Objective To discuss application of evidence-based nursing in nasopharyngeal carcinoma patients undergoing radiotherapy. Methods Evidence-based nursing was used in 33 nasopharyngeal carcinoma patients undergoing radiotherapy. Results After evidence-based nursing, all the patients actively cooperated with the doctors and nurses, lived through the treatment process smoothly, and radiotherapy complications were reduced or avoided. Conclusions Evidence-based nursing is an idealized nursing method which could reduce or avoid the complications and alleviate the pain of patients and improve the quality of nursing.

Stem cells and progenitor cells are the cells of origin for multi-cellular organisms and organs. They play key roles during development and their dysregulation gives rise to human diseases such as cancer. The recent development of induced pluripotent stem cell (iPSC) technology which converts somatic cells to stem-like cells holds great promise for regenerative medicine. Nevertheless, the understanding of proliferation, differentiation, and self-renewal of stem cells and organ-specific progenitor cells is far from clear. Recently, the Hippo pathway was demonstrated to play important roles in these processes. The Hippo pathway is a newly established signaling pathway with critical functions in limiting organ size and suppressing tumorigenesis. This pathway was first found to inhibit cell proliferation and promote apoptosis, therefore regulating cell number and organ size in both Drosophila and mammals. However, in several organs, disturbance of the pathway leads to specific expansion of the progenitor cell compartment and manipulation of the pathway in embryonic stem cells strongly affects their self-renewal and differentiation. In this review, we summarize current observations on roles of the Hippo pathway in different types of stem cells and discuss how these findings changed our view on the Hippo pathway in organ development and tumorigenesis.

ObjectiveToll-like receptors (TLRs) play important role in the progression and tumor immunity of some types of cancer,some research have demonstrated that agonist of TLR3 can trigger apoptosis of cancers.This study was proposed to investigate if Poly(I:C),the specific agonist of TLR3,could impact proliferation or apoptosis of progressive breast cancer cells MDA-MB-231,and to investigate the primary mechanism of the function.MethodsExpression of TLR1-10 mRNA was detected by quantitative real-time reverse transcription-polymerase chain reaction.Cell Counting Kit-8 was used to determine the inhibitory effect of Poly(I:C) on proliferation of MDA-MB-231 cells.Cell apoptosis was assayed by flow cytometry with V-FITC/PI staining.Results First,the toll-like receptors 1-10 were all expressed on MDA-MB-231 cells,while the expression level of TLR8 was lower than that of others.Second,according to the CCK-8,the proliferation of MDA-MB-231 cells was inhibited,but the apoptosis was not affected on the basis of Apoptosis Kit.At last,the mRNA expression of TNF-α、IFN-β and IFN-γ were elevated approximately 20 times after Poly(I:C) stimulation for 6 hours.ConclusionMDA-MB-231 cells express all toll-like receptors on mRNA level,and TLR8 was expressed lower than others.The stimulation of TLR3 with Poly(I:C) can inhibit the proliferation of MDA-MB-231,but had no effect on apoptosis.TNF-α、IFN-β and IFN-γ maybe participate in this process.

From the time of Neijing (Internal Classic) and Nanjing (Classic of Medical Problems) till the end of Qing dynasty, the medical scholars of each dynasty had taken the recognition of deqi as the subject in the stud- ies. Through the historical analysis, the content of regulating deqi was further understood in relevant ancient liter- ature. By checking the ancient works of acupuncture in each dynasty till the end of Qing dynasty, in reference to the evidences in over 10 works, such as Zhenjiu Dacheng (Great Compendium of Acupuncture and Moxibustion) , Zhenjing Zhinan (Instruction of Acupuncture Canon), Zhenjiu Daquan, and in association with the academic views of acupuncture masters in modern time, it was discovered that the medical scholars after the time of Neijing and Nanjing had enriched the understandings of deqi, such as the connection of cold and heat reaction, radiation to the affected site, reinforcing and reducing purpose in qi regulation. The methods of deqi regulations had, been explored till the end of Qing dynasty since the time of Neijing and Nanjing and the understandings of it were vari- ous among scholars.

Acupuncture-moxibustion theory believes that needling sensation is a crucial factor in influencing acupuncture efficacy. Judgment of occurrence of needling qi (qualitative measurement) and the intensity of needling qi (quantitative measurement) is the key section in studying the relationship between needling qi and efficacy. According to the relevant literatures, the judgment of the occurrence of needling qi mostly depended on the needling sensations, while a small amount of researches mentioned self-determined threshold or range of needling qi; the quantity of needling qi was measured by factor analysis, Massachusetts General Hospital Acupuncture Sensation Scale (MASS) based on exponential smoothing method, weighted average, addition of needling sensation score, etc. This article holds that the needling qi should be divided into two parts: overall needling qi and needling sensation components, the former referring to the occurrence and intensity of needling qi, and the latter for judging the different sensations and intensity. Currently, the studies on needling qi and efficacy should begin with single treatment at single point and multiple treatments at multiple points, to generally estimate the quality and quantity of needling qi, for seeking a qualitative and quantitative measurement in accordance with both acupuncture-moxibustion theory and clinical practice.

ObjectiveTo explore the relation between the uterine position and acupoint effect by analyzing the data of a clinical trial of electroacupuncture in treating primary dysmenorrhea.MethodThe uterine position was detected by ultrasonic examination;Visual Analogue Scale (VAS) was used to evaluate the pain degree before and after intervention; Retrospective Symptom Scale (RSS) was adopted to determine the improvement of symptoms.ResultThere were no significant differences in comparing the VAS score, real-time effect and post-treatment effect, and effective rate among different uterine positions (P>0.05). Electroacupuncture at Sanyinjiao (SP 6) can produce a real-time effect in releasing abdominal pain and relevant symptoms of dysmenorrhea in patients with anteversion of uterus, a less significant effect was shown in patients with retroposition of uterus, while no effect was shown in patients with uterus at middle position.ConclusionElectroacupuncture at Sanyinjiao possibly has a specific effect in releasing abdominal pain and relevant symptoms of dysmenorrhea at anteversion of uterus, and the uterine position may be related to the corresponding meridians and Zang-fu organs. The current statistical result indicates that there is no relation between the uterine position and the effect of Sanyinjiao, but this conclusion still needs proving by prospective randomized controlled clinicaltrials.

