The levels of platelet-activating factor (PAF) in cerebrospmal fluid (CSF) of patients with acute cerebral infarction were measured by the method of PAF-induced platelet aggregation quantitative analysis. The results indicated that the levels of PAF in CSF of patients with acute cerebral infarction were significantly increased (P

Point Zigong is an empirical point for acupuncture treatment of gynecological diseases. Now it is widely applied to clinical treatment and has a marked therapeutic effect. The therapeutic effect of point Zigong stimulation on gynecological diseases is closely related to the anatomical position, morphostructure specificity and action effect of the acupoint. In the present study on this acupoint, the single acupoint is seldom applied and the mechanism is not completely clear. It is needed to conduct a thoroughstudy in the future.

Objective To investigate and analyze the experience of planting and maintaining implantable venous access ports(IVAP) in management of post-operative breast cancer patients. Methods Breast cancer pa-tients receiving IVAP after surgery from Mar. 2011 to Jun. 2014 were retrospectively analyzed. The relative com-plications were documented and summarized during implanting operation. Results 468 patients received IVAP, among whom 451 patients underwent piercing implantation via right internal jugular vein, 15 patients underwent piercing implantation via right subclavian vein, and 2 patients underwent piercing implantation via left internal jugular vein. The mean cathe tering leng th was 12.8 cm for patients receiving IVAP via right internal jugular vein, ranging from 12 to 15 cm. Thereinto, 30(6.4%) patients experienced shot-term complications including 16 cases of puncture difficulty, 5 cases of accidental arterial puncture, 2 cases of extravasation, 2 cases of blood aspiration dif-ficulty and 5 cases of arrhythmia. Three cases had long-term complications as the following:one case of catheter-re-lated infection, one case of catheter lost, and one case of incision rupture. Conclusions IVAP is a safe and effec-tive intravenous infusion device. It is crucial to choose individualized implanting access and length by professional surgical team.

Objective To investigate the relationship between eosinophil and in-stent restenosis in acute coronary syndrome patients. Methods One hundred and fifity-one ACS cases werenenrolled in this study. According to the results of coronary angiography (the stented segment lumen loss over 50% was judged to be ISR), patients were divided into the restenosis group and the non-restenosis group. Results Based on the logistic analysis, no significant association was found between eosinophil and ISR, and even after adjustment of related risk factors (P > 0.05). The stratification analysis showed that the high level of eosinophil might increase the risk of ISR in ACS patients with history of hypertension (P = 0.038) and myocardial infarction (P = 0.032). Conclusion Eosinophil may be associated with the risk of ISR in ACS patients with history of hypertension and myocardial infarction. The underlying mechanisms need to be elucidated in further study.

Objective To prepare the chitosan nanoparticles loading 5-[125Ⅰ] Iodo-2'-deoxyuridine (125Ⅰ-UdR-CS-DLN) at 100-200 nm in diameter, and analyze the characteristic of drug sustained-releasing and tumor targeting. Methods Orthogonal experimental design and One-way analysis were applied to optimize the preparation of 125Ⅰ-UdR-CS-DLN using tripolyphosphate cross-linking. Dynamic dialysis was utilized to investigate the in vitro releasing characteristics of the nanoparticles. The tumor targeting effect of the nanoparticles was observed with laser confocal microscopy. Results The optimal conditions for preparing the nanoparticles at particle diameters (70. 39 ± 5.12 ) nm (PDI 0. 16 ± 0. 012 ) were 1 g/L of CS, 2 g/L of TPP, stirring rate 600 r/min, relative molecular mass of CS 3 × 103. The TEM results showed that the exterior of the nanoparticles was spheroid, with a uniform and fine dispersivity. The optimized condition with the initial 125Ⅰ-UdR concentration of 2. 96 MBq/ml at pH5 provided the highest loading capacity (1253. 55 MBq/g) and the highest entrapment rate (42. 35% ). The in vitro releasing curves of 125Ⅰ-UdR-CS-DLN followed Higuchi equation, shown a characteristic of long-acting preparation.Laser confocal microscopy observations approved that the tumor cells uptake of FITC-CS-nanoparticles were significantly more than that of normal cells. Conclusions Chitosan nanoparticles loading 125Ⅰ-UdR at diameters range 127. 81 ± 15. 25 nm (PDI 0. 240 ± 0. 035 ) were successfully prepared with the optimized conditions, and showed a characteristic of sustained-releasing and tumor targeting. The chitosan-based nanotechnology provided a new and efficient approach for the application of 125Ⅰ-UdR in intracellular radiotherapy for tumor.

To evaluate the immunities of biodegradable microsphere as a release delivery system for DNA vaccine against Infectious Bursal Disease Virus, in our study, silk fibroin/chitosan microsphere adjuvant was prepared with a precipitation/coacervation method. Both glutaraldehyde and Na2SO4 solution were used in cross-linking. No immune chicken were intramuscularly inoculated at 14 day-old and boosted 2 weeks later. The results show that glutaraldehyde destroyed the DNA activity of the vaccine whereas Na2SO4 solution did not. Factors of the chitosan concentration 0.5% (pH 5.0), silk fibroin concentration 0.6%, plasmid DNA (500 microg/mL) dissolved in 2% Na2SO4 solution were optimized to produce microsphere, with a loading capacity of 89.14%. The average particle size of SF-CS/pCI-VP2/4/3 microsphere is 1.98 microm, and it can protect the loading DNA vaccine from DNase I digestion. Data from anti IBDV ELISA antibodies in the serum show that immunization activity of the microsphere groups were generally higher than plasmid vaccine group (P < 0.05), and the SF/CS compound microspheres group was better than that of sole CS microsphere group. The developed SF/CS microspheres are a very promising vaccine delivery system.

Aim ToobservetheeffectofSanHuang Decoction (SHD )on glucose and lipid metabolism in insulin resistance(IR)3T3-L1 adipocytes.Methods TheIRmodelof3T3-L1adipocyteswasinducedby high glucose and hyperinsulinism cultivation(also con-taining dexamethasone ).The adipocytes were treated with rosiglitazone(Ros)and different concentrations of SHD(2. 5,5,10,20,40 g·L-1 )for 24 h.The content of glucose disappeared from the culture medium was determined as glucose consumption of the cells. The transport of glucose was observed by 2-deoxidation-[3 H]-glucose uptake method.The efflux of nonesteri-fied fatty acids(NEFA)from adipocytes was observed by the concentration of NEFA in the culture medium. The mRNA expression of glucose transporter-4 (GLUT-4)was measured by real-time polymerase chain reac-tion (real-time PCR).The protein expression of GLUT-4wasdetectedbyWesternblot.Results Compared with the Con group,SHD(5,10,20,40 g·L-1 ) could significantly induce the glucose consumption and transportion(P<0. 01 ),increase the glycerol content in culture supernatant(P<0. 01 ),reduce the NEFA concentration in culture medium and accumulation of intracellular TG(P<0. 01 ).And all of these change showed a concentration-dependent effect when SFD concentrations were from 5 g·L-1 to 20 g·L-1 .At the same time,Ros could also remarkably induce the glucose consumption and transportion(P<0. 01 ),and increase the accumulation of intracellular TG (P <0. 01);but the concentration of NEFA and glycerol in culture medium did not show any difference in the Ros-treatedgroup(P>0.05).Conclusion SHDcanin-crease insulin sensitivity by increasing glucose trans-portation and consumption in the 3T3-L1 adipocytes as well as decreasing the NEFA efflux from the cells.
