Objective To investigate the effect of different maturation methods on mitochondrial functions of oocytes and the possible mechanism. To explore novel ideas for developing assisted reproductive technology (ART). Methods Female mice were used as models and randomly allocated into three groups, COH, IVM and NC control. Oocytes maturated with different methods which were all simulated with those treatments in human IVF cycle. Immunofluorescence were used to measure the mitochondrial membrane potentials and analyze the cy-toskeleton. Results The mitochondrial membrane potential in the COH group was significantly lower than that in NC group and IVM group (P < 0.05). The proportion of normal cytoskeleton including spindle structure and chromosome configuration in the COH group and IVM group were significantly lower than that in the NC group (PCOH < 0.01, PIVM < 0.05). Conclusions Both COH and IVM can affect mitochondrial functions.

Objective:
To investigate the effect of pituitrin-water separation on hemoglobin and ovarian function in laparoscopic ovarian chocolate cyst removal.
Methods:
From February 2018 to February 2019, 82 patients with ovarian chocolate cyst removed by laparoscopy were selected from the Second Affiliated Hospital of Wenzhou Medical University.They were randomly divided into observation group and control group according to the digital table, with 41 cases in each group.The control group underwent traditional laparoscopic tear-and-tear ovarian cyst removal, while the observation group underwent pituitrin-water separation.The changes of perioperative indicators, the decrease of hemoglobin (Hb) before and after operation, the positive rate of normal ovarian tissue on cyst wall and the number of normal follicles attached to cyst wall, the changes of serum hormone levels before and after operation were compared between the two groups.
Results:
The amount of bleeding during operation in the observation group [(58.97±8.74)mL] was less than that in the control group [(118.93±24.21)mL], and the operation time in the observation group[(57.46±8.27)min] was shorter than that in the control group [(87.38±10.19)min] , the differences were ststistically significant between the two group(
