Objective: To explore the quality of life and drug toxicity in NSCLC (non-small cell lung cancer) patients who have a ECOC (Eastern Cooperative Oncology Group)-PS (performance status) score ≥3 and a response to gefitinib more than 6 months, and to explore the possibily of gefitinib applying in NSCLC patients with a ECOG-PS score ≥3. Methods: NSCLC patients histologically and (or) cytologically confirmed were divided into trial group (ECOG-PS score ≥3) and control group (ECOG-PS score ≤2). The patients in the two groups were treated with a dose of 250 mg/d gefitinib. The efficacy, change of quality of life and the toxicity were evaluated. Results: Eighty-eight NSCLC patients were enrolled in this study (trial group: n = 27; control group: n = 61). The median follow-up time was 20.0 months. All patients in the two groups could be évaluable. In the trial group, 4 (14.81%) patients obtained CR (complete response), 20 (74.07%) patients obtained PR (partial response), 3 (11.11%) patients obtained SD (stable disease); the response rate was 88.89% (24/27). In the control group, 10 (16.39%) patients obtained CR (complete response), 43 (70.49%) patients obtained PR (partial response), 8 (13.11%) patients obtained SD (stable disease); the response rate was 86.89% (53/61). There was no difference in response rate between the two groups (P = 0.794). The median time to symptom improvement of the trial group and the control group were 10.0 and 14.0 d, respectively (P = 0.073), the median PFS (progression-free survival) were 8.0 and 7.0 momths, respectively (P = 0.421). The 1-, 2- and 3-year survival rates were 59.269% (16/27), 25.93% (7/27) and 3.70% (1/27) in the trial group and 57.38% (35/61), 21.31% (13/61) and 6.56% (4/61), respectively. There was no difference in survival rate between the two groups (P = 0.180). The ECOG-PS score after gefitinib therapy (vs before gefitinib therapy) was significantly decreased in the two groups (Trial group Z = -4.062, P = 0.000; Control group Z = -4.031, P = 0.000), and the percent decrease of ECOG-PS score after gefitinib therapy in the trial group was significantly higher as compared with that in the control group. The toxicities of gefitinib therapy were tolerated. Conclusion: Gefitinib can be safely applied in NSCLC patients with ECOG-PS score ≥3. There is no difference in survival time between NSCLC patients with ECOG-PS score ≥3 and ≤2, but the quality of life in NSCLC patients with ECOG-PS score 2= 3 is significantly impoved as compard with NSCLC patients with ECOG-PS score ≤2 after gefitinib therapy.

It is suggested that health educationfor residents especially students should be strengthened to improve their conscious for disease prevention.

AIM: To analyze the effect of myopic adolescents wearing orthokeratology lens on the corneal surface curvature radius and anterior chamber depth.METHODS: Totally 120 cases of adolescent myopia were selected, among them 58 cases with 116 eyes were divided into 11-14 years old group and 62 cases with 124 eyes were 15-18 years old group according to the age.They were treated with long-term orthokeratology lens treatment, and two groups of patients were observed before wearing lens(T0), wearing for 6mo (T1), 12mo (T2) for uncorrected visual acuity, the average refractive degree improvement, the central corneal thickness, corneal curvature changes and the incidence of complications.RESULTS: The uncorrected visual acuity of the two groups at 12mo after wearing were better than that at 6mo which was better than that before wearing;the diopter had the same trend.The uncorrected visual acuity and the diopter of the 11-14 years old group at 6 and 12mo was better than those of 15-18 years old group with significant difference (P<0.05).The central corneal thickness of the two groups at 12mo after wearing were less than that at 6mo which was less than that before wearing.There was no significant difference of the central corneal thickness between the two groups at 6 and 12mo after wearing (P>0.05).The corneal anterior surface curvature of the two groups at 12mo after wearing were more than that at 6mo which was more than that before wearing.The axial length of the 11-14 years old group was longer than that of the 15-18 years old group with significant difference (P<0.05).There was no significant difference on the corneal posterior surface curvature of the two groups before and after wearing (P>0.05).There was no significant difference on the anterior chamber depth between the two groups at different time or between before and after wearing (P>0.05).CONCLUSION: Long-term wearing orthokeratology lenses have a significant effect for control ling juvenile myopia, and can improve the corneal anterior surface curvature, especially in the lower age group, and has no significant effect on the anterior chamber depth.

AIM:To study the clinical effect of silica gel drainage tube combined with lomefloxacin hydrochloride eye ophthalmic gel in the treatment of lacrimal duct obstruction.METHODS:Totally 86 cases (138 eyes) of lacrimal duct embolism treated in our hospital from February to December 2015 were divided into 43 cases (68 eyes) as control group and 43 cases (70 eyes) of the observation group according to whether they were treated with lomefloxacin hydrochloride eye ophthalmic gel.Patients in the control group were treated with silica gel drainage, while the observation group was treated with lomefloxacin hydrochloride eye ophthalmic gel on the basis of the control group.The total effective rate, serum hypersensitivity C-reactive protein (h-CRP) level, complications and recurrence rate were observed and compared between the two groups.RESULTS:The total effective rate in the patients with obstructive nasolacrimal duct, common lacrimal duct obstruction, and lacrimal duct obstruction in observation group were 95.2%, 100.0%, 96.7%, higher than those in control group (P<0.05).There was no significant difference between the two groups in preoperative serum h-CRP levels (P>0.05).The serum levels of h-CRP in patients in the observation group at 3d and 7d after operation respectively were 2.40±0.84g/mL, 1.94±0.84g/mL, lower than those of control group at the same time (P<0.05).The complication rate of the observation group was 1.4%, which was lower than that of the control group (P<0.05).Follow up for 6-18mo, the recurrence rate was 11.4% in the observation group, which was significantly lower than the control group (P<0.05).CONCLUSION:The combination of silica gel drainage tube and lomefloxacin hydrochloride eye ophthalmic gel in the treatment of obstruction of lacrimal duct has good clinical efficacy, low inflammatory reaction, low complication rate and low recurrence rate.

Objective To observe and evaluate the effect of ultrasound guided percutaneous ethanol injection for hyperparathyroidism secondary to chronic renal failure. Methods Fifty-three patients with secondary hyperparathyroidism in Nanjing General Hospital Military Command from January 2011 to May 2013 were treated by percutaneous ethanol injection. The echogenicity, size and blood supply of parathyroid glands were observed by color Doppler ultrasound before and after treatment. Parathyroid hormone (PTH) and volumes of parathyroid glands were analyzed and compared with non-paired t test. Results Before treatment, the parathyroid gland volume was (5.28±0.84) cm3. The enlarged parathyroid glands had homogeneous hypoechogenicity and abundant blood supply, and the PTH was (1041.6±37.1) ng/L. After treatment, the size of solitary parathyroid gland was (3.93±0.67) cm3 which did not change significantly compared with that before treatment. The echogenicity of parathyroid glands enhanced and blood supply decreased after injection ethanol into solitary parathyroid. PTH [(509.2±27.6) ng/L] decreased obviously (t=3.792, P < 0.05). Conclusion Color Doppler ultrasound guided percutaneous injection of ethanol has an important role in the treating of secondary hyperparathyroidism and the curative effect can be observed timely.
