ObjectiveTo investigate advantage and disadvantage of different rehabilitation therapies used for cerebral palsy (CP) children complicated with epilepsy (EP).Methods140 CP children complicated with EP screened from 1402 CP cases, were analyzed for CP and EP types, MRI or CT, brain stem auditory evoked potentials (BAEP). All cases were treated with anti-epilepsy drugs (AEDs). Different rehabilitation therapies, including electrotherapeutic modalities, acupuncture, point injection, cerebroprotein hydrolysate injection, manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection were assessed.ResultsIn all 140 cases, a majority of EP types were myoclonic seizure and west syndrome, CP type was spasticity. Abnormality showed in MRI or CT (98%) and BAEP (90%). AEDs were effective for all 140 cases. Electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection could make EP severely, but manual therapy, functional training, Chinese herb braising therapy, cattle encephalon glycoside and ignotin injection had no adverse effects on EP cases.ConclusionThe principles of rehabilitation treatment for the CP children complicated with EP are taking AEDs early and in a long term, avoiding electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection, using manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection.

Objective:Three-dimensional (3D) ultrasound (US) is increasingly being introduced in the clinic,both for diagnostics and image guidance.Although dedicated 3D US probes exist,because of its expensive cost,3D US can also be acquired with the still frequently used two-dimensional (2D) US probes.Methods:Obtaining 3D volumes with 2D US probes is a two-step process.First,a positioning sensor must be attached to the probe for 2D image matching;second,a reconstruction of a 3D volume can be performed into a regular voxel grid.Results:This paper presents a way to realize the 3D US in irled-based Image Guided Radiotherapy using a homemade 2D US.Conclusions:The experiments demonstrate a method of saving costs and having advantages in clinic application.

The ultimate goal of post-genome research is to understand a complete set of proteins in a living organism for their expression pattern and biological function,which is called proteomics.One of the major challenges in proteome research is to study the protein-protein interactions,and the emerging bioinformatics approaches present us tremendous advantages when dealing with protein interaction networking and data analysis.Useful bioinformatics tools include protein-protein interaction network mapping,topology of the network,structure of the module and comparison of the network.The technology advancement in this field brings further understandings to the structure and function of cells at the proteome level,which may eventually lead to the discovery of new drug targets and design methods.This paper attempts to review the current researches on protein-protein interaction with an emphasis on bioinformatics intervention,and also summarizes some widely used methods for network analysis.

This study was to explore the optimal threshold of thyroid-stimulating hormone (TSH)-stimulated serum thyroglobulin (s-Tg) for patients who were to receive 18F-fluorodeoxyglucose (18F-FDG) PET/CT scan owing to clinical suspicion of differentiated thyroid cancer (DTC) recurrence but negative post-therapeutic 131I whole-body scan (131I-WBS).A total of 60 qualified patients underwent PET/CT scanning from October 2010 to July 2014.The receiver operating characteristic (ROC) curve analyses showed that s-Tg levels over 49 μg/L led to the highest diagnostic accuracy of PET/CT to detect recurrence,with a sensitivity of 89.5％ and a specificity of 90.9％.Besides,bivariate correlation analysis showed positive correlation between s-Tg levels and the maximum standardized uptake values (SUVmax) of 18F-FDG in patients with positive PET/CT scanning,suggesting a significant influence of TSH both on Tg release and uptake of 18F-FDG.So,positive PET/CT imaging is expected when patients have negative 131I-WBS but s-Tg levels over 49 μg/L.

Objective To evaluate the clinical value of 131 Ⅰ SPECT/CT in the differentiation of indeterminate 131Ⅰ uptake on planer whole body scan (WBS) for patients with DTC after 131Ⅰ treatment. Methods Fifty-six DTC patients ( male: 19, female: 37, mean age: 45 ± 15 years, ranging from 20 to 85 years) underwent 131Ⅰ treatment. 131Ⅰ WBS was performed five days after 131 Ⅰ treatment, followed by regional 131Ⅰ SPECT/CT for the indeterminate foci with abnormal uptake on 131Ⅰ WBS. The diagnostic difference of the two imaging modalities was compared by x2 test. Results There were 288 foci with abnormal uptake on 131 Ⅰ WBS, including 108 indeterminate foci (37.5%). Subsequent 131Ⅰ SPECT/CT identified 27 foci as DTC metastases (25.0%) and 71 foci as non-metastases such as benign lesions at nose, oral cavity, salivary gland, maxillary cyst, thyroid remnant, thymus, gallbladder, gastrointestinal tract, and uterus, or non-specific uptake of body contaminations (65.7%). However, the remaining 10 foci (9.3%) remained indeterminate on 131 Ⅰ SPECT/CT imaging. The diagnostic accuracy of 131 Ⅰ SPECT/CT was significantly higher than that of 131Ⅰ WBS (x2 = 102.35, P＜0. 01). Conclusion 131Ⅰ SPECT/CT could significantly improve the diagnostic accuracy for the differentiation of indeterminate foci with abnormal uptake on 131Ⅰ WBS.

