A new photochemical method was employed to cause regional cerebral throm-bosis in the rats by intravenous injection of the rose bengal (1mg/100g body weight)and focal illumination (with a filtered xenon lamp, ?560nm and △?60nm) of the intackskull surface. The regional cerebral blood flow (rCBF), stroke volume (SV), cardiac out-put(CO), heart rate(HR) and the regional blood flow of heart, liver, spleen, kidney andadrenal were used as indexes. The effects of cerebral hemodynamic alterations on cardiacfunction during photochemical reaction were discussed. The results showed that rCBF, SV,CO decreased markedly as compated with the contralateral (P

Waste printed circuit boards(W-PCBs) were multiple smashed and separated, then passed through a 60-mesh screen, treated with hydrochloric acid (2 mol/L), ultrapure water and dehydrated with acetone successively.The filter residue and filter paper were filled into the extraction pool, or inserted into Soxhlet Extraction tube parceled with new filter paper.After addition of 5 μL of internal standard substance, the filter residue above was respectively extracted by Soxhlet Extraction (SE) method or Accelerated Solvent Extraction (ASE) method, cleaned with multi-layer silica gel column and activated-charcoal column to obtained the dioxins samples.The samples were analyzed by isotope dilution high resolution gas chromatography-high resolution mass spectrometry (HRGC-HRMS).The effects of SE and ASE method and number of chlorines atoms on recovery of 15 kinds of 13C-2,3,7,8 PCDD/Fs were investigated, and the accuracy and precision of the two extraction methods were compared.The results show that, the recovery of 15 kinds of 13C-2,3,7,8 PCDD/Fs using ASE method is 54.3%-113.0%, and that of SE is 28.3%-77.7%, and the Toxic Equivalent Quangtity (TEQ) in W-PCBs is 0.075 ng/kg (TEQ) and 0.266 ng/kg (TEQ) using ASE and SE method respectively.Under the premise that accuracy and precision meet with the international standard, ASE is simple, rapid, solvent-free and accurate.

Objective:To investigate the effect of restraint stress on T, B lymphocyte transformation rate and phagocytic function of peritoneal macrophage.Method:Cells were extracted from the abdominal cavity of mice with S180 tumor and then were injected subcutaneously in the right oxter in 0.2 ml/mouse. Some of the mice were bound at the same time. There were four groups in all, they were normal control, tumor mice without restrain, restrained mice without tumor, and mice with both tumor cell injection and restrain. All mice were killed after 10 days, T and B lymphocyte transformation rates of spleen were examined, the phagocytic function of peritoneal macrophage was also tested. The weights of tumors were also recorded.Result:Compared with tumor mice without restrain, the mice with both tumor injection and restrain had lower T, B lymphocyte transformation rates and lower phagocytic function of peritoneal macrophage. The weight of tumor in the study group was also higher than that of tumor mice without restrain.Conclusion:Restraint stress aggravates the depression of the immune function of mice with S180 tumor and promotes the growth of the tumor.

Objective To observe the effect of acupuncture at lumbar Jiaji (EX-B 2) points plus botulinum toxin injection on the seated function of patients with spastic cerebral palsy.Method Sixty patients aged 1-4 years old with spastic cerebral palsy were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by acupuncture at lumbar Jiaji (EX-B 2) points plus botulinum toxin injection, while the control group was by conventional acupuncture plus botulinum toxin injection. After 3 treatment courses, the seated function zone (zone B) of Gross Motor Function Measure (GMFM) was used for evaluation, and the clinical efficacies were compared.Result Respectively after 1, 2, and 3 treatment courses, the total effective rates were 46.7%, 73.3% and 83.3% in the treatment group, versus 33.3%, 46.7% and 60.0%. There were significant differences in comparing the total effective rate between the two groups after 2 and 3 courses (P<0.05). After the first treatment course, the seated function score of GMFM was significantly changed in both groups (P<0.01). After the second course, the seated function score was significantly different from that after the first course in both groups (P<0.01). After the third course, the seated function score was significantly different from that after the second course in both groups (P<0.01). There was a significant between-group difference in comparing the changes of the seated function score during the second treatment course (P<0.01). There was a significant between-group difference in comparing the changes of the seated function score during the second treatment course (P<0.05). Conclusion Acupuncture at lumbar Jiaji (EX-B 2) points plus botulinum toxin injection can produce a more significant efficacy in improving the seated function of patients with spastic cerebral palsy.

