Objective To evaluate the clinical outcome of stent placement in the superior vena cava (SVC) syndrome. Methods Twelve patients with stenosis of the superior vena cava and/or its main tributaries underwent placement of a self-expanding endovascular Wallstents (11 men,1 woman,mean age 51 years). Results Until death or completion of the study,the SVC syndrome was successfully controlled in 92% of the cases (11/12). There were no early procedure-related complications such as early occlusion,or migration of the stent. The recurrence rate was 16.7%. Conclusion Percutaneous venous stent placement in the superior vena cava is a relatively safe and simple procedure. In majority of cases,the symptoms of the SVC syndrome are relieved immediately and completely. Complications are rare.

Objective:To investigate the effect of pelvic motion in late pregnancy on the outcome of first trimester delivery.Methods:A total of 127 first-borns admitted to the midwifical clinic of Nanjing Maternal and Child Health Hospital from November 1, 2019 to March 10, 2020 were selected as the research objects, and they were divided into the walking group and the pelvic motion group according to the random number table method. In the end, 62 cases were included in the walking group and 65 cases in the pelvic motion group. The walking group did brisk walking in the third trimester. In the pelvic motion group, the motion in the third trimester consisted of the combined pelvic motion involving the two planes of the upright spine and the horizontal spine, and multiple peripelvic joints. The changes of fertility, birth canal and fetus before and after exercise were observed, and the outcomes of childbirth were compared between the two groups.Results:Indicators reflecting productivity: persistence time of "air bike" on the day before delivery was (27.12±7.73) seconds in the pelvic motion group and (20.56±6.60) seconds in the walking group, the difference was statistically significant ( t value was 5.12, P<0.01). The time of contractions after exercise before delivery was (269.38±123.70) seconds in the pelvic motion group and (591.29±201.82) seconds in the walking group, the difference was statistically significant ( t value was 10.89, P<0.01). The indicators reflecting the situation of the maternal birth canal were as follows: "sitting forward flexion level", pelvic motion group was (33.64±5.91) cm, walking group was (29.50±5.28) cm, the difference was statistically significant ( t value was 4.15, P<0.01). The cervical score during regular contractions was 8.01±1.69 in the pelvic motion group and 7.30±1.40 in the walking group, the difference was statistically significant( t value was 2.56, P<0.05). At the beginning of regular contractions, the proportion of fetal "occipital position" was 93.85% (61/65) in the pelvic motion group and 72.58%(45/62) in the walking group, the difference was statistically significant ( χ2 value was 10.41, P<0.01). The "no pain rate after exercise the day before delivery" was 72.31% (47/65) in the pelvic motion group and 29.03% (18/62) in the walking group, the difference was statistically significant ( χ2 value was 25.30, P<0.01). Time of the first labor was (395.84±165.24) min in the pelvic motion group and (574.35±152.23) min in the walking group, the difference was statistically significant ( t value was 6.32, P<0.01). The second stage of labor was (25.98±9.88) min in the pelvic motion group and (33.62±13.94) min in the walking group, the difference was statistically significant ( t value was 3.57, P<0.01). Conclusions:Pelvic motion in middle and late pregnancy can affect labor force, birth canal, fetus and other delivery factors, reduce movement pain and shorten the time of labor.

Objective To investigate the correlations of Mycoplasma penetrans(MPe)infection with the differentiation.invasiveness and metastasis of stomach and colorectal calFcinomas.Methods Sixty five patients with stomach carcinoma,57 patients with colorectal carcinoma and 80 healthy individuals as controls were enrolled in this study.MPe was isolated and then confirmed by PCR.χ2 test was performed to analyze the correlations of MPe infection with the differentiation,invasiveness and metastasis of carcinoma.Results The rate of MPe isolated from stomach carcinoma group(41/65,63.1%)was significantly higher than that from stomach ulcer group(χ2=38.2,P＜0.01).The rate of MPe isolated from eolorectal carcinoma group (1/20,5%)was also significantly higher than that from colorectal polyps group(χ2=21.2,P＜0.01).The proportion of poor differentiation and the invasiveness in MPe positive stomach carcinoma group were significantly higher than those in MPe negative group(χ2:33.4 and 25.0.P＜0.01).The proportion of poorly differentiation and lymphatic metastasis(N3)in MPe positive colorectal carcinoma group were significantly higher than those in MPe negative group(χ2=34.4,P＜0.01).Conclusion Differentiation,invasiveness and metastasis are highly correlated with MPe infection in stomach and colorectal carcinomas.

Objective To investigate the effects of human S100A6 on β-catenin in human osteosarcoma cell lines MG63 and U2OS. Methods Cell lines MG63 and U2OS were infected by recombinant adenoviruses carrying human S100A6 and its siRNA gene, AdS100A6 and AdSiS100A6 respectively, to up-regulate and down-regulate the ex-pression of S100A6. Then RT-PCR, Western blot and immunocytochemistry were used to detect mRNA and protein (level and/or distribution) of β-catenin. Results In both cell lines, with up-regulated S100A6, expression of β-catenin mRNA and protein increased(P <0. 05) and β-catenin protein increase was more obvious in nuclear than in cytoplasma; while down-regulating S100A6, both the mRNA and protein level of β-catenin decreased (P<0. 05) ; β-catenin protein decrease was more obvious in nuclear than in cytoplasma, too. Conclusion In-creasing Wnt/β-catenin signaling activity may be a mechanism that S100A6 involves in tumor development.

Objective　To compare the Immunoreactivity of various HEV Antigen with Anti-HEV IgM. Methods Solid-phase enzyme immunoassay( EIA ) was developed for detecting anti-HEV IgM by using synthetic peptides E30, E42, E33, and recombinant antigen from HEV ORF-2. Results Of 60 anti-HEV positive sera by using E30, E42, E33 and recombinant antigen as coating antigen, Anti-HEV IgM positive rates were 76.7%, 26.6%, 18.3% and 66.7% respectively. In Acute-phase and convalescence-phase sera of the patients with Hepatitis E, Anti-HEV IgM positive rate was 90% and 3.3% respectively. Conclusions The HEV E30-based EIA will be very useful in the early diagnosis of Hepatitis E.
