Developing college students' credit quality is the demand of the time and society,and the teachers' credit quality is the key to achieve this goal.However,the present situation is not optimal.To train the students with good credit,we should develop the teachers' credit quality,combine the education-leading and system-control,and construct an effective system containing education-leading,supervising,and rewards or punishments appraisal.

ObjectiveTo compare clinical and laboratory outcomes of in vitro maturation (IVM) with in vitro fertilization-embryo transfer (IVF-ET) in treatment of infertility associated with polycystic ovary syndrome (PCOS).MethodsFrom Jan.2007 to Dec.2010,infertile patients with PCOS underwent 701 cycles in First Affiliated Hospital of Wenzhou Medical College were studied retrospectively.Those were divided into 293 cycles of IVM group and 408 cycles of IVF/intra-cytoplasmic sperm injection ( ICSI ) group.The average transplantation rate,mean number of retrieval oocytes,maturation rate,fertilization rate,cleavage rate,high quality embryo rate,embryo implantation rate,pregnancy rate per transfer,pregnancy outcomes and incidence of ovarian hyperstimulation syndrome (OHSS) of the two methods of treatment were compared between two groups.ResultsThere were 275 cycles in IVM group and 342 cycles in IVF/ICSI group established embryo transfer.The transplantation rate was 93.9％(275/293)in IVM group and 83.8％ (342/408) in IVF/ICSI,which reached statistical difference (P ＜ 0.01 ).The maturation rate of 56.64％,cleavage rate of 88.08％,high quality embryo rate of 38.72％ and embryo implantation rate of 17.8％ in IVM group were significantly lower than 91.09％,94.91％,51.50％ and 25.4％ in IVF/ICSI group (all P ＜ 0.01 ).The clinical pregnancy rate per transfer were 37.8％ (104/275) in IVM group and 44.2％ (151/342) in IVF/ICSI group,which did not show statistical difference (P＞0.05).The mean number of oocytes ( 12.9 ±6.5 vs.12.9 ±7.9) and fertilization rate (76.52％ vs.70.75％ ) didn't show significant difference between IVM group and IVF/ICSI group ( P ＞ 0.05 ).The 21.3％ ( 87/408 ) cycles presented mild to moderate OHSS and 2.0％cycles(8/408)presented severe OHSS in IVF/ICSI group.While,no OHSS cycles were observed in IVM group.Conclusion IVM could get similar clinical pregnancy rates compared with IVF/ICSI in patient with PCOS,however,it can avoid occurrence of OHSS.

Objective To compare the effects of bilateral and non- bilateral frontal pneumocephalus on acute agitation after craniotomy for brain tumor. Methods The clinical data of 406 brain tumor patients who had underwent craniotomy in Maoming Traditional Chinese Medicine Hospital and Guangdong Provincial People′s Hospital from January 2014 to January 2019 were retrospectively analyzed. The patients were divided into bilateral frontal pneumocephalus group (92 cases) and unilateral frontal pneumocephalus group (314 cases) according to frontal pneumocephalus within 12 hours after operation. Within 24 hours after operation, the sedation-agitation scale (SAS) was evaluated, and SAS≥ 5 scores was defined as acute agitation. Results The incidence of postoperative acute agitation, rate of postoperative sedatives use and postoperative hospital stay in bilateral frontal pneumocephalus group were significantly higher than those in unilateral frontal pneumocephalus group: 23.9% (22/92) vs. 8.6% (27/314), 14.1% (13/92) vs. 3.5% (11/314) and (12.2 ± 2.6) d vs. (8.5 ± 1.6) d, and there were statistical differences (P＜0.01 or ＜0.05). Conclusions Brain tumor patients who had bilateral frontal pneumocephalus after craniotomy are more likely to develop acute agitation.
