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.

Objective To present a method to treat soft tissue defects with bone exposure after the distal tihial fracture.Methods Twenty-six patients who had suffered from the distal tibial fracture complications leading to exposure of the bone or fixation material sought medical help in our department.The internal fixation material was removed and radical revision of dead and infected tissue was carried out in all cases.Five of the 26 cases were treated using a free microvascular muscle flap and the mesh skin graft by one stage.Twenty-one of them were re- paired with the same method by two-stage.Results Follow-ups were 10 to 24 months.The microvascular re- construction was successful in 22 patients.Two of the 26 cases had partial necroses of the skin graft,and the other two cases had delayed wound healing.All the fractures united.Conclusion Microvascular free muscle flap re- construction of the leg is regarded as a reliable method to treat legs with massive soft-tissue defects or defects with bone exposure and chronic infection or fistulation at the distal leg.

Objective To explore the clinical features and surgical management of aged patients with acute cholecystitis,and try to command the opportunity and procedure of laparoseopic cholecystectomy(LC)better.Meth- ods Clinical data of 52 aged cases with acute cholecystits undergone LC were analyzed retrospectively.Results All of the patients(within 48h of the acute attack)were successfully recovered without serious operative complications. Conclusion Aged acute cholecystitis progressed rapidly and its operative difficulty and risk were higher;only if more attention was paid to perioperative managements and operative time and technical skill were mastered,early LC for the patients was safe and feasible.Therefore.it should be recommended in the great majority of cases except the des- perate patients whose general condition was too poor to operate.

Objective To study the inhibitory effects of total flavonoids of scutellaria baicalensis georgi(TFSB) on S180,Hep-A-22 and Bcap-37 tumor cell proliferation in vitro and on S180,Hep-A-22 in mice bearing tumor in vivo.Methods In vitro,S180,Hep-A-22 and Bcap-37 cells were divided into control group and TFSB groups(12.5,25.0,50.0,100.0 mg?L-1).The inhibitory effects of TFSB on proliferation of S180 and Hep-A-22 were measured by XTT colorimetric assay,and Bcap-37 cells were measured by MTT colorimetric assay.In vivo,the mice bearing tumor were divided into control group,CTX group(30 mg?kg-1),high,middle,low doses TFSB groups(200,100,50 mg?kg-1).After the mice bearing S180 and Hep-A-22 tumor cells were treated with TFSB for 15 d,the tumor weights were measured,the inhibitory rates of S180 and Hep-A-22 were calculated and survival of Hep-A22 was measured after administration of TFSB for 10 d.Results TFSB inhibited the proliferation of S180,Hep-A-22 and Bcap-37 cells,IC50 values were 16.04,17.74 and 9.05 mg?L-1,respectively.The tumor weight of mice bearing S180 and Hep-A-22 cells in TFSB groups(200,100,50mg?kg-1) were lowered than that in control(P

Objective To evaluate the efficacy of pulmonary thromboendarterectomy (PTE) in treatment of chronic thromboembolic pulmonary hypertension (CTEPH) using 99Tcm-macroaggregated albumin (99 Tcm-MAA) pulmonary perfusion tomography.Methods Sixteen patients with CTEPH underwent 99Tcm-MAA pulmonary perfusion tomography before and 6-12 months after PTE.The perfusion defects and improvement both in pulmonary lobe and segment were observed pre-and post-PTE.Percentage of perfusion defect scores (PPDs％) were calculated and the change of systolic pulmonary artery pressure (SPAP) measured by echocardiography was also recorded.Results The postoperative SPAP was significantly lower than that before surgery ([36.56±8.47] mmHg vs [90.52±14.55] mmHg,t=14.14,P＜0.001).Before PTE,perfusion abnormalities were identified in 86 (86/96,89.58％) pulmonary lobes of 16 patients.In all of the 86 abnormal lobes,21 (21/86,24.42％) became normal,and the remaining 65 (65/86,75.58％) were improved after PTE.Perfusion defects were confirmed in 230 (230/304,75.66％) pulmonary segments of 16 patients before surgery.In all of the 230 abnormal segments,73 (73/230,31.74％) became normal,74 (74/230,32.17％) were improved and 83 (83/230,36.09％) remained unchanged after PTE.The mean PPDs％ decreased from (56.79±14.54)％ pre PTE to (28.20±15.24)％ at 6 12 months after PTE.The PPDs％ was positively correlated with homochronous SPAP (r=0.68,P＜0.001).Conclusion PTE can significantly reduce SPAP and improve the pulmonary perfusion in CTEPH patients.Pulmonary perfusion imaging can evaluate the curative effect of PTE.

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.
