Objective To characterize the medial femoral circumflex artery based on three-dimensional computed tomographic angiography (3DCTA) so as to provide anatomical aids for diagnosis and treatment of hip injuries.Methods To do this research the 3DCTA data of 103 patients (206 hips) were collected who underwent 3DCTA from March 2012 to June 2014 for examination of the pelvis and lower extremities.They were 55 men (mean age,54.7 ± 15.9 years) and 48 women (50.0 ± 16.1 years).① The origin and course of the medial femoral circumflex artery was observed.② The length of the artery trunk was measured.The distances between the origin(A) of the artery to the main anatomical marks [the peak of greater trochanter (B),the inward peak of lesser trochanter (C),and the crosspoint (D) of the femoral artery and the pubic edge or the acetabulum inlet edge] were measured.Comparisons of the measurements were conducted between genders.③ The distance between point A and point E,the starting point of the femoral profound artery,was measured.Comparisons of the measurements were conducted between genders.Results 2.9％ (3/103) of the subjects had their bilateral medial femoral circumflex arteries originate from the femoral artery,94.2％ (97/103) had their bilateral medial femoral circumflex arteries originate from the femoral profound artery,and 2.9％ (3/103) had one medial femoral circumflex artery originate from the femoral artery and the other from the femoral profound artery.1.9％ (4/206),76.7％ (158/206) and 21.3％ (44/206) of the subjects had the artery of screw type,of circuitous type and of straight type,respectively.The artery trunk goes posteriorly and medially after it is issued,divides into branches along the course,continues to go around the back of the femoral neck,and finally goes to the outward and upper direction.There were no statistical differences between males and females regarding length of the artery trunk,or distances between points AB,AC,AD or AE (P ＞ 0.05).Conclusion Since 3DCTA can clearly demonstrate the origin,course and anatomical morphology of the medial femoral circumflex artery,it can be used to provide anatomical aids for clinical evaluation and treatment of hip injury.

The training of clinical skill is closely linked with medical personnel education.However,traditional paper-type training materials were unable to meet the training needs.As a new type of training materials,trial-and-error video-type clinical skill training materials (abbreviated as TEVT clinical skill training materials) have gradually attracted attention with its characteristics of lively and interesting,potentially informative,high acceptance among students,the advantages' of stimulating students' initiative exploration and consideration,fostering students' critical spirit and humanities.On the basis of analyzing the advantages' of TEVT training materials,we discussed the developing specialties of TEVT clinical skill training materials from four aspects as the material orientation and the application object,material sources,constructing the developing team and editing the teaching materials.Furthermore,we reflected the application prospect of TEVT clinical skill training materials in the future,in order to explore an available implementation path for the development of TEVT clinical skill training materials.

Objective To summarize the experience in nursing 2 patients with anti-glomerular basement membrane disease.Method The nursing measures such as close observation of disease condition,careful nursing of medication,nursing during the treatment of double filtrated plasmapheresis and mental care to the patients and their family members.Results After treatment,the concentration of anti-GBM antibody was declined and the level of serum creatinine was also decreased.The renal function got rccovered to a certain extent.Conclusion Such nursing points as close observation of renal and pulmonary pathgenesis,timely and accurate administration of medicine according to doctor's orders and active observation and prevention of complication from double filtrated plasmapheresis are key.

Objective To observe the expression of protein kinase C(PKC)isoforms in pulmonary artery of chronic inflammatory pulmonary hypertension(PHT)rats.Methods Chronic inflammatory PHT model rats were established induced by monocrotaline(MCT).Western blotting analysis was used to detect the expression of four PKC isoforms(PKC?,PKC?Ⅱ,PKC? and PKC?)in pulmonary arteries of rats during the development of PHT.Results The values of mean pulmonary artery pressure and right ventricular hypertrophy index increased significantly after the injection of MCT,which suggested successful formation of PHT.Western blotting analysis showed that PKC?,PKC?Ⅱ and PKC? isoforms were presented in pulmonary arteries of normal and PHT rats,while PKC? isoform was not detected.The expressions of PKC? in both cytosolic and membranous fractions increased within 14 days,and decreased a little during the development of PHT.But the increase of PKC? in cytosolic fraction was much more obvious than that in membranous fraction.The highest expression of both PKC?Ⅱ and PKC? in cytosolic fractions appeared at the eighth day,while the expression of both isoforms in membranous fraction went up continuously.Conclusions PKC?,PKC?Ⅱ and PKC? isoforms were involved in the development of chronic inflammatory PHT.The changes of their expression might be the results of PKC isoforms translocation which is related to the proliferation regulation of pulmonary artery smooth muscle cells.

