ABSTRACT
BACKGROUND@#Till date, the optimal treatment strategy for delivering adjuvant androgen deprivation therapy (ADT) in localized and locally advanced prostate cancer (PCa), as a lower stage in PCa progression compared with metastatic PCa, is still unclear. This study compares the efficacy of castration alone with complete androgen blockade (CAB) as adjuvant ADT in patients with localized and locally advanced PCa undergoing radical prostatectomy (RP).@*METHODS@#Patients diagnosed with PCa, without lymph node or distant metastasis, who received RP in West China Hospital between January 2009 and April 2019, were enrolled in this study. We performed survival, multivariable Cox proportional hazard regression, and subgroup analyses.@*RESULTS@#A total of 262 patients were enrolled, including 107 patients who received castration alone and 155 patients who received CAB. The survival analysis revealed that there was no significant difference between the two groups (hazard ratios [HR] = 1.07, 95% confidence intervals [95% CI] = 0.60-1.90, P = 0.8195). Moreover, the multivariable Cox model provided similarly negative results before and after adjustment for potential covariant. Similarly, there was no significant difference in the clinical recurrence between the two groups in both non-adjusted and adjusted models. Furthermore, our subgroup analysis showed that CAB achieved better biochemical recurrence (BCR) outcomes than medical castration alone as adjuvant ADT for locally advanced PCa (P for interaction = 0.0247, HR = 0.37, 95% CI = 0.14-1.00, P = 0.0497).@*CONCLUSION@#Combined androgen blockade achieved better BCR outcomes compared with medical castration alone as adjuvant ADT for locally advanced PCa without lymph node metastasis.

Objective To study the effects of different parenteral nutrition on acute inflammatory response,immune cells and lipid metabolism in patients after pancreaticoduodenectomy.Methods Eighty patients after pancreaticoduodenectomy were divided into study group and control group,with 40 cases in each group.Structural fat emulsion was used in study group and medium/long chain fat emulsion in control group.The changes of acute inflammation,immune cells and lipid metabolism were compared between the two groups.Results (1)The levels of C-reactive protein (CRP) and serum prostaglandin E2 (PGE2) in the two groups were significantly higher on the first day after operation than those before operation.The difference between the two groups was statistically significant (P ＜ 0.05).The level of CRP and PGE2 decreased to the preoperative level on the seventh day after operation,but the decline rate in the study group was significantly faster than that in the control group (P ＜ 0.05).(2) The levels of CD3 +,CD4 +,CD8 +,CD4 +/CD8 + in the study group were significantly higher than those in the control group (P ＜ 0.05).(3) After 3-7 days of intravenous parenteral nutrition infusion,the blood lipid level was significantly lower in study group (P ＜ 0.05).Conclusion Structural fat emulsion alleviates the inflammatory reaction in patients after pancreaticoduodenectomy,promotes the recovery of immunity,significantly reduces the level of blood lipids.
ABSTRACT
Objective To analyze the relationship between the level of microRNA-29b in circulation and left ventricular hypertrophy in hypertensive patients.Methods A total of 240 subjects from Henan Province People's Hospital from June 2015 to June 2018 were included in the present study.Among them,160 were hospitalized patients,and were divided into two groups.Patients with simple hypertension and had no left ventricular hypertrophy (80 cases) were in the simple hypertension group (HBP-NLVH),and patients with hypertension combined with left ventricular hypertrophy (80 cases) were in the high blood pressure with left ventricular hypertrophy group (HBP-LVH).Normal control subjects (80 cases) were those with no hypertension and randomly selected from the medical center of Henan Province People's Hospital.Serum microRNA-29b expressions were detected by real time fluorescence quantitative PCR.The thickness of interventricular septum (IVSD) and left ventricular posterior wall thickness (LVPWD) were measured by echocardiography.Results Compared with the normal control group (1.95±0.79),the relative expression of microRNA-29b in the patients both in the HBP-NLVH group (2.67±0.92) and the HBP-LVH group (5.12 ± 1.23) was up-regulated,and the difference between normal control and patients was statistically significant (P＜0.05).In patients,the microRNA-29b level in the HBP-LVH group was significantly higher than that in the HBP-NLVH group (P＜0.05).The expression level of microRNA-29b was positively correlated with IVSD (r=0.71,P＜0.05) and LVPWD (r=0.74,P＜0.05),respectively.The sensitivity and specificity of serum microRNA-29b levels in the diagnosis of left ventricular hypertrophy in hypertension patients were 96.8％ and 91.3％,respectively.Conclusion Serum microRNA-29b level is elevated in hypertensive patients with left ventricular hypertrophy,and is positively correlated with left ventricular hypertrophy.The circulation microRNA-29b might be a useful biomarker with prognostic value in left ventricular hypertrophy in hypertension patients.

ABSTRACT
Objective To establish an external quality assessment ( EQA) system of genitourinary tract secretions routine testing in Guizhou Province and improve the overall testing level.Methods From 2009 to 2011, more than 50 clinical laboratories in different grade hospitals from Guizhou Province were enrolled as participating units every year.EQA was carried out twice a year.Each time, five slides of high quality Wright′s or Gram stain smear of the genitourinary tract secretions or photographs obtained from these smears were selected to send to the participating laboratories for testing, and the feedback results from each laboratory were analyzed.The qualification was judged by the coincidence rate equal to or more than 80%. The average coincidence rates of each time and each year were statistically analyzed by Chi-squared test. Results From 2009 to 2011, the number of EQA participating units increased from 55 to 96, with an average return rate of >80%.Coincidence rates <80%of the 6 EQA results in the 3 years were as follow:four times for coccobacteria (73.7%,77.8%,61.1%,77.1%), twice for bacillus (75.6%,79.3%) and coccobacillus (64.3%,52.1%), once for infusorian (79.7%), epithelial cells (76.1%), neutropenia (75.7%) and cleanliness (71.3%).There were six batches of 30 quality assessment controls (accounting for 20.0%) in the six EQAs had the coincidence rate of <80%.Eleven items of 30 quality assessment controls with 1 to 15 batches were unqualified ( average coincidence rate of<80%) respectively.The item with the highest total average coincidence rate was suspected gonococcus (94.2%), and two items with the lowest total average coincidence rates were coccus and coccobacillus ( 77.0%, 75.2%, respectively ) . Conclusions This EQA program carried out within a certain range of clinical laboratories achieved good results:participating units increased significantly;the total score of all the items showed an obviously upward trend;the quality awareness of clinical lab technicians has enhanced to a certain extent.In this study, EQA system of genitourinary tract secretion routine testing were preliminarily established in Guizhou province, which provided a reference model of internal quality control ( IQC ) and EQA for clinical laboratories and higher authorities, and will be bound to have a positive impact on improvement of the overall level of genitourinary tract secretion routine testing.
