Background: Iliac vein compression syndrome (IVCS) is an important cause of deep vein thrombosis, but the incidence of IVCS is still unclear. The purpose of this prospective study was to determine the incidence of IVCS in an asymptomatic patient population and to evaluate the risk factors in patients with and without IVCS. Methods: From October 2011 to November 2012, a total of 500 patients (228 women and 272 men; mean age of 55.4 ± 14.7 years) with no vascular?related symptoms were enrolled in this study. Computed tomography was performed to evaluate all patients. The degree of venous compression was calculated as the diameter of the common iliac vein at the site of maximal compression divided by the mean diameter of the uncompressed proximal and caudal left common iliac vein (LCIV). We compared the stenosis rate of the common iliac vein in women and men according to age and followed up patients to evaluate outcomes. Results: The mean compression degree of the LCIV was 16% (4%, 36%); 37.8% of patients had a compression degree ≥25% and 9.8% had a compression degree ≥50%. There was a significant difference between men and women in the LCIV compression degree (9% [3%, 30%] vs. 24% [8%, 42%]; U = 4.66, P < 0.01). In addition, the LCIV compression degree among younger women (≤40 years) was significantly different compared with that in older women (>40 years) (42% [31%, 50%] vs. 19% [5%, 39%]; U = 5.14, P < 0.001). Follow?up was completed in 367 patients with a mean follow?up of 39.5 months (range, 6–56 months). The incidence of IVCS in the follow?up period was 1.6%. Stenosis rate and the diameter of the site of maximal compression correlated with the incidence of IVCS. Multivariable Cox regression analysis showed that the stenosis rate was an independent risk factor of IVCS (Wald χ2 = 8.84, hazard ratio = 1.13, P < 0.001). Conclusions: The incidence of IVCS was low and correlated with the stenosis rate of iliac vein. Preventative therapy may be warranted for common iliac vein compression in patients at an increased risk of venous thromboembolism, especially patients with a higher iliac vein compression degree.

BACKGROUND: Recent study showed that osteocalcin may elevate Insulin secretion and sensitivity, prevent the fat accumulation, play a role in the metablism of glucose and lipid. Undercarboxylated osteocalcin works as the main role. OBJECTIVE: To investigate the effect of different concentrations of glucose on osteoblast undercarboxylated osteocalcin. METHODS: The rib trabeculae were resected and broken, trypsinizated and washed completely by PBS. Bone surface and non-adhesive floating cells in cleaning fluid were observed with inverted microscope. Rib trabeculae was washed by DMEM culture medium once, and cultured in culture bottle. The culture liquid was replaced by new one once a week. The osteoblast was moved from the scledte a week later. The cells were fused monolayer and could be subcultured 4 to 6 weeks later. The active second or third generation cells were inoculated to 6-pore plate forming 5 groups. Osteoblast were stimulated by 5.6 mmol/L., 7.6 mmol/L, 9.6 mmol/L, 12.6 mmol/L, 20.6 mmol/L glucose medium respectively after the 80% cells were fused, the vitamin K_2 was added into the culture liquid until the concentration of it to be 10~(-5) mol/L. Supernatant was collected after half hour culturing, the undercarboxylated osteocalcin level were detected with RIA test kit, and corrected it as the total the undercarboxylated osteccalcin, calculated the carboxylated incomplete osteocalcin rate. RESULTS AND CONCLUSION: The rate of ostecblast carboxylated incomplete osteocalcin was different under different concentration glucose. The rate of 7.6 mmol/L, 9.6 mmol/L, 20.6 mmol/L concentration glucose groups were higher than that of 5.6 mmol/L glucose group [(0.27±0.02)%, (0.29±0.04)%, (0.12±0.02)%, P < 0.05]. It is indicated that osteoblast could sense the change of glucose concentration by regulating the secretion of the undercarboxylated osteocalcin between the concentration of 5.6mmol/L to 9.6mmol/L, while the carboxylated incomplete osteocalcin decreased as the concentration of glucose increased.

OBJECTIVETo study the relationship between cartilage end-plate calcification (CEC) and cervical intervertebral discs regression (CIDR) in rabbits, and to study the inhibitory effect of combined therapy of Kanggu Zengsheng Capsule (KZC) ansforming growth factor-apsule (TGF-PLC) and igene therapy (GT) on CEC by measuring the thickness of CEC layer.

METHODSThirty-five New Zeland rabbits of 4 months old were selected to establish cervical dynamic imbalance rabbit model for inducing CIDR (No disposal was given to rabbits in the normal control group). Seven months after operation, combined therapy of KZC and PLC were given, in doses calculated by body weight, to the modeled rabbits in the drug treated group with CEC of either superficial layer or full layer, twice a dantly by gavage for 30 successive days. While to those in the gene therapy group, the recombinant plasmid DNA with transforming growth factor-beta1 (TGF-beta1) was injected once their intervertebral discs (ID) of C(2-3) C(3-4) and C(4-5), 20 microl for each injection. One month later, all rabbits were sacrificed with periotic venous gas embolic method and their ID of C(4-5) (including partial body of the upper and lower vertebrae) was resected. The degree of CIDR was evaluated morphologically, and the thickness of CEC in rabbits was measured and compared between groups.

RESULTSThickness of CEC in the model group, either of superficial layer or of full layer, was significantly more than that in the normal control group with significant difference. Both combined KZC and PLC therapy and gene therapy showed significant inhibitory effects on CEC in treating CIDR (P < 0.05).

CONCLUSIONCEC is the initial factor of CIDR with highly positive correlation. Both combined therapy of KZC and PLC and gene therapy can significantly inhibit CEC.
