Objective To explore the incidence and clinical treatment of related complications caused by implantable venous access port(IVAP) in patients with breast cancer during chemotherapy.Methods The data of 755 patients with breast cancer recieved chemotherapy by which caused some related complications in our hospital from January 2014 to March 2016 were retrospectively analyzed.Results 753 patients IVAPs were implanted succussfully.The total placement time of implantable venous access port was from 110 days to 940 days,with median placement 147.33 days.The related complications of IVAP were catheter malposition(0.79％,6/755),catheter-related thrombosis(27.81％,210/755),catheter fracture(0.13％,1/755),port exposure(0.93％,7/755) and IVAP-related bloodstream infection(0.13％,1/755).The IVAP-related complications and thrombosis rate were significant higher when IVAPs implanted in the left internal jugular veincompared with that in right internal jugular vein(34.88％ vs.25.74％,33.10％ vs.24.68％).Conclusion Application of IVAP in patients with breast cancer during chemotherapy is a safe and effective operation.The most common complication is asymptomatic mural thrombus formation around the catheter,which should be paid attention to.

Objective: To analyze the ability of Chinese characters reading and characteristics of alexia among patients with mild, moderate and severe Alzheimer's Disease(AD). Methods: Chinese characters reading test was performed in 20 normal controls(average MMSE total score is 27.7), 20 mild AD(average MMSE is 21.2),20 moderate AD(average MMSE is 15.2) and 20 severe AD(average MMSE is 6.9). Chinese characters reading test consists of 22 mark-symbol characters, 17 phonetic symbol characters and 17 meaning-symbol characters. Results: No significant difference were found in scores of Chinese characters reading test among normal controls, patients with mild, moderate AD group. Compared with moderate AD, severe AD showed manifest decline for scores of phonetic symbol characters and meaning-symbol characters reading. There wasn't significant different visual paralexia among 4 groups. Surface alexia occurred at early stage of AD and advanced at late stage of AD. These wrong reading were seen frequently in meaning-symbol characters. Deep alexia occurred only at late stage of AD. Compound words phanomenon is the major class of deep alexia. Conclusion: Ability of Chinese characters reading was helpful to estimate premorbid intelligence of the patients with dementia. There are different classes of alexia between Chinese and western languages.

Objective: To investigate applicability for Boston naming test (30 items) (BNT) in Chinese elderly and identify effect for mild cognitive impairment (MCI) and Alzheimer's dementia(AD) using BNT. Methods:100 normal elderly, 38 amnesic MCI, 34 mild AD and 38 moderate AD were evaluated by neuropsychological tests (include BNT, mini mental state examination and auditory verbal memory test, etc). MMSE total score of 4 groups were 28.4?1.5, 26.1?2.6, 20.7?1.7, and 15.6?3.3, respectively. Results: Age, sex, level of education were found to be significant factors affecting overall scores of spontaneous naming in normal elderly group. Spontaneous naming score for participants of elementary, high school and college groups were 22.2?3.3, 25.5?2.5 and 26.3?1.8, respectively. Scoring of male participants higher than that of females. Spontaneous naming score of 4 groups were 24.9?3.0, 20.9?3.6, 18.7?4.0 and 15.7?4.2, respectively. As cut-off ≤22 score of spontaneous naming of BNT, the sensitivities for MCI, mild AD and moderate AD were 61%, 79% and 95% respectively; the specificities were all around 81%. Selective impairment of unfamiliar items occurred MCI and mild AD and hold of familiar item across diagnostic groups. Semantic cue naming and recognition ability by BNT showed there was progressive damage in AD patients, but less than that of spontaneous naming of BNT. Conclusion: The ability of naming is influenced by age, gender and educational level. Patients with MCI or mild AD have impairment in naming.

