Biological Titer Determination of Traditional She Medicine-Gardeniae Radix / 中国药师

Objective: To study the antimicrobial effectiveness against traditional She medicine-Gardeniae Radix and determine the titer of Gardeniae Radix.Methods: The antibacterial activity of five standard strains(Escherichia coli , Staphylococcus aureus , Pseudomonas aeruginosa , Candida albicans and Aspergillus niger)was investigated.A method for the biological value evaluation of Gardeniae Radix was established by using a turbidity method, and compared with the content of chikusetsu saponin Ⅳa determined by HPLC.Results: The sensitivity of Gardeniae Radix to Staphylococcus aureus and Escherichia coli was high.The recovery of the turbidity method was within the range of 90%-110%, and the reliability limit rate was less than 5%.The content of chikusetsu saponin Ⅳa in Gardeniae Radix was not completely consistent with the result of the bioassay method.Conclusion: The bioassay method established in the experiment can be one of the methods for the quality evaluation of Gardeniae Radix.

Study of the level of adiponectin in obstructive sleep apnea-hypopnea syndrome patients / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the change of fasting serum adiponectin in obstructive sleep apnea-hypopnea syndrome (OSAHS) patients.@*METHOD@#Forty males with OSAHS and forty age-matched male normal controls were included in the study. Subjects in OSAHS group were divided into two sub-groups according to body mass index (BMI): obese OSAHS group (BMI > or =25, n=26) and non-obese group OSAHS (BMI <25, n=14). All subjects underwent an overnight sleep study. The serum adiponectin levels were measured by ELISA.@*RESULT@#(1) Except for BMI,compared with control subjects, levels of fasting adiponectin level were significantly lower in OSAHS subjects (P < 0.05). (2) In obese OSAHS sub-group, serum adiponectin level was negatively correlated with BMI and AHI. However, serum adiponectin level was positively correlated with the minimum oxygen saturation. There were similar correlations between serum adiponectin level and sleep parameters in non-obese OSAHS sub-group.@*CONCLUSION@#Despite age and BMI, fasting adiponectin level was significantly lower in OSAHS patients than that in control subjects. And fasting adiponectin level was correlated with BMI, AHI and the minimum oxygen saturation. OSAHS is one of the main reasons of the decreased adiponectin.

Survival analysis of 315 cases of laryngectomy / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigation the clinic long-term result and explore the prognostic factor of patients with laryngectomy.@*METHOD@#Three hundred and fifteen patients with laryngectomy were analysed. The survival rate and the cause of death were collected from this study.@*RESULT@#Five years later, 233 cases were still alive, 60 cases were dead, 22 cases failed to be followed-up. Overall 5-year survival rate was 73.97%, 5-year survival rate for patients of early stage was 82.69. Whereas, for patients of late stage was 62.64%. Five year survival rate for patients of supraglottic carcinoma, glottic carcinoma, subglottic carcinoma and transglottic carcinoma was respectively 73.76%, 82. 55%, 55.56%, 68.75%. Five year survival rate for patients with partial laryngectomy was 79.89%, whereas, for total laryngectomy was 1.03%. The cause of death were local recurrence and cervical glands metastasis.@*CONCLUSION@#Early diagnosis was the key points to both larynx preservation and survival rate. for improving survival rate, we should handle the indications strictly. remain sufficient security cutting edge and follow-up visit.
