Based on the theory of Zangfu organs and meridians, it draws on the essence of the academics of doctors in the past dynasties, especially the important theory of Huangdi Neijing to guide the clinical practice of acupuncture and moxibustion. This paper introduces the academic thought of HE's tube acupuncture. Mr HE believes that the pathogenesis of vertigo is mainly the first, kidney essence is deficient, and the heart fire burns alone,therefore disharmony occurs between heart and kidney. Secondly, liver and kidney Yin's deficiency, Yin is deficient while Yang is hyperactive or Yin is deficient and wind. Thirdly, the spleen Qi is deficient, Qingyang fails to ascend, and the main Zangfu organs are responsible for the liver, spleen and kidney. In the treatment, it emphasizes the characteristics of TCM paying attention to the whole, syndrome differentiation and treatment, selects the principal acupuncture points of the bladder meridian of foot Taiyang, kidney meridian of foot Shaoyin, hand Jueyin pericardium meridian, heart meridian of hand Shaoyin, include Kunlun(BL60), Yongquan(KI1), Neiguan(PC6), Fuliu(KI7), Daling(PC7),Shenmen(HT7), Shenmai(BL62), Tianzhu(BL10), Baihui(GV20), Beiyu points, etc. Finally, combined with the actual medical records,the clinical effect of HE's tube acupuncture technique in the treatment of vertigo is explained in detail.展开更多

Methods One hundred cases of vertigo caused by cerebellar infarction at the recovery stage were randomized into a scalp acupuncture group and a conventional acupuncture group. In the scalp acupuncture group, on the basis of the routine drug therapy, the electric stimulation was applied to the balance area and vertigo-auditory area of scalp acupuncture. In the conventional acupuncture group, on the basis of the routine drug therapy, the conventional acupuncture was supplemented. The treatment was given once a day, 6 treatments made one session. The clinical efficacy was assessed after 4 sessions of treatment. The transcranial Doppler ultrasonography （TCD） was adopted in the scalp acupuncture group to observe the changes of the mean blood flow velocity （Vm） of the anterior cerebral artery （ACA）, middle cerebral artery （MCA） and posterior cerebral artery （PCA） before and after treatment. Results After treatment, the total effective rate was 90.0% （45/50） in the scalp acupuncture group and was 68.0% （34/50） in the conventional acupuncture group, presenting the statistically significant difference in comparison （P0.05）. After treatment, Vm of ACA and MCA was increased apparently as compared with that before treatment in the scalp acupuncture group. Conclusion The electric stimulation at the balance area and vertigo-auditory area of scalp acupuncture achieves the apparent efficacy on vertigo caused by cerebellar infarction at the recovery stage and improves obviously brain blood circulation. It is significant to promote this therapy in clinical practice.展开更多

Objectives: To calculate the incidence pBPPVsr, compare the characteristics of the patients with pBPPVsr and BPPV not spontaneously resolved and describe the spontaneous resolution in the natural course of BPPV. Methods: Multicenter prospective descriptive study. During a one-year period, all patients with suspected BPPV that presented to the Neurotology Units of five participating centers were recruited. The incidence of pBPPVsr was calculated as a percentage of the total number of patients with BPPV. The prevalence of several variables was compared between pBPPVsr and BPPV not spontaneously resolved. The timing of spontaneous resolution was estimated using Kaplan-Meier curves. Results: 457 patients met the inclusion criteria. The incidence of pBPPVsr was 33.5%. It was significantly higher in males, in patients with normal bone mass and in patients who were not taking sulpiride. A rate of 18% of spontaneous resolution after the first month and 51% after the first year was found. This percentage did not change in a significant way after this moment. The curves for males, patients under 50 and patients with normal blood pressure decreased significantly faster. Conclusions: In our serie, BPPV spontaneously resolved in half of the patients with BPPV during the first year. This seemed to occur more commonly in males and could have been hindered by sulpiride intake, osteoporosis, advanced age and high blood pressure.展开更多

