Objective To compare the analgesic efficacy and side effects of patient-controlled intravenous analgesia (PCIA) with Lornoxicam and patient-controlled epidural analgesia(PCEA) with morphine in patients undergoing Orthopaedics surgery. Methods 100 ASA Ⅰ-Ⅱ Patients scheduled for Orthopaedic surgery were divided randomly into two groups: Lornoxicam PCIA group( n =50) , Lornoxicam 48mg was diluted to 100ml with normal saline (0.9%NS). Morphine PCEA group( n =50), Morphine 9mg + bupivacaine 150mg were diluted to 100ml with normal saline (0.9%NS) .In both groups the patients were received PCA at a rate of 2ml/h with the bolus dose of 0.5ml and lockout interval of 15min. The loading dose was Lornoxicam 8mg plus Ondansetron 4mg in group PCIA and morphine 1mg and Ondansetron 4mg diluted to 10ml with normal saline (0.9%NS) in group PCEA 30 minutes before the end of operation. BP, RR, ECG, SpO_2 were monitored continuously after operation. Efficacy of analgesia was assessed by VAS scores. Side effects such as drowsiness, sweat, nausea, vomiting and skin pruritus were also observed. Results There was no significant difference in the mean VAS score between group PCIA and group PCEA at 4h, 8h, 16h ,20h, 24h, 32h and 48h. after operation. There was no significant difference in side effects between the two groups except the occurrence of sweat, nausea, vomiting and skin pruritus which was lower in group PCIA than in group PCEA ( P

Objective To determine the effects of hypoxia inducible factor-1α(HIF-1α) expression on postoperative adjuvant radiotherapy in esophageal carcinoma. Methods 95 cases with esophageal carcinoms who received radical operation were analyzed with followed-up data from 1995 to 1998.Expression of HIF-1α in 45 patients with esophageal carcinoma who received radiotherapy after radical operation were deternlined by immunohistochemical method in contrast with 50 patients with esophageal carcinoma received surgery alone.Kaplan-Meier method and COX proportional hazard model were used to analyze.Results The positive expression of HIF-1α in esophageal carcinoma was observed mainly in the nucleus of tumor cells.The positive expression rate of HIF-1α in esophageal carcinoma was 58.9%.The expression of HIF-1α had no relationship with age,sex,histologic subtype and T stage,but had positive relationship with recurrence and distant metastasis.There was significant difference between patients with positive and negative HIF-1α protein expression in surgery alone and postoperation radiotherapy group. COX model analysis showed that HIF-1α had separate and significant impacts on prognosis in surgery group and surgery plus radiotherapy group. Conclusion Over expression of HIF-1α protein suggests a poor prognosis,and has tendency to resist radiotherapy in esophageal carcinoma.

Objective:To investigate the correlation of sleep disorders(SD)with serum levels of amyloid β-proteins(Aβ 1-42)and tau phosphorylated at threonine(P-Tau 181)in patients with Alzheimer's disease(AD). Methods:A total of 126 patients with mild and moderate AD who met the inclusion criteria in the memory clinic, sleep clinic and geriatrics department of Jianghan Oilfield General Hospital affiliated to Yangtze University from February 2017 to January 2020 were included.The Pittsburgh Sleep Quality Index(PSQI)was used to evaluate sleep quality.Patients with PSQI scores ≥7 were included in the AD group with sleep disorders(AD-SD group), and patients with PSQI scores <7 were included in the AD group without sleep disorders(AD-NSD group). The Montreal Cognitive Assessment(MoCA), Global Deterioration Scale(GDS), Clinical Dementia Rating(CDR), Hamilton Rating Scale for Depression(HRSD)and Hamilton Anxiety Rating Scale(HAM-A)were used to evaluate cognitive and psychosocial symptoms.During the same time, biological markers such as serum Aβ 1-42, Aβ 1-40 and P-Tau 181 were detected by using enzyme-linked immunosorbent assays.Patients in the two groups received donepezil as an anti-dementia therapy, while the AD-SD group was treated additionally with a targeted sleep intervention.All patients underwent neuropsychological assessment and biochemical tests at enrollment and at the end of the 6th month, and results from all parameters at baseline and at the end of the 6th month were compared.At the end of the six-month treatment, patients in the AD-SD group were further divided into the recovery AD-SD sub-group and the no-recovery AD-SD sub-group based on the extent of sleep improvement. Results:Of the 126 AD patients, 93(73.8%)had sleep disorders.There was no statistically significant difference between the two groups in gender, age, onset age, educational level, course of disease, CDR, GDS, MoCA, Aβ 1-40 or Aβ 1-42/Aβ 1-40(all P>0.05). The scores of PSQI, HRSD and HAM-A and serum levels of Aβ 1-42 and p-Tau 181 showed statistically significant differences between the AD-ND and AD-NSD groups( P<0.05 or P<0.01). At the end of the 6th month, the scores of PSQI, GDS, HRSD and HAM-A and levels of Aβ 1-42, Aβ 1-40, and P-Tau 181 also showed statistically significant differences between the AD-ND and AD-NSD groups( P<0.05 or P<0.01). There was no statistically significant difference in results from other parameters( P>0.05). Spearman correlation analysis showed that PSQI was correlated with HRSD( r=0.271, P=0.009), HAM-A( r=0.479, P=0.000), Aβ 1-42( r=0.470, P=0.000), Aβ 1-42/ Aβ 1-40( r=0.479, P=0.000)and P-Tau 181( r=0.371, P=0.000)in the AD-SD group at baseline.Multivariate Logistic regression model showed that serum Aβ 1-42 and P-Tau 181 levels and HRSD had predictive effects on changes in sleep quality in AD patients( OR=1.897, 1.269 and 1.889, P=0.000, 0.003 and 0.000). The areas under the receiver operating characteristic(ROC)curves for Aβ 1-42, P-Tau 181 and HRSD were 0.926(95% CI: 0.860-0.991), 0.837(95% CI: 0.746-0.927)and 0.854(95% CI: 0.776-0.932), respectively. Conclusions:Sleep quality is correlated with serum Aβ 1-42and P-Tau 181 levels in AD patients.Elevated serum levels of Aβ 1-42 and P-Tau 181 and high HRSD scores are important predictors of SD in AD patients and may be used as indexes for clinical treatment efficacy.

