Prone-positioned upside-done arch exercise, a kind of lumbodorsal muscles training, curbs the progression of lumbar disc bulge

Objective： To study the effects of prone-positioned upside-done arch exercise, a kind of lumbodorsal muscles training originated from Yoga, on curbing the progression of lumbar disc bulge. Methods： A total of 120 out-patients, diagnosed with lumbar disc bulge by CT and/or MRI, were randomly divided into the observation group and the control group, with 60 patients in each group. Patients in the observation group received the prone-positioned upside-done arch exercise combined with traction and acupuncture for two months and followed with a two-year treatment with prone-positioned upside-done arch exercise while the patients in the control group only received traction and acupuncture for two months. After two years, patients in both groups were investigated for the visual analogue score, MR image and straight leg raise tests. Results： Compared to the control group, prone-positioned upside-done arch exercise combined with traction and acupuncture showed significant decrease in patients’ visual analogue score, bulge size and the positive ratio of straight leg raise test （P = 0.001, P = 0.001 and P = 0.02 respectively）, suggesting the inhibitory effect on the progression of lumber disc bulge. Conclusion： Prone-positioned upside-done arch has the potentials to protect patients with lumbar disc bulge from nerve root compression syndrome.

Acute Toxicity of Formalin to the Red-tide Dinoflagellate Prorocentrum minimum Schiller(Protozoa,Mastigophora)

The acute toxic levels of formalin to a marine red-tide dinoflagellate Prorocentrum minimum Schiller (Mastigophora, Dinoflagellida) were determined by linear regression analysis. The data obtained revealed that there is a close regression relationship between logarithmic concentrations of formalin and mortality probit scales of the organism when exposure times are 1, 2, 6, 12, 24h. The median lethal concentrations (LC50 values) obtained from correlation analysis for these exposure times (with 95% confidence intervals), were 11.83, 6.76, 4.37, 4.27 and 3.98mgL-1, respectively. A toxicity curve was obtained to connect the exposure time and LC50 value from the correlation between them. The results indicated that P. minimum could be killed or fixed by formalin in the concentration range of 4-12mgL-1 within 1-24h.

Assessment of Pricing Efficiency and Levels of Concentration in Cashew Nuts Market in South Western Nigeria

Cashew nuts market in south western Nigeria is characterized by price fluctuations through space and time. This may be linked with the large number of market intermediaries who act between the primary producers and the markets. The sample for the study comprised 250 cashew nuts marketers who were randomly selected from the five south westem states of Nigeria. About 76 % of the cashew nuts marketers had up to secondary school education and 86% of them had 15-year marketing experience and below. Pricing efficiency of the marketers was highest in Ogun state with average efficiency level of85.1% and least for Oyo state （68.9%）. In all, 720 tonnes were transacted in the region with 206 marketers handling maximum of 2 kg per month per individual. Gini-coefficient estimate of 82.3% implied that there was a concentrated market for the cashew nuts. To further increase the pricing efficiency of the commodity it is necessary to reduce the costs incurred on various physical aspects in marketing system. Corporate organizations, government agencies and co-operative societies should assist the cashew nuts marketers in the provision of credit facilities so as to ensure a higher level of pricing efficiency, stable market prices and reduced level of concentration of the marketers.

Clinical observation of tendon-regulating manipulation plus core stability training for non-specific low back pain

Objective： To evaluate the clinical efficacy of tendon-regulating manipulation plus kinesiotherapy in treating low back pain. Methods： Sixty patients were randomized into a treatment group and a control group by using the random number table, 30 cases in each group. The treatment group was intervened by tendon-regulating manipulation plus kinesiotherapy, while the control group was by the tendon-regulating manipulation alone. The lumbar lordosis was measured by X-ray （side view）, the pain was evaluated by analgesy meter, the lumbar range of motion was by using goniometer, and the function was judged by Oswestry disability index （ODI） before and after treatment, and the therapeutic efficacy was also observed. Results： After treatment, the pain level was significantly reduced, lumbar lordosis was significantly increased, the lumbar range of motion was markedly improved, and the ODI score significantly dropped （all P^O.05） in both groups; the improvement of each item in the treatment group was more significant than that in the control group （all P〈O.05）. The total effective rate was 90.0% in the treatment group versus 63.3% in the control group, and the difference was statistically significant （P〈0.05）. Conclusion＂ In the treatment of low back pain, tendon-regulating manipulation plus kinesiotherapy can mitigate topical pain, improve the motion of low back, enhance the quality of life, and produce a more significant therapeutic efficacy compared to tendon-regulating manipulation alone.

