Objective:To define more information for familial hematuria by genetic screening in a pedigree with familial hematuria.Methods:This was a 4 generation pedigree included 20 family members. The clinical data and laboratory manifestations of the family members were reviewed and collected from medical records. Meanwhile, the peripheral blood samples of 11 family members of the pedigree were collected, and then DNA samples were extracted by salting out method for genetic analysis. For genetic analysis, firstly, three family members including the proband were selected for whole exome sequencing, and the genetic variations were screened according to the sequence variation interpretation guidelines from the American College of Medical Genetics and Genomics (ACMG) for diagnostic sequence interpretation. Then PCR and Sanger sequencing were used to verify the identified pathogenic variants in all family members in the pedigree.Results:In the pedigree, 6 female members had persistent hematuria. Among them, 2 died due to end-stage renal disease, 2 died due to non-renal diseases, and 2 maintained stable renal function. One of the two members with stable renal function was diagnosed as IgA nephropathy by renal biopsy. Moreover, diffuse basement membrane lesions were identified in her renal biopsy sample after the electron microscope examination, which resulted in the suspected diagnosis of Alport syndrome. Genetic testing in this pedigree revealed two novel mutations in COL4A4 gene (NM_000092), c.G446T:p.G149V in exon 7 and c.G1249A:p.G417R in exon 20. Conclusion:Two novel mutations of COL4A4 gene (c.G446T:p.G149V in exon 7 and c.G1249A:p.G417R in exon 20) in a hematuria pedigree are related with phenotype of familial hematuria.

Objective To investigate the possible mechanism of hypogammaglobuinemia caused by ketongenic diet (KD).Methods Thirty-six children with intractable epilepsy (IP) and seventeen age-matched healthy children were recruited in this study.The percentages of B cells at various stages of devel-opment and follicular helper T ( Tfh) cells were detected by flow cytometry.The plasma concentrations of IL-21 were determined by ELISA.Real-time quantitative PCR was performed to detect the expression of mam-malian target of rapamycin ( mTOR) , Blimp-1, Bcl-6 and IL-21 at mRNA level in CD4+T cells.Results mTOR at mRNA level was significantly down-regulated after KD treatment (P<0.05).The numbers of Tfh cells were positively correlated with the transcriptional level of mTOR (r=-0.691, P<0.05).Conclusion KD treatment might down-regulate Tfh and B cells through suppressing the expression of mTOR at mRNA level, suggesting a possible mechanism of hypogammaglobuinemia induced by KD treatment.

Objective To explore the impact of ketogenic diet (KD) on follicular helper T cells(TFH) in children with intractable epilepsy.Methods Thirty-three cases with intractable epilepsy were selected between Jul.2013 and Jan.2014 in Shenzhen Children's Hospital,19 boys and 14 girls; average age was 39.6 months,and seventeen age-matched healthy children who took a physical examination in the same hospital were assigned as the healthy control group.Blood samples were collected from the children with refractory epilepsy before and after 1 week of KD treatment.The proportions of the various stages of B cells and TFH cells were detected by flow cytometry.The plasma concentration of interleukin-21 (IL-21) was determined by enzyme-linked immunosorbent assay(ELISA),and realtime quantitative PCR(RT-PCR) was performed to detect the levels of peroxisome proliferator-activated receptor gamma (PPAR-γ),B-lymphocyte-induced maturation protein-1 (Blimp-1),B-cell lymphoma 6 (Bcl6) and IL-21 mRNA expression in CD4 + T cells.Results (1) The number of TFH cells in children with intractable epilepsy [(3.57 ± 0.58) ％] was remarkably decreased after KD treatment(P ＜ 0.01),while there were no difference between after KD treatment and healthy control group[(4.93 ±0.70)％ vs (5.03 ±0.63)％,P ＞0.05].(2) The levels of transcription factor Bcl6 expression after treatment were significantly decreased,while inhibitory factor Blimp-1 expression increased (P ＜ 0.05).(3)The plasma concentration of IL-21 had a trend to decrease (P ＞ 0.05),while there were no difference before and after KD treatment,and levels of IL-21 mRNA expressions in CD4 +T cells were significantly decreased after the treatment (8.28 × 10-3 ± 1.19 × 10-3 vs 1.72 × 10-2 ± 0.81 × 10-2,t =3.08,P ＜ 0.05).(4) There was no significant difference in CD27-IgD + B cells before and after KD treatment (P ＞ 0.05),CD27 + IgD + B cell and CD27-IgD-B cells had a trend to decrease after KD treatment(P ＞0.05),and CD27 + IgD-B cells and CD27 + IgD-CD38 high plasma cells were significantly decreased after KD treatment (P ＜ 0.05).(5) The number of TFH cells were correlated positively with the number of CD27 + IgD-B cells and CD27 + IgD-CD3g high plasma cells (r =0.785,0.745,P ＜ 0.05).(6) The levels of PPAR-γmRNA in CD4 + T cells expression were significantly up-regulated after KD treatment (3.49 × 10-3 ± 1.10 × 10-3 vs 2.28 ± 10-3 ± 1.30 × 10-3,t =3.41,P ＜0.05),and the number of TFH cells and PPAR-γgene expression was correlated negatively (r =-0.619,P ＜ 0.05).Conclusions KD might down regulate TFH cell number and function through inducing PPAR-γexpression and could inhibit B cell differentiation,which might be one of the factors for hypogammaglobuinemia by KD treatment.

