Abstract
OBJECTIVE To observe the effect of wheat-grain moxibustion at "Dazhui" (GV 14) on the expressions of Beclin-1 and GRP78 in spinal dorsal horn in rats with cervical spondylotic radiculopathy (CSR), and to explore the possible analgesic mechanism of wheat-grain moxibustion for CSR. METHODS A total of 48 SD rats were randomly divided into a sham operation group, a model group, a wheat-grain moxibustion group and a wheat-grain moxibustion+3-MA group, 12 rats in each group. The CSR model was prepared by spinal cord insertion method. Three days after modeling, the rats in the model group were intraperitoneally injected with 1 mL of 0.9% sodium chloride solution; the rats in the wheat-grain moxibustion group were treated with wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time) on the basis of the model group; the rats in the wheat-grain moxibustion+3-MA group were intraperitoneally injected with 3-MA solution and wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time). The three groups were intervened for 7 days, once a day. The gait score and mechanical pain threshold were observed before treatment and 7 days into treatment; after the treatment, the expressions of mRNA and protein of Beclin-1 in spinal dorsal horn were detected by real-time fluorescence quantitative PCR and immunohistochemistry; the expression of GRP78 protein in spinal dorsal horn was detected by Western blot method; the autophagosomes and ultrastructure in spinal dorsal horn neurons were observed by electron microscope. RESULTS After the treatment, compared with the sham operation group, in the model group, the gait score was increased and the mechanical pain threshold was decreased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was increased (P<0.01). Compared with the model group and the wheat-grain moxibustion+3-MA group, in the wheat-grain moxibustion group, the gait score was decreased and mechanical pain threshold was increased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was decreased, and the expressions of mRNA and protein of Beclin-1 were increased (P<0.01). Under electron microscope, the ultrastructure of spinal dorsal horn neurons in the wheat-grain moxibustion group was not significantly damaged, and its structure was basically close to normal, and the number of autophagosomes was more than the other three groups. CONCLUSION Wheat-grain moxibustion at "Dazhui" (GV 14) has analgesic effect on CSR rats. The mechanism may be related to moderately up-regulate the expression of Beclin-1, enhance autophagy and reduce endoplasmic reticulum stress.

Abstract
BACKGROUND Direct moxibustion (DM) is reported to be useful for cervical spondylotic radiculopathy (CSR), but the analgesic mechanism remains unknown. Autophagy plays a protective role in neuronal apoptosis, Act A/Smads signaling pathway has been confirmed to be associated with the activation of autophagy. The study aimed to explore the effect of DM on autophagy in rats with CSR and the involvement of Act A/Smads signaling pathway. METHODS Rats were randomly divided into Sham, CSR, CSR + DM, CSR + DM + 3-MA (PI3K inhibitor), and CSR + DM + SB (Act A inhibitor) group. Three days after establishment of CSR model with a fish line inserted under the axilla of the nerve roots, DM at Dazhui (GV14) was performed six times once for seven consecutive days. Western blot and immunofluorescence staining were used to observe the expression of the neuronal autophagy molecule LC3II/I, Atg7, and Act A/Smads signaling molecule Act A, p-Smad2, and p-Smad3. Bcl-2/Bax mRNA expression was measured by real time PCR. RESULTS DM improved the pain threshold and motor function of CSR rats and promoted the expression of Act A, p-Smad2, p-Smad3, LC3II/I, and Atg7 in the entrapped-nerve root spinal dorsal horn. DM reduced the expression of Bax mRNA and decreased the number of apoptotic neurons. 3-MA and Act A inhibitor SB suppressed the expression of above-mentioned proteins and reduced the protective effect of DM on apoptotic neurons. CONCLUSION DM exerts analgesic effects by regulating the autophagy to reduce cell apoptosis and repair nerve injury, and this feature may be related to the Act A/Smads signaling pathway.

Abstract
OBJECTIVE To compare the clinical effect of acupuncture combined with wheat-grain moxibustion and oral sertraline hydrochloride dispersible tablets in the treatment of mild to moderate postpartum depression. METHODS Sixty patients with mild to moderate postpartum depression were randomly divided into an observation group and a control group, 30 cases in each group. Both groups were treated with psychotherapy. The control group was treated with oral sertraline hydrochloride dispersible tablets, 50 mg each time, once a day; the observation group was treated with acupuncture at Qihai (CV 6), Zusanli (ST 36), Xuehai (SP 10), Hegu (LI 4), Sanyinjiao (SP 6), Taixi (KI 3), etc. combined with wheat-grain moxibustion at Xinshu (BL 15), Pishu (BL 20), Ganshu (BL 18) and Shenshu (BL 23), once every other day, 3 times a week. Both groups were treated for 4 weeks as a course, with 2 consecutive courses of treatment. Before and after treatment and follow-up of 3 months after the end of treatment, the Hamilton depression scale (HAMD), Edinburgh postnatal depression scale (EPDS) and World Health Organization quality of life-BREF (WHOQOL-BREF) score of the two groups were compared, and the clinical effect was assessed. RESULTS After treatment and during follow-up, the HAMD and EPDS scores of the two groups were lower than before treatment (P<0.05), and the WHOQOL-BREF scores of the two groups were higher than before treatment (P<0.05). In the control group, the scores of HAMD and EPDS during follow-up were higher than after treatment (P<0.05), and the score of WHOQOL-BREF during follow-up was lower than after treatment (P<0.05). After treatment and during follow-up, the HAMD and EPDS scores of the observation group were lower than those of the control group (P<0.05), and the WHOQOL-BREF score of the observation group was higher than that of the control group (P<0.05). The total effective rate of the observation group was 93.3% (28/30), which was higher than 86.7% (26/30) of the control group (P<0.05). CONCLUSION Acupuncture combined with wheat-grain moxibustion can improve the depressive symptoms of patients with mild to moderate postpartum depression and improve their quality of life, and the clinical effect is more lasting and stable than oral sertraline hydrochloride dispersible tablets.

