International Eye Science 2016;16(10):1965-1967
AIM: To investigate the efficacy of 1g/L topical cyclosporine A ( tCsA ) in preventing the recurrence of pterygium after pterygium excision and conjunctival flap rotation technique.
●METHODS:Fifty-eight patients (58 eyes) with primary pterygium were included in this prospective study. All eyes were operated with pterygium excision and conjunctival flap rotation technique, and divided into treatment and control group according to whether be treated with 1g/L tCsA eye drops after operation. The operated patients were followed up for 1y to assess the recurrence of pterygium.
●RESULTS: After surgery, the difference between the tCsA treatment and control group were statistically significant in the Schirmer l test results (9. 93 ± 1. 59mm/5min vs 8. 47±1. 53mm/5min, P<0. 001). The Schirmer l test results increased after tCsA treatment for patients assigned to the treatment group. The pterygium recurred in 3 of 28 eyes (10%) in the treatment group and 11 of 30 eyes (39%) in the control group (P=0. 029).
●CONCLUSION:tCsA eye drops are safe and effective for medical treatment to reduce rates of recurrence after pterygium surgery.

OBJECTIVETo observe the effect of Draconis Sanguis-containing serum on the expressions of NGF, BDNF, CNTF, LNG-FR, TrkA, GDNF, GAP-43 and NF-H in Schwann cells, and investigate the possible mechanism of Draconis Sanguis to promote peripheral nerve regeneration.
METHODSD rats were randomly divided into 2 groups: the Draconis Sanguis group (orally administered with Draconis Sanguis-containing balm solution) and the blank group (equivoluminal balm) to prepare Draconis Sanguis-containing serum and blank control serum. Schwann cells were extracted from double sciatic nerves of three-day-old SD rats, divided into 2 groups: the Draconis Sanguis group and the blank control group, and respectively cultured with 10% Draconis Sanguis-containing serum or blank control serum. The mRNA expressions of NGF, BDNF, CNTF and other genes in Schwann cells were measured by RT-PCR analysis 48 hours later.
RESULTMost of the Schwann cells were bipolar spindle and arranged shoulder to shoulder or end to end under the microscope and identified to be positive with the immunocytochemical method. To compare with the blank group, mRNA expressions of NGF, LNGFR, GDNF and GAP-43 significantly increased (P < 0.01). Whereas that of BDNF decreased significantly (P < 0.05), and so did that of TrkA, CNTF (P < 0.01), with no remarkable difference in NF-H-mRNA.
CONCLUSIONTraditional Chinese medicine Draconis Sanguis may show effect in nerve regeneration by up-regulating mRNA expressions of NGF, LNGFR, GDNF and GAP-43 and down-regulating mRNA expressions of TrkA, BDNF and CNTF.

Aim To elucidate the molecular mechanism of cell cycle arrest and apoptosis of MCF-7 cells induced by paclitaxel. Methods Flow cytometry was used to determine the cell cycle changes of MCF-7 cells upon paclitaxel treatment. Gene expression profiles of MCF-7 cells induced by paclitaxel were obtained by using cDNA microarrays containing 9 984 genes and expressed sequence tags (ESTs).Results Cell cycle analysis showed that 77.8% of cells arrested at G2/M phase and 1.3% of cells caused G2/M cell cycle arrest and apoptotic cell death in a concentration-dependent manner, which is associated with the regulation of selected genes related to microtubule assembly and cytoskeleton, cell cycle regulation, and DNA repair and apoptosis.

Objective To investigate the expression of peripheral blood (PB) CD4+ CD25+ Foxp3+ regulatory T cells (Tregs) in patients with benign end-stage liver disease after liver transplantation and the relationship between levels of PB Tregs and acute rejection. Methods A prospective analysis was performed on 55 consecutive patients who underwent liver transplantation.Fourteen out of 55 cases suffered from acute rejection after liver transplantation were defined as rejection group,while the rest patients were classified into no acute rejection group. PB was obtained from liver transplant patients at different time points longitudinally: pre-transplant, post-transplant within one year and acute rejection. The circulating CD4+ CD25+ Foxp3+ Tregs in PB were measured by flow cytometry. Blood samples were drawn during acute rejection, at the same time, liver biopsies were performed. The circulating CD4+ CD25+ Foxp3+ Tregs were compared between two groups.Results There was no difference between two groups in levels of circulating CD4+ CD25+ Foxp3 + Tregs cells pre-transplant. However, the levels of circulating CD4+ CD25+ Foxp3+ Tregs in rejection group were decreased significantly as compared with no-rejection group (2. 23 % ± 0. 54 % vs. 2. 99 % ±0. 86 %,P<0.01). The frequency of CD4+ CD25+ Foxp3+ T cells was negatively correlated with rejection activity index (RAI) (r = - 0. 80, P<0. 01 ). Conclusion Monitoring PB CD4+ CD25+ Foxp3+ Tregs levels may be helpful in evaluating the immune state and act as a more sensitive marker for acute rejection diagnosis in the patients following liver transplantation.

Objective to investigate the feasibility and outcomes of different surgical treatments for adrenal metastasis after previous radical ne-phrectomy for patients with renal cell carcinoma. Methods A total of 18 adrenal solitary metastasis of renal cell carcinoma were identified from da-tabase of two institutions between 2003 and 2013. Clinical and pathologic data were collected and analyzed. Results Of 9 patients who had ipsilater-al metastasis of the renal tumor,the estimated blood loss were obviously fewer in the transperitoneal LA group. Of 9 cases who had contralateral me-tastasis of the renal tumor,the fasting time[(1.4±0.8)h vs(4.0±1.4)h,P = 0.036]and length of hospital stay[(4.5±1.2)d vs(7.0±4.5)d,P =0.041]were obviously fewer in the retroperitoneal LA group. the averages of the fasting time and length of hospital stay in the retroperitoneal LA group were obviously smaller than in the transperitoneal LA group. Conclusion LA for treatment of renal cell carcinoma metastasis is technically feasible in selected patients. transperitoneal and retroperitoneal LA can be respectively recommended as an appropriate approach for isolated adrenal metastases of ipsilateral and contralateral renal cell carcinoma after nephrectomy.
