Abstract
By literature review and experience summary, some problems are found in conservative treatment of osteonecrosis of femoral head(ONFH): lacking in researches of natural history of ONFH, disunion in classfication and the standard of outcome evaluation, lacking in high-level-evidence study and standard of treatment methods. It is necessary to improve the study on natural history of ONFH, unify the classfications and the standard of outcome evaluations, normalize the treatment methods, and design impeccable multi-centre study for improving the effect of conservative treatment of ONFH.

Abstract
We attempted to identify significant pathway cross-talk in rheumatoid arthritis (RA) by the Monte Carlo cross-validation (MCCV) method. We therefore obtained and preprocessed the gene expression profile of RA. MCCV involves identifying differentially expressed genes (DEGs), identifying differential pathways (DPs), calculating the discriminating score (DS) of the pathway cross-talk, and random forest (RF) classification. We carried out 50 bootstrap iterations of MCCV to identify the key instances of pathway cross-talk involved in RA. We identified a total of 17 significant DEGs and 15 significant DPs by comparing RA samples and normal controls. We found the most significant difference between RA and the normal controls in the eIF4 and p70S6K signaling regulation pathway. Furthermore, we identified 10 instances of pathway cross-talk with the best classification performance for RA and normal controls, using the RF classification model. All of the top 10 pathway pairs involved cross-talk with eIF4 and p70S6K signaling regulation, and the other 10 pathways were immune-related. By MCCV, we identified one critical DP and 10 significant instances of pathway cross-talk in RA. We propose that the eIF4 and p70S6K signaling regulation pathway and the other significant instances of pathway cross-talk play key roles in the occurrence and development of RA, and are potential predictive and prognostic markers for RA.

Abstract
The relationship between occupational asbestos exposure and esophagus cancer (EC) is not fully understood. We performed a meta-analysis to quantitatively assess the association. We systematically searched databases of PubMed, EMBASE, and Web of Science for studies with quantitative estimates of asbestos exposure and EC mortality. Pooled standardized mortality ratios (SMRs) and their corresponding 95% confidence intervals (CIs) were calculated. Twenty cohort studies on EC and asbestos exposure were included in this meta-analysis. Overall, occupational exposure to asbestos was associated with an excess risk of EC (SMR = 1.24, 95% CI: 1.13-1.38, P < 0.001), with little evidence of heterogeneity among studies (I(2) = 0.0%, P = 0.682). Being male, exposure to chrysotile or mixed asbestos, working at textile industry, long study follow-up (≥20 years), Asia, Europe and America cohorts with larger cohort size (>500), and high-exposure group all contribute to significantly higher SMR. Publication bias was not detected (Egger's test P-value = 0.374). This meta-analysis suggested that occupational asbestos exposure might be associated with an increased risk of EC in male. High-exposure level of asbestos could contribute to significantly higher risk of EC mortality.

Abstract
Myostatin (MSTN) is an important member of the transforming growth factor-β (TGF-β) superfamily and is a muscle growth inhibitor. In the present study, we cloned the Chinese perch MSTN cDNA sequence and analyzed its expression patterns under various conditions. The MSTN full cDNA sequence was 3347 bp long, including an open-reading frame of 1131 bp, which encoded 376 amino acids. Sequence analysis demonstrated that the MSTN shared a highly conserved signal peptide, a TGF-β functional peptide, a hydrolytic site (RARR), and nine conservative cysteine residues with other members of the TGF-β superfamily. Sequence alignment and phylogenetic tree analyses indicated that the MSTN had a close relationship with teleostean fish, but they are far separated from mammals. Real-time polymerase chain reaction analysis revealed that the MSTN was strongly expressed in the skeletal muscle and heart tissues. Temporal expression analysis demonstrated that the MSTN gene was expressed in very low levels, from 20 to 90 dph (post-hatching development), and was at its highest level at 150 dph (P < 0.05). The fasting-re-feeding experiment showed that the expression of the MSTN gene was initially decreased in response to a single meal, after seven days of fasting, and subsequently increased significantly, and finally decreased back to its original level. Together, our results provided valuable knowledge regarding the regulation of MSTN gene expression in Chinese perch.

Abstract
Endostatin is a potent and specific antiangiogenic protein capable of inhibiting the growth of murine and xenotransplanted human tumors. Thus far, however, recombinant endostatin prepared from Escherichia coli is insoluble after purification and therefore inappropriate for clinical settings. A soluble form of endostatin is available from a yeast system with relatively low yield and high cost, which has made it difficult to produce endostatin in quantities sufficient for extensive clinical evaluation. In this study, we developed a protocol to generate soluble recombinant murine endostatin from E. coli at a yield of 150 mg/liter-culture and 99% purity. The in vivo antiangiogenic and antitumor activities of the soluble recombinant endostatin are equally as potent as those of the previously published insoluble form. A similar protocol may be used to produce soluble human endostatin.

Abstract
The DNA of the major capsid protein VP1 of the human polyomavirus JC virus (JCV), Taiwan-3 strain, was generated from the urine of an autoimmune disease patient by polymerase chain reaction (PRC). The VP1 DNA was cloned into a prokaryotic expression vector, pGEX-4T-1, for expression in E. coli. The nucleotide sequences and the deduced amino acid sequences were determined and compared with the JC virus prototype, Mad-1. Thirty nucleotides were different between these two strains. Six of the altered nucleotides affected amino acid coding and ten of them caused changes in endonuclease recognition sites. The recombinant VPI protein was purified and used to raise monospecific antiserum in rabbit. Recombinant JCV VP1 protein and its monospecific antiserum are important clinical reagents and could possibly be developed as a subunit vaccine and as a serological diagnostic antigen in the future. In addition, the region between amino acid residues 40 and 80 of JCV VP1 is predicted to be an antigenic epitope on the basis of its hydropathy plot and comparison with the VP1 sequences of SV40 and BK virus.

Abstract
The authors adopted an animal model to observe the pathogenic mechanism of steroid-induced avascular necrosis of the femoral head. Sixty-four white rabbits were divided into two groups: hydrocortisone acetate (8 mg/kg) was hypodermically given to 48 experimental animals and 0.32 mg/kg of normal saline to 16 rabbits for control. Two groups of animals were fed and kept in the same condition. The results showed that application of the steroid drug could produce fat degeneration and necrosis of osteocytes and fat embolism in the small blood vessels of the femoral head. The abnormal hypertrophied fat cells in the bone marrow compressed small veins in the femoral head resulting in blood stasis of the capillaries, thus growth and regeneration of the capillary were inhibited.
