Methods 67 cases of the patients with gastric malignant tumor received total gastrectomy and alimentary canal restruction of SS loop /Roux_Y, P loop/Roux_Y or Roux_Y. The diety complaint, digestive tract symptom and the nutritional status of the patients were investigated 6 months after operation. Results Compared with Roux_Y or Lahey+Broun mode,the complication frequency of SS loop /Roux_Y and P loop/Roux_Y modes was significantly lower(P

Objective To explore the early diagnosis and operative treatment of duodenal injury. Methods The clinic data of 36 patients with duodenal trauma were retrospectively analyzed. Results Among 36 cases of duodenal injury, 4 cases (4/36,10.3%) were located in the first section of duodenum, 26 cases (26/36,72.2%) were between the second and third sections of duodenum, 6 cases (6/36,16.7%) were located in the fourth section of duodenum, and 14 cases were accompanied by other organ injury. The frequency of the postoperative complications was 13.9%, the curative rate was 94.4%, and the mortality was 2.8%. Conclusion Familiarizing with charateristics of duodenum injury, early diagnosing, mastering surgical exploration indication, selecting suitable operative approach, effective duodenal decompression, sufficient drainage and anti-infection treatment can improve the curative rate of duodenal injury.

Objective To evaluate the effects of epidural anesthesia by target controlled introduction (TCI) of 0.375% ropivacaine (Ropi) combined with propofol on the blood pressure (BP) and heart rate (HR) of the patients in different age during thoracotomy. Methods Seventy five ASA Ⅱ-Ⅲ patients undergoing elective resection of esophageal carcinoma were divided into 3 groups according to their age (25 each): groupⅠ (aged 40～59), group Ⅱ (aged 60～74) and group Ⅲ (aged ≥75). An epidural catheter was inserted at the T6～T8 interspace in all patients before induction, and then 5ml of 1% lidocaine was given to all the patients. For each patient, 6 ml of 0.375% Ropi was given epidurally. Anesthesia was induced with propofol TCI 3?g/ml, fentanyl 3?g/kg and atracurium 0.6mg/kg. Tracheal incubation was performed when bispectrum index (BIS) value was less than 50. The patients were mechanically ventilated. Anesthesia was maintained with propofol TCI and epidural anesthesia of 0.375% Ropi at 6ml/h. Propofol was subsequently adjusted to maintain BIS at 50～55 during operation. The concentrations of propofol TCI, mean arterial pressure (MAP), HR, and the amount of ephedrine were continuously monitored during anesthesia. Results MAP in group Ⅱ and Ⅲ was lower than that in groupⅠ (P0.05). The amount of ephedrine used in group Ⅱ and Ⅲ was higher than that in group Ⅰ (P

Objective:To analyze the ultrasonographic images and clinical characteristics of congenital mesoblastic nephroma (CMN), and to investigate the differential performances with Wilm′s tumor (WT).Methods:Twenty-one cases of CMN patients confirmed by pathology from December 2008 to December 2019 in Beijing Children′s Hospital, Capital Medical University were collected as the CMN group, and in the same criterion, 51 cases of WT patients were taken as WT group. Ultrasonographic images and clinical characteristics were collected retrospectively, and then the tumor size, site, echo and age were compared and analyzed between the two groups. ROC curve was used to evaluate the differential performance.Results:The difference analysis showed that except for echo ( P=0.694), there were statistically significant differences in tumor size, site and age between the two groups (all P<0.05). In prenatal, the incidence of CMN was significantly higher than WT (61.9% vs 3.9%, P<0.001), and the specificity was 96.1%. The median age (interquartile range) of CMN after birth was significantly earlier than WT( Z=-4.044, P<0.001). The area under the ROC was 0.949, the best cutoff was 112.5 days, with a sensitivity of 87.5% and a specificity of 93.9%. Conclusions:It is difficult to distinguish CMN and WT by echo, but the diagnosis performance can be improved through combining tumor size with site, especially age.