Abstract
Objective: To investigate the radiographic and clinical assessment for supracondylar humeral fractures resulted from sports in children. Methods: The medical records of 166 patients with displaced supracondylar humerus fractures treated in Shengjing Hospital of China Medical University from January 2015 to December 2015 were reviewed.The etiology of 56 of 166 cases was relevant to the sports.Medical records of 56 of 166 patients were reviewed, incluidng gender, the mean age of patient at the time of surgery, the mean duration of injury, radiographic assessment based on the anteroposterior (AP) and lateral radiographs of the elbow, neurologic injury, the Mayo Elbow Performance Score (MEPS) and the criteria of Flynn. Results: There were 34 boys (34 elbows, 60.7% (34/56)) and 22 girls (22 elbows, 39.3% (22/56)), and 32 patients in left elbow (57.1% (32/56)) and 24 patients in right elbow(42.9% (24/56)). The etiology included football in 16 patients (28.6% (16/56)), basketball in 10 patients (17.9% (10/56)), skating in 10 patients (17.9% (10/56)), skiing in 8 patients (14.3% (8/56)), roller skating in 5 patients (8.8% (5/56)), kick scooter in 3 patients (5.3% (3/56)), riding horse in 2 patients (3.6% (2/56)) and horizontal bar in 2 patients (3.6% (2/56)). The mean age of 56 patients at the time of surgery was 9.5 years ( range from 6 to 13 years). The mean duration of injury was 2.2 days (range from 4 hours to 35 days). The AP and lateral radiographs of the elbow of all 56 patients (56 elbows) were performed, and three dimensional computed tomography(CT) were performed in 23 patients (23 elbows). There were 54 patients in extension type(96.4% (54/56)) and 2 cases in flexion type (3.6% (2/56)) of supracondylar humeral fractures. There were 20 patients (35.7% (20/56)) of Gartland type Ⅱ and 34 patients (60.7% (34/56)) of Gartland type Ⅲ in 54 patients of extension-type. Two cases of flexion type were both Gartland type Ⅱ (3.6% (2/56)). 33 patients (58.9% (33/56)) had posteromedial displacement of the distal fragment, 21 patients (37.5% (21/56)) had posterolateral displacement of the distal fragment, and 2 patients (3.6% (2/56)) had anterolateral displacement of the distal fragment. Three dimensional CT showed the "-" shape and apposite "V" shape in the anterio edge of proximal fragments in 21 patients (91.3% (21/23)) and 2 patients (8.7% (2/23)), respectively.CT showed Gartland type Ⅲ in 5 patients those AP and lateral radiographs of the elbows were Gartland type Ⅱ.The neurologic deficit of radial nerve injury in 2 patients (3.6% (2/56)) resulted from displaced distal fragment.Closed reduction and percutaneous pinning were performed in all 56 patients.The pin configuration included two or three parallel lateral pins in 46 patients (82.1% (46/56)) and two or three divergent lateral pins in 10 patients (17.9% (10/56)). Of the 56 patients, 7 patients were lost to follow-up, leaving a follow-up rate of 87.5% (49/56). The mean length of follow-up was 9.6 months (range from 4 to 14 months). There were no cases of Volkmann's ischaemic contracture, or iatrogenic injury of nerve.There were 25 excellent (44.6% (25/56)), 19 good (33.9% (19/56)), 10 fair results (17.9% (10/56)) and 2 poor results (3.6% (2/56)); the rate of excellent and good outcome was 78.5% (44/56) according to the criteria of Flynn.There were 47 excellent (83.9% (47/56)), 4 good (7.1% (4/56)) and 4 fair results (7.1% (4/56)) and 1 poor result (1.9% (1/56)), and the rate of excellent and good outcome was 91.0% (51/56) according to the MEPS. Conclusions: Sports is the common reason of supracondylar humeral fracture requiring surgical treatment in children.CT is valuable for the diagnosis of supracondylar humeral fracture.Good functional results in the short-term follow-up can be found after closed reduction and percutaneous lateral-entry pinning.

Abstract
We report experimentally that room-temperature ferromagnetism of Co-doped ZnO is strongly correlated with structural defects, and that carriers involved in carrier-mediated exchange are by nature by-products of the creation of the defects. On the other hand, the carrier concentration has pronounced influences on the absorption edge in optical transmission spectra of epitaxial Co:ZnO films, in which both a blue-shift and a red-shift are observed. Furthermore, high-temperature annealing results in evolution of the local Co structure from Co(2+) replacing Zn(2+) to a Co(3)O(4)-based phase, which most likely accounts for the transition from ferromagnetism to paramagnetism in the Co:ZnO films.
