1.Treatment of hepatocellular carcinoma with portal vein tumor thrombus
Journal of International Oncology 2012;39(3):225-227
Hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) is one of the difficult points of liver cancer treatment.At present,there are various clinical treatments of HCC with PVTT which have great significance to lengthen the survival time of patients with liver cancer and improve the quality of life.Surgical therapy and interventional treatment play important roles in the treatments of HCC with PVTT.
2.Molecular biomarkers related prognosis in hepatocellular carcinoma
Journal of International Oncology 2015;(5):395-398
The occurence and progress of hepatocellular carcinoma(HCC)is a complex network inter-action process connected by multiple signaling pathways involving genes,cells and various active molecules. The effects and functions of biological molecular markers also vary among different pathways. Moreover,wheth-er the molecular markers have prediction effects for the prognosis of HCC remains unclear,and studies investing this issue are still insufficient. The current studies reveal that molecular markers involves in multiple pathways including gene expression,gene regulation,cell cycle regulation,cancer stem cell proliferation and differentia-tion. These processes are intimately associated with the occurrence and prognosis of HCC. The relevant gene or molecular that may indicate the prognosis of HCC includes p53 gene,long non-coding RNA,cell cycle regula-tors,liver cancer stem cell surface-associated molecules,etc.

·AIM:To report a case of entry of antibiotic ointment into the anterior chamber following sutureless clear corneal incisions phacoemulsification.·METHODS:A 62-year-old man had uneventful phaco-emulsification with clear corneal incisions with intraocular lens(IOL) implantation. Postoperative medication included antibiotic/steroid ointment; the eye was firmly patched at the end of the procedure. On the first postoperative day, the patient was seen an oily droplet floating in the anterior chamber. Immediate surgical removal of the ointment without IOL exchange was performed.·RESULTS:During follow-up for six months after irrigation/aspiration of the anterior chamber and removal of the oily droplet, visual acuity and intraocular pressure (IOP) were unchanged and anterior segment was formed and quiet.·CONCLUSION:Ophthalmic ointment may ingress into the anterior chamber through unstable clear corneal incisions. The case highlights the importance of appropriate wound construction and integrity, as well as the risk of tight eye patching following placement of ointment.

Objective To explore the methods of extraction, isolation, purification, and biological activities of ray cartilage glycosaminoglycans (RCG). Methods RCG was purified by guanidine hydrochlorid extraction, acetone fractional precipitation, ultrafiltration, and Sephadex column chromatography. The purity and molecular mass of RCG were measured by means of HPLC. The model of mouse with Lewis lung carcinoma was made, the experimental mice were randomly divided into normal saline group, RCG (500, 250, and 125 mg/kg) groups, and CTX (60 mg/kg) group. Tumor growth states of mice were observed, tumor growth curve was described, inhibitory rates of primary tumor and number of lung metastasis focus were measured; microvessel density (MVD) was quantitated by immunohistochemistry using monoclonal antibodies of CD31; the expression of vascular endothelial growth factor (VEGF) mRNA was determined with RT-PCR. Results Using HPLC, a single glycosaminoglycans with molecular mass 9.7?104 was collected and its purity exceeded ninty-nine percent. Tumor growth curves in RCG groups were smooth compared with saline group. There were significant differences of inhibitory rates of primary tumor, number of lung metastasis focus and MVD between RCG groups and saline group. VEGF mRNA expression levels in RCG groups were reduced significantly compared with saline group. Conclusion RCG could effectively inhibit the growth and metastasis of primary Lewis lung carcinoma in C57BL/6 mouse and angiogenesis.

Objective To analyze the allele frequencies of 5 short tandem repeat(STR)loci(D12S313,D12S304,D12S1640,D12S1708 and D12S1583)on chromosome 12 among Kashin-Beck disease(KBD)patients and the control population living in the area suffered from KBD.Methods Fifty KBD patient8 and 50 non-KBD patients were chosen in endemic afea of Shaanxi Province,5 STR loci on chromosome 12 were genotyped by the technology of polymerase chain reacfion(PCR)and capillary electmphoresis.The pelymorphisms of STR in these popIllations were analyzed.The allele and genotype frequencies of each STR in the corresponding groups were caleulated and compared. Results In KBD group,the 5 STR loci had 8,6,7,5 and 11 types ofalleles and 17,11,15,8 and 28 genotypes, respectively;while in the control group,the number of aUele types of 5 STR loci were 6,8,6,4 and 10,the number of genotype of those loci were 13,21,14,8 and 23,respectively The allele frequence of D12S304 locus was statiBtically significant between KBD patients and controls(P<0.05),especially for the 319 bp allele(P<0.006 25). Conclusion There is an association between D12S304 locus and KBD.The 319 bp allele might play the key role.

Objective To explore the effects of citicoline injection into Zusanli point (ST36) on learning and memory function of rats after traumatic brain injury (TBI). Methods The model was induced with the improved Feeney method. The rats were randomly divided into 5 groups: sham-operation group, control group, acupuncture point saline injection group, intraperitoneal drug injection group and acupuncture point drug injection group with 8 rats in each group. The rats in the acupuncture point drug or saline injection group were treated with acupuncture injection of citicoline or saline daily. The rats in the intraperitoneal drug injection group and control group were treated with intraperitoneal injection of citicoline or saline daily. The treatment continued for 14 d. The learning and memory function was evaluated with the Morris water maze test and passive avoidance test. Results Acupuncture point injection of citicoline can significantly shorten the escape latent period of TBI rats in Morris water tests and extend the latent period of learning and memory of TBI rats (P<0.05). Conclusion Acupuncture point injection is effective on the recovery of learning and memory function of rats after TBI.

Glioma is one of the most refractory tumors affecting the central nervous system. As a new technique, cryoablation has been considered for the treatment of glioma. Considering previous studies, we summarized the mechanism of cryoablation to treat glioma based on pathology and molecular biology perspectives. We also analyzed the indications, effects, and problems of cryoablation in clinical practice. Furthermore, we proposed that this technique may be used in future trends and applications. The mechanism of eradicating tumor cells by cryoablation involves the following:(1) using an ultralow temperature to induce necrosis and apoptosis;(2) changing the local microcirculation of tumors;and (3) adjusting anti-tumor immunity. As an alternative surgical treatment, cryoablation could improve the therapeutic effects by real-time medical imaging. Cryoablation combined with chemotherapy, radiotherapy, immunotherapy, and other methods could provide a more effective treatment for gliomas. Therefore, cryotherapy could be a possible treatment for glioma and become a sustained research field.
