This investigation is to explore the feasibility of applying reverse docking method to the selectivity studies of protein kinase inhibitors. Firstly, a database that consists of 422 protein kinase structures was established through collecting the reported crystal structures or homology modeling. Then a reverse docking based method of protein kinase target screening was established, followed by the optimization of related parameters and scoring functions. Finally, seven typical selective kinase inhibitors were used to test the established method. The results show that the selective targets of these inhibitors have relatively high scoring function values (ranking in the first 35% of the tested kinase targets according to the scoring function values). This implies that the reverse docking method can be applied to the virtual screening of kinase targets and further to the selectivity studies of protein kinase inhibitors.

The implantation of an intravascular stent has become a widely used minimally invasive treatment for coronary heart diseases due to its minimal invasiveness and high efficiency.But the long-term outcomes are often compromised by in-stent restenosis (ISR),which severely restricts its practical effectiveness.In this paper,the formation mechanism of ISR was discussed,and the effects of mechanical environment on ISR were analyzed from the view of solid mechanics.The research progress of stent expansion in vessels with 4 different shapes,including straight vessel,tapered vessel,bifurcation vessel and curved vessel was reviewed.Moreover,the correlations between vessel stress and vessel shape change caused by stent expansion and ISR were reviewed.Finally,based on the influence of different vessel shapes on stent expansion,a multi-objective optimization design method was proposed to improve the stent expansion performance and reduce the occurrence of ISR.

Objective To study the effects of rapamycin on cell growth and cell cycle in CNE-1 and CNE-2 cells. Methods Growth inhibition effect of rapamycin on CNE-1 and CNE-2 cells were assessed by cell counting kit-8 (CCK-8) assay. Morphological alterations of the cells were observed by microscope. Cell cycle and cell apoptosis were analyzed by FCM. The expression of mammalian target of rapamycin (mTOR)was analyzed by reverse transcription-polymerase chain reaction(RT-PCR). Results The growth of CNE-1and CNE-2 cells was inhibited significantly by rapamycin dose-dependently. FCM showed that CNE-1 and CNE-2 cells at 48 hours after rapamycin ( 150 nmoL/L) treatment were arrested in the G0/G1 phase of cell cycle. However rapamycin treatment did not significantly induce apoptosis of CNE-1 and CNE-2 cells (P ＞0. 05). RT-PCR showed that rapamycin significantly inhibited mRNA expression of mTOR in CNE-2 cells (t = 10. 625 ,P ＜ 0. 01 ). Conclusions Rapamycin inhibits the growth of CNE-1 and CNE-2 cells by inhibiting the progression of cell cycle, which could be achieved through decreaseing the expression of mTOR.

Objectives We sought to determine the factors that predicted in-hospital heart failure(HF)in patients undergoing successful primary percutaneous coronary intervention(PCI)for ST-segment elevation myocardial infarction(STEMI). Methods The clinical and angiographic data were retrospectively reviewed in patients undergoing successful primary PCI for their ifrst STEMI. According to the occurrence of in-hospital HF, patients were divided into HF group and non-HF group. The incidence and predictors of in-hospital HF and its impact on prognosis were determined. Results A total of 834 patients were included, among them 94 patients (11.3%) were in the HF group and 740 patients(88.7%) were in the non-HF group. The mean age was (62.9±12.9) years and 662 patients (79.4%) were male. All-cause mortality at 30 days was signiifcantly higher in the HF group than in the non-HF group (24.5%vs. 1.5%, P<0.001). In Cox regression analysis, left anterior descending artery (LAD) as the culprit vessel (HR 2.173, 95% CI 1.12~4.212, P=0.022), ln 24 h NT-proBNP (HR 1.904, 95%CI 1.479~2.452, P<0.001), 24 h hsCRP≥11.0 mg/L (median) (HR 2.901, 95%CI 1.309~6.430, P=0.009) and baseline serum glucose (HR 1.022, 95%CI 1.000 ~ 1.044, P=0.046) were independent predictors of in-hospital HF. Receiver operator characteristic analysis identiifed 24 h NT-proBNP ≥ 1171 pg/ml (c=0.883, P < 0.001) and 24 h hsCRP ≥ 13.5 mg/L (c=0.829, P < 0.001) were the best cut-off values in discriminating in-hospital HF with a sensitivity and speciifcity of 92.5%and 76.8%for 24 h NT-proBNP, 86.0%and 77.0%for 24 h hsCRP, respectively. Even among patients with LAD as the culprit vessel, the incidence of in-hospital HF was only 0.4%in patients whose 24 h NT-proBNP was<1171 pg/ml and 24 h hsCRP was<13.5 mg/L;while the incidence of in-hospital HF was up to 60.9%in patients whose 24 h NT-proBNP≥1171 pg/ml and 24 h hsCRP≥13.5 mg/L (P<0.001). Conclusions The incidence of in-hospital HF was still high in STEMI patients even after successful primary PCI. Patients with in-hospital HF had poor prognosis. LAD as the culprit vessel, hsCRP, NT-proBNP and baseline serum glucose were independent predictors of in-hospital HF. Assessment and combined use of different serum biomarkers were effective methods to estimate the risk of in-hospital HF in STEMI patients undergoing primary PCI.

OBJECTIVETo explore the feasibility and safety of transtracheal assisted sublingual approach to totally endoscopic thyroidectomy by studying the anatomical approach and adjacent structures.

METHODSA total of 5 embalmed adult cadavers from Chengdu Medical College were dissected layer by layer in the cervical region, pharyngeal region, and mandible region, according to transtracheal assisted sublingual approach that was verified from the anatomical approach and planes. A total of 15 embalmed adult cadavers were dissected by arterial vascular casting technique, imaging scanning technique, and thin layer cryotomy. Then the vessel and anatomical structures of thyroid surgical region were analyzed qualitatively and quantitatively. Three-dimensional visualization of larynx artery was reconstructed by Autodesk 3ds Max 2010(32). Transtracheal assisted sublingual approach for totally endoscopic thyroidectomy was simulated on 5 embalmed adult cadavers.

RESULTSThe sublingual observed access was located in the middle of sublingual region. The geniohyoid muscle, mylohyoid seam, and submental triangle were divided in turn in the middle to reach the plane under the plastima muscles. Superficial cervical fascia, anterior body of hyoid bone, and infrahyoid muscles were passed in sequence to reach thyroid gland surgical region. The transtracheal operational access was placed from the cavitas oris propria, isthmus faucium, subepiglottic region, laryngeal pharynx, and intermediate laryngeal cavit, and then passed from the top down in order to reach pars cervicalis tracheae where a sagittal incision was made in the anterior wall of cartilagines tracheales to reach a ascertained surgical region.

CONCLUSIONTranstracheal assisted sublingual approach to totally endoscopic thyroidectomy is anatomically feasible and safe and can be useful in thyroid gland surgery.

OBJECTIVETo explore the satisfactory rate in patients with body dysmorphic disorder (BDD) after cosmetic surgery.

METHODSWe designed a questionnaire to investigate the postoperative satisfactory rate in patients with BDD and without BDD.

RESULTSThere was significant difference in postoperative satisfactory rate between patients with BDD and without BDD.

CONCLUSIONThe patients with BDD have a lower satisfactory rate, which is even worse after repeated surgery.
