In order to summarize and perfect the basic skill practicing method in acupuncture teaching and form a characteristic teaching, the research on skill training and technique improving of acupuncture and tuina major was carried out. The undergraduate students in acupuncture and tuina major from College of Acupuncture-Moxibustion and Tuina were randomly divided into an experimental group and a control group. Students from both groups received the basic courses of acupuncture-moxibustion and tuina as requested in the syllabus and the special teaching was added to the experimental group, namely "three practice" (strength practice, coordination practice, targeted practice of acupuncture basic skills) and "three enlightenment" (technique enlightenment, mind and qi enlightenment, efficacy enlightenment). During and after the courses, the teaching effectiveness was evaluated on the basis of needling manipulation. The peacetime score in the experimental group was superior to that in the control group (38.03 +/- 1.14 vs 33.25 +/- 1.31, P < 0.05), the total score in the experimental group was superior to that in the control group (84.03 +/- 6.30 vs 78.05 +/- 6.55, P < 0.05). The special teaching method of "three practice" and "three enlightenment" can improve the effect of skill training teaching method. It highlights the unique feature of central plains by integrating the essence of Shaolin internal qigong and Chen-style Taiji, it can also provide new ideas for the practical teaching of TCM professional courses and the construction of characteristic professionals.

OBJECTIVETo explore the clinical effect of manipulative reduction and lateral percutaneous K-wire fixation on supracondylar humerus fractures.

METHODSFrom Feb. 2004 to Jun. 2010,128 cases of supracondylar humeros fractures in children (96 boys and 32 girls) were treated by manipulative reduction and lateral percutaneous K-wire fixation. The average age of the children was 8 years old ranging from 2 to 15 years. Among them, 112 cases were extension fractures, 16 were flexion type; 102 cases belonged to ulnar deviation, and 26 cases belonged to radial deviation. After treatment, the elbow flexion range and carrying angle of the children were measured under the Flynn evaluation standard while considering the postoperative complications status to analyze the clinical effect on manipulative reduction and lateral percutaneous K-wire fixation.

RESULTSAll these children were followed up from 2 to 36 months (16 months on average). According to Flynn evaluation standard,the result were excellent in 116 children (90.6% of the total patients), good in 11 (8.6%), fair in 1 (0.8%). No infection, no ischemic muscular atrophy and no nerve damage had been found during the treatment.

CONCLUSIONThe manipulative reduction and lateral percutaneous K-wire fixation of supracondylar humerus fractures in children has small wound, is stable and reliable, easy to be operated, safe and effective and low cost. What's more, it can also avoid the complication caused by conservative treatment and operation. It is a good treatment of supracondylar humerus fractures in children.

Objective To analyze the diseases responsible for ophthalmoplegia and determine the optimal technique identifying the lesions. Methods CT and MR imaging findings of 1376 patients with ophthalmoplegia were analyzed. The total positive rate and ratio of the diseases causing ophthalmoplegia were calculated. The efficiency of various methods and sequences was compared in the evaluation of cavernous sinus inflammation and other lesions. Multi-paired samples Friedman test was used to compare five kinds of images from different methods and sequences, and Wilcoxon test was used to compare between every two kinds of images. Results The total positive rate was 91.9% (1264/1376). In 50 patients who underwent both CT and MRI, the positive rate of MRI (92. 0% ,46/50) was higher than that of CT (48.0% ,24/50)(Z = -4. 8, P ＜ 0. 01). There were 552 cases (43.7%) of cavernous sinus lesions, 518 cases (41.0%)of extraocular muscle diseases, 108 cases (8. 5%) of cranio-orbital communicating lesions and 86 patients (6. 8%) of other lesions. The five kinds of images from various methods and sequences had significant difference in the detection of 283 cavernous sinus inflammation (χ2 = 1047. 1, P ＜ 0. 01) cases. Transverse T1WI with thin slice thickness[(2. 71 ± 0. 69)scores]was better than that with thick slice thickness [(1.67 ± 0. 64) scores], contrast transverse T1 WI with thin slice thickness[(3.92 ± 0. 27) scores]was better than transverse T2WI with thick slice thickness, transverse T1WI and coronal T1 WI with thin slice thickness[(3. 10 ± 0. 39) scores]. Coronal T1 WI with thin slice thickness was better than transverse T1 WI with thin slice thickness and transverse T2WI, and the contrast coronal T1WI with thin slice thickness [(3.95 ± 0. 22) scores]was better than transverse T, WI with thin slice thickness, transverse T2 WI and coronal T1WI (P ＜0. 01 separately). The positive rate of enhanced MRI (100% ,39/39) was higher than that of nonenhanced MRI (82. 1% ,32/39) (Z = - 2. 1, P ＜ 0. 05). Conclusion CT and MRI can show the lesions responsible for ophthalmoplegia. MRI is the best examination method in displaying these lesions.

