Objective To evaluate the effects of nasal non-Hodgkin′s lymphoma(N-NHL) treated with chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and autologous peripheral blood stem cell transplantation(APBSCT) combined with total body irradiation(TBI);and to analyze the impact factors of prognosis. Methods 135 patients were treated between 1980 and 2000. All were confirmed by histopathology as N-NHL, including 122 T cell in origin, 12 B cell and 1 NK cell in origin. The main radiotherapy portal was set in front of the nose with a spade-like protrusion, supplement with a portal next to the ear on one side or both sides. Combined portal in facial cervical area was first used when there was invasion of the oropharynx. The median dose to the nasal cavity was 56.0Gy with a range of 35.2 to 75.5Gy, with added 30Gy to the primary lesion in two patients. Six patients received TBI combined with APBSCT, with 8Gy in the TBI group. Chemotherapy, given before or during after radiotherapy or alone, consisted of 2-6 cycles of COP, COPP, COMP, CHOP or COBDP. Prognostic factors were analyzed with Cox model. Results The local control rate was 12%,69%,76% and 83% in chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and APBSCT combined with TBI, respectively(P=0.057).The 5-year survival rate was 9%,52%,63% and 83%,respectively(P=0.032). Multi-factor analysis showed that tumor extension and treatment methods were the most important prognostic factors besides Ann-Arbor stage, but gender, pathology, age and symptoms had little effect on prognosis .Conclusions Chemotherapy plus radiotherapy group achieves a better survival rate than radiotherapy alone. It is helpful to evaluate prognosis to make more detail subareas on basis of local extensions in Ann Arbor staging system.For some N-NHL patients with good financial condition, APBSCT combined with TBI is a good choice.

OBJECTIVETo establish a reliable model for drug screening and therapy by culturing rat femoral head and inducing cartilage degeneration quickly in vitro.

METHODSThe femoral heads from the same SD rats of two-month old were divided into control group and experimental group respectively. They were cultured with DMEM medium plus 10% fetal bovine serum or DMEM medium plus 10% fetal bovine serum plus 50 ng/ml IL-1β for three days. Femoral heads were fixed in 4% paraformaldehyde, decalcified, dehydrated, embedded in paraffin and cut into slices. Specimens were stained with Toluidine blue and Safranine O-Fast Green FCF. The protein expression levels of type II collagen, MMP13, Sox9 and ADAMTS5 were analyzed by immunofluorescence.

RESULTSBoth the Toluidine blue and Safranine O staining were pale in the margin of femoral heads which were stimulated with IL-1β for three days compared to that in control group. The Fast Green FCF staining was positive at the edge of the femoral head in experimental group, which indicated that cartilage became degenerated. The expression levels of both type H collagen and Sox9 were decreased significantly while the expression levels of MMP13 and ADAMTS5 were increased in experimental group.

CONCLUSIONThe model of cartilage degeneration is established by culturing and inducing the degeneration of the femoral heads quickly in vitro.

UNLABELLEDThe purpose of this study was to evaluate the effects of cellular immunity activation on P58(+) cells expressing killer cell inhibitory receptor (KIR) and their regulatory function on cellular immunity, and provid theoretical data for preventing graft-vers-host disease (GVHD) in stem cell transplantation therapy. The mononuclear cells from human peripheral blood were incubated with IL-2, Con A and Lipostin (LP) for 72 hours. The KIR expressing cells, P58.1(+) and P58.2(+) cells, were analyzed by flow cytometry. The results showed that the percentages of CD3(+), CD4(+), CD8(+), CD16(+)CD56(+), P58.1(+) and P58.2(+) cells were greatly increased after treated with IL-2, Con A and LP, separately or in combination, and the percentages of above cells in combined treatment groups were higher than those of single stimulated groups, especially the percentage of cells in the IL-2 + LP group was significantly higher than those in IL-2 and LP singly treated groups.

IN CONCLUSIONIL-2, Con A and LP possess the ability to induce the expression of KIR and stimulate proliferation of P58.1(+) and P58.2(+) cells while to activate the celluar immunity response, the expression of P58 gene may be regulated by the activation of cellular immunity.

BACKGROUNDIrradiation dose and volume are the major physical factors of radiation-induced lung injury. The study investigated the relationships between the irradiation dose and volume in radiation-induced lung injury by setting up a model of graded volume irradiation of the rat lung.

METHODSAnimals were randomly assigned to three groups. The ELEKTA precise 2.03 treatment plan system was applied to calculate the irradiation dose and volume. The treatment plan for the three groups was: group 1 received a "high dose to a small volume" (25% volume group) with the mean irradiation volume being 1.748 cm(3) (25% lung volume); the total dose and mean lung dose (MLD) were 4610 cGy and 2006 cGy, respectively (bilateral AP-PA fields, source to axis distance (SAD) = 100 cm, 6MVX, single irradiation); Group 2 received a "low dose to a large volume" (100% volume group) with the mean irradiation volume being 6.99 cm(3) (100% lung volume); the total dose was 1153 cGy. MLD was 2006 cGy, which was the same as that of group 1 (bilateral AP-PA fields, SAD = 100 cm, 6MVX, single irradiation); Group 3 was a control group. With the exception of receiving no irradiation, group 3 had rest steps that were the same as those of the experimental groups. After irradiation, functional, histopathological, and CT changes were compared every two weeks till the 16th week.