Clinical observation of sinew-regulating bone-setting manipulations plus exercise therapy for chronic non-specific low back pain

Objective:To evaluate the clinical efficacy of sinew-regulating bone-setting manipulations plus exercise therapy in treating chronic non-specific low back pain(CNLBP).Methods:A total of 65 CNLBP patients were divided into two groups by the random number table method.Thirty-three cases in the treatment group were intervened by sinew-regulating bone-setting manipulations plus exercise therapy;32 cases in the control group were intervened by medium-frequency electrotherapy plus exercise therapy.Before and after treatment,visual analog scale(VAS),dynamic and static muscle endurance of low back,median frequency(MF)of surface electromyography(sEMG)and Oswestry disability index(ODI)were used to evaluate the low back function.The therapeutic efficacy was estimated after treatment.Results:The two groups each had 2 dropouts during the study.The total effective rate was 90.3%in the treatment group versus 66.7%in the control group,and the between-group difference was statistically significant(P<0.05).After treatment,the VAS score,dynamic and static muscle endurance of low back,MF of sEMG and ODI score all changed significantly in both groups(all P<0.05);all the items in the treatment group were significantly different from those in the control group(all P<0.05).Conclusion:Sinew-regulating bone-setting manipulations plus exercise therapy can effectively release pain in CNLBP patients,increase muscle endurance of the low back and improve the quality of life,and its therapeutic efficacy is more significant than that of medium-frequency electrotherapy plus exercise therapy.

Effect of nano-hydroxyapatite/collagen composite and bone morphogenetic protein-2 on lumbar intertransverse fusion in rabbits

Objective: To investigate the effect of nano hydroxyapatite/collagen (nHA/collagen) composite as a graft extender and enhancer when combined with recombinant human bone morphogenetic protein 2 (rhBMP 2) on lumbar intertransverse fusion in rabbits. Methods: Sixty four adult female New Zealand white rabbits, aged 1 year and weighing 3.5 4.5 kg, underwent similar posterolateral intertransverse process arthrodesis and were randomly divided into 4 groups based on different grafts: autogenous cancellous bone alone (ACB group), nHA/collagen alone (HAC group), half autogenous cancellous bone and half nHA/collagen (ACB+HAC group) and nHA/collagen combined with rhBMP 2 (HAC+BMP group). The fusion masses were analyzed by manual palpation, radiography, biomechanical testing and histological examination. Results: Fusion was observed in 4 cases in the 6th week and in 5 cases in the 10th week after surgery in ACB group. No case showed fusion in HAC group. In ACB+HAC group, there was fusion in 3 cases in the 6th week and in 4 cases in the 10th week after surgery. In HAC+BMP group, fusion in 1 case was found in the 4th week, in 5 cases in the 6th week and in 6 cases in the 10th week after surgery. It suggested that ACB, ACB+HAC and HAC+BMP groups showed similar fusion ratio and mechanical strength in the 6th and 10th week after surgery. According to the microstructure analysis of the samples, nHA/collagen had no negative effect when implanted together with ilium autograft. In HAC+BMP group, new bone like tissue was observed in the 2nd week postoperatively, and nearly all of the implanted composites were replaced by mature bone matrix and new bones in 10th week postoperatively. Conclusions: The nHA/collagen, especially combined with rhBMP 2, is a promising bone substitute, for it has quick biodegradation, fine bone bending ability, and high osteoconductivity on posterolateral spinal fusion in rabbits.

Observation on the therapeutic efficacy of Tuina plus“three-bridge”exercise for non-specific low back pain

Objective To investigate the efficacy of Tuina(Chinese therapeutic massage)plus“three-bridge”exercise for non-specific low back pain(NSLBP).Methods A total of 80 patients with NSLBP were randomly divided into a control group and an observation group according to the random number table method,with 40 cases in each group.The two groups received Tuina treatment,and the observation group received an additional“three-bridge”exercise.The treatment lasted 4 weeks,and a follow-up evaluation was carried out 6 months after treatment.The visual analog scale(VAS),Oswestry disability index(ODI),and the Japanese Orthopaedic Association(JOA)scores for low back pain were used to evaluate patients’conditions before treatment,after 4-week treatment,and at the 6-month follow-up.Results The total effective rate was 92.5%and 85.0%in the observation group,respectively,after 4-week treatment and at the 6-month follow-up,significantly different from the control group(P<0.05).After 4-week treatment and at the 6-month follow-up,the VAS,ODI,and JOA scores of the two groups were improved compared with those before treatment(P<0.05),and all the indicators in the observation group were significantly better than those in the control group(P<0.05).At the 6-month follow-up,the VAS,ODI,and JOA scores in the two groups were improved compared with those before treatment(P<0.05).Conclusion Tuina plus“three-bridge”exercise can effectively alleviate pain,improve function,and have relatively sound long-term effects in treating patients with NSLBP.
