RESUMO
Objective To compare the parameters of bilateral tubal ligation by LESS and multi-incision laparoscopy and their prognosis of IVF-ET. Methods From Jun. 2016 to Dec. 2017,32 patients underwent LESS bilateral tubal ligation and 60 patients under-went multi-incision laparoscopic bilateral tubal ligation were enrolled. The demographic data ,operative parameters ,and postoperative prognosis of IVF- ET in the two groups were summarized and compared. Results The mean operating time in LESS group was prolonged and its operative hospital stay was significantly decreased compared to multi-incision laparoscopic group. No significant difference was observed in the intraoperative blood loss in two groups. Moreover,no significant differences were found in the AFC,AMH,Gn stimulation days,total Gn dosage,Ovum number,good quality embryo rate,embryo implantion rate,clinical pregnancy rate and early spontaneous abortion rate in two groups. Conclusions For experienced laparoscopic surgeons,LESS is a safe and feasible procedure with similar perioperative outcomes to multi-incision laparoscopic surgery.
RESUMO
Objective To investigate the expression and clinical significance of CXC chemokine receptors 1 and 2 (CXCR1 and CXCR2) and CXCL8 in peripheral blood mononuclear cells (PBMCs) and liver biopsy tissues from patients with primary hepatocellular carcinoma (PHC).Methods Serum specimens were collected from 36 patients with PHC, 30 patients with liver cirrhosis and 28 healthy subjects.Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to measure the expression of CXCR1, CXCR2 and CXCL8 at mRNA level in PBMCs.Streptavidin-perosidase (SP) immunohistochemistry was used to detect the expression of CXCR1, CXCR2 and CXCL8 at protein level in liver biopsy tissues.Levels of C-reactive protein (CRP), alpha-fetoprotein (AFP) and ferritin (FER) in the serum specimens were detected by chemiluminescence immunoassay.Then the correlations between these markers were analyzed.Results All of the results showed that the expression of CXCR1, CXCR2 and CXCL8 at mRNA level in PBMCs from the PHC group were higher than those of the healthy control group (P<0.01) as well as those of the liver cirrhosis group (P<0.05).Up-regulated expression of CXCR1, CXCR2 and CXCL8 in patients with PHC were associated with the depth of tumor invasion, lymph node or distant metastasis, clinical stage and levels of CRP, AFP and FER in serum (P<0.05).The expression of CXCR1, CXCR2 and CXCL8 at protein level in liver biopsy tissues were also significantly increased in the PHC group in comparison with those of the healthy control group as indicated by the result of SP immunohistochemistry (P<0.05).Conclusion Levels of CXCR1, CXCR2 and CXCL8 in the patients with PHC are significantly increased and positively correlated with the levels of AFP, FER and CRP in serum, suggesting that the signal transduction process mediated by CXCR1, CXCR2 and their common ligand CXCL8 may play a key role in the pathological process of PHC.This study may provide a potential new strategy for immune intervention in hepatocellular cancer.
RESUMO
Objective To explore the diagnostic value of tumor markers of CEA,CA153,TPS,Fer and CYFRA21-1 level in postoperative metastasis of breast cancer.Methods After 3-year follow-up for 578 patients with primary breast cancer from 2012 to 2014,we chose 42 patients with metastasis as metastasis group,and another 42 cases without as non-metastasis group.Level of CEA,CA153,TPS,Fer and CYFRA21-1 was detected using chemiluminescence and the difference of CEA,CA153,TPS,Fer and CYFRA21-1 level in 2 groups was compared.Pearson correlation test analysis and ROC curve test were performed for data analysis.Results Serum CEA,CA153,TPS,Fer and CYFRA21-1 levelq6.11 ± 1.87)ng/mL,(26.97 ± 9.52) U/mL,(155.95 ± 22.03)U/L,(173.08 ± 19.87)ng/mL and (18.98 ± 7.33)ng/mL respectively increased in metastasis group when compared with those in non-metastasis group (5.33 ± 1.85)ng/mL,(23.34 ± 8.30)U/mL、(133.22 ± 19.09)U/L,(142.29 ± 22.59) ng/mL and (6.76 ± 1.59)ng/mLrespectively and the change of TPS,Fer and CYFRA21-1 was more obvious and the difference was statistically significant (P ＜ 0.05).There was no significant correlation among serum TPS,Fer and CYFRA21-lin metastasis group.The area under ROC curve of CYFRA21-1 was 0.903,followed by Fer (0.849) and TPS (0.791) and in the diagnosis of metastasis of breast cancer,CYFRA21-1 has great diagnostic value.Conclusions The increase of serum TPS,Fer and CYFRA21-1 level is closely associated with postoperative metastasis of breast cancer and CYFRA21-1 has great diagnostic value for monitoring postoperative metastasis of breast cancer.
RESUMO
Objective To study the diagnostic value of serum α-L-fueosidase (AFU), transforming growth factor alpha(TGF-α)and ferritin (Fer) in primary hepatic carcinoma (PHC). Methods AFU and Fer in the serum were studied in 36 patients with benign hepatism and 56 patients with low concentration AFP of PHC hepatic carcinoma by automatic biochemistry analyzer Roche Modular. ELISA was used to assay the degree of TGF-α The sensitivity and specificity of AFU, TGF-α and Fer for low expression AFP of PHC were evaluated by ROC curve. Results The serum AFU, Fer and TGF-α levels were all significant difference in the patients than those in controls (P <0.05). The area under ROC curve of these indexes in descending order was AFU (0.707), TGF-α (0.677) and Fer (0.592). The diagnostic sensitivity of Fer was lower than AFU and TGF-α in diagnosis of AFP lowly expression PHC. The ratio showed AFU better than TGF-α The diagnostic specificity of AFU (64 %) was higher than that of TGF-α (61%) when TGF-α and AFU was at the same diagnostic sensitivity (64 %). Conclusion AFU is more valuable than Fer and TGF-α for negative or AFP lowly expression PHC, meanwhile it has much more accuracy.
RESUMO
A series of research results on the influence of soybean to the bioavai?lability of non-heme iron in diet are reported. It is proved that Soybean and some of its products decrease the bioavailability of non-heme iron in diet by human observation and animal experiments. This result is due to insufficient control over the inhibitors and utilization of the enhancers of the bioavailability of iron in soybean itself.Experiments show that through some special treatment processes such as sprouting, fermenting and making bean curd, the above disadvantages may be effectively reduced and remarkably increase the bioavailability of the non-heme iron. These conclusions possess both theoretical and practical meaning for full utilization of soybean protein and effective prevention of iron deficiency anemia.