Methods One hundred and eighty patients with cervical vertigo were divided into group A [acupuncture at R6nyfng （人迎ST 9） and Fengchi （风池 GB 20）, and frontal line], group B [acupuncture at Jing jiaji （颈夹脊）, GB 20 and Baihui （百会 GV 20）] and group C [intravenous infusion with ligustrazine and oral administration with flunarizine] according to simple randomization, with 60 cases in each group. For the patients in group A and group B, the treatment was conducted once a day, and ten times were considered as one course of treatment. Two days were free of treatment between two courses, and two courses were needed. For the patients in group C, the treatment was conducted for fifteen days. The contents of NPY, ET and CGRP in plasma before and after treatment were detected in patients with cervical vertigo. Results The contents of NPY in plasma of patients in the three groups after treatment were markedly lower than that before treatment （all P〈0.01）, and the differences were not statistically significant when compared the descending degrees among three groups （P〉0.05）. The contents of ET in plasma of patients in the three groups after treatment were markedly lower than that before treatment （P〈0.05, P〈0.01）, the descending degree in group A was greater than that in group B and group C, and the difference was statistically significant （P〈0.O1, P〈O.05）; while the difference was not statistically significant when compared the descending degrees between group B and group C （P〉0.05）. The contents of CGRP in plasma of patients in the three groups after treatment were markedly higher than that before treatment （P〈0.05, P〈O.O1）, the increasing degree in group A was greater than that in group B and group C, and the difference was statistically significant （both P〈0.05）; while the difference was not statistically significant when compared the increasing degrees between group B and group C （P〉0.05）. Conclusion Three vertigo-stopping needles, acupuncture and medication can regulate the contents of NPY, ET and CGRP in plasma of patients with cervical vertigo, while three vertigo-stopping needles is significantly superior to acupuncture and medication in reducing ET and increasing CGRP.展开更多

It is due to otolith rests that are free into the canals or attached to the cupulas. Well over 90% of patients can be successfully treated with manoeuvres that move the particles back to the utriculus. Among the great variety of procedures that have been described, the manoeuvres that are supported by evidenced-based studies or extensive series are commented in this review. Some topics regarding BPPV treatment, such as controlling the accuracy of the procedures or the utility of post-manoeuvre restrictions are also discussed.展开更多

Methods:Clinical data of 67 patients with H-BPPV who underwent quick repositioning maneuver in our hospital from July 2009 to November 2014 were retrospectively analyzed. The maneuver involved rotating the patient in the axial plane for 180? from the involved side towards contralateral side as quickly as possible. Results:Complete symptom resolution was achieved in 61 patients (91.0%) at one week and in 64 patients (95.5%) at 3 months post-treatment. During the repositioning maneuver process, there were no obvious untoward responses except transient nausea with or without vomiting in a few patients. Conclusion:The results indicate that the quick repositioning maneuver is an easy and effective alternative treatment in the management of H-BPPV. Copyright ? 2015 The Authors.

The common presenting symptoms of this tumor are pulsatile tinnitus and conductive hearing loss. Vertigo as the cardinal or initial symptom is extremely rare, especially in the early stages of the disease.Case presentation: A 53-year-old female patient presented only with intermittent recurrent vertigo and was later found to have a tympanomastoid paraganglioma. Her symptoms disappeared completely after resection of the tumor. This is the first report in literature of a case of tympanomastoid paraganglioma with vertigo as the single symptom.Conclusion: The tympanomastoid paraganglioma is rare and its clinical symptoms are nonspecific, so it is easy to be misdiagnosed or missed. It is worth noting that although clinically uncommon, vertigo can also be the first or sole symptom of tympanomastoid paraganglioma. Detailed physical examination and imaging examination of the ear are necessary and should be carried out meticulously.展开更多

