Objective To study the inhibitory effects of stachyose on the hyperacute rejection in pig-to-human heart xenotransplantation.Methods A pig-to-human xenogeneic heart transplantation model was established based on an in vitro free heart blood perfusion system.The pig hearts were di- vided into two groups:group A(pig hearts treated with human blood perfusion as control)and group B(pig hearts treated with human blood plus stachyose perfusion).After perfusion for 1h,the heart xenografts were examined for deposit of lgG and IgM by immunohistochemistry and pathological analy sis.Results The mean survival time of perfusion hearts in groups A and B was(9.5?2.5)min and (46.8?8.1)min respectively(P

Objective To study the diagnostic value of endoscopy assisted by laparoscopy in patients with small intestinal bleeding. Methods In case of small intestinal bleeding it is hard to define the accurate etiological factor by routine examination. From 1994 to 2002 there were 14 patients with chronic me-lena or persisted melena complicated with chronic anemia and 2 cases of acute alimentary tract hematorrhea complicated with obvious hypovolemia. Results Endoscopies assisted by laparoscopy were accomplished in all of the 16 cases. Lesions were detected in 5 cases with laparoscopy directly, and in 11 cases the pathological changes were discovered by endoscopies assisted with laparoscopy . The pathologic results were leiomyo-sarcoma 1 cases, leiomyoma 4 cases, adenoma of small intestine , hemangioma , vascular malformation and capillary telangiectasia 2 cases each, and Meckels diverticulitis with hemorrhage 3 cases. Conclusion The diagnostic value of endoscopy assisted with laparoscopy is superior to the routine examination in detecting the small intestinal bleeding. This technique has the advantage of simple, less-traumatic and high sensitivity. It is worthy to popularize in clinical practice.

Objective To evaluate the effect of various herniorraphy in treating inguinal hernia. Methods The clinical data of 108 patients who underwent conventional Bassini herniorraphy (BH), tension free herniorraphy (TH), or laparoscopic herniorraphy (LH),respectively were analysed and comparated. Results The operation time in TH was less than that in BH, and in LH was longer than that in TH. The ability recovery, hospita stay and postoperative complication in TH and LH were less than those in BH.All the patients were followed up for at least 1 year.Of them, 1 recurred after BH, but there was no recurrence after TH and LH. The blood neutrophils, serum level of fibrin, C-reactive protein and alpha-1 antitrypsin increased significantly in the patients undergoing herniorraphy, which were significantly higher in the patients underwent TH and LH. Conclusions The curative effect of TH and LH is much better than that of BH in treating ingumal hernia. Application of marlex for herniorraphy might increase inflammation response, but it will not increase the incidence of infection.

Objective The aim of this study is to evaluate clinical application of BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index in patients with chronic obstructive pulmonary disease (COPD). Methods Forty patients with stable COPD in Xuanwu Hospital of Beijing during September 2003 to December 2007, were recruited in the study, including 25 men and 15 women, aged 38 to 85 years (with a mean of 62 ± 13 years). BODE index was measured for each patient, one year and three years after recruitment, respectively. Severity of COPD, including number and duration of episodes, length of each hospital stay and times of hospitalization due to acute exacerbation of COPD (AECOPD), were recorded. All data were statistically analyzed with SPSS 13.0 software for windows. Results ①There was a remarkable difference in COPD severity between patients with BODE score equal to or greater than five and these with less than five (P <0.01 ). ①BODE score inversely correlated with forced expired volume at the first second ( FEV1 ) in COPD patients (P < 0.01 for those with BODE score equal to or greater than five and P <0.05 for these with BODE score less than five, respectively). ③BODE score positively correlated with number and duration of acute exacerbation, length of hospital stay and times of hospitalization due to AECOPD (P <0. 01 for those with BODE score equal to or greater than five and P < 0. 05 for those with BODE score less than five, respectively). For patients with COPD, their BODE score in the first year positively correlated with that in the third year ( r = 0.834, P < 0.01 ). Conclusions BODE index is a better indicator to evaluate their condition severity in patients with COPD.

