Objective:To study the clinical efficacy of acupuncture for ischemic stroke and its effect on ET-1 levels in IS cases.Method:The 63 cases were randomized into a treatment group (31 cases),receiving acupuncture and routine method,and control group (32 cases),receiving routine method alone.Seven days constitute a course of treatment,a 2-day interval between two courses.The clinical efficacy and ET-1 level in two groups were compared after four weeks.Result:The total effective rate in the treatment group and control group were 96.8% and 75% respectively,with a statistical significance (P＜0.05);the ET-1 level in blood plasma also with a statistical significance after the treatment (P＜0.05);the pre-treatment and post-treatment ET-1 level in the treatment group showed a statistical significance (P＜0.01),whereas the control group didn't.Conclusion:Acupuncture is effective for ischemic stroke and can lower the ET-1 level in ischemic stroke cases.

Objective To investigate scanning and reconstruction techniques of multi-slice spiral CT (MSCT) in patients with complex congenital heart diseases (CCHD).Methods One hundred eighty-four patients suffering from CCHD underwent 16-detector MSCT scanning without ECG-gating.Multi-planar reconstruction (MPR),maximum intensity projection (MIP),curved-planar reconstruction (CPR) and volume rendering (VR) were used to reconstruct images.CT findings were compared with those of surgical operation or angiocardiography.Results A total of 616 cardiac deformities were found with MSCT and proved by angiocardiograms or surgical operation.The diagnostic accuracy of extracardiac malformation with MSCT was 100%,of atrial septal defect was 54.65%,and of ventricular septal defect was 78.62%.MSCT failed to display heart valve disease well.Conclusion MSCT can accurately detect extracardiac malformations of CCHD.

Patients with gastrointestinal diseases are more likely to exhibit malnutrition. Nutritional support is needed for those who are with malnutrition or at risk. Nutritional support can be categorized into enteral nutrition and parenteral nutrition. With the widely application of nutritional support,more and more attention has been paid on its role in gastrointestinal diseases. It not only can improve the nutritional status,but also can alleviate the clinical symptoms to some extent and improve prognosis,which makes it a kind of extremely important treatment modality for gastrointestinal diseases. In this article,the advances in study on nutritional support of gastrointestinal diseases were reviewed.

Objective To investigate the risk factors of portal venous thrombosis ( PVST) following laparoscopic splenectomy ( LS) in cirrhotic patients with hypersplenism .Methods The clinical data of 62 patients with secondary hypersplenism due to cirrhotic portal hypertension admitted to the Clinical Medical College of Yangzhou University were retrospectively analyzed .These patients underwent LS from January 2013 to April 2014.Based on whether the patients had PVST on postoperative day (POD) 7 or not, the pa-tients were categorized into the non-PVST and PVST groups .Fifteen perioperative variables were analyzed in these two groups .Results On univariate analysis , age and portal vein diameter in the PVST group were significantly higher and velocity of portal blood flow in the PVST group were significantly lower than those in the non-PVST group, (all P<0.05).Bivariate correlation analysis performed for the relationship between these variables and occurrence of PVST on POD 7 showed age >50 years, portal vein diameter >13 mm and velocity of portal blood flow >18 cm/s were significantly correlated .Multivariate logistic regression showed that age >50 years and portal vein diameter >13 mm were significantly independent risk factors of PVST, and velocity of portal blood flow >18 cm/s was an independent protective factor .Conclusion Age>50 years and portal vein diameter >13 mm were independent risk factors , while velocity of portal blood flow >18 cm/s was an independent protective factor of postoperative PVST .

