ABSTRACT
Objective:To explore and analyze the changes of miRNA-138 and miRNA-26b before and after transsphenoidal surgery for pituitary tumors and their clinical significance.Methods:86 patients with functional pituitary tumors who underwent transsphenoidal surgery in Linyi People’s Hospital from Apr. 2020 to Apr. 2021 were retrospectively analyzed. The recurrence within 1 year after operation was followed up and the patients were divided into unrecovered group (24 cases) and cured group (62 cases) . Clinical data such as age, gender, tumor pathological type, Knosp grade, first operation, tumor diameter, intraoperative tumor residue, Ki-67 and adjuvant therapy were collected. Fasting venous blood was collected before surgery and the next morning after surgery. Quantitative real-time PCR was used to detect the serum levels of mircoRNA-138 (miRNA-138) and miRNA-26b (mirNA-26B) , and the changes of serum miRNA-138 and miRNA-26b levels before and after surgery. Univariate and multivariate logistic regression were used to analyze the relationship between serum miRNA-138 and miRNA-26b levels and postoperative prognosis, and ROC curve was drawn to analyze their predictive value for postoperative prognosis.Results:Univariate analysis showed that Knosp grade, tumor diameter, intraoperative tumor residual, Ki-67, and adjuvant therapy were associated with the recurrence of body tumor after transsphenoidal surgery ( P<0.05) . After operation, the expression of miRNA-138 in serum was higher than that before operation, and the expression of miRNA-138 in unhealed group (4.13±1.12) was higher than that in cured group (3.56±0.84) ( P<0.05) . The expression of miRNA-26b in serum after operation was lower than that before operation, and the expression of miRNA-26b in the unhealed group (2.34±0.62) was lower than that in the cured group (2.75±0.58) ( P<0.05) . Pituitary tumor hormone increased before operation and returned to normal after operation. Multivariate logistic regression analysis showed that tumor diameter ≥40cm (OR=3.476, 95%CI: 1.267-9.539) , postoperative tumor residual (OR=3.155, 95%CI: 1.236-8.052) , Ki-67≥3% (OR=3.885, 95%CI: 2.038-7.403) , postoperative serum miRNA-138 expression ≤3.62 (OR=2.323, 95%CI: 1.536-3.513) , postoperative serum miRNA-26b expression ≥2.59 (OR0.453, 95 %CI: 0.286-0.717) was an independent risk factor for the recurrence of pituitary tumors after transsphenoidal surgery ( P<0.05) . When the optimal cut-off value of serum miRNA-138 was 3.62, the area under the curve for predicting the recurrence of pituitary tumors after transsphenoidal surgery was 0.78, the sensitivity was 81.35%, and the specificity was 71.46%; the optimal cut-off value of serum miRNA-26b When it was 2.59, the area under the curve for predicting and predicting the recurrence of pituitary tumors after transsphenoidal surgery was 0.75, at this time, the sensitivity was 78.62%, and the specificity was 72.33%. The lower area was 0.83, the sensitivity was 85.47%, and the specificity was 72.38%. Conclusion:The expression of serum miRNA-138 was up-regulated and the expression of miRNA-26b was down-regulated after transsphenoidal surgery for pituitary tumors, and its abnormal expression was associated with postoperative recurrence, which has a good predictive value for predicting postoperative recurrence.
ABSTRACT
Objective To explore the clinical significance and gene mutation profiles of renal transplant patients with unconjugated hyperbilirubinemia (Gilbert's syndrome).Methods Genomic DNA was extracted from peripheral blood samples of 8 renal transplant patients with Gilbert'S syndrome.UGT1A1 * 6 and UGT1A1 * 28 genotypes were identified through digital fluorescence molecular hybridization and DNA sequencing.Results There are 2 cases of UGT1A1 * 28 heterozygous mutant,3 cases of UGT1A1 * 6 homozygous mutant,2 case of UGT1A1 * 6 heterozygous mutant,1 case of UGT1A1 * 28 heterozygous mutant combined with UGT1A1 * 6 heterozygous mutant.Conclusion There is a higher heterozygous or homozygous gene mutation rate of UGT1A1 * 6 and UGT1A1 * 28 in renal transplant patients with Gilbert's syndrome.Genetic mutation of UGT1A1 * 6 and UGT1A1 * 28 may be the reason of Gilbert's syndrome after renal transplant.
ABSTRACT
Objective To evaluate the clinical significance of simultaneous transurethral resection (TUR) of a bladder tumor and the prostate in the treatment of non-muscle invasive bladder cancer with benign prostatic hyperplasia (BPH).Methods Patients were divided into two groups.Group A contained 46 male patients who accepted TUR for the treatment of both bladder cancer and benign prostatic hyperplasia.Group B contained 69 male patients who accepted TURBt only.Clinical data were retrospectively collected and analyzed to compare clinical outcomes and safety in these two groups.Results The bladder cancer recurrence rates in group A and B were 50.0％ and 50.7％,the average recurrence free time was 20 and 18 months,and the progression rates were 6.5％ and 7.2％,respectively.There were no significant differences between the two groups for either average recurrence free time or progression rates (P ＞ 0.05).Recurrences in the prostatic urethra were found in two cases in group A and one case in group B and all three cases were in T1 G3.Conclusions Simultaneous TUR for bladder tumor and the prostate can be safely and effectively performed in terms of oncologica] control in patients who have non-muscle invasive and low grade bladder tumors ( T1G1 - G2 ) with lower urinary tract obstruction caused by BPH.But this procedure should be cautiously performed on patients with T1 G3 bladder tumors.
ABSTRACT
ObjectiveTo investigate the efficacy of retention enema with rhubarb for severe acute pancreatitis (SAP) with intestine paralysis.MethodsTotally 60 patients with SAP since last five years were included,and then they were randomly divided into control group and treatment group with 30 patients in each group.Patients in control group received routine treatment of SAP,including fasting,gastrointestinal decompression,antibiotics,inhibition of pancreatic secretion,inhibition of SIRS and organ support.Patients in treatment group received additional retention-enema with rhubarb (200mL soak solution by 100g rhubarb),once daily until the recovery of bowel function.The bladder pressure ( the 1,2,5 and 6 days after admission)was evaluated,and APACHE Ⅱ score was determined.The recovery of bowel function ( the bowel sounds,the flatus and defecation of intestinal tract),SIRS recovery time,hospital stay,and the mortality were observed.ResultsAt the 5 and 6 days after admission,the bladder pressure and APACHE Ⅱ score in treatment group were significantly lower than those in control group [ (21.9 ±9.0)cmH2O vs (25.3 ±9.5)cmH2O,( 16.5 ±7.5)cmH2O vs (20.6 ±7.7)cmH2O,1 cmH2O =0.098 kPa; (9.8 ±3.8) vs (12.5 ±3.6),(9.2 ±2.4)vs ( 11.2 ± 2.5 ),P ＜ 0.05 ) ].The recovery time of bowel function and SIRS recovery time,hospital stay,and the mortality in treatment group were ( 126.8 ± 28.2 ) h,( 131.2 ± 29.6) h,( 25.6 ± 6.2) d and 16.7 ％,and the recovery time of bowel function and SIRS recovery time,hospital stay were significantly lower than those in control group [ ( 169.9 ± 53.4 ) h,( 160.4 ± 30.4) h,( 33.2 ± 6.4) d,P ＜ 0.05 ).The mortality was reduced,but the difference between the two groups was not statistically significant ( 26.7％,P ＞ 0.05 ).ConclusionsThe retention-enema with rhubarb can accelerate the recovery time of bowel function of SAP patients and reduce the hospital stay.
