0.05).Histopathological examination showed no pathological change in the brain,liver,kidneys,and spleen of the mice,but reduced spermatogenic cells spermatozoa.The sperm motility was(40.58?7.75)% in the control,(7.40?1.06)% in the experiment group 1(q=16.909,P0.05).No significant difference in the sperm densities was found among the groups.Conclusions Intermediated alternating magnetic field has adverse effects on the reproduction of mice.Testosterone is one of the target organs of electromagnetic radiation.It is sensitive to IF magnetic field(40 kHz,28 mT).Blood,brain,liver,kidney and spleen of mice are not effected by IF alternating magnetic field.

Objective To understand the effect of butylbenzyl phthalate(BBP) on the levels of DNA-protein crosslinks(DPC) in hepatic cells of mice.Methods Twenty-five male Kunming mice were randomly assigned into five groups(n=5).BBP was administered by intraperitoneal injection at doses of 0(control group),125,250,500,1 000 mg/kg respectively for 14 consecutive days.Then the levels of DNA-protein crosslinks were detected.Results DPC coefficient increased with concentration of BBP increasing.Treatments of 500 and 1 000 mg/kg BBP significantly increased the levels of DPC compared with the control group. Conclusion BBP can not cause DPC at low levels(125 mg/kg),but it can cause DPC significantly at high levels(500 and 1000 mg/kg),which may cause serious DNA damages.

The effect of low dose radiation on tumor metastasis in mice was investigated by using the models of B16 melanoma bloodtract pulmonary metastasis and Lewis lung carcinoma. The results were reported as follows: (1) The number of B16 melanoma pulmonary metastatic colonies of the mice pre-received different doses(25,50,75,100mGy) of whole body irradiation were lower than that of unirradiated control group mice (P

Objective To investigate the levels of transformation growth factor-β1 (TGF-β1),vascular endothelial growth factor (VEGF) and insulin growth factor-Ⅰ (IGF-Ⅰ) role in the pathogenesis of serum of patients with combined pulmonary fibrosis and emphysema (CPFE).Methods Recruited 20 patients with CPFE,40 cases with idiopathic pulmonary interstitial fibrosis (IPF) and 40 cases with emphysema who were admitted to our hospital during July 2011 to February 2012.Serum levels of TGF-β1,VEGF and IGF-Ⅰ were detected by ABC-ELISA.Results Serum levels of TGF-β1 and IGF-Ⅰ were significantly higher in patients with CPFE and IPF than these in patients with emphysema (TGF-β1:(160.73 ± 40.62) ng/L vs.(167.35 ± 42.82) ng/L vs.(128.75 ±35.77) ng/L; IGF-Ⅰ:(179.65 ±60.73) ng/L vs.(192.32 ±58.75) ng/L vs.(148.73 ±49.67) ng/L,P ＜ 0.05 or P ＜ 0.01).The IPF group had significantly higher serum level of VEGF than the emphysema group ((506.12 ±82.37) ng/L vs.(437.31 ±62.58) ng/L,P ＜0.01).Serum levels of TGF-β1 and IGF-Ⅰ in CPFE and emphysema groups were positively correlated (r =0.885,0.918 respectively,P ＜ 0.01).Smokers in the CPFE group had significandy lower level of serum VEGF than those who did no smoke ((406.19 ± 66.94) ng/L vs.(482.88 ± 79.91) ng/L,t =-2.287,P =0.035).Conclusion Serum level of VEGF increased significantly in the IPF group,suggesting the participation of VEGF in pulmonary interstitial fibrosis.IGF-Ⅰ involved in the pathogenesis of pulmonary interstitial fibrosis.TGF-β1 and IGF-Ⅰ have a positive linear regressive relationship,which indicates that they may work synergistically in the process of the fibrosis.