Objective To investigate the changes in volume and spatial location of target areas and normal tissues before and during intensity?modulated radiotherapy (IMRT) for cervical cancer by quantitative means. Methods Forty patients with cervical cancer who were treated with IMRT were enrolled as subjects. Computed tomography ( CT) was performed before IMRT and during IMRT when a dose of 27 Gy ( 15 fractions) was reached. Clinicians delineated the target areas and organs at risk in the two groups of CT images. The target areas and organs at risk in one group of images were mapped to the other group of CT image by image registration using the Pinnacle treatment planning system. Volume changes in target areas and organs at risk were analyzed, and changes in the spatial location were evaluated by volume difference method and Dice similarity method. Comparison was made by paired t?test. Results There were significant differences in gross target volumes of primary tumor lesions ( GTV?T) and pelvic metastatic lymph nodes (GTV?N) before and during IMRT ( P= 0?? 000; P= 0?? 000). According to the evaluation by volume difference method, the average rate of change in GTV?T was (38.64±19?? 50)% with a range between 3?? 16%and 86?? 49%, while the average rate of change in GTV?N was (42.49± 25?? 68)% with a range between 2?? 79% and 87?? 42%. In the organs at risk, the bladder had the maximum rate of volume change, the average of which was (55.13±33?? 40)% with a range between 3?? 25% and 116?? 01%. According to the evaluation by Dice similarity method, the average Dice similarity coefficient for GTV?T was 0.50± 0?? 18 with a range between 0?? 10 and 0?? 85, while the average Dice similarity coefficient for GTV?N was 0.31±0?? 20 with a range between 0?? 00 and 0?? 71. The rectum had the minimum Dice coefficient in the organs at risk, the average of which was 0.57± 0?? 14 with a range between 0?? 18 and 0?? 76 . Conclusions For patients with cervical cancer to receive IMRT, since there are substantial changes in volume and spatial location of target areas and normal tissues before and during treatment, it is quite necessary to modify the treatment regimen in time in order to provide adequate doses for target areas and avoid overdose for organs at risk.

Fingerprint of traditional Chinese medicine (TCM) is in the guidance of the basic theory of TCM, according to the variety and quality of TCM and using a variety of analytical methods and technology, to establish the objective, overall and multi index comprehensive evaluation system. The TCM fingerprint in one of the strategic subjects for TCM modernization. As more and more technologies have been applied to the fingerprint research of TCM, it is sure to play a much more important role in many aspects, such as the quality control of TCM, the researches of efficient components, and the mechanism in TCM, and so on. The fingerprint technology includes many modern technologies such as high-pressure liquid chromatography (HPLC). Corydalis yanhusuo is an ancient TCM, and recent years appears many researches about fingerprint of C. yanhusuo. This paper generalizes the research in progresses in research and analytical methods on fingerprint technology of C. yanhusuo, processed products (vinegar), and painkillers, to provide the scientific basis for fingerprint method and quality control of C. yanhusuo.

OBJECTIVEThis study aims to examine the prevalence and diameter of the bony canal structure of the posterior superior alveolar artery (PSAA), residual alveolar bone height, and distance of its inferior border from the alveolar crest using cone-beam computed tomography (CBCT).

METHODSCBCT images of maxilla in 116 patients were randomly selected from patients who underwent maxillary sinus augmentation procedure and/or posterior teeth implant therapy from April 2011 to September 2012. The lower border of the bony canal to the alveolar crest, diameter of the bony canal, and residual alveolar bone height below the sinus floor to the ridge crest were measured from CBCT scans. Data were presented using descriptive statistics.

RESULTSThe prevalence of the bony canal was 75.14% (133/177). The mean diameter of the bony canal was (0.96 ± 0.29) mm. The residual alveolar bone height was (7.14 ± 3.64) mm. The distance of the bony canal's inferior border from the alveolar crest was (17.92 ± 5.68) mm. No statistically significant differences between the right and left sides were observed (F = 0.295, P > 0.05). The mean diameter of the bony canal was significantly smaller in females than that in males (F = 0.187, P < 0.05). The maxillary alveolar dimension was significantly correlated with the residual alveolar bone height.

CONCLUSIONThe results from this study suggest that CBCT is a valuable tool in evaluating the presence of the bony canal of the PSAAs efore maxillary sinus surgery.
