Journal of Interventional Radiology 1994;0(04):-
Objective To investigate the correlated issues in the stenting treatment of major airway constriction. Methods Nineteen cases of major airway stenting procedure were studied retrospectively. The clinical choice of stents of different advantages or deficiencies were discussed. The importances of intravenous anesthesia supporting, life parameters monitoring during the procedures and the prevention of complications were analysed. Results Under intravenous and local anesthesia, 19 Wallstents had been successively placed and relieved 19 cases of major airway constrictions due to malignant or benign diseases (15 of tumors, 3 of tuberculosis, 1 of tracheomalacia). Intravenous anesthesia and life parameters monitoring had made the procedures more safe and precise. Conclusions Major airway stenting is an reliable method for relieving trachiobronchial stenosis; and intravenous anesthesia supporting and life parameters monitoring guarantee the satisfactions of procedures.
2.Experimental investigation of Zhixie recipe on small intestinal motion and absorption
International Journal of Traditional Chinese Medicine 2012;34(10):896-897
Objective To investigate the effects and mechanism of Zhixie recipe on small intestinal motility of rats and absorption ability of rabbits.MethodsThree groups of rats,one was fed with distilled water,the another two were fed with Zhixie recipe liquid of 1 g/ml and 2 g/ml.Then all three groups were fed with ink,and the moving distance of the ink in small intestines was measured to check the small intestinal motility; Three mixtures of Zhixie recipe liquid and desktop solution with 0%,5% and 10% Zhixie recipe liquid were injected into rabbits,the Chloride ion concentration in small intestines was measured to check the absorption ability.ResultsThe average moving distance percentage of ink in the small intestines of the three groups of rats was 52.55% ( SD =8.24),54.35% (SD =12.53 ) and 59.45% ( SD=14.17) of the total intestine length respectively.It showed that Zhixie recipe had no influence on small intestinal motility (P>0.05) ; Small intestines absorption experiments revealed that the small intestinal absorption ability was quite different between the rabbits with desktop solution and the rabbits with mixtures of Zhixie recipe liquid and Desktop solution(5% and 10%),with x2=6.92 and 46.18,P<0.01.The mixtures with 5% and 10% Zhixie recipe liquid improved the small intestinal absorption ability,and the effect of the mixture with 10% was even stronger.Conclusion Zhixie recipe showed no influence on small intestinal motility,but it improved the small intestinal absorption ability.

China Pharmacist 2016;19(7):1307-1308,1316
Objective:To investigate the efficacy of montelukast in the treatment of children with asthma and its influence on the serum levels of metalloprotease-9 (MMP-9) and metal protease inhibitor-1 (TIMP-1).Methods:Totally 90 cases of asthma children were selected and divided into the control group and the observation group with 45 ones in each .The control group was treated with the conventional symptomatic treatment , and the observation group was treated with montelukast chewable tablets additionally , and the treatment course was 8w.The effectiveness adverse reactions were compared between the groups , and the lung function indices and the changes of MMP-9 and TIMP-1 levels of the two groups were compared as well .Results: The total effective rate of the observation group (93.33%) was significantly better than that of the control group (P<0.05).After the treatment, the levels of FEV1 and PEF were significantly higher than those before the treatment in the two groups , the levels of MMP-9 and TIMP-1 were notably lower than those before the treatment in both groups , and the changes in the observation group were more significant than those in the control group (P<0.05).There were no adverse drug reactions in both groups .Conclusion:Montelukast combined with the conventional therapy can down-regulate the serum levels of MMP-9 and TIMP-1 and inhibit airway remodeling resulting in improved curative effect with high safety.
5.Study on the Relationship between the Perioperative Application of Antibiotics in Caesarean Operation and Neonatal Hyperbilirubinemia
China Pharmacy 2015;(23):3273-3274,3275
OBJECTIVE:To investigate the relationship between the perioperative application of antibiotics in caesarean opera-tion and neonatal hyperbilirubinemia,and to provide reference for reducing the incidence of neonatal hyperbilirubinemia. METH-ODS:264 cases of cesarean section women were randomly divided into control group and observation group,with 132 cases in each group. Control group was given antibiotics after operation,and observation group was given prophylactic application of antibi-otics before operation,and equivalent dose of intravenous injection after operation. Postoperative maximum and average tempera-ture,white blood cell(WBC),neutrophils(NEUT),complications and economic index were compared between 2 groups after op-eration. RESULTS:There was no statistically significant difference in postoperative maximum and average temperature,WBC count,NEUT proportion,wound infection and fever rate between 2 groups (P>0.05). The costs of medication,drug dosage per capita,hospital stay and the incidence of neonatal hyperbilirubinemia in observation group were significantly lower than in control group,with statistical significance (P<0.05). CONCLUSIONS:The perioperative standard use of antibiotics in caesarean opera-tion could effectively reduce the incidence of postoperative neonatal hyperbilirubinemia and hospitalization cost,and cut down treat-ment time. It also has a high economic value and worthy of promotion.

