0.05.Conclusions The UF effectively removed BUN in sheep with low flow VV-ECMO.The application of UF didn't cause blood shunt in ECMO.The low flow VV-ECMO effectively eliminated carbon dioxide and rerformed oxygenation.

The purpose of this study was to investigate the impact of leucine-rich repeats and immunoglobulin-like domains 3 (LRIG3) on the biological features of bladder cancer cell lines. The plasmids of over-expressed LRIG3 and the blank plasmid serving as control were transfected into the bladder cancer cell lines, T24, EJ and BIU-87, and the expression levels of LRIG3 mRNA and protein were detected by using real-time PCR and Western blotting. The changes in the cell cycle and apoptosis were examined by using flow cytometry. The invasive ability was measured by Transwell assay, and CCK-8 assays were used to measure the proliferation of cells. As compared with the control group, the LRIG3 mRNA and protein expression levels in LRIG3 cDNA-transfected group were raised significantly (P<0.05). The average number of cells with up-regulated LRIG3 passing through the inserted filter was decreased significantly as compared with the control group (P<0.05). Up-regulation of LRIG3 also could inhibit proliferation and induce apoptosis of T24, EJ and BIU-87 cells. Except BIU-87, the T24 and EJ cells transfected with LIRG3 cDNA were arrested in G(0)/G(1) phase compared to the control group (P<0.05). In conclusion, the over-expression of LRIG3 could influence the cell cycle and invasion, inhibit proliferation and induce apoptosis in the three bladder cancer cell lines.

Objective To explore the effect of overwork (OW) on extracellular matrix of arterial vessel wall in rats. Methods Random number grouping method was employed to assign 18 Sprague-Dawley rats into three groups(n=6):the control group(no special treatment),group OW(forced swimming twice a day for 15 days),and sleep deficiency(SD)+OW group(in addition to forced swimming twice a day,the rats were put on the platforms in water to limit sleep for 15 days).On the 16th day,the abdominal aorta and common carotid artery were collected after blood sampling from heart under deep anesthesia.A part of the abdominal aorta sample was taken for Masson staining of collagen fiber,and Verhoeff-Van Gieson staining was carried out for the elastic fiber of common carotid artery.Image J was employed for the quantitative analysis of collagen fiber and elastic fiber content.The expression of collagen 1(Col-1) protein was quantified by immunohistochemistry and the ultrastructure of vascular matrix was examined by transmission electron microscopy.The other part of the abdominal aorta sample was used to determine the mRNA levels of matrix metalloproteinase(MMP)-1,MMP-2,MMP-9,tissue inhibitor of metalloproteinases-1(TIMP-1),and Col-1 by quantitative real-time polymerase chain reaction. Results Compared with that in control group,the content of collagen fiber in groups OW and SD+OW had no significant change(all P>0.05);the content of elastic fiber in groups OW and SD+OW decreased(all P<0.001) and had no significant difference between each other(P>0.05).The vascular vessel wall of group OW showed slight fiber breakage,while that of group SD+OW presented wormhole-like or spongy fiber fragmentation.The mRNA levels of MMP-1 and MMP-2 in groups OW and SD+OW had no significant difference between each other(P>0.05) but were higher than that in control group(all P<0.001).The mRNA levels of MMP-9 and TIMP-1 had no significant difference among the three groups(all P>0.05).Groups OW and SD+OW had lower mRNA level(all P<0.001) and protein level(all P<0.001) of Col-1 than control group,while the mRNA and protein levels of Col-1 had no significant difference between groups OW and SD+OW(P>0.05). Conclusion OW can reduce the content of Col-1 and elastic fibers in the extracellular matrix of arterial vessels,destroy the elastic lamina of vascular wall,up-regulate the expression of MMP-1 and MMP-2,thereby injuring arterial vessels.

