Objective:To investigate the clinical efficacy of acupuncture combined with massage on cervical spondylopathy of vertebral artery type and its effect on hemodynamics of patients.Methods:Sixty patients with vertebral artery type cervical spondylosis treated in our hospital from July 2017 to October 2019 were selected as the research subjects and randomly divided into 2 groups of 30 cases each.The control group was treated with acupuncture,and the observation group was treated with acupuncture combined with massage,and the clinical efficacy and hemodynamic index of the two groups were compared after 1 month of treatment[peak systolic blood velocity(PSV),pulsatile index(PI),time mean flow velocity(TMFV)].Results:There was no statistical difference in the PSV,PI,and TMFV between the two groups before treatment(P>0.05).After treatment,the observation group had a higher treatment efficacy than the control group with PSV and TMFV increasing and PI decreasing in both groups,and the change in the observation group was greater than that in the control group,and the difference was statistically significant(P<0.05).Conclusion:Acupuncture combined with massage on cervical spondylopathy of vertebral artery type can improve the clinical efficacy and improve the hemodynamic index of patients,which is worthy of clinical application.

Acupuncture-based treatments on cervical spondylosis of vertebral artery type

Cervical spondylosis of vertebral artery type is one of the chief patterns of cervical spondylosis.It is often described as neck pain accompanied with radiating pain and neurologic symptoms,such as sudden dizziness,blurred vision,tinnitus,nausea,vomiting,memory loss,and sudden fainting.The incidence of cervical spondylosis increases and patients with cervical spondylosis become progressively younger.Acupuncture in the cervical spondylosis of vertebral artery type treatment has a local positive reaction“Liuhe point”,in order to dredge the local Qi and blood.More and more evidences into the effectiveness and safety of cervical spine acupuncture for cervical spondylosis,specific neck pain,cervical radiculopathy,etc.This article summarizes the recent literature on acupuncture and acupuncture combined with other therapies for cervical spondylosis of vertebral artery type treatment and provides a comprehensive review from the perspectives of acupuncture therapy,warm needle moxibustion therapy,electroacupuncture,and acupuncture combined with other therapies,in order to provide reference and reference for clinical treatment.

Acupuncture of different stimulation for the treatment of neck type cervical spondylosis:a randomised controlled trial

Objective:To observe the difference in clinical efficacy of acupuncture with strong and weak stimulation in treating neck type cervical spondylosis.Methods:64 patients with neck type cervical spondylosis were randomly divided into strong stimulation group and weak stimulation group,with 32 cases in each group.The acupoints selected are Jingjiaji 5-7(cervical acupoints EX-B2 C5-C7),Tianzhu(BL10)on both sides,Houxi(SI3)on both sides,Hegu(LI4)on both sides,Geshu(BL17)on both sides,and Ashi.In the strong stimulation group,deep needling with 0.25 mm×40 mm milli-needle was performed,with a mild reinforcing-reducing method.The twisting angle was 90°-180°,the frequency was 60-90 times/min,and the needles were applied for 1 min at each point.Keep the needle for 30 minutes,twisting was performed every 10 min during the retention period.Change hands once.In the weak stimulation group,shallow acupuncture with a 0.18 mm×40 mm milli-needle was performed,with a mild reinforcing-reducing method,with a twisting angle of 60°-90°,a frequency of 30-60 times/min,and acupuncture for 10 seconds at each acupoint.Keep the needle for 30 minutes,and no needle during the retention period.Patients in both groups were treated once every 1 to 2 days,3 times a week for 2 weeks,and followed up for 1 month after all treatments.The two groups of patients were compared before and after treatment and during follow-up.The McGill pain questionnaire score and the cervical spine dysfunction index score were compared to determine the clinical efficacy.Statistical analysis was performed using SPSS 22.0 statistical software.Results:1 case drop-out in the strong stimulation group and 1 case in the weak stimulation group.The total effective rate of the strong stimulation group was 90.32%,the total effective rate of the weak stimulation group was 83.87%,and the total effective rate of the strong stimulation group was higher than that of the weak stimulation group(P<0.05).The total scores of the short-form McGill pain questionnaire,the VAS score,and the cervical spine dysfunction index scores of the two groups of patients were significantly lower than those of this group before treatment,and the difference was statistically significant(P<0.05).The total scores of the short-form McGill pain questionnaire,visual analogue scale score,and cervical spine dysfunction index scores of the strong stimulation group after treatment and follow-up were significantly lower than those of the weak stimulation group(P<0.05).Conclusion:Acupuncture with strong and weak stimulation can effectively treat patients with cervical spondylosis,and deep acupuncture with filiform needles and strong stimulation have better effect.

