Spontaneous regression of hepatocellular carcinoma: A mini-review

Spontaneous tumor regression is an extremely rare phenomenon in the oncology field. However, there are several case reports resulted in the regression of hepatocellular carcinoma(HCC) and the accumulation of clinical information and analyses of the mechanism can contribute to the development of a novel therapy. For this purpose, we have carefully reviewed 23 cases of spontaneously regressed HCC published in recent 5 years and our case. The information regarding the tumor size, tumor marker, treatments, etc., have been summarized. The mechanism of spontaneous regression has been discussed to date and presumed to be due to many factors, including hypoxia and immunological reactions. In this careful review of the 24 cases based on the clinical information, hypoxia, systemic inflammation, and both upon spontaneous regression were seen in 3, 8, and 4 cases, respectively amo ng t he 15 c as e s f or w hic h t he inf o r mat io n regarding the proposed mechanisms are available. Recent development of immunotherapeutic approaches in oncology shows promising results, therefore, accumulation of additional cases and analysis of mechanisms underlying the spontaneous regression of HCC are essential and could lead to the development of a new generation of immunotherapies including antibodies directed against immune reactions.

Clinicopathological Features of Non-familial Colorectal Cancer with High-frequency Microsatellite Instability

Objective To explore the clinicopathological features of non-familial colorectal cancer with high-frequency microsatellite instability (MSI-H). Methods One hundred and fifty patients with colorectal cancer who had no family history were enrolled in this study from June 2006 to June 2008. Five standard microsatellite loci including BAT25, BAT26, D2S123, D5S346, and D17S250 were amplified with immunofluorescent polymerase chain reaction. The patient information including age, sex, and tumor location was recorded. Pathological features including differentiation, mucinous differentiation, histological heterogeneity, and Crohn's-like reaction were observed under light microscope. The presence of tumor-infiltrating lymphocytes (TLs, CD4+ and CD8+) was detected by means of immunohistochemistry. A regression equation was obtained by stepwise logistic regression analysis to evaluate the relationship between MSI-H phenotype in colorectal cancer ands pathological features. Results MSI-H phenotype occurred in 13.33% of the 150 patients with non-familial colorectal cancer. Poor differentiation, histological heterogeneity, Crohn's-like reaction, and presence of TLs were found to be independent factors to identify MSI-H non-familial colorectal cancer. Logistic regression equation showed an overall sensitivity of 70.0%, specificity of 99.2%, and accuracy of 95.3% in identifying MSI-H non-familial colorectal cancer. Conclusion MSI-H non-familial colorectal cancer manifests specific pathological features, which may be relied upon for effective identification of that disease.

Aberrant methylation of the 3q25 tumor suppressor gene PTX3 in human esophageal squamous cell carcinoma

AIM:To identify the novel methylation-silenced gene pentraxin 3(PTX3) in esophageal squamous cell carcinoma(ESCC).METHODS:PTX3 mRNA expression was examined in six human ESCC cell lines,one human immortalized normal esophageal epithelial cell line,primary ESCC tumor tissue,and paired adjacent nontumor tissue using reverse transcription polymerase chain reaction(RTPCR).Semi-quantitative immunohistochemistry was used to examine cellular localisation and protein levels.Methylation specific PCR and bisulphite genomic sequencing were employed to investigate the methylation of the candidate gene.RESULTS:In the majority of ESCC cell lines,we found that PTX3 expression was down-regulated due to gene promoter hypermethylation,which was further confirmed by bisulphite genomic sequencing.Demethylation treatment with 5-aza-2'-deoxycytidine restored PTX3 mRNA expression in ESCC cell lines.Methylation was more common in tumor tissues(85%) than in adjacent nontumor tissues(25%)(P < 0.01).CONCLUSION:PTX3 is down-regulated through promoter hypermethylation in ESCC,and could potentially serve as a biomarker of ESCC.

Trust and Structural Response to Natural Disaster： Some Implications to Government Reform

The Philippine government is a representative democracy. It has three co-equal branches of government namely the executive, legislative, and judicial, operating on the principle of check and balance. Issues that had riddled top officials of government remained unresolved hitherto; and, the local government units had their own lingering issues. The government structure therefore did not seem to have the mechanism to correct itself. This paper argues that responses to, as well as the ensuing conditions of the survivors of natural disasters, are affected by how much trust the incumbents of relevant government structures have of each other and that actors outside of the government hierarchy can offer avenues for reform. Tropical Storm Washi that hit Cagayan de Oro City could be a case in point. It left thousands of people dead or missing, millions of dollars in damages, and thousands of internally displaced persons （IDPs）. The local government, tasked by the local government code to handle matters related to social welfare, did not seem to have performed as expected. In an apparent lack of trust, donor agencies preferred to course cash and relief items through conduits others than the local government. While the system remained unable to correct itself, the victims of the disaster continued to suffer. Civil society organizations and non-government organizations were trying to re-establish people’s trust in the system through legal measures, and hope that electoral reforms could be instituted.

Effect of Wuziyanzong pill on levels of sex hormones, and expressions of nuclear- associated antigen Ki-67 and androgen receptor in testes of young rats

OBJECTIVE: To evaluate the effects of Wuziyanzong pill on the levels of serum follicle stimulating hormone(FSH), luteinizing hormone(LH), testosterone(T) and the expressions of nuclear-associated antigen Ki67(Ki67), androgen receptor(AR) in testes of young rats.METHODS: Sixteen 20-day-old Wistar male rats were randomly divided into control and treatment group(n = 8). Rats in treatment group were administered Wuziyanzong pill by gavage; rats in control group administered the same volume of saline. After 10 days of treatment, the rats were killed, and then serum and testes were taken. The levels of FSH, LH and T were measured by radioimmunoassay(RIA). The histology of seminiferous tubule was observed by hematoxylin-eosin(HE) staining. The expression of Ki67 was detected by immunohistochemical assay(IHC). The m RNA level of Ki67, ARand CK-18 was detected with quantitative real-time polymerase chain reaction(Q-RT-PCR), the protein level of AR and CK-18 were tested by Western blot.RESULTS: Compared with control group, T level in treatment group increased significantly(P < 0.05).HE staining showed that both leydig cells and germ cells increased in treatment group. Expressions of Ki67 and AR became higher after treatment. There were no changes in CK-18 expression.CONCLUSION: Wuziyanzong pill can up-regulate AR level to promote germ cell proliferation and differentiation in young male rats.
