Objective:To explore predictive value of quantitative evaluation of shear wave ultrasonic elastography(SWUE)on the hardness of soleus muscle for short-term progress of the distal deep venous thrombosis(DVT)of lower extremities.Methods:A total of 100 DVT patients who admitted to the second hospital of Zhangjiakou from January 2021 to December 2023 were retrospectively selected,and they were divided into group with progress(n=45)and group without progress(n=55)according to the results of the ultrasonic reexamination of blood vessels of lower extremities at the 2nd week after they were confirmed.Univariate and multivariate logistics regression analysis were used to analyze the influencing factors for short-term progress of DVT patients.Receiver operating characteristic(ROC)curve was drawn to analyze the applied value of SWUE quantitative assessment for the hardness of soleus muscle in predicting the short-term progress of DVT patients.The coagulation indicators of the two groups before and after treatment were further compared.Results:There were no significant differences between the two groups in cholesterol,neutrophil count,platelet count,central venous catheterization,bed rest,history of thrombosis,injury of vascular wall,and history of surgery for lower limb(P>0.05).The average hardness values of soleus muscle of group with progress and group without progress were respectively(6.46±1.15)kPa and(5.42±1.13)kPa,and the difference of that between two groups was significant(t=4.542,P<0.05).Multivariate logistics regression analysis showed that hardness of soleus muscle was the independent risk factor for short-term progress of DVT patients(OR=3.135,P<0.05).The results of ROC analysis showed that the area under curve(AUC)value of the hardness of soleus muscle in predicting short-term progress of DVT patients was 0.9074(95%CI:0.8175～0.9972),and the best cutoff value was 0.70,and the sensitivity and the specificity were respectively 78.26%and 91.30%at this time.Before treatment,there were no significant differences in the comparison of prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT)and D-dimer(D-dimer)between the two groups of patients(P>0.05).After treatment,the PT,APTT and TT levels of patients in the group without progress were respectively higher than those in the group with progress,and the D-dimer level was lower than that in the group with progress,there was a statistically significant difference between the two groups(t=3.568,15.176,4.091,9.981,P<0.05),respectively.Conclusion:SWUE quantitative evaluation for the hardness of soleus muscle has a favorable predictive value for the short-term progress of distal DVT of lower extremities,which is contribute to early find the DVT short-term progress,thus can timely adopt intervention measure,and reduce the risk of complication,and improve the prognosis.

Objective To investigate the clinical application value of peripheral blood lymphocyte subsets expression levels in autoimmune disease(AID) among the patients with antinuclear antibody(ANA) positive .Methods 200 patients with ANA positive and 196 patients with ANA negative were selected as the experimental group and control group respectively .The experimental group adopted indirect immunofluorescence assay (IFA) and immunoblotting assay(LIA) for detecting ANA ,moreover divided into the IFA group and LIA group according to the detection results .Meanwhile the flow cytometry was adopted to detect peripheral blood T lymphocytes ,helper T lymphocytes ,cytotoxic T lymphocyte ,NK lymphocytes and B lymphocytes absolute values of each group .The detection results were statistically analyzed .Results Helper T lymphocytes ,NK lymphocytes and B lymphocytes absolute values in the experimental group were significantly lower than those in the control group ,the differences were statistically significant(P＜0 .01);in the experimental group ,helper T lymphocytes and NK lymphocytes absolute values in the IIF group were significantly lower than those in the LIA group ,the differences were statistically significant (P＜0 .01) .Conclusion Peripheral blood lymphocytes subsets can serve as the important detection indicators during the diagnosis and treatment process of AID .

ObjectiveTo study the effects of angiogenesis on the development of endometrial carcinoma. Methods Hysterectomy specimens were stained immunohistochemically by the marker of factor Ⅷ-related antigen for endothelium vessels in normal controls, patients with endometrial hyperplasia and with endometrial carcinoma. Results The microvascular density(MVD) in tumour increased gradually from normal endometrium to endometrial hyperplasia and to endometrial carcinoma(P<0.01). MVD correlated with the mvometrial invasion, histologic grades and the stages.ConclusionMYD in endometrial hyperplasia increases. MVD can be used as a prognostic factor.