Qi arrival is the meridian qi response to acupuncture stimulation. Through analyzing the relevant concepts of qi arrival and summarizing the general understanding of it in clinic and on the basis of the collection of the relevant literature at home and abroad on the determination of qi arrival and its strength, the characteristics are analyzed on the present method and the method for the determination of qi arrival and its strength is discussed in terms of the results in the needling sensation scale. It is believed that the needling sensation and its strength can be used to determine whether the qi is arrived or not and its strength. The components of different types of needling sensation are much better applicable for the analysis on the characteristics and rules on the influence on qi arrival. This method is in compliance not only with the theoretic connotation of qi arrival, but also with the clinical general understanding, which lays the foundation for the analysis on the scale results.

Objective To explore the feasibility of using short-latency somatosensory evoked potentials (SLSEP) to quantitate Deqi.Methods A randomized crossover controlled trial was carried out. Healthy subjects were enrolled and allocated to treatment (thick needle, deep insertion and manipulation for Deqi) and control (thin needle, shallow insertion and no manipulation without Deqi) groups. Somatosensory evoked potentials were recorded before, during and after acupuncture. Deqi was assessed using the score scale in the subjets. The effects of Deqi and no Deqi at point Sanyinjiao (SP 6) on the potentials were observed.Results The preliminary exploration of the feasibility by the trial test showed that the effect of Deqi on short-latency somatosensory evoked potentials had certain regularity. It was worthy to be observed.Conclusion The plan is feasible. The formal test can be conducted.

Objective To assess the CT characteristics of thoracoabdominal localized Castleman disease (LCD) in 55 cases and correlate with histopathologic features. Methods Fifty-five patients with LCD proved histopathologically in thorax ( n = 25 ) and abdomen ( n = 30 ) were collected during past 20 years. The unenhanced and contrast-enhanced CT were performed in all patients. Two radiologists reviewed CT images and the CT findings were analyzed simultaneously. Results In 54 patients with hyaline-vascular type ( n = 50 ) and mixed type ( n = 4 ) localized CD, the lesion typically presented as solitary mass (90. 7% , 49 cases), with irregular or lobular or infiltrative margin ( 83.3% , 45 cases),central calcification (38. 9%, 21 cases), marked enhancement (100% , 54 cases), focal non-necrosis low attenuation areas (72. 2%, 39 cases), lymphadenopathy (70.4%, 38 cases) and dilated feeding vessels adjacent to the mass (96.3%, 52 cases). One lesion with plasma cell type localized CD presented as a mass with irregular margin, mild enhancement and central necrosis. Four morphologic patterns wereclassified on CT, including solitary mass with well-circumscribed margin (n =4), irregular or lobular margin ( n = 30), infiltrative or halo-like margin ( n = 16 ), and multiple coalescent maasses ( n = 5 ). Conclusion CT features of thoracoabdominal localized CD are closely related to the location and pathological type. LCD with hyaline-vascular and mixed type has typical CT characteristics, while LCD with plasma cell type has no typical CT findings.

Objective To investigate the expression and prognostic significance of serum protease C1 inhib-itor(SERPING1)and plasminogen activator inhibitor type 1(SERPINE1)in patients with sepsis.Methods A total of 132 patients with sepsis treated in the hospital from March 2018 to March 2020 were se-lected as the sepsis group.According to whether they died within 28 days of admission,they were divided into a death group(n=34)and a survival group(n=98).Enzyme linked immunosorbent assay was used to detect the expression of serum SERPING1 and SERPINE1.Multivariate Logistic regression model and receiver oper-ating characteristic curve were used to study the value of serum SERPING1 and serpine1 in evaluating the prognosis of patients'death.Results[Compared with the control group,serum SERPING1(331.12±51.80 ng/L vs.639.04±91.12 ng/L)was lower and serum serpine1(412.67±64.84 ng/L vs.42.33±10.32 ng/L)was higher in the sepsis group,and the differences were statistically significant(P＜0.05).[Compared to the survival group,the levels of serum SERPINE1,procalcitonin,C-reactive protein,Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score and Sequential Organ Failure Assessment(SOFA)score in the death group were higher,while serum SERPING1 was lower,and the differences were statistically significant(all P＜0.05).Serum SERPING1 showed negative correlation with APACHE Ⅱ and SOFA scores(r=-0.779,-0.653,P＜0.05),while serum SERPINE1 showed positive correlation with APACHE Ⅱ and SO-FA scores(r=0.740,0.685,P＜0.05).APACHE Ⅱ score,SOFA score,and serum SERPINE1 were risk fac-tors affecting the prognosis of sepsis patients,while serum SERPING1 was a protective factor.The area under the curve of serum SERPING1 and SERPINE1 combined for the evaluation of the death in sepsis patients was 0.938(95％CI:0.893-0.968),which was significantly higher than 0.860(95％CI:0.812-0.899)and 0.838(95％CI:0.781-0.868)of the single detection,and the differences were statistically significant(Z=3.861,4.015,P＜0.001).Conclusion The elevated levels of serum SERPING1 and SERPINE1 in patients with sepsis are related to the severity of the patient's condition.The combination of the two has high prognos-tic value for sepsis patients.
