The article focuses on diagnostic criteria and diagnostic accuracy of the various imaging methods by lymph node metastasis in esophageal carcinoma at present, and compares accuracy of the various imaging methods. In general, the diagnostic accuracy of CT is lower, the diagnostic accuracy of uhrasmall superparamagnetic iron oxide-enhanced MR imaging is higher. Each imaging method has the lower accuracy for the diagnosis of smaller lymph node metastasis. Diagnostic accuracy of endoscopic ultrasonography is higher in the diagnosis of mediastinal lymph node metastasis. Sensitivity of PET/CT is higher for the diagnosis of distant lymph node metastasis.

Objective: To investigate the mechanism of tea polyphenol in inhibiting microsatellite instability (MSI) of colorectal cancer. Methods: Using LoVo cells and SW480 cells treated with aqueous solution of tea polyphenol, cell proliferation was detected by methyl thiazolyl tetrazolium (MTT) method, changes in microsatellite sequences were detected by genescan method and changes in gene expression of LoVo cells were detected by illumina expression arrays and quantitative real-time polymerase chain reaction (PCR). Results: The proliferation inhibition rates of LoVo and SW480 cells treated with tea polyphenol increased with the increasing of drug concentration and showed an increasing tendency with time. The proliferation inhibition rate of LoVo cells with tea polyphenol was higher than that of SW480 cells, and there was a significant difference in the proliferation inhibition rates at 24 h, 72 h and one week. The microsatellite sequence of LoVo cells treated with tea polyphenol remained stable. The gene expression arrays and quantitative real-time PCR suggested that tea polyphenol inhibited the gene expressions of MT2A, MAFA, HES1 and JAG1 nearly two-fold over controls. It was also found that tea polyphenol inhibited the BAX and p38 genes with a more than two-fold difference but did not significantly inhibit the nuclear factor-κB pathway. Conclusion: Tea polyphenol significantly inhibited the proliferation of MSI colorectal cancer cells and stably maintained the microsatellite state in MSI colorectal cancer. Tea polyphenol inhibited the gene expressions of HES1, JAG1, MT2A and MAFA, up-regulated the gene expression of BAX and down-regulated that of P38. Further research is required to investigate how these pathways are interrelated.

AIM: To investigate the effect of puerarin on diabetic myocardial damage and to explore its possible mechanisms in rats. METHODS: The male Sprague-Dawley rats were randomly divided into normal control group, diabetic group, high dose puerarin (160 mg/kg), middle dose puerarin (120 mg/kg), low dose puerarin (80 mg/kg) treatment groups and aminoguanidine (100 mg/kg) treatment group. Corresponding drugs were intraperitoneally injected once a day. The animals in normal control group and diabetic group were given equal propylene glycol. 12 weeks later, the rats were sacrificed and their cardiac muscles were collected. Myocardial structure was observed under transmission electron microscope (TEM). The blood glucose concentration and the activities of superoxide dismutase (SOD), Ca~(2+)-ATPase, Na~+-K~+-ATPase and the content of malondialdehyde (MDA) in myocardial homogenate were measured biochemically. In addition, the mRNA expressions of peroxisome proliferator activated receptor γ (PPAR-γ), glucose transporter-4 (GLUT-4) and aldose reductase (AR) in myocardial tissues were determined by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: It is observed that the myofibrils were diminished, broken or fused, some lipid droplets deposited in the cytoplasm of cardiocytes and part of cristae of mitochondria were broken or disappeared under TEM in diabetic group. The activities of SOD, Ca~(2+)-ATPase, Na~+-K~+-ATPase as well as the mRNA expressions of PPAR-γ and GLUT-4 decreased significantly (all P<0.01). The blood glucose concentration and the MDA level and the AR mRNA expression increased obviously (all P<0.01) in diabetic group as compared to those in normal control group. How-ever, in puerarin treatment groups, the above changes were reversed, a significant differences of those were found as compared to those in diabetic group (P<0.05 or P<0.01, respectively). The pathological change of cardiac muscles was relieved. It showed that myofibrils were well-arranged and only few lipid droplets deposited in the cytoplasm of cardiocytes and most mitochondria had clear and regular cristae under TEM in puerarin treatment groups. CONCLUSION: Puerarin exerts preventive and remedial effects on the diabetic myocardium, which may be related to up-regulating the mRNA expressions of PPAR-γ and GLUT-4, promoting glucose uptake and relieving oxidative stress damage.

Hilar cholangiocarcinoma is a common bile duct cancer.The radical resection rate of end-stage malignancies reported in literature is about 20％.Half of the patients have lost the chance of operation at the time of care,while the average survival time in the patients who can not be operated is about six months.Therefore,for most patients,looking for a palliative treatment which can prolong the survival time is particularly important.From June 2013 to June 2014,our hospital applied iodine-125 brachytherapy,to treat 7 patients with unresectable hilar cholangio carcinoma.All the patients are still alive,the average survival time of 7 patients is 5.2 months up to now,with median survival time being 7.8 months,and longest survival time being 12 months.With good outcomes,few complications,as well as significantly prolonged survival time,iodine125 brachytherapy is regarded with broad clinical applications.

AIM: To explore the activative effect of water extract from cultured mycelium of Paecilomyces cicadae (P. cicadae) on peritoneal macrophages (PM?) and alveolar macrophages (AM?) of rats.METHODS: The rats were randomly divided into four groups: normal control group(Ⅰ), cyclophosphamide (Cy) group (Ⅱ), P. cicadae group(Ⅲ), Cy+ P.cicadae group(Ⅳ).The rats were bred in the same circumstance and were administered with corresponding drugs by subcutaneous injection for 26 days. PM? and AM? of rats were irrigated by normal saline and collected by centrifuge and incubated in a humidified incubator for 2 h at 37 ℃. The activities of acid phosphatase (ACP) and lactate dehydrogenase (LDH) in the PM? and AM? were determined by biochemical methods, and the capability of PM? and AM? in phagocytosis of neutral red were measured by colorimetric method too. RESULTS: After administering P. cicadae to rats, the activities of ACP and LDH in PM? and AM? of normal rats were elevated significantly,and the reduction of the activities of ACP and LDH in PM? and AM? of rats due to Cy was notably antagonized, and the capability of PM? and AM? phagocytizing the neutral red were strengthened significantly.CONCLUSION: P. cicadae can activate the PM? and AM? of rats.
