Abstract
Rheumatic fever is an autoimmune disease characterized by recurring acute or chronic systemic connective tissue inflammation caused by group A streptococcal infection in the throat. Although rheumatic fever is common in China, there is a lack of standardized criteria for the diagnosis and treatment of this condition. Based on evidence and guidelines from China and other countries, the Chinese Rheumatology Association developed standardized criteria for the diagnosis and treatment of this disease in China. The aim was to standardize rheumatic fever diagnosis methods, treatment opportunities, and strategies for both short-and long-term treatment, so as to reduce irreversible damage and improve prognosis.

Abstract
Hepatocellular carcinoma (HCC) is one of the most lethal cancers globally. Hepatitis B virus (HBV) infection might cause chronic hepatitis and cirrhosis, leading to HCC. To screen prognostic genes and therapeutic targets for HCC by bioinformatics analysis and determine the mechanisms underlying HBV-related HCC, three high-throughput RNA-seq based raw datasets, namely GSE25599, GSE77509, and GSE94660, were obtained from the Gene Expression Omnibus database, and one RNA-seq raw dataset was acquired from The Cancer Genome Atlas (TCGA). Overall, 103 genes were up-regulated and 127 were down-regulated. A protein–protein interaction (PPI) network was established using Cytoscape software, and 12 pivotal genes were selected as hub genes. The 230 differentially expressed genes and 12 hub genes were subjected to functional and pathway enrichment analyses, and the results suggested that cell cycle, nuclear division, mitotic nuclear division, oocyte meiosis, retinol metabolism, and p53 signaling-related pathways play important roles in HBV-related HCC progression. Further, among the 12 hub genes, kinesin family member 11 (KIF11), TPX2 microtubule nucleation factor (TPX2), kinesin family member 20A (KIF20A), and cyclin B2 (CCNB2) were identified as independent prognostic genes by survival analysis and univariate and multivariate Cox regression analysis. These four genes showed higher expression levels in HCC than in normal tissue samples, as identified upon analyses with Oncomine. In addition, in comparison with normal tissues, the expression levels of KIF11, TPX2, KIF20A, and CCNB2 were higher in HBV-related HCC than in HCV-related HCC tissues. In conclusion, our results suggest that KIF11, TPX2, KIF20A, and CCNB2 might be involved in the carcinogenesis and development of HBV-related HCC. They can thus be used as independent prognostic genes and novel biomarkers for the diagnosis of HBV-related HCC and development of pertinent therapeutic strategies.

Abstract
At present, sexual route is the main transmission route of AIDS in China, and its role in the process of AIDS epidemic has been evolving. Various modes of transmission in sexual transmission and the prevention and control strategies adopted by China have also been changing. This paper mainly summarizes the epidemic characteristics of different periods and different modes of transmission of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in China in recent years. The strategies of prevention and control were described from seven aspects, including health education, promotion of condom use, expanded testing, HIV/AIDS antiviral treatment, pre-exposure prophylactic medication, post-exposure prophylactic medication, social organization participation and sexually transmitted diseases prevention and control. Only when innovative and targeted measures according to the evolution of the HIV/AIDS epidemic and various specific methods are complemented by each other, can the transmission of HIV/AIDS through sexual route be effectively prevented and controlled.

