Background and purpose: Sorafenib, a multiple targeted agent, can inhibit proliferation and induce apoptosis of diverse tumor cell in vitro. It has extensive biological activities, but the pancreatic cancer effect of monotherapy is poor. This may be related to nuclear factor-kappa B (NF-κB) pathway activation in cancer. Therefore, it is necessary to combine with Pyrrolidinedithiocarbamate (PDTC, a NF-κB activation inhibitor) to enhance curative effect. To investigate the influences of cell proliferation, cell cycle and expression of NF-κB via their acting on human pancreatic cancer PANC-1, and explore their possible mechanism. Methods:The experiment groups were divided into sorafenib group with different concentrations (1.5, 3.0, 6.0, 12.0 μmol/L), PDTC group with different concentrations (10.0, 25.0, 50.0, 100.0 μmol/L) and combination group with low concentration (3.0 μmol/L sorafenib+25.0 μmol/L PDTC). The proliferative activity of PANC-1 of each group was measured by MTT assay at different time points of 24

Objective To evaluate the early clinical efficacy of subfascial endoscopic perforator vein surgery (SEPS) in the treatment of chronic venous insufficiency (CVI) of lower limbs. Methods A retrospective study was carried out in 26 patients (34 legs) with CVI treated by SEPS. Results The number of incompetent perforating veins ligated per limb ranged 1～5 (mean, 3 5). The postoperative clinical score (2.48?0.25) was significantly lower than the preoperative score (6.54?0.93) ( t =21.497, P

Objective To investigate the risk factors for nosocomial bacteremia and decrease the prevalence of nosocomial bacteremia.Methods We collected the data of bacteremia patients in our hospital from January,2006 to December,2009.According to the criterion of nosocomial infection,the patients were divided into nosocomial bacteremia group (83) and community-onset bacteremia group (119).The influence of a series of variables on the development on both types of bacteremia was analyzed by Student＇s t test and x2 test.The risk factors were performed using multivariate logistic regression.Results Compared to that of community-onset bacteremia group,the proportion of malignancy (21/83 vs 12/119,x2 =8.2846,P ＜ 0.01 ),venous catheter ( 28/83 vs 3/119,x2 =36.67,P ＜ 0.01 ),diabetes ( 37/83 vs 0/119,x2 =68.226,P ＜0.05),surgical operation(37/83 vs 0/119,x2 =68.226,P ＜0.01),previous antibiotics(78/83 vs 10/119,x2 =173.5657,P ＜ 0.01 ) in nosocomial bacteremia group were higher.Multivariable logistic regression analysis showed that only 4 factors were significantly and independently responsible for nosocomial bacteremia,They were malignancy ( P ＜ 0.05,OR =3.186),diabetes ( P ＜0.001,OR =4.821 ),venous catheter( P ＜ 0.05,OR =2.135),previous antibiotics ( P ＜ 0.05,OR =2.135 ).The bacteria in nosocomial bacteremia group showed more ability to resist to antibiotics.Conclusions We should pay more attention to the patients with diabetes or malignancy or venous catheter or previous treated with antibiotics.These patients have more chances to develop to nosocomial bacteremia and infect by the drug-resistant bacteria.

Objective To analyze the image and histological results of the combined use of allograft/extracorporeally frozen tumor-bearing bone and vascularized fibular flap for the reconstruction of bony defects following tumor resection,guiding clinical practice.Methods From March 2007 to June 2013,we enrolled 63 patients who had combinative biological reconstruction after bone tumor resection (11 in humerus,22 in femur,21 in tibia,4 in calcaneus).There were 36 male and 27 female in this series.The average age at time of operation was 20 years,ranging from 9 to 48 years.The follow-up ranged from 16 to 102 months with average of 48 months.We investigated the X-ray and CT images for all patients and histological findings of two patients.Patients were assessed functionally with the Musculoskeletal Tumor Society 93 score.Results Three patients with local soft tissue recurrence and one patient with infection underwent amputation.The survival of construct was 93.6％.Bone union achieved in all cases with the average MSTS score of 92.8％.Bone union ranged from 11 to 28 months in allograft group and 9 to 14 months in devitalized tumor bearing bone group.Significant difference of bone union time was found between two groups (Z=-3.638,P=0.000).Viability of the fibular grafts was verified in 58 of 63 patients (92％).Three types of images were observed in complex.Osteopenia and spongy change in fibula were found in 51 patients (81％) with stable fixation of the complex.Five complexes with failed blood supply of fibula and stable fixation revealed no density change of fibula,small amount of callous formation and relative delayed union.In seven complexes (11％) with unstable complex due to patients' incompliance,fibula reacted with dense hypertrophy and microfracture.Fusion of grafts with amount of callus was obviously observed.Union at allograft-host bone junctions occurred by residual host bone-derived external callus and fibular-derived internal callus that bridged the junction and filled the gap between abutting cortices.Callus from fibular graft was mature than that from periosteum of residual host bone.Internal repair was observed at the internal surface of the allografts.Fibula showed significant spongy changes.Conclusion Recycled tumor-bearing bone in combined with fibular flap is a reliable reconstruction as an alternative to traditional Capanna technique.The survival of the fibula is a cornerstone in success of complex reconstruction.Sponginess of fibula and internal repair of allograft compromise the intensity of complex,necessitating the strong instrumentation during reconstruction.

