Objective To compare the cervical intervertebral movements produced by posteroanterior cervical mobilization and posteroanterior cervical mobilization combined with cervical traction by using the radiographic measurement.Methods The study recruited 12 normal volunteers (6 men,6 women),aged 18 to 25 years (22.9±4.7 years),heighted (164± 7)cm and weighed (54.7 ± 7.6)kg.All the subjects were administered with posteroanterior cervical mobilization followed by posteroanterior cervical mobilization while having cervical traction,or vice versa,with an interval of 2 days in between.The X-ray films were collected before and after the treatment,using 4 static cervical lateral views.The axial displacement of posterior and anterior intervertebral separation (IVS),and the shear displacement of vertebral body as well as the rotation and displacement rate of the motion segments in the sagittal plane before and after the treatment were measured on the radiographic images and compared.Results It was shown that the posteroanterior cervical mobilization produced greater C2-C7 rotation range of motion in the sagittal plane,as compared to that by the posteroanterior mobilization while having cervical traction (P ＜ 0.05).The posteroanterior mobilization produced a significantly greater increase of anterior IVS of the C5 segment and the summation of C2-C7 posterior IVS than those by posteroanterior mobilization while having cervical traction (P ＜ 0.05).However,the posterior IVS and the posterior zygapophysial joints separation of C2-C7 produced by the posteroanterior mobilization during traction were more prominent (P ＜ 0.05).There was no statistical difference between anteroposterior displacements of the vertebral body produced by the two interventions.Comparing with the baseline,the posteroanterior mobilization caused posterior movement of the vertebral bodies of C5 to C2,while the posteroanterior cervical mobilization during traction produced posterior movement of C5 to C2 vertebral bodies and anterior movement of C6 body.Conclusion The cervical posteroanterior mobilization significantly increased the lordosis from C3 to C7,and reduced posterior IVS and zygapophysial joints separation.However,the posteroanterior mobilization during traction changed the intervertebral movements.

Objective To study the value of leptin,adiponeetin and interleukin (IL-1,IL-6,IL-8) in diagnosis,treatment,and prognosis of cerebral infarction.Method The levels of serum leptin ,adiponectin and IL-1,IL-6,IL-8 in acute cerebral infarction before and after treatment were determined with ELISA as well as in the healthy controls.The relationship between these indices and nerve function injury was studied.Results The levels of serum leptin and IL-1,IL-6,IL-8 in the patients increased significantly,but the controls didn't (P

The effect of amygdalin joint hydroxysafflor yellow A (HSYA) on the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and the possible mechanism were studied and explored. Chondrocytes were obtained from endplate of one-month SD rat intervertebral discs and cultured primary endplate chondrocytes. After identification, they were divided into normal group, induced group, amygdalin group, HSYA group and combined group. CCK-8 kit was adopted to detect the proliferation of the endplate chondrocytes. FCM was measured to detect the apoptosis. Real-time PCR method was adopted to observe the mRNA expression of Aggrecan, Col 2 alpha1, Col 10 alpha1, MMP-13 and the inflammatory cytokines IL-1beta. The protein expression of Col II, Col X was tested through immunofluorescence. Compared with the normal group, the proliferation of the endplate chondrocytes decreased while the apoptosis increased (P < 0.05). With down regulation of the mRNA expressions of Aggrecan, Col 2 alpha1 and up regulation of the mRNA expressions of Col 10 alpha1, MMP-13, IL-1beta (P < 0.05), the protein expression of Col II decreased while the protein expression of Col X increased. Compared with the induced group, amygdalin group, HSYA group, the combined group could inhibit the apoptosis and promote the proliferation (P < 0.05). They could increase the mRNA expressions of Aggrecan and Col 2 alpha1 while decrease the mRNA expressions of Col 10 alpha1, MMP-13 and IL-1beta (P < 0.05). They could also enhance the protein expression of Col II while reduce the protein expression of Col X. The effect of the combined group was significantly better than that of amygdalin and HSYA. Amygdalin joint HSYA could inhibit the degeneration of the endplate chondrocytes derived from intervertebral discs of rats induced by IL-1beta and better than the single use of amygdalin or HSYA.

CD127 is the interleukin7 receptor ?(IL7R?),it regulates the specific respond of T lymphocytes to IL7.CD127 plays an indispensable role in the development of thymocytes into T lymphocytes,the survival and homeostatic proliferation of memory T cells.There are only two phases of the life period of T cells that do not express CD127:immature CD4+8+double positive(DP)thymocytes and activated T cells.Recently,it was found that CD127 play an important role as the specific marker of memory T cells and regulator T cells.The role and mechanism of CD127 in the life period of T cells were discussed herein.

