Efficacy of five-step shoulder manipulation for rotator cuff-related shoulder pain: protocol for a multicenter randomized controlled trial.

BACKGROUND: Rotator cuff-related shoulder pain (RCRSP) is the most common cause of shoulder disorders. In China, manipulation has been used extensively for the treatment of patients with RCRSP. However, high-quality clinical evidence to support the therapeutic effect of manipulation is still limited. METHODS: A multicenter, participant-, outcome assessor-, and data analyst-blinded, randomized, placebo-controlled trial will be conducted. A total of 280 participants with RCRSP will be recruited from three hospitals and randomly assigned to a five-step shoulder manipulation (FSM) group or a sham manipulation (SM) group. Each group will receive four weekly treatment sessions, with all participants performing exercises at home for 12 weeks. Assessments, namely the Constant-Murley score, visual analog scale, range of motion, and 36-Item Short Form Survey, will be made at baseline, 4, 12, 18, and 24 weeks. Adverse events during the study will also be recorded. DISCUSSION: This is a pragmatic clinical trial to evaluate the efficacy and safety of FSM in patients with RCRSP. The findings of this study will provide worthy clinical evidence for manual therapy for RCRSP. TRIAL REGISTRATION: China Registered Clinical Trial Registration Center ChiCTR2000037577.

[GAO Wei-bin's clinical experience in treatment of medulla oblongata paralysis with nape acupuncture].

This paper introduces GAO Wei-bin's academic thought in treatment of medulla oblongata paralysis with acupuncture. Through analyzing the etiologies and locations of medulla oblongata paralysis, in accordance with "selecting the nearby acupoints of the affected area", the acupoints are selected from the nape region, the nape acupuncture therapy and the corresponding new points are developed. Based on the human anatomy of the nape region, the anatomic structures of new points (e.g. Gongxue, Tunyan-1, Tunyan-2, Fayin, Zhiqiang and Tiyan) and their effect mechanism are explained. The treatment principle, "distinguishing the symptoms from the root causes, mutual treatment for both symptoms and root causes", is proposed, and the importance of electric stimulation of nape acupuncture is suggested in treatment of medulla oblongata paralysis.

[Head acupuncture combined with exercise therapy for nonspecific low back pain：a randomized controlled trial].

OBJECTIVE: To compare the clinical effect between head acupuncture combined with exercise therapy and conventional acupuncture for nonspecific low back pain. METHODS: A total of 64 patients with nonspecific low back pain were randomized into an observation group (32 cases, 2 cases dropped off) and a control group (32 cases, 2 cases dropped off). In the control group, conventional acupuncture was applied at Jiaji (EX-B 2) of L1 to L3, ashi point, Shenshu (BL 23), Dachangshu (BL 25), Yaoyangguan (GV 3) and Weizhong (BL 40). The observation group was treated with head acupuncture combined with exercise therapy, head acupuncture was applied at foot-motor-sensory area on the healthy side and Cuanzhu (BL 2), Tongziliao (GB 1) on the affected side, and McKenzie therapy was performed during retention. The needles were retained for 40 min, once a day, continuous treatment for 6 days with the interval of 1 day, 14 days were required in the two groups. Before and after treatment, the pain visual analogue scale (VAS) score, Oswestry disability index (ODI) score and infrared thermography temperature of pain area in the low back were compared in the two groups. RESULTS: Compared before treatment, the VAS and ODI scores after treatment were decreased in the two groups (P<0.01), and those in the observation group were lower than the control group (P<0.01). Compared before treatment, the infrared thermography temperature of pain area in the low back after treatment was increased in the two groups (P<0.01), and that in the observation group was higher than the control group (P<0.01). CONCLUSION: Head acupuncture combined with exercise therapy could relieve pain, improve dysfunction and increase the local temperature of pain area in patients with nonspecific low back pain, and its curative effect is better than conventional acupuncture.

Non-surgical treatment with XSHHD for ruptured lumbar disc herniation: a 3-year prospective observational study.

