Objective To compare the consumption of the drugs for patient-controlled intravenous analgesia (PCIA) in patients with different blood groups. Methods One hundred female ASA Ⅰ or Ⅱ patients, aged 30-50 yr, body mass index ＜ 30 kg/m2 , scheduled for elective total hysterectomy or myomectomy, were enrolled in this study. The patients were divided into 4 groups according to the blood group: group A ( n= 25), group B ( n = 30), group AB ( n = 11 ) and group O ( n = 34). Patients received iv injection of flurbiprofen 30 min before the end of surgery and sufentanil at the end of surgery. PCIA with sufentanil 1.2 μg/ml ( bolus dose 2.0 ml, background infusion 0.5 ml/h, lockout interval 5 min) was performed when the VAS score ≤4. The loading dose and consumption on 1 st and 2nd day after operation for sufentanil were recorded. The adverse reactions were observed.Results The loading dose and consumption on 1st day after operation for sufentanil were the highest in group A and B, the second in group AB, and the lowest in group O among the 4 groups. Conclusion The consumption of the drugs for PCIA is different in patients with different blood groups.

ObjectiveTo investigate the effects of exploratory behaviors on depression-like rats treated with sleep deprivation,and the mechanism of the point of brain-derived neurotrophic factor (BDNF).Methods30 Sprague-Dawley (SD) rats were randomly divided into normal group,depression group and deprivation group,and the depression model of rats were established by chronic unpredictable stress.At the day of 6th,12th,18th,24th the deprivation group was deprived sleep for 24h by the method of multi-platform water environment,and then all groups were on the open-field test.The approach of immunohistochemistry and retrovirus polymerization chain reaction measured BDNF expression level in the hippocampal neurons.ResultsThe four open-field test scores of the day of 6th,12th,18th,24th indicated that the scores of deprivation group was a low-to high trend,and at the open-field test of the 24th day was significantly different compared with depression group(P ＜0.01 ),while no significant difference was found compared with the normal group (P ＞ 0.05 ).Compared with depression group( gray level:108.53 ± 4.45,positive area rate:0.0747 ± 0.0262 ),BDNF protein expression was significantly higher in the hippocampal neurons of deprivation group( gray level:116.00 ±5.61,positive area rate:0.2034 ± 0.0352 ) (P ＜ 0.05 ),while there was no significant difference in normal group ( gray level:117.27 ±10.66,positive area rate:0.2252 ±0.1143 ) (P＞0.05 ).Results of RT-PCR were in accord with that of immunohistochemistry.ConclusionSleep deprivation can improve the exploratory behaviors of depressive rats and the mechanism may be related to the increasing concentration of BDNF in hippocampal neurons.

Objective To investigate the MRI characteristics of low-grade endometrial stromal sarcoma (LGESS),and to improve the accuracy of the diagnosis.Methods The clinical and MRI data of 4 cases with LGESS confirmed by surgery and pathology were analyzed retrospectively.All cases underwent conventional MRI scans.Results All 4 cases had enlarged uterus in different degrees. The average diameter of lesions was 9 cm (range from 5 cm to 12.1 cm).Uterine cavity masses were found in 3 cases,all of which were solid masses and invaded into myometrium exhibiting disconnection or disappearance of the connection band of uterus,and one of which involved the bladder and right ureter,oviduct and ovary.The solid tumors in 3 cases showed isointensity on T1 WI and slight hyperin-tensity on T2 WI,1 of which was heterogenous with dilated vascular void signal in the inner and peripheral portion.In addition, myometrial mass was found in 1 case,which was cystic with septum and clear boundaries.The cystic tumor showed hypointensity on T1 WI and hyperintensity on T2 WI with hypointensive internal septum.There were 3 cases accompanied with uterine leiomyoma, and 1 case with pelvic lymph node metastasis.Conclusion Most of endometrial stromal sarcomas are located in uterine cavity,a few in myometrium.The tumors are solid,few can also show cystic,showing invasive growth into myometrium.The manifestation of low-grade endometrial stromal sarcoma has a certain characteristics on MRI,which is low or iso-signal intensity on T1 WI and high signal intensity on T2 WI,the signal intensity may be heterogeneous,so MRI can provide help for the correct diagnosis of the disease.

Objective To observe the effects of dorsiflexion ankle foot orthotics (d-AFO) on pelvic control of hemiplegic patients by analyzing the time-space gait parameters and 3D pelvic motion parameters.Methods Fifteen hemiplegic patients (14 male and 1 female) were enrolled in this study.The time-space gait parameters and pelvic 3D motion parameters were collecte with a Motion Analysis System while the patients were asked to walk under 3 conditions:wearing d-AFO (5°dorsiflexion),f-AFO (0°dorsiflexion) or barefoot.Results It was found that,while wearing d-AFO,the velocity,the paralyzed step length and the nonparalyzed step length were significantly increased,and the step width was significantly decreased when compared with those while walking barefoot (P ＜ 0.05).Comparison between wearing d-AFO and f-AFO showed that the sagittal and coronal plane inclinations,but not the transverse rotation of pelvis were significantly decreased when wearing the d-AFO (P ＜ 0.05).Conclusions d-AFO can significantly improve pelvis control and increase gait stability in hemiplegic patients.
