Objective To analyze the relationship between clinical and pathological features in children with Henoche-Sch?nelin purpura nephritis (HSPN). Methods Clinical and pathological data of 89 children with HSPN from April 2009 to April 2013 in our hospital were retrospectively analyzed. Results A majority of patients (94.83%) suffered nephritis within two month after purpura. Clinically, hematuria and proteinuria (41.6%), nephrotic syndrome (27.0%), and isolated protein-uria (21.3%) are the most common type in children with HSPN. The majority of pathological changes of these three types HSPN are gradeⅢ, which accounts for 67.6%, 70.8%, and 73.7%, respectively. The clinical manifestations are closely associated with pathologic classiifcation (H=26.88, P=0.000). IgA plus IgM deposit was the most common type (40.45%) in histological and immunopathologic changes.There was no statistical difference between the pathologic classification and immunopathologic types. Gastrointestinal bleeding was associated with pathologic classiifcation. Conclusions The pathological changes of HPSN patients are mainly of gradesⅡandⅢ, and the clinical manifestations, gastrointestinal bleeding in particular, are closely associated with pathological classiifcation.

The purpose of this study was to prepare dabigatran etexilate nanoemulsion to improve bioavailability of dabigatran etexilate, a poorly water-soluble drug. The physicochemical properties and the stability of dabigatran etexilate nanoemulsion were investigated. Equilibrium solubility of dabigatran etexilate in commonly used oil materials for nanoemulsion were determined for selection. Then, surfactant and co-surfactant were chosen based upon the plooted pseudo-ternary diagrams. The formulation and preparation process were further optimized with orthogonal design. As a result, the dabigatran etexilate nanoemulsion was formulated based on the system consisting of Oil Acid/Labrafac Lipophile WL1394/Cremophor RH40/Transcutol P/H2O. The dabigatran etexilate nanoemulsion was found to have a mean diameter of(57. 5±0. 2)nm, Zeta potential of -(20. 9±1. 4)mV, and the drug encapsulation efficiency of(85. 2±1. 0)%. Besides, the droplet size, stability constant and drug content of the nanoemulsion was found to have no significant changes in at least 3 months under room temperature. In conclusion, the uniform and stable dabigatran etexilate nanoemulsion with a clear and translucent appearance was obtained after the optimization of formulation and preparation process. Thus nanoemulsion could be a promising way for the improvement of bioavailability of dabigatran etexilate and other poorly water-soluble drugs.

Objective:To explore applications of essential balm K-point stimulation on the swallowing rehabilitation in patients with minimally consciousness state, so as to provide reference for patients rehabilitation.Methods:This was a prospective randomized controlled study. A total of 60 minimally consciousness state patients were enrolled by convenience sampling method from Henan Provincial People Hospital from January to December 2021, who were divided into experimental group and control group according to the random number table method, with 30 cases in each group. Both groups received routine rehabilitation therapy, based on this, the control group was given routine K-point stimulation, the experimental group implemented essential balm K-point stimulation. Before and after 4 weeks of intervention, the Kubota water swallowing test and Coma Recovery Scale-revised (CRS-R) was used for assessment.Results:Before intervention, there was no significant difference in Kubota water swallowing test grade and CRS-R scores between two groups (both P>0.05). After 4-week intervention, Kubota water swallowing test Ⅰ-Ⅴ grade were 1, 6, 13, 7 and 3 cases in the control group, while 4, 12, 8, 3 and 3 cases in the experimental group, the difference was statistically significant ( Z = 2.09, P<0.05); the scores of oral motor/verbal function scale were (2.60 ± 1.16) in the experimental group, higher than in the control group (1.90 ± 0.32), the difference was statistically significant ( t = 2.18, P<0.05). Conclusions:Essential balm K-point stimulation can effectively promote swallowing function of patients with minimally consciousness state, and improve patient′s oral motor function.

OBJECTIVETo investigate the relationship between maternal pre-pregnancy body mass index, weight gain during pregnancy and small for gestational age (SGA) birth so as to provide evidence for the development of comprehensive prevention programs on SGA birth.

METHODSBetween March, 2012 and July, 2014, 4 754 pregnant women were asked to fill in the questionnaires which were collected from the First Affiliated Hospital of Shanxi Medical University. Data related to general demographic characteristics, pregnancy and health status of those pregnant women was collected and maternal pre-pregnancy body mass index and maternal weight gain were calculated. Subjects were divided into different groups before the effect of maternal pre-pregnancy body mass index and weight gain during pregnancy on SGA birth were estimated.

