Influence of the dentin smear layer trait on the bond strength of the self-adhesive resin cements / 华西口腔医学杂志

OBJECTIVE@#This work aimed to evaluate the influence of smear layer on the bonding effectiveness and durability of the self-adhesive resin cements to dentin.@*METHODS@#A total of 48 fresh caries-free third molars with exposed dentin surface were divided into two groups. The dentin surfaces were treated using a standard grit diamond bur (group A) or further polished using a fine grit diamond bur (group B) and then bonded with either of the two self-adhesive resin cements, namely, Clearfil SA Cement (CSA, Kuraray) and Multilink Speed (MS, Ivoclar Vivadent). After 24 h or 2-year water storage, a microtensile bond strength test was performed.@*RESULTS@#In group A, the dentin surface was rough, the smear layer was thick, and the dentin tubule orifice detritus showed low embolism value. In group B, the dentin surface roughness decreased, the embolism proportion increased, and the smear layer became thin. The initial bonding strengths of CSA and MS in group A were significantly lower than those in group B (P0.05).@*CONCLUSIONS@#The properties of the smear layer and the types of self-adhesive resin cement used affected the bond strength and durability.

Post-stroke depression treated with acupuncture and moxibustion: an evaluation of therapeutic effect and safety / 中国针灸

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of acupuncture and moxibustion in the treatment of post-stroke depression (PSD) by regulating the liver and strengthening the root prescription.</p><p><b>METHODS</b>In light of the random controlled trial principle, 123 cases were randomized into an acupuncture-moxibustion group (42 cases), a medication group (40 cases) and an acupuncture + medication group (41 cases). In the acupuncture-moxibustion group, the therapy of regulating the liver and strengthening the root was applied. Acupuncture was given at Hegu (LI 4), Taichong (LR 3), Baihui (GV 20, Yintang (GV 29), etc. The granule moxibustion was applied at Zhongwan (CV 12), Xiawan (CV 10), Guanyuan (CV 4) and Qihai (CV 6). The treatment was given once a day and stopped in weekend. In the medication group, paroxetine hydrochloride tablets were prescribed for oral administration, 20 mg each day after breakfast. In the acupuncture + medication group, the therapies were adopted as the acupuncture-moxibustion group and the medication group. In the 2nd and 4th week of treatment, HAMD was used as the primary index and Barthel index as the secondary one for the efficacy assessment in the three groups respectively. The spleen and stomach syndrome scale of TCM was used for the assessment of TCM syndrome efficacy. Treatment emergent symptom scale (TESS) was applied for the safety assessment.</p><p><b>RESULTS</b>In the 4th week of treatment, the markedly effective rates were 69.0% (29/42), 65.0% (26/40) and 70.7% (29/41) in the acupuncture-moxibustion group, the medication group and the acupuncture + medication group respectively. The efficacies of anti-depression were similar in comparison among groups (P > 0.05). In the 2nd week of treatment, the improvement of HAMD score was significant in the acupuncture + medication group as compared with that before treatment and in comparison with the medication group (P < 0.05, P < 0.01). As for improving Barthel index, reducing the spleen and stomach symptom score of TCM and decreasing the score of TESS, the results in the acupuncture-moxibustion group and the acupuncture + medication group were superior to those in the medication group (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>The therapy of acupuncture and moxibustion with regulating the liver and strengthening the root achieves the definite efficacy of anti-depression and presents the quite high safety in treatment.</p>

Observation on relations between onset seasons of peripheral facial paralysis and therapeutic courses and effect of acupuncture / 中国针灸

