Objective To compare the different effects of 1% diatrizoate meglumine,2.5% mannitol and water as oral contrasts in PET/CT scan in gastrointestinal tract delineation and 18F-fluorodeoxyglucose (FDG) uptake. Methods Sixty-one patients referred for PET/CT scan without gastrointestinal diseases were divided into three groups randomly ( random number method). One liter of 1% diatrizoate meglumine,2.5% mannitol,or water was orally taken by groups 1 (25 cases),2 (20 cases) and 3 ( 16 cases),respectively before scan. The scan was performed with GE Discovery LS PET/CT scanner in two-dimensional (2D) mode 50 min after 18F-FDG (5.55 MBq/kg) injection. Patients with abdominal lesions were excluded from this study. The degree of gastrointestinal filling and 18F-FDG uptake was evaluated by 3 nuclear medicine physicians using visual analysis according to a 4-grade classification method:none,mild,moderate,and high. Statistically analysis was performed by Kruskal-Wallis,Mann-Whitney and paired t tests.Results Both the differences of serum glucose and insulin levels were not significant before and after contrast taken in group 2. Group 2 had better gastrointestinal filling than that of group 1 and also better than group 3 except in rectum. The stomach,jejunum,ascending,and transverse colon were better filled in group 1 than in group 3. The degree of 18F-FDG uptake of group 3 was significantly higher than that of group 2 in stomach,jejunum and ileum (z= -3. 192,-3.290,-3.290,all P＜0.05),and was also significantly higher than that of group 1 (z = - 3. 603,P ＜ 0.05) in jejunum. The degree of 18 F-FDG uptake of group 3 was significantly lower than that of group 1 in ascending colon (z = - 2. 706,P ＜ 0. 05 ) and was significantly lower than that of group 1 and 2 in transverse and descending colon (z= - 3. 503,- 2.403,- 4.225,-4. 027,all P ＜0.05),and was also significantly lower than that of group 2 in rectum (z = -4. 128,P ＜0. 01 ). The maximum CT values in stomach,jejunum,ileum and ascending colon in group 1 were ( 132 ±23),(191 ±31),(313 ±47) and (374±53) HU,respectively,whose difference was significant (t = -7.088--1.781,all P ＜0. 01 ). Conclusion Oral iso-osmotic mannitol intake has better gastrointestinal filling and less physiological 18F-FDG uptake compared to diatrizoate meglumine and water.

OBJECTIVETo investigate the clinical outcomes of semicircular decompression in treating old thoracolumbar fractures and intractable neuropathic pain.

METHODSFrom September 2009 to September 2013, 21 patients with old thoracolumbar fracture and intractable neuropathic pain were treated with semicircular decompression. Among initial surgery, posterior pedicle screw fixation was used in these patients, with or without laminectomy. All patients were male, range in age from 20 to 28 years old with an average of (25.00±2.38) years. Vertebral body residual bone block resulted in intra-spinal placeholder more than 50%. All patients were complete spinal cord injury (ASIA grade) or cauda equina injury. VAS scores was from 6 to 10 points with the mean of 7.14±0.91. In these patients, MRI, CT, X-rays were performed; denomination and dosage of analgesics were recorded; nerve function and pain status were respectively evaluated by ASIA grade and VAS score before and after operation.

RESULTSAll patients were followed up from 8 to 32 months with an average of (17.29±6.02) months. All bone fragments of spinal canal were removed and spinal cord decompressions were achieved. At final follow-up, VAS scores were from 0 to 8 points with an average of (2.43±2.46) points, and were obviously reduced than peroperative data (P<0.05). Eleven cases of them stopped analgesic intake and 7 cases reduced using. Three patients' symptoms and VAS scores were not improved.

CONCLUSIONOld thoracolumbar fractures and intractable neuropathic pain need receive imaging examination as soon as possible and consider semicircular decompression therapy if bone fragments were in vertebral canal and spinal canal stenosis existed. This therapy can effectively relieve pain and profit nerve functional recovery.

OBJECTIVETo evaluate the results of calcium hydroxide-based sealer Sealapex in the treatment of chronic apical periodontitis.

METHODSA total of 100 cases with chronic apical periodontitis were included and divided into two groups, calcium hydroxide sealer (Sealapex) group and ZOE sealer group, and Sealapex and ZOE sealer were respectively used. All cases were followed up for two years after treatment and the clinical results compared between the two groups. The evaluation was based on clinical examination and radiographic assessment using periapical index (PAI) and digital subtraction radiography (DSR) technique.

RESULTSThere was no significant difference between the ZOE group and Sealapex group in overall healing rates and mean quantitative analysis at 3 months and 2 years after treatment (P = 0.206, 0.776). A correlation was found between PAI and DSR (P < 0.01, gamma = 0.58).

CONCLUSIONSSealapex sealer could obtain satisfactory effects for the treatment of chronic apical periodontitis. The combination of DSR and PAI methods was able to monitor the radiographic bone changes of periapical disease.

0.05).However,the shorter the history of the disease,the better the efficacy of the treatment.The younger the patient was,the better the efficacy of the treatment.Conclusions Vulva dystrophy can be treated with focused ultrasound effectively and safely.This approach appears to be a new promising treatment method.

