Objective To explore the clinical characteristics, surgical treatment and related factors of traumatic implantation cyst of the iris. Design Retrospective cases series. Participants Thirty-six cases of traumatic implantation cyst of the iris. Methods Thir- ty-six cases of traumatic implantation cyst of the iris were reviewed. Main Outcome Measures Age, surgical history, history of disease, surgical method of patients. Results All cases of traumatic implantation cyst of the iris were secondary to perforating injury. 10 cases had been undertaken cataract surgery. The histories of disease in 6 months~1 year and 1 year~10 years were 30.56% respectively. Sur- gical exicision was taken in all cases. There were 2 recurrence cases. Conclusion Traumatic implantation cyst of the iris is almost see- ondary to perforating injury. Surgical excision is an effective strategy to treat this disease.

OBJECTIVETo explore the molecular mechanism by which Biejiajian pills inhibit hepatocellular carcinoma in a nude mouse model bearing HepG2 cell xenograft.
METHODSThe inhibitory effect of Biejiajian pills on the growth of HepG2 cell xenograft in nude mice was observed. Immunohistochemical method was used to examine proliferating cell nuclear antigen (PCNA) expression in HepG2 cell xenograft, and TUNEL method was employed to detect the cell apoptosis; the expression levels of β-catenin and Tbx3 were measured by Western blotting.
RESULTSBiejiajian pills significantly suppressed the growth of HepG2 cell xenograft in nude mice. The tumor-bearing mice treated with a high and a moderate dose of Biejiajian pills showed significantly increased apoptosis rate of the tumor cells [(22.9±1.220)% and (14.7±0.50)%, respectively] compared with the control group [(5.5±0.90)%, P<0.05]. Treatment with Biejiajian pills significantly decreased the expressions of PNCA, β-catenin, and Tbx3 in the cell xenograft (P<0.05).
CONCLUSIONSBiejiajian pills can inhibit the growth of HepG2 cell xenograft in nude mice and promote tumor cell apoptosis possibly by inhibiting PNCA expression and the Wnt/β-catenin signaling pathway.

Objective To explore the association between tumor necrosis factor receptor associated factor 6 (TRAF6) polymorphisms and the susceptibility to sepsis. Method Haplotype tagging single nucleotide polymorphisms (htSNPs) were selected from the HapMap database. The htSNPs were genotyped in 255 patients with sepsis and 260 control subjects by the Beckman SNP stream genotyping platform. The association with susceptibility to and severity of sepsis were estimated by logistic regression with adjustment for age, sex, smoking, drinking,chronic diseases status, APACHE Ⅱ score and critical illness. Results Of 13 TRAF6 ANPs, 7 were tagged by htSNPs. Of them, 5 htSNPs (rs5030496, rs5030411, rs5030416, rs5030445 and rs3740961) were used for final genotyping analysis. Genotype frequencies of those htSNPs were conformed to the Hardy-Weinberg law in both patients and controls. There were no significant association found between the 5 htSNPs and susceptibility to sepsis.Also, there was no significant association between the TRAF6 polymorphisms and the septic shock, death from sepsis as well as organ dysfunction. Conclusions The TRAF6 gene polymorphisms might not play a major role in severity of sepsis.

OBJECTIVETo investigate the reliability of magnetic-activated cell sorting (MACS) combined with multiplex ligation-dependent probe amplification (MLPA) in the detection of the molecular cytogenetic abnormalities in multiple myeloma.
METHODSThe bone marrow cells were collected from 29 patients with multiple myeloma. The immuno magnetically sorted and unsorted cells were detected for TP53 and RB1 expressions using MLPA probes and the results were compared with fluorescent in situ hybridization (FISH).
RESULTSThe detection success rate was 100% for MLPA, which yielded results with an concordance rate of 99.1% with the FISH results. The positivity rates of MLPA and FISH were both increased after immunomagnetic sorting of the bone marrow cells.
CONCLUSIONMLPA can well suit the clinical needs for detecting molecular cytogenetic abnormalities in multiple myeloma, and the samples should be immuno magnetically sorted before the assay.

BACKGROUNDHepatoblastoma (HB) is a rare childhood tumor. We investigated the effect of intraoperative management of the intrahepatic major vessels in children with HB.
METHODSBetween April 2005 and August 2012, surgical resection was performed on 50 children with hepatoblastoma. These children were divided into a vessel-ligation group (n = 20) and a vessel-repair group (n = 30). In the vessel-ligation group, the intrahepatic major vessels were ligated and removed together with the tumor and the affected liver lobe/liver parenchyma. In the vessel-repair group, the affected intrahepatic major vessels were dissected and preserved as much as possible and the normal liver lobe/liver parenchyma and blood supply from these vessels were also preserved. The outcomes were analyzed by postoperative follow-up.
RESULTSIn the vessel-ligation group, two patients gave up surgery, six patients underwent palliative resection, and 12 patients underwent en bloc resection; four patients died of liver failure and eight patients fully recovered and were discharged. In the vessel-repair group, all 30 patients underwent en bloc resection and were discharged after satisfactory healing. After a follow-up time of 5 - 36 months (median: 20 months), two patient in the vessel-ligation group survived and 22 patients in the vessel-repair group survived.
CONCLUSIONSPatients with HB can be successfully treated by tumor resection with vascular repair. This method prevents postoperative liver failure, ensures patient safety during the perioperative period, and allows for early chemotherapy.

