Objective To compare the effectiveness and safety of raltitrexed and fluorouracil(FU)/leucovorin (LV) combined with oxaliplatin for advanced colorectal cancer. Methods Fifty patients with advanced colorectal cancer diagnosed by histopathology or cytology were randomly divided into two groups with 25 cases each by envelope, but 1 case lost. Patients in experimental group were treated with raltitrexed (3 mg/m2, ≥ 15 min intravenously) combined with oxaliplatin (130 mg/m2 on day 1 ), patients in control group were treated with FU/LV combined with oxaliplatin:LV 100 mg/m2 infusion (over 2 h, from day 1 to day 3 ) followed by FU (400 mg/m2 infusion in 2 h and 600 mg/m2 continuous infusion from day 1 to day 3 ),combined with oxaliplatin ( 130 mg/m2 on day 1 ), 3 weeks were as one cycle. Patients received 6 or less cycles until disease progressed or toxicity could not be tolerated. Results Effective rate was 37.50%(9/24)and 33.33%(8/24) in experimental group and control group respectively (P＞ 0.05). Disease control rate in experimental group was 83.33% (20/24) while in control group was 70.83% ( 17/24 ) (P ＞ 0.05 ). The median time of progression-free survival (PFS) in experimental group and control group was 11.0 months and 9.0 months respectively (95%CI 8.643-11.357,P =0.015). Main adverse effects were anorexia, vomiting, neutropenia, thrombopenia, anemia, neurotoxicity, fatigue, aminotransferase abnormality, and so on. There was no statistic difference between two groups in side effects(P ＞ 0.05). Conclusions Raltitrexed combined with oxaliplatin is an effective regimen for the advanced colorectal cancer. Compared with traditional FU-based regimen, it is more convenient. Patients will have less venous exposure time and hospital days.Effective rate and mean survival time are superior or not inferior in raltitrexed treatment to that of FU-based regimen. Raltitrexed combined with oxaliplatin is worthy to be recommended in treating colorectal cancer.

OBJECTIVETo evaluate the objectivity and comprehensiveness of Response Evaluation Criteria of Traditional Chinese Medicine for Solid Tumor (Draft, REC-TCM-ST) in application of Chinese medicine therapeutic effect in patients with advanced non-small cell lung cancer (NSCLC).

METHODSA retrospective clinical research was used in 104 NSCLC patients in stages of III-IV, 53 cases were in Chinese medicine (CM) group and 51 cases were in Western medicine (WM) group. The therapeutic effect of the two groups was evaluated with both REC-TCM-ST and Response Evaluation Criteria in Solid Tumor (RECIST). Kaplan-Meier method was used to analyze the survival time. Kappa test method was used to test the consistency of the two kinds of evaluation results.

RESULTSAccording to REC-TCM-ST, the effective rate on relieving tumor mass in the CM group was significantly lower than that in the WM group (P<0.05), but there was no significant difference in tumor-mass stable rate (P>0.05); the symptom of weakness in the CM group was improved significantly, indicating better therapeutic effect than that in the WM group (P<0.01). Karnofsky score in the CM group was significantly better than that in the WM group (P<0.01). In terms of survival conditions, the median survival time and the survival rate of 6 months, 1 year and 2 years of the CM group were higher than the WM group. The total effective rate was 9.62%, and the total stable rate was 72.12% for 104 cases according to RECIST; while the total effective rate was 34.62%, and the total stable rate was 84.62% according to REC-TCM-ST, thus there were significant differences between the results of the two criteria (P<0.01), and there was also some consistency between them, but not satisfactory.

CONCLUSIONSREC-TCM-ST was used to evaluate the therapeutic effect of CM in the treatment of advanced NSCLC, which shows that its evaluation results can better reflect the advantages and disadvantages of CM, and the effectiveness of CM is more objective and comprehensive than RECIST, so REC-TCM-ST is worthy of further improvement and clinical expansion.

Objective To assess the influences of low-protein diet on the renal function and nutritional status in patients with stage 3/4 chronic kidney diseases (CKD).Methods Totally 34 patients with stage 3/4 CKD were randomly divided into group A (protein intake:0.6 g·kg~(-1)·d~(-1);n=14) and B (protein intake:0.8 g·kg~(-1)·d~(-1);n=20).Anthropometric measurement and blood biochemical tests were performed,nutri-tional status was assessed,and 24-hour dietary recall survey was conducted before and after the treatment.Patients were followed up for 6 months.Results In group A,the creatinine level significantly decreased (P=0.010),while albumin level (P=0.042) and the intake of energy (P=0.018) and carbohydrate (P<0.001) signifi-cantly increased after the treatment In all the 34 patients,in group A and group B,the malnutrition rates were de-creased by 14.7%,7.2%,and 21.1% after nutritional intervention.Conclusion The low-protein diet (protein intake 0.6 g·kg~(-1)·d~(-1)),in which part of the staple food was replaced by wheat starch,can increase the in-takes of carbohydrate and energy and improve renal function and nutritional status in patients with stage 3/4 CKD.

OBJECTIVETo investigate the cell features of 6 Castleman's disease patients and evaluate their prognosis.

METHODSThe resected tumors were investigated by routine histopathology and immunohistochemistry. Reverse-transcript PCR (RT-PCR) and sequencing of RT-PCR products were used to assess the clonal characters of the main tumor cells.

RESULTSHistologically, all of the 6 tumors were classified as the hyaline vascular type. B-cells dominated the follicular germinal centers, with T-cells dispersing inter-follicularly. The results of RT-PCR each obtained a single band of either 128 bp or 122 bp and sequencing showed that there was highly homogeneity within the same length sequences, accompanied by fewer different nucleotide acids.

CONCLUSIONMonoclonal and/or oligoclonal B cells were identified in Castleman's disease. These B cells were originated from germinal center cells.

A novel method was developed for the rapid determination of multi-indicators in corni fructus by means of near infrared (NIR) spectroscopy. Particle swarm optimization (PSO) based least squares support vector machine was investigated to increase the levels of quality control. The calibration models of moisture, extractum, morroniside and loganin were established using the PSO-LS-SVM algorithm. The performance of PSO-LS-SVM models was compared with partial least squares regression (PLSR) and back propagation artificial neural network (BP-ANN). The calibration and validation results of PSO-LS-SVM were superior to both PLS and BP-ANN. For PSO-LS-SVM models, the correlation coefficients (r) of calibrations were all above 0.942. The optimal prediction results were also achieved by PSO-LS-SVM models with the RMSEP (root mean square error of prediction) and RSEP (relative standard errors of prediction) less than 1.176 and 15.5% respectively. The results suggest that PSO-LS-SVM algorithm has a good model performance and high prediction accuracy. NIR has a potential value for rapid determination of multi-indicators in Corni Fructus.
