In order to illustrate the effects of furfural, one of the most common inhibitory compounds in lignocellulosic hydrolysate, on oleaginous yeast Rhodotorula glutinis, we investigated the effects of different concentrations of furfural (0.1, 0.4, 0.6 and 1.5 g/L) on the biomass and lipid production of R. glutinis, as well as the effects of 1.0 g/L furfural on the utilization of glucose and xylose. Results showed that: when the furfural concentration reached 1.5 g/L, the lag phrase time was extended to 96 h, and the residual glucose was up to 17.7 g/L, with maximum biomass of only 6.6 g/L, which accounted for 47% of that in the basic medium (furfural-free), and the corresponding lipid content was reduced about 50%. Furfural showed lighter inhibitory degree on R. glutinis when xylose acted as the carbon source than glucose was the carbon source; more C18 fatty acids or unsaturated C18 fatty acids were generated in the presence of furfural.

Objective To understand the present situation and requirements of health education in schistosomiasis control in Hubei Province,so as to improve the health education to the targeted people. Method Through the questionnaire survey and field investigation,the data of the present situation and requirements of health education in schistosomiasis control were collect-ed in 24 counties(cities)of Hubei Province,and these data included the related institution structure of health education,basic information of personnel,equipment,funds,and health education working form. All the data collected were analyzed and evalu-ated. Results Among the 24 counties,there were 12 independent departments of health education,accounting for 50%. In terms of the basic information of the health education staff,the youngest person was 34 years old and the eldest was 58 years old,and the mean age was 46.55± 6.9 years. For the formal school education of the staff,5 had senior high school or below edu-cation (20.8%),16 had college education (66.7%),3 had bachelor degree or above (12.5%). There were 10 counties (41.70%)with the special funds for health education work but there were 3 counties(12.50%)without the special funds. Con-clusion The effectiveness of health education work in schistosomiasis control is remarkable,but there are still deficiencies in professional staff and funds in Hubei Province.

Sepsis is one of the leading causes of death in intensive care unit(ICU)patients,typically resulting from excessive inflammation induced by infection,leading to multiple organ dysfunction syndrome and life-threatening complications.Exosomes are a type of extracellular vesicle that are lipid bilayered nanoparticles secreted by cells.In recent years,numerous studies have demonstrated their involvement in the occurrence and development of sepsis.The various molecular substances carried by exosomes have been shown to regulate sepsis-related inflammation and organ damage.In particular,different types of exosomes hold promise as diagnostic biomarkers for sepsis patients,and also provide new therapeutic targets for improving patient outcomes.This review was conducted on the research progress concerning the relationship between exosomes and sepsis,sepsis associated-acute lung injury(SA-ALI),sepsis associated encephalopathy(SAE),sepsis associated-acute kidney injury(SA-AKI),sepsis associated cardiomyopathy(SIC),and other organ injuries related to sepsis.This study aims to assist in guiding clinical diagnosis and treatment.

Objective To analyze results of breast cancer screenings in the Cancer Screening Program in Urban China (CanSPUC) during 2012-2013. Methods In 14 cities of 9 provinces (Eastern Region: Beijing, Hebei, Liaoning, Shandong and Guangdong; Central Region: Heilongjiang and Hunan;Western Region: Chongqing and Gansu), 198 097 women aged 40-69 years who had lived in their cities for ≥3 years were surveyed through a cancer risk assessment questionnaire during 2012-2013. The questionnaires identified women considered to be at high risk for breast cancer, of whom 17 104 received screening examinations, for whom complete records of breast cancer screening and other data were available for 12 440 subjects altogether, including breast ultrasound exams for subjects 40-44 years old. Subjects older than 45 years or in whom breast imaging reporting and data system (BI-RADS) ultrasound had found≥3 lesions also underwent mammography. In this cohort, BI-RADS 3 class was defined as suspicious and BI-RADS ≥4 class as positive. Chi-square tests were used to compare breast cancer screening results by groups. Results As of October 2013, breast cancer screening percentages for the 12 440 subjects for whom full data were available were, by region, Eastern: 55.43% (6 895); Central: 21.45% (2 669); and Western:23.12% (2 876); by age, 40-44 years: 5.50% (684); ≥45 years: 94.50% (11 756). Using BI-RADS, 2018 subjects were found to have 3 lesions (detection rate:16.22%), which were distributed regionally as Eastern:19.00% (1 310 women), Central: 13.75% (367) and Western; 11.86% (341); χ2=91.45, P<0.001; and 289 were found to have≥4 lesions (detection rate:2.32%), which were distributed regionally as Eastern:2.41%(166), Central:1.54%(41) and Western;2.85%(82);χ2=11.04, P=0.004. Women aged 50-54 years had the highest detection rate of BI-RADS 3 lesions at 18.74% (561/2 994), and those aged 40-44 years had the highest detection rate of BI-RADS ≥4 at 2.92% (20/684). Conclusion Detection rates of BI-RADS ≥4 lesions were highest in the Western region and in women aged 40-44 years, and lowest in the Central region and in women aged 60-64 years. Detection rates of BI-RADS 3 lesions were highest in the Eastern region and in women aged 50-54 years and the lowest in the Western region and in women aged 60-64 years.

