RESUMO
Objective: To explore the clinical value of ultrasound-guided radiofrequency ablation in the treatment of retroperitoneal tumors. Methods: The clinical data of 13 patients with retroperitoneal tumors treated with ultrasound-guided radiofrequency ablation in the First Affiliated Hospital of Zhengzhou University from January 2018 to January 2020 were analyzed retrospectively. The ablation effect was evaluated and the postoperative complications were observed. The changes of tumor volume before and after radiofrequency ablation were compared. Results: The symptoms of pain and dyspepsia were significantly improved after radiofrequency ablation, and the hospital stay was (9.2±2.9) days. The tumor was ablated completely in 10 cases, tumor residual in 1 case and tumor metastasis in 2 cases. One patient had postoperative duodenal perforation complicated with intra-abdominal infection, and no serious complications occurred in other patients. There were 20 lesions in 13 patients. The maximum diameter of 20 lesions before operation and 1, 3, 6 months after operation were (39.5±15.9) mm, (30.6±4.9)mm, (15.6±7.7) mm and (9.9±3.1) mm, respectively, the maximum diameters of 1, 3 and 6 months after operation were smaller than that before operation (P<0.05). Conclusion: Ultrasound-guided radiofrequency ablation is a real-time, accurate, safe and effective minimally invasive treatment with few complications, and has a high clinical value for retroperitoneal tumors.

OBJECTIVE@#To decipher the possible mechanisms of Sinomenium Acutum (SA) in treating diseases by a bioinformatics method.@*METHODS@#SA ingredients were searched according to Chinese Pharmacopoeia, Chinese Medicine Dictionary and Traditional Chinese Medicines Database (TCMD). Active compounds and target proteins of SA were acquired through the Pubchem platform. Pathway, network and function analyses of SA were performed with ingenuity pathway analysis (IPA), a bioinformatics analysis platform. Disease, biofunction-target networks were established with Cytoscape.@*RESULTS@#Eighteen ingredients from SA were obtained. Seven active ingredients with 31 active target proteins were acquired according to PubChem Bioassay test. By IPA analysis, 277 canonical pathways belonging to 17 function categories were collected, 23 kinds of diseases, 21 categories bio-functions were obtained. Based on P value, calculated by IPA, the top 5 significant pathway of SA targets include phosphatidylinositol 3 kinase/Akt (PI3K/Akt) signaling, prostate cancer signaling, macrophage migration inhibitory factor (MIF) regulation of innate immunity, Guanosine-binding protein coupled receptor (GPCR) signaling, and ataxia telangiectasia mutated protein (ATM) signaling. Disease and bio-function network analysis indicated that mitogen activated protein kinase 1 (MAPK1), MAPK3, p65 nuclear factor κB (RELA), nuclear factor of κB inhibitor alpha (NFκBIA), interleukin 1β(IL-1β), prostaglandin G/H synthase 2 (PTGS2) and tumor protein 53 (TP53) were the critical targets in various diseases treated by SA.@*CONCLUSION@#In the different view of target, pathway, disease and bio-function, inflammation was found to be a central theme in many chronic conditions. SA could be used not only as an anti-inflammatory agent, but also for the treatment of cancers, neurological diseases, psychological disorders and metabolic diseases.

RESUMO
Objective@#To investigate the prevalence of urogenital tract infections with Ureaplasma urealyticum (UU) and human papilloma virus (HPV) in males of reproductive age and the associated factors.@*METHODS@#Using the multi-stage cluster sampling method and a structured questionnaire, we conducted an investigation among 18-50 years old males in Songjiang District, Shanghai, from August 2016 to July 2018. We collected secretory specimens from the urogenital tract of the subjects and detected the infections of UU and HPV by laboratory examination.@*RESULTS@#Among the 621 males included in this study, 279 (44.93%) were found infected with UU, 18 (2.90%) with HPV, and 15 (2.42%) with both UU and HPV. Univariate analysis showed that smokers had a higher rate of UU infection (50.54% [140/277]) than non-smokers (40.41 [139/344]), and those with senior high school or secondary technical school education had a higher rate of HPV infection (4.84% [12/248]) than others (1.61% [6/373]). Binary stepwise logistic regression analysis revealed a higher risk of UU infection in the subjects with junior high school or lower education than in others (OR = 0.61, 95% CI: 0.39-0.96) as well as in smokers than in non-smokers (OR = 1.46, 95% CI: 1.01-2.01).@*CONCLUSIONS@#The prevalence of UU infection is high, while that of HPV is low among men of reproductive age in Songjiang, Shanghai. The screening of UU infection should be enhanced among men of reproductive age, especially among smokers and those with lower education.
RESUMO
Objective To provide a basis to satisfy the need for family planning of women of reproductive age,according to the analysis and estimation of family planning status of married or in union women of reproductive age among China,Japan,India,South Africa and the United States of America.Methods U test and Chi-square test were applied to analyze the current situation (1970-2016) and tendency (2017-2030) of family planning indicators of the five countries from 1970 to 2030,which were selected from open database of World Contraceptive Use 2016.Results Compared with the family planning status in 1970,there was a significant change in total demand for family planning,contraceptive prevalence and unmet need for family planning (P<0.001).To be specific,in 2016,contraceptive prevalence of married or in-union women of reproductive age in China,Japan,India,South Africa and the United States of America was 83.35%,59.9%,56.4%,64.9% and 73.7%,respectively;unmet need for family planning was 3.8%,13.1%,15.5%,12.2% and 7.2%,respectively.Besides,contraceptive methods composition in the five countries were changed in 2016 (P<0.001) and the prevalence of modern methods was higher than traditional methods.Meanwhile,the percentage of demand for family planning satisfied with modern methods were increasing from 1970 to 2016.On the other hand,the projections of total demand for family planning,contraceptive prevalence,unmet need for family planning,composition of contraceptive methods and unmet need for modern methods would change from 2017 to 2030 (P<0.001).It was estimated that,in 2030,China would have the largest number of people using contraceptive methods and India would have the largest number of people with unmet need for family planning.Moreover,China and India might be the countries with most users of modern methods,and India might be associated with the most users of traditional methods.Conclusions Considering current and projected status of huge total demand for family planning,high contraceptive prevalence,low unmet need for family planning,it is essential to supply approximate contraceptive methods.
RESUMO
Human papillomavirus (HPV) infection is one of the worldwide sexually transmitted diseases (STD), and the DNA of HPV can exist in the normal epithelium of reproductive organs of both men and women. Because the majority of HPV infections are asymptomatic, healthy HPV-carriers become the main source of the infection. Studies show that HPV infection in men is correlated with STD, infertility, tumor of reproductive organs, and infection in the sexual partners. Therefore, measures should be taken to reduce male HPV infection, including circumcision, fewer sexual partners, and condom use.

