Objective To explore the folate receptor mediated (FRD) check and multi-function acetic acid white solution liquid based cervical cytology (TCT) application value in cervical cancer screening.Methods A total of 602 cases of patients was tested with FRD multi-function acetic acid white solution check,and TCT and cervical biopsy pathology examination.With the used of histopathological results as the gold standard,FRD multi-function acetic acid white analysis was compared with the TCT screening inspection results.Results For a total 602 patients with TCT screening,the positive rate was 21.8％ (131/602),including 36 cases of CIN Ⅰ level,41 cases of CIN Ⅱ level,24 cases of CIN Ⅲ level,and 30 cases of cervical invasive carcinoma.For the FRD multifunction white acetate solution screening,its positive rate was 23.8％ (143/602).No statistically significant difference was found between TCT and FRD screening (P ＞ 0.05).The missed diagnosis rate of FRD multi-function white acetate solution screening was 2.6％ in inflammation,and 21.1％ in cervical invasive cancer,and 3.8 ％ in CIN.The missed diagnosis rate of TCT screening was 7.2％ in inflammation,5.3％ in CIN Ⅰ,4.9％ in CIN Ⅱ,and 58.6％ in CIN Ⅲ]; whereas,its detection coincidence rate was 100％ in squamous cells carcinoma (SCC) and adenocarcinoma (AC).FRD multi-function acetic acid white solution screening had a sensitivity 80.92％,specificity 92.14％,positive predictive value 74.13％,and negative predictive value 95.59％.TCT examination had a sensitivity 90.84％,specificity 90.23％,positive predictive value 72.12％,and negative predictive value 97.25％.No significant difference was found between FRD and TCT methods (P ＞ 0.05).Conclusions FRD and TCT methods were both efficient in screening and evaluation for cervical lesions and cervical cancer.Because FRD method is limited in the deep tube for examination of cervical lesions; it cannot completely replace the TCT examination.However,FRD method is reliable,economic,and simple operation; it is suitable for primary hospitals census of cervical cancer

Objective To investigate the biological significance of differentially expressed proteins from human primary lung adenocarcinoma with lymph node metastasis adenocarcinoma (LNM AdC) and without metastasis (non-LNM AdC) according to clinical diagnosis of lymph node metastasis and distant metastasis,with bioinformatics approach.Methods Cytoscape software was used to analyze a functional enrichment analysis and a protein-protein interaction network from differentially expressed proteins from LNM AdC and non-LNM AdC.Results The top biological processes were related to glucose catabolic process,hexose catabolic process,monosaccharide catabolic process,alcohol catabolic process,and cellular carbohydrate catabolic process.The top molecular functions were related to phospholipase inhibitor activity,lipase inhibitor activity,calcium-dependent phospholipid binding,phosphlipase A2 inhibitor activity,and lipid binding.A protein-protein interaction network of differentially expressed proteins was generated with literature data.Conclusions This bioinformatics analysis demonstrated that glucose catabolic process,alcohol catabolic process,calcium-dependent phospholipid binding,phosphlipase A2 inhibitor activity,ACTB,ANXA1,ANXA2,ANXA3,VCP,NPM1,KRT1,and SUMO4 are significantly associated with a lung adenocarcinoma.These network data provide new insights into the metastasis mechanisms of human lung adenocarcinoma.