Objective To research the morphological classification of inferior angle of scapula based on CT 3D reconstruction and its clinical significance. Methods A total of 290 scapular bones data were collected from People's Hospital of Lu Xian County and measured based on CT 3D reconstruction. The scapular bones images were reconstructed by CT 3D technique. Reference points; g was the inferior scapular angle, n was the inferior glenotubular nodule, m was the intersection of the scapular ganglion and the medial edge of the scapula, k was the upper scapular angle, r was the notch of the scapular glenoid, h was the intersection of point g to mr. The parameters of inferior angles of 290 scapular bones, including the thickness of point g (the thickest part of inferior angle of the scapula), the length of the line gn, line gm, and line gh, and the angle of ∠ ngm, ∠ gmk (the projection of the scapular coronal plane), and ∠ gmk' (the projection of the scapular sagittal plane) were observed and measured by CT 3D technique. Results Under the CT three-dimensional reconstruction, the inferior angle of scapula was classified into three types; accessory angle-type ( 175, 60. 34%), U-type ( 81, 27. 93%) and V-type (34, 11. 73%). In addition, there was a significant difference between the auxiliary angle type and the V type on the thickest part of the g point and gn (P<0.05); U-type and V-type with paragonai gm-significant difference (P<0.05); There was a significant difference between the auxiliary angle type and the U shape on gh (P<0.05); there was a significant difference between the auxiliary angle type and the U shape on ∠ gmk' (P<0.05). There was a significant difference in the inferior angle of the bilateral scapula on mngm (P<0.05). Conclusion Based on the result of CT three-dimensional reconstruction, the inferior angle of scapulae have three anatomical types, with the accessory angle-type as the main type, and the morphology and classification of it are of certain clinical implication.

BACKGROUNDFractional flow reserve (FFR) is currently considered as the gold standard for evaluating the functional significance of coronary stenosis. However, its potential benefits in real-world practice remain unknown in China. This study aimed to test the hypothesis that the use of FFR is associated with improved outcome and reduced cost in Chinese real-world clinical practice.

METHODSA retrospective cohort study was carried out using the database of Second Affiliated Hospital of Zhejiang University, a tertiary and high-volume center in China. Clinical events were compared using the Cox proportional hazards model during a median follow-up of 13 months.

RESULTSThe study cohort consisted of 366 consecutive patients referred for coronary revascularization with adjunct FFR and 366 matched controls, from 2010 to 2014. Major adverse cardiac events (MACEs) (death, myocardial infarction, repeated revascularization, or hospitalization for angina) at 4 years were found in 12.0% of angiography-guided patients and 4.9% in the FFR-guided group (P < 0.001). The mean number of implanted stents was significantly lower in FFR treated subjects (0.52 ± 0.82 stents) compared with the angiography-guided group (0.93 ± 0.96 stents) (P < 0.001). No difference in overall costs at initial hospitalization was observed between angiography-guided percutaneous coronary intervention (PCI) compared with FFR-guided PCI (RMB 33,000 Yuan, range: RMB 7393-44,700 Yuan) versus RMB 21,200 Yuan (RMB 19,100-47,100 Yuan) (P = 0.54). However, costs for MACEs during follow-up were significantly reduced in the FFR-guided arm (P < 0.001).

CONCLUSIONSIn the contemporary clinical practice, FFR-guided PCI is associated with decreased use of stents, improved clinical outcome, and reduced costs, compared with angiography-guided PCI.
