Eosinophil cationic protein, a sensitive marker of activated eosinophils, plays an important role in eosinophila inflammation, such as asthma, allergy disease and so on. To get acknowledges of ECP of secretion and use in nasal general chronic disease(NP, CS and AR),we review many articles and summary the present situation of this topic of its properties and uses. We find a critical relationship between ECP and nasal general chronic disease. Moreover, the measurement concentration of ECP in nasal fluid can help evaluate degree, turnover and prognosis of these diseases.

Objective To investigate the role of Catbindin-D28k in the kidney on calcium metabolism.Methods VDR/CaBP-D28k double knockout(KO)mice was made.Body weight,diet intake and serum,urinary parameters and length,density of the long bones,histological staining of the tibia of WT,CaBP-D28(-/-),VDR(-/-)and VDR(-/-)/CaBP-D28k(-/-)mice were determined on regular and high Ca-Lac diet.Results On a regular diet,the double KO mice were growth-retarded more and smaller than VDR KO mice.Compared with VDR KO mice,the double KO mice had higher urinary calcium excretion and rachitic skeletal phenotype,which were manifested with higher serum parathyroid hormone levels,lower bone mineral density,and more distorted growth plate with mole osteoid formation in the trabecular region.On high calcium and high lactose diet,blood-ionized calcium levels were normal in both VDR KO and the double KO mice.However,in contrast to VDR KO mice,the skeletal abnormalities were not completely corrected in the double KO mice.Conclusion These results directly demonstrate that CaBP-D28k plays a critical role in maintaining calcium homeostasis and skeletal mineralization and suggest that its caleemic role can be mostly compensated by CaBP-D9k.

Objective To evaluate the effect of combination transfer pump and single blood pump to 32 cases of renal failure patient who need blood purification therapy.Methods The combination transfer pump and single blood pump were used.According to the clinical requirement,the parameters of transfer pump were set such as therapy time,replacement liquid flow rate,dialysate flow rate,temperature of warmer and filtrate flow rate,etc.Results 32 patients with varying degrees of illness have been alleviated.Patients' acute left heart failure,water and electrolyte turbulences,acid intoxication and azotemia caused by liquid retention were corrected,which ensured a role for further treatment.Conclusion It is the functions of adjustable time and transfusion volume that are used in the combination transfer pump,the task of which is accomplished by several transfer pumps together.This method is easy to implement and can meet the clinical requirement largely without special CBP instrument.

Glomus tumor arises from the subcutaneous glomus body, which is an arteriovenous anastomosis involved in the regulation of cutaneous blood circulation and are widely distributed in the body, especially the hand. Twelve patients (male 3, female 9) with glomus tumors of the hand, who were operated from Jan. 1986 to Dec. 1994 were selected. The lesions were distributed in the distal phalanges of the thumb (6 cases), the index (3 cases), the ring finger (2 cases) and the little finger (1 case). All patients had the classic triad of symtoms: pain, tenderness and temperature sensitivity. Palpable mass (4 cases) and bluish purple discoloration in the skin (6 cases) were also presented. They had no trauma history and on the roentgenography, bone change detected in 2 cases. A simple excision with partial nail extraction was done in all cases. The symtoms were disappeared in all cases and no recurrence was found. For a complete cure, meticulous complete excision is the only recommended treatment.

Objective To explore the clinical value of high-frequency color Doppler ultrasound in the diagnosis of isolated calf muscle vein thrombosis (ICMVT). Methods Sonographic features of 175 patients with isolated calf muscular venous thrombosis were analyzed retrospectively and outcome of anticoagulant therapy in 1, 3, and 6 months was followed up. Diagnosis was established with high-frequency color Doppler ultrasound examination. Results One hundred and seventy-ifve patients presenting with 190 calf muscle vein thrombosis were included. One hundred and iffty-eight cases with 173 calf muscle vein thrombosis were diagnosed by high-frequency color Doppler ultrasound, 7 cases of misdiagnosis, missed diagnosis in 10 cases. The accuracy rate was 91.1%(173/190). Seven cases were misdiagnosed with 1 euroifbromatosis, 1 mixed hemangioma, 5 gastrocnemius hematoma. After diagnosis of ICMVT, all patients prescribed thrombolysis and anticoagulation therapy. High-frequency color Doppler ultrasound for 1, 3, 6 months after treatments revealed partial or complete recanalization without calf deep vein thrombosis. Typical sonographic features included:calf muscle venous lumen dilation, tortuous anechoic lumen or hypoechoic iflling, with tubular or branched shape in the longitudinal view and oval or round shape in the transversal view. Conclusion High-frequency color Doppler ultrasound is an accurate and reliable method in the diagnosis of the isolated calf muscular venous thrombosis.

