Objective To investigate the clinical characteristics between elderly and non-elderly patients with ulcerative colitis (UC) in order to provide the base for diagnosis and management of the disease.Methods Two hundred and four patients with UC admitted to Shengjing Hospital from January 2009 to December 2011 were enrolled in this study.The patients were divided into elderly group (≥60 years of age) and non-elderly group(＜ 60 years of age).The clinical manifestation,laboratory examination indices and endoscopic feature were recorded and analyzed.Results Among the 204 cases with UC,33 (16.2％,33/204) were elderly patients,and 171 (83.8％,171/204) were non-elderly patients.Onset peak of U C was ranged from 30-39 years old.There was no significant difference in terms of other indices of clinical presentations,extraintestinal manifestations,complications,clinical and endoscopic score between two groups.The rate of abdominal distension,constipation,difficult defecation,alteration of intestinal flora,hypokalemia and hypoproteinemia in elderly group were 36.4％,9.1％,6.1％,66.7％,45.5％,36.4％ respectively,higher than that in in nonelderly group (14.6％,1.2％,0.6％,48.0％,14.0％,20.5％ respectively),and there was significant differences between groups (x2 =8.808,7.260,5.724,3.876,17.660 and 3.942 respectively,P ＜ 0.05).Endoscopic examination revealed that the colonic lesion parts in elderly patients was limited in left-side colon and protosigmoid,which was different from that of no-elderly group (P =0.044).Conclusion The elderly patients showed a similar clinical manifestation with non-elderly patients.However,the colonic lesion parts in elder group was limited to left-side colon and protosigmoid.They also had the higher rate of hypoproteinemia,hypokalemia and alteration of intestinal flora,which needed to pay more attention.

Objective To evaluate the significance of the expression of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) as prognostic indicators for patients with stage Ⅱ colorectal cancer. Methods A total of 285 patients with stage Ⅱcolorectal cancer who underwent potentially curative surgery were enrolled in the study. A high CEA level was defined as a level exceeding 5 ng/ml and a high CA19-9 level was defined as a level exceeding 37 U/ml. Patients were followed up every 3 months to review CEA and CA19-9 levels. Two years later, the chest and abdominal CT examination were performed every 3 months, and then every 6 months until 5 years. Results Out of these 285 patients, 99 (42.60%) patients had high CEA levels, 25 (8.77 %) patients had high CA19-9 levels, and 12 (4.21 %) patients had both high CEA and CA19-9 levels. The overall survival rates of patients with both high CEA and CA19-9 levels were significantly worse than those of others (P< 0.05). During the study, 51 recurrences were diagnosed. There were 22 hepatic recurrences, 10 pulmonary recurrences, 9 local recurrences, 8 lymph node recurrences, and 2 peritoneal recurrences. CT, CEA and CA19-9 were the first abnormal examinations in 30, 5 and 8 recurrent patients, respectively. In 27 % of recurrent patients, the recurrence was detected earlier by CEA and CA19-9 than that by CT. Conclusions The detection of preoperative CEA and CA19-9 levels is useful for predicting the prognosis after potentially curative surgery in patents with stage Ⅱ colorectal cancer. For early detection of occult recurrence of colorectal cancer, tumor markers are relevant.

This paper proposed a rehabilitation training system with electromyography (sEMG) feedback for stroke patients based on ARM embedded system and LabVIEW. The system can achieve real-time acquisition, processing and dualview of multi-channel sEMGs and compute related sEMG parameters including iEMG, RMS, MPF and co-contraction ratio. The system was detected by clinical experiments and related inspection department. The result showed that the system is functional, interactive and in accordance with the relevant standards for medical devices so that it can fully satisfy the clinical demands. In addition, the system can help doctors to master the training state of the patient more effectively in a real-time and quantitative way that is direct to improve the training programs of stroke patients.

Objective To confirm the correlation between pre or post processing semen parameters and clinical pregnancy rate in infertile couples with male factors undergoing intrauterine insemination (IUI) .Methods The pregnancy rate based on ovulation in‐ducing agent in infertile couples with male factors infertility per the 2010 world health organization criteria treated with IUI was e‐valuated .One hundred and twenty eight cycles were divided into pregnant group (16 cycles) and non‐pregnant group(112 cycles) . The pre or post processing semen parameters were retrospectively evaluated .Results The overall pregnancy rate was 12 .5% .All parameters in this study has no statistically significant difference between the two groups (P>0 .05) .Logistic multivariate analysis showed that there was no significant correlation between semen parameters and clinical pregnancy rate (P> 0 .05) .Conclusion There are no significant correlations between semen parameters and clinical pregnancy rate when the normal forms of patients with male infertility was 4% or higher .No semen parameters could predict results of clinical pregnancy .

Objective To investigate the effect of sperm preparation in male infertility on sperm morphology and DNA fragmentation index(DFI). Methods Four hundred men were divided into the groups of fertile , teratozoospermics and unexplained subfertility. Sperm morphology and DFI were analyzed before and after the sperm preparation. Results Sperm abnormal morphology and DFI in the infertility group were higher than those in the fertile group ,but significantly decreased after sperm preparation. The method of density gradient separation results in obtaining better sperm(P<0.01). Conclusions Compared to the method of swimming up ,the method of density gradient separation could result in obtaining sperm with improved normal morphology and DNA integrity.

Objective:To investigate the current situation of paternal self-efficacy of support breastfeeding of late prematurity and analyze the factors affectingpaternal self-efficacy of support breastfeeding.Methods:This study was a cross-sectional survey. From July to October 2021, the fathers of 210 late prematurity in Neonatology and NICU wards of Shanxi Children′s Hospital, were selected by convenience sampling method for the research object. The survey was carried out using the General Information Questionnaire, Iowa Infant Feeding Attitude Scale and Father Support Breastfeeding Self-Efficacy Scale-Short Form, multiple linear regression was used to analyze the influencing factors of paternal self-efficacy of support breastfeeding of late prematurity.Results:The total score of Father Support Breastfeeding Self-Efficacy Scale-Short Form was 46.22 ± 10.03, and the total score of Iowa Infant Feeding Attitude Scale was 59.31 ± 5.65, which were positively correlated ( r = 0.224, P<0.01). In the multiple linear regression analysis, whether or not to receive breastfeeding education, feeding methods, family opinions, and fathers′ attitudes towards breastfeeding were the main factors affecting fathers′ self-efficacy in supporting breastfeeding ( t values were - 3.07 to 2.35, all P<0.05). Conclusions:The paternal support breastfeeding of late prematurity level was at a lower level. It is suggested that medical staff should not only pay attention to puerpera and baby, but also pay attentionto father and family, and construct personalized health education based on co-parenting theory.

Fathers play an important role in supporting maternal breastfeeding. Father's self-efficacy in supporting breastfeeding can predict the outcome of breastfeeding. This article reviews the concept, evaluation tools, roles, status, influencing factors, and intervention measures of self-efficacy in father's support for breastfeeding, so as to provide suggestions for further promoting the formation of breastfeeding intervention plans, thereby improving marital relationships, and promoting infant health.
