Objective To explore the distributions of C AG polymorphisms of androgen receptor gene in Chinese population and the relatio nship with prostate cancer (CaP). Methods The number of CAG repeats were measured in 105 cases with CaP and 190 matched case-control b y PCR、DHPLC and Sequencing analysis,and its association with the susceptibility to CaP. Results The average number of CAG repeats was 2 2.7 in CaP and 23.3 in control group ( P =0.22).Men with CAG repeats lengt h less than 22 may be in high risk of prostate cancer (odds ratio,2.39;95%CI 1.1 9~4.81, P =0.012),compared with men CAG repeats length of 22 or more. Conclusions A less CAG repeat length (

Objective:To explore the significance of the clinical target volume (CTV) dose optimization in the upper and middle neck in protecting the laryngopharynx, anterior and posterior rings during intensity-modulated radiotherapy (IMRT) and multimodal imaging system for nasopharyngeal carcinoma.Methods:Clinical data of 298 nasopharyngeal carcinoma patients admitted to Jiangsu Cancer Hospital from 2016 to 2018 were retrospectively analyzed. According to the following five strategies of CTV dose optimization in the upper and middle neck: group A, complete optimization of bilateral cervical lymph nodes (CLNs), that is, the CTV doses of bilateral CLNs were 50.4 Gy; group B, complete optimization of unilateral CLNs, that is, the CTV dose of unilateral CLNs was 50.4 Gy and the contralateral CLNs was 60 Gy; group C, incomplete optimization of bilateral CLNs, that is, the CTV doses of bilateral CLNs were 50.4 Gy, while the suspicious positive CLNs were selectively boosted to 60 Gy; group D, incomplete optimization of unilateral CLNs, that is, the CTV dose of unilateral CLNs was 50.4 Gy and the suspicious positive CLNs were selectively boosted to 60 Gy, and the CTV dose of contralateral side was 60 Gy; group E: no optimization, that is, the CTV doses of bilateral CLNs were 60 Gy.Results:Among 298 patients, 215 patients received dose optimization and 83 cases did not receive dose optimization. In the dose optimization schemes, 114 cases were assigned in group A, 36 cases in group B, 60 cases in group C and 5 cases in group D. The median (range) follow-up time was 28.5(6.0-46.3) months. The overall survival rate was 95.6%, the progression-free survival rate was 84.2% and the locoregional control rate of CLNs was 98.0%. Local relapse of CLNs occurred in six patients, including 1 case of retropharyngeal lymph node, 4 cases of Ⅱ area and 1 case of Ⅳ area. The P values of average dose of laryngopharynx in group A, group B, group C and group D compared with that in group E were<0.001, 0.016, 0.001 and 0.572, respectively. The P values of the average dose of the anterior ring in group A, group B, group C and group D compared with that in group E were<0.001, 0.011, <0.001 and 0.805, respectively. The P values of the average dose of the posterior ring in group A, group B, group C and group D compared with that in group E were<0.001, 0.004, <0.001 and 0.252, respectively.Conclusions:Combined with the metastatic rules of CLNs and multimodal imaging system, it is safe to optimize the CTV dose of the upper and middle neck during IMRT in nasopharyngeal carcinoma patients, which can significantly reduce the doses of laryngopharynx, anterior and posterior rings, thereby providing evidence for reducing the CTV dose in the upper and middle neck.

OBJECTIVETo investigate the effect and clinical significance of glucocorticoid on CD4+CD25+ regulatory T cells (Tregs) in patients with hepatitis B virus (HBV)-related pre-liver failure.
METHODSThe subjects of this study included 78 patients with pre-liver failure induced by HBV (cases) and 24 healthy individuals (controls). Among the 78 cases, 42 received glucocorticoid treatment and 36 did not. Between-group differences in Tregs (in peripheral blood) were evaluated by flow cytometry and statistical analysis.
RESULTSTwo weeks of glucocorticoid treatment led to an increase in Treg level compared to baseline (before therapy: 2.76 ± 0.73 vs. 3.88 ± 1.60). In addition, after the two weeks of glucocorticoid treatment, the Treg level of improved patients was significantly higher than that measured at baseline (before therapy: 2.70 ± 0.77 vs 3.97 ± 1.59, P < 0.05).
CONCLUSIONGlucocorticoids up-regulate the expression of Treg cells, which may contribute to the immunological mechanism that protects pre-liver failure patients from deterioration of their condition. Careful inspection and monitoring of Treg levels may help improve prognosis of these patients.

ObjectiveTo investigate the association between mean platelet volume (MPV) and prognosis of hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF) and the value of MPV in prognostic evaluation. MethodsA retrospective analysis was performed for the clinical data of 37 patients with hepatitis B cirrhosis, 44 patients with HBV-ACLF, and 27 patients with chronic hepatitis B, who were admitted to Department of Infectious Diseases, The First Affiliated Hospital of Soochow University, from January 2015 to December 2019, as well as 24 individuals who underwent physical examination during the same period of time. Related clinical data included sex, age, total bilirubin (TBil), creatinine (Cr), blood urea nitrogen (BUN), albumin (Alb), blood ammonia (NH3), routine blood test results, Model for End-Stage Liver Disease (MELD) score, and blood coagulation parameters. According to prognosis, the patients with HBV-ACLF patients were divided into improvement group with 19 patients and non-improvement group with 25 patients, and the patients were followed up for 3 months. The Kruskal-Wallis H test was used for comparison between multiple groups, and the Wilcoxon rank sum test was used for comparison within each group, the Mann-Whitney U test was used for comparison between two groups; a binary logistic regression analysis was used to investigate the independent influencing factors for prognosis, and the receiver operating characteristic (ROC) curve was used to predict the accuracy of variables. ResultsThere were significant differences in MPV, platelet count, prothrombin time (PT), international normalized ratio (INR), Alb, BUN, TBil, and MELD score between the liver cirrhosis group, the HBV-ACLF group, the chronic hepatitis group, and the healthy group (χ2=39.031, 75.837, 59.894, 56.033, 22.760, 83.353 and 70.299, all P<0.001). Further comparison of MPV between two groups showed that the HBV-ACLF group had a significantly higher MPV than the healthy group and the chronic hepatitis group (Z=9.076 and 4.435, both corrected P<0.001), and the liver cirrhosis group had a significantly higher MPV than the healthy group (Z=2.646, corrected P=0.049). For the patients with HBV-ACLF, there were significant differences in MPV, age, PT, INR, and MELD score between the improvement group and the non-improvement group (Z=-3.710, -2.726, -2.678, -2.322 and -2.610, all P<0.05), and further binary logistic regression analysis showed that MPV (odds ratio [OR]=1.175, 95% confidence interval [CI]: 1.067-2.756, P=0.026) and MELD score (OR=1.643, 95% CI: 1.021-2.644, P=0.041) were independent influencing factors for the prognosis of HBV-ACLF. MPV alone, MELD score alone, and MPV combined with MELD score had an area under the ROC curve of 0.742, 0.731, and 0.791, respectively, in predicting the prognosis of HBV-ACLF, and MPV combined with MELD score had relatively high sensitivity (0.72) and specificity (0.895). ConclusionMPV is an independent influencing factor for the prognosis of HBV-ACLF and has a good value in predicting prognosis. MPV combined with MELD score has advantages over MPV or MELD score alone in predicting the prognosis of HBV-ACLF.
