Cardiac troponin as a prognosticator of mortality in patients with sepsis: A systematic review and meta-analysis.

BACKGROUND: The impact of cardiac troponin on the short-term and long-term prognosis of patients with sepsis remains uncertain. Therefore, we conducted a meta-analysis to investigate the role of cardiac troponin as a potential indicator for sepsis mortality. METHODS: We performed a comprehensive search for articles published before November 2022 using Google Scholar, PubMed, and Web of Science. Inclusion criteria for the studies were: (1) investigation of cardiac troponin, and (2) investigation of sepsis. Exclusion criteria included: (1) inability to obtain or calculate hazard ratio (HR) and 95% confidence interval (CI) for the relationship between cardiac troponin level and sepsis mortality, and (2) reviews, meta-analyses, and case reports. Analysis of HRs and 95% CIs for the association between cardiac troponin level and sepsis mortality was conducted using STATA 12.0 software. RESULTS: Our study included 24 prospective studies (comprising 20,457 sepsis patients) and 4 retrospective studies (comprising 1416 sepsis patients). Meta-analysis demonstrated that elevated cardiac troponin levels were significantly associated with increased sepsis mortality using a random effects model (HR = 1.57, 95% CI 1.41-1.75). Moreover, elevated cardiac troponin levels were also significantly associated with increased hospital mortality of sepsis (HR = 1.35, 95% CI 1.19-1.53) and long-term mortality of sepsis (HR = 1.96, 95% CI 1.51-2.55) using the random effects model. CONCLUSIONS: Overall, our finding revealed that elevated cardiac troponin for sepsis patients was a predictor of hospital and long-term mortality. Clinicians may treat septic patients with elevated cardiac troponin more cautious to avoid extra death. Moreover, large clinical studies are warranted to validate this association.

Clonorchis sinensis infection and co-infection with the hepatitis B virus are important factors associated with cholangiocarcinoma and hepatocellular carcinoma.

To evaluate the contributions of Clonorchis sinensis and hepatitis B virus to the development of cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC), C. sinensis and hepatitis B virus infections in 20 clinical liver cancer cases from a C. sinensis- and hepatitis B virus-epidemic region were detected. Eight cases of ICC, 11 cases of HCC and one mixed ICC and HCC case were verified by CT, pathological section and (or) observations during surgery. The C. sinensis infection was detected by stool microscopy and ELISA, and the worms and eggs found during surgery and in pathological sections also allowed for diagnoses. Hepatitis B virus infections were detected by ELISA. In the 20 cases, 18 patients were diagnosed with C. sinensis infections. Eight of the 20 patients were infected with the hepatitis B virus, and seven were co-infected with C. sinensis. In the eight ICC patients, seven were diagnosed with C. sinensis infection, and two had mixed infections with the hepatitis B virus. In the 11 HCC patients, 10 were diagnosed with C. sinensis, four had mixed infections with the hepatitis B virus, and only one HCC patient presented a single infection by the hepatitis B virus. These clinical observations revealed that C. sinensis infection and C. sinensis co-infection with the hepatitis B virus are important factors in ICC and HCC.

Yiqi Huayu Jiedu Decoction Inhibits the Invasion and Metastasis of Gastric Cancer Cells through TGF-ß/Smad Pathway.

Background. Yiqi Huayu Jiedu Decoction (YHJD) can obviously improve the quality of life of those patients with gastric cancer and prolong their survival. Methods. In vitro experiments, we observe YHJD's effect on the cells' proliferation by MTT assay. Cell adhesion assay, wound-healing assay, and Transwell invasion assay serve to detect its influence on cells' adhesion, migration, and invasion, respectively. Inhibitor (10 µM/L of SB431542) and activator (10 ng/mL of TGF-ß) of TGF-ß/Smad pathway were used to estimate whether YHJD's impact on the biological behavior of gastric cancer cells was related to TGF-ß/Smad pathway. In in vivo studies, YHJD was administered to the nude mice transplanted with gastric cancer to observe its effect on the tumor. Western blotting and immunohistochemical assay were used to test relevant cytokines of TGF-ß/Smad pathway and epithelial-mesenchymal transition (EMT) in MGC-803 cells and the tumor bearing nude mice. Results. YHJD inhibited proliferation, adhesion, migration, and invasion of MGC-803 gastric cancer cells in vitro. In in vivo studies, YHJD reduced the volume of the transplanted tumors. It also enhanced the expression of E-cadherin and decreased the levels of N-cadherin, TGF-ß, Snail, and Slug in both MGC-803 cells and the transplanted tumor by western blot assay. The immunohistochemical assay revealed that YHJD raised E-cadherin in the tumors of the mice; on the contrary, the expression of N-cadherin, Twist, vimentin, TGF-ßR I, p-Smad2, p-Smad3, Snail, and Slug reduced. Conclusion. YHJD can effectively inhibit the invasion and metastasis of gastric cancer cells. The mechanism may be related to TGF-ß/Smad pathway.

Cinnamaldehyde induces apoptosis and reverses epithelial-mesenchymal transition through inhibition of Wnt/ß-catenin pathway in non-small cell lung cancer.

Cinnamaldehyde, the main chemical component of the essential oil separated from the traditional herb Cinnamomum cassia, has been demonstrated to be an efficient cytotoxic agent against several human cancers. The present experiment showed that cinnamaldehyde dose-dependently depresses the proliferation of three types of NSCLC cells and induces cell apoptosis in vitro and in vivo. Moreover, cinnamaldehyde attenuated CoCl2-induced EMT and decreased matrix metalloprotease (MMP) family while the in vivo study showed the same trend. Mechanistically, cinnamaldehyde imitated the suppressive effect of XAV939 on cell motility and EMT which could be impaired by LiCl. Collectively, our research demonstrated for the first time that cinnamaldehyde is able to inhibit NSCLC cell growth by inducing apoptosis and reverse EMT through terminating Wnt/ß-catenin pathway, which might supply further insight into cinnamaldehyde-mediated anti-tumor effect against NSCLC for better prognosis.

Compound Wumei Powder Inhibits the Invasion and Metastasis of Gastric Cancer via Cox-2/PGE2-PI3K/AKT/GSK3ß/ß-Catenin Signaling Pathway.

To explore the role of CWP in invasion and migration of gastric cancer cells and its underlying molecular mechanism, we performed the experiment in SGC-7901 cells both in vitro and in vivo. In the cell experiment, we evaluated cell proliferation by MTT assay. The results showed that CWP can inhibit the growth of SGC-7901 cells. The influence on cell migration and invasion was detected by wound-healing and Transwell invasion assays. The results showed that the abilities of invasion and migration are restrained in CWP group. Western blot showed that CWP can decrease the expression of Cox-2 and inhibit the PI3K/AKT/GSK3ß/ß-catenin signaling pathway. In the animal experiment, we observed that CWP had an inhibitory effect on the growth of xenograft tumors of nude mice. IHC assay, ELISA, RT-PCR assay, and Western blot assay were used to test relevant cytokines of Cox-2/PGE2-PI3K/AKT/GSK3ß/ß-catenin pathway. The results showed that CWP can suppress relevant cytokines of Cox-2/PGE2-PI3K/AKT/GSK3ß/ß-catenin pathway. In conclusion, we suggest that CWP inhibits the invasion and metastasis of SGC-7901 cells via Cox-2/PGE2-PI3K/AKT/GSK3ß/ß-catenin signaling pathway.
