Objective: To establish the quality standards of Reduning Injection (RI) based on UV fingerprint, and improve the quality standards of RI. Methods: Full wavelength UV-vis spectrophotometer was used to scan the 15 batches of RI, a reference fingerprint was established, correlation coefficient method was used to calculate RI sample fingerprint and control fingerprint similarity, and the 14 batches of samples were verified. Results: The five batches of RI were within the validity period, their UV fingerprints were in line with the requirements, similarity was all above 0.902, while the absorbance values were in the ranges of 0.693-0.781 (323 nm), 0.323-0.370 (267 nm), 0.957-1.067 (236 nm), 0.902-1.013 (226 nm), 0.953-1.075 (218 nm), and 0.926-1.052 (211 nm); In addition the expired nine batches of RI, similarity is less than 0.902 or the absorbance value does not meet the standard. Conclusion: UV fingerprint method can be used as a simple and accurate method of quality evaluation for the quality control of RI.

A 61-year-old patient with type I diabetes, diabetic nephropathy, thyroid hypofunction, chronic renal insufficiency anemia period, class IV heart function. During kidney dialysis, a little bleeding when puncture needle punctured the right common carotid artery, bleeding stopped after compression hemostasis. One week later, the patient complained of swollen neck, pain and difficult breathing. Ultrasonic examination suggested that local eminence beside the right common carotid artery, echoless and vascular interlinked; CDFI blood flow signal appeared the artery frequency spectrum, eddy current. Enhanced CT prompted right common carotid artery pseudoaneurysm, the contrast medium extravasated. The patient was diagnosed right common carotid artery pseudoaneurysm.

OBJECTIVE: To establish an HPLC method for the content determination of prostaglandin A1 and prostaglandin B1 in Alprostadil for injection.METHODS: The determination was performed on Alltech Alltima C18 column with mobile phase consisted of phosphate puffer(pH=6.3)-acetonitrile-methanol(70 ∶ 25 ∶ 5) at a flow rate of 1.5 mL? min-1.The detection wavelength was set at 196 nm.The column temperature was set at room temperature and the injection volume was 20 ?L.RESULTS: The prostaglandin A1 and prostaglandin B1 were well separated from main component and other impurities.The linear range of prostaglandin A1 and prostaglandin B1 were 0.175～19.00 ?g?mL-1(r=0.999 7) and 0.23～19.90 ?g?mL-1(r=0.999 2).The contents of prostaglandin A1 in 3 batches of samples were 4.7%,4.9% and 4.3%,and the contents of prostaglandin B1 in 3 batches of samples were 0.6%,0.8% and 0.5% respectively.CONCLUSIONS: This method is proved to be simple,specific and suitable for the content determination of related substances in Alprostadil for injection.

Objective To compare the effects of different methods of honey sunburn on the contents of calycosin and formononetin in Hedysari Radix; To provide the basis for the establishment of the optimum processing technology. Methods By frying (traditional method), baking, and microwave methods put Hedysari Radix under honey sunburn. Agilent HC-C18 column (4.6 mm × 250 mm, 5 μm) was used; the mobile phase was acetonitrile-0.01% phosphoric acid solution, gradient elution (0–12 min, 30%–33% acetonitrile; 12–13 min, 31%–40% acetonitrile; 13–25 min, 40% acetonitrile) with velocity of 1.0 mL/min; detection wavelength was 248 nm;the column temperature was 30 ℃; sample volume was 10 μL. Results There was statistical significance in the contents of calycosin and formononetin of different methods of honey sunburn for Hedysari Radix. Among them, the contents of calycosin and formononetin in Hedysari Radix processed by honey roast were the highest, 7.9116 and 49.6996 μg/g, respectively; the contents of calycosin and formononetin in Hedysari Radix processed by traditional method were the lowest, 4.7767 and 37.2910 μg/g, respectively; the contents of calycosin and formononetin in raw Hedysari Radix and Hedysari Radix by honey microwave method were the same, 5.0802, 42.7989 μg/g, and 3.9839, 42.3145 μg/g, respectively. Conclusion Different honey sunburn methods for the contents of calycosin and formononetin in Hedysari Radix have certain effects, and honey roast method is the optimum method.

