Objective To investigate the relationship of proximal femur geometry and hip fracture in elderly women. Methods We compared proximal femur measurements made from the uninvolved hip of 48 plane anteroposterior pelvis radiographs of elderly women without fracture to those of the contralateral hip in a group of 43 cases with hip fracture. Measurements of Singh index, head diameter(HD), neck diameter(ND), femoral neck length(NL), neck shaft angle(NSA) and cortical thinckness of proximal femur were analyzed. Results The cortical thickness of proximal femur in hip fracture and without hip fracture groups was (10.9?3 1) mm and (13 2?2 9) mm, and the Singh index below Ⅲ? was 86 05% and 66 67%, respectively. No difference in HD,ND,NL and NSA could be demonstrated. Conclusions Singh index and cortical thickness of proximal femur may be used to predict the occurrence of the hip fracture in elderly women.

The cerebral infarction model was made according to Chen et al To evaluate the severity of infarction the quantity of Evan's blue was measured. The cerebral infarction size was determined by TTC stain. The results showed that ligating the right common carotid artery and the right middle cerebal artery and clamping the left common carotid artery could induce cerebral cortex in farction. Berbamine could decreased the level of Evan's blue and reduce the infarction size compared with control group. It suggests that berbamine possesses protective effect on experimental induced cerebral infarction.

BACKGROUND: Inhaled glucocorticoids(IGC) are powerful anti_inflammatory agents used in the treatment of asthma. But it is still uncertain whether long-term use of the IGC affects bone metabolism in asthmatic patients, especially women.OBJECTIVE: To investigate if the prolonged treatment with IGC to Chinese asthmatic woman has a detrimental effect on bone mass and metabolism.DESIGN: A matched controlled study based on the patients SETTING:Clinical Laboratory and the Department of Respiratory Medicine, First Affiliated Hospital, Nanjing Medical University.PARTICIPANTS: From February 1998 to February 2002, forty female Chinese patients with bronchial asthma, regularly followed up at our outpatient clinic, all in the Nanjing area, none of them having a history of chronic systemic GC use, agreed to take part in the study, were selected and divided into two groups: therapeutic group (IGC group): 20 asthmatic women, aged 18-63 years, 5 menopausals, received IGC therapy regularly for at least 5 months; Control group: 20 asthmatic women, aged 18-60 years, 5 menopausals, never received IGC received conventional bronchodilators . They were matched individually for sex, age and menopausal status.METHODS: Bone mineral density (BMD) at the lumbar spine (2-4),femoral neck, trochanter, ward's triangle and total body of femur were measured by dual energy X-ray absorptiometry, BMD were expressed as a absolute value and a T score considered as a SD from peak bone mass respectively. Meanwhile, BMD was also expressed as a percentage (%), which was defined by comparing the BMD absolute value of subjects and BMD normal value of isosexual age cohorts. Osteocalcin and some other markers of bone metabolism were measured by radio immunoassay in two groups.daily dose and accumulative total dose of IGC and BMD in the IGC group.RESULTS: There were no significant difference between two groups in BMD and T score (including the lumbar spine (2-4), femoral neck,trochanter, ward' s triangle and total body of femur) (P > 0.05). There were also no significant correlation between daily dose of IGC and BMD of above 5 parts in the IGC group (r=-0.325 to -0.1102, P > 0.05). But,there were significantly negative correlation between the accumulative total dose of IGC and BMD at lumbar spine2-4,femoral neck and ward's triangle(r=-0.495 ,-0.517,-0.531 ,P < 0.05).There were no significant correlation between the accumulative total dose of IGC and T score of above 5 parts in the IGC group (r=0.443to 0.295 ,P > 0.05). There was negative correlation between the age and the BMD at ward's triangle in the IGC group(r=-0.506,P < 0.05). However ,BMD at 5 locus were not correlated with the age in control group (r=-0.079 to 0.326, P > 0.05).Osteocalcin and some other markers of bone metabolism were no significant difference between two groups (P > 0.05).CONCLUSION: The data suggests that there is no significant influence of IGC on bone mineral density and bone metabolism in asthmatic women,but if continuing exposures to high doses over many years,there may be a detrimental effect on bone mass and metabolism in women, especially elder or postmenopausal asthmatic women treated with IGC who may be more susceptible to any bone mineral loss caused by IGC.