OBJECTIVE: To evaluate the effectiveness and safety of Zhenqi Buxue Oral Liquid (ZQ), progesterone capsules, and their combination in treating oligomenorrhea and hypomenorrhea with qi-blood and Kidney (Shen) essence deficiency. METHODS: This was a prospective, randomized, multi-center controlled trial between June 2022 to December 2022. Ninety-six oligomenorrhea and hypomenorrhea patients with qi-blood and Shen essence deficiency were randomly assigned to receive ZQ (ZQ group, 29 cases), progesterone capsules (PG group, 32 cases), or the combined Chinese and Western medicine (COM group, 31 cases) at a ratio of 1:1:1. Patients in the ZQ or PG group took daily 10 mL twice a day of ZQ or 200 mg once a day of progesterone capsules for 10 consecutive days on day 15 of the menstrual cycle respectively, and patients in the COM group received the same ZQ combined with progesterone capsules. The treatment course lasted for 3 months and follow-up was performed at 1 and 3 months after the end of treatment. Primary endpoint was the menstrual Traditional Chinese Medicine Syndrome Scale (TCMSS) scores. Secondary endpoints included pictorial blood loss assessment chart (PBAC) scores, clinical efficacy rate, 36-item Short Form Health Survey (SF-36) scores, sex hormones and thickness of endometrium. Adverse events (AEs) were recorded. RESULTS: TCMSS scores after 1- and 3-month treatment in all groups were significantly lower than those at baseline (P<0.05). Only TCMSS scores after 3-month treatment in the ZQ and COM groups continuously decreased compared with those after 1-month treatment in the same group (P<0.01). TCMSS scores after 3-month treatment in the ZQ and COM groups were significantly lower than those in the PG group (P<0.05, P<0.01). Compared with baseline, PBAC scores in the ZQ and COM groups after 3 months of treatment were also significantly higher (both P<0.01). The total effective rates of TCM syndrome of 3-month treatment were significantly improved in all groups compared with that after 1 month of treatment (P<0.05). The total effective rate of the COM group was the highest in the 3rd month of treatment and significantly higher than that of PG group alone (P<0.05). Compared with baseline, only the SF-36 scores of COM group were significantly improved after 3 months of treatment (P<0.05). No serious adverse reactions were observed after treatment. CONCLUSIONS The combination of ZQ and PG, or ZQ only had better effects on reducing TCMSS scores compared with PG, and COM showed the higher total effective rate compared with monotherapy. Besides, COM could effectively improve menstrual blood loss and quality of life. ZQ combined with PG may be an effective and safe option for oligomenorrhea and hypomenorrhea patients with qi-blood and Shen essence deficiency.

Bladder cancer remains a commonly diagnosed malignancy worldwide, bringing huge economic burden and high morbidity for patients. Assessment of prognostic significance of lymphovascular invasion (LVI) is a critical issue in the surgical management of bladder cancer after transurethral resection or radical cystectomy. A systematic search of PubMed, Embase and Cochrane Library was performed up to Oct 10, 2014 to identify eligible studies. Outcomes of interest were collected from studies comparing overall survival (OS), cancer specific survival (CSS) and recurrence free survival (RFS) in patients with the LVI. Results of studies were pooled, and combined hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) for survival were used as the effect size estimation. Funnel plots were done to show the publication bias, while the forest plots and subgroup analyses were used to limit the heterogeneity. A total of 20 studies (10 663 patients) met the eligibility criteria and were included for this meta-analysis. Our pooled results showed that there were significant differences in OS (pooled HR, 1.71; 95%CI, 1.52-1.92; P<0.00001), CSS (pooled HR, 2.25; 95% CI, 1.80-2.81; P<0.00001) and RFS (pooled HR, 1.91; 95% CI, 1.57-2.32; P<0.00001) between the patients with LVI and the patients without LVI. There were significant heterogeneities observed in the studies concerning the relationship between LVI and CSS, RFS. There was no clear evidence of publication bias. When tumor stage was beyond T3, LVI lost its predictive value for CSS and RFS. For the patients who had negative lymph nodes, LVI was still an adverse predictor. Our pooled results demonstrate that LVI indicates poor prognosis of patients with bladder cancer after surgical procedures, and it can be of particular importance in clinical practice. However, these results need to be further confirmed by more adequately designed prospective studies.
