Trichomonas vaginalis parasitizes in human genitourinary tract.The protozoon adhering to target cell plays a critical role in its contact-dependent cytotoxicity.The enzymes synthesized by T.vaginalis can hurt vaginalis epithelial cells(VECs)directly.The focal immune reaction in the location parasitized by the parasite may provide an immunologic protection.Meanwhile,inflammatory factors and immune cells may aggravate the situation.In general,the T.vaginalis-induced contact-dependent cytotoxicity is a result of the involvement of some molecular and chemical factors.

BACKGROUND: Differences of thick and thin tissues in imaging areas is great because of postero-anterior images in cervical spine-thoracic spine.Although there are many image processing functions in direct digital radiography(DR)image with big range dynamic exposing,but routine direct DR hardly reveals anatomic structure of cervical spine-thoracic spine to detect diseases.Image quality of cervical spine-thoracic spine requires improvement.OBJECTIVE: To evaluate the difference between direct DR image with tissue equalization(TE)technique and standard DR in cervical spine-thoracic spine,so as to explore the best image quality in cervical spine-thoracic spine.METHODS: A total of 200 cases were randomly selected from DR cervical thoracic image from Department of Radiology,General Hospital of Chinese PLA between April 2005 and August 2009 to evaluate the difference between these images of DR processed by tissue equalization and that of standard DR.RESULTS AND CONCLUSION: The detail images of DR with tissue equalization in different thickness area of body could be revealed clearly in the same image,while the detail images of standard DR in cervical thoracic could be revealed clearly by adjusting window width and location repeatedly.Results show that the image quality of TE technique of direct digital X-ray radiography in cervical spine-thoracic spine could be clearly improved,it could be easily read and avoid the influence of body thickness area.Moreover,it could reveal clearly other part of body in detail.DR image with TE technique in cervical spine-thoracic spine can be applied widely due to simple operation,high diagnosis rate and low cost.

OBJECTIVETo discuss the curative effect of traditional treatment and combination therapy for senile hip fracture.

METHODSUsing prospective methods to choose 300 cases of elderly patients with hip fractures from February 2011 to December 2012, which were randomly divided into comprehensive treatment group and conventional treatment group. After screening, 148 case were in comprehensive treatment group,including 62 males and 86 females with an average age of (78.76 +/- 7.32) years old ranging from 60 to 88; 45 cases were intertrochanteric fracture of femur, 103 cases were fracture of neck of femur; Singh index > or = IV in 74 cases, < IV in 74 cases;preoperative Harris score was 39.90 +/- 2.28. There were 146 cases in conventional treatment group,including 60 males and 86 females with an average age of (80.00 +/- 7.06) years old ranging from 66 to 96; 50 cases were intertrochanteric fracture of femur, 96 cases were fracture of neck of femur; Singh index > or = IV in 75 cases, < IV in 71 cases; preoperative Harris score was 40.10 +/- 2.81. Preoperative general situation,leaving bed time and hospital stay, the incidence of postoperative 12 weeks Singh index > or = IV and DPD/Cr value, Harris score at 12 months after operation and the incidence of fracture again of two groups were observed and compared.

RESULTSIn comprehensive treatment group 140 patients were followed up for 12 to 18 months with an anverage of 14.80 +/- 1.85. In conventional treatment group 132 patients were followed up for 12 to 14 months with an average of 12.75 +/- 0.79. There were no significant differences in age, gender, the classification of fracture, preoperative Harris hip score, preoperative Singh index > or = IV level and DPD/Cr value between the two groups (P > 0.05). Comprehensive treatment group had shorter leaving bed time and hospital stay, smaller postoperative 12 weeks DPD/Cr value and higher postoperative Harris score, higher incidence of postoperative 12 weeks Singh index > or = IV level, lower incidence of fracture again than conventional treatment group, there was statistically significant difference between two groups (P < 0.05).

CONCLUSIONFor the anti-osteoporosis effect, the comprehensive treatment group has more advantage than traditional treatment group in elderly hip fracture, which can further improve the elderly hip fracture treatment and provide the reference of evidence-based medicine cooperate with rehabilitation department.

Purpose To investigate the diagnostic value of high-resolution CT reconstruction techniques on the same slice in hypertrophy of transverse process of the fifth lumbar vertebra (HTPL5V), and to provide a basis for clinical diagnosis and treatment. Materials and Methods Twenty-two cases of clinically diagnosed HTPL5V and 20 normal adults were examined with GE LightSpeed 16-slice spiral CT (36 cases) and Philips iCT 256-slice (6 cases). L5 transverse process and the fifth lumber nerve were reconstructed and observed on the workstations. Results In 22 cases of HTPL5V, there were 26 pseudarthrosis formation and 2 sides with L5 transverse process touching the sacral ala. In 28 sides the iffth lumber nerve traveled through false foramina of the HTPL5V including 6 cases of bilateral compression and 16 cases of unilateral compression. In 21 cases, the nerve was compressed by hyperosteogeny on 27 sides (96.4%) and 1 side due to stenosis (3.6%). On 25 sides (89.3%) the compressed nerves were curved in shaper. There was bulging and/or herniated lumbar disc on 9 sides in 7 cases (32.1%). Conclusion High-resolution CT reconstruction techniques can demonstrate the iffth lumbar nerve of HTPL5V and provide evidence for clinical diagnosis and treatment.

