Objective To compare analgesic efficacy of intravenous postoperative and preemptive analgesia with flurbiprofen axetil combined with small dose of morphine and with morphine alone. Methods One hundred and twenty patients were randomly divided into four groups: group A,morphine 30 mg +0.9% NaCl for postoperative analgesia,n=30;group B,morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30;group C,flurbiprofen axetil 100 mg + morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30;group D,flurbiprofen axetil 100 mg before operation + morphine 20 mg +0.9% NaCl for postoperative analgesia,n=30.The drugs in each group were diluted to 100 mL and infused by a pump at a rate of 2 mL/h with a patient-controlled analgesia(PCA)bolus of 2 mL after a loading dose of 5 mL.The visual analogue scale(VAS),demanding times for PCA and incidence of side effects were recorded during the period of postoperative 24 h. Results The VAS of group B at 3 h after operation was significantly higher than those of the other three groups(P

A comparison of plant and animal stem cells can highlight core aspects of stem-cell biology. In both kingdoms, stem cells are defined by their clonogenic properties and are maintained by intercellular signals. The signaling molecules are different in plants and animals stem cell niches, but the roles of argonaute and polycomb group proteins suggest that there are some molecular similarities.

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.

Objective:To investigate the effect of standardized nutritional therapy for gastric cancer during perioperation.Methods:Seventy-six patients with gastric cancer who underwent nutritional therapy were randomly divided into observation group (38 patients) and control group (38 patients),between May 2015 and May 2016.In the observation group,the nutritional therapy was made by medical workers who had received the training of Total Nutritional Therapy (TNT) and Goal Nutrition Therapy (GNT) for Cancer Patient.In the control group,the nutritional therapy was given by doctors according to their conventional experience.Nutritional conditions,gastrointestinal function recovery conditions,complications and hospital stays were compared between the two groups.Results:First,the weight,triceps skinfold thickness and arm muscle circumference of preoperative 1 day and postoperative 7 day in the observation patients were significantly higher than those in the control patients (P ＜ 0.05).Second,the level of serum prealbumin of preoperative 1 day,postoperative 1 and 7 day in the observation patients was significantly higher than that in the control patients (P ＜ 0.05).Third,the time of anus exhaust and defecate in observation group was significantly shorter than that in the control group (P ＜ 0.01).Fourth,each group had one patient who suffered bleeding after operation,and 2 patients in control group had anastomotic leakage.Fifth,the time of hospital stays in the observation group was significantly shorter than that in the control group (P ＜ 0.01).Conclusion:The standardized nutritional therapy for gastric cancer can improve the patient's nutrition status,promote the recovery of gastrointestinal function,and then decrease the time of hospital stays during perioperation.

Objective To learn the psychological needs of the hospital staff in terms of their life,medical care and psychological health.Methods 2910 hospital staff were interviewed with questionnaires and the outcomes analyzed with x2 test and descriptive analysis.Results 96.9％of the surveyed found themselves in need of psychological counseling; considerable consulting needs of the staff; most of them turn to friends to complain instead of their leaders.Conclusion The psychological counseling should be enhanced to build effective communication channels and ease stress of the staff.

AIM: To determine multifocal visual evoked potential (mVEP) in the prediction of postoperative visual acuity in cataract. METHODS: We examined 30 normal eyes as control and 60 eyes of 52 cataract patients, senile cataract in 27 cases 30 eyes, cataract with glaucoma in 25 cases 30 eyes by mVEP examination. All patients underwent phacoemulsifi-cation (Phaco) and intraocular lens (IOL) implantation. After surgery,best corrected visual acuity (BCVA) was examined at 1 week, 1 month, and 3 months respectively.RESULTS: The mean amplitude and latency in mVEP responses between normal control group were 183±11nV, 95±8ms, and in senile cataract group were 177±10nV, 96± 8ms respectively, there were no significant difference between two groups (P>0.05). The mean amplitude and latency of cataract with glaucoma 138±7nV, 99±6ms were significantly different comparing to both control and senile cataract group (P<0.05). After surgery, the am-plitude and latency were 276±11nV and 93±8ms respec-tively, which did not change significantly comparing to the normal eyes (P<0.05), their visual function got no obvious damage and visual recovery were better (BCVA≥0.8). While those with central amplitude 221±6nV and latency 105±7ms that were significantly deviated from control group (P<0.05), and their visual function were seriously damaged and visual recovery were much poorer (BCVA<0.3).CONCLUSION: mVEP waveform might enable us to evaluate objective visual function detection before cataract surgery. A subject with visual function damage, their mVEP responses to stimulation were severely changed when it compared to controls.

·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.
