Background and purpose: The morbidity of colorectal cancer in China increased year by year. This study aimed to explore the signiifcance of ADAMTS9 protein levels and promoter methylation in colorectal cancer onset and progression. Methods:ADAMTS9 promoter methylation status was detected by methylation speciifc PCR method in 162 colorectal cancer patients’ peripheral blood DNA samples; Plasmatic ADAMTS9 protein levels was detected by enzyme-linked immunosorbent assay method in 162 colorectal cancer patients and 150 healthy subjects. Results: Compared with healthy people, patients with colorectal cancer had a significant lower ADAMTS9 protein level in plasma [(65.25±9.70)μg vs (50.28±9.66)μg, P<0.001];ADAMTS9 gene promoter methylation was observed in 66 among 162 colorectal cancer patients (40.7%);The plasma level of ADAMTS9 protein in patients with methylated ADAMTS9 gene had signiifcantly reduced (P<0.001), while the plasma level of ADAMTS9 protein in patients with low ADAMTS9 protein had signiifcantly increased (P=0.007);ADAMTS9 methylation is closely related to tumor size (larger, P=0.017) and tumor differentiation degree (P=0.029), ADAMTS9 protein low expression is closely related to invasion depth (P=0.020), lymph node metastasis (P=0.019) and Dukes staging (P=0.002).Conclusion: ADAMTS9 protein downregulation induced by DNA promoter methylation may be involved in the pathogenesis, invasion and metastasis, and promote the progression in colorectal cancer.

Objective To investigate the relationship between programmed death receptor ligand 1 (PD-L1) and regulatory T cell(Treg) in non-small cell lung cancer.Methods Seventy-nine patients with non-small cell lung cancer who were treated in Hainan Provincial People's Hospital from December 2013 to December 2015 were selected.The levels of PD-L1 and Treg in cancer tissues and adjacent tissues were detected,observed the relationship with clinical pathological features,and analyzed the correlation of PD-L1 level and Treg infiltration.Results High expression of PD-L1 (53.2％,42/79) and Treg (50.6％,40/79) in cancer tissues were significantly higher than those in adjacent tissues (3.8％ (3/79),5.1％ (4/79)),the difference was significant (x2 =9.761,9.002,P＜0.05).High expression of PD-L1 (87.5％,28/32) and Treg(84.4％,27/32)were significantly higher in stage]Ⅲ and Ⅳ cancer tissues than those in stage Ⅰ and Ⅱ cancer tissues(29.8％(14/47),27.7％ (13/47)),the difference was significant (x2 =8.958,7.274,P ＜ 0.05).High expression of PD-L1 (85.3％,29/34) and Treg (88.2％,30/34) were significantly higher in lymph node metastasis cancer tissues than those in non-lymph node metastasis cancer tissues (28.9％ (13/45),22.2％ (10/45)),the difference was significant(x2=8.146,9.056,P＜0.05).The high level of PD-L1 in cancer tissues was positively correlated with high Treg infiltration (r =0.762,P＜0.05).Conclusion The expression of PD-L1 and Treg in non-small cell lung cancer tissues is related to the lymph node metastasis and stage,and the high expression of PD-L1 is positively correlated with the high infiltration of Treg.

Objective:To study the feasibility of electronic gingivoplasty on the subjects suffering from high blood sugar or blood coagulating dysfunction on rat model.Methods:Electronic gingivoplasty was performed in 10 SD rats with high blood sugar and 10 with blood coagulating dysfunction on the right side of mandible and scalpel gingivoplasty on the left.For each group of diseased rats 10 healthy rats were used as the controls. Gingival tissue slices of the rats with high blood sugar and the controls were obtained 1,24, 72 hours, one and two weeks after operation respectively, and processed for histological observation. The bleeding condition were evaluated with paper tips during the operations on the rats with blood coagulating dysfunction and the controls.Results:The process of histological reaction in the tissues of operation area after electronic gingivoplasty was basically similar to that after scalpel gingivoplasty. Electronic surgery caused more slight inflammatary reaction than scalpel surgery in high blood sugar group. The amount of bleeding during electronic surgery was significantly smaller than that during scalpel surgery in blood coagulating dysfunction group.Conclusion:Electronic surgery is feasible for gingivoplasty on the subjects with high blood sugar or blood coagulating dysfunction.

