目的 探讨腹腔镜下输卵管妊娠开窗取胚术后缝合与否对输卵管再通、宫内妊娠率的近期影响。方法 回顾分析2008年4月－2010年4月112例有保留生育功能意愿且具备随访条件的输卵管妊娠患者行腹腔镜手术的临床资料。根据手术方法将患者分为两组：A组54例，行患侧输卵管开窗取胚术，术后缝合输卵管；B组58例，行患侧输卵管开窗取胚术，术后不予缝合输卵管。两组术毕均予甲氨喋呤20 mg注射于病变输卵管处系膜，并行通液了解患侧输卵管通畅情况（对侧输卵管均通畅）。3个月后比较两组患侧输卵管的再通情况，并随访其近期（12个月内）宫内妊娠率、重复性异位妊娠率情况。 结果 A组54例患者术中患侧输卵管通畅48例，通而不畅6例；术后3个月B型超声监测下通液43例通畅，10例通而不畅，1例不通，通畅率79.63%。B组58例患者术中患侧输卵管通畅54例，4例通而不畅；术后3个月B型超声监测下通液37例通畅，13例通而不畅，8例不通，通畅率63.79%。近期（12个月内）宫内妊娠率、重复性异位妊娠率情况：A组54例，实访42例，宫内妊娠29例，占69.05%；重复性异位妊娠6例，占14.29%。B组58例，实访44例，宫内妊娠18例，占40.91%，重复性异位妊娠12例，占27.27%。A组术后患侧输卵管通畅率、宫内妊娠率高于B组，而重复性异位妊娠率明显降低，两组差异有统计学意义（P＜0.05）。 结论 腹腔镜下输卵管妊娠开窗取胚术后行输卵管缝合，可以减少对患侧输卵管损伤并恢复其正常的解剖结构，从而有效地保留患者生育功能。术后患侧输卵管通畅率、宫内妊娠率明显高于术后不缝合者，而重复性异位妊娠率明显降低。
【摘要】 目的 探讨骨形成蛋白-2（bone morphogenetic protein-2，BMP-2）对室管膜前下区（anterior subventricular zone，SVZa）神经干细胞DLX5表达的影响。 方法 体外培养SVZa神经干细胞，用BMP-2及其拮抗剂Noggin诱导SVZa神经干细胞，分别用免疫荧光染色和逆转录-聚合酶链反应（RT-PCR）检测DLX5表达变化。 结果 BMP-2组SVZa神经干细胞DLX5蛋白表达和DLX5mRNA表达水平明显高于对照组（Plt;0.05），且该效应能被其拮抗剂Noggin特异性地抑制。 结论 BMP-2是DLX5上游调节基因，可促进SVZa神经干细胞DLX5的表达。【Abstract】 Objective To investigate the effect of bone morphogenetic protein-2 (BMP-2)on expression of DLX5 of neural stem cells in anterior subventricular zone (SVZa). Methods The neural stem cells of SVZa were separated and cultured in vitro, which were induced by BMP-2 and Noggin.Immunofluorescence staining and RT-PCR were employed to assay the expression of DLX5. Results The percentages of expression of DLX5 protein and DLX5 mRNA in BMP-2 group were much higher than those in the control group (Plt;0.05). And this induction could be specifically blocked by Noggin. Conclusion BMP-2 is an upstream gene of DLX5; BMP-2 can promote the expression of DLX5 of the neural stem cells of SVZa.

ObjectiveTo investigate the effect of behavior intervention through diets and exercises on blood glucose controlling in patients with gestational diabetes mellitus (GDM), and to provide the basis for GDM therapy. MethodsA total of 116 patients with GDM diagnosed and treated in the Sixth Affiliated Hospital of Sun Yat-sen University between March 2011 and December 2012 were taken as our study objects, including 72 patients in the study group and 44 patients in the control group, based on their will. For patients in the study group, we carried out behavior interventions through diets and exercises, including dietary guidance, giving pamphlet and formulating exercise plan, while for patients in the control group, we only gave them oral guidance and publicity materials. The same questionnaire was used to collect all the patients' information. Follow-up was done once in every 3 days, and rechecking was performed 2 weeks later. The results of oral glucose tolerance test and the rate of pathoglycemia were compared in these groups before and after intervention. ResultsThe fasting blood glucose, 1- and 2-hour blood glucose were lowered after the behavior intervention in the study group (P<0.05), which were also significantly lower than the control group (P<0.05). Fasting blood glucose, 1- and 2-hour pathoglycemia was significantly lower in the study group than that in the control group and that before intervention (P<0.05). ConclusionCombination of diets and exercises can control levels of blood glucose in GDM patients, and is an important therapy for GDM.
