Objective To investigate the diagnositc value of high frequency ultrasound guided fine needle aspirates (FNA) and thyroglobulin (Tg) in fine-needle aspirate fluid (FNA-Tg) measurement for detecting metastatic lymph nodes in patients underwent thyroidectomy for papillary thyroid carcinoma (PTC).Methods Sixty-five patients with 79 suspected metastatic lymph nodes were retrospective analysis in this study.FNA for suspected lymph nodes was performed guided by high frequency ultrasound and FNATg was measured.The histopathologic diagnosis for all of the suspected lymph nodes was obtained after lymphadenectomy.Results By histopathologic diagnosis,62 lymph nodes were positive metastasis,while 17 were negative metastasis.Fifty-four lymph nodes were diagnosed as positive metastasis and 25 as negative metastasis by FNA.The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of FNA for assessing cervical metastatic lymph nodes from PTC were 89.87％ (71/79),87.10％ (54/62),100％ (17/17),100％ (54/54) and 68.00％ (17/25),respectively.Sixty-five lymph nodes were diagnosed as positive metastasis and 14 as negative metastasis by FNA-Tg.The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of FNA-Tg were 96.20％ (76/79),100％ (62/62),82.35％ (14/17),95.38％ (62/65) and 100％ (14/14),respectively.There was no significant difference between FNA and FNA-Tg for evaluating cervical metastatic lymph nodes from PTC (x2 =1.454,P =0.228).Eight positive metastatic lymph nodes which were missed by FNA were corrected diagnosed by FNA-Tg measurement.Conclusions Both FNA and FNA-Tg are effective methods for assessing cervical metastatic lymph nodes from PTC postoperatively,and these two methods could be combined for early and accurate evaluating the lymph nodes state.

OBJECTIVE:To systematically review the effect of organic cation transporter 2 [(OCT2)808G>T] gene polymor-phism on the metformin hydrochloride pharmacokinetics in vivo,and to provide evidence-based reference for clinical medication. METHODS:Retrieved from PubMed,EMBase,Foreign Medical Journey Service,CJFD,VIP database and Wanfang database,re-lated studies about the effect of (OCT2)808G>T gene polymorphism on the metformin hydrochloride pharmacokinetics in vivo were collected,and Meta-analysis was performed by using Rev Man 5.1 statistics software. RESULTS:A total of 5 retrospective studies were included,involving 172 patients. The result of gene type was type GT,type TT and type GG. Results of Meta-analysis showed,compared with type GT volunteers,type TT could prolong the half-time period of metformin hydrochloride;compared with type TT,type GG could increase the peak concentration. However,(OCT2)808G>T gene polymorphism had no effects on the renal clearance rate,creatinine clearance rate and area under the drug-time curve. CONCLUSIONS:(OCT2)808G>T gene poly-morphism has certain effect on the half-time period and peak concentration of metformin hydrochloride in vivo of health volunteer, and has no effect on the renal clearance rate,creatinine clearance rate and area under the drug-time curve. Due to the limit of re-search methodological quality,large-scale and high quality studies are required for further validation of the conclusions.

BACKGROUND:The greatest risk of osteoporosis in total knee arthroplastyisperioperative and long-term periprosthetic fractures. However, limited by the traditional concept of osteoarthritis patientswhousualy not associated with osteoporosis, domestic clinical trials have not given enough attention to the osteoporosis before total knee arthroplasty.
OBJECTIVE:To analyze the osteoporosis and its relative factors in osteoarthritis patients before total knee arthroplasty.
METHODS:Data of 81 cases (81 knees) of knee osteoarthritiswhounderwenttotal knee arthroplasty in the Department of Joint Surgery of Tianjin People’s Hospital from January 2012 to November 2014 were retrospectively analyzed. They received lumbar spine and hip bone mineral density examination before surgery. The correlation of bone mineral density with age, body mass index, knee motion range,and knee deformity was analyzed before surgery. The independent risk factors for osteoporosis before replacement were analyzed.
RESULTS AND CONCLUSION:(1) Of 81 patients, there were normal bone mineral density in 25 cases (31%), osteopenia in 35 cases (43%),andosteoporosis in 21 cases (26%). Al 10 males had no osteoporosis and 21 in 71 female cases suffered osteoporosis (30%). Theincidence of osteoporosis in females was significantly higher than in male patients (P=0.046). (2) There was a linear correlation of bone mineral density with age and body mass index (correlation coefficientr=-0.230, 0.225). (3) The age of≥65 years and body mass index≥25 kg/m2were independent risk factors of osteoporosis before replacement (P< 0.05). (4) Patients with knee osteoarthritis had higher incidence of osteopenia and osteoporosis before total knee arthroplasty. The degree of osteoporosis was negatively correlated with age, but positively correlated with body mass index. The age of≥65 years and body mass index < 25 kg/m2were independent risk factors for preoperative osteoporosis. Thus, bone mineral density examination is essential for those patients before total knee arthroplasty.