To prepare PLGA fiber scaffolds by electrospinning process and investigate the influence of preparation parameters on the structure of the scaffolds. With the compound of THF and DMF as the solvent, the PLGA fiber scaffolds with different surface morphology were fabricated via altering PLGA solution concentration, flowing rate and applied electric field strength. The morphology and diameter of the fibers were observed using a scanning electron microscope (SEM). The biocompatibility of cell-scaffold complex was also evaluated by seeding human dermal fibroblasts onto the PLGA fiber scaffolds, including cell adhesion and proliferation. The results show that the diameter of fibers and the bound of distributing increase with the increase in the concentration of PLGA solution. As the flowing rate increases, the diameter of fibers increases. However, with the increase in the applied electric field strength, no significant difference in the diameter of the fiber can be observed. Furthermore, both the increase in the concentration of PLGA solution and applied electric field strength in the volume range of current investigation can lead to the reduction in the beads formation within the scaffold. The results of in vitro cell culture on the PLGA scaffolds also confirm that the PLGA fiber can support the adhesion and proliferation of huaman dermal fibroblasts.

ObjectiveTo survey 0—6 years old disabled children in Guiyang.Methods4 999 children aged 0—6 years old chosen randomly from 9 145 children of 12 blocks were investigated with the disability sampling survey criteria of 1987.ResultsThe rate of disabled children in Guiyang was 1.58%, and was not significantly different compared with that of whole country (1.36%) and other three areas including Siping City (P>0.05),but significantly higher than that of other six districts including Heping district of Tianjin municipality (P<0.05). All kinds of disability found by this survey were separately intellectual disability (0.92%),comprehensive disability (0.28%),limb disability (0.24%),vision disability (0.10%),psychiatric disability (0.03%),and hearing disability (0.02%). Rates of intellectual and vision disabilities were significantly higher than that of whole country ( P>0.05).ConclusionSome diseases are directly relative to occurrence of disability. The poor income of the children family,lower education of his parents and not gotten preschool education were risk factors of disability. The institution based rehabilitation and community based rehabilitation are main rehabilitation forms to disabled children.

OBJECTIVETo analyze the efficiency of cervical lymph node metastasis dissection and postoperative morbidity after selective three-field lymph node dissection (3FLND) for thoracic esophageal squamous cell carcinoma, and explore the proper selection conditions.

METHODSAccording to the conditions as follows: systemic evaluation, tumor T staging, tumor location, cervical CT and ultrasonography and the number of lymph nodes metastases, 85 patients with thoracic esophageal squamous cell carcinoma were selected and received 3FLND.

RESULTSIn the same period 45.5% (85/187) of the patients received 3FLND selectively based on the conditions. The rate of the cervical lymph nodes metastasis was 40.0% (34/85). The rate of the cervical positive lymph nodes of the upper, middle and lower thoracic esophageal carcinomas with enlarged lymph nodes suggested by cervical CT and ultrasonography was 68.4% (13/19), 41.7% (20/48) and 16.7% (1/6), respectively. Twelve patients with upper thoracic esophageal carcinoma with enlarged lymph nodes unrevealed by cervical CT and ultrasonography showed no histopathological lymph node metastasis. In the same period 17.1% (32/187) of the patients were selectively not undergone three-field lymph node dissection. The cervical lymph node metastasis rates in patients with upper and middle mediastinal lymph node metastasis were 79.3% (23/29) and 58.6% (17/29), significantly higher than 8.9% (5/56) and 7.1% (4/56) in the patients without upper and middle mediastinal lymph node metastasis (P<0.05). There was no in-hospital mortality in the group. The incidence of pulmonary complications and over-all postoperative morbidity was 24.7% and 42.4%, respectively.

CONCLUSIONSSelective 3FLND based on certain conditions can reduce the risk of postoperative morbidity and improve the efficiency of metastatic cervical lymph node dissection in thoracic esophageal squamous cell carcinoma. The thoracic tracheoesophageal groove positve lymph node indicated by CT scans should be one of selective conditions for 3FLND. The upper thoracic esophageal carcinoma should selectively receive 3FLND. The selection standards should be more strict for the lower thoracic esophageal carcinoma.