Objective To analyze the normal lung dose-volume histogram(DVH) varieties in the former and later period(P1 and P2)of three dimensional conformal radiation therapy(3DCRT) plans and the compound (Pc) plan in non-small cell lung cancer(NSCLC),and to access the feasibility to modify the target volume during the treatment course.Methods Twenty-one NSCLC patients who had received accelerated hyper-frationation 3DCRT in P2 were included in the study.Both of the P1 and P2 plans were redesigned to a total dose of 70 Gy with V20 smaller than 35%.When the target volume was modified and P2 plan was rede signed using accelerated hyper-frationation 3DCRT of 30 Gy after P1 plan of 40 Gy,the Pc plan was compoun ded by transmitting the parameters(such as target volume,irradiation field and dose) of P1 plan into P2 plan. Total lung volume and target volumes(GTV,PTV) of P1 and P2 were evaluated.MLD,V5,V10,V20 and V30 of P1,P2 and Pc were calculated.Results The total lung volume in P1 and P2 plans was not significantly dif ferent(t = 0.19,P = 0.850).The volumes of GTV,PTV in P2 were obviously smaller than P1 (t = 2.88,P = 0.009 ; t = 4.01 ,P = 0.001) .When comparing P2 with P1 ,MLD were 16.5 Gy Vs 17.8 Gy (t = 2.60, DOI:10.3760/cma.j.issn.1004-4221.2009.01.057 P = 0.017),V30 was significantly decreased (t = 2.19,P = 0.041),but V5,V10 and V20 had no significant difference.Similar differences were found in MLD,V5 ,V10 ,V20 and V30 when comparing Po to P1.P2 plans had significantly smaller MLD,Vs,V10,V20 and V30 than Pc plans.Fourteen patients with decreased PTV were further analyzed.The V30 and MLD decreased significantly (t = 3.00,P = 0.0 I 0;t = 2.38,P = 0.033), but V5 ,V10,V20 had no difference when comparing P1 and P2 plans.Among these 14 patients,the V10 and V30 decreased significantly(t = 2.76,P = 0.033 ; t = 3.60,P = 0.011) when P2 plans were generated using the same field number and beam angles in P1 plans in 7 patients.The parameters were similar in P1and Pc plans,but increased significantly when comparing to P2.Various parameters were the same among P1,P2 and Pc plans when P2 plans were designed using 1-2 different fields and angles in the other 7 patients.The differ ences were not significant between P1 and P2 plans in 7 patients with the same or increased PTV.Expansion or contraction of PTV significantly influenced MLD and V2o (r =-0.62,P = 0.03 ; r = O.48,P = 0.029). Conclusions When the tumor regresses,the high dose volume of the lung decreases with modifying the tar get volume and replanning in the later period using accelerated hyper-frationation 3DCRT.The low dose vol ume of the lung may decrease if the field orientations are same throughout the treatment.It is rational to eval uate the normal lung DVH of the whole plan when the physical parameters of the later period plan are the same as the former one.

AIM:To study the visual acuity and refractive status of students pupils and middle school students in Shenzhen, and to provide a scientific basis for the prevention and control of myopia.
METHODS:A cluster sampling method was used to select five primary school students(6 737) and three junior middle school students(1 925) from Shenzhen. The visual acuity, anterior segment, fundus, eye position, and refractive status were measured. Information on associated factors for poor vision were also obtained using a questionaire. The risk factors of poor vision and the rate of myopia between grade or gender were analysed by Chi-square test.
RESULTS:The rate of poor vision was 67. 0%. Female, family history of high myopia, long time of continuous look near, short time of outdoor activities were the main risk factors. The rate of emmetropia, hyperopia, astigmatism and myopia were 15. 1%, 11. 3%, 11. 0% and 62. 6% respectively. Emmetropia, hyperopia and astigmatism incidenece rate decreased with age growing, but myopia incidence rate was increased. There were significant differences between adjacent two grades in myopia(χ2=7. 338-45. 018, P<0. 05 ) except the primary grade six and the junior grade one. There were significant differences between boys ( 61. 0%) and girls ( 65. 5%) in myopia(χ2=17. 180, P<0. 05).
CONCLUSION:The rate of poor vison is pretty high in students of Shenzhen aged between 5 to 16 years old, and myopia is the main reason. The development rate of myopia is increased with age. Early management of myopia may play an important role in controlling poor vision in students.
