Chinese Journal of Primary Medicine and Pharmacy 2014;21(8):1145-1147
Objective To discuss changes and curative effect of serum interleukin-2 and 6 and tumor necrosis factor-α (TNF-α) of burning mouth syndrome (BMS) patients before and after medical treatment.Methods 50 cases of BMS patients were selected as case group,and who were given Clonazepam tablets (2mg) and Fluoxetine capsules (20 mg) one time daily for 4 weeks.Observe and compare the changes of serum IL-2 and 6,and TNF-αof patients in two groups before and after 4 weeks' medical treatment,and proceeded with the clinical curative effect observation.Moreover,30 cases of healthy subjects who just took the physical examination in medical examination center(MEC) at that moment was the control group.Results The serum IL-2 and IL-6,and TNF-αlevels of patients in case group before medical treatment was obviously higher than those in control group (t =4.31,2.97,3.84,all P <0.01).After 4 weeks' medical treatment,serum IL-2 and IL-6,and TNF-αlevels of patients had obviously declined than before (t =2.88,2.34,3.21,P < 0.05 or P < 0.01).After 4 weeks' medical treatment,there were 6 cured cases,14 cases with significant effect,and 24 cases with curative effect,and the total clinical efficiency reaches 88.0% (44/50).Conclusion BMS patients have abnormal elevation of serum IL-2 and 6,and TNF-α,which may be the sensitive serological indicators of the early diagnosis of BMS.The changes of serum IL-2 and IL-6,and TNF-α levels may be the index of follow-up curative effect and prognosis observation.
2.Next-generation sequencing in molecular diagnosis of hereditary hearing loss.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(22):1815-1818
Next-generation sequencing (NGS) technologies have improved as well as the costs have gradually decreased in the detections of genetic diseases. This article describes the principle, platform, and data analysis of NGS and the application of NGS technologies to the molecular diagnosis of hereditary hearing loss (HL). The use of NGS technologies makes the discovery of HL genes more feasible than ever. And the data obtained by NGS used in genetic counseling for clinical practice may assist in defining genetic profiles of HL individuals and expedite the pace of personalized medical care.

Objective To evaluate the significance of tumor markers CEA and CA15-3,and biochemical markers of bone turnover (total procol]agen type Ⅰ amino-terminal propeptide (TP I NP),β-isomerized carboxyterminal propeptide (β-CTx),ALP and PTH) in the diagnosis of bone metastasis from breast cancer.Methods A total of 78 patients (all females) with mean age (56.72 ± 10.76) years,who were diagnosed with breast cancer,were included in this study.The patients were divided into two groups based on radionuclide bone imaging:with bone metastasis (n =32) and without bone metastasis (n =46).The serum concentrations of CEA,CA15-3,TP I NP,[β-CTx,PTH,ALP were measured.Gleason scores were evaluated.The diagnostic value was evaluated by ROC curve.The two groups were compared using two-sample t test.The correlations between bone metastasis and tumor markers,bone metastasis and biochemical markers of bone turnover were analyzed with Pearson correlation and logistic analysis.Results The serum levels of CEA,CA15-3,TPINP,β-CTx,PTH and ALP were significantly higher in the group with bone metastasis than those in the group without bone metastasis (t:4.16-7.56,all P < 0.05).For the diagnosis of bone metastasis from breast cancer,the AUC of CEA,CA15-3,TPINP,[β-CTx,PTH and ALP was 0.815,0.887,0.869,0.852,0.844,0.731,respectively.Using the cut-off values of 4.18 μg/L for CEA,0.04 U/L for CA15-3,49.70 μg/L for TP I NP,0.47 pg/L for β-CTx,54.90 ng/L for PTH and 49.90 U/L for ALP,the sensitivities were 56.3% (18/32),75.0% (24/32),78.1% (25/32),81.3% (26/32),78.1% (25/32),68.8% (22/32) and the specificities were 80.4% (37/46),84.8% (39/46),76.1% (35/46),78.3% (36/46),69.6% (32/46),58.7% (27/46),respectively.CEA,CA15-3,TPINP,β-CTx,PTH,ALP and Gleason score were positively correlated with the presence of bone metastasis (r:0.267-0.636,all P < 0.05).CEA,CA15-3,TP I NP,β-CTx,PTH and Gleason score were independent predictors for bone metastasis of breast cancer (odds ratios:2.45,3.44,1.24,1.54,1.11,2.22,all P <0.05).The total coincidence rate of regression model was 81.3% (26/32) in patients with bone metastasis.Conclusions The diagnostic values of CEA,CA15-3,TP I NP,β-CTx and PTH are comparable.Combined use of these parameters may be helpful for the early diagnosis of bone metastasis from breast cancer.

Objective To explore the effects of graphene oxide (GO)-polyethylene glycol (PEG)-folic acid (FA)-pyrenemethylamine hydrochloride (PyNH2)-mediated RNA interference (RNAi) of hypoxia-inducible factor-1α (HIF-1α) on the biological behaviors of human pancreatic cancer Patu8988 cells.Methods GO-PEG-FA-PyNH2 and RNAi targeting HIF-1α gene (GO-PEG-FA-PyNH2-HIF-1α-RNAi)was constructed.The expressions of HIF-1α and glucose transporter 1 (Glut-l) in Patu8988 cells were determined after knockdown of HIF-1α by RNAi.The invasive ability,the proliferation and the cell cycle of Patu8988 cells were investigated.The effect of HIF-1α knockdown on the uptake of 18F-fluorodeoxyglucose (FDG) in Patu8988 cells was also detected.Comparison of data was conducted by one-way analysis of variance and least significant difference t test.Results The GO-PEG-FA-PyNH2 was successfully constructed,and no cytotoxicity was found.Under the hypoxia or normoxia state,the mRNA and protein levels of HIF-1α and mRNA level of Glut-1 in cells transfected with GO-PEG-FA-PyNH2-HIF-1α-RNAi (study group) were lower than those in cells transfected with GO-PEG-FA-PyNH2 (negative group) and cells transfected with Opti-minimal essential medium (Opti-MEM,control group;F=30.25-32.58,t=3.66-5.81,all P<0.05);the numbers of migrated cells in the study group were much lower than those in the negative group and the control group (F=38.63 and 41.35,t=20.51-35.25,all P<0.01);the cell proliferation in the study group was significantly lower than that in the negative group and the control group (F=35.19 and 38.11,t =15.11-22.19,all P<0.05).The proportions of G0/G1 cells in the study group were higher than those in the negative group and the control group (F=34.60 and 34.83,t=11.55-34.56,all P<0.05);the 18 F-FDG uptake in the study group was lower than that in the negative group and control group (F=29.85 and 31.69,t =3.35-4.35,all P<0.05).Conclusion GO-PEG-FA-PyNH2-mediated HIF-1α RNAi inhibits the expression of HIF-1α in pancreatic cancer cells,leading to changes in related biological behaviors.
