5.18F-FDG PET/CT in Diagnosis of Small Intestinal Malignant Neoplasm
Chinese Journal of Medical Imaging 2015;(1):19-22
Purpose To analyze the 18F-FDG PET/CT features of small intestinal malignant neoplasm, and to discuss the diagnosis value. Materials and Methods Forty-seven patients who were highly suspected with small intestinal tumors underwent 18F-FDG PET/CT whole body scan were retrospectively analyzed, the results of PET/CT examinations and the findings of biopsy and surgical pathology were compared. The maximum of intestinal wall thickness (IWTmax) and maximum of standardized uptake value (SUVmax) were calculated to analyze the relationship of them under different pathological conditions. Results Six out of the 47 small intestinal tumors were benign, the other 41 were malignant tumors among which 19 were malignant lymphoma and 17 were adenocarcinoma. The sensitivity, specificity, accuracy rate, positive predictive value and negative predictive value of 18F-FDG PET/CT in the diagnosis of small intestinal malignant neoplasm were 92.7%, 83.3%, 91.5%, 97.4% and 62.5%, respectively. Compared with those of benign tumors, the SUVmax and IWTmax of malignant intestinal tumors were significantly higher (t=5.596 and 2.376, P<0.05). The SUVmax in small bowel adenocarcinoma was significantly lower than that in malignant lymphoma (t=2.419, P<0.05);the IWTmax. between the two kinds of tumors showed no difference (t=0.369, P>0.05). The SUVmax and IWTmax of small intestinal malignant lymphoma had no correlation (r=0.293, P>0.05), whilst there was significant correlation between the IWTmax and SUVmax in small intestinal adenocarcinoma (r=0.542, P<0.05). Conclusion The SUVmax and IWTmax of malignant intestinal tumors are higher than those of benign intestinal tumors; 18F-FDG PET/CT imaging is rather reliable in differentiating small intestinal malignant tumors from benign ones. Intestinal malignant lymphoma shows a higher uptake of 18F-FDG than intestinal adencarcinoma, but the intestinal wall thickness of the two kinds shows no difference.

China Pharmacy 2016;27(18):2494-2496
OBJECTIVE:To observe the efficacy of capecitabine combined with cisplatin in the treatment of advanced gastric cancer and its effect on invasion and metastasis of gastric cancer. METHODS:94 patients with advanced gastric cancer were ran-domly divided into control group(47 cases)and observation group(47 cases). Control group received 65-75 mg/m2 Docetaxel injec-tion,d1,continuous intravenous infusion of 2 h+15-20 mg/m2 Cisplatin for injection,d1-5,continuous intravenous infusion of 2 h in the dark. Observation group received 1 000 mg/m2 Capecitabine tablet,orally,twice a day+Cisplatin for injection(the same us-age and dosage with control group). 3-week was regarded as a treatment course,and it lasted 3 courses. Clinical efficacy,matrix metalloproteinase-2(MMP-2)and MMP-9 levels were observed,6 and 12 months survival rate and incidence of adverse reactions were followed-up. RESULTS:There was no significant difference in the total effective rate in 2 groups(P>0.05). Grade 1-2 liver dysfunction,thrombocytopenia,and the incidence of nausea and vomiting in observation group were significantly lower than con-trol group,6 and 12 months survival rates were significantly higher than control group,the differences were statistically significant (P<0.05). Before treatment,There was no significant difference in MMP-2 and MMP-9 levels in 2 groups(P>0.05). After treat-ment,MMP-2 and MMP-9 levels in 2 groups were significantly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). CONCLUSIONS:The efficacy of capecitabine combined with cispla-tin is similar to docetaxel combined with cisplatin in the treatment of advanced gastric cancer,but docetaxel combined with cisplat-in is superior in terms of reducing MMP-2 and MMP-9 and safety.

