ABSTRACT
In this study, 15 second-year resident doctors who had standardized training of OBGYN were taken as research subjects to discuss the effect of training resident doctors with obstetrics forceps by using simulation teaching method. The simulation teaching process includes theoretical study, theoretical examination, simulation teaching of forceps skills and Assessment of forceps skills. In theoretical study section: before learning to use forceps, the students acquired the theoretical knowledge by flipped teaching micro-video mode. In theoretical examination section: the mastery of basic clinical knowledge of using forceps was evaluated through online assessment. In simulation teaching of forceps skills: students who scored 8/10 points were admitted to enter the simulation teaching process, and they had practical training of scenario simulation skills in Clinical Skills Center. In assessment of forceps skills: the mastery of forceps skills was evaluated by standardized forceps delivery procedure items. The results showed that the students in the simulation teaching group had excellent teaching assessment results, and the resident doctors had more confidence in operating forceps independently, and the teaching effect was ideal, which could further promote the simulation teaching of obstetric clinical skills.
ABSTRACT
OBJECTIVE@#To investigate the expression pattern of adapter protein with a Src-homology 2 domain (SH2B1), the suppressor of cytokine signaling-3 (SOCS3), protein-tyrosine phosphatase 1B (PTP1B) and neturopetide Y (NPY) in obese and normal mice hypothalamus and its relation with serum leptin and insulin levels.@*METHODS@#The obesity animal model was prepared with healthy C57/bl6 mice. Lee's index and Homeostasis model assessment-insulin resistance (HOMA-IR) were calculated. The mRNA levels of SH2B1, SOCS3, PTP1B and NPY were measured by fluorescent quantitation RT-PCR. The SH2B1 and NPY protein expressions were detected by Western blot.@*RESULTS@#Compared with the normal mice of the same age, SH2B1 mRNA expression in the obese mice hypothalamus decreased. SOCS3 and PTP1B mRNA expression increased. Western blot showed that SH2B1 protein expression decreased, while NPY protein expression increased in the obese mice. Linear correlation analysis showed that the serum leptin and fasting insulin levels were negatively correlated with SH2B1mRNA expression and positively correlated with SOCS3 and PTP1B mRNA expression.@*CONCLUSION@#SH2B1, SOCS3, PTP1B and NPY are key factors for obesity development.

BACKGROUND:Many researchers appealed that coronary atherosclerotic heart disease patients were medical treated while special psychological intervention should be integrated into the rehabilitation plans (biology-psychology-social treatment) for coronary atherosclerotic heart disease patients.Pertinence psychological intervention would be processed after finding out mental health state of coronary atherosclerotic heart disease patients.OBJECTIVE:To make principal component analysis for mental health state of coronary atherosclerotic heart disease patients with relapsing pain in chest after percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) by questionnaire investigation,and to find out the primary factors.METHODS:A total of 40 coronary atherosclerotic heart disease patients with relapsing pain in chest after PCI and CABG were selected,(25 males and 15 females),mean age of (60±10) years old.It was used that the mental health section of the integrative system for diagnosing and assessing health state in Chinese population,including body symptoms,positive emotion,negative emotion,cognitive ability,behavior trouble,self-evaluation and social adapting problem.RESULTS AND CONCLUSION:Totally 4 principle component factors which the accumulative contribution rate reached to 83.89% were extracted.The first principle component factors which the contribution rate reached to 40% mainly demonstrated behavior trouble and social adapting problem.The second one mainly demonstrated positive emotion and negative emotion,the third for cognitive ability and self-evaluation,and the fourth for body symptoms.The behavior trouble and social adapting problem of coronary atheroscleroticheart disease patients with relapsing pain in chest after PCI and CABG must be paid great attention,and positive emotion would be leaded,negative emotion would be lowered.
ABSTRACT
Objective To investigate the distribution characteristics of protein tyrosine phosphatase 1B (PTP1B) gene IVS6+G82A and Pro303Pro polymorphisms in Chinese children and determine the effect of PTP1B gene IVS6+G82A and Pro303Pro polymorphisms on the pathogenesis of childhood obesity. Methods A total of 147 Chinese obese and 118 healthy children were randomly selected and enrolled to identify IVS6+G82A and Pro303Pro genotypes by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay. Waist circumference (WC), waist to hip ratio (WHR), percentage of body fat (%BF),systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (FPG), serum triglycerides (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), plasma fasting insulin (FINS), homeostasis model assessment for insulin resistance (HOMA-IR), and plasma leptin were examined. Results The allele frequencies of IVS6+G82A and Pro303Pro were 59.5% and 19.4% in obese children, and 53.4% and 11.0% in healthy children, respectively. There were significant differences in allele frequencies of Pro303Pro polymorphism between the obese and the control group. Pro303Pro polymorphism was associated with body mass index, WC, TG, and LDL C in the obese subjects. There was not di fference in the genotype distributions or allele frequencies of IVS6+G82A polymorphism between the obese and the control group. Further analysis showed no association between the genotypes of IVS6+G82A and clinical characteristics in the obese subjects. The linkage disequilibrium analysis for IVS6+G82A and Pro303Pro (D′: 0.441, r2: 0.027) was weak.Conclusion PTP1B gene Pro303Pro polymorphism might be associated with the pathogenesis of obesity in children and could affect the lipid metabolism in Chinese obese children.
