Huaier (Trametes robiniophila) has been widely used as an adjuvant drug for cancer treatment in China. The anti-cancer effect of Huaier extract has been confirmed in liver cancer, lung cancer, breast cancer, ovarian cancer, gastric cancer, and so on. The main mechanisms by which Huaier exerts an anti-neoplastic effect include inhibition of the growth and proliferation of cancer cells, induction of apoptosis of cancer cells, suppression of angiogenesis, inhibition of the invasion and migration of cancer cells, regulation of oncogenes and tumor suppressor genes expression, improving immunity, and reversal of drug resistance in cancer cells. In order to provide references for further study and clinical application on anti-tumor effect of Huaier, the latest research progress on anti-tumor effect of Huaier in recent years is summarized in this paper.

Objective To investigate the feasibility, safety and short-term efficacy of endoscopic implantation of 5-FU Slow-release Particles for advanced gastroenteric tumor. Methods During the endoscopy procedure,slow-releasing 5-FU agents were implanted densely into the tumors and infiltrated area. Forty-five to sixty pieces of agents ( each piece equivalent to 1.67 mg 5-FU)were injected, which containing an average dose of 100 mg 5-FU. Results A total of 13 advanced gastric cancer patients were enrolled into this study. Significant effects were observed in 3 patients and good effects in 8 patients, but 2 cases with no effects. The total effective rate was 84.62%. The endoscopy examination showed that the size of tumors reduced in various degree at 1 - 2months after the implantation. No hemorrhage or perforation was observed. Parameters of hepatorenal function and routine blood test were stable after implantation. Conclusion Endoscopic implantation of 5-FU Slow-release Particles can relieve the symptoms of patients and limit tumor growth in advanced gastroenteric tumor with no marrow and hepatorenal functional impair.

Objective To study the utilization of preoperative ultrasound-guided fine-needle aspiration(USFNA) for axillary lymphnode(ALN) metastasis in breast cancer and to evaluate the feasibility and accuracy of the technique. Methods Forty ALNs in 40 armpit negative palpation highly suspective breast cancer patients underwent USFNA. The cytopathological results were compared with the histopathological results of sentinel lymphnode(SLN) biopsy or axillary lymphnode dissection(ALND). The sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) and diagnostic accuracy of USFNA for the ALN metastasis were analysed. Results All the 40 patients were confirmed with breast cancer by pathology. Sensitivity of USFNA was 52. 2%, specificity was 100%, PPV was 100%,NPV was 60. 7% and diagnostic accuracy was 72. 5%. 12(30% ) patients with positive cytology proceeded to ALND, avoiding SLN biopsy. Conclusions USFNA is a minimally invasive, highly specified technique for prediction of breast cancer ALN metastasis before operation.

BACKGROUND:Tumor necrosis factor α, as a pathogenic factor, induces the inflammatory reaction mainlyvia the activation of the nuclear factor kappa B signaling pathway. Low density lipoprotein receptor-related protein 1 (LRP1) is involved in the regulation of the inflammatory reaction induced by cytokines.
OBJECTIVE:To study the effect of knockdown of LRP1 on tumor necrosis factor α-induced inflammatory reaction.
METHODS: Primary cultured rat chondrocytes were transfected with lentivirus-mediated RNA interference to knockdown LRP1 gene. Three days after lentivirus transfection, chondrocytes were pretreated with Bay 11-7082 (10 μmol/L) for 30 minutes prior to the addition of tumor necrosis factor α (30 μg/L) for 30 minutes. Signaling protein and mRNA expressions in chondrocytes were detected by western blot assay and real-time PCR analysis, respectively. Chondrocytes were pretreated with or not Bay 11-7082 (10 μmol/L) 30 minutes prior to the addition of tumor necrosis factor α (30 μg/L) for 12 hours after starvation in DMEM for overnight, and the culture medium was colected for ELISA determination of matrix metaloproteinase 13 level.
RESULTS AND CONCLUSION:Tumor necrosis factor α receptor 1 expression was upregulated in chondrocytes after lentivirus-induced knockdown of LRP1. Increased expression of inducible nitric oxide synthase and activation of the nuclear factor kappa B signaling pathway were found after the addition of tumor necrosis factor α in shLRP1 group. Moreover, increased level of matrix metaloproteinase 13 was determined by ELISA. Taken together, knockdown of LRP1 up-regulates the expression of tumor necrosis factor α-induced inducible nitric oxide synthase and matrix metaloproteinase 13 through the activation of the nuclear factor kappa B signaling pathway.