Objective:The paper aims to provide recommendations for improving the essential medicines’ cen-tralized bidding procurement and quantity-based pricing policy. Methods: Based on the documents and literature on essential medicines’ centralized bidding procurement, we analyzed the factors which have a great impact on implemen-tation of the quantity-based pricing in essential medicines’ centralized procurement using the text research, semi-structured interview questionnaire and on-phone interviews. Results:The quantity-based pricing needs to define a ge-neric name and specific dosage form of drugs in the essential medicines’ centralized procurement. Its implementation was mainly influenced by the following factors:the procurement area accessibility, the pharmaceuticals category, dis-ease and drug alternative procurement methods and cycle, the payment and settlement time, and irregularities in the procurement process. Suggestions:During this implementation, we also need to clearly predict the quantity and pro-curement method, set up a proper policy environment for a quantity-based pricing, cancel the price linkage mecha-nism, strictly put into practice the payment deadline, employ a unique billing method and strengthen the information construction for the provincial centralized procurement platform. Some medicines’ quantity-based pricing should be carried out in the chosen pilots for laying a good foundation for its promotion.

Objective To investigate the value of double contrast-enhanced ultrasonography (DCEUS) in combination with three-dimension (3D) contrast-enhanced ultrasound in diagnosis of benign or malignant gastric ulceration. Methods A total of 47 patients with gastric lesions were enrolled in this study. All have the pathological results, 22 of them were benign ulceration and 25 were malignant. All patients underwent DCEUS and 3D contrast-enhanced ultrasound. On the basis of oral contrast-enhanced ultrasound agents, intravenous contrast-enhanced ultrasound agents were given at the same time. Images and data were recorded. The arrival time (AT), time to peak (TTP), infusion time (IT), baseline intensity (BI), peak intensity (PI) and enhanced intensity (EI) were calculated using the time-intensity curve (TIC). Results All benign ulcerations were imaged as small pits with slight thicken of gastric wall [(8.66±2.87) mm] using DCEUS,while malignant lesions were relatively large irregular-shape, unevenly-bottom pits with significant thicken of gastric wall [(13.98±3.63)~(20.83±3.69) mm]. 3D-DCEUS images were analyzed for gastric mucosal folds, ulceration lesions, as well as local vascularity. All ulceration lesions showed broken of gastric mucosal folds, and malignant lesion showed thickness of gastric wall as“crater”, with rich and irregular vascularity. There were no statistical differences between benign gastric ulcerations and adjacent normal gastric wall (P>0.05). Malignant gastric ulceration were compared with adjacent normal gastric wall tissue, TTP, IT and BI had no statistical differences (P>0.05), while AT, PI, and EI had statistical differences [(9.00±2.02) s vs (10.90±2.75) s, P=0.008], [(35.46±5.77) dB vs (29.73±8.72) dB, P=0.009] and [(30.76±5.76) dB vs (23.45±6.84) dB, P=0.000]. PI and EI in malignant tumors were higher than those in benign ones (P<0.05). Conclusion DCEUS could be a new method in differentiating benign and malignant gastric ulceration, which can get both the anatomy and perfusion information of gastric wall as well as lesions. 3D-DCEUS can improve the quality of the conventional ultrasound image.

Studies on the variation of amylase, lipase and lrotease activity of Whitmania pigra in 0-6 months old using 3, 5-dinitro- salicylic acid colorimetry, right-nitrophenyl palmitate ester (ρ-NPP) colorimetry and folin-phenol method. The results showed that pro- tease activity remained low before 1.5 months old and with the highest activity in 2 months old, but after showing a small peak in 4 months, alkaline protease rapid declined. Amylase was low at born, then gradually increased the activity of the highest in 2.5 months old. Lipase with a strong vitality at birth, then 1 month with minimum and 2 months peaked, but appeared a small peak in 4 months old. In summary, only lipase exhibits strong activity at birth, lipase with the strongest activity in the digestive tract during develop- ment. Protease, lipase and amylase with the strongest activity at 2-3 months old, but were decreased after 4 months old.