BACKGROUND: Lumbar disc herniation (LDH) is mainly caused by annular fiber disruption with a discrete leakage of nucleus pulposus pressing on a nerve, resulting in back pain and radiating pain. Most patients with LDH can be treated conservatively, but there are many different conservative treatments. Furthermore, most previous studies did not evaluate the long-term efficacy of these treatments and the prognosis. Therefore, an effective and safe therapeutic strategy is lacking for patients with LDH. In this study, we evaluated Xiao Sui Hua He decoction (XSHHD) in the treatment of LDH. METHODS: This was a rigorous prospective observational 3-year follow-up study. We recruited 69 participants with ruptured lumbar disc herniation (RLDH) between February 2014 and February 2016. Patients took XSHHD orally twice a day for 6 months. The primary outcome measurements were visual analogue scale (VAS) pain score, Oswestry disability index (ODI) and straight leg raising test (SLRT). The secondary outcome measurements was nucleus pulposus protrusion volume on magnetic resonance imaging (MRI). Clinical outcomes were measured at baseline (Visit 1), and at 3, 6, 12, and 36 months (Visit 2, 3, 4, and 5, respectively).. RESULTS: Sixty-three patients were followed-up for 3 years after treatment. SLRT and ODI after non-surgical treatment improved significantly compared with baseline (P < .001). There were no statistically significant differences at 6 months vs 36 months for SLRT and ODI. VAS scores (leg, back) after 3 years of treatment were statistically significantly different compared with baseline (P < .001; Z = - 6.93, - 6.637). The baseline protrusion volume was 2018.61 ± 601.16 mm3, and the volume decreased significantly to 996.51 ± 387.42 mm3 at 36 months (t = 12.863; P < .001). The volume of protrusion resorption rate (VPRR) at 36 months was 47.24 ± 23.99%, with significant resorption in 23 cases, partial resorption in 23 cases, no resorption in 15 cases, and increased volume in 2 cases. CONCLUSIONS: This study showed that non-surgical treatment with XSHHD was effective, and the study clarified the natural outcomes in LDH.

Spraying rhubarb powder solution under gastroscope in the treatment of acute non-varicose upper gastrointestinal bleeding: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: Systematically assessing the safety and effectiveness of spraying rhubarb powder solution under gastroscope for the treatment of acute non-varicose upper gastrointestinal bleeding, and confirmation for further clinical research and application. METHODS: We searched the following databases up till November 2019: PubMed, the Cochrane Library, EMBASE, CNKI, WanFang Data, VIP and SinoMed. Randomized controlled trials (RCTs) were used to compare the curative effect of spraying rhubarb powder solution with other drugs under gastroscope for the treatment of acute non-varicose upper gastrointestinal bleeding. RESULTS: Out of 171 articles, 14 RCTs involving 1493 patients were included. All control groups included in the RCTs were treated with norepinephrine solution. The hemostatic effect of spraying rhubarb powder solution under gastroscope was examined for 24 h at high concentration (0.1 g/mL). The hemostatic effect at higher conc. (0.1 g/mL) found far more better than low conc.(RR = 1.48;95 %CI:1.25,1.75;P﹤0.00001) (0.03 g/mL)as homeostatic effect at low conc.is same that of norepinephrine solution (RR = 1.02;95 %CI:0.94,1.10;P = 0.62). Moreover within 48 h, rhubarb powder solution with 0.1 g/mL or 0.15 g/mL conc. have of significantly higher hemostatic effects than norepinephrine solution (RR = 1.18;95 % CI: 1.08, 1.30;P = 0.0003). Occurrence of rebleeding event within 48 h after successful hemostasis (RR = 0.42;95 %CI:0.24,0.74;P = 0.003) reduced exceptionally. After that the hemostatic effect of rhubarb powder solution with 0.1 g/mL conc.examined within 72 h again exhibited significant improvement than norepinephrine solution (RR = 1.19;95 %CI:1.12,1.26;P < 0.00001). On par with immediate hemostasis time, rhubarb powder solution took unprecedented less time than norepinephrine solution;(MD=-5.56S;95 %CI:-6.16, -4.95;P﹤0.00001). Additionally, the adverse reaction produced by rhubarb powder solution is much lower than norepinephrine solution (RR = 0.22;95 %CI:0.11,0.42;P < 0.00001). CONCLUSIONS: According to meta-analysis, Spraying rhubarb powder solution under gastroscope in the treatment of acute non-varicose upper gastrointestinal bleeding is superior to norepinephrine solution in improving hemostasis effect. Shortening immediate hemostasis time and reducing rebleeding,and is safe to use. Based on the results of this study, physicians can treat patients with acute non-varicose upper gastrointestinal bleeding by spraying rhubarb powder solution under gastroscope according to the patients' condition.However, the sample size included in this study is small and of substandard quality qu, and a large sample size clinical trial with strict design and normative report is needed to verify the safety and efficacy of rhubarb powder solution under gastroscope for acute non-varicose upper gastrointestinal bleeding.

