Objective To assess the application of Xpert MTB/RIF assay in rapid diagnosis of tuberculous lymphadenitis.Methods Lymph node samples were collected from 1 02 clinically diagnosed patients with lymph node tuberculosis and 65 patients with other lymph node diseases from Zhejiang Provincial Hospital of Traditional Chinese and Western Medicine during January 201 4 and February 201 5. Xpert MTB/RIF,pathological examination and mycobacterium tuberculosis culture were conducted in all specimens of two groups.Taking clinical comprehensive diagnosis as the gold standard,the diagnostic sensitivity,specificity,positive predictive value,negative predictive value and diagnosis efficacy of three detection methods were assessed.The sensitivity of Xpert MTB/RIF in determining rifampicin resistance was analyzed using drug susceptibility testing as gold standard.Results The mean detection time of Xpert MTB/RIF was (2.2 ±0.2)h.Among 1 02 patients,Xpert MTB/RIF achieved higher sensitivity (96.1 %, 98 /1 02 ) than pathological examination (76.5%,78 /1 02 ) and mycobacterium tuberculosis culture (33.3%,34 /1 02)(χ2 =1 6.558 and 87.91 9,both P <0.01 ).Among 65 patients with other lymph node diseases,the specificity of all three detection methods was 1 00%.The receiver-operating-characteristic curve analysis demonstrated that diagnostic performance of Xpert MTB/RIF was better than that of other two methods.In 8 patients resistant to rifampicin confirmed by drug susceptibility testing,Xpert MTB/RIF detected 6 resistant-resistant patients.Conclusion Xpert MTB/RIF shows higher sensitivity and specificity in diagnosis of lymph node tuberculosis with the advantages of easy and rapid performance.

Objective To investigate the correlation between red cell distribution width RDW) and prognosis in patients with severe traumatic brain injury.Methods A total of 264 consecutive patients with severe traumatic brain injury admitted from May 2012 to November 2014 were enrolled.The patients were divided into low-RDW group (RDW ＜ 15％,n =198) and high-RDW group (RDW ≥ 15％,n =66) based on their RDW levels.Between-group differences were evaluated on general conditions,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ),inflammatory markers [high sensitivity C-reactive proteins(hs-CRP) and arterial lactate],liver/renal dysfunction,and 28-day mortality.Spearman correlation analysis of RDW with mortality was conducted.Independent factors of 28-day mortality were identified using multivariate Logistic regression.Kaplan-Meier 28-day survival curve was analyzed and survival probability of the two groups was compared using Log-Rank test.Results The 28-day mortality was significantly enhanced in high-RDW group compared to that in lowRDW group (43.9％ vs 26.8％,P ＜ 0.01).RDW ≥ 15％ related positively to APACHE Ⅱ and mortality(r =0.172 and 0.253 respectively,P ＜ 0.01),but negatively to Glagow coma score (GCS) (r =-0.169,P ＜0.01).RDW≥ 15％ was the independent risk factor for predicting the 28-day mortality (OR =2.144,95％ CI 1.202-3.826,P ＜0.01).After adjusted gender,age,and other relative factors,RDW≥15％ was still strongly correlated with the 28-day mortality(OR =2.244,95％ CI 1.076-4.678,P ＜ 0.05).Significantly lower 28-day survival rate was found in high-RDW group than in low-RDW group (P ＜ 0.01).Conclusions RDW level rises beyond the normal range on admission in patients with severe traumatic brain injury,which is closely correlated with the 28-day poor outcome.RDW≥ 15％ has significant predictive value in the prognosis.

