A male patient, 55 years old, suffered from intermittent sound,voice depression and shortness of breath for one year,and from dysphagia for 3-4 months. Through fiber laryngoscopy,we could see tumor in the left posterior aryepiglottic fold. The tumor's surface was smooth. A portion of the tumor protruded to the laryngeal cavity and the aryepiglottic fold external,it also covered most of the glottis. Bilateral vocal cord were smooth and had good mobility. Throat CT demonstrated an irregular soft tissue mass on the left side of the aryepiglottic fold in supraglottic area with obscure normal boundary from adjacent structure. The left side of pyriform sinus became shallow without obvious bone destruction. The pathological report showed pleomorphic adenoma. The diagnosis was laryngeal pleomorphic adenoma.

Hemorrhagictransformation(HT)referstointracerebralhemorrhageoccurredwhenthe blood vessels restore blood flow after acute ischemic stroke. It is one of the common complications of ischemic stroke. HT may not have any clinical manifestations and can also be manifested as limb paralysis aggravation, decreased consciousness level, and other symptoms. The symptomatic HT may result in prolonged hospitalization, increased disability and fatality. Therefore, research on the mechanisms and risk factors for HT may be expected to provide the basis for clinical treatment, and thus improve the prognosis of patients. This article review s the formation mechanism of HT, risk factors, screening of high-risk patients, and prevention and treatment.

OBJECTIVE: To study the clinical characteristics of early tinnitus in patients with sudden deafness. METHOD: Forty-seven patients with sudden deafness and early tinnitus recieved subjective review and filled out classified questionnaire of tinnitus. By pure tone audiometry and tinnitus matching test, we obtain the distribution, quantity and matching loudness of tinnitus patients. RESULT: (1) Objective examination: the most common frequencies of tinnitus were 8000 Hz and 4000 Hz. The most common numbers were two frequencies. The matching loudness was (16.63 ± 8.37) dB. (2) Subjective examination: the tinnitus was monotone (74.0%), sustained (89.0%), third level loudness (45.0%), third level annoying (60.0%), high frequency (83.0%), sound of cicadas (66.7%). The most influencing factors were hearing (28.2%) and mood (29.5%). (3) Relationship between tinnitus and pure tone hearing threshold curve: there was a significant correlation between the frequency of pure tone audiometry and the matching loudness of tinnitus (r = -0. 370, P < 0.01). There was no significant correlation between the frequency of pure tone tinnitus and the matching loudness of tinnitus (r = -0.083, P > 0.05). CONCLUSION (1) The results of subjective examination were consistent with those of objective examination. (2) The tinnitus should be considered in the early treatment of sudden deafness.

OBJECTIVE To study the effect of frequency difference and intensity difference on mismatch negativity (MMN) change in normal persons. Emphatically to observe the effect on the latency and amplitude of normal people's MMN, as well as the threshold of the acoustic difference which may induce the MMN. METHODS Twenty-four adults were included in this study. Their thresholds of pure tone audiometry were within 20dBHL. The MMN were measured by using the Smart EP ( ear potentiometer provided by the company of Intelligent Hearing) and the rule of the change by the difference of frequency and intensity to the latency and amplitude of normal people’s MMN were studied. RESULTS Along with the decreasing of the difference of the frequency, the MMN latency prolonged gradually. The amplitude of the MMN decreased gradually as the decreasing of the intensity difference. CONCLUSION A stable MMN graph is an important indicator of objective physiological test with hearing distinguish.

Objective To investigate the relationship between microalbuminuria (MAU) and the risk factor for acute ischemic stroke,the severity of the disease and outcomes.Methods A total of 156 consecutive patients with acute ischemic stroke were enrolled prospectively.They were randomly divided into either an MAU positive group (≥ 30 mg/g) or an MAU negative group (＜ 30 mg/g) according to urinary albumin/creatinine ratio (UACR).They were also randomly divided into either a good outcome group (0-2) or a poor outcome group (＞2) according to the modified Rankin scale (mRS) scores.The various demographic and clinical data were compared,and the poor outcome of acute ischemic stroke and the independent factors of positive MAU were analyzes.Results A total of 156 patients with acute ischemic stroke were enrolled,including 84 males and 72 female; aged 53 to 78 years (mean 65.4 ± 6.2); the time from onset to admission was 1.5 to 28 h; 94 patients had good outcomes,62 had poor outcomes,and no one died; MAU was positive in 76 patients and MAU was negative in 80 ones.Multivariate logistic regression analysis showed that advanced age (odds ratio [OR] 1.992,95％ confidence interval [CI] 1.108-2.374; P =0.015),complicated with diabetes (OR 2.497,95％ CI 1.177-5.298; P =0.017) and atrial fibrilhtion (OR 2.338,95％ CI 1.062-5.148; P =0.035),high serum homocysteine (Hcy) level (OR 2.541,95％ CI 1.073-6.02; P =0.047) and UACR (OR 2.130,95％ CI 1.396-3.017; P =0.001),MAU positive (OR 3.291,95％ CI 1.681-6.444; P =0.001),high baseline National Institutes of Health Stroke Scale (NIHSS) score (OR 9.196,95％ CI 2.828-19.815; P＜ 0.001) were the independent risk factors for poor outcomes in patients with acute ischemic stroke.There were significant differences in the proportion of the patients complicated with diabetes (P =0.038) and fasting blood glucose level (P =0.025),serum Hey level (P =0.022),and carotid intima-media thickness (IMT) (P =0.019) between the MAU positive group and the MAU negative group.The proportion of anterior circulation infarction was lower (P =0.033),the rates of the baseline NIHSS score (P =0.003) and poor outcome were higher in the MAU positive group (P ＜ 0.001).Multivariate logistic regression analysis showed that increased diabetes (OR 2.237,95％ CI 1.036-4.829; P =0.040) and fasting blood glucose (OR 1.223,95％ CI 1.145-1.673; P =0.027),the increased Hey level (OR 2.542,95％ CI 1.047-6.612; P=0.025),carotid artery IMT (OR 1.295,95％ CI 1.106-1.362; P =0.023) and baseline NIHSS score (OR1.206,95％ CI 1.044-1.219; P =0.023) were correlated independently with the positive MAU in patients with acute ischemic stroke.Conclusions Positive MAU is one of the independent risk factors for poor outcomes of acute ischemic stroke,it is closely associated with some risk factors for acute ischemic stroke,and it has a significant impact on the severity of acute ischemic stroke and outcomes.