Objective To study the multi-slice spiral CT (MSCT) manifestations of septic pulmonary embolism(SPE) in order to get a better understanding of the disease,Methods The MSCT manifestations of 12 patients with septic pulmonary embolism were retrospectively analyzed and compared with chest radiograph.Results Of the 12 patients,Chest radiograph and CT scanning showed multiple peripheral pulmonary nodules in 8 and 12 cases,a feeding vessel sigu(0,9 cases),cavitations(6,10 cases) and wedge-shaped opacities(4,7 cases),focal infiltrates(2,4 cases),air cyst(2,5 cases),pleural lesions (3,6 cases),hilar or mediastinal lymphadenopathy(0,3 cases).Peripheral or subpleural zones were most commonly affected (8,12 cases).CT was more useful in revealing nodules and a feeding vessel sign.Multiplanar reconstructions (MPR),maximum intensity projection (MIP) showed that most of these vessels passed around nodules and wedge-shaped lesions.MPR showed regular nodular margin.Conclusion SPE presents with variable and often nonspecific clinical and radiographic features.MPR and MIP showed the features of nodules and feeding vessels better.The diagnosis is usually suggested by the presence of a predisposing factor,febrile illness,and CT findings of multiple,periphery pulmonary nodules,with orwithout cavitation and a feeding vessel sign.

OBJECTIVETo explore the clinical effects of minor bone anchors and palmaris longus tendon graft in treating chronic mallet fingers deformity.

METHODSFrom January 2008 to June 2013, 26 patients with chronic mallet fingers deformity were treated with minor bone anchors and palmaris longus tendon graft. There were 18 males and 8 females, aged from 18 to 52 years old with an average of (32.0±1.3) years. Among them, 8 cases caused by machine injury, 6 cases by fall injury, 6 cases by sprain from fight, 4 cases by tendon spontaneous rupture, 2 cases by knife trauma. There was no tendon attachment of extensor tendon check in 16 cases, and with 0.3 to 0.5 cm tendon attachment in 10 cases. All patients had the flexion deformity and the disability of dorsiflexion activity. During operation, the distal interphalangeal joint was fixed in 10° to 20° dorsiflexion by a Kirshner wire, the minor bone anchor was used to reconstruct the extensor tendon insertion, the palmaris longus tendon slice was transplanted the decayed area of extensor tendon insertion. Four weeks postoperatively, the Kirshner wire was removed and the plaster external fixation was used, and the patient began function exercises. Postoperative complications were observed and fingers functions were assessed according to Dargan standard.

RESULTSThe patients were followed up from 6 to 14 months with an average of (5.0±0.3) months. Wound superficial infection occurred in 2 cases, the skin pressure ulcer in 2 cases, joint activities disability in 1 case; these symptoms got improvement after symptomatic treatment. Traumatic arthritis occurred in 2 cases, 1 case was improved after treatment, and 1 case had chronic pain for a long time. No internal fixation loosening or breakage and tendon rupture were found. According to Dargan standard to evaluate the finger function, 17 cases got excellent results, 8 good, and 1 poor.

CONCLUSIONIt is an effective way to treat the chronic mallet finger deformity using minor bone anchors and palmaris longus tendon graft, and the method has advantages of reliable fixation, easy operation, satisfactory effect and less complication.

Objective To evaluate the effectiveness of preoperative perfusion chemotherapy via left gastric artery catheterization in patients with cardiac cancer of the stomach.Methods 56 operated cases with cardiac cancer,who had undergone preoperative perfusion chemotherapy via left gastric artery,were collected and analyzed.Results Most of the tumors were hypervascular as studied with DSA.After perfusion chemotherapy,there was amelioration of symptoms.Decrease in size about 50% of the tumor mass,shown in barium study were found in 32 patients,(18% of them).The survival rates one year,two years and three years after surgical resection were 98%,78.6% and 53.6% respectively.18 cases(32%)had gastric hemorrage,that was the main complication after perfusion.Conclusion Preoperative perfusion chemotherapy via left gastric artery in cases with cardiac cancer of the stomach is an effective measure in increasing resection rates in surgery.

Objective To analyze the flavonoid content of common fruits consumed in China.Method Thirty-eight fruits were sampled from Beijing,Tianjin,Shanghai and Hangzhou.The contents of quercetin,kaempferol,luteolin,myricetin,apigenin were determined with high-performance liquid chromatography.Results Pomegranate and hawthorn were the highest in contents of 5 flavonoids among 38 fruits.Quercetin distributed more widely and was more abundant than other flavonoids in fruits.The daily intake of 5 flavonoids from fruits by Chinese people was estimated to be 2.80 mg.Conclusion The content of flavonoids varies significantly among different fruits and quercetin is the most common flavonoid contained in fruits.
