Acute kidney injury (AKI) is the complex clinical syndrome attributed to multiple causes and risk factors, which is characterized by an abrupt loss of renal function. Metabonomics, recently advances in the field of omics, is the nontargeted measurement of all of the low-molecularweight compounds that appear in a particular cell, tissue, organ or biofluid in a living organism. Compared to genomics, transcriptomics and proteomics,metabonomics has its unique advantages, including fewer metabolites than genes, transcripts and proteins, the most accurate predictors of the signature of the actual processes, easy access to biofluids. Thus, metabonomics makes it possible to find new biomarkers for AKI on early diagnosis, identifying new metabolic pathways, finding new targets for drug therapy and individual medical treatment.

Objective To investigate the feasibility of the scheme of target volume delineation with extended involved?field intensity?modulated radiotherapy (IMRT) for patients with early?stage nasal NK/ T?cell lymphoma (NC?NKTL). Methods Twenty?one patients with stage IE?IIE NC?NKTL were treated with short?course chemotherapy combined with radiotherapy from 2011 to 2013. The majority of patients received the GELOX regimen. All patients received extended involved?field IMRT with a dose of 54?? 6 Gy in 26 fractions for gross tumor volume, 50?? 7 Gy in 26 fractions for high?risk clinical target volume (CTV), and 45?? 5 Gy in 26 fractions for low?risk CTV. The dose distribution, short?term treatment outcomes, and adverse reactions were analyzed. Results The 2?year sample size was 12. The 2?year follow?up rate was 100%. The 2?year local control rate ( LRC) was 100%. The 2?year overall and progression?free survival rates were 90?? 5% and 90?? 5%, respectively. The median coverage rates of planning target volumes with 90% of the prescribed doses of 54?? 6 Gy, 50?? 7 Gy, and 45?? 5 Gy were 99?? 8%, 99?? 6%, and 99?? 7%, respectively. No grade 3 or 4 adverse reactions were observed in patients. Conclusions The scheme of target volume delineation and dose configuration in our study not only achieves excellent target volume coverage, but also reduces adverse reactions in patients, which achieves a 2?year LRC ideal for patients with early?stage NC?NKTL.

Objective To retrospectively analyze the prognostic factors for locoregionally recurrent early?stage extranodal nasal?type natural killer/T?cell lymphoma ( NKTCL) . Methods A total of 56 patients with early?stage extranodal nasal?type NKTCL, who had locoregional recurrence after initial treatment and then received salvage treatment from 1995 to 2014, were enrolled as subjects. The effects of salvage treatment on the overall survival ( OS) rate were analyzed after initial treatment and recurrence. Univariate and multivariate prognostic analyses were performed on the OS rate after recurrence. Results The median follow?up time was 35. 9 months after initial treatment and 14. 8 months after recurrence. The 3?year OS rate was 73% after initial treatment and 58% after recurrence. Compared with chemotherapy alone, radiotherapy?containing salvage treatment significantly improved the OS rates after initial treatment and recurrence ( P=0. 040, 0. 009 ) , and re?irradiation also significantly improved the OS rates after initial treatment and recurrence (P=0. 018, 0. 019). Most (84%) of the acute and late adverse reactions after re?irradiation were grade 1?2 ones. The univariate and multivariate analyses showed that the Karnofsky Performance Status score, radiotherapy in initial treatment, and radiotherapy in salvage treatment were influencing factors for the OS rate after recurrence. Conclusions Radiotherapy achieves improved survival and tolerable toxicities, making it indispensable in the treatment of locoregionally recurrent extranodal nasal?type NKTCL.

