ABSTRACT
Objective:To investigate the clinical significance of the serum platelet-derived growth factor BB (PDGF-BB) level in the diagnosis and treatment monitoring of non-small cell lung cancer (NSCLC) patients.Methods:Serum samples of 111 NSCLC patients in Xuzhou Cancer Hospital of Jiangsu Province and 105 healthy controls from Outpatients Department of Nanjing Yian Medical Examination Center between October 2014 and December 2017 were collected. Luminex assay was used to determine PDGF-BB level in serum samples of NSCLC patients and the healthy controls as well as patients after platinum chemotherapy. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic value of serum PDGF-BB level in patients with NSCLC, and the relationship of serum PDGF-BB level with clinicopathological features of NSCLC patients and platinum chemotherapy and effect was analyzed.Results:Compared to the healthy controls, serum PDGF-BB level was decreased in NSCLC patients [(54±24) ng/ml vs. (125±61) ng/ml, t = 11.09, P < 0.01], and the area under the ROC of serum PDGF-BB level on the diagnosis of NSCLC was 0.890. There were no significant differences in serum PDGF-BB level among NSCLC patients with different gender, age or lymph node metastasis (all P > 0.05); the serum PDGF-BB level in patients with high TNM stage was lower than that in patients with low TNM stage, and the serum PDGF-BB level in patients with low differentiation degree was lower than that in patients with high differentiation degree (all P < 0.05). Serum PDGF-BB level was continued to decrease in NSCLC patients after treatment with platinum-based chemotherapy. Conclusion:Serum PDGF-BB level of NSCLC patients is decreased, and it has a certain clinical significance in the early diagnosis of NSCLC.
ABSTRACT
Refractory macular holes typically represent macular holes larger than 400 μm, macular holes in pathological myopic eyes or complicated with myopic schisis, chronic holes longer than 6 months, persistent macular holes after surgeries, and some subtypes of secondary macular holes. A routine pars plana vitrectomy combined with internal limiting membrane peeling yielded a lower closure rate and unsatisfying visual rehabilitation in patients with refractory macular holes, which raised concerns among vitreoretinal surgeons. This editorial reviewed the new upcoming surgical techniques which were reportedly to improve the anatomical and visual prognosis of major subtypes of refractory macular holes. Although with a great variability, these surgical techniques are based the following surgical strategies: firstly, to sufficiently unravel the epi-macular tractional force; secondly, to bridge the defect of neurosensory retina by tissue insertion or implantation and stimulate wound healing process; thirdly, proper tamponade of gas or silicone oil so that the surface tension can stabilize the inserted or implanted tissue and encourage closure of the holes. In conclusion, surgical strategies for refractory macular holes should be made after a comprehensive consideration and a customized design.
ABSTRACT
Objective@#To evaluate the efficacy and safety of apatinib combined with chemotherapy in the first-line treatment of advanced non-small cell lung cancer (NSCLC) with negative driving genes.@*Methods@#From January 2016 to March 2018, 62 advanced NSCLC patients with negative driving genes diagnosed at Xuzhou Cancer Hospital were randomly divided into study group (30 cases) and control group (32 cases), respectively. The patients in the study group were treated with standard first-line chemotherapy combined with apatinib, while those in control group were treated with chemotherapy alone.@*Results@#The disease control rate (DCR) and objective remission rate (ORR) in the study group were 60.0% and 16.7%, respectively, higher than 46.9% and 9.3% in the control group, but without statistical difference (P>0.05). The median progression-free survival (PFS) of study group and control group were 6.4 months and 4.9 months, respectively (P=0.004), and the median overall survival (OS) were 11.3 months and 9.2 months, respectively (P=0.006). Multivariate survival analysis indicated that treatment regimen (P=0.001) was the independent prognostic factor of PFS, and PS score (P=0.002), clinical stage (P=0.02) and treatment regimen (P<0.001) were the independent prognostic factors of OS. After treatment, the incidence of hypertension and hand-foot syndrome in the study group were 46.7% and 53.3%, respectively, significantly higher than 3.3% and 0 in the control group, respectively (P<0.05). The incidence of grade 3-4 adverse drug reactions (ADRs) in the study group was 26.7% (8/30), mainly including hypertension, hand-foot syndrome and bone marrow suppression. The incidence of grade 3-4 ADRs in the control group was 15.6% (5/32), all of which were bone marrow suppression, without significant difference (P=0.286). There was no difference in serum levels of VEGF and CEA between the two groups before treatment. After treatment, the serum level of VEGF in the study group was (169.3±10.1) pg/ml, lower than (211.8±16.7) pg/ml of the control group (P<0.05).@*Conclusion@#Apatinib combined with first-line chemotherapy for advanced NSCLC patients with negative driving genes is safe and beneficial for survival. This therapeutic strategy can significantly prolong the PFS and OS, and further improvement and application can be considered as a choice in the clinical treatment.