BACKGROUND: Matrix metalloproteinase (MMP) degrades extracellular matrix, which is a necessity of joint destruction in rheumatoid arthritis patients. MMP-2 and MMP-9 can evaluate rheumatoid arthritis and serve as an index to predict progressive destruction of the joint. OBJECTIVE: To observe heterogenous allogeneic umbilical cord blood stem cell (UBSC) transplantation on MMP-2 and MMP-9 expression in the spleen of mice with type Ⅱ collagen-induced arthritis. METHODS: Fetus cord blood was sterilely obtained and cord blood stem cells were separated. The C57BL/6(H-2b) mice were assigned to five groups (n=10). Except normal control group, models of collagen-induced arthritis were established using complete Freund's adjuvant + type Ⅱ collagen. Mice from the methopterin group were intragastrically administered methopterin suspension 0.017 5 g/kg, once every 5 days. Other groups used caudal vein injection. Mice from the model and normal control groups were injected with saline. Mice from the mono-UBSCs group and double-UBSCs group were injected with 2×106/kg UBSCs from one and two parents. At 42 days following injection, animals were sacrificed and the ankle joint was obtained for histopathological detection. MMP-2 and MMP-9 mRNA expression in the spleen was examined using reverse transcription-polymerase chain reaction. RESULTS AND CONCLUSION: Double-UBSC transplantation could significantly inhibit inflammatory cell infiltration in synovial tissue of mice with type Ⅱ collagen-induced arthritis, repaired impaired cartilage tissue. The repair effect was better than that in methopterin group and mono-UBSCs group. MMP-2 and MMP-9 mRNA expression in the spleen was significantly lower in the double-UBSCs group than the mono-UBSCs group (P < 0.01). These suggest that heterogenous allogeneic double-UBSCs transplantation participated in pathological changes in rheumatoid arthritis cartilage and in synthesis of cartilage extracellular matrix and effectively treated rheumatoid arthritis by regulating MMP-2 and MMP-9 mRNA expression.

Objective To discuss the clinical efficacy of balloon occlusion technique in treating pernicious placenta previa.Methods Between January 2015 and March 2016,a total of 16 matcrnal patients with pernicious placenta previa,who were admitted to the Interventional Department of Qujing Municipal First People's Hospital,received balloon occlusion management to assist obstetrician in dealing with placenta previa.Central type of placenta previa with highly suspected placenta implantation were diagnosed in 15 patients by color ultrasound or MRI.Balloon catheters were placed in bilateral internal iliac arteries before cesarean section was carried out,and immediately after the fetus was taken out the balloons were inflated to temporary occlude the targeted arteries.Based on the hemostatic status the balloon catheters were timely retrieved.One patient received emergency temporary balloon occlusion of abdominal aorta,and laparotomy revealed that the placenta had penetrated to the subserosa of uterine anterior wall,and total hysterectomy had to be carried out.Results Successful balloon occlusion was achieved in all 16 patients.The mean blocking time of the artery was 15 minutes and the amount of blood loss was 300-1200 ml.Conclusion In treating pernicious placenta previa,balloon occlusion treatment before cesarean section is safe and reliable,it can significantly reduce the amount of blood loss during surgery,make quick and effective hemostasis,provide a clear surgical field for the performance of cesarean section,and,more important,save the maternal life.This effective technique has fully showed the necessity of multidisciplinary collaboration,including obstetrics,interventional radiology,etc.

Objective To explore the change of microRNA let-7b in heat acclimatization/heat stroke rat models and its relation with HSP70,IL-6,TNF-α,TGF-3 and IL-12,and analyze its clinical significance.Methods 60 male rats with almost the same anal temperature,weight,and weeks' age were selected from Laboratory Animal Center in the Second Military Medical University.They were randomly divided into control,heat acclimatization,heat stroke groups averagely.Heat acclimatization/heat stroke rat models were built in hot climate simulated animal tank,blood was collected from cordis apex and serum was separated.Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to test microRNA let-7b in serum,enzyme-linked immunosorbent reaction (ELISA) was to measure the protein level of HSP70,IL-6,TNF-α,TGF-β and IL-12 in serum.Kruskal-Wallis H test was used to analyze quantitative data in the three groups,Spearman rank correlation coefficient was used to reveal relation between two variables in heat stroke group.Results M values of miRNA let-7b in control,heat acclimatization,heat stroke groups were 0.99,1.04 and 1.93 separately,Q values were 0.30,0.25 and 0.44 (x2 =38.95,P＜0.001),separately,with statistical significance.The results of pairwise comparison showed no statistical difference in control and heat acclimatization (P＞0.05),but there were differences in control and heat stroke,heat acclimatization and heat stroke groups statistically (P＜0.05).Spearman correlation analysis showed that in heat stroke group,let-7b was positively related with HSP70,TNF-α and IL-6 (rs =0.579,0.498 and 0.609,P＜0.05) with statistical significance.Conclusion miR let-7b might involve in the pathology of heat stroke,it provided a potential biomarker for monitoring patients in high temperature and humidity clinically.
