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 study effects of exectin hydrochloride and intensity modulated radiotherapy in treatment of patients with advanced lung cancer and its effect on levels of carcinoembryonic antigen (CEA), neuron-specific enolase (NSE) and serum glycoprotein antigen 199 (CA199). Methods 88 patients with advanced lung cancer were selected from June 2014 to June 2016 in our hospital were selected and randomly divided into observation group and control group, 44 cases in each group.In the control group, the patients were treated with IMRT, and the observation group was treated with exectin hydrochloride on the basis of control group.The clinical efficacy and adverse reaction were compared between the two groups.The levels of CEA, NSE and CA199 before and after treatment were analyzed.Results After treatment, the total effective rate in the observation group 84.09% was significantly higher than the control group 52.27%, the difference was statistically significant (P<0.05).Before treatment, the levels of CEA, NSE and CA199 of the two groups had no significantly different, after treatment, the levels of CEA, NSE and CA199 of the two groups were significantly lower than before treatment, the difference was statistically significant (P<0.05).CEA, NSE, CA199 levels in the observation group were significantly lower than the control group, the difference was statistically significant (P<0.05).There was no significant difference in adverse reaction rate of I-II, III-IV liver function, gastrointestinal reaction, bone marrow suppression and acute radiation pneumonitis in observation group and control group.Conclusion Ectectin hydrochloride combined with intensity modulated radiotherapy can effectively reduce the levels of CEA, NSE and CA199 in patients with advanced lung cancer, and the clinical efficacy is good, and will not increase the adverse reaction rate.

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 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.

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).