Journal of China Pharmaceutical University 2009;40(4):332-336
Aim: To study the hydrofluoroalkane-driven(HFA-134a) salbutamol sulfate (SS) MDI formulation compositions and the respiratory tract absorption in rats. Methods: Solubility determination and orthogonal design were used to aid the screening of non-CFC SS MDI formulations. Rats were exposed to SS MDI via intubation inhalation. Fluorescent HPLC detection was developed to determine plasma SS concentration in rats given the selected SS MDI formulations. Analysis of the plasma drug level-time profiles was performed by the statistical moment approach. Results: Stable and homogeneous non-CFC SS MDI formulations were obtained. The developed HPLC method was validated and used to assay SS levels in the rats after inhalation of the MDI. AUC ratios of the SS/HFA-134a-driven MDI formulation to the reference SS MDI and CFC SS MDI formulation were 109. 86% and 135. 54%, respectively. Conclusion: It is proven that the absorption of the HFA-134a SS MDI formulation in rats is equivalent to the simulant formulation commercially available oversea and better than CFC formulation.
8.Quick termination and implications of medical service price reform policy in Chongqing city:A case study of health policy with perspective of policy actors
Chinese Journal of Health Policy 2017;10(1):2-7
Local policy innovation is a distinct feature in the arena of public administration in China. Previous researches concerned with local policy innovation experience and policy introduction, but they pay little attention to the failure of policy innovations and their termination. This paper uses the theory and concept of public policy process to analyze the reasons for the quick termination process and its mechanism taking healthcare policy as a case study in Chongqing city. It concludes that relative policy strategy is closed in decision-making. The strategy of some special policy target groups as well as the mutual agitation between public and media agenda are the main reasons for the rap-id end of policy innovation. This study is helpful to understand the factors and logic mechanism of the quick termina-tion of local policy innovation as a special type of public policy change which is termed as short-lived and make more scientific healthcare policy decision making and reform in China.
9.Direct effects of platelet-activating factor on pulmonary artery endothelial cells
Chinese Journal of Pathophysiology 1989;0(05):-
Platelet-activating factor(PAF) at different concentrations were added to in vitro cultured bovine=pulmonary artery endothelial cells(BPAEC) when lactate dehydrogenase(LDH) release rate, angiotensin converting enzyme(ACE) activity and malondialdehyde (MDA) content were determined. The influences of specific PAF receptor antagonist on PAF effects and the stimulating effect of PAF on leukocyte-endothelial cell adhesion were also observed. The results showed that when PAF were added to BPAECs, there were no significant change in LDH release rate, ACE activities were only slightly increased. No obvious changes in cellbound MDA, but supernatant MDA content was increased in cells treated with high concentration of PAF (10~(-6)). The PAF receptor antagonist, SRI 63-441 made the cell-bound MDA content higher than that of PAF treated cells, whereas the supernatant MDA became lower. PAF may promote endothelial-leukocyte adhesion either through its effects on endothelial cells or on leukocytes, suggesting that PAF has no obvious damaging effect on endothelial cells but may activate endothelial cells thus promoting endothelialleukocyte adhesion.
10.Primary study of diffusion-weighted imaging in evaluation of fetal renal development
Journal of Practical Radiology 2016;32(4):580-583
Objective To investigate the characteristics of apparent diffusion coefficient (ADC)values in the normal fetal kidney and to explore the normal data reference of fetal kidney by using diffusion-weighted imaging (DWI).Methods 71 normal kidneys of fetuses confirmed by ultrasound and MR were examined with DWI with four b values of 100 s/mm2 ,200 s/mm2 ,500 s/mm2 and 700 s/mm2 ADC values of the symmetrical ROIs were compared between left and right kidney for each b value.While ADC values between different group in ipsilateral kidney were compared between different b values.And the relationship between ADC values and gestational age was also evaluated.Results When b = 100 s/mm2 ,there was a statistically significant difference between the ADC value of left and right kidney,and the remaining group showed no statistically significant differences between the ADC values of left and right kidney.Comparisons among different b values of ipsilateral kidney showed statistically significant differences among the groups with different b values except the comparison between b=100 s/mm2 and b=700 s/mm2 groups of the right kidney with the increase of gestational weeks,the ADC values of bilateral kidneys were declining,and there was a reflection of this trend in different b values. Conclusion It is feasible for using DWI to evaluate the fetal kidney development.With a selected different b value,ADC value is a specific quantitative parameter that could help evaluating normal fetal kidney development.
