As a connecting bridge between innate immunity and specific immunity,the Toll-like receptors (TLRs) play a significant role in inflammation,cellular signal transduction,and cell apoptosis.TLRs are also essential factors participating in immune regulation and immune escape in the pathogenesis and development of malignant tumors.A large number of clinical and experimental research have shown that the abnormal expression of TLRs can be detected in adenocarcinoma,such as lung cancer,breast cancer and colon caner.In recent years,the relationship between gynecologic malignant tumor and TLRs has received great interest.This article will review and summarize research progress of TLRs in ovarian cancer,cervical cancer,and endometrial neoplasia.

Objective To perform mutation screening on the OTOF gene of 76 Chinese patients with sporadic auditory neuropathy for investigating whether the patients contained mutational hotspots in the OTOF gene,identifying the distribution and frequencies of OTOF mutations,and detecting new mutation points in the OTOF gene.Methods Genemic DNA samples were extracted from peripheral venous blood samples of the patients.9 primer pairs were designed using the Primer 5.0 software package for 9 exons of the OTOF gene,in which mutations had been discovered in the past.The exons were amplified using polymerase chain reaction(PCR),and direct sequencing of the PCR products was performed to detect OTOF mutations.For analysing the sequence data,the DNAStar 5.0 software package was used.Results 8 types of OTOF polymorphic alleles were discovered in this study.Among them,the 82 769delAG deletion mutation was only found in a patient diagnosed with temperature sensitive auditory neuropathy.In exon 25 of this patient's OTOF gene,the AG deletion mutation caused the replacement of amino acid at positions 993~999 and resulted in a truncated protein at position 1 000 amino acid(exon 26),which caused an early stop codon.(This protein has 1997 amino acids in all).Nevertheless,no other mutations were found in this patient's OTOF gene.The heterozygous 76 378C/T and 82 913G/A polymorphisms were single nucleotide polymorphisms(SNP) discovered in this study.Other SNP found were 56 842A/C,82 885C/A,and 92 905G/A,which had been already published by NCBI.In addition,92 995C/T and 96 888C/T were heterozygous mutations found in the exons,but did not cause the replacement of acid amino.Conclusion Eight SNPs were found in the OTOF gene of the Chinese patients in this study.However,mutations,which were previously identified in other ethnic origins in the literature,were not found in these patients.Thus,the result implied that the Chinese patients with auditory neuropathy may contain new OTOF mutations or other relevant disease-causing genes.

Objective To observe the diagnostic value of thinprep cytologic test(TCT) and Pap smear in cervical disease.Methods The cervix cytological examination 7600 women were divided into two groups.The TCT was applied to the observation group(3800 cases).The Pap smear was applied to the control group (3800 cases).Results The positive rate of cervical intraepithelial neoplasia was higher in the observation group(17.26%,656/3800)than that in the control group(12.24%,465/3800)(P<0.01).The coincident rate with histopathology was higher in the observation group(96.34%,632/656)than that in the control group(87.53%,407/465)(P<0.05).But the positive rate of trichomonad was not obviously significant between the two groups(P>0.05).Conclusion The TCT is better than Pap smear,which is worthy of being recommended in diagnosis of cervical disease.

Objective:To answer the question whether executive function(EF) deficits are specific to attention deficit hyperactivity disorder(ADHD) or whether such deficits are also associated with disruptive behavior disorders(DBD),including oppositional defiant disorder(ODD) and conductive disorder(CD).Methods:A total of 19 pure ADHD boys,19 ADHD + DBD boys and 19 normal controls(criteria of DSM-Ⅳ) were collected as our samples.The groups were matched by age(less than 6 months).The research instruments included Stroop color-word task,Rey complex figure test,digit span test, trail making test,tower of Hanoi and verbal fluency test.Results:The differences of IQs weren't significant among three groups.(1) Both pure ADHD group and ADHD+DBD group performed worse(P0.05).(2) Pure ADHD group also showed deficits in the aspects of errors of Stroop 2,time and errors of Stroop 3, word interference time;immediate memory structure score of Rey complex figure test;time and errors of number-letter part and shifting time of trail making test;total time and steps of completing tower of Hanoi.The differences were significant(P

