ObjectiveTo investigate the characteristics of pelvic floor structure and electrophysiology in female patients with stroke. MethodsFrom June to December, 2020, 21 female inpatients with stroke in Zhongda Hospital, Southeast University (stroke group) were divided into urinary incontinence (UI) group (n = 6) and non-urinary incontinence (NUI) group (n = 15), and other 20 healthy subjects were as control group. They were observed with pelvic floor ultrasonography and pelvic floor surface electromyogram. ResultsAverage electromyography, integral electromyography, root mean square, mean power frequency and median frequency decreased in UI and NUI groups compared with those of the control group (P < 0.05), but there was no significant difference between UI group and NUI group (P > 0.05). Bladder neck position, bladder neck angle, bladder neck mobility, urethral rotation angle; and anteroposterior diameter, left-right diameter and area of levator ani muscle hiatus after Valsalva's action were all not different among three groups (F < 2.484, P > 0.05). ConclusionThe activities of pelvic floor muscles decrease in female patients with stroke, without obvious changes of pelvic floor supporting structures, whatever UI.
摘要
Compared with distal gastrectomy, pylorus-preserving gastrectomy is less invasive which can decrease incidence of dumping syndrome, diarrhea and body weight lost, cholecystitis and gallstone, reflux gastritis and esophagitis and remnant gastric cancer. Based on new Japanese Gastric Cancer Treatment Guideline and new progression in the world, we give a review mainly basic characteristics, indications, operation details and short- and long-time outcomes after pylorus-preserving gastrectomy.

Objective To observe the inhibitory effect of DPC4 gene on growth of pancreatic carcinoma in vitro. Methods The human DPC4 cDNA was subcloned to the retroviral vector pLXSN and then packaged with GP+E86 and PA317 packaging cells respectively. AntiG418 clones were acquired and named as PA317/ pLXSN DPC4+ cells. The DPC4 gene was restored to the human pancreatic cancer cell line BxPC-3 by the infection of the pLXSN/DPC4 and then had a stable expression after antiG418 selection, which was demonstrated by RT-PCR and Western blot. The inhibitory action of DPC4 gene expression on growth of these daughter cells was observed.Results DPC4/Smad4 gene integration in GP+E86、PA317/ pLXSN DPC4+ cells was detected by polymerase chain reaction. The BxPC-3 cells, which were null for DPC4, had stable expression of DPC4 after the infection of the pLXSN/DPC4. The expression of DPC4 gene was able to inhibit the growth of these cancer cells in vitro and downregulate the VEGF mRNA level.Conclusions This study suggested that there can be marked inhibition of growth and angiogenetic ability of pancreatic cancer cells after infection by retrovirus vector containing DPC4.
