Objective: To study the expression of CD138 in normal cervical mucosal tissue,cervical intraepithelial neoplasia ( CINⅠ/Ⅱ and CINⅢ) and cervical squamous cell carcinoma.And to investigate the clinical pathologic significance of CD 138 expression with lymph node metastasis , microvascular density ( MVD ) , CD68 expression and clinical stage in cervical squamous cell carcinoma.Methods:To detected the expression of CD 138 in 120 cases of cervical squamous cell carcinoma ,106 cases of CINⅢ,14 cases of CINⅠ/Ⅱand 54 cases of normal cervical mucosa tissues.Results: The expression of CD138 was lowest in cervical cancer tissue,followed by normal cervical mucosal tissue ,CIN I/II and CINIII,that there had significant difference (P<0.001).The expression level of CD138 was higher in without lymph node metastasis group than in lymph node metastasis group ( P<0.05 ).In cervical cancer , the expression level of CD 138 was higher in early stage ( stage 0 andⅠ) than in advanced stage (Ⅱ) ( P<0.001 );and higher in CD68 expression negative group than in positive group (P<0.05).Furthermore,MVD was higher in CD138 expression negative group than in positive group ( P<0.05 ).Conclusion: CD138 play an important role in the process of development of cervical squamous cell carcinoma,especially for the role of lymph node metastasis is more obvious.CD138 could be used as a indicators for determinate the process of progress in cervical squamous cell carcinoma.

Objective:To explore the construction and implementation effect of clinical-thinking patterned curriculum for parallel graduate students with "running through clinical diagnosis and treatment process."Methods:In this study, 94 Batch 2016-2017 graduate students with clinical medical professional degree in Shanxi Provincial People's Hospital were selected as the research subjects. Among them, 48 Batch 2017 parallel graduate students were selected as the experimental group. The curriculum of clinical-thinking patterned training of "running through the clinical diagnosis and treatment process" was used. In addition to participating in the degree courses and residency courses, a series of training to improve the clinical-thinking ability were introduced. And 46 Batch 2016 parallel graduate students were divided in the control group, using a traditional curriculum and only participating in degree courses and residency courses. The differences among mini-clinical evaluation exercise (Mini-CEX) scores, direct observation of procedural skills (DOPS) scores, objective structured clinical examination (OSCE) scores and students' satisfaction were compared by t test, chi-square test and repeated measures analysis of variance. Results:The Mini-CEX scores showed the average scores of other aspects except humanistic care were higher than those of the control group, and the score of communication skills was significantly higher than that of the control group [(6.55±0.98) vs. (5.77 ±1.12)], with significant differences ( t=3.62, P<0.001). In the DOPS scores, except for the skills of communication with patients, ability to consider patient's feelings and practice of occupational literacy, the average scores of other aspects of the experimental group were higher than those of the control group, and the real operation-ability score of clinical skills was significantly higher than that of the control group [(6.38 ± 1.38) vs. (5.53±1.23)], with a significant difference ( t=3.12, P=0.002). In terms of the outpatient receiving station, the emergency treatment station, the clinical thinking station①, the clinical thinking station②, the specialist skill station, the auxiliary examination station and the case writing station, their OSCE scores at different stages in the experimental group were higher than those in the control group, and in terms of clinical thinking station①, the score of the experimental group was significantly higher than that of the control group, with a significant difference ( F=6.51, P=0.012). The satisfaction rate of the experimental group in terms of curriculum was higher than that in the control group except for the future career development, and in improving logical-thinking ability, the score of the experimental group was significantly higher than that of the control group, with a significant difference ( χ2=19.18, P<0.001). Conclusion:The curriculum of clinical-thinking ability with "running through the clinical diagnosis and treatment process" can enhance the clinical practical ability of parallel graduate students, making them meet the residential academic standards as soon as possible and effectively promoting the training quality of the students.

Objective To explore the value of layer-specific strain in assessment of left ventricular function in patients with heterozygous familial hypercholesterolemia (HeFH) with normal left ventricular ejection fraction (LVEF).Methods Thirty-four patients with diagnosed HeFH and underwent transthoracic echocardiography were included as HeFH group,while 29 healthy volunteers were taken as control group.EchoPAC software was used to obtain endocardial longitudinal strain (LSendo),myocardial longitudinal strain (LSmyo) and epicardial longitudinal strain (LSepi) of the epicardial,and then statistical analysis was performed.Results LSendo and LSmyo in HeFH group were significantly lower than those in control group (P＜0.001).LSendo and LSmyo were negatively correlated with total cholesterol and low density lipoprotein cholesterol (all P＜0.05).Conclusion Layer-specific strain of left ventricular is of great value in assessing early myocardial damage in patients with HeFH.

