Objective To evaluate the safe ty and efficacy of CT-guided percuta neous ethanol injection (CT-PEI) in the treatment of thyroid adenoma. M ethods Fifty-four patients with 73 nodules were included in the study. Thyroi d adenoma was confirmed by pathology. The serum level T3, T4, and TSH were norma l in all cases. CT-PEI (0.3-2.5 ml ethanol/cm~3 nodular tissue) was given for 115 times (mean 1.58?078 times/nodule). Results Complete cu re was observed in 37 nodules (50.7%). In 28 nodules (38.3%) volume reduction was greater than 80%. A significant nodule reduction (50%-80%) was observed in 7 nodules. Only 1 (1. 4%) nodule volume reduction was 28.9%. Apart from 1 case of transient dysphonia and 2 cases of mild pain and burning sensation, no side effect was observed. Conclusion CT-PEI is a safe and effective therapeutic procedure with f ew side effects for thyroid adenoma.

[Objective]To study the repair of articular cartilage defects with combined bone morphogenetic protein(BMP)/basic fibroblast growth factor(bFGF)biomaterial in order to supply experimental basis for repairing cartilage defects biologically.[Method]Twenty-four 14-week-old rabbits were randomly divided into four groups,BMP/bFGF biomaterial gel(group A),BMP biomaterial gel(group B),bFGF biomaterial gel(group C)and simple fibrin glue treated group(group D).A couple of knees of each rabbit experienced 5 mm-diameter-full cartilage resection and drilling throuth of bone marrow.Gross appearance,histologicol section and electron microscope were axamined at 8,12,24 weeks after operation.[Result]In group A the cartilage defects were smoothly repaired by white translucent hard tissue at 8 and 12 weeks,and defect boundary was hard to be indentified with normal cartilage at 24 weks.No smooth repairing was observered in B,C and D groups.Group A got a better histological score than B,C and group D(P0.05).[Conclusion]Combined BMP/bFGF biomaterial is good for repair of articular cartilage defects and has better result than using BMP or bFGF alone.These results may provide a therapy for articular cartilage defects.

Objective To explore the relationship between platelet to lymphocyte ratio (PLR) and microangiopathyin type 2 diabetes mellitus. Methods In this case-control study, the clinical data on 428 adult patients with type 2 diabetic microangiopathy in our hospital from January 2009 to December 2015 were retrospectively analyzed. PLR, age, sex, fasting blood glucose, glycosylated hemoglobin, total cholesterol and triglyceride were tested to investigate their relationship with type 2 diabetic microangiopathy. Results Logistic regression analysis showed that PLR was a risk factor of type 2 diabetic microangiopathy (OR = 3.162, 95%CI:1.556 ~ 7.421, P < 0.05). Conclusions Greater PLR is closely related to type 2 diabetic microangiopathy, and we should pay attention to type 2 diabetic microangiopathy with a greater PLR in clinical practice.

ObjectiveTo investigate the preventive effects of rosiglitazone on nonalcoholic steatohepatitis (NASH) rats and to explore the potential mechanisms in modulating peroxisome proliferator-activated receptor gamma (PPARγ),nuclear factor kappa B (NF-κB),and cyclooxygenase-2 (COX-2) expression.Methods Thirty male SD rats were assigned into the normal group ( n =10),the model group ( n =10),rosiglitazone prevention group [ n =10,simultaneously 4mg/( kg · d) gavage daily at beginning].Liver appearance,liver index,and histological changes were assessed.Serum tumor necrosis factor-o (TNF-c) and prostaglandin E2 (PGE2) were determined using enzyme-linked immunosorbent assay.The expressions of PPARγ,NF-κB,and COX-2 in liver were determined using immunohistochemical methods.The mRNA and protein expressions of COX-2 were disclosed by real-time polymerase chain reaction and Western blot analysis.ResultsCompared with the normal group,the liver index significantly increased in model group (3.92 ±0.72 vs.5.71 ± 1.05,P =0.004).HE and Masson staining showed significantly increased steatosis,inflammation,and fibrosis.The serum levels of TNF-α,PGE2 in high-fat-diet-fed rats were significantly increased ( 11.72 ± 2.47 vs.29.39 ± 5.32,P =0.002 ; 236.60 ± 24.90vs.288.24 ± 17.17,P =0.004).Immunohistochemistry showed NF-κB and COX-2 in livers were significantly elevated,but PPARγ wasdecreased in nonalcoholic steatohepatitis rats.Real-time polymerase chain reaction and Western blot found mRNA and protein expressions of COX-2 were increased in the model group (0.57 ± 0.08 vs.2.83 ± 0.24,P =0.0007 ; 0.38 ± 0.03 vs.1.00 ± 0.03,P =0.004).Compared with the model group,the expressions of PPARγsignificantly increased and the expressions of NF-κB and COX-2 significantly decreased ( mRNA:2.83 ± 0.24 vs.0.46 ± 0.11,P =0.002 ; protein: 1.00 ± 0.03 vs.0.62 ± 0.02,P =0.006 ) in the rosiglitazone prevention group.ConclusionBy inhibiting NF-κB and COX-2 expressions,rosiglitazone can reduce insulin resistance and then prevent the occurrence and deve lopment of nonalcoholic steatohepatitis.

