Objective To investigate the effects of uterine resection and uterine arterial embolization on the function of ovary. Methods The serum concentrations of estrin(E 2), progestogen(P), follicule stimulating hormone(FSH), luteotropic hormone(LH) and prolactin(PRL) were measured in 15 patients with uterine resection and 22 patients with uterine arterial embolization; including 23 patients with uterine leiomyoma and 29 normal women. We compared the results of the five hormones in each group. Results The serum concentrations of E 2 and P in the group of uterine resection were lower than the normal control group, there was a significant difference between them. Compared the serum concentrations of E 2 and P in the group of uterine arterial embolization and normal control group, there was no significant difference. The serum concentration of PRL in the group of uterine leiomyoma was higher than the normal control group with significant difference. When the uterus was resected or uterine artery was embolished, the serum concentration of PRL decreased remarkably. Conclusions Uterine resection has effects on the function of ovary, but uterine arterial embolization would not. PRL may be one of the factors causing the formation of uterine leiomyoma.

Objective To study the change of the oxygen-carried function of stored red blood cells,which was warmed in room temperature and calorstat.Methods Randomly removed from 4 ℃storage refrigerator,red blood cell suspension were put in room temperature 30 min (group N)and 37℃ calorstat 30 min (group H),and samples taken to examine electrolyte,blood gas,free Hb,ATP content,2,3-DPG content,oxygen affinity(P50).Results In two groups,blood pH value and blood Na+ did not change obviously due to heating.The content of blood K+ and free Hb increased,glucose fell,but there was no statistically significant difference.The content of ATP and 2,3-DPG in eryth-rocyte increased and P50 increased after heating (P <0.05),which increased more significantly in group H compared with group N (P<0.05).Conclusion Heating stored blood up to 37 ℃ can in-crease the oxygen-carried function of red blood cells,which contribute to improve the effectiveness of transfusion.

Objective To investigate the possible role of protein kinase(PK) activity in the induction of AP-1 by ox-LDL in mesangial cells and to elucidate the upstream signal pathways involved in the ox-LDL-induced AP-1 binding. Methods Rat mesangial cells were randomly divided into the normal cells, ox-LDL-treated cells and PK inhibitor + ox-LDL-treated cells. Treatments with the PKC inhibitor bisindolylmaleimide I, the PKA inhibitor H89, the PTK inhibitor genistein (GEN), the MEKi inhibitor PD98059, or the p38 MAPK inhibitor SB203580 were applied prior to a 24-hour incubation of ox-LDL in mesangial cells. The phosphorylation of MAPK families was detected by Weatern blot analysis. AP-1 binding was determined by gel shift assay. Results Ox-LDL stimulated the phosphorylation of JNKi/SAPK and p38 MAPK( P 0. 05) . Bisindolylmaleimide I at 50, 100, 200 nmol/L appreciably reduced the ox-LDL-induced AP-1 binding. H89 at 0. 5, 5 umol/L significantly inhibited AP-1 binding by ox-LDL. GEN at 25, 50 umol/L did not reduce the AP-1 binding by ox-LDL, but when GEN rose up to 100 umol/L, the ox-LDL-induced AP-1 binding significantly decreased in mesangial cells. However, SB203580 and PD98059 did not reduce the ox-LDL-induced AP-1 binding in the present study. Conclusion Multiple protein kinases may involve in the stimulation of AP-1 by ox-LDL in mesangial cells.

Objective To investigate the expression pattern of skeletal muscle specific miR-206,myogenesis related myoD which change with time in dcnervated muscle atrophy rats.Methods From June,2015 to January,2016,40 SPF sprague-dawley rats were equally classified into 5 groups randomly according to standard settled before,5 groups were separately defined as denervated 0d group,denervated 1d group,denervated 7d group,denervated 14d group,and denervated 28d group.Each group contained 8 rats.The rats atrophy models were established by cutting sciatic never on left side.According to the different denervated time,the gastrocnemii on both sides were obtained under anesthesia,respectively.The wet weight ratio of two compared gastrocnemii were measured,and the gastrocnemii transection was observed by HE stain,measured the expression of myoD protein by western blot,obtained the expression of miR-206,myoD mRNA by qPCR.Results According to our study on rats denervated atrophy models,the wet ratio of compared gastrocnemius would decrease rapidly,by HE stain,decease of cross sectional area in muscle fiber was observed as well as degeneration.Collagen fibers hyperplasia appeared and increased with time change.Wet ratio and transaction aera ratio of group Od,1d,7d,14d,28d were 0.99±0.04,0.92±0.07,0.68±0.11,0.39±0.06,0.27±0.07 and 0.99±0.02,0.96±0.04,0.51±0.09,0.34±0.08,0.23±0.03 respectively,difference between experimental groups and control group were statistically significant (P< 0.05),the differences between each experimental groups were also statistically significant (P< 0.05).After qPCR test of miR-206,myoD mRNA expression,it was found that their expression patterns were similar,miR-206,myoD mRNA increased at first and would reach the expression peak at the 7 th day,after that their contents decreased but still higher at the 14th day when compared with that at the 1 st day.Their expression of group 0d,1 d,7d,14d,28d were 0.24±0.06,0.34±0.04,0.68±0.04,0.49± 0.07,0.25±0.03 and 0.41 ±0.06,0.49±0.09,0.93±0.06,0.66±0.03,0.39±0.04,respectively.All experimental groups were statistically significant different when compared with 0d group except 1d group (P< 0.05),the differences between each experimental groups were also statistically significant(P< 0.05).The protein expression of myoD was also measured by western blot test,which showed nearly the same expression pattern as the mRNA expression pattern.After injury,the protein expression increased and reached the expression peak at the 7th day.The relative expression of myoD of group 0d,1d,7d,14d,28d measured by grey ratio were 1.03±0.05,1.06±0.06,1.42±0.10,0.66±0.13,0.24±0.07,respectively.The difference between experimental groups and control group were statistically significant (P < 0.05),the differences between each experimental groups were statistically significant (P < 0.05) as well.Conclusion The degree of muscle denervation atrophy was related to the denervated duration in rats.The expression regulation of miR-206 and myoD in gastrocnemius was similar during the muscle denervation atrophy,which suggesting having internal relationship between miR-206 and myoD.
