The Application of Annular Suture in the Treatment of Postpartum Hemorrhage Caused by Dangerous Placenta Previa / 昆明医科大学学报

Objective To study the effect of pre-operative internal iliac artery capsule combined with the lower segment of the uterus with annular suture on the treatment of postpartum hemorrhage caused by dangerous placenta previa and the long-term effect of the operation. Methods from January 1, 2015 to March 31, 2017, the second people's Hospital of Yunnan province for Cesarean danger in placenta of patients using preset internal iliac artery balloon combined with lower uterine segment ring-shaped suture in the treatment of 22 cases of patients as research group, Lower uterine segment multiple is not used in loop suture for treatment, but has a preset internal iliac artery balloon 18 cases of dangerous patients with placenta previa, as retrospective analysis clinical data of the comparison group. Results Mean blood loss in 22 patients 1329.54±290 ml. Does not occur in all patients around organ damage and other complications. 1 examples of hysterectomy. 5.23 days postoperative average hospital stay. After 3 months of follow-up ultrasound, uterus shape well. In 18 patients in the control group average blood loss 1451.11 ±311 ml of blood loss were significantly higher in the study group, there was a statistically significant difference ( <0.05) . 2 examples of hysterectomy in the control group. Uterine reservations there was statistically significant ( <0.05) . Conclusion Combined preset internal iliac artery balloon uterus circular suturing for the dangerous result of placenta previa with placenta accreta intraoperative uterine bleeding for better effect.

Relationship between insulin like hormone 3 and testicular descent and development / 中华男科学杂志

Testicular descent is an essential step in the course of reproductive system development. The mechanisms involved in the regulation of testis descent is not distinct. Gubernaculum has a very close relationship with testis descent. Maldescent of testis can cause abnormalities of genital system such as testicular underwent (cryptorchidism), dysplasia, tumor, infertility and low sexuality. Recently insulin like hormone 3 is a hotspot of concerning affecting gubernacular development and testicular descent. This article briefly reviews the advances in these aspects.

Study on Effect Factor of the Production of Catechol-type Siderophores Secreted by a Strain of Soil Bacteria / 微生物学通报

Catechol-type siderophores secreted by a strain of soil bacteria in three different medium were assayed by two high-resolution TLC.The results showed different medium had a significant effect on the secretion of catechol-type siderophores,and in three different medium strain S1 produced different catechol-type siderophores.The effect of Al~(3+) on Catechol-type siderophores by S1 were also assayed.The results showed Al~(3+)had a significant stimulation on the secretion of catechol-type siderophores.Moreover,Al~(3+)could to some extent counteract the repression of Fe~(2+)on siderophores production.In KMB medium four catechol-type siderophores were identified and all ones except for 2,3-dihydroxybenzoic acid(2,3-DHBA) had high affinity for Al~(3+).
