Objective To explore the influence of uncertainty in illness in compliance of respiratory function exer-cise and rehabilitation after surgery in patients with coronary artery bypass graft (CABG) surgery. Methods Mishel uncer-tainty in illness scale and compliance of respiratory function exercise scale were used to collect data in 108 patients with CABG. The correlation of the uncertainty in illness and compliance of respiratory function exercise was analyzed. Patients were divided into three groups (high score, medium score and low score groups) according to the detection of uncertainty in illness. Values of compliance of respiratory function exercise, postoperative care time, postoperative ventilation time, postop-erative hospital stay duration, 6-min walking test (6MWD) and left ventricular ejection fraction (LVEF) were compared be-tween three groups. Results The uncertainty in illness was in medium level (95.51±9.48) in patients with CABG surgery, which was negatively correlated with compliance of respiratory function exercise (r=-0.926, P<0.01). The postoperative venti-lation time and postoperative care time were less in low score group than those of medium score group and high score group. The compliance of respiratory function exercise, 6-min walking test and postoperative LVEF were better in low score group than those of medium score group and high score group. Conclusion Medical personnel should take targeted interventions to reduce the uncertainty in illness in patients, enhance the compliance of respiratory function exercise, reduce the postopera-tive complications and promote early recovery of patients.

Health appropriate technologies are applied nationwide in our country and have produced good results. But the informatization of health appropriate technologies lags behind and is still at a preliminary stage.As the network of Zhejiang basic health appropriate technologies has been estabished,this paper discusses some issues related with the informatization of health appropriate technologies.

Objective To investigate the relationship between apoptcsis, expressions of VEGF and clinicopathological characteris- tics, and prognosis in esophageal squamous cell carcinoma (ESCC). Methods Sixty-one surgical specimens of primary esophageal squa- mous cell carcinomas were examined for VEGF by immunohistochemical staining (S-P). Apoptcsis was determined by TUNEL (TdT media- ting dUTP-biotin nick end-labeling) method. Clinicopathologic features were examined by histopathology. The prognostic impacts of these pa- rameters were analyzed by univariate and survival analysis. Results AI and VEGF were well correlated with differentiation, TNM stage. Lower tumor differentiation and higher TNM stage were related to decreasing AI and VEGF. In addition, VEGF in the groups of invasion be- yond muscularis and lymph node metastasis is significant higher than that in invasion reaching muacularis and no lymph node metastasis (P <0.01). But there were no significant correlation between AI and invasion( P>0.05). The simple-factor analysis results showed that the decrease of AI, VEGF, lymph node metastases, lower tumor differentiation, and invasion reaching muscularis were related to decrease of sur- vival rate. However, multivariate Cox analysis demonstrated that only AI and VEGF were the significant prognostic factors. Conclusions Apoptosis and angiagenesis participate in ESCC and promote its growth. VEGF is related to angiogenesis of ESCC. The increase of VEGF may promote invasion and lymph node metastasis. AI and VEGF are significant prognostic factors in ESCC.

Objective: When the region of interest is somewhere in the middle of the volumetric data, it will be occluded by other regions of the volumetric data and will be hard to see in the reconstruction of volume rendering. In order to provide doctor with comprehensive, visual and accurate diagnostic information, fast volume dipping of medical images on GPU is proposed in the paper. Methods: The rapid volume clipping is achieved by combining the dipping algorithm with the fast volume rendering algorithm based on GPU. The technique is based on fast volume tendering of medical images on GPU. It works as follows: The space information of the section plane is sent to the shader. Then compare the position of the volume data sets with the section plane to decide whether the data is clipped or not. Our algorithm is different from the algorithm that clipping based on depth stencil. We can see the result that reconstructed from the data sets that remained from any position as long as the section plane is defined. Results: According to the shape the users defined, our algorithm can decide which parts of the volume have to be clipped. Because of using the general graphics hardware acecleration, the proposed method achieves interactive display rate. Conclusions: The experiment shows that the algorithm is significantly fast and can meet the requirements of real-time interactive rendering on the premise of ensuring imaging quality and can be used in surgery simulation and so on.

Background Retinal hemorrhage in newborns is a common clinical finding,and serious retinal henorrhage resulting in poor prognosis.The factors affecting retinal henorrhage in newborns are unelucidated now.Identifying these factors is helpful for the early prevention and treatment.Objective This study was to explore the underlying maternal,obstetric,and neonatal clinical factors for degree of retinal hemorrhages in healthy full-term newborns.Methods A cross-sectional study was performed in the approval of Ethic Committee of Zhongshan City People's Hospital.A total of 1 311 full-term infants,with gestational age more than 37 weeks and Apgar ≥9 scores were included in this study.Infants with severe systemic diseases or any other eye diseases were excluded.Ocular fundus of the infants were examined with Ret Cam Ⅲ within 4 days of birth and were independently identified by 2 eye doctors.The newborns of retinal hemorrhage were divided into grade Ⅰ,Ⅱ and Ⅲ groups based on Egge criteria,and the infants without retinal hemarrhage served as the normal control group.Maternal,obstetric,neonatal parameters and general factors were analyzed and compared among different groups,and the risk factors that affected the newborns retinal hemorrhage were analyzed by logistic regression analysis.Results Retinal hemorrhage was seen in 28.30％ infants (371/1 311),and 152,116 and 103 infants were identified as grade Ⅰ,Ⅱ and Ⅲ,with the percentage of 11.59％,8.85％ and 7.86％,respectively.Among the factors that examined in the study,cord around fetal neck was the risk factor of aggravation of degree of retinal hemorrhage in newborns (OR =1.308,95％ CI:1.011-1.693,P =0.041).In the mode of delivery,spontaneous vaginal delivery appeared to be the positive factor of the incidence of retinal hemorrhage (OR=0.134,95％ CI:0.132-0.137,P＜0.001),but cesarean section was not a main risk factor.Conclusions Spontaneous vaginal delivery and cord around fetal neck are the potential risk factors for the aggravation of degree of retinal hemorrhage in full-term infants.Accordingly,infants with these risk factors should be paid more attention to prevent the progression of retinal hemorrhage.