[Limited external fixation of plastic cardboard for the treatment of senile comminuted humeral fracture].

OBJECTIVE: To explore clinical efficacy of limited external fixation with plastic paperboard in treating senile proximal comminuted humeral fracture. METHODS: From June 2015 to December 2017, 32 senile patients with proximal comminuted fracture of humerus were treated with plasticized cardboard after manual external fixation. Among them, including 13 males and 19 females aged from 55 to 85 years old with an average of(68.22±8.36) years old; 18 patients on the left side and 14 patients on the right side; all patients were regularly review shoulder X-rays and performed appropriate functional exercises. Constant-Murley shoulder joint scoring was used to evaluate clinical effects. RESULTS: Thirty-two patients were followed up for 3 to 12 months with an average of (4.97±2.39) months. All patients were underwent functional exercise under guidance of physicians. Nine patients were treated with topical Chinese herbal moist heat compresses to promote shoulder function recovery. Thirty-one patients were obtained fracture healing, the time ranged from 5 to 12 weeks with an average of(7.44±1.72)weeks. One patient was not healed due to comminuted fracture of fracture end and the separation was large, the blood supply to humeral head was insufficient for necrosis absorption. Postoperative Constant-Murley shoulder score at 3 months was 87.56±6.93; 15 patients got excellent results, 14 good, 2 fair and 1 poor. CONCLUSIONS: Limited external fixation with plastic paperboard for the treatment of senile proximal comminuted humeral fracture could ensure biomechanical stability of fracture, promote early recovery of shoulder joint function and shorten recovery time.

[Logistic regression analysis on the outcome predictive factors of ruptured lumbar disc herniation].

OBJECTIVE: To investigate the outcome predictive factors of ruptured lumbar disc herniation after conservative treatment. METHODS: From June 2009 to June 2016, 147 patients with ruptured lumbar intervertebral disc herniation were treated with conservative treatment in the orthopedics department of Suzhou Traditional Chinese Medicine Hospital for clinical efficacy and MRI follow-up. Multivariate Logistic regression analysis(Stepwise regression method)was used to analyze the relationship between the 11 categorical variables and absorptivity of protrusions: sex(X1), age(X2), course of disease(X3) , the rate of protrusion(X4), the Komori type(X5), the MSU type(X6), the Iwabuchi type(X7), the Pfirrmann grade(X8), the Modic change on adjacent vertebrae(X9), spinal canal morphology(X10), the Schizas types of cauda equina sedimentation sign(X11). RESULTS: A total of 64 cases of prominent reabsorption among all cases followed-up (absorption rate>=30%), accounting for 43.5%. The reabsorption of protrusions is more likely to occur in patients with a duration of less than 1 year(P=0.006), MSU type 3 (P=0.001), Iwabuchi type 1 or 5 (P=0.000), the Schizas type of cauda equina sedimentation sign A or B(P=0.004). Regression equation Y=-10.363+1.916X3+1.446X4-1.445X5+2.070X6+4.679X7+1.125X9+1.023X10+2.223X11. Such factors as age, gender, Pfirrmann classification and spinal canal morphology had no significant effect on reabsorption of protrusions. CONCLUSIONS: Ruptured lumbar disc herniation can be reabsorbed after nonoperative treatment. And the reabsorption of protrusions is more likely to occur in patients with a duration of less than 1 year, MSU type 3, Iwabuchi type 1 or 5, the Schizas type of cauda equina sedimentation sign A or B, which can be used as the key reference factors for predicting the outcome of the projections.

