Purpose: Molecular residual disease (MRD) is a promising biomarker in colorectal cancer (CRC) for prognosis and guiding treatment, while the whole-exome sequencing (WES) based tumor-informed assay is standard for evaluating MRD based on circulating tumor DNA (ctDNA). In this study, we assessed the feasibility of a fixed-panel for evaluating MRD in CRC. Materials and Methods: Seventy-five patients with resectable stage I-III CRC were enrolled. Tumor tissues obtained by surgery, and preoperative and postoperative day 7 blood samples were collected. The ctDNA was evaluated using the tumor-agnostic and tumor-informed fixed assays, as well as the WES-based and panel-based personalized assays in randomly selected patients. Results: The tumor-informed fixed assay had a higher preoperative positive rate than the tumor-agnostic assay (73.3% vs. 57.3%). The preoperative ctDNA status failed to predict disease-free survival (DFS) in either of the fixed assays, while the tumor-informed fixed assay-determined postoperative ctDNA positivity was significantly associated with worse DFS (hazard ratio [HR], 20.74; 95% confidence interval [CI], 7.19 to 59.83; p < 0.001), which was an independent predictor by multivariable analysis (HR, 28.57; 95% CI, 7.10 to 114.9; p < 0.001). Sub-cohort analysis indicated the WES-based personalized assay had the highest preoperative positive rate (95.1%). The two personalized assays and the tumor-informed fixed assay demonstrated same results in postoperative landmark (HR, 26.34; 95% CI, 6.01 to 115.57; p < 0.001), outperforming the tumor-agnostic fixed panel (HR, 3.04; 95% CI, 0.94 to 9.89; p=0.052). Conclusion Our study confirmed the prognostic value of the ctDNA positivity at postoperative day 7 by the tumor-informed fixed panel. The tumor-informed fixed panel may be a cost-effective method to evaluate MRD, which warrants further studies in future.

Objective To investigate the relationship between the treatment of EGFR-TKI icotinib and the prognosis of advanced lung adenocarcinoma patients with EGFR mutation. Methods Patients with advanced lung adenocarcinoma who had EGFR19 and 21 gene mutations and were treated with EGFR-TKI icotinib were enrolled. The relationships of clinical features, EGFR gene mutation subtypes, and different sites with patients'prognosis were analyzed. Results A total of 101 patients with advanced lung adenocarcinoma were included in this study, including 58 cases (57.4%) of EGFR gene exon 19 deletion mutation (EGFR Del19) and 43 cases (42.6%) of EGFR gene exon 21 point mutation (EGFR L858R). The objective response rate was 63.4%. The mPFS and mOS were 13 months and 27 months, respectively. In addition, the mPFS and mOS of EGFR Del19 and EGFR19 mutation 746-750 were higher than those of EGFR L858R and other EGFR mutations, respectively. Meanwhile, multivariate analysis showed that the number of metastatic sites and pleural metastasis were independent influencing factors of patients'OS (P=0.027; P=0.041). The mOS of patients with the number of metastatic sites ≤3 and without pleural metastasis were 29 and 27 months, respectively. Conclusion There is no significant difference found in overall survival of advanced lung adenocarcinoma patients treated with icotinib among different EGFR mutation subtypes and sites. Herein, the overall survival time is longer in patients with less than three metastatic sites and without pleural metastasis.

At present, the medical mode has changed from bio-psycho-social medical model to "4 P" medical mode. Therefore, it is necessary to fully consider the individual needs of patients, treat patients equally, adheres to the principle of faith and compliance, and adhere to the humanistic nursing concept. To prevent nurse-patient disputes, we should start from three aspects. Firstly, we should reform the current model of nurse education and training, reform the content of education and attach importance to moral sentiment education. Secondly, we should strengthen the cooperation between doctors and nurses, improve the level of health education, and build a harmonious nursing environment and a social atmosphere of respecting medical staff. Finally, we call for strengthening medical legislation and protecting the legitimate rights and interests of nurses with legal weapons.