Objectives To investigate the effect of electric vagal stimulation on the gene expression of injured myocardium from ischemia/reperfusion rat model and explore the involved molecular mechanism.Methods Twenty Sprague Dawley male rats were randomly selected and divided into 2 groups evenly:ischemia/reperfusion group (I/R group),and vagus nerve stimulation group (STM group).The left anterior descending coronary artery (LAD) was ligated and subjected to 30 min of myocardial ischemia followed by 2 h of reperfusion.In addition,10 min before reperfusion,left cervical vagus nerve of STM group was subjected to electronic stimulation at 5 V,2 ms and 1 Hz for 20 min.After 120 min of reperfusion,every group was randomly divided into two parts.One part that myocardium was collected from left ventricle was applied to determine the area of myocardial infarction.The RNA isolated from another part of the ischemic myocardium collected from left ventricle was hybridized to get gene expression profiles and the quality of hybridized RNA from both I/R and STM group was assessed and analyzed.GeneSpring software was applied to screen out the genes,which show significant difference between groups I/R and STM.Real-time polymerase chain reaction (RT-PCR) was applied to analyze the expression of important genes.Results (1)The area of myocardial infarction of STM (25.5 ± 3.9) ％ was significant reduced relative to L/R group (45.5 ± 4.8) ％ (P ＜ 0.05).(2)The expression levels of 186 genes were changed significantly,and analyzed by Gene ontology (GO) software,there were 3 kinds of genes were affected.The upregulated genes were reported to show protective effect on myocardium.The downregulated gene was relative to inflammation.(3)The RT-PCR result confirmed the genechip assay.Conclusions Electric vagal stimulation can reduce myocardial I/R injury in rats.Significant change of the gene expression was detected between groups I/R and STM.The results suggest that activation of cholinergic anti-inflammatory pathway be involved in the mechanism.

Objective To investigate the relationship between serum visfatin and glucose metabolism disorder in patients with polycystic ovary syndrome.Methods Seventy eight patients with polycystic ovary syndrome (PCOS) were selected,and,according to the results of glucose tolerance test and insulin release test (OGTT),were divided into normal OGTT without insulin resistance (NONIR) group (n =32 cases),OGTT normal with hyper insulinemia (HI) group (n =25 cases),and OGTT abnormalities that may be associated with hyper insulinemia (also known as abnormal glucose metabolism (AGM) group; n =21 cases).Sixteen cases of tubal infertility women were selected as control group in the same period.The relationship between serum visfatin and glucose metabolism was analyzed and related to various factors.The changes of relevant indicators of PCOS patients who were treated before and after treatment were observed in AGM group.Results In AGM Group,PCOS patient's menstrual cycle,testosterone (T),luteinizing hormone (LH)/follicle stimulating hormone (FSH),visfatin,triglyceride (TG),homeostasis model assessment of insulin resistance (HOMAIR) were higher than control group (P ＜ 0.05).The age at menarche,menstrual cycles,infertility time,waist-hip ratio (WHR),systolic blood pressure,T,estradiol (E2),and LH/FSH were no significant difference between AGM group versus NONIR group or HI group (P ＞0.05).However,the body mass index (BMI),waist circumference,diastolic blood pressure,HOMA-IR,and TG in AGM group were significantly higher than NONIR group,and older than HI group; visfatin in AGM group was higher than NONIR group or HI group (P ＜ 0.05).Visfatin was positively correlated with BMI,waist circumference,fasting insulin (FINS),fasting plasma glucose (FPG),HOMA-IR,and TG (r =0.423 ～ 0.847,P =0.01 ～ 0.04).After 3 months of treatment,8 cases AGM patients' serum visfatin,HOMA-IR,and blood pressure were significantly decreased (P ＜ 0.05).Conclusions High serum visfatin may be one predictor of glucose metabolism in patients with PCOS.Especially,the patients with obesity should be highly vigilant glucose metabolism disorder occurring and should be given positive joint programs treatment for weight control.

Objective To investigate efficacy and safety of photodynamic therapy on basal cell carcinomas.Methods Twenty three cases of basal cell carcinomas were given with photosensitizer 5-amino acid (ALA) ketone spreading on skin lesions.Reddish illumination was taken at 4h later with energy density at 100 J/cm2,40 min/time,and weekly for a total of 4 weeks; and 2 year followup in the study was evaluated recurrence retrospectively.Results Among twenty three patients with basal cell carcinomas,15 were cured(65.22％),5 partially (21.74％) remitted,and 3 ineffective (13.04％),with the efficiency 86.96％.None of the resolved lesions recurred during the 6-month follow-up period,and 3 cases were recurred within 1 year (20％).Repeated ALA-photodynamic therapy (PDT) treatment,recurred lesions were completely resolved.There were no additional recurrences after 2 year.ALA-PDT was well tolerated,and adverse effects were limited to mild local pain and erythema.Only three patients were complained of erythema and edema.Complete response rate was higher in younger patients (t =-2.94,P ＜0.01) and those with smaller lesions (t =-5.92,P ＜ 0.01).Superficial type had also significant higher response rate (x2 =27.17,P ＜ 0.01).Conclusions The application of photodynamic therapy in treatment of basal cell carcinoma is effective with less painfulness,non-invasiveness,and without side effect.It demonstrated a good efficacy and satisfactory cosmetic outcomes.

