Objective To study the diagnostic value of color Doppler ultrasonography in hematoma of soft tissues, and compare the images of different period of hematoma. Method Analyzed and compared the size,shape and sonographic characteristic of 46 cases with hematoma. Results The images of hematoma were round or oval in shape, more than 2.0 cm in trans-diameter, and were isoechoic or hypocchoic in the early stage, then anoechoic areas increased with hyperechoic septum and irregular hypoechoic, with posterior enhancement and hyperechoic boundary. A part of muscle fibres raptured and were occupied by the hematoma if the muscle tore. Conclusion Color Doppler ultrasonography can be the first choice and reliable imaging method to diagnose hematoma of soft tissues.

Currently,the overall situation of information literacy level of researchers in hospitals is generally low.This paper explores the connotation of information literacy and stresses the importance of information literacy cultivation for scientific researchers.Suggestions are also made for cultivation of information literacy.

To observe the patients with type 2 diabetes who were injected premixed insulin analogues after short time continuous subcutaneous insulin infusion( CSII ) treatment.It was found that the patients needed premixed insulin analogue injection 2 times daily when the dosage of CSII was less than 45 U/d,and 3 times daily when the dosage was greater than 45 U/d.The relationship of dosages between premixed insulin analogue treatment ( Y ) and CSII treatment(X) was calculated by following equations:2 times daily premixed insulin analogue treatment:Y =13.093 +0.395X,3 times daily premixed insulin analogue treatment:Y =23.114+0.405X.

The traditional Najiafa (day-prescription of acupoints) can be classified into two schools of YAN Ming-guang and XU Feng. The author studied the YAN Ming-guang and XU Feng Najia fa from the aspects of the academic source, selection of points, existing researches and current application. When compared between the two schools, it is held that Najia fa of YAN Ming-guang school more accords with the law of point selection according to Ziwu Liuzhu Zhenfa (acupuncture based on the midnight-noon and ebb-flow doctrine) in following the original doctrine, selection of points on the base of day-prescription, and time-meridian relation of Sanjiao (triple energizer) and Pericardium meridians. Therefore, it is concluded that the YAN's Najia fa should not be neglected and forgotten. Its inheritage and further study should be carried out so as to enrich the ways of study as well as the prevention and treating methods in clinic.

This article summarizes the effects of intense exercise on the structure and function of the kidney,the possible mechanism of the changes of the structure and function of the kidney and the research state of the improvement of the function of the kidney by the medicine.The research suggests the intense exercise will lead to the damage of the renal tubules and the glomerulus,the increase of the LPO of the kidney tissue,the decrease of the activity of SOD,the appearance of the exercise-induced albuminuria,exercise-induced hematuria.Vitamine E,Vitamine C,GSH have some protective effect on the structure and function of the kidney.

As a kind of new technology, ethical issues are inevitable in medical and non-medical gene en-hancement application. It is unrealistic to unilaterally support or object to the research and application of medical and non -medical gene enhancement. Based on standardizing the ethical principle of gene enhancement tech-niques, we should build management measures of the research, development and application that adapted to ethi-cal, social and legal standards, so that we can draw on the advantages and avoid the disadvantages, and use gene enhancement reasonably and bring benefits to mankind and society.

Objective To explore the MRI characteristics of saddle transverse carpal ligament (TCL)of patients with idiopathic carpal tunnel syndrome (CTS). Methods The clinical diagnosis of 21 cases of idiopathic CTS patients (22 wrists) were retrospectively analyzed and as the idiopathic CTS group. Thirty two patients without CTS symptoms or TCL and volar soft tissue lesions (33 wrist joints) were selected as the control group. Patients in two groups were both conducted with sagittal and axial MRI scan of wrist joint to observe the form of the TCL, determine whether the TCL saddle and calculate the TCL palmar concave curvature and the median nerve compression rate. The differences of the morphology of the TCL of patients in two groups were compared by Chi?square criterion, and the difference of the TCL palmar concave curvature were compared by non parametric test. The relativity of TCL palmar correlation concave curvature and compression ratio of the median nerve of patients with idiopathic CTS was evaluated by the Pearson correlation analysis.Results The sagittal plane of patients with idiopathic CTS was upper, saddle shaped TCL was dented to the palmar and the concave point most frequently located in the hamate hook. Thirty one patients were with saddle shaped TCL (20 patients with idiopathic CTS and 11 patients in the control group) and 24 patients were with non saddle shaped TCL (2 patients with idiopathic CTS and 22 patients in the control group) as the standard of saddle shaped TCL concave 0.25 mm and the difference of the morphology of the TCL of patients in two groups had statistical significance (χ2= 17.791, P<0.01). The median of TCL palmar concave curvature of patients with idiopathic CTS and patients in the control group was 8.49%and 0.00%, respectively, the difference of which was statistically significant (Z=-4.79, P<0.01). The level of the median nerve, the TCL palmar concave curvature [(7.88+4.28)%] and the median nerve compression rate [(39.36 + 19.43)% ] of patients with idiopathic CTS were positively correlated (r=0.714, P<0.01). Conclusions Saddle shaped TCL is the characteristic manifestation of patients with idiopathic CTS. The TCL sagittal concave palm and median nerve compression percentage rate are both helpful to the accurate diagnosis.

Objective To explore the effect of interventional ward to the development of interventional radiology.Methods Investigation of the first class of the third grade hospitals in northeast region of China for the development status of interventional radiology in 2005 through questionnaires was undertaken.The hospitals were divided into two groups according to setting up interventional ward or not,together with comparative studies of number of doctors,sorts of interventional techniques and number of cases.Results Altogether 52 3rd grade,1st class hospitals have established interventional therapy,including with ward of 29(55.8%)and no ward of 23(44.2%);furthermore the average numbers of doctors in the forementioned two kinds of hospitals were 4.8 ? 1.7 vs 2.8 ? 1.5(P