Spinal biomechanics, especially the range of spine motion,has close connection with spinal surgery. The change of the range of motion (ROM) is an important indicator of diseases and injuries of spine, and the essential evaluating standards of effect of surgeries and therapies to spine. The analysis of ROM can be dated to the time of the invention of X-ray and even that before it. With the development of science and technology as well as the optimization of various types of calculation methods, diverse measuring methods have emerged, from imaging methods to non-imaging methods, from two-dimensional to three-dimensional, from measuring directly on the X-ray films to calculating automatically by computer. Analysis of ROM has made great progress, but there are some older methods cannot meet the needs of the times and disappear, some classical methods such as X-ray still have vitality. Combining different methods, three dimensions and more vivo spine research are the trend of analysis of ROM. And more and more researchers began to focus on vivo spine research. In this paper, the advantages and disadvantages of the methods utilized recently are presented through viewing recent literatures, providing reference and help for the movement analysis of spine.

Human tissue kallikrein-binding protein (Kallistatin, KAL), a secretory protein that participates in the regulation of multiple signaling pathways by binding to the extracellular receptor, however, at present has not been reported about the intracellular activity, and whether it has the similar biological activity with extracellular activity. Here we constructed no signal peptide KAL (NSK) into the adeno-associated virus vector to explore the intracellular activity of KAL. Both the endothelial cell and lung cancer cells could express KAL, but not secreted after rAAV2-NSK transfection. The proliferation and migration of human umbilical vein endothelial cells (HUVECs) were inhibited, but the apoptosis rate was not affected. The proliferation rates, mobility and tubule formation of all the three tested lung cancer cells, such as NCI-H446, NCI-H460 and A549, were inhibited to different extents. This cellular study not only confirmed the intracellular activity, but also suggested it may serve as a kind of "balance factor" in multi-targeted controlling, which may provide a new train of thoughts to explain the regulatory contradiction in PI3K-Akt signaling pathways by KAL.

Objective To evaluate the effects of rapamycin combined with rosiglitazone on lung injury in septic rats.Methods One hundred and twenty healthy male Wistar rats were randomly divided into 5 groups (n =6 each):sham operation group (group S); cecum ligation and punture (CLP) group; rapamycin group (group RPM) ; rosiglitazone group (group RGZ) ; rapamycin plus rosiglitazone group (group RPM + RGZ).The rats were anesthetized with intraperitoneal 10% chloral hydrate 100 mg/kg.Sepsis was induced by CLP in groups CLP,RPM,RGZ and RPM + RGZ.At 30 min before CLP,rapamycin 0.4 mg/kg was injected subcutaneously in RPM group,rosiglitazone 0.3 mg/kg was injected via the femoral vein in RGZ group,and rapamycin 0.4 mg/kg was injected subcutaneously and rosiglitazone 0.3 mg/kg was injected via the femoral vein in group RPM + RGZ.While the equal volume of normal saline was given instead in CLP group.Six rats were sacrificed at 2,6,24 and 48 h after CLP in each group,and lungs were removed and cut into sections which were stained with haematoxylin and eosin and examined under microscope.The pathological changes of lungs were scored.The myeloperoxidase (MPO) activity and signal transducer and activator of transcription 3 (STAT3)-DNA binding activity in lung tissues were measured.Results Compared with group S,the pathological scores,MPO activity and STAT3-DNA binding activity were significantly increased in groups CLP,RPM,RGZ,RPM + RGZ (P ＜ 0.05).The pathological scores,MPO activity and STAT3-DNA binding activity were significantly lower in groups RPM,RGZ and RPM +RGZ than in group CLP,and in group RPM + RGZ than in groups RPM and RGZ (P ＜ 0.05).Conclusion Rapamycin combined with rosiglitazone offers additional benefit to attenuating lung injury induced by sepsis over rapamycin or rosiglitazone alone,and inhibition of activation of STAT3 pathway is involved in the mechanism.
