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.

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 observe the therapeutic effect of sertraline combined with brain function treatment instrument for depressive episodes.Methods According to sequence of hospitalization,80 patients with depression without severe physical disease randomly divided into sertraline with brain function treatment group (40 cases,group A) and only take sertraline group (40 cases,group B),and two groups were given Sertraline 100 mg/day for 8 weeks.24 Hamilton Depression Scale (HAMD-24) and 20 Self-rating Depression Scale (SDS-20) were assessed before and after 1,2,4,6,8 weekend treatment.Results The scores of HAMD-24 and SDS-20 were not significant difference between the two groups before treatment(P＞0.05),but there were statistically significant after treatment (P＜0.05).They were significantly decreased after 8 weeks treatment in group A and were decreased slightly in group B with HAMD-24 and SDS-20.Clinical efficiencies of HAMD of the two groups were 87.2 ％,76.3 ％,respectively,and those of SDS were 89.7 ％,78.9 ％,respectively.Clinical efficacy in group A was significantly better than that in group B (P＜0.05).Conclusion Sertraline with brain function treatment instrument can shorten the onset time and improve its effect.

Objective To evaluate CT-guided pereutaneous biopsy and fine needle aspiration in diagnosing malignant musculoskeletal tumors. Methods CT-guided percutaneous biopsy and fine needle aspiration was performed in 106 cases with suspected musculoskeletal tumor. The pathological results obtained from biopsy specimens were compared with clinical final pathological diagnoses. Results All 106 cases were finally diagnosed as suffering from malignant musculoskeletal tumors, which were proved by operation and incisional biopsy. Of 106 cases receiving CT-guided percutaneous biopsy and needle aspiration, the pathologic diagnosis obtained from this procedure was consistent with the clinical final pathological diagnosis in 89 and was "negative" in 17, with an accuracy rate of 84.0%. Conclusion CT-guided percutaneous biopsy and fine needle aspiration is a safe, simple and effective technique for the diagnosis of malignant musculoskeletal tumors, Incisional biopsy may be necessary when this procedure gives "negative" result.

Objective To assess the prevalance and distribution of pain in Parkinson' s disease (PD) patients, and to describe the relationship between pain and development of disease and its impact on the quality of life. Methods 113 PD patients were assessed with Visual Analog Scale (VAS), Brief Pain Inventory (BPI), Unified Parkinson' s Disease Rating Scale (UPDRS), Hoehn-Yahr Scale (H-Y), Hamilton Anxiety and Depression Scale (HRSD, HAMA) and Pittsburgh Sleep Quality Index (PSQI). Patients were divided into no pain group, PD-pain group and non-PD-pain group. PD-pain group was divided into PD-pain direct group and PD-pain indirect group. And statistical analysis was performed for each group. Results The incidence of PD-pain was 42. 5% (48/113). And compared with no pain group, PD-pain group had earlier age at onset of disease, longer duration, higher HAMA, HRSD, UPDRS and H-Y score, higher daily L-dopa dose, with statistical significance. Compared with non-PD pain group, the differences in the onset of age (57.4±9.6 vs 65.9±8.7, t= -2.596, P =0.012), HRSD(12. 9±7.9 vs 8.7±3.7, t =2.605, P=0.014) and VAS (61.6±25.9 vs 38.0 ± 30. 1, U = -2.290, P =0.022) were also statistically significant. BPI was different between PD-pain direct group and PD-pain indirect group except normal work and relations with other people. Conclusion Pain is frequent in Parkinsonian population. Most pain was chronic and related to PD (PD-pain). These patients always have earlier onset age and poorer quality of life.

Objective To prospectively assess the therapeutic procedure and outcome of MR-guided percutaneous sclerotherapy in patients with venous vascular malformations of the extremities. Methods Fifty-seven percutaneous sclerotherapy treatments were performed under MR guidance in 28 patients with venous vascular malformation. Assessment was conducted to analyze (1) individual success of therapy, (2) improvement of clinical symptoms, ( 3 ) occurrence of complications, (4) volume changes at follow-up examinations, (5) contrast-to -noise ration (CNR) changes. Paired-t test was used to compare the volume and CNR of pre- and postintervention. Results All MR-guided percutaneous sclerotherapy were performed successfully and without serious complications. Individual predominant symptoms were improved, especially about the pain and functional impairment. The mean lesion volumes of pre- and post-intervention were (56. 8 ± 11.7 ) cm3 and ( 27.0 ± 7.2 ) cm3 respectively, which showed significant difference ( t = 8. 90, P < 0. 01 ). The percentage of volume shrinkage ranged from 28. 5% to 74. 4% [ mean ( 54. 4 ± 5. 3 ) % ]. The CNR of the pre and post-interventional images were 21.9 ± 2. 0 and 8.4 ± 0. 9 respectively. There was significant difference(t = 21.76, P < 0.01 ) between them, and the percentages of CNR decrease were 40.0% to 78. 0% [ the mean(61.0 ± 3.6)%]. Conclusion MR-guided sclerotherapy of venous vascular malformations of the extremities is a safe and efficient technique.
