Objective:To observe the influence of SBAR communication mode on the condition of patients undergoing thoracolaparoscopic combined with esophageal cancer resection.Methods:A total of 200 patients who were admitted to the Department of Gastroenterology and Oncology from October 2017 to October 2019 in Affiliated Hospital of Southwest Medical University were selected for elective thoracolaparoscopic combined with esophageal cancer resection. According to the random number method, they were divided into 100 cases in the control group and the SBAR group. The control group used conventional preoperative communication visit mode, and the SBAR group used SBAR communication mode and preoperative visit based on the control group. The following items such as the preoperative negative mentality scores, quality of life score, postoperative complications and nursing satisfaction rate of the two groups before and after nursing interventionwere compared.Results:Before the intervention, the difference of the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores of the two groups was not statistically significant ( P>0.05). After the intervention, the SAS and SDS scores of the two groups were 49.32±4.96, 55.95±5.32, 50.93±4.74, and 56.33±5.89, respectively, which were significantly reduced. The SDS and SAS scores of the SBAR group were lower than those of the control group ( t values were -9.115 and -7.142, P<0.001). The difference of the World Health Organization Brief Table on Quality of Life (WHOQOL-BREF) scores of the two groups before the intervention was not statistically significant ( P>0.05). After the intervention, the WHOQOL-BREF scores of the two groups were 12.27±1.39 vs. 9.18±1.24, 16.13±1.51 vs. 12.48±1.22, 16.13±1.95 vs. 12.71±1.28, 15.09±1.81 vs. 13.08±1.48, 18.11±1.82 vs. 13.51±1.47, 14.09±1.61 vs. 12.98±1.28. The scores of the SBAR group were higher than those of the control group ( t values were 5.397-19.662, P<0.001). The postoperative complications rate of the SBAR group was 3.00% (3/100), which was less than 18.00% (18/100) of the control group ( χ 2 value was 11.971, P<0.001). The overall satisfaction rate of patients in the SBAR group with care was 100.00% (100/100), which was higher than the 84.00% (100/100) in the control group ( χ 2 value was 17.391, P<0.001). Conclusions:In patients with esophageal cancer undergoing thoracic laparoscopy combined with esophageal cancer resection, the use of SBAR communication mode for the patient′s preoperative visit can significantly reduce the patient′s preoperative anxiety and depression negative scores and improve the patient′s quality of life, reduce the occurrence of postoperative complications, improve patient satisfaction with nursing with ideal effect.

To observe the histopathological changes of mice experimentally infected with plerocercoid,mice were infected orally by plerocercoids that were collected from Rana nigromaculatus (5 strips/mouse),and were killed 2-10 weeks later to undergo the histopathological observation.Plerocercoids were found in the skin,muscle,liver,lung cavity of mice.There were diffuse congested spots and capsule formation ;the fat tissue showed severe degeneration and necrosis.In the fibrous tissues ,moderate proliferation of the enveloping adipose tissue was demonstrated.In addition,a large number of acute and chronic inflammatory cell infiltration and abscess formation could be found.It is evident that the plerocercoids parasitize mainly in the subcutaneous tissues and muscles of mice.and mice experimentally infected with plerocercoids show different degree of histopathological changes.

