Objective To assess the structure validity of application of sub-health measurement scale version 1.0(SHMS V1.0)in college students in Guangzhou City to lay a foundation for further analyzing the healthy status in this group and its influen-cing factors.Methods Nine hundreds college students were selected by adopting the stratified random sampling method for conduc-ting the questionnaire survey.The SPSS20.0 and AMOS21.0 were adopted to conduct the exploratory factor analysis(EFA)and confirmatory factor analysis(CFA)respectively.Results EFA obtained 7 factors with eigenvalue more than 1,the cumulative vari-ance contribution rate was 56.766%,moreover 7 factors were basically consistent with the theoretical structure of SHMS V 1.0. CFA conducted the model fitting for 3 total scales and 3 subscales,the results showed that the fitting of 3 subscales was good,the fitting result of total scale could be accepted,but did not reach the desired effect.Therefore,five times modification was applied in the total scale,and the fitting indexes after modification were CMIN/DF=2.723,GFI=0.907,IFI=0.917,TLI= 0.905,CFI=0.917,RMSEA=0.046,the fitting effect was comparatively excellent.Conclusion The dimension division of sub-health measure-ment scale is basically reasonable,and using this scale for measuring the sub-health status of college students in Guangzhou City has a better structure validity.

Objective To analyze the clinical manifestations of pulmonary fungal disease in patients with different pathogen infection and different immune states. Methods A retrospective analysis was carried out with the clinical data of 78 patients with pulmonary fungal disease who were treated in Fujian Provincial Hospital from June 2012 to June 2016. Results The identified pathogens included Cryptococcus (78.2％, 61/78), Aspergillus(17.9％, 14/78), Talaromyces marneffei, Mucor, and Trichosporon asahii (one each). Cryptococcus was mostly found in healthy individuals without underlying disease and Aspergillus largely infected those with underlying disease. Diabetes mellitus was the most common underlying disease. Pulmonary fungal infection was confirmed by pneumonectomy (41.0％, 32/78), CT-guided percutaneous transthoracic biopsy (43.6％, 34/78), transbronchial lung biopsy (14.1％, 11/78), or blood culture (1.3％, 1/78). Pulmonary cryptococcosis was often asymptomatic (47.5％, 29/61). Hemoptysis was only found in the patients with underlying disease. The patients with pulmonary aspergillosis showed higher prevalence of hemoptysis (57.1％, 8/14) than the patients with other pulmonary fungal diseases. Bronchoscopy usually gave negative finding in case of pulmonary cryptococcosis (77.8％, 14/18). Inflammatory exudation was the primary finding of pulmonary aspergillosis (6/10). Intraluminal necrosis and neoplasia were only found in the aspergillosis patients with underlying disease. The primary imaging findings in pulmonary cryptococcosis was nodule or mass (78.7％, 48/61). Halo sign and crescent sign were rarely found in pulmonary aspergillosis. Of the 78 patients, 45 (57.7％) patients received pharmacological therapy alone, 15 (19.2％) surgical treatment alone, and 18 (23.1％) received drugs in combination with surgery. Six patients died, 25 lost to follow-up, and 47 with stable disease. Conclusions The clinical characteristics of pulmonary fungal disease vary with the pathogen and the immune states of patients. Clinical symptoms and immune status of patients should be taken into account when making diagnosis of pulmonary fungal disease for the purpose to speculate the probable fungal pathogen and choose the most appropriate diagnostic tool.

Objective To establish the norms of Self-rated Health Measurement Scale Version 1. 0 ( SRHMS V1.0) for urban residents in Guangdong. Methods We used regional stratified random sampling method to select 6000 urban residents of 5 cities in Guangdong ( including Guangzhou, Maoming, Shantou, Shaoguan and Shenzhen) for a questionnaire investigation with SRHMS V1. 0, and establish the norms of mean,percentile and threshold based on characteristics of SRHMS V1.0 scores. Results The residents can be divided into 8 groups on the basis of gender and cut-off point of age 40,50 and 60. The mean norms of SRHMS V1.0 total scores were:(78.57±10.10),(76.93±9.90),(75.33±10.66),(69.45±13.90)for males under age40,40-50,50-60 and above 60 respectively;(77.03±10.00),(74.55±10.27),(72.24±11.76), (66.48±14.37)for females under age40,40-50,50-60 and above 60 respectively. The percentile norms of SRHMS V1.0 from 5 percent to 95 percent were established with 5% as interval. The norms of cutting off scores were established as five states according to the scores of TS,namely severe poor health,poor health,gen-eral health,good health and fairly good health,with( x-s),( x-0.5s),( x+0.5s),( x+s) as cutting off scores. Conclusion The study established the SRHMS V1.0 norms for urban residents of Guangdong preliminarily,which provides reference for further research of the population''s health status and its impacting factors.

OBJECTIVE To explore the relationship between the point mutations of gene CYP51 and the azole-resistance mechanism in clinical Candida albicans isolates.METHODS The paper diffusion test and NCCLS M-27 protocols were used to screen the fluconazole-resistant and itraconazole-resistant C.albicans clinical isolates.Gene CYP51 of two azole-resistant C.albicans clinical strains(2007H and 2007T strains) was amplified by three pairs of primers,respectively.The PCR products purified were sequenced,and compared with the nucleotide sequences of C.albicans(accession No.:X13296) to find out the mutation sites.RESULTS The nucleotide sequence analysis showed that there were both significant point mutations and silent mutations in gene CYP51 from two azole-resistant isolates of C.albicans.Seven mutations previously described,F105L,K128T,Y132H,T199I,R267H,G464S,and R467K,were identified in the two strains.The animo acid substitutions of Y132H and R467K,known to contribution to azole resistance,were detected in both 2007H strain and 2007T strain.Four novel mutations,including F71L,W244R,T311N and T352I,were simultanously identified.Nine silent mutations appeared in two isolates.CONCLUSIONS In this survey,the two azole-resistant C.albicans clinical isolates contained more than one mutation in gene CYP51 that is associated with azole resistance.Four novel mutations of CYP51 may be associated with the resistance of C.albicans to azoles.And the mechanisms need to be further studied in detail.
