Objective To observe the effects of MSH2 gene re expression on estrogen-induced apoptosis of colon cancer cells LOVO,and to explore its mechanisms.Methods According to different plasmid and whether with estradiol intervention,colon cancer LOVO cells were divided into empty plasmid with ethanol group,empty plasmid with estradiol group,MSH2 with ethanol group,MSH2 with estradiol group,estrogen receptor (ER) β with ethanol group,ERβ with estradiol group,ERβ with MSH2 and ethanol group and ERβ with MSH2 and estradiol group,and received corresponding treatment.The expression of MSH2,ERβ protein and apoptosis related caspase 3 protein were detected by Western blotting.Cell viability was measured by cell counting kit-8.Cell DNA fragments of each group were isolated with apoptosis DNA fragments isolation kit.And the DNA ladder was observed.The rate of apoptosis was detected by flow cytometer.Single factor variance analysis was performed for comparison among multiple groups,and t test was used for comparison between the two groups.Results After transfection,the expression of the MSH2 and ERβ at protein level in LOVO cells significantly increased and neither of their expression was effected by estradiol.The expression levels of caspase 3 cleavaged active fragments of ERβ with estradiol group and ERβ with MSH2 and ethanol group were higher than other groups,and there was no significant difference between these two groups.The LOVO cell viability of empty plasmid with ethanol group,empty plasmid with estradiol group,MSH2 with ethanol group,MSH2 with estradiol group,ERβ with ethanol group,ERβ with estradiol group,ERβ with MSH2 and ethanol group and ERβ with MSH2 and estradiol group was 1.72 ±0.25,1.74 ± 0.31,1.77 ± 0.35,1.74±0.33,1.70±0.34,1.02±0.48,1.71±0.31 and 1.07±0.18,respectively,and the differences between the groups were statistically significant (F=3.791,P＜0.05).Among them,the LOVO cell viability of ERβ with estradiol group was lower than that of ERβ with ethanol group,accordingly,that of ERβ with MSH2 and estradiol group was lower than that of ERβ with MSH2 and ethanol group,that of ERβ with estradiol group was lower than that of empty plasmid with estradiol group,that of ERβ with MSH2 and estradiol group was lower than that of MSH2 with estradiol group,and the differences were statistically significant (t=3.158,3.075,3.648,3.253,all P＜0.05).DNA ladder formed from DNA fragments of apoptosis cells was seen in ERβ with estradiol group and ERβ with MSH2 and estradiol group.The apoptosis rate of empty plasmid with ethanol group,empty plasmid with estradiol group,MSH2 with ethanol group,MSH2 with estradiol group,ERβ with ethanol group,ERβ with estradiol group,ERβ with MSH2 and ethanol group and ERβ with MSH2 and estradiol group was 7.86±0.19,7.87±0.39,8.39±1.02,9.05±1.54,7.54±0.99,19.77±2.35,7.76±1.32 and 19.30±1.75,respectively,and the differences between groups were statistically significant (F=45.436,P＜0.05).Among them,the apoptosis rate of ERβ with ethanol group was lower than that of ERβ with estradiol group,that of ERβ with MSH2 and ethanol group was lower than that of ERβ with MSH2 and estradiol group,that of empty plasmid with estradiol group was lower than that of ERβ with estradiol group,that of ERβ with MSH2 and estradiol group was lower than that of MSH2 with estradiol group,and the differences were statistically significant (t =8.260,9.133,8.596,7.617,all P＜ 0.05).Conclusions Estrogen may promote colon cancer cell apoptosis through ERβ pathway.The process of apoptosis maybe related with caspase protein,MSH2 may not be involved in the regulation of this signal pathway.

Objective To analyze and compare the differences in application of 24-hour dietary recall and dietary balance index (DBI) in dietary survey and evaluation of patients with type 2 diabetes mellitus,meanwhile investigate their nutrition status.Method This was a cross-sectional study.A total of 100 type 2 diabetes inpatients at the age of 19-59 were recruited from Shanghai Jiaotong University Affiliated Sixth People's Hospital from December 2013 to February 2014.They were surveyed and evaluated by 24-hour dietary recall and DBI respectively.Result The micronutrient intake in patients with type 2 diabetes was not sufficient.Compared with RNI,the intake of vitamin B1,B2,and calcium was less than 50％.The average of DBI lower bound score (DBI-LBS) of the 100 patients was 32.1±6.1,65％; the patients were in moderate or severe deficit of food intake.DBI higher bound score (DBI-HBS) was 4.4±2.8.No significant excess intake problem was found.Dietary quality distance was 36.4±6.9.Eighty-seven percent of them had a dietary patterns of mode B.Conclusion Dietary patterns in type 2 diabetes patients were not reasonable.Nutrition education and nutrition intervention for type 2 diabetes should be emphasized.The two methods can be used to evaluate dietary quality independently,but it would be better to evaluate the quality of the patients' diet using two dietary survey methods together.

