Objective To investigate the clinical effect of intratympanic injection of dexamethasone in treatment of sudden deafness in different time windows.Methods 60 patients (60 ears) with sudden deafness were selected.Sixty patients were divided into control group and observation group according to the random number table method,30 cases (30 ears) in the control group and 30 cases (30 ears) in the observation group.The two groups were given systemic basic therapy, intravenous vinpocetine, alprostadil improve microcirculation, while hyperbaric oxygen therapy,12 days for a course of treatment, treatment for 2 courses.In the control group, dexamethasone was intravenously administered for 12 days.From the 7th day, dexamethasone was injected into the tympanic cavity and injected once every other day.The observation group was treated with dexamethasone at the same time.Injection of dexamethasone, treatment method and time were the same as the control group.At the end of the treatment, the clinical curative effect of the two groups was compared.The average hearing thresholds of the two groups were observed before and after treatment.The dizziness, tinnitus and hearing recovery time of the two groups were observed.Results The total effective rate was 96.67% in the observation group and 93.33% in the control group, the difference was not statistically significant (x2 =0.97,P> 0.05).After treatment, the average hearing threshold of the two groups was significantly improved (t=7.69,8.23,all P<0.05),the average hearing threshold of the observation group was higher than that of the control group, the average hearing threshold before and after treatment had statistically significant differences (t=2.34,2.67,all P<0.05).In the observation group, dizziness, tinnitus and hearing recovery time were shorter than those in the control group (t=3.32,3.14,3.67,all P<0.05).Conclusion The effect of dexamethasone combined with systemic treatment of sudden deafness in patients compared with intratympanic injection of dexamethasone after intravenous administration of dexamethasone is not significantly different, but the improvement of hearing threshold after treatment compared with the latter is obvious, and the average time to disappear symptoms is shorter than the latter, and therefore worthy of clinical promotion.

Reperfusion therapies(thrombolysis,mechanical thrombectomy,or stenting,etc.) for acute ischemic stroke are the most effective therapy.Reperfusion therapy may limit ischemic tissue enlargement,leading to a reduced infarct size and favorable clinical outcome by restoring the blood flow before the salvageable penumbra became the progress of ischemic brain infarction.intravenous (IV) recombinant tissue plasminogen activator (rt-PA) therapy is the only proven effective treatment of acute ischemic stroke.Although thrombolytic therapy has matured,but the standard intravenous thrombolytic therapy (non-enhanced computed tomography (CT)-guided,3 h time window,the intravenous injection of tPA) have many restrictions,including a short therapeutic time window,recanalization rate was only 50 %,and the major dangers of symptomatic hemorrhagic transformation.As a result,currently in clinical practice,only a minority of patients (usually 1% to 3%) received thrombolytic therapy.So there are some issues still need to be further explored,such as the expansion of thrombolytic time window,a new thrombolytic drugs are used for more than 3h incidence of acute ischemic stroke patients,the evaluation of new reperfusion methods (in particular,multi-modal imaging technology),intravenous,and intra-arterial thrombolysis combined application of thrombolytic therapy,and new anti-platelet drug combination,and the application of mechanical devices or by transcranial Doppler ultrasound to promote the role of thrombolytic drugs.

Objective:To study the activation and significance of NF- ?Bp65 in active Heymann nephritis in rats. Methods : Female Wistar rats 6~8 weeks of age were used. The nephritis was induced with FxIA/CFA by subcutaneous injection and the control group with CFA . After the rats were killed, the activation of NF- ?Bp65 in renal tissue was observed by use of immunohistochemical dyeing ;also observed were the changes in pathology ,urinary protein and albumin and the relationship between these 3 factors. Results: Compared with the control group, the thickness of GBM increased (F

