Use of antenatal corticosteroids among infants with gestational age at 24 to 31 weeks in 57 neonatal intensive care units of China: a cross-sectional study

Background:Antenatal corticosteroids(ACS)can significantly improve the outcomes of preterm infants.This study aimed to describe the ACS use rates among preterm infants admitted to Chinese neonatal intensive care units(NICU)and to explore perinatal factors associated with ACS use,using the largest contemporary cohort of very preterm infants in China.Methods:This cross-sectional study enrolled all infants born at 24^(+0)to 31^(+6)weeks and admitted to 57 NICUs of the Chinese Neonatal Network from January 1st,2019 to December 30th,2019.The ACS administration was defined as at least one dose of dexamethasone and betamethasone given before delivery.Multiple logistic regressions were applied to determine the association between perinatal factors and ACS usage.Results:A total of 7828 infants were enrolled,among which 6103(78.0%)infants received ACS.ACS use rates increased with increasing gestational age(GA),from 177/259(68.3%)at 24 to 25 weeks’gestation to 3120/3960(78.8%)at 30 to 31 weeks’gestation.Among infants exposed to ACS,2999 of 6103(49.1%)infants received a single complete course,and 33.4%(2039/6103)infants received a partial course.ACS use rates varied from 30.2%to 100%among different hospitals.Multivariate regression showed that increasing GA,born in hospital(inborn),increasing maternal age,maternal hypertension and premature rupture of membranes were associated with higher likelihood to receive ACS.Conclusions:The use rate of ACS remained low for infants at 24 to 31 weeks’gestation admitted to Chinese NICUs,with fewer infants receiving a complete course.The use rates varied significantly among different hospitals.Efforts are urgently needed to propose improvement measures and thus improve the usage of ACS.

Glomerular chemokine expression and the effect of steroid and cyclophosphamide pulse therapy in human crescentic glomerulonephritis

OBJECTIVE: To study glomerular expression of C-C chemokines, monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1alpha and beta (MIP-1alpha, MIP-1beta) and the effect of steroid and cyclophosphamide (CTX) intermittent intravenous pulse therapy on expression in patients with crescentic glomerulonephritis (CGN) to further investigate the underlying mechanism of the treatment. METHODS: Twelve patients with initial biopsy-proven CGN(2), 6 with lupus nephritis (lupus-CGN, LN-CGN) and 6 with vasculitis, (vasculitis-CGN, V-CGN) were enrolled in this study. They underwent an initial biopsy before steroid and CTX intermittent intravenous pulse therapy and were biopsied again one to three months later. Expression of MCP-1, MIP-1alpha, MIP-1beta, and CD68 in glomeruli with cellular and fibrocellular crescents were examined by immunohistochemical analysis in serial sections of renal biopsies. The effect of the pulse therapy on histopathological changes was also observed. RESULTS: Although steroid and CTX intermittent intravenous pulse therapy markedly reduced the degree of glomerular crescent formation both in LN-CGN and V-CGN, the effect of the therapy on glomerular chemokine expression was significantly different between LN-CGN and V-CGN. It was found that steroid and CTX intermittent intravenous pulse therapy reduced the expression of CD68, MCP-1, and MIP-1alpha, but had no effect on MIP-1beta in glomeruli with cellular crescents of patients with LN-CGN. In patients with V-CGN, the therapy also reduced the expression of CD68, but had no effect on MCP-1, MIP-1alpha, and MIP-1beta in glomeruli with cellular crescents. It was noted that the degree of glomerulosclerosis and tubular interstitial fibrosis increased more significantly at the second biopsy in V-CGN as compared to LN-CGN. CONCLUSIONS: The efficacy of steroid and CTX intermittent intravenous pulse therapy in CGN might be affected by reduction of glomerular chemokine expression. The different changes in glomerular expression of MCP-1 and MIP-1alpha in patients with LN-CGN and V-CGN after pulse therapy may correlate to different responses to treatment and prognosis.