Objective: To understand smoking behavior and related factors among college and middle school students in Inner Mongolia Autonomous Region, so as to provide a technical basis for targeted tobacco control interventions. Methods: In September 2023, a total of 93 647 students in Inner Mongolia Autonomous Region were randomly selected by stratified cluster sampling from 12 league cities and 103 banner counties (cities districts) to conduct a questionnaire survey. The χ2 test and binary Logistic regression analyses were used to explore the current situation of adolescent smoking and its related factors. Results: The prevalence of college and middle school students who tried smoking was 10.2%, and the prevalence of current smokers was 4.4%. The binary Logistic regression model showed that students in high school, vocational high school, university, males, those from unstable family, boarders, individuals who sew someone smoking at home, at school, in public places, drinking alcohol, inhaling volatile solvents for pleasure, using cough suppressant except for coughing, using sedative without a doctors permission, being scolded by parents, experiencing school bullying, being addicted to the Internet, having depressive symptoms, anxiety symptoms, and low selfesteem were more likely to attempt smoking and currently smoke (attempt smoking:OR=1.38, 2.59, 1.75, 3.24, 1.18, 1.43, 1.25, 1.43, 1.43, 0.79, 9.18, 1.42, 1.17, 1.65, 1.52, 1.31, 1.58, 1.41, 1.11, 1.17； current smoking:OR=1.61, 4.76, 3.76, 4.45, 1.17, 1.44, 1.27, 1.58, 1.69, 0.68, 7.99, 1.64, 1.12, 2.31, 1.48, 1.37, 1.26, 1.31, 1.35, P<0.05). Teenagers with parents who had graduated from high school and eat breakfast every day had a relatively low risk of trying and current smoking (OR=0.78, 0.83, 0.79, 0.84, 0.78, 0.68, P<0.05). Conclusions Adolescent smoking behaviours in Inner Mongolia Autonomous Region exhibit obvious clustering pattern in the school setting. Associated factors includes demographic characteristics, secondhand smoke exposure, daily behaviours and substance abuse, and psychological behaviours. Schools, families and society should work together to create a smokefree environment to protect adolescents from the harms of tobacco.

OBJECTIVE：To eval uate therapeutic effic acy，safety and economical efficiency of Ginkgolide injection versus Butylphthalide injection in the treatment of ischemic stroke. METHODS ：Among the GISAA of Ginkgolide injection in the treatment of ischemic stroke of large-artery atherosclerosis ，106 patients who were given Ginkgolide injection+Asprin enteric-coated tablets but did not use butylphthalide in any dosage in previous trial group were selected as ginkgolide group ；56 patients who were given Butylphthalide injection+Ginkgolide injection+Asprin enteric-coated tablets in previous placebo group were selected as control group. The effects ，safety and economical efficiency were compared between 2 groups. Effect indexes included recurrence rate ， mortality，NIHSS score ，modified Rankin score （mRS），Barthel index and comprehensive efficacy. The safety indexes included incidence of bleeding event and adverse event during treatment. Cost-minimization analysis was used for economic evaluation. RESULTS：There was no statistical difference in recurrence rate ，mortality，NIHSS score ，the proportion of subjects with mRS 0-2，Barthel index ，comprehensive efficacy and the incidence of adverse event between 2 groups on 28th day after treatment （P＞ 0.05）. NIHSS score of ginkgolide group was better than that of control group on 7th and 14th day （P＜0.05）. Results of cost-minimization analysis showed that total cost of ginkgdide group was （13 768.19±4 981.54）yuan on 14th day of treatment ， which was significantly lower than （22 578.52±7 523.23）yuan of control group （P＜0.01）. The results of sensivity analysis indicated that the minimum lost analysis was stable. CONCLUSIONS ：For the treatment of ischemic stroke ，ginkgolide+aspirin is similar to butylphthalide+aspirin in improving clinical outcome and safety of 28 days，but is better than it in short-term efficacy of improving neurological deficit ， and better short-term economical efficiency.

Objective To explore the value of diffusion-tensor imaging(DTI)of different gray matter nuclei in the diagnosis and assessment of prodromal Parkinson's disease(pPD)under logistic regression model.Methods A total of 20 patients with pPD were collected as case group and 28 healthy people as control group(HC group).All patients were examined by MRI plain scan and DTI.DSI studio was used to post-process the DTI images of all patients.Parameters(FA,MD,AD,RD)of basal ganglia,midbrain and brainstem of patients with pPD and HC group were automatically extracted and statistically analyzed.Logistic regression analysis was used to draw the Receiver Operating Characteristic(ROC)curve to analyze and compare the diagnostic efficacy of individual diagnosis and combined diagnosis of each parameter.And the correlation between the parameters of each group and MMSE score was analyzed.Results There were statistical differences in basal ganglia,midbrain and brain stem in PPD and HC group(P<0.05).Under Logistic regression equation model,when the optimal threshold was 0.63,the AUC of PPD was 0.964.The sensitivity and specificity of differential diagnosis were 85.0%and 100%respectively(P<0.001).There was correlation between DTI parameters and MMSE score in locus coeruleus in PPD group(P<0.05),and the correlation coefficient of FA value in locus coeruleus(r =-0.646,P = 0.002)was the highest.Conclusions The lesions of basal ganglia,midbrain and brainstem correlated gray matter nuclei in pPD were extensive and differ-ent in degree.AD value of locus coeruleus was valuable for quantitative diagnosis of pPD,FA value of locus coeruleus could be used as a characteristic sensitive index for recognition of the severity of dysfunction in pPD patients.Multi-parameter combined diagnosis of DTI under Logistic regression model could effectively improve the diagnostic efficiency,and provide valuable reference for early diagnosis and intervention of pPD.
