As the development of functional and molecular imaging,PET/CT gradually becomes one of methods in optimizing cancer radiotherapy treatment planning.Currently,numerous hospitals routinely use 18F-FDG PET/CT for the delineation of target volume in esophageal carcinoma (EC).However,the validity of 18F-FDG PET/CT in the delineation of target volume for EC is limited and needs further clinical validation.This review focuses on the value and validity of 18F-FDG PET/CT in the delineation of gross tumor target volume of EC primary lesions and regional lymph nodes.

OBJECTIVEThis study aims to test the accuracy and precision of iWitness photogrammetry for measuring the facial tissues of mannequin head.

METHODSUnder ideal circumstances, the 3D landmark coordinates were repeatedly obtained from a mannequin head using iWitness photogrammetric system with different parameters, to examine the precision of this system. The differences between the 3D data and their true distance values of mannequin head were computed.

RESULTSOperator error of 3D system in non-zoom and zoom status were 0.20 mm and 0.09 mm, and the difference was significant (P 0.05). Image captured error of 3D system was 0.283 mm, and there was no significant difference compared with the same group of images (P>0.05). Error of 3D systen with recalibration was 0.251 mm, and the difference was not statistically significant compared with image captured error (P>0.05). Good congruence was observed between means derived from the 3D photos and direct anthropometry, with difference ranging from -0.4 mm to +0.4 mm.

CONCLUSIONThis study provides further evidence of the high reliability of iWitness photogrammetry for several craniofacial measurements, including landmarks and inter-landmark distances. The evaluated system can be recommended for the evaluation and documentation of the facial surface.

Objective To evaluate the results of surgically treated Chiari Ⅰ malformation (CMI) with posterior fossa decompression and reconstruction techniques.Methods Sixty-nine patients with CMI malformation underwent posterior fossa reconstruction.The operation involes dissection soft tissue from the suboccipital region,decompression by removing the posterior rim of the foramen magnum.Then the dura was opened widely with Y shape,as it often acts as a constricting band,particularly at the level of the foramen magnum.After dissecting the subarachnoid adhesions in cisterna magna with microsurgery techniques,dissecting part of the tonsillar hernia,opening the foramen of Magendie into the 4th ventricle and closing the dura using artificial dura mater,cranial bone flaps was repositioned centrally along the inferior edge of the craniectomy defect,so as to support the dura over the cerebellar hemispheres.Results Until the final follow-up,the clinical symptoms were improved in 56 patients,3 had recurrence after 1 year postoperatived,4 had recurrenced after 2 years postoperatived,and 87.5％ patients were stable.The patients took followed-up MRI at least once form 3 months to 6 months,and 13 cases were lost.One case with tension pneumocephalus,and 5 cases with subcutaneous effusion and cerebro-spinal fluid (CSF) incision leakage.There were no death and disability.Thirty-one cases favors the development of syringomyelia,6 showed the stable of syringomyelia,and 2 had an increased size of the cavity.Conclusion Dissecting the subarachnoid adhesions in cisterna magna with microsurgery techniques,dissecting part of the tonsillar hernia,opening the foramen of Magendie into the 4th ventrica,and circulation of CSF pathway are important to improve thetherapeutic effect of CMI.It is also very important to decompression with small cranial bone flaps,closing the dura using artificial dura mater under no tension,and bone structure reconstruction in the clinical practice.

Objective: To explore early diagnostic and resent prognostic assessment value of serum levels of ischemia-modified albumin (IMA) and cardiac troponin I (cTnI) for acute coronary syndrome (ACS).Methods: A total of 175 ACS patients were selected, including 73 cases with unstable angina pectoris (UAP), 61 cases with non-ST elevation myocardial infarction (NSTEMI) and 41 cases with ST elevation myocardial infarction (STEMI).According to chest pain-to-visit time, ACS patients were divided into <3h group (n=112) and 3~6h group (n=63);another 40 healthy subjects were selected simultaneously as healthy control group.Serum IMA and cTnI levels were compared among above groups and between patients suffering from major adverse cardiovascular events (MACE) within 30d or not in <3h group.Risk factors for MACE in <3h patients within 30d were screened.Results: Compared with healthy control group and UAP group, there were significant rise in serum levels of IMA[(16.78±4.25) μg/L, (35.16±8.32) μg/L vs.(49.76±9.29) μg/L, (52.07±11.34) μg/L], cTnI[(0.17±0.06) ng/ml, (0.15±0.06) ng/ml vs.(7.65±1.29) ng/ml, (8.83±1.40) ng/ml]in NSTEMI group and STEMI group, and IMA level in STEMI group was significantly higher than that of NSTEMI group, that of UAP group was significantly higher than that of healthy control group (P<0.05 or <0.01);serum IMA level of <3h group was significantly higher than those of 3~6h group and healthy control group, and cTnI level of <3h group was significantly lower than that of 3~6h group (P<0.01 all);serum levels of cTnI and IMA in patients suffering from MACE in <3h group were significantly higher than those of patients without MACE (P<0.01 both);multi-factor Logistic regression analysis indicated that elevated serum IMA level was an independent risk factor for MACE within 30d in ACS patients[OR=2.757,95%CI(2.084~4.705), P=0.001].Conclusion: The levels of cTnI and IMA significantly rise in ACS patients.IMA level possesses early diagnosis and recent prognosis evaluation value.

