Objective To study the association of peptidylarginine deiminase 4 (PADI4) (padi4_94 and padi4_104) genetic single nucleotide polymorphism (SNP) and rheumatoid arthritis (RA) susceptibility in Han population of Hebei province. Methods This hospital-based case-control study included 115 RA patients and 106 healthy controls. All the individuals were recruited from Han Hebei residents and were randomly selected. The genotype and allele frequencies of PADI4 gene polymorphisms (padi4_94 and padi4_104) were analyzed by PCR-DNA sequencing method. Results The distribution of padi4_94 and padi4_104 genotypes between the two groups was not significantly deviated from that expected by Hardy-Weinberg equilibrium (P>0.05). The combined effect of padi4_94 and padi4_104 SNPs was analyzed and three haplotypos (AA, AG and GG) were found but without GA haplotype. The genotype and allele distribution of padi4_94 and padi4_104 in the patients with RA was not significantly different from that in healthy controls,and the analysis of haplotypes revealed that no haplotypes were risk factors for RA. Conclusion In Han population of Hebei province, the SNPs of PADI4 (padi4_94 or/and padi4_104) is no associated with RA susceptibility. Therefore, it should not be regarded as a genetic risk factor for RA.

Objective To prospectively evaluate the value of diffusion-weighted imaging with background signal suppression (DWIBS) in the detection and diagnoses of metastatic cervical lymph nodes. Methods Twenty patients with head and neck squamous cell carcinomas underwent conventional MRI and DWIBS. The ADC values were measured and compared between metastatic and benign lymph nodes. The abilities of DWIBS and conventional MRI in the evaluation of metastatic cervical lymph nodes were compared. Results Conventional MRI demonstrated 101 lymph nodes, in which 58 were diagnosed as metastatic nodes. When MRI criteria were used for discrimination between metastatic and benign nodes, the obtained sensitivity, specificity, accuracy, positive and negative predictive value were 78% (47/60), 81%(44/54), 80% (91/114), 82% (47/57) and 77% (44/57), respectively. The mean ADC values of metastatic nodes (n =60) and benign nodes (n =54) were (0.945 ±0.122) × 10-3 mm2/s and (1. 210 ±0. 151 ) × 10-3 mm2/s ( t = - 10. 354 ,P <0. 01 ). When an ADC value of 1. 090 × 10 -3 mm2/s was used as the threshold for discrimination between metastatic and benign nodes, the obtained sensitivity, specificity,accuracy, positive and negative predictive value were 88% (53/60), 80% (43/54), 84% (96/114), 83%(53/64) and 86% (43/50), respectively. Conclusion DWIBS is helpful in diagnosing metastatic cervical lymph nodes of head and neck squamous cell carcinoma, and is superior to conventional MRI in their detection.

Objective To evaluate the movement function of the left ventricular short-axis with parameters (velocity, acceleration and relatively force) measured with improved anatomical M-mode ultrasound. Methods Sixteen patients with myocardial ischemia coronary heart disease who had taken percutaneous transluminal coronary intervention (PCI) were enrolled. All patients were divided into two groups: group A, single major vascular stenosis (n=8);group B, more major vascular stenosis (n=8). M-mode curves of short-axis sections at mitral valve level, papillary level and apical level were recorded, then the peak myocardial velocities, acceleration and force of the systolic phase, early-diastole phase and end-diastole phase were measured at the post processing station. Results The variety ranges of average velocity and acceleration of the three levels during systolic phase were higher than that during diastole phase. The changing rate of velocity and acceleration in group B was higher than that in group A. Conclusion The new parameters that are measured and calculated with anatomical M-mode ultrasound can reflect the movement functions of coronary heart disease patients taken PCI.

OBJECTIVETo discuss the treatment characteristics of secretory otitis media (SOM) in cleft palate children.
METHODSA total of 319 patients (524 ears) with SOM and cleft palate (3-14 years old) who accepted treatment were divided into experiment group A, group B, and group C according to effusion characteristics in the middle ear and tympanic pressure. Group A included 112 patients with serous effusion (198 ears). Group B included 162 patients with mucinous effusion (248 ears). Group C included 45 patients (78 ears) with negative pressure in the middle ear without effusion and an acoustic immittance. A total of 208 patients (246 ears) with SOM and tonsil and adenoid hypertrophy were divided into control group Al, group B1, and group Cl matched with the same effusion characteristics in the middle ear and tympanic pressure. Group A and Al accepted puncture in the tympanic cavity, group B and B1 accepted tympanostomy tubes, and group C and Cl accepted puncture in the tympanic cavity after palatoplasty, adenoidectomy, and tonsillectomy. All groups were treated with antibiotics and ear drops. Cure rate and recurrence rate between the experiment group and the control group were compared.
RESULTSThe control group had a better cure rate [93.09% (229/246)] than the experiment group [77.29% (405/524)] 12 months after treatment. The experiment group had a higher recurrence rate [14.57% (59/405)] than the control group [3.93% (9/229)]. Statistical differences were observed between the two groups (P<0.05). SOM with cleft palate initially had a low cure rate, and thus it was treated repeatedly for many times.
CONCLUSIONSOM with cleft palate is different from normal otitis media in terms of clinical manifestation, treatment, outcome, and prognosis. This case should be considered a special otitis media to be treated with special examination and therapy to obtain better results. Repeated puncture in the tympanic cavity and tympanostomy tubes for six months according to effusion characteristics are better treatment options for patients with SOM and cleft palate.