Objective To investigate the effects,mechanisms,and the optimum doses of Rosuvastatin and Losartan on expression of caveolin-1 in cultured human monocyte-macrophage cells which were induced by oxidized low density lipoprotein(ox-LDL).Methods Human-monocyte cells were separated and changed into the human monocyte-macrophage cells.The model of amerosclerosis was set up.These cells were incubated in different doses of Rosuvastatin(0.1,1.0,5.0 μmol/L) and Losartan (10,50,100 μmol/L),and then cultured in combination of two drags (5.0 μmol/L + 100 μmol/L).Expression of caveolin-1 mRNA was determined with real-time fluorescent quantitative polymerase chain reaction (RT-PCR).Results In ox-LDL group,caveolin-1 mRNA was decreased sharply relative to control group [(0.2533 ±0.00973) vs (0.9410 ±0.03677)] in a concentration-dependent manner (P ＜0.01).Compared to ox-LDL group,expressions of Caveolin-1 mRNA were increased gradually in different doses of Rosuvastatin alone and Losartan alone group [(0.5198 ± 0.04840),(0.6183 ± 0.06740),(0.7257 ± 0.03052) vs (0.2533 ± 0.00973) ; (0.3350 ± 0.04177),(0.4428 ± 0.03804),(0.6049 ± 0.02627) vs (0.2533 ± 0.00973)] in a concentration-dependent manner (P ＜ 0.01) ; the summit expressions of caveolin-1 mRNA were emerged in using Rosuvastatin and Losartan together (F =59.119,P ＜ 0.01).Conclusions Rosuvastatin and Losartan may be responsible for the expression of caveolin-1 in human monocyte-macrophage cells that were induced by ox-LDL.The expressions were up-regulated with dose dependent manner of these drugs,and got the crest stage when using optimum doses of Rosuvastatin and Losartan together.

Objective To investigate the effect of bisphosphonate medication (zoledronic acid,aclasta) on spinal fusion for osteoporotic patients through radiographic,clinical,and biological assessments.Methods A total of 79 patients with osteoporosis who were candidates for single-level posterior lumbar interbody fusion was randomly assigned to the experimental group (zoledronic acid injection,5mg,on the third day after surgery) or the control group (the same amount of saline injection,on the third day after surgery).Functional radiography and CT scans were used to evaluate fusion status.Bridging bone formation was graded into 3 categories:Grade A (bridging bone through bilateral vertebral),Grade B (bridging bone through a unilateral vertebral),or Grade C (incomplete bony bridging).The incidence of vertebral compression fractures occurring after surgery was assessed by means of MR imaging.A solid fusion was defined as less than 5° of angular motion in flexion-extension radiographs and the presence of Grade A or B bridging bone.Bone metabolic markers (β-C-terminal telopeptide of type Ⅰ collagen,β-CTX; and N-terminal propeptide of type Ⅰ collagen,PINP) were measured to investigate the biological effects of zoledronic acid on spinal fusion.Bone mineral density of femoral neck was measured by the dual X-ray absorptiometry.Clinical outcome was evaluated by means of the Oswestry Disability Index (ODI).Results Grade A or B bridging bone was more frequently observed in the experimental group at 3,6,and 9 months postoperatively (all P ＜ 0.05,respectively,Mann-Whitney U-test).At 12-months postoperative follow-up,bridging bone and solid fusion were not significantly different.No vertebral fractures were observed in the experimental group,whereas 6 patients in the control group showed vertebral compression fractures(P ＜ 0.05,Mann-Whitney U-test).Biochemical analysis of bone turnover demonstrated that zoledronic acid inhibited bone resorption from the early phase of the fusion process and also suppressed bone formation.Poor clinical results in the control group were demonstrated by ODI.Conclusions Osteoporosis patients undergoing spinal fusion who take bisphosphonates throughout the postoperative period was recommended.