Objective:To observe the value of heart-type fatty acid-binding protein (H-FABP) and echocardiographic indexes in the diagnosis of cardiac insufficiency in sepsis.Methods:A prospective observational study was conducted. Eighty patients with sepsis admitted to the department of critical care medicine of the First Affiliated Hospital of Medical College of Shihezi University from October 2016 to January 2018 were enrolled. General clinical data such as gender, age, acute physiology and chronic health evaluationⅡ(APACHEⅡ), sequential organ failure assessment (SOFA) score, hospitalization time and 28-day mortality were recorded. Echocardiographic indexes at 1, 3, 7, 10 days after diagnosis, and white blood cell (WBC), neutrophilic granulocyte percentage (N%), N-terminal pro-brain natriuretic peptide (NT-proBNP), serum H-FABP level were recorded. Sepsis patients were divided into normal cardiac function group ( n = 30) and cardiac insufficiency group ( n = 50) according to cardiac function, the differences of echocardiographic indexes and cardiac markers between the two groups at different time points were compared. Logistic regression was used to screen out cardiac ultrasound indexes and cardiac markers that affect the occurrence of cardiac dysfunction in sepsis patients, and then receiver operating characteristic (ROC) curve analysis was performed. Results:Comparing the general data of the two groups, only the SOFA score of the cardiac insufficiency group was significantly higher than that of the normal cardiac function group (6.12±4.09 vs. 4.57±2.45, P < 0.05). N% and H-FABP in cardiac insufficiency group were higher than those in normal cardiac function group at the same time (N%: F = 6.973, P = 0.010; H-FABP: F = 17.303, P = 0.000). Without considering the time factor, there were significant differences in left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), stroke volume (SV), cardiac output (CO), left ventricular fractional shortening (LVFS), E-point of septal separation (EPSS), isovolumic relaxation time (IVRT), E peak deceleration time (EDT), A peak duration (Ad), left ventricular systolic pulmonary vein velocity (S), blood flow velocity of pulmonary vein in early left ventricular diastolic period (D), tricuspid orifice early diastolic blood flow velocity (E'), tricuspid orifice late diastolic blood flow velocity (A'), systolic velocities of the right ventricular free wall tricuspid annulus (Sm), and pulmonary valve annulus blood flow velocity (PVBV) between the two groups. ROC curve analysis of cardiac ultrasound indicators and cardiac markers screened by Logistic regression showed that the area under ROC curve (AUC) and the positive and negative predictive values were: LVEDV was 0.636, 77.30%, 56.03%; SV was 0.779, 88.82%, 71.19%; LVEF was 0.753, 92.12%, 55.21%; CO was 0.754, 88.82%, 77.19%; LVFS was 0.728, 81.25%, 66.99%; EPSS was 0.663, 96.99%, 51.56%; IVRT was 0.775, 86.97%, 73.55%; A' was 0.908, 96.58%, 89.60%; Sm was 0.738, 93.37%, 56.77%; H-FABP was 0.673, 80.26%, 57.25%, respectively. H-FABP was tested in parallel with LVEDV, SV, LVEF, CO, LVFS, EPSS, IVRT, A', Sm, and the positive predictive values were higher than the single diagnostic test (85.45%, 93.91%, 96.72%, 94.74%, 89.43%, 98.00%, 92.00%, 99.42%, 93.60%, respectively), the negative predictive values were lower than the single diagnostic test (50.89%, 57.93%, 49.15%, 58.18%, 57.05%, 45.74%, 57.92%, 64.13%, 47.78%, respectively). Conclusion:Cardiac ultrasound indicators LVEDV, SV, LVEF, CO, LVFS, EPSS, IVRT, A', and Sm combined with H-FABP are of certain value in the diagnosis of sepsis-associated heart dysfunction.

Objective:
To observe the effect of transforming growth factor-β1 (TGF-β1) on the migration of oral carcinoma associated fibroblasts (CAFs) with two-dimensional culture model and three-dimensional model.
Methods :
Under two-dimensional culture conditions, CAFs stimulated by TGF-β1 with the addition of 10 ng/mL medium were used as the experimental group, and untreated CAFs were used as the control group. The migration of CAFs with the stimulation of TGF-β1 was measured by cell scratch assay and transwell assay. CAFs positive for green fluorescent protein (GFP) were cultured by retrovirus transfection. Human tongue squamous cell carcinoma cells SCC25, GFP(+) CAFs and CAFs with three-dimensional cell co-culture models were established. The three-dimensional model cultured under the stimulation of TGF-β1 with 10 ng/mL medium was used as the experimental group, and the three-dimensional model without TGF-β1 was used as the control group. The migration of CAFs with the stimulation of TGF-β1 was also measured by the three-dimensional models.
Results:
It was verified that 10 ng/mL TGF-β1 promoted the migration of CAFs in the two-dimensional culture model. The three-dimensional co-culture models of SCC25, GFP(+) CAFs and CAFs were successfully established. The migration of SCC25 and CAFs was detected in the three-dimensional model. However, 10 ng/mL TGF-β1 had little effect on their migration.
Conclusion
The effect of TGF-β1 in vitro on the migration of oral CAFs was associated with different culture models in two and three dimensions.