ABSTRACT
Objective@#To evaluate the 5-year survival and success rates of transplanted autologous teeth with complete root formation.@*Methods@#A total of 32 patients admitted to the hospital for 36 cases of tooth autotransplantation with complete root formation from November 2008 to October 2012 were enrolled in this study. Clinical and radiographic examinations were performed during the post-operative follow up periods of 1 month, 3 months, 6 months, 9 months and 12 months, respectively. Survival analysis was then conducted and the predictive factors influencing prognosis from the aspects of age, sex and root canal treatment status were investigated. Kaplan-Meier survival curve was adopted for survival analysis and Log-Rank test was used to compare the survival rate and success rate of each single factor.@*Results@#According to each case′s last follow-up, the 5-year survival rate of autotransplanted teeth with complete root formation was 83%. Within these cases, the 5-year success rate of the autotransplanted teeth with no apparent periodontitis or apical periodontitis, and the crown to root ratio being less than 1 was 65%. Factors of age and sex of the patients showed no correlation with the prognosis of autotransplantation (P>0.05). Root canal treatment was crucial in preventing transplanted teeth from apical periodontitis and root resorption, and accordingly increased the success rate (P=0.028) of autotransplantation.@*Conclusions@#Autotransplantation with complete root formation has a high 5-year survival rate, and is a viable and alternative method for restoration of tooth loss. Post-operative follow-up should be thoroughly planned and root canal treatment should be performed in order to increase the survival rate and success rates of autotransplantation.

Methods A self-designed questionnaire about training effects was used to investigate 149 oncology specialist nurses in 48 hospitals in Shandong province. Results The total score of training effects was 202.075 ± 17.918. Differences were significant in human relations of training effects of oncology specialist nurses (F=3.439,P<0.05 ). 94.74％(126/133)of the oncology specialist nurses had no changeable in their work after training, 62.41％(83/133)served as skeleton staffs, only 22.56％(30/133)published in journals, 58.65％(78/133)of the specialist nurses had no chance to attend meeting and only 3.01％(4/133)had experiences to study for a month or more. Conclusions The training effects of Shandong oncology specialist nurses some abilities still need to be increased, the training contents need to be enriched, the use and management of the specialist nurses need to be further regulated, and the development of the oncology specialist nurses need to be further improved.
ABSTRACT
Objective To investigate the clinical manifestations and gene mutation of a pedigree with retinal lattice degeneration and granular corneal dystrophy (GCD) type 2.Methods Ten members in 3 generations of a pedigree with retinal lattice degeneration and GCD2 were included in the study, including 6 patients (3 males and 3 females) and 4 healthy family members. All members underwent visual acuity, slit lamp microscope, three-mirror lens, fundus color photography, optical coherence tomography, and corneal endothelial cells counting. Genomic DNA was extracted from peripheral venous blood (2 ml) from all the subjects and their spouses, who had no related inherited diseases. The next generation sequencing method was used to detect the mutation sites of transforming growth factor β (TGFBI), and all results underwent Sanger verification.Results Among the 12 eyes of 6 patients, the visual acuity was FC/20 cm-1.0. In the superficial central corneal stroma, snowflake-like deposits were observed in three cases (6 eyes), and a small amount of granular deposits were observed in three cases (6 eyes). Corneal endothelial cell counts were normal. Retinal lattice degeneration were observed in 3 cases, 6 eyes (including 3 cases of rhegmatogenous retinal detachment in 4 eyes); retinal thinning without obvious lattice degeneration in 4 eyes of 2 patients. Nystagmus in 1 patient and fundus examination showed no significant abnormalities. DNA sequencing results showed that the proband and 4 patients had missense mutation of TGFBI gene in exon 4 c.371G> A, the mutation site corresponding to the amino acid change encoded by TGFBI gene No. 124 Amino acids, from arginine to histidine (p.R124H). Patients with this mutation have varying degrees of clinical phenotype.Conclusions The mutation of c.701G> A (p.R124H) in TGFBI gene is the causative gene of GCD in this pedigree. The patients with this mutation have different clinical phenotypes.
ABSTRACT
Vitreous hemorrhage in children is caused by trauma or non-traumatic factors.Long-term vitreous hemorrhage not only affects children's vision,but also can lead secondary glaucoma,traumatic retinal detachment and other serious complications.Ocular trauma,some ocular and systemic diseases are the common etiology leading to vitreous hemorrhage in children.A small amount of vitreous hemorrhage can be treated by observation and conservative treatment.However,if the vitreous hemorrhage has no obvious absorption or serious complications appeared,it needs to be treated by surgery.The choice of treatment time and methods need to be further studied.