OBJECTIVE To investigate the application of blood test in the prognosis of nasal NK/T-cell lymphoma.METHODS The clinicopathologic and follow-up data of 62 patients with nasal NK/T-cell lymphoma proven by pathological examination were collected.The blood lactic dehydrogenase(LDH),globulin(GLB),albumin(ALB),hemoglobin(Hb),and white blood cell(WBC) were examined in these patients.The correlation between these factors and prognosis were analyzed with univariate analysis and multivariate analysis.RESULTS Of the 62 patients,47 were males and 15 were females.Their median age was 42 years.Ninety two percent of the patients were in Ann Arbor I/Ⅱ stage,and 76 % had international prognostic index(IPI) of 0 or 1.Before treatment,92 % of the patients had ECOG performance status(PS) score of 0-1,26 % had anemia,53 % presented B symptoms.The median overall survival time was 27 months(95 % CI:10-45months).In univariate analysis,gender,age,PS score,LDH,IPI,B symptoms,Hb and WBC were statistically significantly correlated to the prognosis.In multivariate analysis,Hb1 were statistically significant unfavorable prognostic factors.CONCLUSION Hb together with B symptoms and PS score may be independent prognostic factors for nasal NK/T cell lymphoma.

Objective To investigate the characteristics of cognitive changes in type 2 diabetes mellitus pa-tients complicated with stroke. Methods One hundred and one stroke patients were recruited and allocated to thetype 2 diabetes mellitus group (34 patients) and sixty-seven patients in the control group (67 patients) according tobeing with or without type 2 diabetes mellitus. All the patients were evaluated, after 3 weeks, 6 months and 12months of onset of stroke, with regard to their cognitive functions by using the Mini-mental State Examination(MMSE) and Montreal Cognitive Assessment (MOCA). Results Average scores obtained in MMSE and MOCAtests were significantly lower at 3 weeks and 6 months after onset in the type 2 diabetes mellitus group when comparingwith control group. In the type 2 diabetes mellitus group, no significant difference was observed between 3 weeks and6 months after onset of stroke with regard to scores of MMSE and MOCA ( P > 0.05 ), however, the score at 6 monthswas significantly lower than that at 12 months after onset (P <0.05). On the other hand, scores of MMSE (P >0.05 ) and MOCA (P > 0.05 ) in the control group were not any statistically different among various time points ofobservation. Conclusion Type 2 diabetes mellitus will aggravate cognitive dysfunctions of stroke patients, whichstarted to recover in 6 months of onset of the stroke.

4 ng/ml and/or with prostate nodule found on DRE or TRUS . Methods 197 patients suspected of prostate carcinoma underwent ultrasound guided sextant biopsy and 2～4 more cores in the nodule. Four patients whose initial biopsy was negative but subsequent PSA levels were continuously abnormal underwent repeated biopsies. Results Of the 107 cases with prostate nodules,in 34(31.8%) of them prostate cancer was detected,while in 90 cases without a prostate nodule, only 11(12.2%) were positive. Stratified analysis on PSA found that the higher the PSA, the higher the positive biopsy rate of prostate carcinoma. In the 4 cases with repeated biopsies, 1 prostate cancer was detected. Conclusions For patients with prostate nodule and/or PSA over 4 ng/ml,systematic biopsy should be taken, with 2 or more cores toward the nodule.In the patients with continuous high PSA levels,if the first biopsy is negative, rebiopsy should be taken.