Abstract
Objective: To investigate the value of tumor perfusion parameter measured by using double contrast-enhanced ultrasound (DCEUS) QontraXt three-dimensional pseudocolor quantitative analysis to the therapeutic effect evaluation of preoperative neoadjuvant chemotherapy (NAC) in advanced gastric cancer (AGC) patients. Methods: Eighty-nine AGC patients underwent 3 cycles of preoperative NAC (XELOX) followed by complete resection of lesion. The DCEUS QontraXt three-dimensional pseudocolor was performed one or two weeks before the NAC and operation were applied, respectively. The peak enhancement (PE), time to peak (TP), sharpness of the bolus (β) and area under the enhancement curve (AUC) of primary gastric tumor were measured by QontraXt three-dimensional pseudocolor quantitative analysis. These DCEUS parameters between respond and non-respond groups before and after NAC therapy were compared. The prediction accuracy of DCEUS to the therapeutic effect evaluation of preoperative NAC was determined by the receive operating characteristic (ROC) curves. Results: Among 89 AGC patients, 52 patients responded to NAC therapy, while 37 patients resisted to NAC therapy. Twelve cases in respond group and 26 cases in non-respond group were mucinous carcinoma. Forty cases in respond group and 11 cases in non-respond group were non-mucinous carcinoma (P<0.05). In responder group, the PE and TP before NAC were (53.7±9.3)% and (14 521±2 667) ms, and (32.2±5.5)% and (17 235±1 898) ms after NAC. The ratio of changes of PE (ΔPE) and TP (ΔTP) were 0.43±0.17 and 0.36±0.14, respectively. In non-respond group, the PE and TP before NAC were (54.4±7.2)% and (13 869±3 247) ms, and (45.3±6.1)% and (15 127±1 423) ms after NAC therapy. The ratio of ΔPE and ΔTP were 0.24±0.20 and 0.22±0.12. The PE and TP after NAC, the ratio of ΔPE and ΔTP were significant different among these two groups (all of P<0.05). The ROC curves showed that the ratio of ΔPE in assessing the respond of gastric cancer patients to NAC was superior compared to other parameters (AUC=0.784, P=0.004). The optimal cut-off value of the ratio of ΔPE was 24% and its sensitivity and specificity to the therapeutic effect evaluation of NAC in gastric cancer were 82.7% and 64.9%. Conclusion: DCEUS QontraXt three-dimensional pseudocolor quantitative analysis might be a novel, noninvasive and reliable method to evaluate the therapeutic effect of preoperative NAC in AGC patients.

Abstract
Objective: To observe the effect of febuxostat on epithelial-to-mesenchymal transition (EMT) of kidney tubules and the levels of serum IL-6 nad transforming growth factor (TGF)β(1) in hyperuricemic rats. Methods: Forty male SD rats were divided into 4 groups: normal control group (NC group), oteracil potassium group (OP group), oteracil potassium with febuxostat group (OF group) and oteracil potassium with benzbromarone group (OB group). Each group had 10 rats and balanced in body weights. To induce hyperuricemia, rats were given oteracil potassium by gastric gavage once a day for eight weeks. Rats in OF group and OB group were given either febuxostat or benbromarone starting with oteracil potassium, and rats in NC group was given saline only. Blood samples were taken before, and at the end of 4 and 8 weeks of the treatments and serum uric acid, creatinine, blood usea nitrogen(BUN), IL-6 and TGFβ(1) contents were measured at each time point. Renal pathological changes were observed via HE and Masson staining, and the expression of α-SMA and E-cadherin were detected by immunohistochemistry. Results: Compared with those in NC group, the levels of serum uric acid, creatinine, BUN, IL-6 and TGFβ(1) in the another three groups were increased significantly (all P<0.01). However, the IL-6 and TGFβ(1) contents in OF group were much lower than those in OP group (P<0.01). HE and Masson staining showed that OF group had less damage and tubulointerstitial fibrosis than OP group and OB group (P<0.01). Moreover, the expression of α-SMA was significantly down-regulated (P<0.01) and that of E-cadherin was significantly up-regulated in OF group compared with those in OP group. Conclusion: Febuxostat treatment significantly inhibited EMT and reduced the levels of IL-6 and TGFβ(1) in hyperuricemia rats.

Abstract
AIM To investigate the function of miRNAs in odontoblast-like differentiation of human dental pulp cells (hDPCs). METHODOLOGY Integrated comparative miRNA microarray profiling was used to determine the differential miRNAs expression in odontoblast-like differentiation of hDPCs. The abundance of microRNA-135b (miR-135b) was measured by quantitative real-time reverse transcriptase polymerase chain reaction (qRT-PCR) and in situ hybridization (ISH). Bioinformatic analyses combined with luciferase assays were utilized to identify the targets interacting with miR-135b. Overexpression of miR-135b was performed to investigate the role and mechanism in odontoblast-like differentiation of hDPCs. Statistical analysis was performed by one-way analysis of variance (anova) or Student's t-test. RESULTS Thirty-six differentially expressed microRNAs in odontoblast-like differentiation of hDPCs were identified. MiR-135b expression was significantly downregulated during hDPCs differentiation (P < 0.05). In addition, miR-135b was able to bind to the 3'-UTR of the Smad5 and Smad4 and repressed these two genes expression (P < 0.05). Furthermore, overexpression of miR-135b suppressed odontoblast-like differentiation of hDPCs and attenuated the expression of Smad5 and Smad4 (P < 0.05). CONCLUSIONS These observations indicated a potential role of miR-135b in mediating odontoblast-like differentiation of hDPCs and inhibition of miR-135b might be a promising therapeutic way to facilitate dentine tissue engineering.