Objective To evaluate the impact of rosiglitazone (Ros) on liver expression of peroxisome proliferator-activated receptor γ (PPARγ),nuclear factor (NF-κB) and cyclooxygenase-2(COX-2) in treatment of nonalcoholic steatohepatitis (NASH) rats.Methods Thirty Sprague-Dawley rats were divided into normal group,model group and Ros treated group with 10 each.Except the normal group,the other two groups were given high fat diet for 12 weeks for NASH model.The rats in Ros treated group were gavaged 4 mg/kg of Ros daily at the 12th week for 8 weeks.All rats were sacrificed at the 20th week for blood sample and liver tissue.Biochemical parameters of liver function,lipid metabolism,glycometabolism and antioxidant enzyme activities were measured.The histological change of the liver were assessed with HE and Masson staining.The level of tumor necrosis factor (TNF)-α and prostaglandin E2 (PGE2) was measured using ELISA.The expression of PPARγ,NF-κB and COX-2 was detected with immunohistochemistry.The mRNA and protein expressions of COX-2 were tested by real-time PCR and Western blotting,respectively.Results In comparison with model group,Ros treated group showed significant improvement in hepatic steatosis,inflammation and fibrosis(all P value<0.05).In model group,the serum levels of fasting blood glucose,insulin and HOMA-insulin resistance index (HOMA-IRI),total cholesterol (TC),total triglyeride (TG),lowdensity lipoprotein cholesterol (LDL-C) and free fatty acids were increased,but HDL-C level was decreased.All above parameters markedly improved after Ros treatment.The levels of ALT and AST,total anti-oxidation competence,superoxide dismutase,catalase,glutathione peroxidase and malondialdehyde in Ros treated group were significantly ameliorated when compared with those in model group.Immunohistochemistry showed that the expression of NF-κB and COX-2 was significantly elevated,but PPARγ was decreased in model group.Real-time PCR and Western blot revealed that the mRNA and protein expressions of COX-2 were higher in the model group than those in normal group (0.57±0.08 vs 0.38±0.03;2.83±0.24 vs 1.00±0.03,P=0.000 and P=0.004,respectively),but significantly lower in Ros treated group (0.55±0.06 and 1.84±0.13,P<0.01).Conclusions Ros can reduce oxidative stress and insulin resistance in NASH rats by activing PPARγ expression and inhibiting expression of NF-κB and cyclooxygenases.

Objective To investigate the effects of icarrin on the activity and protein expression of core binding factor otl(Cbfa1) in rat osteoblasts cultured in vitro,and to explore whether mitogen-activated protein kinase (MAPK) pathway is involved in this process.Methods Calvarial osteoblasts were obtained from newborn (<24 h) SD rats by trypsin-coUagenase digestion method.The second generation osteoblasts were cultured in the medium containing icariin (10 ng/ml) or estradiol (10-8 mol/L) with or without extracellular-signal regulated kinase (ERK) inhibitor (UO126) or p38MAPK inhibitor (SB203580).Nuclear protein was extracted from osteoblasts.And then the activity of Cbfa1 was detected by ELISA.The amounts of Cbfa1 protein were detected by Western blot.Results Calvarial osteoblasts were obtained successfully and were used in this study after indentified by alkaline phosphatase and mineralized nodus staining.Cbfa1 expression and the activity in osteoblasts were up-regulated by both icariin and estradiol (P<0.05).The effects were partly inhibited by addition of U0126or SB203580 (P<0.05).Conclusions Either icarrin or estradiol can stimulate the proliferation and maturation of cultured osteoblasts in vitro via up-regulating the activity and expression of Cbfal.The MAPK signal pathway inhibitor seems to partly decrease Cbfa1 activity.It suggests that MAPK pathway may be involved in the transduction of icariin's impact on proliferation and mineralization of osteoblasts.

[Objective] To explore how to deal with the paternity test of complex adoption cases. [Method] Samples from 13 families, in which adoptive parents were suspected related to biological parents, were genotyped using "Identifder + Sinofder + Powerplex 16" combined system (D8S1179, D21S11, D7S820, CSFIPO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818, FGA, D6S1043, D12S391, PentaD, PentaE) followed by further statistical analysis. [Result] Among all 13 cases, 2 were completely accordance with the Mendel law, PI > 10 000. There found more than 3 inconsistent loci in 8 cases. And found 1～2 inconsistent loci in 3 cases, needed to test more STR loci until PI≥10 000. The half sibling index (HSI) was also calculated with ITO method. The adoptive parents of 2 cases were not excluded from a full sibling with biological parents. In addition, Y-STR loci were tested for 4 cases (father/son). Two adoptive fathers of them were not excluded from the paternal relationship with biological fathers. [Conclusion] The most (76.9%) of all (13) complex adoptive cases of paternity test could be drawn a definite conclusion with combined system of "Identifder + Sinefiler + Powerplexl6". Minority (23.1%) of them was not definite yet and needed testing more STIR loci. Meanwhile, we suggested adding Y-STR tests and providing HSI for reference.