Advances in understanding of idiopathic pulmonary fibrosis

Our understanding of idiopathic pulmonary fibrosis （IPF） has undergone major changes in recent years. IPF is the most common of the idiopathic interstitial pneumonias. It remains the most often diagnosed, accounting for 50% to 60% of all cases. It is also associated with a worse prognosis than most of the interstitial lung diseases. The number of deaths related to IPF is nearly 14 times greater than those from asbestosis, while a recent estimate has suggested prevalence in the United States ranging from 14.0 to 42.7 cases per 100 000 population, depending on the criteria used for diagnosis,

Multi-organ protection during open heart surgery

PURPOSE AND METHODS: Open-heart surgery with the use of cardiopulmonary bypass (CPB) is associated with an inflammatory cascade which contributes to the development of postoperative complications including multiple organ failure. To provide an update on the subject, we briefly review the recent English-language literature. RESULTS: During CPB, various factors have been recognized to induce a complex inflammatory response. Based on an enhanced understanding of the underlying mechanisms, therapeutic strategies have been developed to reduce this inflammatory reaction and its subsequent damaging effects. Off-pump coronary artery bypass grafting may result in less inflammatory injury as compared with the conventional maneuver, which can in turn, diminish the incidence of cardiac, renal, or neurological dysfunction. It is also clear that improving the biocompatibility of CPB materials can lead to a better patient recovery. Inasmuch as the pathophysiology involved appears to be multifactorial, it is unlikely that a single intervention could achieve the desired goal. Both pharmacologic strategies, such as steroid pretreatment, and modification of mechanical devices, such as the use of heparin-coated CPB circuits, could have important clinical implications. The balance pro- and anti-inflammatory responses may be crucial in limiting the extent of inflammatory injury. CONCLUSIONS: To date, the concept of organ protection should no longer be limited to the individual organ. Instead, investigations must be extended to focus on a systemic level.

Effect of Zhu-yuan decoction in patients with chronic rhinosinusitis after functional endoscopic sinus surgery

OBJECTIVE: To investigate the effectiveness and safety of Zhu-yuan decoction(ZYD) in patients after functional endoscopic sinus surgery(FESS).METHODS: A total of 85 patients were randomized into two groups: 44 were treated with intranasal corticosteroids(INC), and 41 were given Chinese herbal medicine(CHM). Patients with chronic rhinosinusitis(CRS) who underwent FESS were prospectively enrolled in the study. Before surgery, they were evaluated by visual analog scale(VAS), nasal endoscopy, computed tomography(CT), and routine blood test. After surgery, they were randomized to take ZYD or INC for 12 weeks and revaluated by VAS; nasal endoscopy at 4, 8, and 12 weeks;and CT at 12 weeks after surgery.RESULTS: In the both groups, VAS and endoscopyscores decreased significantly at 4, 8, and 12 weeks,and CT scores after treatment declined at 12 weeks compared with baseline scores. No significant differences were observed with regard to postoperative VAS, endoscopy, or CT scores between groups.ZYD, combined with surgery, can reduce VAS, nasal endoscopy, and CT scores and has the same efficacy and safety profile as INC in post-FESS management.No fatalities or major adverse events occurred in either group.CONCLUSION: Our findings suggest that ZYD has similar effects and safety profiles in patients after FESS compared with INC.

Treatment of exfoliative cheilitis with Traditional Chinese Medicine：a systematic review

OBJECTIVE:To systematically review treatments of exfoliative cheilitis based on symptom patterns in terms of Traditional Chinese Medicine.METHODS:Pub Med, Cochrane Central Register of Controlled Trials and Wanfang data were screened for case reports, case series or clinical trials that were published in English or Chinese from January,1973 to September, 2015.The keyword of "exfoliative cheilitis or scaling cheilitis or factitious cheilitis" was used.Effectiveness or ineffectiveness was investigated as outcome for Meta analysis, which is based on effective index in each study.Response to treatment was described for case reports or case series.RESULTS:From 38 screened studies, 17 were randomized controlled trials(RCTs), 5 were single-arm trials, and 16 were case reports or case series.Three RCTs were eligible for Meta analysis and all of them compared managements between Traditional Chinese Medicine and corticosteroids for exfoliative cheilitis, which involved 223 participants.Interestingly, data of Meta analysis showed similar effect of Traditional Chinese Medicine and corticosteroids for patients with exfoliative cheilitis [relative risk ratio:1.10; 95% CI(1.00-1.21), P = 0.06].CONCLUSION:Traditional Chinese Medicine might be a substitute for corticosteroids on exfoliative cheilitis.However, the evidence and recommendation of exfoliative cheilitis managements need to be taken with caution because of the low quality of evidence in the studies obtained.
