Abstract
BACKGROUND AND PURPOSE SPG7 is one of the most common forms of autosomal recessive hereditary spastic paraplegia. The phenotype has been shown to be heterogeneous, varying from a complex spastic ataxia to pure spastic paraplegia or pure ataxia. The aim of this study was to clinically and genetically characterize patients with SPG7 in Norway. METHODS Six Norwegian families with a clinical diagnosis of hereditary spastic paraplegia were diagnosed with SPG7 through Sanger sequencing and whole-exome sequencing. Haplotypes were established to identify a possible founder mutation. All patients were thoroughly examined and the clinical and molecular findings are described. RESULTS The core phenotype was spastic paraparesis with ataxia, bladder disturbances and progressive external ophthalmoplegia. The variant p.H701P was identified in homozygous state in one family and in compound heterozygous state in three families. Haplotype analysis of seven surrounding single nucleotide polymorphisms supports that this variant resides on a founder haplotype. Four of the families were compound heterozygous for the previously well-described p.A510V variant. CONCLUSION SPG7 is a common subgroup of hereditary spinocerebellar disorders in Norway. The broad phenotype in the Norwegian SPG7 population illustrates the challenges with the traditional dichotomous classification of hereditary spinocerebellar disorders into hereditary spastic paraplegia or hereditary ataxia. A Norwegian founder mutation p.H701P was identified in four out of six families, making it a major cause of SPG7 in Norway.

Abstract
OBJECTIVE Many studies suggest that adenosine deaminase is a marker for tuberculous pericarditis, while controversy exists as to its diagnostic utility. This study aims to summarize the overall diagnostic performance of adenosine deaminase for tuberculous pericarditis through a meta-analysis. MATERIALS AND METHODS Literatures published before May 2015 were searched in PubMed and EMBASE. The data were retrieved and the sensitivity, specificity, positive/negative likelihood ratio (PLR/NLR), diagnostic odds ratio (DOR) of adenosine deaminase for diagnosing tuberculous pericarditis were pooled, and the summary receiver operating characteristic (SROC) curves were used to examine the overall performance of adenosine deaminase. RESULTS In total, 11 studies with 938 subjects were included in the meta-analysis. The summary estimates of adenosine deaminase for diagnosing tuberculous pericarditis were listed as follows: sensitivity of 0.90 (95% CI: 0.86-0.93), specificity of 0.86 (95% CI: 0.83-0.89), PLR of 5.90 (95% CI: 4.46-7.82), NLR of 0.15 (95% CI: 0.09-0.26), and DOR of 42.55 (95% CI: 21.51-84.18). The area under the SROC curve was 0.92, and the Q value was 0.85. No publication bias was identified. CONCLUSIONS Adenosine deaminase is a valuable marker with both high sensitivity and specificity in the diagnosis of tuberculous pericarditis. Nevertheless, the results of adenosine deaminase assays should be interpreted in combination with other test results and clinical characteristics of patients.

Abstract
Human terminal deoxynucleotidyl transferase (hTdT) is a DNA polymerase that functions to generate diversity in the adaptive immune system. Here, we focus on the function of naturally occurring single-nucleotide polymorphisms (SNPs) of hTdT to evaluate their role in genetic-generated immune variation. The data demonstrate that the genetic variations generated by the hTdT SNPs will vary the human immune repertoire and thus its responses. Human TdT catalyzes template-independent addition of nucleotides (N-additions) during coding joint formation in V(D)J recombination. Its activity is crucial to the diversity of the antigen receptors of B and T lymphocytes. We used in vitro polymerase assays and in vivo human cell V(D)J recombination assays to evaluate the activity and the N-addition levels of six natural (SNP) variants of hTdT. In vitro, the variants differed from wild-type hTdT in polymerization ability with four having significantly lower activity. In vivo, the presence of TdT varied both the efficiency of recombination and N-addition, with two variants generating coding joints with significantly fewer N-additions. Although likely heterozygous, individuals possessing these genetic changes may have less diverse B- and T-cell receptors that would particularly effect individuals prone to adaptive immune disorders, including autoimmunity.

Abstract
We demonstrate that an annulus of light whose polarization is linear at each point, but the plane of polarization gradually rotates by π radians can be used to generate Bessel-Poincaré beams. In any transverse plane this beam exhibits concentric rings of polarization singularities in the form of L-lines, where the polarization is purely linear. Although the L-lines are invisible in terms of light intensity variations, we present a simple way to visualize them as dark rings around a sharp peak of intensity in the beam center. To do this we use a segmented polarizer whose transmission axes are oriented differently in each segment. The radius of the first L-line is always smaller than the radius of the central disk of the zero-order Bessel beam that would be produced if the annulus were homogeneously polarized and had no phase circulation along it.

Abstract
OBJECTIVE To explore the effect of LRIG3 in the development of cervical squamous cell carcinoma. MATERIALS AND METHODS LRIG3 and epidermal growth factor receptor (EFGR) expressions were detected by immunohistochemistry. Western blot method was used to detect LRIG3 and EGFR protein expression at different time points. MTT, flow cytometry, and transwell chamber were adopted to examine the proliferation, apoptosis, and strength of invasion of Hela229 cell respectively. RESULTS During the process of normal cervix deteriorating into CIN and CSCC, LRIG3 expression gradually decreased, while EGFR increased. After the transfection of LRIG3 ASODN into cells, the amount of LRIG3 expression and the cell apoptosis rate both decreased gradually, EGFR protein expression and cell proliferation rate both increased (p < 0.05), other groups remained unchanged (p > 0.05). The cell migration ability in LRIG3 ASODN transfection group was stronger than that of other groups (p < 0.05). CONCLUSION LRIG3 plays an important role in Hela229 cell proliferation, apoptosis, and invasiveness.
