Background:Upon inhibition of STAT3 signaling pathway,cucurbitacin-I elicits anticancer effect in various malignancies. However,the anticancer effect and underlying mechanism of cucurbitacin-I in gastric cancer is still elusive. Aims:To explore the effect of low nanomolar cucurbitacin-I on cell proliferation,cell cycle and apoptosis in human gastric cancer cells and the underlying mechanism in vitro. Methods:Human gastric adenocarcinoma cell lines AGS and HGC-27 were treated with cucurbitacin-I at low nanomolar concentration. The anti-proliferative effect of cucurbitacin-I was detected by CCK-8 assay and colony formation assay. Flow cytometry was used to assess the cell cycle and apoptosis. Expressions of cell cycle-related proteins,as well as activation of related pathways such as caspase-3 / PARP apoptotic pathway,STAT3, GADD45α and JNK/ p38 MAPK signaling pathways were determined by Western blotting. Results:Cucurbitacin-I markedly inhibited the growth of gastric cancer cells at low nanomolar concentration by inducing G2 / M phase arrest and apoptosis via a STAT3-independent manner. Furthermore,it was revealed that the anticancer effect of cucurbitacin-I was associated with up-regulation of GADD45α,activation of JNK/ p38 MAPK signaling pathway and the subsequent apoptotic events. Conclusions:The present study provides new insights into the mechanism of anticancer effect of cucurbitacin-I, supporting cucurbitacin-I as an attractive therapeutic drug in gastric cancer.

Objective To explore the value of Toll-like receptor 2(TLR2) on the diagnosis of neonatal septicemia especially for the early diagnosis.Methods Twenty-two newborns with septicemia were divided into 2 groups according to the time of onset:early-onset group(n=12) and late-onset group(n=10).Another 14 non-infectious newborns were collected as control group.The TLR2 mRNA in peripheral blood was detected by real-time polymerase chain reaction,and mononuclear cells were isolated by the density gradient centrifuga-tion;the C reaction protein(CRP) was detected,and the co-relationship of the indexes was analyzed by Pearson correlation analysis.Results 1.The level of CRP in early-onset group were(157.89?32.96) ng?L-1,and(89.78?16.24) ng?L-1 in late-onset group,and there was significant difference between both groups(P=0.001);(6.91?1.20) ng?L-1 in control group,which was significantly lower than that in early-onset group and late-onset group(P=0.000,0.001).2.The expression of TLR2 mRNA in early-onset group and late-onset group was(57.38?10.72)?1012 copies?L-1and(32.74?4.65) ?1012 copies?L-1,which was significantly higher than that in control group[(4.12?0.68) ?1012 copies?L-1].3.CRP is positively correlated with TLR2 mRNA(C=0.972,P=0.000).Conclusions TLR2 expression is proven to be related to both the level of CRP and the stage of onset and may play a key role in the pathogenesis of neonatal septicemia.Detection for TLR2 may assist the earlier diagnose of atypical neonatal septicemia.

Abstract: Objective To analyze the application effect of rapid diagnostic techniques in Shaanxi from 2016 to 2020,and to provide basis for further optimizing the process of tuberculosis detection and formulating prevention and control strategies. Methods A total of 104 437 cases of tuberculosis patients registered in Shaanxi Province from 2016-2020 were exported from the Tuberculosis Information Management System (The subsystem of China Disease Prevention and Control Information System) according to first management unit, and the laboratory test results of sputum smear, sputum culture and molecular tests were collected to statistically analyzed the positive rate of etiology, sputum smear, sputum culture, molecular biology testing rate, and indicators of positive testing rate of tuberculosis patients. Results From 2016 to 2020, the etiology�positive rate of tuberculosis in Shaanxi province were 13.49% (2 664/19 754), 22.68% (5 081/22 401), 35.99% (8 232/22 876), 48.14% (10 438 / 21 682), 52.65% (9 332 / 17 724), respectively, with an increasing trend (χ2 trend=9 473.12, P<0.001) year by year; the proportion of molecular tests positive only in etiology-positive pulmonary tuberculosis (PTB) were 0 (0/2 664), 0.16% (8/5 081), 15.44% (1 271/8 232), 27.58% (2 879/10 438), 31.52% (2 941/9 332), respectively, with an increasing trend year by year (χ2 trend=2 971.44, P<0.001); the molecular test rates of the 5 years were 0.01% (2 / 19 754), 0.38%(85 / 22 401), 21.11% (4 828/22 876), 52.42%(11 365/21 682), 55.18%(9 780/17 724), respectively, with an increasing trend year by year (χ2 trend = 28 269.23, P<0.001). The rate of molecular test in sputum smear-negative was 22.72%(17 976 / 79 130). The proportion of patients with only molecular test-positive was 33.43% (4 032/12 062) in municipal designated hospitals, and 11.99%(2 279/ 19 014) in county-level designated hospitals, the difference was statistically significant (χ2 =2 096.46, P<0.001). Conclusions The rate of molecular biology testing in Shaanxi Province from 2016 to 2020 showed a year-on-year increase. Through the application of rapid molecular tests, the etiology-positive rates of tuberculosis have been increased significantly,but the current molecular test detection rate is not high compared with other provinces, especially in county-level designated hospitals and smear-negative patients, so we should make a big promotion in application of rapid molecular technique.
