To investigate the clinical efficacy and safety of phototherapeutic keratectomy ( PTK ) in the treatment of bullous keratopathy ( BK) .METHODS: A retrospective analysis of 60 cases ( 60 eyes) of BK patients from Department of Ophthalmology in our hospital October 2011 to July 2014 was undergone. Clinical data of all patients with treatment of PTK were analyzed. Best corrected visual acuity ( BCVA ) , corneal curvature, corneal astigmatism, corneal thickness and corneal endothelial cell density ( ECD ) , postoperative complications before and after surgery were compared. RESULTS: BCVA, corneal curvature, corneal astigmatism of patients before surgery were 0. 05 ± 0. 01 and 37. 02±5. 38, 1. 08±0. 67D, which were significantly less than those of postoperative ( respectively 0. 45 ± 0. 13 and 46. 27 ± 7. 02, 1. 92 ± 0. 73D ), the differences were statistically significant (all P<0. 05). Corneal thickness of patients was 492. 33 ± 18. 27μm before surgery, which was higher than that after surgery 377.27±22.49μm (P<0.05). The difference of visual acuity before and after surgery was statistically significant in this group (P<0. 05). During the follow-up period of 6mo, no recurrence of the original corneal lesions, only 2 cases of postoperative slight haze, it was completely dissipated after given the hormone eye drops.CONCLUSlON: Excimer laser technology has high safety in the treatment of bullous keratopathy, it should be promoted in clinical practice.

Objective To evaluate the antitumour efficacy of shRNA plasmid specifically targeting Jab1 gene.Methods The nude mouse tumor model was made by subcutaneous injection of human laryngeal carcinoma Hep-2 cells.The tumor growth was monitored after intratumoral injection of pJab1,pKB plasmids and saline.Jab1 and p27 expressions in tumour tissues were examined by immunohistochemistry stainingand RT-PCR.Results Mean volume of the pJab1 -treated tomors was(267.60 ± 88.19) mm3,significantly less than that of tumors treated with pKB plasmids( 832.20 ± 140.39)mm3 or saline(895.40 ± 145.93) mm3( F =36.73,P ＜ 0.001 ).Immunohistochemistry showed that the expression of Jab1 protein was significantly reduced in the pJab1-treated group(32.40％ ± 5.59％) compared to the control groups,whereas the expression rate of p27 protein in the pJab1 group(76.80％ ±6.30％ ) was significantly increased compared to the control groups( P ＜ 0.001 ).The down regulation of Jab1 protein by pJab1 plasmid was consistent with mRNA expression confirmed by RT-PCR.The level of Jab1 mRNA level in the pJab1-treated group( 0.65 ±0.03) was significantly lower than the control groups(F=558.00,P＜0.001),however,p27 mRNA,was 0.80 ±0.02,had no significant alteration(F=1.52,P＞0.05).Conclusions The pJab1 plasmid results in downregulation of Jab1 in an xenograft tumour model of human laryngeal carcinoma Hep-2 cells and significantly inhibits the tumour growth in vivo.This suggests that pJab1 plasmid specifically targeting Jab1 gene expression could be an effective therapy for human laryngeal carcinoma.

AIM: The study was undertaken to investigate the effort of Dexamethasone (DEX) on cultured rabbit corneal epithelial (RCE) cells and rabbit corneal epithelial wound healing.METHODS: For the in vitro experiments, primary cultures of RCE cells were used. DEX in different concentrations was added to cultured RCE cells. The effects were measured with tetrazolium salt (MTT)method and flow cytometry. For the in vivo wound-healing experiments, a central corneal deepithelialization was created and were treated with 0.1g/L DEX eyedrop randomly explain how randomly. Epithelial wound healing was evaluated clinically and analyzed histopathologically using light microscopy along with immunohistochemical staning and electronic microscopy.RESULTS: Less than 0.1g/L DEX didn't influence survival rate in cell culture conditions by MTT assay. Flow cytometric studies revealed that 0.1g/L DFX had no effect on cellular growth phase in cultured rabbit corneal epithelial cells. The mean time of the epithelial healing was significantly shorter in the DEX-treated group than in the control group at 24h. There were strong proliferative-cell-nuclear-antigen(PCNA) expressions in newly generated epithelial cells of both groups. The Dex-treated group had a more regular architecture of stromal lamella and significantly less inflammatory response than the control group under electronic microscopy.CONCLUSION: Less than 0.1g/L DEX had no inhibiting effect on cultured rabbit corneal epithelial cell growth.0.1g/L DEX eye drops can effectively promote epithelial growth and reduce inflammatory response, which may have useful clinical application at the early stage of corneal wound healing process.

