Acupuncture clinical trials are designed to provide reliable evidence of clinical efficacy, and SCI papers is one of the high-quality clinical efficacy of acupuncture research. To analyze these papers published in high impact factor journals on acupuncture clinical trials, we can study clinical trials from design to implementation, the efficacy of prevention and cure, combined with international standard practices to evaluate the effectiveness and safety of acupuncture. That is the core of acupuncture clinical trials, as well as a prerequisite for outstanding academic output. A scientific and complete acupuncture clinical trial should be topically novel, designed innovative, logically clear, linguistically refining, and the most important point lies in a great discovery and solving the pragmatic problem. All of these are critical points of papers to be published in high impact factor journal, and directly affect international evaluation and promotion of acupuncture.

Objective To evaluate the effect of discussion-based teaching pattern in clinical noviciate of general surgery. Methods Two hundred and ten students majoring in clinical medicine were randomly divided into the trial group and the control group during clinical noviciate of general surgery.There were 105 students in each group. The discussion-based teaching pattern and traditional teaching pattern were performed in the trial and control groups,respectively. After the clinical novici-ate of general surgery was completed,the teaching effects of both groups were evaluated by the exam-ination performance analyses and the questionnaire-based survey. Student's t-test andχ22 test were used in statistical analysis. Reults The rate of satisfaction with the teaching pattern was 88.6%in the trial group and 70.5%in control group(P<0.05). The mean scores in the trial group and control group were 80.3±9.2 and 74.5±11.3,respectively (P<0.05). The pass rate of examination in the trial group and control group were 97.1% and 88.6%,respectively (P<0.05). The excellence rate in the examination was 24.8%in the trial group and 12.4%in control group (P<0.05). The overwhelming majority of stu-dents in the trial group thought that the discussion-based teaching pattern had more advantages in im-proving students' learning initiative and enthusiasm,ability to analyze and solve problems,etc.,acord-ing to the questionnaire-based survey. Conclusions Discussion-based teaching is an effective teach-ing pattern and superior to the traditional teaching pattern.

Objective To analyze the clinical profile and short-term postoperative prognosis of mixed hepatocellular carcinoma and cholangiocarcinoma (mHCC-CC). Methods Clinical data of 17 mHCC-CC cases undergoing hepatectomy were retrospectively analyzed. Results Patients average age was 53 years (27～76 years).There were 11 males (64.7％) and 6 females.Ten patients (58.8％) were asymptomatic,twelve patients(70.6％ ) had positive serology for hepatitis B infection,serum AFP levels ＞25 ng/ml in 12 cases. Serum CA199 levels ≥ 37 U/ml in 4 cases. All patients underwent radical hepatectomy,including ＞ 1.5 cm safe margin and lymphadenectomy.The 6-,12-,and 18-months overall survival rate was 93.8％,86.5％ and 57.7％,respectively.The 100- and 200-day disease-free survival was 65.3％ and 43.5％.The median disease-free survival was 161 days. Conclusions mHCC-CC is difficult to diagnose preoperatively.The diagnosis depends on pathological examination.The main treatment was surgical resection.The prognosis of mixed primary liver cancer is poor and tends to recur early after hepatectomy.

Objective To evaluate the feasibility and diagnostic accuracy of CE-MRA with low dose contrast agent by comparison with DSA in diabetic patients with peripheral arterial diseases. Methods ( 1 )Study in vitro: test tubes containing Gd-DTPA of different concentrations were scanned, and the relationship between signal intensities and concentrations of GD-DTPA was analyzed. DSA and CE-MRA with selected concentrations of Gd-DTPA were performed on stenotic vascular models to estimate the proper low dose of GD-DTPA for clinical applications. (2) Clinical applications: 78 diabetic patients with peripheral arterial diseases were scanned from the abdomen and pelvis station to the calf-foot station in a 3 T MR system with standard bolus chase 3D CE-MRA sequence after injection of 13 ml GD-DTPA . The image quality,diagnostic rate of stenosis of arteries in calf and degree of venous contamination were evaluated with Fisher's exact test. DSA images of 220 vascular segments in 22 patients ( 10 segments per patient) were acquired as the gold standard and compared with CE-MRA by using Kappa test. Results The MR signal intensities were proportional to the concentrations of contrast agent in present study, and all stenotic segments of vascular model were displayed by CE-MRA with GD-DTPA at lower concentration of 1.5 mmol/L. As for MRA images of 78 diabetic patients with low dose Gd-DTPA, about 97.4% (76/78) showed diagnostic image quality for pelvic and thigh stations. But the MRA images of lower extremities were interfered by the venous contamination significantly (P ＜ 0.01 ). Compared with DSA for 22 patients, the diagnostic sensitivity, specificity and agreement coefficient (Kappa value) of MRA were 96. 0% ( 168/175), 73.3%(33/45), and 0.72 (P＜0.01), respectively. Conclusion Using 3.0 T MR scanner, high quality CE-MRA of lower limb arteries can be obtained for clinical applications with contrast agent dose as low as 13 ml,which has comparable diagnostic sensitivity and specificity with DSA. But the limitation of venous contamination in MRA image should be resolved in further studies.

