RESUMO
Objective:To systematically compare the analgesic efficacy of pericapsular nerve group (PENG) block and fascia iliaca compartment block (FICB) after hip fracture surgery.Methods:Databases including Pubmed, Embase, Cochrane, CNKI, Wanfang and VIP were searched for randomized controlled trials involving comparison of the analgesic efficacy of PENG block and FICB after hip fracture surgery from inception to August 2022. The primary outcome was the postoperative pain score, and the secondary outcome was the amount of postoperative analgesics and incidence of postoperative adverse reactions. The data were analyzed using Revman 5.4 software.Results:Eight studies were included ( n=374), and the pain score at rest 30 min after block was significantly lower in PENG group than in FICB group ( MD=-0.35, 95% CI -0.60--0.11, I2=14%, P<0.05). There was no statistically significant difference between PENG group and FICB group in pain scores at rest and during activity at 6, 12, 24 and 48 h after operation ( P>0.05). Compared with FICB group, the amount of analgesics used was significantly reduced at 24 and 48 h after operation in PENG group ( MD=-9.10, 95% CI -19.11-0.91, I2=95%, P<0.05). There was no statistically significant difference in the incidence of adverse reactions after operation between the two groups ( P>0.05). Conclusions:PENG block provides better efficacy when used for analgesia following hip fracture than FICB.
RESUMO
The histopathological growth pattern (HGP) of colorectal cancer liver metastasis (CRLM) is correlated with the prognosis of patients. Patients with desmoplastic HGP have a better prognosis. The latest international scoring guidelines have modified the cut-off value of HGP, and divides it into two types: complete desmoplastic HGP and incomplete desmoplastic HGP. However, the relationship between the HGPs and the treatment response to systemic treatment is still unclear. It is necessary to develop non-invasive methods to evaluate changes in HGP during treatment in the future. This paper reviews the new scoring consensus and clinical applications of HGP in CRLM.
RESUMO
Objective To explore the influence of lower concentration of cell free fetal fraction DNA in maternal plasma on non-invasive prenatal test(NIPT) .Methods A total of 3240 pregnant women accepted NIPT in Foshan Maternal and Children′s Hos-pital from April ,2015 to March ,2016 were analyzed retrospectively ,and 150 samples of which were male fetus judged by Z score of Y chromosome and the cell free fetal fraction DNA were lower than 8% were selected .The cell free fetal fraction DNA were in-creased by agarose gel electrophoresis ,then conducted NIPT ,compared with the results of aneuploidy screening .Results The cell free fetal fraction DNA were increased from 5% to 9 .2% by agarose gel electrophoresis .The result of NIPT after increasing fetal fraction was consistent with it before .Conclusion Concentration of cell free fetal fraction DNA has no influence on the result of NIPT when cell free fetal fraction DNA is above 5% .
