Three hundred and ninety five patients with bronchial asthma were randomly divided into 4 groups:patients in group A received inhaled beclomethasone dipropionate(BDP)100μg and Zhichuan decoction;patients in group B were given inhaled BDP 200μg;patients in group C took Zhichuan decoction only;patients in group D were given inhaled BDP 100 μg.Methacholine airway reactivity,pulmonary ventilation function,serum acidophilia cationic protein and symptom score were determined before and after treatment.All above indicators were significantly improved in groups A and B,which suggests that Zhichuan decoction could reduce hormone dosage in control of airway chronic inflammation,reduction of airway reactivity and improvement of pulmonary ventilation function of patients with bronchial asthma.

Objective To test the reliability and validity of the brief International Classification of Functioning, Disability and Health (ICF) core sets for Chinese stroke patients using Rasch model analysis. Methods The body functions of 38 Chinese stroke patients were measured using the brief ICF core sets. The qualifiers of the 20items were measured by two raters and analyzed using FACETS statistical software. The intra-rater reliability and validity were tested by using the separation index and separation reliability and fit analysis. Results The brief ICF core sets had good internal consistency and reliability (person separation index = 6.02, person separation reliability = 0.94 ) with these Chinese patients. The raters showed significantly different strictness in rating, but their ratings had good internal self-consistency. The construct validity was good for the body functions of the ICF component ( separation index = 10.50, separation reliability = 0.80) , but misfitting and overfitting were found in items b117, b152and b755. Conclusion The body function of the brief ICF core sets has good reliability and validity for Chinese stroke patients. A many-facet Rasch measurement model can provide comprehensive information and has good application prospects for testing the reliability and validity of ICF core sets.

Objective To review the clinical characteristics of left ventricular pseudo-aneurysm (LVPA) in China mainland.Methods The China National Knowledge Infrastructure (CNKI),Wanfang Data,VIP information and PubMed database were searched to extract information on clinical profile,diagnostic imaging,treatment and outcome of patients with LVPA from January 1986 to April 2012.Results Clinical data of 77 patients with LVPAs (including 5 coexistent with true aneurysm) were extracted from 65 articles.There were 56 males (72.7％) and 11 females (27.3％) with a median age of 48 years old(range 5 to 82).The most common etiology was myocardial infarction (40,51.9％).Breathlessness/dyspnea (44.6％),chest discomfort (41.9％) and chest pain (41.9％) were the most frequently reported symptoms,but asymptomatic patients accounted for 10.8％ of all.86.4％ of the patients had electrocardiographic abnormalities,most of which were nonspecific ST segment changes.No event of thromboembolism was reported.Transthoracic echocardiography was the most commonly used diagnostic imaging test,followed by angiography with which no complication was reported.19 cases of pseudo-aneurysms(24.7％)were reported to rupture and 15 patients(19.5％) died,mostly of cardiac tamponade and sudden death.Conclusions LVPA is a rare and life-threatening disorder.It lacks of specific clinical manifestations distinguishable from coronary disease or heart failure.Emergency surgery is warranted once it is identified.

BACKGROUND:Ultrasound has been widely used in developmental hip dysplasia screening in infants and young children, but there are significant differences among different inspection findings, even in the reexamination by the same examiner. Therefore, the accuracy of ultrasound imaging in the diagnosis is of insufficient evidence.
OBJECTIVE:Through virtual reality three-dimensional reconstruction images showing the structure of acetabulum and femoral head space, to obtain a new parameter in order to enrich measurement standards of Graf ultrasonic diagnosis technology and to further improve the credibility of the diagnosis of developmental dysplasia of the hip.
METHODS:Ten fresh cadaver specimens of Chinese infants were selected, including five males and five females. Two-dimensional ultrasonic method was employed for hip screening, and at the same time, multi-slice spiral CT was used for three-dimensional reconstruction fol owed by volume reconstruction and fitting of surface reconstruction to display the anatomic structure around the hip and to simulate Graf’s two-dimensional ultrasound method to measure a andβangles on three-dimensional virtual reality images.
RESULTS AND CONCLUSION:As confirmed by three-dimensional reconstruction, Graf’s two-dimensional ultrasound could be used to measure a and angles, truly reflecting the development of bony and cartilaginous acetabulum. Graf’s two-dimensional ultrasound contributed to the proper evaluation of beonatal hip dysplasia, which can be used as a routine examination for developmental dysplasia of the hip. These indicate that to master Graf’s ultrasound technology and strictly grasp the evaluation standards for developmental dysplasia of the hip is the important guarantee for diagnosis of developmental dysplasia of the hip.

Objective To synthesize a quantum dot (QD) to recognize glioma cells for imaging and photodynamic therapy. Methods By one-pot aqueous approach, near infrared-emitting CdTe was produced. After detection of its physicochemical characterizations, RGD was conjugated. Emission images were observed with confocal microscopy. To test its toxicity, CdTe-RGD with various concentrations was separately added into U251 and 3T3 cells for incubation in dark circulation. To test its photodynamic effect, U251 and 3T3 cells were then irradiated for 5 ~ 60 min using 632.8 nm laser. Results The QD (Φ = 3.75 nm, PL peak wavelength =700 nm, PLQY=20%) achieved was a spherical crystal with excellent monodispersity. Under confocal microscope , U251 cells were visualized but 3T3 cells not. In dark circulation, the survival rates of both U251 and 3T3 cells were above 85%. After laser irradiation, the survival rate of U251 cells decreased to (37 ± 1.6)%with the increasing of irradiation time and CdTe-RGD concentration. Conclusion With good physicochemical characterization and low toxicity, CdTe-RGD could be applied in biomedical imaging and photodynamic therapy of gliomas.