BACKGROUND:The research at home and abroad for appropriate immature myocardial cardioplegia has no breakthrough, and it may be a better mean to improve the protection effect of existing cardioplegia on immature myocardial by adding ingredients. Adenosine can reduce ischemia and neutrophil-mediated reperfusion injury, and salvia miltiorrhiza can reduce the content of ischemic myocardial lipid peroxide and increase the scavenging of myocardial cells to oxygen radical. OBJECTIVE:To investigate the protection effect of improved myocardial protection fluid containing adenosine and salvia miltiorrhiza on the heart, liver and kidney. METHODS:Sixty cases of infant open heart operation of the first time were randomly divided into three groups, 20 cases in each group. The adenosine group received the improved myocardial protection fluid added with adenosine, the combination group received the improved myocardial protection fluid added with adenosine and miltiorrhiza salvia, and the control group received the improved myocardial protection fluid in the same volume. The blood samples were taken at the time before anesthesia induction, 30 minutes after cardio pulmonary bypass beginning, 1 hour after cardio pulmonary bypass end and 24 hours after cardio pulmonary bypass end. The serum levels of the creatine kinase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine, tumor necrosis factor-α, interleukin-6, interleukin-8 and interleukin 10 were detected. RESULTS AND CONCLUSION:The serum levels of the alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and creatine kinase in three groups were increased, but the control group was increased significantly (P<0.01), and there were significant differences between adenosine group and combination group (P<0.05);the levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 were significantly increased after operation (P<0.05). The levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 in the control group were significantly higher than those in the adenosine group and combination group before induction and at the same time point (P<0.01);at 3 minutes and 24 hours after cardio pulmonary bypass, the level of interleukin-10 was increased in three groups, but the level of interleukin-10 in the adenosine group was significantly higher than that in the control group (P<0.01). The results indicate that improved myocardial protection fluid has great protection effect on immature myocardial, and can significantly reduce the serum levels of tumor necrosis factor-α, interleukin-6 and interleukin-8, promote the secretion of interleukin-10 that can inhibit inflammatory cytokine and can significantly reduce the inflammatory response caused by cardiopulmonary bypass. So the improved myocardial protection fluid has protection effect on important organs, such as heart, lung, liver and kidney.

Objective To investgate the value of various parameters obtained from monoexponential, biexponential, and stretched exponential diffusion?weighted imaging models in the differential diagnosis of breast lesions. Methods A retrospective study performed in 54 patients with pathologically confirmed malignant tumors(n=30), benign lesions(n=34) and normal fibroglandular tissues (n=30). All patients underwent T1WI, T2WI, dynamic enhancement and diffusion weighted MRI with multi?b values at a 3.0 T magnetic resonance imaging unit. All parameters were measured at a workstation. ADC was calculated by using monoexponential analysis(b=0, 800 s/mm2). Slow apparent diffusion coefficient (ADC?slow), fast apparent diffusion coefficient (ADC?fast), and perfusion fraction (f) were calculated using the biexponential model. Distributed diffusion coefficient (DDC) and water molecular diffusion heterogeneity index (α) were obtained from diffusion?weighted images using the stretched exponential model. All parameters were statistically compared among normal fibroglandular tissues, benign lesions and malignant tumors using Kruskal?Wallis rank sum test. Mann?Whitney U test were used for further comparisons between specific group pairs. ADC values were compared with ADC?slow and DDC for different groups by paired Wilcoxon test. Correlations between ADC?value, ADC?slow and DDC were assessed by using Spearman rank correlation coefficient. Receiver operating characteristic curve was used to analyze and compare the ability of these parameters in differentiation of benign and malignant breast lesions. Results The ADC, ADC?slow, f, DDC and α values were significantly different among the normal fibroglandular tissues, benign tumors and malignant tumors (P<0.05). Further differential comparisons of the four parameters between each pair showed that the ADC, ADC?slow, f, DDC and α values were significantly lower in malignant tumors than both in normal fibroglandular tissues and benign tumors(P<0.016 7). The ADC values of normal fibroglandular tissues, benign tumors and malignant tumors were significantly higher than ADC?slow and DDC (P<0.05). The f and DDC had higher area under the receiver operating characteristic curve (0.688 and 0.657 respectively). The optimal cutoff values for ADC, ADC?slow, f, DDC and α were 1.235 × 10-3mm2/s, 0.428 × 10-3mm2/s, 57.8%, 1.175 × 10-3mm2/s and 0.721, respectively. Theαvalue showed higher specificity (65.5%) and the f value had higher sensitivity (82.9%). Conclusion The parameters derived from biexponential and stretched exponential DWI could be helpful for differentiation between benign and malignant breast tumors.

