Objective To assess the diagnostic value of the single-photon-emission computed tomography (SPECT) and the magnetic resonance imaging (MRI) for Alzheimer's disease (AD) and vascular dementia (VD), and to explore the correlation between cerebral atrophy and cerebral regional blood flow and the degree of cognitive impairment in AD patients. Methods The temporal and frontal lobes and hippocampus were quantitatively detected by MRI and the cerebral regional blood flow in these regions was analysed semi-quantitatively by SPECT for 36 patients with AD, 32 with VD and 30 sex-matched non-demented elderly controls (NC). Results The hippocampal atrophy of AD and VD groups detected on MRI was significantly different from that of the NC group. Left hippocampal height was (9.27?3.43)mm in AD, (11.62?5.72)mm in VD and (12.13?2.97)mm in NC(P0.05, compared to that of NC), showing that hippocampal atrophy could not be detected by MRI. However, RAR of the left hippocampus by SPECT detection was 0.61?0.07 (P

Objective To investigate the clinical significance of anti-nuclear envelope protein antibody (gp210),anti-soluble acid resistant nucleoprotein (sp100) and anti-mitochondrial antibody M2 subtype (AMA-M2) in sjogren syndrome (SS) and primary biliary cirrhosis (PBC).Methods A total of 241 hospitalized patients diagnosed with connective tissue disease (CTD) were recruited.Anti-gp210,anti-sp100 and AMA-M2 were detected by indirect immunofluorescence.Results (1) Positive rate of AMA-M2,anti-sp100 and antigp210 in 241 cases CTD patient were 10.4％ (25/241),3.3％ (8/241) and 2.9％ (7/241) respectively.(2) There were 16 cases with SS,5 cases with SS-PBC overlap syndrome and 17 cases with PBC in 241 patients with CTD.Distinction among groups of PBC,SS,SS overlapping PBC of positive incidence of AMA-M2 antibody (x2 =6.584,P =0.03) and anti-gp210 (x2 =8.735,P ＜ 0.01) were significantly different,while there was no apparent difference about positive rate of anti-sp100 among the three groups (x2 =3.343,P =0.18).(3) Positive expression of either antibody of anti-gp210 or anti-sp100 in the three groups of SS,SS overlapping PBC,PBC were 3 cases,4 cases,4 cases respectively.The positive rates of any of three autoantibodies in three groups of were 8 cases,5 cases,13 cases respectively.(4) There were significant difference in terms of serum ALB(t =3.858,P＜0.000 1),TSB(t =5.473,P＜0.000 1),ALT(t =2.235,P=0.026),AKP(t =3.141,P =0.002) and γ-GT (t =2.317,P =0.021) in liver damaged patients of all CTD between AMA-M2 positive and negative patients (P ＜ 0.05).However,serum TSB in anti-sp100 positive and negative patients were differed (t =7.892,P ＜ 0.000 1).Serum AKP was different between anti-gp210 positive and negative patients (t =2.451,P =0.015).Conclusion Positive rate of anti-gp210,anti-sp100 and AMA-M2 are the highest in patients with SS overlap of the PBC among CTD patients.Combined detection can improve the sensitivity of diagnosis.Antisp100 and anti-gp210 are valuable for the diagnosis of SS-PBC overlaps syndrome with negative AMA-M2.

Background and purpose:Stromal tumor is one of the common gastrointestinal mesenchymal tumors. There is certain understanding about the typical cases. However, the diagnosis of those occurring in rare location or with rare imaging findings is often difficult. This research summarized this kind of cases,in order to increase the radiological knowledge of the disease.Methods:This study retrospectively analyzed clinical, radiological and pathological data from 550 patients who had stromal tumor conifrmed by pathology in our hospital. Those with incomplete data were eliminated. Forty-nine patients were selected for further study according to the typical imaging findings.Results:Among these 49 patients, 9 were pathologically confirmed to have extra-gastrointestinal stromal tumor, while 40 patients had gastrointestinal stromal tumor. Among the patients with gastrointestinal stromal tumor, 22 were found in rare locations, 12 in retroperitoneal space, 3 in omentum majus and mesenterium, 5 in esophagus, and 2 in prostate. Obvious cystic degeneration was found in 16 patients. Bulky calciifcation, such as lfake or annulus, was found in 7 patients. The analysis result of risk-stratiifcation showed 19 patients were conifrmed as high-grade among the patients with tumors found in rare locations, 15 as high grade among those with obvious cystic degeneration, and 7 as high-grade among those with extra-gastrointestinal stromal tumor.Conclusion:Rare stromal tumor often occurs in the locations, such as retroperitoneal space, omentum majus and mesenterium. Obvious cystic degeneration and bulky calciifcation can be seen. The risk-stratiifcation of these patients often showed high-grade. Comprehensively analyzing its clinical features and imaging ifndings can help improve the diagnostic accuracy.

OBJECTIVETo explore the effect of half circle external fixation for the treatment of open tibial fractures.

