Objective To explore the relations of the doctor-patient relationship to psychological security and stress.Methods Totally 430 operation patients were selected and followed-up.A survey was performed using the Security Questionnaire (SQ),the Patient Doctor Relationship Questionnaire 13-Item Version (PDRQ-13),the Hospital Stress Rating Scale (HSRS) Results The average score of SQ was lower than medium value in operation patients.The SQ scores of operation patients with emergency operation were 39.50±10.51,lower than those of selective operation which were 49.02±10.37 and limited operation which were 47.67±10.29 (P ＜ 0.05).The SQ scores of operation patients who didn't provided themselves were 37.33±10.10,lower than those of basically which were 40.10±10.83 and partly provided for themselves which were 43.50±10.51 (P＜ 0.05).The SQ scores of operation patients in severe group according severity of illness were 37.13±10.40,lower than those of them in mild group which were 39.19±10.24 and moderate group which were 41.38±10.01 (P＜ 0.01).The SQ scores of post-operation patients were 44.32±9.96,higher than post-operation patients which were 40.36±10.81 (P ＜ 0.01).The lack of comforts (LC),lack of information (LI) and risks of serious disease (RSD) scores of post-operation patients were 49.23±30.62,30.46±21.42,52.84±31.22,lower than those of post-operation patients which were 52.37±32.06,35.25±20.14,80.12±33.18 (P ＜ 0.05).The path analysis showed that the regression relationship between SQ scores and PDRQ scores,RSD scores was established (β=0.40,-0.26,P ＜ 0.01),and the PDRQ-13 scores was a mediator between the scores of LC,LI,RSD and the SQ scores (β=0.40,P＜0.01).The PDRQ-13 scores was a adjustor between the RSD scores and the SQ scores (β=-0.34,P ＜ 0.01).Conclusions The operation patients have a low level of the sense of security which is statistically significant with surgical types,the ability to care for themselves and severity of illness.The sense of security of post-operation patients were higher than those of pre-operation patients.The recognition of physician-patient relationship may be play a mediating and adjusting role between the sense of security and stress.The surgical stress affect patient security and physician-patient relationship.

Objective TO evaluate the efficacy and safety of three adjuvant chemotherapy regimens after curative resection for stage III colorectal cancer,and present clinical evidence for proper choice.Methods 256 cases with stage Ⅲ colorectal cancer randomized to receive de Gramont,modified FOLFOX4(mFOLFOX4) and XELOX regimens.3-year disease-free survival(DFS) and overall survival(OS) were compared within the three groups and subgroups.Therapeutic adverse events were recorded and analyzed with Kaplan-Meier.Results Compared with de Gramont regimen,mFOLFOX4 and XELOX had superior efficacy.The two former could significantly improve 3-year DFS(79.7% vs.66.2%,P=0.015;81.5% vs.66.2%,P=0.004) and medium survival time(40.2 mon vs.37.8 mon,P=0.024;41.4 mon vs.37.8 mon,P=0.014).Meanwhile they could respectively decrease the ratio of recurrence risk 18%(P=0.024) and 21%(P=0.003).The relative benefit of mFOLFOX4 versus XELOX didn't differ for 3-year DFS [hazard ratio(HR): 0.84,95% confidence interval(CI): 0.79～1.12,P=0.13] and OS(HR: 0.87,95%CI: 0.84~1.06,P=0.54).In advanced analysis of DFS in subgroup,XELOX had better trend of survival advantage.mFOLFOX4 had higher adverse events within these regimens,especially in grade 3 or 4 neutropenia and peripheral neurologic adverse events.Conclusion XELOX maintains its efficacy and safety ratio in advanced colorectal cancer.Patients have good tolerance and compliance.The regiment is deserved to be applied in clinic.

Objective To analyze expression of interleukin (IL)-23p19 and IL-23 receptor (IL-23R) in inflammatory bowel disease (IBD),and the role in the induction of peripheral blood T cell activation and proinflammatory cytokine secretion.Methods Peripheral blood (PB) and intestinal mueosal biopsies were collected from 12 patients with Crohn's disease (CD),25 patients with ulcerative colitis (UC) and 20 healthy controls.Expression of IL-23p19 was determined by immunohistochemistry and RT-PCR.IL-23R expression in CD4+,CD8+ T and NK cells from peripheral blood and lamina propria was analyzed by flow eytometry.Peripheral blood mononuclear ceils (PBMC) were isolated and cultured under stimulation with IL-23 and anti-CD3,and the levels of tumor necrosis factor α (TNFα) interferon (IFN)γ and IL-2 were determined by enzyme-linked immunosorbent assay (ELISA).Results The expression of II.-23p19 was significantly increased in inflamed mucosa of CD at both the transcriptional and translational levels compared with that in UC and healthy controls.IL-23R was mainly expressed in PB- and lamina propria-CD4+,CD8+T cells and NK cells from IBD patients,and markedly increased compared with controls (P＜0.05).IL-23 strongly triggered PBMC from IBD patients to produce significantly higher levels of IFN-γ,TNF-α and IL-2(P＜0.05).Conclusions IL-23p19 and IL-23R are highly expressed in IBD,particularly in CD,and may play an important role in the induction of T cell activation and proinflammatory cytokine secretion,suggesting that targeted therapy directed against IL-23 may have a therapeutic role in IBD.

