There have been few reports of acute leukemia predenting with a hypocellular bone marrow. Our institution, from 1977 to 1986, reviewed 9 cases of hypoplasfic acute leukemia (HAL). We concluded that HAL was similar to as well as different from dysmyclopoietic syndrom (MDS), smouldering acute leukemia(SAL) and oligoblastic leukemia(OBL). It was suggested that the diagnostic crieria of HAL were (1), The patients of no treatment had local hypocellularity of bone marrow, and had more than 30% blasts and promyelocytes of immaturocytes on bone marrow aspirate smears; (2), The patients had hypocellularity at presentation on trephine biopsy. We proposed that the names of SAL and OBC be called off.

Objective To explore the relationship between quality of life and acceptance of disability of colostomy patients.Methods Using convenience sampling method to investigate 111 colostomy patients.General information questionnaire,QLQ-C30 scale,QLQ-CR38 scale and Acceptance of Disability Scale were used to investigate patients' general condition,quality of life and acceptance of disability.Data was analyzed by SPSS 17.0.Results The general health condition of colostomy patients was better than reference value and the score of ADS was at an average level.There was a relationship between general health condition,functioning dimensions,symptom dimensions and acceptance of disability.Conclusions There was a close relationship between quality of life and acceptance of disability.The acceptance of disability should be improved to help patients to obtain better quality of life.

OBJECTIVE: To improve the quality standard of Folium Mahoniae. METHODS: TLC was used for qualitative identification. The contents of moisture, ash and ethanol extract were determined. The content of berberine hydrochloride was determined by HPLC. The determination was performed on WondaSil C18 column with mobile phase consisted of acetonitrile-0. 05 mol/L monopotassium phosphate solution (25: 75, V/V) at the flow rate of 1. 0 mL/min. The detection wavelength was 264 nm, column temperature was 30 ℃, and sample size was 10 μL. RESULTS: TLC spots were clear and well-separated. The contents of moisture, total ash, acid-insoluble ash and ethanol extract were 3. 92％-7. 03％, 3. 65％-6. 95％, 0. 05％-1. 03％ and 10. 87％-33. 14％, respectively. The linear range of berberine hydrochloride was 0. 183-0. 915 μg(r=0. 999 9); quantitation limit and detection limit was 0. 143, 0. 095 μg, respectively. RSDs of precision, stability and reproducibility tests were lower than 2. 0％ (n=6); recovery was 95. 21％ -103. 10％ (RSD = 2. 95％, n=6). CONCLUSIONS: The content of moisture, total ash and acid-insoluble ash of medicinal materials is not exceed 8. 0％, 6. 0％ and 0. 4％, respectively. The content of ethanol extract and berberine hydrochloride is not less than 16. 0％ and 1. 0％, respectively. Established standard can be used for quality control of Folium Mahoniae.

Objective To apply Nutritional Risk Screening-2002(NRS-2002) to perform primary screening for nutritional risk in patients with esophageal cancer who undergo radiotherapy, and assess their nutritional status, and to investigate the value of NRS-2002 in such patients.Methods A total of 97 patients who were diagnosed with esophageal cancer and underwent radiotherapy in Zhejiang Cancer Hospital from January 2010 to April 2014 were analyzed retrospectively.The Kaplan-Meier method was applied to analyze the difference in survival, and the chi-square test and the Pearson correlation analysis were applied to analyze the correlation between NRS-2002 score and blood parameters.Results Of all patients, 26.8%had nutritional risk before radiotherapy, which gradually increased with the progress of radiotherapy.The 1-year overall survival rates of the patients with NRS-2002scores of ≤3 and ≥4 on admission were 91.1%and 61.9%, respectively (P=0.010).As for the patients with the highest NRS-2002 scores of ≤2 and ≥3 during treatment, the 1-year overall survival rates were 94.2% and 77.5%, respectively (P=0.012).As for the patients with the lowest NRS-2002 scores of ≤3 and ≥4 during treatment, the 1-year overall survival rates were 91.3% and 54.5%, respectively ( P=0.018).The NRS-2002 score was correlated with prealbumin on admission and at week 1 of radiotherapy (P=0.000 and 0.002), and the NRS-2002 score was correlated with albumin at week 3 of radiotherapy (P=0.036).The multivariate analysis showed that the TNM stage of esophageal cancer and the highest NRS-2002 score during treatment were the independent prognostic factors in esophageal cancer (P=0.001 and 0.005).Conclusions The patients with esophageal cancer undergoing radiotherapy have high nutritional risk, and NRS-2002 score is the independent prognostic factor in these patients and can be used as a tool for primary screening for nutritional risk.

