OBJECTIVETo study the status and problems of complementary feeding behavior for infants aging between 6 - 24 month-old in urban and rural areas of Chengdu in 2011.

METHODSA total of 1283 infants aging between 6 - 24 month-old, including 601 from urban area and 682 from rural area, were randomly selected by stratified cluster random sampling method, and divided into three groups as 6 - 8, 9 - 11 and 12 - 24 month-old groups, between March and April in 2011. Information of complementary feeding behavior were collected by questionnaire, and then assessed, quantified and compared by standards. The evaluation system was established (the total score was 24), and was used to assess among children aging 6 to 24 month-old in urban and rural areas in Chengdu.

RESULTSThe average score for infants in Chengdu was 18.6 ± 2.5, accounting for 77.6% of the total score. The scores of food selection and preparation were highest (90.7% of total score) among the behavior, and the scores of caregiver's behavior, infants behavior, feeding environment and environmental hygiene were low (about 75.2% - 77.6% of total score). The average score in urban and rural groups were separately 19.8 ± 2.1 and 17.6 ± 2.4, the score in urban group was higher than that in rural group (P < 0.05), occupying total score 82.3%, 73.4%, respectively. The average score in 6 - 8 month, 9 - 11 month and 12 - 24 month groups were separately 18.9 ± 2.3, 19.1 ± 2.4, and 18.2 ± 2.6, occupying total score 78.9%, 79.4% and 75.7%, respectively. The score in 6 - 8 and 9 - 11 month groups were higher than that in 12 - 24 month group (P < 0.01). The pass rate (above 60% of total score) was 94.2% and excellent rate (above 80% of total score) was 44.8% in Chengdu. The excellent rate in urban and rural groups were separately 65.7% and 26.4% (χ(2) = 199.825, P < 0.01).

CONCLUSIONThe complementary feeding behavior for infants was not optimistic in Chengdu, and the behavior was even worse in rural areas and among elder infants groups.

Seventy-nine injectable herb extractions have been approved by the Chinese Food and Drug Administration (CFDA) and are frequently administered intravenously for various diseases. Unfortunately, herb-drug interactions are under-investigated and sometimes overlooked in the clinic. In the present investigation the in vitro inhibition of 9 drug metabolizing enzymes including CYP1A, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A was assessed using an appropriate probe substrate for each enzyme with human liver microsomes. Metabolite formation was quantified using a validated and sensitive high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay. The IC₅₀ of each herb extract was estimated using a concentration range from 5% to 0.5%, and the time-dependent inhibition of the nine CYP450 isoenzymes was also determined. Of the 79 approved iv herb injectables, 37 inhibited CYP1A, 24 inhibited CYP2A6, 41 inhibited CYP2B6, 36 inhibited CYP2C8, 31 inhibited CYP2C9, 41 inhibited CYP2C19, 13 inhibited CYP2D6, 25 inhibited CYP2E1, and 42 inhibited CYP3A with 50% or greater inhibition at a test concentration of 5% (v/v). IC₅₀ differences were noted between pre-incubation or co-incubation assays with HLM for 30 min, with the time-dependent inhibitory (TDI) effects were observed with 2 injectables on CYP1A, 5 injectables on CYP2A6, 5 injectables on CYP2B6, 6 injectables on CYP2C8, 1 injectable on CYP2D6 and 6 injectables on CYP3A. Collectively, the results demonstrate that potential herb-drug interactions (HDIs) can occur with the concomitant use of herb injectables and prescription drugs that are cleared by CYP450 enzymes, and further investigation is warrant for the clinical relevance of these interactions.

Objective To explore and analyze the risk factors of severe falciparum malaria cases,and to provide evidence for early clinical prevention and intervention measures. Methods A total of 114 imported cases of falciparum malaria in Wuhan from March 2012 to November 2019 were selected,divided into mild group(n=87)and severe group(n=27),and logistic regression analysis was performed on the risk factors of severe disease. Results There were significant differences in length of stay, erythrocyte, hemoglobin, platelet, urea, creatinine, albumin, creatine kinase isoenzyme, lactate dehydrogenase, urine occulting blood and urine protein between mild group and severe group (P<0.05).Multivariate Logistic regression analysis showed that alanine aminotransferase (OR=0.167, 95%CI: 0.042-0.668), albumin (OR=24.843, 95% CI: 5.170-119.383), urea (OR=0.240,95%CI: 0.074-0.779) and occulted blood in urine (OR=0.204, 95%CI: 0.062-0.672) were independent influencing factors for the occurrence of severe falciparum malaria. Conclusion Patients with liver function damage and alanine aminotransferase increased by more than 2 times(≥80U/L),albumin decreased(<30g/L),renal function damage,increased urea nitrogen,hematuria and other abnormal results, the possibility of severe falsiparum malaria development should be highly suspected.

Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.