Objective To explore the influence of clinical indicators in patients with thrombocytopenia syndrome (SFTS) with severe fever on disease development and prognosis.Methods The SFTS patients who were admitted to the Department of Infection Diseases of Wuhan Union Hospital between April 1, 2015 and October 30, 2015 were included.Among 164 patients with SFTS, there were 136 cases recovered and 28 cases died.Clinical date including clinical manifestations and laboratory test index were collected and retrospectively analyzed.The correlation between the prognosis and clinical indicators were analyzed with the Spearman correlation analysis, the discriminatory power of clinical dates were tested with the area under the receiver-operating characteristic curve.Results The average age of died patients in the study was (64.5±9.1), which increased significantly(t=-3.609,P<0.01) compared with recovered patients with (56.9±10.2).Laboratory results suggest all patients had a drop in white blood cell and platelet count;almost all patients had a drop in serum calcium levels, and a rise in aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creatine kinase (CK), activated partial thromboplastin time (APTT), D-dimmer levels.The nucleic acid quantification of SFTSV suggests death patients (5.83±0.98) lg TCID50/mL was significantly higher than the recovered patients (3.96±1.08) lg TCID50/mL, with statistical difference (t=-8.49, P<0.01).Conclusions Age, the nucleic acid quantification of SFTSV, CK and APTT are factors can be used to predict prognosis of SFTS.

Objective To observe the relationship between injury of corticospinal cord tract (CST) in basal ganglia and upper limb func-tion after stroke using diffusion tensor imaging (DTI). Methods 18 stroke inpatients hospitalized from January, 2013 to July, 2015 accepted DTI, and their upper limb function was evaluated with simple Fugl-Meyer Assessment and Japan Upper Limb Function Test. The fractional anisotropy (FA) of CST in basal ganglia of affected and unaffected sides were compared, and the correlation between FA of affected CST and upper limb motor function were analyzed. Results The FA was significantly less in the affected CST than in the unaffected CST (t=-21.09, P<0.001). The FA of the affected CST correlated with the scores of simple Fugl-Meyer Assessment (r=0.570, P<0.05) and Japan Upper Limb Function Test (r=0.509, P<0.05). Conclusion CST is injured after stroke, which may related to the upper limbs motor function impairment.

OBJECTIVE To investigate risk factors and nursing protective measures controlling hospital infection in patients after neck dissection. METHODS The data of 116 patients after neck dissection from Aug 2000 to Aug 2005 were collected, and the hospital infection condition was analyzed in comparison with non-infection group. RESULTS Hospital infection rate was 18.97% (22/116) and case-time rate was 21.55%(25/116). Of 25 occasions in hospital infections, 48% were infection of operative incision and 24% were infection of respiratory tract. The risk factors for hospital infection in patients with neck dissection might be associated with patient's duration of hospitalization, history of chronic disease , age and invasive operation. CONCLUSIONS There is a high hospital infection incidence rate in patients after neck dissection , it is necessary to monitor high risk patients.

OBJECTIVETo study the mechanism of anti-tumor activity of Acanthopanax gracilistylus extract (Age).

METHODSThe tumor cells proliferation was detected by using (3H)-TdR incorporation method, and the effects of Age on cell cycle of tumor cells, retinoblastoma (Rb) protein and cyclin-dependent kinases (Cdk) were analyzed by flow cytometry and Western blotting assay, respectively.

RESULTSIt was indicated by cytoactivity test in vitro that Age only had effect in inhibiting the proliferation of tumor cells, it couldn't lead to death of cells. Under action of Age, the proliferation of tumor cells was halted at G0/G1 stage of cell cycle, and showed no direct cytotoxic effect by Age. Age could induce lowering of the expression of Rb, Cdk2 and Cdk4, cause halt of tumor cell proliferation.

CONCLUSIONThe tumor inhibitory effect of Age is realized by way of regulating the activity of cell cycle controlling enzymes to suspend the proliferation of tumor cells.

Objective To compare the antitumor effects and chemical components of the extracts in cultivated Cordyceps sinensis (Cs) fungus HK-1 and natural Cs. Methods The cultivated Cs fungus HK-1 and natural Cs were extracted with petroleum ether (PE), ethyl acetate (EtOAc), ethanol (EtOH), and water. The cytotoxicity of all the extracts was observed with MTT assay on breast cancer cell line MCF-7, mouse melanoma cell line B16, human premyelocytic leukemia cell line HL-60, and human hepatocellular carcinoma cell line Hep G2. The antitumor activity in vivo of the extract was further studied with animal model. The chemical constituents in the extracts were analyzed by HPLC. Results All of the extracts from the cultivated Cs fungus HK-1 had much stronger cytotoxicity on B16 than those from natural Cs, and the EtOAc extract had the most potent activity. The activity of EtOAc extract from the cultivated Cs fungus HK-1 was more potent than that from natural Cs on all the four cancer cell lines. EtOAc extract from the cultivated Cs fungus HK-1 also can inhibit the growth of tumor in vivo. Chemical components of all extracts were analyzed and ergosterol and adenosine were found to be potential compounds. Conclusion The cultivated Cs fungus HK-1 has stronger antitumor activity than natural Cs and is a potential source of antitumor compounds.
