Objective To investigate the effects of Lactobacillus acidophilus tablets combined with infantile diarrhea paste in the treatment of acute diarrhea in children.Methods Retrospective study of a total of 92 children with acute diarrhea from our hospital were collected and randomly divided into experimental group and control group with 46 cases in each group.Patients in the control group were treated by conventional treatment, patients in the experimental group were treated by Lactobacillus acidophilus tablets combined with infantile diarrhea paste.The serum myocardial enzyme, isozyme, inflammatory factors and the levels of T lymphocyte were determined, and the clinical efficacy before and after treatment was compared.Results The clinical effective rate of the control group ( 82.61%) was lower than the experimental group ( 95.65%) , with statistical significance ( P<0.05 );compared with the control group, after treatment the serum myocardial enzyme and isozyme of the experimental group decreased, after treatment the serum TNF-α, IL -6 and I -10 levels decreased, after treatment the CD3 +, CD4 + and CD4 +/CD8 +levels increased, CD8 + level decreased, with statistical significance ( P<0.05 ) , There was no adverse reactions such as gastrointestinal discomfort and skin irritation happened in two groups of patients.Conclusion Lactobacillus acidophilus tablets combined with infantile diarrhea paste in the treatment of children with acute diarrhea could reduce serum myocardial enzymes and isozyme levels, improve immune ability and the effect is remarkable.

Objective To study psychological change on anxiety patients with coronary heart disease (CHD) after percutaneous coronary intervention and to explore the effect of psychological intervention on anxiety patients with CHD.Methods The selected 126 anxiety patients with CHD were randomly divided into three groups A,B,C,and 42 cases in each group.Group A of was the control group,group B was the anti-anxiety drug group,group C was the psychological intervention combinded with anti-anxiety drug,and all patients were treated for one month.The self-rating anxiety scale (SAS) scores were recorded in three groups before surgery,after one week and one month treatment.Resluts There was no significant difference in SAS scores in group A before the operation and after 1 week,1 month treatment(respectively(57.14 ±5.63),(55.86 ±5,46),(53.93 ±6.03),P＞ 0.05).After 1 week and 1 month treatment,the SAS score of group C (respectively (42.79 ± 5.82) points,(33.86 ± 5.05) points) and the SAS score of group B (respectively (49.93 ± 6.63) points,(40.93 ± 6.46)points) were lower than those of group A (respectively (55.86 ± 5.46) points,(53.93 ± 6.03) points),and there were significant differences among the three groups(P ＜ 0.05).Conclusion There is no significantly improvement in patient's anxiety after coronary revascularization.Anti-anxiety drug and psychological intervention significantly improve the patient's negative emotions and reduce the incidence of angina.

Objective To observe the effects of restrain stress on the phosphorylation of p38 mitogen-activated protein kinase ~MAPK) in rat hypothalamus and the regulation effects of electroacupuncture on the phosphorylated-p38 MAPK. Methods Twenty-eight rats were randomly divided into a control group, a restrain stress group and a restrain stress plus electroacupuncture group. The Western blot was employed to observe the changes of phosphorylated-p38MAPK in the three groups. Results Western blot analysis demonstrated a higher level of phosphorylation of p38 MAPK in the hypothalamus from restrain stress group than that from control. The higher level of phosphorylated-p38 MAPK could last for 3 hours after stress was relieved. The level of phosphorylated-p38MAPK could be decreased to some extent when the Zusanli acupoint of the restrained rat was acupunctured. The effects of electroacupuncture of Zusanli on phosphorylated-p38MAPK in hypothalamus could still be retained although the electroacupuncture was ended for 3 hours. Conclusion The results suggested that restrain stress can lead to a higher level of phosphorylation of p38 MAPK in hypothalamus, which might be an important event in the response of hypothalamic-pitutary-adrenal ~HPA) axis. The mechanism underlying the regulation of HPA by electroacupuncture might be (related) to the regulation of phosphorylated-p38 MAPK in hypothalamus.

Objective To study the positions,features and sectional anatomy of the palatovaginal canal and vomerovaginal canal,comparing with CT and MRI findings. Methods The palatovaginal canals in 104 sides and vomerovaginal canals in 60 sides of dry skulls were observed.Three adult cephalic specimens were sliced into celloidin contiguous sections on coronal plane(0.5 mm in thickness) and the results were correlated with the CT studies of 11 patients and MR imaging of a cephalic specimen. Results In dry skulls,the palatovaginal canal displayed as complete canal in 79.8% of the cases,while appeared as groof in 15.4%.There was neither significant canal nor groof in 4.8%.The vomerovaginal canal demonstrated as complete canal in 36.7% of the speciments,while appeared as groof in 33.3%.This canal was communicated with the lateral palatovaginal canal in 15% and it was not detected in 15%.Four typical slices of the celloidin and 3 plane of CT and 3 plane of MRI were selected and the key structures were described.Conclusion The palatovaginal canal and vomerovaginal canal can be well depicted on coronal plane.