Objective To investigate the correlation between residual strength of neck and shoulder muscles and respiratory function in patients with cervical spinal cord injury.Methods From January,2015 to June,2016,the muscle strength of sternocleidomastoid,trapezius and deltoid was tested in 30 patients with cervical spinal cord injury five and 24 weeks after injury.Meanwhile,their neurological and pul-monary function was evaluated.Results There was correlation between the vital capacity and muscle strength of deltoid both five and 24 weeks after injury(r>0.806,P<0.05)in the patients intermittent without ventilation,and it was found in sense score five weeks after injury (r=0.914,P<0.01),motor score(r=0.979,P<0.001)and the muscle strength of trapezius(r=0.894,P<0.01)24 weeks after injury.Conclu-sion The residual strength of neck and shoulder muscles,especially of deltoid,plays an important role in the respiratory function in patients with cervical spinal cord injury.

OBJECTIVETo define the clinical features of postoperative chylothorax for lung cancer (PCLC), and to compare them with those for esophageal cancer (PCEC).

METHODWe retrospectively analysed clinical characteristics of 12 patients with chylothorax among 4 084 patients receiving resection of lung cancer, as well as 52 in 4 479 patients having resection of esophageal cancer since 1985 at our hospital.

RESULTSThe incidence of PCLC was 0.29% and that of PCEC was 1.16%. The percentage of diagnosis confirmed within 4 postoperative days was 33.3% for PCLC, and 76.9% for PCEC. The rate of typical chylous pleural effusion was 83.3% for PCLC, and 5.8% for PCEC. Symptoms and signs of PCLC were much milder than those of PCEC. The re-operation rate was 16.7% for PCLC, and 96.2% for PCEC. All patients were discharged uneventfully.

CONCLUSIONThe incidence, causes, clinical manifestations, diagnosis, and treatment of PCLC is different from those of PCEC.

BACKGROUNDIt is a surgical dilemma when patients present with both severe heart disease and neoplasms. The best surgical treatment remains controversial. This study aimed to analyze the early and long-term results of simultaneous surgical treatment of severe heart disease and neoplasms.

METHODSWe reviewed the clinical records of 15 patients who underwent simultaneous neoplastic resection and cardiac surgery between September 2006 and January 2011. There were 5 male and 10 female patients. The mean age was (59.2 ± 12.5) years and the mean left ventricular ejection fraction was (57.4 ± 11.0)%. All patients were followed up completely for a period of 12 to 51 months (mean, (33.1 ± 11.2) months).

RESULTSFifteen patients underwent simultaneous cardiac surgery and neoplastic resection. Cardiac procedures consisted of off pump coronary artery bypass grafting (n = 7), aortic valve replacement (n = 3), mitral valve replacement (n = 3), mitral valve replacement with coronary artery bypass grafting (n = 1) and left atrial myxoma resection (n = 1). Neoplastic resection consisted of lung cancer resection (n = 5), colonic cancer resection (n = 3), gallbladder resection (n = 1), colonic cancer resection with gallbladder resection (n = 1), hysterectomy (n = 2), hysterectomy with bilateral salpingo-oophorectomy (n = 2) and left ovariectomy (n = 1). Pathological examination confirmed malignant disease in 10 patients and benign disease in 5 patients. There were no perioperative myocardial infarctions, stroke, pericardial tamponade, renal failure or hospital deaths. The most frequent complications were atrial fibrillation (33.3%), pneumonia (26.7%), low cardiac output syndrome (6.7%) and delayed healing of surgical wounds (6.7%). There was 1 late death 42 months after surgery for recurrent malignant disease. At 1 and 3 years, survival rates were 100% (Kaplan-Meier method).

CONCLUSIONSSimultaneous cardiac surgery and neoplastic resection was not associated with increased early or late morbidity or mortality. Cardiopulmonary bypass does not appear to adversely affect survival in patients with malignant disease. The long-term survival was determined by tumor stage.

Objective To explore the clinical value of 99Tcm-MIBI G-MPI in patients diagnosed with myocardial bridging(MB) by CTA. Methods Forty-five patients with MB and 17 normal controls diagnosed by CTA(64 slices CT) were included. All patients underwent rest 99Tcm-MIBI G-MPI and 17 MB patients and 9 normal controls also underwent stress 99Tcm-MIBI G-MPI. Myocardial ischemia, function and wall motion were assessed. G-MPI results were compared with CTA results by χ2 test, Fisher exact test and t test. Results In patients with MB, the positive rate of abnormal perfusion by gated stress 99Tcm-MIBI G-MPI was 64.7% (11/17) and 41.2% (7/17) using quantitative analysis and visual evaluation respectively; while the data were 42.2% (19/45) and 22.2% (10/45) by rest G-MPI (P=0.035). The positive rate by rest G-MPI in MB patients was significant different among mural coronary arteries of different depths and different locations. By quantitative analysis of the stress G-MPI, the reversible, fixed, and mixed ischemia patients were 4 (35.3%), 6 (23.5%) and 1 (5.9%) respectively; the reversed, reversible and fixed abnormity of wall motion was found in 4 (23.5%), 4 (23.5%) and 2 (11.8%) patients respectively; the reversed, reversible and fixed wall thickening were found in 6 (35.3%), 5 (29.4%) and 1 (5.9%) patients respectively. There was no significant difference in left ventricular ejection fraction and peak filling rate between MB patients and normal controls in both rest and stress studies (t: from -0.564 to 1.292, all P>0.05). Conclusion The G-MPI may be useful for the evaluation of myocardial ischemia and myocardial function simultaneously in patients with MB.
