Objective To Observe the effects of treating primary trigeminal neuralgia with modified Shaoyao-Gancao decoction and carbamazepine. Methods 76 patients with primary trigeminal neuralgia were randomly divided into a treatment group and a control group, 38 patients in each. The treatment group was treated with modified Shaoyao-Gancao decoction and carbamazepine; and the control group was treated with carbamazepine only. Clinical curative effect, pain improvements and adverse reactions were observed after the treatment and 6 week follow-up. Results The total effective rate was 89.3%and 75.5%in the treatment group and the control group respectively, the difference was statistically significant(P=0.043). The onset frequency, duration, degree of pain were all improved in both groups after the treatment and 6 week follow-up[treatment group after the treatment is (0.54±0.78), (2.15±1.73), (1.58±1.26), 6 week follow-up is (0.24±0.63), (1.36±1.03),0.86±1.95);control group after the treatment is (1.98±1.68), (3.96±1.49), (3.02±1.45), 6 week follow-up is (1.06±1.78), (1.97±1.69), (2.13±1.54), P<0.05],and the treatment group was better than the control group(P=0.040 and 0.039 respectively). Conclusion Modified Shaoyao-Gancao decoction combined carbamazepine has good clinical curative effect in treating primary trigeminal neuralgia.

Objective To analyze the clinical effects of arthroscopic en masse repair with footprint ending shift using double-row suture-bridge technique for delaminated rotator cuff tears under tension.Methods A total of 58 patients with delaminated rotator cuff tears under tension from August 2013 to August 2016 who underwent arthroscopic en masse repair using doublerow suture-bridge technique were retrospectively analyzed.There were 33 males and 25 females with a mean age of 53.0±7.8 years (range 39-74) with 24 patients left side involved and 34 right side.They were divided into 2 groups to receive en masse repair either footprint ending shift or on the footprint.There were 28 patients with footprint ending shift and 30 patients on the footprint.Clinical effects were evaluated by University of California Los Angeles (UCLA) score,American Shoulder and Elbow Surgeons (ASES) score,visual analogue scale (VAS),Constant-Murley score and shoulder range of motion at preoperatively and postoperatively.Results The average follow-up duration was 23.2±0.8 months (range 21-24).The two groups were compatible with no significant difference in age,gender,tear size,follow-up duration,preoperative function and range of motion of the shoulder joint (P＞0.05).At the last follow up,the UCLA,ASES,VAS,Constant-Murley scores and shoulder range of motion in the group footprint ending shift were respectively 32.4±2.5,12.8±0.9,1.0±1.1,93.4±5.6,158.3°±9.3°,58.9°±5.0° with significantly differences compared with preoperative scores (P ＜ 0.05).The postoperative value in the group on footprint were respectively 31.6±2.9,12.8±0.9,0.7 ± 1.2,91.3±7.1,156.1°± 10.7°,59.6°±4.6° with significantly differences compared with the preoperative scores (P ＜ 0.05).There were no significant difference between the two groups (P ＞ 0.05).The operation duration in the group footprint ending shift was 100.9±6.0 min,while that in the group on footprint was 106.6±6.1 min.There was significantly difference in the operation duration between two groups (t=-3.600,P=0.001).Conclusion Arthroscopic en masse repair using double-row suture-bridge technique can successfully treat delaminated rotator cuff tears under tension.Compared with arthroscopic en masse repair on footprint using double-row suture-bridge technique,the footprint ending shift is easier and time saving without significant difference in function of the shoulder joint and the range of motion in repair of delaminated rotator cuff tear under tension.

Objective To evaluate the clinical efficacy of arthroscopic bursal layer-only double-row suture-bridge repair for delaminated rotator cuff tear which is difficult to reposit in comparison with separate double-layer repair and whole-layer repair.Methods From May 2013 through June 2016,82 patients with delaminated rotator cuff tear difficult to reposit were treated at Department of Joint Surgery,The Affiliate Hospital to Chengde Medical University.They were 47 males and 35 females with a mean age of 53.0 ± 7.9 years.They were divided into 3 groups according to their surgical procedures.In group A,28 cases were treated by arthroscopic whole-layer double-row suture-bridge procedure;in group B,29 cases were treated by arthroscopic separate double-layer double-row suture-bridge procedure;in group C,25 cases were treated by arthroscopic bursal layer-only double-row suture-bridge procedure.The 3 groups were compared in terms of University of California Los Angeles (UCLA) score,American Shoulder and Elbow Surgeons (ASES) score,visual analogue scale (VAS),Constant shoulder score,range of motion of shoulder joint and rotator cuff retear preoperatively and postoperatively.Results The patients in the 3 groups were comparable because their preoperative general data showed no significant significances (P ＞ 0.05).The operation time for groups A,B and C was respectively 105.5 ±5.6 min,117.4 ±6.9 min and 88.0 ±4.2 min,showing significant differences between the 3 groups (P ＜ 0.05).The 82 patients were followed up for 21 to 24 months (average,23.3 months).At 24 months postoperatively,UCLA,ASES,VAS,Constant score,shoulder anteflexion and lateral extorsion were respectively 32.4 ± 2.5,12.8 ± 0.9,1.0 ± 1.1,93.4 ± 5.6,158.3° ± 9.3°and 58.9°±5.0°in group A,32.2±2.5,12.9±1.0,0.9±1.0,92.8±6.0,156.4°±9.5°and 59.3°± 5.6° in groups B,and32.4±2.4,12.9±0.9,0.7±0.9,94.3±5.2,156.0°±9.5°and57.6°°5.4°in group C,showing no significant differences between the 3 groups (P ＞ 0.05).The occurrence of rotator cuff retear in groups A,B and C were respectively 17.9％ (5/28),13.8％ (4/29) and 12.0％ (3/25),showing no significant differences between the 3 groups (P ＞ 0.05).Conclusions In repair of delaminated rotator cuff tear difficult to reposit,although the arthroscopic bursal layer-only double-row suture-bridge repair is similar to conventional arthroscopic whole-layer double-row suture-bridge repair and arthroscopic separate double-layer double-row suture-bridge repair in functional recovery and range of motion of the shoulder and incidence of rotator cuff retear,it can reduce obviously operation time and make the operation easier.

Objective:To explore with healthy adults any effect on postural control of transcranial direct current stimulation (tDCS) applied over the left dorsolateral prefrontal cortex (L-DLPFC) and the primary motor cortex (M1).Methods:Eighteen healthy adults received 3 tDCS stimulation protocols sequentially applied to either the left dorsolateral prefrontal cortex alone, the left dorsolateral prefrontal cortex and the bilateral primary motor cortex simultaneously or sham stimulation, respectively. Each intervention protocol lasted for 20 minutes with a total current intensity of less than 4mA, with a 7-day interval between the each stimulation protocol. Single-task and dual-task walking and balance tests were administered before and after each stimulation protocol, followed by statistical analysis.Results:The results of the single-task gait function testing showed that the change in step width before and after single-target tDCS stimulation was (-0.511±1.072)cm, significantly better than with sham stimulation. In the dual-task gait function tests the change in step width after single-target tDCS stimulation was (-0.511±1.072)cm, significantly better than in the other two groups.Conclusions:Stimulating only the dorsolateral prefrontal cortex can effectively regulate cognitive-motor postural control. Multi-target tDCS offers no particular advantage.
