Objective To investigate the clinical nursing path on the psychological status of cerebral infarction patients hospitalized for the first time.Methods Two hundred cerebral infarction patients hospitalized for the first time were equally randomized into the observation group and control group:the former used conventional nursing method and the latter a clinical nursing path.The self-rating depression scale(SDS)and self-rating anxiety scale(SAS)were used to assess their psychological state.Results After intervention,the scores on SDS and SAS in the former group were significantly lower than those in the latter group(all P<0.05). The satisfaction rate in the former was higher than that of the control(P<0.05).Conclusion The clinical nursing path makes it possible to effectively alleviate the psychological burden of the cerebral infarction patients hospitalized for the first time and improve the patients’satisfaction with nursing working.

Objective To explore the roles of macrophage inflammatory protein-1?(MIP-1?)in hypoxic-ischemic encephalopathy(HIE)of newborn infarnts.Methods Serum samples were obtained in 24,72 h and 7 d after birth respectively from 34 newborn infants with HIE,and 20 newborn infants without HIE as control group.Enzyme-linked immunosorbent assay(ELISA)method was used to determine the serum concentrations of MIP-1?.Results Levels of MIP-1? in newborn infants with HIE [(12.47?2.51)ng/L]were significantly higher than that of newborn infants without HIE [(8.63?2.63)ng/L](P0.05).Conclusions MIP-1? are involved in HIE of neonates,and the more severe damage,the higher levels in serum,which suggests that,as an inflammatory mediator,the MIP-1? may play an important role in involvement of brain hypoxic-ischemic damage.

Background It is well known that the diminution of visual acuity appears before notable complications in some high myopic eyes.However,whether the impaired vision is associated with the change of retinal thickness at macula area is still under investigation.Objective This study was to investigate the relationship of macular retinal thickness with the change of visual acuity in high myopic eyes.Methods A consecutive caseobservational study was performed.Two hundred and forty-five eyes of 132 patients with the diopter of-6.00～-20.00 D were enrolled in this study during the January 2011 to January 2012 in Beijing Tongren Eye Center.All of the patients received the measurement of retinal thickness with Fourier Domain Optical Coherence Tomography (FDOCT),and the scan mode was MM6.The eyes were divided into the corrected vision ≥0.9 group and the corrected vision ≤0.8 group.In addition,the eyes were assigned to the non-posterior staphyloma group,posterior staphyloma Ⅰ group (macular symmetry) and posterior staphyloma Ⅱ group (macular gradient).The retinal thicknesses in different quadrants at the macular zone were measured and calculated by OCT software.Results The demography was matched in different groups.Corrected visual acuity was significantly increased in the corrected vision ≥ 0.9 group than that in the corrected vision ≤0.8 group (1.02±0.16 vs.0.62±0.08) (t=3.233,P=0.001).Retinal thickness value at fovea was (256.28±13.19) μm in the corrected vision ≥0.9 group,and that in the corrected vision ≤0.8 group was (231.17 ± 10.96) μm,with a significant difference between the two groups (t =2.134,P =0.031).The corrected visual acuity was 1.00±0.27,0.78±0.21 and 0.90±0.13 in the non-posterior staphyloma group,posterior staphyloma Ⅰ group and posterior staphyloma Ⅱ group,respectively,showing significant difference among the three groups (F=15.760,P=0.015),and the corrected visual acuity of the non-posterior staphyloma group and posterior staphyloma Ⅱ group were significantly higher than that of posterior staphyloma Ⅰ group (q =16.131,P =0.006 ; q =-10.831,P=0.008).A significant difference also was seen in the mean retinal thickness among the three groups (F=2.316,P =0.025).The mean retinal thickness in the posterior staphyloma Ⅰ group was (234.21 ± 15.69) μm,which was significantly smaller than (252.25± 15.31) μm of the posterior staphyloma Ⅱ group (q =12.977,P =0.023).There were no significant difference in the retinal thickness at para-fovea area among the three groups (F=0.318,P =0.078).However,significant difference was found at peri-fovea area in different groups (F=1.925,P =0.013).The mean retinal thicknesses at peri-fovea area was (273.26 ± 16.37) μm in the posterior staphyloma Ⅱ group and was significantly smaller than (289.11 ± 19.30) μm of the posterior staphyloma Ⅰ group and (290.33 ± 17.12) μm of the non-posterior staphyloma group (q =-8.305,P =0.023 ; q =-7.011,P =0.012).Conclusions The retinal thickness at fovea is associated with the corrected visual acuity in high myopic eyes.The thinning of retinal thickness at the vertex of posterior staphyloma is one of causes of visual function impairment.