In the present study, a newly synthesized benzofuran lignan 4-formyl-2-(4-hydroxy-3methoxyphenyl)-5-(2-methoxycarbonyethyl)-7-methoxy-benzo [b] furan (ERJT-12) was tested for its antiproliferative activity on human tumor cells. The related mechanisms were also investigated. In vitro growth inhibitory effects of ERJT-12 on various cancer cell lines were determined by MTT assay. Cell cycle distribution and apoptosis were detected by flow cytometry. The integrity of DNA was assessed by agarose gel electrophoresis. Activation of Caspase-3/7 and Caspase-6 was measured by colorimetric assay. The expressions of cell cycle proteins cell divide cycle 25c (Cdc25c), cyclin dependent kinase 1 (CDK1), CyclinB1 and apoptosis-related proteins Bax and Bcl-2 were detected by Western blotting. MTT assay showed that ERJT-12 inhibited the proliferation of several cancer cell lines including multidrug resistant cells. MCF-7 cells were markedly arrested at gap2/mitosis (G2/M) phase after treatment with ERJT-12 and progressed into apoptosis. The increased activities of Caspase-3/7 and Caspase-6 in MCF-7 cells were observed. The expression of CyclinB1 was down-regulated. The activities of Cdc25c and CDK1 protein were suppressed and Bcl-2 protein was phosphorylated. ERJT-12 displays potent antiproliferative activity towards cancer cells through suppressing cell cycle proteins, arresting cell cycle at G2/M phase and inducing apoptosis. It might be a novel candidate for cancer therapy.

BACKGROUND: The tumor necrosis factor recepter associated factor (TRAF) 6 is an important intracellular adapter protein that plays a pivotal role in activating multiple inflammatory and immune related processes induced by cytokines. TRAF6 represents a strong candidate susceptibility factor for sepsis. We investigated whether polymorphisms at the TRAF6 gene are associated with the susceptibility to and severity of sepsis. METHODS: A hospital-based case-control study was conducted with 255 patients with sepsis and 260 controls who were recruited from Zhengzhou, China. Haplotype tagging single nucleotide polymorphisms (htSNPs) were selected from the HapMap database and genotyped using the SNPstream genotyping platform. The associations with the susceptibility and disease severity of sepsis were estimated by logistic regression, and adjusted for age, sex, smoking, drinking, chronic diseases status, APACHEII score and critical illness status. RESULTS: A total of 13 TRAF6 SNPs were tagged by 7 htSNPs. Five htSNPs (rs5030490, rs5030411, rs5030416, rs5030445 and rs3740961) were genotyped in the case control study. Genotype frequencies of the htSNPs were conformed to the Hardy-Weinberg equilibrium in both patients and controls. No significant association was found between the 5 htSNPs and the susceptibility to and severity of sepsis. Compared with the main haplotype -11120A/-10688T/-9423A/805G/12967G, no certain haplotype was associated with the significantly susceptibility to or severity of sepsis. CONCLUSION: TRAF6 gene polymorphisms might not play a major role in mediating the susceptibility to and severity of sepsis in the Chinese population. A larger population-based case-control study is warranted.

OBJECTIVETo determine whether -Taq I T/C and -Fok I C/T polymorphisms of vitamin D receptor (VDR) gene are associated with the familial aggregation of hepatitis B virus (HBV) infection.
METHODSBased on a population-based case-control family design, 288 family members from 27 case families and 230 family members from 27 control families were recruited. VDR gene polymorphisms were analyzed. VDR-Taq I T/C and VDR-Fok I C/T polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism.
RESULTSThe frequency of VDR-Taq I TT genotype in the case families was significantly higher than that in the control families (P < 0.05) , however, the frequency of VDR-Fok I CC genotype in the case families was significantly higher than that in the control families (P < 0.05). The frequency of family members carriying Taq I T-Fok I C haplotype in the case families was significantly higher than that in the control families (OR = 1.67, P < 0.05), however, the frequency of family members carrying Taq I C-Fok I T haplotype in the case families was significantly lower than that in the control families (OR = 0. 24, P < 0.05). The similar results were found in the familial biological kinship relatives with any HBV-infected makers.
CONCLUSIONVDR-Taq I and -Fok I gene polymorphisms are likely to play a substantial role in HBsAg familial aggregation.

Intrauterine infection is an important cause of some birth defects worldwide. The most common pathogens include rubella virus, cytomegaloviurs, ureaplasma urealyticum, toxoplasma, etc. General information about these pathogens in epidemiology, consequence of birth defects, and the possible mechanisms in the progress of birth defects, and the interventions to prevent or treat these pathogens' infections are described. The infections caused by rubella virus, cytomegaloviurs, ureaplasma urealyticum, toxoplasma, etc. are common, yet they are proved to be fatal during the pregnant period, especially during the first trimester. These infections may cause sterility, abortion, stillbirth, low birth weight, and affect multiple organs that may induce loss of hearing and vision, even fetal deformity and the long-term effects. These pathogens' infections may influence the microenvironment of placenta, including levels of enzymes and cytokines, and affect chondriosome that may induce the progress of birth defect. Early diagnosis of infections during pregnancy should be strengthened. There are still many things to be settled, such as the molecular mechanisms of birth defects, the effective vaccines to certain pathogens. Birth defect researches in terms of etiology and the development of applicable and sensitive pathogen detection technology and methods are imperative.