RESULTSFunctionally, after irradiation breath rate (BR) increases were observed in both group 1 and group 2, especially during the period of 6th - 8th weeks. The changes of BR in the 100% volume group were earlier and faster. For the 25% volume group, although pathology was more severe, hardly any obvious increase in BR was observed. Radiographic changes were observed during the early period (the 4th week) and the most obvious changes manifested during the mediated period (the 8th week). The extensiveness of high density and the decreased lung permeability were presented in the 100% volume group, and ground glass opacity and patchy consolidation were presented in the 25% volume group without pleural effusion, pleural thickening, and lung shrinking. Morphologically, the 100% volume group mainly presented signs of vascular damage, including signs of vascular wall edemas, hypertrophy, and sclerosis. The 25% volume group mainly presented with erythrocyte cell exudation, inflammation, and parenchymal damage.

CONCLUSIONSThe delivery of a small dose of radiation to a large volume is not safe. A low dose smeared out over large volumes, albeit reversible, may lead to fatal respiratory dysfunction. Damage to the lung may be more dependent on the volume of irradiation than on the radiation dose. Clinically, the safest approach is to limit both the volume of the irradiated normal lung and the amount of received radiation.

OBJECTIVETo evaluate the toxicity and efficacy of weekly chemotherapy of paclitaxel and carboplatin with concurrent three dimensional conformal radiotherapy (3D-CRT)for locally advanced non small cell lung cancer(NSCLC).

METHODSFrom July 2002 to July 2004, a non-randomized prospective study of 52 patients with locally advanced NSCLC treated with 3D-CRT and chemotherapy by paclitaxel and carboplatin were carried out. Of the 52 patients, 21 received concurrent chemoradiation with 3D-CRT and weekly paclitaxel and carboplatin (concurrent chemoradiation group), 31 received sequential chemoradiation with paclitaxel and carboplatin and 3D-CRT (sequential chemoradiation group). In the concurrent chemoradiation group, paclitaxel 40 mg/m2 was administered intravenously for 1 hour. Carboplatin of 1.5 AUC/cycle was used after administration of paclitaxel on D1, D8, D15, D29, D36 and D143. In the sequential chemoradiation group, two cycles of chemotherapy were given at two weeks before radiotherapy. Paclitaxel 150 mg/m2 and carboplatin 5 AUC/cycle were administered on D1 and D21. 3D-CRT was given at two weeks after the second cycle of chemotherapy provided that the hematological examination was normal. 3D-CRT was given at 1.8-2.0 Gy/f to a total dose of 60-66 Gy/6-8 weeks.

RESULTSAll the patients completed the trial, but 12 had prolongation of treatment time for more than 1 week due to severe leucopenia with 5 in concurrent chemoradiation group and 7 in sequential chemoradiation group. The rate of complete response (CR), partial response (PR), progress of disease (NC + PD) and overall response was 9.5% (2/21), 71.4% (15/21), 19.0% (4/21) and 81.0%, respectively, in concurrent group, versus 6.5% (2/31), 67.7% (21/31), 25.8% (8/31) and 74.2% in sequential group (CR), respectively. II-III grade of esophagitis, pneumonia and leukocytopenia observed in concurrent chemoradiation group was 61.9% (13/21), 41.9% (13/31) and 23.8% (5/21) ,versus 22.6% (7/31), 42.9 % (9/21) and 19.4% (6/31), respectively, in the sequential chemoradiation group. One of those patients in concurrent chemoradiation group had IV grade of leukocytopenia. The overall median survival time was 17.5 months with 19.0 months for concurrent chemoradiation group, 15.8 months for sequential chemoradiation group. The Overall 1-, 2-year survival rate was 72.0%, 37.0%, respectively and 1 - and 2 - year local control rate was 75.0% and 75.0%.

CONCLUSIONOur data indicate that concurrent chemoradiotherapy is safe and effective for locally advanced non small cell lung cancer. Concurrent chemoradiotherapy may be helpful in improving response and survival than sequential one, but no significant difference is observed between two groups in this series(P > 0.05). Further randomized prospective study is still needed to prove it.

OBJECTIVEThe primary goal of our study was to evaluate and predict the epidemiological trend of pneumoconiosis.

