Objective To explore the diagnostic value of ultrasound in thyroid nodular disease.Methods Eighty-seven patients with thyroid nodule in hospital from 2010-2011 were taken ultrasound examination,including 23 cases with benign nodules and 64 cases with malignant nodules.Univariate analysis and mutivariate Logistic regression analysis were taken to test the ultrasonic index (internal echo,boundary,size,shape,microcalcifications,and aspect ratio) for discovery of the best diagnostic ultrasonic index to identify benign and malignant nodules.Results The ultrasound in the patients with malignant thyroid nodules showed the hypoecho,unclear border,irregular shape,microcalcifications,low blood supply,the aspect ratio ＞ 1.The ultrasound in the patients with benign thyroid nodules showed high or equal echo,clear border,regular shape,high blood supply,and the aspect ratio≤ 1.The ultrasonic indices between two groups had statistically significant difference (P ＜ 0.05).The shape and microcalcifications were the best ultrasonic diagnostic index to indentify the benign and malignant nodules with an EXP(B) 20.12 and 19.14,respectively.Conclusions The ultrasound is helpful in the diagnosis of thyroid nodular disease and identification of benign and malignant thyroid nodules.The ultrasonic images are the basic data for the clinical diagnosis of thyroid nodules.

Objective To examine the impact of C-reactive protein (CRP) on the expression of interleukin-6 (IL-6), inflammatory cytokine, in cultured human pulmonary artery smooth muscle cells (hPASMCs) in order to find out the cause of pulmonary artery hypertension (PAH). Method The hPASMCs were cultured and stimulated by different concerntrations of CRP (5 - 200 μg/ml) for different lengths of time. The activity of nuclear factor-κB (NF-κB) was evaluated by electrophoretic gel mobility shift assay (EMSA). The expression of IL-6 mRNA and the level of IL-6 protein were measured by using real-time PCR and ELISA, respectively. Results CRP increased IL-6 production in hPASMCs in a dose-dependent manner. The increase in IL-6 at concerntration of 200 μg/mL in the CRP group was as high as 2.8times that in the control group. CRP also significantly induced the activation of NF-κB in hPASMCs. The effect of CRP on the inflammatory cytokine, IL-6, was inhibited by the specific FcγⅡa receptor antibody.Conclusions In vitro, CRP increases the production of IL-6 in hPASMCs mediated by FcγⅡa receptor and NF-κB translocation. These data offer important insights into the role of CRP in the pathogenesis of PAH.

Animal models of pulmonary artery hypertension (PAH),aiming to simulate human characteristics of the disease,have contributed extensively to understanding the pathophysiology of PAH and the investigation of experimental treatments.The classical models include monocrotaline models,chronic hypoxia model and so on,more new models were investigated in recent years.These animal models were not able to perfectly mimic human pathological characteristics of PAH because of the defect in different aspects.In this review,both typical and novel methods of PAH modeling were summarized and evaluated to provide a suitable guidance for the settlement of animal models which can meet human characteristics comprehensively.

Objective To investigate the protective effects and molecular mechanism of peroxisome proliferate-activated receptor α(PPARα) activation on acute myocardial damage induced by isoproterenol (Iso) in rats. Methods Thirty male Wistar rats, weighting 160～180 g, were randomly divided into control group, Iso group, fenafibrate(FF) group(each n=10) according to physique quantity. Acute myocardial injury caused by Iso abdomen cavity injection induced ischemia was established and the protective effects of peroxisome proliferate-activated receptor α activation were accessed by the level of ereatine kinase(CK), lactic dehydrogenase(LDH) in serum as well as the activities of myoperoxidase(MPO) in myocardium, and the protein expressions of PPABα in myocardium by Western blot. Results The level of serum CK in control group, lso group and FF group, was (62.41±9.47),(101.71±11.05),(75.64±11.73)kU/L, respectively(F= 34.34, P<0.01). Whereas the level of serum CK in Iso group and FF group was higher than that in control group(P<0.01 or<0.05), the level of serum CK in FF group was lower than that in Iso group(P<0.01). The levels of LDH in these three groups were (5912.20±204.44), (6365.78±137.10), (6089.76±169.60) U/L, respectively(F= 17.54, P<0.01). Compared with the control group, the levels of LDH in Iso and Fir groups were significantly increased(P<0.01 or<0.05). But the level of LDH in FIr group was decreased compared with that in Iso group(P<0.01). The activities of myocardial MPO in these three groups were (1.95±0.10),(3.89±0.17),(2.49±0.19)U/g, espectively(F=391.68,P< 0.01). The activities of myocardial MPO in Iso and FF groups were higher than that in the control group (all P< 0.01), while the activities of myocardial MPO in FIr group were lower than that in lso group(P<0.01). The protein expressions of PPARα in myocardium of these three groups were 251.57±10.95,191.97±10.74,215.08±9.61, respectively(F=82.69, P<0.01). Conclusion PPARα activation by its actor FF can exert protective effects on the acute myocardial ischemia injury induced by lso in rats through inhibiting the release of inflammatory cell factors.

