Objective To explore the role of the change of the CD11b expression in hyperleukocytosis and acute promyelocytic leukemia(APL) differentiation syndrome, we observed the effects of all-trans retinoie acid(ATRA) and trioxide arsenic(ATO) alone or the combination together with daunorubicin (DNR) on CD11b expression of human APL cell line NB4 cells. Methods By using the mono-antibody of CD11b FITC-conjugated, we monitored the level of CD11b expression of NB4 cells by flow cytometry. Results With the length of the 1 μmol/L ATRA exposure,the CD11b expression was increased. Exposed to ATRA for 24 h, 48 h, 72 h and 168 h;the CD11b expression of NB4 cell was (33.34±3.15)%, (55.59±5.13)%, (86.08±5.12)% and (90.69±2.69)%, respectively which were higher than control group and the difference was statistically significant (P<0.01). With the length of the 1 μmol/L ATO exposure, the CD11b expression showed no significant difference with control group(P>0.05), but was significantly lower than that in ATRA exposure(P<0.01). Exposed to 1 μmol/L ATRA combined with 1 μmol/L ATO for 72 h and 168 h, the CD11b expression were (18.81±1.40)% and (25.61±4.54)%, which were significantly higher than that in control group (P<0.05, P<0.01), but significantly lower than ATRA exposure (P<0.01). With the exposure to 1 μmol/L ATRA combined with 1 μmol/L ATO and 1 μmol/L DNR, the CD11b expression was also significantly lower than ATRA exposure (P<0.01) and showed no difference with control group (P>0.05). Conclusion By avoiding the increase of CD11b expression of promyelocytic leukemia cells, ATRA combined with ATO or two drugs together with DNR could play a role in eliminating incidence of hyperleukocytosis and retinoic acid syndrome.

Objective:To evaluate the value of adjuvant radiotherapy for stage Ⅱ endometrial cancer after surgery.Methods:40 patients with stage Ⅱ endometrial cancer with over five years follow up were analyzed vetrosectively.27 cases received subradical hysterectomy,and additional pelvic lymph node dissection in 13 cases.6 cases were treated with surgery alone.34 cases were treated with postoperative pelvic irradiation and additional vaginal brachytherapy in 12 cases.Results:The 5 year survival rate,pelvic failure rate and extrapelvic recurrence rate were 65%(26/40),17.5%(7/40),25%(10/40) repectively.The 5 year disease free survival rate,pelvic failure rate and extrapelvic recurrence rate were 70.5%(24/34),5.9%(2/34),29%(10/34) respectively in 34 patients with postoperative radiotherapy.5 cases with surgery alone recurrenced at the vaginal residual within two years.The late complications were 44%(15/34),including proctitis,cystitis and intestinal obstruction.Conclusion:Postoperative radiotherapy for stage Ⅱ endometrial cancer can improve the tumor local control and increase the late complications.

In top-quality course construction of medical ethics,it is necessary to attach importance to practical operation as well as the consistency of theoretical logic.To well adapt to the current medical practice and medical technical advances,the idea of medical ethics should include virtue,harmony and value.Virtue is the prominent concept in top-quality course construction of medical ethics.Harmony is the core idea of medical ethics,and value is the innovative idea to solve the questions caused by life technologies.Therefore,in the top-quality course construction of medical ethics,coordination and unification of the above three ideas must be maintained in order to defend the demonstration significance of top-quality course of medical ethics.

Objective: To develop parental punishment style the questionnaire. Methods: Based upon previous literature about parental punishment style and expert interview, data were collected for the parental punishment style questionnaire. A sample of 1028 junior high school students were asked to complete the questionnaire and 158 of them was given retest after a month. Results: Taken from the questionnaire by exploratory factor analysis four factors were compatible. The results of confirmatory factor analysis showed a good fit to the data. The internal consistency reliability of father and mother questionnaire was satisfactory, with Cronbach ? coefficient 0.91; and the test-retest reliability was also satisfactory, with test-retest correlation coefficient 0.88 and 0.89, which showed good content validity and high construct validity. Conclusion: The questionnaire has good reliability and validity, and meets the need of psychometrics.