Abstract
Costello syndrome (CS; OMIM 218040) is caused by heterozygous germline mutations of HRAS (OMIM 190020).We report on a patient with sporadic CS presenting with characteristic craniofacial dysmorphism, congenital cardiopulmonary disorders, intellectual impairment, and skin abnormalities manifesting as loose redundant skin of the hands and feet, acanthosis nigricans, multiple naevi and hypotrichosis. Using Sanger sequencing for the case-parents trio, we detected a de novo insertion mutation (c.187_207dup) in HRAS, which was predicted to result in duplication of amino acids 63-69 (p.E63_D69dup). This mutation was recently described in a mild case of CS, with hyperactivation of HRAS and disrupted capacity to respond to incoming signals. Our study delineates the detailed clinical features associated with this noncanonical HRAS mutation and further expands the phenotypic spectrum of CS.

Abstract
Diffuse cutaneous mastocytosis (DCM) is an extremely rare disease characterized by massive proliferation of mast cells infiltrating the entire skin. We report a Chinese family with indolent DCM, and detection of a new germline KIT mutation located in the fifth immunoglobulin-like loop of the KIT protein, which probably results in a gain-of-function effect and consequent overactivation of mast cells. Our report expands the knowledge of correlations between the genotype of KIT mutations and the phenotype of DCM.

Abstract
BACKGROUND Alterations of the PTCH1 gene have been found to contribute to both familial and sporadic basal cell carcinoma (BCC), especially in Caucasian patients. Furthermore, the majority of PTCH1 gene mutations in sporadic BCCs in Caucasian patients carry ultraviolet (UV) signatures, suggesting the key role of UV light in BCC development. However, sporadic BCC in non-Caucasian population has a lower incidence, and the pathogenesis remains largely unknown. To date, there has been no mutation analysis on PTCH1 gene in Chinese patients with sporadic BCCs. OBJECTIVE To investigate genetic alterations of the PTCH1 gene in Chinese sporadic BCCs. METHODS Direct sequencing was used to screen for mutations in PTCH1 in 31 microdissected samples in Chinese sporadic BCCs. In addition, single nucleotide polymorphisms (SNPs) were studied for loss of heterozygosity (LOH). RESULTS Nineteen PTCH1 mutations in 17 of the 31 BCCs (54.8%) were identified. SNP analysis revealed LOH of PTCH1 in 10 of 23 BCCs (43.5%). Interestingly, the majority of mutations identified (63.2%) were insertion/deletion, which was different from the results in Caucasian cases whose mutations are predominantly point mutations. Only two (10.5%) of the remaining seven mutations were UV-specific C → T transition or tandem CC → TT transitions. All mutations occurred evenly throughout the entire PTCH1 protein domain without a hot-spot detected. CONCLUSION Mutations and LOH in PTCH1 were also highly prevalent in Chinese sporadic BCCs. However, UV light plays a less role in causing these mutations, suggesting other potential mechanisms in the development of sporadic BCC in Chinese patients.

