ABSTRACT
Objective To discuss the correlation between family history of malignant neoplasms (MN-FH) and the clinicopathological features of patients with non-small cell lung cancer (NSCLC). Methods The clinicopathological data of 326 patients with NSCLC in Yangzhou University Affiliated Hospital from June 2016 to June 2018 were analyzed retrospectively. The patients were divided into two groups based on with or without MN-FH, and the clinicopathological features of the two groups were analyzed by χ 2 test. Results Of the 326 patients with NSCLC, 41 (12.6％) were in the MN-FH group and 285 (87.4％) in the MN-FH group. There were no significant differences in sex, age, smoking, location of tumors and histological classification between patients with or without MN-FH (χ 2 values were 0.031, 0.769, 0.546, 0.117, and 0.945, all P > 0.05), but in patients with MN-FH, the proportion of tumor diameter < 5 cm [65.9％ (27/41) vs. 42.5％(121/285), χ 2 = 14.173, P < 0.05], undifferentiation and low differentiation [70.7％ (29/41) vs. 53.7％(153/285), χ 2 = 4.224, P < 0.05], TNM stage Ⅲ+Ⅳ [65.9％ (27/41) vs. 46.7％ (133/285), χ 2 = 5.280, P <0.05], lymph node metastasis [78.0％ (32/41) vs. 60.0％ (171/285), χ 2 = 4.970, P < 0.05], distant metastasis [75.6％ (31/41) vs. 53.3％ (152/285), χ 2 = 7.224, P < 0.05], high degree of malignancy [70.7％ (29/41) vs. 51.6％ (147/285), χ 2 = 5.293, P < 0.05] and combination of other tumors [29.3％ (12/41) vs. 7.7％ (22/285),χ 2 = 17.817, P < 0.05] were significantly higher than those in patients without MN-FH. Conclusions NSCLC patients with MN-FH have a higher degree of malignancy. For people with MN-FH, physical examination is very important.
ABSTRACT
Objective To study the expression of ultra-conserved gene sequence uc.454 in non-small cell lung cancer (NSCLC) tissues and its clinical significance.Methods Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression level of uc.454 mRNA in 130 cases of NSCLC and adjacent normal tissues from Affiliated Hospital of Yangzhou University between January 2014 and December 2017,and its association with clinicopathological factors and prognosis of NSCLC patients was analyzed.Results The expression level of uc.454 mRNA in NSCLC tissues was lower than that in adjacent normal tissues (2.98 ±0.96 vs.13.95± 2.23,t =98.441,P ＜ 0.05),and its expression level was associated with tumor infiltration depth (x2 =7.823,P =0.040),TNM stage (x2 =20.719,P ＜ 0.01) and lymph node metastasis (x2 =24.142,P ＜ 0.01).The survival time of patients with low expression of uc.454 mRNA was shorter than that of patients with normal or high expression (26.9 months vs.43.7 months),and the difference was statistically significant (P ＜ 0.05).Conclusion The low expression of ultra-conserved gene sequence uc.454 mRNA is related to the occurrence,development and prognosis of NSCLC.
ABSTRACT
Objective To compare the feasibility,effectivity and security of modified trabeculectomy in advanced stage angle-close glaucoma with cataract.Methods One hundred and forty-five patients (151 eyes) of advanced stage angle-close glaucoma with cataract were enrolled in this study.Among them,85 patients(91 eyes,observation group) were treated with modified trabeculectomy with the resection of deep scleral resection and 60 patients (60 eyes,control group) were treated with routine trabeculectomy.The visual acuity,intraocular pressure (IOP),type of filtering bleb and postoperative complication were compared.Results There was significant difference in the visual acuity ＜ 0.1,0.4-0.5,＞ 0.5 between after operation for 1 month and before operation in two groups (P ＜ 0.05).but there was no significant difference in the visual acuity 0.1-0.3 (P ＞ 0.05).The IOP before operation in observation group was (29.6 ± 4.1) mmHg (1 mmHg =0.133 kPa),12 months after operation was (13.1 ± 4.9) mmHg,the degree of decrease was (16.6 ± 5.0) mmHg.The IOP before operation in control group was (30.4 ± 6.3) mmHg,12 months after operation was (18.9 ± 3.0) mmHg,the degree of decrease was (10.4 ± 4.0) mmHg.The IOP after operation and the degree of decrease between two groups had significant difference (P ＜ 0.05).The functional filtering bleb(Ⅰ type and Ⅱ type) in observation group was 77 eyes(84.6％,77/91),and 51 eyes(85.0％,51/60) in control group,there was no significant difference (P ＞ 0.05).After operation for 1 month,there was 8 eyes appeared transient hypotony in observation group and 5 eyes in control group,there was no significant difference (P ＞ 0.05).Conclusion The modified trabeculectomy in advanced stage angle-close glaucoma with cataract can reduce IOP more effectively and not increase the intraoperative risk and postoperative complication.
