Objective To summarize our experience in management of infected femoral artery pseudoaneurysm caused by addictive drugs injection.Methods Clinical data of 45 cases of infeted femoral artery pseudoaneursysm were reviewed retrospectively.When infected femoral artery pseudoaneurysm was diagnosed,the femoral artery or external iliac artery was ligated and the pseudoaneurysm was resected in all of cases.Anticoagulants and antibiotics were used after operation.Results Lower limbs were salvaged in 44 patients.The ambulation function of affected limb was fine in the short-term.One limb was amputated because of lower limb deep venous thrombosis and gangrene.Thirty-four patients(75.6%) were followed up for 3-12 months,the results were satisfactory.Conclusions Femoral artery or external iliac artery ligation is an effective procedure for management of infected femoral artery pseudoaneurysm.

Objective To investigate the efficacy of Dan'e-Fukang soft extract for dysmenorrhea associated with endometriosis.Methods A total of 88 patients with dysmenorrhea associated with endometriosis were randomly recruited into a treatment group and a control group. The patients in the control group were treated with gestrinone, while the patients in the treatment group were treated withDan'e-Fukang soft extract. The therapeutic efficacy, improvement of dysmenorrhea and drug safety after the treatment were observed in both groups.Results The total effective rate of in the treatment group(95.45%, 42/44), was apparently higher than that in the control group(81.82%, 36/44)(χ2=4.062,P<0.05). The dysmenorrhea improvement in the treatment group was better than that in the control group and also better than that before treatment in both groups(allP<0.05). The adverse reaction rate in the control group(22.73%,10/44) was higher than that in the treatment group(9.09%, 4/44)(χ2=5.906,P<0.05).ConclusionsDan'e-Fukang soft extract has a definite clinical efficacy for dysmenorrhea associated with endometriosis, can ameliorate the symptoms of dysmenorrhea.

Objective To evaluate the methods,applicability and results of cndovascular therapy for Stanford type B aortic dissection.Methods The clinical data of 36 cases of Stanford type B aortic dissection were analysed retrospectively.The stent-grafts were introduced via femoral arteriotomy.Stent-grafts were implanted to blockade tears of aortic dissection under the guidance of DSA.Results In all cases,the aortic dissection tears were blockaded,true lumens were opened,and organs function was restored.There were not complications such as internal hemorrhage due to trauma or stent displacement on CTA 3 and 12 months after endovascular therapywhile 2 cases developed new tears.The caliber of the 36 true lumens was restored to near normal.Twenty-two pseudocoeloms were obliterated,while the others were reduced is size and had varying degrees of thrombosis.Conclusions Endovascular thcrapy is safe and effectivc for the patients with Stanford type B aortic dissection.Its clinical application has a favorable outlook.

Objective: To study the expression and significance of VEGF-C, D2-40, and E-Cad in Human breast carcinoma. Methods: S-P immunohistochemical method was used to assess the expression of VEGF-C in 88 cases of infiltrating ductal carcinoma of the breast (with intact clinicopathologic and follow-up in-formation) and 54 cases of different intraductal hyperplastic lesions. The relationship of VEGF-C expression with D2-40 and E-Cadherin in infiltrating ductal carcinoma of the breast was analyzed. Results: VEGF-C ex-pression was higher in the invasive group than that in the dysplasia group and benign lesions. VEGF-C ex-pression in the metastatic group was significantly higher than that in the group without lymph node metasta-sis, indicating that VEGF-C plays an important role in the growth and metastasis of breast cancer. VEGF ex-pression in breast cancer group was higher than that in the dysplasia group and benign lesions. LVD count in the group with lymph node metastasis was significantly higher than that in the group without lymph node me-tastasis. The positive rate of E-Cad expression in the invasive group was significantly lower than that in the dysplasia group and benign lesions. VEGF-C expression was positively correlated with D2-40 expression. VEGF-C expression was negatively correlated with E-Cad expression. Conclusion: VEGF-C and D2-40 could be used for the detection of early lymphatic metastasis of breast cancer. VEGF-C and E-Cad can be used as important indices for the evaluation of the prognosis of breast cancer.

