RESUMO

Campanumoea javanica Bl. (CJ) traditionally used in Southwestern China, is now widely consumed as a health food across the nation. Due to its similar efficacy to Codonopsis Radix (CR) and their shared botanical family, CJ is often used as a substitute for CR. According to the Chinese Pharmacopoeia, Codonopsis pilosula var. modesta (Nannf.) L.T. Shen (CPM), Codonopsis pilosula (Franch.) Nannf. (CP), and Codonopsis tangshen Oliv. (CT) are the primary sources of CR. However, details on the differences in composition, effectiveness, and compositional between CJ and CR are still limited. Besides, there is little evidence to support the application of CJ as a drug. In this study, we employed widely targeted metabolomics, network pharmacology analysis, and molecular docking to explore the disparities in metabolite profiles between CJ and CR and to predict the pharmacological mechanisms of the dominant differential metabolites of CJ and their potential medicinal applications. The widely targeted metabolomics results indicated that 1,076, 1,102, 1,102, and 1,093 compounds, most phenolic acids, lipids, amino acids, and flavonoids, were characterized in CJ, CPM, CP, and CT, respectively. There were an average of 1061 shared compounds in CJ and CRs, with 95.07% similarity in metabolic profiles. Most of the metabolites in CJ were previously unreported. Twelve of the seventeen dominant metabolites found in CJ were directly associated with treating cancer and lactation, similar to the traditional medicinal efficacy. The molecular docking results showed that the dominant metabolites of CJ had good docking activity with the core targets PIK3R1, PIK3CA, ESR1, HSP90AA1, EGFR, and AKT1. This study provides a scientific basis for understanding the similarities and differences between CJ and CR at the metabolome level, offering a theoretical foundation for developing innovative medications from CJ. Additionally, it significantly enhances the metabolite databases for both CJ and CR.

RESUMO

Treatment of recurrent and metastatic Epstein-Barr virus-associated gastric carcinoma (EBVaGC) remains a challenge, particularly in developing countries, due to lack of efficient screening programs. Latent membrane protein 2A (LMP2A) has been reported to serve an important function in the development of EBVaGC. In previous years dihydroartemisinin (DHA), traditionally used as an anti-malarial agent, has been demonstrated to inhibit tumor growth with low toxicity to normal cells. In the present study, the anti-tumor effect of DHA in EBVaGC was investigated. The MTT assay was used to compare the viability of untreated and DHA-treated EBVaGC GT-38 cells. Flow cytometry was applied to determine the percentage of GT-38 cells at each stage of the cell cycle. Reverse transcription-polymerase chain reaction and western blotting were used to determine the expression of the LMP2A gene. The effect of DHA treatment in vivo was evaluated in nude mice bearing GT-38 tumors. The results of the present study revealed that DHA-treated cells exhibited a time- and dose-dependent inhibition of viability. DHA significantly increased the apoptotic rate of GT-38 cells following treatment with 20 µg/ml DHA for 48 h. DHA-treated GT-38 cells were blocked in the G0/G1 phase, resulting in an accumulation of G0/G1 phase cells and a significant decrease of G2/M phase cells. In vivo, the results of the present study revealed that DHA significantly inhibited the growth of GT-38 cell-transplanted tumors. The mRNA and protein levels of LMP2A were significantly downregulated in the DHA-treated group compared with the control group. The present data indicated that DHA inhibited cell growth and induced cell apoptosis of the EBVaGC GT-38 cell line via downregulation of LMP2A. DHA may therefore be a potential therapeutic candidate for the treatment of EBVaGC.

