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 find out the influencing behavioral factors of antibiotics usage in population in Lanzhou. Methods Status of antibiotics usage was investigated in four hospitals in Lanzhou. Results The self-medicine pro portion among patients with respiratory system infection, infectious di arrhea, urinary system infection and choleic system infection were 44.22%, 31. 76%, 22.07% and 6.61% respectively. Patients having higher income used some antibiotics at a middle price, while patients having lower income used antibiot ics at a lower price. The educate d person applied some antibiotics at a lower price, but the illiterate person us ed some antibiotics at a higher price. The combined usage of antibio tics was affected by the disease program and distance of seeing doctor. The fart her distance away from hospital, the more proportion of antibiotics(two or thre e) used combinedly. Conclusions The antibiotics usage was affe cted by the disease variety, disease program, distance to hospital, average inco me and educ ated level.

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.

Objective To explore the causes of congenital hypothyroidism by single photon emission computed tomography(SPECT) thyroid imaging.Methods Nineteen cases with congenital hypothyroidism were collected,and SPECT thyroid imaging was performed 15 minutes late after injected 99m TcO_ 4- 18.5-37.0 MBq.Results Five cases were found with normal glands,1 case with enlarged thyroid, 2 cases with enlarged thyroid and increased radiation,4 cases with ectopic thyroid,4 with a hypogenetic thyroid,and the last 3 cases showed no thyroid imaging.Conclusions The causes of congenital hypothyroidism can be found by SPECT thyroid imaging,which is important to the diagnosis of congenital hypothyroidism combined with detection of T_3,T_4,TSH.