Objective To investigate the relationship between insulin resistance and erythrocyte in- sulin receptors in patients with gout associated with macroalbruminuria(MAU).Methods FBG,PBG,FINS, P2hINS,CH,TG,HDL,LDL-c,UA and erythrocyte insulin receptors were determined in 44 patients with MAU,62 patients with normal MAU(NMAU).Results In MAU,the levels of FINS,TG,LDL-c and HOMA-IR were(16?4)mU/L,(2.5?0.6)retool/L,(3.2?0.5)mmol/L and 3.6~1.2 respectively.While they were(13?3) mU/L,(2.3?0.8)mmol/L,(3.0?0.5)mmol/L and 3.0~0.4 in NMAU group.The levels of FINS,TG,LDL-c and HOMA-IR were significantly higher in the MAU patients than those in NMAU patients(P

Objective Although aspirin resistance has been recognized to occur in patients with diabetes mellitus, the prevalence and related risk factors for aspirin resistance in elderly patients with diabetes mellitus have not been reported yet. The purpose of the present study was to evaluate the prevalence and potential risk factors for aspirin resistance in elderly patients with type 2 diabetes.Methods The 140 elderly patients [aged from 60 to 92 years, mean age (73.8±8. 0) years] with type 2 diabetes receiving daily aspirin therapy (≥ 75 mg) over one month were recruited. Platelet aggregation was measured by light transmittance aggregometry (LTA) and thrombelastograph (TEG)platelet mapping assay. Results By LTA, 6 patients (4.3%) of the diabetic patients were found to be resistant to aspirin therapy, 44 patients (31.4 %) were semi-responders. By TEG, 31 patients (22. 1%) were aspirin resistant. Among the 31 patients who were aspirin resistant by TEG, 3 were aspirin resistant by LTA. In the multivariate logistic regression analysis, female gender (OR= 5. 54,95%CI: 1.17-27.47, P=0.036) and homocysteine level (OR=1.15, 95%CI: 1.00-1.35, P=0. 043) were statistically significant risk factors for aspirin resistance by TEG. Conclusions The prevalence of aspirin resistance in elderly patients with type 2 diabetes is considerably higher in elderly female patients and in elderly patients with higher serum homocysteine level.

BACKGROUNDReports of applying cervical pedicle screw (CPS) system in the posterior cervical spine surgeries are limited because of its inherent risk of neurovascular injury. The clinical results of cervical spine instability treated with CPS system were retrospectively analyzed, and the clinical efficacy and safety of this management were evaluated.

METHODSTwenty-five patients with cervical spine instability undergoing posterior C3 - C7 single/double door laminoplasty and free-hand CPS fixation as well as graft fusion were investigated; of whom, 3 were due to trauma, and 22 degenerative cervical pathogenesis. One hundred and fifty in total, CPSs were implanted in 5 cervical segments for 1 patient, 4 for 2, 3 for 18, and 2 for 4. Japanese Orthopaedic Association (JOA) score and its improvement rate, neck disability index (NDI), segmental stability, pedicle cortex perforation rate and other complication-associated parameters were assessed.

RESULTSThe average follow-up was 16.6 (6 - 30) months. Compared with pre-operative values, JOA score improved by 4.10 +/- 0.84 points on average (P < 0.05) at 6 months post operation, with a mean improvement rate of 61%. While the pre-operative and 6-month post-operative NDI were 32.96 +/- 6.13 and 16.84 +/- 4.40 (P < 0.05), respectively. At 6-month post-operation and the final follow-up, fused segments were stable. Pedicle cortex perforation rate was 8.0%, with no neurovascular complications observed.

CONCLUSIONSAnatomizing the pre-operative radiographic data facilitates the precise operative design prior to surgery; and CPS system is capable of offering safe and satisfying outcomes in the management of cervical spine instability.
