Abstract
Varicocele (VC) is a common cause of male infertility, but the molecular mechanisms involved in its pathogenesis are unknown. We investigated the impact of varicocelectomy (VCT) on proteome profiles in testicular tissues of rats with VC, and analysed associated target genes and signalling pathways. Sixty male rats with VC were divided into two groups: control (n = 30), and VCT (n = 30). Tissues were collected 4 weeks after sham or VCT surgery. Matrix-assisted laser desorption/ionisation time-of-flight/time-of-flight mass spectrometry (MALDI-TOF/TOF MS) was used to analyse the comparative proteome profiles. Kyoto Encyclopaedia of Genes and Genomes (KEGG) Orthology-Based Annotation System was used for bioinformatic analysis. Fifteen proteins were differentially expressed between control and VCT groups. These differentially expressed proteins are associated with several specific cellular processes associated with the pathogenesis of testicular growth arrest associated with VC. Furthermore, the evaluation by transmission electron micrograph showed that VCT could decrease apoptosis of spermatogenic cells in rats. Understanding such molecular pathways might provide physicians with a better insight into VC and with potential targets for treatment.

Abstract
Lipoprotein lipase (LPL) is a key enzyme in lipid metabolism. This study investigated LPL gene expression, LPL enzyme activity, and the correlation of each with intramuscular fat (IMF) in Chinese Guangxi san-huang (GXSH) and Arbor Acres (AA) chickens. The results showed that age and breed had significant effects on LPL expression and enzyme activity. Correlation analyses showed significant positive correlations between LPL expression levels and IMF contents in the breast and thigh tissues of both GXSH (r = 0.712, P = 0.001; r = 0.792, P < 0.001, respectively) and AA (r = 0.644, P < 0.001; r = 0.545, P < 0.001, respectively) chickens. The results also indicated a significant positive correlation between LPL enzyme activity and IMF contents in the breast and thigh tissues of both GXSH (r = 0.615, P = 0.001; r = 0.685, P < 0.001, respectively) and AA (r = 0.600, P = 0.001; r = 0.528, P = 0.003, respectively) chickens. The results indicated that the LPL gene was significantly correlated with IMF in these two breeds. The results presented here could contribute to knowledge of LPL mRNA developmental expression patterns and enzyme activity, and it could facilitate further research on the molecular mechanisms underlying IMF deposition in chickens.

Abstract
In the present study, the complete mitochondrial (mt) genome of Cyclemys dentata was determined using PCR reactions. The structural organization and gene order of C. dentata were equivalent to those of most other vertebrates. The mt genome was 16,489 bp in length, has rich A+T content, consisting of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a control region (D-loop). All protein-coding genes started with ATG, many genes have complete stop codons, except ND2, COX3, ND3, and cyt-b genes had incomplete stop codons of T. The light-strand replication origin (OL) of C. dentata might fold into a stable stem-loop secondary structure, and its loop had 2 nt less than that of the Cyclemys atripons OL sequence. The D-Loop of C. dentata contained a central domain (CD), 2 extended termination associated sequences (ETAS1, ETAS2) and 3 conserved sequence blocks (CSB1, CSB2, CSB3). The average length of 20 turtles' mt genomes was 16,692.5 bp, including 34.1% A, 27.0% T, 26.0% C and 12.9% G. The C. dentata mitochondrial genome could provide useful data for further studies on phylogenetics and conservation genetics of this species. The phylogenetic relationships of the family Geoemydidae were analyzed by maximum-likelihood (ML) and neighbor-joining (NJ) based on concatenated sequences of 13 protein-coding genes from 20 turtle species. The ML and NJ trees had homologous topologies. The results support the existing classification of the genera of Geoemydidae, that C. dentata was a sister species of C. atripons, Pyxidea nested in Cuora, and Chinemys was synonymous with Mauremys.

