This paper reported that bronchial artery embolization(BAE)had been used to treat 35 non tumorous patients who suffered from recurrent hemoptysis or acute severe hemoptysis after the given medical treatment was proved uneffective in 35 patients,7 patients had recurrent hemoptysis during 1.5～19 months postoperatively and were treated by BAE again,and there was no recurrence of hemoptysis during 7～34 months follow-up.Therefore, the authors considered that repeated BAE was still effective in treating recurrent hemoptysis.

Objective To analyze the epidemiological characteristics of public health emergencies and the situation of report and control of public health emergencies in Qijiang District of Chongqing M unicipality during 2009-2013 to provide a scientific ba‐sis for the prevention and control of public health emergencies .Methods The descriptive epidemiology method was used to analyze the directly network reported data of the public health emergencies in Qijiang District during 2009-2013 from the National Emer‐gency Public Health Emergencies Reporting Management System .Results Total 47 public health emergencies were reported in Qi‐jiang District during 2009-2013 ,including 994 cases of caused disease and 1 case of death (food poisoning) .Most of the emergen‐cies were caused by infectious diseases events ,accounting for 82 .78% (39/47) ,food poisoning and other public health emergencies (dog bites) accounted for 2 .13% (1/47) and 14 .89% (7/47)respectively .Respiratory disease events accounted for 78 .72% (37/47) of total infectious diseases events ,the majority were influenza A (H1N1) flu and epidemic parotiditis .The high‐incidence seasons were from April to May(accounting for 34 .04% )and October(40 .42% ) .The most cases happened to the school (especially infec‐tious diseases) ,accounting for 80 .85% of the total events .Conclusion The respiratory infectious disease in the prevailing season is the priority of prevention and control on public health emergencies in Qijiang District .Attentions should be highly paid to the pre‐vention and control of public health emergencies (especially in rural schools);meanwhile ,the dog management and propaganda of prevention and control knowledge should be strengthened to effectively eliminate the potential of hydrophobia .

Objective To summarize the clinical experience of serious hyponatremia resulted from applying pitnitrin to massive hemorrhage of gastrointestinal tract patients.Methods we used pitritrion on 2460 such patients and examined some symptoms of the digestive tract and nerve system,monitoring the dynamic state of blood sodium.Results The re- suits reveal that patients in 30 cases turned out to suffer from serious hyponatremia,whese sodium in the serum appeared less than 110 mmol/L,which was 1.22% of the rest subjects'.The relevant symptoms included nausea,vomit,spoor,coma and twitch etc.Following remedies included liquid supply with a high-concentrated sodium,ceasing using pituitrin,in- take of salute foods,and dynamic monitoring on the state of sodium in the serum.All patients recovered in 1 to 3 days without a single failure.Conclusion Thus we reach this conclusion:When applying pituitrin to massive hemorrhage of gastrointestinal tract patients,the above mentioned symptoms should be closely examined,and blood sodium should be timely monitored so that proper treatment should arrive in time.

Objective To explore the effect of osthole on mast cells and expression of STAT5 gene and protein in them. Methods Passive cutaneous anaphylaxis was made in mice to copy eczema model, then the allergic mast cells were separated, and the ovalbumin was used to induce allergy of mast cells. Different concentrations of osthole were used to intervene the sensitized mast cells.Then the sensitized mast cells were divided into blank control group, osthole high-dose group and low-dose group.At the end of the experiment, morphology of the mast cells was detected by immunofluorescence technology.MTT assay was used to detect the influence of drugs on mast cells proliferation. RT-PCR and Western blotting were used to detect the expression of STAT5 gene and protein. Results As compared with blank control group, the number of mast cells in the osthole groups was significantly reduced, cells and nuclei obviously shrank, even apoptosis of some cells could be observed; the inhibition rate of mast cells in osthole groups was significantly increased in concentration-dependent manner ( P<0. 01 ) . As compared with blank control group (2.16±0.57), gene expression of STAT5 was significantly decreased in osthole high-dose group (0.59±0.12) and low-dose group (0.82±0.13) (P<0.01).The protein expression of STAT5 was also significantly decreased in osthole high-dose group and low-dose group as compared with blank control group (P<0.01). Conclusion Osthole can inhibit the proliferation of sensitized mast cells, and reduce the expression of STAT5 gene and protein.