Methods：The concentration of ET and CGRP in 64 patients with CV and 30 controls was determined by radioimmunity method. The average blood flow velocity （Vm） of bilateral vertebral arteries was detected by Transcranial Doppler（TCD）. Results：Plasma concen- tration ofET（91.48 ± 9.08 pg/ml） and ET/CGRP ratio value（2.88 ± 0.52） in vertebrobasilar arteriospasm group were both higher than those in vertebrobasilar non-arteriospasm group and in controls, while CGRP concentration（30.66 ± 6.05 pg/ml） in vertebrobasilar arteriospasm group was lower than that in vertebrobasilar non-arteriospasm group and controls respectively. The Vm of bilateral verte- bral arteries in vertebrobasilar arteriospasm group（67.97 ± 11.64 cm/s ） was higher than that in vertebrobasilar non-arteriospasm group and controls respectively, having a positive correlation with ET concentration and ET/CGRP ratio value（r1=0.52, P 〈 0.05; r2=0.59, P 〈 0.05）, but a negative correlation with CGRP concentration（r3=-0.54, P 〈 0.05）. There was no significant difference in ET and CGRP concentration, ET/CGRP ratio value and the Vm of bilateral vertebral arteries between vertebrobasilar non-arteriospasm group and the control group. Conclusion： All the results indicate that ET and CGRP are possibly the most important substance factors at the onset of CV with vertebrobasilar arteriospasm, and their imbalance of regulating vertebrobasilar arterial contraction and relaxation may play an important role in the onset of CV with vertebrobasilar arteriospasm.展开更多

The purpose of this investigation was to determine the prevalence of absent caloric-induced vertigo perception in an unselected group of patients and to assess possible predicting variables.Methods: Prospective investigation of 92 unselected patients who underwent caloric testing. Inclusion criteria were that each patient generate a maximum slow phase velocity(maxSPV) > 15 deg/sec and a caloric asymmetry of≤10%. Following the caloric, patients were asked, "Did you have any sensation of motion?"Results: Results showed 75% of patients reported motion with a mean age of 56.51 years compared to a mean age of 66.55 in the 25% of patients reporting an absence of motion. A logistic regression was performed and the overall model was statistically significant accounting for 29% of the variance in caloric perception. The significant predictor variables were patient age and maxSPV of the caloric response. The effect size for both variables was small with an odds ratio of.9 for maxSPV and 1.06 for age.Conclusions: The current investigation showed that both age and maxSPV of the caloric response were significant predictors of vertigo perception during the caloric exam. However, the association between age and caloric perception is not conclusive. Although there is evidence to suggest that these findings represent age-related changes in the central processing of vestibular system stimulation, there are additional unmeasured factors that influence the perception of caloric-induced vertigo.展开更多

