Objective To evaluate the clinical and imaging characteristics of osteoid osteoma in femoral neck and to improve diagnostic accuracy of this disease.Methods Twenty-one patients (18 males and 3 females,age,7-26 years,median age,13 years) with pathologically proven osteoid osteoma of the femoral neck were retrospectively analyzed for their clinical profile and radiologic features.CT and X-ray examinations were performed in all patients,10 of them pefformed post-contrast CT scan and 4 of them performed MRI examinations.Results Nineteen patients had hip pain (pain worse at night in 11,and 8 received salicylates treatment with good response),and 2 patients only with intermittent claudication.The duration ranged from 2 months to 54 months (median duration 12 months).X-ray: Nidus was seen on plain film in 10 cases,18 cases showed different degrees of bone sclerosis of the nidus.CT: Nidus was demonstrated in all cases.Among them,8 were intracortical,6 were subperiosteal,7 were endosteal.Twenty cases showed different degrees of bone sclerosis of the nidus-extra-articular anteromedial cortical surface of the femur neck.Nineteen cases showed vascular groove sign.MRI: Nidus was seen in 4 cases.Bone sclerosis was low signal on all sequences.Three cases had joint effusion,4 cases had bone marrow edema,and 2 cases had synovial thickening.Conclusions Although osteoid osteoma of femoral neck has non-specific clinical features,the radiographic findings are usually typical.The nidus of osteoid osteoma is often located within the joint.Bony sclerosis occurs at the area of extra-articular anteromedial cortical surface of the femur neck.CT examination remains an optimal method to identify the nidus.

Objective To evaluate the orthodontic effect of surgery on mixed dentition period class Ⅲ malocclusion and to investigate the effective therapeutic method of the skeletal class Ⅲ malocclusion.Methods A total of 20 patients aged 8.5 to 9.1 years with early mixed dentition class Ⅲ skeletal malocclusion.The treatment was divided into two phases.During the first phase,the entire stuffy group was treated with a bonded maxillary expansion and protraction.During the second phase,the entire study group received multiple loop edgewise arch wire (MEAW) treatment until an ideal occlusion relationship achieved.Comparison of the pre-and post-orthodontic treatment cephalometric radiographs had been done after maxillary protraction and MEAW were applied for patients.Results In the 20 patients after orthodontic treatment,Class Ⅲ skeletal facial profile was improved,the retraction of anterior teeth was obvious,and there were significant changes in dentition; the profile of soft tissue and satisfactory occlusion relationship were significantly improved,as compared with the changes between pre-treatment and post-treatment.Conclusions Skeletal Ⅲ malocclusion in early mixed dentition can be successfully treated.The results can be satisfied with improved class Ⅲ skeletal and molar relationship,high-angle and profile of soft tissue.

BACKGROUND:Anterior cervical discectomy and fusion surgery is a good choice for repair of degenerative cervical disc herniation, but it is reported that fusion can affect the exercise of cervical neighboring stages. Artificial disc replacement can not only play a role in mitigation of cervical disease neurological symptoms and signs, but also maintain stability and semental activity of cervical spine, and reduce secondary adjacent segmental degeneration.
These two methods which applied in cervical degenerative intervertebral disc herniation stil remain controversial. OBJECTIVE:To investigate the short-term effect of artificial cervical disc replacement and anterior cervical decompression and fusion for the treatment of single segmental cervical disc herniation. METHODS:Total y 48 patients with single segment radiculopathy or myelopathy cervical diseases induced by cervical disc herniation that required surgery and received a three-month fol ow-up were included and retrospectively analyzed. These patients were divided into replacement group (n=21) and fusion group (n=27) according to the different repair programs. Patients in the replacement group were subjected to Prestige LP cervical artificial disc replacement, and patients in the fusion group were subjected to disc fusion using interbody fusion cage of Johnson or al ogeneic fibularing. They were fol owed up at 1 week, 3, 6, 12, 24, 36 months after treatment. Complications were recorded during the fol ow-up. The pain of patients was evaluated using neck and upper limb pain visual analogue scale scores. The therapeutic effect was evaluated using Japanese Orthopaedic Association (JOA) score. The clinical symptoms improvement and daily functional status of patients after treatment were evaluated using cervical disability index. RESULTS AND CONCLUSION:During the final fol ow-up, the fusion rate in fusion group was 93%(25/27). Comparisons between groups:at the 1 week and final fol ow-up after treatment, the visual analog scale scores of neck and upper limbs and cervical dysfunction indexes were al lower than those before treatment;the Japanese Orthopaedic Association scores were higher than those before treatment (P<0.05). In the final fol ow-up, the visual analog scale scores of neck and upper limbs and cervical dysfunction index were al lower than those after one week of treatment, and the Japanese Orthopaedic Association scores were higher than those after one week of treatment (P<0.05). There were no significant differences in the above indicators at each time point between these two groups (P>0.05). The cervical activity and surgical segmental motion after cervical disc replacement were significantly higher than those in the fusion group;the difference was statistical y significant (P<0.05). There were no serious complications in these two groups. There was no significant difference in the incidence of complications between these two groups (P>0.05). These results suggest that the artificial cervical disc replacement and anterior cervical decompression and fusion for the treatment of single cervical disc herniation have the same effect in terms of patients’ symptoms mitigation. With respect to fusion technique, artificial disc replacement surgery has the advantage of maintaining cervical stability and activities of replacement segments.

