ObjectiveTo investigate the prevention and treatment of pneumonia in patients with acute cervical spinal cord injury (CSCI).MethodsData of 278 patients with acute traumatic CSCI admitted from 1988 to 2004 were analyzed retrospectively.Results Pneumonia was the major complication following acute CSCI and discovered by radiography during the first 3—33 days after injury. The all cases were nosocomial pneumonia and G- bacilli were main pathogens, particularly pseudomonas aeruginosa. The incidence of pneumonia of patients with score ≤6 according to the criteria of American Spinal Injury Association (ASIA) was significantly higher than those with ASIA score >6 (P<0.001).ConclusionThe high incidence of pneumonia in the CSCI is associated with the level and completeness of the injury. The G- bacilli causing nosocomial infection are main pathogens.

Objective: To unveil the efficacy of Shaolin internal qigong exercise in treating capsulitis of the shoulder (CS) and explore objective outcome measures by observing the changes in the surface electromyography (sEMG) signals of shoulder muscle groups after regular practice of Shaolin internal qigong exercise in CS patients. Methods: Sixty CS patients were randomized into two groups by the random number table method, with 30 cases in each group. Patients in the qigong group practiced Shaolin internal qigong exercise on a regular basis, while patients in the electroacupuncture (EA) group received EA treatment. Before and after treatment, the sEMG signals of six muscles, i.e. biceps brachii, triceps brachii, deltoid, pectoralis major, latissimus dorsi and trapezius muscles, of the affected side were recorded at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed during maximal isometric contraction, and the integrated electromyography (iEMG) of each muscle was calculated. Results: The total effective rate was 93.3％ in the qigong group, higher than 83.3％ in the EA group (P<0.05). Intra-group comparison showed that the iEMG of biceps brachii, triceps brachii, pectoralis major and deltoid muscles in the qigong group increased significantly after intervention at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed (all P<0.05), and the iEMG of trapezius and latissimus dorsi muscles decreased (both P<0.05); in the EA group, the iEMG of biceps brachii, pectoralis major and deltoid muscles increased significantly during contraction (all P<0.05), while the iEMG of triceps brachii, trapezius and latissimus dorsi muscles had no significant changes (all P>0.05). After intervention, there were significant differences in the iEMG of most of muscles between the two groups (all P<0.05), except for the iEMG of deltoid muscle at 45° of abduction of the shoulder joint during isometric contraction (P>0.05). Conclusion: Shaolin internal qigong exercise can effectively increase the motion intensity of the biceps brachii, triceps brachii, pectoralis major and deltoid muscles and reduce the compensation of the latissimus dorsi and trapezius muscles in CS patients; compared with EA, it produces a better result in improving the coordination and stability in shoulder joint movements.

[ ABSTRACT] AIM: To detect basic fibroblast growth factor ( bFGF ) expression in clinical common malignant tumor ( non-small-cell lung cancer,breast cancer, colon cancer and melanoma) , and to identify relationship between the expression and tumor clinicopathological characteristics.METHODS:Immunohistochemical SP method was used to detect the expression of bFGF at protein level in 208 cases of paraffin-embedded tissue of primary malignant tumor patients ( 68 cases of lung cancer, 80 cases of breast carcinoma, 41 cases of colon cancer and 19 cases of melanoma) .RESULTS:The bFGF protein expression levels were significantly higher in low differentiated non-small-cell lung cancer with lymph node metastasis, and were positively correlated with TNM.In addition, no significant influence of the bFGF protein expression on the patients with median survival period was observed.The protein expression of bFGF was higher in advanced breast cancer with lymph node metastasis and was commonly found in the middle/higher differentiated colon cancer with regional lymph node metastasis.Meanwhile, bFGF protein was highly expressed in advanced melanoma patients with lymph node metastasis.CONCLUSION:bFGF may participate in the process of occurrence and progression of malignant tumor.Ex-pression of bFGF protein may be an effective parameter for evaluating metastasis and prognosis of malignant tumor.

· AIM: To investigate the expression and the possible implication of CD40/CD40L costimulatory molecules in erythema nodosum of patients with Beh(c)et's disease.· METHODS: Sampling was done from erythema nodosum of 5 patients with Beh(c)et's disease and normal skin of 2 healthy individuals. Immunohistochemical staining was performed to examine the expression of CD4, CD8, CD19, CD68, HLA-DR,CD40 and CD40L molecules in the obtained tissues.· RESULTS: Approximately 90% of epidermic cells in erythema nodosum expressed CD40 molecule. In the dermis and subcutaneous tissue, a significantly increased number of CD4+Tcells, CD8+Tcells, CD19+cells, CD68+cells, HLA-DR+cells,CD40L+cells, and CD40+cells were observed in the erythema nodosum as compared with that in normal skin. Double staining showed that CD40L molecules were expressed on 45% of CD4+T cells. CD40 molecules were expressed on 100% CD68+ cells and 59.2% of HLA-DR+cells respectively.· CONCLUSION: A number of CD40/CD40L costimulatory molecules are upreguiated in the erythema nodosum of patients with Behcet's disease.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.
