Objective To investigate the therapeutic effect of Qingyan Mixture for laryngeal cough patients with lung dryness due to yin deficiency. Methods Sixty laryngeal cough patients with lung dryness due to yin deficiency were evenly randomized into treatment group and control group. The treatment group was given oral use of Qingyan Mixture, and the control group was given oral use of Ketotifen and Carbetapentane. The course of treatment for both groups lasted for 10 days. The overall therapeutic effect, and the effect on individual symptom or sign were evaluated after treatment. Results ( 1) In the treatment group, six patients were cured, 14 were markedly effective, 8 were improved, 2 were ineffective and the total effective rate was 93.3%. In the control group, one case was cured, 7 were markedly effective, 17 were improved, 5 were ineffective and the total effective rate was 83.3%. The overall clinical effect in the treatment group was significantly higher than that in the control group (P<0.01) . (2) As for the effect on individual symptom or sign, the treatment group showed stronger effect on dry cough than the control group ( P<0.01) , while differences of dry pharynx, throat itching, foreign body sensation in the throat, and pharyngeal signs were insignificant between the two groups (P>0.05) . (3) After treatment, the total scores of main symptoms were decreased in both groups (P<0.05 or P<0.01) compared with those before treatment. Conclusion Qingyan Mixture shows certain effect on relieving symptoms and signs of laryngeal cough patients with lung dryness due to yin deficiency.

Objective To investigate the sore-throat-relieving, anti-inflammation and antitussive actions of Qingyan mixture on the animal models. Methods Sore-throat-relieving action of Qingyan mixture was observed in SD rats with acute pharyngitis induced by spray of ammonia water at volume fraction of 15%. Anti-inflammation action of Qingyan mixture was observed on mice model of xylene-induced ear edema, and antitussive action of Qingyan mixture was carried out in mice with cough induced by concentrated ammonia spray. Results (1) The results of sore-throat-relieving action of Qingyan mixture showed that the infiltration of inflammatory cells did not happen in the blank control group, but moderate/severe inflammatory cell infiltration was shown in the model group. In the positive group, 4 rats had slight inflammatory cell infiltration while the left 6 rats had no inflammatory cell infiltration. Low-dose Qingyan mixture group had no inflammatory cell infiltration in one rat, and had slight infiltration in 9 rats. In middle-and high-dose Qingyan mixture groups, 4 rats had no infiltration and 6 had slight infiltration, inflammatory cell infiltration was markedly relieved ( P<0.01) and the sore-throat-relieving action in both groups was similar to the positive medicine of Guilin mirabilitum praeparatum (P>0.05). ( 2) The anti-inflammation rate was 69.8% in the positive control group, and was 27.3%, 60.4%, 60.0% in low-, middle- and high-dose Qingyan mixture groups respectively. The inhibitory effect of middle-and high-dose Qingyan mixture on xylene-induced mice ear edema was similar to that of the positive control group ( P>0.05) . ( 3) The cough-relieving rate was 42.6%, 139.0%, 64.3%, 104.0% in positive control group, and low-, middle-and high-dose Qingyan mixture groups respectively. Mice cough latent was obviously prolonged and cough frequency was decreased in the three Qingyan mixture groups, the differences being significant compared with the model group ( P<0.05 or P<0.01) . Conclusion Qingyan mixture has certain sore-throat-relieving, anti-inflammation and antitussive actions, which can be used for the treatment of patients with actue/chironic laryngitis and the complication of cough.

Objective To study infection of the lung tissue by bronchoalveolar lavage for BALF and explore whether GM can help improve the he diagnosis efficiency in patients without granulocyte deficiency with IPA, and find the threshold of GM values. Methods Between January 2011 and December 2011, 173 cases of patients were considered possible invasive pulmonary aspergillosis in parallel BALF GM detection in the center of the respiratory endoscopic examination.. According to the diagnostic criteria at home and abroad, all the cases were divided into four groups, including group of IPA, group of tuberculosis, group of bacterial pneumonia and group of non-infection. Using ELISA method for determination of serum and BALF GM. The diagnostic value was made by statistical methods in BALF GM detection without patients of granulocyte deficiency with IPA. Results There were 11 cases in the group of IPA, 23 cases in the group of tuberculosis, 90 cases in the group of bacterial pneumonia and 49 cases in the group of non-infection. In patients without granulocyte deficiency with IPA,BALF GM value was higher comparing with the patients without IPA. There were significant difference between the two groups; Comparing the GM value in the serum, the detection of BALF GM was higher in IPA. ROC curve analysis found that when the BALF GM test value was 0.95 or higher, there was highest possible with IPA. Conclusion BALF GM testing is beneficial to patients of invasive pulmonary aspergillosis without granulocyte deficiency in early identification with IPA. This study found that BALF GM best value is 0.95 or higher.

Objective To characterize clinical feature, frequency of isolation and antimicrobial susceptibility of pathogens isolated from patients with nosocomial bloodstream infections in Huashan Hospital, Fudan University from 1995 to 2004. Methods The clinical data of all patients who were diagnosed with nosocomial bloodstream infections based on national diagnostic criteria of nosocomial bloodstream infections were retrospectively analyzed. The pathogens were routinely isolated and identified. Susceptibilities against antimicrobial agents were determined by Kirby-Bauer methods and analyzed by WHONET 5.0 software. Results During the 10-year study period, a total of 395 patients were diagnosed with nosocomid bloodstream infection with 435 strains isolated from blood specimen.Gram positive bacteria, Gram negative bacilli and fungi, accounted for 47.4%, 45.1 % and 7.6%,respectively. Coagulase-negative Staphylococci (21.4%), S. aures (17.9%), E.coli (13.6%), K. pneumoniae (10.8%), Candidaspp (7.4%), Enterococci (6.0%), Pseudomonasspp (6.0%) and Acinetobacter spp (3.7%) were frequently identified isolates. S. aures and coagulase-negative Staphylococci resistant to methicillin were 62.8% and 87.1%, respectively. The susceptibilities of cefotaxime and ceftazidime against E. coli and K. preumonine were 46%-78% and 27.7%-40.4%, respectively. Conclusions The Gram positive cocci are slightly more prevalent than Gram negative bacilli in nosocomial bloodstream infections and resistance to the first line antibiotics is common among all pathogens isolated. Candida spp is the fifth leading cause of nosocomial bloodstream infections.

The amplified VP2 gene (PPV strain SC-1) and PCV20RF2 gene were inserted into the eukaryotic expression vector pPI-2.EGFP.Then the recombinant plasmid named pPI-2.EGFP.VP2.ORF2 was obtained.Mediated by liposome,the recombinant plasmid was transfected into Veto cells and expressed.Using immunofluorescence assay,the fluorescence of expression products were first detected at 20 h after transfection and peaked 36 h.Under electronmicroscope,virus-like particles (VLPs) can be observed in the transfected cells.To confirm the obtained VLPs to be recombinant particles,piglets were immunized using purified VLPs.The dynamic variation of blood T lymphocytes and serum antibody level of PPV and PCV2 were measured.The results showed that the ratio of CD3+,CD4+ T lymphocyte in peripheral blood lymphocyte of immunized piglets raised in a certain degree,the number of CD8+ T lymphocytes fell at 7-14 d after immunization,and then raised.Relatively high level of PP-V,PCV2 specific antibody could be detected.This indicated that the expression of recombinant plasmid pPI-2.EGFP.VP2.ORF2 was successful,the virus-like particles were formed and showed favourable immunogenicity.
