Recent studies suggest that changes of cervical vestibular-evoked myogenic potential (cVEMP) could be observed postoperatively, which reflects the degree of damage to saccule caused by cochlear implant (CI). The waveform of cVEMP can display the influences of surgical methods, ear disease condition, machine status and other factors on saccule, therefore it shows important clinical value in diagnosis and treatment. Two possible changes of cVEMP may be observed after CI. One is negative response and the other is impairment, which reflects surgical injury to saccule with varing degree. However, a uniform quantitative conclusion in cVEMP parameters is still expected. By reviewing the studies in cVEMP of CI reciepients, a typical changing pattern was discovered and a more comprehensive understanding about vestibular changes after cochlear implant was achieved.

Objective To investigate the expression of endothelin converting enzyme (ECE) mRNA in patients with acute cerebral infarction (ACI) and its clinical significance.Methods Blood samples from 40 patients with ACI (patient group) within 72 hours after the onset of ACI and 28 gender and age-matched healthy subjects (control group) were collected on admission. Plasma concentrations of endothelin-1 (ET-1) as well as the serum levels of cholesterol, triglyceride, low density lipoprotein,high density lipoprotein, apoA1, apoB, lipoprotein a and fasting plasma glucose in each sample were measured and analyzed. Additionally, semi-quantitative RT-PCR was performed to check the ECE mRNA level in the blood cells. European stroke scale (ESS) was used to evaluate ACI patients' neurological deficit on admission.Results (1) ECE mRNA could be detected in every blood sample from either patient group or control group. However, the ECE mRNA level increased significantly in the patient group compared with that in the control group (0.31?0.092 versus 0.25?0.10, t=2.46, P=0.016). (2) The plasma ET-1 concentration in patient group was also significantly higher than that of control subjects (183.27?56.63pg/ml versus 156.47?34.24 pg/ml, t=2.23, P=0.029). (3) Plasma ET-1 concentration was negatively correlated with ECE mRNA level in the control group (r=-0.452, P=0.021). However, the result in the patient group was not the same as the control group. (4) The ET-1 concentration and ECE mRNA level in the patients had histories of hypertension, diabetes mellitus and stroke were not significantly different from those in the patients without these histories. (5) No significant correlation existed between plasma ET-1 concentration and ECE mRNA level and age of the patient, ESS score, fasting plasma glucose and serum lipid. Conclusions ECE mRNA level is significantly increased in the early stage of ACI, which may be associated with the acute-phase reaction of cerebral infarction and may have deleterious effects on the development of neuronal injury. Our results suggest the protective reflection in the endothelin system of normal human body may be disturbed by the onset of ACI. The relationship between ECE mRNA level and neurological deficit degree, stroke risk factors is worthy for further study.

OBJECTIVE To explore the situation of bacteriological examination in every clinical department,know distribution and drug resistance of pathogenic bacteria,and offer the help about diagnosis and reasonable using antibiotics.METHODS Using the Microscan A/S-4 to identify the microbes and microbial sensitivity tests according to pathogens from more than twenties clinical departments between 2004 and 2005.RESULTS The clinical delivering rate was low,and samples were dispersive.The samples mostly were sputum,pus,urine and blood,and their rate was 52.15%.The first three pathogenic bacteria were totally 13 kinds of species in all kinds of departments.The main pathogenic bacteria in the internal medicine such as in the department of respiration,department of gerontology,department of endocrinology and so on were mostly Klebsiella pneumonia and Escherichia coli.The main pathogenic bacteria in department of neurosurgery,ICU,department of burn and department of trauma were mostly Pseudomonas aeruginosa,Acinetobacter baumannii/haemolyticus,Enterobacter cloacae and Staphylococcus aureus,These bacteria might lead to nosocomial infections in our hospital too.Their rate was 52% and drug-resistance was serious.A.baumannii/haemolyticus and E.cloacae were only sensitive to imipenem.P.aeruginosa was most sensitive to piperacillin/tazobactem and next to ceftazidime,amikacin and ciprofloxacin.CONCLUSIONS There are the serious phenomena that P.aeruginosa,A.baumannii/haemolyticus and E.cloacae are highly resistant to many antibiotics.We will much more attend and study it.The clinics must attend it and improve the delivering rates of cultured sample.

Objective To observe clinical effects and side reactions of Huayu pill combined with TC (Paclitaxel+Carboplatin) chemotherapeutic regimes on treating epithelial ovarian cancer. Methods All 60 patients with the epithelial ovarian cancer were randomly divided into the treated group (Huayu pill combined with TC chemotherapeutic, n=30) and the control group (TC chemotherapeutic regimes, n=30). Results The effective rate of the treated group and the control group was 46.7% and 37.9% respectively. The objective response rate (CR+PR+SD) was 86.7% in the treated group, while this rate was 68.9% in the control group (P

Objective To explore the clinical,imaging and pathologic features of hypertrophic cranial pachymeningitis (HCP).Methods The clinical data of one HCP patient who treated in our hospital and other 77 HCP patients from literatures were analyzed retrospectively.Results The clinical manifestation of all the 78 HCP patients had chronic headache,multiple cranial nerves impairment.The secondary was psychiatric disorder(10.3%),ataxia(9.0%) and seizure disorder(6.4%).Hemiplegia,menorrhea and galactosis were found few.Headache was the first onset symptom in the 74 cases (94.9%).HCP was often misdiagnosed subarachnoid hemorrhage,hypotensive cranial pressure headache and cerebral venous sinus thrombosis in early stage.MRI demonstrated local or diffused thickened dura,especially in cerebral falx and/or tentorium of cerebellum,which could be enhanced through reinforced scanning.Pathological evidence indicated an obvious proliferation of dura fiber tissue accompanied with inflammatory cells infiltration.Corticosteroid was effective to all the cases.Conclusions The clinical manifestation of HCP was multiplicity,but it mainly was chronic headache and multiple cranial nerves impairment.MRI demonstrates local or diffused thickened dura especially in cerebral falx and/or tentorium of cerebellum.MRI has an important significance for diagnosis.

Myogenic potentials evoked by air conducted sound (ACS), bone conducted vibration (BCV) or galvanic pulses can be recorded with surface electrodes over contracted muscles. These myogenic potentials are of vestibular origin (utricle and saccule) and so these potentials are called vestibular evoked myogenic potentials (VEMPs). Since the vestibular system has projections to many muscle systems, there are many such VEMPs. In this review, we discuss the generated origin, response pathway, waveform characteristics and clinical application of ocular vestibular-evoked myogenic potential (oVEMP).