Objective To discuss the value of amnionic fluid lamellar body count(LBC) as a predictor of fetal lung maturity. Methods Amnionic fluid was obtained during the cesarean section of 41 normal term pregnancies. LBC was performed on each specimen, and lecithin-sphingomyelin(L/S) ratio was detected simultaneously. Results (1)Amnionic fluid LBC was (86?43)?10 3 (72.5?10 3~99.4?10 3) in normal term pregnancy. (2) Positive correlation was shown between the amnionic fluid LBC and L/S ratio(r=0.66,P=0.001). Conclusion The LBC is a rapid and accurate method to determine the fetal lung maturity.

Objective To compare four pretreatment methods of human plasma coagulation factor Ⅷ( FⅧ) before column purification.Methods Cryoprecipitate was dissolved in Tris , before the supernatant was treated with glycine precipitation, PEG precipitation, acid precipitation and aluminum hydroxide gel adsorption , respectively.Activated partial thromboplastin (APTT) was used to measure the activity of the supernatant clotting FⅧ after treatment.The total activity recovery and specific activity of the final samples were used to weigh the efficacy of those methods .The purity of the intend-ed protein was estimated by non-reducing SDS-PAGE electrophoresis .Results Total activity recovery of glycine precipitati-on was the highest (94.00%±7.60%), followed by that of acidic precipitation (89.47%±2.60%) and PEG precipita-tion (80.92%±9.67%) methods.The lowest was aluminum hydroxide gel adsorption (78.65%±7.52%).Glycine precipitation and PEG precipitation could more effectively remove contaminating protein than acid precipitation and aluminum hydroxide gel adsorption .Treated by four different methods , the specific activity of FⅧ of glycine precipitation sample was the highest (0.6856 ±0.1258 IU/mg), followed by PEG precipitation (0.5773 ±0.0787 IU/mg) and acidic precipitation (0.3885 ±0.0301 IU/mg).The specific activity of aluminum hydroxide gel adsorption was the lowest (0.2879 ±0.0472 IU/mg).Conclusion PEG precipitation is more effective for the actual production process than the other three methods .

Objective: To analyze the risk factors on acute respiratory dysfunction caused death in patients after type A aortic dissection surgery.
Methods: A total of 223 patients who received aorta replacement surgery in our hospital from 2010-01 to 2012-12 were retrospectively studied. 80 patients suffered from post-operative acute respiratory dysfunction including 61 male and 19 female with the mean age of (49.2 ± 11.6) years. Those patients were divided into 2 groups as Death group, n=18 and Survival group, n=62. We analyzed the most relevant risk factors for death, such as gender, age, histories of smoking, diabetes, hypertension, Marfan syndrome;pre-operative acute or chronic dissection, hypoxemia, mal-perfusion, LVEDD and LVEF;CPB time, aortic-clamping time;post-operative ICU retention time, mechanical ventilation time, permanent neurologic dysfunction, pulmonary infection, MACE, renal failure, hypohepatia, septicemia and wound mal-healing, et al.
Results: The early post-operative (< 3 days) respiratory dysfunction rate was 35.8% and the mortality was 22.5%(18/80). The relevant risk factors of death included female gender (P=0.019), haemorrhage (P<0.01), mechanical ventilation time (P=0.011), permanent neurologic dysfunction (P=0.013), pulmonary infection (P=0.001), MACE (P=0.022), renal failure (P<0.01), hypohepatia (P<0.01) and septicemia (P=0.001). Female gender and renal failure were the independent risk factors for respiratory dysfunction caused death in patients after type A aortic dissection surgery.
Conclusion: The occurrence and mortality were high in patients after type A aortic dissection surgery especially in those with female gender and post-operative renal failure.
