Objective:
The aim of this study was to investigate the association of the CYP19A1 rs7176005 single nucleotide polymorphism (SNP) with breast cancer risk and with clinicopathologic features of tumors.
Methods:
This study was conducted by including 138 patients with breast cancer (cancer group), those who diagnosed as primary breast cancer after operation by pathology. There were 293 cases in the group of benign breast disease which was presented as a solid mass by the color ultrasound and pathologically diagnosed as "fibroadenoma or adenosis" (benign breast disease group), the cases were paired with breast cancer patients by age±5 in the same period, and there were 259 cases in the group of healthy control who received routine physical examination during the same period and were paired with breast cancer patients by age±5 without any detection of breast related diseases (healthy control group) at West China hospital between September 2012 and November 2016. The CYP19A1 rs7176005 SNP was detected by a direct sequencing method. Hardy-Weinberg test was used to analyze the genetic balance of the 3 groups. Chi square test was used to compare the distribution of rs7176005 genotypes between the 3 groups, and the differences of clinicopathological features in breast cancer patients carrying different genotypes.
Results:
The ages of the breast cancer cases, the benign breast disease group and the healthy control group were (44.69±8.09), (42.33±11.44) and (41.92±9.61) years old, respectively. Hardy-Weinberg equilibrium test identified that the composition ratios of alleles C and T in breast cancer group, benign breast disease group and healthy group were not statistically significant (χ2 values were 0.83, 0.34 and 0.04, respectively,

Objective:To study the clinical features of the "migration birds" population in Hainan Province in winter presenting with acute cholecystitis.Methods:Patients who were diagnosed to suffer from acute cholecystitis in the winter months from November to February of the following year of 2017, 2018 and 2019 and admitted in Hainan Hospital of Chinese PLA General Hospital were included in this study. The "migration birds" patients who arrived in Hainan Province in less than 30 days were defined as the short-term group ( n=49), 30-89 days as the mid-term group ( n=24), more than 90 days as the long-term group ( n=48). The general information, associated medical diseases, clinical presentations, interventional strategies and in-hospital outcomes were compared, and further analyze the clinical characteristics of patients with purulent cholecystitis and non-purulent cholecystitis in the short-term group. Results:Of 120 patients, there were 49 patients in the short-term group (29 males and 20 females with an average age of 65.18±15.02 years), 24 patients in the mid-term group (13 males and 11 females with an average age of 66.21±11.93 years), and 48 patients in the long-term group (30 males and 18 females with an average of 60.73±12.54 years). The general information, interventional strategies and in-hospital outcomes were similar among the three groups. When compared with patients in the long-term group, patients in the short-term group had higher incidences of hypertension [20.83% (10/48) vs 48.98% (24/49)] and diabetes [10.42% (5/48) vs 30.61% (15/49)]. The gallbladder wall in the short-term group was significantly thicker than that in the long-term group [0.60(0.40, 0.70) cm vs 0.50(0.30, 0.60) cm, P<0.017]. The proportion of purulent cholecystitis in the short-term group was significantly higher than that in the long-term group [48.15% (13/27) vs 17.24% (5/29) , P<0.017] . In the short-term group, the incidences of silt-like stones of purulent cholecystitis [38.46% (5/13) vs 14.29% (2/14)], gallbladder perforation [30.77% (4/13) vs 0], gallbladder gangrene [53.85% (7/13) vs 7.14% (1/14)], perigallbladder effusion [76.92% (10/13) vs 14.29% (2/14)], abdominal effusion [46.15% (6/13) vs 7.14% (1/14)] were significantly higher than that of patients with non-purulent cholecystitis, (all P<0.05). Conclusion:Patients presenting with acute cholecystitis after arrival in Hainan in the short term had more severe inflammation with complications of suppuration, perforation and gangrene. Patients with hypertension and diabetes were the high risk group of patients presenting with acute cholecystitis after short-term arrival in Hainan.
