Objective: To examine the effect of early comprehensive interventions on the physical growth and nerve development among premature infants, so as to provide insights into the follow-up management of premature infants after discharge from hospital. Methods: A total of 130 premature infants delivered in Shaoxing Municipal Maternal and Child Health Care Hospital from 2019 to 2021 were selected and divided into high- and low-risk groups according to gestational age and birth weight, while 306 full-term normal infants in the same hospital during the study period served as controls. All premature infants were given early comprehensive interventions until age of 12 months, including nutritional support and parental guidance of children's feeding and development, and all normal infants received periodical health checkup according to the basic public health service program. All infants received periodical measurements of height, weight and head circumference, and the 12-month intellectual and motor development ability was measured using the Bayley Scales of Infant Development revised in Chinese cities was used to assess. Infants' physical growth, mental development index (MDI) and motor development index (PDI) were compared among groups. Results: There were 130 premature infants with gestational ages of 28 to 36 weeks and birth weight of 1 200 to 3 440 g, including 79 male infants, and there were 80 infants in the low-risk group and 50 infants in the high-risk group. The full-term infants had a gestational age of 37 to 42 weeks, and birth weights of 2 500 to 4 000 g, including 162 male infants. There were significant differences in height (Wald χ2=28.664, P<0.001) and head circumference growth (Wald χ2=19.312, P=0.013) among the three groups as revealed by the generalized estimating equation; however, no significant differences were seen in the 12-month weight (F=0.639, P=0.528), height (F=1.051, P=0.350) or head circumference (F=0.318, P=0.728) among the three groups. The percentages of abnormal MDI were 2.00%, 0 and 1.31% among the high-risk premature infants, low-risk premature infants and full-term infants at ages of 12 months (χ2=1.319, P=0.517), while the percentages of abnormal PDI were 20.00%, 7.50% and 5.56% among the three groups at ages of 12 months (χ2=12.818, P=0.002). Conclusions Following implementation of early comprehensive interventions, the premature infants have favorable physical growth and comparable MDI with full-term infants; however, a high percentage of abnormal PDI is seen in high-risk premature infants. An improvement in the motor development among high-risk premature infants is recommended to be emphasized during the management of premature infants.

OBJECTIVETo study the relationship between the TCM Syndrome Differentiation-types of congestive heart failure (CHF) and thyroid hormones, including triiodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH), and atrial natriuretic peptide (ANP), as well as cardiac function parameters, including left ventricular ejection fraction (LVEF), mean velocity of circumferentid fiber shortening (mVcf) and A peak/E peak (A/E).

METHODSOne hundred patients with CHF were divided into 4 Syndrome Differentiation-type groups, their cardiac function parameters, ANP and thyroid hormones were determined and compared with those in the 23 subjects in the control group.

RESULTSIn CHF patients with edema and blood stasis Syndrome type, the level of plasma ANP was significantly higher than that in the control group (P < 0.05); level of T3 was significantly lower than that in the control group and in CHF patients of other three (Xin-qi deficiency, Yin-deficiency and blood stasis) Syndrome groups (P < 0.01, P < 0.01, P < 0.05 and P < 0.01); levels of LVEF and mVcf were significantly lower than those in the other three Syndrome groups (all P < 0.01). Level of T4 in other three Syndrome groups significantly increased than that in the edema and blood stasis Syndrome type. A/E value showed a higher level in patients of all TCM type than that in the control (P < 0.01). Correlation analysis showed that T3 was positively correlated with LVEF and T4 (r = 0.200, P < 0.05, and r = 0.293, P < 0.01), and negatively correlated with ANP (r = -0.263, P < 0.01); T4 was negatively correlated with A/E (r = -0.226, P < 0.05).

CONCLUSIONThe lowering of T3 and T4 and increasing of ANP may be one of the important reasons for lowering of LVEF in CHF patients with edema and blood stasis Syndrome-type. The decrease of T4 may be one of the important reasons for elevation of A/E and aggravation of left ventricular diastolic dysfunction in CHF patients of all the 4 TCM Syndrome-types.

Objective:To examine the association between macrophage migration inhibitory factor(MIF), Interleukin 6(IL-6), periodontal disease, and atherosclerosis in middle-aged and elderly individuals.Methods:This cross-sectional study enrolled 700 diabetic patients who were attending the endocrinology department of Beijing Hospital from January 2020 to December 2022.Out of these patients, 491 underwent a full-mouth periodontal examination.Among them, 106 were middle-aged and elderly.The study included 83 patients with complete data, aged between 45 and 70 years(mean age: 58.2±8.7 years).Among the included patients, 48 were male(57.8%)and 35 were female(42.2%).A questionnaire was administered to gather information about the patients, and serum levels of MIF and IL-6 were measured using enzyme-linked immunosorbent assay(ELISA).The relationship between serum MIF and IL-6 levels and periodontitis and atherosclerosis was evaluated through univariate and multifactorial analyses conducted on middle-aged and elderly individuals.Results:There were 66 cases(79.5%)in the periodontitis stage Ⅰ/Ⅱ group and 17 cases(20.5%)in the stage Ⅲ/Ⅳ group.The serum MIF levels in the two groups were(2, 312.5±795.0)ng/L and(2, 939.8±665.0)ng/L, respectively( P<0.01).Similarly, IL-6 levels were(3.5±3.0)ng/L and(6.7±6.1)ng/L in the two groups( P>0.05).The findings revealed that for each 1 ng/L increase in MIF serum levels, the risk of severe periodontitis and increased carotid intima-media thickness(cIMT)increased by 0.1%.Furthermore, for each 1 ng/L increase in serum MIF and IL-6 levels, the risk increased by 0.2% and 38.9% respectively.Serum MIF levels were found to be associated with atherosclerosis as well as with various factors related to periodontitis, including periodontal probing depth, bleeding index, clinical attachment level, periodontal probing depth≥4 mm sites, clinical attachment level≥5%, and bleeding index >2%(all P<0.05). Conclusions:This study investigates the correlation between MIF and IL-6 levels with Periodontal disease and Atherosclerosis in middle-aged and elderly individuals.