Purpose To explore the clinical value of131I-whole body scan (131I-WBS) and 18F-FDG PET/CT on the metastatic management of patients with differentiated thyroid cancer (DTC) after operation.Materials and Methods Serum thyroglobulin (Tg) of 27 patients after DTC surgery was measured one day before131I therapy, and the patients underwent131I-WBS on 3-5 days after131I therapy. According to the results of Tg and 131I-WBS, all the patients were divided into 4 types as follows: type I: Tg (+),131I-WBS (-); type II: Tg (+),131I-WBS (+); type III: Tg (-),131I-WBS (+); and type IV: Tg (-), 131I-WBS (-). Then the patients received18F-FDG PET/CT scan within a week after 131I-WBS. The results of131I-WBS and18F-FDG PET/CT scan were analyzed according to histopathologic findings or clinical and imaging follow-up of at least 6 months as diagnosis standard.Results The examinations uncovered that metastasis occurred in 52 lesions of 22 cases out of the 27 cases.131I-WBS revealed 24 metastatic lesions (46.2%) in 8 cases (36.4%), and18F-FDG PET/CT showed 35 metastatic lesions (67.3%) in 15 cases (68.2%), the difference with statistic significance (χ2=4.46 and 4.74,P<0.05). Metastasis were confirmed in 13 type I cases (100.0%); 5 type II cases (100.0%); 3 type III cases (100.0%) and 1 type IV case (16.7%), respectively. The rate of detecting metastasis by 18F-FDG PET/CT was 100.0% in type I, 20.0% in type II, 0% in type III respectively, the difference with statistic significance (χ2=9.14 and 10.11,P<0.05); and 100.0% in type IV, the difference without statistic significance (χ2=1.25,P>0.05). Based on that, therapeutic plans were modified for 13 patients with type I metastasis and 1 patient with type IV metastasis.Conclusion131I-WBS and18F-FDG PET/CT are complementary for detecting metastatic lesion and help to decide the following treatment of DTC patients after surgery. Moreover,18F-FDG PET/CT shows advantages in detecting metastatic lesion in Tg-positive and negative131I-WBS type of DTC patients after surgery, thus can provide an important clinical guidance for this type of patients.

Background:Chronic inflammation is closely associated with occurrence and development of gastric cancer,and inflammatory cytokines,interleukin-18(IL-18)and IL-1β are involved via a variety of mechanisms. Aims:To determine the serum levels of IL-18 and IL-1β in patients with different gastric mucosal lesions and to explore the role of these two cytokines in gastric cancer and their clinical significance. Methods:Serum levels of IL-18 and IL-1β were detected by ELISA in patients with different gastric mucosal lesions,including 324 gastric cancer,40 chronic non-atrophic gastritis (CNAG),13 chronic atrophic gastritis with or without intestinal metaplasia(CAG/ IM)and 20 mild to moderate dysplasia. Helicobacter pylori(Hp)IgG antibody was detected in patients with gastric cancer. Correlations of serum levels of IL-18 and IL-1β with clinicopathological parameters and Hp infection were analyzed in patients with gastric cancer. RoC curve was used to assess the performance of serum IL-18 and IL-1β for diagnosis of gastric cancer. Results:Serum levels of IL-18 and IL-1β increased gradually from CNAG,CAG/ IM,dysplasia to gastric cancer;except for IL-1β between CNAG and CAG/ IM groups,significant differences were found between any two groups(P < 0. 05). In gastric cancer group,they were positively correlated with tumor size,lymph node and distant metastases,depth of invasion,TNM stage and Hp infection(P < 0. 05). Area under the RoC curve(AUC)of combined detection of serum IL-18 and IL-1β for diagnosis of gastric cancer was superior to that of IL-18 or IL-1β detection alone(0. 867 vs. 0. 837 and 0. 795). Conclusions:Serum levels of IL-18 and IL-1β increase dynamically with the tumorigenesis of gastric cancer,and are closely related to growth, invasiveness and metastasis of gastric cancer. Combined detection of serum IL-18 and IL-1β might be used as a biomarker for diagnosis and tumor progression and prognosis assessment of gastric cancer.

Background:The incidence of inflammatory bowel disease( IBD ) is increasing in recent years,however,its pathogenic mechanism has not been fully clarified. Previous studies revealed that adipokines played crucial roles in regulating intestinal inflammation. Aims:To investigate the role of visfatin,an adipocytokine,and its clinical significance in active IBD. Methods:Ninety-one patients with active IBD including 61 Crohn’s disease( CD)and 30 ulcerative colitis ( UC)at the First Affiliated Hospital of Soochow University and Suzhou Municipal Hospital from May 2015 to Dec. 2015 were enrolled in this study,and 48 healthy subjects were served as controls. Serum level of visfatin was determined by ELISA. Correlation of serum visfatin level with clinical features of IBD was analyzed,its diagnostic performance for IBD was assessed by ROC curve. Results:Serum level of visfatin was significantly higher in patients with active CD and UC than in healthy controls[(385. 24 ± 112. 64)pg/mL and(378. 91 ± 118. 57)pg/mL vs. (321. 11 ± 96. 27)pg/mL, P all ﹤0. 05]. Significant positive correlation was found between serum visfatin level and disease activity index(Mayo score)of UC( r =0. 398,P ﹤0. 05 ),however,no correlations were found between serum visfatin level and disease activity index of CD,CRP and ESR,two common inflammatory indicators for IBD and location of IBD(P all ﹥0. 05). The area under curve( AUC)of serum visfatin for diagnosis of CD and UC were 0. 654 and 0. 622,respectively;the diagnostic accuracy was relatively low. Conclusions:Serum visfatin might be associated with the active intestinal inflammation in IBD and has the potential to be served as a clinical index for active UC.