ObjectiveTo evaluate the application of 18fluoro-deoxyglucose positron emission tomography (FDG-PET) to the staging and predicting outcome in patients with lymphoma.Methods 41 patients with newly diagnosed lymphoma(median age 57 years)were explored with FDG-PET prior to and after 4 cycles of chemotherapy.With a median follow-up of 30 months (range 10-68 months),the value of FDG-PET to staging and predicting clinical outcome was assessed. Results The maximum standardized uptake value (SUVmax) of nodal and extranodal lesions was 9.7±6.9 and 8.4±6.8 respectively prior to treatment.There were significant difference (P＜0.05) in aggressive non-Hodgkin's lymphoma and indolent non-Hodgkin's lymphoma,no significant difference(P＞0.05)in non-Hodgkin's lymphoma and Hodgkin's lymphoma(HL), B-cell neoplasms and T-cell neoplasms,germinal center B-cell-like DLBCL and activated B-cell-like DLBCL. In 41 patients, 22 patients (54 ％)were detected extranodal focus by FDG-PET before chemotherapy. FDG-PET imaging upstaged in 6(15％)of initial lymphoma patients.There were 15 patients (37 ％) in stage Ⅰ and Ⅱ and 26 patients(63 ％)in stage Ⅲ and Ⅳ by FDC-PET scan.1 patient (7 ％) in stage Ⅰ and Ⅱ,6 patient (23 ％) in stage Ⅲ and Ⅳ died of disease progression during follow-up.After 4 cycles of chemotherapy,the FDG-PET was negative in 41％(17/41),positive in 59 ％(24/41) respectively.1 patient(6 ％)died of disease relapse among 17 patients who were FDG-PET negative, 6 patient (25 ％)died of disease progression among 24 patients who were FDG-PET positive during follow-up. Conclusion FDG-PET scanning plays an important role in the pretreatment staging and prediction of the prognosis after 4 cycles of chemotherapy in patients with lymphoma.Thus it may offer the potential for change in treatment paradigms.

Objective: To explore the clinical response on cardiac resynchronization therapy (CRT) in patients of chronic heart failure (CHF) with different QRS wave morphology. Methods: A total of 52 CHF patients received CRT in our hospital and the Seventh People's Hospital of Zhengzhou City from 2010-03 to 2013-07 were retrospectively studied. The patients were divided into 3 groups: True-complete left bundle branch block (t-CLBBB) group,n=20, Classic LBBB (CLBBB) group,n=15 and IVCD group,n=17. The general clinical condition, the indexes of echocardiography at 6 months of follow-up study including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), NYHA classiifcation and 6-MWT were examined and compared among different groups. Results: In general clinical condition, the ratio of non-ischemic heart disease patients in t-CLBBB group was higher than those in CLBBB group and IVCD group, allP<0.05. By 6 months follow-up study, LVEDD in t-CLBBB group (62.6 ± 8.9) mm was lower than those in CLBBB group (70.0 ± 8.9) mm and IVCD group (72.8 ± 8.0) mm, LVEF was higher in t-CLBBB group (38.5 ± 6.2) % than those in CLBBB group (31.7 ± 6.7) % and IVCD group (30.1 ± 6.7) %. NYHA classiifcation in t-CLBBB group (2.00 ± 0.45) grade was lower than those in CLBBB group (2.73 ± 0.80) grade and IVCD group (3.12 ± 0.78) grade . 6-MWT in t-CLBBB group (302.0 ± 57.9) m was longer than those in CLBBB group (257.3 ± 59.0) m and IVCD group (220.2 ± 57.9) m, allP<0.05. Conclusion: CRT is an effective method for treating CHD patients, different QRS morphology may have different response, the patients with t-CLBBB would make better response.

