Microvesicles (MVs) are the heterogeneous mixtures of vesicles. MVs released by leukemia cells constitute an important part of the leukemia microenvironment. MVs might act as important reservoirs of microRNAs (miRNAs). It is worth evaluating whether MVs possess some unique miRNA contents that are valuable in understanding the pathogenesis. In this study, we investigated the miRNA expression patterns of Nalm-6-derived MVs, Jurkat-derived MVs and normal cell-derived MVs using miRNA microarrays. The potential target genes regulated by differentially expressed miRNAs were also predicted and analyzed. Results demonstrated that 182 miRNAs and 166 miRNAs were differentially expressed in Nalm-6-MVs and Jurkat-MVs, respectively. Many oncogenes, tumor suppressors and signal pathway genes were targeted by these aberrantly expressed miRNAs, which might contribute to the development of B-ALL or T-ALL. Our findings expanded the potential diagnostic markers of ALL and provided useful information for ALL pathogenesis.

AIM:To assess changes of tear film function in patients after pterygium excision combined with amniotic membrane transplantation.
METHODS:Totally 126 patients with pterygium excision with amniotic membrane transplantation from January 2011 to November 2013 were entered in the study. The tear breakup time ( BUT) , the Schirmer I test ( SⅠt) and tear ferning test ( TFT ) were elevated in the patients before and after pterygium excision combined with amniotic membrane transplantation. The examnation times were 1d before surgey, 1wk, 1, 2mo after surgery. Operation eyes were studied group, while opposite healthy eyes as control group.
RESULTS: Compared with the control group, BUT and TFT were significantly different in the eyes with pterygium (P<0. 05); However, no obvious difference was detected in the results of SⅠt (P>0. 05). The results of BUT and TFT at 1mo after surgery in study group were significantly better than 1wk (P<0. 05), while no significant difference compared with 2mo (P>0. 05); The tear film stability in the study group at 1wk after surgery was still inferior to the control group (P<0. 05) and there was no significant difference at 1, 2mo after surgery (P all>0. 05). SⅠt results did not differ between the different examination times(P>0. 05).
CONCLUSION:Tear film stability was broken in the eyes with pterygium. Pterygium excision combined with amniotic membrane transplantation can obviously restore the tear film function into normal state, and the tear film function could reach steady-state 1mo after surgery.

Objective To evaluate the levels of oxidative stress in patients undergoing long-term and repetitive exposure to hyperbaric oxygen (HBO) treatment. Methods 16 healthy volunteers and 58 patients with sub-acute sudden hearing loss (SHL) exposed to HBO were included in the study. Oxidative stress indices (malondialdehyde, MDA, advanced oxidation protein products, AOPP; superoxide dismutase, SOD) were measured in peripheral blood samples collected at the 5th,10th, 20th and 30th HBO treatments sessions (PO2 0.18 MPa, 1 session per day and 5 sessions per week) and under normal ambient pressure respectively. Results After 5th,10th, 20th and 30th sessions of HBOT, no relevant differences in these three indices were detected compared to pre-HBO exposure, between healthy volunteers (P > 0.05). Conclusions The long-term repetitive HBO treatment for 0.18 MPa of PO2 and 30 sessions could not affect in particular the response of the oxidative stress in healthy persons and patients with sub-acute SHL. The influence on three indices of patients with abnormal situation of oxidative stress undergoing lower pressure of HBO (0.18 MPa) is under investigation.

