认知干预联合奥施康定控制癌痛的临床疗效研究

目的　分析认知干预联合奥施康定控制癌痛的临床疗效。方法　将我科收治的80 例采用奥施康定治疗的癌痛患者随机分成观察组和对照组，各40 例，对照组采用常规癌痛护理管理方法，观察组患者在常规癌痛管理的基础上配合认知干预。评估和比较两组患者的癌痛控制效果、使用奥施康定的顾虑、服用奥施康定的依从性和生活质量评分的改善情况。结果　观察组患者的癌痛控制效果、使用奥施康定没有顾虑的患者百分比、遵医嘱按时按量服药的人数百分比及生活质量评分均显著优于对照组患者，差异有统计学意义（P<0.05）。结论　认知干预能使癌痛患者对使用奥施康定的顾虑降低，提高患者的依从性，增强药物对癌痛的控制效果，并明显改善患者的生活质量。     

Inhibition of focal adhesion kinase enhances antitumor response of radiation therapy in pancreatic cancer through CD8+ T cells

Objective:Pancreatic ductal adenocarcinoma(PDAC)is a deadly malignancy,due in large part to its resistance to conventional therapies,including radiotherapy(RT).Despite RT exerting a modest antitumor response,it has also been shown to promote an immunosuppressive tumor microenvironment.Previous studies demonstrated that focal adhesion kinase inhibitors(FAKi)in clinical development inhibit the infiltration of suppressive myeloid cells and T regulatory(T regs)cells,and subsequently enhance effector T cell infiltration.FAK inhibitors in clinical development have not been investigated in combination with RT in preclinical murine models or clinical studies.Thus,we investigated the impact of FAK inhibition on RT,its potential as an RT sensitizer and immunomodulator in a murine model of PDAC.Methods:We used a syngeneic orthotopic murine model to study the effect of FAKi on hypofractionated RT.Results:In this study we showed that IN10018,a small molecular FAKi,enhanced antitumor response to RT.Antitumor activity of the combination of FAKi and RT is T cell dependent.FAKi in combination with RT enhanced CD8+T cell infiltration significantly in comparison to the radiation or FAKi treatment alone(P<0.05).FAKi in combination with radiation inhibited the infiltration of granulocytes but enhanced the infiltration of macrophages and T regs in comparison with the radiation or FAKi treatment alone(P<0.01).Conclusions:These results support the clinical development of FAKi as a radiosensitizer for PDAC and combining FAKi with RT to prime the tumor microenvironment of PDAC for immunotherapy.     

Significant impact of cryopreserved amniotic membrane on acute ocular Stevens-Johnson syndrome and toxic epidermal necrolysis

The ocular surface is covered by an epithelium encompassing an area including the cornea,the limbus and the conjunctiva bordered by the upper and lower lids.The healthy state of the ocular surface epithelium depends on a stable and protective preocular tear film when the eye is open.A stable preocular tear film is governed by sound ocular surface defense that involves effective neuroanatomic integration of compositional and hydrodynamic factors by two neural reflexes (1).     

血清TP、TS、DPD 表达与SOX 方案治疗晚期胃癌疗效的相关性

目的　探讨血清TS、TP 及DPD 表达与替吉奥化疗治疗晚期胃癌患者疗效的相关性。方法　选择符合要求的晚期胃癌患者化疗前血清标本，使用酶联免疫吸附试验（ELISA）检测患者外周血中TP、TS、DPD 的表达水平，分析其与患者化疗疗效的相关性。结果　晚期胃癌患者血清中TS 低表达者化疗有效率高于高表达者（77.78% vs. 28.57%，P<0.05），TP 高表达者化疗有效率高于低表达者（66.67% vs. 25%，P<0.05），DPD 低表达者化疗有效率高于高表达者（62.5% vs. 21.43%，P<0.05）。结论　晚期胃癌患者血清TS、TP、DPD 表达水平与SOX 方案化疗的临床疗效有关，TS、DPD 阴性及TP 阳性的晚期胃癌患者SOX 方案化疗的疗效更好。     

Reduced anoctamin 7(ANO7) expression is a strong and independent predictor of poor prognosis in prostate cancer

Objective:Anoctamin 7(ANO7)is a calcium2+-dependent chloride ion channel protein.Its expression is restricted to prostate epithelial cells.The exact function is unknown.This study aimed to analyze ANO7 expression and its clinical significance in prostate cancer(PCa).Methods:ANO7 expression was assessed by immunohistochemistry in 17,747 clinical PCa specimens.Results:ANO7 was strongly expressed in normal prostate glandular cells but often less abundant in cancer cells.ANO7 staining was interpretable in 13,594 cancer tissues and considered strong in 34.4%,moderate in 48.7%,weak in 9.3%,and negative in 7.6%.Reduced staining was tightly linked to adverse tumor features[high classical and quantitative Gleason grade,lymph node metastasis,advanced tumor stage,high Ki67 labeling index,positive surgical margin,and early biochemical recurrence(P<0.0001 each)].The univariate Cox hazard ratio for prostate-specific antigen(PSA)recurrence after prostatectomy in patients with negative vs.strong ANO7 expression was 2.98(95%confidence interval 2.61–3.38).The prognostic impact was independent of established pre-or postoperatively available parameters(P<0.0001).Analysis of annotated molecular data showed that low ANO7 expression was linked to TMPRSS2:ERG fusions(P<0.0001),elevated androgen receptor expression(P<0.0001),as well as presence of 9 of 11 chromosomal deletions(P<0.05 each).A particularly strong association of low ANO7 expression with phosphatase and tensin homolog(PTEN)deletion may indicate a functional relationship with the PTEN/AKT pathway.Conclusions:These data identify reduced ANO7 protein expression as a strong and independent predictor of poor prognosis in PCa.ANO7 measurement,either alone or in combination,might provide clinically useful prognostic information in PCa.
