ABSTRACT
Objective::To observe the effect of Jianpi Qingchang decoction on hormone withdrawal in patients with hormone-dependent spleen deficiency damp-heat ulcerative colitis. Method::The 60 patients with hormone-dependent ulcerative colitis with spleen deficiency and damp-heat were selected and collected from the outpatient department and the inpatient department of Longhua Hospital, Shanghai University of Traditional Chinese Medicine(TCM) between April 1, 2012 and January 31, 2014.All of patients in two groups were treated with standard hormone reduction method. The control group was given orally Bupi Yichang pills, 6 g/time, 3 times/day, and the experimental group was given orally Jianpi Qingchang recipe, 300 mL water decoction, 1 dose/d, 2 times/d. All of the patients received continuous treatment for 3 months. After treatment, disease activity index, mucosal healing evaluation, curative effect changes of TCM syndromes and changes of inflammatory factors in the two groups were observed. Result::Compared with before treatment, the two groups of Mayo scores after treatment were significantly reduced (P<0.01), and the experimental group was reduced more significantly than the control group (P<0.01). After treatment, 66.67%of patients in experimental group were in remission, and 13.33%of patients in control group were in remission, with statistically significant differences between two groups (P<0.01). After treatment, the healing rate of the control group was 46.67%, while that of the experimental group was 70.0%, with statistically significant differences (P<0.01). After treatment, the effective rate of TCM syndromes in control group was 80.0%, while that in experimental group was 96.67%, with statistically significant differences (P<0.01). Compared with control group before treatment, the levels of IL-1 in both groups were decreased (P<0.05), while the levels of IL-6 and IL-10 were increased (P<0.05). Compared with control group after treatment, the changes in experimental group were significantly better than those in control group (P<0.05). Conclusion::Jianpi Qingchang decoction can reduce the index of disease activity in patients with hormone-dependent ulcerative colitis due to spleen deficiency and dampness-heat, promote mucosal healing and improve the curative effect of TCM symptoms, and thus is worthy of clinical promotion.

<p><b>BACKGROUND AND OBJECTIVE</b>Hypopharyngeal carcinoma has a high risk for early regional lymphatic dissemination. However, reports about regional lymph node metastases, especially retropharyngeal lymph node metastases, are rare. This research explored the spread of hypopharyngeal carcinoma, especially metastases of the retropharyngeal lymph nodes by studying computed tomography (CT) and magnetic resonance imaging (MRI) images.</p><p><b>METHODS</b>The CT/MRI images of 88 patients with pathologically confirmed hypopharyngeal carcinomas that were performed at our hospital between August 2000 and March 2009 were analyzed retrospectively. The interrelations among local stage and lymph nodes in various regions were analyzed by Chi2 test and multivariate logistical regression.</p><p><b>RESULTS</b>The rate of regional lymph node metastasis for all patients was 73.9%, and the highest rates of positive lymph nodes were at levels IIa (61.4%), IIb (44.3%), and III (37.5%). Metastases to levels I, IV, V, and VI were rare, as were retropharyngeal lymph-node metastases, which were always combined with metastases at levels II and III. Univariate analysis showed that level-IV metastases correlated to metastases at levels Ib and III; retropharyngeal lymph node metastases were correlated to level IIb and bilateral cervical lymph node metastases. Multivariate analysis showed that level-VI metastases correlated to level IV and that retropharyngeal lymph-node metastases correlated to bilateral cervical lymph node metastases.</p><p><b>CONCLUSIONS</b>Regional lymph node metastases in patients with hypopharyngeal carcinoma follow some regulations, and skip metastasis is rare. The highest rates of positive lymph nodes are at levels II and III. Bilateral lymph node metastases may be a risk factor for retropharyngeal lymph node metastases.</p>

Objective To evaluate the value of L-(methyl-11C)-labeled methionine positron emissions tomography (MET PET) and MRI in target volume delineation for postoperative radiotherapy for brain high grade glioma (HGG).Methods Thirty-seven patients with supratentorial HGG were included.Both MRI and MET PET scan were performed in the same treatment position for all patients.The consistency to determine residual tumor between MRI and MET PET was analyzed.Imaging data of MET PET and MRI were coregistered using the BrainLAB image fusion software.The extension of the volume with high uptake (VMET) on MET PET were compared quantitately with the enhancing area on MRI T1W gadolinium enhancement (VGd) and the hyperintensity area on MRI T2W (VT2).Results Both MET PET and MRI were positive for 19 patients and negative for 7 patients.The consistency between these two scans was 70.3%.MET PET was integrated with MRI in 30 patients with positive MET uptake.VMET were partially or entirely outside VGd in 29 patients and VT2 in 17 patients, whereas VGd and VT2 were partially or entirely outside VMET in all patients.The maximal distance from the margin of VMET to VGd was ≥ 2.0 cm in 50%patients and the corresponding distance of VMET to VT2 was ≥ 1.0 cm in 33% patients.Conclusions The differences are existing between MET PET and MRI in determination and identification of the location and extension of residual tumor for patients with HGG.The integration of MET PET and MRI can accurately delineate radiation target volume.
ABSTRACT
<p><b>OBJECTIVE</b>To discuss the strategy of mediastinoscopy for the evaluation of mediastinal lymph node status (metastasis or not) of non-small cell lung cancer (NSCLC) prior to surgery.</p><p><b>METHODS</b>From October 2000 to June 2007, 152 consecutive NSCLC cases pathologically proven and clinically staged I-III were enrolled in the study. Of the 152 cases, there were 118 males and 34 females. Age ranged 24-79 years old and the median age was 58. All cases underwent CT and mediastinoscopy for the evaluation of mediastinal lymph node status prior to surgery. Compared with the results of final pathology, the positive rate of mediastinoscopy and the prevalence of mediastinal lymph node metastasis were calculated in the NSCLC patients with negative mediastinal or hilar lymph nodes on CT scan (the shortest axis of mediastinal or hilar lymph nodes <1 cm). Clinical characteristics used as predictive factor including sex, age, cancer location, type of pathology, T status, cancer type (central or peripheral), size of mediastinal lymph nodes (the shortest axis <1 cm or >1 cm) on CT scan and serum CEA level were analyzed by univariate and multivariate analysis with Binary logistic regression model to identify risk factors of mediastinal metastasis.</p><p><b>RESULTS</b>The positive rate of mediastinoscopy was 11.6% (8/69) and the prevalence of mediastinal metastasis was 20.1% (14/69) in NSCLC with negative mediastinal or hilar lymph nodes on CT scan respectively. In clinical stage I (cT1-2N0M0) NSCLC the positive rate of mediastinoscopy was 11.3% (7/62), N2 accounting for 6.5% (4/62) and N3 4.8% (3/62), respectively; and the prevalence of mediastinal lymph node metastasis was 19.4% (12/62), N2 ccounting for 14.6% (9/62) and N3 4.8% (3/62), respectively. In the whole group both univariate and multivariate analysis showed that adenocarcinoma or mediastinal lymph nodes > or =1 cm in the shortest axis on CT scan was an independent risk factor to predict mediastinal lymph node metastasis. In NSCLC with negative mediastinal or hilar lymph nodes on CT scan both univariate and multivariate analysis showed that adenocarcinoma was a predictor of mediastinal lymph node metastasis. Conclusion We recommend the policy of routine mediastinoscopy in NSCLC prior to surgery if the mediastinal staging was only based on CT scan. Mediastinal lymph nodes > or =1 cm in the shortest axis on CT scan mandates preoperative mediastinoscopy. Adenocarcinoma also indicates mandatory mediastinoscopy even with negative mediastinal or hilar lymph nodes on CT scan.</p>