Objective To explore the value of stress dual-phase (early and delayed phases)18 FFDG myocardial PET/CT in detection of myocardial ischemia.Methods Ten swine were prepared as ischemic models and underwent 3 imaging procedures:pre-model stress (8 swine),post-model rest (8 swine)and post-model stress dual-phase imaging (10 swine).To perform stress dual-phase imaging,the tested subjects were fasted for more than 12 h and underwent early-phase PET imaging at 50 min after the intravenous injection of 18F-FDG (5 MBq/kg) for 10 mins,and followed by a dobutamine stress test,and then delayed-phase PET imaging at 50 min after the stress test for another 10 mins.The post-model rest dual-phase imaging was performed in almost the same way except that there was no dobutamine-loading.18F-FDG uptake image was qualitatively analyzed and classified into 4 levels:1 =no uptake,2 =diffuse uptake,3 =focal uptake,4=focal on diffuse uptake.Level 1 or 2 was considered as normal.If the focal uptake (level 3 or 4)was found on anterior wall or septum,ischemia was diagnosed.x2 test was used to determine the difference of the rate of ischemic myocardium between the two phases.18F-FDG uptake ratio of the anterior wall to posterior wall (K) of the left ventricle was calculated (K1 for early phase and K2 for delayed phase).Wilcoxon rank sum test was applied to determine the difference between K1 and K2.Results CAG showed LAD stenosis ＞70％ in all swine.In pre-model stress dual-phase imaging,no ischemia was detected at two phases (8/8 for level 1 or 2,0 for level 3 or 4).There was no significant difference between K1 and K2(1.08±0.10,1.11 ±0.10; Z =-1.48,P＞0.05).In post-model rest dual-phase imaging,the rate of ischemic myocardium was not significantly different between early and delayed phases (1/8,3/8 ; x2 =0.50,P＞0.05).There was no significant difference between K1 and K2(1.47±0.28,1.28±0.40; Z=-2.02,P＞0.05).In post-model stress dual-phase imaging,the rate of ischemic myocardium between the two phases was statistically different (4/10,10/10;x2=4.17,P＜0.05),and the difference between K1 and K2 was also significant (1.55±0.32,1.86±0.39; Z=-2.49,P＜0.05).Conclusion Stress dual-phase 18F-FDG myocardial PET/CT might be useful for the diagnosis of ischemia.

Objective To examine the effects and mechanisms of simvastatin and fenofibrate, and combination of the two drugs on the expression of apolipoprotein M (apoM). Methods The male C57BL/6N mice ( n =32) were random divided into four groups, including control group (with no special treatment), statin group (with simvastatin [10mg/( kg · d) for 4 weeks], fibrate group (with fenofibrate [100mg/( kg · d) for 4 weeks] and combination group ( with simvastatin [10mg/( kg· d)] and fenofibrate [100mg/( kg · d) for 4 weeks]. The levels of apoMmRNA and protein, hepatic nuclear factor (HNF-1α)mRNA, liver X receptor-α (LXRα) mRNA in mouse liver were measured. Results Both of simvastatin and fenofibrate can increase the expression of apolipoprotein M ( 1.97 ± 0. 04,2. 02 ± 0. 02 ) and HNF-1αmRNA ( 1.74 ± 0. 05,1.71 ± 0. 04). Combination group obtained more effects than either single agent ( P ＜ 0. 05 ). Simvastatin could decrease the expression of LXRα mRNA ( 1.00 ± 0. 02 ) ( P ＜ 0. 05 ). Fenofibrate could increase the expression of LXRα mRNA(2. 80 ±0. 04) ( P ＜0. 05). No significant difference in LXRα expression was seen between combination( 1.56 ±0. 03 ) and control group( 1.53 ±0. 03 )( P ＞0. 05). Conclusions Simvastatin and fenofibrate can increase apoM expression. Treatment with combination of the two drugs is more effective, and the mechanism might be related to the regulation of HNF-1α and LXRα.

Recent epidemiologic data indicate that metfomin has an anti-tumor effect.However,the underlying anti-tumor mechanisms remain unclear.MicroRNAs (miRNAs)can exhibit pro-oncogenic or anti-oncogenic effects by regulating the differentiation and proliferation of cells.In vitro studies show that metformin can regulate the expressions of multiple miRNAs which are closely associated with tumor development,a process possibly relating to the anti-cancer roles of metformin.
