Matrix metalloproteinases-9(MMP-9) is an important gene in coloreetal cancer occurrence and development.MMP-9 can induce cell proliferation,angiogenesis and neoplasm infiltration,and then leads to coloreetal cancer invasion and metastasis.MMP-9 can not only play the role individually in coloreetal canccr invasion and migration,but also can cooperate with other genes.MMP-9 is a key protease in terminal metastasis of coloreetal cancer.

chronic cervicitis(0%),(P=0.000).The positive rates of EPMMPRIN overexpression in metastatic lymph nodes was 54.5%(12/22),no difference was found from corresponding primary tumor(72.7%,P=0.210).But EMMPRIN overexpression in primary tumor was related to lymph node metastasis(P=0.026),no relationship was found between EMMPRIN expression and other clinical-pathological parameters.Univariate analyses revealed that EMMPRIN expression did not correlate to tumor-specific survival.In contrast,lymph vascular space invasion,deep stromal invasion and lymph node metastasis were significantlyassociated with poor prognosis.In multivariate analysis,lymph-node metastasis was the independent prognostic factor for tumor-specific survival(P=0.006;HR=0.038;95% confidence interval,0.0190.763).Conclusion:EMMPRIN overexpression may play an important role in progression of human cervical cancer,and in the development of cervical cancer from CIN.

The standardization of pediatric Tuina is beneficial to pediatric Tuina practitioners in a norm practices. The paper collects the content from teaching textbooks, TCM ancient books and database literature, and tries to develop the technical specifications of pediatric Tuina by four rounds Delphi surveys and expert consensus. This specification covers the manipulation of pediatric Tuina, the position of acupoints, the effects of acupoints and the diagnosis and treatment of pediatric Tuina, including indications, contraindications, cautious use, operation steps and methods.

[Objective] To explore the efficacy of disposable flexible ureteroscopic lithotripsy (FURL) with flexible vacuum-assisted ureteral access sheath (FV-UAS) in the treatment of 2-3 cm upper urinary tract stones, so as to provide reference for the treatment selection. [Methods] Clinical data of 178 patients with upper urinary tract stones who received FURL or minimally invasive percutaneous nephrolithotomy (MPCNL) at our hospital during Apr. 2022 and Oct. 2023 were retrospectively analyzed. The patients were divided into FV-UAS group (n=90, received FV-UAS combined with diaposable FURL treatment) and MPCNL group (n=88, received MPCNL). The general information, perioperative data, and postoperative stone-free rate (SFR) of the two groups were compared. [Results] All operations were successfully completed. The operation time was significantly longer in the FV-UAS group than in the MPCNL group [(66.5±6.7) min vs. (63.9±7.4) min, P=0.015]. However, the intraoperative hemoglobin reduction [(7.3±3.1)g/L vs.(11.4±5.9)g/L], postoperative hospital stay (P<0.001) [(2.2±0.7)d vs.(5.4±1.3)d], and visual analogue score (VAS) [(2.7±0.9)vs.(5.6±1.1)] were significantly lower in the FV-UAS group than in the MPCNL group (P<0.001). The incidence of persistent gross hematuria was significantly higher in the MPCNL group than in the FV-UAS group (12.5% vs. 3.3%, P=0.023). The FV-UAS group had a similar postoperative immediate (83.3%) and final SFR (95.6%) to those of the MPCNL group (89.8%, 96.6%, P>0.05). [Conclusion] The combination of FURL with FV-UAS for 2-3 cm upper urinary tract stones has a higher SFR and a lower complication rate.Patients experience endurable pain and fast recovery, which is worth promoting and applying in clinical practice.

[Objective] To compare the clinical efficacy and safety of flexible ureteroscope lithotripsy (FURL) combined with flexible vacuum-assisted urethral access sheath (FV-UAS) and traditional UAS in the treatment of 1-2 cm lower renal calyceal stones, so as to provide reference for clinical practice. [Methods] Clinical data of 157 patients with 1-2 cm lower renal calyceal stones treated with FURL during Mar.2021 and Oct.2023 were retrospectively analyzed, including 80 treated with traditional UAS, and 77 with FV-UAS.General and clinical information of the two groups were compared. [Results] The immediate stone-free rate (SFR) (84.4% vs.67.5%, P=0.013) and final SFR (88.3% vs. 75.0%, P=0.032) of the FV-UAS group were significantly higher than those of the traditional UAS group, with significant difference.The incidence of postoperative complications such as fever, renal colic, and perirenal hematoma was significantly higher in the traditional UAS group than in the FV-UAS group (15.0% vs.5.2%, P=0.042). After treatment with anti-infective and analgesic drugs, both groups were improved, and no severe sepsis or septic shock occurred after surgery.The hospitalization expenses of the FV-UAS group were significantly lower than those of the traditional UAS group [ (18 341±1519)yuan vs.(19 152±1826)yuan, P=0.003]. [Conclusion] Compared to the traditional UAS, the combination of FURL and FV-UAS for the 1-2 cm lower renal calyceal stones has a high SFR and low incidence of complications.Patients experience less pain, recover faster and spend less.It's a new treatment option for inferior calyceal calculi.
