Objective:To observe the effect of magnesium sulfate combined with nifedipine on preeclampsia blood pressure and pregnancy outcomes. Methods:The data of 62 patients with preeclampsia were retrospectively studied. According to the treatment reg-imen, the patients were divided into the control group (30 cases) with magnesium sulfate treatment and the observation group (32 ca-ses) with magnesium sulfate combined with nifedipine treatment. The blood pressure before and after the treatment, as well as the clin-ical efficacy, pregnancy complications and pregnancy outcomes in the two groups were compared. Results:After the treatment, systolic and diastolic blood pressure of the patients in the two groups were significantly lowered when compared with those before the treatment (P<0. 05), and the decrease in the observation group was more significant than that in the control group (P<0. 05). The total effec-tive rate of the observation group was 96. 88%, which was significantly higher than that of the control group (73. 33%, P<0. 05). The incidence of uterine inertia, postpartum hemorrhage, fetal distress and placental abruption in the observation group was significant-ly lower than that in the control group (P<0. 05), and the rate of cesarean section and neonatal asphyxia in the observation group was also significantly lower than that in the control group(P<0. 05). Conclusion:Magnesium sulfate combined with nifedipine in the treat-ment of preeclampsia shows notable antihypertensive effect, which can reduce the incidence of pregnancy complications and adverse pregnancy outcomes. Therefore, the combination exhibits better efficacy than magnesium sulfate alone.

Objective To evaluate the impact of warmed and humidified CO2 on the gynecological laparoscopic operation. Methods We searched keywords related to gynecological laparoscopic and CO2 pneumoperitoneum temperature and humidity on Pubmed and Wanfang database, then analyze the postoperative pain, analgesic consumption, core temperature, operation time, length of hospital stay. Results 17 publications included into the meta analysis after screening. Compared with the standard laparoscopy, warmed and humidified CO2 can reduce postoperative pain and prevent intraoperative hypothermia. No significant difference in postoperative analgesic consumption, postoperative core temperature, duration of recovery and hospital stay, endoscope lens fog and operation time. Conclusions Only few beneficial effects on postoperative pain and core temperature have been identified in this meta-analysis, though more studies are probably needed to study the real impact of warmed and humidified CO2 for laparoscopic procedures.

According to the property of military health service positioning , armed forces all over the world invariably put military health service into combat team ranks .They want to strengthen the ties between the health system and the military system by adjusting the health command and management system in order to meet the needs of multi -level and multi-directional wartime support in the future .This paper summarizes the development of foreign ( the US.Germany and Russian Federation) and our military health command and management system , and make a detailed comparison .It may be a practical and valuable research for the current military health reform .

Rectal cancer is a common malignancy in the alimentary tract with an increasing incidence, the current treatments of which include surgery, radiotherapy, chemotherapy, and integrated comprehensive options. Sexual dysfunction, especially erectile dysfunction (ED), is one of the commonest complications in men after rectal cancer treatment and is generally attributed to the damage to the pelvic autonomic nerves. However, recent studies show that ED after rectal cancer treatment is a complex pathophysiological process associated with neurogenic, vasculogenic, and psychological factors. This article reviews the pathogeneses of ED after rectal cancer treatment in order to provide some theoretical evidence for its prevention and treatment.

Objective With the sole object of glycyrrhizic acid products,the methods were investigated for Glycyrrhiza uralensis genomic DNA transformation into Hansenula anomala by nitrogen and argon ion implantation.Methods The genomic DNA from G.uralensis was randomly transferred into H.anomala by nitrogen and argon ion bombardment.The recombined yeasts were cultured by the slant and liquid cultivation,in which the contents of glycyrrhizic acid and glycyrrhetic acid were determined by acetic anhydried-H2SO4 qualitative test and RP-HPLC determination.Results Five recombined yeast strains that produced glycyrrhizic acid and glycyrrhetic acid were obtained.After cultured in liquid medium for 96 h,the highest content of glycyrrhizic acid in the cultivation liquid was 114.49 mg/L and that of 18?-glycyrrhetic acid and 18?-glycyrrhetic acid were respectively 0.56 and 0.81 mg/L by RP-HPLC.A kind of unknown red component was found in the cultivation liquid of one recombined strain by TLC.Conclusion The recombined yeast strains of producing glycyrrhizic acid could be obtained G.uralensis genomic DNA transformation into yeast mediated by the ion implantation.

The performance evaluation of science and technology management personnels could stimulate their enthusiasm and advance the development of science.In this article,a 3-dimensional model was set up based on the evaluating criteria,the evaluating objects & the familiarity between the appraiser and the objects,which was simplified from several complicated factors necessary in the process of evaluation.Compared with the traditional methods,this 3D model sheds more light on choosing the critical factors,which helps improve the accuracy and rationality of scientific evaluation.

On the basis of generally stereotactic radiotherapy technology,intensity modulated radiation therapy technology has been developed greatly since 1990's.This technology is to improve the radiation dose distribution in the target so that the high dose area is more conformal for the three-dimentional shape of the target and the radiation dose in the normal organs and tissue around the target decreases.The characteristic of this new technology is discussed systematically in this paper.
