OBJECTIVETo assess the clinical effectiveness of volar and radial column approach by plate fixation for the treat- ment of unstable fracture of distal radius.

METHODSAccording to Cochrane Systematic Review, Medline, Embase, Cochrane Li- brary, CNKI and CBM, randomised controlled trials (RCTs) of volar and radial column approach by plate fixation for the treat- ment of unstable fracture of distal radius were searched for from 1966 to 2014. Data analysis was performed with the Cochrane Collaboration's RevMan 5.0 software.

RESULTSTotally 391 patients of 6 RCTs and 2 retrospective cohort studys were included and divided into volar plate group (187 cases) and radial column plate group (204 cases). Meta-analysis result showed: compared with radial column plate group, volar plate group had significant difference in recovery of wrist function [SMD = 0.74, 95% CI (0.47, 1.01), P < 0.00001], Gartland-Werley scores [SMD = -1.39, 95% CI (-2.24, -0.53), P = 0.001], postoperative neural in- jury [OR = 3.67, 95% CI (1.37, 9.84), P = 0.01 1 and postoperative wrist pain [OR = 0.32, 95% CI (0.13, 0.74), P = 0.008]. But no significant difference was identified in DASH scores [SMD = -0.36, 95% CI (-0.97, 0.26), P = 0.25], radiographic result assess- ment [SMD = -0.18, 95% CI (-0.53, 0.16), P = 0.3], postoperative grip strength [SMD = 0.71, 95% CI (-0.12, 1.54),P = 0.09], postoperative tendinous damage [OR = 0.31, 95% CI (0.10, 0.98), P = 0.05] and carpal tunnel syndrome [OR = 0.96, 95% CI (0.63, 1.48), P = 0.87].

CONCLUSIONCompared with radial column plate internal fixation, volar approach plate fixation for treat- ment of distal radius intra-articular fracture has advantage of recovery of joint functionand. However, the volar approach plate fix- ation was associated with a higher risk of long-term complications than the radial column approach plate fixation.

Quorum sensing systems of pathogens are central regulators for the expression of virulence factors. Increasing evidence implies that targeting the quorum sensing system of many pathogenic bacteria is a promising therapeutic approach to control infections. In this work,we isolated 47 strains of actinomycetes from the mud sample of Jiaozhou Bay. Quorum sensing inhibitory activity was monitored by Chromobacterium violaceum CV026. As a result,the culture broth extract of actinomycetes WA-7 was found to have significant quorum sensing inhibitory activity. This strain was assigned to the genus Streptomyces based on its 16S rDNA sequence. Further investigation revealed that the extract could inhibit the quorum sensing-controlled violacein and proteases production of C. violaceum in a concentration-dependent manner.

Objective To investigate the effect and mechanism of transplantation of marrow multi- function stem ceils in treating femoral head necrosis.Methods Sixty japanese rabbits were divided into A,B and C groups randomly.After creation of the models of hormone induced necrosis of femoral head;A group was designated as the treatment,B as the control and C as the normal groups.The bone marrow of A group was extracted and isolated and then injected into the left femoral head and the right femoral head was decompressed by drilling only.The rabbits were killed at 8 weeks after the treatment and changes in various parameters were observed,including imaging data of molybdenum target films,CT and MRI;routine pathology with HE staining and ultrastructural alteration by election microscopy.Results Eight weeks after the treatment of transplantation of marrow multifunction stem cells,the X-ray showed only a little change but the typical appearances were revealed by CT and MRI.Pathohistologic manifestation demonstrated decrease of empty bone lacuna,increase of osteoblast and new bone formation.Election microscopy displayed abundant organelles in osteoblasts with few empty bone lacuna,in addition the tansplantation of marrow multifunction stem cells could obtain better reconstraction for the involved femoral head.Conclusions The treatment of transplantation of marrow muhifunction stem cells in femoral head necrosis could accelerate the process of repairing,worthy to be acknowledged as a good and valuable management in rabbits.(J Intervent Radial,2007,16:122-126)

