Objective To observe the clinical efficacy of Kuijiening Paste acupoint application on ulcerative colitis (UC) patients of spleen-kidney Yang deficiency type, and its effect on serum levels of IFN-γand IL-4. Methods Sixty UC patients were divided into treatment group, control group and combined treatment group, 20 cases in each group, and were given Kuijiening Paste acupoint application plus placebo, oral sulfasalazine plus comfort paste and Kuijiening Paste acupoint application plus sulfasalazine respectively for 60 days. The clinical efficacy, mucosal lesions efficacy, mucosal pathology efficacy, changes of serum IFN-γand IL-4 were observed after treatment. Results There was no significant difference in clinical efficacy, mucosal lesions efficacy and mucosal pathology efficacy among the three groups (P>0.05). After treatment, IFN-γlevels of the three groups significantly reduced, and IL-4 levels significantly increased (P<0.01). The difference between the treatment group and the control group was significant (P<0.05). The difference between the combined treatment group and the control group was significant (P<0.01). Conclusion Kuijiening Paste acupoint application combined with sulfasalazine can regulate the level of immune cytokine in UC patients of spleen-kidney Yang deficiency type, and receive good clinical efficacy.

Objective To investigate the clinical and imaging features of cerebral cortical vein thrombosis (CoVT). Methods The clinical data of 13 inpatients with CoVT were enroled from September 2010 to September 2015. The etiology, clinical symptoms, imaging features, and differential diagnosis of CoVT w ere summarized and analyzed. Results Among the patients, there w ere 7 females (53.85%) and 6 males (46.15%). Their age ranged from 18 to 59 years (mean 34.23 ±12.08). The most common clinical manifestations were headache (9 patients) and seizures (9 patients). The 13 patients had cerebral parenchymal involvement and they al received anticoagulant therapy. Conclusions The clinical symptoms of CoVT are various. Seizures and headache are the most common symptoms. Most of patients are accompanied by brain parenchymal lesions and venous sinus thrombosis. When patients have headache and seizures, and head images suggest hemorrhagic infarction, imaging examination of the improvement of the cerebral venous system thrombosis is recommended.

Objective The aim of this study was to investigate the radiation dose caused by 18 F-fluorodeoxyglucose (FDG) in PET/CT examination and to optimize the concerned radiation protection. Methods Thirty patients from our conventional PET/CT examination were simple randomly selected, and they all underwent whole body PET/CT imaging. The radioactive dose of injected 18F-FDG was recorded. The internal radiation dose was calculated and the external radiation dose from patients was measured with the 451P-DE-SI ion chamber survey meter. The staff's dose was recorded with thermoluminescent detector (TLD). All dosimetry data were processed and analyzed statistically with Excel 2003. Results The injected radioactive dose of 18F-FDG was (432.9±51.8) MBq, and effective dose equivalent received per patient was (8.23±0.99) roSy. The correlation coefficient (r) of the dose equivalent rate and distance was-0.994 by power function curve fitting, and that of dose equivalent rate and time was - 0.988 by exponential curve fitting. The staff's dose was lower than the annual dose limit. Conclusions The patient's internal radiation dose caused by 18F-FDG in PET/CT examination is low, nonetheless, the clinician should always consider optimizing and minimizing the necessary radiation received by the patients. The patients having been injected with 18F-FDG should stay in one place to decrease their radiation to the public. From the medical point of view in optimizing radiation exposure, there may still be a potential to lower the injected 18F-FDG activity.

Objective To collect data and analyze the current status and prevalence changes of Crohn's disease (CD) in mainland China in recent decades. Methods A computer-based literature search was previously performed by using 50-year (1950 to 2002) of records of CD from the Chinese Database of Biology and Medicine (CBM) (1979 to 2002) and a manual year-by-year search of the literature ( 1950 to 1978). Using similar method, descriptive epidemiological data from 2003 to 2007 were collected, analyzed and compared with previous research. Results Four hundred and seventeen relevant papers during 2003 and 2007 were collected and 62 papers were eligible for inclusion. Within 62 papers, a total of 2149 cases with CD from 2003 to 2007 have been reported nationwide, comprising 1288 male and 861 female patients, result (ie,1526 cases from 1950-2002). There were no obvious changes in incidence age (younger and middle age were main components) and sex ratio ( number of male was still larger than that of female). The extrapolated CD incidence and prevalence rates were 1.21/100 000 person ? year and 2.29/100 000, respectively, which were higher than that of year 1950-2002, 0.28/100 000 person ? year and 1.38/ 100 000, respectively. Conclusions The incidence and prevalence rates of CD have been increasing rapidly, but these rates are still lower than those in Western world.

Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

Objective:To explore the correlation among serum cardiac troponin I (cTnI),N terminal pro brain natri-uretic peptide (NT-proBNP)and main endpoint events of heart in patients with chronic stable heart failure.Meth-ods:The present study enrolled 95 patients with NYHA cardiac function class III~IV from Feb 2010 to Feb 2011.According to levels of cTnI and NT-proBNP,the patients were divided into cTnI negative group (n=60)and cTnI positive group (n=35);NT-proBNP negative group (n=40)and NT-proBNP positive group (n=55),all patients were followed up for two years,and the main endpoint events were cardiogenic sudden death and rehospitalization caused by acute aggravation of heart failure.Results:Compared with negative group,the hazard ratio (HR)of end-point events was 2.69 and confidence interval (CI)was 1.54~ 4.72,P = 0.002 in cTnI positive group;HR was 2.54 and CI was 1.35~4.78,P =0.003 in NT-proBNP positive group;further interclass crossover analysis found that,when patients'cTnI and NT-proBNP were both positive,the hazard ratio of cardiac endpoint events was the highest (HR=6.34,CI 2.26~17.9,P <0.001).Conclusion:In patients with chronic stable heart failure,serum elevated levels of cardiac troponin I and N terminal pro brain natriuretic peptide are important predictors reflecting prognosis of patients with heart failure.

Objective: To investigate the effects of estrogen (E 2) on the structure of madible and femur in ovariectomized rats. Methods: 18 femal SD rats were evenly divided into 3 groups:sham-ovariectomized rats (sham-OVX),ovariectonmized rats without E 2 treatment (osteoporosis,OP) and ovariectomized rats with E 2 treatment (E 2).In the group of E 2,E 2 at the dose of 10 ?g/kg was injected into abdominal cavity of the rats every the other 2 days.All rats were sacrificed after 6-week treatment.The madible and femur samples were analyzed by bone histomorphometry with QWin550CW system. Trabecular area (Tb.Ar,%), trabecular width (Tb.Wi,?m) and trabecular seperation (Tb.Sp,?m) were calculated.Result: Tb.Ar(%),Tb.Wi (?m) and Tb.Sp(?m) in the madibles in sham-OVX rats were 29.43?3.12,10.97?1.85 and 27.59?4.21;in OP 19.44?2.24,6.45?1.73 and 42.03?5.46;in E 2 treated 26.81?2.93,9.54?1.22 and 30.98?3.65,respectively.Those in the femus in sham-OVX rats were 24.19?5.53,56.72?10.36 and 132.41?47.69;in OP 12.54?4.32,40.71?8.65 and 208.67?65.39;in E 2 treated 20.08?4.86,51.38?9.07 and 159.42?56.34,respectively.Conclusion: The bone volume decreases more in femur than in madible after ovariectomy in rats.Treament of estrogen can inhibit bone absorbtion in mandible and femur.