Objective To investigate effect of FK506 binding protein 51 (FKBP51) on the c-JunN-terminal kinase (JNK) pathway in cerebral ischemia-reperfusion injury.Methods Transient global cerebral ischemia rat models were made by four-vessel method.Healthy male SD (Sprague Dawley) rats were randomly divided into:sham group,ischemia/reperfusion group (I/R group),FKBP51 antisense oligonucleotide group (FKBP51 ASODN group),FKBP51 missense oligonucleotide group (FKBP51 MSODN group),and solvent control group (TE group).The effect of FKBP51 ASODN on expression of FKBP51 protein and JNK was detected,and c-Jun phosphorylation was detected by Western blot.Results (1) FKBP51 protein expression in the FKBP51 ASODN group was reduced.The change of FKBP51 protein expression between the FKBP51 ASODN and sham groups was statistically significant (P ＜ 0.05).(2) The expression differences of total JNK protein between all the groups were not statistically significant (P ＞ 0.05).The expression of p-JNK in sham group was significantly less than the other groups (P ＜ 0.05).The expressions of p-JNK in I/R 3d,TE,and FKBP51 MSODN groups were higher relative to Sham group; however,the differences among those three groups were not statistically significant (P ＞ 0.05).The expression of p-JNK in FKBP51 ASODN group was significantly less than FKBP51 MSODN group (P ＜ 0.05).(3) The expression differences of total c-Jun protein among all groups were not statistically significant (P ＞ 0.05).The expression of p-c-Jun in sham group was significantly less than the other groups (P ＜ O.05).The expressions of p-c-Jun in I/R 6 h,TE,and FKBP51 MSODN groups were higher relative to the sham group; however,the differences among those three groups were not statistically significant (P ＞ 0.05).The expressions of p-c-Jun in FKBP51 ASODN group was significantly less than FKBP51 MSODN group (P ＜ 0.05).Conclusions FKBP51 might activate JNK signaling pathway in cerebral ischemia-reperfusion injury.

Objective To investigate cognitive functions in first-episode schizophrenia and unaffected first-degree relatives of different patients.Methods A total of 52 patients with first-episode schizophrenia (patient group),48 unaffected first-degree relatives of different patients (relatives group) and 50 healthy normal controls (control group) was recruited in the study.The attention,memory,and executive functions of all the subjects were assessed by a battery of neuropsychological tests,including cancellation test (CT),trail making test (TMT),digit span (DS),visual reproduction (VR),verbal fluency task (VFK),Wisconsin card sorting test (WCST) and HANOI tower.Results There were statistically significant difference among three groups in net scores of CT,TMTA,TMT-B,backward and total scores of DS,scores of VR,VFK,total errors and perseverate errors of WCST and all indicators of HANOI Tower (P ＜0.05 or P ＜ 0.01).Post Hoc multiple comparisons showed that,compared with the control group,the patient group had worse scores in all tests above except TMT-A in the relatives group (P ＜0.05 orP ＜0.01).However,compared with the patient group,the relatives group had better scores in net scores of CT,TMT-A,TMT-B,scores of VR,VFK,total errors and perseverate errors of WCST (P ＜ 0.05 or P ＜ 0.01).Conclusions Patients with first-episode schizophrenia have global cognitive functions deficits.Unaffected first-degree relatives of different patients also have cognitive deficits to a certain extent.Our study indicates that cognitive functions deficits may be viewed as a biomarker for candidates reflecting genetic liability for schizophrenia.
