Objective To evaluate the influence of lesion size and depth on the diagnostic accuracy and the rate of pneumothorax in patients undergone CT-guided transthoracic aspiration biopsy for pulmonary lesions.Methods CT-guided percutaneous transthoracic biopsy was performed in 398 patients that had surgical resection or clinical follow-up.According to lesion size,lesions were divided into≤2 cm,2～4 cm and ≥4 cm.Lesion depth was measured from the pleura surface to the edge of the lesion.This depth was classified in three categories:≤1 cm,1～3 cm and ≥3 cm.Comparison of the diagnostic accuracy and the frequency of pneumothorax in different size and depth of lesion was performed.Results(1)The overall diagnostic accuracy of CT-guided percutaneous needle aspiration biopsy was 83.2%(331/398).Pneumothorax occurred in 58(14.6%)of 398 biopsy;(2)The diagnostic accurate rate in different size of lesion was 73.3%(44/60),81.5%(176/216)and 91.0%(111/122)respectively,?2=9.91,P0.05.The occurred rate of pneumothorax in different depth lesion was 2.8%(4/141),14.8%(21/142)and 28.7%(33/115),?2=34.03,P

Objective To investigate the factors influencing the diagnostic accuracy in CT-guided percutaneous transthoracic aspiration biopsy of lung lesions. Methods CT-guided percutaneous transthoracic biopsy was performed in 435 patients with surgical pathologic confirmation or clinical follow-up.Univariant statistical analysis and multivariant stepwise Logistic regression analysis were used to study the influence of lesion-related factors(benignancy or malignancy,size,location,depth,presence of cavity),procedure factors(laser-guidence,position of patient) and patient-related factors(sex,age,presence of emphysema);with the accuracy of the diagnosis. Results ① 289 lesions were diagnosed as malignant ones and 146 as benign ones.The accuracy of CT-guided biopsy was(83.4%)(363/435).Univariant analysis showed that the diagnostic accuracies for malignant and benign lesions were(88.9%)(257/289) and(72.6%)(106/146),respectively(?~2=(18.71),P=(0.00002)).Laser-group was superior to non-laser group((88.4%) versus(80.9%),respectively,?~2=(4.00),P=(0.0456)).Mean diameters of lesions in correct diagnostic group and non-correct diagnostic group were(3.78)?(1.64) cm and(3.02)?(1.26) cm,respectively((F=)(13.79),P=(0.0002)).②Multivariant stepwise Logistic regression analysis showed that among the various factors influencing the final benign or malignant diagnoses(Wald ?~2=(14.01),P=(0.0002)) and using laser-guidence(Wald ?~2=(3.92),P=(0.0477)) were significantly associated with the diagnostic accuracy. Conclusions Final correct diagnoses(benign,malignant) are closely related to the application of laser-guidence for determining the diagnostic accuracy in CT-guided transcutaneous thoracic needle aspiration biopsy.

To investigate the effects of Tianqi Pingchan (TQPC) Granule, a compound traditional Chinese herbal medicine with antitremor activity, on levodopa-induced dyskinesia and the expression of G protein-coupled receptor kinase 6 (GRK6) in rats with Parkinson disease (PD).

Marine traditional Chinese medicine (MTCM) is an important part of Chinese medicine (CM),there are some differences in understanding of the current literature and the extension of the connotation of marine medicine,which leads to the definition dispute of MTCM,hindering clinical application and further development of MTCM.In this study,we explored the concept of MTCM in literature,discussed the attributes of ocean marine CM,summed up the differences between the land CM and MTCM over variety characteristics,effect of drug composition characteristics and biological activity characteristics,and discussed the connotation and extension of MTCM from three aspects of theoretical basis and the effect and source of the drug,leading to the formation of the narrow and broad concept of MTCM.The five kinds of disputes in the definition of MTCM were discriminated according to the concept and connotation,which provided a theoretical basis for the definition and the research of MTCM.Moreover,we also defined the English translation and its abbreviation as Marine Traditional Chinese Medicine (MTCM).

ObjectiveTo investigate the effect of MK-801 on levodopa-induced dyskinesia (LID)in Parkinson' s disease (PD). MethodsRat models ( n = 25) of Parkinsonism related motor complications were established and were randomly divided into levodopa-induced dyskinesia (LID) group (n = 10), MK801 treatment group (n = 10) and PD group (n =5). Another 5 rats were served as control group. The behaviors of LID rats treated with MK-801 were observed. Immunohistochemistry and Western blot analysis were used to determine the expression of β-arrestin1 in the striate of rats.Results After MK-801 treatment, abnormalinvoluntarymovementscores and peakturning weredecreasedin LIDrats.Immunohistochemistry showed that β-arrestin1-positive cells of the lesioned side ((2. 95 ± 0. 44) × 104) in LID rats were decreased compared to the contralateral side ( ( 3.78 ± 0. 37 ) × 104, t = 5. 415, P ＜ 0. 05 ).Western blot showed that the levels of β-arrestinl in PD group ( presented as lesioned side/contralateral side) were ( 81.02％ ± 2. 23％ ). The levels of β-arrestin1 (64. 88％ ± 3. 10％ ) were deceased in LID rats compared to PD rats ( t = 9.47, P ＜ 0. 01 ). However, the levels of β-arrestin1 ( 89. 26％ ± 1.90％ )were increased in MK-801-treated rats (t = 14. 82, P ＜0. 01). ConclusionsMK-801 reduces LID in PD rats. The beneficial effect of MK-801 may be mediated through the increased expression of β-arrestinl which in turninhibits the overactivation of glutamate receptors.

Objective To investigate the relationship between G protein-coupled receptor kinase 6 (GRK6) and N-methyl-D-aspartate (NMDA) receptor in the mechanism study underlying motor complications in Parkinson's disease (PD).Methods The rat models (n= 25) of Parkinsonism related motor complications were established and were randomly divided into levodopa-induced dyskinesia (LID) group (n= 10,intraperitoneal injection of levodopa for 23 d),MK-801 treatment group (n= 10,intraperitoneal injection of MK-801 at day23 after intraperitoneal injection with levodopa for 22 days) and PD group (n= 5,intraperitoneal injection of vitamin C).Another 5 rats were served as controls (sham-operation group).The behavior changes of rats in MK-801 treatment group were observed,and the expression of GRK6 in the striate of rats was detected by immunohistochemistry and Western blot.Results After the chronic treatment with levodopa methyl ester,PD rats displayed abnormal involuntary movements,which was similar to levodopainduced dyskinesia in PD patients.Immunohistochemistry showed that GRK6-positive cells of lesion side were decreased in LID rats as compared with PD rats [(3.23±0.41 ) × 103 vs.(4.81 ± 1.31 ) ×103,P＜0.01].Rats in MK-801 treatment group displayed the decreased AIM scores and increased peak rotation,and the increased GRK6-positive cells of lesion side as compared with LID rats (P＜0.05).Western blot showed that the levels of GRK6 was 83.7% ±2.1% in PD group (presented as lesion side/unlesion side),76.8% ± 2.2% in LID group and 91.1% ± 2.7% in MK-801 treatment group (intergroups comparison:all P＜0.05).These results were in accordance with the results of immunohistochemistry.Conclusions Antagonist of NMDA receptor can be used to reduce the motor complications in rats.It may be due to increased GRK6 which inhibits the overactivation of glutamic acid receptors.
