Currently, the randomized controlled trial (RCT) becomes the generally accepted golden standard for clinical trials. It can be classified into two types based on different design, that is, the explanatory randomized controlled trial (ERCT) and the pragmatic randomized controlled trial (PRCT). In designing a clinical trial, researcher may select either of them according to the goal of research. The design feature of PRCT and its application in designing clinical trials of acupuncture were introduced in this paper. Further attention should be paid on resolvent of how to apply PRCT in combining with other design methods organically to work out clinical trial scheme with high quality and consistent with the characteristics of acupuncture as possible, for evaluating the effect of acupuncture more accurately and objectively, so as to promote the international application and development of acupuncture therapy.

OBJECTIVETo explore if vasculogenic mimicry (VM) exists in hepatocellular carcinoma (HCC) and to explain the clinical significance of VM.
METHODSNinety-nine HCC resection specimens with complete clinical and prognostic data were collected. Immunohistochemical staining of CD31 and CD105, hepatocyte and PAS staining of the histological preparations were conducted to explore if VM exists in those HCC.
RESULTS12.12% (12 specimens) of the 99 specimens exhibited evidence of VM. One of 40 HCC specimens (2.5%) which belong to Edmondson pathologic grade I-II exhibited VM; 11 of 59 HCC specimens which belong to Edmondson pathologic grade III-VI (18.64%) exhibited VM, the low differentiated HCC (grade III-VI) exhibited more VM specimens than the high differentiated HCC (grade I-II) (chi2=4.416, P < 0.05). The biological behavior of VM was assessed and the stages of the cancers, using the TNM (tumor, node, metastases) classification criteria, were analyzed. These parameters of the VM and non-VM groups were compared. The mean TNM stage of the VM group was not more advanced than that of the non-VM group. The hematogenous metastases ( lung, bone, peritoneum et al) between the 2 groups were compared, and in the VM group the hematogenous metastasis rate was higher (chi2=8.873, P < 0.01). Kaplan-Meier actuarial survival curves were used to compare the VM group (n = 12) with the non-VM group (n = 87). Median survival time of the VM group was 9 months and that of the non-VM group was 31 months. The VM group had a lower survival rate than the non-VM group (P < 0.01).
CONCLUSIONVM exists in HCC, and the higher invasive HCCs exhibit more VM than the less invasive HCCs. The HCC patients in the VM group had a higher rate of hematogenous metastases, a lower survival rate, and a poorer prognosis.

OBJECTIVETo summarize the experiences of cardiopulmonary bypass (CPB) techniques in 15 patients of orthotopic heart transplantation.
METHODSAll patients received mild hypothermia and high flow rate perfusion. Effective strategies were taken to protect myocardium, lung, kidney, and blood conservation. The donor hearts were arrested with aorto perfusion using 1 000 ml St. Thomas solution at 4 degrees C, perfused with 1 000 ml University of Wiscosin (UW) solution or Histidin-Tryptophan-Ketoglutarat (HTK) solution at 4 degrees C, and then preserved in ice saline. Ice mud was covered on the donor heart during anastomosis. Low potassium cardioplegia solution was perfused before the unclamping of aorta.
RESULTSThe CPB time was (165.2 +/- 22. 8) min, the warm ischemia time was ( 7. 7 +/- 1. 7) min, and the cold ischemia time was ( 142. 4 +/- 11. 5) min. Heart beats was automatically recovered in 10 patients, and was recovered upon defibrillation in 5 patients. Left ventricular ejection fractions were (64. 1 +/- 4. 6) % after one month. All patients survived.
CONCLUSIONProper CPB management and effective donor heart protection are essential to guarantee the success of heart transplantation.

