BACKGROUND:Now the filling material which is used for the treatment of osteoporotic compression fractures is mainly polymethacrylic acid (PMMA),but the PMMA as a permanent foreign body cannot promote bone regeneration,and has a downward extension of the possibility of mechanical properties with time prolonging,so a new type of filling material used to substitute PMMA is looking.OBJECTIVE:To investigate the effect and image characteristics of different filling materials on percutaneous vertebroplasty performing on a goat model of osteoporotic compression fracture.METHODS:Three vertebral fracture models were established on osteoporosis goats by using an appropriate mechanical stress.Under the G-arm X-ray machine,the fractured vertebrae was performed with percutaneous vertebroplasty and then filled with polymethyl methacrylate (PMMA),self-setting calcium phosphate cement (CPC) and recombinant human bone morphogenetic protein-2(rhBMP-2)/self-calcium phosphate cement.RESULTS AND CONCLUSION:① A total of 36 vertebral bodies of 12 goats were successfully performed with percutaneous vertebroplasty,and there was no significant difference in filling quantity among three materials (3.5±1.8) mL (P>0.05).Bolus resistance of PMMA was strong,but operative time was short,and the image was great;the bolus resistance of self-CPC and rhBMP-2/self-CPC was weak,operative time was long,but there was no leakage placeholde.②CT scanning results on the 2~(nd) day after surgery demonstrated that the three materials were disorderly distributed in the vertebral body,showing high-density patching shaping.Six out of 36 vertebral bodies were leakage,which was induced by PMMA (n=4),self-CPC (n=1),and rhBMP-2/self-CPC (n=1).③ Scanning electron microscope indicated that all materials in the PMMA group were not able to closely bind with host bone,but self-CPC and rhBMP-2/self-CPC were able to closely bind with host bone.The results suggested that rhBMP-2/self-CPC is characterized by long-term operation,short time of bone substitute,and stabilization of reconstructed spine.

[ Objective ] To investigate the relationship between tongue manifestations and immune function in chronic hepatitis B with HBsAg, HBeAg and HBcAb positive. [Methods] Among the cases of HBsAg, HBeAg and HBcAb positive from the out - patient department and health screening survey, 200 chronic hepatitis patients and 100 asymptomatic HBV carriers with glumatic - pyruvic transaminase at normal level were included. Thirty healthy volunteers served as control. Relationship of tongue manifestations with phytohemagglutinin (PHA) skin test and the serum levels of immunoglobulin (Ig) G, IgA and IgM was analyzed. [Results] With the development of chronic hepatitis, the immune function became disordered and tongue manifestations abnormal. Reddish tongue with or without yellowish greasy fur or yellowish fur showed the hyperactivity of immune function; whitish swollen tongue with or without whitish greasy fur indicated the hypoactivity of immune function; dull purplish tongue was the sign of disordered immune function. The shape and color of tongue was superior to tongue fur in showing the condition of immune function ( P

ObjectiveTo investigate the characteristics of left ventricular structural damage in patients with primary aldosteronism(PA).MethodsA total of 438 inpatients with hypertension from January 2007 to June 2010 were screened for PA,and diagnosis was made in 213 PA patients and 225 patients with essential hypertension (EH).The left ventricular structure of all subjects was evaluated according to the results of echocardiographic measurements.Results The duration of hypertension and plasma aldosterone level in patients with PA were significantly higher (P＜ 0.01 ),while the serum potassium and plasma renin activity were significantly lower (P＜0.01 ) than those in patients with EH.The interventricular septum thickness,left ventricular end-diastolic dimension,left ventricular mass index (LVMI),left ventricular end-diastolic volume,and stroke volume in patients with PA were significantly higher than those in EH patients( P＜0.01 ) after the duration of hypertension was corrected.In patients with PA,the prevalence of left ventricular hypertrophy (LVH) was higher than that in EH patients ( 53.1％ vs 33.8 ％,x2 =16.57,P ＜ 0.01 ). Normal left ventricular geometry ( NG ),concentric remodeling ( CCR ),concentric hypertrophy( CCH),and eccentric hypertrophy (ECH) were found respectively in 24.9％,22.1％,22.1％,and 30.9％ of patients with PA.Multiple stepwise regression analysis showed that the seated plasma aldosterone level (β=0.43,P ＜ 0.01 ) and systolic blood pressure (β =0.45,P ＜ 0.01 ) were the main factors that influenced LVMI.The course was the main parameter that influenced relative wall thickness(β=0.011,P＜0.05 ).Conclusion The prevalence of LVH is higher in patients with PA than that in EH patients.The eccentric hypertrophy is the most common left ventricular geometrical pattern in patients with PA.

