Objective: To explore the intra class transmission pattern of acute hemorrhagic conjunctivitis (AHC) among students, so as to provide a basis for formulating precise prevention and control strategies. Methods: The data of AHC students in 2023 was obtained from the teacher-student health information module of the "Xiamen i-Education" platform. Taking the onset date from January 1st to December 31st, 2023 as the search criteria, the epidemiological data of confirmed AHC cases among students in the whole city in 2023 was collected. And the Knox test method was employed to quantify cluster risk at the class level. Subgroup comparisons were conducted to examine differences in cluster risk between academic stages and gender combinations. Cross analysis was performed to investigate the interactive effects of two characteristics on cluster risk. Results: In 2023, 708 cases of AHC students were reported in Xiamen, among which 54 class clustered outbreaks were identified. These outbreaks accounted for 40.54% of total cases. Among them, the incidence of class clustered outbreaks with male first onset cases was higher than that with female first onset cases ( χ 2=4.55, P <0.05). The class cluster risk was at a relatively high level within the incubation period (0-2 d) after AHC onset ( RR =4.61-6.43, P <0.05). Subgroup analysis revealed that female-female case pairs had a higher class cluster risk ( RR = 4.81- 10.29) compared to other gender combinations ( P <0.05). Primary school case pairs showed a higher risk ( RR =4.60-6.77) than middle school case pairs ( RR =3.85-4.57) (both P <0.05). Cross analysis indicated that primary school and female-female combinations had a higher risk ( RR =4.70-11.24) than other combinations, while middle school and male-female combinations showed a positive interaction ( RR =3.68-6.68)(both P <0.05). Conclusions AHC infection among students is primarily transmitted within classes. Gender and educational stage are key demographic factors influencing class cluster transmission risks. Transmission risks should be assessed by analyzing population characteristics and contact patterns, and targeted interventions should be implemented.

Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65％,69.16％ and 65.49％ of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72％,42.40％ and 18.25％ of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P＜0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P＜0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value ＜0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.

Objective: To clarify the predictive value for long-term prognosis of GRACE score and SYNTAX score in patients with non-ST elevation acute coronary syndrome (NSTE-ACS).
Methods: A total of 784 NSTE-ACS patients treated in our hospital from 2009-01 to 2014-01 were retrospectively studied. According to the treatment, the patients were divided into 3 groups: Medication group,n=410, Stent group,n=325 and CABG group,n=49. Based on 2 scoring systems, the patients were divided into another 3 groups: Low risk group, Medium risk group and High-risk group. The relationship between GRACE score and SYNTAX score was studied by Pearson correlation analysis, survival analysis was conducted by Kaplan-Meier method, univariate and multivariate analysis were performed by Cox proportional hazard model, and the area under curve (AUC) of ROC analysis was used to compare two methods.
Results: All 784 patients completed the follow-up study at the median of 47.7 months. Pearson correlation analysis showed that there was a weak positive correlation between GRACE score and SYNTAX score (r=0.40,P<0.01). Survival analysis presented that by GRACE score system, the MACE occurrence rates in Low risk group, Medium risk group and High-risk group were elevated accordingly as 13.81%, 23.64% and 36.55% respectively. And by SYNTAX system, MACE occurrence rates in Medium risk group and High-risk group were 39.29% and 37.93%, which were both higher than that in Low risk group (23.99%), while the scores between Medium and High risk groups were similar,P>0.05. Cox proportional hazard model and ROC analysis indicated that GRACE and SYNTAX scores had the important predictive value for lone term prognosis of NSTE-ACS. ROC analysis of GRACE score, SYNTAX score, the combination of GRACE and SYNTAX scores showed that 3 of them all had good predictive value for MACE occurrence, three of 95% CI had signiifcant overlapping without statistic differences.
Conclusion: GRACE score and SYNTAX score are related, both of them have important while similar predictive value for long term prognosis in NSTE-ACS patients, the combination of 2 scores cannot increase the predictive value. GRACE score is appropriate for the risk stratiifcation in NSTE-ACS patients.

Expressed sequence tags (ESTs) are widely used in gene survey research these years. The EST Pipeline System, software developed by Hangzhou Genomics Institute (HGI), can automatically analyze different scalar EST sequences by suitable methods. All the analysis reports, including those of vector masking, sequence assembly, gene annotation, Gene Ontology classification, and some other analyses, can be browsed and searched as well as downloaded in the Excel format from the web interface, saving research efforts from routine data processing for biological rules embedded in the data.