Objective: To evaluate the long-term prognosis of coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI) by risk stratification with American College of Cardiology (ACC)/American Heart Association (AHA) classification of coronary lesions. Methods: Data used in this study derived from the I-LOVE-IT 2 trial. I-LOVE-IT 2 trial was a prospective, multicenter, randomized, assessor-blinded, noninferiority study. A total of 1 255 patients in I-LOVE-IT 2 trial with only one lesion and underwent biodegradable polymer drug-eluting stent implantation were included and grouped according to ACC/AHA classification of coronary lesions, namely type A/B1 lesion group (n=184), type B2 lesion group (n=457) and type C lesion group (n=614). The primary endpoint was 48-month patient-oriented composite endpoint (PoCE), a composite of all-cause mortality, all myocardial infarction, stroke, and/or any revascularization. The secondary endpoints were target lesion failure (TLF), components of PoCE, major bleeding (bleeding academic research consortium(BARC) type 3-5) and definite/probable stent thrombosis within 48 months. The incidences of endpoint events were compared in the three groups. The multivariable Cox hazard ratio model was used to analyze the independent predictors of PoCE and TLF at 48 months. Results: Incidences of PoCE at 48 months were significantly higher in patients with type C lesion compared with patients with type A/B1 (24.43%(150/614) vs. 14.13%(26/184), P<0.05) or B2 lesion (24.43%(150/614) vs. 15.97%(73/457), P<0.05). The multivariable Cox hazard ratio model showed that the type C lesion were the independent predictors of 48-month PoCE (HR=1.59, 95%CI 1.21-2.08, P<0.001) and TLF (HR=2.31, 95%CI 1.53-3.49, P<0.001). After multivariable adjustment, the HRs of PoCE for patients with type C lesion versus type A/B1 and type B2 were 1.91 (95%CI 1.25-2.92, P=0.003) and 1.64 (95%CI 1.23-2.20, P<0.001), respectively. Meanwhile, the HRs of TLF for patients with type C lesion versus type A/B1 and type B2 were 2.45 (95%CI 1.29-4.64, P=0.006) and 2.55 (95%CI 1.62-4.02, P=0.001), respectively. Conclusions: The ACC/AHA classification of coronary lesions has good discrimination with long-term outcomes for CAD patients undergoing PCI. The type C lesion is associated with a worse prognosis, enough attention should be paid in these patients during routine clinical management.

Small intestinal obstruction is a common complication of primary gastrointestinal cancer or metastatic cancers.Patients with this condition are often poor candidates for surgical bypasses,and placement of self-expanding metal stent (SEMS) can be technically challenging.In this study,we examined the feasibility of combined application of single-balloon enteroscope (SBE) and colonoscope for SEMS placement in patients with malignant small intestinal obstruction.Thirty-four patients were enrolled in this study,among which 22 patients received SEMS placement by using SBE and colonoscope,while the other 12 patients received conservative medical treatment.The patients were followed up for one year.Stent placernent was technically feasible in 95.5％ (21/22).Clinical improvement was achieved in 86.4％ (19/22).For the 19 clinical success cases,the average time of benefits from a gastric outlet obstruction scoring system (GOOSS) increase ≥1 was 111.9±89.5 days.For the 12 patients receiving conservative medical treatment,no significant improvement in GOOSS score was observed.Moreover,a significant increase of Short-Form-36 health survey score was observed in the 19 patients at time of 30 days after stent placement.By Kaplan-Meier analysis,a significant survival improvement was observed in patients with successful SEMS placement,compared with patients receiving conservative medical treatment.Taken together,combined use of SBE and colonoscope makes endoscopic stent placement feasible in patients with malignant small intestinal obstruction,and patients can benefit from it in terms of prolonged survival and improved quality of life.

OBJECTIVETo study the inhibitory effect of flavonoids from Glycyrrhiza uralensis on thioacetamide-induced chonic hepatic fibrosis in rats and the effect on the protein expressions of transforming growth factor-β1 (TGF-β1) and Caspase-3 in livers.