Polymorphism in the upstream regulatory region of human papilloma virus type 16 from the cervical cancer biopsies in Xinjiang Uygur women

To investigate the mutations in the upstream regulatory region (URR) of human papillomavirus type 16 (HPV-16) from the cervical cancer biopsies in Xinjiang Uygur women and its relationship to the high incidence of cervical cancer in the southern Xinjiang, the tissue DNA was extracted from the cervical cancer biopsies, and the URR segment of HPV-16 DNA was amplified, sequenced and analyzed. Thereafter, the polymorphism of URR in HPV-16 was then analyzed. It was demonstrated that the positive rate detected for the presence of URR in HPV-16 was 89.47% (17/19). Compared with the previously published sequence in URR of prototype HPV-16, some mutations were detected in the sequence of URR. The mutations in 17 URR fragments of HPV-16 could be divided into 11 patterns (XJU-1 to XJU-11) at nucleic acid level, in which each of XJU-1 and XJU-4 accounted for 23.53% (4/17), and other patterns of mutation accounted for 5.88% (1/17) . In comparison with the URR of prototype HPV-16, the DNA identity of these patterns was 98.50%-99.68% . In these 17 URR fragments, two point mutations occurred at position 7192 (G to T) and position 7520 (G to A) and they appeared to be constant in Xinjiang area. These two mutations were ubiquitous in the Asia-American type and conferred strong infection activity and carcinogenicity of this virus. In addition, the mutations at position 7729 (A to C), position 7843 (A to G) and position 7792 (C to T) could enhance its transcription activity considerably. It is concluded that some mutations occur in URR gene of HPV-16 in the cervical cancer biopsies taken from Uygur women in Xinjiang area, suggesting that certain relationship exists among the mutations in URR of HPV-16, the phylogeny of HPV-16 and the high incidence of cervical cancer in southern part of Xinjiang area.

A CLINICAL OBSERVATION ON THE THERAPEUTIC EFFECT OF CERVICAL SPONDYLOPATHY OF NERVE ROOT TYPE TREATED BY COMBINED CERVICAL TRACTION AND ELECTROACUPUNCTURE

Objective: To observe the therapeutic effect of combined cervical traction and electroacupuncture (EA) on Cervical Spondylopathy of Nerve Root Type (CSNRT). Methods: 145 patients diagnosed as CSNRT were randomized into 3 groups: combined treatment group, EA group, and cervical traction (CT) group. The combined group was treated with traction followed by EA of Dazhui (大椎 GV 14), Fengchi (风池 GB 20), cervical Jiaji (夹脊 EX-B 2), etc.. Patients of two control groups were only treated by either CT or EA. Results: The markedly-effective rate and total effective rate were 76.0% and 94.0% respectively in the combined treatment group, 62.5% and 81.25% respectively in CT group, and 63.82% and 82.97% respectively in EA group. The therapeutic effect of the combined treatment group was significantly superior to that of two control groups (P<0.05). At 6-month follow-up, the above two markedly-effective and total effective rates in the combined treatment group remained 74.0% and 92.0%, still significantly higher than that in two control groups. Conclusion: Combining cervicle traction with EA treatment can effectively eliminate or relieve the symptoms and signs in patients with nerve root type cervical spondylopathy.

