Objective To investigate the role of hepatic Kupffer cells in acute hemorrhagic necrotizing pancreatitis associated lung injury(AHNP LI) and the therapeutic effects of gadolinium chloride(GdcI_3). Methods Forty-two Wistar rats were randomly divided into four groups:(I) sham operation group;(II) AHNP group;(III) Gdcl_3 (protection) group(Gdcl3 10mg/kg);(IV) Gdcl_3control group(Gdcl_3 10mg/kg).In the sham operation group, the (abdominal) vescera were shifted around for several times and the abdomen was closed.The AHNP model was induced by retrograde intraductal administration of 5% sodium taurcholate(1ml/kg,0.1ml/min).In the Gdcl_3 protection group,Gdcl_3 solution was admmistered by caudal vein injection one day before the AHNP model was made.In these 3 group of animals,specimens were obtained in order at 3h and 6h postoperatively:(1)Blood was withdrawn from the abdominal aorta to determine serum amylase,TNF?,IL-1(in addition,in the sham operation group,blood AST and ALT were determined);(2)A portion of liguefied right lung was obtained to determine MPO;another portion was fixed with 10% formalin for tissue pathological examination;(3)Bronchoalveolar lavage fluid of excised left lung was obtained ,and then alveolar macrophages were isolated,collected and purified.After removal of their nuclear (proteins),the alveolar macrophages were tested to determine NF-?B activation with the use of chemical illumination ELISA method;and (4)pancreatic tissue was reserved for pathological examination.In the Gdcl_3 control group, Gdcl_3 was administered by caudal vein injection,the animals were sacrificed 24h later,and blood was obtained to determine blood AST and ALT. Results In the Gdcl_3 prevention group,the level of MPO in lung tissue,serum (levels) of TNP? and IL-1,and NF-?B activation of alveolar (macrophages) were all significanfly reduced as compared with the AHNP model group(in all,P

Objective To establish the fingerprint detecting standard for Tanreqing NaCl Injection. Methods Using baicalin as reference substance to calibrate the common peaks by HPLC-ELSD. According to the technical requirements on fingerprint of traditional Chinese medicine injection, their relative retention times and peak area ratios were calculated and the similarity of ten batchs of samples was determined. Results On the basis of systematic methodology, ten batches of injection samples were tested and analyzed so as to establish HPLC fingerprint for the injection. Conclusion The relative retention times and peak area ratios of 16 common peaks on HPLC fingerprint all conform to the requirement. So the established fingerprint can be used as the one of important foundations for quality control of Tanreqing NaCl Injection.

AIM: To establish a quick,accurate,sensitive method for analysing sildenafil citrate illegally added into traditional Chinese medicinal preparation. METHODS: The ultra performance liquid chromatography-quadrupole mass spectrometry method was used.Electrospay ionization(ESI) source was applied and operated in the positive and negative ion mode.The compound of sildenafil citrate illegally added into traditional Chinese medicinal preparations were identified according to the spectrum,chromatographic behavior and mass spectral data by comparison with those of reference substance. RESULTS: Sildenafil citrate was found in two formulations of three. CONCLUSION: The method is selective and sensitive and can be used to detect the sildenafil citrate illegally added into traditional Chinese medicinal preparations.

OBJECTIVE To evaluate the safety and clinical efficacy of cefoperazone/sulbactam in the treatment of biliary tract infections.METHODS In this prospective multicenter study,159 hospitalized patients with biliary tract infections received cefoperazone/sulbactam,and the clinical and bacteriological efficacy as well as the side effects were evaluated.RESULTS The clinical effective rate of cefoperazone/sulbactam in the treatment of biliary tract infections was 86.78%.After treatment,the body temperature reduced to normal rapidly,the average time of defervescence was 3.09?1.81 days.Pathogen eradication rate was 85.71%.No adverse reactions were reported during the study period.CONCLUSIONS Cefoperazone/sulbactam can be used as one of antibiotics of choice in the initial empirical therapy for biliary tract infections.
