Objective:To investigate the pediatricians' needs in the contents of continuing medical education (CME), and the influencing factors of participating in CME, so as to provide references for improving their vocational ability.Methods:Questionnaire survey was carried out for the pediatricians from county-level medical institutions in the nine provinces of China. The questionnaire contents included: basic information, CME contents needs, and influencing factors of participating in CME. SPSS 22.0 was used for chi-square test.Results:A total of 465 questionnaires was recovered, among which 463 were qualified, with a pass rate of 99.6%. Research showed that ① In terms of competency training needs, pediatricians had higher training demand for ability of diagnosis and treatment of children's diseases, pediatrics basic skills and skills related to children's health care, etc. Pediatricians with junior or intermediate title had higher training demand for ability of self-learning and access to learning resources ( P < 0.01); and pediatricians with senior title had higher training demand for teaching ability ( P < 0.05). ② In terms of pediatrics specialty content training needs, pediatricians had higher demand for neonatology, infectious, respiratory, critical medicine, developmental behavior and digestion in order. ③ Regarding the influencing factors of CME, too few opportunities to participate in training, too busy to have time to participate, and defects in curriculum arrangement were the main factors affecting the CME participation of pediatricians. Conclusion:Pediatricians with different professional title had different training needs for CME contents. Lack of CME resources, contradiction between work and study, and curriculum arrangement deficiencies might be the main influencing factors affecting the CME participation of pediatricians working at county-level medical institutions.

·AIM:To investigate the effect of β1-integrin overexpression on the adhesion and migration of rabbit corneal epithelial (RCE) cells.·METHODS:Eukaryotic expression vector encoding β1-integrin-GFP fusion DNA was transfected into RCE cells,and the β1-integrin-GFP fusion gene was examined by RT-PCR and Western blot.The adhesion to Matrigel and the migration of the transfected cells were determined by adhesion and mobility assays.The phosphorylation of focal adhesion kinase (FAK) was examined by Western blot.·RESULTS:The overexpression of β1-integrin-GFP fusion gene by RCE cells was successfully established.β1-integrin transfection significantly promoted the adhesion of RCE cells to Matrigel ( P < 0.05 ).β1-integrin overexpression also promoted the migration ability of RCE cells and induced FAK phosphorylation in them (P < 0.05).·CONCLUSION:These data suggest that overexpression of β1-integrin promotes the adhesion and migration of RCE cells and that the FAK pathway may play an important role in this process.

Designing of natural product-like compounds using natural products as template structures is an important strategy for the discovery of new drugs. Gambogic acid (GA), which is a Garcinia natural product with a unique caged xanthone scaffold, inhibits potent antitumor activity both in vitro and in vivo. This review summarized the researches on the identification of the antitumor pharmacophore of GA, and the design, structural optimization and structure-activity relationship (SAR) of natural product-like caged xanthones based on it.

OBJECTIVETo investigate the effect of a phosphorothioate antisense oligodeoxynucleotide "ASOND" combined with cis-Diamminedichloroplatinum (DDP), 5-fluorouracil (5-FU) and adriamycin (ADM) respectively on inhibiting the proliferation of HepG2 cells.
METHODSA phosphorothioate antisense oligodeoxynucleotide (5'-ACTCACTCAGG CCTCAGACT-3') targeted to human telomerase reverse transcriptase (hTERT) mRNA, which named cantide, was synthesized. ASODN was transfected into HepG2 by lipofectin. And cell growth activity was evaluated by MTT assay. SAS software and Jin Zhengjun Method were used to evaluate the interaction of ASODN and these chemotherapeutic drugs.
RESULTSCombination treatments with 0.1micromol/L ASODN reduced the IC50 of DDP, 5-FU and ADM from 1.07, 4.15 and 0.29microg/ml to 0.25, 1.52 and 0.12microg/ml respectively. The inhibitory ability of combination treatments on HepG2 cells was higher than that of these drugs alone (F=66.92, 25.96, 8.56, P<0.001). And synergism (Q>or=1.15) was observed at the lower concentration of DDP ( CONCLUSIONASODN may enhance therapeutic effectiveness of chemotherapeutic drugs in human hepatocellular carcinoma cells.

OBJECTIVETo explore the clinical effects of PLIF surgery for elderly patients with lumbar degenerative disease.
METHODSFrom March 2010 to May 2013, 28 patients with lumbar degenerative disease, aged more than 80 years were treated with PLIF surgery. There were 10 males and 18 females, aged from 80 to 93 years old with an average of (85.44±3.66) years. Course of disease was from 3 to 20 years. The operation time, intra-operative blood loss, operation complications were recorded and JOA scores and Macnab criteria were used to evaluate the clinical outcomes.
RESULTSAll patients were followed up from 12 to 40 months with an average of 26.5 months. The average operation time was (150.00±26.42) min and the average intra-operative blood loss was (373.33±99.88) ml. The pre-operative JOA score was 12.30±2.43, and the corresponding postoperative JOA score at the final follow-up was 24.81±2.09 which was much higher than the preoperative one (P<0.01). According to the modified Macnab criteria to evaluate at the final follow-up, 16 patients got an excellent result, 10 good, 2 fair. In the weeks postoperatively, injuries of nerve root happened in 3 cases, superficial wound infection with delayed healing in 3 cases, and tear of the dural sac accompanied with cerebrospinal fluid leakage in 1 case. After long term follow-up, adjacent segment degeneration and the corresponding spinal canal stenosis occurred in 1 case at 34 months after operation. All cases got successful fusion without any displacement of internal fixation and pseudoarthrosis formation.
CONCLUSIONWith proper cases, fully preoperative preparation, perfect intra-operative manipulation and active treatment after operation, even advanced ages older than 80 years with lumbar degenerative disease could get satisfactory outcomes after PLIF surgery.

Objective: To investigate the compliance of smoking cessation and the effect of smoking status on long-term clinical prognosis in male patients with acute coronary syndrome (ACS) after drug-eluting stent (DES) therapy. Methods: A total of 656 ACS patients after DES therapy were studied, according to the post-operative smoking status, the patients were divided into 3 groups: Non-smoking group,n=226, Quit smoking group,n=283 and Persistent smoking group, n=147. The patients were followed-up for the average of 27 months, the major adverse cardio-/cerebral-vascular events (MACCE) were recorded in detail, and the effect of smoking status for MACCE occurrence were evaluated by multivariable Cox regression analysis. Results: The pre-operative smoking rate was 65.5% (430/656) of patients and post-operative smoking rate was 22.4% (147/656). Compared with Non-smoking group and Quit smoking group, the patients in Persistent smoking group had the younger age (P<0.001), more patients with abnormal blood lipids (P=0.005) and having lower level of education (P<0.001). The all cause death rates in Non-smoking group, Quit smoking group and Persistent smoking group were at 1.8%, 1.1% and 6.1% respectively,P=0.004; the MACCE occurrence rates were at 7.1%, 5.3% and 15.0% respectively,P=0.002. Multivariable Cox regression analysis showed that post-operative smoking was the independent risk factor for MACCE occurrence, HR =1.404, 95% CI (1.206-1.793),P=0.008. Conclusion: Smoking is the independent risk factor for MACCE occurrence in male ACS patients after DES therapy.
