Objective To investigate the effect of corpectomy decompression by subtotal vertebrectomy and fusion of adjacent segmental artificial disc replacement through anterior intervertenral spance (Hybrid Surgery) in the anteriorcervical spondylotic myelopathy treatment . Methods Hybrid Surgery were operated on 18 patients who suffered from anterior cervi?cal spondylotic myelopathy . Follow up of 1-50 months. Patient’s conditions were assessed according to the Japanese Associ?ation for Department of orthopedics assessment score (JOA score) before and after operation. Effects of Hybrid operation were assessed by the improvement of JOA score, Odom’s follow-up grade and cervical mobility . Results The JOA scores of all 18 operated patients were improved from 10.6 ± 1.7 before operation to 13.5 ± 2.4 after operation. And the difference is statistically significant (t=1.314, P < 0.05). Among all the operated patients, 16 were cured and 2 were effective. As to Odom’s follow up grades, 6 cases were excellent, 11 cases were good and 1 case was acceptable. The postoperative move?ment range of cervical spine (40.1° ± 8.4°) show no statistically difference compared with that in preoperation (42.6° ± 11.9°) (t=0.68, P > 0.05). Conclusion Hybrid Surgery of anterior cervical decompression and fusion can both improve the nerve function and preserve cervical mobility.

Background Researches showed that multifocal electroretinogram (mfERG) is able to assess the retinal function in the eyes with acute Vogt-Koyanagi-Harada ( VKH ) syndrome. But the mfERG characteristics of convalescence stage of VKH are still below clear. Objective Present study was to compare and follow up the variation process of visual acuity and mfERG in acute and recovery stages of VKH syndrome. Methods This was a clinic-based retrospective study. Visual acuity, mfERG and fundus fluorescence angiography ( FFA ) were recorded from 35 eyes of 18 acute VKH cases. The period of follow-up in recovery stage lasted about 18 months with the repetitive recording results for 4 times. Results In this study, the visual acuity range in acute stage VKH was 0. 01 to 1.0, and 91.4% (32/35 eyes) was below 0.6. Compared with normal control group, the visual acuity was significantly decreased (P＜0.01). The response densities (amplitudes) of N1 ,P1 waves of the first-order kernel were significantly lowed in all the 6 rings,and the implicit times of 1-4 rings of both waves were significantly prolonged in acute VKH eyes(P＜0. 05). The abnormalities of retinal function showed a regional difference at the posterior pole retina with the dominant change in the first ring,showing a cutting off78% in the P1 amplitude. The abnormal degree of mfERG was more serious as the the increase of retinal eccentricity. In 2 months of convalescence after glucocorticosteroids therapy,the range of visual acuity were 0. 1-1.2 ,and the amplitudes of N1, P1 of 1-2 rings were greatly elevated in comparison with acute on-set (P＜0. 05 ). However, there was still a remarkable difference in the amplitudes of from 1 through 6 rings,comparing with normal. The response density of P1 wave from whole recording region was only 44% of normal. Though the visual acuity was stable during the follow-up duration, a decreasing tendency in N1 and P1 amplitudes were seen. The implicit times of both wave shortened only in 1-3 rings in recovery stages of VKH (P＜0.05). Conclusion VKH syndrome cause serious damage of posterior retinal function.Macular region is the site with greater retinal functional lesion and restore before and after medication. This hardly recovery of retinal function can last over one and half year,even satisfied visual acuity is stable after proper treatment.

OBJECTIVETo compare clinical effects of spinal leveraging manipulation and medicine for the treatment of degenerative scoliosis in pain and function.

METHODSFrom July 2010 to June 2013, 38 patients with degenerative scoliosis were randomly divided into spinal leveraging manipulation group and medicine group by coin tossing. In manipulation group, there were 9 males and 11 females aged from 58 to 74 years old with an average of (66.63±7.73), the courses of diseases ranged from 3 to 8 months with an average of (5.65±2.58), spinal leveraging manipulation(following meridian to straighten tendon,relieving spasm, osteopathy and massage, clearing and activating the channels and collaterals) were performed for 30 min, once a day, 4 days for a period treatment, totally 9 courses. In medicine group, there were 8 males and 10 females aged from 57 to 70 years old with an average of (63.51±6.61) the courses of diseases ranged from 3 to 5 months with an average of (4.82±1.43), celecoxib with eperisone hydrochloride were orally taken, 4 days for a period treatment, totally 9 courses. VAS score, Cobb angle and ODI score were measured.

RESULTSAfter treatment, VAS score in manipulation group was (5.38±0.99), (6.36±1.31) in medicine group,and had significant meaning (t=2.618, P<0.05); there was significant differences in Cobb angle between manipulation group (16.51±4.89)° and medicine group (19.85±5.03) °(t=2.074,P<0.05); and had obviously meaning in ODI score between manipulation group (20.20±2.93) and medicine group (26.01±3.11) (t=5.592, P<0.05).

CONCLUSIONSpinal leveraging manipulation for degenerative scoliosis could regulate muscle balance on both side of spine, correct coronal imbalances in spine, recover normal sequence of spine, reduce and remove opperssion and stimulation of nerve root, relieve pain in leg and waist and further improve quality of life.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.

METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.

RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).

CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.
