Objective To compare the vibrating perception threshold (VPT) between normal subjects and subjects with cervical spondylosis of nerve root type, and to observe the clinical efficacy of acupoint injection at Quyuan (SI13) in releasing pain in cervical spondylosis of nerve root type.Method Sixty-three patients with cervical spondylosis of nerve root type were recruited and randomized into a treatment group of 35 cases and a control group of 28 cases. The treatment group received acupoint injection at Quyuan, and the control group received acupoint injection at Jiaji (EX-B2) points. The short-form McGill Pain Questionnaire (MPQ) was adopted. From the questionnaire, the Pain Rating Index (PRI), sensory (S), affective (A), and total (T) pain rating indexes, Visual Analogue Scale (VAS), and Present Pain Index (PPI) were used to comprehensively evaluate the pain improvement and to quantify the therapeutic efficacy, and the VPT was also considered. The Clinical Assessment Scale for Cervical Spondylosis (CASCS) by West China Rehabilitation Center was also used to analyze the result in the treatment group.Result After the intervention, the MPQ and VAS scores in the treatment group were significantly lower than those in the control group (P<0.05). The total effective rate of the treatment group was significantly higher than that of the control group (P<0.05). Meanwhile, the VPT was improved after the treatment.Conclusion Acupoint injection at Quyuan can produce a more significant efficacy than at Jiaji (EX-B2) in treating cervical spondylosis of nerve root type.

Transforming growth factor-β is an important cytokine with various bioactivities, including embryonic development, wound healing, chemotaxis and cell cycle regulation. Epithelial-mesenchymal transition (EMT) is the main pathway of tumor cell to obtain the ability of invasion and metastasis. The TGF-β is the key factor known to induce EMT in cancer cells and plays an important role in the process. In recent years, some progress has been obtained. Some TGF-β inhibitors have approved in the market or in clinical trials. TGF-β inhibitors can play an important role on the treatment of tumors, glaucoma, liver and kidney fibrosis disease and scar repair. Novel TGF-β inhibitors reported in recent years were reviewed in this article.

A molecular template synthetic polymer highly selective for norfloxacinum was prepared by a molecular imprinting technique. The selective binding characteristics of the template polymer was evaluated by Scatchard analysis. The multiple-sites binding model was used to calculate the maximum numher of binding sites and the dissociation constant. The results showed that the template polymer using methacrylic acid (MAA) as functional monomer could form two kinds of binding sites. The dissociation constants were estimated to be Kd1 = 2.9 × 10-5mol/L and Kd2 = 3.2 × 10-3 mol/L. The selective binding experiment for substrates indicated that the polymer gave much higher affinity and selectivity for norfloxacin than for acid pipemidic and cefalexin. It is possible to be a good adsorption and binding material in the selective enrichment and determination of trace norfloxacin in complex biosamples.

BACKGROUND: Autologous bone graft was always applied to repair bony cavity defect produced by benign bone tumor.OBJECTIVE: Taking autogenous bone graft for repairing bony cavity defect caused by bone tumor or tumor-like pathological change as control standard, to observe transplantation of deproteined bovine cancellous bone combined with autogenous red marrow in occluding the residual cavity and the density of newly formed bone.DESIGN: A randomized grouping design, controlled observation SETTING: Department of Orthopaedics, the 175 Hospital of Chinese PLA PARTICIPANTS:We recruited 175 cases of bony cavity defect who received treatment in the Department of Orthopaedics, the 175 Hospital of Chinese PLA from July 1993 to July 1998. They were randomly assigned into two groups: experimental group and control group. There were 63 cases treated in the experimental group. The average disease-suffering time was (6.2±2.1) months and bone defect was (136±30) mm3. There were 62 cases treated in the control group. The average disease-suffering time was (6.1±2.3)months, and bone defect was (133±37) mm3.METHODS: Deproteined bovine cancellous bone combined with autogenous red marrow was transplanted in the experimental group and autologous bone graft was applied in the control group. We curetted tumor completely, cauterized the wound with alcohol of 0.95 volume fraction, then curetted the area of cauterization to make it bled. Bone graft was applied.The quantity of implanted bone should be abundant, and disposed compactly. The X-ray films of the first week after operation were used as a standard for density of new bone growth. X-ray films were taken at the 3rd,6th and 8th months postoperatively, and the X-ray films of the eighth months after operation were used as a standard.MAIN OUTCOME MEASURES: To compare the bone union in two groups with a standard of residual cavity occluding and density of bone growth.RESULTS: All patients were followed up for an average of 20 months.One case was lost six months after operation. And two cases were lost eighteen months after operation respectively in the experimental group and control group. After 8 months of operation, residual cavities of bone defect of 44 cases in experimental group and 46 cases in control group were disappeared. Palingenetic bone fused with left bone organization. Its density was the same as or higher than normal bone organization. Residual cavities of 12 cases in experimental group and 10 cases in control group were disappeared basically. The density of palingenetic bone was approximate to normal bone organization. To compare with autologous bone graft, deproteined bovine cancellous bone and an autogenous red marrow had an identical effect for repairing bony cavity defect.CONCLUSION: Bony cavity defect produced by benign bone tumor is often repaired by bone transplantation. To explore the substitutable grafting materials of autogenous bone in this study, a composite material composed of deproteined bovine cancellous bone and an autogenous red marrow (DBCAM) is applied to repair the bony cavity defect.

12 strains of H2-producing bacteria were isolated and purified from anaerobic sludge, aerobic sludge and river bottom sludge by Hungate method. A new species of high efficient hydrogen production bacterium Enterococcus sp. LG1 (registration number: EU258743 ) was studied deeply. It was showed that the Enterococcus sp. LG1 was an anaerobic and Gram-negative bacterium. Sequence analysis of this type of clones showed that it was affiliated with the genus Enterococcus and it was not reported yet in other paper at present. Meanwhile, batch tests of anaerobic fermentative hydrogen production by Enterococcus sp. LG1 were investigated by using sterilization pretreated sludge as substrate. The changes of soluble COD, protein, carbohydrate and pH value during hydrogen fermentation were monitored. It was found that only hydrogen and carbon dioxide were produced by this strain and no methane was detected during fermentation. The maximal hydrogen yield was 36.48 mL/g TCOD and the hydrogen concentration in the gas phase was 73.5%. The Enterococcus sp. LG1 was a butyrate fermentation bacteria analyzed by metabolites.
