Objective To compare the clinical effect of three different methods in treatment of premature.Methods 150 premature patients were randomly divided into three groups,50 cases for each group,received treatments with ritodrine,magnesium sulfate plus salbutamol,or magnesium sulfate alone respectively. The tensity of uterine contraction, the interval between drug administrations and the relief of uterine contraction, the accumulative drug using time, the elongated pregnancy durations were observed for the dertermination of effectiveness. Results The group treated with ritodrine, magnesium sulfate plus salbutamol or magnesium sulfate were effective in 94%, 78%,70% of patients of each group, and it showed that ritodrine was more effective than the combination and magnesium sulfate. The intervals of drug using and contraction relief were statistically different among three groups, (2. 16 ±0. 91)h,(4. 14 ± 1.07)h,(5.12 ± 1.45) h for each(all P ＜0.05).The cumulative drug using times were(7. 04 ±1. 16) d, (7.46 ± 1.20) d, (7.06 ± 2.78) d for three groups and proved not to be statistically significant ( all P ＞0. 05 ). The elongated pregnancy durations were (22.08 ± 7.32 ) d, ( 17.42 ± 5.85 ) d and ( 11.82 ± 5.04 ) d, and significantly different in three groups ( all P ＜ 0. 05 ). Conclusion The treatment of premature with ritodrine or the combination of magnesium sulfate and salbutamol was superior to using magnesium sulfate alone.

Objective:To explore the effect of different pregnancy termination timings on the delivery safety of maternal women with pernicious placenta previa after 34 weeks.Methods:A total of 84 patients with pernicious placenta previa in Laoshan Campus of the Affiliated Hospital of Qingdao University from March 2018 to March 2019 were selected. The time of admission for delivery was more than 34 weeks. Forty women who pregnant from 34 weeks to 36 weeks of pregnancy was in the study group, 44 women who pregnant over 36 weeks was in the control group, and the pregnancy outcomes of the maternal fetuses of the two groups were compared.Results:The postpartum hemorrhage and the incidence of interventional surgery in the study group were less than those in the control group: (754.58 ± 20.35) ml vs. (1 449.26 ± 512.32) ml, 17.5%(7/40) vs. 52.27%(23/44), the differences were statistically significant ( P<0.05). The changes in hematocrit after delivery and before delivery, the amount of hemoglobin after delivery and before delivery, the rate of uterine gauze packing, the rate of Xinmupei, the rate of hysterectomy, the incidence of blood transfusion, the rate of postoperative ICU transfer between two groups hand no significant differences ( P>0.05). The incidence of neonatal birth weight less than 2 500 g and the proportion of transfer to neonatology in the study group were higher than those in the control group: 75.0%(30/40) vs. 11.36%(5/44), 80.0%(32/40) vs. 11.36%(5/44), the differences were statistically significant ( P<0.05). There was no significant differences in Apgar scores and mortality rate of newborns after birth between the two groups ( P>0.05). Conclusions:When the pernicious placenta previa is delivered after 34 weeks, the termination of pregnancy before 36 weeks of gestation is more secure for maternal and fetal health. If the fetal development rate is slow, it is necessary to appropriately extend the delivery time, but don′t exceed 36 weeks.

Objective:To summarize the experience in the postopera ti ve management of free flap transfer for the repair of the defects in head and ne ck region. Methods:Thirty three free flaps were transfere d to repair head and neck defects.The factors that may influence the survive of the flaps,and the way that may be used to handle those problems were analyzed. Result: Thirty two of the thirty three free flaps surviv ed and one was lost. The overall free flap success rate was 97.0% .Thrombosis of vein developed in 2 patients. By flap salvage, one flap survived,the other ex perienced total failure. The total postoperative complication rate was 36.4% inc luding thrombosis,infection,bleeding,wound break and so on.Corresponding treatme nt was given and all the flaps were kept except one mentioned above. Conclution:The most common complications in free flaps transfer are v essel thrombosis and hematoma. Timely salvage can prevent the necrosis of the flaps