BACKGROUND:Emerging evidence demonstrates that low density lipoprotein receptor-related protein 1 (LRP1)isinvolved in lipid metabolism and regulation of inflammatory reaction.
OBJECTIVE:To explore the effectof lentivirus-induced knockdown of low density lipoprotein receptor-related protein 1 on cartilage damage and matrix metaloproteinase 13 in a rat model of osteoarthritis, so as to assess the role of low density lipoprotein receptor-related protein 1 in the pathogenesis of osteoarthritis.
METHODS:Sixty-fourSprague-Dawleyratswere included andramdomlydivided into four groups (n=16 for each): negative control group, no surgery; sham-surgery group, onlythearticular cavity of the knee was exposed; osteoarthritisplus shLRP1 group, rat osteoarthritis models were established by cutting anterior cruciate ligament and removing the medial meniscus partly folowed by an intra-articular injection of lentivirus-mediated siRNA at 2 days after surgery, once a week for 2 consecutive weeks; osteoarthritis group,an intra-articular injection of the negative control lentivirus was performed after surgery. Rats inthe four groups started running on theself-made electric treadmil from 5 days after modeling, 30 minutes per day,totaly 500 meters. Cartilage damage and matrix metaloproteinase 13 expression in cartilage tissues were determined at 2, 4, 6 weeks after surgery.
RESULTS AND CONCLUSION:Gross and pathological observations showed that lentivirus-induced knockdown of lowdensity lipoprotein receptor-related protein 1 aggravatedcartilage damage intherat model of osteoarthritis. At 6 weeks after surgery, Mankin’s scoreand matrix metaloproteinase 13 expression inthecartilage tissues in osteoarthritis plus shLRP1 groupweresignificantly increased compared with other three groups (P< 0.05). These findings indicate that a simulation model of osteoarthritis is developed by cutting anterior cruciate ligament and removing the medial meniscus partly combined with running onthe treadmil. Lentivirus-induced knockdown ofLRP1aggravates cartilage damage in a rat model of osteoarthritis

Objective To explore preliminary clinical results of a new anatomical shape allogeneic bone posterior lumbar fusion cage. Methods Follow-up patients used the allogeneic bone posterior lumbar fusion cage and use imaging methods and clinical score (VAS, ODI) to evaluate the patients′ clinical efficacy. Results 14 patients were followed up for 6 months or more , with an average follow-up time of 9.7 months , mean preoperative VAS 6.8 ± 1.1, ODI 32.7 ± 4.5. The mean preoperative disc height was (9.7 ± 2.0) mm and the average intervertebral height of 3 days post operation was (13.2 ± 1.7) mm. All patients got bony fusion in 6 months post operation, pain and function scores improved significantly compared with the pre-operation: VAS 2.4 ± 0.8 (P =0.000), ODI 9.8 ± 2.5 (P = 0.000), the average intervertebral height was (13.1 ± 1.7) mm (P = 0.000). The average was VAS 2.1 ± 0.1 (P = 0.000), average ODI was 8.9 ± 0.9 (P = 0.000) at last follow up. Average of intervertebral height was (13.0 ± 1.8) mm, no significant difference compared to three days after surgery (P=0.831). No serious complications and deep surgical site infection was observed. All implants were found no fragmentation, shift, cutting boards, and obviously sinking. Conclusion The anatomical shape allogeneic bone posterior lumbar fusion device is suitable for posterior lumbar interbody fusion , advantages of high fusion rate , satisfactory clinical results in the initial clinical trials , but its long-term efficacy requires further observation.
