Objective To evaluate the prophylactic effect of abdominal breathing exercises on radiation pneumonitis in patients with chest malignant tumors.Methods 100 patients with chest malignant tumors were given radiotherapy and divided with random digit table into the exercise group and the control group with 50 patients in each group.The incidence rate of radiation pneumonitis in both groups was compared.The prophylactic effect of abdominal breathing exercises on radiation pneumonitis was evaluated.Results The incidence of radiation pneumonitis in abdominal breathing exercise group was significantly reduced [34％ (17/50) vs.56％ (28/50),Z=2.397,P＜0.05],the incidences of grade Ⅰ [22％ (11/50) vs.30％ (15/50)] and grade Ⅱ [12％ (6/50) vs.18％ (9/50)] radiation pneumonitis decreased,and no grade Ⅲ and Ⅳ radiation pneumonitis occurred.Conclusions The incidence of radiation pneumonitis in patients with chest malignant tumors treated with radiation therapy may be decreased by abdominal breathing exercises,which may be widely applied in patients treated with radiation therapy.

AIM　To study the effects of Aβ25～35 and Apo E4 on neuronal intracellular free Ca2+(［Ca2+］i). METHODS　Hippocampal and cortical neurons suspension of newborn(0～3 days) SD rats was produced. After incubated with fura-2/AM,the neurons suspension was divided into four groups: control, Aβ25～35, Apo E4, Aβ25～35+Apo E4. Each groups ［Ca2+］i was measured using a RF-5000 dual wavelength spectrofluorometer after incubated with double distilled water, Aβ25～35, Apo E4, Aβ25～35+Apo E4 for 3 min, respectively. The neurons outocorrelation function(ACF) of the scattering light intersity was analyzed by the microscope quasi-elastic light scattering(MQLS) technique The frequency shift line width by ACF. The Γ can sympolize the cell menbrane flilidity. RESULTS　Both Aβ25～35 and Apo E4 could significantly enhance hippocampal and cortical neurons rest ［Ca2+］i, furthermore, the effect of 5 μmol*L-1 Aβ25～35 was higher than the effect of 1 μmol*L-1 Aβ25～35 (P<0.05), and they also amplified KCl-induced rise in ［Ca2+］i in hippocampal and cortical neurons(P<0.05). The interaction of Aβ25～35 and Apo E4 could also significantly enhance hippocampal and cortical neurons rest ［Ca2+］i andamplified KCl-induced rise in ［Ca2+］i in hippocampal and cortical neurons(P<0.05), but they had no synergic or additive effect.The frequency shift line widith Γ of both hippocampal and cortical neurons were decreased by both Aβ25-35 and ApoE4. CONCLUSION　Aβ25～35 and Apo E4 could enhance neuronal intracellular free Ca2+, amd decrease meirpma; ,e,brame f;iodotu. But their interaction had no synergic or additive effect. It suggested that the amplified effect of Aβ25～35 and Apo E4 on neuronal ［Ca2+］i and membane fluidity may be relative to their neurotoxity.

A reusable chronocoulometric adenosine triphosphate (ATP)-aptamer sensor was developed in this work.A short chain of DNA marked as cDNA containing complementary sequence was immobilized on gold electrode based on Au-S self-assembly.The ATP aptamer was hybridized with cDNA.The surface-confined DNA could bind with [Ru(NH3)63+ (RuHex) in the electrolyte via electrostatic interaction.Upon target ATP binding, the aptamer confined onto electrode surface was disassociated from the cDNA oligonucleotides into the solution.Such surface density change of DNA lead to the decrease of chronocoulometric signal for the RuHex which confined on the electrode surface.The chronocoulometric signals showed a linear relationship with logrithm of ATP concentration in the range of 1 nmol/L to 100 μmol/L, and the detection limit of this aptamer sensor could reach 0.5 nmol/L (S/N=3).This aptamer sensor could be regenerated 5 times by simple steps.With this aptamer sensor, the basal level of ATP in the brain cortex micorodialysate was determined to be 19.2±3.7 nmol/L (n=3).

