OBJECTIVE: To investigate the effect of electroacupuncture on mRNA expression of NGF and IGF-1 in injured nerve. METHODS: Sciatic nerve injury model was established by transection of right side sciatic nerve in 90 male SD rats, which were randomly divided into two groups. The experimental group was treated with electroacupuncture, no treatment in the control group. The distal part of the injured nerve was harvested after 1, 2, 4, 6 and 10 weeks of operation and stored in the liquid nitrogen. The total RNA was extracted by the TRIzol reagent. Reverse transcriptase-polymerase chain reaction(RT-PCR) was used to detected the mRNA expression of NGF and IGF-1. RESULTS: The mRNA expression of NGF in the experimental group was increased quickly from the second week, and reached to highest level in the fourth week. It was much higher than that of the control group (P lt; 0.05). Then it began to decline in following time and approximately reached to the level of the first week after 10 weeks of operation. The mRNA expression of IGF-1 in the experimental group was remarkably increased in the second and fourth week, and which was much higher than that of the control group respectively(P lt; 0.05). Although the mRNA expression of IGF-1 after 10 weeks of operation in the experimental group was higher than that of the control group, but there was no significant difference between the two groups(P gt; 0.05). There was linear correlation in the fourth week between mRNA expression of NGF and IGF-1 in the experimental group. CONCLUSION: The mRNA expression of NGF and IGF-1 can be elevated in injured nerve at early stage interfered with electroacupuncture.
Six patients with moderate to advanced primary carcinoma of the liver were treated in this hospital with perfusion chemotherapy and embolization through the regional portal vein under the guidance of B-ultrasongraph rather than (with) operatie catheteization of the portal vein. The results show that all the tumor masses were reduced in size after the treatment (1.2-3.2cm, average value 1.9cm). It might be a new way for treating the primary carcinom of liver. The detailed procedure is descibed and the effects are also discussed in this article.
ObjectiveTo evaluate the feasibility and short-term effectiveness of bilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach for osteoporotic vertebral compression fracture (OVCF) of lumbar.MethodsA retrospective analysis was made on the clinical data of 93 patients with OVCF of lumbar who met the selection criteria between January 2018 and June 2019. According to the different surgical methods, they were divided into group A (44 cases, treated with bilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach) and group B [49 cases, treated with percutaneous kyphoplasty (PKP) via bilateral transpedicle approach]. There was no significant difference in gender, age, body mass index, T value of bone mineral density, injury cause, fractured level, time from injury to operation, comorbidities, and preoperative Cobb angle of injured vertebra, visual analogue scale (VAS) score, and Oswestry disability index (ODI) between the two groups (P>0.05). The operation time, intraoperative fluoroscopy times, bone cement injection amount, and incidence of bone cement leakage were recorded and compared between the two groups; Cobb angle of the injured vertebrae, VAS score, and ODI were measured before operation, at 2 days and 1 year after operation. The contralateral distribution ratio of bone cement was calculated according to the anteroposterior X-ray film at 2 days after operation.ResultsThe operation time and the intraoperative fluoroscopy times in group A were significantly less than those in group B (P<0.05). There was no bone cement adverse reactions, cardiac and cerebrovascular adverse events, and no complications such as puncture needles erroneously inserted into the spinal canal and nerve injuries occurred in the two groups. Bone cement leakage occurred in 6 cases and 8 cases in groups A and B, respectively, all of which were asymptomatic paravertebral or intervertebral leakage, and no intraspinal leakage occurred; the bone cement injection amount and incidence of bone cement leakage between the two groups showed no significant differences (P>0.05). The contralateral distribution ratio of bone cement in group A was significantly lower than that in group B (t=2.685, P=0.009). Patients in both groups were followed up 12-20 months, with an average of 15.3 months. The Cobb angle of the injured vertebrae, VAS score, and ODI in the two groups were significantly improved at 2 days after operation, however, the Cobb angle of the injured vertebra at 1 year after operation was significantly lost when compared with the 2 days after operation, the VAS score and ODI at 1 year after operation were significantly further improved when compared with the 2 days after operation, the differences were all significant (P<0.05). There was no significant difference in the Cobb angle of the injured vertebrae, VAS score, and ODI between the two groups at each time point after operation (P>0.05).ConclusionBilateral percutaneous balloon kyphoplasty through unilateral transverse process-extrapedicular approach is comparable to bilateral PKP in short-term effectiveness with regard to fracture reduction, reduction maintenance, pain relief, and functional improvement. It has great advantages in reducing operation time and radiation exposure, although it is inferior in bone cement distribution.