OBJECTIVETo establish a method of SYT-SSX fusion gene detection by FISH and to explore its diagnostic value for synovial sarcoma.
METHODSThe presence of SYT-SSX fusion gene was determined by FISH using a tissue microarray containing 62 known synovial sarcomas, 60 non-synovial sarcomas and 133 equivocal synovial sarcomas. FISH results were compared with those of RT-PCR published previously.
RESULTSOverall, 96.9% (247/255) of the cases were successfully analyzed by FISH. The sensitivity of FISH for known synovial sarcomas was 96.7% (58/60), and the specificity for the non-synovial sarcoma was 100% (59/59). Moreover, SYT-SSX gene fusion was detected in 78.1% (100/128) of the equivocal synovial sarcomas. The concordance rate between FISH and RT-PCR was 83.6% (102/122) in those equivocal synovial sarcomas, and overall 79.7% (106/133) of these cases were confirmed as synovial sarcomas either by RT-PCR or by FISH.
CONCLUSIONSThe sensitivity and specificity of FISH detection of SYT-SSX fusion gene are high. FISH and RT-PCR are complementary to each other in the confirmation of synovial sarcomas, particularly those questionable cases.

BACKGROUNDBeta-catenin, a 92 kDa protein that binds to the cytoplasmic tail of E-cadherin, has an essential role in intercellular adhesion and signal transduction. Aberrant expression of beta-catenin has been associated with progression and metastasis of various human cancers. The aim of this study was to elucidate the expression pattern of beta-catenin in primary oral squamous cell carcinoma and examine the correlation between beta-catenin expression and tumor differentiation, histological grade and lymph node status as well as its clinical significances.
METHODSSeventy-six patients with oral squamous cell carcinoma and sixteen metastatic lymph nodes were studied. The beta-catenin expression was determined by immunohistochemical staining. The correlation with clinical, histological data was analyzed statistically.
RESULTSNormal oral epithelium showed strong beta-catenin expression at the cell membrane, but no cytoplasmic or nuclear expression. Different degrees of reduced expression of beta-catenin at the cell membrane were found in 54 cases with squamous cell carcinoma (71%). Cytoplasmic beta-catenin expression was found in 17 tumors (22.4%). Three cases were found with nuclear beta-catenin expression. In sixteen lymph nodes with metastatic squamous cell carcinoma, negative beta-catenin expression at the cell membrane was seen in 13 tumors (81.2%) and weak expression in 3 tumors (18.8%). Statistical analysis showed that there was an inverse correlation between beta-catenin expression and lymph node status and histological grade of tumors.
CONCLUSIONSReduced beta-catenin expression at the cell membrane is clearly associated with lymph node metastasis. A reduced expression of beta-catenin may constitute a hallmark of aggressive biological behavior of squamous cell carcinoma.

OBJECTIVETo investigate the safety and efficiency of the disposable circumcision suture device (DCSD) in the surgical treatment of phimosis and redundant prepuce.
METHODSWe randomly assigned 249 outpatients with phimosis or redundant prepuce to be treated with DCSD (n = 129) and by conventional circumcision (CC, n = 120), respectively. Then we compared the safety and efficiency of the two strategies.
RESULTSComparisons between DCSD and CC showed that the operation time was (4.02 +/- 0.69) vs (30.8 +/- 4.05) min, blood loss was (1.07 +/- 1.29) vs (8.72 +/- 2.15) ml, intraoperative pain score was 0.81 +/- 0.81 vs 2.42 +/- 1.15, 24-hour postoperative pain score was 1.84 +/- 1.02 vs 4.99 +/- 1.36, postoperative complication rate was 13. 95% (18/129) vs 9.17% (11/120), wound healing time was (13.99 +/- 9.06) vs (17.48 +/- 3.49) d, satisfaction with the penile appearance was 98.4% (127/129) vs 95% (109/120), and treatment cost was (2215.62 +/- 17.67) vs (576.47 + 15.58) Y RMB. DCSD exhibited obvious superiority over CC for shorter operation time, less blood loss, milder intraoperative pain, sooner wound healing, and better penile appearance, but it also had a higher rate of postoperative complications (P > 0.05) and involved more treatment cost than the latter (P < 0.05).
CONCLUSIONThe disposable circumcision suture device affords ideal clinical effects and therefore deserves clinical popularization.
