In order to improve the efficacy of vibration expectoration and prevent secondary injury in patients with chest trauma,the body surface marking method was used in vibration expectoration.The exact injured locations and areas were identified via CT ot X-ray results.Then,the restricted and focused areas of expectoration were marked with red and green colors,which could guide the machines to avoid the fracture sites,reduce pain,prevent secondary injury and administrate effective expectoration in the areas of sputum and atelectasis.However,the dynamic CT or X-ray results must be used for reference to ensure the accuracy of the body surface marking.

Objective To describe body mass index (BMI) changes in migrant children with overweight and obesity in Beijing treated by the exercise and dietary intervention programme.Methods BMI was assessed at before and after the intervention in 30 migrant obesity and overweight children aged 9 ～ 12 in two schools from March,2010.Results BMI reduced significantly one week after the intervention ( P ＜ 0.05 ),but from two months to six months after the intervention BMI increased again to the pretreatment level( P ＜ 0.05 ).Conclusion The intervention was successful in decreasing BMI,however maintenance of BMI after treatment was not easy.The controlling of obesity and overweight is a long term process which needs the cooperation and supervision of their parents.

Objective To observe the effects of electrical acupuncture for the treatment of neurogenic detrusor overactivity (DO) caused by spinal cord injury (SCI).Methods Twenty SCI patients with DO were included in this study. There were 18 males and 2 females;age ranged from 17 to 58 years. Patients were given electro-acupuncture treatment at the bilateral S3 foramen at the lateral position during the vidio-urodynamic investigation when the detrusor of the patients began to contract.The different intensities of electrical stimulation were used when the DO appeared during cystometry and the most effective intensity to inhibit DO was determined. Then, the bladder was emptied and the stimulation with selected intensity was used at the beginning of cystometry. The changes of parameters in the urodynamics, the urinary incontinence times per day and the pad used per day were recorded. The acute effects were observed. Ten days were set as one course and after 3 courses and 9 courses the patients underwent urodynamic test again. The long-term effects were observed.Results After treatment, the urinary incontinence times per day and the pad used per day decreased obviously (P<0. 05). The bladder capacity increased significantly and the maximum intravesical pressure decreased significantly. There were 3 patients having the long terms treatment. Conclusions The Chinese electro-acupuncture at S3 foramen in the SCI patients with DO is demonstrated effective. After the treatment bladder capacity could increase and the times of the urinary incontinence per week decrease.

The practice and exploration of bilingual teaching for the course of microbiology has been made in order to improve the students foreign lingual level and to meet the higher requirement on tip-top person with the social development. As a result,bilingual teaching is welcome,and the teaching effect is so distinct that the aim was reached to either study the fundamental knowledge or enhance the English level.

Objective To investigate the effects of different standard cross sections and angles on the measurement accuracy of induced postnatal fetal long bones. Methods Fetal long bones (femori and humeri) in 30 cases with induced abortion were measured utilizing ultrasound from different angles and /or at different directions. The values measured from different sections and angles with vernier calipers were compared prenatally and postnatally. Results There was no apparent difference between the pre-induced abortion and those of the post-induced abortion. The results in the 30 cases showed that: (1) the values measured from anterior 90 degree, the long bone length would best match with the bare long bone length up to 96.7%, the match rate of other angles and/or directions was up to 80%; (2) no apparent statistical difference was between the length of left and right bone and no difference was found using 4 different directions and 3 different angles; (3)there was no difference between the left and right femuri and humeri.Conclusions Though the measured value from anterior 90 degree direction was the most accurate one, the statistical analtical results showed no difference among 12 values measured from 3 different angles and/or 4 different directions.

Objective To summarize the diagnostic and therapeutic experiences for multiple insulinoma. Methods Clinical data of 34 cKsefl of multiple insulinoma treated in Peking Union Medical College Hospital between 1984 and 2007 were analyzed retrospectively. Results Multiple insulinoma was identified in these 34 cases for 37 instances.Malignant insulinoma was found in 2 cases.Three cases suffered from postoperative recurrent multipie tumors.35.3% cases belonged to MEN1;13.5% cases were of insulinoma combined with islet hyperplasia;43.2% cases had 3 or more than 3 insulinomas;Fifteen cases (40.5%)had had a misdiagnosis.45.2%tumors were smaller than 1 cm in diameter:88.9%multiple insulinonla located at the body and tail of the pancreas.Enucleation of multiple tumors was performed for 48.7 percent of cases. Conclusions Most multiple insulinomas were small,it was difficult for preoperative examination to locate all the tumors therefore.Being on the alert against multiple insulinoma and such measures as careful exploration,intraoperative blood glucose determination.fine needle aspiration biopsy,frozen sections helps to avoid missing multiple imuhnoma.

