ABSTRACT
Based on the outpatient interview and literature review,the initial framework of the outpatient experience of human caring scale was formed with 9 dimensions of outpatient process.The research aim was to improve the scale by Delphi method.Sixteen experts in medical management,human caring or medical education were invited to evaluate the importance of the dimensions and items of the scale and provided some expertise via filling out the Delphi consultation questionnaires twice in the consulting round.In the first round,the recovery rate showing the experts' positivity was 80％;the coefficient of reliability (Cr) ascertaining the authority of the evaluation was 0.92;the mean and full mark ratios responding the concentration of the evaluation were 2.88-4.94 and 6.25％-93.75％ respectively;the coefficients of variation (CV) and the Kendall's W determining the concordance of the evaluation were 5.06％-52.15％ and 0.21-0.24 respectively.In the second round,the recovery rate was 93.75％;the Cr was 0.93;the mean was 3.93-4.93;the full mark ratios were 26.67％-93.33％;the Kendall's W was 0.14-0.31,the CV was 5.25％-23.61％.Via the two-round Delphi study,the scale that included 10 dimensions and 61 items has been improved.Ten dimensions are pre-hospital medical service,guidance,registration,waiting,diagnosis & treatment,paying,inspection & assay,medicine receiving,therapy/injection/transfusion and global evaluation.It was concluded that Chinese scholars have paid high attention to human caring and outpatient experience.The experts have given high agreements about the dimensions which were established with Chinese outpatient process.The dimensions are different from the similar researches about outpatient experience study.In the future,it is necessary to survey the outpatients to test the construct validity,internal consistency reliability and others of the scale to improve the scale.

ABSTRACT
Objective The embryonic development is usually observed for 5-6 days during the process of embryo culture in most embryonic laboratories.The article aimed to explore the application of D 6+D7 frozen-thawed blastocyst transfer in patients with di -minished ovarian reserve(DOR). Methods Retrospective analysis was conducted on 285 patients with DOR who were treated with in-vitro fertilization and embryo transfer (IVF-ET) in our center from 2015 to 2017.Frozen embryos were harvested from the natural cycle , mini-stimulation protocol, ovulation induction during the luteal phase , followed by frozen-thawed embryo transfer with a total of 442 cycles. The frozen embryos were divided into cleavage embryo group and blas -tocyst group according to different life stages , and comparison was made in general data and pregnancy outcome between the two groups .The blastocyst transfer group was subdivided into Day 5 group and Day6+Day7 group followed by the comparison of different pregnancy outcome between the two groups . Results Patients with DOR were treated with frozen-thawed blastocyst transfer with 291 cycles in cleavage embryo group and 151 cycles in blastocyst group.The implantation rate, clinical pregnancy rate, and ongoing pregnancy rate of blastocyst group were significantly higher than those of cleavage embryo group ( 44.62％ vs 22.46％, 50.33％ vs 33.33％, 37.75％ vs 21.65％, P<0.05) and the abortion rate of blastocyst group was significantly lower than that of cleavage embryo group (35.05％ vs 25％, P<0.05).As to the frozen blastocyst transplantation cycle , the number of D5 blastocysts was 69, and D6+D7 blastocyst was 76. The embryo planting rate, clinical pregnancy rate, continued pregnancy rate and abortion rate of D 6+D7 group were higher than those of D5 group(39.74％ vs 50％, 44.93％ vs 55.26％, 34.78％ vs 39.47％, 22.58％ vs 28.57％), but the difference was of no statistical significance(P>0.05). Conclusion In patients with DOR, the transplanted blastocyst can significantly improve the pregnancy out -come, increase the clinical pregnancy rate and reduce the abortion rate .The embryo planting rate and clinical pregnancy rate of the transplanted D6+D7 blastocyst were higher than those of D 5 blastocyst, but the difference was not statistically significant .The abortion rate was also increased.Therefore, when the number of embryos is limited, patients with DOR may consider transplanting D 6+D7 high-quality blastocysts in order to get a certain clinical pregnancy rate .
ABSTRACT
In the present study, the complete genomes of four common (4/EV71/Wenzhou/CHN/2014, 15/ EV71/Wenzhou/CHN/2014, 116/EV71/Wenzhou/ CHN/2014, and 120/EV71/Wenzhou/CHN/2014) and two virulent (11/EV71/Wenzhou/CHN/2014 and 109/EV71/Wenzhou/CHN/2014) enterovirus 71 (EV71) isolates were sequenced and described. They are 7405 bp in length and belong to EV71 sub-genotype C4 (C4a cluster). Nucleotide sequence alignment revealed six nucleotide variations (GP151→TP151, GP199→AP199, GP261→TP261, AP328→CP328, GP422→AP422, and GP437→TP437) in the two virulent isolates within the 5'UTR of the IRES element. RNA secondary structure predictions of IRES and FCE indicated that the common isolates shared similar structures, which were different from those of the virulent isolates. Moreover, the GP114→CP114 and GP151→TP151 mutations in the virulent isolates contributed to the formation of the unique RNA secondary structures in SL II. Furthermore, nucleotide/amino acid sequence alignments of 82 EV71 isolates indicated that six sites (TP488 and CP577 in the 5'UTR; AsnP57 in 2A; IleP56 in 3C; CP10 and AP47 in the 3'UTR) are potentially associated with the neurovirulence of EV71. Finally, the 3D structures of 2A were analogous, whereas the structures of VP1 and 3C were variable.

<p><b>OBJECTIVE</b>To investigate the protective effect of epigallocatechin gallate (EGCG) on mouse sperm in vivo.</p><p><b>METHODS</b>A total of 64 six-week-old male Kuming mice were randomly divided into eight groups of equal number to be treated with normal saline (negative control), Cyclophosphamide (CP) at 30 mg/kg (positive control), and CP followed by EGCG (experimental) at 20, 40, and 80 mg/kg, respectively, given every other day for 10 days. At 4 and 5 weeks after treatment, the bilateral testes of the mice were harvested for examination of sperm abnormality.</p><p><b>RESULTS</b>EGCG did not increase the rate of CP-induced sperm abnormality in the mice, but reduced it instead with the prolonged time of treatment.</p><p><b>CONCLUSION</b>EGCG protects mouse sperm in vivo.</p>
