Objective To observe the clinical effects of Bufei Yishen treatment on quality of life of patients with chronic obstructive pulmonary disease in stable period. Methods Sixty-four patients were randomly divided into two groups, the control group (32 cases) received Atrovent metered dose inhaling and Mucosolvan po. The treatment group (32 cases) received the fluid extract of Bufei Yishen besides the routine treatment. Both groups were treated for three months. The changes of scores of TCM syndrome and cardinal symptom, quality of life (QOL), lung function were observed before and after the treatment. Results The scores of TCM syndrome and cardinal symptom, quality of life of the treatment group were significantly higher than the control group (P0.05). Conclusion Bufei Yishen treatment has significantly effect on quality of life of patients with chronic obstructive pulmonary disease in stable period.

ObjectiveTo investigate the clinical characteristics,3-month outcome and predictive factors in the very elderly patients with ischemic stroke.MethodsA total of 305 acute ischemic patients aged 65 years and over were enrolled in the study.They were divided into two subgroups by age:80 years old and over(n =78),65-79 years old(n =227).The clinical outcome was assessed by the modified Rankin Scale (mRS) on (90 ± 7 ) days after stroke,and categorized as good ( scoring 0-2 ) or poor( scoring 3-6) outcome.Results Significantly lower BMI [ ( 23.62 ± 4.92 ) kg/m2 vs ( 25.08 ± 3.69 ) kg/m2,P =0.005],lower frequency of dyslipidemia(56.41％ vs 71.13％,P =0.006) and alcohol intake (0％ vs 6.61％,P =0.043 )were found in the very elderly group.The rates of poor functional outcome in the ≥ 80years group and the 65-79 years old group were 56.41％ (44/76) and 41.40％ (94/224) respectively,with a P value of 0.015.Multivariate logistic regression analysis showed that higher National Institute of Health stroke scale (NItISS) total score (OR 1.48,95％ CI 1.19-1.83 ) and lower albumin level (OR 0.73,95 ％ CI 0.55 -0.95 ) were associated with poor outcome in ≥ 80 year old,whereas higher NIHSS total score ( OR 1.38,95％ CI 1.24-1.53) and complications during hospital stay ( OR 2.58,95％ CI 1.07-6.19 ) were predictive factors in the 65-79 years old group.ConclusionOur study suggests that NIHSS scores,albumin level and complications during hospitalization are useful predictive factors for the short-term poor functional outcome in the patients of ≥65 years old and ≥80 years old patients have a worse prognosis.

OBJECTIVE: To set up a natural degeneration model of chondrocytes derived from endplate of intervertebral discs of rats in order to offer an appropriate carrier for the study on mechanism of intervertebral disc degeneration. METHODS: The method of enzyme digestion combined with natural subculture was used to set up the in vitro natural degeneration model of chondrocytes derived from the endplate of intervertebral disc of rats. The morphological appearances and microstructures of the chondrocytes of different generations were observed. The expression of collagen II in chondrocytes was detected by immunocytochemical method. RESULTS: The chondrocytes derived from the endplate of intervertebral disc expressed collagen II. After 13 days of culture, the chondrocytes of generation III showed that the ability of cell division descended, the nucleoli became unclear, the cells deformed obviously, fusiform shape with weak optical activity appeared, and the intercellular space was enlarged. There were vacuoles and lipid droplets in cytoplasm. The synthesis of collagen II, as well as the cell proliferation rate, descended notably. All results showed the natural degeneration process of the chondrocytes. CONCLUSION: The in vitro natural degeneration model of chondrocytes derived from endplate of intervertebral discs of rats was successfully established. This can offer the cytological basis for study on the mechanism of intervertebral disc degeneration.