Mitogen-activated protein kinases (MAPKs) signal is one of the important ways in eukaryotic cell,which adjusts and controls the structure and function of the cell. MAPKs in eukaryotes include p38, ERK, JNK and ERK5, etc. With the deepening research,we found that the activation of p38, ERK, JNK signal pathways were closely related with osteoarthritis (OA) cartilage injury. MAPKs are the key signaling systems involved in the production of matrix metalloproteinases and the regulation of cartilage cell proliferation, apoptosis and differentiation. Expecially the matrix metalloproteinases can accelerate the degradation of articular cartilage. So it has been the new spot in pathogenesis of osteoarthritis study.

OBJECTIVETo compare the therapeutic effects between anatomical locked plate combined with coracoclavicular ligament reconstruction and clavicular hook plate for treatment of distal clavicle fracture of Neer type II b.

METHODSFrom August 2010 to August 2013, 42 patients with Neer II b distal clavicle fractures were randomly divided into two groups as group A and group B. In group A, there were 22 cases including 14 males and 8 females with an average age of (44.2±11.6) years old. In group B, there were 20 cases including 11 males and 9 females with an average of (45.6±12.4) years old. The patients of group A were treated with anatomical locked plate combined with coracoclavicular ligament reconstruction,the patients of group B were treated with hook plate. All fractures were fresh, the time between injuries and operation was 24 hours to 7 days (mean,72 h). General information between the two groups was comparable before operation(P>0.05). Postoperative radiographic were followed up to observe the fracture healing,internal fixation and to measure coracoclavicular distance of two groups. Shoulder function after operation was evaluated by Constant-Murley score system.

RESULTSAll patients were followed up with an average of 16.8 months (ranging 12 to 24 months). There was no nonunion,infection and other complications between two groups. The clavicular stress fracture occurred in 1 clavicular hook patient at 6 months after the operation. According to the Constant-Murley score system, that the scores of group A were 90.6±6.2, 91.8±4.8, 94.7±3.6 and 97.8±1.2 at 1st, 3rd, 6 month and last follow-up after operation were higher than those of group B 74.8±3.4, 78.4±4.4, 82.2±2.8 and 94.6±3.6 (P 0.05). The fracture healing time of group A (21.6±2.2) weeks was shorter than that of group B (25.8±2.5) weeks (P 0.05). There were no statistically significant differences between two groups in coracoclavicular distance at last follow-up (P>0.05).

CONCLUSIONThe anatomical locked plate combined with coracoclavicular ligament reconstruction need not expose shoulder and can reduce the incidence of postoperative pain and limited activity of shoulder, with fewer complication, it is advantageous to the shoulder joint function early recovery.

Objective To investigate the present situation of water-improving defluoridation project and the distribution of water fluoride in fluorosis areas in Shandong province. Methods In 2005 - 2007, according to "The National and Shandong province Technical Scheme for Endemic Disease Control", the water-improving form,water type and the running status of defluoridation project in 17 cities of Shandong province were investigated, and the water-fluoride of the running projects were determined by F- ion selective electrode. Results A total of 5816projects were built that involved 8776 villages, 110 counties, 17 cities distributed in Shandong province. In which,the drilling of water-improving projects accounting for 94.55% (5499/5816), under-ground water type 97.73%(5684/5816);operating normally accounting for 75.91% (4415/5816), 7246 villages were supplied with the water, beneficiary population 6 946 459 people, non-normal projects accounting for 24.09%(1401/5816), including 1530 diseased villages. There were still 4415 projects running well. The projects with water fluoride lower than 1.0mg/L were 2893, accounting for 65.53% (2893/4415). The water fluoride higher than 1.0 mg/L accounted for 34.47%(1522/4415), ＞ 2.0 mg/L of 548, ＞ 4.0 mg/L of 97, and the maximum value of water fluoride was 9.71mg/L. Conclusions Nearly 1/4 of the water-improving projects in Shandong province are abnormal. The water fluoride of the project of more than 1/3 are exceeding the standard( ＞ 1.0 mg/L) in 4415 projects, and water-fluoride of 97 projects are higher than 4.0 mg/L. More measures should be taken to strengthen the supervision of the projects and monitoring of water fluoride.

ObjectiveTo find out the condition of endemic fluorosis in Liangshan and Boxing counties of Shandong province,and to provide the basis for future prevention and treatment of the disease.MethodsIn 2007 -2009,100 water facilities per year were selected in each county and the water fluoride was tested in Liangshan and Boxing counties of Shandong province.Ten households were selected and their water fluoride content was measured.Dental fluorosis prevalence and dental fluorosis index of school children aged 8 - 12 were checked in all monitored places(3 villages in each county).Meanwhile,urinary fluoride was detected in children carried dental fluorosis test.ResultsIn 2007 - 2009,the median of urinary fluoride in Liangshan county was 2.35,3.73 and 1.29 mg/L,respectively; dental fluorosis detection rate was 72.73％ (88/121),78.08％ (57/73),and 70.64％ (77/109),and the dental fluorosis index was 1.43,1.76 and 1.34.While in Boxing county,the median of urinary fluoride was 4.50,6.71 and 5.64 mg/L; dental fluorosis detection rate was 95.93％ (118/123),99.06％ (105/106),94.41％(152/161) and dental fluorosis index was 2.23,2.54 and 2.09,respectively.ConclusionsThe effect of prevention and control of endemic fluorosis in Liangshan county was better than that of Boxing county of Shandong province.Altering water source is an important measure to control endemic fluorosis.More defluoridation project should be carried out in endemic fluorosis areas.
