Objective To study breathing characteristics of normal children of 6～7 years old when speaking in a normal manner.Methods RM 6240 physiological signal collection and processing system and Hx 100 respiratory transducer were used to collect the average peak expiratory pressure,inspiratory valley pressure,respiratory rate,respiratory depth from 160 normally speaking children.Results When speaking,the average peak expiratory pressure,inspiratory valley pressure,respiratory rate and respiratory depth of chest were all significantly increased (P<0.01);while that of abdomen was all reduced(P<0.05,P<0.01)except for respiratory rate(P<0.05)which was increased.In both respiratory conditions,all the data of abdomen were significantly larger than thaf of chest(P<0.01);all the data of boys were larger than that of girls(P<0.05,P<0.01).Conclusion When speaking,it involves thoraco-abdominal breathing,and the increase of chest activity will increase the volume of inhaled air.The increase of abdominal activity is for better control of respiratory airflow.Abdominal breathing plays a main role in normal speaking.Boys'respiratory muscles,respiratory organs are developed better than girls.

Objective The aim of this study was to evaluate the clinical value and the possibilities of measuring the serum levels of pepsinogen I (PG I ) and careineembryonic antigen (CEA) in 402 patients with gastric ulcer.Methods The patients with gastric ulcer were all confirmed by either operation or gastrofiberscope,and divided into two groups,benign and malignant gastric ulcer.After comparing the relationship between the patients'clinical appearance and the Radioimmunoaasay(RIA) results,(CEA and PG I ).Results There were 73 patients were onfirmed malignant gastric ulee in 402 patients.The positive rate of PG was 52.05% (38/73).The positive rate of CEA was 64.38% (47/73).Both were 30.14% (22/73).Then there were 63(63/73) patients who was positive in the combined determination.Solo determination's positive rate of CEA and PG were significantly different from the combined determination.(P＜0.05 and 0.01) Conclusions Feasibility and the necessity of combined determination were evaluated.Compared with solo determination,for patients with malignant gastric ulcer,it was more sensitive to determine and analysis the serum levels of PG I and CEA sYnthetically.So it is recommended to popularize the combined determination of serum PG I and CEA in clinical distinctive diagnosis of benign and malignant gastric ulcer.

Objective Use McGurk effect paradigm materials to explore the role of lip-Reading for hearing-impaired children in phonetic identification.Methods Thirty-six severe prelingually hearing-impaired children and thirty-six normal healthy children(binaural PTA≤20 dB HL)were recruited in the study.The test material was composed of audio and video,including/ba/,/da/,/bi/,/di/,/bu/,/du/six stimulation sounds which were video recorded as pronounced.Under 3 different conditions,the two groups were evaluated for the accuracy of audi-tory responses.Results The accuracy of auditory responses of hearing-impaired children group was 0.71 ±0.19, 0.96±0.07,0.11 ±0.16 for auditory-only mode,audio -visual consistent mode and audio -visual inconsistent mode,respectively,0.93±0.10,0.96±0.11,0.54±0.23 for normal hearing children in auditory-only mode,audi-o-visual consistent mode and audio-visual inconsistent mode,respectively.Conclusion The Audio-visual con-sistent mode is the best one and the lip-reading can help hearing-impaired children in phonetic identification.

Objective To study the efficacy and safety of reboxetine and citalopram in treating retardant depression.Methods A total of 59 patients with retardant depression were randomly divided into reboxetine group(n=29)and citalopram group(n=30)for the treatment of 6 weeks.The patients were assessed with the Hamilton depression scale(HAMD)and treatment emergent symptom scale(TESS).Results At the end of 6 weeks,the total scores of HAMD in reboxetine(18.48±6.38)group and citalopram(11.60±4.46)group both significantly decreased(P＜0.001).Between two groups,the efficacy(82.8% and 56.7%)had significant differences(P＜0.05)but side effects had no statistical significance.Conclusion Reboxetine has significant curative efficacy,milder adverse effects and higher safety for treating patients with retardant depression.

The ideal molecular imaging probe should have characteristics of specificity,sensitivity and safety.Aptamers are sing-strand DNA or RNA oligonucleotides which can bind their targets with high specificity and high affinity.Aptamers are new types of molecular imaging probe because they have many advantages,such as their large sum of possible targets,small molecule weights,easily production and modification,low immuno-genicity,high tissue penetration and so on.Now more and more aptamers research on tumor molecular imaging provides a new technology and tool for tumor diagnosis and therapy.

Objective To inquire into the relationship between infections of Toxoplasma gondii and apoptosis of spermatogenic cells. Methods Apoptotic spermatogenic cells of mice infected with Toxoplasma gondii were examined by Wright-Giemsa staining and terminal deoxynucleotidyl trans-Icrase (TdT) mediated deoxyuridine triphosphate (dUTP)-biotin nick-end labeling (TUNED techniques. Results Apoptosis rate of infective group of Toxoplasma was significantly higher than thai oi control group (F

Objective To investigate the risk factors to acute lung injury based on multiple trauma to provide a theoretical basis for early intervention .Methods The emergency surgical patients with multiple trauma in our hospital from March 2006 to March 2011 were selected .The patients meeting the diagnostic criteria for acute lung injury were taken as the study group and the others as the control group .All patients were enrolled for evaluating the injury severity score (ISS) ,acute physiology and chronic health Ⅱ(APACHE Ⅱ) score and recording smoking ,alcohol abuse ,diabetes mellitus ,number of organ damage ,gastrointestinal bleeding , pulmonary contusion ,diffuse intravascular coagulation (DIC ) ,vomiting ,traumatic shock ,time to correct shock ,blood transfusion . The polymorphism of rs3788853 ,rs13306087 ,rs12709426 of angiotensin-converting enzyme(ACE) gene were analyzed .Results In the study group and the control group ,there were statistical differences in 6 influencing factors of the ISS ,APACHE Ⅱ score ,blood transfusion ,DIC ,traumatic shock ,time to correct shock>6 h(P<0 .05);the gene and genotype frequencies of ACE between the two groups had no statistical difference (P>0 .05);the 6 kinds of influencing factors were risk to acute lung injury based on multi-ple trauma by Logistic regression analysis .Conclusion The ISS ,APACHE Ⅱ score ,blood transfusion ,DIC ,traumatic shock ,long time to correct shock are the risk factors to acute lung injury based on multiple trauma .

Objective:To explore the effectiveness of comprehensive care and help system to promote the rehabilitation of patients with depression,through the case study of 1 typical college student with depression.Method:Through the establishment of the community network support system:teacher's home visits and talk,professional counseling,love and support from dormitory roommates,classmates and relatives,we provided a three-in-one community comprehensive support system and comprehensively used health education,social support,cognitive therapy and other methods,in order to promote the rehabilitation of patients with depression.Results:Through the systematic and scientific comprehensive care,the patient basically freed from the shadow of depression and put into the clinical practice with a positive attitude.Conclusion:Comprehensive Care Education is possible to promote the rehabilitation of college students with depression.

Preoperative anesthetic interview is not only an important part of clinical teaching,but also a vital tache of improvement for medical treatment quality.Unlike internal medicine and surgery,interview for anesthesiology department has its own characteristics.Anesthesiology department of Changzheng hospital has put great emphasis on preoperative anesthetic interview.Some experiences about preoperative anesthetic interview were introduced in our article.

Evidence-based medicine(EBM)is an inevitable development tendency of clinical medicine education in 21 century.Its core thinking is to combine evidence,personal experiences and patients'actual situation.The thinking of EBM will magnificently promote the conversion of conception and model of clinical education and will make significant influence on clinical teaching,scientific research and clinical practice.
