Neutrophil ( PMN) is the main immune effect cell of killing candida yeast cells .It can recognize different cellular components of candida through a variety of surface and intracellular pattern recognition receptors , phagocytose and/or form extracellular traps to capture candida yeast and mycelia , then kill them with oxidation or non-oxidation mechanism .It can also adjust innate immunity and adaptive immune response in candida infection by interaction with other immune cells .This article reviews recent progress of the multiple subsets of neutrophil , the mechanism of its recognizing and killing candida , and the interaction with other immune cells , to provide new perspectives for clinical therapy of candida infections .

Objective To investigate impaired fasting glucose(IFG)status of office worker and enterprise personnel in Shiji-azhuang area,for providing a basis for early prevention of diabetes mellitus.Methods The fasting blood glucose level of 109 083 of-fice workers and enterprise personnel in Shijiazhuang area were detected in physical examination in 2012.Results The people of IFG (fasting blood glucose 5.6-<7.0 mmol/L)accounted for 14.61% in all subjects,1 6.61% in men,10.23% in women.3.5 1%male of the 18-<21 years old group were IFG.With the increasing of age,the ratio of IFG people gradually rised to a peak of 30.44% at the age group of 71-<76,and then decreased a little.While the proportion of female with IFG was 1.55% at 18-<21 years old group,with the increasing of age,to the age group of 5 1 - < 56 reached the first peak 20.27%,then decreased at the 56-<61 age group.Rapidly rising again,up to 31.74% the second peak in 76-<81 age group,and then decreased a little.Conclu-sion The proportion of IFG in male is higher than that in female.The proportion of IFG increases with age,and reaches the peak in a certain age (over 70 years old),and then at a relatively stable level.

Objective To analyze the methods and effects for treating unstable posterior pelvic ring fracture combined with sacral nerve injury and further identify the relationships among the diagnostic methods,surgical approaches and clinical outcomes.Methods A total of 38 patients with posterior pelvic ring fracture combined with sacral plexus injury treated from January 2000 to January 2010 were enrolled in the study.There were 20 males and 18 females at an average age of 35 years (range,10 to 59 years).The causes of fractures included traffic injury in 20 patients,fall injury in 12,weighty object impingement injury in five,and stabbing injury in one.Classification of posterior pelvic ring fractures included fracture and dislocation of sacroiliac joints in eight patients,fracture of ilium wing in two and sacrum fracture in 28.According to the Denis typing of sacrum fractures,there was one patient with type Ⅰ fracture,14 with type Ⅱ fracture and 13 with type Ⅲ fracture.All 38 patients presented the decrease or loss of skin sensation around the lower extremities,perineal region and crissum.Simultaneously,30 patients suffered motor dysfunction of the lower extremities,while 20 patients had bladder and anus sphincter dysfunction or sexual disorder.Thirteen patients were suspected of sacral plexus avulsion and four of them were confirmed by myelography or MRI examination.All patients had at least one associated injury.The average ISS was 21.9 points ( range,9 to 47 points).Therapeutic methods were fracture reduction and fixation in the absence of nerve decompression for eight patients and nerve decompression for 30 patients including 26 patients being also managed by fracture reduction and fixation.Operation time ranged from 6 days to 6 months.The clinical outcomes were evaluated according to the British Medical Research Council (BMRC) evaluation criteria of sensation and movement function.Results Thirty-four patients were followed up for average 4.9 years ( range,1 to 10 years),during which their pelvis obtained stable recovery.The neurological outcome was excellent in two patients,good in four and unchanged in two in the nondecompression group and was excellent in 16 patients,good in nine and unchanged in one in the decompression group,with the decompression group superior to the non-decompression group ( P ＜ O.05 ).Conclusions For unstable posterior pelvic ring fracture combined with sacral nerve injury,nerve decompression and release combined with internal fixation can better improve the sacral nerve function and obtain good pelvic ring stability and is worth of clinical application.

OBJECTIVETo detect potential mutation in a family affected with congenital dyserythropoietic anemia type II (CDA II).

METHODSTargeted sequence capture and next-generation sequencing (NGS) were used to analyze the exons and exon-intron boundaries of the SEC23B gene in a clinically suspected CDA II patient. Genotypes of the relatives were validated by Sanger sequencing. Potential impact of amino acid substitution on the structure and function of SEC23B protein was predicted with MutationTaster and PolyPhen-2. The protein structure was predicted with SWISS-MODEL software.

RESULTSThe proband was found to harbor double heterozygous mutations of the SEC23B gene, c.1727T>C (p.F576S) and c.1831C>T (p.R611W), which resulted in amino acid substitutions p.F576S and p.R611W. Both mutations were confirmed by Sanger sequencing. The sister of the proband was found to have carried c.1727T>C (p.F576S), while her father and son have carried c.1831C>T (p.R611W) mutation. In addition, the proband was detected to have carried c.211C>T (p.R71X) of the HFE gene, which resulted in substitution of arginine by a stop codon. The impact of above mutations on the structure or function of protein was predicted to be harmful. Splenectomy and iron chelation therapy have achieved effective improvement of anemia and iron overload. Computer simulation suggested that the mutations have altered the 3D structure of the SEC23B protein.

CONCLUSIONThe novel compound mutations of c.1727T>C and c.1831C>T of the SEC23B gene probably underlie the CDA II in the family, and there is a strong correlation between the genotype and phenotype.
