[Abstract ] CHD1L is a newly identified oncogene located at Chr 1q21,its oncogenic role in tumorigenesis is through unleashed cell proliferation, G1/S transition, inhibition of apoptosis and Chromatin instability .It is an independent biomarker that can affect tumour′s process, prognosis and survival rate.The underlying mechanisms of CHD1L activation may disrupt the cell death program via binding the apoptotic protein Nur77 or exterting relevant function by mediate CHD 1L′s target genes (ARHGEF9, TCTP, SPOCK1, and NTKL) .This paper mainly introduces its oncogenic role and research progress of related molecular mechanism .

Objective To explore the treatment effect and failure patterns associated with different clinical target volume on patients with esophageal carcinoma treated with 5-filed intensity modulated radiotherapy (IMRT), and to determine whether involved field irradiation (IFI) is practicable in these patients. Methods A total of 88 patients with esophageal carcinoma between January 2012 to June 2014 underwent IMRT in our hospital, were divided into IFI group and elective nodal irradiation(ENI) group according to the CTV range for a concurrent control study. Results One-year and two-year survival rate in IFI group and ENI group were 75.0%, 45.5% and 70.5%, 43.2% respectively (P > 0.05). Local failure rate in IFI and ENI groups was 27.3% and 22.7% respectively, distant metastasis failure rates 22.7% and 18.2% respectively and regional failure rate outside the radiation field 11.4% and 4.5%, which showed no statistical difference (P > 0.05). Subgroup analysis indicated failure outside the radiation field tended to increase for primary lesion located in the up thoracic or clinical stageⅠ in IFI group. The volume dose histogram of lung V5, V20, V30 and mean lung dose of ENI group were greater than that of IFI group, while V5 of lung and the mean lung dose had statistical difference. Conclusions The survival rate and local control rate have no significant differencein IFI group and ENI group, so IFI is feasible for some esophageal carcinoma, but it should be cautious to choose IFI for those primary lesion located in the up thoracic or clinical stageⅠ.

Objective:To retrospectively analyze the treatment effect and the patterns of failure associated with different clinical target volume on patients with esophageal cancer treated with three dimensional conformal or intensity modulated radiotherapy, and to determine whether involved field radiotherapy is practicable in these patients. Methods:A total of 68 patients with esophageal squa-mous cell carcinoma between January 2007 to June 2011 in our hospital underwent three dimensional conformal or intensity modulated radiotherapy, according to the CTV range is divided into lymph involved-field group (involved field group) and lymph extended field group (extended field group). Results:In Involved field group and expand field group the survival rate of 1, 2 years were 59%, 41%and 61%, 39% respectively (P=0.56), and local control rates were 66%, 48% and 68%, 49% respectively(P=0.78). The total failure rates of involved field and the expand field were 63%and 66%(P=0.89). The local failure rate was 53%and 59%, distant metastasis failure rates were 47%and 44%, the regional failure rates were 11.8%and 7.5%in Involved field and the expand field, there were no difference in Statistics (P=0.39). The lung V10, V20, V30 and mean lung dose of extended field group were greater than that of the in-volved field group, while the mean lung dose and V10 has statistical difference. Conclusion:The involved field group was similar as the extended field group in the survival rate and local control rate, the regional recurrence and distant metastasis are the main cause of treatment failure, so the involved field radiotherapy is feasible for locally advanced esophageal carcinoma.

ObjectiveTo investigate the application value of selfmade modified hepatic pedicle occluding band in laparoscopic special section hepatectomy.MethodsForty-ifve patients who underwent laparoscopic special section hepatectomy in the Second Afifliated Hospital of Nanchang University between July 2014 and July 2015 were enrolled in this prospective study. The informed consents of all patients were obtained and the local ethical committee approval was received. Among the patients, 17 were males and 28 were females with the age ranging from 28 to 71 years old and the median of 50 years old. Five cases underwent resection of segmentⅣb, 8 of segmentⅤ, 10 of segmentⅦ, 9 of segmentⅧ, 8 of segmentⅥ+Ⅶ, and 5 of segmentⅤ+Ⅶ. According to the random number table method, the patients were divided into the group of hepatic inlfow occlusion with the selfmade modiifed hepatic pedicle occluding band (the modiifed group,n=18) and the traditional surgery group (the traditional group,n=27). Hepatic inlfow was not occluded or was occluded by Pringle maneuver in the traditional group. The length of operation, intraoperative blood loss and postoperative length of stay in two groups were compared usingt test.ResultsThe patients in both groups completed the surgery successfully. No conversion to laparotomy was observed in the modiifed group, while the rate of conversion to laparotomy in the traditional group was 22%(6/27). The length of operation, intraoperative blood loss and postoperative length of stay in the modiifed group were respectively (226±95) min, (421±90) ml and (10±4) d, while those in the traditional group were respectively (286±95) min, (501±91) ml and (14±4) d, and signiifcant differences were observed (t=-2.104,-2.899,-2.913;P<0.05).Conclusions The application of selfmade modified hepatic pedicle occluding band in laparoscopic special section hepatectomy is safe and feasible. And it can conveniently and effectively control the hepatic inlfow.

Objective To construct an evaluation index system of"Internet+Traditional Chinese Medicine nursing"service capability,in order to provide references for the standardized and effective evaluation of"Internet+Traditional Chinese Medicine nursing"service capability.Methods Literature analysis and semi-structured interview method were adopted,and three-dimensional quality structure model was used as the theoretical framework to initially construct the"Internet+Traditional Chinese Medicine nursing"service capability evaluation index item pool.From July to 0ctober 2022,the Delphi method was used to conduct 2 rounds of consultation with 16 experts from Guangdong Province,to evaluate the enthusiasm,authority,degree of opinion concentration and degree of opinion coordination of the experts in the correspondence consultation,and the weight of the index system was determined with the combination of chromatography analysis.Results 2 rounds of expert letter consultation were conducted.The questionnaire recovery rates were 100％,and the authority coefficients were 0.844 and 0.834,respectively.Kendall coordination coefficients were 0.161 and 0.110,respectively(P＜0.001).The first level indexes of the index system are structure evaluation,process evaluation and outcome evaluation.There were 3 first-level evaluation indicators,14 second-level evaluation indicators and 57 third-level evaluation indicators.Conclusion The evaluation index is scientific and practical,and it is carried out around the Internet+Traditional Chinese Medicine nursing capability,which provides a certain reference for the effective evaluation of the service capability of"Internet+Traditional Chinese Medicine nursing".
