BACKGROUND: Primary progressive aphasia(PPA) is a degenerative disease of nervous system, which is very rare in clinics. Only 3 cases have been reported in our country. There is very little clinical information regarding the characteristics of PPA in linguistics and imageology.OBJECTIVE: To report the language disorder and the characteristics of imageology of one PPA patient for the clarification of the clinical features of PPA.DESIGN: A case analysis.SETTING: Department of Neurology, Beijing Tiantan Hospital; Faculty of Psychology, Beijing Normal University.PATICIPANT: Male, 56 years old, senior high school graduate, businessman before the onset of the disease. The case visited the department of Neurology,Tiantan Hospital, Beijing due to the complaint of three years of progressive decreasing in language skills, which was then diagnosed with PPA.METH ODS: Spoken language fluency evaluation in Chinese Aphasia Examination Set of the First Affiliated Hospital of Beijing Medical University was used to evaluate this patient, the type of Aphasia was judged by Western Aphasia Examination Set, and the severity gradation was classified by the Boston Diagnostic Aphasia Examination(BDAE) . Memory, intelligence screening and imageology examination were performed as well.MAIN OUTCOME MEASURES: The fluency of spoken language, the type of aphasia, and the severity of aphasia of the patient were judged, and whether the patient suffered from memory and intelligence disorder were observed as well as the features of imageology.RESULTS: The patient had fluent spoken language, which was evaluated as sensory aphasia(SA) with the aphasia severity of level 4, and had no memory or intelligence disorder. MRI showed atrophy in left frontal lobe and temporal lobe, which was more significant in left side. MRI also showed that left temporal and frontal lobes had low metabolism and low perfusion.CONCLUSION: PPA is a disease with language disorder as its dominant clinical manifestation, which no other cognitive disorder at its initial stage,and with its main pathological changes in left temporal and frontal lobes.

Objective To observe the effect of multiple interventions on secondary epilepsy patients.Methods 114 secondary epilepsy patients were randomly divided into the intervention group and control group with 57 cases in each group.The cases in the intervention group received multiple interventions including heath education,psychological treatment,safety nursing,overdose administration,early rehabilitation,discharge guide and so on besides usual nursing.While,the cases in the control group received usual nursing.The follow-up was performed for 6 months and the therapeutic efficacy of two groups was compared.Results After multiple interventions,the seizure frequency and trauma incidence rate decreased,compliance and quality of life increased in patients of the intervention group,and there was a significant difference compared with the control group(P<0.05).Conclusion Multiple interventions can decrease seizure frequency and increase compliance of treatment and quality of life of secondary epilepsy patients.

A novel drug delivery system combining oral fast dissolving film with sodium deoxycholate/phospholipid mixed micelles was prepared to increase the absorption of cucurbitacin B that is a poor aqueous solubility substance. Encapsulation efficiency, particle size, zeta potential, polydispersity coefficient, investigated the morphology, disintegration time of oral fast dissolving film and the pharmacodynamic properties of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles before and after solidified in mice were evaluated and compared. The oral fast dissolving film prepared in this study showed a homogeneous pale yellow and could completely disintegrated in the 30 s. It could meet the requirements of rapidly disintegrating fully. The encapsulation efficiency, particle size, zeta potential, polydispersity coefficient of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles loaded in oral fast dissolving film were (43.36 +/- 2.12)%, (108.82 +/- 5.2) nm, (-34.18 +/- 1.07) mV, 0.088 +/- 0.012, respectively. The encapsulation efficiency, particle size, zeta potential, polydispersity coefficient of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles in solution were (41.26 +/- 2.22)%, (181.82 +/- 4.48) nm, (-30.67 +/- 0.81) mV, 0.092 +/- 0.012, respectively. The difference of pharmacodynamics among film of cucurbitacin B-loaded micelles, cucurbitacin B-loaded micelles and free cucurbitacin B in vivo was compared. Solubility of cucurbitacin B loaded in sodium deoxycholate/phospholipid-mixed micelles has also been greatly improved. The tumor inhibition rate of cucurbitacin B loaded in sodium deoxycholate/phospholipid-mixed micelles was significantly improved and did not change significantly before and after solidified. These showed that the sodium deoxycholate/phospholipid-mixed micelles could enhance the antitumor activities of cucurbitacin B and the stability of cucurbitacin B sodium deoxycholate/phospholipid-mixed micelles was improved significantly after solidified by oral fast dissolving film technology without pharmacodynamic properties changed significantly.

