A consensus on the management of allergy in kindergartens and primary schools / 中国学校卫生

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Inhibitory Effects and Mechanisms of Three Benzodiazepines on Helicobacter pylori / 中国医学科学院学报

Objective To explore the inhibitory effects and mechanisms of benzodiazepines on Helicobacter pylori (Hp).Methods The Hp international standard strain ATCC43504 was treated with benzodiazepines diazepam,midazolam,and remimazolam,respectively.The treatments with amoxicillin and clarithromycin were taken as the positive controls,and that with water for injection as the negative control.The inhibition zone of each drug was measured by the disk diffusion method.The minimum inhibitory concentration(MIC)and minimum bactericidal concentration(MBC)of each drug against Hp were determined.Hp suspension was configured and treated with diazepam and midazolam,respectively.The bacterial suspension without drug added was used as the control group.The concentration of K+ in each bacterial suspension was measured by an automatic biochemical analyzer before drug intervention(T0)and 1(T1),2(T2),3(T3),4(T4),5(T5),6(T6),and 7 h(T7)after intervention.Hp urease was extracted and treated with 1/2 MIC diazepam,1 MIC diazepam,2 MIC diazepam,1/2 MIC midazolam,1 MIC midazolam,2 MIC midazolam,1 mg/ml acetohydroxamic acid,and water for injection,respectively.The time required for the rise from pH 6.8 to pH 7.7 in each group was determined by the phenol red coloring method.Results The inhibition zones of diazepam,midazolam,remimazolam,amoxicillin,clarithromycin,and water for injection against Hp were 52.3,42.7,6.0,72.3,60.8,and 6.0 mm,respectively.Diazepam and midazolam showed the MIC of 12.5 μg/ml and 25.0 μg/ml and the MBC of 25 μg/ml and 50 μg/ml,respectively,to Hp.The concentrations of K+ in the diazepam,midazolam,and control groups increased during T1-T7 compared with those at T0(all P<0.01).The concentration of K+ in diazepam and midazolam groups during T1-T4 was higher than that in the control group(all P<0.01).The time of inhibiting urease activity in the 1/2 MIC diazepam,1 MIC diazepam,2 MIC diazepam,1/2 MIC midazolam,1 MIC midazolam,and 2 MIC midazolam groups was(39.86±5.11),(36.52±6.65),(38.58±4.83),(39.25±6.19),(36.36±4.61),and(35.81±6.18)min,respectively,which were shorter than that in the acetohydroxamic acid group(all P<0.01)and had no significance differences from that in the water for injection group(all P>0.05).Conclusion Diazepam and midazolam exerted inhibitory effects on Hp,which may be related to the cleavage of Hp cells rather than inhibiting urease.

Expression and significance of VEGF and p53 in degenerate intervertebral disc tissue

OBJECTIVE@#To investigate the mechanism of expression and significance of vascular endothelial growth factor (VEGF) and p53 in degenerate intervertebral disc tissue.@*METHODS@#Pathological sections collected from 156 patients with lumbar disc herniation after surgery were tested by immunohistochemistry method, for evaluation of the expression of VEGF and p53 in degenerate intervertebral disc tissue.@*RESULTS@#98 cases (62.8%) with vascular infiltration phenomenon are found, and positive rates of VEGF and p53 in degenerate intervertebral disc tissue are 73.42% (116/156) and 58.97% (92/156); co-expression rate is 53.2%(83/156); the expression rates of VEFG and p53 are significantly higher in the tissue with blood vessel infiltration than in the tissue without infiltration; there is a close relationship of VEGF with p53.@*CONCLUSIONS@#VEGF and p53 gene synergetic express in degenerate intervertebral disc tissue, working together in neovascularization and infiltration, and accelerating intervertebral disc tissue degeneration.

Therapeutic effect of electroacupuncture on chronic orchialgia / 中国针灸

<p><b>OBJECTIVE</b>To compare the efficiency difference in chronic orchialgia between electroacupuncture and western medicine and explore the better therapy for chronic orchialgia.</p><p><b>METHODS</b>Eighty-six cases of chronic orchialgia were randomly divided into an electroacupuncture group (56 cases) and an Indomethacin group (30 cases). Except the conventional oral administration of Amitriptyline for anti-depression, electroacupuncture was applied at Shenshu (BL 23), Ciliao (BL 32), Sanyinjiao (SP 6), Taichong (LR 3) and others in electroacupuncture group, and Indometacin suppository anal therapy was used in Indometacin group. The session of treatment in two groups was 2 weeks. Before and after treatment, pain number assessment scale was adopted for the assessment of pain severity separately to compare the differences in pain score on 3rd, 7th, 10th and 14th days after treatment.</p><p><b>RESULTS</b>The pain score at each time point was improved remarkably as compared with that before treatment in two groups (P < 0.05, P < 0.01). In comparison on the 7th, 10th and 14th days of two groups, the pain scores in electroacupuncture group was lower than those in Indometacin group (all P < 0.05).</p><p><b>CONCLUSION</b>Electroacupuncture combined with Amitriptyline treatment is quite effective on chronic orchialgia, which is superior to the effect of Indo methacin combined with Amitriptyline treatment and deserves to be promoted in application.</p>