Abstract
OBJECTIVE To investigate the prevalence of low back pain (LBP) and axial spondyloarthritis (SpA) in a Chinese Han population. METHODS A face-to-face investigation was performed in the Han population of Dalang Town, Yangshan County, Guangdong Province, China, using a questionnaire established in France in 1999. First the clinical features associated with SpA were investigated, then the human leucocyte antigen (HLA)-B27 and sacroiliac joint radiographic examinations were carried out. Finally, the diagnosis of SpA was determined by rheumatologists. RESULTS A total of 13 315 subjects participated in the study and 10 921 were aged >16 years; of these, 787 (7.21%) had LBP. There were 92 axial SpA patients (0.782% in subjects >16 years old and 11.96% in subjects with LBP). There were 29 (0.253%) cases of ankylosing spondylitis (AS), 60 (0.507%) undifferentiated axial SpA (USpA), and three (0.022%) psoriatic arthritis (PsA). Patients in the SpA groups had higher percentages in onset <40 years, insidious onset, morning stiffness, and affected for >3 months compared with those in other LBP groups. Simultaneous symptoms associated with spondylitis, such as buttock pain, heel pain, psoriasis, and SpA family history, were more commonly present. Of the axial SpA patients, 82.67% were HLA-B27 positive, clearly a greater percentage than those (11.65%) in other LBP groups. CONCLUSIONS The survey questionnaire for SpA in this study is useful for axial SpA screening in China. In southern China, the prevalence of LBP is 7.21%. The prevalence of axial SpA is 0.782%. USpA is the most common subtype of SpA, followed by AS.

Abstract
There are reports of IL-1 complex gene polymorphisms in ankylosing spondylitis (AS; MIM 106300), but the results have been inconsistent among populations. Moreover, few studies examine the association between IL-1 complex gene polymorphisms and clinical symptoms of AS patients. We investigated polymorphisms of IL-1 complex with AS in the Chinese Han population in this study. Chinese Han AS patients and ethnically matched healthy controls were genotyped for five single nucleotide polymorphisms (IL1beta+3953, beta-511, F10.3, RN.4, RN.6/1) and the IL1RN.VNTR of IL-1 gene cluster. Allele, Genotype and haplotype frequencies were compared between cases and controls by SHEsis software. The frequency of allele C of the marker IL1F10.3 was significantly increased in AS patients versus controls [p = 0.001, odds ratio (OR) = 1.54, 95% confidence interval (CI) = 1.19-1.20; p = 0.002, respectively]. Strong linkage disequilibrium was identified between IL1B-511, IL1B+3953 and RN4 in both patients and healthy controls (D' > 0.95). Haplotypes of pairs of these markers (6) were also significantly associated with AS. The strongest associations observed was between allele combination B-511-T/B+3953-C/F10.3-C/RN4-T/RN2VNTR-1/RN6.1-C and AS (p = 3.32 x 10(-5), OR = 4.41, 95% CI=2.1-9.3). Clinical manifestation showed week association between RN2VNTR A2 allele and risk of peripheral arthritis (OR = 0.2, 95% CI = 0.07-0.91). The IL-1 gene cluster is associated with AS in Chinese population. This finding provides strong statistical support for the previously observed relationship and indicates possible association between clinical manifestation and genetic factor.

Abstract
Netherton's syndrome is a rare autosomal recessive disorder caused by mutations of the SPINK5 gene, which encodes the lymphoepithelial Kazal-type-related inhibitor (LEKTI) protein. We observed microstructural changes and detected LEKTI activity and SPINK5 gene mutation in three Chinese patients with Netherton's syndrome. Decreased LEKTI activity was found in the skin of patients. Lamellar bodies and foci of electron-dense material were detected in the intercellular spaces of the stratum corneum. A novel homozygous splicing mutation of 1430+2 T-->G was found in the SPINK5 gene in one proband. No mutation was found in the other family.

Abstract
The interference press fit of a metallic one-piece acetabular cup employed for metal-on-metal hip resurfacing procedures was investigated experimentally under laboratory conditions in the present study, in particular regarding the cup deformation. Tests were carried out in cadavers as well as polyurethane foams of various grades with different elastic moduli to represent different cancellous bone qualities. The cadaver test was used to establish the most suitable configuration of the foam model representing realistic support and geometrical conditions at the pelvis. It was found that a spherical cavity, with two identical areas relieved on opposite sides, was capable of creating a two-point pinching action of the ischeal and ilial columns on the cup as the worst-case scenario. Furthermore, the cup deformation produced from such a two-point loading model with a grade 30 foam was similar to that measured from the cadaver test. Therefore, such a protocol was employed in subsequent experimental tests. For a given size of the outside diameter of the cup of 60 mm, the cup deflection was shown to be dependent largely on the cup wall thickness and the diametral interference between cup and prepared cavity at implantation. For a relatively thin cup with a wall thickness between 2.3 mm (equator) and 4 mm (pole) and with a modest nominal diametral interference of 1 mm, which corresponds to an actual interference of approximately 0.5 mm, the maximum diametral cup deflection (at the rim) was around 60 μm, compared with a diametral clearance of 80-120 μm between the femoral head and the acetabular cup, generally required for fluid-film lubrication and tribological performances. Stiffening of the cup, by both thickening and lateralizing by 1 mm, reduced the cup deformation to between 30 and 50 μm with actual diametral interferences between 0.5 and 1 mm.