Objective To observe the appearances of decussation of superior cerebellar peduncle (SCP) on MR diffusion tensor imaging (DTI) with different parameters of scanning and reconstruction. Methods Twenty healthy volunteers were examined on Siemens 3.0T MR DTI (b=0, 1000 s/mm~2), post processing were made in Siemens Leonardo workstation using Siemens Standar 6 dirs software to reconstruct the white matter fibers with different fractional anisotropy (FA) threshold value (0.04-0.20), angle threshold value (20°-89°) and voxel size (1.2 mm×1.2 mm×3.0 mm-1.6 mm×1.6 mm×5.0 mm). Results Crossing fiber was presented each voxel group on diffusion tensor tractography (DTT). The types of crossing fiber in the small voxel were more than those of big voxel image obviously. Reduced along with the FA threshold value, the number of crossing fiber increased gradually. After the peak value (FA=0.08), the number of crossing fiber reduced along with the FA threshold value reduced gradually. Increased along with the angle threshold value, the number of crossing fiber increased gradually. The number of crossing fiber reduced along with the angle threshold value increased gradually after the peak value (the angle threshold value＝80°). There were 5 kinds of MR fiber tracking appearances at the level of decussation of SCP on DTT. The fiber crossed to the opposited red nucleus in anterior-posterior style, superior-inferior style and single main bundle fiber. Kissing fiber and missing fiber sign was shouw in all subjects, which mainly located in the center of the decussation. Conclusion DTT FACT can show the descussation of SCP in most health subjects with five typical appearance. The descussation of SCP has the obvious appearances, may be causing by individual difference. For the crossing fiber of SCP, voxel size 1.2 mm×1.2 mm×3.0 mm, FA 0.08 and the angle 80° are recommended.

Objective To provide basis for the diagnosis,treatment,prevention and control of pertussis by analyzing serological test findings and clinical features of inpatients.Methods Serological test findings (including outpatients and inpatients) of suspected cases and medical records diagnosed as pertussis (severe group and non-severe group) were analyzed in Shandong Provincial Hospital Affiliated to Shandong University from January 1,2012 to December 31,2014.This retrospective study was conducted to explore the epidemiological characteristics,clinical manifestations,image manifestations of pertussis in recent years.Results The incidence of pertussis was obviously higher in 2014 than the previous 2 years,nearly 10 times than that of 2013;summer and autumn were high-occurrence seasons;pertussis was found predominately in children under 6 years old,as 68％-80％,and the majority of them were 3 months-1 year old and 4-6 years old,and there was a notable increase in children more than 6 years old in 2014;the clinical manifestations tended to be atypical,primarily spasmodic cough (79.01％,64/81 cases),cyanosis (60.49 ％,49/81 cases),vomiting after cough (35.80％,30/81 cases),conjunctiva haemorrhage (22.22 ％,18/81 cases) apnea or heart rate decrease(9.88％,8/81 cases),and whooping cough (7.41％,6/81 cases).There were significant differences(all P ＜ 0.05) in age (t =2.940),paroxysmal cyanosis (x2 =4.505),elevated white blood cell count (x2 =4.410),and lymphocyte percentage increase(x2 =7.830) between severe group and non-severe group.There was no statistical difference in sex(x2 =0.847),season (x2 =0.178),spasmodic cough (x2 =0.097),whooping cough (x2 =0.002),conjunctiva hemorrhage (x2 =0.395),apnea (x2 =0.395) and fever (x2 =0.301) between the 2 groups (all P ＞ 0.05).Mixed infection with mycoplasma was most common.Imaging manifestations of pertussis were not specific,and they might manifest uneven density,patchy inflammatory infiltrates and atelectasis.Conclusions The morbidity of pertussis is rising and atypical cases is increasing in these years,and severe cases are seen most frequently in small infants,it is necessary to perfect the laboratory test methods and immunization strategy.

OBJECTIVETo observe the clinical efficacy differences among warming-promotion acupuncture, regular acupuncture and psychological care for post-earthquake depression.

METHODSNinety cases of post-earthquake depression in Gansu province were randomly divided into a warming-promotion acupuncture group, a regular acupuncture group and a care group, 30 cases in each one. The psychological treatment was applied in the care group; the regular acupuncture at Baihui (GV 20), Sishencong (EX-HN 1)), Fengchi (GB 20), Shenmen (HT 7), Yang-lingquan (GB 34), Taichong (LR 3) and Sanyinjiao (SP 6) was used in the regular acupuncture group; based on the treatment of regular acupuncture group, the warming-promotion acupuncture was applied in the warming-promotion acupuncture group, once a day. Ten days were taken as one course with an interval of two days between two courses. Totally 3 treatment courses were completed. The Hamilton depression (HAMD) scale before and after treatment in each group was observed while the efficacy was analyzed.

RESULTSAll three treatments were effective for depression. The total cured rate was 86.67% (26/30) in the warming-promotion acupuncture group, which was obviously superior to 50.00% (15/30) in the regular acupuncture group (P < 0.01) and 33.33% (10/30) in the care group (P < 0.001). After the treatment, the score of HAMD was all reduced in three groups, in which the effect in warming-promotion acupuncture group was superior to that in the regular acupuncture group and care group (9.02 +/- 2.37 vs 10.73 +/- 2.28 and 11.05 +/- 2.01, P < 0.05, P < 0.01).

CONCLUSIONThe warming-promotion acupuncture has positive effect on post-earthquake depression, which has special effect and is worthy of clinical generalization and application.