Objective To assess iodine nutrient levels of vulnerable population in Linxia Hui Autonomous Prefecture of Gansu. Methods Local pregnant, lactation, child-bearing age women and 0 - 3 years old infants were selected. The urinary iodine (UI) were determined by arsenic-Ce catalytic spectrophotometry (WS/T 107-1999) and salt iodine content was determined using direct titration method (GB/T 13025.7-1999). The development quotient (DQ) among 0 - 3 years old infants were surveyed by the scales of neuropsychologists development among 0 - 6 years old, and their body height and weight were then investigated. Results The consumption and coverage rates of iodized salt at household level were all below than 90% in 5 counties among 8 counties. The median urine iodine (MUI) among pregnant, lactation, child-beating age women and 0 - 3 years old infants were 90.17, 89.28, 84.85 and 107.28 μg/L, respectively. The UI proportion less than 50 μg/L were 29.6%(278/938), 30.7%(239/778), 32.2% (265/824), and 23.9%(252/1056), respectively. The UI proportion equal or more than 50 μg/L and less than 100 μg/L were 25.1%(235/938), 24.0%(187/778), 23.7%(195/824), 23.7%(250/1056). MUI in pregnant were all less than 150 μg/L in 8 counties, and MUI in lactation women were less than 100 μg/L in 6 counties. The DQ median of infants 0 - 3 years old was 93.0, and 59.9%(395/659), 34.4%(227/659) and 5.6%(37/659)had a DQ below middle, at middle and above middle, respectively. Forty point seven percent (266/654), 50.2%(328/654) and 9.1% (60/654) had a body height below middle,at middle and above middle, respectively. Thirty-five percent (232/663), 51.3%(340/663) and 13.7%(91/663) had a body weight below middle, at middle and above middle, respectively. Conclusions The local qualified iodized salt consumption rate and iodized salt coverage rate are still low. The urine iodine level is below than the reference value recommended. The iodine nutrient is not enough among iodine deficiency disorder vulnerable population, especially in pregnant and lactation women. Infants growth development is retarded.

Objective To explore whether the degree of 99Tcm-methoxyisobutylisonitrile (MIBI) uptake in non-small cell lung cancer (NSCLC) could be correlated with the treatment response to three-dimensional conformal radiotherapy.Methods A total of 102 patients with NSCLC were studied with 99Tcm-MIBI SPECT before radiotherapy.The patients were classified by a follow-up CT as responders (complete or partial remission) and non-responders (stable or progressive disease).After intravenous administration of 740 MBq 99Tcm-MIBI, SPECT imaging at 10-30 min (early) and 2-3 h (delayed) were performed.Region of interest (ROI) was placed over the tumors and contralateral normal lung tissue.The uptake ratio of tumor to contralateral normal lung (T/N) was obtained from both early (ER) and delayed (DR) SPECT images.The retention index (RI) was measured as:RI = (DR - ER)/ER×100%.Statistical analysis was performed by two independent-sample t-test and Mann-Whitney U test using software SPSS 13.0.Results 99Tcm-MIBI uptake was significantly higher in responders than in non-responders:2.36 ±0.17 vs 1.82 ±0.14 (ER) and 2.48 ± 0.20 vs 1.94 ± 0.16 (DR), respectively (t = - 13.1,- 12.7, both P＜ 0.05).The median RI in the responders group was also significantly higher than that in the non-responders group (6.60% vs 5.13%, z = - 6.83, P ＜ 0.05).Conclusion ER, DR and RI of 99Tcm-MIBI SPECT might be useful to estimate the treatment response to three-dimensional conformal radiotherapy in patients with NSCLC.

Objective To study the effective hemostatic method for treating multiple trauma accompanied with hemorrhagic shock to increase the existence rate. Methods In treating 5 patients of multiple tauma accompanied with hemorrhagic shock, We used radiological embolism to injuried parenchymatous organs and injuried vessels to arrest the bleeding at first. After shock recovered, prompt exploration was made to repair injuried hollow viscus. Results After embolism and bleeding arrested, shocks in all 5 patients were corrected in short time; and no serious active hemorrhage was found after abdominal operation to repair the hollow viscus. All 5 patients survived after the operation. Conclusions The radiological embolism is simple,and has the little trauma and a good hemostatic effect,and needs short time. The method for treating multiple trauma can improve the salvage rate of multiple trauma accompanied with hemorrhagic shock and fit the treatment principle of multiple trauma.
