Objective To investigate the fuction of tumor necrosis factor alpha(TNF-?),interleukin-1 beta(IL-1?) and interleukin-6(IL-6) in children with intracranial infection.Methods TNF-?,IL-1? and IL-6 levels of serum and cerebrospinal fluid(CSF) were determined in the purulent meningitis group(25 cases),tuberculous meningitis group(17 cases),viral meningitis group(30 cases)and control group(20 cases)by enzyme-linked immunosorbent assay(ELISA).Results The levels of TNF-?,IL-1? and IL-6 obviously increased in CSF compared with that in the serum (Pa

OBJECTIVETo study the chemical constituents of aerial parts of Ammopiptanthus mongolicus.

METHODIsolation and purification were carried out on silica gel, Sephadex LH-20 and HPLC column chromatography. The structures of the compounds were identified by physico-chemical properties and spectral analysis.

RESULTNine compounds were isolated and identified as (+)-maackiain (1), brevifolin (2), 7-hydroxy-4'-methoxy isoflavanone (3), daidzein 4',7-diglucoside (4), genistein 4', 7-di-O-beta-D-glucoside (5), isolupalbigenin (6), ononin (7), beta-sitosterol (8), beta-daucosterol (9).

CONCLUSIONCompounds 2, 4 - 6 were obtained from the genus Ammopiptanthus for the first time.

OBJECTIVETo evaluate the effect of sustained-release alpha-lipoic acid tablets (SRLA) on blood lipid, glucose and insulin levels in hyperlipidemic New Zealand rabbits.

METHODSTwenty-four New Zealand rabbits were randomized into normal diet group, high-fat diet group, and high-fat diet + SRLA (300 mg/tablet) group with corresponding feed. At the beginning and 4 weeks after the feeding, the serum levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), blood glucose, and serum insulin were measured, and insulin sensitivity index (ISI) was calculated.

RESULTSFour weeks after feeding with high-fat diet, the insulin levels was elevated and the ISI lowered in the New Zealand rabbits, indicating successful establishment of the animal model of hyperlipidemia. Compared with the high-fat diet group, the serum levels of TG, TC, LDL-C and insulin were significantly reduced (P<0.05), and the ISI was significantly increased (P<0.05) in high fat diet + SRLA group. But no statistically significant difference was found in the blood glucose among the 3 groups.

CONCLUSIONSRLA can significantly correct blood lipid and insulin disorders in hyperlipidemic New Zealand rabbits and prevent the occurrence of insulin resistance and hyperlipidemia.

OBJECTIVETo understand factors as social support, situation of depression and related risk factors among migrant women of reproductive age in some areas of Wuhan.

METHODSCluster sampling method and face-to-face interview with structured questionnaire were used to investigate 316 migrant women in Wuhan.

RESULTSThe overall prevalence rate of depression was 32.3%.

RESULTSfrom binary logistic regression analysis showed that factors as: under pressure (OR = 4.010, 95%CI: 1.672 - 9.617), having had negative life events (OR = 2.050, 95%CI: 1.170 - 3.591) or tight relations with neighbors (OR = 2.537, 95%CI: 1.053 - 6.113), not quite satisfied (OR = 4.247, 95%CI: 1.521 - 11.855) or satisfied (OR = 2.411, 95%CI: 1.111 - 5.233), on his/her own health status etc., might serve as the possible risk factors for depression. In scores related to social support, and the utilization of such support, there were statistically significant differences seen between the groups with depression and the one without.

CONCLUSIONThe prevalence of depression among migrant women of reproductive age appeared to be high in some areas on Wuhan. Factors as: under pressure, having had negative life events, tight relations with neighbors, status on satisfaction of one's own health situation as well as related social support, seemed to be the main risk factors for depression in this population.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.
