Bronchiolitis is a common respiratory infective disease in children, which is caused by viruses mostly. A view that bronchiolitis is a special pattern of manifestation of asthma is accepted widely. In the past few years, many agents appeared as a inducement from bronchiolitis to asthma, such as family histoty and atopy. At the same time, the life style of infants( feeding patterns,infective frequency ,environment exposure)plays a role in this process. Studying these factors will help doctors to detect people with high risk, and supply treatment earlier.

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 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.

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.

“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 An initial study on the cognition of the relationship between clinical and management staff for the purpose of improvements. Methods Questionnaires were issued to 38 clinical medical staff and 26 hospital management staff, regarding this relationship. Results Consensus is found between the two groups regarding clinical involvement in management, teamwork and exchange, and cognition on the competence and capability of the other party, P>0.05. On the other hand, however,cognitive differences are found regarding mutual penetration, power balance and implementation of policies and systems. Conclusions In-depth cooperation and understanding between the two groups and the mutual conversion of their behaviors and concepts are the cornerstones of an ideal relationship between clinical staff and management staff.

0.05 ), bacterial clearance were 100% and 90%, and adverse reaction rates were 10%(2/20)and 10.53 % ( 2/19 ), respectively. All those adverse reactions were mainly gastrointestinal tract reactions. The abnormality of laboratory inspections associated with trial drugs happened to 4 and 5 patients in two groups. The reactions were mostly light increase of aminotransferase without effect on therapy. CONCLUSION: Gatifloxacin is an antibiotic with large antimicrobial spectrum and can be recommended to treat light to moderate acute lower respiratory tract infections.

BACKGROUND:There is a close relationship between tumor stem cels and tumor occurrence and recurrence, but there are stil some disputes in the presence of tumor stem cels in al tumors.
OBJECTIVE:To investigate the differentiation and culture of tumor stem cels in human primary gastric cancer cels.
METHODS:Primary gastric cancer cels isolated from fresh gastric cancer tissues were stained with hematoxylin-eosin and identified by immunohistochemical detection of carcinoembryonic antigen. The CD44 expression of the cels was detected using immunofluorescence method. Magnetic activated cel sorting was used to isolate CD44+gastric cancer cels that were then seeded subcutaneously behind the armpit of mice. Growth of implanted tumor cels was observed.
RESULTS AND CONCLUSION:Human primary gastric cancer cels were isolated in serum-free medium. Compared with the routine culture group, the number of CD44+cels(P< 0.05)and the tumor volumewere significantly increased in the spheroid culture group. Furthermore, at 90 days after transplantation, the tumor volume of mice in spheroid culture group was significantly higher than that in the routine culture group. These experimental findings indicate that gastric cancer cels with certain tumorigenicity can be successfuly isolated from gastric cancer cels using serum-free culture method and magnetic activated cel sorting method.
