The evaluation of quality of life after stroke primarily includes body,psychology, society,and the ability of activities of daily living,and they can be mainly obtained from self rating quality of life by the patients,The commonly used evaluation methods include six generic measurement scales and four updated Stroke Specific Quality of Life Scales.The latter includes the Stroke Adapted Sickness Impact Profile,the Stroke Impact Scale,Stroke Specific Quality of Life Scales,and Stroke and Aphasia Quality of Life Scale.This article reviews the generic meas- urement scales,Stroke Specific Quality of Life Scales and the various factors that influencing quality of life after stroke.

Objective To explore the clinical application of microsurgical techniques to therapy the femoral neck fracture in younger patients and prevent the necrosis of femoral head.Methods Seventy-four younger adults,age from 23 to 50,with femoral neck fractures were treated by open veducition,internal fixa- tion and pedicled bone transplantation from Jan.1995 to Dec.2004.All of the 74 patients were reviewed clin- ically and radiologically after an average of 3.2 years.Results In this group,19/74 cases(25.68%)had avaseular necrosis of the femoral head,which were diagnosised after an average of 28.5 months following inju- ry.Despite these results,these patients assessment with Harris system had been very good or good in 55/74 patients(74.32%).Conclusion It's an effective method to decrease the incidence of necrosis of femoral head after management the femoral neck fracture in younger patients by microsurgical techniques.

Urokinase plasminogen activator receptor (uPAR) is a membrane protein which is attached to the cellular external membrane. The uPAR expression can be observed both in tumor cells and in tumor-associated stromal cells. Thus, in the present study, the human amino-terminal fragment (hATF), as a targeting element to uPAR, is used to conjugate to the surface of superparamagnetic iron nanoparticle (SPIO). Flowcytometry was used to examine the uPAR expression in different tumor cell lines. The specificity of hATF-SPIO was verified by Prussian blue stain and cell phantom test. The imaging properties of hATF-SPIO were confirmed in vivo magnetic resonance imaging (MRI) of uPAR-elevated colon tumor. Finally, the distribution of hATF-SPIO in tumor tissue was confirmed by pathological staining. Results showed that the three cells in which we screened, presented different expression characteristics, i. e., Hela cells strongly expressed uPAR, HT29 cells moderately expressed uPAR, but Lovo cells didn't express uPAR. In vitro, after incubating with Hela cells, hATF-SPIO could specifically combined to and be subsequently internalized by uPAR positive cells, which could be observed via Prussian blue staining. Meanwhile T2WI signal intensity of Hela cells, after incubation with targeted probe, significantly decreased, and otherwise no obvious changes in Lovo cells both by Prussian blue staining and MRI scans. In vivo, hATF-SPIO could be systematically delivered to HT29 xenograft and accumulated in the tumor tissue which was confirmed by Prussian Blue stain compared to Lovo xenografts. Twenty-four hours after injection of targeting probe, the signal intensity of HT29 xenografts was lower than Lovo ones which was statistically significant. This targeting nanoparticles enabled not only in vitro specifically combining to uPAR positive cells but also in vivo imaging of uPAR moderately elevated colon cancer lesions.

IgG4-related disease (IgG4-RD) has been proved to be associated with malignancy.The incidence and risk factors of malignancy development in IgG4-RD were not clear.Nine IgG4-RD patients with malignancies and 27 IgG4-RD control cases were analyzed for risk factors and clinical features.The incidence of malignancy in IgG4-RD was 3.3％,higher than age-controlled general population.Smoking history was significantly more common in patients with malignancies than in the control group (9/9 vs 16/27,P ＜ 0.05).A total of 6/9 malignancies occurred within the first year after the diagnosis of IgG4-RD.Colorectal,biliary and thyroid cancers were the leading types.Smoking history is a risk factor for IgG4-RD associated malignancy.Careful vigilance to monitor malignancy needs to be paid during follow-up.

Objective To evaluate the value of ultrasound elastography score and strain ratio index in the differential diagnosis of thyroid solid nodules. Methods Eighty-six thyroid solid nodules of 69 patients were divided into 2 groups based on their pathologic results: benign nodules group and malignant nodules group.Compared with pathological results, each thyroid solid nodules' elastographic scores and strain ratio index were respectively analyzed. The sensitivity, specificity and accuracy of elasticity score and strain ratio index were calctlated.The receiver operator characteristic (ROC) curves were drawn according to the results, to choose the best cut-off value.Results There were 67 nodules in benign nodules group and 19 nodules in malignant nodules group. The diameter of benign nodules was (2.05 ± 0.21)cm, malignant nodules was (1.62 ± 0.12)cm. There were no significant differences in the elasticity score and strain ratio index between benign and malignant nodules(t= - 1.736, P ＞ 0.05). Malignant lesions had a higher score and strain ratio index(median 3, 3.97, respectively) than benign ones(median 2, 1.66,respectively, Z = - 5.290, - 5.450, all P ＜ 0.05). If the cut-off value of the elastographic scores was equal or more than 3, the sensitivity, specificity and accuracy were 84.2%(16/19) ,86.6%(58/67) and 86.0%(74/86), respectively,with an area under ROC curve of 0.854. If the cut-off value of the strain ratio index was equal or more than 2.50,the sensitivity, specificity and accuracy were 89.4%(17/19),86.6%(58/67) and 87.2%(75/86), respectively, with an area under ROC curve of 0.911. Conclusion Elasticity score and strain ratio index are helpful in differentiating benign and malignant lesions of thyroid with high clinical value.

Conventional randomized controlled trial is considered as the gold standard of clinical trials in evalua ting pharmacologic effectiveness. Whereas, it still has some faults in the non-pharmacy interventions, such as surgery, acupuncture, massage, etc. Expertise-based randomized controlled trial makes up for some deficiencies of conventional randomized controlled trial, which has made better developments in the field of surgery, however, there is no any relevant retrieval literature found in the acupuncture field. It is feasible and practical of the expertise-based randomized controlled trial to be applied and promoted in the acupuncture-moxibustion clinical research for a further degree. Expertise-based randomized controlled trials might become the trend of acupuncture-moxibustion clinical stu dies in the future.

Objective To summarize the clinical features of the third portion of duodenum (PATD) for improving the understanding of PATD.Methods Sixteen cases with PATD in Peking Union Medical College Hospital(PUMCH) were retrospectively analyzed.Results The most common symptoms of PATD were upper abdominal pain(12/16),vomiting (9/16) and distention (7/16).On average,the disease had progressed 5.5 months (including 2.5 months of diagnostic workup) before the diagnosis was established.Patients with pathologically poorly differentiated PATD had shorter course of disease (6.5 vs 16.6 months,P =0.56) and lower chance of cancer-directed surgery (1/8 vs 6/8,P =0.04) than those with well differentiated PATD.The diagnostic rate was 11/14 by CT scan while only 2/7 by upper gastrointestinal radiography.Three cases were misdiagnosed as superior mesenteric artery syndrome by barium examination.Conclusions PATD should be considered in patients presenting upper abdominal symptoms with negative gastmendoscopy and barium examination.Overall,CT scan plays a pivotal role in diagnosing PATD.Making a correct diagnosis timely can improve the outcome of PATD patients,particularly,in those with poorly differentiated pathology.