Objectives: To inveatigate Helicobacter pylo r i (Hp) in dental plaque and its relevance to gastric disease.Methods: 40 physical examination subjects were recruited. Subgingival plaque and gastric biopsy samples were respectively collected for detection of Hpby in vitroculture. Results: Hpwas identified in gastric biopsy from ten of thirty-seven (27.03%) subjects with proven chronic gastric disease. From five of the ten, Hpwas isolated in their dental plaque. None of three subjects without chronic gastric disease had Hpin their gastric bi opsy. However, Hpwas found in dental plaque from one of the three.C onclusion: The results suggest that dental plaque is an ecological niche of Hp. Oral Hpmay be related to chronic gastric disease.

Objective:To observe the clinical effect of acupuncture on chronic obstructive pulmonary disease (COPD), and the improvements of patients’ pulmonary ventilation function and 6-minute walk test (6-MWT) distance. Methods:A total of 80 COPD patients [grade 3-4 in Global Initiative for Chronic Obstructive Lung Disease (GOLD), qi deficiency of the lung and kidney in traditional Chinese medicine (TCM) pattern] were randomly allocated into a treatment group (n=40) and a control group (n=40). Salmeterol Xinafoate and Fluticasone Propionate powder (Seretide,50μg/250μg) for inhalation was used for basic treatment in both groups (once in the morning and once in the evening). Patients in the treatment group received acupuncture at Feishu (BL 13), Shenshu (BL 23), Qihai (CV 6), Guanyuan (CV 4), Dingchuan (EX-B 1), Danzhong (CV 17) and Zusanli (ST 36) twice a week for 3 months. After 3 months of treatment, clinical effects, lung ventilation functions and 6-MWT distance were observed and compared in the two groups. Results:After 3 months of treatment, the total effective rate was 95.0% in the treatment group, versus 80.0% in the control group, showing a statistical difference (P<0.05); the phlegm expectoration, dyspnea and shortness of breath were more significantly improved in the treatment group than those in the control group (P<0.01,P<0.05); and the 6-MWT distance and forced expiratory volume in 1 second percentage of predicted value (FEV1%) were more significantly improved in the treatment group than those in the control group (P<0.05,P<0.01). Conclusion:Seretide inhaler combined with acupuncture can improve signs and symptoms in COPD patients, increase the 6-MWT distance, improve FEV1% and obtain better results than Seretide alone.

Objective To study the function of the nano-molecular polyamide-amine (PAMAM) as microRNA(miR) carrier targeting gastric adenocarcinoma, and the foundation of developing an efficient delivery of small molecule drugs tar-geting gastric cancer thereof. Methods The folic acid (FA)/PAMAM comoles compound was prepared by dialysis method. After transfection of miR-7 or liposomes into SGC-7901 cell line, fluorescence microscope was used to detect the gene trans-fect efficiency. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the miR-7 level. The immu-nocytochemistry assay was used to test the protein expressions of epidermal growth factor receptor (EGFR), protein kinase B (PKB) and proliferating cell nuclearantigen (PCNA). The transwell system was utilized to explore the migration ability of tu-mor cells. Results Compared with liposme, FA/PAMAN complex compound can significantly improve the level of miR-7 in SGC-7901 cells,reduce the protein levels of EGFR, PKB and PCNA in SGC-7901 cells, and also reduce the percentage of cancer cell migration (P<0.05). Conclusion PAMAM can effectively transfect miR into gastric cancer cells, which is expected to become an efficient delivery of small molecule drugs.

Objective To investigate the clinical application of 3.0 T mobile iMRI and neuronavigation in the microsurgical operation for the high grade gliomas in brain functional area.Methods The clinical data of 47 cases which were operated from April,2012 to August,2014 assisted by intraoperative magnetic resonance and neruonavigation system were analyzed retrospectively,including 19 cases of near the frontal motor areas,21 cases of closed to the dominant hemisphere language areas,and 7 cases of involved multiple lobes of the brain.The operative plans were made before the operative day using 3.0 T iMRI for T1-MPRAGE plain and enhancement magnetic resonance imaging sequence,diffusion tensor imaging (DTI) sequence and blood oxygenation level dependent functional MRI (BOLD-fMRI) sequence scanning.Before the start of operation,the margin of the tumor was marked on the scalp,and removed the tumor under the microscopy,according to the need 1-4 iMRI plain scan and enhanced scan were applied to reconstruct the real-time imaging of the residual tumors and corticospinal tract,and gained once more chances to remove the tumor repeatedly,until the tumor was removed totally,accurately and safely.Results The total resection rate increased from 63.8％ (30/47) to 95.7％ (45/47) by repeated resection,and 2 cases (4.3％ lesions) with subtotal resection.The dysfunction of motion and the language barrier got worse in 4 patients (8.5％).No cases with sever complication such as death and severe disability after operation.There were no intracranial hemorrhage,infection and other adverse events.Patients were followed up with nervous system symptoms and head MRI,the follow-up period was 3 months-2 years.Twenty-eight cases (59.6％) ob-tained good clinical efficacy;the dysfunction of motion and the language barrier got worse in 4 cases (8.5％);the symptoms and tumors recurrenced in 15 cases (31.9％).Conclusion The 3.0 T mobile iMRI system combined with functional neuronavigation can accurately display the relationships among the motor and language cortex,tumors and white matter fiber bundles real-timely.The extent of the tumor resection can be assessed accurately by real-time images provided by iMRI,and the residual tumor have chames to be resected repeatedly,until the tumors were resected totally before operation finished.The iMRI system can correct intraoperative brain shift timely.The total resection rate can be improved safely and accurately by one or more times resection.
