patients. Multifactor analysis revealed that high SLICC/ACR-DI scores and sets of concurrent NP symptoms were independently associated with poor outcome, whereas pulse IVMP and IT injection of MTX plus DXM were protective factors against poor outcome. From our data, NPSLE is heterogeneous and is usually associated with high disease activity and organ damage scores. High SLICC/ACR-DI score and having more than two sets of NP symptoms are the predictors for poor outcome, whereas pulse IVMP and IT injection of MTX plus DXM can improve the prognosis.

Abstract
OBJECTIVE Antimitochondrial antibodies (AMA) are the hallmark in primary biliary cirrhosis (PBC); nevertheless, it has long been recognized that 5-10% patients with typical features compatible with PBC do not have detectable AMA, and they were referred to as 'AMA-negative PBC'. This study aimed to evaluate whether AMA-negative/positive PBC represents different clinical entities. METHODS We compared the clinical, laboratory, percentage of regulatory T cells (Tregs) in peripheral blood, liver biopsy features and response to treatment of the two groups of patients. The first group was comprised of 12 patients with 'AMA-negative PBC'. The second was made up of another 12 PBC patients with positive AMA. RESULTS Antimitochondrial antibodies-negative/positive patients were remarkably similar in terms of clinical manifestations, liver biochemistries and histological findings. The frequency of anti-nuclear antibodies, anti-smooth-muscle antibody, anti-gp210 and anti-sp100 antibody showed no significant difference between the two groups. A significantly lower mean percentage of CD4+CD25(high) T cells was observed in peripheral blood mononuclear cells of AMA-negative/positive PBC patients compared with that of the 12 control subjects (5.8+/-1.8 and 5.4+/-1.4% vs. 7.6+/-1.7% respectively; P=0.014 and 0.004). However, no difference could be found between AMA-negative and AMA-positive PBC patients (P=0.599). After 1 year treatment with ursodeoxycholic acid, the two groups showed similar response. CONCLUSION Antimitochondrial antibody-negative/positive PBC patients are similar in clinical, laboratory, percentage of Treg in peripheral blood, liver biopsy features and response to treatment. This suggests that AMA-negative PBC may be a variant of AMA-positive PBC rather than a separate clinical entity.

Abstract
We use an extended t-J model to study a single hole bound to a Na+ acceptor in Ca2-xNaxCuO2Cl2. For parameters suitable to cuprates, the ground state has a twofold degeneracy, corresponding to even (odd) reflection symmetry around the x (y) axes. The conductance pattern of the broken symmetry state is anisotropic as the tip of a tunneling microscope scans above the Cu-O-Cu bonds along the x (y) axes. This anisotropy is pronounced at lower voltages but reduced at higher voltages. Our theory agrees qualitatively with recent data of scanning tunneling microscopy showing broken local rotational symmetry.

Abstract
Layered organic superconductors are on the verge of the Mott insulator. We use the Gutzwiller variational method to study a two-dimensional Hubbard model including a spin exchange coupling term as a minimal model for the compounds. The ground state is found to be a Gossamer superconductor at small on-site Coulomb repulsion U and an antiferromagnetic Mott insulator at large U, separated by a first order phase transition. Our theory is qualitatively consistent with major experiments reported in organic superconductors.

Abstract
Gutzwiller variational method is applied to an effective two-dimensional Hubbard model to examine the recently proposed gossamer superconductor by Laughlin (LANL cond-mat/0209269). The ground state at half filled electron density is a gossamer superconductor for smaller intrasite Coulomb repulsion U and a Mott insulator for larger U. The gossamer superconducting state is similar to the resonating valence bond superconducting state, except that the chemical potential is approximately pinned at the mid of the two Hubbard bands away from the half filled.

Abstract
High-spin systems with orbital degeneracy are studied in the large spin limit. In the absence of Hund's coupling, the classical spin model is mapped onto disconnected orbital systems with spins up and down, respectively. The ground state of the isotropic model is an orbital valence bond state where each bond is an orbital singlet with parallel spins, and neighboring bonds interact antiferromagnetically. Possible relevance to the transition metal oxides is discussed.