Objective To collect data and analyze the current status and prevalence changes of Crohn's disease (CD) in mainland China in recent decades. Methods A computer-based literature search was previously performed by using 50-year (1950 to 2002) of records of CD from the Chinese Database of Biology and Medicine (CBM) (1979 to 2002) and a manual year-by-year search of the literature ( 1950 to 1978). Using similar method, descriptive epidemiological data from 2003 to 2007 were collected, analyzed and compared with previous research. Results Four hundred and seventeen relevant papers during 2003 and 2007 were collected and 62 papers were eligible for inclusion. Within 62 papers, a total of 2149 cases with CD from 2003 to 2007 have been reported nationwide, comprising 1288 male and 861 female patients, result (ie,1526 cases from 1950-2002). There were no obvious changes in incidence age (younger and middle age were main components) and sex ratio ( number of male was still larger than that of female). The extrapolated CD incidence and prevalence rates were 1.21/100 000 person ? year and 2.29/100 000, respectively, which were higher than that of year 1950-2002, 0.28/100 000 person ? year and 1.38/ 100 000, respectively. Conclusions The incidence and prevalence rates of CD have been increasing rapidly, but these rates are still lower than those in Western world.

Objective To investigate the anatomical features, operative method and efficacy of internal fixation in the treatment of iutra-articular fractures of caleaneum via the sinus tarsi approach. Methods The pathway, branches distribution and anastomosis of perforating descending branch of peroneal artery were observed on 18 adult cadaveric lower limbs. A sinus tarsi approach was designed. From July 2001 to January 2008, 71 intra-articular calcaneal fractures in 68 patients were treated with open reduction and internal fixation via sinus tarsi approach at lateral sides of calcaneus. According to the Sanders classification, there were 26 type Ⅱ fractures, 32 type Ⅲ fractures and 13 type Ⅳ fractures. Results All patients were followed up for a mean period of 39.3 months (13-85 months), and the fractures were completely healed. There was a significant difference in the length, width and height of the calcaneus, Bohler angle and Gissane angle before and after operation (P < 0.01). According to Maryland Foot Score, the operative effect was excellent in 33 feet, good in 29 feet, fair in 6 feet and poor in 3 feet. Conclusion Open reduction and internal fixation via sinus tarsi approach is an effective method for minimally invasive treatment of intraarticular fractures of the calcaneus, with the advantages of good clinical results and causing minimal damage to soft tissues.

Primary hypertension is one of the common chronic diseases, as well as the key disease for prevention and treatment by traditional Chinese medicine (TCM). The authors searched and analyzed RCTs studies on primary hyper-tension treatment with acupuncture in the PubMed. It showed that primary hypertension treatment with acupuncture abroad had high quality methodologies. However, the deficiencies of TCM theories in the treatment plan in these studies were the same as RCTs of acupuncture treatment design of other diseases. It may due to the insufficiency of TCM knowledge and culture differences of researchers aboard. Besides, the small sample amount, various interven-tions, no blank control, and the using of 24-hour ambulatory blood pressure most of the time, may difficult to objec-tively evaluate the clinical effect of acupuncture. Therefore, our research team will carry out high quality RCT stud-ies under the guidance of TCM theories of meridians and syndrome differentiation to further discuss the specificity of acupoints.

OBJECTIVETo investigate the correlation between articulation, velopharyngeal function, and surgical age by comparing the changes in articulation after velopharyngeal closure is performed. This study is also conducted to investigate the influencing factors of omission change between pre- and post-operation.

METHODSA total of 48 patients, including 18 males and 30 females, mean age (13.3 ± 5.8) years, with non-syndromic cleft lips and palates were selected from January 2011 to December 2011. Their speech data and articulation between pre- and post-operation were retrospectively analyzed using non-parametric tests. Correlation study was performed to analyze the influencing factors of the changes in articulation. P < 0.05 was considered statistically significant.

RESULTSThe difference in articulation after velopharyngeal closure occurred was significant (Z = -3.796, P = 0.000). A negative correlation between the ratio of post-operative normal articulation and surgical age (R = -0.487, P = 0.000) was observed. The change in omission was positively correlated with surgical age (R = 0.589, P = 0.000) and gender (R = 0.404, P = 0.047). By comparison, the change in omission was negatively correlated with follow-up time (R = -0.235, P = 0.040).

CONCLUSIONArticulation and intelligibility are significantly improved after velopharyngeal closure is performed. These parameters are negatively correlated with surgical age to some extent. In addition, the change in omission is positively correlated with surgical age and gender, whereas the change in omission is negatively correlated with follow-up time.