<p><b>OBJECTIVE</b>To observe the influences of seasonal factors on peripheral facial paralysis by acupuncture.</p><p><b>METHODS</b>Four hundred cases of facial paralysis were divided into spring, summer, autumn and winter groups, 100 cases in each group. All these cases were treated by routine puncture. Fengchi (GB 20), Yifeng (TE 17), Qianzheng (Extra), Jiache (ST 6), and Dicang (ST 4), etc. were applied at affect side, once a day. 2 months observation was carried on to compare the clinical therapeutic effects and average courses. The facial symptoms, physical sign and functional activities were taken as observation indexes of therapeutic effect.</p><p><b>RESULTS</b>The effect rate was 78.0% (78/100) in spring group, 82.0% (82/100) in summer group, 89.0% (89/100) in autumn group and 92.0% (92/100) in winter group; the effect rate in summer or autumn group was superior to those in spring group and in summer group (all P < 0.05); the average course was (47.6 +/- 22.3) days in spring group, (43.7 +/- 18.4) days in summer group, (31.5 +/- 11.3) days in autumn group and (22.6 +/-9.2) days in winter group, indicating the significant differences between groups except that between spring and summer group (all P < 0.01). The cured and markedly effective rate was 80.1% (161/201) for wind cold type, 53.5% (61/114) for wind heat type, and 36.5% (31/85) for damp heat type, indicating that it of wind cold type was superior to that of wind heat type or damp heat type (P < 0.001, P < 0.05).</p><p><b>CONCLUSION</b>The syndrome distribution and courses of peripheral facial paralysis are different in different seasons, hence, the diseases should be treated according to attack time and syndromes.</p>

Observation on therapeutic effect of acupuncture at Xuanzhong (GB 39) combined with Chinese herbs pyrogenic dressing therapy for treatment of calcaneus spur / 中国针灸

<p><b>OBJECTIVE</b>To compare therapeutic effects of acupuncture at Xuanzhong (GB 39) combined with Chinese herbs pyrogenic dressing therapy and common acupuncture on calcaneus spur.</p><p><b>METHODS</b>A single-blind, randomized and controlled trial was adopted. Sixty-six cases were randomly divided into an observation group (n=34) and a common acupuncture group (n=32). The observation group was treated with acupuncture at Xuanzhong (GB 39) combined with Chinese herbs pyrogenic dressing therapy and the common acupuncture group with common acupuncture, Yanglingquan (GB 34), Kunlun (BL 60) etc. selected. The markedly effective rate and the changes of heel pain scores, heel swelling scores, heel burning sensation scores, and walking function scores were compared between the two groups before and after treatment.</p><p><b>RESULTS</b>The markedly effective rate of 64.7% (22/34) in the observation group was higher than 37.5% (12/32) in the common acupuncture group (P<0.05). After treatment, all the scores in the two groups were significantly improved as compared with before treatment (all P<0.05), and the observation group was better than the common acupuncture group (all P<0.05).</p><p><b>CONCLUSION</b>The therapeutic effect of acupuncture at Xuanzhong (GB 39) combined with Chinese herbs pyrogenic dressing therapy on calcaneus spur is superior to that of common acupuncture.</p>

<p><b>OBJECTIVE</b>To compare therapeutic effects of acupuncture at "cervical three points" combined with cake-separated moxibustion and routine acupuncture at Jiaji (EX-B 2) on cervical hyperosteogeny.</p><p><b>METHODS</b>Single blind, randomized and controlled methods were used and 91 cases were divided into an observation group of 46 cases and a control group of 45 cases. The observation group was treated by acupuncture at "cervical three points" combined with cake-separated moxibustion, i.e. acupuncture at Chonggu (EX), Dazhui (GV 14), Taodao (GV 13) and moxibustion at pain points with cake made by Rhizoma Atractylodis Macrocephalae and Radix Paeoniae Alba; the control group was treated with acupuncture at Jiaji (EX-B 2). Changes of sourness and pain of the neck, the shoulder and back, pressure pain and cervical activity scores were used for assessment of therapeutic effects.</p><p><b>RESULTS</b>The markedly cured rate of 76.1% in the observation group was better than 42.2% in the control group (P<0.05). After treatment, the scores of all the items were significantly improved in the two groups (all P<0.05), and the observation group in sourness and pain of the neck, the shoulder and back, and cervical activity were better than the control group (all P<0.05).</p><p><b>CONCLUSION</b>The therapeutic effect of acupuncture at "cervical three points" combined with cake-separated moxibustion on cervical hyperosteogeny is superior to routine acupuncture at Jiaji (EX-B 2).</p>