Objective To analyze the levels of T helper(Th)17-related cytokines interleukin(IL)-17,IL-22,IL-23 and IL-27 in plasma of patients with systemic lupus erythematosus(SLE).Methods Plasma IL-17,IL-22,IL-23 and IL-27 levels were measured by enzyme-linked immunosorbent assay in 45SLE patients and 32 healthy controls and their associations with each other,disease activity and clinical features were evaluated.Results Plasma levels of IL-17 and IL-23 were significantly higher in SLE patients than in controls[77.8(25.4～487.6)pg/ml vs 36.4(15.7～338.2)pg/ml;14.7(<7.8～247.5) pg/ml vs <7.8(<7.8～81.7)pg/ml.both P<0.01].with no difference between active and inactive disease.In contrast,IL-22 levels were markedly decreased in SLE patients compared with the controls[77.4(<15.6～559.7)pg/ml vs 378.8(21.8～1154.2)pg/ml,P<0.01]and were lower in active disease than in inactive disease(P<0.01).IL-27 levels tended to be higher in SLE patients compared with controls,but the difference was not significant (P>0.05).A strong and positive correlation was found between IL-17 and IL-23 levels(P<0.01)in SLE patients.IL-22 levels were negatively correlated with SLEDAI score,erythrocyte sedimentation rate and antidsDNA antibody titers(all P<0.01),and positively correlated with C3 levels (P<0.05).Each cytokine levels were not related to specific manifestations and treatments.Conclusion Th17 cytokine response in peripheral blood of patients with SLE is abnormal.and IL-17 and IL-22 appear to play different roles in SLE pathophysiology.IL-23/IL-27 imbalance may contribute to the development of Th17-mediated inflammation in SLE.

Objective To compare the initial detection rate and the accuracy of qualitative diagnosis of multislice spiral computed tomography (MSCT),gastrointestinal tract radiography,gastroscopy,and endoscopic ultrasonography in the diagnosis of gastric lipoma,with a focus on evaluating the diagnostic value of MSCT.Methods Twenty-six patients with gastric lipoma,6 males and 20 females with a mean age of 61 years (ranging from 41 to 82 years) and confirmed by pathology,were enrolled in the present study.Their clinical,pathologic and imaging findings were retrospectively analyzed.All the patients underwent gastroscopy,and plain and dynamic enhanced MDCT scans.Of them 21 cases underwent endoscopic ultrasonography and 12 cases gastrointestinal tract radiography.Results The detection rate was 88.5％(23/26) and 80.8％(21/26),P＞0.05 for MSCT and gastroscopy,respectively,in the initial diagnosis of gastric lipomas,both higher than that of gastrointestinal tract radiography (41.7％,5/12).The accuracy of qualitative diagnosis of MSCT (100％,23/23) was higher than that of endoscopic ultrasonography (71.4％,15/21),gastrointestinal tract radiography (0％,0/5) and gastroscopy (0％,0/21).The lesions located at the gastric antrum in 18 cases (69.2％,including 10 front wall,6 posterior wall and 2 pyloric canal),the gastric body in 7 cases (26.9％) and the gastric fundus in 1 case (3.8％).All the lipomas presented as round or ovoid nodule with clear boundary on MSCT images,and homogeneous or mixed low density.The CT values,long dimensions and volumes ranged from-50 to-95Hu (mean-72.58Hu),5.7 to 40.7mm (mean 17.67mm) and 0.02 to 7.03cm3 (mean 1.89cm3),respectively.Contrast-enhanced CT scans showed no enhancement in all the lesions.Conclusion MSCT can make accurate locating and qualitative diagnosis for gastric lipomas.