Objective To investigate the renal function changes of the children with breast milk jaundice(BMJ) and effect of early interference treatment on renal function. Methods Serum bilirubin and urine - minim protein (?2-MG,?1-MG, Alb and IgG) of the 50 patients with BMJ were measured when they were in hospital within 12 hours and the last day separately , at the same time, 20 healthy newborns had been chosen to serve as control group. Results Compared with control group, the urine minim protein of treatment group increased with the rise of serum bilirubin. When serum bilirubin was 205.2 - 256.5 ?mol/L, urine ?2- MG had mild increasing (P

OBJECTIVETo investigate the effects and mechanisms of sodium ferutate (SF) in treating diabetic nephropathy (DN).

METHODSEighty patients of diabetes mellitus type 2 with DN were randomly divided into two groups, 40 cases in each group. The routine group treated with conventional treatment including dietary therapy and hypodermic injection of insulin, and the SF group treated with intravenous dripping of SF 300 mg/d additionally besides the conventional therapy, the therapeutic course for both groups was 4 weeks. And 40 healthy volunteers were allocated in a group for normal control. Before and after therapy, levels of fasting blood glucose (FBG), hemoglobin A1c(HbA1c), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), serum creatinine (SCr), blood urea nitrogen (BUN), mean arterial pressure (MAP), urinary albumin excretion rate (UAER), serum collagen type IV (CIV) and endothelin (ET) were detected.

RESULTSAfter 4 weeks of treatment, FBG and HbA1c reduced obviously in both groups with insignificant difference in comparison of them (P > 0.05). Before treatment, TG, TC, MAP, SCr, BUN, UAER, CIV and ET were markedly higher in DN patients than those in the health control (P < 0.05), these criteria decreased significantly in the SF group (P < 0.05) but insignificantly in the routine group (P > 0.05) after treatment, showing difference between the two groups (P < 0.05).

CONCLUSIONSodium ferulate could ameliorate lipid metabolic disorder, reduce blood pressure, lower UAER and CIV level, and improve renal function in DN patients, the mechanism might be through decreasing ET production and inhibiting the combining of ET with its receptor.

Severe tricuspid regurgitation with permanent pacemaker wire passing through the orifice of bioprosthetic tricuspid valve is extremely rare. We present a case of such kind of patient and redid bioprosthetic tricuspid valve replacement. A hawk mouth forceps for bone surgery was used to cut off the mental ring of ruined bioprosthetic tricuspid valve and the ruined valve was removed. A new bioprosthetic tricuspid valve was implanted and the wire of permanent pacemaker was left outside the ring of bioprosthetic tricuspid valve. This method may be helpful for such kind of patient.

OBJECTIVESTo research radiographic anatomy of the main structure of the pelvic Teepee view, including its azimuth direction and view anatomy structure.

METHODSFrom June 2013 to June 2014 adult pelvic CT examination results were filtered, excluding skeletal deformities and pelvic osseous destruction caused by tumors, trauma, etc. The data of 2.0 mm contiguous CT scan of 9 adults' intact pelves was,selected and input into Mimics 10.01 involving 7 males and 2 females with an average age of (41.2±10.3) years old. Utilizing the software, the 3D CT reconstructions of the pelves were completed. Setting the transparency being high,the pelvic 3D reconstructions were manipulated from the pelvic anteroposterior view to the combined obturator oblique outlet view and fine-tuned till the regular Teepee-or teardrop-shaped appearance emerges. Cutting tools of the software were at the moment applied to separate the "Teepee" from the main pelvis for each reconstruction. Then the "Teepee" and the rest (main) part of the pelvis were displayed in different color to facilitate the analysis on the Teepee, iliac-oblique, and anteroposterior views.