This study was purposed to evaluate the outcome of acute myeloid leukemia patients treated with related peripheral blood hematopoietic stem cell transplantation (PBHSCT) and analyse the potential prognostic factors. A total of 64 acute myeloid leukemia patients treated with related peripheral allo-HSCT from march 2008 to august 2012 in our hospital were enrolled in the analysis. All the patients received either HLA-matched related or mismatched related donor mobilized peripheral blood stem cells. All the patients were followed up and evaluated for overall survival (OS), leukemia-free survival (LFS) and relapse rate (RR) , and the potential prognostic factors well analyzed. The results showed that the 3 year OS , LFS and RR were 61.9%, 52% and 39.1% respectively. Univarite analysis demonstrated that the disease status before transplantation (P < 0.01) , donor type (P < 0.01), white blood cell count at initial diagnosis (P < 0.05) are related with outcome, and severe aGVHD has some influence on the outcome (P > 0.05) . Multivariate analysis indicated the status of disease before transplantation, donor type, severe aGVHD are the most important prognostic factors. It is concluded that the related PBHSCT is effective treatment method for AML patients, recurrence is the main reason for the failure after transplantation, disease status before transplantation, donor type, and severe aGVHD are independent prognostic factors.

Objective To explore the effects of high birth weight (HBW) on blood pressure (BP) during childhood.Methods A total of 1435 couples with high or normal birth weight were selected from a birth cohort who were born between 1993 and 1995 in Wuxi,China and,followed between 2005 and 2007.A questionnaire survey was conducted,with their height,weight and blood pressure measured.Results The medians of systolic blood pressure (SBP) and diastolic BP (DBP)of HBW group were 100 mm Hg (Q1-Q3∶90-110 mm Hg),64 mm Hg (Q1-Q3∶60-70 mm Hg) in the high birth weight group,respectively,while they were 100 mm Hg (Q1-Q3∶90-108 mm Hg),62 mm Hg (Q1-Q3∶60-70 mm Hg) in the normal weight group.No statistical significant difference was found between the exposed and unexposed groups.The proportion of elevated BP,including prehypertension and hypertension,in exposed group was 13.66%,a bit higher than that (11.57%) of the unexposed group (P = 0.055).The relative risk (RR) of HBW on elevated BP was 1.06 (0.92-1.21),after adjusted the following parameters as BMI in childhood,sex,age during the follow-up period,age of mother at delivery,gestational age,type of feeding at infancy,dietary habit as well as the frequencies of exercise during childhood.Conclusion No statistically significant correlation was found between high birth weight and blood pressure of children.
RESUMO
This study was purposed to investigate the significance of using (FCM) flow cytometry for detection bone marrow involvement by lymphoma cells in untreated patients with B cell non-Hodgkin's lymphoma (B-NHL). Bone marrow samples of 54 patients with B-NHL were analyzed by flow cytometry, morphological method and molecular biology technique. Bone marrow involvement was diagnosed based on the results of morphology, FCM and molecular biology. The results indicated that the positive ratios of bone marrow involvement were different detected by three methods, the most sensitive method was FCM (positive rate was 27.5%), the moderately sensitive method was molecular biology (positive rate was 22.2%), the inferior method was morphology method (positive rate was 5.6%). Combined with three methods, the positive rate increased to 38.9%. The monoclonal B lymphocytes were detected by FCM in fourteen patients, the ratios of kappa light chain/lambda light chain were far beyond the diagnostic threshold. Even in patients with early stage, lymphoma cells still could be detected by FCM in involved bone marrow. Monoclonal B lymphocytes were detected by FCM in three patients who were diagnosed bone marrow involvement by morphological method. The concordance between FCM and molecular biology was relatively high (70.4%, p=0.14). It is concluded that the detection of monoclonal B lymphocytes by using FCM has high sensitivity and accuracy in patients with B-NHL. Evaluation whether the bone marrow has been involved by lymphoma cells should be recommend to every patient with B-NHL before chemotherapy and every disease stages. Combined application of FCM and molecular biology method would enhance diagnostic efficacy.