Objective To investigate the different radioprotective effects of total flavonoids of Astragalus (TFA) on human normal mesenchymal stem cells(hMSCs) and hepatoma cells injured by 60 Coγ-ray radiation.Methods hMSCs and HepG-2 cells were cultured and randomly divided into TFA-treated and untreated groups.The cells of different groups were irradiated with 60 Co γ-rays at the dose of 6 Gy.MTT method was utilized to detect the survival rates of the hMSCs and HepG-2 cells pretreated or untreated with TFA before irradiation.Cell clone formation test was used to measure the cellular radiosensitivity.The apoptosis rates of different groups were determined by flow cytometer assay.The expression rates of the apoptosis-promoting proteins Fas and Bax and the apoptosis-inhibiting protein Bcl-2 were analyzed by Western blotting.Results MTT showed that the survival rates of hMSCs pretreated by TFA were 1.15-1.95 times higher than that of the pure irradiation group.On the contrary,the survival rates of the TFA pretreated HepG-2 cells were only 0.53-0.23 times that of the pure irradiation group.There was a good dose-effect relationship between the cell survival rate and the TFA concentration.Cell clone formation rate indicated that combined treatment of TFA and radiation inhibited the cell proliferation more effectively than single TFA or pure radiation.Flow cytometry showed that 6,24 and,48 h post-irradiation to 6 Gy,the apoptosis rates of the hMSCs were 23.3% ,11.2% ,and 2.9% ,respectively in the TFA pretreated group and were 29.3% ,24.9% ,and 13.6% in the pure radiation group.However,the apoptosis rates of the HepG-2 cells at 6,24,and 48 h post-irradiation to 6 Gy were 11.6% ,17.3% ,and 20.1% ,respectively in the TFA pretreated group and were 6.9% ,9.3% ,and 15.8% ,respectively in the direct radiation group.Western blotting showed that the expression levels of Fas and Bax proteins in the HepG-2 cells were significantly higher in the TFA pretreated group than in the pure radiation group.On the contrary,the expression level of the apoptosis inhibiting protein Bcl-2 was significantly lower in the TFA pretreated group than in the pure radiation group.Conclusions TFA has obvious effects of radiological protection on human hMSCs and has no effects of radiological protection but effects of apoptosis enhancement on hepatoma cells.The promotion of apoptosis of TFA on hepatoma cells is primarily through increasing the expression of apoptotic proteins such as Fas and Bax and reducing the expression of anti-apoptotic protein Bcl-2.

OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.

METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.

RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).

CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

Aim To determine whether AngⅡin para-ventricular nucleus (PVN)was involved in the chronic intermittent hypoxia (CIH ) induced-hypertension in rats.Methods Male Sprague-Dawley rats were ran-domly divided into Sham and CIH groups,the Sham rats were exposed to continuous normoxia,while the CIH rats were submitted to CIH (8 h per day for 15 days).The conscious noninvasive method with tail cuff was performed in rats to record the systolic blood pres-sure during establishing the model of CIH induced hy-pertension.Mean arterial pressure (MAP)and heart rate (HR)were recorded in vivo on a PowerLab data acquisition system after CIH.Rats were fixed on the stereotaxic instrument to conduct microinjection in the PVN.We used Western blot to measure Ang Ⅱ level and AngⅡtype 1 receptor (AT1 R)protein expression in PVN.Results The level of PVN Ang Ⅱin CIH rats was significantly higher than that in Sham rats,a-long with increased AT1 R protein expression.Microin-jection of Ang Ⅱ(0.03,0.3,3 nmol)in bilateral PVN dose-dependently increased MAP in both CIH and Sham rats,and this response was significantly augmen-ted in CIH rats.Losartan (50 nmol),AT1 R antago-nist,had no effect on MAP in Sham rats,but caused significant MAP decreases in CIH rats,and prevented Ang Ⅱ-induced increases in MAP in both CIH and Sham rats.Conclusion The results suggest that the increased AngⅡrelease and enhanced AT1 R activation in the PVN contribute to CIH induced-hypertension in rats.

Objective To investigate the expression and significance of CDK4 and cyclin D1 in gastric carcinoma,and to discuss their correlation with WHO histological classification,TNM stages and lymph node metastasis.Methods Forty paraffin wax specimens from patients with gastric carcinoma were collected and expression of CDK4 and cyclin D1 proteins were detected by immunohistochemistry.Results Immunohistochemistry demonstrated that the positive rates for CDK4 and cyclin D1 protein were 65% and 55%,respectively.There was positive correlation between CDK4 and cyclin D1 proteins(P0.05).Conclusion CDK4 and cyclin D1 proteins are frequently overexpressed in gastric carcinoma and there is a positive relationship between the two proteins,which may be involved in the development of gastric carcinoma.