Objective To explore the association of serum cytokine levels with disease activity in patients with dermatomyositis (DM) and clinically amyopathic dermatomyositis (CADM),especially their association with skin lesions and interstitial lung disease (ILD).Methods Enzyme-linked immunosorbent assay (ELISA) and cytometric beads array (CBA)were performed to detect the serum levels of interleukin (IL)-2,IL-4,IL-6,IL-10,IL-17A,IL-18,tumor necrosis factor (TNF) and interferon (IFN)-γin 40 patients with DM or CADM,as well as in 16 health checkup examinees (healthy control group).Then,the association of serum cytokine levels with skin lesions,inflammatory biomarkers and severity of ILD was analyzed.Results The patients with DM/CADM showed significantly higher serum levels of IL-6 (37.8 ±45.8 pg/ml),IL-10 (16.1 ± 7.2 pg/ml) and IL-18 (492.0 ± 193.1 pg/ml) compared with the healthy controls (12.0 ± 2.7 pg/ml,7.7 ± 1.4 pg/ml,191.1 ± 39.2 pg/ml,respectively,all P ＜ 0.001),and there were no significant differences in the serum levels of the other 5 cytokines between the above 2 groups.The serum level of IL-6 was significantly higher in patients with elevated erythrocyte sedimentation rate (ESR) than in those with normal ESR (49.7 ± 46.8 pg/ml vs.29.1 ± 45.4 pg/ml,P =0.008).The patients with raised C-reactive protein (CRP) levels showed significantly higher serum levels of IL-6 (68.7 ± 59.7 pg/ml) and IL-18 (635.1 ± 232.8 pg/ml) compared with those with normal CRP levels (IL-6:30.6 ± 40.3 pg/ml,P =0.013;IL-18:440.2 ± 164.7 pg/ml,P =0.020).Moreover,the patients with elevated levels of lactate dehydrogenase (LDH) showed significantly higher serum levels of IL-10 (18.4 ± 6.9 pg/ml),IL-17A (19.6 ±6.7 pg/ml) and IL-18 (529.4 ± 197.2 pg/ml) compared with those with normal LDH levels (IL-10:10.7 ±4.8 pg/ml,P ＜ 0.001;IL-17A:11.4 ± 6.6 pg/ml,P =0.001;IL-18:404.9 ± 158.0 pg/ml,P =0.037).No significant difference in the cytokine levels was observed between the patients with elevated creatine kinase (CK) levels and those with normal CK levels.The patients with Gottron's papules/sign showed significantly higher serum levels of IL-18 (513.7 ± 187.2 pg/ml) compared with those without Gottron's papules/sign (297.1 ± 140.4 pg/ml,P ＜ 0.05).The serum levels of IL-10 and IL-18 were significantly higher in the patients with DM/CADM complicated by ILD (18.0 ± 6.7 pg/ml,552.3 ± 192.8 pg/ml,respectively) than in those without ILD (11.6 ± 6.5 pg/ml,351.4 ± 101.0 pg/ml,respectively,both P =0.001).Conclusion Serum levels of IL-6,IL-10 and IL-18 are highly associated with inflammatory biomarkers,skin lesions and ILD in patients with DM/CADM.

Objective: To explore the gene lifestyle interaction of ATP2B1-eNOS pathway gene polymorphisms on blood pressure. Methods: Using the convenient cluster sampling method, a total of 872 junior middle school students from 3 school in July to August 2019, were included in the final analysis. The survey included questionnaire investigation, anthropometry measurement and blood sample collection. After DNA was extracted from peripheral blood samples, the gene polymorphisms ( ATP2B1 gene rs 17249754 and rs 2070759, eNOS gene rs 1799983 and rs 2070744) were genotyped. Logistic regression model was used to analyze the association between gene polymorphism and blood pressure phenotypes. Results: The prevalence of high blood pressure was 9.52 % in adolescents(9.15% in boys and 9.87% in girls),with no significant sex difference ( χ 2=0.13, P =0.72). There were statistically significant differences between boys and girls in age, systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI) classification, birth weight, daily school physical exercise time and daily playing video games time ( P <0.05). Logistic regression analysis showed that, eNOS gene rs 2070744 polymorphism was associated with high blood pressure (HBP) under the recessive model, and the risk of HBP in CC genotype carriers were higher than that TT/TC genotype carriers ( OR=3.88, 95%CI =1.00-15.02, P < 0.05 ). The results of gene lifestyle interaction showed that ATP2B1 gene rs 2070759 polymorphism gene had an interaction with the time of physical exercise in school ( P interaction =0.05). In the subgroup with daily physical exercise time at sch ool ＜1 hour , the TT/TG genotype carriers were associated with increased risk of HBP compared with GG genotype carriers( OR= 2.65 , 95%CI =1.11-6.30, P <0.05). But in the subgroup with daily physical exercise time in school ≥1 hour, rs 2070759 was not significantly associated with HBP. Conclusion eNOS/rs 2070744 polymorphisms are associated with risk of HBP among adolescents. There is significant interaction between ATP2B1 gene rs 2070759 polymorphism and physical exercise time in school on HBP. Adolescents should spend more time on physical activity in school, which will help to maintain normal blood pressure level.

Objective: To analyze the trends and influencing factors of endurance performance of 19-22 years old college students in Hunan Province from 1985 to 2019, so as to provide objective and scientific basis for sports and health work in colleges and universities. Methods: A retrospective analysis was conducted on the data of 14 490 college students aged 19-22 in Hunan Province from 8 consecutive National Student Physical Fitness and Health Surveys conducted from 1985 to 2019. The analysis indexes were 1 000 m running for boys and 800 m running for girls. Results: From 1985 to 2019, the endurance running time of 19-22 years old Han college students in Hunan Province showed an obvious trend of decline. The 1 000 m running time of urban and rural male students increased by 41.9 and 45.4 s on average, and the 800 m running time of urban and rural female students increased by 29.5 and 30.6 s on average, respectively. Multiple linear regression analysis showed that age ( β =0.17), urban students (rural students as reference; β =0.44), GDP ( β =0.94) and urbanization level ( β = 0.44 ) were positively correlated with the average endurance running time of males. Urban students ( β =0.92), GDP ( β = 1.38 ) and Engel coefficient ( β =0.93) were positively correlated with the average endurance running time of females. BMI ( β =-0.47) was negatively correlated with the females mean time of endurance running ( P ＜0.05). Conclusion The endurance performance of Han college students in Hunan Province showed a declining trend from 1985 to 2019,which is associated with age, urban and rural distribution, regional GDP, Engel s coefficient, urbanization level and BMI. Effective measures should be taken to improve the physical quality of college students.