Objective To investigate the clinical significance of antiendothelial cell antibodies (AECA) in systemic vasculitis. Method With Human umbilical vein endothelial cell (HUVEC) as substrate cell, sera from 129 systemic vasculitis patients [including 59 Behcet′s disease(BD), 28 Takayasu arteritis (TA), 20 Wegener′s granulomatosis (WG), 8 polyarteritis nodosa (PAN), 9 microscopic polyangiitis (MPA), 5 Churg-Strauss syndrome (CSS)] were screened for the presence of AECA by ELISA. Sera from SLE, RA and healthy donors were examined as controls. The association of AECA to clinical disease activity was analyzed. Result The prevalence of AECA by HUVEC cell-ELISA was 59% in systemic vasculitis [48% in BD,79% in TA, 65% in WG, 63% in PAN, 44% in MPA, 80% in CSS], 46% in SLE, 4% in RA, and 2.4% in control group. Compared with patients with RA and control group, AECA were more frequently found in patients with systemic vasculitis and SLE (P

Objective:To observe the clinical effect of acupuncture combined with low-frequency electric stimulation on scissor gait in children with spastic cerebral palsy. Methods:A total of 60 spastic cerebral palsy kids were allocated into two groups by random number table, 30 in each group. Cases in the control group were treated with physical exercise therapy, massage and hydrotherapy. Based on the therapies given to the control group, cases in the observation group were supplemented with acupuncture combined with low-frequency electric stimulation. Selected points included Zusanli (ST 36), Sanyinjiao (SP 6), Yanglingquan (GB 34), Jiexi (ST 41), Chengshan (BL 57), Naoqing [Extra, locates at 2 cun directly above Jiexi (ST 41)] and Genping (Extra, locates at the midpoint of the line connecting medial and lateral malleolus). The treatment was done once every other day and 10 d made up a treatment course. The low-frequency electric stimulation was applied to anterior tibia, 6 times a week and 20 times made up a treatment course. Cases were treated for a total of 3 courses and there was a 15-20 d interval between two courses. The low limb functions were assessed before and after treatment using the modified Ashworth scale (MAS) and composite spasticity scale (CSS). In addition, the ankle dorsiflexion angles were measured before and after treatment. Results:After treatment, the ankle dorsiflexion angles and CSS scores in the observation group were better than those in the control group, showing statistical significances (P<0.05); the effective rate in the observation group calculated by MAS and ankle dorsiflexion angle were both higher than that in the control group, showing a statistical significance (P<0.05). Conclusion:Rehabilitation training combined with acupuncture and low-frequency electric stimulation can achieve better effect than rehabilitation training alone in improving scissor gait in kids with spastic cerebral palsy.

BACKGROUND:Low back pain in patients with hip osteoarthritis can be relieved to some extent after total hip arthroplasty, indicating the changes in limb line of force have obvious effects on low back pain. OBJECTIVE:To review and analysis the pathological base and biomechanics mechanism of hip-spine syndrome. METHODS: We retrieved PubMed database and China National Knowledge Infrastructure for related articles published from January 1976 to March 2015. The key words were “low back pain, hip-spine syndrome, hip osteoarthritis, total hip replacement, biomechanics, balance parameters” in English and Chinese, respectively. Repeated studies and unrelated articles were excluded. RESULTS AND CONCLUSION:A total of 145 articles were retrieved, and finaly 62 articles were enroled in result analysis. In the pathophysiology, tumor necrosis factor-α, interleukin-1β and matrix metaloproteinases play a significant role in the occurrence and development of hip-spine syndrome. As for the biological biomechanics, the spine-pelvic-lower limb balance compensatory process can be the main mechanical mechanism of hip-spine syndrome, and the balance parameters can provide a basis for the diagnosis, treatment and postoperative evaluation of hip-spine syndrome.
