Objective To investigate the application of the straight head-hanging test in the diagnosis of the benign paroxysmal positional vertigo (BPPV ) .Methods The clinical manifestations of 324 patients with benign paroxysmal positional vertigo treated in our department from July 2009 to April 2014 were retrospectively analyzed . All of the patients were tested by Dix -Hallpike and roll test first ,then the straight head-hanging test was carried out .Results Of the 324 cases ,53 cases(16 .36% ) had signs of simultaneous multiple canal involvement ,and 27 ca‐ses of them could be triggered the symptom of vertigo in the straight head -hanging test .In patients with single semicircular canal BPPV ,85 cases (26 .2% )were evoked vertigo with or without positional nystagmus by Dix -Hallpike tests and 120 cases (37 .04% )were triggered the symptom of vertigo with or without nystagmus through roll test ,another 66 cases(20 .37% ) were induced vertigo with or without nystagmus in the straight head-hanging test .66 patients with positive straight head-hanging test were rotated along the sagittal plane for repositional treat‐ment .When these patients were re-evaluated at one week and 3 months ,the total improvement were 86 .36% (57/66) and 83 .33% (55/66) ,respectively .Conclusion The straight head -hanging test can improve the diagnostic rate and it is especially helpful for the diagnosis of superior semicircular canal benign paroxysmal positional vertigo . In patients with a history of typical vertigo ,the straight head -hanging test should be performed if they showed negative Dix -Hallpike test and roll test.

The feasibility of partial tonsillectomy was reviewed. Compared with total tonsillectomy, partial tonsillectomy has the advantages of less postoperative pain, lower postoperative bleeding rate and faster recovery. Partial tonsillectomy has a potential for tonsil regrowth and its efficacy in treating sleep-disordered breathing in children is still controversial.

OBJECTIVE: To discuss the effect of age on hyoid movement and the openness of UES in swallowing process, and to investigate the correlation between hyoid movement and openness of UES. METHOD: The X-ray dynamic swallowing videofluoroscopy was performed on 100 healthy adult volunteers(20-74 years). They were divided into three groups: young (ages 20 to 45), middle-aged (45 to 65) and older (65 and up). Then the software Avidemux 2. 5 and Image J were used to measure the time and distance of hyoid movement, and the maximal opening of the UES in swallowing process. RESULT: The time of hyoid moving to the maximal displacement was delayed along with the ages, and there were significant differences among the three groups (P<. 05). The staying time of hyoid in the maximal displacement gradually shortened along with the ages, and there was significant difference between young and older group, so was the middle-aged and older group(P<0. 05). The maximum antedisplacement of hyoid decreased with age, and significant differences were found between young and the middle-aged group and between oung and older group (P<0. 05). The maximal degree of UES opening decreased with the increase of age, and significant difference was found between young and older group (P<0. 05). The upper displacement of hyoid was not related to UES opening(P>0. 05), however, the antedisplacement of hyoid had significant relation to UES opening in the three groups (P<0. 05). CONCLUSION In swallowing process, the time and space parameters of hyoid movement and the maximal degree of UES opening were related to age. There was significant difference between the antedisplacement of hyoid and the openness of UES (P<0. 05).

The main purpose of this paper was to review the role of the hyoid movement in the swallowing process and the effect of swallowing posture, age, gender, bolus properties on the hyoid movement. The displacement of the hyoid bone was divided into vertical and forward displacement. The vertical displacement of the hyoid bone contributes primarily to epiglottic and laryngeal closure, while the anterior displacement contributes primarily to opening of the UES. The dysphagia patients often experienced a reduction in hyoid bone displacement. Therefore, further research on the movement of the hyoid bone in the deglutition, especially the relationship between anterior displacement and UES opening is necessary.

Objective To study the ego identity,mental health and their relationship among students in athletes.Methods 110 students in athletes and 122 athletes in students were measured with identity status scale and athletes' symptom checklist.Results ①Students in athletes have higher "present serf-commitment" (5.09±1.07)and lower "crisis in the past"(2.19±1.12)than athletes in students.The two demonstrate the obvious difference on the distribution of identity status.The percentage of students in athletes obtaining A is lower than that of athletes in students ,while the percentage of students in athletes obtaining D and MD is higher. ②Comparing with the norm,students in athletes have higher level on the factors of sematizafion (1.98±0.42),compulsion (2.21±0.51),interpersonal sensitivity(2.09±0.53),depression (1.85±0.53),anxiety ( 2.47 ～0.58 ),paranoid (1.98±0.21),psychoticism (1.79±0.22) and total average marks (2.00±0.34),lower level on the factors of hostility (1.43±0.48)and cognitive(1.64±0.31). ③Three domains of ego identity exit obvious negative correlation with the sores of psychological symptoms.ANOVA confined that the more advanced ego identity is,the better mental health is.Conclusion Ego identity and mental health of students in athletes have their own features,and ego i-dentity will influence mental health.

Objective To evaluate the therapeutic efficacy and safety of micro-invasive craniopuncture scavenging technique (MPST) for treatment of intracranial hematoma in patients with hypertensive cerebral hemorrhage (HICH).Methods All the clinical randomized controlled trial (RCT) studies published on MPST and internal medicine conservative treatment of HICH were searched via computer screening of databases including Cochrane clinical trials database, the Chinese biomedical literature database (CBM), Chinese periodical network full-text special topic database, Chinese science and technology periodical database and electronic periodicals database of Wanfang from January 2006 to January 2017. The study group was given the MPST plus basic treatment, and the control group was given conservative treatment. The studies collected meeting the eligible criteria were sorted and analyzed by the software RevMan 5.0, the differences in therapeutic effect and mortality were compared between the two groups, and a funnel chart was plotted to analyze the potential publication bias.Results A total of 13 RCTs published studies consistent with the eligible criteria were found, including1556 patients. The Meta-analysis showed that the effective rate in the study group was significantly higher than that in the control group [odds ratio (OR) = 4.29, 95% confidence interval (95%CI) 3.33 - 5.53,P < 0.01]; the fatality rate was markedly lower than that of the control group (OR = 0.25, 95%CI 0.19 - 0.35,P < 0.01). The funnel graph showed that each study had asymmetrical scatter plot of the variable quantity of research results, indicating a publication bias being present, which might be related to the subjectivity of the researchers in publishing their results.Conclusions Using MPST to treat HICH can significantly improve the therapeutic efficiency and reduce deterioration rate. However, due to the low quality of clinical research, it is necessary to carry out rigorous andmulti-center randomized controlled studies to further confirm the results.