The nafion/carbon nanoparticles (CNPs) composite film modified glassy carbon electrode was pre pared by dropwise method, and the electrocatalyst of H_2O_2 at Nafion/CNPs modified electrode was investiga ted.The results show that electrocataytic activitie for detection of H_2O_2 at the modified electrode is very good.The biosensing application of CNPs was demonstrated through fabrication of an electrochemical biosensor.The biosensor was constructed by encapsulating glucose oxidase in the Nafion/CNPs composite film.The biosensor had good electrocatalytic activity toward oxidation of glucose.The glucose biosensor shows a linear range from 2.0 × 10 ~(-6) to 6.0×10~(-3) mol/L with a detection limit of 1.6×10 ~(-6) mol/L.The biosensor shows high stabili ty, good reproducibility and can avoid the commonly coexisted interference.In addition, real rat serum samples were analyzed by this biosensor with satisfactory results.

Objective To understand the iodine nutrition of children in Qiandongnan and to provide the scientific evidence for prevention and control of iodine deficiency disorders (IDD). Methods The 3200 urinary samples of pupils aged 8-10 were collected from 80 primary schools in 16 county and city in Qiandongnan in 2006. The urinary iodine content was tested by colorimetric ceric-arsenic assay and vitriolic ammonium assimilation. Results The median of urinary iodine content in children samples was 362.9?g/L, the percentage of urinary iodine( ≥100?g/L) was 98.00%, in which ≥300?g/L was 65.31%, the percentage of urinary iodine(

Objective To study the value of adrenal venous sampling (AVS) in the differential diagnosis of primary aldosteronism (PA).Methods Fourteen patients (11 adenoma and 3 adrenal hyperplasia) clinically diagnosed as PA were examined with AVS for measurement of plasma aldosterone and cortisol levels.Selectivity of AVS was assessed by the aldosterone level in each adrenal vein and in the infrarenal inferior vena cava plasma.The data were compared with CT and postoperative pathologic result.Results The diagnosis of adenoma by AVS in 9 (9/11) cases was in accordance with the postoperative pathologic findings.The diagnosis of hyperplasia by AVS in all 3 cases was in accordance with CT scanning result.Conclusion AVS should be selected to distinguish the PA without overt occupational lesion in CT scanning.

Objective To determine and compare the minimum local analgesic concentration(MLAC) of ropivacaine and bupivacaine in continuous block of axillary brachial plexus for postoperative active mobilization of flexor tendon. Methods Seventy ASA Ⅰ or Ⅱ patients undergoing relaxation of flexor tendon were randomly allocated into 2 groups (n = 35 each): ropivacaine group (group R) and bupivacaine group (group B). A catheter was inserted into axillary sheath using B. Braun stimulating intraducer, 24-48 h after operation. 30 min before functional exercise 20 ml of ropivacaine or bupivacaine was injected through catheter. The minimum local analgesic concentration of both local anesthetics was determined by up-and-down sequential test. The first concentration of both local anesthetics was 0.1%. The next concentration of local anesthetic was determined by response of the previous patient. The analgesia efficacy was assessed using 100 mm VAS score (0 = no pain, 100 mm = worst possible pain) . Increase/decrease in VAS by 10 mm was defined as effective. An effective result resulted in increase/decrease by 0.01% in the next patient. The motor block was also recorded.Results The two groups were comparable with regard to age, sex, body weight and baseline VAS score. The MLAC of ropivacaine was 0.133% [95% confidence interval (CI), 0.128%-0.138%] and MLAC of bupivacaine was0.121% (95%CI, 0.116%-0.126%). The analgesic potency of ropivacaine was 10% less than that of bupivacaine. The potency ratio of ropivacaine to bupivacaine was 0.91. The degree of motor block is higher with bupivacaine than with ropivacaine. Conclusion The results of our study show that the analgesic potency of ropivacaine is 10% less than that of bupivacaine. The degree of motor block is higher with bupivacaine than with ropivacaine.