文摘Objective To explore the efficacy of electric stimulation at the balance area and vertigo-auditory area of scalp acupuncture for vertigo caused by cerebellar infarction. Methods One hundred cases of vertigo caused by cerebellar infarction at the recovery stage were randomized into a scalp acupuncture group and a conventional acupuncture group. In the scalp acupuncture group, on the basis of the routine drug therapy, the electric stimulation was applied to the balance area and vertigo-auditory area of scalp acupuncture. In the conventional acupuncture group, on the basis of the routine drug therapy, the conventional acupuncture was supplemented. The treatment was given once a day, 6 treatments made one session. The clinical efficacy was assessed after 4 sessions of treatment. The transcranial Doppler ultrasonography （TCD） was adopted in the scalp acupuncture group to observe the changes of the mean blood flow velocity （Vm） of the anterior cerebral artery （ACA）, middle cerebral artery （MCA） and posterior cerebral artery （PCA） before and after treatment. Results After treatment, the total effective rate was 90.0% （45/50） in the scalp acupuncture group and was 68.0% （34/50） in the conventional acupuncture group, presenting the statistically significant difference in comparison （P0.05）. After treatment, Vm of ACA and MCA was increased apparently as compared with that before treatment in the scalp acupuncture group. Conclusion The electric stimulation at the balance area and vertigo-auditory area of scalp acupuncture achieves the apparent efficacy on vertigo caused by cerebellar infarction at the recovery stage and improves obviously brain blood circulation. It is significant to promote this therapy in clinical practice.
文摘Background:Vestibular symptoms on sitting-up are frequent on patients seen by vestibular specialists.Recently,a benign paroxysmal positional vertigo(BPPV)variant which elicits vestibular symptoms with oculomotor evidence of posterior semicircular canal(P-SCC)cupula stimulation on sitting-up was described and named sitting-up vertigo BPPV.A periampullar restricted P-SCC canalolithiasis was proposed as a causal mechanism.Objective:To describe new mechanisms of action for the sitting-up vertigo BPPV variant.Methods:Eighteen patients with sitting-up vertigo BPPV were examined with a pre-established set of positional maneuvers and follow-up until they resolved their symptoms and clinical findings.Results:All patients showed up-beating torsional nystagmus(UBTN)and vestibular symptoms on coming up from either Dix-Hallpike(DHM)or straight head-hanging maneuver.Sixteen out of 18 patients presented a sustained UBTN with an ipsitorsional component to the tested side on half-Hallpike maneuver(HH).A slower persistent contratorsional down-beating nystagmus was found in eleven out18 patients tested on nose down position(ND).Conclusions:Persistent direction changing positional nystagmus on HH and ND positions indicative of PSCC heavy cupula was found in 11 patients.A sustained UBTN on HH with the absence of findings on ND,which is suggestive of the presence of P-SCC short arm canalolithiasis,was found on 5 patients.All patients were treated with canalith repositioning maneuvers without success,but they resolved their findings by means of Brandt-Daroff exercises.We propose P-SCC heavy cupula and P-SCC short arm canalolithiasis as two new putative mechanisms for the sitting-up vertigo BPPV variant.
文摘Background: Probable benign paroxysmal positional vertigo, spontaneously resolved (pBPPVsr), is a variant of benign paroxysmal positional vertigo (BPPV) in which there is no observable nystagmus and no vertigo with any positional maneuver. Objectives: To calculate the incidence pBPPVsr, compare the characteristics of the patients with pBPPVsr and BPPV not spontaneously resolved and describe the spontaneous resolution in the natural course of BPPV. Methods: Multicenter prospective descriptive study. During a one-year period, all patients with suspected BPPV that presented to the Neurotology Units of five participating centers were recruited. The incidence of pBPPVsr was calculated as a percentage of the total number of patients with BPPV. The prevalence of several variables was compared between pBPPVsr and BPPV not spontaneously resolved. The timing of spontaneous resolution was estimated using Kaplan-Meier curves. Results: 457 patients met the inclusion criteria. The incidence of pBPPVsr was 33.5%. It was significantly higher in males, in patients with normal bone mass and in patients who were not taking sulpiride. A rate of 18% of spontaneous resolution after the first month and 51% after the first year was found. This percentage did not change in a significant way after this moment. The curves for males, patients under 50 and patients with normal blood pressure decreased significantly faster. Conclusions: In our serie, BPPV spontaneously resolved in half of the patients with BPPV during the first year. This seemed to occur more commonly in males and could have been hindered by sulpiride intake, osteoporosis, advanced age and high blood pressure.

文摘Objective To observe the effect of three vertigo-stopping needles on the contents of neuropeptide Y （NPY）, endothelin （ET） and calcitonin gene-related peptide （CGRP） in plasma of patients with cervical vertigo, and to explore its mechanism of treatment. Methods One hundred and eighty patients with cervical vertigo were divided into group A [acupuncture at R6nyfng （人迎ST 9） and Fengchi （风池 GB 20）, and frontal line], group B [acupuncture at Jing jiaji （颈夹脊）, GB 20 and Baihui （百会 GV 20）] and group C [intravenous infusion with ligustrazine and oral administration with flunarizine] according to simple randomization, with 60 cases in each group. For the patients in group A and group B, the treatment was conducted once a day, and ten times were considered as one course of treatment. Two days were free of treatment between two courses, and two courses were needed. For the patients in group C, the treatment was conducted for fifteen days. The contents of NPY, ET and CGRP in plasma before and after treatment were detected in patients with cervical vertigo. Results The contents of NPY in plasma of patients in the three groups after treatment were markedly lower than that before treatment （all P〈0.01）, and the differences were not statistically significant when compared the descending degrees among three groups （P〉0.05）. The contents of ET in plasma of patients in the three groups after treatment were markedly lower than that before treatment （P〈0.05, P〈0.01）, the descending degree in group A was greater than that in group B and group C, and the difference was statistically significant （P〈0.O1, P〈O.05）; while the difference was not statistically significant when compared the descending degrees between group B and group C （P〉0.05）. The contents of CGRP in plasma of patients in the three groups after treatment were markedly higher than that before treatment （P〈0.05, P〈O.O1）, the increasing degree in group A was greater than that in group B and group C, and the difference was statistically significant （both P〈0.05）; while the difference was not statistically significant when compared the increasing degrees between group B and group C （P〉0.05）. Conclusion Three vertigo-stopping needles, acupuncture and medication can regulate the contents of NPY, ET and CGRP in plasma of patients with cervical vertigo, while three vertigo-stopping needles is significantly superior to acupuncture and medication in reducing ET and increasing CGRP.