20m, hypertrophy of nuclei, dilatation of T tubules, mutiple intercalated discs and increase of mitochondria and myofibrils. But the atrial cardiac muscle cells with degeneration showed myofibrillar lysis, abnormal Z bands, mitochondrial swelling and extramembranous disruption, sarcoplasmic reticulum proliferation and dilatation,myelin figures formation and interstitial fibrosis These results suggested that the degree of hypertropy and degeneration of atrial cardiac muscle cells was related to the types, injuried size of congenital heart disease and the age, cardiac functional state of patients

Objective To analyze the topology of IFN-induced transmembrane(IFITM) protein in porcine peripheral blood lymphocytes(PBMCs) and detect the change of IFITM mRNA transcription in PBMCs after porcine reproductive and respiratory syndrome virus(PRRSV) infection in vitro.Methods PRRSV,porcine circovirus 2(PCV2) and Japanese encephalitis virus(JEV) negative anticoagulant blood of piglets were collected aseptically and isolated for PBMCs.Porcine IFITM CDS sequence was amplified by PCR,sequenced and analyzed for topology.PBMCs were infected with PRRSV in vitro.Cell samples were collected at 12,24,36 and 48 h after infection,detected for PRRSV infection by RT-PCR,and detected for mRNA transcription level changes of IFITM1,IFITM2 and IFITM3 by RT-PCR.Results The porcine PBMCs were successfully isolated and the full-length sequence of IFITM CDS derived from PBMCs was cloned.The porcine IFITM protein might have two topological structures.PBMCs inoculated with PRRSV for 24 h produced obvious cytopathic effect.PRRSV was replicated in PBMCs.The transcription levels of IFITM1,IFITM2 and IFITM3 mRNA in PBMCs were significantly up-regulated at the early stage of PRRSV infection,and reached the peak at 12h after infection,and then gradually decreased;The transcription level of IFITM1 mRNA increased at 36 h after virus infection and then declined rapidly.Conclusion PRRSV infection in vitro significantly up-regulated the transcription level of IFITM mRNA in PBMCs,indicating that IFITM was involved in the antiviral immune response of PBMCs.This study provided a reference for revealing the natural immune response against PRRSV in vivo.

Objective To study systematically regional anatomy of lumbar sympathetic trunk to provide anatomic information for endoscopic lumbar sympathectomy (VALLS). Method The anatomy of the lumbar sympathetic trunk and its relationship with neighboring structures were studied in 128 sides of adult cadavers, and it was substantiate in 13 cases of endoscopic lumbar sympathectomy. Results (1) The location, shape and number of the sympathetic ganglia were quite variable. The number varied from 1 to 6 on one side. (2) It was found that the lumbar sympathetic trunk split into 2-3 branches at the distal portion. (3) Lumbar arteries were all located under the lumbar sympathetic trunk and the lumbar veins situated superior to the trunk in 68.42%±4.35% of instance. (4) Genitofemoral nerve was found to pierce the psoas muscle at the level of 2nd to 4th vertebra or its intervertebral discs. It was only 0.81±0.48 cm away from the medial rim of the psoas muscle. (5) Distance between ureter- iliac vessel junction and the lateral edge of the psoas muscle was 3.36±0.59 cm on the left side, and 3.41±0.59 cm on the right side. (6) A report of the experience of our 13 VALLS was presented. Conclusions Because of great variation and complicated anatomic relation between lumbar sympathetic trunk with its neighboring structures, familiarity to the anatomy of the retroperitoneal space is cracial for a successful minimal invasive laparoscopic lumbar sympathectomy.

Cytokeratin 1 4 (CK1 4)has a different degree of expression in NSCLC,breast cancer,cer-vical cancer,esophageal cancer and other tumors,except in the normal basal cells.CK1 4 is mainly expressed in the peripheral part of the tumor,which is rarely expressed in the non-aggressive part.Usually the higher malignant of the tumor has the more expression of CK1 4.Given all that,CK1 4 gene plays an important role in the tumor progression and metastasis in a variety of tumors,which can be considered as an biomarker being used in the diagnosis,treatment and prognosis evaluation.