OBJECTIVE To study the quality grade stand ard of the premature Forsythia suspensa . METHODS A total of 138 batches of premature F. suspensa were collected from the main producing areas of F. suspensa in China. According to 2020 edition of Chinese Pharmacopoeia ，the contents of impurities ，moisture，ethanol-soluble extract ，volatile oil ，forsythin and forsythoside A in the premature F. suspense were determined ，and the qualified samples were screened. AHP-PCA mixed weighting method was used to give comprehensive weight to the indicators （except for the limit of impurity ）. The comprehensive score of the samples was calculated. The suggestions on the quality grade division of premature F. suspensa were put forward according to cluster analysis of K-mean value. RESULTS & CONCLUSIONS The contents of impurities ，moisture，ethanol-soluble extract ，volatile oil ，forsythin and forsythoside A in the premature F. suspense were 0-7.80％，1.60％-8.18％，13.13％-61.60％，0.21％-3.47％，0.02％-2.15％ and 0.79％-14.04％，respectively；average contents of them were 1.24％，4.97％，34.88％，2.01％，0.42％，6.86％，respectively. Totally 47 batches of 138 batches were qualified in all indexes.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is an independent risk factor for colorectal cancer (CRC), and the patients with CRC and T2DM have worse survival. The human gut microbiota (GM) is linked to the development of CRC and T2DM, respectively. However, the GM characteristics in patients with CRC and T2DM remain unclear. METHODS: We performed fecal metagenomic and targeted metabolomics studies on 36 samples from CRC patients with T2DM (DCRC group, n = 12), CRC patients without diabetes (CRC group, n = 12), and healthy controls (Health group, n = 12). We analyzed the fecal microbiomes, characterized the composition and function based on the metagenomics of DCRC patients, and detected the short-chain fatty acids (SCFAs) and bile acids (BAs) levels in all fecal samples. Finally, we performed a correlation analysis of the differential bacteria and metabolites between different groups. RESULTS: Compared with the CRC group, LefSe analysis showed that there is a specific GM community in DCRC group, including an increased abundance of Eggerthella , Hungatella , Peptostreptococcus , and Parvimonas , and decreased Butyricicoccus , Lactobacillus , and Paraprevotella . The metabolomics analysis results revealed that the butyric acid level was lower but the deoxycholic acid and 12-keto-lithocholic acid levels were higher in the DCRC group than other groups ( P < 0.05). The correlation analysis showed that the dominant bacterial abundance in the DCRC group ( Parvimonas , Desulfurispora , Sebaldella , and Veillonellales , among others) was negatively correlated with butyric acid, hyodeoxycholic acid, ursodeoxycholic acid, glycochenodeoxycholic acid, chenodeoxycholic acid, cholic acid and glycocholate. However, the abundance of mostly inferior bacteria was positively correlated with these metabolic acid levels, including Faecalibacterium , Thermococci , and Cellulophaga . CONCLUSIONS Unique fecal microbiome signatures exist in CRC patients with T2DM compared to those with non-diabetic CRC. Alterations in GM composition and SCFAs and secondary BAs levels may promote CRC development.