RESULTSThe overall incidence of SGA birth was 9.26% (440/4 754). Proportions of SGA birth from pre-pregnant, underweight group, normal weight group, overweight and obese groups were 9.85%, 8.54% and 9.45%, respectively. Results from multi-factor logistic regression analyses showed that after adjusting the confounding factors as age, history on pregnancies etc., women with high pre-pregnancy BMI showed a lower incidence of SGA than those under normal pre-pregnancy BMI (OR = 0.714, 95% CI: 0.535-0.953). Different weight gains during pregnancy were statistically significant (χ(2) = 8.811, P = 0.012). Incidence of SGA birth that was below the recommended range in the 2009 Institute of Medicine Guidelines (12.20%) was higher than those within (9.23%) or beyond (8.45%) the recommended range. Results from the multi-factor logistic regression analyses showed that, after adjusting the confounding factors as age, pregnancy history etc., factor as weight gain below the recommended level could increase the risk of SGA (OR = 1.999, 95% CI: 1.487-2.685). In the underweight, normal weight, overweight or obese groups, with weight gain during pregnancy below the range, the incidence of SGA showed an increase (OR = 2.558, 95% CI: 1.313-4.981, OR = 1.804, 95% CI: 1.258-2.587, OR = 3.108, 95% CI: 1.237-7.811). There was no interaction of addictive or multiplicative models between these two factors under 'interaction analysis'.

CONCLUSIONWomen with high pre-pregnancy BMI presented a lower incidence of SGA than those within the normal range. Insufficient weight gain during pregnancy could increase the risk of SGA delivery. These findings called for attention to be paid to the gestational weight gain, in order to decrease the risk of SGA.

BACKGROUNDAberrant epithelial repair has been observed in chronic rhinosinusitis (CRS) patients; however, the mechanism of epithelial cell repair regulation is unclear. Epidermal growth factor (EGF) plays an important role in regulating epithelial cell repair in lower airway and may be a critical factor in the remodeling processes of CRS. The objective of our research is to evaluate the differences between CRS and normal subjects and between chronic rhinosinusitis without nasal polys (CRSsNP) and chronic rhinosinusitis with nasal polys (CRSwNP) in the regulation of EGF pathways and the regulating proliferative position of classic Ras/Raf/MEK/ERK pathways.

METHODSWe evaluated the proliferation rates of ethmoidal mucosal cells before and after stimulation with EGF, epidermal growth factor receptor (EGFR) kinase inhibitor AG1478, and extracellular signal-regulated kinase 1/2 (ERK1/2) inhibitor PD98059 using MTT assays. We also analyzed the sinonasal epithelial cells collected from control subjects and patients with CRS subtypes CRSsNP and CRSwNP for the expression of ERK1/2, phosphorylated ERK1/2, P21, P15, and P27 using western blotting analyses.

RESULTSThe proliferation rates of sinonasal epithelial cells before and after EGF stimulation were lower in CRS patients than in the controls. AG1478 or PD98059 inhibitor treatment of control epithelial cells did not result in a significant difference in proliferation. Although, AG1478 and PD98059 inhibited the proliferation of CRS cells, the degree of proliferation inhibition was markedly different in CRSsNP. AG1478 suppressed the proliferation of CRSwNP epithelial cells, whereas PD98059 had no effect. The ratio of ERK1/2 phosphorylation in CRS cells was lower than that of the control cells. Cyclin-dependent kinase inhibitors were highly expressed in CRS cells compared with that of control cells. ERK1/2 and P27 showed differential expression in CRSsNP and CRSwNP.

CONCLUSIONSDifferences existed in EGF pathways in CRS patients and normal subjects as well as in CRSsNP and CRSwNP. Classical Ras/Raf/MEK/ERK pathway may assume absolute superiority in control cells. Ras/Raf/MEK/ERK classical pathway and other pathways might be active at the same time to stimulate epithelial cell proliferation in CRSsNP. The function of Ras/Raf/MEK/ERK classical pathway was weaker in CRSwNP than in CRSsNP and when the classical pathway was blocked in CRSwNP, some other pathway could have completely compensated the proliferation induced by the Ras/Raf/MEK/ERK pathway.