<p><b>OBJECTIVE</b>To evaluate the value of mediastinoscopy in preoperative staging of non-small cell lung cancer (NSCLC) based on survival analysis.</p><p><b>METHODS</b>152 cases of potentially operable NSCLC were enrolled in this study. All cases underwent CT scan and mediastinoscopy for assessment of the mediastinal lymph node status before initial treatment. The definitive treatment was decided on the basis of mediastinoscopy and the survival rate was analyzed with a median follow-up of 30.5 months. Survival analysis was conducted by comparing the lymph node status which was determined by final pathology (groups pN0, pN1, pN2, pN3), CT scan (group cN0-1, cN2-3) and mediastinoscopy (group mN0-1, mN2, mN3).</p><p><b>RESULTS</b>The 5-year survival rates in group pN0, pN1, pN2 and pN3 were 61.7%, 75.0%, 32.4% and 16.1%, respectively. Both groups pN0 and pN1 had significantly higher survival rates than those in groups pN2 and pN3 (P < 0.05). There were not significant differences between survival rates in groups cN0-1 and cN2-3 (P = 0.670), while the survival rate in group mN0-1 was significantly higher than that in groups mN2 and mN3 (P < 0.05).</p><p><b>CONCLUSION</b>Mediastinoscopy is of great value in preoperative staging of NSCLC. Not only does it detect lymph node metastasis more precisely but also better predict the prognosis than CT scan.</p>

Both the accuracy and diagnostic efficacy of mediastinoscopy were superior to CT (Pearson chi(2) test, P < 0.001; Z test of the areas under the ROC curve, P < 0.001). The complication rate of mediastinoscopy was 4.6%, and the false negative rate was 7.2%.</p><p><b>CONCLUSION</b>Mediastinoscopy is safe and effective in preoperative assessment of mediastinal lymph node status in potentially operable NSCLC, while CT alone is inadequate.</p>

<p><b>OBJECTIVE</b>To compare quantitatively the enhanced thin CT section with pathologic findings in pulmonary carcinoma, pulmonary inflammatory pseudotumor (IPT) and pulmonary tuberculoma so as to demonstrate the relation of degree of enhancement and the vascular structure within the lesion with special emphasis on pulmonary carcinoma.</p><p><b>METHODS</b>Enhanced thin CT sections were obtained in 35 cases with nodular or patchy lesions in the peripheral lung field which are difficult to differentiate clinically. There were pulmonary carcinoma 21, inflammatory pseudotumor 7 and tuberculoma 7. The number of small vessels (inner diameter 0.02 approximately 0.1 mm), relatively large vessels (inner diameter > 0.1 mm) and their vascular bed areas were analyzed by computed image analyzing system. The relation between CT average attenuation and the number of vessels or the vascular bed areas were statistically evaluated.</p><p><b>RESULTS</b>1. The differences of average attenuation in carcinoma, inflammatory pseudotumor and tuberculoma were statistically significant (P < 0.05). 2. The differences in number of small vessels, relatively large vessels and vascular bed areas among these three types of lesion were also significant (P < 0.05). 3. A positive correlation was found in the average CT affenuation of lung carcinoma and its number of small vessels and relatively large vessels and 4. A positive correlation was found between the average CT attenuation in these three lesions and the relatively large vessels, total vascular amount and vascular bed areas.</p><p><b>CONCLUSIONS</b>1. The average degree of attenuation, being divided into four degrees, is of practical value in the differentiation of lung carcinoma, inflammatory pseudotumor and tuberculoma. 2. The average CT attenuation of lung carcinoma, inflammatory pseudotumor and tuberculoma is in direct proportion to the number of vessels and vessel bed areas and 3. The characteristic CT enhancement in lung carcinoma reflexes the condition of vessels and blood supply within the tumor.</p>