Objective:To study the indications, surgical technique and complications of the coronal approach in the treatment of zygomatic complex fractures.Methods:Eighty-four patients with zygomatic complex fracture underwent coronal incisions for surgery. Micro or mini titanium bone plates were used to stabilize the fractured bones.In patients with endophthalmos orbital wall fractures were treated with hydroxyapatite.Follow-up was conducted for 3 months to 2 years.Results:All patients had no wound infection after operation. There was no permanent facial nerve motor function deficit. All of the patients with malocclusion regained their functional occlusion after treatment. The patients with restriction of mouth opening recovered after training. Eight patients had observable asymmetry characterized by widening of the face on the side of the injury. One patient sustained the postoperative endophthalmos beyond 3 mm.Conclusion:Coronal approach is feasible in the surgical treatment of zogomatic complex fracture.

Objective To assess the efficacy and safety of emergency transcatheter arterial embolization in the management of intractable postpartum hemorrhage. Methods Twenty-five patients with intractable postpartum hemorrhage were undertaken superselective catheterization into the bilateral internal iliac arteries or uterial arteries to find the causes and sites of bleeding through DSA and then followed by arterial embolization with gelfoam particles. Result All of the 25 patients with obstetrical bleeding were successfully controlled by TAE, the procedure lasted for 25 - 60 min, (mean 42.5 ? 4.6 min); with both catheterization and bleeding halt successful rates of 100%. Comparison of hemoglobin and heartbeat before and after the procedure showed significance(t = 29.49, P

ObjectiveTo explore the correlation between the prevalence of benign prostatic hyperplasia(BPH) and metabolic syndrome (MS)in the army elderly.Methods Totally 1 230 veterans (aged 70 years and over) from 26 military sanatorium in Shijiazhuang city were studied.The prevalence of BPH and MS was calculated.ResultsThe prevalence of BPH among the elderly was 77.0％.There was a trend of increase in the prevalence of BPH with increasing age (x2 = 50.4,P＜0.01).The prevalence of MS among the male elderly was 19.6％.MS was a risk factor for BPH(x2 =24.2,P＜0.0001).ConclusionsMS may be one of risk factors for the prevalence of BPH.

To study the level of macrophage migration inhibitory factor (MIF) in serum and the expression of MIF mRNA in abdominal subcutaneous adipose tissue,and to investigate its impact on insulin resistance and islet β-cell dysfunction in gestational diabetes mellitus (GDM).120 pregnancy women from the Affiliated Hospital of Qingdao University Medical College and Taian Central Hospital were enrolled,including 60 GDM women and 60 women with normal glucose tolerance (NGT).The serum MIF in GDM group was higher than that of NGT group [(3.58±1.02 vs 1.23±0.62) ng/ml,P<0.01].Multiple stepwise regression analysis showed that body mass index was an independent affective factor of the serum levels of MIF (r2 =0.516).The serum levels of MIF and the expressions of MIF mRNA in abdominal subcutaneous adipose tissue were significantly higher in GDM group than NGT group.MIF may contribute to insulin resistance and β-cell dysfunction in GDM.Body mass index seems to be an independent factor in affecting the serum levels of MIF.

Objective Minimally invasive technique was used in the treatment of pectus carinatum. Indication, techni-cal details and perioperative complication are discussed in this paper. Methods From March 2008 to January 2009, 6 patients with pectus carinatum underwent minimal invasive operation by using the principle of Nuss procedure in which pressure applied through a curved steel bar that was placed subcutaneously anterior to the sternum, via lateral thoracic incisions. Preoperative CT scan were performed and Hailer index was used as operative indication. Results The average age of patients was (13.6 ± 1.94) years (range, 10 - 16 years). They were all males. The mean operation time was (104.17 ± 15.63) minutes. The av-erage blood loss was (5.17±2.56) ml. The mean hospital stay was (5.67±0.82) days. Postoperative follow-up was 1 -11 months. Displacement of the stablizer was the only complication that was corrected by further fixation procedure. COnClusion The minimally invasive technique for the treatment of peetus earinatum is safe and effective with minimal complications. It can be selected as an alternative techniques and the appropriate age for this procedure is 10-16 years.