Objective:To evaluate the 5-year survival outcome of patients with unresectable locally advanced non-small cell lung cancer (NSCLC) treated with Endostar in combination with platinum-based concurrent chemoradiotherapy.Methods:From March 2009 to June 2015, 115 patients with the unresectable locally advanced NSCLC from two prospective studies[Clinical trials 2009-2012(ClinicalTrials.gov NCT01894) and 2012-2015(ClinicalTrials.gov, NCT01733589)] were treated with Endostar in combination with platinum-based concurrent chemoradiotherapy. A total dose of 60-66 Gy was delivered in 30-33 fractions. Endostar was given 1 week prior to the beginning of radiotherapy, and repeated fortnightly during the concurrent chemoradiotherapy. After long-term follow up, survival outcome was evaluated in 104 patients treated with radiation dose of ≥60 Gy. Kaplan-Meier method was used for survival analysis. Univariate survival analysis was performed using the log-rank test.Results:Of 104 eligible patients, 60.6% of them had squamous carcinoma and 65.4% were classified in stage Ⅲ B. All the patients received ≥2 cycles of Endostar and 93.3% of them received 4 cycles of Endostar. The median follow-up time was 68.3 months. The median overall survival (OS) and median progression-free survival (PFS) were 31.3 and 13.9 months, respectively. The 3-year and 5-year OS were 45.6% and 35.7%, respectively. The 3-year and 5-year PFS were 27.1% and 24.9%, respectively. Univariate analysis indicated that sex, ECOG, pathological type, clinical stage, radiotherapy technique, chemotherapy regimen, chemotherapy cycle and cycle of Endostar use were not associated with OS. Late radiation injury occurred in 14.4% of patients, and no grade 4-5 late injury was observed. Conclusion:Patients with unresectable locally advanced NSCLC treated with Endostar fortnightly in combination with platinum-based concurrent chemoradiotherapy achieve better OS than historical data with tolerable toxicities.

Objective To investigate the effects of hyperfractionated radiotherapy versus hypofractionated radiotherapy combined with concurrent chemotherapy on the prognosis of limited-stage small-cell lung cancer (SCLC).Methods A total of 188 patients with limited-stage SCLC were enrolled in this study and divided into hyperfractionated group (n=92) and hypofractionated group (n=96).The hyperfractionated group received thoracic radiotherapy at 45 Gy in 30 fractions twice a day, while the hypofractionated group received 55 Gy in 22 fractions once a day.The Kaplan-Meier method was used to calculate survival rates, and the Cox model was used for multivariate prognostic analysis.Results There were not significant differences in 1-, 2-, and 5-year progression-free survival (PFS) rates and 1-, 2-, and 5-year overall survival (OS) rates between the hyperfractionated group and the hypofractionated group (82% vs.85%, 61% vs.69%, 59% vs.69%, P=0.27;85% vs.77%, 41% vs.34%, 27% vs.27%, P=0.37).The multivariate analysis showed that the time from the initiation of chemotherapy to the initiation of thoracic radiotherapy ≤43 days was favorable prognostic factor for PFS (P=0.005).The time from the initiation of chemotherapy to the end of thoracic radiotherapy ≤63 days and prophylactic cranial irradiation were favorable prognostic factors for OS (P=0.044;P=0.000).There were significant differences in incidence rates of grade 2 and 3 acute radiation esophagitis between the two groups (28% vs.16%, 9% vs.2%, P=0.009).Conclusions Both hyperfractionated radiotherapy and hypofractionated radiotherapy combined with chemotherapy can improve the PFS and OS of patients with limited-stage SCLC.The time from the initiation of chemotherapy to the initiation of thoracic radiotherapy ≤43 days and the time from the initiation of chemotherapy to the end of thoracic radiotherapy ≤63 days are favorable prognostic factors for PFS and OS, respectively.However, the hyperfractionated group has significantly higher incidence rates of grade 2 and 3 acute radiation esophagitis than the hypofractionated group.