Objective To investigate the effects of miR-135a on HOXA10 expression,proliferation and apoptosis of SKOV3 cells.Methods (1) Through computer-aided algorithms,the predicted target gene of miR-135a (HOXA10)were determined.(2) miR-135a mimics,miR-135a inhibitor and negative control were transfected into SKOV3 cells,respectively.Reverse transcription (RT)-PCR,western blot analysis were used to examine the expression levels of HOXA10 at different times (24,48 and 72 hours).(3) A luciferase reporter assay was used to confirm the direct regulation between miR-135a and HOXA10.(4) SKOV3 cells proliferation at different times (24,48 and 72 hours) was detected by methyl thiazolyl tetrazolium(MTT) assay [quantified by absorbance(A)].Western blot was used to examine the expression of apoptosis-associated protein bcl-2,bax and caspase-3 in SKOV3 cells after 48 hours transfection.Results (1) HOXA10 was predicted to be the target gene of miR-135a by computer-aided algorithms.(2) RT-PCR shown that HOXA10 mRNA levels were decreased over time (24,48 and 72 hours) after miR-135a mimics transfectionin SKOV3 cells (0.94 ±0.04 vs 0.78 ±0.03 vs 0.70 ±0.03,P ＜0.05).While,the expression of HOXA10 mRNA was increased over time after miR-135a inhibitor transfection (1.14 ± 0.05 vs 1.16 ±0.03 vs 2.60 ±0.08,P ＜0.05).After transfected with miR-135a mimics or miR-135a inhibitor over 48 and 72 hours,the HOXA10 expression levels in SKOV3 cells were significantly lower or higher than each control group,respectively (all P ＜ 0.01).Western blot analysis of HOXA10 expression in SKOV3 cells confirmed the results of RT-PCR detected.(3) After cotransfection of miR-135a plasmid and pMIR-REPORT luciferase plasmid containing HOXA10,luciferase reporter assays showed that the luciferase activity reduced by 67.8％ (P ＜0.01).(4) MTT showed that SKOV3 cells growth after miR-135a mimics transfection for 48 and 72 hours were significantly lower than those in control group (0.38 ± 0.03 vs 0.52 ± 0.05,0.67 ±0.05 vs 0.75 ± 0.06 ; respectively,all P ＜ 0.05).While,SKOV3 cells transfected with miR-135a inhibitor for 72 hours grew significantly faster than that in control group (0.95 ± 0.05 vs 0.75 ± 0.06,P ＜ 0.01).After miR-135a mimics transfection,the level of bcl-2 protein was significantly lower than that in control group (0.28 ±0.06 vs 0.76 ±0.09,P ＜0.01).The activity of caspase-3 was significantly higher than that in control group (115.0 ± 2.4 vs 95.4 ± 2.1,P ＜ 0.01).While,there was no statistical difference of bax expression (P =0.142).However,after miR-135a inhibitor transfection,the expression level of bcl-2 protein was significantly higher than that in control group (0.92 ± 0.03 vs 0.76 ± 0.09,P =0.037) and the activity of caspase-3 was significantly lower than that in control group (59.5 ± 4.1 vs 95.4 ± 2.1,P ＜ 0.01).There was also no statistical difference of bax expression (P =0.066).Conclusion miR-135a may play an important role in cell proliferation and apoptosis of ovarian cancer cells by regulating HOXA10 and its downstream pathways.

Objective To investigate the inhibition effect in vitro of mucin gene MUC2 antisense oligodeoxynucleotide (ASODN) on its gene expression and proteolytic enzyme on gastric cancer cell line. Methods Phosphorothioated MUC2 ASODN were synthesized and transfected to SGC7901 cells mediated by lipofectin. MUC2 mRNA and MUC2 protein expressed on SGC7901 cells was detected by RT-PCR and immunohistochemical method. The inhibitory effects of ASODN on proteolytic enzyme, such as cathepsin D, MMP-2 and MMP-9 protein were detected by immunohistochemical staining. The cell cycle and apoptosis were determined by flow cytometry (FCM). Results The inhibition effects peaked at 48th hour after transfection, and the inhibition rate reached 55% when the concentration of ASODN was 0.5 ?mol/L. The number of the cells treated with MUC2 ASODN was decreased as compared to the control cells. MUC2 ASODN transfection could inhibit the transition period of S phase to G2/M phase, and G2/M did not change much. The apoptosis rate was about 4.38%. As compared with blank control group, MUC2 ASODN could significantly inhibit MUC2 mRNA expression of SGC7901 cells. ASODN could downregulate the expression levels of MUC2 protein, MMP-2 and cathepsin D protein. Conclusion MUC2 ASODN transfection could specifically inhibit SGC7901 cells by downregulating the expression levels of proteolytic enzyme.