Objective To explore the clinical features of sentinel polyps (rectal polyps with proximal colon carcinoma), and the correlation between sentinel polyps and proximal colon carcinoma. Methods The clinical data of 331 patients with rectal polyps were retrospectively analyzed. According to the combination condition of proximal colon carcinoma, the patients were divided into sentinel polyps group (observation group, 37 cases) and pure rectal polyps group (control group, 294 cases). The family history, laboratory examination, colonoscopy, clinical pathological features, treatment, sequelae and short-term prognosis were compared between 2 groups. Results The family history rate, positive rate of tumor marker and the incidences of polyps maximum diameter>1 cm, polyps>5 pieces, adenomatous polyp in observation group were significantly higher than those in control group:35.1%(13/37) vs. 4.8%(14/294), 67.6%(25/37) vs. 6.8%(20/294), 62.2%(23/37) vs. 46.6%(137/294), 43.2%(16/37) vs. 11.9%(35/294) and 83.8%(31/37) vs. 35.4%(104/294), and there were statistical differences (P<0.01). The patients in control group did not have special find in colonoscopy. The majority patients in observation group had new organisms around the lumen growth in colonoscopy, but the intestinal canal between rectal polyps and proximal colon carcinoma did not have special find. The majority pathologic type of proximal colon carcinoma patients in observation group was papillary adenoearcinoma and tubular adenocarcinoma, 75.7%(28/37). Duke stage:A stage was in 11 cases (29.7%, 11/37), B stage in 11 cases (29.7%, 11/37), C stage in 9 cases (24.3%, 9/37), and D stage in 6 cases (16.2%, 6/37). In control group, 282 patients (95.9%, 282/294) were treated by endoscope, and they were cured and discharged. In observation group, 15 patients (40.5%, 15/37) were treated with radical operation, 9 patients (24.3%, 9/37) by endoscope, 7 patients (18.9%, 7/37) with palliative surgery, 4 patients (10.8%, 4/37) with chemotherapy, and 2 patients (5.4%, 2/37) with symptomatic treatment;the patients were followed up for 6-12 months, the 23 patients with complete tumor resection did not relapse, 12 patients showed tumor reduction or symptomatic relief, and the other 2 patients died. Conclusions If maximum diameter over 1 cm, multiple and adenomatous polyps exist, the possibility of carcinogenesis of the polyps or the proximal colon should be awared. The patients should be followed up in short-term and complete the whole colon examination.

Objective To evaluate the effects of psychological nursing process on the quality of life and its related factors in maintenance hemodialysis patients.Methods Ninety maintenance hemodialysis patients from September 2013 to September 2014 were selected as research object,and they were divided into control group 45 cases and observation group 45 cases by random digits table method.The patients in control group received routine psychological intervention,while the patients in observation group received psychological intervention with nursing process.The two groups were evaluated and compared with Short Form 36 Health Survey Questionnaire score (SF-36), Self-Efficacy for Managing Chronic Disease(SEMCD) and Perceived Social Support Scale(PSSS) before and after the intervention at 6th and 12th month.The score changes of each scale were analyzed by repeated-measures analysis of variance and multivariate analysis of variance.Results The number of patients that had completed the whole intervention process was 42 in control group and 44 in observation group.The SF-36 scores of two groups were all increased gradually with the extension of intervention time (time effect, all P＜0.01), but compared with control group, observation group had a trend towards better SF-36 score except for the dimension of physical functioning(interactive effect, all P＜0.01).In all dimensions of SF-36, the scores of physical role,general health,vitality and social function in observation group as a whole were higher than those in control group (group effect, all P＜0.05).Similarly, the SEMCD and PSSS scores of two groups were all increased gradually with the extension of intervention time (time effect, all P＜0.01), but the increasing trend of observation group was more obvious than control group (interactive effect, all P＜0.01).Conclusions The application of psychological nursing process can effectively improve the life quality of maintenance hemodialysis patients, and have a satisfied long-term effect,which may be related to the continuous improvement of psychological nursing process on the self-efficacy and perceived social support of the patients.

Objective To study the effects ofShenqi YizhiGranules (SQYZ) on learning and memory and content of Aβ1-42 of cerebral tissue in 5XFAD mice with Alzheimer’s disease; To discuss its mechanism on improving learning and memory ability of 5XFAD mice.Methods Four-month-old C57BL?6 wild type mice were randomly divided into NS control group and SQYZ control group, and the 5XFAD mice were randomly divided into model group, SQYZ group and huperzine-A (HupA) group, 15 mice in each group. Each group were given same volume for gavage for 60 d. After treatment, the learning and memory ability were evaluated by nesting test, passive avoidance and Morris water maze test. The senile plaques and content of Aβ1-42, ionized calcium binding adapter molecule 1 and glial fibrillary acidic protein in cerebral cortex and hippocampus were detected by immunohistochemical staining and immunofluorescence, respectively.Results Compared with NS control group, the score of nesting test in model group significantly decreased; the step-through latency in passive avoidance was shortened and the escape latentcy in Morris water maze test was prolonged; the quantity of senile plaques and content of Aβ1-42 increased in cerebral cortex and hippocampus; the activation of glial cells significantly increased. In the SQYZ group, the above-mentioned indexes reached or approached the level of wild type control mice. The difference between SQYZ group and model group was statistically significant (P<0.05,P<0.01).Conclusion SQYZ improved learning and memory ability in 5XFAD mice, which may be related to reduction of senile plaques, inhibition of over activation in glial cells and reduction of content of Aβ1-42 in cerebral cortex and hippocampus.