Objective To analyze the clinical features,treatment methods,and prognostic factors for early primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma.Methods A retrospective analysis was performed on the clinical data,treatment outcomes,and survival of 32 patients with early pulmonary MALT lymphoma from March 2001 to September 2013.The median age of those patients was 56 years.Twenty-three patients had stage ⅠE disease and nine had stage Ⅱ E disease.According to the marginal zone B-cell lymphoma prognostic index (MZLPI),twenty-three patients were scored as 0 and nine as 1.Nine patients received radiotherapy,eight patients underwent surgery alone,three patients underwent surgery plus chemotherapy,and twelve patients received chemotherapy alone.The Kaplan-Meier method was adapted for calculating the OS,PFS and the log-rank test was used for survival difference analysis and univariate prognostic analysis.Results The 5-year sample size was 22.The 5-year overall survival (OS) and progression-free survival (PFS) rates were 84.5％ and 73.2％,respectively.Radiotherapy yielded an overall response rate of 100％,including a complete response rate of 66.7％ and a partial response rate of 33.3％.The univariate analysis showed that non-radiotherapy treatment was a prognostic factor for poor PFS.The patients treated with radiotherapy had significantly higher 5-year PFS rates than those treated without radiotherapy (100％ vs.63.0％,P=0.029),while there was no significant difference in 5-year OS rate between these two groups (100％ vs.78.8％,P=0.129).Age older than 60 years,an ECOG score of 2,and an MZLPI score of 1 were prognostic factors for poor PFS (P=0.041,0.018,and 0.044) and OS (P=0.001,0.001,and 0.003).Conclusions The prognostic factors for early pulmonary MALT lymphoma include age,ECOG score,and MZLPI score.Low-dose involved-field radiotherapy (24-30 Gy) can improve local control and survival.

Objective To investigate the efficacy and adverse reactions of azithromycin sequential therapy for the treatment of children with mycoplasma pneumonia.Methods 84 children with mycoplasma pneumonia were randomly divided into study group and control group according to the digital table,with 42 cases in each group.The study group was given azithromycin treatment,and the control group was given erythromycin treatment.The clinical curative effect and adverse reaction were compared between the two groups.Results The total effective rate of the study group (97.62％) was significantly higher than that of the control group (76.19％),and the difference was statistically significant (x2 =11.95,P ＜ 0.05).The pyretolysis time [(3.78 ± 1.57) d],cough improvement time [(3.29 ± 0.74) d],rate disappearance time[(5.88 ± 2.35) d],average hospitalization time [(8.89 ± 1.76) d] of the study group were significantly shorter than those of the control group [(4.49 ± 1.71) d,(4.28 ± 0.77) d,(7.69 ±2.54) d,(10.05 ± 2.27) d],and the differences were statistically significant (t =2.01,6.33,3.29,2.46,all P ＜0.05).The incidence rate of adverse reactions such as nausea,abdominal distention,abdominal discomfort,local injection pain,rash,elevated alanine aminotransferase of the study group (4.76％) was significantly lower than that of the control group (19.05％),and the difference was statistically significant (x2 =4.86,P ＜ 0.05).Conclusion Azithromycin sequential therapy is effective in the treatment of children with mycoplasma pneumonia.It can effectively shorten the disappearance time of clinical symptoms and signs,and average hospitalization time,and has low incidence rate of adverse reactions.It is worthy of clinical use.

Objective To estimate the diagnostic vaule of circulating tumor cells (CTCs) detection for epithelial ovarian cancer,and investigate the relationship between the presence of CTCs and the clinic pathologic characteristics of epithelial ovarian cancer patients.Methods Quantification of CTCs were performed using immunomagnetic bead based negative enrichment combined with flow cytometry in 65 patients with epithelial ovarian cancer,21 patients with benign ovarian diseases,and 10 healthy subjects.The differences among groups were analyzed by the Kruskal-Wallis H test (multi group comparison) and the Mann-Whitney U test (two group comparison),and the chi-square test was used in the positive rate comparison,the receiver operating characteristic (ROC) curve was established.The relationship between CTCs and clinic pathologic characteristics of epithelial ovarian cancer patients were analyzed.Results The receiver operating characteristic analysis showed the cut off value was 4.5 (＞ 4),the AUC was 0.806,and sensitivity,specificity and positive value (PPV) were 55.4 ％,96.8 ％ and 97.3 ％ respectively,in detecting patients with ovarian carcinoma malignancy.Quantification of CTCs in epithelial ovarian cancer was correlated with FIGO stages or distance metastasis (all P＜0.05),but not with patient age,histological types,pathologic differentiation,amount of ascites,tumor size and lymph node metastasis (all P＞0.05).Conclusion The detection of peripheral CTCs has a certain diagnosis value in epithelial ovarian cancer,especially with related to FIGO stages and distant metastasis.