METHODSWe established a new database on new-diagnosing cases of pneumoconiosis in Nanjing during 1955-2007. The database was analyzed by using SAS9.1.3 statistical software, Data sequence was stabilized by using the process of differencing. Goodness of Fit Test verified that the residual-error sequence was white noise sequence. We determined the Autoregressive Integrated Moving Average models (ARIMA models) as an appropriate model. By Taking advantage of back-substitution model, we predicted new cases of pneumoconiosis during 2008-2012. We then compared the predicted value with the actual value to test and verify the predicting function.

RESULTSWe finally had chosen out ARIMA (2, 1, 0) models to fit the original sequence, which led to the results that the observed values are basically comparable with the predicted values. The past 5-year predicted-value was similar to the actual value. We then built a new model by new cases during 1955-2012, predicting that the trend of pneumoconiosis in the next 5 years will tend to approach plateau with approximately 10∼13 new cases per year.

CONCLUSIONARIMA models is suitable for fitting large sample series of new diagnosed pneumoconiosis over the years and for the predicting the incidence of pneumoconiosis.

Objective To evaluate the prognosis factors of carcinomatous meningitis (CM).Methods The medical records of 63 patients with CM treated in our hospital from 1998 to 2008 were retrospectively analyzed. The chief prognosis factors evaluated were gender, age, primary tumor type,Karnofsky performance status (KPS) scores, interval between diagnosis of primary tumor and CM,treatment, radiation dose and primary tumor control status. Kaplan-Meier method was employed to calculate the survival time and plot the survival curves. Log-rank test was used to evaluate the differences between the groups. Cox regressive model was used to analyze the prognostic factors. Results All patients died by the end of follow-up. The survival time ranged from 2 to 732 d and the overall one-year survival rate was 7.9% with a median survival time of 67 d. In multivariate analysis, KPS scores, primary tumor control status, interval between diagnosis of primary tumor and CM were independent prognostic factors. Conclusions The main prognostic factors of CM are KPS scores, primary tumor control status, and interval between diagnosis of primary tumor and CM. The most effective treatment modalities still need to be confirmed and individual treatment for each patient with CM should be recommended in clinic.

OBJECTIVETo observe the clinical effect of Dihuang Zhixue Capsule (DZC, a Chinese preparation for cooling blood and dispelling toxic substances) in the treatment of childhood refractory idiopathic thrombocytopenic purpura (RITP), with cyclosporin A (CsA) used as the control.

METHODSForty-one children of RITP were randomized into the treated group and the control group. The 21 patients in the treated group were orally given 2 to 3 DZC capsules each time, thrice a day and the 20 in the control group were given 3 mg/kg CsA per day, with 3 months as one therapeutic course. The therapeutic efficacy, platelet count and adverse reaction in the two groups were compared at the end of the course.

RESULTS(1) In the treated group, 1 (4.8%) patient was evaluated as cured, 3 (14.3%) as markedly effective, 5 (23.8%) as effective, 5 (23.8%) as improved, 7 (33.3%) as ineffective, with the total effective rate being 66.7%; while in the control group, the corresponding numbers were 0, 2 (10.0%), 2 (10.0%), 3 (15.0%), 13 (65.0%) and 35.0%, respectively, showing statistical significance in difference between the total effective rates of the two groups (xi(2)=4.11, P=0.0426). (2) As compared with the baseline, the platelet count increased in both groups after 2 months' treatment (P<0.05). After 3 months' treatment, the platelet count was higher in the treated group than in the control group (P<0.05). (3) The improvement of hemorrhage in the treated group after 8 weeks' treatment was better than that in the control group (P<0.05). (4) No apparent adverse reaction was observed in the treated group, while in the control group, hirsutism was shown in 15 cases; gingival hyperplasia in 10; digestive reaction in 5, liver function impairment in 5, hypertension in 2 and renal impairment in 2.

CONCLUSIONThe therapeutic efficacy of DZC is better than that of CsA, and DZC shows good compliance but brings no obvious adverse reaction.

OBJECTIVETo study the expression level and clinical significance of miR-181c-3p and miR-5692b in esophageal cancer.

METHODSThe microRNA (miRNA) profiles of esophageal squamous cell carcinoma were analyzed by miRNA microarray in 55 cases of esophageal cancer. The expression levels of miR-181c-3p and miR-5692b from 55 pairs of tumor tissues and adjacent non-neoplastic tissues were determined by qRT-PCR analysis.

RESULTSBoth miR-181c-3p and miR-5692b were significantly up-regulated in tumor tissues compared with adjacent non-neoplastic tissues. Their expression was also significantly associated with tumor size, depth of invasion and clinical tumor stage (P<0.05). High expression of miR-181c-3p and miR-5692b were significantly associated with poor prognosis (P<0.05). Multivariate Cox regression analysis confirmed that high expression of miR-181c-3p and miR-5692b was poor prognostic indicators in esophageal cancer.

CONCLUSIONSThere are significant correlation between miR-181c-3p/miR-5692b expression, clinicopathologic parameters and prognosis. They represent potential prognostic biomarkers in esophageal squamous cell carcinoma.