Objective To compare the short-term efficacy and main side effects between one-week and two-week schedule of cetuximab plus chemotherapy for metastatic colorectal cancer. Methods 56 patients with metastatic colorectal cancer were enrolled, ECOG physical status 0～2, good liver and renal function, using the RECIST published in 2000 to evaluate the measurable lesions. 30 patients received oneweek schedule of cetuximab plus chemotherapy, cetuximab was administered at an initial dose of 400 mg/m~2 followed by weekly doses of 250 mg/m~2; 26 patients received two -week schedule of cetuximab plus chemotheraphy, cetuximab was administered at an initial dose of 500 mg/m~2 and the same dose was given every two weeks. The termination of the study was patients finishing 8 weeks treatment or disease progress.Results 28 patients were evaluable in one-week schedule group: CR 1, PR 7, SD 11, PD 9, RR was 28.6 %,DCR was 67.9 %. 26 patients were evaluable in two-week schedule: none of CR, PR 8, SD 9, PD 9, RR was 30.8 %, DCR was 65.4 %, and no significant difference was found(P >0.05). Grade Ⅲ-Ⅳ toxicity were rash,nausea, vomiting, neutropenia and reduction of leukemia, no significant difference was found in the two groups (P >0.05). Conclusion The therapeutic effect and safety for metastatic colorectal cancer are similar between one-week and two-week schedule of cetuximab plus chemotherapy.

Objective To evaluate the diagnosis and application values of endoscopic ultrasonography (EUS) with micro-probe in duodenal lesions.Methods Clinical data of 37 patients with duodenal lesions and underwent EUS with micro-probe were analyzed retrospectively.All lesions were treated with endoscopic mucosal resection or surgical resection to get the pathological diagnosis.The diagnostic accuracy of EUS with microprobe and endoscopic biopsy was analyzed respectively.Results The overall diagnosis accuracy of EUS with micro-probe on duodenal lesions was 78.38％ (29/37),with a higher diagnostic rate in duodenal lipoma 4/4and duodenal adenomas 10/12 than in early duodenal cancer 2/4 or inflammatory hyperplasia 3/8.The overall diagnostic accuracy of biopsy on duodenal lesions was 40.54％ (15/37),with a higher diagnosis rate on duodenal carcinoid 1/1 and adenoma 7/12 than on duodenal stromal tumor 1/10 and lipoma 1/4.Conclusion Pathological evaluation of endoscopic biopsy sample is not a golden standard for the diagnosis of duodenal lesions,while EUS with micro-probe has better diagnostic and application value.

Objective To determine the feasibility and safety of transprostatic utricle seminal vesiculoscopy in the treatment of hemospermia. Methods Totally 11 patients with hemospermia, mean age of (46.6 ± 3.5) years, ranging from 38 to 68 years, for 3 months admitted from September 2012 to August 2015 were enrolled, Their main manifestations were hemospermia. Painful ejaculation was observed in 7 patients, and perineal and testicular pain occured in 4 patients. They all underwent transprostatic utricle seminal vesiculoscopy, and then were followed up for 3 to 6 months. Results Ten patients were operated successfully, but 1 patient failed. The operation revealed that the causes of hemospermia were seminal vesiculitis in 8 cases, seminal vesiculitis accompanied with seminal calculi in 2 cases, and ejaculatory duct cyst in 1 case. Operation time was (29.2 ± 3.2) min ( ranging from 25 to 37 min) , and hospital stay was 2 d ( from 2 to 4 d). Hemospermia disappeared in 10 patients within 1 month of surgery, and hemospermia recurrence was observed in 1 patient within 6 months. The patient was treated with transprostatic utricle Holmium laser incision, then hemospermia was dispeared,Two cases of postoperative epididymitis were cured after one week of antibiotic treatment. Conclusions Seminal vesiculoscopy is a safe and effective to treat hemaospermia.
