Clinical effects of oxytocin induced labor route / 中国生化药物杂志

Objective To study and analyze the clinical effects of different oxytocin induced labor routes. Methods From March 2015 to September 2016, 100 pregnant women who needed induced labor or induced oxytocin were selected in our hospital. They were randomly divided into the control group and the study group, with 50 patients in each group. The control group with traditional infusion method, given intravenous indwelling needle puncture method in patients with the study group, select the vein elastic and straight, thick, pay attention to the reasonable sealing, adjust the dropping speed according to the patients with uterine contraction. The infusion speed, safety and accuracy of the patients in the study group and the control group were compared and analyzed. Results After the corresponding administration route, there were 0 patients with drop velocity errors in the study group, and 12 patients in the control group. In the control group, the rate of drop error was 24％, which was significantly higher than that of the study group (0％), with statistical difference (P<0.05). Among the patients in the study group, the number of blocked tubes was 1, the probability was 2％, the rate of subcutaneous infiltration was 4％, and the incidence of needle prolapse was 0％. In the control group, the rate of subcutaneous exudate was 10％, the probability of blockage was 8％, and the incidence of needle prolapse was 6％. The average time spent by the study group on regulation of drip speed was (8.09 ±2.10) s, significantly shorter than that of the control group (78.90 ± 9.20) s, with statistical difference (P<0.05). Conclusion Intravenous catheter infusion of oxytocin administered with traditional delivery mode, simple operation, can significantly reduce the drop speed error probability, the clinical effect is ideal, has the meaning of promotion.

The individualized programs for frozen-thawed embryo transplantation / 实用医学杂志

Objective To analyze the influential factors of clinical pregnancy rate of the frozen-thawed embryo transplantation. Methods The data of 3 192 FET patients in the reproductive medicine center of our hospital up to May 2014 were analyzed retrospectively. According to ages, reasons of infertility, types of infertility, duration of infertility, drug regimen, the number and the time of embryo transplantation, we divided these patients into six groups for comparing the clinical pregnancy rate. Results The FET clinical pregnancy rate of the under 35 years group was higher than the 35~39 years group and the over 39 years group (33.96%vs. 27.58%and 19.35%; P<0.05, respectively). The duration of infertility in the clinical pregnancy group was significantly shorter than the non-pregnancy group (P<0.05). The clinical pregnancy rate in the group with three embryos transplanted was higher than the group with only two embryos transplanted (41.01% vs. 28.75%; P < 0.05). Among the group with the age of over 40 years, those with three embryos transplanted had a higher clinical pregnancy rate than those with only one embryo transplanted (25.49% vs. 0.00%; P < 0.05). The clinical pregnancy rate of the frozen blastocyst transplantation group was higher than that of the cleavage-stage transplantation group (40.00%vs. 26.27%;P<0.05). Conclusion Age, infertility duration, the number and the time of frozen embryo transplantation may affect the clinical pregnancy rate among the FET patients. An individualized transplantation program based on age may improve the patient′s clinical pregnancy rate.

The Comparative Analysis on CT and X-ray Film in Diagnosis of Transparent Foreign Body in Trachea and Bronchus / 实用放射学杂志

Objective To study the CT signs of bronchotracheal transparent foreign body and its diagnostic value.Methods The X-ray and CT findings of bronchotracheal trasparent foreign body in 46 cases were analysed comparativly.Results Among 46 cases,9 cases of trachea foreign body,13 cases of right bronchial foreign body,7 cases of left bronchial foreign body,2 cases of both sides of bronchial foreign body were showed directly by CT,and 8 cases of right bronchia foreign body,6 cases of left bronchia foreign body,1 case of both sides of bronchia foreign body showed indirectly on CT,the sensitivity was 100 percent,while the foreign body and its anatomical location could not be showed on X-ray film,but the indirect signs just like pulmonary emphysema,obstructive pulmonitis and drowned lung etc,could be showed by X-ray films in 34 cases.In another 12 cases were negative,the sensitivity was 73.9 percent.Conclusion The transparent foreign body can not be showed but indrect signs by X-ray film;While CT scan can not only shows the anatomical location of foreign body,but also the shape and size of the foreign body,it offers more information than X-ray films and has important refering value to clinicians to take out the foreign body.

Esophageal Carcinoma:CT Staging and Evalualion of Resectability / 实用放射学杂志

Objective To evaluate CT staging and resectability of esophageal carcinoma.Methods The esophageal barium examination,esophagoscopy and CT scan were performed in 42 cases with esophageal carcinoma.CT findings were put the stress on analyzed.Results CT clearly demonstrated the location, thickness, actual length and extent of esophageal carcinoma as well as its relation with surrounding structures in all 42 cases.According to staging standard of Moss and Reining there were four stages,Ⅰ stage 0 case,Ⅱ stage 33 cases,Ⅲ stage 6 cases,Ⅳ stage 3 cases.In all cases,operations were in 34 cases,detecting were in 3 cases,no-operations were in 5 cases.Conclusion CT imaging playes an important role in preoperative diagnosis,staging and the evaluation of resectability of esophageal carcinoma.

The Application of the Super-short Time Exposure of the DR Adjustable Control in Radiography of the Infant Chest / 实用放射学杂志

Objective To explore the applied value of the super-short exposure time of the DR adjustable control in radiography of infant chest.Methods 100 chest radiographic films of infant in adjustable control group and fixed control group respectively were selected randomly.The quality of all films was evaluated by 4 technicians in charge in 4 grades(A,B,C and waste)and the detective rate of the tiny parts of the images was also evaluated.Results DR adjustable control:the rate of grade A,B,C and waste was 70%,20%,10% and 0% respectively.DR fixed control:the rate of grade A,B,C and waste was 42%,41%,15% and 2% respectively.The detective rate of tiny parts was 100% and 90% in DR adjustable control group and DR fixed control group respectively.Conclusion DR adjustable control chest film in infant is better than DR fixed control in image quality.DR adjustable control system is good for radiographic diagnosis.