Objective To investigate the combined effects of digastric muscle low frequency modulated medium frequency electro-acupuncture therapy and voice training for dysphagia in patients who underwent aortic arch surgery. Methods Forty-two consecutive patients with dysphagia after aortic arch surgery between October 2014 and November 2017 were divided into two groups including an observation group and a control group. There were 21 patients in each group. There were 17 males and 4 females at age of 51.0±6.5 years in the observation group, while 18 males and 3 females at age of 49.8±7.3 years in the control group. The patients in the observation group underwent electroacupuncture therapy and voice training (20 min per day for each therapy, 2 weeks), while the patients in the control group only received safe swallowing education and rehabilitation guidance (2 weeks). The test results, such as fibrolaryngoscope and functional oral intake scale (FOIS) score, and the data of computer phonatory detection, before and after the intervention were compared. Results The fibrolaryngoscope of vocal cords significantly decreased and the FOIS score significantly increased after digastric muscle low frequency modulated medium frequency electro-acupuncture therapy and voice training in the observation group(6.30 vs. 4.60, P<0.05). Bucking was obviously reduced. The indicators of hoarse degree, such as median pitch, fundamental frequency, jitter (0.60%±0.96%vs. 1.99%±1.86%, P=0.033), shimmer (2.47%±4.26% vs. 5.89%±3.66%, P=0.043), maximum phonation time (15.31±9.10 s vs. 3.72±8.83 s, P=0.006), maximum and loud phonation time (9.30±5.73 s vs. 2.32±2.99 s, P=0.039), mean noise-to-harmonics ratio (23.99±10.17 vs .9.98±9.37, P=0.006) and mean harmonics-to-noise ratio (0.03±0.02 vs. 0.17±0.23, P=0.019) improved after the treatment in both groups. But the improvement in the observation group was significantly better than that in the control group. Conclusion The combination of digastric muscle low frequency modulated medium frequency electro-acupuncture therapy and voice training on dysphagia in patients who underwent aortic arch surgery can significantly improve the swallowing function of patients. Meanwhile, it also helps the recovery of phonic function and improves the ability of feeding and communication in these patients.
Objective To explore the feasibility and effectiveness of vertebroplasty with reverse designed unilateral targeted puncture in treatment of osteoporotic vertebral compression fracture (OVCF) by comparing with curved unilateral puncture. Methods A total of 52 patients with OVCF met selection criteria and were admitted between January 2019 and June 2021 were selected as the research objects. According to the random number table method, they were divided into two groups (n=26). In trial group, the reverse designed unilateral targeted puncture was used in the percutaneous vertebroplasty (PVP); while the control group used the curved unilateral puncture. There was no significant difference in gender, age, bone mineral density (T value), cause of injury, time from injury to operation, the level of responsible vertebral body, pedicle diameter of the planned puncture vertebral body, and preoperative visual analogue scale (VAS) score, anterior vertebral height, and Cobb angle between the two groups (P>0.05). The operation time, bone cement injection volume and leakage, intraoperative radiation exposure times, and hospitalization costs in the two groups were recorded. VAS score was used to evaluate the relief degree of low back pain after operation. X-ray film was used to review the diffusion degree of bone cement in the responsible vertebral body, and Cobb angle and anterior vertebral height were measured. Results The operation was successfully completed in the two groups. Patients in the two groups were followed up 12-18 months, with an average of 13.6 months. The operation time, volume of injected bone cement, intraoperative radiation exposure times, and hospitalization costs in the trial group were significantly lower than those in the control group (P<0.05). With the prolongation of time, the low back pain of the two groups gradually relieved, and the VAS score significantly decreased (P<0.05). And there was no significant difference in VAS score between the two groups at each time point (P>0.05). There were 2 cases (7.6%) of bone cement leakage in the trial group and 3 cases (11.5%) in the control group, and no significant difference was found in the incidence of bone cement leakage and the diffusion degree of bone cement between the two groups (P>0.05). Imaging examination showed that compared with pre-operation, the anterior vertebral height of the two groups significantly increased and Cobb angle significantly decreased at 2 days and 1 year after operation (P<0.05); while compared with 2 days before operation, the anterior vertebral height of the two groups significantly decreased and Cobb angle significantly increased at 1 year after operation (P<0.05). There was no significant difference in the above indexes between the two groups at different time points after operation (P>0.05). Conclusion Compared with curved unilateral puncture, the use of reverse designed unilateral targeted puncture during PVP in the treatment of OVCF can not only achieve similar effectiveness, but also has the advantages of less radiation exposure, shorter operation time, and less hospitalization costs.
Objective To summarize the recent minimally invasive approach for cervical spondylotic radiculopathy (CSR). Methods The recent l iterature at home and abroad concerning minimally invasive approach for CSR was reviewed and summarized. Results There were two techniques of minimally invasive approach for CSR at peresent: percutaneous puncture techniques and endoscopic techniques. The degenerate intervertebral disc was resected or nucleolysis by percutaneouspuncture technique if CSR was caused by mild or moderate intervertebral disc herniations. The cervical microendoscopicdiscectomy and foraminotomy was an effective minimally invasive approach which could provide a clear view. The endoscopy techniques were suitable to treat CSR caused by foraminal osteophytes, lateral disc herniations, local l igamentum flavum thickening and spondylotic foraminal stenosis. Conclusion The minimally invasive procedure has the advantages of simple handl ing, minimally invasive and low incidence of compl ications. But the scope of indications is relatively narrow at present.