Abstract
A complete interceptive action on pregnancy was shown after ig mifepristone (RU-486) 16 mg.kg-1 or epostane 96 mg.kg-1 on d 10 of pregnancy in rats. The ig ED50 (95% fiducial limits) of RU-486 when given alone and in combination with epostane 12 mg.kg-1 were found to be 7.8 (5.3-10.0) and 2.6 (2.0-3.3) mg.kg-1, respectively (P < 0.05), while those of epostane when given alone and in combination with RU-486 4 mg.kg-1 were 25.5 (19.4-33.6) and 5.6 (4.7-7.4) mg.kg-1, respectively (P < 0.05). An absorption promotor, sodium dodecyl sulfate 24 mg.kg-1 ig, when given in combination with RU-486 8 mg.kg-1 or epostane 24 mg.kg-1, induced complete interceptive action on pregnancy. Levels of plasma progesterone declined significantly when epostane 12 mg.kg-1 was given in combination with RU-486 4 mg.kg-1 as compared with epostane 12 mg.kg-1 alone (P < 0.05). Results showed that drug combination therapy was of benefit both to RU-486 and epostane in their interceptive actions.

Abstract
Epostane (Epo), a 3 beta-hydroxysteroid dehydrogenase inhibitor, interrupted pregnancy in rats, rhesus monkeys, and women. Epo concentrations in serum were determined by high performance liquid chromatography (HPLC) at 0.25, 0.5, 1, 2, 4, 8, 16, 32, and 48 h after intragastric Epo 96 mg.kg-1 in rabbits. The concentration-time curve exhibited a 2-compartment open model. The pharmacokinetic parameters were: T1/2ka 0.79 +/- 0.08 h, T1/2 alpha 0.96 +/- 0.08 h, T1/2 beta 6.6 +/- 1.5 h, Vc 14 +/- 3 ml.kg-1, AUC 12.0 +/- 1.9 micrograms.h.ml-1, Tmax 1.8 +/- 0.5 h, Cmax 3.3 +/- 0.5 microgram.ml-1. After rat copora luteum were incubated with hCG 10 IU.ml-1 and Epo 10 or 100 micrograms.ml-1 for 18 and 48 h, luteal cells showed various degrees of degeneration and progesterone production was significantly inhibited.

Abstract
A complete interceptive action on pregnancy was shown after ig epostane (Epo) 48 and 96 mg/kg on d 10 of pregnancy in rats. ED50 (95% fiducial limits) of Epo was 20.7 (16.3-26.3) mg/kg. Epo 48 mg/kg ig on d12, 14 and 16 of pregnancy lowered rat plasma progesterone concentrations (P less than 0.05) and plasma corticosterone on d 16 of pregnancy (P less than 0.05). Epo 35 mg/(kg.d) was given ig on d 50-54 of pregnancy in rhesus monkeys. Vaginal bleeding was seen in all of the 6 treated monkeys. Complete expulsions of fetal and placental materials occurred in 5 of the treated monkeys, among which 2 aborted on d 53 and the other 3 on d 54 of pregnancy. Plasma progesterone concentrations of the treated monkeys were lowered on d 52, 53 and 54 of pregnancy (P less than 0.05) and plasma estradiol on d 51, 52, 53, 54 and 55 (P less than 0.05), while there were no significant differences in plasma hydrocortisone. Epo may be a valuable supplement to the existing methods of female contraception.