METHODMale Sprague-Dawley rats were randomly divided into totally seven groups: the normal control group, the model group, LF groups s (400, 200, 100, 50 mg · kg(-1) · d(-1)) and the silymarin positive control group (30 mg · kg(-1) · d(-1)). The hepatic fibrosis model was induced in the rats through intraperitoneal injection with 3% thioacetamide (TAA) at a dose of 150 mg · kg(-1) body weight twice a week for 12 weeks. During the course, the control group and the model group were orally administered with saline (1 mL · kg(-1) · d(-1)). After the modeling and drug intervention, the pathologic changes and fibrosis in liver tissues were observed by HE staining and Masson's Trichrome staining. The serum alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and liver hydroxyproline (HYP) contents were assayed by biochemical process. The serum hyaluronic acid (HA) was assessed by radioimmunoassay. In addition, the protein expressions of liver TGF-β1 and Caspase-3 were examined by immunohistochemical method. The mRNA expression of TGF-β1 in hepatic tissues was examined by quantitative Real-time PCR analysis.

RESULTCompared with the model group, flavonoids can protect the integrity of the structure of liver tissues, significantly reduce the hepatic cell degeneration and necrosis and the proliferation of fibrous tissues, notably reduce the serum AST, ALT, ALP and HA and HYP in hepatic tissues and down-regulate the protein expressions of liver TGF-β1 and Caspase-3 and the mRNA expression of TGF-β1 in hepatic tissues.

CONCLUSIONThe licorice flavonoids can resist the thioacetamide-induced hepatic fibrosis in rats. Its mechanism may be related to the down-regulation of the protein expressions of TGF-β1 and Caspase-3.

Objective To test the reliability and validity of Chinese version of Illness Cognition Questionnaire(ICQ)in women with breast cancer. Methods From October,2016 to May,2017,297 women with breast cancer were investigated with the Chinese version of the ICQ and Brief Illness Perception Questionnaire(B-IPQ).The reliability and validity of the Chinese version of ICQ were tested. Results The Cronbach's α of three subscales of ICQ(helplessness,acceptance and perceive benefits)were 0.855,0.857, 0.878,and the test-retest reliability of three subscales were 0.946,0.963,0.901(P<0.001).A confirmatory factor analysis was tested,χ2/df=2.500,SRMR=0.063,CFI=0.920.The factor load capacity of each subscales was 0.37 to 0.84 and the correlation of helplessness,acceptance and perceive benefits was-0.49 to 0.81(P<0.001).The correlation coefficient of criterion-related validity of the helplessness subscale of ICP with B-IPQ was 0.727(P<0.001). Conclusion The Chinese version of ICQ has good reliability and validity,which is a valuable research tool in clinical studies of psychological cognition of patients with breast cancer.

AIM To fit the moisture adsorption models for Astragali Radix aqueous extract.METHODS For the aqueous extract prepared by decocting,the moisture adsorption kinetics curve and adsorption/desorption isotherms were drawn by gravimetry,and then the data on moisture adsorption were fitted.The fitted models were optimized according to evaluation indices of root mean square error (RMSE),residual sum of squares (RSS) and coefficient of determination (R2).RESULTS The double exponential model for moisture adsorption kinetics curve and Peleg model for adsorption/desorption isotherms were considered as the two best models with regard to their fitting effects (R2 values were the closest to 1,RMSE and RSS values were the closest to 0).Among them,various adsorption/desorption isotherms all belonged to type Ⅱ ("S" isotherm),while the higher equilibrium moisture content of desorption isotherm than that of adsorption isotherm contributed to obvious type H3 hysteresis phenomenon.CONCLUSION Double exponential model and Peleg model can well fit the moisture adsorption kinetics curve and adsorption/desorption isotherms of Astragali Radix aqueous extract,respectively.

Lung cancer is the leading cause of cancer-related deaths worldwide. Acquired drug resistance and metastasis are the main causes of treatment failure in lung cancer. Tumor microenvironment is a complex network for the survival and progression of tumor cells, in which inflammatory factors play a critical role in drug resistance and metastasis. Interleukin (IL)-8 is one of critical pro-inflammatory cytokines responsible for cell proliferation, invasion and metastasis, drug resistance and early recurrence in lung cancer. A serum based approach is advantageous for providing a real-time detection and evaluation of disease status in patients. In this review, we summarize the recent advances of IL-8 in predicting prognosis and radiation-induced lung toxicity (RILT), as well as increasing resistance and stem-like characteristics of lung cancer.
