ObjectiveTo investigate the management of myonephropathic-metabolic syndrome (MNMS) after acute arterial occlusion. Methods17 cases of MNMS caused by acute arterial occlusion were restrospectively reviewed. Results5 cases were cured, 6 cases died of sudden cardiac arrest induced by hyperkalemia, and another 6 cases died of multiple organ dysfunction syndrome (MODS) complicated by acute renal failure. The total mortality rate was 71% and the amputation rate was 41%.ConclusionEarly revascularization should be performed in acute arterial occlusion. In patients with compartment syndrome, fasciotomy should be performed as soon as possible. Early amputation of gangrene limb is very important to prevent MNMS. Early and effective fluid resuscitation and alkalinization is the key point to prevent ARF, early hemodialysis for ARF is very important in treating MNMS.

Objective To explore the possible mechanism of miR 34a/Bcl-2 apoptotic pathway in the mouse model of age-related hearing loss.Methods A C57BL/6 mouse model of age-related hearing loss was conducted,and 4-week-old and 12-month-old mice were considered as the objects.The auditory brainstem response (ABR) was used to test the hearing function.The TdT-mediated dUTP nick end labeling (TUNEL) was used to observe the apoptosis of neuron in auditory cortex.The mRNA and protein levels of miR-34a,Bcl-2 and caspase 3 were detected by real-time PCR and Western bloting,respectively.Results The ABR showed that the hearing threshold level at 4,8,16,32 kHz were higher in 12-month-old mice than in 4-week-old mice [(80.0±2.5) dBHL vs.(32.0 ±4.5) dBHL,(74.0±3.5) dBHL vs.(51.0±1.2) dBHL,(86.0±4.6) dBHL vs.(51.0±3.5) dBHL,(87.0±6.6) dBHL vs.(56.0±1.5) dBHL,all P＜0.05].Compared with 4 week-old mice,the total number of neurons in auditory cortex was decreased,the number of apoptosis neurons was increased,the expressions of miR-34a (t=6.02,P=0.001),Bax (t=6.51,P=0.012) and Caspase 3 (P=0.023) rised,and the expression of Bcl-2 (t=7.12,P=0.032) declined in 12 month-old mice.Conclusions The activation of miR-34a/Bcl-2 apoptotic pathway may be one of the mechanisms of age-related hearing loss.

Objective To evaluate and characterize tinnitus patients, and provide profiles for further studying tinnitus.Methods This study included 2 171 tinnitus patients seeking treatment between Janurary 2014 and December 2015 from department of head and neck surgery,Sun Yixian Memorial Hospital,Zhongshan University.Tinnitus measurements consisted of pure tone audiometry and tinnitus matching procedures.The characteristics of tinnitus were analyzed by the essential information and auditory checks of the patients.Results Average age was 44.08±15.37 years old.Tinnitus frequently occurred between 41 to 50 years old(491 cases,22.60%).Unilateral tinnitus was more than bilateral tinnitus, while the cranial tinnitus was rare.The patients with mild or moderate tinnitus had the largest population,with higher average hearing threshold at 8 000 Hz in tinnitus ear than non tinnitus ear.The highest frequency of tinnitus matching frequency was high frequency(4~8 kHz).The first three causes for tinnitus were unknown reasons,sudden deafness and middle ear disease.Conclusion Larger population was subjective tinnitus.Tinnitus was closely related with hearing loss.The causes for tinnitus were complex.Tinnitus retraining therapy is a treatment that is worth to be popularized.

OBJECTIVE To evaluate the short-term efficacy of ear molding in the treatment of congenital auricular deformation.

Objective To explore the effects of survivin on radiation injury and its relation to caspase 9/6,3 activity. Methods ① IEC 6 cells were treated under hypoxic environment for 8 h and followed by reoxygenation for 24 and 48 h, and then the expression of survivin was identified by Western blotting. ② After treatment with 35 Gy 60 Co , the apoptosis rate in different groups was detected with FACS and the caspase 9/6,3 activity was tested using the caspase 9/6,3 assay kit. Results Hypoxic preconditioning could induce the expression of survivin in IEC 6 cells and survivin could decrease the caspase 3 activity, resulting in reduced apoptosis rate induced by radiation. Conclusion Survivin induced by hypoxic preconditioning can inhibit the apoptosis induced by radiation by reducing the caspase 3 activity.