Objective To detect levels of IL - 4 and INF - ? in induced sputum dynamically in children with mycnplasma pneamo-niae pneumonia( MPP), and to analyze the function of Th1 /Th2 cell factor immune response in the genesis and development of MPP, so as to evaluate the clinical value of induced sputum method in MPP research. Methods There were 38 cases who were diagnoses as MPP using 3% high osmotic pressure of saline water to ultrasonic atomizing inhalation for inducing sputum. ELISA was used to detect IL-4 and INF-?. Results The content of IL-4 in acute stage was higher than that in convalescence stage in induced sputum of MPP children. Severe stage was higher than mild stage. However, the comparison between acute and convalescence stage didn't have statistics difference in the content of INF-?, neither did the comparison between severe and mild stage. IL- 4/INF- ? in acute stage was higher than that in convalescence stage. Severe stage was higher than mild stage. In convalescence stage, the comparison of INF - ?, IL - 4, IL - 4/INF - ? between the severe and the mild didn' t have statistic significance. Conclusions IL-4 and INF - ? have participated in the monogenesis of MPP. The disequilibria of Th1 /Fh2 is existed in MPP and Th2 reaction predominates. So induced sputum analysis can be a better way to judge the light or heavy press degree of MPP practically, conveniently and sensitively.

A in vitro platelet aggregation bioassay was developed for the quality control of XST capsules. The in vitro anti-platelet aggregation effect in rats was observed to detect the bioactivity of XST capsules. Panax notoginseng saponins and Xuesaitong lyophilizedpowder for injection were taken as standard control substances to determine the potency. According to the results, XST capsules showeda significant inhibitory effect on thrombin-induced platelet aggregation in a dose-dependent manner. The in vitro anti-platelet activity oflyophilized powder for injection was stabler than that of Panax notoginseng saponins, and so suitable to serve as a standard control substance. The biological potency of XST capsules compared with standard control substance was detected by using parallel line assay. According to the results, the established bioassay method had a good repeatability (RSD 2.92%). The sample test results could pass thereliability test(linear deviation P > 0.05, parallel deviation P > 0.05). This bioassay method could be used as one of the complementary quality control methods for XST capsules.

OBJECTIVETo identify the anatomical variability of the left spermatic vein (LSV) and determine its effect on the induction of experimental left varicocele (ELV) in adolescent rats.

METHODSWe equally randomized 30 adolescent male SD rats to groups A (LSV collaterals fully ligated and the left renal vein constricted), B (only the left renal vein constricted), and C (sham operation), observed the courses of the LSVs and measured their diameters. At 30 days after operation, we analyzed the changes in the left kidneys and the diameters of the LSVs.

RESULTSIrregular collaterals were observed in 90% of the LSVs and no abnormal changes were found in the left kidneys after surgery. The postoperative LSV diameter was remarkably increased in group A as compared with the baseline ([1.47 +/- 0.15 ] vs [0.16 +/- 0.08] mm, P < 0.01), but showed no significant difference in group B ([0.31 +/- 0.49] vs [0.15 +/- 0.07] mm, P > 0.05) and C ([0.17 +/- 0.07] vs [0.16 +/- 0.06] mm, P > 0.05), and it was significantly longer in A than in B (P < 0.01). The success rate of ELV induction was 100% in group A and 10% in group B, but no varicocele was observed in group C.

CONCLUSIONCorrect identification of the anatomical course of the LSV and ligation of its irregular collaterals are essential for the establishment of a stable and consistent ELV model.

OBJECTIVETo analyze the relationship between Chinese medical constitutions and chemotherapy-induced leucopenia (CIL) of primary breast cancer patients.

METHODSTotally 306 breast cancer patients undergoing adjunctive chemotherapy for the 1st time, and effective 291 breast cancer patients were recruited in this study.Nine Basic Constitutional Scale was used before first chemotherapy. Chinese medical constitutions were classified and quantitatively scored. The highest grading for any item of adverse reactions in each case during the whole chemotherapy course was recorded after chemotherapy. Data were statistically analyzed using SPSS16.0.

RESULTSThere was no significant difference in CIL between different chemotherapy regimens and various Chinese medical constitutions of breast cancer patients (P > 0.05). Yang deficiency constitution is one risk factor for CIL. The higher the score of yang deficiency constitution, the more severe the CIL.

CONCLUSIONSYang deficiency constitution was correlated with the degree of CIL. The higher the score of yang deficiency constitution, the greater the risk of III-IV grade CIL in breast cancer patients.