BACKGROUND:Undergoing femoral head replacement in senile osteoporosis patients with intertrochanteric fracture is a chal enging problem.
OBJECTIVE:To explore the clinical effect of the use of joint instal ation and fracture reduction on the treatment of unstable intertrochanteric fractures in elderly patients.
METHODS:A total of 21 elderly patients with unstable intertrochanteric fractures underwent femoral head replacement. Simultaneously, we col ected clinical data of 20 elderly patients with unstable intertrochanteric fractures undergoing internal fixation of dynamic hip screw. Operation time, blood loss amount, time of walking practice after replacement, complications, and Harris score were compared between the two groups. Clinical effects in patients with femoral head replacement were observed.
RESULTS AND CONCLUSION:Al patients were fol owed up for averagely 20 months (ranged from 6 months to 36 months). After replacement, the incision was first healing. The operation time of femoral head replacement was short;blood loss amount was less;the time of walking practice was early. However, no significant difference in Harris score was detected between the two groups (P>0.05). After femoral head replacement, no infection, inversion and shift, or hip joint loose occurred. Results suggested that correct anteversion angle, eccentricity and femoral calcar size should be identified before the implementation of artificial joint replacement for the elderly femoral intertrochanteric fracture. After implantation of the prosthesis, reduction and fixation of trochanter and femoral calcar bony landmarks are simple easily operated surgery. It can reduce blood loss amount, shorten operation time and elevate clinical effects.

Objective To detect the expression of survivin in suprarenal epithelioma(SRE) and elucidate its function in suprarenal epithelioma.Methods A total of 53 SRE specimens and 8 nomal nephridial tissues were obtained.Immunohistochemistry method was used to test protein expression of survivin.Semi-quantitative RT-PCR was used to measure survivin mRNA levels.Results Survivin protein were detected in 33 of 53(62.3%) SRE tissues.In contrast,no expression of survivin in nomal nephridial tissues was detected.The expression rate of survivin mRNA in tumor tissues(56.25%,18/32) was significantly higher than that in normal tissues(0,0/8).Conclusion Over expression of survivin is common in suprarenal epithelioma.Survivin may play an important role in SRE and is associated with prognosis.

Fifty-six patients with abdominal wall endometriosis(AWE)were assigned into the proliferous group or the secretory group and the expression of estrogen receptor(ER)in the entopie,ectopic and normal endometrium was investigated.In the proliferous group,the positive ER expression rate on the entopie endometrium(85%)was significantly higher than that on the normal(60%)or ectopie endometrium (58%)(P<0.05).In the secretory group,the positive ER expression rate on the eetopie endometrium (57%)was significantly higher than that on the entopic (26%) or normal endometrium(25%)(P< 0.05).There was significant difference in the entopie and normal endometriilm between the two groups (P<0.01):however,there was no significant diffeFence in the ectopic endometrium.Abnormal ER expression on the entopic or ectopic endometrium may play a role in the pathogenesis of AWE.

BACKGROUND: Kyphoplasty-assisted bone cement augmentation can be used in lumbar pedicle screw fixation of osteoporotic patients.OBJECTIVE: To assess the fixation strengths of loosened sacral screws augmented with kyphoplasty-assisted and traditional bone cement techniques.METHODS: Fresh sacra were harvested from nine osteoporotic cadavers. After testing bilaterally placed unicortical and bicortical pedicle screws, two unicortical pedicle screws with the traditional and kyphoplasty-assisted cement augmentations were established on the same sacrum. Following 2000 cyclic compression loading to screw head on a MTS machine, their maximum pull-out forces were recorded and compared. RESULTS AND CONCLUSION: The bone mineral densities of nine specimens were ranged from 0.61 to 0.77 g/cm2 (0.71 g/cm2 in average). The mean maximum pull-out forces of unicortical and bicortical screws, and traditional and kyphoplasty-assisted cement screws were 203, 325, 437, and 565 N, respectively. The pull-out force was significantly higher in bicortical screw compared with unicortical (P < 0.05); however, these two fixations exhibited markedly lower pull-out strength compared with two cement augmentation techniques (P < 0.05). The pull-out strength was significantly higher in kyphoplasty-assisted cement augmentation group compared with traditional bone cement technique (P < 0.05). In addition, a significant positive correlation was exhibited between bone mineral density and pull-out force for the four fixations (P < 0.05). Results demonstrated that traditional and kyphoplasty-assisted cement augmentations can serve as the salvage technique for loosening sacral screw. However, kyphoplasty-assisted augmentation can provide higher stability.