Objective To explore the clinical characteristics of and surgical strategies for distal tibiofibular syndesmosis separation based on ankle axial CT scan.Methods From January 2009 to January 2016,63 patients with injury to the distal tibiofibular syndesmosis were treated.Their injuries were characterized according to the anatomic characteristics on their ankle axial CT scan images as pronation-extorsion type (28 cases),supination-extorsion type (11 cases) and abduction type (24 cases).Specific strategies of reduction and fixation depended on the specific characteristics of distal tibiofibular syndesmosis separation.After 12 months postoperatively,the reduction quality was assessed by Burwell-Charnley's radiological evaluation system and the function of ankle joint was assessed using American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score system.Results The patients were followed up for 6 to 48 months (average,19.3 months).Anatomical reduction was achieved in 19 cases,good reduction in 7 and fair reduction in 2 in the pronation-extorsion type,yielding an excellent to good rate of 92.8％;anatomical reduction was achieved in 6 cases,good reduction in 4 and fair reduction in one in the supination-extorsion type,yielding an excellent to good rate of 90.9％;anatomical reduction was achieved in 17 cases,good reduction in 6 and fair reduction in one in the abduction type,yielding an excellent to good rate of 95.8％.By the AOFAS system,the pronation-extorsion type scored 88.6 points,the supination-extorsion type 89.4 points and the abduction type 86.6 points.Conclusion In the treatment of distal tibiofibular syndesmosis separation,reduction and fixation strategies should depend on analysis of the characteristics on the ankle axial CT scan,so as to achieve positive outcomes.

To investigate the reliability and feasibility of human papillomavirus (HPV) DNA test in cervical scraping smears with polymerase chain reaction (PCR), 131 cases of cervical scraping specimens were collected, and the positive rates and accuracy of HPV infection were determined in normal subjects and cervical cancer patients. GP5+/GP6+ and E7 primer pairs designed for detecting HPV L1 and HPV type 16 E7 were tested in this study. Our results showed that positive rates of HPV DNA in normal population and cervical cancer patients were 32.99 % and 73.53 % respectively and there was significant difference between them (P＜0. 001). In normal subjects, detection rates of HPV DNA with GP5+/GP6+ and E7 primer pairs were 27.84 % and 16.49 % respectively, with statistically significant difference between them (P＞0.05). However the detection rates in cervical cancer patients were 38.24 % and 67.65 % for the two markers, with a significant difference found between them (P＜0.05). It is concluded that HPV DNA test with PCR for cervical scraping smears was feasible. GP5+/GP6+ primer pairs may be a useful probe to screen HPV infection in normal population, but they are not sensitive enough in cervical cancer patients. It is suggested that high risk type HPV DNA test was very useful in population with high risk of cervical cancer.

Objective To get knowledge of the molecular epidemiological characteristics of human derived Brucella isolated in Hohhot,and to provide experimental basis in guiding prevention and treatment of Brucella infection.Methods Twenty-seven Brucella isolates derived from patients in Affiliated Hospital of Inner Mongolian Medical University from 2013 to 2015 were identified by routine bacteriological methods and molecular methods.Multiple-locus variable number tandem repeats analysis (MLVA-16) was used to detect molecular typing and do cluster analysis.Sixteen virulent genes were detected and analyzed by polymerase chain reaction (PCR).Results Twenty-seven Brucella isolates were identified as Brucella melitensis (B.melitensis) by routine bacteriological methods and PCR.Out of them,six isolates were B.melitensis biovar 1,and twenty-one isolates were B.melitensis biovar 3.MLVA-16 analysis showed that seven genotypes were obtained from nine Brucella isolates,which showed significant difference in variable number of tandem repeats,which suggested that they originated from sporadic outbreak.Moreover,two isolates were clustered into the same clade,which suggested they were epidemiologically correlated and may be derived from the same origin.Sixteen virulent genes were detected in all of the twenty-seven isolates.Conclusions Brucella isolates from patients in Hohhot are mainly B.melitensis biovar 3 and B.melitensis biovar 1,and the distribution profile of multiple virulence genes is similar.Some isolates have showed epidemic correlation,and the epidemic mechanism should be further explored.
