Objective To elucidate the effect of multi-kinase inhibitor sorafenib on anaplastic thyroid carcinoma cells in the presence or absence of metformin.Methods SW1736 and C643 cells were treated with sorafenib in the presence or absence of metformin for various periods of time.Cell viability was detected by MTT.Cell cycle and cell apoptosis were measured by flow cytometry.Caspase-3 activity was detected by colorimetric kit.Western blot was used to analyze pERK phosphorylation and cyclinD1 expression.Results Sorafenib inhibited the growth of anaplastic thyroid carcinoma cells and induced cell cycle arrest and cell apoptosis.The EC50 of sorafenib in SW1736 and C643 was 3.68 μmol/L and 4.87 μmol/L respectively.After sorafenib ± metformin treatment,the caspase3 activity was 131.5 % and 278.0% (P<0.01) in SW1736 cells,127.2% and 196.6% (P<0.01) in C643 cells.On the molecular level,sorafenib inhibited the phosphorylation of ERK and decreased the expression of cyclinD1.Metformin amplified the growth inhibitory effect of sorafenib on anaplastic thyroid carcinoma cells.The cell viability was 0.76 ± 0.17 and 0.30 ± 0.04 (P<0.01) in SW1736 cells,0.72 ± 0.09 and 0.34 ± 0.10 (P<0.001) in C643 cells after 2.5 μmol/L sorafenib without or with 5 mmol/L metformin treatment.Conclusions The combination of sorafenib and metformin may be a potent strategy for the treatment of anaplastic thyroid carcinoma and other advanced cancers.

Telomere maintenance plays a critical role in cancer progression.Approximately 85% human cancer cells maintain their telomere length through activation of telomerase.Other 15%of cancers maintain telomere length independently of telom-erase by alternative lengthening of telomeres (ALT)pathway. Both events are equally important for telomere length mainte-nance of cancer cells.Human telomere consists of a series of G rich DNA sequences,which could form G-quadruplex.The for-mation of this structure can block the extension of telomeres by telomerase or ALT,resulting in cancer cell death.Thereby,G-quadruplex has been one of the focuses of anticancer therapy in recent years.This review focuses on the latest progress of G-quadruplex stabilizers.

Objective To investigate the effect of 17β-estradiol on the proliferation of thyroid stem/ progenitor cells.Methods In thyroid stem/progenitor cells derived from nodular goiters,the effects of 17 β-estradiol on thyrosphere formation,estrogen receptor (ER) expression,cyclin D1 expression,and mitogen activated protein kinase (MPAK) pathway were analysed by BrdU ELISA,conventional and realtime PCR,immunofluorensence staining,and Western blot.Results 17β-estradiol induced thyrosphere formation and proliferation of thyroid stem/ progenitor cells.ER-α and ER-β were expressed in thyroid stem and progenitor cells with higher mRNA expression level of ER-α compared to differentiated thyrocytes (8.85-±0.81 vs 1.10 ±0.35,P<0.01).Stimulation by 1 mmol/L 17β-estradiol increased cyclin D1 mRNA expression and ERK phosphorylation levels,which was blocked by an ER antagonist,ICI 182780.Conclusion Estrogen stimulated the growth of stem cells derived from thyroid nodules via estrogen receptor,suggesting the relevance of increased thyroid stem cell proliferation with higher prevalence of thyroid nodules in women.

Objective To explore the relationship between adipocyte fatty acid binding protein (A-FABP) and lower limb vascular disease (LLVD) in the elderly with type 2 diabetes(T2DM).Methods Bilateral lower limb vessels were checked by the High Resolution Color Doppler in all the subjects,including 40 healthy subjects as control (group A),126 T2DM patients.42 T2DM patients had no LLVD (group B),40 had mild LLVD (group C),and 44 had severe LLVD (group D).The levels of plasma A-FABP,blood glucose,lipid profiles,HOMA-IR,hypersensitive C reactive protein (hs CRP),and e-glomerular filtration rate were determined.Results The levels of plasma A-FABP were in the following ascending order of group A(4.5± 1.7)μg/L<group B(6.1±2.1)μg/L<group C (7.2 ± 2.3)μg/L < group D (8.4 ± 3.2)μg/L (P< 0.01).A-FABP levels elevated along with the decrease of ABI and the increase of L IMT.Multiple logistic regression analysis showed that A FABP levels was main influencing factor of lower limb vascular disease (LLVD) in the elderly with type 2 diabetes.LDL C,HbA1c,HOMR-IR,hs-CRP were the predictive factors for the plasma A-FABP levels in the elderly with T2DM after multiple stepwise regression analysis.Conclusions For elder T2DM patients,the level of plasma A FABP is correlated with the degree of LLVD,and plays an important role in the progress of LLVD.

In this paper, optimization of the conditions of microwave technique in extraction process of Guizhi Fuling capsule in the condition of a pilot scale was carried out. First of all, through the single factor experiment investigation of various factors, the overall impact tendency and range of each factor were determined. Secondly, L9 (3(4)) orthogonal test optimization was used, and the contents of gallic acid in liquid, paeoniflorin, benzoic acid, cinnamic acid, benzoyl paeoniflorin, amygdalin of the liquid medicine were detected. The extraction rate and comprehensive evaluation were calculated with the extraction effect, as the judgment basis. Theoptimum extraction process of Guizhi Fuling capsule by microwave technology was as follows: the ratio of liquid to solid was 6: 1 added to drinking water, the microwave power was 6 kW, extraction time was 20 min for 3 times. The process of the three batch of amplification through verification, the results are stable, and compared with conventional water extraction has the advantages of energy saving, time saving, high efficiency advantages. The above results show the optimum extracting technology of high efficiency, stable and feasible.

OBJECTIVETo explore the operation methods and clinical effects of transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament in treating complete acromioclavicular joint dislocation.
METHODSFrom January 2006 to June 2012,26 patients with acute complete acromioclavicular joint dislocation underwent surgery. Transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional clavical hoot plate and Kirschner wires fixation, were performed in all the patients. Among the patients, 18 patients were male and 8 patients were female, with an average age of 36.7 years old (ranged from 25 to 51 years). The duration from injury to operation was from 3 to 12 days with an average of 5 days. According to the Rockwood classification, 4 cases were grade III and 22 cases were grade V . Clinical manifestation included local swelling, tenderness with snapping, limitation of shoulder joint motion. In preoperative bilateral shoulder joint X-rays, the injured coracoclavicular distance was (16.2 ± 5.0) mm which was significantly wider than that of uninjured sides (7.6 ± 1.0) mm. Clinical results were evaluated according to X-rays and Constant-Murley score.
RESULTSAll incisions obtained primary healing after operation without complication of infection, internal fixation breakage, redislocation. All the patients were followed up from 12 to 30 months with an average of 18 months. Kirschner wires and internal fixation plate were removed at 1 month and 8-10 months after operation, respectively. At final follow-up, the motion of shoulder joint recovered to normal and a no pain joint was obtained. According to Constant-Murley score, 24 cases got excellent results and 2 cases good. There was no significant difference after operation between the injured coracoclavicular distance and the uninjured contralateral side [(7.7 ± 1.2) mm vs (7.6 ± 1.0) mm), P > 0.05].
CONCLUSIONTransfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional fixation using hook plate and Kirschner wires is the effective surgical method in treating complete acute acromioclavicular joint dislocation.
