· AIM: To study the expression of basic fibroblast growth factor (bFGF) receptor protein in human lens epithelial cells (HLECs). METHODS: Immunohistochemistry was used to detect the level of bFGF receptor protein and image analysis was adopted to perform the relative quantitative analysis on it. · RESULTS: There was bFGF receptor protein in HLECs accordingl to both qualitative and quantitative analysis. · CONCLUSION: bFGF receptor protein exists in HLECs and it is the material foundation for bFGF to improve the proliferation of HLECs.

Objective To study the clinical application of the lung lesion biopsy through helical CT-guided fine needle aspiration. Methods 44 cases of lung lesions were pathologically biopsy diagnosed through helical CT-guided fine needle aspiration. Results All 44 lung lesions were successfully conducted biopsy through CT-guided fine needle aspiration, and the pathological confirmed diagnosis rate was 98%. Conclusion With high diagnosis rate, CT- fine needle aspiration is clinically applicable and the complication is rare. It is easily-operated, safe and economical.

Objective To study the diagnostic value of CT combined with serum carbohydrate antigen 19-9(CA19-9), carcinoembryonic antigen(CEA), carbohydrate antigen 125(CA125)in diagnosis of pancreatic cancer.Methods 68 patients with pancreatic occupying lesions were selected and they were divided into pancre -atic cancer group(n=43)and non-pancreatic cancer group(n=25)according to pathological diagnosis.34 cases from physical examination were set as the control group .All patients received CT examination and the consistency between CT diagnosis and pathological results was analyzed .Serum CA19-9, CEA, and CA125 were detected by chemiluminescence method.The sensitivity, specificity and accuracy of CT combined serum CA 19-9, CEA, CA125 were analyzed.Results Among the 68 cases, 35 cases were pancreatic cancer diagnosed by CT , and the CT diagnosis was not ideal compared with pathological results .Nonparametric test found that serum CA 19-9, CEA and CA125 in pancreatic cancer group were higher than those of the non-pancreatic cancer group and the control group, and the difference had statistical significance ( P<0.05 ) , while the difference between non-pancreatic cancer group and the control group had no statistical significance ( P>0.05 ) .Conclusion CT diagnosis had high susceptibility and low specificity ,CT combined with serum CA19-9,CEA, and CA125 can improve accuracy of pancreatic cancer diagnosis .

AIM:To observe the transplantation of acellular porcine corneal stroma on the treatment of superficial keratitis by drug-resistant fungal.METHODS:We performed a retrospective analysis of 16 cases of fungal keratitis received the transplantation of acellular porcine corneal matrix from June 2015 to March 2016 with a follow-up of 6mo.We analyzed on items as postoperative visual acuity, corneal graft status, postoperative recurrence and postoperative complications.RESULTS:We observed a healing time of corneal epithelium in 7 to 10d postoperatively generally and the absence of corneal edema in 1mo, while the cornea gradually returned transparent in the 16 cases.Two cases required medication for an epithelial recovery and 3 cases received intervention for decreasing intraocular pressure to a certain level.During the follow-up we observed no cases of cornea degeneration, recurrence of infection or rejection.The vision acuity showed 1.27±0.22, 1.11±0.13, 0.79±0.22 in 1, 3 and 6mo after operation respectively.There was no statistical difference between vision in 1mo and the vision before surgery (P=0.06);while we found a statistical difference when comparing the vision of 3 and 6mo with vision before surgery (P=0.01,0.001).The vision in 6mo increased with a statistic difference to the vision at 1 and 3mo (P<0.001) while no statistic difference was observed between 1 and 3mo(P=0.11).CONCLUSION:Transplantation of acellular porcine corneal matrix is a safe and efficient treatment for fungal keratitis.

AIM:To study the differences of basic fibroblast growth factor(bFGF)gene expression in lens epithelial cells (LECs) between fetuses and cataract patients. METHODS: In situ hybridization was used to detect bFGF mRNA in the LECs that were cultured and in tissue sections from fetuses and in the LECs from the anterior capsule of cataract patients. Image analysis was used for the relative quantitative analysis of bFGF mRNA. RESULTS: bFGF gene existed in the LECs that were cultured and in tissue sections from fetuses and in the LECs from the anterior capsule of cataract patients. The integral absorbance for the fetal cultured cells, the fetal tissue sections and the capsule membrane cells of cataract patients were 627.1±268.7, 131.5±42.8 and 79.2±26.3 respectively. The integral absorbance of fetal cultured LECs was significantly higher than that of fetal section LECs (P<0.01). The integral absorbance of cataract LECs was significantly lower than that of fetal LECs (P<0.01). CONCLUSION: The in vitro culture of LECs can improve bFGF gene expression. The bFGF gene expression in fetal LECs is significantly higher than that in cataract LECs.

Subtelomeric rearrangements contribute to idiopathic mental retardation (MR), but most children with idiopathic MR do not show any chromosome abnormalities with standard cytogenetic analysis. The primed in situ labeling (PRINS) technique, using an oligonucleotide primer complementary to the telemetric repeat sequences (TTAGGG), can identify chromosome telomeric abnormality (deletion) in idiopathic MR children. In this study, seventy children with idiopathic MR were enrolled and subjected to PRINS. The results showed normal karyotype in all the children, subtelomeric rearrangements (1q del and 4q del) in 2 cases, which was confirmed by fluorescence in situ hybridization (FISH). It was concluded that PRINS is effective for the detection of subtelomeric rearrangements and may become a routine technique for cytogenetical abnormality screening.