ObjectiveTo investigate and compare the efficacy, safety, and cost effectiveness in the treatment of painful osteoporotic vertebral compression fractures ( OVCFs ) with percutaneous vertebroplasty (PVP) and kyphoplasty(PKP). MethodsSeventy-two patients (96 vertebrae) with painful OVCFs were treated by PVP (n ＝34) or PKP (n ＝38) under radiological monitoring. After bone biopsy needle into the compressed vertebra, bone cement (polymethylmethacrylate) was injected in PVP group, and that was inserted followed by the inflation of vertebra to create cavities in PKP group. The fluoroscopy time, total amount of bone cement injected, and cost were recollected respectively. The score of visual analogue scale point( VAS, 10-point scale)was determined at before the procedures, and 24 hours, one week, and one month after the procedures.Pain relief and complications were observed.The Cobb angle and vertebral heights of the anterior, middle, and posterior border were measured pre-and post-operative. ResultsThe two procedures were technically successful in all patients. The follow-up ranged from 1. 0 to 34. 0 months [mean time, (8. 9 ±3.2) months]. The Mean fluoroscopy time of treating per vertebra in PVP group was ( 11. 1 ± 10. 6 ) min, which was significant shorter than that ( 23.5 ± 13. 0) min in PKP group( P ＜0. 05 ).The mean total cost per patient was (5127. 2 ± 502.3 ) yuan in PVP group, which were strikingly lower than that(32 301.4 ±3204. 6) yuan in PKP group (P ＜0. 05).(3)There was no significant difference( P ＞0. 05 ) in average cement volumes in PVP group [ (4. 9 ± 1.1 ) ml]and PKP group [ (5.4 ± 1.7 ) ml]. Pain relief of was observed in 94. 1％ (32/34) of PVP group and in 92. 1％ (35/38) of PKP group. The score of VAS at pre-operation was (8. 3 ±0. 4 vs 7.9 ±0. 8) ,and at post-operative 24 h (2. 9 ±0. 9 vs 2. 8 ± 1. 2),1 week (2.6 ± 0. 9 vs 2.6 ± 1. 1 ), and 1 month (2.6 ± 0. 9 vs 2. 5 ± 1.3 ) were no difference at PKP and PVP group(P ＜0.05). There was significant difference between pre- and post-operative time point in each group. The Cobb angle, anterior and middle height of vertebra was corrected in both PVP and PKP group. In PVP group, the preoperative Cobb angle, anterior and middle height of vertebra was (24. 2 ± 3.8 )°,( 19. 1 ± 1.4) mm, (25. 2 ± 1.0) mm, which was significant different ( P ＜ 0. 05 ) from that of ( 19.4 ±3.9)°, (21.0 ± 1.5) mm, (27.0 ± 1.2) mm at pre-operation.In PKP group,there was significant difference (P ＜ 0. 05 ) in the preoperative Cobb angle, anterior and middle height of vertebra [(25. 1 ±5.0)°vs(10.7 ±2.8)°, (19.5 ± 1.5) mm vs (24.3 ± 1.9) mm, (25.4 ± 1.1) mm vs (29.7 ±1.3) mm, respectively]. As to the above index, the overall correcting effect in PKP was much better than that in PVP( P ＜0. 05 ). Cement leakage occurred in 9 cases in PVP group and 3 cases in PKP group ( P ＜0. 05 ) but no symptoms. There were no major complications during operation in the two groups. Conclusion PVP and PKP are effective and safe in the treatment of painful OVCFs but PVP is more cost effective than PKP.

Objective:To explore the effects of LncRNA HCG18 on endoplasmic reticulum stress and autophagy via regulating miR-185-5p/AGER axis in diabetic nephropathy (DN) .Methods:The kidney tissues of patients with DN were collected and the podocyte injury model induced by high glucose (HG) was established. The expression of HCG18 in renal tissue in DN patients and cell model was detected. The localization and expression of HCG18 in cells were determined. The regulatory relationship between HCG18 and miR-185-5p, miR-185-5p and AGER was testified. QRT-PCR and western blot were used to detect the expression of endoplasmic reticulum stress related factors (CHOP, XBP1) and autophagy related factors (Beclin-1, p62) .Results:Compared with non-DN patients, HCG18 was overexpressed in renal tissue of DN patients ( P<0.05) . Compared with normal glucose (NG) group, mRNA and protein expression of endoplasmic reticulum stress related factors (CHOP, XBP1) were overexpressed but mRNA and protein expression of autophagy related factors Beclin-1 were inhibited, p62 mRNA and protein expression were increased (all P<0.05) . HCG18 regulated the miR-185-5p/AGER axis and played a biological role. Knocking down of HCG18 reduced endoplasmic reticulum stress, activated autophagy and reduced podocyte injury, but this effect can be partially reversed by miR-185-5p inhibitors. Conclusion:HCG18 regulates the miR-185-5p/AGER signal axis and promotes DN progression through regulating endoplasmic reticulum stress and autophagy.
