过期妊娠与新生儿窒息及围生儿死亡

目的 探讨过期妊娠与新生儿窒息及围生儿死亡的关系. 方法 回顾性分析比较343例过期妊娠孕妇与343例同期足月妊娠孕妇的临床资料,分析孕周、羊水量、胎盘成熟度、分娩方式、产程等与新生儿窒息及围生儿死亡的关系. 结果过期妊娠组胎儿窘迫、新生儿窒息及围生儿死亡与足月妊娠组比较,差异均有统计学意义(P<0.05);过期妊娠随孕周的增加、羊水量减少、产程异常新生儿窒息的发生率明显增加;过期妊娠分娩方式中人工助产新生儿窒息率最高(51.9%),自然分娩较低(13.3%),剖宫产最低(9.9%);产程异常者新生儿窒息率(38.2%)及围生儿死亡率(6.7%)均明显增加. 结论过期妊娠可导致胎儿慢性缺氧及营养不良,加强产前监护,及时了解胎儿宫内安危,适时终止妊娠,可降低新生儿窒息和围生儿死亡率.     

外用他克莫司和吡美莫司的安全性

他克莫司和吡美莫司是新型钙调磷酸酶抑制剂药物,其外用制剂可用于治疗特应性皮炎。近年来,对这两种药物的安全性存有争议。现有的资料表明,外用他克莫司和吡美莫司安全性高,不引起皮肤萎缩,经皮吸收极少,无明显的系统免疫抑制作用,不会引起皮肤或系统的感染和肿瘤的发病率升高。

浆膜受侵的结直肠癌术后腹腔化疗联合静脉化疗的临床研究

Objective To compare the clinical efficacy of postoperative intraperitoneal chemotherapy combined with systemic chemotherapy to systemic chemotherapy alone for serosa-involved colorectal cancer. Methods According to the criteria of serosa-involving in colorectal cancer, 332 cases were divided into 2 groups prospectively without randomization. Study group (n=166) was treated with intraperitoneal chemotherapy combined with systemic chemotherapy, and control group (n=166) with systemic chemotherapy alone. Incidence of local recurrence, peritoneal metastasis, hepatic metastasis, other distant metastasis and 3-year, 5-year overall survival (OS) rate of two groups were compared. Results 3-year and 5-year OS rates of stage Ⅱ B in study group were similar to those in control group (χ2=0.612,P=0.434). The above rates of stage Ⅲ in study group were higher than those in control group (χ2=3.989,P=0.046). Either the study group or the control group, the 3-year and 5-year OS rates of patients undergone laparoscopic surgery or open surgery were similar (P=0.839, P=0.172). Incidences of local recurrence, peritoneal metastasis and hepatic metastasis in study group were 1.9%, 3.8% and 3.8% respetively, lower than those in control group (8.2%,9.5% and 10.1%,P<0.05). Distant metastasis rate in study group was similar to that in control group. In study group, intraperitoneal chemotherapy regimen with Oxaliplatin had lower rates of peritoneal metastasis and hepatic metastasis as compared to that with Cisplatin (0.9% vs 8.8% ,P=0.019), while the incidences of local recurrence and other distant metastasis were similar. Conclusions Postoperative intraperitoneal chemotherapy combined with systemic chemotherapy improves 3-year and 5-year overall survival rates in patients with stage Ⅲ serosa-involved colorectal cancer, and decreases local recurrence, peritoneal metastasis and liver metastasis rate, especially when intraperitoneal chemotherapy regimen contains Oxaliphtin. Comparing with open surgery, laparoscopic surgery dose not improve 3-year and S-year overall survival rates in patients receiving combined chemotherapy or systemic chemotherapy alone.

Electrophysiological study on differentiation of rat bone marrow stromal stem cells into neuron-like cells in vitro by edaravone

To explore the electrophysiological proper-ties of differentiation of rat bone marrow-derived stromal stem cells (rBMSCs) to neuron-like cells in vitro by edaravone, a new type of free radical scavenger. Methods: Stromal stem cells were separated from rat bone marrow with Ficoll-Paque reagent and expanded in different culture medium in vitro, rBMSCs were induced by edaravone containing serum-free L-DMEM. Morphologic observation and Western blot analysis including the ex-pression of Nav1.6, Kv1.2, Kv1.3, Cav1.2 were performed, and whole patch-clamp technique was used. Results: Cyton contraction and long processes were shown in differentiated stromal stem cells. Nav1.6, Kv1.2, Kv1.3 and Cav1.2 were expressed in both differentiated and undifferentiated cells. However, the expression of channel proteins in differentiated cells was up-regulated. Consistently, their resting potential and outward currents were also enhanced in the differentiated cells, which was especially significant in the outward rectifier potassium current. Conclusion: In vitro, neuron-like cells derived from rBMSCs, induced by edaravone, possess electrophysiologi-cal properties of neurons.