Objective:To study the executive function(EF)characteristics in boys with attention deficit hyperactivity disorder(ADHD)comorbid learning disabilities(LD).Methods:A total of 22 pure ADHD boys,22 ADHD + LD boys and 22 normal controls(by criteria of DSM-Ⅳ)were collected as our samples.The groups were matched by ages(less than 6 months)and ADHD subtypes.The research instruments included the Stroop color-word task,Rey complex figure test,digit span test,trail making test,tower of Hanoi and verbal fluency test.Results:The differences of VIQ weren't significant among the three groups;pure ADHD and ADHD+LD groups had lower PIQ than the control group;ADHD+LD boys had lower IQ than the controls.The performance in the EF tests:(1)Both pure ADHD and ADHD+LD groups performed worse in the aspects of time of number-letter part and shifting time,the repeat response of verbal fluency,and the differences were significant.But the differences between ADHD and ADHD+LD weren't significant.(2)ADHD+LD group also showed deficits in the aspects of time and errors of Stroops 2 and 4,time of Stroop 4,word interference time,the immediate memory and delayed recalling detail score of Rey complex figure test,time of number trail making,error steps(rule violation)of Tow of Hanoi,and the differences were significant.(3)Both ADHD+LD and pure ADHD groups made more errors in the naming color of the color-word card(Stroop part 4),and ADHD+LD boys performed worse than pure ADHD boys.Conclusion:The findings support the hypothesis that ADHD is related to EF deficit,whether or not comorbid LD.ADHD+LD showed significant difference in the aspects of inhibition,working memory,set shifting and fluency as compared with normal group,ADHD+LD boys perform more poorly than the pure ADHD boys.It's plausible that both ADHD and LD are associated with deficits of executive function.

Aptamers are oligonucleotides or peptides those are able to bind tightly,by their specific three-dimensional shapes,to a variety of targets.Because of numerous merits ( high affinity,high specificity,small size,little immunogenicity,stable structures,and ease of synthesis),aptamers represent a valid alternative to antibodies and become a valuable research tool and show great application to fundamental research,drug selection and clinical diagnosis and therapy.The review describe the applications and the possible applications of aptamers in the diagnosis,treatment and pathogenesis of autoimmune diseases.

Objective To analyze types, mechanism and forensic identification for traumatic visual loss. Methods 109 cases of the evaluation for impairment and disability on traumatic visual loss were retrospectively analyzed, including interocular differences, anisometropia, left or right eye and the distributions of visual acuity, etc. Results The male-to-female ratio was 5.8:1, mainly 30~59 years of age. The ratio of monocular versus binocular injuries was 17.17:1. The ratio of left versus right injured eye was 1.39:1 in intentional injury cases. 115 eyes were injured, 83 of which were in low vision or blindness. 95 patients(87.16%) had large interocular differences( ≥ 3 lines). There were 9 patients with anisometropia from 2.25D to 6.00D and 23 patients with anisometropia larger than 6.00D. Conclusion Interocular differences and anisometropia are common in practice, which are not included in the expertise standard yet. Functional vision should be considered when developing the expertise standard.

Objective To explore the relationship between self- management and DOSE index for patients with chronic obstructive pulmonary disease (COPD). Methods The convenient sampling and Pearson correlation analysis was used in the study,a total of 81 patients was investigated with Self- Management Scale (SMS) for COPD patients and DOSE index. Results The relationship of symptom management and DOSE index for COPD patients was a positive correlation (r=0.259, P<0.05);with self- efficacy was a negative correlation(r=-0.288, P<0.05).But self- management, daily life management, emotion management and information management with DOSE index were no correlation (P>0.05). Conclusions Through health education, nurses should strengthen to effectively help patients manage symptoms, enhance self- efficacy, improve the patients′quality of life.

This study was aimed to detect the expression of c-Jun N-terminal kinase (JNK) in renal tissues of lupus nephritis (LN) mice with chronic graft-versus-host disease (cGVHD) and to investigate that LN could be intervened by fluvastatin at different doses through the inhibition of JNK expression.LN models with cGVHD in mice were established first,and then diseased mice were randomly divided into four groups:normal control,fluvastatin intervention at high-dose group (10 mg/kg),fluvastatin intervention at low-dose group (5 mg/kg) and models without treatment.After killing the mice sixteen weeks later,total urine protein of every mouse was determined by a Biuret colorimetric assay.The protein and mRNA levels of JNK and p-JNK in kidneys were measured by immunohistochemistry,Western blot and RT-PCR,respectively.Compared with normal control,otal urine protein,JNK and p-JNK expressions at both mRNA and protein levels were significantly increased in cGVHD group (P ＜0.01),but their expressions were suppressed by fluvastatin treatment (P ＜0.01).JNK may play an important role in the pathogenetic progress of LN in mice,and fluvastatin is able to prevent LN via inhibition of JNK expression in renal tissues in cGVHD mice.
