Objective To investigate the effects of preemptive analgesia with parecoxib sodium on postoperative analgesia and delirium after nerve injury-free surgery for fracture of thoracic and lumbar vertebrae and to promote the postoperative rehabilitation of the patients. Method 80 patients meeting the criteria were selected. and randomly divided into observation group and control group.40 patients each group. The observation group used parecoxib sodium for preemptive analgesia. while the control group used sufentanil. and the analgesia effects and the incidences of delirium were observed. Results The differences in operative time and intra-operative blood loss between the patients of the two groups were statistically insignificant. In 2 h. 6 h. 12 h.24 h and 48 h after the surgery.the VAS score and the accumulative time of intravenous self-controlled analgesia pump being pressed of the observation group were significantly lower than those of the control group. and the differences were statistically significant (P<0.05). The first time for the patients of the observation group to press the intravenous self-controlled analgesia pump is (3.84±0.62) h after the surgery, is significantly later than that of the control group (1.05±0.47)h.and the difference is statistically significant (P<0.05). The incidence of delirium in 7 days after the surgery in the patients of the observation group was 10.00%. and is significantly lower than that of the control group (25.00%) (P<0.05). Conclusion Using parecoxib sodium for preemptive analgesia before nerve injury-free surgery for fracture of thoracic and lumbar vertebrae can elevate the postoperative analgesia effects of the patients.decrease the incidence of postoperative delirium, and is highly safe and consequently worthy of clinical application.

Objective To examine cardiotoxicity of anthracyclines and trastuzumab in patients with breast cancer by two dimensional speckle tracking imaging. Methods Fifty-eight human epidermal growth factor receptors-2 (HER2) positive patients with breast cancer treated by anthracyclines and trastuzumab were monitored by echocardiography before treatment (Group A), after completion of anthracyclines (Group B), and at follow-up of 3 months (Group C) and 12months (Group D) after using trastuzumab. LVEDD, IVSTD, PWTD, LVEDV, LVESV were measured in the apical four- and two-chamber views. Left ventricular ejection fraction (LVEF) was measured using a modified Simpson's biplane method. Global longitudinal strain (GLS) and longitudinal strain rate (LSR) were calculated via Qlab8.0 analysis software off-line. Results LVEDDs in A-D groups were (47.95 ±4.12), (48.45 ±4.02), (48.91 ±3.83) and (49.98 ±3.72) mm, respectively, and LVEDVs were (108.70 ±21.26), (111.90 ±20.91), (113.50 ±20.25) and (119.20 ±20.02) ml, respectively. LVEDD, PWTD [(9.14 ±0.76) mm vs. (9.00 ±0.82)mm], LVEDV, LVESV [(54.60 ±14.58) ml vs. (50.97 ±14.35) ml] were increased in group B compared with those in A group (all P<0.05). LVEDD and LVEDV were increased in group C(P<0.05) compared with those in group B. CLVEDD, LVEDV, LVESV [(59.18±13.88) ml vs. (55.23± 13.81) ml] were increased in group D compared with group (P<0.05). Differences of LVEF between group C and group D were statistically significant[(59.48±2.62) % vs. (62.00±1.40) %, P<0.001]. Differences of GLS [(-21.16±2.33)%, (-19.76±1.98) %, (-19.22±1.89) % and (-18.74±1.79) %, respectively, P<0.001] and LSR [(-1.27±0.11), (-1.22±0.09), (-1.17±0.07) and (-1.14±0.06) /s, respectively, P<0.001] among four groups had all statistically significant. Conclusions Longitudinal left ventricle systolic function are impaired in patients with breast cancer treated by anthracyclines and trastuzumab. GLS and LSR of myocardium traced by two dimensional speckle tracking imaging would be useful for early evaluation of the severity.

OBJECTIVE To explore the role of P38MAPK inhibitor on the soft palate reconstruction of the rats with chronic intermittent hypoxia. METHODS The animals were divided into normal control group, hypoxia control group and SB203580+hypoxia group (every group 20 rats). After 5 weeks, the expressions of p38MAPK and p-p38MAPK protein on the soft palate of the rats were detected with immunohistochemical techniques and western blot. RESULTS Compared with the normal control group, the soft palate tissue thickness of the hypoxia group were increased most obviously; Levels of p38MAPK were increased in hypoxia control group; Compared with the hypoxia control group, the levels of p-p38MAPK group were decreased in SB203580+hypoxia group. CONCLUSION p38MAPK may play important roles in the soft palate reconstruction of the rats with chronic intermittent hypoxia.