Objective To evaluate early and dynamic changes of the left ventricular systolic function of patients with septic shock by two-dimensional speckle tracking imaging (2D-STI), and to provide guidance for treatment and prognosis.Methods Fifty-eight septic shock patients admitted to intensive care unit (ICU) of Subei People's Hospital from January 2016 to April 2017 were enrolled. The septic shock patients were given early fluid resuscitation. The left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), early diastolic mitral flow velocity/early diastolic mitral annular peak velocity (E/Em) were obtained by conventional echocardiography, and the left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS) were obtained by 2D-STI before fluid resuscitation and 1, 3, 7, 14 days after fluid resuscitation. According to the 28-day survival, the septic shock patients were divided into survival group (38 cases) and death group (20 cases). Thirty normal subjects with age and sex matched were selected as control group.Results① Compared with control group, heart rate (HR) and LVESV were increased [HR (bpm): 92.71±12.51 vs. 73.07±5.52, LVESV (mL): 42.50±7.89 vs. 38.73±4.23, bothP < 0.05], while LVEF, GLS, GCS were decreased [LVEF: 0.57±0.06 vs. 0.61±0.03, GLS: (-17.72±1.35)% vs. (-22.07±1.95)%, GCS: (-17.08±1.49)% vs. (-22.98±1.97)%] in septic shock group (allP < 0.01). ② Compared with the data before fluid resuscitation, heart rate was declined (bpm: 87.83±11.50vs. 92.71±12.51,P < 0.01), while LVEDV and LVEF were increased [LVEDV (mL): 102.32±9.23 vs. 99.24±8.86, LVEF: 0.59±0.05 vs. 0.56±0.06] in patients of the septic shock after fluid resuscitation (allP <0.01). ③ With the extension of treatment time, HR, LVEDV, LVESV, E/Em were increased gradually, and LVEF, GLS, GCS, GRS were decreased gradually in dead patients. In septic shock patients, compared with survival group, GCS was significantly different on day 1 [(-15.98±1.41)% vs. (-17.66±1.22)%,P < 0.05], HR, LVEDV, LVESV, GLS were significantly different on the 3rd day [HR (bpm): 104.60±10.94 vs. 88.71±5.06, LVEDV (mL): 109.69±10.00 vs. 103.99±5.74, LVESV (mL): 47.78±7.21 vs. 42.29±5.13, GLS: (-14.44±0.92)% vs. (-16.36±1.00)%, allP < 0.05], LVEF, GRS were significantly different on the 7th day [LVEF: 0.47±0.07 vs. 0.58±0.04, GRS: (28.27±3.23)% vs. (31.48±3.12)%, bothP < 0.05], and E/Em was significantly different on the 14th day (12.81±1.56 vs. 10.61±1.27) in dead group (P < 0.05).Conclusions Our study demonstrates myocardial dysfunction at the early phase in septic shock patients, and 2D-STI GCS can be more sensitive than the conventional echocardiography to determine prognosis. 2D-STI GCS, GLS, GRS were not volume-load dependent parameter. Low levels of GLS, GCS might suggest a poor prognosis.

[ABSTRACT]OBJECTIVETo evaluate the short-term efficacy of Eustachian tube balloon dilation (ETBD) in the treatment of symptomatic Eustachian tube dysfunction (SETD) by subjective and objective analysis.METHODS Forty patients who underwent ETBD were included. Subjects’ inclusion criteria were as followed: symptoms of ETD (aural fullness predominantly, with or without otalgia, muffle hearing and tinnitus), normal tympanic membrane, type A or C tympanograms, and without a history of any middle ear diseases. Main outcomes including subjective improvement, otoscopy, pure-tone audiometry, impedance audiometry, R-value in tubomanometry (TMM) and Eustachian Tube Score (ETS) were assessed 1 week and 6 months postoperatively.RESULTSAll cases were dilated successfully. A significant effect of treatment was documented when measuring subjective improvement, impedance audiometry, R-value in TMM and ETS 1 week and 6 month postoperatively. Subjective symptoms were not relieved only in one patient. The overall success rate for all patients was 98%.CONCLUSIONETBD can provide short-term benefits to those who are diagnosed with SETD and refractory to medical management. SETD might be an optimal indication for ETBD in the treatment of ETD.

Objective To summarize the condition of surgical treatment and prognosis of 54 cases of jugular foramen tumors in the past 5 years.Methods All 54 cases were treated with operation by Fisch approach.Thirty-eight cases underwent total or near total resection of the tumor.Most resection of the tumor was underwent in 16 cases,in which,7 cases underwent postoperative radiotherapy or gamma knife therapy.The facial nerve monitoring was used in all cases.The facial nerve was anatomized and shifted in 35 cases,was just anatomized like a bridge in 10 cases,and was excised partly in 9 cases,in which,4 cases underwent facial-hypoglossal nerve anastomosis and 3 cases underwent transplantation of facial nerve and great auricular nerve.Results The external auditory canal was closed in 41 cases.The near pedicled temporalis muscle flap was obliterated in the operating cavity in 35 cases.Six cases underwent fat filling in the operating cavity.Eighteen patients showed facial palsy in varying degrees after operation.Among them,14 cases improved to different extents in 2 weeks to 9 months and 4 cases did not improve.One case showed recurrent laryngeal nerve paralysis in the same side before operation and improved in half a year after operation.Postoperative subcutaneous hematoma occurred in 2 cases,wound infection in 1 case.All the cases improved by debridement suture and anti-infective therapy.The cavity filling necrosis occurred in 2 cases,which recovered after debridement and dressing.For half a year after operation,except 9 cases of residual or recurrent,and the rest showed no recurrence.Conclusion The Fisch approach of surgical treatment of jugular foramen tumors can provid good exposure,clear vision,facilitate hemostasis.The skills of intraoperative facial nerve monitoring,facial nerve anatomy like a bridge or anatomy and shift when necessary are beneficial to the total or nearly total resection of tumor and reduce the injury of facial nerve.The operating cavity filling and selective external auditory canal closure can effectively reduce the surgical cavity effusion and the incidence of postoperative infection.
