This study presented our experience in the treatment of testicular torsion, which may help achieve early diagnosis and improve therapeutic effects. A retrospective analysis was conducted in 71 patients with testicular torsion who were treated in our hospital from October 2007 to April 2011. The age of the patients ranged from 16 days to 34 years. All the patients had unilateral testicular torsion, which took place on the left side in 43 cases and on the right side in 28 cases. The course of the disease varied between three hours to 30 days. Post-operative follow-up was conducted until October 2011. Items examined included signs and symptoms at their first clinical visit, ultrasound findings, treatment in emergency surgery, and post-operative follow-up. In this study, the 71 patients were diagnosed with testicular torsion by color Doppler sonography, 7 had testicular fixation, 63 patients received orchiectomy, while 1 patient did not undergo surgery due to pressure from family members. Post-operative follow-up showed that the one patient's testicle, which had been reserved, atrophied, while all the other survived. No recurrence was found during the follow-up visits. It is concluded that an early diagnosis and surgery is important in improving the survival rate of testicular torsion, and the diagnosis and treatment by the first attending clinician is of critical importance.

OBJECTIVETo reveal the sequence variations of the full coding region of the human alpha (1,beta/1,4) fucosyltransferase 5 gene (FUT5) in a Chinese Han population.

METHODSThe whole coding region of the FUT5 gene was amplified and sequenced in a total of 30 unrelated Chinese Han individuals. The PCR products containing the nucleotide variants observed in the study were subcloned into plasmid pcDNA to determine all potential haplotypes in the investigated population. Genetic polymorphisms of C560T (rs778970) and C484A loci were further analyzed by polymerase chain reaction-restriction fragment length polymorphism(PCR-RLFP) method.

RESULTSIn addition to seven previously reported base substitutions, two novel polymorphisms, namely C484A (Leu162Met) and T684C, were found in the coding region of the FUT5 gene in the 30 individuals. Seven haplotypes were identified by subcloning the variants into plasmid and subsequent DNA sequencing. The allele frequencies in the rs778970 locus in 160 Chinese Han individuals was 0.3031 for 560C and 0.6969 for 560T, while no polymorphism was detected in the C484A locus.

CONCLUSIONThe sequence of the coding region in the human FUT5 gene demonstrated high genetic diversity, and the allelic distribution of the rs778970 locus in the Chinese populations is polymorphic.

OBJECTIVETo investigate the expression of occludin, ZO-1, MMP-2, and MMP-9 in cerebral microvasculature following Pulse Electromagnetic Field (PEMF) induced BBB permeability change.

METHODSSprague-Dawley rats were randomized into PEMF and sham exposed groups (n = 8). After exposure to PEMF at 0.5, 1, 3, 6, and 12 h, BBB permeability was measured by Evans-Blue extravasation. The expression of occludin, ZO-1, MMP-2, and MMP-9 were detected by real-time quantitative reverse transcriptase PCR and western blotting. MMP-2 and MMP-9 activity were detected by EnzChek gelatinase assay.

RESULTSCompared with the sham group, PEMF exposure led to increased permeability of the BBB to EB, which was prolonged after exposure. BBB permeability became progressively more severe, and recovered at 6 h. The gene and protein expression of occludin and ZO-1 were significantly decreased, while MMP-2 and MMP-9 expression were significantly increased after exposure to PEMF. All levels of expression recovered 12 h following PEMF.

CONCLUSIONChanges to BBB permeability were related to the alteration expression of tight junction proteins and matrix metalloproteinase after exposure to PEMF.

BACKGROUNDParkinson's disease (PD) is an autosomally inherited neurodegenerative disease in elderly people. The etiology of PD has long been thought to be associated with both genetic and environmental factors. To explore potential genetic risk factors for PD in the northern Han Chinese population, we investigated three single nucleotide polymorphisms (SNPs) (rs4538475, rs11107 and rs12564040) in the BST1, PARK15 and PARK9 genes.

METHODSGenomic DNA from 215 PD patients and 212 matched controls was amplified in two independent PCR systems and subsequently genotyped by digestion with the endonuclease PstI. Genetic parameter and association studies were carried out with SPSS 13.0 and PLINK 1.07 software.

RESULTSWe could accurately detect all genotypes in the three loci with the PCR-RFLP or mismatched PCR-RFLP techniques. The observed heterozygosities of the rs4538475 and rs11107 loci in PD and control groups ranged from 0.460 - 0.481 and 0.410 - 0.441, in BST1, PARK15 respectively, while we detected no heterozygosity at the rs12564040 locus in PARK9. The similar distributions of genotypic frequency between both groups suggest that the three SNPs investigated in this study are unlikely to play roles as common risk factors or pathogenic mutations for PD in northern Han Chinese.

CONCLUSIONThe SNPs investigated in the BST1, PARK15 and PARK9 genes associated with PD susceptibility are not associated with PD in the northern Han Chinese population.

OBJECTIVETo evaluate the association between severity of obstructive sleep apnea hypopnea syndrome (OSAHS) without chronic kidney disease (CKD) and serum cystatin C.

METHODSA total of 238 patients with snoring during sleep admitted between January 2012 and June 2015 underwent full-night polysomnography for diagnosis of OSAHS. The patients were divided according to the apnea-hypopnea index (AHI) scores into simple snoring group (AHI<5) and mild (AHI, 5-15), moderate (AHI, 15-30), and severe OSAHS (AHI>30) groups. The medical history, baseline demographic characteristics, blood glucose, blood lipids, peripheral blood cell count and serum cystatin C were measured, and the correlation between polysomnographic parameters and serum cystatin C were analyzed in different groups.

RESULTSThe simple snoring, mild, moderate, and severe OSAHS groups consisted of 41, 49, 56, and 92 cases, respectively. Serum cystatin C, WBC and its subtype counts, RBC count, and superoxide dismutase (SOD) were all significantly higher in severe OSAHS group than in the other 3 groups (P<0.05), but serum creatinine and estimated glomerular filtration rate were comparable among the groups (P>0.05). Linear correlation analysis revealed that serum cystatin C was positively correlated with gender, BMI, neck circumference, abdominal circumference, SBP, AHI, and WBC (P<0.01) and inversely correlated with the average pulse oxygen saturation (ASpO2), minimum pulse oxygen saturation (MSpO(2)), and SOD (P<0.01). Multiple regression analysis identified AHI and SOD as independent factors that were positively and inversely correlated with serum cystatin C (β=0.218, P<0.010; β=-0.217, P<0.009), respectively.

CONCLUSIONSevere OSAHS is closely correlated with serum cystatin C, WBC, and SOD, suggesting that severe OSAHS may initiate the pathological process of early renal damage possibly in association with chronic intermittent hypoxia-induced oxidative stress and the initiation of the inflammatory cascade.