Objective To establish an animal model of annulus fibrosus (AF) partial defect for the repairing of interver?tebral disc (IVD) defect. Methods Image J 1.46r software was used to measure the T12/L1-L6/S1 intervertebral height in ovine lumbar spine X-ray films. AF thickness was measured by axial split disc. A 11 blade was used to make a trapezoid de?fect of upper bottom 3 mm, lower bottom 5 mm, height 5 mm and thickness 3 mm, whose lower bottom toward the nucleus pulposus (NP) in the left front of ovine lumbar IVD in vitro. The minimally invasive lateral approach was used to make the same type of trapezoid defect in the left front of the ovine lumbar IVD in vivo. The trapezoidal defect length of the axial divid?ing disc was measured, AF and a small amount of NP from trapezoidal defect in IVD were weighed, and the production of trapezoidal defect in IVD was evaluated. Results The lumbar intervertebral space height of ovine was (4.45 ± 0.28) mm. There were significant differences in the thickness of AF (4.08±0.50) mm , thickness (3 mm) and height (5 mm) of trapezoidal defect (P<0.05), respectively. There were no significant differences in trapezoidal defects in ovine lumbar IVD in vitro on the upper bottom (3.03 ± 0.09)mm, the lower bottom (5.03 ± 0.09) mm, the height (4.97 ± 0.10) mm, the thickness(3.02 ± 0.06) mm and the trapezoidal defect predetermined value on the upper bottom 3 mm, the lower bottom 5 mm, the height 5 mm and the thickness 3 mm (P>0. 05). The weights of the AF and NP taken out from ovine lumbar IVD in vitro and in vivo were (0.162 ± 0.011) g and (0.166 ± 0.014) g, and there was no significant difference between them (P > 0.05). Conclusion Through the operation of minimally invasive lateral approach, the method of making a trapezoidal defect in the experiments can establish animal model of AF partial defect, which meets the requirements for the repairing of IVD defect, and is simple, safe and reliable.

Objective To assess the prospect of integrated biphasic silk fibroin scaffold made by annulus fibrosus-nu?cleus pulposus tissue engineering in application as integrated intervertebral disc(IVD). Methods An integrated annulus fi brosus-nucleus pulposus(AF-NP)biphasic scaffold was made by silk fi broin using two different uncomplicated methods which were paraffin spheres-leaching method(outer AF phase)and phase separation method(inner NP phase). The scaf?fold was investigated by general observation, stereomicroscope and scanning electron microscopy(SEM). Its pore size, poros?ity, and compressive elastic modulus were determined. AF and NP cells were isolated from rabbit IVD and seeded into the corresponding phase of the scaffold respectively. The cell-scaffold complex was cultured for 48 hours. The biocompatibility of the scaffold was evaluated by SEM, live/dead staining while CCK-8 assay was used to assess cell proliferation. Results Stereomicroscope and SEM showed that AF phase and NP phase integrated perfectly without cross-linking. Both phases pos?sessed highly interconnected porous structure [pore size of AF and NP phase were(220.0±23.1)μm and(90.0±17.8)μm, re?spectively] and highly porosity(AF and NP phase were respectively 91%and 93%). In addition, this silk biphasic scaffold had impressive mechanical properties(150.7 ± 6.8)kPa. SEM revealed that disc cells attached to regions of pore walls, dis?tributed uniformly and secreted extracellular matrix. Live/Dead staining and cell count kit-8(CCK-8)analysis showed that the silk composite scaffold was non-cytotoxic to disc cells. Conclusion This silk biphasic AF-NP scaffold has satisfied pore size, porosity, biomechanical properties and biocompatibility, so it is ideal candidate for IVD tissue engineering.

Objective:To investigate the clinical value of monitoring serum complement C1q/tumor necrosis factors-associated protein 3 (CTRP3) and lipoprotein-associated phospholipase A2(Lp-PLA2) levels in patients with coronary heart disease, especially patients with acute myocardial infarction (AMI).Methods:This case-control study included 99 patients with angina pectoris aged (60.4±10.4) years, 105 patients with AMI aged (61.7±14.3) years, and 60 healthy individuals aged (43.6±9.5) years. Serum CTRP3 was detected by ELISA, and Lp-PLA2 was detected by automatic biochemical analyzer. Logistic regression analysis was performed to determine the correlation between CTRP3, Lp-PLA2 in angina pectoris and AMI patients. The diagnostic efficiency of each index was analyzed by receiver operating characteristic (ROC) curve.Results:Serum Lp-PLA2 was significantly higher in AMI group than in angina pectoris group ([313.1±68.1] U/L vs [205.8±71.4] U/L, P<0.001), while CTRP3 was significantly lower in AMI group than in angina pectoris group ([64.2±18.5] μg/L vs [84.8±25.0] μg/L, P<0.001). Logistic regression showed that serum CTRP3 was negatively correlated with AMI ( OR=0.964, 95% CI 0.935-0.993, P=0.019), and Lp-PLA2 was positively correlated with AMI ( OR=1.020, 95% CI 1.008-1.032, P=0.001). ROC analysis showed that the AUC (95% CI) of AMI diagnosed by CTRP3 was 0.753 (0.685-0.821), P<0.001; the AUC (95% CI) of AMI diagnosed by Lp-PLA2 was 0.884 (0.833-0.935), P<0.001; the AUC (95% CI) of diagnosis efficacy by combined indices was 0.910 (0.870-0.950), P<0.001. Conclusions:Lower serum CTRP3 and higher serum Lp-PLA2 levels are associated with increased risk for AMI. Combined detection of both indices can improve the diagnostic efficacy of AMI.
