Purpose: To evaluate the efficacy, safety and survival of low molecular weight heparin ( LMWH) plus chemotherapy in patients with advanced non-small cell lung cancer. Methods: 46 patients with NSCLC were randomized into chemotherapy plus LMWH. (study group) and chemotherapy only( control group). Both groups received two cycles of MVP regimen (MMC 6 mg/m2, YDS 3 mg/m2 x 2, DDP 90 mg/m2). Patients in the study group were treated with LMWH 5000u twice daily from the third day before chemtherapy up to 7 days. Results: The response rate was 56. 5% (13/23) for the study group and 39. l%(9/23) for the control group. Median survival time( MST) and 1-year survival rate were 12, 1 months(95%CI:8.52~14.64) and 52.2% for the study group compare 8.4 months(95%CI:6.15 ~ 10. 85) and 34. 8% for the control group. There were significant differences for MST( 12. 1 vs 8. 4) and 1 year survival rate(52. 2% vs 34. 8%) in the study group as compared to the control group. No difference in response rate and toxicities were found between the two groups. Conclusions: Chemotherapy( MVP regimen) plus LMWH is effective and safe. Prolonged survival was observed in patients who received MVP regimen plus LMWH.

Objective To study the interventional therapeutic methods in Budd Chiari syndrome (BCS) complicated with thrombosis. Methods Eighteen patients of BCS complicated with thrombosis, including 2 cases of hepatic vein (HV) occlusion and 16 cases of inferior vena cava (IVC) occlusion, were treated. Therapeutic methods were anti coagulation with Co Danshen and aspirin in 10 cases or the anti coagulation and thrombolysis with urokinase in 8 cases before operation, treatment with PTA and stent during operation,and thrombolysis with urokinase and the anti coagulation after operation. Results Technical success was achieved in all patients without serious complications. The mean blood pressure in IVC dropped from (31 82?0 52)cm H 2O(1 cm H 2O= 0 098 kPa) to (18 17?0 38)cm H 2O immediately after the procedure. The blood pressure in HV dropped from 42 cm H 2O and 41 cm H 2O to 15 cm H 2O and 16 cm H 2O, respectively. All 18 cases were followed up for an average of 38 months (range 6-72 months). The main symptoms and signs completely disappeared in 12 cases and partially alleviated in 6 cases. Conclusion The interventional treatment of BCS complicated with thrombosis was a safe and effective method.

Background Epipolis laser in situ keratomihusis(Epi-LASIK) is an potential surgery for myopia because it synthesize advantages of LASEK and LASIK. But its clinical effectiveness and safeness is remarkable.Objective This study was to evaluate the clinical curative effects and safeness of Epi-LASIK for myopia in different diopter of population. Methods Retrospective study was designed for 208 eyes of 104 patients who underwent EpiLASIK for the correction of myopia. The patients were divided into two groups according to preoperative diopter:lower myopia group( ≤ -6.00 D, 111 eyes) and high myopia group ( >-6.00 D,97 eyes). The time of epithelial healing, postoperative syndrome, postoperative visual acuity, refraction, intraocular pressure (IOP) , the safe index, the efficacy index and haze were evaluated at 1,3,6,12 months postoperatively. The written informed consent was obtained from each individual before surgery. Results After operation, 20 eyes ( 18.02% ) of lower myopia group and 29 eyes (29.90%) of high myopia group had obvious pain, presenting statistically significant difference between two groups (X2 = 4. 060, P<0.05 ). The mean time of epithelial healing was (5.49±0. 83 )days in lower myopia group and (5.85± 0.68 )days in high myopia group with a delayed epithelial healing time in high myopia group( u= 3. 377 ,P<0.05 ).One year after the treatment,the uncorrected visual acuity( UCVA ) ≥ 1. 0 was 90. 99% ( 101 eyes) in lower myopia group and 75.26% ( 73 eyes) in high myopia group, and 9.91% ( 11 eyes) and 15.46% ( 16 eyes) of the eyes improved byl line or more in best spectacle corrected visual acuity(BCVA) ;whereas 3.60% (4 eyes)and 6. 18% (6 eyes)lost a line or more. 91.89% ( 102 eyes) and 85.57% (83 eyes) in both groups gained within 1.00 D of the attempted correction. The safety index and efficacy index were 1.04 and 0. 98 in lower myopia group,and 1. 01 and 0. 96 in high myopia group without statistically significant difference( P>0. 05 ). haze occurred in 6 eyes in lower myopia group and 9 eyes in high myopia group and the difference in haze grading was not statistically significant between two groups ( P>0. 05 ). The high intraocular pressure appeared in 10 eyes and 9 eyes in low myopia group and high myopia group respectively during the fellow up duration and back to normal after topical use of timolol. Conclusion Epi-LASIK is an effective and safe method for correction of different diopters of myopia because of its mild symptom and lower incidence of haze.
