Objective To analyze the characteristic and the clinical application of high -frequency stimulation ABR for the patients with unilateral sudden deafness .Methods 40 patients aged 17~45 with unilateral sudden deaf-ness(40 health ears ,subject group)and 20 normal volunteers (40 ears ,control group)were selected to receive high and low frequency stimulation ABRs and pure tone audiometry .Results There were no statistical differences be-tween subject group and control group in pure tone audiometry .The wave Ⅰlatency of high -frequency ABR was longer in the subject group than that in the control group(P<0 .001) .The abnormal rate of Ⅰ - Ⅴ interval between high and low frequency stimulation ABRs was 62 .5% (25/40) in the subject group ,and 5% (2/40) in the control group .There were statistical differences between the two groups (χ2 =29 .574 ,P<0 .001) .Conclusion The waveⅠlatency of high-frequency ABR was longer and the abnormal rate of Ⅰ - Ⅴ interval markedly increased in the health ear of patients with unilateral sudden deafness .This may suggest that the contralateral ear may have an ab-normal blood supply of the inner ear when single side sudden deafness happened .High frequency stimulation ABR can be used to detect the potential changes of contralateral ear before the hearing loss occurred .

In forensic case, the location diagnosis determination of drowning has been one of the most important and dififcult diagnosis. Then diatom test is considered to be a relatively reliable method for the diagnosis of drowning. According to community characteristics inferred from diatoms into the different water region has been credibility. The study of the diatoms in different waters identiifcation is reference to the determination of the body drowned into the water area. In this paper, the research progress of diatom relevant biological characteristics and test methods on review for forensic workers is related to the further research and reference case in practice.

Objective To observe the clinical efficacy of HMME-SDT therapy for the treatment of hypertrophic scar (HS) of rabbit ear.Methods 60 white rabbits were randomly divided into five groups.The model group and HMME-SDT treatment group were used to establish the models of hypertrophic scar in ears.Results The effect of HMME-SDT on the fibroblastic density in the hypertrophic scarring models was observed in rabbit ears.The HMME-SDT could lower the fibroblastic density,compared with the model group,with significant difference (P＜ 0.05).The effect of HMME-SDT on the collagen area density was noted in the hypertrophic scarring models in rabbit ears.The HMME-SDT could lower the collagen area density,compared with the model group,with significant difference from the fourth week of the epithelialization (P＜0.01).Conclusions HMME is an effective sonosensitizer.HMME-SDT can significantly inhibit hypertrophic scar of rabbit ear.

Objective To assess attitudes and its related factors of Chinese military personnel on homosexual served in the military.Methods 1362 enlisted military personnel,selected from land force by cluster sampiing,were interviewed by Military Personnel's Attitudes Toward Homosexuals in the Military Scale(ATHM).Results The attitudes of the present sample toward homosexual served in the military were found to be negative(the total score on the ATHM scale was (29.28 ± 6.59).The threat dimension made the biggest contribution to the negative attitude,followed by the comfort dimension.Marital status was negatively related to the total scores of ATHM (r =-0.067,P ＜ 0.05),and other demographic variables such as age,only child,nationality,childhood environment,education level,years of service,and military rank were not associated with attitudes toward homosexuals in the military (r =-0.01,0.002,-0.035,-0.041,-0.015,-0.041,-0.039,P ＞ 0.05).Further multiple linear regression analysis found that marital status was one of the attitudes' predictors.Conclusion Because of the threat and discomfort with homosexual,the attitudes toward homosexual in the military are mildly negative,and marital status correlate with it.

OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.

METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.

RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).

CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.

METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.

RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.

CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.

OBJECTIVETo investigate the role of transcription factor special AT-rich binding protein 2 (SATB2) in the osteoblasts differentiation of bone marrow stromal cells (BMSC) in vitro.

METHODSRats bone marrow stromal cells were isolated by Percoll sedimentation and the cells were placed and allowed to attach for three times. After passages, expression plasmid pBABE-hygro-satb2 was constructed, then transfected into BMSC. BMSCs were inoculated in conditioned medium and osteogenic factors were detected by western blotting and reverse transcription polymerase chain reaction (RT-PCR).

RESULTSThe morphological observation of BMSC showed either spindle or polygonal pattern. The cellular phenotypic marker of the third passage was CD29 positive and CD34 negative. The growth curve possessed "S" pattern. The intensity of calfilication in BMSC was higher in SATB2 transfection group (IA value 125974 ± 241) than that in the control groups (IA value 178486 ± 406). Moreover, cell migration rate increased in SATB2 transfection group [width of scratch (0.72 ± 0.01) mm] compared with control group [width of scratch (0.83 ± 0.03) mm]. In addition, the mRNA expression of osteogenic factors runt-related transcription factor 2, Osterix, activating transcription factor 4, integrin-binding sialoprotein were upregulated.

CONCLUSIONSCells cultured with this method have general biological characteristics and osteogenic differentiation potential in vitro. SATB2 can promote osteoblasts differentiation of BMSC.
