ObjectiveTo assess the efficacy and results of cervical double door laminoplasty for the treatment of cervical spinal cord injury without radiographic spinal fracture and dislocation.Methods24 patients (all men) with cervical spinal cord injury without radiographic spinal fracture and dislocation were treated with operation of cervical double door laminoplasty. The follow up period ranged from 3 months to 21 months. ASIA scores of motion and sensation before and after operation were compared.Results After surgical treatment, ASIA scores of motion and sensation of patients were improved from 35.2±7.1 and 72.4±13.1 to 59.3±6.8 and 122.2±15.2 respectively and having a significant difference compared with that before operation (P<0.01).Conclusion Cervical double door laminoplasty, which is characterized by thorough decompression of spinal cord and preserving the posterior supporting tissue as much as possible to maintain the stabilization of cervical spine after operation, is an ideal optional method for cervical spinal cord injury without radiographic spinal fracture and dislocation.

Antioxidant activity of bronchial epithelial cells (BECs) plays an essential role in preventing the airway epithelium integrity from damage in structure and function. Integrin expressed by BECs is the receptor of extracellular matrix such as fibronectin (Fn), and it is involved in modulation of proliferation, differentiation and metabolism of the cells. In order to test the hypothesis that integrin-ligand binding reaction supports the ability of cells to withstand oxidant attack, the present study evaluated the antioxidant activity of primary cultured rabbit BECs treated with fibronectin or its sequence Arg-Gly-Asp (RGD peptide), by determining changes in the activity of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) and in the level of glutathione (GSH). The results are as follows: (1) Fn (10 μg/ml) increased significantly the activity unit of GSH-Px (P<0.05, n=5), which was inhibited by calmodulin-inhibitor W7 　(10－5 mol/L) (P<0.05). Both Fn (5～20 μg/ml) and RGD (15～60 μg/ml) showed a dose-dependent upregulatory effect (respectively r=0.93 and r=0.73). (2) Treatment with Fn increased SOD activity (P<0.01,　n=7), which was abolished by W7 　(P<0.01). (3) Catalase activity was also stimulated by Fn (P<0.05, n=6) and reversed by W7 　(P<0.01). (4) A dose-dependent increase of GSH level was observed in both Fn (r=0.82) and RGD treatment (r=0.84). The data suggest that the binding of integrin with extracellular matrix can upregulate activity of antioxidant enzymes, and increase the content of GSH and improve the ability of BECs to resist oxidant injury.

To analyze retrospectively Mr. Xie Xiliang's medical records accumulated in 30 years on direct moxibustion for treating hepatitis B, in which 86 cases were included. Before accepting direct moxibustion, 80.23% of the cases had been treated by conventional Chinese and western medicine, but no satisfactory therapeutic effects were obtained. Direct moxibustion was applied for 7-9 cones at each point selected. Point selection was related to ages. Usually, only a few points were used, and Ganshu (BL 18) and Pishu (BL 20) were used as main points. Shenzhu (GV 12) was added for children, and Zusanli (ST 36) added for adults. The improvement rate in clinical symptoms and physical signs were 100%. In the cases with hepatauxe, splenauxe, liver cirrhosis, and abdominal dropsy diagnozed by the B-ultrasonic examination, the improvement was obvious. Of the total, the rates turning to be negative in HBsAg, HBeAg and HBcAb were 28.85%, 38.46%, and 36.54%, respectively. It took some 10 days to 1 month to begin to show improvement in physical signs and hepetic functions, and about 3-6 months for their restoration. For the five items tested in type B hepatitis, it took 5 months to 1 year, even several years, to show their improvement. It is indicated that direct moxibustion is definitely effective in treating type B hepatitis. It is easy to handle and worth popularizing.

Objective To study the risk factors of hyperthyroid heart diseases(HHD) by analyzing clinical features of patients in order to provide a scientific basis for prevention and treatment of HHD. Methods Nine hundred and eighty two cases were selected as objective from in-patient data of Thyroid Disease Treatment Centre of Shandong Province. The cases were divided into hyperthyroidism group and HHD group. The variables of etiology,sex, age, duration of disease, TSH, FT3, FT4 and TRAb were analyzed by comparative analysis. The risk factors were analyzed by logistic regression. Results The prevalence of hyperthyroidism complicated hyperthyroid heart disease was 7.7%(76/982), age, duration of diseases, FT3, TRAb in the HHD group were [(51.4 ± 11.5), (6.3 ±2.1) years, 21.6 pmol/L, 71.6 U/L], in hyperthyroidism group were [(37.9 ± 9.8), (2.6 ± 1.3) years, 14.9pmol/L, 49.6 U/L]. The differences were statistically significant(u = 9.93,15.23, T = 44954,48792.5, P ＜ 0.05)between the two groups. The factors of the older, higher FT3 and TRAb, longer duration, Graves disease (OR =1.751,1.470,1.483,1.445,1.234) increased the risk of HHD. Conclusions Graves disease, longer duration, old age, higher FT3 and TRAb are the risk factors of HHD. Timely prevention and control of risk factors is necessary to reduce the incidence of HHD.

To explore the role of regulatory peptides in the secretion of bronchial epithelial cells (BECs), we observed the effects of four peptides, i.e.vasoactive intestinal peptide (VIP), epidermal growth factor (EGF), endothelin-1 (ET-1), and calcitonin gene-related peptide (CGRP), on the secretion of ILs from unstimulated or O3-stressed BECs. The results of the experiments showed that VIP exerted an inhibitory effect on the secretion of IL-1 and IL-8 from unstimulated and O3-stressed BECs, VIP also decreased the secretion of IL-5 from O3-stressed BECs; EGF promoted secretion of IL-1 and IL-8 from unstimulated BECs, but decreased the secretion of ILs from O3-stressed BECs; ET-1 and CGRP enhanced the secretion of IL-1, IL-5, and IL-8 from unstimlated BECs, CGRP also increased the secretion of ILs from O3-stressed BECs. The results obtained demonstrate that intrapulmonary regulatory peptides modulate the secretion of ILs from BECs, and may play an important part in transduction of inflammatory signals.
