Objective To investigate the indication, occasion and risk predication of cesarean hysterectomy and interventional treatment. Methods The clinical data of 9 patients with low cesarean section postpartum hemorrhage that underwent hysterectomy after interventional treatment from January 2012 to January 2013 were analyzed which included surgical indication, disease characteristics, procedure time, bleeding volume and other parameters. Results The most common surgical indication for cesarean that caused postpartum hemorrhage was dangerous placenta previa, accounting for 56%, followed byⅢdegree of placental abruption and preeclampsia. The surgical bleeding of cesarean accounted for 62%-70%of the total amount of bleeding. The total time of rescue was 7.4 ± 1.4 hours. The total amount of bleeding was 7 100 ± 2 250 mL. The occurrence of coagulation disorder was significantly correlated with surgical time and amount of blood loss. Conclusion For postpartum hemorrhage caused by cesarean section with risk factors such as scar uterus, placenta previa, placental abruption, many pregnant prolific and others, we must relax indications of hysterectomy. With future treatment potential, the early intervention of postpartum hemorrhage also plays an important role in reducing hysterectomy rate, reducing intraoperative and postoperative blood loss.

Background Thyroid-associated ophthalmopathy (TAO) is a kind of clinically common and incurable ocular disease,and its incidence is at top place.The etiology and pathologic mechanism of TAO are still unknown because of shortness of replicative animal models and difficulty to acquire the ocular tissues in the early stage of the disease.To better understand the pathogenesis of TAO and investigate effective treatable measures, an appropriate animal model should be developed.Objective This study was to immunize female BALB/c mice with the recombinant plasmid of human thyroid-stimulating hormone receptor (TSHR) extracellular domain in cationic liposomes for the establishement of TAO models.Methods Thirty-two 6-to 8-week-old female BALB/c mice were randomly assigned to four groups according to computer random allocation.pcDNA3.1 +/hTSHR289 of 100 μg in an adjuvant cationic liposomes was injected via anterior tibialis muscle and peritoneal cavity separately in the recombinant plasmid injection group in 0, 3,6 weeks, and pcDNA3.1 or cationic liposomes was injected in the liposomes injection group or the blank plasmid group in the same way, respectively, and normal saline solution was injected in the blank control group.Body weight of the mice was measued before and 1 month,2,3 and 4 months after initial injection.The manifestations were observed after modeling.The mice were sacrificed 17 weeks after initial injection,and the histopathology examination was carried out on the thyroid gland and orbital tissue.The heart blood was collected from the mice,and serum contents of total thyroxin 4 (TT4) and thyroid-stimulating hormone (TSH)were assayed by ELISA.Results Protrusion, eyelid swell and keratitis occurred in 12 eyes of 6 mice in the recombinant plasmid injection group after immunization.A significant difference in the body weight of the mice was found among the blank control group, blank plasmid group, liposomes injection group and recombinant plasmid injection group (Fgroup =3.425, P =0.028), and the body weight was considerably reduced in the recombinant plasmid injection group in comparison with the blank control group, blank plasmid group,liposomes injection group (Ftime =0.838 ,P=0.023).The serum levels of TT4 were (7.75±1.00), (7.96±0.76), (6.76±1.10) and (4.43±2.88) μg/dlin the blank control group, liposomes injection group, blank plasmid group, and recombinant plasmid injection group, and those of TSH were (6.36±2.58),(4.83±3.96),(6.63±1.71) and (1.60 ±1.76) ng/ml, showing significant differences among the groups (F =7.150, P＜0.001;F =5.521, P＜0.01) , and the serum levels of TT4 and TSH were remarkably lower in the recombinant plasmid injection group than those of the blank control group,liposomes injection group and blank plasmid group (all at P ＜ 0.05).Histopathology revealed the lymphocyte infiltration of thyroid gland in 6 mice and proliferation of orbital adipose tissue, infiltration of lymphocytes and mastocytes,deposition of hyaluronic acid as well as swell, breakage and inflammatory cell infiltration of extraocular muscle in 15 eyes of the recombinant plasmid injection group.Conclusions A murine model of TAO can be successfully induced by immunization with recombination plasmid pcDNA3.1 +/hTSHR289 and cationic liposomes.The histopathology characteristics and ocular findings of the animal models are similar to human TAO.

Objective To explore the risk factors of asthma in children with bronchiclitics.Methods One hundred and two cases hospita-lized patients with bronchiolitis were analyzed and followed-up for 2-7 years,items of follow-up included sex,morbidity age,food feeding,severity of disease,atopy physique,family history of atopy/asthma,environment exposure,passive smoking,and so on.The factors were carried on the Logistic regression analysis to determine the influence on later years to having recurrent asthma.Results Forty-seven cases had transferred asthma,which was remarkably higher than the domestic urban survey data(0.12%-3.34%).The multi-factors Logistic regression analysis demonstrated that environment(OR 6.099,95%CI 1.824～20.396),passive smoking(OR 49.222,95%CI 8.219-294.774),atopy physique (OR 45.548,95%CI 6.799-305.117)and family history of atopy/asthma(OR 47.921,95%CI 8.626-266.226)were the risk facter of asthma( Pa

To observe the efficacy and safety of mini-percutaneous nephrolithotomy with Neodymium: Yttrium Aluminum Garnet (Nd-YAG) laser in the treatment for upper urinary tract stones, from December 2005 to September 2006, 31 patients with renal stones, 15 patients with ureteral stones and 7 patients with renal and ureteral stones underwent mini-percutaneous nephrolithotomy with Nd-YAG laser by combination of rigid ureteroscope and flexible ureteroscope under B-ultrasound guidance. Clinical data including operation time, lithotripsy time, complications and stone-free rate were analyzed retrospectively. Our study showed that the percutaneous renal access (F14-F18) was successfully established under B-ultrasound guidance in all cases. Immediate phase: lithotripsy was performed in 47 cases through single tract, and in one case through two tracts. Delayed phase II lithotripsy was done in 5 cases of renal stones. Operation time ranged from 55 to 180 min with an average time of 100+/-15 min. Lithotripsy time was from 25 to 135 min and the average lithotripsy time was 65+/-11 min. No severe complications occurred in our series. Complex renal stones were cleared in 34 of 38 cases (89.5%). All ureteral stones were completely removed in 15 cases (100%). It was concluded that mini-percutaneous nephrolithotomy with Nd:YAG laser for the treatment of upper urinary tract stones by combination of rigid ureteroscope and flexible ureteroscope has the advantages of effectiveness, mini-invasion, shorter operative time and safety.