Objective To investigate the value of color Doppler flow imaging(CDFI) in diagnosing lower limb artery in-stent restenosis (ISR), and to provide the evidences for clinical application. Methods Patients with lower limb artery percutaneous transluminal stent insertion in 12 months were enrolled in this study and divided into two groups, CT angiography (CTA) or digital subtraction angiography (DSA) was applied to diagnose ISR, 31 patients with 47 stenting which were diagnosed ISR was named as restenosis group, 63 patients with 89 stenting which were diagnosed no ISR was named as no stenosis group, and 30 normal person was enrolled and named as normal control group. Ultrasonic characteristics and peak systolic blood flow velocity (PSV), systolic blood flow acceleration time (AT) of proximal part, inner stents, distal part were recorded in restenosis group and no stenosis group, then compared with data in normal control group. Regression and receiver operator (ROC) curve were applied to analyse the correlation between PSV and AT. Results PSV of no stenosis group in common femoral artery, femoral artery, superifcial, popliteal artery stent respectively were (146.71±35.59) cm/s, (120.11±25.67) cm/s, (96.44±32.87) cm/s. PSV of normal control group in common femoral artery, femoral artery, superifcial, popliteal artery respective were (119.67±15.34) cm/s, (91.17±15.09) cm/s, (71.13±21.23) cm/s. There was statistically signiifcant difference between the two groups (t=2.457, 2.459, 2.321, all P<0.05). AT of no stenosis group in common femoral artery, femoral artery, superficial, popliteal artery stent respectively were (84.98±13.77) ms, (87.33±16.36) ms, (90.77±12.05) ms. AT of normal control group in common femoral artery, femoral artery, superficial, popliteal artery respective were (78.23±21.24) ms, (82.31±18.24) ms, (84.29±23.01) ms. There was no statistically signiifcant difference between the two groups (t=1.696, 1.904, 1.835, all P>0.05). PSV of restenosis group in proximal part, restenosis part, distal part respectively were (87.67±23.34) cm/s, (218.17±72.09) cm/s, (54.13±21.23) cm/s. PSV of no stenosis group in proximal part, inner stents, distal part respectively were (91.71±25.59) cm/s, (131.11±45.67) cm/s, (96.44±32.87) cm/s. There was statistically significant difference between restenosis part/inner stents, distal part (t=3.412, 3.511, both P<0.05). There was no statistically signiifcant difference between the two groups in proximal part (t=1.901, P>0.05). AT of restenosis group in proximal part, restenosis part, distal part respectively were (98.31±14.09) ms, (109.54±21.03) ms, (158.23±45.21) ms. AT of no stenosis group in proximal part, inner stents, distal part respectively were (84.98±13.77) ms, (86.34±19.36) ms, (83.77±17.05) ms. There was statistically signiifcant difference between restenosis part/inner stents, distal part (t=2.319, 3.610, both P<0.05). There was no statistically signiifcant difference between the two groups in proximal part (t=1.833, P>0.05). ROC curve showed that in ISR lower limb artery, PSV>168 cm/s had a sensitivity of 89.4%, speciifcity of 92.1%, the area under the ROC curve was 0.949;AT>127 ms, had a sensitivity of 86.8%, speciifcity of 98.0%, the area under the ROC curve was 0.867. Conclusions CDFI can detect the changes of PSV and AT, ISR can be detected and diagnosed earlier in lower limb artery. By combining PSV>168 cm/s with AT>127 ms, the value of ISR diagnosis can be increased.