Objective To evaluate the effectiveness of percutaneous puncture of thoracolumbar vertebral pedicle assisted by mixed reality technology based on multi-point registration algorithm. Methods The operator used two methods, namely MR-assisted puncture (a self-developed MR calibration method based on multi-point registration algorithm combined with MR head mounted equipment) and manual puncture, to perform percutaneous puncture of the thoracolumbar pedicle on the spinal prosthesis model. The distance between the first blind puncture point and the preset nail center point, and single registration and puncture time were compared among different puncture methods. Results Four operators completed a total of 48 MR-assisted punctures and 48 manual punctures. The deviation distance of MR-assisted puncture [(1.69±0.29) vs. (4.99±2.06) mm], registration and puncture time [(131.41±5.35) vs. (475.98±65.26) s] were all better than manual puncture (P<0.05). Conclusion The prosthetic model data shows that MR technology-assisted puncture based on multi-point registration algorithm can improve the accuracy and efficiency of percutaneous puncture of thoracolumbar vertebral pedicle compared to traditional manual puncture.
Objective To examine the efficacy of acupuncture in hastening recovery and reducing long-term morbidity from Bell’s palsy. Methods We searched the Cochrane Neuromuscular Disease Group Register Group (Till Feb. 2002), MEDLINE (Jan. 1966 to Dec. 2002); EMBASE (Jan. 1980 to Dec. 2002), LILACS (Jan. 1982 to Dec. 2002) and Chinese Biomedical Retrieval System (Jan. 1978 to Dec. 2002). We also searched grey literature. We identified all randomised or quasi-randomised controlled trials involving acupuncture in the treatment of Bell’s palsy, selected the trials ment the inclusion criteria, assessed the methodological quality, extracted data on trials’ patients, interventions, outcome measurements and results and undertook analysis. Results Three small randomised controlled trials were included but due to some flaws in study designs or reporting and clinical differences between trials, data from trials were not combined in a meta-analysis，and a descriptive analysis was performed.The result indicated a positive effect of acupuncture (all Plt;0.01). Conclusions Three small studies in this review suggested a beneficial effect but the poor quality of the trials precludes us from drawing firm conclusions. There is a need for high quality randomized controlled trials (RCTs) using a study design which assures high internal validity.
Objective To systematically review the efficacy and safety of acupuncture for the treatment of tumor-related cognitive dysfunction. Methods The PubMed, The Cochrane Library, EMbase, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect studies on acupuncture for the treatment of tumor-related cognitive dysfunction from the establishment of the database to February 13th, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4.1 software. Results A total of 16 studies involving 1 361 patients were included. The results of meta-analysis showed that the mini-mental state examination (MD=1.82, 95%CI 1.49 to 2.15, P<0.000 01) and Montreal cognitive assessment (MD=1.56, 95%CI 0.83 to 2.29, P<0.0001) scores of the acupuncture treatment group were superior to those in the control group. Furthermore, the acupuncture treatment group showed a reduced incidence of postoperative cognitive dysfunction (RR=0.50, 95%CI 0.39 to 0.63, P<0.000 01) and decreased levels of interleukin-6 (MD=?10.43, 95%CI ?14.91 to ?5.95, P<0.000 01), interleukin-1β (MD=?47.14, 95%CI ?63.92 to ?30.36, P<0.000 01), and tumor necrosis factor-α (MD=?9.13, 95%CI ?12.38 to ?5.89, P<0.000 01). In contrast, the visual analog scale score of the acupuncture treatment group (MD=?1.26, 95%CI ?2.06 to ?0.47, P=0.002) was better than that of the control group. No significant difference was found in the level of central nervous system-specific protein (S100β) (MD=?0.06, 95%CI ?0.13 to 0.01, P=0.12) between the two groups. Conclusion Acupuncture therapy can improve tumor-related cognitive function in patients. Its curative effect is better than that of non-acupuncture therapy; however, its ability to reduce S100β levels is not significantly different from that of non-acupuncture therapy. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objectives We aimed to assess the methodological qual ity of RCT on acupuncture for migraine prophylaxis. Methods With the searching terms including acupuncture, migraine, prophylaxis and prevent, etc, the database of the Cochrane Library (Issue 4, 2007), MEDLINE (1966-2007), EMBase (1966-2007), CBM (1978-2007) and CMCC (1994-2007) were searched from their date of start publ ication. Chinese medical journals and relevant academic conference proceedings were hand searched as well. Several items in included trials were assessed, including methodology, diagnostic criteria, inclusion/exclusion criteria, acupuncture/control interventions, outcome measures and follow-up, etc. Result Among the 12 included trials, 9 trials overseas were high-qual ity and 3 in China were low-quality. Frequency or days of migraine attacks and SF-36/SF-12 were often evaluated as outcome measures in western countries, while headache index was used in China. Among the 12 trials, 9 reported the follow-up outcomes and 8 mentioned adverse events. Conclusion There was no high qual ity trial on acupuncture for migraine prophylaxis in China. The outcome measures in trials published in China by now can not evaluate the outcomes of acupuncture for migraine prophylaxis accurately. To study designs, advantages of trials oversea can be used for reference. To Chinese cl inical physicians, prophylactic therapy and abortive therapy of migraine should be distinguished in order to design high-qual ity study on acupuncture for migraine prophylaxis.