Methods According to the random number table, 150 cases of cervical spondylosis of nerve root type were randomized into an acupuncture-moxibustion group （75 cases） and a control group （75 cases）. In the acupuncture-moxibustion group, the warm needling at EX-B 2 and tapping with plum-blossom needle were applied. EX-B 2 on the affected segments were selected and stimulated with warm needling technique for 20– 30 min. Afterward, the plum-blossom needle was used to tap the skin around the acupoints, for 3 min on each site. The treatment was given once every day. Seven treatments made one session. The interval between two sessions was 1 day. In the control group, the medication was used in combination with traction therapy. The intravenous drip with 5% glucose 250 mL and compound salvia miltiorrhiza injection 40 mL was used, once a day. In traction treatment, the patient was in a sitting position, neck anteflexion at 15°–30°, traction force at 10%–20% of the body mass, for 20–30 min in each time. The treatment was given once every day. The appointed person evaluated therapeutic effects after the three sessions of treatment in the two groups. Results The clinical curative rate was 49.3% （37/75） and the total effective rate was 94.7% （71/75） in the acupuncture-moxibustion group and those were 24.0% （18/75） and 81.3% （61/75） respectively in the control group. The total effective rate and clinical curative rate in the acupuncture-moxibustion group were superior to the control group （both P0.05）. In the comparison of the duration of treatment and effect in the cured patients between the two groups, the curative rate in the 1st session of treatment in the acupuncture-moxibustion group was higher than that in the control group （P0.05）. In the comparison of the 6-month follow-up visit in the cured patients between the two groups, the effect in the acupuncture-moxibustion group was much more stable （P0.05）. Conclusion The warm needling therapy at EX-B 2 and tapping therapy with plum-blossom needle achieve the significant effect on cervical spondylosis of nerve root type.

Efficacy observation on cervical spondylosis of vertebral artery type treated with warm needling and rehabilitation physiotherapy therapy

Objective To compare the differences in the efficacy on cervical spondylosis of the vertebral artery type （CSA） treated with the warm needling therapy combined with the rehabilitation physiotherapy, the simple warm needling therapy and the simple rehabilitation physiotherapy separately and observe the impacts of them on the vertebral basilar artery （VBA） in hemodynamics. Methods Ninety cases of CSA patients were randomized divided into an acupuncture plus rehabilitation group, a warm needling group and a rehabilitation group, 30 cases in each. In the acupuncture ＋ rehabilitation group, the warm needling therapy was used at Jiájǐ （夹脊 EX-B 2） from C3 to C7 in combination with the rehabilitation physiotherapy such as traction and magnetic therapy. In the warm needling group, the simple warm needling therapy was applied. In the rehabilitation group, the simple rehabilitation physiotherapy was adopted. The VBA hemodynamic parameters, Vp, Vd, Vm and PI values were detected under the transcranial Doppler and taken as the indexes for the efficacy assessment of the groups. The efficacy of each group was assessed in association with the clinical curative rate. Results After treatment, the VBA hemodynamic parameters, Vp, Vd, Vm and PI values were all remarkably improved as compared with those before treatment in the three groups （P〈0.01, P〈0.05）. The improvement of the indexes in the acupuncture plus rehabilitation group were more significant as compared with either of the other two groups （all P〈0.01）. The clinical curative rate was 70.0% （21/30） in the acupuncture plus rehabilitation group, which was superior to 53.3% （16/30） in the warm needling group and 53.3% （16/30） in the rehabilitation group （all P〈0.01）. Conclusion The warm needling in combination with the rehabilitation physiotherapy significantly improves in VBA hemodynamic parameters for CSA and its clinical efficacy is superior to either the simple warm needling or the rehabilitation physiotherapy. Hence, this combined therapy was highly deserved to be promoted in clinical practice.