Abstract
We show that the recently proposed S = 2 bond model with orbital degrees of freedom for insulating V2O3 not only explains the anomalous magnetic ordering but also other mysteries of the magnetic phase transition. The model contains an additional orbital degree of freedom that exhibits a zero temperature quantum phase transition in the Ising universality class.

Abstract
Fetal iodine deficiency disorder (FIDD) is the principal form of endemic cretinism, and the most common cause of preventable mental deficiency in the world. However not everyone at risk develops FIDD and familial aggregation is common. This suggests that genetic factors may also be involved. The Apolipoprotein E (APOE) gene encodes for a lipoprotein that possesses a thyroid hormone binding domain, and APOE genotype may affect the efficiency with which thyroid hormone influences neuronal cell growth during the first and second trimesters of fetal development. We have compared ApoE genotypes in 91 FIDD cases with 154 local control subjects, recruited from three iodine deficiency areas in central China. We have also genotyped 42 FIDD family cases and 158 normal individuals from the families of local controls, and 375 population controls from Shanghai. APOE epsilon4 genotypes were significantly enriched in FIDD probands from each of the three iodine deficiency areas; the epsilon4 allele frequency was 16% vs 6% in controls. The same effect was also observed when we compared FIDD family cases with controls and control families. Our data suggest that in iodine-deficient areas, the APOE epsilon4 allele is a genetic risk factor for FIDD. The phenomenon may affect population selection and contribute to the low frequency of the epsilon4 allele in Chinese compared to Caucasian populations.

Abstract
Human chorionic gonadotropin (hCG) has been considered as a primary target molecule for a contraceptive vaccine by the World Health Organization because of its physiological and temporal specificity. hCG is an essential factor for the successful implantation and establishment of early pregnancy. For a decade, the most advanced works in development of a contraceptive vaccine have been concentrated on polypeptide based vaccines targeted directly against hCG. Although many studies have reached the stage of clinical testing using a number of prototype vaccines based on different parts of hCG molecule, their efficacy has been disappointing (1-4).

Abstract
The amino acid sequence of purified rabbit blastocyst peptide2 (RBP2) was analyzed. It contains 54 amino acids and it's sequence from aa4 to aa34 is the same as the N-terminal sequence of uteroglobin. An active antigenic region consisting of 15 aa residues (aa20-aa34) of the RBP2 was selected and designated as a synthetic peptide fragment (SPF). The effect of SPF on lymphocyte proliferation was analyzed by immunocytochemical assay detecting BrdU incorporation in the cellular DNA. The results indicated that no obvious inhibitory effect of SPF on T cell proliferation at concentrations ranging from 80 to 320 micrograms/ml was observed, while RBP2 at the concentrations ranging from 20 to 160 micrograms/ml had a significant effect in a dose dependent manner, suggesting that the immuno-suppressive effect of SPF is less than that of RBP2. We have also observed that SPF at concentrations ranging from 45 to 180 micrograms/ml inhibited PGF2 alpha secretion in a dose dependent manner. On the other hand, the 3H-leucine incorporation of rabbit endometrium was enhanced by SPF (180 micrograms/ml) and this action was blocked by addition of protein inhibitory agent, actidine.

Abstract
Anti-Ro (or SSA) is a clinically important autoantibody that is found in 25-40% of patients with systemic lupus erythematosus as well as an even greater proportion of patients with Sjögren's syndrome or subacute cutaneous lupus. We have studied the binding of anti-Ro sera to multiple antigenic peptides constructed from the sequence of the 60-kD Ro molecule. The results demonstrate that sera bind these peptides in solid-phase assay. Surprisingly, some of these peptides also form a precipitin line in double immunodiffusion with anti-Ro sera. Formation of lines of identity in double immunodiffusion as well as absorption studies indicate that peptides distant in the primary amino acid sequence and without shared sequence are bound by the same antibody. In addition, data from surface plasmon resonance demonstrate that peptides identified in this manner have protein-protein interactions. Thus, these techniques may identify the components of conformational epitopes.
