Objective To investigate the effect of Gardiner bacteria infection on preterm delivery and changes of endocrine hor-mone levels.Methods Application of Gardiner bacteria fluorescent marker detection kit in 120 cases of suspected Gardiner bacteria infection pregnant women with immunofluorescence assay,and the levels of serum follicle stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2),progesterone (P)were measured at the same time,90 cases of non maternal Gardiner bacteria infec-tion were enrolled as control.Results After the treatment,98 cases of pregnant women with Gardiner bacteria infection should ex-perienced premature delivery (24-37 week),accounted for 81.67%,compared with the normal pregnant women were statistically significant (P <0.05);and 22 cases of Gardiner bacteria infection pregnant women after treatment no premature birth,accounted for 18.33%,and to all pregnant women infected Gardiner bacteria and experiencing preterm delivery and the control group levels of endocrine hormone were determined,compared the results of FSH,LH,found no significant differences(P >0.05),E2 increased,P decreased,changed significantly (P <0.05 ).Conclusion The probability of premature delivery in women infected with Gardiner bacteria is significantly higher than that of normal pregnant women,at the same time the secretion of hormone changes,so dealing with pre pregnancy and early pregnancy should carry owt Gardiner bacteria examination.

Objective:To make a magnetic separator and verify its application effect in the removal of foreign bodies in laparoscopic surgery.Methods:From February 2015 to September 2019 in Chengdu Sanliu Third Hospital Affiliated to Southwest Medical University, 46 surgical patients to be searched for during the laparoscopic surgery, such as needle breakage, needle drop, and titanium clip shedding, were selected as the research object. The observation group used a self-made laparoscope with a magnetic separator, and the control group used traditional methods, such as: laparoscopy to flip the tissue and C-arm X-ray positioning. The time to find the foreign body left after surgery, the incidence of postoperative subcutaneous emphysema, and the satisfaction of the surgeon were compared between the two groups.Results:The time to find the foreign body left after surgery was (15.36±3.62)min in the observation group and (75.83±10.30)min in the control group, there was significant difference( t value was 29.384, P<0.01). The incidence of postoperative subcutaneous emphysema was 13.70% (3/22)in the observation group and 83.30%(20/24)in the control group, there was significant difference( &chi;2 value was 37.079, P<0.01). The satisfaction of the surgeon was 100.0%(22/22)in the observation group and 16.7%(4/24)in the control group, there was significant difference( &chi;2 value was 48.765, P<0.01). Conclusions:For patients with foreign bodies left after laparoscopic surgery, the use of magnetic separators can significantly shorten the time to find foreign bodies, reduce the incidence of postoperative subcutaneous emphysema, and increase the satisfaction of the surgeon.