ObjectiveTo analyze the characteristic of the T peak-end interval (Tpe) in dilated cardiomyopathy(DCM) patients with heart failure and its significance in evaluation of global dispersion of ventricular repolarization.MethodsFifty-three inpatients were enrolled in this study,which included 28patients with DCM and heart failure (DCM group),and 25 patients with supraventricular tachycardia and without structural heart disease (control group).The Tpe and the dispersion of QT interval (QTd) from the 12-lead surface electrocardiogram(ECG) were acquired and measured,and consequently the corrected numerals of the average of Tpe (Tpe-AVEC),the maximal Tpe (Tpe-MAXC) were acquired.ResultsThe levels of Tpe-AVEC,Tpe-MAXC and QTd in DCM group were significantly higher than those in control group [ ( 106.31 ±26.34) ms vs.(82.72 ± 10.01 ) ms,(234.05 ± 69.75) ms vs.( 119.15 ± 11.55 ) ms,( 119.17 ± 67.62) ms vs.( 39.74 ± 17.04 ) ms ] ( P ＜ 0.05 or ＜ 0.01 ).ConclusionsThe global dispersion of ventricular repolarization is significantly increased in patients with DCM and heart failure.The Tpe-AVEC and Tpe-MAxc are recommended to be used for evaluating the dispersion of ventricular repolarization as the prognostic index in patients with DCM and heart failure.

A rapid method was developed for the determination of 5 common fatty acids, palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid in industrial oleic acid based on ultra_performance convergence chromatography_mass spectrometry ( UPC_MS) . The sample was dissolved by n_hexane, followed by clean_up of extract using 0. 22 μm organic phase filter. The fatty acids were separated in 3 min on the column of Acquity UPC2 BEH 2_EP by gradient elution with carbon dioxide and methanol/acetonitrile (1∶1, V/V) system, and finally detected by MS detector in ESI- mode. Through the optimization of UPC2_MS condition, the reasonable linearity was achieved for all the analytes over the range of 0. 5-100 mg/L with the correlation coefficients ( R2 ) greater than 0. 9985. The recoveries for five fatty acids at three spiked levels were in the range from 89 . 3% to 106 . 67% with relative standard deviations of 0 . 8%-3 . 0%. The limits of detection for target compounds in the method ranged from 0. 07 mg/L to 0. 26 mg/L. The real sample analysis showed that this method was simple,fast and had a good separation effect. There was no need of derivatization for fatty acid samples. This work would provide a fast and effective detection method for UPC2 technology in oil related research field.

Osteosarcoma is a common primary malignant bone tumor with highly aggressive and distal metastasis and poor prognosis. Abnormal metabolism of iron, an essential nutrient with electron-exchange capacity and an important participant in cellular activities, is closely associated with the progression of osteosarcoma. Ferroptosis has been shown to regulate osteosarcoma progression and play an important role in the treatment of osteosarcoma. Exploring the application of relevant molecular mechanisms of ferroptosis in osteosarcoma and the current status of pharmacological intervention may provide new strategies for the treatment of osteosarcoma.

Objective A prospective cohort study was carried out to assess the mortality and potential risk factors for primary liver cancer (PLC) in Haimen city of Jiangsu province.Methods The cohort involved 89 789 adult residents aged 25-69 years.Upon the entry of this project,each subject was asked to complete a questionnaire and to provide a blood sample of 10 ml.Surface antigen of hepatitis B virus (HBsAg) was tested by radioimmunoassay.All the subjects were followed-up every year for vital statistics and death certificate information until 2014.Cox proportional hazard model was used to estimate the hazard ratio (HR) and 95％ confidence interval (95％ CI) for PLC mortality associated with HBsAg status and other risk factors.Results During the 1 299 611 person-years of follow-up,a total of 2 583 PLC cases were identified,including 2 149 men and 434 women.Mortality of the PLC for men and women were 247.80/100 000 person-years and 100.38/100000 person-years,respectively.Among those who died of PLC,73.87％ had been tested HBsAg positive.HBV infection seemed the predominant risk factor for PLC and the HRs were 15.97 for men (95％CI:14.29-17.85) and 21.63 for women (95％CI:16.16-28.96) respectively.Ageing,cigarette smoking,previous history of hepatitis,and family history of HCC were factors associated with the increased risk for PLC.Conclusion People living in Haimen city had a high risk on PLC.HBV infection appeared the most important risk factor for HCC mortality in this area.
