Effect of Qufu Shengji ointment(QFSJO) on promoting the healing of infectious wounds / 中国骨伤

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(<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.

Intraperitoneal chemotherapy with mitomycin C bound to activated carbon nanoparticles for nude mice bearing human gastric carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>MMC-ACNP gives a good promise of clinical use due to its advantages such as high selectivity and low toxicity.</p>