RESUMO

Preoperative aspartate aminotransferase-to-platelet ratio index (APRI) has been identified as a biochemical marker for histological fibrogenesis and fibrosis in cirrhosis and prognosis of hepatocellular carcinoma (HCC). Whether preoperative APRI can predict postoperative short-term outcomes has not been studied. The purpose of this study was to investigate the ability of preoperative APRI to predict short-term outcomes following liver resection for HCC. APRI was evaluated in 360 patients undergoing liver resection for HCC. The receiver operating characteristic curve analysis was conducted to determine the cutoff value of the APRI in predicting postoperative morbidity. Univariate and multivariate analysis was performed to identify the risk factors for postoperative outcomes. The correlation of the preoperative APRI value with clinicopathological parameters was also examined. We found that the optimal cutoff value of the APRI was set at 9.5 for postoperative complications. APRI was an independent risk factor for overall complications by univariate and multivariate analyses. HCC patients with elevated APRI (>9.5) had a worse liver function and significantly higher postoperative complication rate. In conclusion, preoperative APRI is a useful biochemical marker to predict postoperative outcomes in HCC patients.

RESUMO

Hirschsprung's disease (HD) is a common congenital gastrointestinal malformation, characterized by the lack of ganglion cells from the distal rectum to the proximal bowel, but the pathogenesis is not well understood. This paper evaluates the effects of autophagy in HD. Using electron microscopy, the autophagosomes were detected in three segments: narrow segment (NS), transitional segment (TS), and dilated segment (DS). Typical autophagosome structures are found in the Auerbach plexus of both NS and TS. Real-time PCR results showed that Beclin1 (NS vs. TS, P<0.01) and LC3 (NS vs. TS, P<0.05) mRNA were the highest in the NS, but p75 (NS vs. TS, P<0.01) was the highest in the DS. Correlation analysis results showed a positive correlation between Beclin1 and LC3 mRNA levels (R=0.736, P=0.000), whereas inverse correlations were found between p75 and Beclin1/LC3 mRNA levels (p75 vs. Beclin1: R=-0.714, P=0.000; p75 vs. LC3: R=-0.619, P=0.000). Immunohistochemistry analyses indicated a consistent result with mRNA levels, by increased Beclin1-positive and LC3-positive neurons, but reduced p75-positive neurons in the Auerbach plexus of TS compared with DS. These findings indicated that autophagy exists in the bowel of patients with HD. On the basis of the detection of the highest expression of the autophagy genes in NS, autophagy may additionally cause the lack of neurons.

RESUMO

PURPOSE: The present study aimed to evaluate laparoscopic appendectomy (LA) in comparison with conventional open appendectomy (OA) in children, with special emphasis on the extent of surgical trauma after LA and OA, and to assess whether LA had any clear advantages compared with conventional OA. METHODS: A total of 160 patients with a median age of 7.9 years (range 3-15 years) were studied. Sixty-nine of them underwent LA, and the remaining 91 underwent OA. Serum interleukin (IL) 6 and C-reactive protein (CRP) levels which are thought to play a pivotal role in the pathogenesis of surgical trauma and can also be used to monitor the magnitude of surgical trauma were measured using an enzyme-linked immunosorbent assay before surgery and 12 hours after surgery. In addition, we compared operating time, hospital stay, incidence of wound infection, and incidence of intra-abdominal infection. RESULTS: The operative time of normal and suppurative appendix in the laparoscopic group was significantly shorter than that in the open group, respectively, but the operative time of gangrenous appendix was not different between the laparoscopic group and open group. The hospital stay in the laparoscopic group was also significantly shorter than that in the open group. Postoperatively, 1 patient had port-site infection in the laparoscopic group, whereas 10 had wound infection in the open group; this difference was highly significant (chi2 = 4.19, P < .05). Three patients in the open group and 2 patients in the laparoscopic group had intra-abdominal infection, and the difference had no statistically significant difference (chi2 = 0.10, P < .05). Preoperative IL-6 levels were not different between the 2 groups, but the rise (preoperative vs postoperative) of IL-6 in the laparoscopic group was remarkably less than that in the open group. Similar results were obtained for CRP; serum CRP levels in the basal state were not different between the 2 groups, but the rise (preoperative vs postoperative) of CRP in the laparoscopic group was also substantially less compared with that in the open group. CONCLUSIONS: LA for children was as safe and effective as the open procedure and had significant advantages over OA because of less operating time, less postoperative complications, less surgical trauma, and more rapid postoperative recovery.