METHODSFrom March 2005 to March 2011, 94 patients with open tibiofibula fractures were treated by closed manipulative or Kirschner-wire poking reduction with half circle groove external fixation including 63 males and 31 females with an average age of 39 years old ranging from 17 to 65 years old. Among these patients, 5 cases were cross shaped fractures, 19 were oblique form and spiral fractures, 70 cases were comminuted fractures. According to the fracture Gustilo classification, 49 cases were type IIIA, 45 were type IIIB. The incidence of wound infection, fracture healing time were observed. The function was evaluated according to the Johner-Wruhs standard.

RESULTSAll patients were followed up for 14 to 63 months (averaged 29 months). The wound healing time was from 16 to 39 weeks (means 21.4 weeks). No fracture nonunion, osteomyelitis and calf compartment syndrome occurred. The wounds of 81 cases were healed at the first period,deep wound infection occurred in 2 cases. According to the function Johner-Wruhs evaluation criteria:the result was excellent in 52 cases, good in 37 cases, fair in 5 cases.

CONCLUSIONClosed manipulative or Kirschner-wire poking reduction and half circle groove external fixation can reduce the infection rate of open tibiofibula fractures. For open tibiofibula comminuted fractures, after the half circle groove external fixation for 3 to 6 weeks, a middle Kirschner-wire was removed according to fracture end healing situation to make fixation dynamic and promote fracture healing.

Objective To study the effects of hyperbaric oxygen on the diastolic heart failure in hypertensive patients. Methods 60 hypertensive patients with diastolic heart failure were randomly divided into treatment group and control group. Conventional therapies were given to patients of both groups. In addition, hyperbaric oxygen therapy was applied to those of treatment group. After 3 months, Doppler ultrasound recordings were obtained from all patients to determine the left ventricular diastolic function. Results The indexes of left ventricular diastolic function were im-proved after treatment in both groups(P < 0.01) ,and treatment group was better than control group(P < 0. 05). Conclusion For hypertensive patients with diastolic heart failure, hyperbaric oxygen can improve heart diastolic function.

Objective To investigate the differentiation of neuroendocrine component (NEC) in colorectal adenocarcinoma in relation to its significance by comparing the outcome between patients with or without NEC.Methods The paraffin sections from patients with pathologically confirmed colorectal adenocarcinoma were retrospectively collected and screened for those with NEC by morphological examination and immunohistochemistry with neuroendocrine markers.Control patients (n=54) without NEC were selected from colorectal cancer database and 2: 1 matched on the basis of clinical features with NEC positive patients (n=27).Relative analysis was performed between two groups.Results With a median follow-up of 72 months,the 5-year disease free survival was 58.0% (16/27) in NEC positive group and 79.1% (43/54) in control group (P=0.036).Similarly,the 5-year cancer-specific overall survival was significantly lower in NEC positive group than in control group (58.3% versus 81.1%,P=0.037).Cox regression showed that the 5-year cumulative risks of disease recurrence and cancer-caused death in NEC positive patients were 2.38 and 2.41 times higher than those in control patients,respectively.Conclusions NEC appears to bear a poor prognosis in patients with colorectal adenocarcinoma.

Objective To report our self-designed guide module for placement of posterior column lag screws in anterior-posterior column acetabular plate using CT reconstruction data.Methods The CT scan data of 50 normal adult pelves were collected from February 2012 to April 2013,involving 30 males and 20 females with an average age of 46.4 years(range,from 25 to 69 years).The data were imported into Mimics 10.01 software for reconstruction of semi-pelvic models.Virtual cylindrical implants were placed intraosseously in both the left and the right posterior columns.The perpendicular distance (OP) from the insertion point O of the virtual cylindrical implant to the arcuate margin (P) and the distance (PI) from the point P to the point I,the crosspoint of the extension line of the ischial ramus and the arcuate margin were measured respectively.The angle (∠φ) between the direction of screws and the plane of guide module and the angle (∠θ) between the direction of screws and the long axis of guide module were also measured respectively.Results The average length of PI was 0.98 ± 0.13 cm,with 1.08 ± 0.22 cm in females and 0.95 ± 0.27 cm in males.The difference between genders was not statistically significant (P ＞ 0.05).The average length of OP was 1.09 ± 0.26 cm,with 1.06 ± 0.29 cm in females and 1.12 ± 0.24 cm in males.The gender difference was not statistically significant either (P ＞ 0.05).The mean value of ∠ φ was 55.43° ± 3.64°,with 55.33° ± 4.00° in females and 55.50° ±3.43° in males.The difference between genders was not statistically significant (P ＞ 0.05).The ∠θ value in females was 39.21 ° ± 2.45° and 35.58° ± 2.31 ° in males.The gender difference was statistically significant (P ＜ 0.05).Conclusions In design of the guide module,the nail holes should be located about 1 cm away from both the posterior edge and the medial edge,the angle between the screw direction and the module plane should be approximately 39° in females and 35° in males,and the angle between the screw direction and the long axis of the module approximately 55°.