Objective The aim is to sort CD90+ subpopulation cells in human liver cancer cell lines and investigate efficiency of magnetic cell sorting (MACS) on sorting the liver cancer stem cells. Methods ①Expressions of CD90. Immunohistochemical method was used to determine the expressions of CD90 in normal liver tissues in 8 cases, liver cancer and adjacent liver cancer tissues in 58 cases. ②Screened the cell lines. Huh-7, MHCC97-H, Bel-7402, and SMMC-7721 cell lines were divided into blank control group and experimental group (5.5×105 cells per hole, 1 hole), cells of the experimental group were added with 5 μL CD90–PE while cells of the blank control group were treated with 5 μL CD90–PE non fluorescent antibody. Determined the proportion of CD90+ cells in the 2 groups by flow cytometry (FCM). ③MACS. Huh-7 and MHCC97-H cell lines were labeled with magnetic beads respectively and sorted by MACS, 1 mL cell suspensionsorted by magnetic sorting (MS) was collected as CD90– group, and 1 mL PBS after MS wash was collected as CD90+ group, as well as blank control group and experimental group. Determined the proportion of CD90+ cells in 4 groups by FCM. Two times of MACS were performed in Huh-7 cells. ④Serum free culture and serum culture. Huh-7 cells were divided into serum-free culture group and serum culture group (1 hole), and proportions of CD90+ cells were determined by FCM at 1 week after culture. Results ①The positive rate of CD90 was 0 (0/8), 65.5% (38/58), and 20.7% (12/58) in normal liver tissues, liver cancer tissues, and adjacent liver cancer tissues respectively, and the positive rate of CD90 was higher in liver cancer tissues than those of normal liver tissues (χ2=6.78, P<0.05) and adjacent liver cancer tissues (χ2=20.83, P<0.05). ②For Huh-7, MHCC97-H, SMMC-7721, and Bel7402 cell lines, the proportions of CD90+ cells in the experimental group was 0.851%, 1.090%, 2.710%, and 4.050% respectively, the proportions of CD90+ cells in the blank control group was 0.241%, 0.688%, 1.890%, and 2.080% respectively, so we chose Huh-7 and MHCC97-H cell lines to perform MACS. ③Results of MACS for Huh-7 cell line. For the first MACS, the proportions of CD90+ cells in the blank control group, experimental group, CD90– group, and CD90+ group was 0.241%, 0.851%, 0.574%, and 1.100% respectively. For the second MACS, the proportions of CD90+ cells in the blank control group, experimental group, CD90– group, and CD90+ group was 0.032%, 0.961%, 0.426%, and 9.700% respectively. Conclusions The normal liver tissues do not express the CD90, but the liver cancer tissues express CD90 highly. There is a few CD90+ cells in Huh-7 and MHCC97-H liver cancer cell lines. The MACS has a certain effect on improving the proportion of CD90+ cells in the cell lines. The serum-free suspension culture has no effect on enriching CD90+ cells.
Objective To explore the effects of utilization of new partogram on the progress of labor and intervention in the labor. Methods We reviewed nulliparous women who had vaginal delivery at our hospital from January 1st, 2015 to December 31st, 2017. They were divided into control group (group A) (n=200; the old labor standard was used during this time) and observation group (the new labor standard was used at the same time). The observation group was sub-divided into group B (n=100, the duration of dilatation of cervix from 0 to 3 centimeters greater than or equal to 16 hours after parturition), group C1 [n=100; the second-stage duration (t) was greater than or equal to 2 hours, and less than 3 hours), and group C2 (n=100; t was greater than or equal to 3 hours). We compared the differences in intervention at the stages of labor such as using oxytocin to strengthen the contractions, artificial rupture of membranes, using phloroglucinol to soften the cervix, urinary catheterization, and manual rotation of fetal head among the groups. We also compared the differences in fetal presentation position, head tumor, fetal position, cephalopelvic disproportion and progress of the drop when the dilatation of cervix get to 10 centimeters among the groups. Results In the comparison among group A, B, C1 and C2 in rates of using oxytocin to strengthen the contractions, using phloroglucinol to soften the cervix, urinary catheterization and manual rotation of fetal head, the differences were statistically significant between group C2 and the other groups (P<0.008 5). The differences among group C1, C2 and A were statistically significant in duration of the first stage of labor (P<0.05). The same result was found between group B and A in duration of the second stage of labor (P<0.05). In the comparison of the different ratios of fetal presentation position between group A and C1, and group A and C2, when the dilatation of cervix get to 10 centimeters, the differences were significant (P<0.017), except at +1 position. The differences in whether the fetal presentation was producing head tumor and occipital anterior position among group A, C1, and C2 were statistically significant (P<0.017), but there was no difference between group A and C1 (P>0.017) in occipital anterior position. In the comparison of the different progress of the drop when the dilatation of cervix had got to 10 centimeters, 0–1 hours: the differences were statistically significant among group A, C1, and C2 (P<0.05) ; 1–2 hours: the difference was statistically significant between groups C1 and C2 (P<0.05). In group C1, there was a statistically significant difference between 0–1 hour and 1–2 hours (P<0.05). In group C2, there was no statistically significant difference among 0–1 hour, 1–2 hours and 2–3 hours (P>0.05). Conclusions According to the new labor standard, the rates of intervention in the labor would not increase, but when the second-stage duration is greater than or equal to 3 hours, the frequency would increase. We should deal with the abnormal factors affecting labor in time, and try to control the duration in 3 hours.
Objective To explore the correlation between overweight, obesity and incidence of type 2 diabetes mellitus (T2DM). Methods Databases including PubMed, EMbase, The Cochrane Library (Issue 3, 2012), CNKI, VIP, CBM and WanFang Data were searched from inception to May, 2012 to collect the cohort studies on the correlation between overweight, obesity and incidence of T2DM. The studies were screened according to the inclusion and exclusion criteria by two researchers independently, the quality was evaluated, the data were extracted, and then meta-analysis was performed using RevMan 5.1 and Stata 11.0 software. Results A total of 8 studies involving 101 864 participants were included. The results of meta-analysis showed that, compared with the normal weight population, the onset risk of T2DM was obviously higher in the overweight (RR=2.59, 95%CI 2.11 to 3.19, Plt;0.000 01), and obese (RR=6.28, 95%CI 4.99 to 7.91, Plt;0.000 01) populations. In the subgroup analysis, the onset risk of T2DM was higher in the western obese population (RR=6.91, 95%CI 5.59 to 8.56) than the eastern obese population (RR=4.19, 95%CI 2.93 to 5.99). Based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE), the quality of the included studies on T2DM developed by overweight and obesity was low and medium respectively. Conclusion Overweight and obesity can increase the onset risk of T2DM which is higher in the female and western obese populations than the male and eastern obese populations respectively.
