New technologies and ideas are constantly emerging recently. With the arrival of the era of minimally invasive surgery, most of the colorectal cancer surgeries can be conducted through minimally invasive techniques. In this study, we discuss the status, characteristics, controversy, and consensus of minimally invasive techniques in colorectal cancer surgery.

Objective To investigate the expression of uPAR and VEGF-C in hepatocellular carcinoma (HCC) and its effect on the biological behavior of HCC. Methods The expression of uPAR and VEGF-C in liver tissue specimen of 33 patients with HCC was detected by immunohistochemical staining. Results The positive expression of uPAR and VEGF-C in HCC tissues was located in cytoplasma of cancer cells. The positive rates of uPAR and VEGF-C were 69.7 %(23/33) and 78.8 %(26/33) respectively in 33 cases of HCC. The expression rates of uPAR and VEGF-C were significantly higher in HCC with metastasis than in HCC without metastasis(P<0.05). But there were not significant correlation between the expression of uPAR or VEGF-C and tumor size, tumor grade, AFP level, hepatic cirrhosis. There was a close correlation between uPAR and VEGF-C in HCC(r=0.676, P<0.01). Conclusion The expression of uPAR and VEGF-C is correlated with metastasis, uPAR and VEGF-C may be signs of aggressive phenotype for evaluating treatment and prognosis of HCC. Examination of these two proteins may be helpful to .judge biological behavior of HCC.

Objective To study the expressions of matrix metalloproteinase-3 (MMP-3) and osteopontin (OPN) in cervical carcinoma and their relationship with invasion and metastasis. Methods The expression of MMP-3 and OPN were detected in 54 cases of cervical cancer tissues by immunohistochemical SP method. Compared with 15 cases of normal cervical tissues, the relationship was analyzed between both protein expressions and clinical pathology. Results The expression positive rates of MMP-3 and OPN in cervical cancer tissues (70.37 % and 66.7 %, respectively) were significantly higher than those of normal cervical tissues (20 % and 0, respectively), were significantly higher with infiltration depth >1/2 and lymph node metastasis than those with depth≤1/2 and without metastasis , respectively(P <0.05). The expressions of MMP-3 and OPN were related with depth of cervical infiltration and lymph node metastasis of cervical cancer.Expressions between MMP-3 and OPN were significantly positively correlation(r =0.401, P<0.05). Conclusion The expressions of MMP-3 and OPN are correlated with invasion and metastasis of cervical carcinoma.

Objective To investigate whether HBx alone is sufficient to directly transform the nontransformed immortalized human liver cell line QSG7701 and induce hepatocellular carcinoma in vivo,and to explore preliminarily the pathogenic mechanism of transplantation tumor in nude mice.Methods The pCMVX/QSG7701 cells were vaccinated into subcutaneous tissue of nude mice.The pRcCMV2/QSG7701 and QSG7701 Cells were used as control.At the fifth weeks after vaccination,the nude mice were killed to observe whether a tumor was formed.The activity state and food intake of the nude mice was recorded.The texture,volume,and metastasis of transplantation tumor were observed grossly.The transplantation tumor was observed microscopically on the hematoxylin and eosin (HE) staining section.Immunohistochemical surfactant protein (SP) method was used to analyze the protein expression of mutant p53 and C-Myc genes.Results The transplantation tumor was occurred in all of the six nude mice vaccinated with pCMVX/QSG7701 cells at the second week after vaccination.No metastatic tumor was found in other organs.Transplanted tumor was not formed in all of the negative control groups.HE staining analysis confirmed that the character of transplanted tumor was hepatocellular carcinoma.p53 and C-Myc proteins were expressed in pCMVX/QSG7701,pRcCMV2/QSG7701,and QSG7701 cells,and their expression levels in the pCMVX/QSG7701 cells were significantly higher than those in the pRcCMV2/QSG7701 and QSG7701 cells,respectively(P ＜0.01).Conclusions HBx alone is sufficient to directly transform the non-transformed immortalized human liver cell line QSG7701 and induce hepatocellular carcinoma in vivo through up-regulating the expression of mutant p53 and C-Myc genes.

The most common clinical manifestations of Hashimoto’s thyroiditis (HT) are goiter and hypothyroidism. The biochemical thyroid function varies quite widely among patients. Anti-TPO antibodies (TPOAbs) are the most sensitive index to screen HT. The thyroid function deteriorates gradually, and the hypothyroidism is the permanent sequeala of HT. The natural history of HT in children and adolescents is not fully known, and monitoring of thyroid function for all patients should be long-term. Children with hypothyroidism should be treated with levothyroxine replacement therapy.

Objective To investigate incidence and severity of retinopathy of prematurity (ROP)screened by RetcamⅢ and the related factors.Comparative case series were designed.Methods A study was performed among infants who required screening by RetcamⅢ in the second Affiliated Hospital & Yuying Children's Hospital of Wenzhou Medical University,and carried out between May 2012 and April 2013.A total of 1097 infants met the study criteria,and were divided into group Ⅰ (n =333 from outpatient screening) and group Ⅱ (n =764 from inpatient screening).Variables were recorded,including birth weight (BW),gestational age (GA),number of births (NOB,singleton/twins/triplets),gender,neonatal respiratory distress syndrome (NRDS),patent ductus arteriosus (PDA),neonatal asphyxia,neonatal hyperbilirubinemia,intracranial hemorrhage,congenital heart disease,neonatal anemia,neonatal sepsis,necrotizing enterocolitis (NEC),and bronchopulmonary dysplasia (BPD).The results of ophthalmological examinations by RetcamⅢ were also recorded.Spearman correlation analysis was used to identify the variables most significantly associated with ROP.Results There were 98 infants of ROP in group Ⅱ (total 764,12.8％).There was a significant association of ROP with variables (P ＜0.05),including BW,GA,and NOB.There was a significant association of ROP with diseases (P ＜ 0.05),including NRDS,neonatal asphyxia,intracranial hemorrhage,neonatal anemia,neonatal sepsis,NEC,and BPD.However,there was no association of ROP with diseases (P ＞ 0.05),including PDA,neonatal hyperbilirubinemia,and congenital heart disease.Conclusions RetcamⅢ can be used to screen retina of infants.ROP is still the most common eye disease in preterm infants.The incidence of ROP was 12.83％ in Wenzhou.Variables,including BW,GA,NOB,NRDS,neonatal asphyxia,intracranial hemorrhage,neonatal anemia,neonatal sepsis,NEC,and BPD,were the most significant factors associated with ROP.
