ABSTRACT
OBJECTIVE: To explore the clinical effect of Qufu Shengji ointment(QFSJO) in promoting the wound healing after trauma. METHODS: From January 2014 to June 2018, 60 patients with soft tissue injury, skin defect and wound infection caused by violent trauma were admitted, including 32 males and 28 females, aged from 18 to 65 years, with an average age of 41.3 years. Among them, 30 patients were treated with QFSJO (QFSJO group) and 30 patients were treated with normal saline iodophor (control group). The reduction rate of wound area, the days of decayed flesh, the time of new epithelium and the recovery rate of 28 days after dressing change were compared between the two groups. RESULTS: In the QFSJO group, after using large dose of QFSJO, the pus of the wound increased, the granulation grew, and the new epithelium appeared on the edge of the wound, showing a rapid healing phenomenon. The wound healing rate of QFSJO group was higher than that of the control group at all time points, and the time of decaying flesh and new epithelium appeared in QFSJO group was earlier than that of the control group. The recovery rate of QFSJO group was significantly higher than that of the control group(P<0.05). All the patients were followed up, and the duration ranged form 6 to 12 months, with an average of 9.4 months. The exposed areas of bone and teadon were covered well. The vital signs of the two groups were stable and no adverse reactions occurred. CONCLUSIONS: QFSJO can promote the growth of granulation tissue, promote the production of new skin, and accelerate the healing of infectious wound after trauma.

In the present study, the gene expression of ATP-binding cassette protein E1 (ABCE1) in the EC109 human esophageal cancer cell line was silenced using electroporation to examine the effect if the ABCE1 gene on the growth migration and cell cycle of cancer cells. The small interference (si)RNA sequence of ABCE1 was designed and synthesized to transfect the EC109 cells by electroporation. The mRNA and protein expression levels of ABCE1 were then detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot analysis. The analysis of the cell cycle and apoptosis was performed using flow cytometry. The effect of silencing the ABCE1 gene on the proliferation, migration and invasive ability of the EC109 human esophageal cancer cells were assessed using a Cell counting kit-8 (CCK-8) and with proliferation, wound-healing and cell invasion assays. The mRNA and protein expression levels of ABCE1 were significantly lower in the experimental group compared with the control group (P<0.05). The apoptotic rate of the experimental group was markedly higher than the control group and blank group (P<0.01). The CCK-8 proliferation assay revealed that, compared with the control and blank groups, the proliferation of the EC109 cells in the experimental group was significantly inhibited (P<0.05). The wound healing assay revealed that the migration capacity of the cells in the experimental group was significantly decreased (P<0.05). The Transwell chamber assay demonstrated that the invasive ability of the EC109 cells in the experimental group was significantly decreased (P<0.01). These results revealed that ABCE1 is closely associated with cell proliferation, invasion and migration in esophageal cancer and silencing the ABCE1 gene by electroporation can significantly reduce the proliferation, invasion and migration capacity of EC109 cells in vitro.

OBJECTIVE: To prepare a new dosage formulation of activated carbon nanoparticles adsorbing mitomycin C (MMC-ACNP) and evaluate the beneficial effects of intraperitoneally applied MMC-ACNP as a drug delivery system for lymphatic targeting in preventing metastasis and recurrence of gastric cancer. METHODS: MMC-ACNP was prepared. Acute toxicity after its intraperitoneal administration was evaluated. An experiment on nude mice model with transplanted human gastric cancer in 6 groups was completed to assess the effects of drugs on intra-abdominal carcinomatosis. RESULTS: The LD50 of MMC-ACNP was 46.80 mg/kg (in terms of MMC) while that of MMC aqueous solution was 9.33 mg/kg. The toxicity of MMC-ACNP was much less than that of the solution form. MMC-ACNP was superior to MMC aqueous solution in controlling carcinomatosis and tumor growth by intraperitoneal administration. Despite the high dose of MMC, leukopenia and thrombocytopenia were not observed in the MMC-ACNP treated group. Fine activated carbon particles adsorbing MMC entered the nuclei of tumor cells, so that the effects of the anticancer drug were reinforced. CONCLUSION: MMC-ACNP gives a good promise of clinical use due to its advantages such as high selectivity and low toxicity.
