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.展开更多

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.展开更多

Methods: A total of 130 nerve root type cervical spondylosis patients were randomly divided into acupuncture + traction + Qigong exercise (ATQE) group (n=59), acupuncture + Qigong exercise (AQE) group (n=40) and traction + Qigong exercise (TQE) group (n=31). Main acupoints used were Fengchi (GB 20) and cervical Jiaji (EX B 2) on the affected side. Results: After one month’s treatment, in ATQE, AQE and TQE groups, 43 (72.88%), 18 (45.00%) and 12 (45.16%) had remarkable amelioration, 14 (23.72%), 14 (35.00%) and 10 (32.26%) were effective, and 2 (3.39%), 8 (20.00%) and 7 (22.58%) had no apparent changes with the total effective rates being 96.61%, 80.00% and 77.41% respectively. The therapeutic effect of ATQE group was significantly superior to that of AQE and TQE groups (P<0.01).展开更多

Methods： Fifty-seven NT-CS patients were randomly divided into WCT group and Jiaji acupoint-acupuncture（JA） group according a random number table. WCT group（30 cases） was treated with WCT for 10 min, and JA group（27 cases） was treated with acupuncture for 10 min. The treatment efficacies were evaluated with a Visual Analogue Scale（VAS）. Blood perfusion at Dazhui（GV 14） and Jianjing（GB 21） acupoints（affected side） was observed with a laser speckle flowmetry, and its variations before and after treatment in both groups were compared as well. Results： In both groups, the VAS scores significantly decreased after the intervention（P〈0.01）, while the blood perfusion at the two acupoints significantly increased after intervention（P〈0.05）; however, the increasement magnitude caused by WCT was obvious compared with JA（P〈0.05）. Conclusion： WCT could improve analgesic effects in patients with NT-CS, which might be related to increasing local blood perfusion of acupunct points.展开更多

To explore the cutting reproduction technology of P. crassifolia and reveal its rooting mechanism, cuttings of P. crassifolia with different cutting types （softwood, hardwood and root）, positions （top, upper, middle and bottom） and ages （7, 10, 15, 20, 25 year-old） were cultivated in a field experiment. One- year old softwood and hardwood cuttings were collected from 7-, 10-, 15-, 20-, and 25 year-old healthy ortets to analyze the changes from endogenous hormones and organic nutrients. Results indicate that the softwood cut- tings （0.5-1.0 cm in diameter） from upper branches of 15 year-old ortets shows better growth performance by improving rooting indexes, including a significant increasein rooting rate and a decrease in basal rot rate. Concomi- tantly, increasing rooting quantity and root length also increased. It is noteworthy that the high rooting rate of P. crassifolia cuttings due to its ability to accumulate high concentrations of indole-3-acetic acid （IAA） and total carbon （TC） rather than abscisic acid （ABA） and total nitrogen （TN）. The rooting rate was mainly regulated by the IAA/ABA and TC/TN ratio. In summary, our results suggest that the softwood cuttings （0.5-1.0 cm in diameter） from upper branches of 15 year-old P. crassifolia can be considered as an effective strategy to improve cutting rooting rate, and the IAA/ABA and TC/TN ratio was one of the main factors limiting the cutting rooting rate of P. crassifolia.展开更多

As one of the complications of T2 DM, diabetic neuropathic pain(DNP) stubbornly and chronically affects the health and life of human beings. In the pain field, dorsal root ganglion(DRG) is generally considered as the first stage of the sensory pathway where the hyperexcitability of injured neurons is associated with different kinds of peripheral neuropathic pains. The abnormal electrophysiology is mainly due to the changed properties of voltage-gated sodium channels(VGSCs) and the increased sodium currents(INa). Curcumin is an active ingredient extracted from turmeric and has been demonstrated to ameliorate T2 DM and its various complications including DNP effectively. The present study demonstrates that the INa of small-sized DRG neurons are significantly increased with the abnormal electrophysiological characteristics of VGSCs in type 2 diabetic neuropathic pain rats. And these abnormalities can be ameliorated efficaciously by a period of treatment with curcumin.展开更多

The weakening of γ-aminobutyric acid-mediated presynaptic inhibition may be an important cause of neuropathic pain. γ-aminobutyric acid-mediated presynaptic inhibition is related to the current strength of γ-aminobutyric acid A receptor activation. In view of this, the whole-cell patch-clamp technique was used here to record the change in muscimol activated current of dorsal root ganglion neurons in a chronic constriction injury model. Results found that damage in rat dorsal root ganglion neurons following application of muscimol caused concentration-dependent activation of current, and compared with the sham group, its current strength and γ-aminobutyric acid A receptor protein expression decreased. Immunofluorescence revealed that γ-aminobutyric acid type A receptor α2 subunit protein expression decreased and was most obvious at 12 and 15 days after modeling. Our experimental findings confirmed that the y-aminobutyric acid type A receptor α2 subunit in the chronic constriction injury model rat dorsal root ganglion was downregulated, which may be one of the reasons for the reduction of injury in dorsal root ganglion neurons following muscimol-activated currents.展开更多

A. Chev. provenances originating from Kenya （Taveta）, Malawi （Bolero） and Ghana （Bolgatanga）; representing east, south and west Africa, respectively. Bulked seeds from three provenances were grown in two soil types （clay and sand） at the World Agroforestry Centre nursery, Nairobi. Seedlings grown in clay soil had high shoot growth and shoot to root ratios but shorter root length, lower number of nodules and specific root length compared to seedlings in sand soil. Shoot to root ratios reduced with time and this was more pronounced in sand soil. Overall, the Bolero and Taveta provenances had higher growth than the Bolgatanga provenance. This was probably because plants grown in nutrient-rich clay soil invest more in shoot growth as compared to root growth. Longer root growth in sand soil shows a better adaptive mechanism that increases competitive ability and survival in nutrient-poor systems. Variations observed among the seedling variables such us shoot and root growth could be used for early selection for reforestation and agroforestry in predominantly clay and sand soil areas.展开更多