Objective To investigate the methylation status in the promoter region of Dickkopf-3 (Dkk3) gene in patients with myelodysplastic syndromes (MDS),and to initially explore the relationship between the methylation of this gene and survival time.Methods Methylation-specific PCR (MSP) was applied to measure the promoter methylation of Dkk3 gene in 43 bone marrow or peripheral blood samples of MDS patients.As controls,70 normal peripheral blood samples from general outpatients were examined.Results In 43 patients with MDS,7 patients (16.3 ％) showed Dkk3 gene methylation.And 5 of them were semi-methylation status,2 of them were exhaustive methylation status.In 70 controls,1 showed Dkk3 gene semi-methylation.The frequency of methylation in MDS patients was significantly higher than that of controls (x2 =8.93,P =0.005).In the Dkk3 methylation group,2/7 were from bone marrow and 5/7 were from peripheral blood.Meanwhile,2 patients were RA,1 patient was RCMD,4 patients were RAEB.There was no significant difference between the different sample source (bone marrow or peripheral blood) for the results of the methylation status (x2 =0.051,P =0.821).Either between the different sex,age,type,chromosome and WPSS score (P ＞ 0.05).The progress of disease didn't influence the methylation frequency (P ＞ 0.05).The smvival analysis showed no relationship between the methylation of this gene and smvival time.Conclusions In this MDS group,there is high level of methyl-modification in Dkk3 gene.The methylation of Dkk3 might be one of the molecular mechanisms that contribute to the progress of patients with MDS.The peripheral blood sample maybe a better substitute in detective of Dkk3 with MDS.

The control group returned for regular visits after discharge while the experiment group received the family intervention including cognitive,psychological,behavioral and environmental intervention.The two groups were compared in terms of fall rate and degree of injury.Results The incidence of falls in the experiment group was significantly lower than that of the control group,the incidence of soft tissue injury after a fall in the experiment group was significantly lower than that of the control group(both P<0.05).Conclusion Family intervention is effective in prevention of falls in elderly hypertensive patients for it may reduce the incidence of falls and the degree of fall injuries.

A management window model for patients with atrial fibrillation (AF) was established in Tilanqiao Community Health Service Center cooperated with tertiary hospitals.Patients were screened and treated in the community health service center,and a comprehensive management plan was conducted and patients were followed-up.A total of 105 patients with atrial fibrillation (97.2％) were effectively managed with an average follow-up of 10.6 months.The CHADS2 score ≥ 2 in 78 cases,including 11 cases with administration of warfarin (14.1％) and 26 cases with paroxysmal AF without transition to persistent atrial fibrillation.Compared to the data before management,the rate of taking aspirin and warfarin in managed patients was increased (all P ＜ 0.05),the international normalized ratio (INR) of patients receiving warfarin was improved (P ＜ 0.05) ; the ratio of receiving comprehensive treatment program,standardized treatment and health education were significantly increased (P ＜ 0.05) ; the awareness of the disease,treatment compliance and satisfaction of patients were improved significantly (all P ＜ 0.05).The results suggest that the management widow model is feasible and effective for management of patients with atrial fibrillation in community health service centers.

Objective: To evaluate the short-term effect of thrombus aspiration catheters combining tiroifban medication for myocardial tissue reperfusion recovery in patients with acute ST-elevation myocardial infarction (STEMI).
Methods: A total of 105 STEMI patients with percutaneous coronary intervention (PCI) in our hospital from 2011-05 to 2013-05 were studied, there were 73 male and 32 female with the mean age of (58.39 ± 10.37) years. The patients were randomly divided into 2 groups, Group A, the patients received thrombus aspiration catheters with intravenous tiroifban, n=53 and Group B, the patients received tiroifban and PCI, n=52. The basic clinical features, myocardial tissue perfusion level, major adverse cardiovascular events (MACE) at post operative and in-hospital period were recorded, the cardiac function was examined by echocardiography at 6 months after PCI in both groups.
Results: The basic clinical features were similar between 2 groups. The thrombolysis in myocardial infarction trial (TIMI) 3 lfow rate was higher in Group A than that in Group B (92.45% vs 55.77%), P=0.000. TIMI 2 and TIMI 0~1 lfow rates were lower in Group A than that in Group B (7.55%vs 26.92%), P=0.008 and (0%vs 17.31%), P=0.002. The adjusted TIMI frame was lower in Group A (27.26±5.50) vs (38.98±5.42), P<0.001. The echocardiography at 6 months after PCI indicated that Group A had higher LVEF than that in Group B (0.55±0.06) vs (0.47±0.06), P<0.001;lower left ventricular end diastolic diameter (50.77±5.45) vs (54.76±5.34), P<0.001;less angina and target vessel revascularization (16.98%vs 40.38%), P=0.008 and (9.43%vs 17.31%), P=0.008. The incidence of MI, acute heart failure, cardiac death and non-target vessel revascularization were similar between 2 groups, P>0.05.
Conclusion:Thrombus aspiration catheters combining tiroifban medication may obviously improve the myocardial tissue reperfusion and the short-term cardiac function in STEMI patients after PCI, it could reduce the incidence of no-relfow without increasing MACE.
