Fine needle aspiration cytopathology of the breast is an effective means of distinguishing malignant from benign,and the aspirated sample collections techniques is the primary and key part of fine needle aspiration.Fine needle aspiration cell block has been improved and used on preoperative breast cancer molecular portraits.This paper will provide an introduction to application of specimens collection techniques,application and development of fine needle aspiration cell block on preoperative breast cancer molecular portraits.

Objective:To evaluate the effects of intermittent change the angle of operating table on the skin in pressure areas of patients in prone position.Methods:A total of 150 hospitalized patients for elective surgical treatment in Yantai Yuhuangding Hospital from January 2019 to June 2019 were selected as subjects. The patients were divided into control group, 15° test group and 30° test group by random number table method, with 50 patients in each group. The control group received routine intraoperative pressure ulcer prevention measures, the 15° test group on the control group, the itinerant nurses adjusted the angle of the operating table according to the left 15°-supine-right 15° every half hour, and the 30° test group on the control group, the itinerant nurses adjusted the angle of the operating table according to the left 30°-supine-right 30° every half hour. The incidence of surgically related pressure ulcers and doctors' satisfaction with the surgical position of the three groups of patients were evaluated.Results:Pressure ulcers occurred in 8 patients of the control group, the incidence of pressure ulcers was 16%. Pressure ulcer occurred in 0 patient of the 15° test group, the incidence of pressure ulcers was 0. Pressure ulcers occurred in 2 cases in the 30° test group, the incidence of pressure ulcers was 4%. The difference was statistically significant ( χ2 value was 10.120, P<0.05). Further comparison showed that the incidence of pressure ulcers was statistically significant between the control group and the 15° test group ( P<0.016 7), while the incidence of pressure ulcers was not statistically significant between the control group and the 30° test group, between the 15° test group and the 30° test group ( P>0.016 7). The results of the postoperative doctors' satisfaction with the surgical body position were (27.880 ± 1.637), (27.520 ± 1.693), (26.920 ± 1.947) points in the control group, the 15° test group and the 30° test group, there was a statistically significant difference among the three groups ( F value was 3.779, P<0.05). Further comparison showed that there was no statistically significant difference in the score of surgical position satisfaction between the control group and the 15° test group, between the 15° test group and the 30° test group ( P>0.05). The satisfaction score of surgeons in the control group was higher than that in the 30° test group, and the difference was statistically significant( P<0.05). Conclusions:Intermittent adjustment of surgical position can reduce the incidence of pressure ulcers and improve the quality of nursing in the operating room without affecting the convenience of the surgeon. The optimal effect was achieved by adjusting the angle of the operating bed according to the left-leaning 15°-supine-right-leaning 15°at an interval of 30 minutes.

Objective The purpose of this paper was to evaluate the clinical value of double-contrast barium(DCB) combined with CT in the diagnosis of gastric carcinoma.Methods 112 patients with gastric carcinoma confirmed by surgery and pathology between 1990 and 1997 were included.69 patients took DCB of the upper gastric intestinal tract.43 patients were given CT scans,in whom 32 patients took DCB before CT.Results The accuracy of gastric carcinoma staging determined by DCB were 91.3%.The accordant rate of gross type of gastric carcinoma determined by DCB and the combined way were respectively 67.74% and 72.41%,superior to CT(47.22%,?

Objective To investigate the features,prevention and treatment of complications of ultrasound-guided hepatic puncture biopsy.Methods One hundred and seventy-five cases underwent ultrasound-guided hepatic puncture biopsy were retrospectively analyzed.Results The incidence of complications was 16 cases (9.1%),including 5 cases with vasovagal episodes(2.9%),4 cases with ache which needed medicine treatment (2.2%),3 cases with hemorrhage in liver capsule(1.7%),3 cases with hypoglycemia(1.7%),1 case with serve hemorrhage in abdominal cavity(0.6%).Hemorrhage limited in liver capsule,vasovagal episodes,hypoglycemia and ache were relieved with corresponding treatments.One case with hemorrhage in abdominal cavity was handled with percutaneous microwave ablation therapy guided by contrast-enhanced ultrasound.Conclusions Ultrasound-guided hepatic puncture biopsy has good value and low complication.The most severe complication is hemorrhage,which can be handled with percutaneous microwave ablation therapy guided by contrast-enhanced ultrasound.

ObjectiveTo investigate the clinical efficacy of bidirectional Glenn shunt with noncardiopulmonary bypass(CPB) for treating congenital heart disease.MethodsThe clinical data of forty-four patients receiving bidirectional Glenn shunt from August 2005 to August 2011 were analyzedretrospectively,twenty-three cases of which were treated by bidirectional Glenn shunt with non-CPB (non-CPB group) and twenty-one with CPB (CPB group).The duration of ventilator-assisted breathing,chest drainage volume,amount of blood product usage,postoperative hospital stay and pulse oxygen saturation (SpO2) before leaving the hospital were compared and analyzed between two groups.ResultsForty-four patients were all cured.The duration of ventilator-assisted breathing,chest drainage volume and the amount of blood product usage of non-CPB group were less than those of CPB group [ (4.5 ± 1.3 ) h vs.(6.7 ± 1.5 ) h,(4.6 ± 1.4 ) ml/kg vs.(7.7 ± 3.1 ) ml/kg,( 221.8 ± 97.6 ) ml vs.( 423.4 ± 149.7 ) ml,P ＜ 0.05 ].There was no significant difference of the postoperative hospital stay and SpO2 before leaving the hospital between non-CPB group and CPB group[ (7.4 ± 2.3 ) d vs.(7.8 ± 1.9) d,0.91 ± 0.05 vs.0.88 ± 0.39,P ＞ 0.05 ].Conclusion Bidirectional Glenn shunt with non-CPB is a safe and feasible surgical approach,which is worthy of promotion.

Objective To review the experience in managing severe major jugular vascular injuries. Methods Fifteen cases (11 men and 4 women, aged 18～49 years) treated by operation were collected. The injuried vessels included common carotid artery, internal carotid artery, subclavian artery and accompanying veins, carotid reconstruction was performed by jugular vein transplantation and followed by wrapping with PTFE artificial blood vessel in 15 cases. Result All the fifteen patients were cured and the vasculars were well-functioning 3～12 weeks after the surgery. Conclusion The mortality of severe large cervical vascular injuries is very high because of acute bleeding, cerebral ischimia and suffocation. In managing this catastrophe, keeping the airway clear and stop bleeding effectively are fundamental. Good knowledge and expertise in vascular and microvascular surgery are mandatory for the success of the procedure.

Breast calcification is a specific sign of nonpalpable early breast cancer,the accurate localization and biopsy can obviously improve the diagnosis rate of early breast cancer,and imaging-guided needle localization is the premise of accurate biopsy of breast calcification.As the recommended guidance,mammography-guided localization and biopsy has certain limitations in localizing and biopsying breast calcification,however,high-resolution uhrasound makes it possible to localize the nonpalpable calcification in breast,and which has a certain advantage.