Objective To summarize the ultrasonographic features and differential diagnosis of uterine cornual pregnancy.Methods Trans-abdominal and trans-vaginal ultrasound were performed in 93 uterine cornual pregnancy patients before surgery,ultrasonographic findings of uterine cornual pregnancy through different two approaches were analyzed and compared with surgical and pathologic findings.ResultsIn contrast with surgical and pathological diagnosis,66 cases(82.5%,66/80) of uterine cornual pregnancy were accurately diagnosed by ultrasonography before surgery,these cases were divided into gestational sac pattern (55 cases) and mixed mass pattern(11 cases); 11 cases were misdiagnosed as interstitial tubal pregnancy,2 cases were misdiagnosed as pregnancy in rudimentary horn,1 case was misdiagnosed as choriocarcinoma,misdiagnosed rate were 17.5%(14/80); uterine cornual pregnancy presented as adnexal mass in ultrasound in 13 cases,while ruptured uterine cornual mass were found in surgery,in which location and type of the masses couldn't be accurately diagnosed by ultrasound.Ultrasonographic features of uterine cornual pregnancy presented as a gestational sac located in extended cornual of uterus,surrounded by thin myometrium,and connected with endometrium.The misdiagnosed causes were: (1) Uterine cornual mass was not connected with endometrium or surrounded by thin myometrium,which were misdiagnosed as interstitial tubal pregnancy.(2) Uterine cornual pregnancy with thick lateral myometrium were misdiagnosed as pregnancy in rudimentary horn.(3)Uterine cornual pregnancy presented as cornual mass with abundant blood flow was misdiagnosed as choriocarcinoma.Conclusions Uterine cornual pregnancy can be accurately diagnosed by trans-abdominal and trans-vaginal ultrasound.Ultrasonographic features are helpful in differential diagnosis of uterine cornual pregnancy.

Objective:To explore the experience and inner feeling of self-nutrition management in patients with nasopharyngeal carcinoma undergoing radiotherapy and chemotherapy based on health action process approach (HAPA) model as the theoretical foundation.Methods:This study was a qualitative sutdy. Using the purposive sampling method, the semi-structured interview was conducted on 15 nasopharyngeal carcinoma patients with radiotherapy and chemotherapy in Department of Tumor Center Area 2 in the Second Affiliated Hospital of University of South China. Colaizzi 7-step analysis method was used to analyze the original data.Results:According to the two stages of HAPA model, three themes were extracted, namely, positive cognition of self-nutrition management, difficulty in self-nutrition management and lack of self-nutrition management ability.Conclusions:Medical staff should analyze individual differences among patients, understand their subjective feelings, confusion and needs for self nutrition management, provide personalized nutrition education and support, improve their self nutrition management experience and enhance their self nutrition management abilities.

OBJECTIVETo evaluate the clinical characteristics and risk factors of clonal evolution after immunosuppressive therapy (IST) in children with severe/very severe aplastic anemia (SAA/VSAA).

METHODSThe clinical data of 231 children with newly-diagnosed SAA/VSAA who received IST were retrospectively studied. The incidence and risk factors of clonal evolution after IST were analyzed.

RESULTSThe 5-year overall survival rate of the 231 patients was 82.7%. Except for 18 cases of early deaths, 213 patients were evaluated for IST efficacy. Among the 231 patients, cytogenetic abnormalities for at least two chromosome metaphase were detectable in 14 (7.4%) patients, and PNH clones were detectable in either peripheral red blood cells or neutrophils for 95 patients. Among the 213 patients evaluated for IST efficacy, 15 patients experienced clonal evolution after IST. Five patients had PNH and trisomy 8 which were defined as favorable progressions, and ten patients experienced monosomy 7 and MDS/AML as unfavorable progressions. The 5-year accumulative incidence of favorable and unfavorable progression were (2.2±2.2)% and (4.8±3.3)%, respectively. Until the last follow-up, 100% (5/5) of patients with favorable progressions and 50% (5/10) of patients with unfavorable progressions survived. WBC>3.5×10/L, CD3T cell percentage>80%, dosage of antithymocyte globulin >3.0 mg/(kg·d) and no response to IST were related to unfavorable progressions by univariate analysis. Cox multivariate analysis revealed that an increased CD3T cell percentage (>80%) and no response to IST were independent risk factors for unfavorable progressions.

CONCLUSIONSThe children with SAA/VSAA who have an increased CD3T cell percentage at diagnosis or have no response to IST are in high risks of unfavorable progressions.