On the basis of educational psychology fundamentals and characteristics, this study constructed the experiential teaching of music therapy. The preparations made before class include the construction of experiential teaching system, improvement of multimedia resources, and the establish-ment of music therapeutic room. Music therapy activities were taken as the main body and problem-based learning as the leading factor, clinical observation as the basis, and social practice as the com-plement, etc. This study provides basis and reference for the theoretical teaching and clinical practice of music therapy in medical colleges and universities.

OBJECTIVETo explore an effective acupotomology surgery program in treating cubital tunnel syndrome.

METHODSAccording to pathogenic factors and elbow anatomy, a "two points" acupotomology surgery program was designed, which could loose the attachment point of arcuate ligament on medial border of olecroanon and medial epicondyle of humerus. Twenty-one cases of cubital tunnel syndrome were treated with acupotmology, then the efficacy was obsered.

RESULTSAfter one year postoperative visit, 21 patients with ulnar nerve area skin numbness were cured, claw hand deformity and medial hand muscle atrophy recovered significantly. Results of function evaluation were excellent in 17 cases, good in 2 cases, fair in 2 cases and poor in 0 cases, the good rate was 90.5%.

CONCLUSIONThe acupotomology surgery program which could cut the starting and ending points of osborne's ligament and solve the problem of ulnar nerve entrapment is an easy, little-traumatic and effective minimally invasive surgery which also conforms to the anatomical structure.

Objective To explore the relationship of acute infections of Epstein-Barr virus and hydrops fetalis and explore the harm to fetuses and the affection on pregnancy outcomes caused by acute EBV infection during pregnancy. Methods 40 cases hydrops fetalis were diagnosed by ultrasonography. The difference between the EBEA-IgM positive and negative patients blood were studied. 101 cases over the same period of pregnant women with normal fetuses were enrolled as a control group. Results The positive rate of EBEA-IgM in pregnant women (95%) was significantly higher than that of control group(48.5%,P＜0.01). And the differences of the ratio of still birth and live birth and abnormal fetuses induction of labor between the groups were statistically significant（P＜0.01）. Premature birth among the live birth (40%) was obviously higher than that of control group (10.9%,P＜0.05). Conclusions Active infection of EBV in pregnancy was relevant to the hydrops fetalis and there need to pay attention to the detection of EBV during pregnancy.

Objective:To explore the association between the CYP21A2 genotype and the virilization severity in girls with classic 21-hydroxylase deficiency (21-OHD), so as to further the understanding of virilization in females and provide guidance for prenatal diagnosis and genetic counseling. Methods:A total of 23 patients with two X chromosomes (46, XX) who were newly diagnosed with classic 21-OHD in Wuhan Children′s Hospital from August 2010 to March 2019 were included.These patients were divided into 3 groups according to the Prader grades of the degree of external genitalia masculinization.The 17-hydroxyprogesterone (17-OHP) level, androstenedione (AND) level, testosterone (T) level, dehydroepiandrosterone sulphate (DHEAS) level and genotypes were recorded.The gene mutations were divided into the Null group(the enzyme activity was completely impaired), group A(1% of the normal enzyme activity was retained), group B(2% of the normal enzyme activity was retained) and group C(20%-60% of the normal enzyme activity was retained). The correlation between the gene variation of different Prader grades and the corresponding gene groups were analyzed.Results:All 23 girls showed different degrees of external genitalia masculi-nization.There was a significant positive correlation between the Prader grades and the type of gene variation ( rs=0.696, P<0.001). The gene group A and Null group were highly matched with the Prader Ⅳ(the matching rate: 77.8%). Eighty percent of girls with Prader Ⅱ and Prader Ⅲ were classified as the gene group B. The testosterone le-vel of girls with Prader Ⅳ at first diagnosis was significantly higher than that of girls with Prader Ⅱ [4.6(4.0, 15.0)μg/L vs.0.63(0.40, 1.39)μg/L]( χ2=15.117, P<0.05). Conclusions:There is a significantly positive and strong correlation between the degree of external genitalia masculinization and the degree of deficiency of enzyme activity caused by gene variation in girls with typical 21-OHD.It can provide reference for both parents carrying CYP21A2 gene in prenatal diagnosis, genetic counseling and individualized diagnosis and treatment.
