RESUMEN
OBJECTIVE:To study the stability of Fuke zhidai capsule at accelerated testing and room temperature. METHODS:HPLC was conducted to determine the content of berberine hydrochloride in the preparation:the column was Diamonsil C18 with mobile phase of B methanol-0.7% triethylamine(pH adjusted to 3 by phosphate)(50:50,V/V)at a flow rate of 1 ml/min;detec-tion wavelength was 265 nm,with a column temperature at 45 ℃,and the injection volume was 5 μl;its moisture,disintegration time,accelerated stability and long-term stability were studied according to the 2015 edition of Chinese Pharmacopoeia. RE-SULTS:The linear range of berberine hydrochloride was 0.0217-0.1736 mg/ml(r=0.9999);RSDs of precision,stability and re-producibility tests were lower than 2%;recovery was 97.24%-101.73%(RSD=1.72%,n=6). CONCLUSIONS:The moisture,dis-integration time,accelerated stability and long-term stability were all in line with the quality standards.
RESUMEN
OBJECTIVE@#To explore the effection of the pulmonary function of patients of chronic rhinosinusitis (CRS) with asthma which treated with endoscopic sinus surgery (ESS) based comprehensive treatment.@*METHOD@#There were 50 cases of chronic rhinosinusitis with asthma whom met the study criteria. 35 cases enrolled in the tri al group, which treated with endoscopic sinus surgery, and routine perioperative tratment. Another 15 cases as control group which underwent conservative treatment. Both groups underwent the rule treatment of asthma. The main monitoring indexes, which included visual analogue scale (VAS) score, endoscopic Lund-Kennedy score, control of asthma symptoms, the pulmonary function which involved forced expiratory volume in first second (FEV1), forced vital capacity (FVC), the ratio of forced expiratory volume in first second and forced vital capacity (FEV1/FVC) and peak expiratory flow (PEF), were measured in the patients of each groups before surgery, follow-up for 1 year and 3-year.@*RESULT@#Our study found that the VAS score of CRS with asthma was significantly negatively correlated with FEV1 and PEF (P < 0.05), endoscopic Lund-Kennedy score was significantly negatively correlated with PEF (P < 0.05); After the trial group underwent ESS based comprehensive treatment, the improvement of VAS score and endoscopic Lund-Kennedy score of postoperative compared with preoperative and the same period in the control group were significantly (P < 0.05). The difference of the postoperative asthma control rate of trial group after 1 year and after 3 years, respectively, compared with the same period control group were statistically significant (P < 0.05). The preoperative FEV1, FVC, FEV1/FVC and PEF of trial group compared with preoperative were significantly (P < 0.05). Even the difference of them compared with the same period control group were significantly (P < 0.05), except the FVC in the follow-up 3 years (P = 0.088).@*CONCLUSION@#The CRS may aggravate asthma symptoms and affect negatively the pulmonary function, and poor asthma control or aggravate may exacerbate the CRS in the course of CRS with asthma patient. With ESS based on combined therapy, it can improve the condition of CRS significantly and improve the control of asthma symptoms and pulmonary function else.
