Chinese Journal of Ultrasonography 2003;0(07):-
Objective To investigate the types of ultrasonographic appearance of post-hepatectomy in operative position. Methods The data about operative manner,operative position, type of plugger in residul cavitity of 176 cases who underwent hepatic operation,were collected. Their ultrasonographic findings of post-operative liver in operative position in different phrases after operation were analyzed retrospectively. Results The main appearance was: ① Absence of partial hepatic lobe or hepatic segment; ② anechoic area with thin wall or mixed mass in operative position; ③ conformation of irregular high-echo conglomeration in operative position, irregular wall thickeness and inhomogenous internal echoes appeared in anechoic area and mixed mass in operative position, color Doppler twinking artifact appeared around some plugger and residual cavity which made by curettage and aspiration technique with time passing by. Conclusions Ultrasonographic appearance of post-hepatectomy in operative position varies with different operative manner, operative position, resected area, and Absence or existence of plugger in residual cavity, different type of plugger in residual cavity.

Objective To evaluate the value of high frequency color Doppler ultrasound in diagnosis of malignant tumor in the parotid gland.Methods High frequency ultrasound was used to observe shape and internal echo texture of tumor,color Doppler flow imaging(CDFI) was added to observe blood flow signal,peak systolic velocity(PSV) and resistance index(RI) were measured by pulsed wave Doppler, and lymphonodus around parotid gland were examined.Results The features of ultrasonography included round,lobulated and irregular shape.Three types of boundary were clear but not smooth,unclear,irregular and invasive.Internal echo texture included low and irregualr echo,cystic echo,spot like and intensive echo,honey comb like echo.CDFI showed spet like,stick like blood flow signal.PSV and RI were 4.6 17.5 cm/s,and 0.69 1.14 .Eight cases were misdiagnosed for benign tumor,the correspondent rate was 87.1% .Conclusions The high frequency ultrasonogram of malignant tumor in the parotid gland were similar and specific,adding the CDFI,PSV,RI and lymphonodus examination around the parotid gland may help to improve the diagnostic accuracy.

BACKGROUND:Internal fixation is commonly used in an early stage of intertrochanteric fractures of the aged worldwide, and can apparently reduce complications and fatality rate. The commonly used internal fixators contain proximal femoral nail anti-rotation and dynamic hip screw, whose comparison is current research hotspot.
OBJECTIVE: To evaluate the hip function and stability after internal fixation with proximal femoral nail anti-rotation and dynamic hip screw in repair of intertrochanteric fractures of the aged.
METHODS:A total of 64 aged patients with intertrochanteric fractures were enroled in this study, and assigned to dynamic hip screw group (n=30) and proximal femoral nail anti-rotation group (n=34). The fracture reduction and healing were evaluated using anterioposterior and lateral X-ray films. Operation time, intraoperative blood loss, complication rate, healing time and postoperative hip function were compared and analyzed between the two groups, and then assessed in accordance with Sander’s scoring system.
RESULTS AND CONCLUSION:Compared with dynamic hip screw group, operation time, intraoperative blood loss, healing time and complication rate after treating unstable intertrochanteric fracture (Tronzo-Evans III, IV and V types) showed significant advantages in the proximal femoral nail anti-rotation group (P < 0.05). Hip function restored better, and the complication rate of stable intertrochanteric fracture (Tronzo-Evans I and II types) was lower after treatment in both groups (P > 0.05). These data show that the effects of proximal femoral nail anti-rotation were better than that of dynamic hip screw for treatment of intertrochanteric fractures, and hip function recovered better. Moreover, proximal femoral nail anti-rotation had biomechanical stability, especialy for unstable fracture.

Objective To research the clinical significance of leukocyte-platelet aggregates(PLA)in patients with acute cerebral infarction.Methods Sixty-five patients with acute cerebral infarction and 24 controls.The levels of PLA,platelet-neutrophil aggregates(PNA),platelet-lymphocyte aggregates(PLyA)and platelet-monocyte aggregate(PMA)were analyzed by two-color flow cytometry,soluble P-selectin(sP-sel)was detected by ELISA,serum C-reaction protein(CRP)was detected by nephelometry and platelet aggregation rate(PAR)was measured by blood agglutination.Results There were no differences in the percentages of PLA,PNA and PLyA between patients(4.12?1.17%,4.09?1.27%,4.28?1.09%)and controls(4.10?0.99%,3.98?1.12%,4.01?1.98%).However,in the patients before treatment,the percentage of PMA(11.54?1.88%)was significantly increased compared with that after treatment(8.40?2.74%,P

Objective To explore the enhancement patterns of pulmonary carcinomas by contrast-enhanced ultrasound(CEUS).Methods Thirty-eight patients with pulmonary carcinomas proven by pathology[28 with peripheral pulmonary carcinomas and 10 central pulmonary carcinoma with obstructive atelectasis(OA)]were examined by baseline ultrasound and contrast-enhanced ultrasound,then the arrival time(AT),time to peak(TTP)were analyzed with time-intensity curve analysis software and the dynamic enhancement pattern of each lesion was assessed.Results Twenty-four peripheral pulmonary carcinomas demonstrated delayed AT about 6-16 s after application of contrast medium,three lesions demonstrated early AT about 4-5 s and one lesion demonstrated absence of contrast enhancement.The lesions exhibited hyper-,hypo- and non-enhancement were 14,13 and 1,respectively.Seventeen lesions were heterogenous enhanced with non-enhanced necrosis areas and enhanced septa,while ten lesions homogeneous enhanced and one lesion no enhanced.Ten central pulmonary carcinoma with OA demonstrated a characteristic pattern:OA appeared a short AT(mean AT 4.8 s)until enhancement and strong contrast enhancement,while the central tumors appeared a delayed AT(mean AT 10.5 s)and faint enhancement.Conclusions CEUS can be useful in differentiation between solid and cystic pulmonary lesions,and detection of the latent lesions underlying the atelectasis.