Incidence of Spontaneous Resorption of Lumbar Disc Herniation: A Meta-Analysis.

BACKGROUND: Lumbar disc herniation (LDH), a common disease, is often treated conservatively, frequently resulting in spontaneous resorption of the herniated disc. The incidence of this phenomenon, however, remains unknown. OBJECTIVE: To analyze the incidence of spontaneous resorption after conservative treatment of LDH using computed tomography and magnetic resonance imaging. STUDY DESIGN: Meta-analysis and systematic review of cohort studies. SETTING: The work was performed at The Suzhou Hospital of Traditional Chinese Medicine, Shanghai University of Traditional Chinese Medicine. METHODS: We initiated a search for the period from January 1990 to December 2015 using PubMed, Embase, and the Cochrane Library. Two independent reviewers examined the relevant reports. The references from these reports were also searched for additional trials using the criteria established in the PRISMA statement. RESULTS: Our results represent the pooled results from 11 cohort studies. The overall incidence of spontaneous resorption after LDH was 66.66% (95% CI 51% - 69%). The incidence in the United Kingdom was 82.94% (95% CI 63.77% - 102.11%). The incidence in Japan was 62.58% (95% CI 55.71% - 69.46%). LIMITATIONS: Our study was limited because there were few sources from which to extract data, either in abstracts or published studies. There were no randomized, controlled trials that met our criteria. CONCLUSIONS: The phenomenon of LDH reabsorption is well recognized. Because its overall incidence is now 66.66% according to our results, conservative treatment may become the first choice of treatment for LDH. More large-scale, double-blinded, randomized, controlled trials are necessary to study the phenomenon of spontaneous resorption of LDH.Key words: Lumbar, disc herniation, spontaneous resorption, conservative treatment, incidence, country, meta-analysis, systematic review, observational studies, study designs.

[Effects of serum enatninine Gumibao (Chinese character: see text) on the aroliferation and differentiation of osteoblast induced by dexamethasone].

OBJECTIVE: To investigate the effects of serum containing Gumibao (Chinese character: see text) on the proliferation and differentiation of osteoblast induced by dexamethasone. METHODS: Osteoblasts were extracted from skulls in newly born (within 24 hours) SD rats, and digested with collagenase. The first passage of cells were used for experiments. Cells were cultured in the medium containing different concentrations of dexamethasone (0, 10(-8), 10(-7), 10(-6), 10(-5) ,10(-4) mol/L). Alkaline phosphatase staining were carried out after 1 week and numbers of mineralized nodes with alizarin red staining were observed after 3 weeks. Accordingly, following the treatment of 10(-5) mol/L dexamethasone for 1 week, cells were cultured in the medium with serum containing Gumibao (Chinese character: see text). One week after Cumibao (Chinese character: see text) treatment, cells were stained with Alkaline phosphatase and collagen I and PCNA were examined by Western-blot. However, the observation of numbers of mineralized nodes with alizarin red stain required one more week. RESULTS: High concentration of dexamethasone could inhibit the expression of PCNA, collagen I, alkaline phosphatase and reduce the number of mineralized nodes of osteoblast, while serum containing Gumibao (Chinese character: see text) could reverse the inhibition. CONCLUSION: High concentration of dexamethasone could inhibit the proliferation and differentiation of osteoblastic cells, while serum containing Gumibao (Chinese character: see text) could reverse the inhibition.

Traditional Chinese medicine treatment for ruptured lumbar disc herniation: clinical observations in 102 cases.