The aim of this study was to investigate and evaluate the antitumor effects of a novel poly(ADP-ribose) polymerase (PARP) 1/2 inhibitor, YHP-836, in combination with temozolomide (TMZ) for the treatment of glioblastoma (GBM). The cytotoxicity of YHP-836 was tested alone or in combination with TMZ using MTT assay. Immunoblotting and flow cytometry were also employed to assess the combination activity of YHP-836 and TMZ in multiply GBM cell lines. Further, the antitumor activity of YHP-836 and TMZ was evaluated using subcutaneous and orthotopic mice xenograft tumor models. All procedures were approved by the Ethics Committee for Animal Experiments of the Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College and conducted under the Guidelines for Animal Experiments of Peking Union Medical College. The approval number is 00009138. It was demonstrated that the combination of YHP-836 and TMZ increased the cytotoxicity against GBM cells and upregulated histone H2AX phosphorylation (γH2AX) expression levels compared to TMZ treatment alone. The combination also led to the S-phase cell cycle arrest. Moreover, YHP-836 significantly enhanced TMZ antitumor effects without significantly increasing chemotherapy drug toxicity in vivo, whereas YHP-836 alone showed limited therapeutic efficacy against GBM. In conclusion, the novel PARP1/2 inhibitor, YHP-836, sensitizes TMZ and provides a basis for further investigation into its mechanism of action. These findings suggest that YHP-836 may be a potential candidate for combination therapy with TMZ in patients with TMZ resistance.

OBJECTIVETo compare therapeutic effects of locking plates for the treatment of Neer 3-and 4-part proximal humerus fractures.

METHODSFrom January 2009 to June 2011, 64 patients with Neer 3-and 4-part proximal humerus fractures were treated with locked plate fixation. There were 39 patients in the 3-part group including 16 males and 23 females, with an average age of (55.12 +/- 12.52) years old; and 25 patients in the 4-part fractures group including 9 males and 16 females,with an average age of (57.92 +/- 13.14) years old. The American Shoulder and Elbow Surgeons score (ASES), visual analogue scale (VAS) and complications were documented for analysis before and after treatment.

RESULTSAll the patients had incision healing at the first stage. All the patients were followed up, and the duration ranged from 12 to 30 months, with a mean of 16.5 months. Comparably better shoulder function recovery was achieved in the 3-part fractures group with regard to the ASES (76.14 +/- 14.10 in the 3-part fractures group vs. 65.93 +/- 11.82 in the 4-part fractures group, P < 0.05). Moreover,a statistical difference (P < 0.05) was observed regarding the VAS pain score (2.12 +/- 1.63 in the 3-part fractures group vs. 3.90 +/- 2.21 in the 4-part fractures group). For the complications rate,no statistical difference was noted between 3-part fractures group and 4-part fractures group (20.51% vs. 36.00%).

CONCLUSIONThe clinical outcomes of the 3-part proximal humerus fractures is better than the 4-part fractures proximal humerus fractures treated with locking plate. Complex proximal humeral fractures treated with locking plates can be achieved a satisfactory outcome when attention is paid to anatomic reduction, stable fixation, proper screws and plate placement, and reasonable functional exercise postoperative.
