Objective To explore the clinical features of systemic onset of juvenile idiopathic arthritis (SoJIA) with atlantoaxial subluxation as the initial manifestation. Methods The clinical data from one SoJIA patient with atlantoaxial subluxation as the initial manifestation were retrospectively analyzed. Results A 9-year-old boy presented the head and neck movement disorder as the ifrst symptom, developed fever on the third day, then rapidly progressed on 23rd day, with a sharp decline in red blood cell, platelet, and hemoglobin, blood coagulation dysfunction, and a large number of bilateral pulmonary exudation. Ultrasonography showed excess lfuid in abdomen, chest, and pericardium. According to the 2001 version of the revised International College of Rheumatology standard, the diagnosis of SoJIA combined macrophage activation syndrome was conifrmed. Then treated with hemoperfusion, ifltration, and methylprednisolone combined with cyclosporine A, the disease was in remission. Conclusion For children with spontaneous atlantoaxial subluxation accompanied by the systemic symptoms, with no obvious skeletal deformity or acute inlfammation etc., should be alerted to the consideration of systemic juvenile idiopathic arthritis.

OBJECTIVETo establish a disease-syndrome conjugated animal model, the mini-swine coronary heart disease (CHD) model of phlegm-stasis cementation syndrome type, by high fat diet feeding and coronary artery balloon injury.

METHODSMini-swine were randomly divided into the control group and the model group, 6 in each group. They were fed with common forage and high fat forage respectively for 10 weeks and the coronary left anterior descending branch in the model group was injured by balloon intervention technique after 2-week feeding to establish CHD model. The model establishment and its physiopathological indices were evaluated by examinations on body mass index (BMI), blood levels of lipid, high-sensitivity C-reactive protein (hs-CRP), body surface electrocardiograph (BS-ECG), coronary angiography and pathological indices.

RESULTSBMI, total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), hs-CRP, sigma-ST and N-ST indicated by BS-ECG in the model group were all higher than those in the control group respectively (P < 0.05 or P < 0.01). Coronary angiography showed coronary lumen narrowed with apparent lumen loss, showing a significant difference as compared with the control group (P < 0.01). In EVG staining, the diameters of lumen in the model group was obviously narrow with intima proliferation, also significantly different to those in the control group (P < 0.01).

CONCLUSIONDisease-syndrome combined model for coronary heart disease of phlegm-stasis cementation syndrome type in mini-swine could be established by high fat diet feeding with coronary arterial injury.

OBJECTIVETo investigate the early clinical effects and radiological outcome of dynamic cervical implant (DCI) internal fixation in treating cervical spondylosis, and evaluate its safety and efficiency.

METHODSFrom June 2009 to December 2011, 19 patients with cervical spondylosis correspond to the indication of DCI internal fixation in the study, including 5 cases of cervical spondylotic myelopathy and 14 cases of cervical spondylotic radiculopathy. There were 8 males and 11 females, aged from 35 to 54 years with a mean of 43.2 years. Pathological segments included C3,4 in 1 case, C4,5 in 6, C5,6 in 6, C6,7 in 4, C3,4 and C5,6, C6,7 in 2. All patients were treated with anterior discectomy and decompression and DCI internal fixation, meanwhile, 2 cases of them with anterior cervical corpectomy and fusion plate fixation. Clinical evaluation included Modified Japanese orthopedics association (mJOA), neck disability index (NDI), visual analogue scale (VAS) score and patient satisfaction index (PSI) at pre-operation and final follow-up. Radiographic evaluation included flexion/extension lateral view at operative level and adjacent segment. The adjacent level degeneration was analyzed according to Miyazaki classification on MRI images.

RESULTSAll patients were followed up from 12 to 42 months with an average of 19.8 months. Preoperative mJOA score was 13.6±1.1 and at final follow-up was 16.3±1.2 with improvement rate of 85.0%. Preoperative VAS,NDI was 6.6± 1.4, 17.1±7.4 and at final follow-up was 1.4±0.8, 6.1±3.9, respectively; there was statistical significance in all above-mentioned results between preoperative and final follow-up (P<0.05). Preoperative ROM at operation level was (7.6±1.9)° and final follow-up was (7.8+2.1)°; preoperative ROM at C2-C7 was (38.6±7.2)° and final follow-up was (39.9±6.4)°; there was no statistical significance in all above-mentioned results between preoperative and final follow-up (P>0.05). Preoperative DHI at operation level was (6.3±1.1) mm and final follow-up was (7.1±0.8) mm, there was statistical significance in DHI between preoperative and final follow-up (P<0.05). No heterotopic ossification was found. All patients followed up MRI, degeneration of 3 segments aggravated 1 degree in 38 adjacent segments, without clinical symptom.

CONCLUSIONTreatment of cervical spondylosis with dynamic cervical implant can got satisfactory outcome in early follow-up. Activity of operative segment obtain reservation in some degree. The incidence of adjacent segment degeneration is lower and no adjacent segment disease occur. Nevertheless a longer follow-up time should be needed to assess the long term functionality of the DCI and the influence on adjacent levels.

There have been very few studies on the effect of Gualou Xiebai Banxia decoction combined with Xuefu Zhuyu decoction in inhibiting apoptosis in myocardial ischemial injury caused by coronary heart disease. In this experiment, Gualou Xiebai Banxia decoction combined with-Xuefu Zhuyu decoction were used to intervene the miniature swine phlegm and blood stasis type coronary heart disease model, in order to observe the effect of the combined prescription on the myocardial apoptosis and the expressions of Bcl-2, Bax, Caspase-3, Caspase-9 in the model. Totally 15 Chinese experimental miniature swine were adopted and randomly divided into the control group, the model group and the phlegm and stasis-treating group. The model group and the stasis-treating group were fed with high fat diets for two weeks, intervened with the coronary artery injury and then given drugs and high fat diets for eight weeks. The control group was fed with ordinary diets for 10 weeks, without the coronary artery injury. After the experiment, myocardia at the juncture of infracted areas were collected and made into formalin-fixed paraffin sections. The TDT-mediate dUTP nick end labeling (TUNEL) assay was used to detect the myocardial apoptosis. The immunohistochemistry (IHC) technique was applied to detect Bcl-2, Bax, Caspase-3, Caspase-9 levels in myocardial tissues. According to the findings, the apoptosis indexes (AI) for the control group, the model group and the phlegm and stasis-treating group were 0.92%, 27.68%, 17.28%, respectively. The AI of the phlegm and stasis-treating group was significantly lower than that of the model group (P < 0.01). Compared with the model group, the phlegm and stasis-treating group showed significantly higher Bcl-2 protein expression (P < 0.01) and lower Bax, Caspase-3 and Caspase-9 protein expressions (P < 0.01). In conclusion, Gualou Xiebai Banxia decoction combined with Xuefu Zhuyu decoction have a significant protective effect against the myocardial apoptosis in miniature swine phlegm and blood stasis type coronary heart disease model.
