Objective To examine the effect of labouring in water on analgesia of vaginal delivery.Methods From June 2009 to February 2011,38 women who had volunteered to deliver in water in the obstetrical department were set as the observation group,another 70 women who chose vaginal delivery were named as the control group in the corresponding period.The items of labor pain,satisfaction with the birth experience,length of labor and neonatal outcomes were compared.Results The pain level of the observation group after labouring in water decreased compared with that before immersion in water.The delivery course was not influenced with a high rate of vaginal delivery.Conclusions Labouring in water can alleviate delivery pain,increase rate of vaginal delivery with no influence on delivery course and outcome of mothers and infants.It is a safe and effective analgesia method which should be widely applied.

AIM: To investigate the functions of GR in the course of hepatic secondary injury after severe multiple injury. METHODS: Rat model was produced by adopting severe thoracic impact injury accompanied with mono-side femur fracture, and glucocorticoid receptor was blocked before severe multiple injury. Hepatic macropathology and alterations under light microscope were examined. Maximal binding volume of glucocorticoid receptor (GR) in hepatic tissue was assayed by radio-ligand binding assay and protein content was assayed by Western blot. RESULTS: Maximal binding volume and protein content of GR were gradually decreased in hepatic tissue after severe multiple injury, obviously lower than that in normal control at 4 h after trauma ( P

Objective To analyze the factors related to the occurrence of complications in performing CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle. Methods CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle was carried out in a total of 58 patients. The postoperative complications were recorded, and the related factors causing complication were analyzed. Results Successful puncturing was achieved in all patients with a technical success rate of 100%. Postoperative complications included pulmonary hemorrhage (n=11,19.0%), a little amount of bleeding in needle tract (n=7,12.1%), hemoptysis (n=3,5.2%), hemothorax (n=1,1.7%), and pneumothorax (n=10,17.2%). Chi-square test showed that the occurrence of pulmonary hemorrhage bore a close relationship to the lesion’s diameter, the distance between the lesion and the chest wall, the lesion’s location and times of puncturing (P<0.05). The occurrence of pneumothorax was closely correlated with the age, the distance between the lesion and the chest wall, the presence of perifocal emphysema, the lesion’s location and times of puncturing (P<0.05). Univariate analysis indicated that the postoperative complications were liable to occur in the patients whose imaging examination showed perifocal emphysema and lung hilar lesion, and who had more than two independent risk factors (P<0.05). Conclusion CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle is an accurate and safe technique with relatively higher positive diagnosis rate, but this technique should be carefully used in patients who has perifocal emphysema, or lung hilar lesion, or more than two independent risk factors.(J Intervent Radiol, 2015, 24:792-796)
