Methods: Twenty-nine HIV-infected patients were treated with ZY-2 for 3 months as one treatment course; and viral load, immune function and symptoms-signs were determined before and after treatment. Results: After treatment, the absolute values of CD4 were elevated in 8 cases, and lowered in 14 cases, 7 cases were not changed; the ratio of CD4/CD8 were elevated in 2 cases, lowered in 1 case, 16 of them were not changed obviously. The CD4 and CD4/CD8 ratio were elevated simultaneously in 2 cases. Neopterin lowered in 4 cases, elevated in 11 cases, and not changed in 1 case. Viral load (VL) was lowered in 6 cases, elevated in 8 cases and not changed in 2 cases. The total effective rate was 42.28% on the basis of comprehensive assessment of VL, immune function, body weight and symptoms-signs. Conclusion: ZY-2 is an effective Chinese recipe in treating HIV-infected patients.展开更多

We also investigated the procedure of diagnosis us well as the empirical treatment for this disease in OPD ( outpatient department) of pulmonary disease. Methods A total of 7097 patients from 150 hospitals in 24 provinces in China were enrolled in the study from Nov. 2002 to Mar. 2003. Every patient was diagnosed, treated and registered at the same time. Diagnostic behavior for doctors include chest radiograph and/or CT examination of the lung, as well as collecting sputum samples at the time of diagnosis for bacteria culture to identify the pathogen. Appointed staff fulfiUed the questionnaires and information sheets in each center. After that, data were computerized and analyzed. Results There were 7404 valid information sheets and 7097 questionnaires taken into count. The majority CAP patients were from cities ( 77. 3% ), most of those who had medical insurance. Most CAP patients had productive cough (81.1% ), and 76. 7% and 18. 2 % CAP patients received chest film and CT examination respectively for diagnosis. Only 24% patients received sputum sample tested and with 36% got positive results. Streptococcus pneumoniae remained the main pathogen of CAP (43. 2% ). Most doctors used to prescribe β-lactam antibiotics as the first line of empirical therapy of CAP ( 51.1% ) with oral taken as the main method for drug using (66. 3% ). Conclusion This survey provides a key point of empirical therapy in China. The procedure for diagnosing us well as the empirical treatment of CAP in OPD of pulmonary disease in China still to be improved, especially in accessing the pathogen. Guidelines developed to recognize and evaluate CAP should base on epidemiological information of the pathogen prevalence, then could offer a rational approach to the initial management of the CAP patients.展开更多