文摘Acupuncture at Fengchi（GB20） in the posterior neck improves vertigo.However,subarachnoid hemorrhage and spinal epidural hematoma have been reported to occur after acupuncture in the posterior neck.Therefore,in the present study,we assessed the safety of acupuncture at Fengchi.Laboratory tests and adverse event reports were used to evaluate the safety of different acupuncture manipulations for the treatment of posterior circulation ischemia with vertigo.A total of 136 patients were randomly assigned to four groups.Verum acupuncture was conducted with different needle insertion directions（contralateral paropia or prominentia laryngea） and different needle twisting frequencies（60 or 120 times/minute） at Fengchi and matching acupoints（for example,Zhongwan [CV12],Qihai [CV6],Zusanli [ST36],and Fenglong [ST40]）.The patients received 14 treatments over 3–4 weeks.Routine blood analysis,hepatic and renal function tests,urine and feces tests and electrocardiography were performed before the first treatment session and after the final session.Adverse events were recorded after every session.Of the 136 patients,120 completed the study.There were no significant differences between pretreatment and posttreatment test results in any of the groups.Only five patients suffered from minor adverse events（needling pain,slight hematoma and transient chest tightness）.No serious adverse events were found.Our results indicate that a 14-session course of needling at Fengchi is relatively safe for treating posterior circulation ischemia with vertigo.
文摘Benign paroxysmal positional vertigo(BPPV) is the most frequent episodic vestibular disorder. It is due to otolith rests that are free into the canals or attached to the cupulas. Well over 90% of patients can be successfully treated with manoeuvres that move the particles back to the utriculus. Among the great variety of procedures that have been described, the manoeuvres that are supported by evidenced-based studies or extensive series are commented in this review. Some topics regarding BPPV treatment, such as controlling the accuracy of the procedures or the utility of post-manoeuvre restrictions are also discussed.
文摘Benign paroxysmal positional vertigo(BPPV) is probably the most common diagnosis at vertigo clinics.Seasonal cycles of several human illnesses could be attributed variously to changes in atmospheric or weather conditions.In this retrospective study,patients with BPPV from January 2010 to December 2012 were studied,and their charts were reviewed.Statistical analysis revealed a statistically significant difference in patients’ numbers among different months of the year.Also there is a significant statistical correlation between the numbers of patients with climatic variations especially the temperature.The present paper discusses the possible explanations for these results which confirms the seasonal variations in BPPV,together with a review of literature to view the possible associations with other disorders that causes such seasonality.
文摘Objective:To investigate the efficacy of quick repositioning maneuver for horizontal semicircular canal benign paroxysmal positional vertigo (H-BPPV). Methods:Clinical data of 67 patients with H-BPPV who underwent quick repositioning maneuver in our hospital from July 2009 to November 2014 were retrospectively analyzed. The maneuver involved rotating the patient in the axial plane for 180? from the involved side towards contralateral side as quickly as possible. Results:Complete symptom resolution was achieved in 61 patients (91.0%) at one week and in 64 patients (95.5%) at 3 months post-treatment. During the repositioning maneuver process, there were no obvious untoward responses except transient nausea with or without vomiting in a few patients. Conclusion:The results indicate that the quick repositioning maneuver is an easy and effective alternative treatment in the management of H-BPPV. Copyright ? 2015 The Authors.