RESULTSThe "Teepee" started from the posterolateral aspect of the anterior inferior iliac spine and finished at the cortex between the posterior superior iliac spine and the posterior inferior iliac spine in a direction of being from caudal-anterior-lateral to cranial-posterior-medial. The radiographic anatomical composition of the "Teepee" contained one tip, one base,and two aspects. With the inner and outer iliac tables being the inner and outer aspects of the "Teepee", the tip is consequently formed by their intersection. The base is imaged from the cortex of the greater sciatic notch. The medial-inferior-posterior portion of the "Teepee" contains a small part of sacroiliac joint and its corresponding side of bone of the sacrum.

CONCLUSIONSThe "Teepee" is a zone of ample osseous structures of the pelvis, aside from a small medial-inferior-posterior portion, the main zone of which can be accepted as a safe osseous zone for the anchor of implants stabilizing certain pelvic and acetabular fracture patterns. The Teepee view can be utilized as guidance for the safe percutaneous insertion of such implants.

OBJECTIVETo study the effect of gene expression of mouse uroplakin II (UPII) promoter on human bladder cell cancer cell line.

METHODSThe mRNA expression of different cell lines was quantified by RT-PCR. Green fluorescent protein (GFP) and luciferase (Luc) were used as reporter genes. The plasmids carrying UPII or GFP were constructed and transfected into human cell lines of bladder transitional cell cancer (BIU-87), kindey cancer (GRC-1), vascular endothelium (EC), lung cancer cell line (A549) and skin fibroblast cell line (Hs27). GFP activity of cells was detected by confocual microscopy and flow cytometry (FCM). Luciferase value was measured by luminometer (microplate) and luciferase to beta-galactosidase ratios (L/G values) were used for evaluating transfection efficiency.

RESULTSRT-PCR showed high expression level of UPII mRNA in bladder cancer cell line BIU-87, whereas low level or no expression in nonbladder cancer cell lines. The activity of GFP in bladder cancer (BIU-87) cell was higher than that in the other cell lines (5 - 10/HP versus 0 - 2/HP), with 4.34% positive cells in BIU-87 detected by FCM, but no positive cell was found in the other cell lines. L/G values indicated that the luciferase expression in human bladder cancer cells transfected with mouse UPII promoter was 1.8 - 8.2-fold as high as that in the nonbladder cell lines.

CONCLUSIONMouse UPII promoter gene can be expressed in a tissue-specific fashion in human urinary bladder cancer. It is capable of initiating transcription of reporter genes in human bladder cancer cell line.

OBJECTIVETo develop an efficient non-viral gene delivery system in order to transfer CDKN1B gene efficiently into lung and liver carcinoma cells.

METHODSA recombinant plasmid composed of CDKN1B sequence and EYFP as reporter gene was constructed and identified. The recombinant DNA was then formulated the lipids-polycation-DNA complexes(LPDs) with protamine sulfate. Several kinds of lung and liver carcinoma cells were transfected by means of LPDs. The physicochemical properties of LPDs were investigated using PCS method and TEM, respectively. The expression of EYFP in A549 cells was observed under fluorescent microscope and evaluated by flow cytometry analysis. Finally, the production of CDKN1B protein in transfected LLC, Chang and 7721 cells was identified by Western blot analysis.

RESULTSThe average diameter of the LPDs were 167 nm with the polydispersity index of 0.35. The average zeta potential of LPDs was +32.6 mV. LPDs look like a sunken sphere. The fluoresent microscope picture clearly indicated the expression of EYFP in A549 cells. The flow cytometry result showed that the transfection efficiency of LPDs in A549 cells was comparable with that of LipofectAMINE, the positive control. Western blot analysis confirmed the production of CDKN1B protein in LLC, Chang and 7721 cells transfected with LPDs, while no CDKN1B protein was detected in cells transfected with naked DNA.

CONCLUSIONThe construction of the recombinant plasmid is successful. LPDs can deliver the recombinant plasmid to lung carcinoma cells and liver carcinoma cells with high efficiency. Therefore, this kind of gene delivery system has the potential uses for the treatment of lung and liver cancer.
