Abstract
Objective: To compare the prognostic influence and postoperative pathology of different comprehensive treatment models for adenocarcinoma of esophagogastric junction. Methods: Between January 2012 and December 2017, a total of 219 patients with adenocarcinoma of esophagogastric junction underwent surgery in Gastrointestinal Cancer Center, Peking University Cancer Hospital & Institute and were enrolled in this study. The clinicopathological data of these patients were collected. The patients were categorized into 3 groups according to different treatment models: surgery-first group, neoadjuvant chemotherapy (NAC) group and neoadjuvant chemoradiotherapy (nCRT) group. A trimatch propensity score analysis was applied to control potential confounders among the three groups by using R language software. A total of 7 covariates including gender, age, comorbidity, body mass index, clinical T stage, clinical N stage and Siewert type were included, and the caliper value was taken as 0.2. After matching, a total of 87 patients were included for analysis with 27 patients for each group. There were 82 males and 5 females, with a median age of 63 years (range: 38 to 76 years). The effect of preoperative treatment on postoperative tumor pathology among the three different comprehensive treatment models was explored by χ2 test, ANOVA or Wilcoxon rank sum test. Mann-Whitney U test or χ2 test were used to undergo pairwise comparisons. Kaplan-Meier method and Log-rank test were used to analyze the overall survival and progression-free survival. Results: The proportion of vascular embolism in the surgery-first group was 72.4% (21/29), which was significantly higher than NAC group (37.9% (11/29), χ2=6.971, P=0.008) and nCRT group (6.9% (2/29), χ2=26.696, P<0.01). The proportions of pathological T3-4 stage in nCRT group and NAC group were 55.2% (16/29) and 62.1% (18/29), respectively, which were significantly lower than the surgery-first group (93.1% (27/29), χ2=10.881, P=0.001; χ2=8.031, P=0.005). Compared with the NAC group (55.2% (16/29), χ2=6.740, P=0.009) and nCRT group (31.0% (9/29), χ2=18.196, P<0.01), the proportion of lymph node positivity 86.2% (25/29) were significantly higher in the surgery-first group. The 5-year overall survival rates were 62.1%, 68.6% and 41.4% for the surgery-first group, NAC group and nCRT group, respectively (χ2=4.976, P=0.083). The 5-year progression-free survival rates were 61.7%, 65.1% and 41.1% for the surgery-first group, NAC group and nCRT group, respectively. The differences in overall survival (χ2=4.976, P=0.083) and progression-free survival (χ2=4.332, P=0.115) among the three groups were nonsignificant. Conclusions: Postoperative pathology is significantly different among the three groups. Neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy could decrease the proportions of vascular embolism, pathological T3-4 stage and lymph node positivity to achieve local tumor control. The prognosis of overall survival and progression-free survival are not significantly different among the three groups.

Abstract
Objective: To investigate the spectrum of gene mutations in adult patients with B-acute lymphoblastic leukemia (B-ALL), and to analyze the influences of different gene mutations on prognosis. Methods: DNA samples from 113 adult B-ALL patients who administered from June 2009 to September 2015 were collected. Target-specific next generation sequencing (NGS) approach was used to analyze the mutations of 112 genes (focused on the specific mutational hotspots) and all putative mutations were compared against multiple databases to calculate the frequency spectrum. The impact of gene mutation on the patients' overall survival (OS) and recurrence free survival (RFS) was analyzed by the putative mutations through Kaplan-Meier, and Cox regression methods. Results: Of the 113 patients, 103 (92.0%) harbored at least one mutation and 29 (25.6%) harbored more than 3 genes mutation. The five most frequently mutated genes in B-ALL are SF1, FAT1, MPL, PTPN11 and NRAS. Gene mutations are different between Ph+ B-ALL and Ph- B-ALL patients. Ph- B-ALL patients with JAK-STAT signal pathway related gene mutation, such as JAK1/JAK2 mutation showed a poor prognosis compared to the patients without mutation (OS: P=0.011, 0.001; RFS: P=0.014,<0.001). Patients with PTPN11 mutation showed better survival than those without mutation, but the difference was not statistically significant (P value > 0.05). Besides, in Ph+ B-ALL patients whose epigenetic modifications related signaling pathway genes were affected, they had a worse prognosis (OS: P=0.038; RFS: P=0.047). Conclusion: Gene mutations are common in adult ALL patients, a variety of signaling pathways are involved. The frequency and spectrum are varied in different types of B-ALL. JAK family gene mutation usually indicates poor prognosis. The co-occurrence of somatic mutations in adult B-ALL patients indicate the genetic complex and instability of adult B-ALL patients.

Abstract
Objective: To observe the early immunological rejection prevention effect of tacrolimus eye drops combined with glucocorticoids on fungal keratitis patients who received penetrating keratoplasty (PKP). Methods: In a retrospective case series study, medical records of fungal keratitis patients who received PKP in Shandong Eye Institute from March 2013 to December 2015 were reviewed. Twenty-six patients (26 eyes) were given tacrolimus eye drops, and 24 patients (24 eyes) were given 1% cyclosporine A eye drops immediately after PKP. Two weeks after PKP, these patients were given low concentration of glucocorticoids if no fungal recurrence was found. Immune rejection, fungal recurrence, intraocular pressure, and drug irritation symptoms were monitored. Data were analyzed by chi-square test and independent t-test. Results: The average follow-up was 7 months (range, 3 to 12 months) postoperatively. The rejection rate was 15.3% in the tacrolimus group and 47.8% in the cyclosporine A group (χ(2)=5.510, P<0.05). One patient in the tacrolimus group and two patients in the cyclosporine A group suffered fungal recurrence. Two patients in the tacrolimus group and four patients in the cyclosporine A group had secondary glaucoma. The intraocular pressure was controlled. Three patients receiving tacrolimus eye drops and 13 patients receiving cyclosporine A eye drops had mild irritation symptoms. Conclusions: Tacrolimus eye drops combined with low concentration of glucocorticoids can prevent the early immunological rejection after PKP for fungalkeratitis effectively and safely.
