Objective To study the prognosis in preeclampsia fetal blood flow detection and perinatals analysis. Methods From July 2012 to July 2014,120 cases of pregnant women at 20 weeks of gestation conducted a retrospective studied in our hospital,were divided into the research group and the control group(n=60),the research group was preeclamp-sia fetus; The control group was normal pregnancy fetus. Two groups all used color doppler ultrasound instrument from 24 weeks-27 weeks+6,to 28 weeks-31 weeks+6,32 weeks to be tested before deliveryvenous catheter and umbili-cal vein,umbilical artery and middle cerebral artery blood flow parameters change,and perinatal prognosis were ana-lyzed. Results Both mild and severe pre-eclampsia fetal resistance index (RI), venous catheter before load index(PLL), peak flow velocity(PVIV), pulse index(PIV), intravenous catheter FenLiuLv(Qdv-venous catheter blood flow/Quv-umbil-ical venous blood flow) values were significantly higher than that of control group, the difference was statistical signifi-cant(P<0.01). The normal end of PLL, PVIV, PIV, S/A and Qdv aderse outcome/Quv values were lower than group, the difference was statistical significant (P<0.05). The team's weight and neonatal Apgar score were lower than the control group,the difference was not statistical significant(P>0.05);Two groups of umbilical vein between pH and umbilical arte-rial blood oxygen saturation had no obvious difference (P>0.05). Conclusion Preeclampsia fetal abnormal venous catheter and umbilical vein blood flow or waveform changes have a certain relationship with poor perinatal outcomes.

Objective:Clinical characteristics and diagnosis and treatment process was reported and analyzed of a patient with brucellosis complicated with thyroid abscess, providing reference for the clinical diagnosis of brucellosis complicated with thyroid abscess.Methods:Clinical medical records of a patient with brucellosis complicated with thyroid abscess who was treated at the General Surgery Department of Yanchi County People's Hospital in Wuzhong City, Ningxia Hui Autonomous Region in November 2021 were collected. The clinical manifestations, blood routine, brucella antibodies, thyroid function, bacterial culture, thyroid ultrasound and other examination results, as well as the diagnosis and treatment process, were comprehensively analyzed. Results:The patient was a male, 61 years old, who presented with a neck mass without typical clinical manifestations of brucellosis. Thyroid ultrasound revealed a space occupying lesion, and the preliminary diagnosis was thyroid cystadenoma. Thyroid right lobe and isthmus resection surgery was performed. During the operation, it was found that some of the thyroid glands were tightly adhered to the cervical blood vessels, so the resection surgery was changed to abscess drainage, and the drainage fluid was purulent and bloody. The bacterial culture result of thyroid purulent fluid (intraoperative puncture fluid and postoperative drainage fluid) was brucella lamblia, and the serum brucella test tube agglutination test titer was 1 ∶ 400 (+++). The patient improved and was discharged after local drainage and anti brucella treatment. Follow up for 4 months showed no abnormalities. Conclusions:Brucellosis which begins with a local infection of the thyroid gland is extremely rare, with no characteristic clinical manifestations, and is prone to misdiagnosis. Timely correction of the surgical plan during the treatment process avoids the removal of the patient's thyroid, which has a certain clinical reference value.