Objective:To develop a nursing performance management indicator system for a dental specialty hospital based on the balanced scorecard framework.Methods:Utilizing the balanced scorecard as a theoretical framework, the preliminary indicator system was developed through literature analysis and semi-structured interviews. From July to September 2023, two rounds of expert panel inquiries were conducted to select, modify, and refine the indicators, thus establishing the system. The engagement of the experts was indicated by the effective response rate of the questionnaires, the authority of the experts by an expert authority coefficient, and the consensus among expert opinions by Kendall's coefficient of concordance.Results:In the first round, 22 questionnaires were distributed, and 22 were effectively returned, yielding an 100% response rate. In the second round, 22 questionnaires were distributed, and 19 were effectively returned, with an 86% response rate. The authority coefficients for the two rounds were 0.866 and 0.868, respectively, while Kendall's coefficients of concordance were 0.333 and 0.335 ( P<0.01). The final system comprised four primary indicators, 13 secondary indicators, and 38 tertiary indicators. Conclusions:The nursing performance management indicator system for the dental specialty hospital developed in this study is scientifically sound, comprehensive, and reliable. It can be a reference for nursing performance management in dental specialty hospitals.

Objective To compare the efficacy and safety of humidified high-flow nasal cannula (HHFNC)and nasal continuous positive airway pressure (nCPAP) for moderate and severe bronchiolitis treatment in infants.Methods Thirty-two infants who were diagnosed as moderate and severe bronchiolitis admitted to Department of Pediatric Critical Care Medicine,the Affiliated Hospital of Qingdao University from September 2016 to May 2017 were selected,and they were randomly assigned into HHFNC group(17 cases) and nCPAP group(15 cases).The heart rate,breathing,oxygen saturation (SpO2),arterial partial pressure of oxygen [Pa (O2)],partial pressure of carbon dioxide [Pa (CO2)],pH value after treatment for 12 h,the duration of non-invasive ventilation and the incidence rates of invasive ventilation use,complications were compared between the 2 groups.Results After the treatment for 12 h,in HHFNC group,the heart rate was (130.88 ± 2.87) times/min,respiratory rate was (37.35 ± 3.55) times/min,SpO2 was(97.06 ± 1.43)％,pa(O2) was (99.65-±8.07) mmHg,pa(CO2) was (35.88 ±4.27) mmHg,pH was 7.42 ± 0.03;while in the nCPAP group,the heart rate was (135.73 ± 6.29) times/min,respiratory rate was (41.40 ± 4.40)times/min,SpO2 was (96.00 ± 1.13) ％,Pa (O2) was (91.33 ± 9.45) mmHg,pa (CO2) was (40.13 ± 3.72)mmHg,pH was 7.39 ± 0.03.The breathing,heart rate,oxygen saturation and arterial blood gas in both groups after treatment were improved significantly compared with those before treament,and the differences were statistically significant (all P ＜ 0.05);after treatment for 12 h,the heart rate,breathing,oxygen saturation and arterial blood gas of HHFNC group were improved more than those of the nCPAP group,and the differences had statistical significance (all P ＜ 0.05).The duration of non-invasive ventilation was (45.88-± 6.49) hours in HHFNC group,and (49.33 ± 8.99) hours in nCPAP group,so there was no difference between the 2 groups (t =1.254,P =0.219).There was 12 cases (80.0％) of mild complication in nCPAP group and 5 cases(29.4％) in HHFNC group,while the incidence rate of invasive ventilation use was 3 cases(20.0％) in nCPAP group and 1 case (5.9％) in HHFNC group.Conclusion The efficacy and security of HHFNC on moderate and severe bronchiolitis are better than those of nCPAP,and it is recommended for clinical application widely.