Mitochondrial DNA (mtDNA) common deletion (CD) plays a significant role in aging and age-related diseases. In this study, we used D-galactose (D-gal) to generate an animal model of aging and the involvement and causative mechanisms of mitochondrial damage in such a model were investigated. Twenty 5-week-old male Sprague-Dawley rats were randomly divided into two groups: D-gal group (n=10) and control group (n=10). The quantity of the mtDNA CD in the hippocampus was determined using a TaqMan real-time PCR assay. Transmission electron microscopy was used to observe the mitochondrial ultrastructure in the hippocampus. Western blot was used to detect the protein levels of NADPH oxidase (NOX) and uncoupling protein 2 (UCP2). We found that the level of mtDNA CD was significantly higher in the hippocampus of D-gal-induced aging rats than in control rats. In comparison with the control group, the mitochondrial ultrastructure in the hippocampus of D-gal-treated rats was damaged, and the protein levels of NOX and UCP2 were significantly increased in the hippocampus of D-gal-induced aging rats. This study demonstrated that the levels of mtDNA CD and NOX protein expression were significantly increased in the hippocampus of D-gal-induced aging rats. These findings indicate that NOX-dependent reactive oxygen species generation may contribute to D-gal-induced mitochondrial damage.

ObjectiveTo evaluate the local failure and the impact on survival by prospectively comparing involved field radiotherapy (IFRT) and elective nodal irradiation (ENI) in combination with concurrent chemotherapy for locally advanced non-small cell lung cancer ( LA-NSCLC ).Methods LANSCLC patients were treated with 2 cycles of carboplatin ( AUC =5 - 6,d1 ) combined with paclitaxel ( 175mg/m2 ),followed assessment without distant metastasis,then randomized into IFRT (45 patients) or ENI (54 patients) arm.IFRT included primary tumor,ipsilateral hilar and positive mediastinal lymph nodes;ENI included the primary lesion,ipsilateral hilar,hilateral mediastinal lymph node drainage and bilateral supraclavicular area.The prescription dose was given as high as possible with V20 ≤35％ and spinal cord dose ≤50 Gy,combined weekly paclitaxel 40 mg/m2 concurrent chemotherapy.The Kaplan-Meier method was used to estimate survival data and the log-rank method was used to test distribution of survival time between arms.ResultsThe follow-up rate was 99％.49,29 and 17 patients were followed-up for 1-,2-and 3-year,respectively.More patients from group IFRT received ＞60 Gy than ENI (49％ vs.26％,x2 =5.59,P =0.018 ).The local failure rates were 29％ and 36％,respectively ( x2 =0.46,P =0.497 ).The 1-,2-and 3-year local tumor progression-free survival rates were 76％,69％,65％ and 80％,53％,49％ ( x2 =0.74,P =0.389),respectively; the 1-,3-and 5-year overall survival rates were 80％,41％,33％ and 69％,32％,13％ (x2 =3.97,P =0.046),respectively.There were no significant differences in acute and late toxicities between the arms ( x2 =3.910 - 0.155,P =0.142 - 0.925 ).ConclusionsIFRT improved radiation dose and survival rate and did not increase the failure of elective lymph node region compared with ENI.The toxicities were no differences between IFRT and ENL Further investigation with big size sample is warranted.

Objective To evaluatc the efficacy and safcty of recombinant endostatin (Endostar)combined with concurrent radio-chemotherapy (CRCT) in patients with unresectable stage Ⅲ non-small cell lung cancer (NSCLC).Methods From March 2009 to November 2011,47 patients received threedimensional conformal radiotherapy of 60-66 Gy in 30-33 fractions over 6-7 weeks And concurrent chemotherapy of docetaxel 65 mg/m2 and cisplatin 65 mg/m2.Endostar was administered once a week before and on week 2,4,6 during CRCT at a dose level of 7.5 mg/m2/d.Tumor response was evaluated with thoracic CT scans performed 4 weeks after completion of treatment in accordance with RECIST 1.1 criteria.Acute toxicities were evaluated in accordance with CTCAE 3.0.Results Forty-four patients completed treatment and toxicity evaluation,42 patients completed evaluation of efficacy.Five patients achieved complete response,29 partial response,3 stable disease,and 5 progressive disease,2 were net assessed.Overall response rate was 77％.One-year overall survival rate was 81％,and one-year progression-free survival rate was 51％.Twelve patients died,2 died of treatment related toxicities,8 of cancer,and 2 of unknown causes.Nineteen patients developed grade 3/4 neutrocytopenia,grade 3 acute esophagitis and pneumonitis were observed in 4 and 4 patients,respectively,and 1 patient died of pneumonitis.No patient developed cardiovascular toxicities and hemorrhage.Conclusions Endostar combined with CRCT for unresectable stage Ⅲ NSCLC was safe and the short term outcomes were promising.Further investigations are warranted.