文摘The genesis of the Benign Paroxysmal Positional Vertigo(BPPV)seems to be related to some metabolic factors.These factors,such as vitamin D,glucocorticoids,and even thyroid and growth hormones,can affect bone metabolism and the mineralization of otoconia.It also seems to link to factors related to aging or nutritional habits.Besides,since the incidence of BPPV is quantitatively higher in women than in men,female sex steroids could be associated with this process.It could be useful to understand how these factors act in otoconial mineralization if we want to develop treatments aimed at preventing or delaying BPPV recurrences.In this review,we will analyze the role of these metabolic and hormonal factors in otoconial mineralization and in the treatment of BPPV.
文摘BACKGROUND Sudden hearing loss(SHL)is associated with serious systematic conditions such as neoplasms,vascular events,autoimmune diseases,infections,and iatrogenic injury.Some authors report that SHL can be an early warning sign of impending vertebrobasilar ischemic stroke.It is important to distinguish stroke from benign disease.CASE SUMMARY A 48-year-old male patient presented with SHL and vertigo as first symptoms.Diffusion-weighted imaging revealed high signal intensity in the left posterior inferior cerebellar artery territory of the cerebellar hemisphere and high signal intensity in the right pons and bridge cerebellar arm,confirming that the patient had cerebral infarction.Treatment with antiplatelet drugs,steroid antiinflammatory drugs,and neurotrophic nerve therapy promoted blood circulation and removed blood stasis,and the symptoms of the patient were significantly improved.CONCLUSION SHL and vertigo could be the initial symptoms of vertebrobasilar ischemic stroke.
文摘To evaluate the therapeutic efficacy of Yinxing Damo （银杏达莫, YXDM） combined with Betahistine Hydrochloride Injection （BHI） on vertebra basilar artery ischemic vertigo （VBIV）. Methods： Ninety patients with VBIV were randomly divided into two groups; 45 patients （the treated group） were treated with YXDM and BHI intravenous dripping, once a day for 14 days. Another 45 patients （control group） were treated with Xueshuantong （血栓通） and BHI intravenous dripping, once daily for 14 days. The clinical syndromes and the index of the transcranial Doppler （TCD） and hemorheology were observed. Results： The total effective rate was 100% in the treated group, which was better than that in the control group 90.5%, （P〈0. 05）. The indexes of TCD and hemorheology in the treated group were obviously improved after treatment, （P〈0.01）. Conclusion： YXDM combined with BHT injection had better effect in treating patients with VBIV is an ideal drug for VBIV.
文摘Background: Tympanomastoid paragangliomas are usually benign, slowly growing, painless tumors. The common presenting symptoms of this tumor are pulsatile tinnitus and conductive hearing loss. Vertigo as the cardinal or initial symptom is extremely rare, especially in the early stages of the disease.Case presentation: A 53-year-old female patient presented only with intermittent recurrent vertigo and was later found to have a tympanomastoid paraganglioma. Her symptoms disappeared completely after resection of the tumor. This is the first report in literature of a case of tympanomastoid paraganglioma with vertigo as the single symptom.Conclusion: The tympanomastoid paraganglioma is rare and its clinical symptoms are nonspecific, so it is easy to be misdiagnosed or missed. It is worth noting that although clinically uncommon, vertigo can also be the first or sole symptom of tympanomastoid paraganglioma. Detailed physical examination and imaging examination of the ear are necessary and should be carried out meticulously.
文摘One of the most common causes of vertigo is Benign Paroxysmal Positional Vertigo(BPPV),a sensation of spinning that is caused by a sudden change in head position.This type of vertigo was first described by Robert Barany in the early 1920s[1].He suggested that BPPV was caused by abnormal otoliths,also called statoconium or otoconius,a structure in the saccule or utricle in