Objective To assess the association between the depth of trophoblastic penetration into the tubal wall with serum concentrations of vascular endothelial growth factor (VEGF) and β-human chorionic gonadotropin (β-HCG). Meth-ods Eighty patients with a diagnosis of tubal pregnancy in the ampullary region underwent radical surgical treatment (sal-pingectomy), were included in this study. The serum levels of VEGF andβ-HCG were detected on the day of surgery. The se-rum level of VEGF was measured by ELISA. The serum level ofβ-HCG was quantified with a two-site immunofluorimetric assay based on the direct sandwichtechnique. Histological material was stained with Masson's trichrome to identify muscular fibers. Immunohistochemical staining was used for human placental lactogen (hPL) to identify intermediate trophoblast and determine the depth of trophoblastic invasion into the tubal wall. The ampullary pregnancies were classified histologically ac-cording to the depth of trophoblastic infiltration into the tubal wall. Results The mean serum values of VEGF andβ-HCG were significantly lower in patients with stage I tubal infiltration than those of stageⅡ, and which were significantly lower in patients with stageⅡthan those in stageⅢ(P<0.05). The threshold serum value of VEGF was 308.6 ng/L, the sensitivity was 100.0%and the specificity was 92.6%for stageⅠand stageⅡ. The threshold serum value of VEGF was 431.9 ng/L, the sensitivity was 79.3%and specificity was 79.2%for stageⅡandⅢ. The threshold serum value ofβ-hCG was 2 509.6 IU/L, the sensitivity was 91.7%and specificity was 81.5%for stageⅠand stageⅡ, and levels of 13 142.6 IU/L, 72.4%and 95.8%for stageⅡand stageⅢ. Conclusion The depth of trophoblastic penetration into the tubal wall is associated with maternal serum concentrations of VEGF andβ-HCG, which can be used as the evaluation index for histological staging of trophoblas-tic tissue infiltration.

Objective To investigate angiographic manifestations and interventional treatment of renal arteriovenous fistulas. Methods Renal arterial angiographies were performed in 20 patients from multiple hospitals.These patients suffered from repeatedly intermittent hematuria,but ultrasound,KUB,IVU,CT and endoscopy could not contribute to the diagnosis.The angiographic manifestations and treating procedure were analyzed. Results All the 20 cases were diagnosed as renal arteriovenous fistula by means of angiography.According to the image manifestations,these cases were classified into three types:(1)deformed branches and shunt in 11 cases;(2)high discharge shunt without deformed banches in 4;(3)concealed shunt showed by superselective segmental artery angiography but negative by renal artery angiography in 5.All fistulas of the 20 cases were successfully embolized with different materials including gelfoam,sodium morrhuate,ethanol,PVA,TH-glue,coils,etc. Conclusions Superselective renal angiography and embolization are the most important and effective tools for diagnosis and treatment of renal arteriovenous fistula.