Objective To evaluate the efficacy and safety of colistimethate sodium (CMS) for the treatment of critical patients infected by pan-drug resistantAcinetobacter baumannii (PDR-AB) or pan-drug resistant Pseudomonas aeruginosa (PDR-PA).Methods 321 isolates of PDR-AB and 204 isolates of PDR-PA from critical patients admitted to 35 intensive care units (ICUs) of grade two or above were collected from the Anhui Antimicrobial Resistance Investigation Net (AHARIN) program from September 2012 to September 2015, while the minimal inhibitory concentrations (MIC) of colistin were determined by the E-test. A series of Monte Carlo simulations was performed for CMS regimens (1 MU q8h, 2 MU q8h, and 3 MU q8h, and MU meant a million of unit), and the probability of achieving a 24-hour area under the drug concentration time curve (AUC24)/MIC ratio > 60 and risk of nephrotoxicity for each dosing regimen was calculated. Each simulation was run over three CLCr ranges: < 60, ≥ 60-90, ≥ 90-120 mL/min. The probability of target attainment (PTA)for the AUC24/MIC ratio was calculated using the partial MIC value, while the cumulative fraction of response (CFR) was determined by integrating each PTA with the MIC distributions, the value greater than or equal to 90% or more than 80% was set as the optimal dosing regimen or suboptimal dosing regimen respectively. The probability of average 24-hour serum concentrations up to 4 mg/L for three dosage regimens was used to predict the risks of nephrotoxicity.Results All 321 isolates of PDR-AB and 204 isolates of PDR-PA were susceptible to colistin, the MIC50/90 against PDR-AB were 0.5mg/L and 1.0 mg/L, and those against PDR-PA were 0.5 mg/L and 1.5 mg/L, respectively. When recommended dose (1 MU q8h) was used for patients with CLCr of < 60 mL/min, high CFR value (89.78% for PDR-AB, 81.06% for PDR-PA) were obtained, but with a high risks of nephrotoxicity (> 32.51%). Moreover, low value of PTA (< 66.56%) was yielded for isolates with MIC of ≥ 1 mg/L. Recommended dose also yielded a low CFR value (56.97%-69.31% for PDR-AB, 44.76%-56.94% for PDR-PA) in patients with CLCr of ≥ 60-120 mL/min. When dose was increased to 2 MU q8h, CFR (77.45%-92.87%) and the risks of nephrotoxicity (< 0.15%) was optimal for patients with CLCr ≥ 60-120 mL/min, but low value of PTA (< 75.36%) was also yielded for isolates with MIC of ≥ 1 mg/L. The most aggressive dose of 3 MU q8h provided high CFR (> 89.24%) even in patients with CLCr ≥ 90-120 mL/min, and PTA was < 76.20% only for isolates with MIC of ≥ 1.5 mg/L, but this dosing scheme was associated with unacceptable risks of nephrotoxicity (> 33.68%).Conclusion Measurement of MIC, individualized CMS therapy and therapeutic drug-level monitoring should be considered to achieve the optimal drug exposure and ensure the safety of CMS.

OBJECTIVETo study the effects of Chinese materia medica (CMM) combined chemotherapy on the recurrence, metastasis, and the disease free survival (DFS) of stage II and III colorectal cancer (CC) patients after radical cure.
METHODSRecruited were 366 inpatients and outpatients with stage II and III colorectal cancer (CC) from Changhai Hospital, Second Military Medical University, and Tumor Department of Longhua Hospital, Shanghai University of Traditional Chinese Medicine from January 2002 to December 2008. A non-randomized concurrent control method was adopted. Patients were assigned to the combination group (treated by CMM + chemotherapy, 189 cases) and the chemotherapy group (177 cases) according to whether they were willing to receive the CMM treatment for more than 6 successive months. By using follow-ups at clinics, by letter, and by telephone, the DFS, 1-, 2-, 3-, and 5-year DFS ratios were observed. The correlations between DFS and the gender, age, tumor location, staging of clinical pathology, pathological type, chemotherapeutic cycle, radiotherapy, CMM treatment, end point event (recurrence and metastasis) were analyzed.
RESULTSThe recurrence or metastasis occurred in 145 cases (39. 61%) of the 366 patients. Of them, local recurrence occurred in 17 cases (11.72%), liver metastasis in 45 cases (31.03%), lung metastasis in 52 cases (35.86%), and metastasis in other parts in 53 cases (36.55%). Results of one-factor analysis showed six factors such as the tumor location, pathological type, staging of clinical pathology, chemotherapeutic cycle, radiotherapy, and CMM treatment were correlated with the DFS, showing statistical difference (P<0.01, P<0.05). Results of multifactor analysis showed staging of clinical pathology, chemotherapeutic cycle, and CMM treatment were correlated with the DFS, showing statistical difference (P<0.01). Results of stratified study on the staging of clinical pathology indicated that the primary tumor location (P=0.016) and the pathological type (P=0.047) were the independent predictors for DFS of stage II CC. The median DFS of the two groups could not be calculated. Results of stratified study on the stages of clinical pathology indicated that CMM treatment (P=0.000) and chemotherapeutic cycle (P=0.017) were independent predictors for DFS of stage III CC. As for comparing the composition ratio of the two therapeutic cycles, results showed the baselines of the chemotherapeutic cycle of the two groups were balanced. Further comparison showed the median DFS for the chemotherapy group at stage III was 24. 16 months, while it could not be calculated in the combination group. The DFS, 1-, 2-, 3-, and 5-year DFS ratios were 92%, 72%, 61%, and 59%, respectively in the stage III CC combination group, while they were 74%, 50%, 36%, and 20%, respectively in the stage IlI CC chemotherapy group.
CONCLUSIONCMM combined chemotherapy could prolong the DFS of stage III CC patients after radical cure.
