Invasive aspergillosis (IA) is a major cause of morbidity and mortality in immunocompromised children.The purpose of the review was to provide epidemiological,clinical aspects,diagnosis and antifungal treatment options in the pediatric population.Diagnosis of IA remains a challenge as the clinical and imaging manifestations are not specific,and a histological diagnosis is often unfeasible,and blood culture shows low sensitivity rates.In recent years,great progress has been made in the detection of fungal biomarkers,which is mainly described in this paper.

Objective To observe the effects of hyperbaric oxggenation (HBO) on liver blood flow, hepatic functions and the changes of clinical manifestations in patients with chronic hepatitis. Methods Thirty two patients with chronic hepatitis (HBO group) were treated with HBOThe changes of blood flow of the right branch of portal veinin HBO group were and hepatic functions were measured. Results After HBO, hepatic functions were significantly improved, and the blood flow of the right branch of portal veinwas was increased as compared with that before the treatment(0.318?0.101 L/min vs 0.378?0.102 L/min, P

Objective To explore the clinical effect of refractory atelectasis treated with high dose ambroxol.Methods 112 patients with refractory atelectasis were selected as research subjects.All the patients were divided into two groups with each group 56 patients according to admission order.The control group received symptom treatment,physics treatment and routine dosage ambroxol,while the observation group received high dose ambroxol.The clinical effect and safe between two groups were compared.Results The excellence rate and total effective rate of the observation group were 71.43％ (40/56) and 100.00％ (56/56),respectively,which were higher than 51.79％ (29/56) and 83.93％ (47/56) of the control group (x2 =4.57,9.79,all P ＜ 0.05).There were no statistical difference on the total adverse effect incidence rates between the two groups(x2 =0.15,P ＞0.05).No other sever adverse effects happened in both groups.Conclusion Compared with routine dosage ambroxol,the clinical effect of refractory atelectasis treated with high dose ambroxol was better.The treatment was also safe.It was worth generalizing on the treatment of refractory atelectasis.

ObjectiveTo obtain data related to various periods of acupuncture treatment for rat focal ischemia and reperfusion and infer the optimal time point of acupuncture treatment by examining cerebral ROCK expression on the ischemic side in different periods of acupuncture for rats with focal ischemia and reperfusion.MethodOne hundred andeighty male adult Wistar rats were enrolled and randomly allocated to blank, sham operation, model and acupuncture groups. The model and acupuncture groups were separately divided into 5 subgroups: the 6 h, 24 h, 48 h, 72 h and 2 w subgroups. There were atotal of 12 groups, 15 rats each. An animal model of focal cerebral ischemia was made using a thread occlusion method for obstructing rat right middle cerebral artery. The carotid artery was only separated in the sham operation. Materials were taken in the blank and sham operation groups on day 2 after model making. Materials were taken for examination in every subgroup of the model group at 6, 24, 48 and 72 hours and 2 weeks after model making. Materials were taken for examination after acupuncture at Baihui(GV20), Dazhui(GV14)and Zusanli (ST36)in every subgroup of the acupuncture group at 6, 24, 48 and 72 hours and 2 weeks after model making.ResultAcupuncture markedly improved neurological deficits in rats with cerebral ischemia and reperfusion. Areduction in the neurological deficit score was largest in the 6 h acupuncture group and there was a statistically significant difference compared with the other acupuncture groups (24 h, 48 h and 72 h) (P<0.05). There was no statistically significant difference in ROCK expression between the sham operation and blank groups (P>0.05). There was a statistically significant difference in ROCK expression between the model (ischemia-reperfusion 6 h, 24 h, 48 h and 72 h) and blank groups (P<0.05). ROCK expressionreached the peak value at 6 hours after ischemia and reperfusion. There was a statistically significant point-to-point difference in ROCK expression between the acupuncture (ischemia-reperfusion 6 h, 24 h, 48 h and 72 h) and model (ischemia-reperfusion 6h, 24 h, 48 h and 72 h) groups (P<0.05). ROCK expression was down-regulated most markedly in the ischemia-reperfusion 6 h acupuncture group.Conclusion Acupuncture has an inhibitory effect on Rho/Rock in a rat model of cerebral ischemia and reperfusion. Six hours after ischemia and reperfusion is the optimal time point of acupuncture treatment. Acupuncture at that time can protect and improve post-ischemic injured brain tissue to the largest extent.

Aquaporins (AQP) are membrane channel proteins which facilitate water transport through cell membranes.AQP4 is abundantly expressed in brain which is located in endfeet of astrocytes adjacent to capillaries,neurons,and neuronal synapses.It has also been identified in neurons of the supraoptic and paraventricular nuclei of the hypothalamus.AQP are closely related to many central nervous system diseases.Researches have showed that AQP4 participates in regulating and controling process of cerebral edema that caused by brain trauma,cerebral ischemia,intracranial infection and mmour,etc.AQP4 antibody is specific biological markers in serum of patients with neuromyelitis,which helps diagnosis of neuromyelitis optica and multiple sclerosis,predicting prognosis and therapy of neuromyelitis optica.AQP4 has been shown to play roles in pathological and physiological process of neurodegenerative diseases,epilepsy,migraine.This article aims to review the distribution,function,influential factors of AQP4 and research development of AQP4 in common diseases of the central nervous system.

“Expert consensus for the diagnosis and management of septic shock( infectious shock) in children (2015)” has been published based on the “Recommended protocol for diagnosis and treatment of septic shock in children” which was published in 2006.The definition, diagnosis and early management pro-t ocol of pediatric septic shock was revised partly in the latest expert consensus.The goal of the expert consen-sus was to guide the clinical physicians on early identification and early intervention of pediatric septic shock, and reduce mortality and improve prognosis of septic shock in children.

OBJECTIVE:To investigate the effects of ligustrazine combined with N-acetylcysteine (NAC) on the peripheral pro-inflammatory cytokines and intestinal microflora of chronic stress rat. METHODS:Normal rats were included in normal control group,and chronic stress model rats were divided into model group,NAC group (60 mg/kg) and ligustrazine+NAC group (15 mg/kg+60 mg/kg),with 20 rats in each group. They were given relevant medicine intragastrically for 15 d. The general inspection of rats were recorded in each group. Level of IL-6,IL-1β,TNF-α and INF-γ in serum were detected,and intestinal microflora was measured. RESULTS:Compared with normal control group,chronic stress symptom of rats were found in model group,and level of IL-6,IL-1β,TNF-α and INF-γ in serum were enhanced;Escherichia coli and Enterococcus in intestine were increased,while Bacterium lacticum and Bacillus bifidus were decreased (P<0.05). Compared with model group,chronic stress symptom of rats were relieved in NAC group and ligustrazine+NAC group,and above indexes were all improved (P<0.05);ligustrazine+NAC group was better than NAC group(P<0.05). CONCLUSIONS:Ligustrazine+NAC can improve chronic stress of rats by decreas-ing pro-inflammatory cytokines and improving the intestinal microflora.

OBJECTIVE:To discuss about the spot break for promoting technical skipping in pharmaceutical industry of China.METHODS:Based on imbalance of technical development,matrix of technical change skipping and cluster of innovation,the necessity and possibility of the spot break for promoting technical skipping in pharmaceutical industry of China were discussed.RESULTS & CONCLUSIONS:Because the spot or part break is the normal model for promoting technical skipping in history of technical change and innovation,so if pharmaceutical industry of China wants to get technical skipping,we have to promote the spot break.In the end of this paper,the suggestions how to get spot breaks in the skipping of pharmaceutical technical change and innovation in China are put forward.