Abstract
This study was carried out to test the feasibility of enhancing embryo production in vivo and in vitro by immunoneutralisation against inhibin or follistatin. In Experiment 1, multi-parity buffaloes were assigned into three groups: High group (n=8), which received one primary (2mg) and two booster (1mg) vaccinations (28-day intervals) with a recombinant inhibin α subunit in 1 mL of white oil adjuvant; Low group (n=8), which received half that dose; and Control group (n=7), which received only adjuvant. Immunisation against inhibin stimulated development of ovarian follicles. Following superovulation and artificial insemination, inhibin-immunised buffaloes had more developing follicles than the Control buffaloes. The average number of embryos and unfertilised ova (4.5±0.6, n=6) in the High group was higher (P<0.05) than in the Control group (2.8±0.6, n=5) and was intermediate (4.1±0.7, n=7) in the Low group. The pooled number of transferable embryos of the High and Low groups (3.2±0.5, n=13) was also higher (P<0.05) than that (1.6±0.7, n=5) of the controls. The immunised groups also had higher plasma concentrations of activin, oestradiol and progesterone. In Experiment 2, the addition of anti-inhibin or anti-follistatin antibodies into buffalo oocyte IVM maturation medium significantly improved oocyte maturation and cleavage rates following parthenogenic activation. Treatment with anti-follistatin antibody also doubled the blastocyst yield from activated embryos. These results demonstrated that immunisation against inhibin stimulated follicular development, enhanced oocyte quality and maturation competence, yielded more and better embryos both in vivo and in vitro.

Abstract
AIMS Hereditary non-polyposis colorectal cancer, thyroid medullary carcinoma, breast/ovarian cancer and gastric cancer/breast cancer syndrome are encountered in surgery. Some gastric cancer/breast cancer syndrome may be the result of a CDH1 germline mutation. This is the first report of CDH1 germline mutations gastric cancer/breast cancer syndrome in Chinese patients. METHODS Peripheral blood from the proband, as well as, her first and second degree relatives was collected and CDH1 gene exon 1-16 mutations were screened. E-cadherin/beta-catenin proteins expression and histopathologic features were examined on gastric cancer/breast cancer tissues from the proband. RESULTS A C-->T nucleotide substitution at exon 13 (mRNA 2200 locus, Accession number NM-004360) was found. This was a transition from GCC-->GCT in DNA sequence (Ala154Ala). Diffuse-type gastric cancer and infiltrating ductal breast carcinoma were present. Both tumours preserved E-cadherin/beta-catenin expression immunohistochemically. CONCLUSIONS Familial cancer syndrome with diffuse-type gastric cancer/breast cancer proband in Chinese has a propensity of early onset during lifespan. No truncating or splice-site CDH1 mutations had been identified in this family. A silent nucleotide variation in exon 13 of the CDH1 gene may contribute to some forms of cancer susceptibility.

Abstract
Spontaneous plaque-forming cell, SPFC, is a new hemolytic effector of monocytes, which is generated 6 to 7 days after antigen unstimulation or stimulation in man. SPFC is also detected in rats. A significant concomitant response of the SPFC, in number of SPFC at the peak response around the rejection day, and histoincompatibility of allogeneic combinations in skin or heart allograft transplantation of rats was found. Peak number of SPFC (28,850 + 1,343/10(6) on day 6 in H-1 incompatible combination (ACI-Lewis) was higher than that (11,606 + 4,235/10(6)) on day 10 in H-1 compatible combination (F344-Lewis) (p less than 0.05, Student'st-test). The day of peak SPFC response in each experimental group was also concordant with the day of rejection. The OX42 monoclonal antibody against CR3 of leukocyte-adhesion molecules inhibited hemolysis of the SPFC. Since the erythrocyte is a ligand of CR3, it is likely that hemolysis of SPFC is mediated by the CR3 adhesion molecules. In conclusion, SPFC may be an immunologic indicator of allograft rejection in rats.

Abstract
Twenty one patients with bronchial adenoma, treated surgically in our hospital, include three different neoplasms: carcinoid, cylindroma and mucoepidermoid adenoma. In this series, clinical characteristics were: bronchial obstruction when the tumor protrudes into the lumen and infection, first in the bronchus (bronchitis or bronchiectasis) then in the parenchyma (acute, recurrent or chronic pneumonia, tension abscess). Ball-valve action of the tumor may result in lobar or segmental emphysema. Preoperatively, most of the patients had been misdiagnosed as bronchitis, carcinoma of lung, bronchiectasis or acute tension abscess. In our series, all the patients were alive in a follow up of 2-8 years. Yet one patient is living with local recurrence and distant metastasis. To our experience, pneumonia recurring in the same area of the lung, localized wheezing, with or without endocrine symptoms, lobar or segmental emphysema may suggest bronchial adenoma. Tomography and endoscopy are important for diagnosis. For the treatment, sleeve resection of the main bronchus was done in 2, bronchoplastic lobectomy in 7, lobectomy in 10, and pneumonectomy in 2. Sleeve resection of the main bronchus or bronchoplastic lobectomy is recommended as a reliable procedure for this disease.