文摘Background:Benign paroxysmal positional vertigo(BPPV)is characterized by vertigo lasting from seconds to minutes,induced by head movements.Objectives:Our study aimed to investigate the clinical significance of the caloric vestibular and video head-impulse tests(vHIT)diagnosing the disorder.Methods:68 patients suffering from posterior canal BPPV(25 male,43 females,mean age±SD,54.5±13.2 years)and 56 patients with a normal functioning vestibular system as control were investigated.Bithermal caloric test and vHIT was performed during the same medical check-up.Canal paresis(CP%),gain(GA)and asymmetry(GA%)parameters were calculated.Results:The Dix-Hallpike manoeuvre was only positive in 4%of this population.The CP%parameter was only pathologic in two patients,and there was no significant difference between control and BPPV patients(p=0.76).The GA value was never under 0.8 in this population,but GA%was abnormal in 63.2%.A significant difference comparing the GA%values to the control group was seen(p=0.034).There was no correlation detected between the CP%and GA%values in BPPV.Regarding the GA%value,61%sensitivity and 76%specificity was seen.Conclusion:The Dix-Hallpike manoeuvre was not often positive in the non-acute phase of BPPV;therefore,objective testing is essential.The caloric test does not have clinical significance in BPPV,but vHIT can be helpful based on the GA%parameter。
文摘Objective： To investigate the relationship among plasma endothelin（ET）, calcitonin gene-related peptide（CGRP） and blood flow rate of bilateral vertebral arteries in patients with cervical vertigo（CV） and to assess the effect of ET and CGRP on the onset of CV. Methods：The concentration of ET and CGRP in 64 patients with CV and 30 controls was determined by radioimmunity method. The average blood flow velocity （Vm） of bilateral vertebral arteries was detected by Transcranial Doppler（TCD）. Results：Plasma concen- tration ofET（91.48 ± 9.08 pg/ml） and ET/CGRP ratio value（2.88 ± 0.52） in vertebrobasilar arteriospasm group were both higher than those in vertebrobasilar non-arteriospasm group and in controls, while CGRP concentration（30.66 ± 6.05 pg/ml） in vertebrobasilar arteriospasm group was lower than that in vertebrobasilar non-arteriospasm group and controls respectively. The Vm of bilateral verte- bral arteries in vertebrobasilar arteriospasm group（67.97 ± 11.64 cm/s ） was higher than that in vertebrobasilar non-arteriospasm group and controls respectively, having a positive correlation with ET concentration and ET/CGRP ratio value（r1=0.52, P 〈 0.05; r2=0.59, P 〈 0.05）, but a negative correlation with CGRP concentration（r3=-0.54, P 〈 0.05）. There was no significant difference in ET and CGRP concentration, ET/CGRP ratio value and the Vm of bilateral vertebral arteries between vertebrobasilar non-arteriospasm group and the control group. Conclusion： All the results indicate that ET and CGRP are possibly the most important substance factors at the onset of CV with vertebrobasilar arteriospasm, and their imbalance of regulating vertebrobasilar arterial contraction and relaxation may play an important role in the onset of CV with vertebrobasilar arteriospasm.
文摘Objective To observe the clinical efficacy of needling Jingjiaji points in combination with acupressure for cervical vertigo, and provide a better therapy. Methods Sixty-five cases of patients with cervical vertigo were punctured on the points Jingjiaji and Fengchi （风池GB 20） bilaterally, from Qiangjian （强间 GV 18） to Naohu （脑户 GV 17）, from Yuzhan （玉枕 BL 9） to Tianzhu （天柱 BL 10） with penetrating methods, besides, acupressure was also used on these points. It was given once a day, and 16 times constituted one course with 2 courses altogether, and then the clinical efficacy was observed. Results Twenty-five cases were cured accounting to 38.5%; 18 remarkably improved accounting to 27.7%; 19 improved accounting to 29.2%; 3 ineffective accounting to 4.6%. The total effective rate was 95.4%. Conclusion Needling Jingjiaji points in combination with acupressure can alleviate the clinical symptoms of cervical vertigo and is worthy of being promoted.
文摘Introduction: The absence of vertigo during the caloric test, despite a robust response, has been suggested to represent a central vestibular system phenomenon. The purpose of this investigation was to determine the prevalence of absent caloric-induced vertigo perception in an unselected group of patients and to assess possible predicting variables.Methods: Prospective investigation of 92 unselected patients who underwent caloric testing. Inclusion criteria were that each patient generate a maximum slow phase velocity(maxSPV) > 15 deg/sec and a caloric asymmetry of≤10%. Following the caloric, patients were asked, "Did you have any sensation of motion?"Results: Results showed 75% of patients reported motion with a mean age of 56.51 years compared to a mean age of 66.55 in the 25% of patients reporting an absence of motion. A logistic regression was performed and the overall model was statistically significant accounting for 29% of the variance in caloric perception. The significant predictor variables were patient age and maxSPV of the caloric response. The effect size for both variables was small with an odds ratio of.9 for maxSPV and 1.06 for age.Conclusions: The current investigation showed that both age and maxSPV of the caloric response were significant predictors of vertigo perception during the caloric exam. However, the association between age and caloric perception is not conclusive. Although there is evidence to suggest that these findings represent age-related changes in the central processing of vestibular system stimulation, there are additional unmeasured factors that influence the perception of caloric-induced vertigo.