OBJECTIVE: To explore the therapeutic effects of a traditional Chinese medicine (TCM) regimen on patients with ruptured lumbar disc herniation, including assessing its effects on prognosis and protrusion size. METHODS: From June 2008 to December 2011, 102 patients with ruptured lumbar disc herniation who chose conservative treatment with TCM as their first choice were followed up for 2 years to assess their final surgical rate, improvement according to Japanese Orthopaedic Association (JOA) scores, and to calculate the volume and rate of resorption of their protrusions by magnetic resonance imaging (MRI). RESULTS: (i) Eighty-three of the 102 patients (81.37%) experienced partial or complete relief; the remaining 19 (18.63%) eventually needed surgery. (ii) In the 83 patents who underwent conservative treatment, rates of excellent JOA scores at 3 months, 6 months, 1 year and 2 years were 79.52%, 81.93%, 81.93% and 83.13% respectively; differences between these and pretreatment scores are all statistically significant (P < 0.01). (iii) The volume of protrusion in the patients who chose conservative treatment decreased from 1433.89 ± 525.49 mm(3) (mean ± SD) to 1002.01 ± 592.95 mm(3), which is statistically significant (t = 6.854, P < 0.01). The average resorption rate was 27.25% ± 32.97%; in 20 patients (24.10%) the resorption rate was >50%. The remaining 63 patients had no obvious resorption; their excellent rate was 77.77%. The difference in rate of achieving an excellent outcome differed significantly between those who did and did not have resorption of their protrusions (P = 0.018). CONCLUSION: Conservative treatment with a TCM regimen is effective for ruptured lumbar disc herniation and can promote resorption of the protrusion; however, patients who develop specific indications for surgery during such treatment should undergo surgery in a timely manner.

Golden plaster for pain therapy in patients with knee osteoarthritis: study protocol for a multicenter randomized, double-blind, placebo-controlled trial.

BACKGROUND: Osteoarthritis is a relatively common musculoskeletal disorder that increases in prevalence with age. Worldwide, knee osteoarthritis is one of the leading causes of disability, particularly in the elderly. In numerous trials of agents for long-term pain therapy, no well-established and replicable results have been achieved. Complementary and alternative medical approaches have been employed for thousands of years to relieve knee osteoarthritis pain. Among herbal medicines, the golden plaster is the preferred and most commonlyused method in China to reduce pain in patients with knee osteoarthritis, as it causes few adverse effects. The purpose of this study will be to evaluate the efficacy and safety of golden plaster on pain in patients with knee osteoarthritis. METHODS/DESIGN: This study will be a multicenter randomized, double-blind, placebo-controlled trial. A total of 320 participants aged 45 to 79 years with knee osteoarthritis, whose scores on a visual analog scale (VAS) are more than 20 mm,will be randomly allocated into a treatment group and a control group. A golden plaster will be administered externally to participants in the treatment group for 2 weeks, while the control group will receive a placebo plaster externally for 2 weeks. Follow-up will be at regular intervals during a 4-week period with a VAS score for pain, quality of life, and complications. DISCUSSION: This study will be a methodologically sound randomized controlled trial to assess pain relief after the intervention of golden plaster, compared to a placebo intervention in patients with knee osteoarthritis.

CONCLUSION: The essential oil from fresh rhizome of Cyperus rotundus shows structure diversity and good analgesic effect.

[An experimental study on the influence of radix astragali on the ressorption of ruptured disc herniation].

OBJECTIVE: To investigate the possible mechanism of immune response in the resorption of the ruptured intervertebral disc herniation, and the possible mechanism of radix astragali on the resorption of the ruptured disc herniation. METHODS: Twenty-eight male SD (Sprague-dawley) rats were chosen. The rats were randomly divided into 4 groups: the control group, model group, the group treated with radix astragali injection and the group treated whit thymic peptide. The rats were killed and discs were harvested 10 days after treatment. Flow cytometry and HE staining were used for analysis of cells and tissue. RESULTS: Compared with the control group, the proportion of activated T cells (CD4+ and CD8+) and B cells were significantly higher in the two drug-treatment groups. CONCLUSION: Herniated nucleus pulposus attracts activated T and B cells and triggered an immune response. Radix astragali could strengthen the autoimmune response.
